description: The evaluation of technical efficiency of production has been a major issue of interest for economists since the 1950's. One of useful methods in that respect is Data Envelopment Analysis (DEA) which facilitates estimation of production efficiency based on results obtained by a specific set of economic entities. The aim of this study is to analyze dynamics of changes in technical efficiency of production in the agricultural sector of the European Union (EU), including four basic production factors, i.e. labour, land, fixed capital and working capital. For the evaluation of efficiency, the DEA method was applied with reference to the economic output generated in the period of 1989-2007 by average farms representative for selected EU regions. Efficiency values estimated in this way constituted a basis for the determination of efficiency changes in time, which in turn made it possible to identify differences in production technology in particular countries or groups of countries. These considerations were supplemented with a discussion based on the classical analysis of utilization of basic production factors in agriculture. / Synopsis. Ocena technicznej efektywności produkcji jest jednym z ważniejszych zagadnień wzbudzających zainteresowanie ekonomistów od połowy ubiegłego wieku. Jedną z metod przydatnych w tym zakresie jest Data Envelopment Analysis (DEA), pozwalająca na oszacowanie efektywności produkcji w oparciu o wyniki osiągane przez ustalony zbiór jednostek gospodarczych. Celem niniejszej pracy jest analiza dynamiki zmian technicznej efektywności produkcji w sektorze rolnictwa Unii Europejskiej (UE) z uwzględnieniem czterech podstawowych czynników produkcji, tj. pracy, ziemi, kapitału trwałego i kapitału obrotowego. Dla oceny efektywności zastosowano analizę DEA w odniesieniu do wyników ekonomicznych osiągniętych w latach 1989-2007 przez przeciętne gospodarstwa reprezentujące wybrane regiony UE. Uzyskane przeciętne techniczne efektywności w kolejnych latach badanego okresu dają podstawę dla wyznaczenia zmian efektywności w czasie, które z kolei pozwalają na uchwycenie różnic technologii produkcji na poziomie poszczególnych krajów lub ich grup. Rozważania te uzupełnia dyskusja oparta na klasycznej analizie wykorzystania podstawowych czynników produkcji rolniczej.

description: The purpose of the paper was to point out causations and changes concerning fruit and vegetable quality in the domestic market. For this end attention was paid to legal aspects of assuring fruit and vegetable quality in the European Union market. Results of commercial and health quality of fruit and vegetable were analyzed. The research has shown that domestic fruit and vegetable are safe for consumer’s health. Contents of toxic elements in fruit and vegetable, except for singular cases, are consistent with standing legal regulations. Commercial quality of domestic fruit destined for fresh consumption, due to detected irregularities concerning the consistency with the binding norms, requires permanent supervisions from the part of the authorized controlling organs. / Synopsis. Zamierzeniem pracy było wskazanie uwarunkowań i zmian w zakresie jakości owoców i warzyw na rynku krajowym. W tym celu zwrócono uwagę na aspekty prawne zapewnienia jakości owoców i warzyw na rynku wspólnotowym oraz przeanalizowano wyniki urzędowego nadzoru jakości handlowej i zdrowotnej owoców i warzyw. Przeprowadzone analizy wskazują, że krajowe owoce i warzywa są bezpieczne dla zdrowia konsumentów. Zawartość pierwiastków toksycznych w owocach i warzywach jest, poza nielicznymi wyjątkami, zgodna z obowiązującymi regulacjami prawnymi. Jakość handlowa owoców krajowych przeznaczonych do spożycia w stanie świeżym, w związku z wykrywanymi nieprawidłowościami w zakresie zgodności z obowiązującymi normami, wymaga stałego nadzoru ze strony upoważnionych organów.

description: Within the framework of the molecular dynamics method, the mechanical behavior of a graphene nanoinclusion in a matrix of zirconium dioxide stabilized by yttrium oxide has been simulated. The analysis of the possibility of using the existing interatomic interaction potentials developed for these crystals in model mechanical tests of the nanocomposite is carried out. It is shown that pristine graphene is an excellent reinforcing element of the composite, since it is deformed without the formation of defects in the range of small and medium strain values. The artificial creation of small pores of 3 Å in diameter in the intermediate layers also makes little effect on the destruction of the graphene nanoinclusion. The creation of pores of 5 Å in diameter and more can lead to cracking of the nanoinclusion. To improve the accuracy of the model and to observe the destruction of the sample under study, the need to develop a new potential for interatomic interaction is demonstrated

description: The disorder and layer transitions in the interface between an Ising spin-1/2 film denoted $(n)$, and an Ising spin-1 film denoted $(m)$, are studied using Monte Carlo simulations. The effects of both an external magnetic field, acting only on the spin-1/2 film, and a crystal magnetic field acting only on the spin-1 film, are studied for a fixed temperature and selected values of the coupling constant $J_p$ between the two films. It is found that for large values of the constant $J_p$, the layers of the film $(n)$, as well as those of the film $(m)$, undergo a first order layering transition. On the other hand, the only disordered layer of the film $(n)$ is that one belonging to the interface films $(n)/(m)$, for any values of the crystal field $Δ$. We show the existence of a critical value of the crystal field $Δ_c$, above which this particular layer of the film $(n)$ is disordered. We found that $Δ_c$ depends on the values of the constant coupling $(J_p)$ between the two films.

description: Despite the remarkable advancements in Visual Question Answering (VQA), the challenge of mitigating the language bias introduced by textual information remains unresolved. Previous approaches capture language bias from a coarse-grained perspective. However, the finer-grained information within a sentence, such as context and keywords, can result in different biases. Due to the ignorance of fine-grained information, most existing methods fail to sufficiently capture language bias. In this paper, we propose a novel causal intervention training scheme named CIBi to eliminate language bias from a finer-grained perspective. Specifically, we divide the language bias into context bias and keyword bias. We employ causal intervention and contrastive learning to eliminate context bias and improve the multi-modal representation. Additionally, we design a new question-only branch based on counterfactual generation to distill and eliminate keyword bias. Experimental results illustrate that CIBi is applicable to various VQA models, yielding competitive performance.

description: Development of experimental techniques to study superfluid dynamics, in particular, application of nanomechanical oscillators to drive vortex lines, enables potential observation of the Kelvin-wave cascade on quantized vortices. One of the first questions which then arises in analysis of the experimental results is the relation between the energy flux in the cascade and the amplitude of the Kelvin waves. We provide such relation based on the L'vov-Nazarenko picture of the cascade. Remarkably, the amplitude of the waves depends on the energy flux extermely weakly, as power one tenth.

description: Two quantum spin models with bilinear-biquadratic exchange interactions are constructed on the checkerboard lattice. It is proved that, under certain sufficient conditions on the exchange parameters, their ground states consist of two degenerate Shastry-Sutherland singlet configurations. The constructions are studied for arbitrary spin-S. The sufficient conditions for the existence of ferromagnetic ground state are also found exactly. The approximate quantum phase diagrams are presented using the exact results, together with a variational estimate for the Néel antiferromagnetic phase. A two-leg spin-1/2 ladder model, based on one of the above constructions, is considered which admits exact solution for a large number of eigenstates. The ladder model is shown to have exact level-crossing between the rung-singlet state and the AKLT state in the singlet ground state. Also introduced is the notion of perpendicularity for quantum spin vectors, which appears in the discussion on one of the two checkerboard models, and is discussed in the Appendix.

description: Recent results from the KASCADE experiment on measurements of cosmic rays in the energy range of the knee are presented. Emphasis is placed on energy spectra of individual mass groups as obtained from an two-dimensional unfolding applied to the reconstructed electron and truncated muon numbers of each individual EAS. The data show a knee-like structure in the energy spectra of light primaries (p, He, C) and an increasing dominance of heavy ones (A > 20) towards higher energies. This basic result is robust against uncertainties of the applied interaction models QGSJET and SIBYLL which are used in the shower simulations to analyse the data. Slight differences observed between experimental data and EAS simulations provide important clues for further improvements of the interaction models. The data are complemented by new limits on global anisotropies in the arrival directions of CRs and by upper limits on point sources. Astrophysical implications for discriminating models of maximum acceleration energy vs galactic diffusion/drift models of the knee are discussed based on this data.

description: We discuss lepton flavour violating signals at the LHC in the framework of supersymmetric theories. We consider R-parity conserving as well as R-parity violating scenarios. In the case of R-parity conservation we show that in decays of supersymmetric particles large regions in parameter exist where lepton flavour violating decay modes have large branching ratios despite the stringent constraints from the non-observation of rare lepton decays. We discuss briefly some consequences for discovery potential and the measurements of edge-variables at LHC within the SPS1a scenario. In the case of R-parity violating scenarios we focus on bilinear R-parity violation. We discuss correlations between the decays of the lightest neutralino and neutrino mixing angles as well as the possibilities to measure these correlations at LHC.

description: The aim of the paper is to present and analyse the most important undertakings in the sphere of market creation for the renewable energy produced in Poland from agricultural products. The demand for such energy is created as a result of legal regulations, which obligate the energy sector entities to evidence an adequate share of renewable energy and biofuels in their deliveries. This supply development is achieved due to support systems addressed to energy and agricultural sectors entities. The readiness of enterprises and local territorial authorities to undertake the adequate investment is yet comparatively small. In order to meet the needs for agricultural sources of energy production in Poland, about 4 million hectare of farm lands should be put into their cultivation till 2020. / Synopsis. Celem artykułu jest przedstawienie i analiza najważniejszych przedsięwzięć w sferze tworzenia rynku energii odnawialnej wytwarzanej w Polsce na bazie wykorzystania produktów rolniczych. Popyt na taką energię powstaje wskutek regulacji prawnych, które zobowiązują podmioty sektora energetycznego do posiadania energii odnawialnej i biopaliw w strukturze dostaw. Rozwój podaży osiąga się dzięki mechanizmom wsparcia adresowanym do podmiotów z sektora energii i sektora rolnictwa. Gotowość przedsiębiorstw i jednostek samorządu terytorialnego do podejmowania inwestycji jest jeszcze stosunkowo mała. Na cele wytwarzania energii z produktów rolnictwa trzeba będzie w Polsce przeznaczyć do roku 2020 około 4 mln ha ziem uprawnych.

description: Sample pooling consists in combining samples from multiple individuals into a single pool that is then tested using a unique test-kit. A positive test means that at least one individual within the pool is infected. Here, we propose an analysis and applications of sample pooling to the epidemiologic monitoring of COVID-19. We first introduce a model of the RT-qPCR process used to test for the presence of virus in a sample and construct a statistical model for the viral load in a typical infected individual inspired by the clinical data from Jones et. al. (2020). We then propose a method for the measure of the prevalence in a population, based on group testing, taking into account the increased number of false negatives associated with this method. Finally, we present an application of sample pooling for the prevention of epidemic outbreak in closed connected communities (e.g. nursing homes).

Documentation and gifted young children : a Reggio Emilia inspired study
Creators: name: Lee, Soyoung
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the present study was to understand what the roles of documentation for gifted young children are, and how educators perceive, assess and promote children's giftedness through documentation. A questionnaire and interviews were used to gather data from fourteen early childhood teachers who adopted the Reggio Emilia approach in their classes in North America. This study has resulted in a broad range of findings, among which are that documentation promotes gifted children to learn in depth by revisiting and remembering their work and by generating their interests. At the same time, teachers thought that documentation promotes gifted children's metacognitive skills and social interaction with peers. In addition, documentation appeared to take various roles for teachers. Teachers could be aware of children's capabilities, and prepare curriculum/projects for the next steps by observing, listening, and researching children's thoughts and ideas during the procedure of documentation. In terms of teachers' conceptions of giftedness in young children, teachers appeared to have various conceptions of giftedness rather than one common conception. Generally most of teachers in this study appeared to be aware of young gifted children. However, a few educators showed negative attitudes and definitions of giftedness which seemed to result in failure to identify gifted children and their characteristics in their class. This study suggests that documentation helps teachers to recognize children's potential, and to be ready for children's further learning; also in this way, gifted children can learn deeply, interacting with peers through documentation. Findings also show that, in order for this to occur, there is need for teachers to be open to young children's giftedness.

description: Das von dem Politikwissenschaftler Raul Hilberg (1926-2007) verfasste Werk "The Destruction of the European Jews", mit dessen ersten Kapiteln er 1955 an der Columbia University promoviert wurde und das nach langer Verlagssuche schließlich 1961 erschien, gilt heute als einer der wissenschaftlichen Meilensteine bei der systematischen Erforschung des nationalsozialistischen Völkermordes an den europäischen Juden. Im Kapitel X des Buches mit dem Titel "Reflections" präsentiert Hilberg die aus seinem intensiven Quellenstudium von Täterdokumenten hervorgegangenen Thesen von der Prozesshaftigkeit und der administrativen Struktur des Judenmordes. Anfang der 1960er Jahre übersetzte der Berliner Politikstudent Urs Müller-Plantenberg (*1937) dieses Kapitel aus der englischsprachigen Originalausgabe auf eigene Faust ins Deutsche und schickte die Übersetzung an verschiedene westdeutsche Verlagshäuser, um diese auf die Bedeutung des Werkes aufmerksam zu machen und eine vollständige deutsche Übersetzung und Publikation anzuregen. Müller-Plantenbergs Engagement blieb jedoch ohne Ergebnis. Das bislang unveröffentlichte 27seitige maschinenschriftliche Übersetzungsfragment aus dem Privatarchiv Müller-Plantenberg ist damit Teil der schwierigen Publikationsgeschichte des Hilberg-Buches in Deutschland und zeigt zugleich, dass die Anfänge der Holocaustforschung in Deutschland vom Engagement Einzelner ausgingen, die auf vielfältige gesellschaftliche Widerstände und auf Desinteresse in der jungen Bundesrepublik stießen. Erst gut zwei Jahrzehnte nach der Übersetzung des Mittzwanzigers Müller-Plantenberg brachte der Berliner Verlag Olle & Wolter unter dem Titel "Die Vernichtung der europäischen Juden" im Jahr 1982 eine deutsche Ausgabe des Hilberg'schen opus magnum heraus.

description: Egypt is considered one of the main producers of date fruits in the world. Tamr dry date is widely cultivated in Upper Egypt, however, investigating the chemical components and biological activities of such common variety has not been performed yet. In this study, the chemical components of the Tamr variety and its biological activities were investigated. Results showed that the percentages of sugar, dietary fibers, metal, protein were 61.0%, 13.7%, 2.1, and 2.6%, respectively. Total phenolic and flavonoids were 17.6 and 2.3 mg/100 g, respectively. 17 amino acids, 8 metals, 15 fatty acids, 30 terpenes, vitamins (A, B1, B2, B3), and 5 flavonoids were identified. The presence of phenolics and flavonoids in ethyl acetate extract resulted in high biological activity than chloroform and methanolic extracts. The biological activity of chloroform extract could be ascribed to the presence of polyunsaturated fatty acids and terpenes. These results are in good agreement with the chemical-biological relationships.

description: Improving students’ learning is dependent on students’ participation, meaningfulness, and value of the teaching– learning process. This study explores students’ learning experiences when undertaking the role of co-constructors and co- and self-regulators in a cooperative learning environment. Methods: The study included 110 school students aged between 15 and 18 years from four physical education preservice teachers’ classes. Data were collected through student focus group interviews, a postteaching units’ survey, students’ class reflections, and the researcher’s field notes. Results/Discussion: Data report that (a) having access to learning goals and assessment criteria was essential for the co-construction and co- and self-regulation processes, (b) there is a positive reciprocal relationship between students’ involvement in co-construction and co- and selfregulations, and (c) co-construction and co- and self-regulations were strengthened by students’ involvement in cooperative learning and vice versa.

description: The clonal propagation of T. cacao by somatic embryogenesis (SE) is a promising approach to multiply elite genotypes. Assessing clonal fidelity in plants regenerated from somatic embryos is the first step toward ensuring genetic uniformity in the mass production of planting material. This study assessed the genetic stability of cacao plantlets propagated by SE and conventional grafting for genotypes CCN51 and TSH565 using 13 SSR. The leaves of in vitro plantlets (IVL) were collected from 6-month-old plants and leaves of field plants (FPL) were selected from 3-year-old trees. The 13 analyzed loci revealed 25 alleles in genotype CCN51 and 24 alleles in genotype TSH565. The highest PIC value was observed for all SSR, only mTcCIR8 and mTcUNICAMP09 were intermediate, with PIC values of less than 0.250. IVL and FPL populations were genetically equal. According to the results, no differences in allelic composition were observed between FPL and IVL in each genotype. This indicates that plants propagated by SE did not show perceptible detriment to their genome with the used SSR. In addition, Jaccard’s coefficient showed more than a 91% similarity for TSH565 and 92% for CCN51. The UPGMA and PCA showed that the populations tended to group within two genotypes. The SSR results obtained do not exclude the occurrence of other changes in the nuclear genome. However, considering the morphological stability of in vitro propagated plants, the results indicate that the protocol used is suitable and efficient for large scale, true-to-type propagation of genotypes CCN51 and TSH565 for commercial purposes.

description: We present measurements of R_Kl3rad = Gamma(KL->π\ellνγ; Egcm > 10 MeV)/Gamma(KL->π\ellν), where ell = mu or e, and Egcm is the photon energy in the kaon rest frame. These measurements are based on KL decays collected in 1997 by the KTeV (E832) experiment at Fermilab. With samples of 1385 KL->πμνγand 14221 KL->π\eνγcandidates, we find R_Km3rad = (0.530 +- 0.019)% and R_Ke3rad = (4.942 +- 0.062)%. We also examine distributions of photon energy and lepton-photon angle.

A genomics study of Pinus taeda somatic embryo germination
Creators: name: Lane, Alexander
Publisher: name: University of British Columbia
Year: 2010

description: Loblolly pine (Pinus taeda) is one of the most prolific plantation forest tree species, and has significant ecological and economical importance. In order to maximize Pinus taeda plantation productivity, there has been extensive interest in developing an efficient vegetative reproduction system that could maximize production of elite performing trees, thereby minimizing the need for lengthy breeding cycles and dependence on traditional seed orchards. Somatic embryogenesis is one such propagation method that makes it possible to generate large numbers of genetically identical somatic embryos from a single zygotic seed. Though this technology is well established in research settings, the industrial application of this process has been limited due to low production efficiency. Germination of the somatic embryos has been one step in the process that appears to introduce a high degree of variability into the overall process. To better understand this variability a molecular level characterization of germinating somatic embryos was performed. By using cDNA microarray technology it was possible the plot the gene expression profiles of approximately 22000 genes across 3 time points and 4 growth medium treatments. Key primary and secondary biochemical pathways were observed to be induced while a large population of transcripts appears to be stored in the desiccated embryo prior to germination. The utility and challenges of cross-species microarray hybridizations are also discussed.

description: X-ray Flashes (XRFs) are, like Gamma-Ray Bursts (GRBs), thought to signal the collapse of massive stars in distant galaxies. Many models posit that the isotropic equivalent energies of XRFs are lower than those for GRBs, such that they are visible from a reduced range of distances when compared with GRBs. Here we present the results of two epoch Hubble Space Telescope imaging of two XRFs. These images taken approximately 45 and 200 days post burst reveal no evidence for an associated supernova in either case. Supernovae such as SN 1998bw would have been visible out to z ~1.5 in each case, while fainter supernovae such as SN 2002ap would have been visible to z ~ 1. If the XRFs lie at such large distances, their energies would not fit the observed correlation between the GRB peak energy and isotropic energy release, in which soft bursts are less energetic. We conclude that, should these XRFs reside at low redshifts ($z<0.6$), either their line of sight is heavily extinguished, or they are associated with extremely faint supernovae, or, unlike GRBs, these XRFs do not have temporally coincident supernovae.

The importance of 15O(a,g)19Ne to X-ray bursts and superbursts

description: One of the two breakout reactions from the hot CNOcycle is 15O(a,g)19Ne, which at low temperatures depends strongly on the resonance strength of the 4.033 MeV state in 19Ne. An experimental upper limit has been placed on its strength, but the lower limit on the resonance strength and thereby the astrophysical reaction rate is unconstrained experimentally. However, this breakout reaction is crucial to the thermonuclear runaway which causes type I X-ray bursts on accreting neutron stars. In this paper we exploit astronomical observations in an attempt to constrain the relevant nuclear physics and deduce a lower limit on the reaction rate. Our sensitivity study implies that if the rate were sufficiently small, accreting material would burn stably without bursts. The existence of type I X-ray bursts and superbursts consequently suggests a lower limit on the 15O(a,g)19Ne reaction rate at low temperatures.

description: The non-trivial magnetic and electronic phases occurring in topological magnets are often entangled, thus leading to a variety of exotic physical properties. Recently, the BaAl$_4$-type compounds have been extensively investigated to elucidate the topological features appearing in their real- and momentum spaces. In particular, the topological Hall effect and the spin textures, typical of the centrosymmetric Eu(Al,Ga)$_4$ family, have stimulated extensive experimental and theoretical research. In this topical review, we discuss the latest findings regarding the Eu(Al,Ga)$_4$ topological antiferromagnets and related materials, arising from a vast array of experimental techniques. We show that Eu(Al,Ga)$_4$ represents a suitable platform to explore the interplay between lattice-, charge-, and spin degrees of freedom, and associated emergent phenomena. Finally, we address some key questions open to future investigation.

Entropy increases at linear order in scalar-hairy Lovelock gravity

description: In this paper, we investigate the second law of the black holes in Lovelock gravity sourced by a conformally coupled scalar field under the first-order approximation when the perturbation matter fields satisfy the null energy condition. First of all, we show that the Wald entropy of this theory does not obey the linearized second law for the scalar-hairy Lovelock gravity which contains the higher curvature terms even if we replace the gravitational part of Wald entropy with Jacobson-Myers (JM) entropy. This implies that we cannot naively add the scalar field term of the Wald entropy to the JM entropy of the purely Lovelock gravity to get a valid linearized second law. By rescaling the metric, the action of the scalar field can be written as a purely Lovelock action with another metric. Using this property, by analogy with the JM entropy of the purely Lovelock gravity, we introduce a new formula of the entropy in the scalar-hairy Lovelock gravity. Then, we show that this new JM entropy increases along the event horizon for Vaidya-like black hole solutions and therefore it obeys a linearized second law. Moreover, we show that different from the entropy in $F($Riemann$)$ gravity, the difference between the JM entropy and Wald entropy also contains some additional corrections from the scalar field.

description: The aim of the study was to determine the preferences and behavior of students on the milk and dairy products market. The source material for this study were survey conducted in 2012 on a purposely selected sample of 200 students of the University of Life Sciences in Poznań. It has been found that milk and dairy products are a very important component of the diet of students. Nearly half of them consume these products every day. The milk they use mainly for whitening coffee, cocoa preparation and consume them with cereal. Most often buy UHT milk in a carton, with a high fat content. Among dairy products prefer yoghurt and hard cheese. Milk and dairy products consume primarily because of their flavor and health properties. Taste is also the most important factor for buying these products. Milk products they purchase most often in supermarkets and hypermarkets.
