this work concerns the peristaltic flow of a williamson fluid model in an inclined asymmetric channel under combined effects of heat and mass transfer. the governing nonlinear partial differential equations are simplified under the lubrication approach and then solved analytically and numerically. the analytical results are computed with the help of regular perturbation and the numerical result...

we derive the formulas of the maximal andminimal ranks of four real matrices $x_{1},x_{2},x_{3}$ and $x_{4}$in common solution $x=x_{1}+x_{2}i+x_{3}j+x_{4}k$ to quaternionmatrix equations $a_{1}x=c_{1},xb_{2}=c_{2},a_{3}xb_{3}=c_{3}$. asapplications, we establish necessary and sufficient conditions forthe existence of the common real and complex solutions to the matrixequations. we give the exp...

Aim: To asses the incidence of PDPH in different gauges of spinal needle in relation to age. Methods: This Comparative Study was carried out at AFIU (RWP), Railway General Hospital Rawalpindi and Children Complex Multan from August 2007 to August 2008. A total of 1500 patients were studied in 9 different groups (A1, B1, C1, A2, B2, C2, A3, B3, C3) with group A,B and C for 23G, 25G and 27G respe...

We studied the early and late effects of hypertonic resuscitation (HR) on the injured brain using a porcine model of hemorrhagic shock and focal cryogenic brain injury. After shock, swine were randomly assigned to receive a bolus (4 cc/kg) of either Ringers lactate (RL) or 7.5% hypertonic saline in 6% Dextran 70, followed by either RL or hypertonic sodium lactate to restore mean arterial pressu...

AIM The aim of this study is to compare the effect of lactated ringer (LR), vasopressin (Vaso) or terlipressin (Terli) on uncontrolled hemorrhagic shock (UHS) in rats. METHODS 48 rats were divided into four treatment groups for UHS study. Vaso group was given bolus vasopressin (0.8 U/kg); the Terli group was given bolus terlipressin (15 mcg/kg); LR group was given LR and the sham group was no...

The influence of cold (4°C)used to prepare cells for metabolic investigations was examined with Trichomonas gallinae in this study. Cells washed withcold diluent in a refrigerated centrifuge were found to be less stimulated in their gas production at 37°C when exposed to glucose ormaltose than cells washed at room temperature conditions. Such cold-prepared cells had higher initial glycogen cont...

BACKGROUND AND OBJECTIVES Increased intravenous (IV) hydration is associated with decreased labor duration and oxytocin augmentation in nulliparous women when oral fluid is restricted. The objective of this study was to determine the effect of increased IV hydration on the duration of labor when access to oral fluid was unrestricted. METHODS Term, nulliparous women with uncomplicated singleto...

Wing morphology strongly affects flight performance which may consequently decline during feather moult due to the creation of feather gaps in the wing. Hence, the size and shape of moult-related wing gap may directly affect flight capacity. Here I examined the rare divergent primary moult sequence compared to the more common descendant moult sequence. In the divergent moult, the focus of prima...

BACKGROUND Vasoconstriction, an inherent property of Hemoglobin Based Oxygen Carriers (HBOC) potentially due to nitric oxide (NO) scavenging, may increase cardiovascular complications in HBOC resuscitated trauma patients. The purpose of this study was to determine if co-administration of a weak NO donor, intravenous nitroglycerin (NTG), with HBOC-201 during resuscitation from hemorrhagic shock ...
