The teeth were divided into 5 equal groups. On the enamel of the removed permanent molars, the Apadent Pro gel was rubbed one time with an angled tip with a rubber nozzle in the first group for 10 s, in the second - 20 s, in the 3rd - 30 s, in the 4th - 50 s, in 5th - 60 s. The teeth were brushed twice a day in the morning and evening for 3 minutes. The calcium content in the surface layer of enamel was determined by the laser spectrometry (I 200 EC Applied spectra) before and after the rubbing of the Apadent Pro gel for 1, 2, 3, 6, 9, 14 days. It was found that the calcium content in the surface layer of enamel increases immediately after the rubbing of the gel in all teeth in proportion to the duration of treatment. The result remains high up to 3 days then decreases in the 1st and 2nd group and by day 14 decreases to the initial level. In the 3rd, 4th and 5th groups, the calcium content in the surface layer of enamel increases significantly, then gradually decreases. On the 14th day of observation, the caries resistance by the Ca/P coefficient is also estimated as high. According to the results of laser spectrometry, the optimal exposure time for the Apadent Pro gel on teeth is equal to 30 seconds. In the surface layer of enamel, the Ca content increases immediately after the rubbing of gel.","PeriodicalId":205170,"journal":{"name":"Atomic and Molecular Pulsed Lasers","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114567570","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}

In this connection, more and more studies address ultraviolet irradiation of seeds and plants as a way to increase their sowing quality. In this paper, XeCl-excilamp (λ~ 300-320 nm) ‒ as a simulator of solar short-wave radiation ‒ is used in the quality of source of ultraviolet radiation. A new data on morphometric and morphological indicators of development of a number of economically valuable crops (parsley, cucumber, pumpkin, zucchini) exposed to XeCl-excilamp are presented. In particular, it is shown that the ultraviolet treatment increases the number of zucchini fruits (\"Tsukesha\" sort) by an average of 40%, compared to untreated control samples and increases the area of the assimilating surface of leafs (in the first week after germination and further in a month and two months) by an average of one and a half times. Compared with the control 90-second treatment of seeds zucchini led to a higher content of vitamin C in fruits and more than a twofold reduction of nitrate to 64±7 mg/kg. Similar results were obtained for the pumpkins. First processing radiation of XeCl-excilamp were subjected parsley seeds. Found processing conditions in which you can increase the yield by an average of 20%. The obtained indicators allow us to draw a conclusion about the economic feasibility of XeCl-excilamp seeds illumination and confirm our conclusions about the prospects of such a procedure for pre-sowing plant seeds.","PeriodicalId":205170,"journal":{"name":"Atomic and Molecular Pulsed Lasers","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115251166","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}

It is known, that oil spills may take place due to leakage of oil from different Oil-Gas-Production Companies and Joint Ventures of the State Oil Company of Azerbaijan Republic. There are 8 Oil-Gas-Production Companies and 4 Joint Ventures in Azerbaijan Republic. Fluorescence spectra were excited by 355 nm line of CFR 200- type laser (QUANTEL) with parameters: diameter of laser beam spot- &diameter; = 5 mm (after collimation- 40 mm); frequency of excitation- f = 20 Hz; pulse duration and power of laser- τ= 7 ns and 60 mJ, respectively. Analysis of differences of the spectral positions of maximums of fluorescence spectra, forms of the emissions spectra, as well as peculiarities of fine structures in emission spectra allowed with a high degree of availability to determine from which Oil-Gas-Production Company of State Oil Company of Azerbaijan Republic (including OGPC “Neftjanije Kamni”) leakage took place on the surface of the Caspian sea and on the earth of Absheron peninsula.
