How similar must two successively presented patterns be for phi movement to be perceived between them? Phi movement between two granular patterns, one being the photographic negative of theother, appeared to be rater&, towards the direction of the earlier stimulus. Moving objects, dis-played on a TV picture which was made positive and negative on alternate frames, appeared to move backw...

The behaviour of antioxidant in polymers differs markedly depending on the type of test used. The performance of antioxidants can be optimized on the basis of intrinsic activity, compatibility with the polymer and rate of loss from the polymer by volatilization. Molecular interactions in antioxidants and stabilizers have a profound effect on all these factors which may be influenced in opposite...

Zinc (Zn) stable isotopes can record information about important oceanographic processes. This thesis presents data on Zn isotopes in anthropogenic materials, hydrothermal fluids and minerals, cultured marine phytoplankton, natural plankton, and seawater. By measuring Zn isotopes in a diverse array of marine samples, we hope to understand how Zn isotopes are fractionated in the oceans and how Z...

Catheter ablation of ventricular tachycardia (VT) associated with structural heart disease is still challenging. An epicardial approach often needed for patients or subepicardial arrhythmogenic origins ventricles. However, even after a successful in the space, limited no radiofrequency (RF) catheter can be performed owing to proximity phrenic nerve (PN) coronary artery.1Baldinger S.H. Kumar S. ...

The use of acoustic resonators for sensors application has opened a new branch in research and applications of piezoelectric materials and devices. The first generation of such sensors is constituted by the quartz crystal microbalance (QCM) based on AT-cut mono-crystalline quartz. High sensitivities of gravimetric sensing in both air and liquids were demonstrated. Since the 1980s, when the firs...

•Environmental- and dietary-driven seasonality in laboratory test data is well known•Population-wide Danish lab were related to mortality, sex, age trends•A seasonal reference interval modification method proposed•Seasonal improved association rates with diagnoses In health care, tests are used help determine a diagnosis follow patients over time. Test results typically calculated from sampled ...

This ensures the protection of both public healthcare workers. However, act shackling pregnant violates principles ethics that physicians are supposed to uphold. paper will explore how principle justice beneficence, making practice unethical. INTRODU...

Multiple endocrine neoplasia type 1 (MEN1) is classically characterized by the development of functional or nonfunctional hyperplasia or tumors in endocrine tissues (parathyroid, pancreas, pituitary, adrenal). Because effective treatments have been developed for the hormone excess state, which was a major cause of death in these patients in the past, coupled with the recognition that nonendocri...
