Relationship between Problematic Internet Use, Depression and Quality of Life Levels of Turkish University Students

The relationship between problematic Internet use (PIU), depression and quality of life levels of individuals is a growing concern in many societies. One of the main purposes of this study was to examine the relationships or correlations among PIU, depression and quality of life levels of Turkish undergraduate students. Furthermore, this study sought to investigate whether correlated variables; if any, simultaneously predicted students’ quality of life levels on different domains of WHOQOL–BREF-TR in a significant manner. Moreover, this research examined whether some or any of study variables had a mediating effect in relationships between domains of WHOQOL–BREF-TR and other study variables. The data collected from 758 undergraduate student participants (431 female and 327 male) attending different faculties and colleges at a public university in Turkey. A demographical information form, the Beck Depression Inventory, the World Health Organization’s Quality of Life-BREF (WHOQOL–BREF-TR) and Online Cognition Scale (OCS) were used to collect data from the undergraduate Turkish students. The results indicated that the students’ PIU and depression levels were negatively associated with quality of life levels and positively associated with each other in a significant manner. Moreover, the results of hierarchical regression analysis revealed that PIU levels of the students on the diminished impulse control dimension partially mediated the relationships between depression and quality of life levels on all domains of WHOQOL–BREF-TR.
Development of a Benchmark Example for Delamination Fatigue Growth Prediction

The development of a benchmark example for cyclic delamination growth prediction is presented and demonstrated for a commercial code. The example is based on a finite element model of a Double Cantilever Beam (DCB) specimen, which is independent of the analysis software used and allows the assessment of the delamination growth prediction capabilities in commercial finite element codes. First, the benchmark result was created for the specimen. Second, starting from an initially straight front, the delamination was allowed to grow under cyclic loading in a finite element model of a commercial code. The number of cycles to delamination onset and the number of cycles during stable delamination growth for each growth increment were obtained from the analysis. In general, good agreement between the results obtained from the growth analysis and the benchmark results could be achieved by selecting the appropriate input parameters. Overall, the results are encouraging but further assessment for mixed-mode delamination is required.
1 Gene and protein expression in myometrium in pregnancy and labor 1 2 3 4 5 6 7

10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Microarray technologies widen our comprehension of the major structural and metabolic transformations which affect the myometrium from the very beginning of pregnancy until parturition. The results are coherent with the mass of information which was accumulated previously, primarily on the basis of studies of selected critical factors. They highlight the activation of precise signaling pathways, some of which may have been previously under evaluated. The remodelling and maturation processes that the myometrium undergoes in pregnancy appear clearly as phenomenon's which last during the full course of gestation. Comparatively, the onset of labor is perhaps the phenomenon which remains the least well described by these methods of analysis. Nevertheless, genomic studies constitute a necessary first step of orientation and help establishing new links between the generic signaling pathways that are activated during the normal or pathological gestation. These studies also represent an indicative step that will have to be paralleled, in the future, with the results of the systematic proteomic analysis of the myometrium.

Expanding The Genetic Code iGEM Bielefeld-CeBiTec 2017

Fusing We designed and synthesized a novel ncAA called CBT-asparagine. It enables a highly specific covalent fusing reaction to another ncAA, cysteinyl-lysine. We confirmed the fusion in vitro via MS and successfully modeled several aaRS sequences for the translational incorporation of CBT-asparagine into proteins. Protein design is usually limited to 20 amino acids. Since the chemical abilities of these amino acids are limited, a lot of interesting functions are not applicable in protein design. We aim to enable the translational incorporation of non-canonical amino acids (ncAAs) through an expanded genetic code.
Efficient Exhaustive Search of Power-Split Hybrid Powertrains With Multiple Planetary Gears and Clutches

Planetary gear (PG) power-split hybrid powertrains have been used in producing hybrid and plug-in hybrid vehicles from the Toyota, General Motor, and Ford for years. Some of the most recent designs use clutches to enable multiple operating modes to improve launching performance and/or fuel economy. Adding clutches and multiple operating modes, however, also increases production cost and design complexity. To enable an exhaustive but fast search for optimal designs among a large number of hardware configurations, clutch locations, and mode selections, an automated modeling and screening process is developed in this paper. Combining this process with the power-weighted efficiency analysis for rapid sizing method (PEARS), an optimal and computationally efficient energy management strategy, the extremely large design space of configuration, component sizing, and control becomes feasible to search through. This methodology to identify optimal designs has yet to be reported in the literature. A case study to evaluate the proposed methodology uses the configuration adopted in the Toyota Hybrid Synergy (THS-II) system used in the Prius model year 2010 and the Hybrid Camry. Two designs are investigated to compare with the simulated Prius design: one uses all possible operating modes; and the other uses a suboptimal design that limits the number of clutches to three.

A glitch in the millisecond pulsar J0613-0200

We present evidence for a small glitch in the spin evolution of the millisecond pulsar J0613−0200, using the EPTA Data Release 1.0, combined with Jodrell Bank analogue filterbank TOAs recorded with the Lovell telescope and Effelsberg Pulsar Observing System TOAs. A spin frequency step of 0.82(3) nHz and frequency derivative step of −1.6(39) × 10 −19 Hz s −1 are measured at the epoch of MJD 50888(30). After PSR B1821−24A, this is only the second glitch ever observed in a millisecond pulsar, with a fractional size in frequency of Δν/ν = 2.5(1) × 10 −12 , which is several times smaller than the previous smallest glitch. PSR J0613−0200 is used in gravitational wave searches with pulsar timing arrays, and is to date only the second such pulsar to have experienced a glitch in a combined 886 pulsar-years of observations. We find that accurately modelling the glitch does not impact the timing precision for pulsar timing array applications. We estimate that for the current set of millisecond pulsars included in the International Pulsar Timing Array, there is a probability of ∼ 50% that another glitch will be observed in a timing array pulsar within 10 years.
The Apoe -/- Mouse PhysioLab ® Platform: A Validated Physiologically-based Mathematical Model of Atherosclerotic Plaque Progression in the Apoe -/- Mouse

Motivation: Atherosclerosis is a complex multi-pathway inflammatory disease where accumulation of oxidatively modified lipids and leukocytes in the arterial intima leads to plaque formation over time. Translating Apoe -/- mouse results to the clinical setting is complicated by uncertainty around (a) mechanisms underlying disease etiology, (b) relative importance of these mechanisms as drivers of progression, and (c) how these roles change in response to perturbation by therapeutic intervention or lifestyle changes. Results: We describe a large-scale mechanistic, mathematical model of atherosclerosis in the Apoe -/- mouse and its validation with in vivo Apoe -/- data. Major physiological components include cholesterol/macrophage trafficking, inflammation, endothelial function, oxidative stress, and thrombosis. Heterogeneity in disease progression, observed despite genetic uniformity and experimentally controlled conditions, was captured through “virtual mice”. This model may be used to optimize in vivo experiments and paves the way for a similar modeling approach for human disease. Availability: The model is available by remote desktop client at Apoe.entelos. com.
Chapter 2 Massive Graph Management for the Web and Web 2 . 0

The problem of efficiently managing massive datasets has gained increasing attention due to the availability of a plethora of data from various sources, such as the Web. Moreover, Web 2.0 applications seem to be one of the most fruitful sources of information as they have attracted the interest of a large number of users that are eager to contribute to the creation of new data, available online. Several Web 2.0 applications incorporate Social Tagging features, allowing users to upload and tag sets of online resources. This activity produces massive amounts of data on a daily basis, which can be represented by a tripartite graph structure that connects users, resources and tags. The analysis of Social Tagging Systems (STS) emerges as a promising research field, enabling the identification of common patterns in the behavior of users, or the identification of communities of semantically related tags and resources, and much more. The massive size of STS datasets dictates the necessity for a robust underlying infrastructure to be used for their storage and access. This chapter contains a survey of existing solutions to the problem of storing and managing massive graph data focusing particularly on the implications that the underlying technologies of such frameworks have on the support/operation of Web 2.0 applications using them as back-end storage solutions, as well as on the efficient execution of web mining tasks. Considering the category of STS as an example of Web 2.0 applications, the requirements that are posed for the management of STS data are thoroughly discussed. On the basis of these requirements three frameworks have been developed, using state-of-the-art technologies as backbones. The results of benchmarks conducted on the developed frameworks are presented and discussed.
Composite model reference adaptive control for an unmanned underwater vehicle

The control of unmanned underwater vehicles (UUVs) is challenging due to the non-linear and time-varying nature of the hydrodynamic forces from the surrounding fluid. In addition, the presence of external disturbances makes the control even more difficult. Model reference adaptive control (MRAC) is an adaptive control technique that performs well in such situations, while the improved composite/combined model reference adaptive control (CMRAC) is capable of better transient performance. However, the latter is yet to be used in UUV controls. Thus, this paper tests the suitability of CMRAC in UUV applications using validated simulation models and compares its performance against the standard MRAC. Several test scenarios have been considered including initial operation, external disturbance and thruster failure. Simulation results show that CMRAC offers better tracking, faster disturbance rejection and quick recovery from thruster failure compared to MRAC. In addition, CMRAC is more robust against parameter uncertainties and thus the control signal shows fewer oscillations, which in turn reduces the probability of actuator damage.

Localization of zearalenone detoxification gene(s) in pZEA-1 plasmid of Pseudomonas putida sp. strain ZEA-1 and expressed inEscherichia coli.

The gene(s) encoding enzyme(s) involved in the initial reaction during degradation of zearalenone was characterized from the zearalenone utilizer Pseudomonas putida strain ZEA-1, in which ZEA transformed into product with less or not toxic. A 5.5 kilobase-pair (kpb) Pst1-Kpn1 fragment containing gene(s) coding for zearalenone degradation was cloned. The cloned gene(s) activity was expressed in Escherichia coli, and ZEA degradation by recombinant E. coli was relatively rapid and effective, leaving no detectable ZEA after 72 h. In further experiments, cell-free extract of E.coli have been used in the same way, both to confirm these observations and the enzymatic nature of the degradation activity.
The unusual protoplanetary disk around the T Tauri star ET Chamaeleontis

We present new continuum and line observations, along with modelling, of the faint (6-8) Myr old T Tauri star ET Cha belonging to the eta Chamaeleontis cluster. We have acquired Herschel/PACS photometric fluxes at 70 mu m and 160 mu m, as well as a detection of the [OI] 63 mu m fine-structure line in emission, and derived upper limits for some other far-IR OI, CII, CO and o-H2O lines. These observations were carried out in the frame of the open time key programme GASPS, where ETCha was selected as one of the science demonstration phase targets. The Herschel data is complemented by new simultaneous ANDICAM B-K photometry, new HST/COS and HST/STIS UV-observations, a non-detection of CO J = 3 -> 2 with APEX, re-analysis of a UCLES high-resolution optical spectrum showing forbidden emission lines like [OI] 6300 angstrom, [SII] 6731 angstrom and 6716 angstrom, and [NII] 6583 angstrom, and a compilation of existing broad-band photometric data. We used the thermo-chemical disk code ProDiMo and the Monte-Carlo radiative transfer code MCFOST to model the protoplanetary disk around ETCha. The paper also introduces a number of physical improvements to the ProDiMo disk modelling code concerning the treatment of PAH ionisation balance and heating, the heating by exothermic chemical reactions, and several non-thermal pumping mechanisms for selected gas emission lines. By applying an evolutionary strategy to minimise the deviations between model predictions and observations, we find a variety of united gas and dust models that simultaneously fit all observed line and continuum fluxes about equally well. Based on these models we can determine the disk dust mass with confidence, M-dust approximate to (2-5) x 10(-8) M-circle dot whereas the total disk gas mass is found to be only little constrained, M-gas approximate to (5 x 10(-5)-3 x 10(-3)) M-circle dot. Both mass estimates are substantially lower than previously reported. In the models, the disk extends from 0.022 AU (just outside of the co-rotation radius) to only about 10 AU, remarkably small for single stars, whereas larger disks are found to be inconsistent with the CO J = 3 -> 2 non-detection. The low velocity component of the [OI] 6300 angstrom emission line is centred on the stellar systematic velocity, and is consistent with being emitted from the inner disk. The model is also consistent with the line flux of H-2 v = 1 -> 0 S(1) at 2.122 mu m and with the [OI] 63 mu m line as seen with Herschel/PACS. An additional high-velocity component of the [OI] 6300 angstrom emission line, however, points to the existence of an additional jet/outflow of low velocity 40-65 km s(-1) with mass loss rate approximate to 10(-9) M-circle dot/yr. In relation to our low estimations of the disk mass, such a mass loss rate suggests a disk lifetime of only similar to 0.05-3 Myr, substantially shorter than the cluster age. If a generic gas/dust ratio of 100 was assumed, the disk lifetime would be even shorter, only similar to 3000 yrs. The evolutionary state of this unusual protoplanetary disk is discussed.
Determinants of Market Participation by Indigenous Poultry Farmers: A Case Study in Anuradhapura District in Sri Lanka

Backyard poultry farming provides multiple benefits to rural farm families in Sri Lanka. Indigenous chicken or the village chicken is the main component in backyard poultry rearing system. However, the indigenous chicken population is gradually being reduced in the country, mainly with the introduction of exotic breeds. In addition, market share of indigenous chicken is diminishing over the years. Identification of the characteristics of the farmers selling indigenous chicken and the factors that affect the market participation by indigenous chicken farmers will be useful in conservation and sustainable utilization of indigenous chicken. Hence, the objectives of this study were to identify the factors that determine poultry market participation and sales of indigenous chicken farmers. Those determinants were evaluated by using Heckman two stage econometric model. The study was carried out in Thirappane Veterinary Division (covering four selected villages) in Anuradhapura district. Data were collected by a household survey using a structured questionnaire from 104 households rearing indigenous chicken. The first step of the Heckman two stage procedure results showed that households’ decision to participate in the poultry market was significantly (p Tropical Agricultural Research Vol. 24 (4): 347-361 (2013)
Marsupial development in the mysid Neomysis integer ( Crustacea : Mysidacea ) to evaluate the effects of endocrine-disrupting chemicals

Embryonic development is a crucial time window within an organism’s life history. Relatively few studies have focused on understanding the potential effects of endocrine disruptors on embryogenesis in invertebrates. Mysids (Crustacea: Mysidacea) have been used extensively in regulatory toxicity testing and they are the only invertebrate model currently included in the U.S. EPA’s Endocrine Disruptor Screening and Testing Program. We developed a method for studying mysid embryonic development in multiwell plates until the release of free-swimming juveniles. This method was used to evaluate the potential effects of the insecticide methoprene, a juvenile hormone analog, on mysid embryogenesis. Embryos were exposed to nominal concentrations 0.01, 1, and 100mg methoprene/L. Average percentage survival, hatching success, total development time and duration of each developmental stage were analyzed. Embryos exposed to 1 and 100mg methoprene/L had a significantly lower hatching success and lower survival rates. Our study indicates that in vitro embryogenesis can be used as a valuable tool to study the impact of endocrine disruptors in mysids. r 2006 Elsevier Inc. All rights reserved.
The Neotropical Ornithological Society PHYLOGENETIC RELATIONSHIPS AMONG HEMISPINGUS TANAGERS

– Phylogenetic relationships among Hemispingus tanagers are currently not well understood. Recent work based on partial mtDNA sequences of the ND2 gene supported unambiguously the monophyly of the genus. The genus Cnemoscopus has been considered sister to the genus Hemispingus. We added the corresponding ND2 sequences of H. parodii and Cnemoscopus rubrirostris to our previous data set, and reanalyzed it. We also analyzed partial cytochrome b sequences for a subset of species. Our best hypothesis suggests three main clades within the genus: 1) ochraceous birds (frontalis, melanotis, piurae, and trifasciatus), 2) conspicuous eye-browed birds (calophrys, parodii, auricularis, atropileus), and 3) warbler-like birds (xanthophthalmus and verticalis). The position of H. superciliaris (and presumably reyi) is ambiguous, with results placing it either with the ochraceous birds or with the warbler-like birds. The deepest Hemispingus, basal to these three clades, is H. rufosuperciliaris (and H. goeringi). Analyses of both mitochondrial gene fragments suggest Cnemoscopus rubrirostris is part of the Hemispingus assemblage, occupying a basal position in the phylogeny of the group. Additional analyses including Poospiza species, however, fail to recover a monophyletic Hemispingus. The current data available are thus insufficient to unambiguously confirm or reject monophyly of the genus. Accepted 30 November 2002.
Interpersonal sensorimotor contingencies: Information-theoretic relevance of subjective experience

Interpersonal synergies are higher-order control systems formed by coupling movement of two (or more) actors. Many different approaches have been utilised for the characterisation of social couplings, such as autocorrelation, crosscorrelation (Box and Jenkins (1970)), transfer entropy (Barnett et al. (2009)), Granger causality (Granger (1969)), and their potential has been demonstrated in many applications. Simultaneous hyper-scanning of several brains have recently opened a new field (Babiloni et al. (2006); Astolfi et al. (2010); Schippers et al. (2010); Anders et al. (2011); Dumas et al. (2010)). A key challenge is to design a suitable procedure that allows synchrony and turn-taking to spontaneously take place. Traditional interactive paradigms mainly consist of non-contingent social stimuli that do not allow true social interaction (Redcay et al. (2010)). Imitation is typically used in an interpersonal context with the aim to contribute identifying neurodynamic signatures of human interactions and detect, for example, different patterns of synchrony and movement abnormalities (Grossberg and Seidman (2006)), providing insights about autistic spectrum disorder. A neuromarker of social coordination (known as phi complex) was detected over the right centroparietal area in the 9.2-11.5 Hz range (Tognoli et al. (2007)). However, apparent interpersonal coordination could be merely incidental rather than reflecting true coordination – people may appear to coordinate their movements because they simultaneously execute similar motor programs, mediated by shared motor representations (Garrod and Pickering (2009); Sebanz et al. (2006)).
