in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
UNLABELLED Nicorandil, a hybrid adenosine triphosphate (ATP)-sensitive potassium channel opener and nitrate, is commonly used for the management of acute ischemic heart failure (AIHF). The aims of this study were to predict the effect of nicorandil by calculating myocardium-to-background ratio increasing rate (MBR-IR) using nicorandil stress myocardial perfusion SPECT and to evaluate the progno...
A combined approach of treating domestic wastewater using microbial fuel cell (MFC) and membrane bioreactor (MBR) has been developed as a promising and reliable technology of wastewater treatment. Treatment of wastewater in a single stage MFC has limitation to achieve the required treatment efficiency and utilize the effluent for irrigation or any other possible reuse without further treatment....
در این تحقیق، مشخصات لجن مازاد حاصل از یک فرایند تلفیقی رشد ثابت با بستر شناور و بیوراکتور غشایی و یک بیوراکتور غشایی متعارف در مقیاس پایلوت بررسی شد و مشخصات کیفی لجن شامل: svi، غلظت ازت و فسفر در جرم خشک، fi، میزان مصرف پلیمر، درجة تثبیت لجن و غلظت eps و smp اندازه گیری شد. با درنظرگرفتن شرایط بهره برداری مشابه (بار آلی، f/m، hrt، دما و ph) برای راکتورها، تفاوت های معناداری در شاخص های لجن آن...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
A novel nanofiltration membrane bioreactor (NF-MBR) was constructed by integrating a loosely structured hollow fiber into an aerobic activated sludge system. In order to verify the feasibility of loose NF bioreactor, parallel experiments conventional ultrafiltration (UF-MBR) and NF-MBR were conducted investigate process performances, fouling characteristics. The showed relatively high permeabil...
this study considers the level of increase in customer satisfaction by supplying the variant customer requirements with respect to organizational restrictions. in this regard, anp, qfd and bgp techniques are used in a fuzzy set and a model is proposed in order to help the organization optimize the multi-objective decision-making process. the prioritization of technical attributes is the result ...
BACKGROUND Shortened (12 months) multidrug multibacillary regimen (MDT MBR) was implemented in India in 1998, however there is yet a paucity of crucial data on its long-term outcome. OBJECTIVE To assess the efficacy of 12 months MDT MBR in multibacillary (MB) patients at our centre. DESIGN This was a retrospective study undertaken analysing the clinic records of 1210 patients registered at ...
