A note on some isomorphic properties in projective tensor products

A Banach space X is sequentially Right (resp. weak sequentially Right) if every Right subset of X* is relatively weakly compact (resp. weakly precompact). A Banach space X has the L-limited (resp. the wL-limited) property if every L-limited subset of X* is relatively weakly compact (resp. weakly precompact). We study Banach spaces with the weak sequentially Right and the wL-limited properties. We investigate whether the projective tensor product of two Banach spaces X and Y has the sequentially Right property when X and Y have the respective property.peerReviewe

Dynamical properties of S-gap shifts and other shift spaces

We study the dynamical properties of certain shift spaces. To help study these properties we introduce two new classes of shifts, namely boundedly supermultiplicative (BSM) shifts and balanced shifts. It turns out that any almost specified shift is both BSM and balanced, and any balanced shift is BSM. However, as we will demonstrate, there are examples of shifts which are BSM but not balanced. We also study the measure theoretic properties of balanced shifts. We show that a shift space admits a Gibbs state if and only if it is balanced. Restricting ourselves to S-gap shifts, we relate certain dynamical properties of an S-gap shift to combinatorial properties from expansions in non-integer bases. This identification allows us to use the machinery from expansions in non-integer bases to give straightforward constructions of S -gap shifts with certain desirable properties. We show that for any q∈(0,1) there is an S-gap shift which has the specification property and entropy q . We also use this identification to address the question, for a given q∈(0,1), how many S-gap shifts exist with entropy q? For certain exceptional values of q there is a unique S-gap shift with this entropy

Obesity – the main problem responsible for metabolic disorders

Nicolae Testemitanu State Medical and Pharmaceutical University, Chisinau, Republic of Moldova, The 6th International Medical Congress for Students and Young Doctors, May 12-14, 2016Introduction: The World Health Organization has identified obesity as a global epidemic problem, during the last decades the number of cases, which suffer from it - has grown very fast, as well in our country. It is the most significant cause of damage to the health. It became a public health issue due to the prevalence, costs and its effects. All attention and efforts are geared towards understanding and correcting environmental factors responsible for the increasing prevalence of obesity among the population. Materials and Methods: In this project were investigated 80 persons with obesity. The control group consisted of 20 normal weight persons. Depending on the obesity degree, estimated by calculating the BMIs, the patients were divided in 4 groups: I group - 20 patients with overweight, II group - 20 patients with I degree of obesity, III group – 20 patients with II degree of obesity, IV group - 20 patientswith III degree of obesity. The basal glycemia was dosed by using the gluco-oxidasic method. Analysis of the lipid profile consisted of the determination of total cholesterol (Col), high-density lipoprotein cholesterol (HDL-col), triglycerides (Trig), determining the low-density lipoprotein cholesterol (LDL col) and very- low-density lipoprotein cholesterol (VLDL). The obtained data assessment was performed with the „StatsDirect” statistical program. Results: The analysis shows a high rise of glycemia (p<0.001) along with the increasing degree of obesity and abdominal circumference values (AC). The positive interrelationship of body mass index (BMIs), AC with values of systolic blood pressure (SBP), diastolic blood pressure (DBP) and glycemia, although low, but reliable, attests an existing risk for developing hypertension (HPN) and diabetes in obese patients, which is dependent on the gravity and type of obesity. Comparative research of lipid metabolism parameters in obese individuals attest a considerable increase of TGI, VLDL and decrease of HDL in patients with II and III level of obesity (p=0.05; p=0.002) compared to overweight patients. The cholesterol and of LDL values show a statistically reliable increase in groups of obese patients compared to control group (p<0.0001) but no indicative changes have been registered while performing a comparative research of both groups. It was discovered a highly significant correlation between AC and concentration of Trig, as well as a negative correlation with HDL concentration. Conclusion: Obesity is the main trigger factor, which will lead to HPN increase and impaired carbohydrate and lipid metabolism. The positive correlation of BMIs, AC with the values of SBP, DBP, glycemia, TGI and negative correlation with HDL, although low, but reliable,can cause development of HPN, diabetes and dyslipidemia in obese patients
