A novel fluidized bed bioreactor (FBBR) was designed by integration of anaerobic granular activated carbon and aerobic sponge reactors. This FBBR was evaluated at different sponge volume fractions for treating a synthetic wastewater. Polyester urethane sponge with cube size of 1 × 1 × 1 cm and density of 28-30 kg/m(3) with 90 cells per 25 mm was used as biomass carrier. The results indicate tha...

The cell adhesion in a multiwalled carbon nanotube-coated collagen sponge (MWCNT-coated sponge) was investigated. Immediately after seeding, the cells adhered to the inner surface of the MWCNT-coated sponge and a significantly larger number of cells were observed there than for a pure collagen sponge used as control. On the MWCNT-coated sponge, the cells appeared favorable adhesion and spread i...

Background Anastomotic leakage is a feared complication following colorectal surgery and is associated with early and long-term morbidity and mortality. The presacral cavity as the result of anastomotic leakage can be treated with an endo-sponge (B-Braun Medical). The aim was to assess the effectiveness of endo-sponge treatment of the presacral cavity as result of anastomotic leakage in the Net...

This experiment was conducted to determine the reproductive performance of Arabian ewes treated with short and long-term progesterone devices in addition to low doses of equine chorionic gonadotropin (eCG) during the anoestrus season. A total of 36 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; (MAP)) were applied and removed after 6 days; i...

Abundant steeply-dipping thick coal seams (SDTCS) have been found in Xinjiang, China, and they are mined largely by the horizontal section top-coal caving (HSTCC) method. The hanging wall of the HSTCC face is nearly vertical and does not fracture easily after the underlying coal is extracted. As a result, stress tends to concentrate in the hanging wall of the lower-section working face (LSWF) a...

Background: Suicide is one of the leading factors of death worldwide. Hanging is one of the most common methods of suicide. This study was designed to evaluate post mortem toxicology laboratory findings of subjects with hanging death in northeast Iran.  Methods: This study was carried out on reported cases with hanging death to Razavi Khorasan Province-General Office of Iranian Legal Medicine O...

As the increase threat of flood risk and environmental safety due to the urbanization, Sponge city research has been attracting extensive attention both in practical and theoretical research field. To date, there are only scattered studies about Sponge city. Moreover, vary names of Sponge city prevalent in different countries, which leads to disconnection of literature in the same field of Spon...

Most studies of sedentary behavior have focused on television use or screen time. This study aims to examine adolescent girls' participation in a variety of recreational sedentary behaviors (e.g., talking on the phone and hanging around), and their association with physical activity (PA), dietary behaviors, and body mass index. Data were from a sample of 283 adolescent girls. Recreational seden...

A pigment-producing strain of Serratia rubidaea was isolated from two consecutive cultures from a sponge of silastic foam used as a dressing for chronic crural ulcers. The bacterium caused a red discolouration of the sponge and the surrounding part of the leg. The silastic sponge creates a new type of environment for microorganisms. The growth of previously rare bacteria such as S. rubidaea may...
