Methane is a potential source of carbon in drinking water. Typically, it removed at waterworks during an initial treatment step such as aeration or stripping. Remaining methane may be converted by methane-oxidizing bacteria to organic carbon, which then available for heterotrophic growth and ultimately contribute invertebrate growth. We investigated the presence invertebrates with incomplete re...

~Ihe nature of Langerhans cells is disputed. ~fhey have been considered effete melanocytes (1, 2), postmelanin-synthetic cells (3), melanocyte precursors (4), intraepidermal nerve endings (5, 6), or postdivisional stages of previously melanogenic melanocytes (7). Under the electron microscope, melanocytes and Langerhans cells are distinguished by highly characteristic cytoplasmic or-ganelles: m...

Disinfection by-products (DBPs) are regulated in drinking water in a number of countries. This critical review focuses on the issues associated with DBP regulatory compliance, including methods for DBP analysis, occurrence levels, the regulation comparison among various countries, DBP compliance strategies, and emerging DBPs. The regulation comparison between China and the United States (US) in...

While the annual European demand for polyolefins is 25 million tonnes, only 3 tonnes of recycled find their place in market, despite collecting 15 post-consumer every year. Brand owners care products are showing interest using plastics packaging. However, there a general concern these materials, as polymers can contain unwanted substances that may expose consumer to health risks or make packagi...

BACKGROUND Laparoscopic surgery has become the gold-standard treatment for ovarian endometriomas. The objective of this trial was to evaluate different procedures for the laparoscopic excision of ovarian endometriomas with the stripping technique. METHODS Forty-eight patients with ovarian endometrioma were enrolled in two consecutive independent randomized trials. Two different techniques wer...

INTRODUCTION Patients with esophageal cancer frequently cannot tolerate thoracotomy due to their overall debilitated condition. Moreover, some patients have severe adhesions in the thoracic cavity. Eversion stripping of the esophagus is an option for resection in these patients. PRESENTATION OF CASE A 64-year-old man was admitted to our institution with the chief complaint of epigastric pain....

Ammonia (NH3) emissions deriving from the management of livestock manure have a significant environmental impact, and therefore it is important to reduce them. Among available options, process NH3 stripping promising remove manures digestates recovering as mineral fertilizer (e.g., ammonium sulfate) that more widely adoptable on farms. The traditional takes place in batches; however, this study...

We investigate environmental effects on evolution of cluster galaxies under hierarchical structure formation scenario using combination of a dissipationless N-body simulation and a semi-analytic model of galaxy formation. The N-body simulation enables us to calculate orbits of galaxies in simulated clusters. Therefore we can include stripping of cold gas from the galactic disks by ram pressure ...

This study analyzed the influence of different ammonia stripping parameters on removal efficiency and mass transfer rate. Ammonia was performed two devices, a column packed tower, with artificial ammonium hydroxide wastewater. First, concentration pH were varied in without liquid circulation. At same pH, rate constant, irrespective initial concentration. When increased, fraction also resulting ...
