description: Socio-economic conditions compel the milk industry and producers to undertake measures aimed at increasing production profitability. Above all, the specifics of long-ripened cheese production requires augmenting the casein content in milk. This is however obstructed by the lack of an established economically justified threshold value for this ingredient that would guarantee the efficiency of cheese production and correct settlement of accounts with the breeders. The presented study results for the 45th batch of milk refer to ingredients that decide the efficiency of the production of cheese from milk with different casein levels. The raw milk with a higher casein content contained 0.20% more protein (P ≤ 0.014) and 0.08% more k-casein (P ≤ 0.047). In comparison to the milk with a lower casein content, the obtained whey and cheese slurry contained 0.09% less protein (P ≤ 0.035) and 1.92% more dry non-fat matter (P ≤ 0.049). This milk also yielded 0.4% more cheese (P ≤ 0.039). It can be assumed that the selection of milk pools on the basis of their casein contents can improve production efficiency and set new trends in assessments of processing milk usability.

description: The structure of a superconducting vortex has been studied theoretically for a dirty antiferromagnetic superconductor (AFSC), modelling an AFSC as a doped semi-metal with s-wave superconducting pairing and antiferromagnetic (dielectric) interaction between electrons (holes). It is also supposed that the quasiparticles dispersion law possesses the property of nesting. The distribution of the superconducting and magnetic order parameters near the vortex core is calculated. It is shown that the antiferromagnetic order, been suppressed at large distances, is restored around the superconducting flux and the vortex core is in fact insulating and antiferromagnetic, in stark contrast to the normal metal cores of traditional superconductors. Moreover, our model calculations predict that as the temperature decreases the flux region of the superconductivity and antiferromagnetism coexistence increases.

From the second magnetization peak to peak effect. A study of superconducting properties in Nb films and MgB2 bulk samples

description: We report on magnetic and magnetoresistance measurements in two categories of superconducting Nb films grown via magnetron sputtering and MgB2 bulk samples. In the first category, films of Tc = 9.25 K were produced by annealing during deposition. In these films, the magnetic measurements exhibited the so-called second magnetization peak (SMP), which is accompanied by thermomagnetic instabilities (TMI). The characteristic field Hfj, where the first flux jump occurs, has been studied as a function of the sweep rate of the magnetic field. Interestingly, in the regime T < 6.4 K, the respective line Hfj(T) is constant, Hfj(T < 6.4 K) = 40 Oe. A comparison to TMI observed in MgB2 bulk samples is also performed. Our experimental findings cannot be described accurately by current theories on TMI. In the second category, films of Tc = 8.3 K were produced without annealing during deposition. In such films, we observed a peak effect (PE). In high magnetic fields the PE is accompanied by a sharp drop and a narrow hysteretic behaviour in the measured magnetoresistance. In contrast to experimental works presented in the past, the comparison of our magnetic measurements with the magnetoresistance data suggests that the appearance of surface superconductivity rather than the melting transition of vortex matter is the cause of the observed behaviour.

description: The basis of existing of agriculture farms in the condition of free market is their ability for competition. Membership of Poland in EU structures enabled gaining new aid grants for farm producers within CAP. To 2004 polish agriculture was characterized by used and depreciated farm equipment. Next programs as SAPARD, SOP, RADP enabled to fulfill some modernize obligations. In the article the use of modernization support in 2209 farms on Lower Silesia in division for area groups and poviats has been presentend in period 2007-2013. Basically bigger units have used modernization funds. Average values of financial support per 1 ha of UAA in poviats were lower than level of direct payments. The highest share of EU financial support was used by bigger farms, moreover the quota of modernization cash flow was also directed to higher acreage farms. Beneficiaries of modernization support improved management processe in farms, optymalized unit costs of energy and labour and become more competitive. The study confirmed serious variability of UE financial support on the level of districts.

description: We report the discovery, from our preliminary survey of the Praesepe open cluster, of two new spectroscopically confirmed white dwarf candidate members. We derive the effective temperatures and surface gravities of WD0837+218 and WD0837+185 (LB5959) to be 17845 +555 -565K and log g = 8.48 +0.07 -0.08 and 14170 +1380 -1590K and log g =8.46 +0.15 -0.16 respectively. Using theoretical evolutionary tracks we estimate the masses and cooling ages of these white dwarfs to be 0.92+/-0.05Msun and 280 +40 -30Myrs and 0.90+/-0.10Msun and 500 +170 -100Myrs respectively. Adopting reasonable values for the cluster age we infer the progenitors of WD0837+218 and WD0837+185 had masses of 2.6 < M < Mcrit Msun and 2.4 < M < 3.5Msun respectively, where Mcrit is the maximum mass of a white dwarf progenitor. We briefly discuss these findings in the context of the observed deficit of white dwarfs in open clusters and the initial mass-final-mass relationship.

We take robotic systems as an exemplar of complex systems and rigorously describe actuators, sensors, and algorithms using this framework.

Helical motion and the origin of QPO in blazar-type sources
Creators: name: Rieger, Frank M.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent observations and analysis of blazar sources provide strong evidence for (i) the presence of significant periodicities in their lightcurves and (ii) the occurrence of helical trajectories in their radio jets. In scenarios, where the periodicity is caused by differential Doppler boosting effects along a helical jet path, both of these facts may be naturally tied together. Here we discuss four possible driving mechanisms for the occurrence of helical trajectories: orbital motion in a binary system, Newtonian-driven jet precession, internal jet rotation and motion along a global helical magnetic field. We point out that for non-ballistic helical motion the observed period may appear strongly shortened due to classical travel time effects. Finally, the possible relevance of the above mentioned driving mechanisms is discussed for Mkn~501, OJ 287 and AO 0235+16.

description: The assessment of productivity as a measure of efficiency changes over time in a selected food processing industry was the goal of the paper. Estimation of the produtivity was carried out using the Malmquist TFPC index (total factor productivity index), which is based on a deterministic approach. The DEA-based approach allows decomposing of the TFPC indices into: technical change (ΔT), technical efficiency change (ΔTE) and scale efficiency change (ΔSE). A panel data from the companies of a key food processing sector, namely the meat processing, was used. The sample consisted of above 200 objects. The results indicated which of the decomposed indices (ΔT, ΔTE, ΔSE) had the greatest impact on productivity changes in the analyzed sector.
Ensemble from Coarse Graining: Reconstructing the Interior of an Evaporating Black Hole

description: In understanding the quantum physics of a black hole, nonperturbative aspects of gravity play important roles. In particular, huge gauge redundancies of a gravitational theory at the nonperturbative level, which are much larger than the standard diffeomorphism and relate even spaces with different topologies, allow us to take different descriptions of a system. While the physical conclusions are the same in any description, the same physics may manifest itself in vastly different forms in descriptions based on different gauge choices. In this paper, we explore the relation between two such descriptions, which we refer to as the global gauge and unitary gauge constructions. The former is based on the global spacetime of general relativity, in which understanding unitarity requires the inclusion of subtle nonperturbative effects of gravity. The latter is based on a distant view of the black hole, in which unitarity is manifest but the existence of interior spacetime is obscured. These two descriptions are complementary. In this paper, we initiate the study of learning aspects of one construction through the analysis of the other. We find that the existence of near empty interior spacetime manifest in the global gauge construction is related to the maximally chaotic, fast scrambling, and universal dynamics of the horizon in the unitary gauge construction. We use the complementarity of the gauge choices to understand the ensemble nature of the gravitational path integral in global spacetime in terms of coarse graining and thermality in a single unitary theory that does not involve any ensemble nature at the fundamental level. We also discuss how the interior degrees of freedom are related with those in the exterior in the two constructions. This relation emerges most naturally as entanglement wedge reconstruction and the effective theory of the interior in the respective constructions.

We propose a multifractal based algorithm, which quantifies intermittence on the basis of the statistical distribution of the 'strength of burstiness', estimated within a sliding window. Interesting multi-scale phenomena observed by the Cluster spacecraft include large scale motion of the current sheet and bursty bulk flow associated turbulence, interpreted as a cross-scale coupling (CSC) process.

description: The main aim of the article was to present the liquid biofuel sector against the bioeconomy and sustainable development of agriculture in order to show the dilemma of the bioeconomy. It lies in the fact that the production of first generation biofuels (from agricultural raw materials) is a segment of the bioeconomy, but it does not support the idea of sustainable development of agriculture. Bioeconomy mainly includes agriculture and forestry and related industries, therefore, the food industry and wood industry, but also the bioenergy sector. It can be concluded that the production of biofuels belongs to bioeconomy. In turn, sustainable development means the simultaneous integration of the objectives in environmental, economic and social areas. In principle, the production of biofuels from agricultural raw materials (cereals, sugarcane, oilseeds) should support the idea of the sustainable development, but in practice it denies.

description: We consider an array of XX spin-1/2 chains coupled to acoustic phonons and placed in a magnetic field. Treating the phonons in the mean field approximation, we show that this system presents a first order transition as a function of the magnetic field between a partially magnetized distorted state and the fully polarized undistorted state at low temperature. This behavior results from the magnetostriction of the coupled chain system. A dip in the elastic constant of the material near the saturation field along with an anomaly in the magnetic susceptibility is predicted. We also predict the contraction of the material as the magnetic field is reduced (positive magnetostriction) and the reciprocal effect i.e. a decrease of magnetization under applied pressure. At higher temperature, the first order transition is replaced by a crossover. However, the anomalies in the susceptibilities in the system near the saturation field are still present. We discuss the relevance of our analysis in relation to recent experiments on spin-1/2 chain and ladder materials in strong magnetic fields.

description: The paper presents the results of grouping of districts of the province Małopolska with respect to the similarity of agrarian structure. To group fuzzy classification method was used. The calculations were made on the basis of PSR 2010 (Polish Agricultural Census) takes into account the following groups of holdings area : 0-1 ha, 1-2 ha, 2-5 ha, 5-10 ha, 10-15 ha, 15 ha and more. The article shows which area is occupied by these types of farms according to typological groups of counties. As a result of the calculations 4 groups of province were obtained. Each group has a different structure from the others,, but the mainly differences are related to the first four area classes. You may have noticed a direct connection between variation in the structure of farms in the counties of Malopolska with the diversity of natural conditions occurring in this area. Significant influence is the agglomeration of Krakow and Śląsk.
title: Factors affecting the use of computer assisted learning by further education biology teachers
Creators: name: Barnard, Jane
Publisher: name: The Open University
Year: 1999

description: The UK educational system is currently under pressure from many quarters to increase its use of educational technology. Within this context, this thesis investigates the nature of a range of factors which influence teachers' use of computer assisted learning (CAL), focusing on biology teachers in Further Education (FE). The factors were identified from the literature, and include aspects such as resourcing, and the teachers' classroom practice and educational philosophies. There were three main stages to the thesis research. The first stage involved a survey of 68 FE biology teachers. The second stage involved two interviews each with 20 of the survey respondents, producing approximately 80 hours of audiotape. The third stage involved a total of nine classroom observations with six of the interviewees, producing approximately nine hours of videotape and nine hours of audiotape. The conclusions describe how the factors interacted to affect CAL use amongst the FE biology teachers. The findings stress the importance of teachers' development of classroom familiarity with computers; this development was encouraged by both current and previous exposure to the classroom practice of other computer-using teachers. The teachers involved in the study were generally positive about educational technology, but critical about many currently available biology programs; this critical perspective was particularly evident amongst the more student-centred teachers. The findings outline a list of criteria that the teachers appeared to consider when reviewing programs, and describe the relationship between the use of software and the teachers' classroom practice. The conclusions outline the potential of a framework developed by Brown and McIntyre (1993) for future studies of how classroom practice affects, and is affected by, educational technology. The conclusions also make recommendations, based on the findings, to those responsible for FE policy and staff development about how they might help to increase teachers' use of CAL.

description: In this work, we investigate the interactions between the charmed-strange meson ($D_s, D_s^{*}$) in $H$-doublet and the (anti-)charmed-strange meson ($D_{s1}, D_{s2}^{*}$) in $T$-doublet, where the one boson exchange model is adopted by considering the $S$-$D$ wave mixing and the coupled-channel effects. By extracting the effective potentials for the discussed $H_s\bar{T}_s$ and $H_s{T}_s$ systems, we try to find the bound state solutions for the corresponding systems. We predict the possible hidden-charm hadronic molecular states with hidden strangeness, i.e., the $D_s^{*}\bar D_{s1}+c.c.$ states with $J^{PC}$=$0^{--}, 0^{-+}$ and the $D_s^{*}\bar D_{s2}^{*}+c.c.$ states with $J^{PC}$=$1^{--}, 1^{-+}$. Applying the same theoretical framework, we also discuss the $H_s T_s$ systems. Unfortunately, the existence of the open-charm and open-strange molecular states corresponding to the $H_s T_s$ systems can be excluded.

description: Super-sonic downflows have been observed in transition region spectra above numerous sunspots; however, little research has been conducted to date into how persistent these signatures are within sunspots on time-scales longer than a few hours. Here, we analyse the lead sunspot of AR 12526 to infer the properties and evolution of super-sonic downflows occurring within it. Sixteen large, dense raster scans sampled by IRIS are analysed. These rasters tracked the lead sunspot of AR 12526 at discrete times between the 27th March 2016 and the 2nd April 2016. One sit-and-stare observation acquired on the 1st April 2016 is also studied in order to analyse the evolution of super-sonic downflows on shorter time-scales. Super-sonic downflows are variable within this sunspot both in terms of spatial structuring and velocities. 13 of the 16 raster scans display some evidence of super-sonic downflows in the Si IV 1394 Å line co-spatial to a sustained bright structure detected in the 1400 Å slit-jaw imaging channel, with a peak velocity of 112 km s^{-1} being recorded on the 29th March 2016. Evidence for super-sonic downflows in the O IV 1401 Å line was found in 14 of these rasters, with the spatial structuring differing from that inferred from the Si IV 1394 Å line. In the sit-and-stare data, no dual flow is initially detected, however, a super-sonic downflow does develop after 60 minutes. This downflow accelerates from 73 km s^{-1} to close to 80 km s^{-1} in both the Si IV 1394 Å and O IV 1401 Å lines over the course of 20 minutes before the end of the observation. The morphology of these downflows evolved over the course of both hours and days and was often different in the Si IV 1394 Å and O IV 1401 Å lines. These events were found co-spatial to a bright region in the core of the Si IV 1394 Å line which appeared to form at the foot-points of coronal fan loops.

description: Crop rotations are known to have two main kinds of economic effects: direct effects on potential yields and on the productivity of different inputs, and indirect effects on economically optimal input levels, especially pesticides and fertilizers. The main objective of this article is to uncover the mechanisms through which crop rotation effects affect the acreage choices of forward-looking farmers, in a dynamic programming framework. Whereas most models considering acreage choices with crop rotation effects are based on discrete choice models at the plot level, our model considers a farm level strategy. This implies that our theoretical modeling framework is closely related to the models commonly used for empirically investigating farmers’ acreage choices, either in the multicrop econometric literature or in the mathematical programming literature. We provide original results aimed at characterizing the properties of optimal acreage choices accounting for crop rotation effects and constraints in an uncertain context. Using a stochastic programming approach together with a Lagrangian approach we show that optimal dynamic acreage choices can be formally characterized as static acreage choices with contingent renting/lending markets for acreages with specific preceding crops. The crop rotation constraint Lagrange multipliers provide the renting/lending prices of acreages with specific crop histories. The results presented in the article are mainly theoretical. Our modeling framework can easily be implemented in practice since it mainly considers quadratic programming problems and their solution functions.

description: The aim of the work was an analysis and an evaluation of Resource and Process Consumption Accounting which have been initiated from 2010 in dairy co-operative Spomlek. Introduced account of charges is characterized by transparency and concentration on the most important elements i.e. resources, actions and cost objects (products and customers). The particularly important factor which contributed to success of initiating of the new system was the possibility of reference of cost data to physical sizes administered by managers. The cost-awareness was increased among employees by the cross sectional analysis of action costs and resources - from the moment of gaining raw material until the sales of ready products. It means a mapping of flow path of product and an appraisement of value added on different stages of life of the product. Carried out analysis of resource and process consumption accounting in SM Spomlek confirms that it is an essential tool to servants of development.

description: The method developed by Stock and Stock (1999) to derive absolute magnitudes and intrinsic colors is applied to simulated low-resolution spectra. The simulation is made by convolving real spectra with a Gaussian function, $σ$ (the full width at half maximum) related to the final spectral resolution. The accuracy with which the stellar parameters are determined indicates that the method may be applied to typical objective-prism spectra. We show that changes in the spectral resolution do not significantly affect the stellar parameters obtained with this method for early-type stars, whereas for later-type stars an improved approach is necessary.

description: We present a novel approach for designing complex approximate arithmetic circuits that trade correctness for power consumption and play important role in many energy-aware applications. Our approach integrates in a unique way formal methods providing formal guarantees on the approximation error into an evolutionary circuit optimisation algorithm. The key idea is to employ a novel adaptive search strategy that drives the evolution towards promptly verifiable approximate circuits. As demonstrated in an extensive experimental evaluation including several structurally different arithmetic circuits and target precisions, the search strategy provides superior scalability and versatility with respect to various approximation scenarios. Our approach significantly improves capabilities of the existing methods and paves a way towards an automated design process of provably-correct circuit approximations.

description: The $\mathbf{O}(D,D)$ covariant generalized metric, postulated as a truly fundamental variable, can describe novel geometries where the notion of Riemannian metric ceases to exist. Here we quantize a closed string upon such backgrounds and identify flat, anomaly-free, non-Riemannian string vacua in the familiar critical dimension, $D{=26}$ (or $D{=10}$). Remarkably, the whole BRST closed string spectrum is restricted to just one level with no tachyon, and matches the linearized equations of motion of Double Field Theory. Taken as an internal space, our non-Riemannian vacua may open up novel avenues alternative to traditional string compactification.

description: REBCO coated conductor is a high temperature superconductor that has a wide range of applications, one of which is the current leads of magnet systems. In the design of current leads, it is crucial to minimize their thermal conduction while maintain stable electrical conduction. Therefore, thermal conductivity of various REBCO tapes need to be characterized and analyzed. In this research, we measured thermal conductivity of REBCO tapes in the longitudinal direction from 4.2 to 200 K. Samples with Cu, Ag and Ag-3at%Au stabilizers of various thicknesses were measured. The electrical conductivity of these stabilizers was also characterized by residual resistance ratio (RRR) measurements and correlated with the thermal conductivity results. We showed that in samples with 10 micron or less Cu stabilizer, thermal conduction is dominated by that of the Cu which has much higher thermal conductivity than the Hastelloy substrate and the superconductor layer. In addition, the sample with 3 micron Ag-3at%Au stabilizer has significantly lower thermal conductivity than that with 3 micron silver stabilizer. It is concluded that REBCO with Ag-3at%Au stabilizer is promising for current lead applications.

description: Absence of level repulsion between extended states in random non-Hermitian systems is demonstrated. As a result, the general Wigner-Dyson distributions of level spacing of diffusive metals in the usual Hermitian systems is replaced by the Poisson distribution for quasiparticle level spacing of non-Hermitian disordered metals in the thermodynamic limit of infinite system size. This is a very surprising result because Poisson statistics is universally true for the Anderson insulators where energy eigenstates do not overlap with each other so that energy levels are independent from each other.For disordered metals where different eigenstates overlap with each other, one should expect different levels trying to stay away from each other so that the Poisson distribution should not apply there. Our results show that the larger non-Hermitian energy (dissipation) can invalidate level repulsion principle that holds dearly in quantum mechanics. Thus, our theory provides a unified picture for recent discovery of so called "level attraction" in various systems. It provides also a theoretical basis for manipulating energy levels.

title: The Potential Of Fuel Cells To Reduce Energy Demands And Pollution From The UK Transport Sector

description: Atmospheric carbon dioxide and pollution due to the burning of fossil fuels is increasing. Many scientists attribute global warming to the rising levels of carbon dioxide and other pollutants, some of which also pose risks to health. These can be reduced by the more efficient use of conventional fuels and the development of non-polluting energy resources. Fuel cells offer a highly efficient and low polluting method of generating electricity, and are under development for both the power generation and transport sectors. There is a need to assess (a) emissions from fuel cells using various fuels and (b) ways of introducing such technology to transportation in the near future. Fuel consumption, energy and emissions from the production and use of fuels (hydrogen, methane, propane, petrol, diesel, alcohols and rape methyl ester) are calculated per kilowatt hour of fuel cell output over a range of efficiency. These are compared with those for internal combustion engines with advanced exhaust control and for the recharging of battery driven vehicles. The results, which are applicable to both transport and power generation, enable the best low pollution fuels to be selected and are used to calculate through life emissions for public transport buses. Fuel cells are an ideal solution to reduce pollution from transport, but their commercial development in this field is further away than that for stationary applications. Thus, a transition stage is recommended where fuel cell electrical power stations, based on existing demonstrators, are used to recharge fleets of battery driven vehicles during the development of mobile fuel cell systems. These fleets include public transport and commercial vehicles. Also, fuel cell power stations could provide energy for electric trains. A combined system is proposed where electric trains recharge battery driven commercial vehicles during long journeys. The above proposals would enhance fuel cell development, introducing them alongside current transport systems, possibly using the same fuel.

Enhancing Deeper Learning Using Empathy and Creativity In Role-Playing Serious Games
Creators: name: Marda, Maria
Publisher: name: University of Westminster

description: Although educational technology has been widely used in education and remarkably supported instruction and assessment in face-to-face instruction, remote teaching and e-learning, teaching approaches have little deviated from the conventional approaches. Since the last decade, there is a shift in education to redesign teaching strategies. Education set priorities in promoting and supporting deeper learning to empower learners in thinking critically and creatively and gain skills and expertise in transferring their knowledge and applying it in other contexts to solve new problems. Concurrently, there is a remarkable interest by educators in harnessing the power of digital games and transferring it in education by designing Serious games. Serious Games are digital games designed to support learning, training, skill acquisition, and social and behavioural change. Serious Games integrate game design elements and gamification elements such as story, characters, score, visual objects, and rewards to create a positive mood while learning, increasing excitement, interest, motivation and engagement. Bridging the necessity for guiding learners in reaching deeper learning with Serious Games, this research thesis proposes the DeLEC pedagogical framework. DeLEC provides a pedagogic model which includes an iterative learning process of instruction, assessment and feedback integrating the elements of empathy and creativity. Aiming to investigate whether the proposed DeLEC framework is valid and indeed supports learners in reaching deeper learning, a Serious Game is designed to apply the phases of the DeLEC framework. The Serious Game is called Stronger and has the form of role-playing designed with a story and characters on a fictitious scenario around domestic violence and abuse (DVA). Stronger was tested with participants in a comparative study with an e-learning course on the same learning material. The results emerged from the data analysis demonstrated higher results in learning and deeper learning compared to the e-learning course leading to conclusions that confirm that the proposed DeLEC framework indeed assists learners in reaching Deeper Learning with Serious Games.

description: If R-parity conserving supersymmetry exists below the TeV-scale, new particles will be produced and decay in cascades at the LHC. The lightest supersymmetric particle will escape the detectors, thereby complicating the full reconstruction of the decay chains. In this paper we expand on existing methods for determining the masses of the particles in the cascade from endpoints of kinematical distributions. We perform scans in the mSUGRA parameter space to delimit the region where this method is applicable. From the examination of theoretical distributions for a wide selection of mass scenarios it is found that caution must be exerted when equating the theoretical endpoints with the experimentally obtainable ones. We provide analytic formulae for the masses in terms of the endpoints most readily available. Complications due to the composite nature of the endpoint expressions are discussed in relation to the detailed analysis of two points on the SPS~1a line. Finally we demonstrate how a Linear Collider measurement can improve dramatically on the precision of the masses obtained.
