Identification of Methane-Bearing Coal Seams in Borehole Sections of the Karaganda Basin Using Geophysical Logging Data

V.S. Portnov · A.V. Golik · G.K. Duganova · N. Khuangan · y 3 más

The Karaganda coal basin is one of the most gas-bearing in the world. Its feature is that there are no large accumulations of free gas in it, while the natural gas content reaches up to 25-30 m³/t; this is confirmed by a large volume of gas sampling, gas logging data, and gas survey data in operating mines. Methane fro...

Study of the mechanism and efficiency of using mineral-organic bleaching-filtering agents in polishing refining

N.I. Boyjanov · Z.R. Kurayazov · B.R. Annazarova · S.M. Jollibekov · y 3 más

In this scientific study, the main objective is to purify vegetable oils stored in the state reserve for an extended period to reach consumable quality based on their physicochemical parameters. In the experiments, polishing refining of cottonseed oils stored for 6 months or longer was carried out. By analyzing the phy...

Mathematical modeling and ecological assessment of fluoride release in a mixture of mineralized phosphorite waste and wastewater from the fat and oil industry

Sh.R. Kurambayev · S.R. Qodirova · S.S. Achilova · A.M. Ollaberganova · y 2 más

This study investigates fluoride loss in a mixture of mineralized mass (MM) extracted from the Central Kyzylkum phosphorite deposits and acidic wastewater (AWW) generated by the fat-and-oil industry. The research aimed to evaluate fluoride release and its retention stability under various conditions. Experimental trial...

Optimization of Aluminum Casting Process Using PLA-Based Casting Patterns and Analysis of their Thermal Behavior

Y.S. Merkibayev · T.A. Chepushtanova · B. Bazarbay · G. Burshukova · y 3 más

This paper presents the results of experimental and numerical studies of the casting process of 99.85% pure aluminum using investment-casting technologies with patterns produced by additive manufacturing. The influence of pouring temperature, mold-filling time, and gating-system design on porosity formation and casting...

EXPLAINING INDONESIA'S RUBBER EXPORT VALUE: THE ROLE OF PRICE, EXCHANGE RATE, PRODUCTION, AND FDI

Rheza Reyhan Narawangsa · Raden Parianom · null Muhammad Rizky Siddiq · null Koh Niak Wu

Natural rubber is a strategic non-oil and gas commodity for Indonesia, acting as a crucial pillar for the national trade balance and the socioeconomic livelihoods of millions of smallholder farmers. However, its export value has exhibited extreme volatility over the past three decades, creating macroeconomic vulnerabil...
