This study was conducted to develop and evaluate the Optimal Poly-1-Order (OP-1) model for approximating solar photovoltaic (PV) power generation. Using a mixed research method, the study employed Ibrahim’s simulation and prediction of grid-connected PV system theory with two objectives and their corresponding research questions. The study gathered primary and secondary data to approximate the implementation of a solar-PV system with an OP-1 model for generating electricity: optimizing energy production, load demands, and financial viability in the medical hostel facility of the University of Port Harcourt, Rivers State, Nigeria. With the use of simulation and descriptive methods of data analysis, results showed that the lighting system had 400 lights, each with 12W power. It operated for a total of 18 hours. Daily power consumption was 36,400 Wh. More so, it showed that 60 fans with 100W power were used during the same hours, resulting in a daily power usage of 108,000 Wh. Based on a comprehensive economic evaluation, the OP-1 solar-PV system was found to be economically viable for powering the medical hostel. The system met electricity demand, resulting in a remarkable 407% ROI and substantial savings for the grid, despite a lower optimized size of 193kW compared to the base peak generation of 383.90k. The study concluded and recommended that the proposed OP-1 Solar-PV power plant can meet the facility's electricity needs with a peak generation of 383.90kW and detailed energy analysis. Deploying this efficient solar-PV setup guarantees reliable and green electricity for the Medical Hostel, slashing the campus's carbon footprint and grid reliance.

Chronic kidney disease is a public health problem affecting people worldwide. This study was aimed to examine the characteristics of patients with chronic kidney disease and to identify prevalence of drug-related problems among Libyan patients. This is a descriptive retrospective study carried out in Southern-west part of Libya, Sebha City. Information abstraction forms were used for collection of data. The investigators reviewed the medications, medical records and laboratory data to identify drug-related problems.1 000 patients' files during 2019-2020 were examined and only 120 files were selected for this study. The majority of the participants were male (73, 61.0%) and the mean age was 56.1 years. 576 comorbidities among the selected patients were identified (73.61%) and the average number per patients was 4.8 concurrent diseases. There were 1 350 medications prescribed and the average of prescribed drugs per patient was 11.25. The majority of patients use more than 10 drugs (64, 53.3%) and the average length of staying in the hospital was 5.58 days. 502 drug-related problems were identified with an average of 4.18 per patient. Untreated conditions such as Hyponatremia and anemia were the highest rate of drug-related problems identified (199, 39.6%) followed by improper drug selection (82, 16.3%) such as cefotaxime, vancomycin and aminoglycoside for chronic kidney disease and drug use without indications such as antibiotics (68, 13.5%) and over-therapeutic dose such as metoclopramide(63, 12.5%). In conclusion, all the patients have polypharmacy and the majority have comorbid conditions and chronic kidney disease with frequent drug-related problems, thus, to lower the incidence rate of drug-related problems, therapeutic interventions are needed. Subsequently, it is a crucial to involve clinical pharmacist in hospital to improve the care of patient with chronic kidney disease.

Background: Exhaust noise is known to be a major pollutant in the environment and workplaces due to the development of industry and transportation. Exhaust noise can be reduced to normal levels by mufflers or silencers. A reactive muffler efficiently dampens noise at low frequencies by reflecting sound waves. Therefore, muffler design is of great importance in exhaust noise reduction. Transmission loss (TL) is an essential characteristic of mufflers, demonstrating their acoustical properties. Any acoustical appliance is selected based on its damping performance and reliability. Predicting TL through experimentation is different from theoretical calculations. Methods: In the present study, a double-expansion chamber muffler was designed as a reflective muffler on a laboratory scale by equations. Next, TL was evaluated by an impedance tube applying a 4-microphone technique to determine the acoustical performance of the designed muffler. Results: Findings revealed that the TL of the muffler at 312 Hz frequency obtained 27.5 dB agreement with the required TL of the muffler of 25 dB. In addition, the TL of the muffler against frequency attenuates noise in broadband frequencies. Conclusions: These results indicated that the built muffler provides desired TL for exhaust chambers. Therefore, equations can be used as a precise method for muffler design. Furthermore, multi-expansion chamber mufflers are useful for reducing noise at a wide range of frequencies.
Background: The significance of healthcare wastes (HCWs) consists in their hazardous component, which constitutes real danger to public health. In Nigeria, healthcare waste management (HCWM) has remained a problem yet to be properly recognized and so addressed. The study aimed to sensitise health workers and the public on the need for proper management of HCWs, considering the public health implications of not doing so. Methods: The waste management systems of ten healthcare facilities (HCFs) were assessed, using a modification of the WHO rapid assessment tool. In each HCF, segregated wastes were collected daily for ten days and quantified by weighing, using a spring balance. Results: Administratively, the HCWM system was poor in the ten HCFs (40.6%). 70% of them had satisfactory waste segregation, 81%, good waste treatment, and 26.7% adequate transportation methods for waste. None of the HCFs had budget allocation for HCWM, and 90% had inadequate storage facilities. Mean waste generation was 1.81 kg/day, 0.23 kg/patient/day, 0.16 kg/bed/day, and proportion of infectious wastes 16.8%. Correlation between the number of patients and proportion of infectious waste, was positive, strong and significant (r=0.80, p=0.01), and between bed occupancy rate and proportion of infectious waste, was positive too, but weak, and insignificant (r=0.34, p=0.34). Conclusions: In view of the identified weaknesses of the ten HCFs in HCWM, budget allocations for HCWM, improving waste storage facilities and transportation, with strengthening of waste segregation, collection, and treatment, would help to ensure adequate HCWM in the HCFs.
Background Covid-19 pandemic has hit many countries and put the majority of the public health system to test globally. Mandatory use of face mask was among policies set by the government to contain the spread of the novel disease. But citizens’ attitudes and compliance with these policies are important in controlling the pandemic. We assessed gender-based compliance to Covid-19 protocol (use of face mask) in Jos South, Plateau State, Nigeria. Methods Perception regarding Covid-19 and the use of face masks were assessed among participants using a questionnaire-based survey. In a cross-sectional study, ninety (n=90) questionnaires were administered to willing participants directly. A Chi-square test was used to determine the descriptive analysis of all responses, P-values <0.05 were considered statistically significant. Result Out of 90 participants, 55.6% (50/90) were male and 44.4%(40/90) were female. Forty-two (84%) males deny the existence of the pandemic while in females, 14 (35%) deny that Covid-19 exist. Thirty-seven (74%) of the male respondents do not comply with to use of the face mask and use a single face mask multiple times without decontamination. In females, 28 (70%) comply with the use of the face mask. Unlike the men, 20 (50%) of the females always decontaminate the face mask. The middle-aged adult (26-45 years) uses the face mask more than the young (18-25 years). There was a significant association of gender in relation to the perception of Covid-19 and the use of facemask (p< 0.05). Conclusion Male respondents showed an irresponsible attitude complying to Covid-19 protocol than the females, therefore, enlisting them as a risk factor for the continued spread of the virus. We recommend that public health awareness and campaigns should focus and employ greater influence on men and young adults in their compliance with the preventive protocols.
Online interviews can be powerful tools in global health research. In this article, we review the literature on the use of and challenges associated with online interviews in health research in Africa and make recommendations for future online qualitative studies. The scoping review methodology was used. We searched on Medline and Embase in March 2022 for qualitative articles that used internet-based interviews as a data collection method. Following full-text reviews, we included nine articles. We found that online interviews were typically conducted via Microsoft Teams, Zoom, Skype, WhatsApp, Facebook Messaging and E-mail chats. Online interviews were used in Africa because of the restrictions imposed by the coronavirus disease 2019 pandemic and the need to sample participants across multiple countries or communities. Recruitment for online interviews occurred online, interviews were characterised by inaudible sounds, the inability to use video options and the challenges of including people with low income and education. We recommend that researchers critically evaluate the feasibility of online interviews within a particular African locality before fully implementing this data collection approach. Researchers may also collaborate with community-based organisations to help recruit a more socioeconomically diverse sample because of the potential of excluding participants with limited internet access.
In addition to predatory journals and publishers, researchers now need to be wary of predatory conferences as well with the checklist given here to really check yourself.Because the predatory journals and publishers make target to the new researchers there must be need of that type of articles
Chest wall schwannoma is a rare intercostal nerve tumor originating from Schwann cells. Here, we present a case of a 44-year old woman who presented with symptoms of cough, fever, and left-sided chest pain. A plain chest radiograph was unremarkable and was further evaluated with a contrast-enhanced chest computed tomography (CECT) scan, which showed a well-defined, encapsulated soft-tissue mass in the left anterior first intercostal space. The diagnosis of schwannoma was based on histopathological and immunohistochemical studies of tissue biopsies taken from the lesion. The patient was referred to a higher oncology center for further treatment where he received symptomatic treatment for the pain and cough after which he improved. The patient was discharged and followed up in the clinic. Six months later, the patient underwent another chest CECT, which revealed no growth in size from the first one. Therefore, it was decided to keep the patient in regular follow-up since the lesion remained stable in size.
Cystic fibrosis is a challenging disease which creates many complications. The impact caused from cystic fibrosis on an adolescent is a challenging phase for their lives. Negative impacts like the society’s pressure, anxiety and depression are few common reasons that are being unspoken and ignored due to complexity of the disease. This study is aimed to identify the necessary gaps and educate the necessary policy makers and CF center health care team to have a better understanding about the context of the aftermath of cystic fibrosis and enhance better patient care. More over this systematic review also points out the main trends in this field of study. Qualitative study and quantitative are prominently used research methods to gain an understanding the about the gaps in the research. However, there is still a scarcity of quantitative and mixed research methods. Furthermore, limitations such as language, cultural influences were identified whilst going through the analysis. Overall through the information given in the following in this study more information regarding that warrants answers can be identified which will lead to proper care towards the teenagers who suffers from cystic fibrosis
Family businesses must harness the full potential of their human resources and maintain employee loyalty to achieve the companies’ objectives effectively. This study examines the influence of transformational leadership on employee commitment through work-life balance and workplace social support. The research was conducted from August to December 2023 using an online questionnaire distributed to employees in a family firm in Medan, Indonesia. The data were then analyzed using PLS-SEM. The results show that transformational leadership significantly effects employee commitment, work-life balance, and workplace social support. However, although workplace social support mediates the relationship between transformational leadership and employee commitment, work-life balance fails to do so. It was also found that work-life balance has no direct influence on employee commitment. Using an IPMA analysis, this study highlights the importance of transformational leadership and workplace social support in the family business environment. Transformational leadership has also been shown to have the best performance and effect on employee commitment. Managers should prioritize these aspects to reduce employees’ stress levels, improve psychological well-being, and increase job satisfaction, leading to a more committed, high-performance workforce.
The seed flours of Macrotyloma uniflorum (Lam.) Verdc., Phaseolus lunatus Linn., and Phaseolus vulgaris Linn. were investigated for their total, soluble and insoluble oxalate contents by HPLC. The total oxalate content of Macrotyloma uniflorum, Phaseolus lunatus and Phaseolus vulgaris were 1.24, 1.77 and 1.71 mg/ g, respectively. The % age of soluble oxalate was Macrotyloma uniflorum (19.50), Phaseolus lunatus (15.08) and Phaseolus vulgaris (15.88). The calculated soluble oxalate: calcium ratio of all tested legume flours is lesser than one and hence will not create any resistance in calcium bioavailability.
In childhood, epilepsy is the most common globally widespread neurological problem, usually with serious consequences for this most critical period of development. Dravet and Lennox Gastaut syndromes are two forms of rare and severe treatment resistant epilepsies that occur early in the life. These resistant epilepsies recognised by continuous unrelenting seizures of many types including the occurrence of status epilepticus. In addition, it is associated with the development of behavioural, neurological, cognitive deficits and the sequelae of increased risk of mortality rate. Historically, cannabis was found to possess several medical benefits including its use for epilepsy. In this review, information and data were extracted from 99 references using PubMed and Google Scholar (November, 2021). Data with clinical evidence on cannabidiol regarding its efficacy on Dravet syndrome and Lennox Gastaut syndrome, mechanism of action, safety, pharmacokinetic properties and interactions with anti-epileptic medications were all reviewed and discussed. Highly purified cannabidiol is a cannabis derived compound that is suggested in recent research as an add-on therapy to the existing treatment of both resistant epileptic types; since it is able to reduce the duration, frequency and severity of seizure disorders. It is also characterised with multiple signalling transduction mechanisms, primarily via inhibition of excitatory and potentiation of inhibitory pathways.

Use of chemical fungicide to control plant diseases causes several adverse effects such as, development of resistance in the pathogen, residual toxicity, pollution to the environment etc. So an alternative way to overcome the usage of dreadful chemicals is very important. The use of plant extracts as biofungicide is one of the popular and effective method. Araucaria columnaris is a commonly seen ornamental plant known as Christmas tree. It’s a South African species, under the family Araucariaceae. Hence, in the present study, the plant resin extract was tested in-vitro against major plant pathogensby preliminary bioassay. It was found that up to 95% reduction of mycelium growth was observed against major phytopathogens such as Fusarium oxysporyum, Rhizoctoniasp, Cylindrocladiumsp, Alternariasp, and Colletrotricum sp., causing tomato wilt, damping off, foliage blight, and leaf blight diseases in economically important plants. Up to our knowledge it is the first report showing the antifungal activity of Araucaria columnaris resin as antifungal agent. By using this valuable tree, further work will be done to formulate commercial biofungicide.
India is not known as a country to be in for a bisexual person. Homosexual acts even within wedlock are a punishable offence in India. Legal battles over provisions in the Indian Penal Code which criminalizes any sexual act “against the order of nature” are rife. Even though Kerala has been hailed as a paradox inside India (mainly due to its human development parameters), the social, cultural and legal environment in the state is hostile to individuals who question hetero-normativity. Non-judgemental and unbiased scientific therapy or counselling are seldom available to sexual minorities. This paper is an attempt to map the experiences of a female who is openly bisexual, and is living in Kerala. An ethnographic interview was conducted where the experiences of the participant are explored, from the relationship dynamics as seen by her, to sexual experiences and difficulties in relationships. A reference is also made to the personal and social support systems that are in place for the Lesbian, Gay, Bisexual, Transgender (LGBT) community in Kerala and their role in initiating discourses regarding the topic. A few pointers for future studies in the topic, especially within the context of Kerala are also put forward.
A mobile adhoc network is a Self-configuring network of mobile routers connected by wireless links. In the mobile adhoc network, each and every device moves independently in any direction so that there are frequent changes in the links. It is essential to learn the position of the neighbors because there is increase in location-aware services. So, there is a chance that the malicious nodes are easily abused the process. The significant problem in mobile networks is correctness of node locations and also it is primarily challenging in the presence of adversaries. So, the neighbor position verification protocol is used to a fully distributed, a lightweight NPV procedure which allows each node to obtain the locations advertised by its neighbors and asses their truthfulness. Further to extend neighbor position verification protocols in the proactive model that need to each node constantly verify the position of its neighbors. So, we introduce a technique called secure link state updating which provides secure proactive topology discovery that is multiply useful for the network operation. This technique is vigorous against individual attackers, it is capable to adjust its capacity between local and network-wide topology discovery, and also operating in networks of frequently changing topology and membership nodes. Experimental results show that the proposed system is high efficiency in terms of security when compared to the existing system.
Education is power. It constitutes the foundation of all the multidimensional socio-economic development of a country. In the present context, we need manpower or human capital for generating the growth and development in a country. The Government of India has taken several many initiatives for promoting education at all the stages i.e. Primary, Secondary and Higher. But still, we find such issues as a high dropout rate at all the stages of education, rural-urban disparity, gender disparity, interstate variations pose as some of the problems that impedes the development of human resources in our country. Even the work participation rate in India indicates the necessity of proper planning of skill training and employment opportunity. Most interestingly, the existing general and conventional higher educational institutions have not effectively been able to cope with the contemporary challenges and changes with the result that the nature of curriculum which is by and large in place tends to create only degree inflation in our country. So, we need such institutes and institutional arrangement that can cater to the contemporary challenges so as to upgrade the quality of education as well as to provide need based educational programmes that can develop human power in the society. Effective or quality education especially at higher level can play a vital role in bringing around multifaceted human resource development, enabling the learner’s absorption in the job market and selfemployment. This paper will discuss how the accessibility of education can be promoted to all through a convenient mode of education system and how the disparities in education can be minimized, and also focus on the various strategies for strengthening higher education system in the country.
Oxalate is widely distributed in plant foods as potassium, sodium and ammonium oxalates (water-soluble form) and as insoluble calcium oxalates. Oxalate forms strong chelates with dietary calcium, thus rendering the complex unavailable for absorption and assimilation. It precipitates as insoluble salts accumulating in the renal glomeruli and contributes to the development of renal disorders. The seed flours of Macrotyloma uniflorum (Lam.) Verdc., Phaseolus lunatus Linn., and Phaseolus vulgaris Linn. were investigated for their total, soluble and insoluble oxalate contents by HPLC. The total oxalate content of M. uniflorum, P. lunatus and P. vulgaris was 1.24, 1.77 and 1.71 mg/ g, respectively. The %age of soluble oxalate were M. uniflorum (19.50), P. lunatus (15.08) and P. vulgaris (15.88). Only soluble oxalate is responsible for oxalate absorption (bioavailability) and its excretion. Overall, the total oxalate content is high in legume flour of M. uniflorum, P. lunatus, and P. vulgaris, but the soluble oxalates are very low. Therefore, all these three legumes don't have the adverse effects of oxalate on minerals bioavailability and risk of urolithiasis.
This study was carried out to evaluate the effects of thermal processing techniques on the nutrient and antinutrient contents of pigeon pea (Cajanus cajan) flours. The pigeon pea seeds were sorted, cleaned and divided into five equal lots of 0.5kg each. Four lots of pigeon pea seeds were processed into blanched, boiled, roasted, and autoclaved pigeon pea flours, while the fifth lot was processed raw and used as control. The raw and thermally processed samples obtained were analysed for nutrient and antinutrient composition using standard methods. The proximate composition of the samples showed that the flours had a range of 8.61 - 11.46 % moisture, 21.13 - 23.94 % crude protein, 1.26 - 1.68 % fat, 5.12 – 6.10 % crude fibre, 1.74 – 2.97 % ash, 55.56 – 60.41 % carbohydrate and 333.45 - 342.75 kJ/100g energy, respectively. The mineral composition showed that the flours contained 86.24 – 144.72 mg/100g calcium, 137.80 – 170.33 mg/100g magnesium, 125.86 - 156.76 mg/100g potassium, 66.66 – 95.62 mg/100g sodium, 4.38 – 6.64 mg/100g iron and 130.27 – 178.29 mg/100g phosphorus, respectively. The vitamin content of the flours were 3.09 - 4.33 mg/100g ascorbic acid, 0.05 - 0.17 mg/100g thiamine, 0.03 - 0.21 mg/100g riboflavin, 0.13 - 0.28 mg/100g niacin, 3.21 - 6.25 mg/100g vitamin A and 1.10 - 2.70 mg/100g vitamin E, respectively. The antinutrient composition of the flours also showed that the levels of trypsin inhibitor, tannin, phytate, oxalate, saponin and haemagglutinin ranged from, 2.30 – 5.61 Tiu/mg, 0.81 – 1.5mg/100g, 1.12 - 4.18mg/100g, 0.48-4.01 mg/100g, 1.28 – 3.66 mg/100g and 1.30 – 7.44 Hiu/g, respectively. Therefore, the study showed that thermally processed pigeon pea flours could be used as nutrient dense ingredients in the preparation of a wide range of foods for children, adolescents and aged adults especially in developing countries where the problems of protein-energy malnutrition and micronutrients deficiencies are prevalent than the raw sample.
The development of smart phone technology has lead to denigrate of the phone prepared with many sophisticated features such as sensors. Camera is one of the most extensively used sensors. Although the photographs capture by camera can be shared via Multimedia Message Service (MMS) which allows broadcast of files like photographs, audio and video. A major problem of MMS is, it doesn’t provide adequate safety mechanism. Because of this, the data of the people who wants to conceal confidential information from state-controlled systems that can be easily monitored. Video Steganography is a technique to hide any type of files in any extension into a Video file. The idea proposed in this paper is to embed any kind of data in another file, which is called carrier file. The carrier file must be image video file. Steganography is the art of hiding messages inside other messages such that the very existence of the message is unknown to third party. In this paper, a steganography-based android mobile application that can insert the confidential information into an image, then into a video that can be send it to receiver. Finally we can extract the confidential information from the image in the receiver side.
