Adolescent sexuality communication is very important for improved sexual and reproductive health. This study investigated the determinants of patterns of communication on adolescents’ sexuality between parents and in-school male adolescents in Agege local government area, Lagos state, Nigeria. The study employed a cross-sectional survey design and it adopted the purposive sampling with the questionnaire validated.Data collected was analysed using descriptive statistics and inferential statistics.The study revealed that the levels of predisposing factors for knowledge of adolescent at sexuality, both the parents and the adolescent student indicated that among parents, there was good perception about communicating sexuality with parent while only 28.1% of the parents had poor perception. Majority of the respondents (parents and adolescents) reported moderate pattern of communication about sexuality among the adolescents. There was a significant relationship between parents’ knowledge on adolescent’s sexuality and patterns of communication between parents and in-school male and female adolescents in Agege Local Government Area, Lagos State, (p<0.05). There was a significant relationship between parents’ perception on adolescent’s sexuality and patterns of communication between parents and in-school male and female adolescents in Agege Local Government Area, Lagos State(p<0.05). The three environmental factors(peers, media and family support) predicts patterns of sexuality communication between parents and in-school male and female adolescents in Agege Local Government Area, Lagos State, Nigeria. The study therefore recommends that parents should pay more attention to their adolescents’ sexuality issues and be more opened to communicating with them. Parent should communicate more with their male and female adolescents regarding their sexuality.

Wind energy generated by using wind as a fuel is clean and non-polluting as a result it has become more widespread today. However, the uncertainty in the aerodynamic parameters makes the wind energy to cost more. Many researches have been done to increase the wind turbine efficiency, but they fail to consider this uncertain aerodynamic parameters. In this paper an adaptive control technique, which resembles the existing quadratic controller used by the wind industry for variable speed wind turbines below rated power, is designed to reduce the negative effects of this uncertainty. This adaptive controller uses a simple, highly intuitive extremum seeking scheme designed to seek out the optimal gain for maximizing the turbine’s energy capture. The adaptive controller has been tested and validated using MATLAB simulation

This review of literature updates the current outbreak of second wave of coronavirus-2 (SARS-CoV-2) mutant Delta variant (B. 1. 617.2) strain and Delta Plus (AY.1) in India followed by the severe black fungus infections, mucormycosis. The mucormycosis, the black fungus infections have been emerged as an additional threat among those recovering from the viral disease, covid-19. Both coronavirus-2 (SARS-CoV-2) mutant strain, B.1.617.2 (Delta variant) and Delta Plus (AY.1) with black fungus has increased covid-19 hospitalizations and killing people in India. The widely accepted treatment of choice for mucormycosis is Amphotericin B. However, these medicines are already exhausted due to the shortage of supply, found very expensive, and fungal strains are resistant during covid-19 outbreak in India. Therefore, traditional herbal medicines with antifungal properties were used as per Auyverdic guidelines as an alternative therapy for controlling this deadly black fungus, mucormycosis during the outbreak of covid-19. Herbal medicines with antifungal activities are easily available in rural areas, less expensive, and traditional healers are practicing herbal therapy as an age old practice for controlling mucormycosis. Herbal formulations are very common household remedies in the rural parts of India.

The movement of goods and services by road is the only mode of transport in high altitude terrain regions. Most of the large scale transportation is done by trucks and any kind of breakdown, accidents, over loading, reckless driving and not giving way for uphill vehicles results in traffic bottleneck and fatal aftermath. During monsoons the transportation is either halted or more challenging amidst rain, fog, landslides and deteriorated roads. The objective is to design an AI integrated IoT cloud mobile platform to ensure a safe and controlled driving environment.

Since the outbreak of COVID-19 in Wuhan, China, in December 2019, several works have been done and published on the role of environmental factors, especially climate in general and temperature in particular on the spread of the virus, some of which are contradictory. It has also been observed that most mapping has been overgeneralized without identifying the core infection areas. This work creatively uses distribution models to map the spread and infectivity of COVID-19 using biologically relevant temperature variables. We built ensemble COVID-19 global distribution models by fitting the selected temperature variables with over 650,000 occurrence data of COVID -19 across the globe; the ensemble models combined three algorithms: Maximum Entropy (Maxent), Generalized Linear Model (GLM), and Random Forest (RF) and was implemented in R package “SSDM” using a simple average of each SDM and display in Arc Map. Results show that the mean temperature of the coldest quarter (0-15°c) and annual mean temperature (10-22°c) are the main drivers of the virus’s spread. These thresholds defined the level of risk to COVID-19 and were scales between 0 -1, with 0 being low or no risk and one the highest risk. Analysis of the regions at risk by the proportion of areas shows that Western Europe, United States, and mainland China had the most elevated regions under very high risk. At the same time, Africa, except for South Africa and Maghreb nations, was relatively at low risk. Despite few data obtained from Canada, the model predicted a high-risk zone in the eastern provinces of Toronto and Quebec and south of British Columbia. Overgeneralization in mapping was resolved in this work as a high-risk cluster was conspicuously highlighted even in an area of presumably low risk.

The sandstone and conglomeratic sandstone facies of Lokoja and Patti Formation, Southern Bida Basin were analysed for their mineralogical compositions and pebble morphogenesis. The identified framework grains include the dominant quartz grains, feldspars, mica and rock fragments while heavy minerals include Zircon, Topaz, Tourmaline, Staurolite, Sphene, Rutile and Olivene. The heavy minerals were used as indicators of sources of sediments; Zircon and Tourmaline suggest igneous and low grade metamorphic rocks whereas Staurolite and Rutile show high grade metamorphic rocks. The angular to sub-angular shapes of the heavy minerals and sub-angular shapes of quartz grains respectively indicate textural immaturity of the sediments. This is associated with absence or low degree of physical weathering and abrasion due to short distance of sediment transport and it implies the prevalence of chemical weathering of the source rocks. The grain to grain contacts among quartz grains, the occurrence of overgrowths and iron oxide cements are consequences of post depositional changes of the sediments. Interpretation of pebble sizes, sphericity and oblate-prolate index provided information about the paleoenvironments.

One of the most important practices in the financial world is stock trading. The act of attempting to forecast the future value of a stock or other financial instrument listed on a stock exchange is known as stock market prediction. This paper discusses how Machine Learning can be used to predict a stock’s price. When it comes to stock forecasts, most stockbrokers use technical and fundamental analysis, as well as time series analysis. Python is the programming language used to forecast the stock market. In this paper, we propose a Machine Learning (ML) method that will be trained using publicly accessible stock data to obtain intelligence, and then use that intelligence to make an accurate prediction. In this context, this research builds a neural network in TensorFlow and Keras that predicts stock market, which is basically a Python scraper that extracts finance data from the Yahoo Finance platform; more precisely, a Recurrent Neural Network with LSTM cells was constructed, which is the current state-of-the-art in time series forecasting.

The purpose of this research is to determine the direct influence of capital structure, corporate social responsibility, and financial performance on business value, as well as if financial performance acts as a mediating element between capital structure and CSR. This study examines metal industrial sector manufacturing firms that are publicly traded on the Indonesian Stock Exchange through the use of secondary data, data collection, and documentation (IDX). The study sampled 14 businesses using purposive sampling, and the sample comprised 56 financial reports covering four years. Capital structure variables are determined using DER, CSR variables are determined using GRI-G4 principles, financial performance is determined using ROA, and firm value is determined using PBV. To test hypotheses, Path Analysis was employed. According to the findings, capital structure had a positive but minor effect on financial performance, CSR had a significant positive effect on financial performance, and capital structure had a large positive effect on business value. Financial performance has a significant negative effect on corporate value, but CSR has a tiny but favourable effect. Financial performance acts as a buffer between CSR and business value, rather than between capital structure and company value.
