Background and objectives: One of the most important components of rangeland ecosystems is soil that their degradation will reduce rangeland production capacity. About half of the world's lands are rangelands and they contain more than one-third of the biosphere carbon pool. Therefore, these lands have a high potential for carbon sequestration. This study was conducted to investigate the soil c...
1. The amount of lean tissue in the body can be assessed by measuring total body nitrogen, total body potassium or fat-free mass. To compare these techniques we have measured total body nitrogen, total body potassium and fat-free mass in 91 healthy subjects (62 males, 29 females). 2. Total body nitrogen in the women and civilian men agreed closely with the few values reported previously and was...

OBJECTIVE To evaluate the performance of total PSA (tPSA), the free/total PSA ratio (f/tPSA), complexed PSA (cPSA) and the complexed/total PSA ratio (c/tPSA) in prostate cancer detection. METHODS Frozen sera of 442 patients have been analysed for tPSA, free PSA (fPSA) and cPSA. 131 patients had prostate cancer and 311 patients benign prostatic hyperplasia. RESULTS Differences in the distrib...
Danau Sebedang merupakan danau alami yang terletak di Kecamatan Sebawi Kabupaten Sambas. Fungsi utama yaitu sebagai sumber air baku pengolahan bersih dan objek wisata. Adanya proses alam aktivitas antropogenik disekitar dapat menyumbang masukan berupa bahan organik anorganik ke ekosistem danau. Salah satu dampak mungkin terjadi adalah terjadinya pengayaan nutrien pada perairan Penelitian ini be...
A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea. When both types of diets were fed, nitrogen balance and utilization tended to increase by cecal ligation while total nitrogen excretion tended to decrease. Colostom...
