description: The $XYZ$ antiferromagnetic spin-$1/2$ chain with alternation of the exchange and anisotropy couplings in the presence of uniform and staggered axial magnetic fields is studied. The analysis is done using the effective quadratic fermionic Hamiltonian resulting from the Hartee-Fock approximation. Combining the exact and the mean-field methods, the local and string order parameters on the ground-state phase diagram of the model are identified and calculated. We found a topological phase with oscillating string order with a period of four lattice spacings, not reported before for this model. A detailed analysis of patterns of the string order is given. The special $XXZ$ limit of the model with additional $U(1)$ symmetry brings about, in agreement with the Lieb-Schultz-Mattis theorem and its extensions, plateaux of magnetization and some additional conserving quantities. We have shown that in the $XYZ$ chain, where the plateaux are smeared, the robust oscillating string order parameter is continuously connected to its $XXZ$ limit. Also, the non-trivial winding number and zero-energy localized Majorana edge states, as additional attributes of topological order, are robust in that phase, even off the line of $U(1)$ symmetry.

description: The aim of the work is to present the economic situation of the Agricultural Social Insurance Fund (KRUS) and to evaluate its activities from the perspective of the farmers insured in it from the area of the County of Przasnysz. For that purpose the data gathered by the KRUS and the results of the survey conducted in 2012 covering 82 insured farmers were used. Disappointment with the currently functioning system of agricultural social insurance was declared by as many as 53.7% of the respondents. This is not equivalent to willingness to liquidate that institution. To the contrary, 73.2% of the respondents see the need for existence of a separate insurance system highlighting at the same time the necessity for upgrading it (45.1%). The changes should not involve intervention of the State in the fi nancial aspects of the KRUS but the mechanisms of computing the contributions or early retirement pensions for farmers. On numerous occasions the respondents presented arguments concerning inadequacy of the level of contributions paid to the level of benefi ts received.

description: Motived by the heat flow and bubble analysis of biharmonic mappings, we study further regularity issues of the fourth order Lamm-Riviere system $$Δ^{2}u=Δ(V\cdot\nabla u)+{\rm div}(w\nabla u)+(\nablaω+F)\cdot\nabla u+f$$ in dimension four, with an inhomogeneous term $f$ which belongs to some natural function space. We obtain optimal higher order regularity and sharp Holder continuity of weak solutions. Among several applications, we derive weak compactness for sequences of weak solutions with uniformly bounded energy, which generalizes the weak convergence theory of approximate biharmonic mappings.

The effects of Wimba on learning : a students and faculty perspective
Creators: name: Wang, Tianxuan
Publisher: name: University of British Columbia
Year: 2010

description: One of the ultimate goals of language education is to enhance students’ communicative competence (Ommagio Hadley, 2001). Recent research indicates that Wimba, as an online voice tool, is beneficial to develop students’ conversational skills (Cho & Carey, 2001; Kabata, Wiebe & Chao, 2004; McIntosh, Braul, & Chao, 2003; Poza, 2005). Those studies focused mainly on the advantage of Wimba for developing learner’s conversational skills but did not explore how to use the software most effectively for teaching and learning. Therefore, this current study aims to investigate: 1) what was students and instructor’s perspective on Wimba as a learning tool and what was the reason behind that; 2) how did the Wimba-based activities designed by the instructor meet the objectives of the course; 3) whether there is a certain type of learning that can be facilitated most by Wimba; 4) what are the in-depth pedagogical suggestions for improving intelligent Wimba usage for future students and instructors. A class of Cantonese speakers learning Mandarin as a second dialect and its instructor were chosen for this study. Both quantitative and qualitative data were collected through questionnaires and interviews. Findings indicate that both students and instructor evaluated their experience with Wimba positively. However, the effectiveness of the implementation of this software did not meet its full potential in this case because the designed activities were limited by the instructor’s time limitations. Students and instructor felt that Wimba was most effective for practice listening and speaking for novice and intermediate learners. Future application of the software should focus on providing students opportunities to be involved in tasks that require various language skills to maximize diversity of registers of use. At the same time, technology-related workshops for the instructors should not only focus on the simple "how-to" of the software. Instead, they should provide instructors detailed information and recommendation on how to use the technology most creatively and effectively for teaching and learning.

description: Magnetic and electrical properties of four series of rare earth cobaltates of the formula La0.7-xLnxCa0.3CoO3 with Ln = Pr, Nd, Gd and Dy have been investigated. Compositions close to x = 0.0 contain large ferromagnetic clusters or domains, and show Brillouin-like behaviour of the field-cooled DC magnetization data with fairly high ferromagnetic Tc values, besides low electrical resistivities with near-zero temperature coefficients. The zero-field-cooled data generally show a non-monotonic behaviour with a peak at a temperatures slightly lower than Tc. The near x = 0.0 compositions show a prominent peak corresponding to the Tc in the AC-susceptibility data. The ferromagnetic Tc varies linearly with x or the average radius of the A-site cations, (rA). With increase in x or decrease in (rA), the magnetization value at any given temperature decreases markedly and the AC-susceptibility measurements show a prominent transition arising from small magnetic clusters with some characteristics of a spin-glass. Electrical resistivity increases with increase in x, showed a significant increase around a critical value of x or (rA), at which composition the small clusters also begin to dominate. These properties can be understood in terms of a phase separation scenario wherein large magnetic clusters give way to smaller ones with increase in x, with both types of clusters being present in certain compositions. The changes in magnetic and electrical properties occur parallely since the large ferromagnetic clusters are hole-rich and the small clusters are hole-poor. Variable-range hopping seems to occur at low temperatures in these cobaltates.

description: One of the important problems of Polish agriculture is insuffi cient state horizontal integration of agricultural producers. Identifi cation of factors that affect the improvement of the competitiveness of producer groups in the food chain can help in the development of such entities. The aim of the publication is to present activities that should improve competitiveness in the food chain which are undertaken by groups of raw materials producers on the example of fruit and vegetable producers groups operating in Kujawsko-Pomorskie region. In studies the method of participant observation interview were used. The measurement was conducted in late April and May 2013 and included 19 leaders of producer groups. According to them the most important factor infl uencing the market position of the groups in the food chain, was the high quality of the manufactured goods in farms affi liated farmers. Few respondents identifi ed marketing as an opportunity to strengthen the competitive advantage of producer groups in the food supply chain. This is due to the fact that farmers are far removed in the supply chain from consumers with whom they have contact only in the form of market random retail.

description: The potential area of energy crops in Poland is estimated at 1.0–4.5 million ha. The decrease in the prices of energy reduces the high pressure to cut the costs of biomass production. The aim of this study is an analysis of the use of tractors on model farms producing energy crops, which have different areas, intensity of production and quality of soils from different regions of Poland. The use of tractors increased along with the farm area, the soil quality and production intensity. The use of tractors on the smallest farms is low, so they should buy old tractors. A large share of crops for biogas leads to the situation where it takes 20–30 years of work for tractors to achieve full wear of 12,000 hours on farms with 130 ha of farmland, whereas it takes only 8–14 years on farms with 600 and 1500 ha of farmland. Regional differences in the use of tractors increased along with the farm area from 4.7–5.7% on the smallest farms to 10.1–14.8% on the largest farms

subject: prediction of usage
subject: Polish agriculture

description: Mineral fertilizers are considered to be a driving force for production in the present day agriculture. In Poland, from among 2.5 mln tons of compound mineral fertilizers, expressed in a pure ingredient, above 2 mln tons is used in domestic agriculture. Since 1992 has been a growing tendency in the usage of such fertilizers. The main aim of this analysis is to present multifarious forecasts concerning the use of mineral fertilizers in Poland in 2014–2025. Three ways of building a future prediction have been used in the conducted research: extrapolation, adaptation and causal prediction. The analyses pinpoint that till 2025 the estimated growth in the use of mineral fertilizers is going to fl uctuate around 9–23.5% in comparison with the average score in 2010–2013. It is important to mention that in the most probable and sustainable scenario of a transformation in agriculture, this growth is going to amount to about 15%.

description: The PMNS neutrino mixing matrix is given, in general, by the product of two unitary matrices associated with the diagonalization of the charged lepton and neutrino mass matrices, respectively. Assuming that the active flavor neutrinos possess a Majorana mass matrix which is diagonalized by a bimaximal mixing matrix, we give the allowed forms of the charged lepton mixing matrix and the corresponding implied forms of the charged lepton mass matrix. We further assume that the origin of bimaximal mixing is a weakly broken flavor symmetry of the neutrino Majorana mass matrix, corresponding to the conservation of the non-standard lepton charge L' = L_e - L_mu - L_tau. The latter does not predict, in general, the atmospheric neutrino mixing to be maximal. We study the impact of this fact on the allowed forms of the charged lepton mixing matrix and on the neutrino mixing observables, analyzing the case of CP nonconservation in detail. We find, in particular, that the allowed ranges of U_{e3} and of the atmospheric neutrino mixing angle are typically larger when one assumes L' conservation than in the case of exact initial bimaximal mixing. The atmospheric neutrino mixing can take any value inside its currently allowed range, while |U_{e3}|^2 can be as small as 0.007. We discuss under which conditions the atmospheric neutrino mixing angle can be larger or smaller than pi/4. We present also a simple see-saw realization of the implied light neutrino Majorana mass matrix and consider leptogenesis in this scenario.

Non-Markovian dynamics of a two-level system in a bosonic bath and a Gaussian fluctuating environment with finite correlation time

description: The character of evolution of an open quantum system is often encoded in the correlation function of the environment or, equivalently, in the spectral density function of the interaction. When the environment is heterogeneous, e.g. consists of several independent subenvironments with different spectral functions, one of the subenvironments can be considered auxiliary and used to control decoherence of the open quantum system in the remaining part of the environment. The control can be realized, for example, by adjusting the character of interaction with the subenvironment via suitable parameters of its spectral density. We investigate non-Markovian evolution of a two-level system (qubit) under influence of three independent decoherence channels, two of them have classical nature and originate from interaction with a stochastic field, and the third is a quantum channel formed by interaction with a bosonic bath. By modifying spectral densities of the channels, we study their impact on steady states of the two-level system, evolution of its density matrix and the equilibrium emission spectrums. Additionally, we investigate the impact of the rotation-wave approximation applied to the bath channel on accuracy of the results.

description: This paper develops a Tikhonov regularization theory for nonlinear ill-posed operator equations in Banach spaces. As the main challenge, we consider the so-called oversmoothing state in the sense that the Tikhonov penalization is not able to capture the true solution regularity and leads to the infinite penalty value in the solution. We establish a vast extension of the Hilbertian convergence theory through the use of invertible sectorial operators from the holomorphic functional calculus and the prominent theory of interpolation scales in Banach spaces. Applications of the proposed theory involving $\ell^1$, Bessel potential spaces, and Besov spaces are discussed.

The survey subjects were all communes: urban, urban-rural and rural in the Wielkopolskie voivodeship. In conclusion, in 2004–2012 there were major changes in spending funds by communes in Wielkopolska region. It should be noted that in rural communes more funds, than on much-needed expansion of water supply and sewerage systems, are spent on transport, agriculture, and education and upbringing. Given the capital-intensive nature of this type of investment, much of it will not be realised if EU funds are not obtained.

He was posted overseas, arriving in France on 9th July 1915. He was captured by the enemy, tattooed as a prisoner of war on his wrist and set to work in a salt mine.

Prior to the war and following his release and army discharge, Clement was employed as a farm worker, moving around from farm to farm as work became available. In later life he gave up farm work and worked alongside his son-in-law in a factory in Worcester which produced windshields.

description: The aim of the article is to show the impact of market location and the distance from the supply network participants on the occurrence of innovative cooperation between the food industry companies and industry- and science-oriented entities. The methodological part of the article is based on probit modelling. The material necessary for the analyses present in this article has been collected by means of a questionnaire sent to the companies all over Poland. The conducted research confi rmed that the situation when the market or other participants of the supply network (suppliers, customers and competitors) are localised in close proximity to the food industry company has a negative impact on the occurrence of innovative activity between the company and other food industry companies or science-oriented units. On the other hand, the location outside one’s own region stimulates this kind of collaboration.

description: A környezeti fenntarthatósági problémák és azon belül a klímaváltozás negatív hatásait egyre jobban, számszerűbben ismerhetjük. E fenyegetettség a természeti környezet és a bankrendszer kapcsolatának újragondolását is igényli. Amellett, hogy szükségesnek mutatkozik, hogy a hitelintézetek, mint finanszírozók a környezeti fenntarthatóság megvalósításában is markánsabb szerepet játsszanak, nagyobb figyelem irányul arra is, hogy a környezeti anomáliák a bankokra nézve többféle csatornán növekvő pénzügyi kockázatot is jelentenek. Bár Magyarország nem tartozik a klímaváltozás által legdrasztikusabban érintett országok közé, a környezeti problémák valamint a környezeti fenntarthatóság megteremtése hazánkban is igen jelentős kihívást jelent. A tanulmány bemutatja, hogy a megoldások konkretizálásához azonban első lépésként a vállalatok környezetterheléssel, különösen üvegházhatású gázkibocsátással kapcsolatos adatainak közzétételi, jelentési rendszerének kiépítésére lenne szükség. ---------------------------- The negative impacts of environmental sustainability problems and in particular climate change are increasingly understood. This kind of risk requires us to rethink the relationship between the natural environment and the banking system. On the one hand, it seems necessary that banks as financers play a larger role in ensuring environmental sustainability, and on the other hand, there is an increased attention on the financial risks that are driven by environmental anomalies via a number of channels. Even though Hungary is not among the countries most affected by climate change, environmental problems and sustainability in general do pose a serious challange in the country. In order to find the solutions a first step would be to establish a reporting and disclosure framework for firms' environmental footprint and especially for their CO2 emissions.
DC Spin Current Generation in a Rashba-type Quantum Channel

description: We propose and demonstrate theoretically that resonant inelastic scattering (RIS) can play an important role in dc spin current generation. The RIS makes it possible to generate dc spin current via a simple gate configuration: a single finger-gate that locates atop and orients transversely to a quantum channel in the presence of Rashba spin-orbit interaction. The ac biased finger-gate gives rise to a time-variation in the Rashba coupling parameter, which causes spin-resolved RIS, and subsequently contributes to the dc spin current. The spin current depends on both the static and the dynamic parts in the Rashba coupling parameter, $α_0$ and $α_1$, respectively, and is proportional to $α_0 α_1^2$. The proposed gate configuration has the added advantage that no dc charge current is generated. Our study also shows that the spin current generation can be enhanced significantly in a double finger-gate configuration.

Puffing induced in two model systems by microwave assisted drying under vacuum : an experimental and numerical analysis
Creators: name: Ressing, Mareike Johanne
Publisher: name: University of British Columbia
Year: 2010

description: Microwave heating under vacuum (VM) removes water at reduced temperatures while minimally altering desirable biochemical characteristics of foods compared to traditional air drying methods. Concurrently, it achieves much greater drying rates than other vacuum drying methods. Puffing has been observed in VM dried products and reportedly contributes to improved rehydration and eating quality of VM processed foods. However, the underlying mechanisms [of] this phenomenon are poorly understood. Wheat dough and gelatinized potato starch were selected as model systems to investigate VM puffing since their respective rheologies have previously been characterized. The thesis objective was to advance our understanding of the mechanism behind VM puffing, especially with regard to the rheological and dielectric properties of the selected model systems, and use these data, namely wheat dough results, to develop and validate a numerical model of VM puffing. One model system consisted of dough balls prepared with different quality flour, water and salt (0.0-1.5%) and dehydrated at 700 and 1300 W microwave power at 28 Torr absolute pressure. Cylinders of gelatinized potato starch (30-50% starch d.b., 0-2% NaCl, respectively) which served as the second model, were dehydrated at 350, 700, and 1300 W. For both model systems, volume, dielectric properties, Young’s modulus and/or fracture strength were determined. A video recorder was used to observe the dough and starch model systems during dehydration. Both model systems exhibited pronounced puffing which was influenced by applied power levels, salt content, flour type or starch concentration and dielectric properties. While dough already expanded upon dropping chamber pressure, starch gels needed prior heating to decrease resistance to expansion. Both systems exhibited salt dependence with respect to their rheology. Dough showed reduced volume increases as salt concentration and elasticity decreased, while salt containing starch gels exhibited increased brittleness and lack of cohesion that decreased the expansion potential. Finite Element (FE) modeling described the dough development during microwave drying under vacuum. It illustrated that the puffing is highly influenced by the rheological properties of the dough more so than microwave interaction. While the accuracy was lower than expected, it revealed a stronger pressure interaction with the rheological properties in addition to steam-induced puffing. Image analysis used to characterize porosity of the dried product was only moderately successful and pointed to the possibilities in the field rather than offering a solution to current questions.
Compressibility effects in a turbulent transport of temperature field

description: Compressibility effects in a turbulent transport of temperature field are investigated applying the quasi-linear approach for small Péclet numbers and the spectral $τ$ approach for large Péclet numbers. Compressibility of a fluid flow reduces the turbulent diffusivity of the mean temperature field similarly to that for particle number density and magnetic field. However, expressions for the turbulent diffusion coefficient for the mean temperature field in a compressible turbulence are different from those for the mean particle number density and the mean magnetic field. Combined effect of compressibility and inhomogeneity of turbulence causes an increase of the mean temperature in the regions with more intense velocity fluctuations due to a turbulent pumping. Formally, this effect is similar to a phenomenon of compressible turbophoresis found previously [J. Plasma Phys. {\bf 84}, 735840502 (2018)] for non-inertial particles or gaseous admixtures. Gradient of the mean fluid pressure results in an additional turbulent pumping of the mean temperature field. The latter effect is similar to turbulent barodiffusion of particles and gaseous admixtures. Compressibility of a fluid flow also causes a turbulent cooling of the surrounding fluid due to an additional sink term in the equation for the mean temperature field. There is no analog of this effect for particles.

description: Higher-order topology realizes topologically robust corner modes as a manifestation of nontriviality. We theoretically propose non-Hermitian skin effects which stem from second-order topology of chiral-symmetric Hermitian systems. It is found that the skin modes are localized at the corners. We demonstrate two types of second-order topological skin effects by two-dimensional intrinsic and extrinsic second-order topology. The intrinsic second-order topological skin effect is characterized topologically by bulk inversion symmetry as well as chiral symmetry. Meanwhile, the extrinsic second-order topological skin effect occurs from the topological correspondence between the edges and corners. We show that the non-Hermitian skin modes emerge by using a relationship between second-order and conventional first-order topology.
