Aerosols can influence the climate indirectly by acting as cloud condensation nuclei and/or ice nuclei, thereby modifying cloud optical properties. In contrast to the widespread global warming, the central and south central United States display a noteworthy overall cooling trend during the 20(th) century, with an especially striking cooling trend in summertime daily maximum temperature (Tmax) ...

Objective To investigate the impact of urethral catheterization on uroflow by comparing urodynamic parameters of free uroflowmetry versus pressure-flow study in adult patients with benign prostatic hyperplasia, female stress incontinence, lumbosacral spinal injury or spina bifida. Methods Each patient was required to perform pressure-flow study immediately following free uroflowmetry. Maximum f...

This work examines the existence of efficient polynomial-time approximation schemes (EPTAS) for a variety of problems contained in the syntactic classes Planar TMIN, Planar TMAX, and Planar MPSAT as defined by Khanna and Motwani. Based on the recent work of Alber, Bodlaender, Fernau and Niedermeier and others, we describe subclasses of problems from Planar TMIN, Planar TMAX, and Planar MPSAT th...

As a means of assessing ventricular performance, we analyzed the time-varying ratio of instantaneous pressure, P(t) , to instantaneous volume, V(t), in the canine left ventricle. Intraventricular volume was measured by plethysmography, while the right heart was totally bypassed. The cardiac nerves were sectioned, and an epinephrine infusion was used to alter the contractile state. The instantan...

BACKGROUND The absorption of levothyroxine (LT4) is affected by many factors. Bariatric surgery is recommended in severely obese patients. The aim of this study was to determine the consequences of bariatric surgery on LT4 pharmacokinetic parameters, and to identify the regions of the gastrointestinal tract where LT4 is absorbed in patients with severe obesity before and after surgery. METHOD...

The experimental technique offered by temperature-modulated differential scanning calorimeter (TMDSC) used to investigate the thermal relaxation dynamics through the glass transition as a function of frequency was studied for pure PMMA and PMMA-single wall carbon nanotubes (SWCNTs) composites. A strong dependence of the temperature dependence peak in the imaginary part of complex heat capacity ...

OBJECTIVES The aim of this study is to compare the glycaemic and insulinemic response of type 2 diabetic patients after oral administration of 250 ml of two enteral formulas: a specific formula (Novasource Diabet Smartflex) against a standard isocaloric formula. METHODS The design was a cross-over study, with the diabetic patients (n = 15) receiving one of the two formulas in random order. Gl...

Sulphadimidine is used in the treatment of susceptible enteric bacteria that could cause enteritis and since piroxicam is a potent anti-inflammatory agent, it is co-administered with piroxicam intramuscularly. In view of this, effects of piroxicam on the pharmacokinetics of sulphadimidine were studied in West African Dwarf (WAD) goats. Twenty goats of both sexes, aged 1-year-old and weighing 10...

Over the last century the Northern Hemisphere has experienced rapid climate warming, but this warming has not been evenly distributed seasonally, as well as diurnally. The implications of such seasonal and diurnal heterogeneous warming on regional and global vegetation photosynthetic activity, however, are still poorly understood. Here, we investigated for different seasons how photosynthetic a...

Regional reconstructions of air temperature over the past millennium provide critical context for ongoing climate change, but they are temporally limited in recent period or absent many parts world. We demonstrate use latewood blue intensity (LWB) to reconstruct current-year growing (warm) season maximum temperatures (Tmax) low-to-mid latitudes (30°-50°N) western North America. present a new tr...
