In the last tenyears, the use andapplications ofmathematicalmodellinghave increased inchemistry and food science and technology. However, it is still common to find researchers using the ‘one at a time’ approach to test and select variables to develop and optimize products and processes. In this regard, the objectives of this review are to provide some statistical information related to mathema...
Rise in temperature is inevitable orthopaedic drilling. Massive research had beendone the field of drilling to investigate effect cutting conditions, bone relatedparameters, and drill bit geometric parameters on heat generation minimum surrounding tissuesinjury. In present research, contradictory conclusions regarding conditions bitgeometric were observed. Minimum 31°C was achieved at speed 186...
Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...

The aim of this study was to optimize protease production using a novel Bacillus sp. ZR-5 strainisolated from the soil, and evaluate its application in detergent industry. The proteolytic activityof the strain was demonstrated using gelatin hydrolysis screening test. Protease productionoptimization was carried out using a two-step approach: a conventional method in order toidentify the best car...

abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
