Published: June 2022

Настоящая работа посвящена изучению параметров диффузионного пламени жидкого водорода, возникающего в результате нештатной ситуации с проливом жидкости из технологического оборудования на различные поверхности. Параметры пламени жидкого водорода необходимы для оценки влияния его теплового излучения на окружающие объекты и выбора способа ликвидации последствий аварийной ситуации. Полученные экспериментальные данные по горению жидкого водорода позволили предложить в целях практического применения аналитические зависимости для оценки параметров диффузионного пламени водорода, обычно возникающего после аварийного пролива жидкости на различные поверхности. Эти зависимости удовлетворительно обобщают экспериментальные данные через критерий Фруда и могут иметь практическое применение при решении вопросов по обеспечению пожарной безопасности технологического объекта.
This research work is devoted to the study of the parameters of the diffusion flame of liquid hydrogen which potentially arises as a result of a possible emergency situation with the spillage of liquid from technological equipment. The parameters of the liquid hydrogen flame are necessary to assess the effect of its thermal emission on the surrounding objects and also to choose a way to eliminate the accident and its consequences. The combustion of liquid hydrogen spilled in amount 1-100 liters occurred from various surfaces (metal baking sheets, gravel, water surface, liquid nitrogen surface) and various areas (1-7 m). Special Dewar vessels with volumes from 3 to 120 liters were used for experiments. The amount of spilled hydrogen, the burning time, and the size of the flame were measured during the experiments (based on the results of filming). The ignition of vapors of evaporating hydrogen were performed by an electric spark at a height of 0.5-1.0 m from the surface of the spillage. The obtained experimental results were processed depending on the Froude numbers according to the expression Fr = u / gd, where u - rate of vapor outflow, м · s; u = m/r, m - evaporation rate, kg/(m · s); r - vapor density, kg/m; g - acceleration of gravity, m · s; d - diameter of the “pool” of liquid hydrogen ( evaporation ares), m. The dependence of the dimensionless flame height from the Froude number is obtained in the form L/d = 32(Fr) for Fr = 10 - 10. The dependence of the maximum flame diameter of the number of Fr is obtained in the form D/d = 11(Fr) for Fr = 10 - 10. This paper presents analytical expressions for determining the size of diffusion flames of liquid hydrogen usually occur after an emergency spill. The use of liquid nitrogen in the process of an emergency hydrogen spill can noticeably (by 2 times) reduce the size of hydrogen diffusion flame and reduce the impact of thermal radiation on surrounding objects since the extinguishing of such fires is not regulated by both foreign and domestic regulatory documents.

Published: June 2022

The objective of the study is to investigate the ameliorative potential of date palm tree (Phoenix dactylifera) fruit on cadmium induced kidneydamage in adult Wistar Rat using standard technique. Thirty (30) adult Wistar rats were divided into six groups of five rats per group. Group A (control); Group B (0.1ml/kg body weight of cadmium); Group C (200mg/kg body weight of Phoenix dactylifera); Group D (600mg/kg body weight of Phaoenix dactylifera); Group E (0.1ml/kg body weight of cadmium and 200mg/kg body weight of Phoenix dactylifera); Group F (0.1ml/kg body weight of cadmium and 600mg/kg body weight of Phoenix dactylifera). Treatments were administered once daily for 30 days. After day 30, biochemical and histopathological studies were conducted to appraise oxidative stress and renal toxicity. Serum levels of creatinine, urea, catalase (CAT) and superoxide dismutase (SOD) were quantified. Animals treated alone with cadmium (Group B), showed significant (P < 0.05) increase in serum urea, serum creatinine and CAT, SOD levels statistically. Treatment of rats with Phoenix dactyliferaalongside cadmium (Group E and F) showed significant (P < 0.05) improvement in renal function and restoration of biochemical parameters mentioned earlier. Histopathological findings confirm these conservations. Therefore, the administration of aqueous extract of Phoenix dactylifera has protective effect on cadmium-induced renal toxicity and oxidative stress in wistar rats which can be attributed to Phoenix dactylifera antioxidant activity.

This study assessed toxicity of the crude ethanolic pod extracts of Swartzia madagascariensis Desv in Wistar rats. Forty (40) Wistar rats aged 8–10 weeks were orally administered with crude extracts from pods of S. madagascariensis. Chemical analysis of serum and histopathology of liver and kidney from test animals were performed to determine the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatinine in serum. In addition, serum albumin levels were also determined. The levels of ALT, AST and creatinine were found to be high in groups treated with crude extracts compared to the control group, suggesting some damage in liver cells and kidney of treated groups of Wistar rats. The albumin levels in serum samples of crude extract treated groups were found to be low compared to control group, suggesting some leakage to the urine due to damage in the kidney. Histopathological analyses revealed damages in the liver and kidney treated with 1000 mg/kg of crude ethanolic pod extracts of Swartzia madagascariensis (CEPES) at days 2 and 14, corresponding to what was observed in the biochemical variables. The findings revealed that Swartzia madagascariensis pods are toxic once taken in large quantities (1000 mg/kg).

Exploring Carrier Sense Multiple Access with Collision Avoidance Techniques for Resource Sharing in Broadband Power Line Communications
Authors: Luwemba Godfrey , Kissaka Mussa M. , Mafole Prosper 
Published: June 2022

A resource sharing in power line communications (PLC) for the home network is restricted by the channel assignment techniques which decide who has the right to gain access to send data. The channel assignment techniques include contention-free and contention-based. The former requires high synchronization due to the deterministic round-trip time. Besides, contention-based utilizes CSMA/CA techniques that allow stations in a network to compete for channel access and are suitable for decentralized network topology. However, a trade-off exists between the number of stations required to gain access versus system efficiency. Whilst some research has been carried out on CSMA/CA resource sharing techniques that allow only one user to transmit, there is very little work done on multiuser access to optimize system efficiency and reduce collisions in a network. The purpose of the current study was to review the CSMA/CA techniques for resource sharing to improve system efficiency in power line communications. In carrying out this study, a systematic literature review methodology to evaluate different related works and determine the most suitable approach to allow multiuser channel access was used. The study further demonstrated the impact multichannel access has on system efficiency. In addition, the study provides recommendations for future research.

Authors: Shakib Fardin Al Fahad , Sadat Nazmus , Ahmed Shamim , Nipa Nilufer Yeasmin , Rahman Mashiqur , Uddin Mohammad Borhan 
Published: June 2022

Background: Most medicine users are not aware of the safe disposal of unused or expired medicines. The aim of this study was to know the current knowledge of the disposal practices of unused and expired medicines among the undergraduate pharmacy and other disciplines studying in universities located in different areas of Dhaka city, Bangladesh.
Methods: This was a descriptive, cross-sectional survey, conducted through face-to-face interviews using a structured questionnaire. Returned questionnaires were double-checked for accuracy.
Results: A total of 250 valid questionnaires were returned with a response rate of 100%. Respondents were mainly divided into two categories: pharmacy students (n=150; 60%) and general students (n=100; 40%). Two third of the general students (66%; n=98) and pharmacy students (65.3%; n=66) showed an almost similar response to keeping medicines at home. Overall, the highest common leftover medicines were analgesics (n=181; 27.6%) followed by gastric agents 174 (26.6%). Alarmingly, 85 (34%) respondents usually threw their leftover medicines in the dustbin, however, only very few portions of health science students (8%) have donated their unused medicines to welfare and friends. About 58% of respondents from other disciplines agreed that the necessity of pharmacists counselling people about proper medication disposal is highly required.
Conclusion: Gaps exist in everyday drug disposal practices, therefore cost-effective pharmaceutical waste management programmes supported by government regulatory authorities and media campaigns are needed. Healthcare practitioners and community pharmacists should offer training to educate patients on standard medicine disposal practices. Findings from this study are hoped to assist in creating awareness about appropriate drug disposal practices in households and trigger interest and attention among policymakers about formulating relevant regulations.
How do different communities of pharmacy students in the United Kingdom approach study and personal support?
Authors: Ponikwer Fiona , Dunskute Ugne , Rafique Rumaysa , Patel Bhavik Anil 
Published: June 2022

Objectives: This study aimed to discover how a diverse pharmacy student population in the United Kingdom engages with academic and non-academic support, and what might prevent them from doing so.
Methods: Pharmacy students (in all years of study) completed an online survey seeking information on: demographics; confidence in studying; and where/how students seek academic and personal support. The survey outcomes were statistically analysed to compare differences between Black, Asian and Minority Ethnic (BAME) and white students.
Results: When seeking help from academic staff, 38.8% of BAME students felt they were negatively perceived. All students are significantly more likely to seek help for academic issues than for personal and well-being ones, with most students preferring to ask family and friends rather than university support mechanisms.
Conclusion: The results strongly indicate that support mechanisms present within universities to help students are seldom utilised and may explain the reduced academic performance of both white and BAME students.

Published: June 2022

The Berezin transform $\widetilde{T}$ and the Berezin radius of an operator
$T$ on the reproducing kernel Hilbert space $\mathcal{H}\left( Q\right) $
over some set $Q$ with the reproducing kernel $K_{\eta}$ are defined,
respectively, by
\[
\widetilde{T}(\eta)=\left\langle {T\frac{K_{\eta}}{{\left\Vert K_{\eta
}\right\Vert }},\frac{K_{\eta}}{{\left\Vert K_{\eta}\right\Vert }}%
}\right\rangle ,\ \eta\in Q\text{ and }\mathrm{ber}(T):=\sup_{\eta\in
Q}\left\vert \widetilde{T}{(\eta)}\right\vert .
\]
We study several sharp inequalities by using this bounded function
$\widetilde{T},$ involving powers of the Berezin radius and the Berezin norms
of reproducing kernel Hilbert space operators. We also give some inequalities
regarding the Berezin transforms of sum of two operators.
