Natural-fiber-reinforced composites offer various advantages over synthetic composites, including low density, useful mechanical properties and environmental friendliness. In spite of the progress achieved in field, performance these composite materials has yet to be fully characterized, particularly terms impact resistance. this study, we measured drop weight impact, Izod strength, hardness, t...

The self-compacting concrete (SCC) was invented to overcome the compaction problems in deep sections, owing its perfect workability characteristics. Steel fibers when used with SCC would affect required fluidity characteristics but improve impact resistance. In this research, an experimental work conducted evaluate response of micro-steel fiber-reinforced SCC, under flexural impact. A 5.47 kg f...

After 12 months of insulin therapy, mean body weight had increased by 3.06 2.5 kg (P < 0.001). The drop in HbA1c was correlated with insulin-associated weight gain. With the use of a multiple linear regression model, a cluster of variables was identified that significantly related to weight gain. Diabetes-related distress, initial insulin dose, and the increase of insulin dose during the course...

BACKGROUND A study was conducted to determine the reliability and validity of a new foot mobility assessment method that utilizes digital images to measure the change in dorsal arch height measured at 50% of the length of the foot during the Sit-to-Stand test. METHODS Two hundred - seventy five healthy participants participated in the study. The medial aspect of each foot was photographed wit...

BACKGROUND Attrition is a problem among patients who participate in commercial weight loss programs. One possible explanation is that if patients are unable to reach a weight that they expect to achieve, they may be more likely to drop out of treatment. This study investigated variables associated with attrition among 30 obese patients who completed a liquid meal replacement program (LMR) and e...

A three-dimensional (3D) finite element model (FEM) that simulates the Impactor weight-drop experimental model of traumatic spinal cord injury (SCI) was developed. The model consists of the rat spinal cord, with distinct element sets for the gray and white matter, the cerebrospinal fluid (CSF), the dura mater, a rigid rat spinal column, and a rigid impactor. Loading conditions were taken from t...

In this study, the pressure drop for the binary mixtures of particles differing in size and density in a pseudo-2D spouted bed was experimentally studied. A binary mixture of solid particles including sand, Gypsum, and polyurethane was used in the experimental setup. Effects of static bed height, cone angle, particles diameter, and a particles weight fraction on the bed pressure drop were e...

this study was designed to develop a modified tbi weight drop model for induction of focal mild cerebral injury. a stereotaxic coupled weight drop device was designed. principle arm of device carries up to 500g weights which their force was conveyed to animal skull through a thin nail like metal tip. to determine the optimal configuration of the device to induce mild tbi, six different trials w...

This graph shows two important results. First, as a group, patients lose a great deal of weight over time, and tend to keep much of it off. For these patients, average excess weight loss at 2 years is 80%, at 4 years is 64%, and 5 years 65%. We do not have enough data to calculate a meaningful average beyond 5 years. Second, there is a great deal of variation among patients. Some drop to a norm...
