This study investigates the use of bottom ash as an adsorbent with and without chemical activation treatment. also determines effect pH stirring speed on efficiency in adsorption color COD. Bottom was ground sieved by 100 mesh sieves activated hydrochloric acid 2%. The experiments were conducted at variations 6, 8, 10; contact time 30, 60, 90 minutes; speeds 30 60 rpm. most effective non-activa...

OBJECTIVE To evaluate clinicobiochemical factors predicting severe hepatic fibrosis in patients with chronic hepatitis C virus (HCV) infection. SETTING Tertiary institution. PARTICIPANTS 859 treatment-naïve Korean patients with HCV who underwent liver biopsy. Severe fibrosis was defined as fibrosis stage ≥3 based on the METAVIR system. PRIMARY OUTCOME MEASURES Clinicobiochemical factors p...

We study the possible singularities of isotropic cosmological models that have a varying speed of light as well as a varying gravitational constant. The field equations typically reduce to two dimensional systems which are then analyzed both by dynamical systems techniques in phase space and by applying the method of asymptotic splittings. In the general case we find initially expanding closed ...

The study assessed CNC routing quality on maple and oak samples, using 90º V-Grooving router bits at various milling angles as function of grain orientation: 0°, 15°, 30°, 45°, 60°, 75°, 90°, feed speeds 3 6 m/min spindle speed 15,000 rpm. was evaluated by roughness parameters for the V flank surfaces visual examination flanks’ edges. change in had no significant effect flanks surface both spec...

this study aimed to compare the effects of high intensity and high volume training on lactate accumulation, time performance and vo2peak in 10-14 years old distance runners. 20 male endurance runners aged 12.5±2.32 years old and with a height of 154.62±3.27 cm, weight of 34.5±5.12 kg, maximum heart rate of 207.5±3.1 and vo2max of 36.45±3.22 ml /kg/min took part in the experiment. the experiment...

The effect of an alteration from regular endurance to interval (10-20-30) training on the health profile, muscular adaptations, maximum oxygen uptake (Vo(2max)), and performance of runners was examined. Eighteen moderately trained individuals (6 females and 12 males; Vo(2max): 52.2 ± 1.5 ml·kg(-1)·min(-1)) (means ± SE) were divided into a high-intensity training (10-20-30; 3 women and 7 men) an...

Increased levels of albuminuria and proteinuria, both linked to augmented renin-angiotensin system (RAS) activity, are associated with adverse kidney and cardiovascular events. However, the relationship between variations in urinary albumin excretion (UAE) and total protein excretion (UTPE) in the normal range and RAS activity is unclear. We examined the association between UAE and UTPE and the...
