The aim of this study was to degrade furfural by a new nanotube system. To degrade some organic pollutants as well as to reduce the amount of furfural which is a well-known pollutant in oil industry, the photocatalytic process along with ultraviolet (UV) irradiation may be employed. In this study, the UV/TiO2/Pd system in which the nanoparticles of palladium doped into the titanium dioxide was ...

The appropriate temperature and growth supplementary factors such as fetal bovine serum (FBS) are the necessities needed for cell growth in culture medium. In this regards, the effect of Leibovitz-15 (L-15) medium containing different concentrations of fetal bovine serum (FBS) was assessed on growth and proliferation of cultivated liver cells of klunzingerchr('39')s mullet, Liza klunzingeri, in...

A photovoltaic-thermal (PV-T) hybrid collector evaporator was designed and developed to produce electrical energy extract thermal simultaneously from the panel using refrigerant circulated tubes. The absorbs heat photovoltaic panels during its phase change liquid vapour. PV-T evaporators deliver both electricity outputs. An R-32 refrigerant-based solar-assisted pump water heating system with a ...

The application of the expanded granular sludge bed (EGSB) reactor for the anaerobic treatment of low-strength soluble wastewaters using ethanol as a model substrate was investigated in laboratory-scale reactors at 30oC. Chemical oxygen demand (COD) removal efficiency was above 80% at organic loading rates up to12 g COD/L . d with influent concentrations as low as 100 to 200 mg COD/L. These res...

Tujuan penelitian adalah untuk mengetahui jenis-jenis udang yang ditemukan perairan Desa Menco. Pengambilan sampel dilakukan pada tiga titik selama 3 Minggu, dengan menggunakan alat tangkap wangkong (trap net). Sampel diperoleh diidentifikasi dian...

Xylanases are hydrolytic enzymes with wide range of applications in food processing, bleaching pulp paper manufacturing industry, bio-conversion biomass wastes to fermentable sugars and enhancing nutrient digestibility animal feeds. The optimization growth conditions evaluation an appropriate substrate as carbon source among cassava peels, corn cobs, wheat bran rice husk on xylanase production ...

low temperature is one of main factors limiting distribution of woody plants. in order to evaluate the resistance of 4-years old seedlings and adult trees of maclura pomifera to freezing stress, a factorial experiment was carried out based on completely randomized design with three replications in the faculty of agriculture, university of tehran. during 2012-2013 sampling were done from the ann...

Aspergillus flavus (A. flavus) producing aflatoxin frequently contaminates crops such as soybeans. The growth of this mold on soybeans and other foodstuffs is affected by temperature and relative humidity (RH). The aim of this study was to measure the growth of A. flavus BIO 2237 and aflatoxin production at different temperatures and RH. Aspergillus flavus BIO 2237 was isolated from Indonesia o...

N atto is a traditional Japanese food made by boiling or steaming soybeans and fermenting them with the Bacillus subtilis natto. The bacillus bacteria activate a fermenting process that lends the beans their notoriously sour aroma, nutty flavor, and slippery texture. The Bacillus subtilis natto is a rod-shaped bacterium with a relatively high heat tolerance. Compared to other bacteria that have...
