aerobic digestion was useful for mixed sludge of west ahwaz sewage treatment plant. results showed that after 12 days 38% of tvs reduced. this meets the environmental standards. after 19 days detention time in the bioreactor, cod, vss, tvs, tss, ts, were 40 ,56, 54.5 ,50.4 ,44.7 percent respectively. kd coefficient was,0.173day-1. aim of this bench scale study is determination of aerobic digest...

New stations (such as metro stations) will bring remarkable changes to the local transportation and economic development. Understanding patterns of factors which importantly impact on public transit ridership in surrounding areas new is essential their construction planning, like estimating possible ridership. Built environment variables with high importance magnitude, were thought applicable e...

A primary extra-adrenal retroperitoneal ganglioneuroma was found incidentally in a 22-year-old woman during screening for suspected pregnancy by transvaginal ultrasonography (TVS) and subsequently magnetic resonance imaging (MRI). TVS MRI revealed well defined solid mass at the level of L5 to S2 vertebrae displace right common iliac external vessels. Limited cuts region Computed tomography (CT)...

The human musculoskeletal system interacts with other objects in the environment. The hypo or/and hyperkinetic character of interactions causes changes of the rheological properties in connective tissue. This paper shows case studies that indicate the advantages of using TVS method for the identification and classification of the human axial system changes in different physical activities. The ...

This prospective randomized study was carried out in the department of Radiology and Imaging in collaboration with the department of Obstetrics and Gynecology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag and Dhaka Medical College Hospital (DMCH) during the period of January 2003 to December 2004. The aim of this study was to establish sonohyterography as a sensitive tool and ...

Transient voltage suppressor (TVS) has been widely used on the printed circuit board (PCB) to protect microelectronics system against system-level electrostatic discharge (ESD) and electrical fast transient/burst (EFT/B) events. However, signal integrity of operations may be destroyed after ESD EFT/B immunity test, if TVS were designed with a holding lower than operating CMOS ICs equipped in sy...

Transvaginal sonography (TVS) is now established as a first line imaging tool of choice for the preoperative assessment of endometriosis in women planning laparoscopy for surgical treatment of endometriosis.1,2 The evolution of TVS in the preoperative assessment of women with suspected endometriosis is a result of the technological advances in gynaecological ultrasound imaging tools and the eme...

The management and control of food waste is currently seen as a growing concern; anaerobic digestion promising alternative for the valorization waste. This study evaluates effect application three pretreatments (grinding, pH control, thermal treatment) organic load employing high alkalinity inoculum methane production through BMP tests, using Taguchi L8 experimental design 4 factors 2 levels, r...

Land cover classification (LCC) in complex surface-mined landscapes has become very important for understanding the influence of mining activities on the regional geo-environment. There are three characteristics of complex surface-mined areas limiting LCC: significant three-dimensional terrain, strong temporal-spatial variability of surface cover, and spectral-spatial homogeneity. Thus, determi...
