Matters of hospital management do not figure prominently on the medical ethics agenda. However, management decisions that have to be taken in the area of hospital care are in fact riddled with ethical questions and do have significant impact on patients, staff members, and the community being served. In this decision making process evidence based medicine (EBM) plays an increasingly important r...

We report on the experimental observation of an abrupt rise in the longitudinal momentum distribution of recoil ions created in proton helium collision. The details of this structure can be related to electrons traveling with the velocity of the projectile [electron capture to the continuum (ECC)]. The longitudinal as well as the transverse distribution of the recoil ions can be explained as a ...

BACKGROUND Little research has been carried out on whether the parental stress affects children's oral health in general and dental caries in particular. This study aimed to investigate the association between parental stress and early childhood caries (ECC). METHODS A cross-sectional study was designed that included 250 children of 4-6 year-old; 127 ones attended the pediatric department of ...

In the current work we propose two efficient formulas for computing the 5-fold (5P ) of an elliptic curve point P . One formula is for curves over finite fields of even characteristic and the other is for curves over prime fields. Double base number systems (DBNS) have been gainfully exploited to compute scalar multiplication efficiently in ECC. Using the proposed point quintupling formulas one...

The percentage of combat wounds involving the eyes, maxillofacial, and neck regions reported in the literature is increasing, representing 36% of all combat-related injuries at the start of the Iraq War. Recent meta-analysis of 21st century eye, maxillofacial, and neck injuries described combat injury incidences of 8% to 20% for the face, 2% to 11% for the neck, and 0.5% to 13% for the eye and ...

The status of experimental tests of general relativity and of theoretical frameworks for analysing them are reviewed. Einstein’s equivalence principle (EEP) is well supported by experiments such as the Eötvös experiment, tests of special relativity, and the gravitational redshift experiment. Future tests of EEP will search for new interactions arising from unification or quantum gravity. Tests ...

At the present time, there are many calls, mainly from the orthodox medical profession and regulatory authorities, for medical interventions of all types to be practised and regulated on the basis of whether they work as determined by clinical trials. Medicine of this sort is called ‘Evidence Based Medicine’ (EBM). On the surface, EBM seems eminently reasonable. However, for Complementary and A...

This paper addresses the property requirements of repair materials for high durability performance for concrete structure repair. It is proposed that the high tensile strain capacity of High Performance Fiber Reinforced Cementitious Composites (HPFRCC) makes such materials particularly suitable for repair applications, provided that the fresh properties are also adaptable to those required in p...

Introduction: Journal clubs play an important role in teaching Evidence Based Medicine (EBM). Evidence based journal clubs focus on real problems of the group, and set a minimum level of evidence for articles to be presented, and in the end a clinical bottom line is set to be used in the daily clinical practice. In this article, we have explained our experience in running evidence based journal...
