abstract the current research tried to examine the impact of multiple intelligence (mi) and its components on multiple choice (mc) and open ended (oe) reading comprehension tests. ninety six students of high school in grade four took part in this study. to collect data, participants completed multiple intelligence (mi) questionnaires along with a multiple choice (mc) and open ended (oe) forms ...
Antecedentes: la presencia de hipertrofia ventricular izquierda (HVI) es un marcador pronóstico y severidad en condiciones sobrecarga presión. Se determina por masa (MV) aumentada el ecocardiograma, debiéndose ajustar MV tamaño corporal pediatría (normalización). Existen múltiples métodos normalización, pero se desconoce si estos son comparables. Objetivo: comparar distintos normalización sujet...
In this research, progressive damage of woven composite materials due to high velocity impact is investigated via finite elements method. Necessity of impact analysis of composite materials using progressive damage method is detailed and available material models for this type of analysis is discussed. Governing equations at onset of failure and failure modes as well as damage growth is express...
INTRODUCTION Hollow viscus injuries (HVIs) are uncommon but potentially catastrophic conditions with high mortality and morbidity rates. The aim of this study was to analyze our 16-year experience with patients undergoing surgery for blunt or penetrating bowel trauma to identify prognostic factors with particular attention to the influence of diagnostic delay on outcome. METHODS From our mult...
composite pressure vessel cng made of epoxy – carbon material with nonmetal liner is 60% lighter than aluminum vessel under the same conditions. one of the important parameters in the pressure vessels design is their resistance against impact and prevention of explosion. in this paper, the effects of low velocity impact on composite pressure vessel are investigated using fe analysis. the vessel...
Purpose: Despite advances in diagnostic and imaging technologies, the diagnosis of traumatic hollow viscus injury (HVI) remains a great challenge clinical practice. This study aimed to determine accuracy computed tomography (CT) HVI emergent blunt trauma patients.Methods: The was conducted on patients with abdominal who were admitted our center, regional emergency Kyung Hee University Medical C...
The passive shielding of space craft structures is critical due to the increase in demand for lightweight protection, which required counter damaging effects micro-meteoroid orbital debris (MMOD) on unmanned spacecraft, have steeply increased recent years. Research hypervelocity impact (HVI) led development shield configurations such as conventional Whipple shield, consists two plates separated...
