A hypothesis for the prediction of the circumferential wavenumber of buckling of the thin axially-compressed cylindrical shell is presented, based on the addition of a length effect to the classical (Koiter circle) critical load result. Checks against physical and numerical experiments, both by direct comparison of wavenumbers and via a scaling law, provide strong evidence that the hypothesis i...

Abstract The purpose of the study is to determine performance control system floater glider a predetermined location. method used was combination between software simulation and an experimental free-running test. Floater equipped with GPS as input output sensors coordinates or waypoints. microcontroller mounted Pixhawk 2.4.8 based on ARM cortex M4 – 32 bits. driven by two Brushless DC motors se...

In paediatric Asthma, involvement of caregivers is essential, therefore a satisfactory level parental knowledge influences the effectiveness treatment bronchial asthma as an important part in prevention exacerbations and complications hypothesis this research that good about among asthmatic children's can lead to better control asthma.

An increase in concurrent working memory load has been shown to amplify the attentional blink. The present study investigated the temporal locus of this phenomenon, by using a dual rapid serial visual presentation paradigm that enabled the measurement of lateralized event-related potentials. The P3 component was shown to be affected by both working memory load and the lag between the target sti...

Typical clinical features of cluster headache (CH) include circadian/circannual rhythmicity and ipisilateral cranial autonomic features. This presentation has led to the assumption that the hypothalamus plays a pivotal role in this primary headache disorder. Several studies using neuroimaging techniques or measuring hormone levels supported the hypothesis of a hypothalamic involvement in the un...
