When the degree of intersections A∩B of events A,B is unknown arises a problem: how to evaluate the probability P(A ∩ B) and P(A ∩B) from P(A) and P(B). To treat related problems two models of valuation: interval and paired probabilities are proposed. It is shown that the valuation corresponding to the set operations ∩ (intersection), ∪ (union) and ∼ (complement) can be described by the truth f...

An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to 3-nitro-2H-chromenes for the synthesis of chiral heterocyclic systems containing both chroman and pyrazolone derivatives has been developed. This reaction afforded the desired products in high to excellent yields (up to 98%) with high enantioselectivities (up to 96%) and excellent diastereoselectiv...

recognizing of river flow pattern, deposition and erosion areas in meanders is highly important. despite the limitations of the physical models in laboratory investigation of flow pattern in meanders, mathematical models can be helpful. in this research, rsm and les turbulence models have been compared on sharp river bend of a laboratory flume using fluent software. the laboratory flume is a sh...

objective: diabetes is now known as one of the chronic diseases that besides body have negative effects on the psychological status of patients. the present study aimed to assess the physical and mental attributes of patients to evaluate and compare life expectancy and mental health among diabetic patients with normal ones. materials and methods: this was an analytic cross-sectional study, that...

Background It has been proved that physical activity has positive effects for all people. However, low activity is common among adolescents especially girl teenagers. The present study aimed to determine the condition of physical activity among girl adolescents by use of the stages of change derived from Trantheoretical model (TTM). Materials and Methods: This descriptive- analytical investiga...

An efficient chiral squaramide-catalysed enantioselective Michael addition of pyrazolin-5-ones to nitroalkenes has been developed. This reaction afforded the chiral pyrazol-3-ol derivatives in high to excellent yields (up to >99%) with high enantioselectivities (up to 94% ee) for most substrates under very low catalyst loading (0.25 mol%). This catalytic asymmetric reaction provides valuable an...

INTRODUCTION The first studies on the general circulation of water masses in the Mediterranean began in the early 1900s (Nielsen, 1912), depicting a circulation smooth and stable along the slopes. Major revisions arose only in the 1980s, after the satellite imagery revealed upwellings, meanders and eddies, that is the mesoscale dynamics (see for instance Millot, 1985, 1987a; Le Vourch et al., 1...

INTRODUCTION Adulthood male hypogonadism (HG) is the most common form of HG. Although testosterone (T) replacement therapy (TRT) is the most common way of treating HG, other options are available depending on patient's needs and expectations. AREAS COVERED We analyze alternative options to TRT as a medical intervention in treating HG. Gonadotropin (Gn) therapy is the treatment of choice in me...
