The combination of JC seed (0.9 g/L) as a flocculant reduced the dosage of SnCl4 as a coagulant from 11.1 g/L to 8.5 g/L with removals of 99.78%, 98.53% and 74.29% for SS, colour and COD, respectively. The presence of JC improved the sludge property with good morphology; the particles were in a rectangular shape, had clumps and strong agglomeration. These properties of sludge proved that JC seed could enhance the adsorption and bridging mechanism in the C-F procedure.This research was studied the optimum conditions for sulfate removal from lignite coal mine drainage in Thailand by ettringite precipitation using Central Composite Design. The effects of Ca/S and Al/S ratio (mole basis), reaction time and temperature on the sulfate removal efficiency were investigated. The statistical analysis showed that the Al/S ratio and reaction time had a significant effect on sulfate removal efficiency. The sulfate removal efficiency increases when Al/S ratio and reaction time are increased. The Ca/S ratio in the range of 1-7 was found to have no significant effect on sulfate removal efficiency. The optimal reaction time obtained from the predicted equation was 6.14 h, while the Ca/S and Al/S ratios were fixed at 4 and 4.5, respectively, at ambient temperature. Under the optimum conditions, sulfate removal of 99.6 and 99.0% was achieved in both Lamphun and Lampang mine drainage, respectively, which is very close to the predicted value (100%). This study showed that the sulfate removal efficiencies of Lamphun and Lampang mine drainage sharply increased from 33.3 to 89.9% and 42.3 to 81.8%, respectively, when the temperature was increased from 25 to 80 ○C during a 3 h reaction time. XRD results match well with a majority of ettringite and a minority of calcium carbonate when the precipitation was done at ambient temperature. this website However, monosulfate was found to be the majority when the precipitation was done at 80 ○C due to the decomposition of ettringite to monosulfate at the high temperature.The intravoxel incoherent motion (IVIM) model allows to map diffusion (D) and perfusion-related parameters (F and D*). Parameter estimation is, however, error-prone due to the non-linearity of the signal model, the limited signal-to-noise ratio (SNR) and the small volume fraction of perfusion in the in-vivo brain. In the present work, the performance of Bayesian inference was examined in the presence of brain pathologies characterized by hypo- and hyperperfusion. In particular, a hierarchical and a spatial prior were combined. Performance was compared relative to conventional segmented least squares regression, hierarchical prior only (non-segmented and segmented data likelihoods) and a deep learning approach. Realistic numerical brain IVIM simulations were conducted to assess errors relative to ground truth. In-vivo, data of 11 central nervous system cancer patients and 9 patients with acute stroke were acquired. The proposed method yielded reduced error in simulations for both the cancer and acute stroke scenarios compared to other methods across the whole investigated SNR range. The contrast-to-noise ratio of the proposed method was better or on par compared to the other techniques in-vivo. The proposed Bayesian approach hence improves IVIM parameter estimation in brain cancer and acute stroke.A new synthesized ternary polymer composite, polystyrene/polyacrylonitrile/polyindole (PSt/PAN/PIN), was used as an adsorbent. The structure of synthesized composite was supported by FTIR, BET, X-RD, TGA, SEM and AFM technique. A SPE method with synthesized composite was developed for the preconcentration of chromium, copper, iron, manganese, lead and zinc ions. The adsorption capacity were found in the range of 37.4-56.7 mg g-1. Under the best conditions, the preconcentration factor of method was found as 100. Relative standard deviation was found at ≤ 3.3% (n = 11). The detection limits of analytes were obtained as 0.9 μg L-1 for Cr(III), 1.2 μg L-1 for Cu(II), 2.0 μg L-1 for Fe(III), 1.4 μg L-1 for Mn(II), 0.9 μg L-1 for Pb(II) and 2.0 µg L-1 for Zn(II). Firstly, this SPE method was applied to certified reference material, and than coffee, tea, legumes. The trace metals was analyzed by flame atomic absorption spectrometry. Methamphetamine (METH) use causes significant vasoconstriction, which can be severe enough to cause bowel ischemia. Methamphetamines have also been shown to alter the immune response. These effects could predispose METH users to poor wound healing, increased infections, and other post-operative complications. We hypothesized that METH users would have longer length of stay and higher rates of complications compared to non-METH users. The trauma registry for our urban Level 1 trauma center was searched for patients that received an exploratory laparotomy from 2016 to 2019. A total 204 patients met criteria and 52 (25.5%) were METH positive. Length of stay (LOS), ventilator days, abbreviated injury scale (AIS), and wound class were compared using nonparametric statistics. Age and injury severity score (ISS) were compared using a Student's t-test. A Chi Square or Fisher's Exact test was used to compare sex, mechanism of injury, and rates of infectious complications. Methamphetamine-positive patients had a significantly higher rate of surgical site infections (7.4% versus 0%, P = 0.001). Patients that developed surgical site infection had equivalent rates of smoking and diabetes, as well as equivalent abdominal AIS and wound class compared to those who did not develop surgical site infection. Hospital and ICU LOS, ventilator days, ISS, and mortality were equivalent between METH positive and negative patients. Rates of other infectious complications were the same between groups. Methamphetamine use is associated with an increased rate of surgical site infection after trauma laparotomy. Other serious complications and mortality were not affected by METH use.Methamphetamine use is associated with an increased rate of surgical site infection after trauma laparotomy.
