Current-Stress Tensor Commutators

Journal of Mathematical Physics, 1971
The model independent components of current-stress tensor equal time commutators are derived for arbitrary spin 0 and 1 systems.

Exercise Stress Testing Current Status

Cardiology, 1979
This paper is a review of the stress testing literature applying current methods of evaluation and analysis of exercise stress testing data to modern practice. Advantages and disadvantages of various methods for stress testing are discussed. Interpretation of the exercise stress test and an extensive discussion of 'false positive tests' as well as ...

Stresses in Current Medical Bibliography

New England Journal of Medicine, 1962
FROM the earliest days, scientists have exchanged visits and personal correspondence, and they have met together in conferences and societies to share information on their work. This is the oldest element of the communication system of science, and under the increased traffic of today it still provides an important link.

Oxidative Stress and Hypertension: Current Concepts

Current Hypertension Reports, 2010
Hypertension is a major contributor to the development of renal failure, cardiovascular disease, and stroke. These pathologies are associated with vascular functional and structural changes including endothelial dysfunction, altered contractility, and vascular remodeling. Central to these phenomena is oxidative stress. Factors that activate pro-oxidant

Stress Fractures: Current Concepts

2017
A stress fracture is a partial or complete solution of continuity in the bone, which can result from excessive repeated loads at submaximal intensity, resulting in greater bone reabsorption without equivalent bone ingrowths. Stress fractures in football players are particularly difficult to diagnose and treat, because of the specificity of the modality

Current Guidelines on Stress Ulcer Prophylaxis

Drugs, 1997
Acute uppergastrointestinal bleeding in intensive care unit (ICU) patients may occur due to peptic ulcer disease, adverse drug effects, gastric tube lesions, acute renal failure, liver failure or stress-induced gastric mucosal lesions. Gastric acid hypersecretion can be observed in patients with head trauma or neurosurgical procedures.

Stress fractures: Current concepts

Skeletal Radiology, 1978
1. Stress fractures result from muscular activity on bones rather than from direct impact upon them. 2. The fatigue variety of stress fracture occurs in normal bone when abnormal muscular tension or torsion is placed upon it. 3. The insufficiency type of stress fracture results when normal muscular stress is placed upon a bone with deficient elastic ...

Current Status of Measuring Oxidative Stress

2009
Although the healthcare field is increasingly aware of the importance of free radicals and oxidative stress, screening and monitoring has not yet become a routine test, since, dangerously, there are no symptoms of this condition. Therefore, in very few cases is oxidative stress addressed.

Stress induced leakage current in ultra-thin gate oxides after constant current stress

Microelectronic Engineering, 1997
Abstract Constant current stress induced leakage currents are studied in very thin oxide devices, for both stress polarities. This current has been investigated for both positive and negative gate voltage measurements. Stress induced leakage current (SILC) physical nature has been studied and an interpretation has been proposed, considering local ...

Patellofemoral Stress Syndrome

Sports Medicine, 1993
Patellofemoral stress syndrome is a condition of peripatellar pain without anatomic malalignment, history of trauma, patellar instability or clinical evidence of patellofemoral crepitus. These patients demonstrate lateral retinacular and iliotibial band tightness. Frequently, the patient's pain occurs when sitting for prolonged periods of time with the
