Thrombocytopenia is a recurrent hematological disturbance in pregnancy. In pregnant women with thrombocytopenia, the risk of excessive bleeding during or after child-birth is high, particularly when they require a cesarean section, other surgery during pregnancy, labor or in the puerperium period. The objective of this study was to assess the prevalence of thrombocytopenia among pregnant women attending antenatal care service at Tripoli University Hospital, Libya. A cross-sectional analysis was used to determine the prevalence thrombocytopenia in pregnant women attending prenatal care services from July to December, 2020 at Tripoli University Hospital. A structured pretested questionnaire was used to obtain socio-demographic data, nutritional factors, obstetrics and gynecological factors, history and clinical conditions. Venous blood samples were collected for platelet count and other platelet parameters, which determined by using Sysmex automation. A total of 72 participated women; about 40%, 35% and 259% of the participants were in the third, second and first trimester, respectively. The mean number of children that women have was 2, with 2.7% having just one child and 47% having three or more children. This study concluded that the prevalence of thrombocytopenia and mostly with mild form is 8.3% and as being greater among pregnant women living in rural areas. Health care providers should do thrombocytopenia test regularly for every pregnant woman in order to prevent excessive bleeding during pregnancy, especially whom living in rural areas.

The primary objective of this study is to conduct a comprehensive analysis of the relationships between liquid- ity (LIQ), capital structure (LEV), and fnancial performance (FIP). Additionally, we seek to investigate the indirect efect of liquidity (LIQ) on fnancial performance (FIP) by examining the intermediary role of the capital structure (LEV) of non-fnancial-listed companies in the Vietnamese stock market. This study utilizes PLS-SEM with a robust sample of 644 non-fnancial-listed companies in the Vietnamese stock market. The fndings suggest that liquidity positively infuences fnancial performance but negatively impacts capital structure. Conversely, capital structure negatively afects fnancial performance. Thus, liquidity indirectly enhances fnancial performance through capital structure mediation. This research result can provide suggestions for non-fnancial enterprises in making fnancial decisions to increase fnancial efciency by increasing the holdings of highly liquid assets to prevent risks and take advantage of new investment opportunities in the future. In addition, increasing the holding of highly liquid assets also reduces debt pressure and reduces interest costs, thereby increasing fnancial efciency. Our research shows that the relationship between economic factors is extremely complex; specifcally, our research shows the true nature of the positive impact of liquidity on fnancial performance, including direct positive efects and indirect positive efects through capital structure. In addition, our research results also show that non-fnancial enterprises that want to increase fnancial efciency need to pay attention to revenue growth, and non-fnancial companies with larger total assets (size) will have more advantages in increasing fnancial performance.
This study was aimed at investigating the extent to which signage and ICT facilities correlate to the utilisation of information resources in federal university libraries in South-South zone of Nigeria. The correlational research design was adopted for the study. Three research questions were answered while three hypotheses were tested. The population of the study comprised 32,190 registered library users for the 2017/2018 academic session and 776 library staff from six federal university libraries in south-south zones of Nigeria. The sample size for the study was 3,219 registered library users and 310 library staff representing 10% and 40% of the population respectively. A two-stage sampling technique of stratified and simple sampling techniques was used to select the sample size. Two Sets of instruments titled; “Signage and Information and Communication Technology Facilities Questionnaire (SICTFQ)” for the students and “Utilization of Information Resources Questionnaire (UIRQ)”were used for data collection. Face and content validity was ensured by three experts. The two instruments yielded reliability coefficients of 0.81 and 0.87 respectively with the use of Cronbach Alpha. Mean was used in answering research questions while Regression was used in testing the null hypotheses at 0.05 alpha level. It was found that to a great extent signage relates to the utilisation of information resources while information and communication technology facilities is the vice versa. Based on the findings, it was concluded that jointly, signage and ICT facilities are significant correlate to the utilisation of information resources in federal university libraries in South–South zone of Nigeria. It was therefore recommended among others that library management should improve on the provision of signage by ensuring that well-designed signage suitable for the 21st century is placed at strategic location to guide library users on the utilisation of information resources in federal universities libraries in South-South zone of Nigeria.
This study evaluated power system reliability and frequency tolerance requirements for the management of critical-care medical devices at the Niger Delta University Teaching Hospital (NDUTH). The analysis focused on two primary parameters: voltage stability and frequency deviation, to determine the conditions necessary for sustaining Intensive Care Unit (ICU) ventilator uptime and neonatal incubator performance. Voltage and frequency data were collected at regular intervals over a five-month period and analyzed using reliability modeling and MATLAB-simulated multidimensional surface plots. Results indicated that ICU ventilator uptime stabilized at 96.1% when system voltage remained within the 208 and 222V band under controlled load conditions. Neonatal incubator reliability, however, declined sharply when frequency deviation exceeded 0.11Hz, activating maintenance thresholds. Extended voltage dips below 185V and frequency excursions above 0.12Hz were associated with increased likelihood of device failure and elevated corrective maintenance demand. The findings underscored that uninterrupted operation of critical-care devices depends on integrating voltage and frequency reliability metrics into equipment management protocols as conclusion. Accordingly, it was recommended that NDUTH management implement continuous power-quality monitoring, enforce maintenance protocols guided by operational thresholds, and strengthen redundancy measures. These actions will enhance device reliability, reduce service interruptions and support safer, more consistent delivery of critical care in the hospital setting
Background: Gestational hypertension (GHTN) is defined as a new rise in blood pressure (BP) ≥140/90 mm Hg, presenting at 20 weeks gestation without significant proteinuria. Worldwide, 4.4%-15% of all pregnancies are complicated by HTN. The aim of this study was to determine the incidence of GHTN among pregnant women in Enugu State, Southeast Nigeria with a view to improving and strengthening antenatal services in the State to help reduce the proportion of maternal mortality and fetal outcomes attributable to GHTN and reduce the overall prevalence of HTN in the country. Methods: Records of BP, biodata and laboratory investigations (urinalysis, full blood count) of women who attended antenatal clinics in six selected state hospitals (2006-2015) were examined. Data were analyzed as proportions, t-test, ANOVA and Pearson product moment correlations using Maxstat (version 3.60) statistical software. Results: The overall incidence of GHTN was 5.9% with annual fluctuations with peaks in 2010 and 2014. There were significant differences in incidence among the age groups (<20>35 years) (p<0 p=0.0016).>35 years) and GHTN (r=0.932, p=0.0069). Between parity and GHTN, there was also positive, strong and significant correlation (r=0.813, p=0.0491). Conclusions: With an incidence of GHTN at 5.9%, there is need to improve and sustain adequate antenatal services in order to help reduce the proportion of the country’s maternal mortality attributable to hypertensive disorders of pregnancy.

This study discusses credibility of both the traditional and social media from the audience perspective. Numerous definitions and conceptualisations of media credibility are either source or medium based but there are also numerous measurements made on the concept that gave rise to varied findings. An attempt was made to associate the concept of credibility with media exposure, postulating that the greater use of media would mean greater credibility. Two studies were made involving a total of 4095 respondents with 1544 questionnaires distributed in April 2019, and 2551questionnaires in January 2018 to investigate the concept of credibility and its correlate with media use. The first period was before the General Elections but the April 2019 study was made after the May General Election giving an idea how credibility could have changed under a new government. The results of this study revealed that Malaysians perceived the traditional media, including TV, radio, and newspapers, were more credible than the new media (internet, online news portals, Facebook, and Twitter). TV was perceived to have the highest credibility, while Twitter, the lowest credibility. The social media suffered low credibility due to the surrounding discussions on fake news, false information, and post-truth issues. The sources of content in the traditional media are mostly known or verified, unlike that of the new media, thus paving for the poor evaluation of credibility of the new media.
Bacteria that colonize plant roots and enhance the plant growth are denoted as Plant Growth Promoting Rhizobacteria (PGPR). The objective of this study is to isolate and identify Oryza sativa indigenous rhizobacteria and test for its, bio-control and various plant growth promoting traits under in-vitro condition. Nine rhizobacterial colonies isolated from healthy rice rhizosphere soil were screened for bio-control activity against rice pathogen Helminthosporium oryzae (rice brown spot) and Rhizoctonia solani (sheath blight) by performing dual culture method. The isolate B9 showed maximum antagonism against R. solani (73.7%) followed by isolate B2 (51.2%), isolate B1 (47.5%) and isolate B5 (42.5%) with different range of mycelial inhibition. Among nine rhizobacterial isolates tested, the growth of pathogenic fungi H. oryzae was only inhibited by the isolate B9 (20.5%). The isolates B1, B2, B5 and B9 exhibited maximum bio-control activities were further screened for different PGP traits, such as Phosphate (P) solubilization, Indole-3-Acetic Acid (IAA) production, Hydrogen Cyanide production (HCN) and extracellular enzyme production under in-vitro condition. The isolate B9 revealed the maximum P solubilization efficiency (99 SE), 45 μg/ml of IAA, HCN, amylase and cellulase production in maximum amount. The isolate B9 exhibited maximum bio-control, and PGP traits were identified by morphological and biochemical characterization and it was identified as Bacillus subtilis. In pot experiment, the rice seeds treated with B. subtilis exhibited significant shoot and root biomass when compared with un-inoculated rice and fungus-infected rice. This study highlighted the beneficial properties of native PGPR’s on growth promotion of rice and it could be formulated as bio-control as well as plant growth promoting agent, to reduce the application of chemical fertilizers in agricultural lands.
Abstract __ Considering the size and relevance of coffee industry to the Ethiopian economy this work presents the design, prototype development, analytical and numerical simulation as well as experimental investigation on an active solar coffee dryer. The solar collector and dryer system configuration has been optimized for minimal pressure drop by incorporating guide vanes and minimizing flow separation tendency using numerical simulation on ANSYS. The effect of air mass flow rate on optimal depth of collector, temperature rise and pressure drop were characterized including the effect of variation in solar insolation using CFD approach. By comparing different dryer configurations based on pressure drop and air flow uniformity, a new dryer configuration prototype was developed. In addition, thermal performance of the solar air heater was evaluated experimentally at three different airflow rates on a collector with corrugated absorber plate and another collector with flat absorber plate. High collector outlet temperature and efficiency were observed in a collector with corrugated absorber plate. The effect of depth of grain, moisture content on wet basis, airflow rate and humidity of air were explored for parametric sensitivity vis-à-vis drying time. Within 5 hours, coffee bean dried from 29% moisture content to 12.3% on a clear sunny day and within 7hours from 19% moisture content to 11.1% on a partially overcast day. Average thermal efficiency of the dryer was found to be 50.5% for clear sunshine day and 36.9% for partial overcast day. A good agreement has been observed between the experimental results and the CFD temperature rise predicted output with a deviation of 7.5%. Analytically predicted drying time compared with experimentally measured drying time within a 12.9% deviation. The cost -to-benefit analysis with a comparative assessment on traditional mode of coffee drying has been done and the payback period is found to be 1.03 years with significant benefits.

In this article, we establish the exact wave solutions of the Boussinesq equation and the (2 + 1)-dimensional extended shallow water wave equation by applying the new generalized (G'/G)-expansion method. When the condition of the fluid is such that the horizontal length scale is much greater than the vertical length scale, the shallow water equations are mostly suitable. In Ocean engineering, Boussinesq-type equations are commonly used in computer simulations for the model of water waves in shallow seas and harbors. We explained the new generalized (G'/G)-expansion method to seek further general traveling wave solutions of the above mentioned equations. The traveling wave solutions attained by this method are exposed in terms of hyperbolic, trigonometric and rational functions. The shape of the obtained solutions are bell shaped soliton, kink soliton, singular kink soliton, singular soliton, singular periodic solution and compaction. This method is very influential mathematical tool for extracting exact solutions of NLEEs which frequently arise in mathematical physics, engineering sciences and many scientific real world application fields.
Elevated arterial blood pressure is the most important public health problem in developed countries. It often leads to lethal complications if left untreated. Brewer's yeast is celebrated for its various beneficial effects, including a possible hypotensive effect. Thus, the anti-hypertensive effects of brewer’s yeast were investigated. The hypertensive model was done by a once-weekly intraperitoneal injection of dexamethasone at a dose of 25 mg/kg combined with drinking a 1.0% sodium chloride solution containing 0.2% KCl and 2.0% glucose for six weeks. The blood pressure was measured by the rat carotid artery cannulation preparation. Different doses of brewer's yeast dissolved in distilled water were injected into the internal jugular vein, with measurement of blood pressure at each time. To explore the mechanism of the hypotensive effect of yeast, the yeast cardiac effect was verified by the use of isolated perfused rabbit heart preparations using different antagonists. It was found that dexamethasone elevated systolic blood pressure to 178.3±11.6 and diastolic blood pressure to 133.3±16.6 from normal levels of 115.0±9.1 for systolic and 74.0±4.1 for diastolic. The gradual increase in intravenous yeast doses ranging from 0.05 to 0.40 effectively lowered systolic and diastolic blood pressure in rats with normal pressure, bringing them to approximately 80.0±05.6 mmHg for systolic and 40.0±3.5 mmHg for diastolic. While doses exceeding 0.04 resulted in a drop in systolic pressure to 60.0±3.9 mmHg, diastolic pressure became unrecordable. The administration of the 0.20 dose resulted in unrecordable blood pressure. In hypertensive rats, a decrease in blood pressure was observed with doses ranging from 0.60-1.0 mg, leading to a reduction to 110.0±2.8 mmHg for systolic and 52.0±9.9 mmHg for diastolic pressures. Doses exceeding 1.0 mg further lowered systolic and diastolic pressures to 20.0±3.9 mmHg. There was a mild increase in heart rate with no change in cardiac force of contraction. This effect was not mediated through beta, calcium receptors, or the histamine effect. The findings show that the yeast has a dose-dependent blood pressure-lowering effect. The mechanism of the chronotropic effect is possibly due to its direct action.

Pelvic inϑlammatory disease (Waram al-Rahim)is one of the most serious gynaecological infections of the upper female genital tract with the worldwide annual rate of 10-20/1000 women of reproductive age. The objective planned for the study was to evaluate the effect of Sharbat-e-Deenar in uncomplicated Pelvic Inϑlammatory Disease (uPID). A pre and post observational single group clinical study was carried out in the Department of IlmulQabalatwaAmrazeNiswan, National Institute of Unani Medicine, Hospital, Bengaluru. Diagnosed cases (n=30) of uPID were included in the study. Patients with complicated PID, history of antibiotic therapy within seven days of recruitment; delivery, abortion or gynecologic surgery within the last 30 days, systemic diseases, malignancies, pregnancy & lactation were excluded. Sharbate-Deenarconsists of Poste baikhekasniandTukhmekasni(Cichorium intybus Linn.), Gulesurkh (Rosa damascene mill.), Tukhmekasoos(CuscutarelexaRoxb.) and Rewandchini (Rheum emodiWall. ex Meissn) were administered orally in a dose of 20 ml twice daily for 14 days. Outcome measures were 30-70% clinical improvement in Visual Analogue Scale (VAS) score for lower abdominal pain and McCormack Pain Scale (McPS) score for abdominopelvic tenderness and White Blood Cells (WBCs) count <10 on saline microscopy of discharge. Data were analyzed using paired Student ‘t’ test, Wilcoxon Signed rank test and Paired Proportion test.Clinical improvement of 30-70% in McPS and VAS score was achieved in 96.7% (p<0.001**) and 93.3% (p<0.001**) patients respectively. WBCs count <10 on saline microscopy of discharge was achieved in 70% patients (p<0.001**).Sharbat-e-Deenarwas effective in improving the sign & symptoms of PID due to its anti-microbial, anti-inϑlammatory, antispasmodic and anti-oxidant properties. No adverse effect of the research drug was encountered during the study. Hence, Sharbat-e-Deenar serves as an effective alternative in patients with PID, proving the research hypothesis.
In order to perform its basic function of safeguarding life and property, every power system needs an earthing profile that is effective and efficient. Recent studies carried out in the Niger Delta show that its soil is corrosive and frequently attacks the earthing system thereby rendering same ineffective thus posing a great danger to human life and property. This paper reviewed several scholarly literature related to the study for causes of earthing system failures and found that corrosive soils, poor workmanship, wrog choice of earthing materials, lack of maintenance etc. were dominant factors hindering effective and sustainable earthing system in the Niger Delta. The paper, therefore, recommends the regular use of experienced workmen, choice of quality earthing materials, periodic testing, inspection and maintenance as strategies to improve the earthing condition in the area.
Background: From the public health point of view, the microbiological properties of domestic water supply are the most important parameters of domestic water supply because of the propensity for microbial water-related diseases. In Enugu State, statistics have shown that reported cases of waterborne diseases (including typhoid fever) have been on the increase since 2003. The aim of the study was to determine the bacteriological qualities of domestic water supply and prevalence of typhoid fever in five communities of Enugu State in connection with the rising incidence of typhoid fever in the state. Methods: This was a cross-sectional study of sources of domestic water supply and prevalence of typhoid fever in five rural communities of Ezeagu Local Government Area. 297 copies of structured questionnaire, 10 grab water samples analysed using the membrane filtration method and 227 blood samples collected for Widal test were used to generate the data for the study, analysed as frequency distributions, t-test of means difference and Pearson product moment correlations using MaxStat (version 3.60) statistical software. Results: 2 (40%) of the 5 communities complied with the WHO standard for faecal coliform counts. Prevalence of typhoid fever was high in all the communities (71.4%-100%). Only faecal coliform counts correlated positively and strongly (r=0.69) with prevalence of typhoid fever. Conclusions: Since faecal coliform counts correlated positively and strongly (r=0.69) with prevalence of typhoid fever, improving the bacteriological qualities of domestic water supply may help to reduce the prevalence of typhoid fever.
ABSTRACT “Numbers are the highest degree of knowledge. It is knowledge itself.”- Plato “The world is built on the power of numbers.” Pythagoras “Everything around you is numbers.” Shakuntala Devi. The date, we were born on, was not an accident. Each number in our date of birth is connected with certain energies and vibrations. Similarly, each and every letter in our name (first as well as full name) also has particular frequency, energies and vibrations. The combined and correlated energies of numbers and letters of an individual reveal about the past, present and future. The careful study of these universal divine energies can reveal, who you are, why you are here, where are you going and how will you get there. In other words what is your personality, nature, thinking, and what is your future in terms of family career relationships and finances etc. In this study, an attempt has been made to analyze -How certain patterns of name numbers and date of birth related core numbers can emerge as a directional guide for an individual to choose any specific career/profession (by studying the patterns of over 1100+ date of births and names of the Engineers cum Arbitrators).
The current study used the chick emesis model to explore the anti-emetic effect of the methanolic extract of Acalypha ornata Hochst—roots. Emesis was induced by the oral administration of copper sulfate to male chicks. Acalypha ornata root extract (150 mg/kg orally) showed an anti-emetic effect and was compared with the reference drug chlorpromazine
The blunted nose cone with and without a sharp aerospike and an aerodisk of various diameters and lengths are investigated numerically in detail in the current study at a hypersonic Mach number of 10. The aerodisk diameter is described as d/D ratios such as 0.2, 0.4 and 0.6, and the length of the aerospike is represented as the L/D ratio of 1, 1.5 and 2. The main objective of the research is to examine the aerodynamic properties of blunt noses with and without aerodisks and aerospikes, as well as the influence of shock production over the model. The design of blunted nose cones with aerodisk was made up using CATIA and numerical investigation was performed on the ANSYS Fluent. The turbulence model of SST k-omega was considered for study. The current study revealed that shock patterns drastically varied nearer to the nose cone model at L/D ratio 2 and variation of drag reduction occurred due to the increase in d/D ratio and aerospike and also flow pattern over the model was clearly investigated.
