The aim of this paper is to study the local Nusselt number of the symmetrical liquid-liquid jets emitting from a nozzle. Equations obtained from theoretical works are arranged in the form of a computerized model. The validity of this model was tested by the data from an experimental paper [1]. After few adjustments the model predicted the experimental data with a reasonable accuracy. Making...

Nursing students face stressful situations during a clinical training. This two-wave (between June and December 2004) study explored the relationship between the coping styles and stressful life events in terms of the occurrence of depression and anxiety among 97 Japanese female nursing students before (Time 1) and after (Time 2) a clinical training. In a structural equation modelling, Time 2 d...

The aims of this study were to establish and validate various predictive equations of half-marathon performance. Seventyeight half-marathon male runners participated in two different phases. Phase 1 (n = 48) was used to establish the equations for estimating half-marathon performance, and Phase 2 (n = 30) to validate these equations. Apart from half-marathon performance, training-related and an...

There is little information on the application of generalized prediction equations to ethnic groups other than Europeans and groups of European descent. The purpose of this study was to crossvalidate conventional equations on a group of 56 Chinese adults. Body density was assessed by underwater weighing and also predicted by equations which use a combination of selected skinfolds-biceps, tricep...

OBJECTIVE To compare measured resting energy expenditure to resting energy expenditure predicted from eight published prediction equations in a sample of patients with pancreatic cancer. DESIGN Cross-sectional study. SETTING Ambulatory patients of a tertiary private hospital. PARTICIPANTS Eight patients with pancreatic cancer (5 males, 3 females; age: 62.0+/- 5.2 years; BMI: 24.4+/- 3.2 k...

mashhad plain is one of the most important regions of apple cultivated areas. occurring spring late frost creates a lot of damages on bud and decreasing the yield of apple in this region. assessment and risk modeling of frost damage would be useful to manage and decrease the damage. the study area is a part of khorasan razavi province which is located in mashhad plain. this region is located in...

OBJECTIVES We sought to determine a generalized equation for predicting maximal heart rate (HRmax) in healthy adults. BACKGROUND The age-predicted HRmax equation (i.e., 220 - age) is commonly used as a basis for prescribing exercise programs, as a criterion for achieving maximal exertion and as a clinical guide during diagnostic exercise testing. Despite its importance and widespread use, the...

OBJECTIVES To develop an equation to predict dual plasma sample method (DPSM) (99m)Tc-diethylene triamine pentaacetic acid ((99m)Tc-DTPA) plasma clearance from single plasma sample method (SPSM), and to clarify the condition in which DPSM can be substituted by SPSM in measurement of glomerular filtration rate (GFR). METHODS Patients with chronic kidney disease (CKD) were selected. Watson modi...

To comprehend dynamic behaviors of biological systems, many models have been proposed. These models need literatures data to represent detailed and accurate dynamics. However, those data are sufficient only in few cases. To solve this problem, many techniques have been developed, including Genetic Algorithm (GA). Those methods require defining equations before predicting biological systems. To ...
