The Benefits of Enterprise Data Warehouse Implementation in Cloud vs. On-premises
Authors: Golec Darko , Strugar Ivan , Belak Drago 
Published: January 2022

When we think about running enterprise applications on-premises, enterprises do two things for their servers, databases, and storage. Enterprises provision for peaks and put a lot of infrastructures to handle peak demand, although a lot of this capacity is not used at normal times. The other thing is a few instances that each application needs to have, typically between five and six. Multiplying this number by many times due to various applications causes a lot of costs and creates capacity that is not used. For such reasons, the enterprise applications in the cloud seem reasonable. In the cloud, two things are possible again. Instead of overprovisioning for peaks, enterprises can scale the capacity on on-demand and spin up instances on demand. This means a certain amount of cost-saving by running at a normal level instead of overprovisioning. In this paper, various factors will be considered, and the benefits for enterprise data warehouse implementation in the cloud vs. on-premises will be stated.

Under-Five Mortality Causes and Prevention
Authors: Tekin Mehmet 
Published: January 2022

The under-five mortality rate (U5MR) represents children who die before reaching the age of 5 per 1000 live births. It is directly related to the development and economic income levels of countries. For this reason, high rates are observed in low- and middle-income countries (LMICs). The neonatal period deserves more attention as the decline in mortality rates has recently stalled. The most common causes of death under 5 years old are acute respiratory infections, diarrhea, malaria, and birth complications. Although neonatal disorders and birth complications have recently come to the fore, among these reasons, deaths due to infections are still high in LMICs. The crucial topics in prevention are perinatal care and vaccination. Apart from these, access to medicine, food, and clean water is essential in preventing deaths under 5. For preventive services to achieve their goal, these services must reach everyone. Ending preventable child deaths is only possible by improving access to well-equipped healthcare professionals during pregnancy and childbirth, life-saving interventions such as vaccinations, breastfeeding and the provision of low-cost medicines, and access to water and sanitation, which are now lacking in low-income countries.

Published: January 2022

Gallbladder polyps (GBP) are defined as developed masses inside the wall of the gallbladder; most of them (90%) are nontumor lesions. Abdominal ultrasound is the main and the first line radiological modality for their diagnosis and their risk lamination. We conducted a 12 year retrospective study between 2009 and 2020, which included patients who had preoperative transabdominal ultrasonography showing gallbladder polyps and had undergone cholecystectomy, and for whom postoperative pathology results were available, as well as patients who had at least one polyp discovered on the histopathological exam and who were not determined preoperatively. A total of 70 patients were identified. Preoperative diagnosis of vesicular polyp by ultrasound was carried in 82.9% of patients. The number of ultrasounds performed per person was 1.2 ± 0.47. The polyps’ size in mm was on average 6.14 ± 2.6 with extremes between 3 and 13 mm. On anatomopathological examination, a polyp was objectified in 33.3% of cases. In our series, abdominal ultrasound had a low sensitivity at 36.4%. We aim to provide the accuracy of abdominal ultrasound for the diagnosis of GBP, as a low-cost modality, and to evaluate the concordance of preoperative ultrasound imaging with postoperative pathology.

Authors: Suzzy Shitta Ndenum , Chukwudi Edemodu Alex , Gebreselassie Abtew Wosene , Abebe Tesfaye Abush 
Published: January 2022

African yam bean, an underutilized legume usually cultivated for its edible tubers and seeds, is known for its nutrition-rich qualities; however, the crop’s level of consumption is low. The underutilization of the crop could be attributed to several constraints, including long cooking hours of up to 24 hours. Cooking time is an important food trait; it affects consumers’ choices, nutrients content, and anti-nutrient conditions. Additionally, foods requiring long cooking hours are non-economical in terms of energy usage and preparation time. The prolonged cooking time associated with AYB places enormous limitations on the invaluable food security potentials of the crop. Therefore, the availability of AYB grains with a short cooking time could lift the crop from its present underused status. To efficiently develop AYB grains with reduced cooking time, information on the crop’s cooking variables is a prerequisite. This review presents available information on variations in cooking time, cooking methods, and processing steps used in improving cooking time and nutrient qualities in AYB. Likewise, the review brings to knowledge standard procedures that could be explored in evaluating AYB’s cooking time. This document also emphasizes the molecular perspectives that could pilot the development of AYB cultivars with reduced cooking time.

Introduction Few studies have addressed long-term quality of life related to residual snoring after adenotonsillectomy. The aim of this study was to compare scores from the OSA-18 questionnaire between children with residual snoring and non-snoring children two or more years after adenotonsillectomy.
Material and Methods The sample comprised 25 children divided into two groups, a group of 14 snoring children, and a control group of 11 non-snoring children. The OSA-18 questionnaire was applied to the volunteers. In the control group, it was completed by the caregivers of the children, while in individuals with residual snoring it was completed by the caregivers of children in the presence of a doctor or dentist. A statistical comparison was made using a generalized linear model.
Results The snorer group had a higher total OSA-18 score, and a higher score in all five domains compared to the control group.
Conclusion Children with residual snoring two or more years after adenotonsillectomy may have a worse quality of life compared to the control group.

Published: January 2022

Introduction Methamphetamine dependence is common in the world. Methamphetamine affects sleep architecture through changes in the monoaminergic activity of the brain. Limited studies investigated the sleep architecture in patients with methamphetamine dependence during prolonged abstinence. Therefore, this study investigated the sleep architecture of methamphetamine ex-users in the remission phase by polysomnography.
Material and Methods This was a cross-sectional study conducted during 2015-2017 in Mashhad, Iran. 12 methamphetamine ex-users in early full remission phase were selected from residential treatment centers through the convenient sampling method. The clinical interview was made to confirm the diagnosis and assess the inclusion and exclusion criteria. We performed urine dipstick tests to detect any relapses. Participants underwent a one-night polysomnographic evaluation, voluntarily. The collected data were analyzed by independent sample t-test and chi-square test, using SPSS-16. The level of significance was less than .05.
Results The mean total sleep time of participants was significantly lower than the total sleep period (333.6±79.1 vs. 403.0±52.9 minutes, respectively; p=0.001), leading to a significant low sleep efficiency (75.7±14.4%, p=0.047). Evaluation of rapid eye movement (REM) sleep showed a significant increase in the REM latency compared to the healthy population (p<0.001). Stages 1 and 3 of non-REM sleep were increased compared to the healthy population, too (p<0.001 and p=0.002, respectively).
Conclusion Former methamphetamine users continue to experience some long-term abnormalities in sleep architecture a few months after drug cessation

Developmental exposure to the DE-71 mixture of polybrominated diphenyl ether (PBDE) flame retardants induce a complex pattern of endocrine disrupting effects in rats
Authors: Ramhøj Louise , Mandrup Karen , Hass Ulla , Svingen Terje , Axelstad Marta 
Published: January 2022

Polybrominated diphenyl ethers (PBDEs) are legacy compounds with continued widespread human exposure. Despite this, developmental toxicity studies of DE-71, a mixture of PBDEs, are scarce and its potential for endocrine disrupting effects in vivo is not well covered. To address this knowledge gap, we carried out a developmental exposure study with DE-71. Pregnant Wistar rat dams were exposed to 0, 40 or 60 mg/kg bodyweight/day from gestation day 7 to postnatal day 16, and both sexes were examined. Developmental exposure affected a range of reproductive toxicity endpoints. Effects were seen for both male and female anogenital distances (AGD), with exposed offspring of either sex displaying around 10% shorter AGD compared to controls. Both absolute and relative prostate weights were markedly reduced in exposed male offspring, with about 40% relative to controls. DE-71 reduced mammary gland outgrowth, especially in male offspring. These developmental in vivo effects suggest a complex effect pattern involving anti-androgenic, anti-estrogenic and maybe estrogenic mechanisms depending on tissues and developmental stages. Irrespective of the specific underlying mechanisms, these in vivo results corroborate that DE-71 causes endocrine disrupting effects and raises concern for the effects of PBDE-exposure on human reproductive health, including any potential long-term consequences of disrupted mammary gland development.

Authors: Nwamaka Kanikwu Phoebe 
Published: January 2022

Introduction: Some couples do not have the gender of children they prefer which could result in physical, psychological, sexual, obstetric and several other consequences. The present study was conducted among men to determine their perception of gender preference and factors responsible for their gender preference.
Objective: To assess the perception of gender preference and factors responsible for gender preference among men.
Methods: A descriptive survey research design was adopted for the study. Proportionate stratified random sampling technique was used to select 143 out of 221 male Civil Servants from nine (9) different departments. The instrument used for data collection was a self-developed Questionnaire on Perception and Determinants of Gender Preference (QPDGP). The reliability of the instrument was established through the test-retest method using Cronbach’s alpha which yielded co-efficient of 0.82. Data collected were summarized using frequencies and percentages.
Results: The results showed that 90 (62.9%) men preferred male gender. For 79 (55.2%) men, the choice of gender was aimed at psychological satisfaction in marriage. Also, 77 (53.8%) preferred male children because they had better initiative, were easier to train 101 (70.6%), to allow for security of family inheritance 142 (99.3%) and continuity of family name 141 (98.6%). Some reasons given for female child preference were better ability to take care of younger ones 99 (69.2%), more supportive to aged parents 115 (80.4%) and being a reliable emotional support 88 (61.5%).
Conclusion: Male gender preference is strongly perceived among the men. It was recommended that reproductive health services be modified to allow male involvement.

Authors: Ogunmoyole Temidayo , Johnson Olaitan Daniel , Yusuff Adewale Akeem 
Published: January 2022

Aim: Globally, burden of liver and kidney diseases has been on the increase in recent times. The present study therefore investigates the hepatoprotective and nephroprotective potentials of unripe plantain Musa paradisiaca on CCl4-induced oxidative damage in albino rat. This was with the aim of providing a locally available and potent therapeutic alternative to the conventional drugs used in the management of liver and kidney diseases.
Place and Duration of Study: The study was conducted at the Department of Medical Biochemistry, College of Medicine, Ekiti State University, Ado Ekiti between July 2018 and January, 2019.
Methodology: Twenty-five adult male albino rats were placed into seven groups of 5 animals each. Group I animals received distilled water throughout the duration of the experiment, while group II were exposed to CCl4 only. Groups III, IV, V and VI received 3 ml/kg b.w of CCl4 intraperitoneally but were post treated with 50 mg/kg and 100 mg/kg of unripe plantain extract respectively while group seven were post-treated with silymarin by oral gavage. Animals were sacrificed for the excision of the liver and kidney. Activities of creatinine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), as well as levels of urea, uric acid, bilirubin and lipid profile were assessed. Tissue antioxidant level of reduced glutathione (GSH) and activities of antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT) were also determined.
Results: Exposure to CCl4 caused a significant derangement in lipid profile, resulting in the increase in serum triglyceride, total cholesterol and low density lipoprotein (LDL) while high density lipoprotein (HDL) level was diminished. Liver and kidney biomarkers (ALT, AST, ALP, CK, urea, uric acid and bilirubin were also significantly elevated in the serum relative to the control animals following exposure to CCl4. Activities of antioxidant enzymes in the serum were markedly inhibited by CCl4 exposure. Treatment with Musa paradisiaca extract caused a dose-dependent restoration of all biochemical parameters determined, while histopathological observation was in agreement with biochemical results.
Conclusion: These findings showed that Musa paradisiaca extract exhibited positive modulatory effects on the liver and kidney subjected to oxidative attack, hence, its potential usefulness in the management diseases associated with these organs.

Published: January 2022

The electrostatic induction mechanism, which superimposes charges on pesticide spray droplets, creates an impact on deposition and wraparound effect on leaf surfaces Smaller droplets have a higher capability to charge accumulation over the surface of the droplet as compared with larger droplets. This paper studied the effect of nozzle type (flat fan, hollow cone, and full cone nozzle), orifice area (1 and 1.5 mm2), and operating pressure (3-5kg cm-2) on spray droplet characteristics on soil bin. Water-sensitive papers were analysed by image analysis software to get the droplet characteristics. The smallest droplets of a hollow cone, flat fan, and full cone were 130, 142, and 279.76 µm respectively produced at 5kg cm-2 and orifice opening 1 mm2. With an increase of pressure droplet size and relative span was decreased for all selective nozzle. From the selected nozzles, the lowest relative span of 0.89 was found with a hollow cone nozzle at 5 kg cm-2 pressure and orifice size of 1 mm2. Among all the selected nozzles hollow cone nozzle produced the smallest droplet sizes and lowest relative span for all selected parameters.

Published: January 2022

The study was aimed at the in-vitro investigation of the antibacterial activity, antioxidant potential and bioactive compound isolation from ethyl acetate crude fraction of Laggera aurita (L. aurita) Linn. The crude fraction was tested against five gram negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhi, Proteus mirabilis) and three gram positive bacteria (Staphylococcus aureus, Enterococcus faecalis and Bacillus subtilis) using macro dilution technique. The antioxidant potentials were evaluated using two different but complementary methods namely ferrous ion chelating activity (FICA) and ferric reducing antioxidant potential (FRAP). Phytocompound isolation was carried out on low pressure open column chromatography. The crude fraction displayed moderate to significant activity against all tested bacteria exhibiting both bacteriostatic and bactericidal effects. The crude fraction showed Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) in the range of 62.50-250 µg/mL and 125-1000 µg/mL respectively. The crude fraction was bactericidal to all tested pathogens except E. coli. The fifty percent effective concentration (EC50) of EDTA standard and the ethyl acetate fraction were obtained as 10.87 μg/mL and 25.77 μg/mL respectively. Similarly the FRAP determinations for ascorbic acid and ethyl acetate fraction yielded 153.63 and 134.40 Fe2+ Equivalent per g of fraction indicating 80.06% and 70.61% FRAP units respectively. The isolated phytocompound coded LAE was obtained as a white crystalline solid with melting point of 136‐138°C and Rf of 0.56 in hexane: ethylacetate (6:4). The isolated compound was identified by spectroscopic data analysis from FT-IR, GC-MS, 1D and 2D NMR and in comparison with literature. The compound was identified as stigmasterol. The observed significant antibacterial and antioxidant properties demonstrated by L. aurita in this study validate its widespread use in traditional medicine. Therefore the study had shown that L. aurita contains bioactive principles and may serve as a source for potential antibacterial and oxidative stress therapeutic agents.
