Abstract:
A change in teaching delivery at a large Australian university, from two semesters to three trimesters, was the occasion for using more formative assessment in a core first-year mathematics unit. This study compared evidence about learning outcomes for two cohorts in adjacent years. Cohort 1 was the last taught over a semester, and Cohort 2 the first taught over a trimester. There was no change in overall workload, and no change in the unit's total teaching hours, syllabus or materials. Assessments were changed for class tests during the teaching period by giving Cohort 2 access to unlimited practice and computer-assisted feedback on the questions in the test database, followed by doing the tests under examination conditions. For Cohort 2, a written assignment was also added, focused on giving a clear solution to a mathematics problem, and awareness of the need for appropriate evidence, both background and internal to the problem. Learning outcomes were compared using closely comparable tasks from the final examinations, and examining students' answers in the examination scripts. Outcomes were assessed by a method derived from the solo taxonomy, which afforded a common scale to measure the quality of learning outcomes observable in final examination scripts. Results on separate tasks, plus those for a composite score, favoured Cohort 2. The effect size for the composite score was 0.457. This indicates that the unlimited practice with computer feedback for class tests, and the writing assignment, were functioning as intended in promoting learning with understanding. References S.

Abstract:
In this paper, we prove a generalization of a correspondence between holomorphic Jacobi cusp forms of higher degree (matrix index) and elliptic cusp forms obtained by K. Bringmann [Lifting maps from a vector space of Jacobi cusp forms to a subspace of elliptic modular forms, Math. Z.253 (2006) 735–752], for forms of higher levels (for congruence subgroups). To achieve this, we make use of the method adopted by M. Manickam and the first author in Sec. 3 of [On Shimura, Shintani and Eichler–Zagier correspondences, Trans. Amer. Math. Soc.352 (2000) 2601–2617], who obtained similar correspondence in the degree one case. We also derive a similar correspondence in the case of skew-holomorphic Jacobi forms (matrix index and for congruence subgroups). Such results in the degree one case (for the full group) were obtained by N.-P. Skoruppa [Developments in the theory of Jacobi forms, in Automorphic Functions and Their Applications, Khabarovsk, 1988 (Acad. Sci. USSR, Inst. Appl. Math., Khabarovsk, 1990), pp. 168–185; Binary quadratic forms and the Fourier coefficients of elliptic and Jacobi modular forms, J. Reine Angew. Math.411 (1990) 66–95] and by M. Manickam [Newforms of half-integral weight and some problems on modular forms, Ph.D. thesis, University of Madras (1989)].

Abstract:
The virtual element method is an extension of the finite element method on polygonal meshes. The virtual element basis functions are generally unknown inside an element and suitable projections of the basis functions onto polynomial spaces are used to construct the elemental stiffness and mass matrices. We present a gradient recovery method based on an oblique projection, where the gradient of the L2-polynomial projection of a solution is projected onto a virtual element space. This results in a computationally efficient numerical method. We present numerical results computing the gradients on different polygonal meshes to demonstrate the flexibility of the method.

Charts displayed on mobile devices was verified in comparison to standardized ETDRS charts. Such method of visual acuity assessment is characterized by stabile brightness and contrast. Moreover the ability to dynamically display random optotypes eliminates the problem of memorizing the contents of charts, making measurements more reliable. Our tests showed that the VA measured with mobile device and the VA tested using standardized printed charts are not significantly different. Full Text: PDF ReferencesB.

Abstract:
A study on the adsorption characteristic of Iron onto Poly[eugenol-co-(divinyl benzene)] (EDVB) from aqueous solution has been conducted. EDVB was produced and characterized by using FTIR spectroscopy. The adsorption was studied by a batch method by considering the factors affecting the adsorption such as initial metal ion concentration, adsorption selectivity, and mechanism of adsorption using a sequential desorption method. The adsorption of Iron onto EDVB followed a pseudo-2 order kinetics model with the rate constant of 0,144 L2 mmol-1 min-1. The adsorption isotherm was studied with Tempkin, Langmuir and Freundlich models. The adsorption capacity (Qmax) obtained by Langmuir isotherms was 250mg.L-1 while the equilibrium value was 0.8 Lmg-1. A competitive adsorption study showed that EDVB is adsorbed selectively towards Iron rather than Chromium, Coppers and Cadmium ions. The interaction type of Iron onto EDVB was determined by a sequential desorption.Keywords: Polyeugenol; divinyl benzene (DVB); adsorption; Iron; FeReferencesAbasi, C. Y.; Abia, A.A.; Igwe, J.C.

Abstract:
The impact of agricultural intensification on soil degradation now is occurring in tropical countries. The objective of this study was to determine the effect of long-term tillage and N fertilization on soil properties and crop yields in corn-soybean rotation. This long-term study which initiated since 1987 was carried out on a Typic Fragiudult soil at Politeknik Negeri Lampung, Sumatra (105o13’45.5"-105o13’48.0"E, 05o21’19.6"-05o21’19.7"S) in 2010 and 2011. A factorial experiment was arranged in a randomized block design with four replications. The first factor was tillage system namely intensive tillage (IT) and conservation tillage (CT) which consist of minimum tillage (MT) and no-tillage (NT); while the second factor was N fertilization with rates of 0, 100 and 200 kg N ha-1 applied for corn, and 0, 25, and 50 kg N ha-1 for soybean. The results showed that bulk density and soil strength at upper layer after 24 years of cropping were similar among treatments, but the soil strength under IT at 50-60 cm depth was 28.2% higher (p<0.05) than NT. Soil moisture and temperature under CT at 0-5 cm depth were respectively 38.1% and 4.5% higher (p<0.05) than IT. High N rate decreased soil pH at 0-20 cm depth as much as 10%, but increased total soil N at 0-5 cm depth as much as 19% (p<0.05). At 0-10 cm depth, MT with no N had highest exchangeable K, while IT with medium N rate had the lowest (p<0.05). At 0-5 cm depth, MT with no N had highest exchangeable Ca, but it had the lowest (p<0.05) if combined with higher N rate. Microbial biomass C throughout the growing season for NT was consistently highest and it was 14.4% higher (p<0.05) than IT. Compared to IT, Ap horizon of CT after 24 years of cropping was deeper, with larger soil structure and more abundance macro pores. Soybean and corn yields for long-term CT were 64.3% and 31.8% higher (p<0.05) than IT, respectively. Corn yield for long-term N with rate of 100 kg N ha-1 was 36.4% higher (p<0.05) than with no N.Keywords: Conservation tillage, crop yields, N fertilization, soil properties[How to Cite: Utomo M, IS Banuwa, H Buchari, Y Anggraini and Berthiria. 2013.Long-term Tillage and Nitrogen Fertilization Effects on Soil Properties and Crop Yields.

Abstract:
Sclerosant foam, a mixture of a surfactant liquid and air, is injected directly into varicose veins as a treatment that causes the vein to collapse. This investigation develops a model that will allow the medical specialist to visualise how the sclerosant foam will interact with the blood and behave within the vein. The process is simulated using a multiphase computational fluid dynamics model with the sclerosant foam considered as a two-phase non-Newtonian power law viscosity liquid. The governing multiphase equations are solved using an Eulerian⁠–⁠Eulerian approach coupled with a population balance model to predict the bubble size distribution within the flow field. The computational results demonstrate similar flow characteristics and flow features to an available set of experimental results. The model predicts the mixing layers between the sclerosant foam and the ambient fluid, and the sclerosant liquid and the ambient fluid, as well as the sclerosant liquid coverage on the vein wall and the bubble size distribution within the vein. These quantities are of interest to medical specialists allowing them to assess the treatment feasibility and safety before treating the patients. References S. Ali Mirjalili, J. C. Muirhead, and M.

Abstract:
The discrete thin plate spline smoother fits smooth surfaces to large data sets efficiently. It combines the favourable properties of the finite element surface fitting and thin plate splines. The efficiency of its finite element grid is improved by adaptive refinement, which adapts the precision of the solution. It reduces computational costs by refining only in sensitive regions, which are identified using error indicators. While many error indicators have been developed for the finite element method, they may not work for the discrete smoother. In this article we show three error indicators adapted from the finite element method for the discrete smoother. A numerical experiment is provided to evaluate their performance in producing efficient finite element grids. References F. L. Bookstein.

Abstract:
Accurate values for the six cardiac conductivities of the bidomain model are crucial for meaningful electrophysiological simulations of cardiac tissue and are yet to be achieved. A two-stage optimisation process is used to retrieve the cardiac conductivities from cardiac potentials measured on a multi-electrode array—the first stage simultaneously fits all six conductivities, and the second stage fits a subset of the conductivities (intracellular conductivities), while holding the remainder of the conductivities (extracellular conductivities) constant. Previous studies have shown that the intracellular conductivities are retrieved to a lesser degree of accuracy than extracellular conductivities. This study tests the proposition that there exists a relationship between the extracellular and intracellular conductivities during the second stage of the optimisation that affects the accuracy of the retrieved intracellular conductivities. A measure to quantify this relationship is developed using polynomial chaos. The results show that a significant relationship does exist, and thus any errors in the extracellular conductivities are magnified in the retrieved intracellular conductivities. Thus, it is suggested that future protocols for retrieving conductivities incorporate the uncertainty in the extracellular conductivities. References R. C. Aster, B. Borchers, and C. H. Thurber.

Abstract:
Liquid crystal on silicon (LCOS) spatial light modulator (SLM) is the most widely used optical engine for digital holography. This paper aims to provide an overview of the applications of phase-only LCOS in two-dimensional (2D) holography. It begins with a brief introduction to the holography theory along with its development trajectory, followed by the fundamental operating principle of phase-only LCOS SLMs. Hardware performance of LCOS SLMs (in terms of frame rate, phase linearity and flicker) and related experimental results are presented. Finally, potential improvements and applications are discussed for futuristic holographic displays. Full Text: PDF ReferencesM. Wolfke, Physikalische Zeitschrift 21, 495 (1920). DirectLink D.

Abstract:
This technical note summarizes a technical comparison of common testing procedures, as well as reviewed of the UN Test N` 5, for the assessment of the self-heating properties of cargoes and materials that has shown a clear trend on maritime fire and explosions events, as well as considering of external factors that can combine self-heating and emit flammable gases to conclude in an unlikely event affecting the security of crews and ships. A high understanding of the external factors effect on the cargo materials certainly will help the application of spontaneous reactions management actions (SRMA) on board of ships during the cargo sea passage. The intended comparison is based on laboratory, industry and field observations and data, whereas the among the external factors considered are, moisture content, stockpile procedure and aging, air velocities and moderate pressures internal and externally to the cargo material. The comparison results have shown that the self-heating and the flammable gas emissions has a common pattern when reacting with any oxygen available source, regardless the reactive material chemical composition.

Abstract:
The projection method was first introduced by Chorin [Bull. AMS 73 (1967), pp. 928–931] and Temam [Arch. Rat. Mech. Anal. 33 (1969), pp. 377–385] as a computationally efficient numerical method to solve the incompressible Navier–Stokes equations. Despite its success in decoupling the computations of velocity and pressure, it suffers from inaccurate numerical boundary layers. As an effort to resolve this inaccuracy, E and Liu [Int. J. Numer. Meth. Fluids 34 (2000), pp. 701–710] proposed the gauge method, which is a reformulation of the Navier–Stokes equations in terms of an auxiliary vector field and a gauge variable. This method utilizes the freedom of choosing a boundary condition for the gauge variable to reduce the numerical coupling between the considered variables. Nevertheless, the computational implementation of the boundary conditions for the auxiliary vector field is difficult in the context of finite elements since they involve either the normal or tangential derivative of the gauge variable. In order to circumvent this issue, we propose a weak formulation of the boundary conditions based on the symmetric Nitsche method. Computational results are presented to illustrate the accuracy of the proposed method. References J. H. Bramble, J. E. Pasciak, and A. T. Vassilev.

Abstract:
Bioclimatology is applied for growing tea in the West of Nghe An province, where the tea is considered as a high economic efficient plant to be priorly cultivated for reducing poverty and getting rich. Based on the bioclimatic characteristics of tea plant and regional climatic data from 1980 to 2014, the bioclimatic diagrams are built and the tea cultivability is mapped in term of annual average temperature and total precipitation, for this region with regarding its district of Con Cuong as an analytical key. The climate, including both temperature and precipitation, in Con Cuong is relatively suitable for the tea plantation. The Western Nghe An, a land of approx. 1.4 million ha, could be classified in five areas with different suitability for tea plant. The unfavorable area occupies only 1% of total region and the four favorable rests account for 99% of total, in which, the most favorable area is largest with about 746,355 ha, i.e. over 50% of whole region. The three other areas are cultivable but they are less favorable in terms of either temperature or precipitation. Growing tea in Western Nghe An, even in favorable areas, it should be taken into account of the weather disadvantages in certain moments of the year such as extreme dry, cold, hot and rainy events.ReferencesAhmed S., 2014.

Abstract:
The aim of this short review is to recall various designs of diffraction gratings when the condition of the period’s identity is relaxed and to mention resulting thus some of their applications. Among others the apodization function can be implemented as a variable diffraction efficiency due to the gradual change of the period’s shape. Another possible application is the passive achromatization of the diffraction efficiency of the blazed gratings by randomizing their blaze angle. Full Text: PDF ReferencesP. Jacquinot and B.

Abstract:
Abstract. This study proposed a new discharge estimation method using a mean velocity formula derived from Chiu's 2D velocity formula of probabilistic entropy concept and the river bed shear stress of channel. In particular, we could calculate the mean velocity, which is hardly measurable in flooding natural rivers, in consideration of several factors reflecting basic hydraulic characteristics such as river bed slope, wetted perimeter, width, and water level that are easily obtainable from rivers. In order to test the proposed method, we used highly reliable flow rate data measured in the field and published in SCI theses, estimated entropy M from the results of the mean velocity formula and, at the same time, calculated the maximum velocity. In particular, we obtained phi(M) expressing the overall equilibrium state of river through regression analysis between the maximum velocity and the mean velocity, and estimated the flow rate from the newly proposed mean velocity formula. The relation between estimated and measured discharge was analyzed through the discrepancy ratio, and the result showed that the estimate value was quite close to the measured data.

Abstract:
In March of 2013, new symptoms were observed in more than seven million nursery-grown sweet pepper (Capsicum annuum) plants in El Ejido, Almería (southern Spain). Symptoms included wilting without yellowing of leaves and stunting of plants. Plant crowns exhibited necrosis that advanced through the main root along with slight root rot. Xylem was not affected above or below the crown. Symptoms were thought to be caused by the well-known pepper pathogen Phytophthora capsici. However, sporodochia of Fusarium oxysporum were observed on plant crowns. Symptomatic seedlings (n = 200) were sampled and analyzed. Tissue from roots and epidermal crowns were plated on PDA, PARP, and Komada media, as well as stem discs on PDA and Komada. No Phytophthora sp. were observed and F. oxyporum was exclusively isolated from all 200 samples, from roots and crowns, but not from xylem. Pathogenicity of 60 of these F. oxysporum isolates was studied by inoculation onto sweet pepper plants (cv. del Piquillo) at the 2-true-leaf stage. Twelve plants per isolate, grown on autoclaved vermiculite, were inoculated by drenching with 20 ml of a conidial suspension (1 × 105 CFU/ml) of each isolate per plant. Each suspension was obtained by blending one PDA petri dish fully covered with one isolate. Non-inoculated plants served as control. Plants were maintained for 30 days in a growth chamber with a 14-h photoperiod (1.6 ×·104 lux) and temperatures at 23 to 26°C. The assay was conducted twice. Symptoms described above were reproduced on crown and roots of the inoculated plants with no symptoms in stem discs. No symptoms were observed on controls after 48 days. Host specificity was tested for 13 isolates to tomato (Solanum lycopersicum) cv. San Pedro, eggplant (S. melongena) cv. Alegria, cucumber (Cucumis sativus) cv. Marketmore, watermelon (Citrullus lanatus) cv. Sugar Baby, and Chinese cabbage (Brassica campestris subsp. condensa) cv. Kasumi (4). These plants were inoculated as previously described for pathogenicity tests (12 plants per species, repeated twice). None of the plants exhibited the characteristic symptoms after 60 days. Five isolates of F. oxysporum f. sp. radicis-cucumerinum and four isolates of F. o. f. sp radicis-lycopersici were also inoculated without any symptoms in any of the inoculated sweet pepper plants. Morphological identity of all isolates corresponded to F. oxysporum. The fungi were identified following the morphological keys and methodology provided by (1) and (2). Three isolates from the 60 tested were selected for molecular identification. Molecular identification was performed by sequencing partial TEF-1α gene (3). Subsequent database searches by BLASTn indicated that the resulting sequence of 659-bp had 100% identity with the corresponding gene sequence of F. oxysporum. The sequences were identical for the three isolates and were deposited on the EMBL Sequence Database (HG916993, HG916994, and HG916995). Results suggest that the pathogenic ability of the isolates varies from a vascular Fusarium wilt. F. oxysporum f. sp. capsici is a reported pathogen to sweet pepper (5), but the symptoms we have found are closer to those manifested by the formae speciales that causes root and crown rot of other plants. Consistent with the convention stablished for similar diseases we propose the name F. oxysporum f. sp. radicis-capsici f. sp. nov. References: (1) J. F. Leslie and B. A. Summerell.

Abstract:
Can Gio mangrove forest (CGM) is located downstream of Ho Chi Minh City (HCMC), situated between an estuarine system of Dong Nai - Sai Gon river and a part of Vam Co river. The CGM is the largest restored mangrove forest in Vietnam and the UNESCO’s Mangrove Biosphere Reserve. The CGM has been gradually facing to numeric challenges of global climate change, environmental degradation and socio-economic development for the last decades. To evaluate sediment quality in the CGM, we collected 13 cores to analyze for sediment grain size, organic matter content, and trace element concentration of Cd, Cr, Cu, Ni, Pb, Zn. Results showed that trace element concentrations ranged from uncontaminated (Cd, Cu, and Zn) to very minor contaminated (Cr, Ni, and Pb). The concentrations were gradually influenced by suspended particle size and the mangrove plants.ReferencesAnh M.T., Chi D.H., Vinh N.N., Loan T.T., Triet L.M., Slootenb K.B.-V., Tarradellas J., 2003.

Abstract:
This study was conducted to identify of rodent species and the ectoparasites are widely recognized for the type prevalent in homes, at Esna District, Luxor Governorate, Egypt, during 2020 year. The results were revealed that the presence of three species of rats included gray-bellied rat, Rattusrattusalexandrinusthe dominant species from, Rattusrattusfrugivorusand the Nile grass rat, Arvicanthisniloticus. The results also indicated that the identification of two types of fleas, Xenopsyllacheopis&Pulexirritans, and one species of lice, Polyplaxspinulosa, associated with the gray-bellied was identified. The study reports the interest in making integrated control programs for rodents to get rid of them and the risks of their external parasites. Introduction Rodents play an important role as hosts for ectoparasites and as repositories for various types of viruses, bacteria, rickets, protozoa, and parasitic worms that cause zoonotic diseases (Durden and Page, 1991; Azad and Beard, 1998; Coleman et al., 2003; Salibay and Claveria, 2005). Some examples of such diseases are rodent-borne hemorrhagic fever, plague, Lyme disease, leptospirosis, salmonellosis, murine typhus, scrub typhus, toxoplasmosis, shistosomiasis, nematodes and tapeworms. The close association between commensal rodents and humans and domestic animals is a risk factor for transmission of these diseases (Kia et al., 2009). The aim of this study is to identify rodent species spread with a study of external parasites of the most dominant species in houses of study area. Materials and methods • Study Area The present study was carried out to inventory of the types of rodent spread in houses with a study of external parasites of the most dominant species at Esna area, Luxor Governorate, Egypt, during 2020 year. • Identification of the different species of rodents Rodent species were collected from the aforementioned sites using 10 common wire traps. Each trap was stabbed with bread and distributed twice every 15 days at 6 PM. The next morning at 7 a.m., traps were examined, rodents identified and recorded for data processing. Captured rodents were graded and recorded (Desoky, 2011). • IdentificationRattusrattusalexandrinusectoparasites: Five rats were taken all Month during the study period, rodent were anesthetized in jar containing a cotton pad with chloroform and then brushed in a deep white plate using a relatively hard brush. After collection of the ectoparasites, they were preserved in plastic bags containing 70% ethyl alcohol and labeled with necessary information. The parasites were sorted and transferred to the microscope slide for identification. The ectoparasites were classified.(Soulsby, 1982&Meerburget al., 2009). Results and discussion The results showed in table 1 and figure 1 a survey of three types of rodents: It was also found that the gray-bellied rat is the most common species in the study area (Esna homes), because the gray-bellied rat is considered a household climbing rodentAbdel-Gawad (1974 and 2010). Table 1: survey of rodent species in houses at Esna area, Luxor Governorate, during 2020 year. Figure 1: Survey of rodent species in houses at Esna area, Luxor Governorate, during 2020 year. Data in table (2) the results showed that two types of fleas, Xenopsyllacheopis&Pulexirritans, and one lice, Polyplaxspinulosa, infested the captured Rattusrattusalexandrinus. Results similar withVatandoostet al. (2003) &Telmadarraiyet al. (2004) found that most medically important rodents belong to the families of Muridae and the Cricetidae. Rodents play a role in many diseases, such as plague, transmitted by the rat flea Xenopsyllacheopisand Weil's disease, a severe form of leptospirosis transmitted via infected rat urine, Dada (2016). The study showed that infecting rodents with external parasites, which have a serious importance in transmitting diseases to humans or animals, for example, the eastern mouse flea has been identified, which may be a carrier of the bacteria that causes plague. The transmission of these rat-borne parasites is exacerbated in societies where environmental and personal health standards are not maintained. From these results, an integrated control program for the gray bellied rat must be established inside the houses. Table 2: Types of external parasites identified onRattus r. alexandrinus Data in Table (3) and Figure (2) showed thatthe highest population density of rat ectoparasites was recorded during spring and summer months, followed by autumn, whereas the lowest density was recorded during winter months. Regardless of months, the results showed also, the highest average number of lice was in spring 18, followed by summer 15, followed by autumn 14, and the lowest of them was winter 4, where it was recorded. While the highest average number of fleas was in spring 5, followed by summer and winter 4, and the lowest of them were autumn 3. The results also showed that the numerical density of lice was higher than that of fleas on the body of a gray-bellied rat.Regardless of months, lice exhibited the highest population density, whereas, fleas showed the least population density, this may be attributed to that fleas visit rats for feeding only, but lice are permanent parasites on hosts. The results similar with Embarak (1997); Kia et al. (2009) &Desokyet al. (2010).

Figure 2: Seasonal numbers of ectoparasites for the gray-belliedrat at Esna area, Luxor Governorate, during 2020 year. Conclusion The results are useful in identifying the types of rodents and their external parasites that may transmit many diseases to humans or animals. It also helps in the future to increase the research study on this topic with attention to the participation of society as a whole to get rid of rodents and their external parasites.

Abstract:
The experiment was conducted in the Agronomy Field, Sher-e-Bangla Agricultural University (SAU), Dhaka-1207 during the period of November 17, 2016 to March 29, 2017 on growth and yield performance of selected wheat genotypes at variable irrigation. In this experiment, the treatment consisted of three varieties viz. V1 = BARI Gom 26, V2 = BARI Gom 28, V3 = BARI Gom 30, and four different irrigations viz. I0 = No Irrigation throughout the growing season, I1 = One irrigation (Irrigate at CRI stage), I2= Two irrigation (Irrigate at CRI and grain filling), I3= Three irrigation (irrigate at CRI, booting and grain filling stages). The experiment was laid out in two factors split plot with three replications. The collected data were statistically analyzed for evaluation of the treatment effect. Results showed that a significant variation among the treatments in respect majority of the observed parameters. Results showed significant variation in almost every parameter of treatments. The highest Plant height, number of effective tillers hill-1, spike length, number of grain spike-1 was obtained from BARI Gom-30. The highest grain weight hectare-1 (3.44 ton) was found from wheat variety BARI Gom-30. All parameters of wheat showed statistically significant variation due to variation of irrigation. The maximum value of growth, yield contributing characters, seed yield was observed with three irrigation (irrigate at CRI, booting and grain filling stages). The interaction between different levels of variety and irrigation was significantly influenced on almost all growth and yield contributing characters, seed yield. The highest yield (3.99 t ha-1) was obtained from BARI Gom-30 with three irrigation (irrigate at CRI, booting and grain filling stages). The optimum growth and higher yield of wheat cv. BARI Gom-30 could be obtained by applying three irrigations at CRI, booting and grain filling stages. Introduction Wheat (Triticumaestivum L.) is one of the most important cereal crops cultivated all over the world. Wheat production was increased from 585,691 thousand tons in 2000 to 713,183 thousand tons in 2013 which was ranked below rice and maize in case of production (FAO, 2015). In the developing world, need for wheat will be increased 60 % by 2050 (Rosegrant and Agcaoili, 2010). The International Food Policy Research Institute projections revealed that world demand for wheat will increase from 552 million tons in 1993 to 775 million tons by 2020 (Rosegrantet al.,1997). Wheat grain is the main staple food for about two third of the total population of the world. (Hanson et al., 1982). It supplies more nutrients compared with other food crops. Wheat grain is rich in food value containing 12% protein, 1.72% fat, 69.60% carbohydrate and 27.20% minerals (BARI, 2006). It is the second most important cereal crop after rice in Bangladesh. So, it is imperative to increase the production of wheat to meet the food requirement of vast population of Bangladesh that will secure food security. During 2013-14 the cultivated area of wheat was 429607 ha having a total production of 1302998 metric tons with an average yield of 3.033 metric tons ha-1whereas during 2012-13 the cultivated area of wheat was 416522 ha having a total production of 1254778 metric tons with an average yield of 3.013 tons ha-1 (BBS, 2014). Current demand of wheat in the country is 3.0-3.5 million tons. Increasing rate of consumption of wheat is 3% per year (BBS, 2013). Wheat production is about 1.0 milllion from 0.40 million hectares of land. Bangladesh has to import about 2.0-2.5-million-ton wheat every year. Wheat is grown all over Bangladesh but wheat grows more in Dhaka, Faridpur, Mymensingh, Rangpur, Dinajpur, Comilla districts. Wheat has the umpteen potentialities in yield among other crops grown in Bangladesh. However, yield per hectare of wheat in Bangladesh is lower than other wheat growing countries in the world due to various problems. Increasing food production of the country in the next 20 years to much population growth is a big challenge in Bangladesh. It is more difficult because, land area devoted to agriculture will decline and better-quality land and water resources will be divided to the other sector of national economy. In order to grow more food from marginal and good quality lands, the quality of natural resources like seed, water, varieties and fuel must be improved and sustained. Variety plays an important role in producing high yield of wheat because different varieties responded differently for their genotypic characters, input requirement, growth process and the prevailing environment during growing season. In Bangladesh the wheat growing season (November-March) is in the driest period of the year. Wheat yield was declined by 50% owing to soil moisture stress. Irrigation water should be applied in different critical stages of wheat for successful wheat production. Shoot dry weight, number of grains, grain yield, biological yield and harvest index decreased to a greater extent when water stress was imposed at the anthesis stage while water stress was imposed at booting stage caused a greater reduction in plant height and number of tillers (Gupta et al., 2001). Determination of accurate amount of water reduces irrigation cost as well as checks ground water waste. Water requirements vary depending on the stages of development. The pick requirement is at crown root initiation stage (CRI). In wheat, irrigation has been recommended at CRI, flowering and grain filling stages. However, the amount of irrigation water is shrinking day by day in Bangladesh which may be attributed to filling of pond river bottom. Moreover, global climate change scenarios are also responsible for their scarcity of irrigation water. So, it is essential to estimate water saving technique to have an economic estimate of irrigation water. Information on the amount of irrigation water as well as the precise sowing time of wheat with change in climate to expedite wheat production within the farmer’s limited resources is inadequate in Bangladesh. The need of water requirement also varies with sowing times as the soil moisture depletes with the days after sowing in Bangladesh as there is scanty rainfall after sowing season of wheat in general in the month of November. With above considerations, the present research work was conducted with the following objectives: To evaluate yield performance of selected wheat genotypes(s) at variable irrigation management. To identify the suitable genotype (s) of wheat giving higher yield under moisture stress condition. Materials and Methods Description of the experimental site The experiment was conducted in the Research Field, Sher-e-Bangla Agricultural University (SAU), Dhaka-1207 during the period of November, 2016 to March, 2017 to observe the growth and yield performance of selected wheat genotypes at variable irrigation management. The experimental field is located at 23041´ N latitude and 90º 22´ E longitude at a height of 8.6 m above the sea level belonging to the Agro-ecological Zone “AEZ-28” of Madhupur Tract (BBS, 2013). Soil characteristics The soil of the research field is slightly acidic in reaction with low organic matter content. The selected plot was above flood level and sufficient sunshine was available having available irrigation and drainage system during the experimental period. Soil samples from 0-15 cm depths were collected from experimental field. The experimental plot was also high land, having pH 5.56. Climate condition The experimental field was situated under sub-tropical climate; usually the rainfall is heavy during Kharifseason, (April to September) and scanty in Rabi season (October to March). In Rabi season temperature is generally low and there is plenty of sunshine. The temperature tends to increase from February as the season proceeds towards kharif. Rainfall was almost nil during the period from November 2016 to March 2017 and scanty from February to September. Planting material The test crop was wheat (Triticumaestivum). Three wheat varieties BARI Gom-26, BARI Gom-28 and BARI Gom-30 were used as test crop and were collected from Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur. Treatments The experiment consisted of two factors and those were the wheat genotypes and irrigation. Three wheat genotypes and four irrigations were used under the present study. Factor A: three wheat varieties- V1 = BARI Gom-26, V2 = BARI Gom-28 and V3= BARI Gom-30. Factor B: four irrigations- I0 = No Irrigation throughout the growing season, I1 = One irrigation (Irrigate at CRI stage), I2= Two irrigation (Irrigate at CRI and grain filling) and I3= Three irrigation (Irrigate at CRI, booting and grain filling stages). The experiment was laid out in a split plot design with three replications having irrigation application in the main plots, verities in the sub plots. There were 12 treatments combinations. The total numbers of unit plots were 36. The size of unit plot was 2 m x 2 m = 4.00 m2. The distances between sub-plot to sub-plot, main plot to main plot and replication to replication were, 0.75, 0.75 and 1.5 m, respectively. Statistical analysis The collected data on each plot were statistically analyzed to obtain the level of significance using the computer-based software MSTAT-C developed by Gomez and Gomez, 1984. Mean difference among the treatments were tested with the least significant difference (LSD) test at 5 % level of significance. Results and Discussion Plant height Plant height varied significantly among the tested three varieties (Table 1). At, 75 DAS, BARI Gom 30 showed the tallest plant height (34.72 cm) and BARI Gom 26 recorded the shortest plant height (32.32 cm). At, 90 DAS, BARI Gom 30 recorded the highest plant height (76.13 cm) was observed from BARI Gom 26. However, BARI Gom 26 recorded the shortest plant height (75.01 cm) which was also statistically similar with BARI Gom 28. Islam and Jahiruddin (2008) also concluded that plant height varied significantly due to various wheat varieties. Plant height of wheat showed statistically significant variation due to amount of irrigation at 75, 90 DAS under the present trial (Table 2). At 75 DAS, the tallest plant (34.78 cm) was recorded from I3 (Three irrigation) while the shortest plant (32.02 cm) was observed from I0 (No Irrigation throughout the growing season) treatment. At 60 DAS, the tallest plant (77.51 cm) was found from I3, which was statistically similar with I2 (Two irrigation) and I1 (One irrigation). The shortest plant (71.29 cm) was observed from I0. Plant height was likely increased due to applying higher amount of irrigation compared to less amount of irrigation. Sultana (2013) stated that increasing water stress declined the plant height. Interaction effect of variety and different amount of irrigation showed significant differences on plant height of wheat at 75 and 90 DAS (Table 3). The highest plant height at 30 was 38.00 cm obtained from V3I3 treatment combination. The shortest plant height at 30 was 30.67 cm obtained from V1I0 treatment combination. At 60 DAS, plant height was 78.50 cm obtained from V3I3 and lowest was 69.83 cm obtained from V1I0 treatment combination, which was statistically similar with V2I0 and 3I0 treatment combination. Table 1. Effect of variety on plant height of wheat at different days after sowing Table 2. Effect of irrigation on plant height of wheat at different days after sowing Table 3. Interaction effect of variety and irrigation on plant height of wheat Number of effective tiller hill-1 Number of effective tillers hill-1of wheat was not varied significantly due to varieties (Table 4). BARI Gom 30 produced the highest number of effective tillers hill-1 (9.33) and the lowest number of effective tillers hill-1(8.58) was observed in BARI Gom 26. Different levels of irrigation varied significantly in terms of number of effective tillers hill-1 of wheat at harvest under the present trial (Table 5). The highest number of effective tillers hill-1 9.89 was recorded from I3 treatment, while the corresponding lowest number of effective tillers hill-1 were 7.89 observed in I0 treatment. Sultana (2013) stated that increasing water stress reduced the number of tillers per hill. Variety and irrigation showed significant differences on number of effective tillers hill-1 of wheat due to interaction effect (Table 6). The highest number of effective tillers hill-1 10.33 were observed from V3I3 treatment combination, while the corresponding lowest number of effective tillers hill-1 as 7.33 were recorded from V1I0 treatment combination. Number of non-effective tiller hill-1 Number of non-effective tillers hill-1of wheat was not varied significantly due to varieties (Table 4). BARI Gom 26 produced the highest number of non-effective tillers hill-1 (1.33) and the lowest number of non-effective tillers hill-1(1.00) was observed in BARI Gom 30. Different levels of irrigation varied significantly in terms of number of non-effective tillers hill-1 of wheat at harvest under the present trial (Table 5). The highest number of non-effective tillers hill-1 (2.00) was recorded from I0, while the corresponding lowest number of non-effective tillers hill-1 (0.67) was observed in I3. Variety and irrigation showed significant differences on number of non-effective tillers hill-1 of wheat due to interaction effect (Table 6). The highest number of non-effective tillers hill-1 (2.33) were observed from V1I0 treatment combination, while the corresponding lowest number of non-effective tillers hill-1 (0.33) were recorded from V3I2 treatment combination. Table 4. Effect of variety on yield and yield contributing characters of wheat Table 5. Effect of irrigation on yield and yield contributing characters of wheat Table 6. Interaction effect of variety and irrigation on yield and yield contributing characters of wheat Spike length (cm) Insignificant variation was observed on spike length (cm) at applied three types of modern wheat variety as BARI Gom-26 (V1), BARI Gom-28 (V2), and BARI Gom-30 (V3). From the experiment with that three types of varieties BARI Gom-30 (V3) (8.46 cm) given the largest spike length and BARI Gom-26 (V1) (8.08 cm) was given the lowest spike length (Table 4). Similar result was found using with different type varieties by Hefniet al. (2000). Different irrigation application has a statistically significant variation on spike length as irrigated condition (I3) was given the maximum result (9.17 cm) and non-irrigated condition (I0) given the lowest spike length (7.17 cm) (Table 5). Interaction effect of improved wheat variety and irrigation showed significant differences on spike length. Results showed that the highest spike length was obtained from V3I3 (10.33 cm). On the other hand, the lowest spike length was observed at V1I0 (6.50cm) treatment combination (Table 6). Grain spike-1 Significant variation was observed on grain spike-1 at these applied three types of modern wheat variety. The BARI Gom-30 (V3) (37.75) given the maximum number of grain spike-1 and BARI Gom-26 (V1) (36.92) was given the lowest number of grain spike-1, which was statistically similar with V2 treatment (Table 4). Different wheat genotypes have significant effect on grain spike-1 observed also by Rahman et al. (2009). Different irrigation application has a statistically significant variation on grain spike-1 as the irrigation condition (I3) was given the maximum result (39.33), which was statistically similar with I2 and non-irrigated condition (I0) given the lowest grain spike-1 (34.56) (Table 5). Sarkar et al. (2010) also observed that irrigation have a significant effect on grain spike-1. Interaction effect of improved wheat variety and irrigation showed significant differences on grain spike-1. Results showed that the highest grain spike-1 was obtained from V3I3 (41.0). On the other hand, the lowest grain spike-1 was observed at V1Io (34.00) which were also statistically similar with V3Io (34.67) (Table 6). 3Thousand Seed weight There was significant variation was observed on thousand seed weight due to different types of modern wheat variety. The wheat variety of BARI Gom-30 (V3) (50.40 g) given the maximum thousand seed weight and statistically different from BARI Gom-28 (V2) (46.74 g). BARI Gom-26 (V1) (46.22 g) was given the lowest thousand seed weight (Table 7). Rahman et al. (2009), Islam et al. (2015) also conducted experiment with different variety and observed have effect of varieties on yield. Different irrigation application has a statistically significant variation on thousand seed weight. The I3 was given the maximum thousand seed weight (48.91) and non-irrigated condition (I0) given the lowest yield (46.13 g) (Table 8). Sarkar et al. (2010), Baser et al. (2004) reported that grain yield under non-irrigated conditions was reduced by approximately 40%. Bazzaet al. (1999) reported that one water application during the tillering stage allowed the yield to be lower only than that of the treatment with three irrigations but Meenaet al. (1998) reported that wheat grain yield was the highest with 2 irrigations (2.57 ton/ha in 1993 and 2.64 ton/ha) at flowering and/or crown root initiation stages. Wheat is sown in November to ensure optimal crop growth and avoid high temperature and after that if wheat is sown in the field it faces high range of temperature for its growth and development as well as yield potential.

(2015) reported that late planted wheat plants faced a period of high temperature stress during reproductive stages causing reduced kernel number spike-1 as well as the reduction of grain yield. Interaction effect of improved wheat variety and irrigation showed significant differences on thousand seed weight (Table 9). Results showed that the highest thousand seed weight (52.33 g) was obtained from V3I3 which was statistically similar with V3I2 (52.06 g). On the other hand, the lowest yield (45.36 g) was observed at V1I1. Table 7. Effect of variety on yield and yield of wheat Table 8. Effect of irrigation on yield and yield of wheat Table 9. Interaction effect of variety and irrigation on yield and yield of wheat Grain yield (t ha-1) Different wheat varieties showed significant difference for grain weight hectare-1 (Table 7). The highest grain yield hectare-1 (3.44 ton) was found from wheat variety BARI Gom-30 (V3), which was statistically similar with V2, whereas the lowest (3.21 ton) was observed from wheat variety BARI gom 26. Rahman et al. (2009), Islam et al. (2015) also conducted experiment with different variety and observed have effect of varieties on yield. Significant difference was observed for yield for different irrigation application. The three irrigation (I3) was given the maximum yield (3.74 t ha-1), which was statistically similar with I2 treatment and non-irrigated condition (I0) given the lowest yield (2.97 t ha-1) (Table 8). Sarkar et al. (2010), Baser et al. (2004) reported that grain yield under non-irrigated conditions was reduced by approximately 40%. Bazzaet al. (1999) reported that one water application during the tillering stage allowed the yield to be lower only than that of the treatment with three irrigations but Meenaet al. (1998) reported that wheat grain yield was the highest with 2 irrigations (2.57 ton/ha in 1993 and 2.64 ton/ha) at flowering and/or crown root initiation stages. Wheat is sown in November to ensure optimal crop growth and avoid high temperature and after that if wheat is sown in the field it faces high range of temperature for its growth and development as well as yield potential. Islam et al. (2015) reported that late planted wheat plants faced a period of high temperature stress during reproductive stages causing reduced kernel number spike-1 as well as the reduction of grain yield. Interaction effect of improved wheat variety and irrigation showed significant differences on yield (t ha-1). Results showed that the highest yield (3.99 t ha-1) was obtained from V3I3, which was statistically similar with V2I3 and V3I2. On the other hand, the lowest yield (2.93 t ha-1) was observed at V1I0 (Table 7). Straw yield (t ha-1) Applied three types of wheat variety have a statistically significant variation on straw yield (t ha-1). The maximum straw yield (1.95 t ha-1) was obtained from BARI Gom-30 and BARI Gom-26 (V1) was given the lowest straw yield (1.87 t ha-1), which was statistically similar with V2 treatment. Different irrigation application has a statistically significant variation on straw yield (t ha-1) of wheat. The I3 treatment for straw yield (2.01 t ha-1) was given the maximum result and non-irrigated condition (I0) given the lowest (1.80 t ha-1). Similar results were found by Ali and Amin (2004) through his experiment. Interaction effect of improved wheat variety and irrigation showed significant differences on straw yield (t ha-1). The highest straw yield (2.08 t ha-1) was obtained from V3I3 which was statistically similar with V3I2 (2.07 t ha-1) treatment combination. On the other hand, the lowest straw yield (1.78 t ha-1) was observed at V1Io, which was statistically similar with V2I0 (2.07 t ha-1) treatment combination. Biological yield Significant variation was attained for biological yield for different wheat varieties. The variety BARI Gom-30 given the maximum biological yield (5.39 t ha-1) and BARI Gom-26 (V1) was given the lowest biological yield (5.078 t ha-1). Different irrigation application has a statistically significant variation biological yield (t ha-1) of wheat. The I3 treatment for biological yield (5.76 t ha-1) was given the maximum result and non-irrigated condition (I0) given the lowest (4.77 t ha-1). Similar results were found by Ali and Amin (2004) through his experiment. At the time of biological yield (t ha-1) consideration with variety and irrigation statistically significance variation was observed as maximum biological yield (t ha-1) at V3I3 (6.07 t ha-1). On the other hand, the lowest result was given at V1Io (4.72 tha-1). Summary And Conclusion It may be concluded within the scope and limitation of the present study that the optimum growth and higher yield of wheat cv. BARI Gom-30 could be obtained by applying three irrigations at irrigate at CRI, booting and grain filling stages. However, further studies are necessary to arrive at a definite conclusion.

Abstract:
The article presents selected concepts, models and theories of safety known from research and applications in various areas of technology and suitable for use in the field of transport. In particular, attention was paid to cognitively promising in the field of transport safety, and relatively little used research concepts here: Normal Accident Theory (NAT) Ch.Perrow, "Swiss cheese model" /SCh-M/ by J. Reason, concepts of "safe space of action" by J. Rasmussen and R. Amalberti, the concept of High Reliability Organizations /HRO/, or even interpretations of the transport system as a complex system (CS). The main aim of the article was to present some important general safety concepts and show that they can be used to model safety in the field of transport. The article shows that the so-called Geysen's thesis allows for the development of justified safety analogies between transport systems and such systems of technology that have greater scientific and engineering achievements in the field of safety.

Abstract:
The crystal structures of the compounds SBr3AsF6 (1), SeI3AsF6 (2), SeI3SbF6 (3), and TeI3SbF6 (4) are reported and the quantitative preparation of the hitherto unknown 3 and 4 from SbF5 and the respective elements in SO2 are given. Crystal data are as follows: 1, monoclinic, space group P21/c, with a = 8.015(1) Å, b = 9.342(1) Å, c = 12.126(2), β = 97.81(1)°, and Z = 4; 2, monoclinic, space group P21/c, with a = 8.380(2) Å, b = 10.237(1) Å, c = 12.524(1) Å, β = 99.36(1)°, and Z = 4; 3, monoclinic, space group P21/c, with a = 8.548(2) Å, b = 10.297(6) Å, c = 12.877(8) Å, β = 98.70(3)°, and Z = 4; 4, monoclinic, space group P21/c, with a = 8.463(1) Å, b = 10.676(2) Å, c = 13.121(4) Å, β = 100.05(1), and Z = 4. Compounds 1, 2, 3, and 4 are isostructural and were refined to a final R values of 0.040, 0.051, 0.047, and 0.037, respectively. The structures of these salts consist of essentially discrete MX3+ cations and M′F6− anions (M = S, Se, Te; X = Br, I; M′ = As, Sb) with some cation–anion interactions. TheSeI3+ bond distances and angles were essentially identical in both AsF6− and SbF6− salts (average Se—I distance and I—Se—I angle for AsF6− salt; 2.508(2) Å, 102.4(1)° and for SbF6− salt; 2.512(1) Å, 102.3(1)°). Similarly the average Te—I bond distance and I—Te—I angle for TeI3SbF6 were 2.666(1) Å and 99.8(1)° which are essentially identical to those in the previously reported TeI3AsF6. The average S—Br distance and Br—S—Br angle were 2.142(6) Å and 103.4(2)° in SBr3AsF6. Estimates of the S—I bond distance and I—S—I bond angle in the as yet unknown SI3M′F6 are made from the extrapolation of MX3+ data. The bond distances observed in the simple MX3+ cations (M = S, Se, Te; X = Cl, Br, I) with anions of very low basicity are within 0.02 Å of the corresponding distances calculated by the Schomaker–Stevenson equation. The observed and estimated bond distances in SBr3+, SI3+, and SeI3+ are significantly longer than the corresponding S—Br, S—I, and Se—I distances in S7I+, S7Br+, and Se6I22+. This observation is used to support the thesis that the long intra-cationic halogen–chalcogen contacts in polychalcogen–halogen cations are weakly bonding, and responsible for the cluster-like nature of these cations. The heats of formation of 1 and 2 from their respective elements and AsF5 were estimated.

Abstract:
Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, coastal salt-marches and wetlands. This paper provides a summary of the current state of knowledge of sea level-rise and its effects on both human and natural ecosystems. The focus is on coastal urban areas and low lying deltas in South-East Asia and Vietnam, as one of the most threatened areas in the world. About 3 mm per year reflects the growing consensus on the average SLR worldwide. The trend speeds up during recent decades. The figures are subject to local, temporal and methodological variation. In Vietnam the average values of 3.3 mm per year during the 1993-2014 period are above the worldwide average. Although a basic conceptual understanding exists that the increasing global frequency of the strongest tropical cyclones is related with the increasing temperature and SLR, this relationship is insufficiently understood. Moreover the precise, complex environmental, economic, social, and health impacts are currently unclear. SLR, storms and changing precipitation patterns increase flood risks, in particular in urban areas. Part of the current scientific debate is on how urban agglomeration can be made more resilient to flood risks. Where originally mainly technical interventions dominated this discussion, it becomes increasingly clear that proactive special planning, flood defense, flood risk mitigation, flood preparation, and flood recovery are important, but costly instruments. Next to the main focus on SLR and its effects on resilience, the paper reviews main SLR associated impacts: Floods and inundation, salinization, shoreline change, and effects on mangroves and wetlands. The hazards of SLR related floods increase fastest in urban areas. This is related with both the increasing surface major cities are expected to occupy during the decades to come and the increasing coastal population. In particular Asia and its megacities in the southern part of the continent are increasingly at risk. The discussion points to complexity, inter-disciplinarity, and the related uncertainty, as core characteristics. An integrated combination of mitigation, adaptation and resilience measures is currently considered as the most indicated way to resist SLR today and in the near future.References Aerts J.C.J.H., Hassan A., Savenije H.H.G., Khan M.F., 2000.

Abstract:
AbstractThis thesis is concerned with the expansions of algebraic structures and their fit in Shelah’s classification landscape.The first part deals with the expansion of a theory by a random predicate for a substructure model of a reduct of the theory. Let T be a theory in a language $\mathcal {L}$ . Let $T_0$ be a reduct of T. Let $\mathcal {L}_S = \mathcal {L}\cup \{S\}$ , for S a new unary predicate symbol, and $T_S$ be the $\mathcal {L}_S$ -theory that axiomatises the following structures: $(\mathscr {M},\mathscr {M}_0)$ consist of a model $\mathscr {M}$ of T and S is a predicate for a model $\mathscr {M}_0$ of $T_0$ which is a substructure of $\mathscr {M}$ . We present a setting for the existence of a model-companion $TS$ of $T_S$ . As a consequence, we obtain the existence of the model-companion of the following theories, for $p>0$ a prime number: • $\mathrm {ACF}_p$ , $\mathrm {SCF}_{e,p}$ , $\mathrm {Psf}_p$ , $\mathrm {ACFA}_p$ , $\mathrm {ACVF}_{p,p}$ in appropriate languages expanded by arbitrarily many predicates for additive subgroups;• $\mathrm {ACF}_p$ , $\mathrm {ACF}_0$ in the language of rings expanded by a single predicate for a multiplicative subgroup;• $\mathrm {PAC}_p$ -fields, in an appropriate language expanded by arbitrarily many predicates for additive subgroups.From an independence relation in T, we define independence relations in $TS$ and identify which properties of are transferred to those new independence relations in $TS$ , and under which conditions. This allows us to exhibit hypotheses under which the expansion from T to $TS$ preserves $\mathrm {NSOP}_{1}$ , simplicity, or stability. In particular, under some technical hypothesis on T, we may draw the following picture (the left column implies the right column): Configuration $T_0\subseteq T$ Generic expansion $TS$ $T_0 = T$ Preserves stability $T_0\subseteq T$ Preserves $\mathrm {NSOP}_{1}$ $T_0 = \emptyset $ Preserves simplicityIn particular, this construction produces new examples of $\mathrm {NSOP}_{1}$ not simple theories, and we study in depth a particular example: the expansion of an algebraically closed field of positive characteristic by a generic additive subgroup. We give a full description of imaginaries, forking, and Kim-forking in this example.The second part studies expansions of the group of integers by p-adic valuations. We prove quantifier elimination in a natural language and compute the dp-rank of these expansions: it equals the number of independent p-adic valuations considered. Thus, the expansion of the integers by one p-adic valuation is a new dp-minimal expansion of the group of integers. Finally, we prove that the latter expansion does not admit intermediate structures: any definable set in the expansion is either definable in the group structure or is able to “reconstruct” the valuation using only the group operation.Abstract prepared by Christian d’Elbée.E-mail: delbee@math.univ-lyon1.frURL: https://choum.net/~chris/page_perso

Abstract:
The general framework of this paper is in the field of numerical simulation of asperity crushing. Different material forming processes, such as strip-rolling and deep drawing, imply mixed lubrication. In this lubrication regime, two types of contact are present at the same time: a direct contact between the two solids at the asperity level and also valleys filled with pressurized oil. Theses contact conditions have a large influence on friction and wear taking place during the upsetting process. As this mixed type of contact is not yet fully understood from the physics point of view, numerical models are essential to achieve a better understanding. For example, semi-analytical asperity crushing models have been developed by Wilson&Sheu [1] and Sutcliffe [2] to take into account the influence of bulk plastic deformations on asperity crushing. The finite element method has also been used to model asperity crushing. Ike&Makinouchi [3] studied the behavior of 2D triangular-shaped asperities under different boundary conditions. Krozekwa et al. [4] modeled 3D triangular asperities behavior, for various bulk strain directions. More recently, Lu et al. [5] compared experimental results of pyramid-shaped asperity and ridge-shaped asperity crushing with finite element simulation results. As in the three former references mentioned above, it has been decided, to study the interaction between a rigid plane and a simplified geometry asperity without lubricant. In this article, numerical asperity crushing results obtained with Metafor[6], a home made large strains software, will be presented. Those results will illustrate the influence of boundary conditions, contact pressure, large bulk strain and geometry of asperities on the evolution of the contact area. As the asperity crushing behaviour is known to be very sensitive to the boundary conditions, in this article, we will also present results using boundary conditions from a cold rolling model named MetaLub. MetaLub [7-8] is a software developed at the University of Liege in partnership with ArcelorMittal R&D center. It iteratively solves the equations resulting from the discretisation using the slab method of the strip coupled to a mixed lubrication model at the interface. This lubrication model takes into account the evolution of the oil film thickness as well as the asperity crushing along the roll bite. We will compare the evolution of the relative contact area obtained with MetaLub to the results obtained with finite elements simulations using the same boundary conditions.

Abstract:
Aligning protein-protein interaction networks from different species is a useful mechanism for figuring out orthologous proteins, predicting/verifying protein unknown functions or constructing evolutionary relationships. The network alignment problem is proved to be NP-hard, requiring exponential-time algorithms, which is not feasible for the fast growth of biological data. In this paper, we present a novel protein-protein interaction global network alignment algorithm, which is enhanced with an extended large neighborhood search heuristics. Evaluated on benchmark datasets of yeast, fly, human and worm, the proposed algorithm outperforms state-of-the-art. Furthermore, the complexity of ours is polynomial, thus being scalable to large biological networks in practice.

Abstract:
We consider a local projection stabilisation based on biorthogonal systems and adaptive refinement for convection-diffusion-reaction differential equations. The local projection stabilisation and adaptive finite element method are both based on a biorthogonal system. We investigate the numerical efficiency of the approach when compared to the standard finite element method. Numerical examples are presented to demonstrate the performance of the approach.

(Symmetry Cult Sci 22(3–4):435–459, 2011) our computer program (Prok in Period Polytech Ser Mech Eng 36(3–4):299–316, 1992) found 5079 equivariance classes for combinatorial face pairings of the double-simplex. From this list we have chosen those 7 classes which can form charts for hyperbolic manifolds by double-simplices with ideal vertices. In such a way we have obtained the orientable manifold of Thurston (The geometry and topology of 3-manifolds (Lecture notes), Princeton University, Princeton, 1978), that of Fomenko–Matveev–Weeks (Fomenko and Matveev in Uspehi Mat Nauk 43:5–22, 1988; Weeks in Hyperbolic structures on three-manifolds. Ph.D. dissertation, Princeton, 1985) and a nonorientable manifold $$M_{c^2}$$ M c 2 with double simplex $${\widetilde{{\mathcal {D}}}}_1$$ D ~ 1 , seemingly known by Adams (J Lond Math Soc (2) 38:555–565, 1988), Adams and Sherman (Discret Comput Geom 6:135–153, 1991), Francis (Three-manifolds obtainable from two and three tetrahedra. Master Thesis, William College, 1987) as a 2-cusped one. This last one is represented for us in 5 non-equivariant double-simplex pairings. In this paper we are going to determine the possible Dehn type surgeries of $$M_{c^2}={\widetilde{{\mathcal {D}}}}_1$$ M c 2 = D ~ 1 , leading to compact hyperbolic cone manifolds and multiple tilings, especially orbifolds (simple tilings) with new fundamental domain to $${\widetilde{{\mathcal {D}}}}_1$$ D ~ 1 . Except the starting regular ideal double simplex, we do not get further surgery manifold. We compute volumes for starting examples and limit cases by Lobachevsky method. Our procedure will be illustrated by surgeries of the simpler analogue, the Gieseking manifold (1912) on the base of our previous work (Molnár et al. in Publ Math Debr, 2020), leading to new compact cone manifolds and orbifolds as well. Our new graphic analysis and tables inform you about more details. This paper is partly a survey discussing as new results on Gieseking manifold and on $$M_{c^2}$$ M c 2 as well, their cone manifolds and orbifolds which were partly published in Molnár et al. (Novi Sad J Math 29(3):187–197, 1999) and Molnár et al.

Abstract:
Wheat (Triticum aestivum L.) stem rust caused by Puccinia graminis f. sp. tritici (Pgt) was generally insignificant in Europe from the 1960s until 2016, where a new race (TTRTF) caused damage on huge areas of durum wheat and bread wheat in Sicily (Bhattacharya, 2017). During the following five years, TTRTF was detected in eight additional countries in south- and central Europe (Patpour et al. 2022). In July 2021, seven wheat stem rust samples collected from spring wheat and one from barley in Svalov (55° 54′ 10.8″ N, 13° 6′ 54″ E) and Alnarp (55° 39′ 39.6″ N, 13° 4′ 40.8″ E), Sweden. Both cereal fields had a total disease incidence of 50% or higher. The samples were sent to the Global Rust Reference Center (GRRC, Denmark). Urediniospores of each sample were recovered on two susceptible cultivars, Line E and Morocco, which were used as susceptible controls in all experiments. Single pustular isolates were extracted and race typing was generally repeated two to three times based on Patpour et al. (2022) using 20 North American stem rust differential lines. Seedling infection types (IT) were scored on the first and second leaf 17 days post-inoculation using a 0–4 scale (Stakman et al. 1962; McIntosh et al. 1995). Isolates conferring ‘low’ ITs (i.e., 0, 0; 1, 1+, 2, and 2+), or combinations thereof, were considered ‘avirulent’ (incompatible), whereas ITs of 3-, 3, 3+, and 4 were considered ‘high’ (i.e., compatible, ‘virulent’). Race nomenclature was based on a modified letter code proposed by Jin et al. (2008). We conducted DNA extraction and molecular genotyping using seventeen Simple Sequence Repeat (SSR) primer pairs derived from Stoxen (2012) and applied at large scale by Patpour et al. (2022). Based on the results from pathotyping and genotyping, two samples from wheat showed Pgt race TKTTF (Clade IV-B), three from wheat TKKTF (Clade IV- F), and three samples from wheat and barley were identified as TTRTF (Clade III-B). This is the first report of race TTRTF in northern Europe, particularly, Sweden, which significantly extends the known distribution of this race. The TTRTF race is a serious threat to wheat productivity and evaluation of resistance of commercial European wheat varieties to the TTRTF race confirmed that 70% of the cultivars were susceptible (Patpour et al. 2022). Therefore, if the conditions are suitable for the establishment and development of stem rust, the disease can cause significant damage to the wheat crop in these countries. Susceptibility of European wheat varieties stress an urgent need to initiate new breeding efforts to identify effective sources of resistance to wheat stem rust in breeding programs.

Therefore, the problem of rational use of natural resources, in particular protection of early spring plant species is very important. However, literary sources analysis only reveals data on the biology of species of this genus. The present research,conducted in the spring of 2017-2019, focuses on anatomical and morphological features of two Altai species: Gagealutea and Gagea minima; these features were studied, clarified and confirmed by drawings and photographs. The anatomical structure of the stem and leaf blade was studied in detail. The obtained research results will prove useful for studies of medicinal raw materials and honey plants. The aforementioned species are similar in morphological features, yet G. minima issmaller in size, and its shoots appear earlier than those of other species Keywords: Flora,gageas,Altai species,vegetative organs., Refference: I.

Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Shulunova,Alexander I.Sidelnikov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00045 Abstract: Purpose.To determine the quantitative echogenicity indicators (and their ratio) of the layers of stomach and small intestine wall in healthy dogs. Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values ​​of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values ​​characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

Datieva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00046 Abstract: The aim of this work was to assess the functional reserves of the body to quantify individual health; adaptation, psychophysiological characteristics of the health quality of medical students in different seasons of the year. When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
