The role of vitamin D against COVID-19 infection, progression and severity
...Show More Authors

BACKGROUND: The number of coronavirus disease-19 (COVID-19) positive patients and fatalities keeps rising. It is important to recognize risk factors for severe outcomes. Evidence linking vitamin D deficiency and the severity of COVID-19 is tangential but substantial – relating to race, obesity, and institutionalization. OBJECTIVE: This study aims to examine the function of vitamin D and nutritional defense against infections such as COVID-19, which is the goal of this research. METHODS: This study includes observational cohort, cross-sectional, and case-control studies that estimated variances in serum levels of vitamin D among patients with mild or severe forms of COVID-19, and in patients who died or were discharged from hospitals. Studies that assessed the risk of developing severe disorder or death in patients with vitamin D deficiency, defined as levels of vitamin D< 20 ng/mL, were also encompassed. RESULTS: In a retrospective study on 464,383 individuals, results showed that individuals who had the highest risks for severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection, and for COVID-19 severity when infected, had vitamin D levels < 30 nmol/L; Odds Ratio (OR) were 1.246 [95% Confidence Interval (CI): 1.210–1.304] and 1.513 [95%CI: 1.230–1.861], respectively. Additionally, in a retrospective observational study of 191,779 individuals in the USA. The SARS-CoV-2 positivity rate was greater in the 39,190 subjects with vitamin D < 20 ng/mL [12.5%, 95% C.I. 12.2–12.8%] than in the 27,870 subjects with sufficient serum vitamin D levels [8.1%, 95% C.I. 7.8–8.4%] and in the 12,321 subjects with serum vitamin D ⩾ 55 ng/mL [5.9%, 95% C.I. 5.5–6.4%]. CONCLUSION: People hospitalized for COVID-19 should be checked for vitamin D status and supplemented, and high-dose-in testing should be considered in the recovery trial. More importantly, screening for malnutrition and the administration of the best nutritional supplements are essential for the immune system of the human body to function as it should be. Thus, nutritional supplementation is crucial for people with risk factors as well as older adults with compromised immune systems.

THE ROLE OF DYNAMIC PROGRAMMING IN THE DISTRIBUTION OF INVESTMENT ALLOCATIONS BETWEEN PRODUCTION LINES WITH AN APPLICATION
...Show More Authors

At present, the ability to promote national economy by adjusting to political, economic, and technological variables is one of the largest challenges faced by organization productivity. This challenge prompts changes in structure and line productivity, given that cash has not been invested. Thus, the management searches for investment opportunities that have achieved the optimum value of the annual increases in total output value of the production line workers in the laboratory. Therefore, the application of dynamic programming model is adopted in this study by addressing the division of investment expenditures to cope with market-dumping policy and to strive non-stop production at work.

ACTINOMYCETES GENERAL CHARACTERISTICS AND THEIR ROLE IN SOIL, PLANT, AND HUMAN *HEALTH
...Show More Authors

Actinomycetes are free, spore-forming, high (G+C) ratio (>55%) saprophytic microorganisms that are widely distributed in most soils, colonize plants, and are prevalent in water. This is frequently accompanied by the production of filament airborne mycelium. Actinomycetes are well-known microcolonies for creating antibiotics and other critical bioactive components that are beneficial to humans. Approximately 70% to 80% of commercially available medications and antiviral active compounds have been synthesized so far. Secondary metabolites produced by microbes have the potential to be used in a variety of sectors, including antimicrobial agents, enzyme technology, pigment manufacture, antitumor agents against cancer cells, and toxin pr

Novel derivatives of 1-(´1, ´3, ´4, ´6-tetra benzoyl-β-D-fructofuranosyl)-1H- benzotriazole and 1-(´1, ´3, ´4, ´6-tetra benzoyl-β-D-fructofuranosyl)-1H- benzotriazole carrying Schiff bases moiety were synthesised and fully characterised. The protection of D- fructose using benzoyl chloride was synthesized, followed by nucleophilic addition/elimination between benzotria- zole and chloroacetyl chloride to give 1-(1- chloroacetyl)- 1H-benzotriazole. The next step was condensation reaction of protected fructose and 1-(1-chloroacetyl)-1H- benzotriazole producing a new nucleoside analogue. The novel nucleoside analogues underwent a second conden- sation reaction with different aromatic and aliphatic amines to provide new Schiff b

Impact of Different H/D Ratio on Axial Gas Holdup Measured by Four-Tips Optical Fiber Probe in Slurry Bubble Column
...Show More Authors

In wide range of chemical, petrochemical and energy processes, it is not possible to manage without slurry bubble column reactors. In this investigation, time average local gas holdup was recorded for three different height to diameter (H/D) ratios 3, 4 and 5 in 18" diameter slurry bubble column. Air-water-glass beads system was used with superficial velocity up to 0.24 m/s. the gas holdup was measured using 4-tips optical fiber probe technique. The results show that the axial gas holdup increases almost linearly with the superficial gas velocity in 0.08 m/s and levels off with a further increase of velocity. A comparison of the present data with those reported for other slurry bubble column having diameters larger than

The role of artistic elements in revealing psychological emotions in the play (Gan Riki) (Analytical review)
...Show More Authors

Our research sheds light on one of the most important aspects of David Grossman's play, "Ricky's Garden, גן ריקי " which is characterized by its realistic portrayal of characters. Grossman gradually moves towards the inner awareness of his characters, expressing their emotions and thoughts through conversations and emotional conflicts, referring to their past and rooted background. Grossman transformed the main subject of his play (psychological depth) into a presentation and arrangement of all the elements of the play in a way that expresses emotional nature more powerfully by each child in the garden. This is reflected in their actions and words, making Grossman's works suitable for study and always of interest to specialized resear
