Morbidity and mortality among health care workers due to coronavirus disease 2019

Background: A novel coronavirus disease started in Wuhan, China, in December 2019. With its rapid spread, many cases were reported from other countries resulting in more than 2 million confirmed cases of coronavirus disease 2019 (COVID-19) worldwide. Health care workers (HCWs) are the frontline warriors of any outbreak response and as such are exposed to hazards that put them at risk of infections, here with the coronavirus. Aim and Objective: Incidences of morbidity and mortality among HCWs have also been reported in many countries. Despite these isolated reports, a comparative data among the majorly affected countries were not available. In this article, an attempt has been made to review the effect of COVID-19 on the health of the HCWs. Materials and Methods: This is an observational study where data regarding morbidity and mortality among HCWs were collected by online search until April 30, 2020. Data were collected from the World Health Organization website and government and health-care websites. Various online newspaper articles were also checked and relevant information was collected. To evaluate and analyze, a data collection sheet was prepared. Results: In our study, the number of affected HCWs was highest in Spain, followed by Italy, the United States of America, China, and the UK. Till April 2020, the total number of affected HCWs in India although very less, the correlation between infection and death in HCWs due to COVID-19 was found statistically significant. Conclusion: The HCWs being the frontline warriors in the fight against COVID-19, they should be provided with adequate protective measures to minimize morbidity and mortality in them.
Reaching for Yield in the Going-Public Market: Evidence from SPACs

This paper provides a unified explanation for the existence, time-series variation, and recent boom of the Special Purpose Acquisition Company (SPAC). We develop a theoretical framework in which SPAC and IPO markets serve different types of production firms and public investors. SPAC managers act as non-bank certification intermediaries and match yield-seeking investors with value-creating but risky production firms. Reaching for yield in the going-public market contributes to the rise of SPACs. Our model jointly explains several empirical patterns regarding the U.S. SPAC market: (1) Compared to IPO firms, SPAC firms are ex-ante smaller, riskier, but grow at higher or similar rates after going public. (2) SPAC issuance boomed in 2007 prior to the Global Financial Crisis and accelerated from 2015 to 2020. (3) The market share of SPACs is strongly positively correlated with equity market sentiment. Finally, given these findings, we discuss the importance of aligning sponsors with long-term investors and provide recommendations for an improved SPAC structure.
Improvement in growth performance of broiler chicken on dietary supplementation of mushroom powder (Agaricus bisporus) and probiotics (Saccharomyces cerevisiae)

A study was conducted to evaluate the effect of mushroom (Agaricus bisporus) and probiotics (Saccharomyces cerevisiae) on broiler performance. Day-old broiler chicks (n=360) of strain (Cobb 400) were divided randomly into eight groups. Each represented a treatment (45 birds/ treatment) with triplicate in a completely randomized design. The experimental diets were designed as, T1: control, T2: 0.4% mushroom powder, T3: 0.8% mushroom powder, T4: 1.2% mushroom powder, T5: 0.1% probiotics, T6: 0.2% probiotics, T7: 0.3% probiotics and T8: 0.8% mushroom powder + 0.2% probiotics levels. The results showed that the average body weight was significantly higher in (T4) group compare to control diet. The highest gain in the body weight was observed in the probiotics supplemented group (T5) and the lowest mean body weight gain was recorded in (T7) group. The lowest feed consumption was noticed in the control group (T1) which was appreciably (P

Living Labs: From Niche to Mainstream Innovation Management

Living Labs have received increasing attention over the last decade. However, despite their growing popularity and ability to positively impact organisations’ innovation performance, mainstream innovation management literature has overlooked the diverse and promising Living Labs research landscape. In an effort to move the field forward, this study analyses extant Living Labs literature in the domain of innovation management. The study identifies conceptual bases informing Living Labs research, maps the collaboration between scholars in the field, examines prevailing themes influencing the debate and reveals the influence of Living Labs research on other domains. Bibliometric methods of co-authorship, keyword co-occurrence analysis as well as bibliographic coupling are employed on two databases. Database A includes 97 focal journal articles and Database B includes all cited sources of Database A, totalling 500 documents. This study reveals the rapid growth of the scholarly literature on Living Labs in the innovation management domain, driven by a core group of authors. However, other contributions from highly visible scholars have the potential to connect Living Lab research to mainstream innovation management studies. The study also identifies the influence of Living Labs research in different application fields and potential for its further evolution.
Study of effects of repeated administration and withdrawal of cannabinoids on brain tissue of adult male albino rats: histopathological and biochemical study

Introduction: Cannabis occupies the position of the most prevalent drug of abuse in Egypt. Chronic cannabis abuse may cause degenerative pathological changes in the brain, also the effect of cannabis on cognition, memory and learning is well known. The current work aimed to study the toxic effect of chronic repeated doses of cannabis on rat behavior, brain dopamine level and histopathological changes of the brain. Subjects and Methods: The study was conducted on 50 male albino rats weighing 180-200 gm. Rats were divided into 2 main groups: group 1 (control; each animal received 1ml/day 100% sunflower oil (used as a vehicle); group 2 (received cannabis daily for one month "40 mg cannabis/ 200 gm rat". At the end of the month this group was subdivided into 4 subgroups: subgroups 2a, 2b, 2c, and 2d and subjected to different periods of cannabis abstinence. The clinical manifestations due to the effect of long-term cannabis administration and withdrawal were recorded. After scarification, brain dopamine level was measured, and brain tissue was examined by light and electron microscope (EM). Results: Clinically; main manifestations of long-term cannabis administration found in subgroup 2a were CNS depression; while main manifestations in subgroup 2c were irritability and fighting aggression. Dopamine significantly increased in subgroup 2a compared to control group. Light and EM examination showed degenerative changes. Conclusion: Brain dopamine level was significantly high in subgroup 2a compared with control group. long-term cannabis administration causes degenerative pathological changes in the brain, which need long recovery periods.
Electrically tunable, plasmon resonance enhanced, terahertz third harmonic generation via graphene

In this study, we demonstrate how field enhancement due to plasmonic resonances can noticeably improve the efficiency of third harmonic generation (THG) from graphene sheets on a grating substrate under normal illumination of terahertz (THz) waves. We explore how different parameters of graphene and the substrate can affect the strength of the resonance and, thus, the third harmonic (TH) level. Interestingly, we show that the gate voltage tunability of the linear and nonlinear conductivities of graphene and, thus, the resonant frequency of the structure, enable the achievement and control of the plasmonic resonance enhanced THG over the THz frequency band. Based on our finite difference time domain (FDTD) numerical simulations, we reveal that a more than 5 orders of magnitude improvement in the TH level would be achievable by placing high quality graphene samples on a grating substrate under resonant conditions instead of placing them on a flat substrate. We hope that these findings can pave the way for the development of a plethora of valuable applications in the THz frequency band, such as generating new frequencies, spectroscopy, and signal processing.
Carbohydrates and Forage Quality

Carbohydrates are the most abundant class of compounds found in plants. They account for 50-80% of the dry biomass of forage species (Van Soest, 1982). From a plant perspective, carbohydrates play important roles in intermediary metabolism, energy transfer and storage, and plant structure. Photosynthetic energy is fixed in carbohydrates via the Calvin cycle and these carbohydrates serve as initial substrates for nearly all intermediary pathways in plants. Energy is translocated within plants as the disaccharide sucrose (Hawker, 1985), and stored in polymers such as starch and fructans (Manners, 1985; Pontis and Del Campillo, 1985). Carbohydrates constitute most of the plant cell wall and therefore play an important role in the structural integrity of individual cells, tissues, and organs (Hatfield, 1989). Carbohydrates are extremely important from a nutritional perspective, providing the primary source of energy in ruminant diets. In ruminants, nearly all carbohydrate digestion (> 90 %) occurs within the rumen (Armstrong and Smithard, 1979; Sutton, 1979), although under certain circumstances, such as high rates of passage, a significant amount of carbohydrate digestion can occur in the small and large intestines (Hoover, 1978; Nocek and Tamminga, 1991). Simple sugars are rapidly fermented within the rumen to yield volatile fatty acids which are absorbed into the blood through the rumen wall (Morrison, 1979; Baldwin and Allison, 1983). Polysaccharides must be degraded to simple sugars before being utilized. Nonstructural polysaccharides, such as starch and fructans, are rapidly and generally completely degraded within the rumen (Nocek and Tamminga, 1991), while degradability of structural polysaccharides varies considerably. Pectins are rapidly and essentially completely degraded by ruminal microbes (Hatfield, 1989, 1993a). Cellulose and hemicellulosic polysaccharides are more slowly and incompletely degraded. Cellulose degradability of forages varies from 25-90% while hemicellulose digestibility varies from 45-90% (Pigden and Heaney, 1969). Degradation of {3-glucans is intermediate to that of pectins and cellulose (Van Soest et aI., 1991). This ability to degrade and utilize structural carbohydrates confers upon ruminants their unique ecological niche (Chesson and Forsberg, 1988).
Efficacy of Bifidobacterium bifidum G9-1 in improving quality of life in patients with chronic constipation: a prospective intervention study

Chronic constipation is a functional disorder that decreases a patient’s quality of life (QOL). Because dysbiosis has been associated with constipation, we aimed to investigate the efficacy of Bifidobacterium bifidum G9-1 (BBG9-1) in improving QOL in patients with constipation. This was a prospective, single-center, non-blinded, single-arm feasibility trial. A total of 31 patients with constipation and decreased QOL received BBG9-1 treatment for 8 weeks, followed by a 2-week washout period. The primary endpoint was change in the overall Japanese version of the patient assessment of constipation of QOL (JPAC-QOL) score after probiotic administration relative to that at baseline. Secondary endpoints included changes in gut microbiota, stool consistency, frequency of bowel movement, degree of straining, sensation of incomplete evacuation, and frequency of rescue drug use. The overall JPAC-QOL scores and frequency of bowel movement significantly improved after BBG9-1 administration from those at baseline (p<0.01 and p<0.01, respectively). There were no statistically significant changes in other clinical symptoms. Subset analysis revealed that patients with initial Bristol Stool Form Scale stool types of <4 had improvements in stool consistency, a significant increase in the frequency of bowel movements, and a significant alleviation in the degree of straining, following BBG9-1 administration. At the genus and species levels, Sarcina and Sarcina maxima were significantly increased. Functional analysis showed that butanoate metabolism increased significantly, whereas methane metabolism decreased significantly. We concluded that BBG9-1 is safe and improves QOL in patients with constipation. The underlying improvements may be due to changes in stool consistency.

The Impact of Photo Overlap, the Number of Control Points and the Method of Camera Calibration on the Accuracy of 3D Model Reconstruction

This research attempted to determine the optimal photo overlap, number of con‐ trol points and method of camera calibration for a photogrammetric 3D model reconstruction of an object of cultural heritage value. Terrestrial images of the object were taken with a hand‐held digital camera and processed in the Con‐ textCapture software using the Structure‐from‐Motion (SfM) algorithm. A total station was used to measure ground control points (GCPs) and check points. Here, the research workflow, methodology, and various analyses concerning different configurations of the aforementioned factors are described. An at‐ tempt to assess the parameters which should be implemented in order to pro‐ vide a high degree of accuracy of the model and reduce time‐consumption both during fieldwork and data processing was taken. The manuscript discusses the results of the analyses and compares them with other studies presented by dif‐ ferent authors and indicates further potential directions of studies within this scope. Based on the authors’ experience with this research, some general con‐ clusions and remarks concerning the planning of photo acquisition from the terrestrial level for the purpose of 3D model reconstruction were formulated.
Refraining from seeking mental healthcare and poorer mental well-being: A longitudinal population-based study on men in Sweden

Background: Depression and anxiety disorder contribute to a significant part of the disease burden among men, yet many men refrain from seeking care or receive insufficient care when they do seek it. This is plausibly detrimental to men’s mental well-being, but there is a lack of population-based research to confirm this. This study investigated 1) if men who had refrained from seeking mental healthcare had poorer mental well-being than those who sought care, 2) if those who sought care but perceived it as insufficient had poorer mental well-being than those who perceived care as sufficient, and 3) if these differences persisted after one year. Methods: This longitudinal study used questionnaire data from a population-based sample of 1240 men, aged 19-64 years, in Sweden. Having refrained from seeking mental healthcare, or perceiving the care as insufficient, at any time in life, was assessed in a questionnaire, 2008. Current mental well-being was assessed in 2008 and 2009 using mean scores on the WHO (Ten) Well-being Index, with a lower score indicating poorer mental well-being. Group differences were calculated using t-tests and multivariable linear regression analysis.Results: Of the men who had perceived a need for mental healthcare, 37% refrained from seeking such care. They had lower mental well-being scores in 2008, compared to those who sought care. Of those seeking care, 29 % perceived it as insufficient. They had lower mental well-being scores in 2008, compared to those who perceived the care as sufficient, but this was not statistically significant when controlling for potential confounders. There were no differences in mental well-being scores based on care-seeking or perceived care-sufficiency in 2009. Conclusions: This population-based study provides some support for the hypothesis that refraining from seeking mental healthcare, or perceiving the care as insufficient, is detrimental to men’s mental well-being. However, the lack of differences over time contradicts this hypothesis. The results highlight the need for larger longitudinal studies, measuring care-seeking within a more specified time frame, and using longer follow-up periods. This should be combined with efforts to increase men’s mental healthcare-seeking and to provide mental healthcare that is perceived as sufficient.
Electrical Measurement of Cell-to-Cell Variation of Critical Charge in SRAM and Sensitivity to Single-Event Upsets by Low-Energy Protons

The distribution of single-event upsets (SEUs) in commercial off-the-shelf (COTS) static random access memory (SRAM) has generally been thought to be uniform in a device. However, process-induced variation within a device gives rise to variation within the cell-level electrical characteristic known as the data retention voltage (<inline-formula> <tex-math notation="LaTeX">$V_{\mathrm{ DR}}$ </tex-math></inline-formula>). Furthermore, <inline-formula> <tex-math notation="LaTeX">$V_{\mathrm{ DR}}$ </tex-math></inline-formula> has been shown to directly influence the critical charge (<inline-formula> <tex-math notation="LaTeX">$Q_{\mathrm{ C}}$ </tex-math></inline-formula>) necessary for stored data to upset. Low-energy proton irradiation of COTS SRAMs exhibits a preference toward upsetting cells with lower <inline-formula> <tex-math notation="LaTeX">$Q_{\mathrm{ C}}$ </tex-math></inline-formula>. An electrical procedure is presented to map relative cell critical charge values without knowledge of the underlying circuitry, allowing customized device usage. Given cell-level <inline-formula> <tex-math notation="LaTeX">$Q_{\mathrm{ C}}$ </tex-math></inline-formula> knowledge, a device can have its cells “screened” such that those with low <inline-formula> <tex-math notation="LaTeX">$Q_{\mathrm{ C}}$ </tex-math></inline-formula> are not used to store data. This work presents the results such a screening process has on the SEU per bit cross section.

Vocabulary Acquisition Through Multimedia In An Iraqi EFL Context

The aim of this study is to investigate the effectiveness of using two types of multimedia techniques (PowerPoint and YouTube videos) on Iraqi EFL learners’ vocabulary acquisition. To achieve the objective of this study, a Non- Randomized pre- post- test control group design has been used. The sample of the study consisted of 75 EFL learners at the intermediate level. The sample is divided into three groups: an experimental group 1 (25) learners, an experimental group 2 (25) learners and a control group (25) learners. The experimental group 1 was taught vocabulary by watching PowerPoint presentations, the experimental group 2 was taught vocabulary by watching YouTube videos, while the control group was taught by using the traditional method of teaching vocabulary. The results revealed that multimedia techniques have a positive influence on enhancing vocabulary acquisition.
