The effect of land cover change, from natural to anthropogenic, on physical geography conditions has been studied in Kayisdagi Mountain. Land degradation is the most important environmental issue involved in this study. Most forms of land degradation are natural processes accelerated by human activi …

South Korea's Hyundai Motor Group said Friday its affiliates and its chairman will buy an 80-percent stake, worth up to 900 billion won ($828 million), in US robotics firm Boston Dynamics Inc. in the latest move to propel its future mobility business. The board of directors at Hyundai Motor and its two affiliates, Hyundai Mobis and Hyundai Glovis, approved the plan to acquire the controlling stake in Boston Dynamics...

Metallurgical and Materials Transactions A - Nitinol has revolutionized many traditional engineering designs with its unique properties that include pseudoelasticity and the shape-memory effect...

Background: Systemic mastocytosis is an uncommon disease caused by an invasion of abnormally proliferating neoplastic mast cells into multiple tissues. Although

Research into the use of transitional objects (Winnicott, 1971) by adult clients in psychotherapy has given little attention to the question of how a transitional object (TO) works. This question is addressed through the use of a semi-structured interview. Data was collected on the clinical practice …

In a pilot study, we had five typical Internet users evaluate the quality of health websites returned by a general-purpose search engine (Google) and a healthcare-specific search engine (Healthfinder). The evaluators used a quality criteria developed by Mitretek/Health Information Technology Institu …

Bone marrow stem cells give rise to a variety of hematopoietic lineages and repopulate the blood throughout adult life. We show that, in a strain of mice incapable of developing cells of the myeloid and lymphoid lineages, transplanted adult bone marrow cells migrated into the brain and differentiate …

Soft actuators have opened avenues for the design of robots that excel in unstructured environments. Electrohydraulic soft actuators are liquid-filled shells that deform due to electrostatic forces. This working principle enables large design freedom and actuator performance that rivals natural muscle. However, the fundamental physics that governs the dynamics of electrohydraulic soft actuators is virtually unexplored. Here, we show how scale, geometry, and materials system of the actuators, as well as external applied loads and voltages lead to actuation speeds that span multiple orders of magnitude. The presented principles and conclusions can readily be applied to analyze the dynamic behavior of various types of electrohydraulic actuators and to provide guidelines on how to increase actuation speed in bio-inspired robotic systems.

Osteopenia is a decrease in the amount of calcium and phosphorus in the bone. This can cause bones to be weak and brittle. It increases the risk for broken bones.

Osteoporosis is a metabolic bone disease characterized by loss of bone mass and strength, resulting in increased risk of fractures. It is classically divided into primary (post-menopausal or senile), secondary and idiopathic forms. There are many rare ...

Stem cells are found in various organs where they participate in tissue homeostasis by replacing differentiated cells lost to physiological turnover or injury. An investigation was performed to determine whether stem cells are restricted to produce specific cell types, namely, those from the tissue …

Senior appreciation! Colton was a dynamic player and a great teammate. He will be missed but success in life is waiting for him! #pctproud #GoPCTBaseball #studentathlete pic.twitter.com/PDC1d9ok1H— PCT Baseball (@PCTBaseball) March 31, 2020
