Evaluation of ocular trauma score in open globe injuries

Purpose: To evaluate the epidemiological characteristics and ocular trauma scores (OTSs) of open globe injuries and to determine other factors that may affect OTS. Materials and Methods: Patients who were diagnosed with open eye injuries, treated and followed up between July 2018 and July 2020 were retrospectively evaluated. The demographic features, injury type, initial and final visual acuity (Snellen chart), ophthalmoscopic examinations, hospitalization days and number of operations were recorded. OTSs were determined as described by Kuhn et al. in 2002. Results: Forty-two patients, 12 of whom were female (28.6%), were included in the study. The mean age of the patients was 42.9 ± 19.4 (7-90). While the best corrected visual acuity of the patients at presentation was 0.038 ± 0.13 (Snellen line), it was evaluated as 0.37 ± 0.39 (Snellen line) at the final examination. When compared with the OTS study group, statistically significant differences were found in final VA. A statistically significant difference was found in the light perception (LP) (-) and 1/200-19/200 VA subgroups in Category 1 (p <0.001). In Category 2 only the final VA between 1/200-19/200 was insignificant. In Category 3 the final VA of 68% patients was 20/40, or better; and 16% of the patients was between 20/200-20/40. Also, none of our patients had LP or hand motion (0%) at the end. All three values in Category 3 were statistically significantly different, either. The OTS was lower in eyes with iris damage (such as those with iris sphincter rupture, iridodialysis or iris defect) and in eyes with vitreous loss. Conclusion: OTS provides prognostic information after ocular trauma and is reliable and applicable in the management of open globe injuries. It is open for improvement by adding different parameters. Other factors, such as iris damage and vitreous loss, that may negatively affect final visual acuity have to be considered in the rearrangement of OTS.
Effect of the content of silane-functionalized boron carbide on the mechanical and wear performance of B4C reinforced epoxy composites

This article presents the mechanical, physical, and tribological properties of the boron carbide (B4C) reinforced epoxy matrix composites (BEMCs). The BEMC samples were prepared with various B4C concentration of 0%, 1%, 2%, 3%, and 5%. B4C particles were treated with a silane coupling agent to ensure efficient adhesion with epoxy. The influence of a range of parameters (particle loading, sliding speed, sliding distance, and normal load) on the wear and friction behavior of BEMCs were evaluated by conducting wear tests under dry sliding conditions on a pin-on-disc wear test set-up. The addition of B4C to the epoxy polymer improved the wear resistance of the composites. Maximum wear resistance and coefficient of friction were observed for the composite with the highest percentage of B4C (5%). The specific wear rate was reduced on increasing load and sliding distance and increased with the sliding velocity. Mechanical properties including compression strength, flexural strength, and impact energy, along with physical properties such as density and hardness, were also evaluated. B4C particles improved the hardness, density, flexural and compression strength, and impact resistance of the composites. Scanning electron microscope (SEM) analysis of the worn-out surfaces and flexural fractured surfaces was carried out to predict the possible wear and fracture mechanisms. Micro-ploughing, abrasion, and adhesion were the wear mechanisms in BEMCs. Under the flexural loads, particulate de-bonding, pull-out, and brittle fracture of the matrix were the governing failure mechanisms.
Crop Establishment Methods and Integrated Nutrient Management Improve: Part II. Nutrient Uptake and Use Efficiency and Soil Health in Rice (Oryza sativa L.) Field in the Lower Indo-Gangetic Plain, India

Rice, the predominant food crop in India, is being grown traditionally with improper plant nutrient management mostly under the flooded situation. Recent advancement in research on crop science focuses on water-saving rice technologies for maximization in crop and water productivity under the backdrop of a shrinking water resource base for ensuring environmental and agricultural sustainability. Under this situation, an experiment was conducted in two consecutive years in a split-plot design keeping rice cultivation methodologies, viz., aerobic culture, System of Rice Intensification (SRI), and conventional flooded culture in main plots and integrated plant nutrient management (INM) treatments in sub-plots. The experiment was aimed at understanding the effects of different rice production systems and INM on nutrient content, uptake, and use efficiency. The change in soil quality parameters was also studied to understand the impact of crop establishment methods (CEM) and INM options. Significant reduction (p ≤ 0.05) in nutrient uptake and use efficiency was observed under aerobic culture compared to SRI and flooded method, although aerobic culture showed the highest physiological nitrogen use efficiency. Post-harvest available Fe status was significantly lower in aerobic rice (mean 10.39 ppm) compared to other crop establishment technologies; however, Zn status was higher in aerobic rice over the flooded situation. Although available potassium was not affected due to rice cultivation methods, available nitrogen and phosphorus status were influenced remarkably. Soil microbial quality was improved in aerobic rice in comparison to flooded rice. SRI proved to be the most efficient rice establishment method for enhancement in nutrient uptake, use efficiency, and enrichment of soil chemical and microbiological quality. Irrespective of crop culture, integrated plant nutrition in rice improved the nutrient uptake, use efficiency, and soil quality parameters. The study revealed that, under the alluvial soils of the Indo-Gangetic Plains of Eastern India, SRI can be considered as a water-saving rice production method. The method can also improve nutrient uptake, efficiency, and soil quality parameters if proper INM is adopted.
Effects of Lead on Growth and Mineral Nutrition of Wheat (Triticum Aestivum L.) As Influenced by Manure and Lime

A pot experiment was conducted to evaluate the effects of four levels of lead (50, 100, 150 and 200 mg/kg) treatment on wheat (Triticum aestivum L.) and its amelioration by cowdung, poultry litter and lime. The lengths, fresh and dry weights of shoot and root decreased with increasing level of lead as well as the macronutrients compared to the control. The maximum reduction was observed in the pots treated with 200 mg/kg lead. The highest reduction in macronutrient content was also observed in 200 mg/kg Pb treated pot whereas N, P, K, Ca and Mg concentration was reduced by 0.41, 0.019, 1.15, 0.38 and 0.071% for shoot and 0.512, 0.071, 0.17, 0.51 and 0.122% for root, respectively. Lead concentration in roots and shoots increased with increasing level of lead treatment compared to the control. Cowdung was shown to be most effective, followed by poultry litter and lime. This particular organic manure had considerably greater decreasing impacts in lead uptake by wheat crops. Cowdung treated pots increased fresh and dry weight by 14.56 and 13.28% for grain, 7.58 and 7.08% for shoot and 2.41 and 2.06% for root compared to pot treated with 100 mg/kg lead. J. Biodivers.

FLAXSEED MEAL FEEDING TO DAIRY COWS AS A STRATEGY TO IMPROVE MILK ENTEROLACTONE CONCENTRATION: A LITERATURE REVIEW

ABSTRACT: Flaxseed (Linum usitatissimum) is the richest source of the plant lignan secoisolariciresinol diglucoside (SDG). In mammals, including bovine, SDG is converted to the mammalian lignans enterolactone (EL) and enterodiol (ED) by the action of gastrointestinal microbes. There is a great deal of interest in promoting increased intakes of lignans in humans’ diet due to the potential health benefits of mammalian lignans, especially in the prevention of cardiovascular diseases, hypercholesterolaemia, breast and prostate cancers, and osteoporosis. Consumption of milk and dairy products enriched in EL could be an excellent strategy to increase the intake of lignans by humans. This literature review will focus on presenting feeding strategies capable to improve milk enterolactone concentration. Research has demonstrated the potential of flaxseed meal (FM) feeding to dairy cows as a strategy to improve milk EL concentration, therefore enhancing milk nutraceutical proprieties. A considerable number of studies have demonstrated that feeding vegetable lignans-rich sources, such as FM, to dairy cows improves EL in milk. Additionally, it has been reported that changes in the carbohydrate profile of FM-based diets fed to dairy cows can alter the output of milk EL. The application of animal nutrition as a tool to increase nutraceutical properties of milk (i.e. increased EL concentration) is a valuable strategy for promoting the association of milk with humans’ health benefits and is of great interest in contemporary society. Keywords: nutraceutical proprieties, bioactive compounds, lignans, dairy cows, disease risk reduction
Food Insecurity and Related Factors among Farming Families in Takhar Region, Afghanistan

Improved food security remains a major challenge for policymakers in Afghanistan. The objective of this study is to investigate the prevalence and drivers of food insecurity among farming households in the Takhar region of Afghanistan. Household questionnaire survey datasets were obtained from 262 farmers via multi-stage sampling across four districts. The Household Food Insecurity Access Scale (HFIAS) was constructed to assess the prevalence of food insecurity, and an ordered probit econometric model was used to identify the factors influencing the prevalence rates in farming families. The findings indicate that 66.79% of the farming households were food insecure, whilst 30.53% were severely food insecure. After adjustment of socio-economic and demographic characteristics of families, the ordered probit results reveals that household head education, dependency ratio, farm income, access to non-agricultural income, livestock unit, group membership, borrowing, farm diseases, flood, and war significantly influenced farming households’ food insecurity in the study area. Our findings highlight the urgent requirement for policies and initiatives to support farmers to improve their overall food security. Such strategies should focus on introducing improved farming techniques, enhancing farmer education levels, livestock development programs, building and empowering farmers groups, creating credit access to households, and providing humanitarian food support.
The Hidden Side of Adoption in Catalonia: When Adoption Breaks down

Abstract Rates of adoption breakdown have often been underestimated in international adoption. While several relevant studies have been published in Spain, there is no research addressing this issue in the autonomous community of Catalonia, which has been one of the main centers of international adoption in Spain since the 1990s. Our research provides specific data on this phenomenon and identifies the significant and critical variables contributing to adoption breakdown, by analyzing all the case files on failed adoption between 1998 and 2014: 1883 documents, corresponding to a total of 74 children and 62 families.
The Gendered Impacts of Income Fluctuations on Household Departure, Labor Supply, and Human Capital Decisions: Evidence from Kyrgyzstan

How do fluctuations in income affect labor supply decisions, and how do their effects differ by gender? This study analyzes data from a thirteen-year rolling panel in Kyrgyzstan spanning 2004–16. It addresses the endogeneity of fluctuations in income to labor supply decisions by employing shift share instruments that exploit region-level changes over time in growth rates of different sources of revenue and production costs. Estimating a household fixed effects model, the study finds that reductions in income relative to the median spur departure from the household (for example, due to migration), with smaller impacts on women than men. However, women’s labor supply at the origin is affected significantly more, with short-term increases in hours of employment and declines in home production and other activities. Reductions in income also fuel temporary migration for both genders, with larger effects for men, and widen the gender gap in pursuit of non-compulsory education. HIGHLIGHTS Declines in income spur household departure, with larger impacts on men than women. Women are not always “left behind” following shocks; like men, they respond through changes in labor supply and livelihood decisions. At the origin, women face significantly greater increases in workloads than do men. Declines in income widen the gender gap in pursuit of non-compulsory education, favoring men. Policies that support women’s ability to control income can promote domestic work sharing and ensure income generation empowers women.
Determinants of Carbon Emission Disclosure: An Empirical Study on Indonesian Manufacturing Companies

Due to the worsening environmental issues e.g, climate change, the stakeholders impose greater demand and pressure more towards the companies of caring about the environment. The emergence of carbon accounting is a supplement to the adoption of Kyoto Protocol. However, the government has not applied carbon accounting to all companies in Indonesia, because of non-explicit laws and low quality of human resources. Various studies have been conducted to find the determinant factors for companies to make carbon emission disclosure. This research aims at examining the influence of type of industry, profitability, company size, environmental performance, and audit firm reputation on the carbon emission disclosure of manufacturing companies listed on the Indonesia Stock Exchange years 2016-2019. It employed a purposive sampling technique and obtained 290 observations and the data were analyzed using Ordinary Least Square. The shows that type of industry, profitability and company size influence carbon emission disclosure. However, this research does not successfully show the influence of environmental performance and reputation of public accountant office on carbon emission disclosure.
In Situ Aerobic Bioremediation of Sediments Polluted with Petroleum Hydrocarbons: A Critical Review

Oil pollution has been a worldwide concern especially in environments where treatment is quite difficult to apply. Marine polluted sediments, in particular, constitute one of the most recalcitrant environments for bioremediation and are often the final repository of petroleum contaminants, as a result of runoff and deposition. Aerobic hydrocarbon degraders present in the sediments are tackling the pollution under oxygen-limited or oxygen-depleted conditions. Research has focused on new ways to enhance bioremediation under anoxic conditions, however aerobic bioremediation is faster, and hence more effort should be made to sustain oxygen concentration levels. In this review, the different bioremediation techniques used for the decontamination of marine sediments are briefly discussed, and focus is primarily given to the different oxygenation methods used for enhancing aerobic bioremediation and the aeration methods that are suitable for in situ application, as well as state of the art technologies that make in situ aeration an appealing approach. Based on the technologies analyzed, suggestions are made for sediment bioremediation techniques in different marine environments.
Outcomes after transcatheter valve-in-valve implantation using a balloon-expandable Edwards Sapien valve in patients with degenerated Freestyle aortic bioprosthesis.

Background Transcatheter aortic valve-in-valve implantation (ViV TAVI) in degenerated Medtronic Freestyle aortic bioprosthesis (FSB) has been reported as being technically challenging. This study sought to evaluate procedural data and outcomes after ViV TAVI using a balloon-expandable Edwards valve in patients with failed FSB. Methods Between August 2014 and December 2020, twenty-seven consecutive patients underwent ViV TAVI for symptomatic FSB failure at our institution using a Sapien XT (n=1) and Sapien 3 (n=26) valve, respectively. Endpoints were defined according to the Valve Academic Research Consortium-2 (VARC-2) criteria and were retrospectively analyzed. Results Mean patient age was 75.7±8.2 years (female n=5, male n=22); Society of Thoracic Surgeons Predicted Risk of Mortality score was 7.3%±6.2%. ViV implantation with correct positioning of the Edwards Sapien valve within the FSB was successful in all cases. Intraprocedural transesophageal echocardiography revealed none/trace paravalvular regurgitation in twenty-five patients (92.6%), mild paravalvular regurgitation was present in two patients (7.4%). Neither of the patients had a mean gradient ≥20.0 mmHg excluding significant patient-prosthesis mismatch. Three early deaths (≤thirty days) occurred resulting in a device success rate of 88.8%. One-year and three-year survival rates for patients alive beyond day thirty after ViV TAVI were 95.8% and 70.0%, respectively. Conclusions ViV TAVI with Edwards Sapien valves lead to acceptable functional results in high-risk patients with degenerated FSB but early complications must be considered particularly during hospital stay.
Estimating the uncertainty of Australian area‐average temperature anomalies

An important metric for communicating the context and impact of climate change is regionally or nationally averaged temperature anomalies. Quantifying the associated uncertainty adds confidence in the reporting of temperature records and trends. For area‐averaged temperature anomalies derived from point‐source observations we model the uncertainty by a three‐step process: (1) observation random error; (2) spatial analysis grid point uncertainty; and (3) area‐average uncertainty. Each step should reflect the method used to calculate the area average. For Australian area‐average temperature anomalies, the observation random error is modelled as the sum of the sampling uncertainty and the uncertainty in the adjustment process. Daily maximum and minimum temperature time series from the 104 non‐urban locations of the Australian Climate Observation Reference Network—Surface Air Temperature (ACORN‐SAT) version 2 dataset for 1981–2010 are used to estimate the sampling uncertainty, based on predicted location pair zero‐distance correlations having values of less than 1.0. ACORN‐SAT version 2 breakpoint information is used to estimate the uncertainty from the selection of reference stations used in the detection and homogenization processes. Monthly area‐average temperature uncertainty is estimated for the 1910–2018 period from Monte Carlo simulations using the observation uncertainty and the available ACORN‐SAT network for each month. The uncertainty in annual area‐average temperature anomalies is then obtained from the monthly uncertainties and inter‐month correlations modelled with a periodic auto‐regressive model. The ±2σ annual mean temperature area‐average uncertainty is ±0.084°C in 2018 and ± 0.176°C in 1910. The larger value in 1910 is primarily due to decreased ACORN‐SAT coverage over areas of inland Australia. The Australian annual mean temperature change and associated uncertainty from ACORN‐SAT version 2 over 1910–2018 is found to be 1.42 ± 0.28°C. This is consistent with global air temperature warming by around 1°C since 1850.
A hospital-based descriptive cross-sectional study in Eastern India to estimate the effect of nitrofurantoin, an age-old therapeutic option, in uncomplicated urinary tract infection

Background: Urinary pathogens develop lesser resistance against Nitrofurantoin than other antimicrobials such as Fluoroquinolones, Cotrimoxazole, and Carbapenems. Aim and Objective: The objective of this study was to estimate the sensitivity pattern of the urinary isolates against Nitrofurantoin in uncomplicated Urinary tract infection (UTI). Materials and Methods: The descriptive cross-sectional study was performed from January 1, 2020, to June 30, 2020, with 759 cases with signs and symptoms of uncomplicated UTI. Aseptically collected midstream urine was inoculated on Nutrient Agar Media, MacConkeys Agar media, and Blood Agar media for bacterial isolation. Antimicrobial susceptibility testing was done by disk diffusion technique on Mueller Hinton Agar (Kirby Bauer technique) as per Clinical Laboratory Standards Institute guidelines. Results: Out of total of 759 urine samples, in 165 cases bacterial pathogens were isolated (21.73%). Only 17 were resistant to Nitrofurantoin (10.30%) whereas resistance to Fluoroquinolone (Ciprofloxacin) was in 58 isolates (35.15%) and Cotrimoxazole, in 37 isolates (22.42%). Resistance against Carbapenem antibiotics (Imipenem and Meropenem) was found in 29 isolates (17.57%). All the Nitrofurantoin resistant isolates were Gram-negative. Majority of the Nitrofurantoin resistant isolates were Klebsiella pneumonia (8 out of 17, i.e, 47.05%). All Nitrofurantoin resistant isolates were sensitive to Colistin and Tigecycline. Five out of 17 Nitrofurantoin resistant isolates were sensitive to Meropenem and Imipenem (29.41%). The Fischer exact test reveals that Nitrofurantoin is effective against the isolates resistant to Fluoroquinolones, Cotrimoxazole, and Carbapenems. Conclusion: Nitrofurantoin, even today, remains a good choice for empirical therapy for uncomplicated UTI.
“I know a guy”: Examining homeless income generation and spatial mobility

This study explores the variety of income generating activities, along with corresponding distances that homeless and marginally housed persons travel to engage in the activities. Altogether 24 individuals are interviewed, and ethnographic field observations occur over several months to increase rapport. The qualitatively gathered data were used in ArcGIS to calculate travel distances. These income generating activities that persons engaged in were commonly forms of shadow work; the varied types of income generating activities and corresponding mobility considerations are discussed.
Seasonality of DOC Export From a Russian Subarctic Catchment Underlain by Discontinuous Permafrost, Highlighted by High‐Frequency Monitoring

Intense climate change and permafrost degradation impact northern watersheds and ultimately organic carbon transfer from terrestrial to aquatic ecosystems. We investigated the contemporary dissolved organic carbon (DOC) dynamics in a northern catchment underlain by discontinuous permafrost (Graviyka River, northern Siberia), where historical meteorological and hydrological data are available since 1936. Mean annual air temperature (MAAT), in contrast to precipitation and discharge was found to show a significant increasing trend since 1950. Using in situ sensing of fluorescent dissolved organic matter (fDOM), we estimated DOC concentrations at a high temporal frequency (1h) during 3 years (2015–2018), and calculated annual specific fluxes of 5.2–5.5 g C m2 yr−1. High DOC concentrations (above 10 mg L−1) are sustained all year, exhibiting nearly chemostatic behavior. Nevertheless, the high‐frequency survey of DOC and other water parameters revealed the seasonality of DOC origin and pathways in the watershed. The spring freshet dominates the annual export (up to 80%), but summer and autumn floods can also contribute up to 9% and 8% respectively. The high‐frequency sampling was able to capture the specific dynamic of DOC concentration during spring flood (DOC peak preceding discharge, dilution during the spring freshet) and summer and autumn floods (contribution of DOC‐rich, low conductivity water). These observations suggest a significant contribution of organic‐rich water originating in peatlands, potentially from degrading palsas. The study demonstrates both that high‐frequency sampling is essential to capture key events for DOC export, and that more long‐term monitoring is urgently needed in these rapidly evolving watersheds.
