Abstract During the operation of large industrial installations, a very important task is to maintain the proper technical state. In the event of an emergency, it is vital to locate the place of occurrence as soon as possible. In solving this type of problem, it often helps to apply the methods of measurement associated with ionizing radiation. One of these methods is the gamma scanning. The purpose of this type of measurement is the detection and localization of disturbance of technological processes which may result in incorrect decomposition the fl owing medium and workpiece (sediments, congestion) as well as damage to the internal constructions. A particularly: (i) preventive diagnosis - early detection of installation failure; (ii) rationalization of repairs and renovations - to determine the need to take or not to take remedial action; (iii) quick and precise installation inspections - to gain knowledge of the technical condition and technological installations; (iv) indication of worn parts and posing a threat - diagnostics of the technical condition installation; (v) forecasting the useful lifetime of equipment.

In response to the concerns White raises in his technical comment on Rickles, Heppen, Allensworth, Sorensen, and Walters (2018), we discuss whether it would have been appropriate to test for nominally equivalent outcomes, given that the study was initially conceived and designed to test for significant differences, and that the conclusion of no difference was not solely based on a null hypothesis test. To further support the article’s conclusion, confidence intervals for the null hypothesis tests and a test of equivalence are provided.

AbstractThe radon issue has been known worldwide for dozens of years. Many scientific (ICRP Publication No. 137), technical (ICRU Report No. 88), and legislative (Council Directive 2013/59/EURATOM (EU-BSS)) documents have been published in the last decade. More and more attention is being paid to precise quantification to determine the concentration and consequent effects of various pollutants on human health worldwide. The quality of measurement and the variety of measurement techniques increase the need to unify measurement procedures and metrology continuity. Countries around the world are beginning to unify metrological procedures for determining different quantities based on international recommendations and standards. Not only for these reasons, it became more actual a need for more accurate radon activity concentration measurement and radon metrology unification. This paper summarizes the main remarks and technical aspects to the historical development of radon metrology.

This study determined the behavioral skill outcome of technical education students engaged in cooperative learning. Specifically, the study sought to identify the effects of cooperative learning on technical education student’s communication skill, problemsolving skill and critical thinking skill. There were three research questions posed, and the analysis was driven by three null hypotheses tested at (P<.05) level of significance. It has adopted a quasi-experimental design for the study and intact classes were assigned to treatment groups. The study's population was 41 students of Technical Education (TE), consisting of 41 year 3 students of Industrial Technical Education at the University of Nigeria, Nsukka, which was the treatment group allocated to the teaching method of cooperative learning. The instrument used for data collection was the self-assessment inventory of communication skills (CSSAI), the inventory of problem-solving skills (PSSI), and the California Critical Thinking Skills Test (CCTST). Three technical education experts had subjected the instruments to face and content validation. Mean and standard deviation were used to answer the study questions while Paired-sample t-test was used to answer the null hypotheses. Findings showed, among others, that there is a significant difference between the pretest and posttest mean scores taught by Automobile Lighting System students who use cooperative learning in terms of behavioral skill outcome. Among others, it was proposed that technical education teachers be encouraged to use the cooperative learning method in teaching automotive lightening program.

Full textAbstract:
Abstract The occurrence of referential Null Objects (NOs) is a recurrent syntactic feature of ancient Indo-European languages. As previous scholars have remarked, different conditions license the occurrence of NOs in individual languages. In Hittite, the occurrence of NOs has already been observed in reference works, but a systematic account of this phenomenon is still a desideratum. In this paper, we provide a thorough corpus-based study of NOs in a corpus of Old Hittite texts. By means of quantitative data, we illustrate the frequency of NOs in various contexts, and highlight their co-occurrence with sentence connectives, chiefly with ta. We also take into account other parameters that influence the occurrence of NOs. Our analysis shows that in Hittite NOs display a connection with inanimate and less individuated referents and seem to be driven by discourse rather than by syntactic motivations. In addition, textual genre also seems to play role, and we suggest that NOs constitute a feature of the technical language of festivals and ritual texts. Finally, we sketch a possible diachronic scenario that explains the observed distribution of NOs, and argue that Old Hittite attests a phase of ongoing change whereby NOs were being progressively replaced by clitic object pronouns.

A modified PennHIP procedure (MPP), using specific mechanical holding devices, was used on 70 dogs and compared to the standard PennHIP method (SPM) used on 39 dogs, in terms of technical effectiveness and the mean number of essential individuals within the X-ray room (EIXRR). The data using the Chisquared test were consistent with the null hypothesis that the technical effectiveness was equal in the groups under investigation (P > 0.05). On the contrary, using the two-sample unpaired t -test the null hypothesis, that the mean EIXRR was equal, was rejected (P < 0.001). The estimated EIXRR was 3.4 ± 0.7 and 5.7 ± 1.2 (mean ± SD) for MPP and SPM, respectively. In conclusion, the MPP needs fewer EIXXR than the SPM and complies with the new recommendations in X-ray protection, which introduce the ALARA (as-low-as-reasonably-achievable) idea.

Abstract Photon beams with wide energy ranges from 4 MV to 25 MV are commonly used in radiotherapy nowadays. In recent years, there has been a strong interest in a certain modification of a radiotherapeutic apparatus by the application of the so-called flattening filter-free (FFF) beam. Several advantages of FFF beams over standard flattening filter (FF) beams are noticed, and this technical solution has aroused great interest among radiotherapeutic facilities. The goal of the present study is to investigate the differences between the conventional FF and unflattened FFF 6-MV and 10-MV photon beams in some basic dosimetric parameters and their influence on the whole radiotherapeutic treatment. The data provided here include the detailed characteristics as follows: percent depth dose (PDD), beam profile, edge of a half-profile, total scatter correction factor (TSCF) and head scatter correction factor (HSCF) for FF and FFF 6-MV and 10-MV photon beams from the Elekta Versa HD accelerator in the Katowice Oncology Center in Poland.

Full textAbstract:
This paper presents theoretical and experimental aspects of Jacobian nullspace use in kinematically redundant robots for achieving kinetostatically consistent control of their compliant behavior. When the stiffness of the robot endpoint is dominantly influenced by the compliance of the robot joints, generalized stiffness matrix can be mapped into joint space using appropriate congruent transformation. Actuation stiffness matrix achieved by this transformation is generally nondiagonal. Off-diagonal elements of the actuation matrix can be generated by redundant actuation only (polyarticular actuators), but such kind of actuation is very difficult to realize practically in technical systems. The approach of solving this problem which is proposed in this paper is based on the use of kinematic redundancy and nullspace of the Jacobian matrix. Evaluation of the developed analytical model was done numerically by a minimal redundant robot with one redundant d.o.f. and experimentally by a 7 d.o.f. Yaskawa SIA 10F robot arm.

Full textAbstract:
This paper is devoted to the controllability of linear systems of two coupled parabolic equations when the coupling involves a space dependent first order term. This system is set on an bounded interval I ⊂⊂ R, and the first equation is controlled by a force supported in a subinterval of I or on the boundary. In the case where the intersection of the coupling and control domains is nonempty, we prove null controllability at any time. Otherwise, we provide a minimal time for null controllability. Finally we give a necessary and sufficient condition for the approximate controllability. The main technical tool for obtaining these results is the moment method.

Full textAbstract:
Introduction. This article makes a null hypothesis about the impossibility of the existence of material and technical resources as an independent object of study, because these resources cann’t be profitable or social effective without other resources. It is clear that material and technical resources become productive when interacting with financial, informational, innovative, time and other types of resources. The emergence of alternative energy sources, constant change of laws, improvement of construction technology, constant struggle for resources, changing financial vectors place new demands on the material and technical resources of construction and require new approaches to accounting and control. The purpose of the study is to formulate a definition of «material and technical resources» and identify their relationship with other resources in construction. Research methods. In the article has been used general scientific and specific research methods, in particular: comparison – to study of theoretical research of the conceptual and categorical apparatus of material and technical resources, and also assets and resources; graphic - to study the amount of capital investment in housing; analysis and synthesis - to identify ways of interaction of material and technical and other types of resources. Results of the research. In the study detected differences in the definition of «resources» and «assets». It is recognized that the concept of «resources» is broader than – «assets», which allows to distinguish these two definitions for future analysis of their components. Based on the analysis of the concepts of «material» and «technical» resources, the author’s definition of «material and technical resources» is formulated. To existing definitions is added that material and technical resources are one of the main elements of entrepreneurial potential, and also that their use brings not only profit, but also social effect, especially in construction. In addition, the relationship between logistics and other resources has been disclosed. The null hypothesis has been proved, it’s about material and technical resources which are not effective without connections with other resources, and their potential is assessed under the condition of interaction with financial, informational, organizational and time resources. Perspectives. In future studies, it’s advisable to disclose the genesis of material and technical resources; identify the main problems of their formation and efficiency of use; to assess the dynamics and trends of the behavior of analytical indicators and make appropriate proposals; develop a model of the relationship of material, technical and financial resources in accounting and control etc.

We review the current status of large ring laser gyroscopes having the potential to contributeto terrestrial measurements of general relativistic precessions. At this point in time, although thesedevices possess the raw sensitivity for such a measurement, they remain limited by long-term geometricinstability, detection noise and imperfections in the physical models required to isolate geophysicaleffects. Furthermore, minute non-reciprocal biases provide a null-shift error and therefore no currentlyconstructed laser system meets the requirement of absolute rotation rate sensing. Nevertheless, we are ofthe view that these are surmountable problems and the ability of ring laser gyroscopes to measure lowfrequency to DC signals has vastly increased in the last decade.

In this paper and its successor, we make an application of the hyperboloidal foliation method in [Formula: see text] space-time dimension. After the establishment of some technical tools in this paper, we will prove further the global existence of small regular solution to a class of hyperbolic system composed by a wave equation and a Klein–Gordon equation with null couplings. Our method belongs to vector field method and, more precisely, is a combination of the normal form and the hyperboloidal foliation method.

Abstract This paper concerns important and difficult problems connected with a design and construction of thermonuclear reactors, which have to use nuclear fusion reactions of heavy isotopes of hydrogen, i.e., deuterium (D) and tritium (T). There are described conditions in which such reactions can occur, and different methods of a high-temperature plasma generation, i.e., high-current electrical discharges, intense microwave pulses, and injection of energetic neutral atoms (NBI). There are also presented experimental facilities which can contain hot plasma for an appropriate period, and particularly so-called tokamaks. The second part presents the technical problems which must be solved in order to build a thermonuclear reactor, that might be used for energetic purposes. There are considered problems connected with a choice of constructional materials for a vacuum chamber, its internal parts, external windings generating a magnetic field, and necessary shields. The next part considers the handling of radioactive tritium; the using of alpha particles (4He) for additional heating of plasma; recuperation of hydrogen isotopes absorbed in the tokamak internal parts, and a removal of a helium excess. There is presented a scheme of a future thermonuclear power plant and critical comments on a road map which should enable the construction of an industrial thermonuclear reactor (DEMO).

Abstract The present work is a contribution to rescue the history of development of the application of 99mTc, widely used in nuclear medicine, to its use as tracer for the study of the transport of fine sediment in suspension, in water environment. It addresses the usefulness of its application in obtaining important parameters in environmental studies, illustrating them with some applications already performed and the results obtained. This kind of study, when associated with information on hydrodynamic parameters, for example, river, tidal, wind and wave currents, are powerful tools for the understanding and quantification of fine sediment transport in suspension. Fine sediment is an important vector in the transportation of heavy metals, organic matter and nutrients in water environment, and the quantitative knowledge of its behaviour is mandatory for studies of environmental impacts. Fine sediment labelled with 99mTc, can also be used to study the effect of human interventions, such as dredging of reservoirs, access channels and harbours, and the dumping of dredged materials in water bodies. Besides that, it can be used to optimize dredging works, evaluating the technical and economic feasibility of dumping sites and their environmental impact. It is a valuable support in the calibration and validation of mathematical models for sediment dynamics.

The study investigated the effect of loci-kit models on students’ academic performance in technical drawing in Edo State technical colleges using non-equivalent control group quasi-experimental research design. Two research questions and two null hypotheses guided the study. The population for this study consisted of 864 vocational II students from the six technical colleges in Edo State. The sample for the study comprised of 110 (60 males and 50 females) randomly selected from all the technical colleges in Edo State. The instrument for data collection was Technical Drawing Achievement Test (TDAT). Three experts validated the instrument. The reliability of the instrument was determined using Kuder Richardson 21 (KR-21) formulae and a reliability coefficient of .85 was obtained. The research questions were answered using Mean and standard deviation while Analysis of Covariance (ANCOVA) was used to test the hypotheses at .05 level of significance. Findings from the study revealed that Loci-kit model was effective in enhancing technical college students’ performance in technical drawing topic loci; there was no significant mean effect of gender on students’ Mean performance score in Technical Drawing. In line with the findings of the study, it was recommended among others that Technical Drawing teachers should employ innovative approaches such as loci-kit models during instructions of loci concepts in technical drawing to facilitate students’ academic performance in the subject.

Abstract The main object of interest was a typical fuel assembly, which constitutes a core of the nuclear reactor. The aim of the paper is to describe the phenomena and calculate thermal-hydraulic characteristic parameters in the fuel assembly for a European Pressurized Reactor (EPR). To perform thermal-hydraulic calculations, the RELAP5 code was used. This code allows to simulate steady and transient states for reactor applications. It is also an appropriate calculation tool in the event of a loss-of-coolant accident in light water reactors. The fuel assembly model with nodalization in the RELAP5 (Reactor Excursion and Leak Analysis Program) code was presented. The calculations of two steady states for the fuel assembly were performed: the nominal steady-state conditions and the coolant flow rate decreased to 60% of the nominal EPR flow rate. The calculation for one transient state for a linearly decreasing flow rate of coolant was simulated until a new level was stabilized and SCRAM occurred. To check the correctness of the obtained results, the authors compared them against the reactor technical documentation available in the bibliography. The obtained results concerning steady states nearly match the design data. The hypothetical transient showed the importance of the need for correct cooling in the reactor during occurrences exceeding normal operation. The performed analysis indicated consequences of the coolant flow rate limitations during the reactor operation.

One of the strongest relationships among the elements of Heskett, Sasser and Schlesinger's service profit chain is verified between employee satisfaction and client's satisfaction. This paper reports the results of an exploratory study on the Brazilian operation of a world-wide leader of elevator technical assistance, in which the relationship between these two elements and their influence on the client retention rate was evaluated. The research data were treated with statistical discriminant and cluster analysis. The findings identified the relationship between employee and client satisfaction in 25 of the 27 business units studied. On the other hand, the factor that largely influences the client retention rate in this business environment is client satisfaction, while employee satisfaction is almost null. The results have important academic and managerial implications, given the limited amount of studies in this area and drive actions for the business success.

Maize constitute dominant food crop in upland semi-arid region of East Nusa Tenggara (ENT) and as a main staple for majority of rural farmers. This paper examines Provincial Government programs to increase maize production and to reform maize production orientation. Data and information being used from the recent program: “Maize Planting, Cattle Harvest (MPCH)”. The survey was conducted in all villages in Districts of Timor and Sumba Island as pilot project. The study showed that: 1). Maize farmers keen to change production orientation from subsistence to semi and fully commercial as long as there are surplus production and better access to the market, 2). Average maize productivity of farmers under program (5 – 8 ton/ha) higher than traditional practices (1 – 2 ton/ha), 3). Most farmers under the program have access to have own cattle 1- 2 head/household from surplus production of maize sold with contract price IDR 3,200/kg. This result implies that incorporated farmer into the market from the beginning of the program, technical assistance to apply appropriate innovations, organized farmers groups to enhance business scale and government support to minimize production cost lead farmers to adopt new innovation, increase maize production and change maize production orientation (commercial).

Instructional supervision in schools in general and technical colleges in particular is a precursor to goal attainment. This study focused on enhancing effective instructional supervision in Ogun State technical colleges. Being a descriptive research of the survey type, the study raised two research questions focusing on activities for enhancing effective instructional supervision in technical colleges and mechanisms for enhancing effective instructional supervision in technical colleges. Also, two null hypotheses tested at 0.05 significant level were formulated. The instrument developed and used for the study was the Effective Instructional Supervision Questionnaire (EISQ). The EISQ contained 22 items which was validated by three experts, and tested to obtain 0.92 reliability coefficient using Cronbach Alpha method. The EISQ was used for collecting data from 21 respondents made of technical college administrators in Ogun State. The data collected were descriptively analyzed using mean for the raised research questions and inferential statistics of t-test for the formulated hypotheses. The study recognized the potency of instructional supervision and the need for embracing it in Ogun State technical colleges. The study recommended that technical college administrators should ensure effective instructional supervision in Ogun State technical colleges for overt instructional improvement and as well adopt global best practices to ensure that teachers are motivationally carried along in instructional supervision activities.

Full textAbstract:
The poor academic achievement of students in technical colleges in Nigeria has been a major concern to researchers. It is believed that the application of effective instructional methods in technical colleges could enhance overall students’ academic achievement. This demands that teachers in technical colleges should adopt instructional methods that could enhance overall achievement particularly in students’ psychomotor, problem solving achievement and enhance retention in mechanical engineering craft practice in technical colleges. The study investigated the effectiveness of constructivism instructional method on students’ psychomotor achievement, problem-solving and retention in mechanical engineering craft practice in technical colleges in Delta State. Three research questions guided the study and three null hypotheses were tested at 0.05 level of significance. The study adopted the quasi-experimental research design. Population of the study was 97 vocational II mechanical engineering craft practice (MECP) students in the six technical colleges in Delta State. A sample of 82 was used for the study. Instruments for data collection were Mechanical Engineering Craft Practice Achievement Test (MECPAT) and the lesson plans for the experimental and control groups. The instruments- MECPAT and lesson plans; were face and content validated by three experts, two from the Department of Technology and Vocational Education and one from Measurement and Evaluation Unit of the Department of Educational Foundation; all in Nnamdi Azikiwe University Awka. Test–retest method was used to establish reliability of MECPAT and was calculated using Pearson Product Moment Correlation which yielded a correlation coefficient value of 0.87. Arithmetic mean was used to analyze data relating to research questions and while analysis of covariance (ANCOVA) was used to test the null hypotheses. Findings revealed that students taught mechanical engineering craft practice using constructivism instructional method performed better, possessed requisite problem solving skills and had better knowledge retention than those taught with lecture teaching method (LTD). Based on the findings, it was concluded that constructivism instructional teaching method (CITM) is an effective and efficient mode of instruction with capacity of improving students’ learning outcome, problem solving techniques and retention ability level. Consequently, it was recommended among others that technical teachers should use constructivism instructional method in teaching mechanical engineering craft practice so as to enhance students’ psychomotor achievement in subsequent public examination.

AbstractThe new radiation protection law in Germany, which came into effect 2018, puts greater emphasis on the protection against naturally occurring radiation, especially radon as a known health hazard. The law requires the delineation of radon priority areas, where prevention and remediation of high indoor radon concentrations should be taken with priority. In Germany, radiation protection is the administrative responsibility of the federal states. The state of Hesse has early on decided to fully survey the state for radon priority areas. To identify radon priority areas, the geogenic radon potential has to be determined. To achieve that radon, soil-gas measurements combined with soil permeability are a necessity. The University of Applied Sciences (THM) in Giessen is responsible for the radon soil-gas measurement campaign in Hessen. To achieve a statistically sound survey of the state of Hessen with an achievable amount of different measurement locations, and in the given time-frame, a geology-based concept has been designed. Taking into account the known geological information about geological structures in combination with the administrative counties, a survey strategy has been established. Prior known information regarding soil thickness, moisture, digability, and other technical limitations are used to determine the exact measuring locations. At every location, the radon activity in soil gas is measured. The soil permeability is determined for every measurement as well. Three measurements are performed at each location. Having completed the first set of measurements, the design criteria of the campaign and the practical experiences will be presented.

AbstractX-rays application for radiation processing was introduced to the industrial practice, and in some circumstances is found to be more economically competitive, and offer more flexibility than gamma sources. Recent progress in high-power accelerators development gives opportunity to construct and apply reliable high-power electron beam to X-rays converters for the industrial application. The efficiency of the conversion process depends mainly on electron energy and atomic number of the target material, as it was determined in theoretical predictions and confirmed experimentally. However, the lower price of low-energy direct accelerators and their higher electrical efficiency may also have certain influence on process economy. There are number of auxiliary parameters that can effectively change the economical results of the process. The most important ones are as follows: average beam power level, spare part cost, and optimal shape of electron beam and electron beam utilization efficiency. All these parameters and related expenses may affect the unit cost of radiation facility operation and have a significant influence on X-ray process economy. The optimization of X-rays converter construction is also important, but it does not depend on the type of accelerator. The article discusses the economy of radiation processing with high-intensity of X-rays stream emitted by conversion of electron beams accelerated in direct accelerator (electron energy 2.5 MeV) and resonant accelerators (electron energy 5 MeV and 7.5 MeV). The evaluation and comparison of the costs of alternative technical solutions were included to estimate the unit cost of X-rays facility operation for average beam power 100 kW.

Abstract An automatic control system is one of the most important parts of an irradiation facility. The level of this control is always maintained to comply with safety procedures during routine work in this field. Also sometimes it is limited to the minimum level of regulation required due to economical aspects; some commercial systems are generally made by manufacturers of industrial facilities and considered affordable by irradiators. In some cases specific irradiation facilities tailor their control systems to their needs. For this kind of irradiator the control system can be developed and upgraded according to personal and industrial experiences. These upgrading procedures are also used by others to develop their systems. The objective of this paper is to share a local experience in upgrading security, safety systems and the use of cobalt-60 for the irradiator. It is a composite experiment at SIBO INRA/Tangier, Morocco and concerns the: (i) upgrade of cobalt-60 in a temporary pool in the SIBO irradiator in Tangier. This operation was conducted in collaboration with the International Atomic Energy Agency (IAEA) and was a success story of 2014 according to the general conference of IAEA; (ii) safety and technical upgrade of the system in the SIBO irradiator made in collaboration with IAEA; (iii) installation and upgrade of the security system in accordance with the Global Threat Reduction Programme (GTRP) to reduce the threat of a Radiological Dispersal Device (RDD) in collaboration with The United States Department of Energy’s National Nuclear Security Administration (NNSA).

Full textAbstract:
Abstract The paper presents comparison of two silicon drift detectors (SDD), one made by Amptek, USA, and the second one by PNDetector, Germany, which are considered for a soft X-ray diagnostic system for W7-X. The sensitive area of the first one is 7 mm2 × 450 μm and the second one is 10 mm2 × 450 μm. The first detector is cooled by a double-stage Peltier element, while the second detector is cooled by single-stage Peltier element. Each one is equipped with a field-effect transistor (FET). In the detector from Amptek, the FET is mounted separately, while in the detector from PNDetector, the FET is integrated on the chip. The nominal energy resolution given by the producers of the first and the second one is 136 eV@5.9 keV (at -50°C) and 132 eV@5.9 keV (at -20°C), respectively. Owing to many advantages, the investigated detectors are good candidates for soft X-ray measurements in magnetic confinement devices. They are suitable for soft X-ray diagnostics, like the pulse height analysis (PHA) system for the stellarator Wendelstein 7-X, which has been developed and manufactured at the Institute of Plasma Physics and Laser Microfusion (IPPLM), Warsaw, in collaboration with the Max Planck Institute for Plasma Physics (IPP), Greifswald. The diagnostic is important for the measurements of plasma electron temperature, impurities content, and possible suprathermal tails in the spectra. In order to choose the best type of detector, analysis of technical parameters and laboratory tests were done. Detailed studies show that the most suitable detector for the PHA diagnostics is the PNDetector.

Following myocardial infarction (MI), matrix metalloproteinase-9 (MMP-9) levels increase, and MMP-9 deletion improves post-MI remodeling of the left ventricle (LV). We provide here a technical report on plasma-analysis from wild type (WT) and MMP-9 null mice using fractionation and mass-spectrometry-based proteomics. MI was induced by coronary artery ligation in male WT and MMP-9 null mice (4–8 months old; n=3/genotype). Plasma was collected on days 0 (pre-) and 1 post-MI. Plasma proteins were fractionated and proteins in the lowest (fraction 1) and highest (fraction 12) molecular weight fractions were separated by 1-D SDS-PAGE, digested in-gel with trypsin and analyzed by HPLC-ESI-MS/MS on an Orbitrap Velos. We tried five different fractionation protocols, before reaching an optimized protocol that allowed us to identify over 100 proteins. Serum amyloid A substantially increased post-MI in both genotypes, while alpha-2 macroglobulin increased only in the null samples. In fraction 12, extracellular matrix proteins were observed only post-MI. Interestingly, fibronectin-1, a substrate of MMP-9, was identified at both day 0 and day 1 post-MI in the MMP-9 null mice but was only identified post-MI in the WT mice. In conclusion, plasma fractionation offers an improved depletion-free method to evaluate plasma changes following MI.

Full textAbstract:
Abstract The concept of closed nuclear fuel cycle seems to be the most promising options for the efficient usage of the nuclear energy resources. However, it can be implemented only in fast breeder reactors of the IVth generation, which are characterized by the fast neutron spectrum. The lead-cooled fast reactor (LFR) was defined and studied on the level of technical design in order to demonstrate its performance and reliability within the European collaboration on ELSY (European Lead-cooled System) and LEADER (Lead-cooled European Advanced Demonstration Reactor) projects. It has been demonstrated that LFR meets the requirements of the closed nuclear fuel cycle, where plutonium and minor actinides (MA) are recycled for reuse, thereby producing no MA waste. In this study, the most promising option was realized when entire Pu + MA material is fully recycled to produce a new batch of fuel without partitioning. This is the concept of a fuel cycle which asymptotically tends to the adiabatic equilibrium, where the concentrations of plutonium and MA at the beginning of the cycle are restored in the subsequent cycle in the combined process of fuel transmutation and cooling, removal of fission products (FPs), and admixture of depleted uranium. In this way, generation of nuclear waste containing radioactive plutonium and MA can be eliminated. The paper shows methodology applied to the LFR equilibrium fuel cycle assessment, which was developed for the Monte Carlo continuous energy burnup (MCB) code, equipped with enhanced modules for material processing and fuel handling. The numerical analysis of the reactor core concerns multiple recycling and recovery of long-lived nuclides and their influence on safety parameters. The paper also presents a general concept of the novel IVth generation breeder reactor with equilibrium fuel and its future role in the management of MA.

Full textAbstract:
Two models of technical inefficiency with a stochastic production frontier are considered in this paper. In the frrst model, it is assumed that the frontier itself does not vary with time, while in the second, the frontier is allowed to move. These models are applied to four years of panel data on wheat farmers in four districts of Pakistan: Faisalabad and Attock in the Punjab, Badin in Sindh, and Dir in the NWFP. Using essentially the same stochastic frontier production function in each of the four districts involved, different stochastic specifications for the inefficiency effects are obtained for the different districts. Technical efficiencies of production of the individual farmers are predicted in each year in which they are observed. Varying patterns of technical inefficiency are observed. The null hypothesis (of no technical inefficiency) cannot be rejected in only one district. In the other districts, while inefficiencies appear to be present in all of them, they are declining at a fairly rapid pace in one. The results highlight the importance of analysis at a disaggregated level because it is clear that both the rate of technical change and relative efficiencies vary across regions and explicit cognisance must be taken of this both in research and policy formulation.

Full textAbstract:
This article aims at the characterization of specific features of translated texts. Taking a classroom experience as its starting point, the use of anglicisms in original and translated computing texts in Italian is examined. The corpus used for this purpose has three components: originals in Italian, comparable translations into Italian, and their English source texts. The frequency of three sets of English words – overt lexical borrowings, adapted borrowings and semantic loans, and morphosyntactic calques (plurals ending in –s) – is compared across the monolingual comparable subcorpus components. The parallel subcorpus is then checked to disprove the null hypothesis according to which observed differences are unrelated to the translation process. The results of the quantitative analysis, followed by careful qualitative observations, confirms that translators are more conservative in their choices and normalize more than writers, who seem to be more prone to interference from English as the lingua franca of the IT discourse community. Implications at the methodological, descriptive/theoretical and applied levels are discussed.

We consider the finite-time stabilization of homogeneous quasilinear hyperbolic systems with one side controls and with nonlinear boundary condition at the other side. We present time-independent feedbacks leading to the finite-time stabilization in any time larger than the optimal time for the null controllability of the linearized system if the initial condition is sufficiently small. One of the key technical points is to establish the local well-posedness of quasilinear hyperbolic systems with nonlinear, non-local boundary conditions.

Potato cultivation accounts for 5.71 percent in total cropped area of the Punjab province and it supplements the diet of the growing population at lower prices as compared to grains, meat and chicken. Data from 100 farmers, 50 each from the districts of Okara and Kasur during the year 2002-2003 (the autumn crop) has been collected. The study estimates the technical efficiency in potato production by employing the Cobb-Douglas stochastic production frontier approach. The null hypothesis of no technical inefficiency in the data is rejected. Our results indicate that potato farmers are 84 percent technically efficient, implying significant potential in potato production that can be developed. By shifting the average farmer to the production frontier, the average yield would increase from 8.33 tons per acre to 9.92 tons per acre using the available resources. The additional quantity of potatoes gathered through efficiency improvements would generate Rs. 990.81 ($16.51) million of revenue each year. Consultation with extension workers significantly contributes to the improvement of technical efficiency and implies that the extension department should be one of the major targeted variables from the policy point of view in order to improve technical efficiency in potato production.

Uncertainty is inherent to science and science communication. However, the evidence appears mixed regarding whether portraying uncertainty in science communication has positive or negative effects. We review a diverse range of experimental literature ( k = 48; from 40 searches and 8000 retrievals), summarize the extant findings, and observe how the effects vary across four different types of communicated uncertainty ( deficient, technical, scientific, and consensus uncertainty). The results indicate that most findings of negative effects (such as reduced credibility and beliefs) are from experiments that operationalized uncertainty as disagreement or conflict in science ( consensus uncertainty). In this review, consensus uncertainty was never found to have positive effects. In contrast, uncertainty in the form of quantified error ranges and probabilities ( technical uncertainty) in these studies has had only positive or null effects, not negative effects. We also highlight frequent moderators of the effects of uncertainty, such as prior beliefs and worldviews.

In a context of unregulated practice, strategic environmental assessment (SEA) contribution to environmentally sound decision-making may be difficult to gauge. Recent Brazilian experience, where there is no legal requirement for SEA, was studied by reviewing cases selected by considering distinctive drivers for undertaking an assessment, varied locations and different consultancies hired to prepare the report. A quality review checklist was used to evaluate the contents of SEA reports according to: (i) adherence to good practice; (ii) technical quality and adequacy to decision-making processes; (iii) achievement of sound and enduring environmental benefits. Interviews aimed at gauging their actual influence. SEAs reached a relatively high level of technical quality and procedural effectiveness, but very low substantive effectiveness. Influence on decision-making varied from null to limited consideration of information in developing programs. The main challenge for SEA in unregulated contexts is to demonstrate its value to decision-makers and citizens' organisations.

Two experts from the Department of Industrial Technical Education, University of Nigeria, Nsukka, and one expert from Anambra Motor Manufacturing Company (ANAMCO) face validated the instrument. The reliability co-efficient of the instrument was found to be 0.87 using Cronbach Alpha. Data collected were analyzed using mean and standard deviation for the research questions, while t-test was used to test the null hypotheses. The results of the study indicate that that automobile craftsmen find difficulties in servicing some automobile mechatronics sub-systems, while 16 mechatronics sub-systems were agreed on to be integrated into the automobile curriculum. It was recommended that these mechatronics sub-systems should be integrated into technical college curriculum and that technical colleges should partner with automobile industries for effective training of craftsmen. The study will contribute positively to the understanding of automobile mechatronics technology, and how it can be integrated into the curriculum.

AbstractApplying microsatellite DNA markers in population genetic studies of the pest mothHelicoverpa armigerais subject to numerous technical problems, such as the high frequency of null alleles, occurrence of size homoplasy, presence of multiple copies of flanking sequence in the genome and the lack of PCR amplification robustness between populations. To overcome these difficulties, we developed exon-primed intron-crossing (EPIC) nuclear DNA markers forH. armigerabased on ribosomal protein (Rp) and the Dopa Decarboxylase (DDC) genes and sequenced alleles showing length polymorphisms. Allele length polymorphisms were usually from random indels (insertions or deletions) within introns, although variation of short dinucleotide DNA repeat units was also detected. Mapping crosses demonstrated Mendelian inheritance patterns for these EPIC markers and the absence of both null alleles and allele ‘dropouts’. Three examples of allele size homoplasies due to indels were detected in EPIC markers RpL3, RpS6 and DDC, while sequencing of multiple individuals across 11 randomly selected alleles did not detect indel size homoplasies. The robustness of the EPIC-PCR markers was demonstrated by PCR amplification in the related species,H. zea,H. assultaandH. punctigera.

Abstract. The U.S. Geological Survey (USGS) Geomagnetism Program has developed and tested the residual method of absolutes, with the assistance of the Danish Technical University's (DTU) Geomagnetism Program. Three years of testing were performed at College Magnetic Observatory (CMO), Fairbanks, Alaska, to compare the residual method with the null method. Results show that the two methods compare very well with each other and both sets of baseline data were used to process the 2015 definitive data. The residual method will be implemented at the other USGS high-latitude geomagnetic observatories in the summer of 2017 and 2018.

Full textAbstract:
The level of yield among sweet potato farmers is on a decline; low output and yield differences was observed, indicating the existence of inefficiency in production systems and variations in input utilization. Efficiency in resource use must be sustained in order to improve productivity and maximize farm output. This study therefore analyzed the technical efficiency of sweet potato production. Multi-stage sampling techniques were adopted in selecting 94 respondents for this study. Data collected was analyzed using descriptive statistics and stochastic frontier production function. The socioeconomic variables of the respondents affected their farm efficiency and level of farm output. The estimated ratio of the L/R test was 0.579; indicating a goodness of fit of the frontier model and thus a rejection of the null hypothesis. The coefficients of sweet potato seeds (vines) (0.362) and labour (0.439) were positive and statistically significant at 5% level of probability, while the coefficients of farm size (-1.333), fertilizer (-0.452) and herbicides (-0.766) were negative but statistically significant at 5% level of probability. The inefficiency model revealed that the coefficient of farm capital (-0.172), education (-2.281), access to credit (-0.472), farming experience (-0.639), extension contact (-0.733) and membership of cooperatives (-0.396) were negative and statistically significant at 5% level of probability. The mean technical efficiency was 0.62 (62%) implying that the sweet potato farmers in the study area were not producing at optimal capacity. The constraints identified significantly affected sweet potato production in the study area. Subsidizing input costs; sensitizing farmers on appropriate farming practices, cooperative formation and efficiency in resource utilization; improving access to agricultural inputs, technology, farm capital, credit and extension services, market linkages, farm labour supply and the development of indigenous technologies in sweet potato production are strongly recommended.

Full textAbstract:
The technical difficulties of performing underwater observation mean that marine ecologists have long relied on behavioural experiments to study reactions of marine organisms. In this article, we examine the underlying complexity of assumptions made in raceway experiments and we propose a statistical inference procedure tailored to this type of experimental protocol. As an example, experiments were performed to test if light of two different intensities affects the proximal behaviour (i.e. direct, local and immediate) of two species of crustaceans, the hermit crab (Pagurus bernhardus), and the green crab (Carcinus maenas). Individuals were collected in the vicinity of the Sven Loven Marine Center in Tjarnö (Sweden). Their movements in raceways were recorded and the statistical distance between the resulting experimental distribution and a simulated null distribution was used to compare their behaviour in two situations: dim (when they were expected to feed) and bright light (when they were expected to shelter). Initial tests indicated no differences of behaviour between dim and bright light for the two species. However, when compared with the reference state (here, a null distribution) the behaviour in dim light deviates significantly from the null distribution suggesting non-random behaviour. Our results suggest that efforts should be made to understand the behaviours of the individuals of these two species to establish a comprehensive reference state as a basis for comparison. This fundamental information should be a prerequisite before implementing experiments testing how potential disturbances affect individual organisms in behavioural ecology.

Liang Ndara village is one of the village in Mbeliling sub-district, West Manggarai regency, Flores of East Nusa Tenggara Province. Liang Ndara village has many tourism potentials specifically regarding to the ecotourism. Free entrance fee in to those tourism places caused by unserious and less attention of the government are becoming problem, as well as Lack of human resources of people is another problem causing the potentials are not well organized yet and even it is not in a good tourism packaging. The research aim to find out the tourism potential that can be made ecotourism packages and packaging them to become an ecotourism in Liang Ndara village. The data collection of this research is by an observation, documentation, interviewing and as well as literature. The data analysis technic used is by analysis technic of qualitative descriptive. The results of this research showed that Liang Ndara village has three kinds of tourism potential which is in a packaging of ecotourism. Those potentials are the natural tourism potentials consist of Mbeliling Mountain, Cunca rami waterfall, Cunca Wae Kantor waterfall and Liang Niki Cave. The cultural tourism potentials are Caci dance, Compang Kafir Stone, Compang Serani statue, Batu Tiga, Hand Weaving of Songke, Farming Activities such as sopi/arak filtration, cultivating of rice field. Man made tourism potentials are information center in the village, guest house, and souvenir shops. The potentials above are packaged in to two kind of ecotourism packages they are Liang Ndara Village Tour and Mbeliling Green Forest Tour. The suggestions are the government is supposed to put their eyes on to develop those potential exist and need to be hand in hand with the tourism actors as well as the society. The travel agencies are expected to make an interesting tourism package like ecotourism and also supposed to be together with the society to take care and survive the tourism potentials existed.
