In high-temperature geochemistry, it is used to simulate reactions occurring deep inside the Earth, in magma, for example, or to model low-temperature reactions near the Earth's surface aqueous solutions. According to the geological structure, the Kudryashovskoye field is multilayer. The placement system is selective in this field. The development of all facilities takes place using a reservoir pressure system. The well stock for drilling (throughout the field) is 42, including 28 producing wells and 14 injection wells. In 2015, 12 wells were planned to be drilled. The paper considers and analyses two options for the development approach. The first option: drilling, is planned in 2019 according to the approved layout of wells. The density of good grids is 10.6 ha/well. The second option: drilling is carried out according to the areal system with a distance of 200-250 m between the wells. The density of the wells is 8.1 ha/well. It is planned to use the technology for simultaneous-separate operation in 19 wells Modelling is carried out using the Petrel software package. After the work is done and comparative analysis, development options are proposed. The second development option is most suitable from the economic point of view and approach.","PeriodicalId":16365,"journal":{"name":"Journal of Medicinal and Chemical Sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89988075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For ascertaining the reliability of study, data were extracted independently and in duplicate by two investigators. According to some of the conducted studies, environmental exposure to power frequency EMF (electromagnetic field) exposure was found to adversely affect sex hormones, female genital system, embryonic development, pregnancy outcome and fetal and offspring development, while other studies reported no significant effect of power frequency EMF exposure on reproductive parameters and embryonic and fetal development. Overall, the results were not convergent and there was controversy regarding the findings. However, it can be concluded that a part of controversy can be attributed to differences in field strength and exposure time, the experiment condition in terms of in vivo and in vitro which had a significant impact on the observed results.","PeriodicalId":16365,"journal":{"name":"Journal of Medicinal and Chemical Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85134904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simple and well-known model of pharmaceutical carriers is the layered zinc hydroxide (LZH) compound. In the present research, salicylic acid (Sal)-loaded LZH was synthesized using the ion-exchange method. The resulted nanohybrid (Sal-LZH) was characterized using the PXRD, FT-IR spectroscopy, STA analysis, BET, and SEM. Sal anions were intercalated into the interlayer gallery space of LZH, leading to different drug releases at pH 4.8 and 7.4.

Therefore, analyzing these dyes become very important for human health. Tartrazine is one of the commonly used synthetic food dyes and so the development of a new, simple, and accurate separation, preconcentration, and spectrophotometric determination of tartrazine (E 102) was the aim of this work. The method was based on solid-phase extraction by using Diaion SP-207 resin and determination with UV Spectrophotometer. Analytical parameters affecting the recoveries of tartrazine were investigated to find the optimal conditions. The retained tartrazine was removed from the column by 10 mL of 0.01 M HCl in acetone. The recovery values were found as >95%. By this new method, tartrazine contents of various food and medicine samples were determined successfully. TThe recoveries of understudy analytes were found in the range of 93–98%, while the detection limits were calculated in the range of 0.3–2.0 μg L−1.he detection limit was found as 3.52 μg/L.
