X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...

The present paper deals with design, construction and working of Accelerator and Brake operated by one pedal, which may be a technique for reducing road accidents. The main objective of this innovation is to eliminate the operator’s risk of pressing the wrong pedal at the time of emergency as well as reduction in the driver’s reaction time to switch from accelerator to brakes or vice versa. Thi...

INTRODUCTION This study focused on the value of quantitatively analyzed and qualitatively graded renal scintigraphy in relation to the expected duration of delayed graft function after kidney transplantation. A more reliable prediction of delayed graft function duration may result in a more tailored and patient-specific treatment regimen post-transplantation. METHODS From 2000 to 2014, patien...

BACKGROUND We aimed to investigate the immediate respiratory effects of cigar smoking(CS), among young smokers with and without mild asthma. MATERIALS AND METHODS Forty-seven young smokers (18-31years old, 29 males, average pack-years = 3.6 ± 2.8) were enrolled. Twenty-two were mild asthmatics(MA-subgroup) and the remaining 25 were otherwise healthy smokers(HS-subgroup). Exhaled carbon monoxi...

This study empirically investigated the effect of Cooperative teaching Method on Senior Secondary School Students’ Achievement and Retention in Financial Accounting Enugu State. Four research questions six hypotheses guided study. Pretest-posttest non-randomized control group design was adopted for The conducted Agbani Education zone population consisted all co-educational senior secondary scho...

PURPOSE High-sensitivity assays enabled the identification of C-reactive protein (hs-CRP) at levels that were previously undetectable. We aimed to determine if hs-CRP could reflect airway inflammation in children, by comparing hs-CRP with spirometry and impulse oscillometry (IOS) parameters and symptomatic severities. MATERIALS AND METHODS A total of 276 asthmatic children who visited Severan...

Climate extreme events have been observed more frequently since the 1970s throughout Ethiopia, which adversely affects socio-economic development of country, as its economy depends on agriculture, which, in turn, relies heavily annual and seasonal rainfall. extremes studies conducted Ethiopia are mainly limited to a specific location or watershed, making it difficult insights at national level....

BACKGROUND Impulse oscillometry (IOS) is a non-demanding lung function test. Its diagnostic use may be particularly useful in patients of advanced age with physical or mental limitations unable to perform spirometry. Only few reference equations are available for Caucasians, none of them covering the old age. Here, we provide reference equations up to advanced age and compare them with currentl...

INTRODUCTION Abnormality in distal lung function may occur in obesity due to reduction in resting lung volume; however, airway inflammation, vascular congestion and/or concomitant intrinsic airway disease may also be present. The goal of this study is to 1) describe the phenotype of lung function in obese subjects utilizing spirometry, plethysmography and oscillometry; and 2) evaluate residual ...

Impulse oscillometry (IOS) is a good method for measuring airway resistance. The aim of this study was to assess the diagnostic contribution of IOS combined with bronchial dilation test (BDT) when distinguishing between patients with asthma and those with chronic obstructive pulmonary disease (COPD). 870 were enrolled in the study including 561 patients with asthma, 100 patients with COPD and 2...
