Microsrip Ring Antennas Operating at Higher-Oder Modes for Mobile Communications [PDF]

open access: yes, 1995
An experimental study of microstrip ring antennas suitable for use in mobile communication systems is presented. Conical radiated beams are generated by the TM(21) and TM(41) modes.

Posttetanic potentiation improves neuromuscular efficiency of mouse muscle in vitro

open access: yesPhysiological Reports, 2022
Neuromuscular efficiency is defined as the ratio of work output to stimulation rate. The purpose of these experiments was to test the hypothesis that neuromuscular efficiency would be increased in proportion to posttetanic potentiation, that is, the ...

The Eccentric Phase in Unilateral Resistance Training Enhances and Preserves the Contralateral Knee Extensors Strength Gains After Detraining in Women: A Randomized Controlled Trial

open access: yesFrontiers in Physiology, 2022
The current randomized controlled study investigated whether or not the inclusion of the eccentric phase in resistance training favors the contralateral strength gains after different unilateral protocols, and whether such gains are retained after ...

Cardiovascular and Muscular Consequences of Work-Matched Interval-Type of Concentric and Eccentric Pedaling Exercise on a Soft Robot

open access: yesFrontiers in Physiology, 2017
Eccentric types of endurance exercise are an acknowledged alternative to conventional concentric types of exercise rehabilitation for the cardiac patient, because they reduce cardiorespiratory strain due to a lower metabolic cost of producing an ...

Maximum Strength Benchmarks for Difficult Static Elements on Rings in Male Elite Gymnastics

open access: yesSports, 2021
On rings, in men’s artistic gymnastics, the general strength requirements for important static elements remain elusive. Therefore, the aim was to describe the relationship between a new conditioning strength test and a maximum strength test of static ...

The Role of Extracellular Signal-Regulated Kinase Pathways in Different Models of Cardiac Hypertrophy in Rats

open access: yesBiomedicines, 2023
Cardiac hypertrophy develops following different triggers of pressure or volume overload. In several previous studies, different hypertrophy types were demonstrated following alterations in extracellular signal-regulated kinase (ERK) pathway activation ...

A CONCENTRATING DIALYZER [PDF]

open access: yesJournal of Experimental Medicine, 1930
An apparatus is described for dialyzing aqueous solutions and simultaneously concentrating them to a thick syrup, or even to dryness. The fluid is placed in collodion bags with reservoir bulbs open to atmospheric pressure. The bags are surrounded by flowing cold water, under negative pressure, and are subjected of a rocking motion.

Satellite cell activity is differentially affected by contraction mode in human muscle following a work-matched bout of exercise

open access: yesFrontiers in Physiology, 2014
Optimal repair and adaptation of skeletal muscle is facilitated by resident stem cells (satellite cells). To understand how different exercise modes influence satellite cell dynamics, we measured satellite cell activity in conjunction with markers of ...

Can Countermovement Jump Neuromuscular Performance Qualities Differentiate Maximal Horizontal Deceleration Ability in Team Sport Athletes?

open access: yesSports, 2020
This investigation aimed to determine the countermovement jump (CMJ) neuromuscular performance (NMP) qualities that differentiate between athletes with high or low horizontal deceleration ability.

Obese subjects show sex-specific differences in right ventricular hypertrophy [PDF]

open access: yes, 2014
As right ventricular (RV) remodeling in obesity remains underinvestigated, and the impact of left ventricular (LV) diastolic dysfunction on RV hypertrophy is unknown, we aimed to investigate whether (1) sex-specific patterns of RV remodeling exist in ...
