Study of the lineshape of the chi(c1) (3872) state
A study of the lineshape of the chi(c1) (3872) state is made using a data sample corresponding to an integrated luminosity of 3 fb(-1) collected in pp collisions at center-of-mass energies of 7 and 8 TeV with the LHCb detector. Candidate chi(c1)(3872) and psi(2S) mesons from b-hadron decays are selected in the J/psi pi(+)pi(-) decay mode. Describing the lineshape with a Breit-Wigner function, the mass splitting between the chi(c1 )(3872) and psi(2S) states, Delta m, and the width of the chi(c1 )(3872) state, Gamma(Bw), are determined to be (Delta m=185.598 +/- 0.067 +/- 0.068 Mev,)(Gamma BW=1.39 +/- 0.24 +/- 0.10 Mev,) where the first uncertainty is statistical and the second systematic. Using a Flatte-inspired model, the mode and full width at half maximum of the lineshape are determined to be (mode=3871.69+0.00+0.05 MeV.)(FWHM=0.22-0.04+0.13+0.07+0.11-0.06-0.13 MeV, ) An investigation of the analytic structure of the Flatte amplitude reveals a pole structure, which is compatible with a quasibound D-0(D) over bar*(0) state but a quasivirtual state is still allowed at the level of 2 standard deviations
RUBY ROMAN GRAPES
Grapes are the most important crop. The fruits of grapes are widely used throughout the world. The main indicators that characterize the quality and value of grapes are the sugar content, namely, glucose and fructose. Grapes contain many vitamins, especially it is dominated by B vitamins. Also, the grapes are filled with organic acids, trace elements, and a high content of minerals. It is cultivated in almost all continents of our planet. Varietal variety of grapes is very large. Most varieties recorded in France, then in the Russian Federation, the United States, Italy, Turkey, Spain, Germany. However, Japanese breeders have bred a variety that has become the most expensive in the world. Currently, ecological viticulture is most developed in the United States, Japan, Brazil, Germany, Italy, Spain, France and other European countries
Non-carcinogenic risk for children population health in kazan caused by food products and food raw materials contamination
The paper dwells on results of assessing non-carcinogenic risk for children health in Kazan caused by consumption of food products contaminated with chemicals. Research was performed in two stages (2007–2010 and 2011–2014) on children aged 3–6. Actual nutrition of children was examined via questioning and timing-weighing techniques. Daily doses were calculated allow-ing for regional exposure parameters at median (Me) and 95-th percentile level. We detected high non-carcinogenic risk at 95-th percentile level for methyl-mercury (3.89 and 3.33 in both periods correspondingly); high and intolerable for As (10.67 in the first period). We determined organs and systems in a body which were under greatest toxic effects. Alerting level of non-carcinogenic risk for central nervous system (HI = 3.03) was detected in the first period at median level. In 2007–2010 we detected the following high non-carcinogenic risks at the 95-th percentile level of a danger coefficient for children: non-carcinogenic risk for central nervous system (HI = 12.20), hormonal system (HI=12.87), immune system (HI=11.72), and alerting risk for development (HI=4.03). In 2011–2014 the following systems were most prone to overall toxic impacts: central nervous system and development (HI = 4.02 and 3.98 correspondingly). Non-carcinogenic effects risk over 2007–2011 for hormonal system (64 %), central nervous system (79 %), and immune system (91 %) was caused mostly by food products contamination with As. As for 2011–2014, the greatest risk factor was Pb introduction, (46 %) for hormonal system, and (57 %) for central nervous system
City Soil Ranking According to the Level of Pollution: Approach Based on the Health Risk Assessment of the Child Population
© 2020 Published under licence by IOP Publishing Ltd. Assessment of soil pollution with chemicals in certain districts (zones) of the city of Kazan was performed according to the data of the social-hygienic monitoring of the FBHI "Center of Hygiene and Epidemiology in Republics of Tatarstan" for the period of 2010-2016. The indices of complex assessment of soil pollution with heavy metals (HM) and oil products in the zones under study did not exceed the established regulations. The results showed uneven distribution of pollutants on the territory of the city zones. The 3-rd zone (the Vakhitovsky district) is different, there the major contribution to the total risk level is made by lead (Pb)-51.4%, cadmium (Cd)-36.9%, mercury (Hg)-3.53%, oil products, and copper (Cu)-2.6%. The level of non-carcinogenic risk for the health of the child population aged 3-6 years old with application of regional exposure factors (THI 1.0 and less) corresponds to the target risk level. The maximum contribution to THI is caused by the dermal route of the oil products' entry (from 94.0 to 98.9 %). Ranking of the city territory according to the total hazard quotient with the account of all routes of the chemicals' entry identified two zones ranking first in the risk level: the 2-nd zone (the Sovetsky district) and the 3-rd zone (the Vakhitovsky district). The results indicate the necessity of revising the approaches to assessment of possible health risks associated with oil hydrocarbons on the basis of new scientific data
Risk assessment of pesticide intake with local food products for adult health of the city of Кazan
© 2020, Editorial board of Journal of Experimental Biology and Agricultural Sciences. All rights reserved. The current study was carried out to access the effect of DDT and HCH contaminated local food consumption on the adult population of Kazan city. Unexpectedly, the computations considered outcomes for a wide range of food items that are covered by the dietary admission model have hazard appraisal. The degrees of non-cancer-causing hazards for the strength of the grown-up populace related with the complex entry of DDT and HCCH at the median (Ме) level and the level of the 95th percentile with the basic food groups are identified. The ongoing dietary danger evaluation and at the degree of the 95th Percentile showed that the likelihood of Tatarstan inhabitants being presented to pesticide buildup levels that could prompt high (HI =13.41) negative wellbeing results. Such high levels of risk need urgent actions on the decrease of pesticide concentration and imply the development and implementation of planned curative measures
