Objectives: Various instruments and methods evaluate addiction to the Internet, mobile, and smartphone use. Subject-reported outcome measures, such as the smartphone addiction scale (SAS) assess such addiction. The objectives of this study were to cross-culturally adapt the SAS into Persian (SAS-Pr) and to evaluate the properties of reliability and validity in the Persian setting. Methods: The...

the objectives of this study were to evaluate the effects of nitrogen fertigation frequency on lint yield, lint properties, chlorophyll content (spad readings), and the photosynthesis rate (pr) of cotton. this study was carried out in the southeastern anatolia region of turkey in 2011 and 2012 with drip-irrigated cotton. the maximum lint yield (1,856 kg ha-1) was obtained with one lateral for e...

A number of analogues of the Mitsui Chemicals ethylene trimerisation system (IV) have been explored, in which one of the donor atoms have been modified. Thus, a series of mono-anionic tridentate phenoxy-imine (3-(t-butyl)-2-(OH)-C6H4C=N(C(CH3)2CH2OMe) 1, 3-(adamantyl)-2-(OH)-C6H4C=N(2'-(2''-(SMe)C6H4)-C6H4) 2, 3-(t-butyl)-2-(OSiMe3)-C6H4C=N(C(CH3)2CH2OMe) 3) or phenoxy-amine (3,5-di(t-butyl)-2-...

Blackwell games are infinite games of imperfect information. The two players simultaneously make their moves and are then informed of each other’s moves. Payoff is determined by a Borel measurable function f on the set of possible resulting sequences of moves. A standard result in Game Theory is that finite games of this type are determined. Blackwell proved that infinite games are determined, ...

N-Terminal self-cleavage (autoprocessing) of the HIV-1 protease precursor is crucial for liberating the active dimer. Under drug pressure, evolving mutations are predicted to modulate autoprocessing, and the reduced catalytic activity of the mature protease (PR) is likely compensated by enhanced conformational/dimer stability and reduced susceptibility to self-degradation (autoproteolysis). One...

Human immunodeficiency virus type 1 protease (HIV-1 PR) and renin are primary targets toward AIDS and hypertension therapies, respectively. Molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) free-energy calculations and inhibition assays for canagliflozin, an antidiabetic agent verified its effective binding to both proteins (ΔG(pred) = -9.1 kcal mol(-1) for canagliflozin-renin; K(i,e...

PURPOSE The aim of this study was to investigate the effect of self-paced active recovery (AR) and passive recovery (PR) on blood lactate removal following a 200 m freestyle swimming trial. PATIENTS AND METHODS Fourteen young swimmers (with a training frequency of 6-8 sessions per week) performed two maximal 200 m freestyle trials followed by 15 minutes of different recovery methods, on separ...

Can a computer which runs for time ω 2 compute more than one which runs for time ω? No. Not, at least, for the infinite computer we describe. Our computer gets more powerful when the set of its steps gets larger. We prove that they theory of second order arithmetic cannot be decided by computers running to countable time. Our motivation is to build a computer that will store and manipulate surr...

THIS APPENDIX PROVIDES a simple model of basis risk based on Clarke (2011) and uses it to argue that our 2011 insurance experiment can be used to test whether migration is risky and migrants are risk averse.1 There are two payoff-relevant states {L H} which lead to income at the destination yL ≤ yH . We assume pr(H) = πy . There are two rainfall states {RL RH} and rainfall insurance makes a pay...
