BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major public health concern, accounting for 3 million deaths annually, 90% of which occur in low- and middle-income countries. Pulmonary tuberculosis (PTB) as a contributory factor in the aetiology of COPD is under debate, with most epidemiologic evidence suggesting a positive association. OBJECTIVES To compile a systematic review o...

Animal wastes are a major contributor of nutrients and enteric microorganisms to surface water and ground water. Polyacrylamide (PAM) mixtures are an effective flocculent, and we hypothesized that they would reduce transport of microorganisms in flowing water. After waste water running at 60.0 1 min(-1) flowed over PAM + Al2(SO4)3, or PAM + CaO in furrows, total coliform bacteria (TC) and fecal...

Using a transient hot-wire method, the thermal conductivity of the CaO–SiO2–B2O3 mold flux system was measured. The effects of temperature, BO1.5 concentration and basicity on the thermal conductivity were considered, along with structural investigation by Raman spectroscopy. It was found that the addition of boron oxide caused both a decrement and increment of thermal conductivity, depending o...

OBJECTIVE To assess the sensitivity and specificity of flow-volume curves in detecting central airway obstruction (CAO), and to determine whether their quantitative and qualitative criteria are associated with the location, type and degree of obstruction. METHODS Over a four-month period, we consecutively evaluated patients with bronchoscopy indicated. Over a one-week period, all patients und...

This work assesses the effect of adding CaO during pyrolysis waste tires (WT) using a twin-auger reactor on properties derived products. Pyrolysis was conducted in lab-scale facility at temperature 475 °C, solid residence time 3.5 min, WT mass flow rate 1.16 kg/h, and N2 300 mL/min. continuously fed ratios 10, 15, 20 wt %, according to rate, two particle size ranges: fine (105–149 μm) coarse (1...

A problem arises in cases of CAO in patients who have not been active smokers. In these cases, following the definition of COPD, other factors such as passive smoking or exposure to other inhaled irritants play a major role. Indeed, a number of previous studies have established passive smoking or biomass exposure as causes of CAO and therefore COPD [7, 8] . In those cases when the patient has n...

This study was carried out to identify the conditions of formation of calcium sulphoaluminate (3CaO·3Al(2)O(3)·CaSO(4)) by the sintering of a limestone (CaCO(3)) and alunite [K(2)SO(4)·Al(2)(SO(4))(3)·4Al(OH)(3)] mixture with the following reagents: K(2)SO(4), CaCO(3), Al(OH)(3), CaSO(4)·2H(2)O, and SiO(2). When K(2)SO(4), CaCO(3), Al(OH)(3), CaSO(4)·2H(2)O were mixed in molar ratios of 1:3:6:3...

Differential heating curves were used to study the behavior of calcium sulfate at high temperatures. After cooling, the material was examined by means of the petrographic microscope and by study of its X-ray pattern. It was found that the beta-to-alpha transition of calcium sulfate occurs at approximately 1,214° C, and the conclusion of i ts discoverer that the high temperature form is unstable...
