description: Increase in N application rates may eventually raise the potential groundwater N-pollution. This survey study was conducted by Soil Chemistry Section, ISCES to assess the NO3 contents of soil from 0 to 120 cm depth with different intervals. For this purpose, the soil and water samples were collected from Okara, Vehari Sialkot, Chiniot, Hafizabad, Sahiwal and Multan districts. The results showed that nitrate leaching occurred but it is only up to 2 feet soil depth. The NO3-N contents were maximum at two upper depths (i.e. 0-30 cm and 30-60 cm) and then decreased gradually downward. The highest average NO3-N content was found at 0-30 cm soil depth and the lowest were found at 90-120 cm. The data also revealed that mean NO3-N content at 0-30, 30-60, 60-90 and 90-120 cm depths were 16.85±4.05, 15.21±4.77, 9.94±3.36 and 6.54±2.62 mg kg-1, respectively, whereas NO3-N content at same depths were ranged from 11.50-26.20, 6.53-21.15, 5.24-16.12, 1.45-9.36 mg kg-1, respectively. The results regarding underground water samples (tube well) from the same sites from all the three districts showed that NO3 were found in all the water samples but it was only in traces and their concentration were not much higher to create the health hazardous problem owing to NO3 leaching. The data showed that the highest NO3 contents did not exceed than 8.61 and 10.6 ppm in Multan and Sahiwal districts respectively, which were much lower than permissible limit i.e. 50 ppm (FAO). Similarly, the nitrate content in underground water are well below the maximum admissible limit of WHO i.e. 50 mg L-1.

description: The investigation was executed to assess outflows of CO2 and CH4 gases from the two landfill sites of Udaipur using commonly applied multiple methodologies for the field to ascertain the accuracy and reliability of data imparted by each of these. To examine the potentiality of each gas discharge quantum for prospective energy that could be used further in waste-to-energy (WtE) projects, a field study was conducted for a period from January 2018 to December 2019 with the division of these landfill sites into segments. The gas samples were recorded onsite at demarked points in each segment by inverting the open portion of the Static Flux Chambers (SFCs) on the landfill surface to stop the ingress of air. This SFC was separately connected with the CO2 and CH4 gas analysers to record their onsite concentrations. The recorded data was further analysed to observe the annual quantitative spatial and temporal variations in the fluxes of these two gases. The mean CO2 and CH4 fluxes of Balicha Landfill Site (BLS) ranged between 932-1876μg/m2/hr and 359-1173μg/m2/hr, respectively. On the other hand the mean CH4 and CO2 fluxes of Titardi Landfill Site (TLS) ranged between 672 - 1483 μg/m2/hr and 157 - 958 μg/m2/hr, respectively. These fluxes emitted from BLS and TLS generated the carbon footprint (CF) of 180000 and 78000 ton of CO2 equivalent (tCO2 eq.) sequentially. In order to ensure the significance of the method used and to get best energy output for the WtE project the obtained gas flux data of both the sites was analysed and compared. This studied data would provide a guideline for the concerned authorities to plan & execute gas extraction operations at these two sites.

description: Abstract Background This study investigated the relationship between changes in lung function (as measured by forced expiratory volume in one second [FEV1]) and the St. George’s Respiratory Questionnaire (SGRQ) and economically significant outcomes of exacerbations and health resource utilization, with an aim to provide insight into whether the effects of COPD treatment on lung function and health status relate to a reduced risk for exacerbations. Methods A systematic literature review was conducted in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify randomized controlled trials of adult COPD patients published in English since 2002 in order to relate mean change in FEV1 and SGRQ total score to exacerbations and hospitalizations. These predictor/outcome pairs were analyzed using sample-size weighted regression analyses, which estimated a regression slope relating the two treatment effects, as well as a confidence interval and a test of statistical significance. Results Sixty-seven trials were included in the analysis. Significant relationships were seen between: FEV1 and any exacerbation (time to first exacerbation or patients with at least one exacerbation, p = 0.001); between FEV1 and moderate-to-severe exacerbations (time to first exacerbation, patients with at least one exacerbation, or annualized rate, p = 0.045); between SGRQ score and any exacerbation (time to first exacerbation or patients with at least one exacerbation, p = 0.0002) and between SGRQ score and moderate-to-severe exacerbations (time to first exacerbation or patients with at least one exacerbation, p = 0.0279; annualized rate, p = 0.0024). Relationships between FEV1 or SGRQ score and annualized exacerbation rate for any exacerbation or hospitalized exacerbations were not significant. Conclusions The regression analysis demonstrated a significant association between improvements in FEV1 and SGRQ score and lower risk for COPD exacerbations. Even in cases of non-significant relationships, results were in the expected direction with few exceptions. The results of this analysis offer health care providers and payers a broader picture of the relationship between exacerbations and mean change in FEV1 as well as SGRQ score, and will help inform clinical and formulary-making decisions while stimulating new research questions for future prospective studies.

description: Hawking radiation has been regarded as a more general phenomenon than in gravitational physics, in particular in laboratory analogs of the event horizon. Here we consider the fiber-optical analog of the event horizon, where intense light pulses in fibers establish horizons for probe light. Then, we calculate the Hawking spectrum in an experimentally realizable system. We found that the Hawking radiation is peaked around group-velocity horizons in which the speed of the pulse matches the group velocity of the probe light. The radiation nearly vanishes at the phase horizon where the speed of the pulse matches the phase velocity of light.

description: Abstract Background The variation in serum uric acid concentrations is under significant genetic influence. Elevated SUA concentrations have been linked to increased risk for gout, kidney stones, chronic kidney disease, and cardiovascular disease whereas reduced serum uric acid concentrations have been linked to multiple sclerosis, Parkinson’s disease and Alzheimer’s disease. Previously, we identified a novel locus on chromosome 3p26 affecting serum uric acid concentrations in Mexican Americans from San Antonio Family Heart Study. As a follow up, we examined genome-wide single nucleotide polymorphism data in an extended cohort of 1281 Mexican Americans from multigenerational families of the San Antonio Family Heart Study and the San Antonio Family Diabetes/Gallbladder Study. We used a linear regression-based joint linkage/association test under an additive model of allelic effect, while accounting for non-independence among family members via a kinship variance component. Results Univariate genetic analysis indicated serum uric acid concentrations to be significant heritable (h 2 = 0.50 ± 0.05, p < 4 × 10−35), and linkage analysis of serum uric acid concentrations confirmed our previous finding of a novel locus on 3p26 (LOD = 4.9, p < 1 × 10−5) in the extended sample. Additionally, we observed strong association of serum uric acid concentrations with variants in following candidate genes in the 3p26 region; inositol 1,4,5-trisphosphate receptor, type 1 (ITPR1), contactin 4 (CNTN4), decapping mRNA 1A (DCP1A); transglutaminase 4 (TGM4) and rho guanine nucleotide exchange factor (GEF) 26 (ARHGEF26) [p < 3 × 10−7; minor allele frequencies ranged between 0.003 and 0.42] and evidence of cis-regulation for ITPR1 transcripts. Conclusion Our results confirm the importance of the chromosome 3p26 locus and genetic variants in this region in the regulation of serum uric acid concentrations.

description: It is no more news that the deterioration of our mother Earth has resulted in many hardships faced in many lands of the world. Research statistics has shown that about 80% of the environmental problems faced in Asia, especially the loss of soil biodiversity results from deforestation. Africa has been intensely affected by the hazards of climate change at a rate of more than 50%, also Near East and North Africa has recorded more than 48% loss of her biodiversity in soils due to habitat alteration and loss. This list is inexhaustive and heart-broken, presenting a view that if sustainable remediation is not taken then we will have more malnourished and sick people in years to come, our environment will be more polluted and toxic, our water system will become more and more difficult to remediate, there could be increase in local, national and international conflict among other unforeseen unpleasant happenings. To contribute as a modality towards solving this problem this study investigated the current soil organic carbon-soil biodiversity variability in the ecosystem-nexus of soils. The study took place within the University of Abuja landmass. Spatial and temporal data were collected on earth-system properties, were analysis and simulations were done. The Area was model and interpolated to find hot spots with grave threat. Explorative and descriptive statistics was applied in the study. Results indicated that the soils of the study area are compacted and hence unfit to support sustainable survival of the living entities within the soil system, with soil Bulk density value range at 2.1g cm-3–2.71g cm-3. Organic carbon of the area was low. Geotechnical and geomorphological evaluation and interactions revealed only two (2) points having earthworm length of 1 cm which presented a view that the soils spore is too tight to enable sustainable flourishing of below and above ground biodiversity in the sites investigated. Hence ecological tool like the use of Vetiver Grass Technology was recommended for the study area environmental regeneration and for healing the soils impediment.

description: Active galactic nuclei (AGN) are the most luminous and abundant objects in the γ-ray sky. AGN with jets misaligned along the line-of-sight (MAGN) appear fainter than the brighter blazars, but are expected more numerous. Fermi Large Area Telescope (LAT) detected 40 MAGNs compared to 1943 blazars. The aim of this study is to identify new MAGN candidates in the blazars of uncertain type (BCUs) listed in the Fermi-LAT 10-year Source Catalog using an artificial neural network (ANN). The statistical tests applied to the trained ANN reveals that a classification with machine learning techniques is feasible with high accuracy and precision. The trained ANN has been applied to the 1120 BCUs which have been classified into 655 BL Lacs and 314 flat spectrum radio quasars (FSRQs). Among the re-classified BCUs, the possible MAGN candidates have been determined by applying thresholds on the spectral index, variability index and gamma-ray luminosity. Our results led to 36 possible MAGN candidates, which respect the main physical properties of the 40 MAGN already listed in the Fourth Fermi Catalog.

description: Estimating a signal embedded in noise requires taking advantage of any prior information about the signal and noise. Until recently, signal processing estimation was primarily Bayesian and linear. Non-linear smoothing algorithms existed in statistics, but these procedures were often ad-hoc and complex. Donoho and Johnstone proved that a simple thresholding algorithm on an appropriate basis could be a nearly optimal non-linear estimator. A radio signal induced from cosmic ray is very well described, for example, by the Daubechies wavelets as a basis, allowing the thresholding to be as safe (or more) as a linear estimation. The best basis search or a pursuit algorithm may also improve the thresholding performance as it adapts the basis to the noisy data. This work presents the wavelets as a denoising technique for narrowband and gaussian background reduction in radio signals induced from cosmic rays, showing its efficiency in energy reconstruction.

description: Abstract Background Decision aids can improve decision making processes, but the amount and type of information that they should attempt to communicate is controversial. We sought to compare, in a pilot randomized trial, two colorectal cancer (CRC) screening decision aids that differed in the number of screening options presented. Methods Adults ages 48–75 not currently up to date with screening were recruited from the community and randomized to view one of two versions of our previously tested CRC screening decision aid. The first version included five screening options: fecal occult blood test (FOBT), sigmoidoscopy, a combination of FOBT and sigmoidoscopy, colonoscopy, and barium enema. The second discussed only the two most frequently selected screening options, FOBT and colonoscopy. Main outcomes were differences in screening interest and test preferences between groups after decision aid viewing. Patient test preference was elicited first without any associated out-of-pocket costs (OPC), and then with the following costs: FOBT-$10, sigmoidoscopy-$50, barium enema-$50, and colonoscopy-$200. Results 62 adults participated: 25 viewed the 5-option decision aid, and 37 viewed the 2-option version. Mean age was 54 (range 48–72), 58% were women, 71% were White, 24% African-American; 58% had completed at least a 4-year college degree. Comparing participants that viewed the 5-option version with participants who viewed the 2-option version, there were no differences in screening interest after viewing (1.8 vs. 1.9, t-test p = 0.76). Those viewing the 2-option version were somewhat more likely to choose colonoscopy than those viewing the 5-option version when no out of pocket costs were assumed (68% vs. 46%, p = 0.11), but not when such costs were imposed (41% vs. 42%, p = 1.00). Conclusion The number of screening options available does not appear to have a large effect on interest in colorectal cancer screening. The effect of offering differing numbers of options may affect test choice when out-of-pocket costs are not considered.

This provides the second known example in this class besides the uplift of the Pernici and Sezgin solution to 7d gauged supergravity constructed in the eighties. We compute the free energy of the solution, and show that it scales as $N^{3/2}$. It is intriguing that even though the natural holographic interpretation is in terms of M5-branes wrapped on a special Lagrangian 3-cycle, this solution does not exhibit the expected $N^3$ behavior.

7TMRmine: a Web server for hierarchical mining of 7TMR proteins
Creators: name: Jones, Alan M.
Publisher: name: BioMed Central Ltd
Year: 2009

description: Abstract Background Seven-transmembrane region-containing receptors (7TMRs) play central roles in eukaryotic signal transduction. Due to their biomedical importance, thorough mining of 7TMRs from diverse genomes has been an active target of bioinformatics and pharmacogenomics research. The need for new and accurate 7TMR/GPCR prediction tools is paramount with the accelerated rate of acquisition of diverse sequence information. Currently available and often used protein classification methods (e.g., profile hidden Markov Models) are highly accurate for identifying their membership information among already known 7TMR subfamilies. However, these alignment-based methods are less effective for identifying remote similarities, e.g., identifying proteins from highly divergent or possibly new 7TMR families. In this regard, more sensitive (e.g., alignment-free) methods are needed to complement the existing protein classification methods. A better strategy would be to combine different classifiers, from more specific to more sensitive methods, to identify a broader spectrum of 7TMR protein candidates. Description We developed a Web server, 7TMRmine, by integrating alignment-free and alignment-based classifiers specifically trained to identify candidate 7TMR proteins as well as transmembrane (TM) prediction methods. This new tool enables researchers to easily assess the distribution of GPCR functionality in diverse genomes or individual newly-discovered proteins. 7TMRmine is easily customized and facilitates exploratory analysis of diverse genomes. Users can integrate various alignment-based, alignment-free, and TM-prediction methods in any combination and in any hierarchical order. Sixteen classifiers (including two TM-prediction methods) are available on the 7TMRmine Web server. Not only can the 7TMRmine tool be used for 7TMR mining, but also for general TM-protein analysis. Users can submit protein sequences for analysis, or explore pre-analyzed results for multiple genomes. The server currently includes prediction results and the summary statistics for 68 genomes. Conclusion 7TMRmine facilitates the discovery of 7TMR proteins. By combining prediction results from different classifiers in a multi-level filtering process, prioritized sets of 7TMR candidates can be obtained for further investigation. 7TMRmine can be also used as a general TM-protein classifier. Comparisons of TM and 7TMR protein distributions among 68 genomes revealed interesting differences in evolution of these protein families among major eukaryotic phyla.

description: Invariant solutions of shear flows have recently been extended from spatially periodic solutions in minimal flow units to spatially localized solutions on extended domains. One set of spanwise-localized solutions of plane Couette flow exhibits homoclinic snaking, a process by which steady-state solutions grow additional structure smoothly at their fronts when continued parametrically. Homoclinic snaking is well understood mathematically in the context of the one-dimensional Swift-Hohenberg equation. Consequently, the snaking solutions of plane Couette flow form a promising connection between the largely phenomenological study of laminar-turbulent patterns in viscous shear flows and the mathematically well-developed field of pattern-formation theory. In this paper we present a numerical study of the snaking solutions, generalizing beyond the fixed streamwise wavelength of previous studies. We find a number of new solution features, including bending, skewing, and finite-size effects. We show that the finite-size effects result from the shift-reflect symmetry of the traveling wave and establish the parameter regions over which snaking occurs. A new winding solution of plane Couette flow is derived from a strongly skewed localized equilibrium.

description: The electronic and transport properties of the half-Heusler compound LaPtSb are investigated by performing first-principles calculations combined with semi-classical Boltzmann theory and deformation potential theory. Compared with many typical half-Heusler compounds, the LaPtSb exhibits obviously larger power factor at room temperature, especially for the n-type system. Together with the very low lattice thermal conductivity, the thermoelectric figure of merit (ZT) of LaPtSb can be optimized to a record high value of 2.2 by fine tuning the carrier concentration.

As an alternative approach, the oxide heterostructures may evade the intrinsic limits in bulk materials and provide more attractive potential to realize the magnetoelectric functions. Here we perform a first-principles study on LaAlO$_3$/PbTiO$_3$ superlattices. Although neither of the components is magnetic, magnetic moments emerge at the ferroelectric domain walls of PbTiO$_3$ in these superlattices. Such a twist between ferroelectric domain and local magnetic moment, not only manifests an interesting type of multiferroicity, but also is possible useful to pursuit the electrical-control of magnetism in nanoscale heterostructures.

description: The Kilo-Degree Survey (KiDS) is an optical wide-field survey designed to map the matter distribution in the Universe using weak gravitational lensing. In this paper, we use these data to measure the density profiles and masses of a sample of $\sim \mathrm{1400}$ spectroscopically identified galaxy groups and clusters from the Galaxy And Mass Assembly (GAMA) survey. We detect a highly significant signal (signal-to-noise-ratio $\sim$ 120), allowing us to study the properties of dark matter haloes over one and a half order of magnitude in mass, from $M \sim 10^{13}-10^{14.5} h^{-1}\mathrm{M_{\odot}}$. We interpret the results for various subsamples of groups using a halo model framework which accounts for the mis-centring of the Brightest Cluster Galaxy (used as the tracer of the group centre) with respect to the centre of the group's dark matter halo. We find that the density profiles of the haloes are well described by an NFW profile with concentrations that agree with predictions from numerical simulations. In addition, we constrain scaling relations between the mass and a number of observable group properties. We find that the mass scales with the total r-band luminosity as a power-law with slope $1.16 \pm 0.13$ (1-sigma) and with the group velocity dispersion as a power-law with slope $1.89 \pm 0.27$ (1-sigma). Finally, we demonstrate the potential of weak lensing studies of groups to discriminate between models of baryonic feedback at group scales by comparing our results with the predictions from the Cosmo-OverWhelmingly Large Simulations (Cosmo-OWLS) project, ruling out models without AGN feedback.

description: To search for optical variability on a wide range of timescales, we have carried out photometric monitoring of 3C 454.3, 3C 279 and S5 0716+714. CCD magnitudes in B, V, R and I pass-bands were determined for $\sim$ 7000 new optical observations from 114 nights made during 2011 - 2014, with an average length of $\sim$ 4 h each, at seven optical telescopes. We measured multiband optical flux and colour variations on diverse timescales. We also investigated its spectral energy distribution using B, V, R, I, J and K pass-band data. We discuss possible physical causes of the observed spectral variability.

Trophic ecology of glass sponge reefs in the Strait of Georgia, British Columbia

Sponges link the microbial loop with benthic communities by feeding on bacteria. Glass sponge reefs on the continental shelf of western Canada have extremely high grazing rates, consuming seven times more particulate carbon than can be supplied by vertical flux alone. Unlike many sponges, the reef building species Aphrocallistes vastus has no microbial symbionts and removes little dissolved organic carbon. To determine how reef sponges therefore get enough food to sustain such substantial grazing we measured stable carbon and nitrogen isotope signatures of water, sediment and sponge tissues.

To ensure samples were temporally associated, we also studied the duration particles were retained in tissues in controlled feeding studies using microscopic beads and 13C-labeled bacteria. Although fecal pellets were expelled from sponges within 24 hours of feeding, intact bacteria were still found in tissues and sponge tissues retained elevated 13C levels for at least 14 days. These independent lines of evidence suggest that carbon in reef sponge tissues may reflect food consumed from days to weeks earlier. Stable isotope analysis suggests that heterotrophic bacteria ingested by the sponges comes from a confluence of trophic subsidies: from terrestrial and oceanic sources, and also potentially on sediment-borne bacteria resuspended by tidal currents.

description: We demonstrate, at room temperature, the strong coupling of the fundamental and non-uniform magnetostatic modes of an yttrium iron garnet (YIG) ferrimagnetic sphere to the electromagnetic modes of a co-axial cavity. The well-defined field profile within the cavity yields a specific coupling strength for each magnetostatic mode. We experimentally measure the coupling strength for the different magnetostatic modes and, by calculating the expected coupling strengths, are able to identify the modes themselves.

description: New experimental data on transverse momentum spectra of strange particles (KS0, K-, K*, phi,...) produced in pp collisions at sqrt s = 200 GeV obtained by the STAR and PHENIX collaborations at RHIC are analysed in the framework of z-scaling approach. Scaling properties of the data z-presentation are illustrated. Self-similarity of strange particle production is discussed. A microscopic scenario of constituent interactions developed within the z-scaling approach is used to study constituent energy loss, proton momentum fraction and recoil mass in dependence on the transverse momentum, strangeness, and mass of the inclusive particle. The obtained results can be useful for understanding strangeness origin, for searching for new physics with strange probes and can serve as a benchmark for complex analyses of self-similar features of strange production in heavy ion collisions.

description: Due to the increasing prevalence of cosmetic surgeries, it seems necessary to investigate the psychological factors involved in this issue. Therefore, the present study aimed to investigate the relationship between social anxiety and the desire for cosmetic surgery (DCS) through the mediating role of body image and appearance-based rejection sensitivity (ABRS). This was a correlational study, of structural equation modeling (SEM) type. The statistical population included all students studying at universities of Kermanshah, Iran in the academic year 2020-2021, out of whom 326 were selected through convenience sampling method. Participants filled out Henderson-King’s attitudes towards cosmetic surgery, Connor et al.’s social phobia, Littleton et al.’s fear of body image, and Park’s ABRS questionnaires. Pearson’s correlation coefficient and SEM were used in LISREL8.8 and SPSS-22 software to analyze the data. The results revealed that the hypothesized model had a good fit in the study sample. It was also found that the avoidance and physiological distress components of social anxiety are related to DCS through body image and ABRS, respectively. Accordingly, measures to increase knowledge about psychological factors, especially social anxiety, affecting DCS in cosmetic physicians and clients of beauty clinics, are recommended.

description: Expert and practitioner views of the contributions made by universities and schools to initial teacher preparation in England. In November 2010, the coalition government published its seminal The White Paper, The Importance of Teaching. Its recommendations sought to reform Initial Teacher Training (ITT) so that more training was school-based; to create a new national network of ‘Teaching Schools’ that gave outstanding schools in England a leadership role in the initial training and professional development of teachers. This thesis critically analyses the subsequent changes in relationships and tensions between universities and schools as the reforms were implemented. The consequent increase in the number of routes into teaching, coupled with more autonomy devolved to schools in relation to Initial Teacher Preparation (ITP), has served to jeopardise university-based preparation. The changing notions of pedagogy and practice in school-led initial teacher preparation alter the significance of theory in ITP and ultimately question the future for university-led initial teacher education. What constitutes effective teacher preparation is explored through a series of semi-structured interviews drawn from a small, reputational sample across the field of education. This provides the data that reveals a contemporary dichotomy between ‘training’ and ‘education’ that challenges the relevance of a theoretically informed teacher education in favour of ‘on the job training.’ From the discussion of the contested data provided by reputational sample, an outcome of the current changes could result in a peripheral role for universities in ITP. In particular, undergraduate provision, such as the B.Ed, was threatened because it did not provide a sufficient depth of subject knowledge; a shift to post-graduate school-based preparation and a reliance on assessment-only routes renders the role of the universities defunct. The findings from the analysis of the reputational sample were further examined in the workplace through questionnaire given to academics and partnership school mentors working in delivering ITP in an East Midlands University. The tensions between ‘training’ and education and the role of universities in initial teacher preparation were mirrored by teachers and academics. In conclusion, the changes made by the coalition government have made the future of ‘teacher education’ uniquely fragile.
