background: in this study, ferrate (vi) and ultraviolet (uv) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (cod). although ferrate (vi) and uv have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of simultaneous...

The objectives of this experiment were to determine if treatment of beef heifers with progesterone (P4) using an intravaginal device alone or in combination with estradiol benzoate (EB) would induce estrus and cause development of corpora lutea (CL) with a typical life span. Peripubertal heifers (n = 311) were used when about 40% of the heifers had a functional CL. The heifers were assigned to ...

A relatively simple, sensitive, selective, automatic fluorimetric method for the simultaneous determination of chromium(III) and chromium(VI) by flow injection analysis (FIA) was developed. The method is based on the selective oxidation of the non-fluorescing reagent 2-(a-pyridyl)thioquinaldinamide (PTQA), which with Cr yields an intensely fluorescent product (lex = 360 nm; lem = 500 nm). Chrom...

the ground improvement using plastic board drain (pbd) in soft soil was undertaken by sand mat formation, pbd installation, preloading surcharge, and removal of surcharge. during this procedure, the sand mat formation induced an initial settlement. however, it was very difficult to estimate that settlement due to pbd installation, which frequently destroyed the instruments installed in the grou...

behaviors of simultaneous removal of no and so2 using the coculture of anaerobic denitrifying bacteria and sulfate reducing bacteria were investigated in a bench-scale biotrickling-filter. approximate 20 days were required to use the landfill leachate as the microbial seed to develop the biofilm on the surface of packing material. when the combined no/so2 removal biotrickling-filter was operate...

background this study demonstrates the removal efficiency of phenol from aqueous solutions by electrocoagulation process using aluminum electrodes and also investigates solution chemistry and polymeric natural organic matters on removal efficiency objectives: the main aim of this work was to focus on the removal of phenol by electrocoagulation process using aluminum electrodes. materials and me...

Patients requiring tracheostomies tend to have a longer length of stay due to their underlying disease. After a thorough literature search, Garrubba and colleagues found only three studies assessing the impact of multidisciplinary teams (MDTs) on tracheostomy patients on the ward. One consistent observation was the decreased time to decannulation after institution of MDT care when compared with...

AIMS The approach to infected cardiac devices has changed during recent decades. Optimal treatment is still a matter of debate, especially in pacemaker-dependent patients. Therefore, we investigated the management and outcome of patients with pacemaker infections in a single centre over four decades. METHODS AND RESULTS We conducted a retrospective analysis of 4212 patients and extracted thos...

INTRODUCTION This study was performed to observe the efficacy of a modified surgical wound dressing applied as part of decannulation wound care after tracheotomy. METHODS Eighty-four patients were randomly allocated into a traditional care group, a surgical wound dressing group, and a modified surgical wound dressing group. Each group comprised 28 patients. The following outcomes were observe...
