YLLINE'(theophylline ethylenediamine) is one of the most useful drugs employed in the management of bronchial asthma . Its therapeutic effects are closely related to its blood level.' This should approximate from 5 to 9 mcg/ml in serum. Segal et al in 1949 demonstrated that a rectal solution of 0 .5 gm of aminophylline in 15 cc water yielded a significant degree of protection against histamine ...

OBJECTIVE Disparities in sleep duration and efficiency between Black/African American (AA) and White/European American (EA) adults are well-documented. The objective of this study was to examine neighborhood disadvantage as an explanation for race differences in objectively measured sleep. METHODS Data were from 133 AA and 293 EA adults who participated in the sleep assessment protocol of the...

Both self-report and official crime data have known limitations, leading to the critical question as to whether inferences about the adolescent life-course of crime are different across these data sources. Using both official and self-report arrest data on a sample of subjects drawn from the Project on Human Development in Chicago Neighborhoods (PHDCN) longitudinal cohort study, this paper exam...

the scattered stories, due to the way they are put together in the shahnameh, show a thoughtful and systematic pattern and tell more than what they have in their appearance. according to the tradition of the shahnameh research, the book is divided into the following sections: mythical, heroic, and historical. although clear lines do not indicate this classification, the interval and overlapping...

Crystalline trypsinogen is most readily and completely transformed into trypsin by means of enterokinase in the range of pH 5.2-6.0 at 5 degrees C. and at a concentration of trypsinogen of not more than 0.1 mg. per ml. The action of enterokinase under these conditions is that of a typical enzyme. The process follows closely the course of a catalytic unimolecular reaction, the rate of formation ...

Recent interest in lithium-ion batteries for electric and hybrid vehicles, satellite, defense, and military applications has increased the demand on the computational efficiency of lithium-ion battery models. This paper presents an effective approach to simulate physics based lithium-ion battery models in real-time milliseconds for simulation and control in hybrid environments. The battery mode...

Although ecological researchers consistently find high rates of crime and violence within socioeconomically disadvantaged neighborhoods, there is little consensus as to why this pattern exists. To address this question, we use data from the National Longitudinal Study of Adolescent Health (n = 12,747) to examine three related research questions. Are neighborhood characteristics associated with ...

Ice clouds in the Earth's upper troposphere can form via homogeneous nucleation of ice in aqueous droplets. In this study we investigate the crystallisation, or lack of crystallisation, of the solute phase and ice in aqueous (NH(4))(3)H(SO(4))(2)/H(2)O and NH(4)HSO(4)/H(2)O droplets. This is done using in situ X-ray diffraction of emulsified solution droplets mounted on a cold stage. From the d...

2014 A theory is developed on the rotational relaxation time 03C4r of rigid rod-like molecules in concentrated solutions. The result is 03C4r oc c2 L9(03B1 cL2 d)-2 (In (L/d))-1 , where c is the concentration of rods, L and d are the rod length and diameter respectively and 03B1 is a certain numerical factor. This relaxation time is related to the static viscosity and is found to be in good agr...
