The need for renewable energy sources in addressing global energy demands is growing, especially in Nigeria where electricity demand often exceeds supply. Solar photovoltaic (PV) systems have become a viable solution, with federal universities in Nigeria, as major electricity consumers, recognizing their potential. However, determining the right size of PV systems for individual faculties within these universities is a complex task. This study attempted to simplify this process by introducing an innovative approach to size PV systems in these faculties. The research method used the Extended Kalman Artificial Neural Network (EKF-ANN) and the Crow Search Algorithm (CSA) to enhance the accuracy of PV system sizing. Data was collected on the study site, load demand, weather conditions, system components, and operational control and systems models to establish sizing criteria. The study focused on the optimal size of a solar PV system at the Faculty of Law building, University of Port-Harcourt, and how to improve its accuracy. The results showed that using global solar insolation parameters, EKF-ANN predicted values for global temperature, flock size, and maximal iteration. This optimized system could generate surplus power for effective grid supply. The study found that the optimal size of the series-connected panels for the Faculty of Law building was 96, 83, 73, and 65 units, with corresponding insolation values ranging from 3.737 to 4.368 kW/m2. It was concluded that the combination of CSA and EKF-ANN in solar PV sizing is suitable for achieving optimal outcomes for energy storage and grid supply. Nonetheless, the study recommended additional investigation into real-time and grid-connected solutions to enhance the proposed approach's effectiveness.
During the last two decades, the concept of Fibre Metal Laminates (FMLs) has been evolved to find solution to the requirement of improving mechanical properties and reducing structural weight of elemental components of aircraft structures. In this work FML is prepared using Al 2024 by placing alternately with glass/carbon/aramid Fibres. From experimental results of FML shows greater advantage in mechanical properties then aluminium monolithic layer and this composite fibre laminates individual. The FMLs tested in this work were made of 3 layers of 2024 T3 aluminium alloy 0.28 mm thickness and fibre mats. The 5-3/2 laminates of size 300x300 mm with 3 mm thick were prepared using Vacuum Assisted Resin Transfer Moulding (VARTM) in cold compaction and test specimen were cut by using abrasive water jet machining as per ASTM Standards. The adhesion between fibre and metal layer will play a major role in strength of FML. By keeping this in consideration FMLs were prepared without blow holes and capable of withstanding delamination while preparing specimens through water jet and during various tests employed. The fracture surfaces of destructed specimens are studied with help Scanning Electron Microscope (SEM) image. Similarly, the numerical simulation of all the tests were done using Ansys APDL 10.0 Software. It is observed that aramid FML have substantially stronger in longitudinal directions. Hence, more priority given in this paper to investigate tensile strength and fatigue life of aramid FML.
Clinical microbiology serves as a partner to clinicians in the diagnosis and treatment of infectious diseases. Antibiotics are prescribed empirically before the availability of antimicrobial susceptibility testing data, especially when the patient's medical status could deteriorate by suspending the treatment. To investigate the impact of antimicrobial susceptibility testing on the management of outpatients with suspected bacterial infection in Libyan patients, a cross-sectional prospective study concluded on microbial microdroplet culture by including outpatients with suspected bacterial infection, who have done antimicrobial susceptibility testing. Thus, 53 Libyan patients with urinary tract infections and 14 Libyan patients with skin infections were included in this study. Before the availability of antimicrobial susceptibility testing data, 25 patients were appropriately treated while 42 patients were inappropriately treated. After the availability of antimicrobial susceptibility testing data, the number of appropriately treated patients increased to 57 patients. Thus, antimicrobial susceptibility testing improved the management of 41 patients by discontinuing an unnecessary antibiotic in four patients, starting necessary antibiotic therapy in 18 patients, and changing to more appropriate antibiotic in 19 patients. However, the antimicrobial susceptibility testing has no impact on the management of 24 patients and has led to the worsening of the management of two patients. The effect of antimicrobial susceptibility testing of antibiotic de-escalation was assessed in 35 patients; however, antibiotic de-escalation occurred in six patients. Thus, data of antimicrobial susceptibility testing has improved the management of Libyan outpatients with bacterial infection but their role in antibiotic de-escalation was slight

Tuberculosis (TB) is an infectious disease caused by bacteria called Mycobacterium tuberculosis. The disease mainly affects lungs and causes pulmonary tuberculosis. It can also affect intestine, meninges, skin, bones and other tissues of the body. Although the drugs alone can cure TB, it still remains a major public health problem worldwide. The aim of the study was to assess the quality of life and medication adherence in TB patients. The Quality of life was assessed using SF-36 in patients receiving DOTS treatment in initial or continuous phase while the medication adherence was analyzed using Morisky Green Levine Scale. Subjects were also counselled about their disease during their first visit and a follow up was done after a month. A total of 152 subjects were enrolled in the study of which majority of the subjects had Pulmonary TB (55.26%). Diabetes was found to be the most common comorbidity followed by HTN. The average Physical Component Summary (PCS) and Mental component summary (MCS) were found to be 44.34 and 39.60 respectively. Females had a better quality of life scores compared to males. High adherence was seen in 32.24% of patients while 28.29% had low adherence. Follow up was done for 135 subjects. 15 subjects defaulted and 2 of them died. There was a significant increase in the QoL scores and medication adherence after one month. A significant association was found between the Physical functioning (p=0.001) and emotional wellbeing (p=0.01) with Duration of treatment indicating that subjects who had completed more than one month of their treatment had marked improvement in Physical functioning and emotional well-being scores
Three species of arbuscular mycorrhizal fungi (Glomus fasiculatum, Glomus mossae and Acaulispora laevis) were used as bio-agents to manage black bundle disease of maize caused by C.acremonium. The results revealed that colonization of arbuscular mycorrhizal fungi in root system of the host reduce the percentage of disease incidenceconsiderably.In the pots inoculated with G. fasiculatum no disease incidence (0.0%) was recorded whereas, in the pots inoculated with A. leavis and G. mossae 16.66 % of disease incidence was recorded and the pots treated with pathogen shows 66.66% of disease incidence compare to control. Among the three bio-agents, Glomus fasiculatumproved to be more effective in managing the disease followed by G.mossae and A. laevis. In addition, all the three AM fungi enhanced the plant growth when they are used alone as inoculum as compared to dual inoculation with the C. acremonium and overall control. This clearly suggests that, AM fungi if used, can serve dual purpose. It can be used as bio-control agent as it shows negative antagonistic interaction soil borne plant pathogens and used as growth promoter because of the ability to supply macro and micro nutrients to the host plants.
Aging seldom comes alone and it is considered to be the major factor for many diseases and comorbidities and disabilities. The objectives of the study are to examine demographic characteristics and prevalence of comorbidities and polypharmacy of elderly patients who were admitted at Sebha Medical Center according to the selected period. This study is descriptive and retrospective cross-sectional study conducted in Sebha during 2021. From 195 participants of the study, the highest rate of patients was from the age group of 65 - 74 years which accounted for 86 participants (44%) and followed by those age group of 75 - 84 years which was reported by 65 participants (33%). The majority of elderly patients have hypertension, (n = 116, 59%) and over one-third of the patients (n = 73, 37%) have diabetes mellitus while nearly one-quarter of patients have both diseases at the same time (n = 47, 24%). Nearly, three-quarters of patients have electrolytes imbalance (n = 142, 72%). Nearly, two-thirds of the patients had three to five comorbidity diseases (n = 122, 63%). Whereas, over one-third of the patients had just one or two comorbidities (n = 70, 36%). Almost all the participants have polypharmacy (n = 187, 96%). Just above half of the patients have five - ten medications (n = 100, 51%) compared with 45% of the patients from those who have more than ten medications (n = 87). This study showed that there is a strong relationship between the prevalence of polypharmacy and the number of comorbidities. A Spearman correlation test indicated that rate of comorbidities was related to polypharmacy with a significant correlation (P < 0.01). The present study found high prevalence of comorbidities and polypharmacy among elderly inpatients. Based on this high prevalence, practicing pharmaceutical care could play an effective role to reduce the risk of inappropriate polypharmacy among hospitalized elderly patients through encouraging clinical pharmacist to engage in clinical activities in hospitals.

Although the importance of service quality has been recognised, few studies have addressed service quality in hotels from the perspective of employees. Therefore, this study aims to measure the service quality of four and five-star hotels in Jordan from the employees’ perspective based on the SERVQUAL model. The current study was carried out by measuring the data gathered according to a five-point Likert scale. A quantitative survey method was applied, and therefore the SERVQUAL instrument was used to measure service quality. Data obtained from a sample of 238 respondents drawn from ten four- and five-star hotels in Jordan were analysed with the SPSS software based on descriptive statistics. The study’s findings indicated that service quality of five-star hotels in Jordan was higher than that of four-star hotels.
This paper throws light on the role played by culture and traditions specifically of Hindu religion in legitimising the subordinate position of women in Indian society. Along with presenting a brief account on the status of women from ancient times to contemporary situation, the sex-gender binary has also been explored. How a child after his birth socialised to behave in a certain way on the basis of his/her sex has been noted. This process of socialisation is based on the age old customs and traditions which are discriminatory in nature. The male child is taught to be strong, dominating and aggressive in nature and henceforth assigned laborious work to do for managing the finances of house. On the other hand, female child is taught to be sensitive, loving and caring and therefore assigned to manage household work, child nurturing and motherhood related responsibilities.
The current study was conducted to explore the antiemetic activity of ten aromatic medicinal plants viz., Carissa carandus L. (fruits), Chichorium intybus L (flowers), Cinnamum tamala L (leaves), Curcuma caesia Roxb (rhizomes), Lallemantia royleana Benth (leaves), Matricaria chamomila L (flowers), Piper longum L (fruits), Piper methysticum G. Forst (fruits), Piper nigrum Linn. (fruits) and Syzygium aromaticum (Linn.) Merr. & Perry (flowering buds) was studied using a chick emetic model. The ethanol extracts of these plants were administered at 150 mg/kg body weight orally. Domperidone was given at 100 mg/kg as a reference drug. All the extracts decrease in retches induced by copper sulphate pentahydrate given orally at 50 mg/kg body weight and showed comparable antiemetic activity with domperidone. Compound targeted antiemetic activity is further suggested. Aromatic plants have tendency to relief from nausea. Alpinea offinarum,Zingiber officinale, Mentha piperita, Menthaspicata and Lavandula angustifola,are aromatic plants reported to possess antiemetic activity.

This paper compares different optimizable machine learning classification models to predict eight types of anemia from complete blood count (CBC) data. For the research, we used a publicly available Kaggle dataset containing 1281 observations, 14 predictors, and the diagnosis as the categorical target variable with nine categories (eight types of anemia and the healthy category). First, we examined the dataset and observed the histograms of some of the predictors. We compared the values of predictors of observations with no anemia to the observations where any anemia was diagnosed. Next, we used MATLAB R2024a to train and test nine optimizable machine-learning classification models. These models were Ensemble, Tree, SVM, Efficient Linear, Neural Network, Kernel, KNN, Naïve Bayes, and the Discriminant. Bayesian optimization was used to optimize the hyperparameters of all these models. We used 90% of observations for training and 10% of observations for testing. During the training, 10-fold cross-validation was used to prevent overfitting. The results showed the best accuracy was reached with the Ensemble classification model using the bag ensemble method (validation accuracy: 99.22%, test accuracy: 100%). Finally, we inspected our best classification model in more detail. We calculated the permutation feature importance to determine the contribution of each predictor to the final model. The results showed 6–7 important predictors, while the most important feature was the amount of hemoglobin.

Water contamination has become a global challenge which must be tackled. This study examined the contamination level of water in four locations at Ogbete area Enugu state. Carters street had the highest pH of 5.23 which is below the WHO standards limits for drinking water. The conductivities ranged from the highest conductivity 1445 μs/cm, which is below the WHO limits (8-10,000 μs/cm), TDS (1000 mg/l., TSS (WHO (500 mg/l). For alkalinity, the four locations were all below the (150 mg/l) standard set by World Health Organisation. Results showed that most of the physicochemical, biological and heavy metals parameters considered in this study were significantly above the permissible or allowed by WHO. It is therefore recommended that the water should be treated before use.
This study was aimed to develop lomustine loaded chitosan nanoparticles using a homogenization and spray drying technique. Effect of crosslinking agents (sodium tripolyphosphate (TPP), and sodium hexametaphosphate (HMP)) were studied on the leaching of drug, water uptake of hydrogels, drug release from matrix and its mechanism. Nanoparticles were obtained in the average size range of 111±16.2 to 942±11.7 nm with polydispersity index (PDI) from 0.116±0.039 to 0.517±0.037. Zeta potential of nanoparticles was ranged from 29.0±1.1 to 56.0±1.1 mV. The % encapsulation effi ciency of nanoparticles ranged between 58±0.88% and 96±0.51%.nanoparticles were coated with PEG 6000 to modulate drug release. Swelling index of chitosan-TPP and chitosan-TPP-PEG nanoparticles was about 428% and 350% over the 4 h and it was more (about 465% and 395%) for chitosan-HMP and chitosan-HMP-PEG nanoparticles. Drug release was sustained and diffusion controlled. Optimized formulation was tested for anticancer activity and drug retention study. Cytotoxicity on human lung cancer cell line L132 was studied by trypan blue dye exclusion test. Drug loaded nanoparticles killed L132 cells more effi ciently than the corresponding drug alone (p< 0.05). Due to the increased surface area lomustine loaded TPP and HMP crosslinked chitosan nanoparticles showed better anticancer activity.
The share of renewable energy share in India's energy mix of India has been increasing recently owing to the promotion and implementation of various government policies that promote the use of renewable sources of energy, depleting fossil fuel levels, increasing fuel prices, and stringent laws for emission reduction worldwide. The increase in the use of solar-evacuated-tube-collector-based domestic water heating is the result of this transition from conventional to nonconventional sources of energy. The recent urban agglomeration is challenging to install these solar water heaters in every household because the roof space is limited. Space reduction can be achieved by reducing the collector area by varying the diameter of the evacuated tubes. This study used a single tube and tank arrangement model with a fixed inclination to achieve a thermosyphon effect in a solar water heating system with three different diameter configurations of 48 mm, 54 mm, and 72 mm, with a tube measuring 1800 mm in length. Thermal assessment of the thermosyphon-based evacuated tube-solar water heater using the ANSYS CFD simulation software involves measuring the temperature at three different positions in the tank to study the thermosyphon initialization. This study signifies that the 72-mm-diameter evacuated tube is more capable of initializing the thermosyphon effect in the system. Nevertheless, the final temperature of the system is better achieved in the 48-mm-diameter evacuated tube
The National Assessment and Accreditation Council (NAAC) is an autonomous body established by the University Grants Commission (UGC) with headquarters in Bangalore to assess and accredit higher education institutions (HEIs) in India. Its objectives are to evaluate and accredit institutions of higher learning, enhance the quality of teaching, learning, and research, and offer financial support for workshops, conferences, and seminars. India is regarded as one of the biggest college and university systems in the entire globe, and fixing today's problems would require competent administration of these kinds of institutions. The purpose of the National Academic Accreditation Council (NAAC) is to ensure that higher education is of a high caliber. This was the driving force behind the NAAC's creation. Indian Higher Education Institutions (HEIs) are evaluated and accredited by the National Assessment and Accreditation Council (NAAC), an independent organization created by the University Grants Commission (UGC). The socioeconomic and cultural growth of any country is greatly influenced by higher education. With an increase in both the number of educational institutions and learners enrolled in various programs, higher education in India has grown significantly in recent years. This report presents policy recommendations for education systems to help all children succeed in their schooling, focusing on system and school-level policies to promote equity and quality. In order to support all students toward academic success, this study offers suggested solutions for education systems that center on system- and school-level policies that uphold quality and equity. Additionally, since expanding chances helps both the educational system and society at large, it offers proof on how to assist underprivileged kids and schools. It also provides evidence on how to support disadvantaged students and schools, as improving opportunities benefits the education system and societies as a whole.
The main objective of this study is to examine the relationship between globalization, resource conflicts and peace –building in Africa, with particular emphasis on Nigerian’s north-central geo-political zone. The wave of globalization that has swept across the world with its attendant socio-economic and political consequences lies at the heart of this study. The debate that is raging currently amongst intelligentsias, public analysts, and the international community point to the fact that the global system has suffered increasing setbacks occasioned by the impacts of globalization and contestation for scarce natural resource endowments. The changes that have emerged for several decades in both developed and developing nations, with the latter having a greater share of repercussions, have remained largely daunting. The multiplier effects of these changes have resulted in worsening crisis situations, with a fast growth rate of intra-state and/or trans-regionalized networked conflicts, which is why Africa and indeed Nigeria, has become a hotbed for contestations recently. This work adopts a qualitative approach as a method of investigation. This work relies on classic works of experts in the broader discipline of globalization and conflict resolutions, the essence of which is to clearly define ways of ensuring absolute peace in Nigeria’s north-central zone. The paper observes that guaranteeing peace-building requires the adoption of both vertical and horizontal approaches as templates for the realization of peace objectives.
