Auswirkungen von automatischen Gedanken und psychologischer Flexibilität auf die depressive Symptomatik und Rückfallwahrscheinlichkeit remittiert Depressiver

Hintergrund: Obwohl positive und negative automatische Gedanken (PAG, NAG) sowie die psychologische Flexibilität (PF) einen engen Zusammenhang mit der depressiven Symptomatik aufweisen, wurde die Rolle dieser Variablen bei einem depressiven Rückfall bisher nicht erforscht. Fragestellung: In dieser Studie wird untersucht, wie sich eine stationäre Intervention auf klinische Variablen (PAG, NAG und PF) auswirkt. Zudem wird der Verlauf von PAG, NAG und PF von Frührückfälligen in der Katamnesephase erforscht. Dabei geht es darum, inwiefern PAG, NAG und PF einen Rückfall vorhersagen. Methode: Bei 39 remittierten Depressiven sowie 45 gesunden Kontrollpersonen wurden die oben genannten Variablen erhoben. In der experimentellen Phase wurde bei den Probanden beider Gruppen eine traurige Stimmung induziert. Die remittiert depressiven Probanden wurden über eine 16-monatige Katamnesephase nachuntersucht. Ergebnisse: Nach der negativen Stimmungsinduktion riefen remittiert Depressive im Vergleich zu Gesunden weniger PAG ab. Zudem zeigten Frührückfällige während der Katamnesephase einen eingeschränkten Zugang zu PAG und eine niedrige PF. Weder PAG, NAG noch PF erwiesen sich als bedeutsame Prädiktoren eines depressiven Rückfalls. Schlussfolgerung: Remittiert Depressive und Frührückfällige zeigen einen eingeschränkten Zugang zu PAG. Die schwache Produktion von PAG stellt einen Risikofaktor für einen depressiven Rückfall dar.
Physical and geometrical parameters of VCBS XIII: HIP 105947

The best physical and geometrical parameters of the main sequence close visual binary system (CVBS), HIP 105947, are presented. These parameters have been constructed conclusively using Al-Wardat’s complex method for analyzing CVBSs, which is a method for constructing a synthetic spectral energy distribution (SED) for the entire binary system using individual SEDs for each component star. The model atmospheres are in its turn built using the Kurucz (ATLAS9) line-blanketed plane-parallel models. At the same time, the orbital parameters for the system are calculated using Tokovinin’s dynamical method for constructing the best orbits of an interferometric binary system. Moreover, the mass-sum of the components, as well as the Δθ and Δρ residuals for the system, is introduced. The combination of Al-Wardat’s and Tokovinin’s methods yields the best estimations of the physical and geometrical parameters. The positions of the components in the system on the evolutionary tracks and isochrones are plotted and the formation and evolution of the system are discussed.
Alloyed CdTe 0.6 S 0.4 Quantum Dots Sensitized TiO 2 Electrodes for Photovoltaic Applications

The photovoltaic performance of alloyed CdTe0.6S0. 4 quantum dot sensitized solar cells (QDSSCs) is investigated. Fluorine doped Tin Oxide (FTO) substrates were coated with 20 nm-diameter TiO2 nanoparticles (NPs). Presynthesized colloidal solution of alloyed CdTe0.6S0. 4 quantum dots (QDs) of 4.2 nm was deposited onto TiO2 NPs substrates using direct adsorption (DA) technique, by dipping for different times at ambient conditions. The FTO counter electrodes were coated with platinum, while the electrolyte containing I-/I-3 redox species was sandwiched between the two electrodes. Compared to pure CdTe QDs and CdS QDs, CdTe0.6S0. 4 QDs showed better photovoltaic performance. The J-V characteristic curves of the assembled QDSSCs were measured at AM 1.5 simulated sunlight. The short current density (Jsc) and efficiency (η) increase with dipping time. At 24 h dipping time, the open-circuit photovoltage Voc, Jsc, fill factor (FF), and η were 0.46 volts, 1.54 mA/cm2, 0.43% and 0.31%, respectively.
An application of Macaulay’s estimate to sums of squares problems in several complex variables

Several questions in complex analysis lead naturally to the study of bihomogeneous polynomials r(z, z) on Cn×Cn for which r(z, z) ‖z‖ = ‖h(z)‖ for some natural number d and a holomorphic polynomial mapping h = (h1, . . . , hK) from Cn to CK . When r has this property for some d, one seeks relationships between d, K, and the signature and rank of the coefficient matrix of r. In this paper, we reformulate this basic question as a question about the growth of the Hilbert function of a homogeneous ideal in C[z1, . , zn] and apply a well-known result of Macaulay to estimate some natural quantities.
NYLON 6/CHITOSAN NANOFIBROUS STRUCTURES FOR FILTRATION

This research is to investigate nanoporous electrospun structures obtained from electrospinning technique for using as filters. In the research, Nylon 6 and the blend of Nylon 6/chitosan nanostructures were fabricated from polymer solutions at various concentrations ranging from 30 to 35% w/v. The kinematic viscosity of the Nylon 6 and Nylon 6/Chitosan solutions was determined by using Cannon-Fenske (Reverse Flow) viscometer while the morphology of nanofibers was observed with Scanning Electron Microscope (SEM). The results showed that the solutions with a higher viscosity yielded fibers with larger diameters and pores. Although the solution of nylon 6/chitosan at a ratio of 50:1 (30% wt nylon) had the highest viscosity in the experiment, the formation of small sized ultrafine fiber group generated even much smaller pores. In the filtration test, the flow rate of the suspension of polystyrene particles in water was adjusted to 8 µm/s and the nanofibrous filters with the thickness in the range of 0.1±0.02 mm were used. The results showed complete removals of polystyrene particles when using nanofibrous filters for both pure Nylon 6 and Nylon 6/chitosan nanofibers, being compared with the filter paper and commercial nylon fabric with No. 80/55 and No. 150/35, which showed much lower performance, i.e. filtration efficiency of 2.71 to 14.50%.
Therapeutic Efficacy of Quinapyramine Sulphate with Freund ’ s Complete Adjuvant in Wistar Rats Infected with Trypanosoma

Therapeutic efficacy of QS (quinapyramine sulphate) and FCA (Freund’s complete adjuvant) combination was studied. The aim of the study was to evaluate therapeutic efficacy of QS using FCA in Trypanosoma congolense infection. Groups treated with QS and FCA had parasite disappeared in peripheral circulation 2 days pi, relapse was observed one week later. Effect of treatment on rectal temperature shows no significance (p < 0.05), normalization of rectal temperature occurred in QS and FCA treated groups (34.1C) than untreated (42.8 C), QS (37.4 C) and FCA (35.92 C) treated groups. Mean body weight was significant (p < 0.001) in QS and FCA, QS, and FCA groups. Packed cell volume and hemoglobin concentration for untreated groups were lower, but increased in QS, FCA, QS and FCA treated groups, indicating anemia amelioration. White blood cell counted in untreated, QS and FCA treated groups showed no significance (p < 0.05), however, there was leukocytosis due to lymphocytosis in QS and FCA treated group (6.79 × 10/μl) compared with untreated and other groups. There was comparative decrease in serum liver enzymes in QS and FCA treated group than other groups. Therefore, QS at lower recommended dose with FCA may enhance efficacy of QS in trypanosomiasis.
A MODEL OF TROPICAL MARINE RESERVE‐FISHERY LINKAGES

ABSTRACT. The excessive and unsustainable exploitation of our marine resources has led to the promotion of marine reserves as a fisheries management tool. Marine reserves, areas in which fishing is restricted or prohibited, can offer opportunities for the recovery of exploited stock and fishery enhancement. In this paper we examine the contribution of fully protected tropical marine reserves to fishery enhancement by modeling marine reserve‐fishery linkages. The consequences of reserve establishment on the long‐run equilibrium fish biomass and fishery catch levels are evaluated. In contrast to earlier models this study highlights the roles of both adult (and juvenile) fish migration and larval dispersal between the reserve and fishing grounds by employing a spawner‐recruit model. Uniform larval dispersal, uniform larval retention and complete larval retention combined with zero, moderate and high fish migration scenarios are analyzed in turn. The numerical simulations are based on Mombasa Marine National Park, Kenya, a fully protected coral reef marine reserve comprising approximately 30% of former fishing grounds. Simulation results suggest that the establishment of a fully protected marine reserve will always lead to an increase in total fish biomass. If the fishery is moderately to heavily exploited, total fishery catch will be greater with the reserve in all scenarios of fish and larval movement. If the fishery faces low levels of exploitation, catches can be optimized without a reserve but with controlled fishing effort. With high fish migration from the reserve, catches are optimized with the reserve. The optimal area of the marine reserve depends on the exploitation rate in the neighboring fishing grounds. For example, if exploitation is maintained at 40%, the ‘optimal’ reserve size would be 10%. If the rate increases to 50%, then the reserve needs to be 30% of the management area in order to maximize catches. However, even in lower exploitation fisheries (below 40%), a small reserve (up to 20%) provides significantly higher gains in fish biomass than losses in catch. Marine reserves are a valuable fisheries management tool. To achieve maximum fishery benefits they should be complemented by fishing effort controls.
Construct by Contract: Construct by Contract: An Approach forDeveloping Reliable Software

This research introduces “Construct by Contract” as a proposal for a general methodology to develop dependable software systems. It describes an ideal process to construct systems by propagating requirements as contracts from the client’s desires to the correctness proof in verification stage, especially in everyday-used software like web applications, mobile applications and desktop application. Such methodology can be converted in a single integrated workspace as standalone tool to develop software. To achieve the already mentioned goal, this methodology puts together a collection of software engineering tools and techniques used throughout the software’s lifecycle, from requirements gathering to the testing phase, in order to ensure a contract-based flow. Construct by Contract is inclusive, regarding the roles of the people involved in the software construction process, including for instance customers, users, project managers, designers, developers and testers, all of them interacting in one common software development environment, sharing information in an understandable presentation according to each stage. It is worth to mention that we focus on the verification phase, as the key to achieve the reliability sought. Although at this point, we only completed the definition and the specification of this methodology, we evaluate the implementation by analysing, measuring and comparing different existing tools that could fit at any of the stages of software’s lifecycle, and that could be applied into a piece of commercial software. These insights are provided in a proof of concept case study, involving a productive Java Web application using struts framework.
Rhenium-188 Radiochemistry: Challenges and Prospects

After a lull in development of new chemistry for rhenium-188 and technetium-99m since 2000, there has been new investment in production facilities for Mo-99/Tc-99m coupled with increasing interest in rhenium-188 radionuclide therapy, particularly in developing countries. Much of the chemistry developed in the 1990s is not readily amenable to supporting modern radiopharmaceutical development, which places increased emphasis on molecular targeted radiopharmaceuticals. Consequently there is a need for new radiolabelling chemistry to incorporate these radionuclides into biomolecules using simple, kit-based methodology. This review provides an update on progress towards simple rhenium-188 labelling methods since 2000.
Multi-objective optimization of distributed generation with voltage step constraint

This paper presents the multi-objective optimization for high penetration of different type of distributed generations (DGs) considering voltage step constraint. In most of the studies in literature, the commonly used constraints are bus voltage limits and line power capacity limit. In this paper, it is analyzed that voltage step constraint affects the location, size and power factor of DG in distribution network. The studies are carried out for 17-bus, 38-bus and 76-bus distribution systems. Keywords: Distributed generation, distribution system, distributed generation planning, genetic algorithm
Optimized Design of Energy-Efficient IP Over WDM Networks

A surge of interest toward design and implementation of green networks are emerging in recent years. One obvious trend to reduce energy consumption of major active network components is to craft backbone network architecture that takes into consideration traffic grooming of low-rate IP traffic as well as power-aware virtual topology design schemes and RWA. Previous research efforts developed design strategies which assumed digital processing of incoming traffic flows at ever node structure in the optical layer (DXCs). This architecture provides full wavelength conversion capability by the use of optical transponders (OEO convertors) thus reduces complicated RWA problem to a simple routing problem at the cost of sacrificing lightpath transparency. Moreover, introduction of transponders give rise to extra sources of power consumption which contrasts over goal. In this paper, energy-minimized design of IP over WDM networks based on optical cross connects (OXCs) is investigated. Integer linear programming formulation for two design strategies viz. multi-hop lightpath and direct lightpath have been developed and their performance with regard to power consumption and bandwidth utilization are compared with prior studies. Simulation results indicate superior performance of the proposed multi-hop transparent lightpath strategy.
Combining mitochondrial DNA sequences and morphological data to infer species boundaries: phylogeography of lanceheaded pitvipers in the Brazilian Atlantic forest, and the status of Bothrops pradoi (Squamata: Serpentes: Viperidae)

Phylogeographic studies using mitochondrial DNA sequence information are frequently used as the principal source of evidence to infer species boundaries. However, a critical analysis of further evidence is essential to test whether different haplotype clades identify different species. We demonstrate a hypothesis‐testing approach, using a combination of phylogeographic methods, multivariate morphometrics and matrix association tests, to investigate species boundaries in eastern Brazilian pitvipers conventionally assigned to the species Bothrops leucurus and B. pradoi. Two basal haplotype clades with partly overlapping geographical distributions are identified, which could either represent two partly sympatric species, or multiple haplotypes within one organismal lineage. We use partial Mantel matrix association tests to verify whether generalized morphology, or any of four supposedly diagnostic characters for the two species, show any association with mtDNA variation. Negative results lead to the conclusion that the haplotype clades do not denote independently evolving organismal lineages, and do not constitute separate species under any criterion.
Lifestyle and Health Risk Behaviours among Elbasan Students

Abstract AIM: The purpose of this study is: (1) to help monitor the Albanian students’ lifestyle, the way they spend their free time, the weight that studying, networks, screens and sports have in their life; (2) to assess their health risk behaviours, such as tobacco and drug use, weapon carrying and sports betting; (3) to identify differences in behaviour by gender, grade, socioeconomic and demographic status; (4) to understand the influence of parents on their children. METHOD: The study was conducted in May 2013, as a classroom survey of students in urban and rural schools of Elbasan. A questionnaire was distributed to the 8th to 12th grade students to be completed by them anonymously. RESULT: There are a low number of the students that are interested to books and study and meantime, a large number of them spend their free time in front of a screen or hanging out in bars with friends. Moreover, a considerable number of them are engaged in health risk behaviours. CONCLUSION: In students’ lifestyle exist serious problems and these data also provide inside into ways to shape a public health response. We need to change the way society views and treats these problems.
Competitive urbanism and the limits to smart city innovation: The UK Future Cities initiative

The technological vision of smart urbanism has been promoted as a silver bullet for urban problems and a major market opportunity. The search is on for firms and governments to find effective and transferable demonstrations of advanced urban technology. This paper examines initiatives by the UK national government to facilitate urban technological innovation through a range of strategies, particularly the TSB Future Cities Demonstrator Competition. This case study is used to explore opportunities and tensions in the practical realisation of the smart city imaginary. Tensions are shown to be partly about the conjectural nature of the smart city debate. Attention is also drawn to weakened capacity of urban governments to control their infrastructural destiny and also constraints on the ability of the public and private sectors to innovate. The paper contributes to smart city debates by providing further evidence of the difficulties in substantiating the smart city imaginary.
The Assessment of Present, Past and Future Climate Variability in the Americas from Treeline Environments

In this note we introduce one of 14 Collaborative Research Networks (CRN) funded by the Inter-American Institute for Global Change Research. It was established in 1999 and involves 15 principal investigators from 13 institutions in Canada, USA, Mexico, Bolivia, Chile and Argentina. The primary goals of the project are (i) to develop a network of tree-ring chronologies from climatically-sensitive treeline sites in the western American Cordillera and (ii) to use these data to reconstruct and compare regional interannual to decadal climate variability along the PEP-1 transect from Alaska to Tierra del Fuego. The project also seeks to enhance the development and utilization of dendrochronology for tropical mountain tree species and expand collaboration, training and the application of paleoenvironmental science within Latin America to address the issues of climate variability and change.
Effects of manual therapy in the treatment of temporomandibular dysfunction - a review of the literature

Background: The term temporomandibular dysfunction (TMD) applies to functional changes related to temporomandibular joint (TMJ) and it is associated to masticatory structures. The main symptoms are pain in the TMJ region and / or the masticatory musculature. Objective: to perform a systematic review on the effects of manual therapy in the treatment of TMD. Methods: We analyzed 231 articles from the databases of Bireme, BVS, Lilacs, MedLine, PEDro, Pubmed and, Scielo. Of these, only 30 were selected for the elaboration of the article and 6 were used for the qualitative synthesis. Studies of controlled clinical trials of high methodological quality and high clinical relevance on the PEDro scale were included, which used the same evaluation measures, VAS (visual analogic scale), PPT (pressure pain threshold) and maximum mouth opening (MMO), and only one treatment technique comparing the control group with placebo. Result: The studies presented positive results for pain in VAS, PPT and MMO; however, there are significant differences depending on the technique. Myofascial release has a strong efficacy in reducing the symptoms of acute pain in the long term, but does not show clinically significant changes in mouth opening amplitude and MMO. Mobilization / manipulation presents significant changes in MMO, significantly improving the efficacy of mouth range of motion in the treatment of the short-term pain symptom, however does not sustain in the long term. Conclusion: The tool for the individual treatment of patients is based on the symptoms addressed, significantly improving the effectiveness of the range of motion of the mouth in the treatment of joint mobilization / manipulation, and treatment of pain by myofascial release.
Effect of Fertilizer Additions on Plant Communities and Soil Properties in a Temperate Grassland Steppe

Temperate grassland steppe is an important natural ecosystem in the world, which is being degraded under the combined pressure of climate change and human over-utilization. Our objective was to determine the effect of inorganic and organic fertilizer addition and determine the appropriate fertilizer resource and additional rate for temperate grassland restoration. The treatments consisted of an inorganic and organic fertilizer, each with three additional rates. The effect of fertilizer addition on aboveground biomass, community structure, soil properties, and N balance were examined using a 2-year in situ controlled trial at Guyuan Grassland Station, Hebei Province, China. The results showed that inorganic fertilizer treatments increased the aboveground biomass, and decreased diversity and evenness of the plant community. Organic fertilizer treatments increased soil total carbon and the carbon-to-nitrogen ratio, but did not significantly change the aboveground biomass and soil available nutrition during the 2-year experiment. The N quantity of plant harvest output is approximate to that of fertilizer addition input in inorganic fertilizer treatment with 75 kg hm-2 urea and 45 kg hm-2 diammonium phosphate. The study demonstrated that using fertilizer addition to restore temperature grassland steppe requires a comprehensive evaluation of the diverse services functions of the present and
On the detection of self-similarities in vibro-acoustic signals

In this paper, a novel idea of organizing the search for similar fragments in vibro-acoustic signals (and not only) is proposed. The key point of this proposal is the task-oriented use of the signal smoothness parameter values (smoothness estimates). Firstly, the notion of smoothness of the signal is introduced; secondly, an iterative procedure for finding the signal smoothness estimates is presented; finally, some important properties of the signal smoothness estimates are formulated and proved. A special attention is paid to the necessary signal similarity condition; it is proved that small fragmentary changes in the vibro-acoustic signal lead to small changes in the signal smoothness parameter value. Preliminary experimental analysis results showed that the use of the necessary signal similarity condition might be of service in gear fault diagnosis, in fractal forecasting of real acoustical time series, in speeding-up some computational processes associated with interpolation of vibro-acoustic signals, data mining, etc.
