Wheat is the second largest contributor to Nigeria's food import bill and puts pressure on the foreign reserve of the nation. Land suitability assessment is a prerequisite to achieving optimum utilization of the available land resources. Lack of knowledge on best combination of factors that suit production of wheat has contributed to the low produce. The study aims to assess land suitability of wheat production in kano using selected physical materials with the objectives to map out existing locations for wheat production in kano state, determine other areas that may be suitable for wheat production. The study utilized Landsat 8; Shuttle Radar Topography Mission (SRTM) Multi-criteria Evaluator (MCE) integrated with GIS. Spatial factors for wheat cultivation such as soil texture, soil type, soil slope, rainfall range, geology map, elevation, land use land cover and their attribute were identified and were processed into spatial data. The factors were weighed according to their relevance. Land suitability model was constructed in ArcGIS software and spatial data were imported into (SRTM) and link to the land suitability model constructed. The spatial data integrated were computed and final visualization of land suitability map was produced and using ArcGIS 10.3 to identify potential areas. The result obtained showed that 16% were unsuitable, 19% were moderately suitable, 25% were highly suitably and then 40% were most suitable in the study area. Based on this finding, it is recommended that wheat cultivation should be practiced in a large scale in Kano state.

It is reported that variations in the nucleotide sequence of protamine genes play contributory role in men’s fertility. The aim of this study was to evaluate single nucleotide polymorphisms (SNPs) in protamine 2 genes (PRM2) of infertile and fertile men in Southwest, Nigeria. In this cross-sectional study, 92 volunteers (57 infertile men and 35 fertile men) age 30-59 years who visited fertility clinics at the time of this study were recruited after thorough evaluation of their clinical fertility histories and confirmation of their fertility statuses, aided by Computer Assisted Semen Analyzer and WHO guidelines for semen analysis. Polymerase chain reaction analysis of SNPs in PRM2 in the semen samples was determined. BLAST results of the 5’-UTR of PRM2, identified 16 novel SNPs in total, in the infertile and fertile men. Out of the 16 SNPs discovered, 15 SNPs were found in the infertile men, randomly distributed and 7 SNPs were discovered in the fertile men. However, there were six SNPs which were common between the infertile and fertile men. The common SNPs occurred at one or more loci in the PRM2 in the infertile men than in the fertile men. We found one variant rs2069880799 (16C>T) present in the fertile men but missing in the infertile men. In general, the SNPs in PRM2 were statistically different between the infertile and fertile men when compared. All the SNPs discovered, according to NCBI database were clinically non pathological.

ChatGPT, developed by OpenAI, represents a significant advancement in AI technology, particularly noted for its ability to engage in human-like conversations. This review article is about role of ChatGPT in antenatal care during pregnancy and its limitations in addressing health-related issues. While ChatGPT offers accessible and empathetic responses to queries about pregnancy and childbirth, its reliability and accuracy remain concerns. The model's reliance on statistical patterns in data often leads to biased or incomplete information, lacking necessary citations. Despite these limitations, ChatGPT shows promise in supporting clinical decision-making but requires oversight to ensure medical advice is precise and appropriate. Ethical considerations, including privacy and misuse risks, underscore the need for further development and validation in healthcare applications.

Introduction: Psoriasis is an uncommon condition in Africa. In sub-Saharan Africa, prevalence varies depending on the country and studies. Objective: The aim of this study was to determine the prevalence and search for factors associated with the most frequent clinical presentation of psoriasis in our context. Methodology: It was of a retrospective analytical cross-sectional study, over a period of 10 years. We included the files of patients diagnosed with psoriasis. The clinical form of psoriasis, age and comorbidities were collected. The analyzes were carried out using SPSS 22.0 software. A p value <0.05 was considered statistically significant. Results: In total, out of 16,943 consultation files, 106 cases of psoriasis were included, i.e. a prevalence of 0.7%. The average age in our population was 38.1 ± 21.4 years with a male predominance, a sex ratio of 1.8. The most common clinical form was psoriasis vulgaris (69.9%). The most common comorbidities were hypertension (4.7%), followed by metabolic syndrome (3.7%), and HIV infection (3.7%). After multivariate analysis, being a pupil or student increased the risk of developing psoriasis vulgaris (7.2[1.1-6]; p<0.046). Conclusion: Psoriasis vulgaris is the most frequent clinical form in the city of Yaoundé, being a pupil or student is a factor associated with common psoriasis.

Natural Rubber is one of the world's largest commodities used for industrial needs. The price of TSR 20 rubber continues to fluctuate, which has a significant impact on some farmers in various countries. This study analyzes the price trend of TSR 20 rubber in Southeast Asia. The purpose of this study is to analyze trends and fluctuations in STR 20 rubber prices in Southeast Asia, such as Standar Thailand Rubber (STR 20), Standar Indonesia Rubber (SIR 20), Standar Vietnam Rubber (SVR 20), and Standar Malaysia Rubber (SMR 20) for 72 months from January 2017 - December 2022. This research uses trend analysis with simple linear regression method. This research uses the historical method by conducting research on a source which is then critically analyzed. Data collection techniques are obtained by tracing data and documents that have been stored by agencies including the Ministry of Agriculture, Ministry of Trade, International Rubber Study Group (IRSG), Singapore Commodity Exchange (SICOM), Association of Natural Rubber Producing Countries (ANRPC), Food and Agriculture Organization (FAO), The World Bank, and Gapkindo as well as existing literature and sites. The results obtained are positive trends where each development between countries has experienced a positive price increase, such as, STR 20 has a polynomial line equation Y = 0.0331x2 – 95,28x + 68596, then SIR 20 Y = 0.0231x2 -66,443 + 47966, SVR 20 Y = 0,0301x2 – 86,824x+ 62648, and SMR 20 Y = 0,0279x2 – 80,411x + 58010.

The objective of this study is to contribute to the popularization of knowledge on the earth construction sector by studying the influence of the variation in the quantity of water and the compaction energy on the physico-mechanical properties of a mixture of earth (Avédji clay soil) and coconut plant fibers. · To achieve this, we carried out : · characterization of clay soil and coconut fibers ; · a pre-formulation to achieve good workability and manageability of the soil-fiber mixture (this made it possible to adopt 80% clay soil and 20% coconut plant fibers) ; · the formulation and preparation of soil-fiber mixture samples with two compaction modes: vibration and staking and variations in the quantity of water from 16% to 20% in increments of 2% ; · determination of the mechanical properties of mixtures by compression and tensile tests by bending in the hardened state. The results obtained show that for a water variation of 16% and 20%, the staked specimens give higher compressive strengths than the vibrated specimens; while at 18% the resistances are approximately the same. In traction, the resistance varies in the same direction as the water variation and the addition of fibers makes it possible to improve this tensile resistance by bending. Furthermore, the best mechanical strengths are obtained in traction, which is about 1.00 MPa, and in compression, which is about 1.544 MPa for a water variation of 20% and for compaction energy by staking precisely at compression.

The results obtained show that for a water variation of 16% and 20%, the staked specimens give higher compressive strengths than the vibrated specimens; while at 18% the resistances are approximately the same. In traction, the resistance varies in the same direction as the water variation and the addition of fibers makes it possible to improve this tensile resistance by bending. Furthermore, the best mechanical strengths are obtained in traction, which is about 1.00 MPa, and in compression, which is about 1.544 MPa for a water variation of 20% and for compaction energy by staking precisely at compression.","PeriodicalId":23739,"journal":{"name":"World Journal of Advanced Research and Reviews","volume":"4 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141795742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the relationship between smoking habits, loneliness, and self-esteem among young adults. A sample comprising 144 non-smokers and 103 smokers was assessed using the Rosenberg Self-Esteem Scale, the UCLA Loneliness Scale, and the Fagerström Test for Nicotine Dependence (FTND). Statistical analysis revealed no significant differences in self-esteem and loneliness levels between smokers and non-smokers. These findings suggest that smoking status does not significantly impact loneliness or self-esteem in young adults, challenging common perceptions about the psychological correlates of smoking behavior. Further research is recommended to explore underlying factors and potential mediators in these relationships.

Breast cancer remains a leading cause of mortality among women globally, necessitating accurate and early diagnosis techniques. This study explores the effectiveness of Support Vector Machine (SVM) techniques for diagnosing breast cancer, utilizing the Object-Oriented Analysis and Design Method (OOADM) for system development. The research employed the Wisconsin Breast Cancer Dataset from the UCI Machine Learning Repository, comprising ten features. The dataset was divided into 80% for training and 20% for testing the SVM model. Performance metrics such as classification accuracy, Area Under the Curve (AUC), sensitivity, specificity, and precision were used to evaluate the SVM model, which was also compared against a Decision Tree (DT) model. The results indicated that the SVM model achieved superior performance with an accuracy of 94%, AUC of 98%, sensitivity of 95%, specificity of 87%, and precision of 93%. In comparison, the DT model showed an accuracy of 89%, AUC of 95%, sensitivity of 90%, specificity of 85%, and precision of 90%. The findings underscore the potential of SVM in enhancing breast cancer diagnostic accuracy, thereby supporting early detection and treatment.
