we aimed to investigate the correlation of tonsillectomy with palatine tonsil size and to compare the differences of tonsil size and the need for surgery in children and adults. also we can predict the outcome of tonsillectomy. we measured tonsil sizes in (height and width) in 150 children and 35 adults with hypertrophy of palatine tonsils and we measured the mass of tonsils and then the data a...

in this study based on image analysis, an ore grade estimation model was developed. the study was performed at a limestone mine in central iran. the samples were collected from different parts of the mine and crushed in size from 2.58 cm down to 15 cm. the images of the samples were taken in appropriate environment and processed. a total of 76 features were extracted from the identified rock sa...

background: design of school furniture is one of the contributing factors to back pain among pupils. research has implicated that mismatch between school furniture and body size may be regarded as a causative factor for muculoskeletal disorders amongst pupils. to investigate the fitness between school furniture and pupils this study was designed and implemented in hamadan city, west of iran. me...

A full understanding of the characteristics of faults is crucial to several important research areas in testing and software maintenance. Applicable maintenance research areas include change impact analysis, maintainability, regression testing, and comparative evaluation of maintenance techniques. We explore the fundamental nature of faults by looking at the differences between a syntactic and ...

it is always attempted to reduce the costs of comminution in mineral processing plants. one of thedifficulties in size reduction section is not to be designed properly. the key factor to design size reductionunits such as crushers and grinding mills, is ore’s work index. the work index, wi, presents the oregrindability, and is used in bond formula to calculate the required energy. bond has defi...

Manpower Planning is the prerequisite for efficient management of any organization. The stability of the graded structure in corporate and government offices plays a dominant role for efficient planning and control of human resources. The constituent components of a manpower planning model are recruitment process, promotion process and leaving process. This paper addresses a two-graded manpower...

colorectal cancer is the second leading cause of cancer death worldwide. through risk assessment of malignancy in polyps, screening programs can achieve the best results. this study aimed to determine the association between the grade of dysplasia and the location of colorectal polyps. 240 colorectal adenomatous polyps which were referred to department of pathology at rasoul-e-akram hospital be...

Both molecular profiling of tumors and longitudinal tumor size data modeling are relevant strategies to predict cancer patients' response to treatment. Herein we propose a model of tumor growth inhibition integrating a tumor's genetic characteristics (p53 mutation and 1p/19q codeletion) that successfully describes the time course of tumor size in patients with low-grade gliomas treated with fir...

The purpose of this work is to compare the linear and non-linear kriging methods in the mineral resource estimation of the Qolqoleh gold deposit in Saqqez, NW Iran. Considering the fact that the gold distribution is positively skewed and has a significant difference with a normal curve, a geostatistical estimation is complicated in these cases. Linear kriging, as a resource estimation method, c...
