The effects of initial spacing layout on some allometric characteristics of 12-year-old Quercus castaneifolia trees grown in Central Mazandaran, north of Iran were examined. Trees were planted in 5 different layouts (1?1, 1.5?1.5, 2?2.5, 2?3 and 4?4 m). Tree height, diameter at breast height, natural pruning height and the survival of trees were recorded in each sample plot. Tree basal area and...

greenhouse structure has an important role in success of greenhouse production. this research was conducted to study problems related to vegetable greenhouse structure in khuzestan province for on year(2011-2012). for this purpose, 21 greenhouses were selected by simple randomized samplang and questionnaires were completed. the results revealed that the major problems in greenhouses vegetable p...

Background: Obesity is a coronary risk factor associated to myocardial infarction although waist to-hip-ratio has shown higher predictive power. Objective: The aim of this study was a Receiver Operating Characteristic anthropometric analysis in infarcted males to identify the strength of association for simple measurements, obesity and indicators such as, waist to-hip-ratios, waist to-height-r...

OBJECTIVE Falls from height cause significant mortality in the urban environment, but reliable prognostic factors have not been identified. Even the intuitive relation between the distance fallen and mortality rate has been questioned. Our objective was to determine factors predictive of increased mortality rate in victims of falls from height. DESIGN Clinical observational study, retrospecti...

BACKGROUND Several scoring systems for cervical disc and facet joint degeneration, using radiography or computed tomography, have been developed and tested for reliability. However, definitions of disc height and facet joint space narrowing vary. To our knowledge, no study has reported quantitative data for normal radiologic values of the cervical spine in the Korean population. The purpose of ...

OBJECTIVES While researchers are increasingly recognizing the importance of adjusting waist circumference (WC) for height, no standard has yet been established. In this study we contrast three standard methods for indexing WC by height (using height, root-height and height-squared) via comparisons with age-specific optimal indices. STUDY DESIGN AND SETTING Measurements from 722 male and 746 f...

this study investigates the amount of suspended solid particles in three drinking water wells, conducted several times per day in the city of mashhad. the results have also been used for the review and optimization of tested hydro-cyclones. for this purpose, 18 different hydro-cyclones, based on the experimental design process of the taguchi method, were designed and the affecting factors were ...

AIM To compare the associations of several anthropometric indices (i.e. waist circumference [WC], waist-to-height ratio, body mass index (BMI) and waist-to-hip ratio) with the insulin resistance (IR) proxy measures in Greek schoolchildren. METHODS A random sample of 248 children was used. Fasting plasma glucose and serum insulin levels were measured. IR was estimated through homeostasis model...

The purpose of this study was to determine whether symphysis morphology could be used as a predictor of the direction of mandibular growth and to assess growth changes of the symphysis. Cross-sectional data included lateral cephalometric radiographs of 115 adults (58 women, 57 men) with the longitudinal sample a subset of 62 subjects (30 females, 32 males) at four age groups. The direction of m...
