The article evaluates the concentration of oil in the atmosphere of Barnaul by an indirect method of measurements which is based on the results of fluorimetric analysis of snow cover. Snow sampling was carried out at the time of maximum snow accumulation in the first decade of March 2013–2017. The concentration of oil in the urban snow cover exceeds the concentration in the control point outside the town by a factor of 2–6, which indicates urban atmosphere pollution. Especially high concentrations of oil are detected at the points located near the intensively loaded urban highways. Analysis sh

Abstract At a number of enterprises, there is a problem of wastewater treatment from oil products. It was studied the oil products composition in the wastewater in industrial sewage system of a machine-building plant. Gravimetric method was used to determine the concentration of oil products in wastewater. When detecting oil products in concentrations exceeding the MPC, it was researched the wastewater treatment from petroleum products by precipitation. It was also calculated the granulometric composition of oil products in wastewater and the main design parameters of the settling tank.

Long-distance pipelines transporting multiple product oils such as gasoline, diesel and jet fuel, are important facilities for transporting fossil energy. One major concern in operation is the energy consumption of the pipeline. Energy consumption should be made optimized tracking batches of oils and cutting mixed oil, which requires an accurate prediction of concentration curve. In engineering, the concentration curve is usually assumed to be symmetric, but it is actually asymmetric, which may lead to estimation errors. Thus, the asymmetric concentration of mixed oil should be studied. The fo

Abstract:
Abstract In the oil and gas industry, carbon steel is widely used in the construction of infrastructure, such as pipelines and tanks, for the transmission and storage of crude oil as well as petroleum products. This is due to its excellent mechanical properties, ease to work with, and low cost. However, it is vulnerable to corrosion. Ionic surfactant type of corrosion inhibitors have been widely applied against pipeline corrosion due to their high mitigation efficiency at low applied concentrations. Corrosion inhibition efficiency is closely related to the inhibitor adsorption mechanism. Howev

Abstract:
Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was

Abstract:
Polymer flooding is one of the most promising EOR methods (Smalley et al. 2018). It is well known and has been used successfully (Pye 1964; Standnes &amp; Skjevrak 2014; Sheng et al. 2015). From a technical perspective we recommend that polymer flooding should be considered as a viable EOR method on the Norwegian Continental Shelf for the following reasons: 1. More oil can be produced with less water injected; this is particularly important for the NCS which are currently producing more water than oil 2. Polymers will increase the aerial sweep and improve the ultimate recovery, provided a prop

Abstract:
Crown rot is a severe postharvest disease affecting tropical and subtropical fruits like mango, avocado, papaya, and banana. It is caused by fungal pathogens that penetrate the fruit, reducing its pulp and leading to premature ripening. Systemic fungicides have been used to control these fungi, typically applied to seeds, leaves, or fruits to prevent disease spread. However, traditional fungicides can pose toxicity risks to the environment and human health. Essential oils are chemical substances that can be found in plants and have antifungal capacity. Essential oils are being investigated as

Abstract:
p-Methoxycinnamic acid (p-MCA) is a cinnamic acid derivative that shows various pharmacologic actions such as neuroprotective and hepatoprotective activities. To examine the insulinotropic activity of p-MCA, the perfused rat pancreas and a pancreatic β-cell line, INS-1 were used in the studies. P-MCA increased insulin secretion from the perfused rat pancreas and INS-1 cells in a concentration-dependent manner. In addition, p-MCA increased intracellular Ca²⁺ concentration ([Ca²⁺]i) in INS-1 cells. The p-MCA-induced insulin secretion and rise in [Ca²⁺]i were markedly inhibited in the absence of

Abstract:
The increasing prevalence of bio-based and biodegradable plastics as an alternative to traditional plastics derived from crude oil is a noteworthy trend. Polybutylene succinate (PBS), a plastic produced from succinic acid, is among the promising materials for the future. However, the production of bio-based succinic acid through biotechnical processes in controlled environments presents challenges. This process leads to increased costs and is currently not economically competitive compared to crude oil-based succinic acid production. In addition to succinic acid, levulinic acid is another mono
