Borel-Cantelli sequences
A sequence in is called Borel-Cantelli (BC) if
for all non-increasing sequences of positive real numbers with
the set
has full Lebesgue measure. (To put it informally, BC
sequences are sequences for which a natural converse to the Borel-Cantelli
Theorem holds).
The notion of BC sequences is motivated by the Monotone Shrinking Target
Property for dynamical systems, but our approach is from a geometric rather
than dynamical perspective. A sufficient condition, a necessary condition and a
necessary and sufficient condition for a sequence to be BC are established. A
number of examples of BC and not BC sequences are presented.
The property of a sequence to be BC is a delicate diophantine property. For
example, the orbits of a pseudo-Anosoff IET (interval exchange transformation)
are BC while the orbits of a "generic" IET are not.
The notion of BC sequences is extended to more general spaces.Comment: 20 pages. Some proofs clarifie
Influence of the autonomic nervous system on the clinical course of overactive bladder
Overactive bladder (OB) is a disease which is very easily diagnosed, but presents considerable difficulties in the choice of treatment mode. At present the specialists turn their attention to this syndrome due to a wide spread of the disease, its negative impact on quality of life, social and economic importance. Pathogenesis of OB is complex. Thus, under conditions of urothelium atrophy which takes place because of estrogen deficiency in postmenopausal women, in violation of its GAG protective layer, barrier function of urothelium are violated, which leads to its damage. The appearence of urination disorder symptoms are
associated with the fact that atrophic mucosa of urethra and triangle of bladder are hypersensitive to even minimal portions of urine. Aging process also play a role
in OB development including lowering ability of tissues to repair, their elasticity reduction, increased apoptosis and cell atrophy, degeneration of nerve endings, smooth muscle tone change, deterioration of urothelium and its GAG protective layer. It can be a result of manifestation of bladder outlet obstruction that causes OB symptoms in men suffering from benign hyperplasia, prostate cancer and chronic prostatitis
Effects of divalent dopants on the microstructure and conversion efficiency of Cr4+ ions in Cr,Me:YAG (Me β Ca, Mg, Ca/Mg) transparent ceramics
The efficiency of Cr4+:YAG is directly proportional to the transparency and concentration of Cr4+ which can be tuned by changing the divalent dopant. The aim of this study was to investigate the influence of different kinds of divalent dopants on the properties of Cr,Me:YAG (Me = Ca, Mg or Ca/Mg) ceramics made by solid-state sintering in vacuum. Pure YAG phases with an in-line transmittance of 80% at 1064nm were prepared. It was revealed that the Cr4+ concentration is directly proportional to the concentration of divalent dopants and it does not depend on the type of dopant. Our experiment proves that the efficiency of high optical quality Cr4+:YAG ceramics preparedby sintering does not change when different kinds of divalent additives are used
Application of Mock-Court as an Interdisciplinary Model for Consolidation of Professional Training of Law Students
This study deals with solving the current problem of pedagogy of high school β consolidation of theoretical and practical approaches to ensure the quality of professional training of law students. According to the author, the introduction of simulation modelling technologies in training courses allows enhancing interdisciplinarity in teaching, which is an important way of meeting the dynamic needs of students in close connection of theoretical and practical blocks of professional training of future specialists. The experience of the American Bar Association on the future of legal education has suggested the idea of applying mock-court as interdisciplinary models. Experimental application of mock-court was tested in the courses βCriminal Lawβ and βCivil Lawβ, which are part of the block of special disciplines of the educational and professional training program in specialty 081 βLawβ. Mathematical data processing and STATA software were used to analyse the results obtained and to objectively consider the dynamics of changes in personality-organizational, operational-activity, cognitive-competence, personality-motivational, information-technological, linguistic-communicative components. The study showed the effectiveness of the use of mock-court on the development of all components of the readiness of law students for professional socialization. The authors concluded that the application of mock-court in the professional training of future lawyers contributes to feedback increasing studentsβ educational motivation and allows monitoring of changes in student development. This model can be applied to enhance interdisciplinarity in the teaching of other courses of the block of special subjects of professional training of lawyers
Features of microbiological diagnosis and choice of selective antibiotic therapy in patients with acute cholecystitis
The objective: to improve the results of destructive forms of acute cholecystitis (AC) surgery by the development of antibiotic therapy algorithm and taking into account the severity of the disease according to Tokyo guidelines (2013). Materials and methods: 266 patients having been operated on for AC made up a treatment group and 203 patients - the control one. In 234 treatment group patients microfloraβs bacteriological study was carried out and its selective sensitivity to antibiotics was determined. Results and discussion. The AC treatment group patients (n=266) were arranged according to Tokyo guidelines (2013) into 3 grades. Mild course (grade I) consisted of 29 patients (11%), microbiological studies were not conducted. Antibiotic prophylaxis with beta-lactam antibiotics was used. At moderately severe AC (grade II, n = 200, 75%) escalation antibiotic therapy was carried out. At severe disease (grade III, n = 37, 14%) de-escalation antibiotic therapy was performed. Bacteriological studies were conducted in 237 patients with destructive forms of AC, at that 531 microflora isolates were cultured. Intestinal group microorganisms were the most frequently cultured. Beta-lactam antibioticsβ sensitivity was prevailing and constituted 83.3%. The number of suppurations in the treatment group decreased from 9.8% to 4.3%, and mortality rate decreased from 1.48% to 0.75% (
Echinococcosis at urology. Pelvic parasitic cyst. Case report
Introduction. Echinococcosis is a serious chronic parasitic disease. Early diagnostics and patients` treatment with echinococcal lesions is an up-to-date problem.
Objective. The aim of the article is to present the clinical case of diagnostics and treatment of the patient with urological complications caused by parasitic echinococcal pelvic cyst.
Clinical case. The article highlights the features of diagnostics and treatment of urological complications of pelvic echinococcal lesions. The patient was operated in volume: "Laparotomy. Resection of parasitic cyst of small pelvic cavity. Echinococcectomy of the liver, abdominal cavity, retroperitoneal space." The peculiarities of operation was highlighted. The postoperative period lasted without complications.
Conclusions. The demonstrated clinical case points out the necessity of the dispanserisation, early diagnostics and special helminth treatment of the patients living in the endemic regions. It allows to prevent the appearance of the echonococcosis advanced cases that lead to the reoperations and frequent patients` disability
CERN as an international scientific collaboration
It's not a secret that scientific development has been much faster recently, first of all because of booming information technologies, as they dictate the world what it should be in the next moment. Everything changes, including approaches to scientific research. That is why nowadays such phenomenon as scientific collaborations have become very popular. In this article, the authors derive the definition of a scientific collaboration compiled on the basis of various approaches applicable to collaborations. The example of the major scientific collaboration of CERN (European Center for Nuclear Research) emphasizes the importance of each aspect in the derived definition and concludes that the unambiguous definition of the scientific collaboration is further applicable in further fundamental studies of this phenomenon

Topicality. The metabolic syndrome is pathogenetically interrelated metabolic disorders in the condition of a sick person. A large set of factors is involved in its occurrence. Risk factors include genetic predisposition, overeating, insulin resistance, obesity, bad habits, hypodynamics, stress and unfavorable environmental conditions. First of all, defects of the lipid and carbohydrate metabolism provoke a cascade of genetic, metabolic, hormonal, nervous, inflammatory and other reactions and disorders in cells, tissues and organs, causing the metabolic syndrome and associated diseases, such as diabetes, kidney and gallstone disease, hypertension, platelet hyperaggregation, etc. Therefore, the rational use of synthetic and herbal medicines in the complex correction of these disorders can slow down the development of the metabolic syndrome.
Aim. To develop the method for obtaining a dry modified extract from bearberry, study its chemical composition, hypoglycemic and hypolipidemic activity in order to determine the prospects of its use for the correction of the metabolic syndrome.
Materials and methods. The study object was a dry extract of bearberry leaves modified with cysteine. HPLC and spectrophotometry were used to analyze the extract obtained. The hypoglycemic and hypolipidemic activity of dry extracts of bearberry was studied in rats with insulin resistance.
Results and discussion. The method for obtaining a dry modified extract from bearberry leaves was developed by adding cysteine. Phenologlycoside (arbutin), 2Β phenolic acids (gallic and ellagic), 6Β flavonoids, 8Β saponins were identified in the extract, and their quantitative content was determined. Hyperoside and catechin were dominant among flavonoids, and ursolic acid, uvaol, and lupeol prevailed among saponins. The content of the main groups of phenolic compounds was determined in the extract by spectrophotometry. The introduction of the dry extract from bearberry leaves modified with cysteine has a normalizing effect on metabolic disorders on the background of a high-fructose diet; therefore, it can be a promising agent for the correction of the metabolic syndrome.
Conclusions. As a result of the research conducted, a new dry extract from bearberry leaves modified with cysteine has been created. The phytochemical composition, hypoglycemic and hypolipidemic activities of the extract have been studied, indicating the prospects for its use to correct the metabolic syndrome.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ.

Toxicity bioassay of waste cooking oil-based biodiesel on marine microalgae
The world biodiesel production is increasing at a rapid rate. Despite its perceived safety for the environment, more detailed toxicity studies are mandatory, especially in the field of aquatic toxicology. While considerable attention has been paid to biodiesel combustion emissions, the toxicity of biodiesel in the aquatic environment has been poorly understood. In our study, we used an algae culture growth-inhibition test (OECD 201) for the comparison of the toxicity of B100 (pure biodiesel), produced by methanol transesterification of waste cooking oil (yellow grease), B0 (petroleum diesel fuel) and B20 (diesel-biodiesel blended of 20% biodiesel and 80% petroleum diesel fuel by volume). Two marine diatoms Attheya ussuriensis and Chaetoceros muelleri, the red algae Porphyridium purpureum and Raphidophyte Heterosigma akashiwo were employed as the aquatic test organisms. A sample of biodiesel from waste cooking oil without dilution with petroleum diesel (B100) showed the highest level of toxicity for the microalgae A. ussuriensis, C. muelleri and H. akashiwo, compared to hexane, methanol, petroleum diesel (B0) and diluted sample (B20). The acute EC50 in the growth-inhibition test (96 h exposure) of B100 for the four species was in the range of 3.75β23.95 g/L whereas the chronic toxicity EC50 (7d exposure) was in the range of 0.42β16.09 g/L
