Abstract

Bacterial Mn(II) oxidation is believed to play a dominant role in accelerating the rate of Mn biomineralization in nature. Commonly, bacteria adopt two ways concerning Mn(II) oxidases and reactive oxygen species to oxidize Mn(II). In this study, a new strategy for bacterial Mn(II) oxidation involving the pyocyanin, a greenish blue phenazine pigment from Pseudomonas aeruginosa, was discovered. To begin with, a bacterial strain L3 was isolate from soils and identified as Pseudomonas aeruginosa, which exhibited the ability of Mn(II) oxidation. Next, the pyocyanin was purified from strain L3 cultures and proven to be involved in Mn(II) oxidation. Particularly, the oxidation of Mn(II) by pyocyanin was dependent on its ambient pH. In comparison with pH of 5 and 7, pyocyanin (the initial value of OD387 was 0.56 at pH 2) showed a stronger capability of oxidizing Mn(II) at pH of 9, reaching 144.03 µg L− 1 of Mn oxides after 108 h of Mn(II) oxidation, while pyocyanin ultimately produced 43.81 µg L− 1 at pH of 7 and 3.32 µg L− 1 at pH of 5, respectively. Further, strain L3 cultures were fractionated into three parts, i.e., the cell culture solution, fermentation supernatant, and cell suspension, and the Mn(II)-oxidizing activity was found to be distributed in the cell culture solution and fermentation supernatant, as evidenced by the formation of blackish glossy Mn oxides. Specifically, in the first half, the rate of Mn(II) oxidation by the fermentation supernatant was higher than that by the cell culture solution, whereas in the second half, the cell culture solution showed the much higher Mn(II)-oxidizing activity than did the fermentation supernatant. Last but not least, the collective results from mineral characterization demonstrated that, the Mn oxides produced by P. aeruginosa strain L3, either by the cell culture solution or by the fermentation supernatant, were bixbyite-type Mn2O3 with poor crystallinity.
Informality and energy efficiency in Africa: Evidence from symmetric and asymmetric (nonlinear) panel ARDL cointegration approaches

Published: March 2024

Abstract

Energy efficiency is a key component of sustainable and inclusive growth for African countries. However, the informal economy which is prevalent in Africa, affects the continent’s energy efficiency performance. This study therefore investigates the asymmetry in the nexus between the informal economy and energy efficiency. The study employs data on 46 African countries spanning 1990-2017. To measure energy efficiency, the study estimates an energy distance function using Stochastic Frontier Analysis instead of the commonly used energy intensity measure in previous studies. The symmetric and asymmetric panel auto-regressive distributed lag (PARDL) models and the Panel Quantile Regression methods are used to examine the nexus with emphasis given to the asymmetric effects. First, we find considerable variability in energy efficiency performance in African countries. We also find a declining trend in efficiency scores. The results point to a large scope for energy efficiency improvements, showing that the elimination of all types of energy inefficiencies could realise energy savings of up to 58%. Second, the asymmetric PARDL regressions show a decline in energy efficiency performance in response to a positive shock that increases the size of the informal economy and an increase in performance in response to a negative shock that shrinks the size of the sector. Third, we find a positive association between technical innovation and an effect of foreign direct investment on energy efficiency that varies with the method of estimation. Among other things, the study recommends a policy focus aimed at incentivising businesses to formalize operations. JEL classification: Q43, Q48, O17, O13

Abstract

As the world's population grows, so does human activity and industry, and Africa's principal source of energy is fossil fuel. These energy sources are toxic and polluting to our environment (Climate Change, food scarcity, and poverty), as well as to animals and plant life. There was widespread concern about the energy sector's economic, environmental, and social alternatives for mitigating these consequences on a worldwide scale. As a result, the world faces a huge challenge in overcoming them by progressively shifting away from fossil fuels and toward a cleaner, healthier source of energy known as Renewable Energy Sources (RES). Africa is rich in natural and mineral resources, and it is one of the world's greatest producers of primary energy. We used Scopus databases to conduct a thorough examination of numerous earlier studies of GIS-based spatial modelling on renewable energy around the world to understand how GIS-based spatial modelling can help. The findings found that there are greater gaps in the field; there are 28 documents worldwide, with Germany having the most publications, while African countries have none. Although only 3.3 percent of the extracted documents are from the field of mathematics and 3.3 percent from Computer Science, many of the models originated from Mathematical Sciences, such as Computer Science, statistics, or mathematics, this is a multidisciplinary area where research from various fields contributed to the development of this field. We Proposed GIS-based Clustering Methodology for African Countries Renewable Energy Consumptions and Production that can give more insight on African energy situations. Recommendations for exaltation were offered in especially for Africa as well as researchers in the field of mathematical sciences, environmental sciences and technology and other related areas.

Abstract
Background
The COVID-19 pandemic has caused an unprecedented health, social and economic crisis worldwide, as the SARS-CoV-2 virus has managed to cause a major threat with significant morbidity and mortality in certain population groups. The risk of the virus is exacerbated by its easy transmission and continued spread, despite multilevel interventions, extensive containment measures and vaccination. Vaccine hesitancy refers to a person’s reluctance, delay in accepting or even refusing to be vaccinated despite available vaccination services.
Objective
To investigate the factors that influence health professionals and students of health sciences to accept, or not, a booster dose of a COVID-19 vaccine. Sub-objectives were to assess vaccine hesitancy, and specifically those of booster doses, and the presentation of views and attitudes in the above population groups.
Methods
The relevant bibliography was searched electronically in scientific databases such as PubMed, Embase, Cochrane Library and Scopus until August 2023. The main selection criteria were mainly descriptive studies, published in English and Greek. The subjects were human over 18 years old. The time frame of this search was the last four years.
Results
From the results of the systematic review, it was shown that many different factors influence the intention of both healthcare workers and students, as well as those in the general population, to accept a COVID-19 booster dose vaccine. At the same time, the health professionals and students of different countries and continents -that were studied- present diverse socio-demographic characteristics that influence their willingness, or not, to be vaccinated.
Conclusions
COVID-19 booster doses offer further immunity and reduce severe impacts of the disease, such as hospitalization and death. Since health professionals play a critical role in shaping local communities’ attitudes towards vaccines, their beliefs and attitudes play a crucial role. For this reason, it is recommended both training students and healthcare workers via competent institutions, as well as to mobilize and sensitize them, in order to base their attitudes on evidence-based practice. As new technologies and policies are built around COVID-19 vaccines, ongoing testing of their effectiveness, and updated guidelines according to the population group are proven vital to the impact of the disease. Further future studies are necessary.

Abstract
In this paper discusses the thought of philosophy in seeking the existence of God. So God in human view is very interesting in terms of existence and existence, the reason of man is not able to find and show the presence of human rationally. So that the notoriousness of God from the realm of rational and sought after the existence of it, he bore many major religions in the world, all religions believe that one God is strongest. Then the pilots arose, and the existence of the Lord, that was: 1. Saint Augustine who believed that God was by looking at the history of the drama of Creation, 2. Thomas Aquinas, He combined the thought of Aristotle with Christian Revelation. The truth of faith and the perceived religious experience are able to understand God, 3. Descartes He thought of the Lord commencing from his main principle which is “a combination of Catholic and scientific Pietism”, 4. Immanuel Kant with his methods in seeking the existence of God with his moral law, 5. Alfred North Whitehead He used religious dogma adopted by humans and then sought the truth of the religion from whom.
Keywords: Philosophy of Deity, human reason for God, theism as the concept of deity.

Abstract
This article examines the science of laduni and how to acquire it. Laduni science is generally perceived as a supernatural science that cannot be obtained aside from by few individuals. This knowledge is often associated with things that happen abruptly without any preceding process. Muhammad Lutfi Ghozali disproved this assumption by proposing logical, rational arguments and sticking to the naṣ of the Qur'an and Hadith. Muhammad Luthfi Ghozali explained that laduni science has an analytical mechanism. Those who understand the substance of laduni science and construct causal mechanisms will be achievable to acquire this knowledge. The thought of Muhammad Lutfi Ghozali places a comprehension of laduni science that seems mystical and irrational.

Particle separator with vortex claw: an efficient and new technology
Authors: He Cheng , Chittibabu Padala , Nguyen David , Rochfort Quintin 
Published: March 2024

Abstract

Despite facing many challenges, the exploration of using natural forces and mechanisms besides gravity to enhance particle settling has never ceased. A novel particle separator design, which utilizes multiple vortexes to enhance particle settling, was proposed in this study. The basic principle is using the fluid's energy to generate small swirling currents in a specially designed vortex claw generator. These currents bring suspended particles from the rapid and turbulent inflow to relatively quiet water regions, separating them from the main flows and reducing their travel distance to the wall. To verify the new separator design's performance, comparison studies were carried out in the laboratory using physical models. The results showed that the new design had much higher particle capture rates for the same inflow rates and tested particle sizes. Most importantly, it was able to effectively remove small particles, and particle capture rates were much less affected by fluctuations in inflow rates. Since most existing particle separators failed to perform well under large inflow rates, these characteristics make the new design stand out from other separators. Due to its special structure, its treatment capacity can also be easily increased without changing its horizontal separator size.

Abstract

Water scarcity is a major global challenge that affects both developed and developing countries, with Indonesia serving as a prime example. Indonesia's archipelagic nature, combined with its dense population, exacerbates the severity of water scarcity. The increased population density in these areas raises the demand for water resources, putting a strain on the available supply. The purpose of this research was to create porous mortar filters (PMFs) with different ratios (1:4, 1:5, and 1:6) by incorporating 10, 15, and 20% adsorbent material by weight of fine aggregate. The research was carried out in three stages: determining PMF properties, preparing synthetic wastewater, and assessing treatment effectiveness. Various PMF compositions consistently achieved notable success, with reductions in total dissolved solids and turbidity exceeding 25 and 75%, respectively. The PMF performed admirably in eliminating bacterial concentrations, achieving a 100% removal rate, and was critical in efficiently reducing metals, with compositions achieving over 80% reduction for manganese (Mn) and 38% reduction for iron (Fe). PMF emerges as a practical solution as a cost-effective and simple water treatment technology, particularly suitable for areas with limited technological infrastructure and resources, providing accessible water treatment for communities facing challenges in this regard.

Published: March 2024

Introduction:
Using sports supplements is a common strategy for improving athletic
performance. The prevalence of using sports supplements among adolescent and young athletes
has been increasing in recent years.

Methods:
This descriptive-analytical study was performed on 200 bodybuilding athletes. The data
collection tool was a pre-made questionnaire. The questionnaire was distributed among the athletes
by available methods and collected after filling out. The chi-square test, Fisher's exact test,
and logistic regression model were used to analyze the data.

Results:
The prevalence of using sports supplements was 62.5% (n=125), with males accounting
for 67.5% (n=135) of the consumers. Various forms of proteins (43.5%, n=87), vitamins (40.5%,
n=81), and hormones (38.5%, n=77) were the most commonly recommended supplements by the
coaches (58.4%, n=73) and other athletes (31.2%, n=9). The sports supplements have been considered
to have no side effects by 16.8% (n=21) of the athletes; however, 19.2% (n=24) mentioned
cardiac adverse events, and 13.6% (n=17) pointed to renal complications as potential consequences
of supplement use. The results of statistical tests and a logistic regression model showed
a statistically significant relationship between sex, age, education and income, and sports supplement
use (p=0.001).

Conclusion:
According to the results of this current study, a significant proportion of bodybuilding
athletes take sports supplements without being aware of the side effects. Therefore, it is necessary
to develop an educational program to inform the population about the mechanism of action of
supplements in the body and also educate athletes and coaches about the correct use, side effects,
and irreversible consequences of improper supplements use.

Introduction:
Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) caused the outbreak of coronavirus disease 2019 (COVID-19) in late 2019 in Wuhan, China. In early 2020, the disease spread rapidly around the world. Since the pandemic, SARS-CoV-2 has evolved dramatically into a wide variety of variants endowed with devastating properties. As of March 6, 2022, five SARS-CoV-2 variants of concern, including Alpha, Beta, Gamma, Delta, and Omicron strains have been identified. Due to the crucial importance of understanding the differences between the Omicron and Delta variants, this systematic review was conducted.

Methods:
This systematic review investigated new variants of Omicron SARS-CoV-2 based on cur-rent studies. Online databases were searched for English articles as of January 03, 2023. Selection of publications was a two-step process of title/abstract and full-text assessment against eligibility crite-ria. The relevant data from the included articles were systematically collected and organized in a designed table for analysis. To ensure the quality of the review, the PRISMA checklist and Newcas-tle-Ottawa Scale (NOS) of quality assessment were utilized.

Results:
The data extracted from 58 articles were analyzed, including 10003 pieces of evidence. Lower risk of hospitalization, ICU admission, and mortality after vaccination were reported in the Omicron variant compared to the Delta variant. Additionally, the Delta variant led to more severe clinical symptoms in comparison to the Omicron variant.

Conclusion:
The Omicron variant of SARS-CoV-2 results in less severe disease outcomes as com-pared to Delta. Nevertheless, it remains crucial to maintain ongoing monitoring, implement contain-ment measures, and adapt vaccination protocols to effectively address the evolving variants.
