Published: February 2024

In order to operate photovoltaic (PV) systems using maximum power point tracking (MPPT), three distinct combinations of controllers and converters are proposed in this research and compared. Using MATLAB/Simulink simulation, these strategies are assessed based on the output parameters of time, power, and current. The demand on power production has increased manifold in recent years and on the other hand, the conventional resources utilized for it will be vanished in near future. The requirement of PV based generation is getting increased. The procedure of getting solar energy from a solar panel is common. With MPPT, here the output obtained must be the same quantity of energy even when the source of that energy is partially available. Climate change and other issues could be to blame for this inefficiency. In this project three distinct converters and three distinct controllers have been compared. All three converters are linked to each controller individually, and measurements of current, voltage, and power are analysed. By which the result is obtained. After the comparison of nine outputs, the most powerful and efficient combination is identified. By doing this, the converters and controllers produce high D.C voltage. Direct voltage transmission to the MMI. A.C. voltage is created by converting D.C. voltage. Increase the MMI's output by doing this. The voltage generated by the MMI is sent to the grid for domestic usage. Even when the source is not readily available, the solar panel's voltage can still be used.

BACKGROUND
Portal vein thrombosis (PVT) is a commonthsn complication after splenectomy in patients with cirrhosis. However, the predictors of postoperative PVT are not known.
AIM
To investigate the predictors of PVT after splenectomy in patient with cirrhosis.
METHODS
A total of 45 patients with cirrhosis who underwent splenectomy were consecutively enrolled from January 2017 to December 2018. The incidence of PVT at 1 months, 3 months, and 12 months after splenectomy in patients with cirrhosis was observed. The hematological indicators, biochemical and coagulation parameters, and imaging features were recorded at baseline and at each observation point. The univariable, multivariable, receiver operating characteristic curve and time-dependent curve analyses were performed.
RESULTS
The cumulative incidence of PVT was 40.0%, 46.6%, and 48.9% at 1 months, 3 months, and 12 months after splenectomy. Multivariable analysis showed that portal vein diameter (PVD) ≥ 14.5 mm and monthsdel‎ end-stage liver disease (MELD) score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy (P < 0.05). Time-dependent curve showed that the cumulative incidence of PVT was significantly different between patients with MELD score ≤ 10 and > 10 (P < 0.05). In addition, the cumulative incidence of PVT in the PVD ≥ 14.5 mm group was significantly higher than that in the PVD < 14.5 mm group (P < 0.05).
CONCLUSION
Wider PVD and MELD score > 10 were independent predictors of PVT at 1 months, 3 months, and 12 months after splenectomy in patient with cirrhosis.

Wrong identification and characterization of Theileria species in cattle may be associated with economic loss via low productive rate in cattle business. A study was designed to compare microscopy and polymerase chain reaction (PCR) in identification and characterization of Theileria species of cattle within Makurdi, Benue State Nigeria. Blood samples were collected from cattle of both sexes and analysed microscopically using thin blood film and DNAexamination was done using polymerase chain reaction (PCR). Theileria species were identified and characterized by PCR amplification using species specific primers of 18s rRNAfor TheileriaSpp. Data obtained were analysed using chi square, and P values at less than 0.05 were considered significant different. The result revealed the presence of Theileria. The result of comparison of prevalence of infection of Theileriosis using microscopy and PCR revealed that, microscopy was able to detect only 1.77 % of Theileria but PCR detected 13.3% of Theileria. The percentage of prevalence of Theileria species was highly detected by PCR than microscopy and this was statistically significant (P < 0.05). Theileriosis in cattle have been seen to be prevalence in Makurdi metropolis and molecular method such as PCR can effectively.

Camel Trypanosomosis (Surra), caused by Trypanosoma evansiis a serious problem in the camel-rearing regions of Nigeria. In the present study, 150 camels slaughtered in Sokoto central abattoir were examined for the presence of antibodies and DNA of T. evansi using the Card Agglutination Test (CAT) and Polymerase Chain Reaction (PCR) methods, respectively. Antibody and the DNA of T. evansi were detected in 42 (28.0%) and 68 (45.3%) of the animals tested by the CAT and PCR, respectively. Higher prevalence was found among young camels compared to the adults using CAT (33.3% vs 27.8%), while adults had higher prevalence than the young (46.5% vs 16.7%) using PCR technique. Both the techniques recorded higher prevalence in males than females; CAT (28.3% vs 25.0%) and PCR (49.3% vs 0.0%). The detection of T. evansi DNA was significantly associated with the age (p=0.001) and sex (p=0.002) of camels, but not for the serological technique (p> 0.05). The detection of antibodies and DNA of T. evansi in camels in this study attest to the possibility of continuous exposure of camels to infections. The role of Surra in camel production in Nigeria and the need for holistic control measures are discussed.

Published: February 2024

Vegetables are crucial for a healthy diet; however, when not washed properly, they can act as carriers of protozoa cysts and helminth eggs/larvae, posing a risk of transmission. The study aimed to determine the prevalence of parasitic contamination of fluted pumpkin promoted by inadequate handling conditions in Delta State, Nigeria. Samples of Telfairia occidentalis (fluted pumpkin vegetables) were collected from Effurun town and Otokutu local markets in washed and unwashed conditions and examined for parasitic contamination. An interviewer-administered questionnaire was used to obtain information on the socio-economic factors associated with parasitic contaminations on vegetables. The vegetable samples were examined using the simple sedimentation concentration method. The educational status of the vendors was ascertained, and 75% of the vendors had secondary school education, while 25% had primary school education. Four hundred seventyeight parasitic contaminants were recovered from the 48 vegetables samples. The species and stages of parasites detected were Trichuris spp, Moniezia spp, Enterobius vermicularis, Ascaris lumbricoides, Strongyloides spp, Hookworm eggs, Strongyle eggs Strongyloides stercoralis larvae, Schistostoma spp, Platynosomum fastosum and Eimeria spp. Fifty per cent (50%) of the produce was not washed, while 50% of the produce was washed before displaying by the retailers. The result from the paired t-test revealed a significant difference (p<0.05) in total parasitic contamination between washed and unwashed vegetable samples from both Effurun and Otokutu markets. This study showed that handling conditions of washing and the environment where vegetables are sold can influence the amount of parasitic load. Therefore, adequate washing and proper handling of raw edible vegetables before consumption are recommended. The government must create awareness and educate vegetable vendors about the importance of proper handling and hygiene, as they can play a major role in mitigating public health issues.

Parasites constitute a major problem for fish health and their prevalence hamper fish growth and productivity by increasing their morbidity and mortality. Fish endoparasites are often associated with zoonotic disease in humans. The aim of this study was to determine the endoparasitic prevalence and feeding habits of Oreochromis aureus, Amia calva and Clarias gariepinus, in Ase River, Delta State, Nigeria. Atotal of 104 fish comprising of 40 O. aureus, 21 A. calva and 43 C. gariepinus were collected from seven locations of the river during dry and wet seasons, for parasitological investigations. The livers, gills, muscles, small and large intestines of fish specimens were examined, and the sex determination was done by physical observation of the genital papilla, which appeared long in males and reddish round in females. From the specimens, 96 (92.3%) had 191 overall endoparasitic loads. The highest and lowest percentage abundance of 51.18% and 13.08% were recorded in Locations 1 and 4 had respectively. Of the 96 infected fish, 29 (29.8%) were male and 68 (70.1%) female, indicating a much higher infection rate in females. On prevalence abundance across species, A. calva was highest with 21(100%). C. gariepinus was 40 (93.0%) and O. aureus was least with 35(87.5%). The study also identified a total of 21 endoparasites in five taxonomic groups; Protozoans (32.46%), Nematode (38.74%), Annelid (3.66%), Trematode (15.70%) and Cestode (9.42%). The mean intensity of parasitic load showed 58.6, 37.0 and 31.6 to be moderately, highly and slightly affected. ANOVA result on prevalence indicated a significant distribution of endoparasites across specimens (P<0.05; P=0.001). Considering the effect of parasites on fish morbidity and mortality, human food-borne zoonoses, there is need for the communities and industries on the riverbank to adopt right policies for water pollution control.

Published: February 2024

This article explores the important role of hope in the Christian life by exploring the concept of hope in the Bible and the development of the theology of hope from the Old Testament to the New Testament. This research highlights that Christian hope is not just optimism based on current conditions, but a belief in divine promises that create new forces from outside the current situation. Theological analysis emphasizes the role of perseverance in nurturing hope amidst challenges and suffering. The article also discusses the paradox between divine involvement and God's hiddenness, emphasizing that Christian hope cannot always be predicted from the current situation, but rather stems from the promise of a certain future existence for humans. The results of this research say that hope is not just an emotional aspect or optimism, but a certainty that grows from belief in God who is involved in every aspect of life. Through this paradox, hope becomes a driver of courage and strength, creating a firm anchor that guides the steps of His people on the journey of life. Artikel ini mendalam tentang peran penting harapan dalam kehidupan Kristen dengan mengeksplorasi konsep harapan dalam Alkitab dan perkembangan teologi pengharapan dari Perjanjian Lama hingga Perjanjian Baru. Penelitian ini menyoroti bahwa harapan Kristen tidak hanya sekadar optimisme berdasarkan kondisi saat ini, tetapi sebuah keyakinan pada janji-janji ilahi yang menciptakan kekuatan baru dari luar situasi kini. Analisis teologis menekankan peran ketekunan dalam merawat harapan di tengah tantangan dan penderitaan. Artikel juga membahas paradoks antara keterlibatan ilahi dan ketersembunyian Tuhan, menegaskan bahwa harapan Kristen tidak selalu dapat diprediksi dari situasi saat ini, melainkan bersumber dari janji keberadaan masa depan yang pasti bagi manusia. Hasil penelitian ini mengatakan bahwa harapan bukan hanya aspek emosional atau optimisme, tetapi kepastian yang tumbuh dari keyakinan akan Tuhan yang terlibat dalam setiap aspek kehidupan. Melalui paradoks ini, harapan menjadi pendorong keberanian dan kekuatan, menciptakan suatu jangkar kokoh yang memandu langkah umat-Nya dalam perjalanan kehidupan.

Purpose: The aim of the study was to assess the transient hyperthyroidism of hyperemesis gravidarum: A case report from rural Kenya.
Materials and Methods: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: Hyperthyroidism complicates 0.2-0.4% of pregnancies. It may be diagnosed in the setting of hyperemesis gravidarum and can be pathological or transient. Untreated pathological hyperthyroidism has adverse maternal and fetal outcomes. Transient hyperthyroidism of hyperemesis gravidarum (THHG) affects up to 60% of women with hyperemesis, is self-limiting, and needs no antithyroid drug treatment. A diagnosis of THHG (rather than overt pathological hyperthyroidism) should be made when hyperthyroidism occurs in the setting of hyperemesis gravidarum and in the absence of pre-pregnancy hyperthyroidism, clinical findings compatible with maternal hyperthyroidism, and a negative antithyroid autoimmune profile. THHG resolves by the end of the first trimester without adverse pregnancy outcomes. We present a case from a rural Kenyan hospital to highlight the clinical profile and management of THHG for the primary care physician.
Implications to Theory, Practice and Policy: Assessment of thyroid functions is indicated in hyperemesis gravidarum, where there are clinical features of hyperthyroidism. THHG is a self-limiting benign condition that may inappropriately lead to unnecessary drug treatment for pathological hyperthyroidism in pregnancy. A diagnosis of THHG should be made when a laboratory picture of hyperthyroidism occurs in the setting of hyperemesis gravidarum in the absence of pre-pregnancy hyperthyroidism, compatible physical findings, and a negative antithyroid autoantibody profile.

O presente estudo se concentra na análise de pacientes com Infarto Agudo do Miocárdio com elevação do segmento ST (IAMCST) em diferentes faixas etárias, com o objetivo de comparar as características do tratamento intra-hospitalar e os desfechos clínicos. Com base em dados do Ministério da Saúde do Brasil, o IAMCST é a principal causa de mortes isoladas no país, ressaltando a significativa carga de mortalidade em populações idosas, especialmente aquelas acima de 65 anos. Este estudo explora a marcante heterogeneidade nos desfechos dentro dos grupos etários. Foi adotada uma abordagem observacional, utilizando o Registro Cardiovascular de Brasília para Qualidade dos Cuidados e Resultados (B-Care: QCO), envolvendo pacientes consecutivos admitidos em hospitais públicos em Brasília-DF com Síndrome Coronariana Aguda (SCA). Análises descritivas e testes estatísticos, incluindo qui- quadrado, ANOVA e Kruskal-Wallis, foram aplicados para avaliar as relações entre idade, tratamento e desfechos clínicos. Os resultados destacam uma correlação substancial entre idade avançada e maior mortalidade intra-hospitalar e taxas de insuficiência cardíaca pós IAM. Embora o estudo não tenha identificado uma correlação significativa entre os tempos de tratamento e os desfechos, investigações adicionais são essenciais para elucidar janelas de tratamento ideais, considerando variáveis multifacetadas.
