Sensitivity of numerical parameters on DEM predictions of sediment transport

ABSTRACT The current work presents a sensitivity study of selected numerical parameters on the large-eddy simulation–discrete element method predictions of sediment transport in a unidirectional open turbulent channel. The sensitivity of the particle friction factor, restitution coefficient, and spring stiffness used in the soft sphere collision model is tested in the three regimes of sediment transport comprising of essentially no motion, bed load, and suspended load flow regimes. The simulations are run for 10 s using base values of the parameters of interest (reference calculation), then one parameter is changed at a time and the corresponding change in quantitative result is observed for the following 15 s where averaged results in the last 10 s are compared to the reference calculation. The sensitivity analysis shows that the underpredicted sediment transport in the suspended load regime can be bridged by moderately decreasing the friction factor of the particles from 0.6 to 0.25. The impact of the same change in bed load regime is not as significant. Both the coefficient of restitution and the particle stiffness show less significant to negligible impact as compared to the friction factor.
Metal ion chelation and anti-glycation properties of polysaccharides of Phyllanthus amarus plant

The study was conducted to investigate the in vitro anti-glycation activity of Phyllanthus amarus plant extract. The above plant has been used for centuries for its useful health benefits in variety of inflammatory diseases. In current study, antioxidant, metal chelating and ferric ion reducing and antiglycation property was studied for the polysaccharides isolated from Phyllanthus amarus plant extract. At 25 μg/mL sugar concentration and Vitamin C, gave 57 % and 65 % inhibition in hydroxyl radical scavenging assay and in Antiglycation assay the extract and vitamin C showed 65% and 87% respectively. It also had metal ion chelating (PAPE 74%, Ascorbic acid 88%) and ferric ion reducing activity showed by PAPE IS about 68% when compared to standard metal ion chelator EDTA 90%. It inhibited fructosamine formation by 52% after 3 days of incubation. The above studies gave an opinion that the inhibition of glycation exhibited by extract was due to its free radical scavenging property but also due to the modification in the amino or carbonyl groups resulted in the inhibition of fructosamine formation. The polysaccharides of the extract may be donating the hydrogen atom to the free radical, and exhibiting the antioxidant activity. So polysaccharide isolated from Phyllanthus amarus plant may use in preventing many free radicals induced diseases and also in delaying or preventing complications of diabetes.
Knowledge Hiding as an Unprecedented Auxiliary in the Knowledge Management Process for Protection and to Achieve Innovation: The Case of a Pharmaceutical MNE Operating in Egypt

This paper investigates the process and strategies used by a pharmaceutical MNE in Egypt to acquire, assimilate, transform, apply and protect its knowledge for the purpose of achieving innovation. The analysis is conducted through the lens of absorptive capacity theory and based on seven interviews with key stakeholders to explore how knowledge protection practices and supporting mechanisms were applied to achieve innovation and organizational effectiveness. , Thematic analysis reveals that Knowledge infrastructure capabilities constitute the backbone of knowledge processing capabilities, supported by other constituents such as appropriability regime mechanisms, the role of management (HRM), knowledge management approach, knowledge hiding, and the absorptive capacity. The study concludes that successful knowledge management is a byproduct of integrating knowledge infrastructure capability with processing capabilities, and mediated by knowledge hiding mechanisms and strategies. The findings offer a valuable empirical perspective from a pharmaceutical MNE operating in Egypt and provide new insights into the nature of the intermediating influences of knowledge management processes that lead to innovation and superior organizational performance.
MACROELEMENTS CONCENTRATION IN PLUM TREE LEAVES AND SOIL IN RESPONSE TO ORCHARD FLOOR MANAGEMENT

The aim of the study was to determine the influence of various methods of orchard floor management on extractable mactronutrients concentration in plum leaves and orchard soil. Study carried out between 2013 and 2015. Standard mineral fertilization on experimental plots was applied. Trees of ‘Valjevka’ plum (Prunus domestica L.), grafted onto Myrobalan seedlings (Prunus cerasifera Ehrh. var. divaricata Ledeb.), were planted in the spring of 2008. From 2009 to 2015, the following methods of soil cultivation under tree canopies were introduced: control with limited weeding around tree trunks; spraying with foliar herbicides; mulching with organic waste, i.e. straw with compost; mechanical soil cultivation with the use of rotary cultivators and hoe; weed mowing. The method of soil cultivation had influence on leaf concentration of phosphorus, potassium, magnesium and calcium, as well as soil concentration content of phosphorus, potassium, and magnesium in particular years of the study or as three-year mean. Orchard floor management did not affect leaf nitrogen concentration in any way. The results showed that regular weed control in the evaluated type of orchard is not necessary for properly supplying plum trees with macronutrients.
Factors influencing place of delivery among women residing in Ifakara Town Council, Kilombero District, Tanzania

Background: This study was done to assess factors influencing place of delivery among women residing in Ifakara Town Council, Kilombero district, Tanzania. Method: A community based descriptive cross-sectional study was conducted in February 2021. A total of 135 child bearing women from 3 randomly selected wards of Ifakara Town Council were involved in the study. Structured pre-tested questionnaire with key information was used to collect desired data. Results: More than half 55.6% of the women had health facility delivery and 44.4% of them had home delivery. The most common reason for home delivery was sudden onset of labor 50.4%. Other reasons for home delivery were age of 26 and above, parity of four, and education of mother. Conclusion: Maternal health services, such as antenatal care, skilled assistance during delivery and post-natal care, adequate equipment in health facilities, play a major role of in the reduction of maternal morbidity and mortality. Therefore, efforts should be made both at community and government levels to increase health facility delivery.
COMPARISON ON VEGETATION COMPOSITION AND STRUCTURE OF EXCLOSURES VS. OPEN GRAZING LANDS IN NORTHERN ETHIOPIA

This study was conducted with the objectives of study investigates, compare, and try to describe the floristic composition and structure of the vegetation of exclosures and open grazing lands. A stratified preferential sampling design technique with flexible systematic model was used for data collection. Data on vegetation and environmental parameters were gathered from 120 quadrants (90 from restorations or exclosures of different ages and 30 from adjacent open grazing lands), of 20 m x 20 m (400 m2) size. Species richness and the presence or absence of herbaceous plants were recorded like soil samples in a 2 m x 2 m (4 m2) subplot inside each main quadrant from five points, one at each corner and one at the center. A total of 142 plant species belonging to 118 genera and 52 families were identified. All exclosures displayed higher plant species richness, diversity, and aboveground standing biomass compared to the adjacent open grazing lands. Consideration of edaphic (e.g. soil total nitrogen, available phosphorus, CEC, exchangeable bases, soil pH and soil texture) and site (e.g. Stoniness, Grazing) variables will help to optimize the selection of areas for the establishment of future exclosures. Moreover, our study suggests that with time exclosures may increasingly obtain an important role as refugees and species pool similar to church forests and should be protected and managed in a sustainable manner. However, economic and social impacts of exclosures should be included in feasibility studies before establishing exclosures in the future. Altitude, Grazing and some soil parameters like Mg were the major environmental factors in the division of the vegetation into plant community types. The result of the frequency distribution of woody species showed a high proportion of small-sized individuals in the lower diameter classes indicating good recruitment potential of the forest patches and the rare occurrence of large individuals. Such trend was probably caused by past disturbance of the original vegetation resulting in a succession of secondary vegetation. In addition, the analysis of species population structure indicated that some tree species had abnormal population structure with no or few individuals at lower size classes. Moreover, assessment of regeneration status on the basis of age classes indicated that significant proportion of woody species were represented by few or no seedlings, entailing that they were under threat. Substantial numbers of forest species were found to have irregular population structure and are in reduced regeneration status. To prevent local extinction of these species, present efforts of nursery establishment and plantation of indigenous species in the exclosures should be strengthened and extended.

Revision 2 ( FGE . 77 Rev 2 ) : Consideration of Pyridine , Pyrrole and Quinoline Derivatives

The Panel on Food Contact Materials, Enzymes, Flavo urings and Processing Aids of the European Food Saf ety Authority was requested to consider evaluations of flavouring substances assessed since 2000 by the Jo int FAO/WHO Expert Committee on Food Additives (JECFA), and to decide whether further evaluation is necessary, as laid down in Commission Regulation (E C) No 1565/2000. The present consideration concerns a group of 22 pyridine, pyrrole and quinoline derivat es evaluated by JECFA (63 rd meeting). The revision of this consideration is made since additional toxicity dat a have become available for 1-furfurylpyrrole [FL-n o: 13.134]. The data are intended to cover the re-evaluation of this substance and 2-acetyl-1-ethylpyrrole [FL-no: 14.045] and 2-acetyl-1-methylpyrrole [FL-no: 14.046]. The P anel concluded that for 6-methylquinoline [FL-no: 1 4.042], the genotoxicity data available do not clear the co ncern with respect to genotoxicity in vitro and accordingly the substance is not evaluated through the Procedure. F or 21 substances [FL-no: 13.134, 14.001, 14.004, 14 . 007, 14.030, 14.038, 14.039, 14.041, 14.045, 14.046, 14. 047, 14.058, 14.059, 14.060, 14.061, 14.065, 14.066 , 14.068, 14.071, 14.072 and 14.164] considered in this FGE, the Panel agrees with the JECFA conclusion, “No saf ety concern at estimated levels of intake as flavouring substances” based on the MSDI approach. Besides th e afety assessment of these flavouring substances, the spec ifications for the materials of commerce have also been evaluated, and the information is considered adequa t for all the substances. © European Food Safety Authority, 2015
Modelling Chablis vintage quality in response to inter-annual variation in weather

The weather during grape production affects wine quality. Changes in the weather in the Chablis region of France and in the quality of Chablis wines (vintage scores) from 1963 to 2018 were analysed. Chablis wine quality improved over this period, with no Poor vintages after 1991. Summer temperature and sunshine duration both increased progressively between 1963 to 2018 with fewer frost days but no linear change detected in precipitation. Chablis vintage score was modelled as a function of mean temperature from April to September (curvilinear relation, maximum score at 16–17 °C), mean minimum temperature in September (an index of cool nights; negative relation), and total rainfall from June to September (negative relation). This simple three-factor model distinguished between Poor and higher-quality Chablis vintages well, but less so between Good and Excellent vintages. Application of the model to different climate change scenarios (assuming current viticultural and oenological practices) suggests that vintage scores will decline (slightly to substantially, dependent upon emissions scenario) by the 2041 to 2070 period. This reduction in quality would, however, be minimised if the warming of cool nights is less than currently forecast. The Chablis vintage score model may help identify sites with suitable climates for premium white wine from Chardonnay grapevines in emerging cool climate viticulture regions as well as aiding Chablis producers mitigate the effects of climate change.

Department of Urology, Beijing Jishuitan Hospital, Beijing 100035, People’s Republic of China Purpose: Long non-coding RNAs have been found to be involved in bladder cancer development. This article studied LINC00963 effects on bladder cancer progression to provide a novel treatment target. Patients and Methods: Totally 56 bladder cancer patients participated in this research. Bladder cancer cells were transfected. Cell counting kit 8 assay and clone formation experiment were used for cell viability and colony formation detection. Cell migration and invasion were determined by Transwell experiment. LINC00963 distribution was explored by cytoplasmic and nuclear extract isolation and quantitative real-time polymerase chain reaction. Luciferase reporter experiment and RNA pulldown experiment were performed to detect the relationship between these two genes. The cancer genome atlas analysis was used for the detection of metastasis-associated protein 1 (MTA1) expression in bladder cancer. Results: LINC00963 was seriously up-regulated in bladder cancer patients. High LINC00963 expression indicated high histological grade and low survival. LINC00963 was obviously up-regulated in bladder cancer cells. Knockdown of LINC00963 significantly reduced bladder cancer cells viability, colony formation, migration and invasion. Luciferase reporter experiment and RNA pulldown experiment revealed that LINC00963 promoted MTA1 expression via directly inhibiting miR-766-3p. MTA1 was up-regulated in bladder cancer patients. MTA1 up-regulation reversed the inhibitory effect of LINC00963 knockdown on bladder cancer cell viability, migration and invasion. Conclusion: LINC00963 functions as an oncogene in bladder cancer by regulating the miR766-3p/MTA1 axis.
Comparative analysis of the physicochemical composition of pea cultivars

Peas are an inexpensive nutrient source. Basic information about variation in physicochemical composition is required to manage breeding programs and postharvest operations effectively. Different properties were measured in seeds from 16 promising pea genotypes to study variability between lines, degree of genetic parameters, and associations among different traits. Seed weight and diameter, pH, and titratable acidity showed the highest values for broad-sense heritability and the most negligible differences between the phenotypic and genetic coefficient of variation, indicating that these traits’ variability was predominately due to genotypic differences. Genotypes had a wide-range profile that could be related to morphological and physiological properties. Yellow varieties showed superior values for weight and sizes (27.84 g; 0.57 cm) and small changes in diameter after hydration (48.35 %), while wrinkled varieties showed inferior moisture content (9.54 %), higher hydration capacity (1,314.66 g H2O/kg seeds), and protein content (28.88 %). Cuarentina and B315 were the more resistant and firmer materials; B315 also had the highest water hydration capacity, which would be appropriate for canning. Polyacrylamide gels demonstrated differences in protein composition; Gypsi contained more legumin (47.27 %) than the other genotypes, which is more beneficial nutritionally, and contained less convicilin (7.06 %), making it suitable for the food industry. Using accelerated aging, we studied color changes due to storage and established that the Viper line was highly tolerant to it. We could identify lines that may be exploited by industry or quality breeding programs.
Functional skills for learners with special educational needs amidst the COVID-19 pandemic

The key purpose of this study is to determine the functional skills of learners with special educational needs (LSENs) in terms of life skills, social skills and community-based learning skills in the identified schools in Toledo City Division. It employed both quantitative and qualitative research methods to assess the functional skills of LSENs amidst the pandemic as rated by the parents. The respondents were selected through purposive sampling technique. The study utilised an adapted the research tool. The findings show that most of the learners were aged 10 years old or older, male, non-graded and with intellectual disabilities, while most of the parents were poor, housewives and had a high school level. The result also revealed that parents rated LSENs with moderate functional skills. The challenges encountered by parents include lack of relevant training, lack of knowledge about child care and lacks of time. With this, the school administrators should design responses with specific contexts and consider implementation of the functional skills of learners. Hence, the adoption of the parental intervention plan for LSENs is recommended. Keywords: Functional skills, special educational needs, life skills, social skills, community-based learning skills.
OPERATING CAPACITY OF ANTI-OXIDIZING COATING IN HYPERSONIC FLOWS OF AIR PLASMA

In this paper, we present the results of investigations of degradation processes that occur in the structure promising high-temperature anti-oxidizing of heat-resistant coating of the Si–TiSi2–MoSi2–B–Y system in hypersonic flows of air plasma. The coating is designed to protect a wide range of heat-resistant materials (carbon–carbon and carbon–ceramic composites, coal–graphite materials, alloys based on Nb, Mo, W, etc.). It is found that the coating operating capacity at surface temperatures [Formula: see text] 1820–1830∘C is provided by the structural-phase state of its microcomposite main layer and formation on the coating surface of a heterogeneous passivating protective film. It is based on borosilicate glass reinforced by rutile microneedles. The mechanism of coating destruction at [Formula: see text] 1850–1860∘C is erosion loss of oxide film as well as generation and growth of gas-filled cavities at the “coating main layer–oxide film” interface. As the pressure of saturated vapor of gaseous oxidation products (SiO, CO, MoO3 and B2O3) exceeds that of the ambient, the oxide film integrity is disrupted and oxidation process becomes active. The rates of erosion loss and sublimation grow as operating temperature increases and ambient pressure decreases.
The content of silver, aluminum, and zinc in wild edible mushroom Macrolepiota procera

The content of selected elements (Ag, Al, and Zn) in wild edible Parasol mushroom (Macrolepiota procera Scop. Singer) collected from five sites in Slovakia – Lazy pod Makytou, Lozorno, Nemečky, Tesáre, and Zbyňov was investigated. The element analysis was determined using the ICP-OES method. The average concentrations of Ag, Al, and Zn in M. procera caps ranged as follows: 0.41 – 3.23, 16.6 – 113, and 73.4 – 111 mg kg-1 dry weight, respectively. Also, Spearman’s correlation test was used to determine the correlations between Parasol mushroom caps and stems in the content of Ag, Al, and Zn. Subsequently, the obtained data on the content of the monitored elements in M. procera caps were used for the evaluation of health risks arising from the consumption of M. procera. Although mushrooms are an important part of the diet, they are consumed mainly as a seasonal delicacy therefore, the intake of the monitored elements from the consumption of M. procera may be limited. Regular and long-term consumption of M. procera caps from investigated sites does not pose any health risks to the consumers.
Blue carbon stocks and exchanges along the California coast

Abstract. Salt marshes and seagrass meadows can sequester and store high quantities of organic carbon (OC) in their sediments relative to other marine and terrestrial habitats. Assessing carbon stocks, carbon sources, and the transfer of carbon between habitats within coastal seascapes are each integral in identifying the role of blue carbon habitats in coastal carbon cycling. Here, we quantified carbon stocks, sources, and exchanges in seagrass meadows, salt marshes, and unvegetated sediments in six bays along the California coast. In the top 20 cm of sediment, the salt marshes contained approximately twice as much OC as seagrass meadows did, 4.92 ± 0.36 kg OC m−2 compared to 2.20 ± 0.24 kg OC m−2, respectively. Both salt marsh and seagrass sediment carbon stocks were higher than previous estimates from this region but lower than global and US-wide averages, respectively. Seagrass-derived carbon was deposited annually into adjacent marshes during fall seagrass senescence. However, isotope mixing models estimate that negligible amounts of this seagrass material were ultimately buried in underlying sediment. Rather, the vast majority of OC in sediment across sites was likely derived from planktonic/benthic diatoms and/or C3 salt marsh plants.
The impact of heating, ventilation, and air conditioning design features on the transmission of viruses, including the 2019 novel coronavirus: A systematic review of filtration

Historically, viruses have demonstrated airborne transmission. Emerging evidence suggests the novel coronavirus (SARS-CoV-2) that causes COVID-19 may also spread by airborne transmission. This is more likely in indoor environments, particularly with poor ventilation. In the context of potential airborne transmission, a vital mitigation strategy for the built environment is heating, ventilation, and air conditioning (HVAC) systems. HVAC features could modify virus transmission potential. A systematic review following international standards was conducted to comprehensively identify and synthesize research examining the effectiveness of filters within HVAC systems in reducing virus transmission. Twenty-three relevant studies showed that: filtration was associated with decreased transmission; filters removed viruses from the air; increasing filter efficiency (efficiency of particle removal) was associated with decreased transmission, decreased infection risk, and increased viral filtration efficiency (efficiency of virus removal); increasing filter efficiency above MERV 13 was associated with limited benefit in further reduction of virus concentration and infection risk; and filters with the same efficiency rating from different companies showed variable performance. Increasing filter efficiency may mitigate virus transmission; however, improvement may be limited above MERV 13. Adapting HVAC systems to mitigate virus transmission requires a multi-factorial approach and filtration is one factor offering demonstrated potential for decreased transmission.
