Background and Objectives: Despite the increasing impact of heavy metal pollution in Persian Gulf due to urban growth and agricultural and petroleum activities, few studies have focused on the behavior and relationships of these pollutants in the biotic and abiotic components of aquatic environments. In this study, the amount of some metals (copper, iron, lead, cadmium, zinc and nickel) was det...

Larva Cossus cossus adalah serangga ordo Lepidoptera yang hidup di pohon menteng (Baccaurea racemosa) dari Desa Lejja Soppeng. dapat menghasilkan selulase untuk menghidrolisis selulosa menjadi gula sederhana (glukosa) dengan memutuskan ikatan 1,4-glikosidik dalam selulosa. Selulase tekstil digunakan industry detergen, makanan, dan kertas diproduksi oleh mikroba seperti selulolitik ragi. Tujuan ...

Virgin Coconut Oil (VCO) merupakan produk yang memiliki potensi dan manfaat baik untuk dikonsumsi. Namun dalam proses penyimpanannya dapat mengalami reaksi oksidasi hidrolisis mempengaruhi kualitas VCO menjadi buruk. Penelitian ini bertujuan mengetahui pengaruh penambahan minyak atsiri daun salam terhadap (VCO). Rancangan percobaan dipakai penelitian adalah rancangan acak lengkap dengan menggun...

Enam puluh juta ton amilum per tahun di Indonesia memiliki nilai jual yang rendah berdasarkan ekonomi skala internasional. Peningkatan pemanfaatan dapat dilakukan dengan menghidrolisis menjadi glukosa secara enzimatik oleh mikrob amilolitik. Yeast amilolitik pertumbuhan lebih cepat, efektif memecah dari kapang dan digunakan sebagai protein sel tunggal. Penelitian ini bertujuan untuk mendapatkan...

mangrove sediments were collected during wet and dry seasons from nine stations in khamir,laft and natural reservoir mangrove-dense areas of hormozgan province in the south of iran. σ pcbs ranged from 5.33 to 15.5 ng/g dry weight and the dominant congener was no.153. average σ ddts for khamir and laft mangroves were 16.58 ± 1.51 and 18.8 ± 9.98 ng/g dry weight. ddt was more abundant than dde an...

background: tissue expanders are devices which are used to create enough skin to form suitable flap in restoration of great skin deficiencies which are not modified initially. the current study aimed at investigating the patients’ satisfaction and the complications such as rupture, hematoma, wound infection, seroma, leakage, chronic pain, and expander expose of internal (implanted under the ski...

this research uses computational modeling to explore another method to increase diesel engine performance while maintaining low pollutant emission levels. previous studies have shown that injection-rate profiles and injector configurations play important roles on the performance and emissions of particulate and nox in di diesel engines. since the most important engine design parameters, includi...
