Reducing imperviousness connectivity by low impact developments or receiving pervious area (RPA) has been a regular strategy for runoff mitigation. However, the effects of RPA properties in combination with on have not fully discussed. In this study, two kinds are defined according to ponding volume: retention-dominated and conveyance-dominated. Runoff small urban catchment was evaluated under ...

The discharge of palm oil mill effluent (POME) without effective treatment is highly toxic to the environment and receiving waters due its high chemical oxygen demand , biochemical increased levels suspended solids. ponding system regarded as a conventional method for POME but requires long retention time extensive areas. Other processes, such physicochemical treatment, have also been applied t...

background: it seems necessary to assess dentists’ needs in order to upgrade the quality of the educational programs. this study was conducted to determine general dentists’ perspectives in the continuing educational programs in mazandaran province.    methods: this descriptive cross-sectional study was carried out among 430 dentists in mazandaran during 2011-2012. a questionnaire was distribut...

background osteotomy is one of the major steps in rhinoplasty. the aim of study was to compare edema and ecchymosis after external and internal lateral osteotomy in patients who underwent rhinoplasty. methods based on a prospective randomized clinical trial, 168 osteotomies were performed through an external route in a perforating fashion and internal route in a continuous fashion at right or l...

Ponding system or land application techniques are widely used at industrial scale to treat palm oil mill effluent (POME) prior discharge the environment. POME is considered as one of major problems that has generated voluminously from industries. The main purpose this article organize scattered available information on various aspects and a wide range promising current treatments including biol...

This paper deals with continuous frames and continuous Riesz bases. We introduce continuous Riesz bases and give some equivalent conditions for a continuous frame to be a continuous Riesz basis. It is certainly possible for a continuous frame to have only one dual. Such a continuous frame is called a Riesz-type frame [13]. We show that a continuous frame is Riesz-type if and only if it is a con...

background: identification of disease risk factors can help in the prevention of diseases. in assessing the predictive value of continuous variables, a routine procedure is to categorize the factors. this yield to inability to detect non‑linear relationship, if exist. multivariate fractional polynomial (mfp) modeling is a flexible method to reveal non‑linear associations. we aim to demonstrate ...

the continuous filter is a kind of sand filter, which will operate without any interruptions for backwashing and also it accepts high-suspended solid levels in feed stream. fouled sand is continuously removed from the filter bed, washed and recycled back without interruption with filtration process. various samples of water with certain amounts of turbidity enter through a feed pipe and being d...

labor pain is one of the most tiresome types of pain. so human has been seeking to allay this pain until now. administration of a suitable agent such as entonox during labor is very beneficial for childbirth outcomes. entonox can be administered in two ways: intermittently and continuously. the aim of this study is to demonstrate whether continuous method is as safe as intermittent method? this...
