description: The article is described the theoretical basis of internal control and its practical aspects in the work of meat processing enterprises (a case in the meat processing industry in Ukraine). The purpose of the research is to establish the theoretical foundations of the internal control and its improvement in the activity of meat processing plants of various forms of management. It is proposed to use precisely internal control among other names of domestic control. Definition of internal control, its subject and purpose are improved. The subjects and objects of internal control are determined; the principles of its implementation are supplemented. Specific control tasks in meat processing plants according to the needs of this industry are outlined. Specific examples of control subjects are presented and the role of the revision commission is emphasized. The state of internal control in meat processing plants in Ukraine is investigated and it is established that it has a bad condition and unfounded approach to its implementation by managers of meat processing enterprises. To improve the situation we recommend that each meat processing enterprise have in its staff a revision commission or an apposer (auditor). It is established that internal control is more effective in joint-stock companies than in limited liability companies. The necessity of internal control as an important element in the enterprise management system is accented.

description: We say that a collection Gamma of geodesics in the hyperbolic plane H^2 is a modular pattern if Gamma is invariant under the modular group PSL_2(Z), if there are only finitely many PSL_2(Z)-equivalence classes of geodesics in Gamma, and if each geodesic in Gamma is stabilized by an infinite order subgroup of PSL_2(Z). For instance, any finite union of closed geodesics on the modular orbifold H^2/PSL_2(Z) lifts to a modular pattern. Let S^1 be the ideal boundary of H^2. Given two points p,q in S^1 we write pq if p and q are the endpoints of a geodesic in Gamma. (In particular pp.) We show that is an equivalence relation. We let Q_Gamma=S^1/ be the quotient space. We call Q_Gamma a modular circle quotient. In this paper we will give a sense of what modular circle quotients `look like' by realizing them as limit sets of piecewise-linear group actions

description: We review recent studies demonstrating a nonuniversal (continuously variable) survival exponent for history-dependent random walks, and analyze a new example, the hard movable partial reflector. These processes serve as a simplified models of infection in a medium with a history-dependent susceptibility, and for spreading in systems with an infinite number of absorbing configurations. The memory may take the form of a history-dependent step length, or be the result of a partial reflector whose position marks the maximum distance the walker has ventured from the origin. In each case, a process with memory is rendered Markovian by a suitable expansion of the state space. Asymptotic analysis of the probability generating function shows that, for large t, the survival probability decays as S(t) \sim t^{-delta}, where δvaries with the parameters of the model. We report new results for a hard partial reflector, i.e., one that moves forward only when the walker does. When the walker tries to jump to the site R occupied by the reflector, it is reflected back with probability r, and stays at R with probability 1-r; only in the latter case does the reflector move (R \to R+1). For this model, delta = 1/2(1-r), and becomes arbitrarily large as r approaches 1. This prediction is confirmed via iteration of the transfer matrix, which also reveals slowly-decaying corrections to scaling.

description: Observations of the Earthshine off the Moon allow for the unique opportunity to measure the large-scale Earth atmosphere. Another opportunity is realized during a total lunar eclipse which, if seen from the Moon, is like a transit of the Earth in front of the Sun. We thus aim at transmission spectroscopy of an Earth transit by tracing the solar spectrum during the total lunar eclipse of January 21, 2019. Time series spectra of the Tycho crater were taken with the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in its polarimetric mode in Stokes IQUV at a spectral resolution of 130000 (0.06 Å). In particular, the spectra cover the red parts of the optical spectrum between 7419-9067 Å. The spectrograph's exposure meter was used to obtain a light curve of the lunar eclipse. The brightness of the Moon dimmed by 10.75 mag during umbral eclipse. We found both branches of the O$_2$ A-band almost completely saturated as well as a strong increase of H$_2$O absorption during totality. The deep penumbral spectra show significant excess absorption from the NaI 5890 Ådoublet, the CaII infrared triplet around 8600 Å, and the KI line at 7699 Åin addition to several hyper-fine-structure lines of MnI and even from BaII. The detections of the latter two elements are likely due to an untypical solar center-to-limb effect rather than Earth's atmosphere. The absorption in CaII and KI remained visible throughout umbral eclipse. A small continuum polarization of the O$_2$ A-band of 0.12\% during umbral eclipse was detected at 6.3$σ$. No line polarization of the O$_2$ A-band, or any other spectral-line feature, is detected outside nor inside eclipse. It places an upper limit of $\approx$0.2\% on the degree of line polarization during transmission through Earth's atmosphere and magnetosphere.

description: In this paper we give the topological classification of real primary Kodaira surfaces and we describe in detail the structure of the corresponding moduli space. One of the main tools is the orbifold fundamental group of a real variety. Our first result is that if $(S, σ)$ is a real primary Kodaira surface, then the differentiable type of the pair $(S,σ)$ is completely determined by the orbifold fundamental group exact sequence. This result allows us to determine all the possible topological types of $(S, σ)$. Finally, we show that once we fix the topological type of $(S, σ)$ corresponding to a real primary Kodaira surface, the corresponding moduli space is irreducible (and connected).

title: The effects of fatty acids and antioxidants on U937 monocytes used as a model for the lipid disturbance in schizophrenia
Creators: name: Obajimi, Oluwakemi
Publisher: name: The Open University
Year: 2003

description: Schizophrenia is a devastating mental disease affecting approximately 1% of all populations. Recent studies have suggested that deficient uptake of free fatty acids or excessive breakdown of cell-membrane phospholipids, directly or indirectly triggered by lipid peroxidative damage, may be associated with schizophrenia and possibly other neurodegenerative disorders.

 This study provides more information on the influence of the presence of different fatty acids (FAs): stearic acid (SA), oleic acid (OA), arachidonic acid (AA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) and dietary antioxidants (ascorbic acid, atocopherol, f3-carotene and astaxanthin) as components of the culture-medium on the human monocytic cell line (U937) by the measurements of cell-viability, productions of by-products of lipid peroxidation (lipid hydroperoxides and volatile hydrocarbons), AA release/uptake and cPLA2 expression upon induced-oxidative stress with the radical mediating system oft-butyl hydroperoxide (t-BHP)/Fe2+.

 Of all FAs used, the PUFAs (AA, EPA and DHA) at 40 µM concentrations reduced cell membrane integrity significantly whereas SA and OA had no effect after 72 h of incubation, suggesting the cytotoxicity of the PUF As above certain concentrations.

 This study shows that U937 cells accumulate lipid hydroperoxides, generate ethane, butane and pentane, release and incorporate AA at a greater rate in response to induced-oxidative stress by a mechanism probably involving cPLA2. In addition, AA is incorporated into cellular phospholipids at a greater rate post-oxidation. With oxidative-stress, the presence of EPA but not DHA in cellular phospholipids significantly increases the accumulation of AA in the extracellular fluid.

 Studies revealed that under oxidative-stress α-tocopherol is a potent antioxidant markedly inhibiting AA-release but not its uptake. Whilst ascorbic acid appeared to promote AA release, β-carotene and astaxanthin conferred no protective effect. Collectively, this study demonstrates the potency of α-tocopherol, ascorbic acid, β-carotene and astaxanthin against oxidant-induced peroxidative damage, AA release/uptake and ultimately total loss of cell-viability. In EPA-pretreated cells, AA-release is enhanced with/without oxidant activation suggesting its action by stimulating the availability of AA possibly for prostaglandin production.

A Minimal Model for Neutral Naturalness and pseudo-Nambu-Goldstone Dark Matter

description: We outline a scenario where both the Higgs and a complex scalar dark matter candidate arise as the pseudo-Nambu-Goldstone bosons of breaking a global $SO(7)$ symmetry to $SO(6)$. The novelty of our construction is that the symmetry partners of the Standard Model top-quark are charged under a hidden color group and not the usual $SU(3)_c$. Consequently, the scale of spontaneous symmetry breaking and the masses of the top partners can be significantly lower than those with colored top partners. Taking these scales to be lower at once makes the model more natural and also reduces the induced non-derivative coupling between the Higgs and the dark matter. Indeed, natural realizations of this construction describe simple thermal WIMP dark matter which is stable under a global $U(1)_D$ symmetry. We show how the Large Hadron Collider along with current and next generation dark matter experiments will explore the most natural manifestations of this framework.

description: We exploit a gauge invariant approach for the analysis of the equations governing the dynamics of active scalar fluctuations coupled to the fluctuations of the metric along holographic RG flows. In the present approach, a second order ODE for the active scalar emerges rather simply and makes it possible to use the Green's function method to deal with (quadratic) interaction terms. We thus fill a gap for active scalar operators, whose three-point functions have been inaccessible so far, and derive a general, explicitly Bose symmetric formula thereof. As an application we compute the relevant three-point function along the GPPZ flow and extract the irreducible trilinear couplings of the corresponding superglueballs by amputating the external legs on-shell.

title: The future of biomass as a renewable energy resource in the Czech Republic: the case of waste wood
Creators: name: Jehlickova, Bohumira
Publisher: name: The Open University
Year: 2003

description: The aim of my study was to determine the potential of waste wood as a significant household renewable energy resource that could improve the quality of the environment in the Czech Republic, particularly in the Black Triangle, the most environmentally damaged region in the country. This topic has so far received little attention, despite recent policy development at promoting renewable energy resources.

First it was necessary to establish whether there was sufficient availability of sustainably obtained waste wood. The second question was availability of suitable technology designed for efficient and environmentally friendly combustion of wood. Once these two basic requirements were determined my research followed two goals. First the dissertation aimed to identify factors and influences that play a significant role in the process in which individuals make their decision about the use of wood as a renewable fuel. There were strong reasons to anticipate that people in the Black Triangle who decided to switch to wood as a source of domestic heating in the early 1990s, were led primarily by their environmental beliefs. This hypothesis was not confirmed, although it was found that to a certain degree they were influenced by their environmental attitudes.

The outcomes of the examination of users’ experiences with fuel wood identified important barriers to its use as a domestic fuel. The newly emerging government policy was identified as a possible answer to some of the problems arising from this method of household heating in the Czech Republic. The government policy relating to promoting biomass-based renewable energy resources was thoroughly examined. Evidence was found that wood as a fuel has been mostly promoted through financial incentives and dissemination of information.

It was found that availability of wood is an issue that has to be tackled at a local level and in a complex way to ensure that there will be enough fuel in the future for large industrial users, as well as individual users. If combustion of wood is to be environmentally benign method of household heating, several conditions need to be met including the use of specially designed appliances and of wood with water content approximately 20 per cent. Some evidence was found that users do not use the fuel of a suitable quality and consequently pollute the environment.

It was suggested that local authorities’ involvement might be instrumental for disseminating know-how for keeping the users informed about environmental consequences of their behaviour as well as providing help with procurement of wood.

description: The variance of soybean futures prices is more than thirty percent higher early and late in the trading day than during the middle of the day. The pattern may be caused by patterns in information arrival or by noise introduced by the very process of trading. In empirical tests, higher variance early in the day is found to be related to information released while the market is closed. Higher variance near the end of the day is found to be unrelated to information effects, but there is evidence that it is due to trading noise.

description: The quality of recommendations based on any class of recommender systems may become poor if no or low quality data has been provided by users. This is a situation known as Cold Start problem, which typically happens when a new user registers to the system and no preference data is available for that user. Trust-Aware Recommendation Systems can be considered as a solution for the cold start problem. In these systems, the trust between users plays an import role for making recommendations. However, most of the Trust-Aware RSs consider trust as a context independent phenomenon which means if user a trusts user b to the degree k then user a trusts user b to the degree k in all the concepts. However, in reality, trust is context dependent and user a can trust user b in context X but not in Y . Moreover, most of the trust-aware RSs do not consider an expertise concept for users and all the users are considered as same in the recommendation process. In this paper we proposed a novel approach for detecting expert users just based on their ratings (unlike previous systems which consider the separate profile and extra information for each user to find an expert). In this model a supervised random walk is exploited to search the trust network for finding experts. Empirical experiments on the Epinions dataset shows that EXTRA can outperform previous models in terms of accuracy and coverage

description: The aim of this paper is to investigate and analyze the factors that have a positive impact on the stabilization of the development of dairy cattle breeding, in particular the influence of the intensity of feed costs on the efficiency of dairy farms. The current state of dairy cattle breeding development is analyzed on the example of Ukraine; in particular the assessment of influence of the intensity of feed costs on economic efficiency of dairy farms in a chosen region is summarized on the example Kharkiv region. The economic database of the 100 dairy farms located in Kharkiv region was used as the basis. Dairy farms were classified into five groups according to the level of payback on milk costs and also by the cost of feed per 1 cow. The key factors that determine unprofitableness of production are identified, on the one hand; and the factors that affecting on the stabilization of dairy cattle breeding, on the other hand. Results of the grouping of milk farms and correlation analysis confirmed the hypothesis about the positive impact of increasing feed costs per 1 cow on the level of productivity of cows. The problems connected with the decrease in the payback of additional feed costs, which must be taken into account when determining the strategy for the development of dairy cattle farming for the future, have been clarified.

description: The molecular dipole moment ($\boldsymbolμ$) is a central quantity in chemistry. It is essential in predicting infrared and sum-frequency generation spectra, as well as induction and long-range electrostatic interactions. Furthermore, it can be extracted directly from high-level quantum mechanical calculations, making it an ideal target for machine learning (ML). In this work, we choose to represent this quantity with a physically inspired ML model that captures two distinct physical effects: local atomic polarization is captured within the symmetry-adapted Gaussian process regression (SA-GPR) framework, which assigns a (vector) dipole moment to each atom, while movement of charge across the entire molecule is captured by assigning a partial (scalar) charge to each atom. The resulting "MuML" models are fitted together to reproduce molecular $\boldsymbolμ$ computed using high-level coupled-cluster theory (CCSD) and density functional theory (DFT) on the QM7b dataset. The combined model shows excellent transferability when applied to a showcase dataset of larger and more complex molecules, approaching the accuracy of DFT at a small fraction of the computational cost. We also demonstrate that the uncertainty in the predictions can be estimated reliably using a calibrated committee model. The ultimate performance of the models depends, however, on the details of the system at hand, with the scalar model being clearly superior when describing large molecules whose dipole is almost entirely generated by charge separation. These observations point to the importance of simultaneously accounting for the local and non-local effects that contribute to $\boldsymbolμ$; further, they define a challenging task to benchmark future models, particularly those aimed at the description of condensed phases.

Alternative binders to simplify the recycling of lithium-ion batteries

Subjects: Uncategorized

description: Binders are a vital component in the structure and function of battery electrodes. They do, however, have implications for the lifetime and recyclability or lithium ion batteries.
This project identified several alternative binders that could simplify battery disassembly during end-of-life processing. Primarily anode binders were investigated, and it was found that water-miscible biopolymers, sodium alginate and gelatin, allowed complete delamination of the electrode active material from the current collector using lowpowered ultrasound with water in 5 seconds. Modification of these polymers, with a deep eutectic solvent made from choline chloride and glycerol, also allowed for the enhancement of key properties such as the thermal stability, adhesive strength and, in the case of sodium alginate, the electrochemical stability of the cells at high cycling rates.
Other polymer systems were also tested as binders to try and optimise other key characteristics of the anodes, such as the use of polyaniline and sodium alginate to form a polymer blend. Anodes created using these polymer blends found that the conductivity increased with polyaniline content, but other factors such as a poorer adhesive strength was observed.
Alternative extracellular adhesives and pack designs were also discussed, where a novel pack structure using a zigzag conformation of the cells joined together with pressure sensitive adhesives such as glue dots. This was shown to significantly reduce disassembly time and create a simplified dismantling procedure that could be easier to automate, increasing the economic viability of battery disassembly versus conventional end-of-life processes like shredding. This study included an environmental impact study comparing battery disassembly steps when alternative adhesives were used in both electrode binders and extracellular adhesives. These were then compared to commercial standards. This showed a 200% reduction in the global warming potential of the overall recycling process highlighting the importance of design for recycle for LIBs benefits, in terms of performance, economic viability of disassembly and environmental impact.

description: We discuss a new approach to putting supersymmetric theories on the lattice. The basic idea is to start from a {\it twisted} formulation of the underlying supersymmetric theory in which the fermions are represented as grassmann valued antisymmetric tensor fields. The original supersymmetry algebra is replaced by a twisted algebra which contains a scalar nilpotent supercharge $Q$. Furthermore the action of the theory can then be written as the $Q$-variation of some function. The case of ${\cal N}=2$ super Yang-Mills theory in two dimensions is discussed in some detail. We then present our proposal for discretizing this theory and derive the resultant lattice action. The latter is local, free of spectrum doubling, gauge invariant and preserves the scalar supercharge invariance exactly. Some preliminary numerical results are then presented. The approach can be naturally generalized to yield a lattice action for ${\cal N}=4$ super Yang-Mills in four dimensions.

description: The present study attempts to estimate the extent of contributions of various factor to the yield gap in cotton in Raichur district (Karnataka), with the help of decomposition analysis. The study was based on the cross section data from 120 randomly selected cotton growing farmers, besides the relevant demonstration data in the study area. The data pertain to the crop year 1987-88. the estimated yield gap in cotton ind the study area was found to be more than 50 per cent. Inappropriate techniques of production adopted by large farmers and sub-optimal input use by small farmers were found to contribute significantly to the estimated yield gap in cotton. Intensification of extension education activities for larger farmers and liberal credit policy to acquire the needed critical inputs for small farmers would help in exploiting the yield potential in cotton in the study area.

description: Accurate segmentation of skin lesion from dermoscopic images is a crucial part of computer-aided diagnosis of melanoma. It is challenging due to the fact that dermoscopic images from different patients have non-negligible lesion variation, which causes difficulties in anatomical structure learning and consistent skin lesion delineation. In this paper, we propose a novel bi-directional dermoscopic feature learning (biDFL) framework to model the complex correlation between skin lesions and their informative context. By controlling feature information passing through two complementary directions, a substantially rich and discriminative feature representation is achieved. Specifically, we place biDFL module on the top of a CNN network to enhance high-level parsing performance. Furthermore, we propose a multi-scale consistent decision fusion (mCDF) that is capable of selectively focusing on the informative decisions generated from multiple classification layers. By analysis of the consistency of the decision at each position, mCDF automatically adjusts the reliability of decisions and thus allows a more insightful skin lesion delineation. The comprehensive experimental results show the effectiveness of the proposed method on skin lesion segmentation, achieving state-of-the-art performance consistently on two publicly available dermoscopic image databases.

description: The supply response of cotton in three regions viz., Costal Andhra, Rayalaseema and Telangana of Andhra Pradesh was assessed by applying a Nerlovian Lagged Adjustment Model for area, production and yield separately. The results revealed that in general the farmers' area and resource allocation decisions for cotton was influenced by its own price. In case of Rayalaseema, the price of competing crop had negative impact on area while price risk surprisingly exerted positive influence on yield. These results imply that the farmers' area and resource allocation decisions for cotton could be influenced through remunerative price policies. The supply response is also found to be influenced by traditional behaviour of farmers in allocating the area and resources for cotton cultivation. The price elasticities indicated that the growers in Coastal Andhra are more price conscious than in the other two regions. The adjustment mechanism showed that the Coastal Andhra required less number of years for production and yield adjustments while area adjustment is quick in Rayalaseema region.

description: It is well known that in classical optics, the visibility of interference, in a two-beam light interference, is related to the optical coherence of the two beams. A wave-particle duality relation can be derived using this mutual coherence. The issue of wave-particle duality in classical optics is analyzed here, in the more general context of multipath interference. New definitions of interference visibility and path distinguishability have been introduced, which lead to a duality relation for multipath interference. The visibility is shown to be related to a new multi-point optical coherence function.

description: While social networks such as Facebook and Twitter are censored within the Iranian network, the number of Iranian users that use such services is facing an outsized growth. As a result, an increasing number of Iranian users have taken the habit of using some type of anti-censorship tool to access blocked content, which is an act against the Iranian ICT laws by itself. At the same time, each year numerous cases of identity theft, robberies, harassment and alike are reported in countries such as United States that happen due to both technical glitches/misconfigurations by the service provider and the inconsiderate behavior of users when using those services. As a matter of fact, countries such as UK and US are making efforts to increase peoples’ awareness about required security and privacy precautions and enact laws that support user’s right of having online security and privacy. However, relevant literature review indicates that the Iranian authorities are mainly focusing on preventing and discouraging the use of social network tools and are unwilling to accept the increasing usage yet. In this paper we present our survey results among 511 Facebook users residing in Iran, which shows that Iranian users have a very limited knowledge about potential privacy and security risks of using anti-censorship tools and online social networks such as Facebook. We conduct a risk analysis based on surveyed facts and suggest recommendations on how to improve this condition.

description: In a previous paper, we have shown that it was possible to use the DGLAP evolution equatio n to constrain the high-$Q^2$ ($Q^2 \ge 10$ GeV$^2$) behaviour of the residues of a high-e nergy Regge model, and we applied the developed method to the triple-pole pomeron model. W e show here that one can obtain a description of the low-$Q^2$ $γ^{(*)} p$ data match ing the high-$Q^2$ results at $Q^2 = 10$ GeV$^2$.

description: We have numerically studied the instability of the spherically symmetric standing accretion shock wave against non-spherical perturbations. We have in mind the application to the collapse-driven supernovae in the post bounce phase, where the prompt shock wave generated by core bounce is commonly stalled. We take an experimental stand point in this paper. Using spherically symmetric, completely steady, shocked accretion flows as unperturbed states, we have clearly observed both the linear growth and the subsequent nonlinear saturation of the instability. In so doing, we have employed a realistic equation of state together with heating and cooling via neutrino reactions with nucleons. We have done a mode analysis based on the spherical harmonics decomposition and found that the modes with l=1, 2 are dominant not only in the linear regime, but also after the nonlinear couplings generate various modes and the saturation occurs. Varying the neutrino luminosity, we have constructed the unperturbed states both with and without a negative entropy-gradient. We have found that in both cases the growth of the instability is similar, suggesting the convection does not play a dominant role, which also appears to be supported by the recent linear analysis of the convection in accretion flows by Foglizzo et al. The real part of the eigen frequency seems to be mainly determined by the advection time rather than by the sound-crossing time. Whatever the cause may be, the instability is favorable for the shock revival.

description: A set of natural numbers tiles the plane if a square-tiling of the plane exists using exactly one square of side length n for every n in the set. From [2] we know that N itself tiles the plane. From that and [3] we know that the set of even numbers tiles the plane while the set of odd numbers does not. According to [1] it is possible to tile the plane using only an odd square. In this paper we will check that if it is possible to tile the plane using an even set and n odd numbers or not.

description: In software rating area, it is necessary to apply a measurement reference model to evaluate the quality of software. The standard 25030 is an example of an evaluation system which is based on stakeholders' requirements. In this study, an attempt has been made to establish a model in which all implicit and explicit requirements of stakeholders, users and policy makers have been taken into account. In addition, AHP method has been followed to weigh the indicators used in the model. The results show applicability of the model to meet the requirements of Iranian users.

description: We study the electronic densities of states (DOS) of strongly disordered superconducting thin films of TiN. We find, using Scanning Tunneling Microscopy (STM) that the DOS decreases towards the Fermi level in the normal phase obtained by applying magnetic fields. The DOS shows spatial fluctuations whose length scale is related to the energy dependent DOS and is similar in normal and superconducting phases. This suggests that Coulomb interactions lead to a spatially varying DOS in the normal phase of a disordered superconductor.

description: Two-dimensional multi-valley electronic systems in which the dispersion of individual pockets has low symmetry give rise to quantum Hall ferroelectric and nematic states in the presence of strong quantising magnetic fields. We investigate local signatures of these states arising near impurities that can be probed via Scanning Tunnelling Microscopy (STM) spectroscopy. For quantum Hall ferroelectrics, we demonstrate a direct relation between the dipole moment measured at impurity bound states and the ideal bulk dipole moment obtained from the modern theory of polarisation. We also study the many-body problem with a single impurity via exact diagonalization and find that near strong impurities non-trivial excitonic state can form with specific features that can be easily identified via STM spectroscopy.
