This goal is achieved by the fact that measuring is made using a capacitive sensor of volumetric soil humidity simultaneously with the measurement of SER using a 4-electrode F.F. Wenner array. Based on the analysis of literary and own data equations for adjusting SER against the background of different volumetric humidity and soil porosity are proposed. Further refinement of SER measurement results can be achieved by including in the equation the parameters related to the cation-exchange capacity (CAC) of the soil, namely the content of organic matter and clay particles. It is suggested that it is possible to determine expressly the latter using color-gauge (RGB) sensors.","PeriodicalId":23657,"journal":{"name":"Vestnik Farmacii","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89131868","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}

Nonlinear nature of SER dependence on the electrodes immersion depth was established. For non-insulated electrodes the dependence was well approximated by the power function regardless of the method of calculating geometric coefficient of installation. In case of partially isolated (point) electrodes the use of geometric coefficient for calculating geometric coefficient with an adjustment to the electrodes immersion depth into the substrate studied makes it possible practically to get rid of SER dependence on the electrodes immersion depth. The technique can be used to assess the soils trophicity in places where medicinal plants grow.","PeriodicalId":23657,"journal":{"name":"Vestnik Farmacii","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77699811","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}

An analysis of macronutrients content (potassium, sodium, magnesium, calcium, phosphorus, sulfur and iron) and its components in a pectoral species №4 was carried out using the atomic emission spectrometry. It was found out that the content of macronutrients is in the range of 62,1-21705,63 mg/kg. Their average values decreased in the series: K> Ca > Mg > P > S > Na > Fe. Macronutrients appear in the amount of 10 to 80% in the infusion from the pectoral species № 4. The amount of potassium, sodium, magnesium, calcium, phosphorus, sulfur and iron in the pectoral species № 4 made 25-1100% of the daily requirement which allows to consider this species as an additional source of those macronutrients presence in the human body.","PeriodicalId":23657,"journal":{"name":"Vestnik Farmacii","volume":"51 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75145080","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}

When developing the composition and technology of tablets and hard capsules based on a red raspberry leaves dry extract it was proposed to produce tableted and powder mass using wet granulation and direct compression. To develop the composition of tablets and hard capsules using wet granulation the method of mathematical planning of the experiment was used: Latin square 3x3. The influence of the following factors on the quality of the obtained tablets and the contents of hard capsules was studied: disintegrating agents, excipients, concentration of binder solution. Disintegration time and compressive strength of tablets were used as optimization parameters and flowability of the powder mass for hard capsules was also evaluated. Significant effect on tablets disintegration of factors A and B (the nature of the excipient and the disintegrant) was stated. Duncan's multiple rank test was used to propose preference series within these factors. Compressive strength of tablets was not influenced by any factors studied. Based on the studies carried out the composition of the tablets and the contents of hard capsules with the use of wet granulation was proposed. The development of the composition and technology for obtaining tablets and the contents of hard capsules by direct compression and without wetting and granulation, respectively was made. It is proposed to use microcrystalline cellulose, lactose monohydrate and silicon oxide as additives to make direct compression which will improve technological characteristics of the tablet and powder mass and make it possible to produce tablets and the contents of hard capsules by direct compression and without wetting and granulation. This, in turn, will contribute to an increase in the microbiological purity of the tablets and the contents of hard capsules and increase labor productivity during their production. To increase the stability of tablets based on dry extract of red raspberry leaves water-soluble film coating is proposed.","PeriodicalId":23657,"journal":{"name":"Vestnik Farmacii","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82697891","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}

The influence of the difference in hydrostatic pressure at the inlet and outlet of the quartz capillary and the difference in the approach to the analysis when changing the base electrolyte are investigated. The influence of the sample injected zone length on reproducibility of assay results of procaine hydrochloride has been studied. In order to improve separation efficiency and reproducibility of quantitative analysis results it is recommended to replace the base electrolyte after each analysis, as well as to inject the sample avoiding short injection values and high pressure. The values of apparent mobility of the test substance which can be used in the development of methods for procaine hydrochloride assay by capillary electrophoresis are calculated.
