Thermolysis of the heterometal LaFe complex precusor allowed the enhancement of crystal growth to create a LaFeO3 network structure.

Refill drinking water is a choice of drinking water, especially for the middle-income community due to the convenience and affordable price. Many studies in Indonesia reported that drinking water from drinking water refilling stations is less safe or contaminated by coliform. This study assessed the microbial and level of several heavy metals (Cadmium, chromium, and Lead) contamination on refill drinking water from drinking water refilling station in Bungus Teluk Kabung West Sumatera, Indonesia. It found that Cadmium, Chromium, and Lead were detected in all samples. Still, none of their levels exceed the maximum permissible limits based on the guideline value on Ministry of Health Republic of Indonesia number 492/MENKES/PER/IV/2010. Lead was found as the highest amount in sample B and then Chromium in sample A with values of 0.367 ppb and 0.143 ppb. The microbial contamination presence in all three refill drinking water samples with the total coliform was 28, 15, and 240 MPN per 100 ml for samples A, B, and C. Sample C has the highest microbial risk compare to A and B. The presence of E. Coli was also confirmed for all samples, and the metallic sheen identified it in all culture samples. Because the standard of the microbial parameter must be zero for coliform and E. Coli, these results revealed that all three refill drinking water samples from drinking water refilling stations Bungus Teluk Kabung are not eligible for direct consumption and could harm human health. The proper water treatment process or change in raw water sources need to be considered in the future. Inspection and monitoring from the health authority should be scheduled regularly to protect the consumers.

Introduction: Acute myocardial infarction is known with high mortality. The benefits of fibrinolytic administration in STEMI are time dependent. The purpose of this study is to evaluate the door-to-needle time for fibrinolytic therapy in STEMI patients.Methods: A cross sectional study of all patients who had STEMI was carried out to evaluate the management of STEMI. The duration from door-to-ECG time, door-to-needle time and the factors that contribute to the time frame in receiving treatment was reviewed. The outcomes and complications from fibrinolytic therapy were documented as well. The outcomes of the delayed in administering the treatment were also analyzed in the study.Result: Out of 19 patients received fibrinolytics within 30 minutes, 16 patients (84.2%) had good outcome. In 17 patients received fibrinolytics between 30 minutes to 1 hour, 6 patients (35.2%) had good outcome. In 15 patients received fibrinolytics more than 1 hour, 8 patients (53.3%) had good outcome.Conclusion: This study showed that a shorter door-to-needle time results in better outcome.Bangladesh Journal of Medical Science Vol.16(3) 2017 p.407-412

Simple synthesis of nanospherical TiO 2 by microwave hydrothermal method has been investigated. Titanium tetra isopropoxide (TTIP) and tetra methyl ammonium hydroxide (TMAOH) were used as precursor. The crystal phase and microstructure were characterized by X-Ray Diffraction (XRD) and transmission electron microscopy (TEM) including selected area diffraction (SAED). The presence of intense peak in the XRD patterns confirmed to anatase and in good agreement with SAED patterns. Nanospherical of particles were clearly seen in the TEM image and the size of particles was approximately 4-5 nm. Keywords :microwave hydrothermal, colloidal titanates, structure directing agent, nanospherical TiO 2 PENDAHULUANTitanium dioksida (TiO 2 ) telah banyak diteliti dalam beragam aplikasi karena memiliki sifat inert, stabil terhadap korosi yang disebabkan cahaya ataupun bahan kimia, relatif murah, dan tidak beracun [1,2]

Zinc gallium oxynitride, (Ga1-xZnx)(N1-xOx), was synthesized by the reaction of zinc gallium oxynitride, ZnGa2O4, with a solid nitrogen source of Li3N at 823 K. A thermolysis of the mixture of gallium salen and zinc acetate produced ZnGa2O4 particles with a 2D morphology. The optimization of zinc and gallium ratio was examined in synthesizing ZnGa2O4. After nitridation, zinc gallium oxynitride with a cauliflower-like morphology was produced as a major product for zinc-rich precursor, whereas LiGaO2 and GaN were the major products for zinc-poor precursor.
