Bouncing inflation in nonlinear gravitational model
We study a gravitational model with curvature-squared and
curvature-quartic nonlinearities. The effective scalar degree of freedom
(scalaron) has a multi-valued potential consisting of a number
of branches. These branches are fitted with each other in the branching and
monotonic points. In the case of four-dimensional space-time, we show that the
monotonic points are penetrable for scalaron while in the vicinity of the
branching points scalaron has the bouncing behavior and cannot cross these
points. Moreover, there are branching points where scalaron bounces an infinite
number of times with decreasing amplitude and the Universe asymptotically
approaches the de Sitter stage. Such accelerating behavior we call bouncing
inflation. For this accelerating expansion there is no need for original
potential to have a minimum or to check the slow-roll conditions. A
necessary condition for such inflation is the existence of the branching
points. This is a new type of inflation. We show that bouncing inflation takes
place both in the Einstein and Brans-Dicke frames.Comment: RevTex 13 pages, 13 figures, a few comments and references adde

Synthesis of the series of new 4-phenyl-5-cyclohexyl-1,2,4-triazole(4H)-3-yl thioacetanilides is described. The key intermediate β 4-phenyl-5-cyclohexyl-3-mercapto-1,2,4-triazole(4H) has been synthesized started from cyclohexane carboxylic acid through its methyl ester, then hydrazide and the corresponding potassium 3-cyclohexyl dithiocarbazate after cyclisation with hydrazine hydrate. The end products 6a-u have been obtained by alkylation of the key intermediate 5 with chloroacetic acid anilides in the presence of basic catalysts. The purity of the compounds synthesized has been monitored by TLC. The structure of compounds synthesized has been proven by elemental analysis data and NMR spectra. In NMR-spectra the result of alkylation has been proven by disappearence of the chemical shift of the mercaptogroup. All compounds β both intermediate 5 and end products 6a-u contain signals of the cyclohexane system protons as two multiplets near 2.80 ppm (CH) and at 1.92-1.11 ppm (CH2)5; 4-aminogroup protons as a singlet signal at 5.92-5.87 ppm. The preliminary prediction of the possible pharmacological activity by computer prognosis (PASS programme) has been carried out. Among activities, which are the most probable for some of the substances synthesized, are ligase inhibitor, interferon agonist, antihypertensive, thyroid hormone antagonist, sedative, antiviral (Pa = 0.554-0.729). Due to prognosis and analysis of logical data the substances synthesized will be examined as possible antiviral agents.ΠΠΏΠΈΡΠ°Π½ ΡΠΈΠ½ΡΠ΅Π· ΡΠ΅ΡΠΈΠΈ Π½ΠΎΠ²ΡΡ

Synthesis of the series of new 4-(1H-pyrrol-1-yl)-5-cyclohexyl-1,2,4-triazole(4H)-3-yl thioacetanilides from 4-amino-5-cyclohexyl-1,2,4-triazole(4H)-3-yl thioacetanilides previously synthesized is described. The target products 3a-z have been obtained by Paal-Knorre pyrrole condensation of the initial aminocompounds 1 with 2,5-dimethoxytetrahydrofuran (2) in the acetic acid medium. The structure of the substances synthesized has been proven by elemental analysis and NMR spectra data. All compounds synthesized contain signals of the cyclohexane system protons as two multiplets in their NMR spectra at 2.39-2.33 ppm (methyne proton) and 1.76-1.13 ppm (cyclohexyl methylene groups protons). Unlike the starting compounds (1) the end products (3a-z) have no signal of 4-aminogroup proton as a singlet in the spectra at 5.87-5.92 ppm. Instead of it, signals of the pyrrole ring are present as two triplets at 7-20-7.17 and 6.32-6.29 ppm. Among activities being more probable for the substances synthesized due to preliminary PASS-prognosis were inhibition of MAO and some enzymes (Pa = 0.554-0.729). Compound (3w) was selected by the National Cancer Institute (NCI) for in vitro screening on different tumour cell lines. As result of this investigation we have noted that, unfortunately, substance 3w is not an effective inhibitor of tumour cells in the dose studied, in particular the growth percent for leukemia cells for more sensitive lines is 68.48 (RPMI-8226); 69.30 (HL-60(TB)); for non-small cell lung cancer β 63.06 (HOP-92); for melanoma β 47.82 (SK-MEL-5); 67.37 (UACC-62); for renal cancer β 56.66 (UO-31). Sensitivity of all cancer cell lines for the colon, CNS, ovarian, prostate and breast cancer was approximately at the control level.ΠΠΏΠΈΡΠ°Π½ ΡΠΈΠ½ΡΠ΅Π· ΡΠ΅ΡΠΈΠΈ Π½ΠΎΠ²ΡΡ

Direct and inverse problems to study the process of ion solutions ltering in porous medium
Solution of actual problem associated with technological process of ltering and dehydrating liquid solutions from ne-dispersed particles is discussed in the paper. Technological process is carried out in the dehydration and puri cation of chemical solutions, drinking water, pharmaceuticals, liquid fuels, products for public use, etc. A mathematical model has been developed to study the process, to determine the basic parameters of the object and the operating modes of the ltering aggregates to make management decisions; this model may take into account di erent operating modes of the ltering aggregate and physical-chemical properties of solutions. In the paper it is noted that when investigating the ltering process, it is rather di cult to determine the main parameters of the object under consideration and their ranges of changes to control the operating objects. Collecting data takes a lot of time; to conduct a series of experiments in laboratory conditions takes a lot of labor power and time; it is di cult to nd the relationship between the parameters of the lter and technological process based on a limited experimental sampling. Urgent problems of determining the basic parameters and their ranges of changes leading to a decrease in the loss of valuable raw materials, an increase in lters performance, an improvement in the quality of the resulting product, etc. are solved in the paper. Based on the analysis of the conducted numerical experiments, conclusions are drawn that serve as the basis for making appropriate management decisions

https://doi.org/10.1093/jipm/pmw010Wheat is an important food security crop in central Asia but frequently suffers severe damage and yield losses from insect pests, pathogens, and weeds. With funding from the United States Agency for International Development, a team of scientists from three U.S. land-grant universities in collaboration with the International Center for Agricultural Research in Dry Areas and local institutions implemented an integrated pest management (IPM) demonstration program in three regions of Tajikistan from 2011 to 2014. An IPM package was developed and demonstrated in farmer fields using a combination of crop and pest management techniques including cultural practices, host plant resistance, biological control, and chemical approaches. The results from four years of demonstration/research indicated that the IPM package plots almost universally had lower pest abundance and damage and higher yields and were more profitable than the farmer practice plots. Wheat stripe rust infestation ranged from 30% to over 80% in farmer practice plots, while generally remaining below 10% in the IPM package plots. Overall yield varied among sites and years but was always at least 30% to as much as 69% greater in IPM package plots. More than 1,500 local farmers-40% women-were trained through farmer field schools and field days held at the IPM demonstration sites. In addition, students from local agricultural universities participated in on-site data collection. The IPM information generated by the project was widely disseminated to stakeholders through peer-reviewed scientific publications, bulletins and pamphlets in local languages, and via Tajik national television
Study of discontinuation issues in the blood service
The article examines the issue of suspension from blood donation and discusses their causes in persons who applied to blood service institutions. It was revealed that for 3 years, on average, 13% of those who applied were not allowed to donate. Of the total ineligible, 10% were temporarily suspended from donating. The main part of them - 8% due to low hemoglobin levels
Slow-roll inflation in (R+R*4) gravity
We reconsider the toy-model of topological inflation, based on the
R*4-modified gravity. By using its equivalence to the certain scalar-tensor
gravity model in four space-time dimensions, we compute the inflaton scalar
potential and investigate a possibility of inflation. We confirm the existence
of the slow-roll inflation with an exit. However, the model suffers from the
eta-problem that gives rise to the unacceptable value of the spectral index n_s
of scalar perturbations.Comment: 12 pages, 3 figures, LaTeX, misprints corrected and references

The aim of the present research was an in silico and in vivo pharmacological study of N-(3,4-dimethoxyphenyl)-2-((2-methyl-6-(pyridin-2-yl)pyrimidin-4-yl)thio)acetamide (Epirimil) as a promising anticonvulsan
Influence of nettle powder addition on bread quality indicators
This article reflects the results of a study on the effect of nettle leaf powder on the physicochemical and organoleptic characteristics of wheat bread. Nettle leaves is a good source of proteins, fibers, minerals and other bioactive compounds and it could be an ideal ingredient for improving the nutritional value of bread and bakery products. Nettle leaf powder was mixed with wheat flour in different ratios: 1 %, 3 % and 5 % to prepare bread samples. The results showed a significant increase in the protein, ash and fiber content of bread. The specific volume of the bread decreased as the level of nettle leaf powder increased due to a decrease in the gluten content of the mixture and due to the interaction between dietary fiber components, water and gluten. Substitutions of 1 %, 3 % and 5 % give parameter values at least the same as the control sample and give acceptable indicators of bread quality in terms of specific volume and organoleptic properties
