Experimental Investigations of Using Aluminum Oxide (AlO) and Nano-Graphene Powder in the Electrical Discharge Machining of Titanium Alloy.

In the present study, a comprehensive parametric analysis was carried out using the electrical discharge machining of Ti6Al4V, using pulse-on time, current, and pulse-off time as input factors with output measures of surface roughness and material removal rate. The present study also used two different nanopowders, namely alumina and nano-graphene, to analyze their effect on output measures and surface defects. All the experimental runs were performed using Taguchi's array at three levels.

Virtually Accompanied Eating in the Outpatient Therapy of Anorexia Nervosa.

Background: Normalizing the eating pattern and weight recovery are the main objectives in treating anorexia nervosa (AN). Eating accompaniment through shared mealtimes is a common strategy in eating disorder management programs. This study aims to examine the impact on weight gain of an internet-delivered meal support group on patients with AN who were under ambulatory treatment with the Eating Disorders Unit of the UC Christus Health Network, Chile.

Intelligence Quotient (IQ) in school-aged preterm infants: A systematic review.

Unlabelled: Preterm birth (before 37 weeks of gestational age) is associated with certain risks to child development. The aim of this systematic review was to summarize available and updated empirical evidence on prematurity as a risk factor for cognitive development in school age. Thus, we attempted to identify similarities and differences with the full-term population and to point out possible risk or protective factors among the biological, psychosocial and family variables.

The establishment of public health policies and the burden of non-alcoholic fatty liver disease in the Americas.

Non-alcoholic fatty liver disease (NAFLD) affects 20-25% of the general population and is associated with morbidity, increased mortality, and elevated health-care costs. Most NAFLD risk factors are modifiable and, therefore, potentially amenable to being reduced by public health policies. To date, there is no information about NAFLD-related public health policies in the Americas.

Multi-Response Optimization of Abrasive Waterjet Machining of Ti6Al4V Using Integrated Approach of Utilized Heat Transfer Search Algorithm and RSM.

Machining of Titanium alloys (Ti6Al4V) becomes more vital due to its essential role in biomedical, aerospace, and many other industries owing to the enhanced engineering properties. In the current study, a Box-Behnken design of the response surface methodology (RSM) was used to investigate the performance of the abrasive water jet machining (AWJM) of Ti6Al4V. For process parameter optimization, a systematic strategy combining RSM and a heat-transfer search (HTS) algorithm was investigated.
