Exposure to hydrogen sulphide and respiratory function.
A study was carried out to assess possible effects of low concentrations of hydrogen sulphide on respiratory function. The cohort comprised 26 male pulp mill workers (mean age 40.3, range 22-60 years) with a daily exposure to hydrogen sulphide in the workplace, and 10 volunteers, who had asthma (three men, mean age 40.7, range 33 to 50 years, and seven women, mean age 44.1, range 31 to 61 years...
متن کاملPreparation of Sugarcane Bagasse Modified with the Thiophosphoryl Function and Its Capacity for Cadmium Adsorption
Sugarcane bagasse (SCB) is an important by-product from the sucroalcohol industry in Brazil, and it is a convenient raw material for new applications. In this study, SCB was modified with thiophosphoryl chloride in order to attach the P=S chelating moiety to the fibers, aiming at the production of a new material (SCB-F) with increased cadmium adsorption capacity. The SCB-F was characterized by ...
متن کاملModified Isochronous Coordination Function for Enhancement of VoIP Call Capacity over IEEE 802.11 WLAN
VoIP over IEEE 802.11 wireless local area network (WLAN) is growing very fast and is providing a cost effective alternative for voice communications. WLANs were initially set up to handle bursty nonreal time type of data traffic. Therefore, the wireless access protocols initially defined are not suitable for voice traffic. Subsequently, updates in the standard have been made to provision for Qo...
متن کاملLung function and aerobic capacity in adult patients following modified Fontan procedure.
OBJECTIVE To examine cardiopulmonary performance in 52 adult patients with a Fontan circulation. DESIGN Retrospective cohort study. Values of maximum oxygen uptake (VO(2)max), maximum heart rate (HRmax), forced vital capacity (FVC), and forced expiratory volume in one second (FEV(1)) were compared with predictive values for different age groups. Patients were further subdivided into those wit...
متن کاملTwo-dimensional layered transition metal disulphides for effective encapsulation of high-capacity lithium sulphide cathodes.
Fully lithiated lithium sulphide (Li2S) is currently being explored as a promising cathode material for emerging energy storage applications. Like their sulphur counterparts, Li2S cathodes require effective encapsulation to reduce the dissolution of intermediate lithium polysulphide (Li2Sn, n=4-8) species into the electrolyte. Here we report, the encapsulation of Li2S cathodes using two-dimensi...
