Suicidality and COVID-19: Suicidal ideation, suicidal behaviors and completed suicides amidst the COVID-19 pandemic (Review)

Since the outbreak of the coronavirus 2019 (COVID-19) pandemic, there has been widespread concern that social isolation, financial stress, depression, limited or variable access to health care services and other pandemic-related stressors may contribute to an increase in suicidal behaviors. In patients who have recovered from COVID-19, an increased risk of developing suicidal behaviors may be noted, while post-COVID syndrome comprises another potential risk factor contributing to increased suicidal behaviors. Despite the initial alarming predictions for an increase in suicide rates due to the COVID-19 pandemic, the majority of published studies to date suggest that experienced difficulties and distress do not inevitably translate into an increased number of suicide-related deaths, at least not in the short-term. Nevertheless, the long-term mental health effects of the COVID-19 pandemic have yet to be unfolded and are likely to remain for a long period of time. Suicide prevention and measures aiming at promoting well-being and mitigating the effects of COVID-19 on mental health, particularly among vulnerable groups, should thus be a priority for healthcare professionals and policymakers amidst the evolving COVID-19 pandemic.
Resilient and Accelerated Scale-Up of Subcutaneously Administered Depot–Medroxyprogesterone Acetate in Nigeria (RASuDiN): A Mid-Line Study in COVID-19 Era

Background Injectable contraceptives are fast becoming the method of choice among women in sub-Saharan Africa (SSA). Specifically, the subcutaneously administered depot–medroxyprogesterone acetate (DMPA-SC) is gaining traction as a convenient, private and effective method to address unmet need for family planning (FP). The objective of this study was to determine the trend in DMPA-SC use in Nigeria. Methods Data was extracted from the National Health Management Information System (NHMIS) FP register on DMPA-SC uptake in public health facilities and through community-oriented resource providers (CORPS) in 10 Nigerian states. The linear trend model was adopted in data analysis based on lowest measure of dispersion and/or highest adjusted coefficient of determination (R2). The statistical significance was determined at 5%. Results There was an upward trend in the use of DMPA-SC among clients who received the service through health providers, CORPS and self-injection in the 10 project states over a period of 12 months (August 2019–July 2020). In addition, the linear trend model showed that for every unit increase in months, the average number of women expected to use DMPA-SC through health providers, CORPS and self-injection will increase by 1308.3 (Yt = 3799.7 +1308.3*t), 756.73 (Yt = −1030.8 +756.73*t) and 77.864 (Yt = −159.7 +77.864*t) respectively. In all models, the adjusted coefficient of determination was 99.9% which showed good model fitness. The results also showed that the number of DMPA-SC clients varied across the project states with Niger (32,988) and Oyo (31,511) states reporting the highest number of clients over the period of 12 months. Conclusion There was an increasing use of DMPA-SC and self–injection among clients over time. Health facility and community-based FP programs should be strengthened to ensure improved access to FP services.
Quantitative Analysis of Farmers Perception of the Constraints to Sunflower Production: A Transverse Study Approach Using Hierarchical Logistic Model (HLM)

Sunflower production is an excellent choice for both local and national agribusiness with significant potential in smallholder farming systems due to low input costs, consistent yields, and a short planting window. However, farmers are faced with interrelated constraints in their sunflower production. This study was undertaken to examines the perceptions of the constraints to sunflower production as perceived by smallholder farmers in North West Province, South Africa. The research identifies some factors related to sunflower production constraints. Then, a stratified random sampling technique was used to select 172 sunflower farmers and they were asked to rate their response on these attributes on a 5-points Likert scale. Leveraging principal component analysis (PCA), we agglomerated and condense information from the original datasets of the constraint attributes into three main components (innovation, farm finance, and crop management practice). Because of the hierarchical structure of the dataset with farmers nested within their local municipalities, we use Hierarchical Logistic Modeling techniques to identify the factors that determine farmer’s perceived interest in innovation, farm finance, and crop management practices. Innovation and farm finance emerge to be critical elements for sustainable sunflower production. The findings indicate that age, education, household size, farm size, cooperative membership, and gender are strongly correlated with farmers’ perceived interest in innovation and farm finance characteristics. This study recommends that to promote these elements among smallholder farmers, it is necessary for governments at the local and national level to invest in extension service and education, cooperative organizations, research, and development in disentangling the age, gender, and farm size inequalities existing in the district sunflower production.

This article seeks to examine the role of life course in understanding job quality. It uses a qualitative case study analysis of Australian restaurants and reveals how chefs at different life stages can subjectively perceive the same objective job characteristics differently. The findings extend pre-existing knowledge by demonstrating how workers’ subjective perceptions of job quality are shaped by their life stages.
Evaluating the resilience of a full-scale down-flow hanging sponge reactor to shock-loadings

The effect of shock-loading on the performance of a full-scale down-flow hanging sponge (DHS), used to treat effluent from an up-flow anaerobic sludge blanket treating municipal sewage, was evaluated. This full-scale DHS reactor comprises a polyurethane sponge that retains the sludge. It has a capacity of 500 m3/day and, at the time of this study, had been operating at a sewage treatment plant in India for more than 1,300 days. The DHS reactor was exposed to shock-loadings of organics at double the normal rate for 400 min under summer and winter conditions. The results showed that the DHS reactor maintained stable operation under the organic shock-loading and that it returned to a steady state soon after restart, confirming that the reactor was resilient to organic shock-loadings.
Development of a new respiration rate monitor for cattle.

Studies were conducted investigating bioenergetic responses of growing cattle to heat challenges using respiration rate as one of the primary measures. Respiration rate (RR) was measured using monitors designed from commercially available thin-film pressure sensors and a small battery powered micro-computer. The monitors were designed, fabricated, and tested to provide continuous records as a basis for evaluating stress responses associated with environmental conditions. This article provides details about the monitors and the suitability of obtained records as an indicator of stress, based on measures obtained in environmental chambers during constant and simulated heat wave conditions as well as a field study. Representative data from two laboratory studies indicated an association of RR and ambient temperature (P < 0.01) with diurnal changes being evident in the cyclic test and step changes being evident in the constant ambient temperature tests. A two to three breaths per minute (BPM) rate of change of RR with respect to ambient temperature (°C) was observed for steers in the laboratory studies. The field study revealed a striking response of RR to the ambient temperature (6.6 BPM/°C rate of change) for a steer that had direct solar load (no-shade) compared to a 1.6 BPM/°C rate of change in the shade.
Utilization of Banana Peel Flour in Biscuit Making as Wheat Flour Substitute

The production of biscuits utilizing ripe banana peel flour (BPF) as a wheat flour (WF) alternative is presented in this study. Locally available Sabri banana peel was dried into a cabinet dryer at 65⁰C for 8 hours. The dried peel then turned into powder and sieved. The flours used in the preparation of the biscuits were analyzed for proximate composition. BPF contained a higher amount of fat compared to WF. Five samples of biscuits S1, S2, S3, S4, and S5 substituting WF with 0, 5, 10, 20, and 30% BPF in the standard biscuits were prepared S1 denoted the control sample adding no BPF. The proximate composition and sensory quality of the produced biscuits were tested. All of the biscuit samples had greater weights than the control biscuit. In comparison to the control biscuit, BPF enriched biscuits had reduced diameter. Biscuits made with 10% BPF had a greater spread ratio than those made with other ingredients. The moisture, protein, fat, and total sugar content of biscuit samples were found in the range of 4.05-5.32%, 6.60-9.00%, 10.00-10.32%, and 17.00-25.00%, respectively. A sharp decrease in protein content was observed with the increase of BPF in the biscuits. A slight increase of fat was observed in the BPF substituted biscuits. The ash content in the control sample was 1.5%, and that in the banana peel substituted samples ranged from 1.80% to 2.0%. BPF substitution showed a downward trend in terms of color, flavor, texture, and general acceptability. The panelists rated sample S1 as having the highest overall acceptability. Among the BPF-containing biscuits, sample S2 had the best overall acceptance, followed by samples S3, S4, and S5. In terms of general acceptability, however, there are no notable variations between samples S2 and S3. According to sensory analysis, quality BPF biscuits may be prepared by replacing up to 10% of the WF with BPF.

Approximate average bit error probability for DQPSK over fading channels

The bit error probability (BEP) of DQPSK with Gray coding over an AWGN channel can be computed simply, although it is hard to integrate and derive the average BEP for fading channels. Presented are novel approximations of the average BEP of DQPSK with Gray coding over fading channels. Numerical results show that the novel formulations are quite accurate.
Predatory Journals: How Far Can They Go? An In-Depth Look at the Outliers = Grabežljivi časopisi: koliko daleko mogu ići? Temeljita analiza vrijednosti

For over a decade, predatory publishers, journals and conferences have continuously menaced the research community, preying on its resources, and diminishing the general trust in science, becoming an important research topic. Previous studies have focused on identifying their characteristics, in order to increase the academic awareness and help researchers not becoming a prey. At the same time, predatory publishers diversified their strategies; the academic community developed disparate reactions, which determined more and diverse predatory strategies, aimed at luring and deceiving the scientists. While the process is still ongoing, the present research is aimed at exposing the most extreme predation strategies, in an effort to make the line separating honest and predatory journals more traceable. The analysis of relevant samples focuses on the language issue, based on the hypothesis according to which the predatory publishers are located in countries where English is rarely spoken. The findings, including inventing English names, advertisements making no sense for the Western world, lack of quality control and a poor graphic language, confirm the hypothesis, and are also able to stand at the core of possible guidelines for exposing predatory publishers based on specific features of their calls. = Više od deset godina, grabežljivi izdavači, časopisi i konferencije kontinuirano su ugrožavali istraživačku zajednicu, loveći njene resurse i umanjujući opće povjerenje u nauku, postajući važna istraživačka tema. Prethodne studije bile su usredotočene na identificiranje njihovih karakteristika, kako bi se povećala akademska svijest i pomoglo istraživačima da ne postanu plijen. Istodobno, grabežljivi izdavači diverzificirali su svoje strategije; akademska zajednica razvila je različite reakcije, koje su odredile više i raznovrsnije predatorske strategije, usmjerene na mamljenje i obmanjivanje naučnika. Iako je postupak još uvijek u toku, ovo je istraživanje usmjereno na izlaganje najekstremnijih strategija grabežljivosti, nastojeći da linija koja razdvaja poštene i grabežljive časopise postane sljedivija. Analiza relevantnih studija slučaja usredotočena je na jezičko pitanje, zasnovano na hipotezi prema kojoj se izdavači nalaze u zemljama u kojima se engleski jezik rijetko govori. Nalazi, uključujući izmišljanje engleskih imena, reklame koje nemaju smisla za zapadni svijet, nedostatak kontrole kvaliteta i loš grafički jezik, potvrđuju hipotezu i takođe mogu stajati u srži mogućih smjernica za izlaganje predatorskih izdavača na osnovu specifičnih karakteristika njihovih poziva.
Using Interactive Lecture Demonstrations to Improve Conceptual Understanding of Resonance in an Electronics Course

Abstract Engaging students in a large class environment is difficult. A “blended learning” strategy, which incorporates both traditional lecture instruction followed by active learning instruction, can help. Active learning in this study consisted of a small number of interactive lecture demonstrations (ILDs) that incorporated a “predict, observe, discuss, synthesise” learning cycle. This blended learning strategy was more effective than traditional lectures alone in overcoming students’ conceptual difficulties. The learning gains in this study were assessed by testing the conceptual understanding of students after 8 hours of traditional instruction, but before any ILD instruction (via a pre-test) and after an additional 2 hours of ILD instruction (via a post-test). The average gain in the post-test score compared to the pre-test score for “complete responders” (ie. the students who participated in all tests and all active learning ILD activities) was very encouraging and statistically significant.
Three-dimensional random stacking of weakly heterogeneous palletization with demand requirements and stability measures

Random stacking is a complex procedure by which boxes are loaded in undefined patterns. The proposed model is a modification to a recent heuristic that has been developed to comply with weakly heterogeneous palletization of boxes arriving in random order. Modifications were made in such pallet load stability, and box demand requirements are incorporated. The different palletization procedures of the heuristic have been simulated using TURBO C++ programs. Ten different simulation runs were conducted to validate the modified heuristic. The results are compared with those of the previous model.
The selective dynamical downscaling method for extreme‐wind atlases

A selective dynamical downscaling method is developed to obtain extreme-wind atlases for large areas. The method is general, efficient and flexible. The method consists of three steps: (i) identifying storm episodes for a particular area, (ii) downscaling of the storms using mesoscale modelling and (iii) post-processing. The post-processing generalizes the winds from the mesoscale modelling to standard conditions, i.e. 10-m height over a homogeneous surface with roughness length of 5 cm. The generalized winds are then used to calculate the 50-year wind using the annual maximum method for each mesoscale grid point. The generalization of the mesoscale winds through the post-processing provides a framework for data validation and for applying further the mesoscale extreme winds at specific places using microscale modelling. The results are compared with measurements from two areas with different types of extreme-wind climates, and the results are promising. Copyright © 2012 John Wiley & Sons, Ltd.
TRAINING NEEDS OF VEGETABLE GROWERS REGARDING PEST MANAGEMENT FOR SUSTAINABLE ENVIRONMENT HEALTH IN THE PUNJAB, PAKISTAN

Vegetables are very important crop and are vulnerable to a number of overwhelming pests. Pesticides are considered a vital component of modern farming and playing a major role for the control of pests in maintaining high agricultural productivity. Pesticides sprayed on vegetables do not stay on the targeted area. Pesticides are toxin. However, concerns about human health and environmental effects of pesticides have increased over the past several years. High number of human’s pesticides poisoning are happening in Pakistan. Effective use of pesticide is generally influenced by knowledge possessed by the vegetable growers. The study was conducted to evaluate the knowledge level of vegetable growers and determining their training needs regarding safe pest management in two potato growing districts of Punjab. The data were collected from randomly selected 367 vegetable growers proportionately chosen from randomly selected two tehsils of the selected districts. This study concludes that the growers need training for pest management on priority basis regarding the areas; pest identification (mean = 1.45); pest control (mean = 1.46); and pesticides (mean =1.59) respectively.
Surveillance and Control of Tunnel Traffic by an On-Line Digital Computer

An experimental surveillance and control system was in operation for one lane of the Lincoln Tunnel in New York City, during most of the year 1967. The system shared in the use of an IBM 7040 computer located at the IBM Research Center, forty miles away from the tunnel. The computer received via a telephone line signals from pairs of detectors located at four observation points along the tunnel. From these signals were determined the number of vehicles in the three sections of the tunnel between the four observation points, as well as the speed and throughput over these four points. The control system reduced the input of traffic into the tunnel when needed in order to prevent congestion, which has been known to reduce appreciably the throughput of the tunnel. It has been shown that knowledge of the exact number of vehicles in the three sections of the tunnel permits much more timely action than has been possible in the past, resulting in longer periods of sustained high flow at comfortable speeds.

The nature of inpatient rehabilitation for people with aphasia from culturally and linguistically diverse backgrounds: a scoping review

ABSTRACT Background Due to language and cultural barriers, people with aphasia from culturally and linguistically diverse (CALD) backgrounds are at risk of disadvantage in their access to comprehensive care. They are at higher risk of poorer inpatient outcomes in addition to challenges in receiving appropriate aphasia assessment and intervention. Objectives This study aims to examine the extent and nature of what is known about the inpatient phase of aphasia rehabilitation for CALD stroke survivors and identify potential research gaps in the literature for investigation. Methods A scoping review with systematic search was conducted in September 2020 following the PRISMA Scoping Review checklist. Five electronic databases were searched using a combination of terms pertaining to “aphasia,” “inpatient care” and “CALD. ” Key variables were extracted from studies that met the inclusion criteria for analysis. Results Eighteen studies were yielded. Data regarding the inpatient phase of care indicate that CALD people with aphasia do not always receive comprehensive assessment or intervention in all their languages that may impact their discharge destination and access to community services. Speech-language pathologists (SLPs) report numerous barriers to service provision for this population. No studies investigated the degree and nature of differences in outcomes between CALD and non-CALD stroke survivors with aphasia. Conclusions CALD stroke survivors with aphasia inconsistently access SLP services in hospital. Assessment is unlikely to be conducted in patient primary languages and therapy is usually provided in the language of SLPs. Further research is required to determine whether this impacts functional outcomes and health services.
Modeling of the static and dynamic responses of an integrated laser Mac-Zehnder modulator and comparison with an integrated laser EA modulator

In an integrated laser Mach-Zehnder modulator (ILMZ), as well as in an integrated laser electroabsorption (EA) modulator (ILM), optical feedback can lead to a high level of frequency chirp and relaxation oscillations, compared to the case of a laser coupled into a discrete external modulator through an optical isolator. To investigate these aspects, in the particular case of the ILMZ, an original model has been developed. Analytical expressions of the frequency modulation (FM) and amplitude modulation (AM) responses of two types (2/spl times/1 and 2/spl times/2 output couplers) of ILMZ are given by the model, and the direct and indirect contributions to the FM responses are identified. The model can be used in the design and optimization of the ILMS, aiming at a small optical frequency chirp and small AM perturbation at resonance frequency. Numerical simulation of the small signal response (AM and FM modulations) has been performed for both ILMZ configurations and an ILM. A lower chirp is obtained for the ILMZ compared to the ILM. A high extinction ratio and a low negative effective chirp parameter are predicted at output B of the 2/spl times/2 ILMZ, as well as for the /spl pi/-phase-shifted 2/spl times/1 ILMZ.
Prediction of Pb (II) and Cu (II) Ions Biosorption by Annona muricata L. Seeds Using Artificial Neural Network (ANN) Approach

A model of biosorption based on a three-layers structure of Artificial Neural Network (ANN) was developed to predict the efficiency of removing Pb(II) and Cu(II) ions from aqueous solutions using Annona muricata L. seed. Data obtained from the experimental conditions was applied using the back propagation learning algorithm with one input layer contains two neurons, one hidden layer which contains nine neurons, 15 neurons biased and one output layer contains one neuron (2-9-1 structure) to predict the artificial neural network approach of the biosorption process. Experimental data set used as the input training data on ANN. For each set of experimental data, the model will issue 100 data ANN prediction, where 5% to 10% were cross-validated with experimental data. Linear regression between the network outputs and the corresponding targets proved satisfactory with the minimum mean squared error (MSE) approximately 0.0012 and average correlation coefficient of about 0.9985 to seven sets of experimental data. Modified Freundlich and Langmuir models is also made of the 100 ANN’s output data (called Langmuir-ANN and Freundlich-ANN) and displayed along with experimental data.
