In this study, the simultaneous determination of Co, Cd, Ni, Cu, and Pb was carried out as a color complex with 4-(2-pyridylazo) resorcinol in an aqueous solution under the assesting of machine learning. A partial least-squares multivariate linear regression and artificial neuron network for the analysis of mixtures of metals were developed. MATLAB is a powerful software machine learning program that was used to support matrix calculations and displays.

This modeling is performed on an experimental data set of complexes, where the metal ions of these complexes include transition ion metals and lanthanide ion metals. We use these models to develop a series of new thiosemicarbazone and their complexes; simultaneously, the complexes are worked out the stability constants from the novel models.

Cervical cancer (CC) rates are high in Uganda, yet CC screening rates are very low. Our peer advocacy group intervention, Game Changers for Cervical Cancer Prevention (GC-CCP), was shown to increase CC screening uptake among social network members. In this secondary analysis, we examined mediators and moderators of this effect to better understand how and for whom the intervention was most successful in promoting CC screening.

Dementia seriously threatens the health and quality of life of the elderly and is a burden on families, communities, and society, especially in countries with rapid aging like growing Vietnam. A cross-sectional descriptive study using the EQ-5D-5L quality of life measurement scale on 104 elderly people with dementia was implementend in 6 communes of Thanh Mien district, Hai Duong province.

Understanding the relationship between forest cover and economic development is a challenge for researchers and policymakers in Vietnam. Based on the framework of economic theory and practice in Vietnam, the study used a multivariate linear regression model to assess the economic factors affecting forest cover. The study uses the secondary data period 1990-2017 in Vietnam. Research results confirmed: Rural population and GDP per capita (Low / High economic development level) have an impact on forest cover and these relationships following the shape of Kuznets environmental curves.

This study is an extension of a novel technique to determine interwell connectivity in a reservoir based on fluctuations of bottom hole pressure of both injectors and producers in a waterflood system. The technique uses a constrained multivariate linear regression analysis to obtain information about permeability trends, channels, and barriers. Some of the advantages of this new technique are simplified one-step calculation of interwell connectivity coefficients, small number of data points and flexible testing plan.

Urban transportation infrastructure development projects usually act as a lever for real estate values. This research aims to assess the effects of some projects on urban land prices in three wards of Cau Giay District, namely Quan Hoa, Dich Vong, and Dich Vong Hau wards. With 161 samples surveyed, we established a multivariate linear regression model initially having 11 variables.

In this study, the equations for estimating the number of tropical cyclones (TCs) at a 6- month lead-time in the Vietnam East Sea (VES) have been developed and tested. Three multivariate linear regression models in which regression coefficients were determined by different methods, including method of least squares (MLR), minimum absolute deviation method (LAD), minimax method (LMV).

It is due to the lack of renewable fiber sources for industrial purposes that the need for finding available and alternative material has become imperative. Kenaf (Hibiscus cannabinus L.), a fast-growing industrial crop, would be a potential solution for valorizing salinized lands and/or soils irrigated with saline water.
