Published: July 2024

Abstract
Spray quenching (or jet impingement) is the most common technique employed to improve the uniformity of heat removal and break the vapor layer, allowing for a high cooling rate to be achieved. This article presents the heat transfer characteristics of quenching a hot surface, which can be expressed by the boiling and quench curve. It discusses three major spray parameters that have a substantial role in the quantification of spray cooling performance: droplet size, droplet velocity, and volumetric flux. The article also presents the available models and correlations to predict the cooling rate in spray quenching of hot surfaces during different boiling phases. It then discusses the effect of surface roughness on spray cooling performance.

The beef cattle sector produces waste in the shape of cattle feces, which has yet to be effectively utilized. The farming sector produces waste in the shape of rice straw, but the processing has not been varied. The making of eco enzymes is one of the new ways to process beef cattle feces and rice straw into more useful. The research sought to examine how adding molasses affects the fermentation process of eco-enzymes derived from beef cattle feces and rice straw filtrate. The eco-enzymes were obtained from solid fermentation and liquid fermentation processes. Solid-state fermentation was conducted over a period of seven days, followed by the extraction procedure. The extracted filtrate was fermented facultatively anaerobic for 21 days. The research uses an experimental approach utilizing a completely randomized design or CRD there are 3 treatments, which is the addition of molasses at a dose of P1 = 2.5%, P2 = 5%, and P3 = 7.5%, each repeated 6 times. Data were processed using the ANOVA test and using Tukey’s test for further analysis. The results showed that molasses dosing had a significant effect (P<0.05) on reducing the pH value to 3.34 - 3.68, producing total Lactic Acid Bacteria (LAB) 6.76x105 - 14.13x 105 CFU/ml, and alcohol content 6.12 - 13.69%.

ABSTRACTLiquid organic fertilizer (LOF) is proven to be more effective than solid organic fertilizer because nutrient mineralization is more efficient, so nutrients are quickly available for plants. Water hyacinth, as a water weed, turns out to have many functions. Besides being able to become a biofilter by absorbing chemical compounds in polluted water, the accumulation results also contain mineral compounds that are useful for increasing plant yields. Therefore, it is necessary to review the results of applying LOF made from water hyacinth to cayenne pepper plants. This study aims to analyze the effect of various doses of water hyacinth extract on the yield of cayenne pepper. This study uses a non-factorial experimental method, a complete random design (CRD), with an analysis model of LSD test (Least Significant Difference Test) α 5%. There are 4 treatments, namely, 0 ml, 40 ml, 60 ml, and 80 ml, with 5 replications. The parameters observed are the number of fruits, the fruit weight, and the wet weight of the plant. The results showed that the water hyacinth LOF has a pH of 7, doesn’t sting, and is light brown. The best treatment for P3 or 80 ml of water hyacinth POC is that the average number of fruits is 10 seeds, the average weight of fruit is 2.04 grams, and the average wet weight of plants is 46.9 grams.

In this life, humans from birth until now always experience changes, both physically and mentally, both negative and positive changes. These changes are nothing but the result of human work, creativity and initiative which always develops and progresses over time. In broken households, some teenagers often experience mental depression (mental pressure), so that teenagers are not comfortable living in their families, which usually has an impact on teenagers' poor social behavior or giving rise to various forms of delinquency, Not all teenagers can go through their development process and develop well, if there is no full support from internal and external factors that influence their development. A large number of teenagers experience failure in achieving their developmental tasks, one of which is falling into juvenile delinquent behavior. This research uses a library research approach, in the form of research with objects in the form of library works, especially scientific journals, books, articles and information obtained via the internet. And from the results of the research, it was found that teenagers who experienced broken homes had a damaged mentality and experienced forms of bad behavior and various forms of delinquency that they committed. And this research also aims to describe the forms of mental health and delinquency in adolescents in broken home families.

Authors: Chaparro Pesca Jorge Alberto , Niño Alejandro , Niño Gustavo Enrique 
Published: July 2024

Objetivos: Desde el inicio de la pandemia en 2019, los productos básicos de la canasta familiar en Colombia, ha experimentado variaciones históricas significativas. En este sentido, durante el año 2022 los precios de la papa contribuyeron con un 19.52% a la variación total del Índice de Precios del Consumidor (IPC). En este artículo, se analiza si estas variaciones se deben en parte a un comportamiento especulativo en los precios de la papa desde el inicio de la pandemia Covid19. Métodos: Se emplearon cuatro métodos diferentes de estimación de series de tiempo para probar que si la inestabilidad ha persistido en los últimos dos años, creando una volatilidad en los precios. A su vez se utilizaron modelos de Supremum Augmented Dickey-Fuller y Generalised Supremum Augmented Dickey-Fuller para probar tendencias especulativas. Resultados: Los resultados muestran que la serie dejo de ser estacionaria después de la pandemia y que hay tendencias especulativas en los precios lo que sugiere que no solo los eventos externos han contribuido al aumento en el precio de la papa y, por ende, al incremento del IPC. Conclusión: La pandemia de 2020 fue un evento histórico que afectó las cadenas productivas de los países en múltiples formas. En Colombia, la cadena productiva de los commodities agrícolas fue afectada principalmente por los cierres de las regiones y por la falta de abastecimiento de alimentos al inicio de la pandemia. Los resultados indican que los precios tuvieron un comportamiento explosivo en 2020, que pudo haber sido aprovechado para comportamientos especulativos. Se proponen tres frentes de política pública para mejorar la situación del mercado: La necesidad de crear sistemas de inventarios para el producto agrícola, la inclusión de herramientas financieras que permitan tener mejores expectativas del futuro, y la urgencia de mejorar la productividad del sector.

In modelling and simulating future rainfall for a selected location, the probability distributions have been established to be an effective tool. In this study, the different methods utilised in the estimation of the probability distributions’ parameters were evaluated and presented using Weibull's two parameters. Different estimator methods (mean rank, median rank, symmetric, graphical, least square, empirical, maximum likelihood, general probability, modified maximum likelihood, Mabchour, alternative maximum likelihood, equivalent energy, moment expression, Lysen and Moment methods) were used to determine probability density function, reliability, reliability index and failure functions of rainfall data from Maiduguri. The performances of these different methods were compared probability density function, reliability, reliability index and failure functions of Weibull two parameters. The study revealed that the values of probability distribution dimensionless shape variables were between 1.0193 and 4.205, and probability distribution scale factor constants were between 0.302 and 7.254. These values are all positive (non-negative values or less than zero) values. It was established that there were significant differences (F108, 1728 was 162.1976 and the probability (p) was zero) between the individual reliabilities and Weibull estimators (F15, 1620 was 14928.98 and probability was zero) at a 95 % confidence level (p less than 0.05). It was concluded that caution must be taken in the utilization of general probability, equivalent energy, Alternative Maximum Likelihood Method and moment expression methods in any engineering applications to prevent failure of devices or infrastructure.

Published: July 2024

This paper proposes an inverse two-parameter Lindley distribution by utilizing the one and two parameter Lindley distributions. The key properties of the novel distribution like, its survival function, shape characteristics of the density, entropy measure, hazard rate function, stochastic ordering and stress-strength reliability were examined. Two data sets were employed in the empirical studies. Method of maximum likelihood was used to estimate the parameters. The goodness- of -fit was accessed using the HQIC, BIC, CAIC, and AIC. The proposed distribution was compared with the inverse Lindley and the inverse Akash distributions in order to access its superiority over the two distributions. Ultimately, the new inverse two parameter Lindley distribution was found to be superior by providing a better fit.
