Abstract:
AbstractWe report the discovery of the longest known radio pulsar period. PSR J2144–3933, previously thought to have a period of 2.84 s, actually has a period of 8.51 s. Under the usual assumptions about the stellar equation of state, this pulsar has an average surface dipolar magnetic field strength of ~ 2.0 × 1012G. According to popular theories of the emission mechanism this pulsar should not be emitting radio waves because its long period and magnetic field strength make pair creation impossible for all reasonable magnetic field configurations. Either assumptions about the equation of state are incorrect, or the emission theories must be revised.

Abstract:
A 3-year field experiment was conducted at the Punjab Agricultural University, Ludhiana, during the rainy sea- son of ( kharif) 2006 to 2008, to study response of soybean [ Glycine max (L.) Merrill] to different levels of sulphur and born. The experiment comprised of 13 treatments including all the combinations of 4 sulphur (S) levels (10, 20, 30 and 40 kg/ha) and 3 boron (B) levels (0.5, 1.0 and 1.5 kg/ha) and absolute control (no S; no B). The highest grain yield, protein, oil content, gross and net returns of soybean were recorded with 40 kg S/ha, which were sta- tistically at par with 30 kg S/ha but significantly higher than other levels of sulphur. The productivity in 40 kg S/ha was enhanced 61.9% over the absolute control. The boron level of 1.5 kg/ha recorded the highest grain yield, gross and net returns, being statistically at par with 1.0 kg B/ha but significantly higher than 0.5 kg B/ha. The high- est S and B uptake were recorded in 40 kg S/ha and 1.5 kg B/ha respectively. The highest grain yield recorded in 40 kg S/ha and 1.5 kg B/ha was statistically at par with 40 kg S/ha and 1.0 kg B/ha, 30 kg S/ha and 1.0 kg B/ha, 20 kg S/ha and 1.5 kg B/ha and 30 kg S/ha and 1.5 kg B/ha treatments but was significantly higher than all the other combinations of sulphur and boron.

Abstract:
A field experiment was conducted at New Delhi during 2003 and 2005 on sandy loam soil with 14.35 kg/ha available S to evaluate the relative efficiency of sulphur (S) sources and rates in pigeon pea [ Cajanus cajan (L.) Millsp.]wheat [ Triticum aestivum (L.) emend. Fiori & Paol.] cropping system. The study revealed that application of 30 kg S/ha being at par with 60 kg/ha produced 24.9 and 0.62 more pods/plant and seeds /pod respectively than control (no S). This increase in yield attributes finally led to 0.47 t/ha higher pigeon pea yield over no S ap- plication (1.15 t/ha). S applied to pigeon pea at 60 kg/ha left behind 1.19 kg/ha more S in soil than 30 kg/ha, which resulted in higher grain yield of succeeding wheat by 0.58 tonne/ha. Among the S sources, cosavet being on par with gypsum gave 14.8% (0.23 t/ha) more grain yield of pigeon pea over elemental S (1.55 t/ha). Both these sources also proved superior in their residual effect on succeeding wheat when compared with elemental S. Wheat responded to direct application of 30 kg S/ha only. Cosavet was the best source from productivity point of view. However, application of 30 kg S/ha to pigeon pea as gypsum and to wheat as elemental S was promis- ing in terms of S efficiency and economics.

Abstract:
Low prices have prompted growers to contemplate transitioning to an organic system. We evaluated red clover-maize-soybean-wheat (Cl-M-S-W), maize-soybean (M-S-M-S), and soybean-wheat/red clover-maize-soybean (S-W/Cl-M-S) rotations in organic and conventional systems in New York, USA from 2015 to 2018 to identify profitable organic practices. Organic compared with conventional maize in 2017 had 14.6% higher yield and $2107/ha higher returns above selected costs in the S-W/Cl-M-S rotation; and had $1007/ha higher returns in the M-S-M-S rotation, despite 3.6% lower yield and higher production costs, because of the organic price premium. Likewise, organic compared with conventional soybean had ~$800 to ~$900/ha higher returns in 2017 and 2018, despite ~10% lower yield and ~$50/ha higher production costs, because of the organic price premium. Organic compared with conventional wheat yielded ~4% higher with $125/ha higher returns, despite ~$435/ha higher production costs. Organic compared with the conventional system had $1018/ha higher returns in the Cl-M-S-W rotation, $1782/ha higher in the M-S-M-S rotation, and $2961/ha higher in the S-W/Cl-M-S rotation in 2017 and 2018. Although returns in 2015 and 2016 (no organic premium) were lower, the organic compared with the conventional system from 2015 to 2018 had $673/ha higher returns in the Cl-M-S-W rotation, $497/ha higher in the M-S-M-S rotation, and $2355/ha higher in the S-W/Cl-M-S rotation indicating that the S-W/Cl-M-S rotation was the most profitable organic rotation during the four-year period.

Abstract:
A novel biomedical material composed of spherical hydroxyapatite (s-HA) and polyamide 66 (PA) biocomposite (s-HA/PA) was prepared, and its composition, mechanical properties, and cytocompatibility were characterized and evaluated. The results showed that HA distributed uniformly in the s-HA/PA matrix. Strong molecule interactions and chemical bonds were presented between the s-HA and PA in the composites confirmed by IR and XRD. The composite had excellent compressive strength in the range between 95 and 132 MPa, close to that of natural bone.In vitroexperiments showed the s-HA/PA composite could improve cell growth, proliferation, and differentiation. Therefore, the developed s-HA/PA composites in this study might be used for tissue engineering and bone repair.

Abstract:
AbstractField and greenhouse studies were conducted in 2016 and 2017 to determine sweetpotato tolerance to herbicides applied to plant propagation beds. Herbicide treatments included PRE application of flumioxazin (107 g ai ha−1), S-metolachlor (800 g ai ha−1), fomesafen (280 g ai ha−1), flumioxazin plus S-metolachlor (107 g ai ha−1 + 800 g ai ha−1), fomesafen plus S-metolachlor (280 g ai ha−1 + 800 g ai ha−1), fluridone (1,120 or 2,240 g ai ha−1), fluridone plus S-metolachlor (1,120 g ai ha−1 + 800 g ai ha−1), napropamide (1,120 g ai ha−1), clomazone (420 g ai ha−1), linuron (560 g ai ha−1), linuron plus S-metolachlor (560 g ai ha−1 + 800 g ai ha−1), bicyclopyrone (38 or 49.7 g ai ha−1), pyroxasulfone (149 g ai ha−1), pre-mix of flumioxazin plus pyroxasulfone (81.8 g ai ha−1 + 104.2 g ai ha−1), or metribuzin (294 g ai ha−1). Paraquat plus non-ionic surfactant (280 g ai ha−1 + 0.25% v/v) POST was also included. After plants in the propagation bed were cut and sweetpotato slip number, length, and weight had been determined, the slips were then transplanted to containers and placed either in the greenhouse or on an outdoor pad to determine any effects from the herbicide treatments on initial sweetpotato growth. Sweetpotato slip number, length, and/or weight were affected by flumioxazin with or without S-metolachlor, S-metolachlor with or without fomesafen, clomazone, and all fluridone treatments. In the greenhouse studies, initial root growth of plants after transplanting was inhibited by fluridone (1,120 g ai ha−1) and fluridone plus S-metolachlor. However, by 5 wk after transplanting few differences were observed between treatments. Fomesafen, linuron with or without S-metolachlor, bicyclopyrone (38 or 49.7 g ai ha−1), pyroxasulfone with or without flumioxazin, metribuzin, and paraquat did not cause injury to sweetpotato slips in any of the studies conducted.

Abstract:
A field experiment was conducted during the kharif and rabi season of 2000-04 at Indian Institute of Pulses Re- search, Kanpur to find out the performance of maize ( Zea mays L.)-chickpea ( Cicer arietinum L.) cropping se- quence with sulphur fertilization along with farmyard manure (FYM). Inorganic S at 0 and 20 kg/ha was applied during kharif maize cultivation and in rabi season, three levels of S (0, 10 and 20 kg/ha) were applied with 2 levels of FYM (0 and 4 t/ha). Maize grain yield increased by 0.59 t with the application of 20 kg S/ha over control (1.99 t/ ha). Significant positive effects of 20 kg/ha of S as manifested on growth, yield attributes, yield, S uptake, S utiliza- tion and economics of maize were not further carried over to following chickpea crop. However, in chickpea nodu- lation, grain and straw yield, protein content, and S uptake significantly increased due to application of sulphur along with FYM application. Higher mean nodule number (19.38), nodule dry weight (0.213 g/plant), grain yield (1.69 t/ha), straw yield (1.78 t/ha), and S uptake (15.6 kg/ha) was found with the 20 kg/ha of S fertilization. But utili- zation of added S decreased with increased S supply. Net return and return per rupee investment of the system also increased due to application of S and FYM to chickpea.

Abstract:
Estimating the size of an insect pest population in an agricultural field is an integral part of insect pest monitoring. An abundance estimate can be used to decide if action is needed to bring the population size under control, and accuracy is important in ensuring that the correct decision is made. Conventionally, statistical techniques are used to formulate an estimate from population density data obtained via sampling. This thesis thoroughly investigates an alternative approach of applying numerical integration techniques. We show that when the pest population is spread over the entire field, numerical integration methods provide more accurate results than the statistical counterpart. Meanwhile, when the spatial distribution is more aggregated, the error behaves as a random variable and the conventional error estimates do not hold. We thus present a new probabilistic approach to assessing integration accuracy for such functions, and formulate a mathematically rigorous estimate of the minimum number of sample units required for accurate abundance evaluation in terms of the species diffusion rate. We show that the integration error dominates the error introduced by noise in the density data and thus demonstrate the importance of formulating numerical integration techniques which provide accurate results for sparse spatial data.

Full text
Abstract:
Data Envelopment Analysis (DEA) is a well-established relative efficiency measurement technique, which has been widely applied to evaluate the technical efficiency of agricultural units in different countries by focusing on different aspects of agricultural production. This research deals with the evaluation of efficiency through DEA in non-homogeneous agricultural production, where units produce a wide range of different outputs. The objectives are threefold. Firstly, we propose a novel methodological approach of integrating the production trade-offs concept of DEA into non-homogeneous agricultural efficiency evaluation to prevent the overstatement of the efficiency of specialist farms and overcome the issue of insufficient discrimination due to large number of outputs in the models. Secondly, we aim to integrate this methodological perspective to the theory of elasticity measurement on DEA frontiers. The efficient frontiers of DEA are not defined in functional forms as in the classical economic theory, therefore obtaining elasticity measures on them require different considerations. We introduce the production trade-offs to the elasticity measurement and derive the necessary models to calculate the elasticities of response in the presence of production trade-offs. As a third objective, before moving to the introduction of the trade-offs in elasticity measurement, for theoretical completeness, we first consider the elasticity measurement on DEA frontiers of constant returns-to-scale (CRS) technologies. Our proposed methodology and all the developed elasticity theory are illustrated in a real world case of Turkish agricultural sectors. We provide extensive empirical applications covering all the proposed theory and methodology. Among the results of this research, we provide an elasticity measurement framework, which enables us to calculate elasticities of response measures in both VRS and CRS technologies, with or without production tradeoffs included. We observe that the integration of production trade-offs provide better discrimination of efficiency scores compared to the models without trade-offs included. We also investigate how changing production trade-offs affect the efficiency and elasticity measures of the evaluated units.

Abstract:

In all times school has defined and categorized pupils from a hypothetical normality. The National Agency for Education is today critical to how the municipalities provide for the necessity of special support for pupils with difficulties in school.

Pupil`s assistants has been a growing profession in school during the last decade and their importance for the pupils is relatively unexplored. The aim of this study is to find out how the pupils think about having pupil`s assistant during the obligatory school on the basis of the ideas of power, knowledge, involvment and understanding. The study is based on qualitative interviews, consisting of half-structured questions, with eight pupils that have or have had pupil`s assistant during their time in senior compulsory school. The result notifies that the pupils feel powerless in school, they have no opportunity to affect and they do not think they are someone that could make any change. With the pupil`s assistant the pupils get an opportunity to affect and a feeling of recognition. The pupil thinks that the pupil`s assistant is a translator of the teachers instructions and someone who builds a bridge between teacher and pupil. There is a fear within the pupils to be different, to not belong. When the pupil`s assistance is given in the classroom the pupil think they belong more to the class than if the assistance is given outside the classroom. With assistance outside the classroom the pupil sees the pupil`s assistant more as a teacher.

Esta pesquisa teve como objetivo analisar o percurso escolar de um estudante ouvinte, bilíngue e com altas habilidades/superdotação (AH/S), filho de mãe surda, que vive em um contexto familiar, onde há cinco línguas envolvidas: Ucraniana, Portuguesa, Alemã, Inglesa e a Libras. A questão problemática investigada é: quais as implicações que esse contexto multilíngue, bem como as AH/S podem trazer para a escolarização do sujeito? O histórico do percurso escolar analisado inicia-se no 1º ano e segue até o 9º ano do ensino fundamental, que compreende as idades entre seis e quatorze anos do sujeito. A pesquisa foi realizada em duas escolas localizadas em uma cidade do interior do Estado do Paraná, onde o sujeito reside com os pais e avós maternos. Os dados da pesquisa foram coletados por meio de entrevistas com professores, psicólogos, diretores, equipe pedagógica, familiares e com o próprio sujeito. Dados de outros estudos (STREIECHEN, 2014) também serão retomados com a finalidade de discutirmos questões linguísticas e escolares do sujeito em questão. Esta pesquisa é de natureza qualitativa, de cunho etnográfico, apoiada em um estudo de caso. A Análise Textual Discursiva (MORAES; GALIAZZI, 2016) foi a Metodologia utilizada para a análise dos dados, uma vez que esse modelo oferece a oportunidade de o pesquisador mergulhar, de um modo mais profundo, na interpretação dos dados, com o compromisso de gerar novas teorias e/ou pressupostos. A Psicanálise foi a Teoria utilizada para respaldar a análise dos dados, visto que essa abordagem aponta conceitos de interesse para a compreensão da relação professor/aluno, entre os quais está a importância da fala e do desejo do educando na aquisição do conhecimento, bem como da escuta mais atenta por parte dos docentes para conhecer o aluno em sua plenitude. Os resultados da pesquisa indicam, entre outros aspectos que: os desafios de aprendizagem do sujeito, nos anos iniciais, não foram relacionados às AH/S, pelo fato de os professores não as identificarem; seu modo peculiar de escrever não foi associado ao seu contexto multilinguístico e/ou às AH/S, mas tomada como erro, uma vez que os professores desconheciam as línguas que envolviam esse sujeito; a ênfase dos docentes estava mais inclinada às dificuldades e menos às habilidades desse aluno. Isso fez com que as dificuldades se acentuassem cada vez mais, levando o educando a desenvolver repúdio pela escola e um total desinteresse pelos estudos. Nossas conclusões inferem para a dificuldade que alguns docentes encontram ao se depararem com alunos com condições peculiares de aprendizagem, visto que, engessados em suas estratégias tradicionalistas e seculares, ficam impossibilitados de ouvir e conhecer o aluno, desconsiderando a vida que fica além dos muros da escola. Portanto, nossa tese é de que, por não carregarem o estereótipo da deficiência, tanto os alunos com AH/S quanto os filhos de pais surdos, tornam-se invisíveis aos olhos de muitos educadores, ficando à margem e fadados ao ‘fracasso’. Defenderemos, portanto, a importância de esses alunos receberem uma atenção especial, por parte da escola, a fim de que não sejam excluídos de um efetivo processo de ensino e aprendizagem.
This study aimed at analyzing the school trajectory of a hearing student, who: is bilingual with high abilities/giftedness (HA/G); has a deaf mother; lives in a familiar context, in which five languages are involved: Ukrainian, Polish, German, English, and Libras. The research question that guided this study was: what are the implications that this multilingual context, as well as the HA/G may have on the participant's schooling? The participant's school trajectory analyzed encompassed the period from 1st to 9th year of the elementary school, at which the participant’s age varied from six to fourteen years old. The study was conducted in two schools located in countryside of Paraná, where the participant resided with his parents and maternal grandparents. The data were collected through interviews with teachers, psychologists, principals, pedagogical staff, family members and the participant himself. Extra data from other studies (STREIECHEN, 2014) were also used in order to discuss the participant’s linguistic and school issues. This is a qualitative study, ethnographic in nature, supported by a case study. The Discursive Textual Analysis (MORAES; GALIAZZI, 2016) was the methodological framework adopted to analyze data in this study, considering that such framework allows the researcher to interpret the data further, with the commitment to generate new theories and/or assumptions. Psychoanalysis was the theory adopted to support data analysis, since this approach points out concepts of interest for comprehending the relationship between teacher and student, to cite: the importance of student's speech and desire to acquire knowledge, as well as of teacher's most attentive listening to become acquainted with a student in his/her amplitude. Results indicated, among other aspects, that: the participant's learning challenges, in the initial school years, were not related to the HA/G, since teachers did not identify such abilities; the participant's peculiar written style was not associated with his multilingual context and/or with the HA/G, but considered as erroneous, once the teachers were not acquainted with the languages experienced by the participant; the teachers' priority relied on the participant's difficulties rather than his abilities. The aspects aforementioned suggested that the participant' struggles intensified more and more, leading him to develop an antipathy for the school and a total indifference for studying. The conclusions pointed to the difficulty that some teachers encounter when they have to work with students with peculiar learning conditions. Such teachers, due to their traditionalist and secular strategies, are unable to listen and become acquainted with their students, disregarding their lives beyond the school walls. Therefore, the thesis of this study is that, because they do not carry the stereotype of disability, both students with HA/G and children of deaf parents become invisible in the eyes of many educators, being isolated and doomed to failure. This study highlights that these students should receive special attention in the scholar environment, so that they are not excluded from an effective teaching and learning process.

Abstract:
Fault tolerance is essential in a production-grade service delivery network. One of the solution is build a clustered environment to keep system failure to a minimum. This thesis examines the use of high availability and load balancing services using open source tools in GNU/Linux. The thesis discusses some general technologies of high availability computing as virtualization, synchronization and mirroring. To build relatively cheap high availability clusters is suitable DRDB tool. DRDB is tool for build synchronized Linux block devices. This paper also examines Linux-HA project, Redhat Cluster Suite, LVS, etc. Content Delivery Networks (CDN) replicate content over several mirrored web servers strategically placed at various locations in order to deal with the flash crowds. A CDN has some combination a request-routing and replication mechanism. Thus CDNs offer fast and reliable applications and services by distributing content to cache servers located close to end-users. This work examines open-source CDNs Globule and CoralCDN and test performance of this CDNs in global deployment.

Abstract:
Abstract In Madagascar, cereal yields remain insufficient due to various biotic and abiotic constraints, including Striga asiatica, a parasitic weed that has contributed to decreased maize yield up to 100%. This work aims to assess the impact of the practice of two cropping systems on the maize crop infested by S. asiatica. PLATA maize seed of the putative tolerant mutant line from the M5 generation after gamma irradiation at 100, 200 and 300 Gy and of the sensitive parent variety were grown in fields naturally infested or artificially inoculated with one pinch of around 3000 ready-to-germinate seeds of S. asiatica. The cropping system (SCV) is a community of plants that is managed by a farm unit to achieve various human goals. The residue of Stylosanthes sp. legumes was used as mulch SCVm and the legume cowpea was planted with the host plant for the intercropping system SCVv. Results have shown that the use of mulch, either residue SCVm or green mulch SCVv, minimizes S. asiatica infestation on maize plants. The SCV reduces significantly the number of emerging Striga plants with an emergence of 1.33 ± 0.36 for SCVm, 4.33 ± 0.27 for SCVv and 15.00 ± 1.08 for the control. Moreover, M5 lines have shown significant differences in plant survival rate of 50.57 ± 1.25% to 80.00 ± 0.91%, versus 13.50 ± 0.47% for the parent variety. Yields of the parent and M5 lines on SCVm are, respectively, 3.46 ± 0.02 t/ha and 4.64 ± 0.01 t/ha, and 2.30 ± 0.04 t/ha and 3.61 ± 0.05 t/ha for SCVv, while that of the control plot remains low, varying from 0.50 ± 0.04 t/ha to 2.29 ± 0.01 t/ha. Cover increases soil humidity and delays the development of S. asiatica and infection of the host plant, thus improving host plant yield. These results demonstrate the benefit of the integrated approach of mutation breeding and cultural practice to ensure more durable crop production under heavy Striga infestation.

Abstract:
Abstract M3 derived mutants from two bread wheat varieties, namely, 'Giza 186' and 'Saha 93', were screened for resistance to the rust Ug99 at two locations in Njoro (Kenya) and in Tihama (Yemen). At Tihama, two mutants of 'Giza 186' (G-M2-2010-1-28 and G-M2-2010-41-52) and four mutants of 'Saha 93' (S-M2-2010-16-12, S-M2-2010-21-13, S-M2-2010-22-14 and S-M2-2010-27-15) were seen to be resistant at both seedling and adult stages while their parents were resistant at seedling stage and susceptible at adult stage. In Kenya, the resistance score of the mutants was slightly different from those obtained at Tihama. The mutants G-M2-2010-1-28 and G-M2-2010-41-52 were stable in their level of resistance recorded at Tihama, but only two mutants of 'Saha 93' (S-M2-2010-16-12 and S-M2-2010-27-15) were resistant at both growth stages. S-M2-2010-22-14 and S-M2-2010-21-13 were resistant at the seedling stage while susceptible at adult stage. Further selection on these mutants for yield potential, agronomic performance and yellow rust disease resistance, as well as on selected mutants of both 'Giza 186' and 'Saha 93', at M5-M6 stages identified superior mutant lines compared with the two parents 'Saha 93' and 'Giza 186'. These included the line Erra-010-GM2w-41-52-40, which ranked first in yield (3768 kg/ha), followed by the lines Erra-010-SwM2-16-12-19, Erra-010-GM2w-1-28-18 and Erra-010-SwM2-22-14-6. Moreover, it can be concluded that Erra-010-GM2w-41-52-40 and Erra-010-SwM2-16-12-19 are highly recommended for their resistance to stem and yellow rust diseases as well as for yield potential and preference by farmers. Therefore, efforts are in progress to increase their seeds for dissemination over a wide range of farmers and wheat areas where rust diseases are an epidemic, and for registration of the lines as improved mutant varieties.

Non portò invece a compimento il De pontificibus, opera dove la storia della Chiesa ha inizio con san Pietro per arrivare a Clemente V, a differenza del coetaneo Bartolomeo Platina che, partendo dalla vita di Cristo, era arrivato fino a Sisto IV.

Abstract:
Il contributo prende in esame alcune gallerie figurate di “Asceti illustri”, rappresentati in piedi (stanti) come sculture oppure a mezzo busto entro clipei, secondo un’iconografia ricalcata sulle figurazioni civiche degli Uomini famosi, proprie specialmente della temperie umanistica. L’indagine, condotta sull’area toscana ha mostrato come questo genere di figurazioni, all’apparenza singolare, trovi una significativa attestazione già nei primi decenni del Trecento nel coro della cattedrale di Orvieto e, come mostrano gli esempi successivi, inizialmente non sembra legata esclusivamente a commissioni monastiche, come invece si sarebbe potuto ritenere, visto che queste teorie di “illustri” esaltano le virtù dei Padri del monachesimo, non solo occidentale. Questo genere figurativo appare dunque trasversale, e rispecchia via via motivazioni e ragioni diverse a seconda dei contesti e delle intenzioni dei committenti, ma sempre con coerenza e autonomia semantica, al pari della più nota e studiata tradizione civica e laica degli Uomini famosi.

Abstract:
Romania�s physical-geographical and lithological complexity creates a great diversity of climatic and pedological conditions, which determines the richness of the types of ecosystems and habitats, as well as the presence of five biogeographical regions, including the Alpine bioregion. In Romania this biogeographical region includes both Carpathians peaks and coniferous and mixed forests of the Carpathians, but also the intermountain depressions and higher hills along the mountain chain. Various mountains are home to endemic and relic species, virgin and quasi-virgin natural forests, virtually extinct from the rest of the European Union with a special biological diversity. The purpose of this paper is to present a study on the number and distribution of protected natural areas, their area and share in the Alpine biogeographical region of Romania in relation to the entire EU bioregion. The Digital Elevation with spatial resolution model at 25 m and geospatial data were used to develop this study. In Romania, the Alpine bioregion occupies an area of 5.005.266.03 ha, of which 3.726.354.88 ha, respectively 74,42% is included in different categories of protected natural areas: SPA�s = 1.133.419,10 ha; SCI�s = 1.760.940,84 ha; wetland of international importance = 695,93 ha; scientific reservations = 5,77 ha; natural reservations = 137.503,29 ha; biosphere reservations = 85.518,26 ha; national parks = 202.741,98 ha; natural parks = 405.520,97 ha; natural monuments = 8,73 ha. Due to a partial or total overlap of the protected areas, the range of protected areas in the territory (soil footprint) is 2.147.431.78 ha.

Abstract:
The effects on thrombus formation and bleeding of various heparin(oid)s were studied at several time-intervals: in addition, the αXa-, αiia-, and thrombin generation inhibitory (IIaGI)-activities were measured amidolytically in plasma from these animals. The following substances were studied: heparin (HEP), the fraction of heparin with high affinity for ATIII (HA-HEP), a low molecular weight fraction of heparin (LMW-HEP), nitrous acid degraded heparin (NAD-HEP), FragrainR (FRA), Org 10172 and the fraction of Org 10172 with high affinity for ATIII (HA-10172). The substances were given in a dose of 800 αXa U/kg i.v. in the thrombosis model and in the double dose (1600 αXa U/kg i.v.) in the bleeding model because of the lower intrinsic effect on bleeding. The initial magnitude and the duration of the anti-thrombotic and bleeding enhancing effects of these substances are summarized in the table together with the half-lives of the αXa-, αia- and IIaGI-activities. NE: not estimated due to too low alla-activities.The following conclusions could be drawn concerning the duration of the effects: 1. in contrast with HEP most lower molecular weight substances showed different time courses of the anti-thrombotic and the bleeding enhancing effect 2. the duration of the antithrombotic effect of Org 10172 and HA-10172 is considerably longer than that of the other substances 3. the duration of the bleeding enhancing effect of Org 10172, HA-10172, NAD-HEP and FragminR is shorter than that of HEP, HA-HEP and LMW-HEP. Additional conclusions could be drawn by inspecting the time response curves and taking the magnitude of the effects into account: 4. Org 10172 and its high affinity fraction have a better benefit/risk ratio in comparison with the other substances, which even increases in time 5. the time-response curves of the anti-thrombotic effects seem to be associated with those of the aXa-activities and 6. the time-response curves of the bleeding enhancing effects seem to be related to those of thrombin inactivation.

Abstract This paper investigates the influence of spraying current and gun transverse speed on the characteristics of the hydroxyapatite (HA) and Ti-6A1-4V composite coatings. Two different kinds of feedstock are being used; HA and Ti-6A1-4V in the ratio of 80 v/t. %: 20 wt. % and 50 wt. %: 50 wt. % respectively. The paper investigates the influence of the plasma spray currents at 600 A, 800 A, and 1000 A and the influence of the feed speeds of the spray gun at 250 mm/s, 500 mm/s, and 750 mm/s. It examines the powders or coatings using an Instron machine, XRD, and scanning electron microscopy. It is found that a spraying current of l000 A, relative to 600 A and 800 A, gives a coating that is less porous and composed of a well-splayed structure. It also yields the highest bond strength among the coatings. Paper includes a German-language abstract.

Abstract:
The influence of Raskila bioorganic fertilisers on the productivity of conventional winter wheat ‘Olivin’, was investigated in order to stimulate and save synthetic herbicide Arrat and fungicide Tango Super for spring spraying. Scheme of treatment: 1. Control; 2. Winter wheat sprayed (BBCH 20-29) with fertilizer Raskila 3 l ha-1; 3. Winter wheat sprayed (BBCH 20-29) with Arrat 0.2 kg ha-1+Tango super 1.5 l ha-1; 4. Winter wheat sprayed (BBCH 20-29) with Arrat 0.2 kg ha-1+Tango super 1.5 l ha-1+Raskila 3.0 l ha-1; 5. Winter wheat sprayed (BBCH 20-29) with Arrat 0.1 kg ha-1+Tango super 0.75 l ha-1+Raskila 3.0 l ha-1. The best result in the period of 2014-2016 was received after application of the following combination in spring: Arrat + Tango super + Raskila. This combination allows to reduce the rate of pesticides in half (50%), the differences compared to control are significant, statistically reliable. A statistically significant increase in the following winter wheat ‘Olivin’ quality parameters was found: protein 13.1-14.8%, gluten 24.3-29.7%, number of falls 228-292 s, starch 65.7-70.0%. Application of Raskila fertilizers has raised the grain quality class. The best results were in variants 3 and 4, where the I class of grain quality was achieved. Combination of Raskila fertilisers and pesticides: herbicide Arrat and fungicide Tango super statistically significantly increased the following winter wheat ‘Olivin’ characteristics - plant height 101.2-104.2 cm, ear length 6.9-7.1 cm, grain number per ear 28,96- 30.02, grain yield 6.71-7.03 t ha-1. Application of Raskila fertilizer 1.0 l ha-1 and herbicide Arrat 0.1 kg ha-1 decreased the number of weeds from 62.5 to 57.6 units per m2 and the weed weight decreased from 41.30 to 33.70 g m2. Stronger wheat crop overshadowed weeds better. Combination of Raskila and Tango super reduced the prevalence and severity of diseases in winter wheat such as Septoria spp., Pyrenophora tritici-repentis, Erysiphe graminis, powdery rust (Puccinia recondita).

The effects of various heparin(oid)s, standard heparin VII (SH), dermatan sulphate (DS), a low molecular weight fraction of heparin (UMW-H), FragminR (FRA), Org 10172 = low molecular weight heparinoid, the fraction of Org 10172 with high affinity for AT-III (HA-10172) and the low affinity fraction (LA-10172) respectively were examined on in vitro thrombin generation and inactivation.Thrombin inactivation in the presence of either heparin cofactor II (HC-II) or anti-thrombin III (AT-III) was assessed with two newly developed assays using the purified cofactors, thrombin and chromogenic substrate S2238 on microtiterplates. Thrombin generation in the presence of HC-II and AT-III was studied using purified factor Xa, prothrombin and blood platelet lysate and the residual thrombin activity was assessed amidolytically.The inhibition of the compounds on thrombin activity are summarized in the tableThe following conclusions can be drawn:- SH, LMW-H, HA-10172 and FRA potentiate the AT-III mediated inactivation of Ha more strongly than the HC-II mediated inactivation.- DS and LA-10172 show the reverse pattern of inactivation, while Org 10172 potentiates both inactivaton pathways to a similar extent.Thrombin generation in the presence of HC-II is inhibited by mw-heparin(oid)s at approx. 2-5 times lower concentrations than the HC-II mediated thrombin inactivation, while the inhibiting effect of SH in both assays is comparable.AT-III mediated thrombin generation inhibition and AT-III mediated thrombin inactivation is comparable as well for SH, LMW-H and FRA. In contrast, Org 10172 and its subfractions are approx. 10 times more potent on AT-III mediated thrombin generation inhibition than on AT-III mediated thrombin inactivation.Org 10172 shows low anti-thrombin activity and this activity is mainly mediated via FC-II.

Abstract:
Dense white mustard (Sinapis alba L.) can suppress weeds, however excessive density negatively influences crop yields. The search for the optimal parameters for applying mineral fertilizers and the consumption of seed material will increase the crop yield and will improve its competitive ability. This work aimed to identify the seeding rate and doses of nitrogen fertilization at which white mustard plants can actively suppress weeds without reducing the productivity of the crop. In the course of this research, we established that S. alba sown at a rate of 2, 2.5 and 3 million seeds per ha suppressed the growth and development of weeds as much as possible. On average, in 2017-2019, the dry weight of weeds in the aforementioned variants was the least and reached 57.9; 42.3 and 38.4 g/m2, respectively. Weed species composition and quantitative parameters of weed infestation depended on the weather conditions of the year. The application of nitrogen fertilizer did not affect significantly the weediness of S. alba crops. The optimal density white mustard plant formed at a seeding rate of 2 million units/ha and, on average, for three years of research, the seed yield in this variant was the highest (0.6 t/ha).

Abstract:
Studies were conducted to characterize the biosynthesis of von Willebrand factor (vWf) by cultured endothelial cells (EC) derived from the umbilical vein of a patient with type HA von Willebrand’ s disease. The patient’ s EC, compared with those from normal individuals, produced vWf which had decreased amounts of large multimers and an increase in rapidly migrating satellite species, features which are characteristic of plasma vWf from patients with type IIA von Willebrand’ s disease. The typQ IIA EC produced a full spectrum of vWf multimers in both cell lysates and post-culture medium, although the relative amounts of the larger species were decreased. The large multimers were degraded in conjunction with the appearance of rapidly migrating satellites which contained =170 kDa proteolytic fragments. Kinetic studies demonstrated that the =170 kDa species is not a primary translation product Normal metabolically labeled vWf, incubated with either the patient’ s EC or medium conditioned by these cells, was not similarly degraded. These results demonstrated that this patient’ s clinical phenotype is due to abnormal proteolysis and not to a primary failure of subunit oligomerization. Moreover, the increased degradation is attributable to increased proteolytic sensitivity of an abnormal vWf molecule rather than to pathologically elevated levels of endogenous proteases. Experiments using monoclonal antibodies which recognize either N- or C-associated epitopes have localized the defect to the N-terminal portion of the vWf molecule, which is believed to be involved in the inter-dimer polymerization reaction. The type DA EC also contained a single vWf mRNA species which comigrated with that from normal EC. However, the type HA EC contained 8-10 fold more vWf mRNA than their normal counterparts. These results suggest that the functional defect in this patient is caused by a subtle mutation in the vWf coding sequence leading to increased proteolytic sensitivity of its protein product

Abstract:
El constante éxodo demográfico del mundo rural desde finales del siglo XX ha desembocado en la llamada “España vaciada” o “España despoblada”, un fenómeno generalizado que ha afectado incluso a espacios demográficamente estables como el histórico Campo de Calatrava, en la provincia de Ciudad Real. Esta situación ha hecho que las instituciones vuelvan la mirada hacia recursos del patrimonio cultural, olvidados hasta el momento, con el fin de valorizarlos o de transformarlos en recursos turísticos capaces de actuar como agentes dinamizadores de un territorio cada vez más deprimido. El objetivo de este estudio es mostrar la investigación y las actuaciones desarrolladas durante los dos últimos años en el castillo de Salvatierra (ss. XI-XIII) y su fortín anejo del castillo de Los Cristianos (s. XIII), ambos en el término municipal de Calzada de Calatrava. Gracias a los acuerdos firmados en 2019 entre el Ayuntamiento, la propiedad de los terrenos en los que se levanta Salvatierra y la Universidad de Castilla-La Mancha, se ha desarrollado un ambicioso proyecto cuyo equipo de trabajo se ha conformado por destacados profesionales del ámbito académico, la arqueología, la virtualización y reconstrucción 3D del patrimonio así como de la restauración monumental, cuya metodología de trabajo se ha fundamentado en la investigación, la protección y la difusión. Los resultados han sido plenamente satisfactorios en tanto que se han obtenido sin practicar excavaciones arqueológicas de calado. Entre los más sobresalientes, destaca la apertura por primera vez al público de estas dos fortificaciones mediante visitas guiadas.

Abstract:
The present study examines the relationships between structure (floristic composition, dendrometric parameters), diversity (diversity and evenness indexes) of urban forest park stands and the ecological (soil fertility, soil moisture), environmental factors (air pollution). The study is based on the forest park stands inventory data, performed from 2012 to 2017 in Kryvyi Rih City, Central Ukraine. The floristic compositions of the urban forest park stands are poor. There are only 23 species that belong to 14 families and 12 genera. More families were represented by at least more than 2% of taxon diversity. While Ulmaceae (2 genera, 4 species–17,39 %), Fabaceae (3 genera, 2 species–17,39 %), Aсеrасеае (1 genera, 4 species–17,39 %) were the most representative families. It was established that at forest park the values of stand density varied from 490 to 660 trees*ha-1, stem heights were from 26 to 31 m, stem diameters were from 13 to 17 cm, stand basal area were from 32 to 49 m2*ha-1, stand volume were from 200 to 415 m3*ha-1. the values of relative stem heights were from 0,63 to 0,82 m*year-1, relative stem diameters were from 0,31 to 0,43 cm*year-1, relative stand basal area were from 0,80 to 1,19 m2*ha-1*year-1, relative stand volume were from 5,45 to 10,28 m3*ha-1*year-1. The varied values of the forest park stands index (Shannon-Wiener diversity index from 0,75 to 1,61, Pielou‟s evenness index from 0,53 to 0,86, Simpson‟s diversity from 0,24 to 0,60, Margalef‟s diversity index from 0,87 to 6,97) indicate the ecological instability of these woody plant communities. Current state of the urban forest park stands determined by the combined influence of ecological (soil fertility, soil moisture) and environmental factors (air pollution).

Full text
Abstract:
The Big Thicket National Preserve (BITH) vegetation inventory project classified and mapped vegetation within the administrative boundary and estimated thematic map accuracy quantitatively. National Park Service (NPS) Vegetation Mapping Inventory Program provided technical guidance. The overall process included initial planning and scoping, imagery procurement, vegetation classification field data collection, data analysis, imagery interpretation/classification, accuracy assessment (AA), and report writing and database development. Initial planning and scoping meetings took place during May, 2016 in Kountze, Texas where representatives gathered from BITH, the NPS Gulf Coast Inventory and Monitoring Network, and Colorado State University. The project acquired new 2014 orthoimagery (30-cm, 4-band (RGB and CIR)) from the Hexagon Imagery Program. Supplemental imagery for the interpretation phase included Texas Natural Resources Information System (TNRIS) 2015 50 cm leaf-off 4-band imagery from the Texas Orthoimagery Program (TOP), Farm Service Agency (FSA) 100-cm (2016) and 60 cm (2018) National Aerial Imagery Program (NAIP) imagery, and current and historical true-color Google Earth and Bing Maps imagery. In addition to aerial and satellite imagery, 2017 Neches River Basin Light Detection and Ranging (LiDAR) data was obtained from the United States Geological Survey (USGS) and TNRIS to analyze vegetation structure at BITH. The preliminary vegetation classification included 110 United States National Vegetation Classification (USNVC) associations. Existing vegetation and mapping data combined with vegetation plot data contributed to the final vegetation classification. Quantitative classification using hierarchical clustering and professional expertise was supported by vegetation data collected from 304 plots surveyed between 2016 and 2019 and 110 additional observation plots. The final vegetation classification includes 75 USNVC associations and 27 park special types including 80 forest and woodland, 7 shrubland, 12 herbaceous, and 3 sparse vegetation types. The final BITH map consists of 51 map classes. Land cover classes include five types: pasture / hay ground agricultural vegetation; non ? vegetated / barren land, borrow pit, cut bank; developed, open space; developed, low ? high intensity; and water. The 46 vegetation classes represent 102 associations or park specials. Of these, 75 represent natural vegetation associations within the USNVC, and 27 types represent unpublished park specials. Of the 46 vegetation map classes, 26 represent a single USNVC association/park special, 7 map classes contain two USNVC associations/park specials, 4 map classes contain three USNVC associations/park specials, and 9 map classes contain four or more USNVC associations/park specials. Forest and woodland types had an abundance of Pinus taeda, Liquidambar styraciflua, Ilex opaca, Ilex vomitoria, Quercus nigra, and Vitis rotundifolia. Shrubland types were dominated by Pinus taeda, Ilex vomitoria, Triadica sebifera, Liquidambar styraciflua, and/or Callicarpa americana. Herbaceous types had an abundance of Zizaniopsis miliacea, Juncus effusus, Panicum virgatum, and/or Saccharum giganteum. The final BITH vegetation map consists of 7,271 polygons totaling 45,771.8 ha (113,104.6 ac). Mean polygon size is 6.3 ha (15.6 ac). Of the total area, 43,314.4 ha (107,032.2 ac) or 94.6% represent natural or ruderal vegetation. Developed areas such as roads, parking lots, and campgrounds comprise 421.9 ha (1,042.5 ac) or 0.9% of the total. Open water accounts for approximately 2,034.9 ha (5,028.3 ac) or 4.4% of the total mapped area. Within the natural or ruderal vegetation types, forest and woodland types were the most extensive at 43,022.19 ha (106,310.1 ac) or 94.0%, followed by herbaceous vegetation types at 129.7 ha (320.5 ac) or 0.3%, sparse vegetation types at 119.2 ha (294.5 ac) or 0.3%, and shrubland types at 43.4 ha (107.2 ac) or 0.1%. A total of 784 AA samples were collected to evaluate the map?s thematic accuracy. When each AA sample was evaluated for a variety of potential errors, a number of the disagreements were overturned. It was determined that 182 plot records disagreed due to either an erroneous field call or a change in the vegetation since the imagery date, and 79 disagreed due to a true map classification error. Those records identified as incorrect due to an erroneous field call or changes in vegetation were considered correct for the purpose of the AA. As a simple plot count proportion, the reconciled overall accuracy was 89.9% (705/784). The spatially-weighted overall accuracy was 92.1% with a Kappa statistic of 89.6%. This method provides more weight to larger map classes in the park. Five map classes had accuracies below 80%. After discussing preliminary results with the parl, we retained those map classes because the community was rare, the map classes provided desired detail for management or the accuracy was reasonably close to the 80% target. When the 90% AA confidence intervals were included, an additional eight classes had thematic accruacies that extend below 80%. In addition to the vegetation polygon database and map, several products to support park resource management include the vegetation classification, field key to the associations, local association descriptions, photographic database, project geodatabase, ArcGIS .mxd files for map posters, and aerial imagery acquired for the project. The project geodatabase links the spatial vegetation data layer to vegetation classification, plot photos, project boundary extent, AA points, and PLOTS database sampling data. The geodatabase includes USNVC hierarchy tables allowing for spatial queries of data associated with a vegetation polygon or sample point. All geospatial products are projected using North American Datum 1983 (NAD83) in Universal Transverse Mercator (UTM) Zone 15 N. The final report includes methods and results, contingency tables showing AA results, field forms, species list, and a guide to imagery interpretation. These products provide useful information to assist with management of park resources and inform future management decisions. Use of standard national vegetation classification and mapping protocols facilitates effective resource stewardship by ensuring the compatibility and widespread use throughout NPS as well as other federal and state agencies. Products support a wide variety of resource assessments, park management and planning needs. Associated information provides a structure for framing and answering critical scientific questions about vegetation communities and their relationship to environmental processes across the landscape.

Abstract:
In 2009, the Heartland Inventory and Monitoring Network initiated bird surveys on Effigy Mounds National Monument to monitor changes in bird community composition and abundance and improve our understanding of relationships between breeding birds and their habitat and the effects of management actions on those relationships. This information helps park staff plan management objectives and assess the effectiveness of management alternatives. We evaluated park breeding bird trends in the context of trends observed within the North American Bird Conservation Initiative?s Prairie Hardwood Transition Bird Conservation Region where the park is located. This allows us to assess the influence of park habitat management on bird populations with an understanding of regional population trends that are outside the influence of natural resource management activities at the park. In 14 years (2009?2022) of monitoring, 111 bird species have been recorded on the park, 93 of which are considered breeding species (permanent or summer residents). Eight of these are species of concern for the Prairie Hardwood Transition Bird Conservation Region. Thirty-eight species were observed in sufficient numbers to calculate annual abundances and trends with some degree of statistical confidence. The American Redstart, American Robin, Baltimore Oriole, Eastern Wood-pewee, and Red-eyed Vireo were the most abundant and widespread species on the park. Regional trends (2009?2019; Sauer et al. 2020) were similar to those seen on the park with a few exceptions. American Robin, Brown-headed Cowbird, Common Grackle, and White-breasted Nuthatch were declining within the region but increasing within the park. Diversity, richness, and evenness in distribution of individuals across species in the breeding bird community on the park were unchanged over the 14 years. When sampled, habitats on the plots at Effigy Mounds National Monument consisted primarily of the woodland type, with lesser amounts of other types present. Canopy cover averaged 61 to 89% on plots with cover provided exclusively by hard?wood trees. Basal area of hardwood trees averaged between 12 and 22 m2/ha, and canopy height averaged between 20 and 23 m. Tree species from 14 different families contrib?uted to the canopy cover and basal area of plots. Plots were primarily unvegetated at ground level, with deciduous litter and woody debris common and bare soil exposed. Total foliar cover at ground level on plots consisted primarily of forbs.

This information helps park staff plan management objectives and assess the effectiveness of management alternatives. We evaluated park breeding bird trends in the context of trends observed within the North American Bird Conservation Initiative?s Prairie Potholes Bird Conservation Region where the park is located. This allows us to assess the influence of park habitat management on bird populations with an understanding of regional population trends that are outside the influence of natural resource management activities at the park. In 14 years (2009?2022) of monitoring, 109 bird species were recorded on the park. Ninety-two of the species are considered breeding species (permanent or summer residents). Seven of these are species of concern for the Prairie Potholes Bird Conservation Region. Fifteen species were observed in sufficient numbers to calculate annual abundances and trends with some degree of statistical confidence. The Bobolink, American Robin, and Red-winged Blackbird were the most abundant and widespread species on the park. Comparisons of regional trends (2009?2019; Sauer et al. 2020) with park trends were inconclusive. Trends in 14 of the 15 abundant species on the park were uncertain. Common Yellowthroat was moderately increasing on the park. Regionally, American Robin, Dickcissel, and Yellow Warbler were increasing; the Bobolink, Clay-colored Sparrow, Eastern Kingbird, Grasshopper Sparrow, and Ring-necked Pheasant were declining; and the remaining seven species had uncertain population trends. Diversity, richness, and evenness in distribution of individuals across species in the breeding bird community on the park were unchanged over the 14 years. When sampled, habitats on the plots at Pipestone National Monument consisted primarily of the old field/prairie vegetation type, with lesser amounts of other types present. Canopy cover of hardwood trees averaged 5 to 7% on plots, basal area averaged 1 to 2 m2/ha, and canopy height averaged between 1 and 3 m. Tree species from 10 different families contrib?uted to the canopy cover and basal area of plots. Plots sampled were primarily unvegetated at ground level, with grass litter common, and rock and bare soil exposed. Total foliar cover at ground level on plots consisted primarily of cool season grasses and forbs.

Abstract:
In 2005, the Heartland Inventory and Monitoring Network initiated bird surveys on Herbert Hoover National Historic Site to monitor changes in bird community composition and abundance and improve our understanding of relationships between breeding birds and their habitat and the effects of management actions on those relationships. This information helps park staff plan management objectives and assess the effectiveness of management alternatives. We evaluated park breeding bird trends in the context of trends observed within the North American Bird Conservation Initiative?s Eastern Tallgrass Prairie Bird Conservation Region where the park is located. This allows us to assess the influence of park habitat management on bird populations with an understanding of regional population trends that are outside the influence of natural resource management activities at the park. Seventy-four species of birds were recorded in 18 years (2005?2022). Seventy-one of the species are considered breeding species (permanent or summer residents). Seven of these are species of concern for the Eastern Tallgrass Prairie Bird Conservation Region. Nine species were observed in sufficient numbers to calculate annual abundances and trends with some degree of statistical confidence. The Red-winged Blackbird, American Robin and Dickcissel were the most abundant and widespread species on the park. Comparisons of regional trends (2005?2019; Sauer et al. 2020) with park population trends were inconclusive. Trends in the nine abundant species on the park were uncertain. Regionally, Dickcissel and Northern Cardinal were increasing. However, American Goldfinch, American Robin, Common Grackle, Common Yellowthroat, Eastern Meadowlark, Mourning Dove, and Red-winged Blackbird were declining regionally. Diversity, richness, and evenness in distribution of individuals across species in the park breeding bird community were unchanged over the 18 years. When sampled, habitats on the plots at Herbert Hoover National Historic Site consisted primarily of the old field/prairie type, with lesser amounts of other types present. Canopy cover averaged 2 to 13% on plots, with cover provided primarily by hard?wood trees. Basal area of hardwood trees averaged between 1 and 2 m2/ha, and canopy height averaged between 4 and 5 m. Tree species from 12 different families contrib?uted to the canopy cover and basal area of plots. Plots were primarily unvegetated at ground level, with grass litter common and bare soil exposed. Total foliar cover at ground level on consisted primarily of cool season grasses and forbs.
