The study features of bone tissue mineral density and their correlation with blood levels of calcium, magnesium and non-organic phosphorus in young pregnant women. Clinical and ambulatory examination of 120 pregnant women of ages 1625 was made. Estimation of bone tissue mineral density and blood levels of calcium, phosphorus and magnesium was performed during the pregnancy stage of 12 to 28 wee...

Mineral malnutrition stemming from undiversified plant-based diets is a top global challenge. In C3 plants (e.g., rice, wheat), elevated concentrations of atmospheric carbon dioxide (eCO2) reduce protein and nitrogen concentrations, and can increase the total non-structural carbohydrates (TNC; mainly starch, sugars). However, contradictory findings have obscured the effect of eCO2 on the ionome...

An open problem for Distributed Information Retrieval is how to represent large document repositories (known as resources) efficiently. To facilitate resource selection, estimated descriptions of each resource are required, especially when faced with non-cooperative distributed environments[1]. Accurate and efficient Resource description estimation is required as this can have an affect on reso...

The economic value of a mineral resource is highly dependent on the accuracy grade estimations. Accurate predictions grades can help businesses decide whether to invest in mining project and optimize operations maximize resource. Conventional methods predicting gold resources are both costly time-consuming. However, advances machine learning processing power making it possible for estimation be...

The overall economic performance is summarised in the growth. It occurs when resources are combined technically an effective way. While advanced countries have no reliance on natural resources, they experience steady growth compared to resource-abundant countries. Caspian Sea basin (Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan) Central Asia states (Kyrgyz Republic, Tajikistan, Uzbekis...
