While bar-headed geese are renowned for migration at high altitude over the Himalayas, previous work on captive birds suggested that these geese are unable to maintain rates of oxygen consumption while running in severely hypoxic conditions. To investigate this paradox, we re-examined the running performance and heart rates of bar-headed geese and barnacle geese (a low altitude species) during ...

An aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. In this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial TFC (thin film composite) polyamide nanofilter. The effects of pH (6.5-8.5), pressure (4-10 bar), concentration of to...

OBJECTIVE To assess the print media coverage of California's smokefree bar law in the state of California. DESIGN Content analysis of newspaper, trade journal, and magazine items. SUBJECTS Items regarding the smokefree bar law published seven months before and one year following the implementation of the smokefree bar law (June 1997 to December 1998). Items consisted of news articles (n = 4...

Air terproduksi dari industri minyak dan gas memerlukan pengolahan untuk menurunkan parameter pencemarnya sebelum dibuang ke lingkungan atau digunakan kembali. Proses filtrasi dengan membran sebagai salah satu pilihan paling handal proses air limbah dapat mengalami masalah fouling yang mengurangi efisiensinya. Penelitian ini bertujuan menganalisis model pembentukan pada Reverse Osmosis (RO) men...

In the standard scenario of isolated low-mass star formation, strongly magnetized molecular clouds are envisioned to condense gradually into dense cores, driven by ambipolar diffusion. Once the cores become magnetically supercritical, they collapse to form stars. Previous studies based on this scenario are limited to axisymmetric calculations leading to single supercritical core formation. The ...

Much has been written recently about the potential hazards versus benefits of antibacterial (biocide)– containing soaps. The aim of this study was to evaluate the Bar soap from 20 different Dental clinics for microbial contamination, while it was “in-use”. This prospective study was performed with 40 samples between November and December 2015, at Dental clinic at Vellore in Tamilnadu, India. Of...

Bar-headed geese fly at altitudes of up to 9,000 m on their biannual migration over the Himalayas. To determine whether the flight muscle of this species has evolved to facilitate exercise at high altitude, we compared the respiratory properties of permeabilized muscle fibers from bar-headed geese and several low-altitude waterfowl species. Respiratory capacities were assessed for maximal ADP s...
