This paper introduces Modified Altitudeand DiveGuidance laws for escaping a microburst with turbulence. First, a new safety metric is constructed that quantifies the aircraft upward force capability in a microburst encounter. In the absence of turbulence, the safety factor is shown to be a decreasing function of altitude. This suggests that descending to a low altitude may improve safety in the...

This contribution aims at showing some of the advantages of taking a novel, broad and systemic view on constitutive rules based on a failure oriented analysis, relying on the notion of impasse. Basically, impasses can descend by two main kinds of causes: either a mismatch between rules (how things should be done) and facts (how things are actually done), or an internal contradiction among rules...

HLH54F, the Drosophila ortholog of the vertebrate basic helix-loop-helix domain-encoding genes capsulin and musculin, is expressed in the founder cells and developing muscle fibers of the longitudinal midgut muscles. These cells descend from the posterior-most portion of the mesoderm, termed the caudal visceral mesoderm (CVM), and migrate onto the trunk visceral mesoderm prior to undergoing myo...

Acute uterine inversion is a rare and life-threatening post-partum complication which often occurs when the placenta fails to detach from the uterus after childbirth. The uterine fundus falls into the endometrial cavity and may descend to the cervix (incomplete) or beyond the cervix (complete). Death may occur in 15% of the affected mothers due to pain, blood loss and shock. The shock is often ...

An 87-year-old Asian male experienced progressive shortness of breath for two days. He presented symptoms and signs of decompens-ated heart failure and was diagnosed as non ST-segment elevation myocardial infarction, killip III. Coronary intervention was performed for chronic total occlusion of left anterior descend-ing artery. Unfortunately, coronary perforation happened during balloon anchori...

Spinal cord injury causes debilitating cardiovascular disturbances. The etiology of these disturbances remains obscure, partly because the locations of spinal cord pathways important for sympathetic control of cardiovascular function have not been thoroughly studied. To elucidate these pathways, we examined regions of the thoracic spinal cord important for reflex sympathetic control of arterial...

BACKGROUND Studies show that the well-prepared traveller is less likely to suffer travel related illness. This study is designed to examine trekkers' knowledge of altitude sickness in an attempt to see whether knowledge can protect against acute mountain sickness (AMS) and high altitude pulmonary or cerebral oedema (HAPE/HACE). METHODS A convenience sample of 130 trekkers were interviewed in ...

The multifunctional above-knee prosthesis WLP-7R (Waseda Leg Prosthesis - type 7 Refined) described in this study allows amputees to descend and ascend stairs with no external power sources. With the hydraulic circuit mounted in the shank, the ankle joint and the knee joint mutually conterbalance during stance phase in stair walking as well as level walking so that the following performances ar...
