The utilization of biomass waste to produce energy is an alternative to get rid of wastes and also save the environment, charcoal briquette is a significant energy and potential choice to use in households, restaurants, markets and other cooking activities, because, it is very easy and convenient to use. The objective of this study is to research on calorific value of charcoal briquettes in various different material. Therefore, according to the experiments found that, the calorific value results of coconut shell briquettes (CBr1), bamboo charcoal briquette (CBr2), mixed charcoal briquette (CBr3) are 6,682 MJ/kg ,4,880 MJ/kg and 5,433 MJ/kg, and remaining ashes are 77 g, 100 g and 250 g, respectively. Apparently, the coconut shell briquette is more preferable and less remaining ashes on environment than other materials.

The cere fish species (Gambusia affinis) is a small fish, which is 2-3 cm. This fish is a wild fish that fills rivers, ditches and ditches. Cere fish are generally easy to adapt and reproduce. However, the water that irrigates rivers, ditches and ditches often contains community wastes, whether in the form of household waste, laundry, or even oil waste from workshops. So this study aims to obtain the LC5o-72 hour value of waste originating from river waste, laundry, and workshop oil on cere fish mortality. This research was conducted using a completely randomized design experiment. Each waste was treated in 4 treatments with different doses, namely 5 ml/L, 10 ml/L, 25 ml/L, and 50 ml/L for 72 hours with checking every 3 hours, 24 hours, 48 hours, and 72 hours. The results showed that laundry waste had a tolerance limit at a concentration of 10 ml/L and waste oil at a concentration of 25 ml/L.

This study focuses on understanding the influence of financial ratios such as current ratio, capital structure (DER), and Firm Size on the stock prices of consumer goods industry companies from 2015 to 2022. Additionally, the stock prices of these companies will be correlated with inflation. The independent variables in this study include current ratio, capital structure (DER), and Firm Size, while the variables correlated with inflation and the dependent variable are the Stock Prices. The sampling method employed is purposive sampling, gathering a sample of 100 instances from 40 companies. The methodology used involves panel data regression utilizing the Random Effect model. The analysis results indicates that the independent variable Current Ratio significantly affects Stock Prices. However, variables like Capital Structure (DER) and Firm Size do not exhibit a significant influence on Stock Prices. Furthermore, Inflation has a significant negative impact on Stock Prices.

Sokoto state is been challenged with diverse array of problems such as food insecurity, malnutrition, poor healthcare. Thus, the need to search for locally available plant materials is intensified. The objective of this work was to conduct a phytochemical, proximate and Na, K, Ca, Mg, Cu, Zn (minerals) analysis of eucalyptus (Eucalyptus globulus) and gingerbread plum (Noecarya macrophylla) leaves using standard methods and materials of analytical grade. The proximate results revealed moisture of (7.10 ± 09), (7.73 ±0.3) ash (14.76 ± 0.2) (12.85 ± 0.11), crude lipid (1.38± 0.007) (1.46 ±0.02), crude fibre (2.42 ± 0.03) (2.54 ± 0.03), crude protein (5.66 ± 0.04) (7.3 ± 0.006), carbohydrates (68. 68 ± 0.31) (68.12 ± 0.23) for gingerbread plum and eucalyptus respectively. The minerals in gingerbread plum and eucalyptus respectively are as follows; zinc (0.59± 0.06 ppm).4 ± (0.005 ppm), calcium (11.38 ± 0.6 ppm) (19.48 ± 0.53 ppm), potassium (7.21 ± 1.2 ppm) (5.10 ± 0.93 ppm), copper (0.51 ± 0.007 ppm) (0.19 ± 0.04 ppm), magnesium (3.74 ± 0.41 ppm), (10.9 ± 93 ppm), sodium (7.65 ± 0.63 ppm) (12.21 ± 0.32 ppm). Phytochemicals determined include, alkaloids, saponins, tannins, phenols, and phytate. The results have revealed that, the two plants are rich in proximate, phytochemicals and minerals and can be useful for consumption.

We have analyzed the application of vectors in cardiology and the way cardiac vector theory analyzes the heartbeat and can explain the entire cardiac conduction vector relationship and the Enthoven equilateral triangle hypothesis. This sheet explains the principles of the electrocardiogram and the interpretation of the waveforms. ECG can be called an electrocardiogram, which is a process of producing electrical activity through repetitive cycles. This diagram shows the voltage and duration of electrical activity by placing electrodes on the skin. Vector cardiography ( VCG) is a procedure that creates a 2D image of the heart's electrical activity by monitoring the spatial location of ECG waves at each successive point in their period. Even in the 21st century, coronary heart disease still represents a serious threat to humans and a major challenge to the scientific community. The most important elements for understanding and interpreting the ECG are the Enthoven triangle and the cardiac vector hypothesis, which have the potential , saving millions of lives when used quickly and appropriately to treat patients.

The body of literature on concrete using mineral admixtures covers a number of review studies on the durability characteristics of various materials used in concrete, such as fly ash (FA), rice husk ash (RHA), ground granular blast furnace slag (GGBS), fly ash (SF), and met kaolin (MK) are reviewed in this work. The features that are related to durability have been evaluated, and they include permeability, resistance to chloride ion penetrations, abrasion, fire resistance efflorescence. Incorporating mineral admixtures in concrete affects various properties. Concrete's permeability decreases and its ability to resist chloride ion penetration rises when admixtures containing a greater alumina content are used. Use of mineral admixtures enhances compressive strength and enhancing abrasion resistance. Moreover, highly reactive mineral admixtures mitigate efflorescence. Notably, while heating PFA concrete improves fire resistance, it reduces overall durability. SF concrete, on the other hand, behaves similarly to standard concrete but can be more brittle. MK concrete exhibits increased strength at 200°C, but its durability and strength decline at higher temperatures compared to other concrete types.RHA pozzolans can replace OPC up to 15% by weight after curing for up to 200 days without lowering the concrete's compressive strength.
