BACKGROUND The purpose of this study is to determine the angulation of mandibular third molar in orthodontic cases which are planned for extraction and non extraction. METHODS This is a cross-sectional descriptive study in which pre-treatment panoramic radiographs of 49 patients, age range 11-26 years were taken from the OPD of Department of Orthodontics, Dr. Ishrat- ul -Ebad Khan Institute o...
BACKGROUND Class-1 malocclusion commonly presents with crowding and poses an aesthetic concern to patients. An orthodontist may encounter a variety of dental problems and must handle them strategically to establish adequate occlusal relationships. Hence, this study was conducted to evaluate the occlusal characteristics of patients who have undergone non-extraction or all first premolars extract...
BACKGROUND The aim of this study was to determine arch width changes during maxillary first premolars extraction and non-extraction treatment in patients with Class II division 1 malocclusion. MATERIAL AND METHODS Dental casts of 91 Class II division 1 patients (36 males and 55 females) were evaluated. The minimum age of the subjects at the beginning of treatment was above 16 years. 48 patien...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
In this study, solid state fermentation (SSF) was carried out to produce single cell protein (SCP) from sugarcane bagasse using Saccharomyces cerevisiae. The SSF experiment were performed in a tray bioreactor. The influence of several parameters including extraction buffer, initial moisture content of substrate, fermentation time, relative humidity in bioreactor, the bioreactor temperature and ...
The renewed interest in plant-derived drugs has led to an increased need for efficient extraction methods. The present investigation was an attempt to evaluate and compare the conventional methods of extraction with non conventional methods of extraction, such as ultrasonic-assisted extraction (UAE) and microwave-assisted extraction (MAE) methods. Pterocarpus marsupium Roxb. has been reported t...
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
simplification universal as a universal feature of translation means translated texts tend to use simpler language than original texts in the same language and it can be critically investigated through common concepts: type/token ratio, lexical density, and mean sentence length. although steps have been taken to test this hypothesis in various text types in different linguistic communities, in ...
This paper discusses modeling of non-uniform substrate resistivity for substrate resistance extraction. Though substrate resistivity of each substrate layer is frequently assumed to be uniform, doping profile of each substrate layer is not uniform. We present the extraction error of substrate resistance under uniform resistivity assumption. The resistivity models we suggest enable accurate resi...
Polystyrene-grafted-polyglycidol (PS-PG), a water-compatible resin, is applied for the extraction of precious metal in effluents of electroplating process. The extractions of gold (I) and silver (I) cyanide using this resin are investigated. More than 99% of gold and 99% of silver ions of the originally dissolved could be extracted from the aqueous phase to polymer phase. Recycling of the resin...
