BACKGROUND Low-back disorders are related to biomechanical demands, and nurses are among the professionals with the highest rates. Quantification of risk factors is important for safety assessment and reduction of low-back disorders. OBJECTIVE This study aimed to quantify physical demands of frequent nursing tasks and provide evidence-based recommendations to increase low-back safety. METHO...

work done in the past. This is an experiment which, if it is to be successful , will have to combine all that is good in the old system with the advantages and good points of the new. It is an experiment in which I personally believe the Cinderella of Medicine will become the most attractive branch of medicine. One of the great dangers of State medicine is that it may become impersonal. There i...

This article describes the contents of a standard hospital resuscitation trolley for cardiopulmonary resuscitation. Each item is discussed in terms of its function and the rationale for its inclusion.

<p class="Abstract">The tool used to carry goods is a trolley. To simplify the process of carrying using trolley, trolley can be combined with robot technology. In order for see objects or surrounding atmosphere, it needs sense that integrated sensory system presence an object, namely ultrasonic sensor. An sensor device captures motion object and converts into sound reflection read proces...

Overhead cranes are under-actuated systems. They have three outputs that need to be controlled, consisting of cargo swing angle, trolley displacement, and suspended cable length, but only two actuators: cargo lifting and trolley driving forces. The main objective of this study is to design a robust controller for an overhead crane that transfers cargo from point to point as fast as possible and...

Ethical thought experiments such as the trolley dilemma have been investigated extensively in the past, showing that humans act in a utilitarian way, trying to cause as little overall damage as possible. These trolley dilemmas have gained renewed attention over the past years; especially due to the necessity of implementing moral decisions in autonomous driving vehicles (ADVs). We conducted a s...

Two experiments, which included 3 incubators, were carried out to investigate the effects of egg weight and position relative to incubator (setter) fan on embryonic mortality, second quality chicks, and fertile hatchability of broiler eggs. Three egg weight groups termed small (approximately 62.4 g), average (approximately 65.4 g), and large (approximately 68.9 g) were set in either the incubat...
