Extraction of Nanocellulose for Eco-Friendly Biocomposite Adsorbent for Wastewater Treatment.

In the present study, nanocellulose was extracted from palm leaves to synthesize nanocellulose/chitosan nanocomposites for the removal of dyes from textile industrial wastewater. Nanocellulose is of interest in water purification technologies because of its high surface area and versatile surface chemistry. Following bleach, alkali, and acid treatments on palm leaves, nanocellulose is obtained as a white powder.

Fabrication and Characterization of Polypyrrole/Multi-Walled Carbon Nanotubes Thin Films Using Thermal Evaporation.

Polypyrrole/multiwalled carbon nanotubes composites (PPy/MWCNTs) were produced in an acidic solution utilizing an in situ oxidative polymerization method using ferric chloride as an oxidizing agent and sodium dodecyl sulfate as a soft template. Thermal evaporation was used to fabricate thin films from polypyrrole/multiwalled carbon nanotube composites. The resulting composites were examined by different techniques to explore their morphology, structural and electrical characteristics.

Theoretical Investigation of Vapor Transport Mechanism Using Tubular Membrane Distillation Module.

This paper's primary objective is to examine the vapor delivery mechanism through a tubular membrane distillation (MD) module. Experiments were conducted utilizing a hydrophobic tubular membrane module with a pore size of 0.2 µm.

Dysphagia aortica in a young patient with Behcet's Disease: Case report.

Dysphagia aortica is a rare aetiology of dysphagia resulting from an abnormality in thoracic aorta that causes extrinsic compression on the oesophagus. Dysphagia aortica includes aortic aneurysm, aortic dissection or even tortuous aorta and is seldom considered in the differential diagnosis of dysphagia. Herein, we report a 30-year-old man with Behcet's disease who presented with rapid progressive dysphagia and diagnosed as dysphagia aortica caused by saccular aortic aneurysm complicated by large para-aortic haematoma compressing the oesophagus.

Effective of metronidazole to bacterial flora in vagina and the impact of microbes on live birth rate during intracytoplasmic sperm injection (ICSI).

Purpose: The aim of this study was to investigate the impact of bacterial vaginal flora on life-birth rate during ICSI and influence of metronidazole as antibiotic treatment course before ICSI.

Method: We enrolled 71 women who were undergoing ICSI. At embryo transfer (ET), all of the women had quantitative vaginal culture, ET catheter-tip culture, and vaginal Gram stain scored for bacterial vaginosis.
