Recycled engine oil was produced from used engine oil (15W-40) using a combination of MEK and 1-butanol solvents with an activated carbon adsorbent through the adsorption process. The experimental design matrix was prepared using Box-Behnken design (BBD) package within RSM, and recycled engine oil is optimized by response surface methodology (RSM). By varying solvent-to-oil ratio, the temperature and contact duration optimal conditions were identified as a 5.

Reports of ascariais causing complete bowel obstruction in adults are rare while having a high rate of morbidity and mortality. Here we present a case of a 35 years old female patient who presented with complete small bowel obstruction caused by >250 ascariasis worm.

We present what we believe to be the first report on rifampicin-resistant TB (RR-TB) detected using Xpert® MTB/RIF Ultra, comparably identified by rats sniffing sputum samples from presumptive TB patients: 88% of RR-TB detected using Ultra were identified by the rats. Further evaluation of the usefulness of rats for large-scale DR-TB contact triage testing is needed, especially in low- and middle-income countries, where resources are limited.
