description: ‘It’s so much better when we all listen to each other’: Exploring the impact of implementing a restorative approach within a primary school setting. Scotland is an unequal society. This is illustrated through health and social measures, and the persistent gap in educational attainment between the richest and poorest households in Scotland. As a result, there is a focus on promoting equitable education within Scotland. The current research explored the impact of implementing a restorative approach in the context of promoting equitable education. A restorative approach has a relational focus and supports development of social and emotional skills and conflict resolution. Two strands run throughout the research, firstly, a focus on implementation and secondly, embedding restorative approaches within a whole school setting. Through a mixed methods design, the impact on pupils and school staff is considered, with a specific focus on relationships, school ethos and conflict resolution skills. Social networks of both pupils and staff were examined during the research through social network analysis. Results of the study demonstrated positive impact in relation to several factors, including agency, autonomy and affiliation for pupils and staff, improved relationships across the school and improved problem solving and skills in conflict resolution. Furthermore, there was a positive increase in academic attainment within the school. In addition to positive results, the research process supported the development of an implementation guide to support schools with whole school implementation of restorative approaches in a Scottish context.
A cross-sectional study was undertaken with the aim of estimating the prevalence, identifying parasite species and assessing associated risk factors for the occurrence of haemoparasites in indigenous and cross breeds backyard chickens in selected districts of West Gojjam zone, Amhara region, Ethiopia from October 2016- May 2017. A total of 384 blood samples were collected and examined for the presence of haemoparasites using thin blood films. Out of these samples, 71 (18.5 %) of them were infected with haemoparasites. Four species of haemoparasites were identified, namely Aegyptienella spp., Haemoproteus spp., Leucocytozoon spp. and Plasmodium spp.. Highest prevalence of haemoparasite infection was recorded in midland (22.3%) compared to highland (10.9 %) areas with a statistical significant difference (p<0.05) between them. Statistical significance variation (p<0.05%) was observed in haemoparasite infection among districts, with highest prevalence in S/Achefer (27.3%) followed by B/Zuria (17.2 %) and the lowest in Mecha (10.9%) districts. Age and management system of chickens were significantly associated (p<0.05) with haemoparasite infection. While sex and breed did not show significant difference between their counter parts. Based on haematological analysis, red blood cell count and level of hemoglobin was showed a statistical significant (p<0.05) difference between infected and non-infected chickens. The results obtained in this study suggested that haemoparasite infection in chickens is prevalent in the study area. Hence, appropriate control measures should be implemented to solve the existing problem.

Programming of adult metabolic phenotype by maternal dietary folic acid and vitamin B12 imbalance in mice
Creators: name: Aleliunas, Rika
Publisher: name: University of British Columbia
Year: 2013

description: Prenatal and early postnatal nutrient status influences metabolic health in adulthood. A study from India reported that children born to women with high folate and low vitamin B12 status during pregnancy had increased adiposity and insulin resistance. Many countries, including Canada, fortify their grain products with folic acid. In Canada, women have adequate folate status but 1 in 20 may be vitamin B12 deficient. Currently, the metabolic consequences of developmental exposure to high folic acid, with or without vitamin B12 deficiency, are unknown. Female C57BL/6J mice were fed diets high in folic acid, with (HFA+B12) and without (HFA-B12) adequate vitamin B12, or a control diet throughout breeding, pregnancy and lactation. Offspring were weaned onto a control or western-type diet (WTD) for 30 weeks. Maternal and post-weaning diets affected visceral (P<0.01) and subcutaneous fat accumulation (P<0.05) at 20 weeks post-weaning. An interaction between maternal and post-weaning diet was observed in the retroperitoneal fat depot; WTD-fed mice with developmental exposure to HFA-B12 and HFA+B12 diets had decreased retroperitoneal fat accumulation relative to those exposed to maternal control diet. Maternal and post-weaning diets interacted at 30 weeks post-weaning to modify fasting insulin concentrations; in control-fed mice, those with developmental exposure to HFA-B12 had increased fasting insulin concentrations (P<0.05) relative to those with exposure to maternal control and HFA+B12 diets. Maternal and post-weaning diets interacted to affect vascular function of the mesenteric artery at 20 weeks post-weaning. Endothelium-mediated smooth muscle relaxation was decreased in WTD-fed mice with developmental exposure to HFA-B12 diet relative maternal control and HFA+B12 diet-exposed groups (P<0.05). Control-fed mice with developmental exposure to HFA-B12 and HFA+B12 diet had decreased mesenteric artery basal nitric oxide production relative to maternal controls (P<0.05). Developmental exposure to high folic acid (with and without vitamin B12) was associated with decreased NADPH oxidase subunit expression in the aorta (P<0.05). These findings demonstrate that developmental exposure to folic acid and vitamin B12 imbalance interacts with post-weaning diet to program the metabolic response in adult mice. Further studies are warranted to determine the mechanisms behind such effects and to determine the need for vitamin B12 supplementation during pregnancy.

description: In the present work, we examine "binary" waveguide arrays, where the coupling between adjacent sites alternates between two distinct values $C_1$ and $C_2$ and a saturable nonlinearity is present on each site. Motivated by experimental investigations of this type of system in fabricated LiNbO$_3$ arrays, we proceed to analyze the nonlinear wave excitations arising in the self-defocusing nonlinear regime, examining, in particular, dark solitons and bubbles. We find that such solutions may, in fact, possess a reasonably wide, experimentally relevant parametric interval of stability, while they may also feature both prototypical types of instabilities, namely exponential and oscillatory ones, for the same configuration. The spectral properties of the linearization around the solutions and the presence of two bands and associated mini-gaps are discussed and the nontrivial differences from the standard cubic discrete nonlinear Schr{ö}dinger model are highlighted.

description: In this Letter we use the Julia-Toulouse approach for condensation of defects in order to obtain an effective confinement theory for external chromoelectric probe charges in SU(3) gauge theory in the regime with condensed chromomagnetic monopoles. We use the Cho decomposition of the non-Abelian connection in order to reveal the Abelian sector of the non-Abelian gauge theory and the associated topological defects (monopoles) without resorting to any gauge fixing procedure. Using only the Abelian sector of the theory, we construct a hydrodynamic effective theory for the regime with condensed defects in such a way that it is compatible with the Elitzur's theorem. The resulting effective theory describes the interaction between external chromoelectric probe charges displaying a short-range Yukawa interaction plus a linear confining term that governs the long distance physics.

description: Centralized storage and exchange of data is a key issue of interdisciplinary research projects particularly if they focus on environmental field studies and regional modelling. Furthermore, the overall success of such projects depends on a well organized data management and data exchange between all involved disciplines. This includes the organization of data, the implementation of a database and the maintenance of such a system for intensive data exchange between the project sections. This paper presents the implementation of a centralized data management system for the Transregional Collaborative Research Centre 32: 'Patterns in Soil-Vegetation-Atmosphere Systems: Monitoring, Modelling, and Data Assimilation' funded by the German Research Foundation. The design is a combination of file management, database, and online-interface including web mapping functionalities.

description: We use ATLAS and CMS searches in the mono-jet + missing energy and mono-photon + missing energy final state to set limits on the couplings of dark matter to quarks and gluons. Working in an effective field theory framework we compare several existing mono-jet analyses and find that searches with high p_T cuts are more sensitive to dark matter. We constrain the suppression scale of the effective dark matter-Standard Model interactions, and convert these limits into bounds on the cross sections relevant to direct and indirect detection. We find that, for certain types of operators, in particular spin-independent dark matter-gluon couplings and spin-dependent dark matter-quark couplings, LHC constraints from the mono-jet channel are competitive with, or superior to, limits from direct searches up to dark matter masses of order 1 TeV. Comparing to indirect searches, we exclude, at 90% C.L., dark matter annihilating to quarks with the annihilation cross section of a thermal relic for masses below ~ 15-70 GeV, depending on the Lorentz structure of the effective couplings. Mono-photon limits are somewhat weaker than mono-jet bounds, but still provide an important cross check in the case of a discovery in mono-jets. We also discuss the possibility that dark matter--Standard Model interactions at LHC energies cannot be described by effective operators, in which case we find that constraints can become either significantly stronger, or considerably weaker, depending on the mass and width of the intermediate particle. We also discuss the special case of dark matter coupling to the Higgs boson, and we show that searches for invisible Higgs decays would provide superior sensitivity, particularly for a light Higgs mass and light dark matter.

description: Monitoring and modeling projects usually involves time series data originating from different sources. Often, file formats, temporal resolution, and metadata documentation rarely adhere to a common standard. As a result, much effort is spent on converting, harmonizing, merging, checking, resampling, and reformatting these data. Moreover, in work groups or during the course of time, these tasks tend to be carried out redundantly and repeatedly, especially when new data becomes available. The resulting duplication of data in various formats strains additional resources. We propose a database structure and complementary scripts for facilitating these tasks. The GOLM- (General Observation and Location Management) framework allows import and storage of time series data of different types while assisting metadata documentation, plausibility checking and harmonization. The imported data can be visually inspected and its coverage among locations and variables may be visualized. Supplementing scripts provides options for data export of selected stations and variables and resampling of the data to the desired temporal resolution. These tools can, for example, be used for generating model input files or reports. Since GOLM fully supports network access, the system can be used efficiently by distributed working groups accessing the same data over the internet. GOLMs database structure and the complementary scripts can easily be customized to specific needs. Any involved software such as MySQL, R, PHP, OpenOffice as well as the scripts for building and using the data base, including documentation, are free for download. GOLM was developed out of the practical requirements of the OPAQUE-project. It has been tested and further refined in the ERANET-CRUE and SESAM projects, which all used GOLM to manage meteorological, hydrological and/or water quality data.

The algebraic setting allows their full characterization (explicit expressions, recurrence relations, difference equations, generating functions, etc.) of those polynomials. In the limit where su(2) contracts to the Heisenberg-Weyl algebra h_1, these polynomials tend to the standard Meixner polynomials and d-Charlier polynomials, respectively.

description: Stokes waves are steady periodic water waves on the free surface of an infinitely deep irrotational two dimensional flow under gravity without surface tension. They can be described in terms of solutions of the Euler-Lagrange equation of a certain functional. This allows one to define the Morse index of a Stokes wave. It is well known that if the Morse indices of the elements of a set of non-singular Stokes waves are bounded, then none of them is close to a singular one. The paper presents a quantitative variant of this result.

description: The expansion of a stochastic Liouville equation for the coupled evolution of a quantum system and an Ornstein-Uhlenbeck process into a hierarchy of coupled differential equations is a useful technique that simplifies the simulation of stochastically-driven quantum systems. We expand the applicability of this technique by completely characterizing the class of diffusive Markov processes for which a useful hierarchy of equations can be derived. The expansion of this technique enables the examination of quantum systems driven by non-Gaussian stochastic processes with bounded range. We present an application of this extended technique by simulating Stark-tuned Förster resonance transfer in Rydberg atoms with non-perturbative position fluctuations.

description: In this work we consider triangulations of point sets in the Euclidean plane, i.e., maximal straight-line crossing-free graphs on a finite set of points. Given a triangulation of a point set, an edge flip is the operation of removing one edge and adding another one, such that the resulting graph is again a triangulation. Flips are a major way of locally transforming triangular meshes. We show that, given a point set $S$ in the Euclidean plane and two triangulations $T_1$ and $T_2$ of $S$, it is an APX-hard problem to minimize the number of edge flips to transform $T_1$ to $T_2$.

description: We derive a set of first-order differential equations obeyed by the S-matrix of planar maximally supersymmetric Yang-Mills theory. The equations, based on the Yangian symmetry of the theory, involve only finite and regulator-independent quantities and uniquely determine the all-loop S-matrix. When expanded in powers of the coupling they give derivatives of amplitudes as single integrals over lower-loop, higher-point amplitudes/Wilson loops. We outline a derivation for the equations using the Operator Product Expansion for Wilson loops. We apply them on a few examples at two- and three-loops, reproducing a recent result on the two-loop NMHV hexagon and fixing previously undermined coefficients in a recent Ansatz for the three-loop MHV hexagon. In addition, we consider amplitudes restricted to a two-dimensional subspace of Minkowski space and derive a particularly simple set of partially closed equations in that case.

description: For any C1 expanding map f of the circle we study the equilibrium states for the potential -log |f'|. We formulate a C1 generalization of Pesin's Entropy Formula that holds for all the SRB measures if they exist, and for all the (necessarily existing) SRB-like measures. In the C1-generic case Pesin's Entropy Formula holds for a unique SRB measure which is not absolutely continuous with respect to Lebesgue. The result also stands in the non generic case for which no SRB measure exists.

description: In this paper we present a concept for the storage, exchange, presentation, and analysis of geospatial, environmental, and archaeological data with the aim to study and assess the dynamics of early human expansion. We present geographic information systems (GIS), database solutions and web based technologies for handling and processing archaeological and physiographic information. The project deals with a range of variables and file formats from the fields of geology, geomorphology, paleontology, and archaeology presented in vector, raster, and text formats. In order to demonstrate the possibilities of the ROCEEH Out of Africa Database (ROAD), this study presents a unique set of archaeological information sampled from a period between 3Ma and 20Ka covering the region of Southern Africa. The data includes site locations, their geology, and most important, the archaeological, paleo-biological, and climatic data that are accessed for these different locations. To help explaining the spatial distribution of archaeological and paleontological sites, detailed topographic information was provided at scales of 5m, 10m, 25m, 90m, and 1km based on aerial photography, ASTER, and SRTM elevation data. Moreover, bathymetry was provided at a resolution of 1km. Combining these data sets, we show the first spatial and conceptual analysis of the data using ROAD. The results of different research questions show the potential of these methods and give some perspectives for future applications.

Prenatal alcohol exposure programs steady-state gene expression and the gene expression response to inflammation in the adult rat brain
Creators: name: Stepien, Katarzyna Anna
Publisher: name: University of British Columbia
Year: 2013

description: Prenatal alcohol exposure results in alterations in numerous physiological systems, including neuroendocrine and neuroimmune systems. The purpose of this study was to determine whether prenatal ethanol exposure results in long-term alteration of neural gene expression, particularly in genes related to neuroendocrine and neuroimmune function. Utilizing a well-established animal model of prenatal ethanol exposure, ethanol was administered to pregnant Sprague-Dawley dams throughout gestation in a liquid diet fed ad libitum (36% calories derived from ethanol). Maltose-dextrin was isocalorically substituted for ethanol in a liquid control diet for a pair-fed group, and a control group received a pelleted control diet ad libitum. In young adulthood, an adjuvant-induced arthritis paradigm was utilized, where female offspring were injected with either saline or complete Freund’s adjuvant, to induce an inflammatory response and elucidate dysregulated neuroimmune pathways. Gene expression was analyzed in the prefrontal cortex and hippocampus at both the peak and resolution of arthritis using whole genome gene expression microarrays. Within saline-injected animals, prenatal alcohol exposure alone resulted in significant changes in gene expression in both the prefrontal cortex and hippocampus. Included were multiple genes related to, cell death, transcriptional regulation, neuronal signaling and neurodevelopment. Among the genes involved in neurodevelopment, Acs13 has also been shown to be variably methylated in humans according to in utero exposure to environmental factors. Prenatal alcohol exposure also altered the gene expression response to adjuvant-induced arthritis. Many genes showed a significantly different pattern of expression in ethanol-exposed animals compared to both pair-fed and control, in both prefrontal cortex and hippocampus. These genes were either differentially up- or downregulated in ethanol-exposed compared to control animals or failed to show the adjuvant-induced change in regulation shown by controls. As well, several of these genes were mediators of the response to immune or stress challenge, such as Lcn2 and Bhlhe40. Genes found to be differentially expressed in this study are potential mediators contributing to the long-term alterations in neuroendocrine and neuroimmune function observed in prenatal alcohol exposure.

description: An isolated quantum many-body system in an initial pure state will come to thermal equilibrium if it satisfies the eigenstate thermalization hypothesis (ETH). We consider alternatives to ETH that have been proposed. We first show that von Neumann's quantum ergodic theorem relies on an assumption that is essentially equivalent to ETH. We also investigate whether, following a sudden quench, special classes of pure states can lead to thermal behavior in systems that do not obey ETH, namely, integrable systems. We find examples of this, but only for initial states that obeyed ETH before the quench.

In the energy range MGUT-MZ where supergravity effects can be ignored, it is proposed that such DM particle could be interpreted in terms of a mixture of Bino and Wino states with a lower bound mass MDM sup or eq to 65GeV not far above the electroweak scale to account for the observed Dark Matter density. We establish the theoretical origin of this particle and study as well its compositeness and its mass bound.

description: В данной статье рассматривается расселение эстонцев по территории Новгородской губернии с 1868 (начало переселения) по 1927 г. (ликвидация Новгородской губернии). Переселение эстонцев в Новгородскую губернию было связано с тяжелым социально-экономическим положением крестьян в Остзейском крае Российской империи – дефицитом свободной земли и высокой арендной платой. Губернские власти содействовали
переселению, оказывая материальную помощь эстонским колонистам. В основном прибалтийские переселенцы образовывали хутора, объединявшиеся в колонии, на арендуемых у дворян землях. Основными очагами расселения эстонцев в Новгородской губернии стали Крестецкий, Новгородский и Демянский уезды. Наибольшее количество эстонских колоний было организовано в 1880 – начале 1910-х гг. К 1927 г. их количество
достигло 34.

description: Working with 108,786 Sloan Digital Sky Survey low redshift galaxies we have examined the relation between galaxy mass, metallicity, radius, and star formation rates primarily in the central portions of galaxies. We subdivided the redshift range covered in our sample, 0.07 2.0x10^10 Msun and large radii appear fed by infall. Smaller massive galaxies with high Zx and high star formation rates show more complex behavior. A mean-field-theory toy model for the physics of infall accounts for the (SFR) \propto Mi^(3/2) relation and permits us to estimate the mean densities and velocities of clumps of baryonic matter traversing the dark matter halos in which the SDSS galaxies may be embedded.

description: In this paper, linear transceiver design for multi-hop amplify-and-forward (AF) multiple-input multiple-out (MIMO) relaying systems with Gaussian distributed channel estimation errors is investigated. Commonly used transceiver design criteria including weighted mean-square-error (MSE) minimization, capacity maximization, worst-MSE/MAX-MSE minimization and weighted sum-rate maximization, are considered and unified into a single matrix-variate optimization problem. A general robust design algorithm is proposed to solve the unified problem. Specifically, by exploiting majorization theory and properties of matrix-variate functions, the optimal structure of the robust transceiver is derived when either the covariance matrix of channel estimation errors seen from the transmitter side or the corresponding covariance matrix seen from the receiver side is proportional to an identity matrix. Based on the optimal structure, the original transceiver design problems are reduced to much simpler problems with only scalar variables whose solutions are readily obtained by iterative water-filling algorithm. A number of existing transceiver design algorithms are found to be special cases of the proposed solution. The differences between our work and the existing related work are also discussed in detail. The performance advantages of the proposed robust designs are demonstrated by simulation results.

description: We present and derive analytic expressions for a fundamental limit to the sympathetic cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work done by the trap electric field during a long-range ion-atom collision and applies even to cooling by a zero-temperature atomic gas in a perfectly compensated trap. We conclude that in current experimental implementations this collisional heating prevents access to the regimes of single-partial-wave atom-ion interaction or quantized ion motion. We determine conditions on the atom-ion mass ratio and on the trap parameters for reaching the s-wave collision regime and the trap ground state.

description: In this study, we examine how electronic payment systems (EPS) could help low-income areas get accessto traditional banking services. This research looks at how EPS like mobile money, internet banking, anddigital wallets help underserved areas get access to banking services. Expanding access to financialservices, enhancing efficiency, and getting more people participating in the economy are just a few of thepossible benefits of EPS. On the other hand, there are a few negatives, including as cybersecurity risks,poor infrastructure, and low levels of digital literacy. It is a global priority to guarantee that all people andcompanies may get their hands on adequate, affordable, and prompt financial services. A sizable portion ofthe population in developing countries either does not have access to or has insufficient bank accounts dueto factors such as geographical isolation, poverty, and a lack of infrastructure for traditional banking.Keywords — Agricultural engineering, Harvesting technology, Multi-cropharvesting, Combine harvester,Agricultural machinery, Precision farming

description: Interdisciplinary research approaches have to run integrative data analyses to realize their full potential. In biodiversity research, the range of relevant disciplines is large, comprising for instance point related genetical analysis, meteorologists covering three-dimensional energy fluxes, and ecologist working on a landscape level. Each discipline employs specific file formats, data syntax, and concepts or terminology, rendering a joint analysis challenging. A successful central data management must be able to harmonize data across disciplines. A necessary condition is the appropriate annotation of primary data with metadata. A sufficient condition is the formalization of the implicit knowledge about data, its semantics. This paper outlines a framework enabling a knowledge-based data and tool access within the Biodiversity Exploratory Information System (BExIS). We address the problem of semantic heterogeneity within the data sets by relating all data items to concepts of a common, upper-level ontology which reflects the relationships between individual ecological topics. The frameworks service oriented architecture allows for seamless integration of external data sources and analysis tools. We describe the idea of ontologybased data and tool access, the framework concept and its service-oriented architecture as well as the process of semantic registration of data, and provide some details on our implementation as well as a discussion of first experiences with this framework.

description: A commonly cited drawback of SPH is the introduction of spurious shear viscosity by the artificial viscosity term in situations involving rotation. Existing approaches for quantifying its effect include approximate analytic formulae and disc-averaged be- haviour in specific ring-spreading simulations, based on the kinematic effects produced by the artificial viscosity. These methods have disadvantages, in that they typically are applicable to a very small range of physical scenarios, have a large number of simplifying assumptions, and often are tied to specific SPH formulations which do not include corrective (e.g., Balsara) or time-dependent viscosity terms. In this study we have developed a simple, generally applicable and practical technique for evaluating the local effect of artificial viscosity directly from the creation of specific entropy for each SPH particle. This local approach is simple and quick to implement, and it al- lows a detailed characterization of viscous effects as a function of position. Several advantages of this method are discussed, including its ease in evaluation, its greater accuracy and its broad applicability. In order to compare this new method with ex- isting ones, simple disc flow examples are used. Even in these basic cases, the very roughly approximate nature of the previous methods is shown. Our local method pro- vides a detailed description of the effects of the artificial viscosity throughout the disc, even for extended examples which implement Balsara corrections. As a further use of this approach, explicit dependencies of the effective viscosity in terms of SPH and flow parameters are estimated from the example cases. In an appendix, a method for the initial placement of SPH particles is discussed which is very effective in reducing numerical fluctuations.

description: The European Mining Database for North Rhine Westphalia (EMD-NRW) has the objective to present information about the industrial heritage of mining in a GIS-based web portal. Especially in the area of North Rhine Westphalia (Germany) larger coal reserves were important for the development of the industry and particularly influenced the landscape. Concerning the increasing abandonment of these objects and the loss of the cultural industry objects, the preservation of information and the relations between these objects is important. The EMD-NRW system is capable of representing the complex, hierarchical structure of archive data and connecting this data to their geographical location. Several technologies are used to share this information in a web portal. Therefore, comprehensive information is available about every object. All objects are spatially referenced and can be visualized in a map. It is possible to connect the system to other projects by the use of open, compliant techniques. For beginners and experts information are easy to retrieve because of an intuitive design of the graphical user interface.

description: The pressure on environmental systems is increasing worldwide due to population growth and the consequences of climate change. Adaptable tools and methods are needed to elaborate information, develop understanding and strategies for sustainable use and management of environmental systems. Such tools should assist scientists, natural resource managers, and decision makers in their work by providing (1) sufficient information about relevant drivers, attributes, and factors from measured data, (2) tools and methods for user friendly access and integrated analyses of such data, i.e. environmental information systems (EIS), and (3) tools for estimating additional information not available as measurements, i.e. environmental simulation models. In addition, a seamless and preferably standardized exchange of data between EIS and integrated assessment tools such as simulation models is gaining increasing importance as the amount of available environmental information is growing together with the complexity of current environmental challenges. The research at the Department of Geoinformatics, Hydrology and Modelling at the Friedrich Schiller University of Jena is reflecting the needs described above with the development of a number of software tools. They provide services and assistance for specific spatio-temporal related environmental problems emerging from integrated research projects. In general, all developed tools (1) use open source software wherever possible to be cost effective, (2) are provided as open source software to others, and (3) are highly flexible and adaptable to ensure usability for a wide range of environmental problems. In this paper we briefly present the River Basin Information System (RBIS)  a web-based information management system with a focus on time series and geospatial data. It provides user friendly interfaces for data input and output, powerful visualization components, and an adaptable set of functions for data analysis, data management, and data enrichment. Sample applications from various research projects are used to illustrate that RBIS is an appropriate platform to meet the demands for collaborative and integrated data management.

description: Disordered cholesterol metabolism is linked to neurodegeneration. In this study we investigated the profile of cholesterol metabolites found in the cerebrospinal fluid (CSF) of Parkinson’s disease (PD) patients. When adjustments were made for confounding variables of age and sex, 7α,(25R)26-dihydroxycholesterol and a second oxysterol 7α,x,y-trihydroxycholest-4-en-3-one (7α,x,y-triHCO), whose exact structure is unknown, were found to be significantly elevated in PD CSF. The likely location of the additional hydroxy groups on the second oxysterol are on the sterol side-chain. We found that CSF 7α-hydroxycholesterol levels correlated positively with depression in PD patients, while two presumptively identified cholestenoic acids correlated negatively with depression.

description: Information management is one important and challenging task in engineering projects. The progress in computer simulation techniques, new measurement techniques in field and laboratory as well as the access to mass of data via the Internet requires new information management strategies beyond traditional database solutions. This paper describes the information management in an ongoing research unit dealing with the coupling of flow and deformation processes for modeling the movement of natural slopes. Based on a generalized information modeling approach using sets of tensors an innovative information management system allows the handling, analysis, reporting, and archiving of any physical state variable on different time and space scale. This leads to an efficient integration/coupling of different models with related information mapping methods as well as information mining approaches for scenario and process identification.
