drilling is one of the main machining processes carried out in the assembly stage of automobile manufacturing and aerospace components. generally, delamination is considered as a major problem during drilling of composite materials. in this paper, the effects of feed rate, cutting speed and drill point angle on thrust force and delamination factor have been studied by using full factorial desig...
The present study was performed to investigate the effects of dietary electrolyte balance and probiotic on the performance and carcass characteristics in Japanese quail under heat stress conditions. A total of 672 quail chicks (20-day old) were studied in a three-factor, factorial experiment with 4 replicates and in each replication of 14 birds during 20 to 37 and 20 to 41 days Factors included...
Objective: Considering the use of triple antibiotic paste (TAP) for root canal treatment of open apex teeth, this study aimed to assess the effect of TAP and calcium hydroxide (CH) on bond strength of composite to dentin. Methods: This in-vitro study was conducted on 32 extracted human premolar teeth. After disinfection with 2% thymol solution, the enamel on the buccal surface of specimens ...
Face recognition is supposed to be fast. However, the actual speed at which faces can be recognized remains unknown. To address this issue, we report two experiments run with speed constraints. In both experiments, famous faces had to be recognized among unknown ones using a large set of stimuli to prevent pre-activation of features which would speed up recognition. In the first experiment (31 ...
The purpose of this study was to investigate the effect of process conditions on the properties of instant grain base. A blend of wheat, mungbean and groundnut was used in the study. The effects of feed moisture, barrel temperature and screw speed on product responses viz. specific mechanical energy (SME), expansion ratio (ER), density (D), water absorption index (WAI) and water solubility inde...
Machining of hard materials is a recent technology for direct production of work-pieces. The primary challenge in machining these materials is selection of cutting tool inserts which facilitates an extended tool life and high-precision machining of the component. These materials are widely for making precision parts for the aerospace industry. Nickel-based alloys are typically used in extreme e...
Introduction: Admission and medical record system (AMRS) is one of the most important subsystems of hospital information system, which is used by many users in admission, discharge, and health information management. Interface usability problems can reduce user speed, precision, and efficiency in user-system interaction. This study aimed to identify the usability problems of AMRS in a hospital ...
