Synthesis and structural properties of clinopyroxenes of the hedenbergite CaFe2+Si2O6 – aegirine NaFe3+Si2O6 solid-solution series

Clinopyroxenes along the solid solution hedenbergite-aegirine M2[Ca2+1-xNa+xM1{Fe2+1-xFe3+x}Si2O6 were synthesized using hydrothermal techniques at 4 kbar. Different temperatures and redox conditions were used to determine optimum synthesis conditions and the stability range of individual compositions in the T - log fO2 field. Synthesized samples were characterized using microprobe analysis, X-ray powder diffraction and Mossbauer spectroscopy at 298 K and 80 K. The structure was refined in the C 2/ c space group by means of the Rietveld method. Along the solid-solution series between hedenbergite (a = 9.8448(6) A, b = 9.0296(6) A, c = 5.2452(4) A, β = 104.813) and aegirine endmembers (a = 9.6547(6) A, b = 8.7941(8) A, c = 5.2944(4) A, β = 107.398), the changes in unit cell dimensions show significant deviations from linearity. Mean and individual M1-O distances decrease linearly from hedenbergite to aegirine; mean M2-O and T-O distances do not change significantly, whereas individual length may vary. While in hedenbergite the coordination of the M2 site is 6+2, it is 4+4 in aegirine. The Mossbauer spectra of the solid-solution endmembers display narrowly split resonance absorption lines with hyperfine parameters typical for Fe2+ (δ = 1.18 mm/s, Δ = 2.25 mm/s at 298 K) and Fe3+ (δ = 0.38 mm/s, Δ = 0.30 mm/s at 298 K). Fe occupies only the M1 site. The Fe2+ resonance absorption is somewhat broadened in the 80 K spectra of the solid solution, which is due to a distribution of quadrupole splittings.
Design of Single Atom Catalysts

ABSTRACT Over the past decade, computational modeling based on density functional theory (DFT) calculations provides a deep insight into the catalytic mechanism of single-atom catalysts (SACs) and paves way for high-throughput screening of promising SACs. This review summarizes computational methods for the analysis of the electronic structures and catalytic performance of SACs, as well as introduces the utilization of descriptors for the computational design of SACs. We expect that future advances in computational methods will surely help to identify highly effective SACs for a wide variety of reactions. Graphical Abstract
Good hygiene practices in school canteens: evaluation between types of schools and administration as well as presence of technical professional

The aim of the study was to evaluate the school canteens located within different types of schools, together with their types of administration and the presence of a technical professional regarding Good Hygiene Practices (GHPs). The observational study was conducted in 111 school canteens, 35 from private and 76 public schools in Curitiba, Brazil. A checklist based on national and international legislation on good hygiene practices -GHP was elaborated and applied during the work routine. With the list, the information was gathered about the type of administration and the presence of a technical professional (nutritionist) in these canteens. Most school canteens were classified as Regular, comprising between 50% and 69% of adequate assessment in relation to GHPs. The most unsatisfactory criteria were related to food temperature control, training of food handlers and Manual of GHPs and Standard Operating Procedures (SOP). Private school canteens were better classified than public school canteens in most of the categories evaluated (p < 0.05). In addition, the school canteens that have been outsourced and have also had a person technically responsible (nutritionist) (p < 0.01) presented the best results. This shows the need for the public school canteens with self-management systems and no technical professional to re-evaluate the sanitary criteria and to implement new strategies, as well as improving procedures for food temperature control, training of food handlers and elaboration of Manual of GHPs and SOP. Improvement with respect to these procedures will Good hygiene practices in school canteens: evaluation between types of schools and administration as well as presence of technical professional Wognski, A.

Availability and affordability of essential medicines and diagnostic tests for diabetes mellitus in sub-Saharan Africa: A systematic review.

Background Currently, sub-Saharan Africa (SSA) is experiencing a steady increase in the prevalence of diabetes mellitus (DM) coupled with a prevailing high burden of communicable diseases. To effectively address this burgeoning burden of DM, optimal access to affordable essential medicines and diagnostic tests for DM in healthcare systems should be prioritised. We conducted a systematic review of the evidence on the availability and affordability of essential medicines and diagnostic tests for DM in SSA as recommended by the World Health Organization Package of Essential Non-communicable Disease Interventions for Primary Health Care in Low-Resource Settings. Methods PubMed, Science Direct and African Journals Online databases were searched for original research articles conducted in sub-Saharan Africa and published between 2000 and 2018 reporting availability and affordability of essential medicines and diagnostic tests for diabetes mellitus. Results Twenty one original cross-sectional studies were included in the systematic review, with the majority conducted in Eastern Africa (n=11, 58%). The availability of essential medicines and diagnostic tests was largely sub-optimal. For oral hypoglycaemic agents and insulin, angiotensin-converting-enzyme inhibitors, statins and aspirin, availability ranged from 0-100%, 0-96.5%, 0-84% and 53%-100% respectively. Considering diagnostic tests, availability of blood glucose tests, urine protein and ketone tests, serum creatinine tests, lipid profile tests and electrocardiography ranged from 6-100%, 33.3-100%, 0-86.4%, 0-65.9% and 5.7-54.6% respectively. The lowest priced generic (LPG) glibenclamide, metformin and aspirin cost <1.2 days’ wages. However, the cost of LPG insulin (any type), captopril and simvastatin ranged from 3.85-18.7 days’ wages, 1.2-6.41 days’ wages and 6.5-30 days’ wages respectively. Blood glucose tests, urine protein and ketone tests and serum creatinine tests cost <3.3 days’ wages. Conclusions Optimal access to affordable essential medicines and diagnostic tests for DM remains a significant challenge in SSA. This represents a significant barrier towards the attainment of sustainable development goals and universal health coverage. Pragmatic region-specific solutions are urgently needed to address this challenge.
Reporting Complex Multidisciplinary Healthcare Team Training Interventions: Development and Validation of a Checklist

Background Multidisciplinary healthcare teamwork training is regarded as a means to improve patient safety and quality of care. However, it is increasingly characterized by highly complex and contextualized interventions, challenging scholars and practitioners in evaluating reports of such interventions effectively. Conflicting or weak evidence as to whether these complex interventions ultimately affect patient outcomes suggests the need for more comparability, reproducibility, and transparency in scientific reporting. In the absence of an existing reporting guideline, we developed a new checklist for effective reports on the planning, content and implementation design and outcomes of complex teamwork training programs.Methods The checklist was developed through pragmatically consulting existing relevant frameworks for evaluating complex interventional studies as well as related key literature on teamwork training. We followed a stepped approach in data retrieval, applying a configurative synthesis. Subsequently, the checklist’s validity and usability were tested based on a literature review of peer-reviewed journal articles describing the implementation of the widely used comprehensive TeamSTEPPS™ curriculum. We used our checklist to evaluate the reporting in the included articles based on specific selection criteria.Results The Reporting Complex Multidisciplinary Healthcare Teamwork Training (ReCoMuTe) checklist presented in this paper exists of four distinct categories, each containing components and various explicating elements: Context and preparation; Description; Execution and delivery; Mechanisms of impact. Despite its wide use across various healthcare institutions and settings and the increasing number of publications on its implementation, we found that the reporting in papers on TeamSTEPPS implementation is often inadequate.Conclusion More standardized scientific reporting on the design and content of complex teamwork training interventions, their contextualized implementation processes and outcomes, can bolster the understanding of effective intervention design, implementation, and evaluation, and can enable well-informed decision making on investments. The ReCoMuTe checklist provides an instrument for evaluating complex interventions, such as studies on TeamSTEPPS implementation, and can assist authors, reviewers, editors, and others in further contemporary research on multidisciplinary healthcare teamwork.
Effects of in ovo Supplementation with Nano-nutrition (L-Arginine Conjugated with Ag NPs) on Muscle Growth, Immune Response and Heat Shock Proteins at Different Chicken Embryonic Development Stages

The aim of the study was to analyze the in ovo injection of chemically and biologically synthesized silver nano-particles (Ag NPs) using Brassica oleracea L. var capitate f. Rubra, (BOL) conjugation with L-Arginine (L-Arg) on the immune, muscle growth, survivability and hatchability of the broiler chickens. L-Arg (100 μg) conjugated with 1000 µg of Ag NPs synthesized by (BOL)-extract and L-Arg (100 μg) conjugated with 100 µg of Ag NPs chemically synthesized were injected into fertile eggs at 8d, 14d and 18d of incubation. Living embryo and hatched chicks were calculated. Survivability and hatchability were not affected by the injected dose of L-Arg (100 μg) with 1000 µg (BOL-Ag NPs) and L-Arg (100 μg) with 100 µg (C-Ag NPs) but it significantly improved when the eggs were injected on day 14 of incubation compared with those injected on days 8 or 18. Moreover, the protein expression of muscle development markers such as myogenin and myoD were significantly up-related in 14 d of incubation whereas the heat shock proteins (HSPs) such as HSP-60 and HSP-70 were significantly up-regulated in 18 d incubation. In addition, the in ovo injection on 18 d significantly increased the serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) as well the immunoglobulin (IgM) levels were increased in 14d incubation period in serum at the same concentration.
Gender differences in income distributions in Poland

The paper presents results of a descriptive analysis of income distributions as well as top income inequality among women and men in Poland. The analysis is based on the dataset provided by the Council for Social Monitoring (2019). Throughout 2003–2015 their panel survey included, for example, a question on individual net monthly income in the past three months. In order to reduce differences associated with the age of entering and exiting the labour market on declared income levels (especially pensions), the calculations include only women and men aged 25–60 years. The analysis of income distributions of women and men in Poland is based on standard measures such as mean income, median income and related measures, as well as the Gini coefficient, Theil index and entropy index. It is supplemented by kernel density estimates and results of simultaneous quantile regressions that demonstrate differences between women and men across income groups. The analysis of top income inequality includes comparisons of subsamples consisting of top 3% earners in each group. The share of women in the top percentiles is then calculated and discussed. The analysis shows different dynamics related to the incomes of women and men, which provides support for including business cycle considerations in the analysis of income inequalities and their gender aspects.
Physical and Biological Treatment Technologies of Slaughterhouse Wastewater: A Review

Physical and biological treatment technology are considered a highly feasible and economic way to treat slaughterhouse wastewater. To achieve the desired effluent quality for disposal or reuse, various technological options were reviewed. However, most practical operations are accompanied by several advantages and disadvantages. Nevertheless, due to the presence of biodegradable organic matter in slaughterhouse waste, anaerobic digestion technology is commonly applied for economic gain. In this paper, the common technologies used for slaughterhouse wastewater treatment and their suitability were reviewed. The advantages and disadvantages of the different processes were evaluated. Physical treatments (dissolved air floatation (DAF), coagulation–flocculation and sedimentation, electrocoagulation process and membrane technology) were found to be more effective but required a large space to operate and intensive capital investment. However, some biological treatments such as anaerobic, facultative lagoons, activated sludge process and trickling filters were also effective but required longer start-up periods. This review further explores the various strategies being used in the treatment of other wastewater for the production of valuable by-products through anaerobic digestion.
Body Mass Index, Eating Habits and Physical Activity Among Dietetics Students in Universiti Sultan Zainal Abidin

University life is a critical period of change in eating habits. Weight gain is a serious problem among youths who are experiencing a change in university life. Universities are potentially important settings for promotion of healthy diet and weight management practice for healthy future. Present study aimed to assess physical activity, eating habits and their association with body mass index (BMI) in dietetics students at Universiti Sultan Zainal Abidin (UniSZA). A total of 126 students were involved in answering a set of survey questions as well as weight and height measurements. Data were analyzed using SPSS version 22.0. Result showed that, 9.5% of dietetics students were obese and 25.4% were overweight. Breakfast was the most frequently skipped meal (71.4%) with the main reason of time management followed by busyness in attending lectures and doing readings. Majority of students (73%) will take a snack when they skipped their meal time. Most of the students consume fruits sometimes (55.6%) and 37.3% of them also consume vegetables sometimes. Most of the students (37.3%) consumes fast food one to three times per month. More than half of the students (59.5%) prefer to eat with friends. Majority of students have moderate physical activity (42.9%). However, this study also did not show association between physical activity, eating habits and BMI. In a nutshell, health programs are necessary to create awareness of nutrition and a healthy lifestyle among youth as the arising of obesity incidence among youth is worrying.
Some Alcohol-Related Consequences for Women May Signal an Escape from Interpersonal Violence

Alcohol-related negative consequences can be very costly and emotionally devastating for those with Alcohol Use Disorder and those around them. Such, consequences include driving under the influence motor vehicle accident fatalities, other accidental deaths, and cirrhosis. We investigate two main queries using the data from Project COMBINE (Anton et al., 2006) to deter-mine which negative consequences are most frequent for women, and to de-termine whether there are differences across ethnicity (for women) on negative consequences. The research method is secondary data analysis. An interpretation of the results turns the typical perspective on its head: We posit that results suggest women are escaping from interpersonal violence, which is of course an excellent outcome.
Quality of bamboo shoots during storage as affected by high hydrostatic pressure processing

ABSTRACT The effect of high hydrostatic pressure (HHP) processing on the quality of bamboo shoots during a storage period of 15 d at room temperature was investigated. The results indicated that when compared to other methods, the bamboo shoots treated at 300 MPa for 10 min displayed the best quality when stored. The weight loss and titratable acidity (TA) in these samples presented a minimal increase at the end of storage, from 0% and 0.1317 g kg−1 to 0.67% and 0.2793 g kg−1, respectively. The respiratory intensity, sensory acceptability, and color of the bamboo shoots were significantly preserved and were 25.39 mg CO2 kg−1 h−1, 7.55, and 77.65, respectively. Moreover, the polyphenol oxidase (PPO) and peroxidase (POD) activity of the treated bamboo shoots were inhibited effectively. In addition, the samples that were treated at 400 MPa for 15 min displayed the lowest firmness and microbiological content which at 51.15 N and 84.6 CFU g−1, respectively, while the samples treated at 300 MPa for 10 min showed slightly higher values. In conclusion, these results demonstrate that HHP treatment can be considered efficient in preserving the quality of bamboo shoots during storage at room temperature.
The Study on the Interaction between Ethyl Xanthate and Pyrrhotite in Electrochemical Flotation by FTIR Spectroscopy

The flotation behavior of pyrrhotite was investigated by using ethyl xanthate as a collector. The results showed that pyrrhotite had good floatability when pH=1～11, and poor floatability when pH12. The electrical potential of pulp was adjusted by using ammonium persulfate [(NH 4) 2S 2O 8] and sodium thiosulfate (Na 2S 2O 4). The relationship between floatability and electrical potential pulp for pyrrhotite in different pH value has been investigated, obtaining potential-pH range for floatable pyrrhotite. The mechanism of action for ethyl xanthate and production on the surface of pyrrhotite has been investigated by FTIR spectroscopy, and it is found when pyrrhotite acting with ethyl xanthate in the different pH value and at the different electric potential, the infrared absorption and recovery of pyrrhotite has a corresponding relationship. The main adsorption product on pyrrhotite is dixanthogen.
Autocrine and paracrine stimulation of dopamine secretion by human neural stem cells: Role BDNF and GDNF

Background: Neural stem cells are multipotent cells which are capable of self-replication and differentiation into neurons, astrocytes or oligodendrocytes in the central nervous system. Therefore, one can expect that NSC transplantation can ultimately provide a better therapeutic approach in the treatment of neurodegeneration, like Parkinson’s Disease (PD). Aim: In order to use the therapeutic potential of neural stem cells, it is essential to fully understand the cellular and molecular mechanisms involved in the function of Dopamine secretion by the cells. Methods: We assayed the growth potential and DOPAmine production of hNSCs in presence of neurotropic factors. Release of neurotropic factors by hNSCs also determined by ELISA. Results: We found that hNSCs can secrete DOPAmine as well as some neurotropic factors, like Brain-Derived Neurotropic Factor (BDNF) and Glial cell-Derived Neurotropic Factors (GDNF). These factors can further supports the proliferation of hNSCS and DOPAmine production ability of the neural cells. Conclusion: That way, an Autocrine-Paracrine regulatory system have been established in the neural cells. *Correspondence to: Ashok Chakraborty, Chief Scientist, Allexcel, Inc., 123 Wood Street, West Haven, CT 06484, USA, E-mail: ashok.chakraborty@allexcel.com
