Environmental characteristics and changes of bacterial communities in the meltwater runoff of glacier in Ny-Alesund, Arctic

The present study assessed the diversity and composition of bacterial communities in glacial runoff and glacial soils in the Midre Lovénbreen glacier region of Svalbard. A total of 6,593 operational taxonomic units were identified by high-throughput sequencing. The results showed differences in bacterial community composition between the upper and lower reaches of glacial runoff. The abundance of Actinobacteria, Firmicutes, Betaproteobacteria and Gammaproteobacteria in the upper reaches of glacial runoff was higher than that in the lower reaches. In contrast, the the abundance of Cyanobacteria and Alphaproteobacteria in the downstream of glacial runoff was higher than that in the upstream. In addition, we compared bacterial diversity and composition between glacial runoff areas and soils. The chart analysis showed that bacterial diversity in glacial soil was higher than that in the glacial runoff. Some typical bacteria in the soil, such as Actinobacteria, entered glacial runoff through contact between them. The abundance of Acidobacteria, Sphingobacterium and Flavobacterium was higher in glacial soil. Weighted correlation network analysis showed that the core bacteria in glacial runoff and glacial soil were typical bacteria in different habitats. Distance-based redundancy analysis revealed that NO 2 - -N was the most significant factor affecting the distribution of soil bacterial community, while NO 3 - -N was the most significant factor affecting the distribution of glacial runoff bacterial community.
Carbon Sequestration Potential of Cropland at Different Doses of Composts in Southern Togo

The objective of this study was to assess the carbon sequestration potential of cropland amended at different doses of solid household waste compost. Field experiments were conducted during four cropping seasons alternating maize and tomato. Soil samples were collected on experimental plots in 20 cm depth for soil organic carbon content determination using wet oxidation method while bulk density was measured by the core method (volumetric cylinder method) with undisturbed soil samples taken in 0 - 20 cm with steel cylinder of 100 cm3. Carbon sequestration potential varied with carbon content, bulk density and soil depth. The results shown that amount of carbon sequestered under maize cultivation (0.035±0.03 to 0.191±0.03 t C ha-1) was higher than those recorded under tomato growing areas (0.016±0.03 to 0.164±0.02 t C ha-1). Carbon sequestration rates ranged from 0.105±0.01 to 0.573±0.01 t C ha-1 yr-1 under maize cultivation and from 0.048±0.02 to 0.492±0.03 t C ha-1 yr-1 under tomato growing. It is able to conclude that household waste compost application contributes to increase carbon accumulation in soil.
Quasi-Liquid Crystals of Electrons and Positrons

A new statistical analysis of infrared synchrotron radiation (IR-SR)emitted by electrons and positrons at DAΦNE Φ-Factory (Frascati) and Bessy 2(Berlin) reveals inner degrees of freedom within bunches of relativistic particles.We thus propose a new methodological approach towards a theory that describesthe passage from a phase of maximum symmetry to a condensed phase having thequalities of a nematic mesophase of positrons and electrons.
A Newly Discovered Late‐Cretaceous East Asian Flat Slab Explains Its Unique Lithospheric Structure and Tectonics

The existence of historical flat slabs remains debated. We evaluate past subduction since 200 Ma using global models with data assimilation. By reproducing major Mesozoic slabs whose dip angles satisfy geological constraints, the model suggests a previously unrecognized continental‐scale flat slab during the Late Cretaceous beneath East Asia, a result independent of plate reconstructions, continental lithospheric thickness, convergence rate, and seafloor age. Tests show that the pre‐Cretaceous subduction history, both along the western Pacific and Tethyan trenches, is the most important reason for the formation of this prominent flat Izanagi slab. Physically, continuing subduction increases the gravitational torque, which, through balancing the suction torque, progressively reduces dynamic pressure above the slab and decreases the slab dip angle. The flat Izanagi slab explains the observed East Asian lithospheric thinning that led to the formation of the North‐South Gravity Lineament, tectonic inversion of sedimentary basins, uplift of the Greater Xing'an‐Taihang‐Xuefeng mountains and the abrupt termination of intraplate volcanism during the Late Cretaceous.
Characters of a nitrobacter enrichment culture from a freshwater aquaculture pond

Abstract To isolate nitrite-oxidizing bacteria to control the nitrite concentration in freshwater aquaculture systems, a Nitrobacter enrichment culture was obtained from a freshwater shrimp pond using a continuous enrichment and gradient dilution method. There was only one species of Nitrobacter in the enrichment culture, with an abundance of more than 99%. The Nitrobacter strain was identified as Nitrobacter vulgaris XY-12 on the basis of its 16S rRNA gene and NxrA gene sequences. The effects of pH, temperature, salinity and nitrate on the nitrification activity of the enrichment culture were examined, and its ability to remove nitrite in aquaculture water was also tested. The results showed that the optimum pH for the nitrite-oxidation activity of the enrichment culture was 7.5, the optimum temperature range was 27 °C–30 °C, the optimum salinity was 0.38%, the half maximal inhibitory concentration (IC50) of NO3 −–N was 400 mg L −1, and the optimum concentration of NO2 −–N was 200 mg L −1. In optimum conditions, the maximum NO2 −–N removal rate afforded by the enrichment was 1.62 mg L −1 h −1, and the minimum doubling time was 12 ± 2 h. Moreover, XY-12 could multiply in field aquaculture water, and the maximum NO2 −–N removal rate was 0.15 mg L −1 h −1. These results indicated that the enrichment had good application prospects in aquaculture waters.
IMPACT OF TRANSCATHETER CLOSURE OF ATRIAL SEPTAL DEFECT ON RIGHT VENTRICULAR SIZE AND FUNCTION BY ECHOCARDIOGRAPHY

Background: Percutaneous atrial septal defect (ASD) device closure is a safe and effective means of reducing or eliminating interatrial shunting. The response of the right heart to device closure is incompletely understood. Objective: To evaluate the effects of transcatheter closure of secundum ASD on right ventricle size and function, that is, both systolic and diastolic by transthoracic echocardiography (TTE) over a 6 month period. Patients and Methods: One hundred patients had 100 device implantations. The patients were assessed with echocardiography before, at 1 and 6 months after procedure, at Bab Al-Shaareya Hospital of Al-Azhar University, and National Heart Institute, Egypt during the period from April 2017 to October 2019. Results: Mean age was (12.62±11.39 years). Maximum ASD size indexed to body surface area (BSA) was (Mean±SD=17.88±5.08 mm/m2). The device size ranged from 11 mm to 31 mm. There was significant decrease from baseline to 1 month and baseline to 6 months after closure In the following indexed parameters: RV basal, mid, longitudinal diameters I, RV end diastolic area I, RV/LV end diastolic dimension ratio, RA end systolic area I and Estimated systolic pulmonary artery pressure (ESPAP), Also parameters of RV systolic functions such as; tricuspid annular plane systolic excursion (TAPSE), tricuspid annular systolic velocity (TASV or S/) and fractional area change (FAC%), and diastolic dysfunction parameters; E/A and E/e/, (p=0.001). while RV index of myocardial performance (RIMP) showed significant reduction at one month (0.39±0.03 vs. 0.35±0.02; p=0.001) and non-significant change at six months in comparison to baseline (p=0.083). Conclusion: RV volumes decreased significantly in the first month after ASD device closure and continued up to 6 months. There was no change in global right ventricular systolic function but a high basal RV systolic function decreased after closure. Some patients had impaired diastolic function before closure of defect, which reversed to normal within 6 months after closure.
Diversion as a pathway to improving service utilization among at-risk youth.

Despite the high rates of mental illness among youth in the juvenile justice system, many justice-involved youth do not receive adequate behavioral health services. We examined differences in health service utilization outcomes between youth who were diverted through a community-based, precom-plaint program (Safety Net; n = 41), and youth with juvenile justice involvement in neighboring cities ( n = 154). Individual arrest and health care records were combined to evaluate the rate of health care service utilization before and after initial police contact. A difference-in-differences approach with propensity score weighting was used to evaluate the impact of Safety Net on health service use, including inpatient, outpatient, emergency department (ED), and primary care visits. Compared to their nondi-verted counterparts, Safety Net youth had a signi ﬁ cant increase in psychiatric outpatient visits (average treatment effect [ATE] of 26%; p , .05) and psychiatric outpatient and primary care visits among those with a diagnosed mental illness (ATE of 19% and 12%, respectively); p , . 05). There were no signi ﬁ - cant differences in ED or hospitalization outcomes. Results suggest that precomplaint diversion through Safety Net fosters access to outpatient behavioral health and primary care services that address the underlying issues that put youth in contact with police.
Public choice and decentralised healthcare service delivery in Lesotho: Assessing improvement and efficiency in service delivery

Abstract Providing efficient decentralised local public services such as healthcare in hard to reach and remote areas has been the recent concern of public finance experts. Thus public finance theory, the public choice, has been devoted to explain the link between decentralised local public service delivery and efficiency. The theory argues that efficient delivery of decentralised local public service is achieved through the proximity advantage of local management boards, which enables them (that is the local management boards) to provide services tailored to the needs of their respective local communities. Using the public choice’s decentralised local service provision, this study adopted a qualitative design, and accidentally selected and interviewed 40 health service users (HUs) and 10 Health professions (HP) in the rural areas of Lesotho. The results show improvement and efficiency in healthcare service accessibility, utilisation and affordability in the study communities. Again, it emerged that decentralised healthcare delivery helped healthcare service providers to gain an in-depth knowledge of the healthcare needs of the local people, thereby enabling them to adjust services to the healthcare needs of the community through innovative healthcare delivery strategies, like mobile healthcare delivery service and the mobilisation of trained assistant nurses deployed to serve in remote and hard-to-reach communities. Results further show that these innovative healthcare strategies meet the health needs and preferences of the local people. The study recommends local and central governments to prioritize and scale up decentralised healthcare delivery across the country, particularly in vulnerable and poor communities, in addition to the provision of state-of-the-art healthcare facilities and intensified human resource training for the healthcare sector.
The Influence of Romanian Mobile Commerce Companies on Developing Green Innovation

Lately, concern for green innovation has expanded in the business environment and many companies see it as a helpful element to gain competitive advantage. Due to the strains of maintaining sustainable businesses, mobile commerce companies are propelled to build up their own green innovation programs and harmonize them with the firm’s management programs. The central scope of this research is to examine the drivers for green innovation within a range of Romania-based mobile commerce companies that operate in different industries. With the aim of identifying the factors that determine the development of green innovation, a conceptual model has been conceived. The dependent variable within the model is the action of the company’s management to develop green innovation. Four independent types of variable structures that have an impact on the development of green innovation in mobile commerce firms were distinguished. The four categories of constructs are business environmental factors (1), green training (2), green supplier development (3), and technological factors (4). An online survey tested the model based on the responses of senior level management representatives from 182 Romanian mobile commerce companies from Bucharest. The validity of the model was fulfilled though factor analysis and reliability tests for the data; a logistic regression analysis was also used to test the research hypotheses. The research revealed that green training embodies the fundamental element enhancing green innovation among Romanian mobile commerce companies. This article benefits both academia and business. Firms could be inspired by the results of this paper to broaden the level of green innovation throughout the Romanian business environment.
Modeling Photosynthesis and Exudation in Subtropical Oceans

Marine phytoplankton contributes nearly half of the total primary production on Earth through photosynthesis. Parameterizations of algal photosynthesis commonly employed in global biogeochemical simulations generally fail to capture the observed vertical structure of primary production. Here we examined the consequences of decoupling photosynthesis (carbon fixation) and biosynthesis (biomass building) with accumulation or exudation of excess photosynthate under energy rich conditions in both regional and global models. The results show that the decoupling of these two processes improved the simulated vertical profile of primary production, increased modeled primary production over 30% globally and over 40% in subtropical oceans, improved simulated meridional patterns of particulate C:N:P and increased modeled surface pool of labile/semi‐labile dissolved organic carbon. More generally, these results highlight the importance of exudation, which results from the decoupling of photosynthesis and biosynthesis, as a major physiological process affecting ocean biogeochemistry.
Animal Production

This book, just published, reports the most recent advances in the study of production disease. The term " production disease " includes a number of metabolic disorders of increasing importance in agriculture, some of which, such as milk fever, grass tetany, and ketosis, are well known whereas others are relatively new and obscure. A breakdown occurs in the health of the animals in all these disorders due either to imbalances between the " input" and " output" of the metabolites required for production or to deviations from normal in the " throughput " pathways of the body. The three aspects, input, output, and throughput, were the themes of the International Conference on Production Disease held at Reading University, the Grassland Research Institute, the National Institute for Research in Dairying, and the Institute for Research on Animal Diseases in July 1972. This conference enabled scientists of many disciplines such as nutrition, biochemistry, physiology, endocrinology, radiobiology, and veterinary science to meet and make a unified approach to the solution of production disease. The proceedings presented in this book, although primarily directed towards the research scientist, are of great interest to agriculturalists, veterinary students, farmers, and other persons who are concerned about the potential health hazards associated with intensive management. This is a stimulating account of the ways in which beef is produced in the 1970s. It has been written in the light of rapid advances in our knowledge of ruminant nutrition and of changes in meat marketing and consumer requirements. The aim of the book is to guide students and farmers on the more important factors which affect the biological and economic efficiency of beef production. Modern systems of beef production and recent developments in beef cattle management are discussed and described.
Slot Antenna Miniaturization Using Folded Slot for ISM Band Applications

A novel antenna miniaturization technique of microstrip-fed slot antenna, using a folded slot topology, is highlighted. Antennas are designed with slits on both sides of folded slot and metallic strips on the bottom of the substrate. An unfolded radiating slot of 30.00 mm length is folded to 15.44 mm, without compromising the radiation pattern or return loss characteristics. The proposed antenna exhibits 60.27% reduction in resonant frequency for slits and strips’ loaded folded slot topology in comparison with 48.01% reduction in resonant frequency of previous works. These antennas also offer improved impedance bandwidth. The gain performances of these antennas are improved by placing a dielectric slab on the bottom of the substrate without compromising the radiation pattern characteristics.
The influence of family support during endoscopic submucosal dissection on patient's anxiety

Background Psychological problems may promote peptic ulcers. Ulcer-like wounds can be formed after gastric endoscopic submucosal dissection (ESD). The influence of family support on the healing of gastric ESD-induced ulcers remains largely undetermined. Objective In the present study, we aimed to assess the Hospital Anxiety and Depression Scale (HADS) scores and the incidence of post-ESD complications in patients with family support in the care process and those in the non-relative group. Materials and methods A total of 191 patients aged between 30 and 70 years who received gastric ESD were evaluated with the Chinese version of HADS. Differences in depression and anxiety between the two groups were compared using the chi-square test and t-test. Multivariable logistic regression models were used to examine whether anxiety and depression were the risk factors for post-ESD complications. Results The mean values of HADS-A (4.61 ± 2.89 vs. 5.56 ± 3.07, p = 0.042) and HADS-D (4.14 ± 3.03 vs. 4.97 ± 2.61, p = 0.048) scores were significantly lower in patients with accompanying relatives compared with those in the non-relative group. Besides, through the pre-ESD and post-ESD self-contrast, the scores of anxiety and depression in the relative-group were 0.57 and 0.56, respectively (p < 0.001), while those in the non-relative group were increased by 1.43 and 1.49, respectively (p < 0.001). Multivariable logistic regression analysis revealed that HADS-A, HADS-D scores, and age were significantly correlated with post-ESD abdominal pain (P < 0.05). Conclusions The occurrence and degree of adverse emotions such as psychological anxiety and depression in patients who received gastric ESD with accompanying relatives during hospitalization may were reduced, and the incidence of gastric post-ESD abdominal pain may was also decreased.
Consecutive Independence and Correlation Transform for Multimodal Data Fusion: Discovery of One-to-Many Associations in Structural and Functional Imaging Data

Brain signals can be measured using multiple imaging modalities, such as magnetic resonance imaging (MRI)-based techniques. Different modalities convey distinct yet complementary information; thus, their joint analyses can provide valuable insight into how the brain functions in both healthy and diseased conditions. Data-driven approaches have proven most useful for multimodal fusion as they minimize assumptions imposed on the data, and there are a number of methods that have been developed to uncover relationships across modalities. However, none of these methods, to the best of our knowledge, can discover “one-to-many associations”, meaning one component from one modality is linked with more than one component from another modality. However, such “one-to-many associations” are likely to exist, since the same brain region can be involved in multiple neurological processes. Additionally, most existing data fusion methods require the signal subspace order to be identical for all modalities—a severe restriction for real-world data of different modalities. Here, we propose a new fusion technique—the consecutive independence and correlation transform (C-ICT) model—which successively performs independent component analysis and independent vector analysis and is uniquely flexible in terms of the number of datasets, signal subspace order, and the opportunity to find “one-to-many associations”. We apply C-ICT to fuse diffusion MRI, structural MRI, and functional MRI datasets collected from healthy controls (HCs) and patients with schizophrenia (SZs). We identify six interpretable triplets of components, each of which consists of three associated components from the three modalities. Besides, components from these triplets that show significant group differences between the HCs and SZs are identified, which could be seen as putative biomarkers in schizophrenia.
Design of an Efficient Trustful-Lightweight Cloud Service Provisioning Model using Service Optimizer

INTRODUCTION: The establishment of trusted cloud services pretends to provide high impactful service with better satisfaction to the web-users and cloud service providers. Moreover, various existing trust-aware algorithms use diverse QoS measurements and related attributes, leading to the complex selection of cloud services. OBJECTIVES: Thus, this research intends to propose a Trustful-Lightweight Cloud Service Provisioning algorithm (TL-CSP) using Service Optimizer (SO). METHODS: Initially, the QoS metrics are determined by evaluating attributes based on a ranking method based on the users' requests. It is performed with the computation of weighted coefficients of received requests from the users. The service optimization is performed using a global optimizer to assist the cloud users in selecting the service with better satisfaction. RESULTS: The proposed TL-CSP accuracy is validated and compared with the existing cloud service provisioning algorithm to measure the proposed model's efficiency. CONCLUSION: The simulation is carried out in a MATLAB environment. The proposed TL-CSP intends to shows a better trade-off in contrast to prevailing approaches.
Zooglider‐measured association of zooplankton with the fine‐scale vertical prey field

We use Zooglider, a low‐power optical zooplankton‐sensing glider, to test the covariability of the fine‐scale vertical distributions of six omnivorous zooplankton taxa with three different representations of their potential prey field: small suspended particles (equivalent circular diameter [ECD] between 0.25 and 0.45 mm), marine snow (ECD ≥ 0.45 mm), and chlorophyll a (Chl a), in the San Diego Trough. All three prey fields tend to be highly correlated from 100 m to the depth of the subsurface Chl a maximum layer (SCML), while correlations between the prey fields are weaker or nonexistent from the SCML to the surface. An index of spatial overlap (Local Index of Collocation) showed stronger overlap of zooplankton with marine snow or small particles than with Chl a in most cases. Moreover, generalized additive models revealed marine snow distributions or small particles as the primary explanatory variable, by percent deviance explained, for all zooplankton taxa tested. Chl a distributions were a secondary explanatory variable for four of the six taxa tested (small copepods, appendicularia‐Fritillaria, and both night and day large copepods), and an insignificant explanatory variable for the remaining two (appendicularia‐others and large protists). The distributions of suspended particles, during our year‐round study in the San Diego Trough, were more informative for explaining distributions of omnivorous zooplankton than Chl a alone.
