Three readback signal detection methods are inyestgated for real-time flying height or head disk spacing variation measurement under vibration conditions. This is carried out by theoretical analysis, numerical simulation, and experimental study. The first method (amplitude detection) provides a simple way to study the head disk spacing change. The second method ( PW50 parameter estimation) can ...

INTRODUCTION Secular changes in the head and body dimensions of the Japanese population were recorded during the last century, but studies on Japanese adult facial shape were poorly documented. This study aimed to document the secular changes in facial shape and their association with craniofacial measures of Japanese adult female students. METHODS Data were collected from 1998-2001 and 1975-...

Background: Silymarin is a potent inhibitor of apoptosis. The present study aimed to investigate the effect of prenatal silymarin administration during the gestational period on fetal growth. Methods: This experimental study was conducted on 24 virgin female BALB/c mice weighing 20-30 grams. One male animal was caged with two females overnight, and they were examined for the presence of a vagi...

OBJECTIVES Commercially available football head protectors were tested to determine their impact energy attenuation performance and ability to reduce the likelihood of concussion. METHODS Prospective study using standardised impact test methods with both rigid (magnesium) and Hybrid III headforms. RESULTS Eight commercially available head protectors from six manufacturers were tested. The m...

The determination of plausibility of an injury arising from a fall leading to head trauma is a great challenge especially in young children. The present review is aimed to discuss important developments in the filed of head trauma cases especially in children. We explored various studies pertaining to head trauma injuries in children by exploring mainly PubMed, Google scholar and some library p...

This study explored the radiographic and anatomical differences in normal shoulders between men and women, as well as factors such as race, height, weight, and age. A total of 205 patients with documented normal anatomical radiographs comprised the study population. Five fellowship-trained orthopedic surgeon reviewers measured head diameter, humeral head size, head to tuberosity distance, great...

background: detection of women at risk for dystocia will allow physicians to make preparations and treatment decisions that can minimize maternal and neonatal morbidity. we aimed to determine the risk factors for dystocia in nulliparous women. methods: this case series enrolled 447 nulliparous women who presented with a single pregnancy in the vertex presentation and gestational age of 38-42 we...
