Published: June 2024

Engine thermal management systems represent a promising solution to improve the efficiency of current Internal Combustion Engines (ICE) and sustain the transition towards a net zero scenario. The core component of an engine thermal management system is the electric pump, which can adjust the coolant flow rate according to the engine thermal needs. This possibility opens to newer design choices, which can contribute to non-negligible energy savings. In this study, three electric coolant pumps with different maximum efficiencies have been investigated to understand the influence of the design operating conditions on the pump energy absorption. A reference vehicle equipping a 130 HP downsized gasoline engine has been considered. An experimental test bench with a copy of the engine and its cooling circuit has been reproduced, and the electric pumps have been tested at a wide range of rotational speeds and thermostat lifts to obtain their characteristic maps. Once their performances were known, the vehicle was run in three driving cycles consisting of different shares of rural, urban and highway sections, acquiring data from the Electronic Control Unit (ECU). These data have been used to calculate the operating condition and energy absorption of the mechanical pump originally equipped by the vehicle and the electric pumps. The results have been evaluated using a statistical approach, normalizing the instantaneous efficiency by using their maximum efficiency values. The results show that all the electric pumps have lower energy absorption compared to the conventional mechanical actuation, with a reduction of up to 77% of the energy absorption. Considering the vehicle's fuel consumption and the lower heating value of gasoline, the potential reduction of CO2 specific emissions is 1 g/km. The statistical analysis approach showed that the design operating conditions have a higher influence than the maximum pump efficiency. The best performances are achieved through the electric pump with the lowest efficiency, showing a decrease in energy absorption between 10 % and 50% compared to the other electric prototypes, depending on the driving profile.

This study aimed to analyze the correlation between smoking and coronavirus disease 2019 (COVID-19) severity by region and gross domestic product (GDP). The regions were categorized by continent and GDP rankings. Studies conducted between June 3, 2020 and March 27, 2023 were searched to compare the severity of COVID-19 between smokers and non-smokers according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Compared with never-smokers, the smokers’ COVID-19 severity scores were 1.48 (confidence interval [CI]: 1.25–1.75) in Asia, 1.24 (CI: 1.05–1.46) in the Middle East, 1.32 (1.21–1.45) in Europe, 1.39 (1.30–1.49) in North America, 1.69 (1.22–2.34) in South America, and 2.87 (1.82–4.53) in Africa. By GDP, the smokers’ COVID-19 severity scores were higher than those of never-smokers: 1.42 (1.32–1.53) in high-GDP countries, 1.33 (1.25–1.41) in middle-GDP countries (11th–50th), and 1.53 (0.85–2.76) in low-GDP countries. The COVID-19 severity in smokers was significantly higher in low-GDP countries than in high- and middle-income countries. The high COVID-19 death rate among smokers in the African continent and low-GDP countries is thought to stem from the lack of medical management systems compared with other countries. In addition to medical treatment, environmental or socioeconomic factors can increase the severity.
Bathymetric survey and volumetric analysis of Bakolori dam reservoir North West Nigeria
Authors: Shuaibu Ahmad Mahi
Published: June 2024

Many approaches have been devised for measuring water depth in bathymetric surveys, which are used to assess sediment deposited directly in lakes and reservoirs. This technique is mostly used to calculate the reservoir's capacity and the amount of sedimentation that occurs there. The results of the volumetric analysis and bathymetric survey of the Bakolori Dam reservoir, which is situated in Northwestern Nigeria, are presented in this work. During this investigation, the differential Global Positioning System receiver (GPS), automatic level measuring tool, echo-sounder, and engine boat were utilized. ArcGis 10.0 was used to analyze the acquired data. In order to evaluate the reservoir capacity loss during the Bakolori reservoir's operating period as of 1983, the designed computed reservoir capacity was compared with the current bathymetry survey. At a spillway crest elevation of 334 meters above mean sea level (amsl), the reservoir's initial capacity is reported as 430 million cubic meters (MCM). However, the capacity has since been revised to 291 meters at the same level, with a volume change of 139,269,495 m3. As a result, the reservoir's volume changed by approximately 139 MCM during a thirty-five (35) year period of service, representing a loss of storage capacity, while the annual siltation rate was around 3,979,128 m3/a. This indicated that 33% of the reservoir's storage capacity had silted up. This is demonstrated by the aquatic weeds that have grown to a height of 334.21 meters on the lake's surface, rising from the lakebed. Therefore, to prevent total siltation, the dam reservoir needs to be adequately dredged.

Authors: Ergül Zeliha Nur , Karadeniz Rahmi Sinan
Published: June 2024

Objective: To assess the significance of diagnosis, treatment, and management approaches in cases of recurrent ectopic pregnancies.
Material and Method: This study presents the management of a 31-year-old woman with a history of left tubal pregnancy and subsequent left salpingectomy, who presented with a right tubal ectopic pregnancy. Methotrexate (MTX) treatment was initiated due to the absence of contraindications. On the first day of MTX, the patient’s serum βhCG level was 5135.64 U/L, but it continued to rise. Subsequently, the patient received a second dose of MTX. On the fourth day of the second MTX dose, the serum βhCG level was 8333.98 U/L, while on the fifth day of the second MTX dose, the βhCG level dropped dramatically to 6819.35 U/L. Twenty-two days after the second dose of MTX treatment, the serum βhCG level was 848.76 U/L. Transvaginal ultrasound revealed a decrease in the ectopic mass.
Conclusion: Early diagnosis of tubal ectopic pregnancies can be effectively managed through medical intervention, demonstrating a high success rate.

Authors: Kurt Dilara Sarıkaya , Duru Çöteli Ayse Sinem , Kurt Ahmet , Boran Nurettin
Published: June 2024

Aim: The aim of this study was to investigate the results of fertility-preserving and/or radical surgery, the effects of fertility-preserving surgery on fertility and the postoperative recurrence rate in patients with borderline ovarian tumors.
Material and Method: The study included 138 patients who were diagnosed with borderline ovarian tumors in the oncology clinic of a tertiary institution in Ankara. The patients’ data were analyzed retrospectively from the hospital information system. Among 138 patients, age, parity, type of surgery, number of lymph nodes removed, recurrence rates, pregnancy rates after treatment and fertility and recurrence analysis were performed. Recurrence and fertility rates were compared between those who underwent fertility preserving surgery and those who did not.
Results: The distribution of the patıents’ age groups is as follows: 21% of the patients were under the age of 30; 26.1% were between 31-40 years of age, and 21% were between 41-50 years of age. The BMI data of the patients shows that 20.3% of the patients were in normal weight, on the contrary, 44.9% were overweight (25 kg/m2 to 29.9 kg/m2). According to the pathology results of the patients, 63% (n=87) were serous, 31.9% (n=44) mucinous, 5.1% (n=7) endometrioid type borderline ovarian tumors. Spontaneous pregnancy was observed in 31% (n=18) and pregnancy as a result of assisted reproductive techniques in 5.2% (n=3) of the patients who underwent fertility preserving surgery. According to the results of the study, it is observed that there is a statistical relationship between recurrence and fertility preservation. Recurrence was observed in 2.5% (n=2) of the individuals whose fertility was not preserved while recurrence was observed in 24.1% (n=14) of individuals whose fertility was preserved. Although it was observed that recurrence increased in patients who underwent fertility preservation surgery, it allowed pregnancy to be achieved at a rate of approximately 36%.
Conclusion: Since patients with borderline ovarian tumours are younger than patients with invasive ovarian cancer, fertility-sparing surgery is becoming increasingly important.

Climatic factors determine the amount and distribution of atmospheric water received at the land surface while the land cover conditions determine the partitioning of this water into different hydrological components and ultimately the catchment surface water yields. This study assessed the effects of deforestation of a tropical catchment on surface water yields to address fluctuating flows of the rivers emanating from Mau Forest, the largest water tower in Kenya. Sondu basin traverses Southwest Mau Forest covering an area of 3500 km2. The main channel in the basin flows in a southwest direction into Lake Victoria in an altitudinal range of 2900 to 1130 m a.s.l over a length of 173 km. Different deforestation scenarios over the basin were integrated with climate data to form inputs to a hydrologic model, Soil and Water Assessment Tool (SWAT). Using model outputs, the effects of deforestation on annual and seasonal surface water yields, represented by changes in streamflow volumes under different deforestation scenarios, were evaluated. Deforestation scenarios were derived from a supervised classification scheme of time series of LANDSAT images (1970-2020) to show deforestation trends. Effects of deforestation on the catchment water-yielding capacity were estimated as the ratio of the difference between simulated yields under different deforestation scenarios and those simulated under the pre-deforestation scenario of the 1970s decade. Results show that forest cover declined by 21% and a corresponding growth in land under agriculture by 26% in the period 1970-2020. The decline in forest coverage resulted in an increase in the annual surface water yields of about 23% (from 152 to 187 MCM/year) throughout the period of study. This implies that there is less recharge of groundwater due to decreased infiltration and subsequent storage leading to lower flows during the dry seasons and increased flood frequencies in the basin during the wet seasons. The study has therefore, demonstrated that deforestation has reduced the stability of Mau Forest as a water tower and conservation of the forest will enhance its water-holding capacity thereby ensuring a stable water supply to rivers emanating from it as a way of combating floods and low flows in the basin. The resultant impacts on environment and society are displacements from floods and destruction of properties.
REFLEXÕES SOBRE ALFABETIZAÇÃO EM LÍNGUA DE SINAIS E LITERATURA EM LÍNGUA DE SINAIS, COM REFERÊNCIA AO QUADRO EUROPEU COMUM DE REFERÊNCIA PARA LÍNGUAS
Authors: Monte Maria Maria Tagarelli De
Published: June 2024

A definição de alfabetização evoluiu de sua definição original como uma habilidade cognitiva em relação a textos escritos. Após o aumento do estudo do multilinguismo e da forma que o texto escrito pode assumir, novas abordagens teóricas evoluíram para incluir outras formas ou alfabetizações, como multiliteracias, multimodalidade, alfabetizações reais, materialidade e afeto (Papen, 2023). Da mesma forma, as ferramentas educacionais e as estruturas linguísticas, como o Quadro Europeu Comum de Referências para Línguas (CEFR), evoluíram para incluir diferentes formas de intenção de conteúdos que visam transmitir valores e ideias socioculturais. Este artigo reflete sobre o que torna a alfabetização em língua de sinais em um contexto em que a literatura de referência é a literatura sinalizada, que vive e prospera junto com a literatura escrita. Nesse contexto, uma inclusão real dos surdos e de sua cultura de sinais deve considerar os conteúdos em sinais gerados pela comunidade de sinais e encontrar novas maneiras de incluí-los na educação das crianças surdas.

ALFABETIZAÇÃO EM ASL E DESENVOLVIMENTO DO PENSAMENTO CRÍTICO
Authors: Gibson Heather , Byrne Andrew
Published: June 2024

A maioria das definições de alfabetização, tanto históricas quanto contemporâneas, define-a como o conjunto de habilidades necessárias para aprender e trabalhar dentro das necessidades básicas da vida cotidiana (Lankshear & Knobel, 2006; Lemke, 2004, conforme citado em Korhonen, 2010). Até mesmo a Organização das Nações Unidas para a Educação, Ciência e Cultura (UNESCO) define a alfabetização informacional como “um contexto de capacitação, como as habilidades e capacidades de recepção crítica, avaliação e uso da informação na vida pessoal ou profissional das pessoas” (Frau-Meigs & Torrent, 2009, conforme citado em Korhonen, 2010, p. 218). No entanto, essas definições não capturam totalmente a alfabetização como as habilidades necessárias para a vida cotidiana dentro e fora do trabalho ou aquelas que promovem o desenvolvimento do pensamento crítico. Mais especificamente, essas definições não se aplicam explicitamente à alfabetização na Língua de Sinais Americana (ASL). Até o momento, a pedagogia de alfabetização bilíngue em ASL tem dado pouca atenção à definição de alfabetização em ASL e a uma compreensão completa de como ela está inserida nas práticas culturais e sociais. O foco tem se concentrado mais no currículo de ASL, nas práticas e estratégias de ensino, na avaliação de ASL ou em suas conexões com a ASL como idioma de estudo. Este artigo se concentra na definição abrangente de alfabetização em ASL e nos diferentes componentes de como a língua e a cultura1ASL estão conectadas ao desenvolvimento do pensamento crítico e ao uso de habilidades metalinguísticas e metacognitivas, como estratégias de compreensão e construção para decodificar, compreender, avaliar e refletir sobre trabalhos de alfabetização e textos em ASL, incluindo trabalhos de mídia em ASL. Nesse sentido, a alfabetização em ASL é vista como algo maior do que a definição das habilidades necessárias para o trabalho e o estudo, estendendo-se às habilidades necessárias para a vida. Além disso, este artigo ilustra como o aprendizado da alfabetização em ASL está ligado às inter-relações entre a criança, a casa, a escola, a comunidade ASL e a comunidade global.

Published: June 2024

A discussão sobre alfabetização em línguas de sinais bem como a literacia familiar para crianças ouvintes filhas de pais surdos (CODA - Children of Deaf Adults), que é uma área de estudo ainda incipiente. Nos poucos currículos de língua de sinais existentes, é dada atenção às línguas de sinais como primeira e/ou segunda língua das crianças surdas, enquanto há pouca discussão sobre a língua de sinais de CODA e suas habilidades bilíngues bimodais. Tal discussão nos traz indagações sobre as possibilidades de que as línguas de sinais estejam no currículo da escola para estas crianças ouvintes para além das crianças surdas. Para esse fim, este artigo apresenta quatro narrativas das infâncias de CODA que compartilham a sua língua de sinais como língua de herança, discutindo sobre alfabetização em língua de sinais e literacia familiar. Discutimos também a vinda ao mundo pela língua ancestral de seus pais surdos e de como cada família é uma geração única, sendo perpetuada por outras famílias e cada história contada, faz a língua viva e presente em outras famílias. O artigo enfoca as práticas de aprendimentos das línguas de sinais por crianças ouvintes filhas de pais surdos

Atherosclerosis and relative cardiovascular complications remain the main reasons for death worldwide. This study stimulated atherosclerosis in C57BL/6J mice using P-407 via intraperitoneal injection, and treatment with Andrographolide (AGP) (15, 30 and 45 mg/kg BW) was carried out for six weeks. The heart and aorta were harvested after six weeks and assessed using Enzyme-Linked Immunosorbent Assay (ELISA) and histological studies. The results demonstrated that the treatment with AGP reversed the effects of P-407 induced atherosclerosis. The doses of AGP correlated with the reduction of atherosclerosis biomarkers, and a high dose (45 mg/kg BW) was the most significant dose. The Low-Density Lipoprotein (LDL), Triglycerides (TG), and Atherogenic Index (AI) were significantly reduced by the AGP treatment. The histological results showed a reduction in inflammation, fibrosis and hypertrophy in the heart tissues of the groups treated with AGP compared to the disease control. In addition, AGP treatment significantly decreased Reactive Oxygen Species (ROS) and the inflammation marker (NF-kB). Furthermore, the AGP-treated groups showed typical morphological characteristics of the aorta, while the disease control cells were highly affected. The results demonstrated that AGP is highly recommended as a natural treatment to reduce the symptoms of atherosclerosis by reducing oxidative stress and inflammation.

Published: June 2024

The biodiesel is currently produced mainly from edible oils as feedstock, generating glycerol as a by-product. The use of glycerol as a carbon source for oil production by oleaginous yeasts contributes to the development of alternative routes of oil production in the context of the circular economy. Therefore, this study aimed to select oleaginous yeasts capable of producing oil in culture media containing glycerol as a carbon source. A total of 10 yeasts capable of assimilating glycerol as carbon source were evaluated for their ability to produce lipids in a glycerol culture medium to select a promising oleaginous yeast. Herein, the isolate CA8 was selected as the best lipid producer from glycerol considering the achieved values of lipid content (%), lipid titer (g/L), and biomass (g/L). This isolate was taxonomically identified as Meyerozyma guilliermondii and designated as Meyerozyma guilliermondii UFV-2. Since the C: N ratio notably influences lipid production by oleaginous yeasts, the effect of different C:N ratios on biomass production, lipid content and lipid titer were evaluated. The highest values of biomass formation, lipid content, and lipid titer, recorded in a C: N of 150:1, were 6.77 g/L, 25 % (w/w), and 1.71 g/L, respectively recorded. The lowest biomass formation 4.67 g/L was recorded in a C: N ratio of 75:1. Taken together, these results indicate that M. guilliermondii UFV-2 displays the potential to produce lipids from glycerol, opening perspectives for further studies that aim to optimize the production parameters.

Proteus species are rod-shaped, Gram-negative bacteria that cause opportunistic infections in the urinary tract and occasionally in the gastrointestinal tract.  They are implicated in infections like cystitis and pyelonephritis, particularly in immunocompromised individuals, and are frequently present in cases of asymptomatic bacteriuria.  Herein, we aimed to investigate the co-occurrence of extended-spectrum beta-lactamase (ESBL) enzyme production and multidrug resistance (MDR) among Proteus spp. Isolated from patients attending selected hospitals in Northeastern Nigeria.  A total of 1,500 clinical samples from consenting patients across six states in the Northeastern region of Nigeria were collected.  The samples were cultured on Blood agar, and growth resembling that of Proteus species were again subcultured onto MacConkey agar to obtain discrete colonies, further confirmed using biochemical tests.  Antibiotics susceptibility test was carried out for all isolates using the Kirby-Bauer disc diffusion method, coupled with a screening of the production of extended-spectrum beta-lactamase using the Combined Disc Diffusion Method.  Of the 1500 samples collected, 144 yielded positive growth for Proteus spp., resulting in a prevalence rate of 9.60%.  Among these Proteus isolates, three species were identified, with Proteus mirabilis (90.97%) being the most abundant, followed by Proteus vulgaris (8.33%) and Proteus penneri (0.70%).  The Proteus isolates displayed significant resistance to β-lactam antibiotics, with a Mean ± SD of 96.64 ± 22.73.  A substantial portion of the Proteus spp. Isolated exhibited multidrug resistance (87.89%), with Proteus mirabilis (82.27%) being the most prevalent MDR species.  Moreover, about 71.0% of the Proteus spp were ESBL producers, with Proteus mirabilis (64.54%) being the most predominant.  Furthermore, 67.38% of all isolates exhibited MDR and ESBL production, and Proteus mirabilis (62.41%) was the most significant among the three Proteus species.  These findings highlight the occurrence of multidrug resistance and ESBL production among Proteus spp. in Northeastern Nigeria, with Proteus mirabilis particularly noteworthy.  This information is crucial for guiding clinical decision-making, especially in managing infections caused by multidrug-resistant and ESBL-producing Proteus strains.

In response to the escalating concerns surrounding antibiotic resistance and associated side effects, interest in plant extracts and bioactive compounds derived from medicinal herbs has been resurgent. This study investigates the Phytochemical Screening, Gas Chromatography-Mass Spectrometry (GCMS) Analysis, and Antibacterial Activity of Moringa oleifera Leaf Extracts against clinical isolates. Utilizing aqueous and ethanolic extractions, the study determined the yield percentages as 16.25% and 7.14%, respectively. Phytochemical analysis revealed the presence of alkaloids, tannins, flavonoids, glycosides, steroids, terpenoids, and saponins in both extracts, with the absence of phenol. The antibacterial activity was assessed using the agar well diffusion method, showing inhibitory effects against the tested isolates. The ethanolic extract exhibited superior antibacterial activity, with a maximum zone of inhibition (17mm) against Pseudomonas aeruginosa at 800mg/ml. The aqueous extract demonstrated a maximum zone of inhibition (12mm) against the same bacterium at the same concentration. Comparative analysis with standard antibiotics revealed competitive inhibitory effects, especially against Staphylococcus aureus and Pseudomonas aeruginosa. Furthermore, GCMS analysis identified sixteen phytochemical compounds in the ethanolic extract and eleven in the aqueous extract. The findings underscore the significant antibacterial potential of Moringa oleifera extracts, particularly against Staphylococcus aureus and Pseudomonas aeruginosa. The GC-MS results provide crucial insights into the bioactive chemical profile, supporting the potential therapeutic applications of Moringa oleifera in combating various infections. This study contributes valuable knowledge to exploring alternative treatments amid growing antibiotic resistance concerns.

Full Abstract
Many microorganisms are capable of producing Exo-polysaccharides (EPS) while utilizing simple sugars and hexoses. These EPS found applications in various fields, such as agricultural biotechnology, pharmaceuticals, textiles, and food industries. However, there is a lack of studies on EPS-elaborating bacteria that can utilize pentoses like xylose. Therefore, the utilization of alternative carbon sources for EPS production has become a focus of recent research. This study aimed to prospect bacteria that can utilize xylose for EPS production. Samples from agricultural soil, dump sites, saline soil, cement-contaminated soil, fresh cow milk, cow dung, and yogurt were serially diluted and cultured in a salt-based medium with xylose as the primary carbon source. Slimy and mucoid colonies were selected as potential EPS-producing isolates and identified morphologically and biochemically using the VITEK 2 Automated identification system. The quantification of EPS production by these isolates was conducted through submerged fermentation with xylose as the sole carbon source. The mean heterotrophic bacterial count of xylose-utilizing bacteria ranged from 2.1x106 CFU to 3.5x108 CFU per gram of the samples analyzed. The slimy and mucoid colonies were identified as members of the genera Staphylococcus, Enterobacter, Kocuria, Klebsiella, Enterococcus, Serratia, and Burkholderia. The quantities of EPS produced by the isolates ranged from 0.04 g/L to 2.0 g/L, with E. cloacae D1, E. cloacae D2, K. oxytoca D2, and K. oxytoca G1 elaborating the highest amount of EPS. Bacterial isolates capable of utilizing xylose for EPS production were obtained from various sources, showing potential for further optimization
