The absolute perfection with which honeybees construct their hexagonal comb cells has astonished human beings since ancient times. deep mystery is not why hexagons, but how such a perfect geometrical shape fabricated, without any portrait or tools. Do they possess divine intelligence? Recent studies shed light on this revered and show beyond doubt that it the thermo-mechanical properties of bee...

The appropriateness of inotropic therapy in chronic heart failure was examined by critically reviewing five assumptions upon which this form of therapy has been justified. Only the first, that cardiac performance can be acutely improved by inotropic therapy, has been empirically proven. That such acute improvement is sustained appears to be true with non-catecholamine agents whereas the chronic...

Abstract We describe the case of a 25-year-old male who presented with bilateral patellar tendon rupture without any identified risk factors for injuries. Our patient is youngest adult reported to date confirmed bilateral, unprovoked, ruptures. accompany our an up-to-date literature review on this topic. A degree clinical suspicion required emergency room physicians as well orthopaedic surgeons...

Abstract In On Certainty , Wittgenstein conceives a novel way of dispelling skeptical doubts about our knowledge the external world. He acknowledges that in his attempt to refute skeptic, Moore uncovered epistemologically relevant propositions such as ‘I know this is hand’. But he denies appealing truisms likely succeed refuting skepticism–not because they cannot be doubted, but are not objects...

A procedure for preparation of semi-activated carbon fiber (SACF) without any treatment under high temperature was proposed. The first step of the procedure is coating of an inorganic fiber (E-glass fiber) by an adsorbent mixture including powder activated carbon, methyl cellulose and water. In this work a set of experiments was performed to attain appropriate adsorbent mixture for good quality...

Vast quantities of data are collected about us and our world: credit card transactions, movements and traffic flows, social networks, disease outbreaks, bird migrations, and flowers blossoming. These datasets span a wide range of public and private information and contexts. However, it is the emergence of a host of mobile phone based citizen sensing platforms that is poised to become the domina...
