بررسی فرایند الکتروفنتون به منظور تصفیه ی پساب شرکت پتروشیمی شازند و بهینه سازی عوامل موثر بر فرایند
هدف از این تحقیق بررسی کارایی فرایند الکتروفنتون و بهینه سازی پارامترهای موثر بر فرایند به کمک طراحی آماری به منظور تصفیه پساب شرکت پتروشیمی شازند میباشد.در این تحقیق تاثیر پارامترهای : زمان واکنش ، چگالی جریان، ph پساب ، نسبت (?ml h?_2 o_2)/( lit pw) و نسبت مولی (mol h_2 o_2)/(mol fe^(2+) ) بر حذف cod و color از پساب پتروشیمی تحت فرایند الکتروفنتون( با الکترود های آهن و آلومینیوم به طور جداگان...
Teleseismic converted phases are used to probe the composition of the downgoing oceanic crust as a function of depth along the Cocos slab in central and southern Mexico. Previously, modeling of the receiver function (RF) conversion amplitude of the flat Cocos slab beneath central Mexico at 45 km depth revealed a thin low-velocity upper oceanic crust of a thickness of 471 km, which has much lowe...
[1] One process for the formation of continental crust is the accretion of arc terranes at continental margins. A longstanding problem with this model is that although the composition of the continental crust is andesitic, the majority of arc lavas are basaltic. Moreover, those arc lavas that are andesitic tend to be evolved (lower Mg #) compared to the continental crust. Continental crust can ...
To the Editor: A 50‐year‐old man presented with recurrent episodes of bullae, erosions, and crust on sun‐exposed areas for 1 year. Lesions healed with scarring and hyperpigmentation. The skin lesions were aggravated after sun exposure. The patient had a 30‐year alcohol abuse (100–200 ml/day) history. Family heredity history was unremarkable. Physical examination revealed multiple erosions with ...
Intermediate-period Rayleigh and Love waves propagating across Tibet require marked radial anisotropy within the mid-lower crust, consistent with a thinning of it. The anisotropy is largest in the western part of the plateau where the moment tensors of earthquakes indicate active crustal thinning. A preferred orientation of mica crystals resulting from the crustal thinning can account for the o...
chaldoran area in nw of iran has mesozoic oceanic crust basement. the studied rocks of this region can be divided into three groups: ophiolitic gabbros and pillow lavas, ophiolitic volcanoclastics and eocene lava flows. ophiolitic mafic rocks show continental volcanic arc natures and eocene lava flow shows oib-like nature. during the mesozoic,the chaldoran region was situated in the active cont...
Fried products impose a health concerns due to considerable amount of oil they contain. Production of snack foods with minimal oil content and good management of oil during frying to minimize the production of toxic compounds continue to be challenging aims. This paper aims to investigate the possibility of producing a fat-free food snack by replacing frying oil with a nonfat medium. Glucose wa...
The Iranian Plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the Zagros and Alborz Mountains) and oceanic plate subduction (e.g. Makransubduction zone). To derive a detailed image of the crust–mantle (Moho) and lithosphere–asthenosphere (LAB) boundaries in some tectonically units of the Iranian Plateau, we used a large number of S receiver functio...
A principal data product from MESSENGER’s primary orbital mission at Mercury is a global multispectral map in eight visible to near-infrared colors, at an average pixel scale of 1 km, acquired by the Mercury Dual Imaging System. The constituent images have been calibrated, photometrically corrected to a standard geometry, and map projected. Global analysis reveals no spectral units not seen dur...
ABSTRACT: Acute urinary retention can occur following benign prostatic hyperplasia (BPH) , prostatic cancer ,urethral stone , neurogenic bladder and etc. Acute urinary retention presents with severe pain of suprapubic and discontinuation of voiding . Acute urinary retention has been reported following posterior urethritis and prostatitis, but it has not been reported following the crust due t...
