Twenty-Five years ago the surgical world in England, as I remember it, was largely dominated by a small circle of London Surgeons, of whom Sir Frederic Treves might fairly be considered the chief. It was a school with a short way with dissenters, and no doubt had its little mannerisms. The instrument known as a director (a harmless tool if properly employed, and still in common use in spite of ...

The aetiology of this ' universal and distressing complaint' which is very common in India is variable and need not be discussed in detail, though heredity, constipation, sedentary habits, child-bearing, middle age and drastic methods of cleaning the anus are all important factors, while in later life carcinoma of the rectum and enlarged prostate must never be forgotten. On looking at a patient...

Hydrogels can promote desirable cellular phenotype by mimicking tissue-like stiffness or serving as a gene delivery depot. However, nonviral gene delivery inside three-dimensional (3D) hydrogels remains a great challenge, and increasing hydrogel stiffness generally results in further decrease in gene delivery efficiency. Here we report a method to enhance nonviral gene delivery efficiency insid...

We propose a variation of Wythoff’s game on three piles of tokens, in the sense that the losing positions can be derived from the Tribonacci word instead of the Fibonacci word for the two piles game. Thanks to the corresponding exotic numeration system built on the Tribonacci sequence, deciding whether a game position is losing or not can be computed in polynomial time.

In ano-rectal disorders, incidences of piles and fissures are increasing in Indian population due to the western lifestyle. In surgery many methods are available for curing ano-rectal disorders but nowadays demand of Ayurveda and herbal preparation are increasing in society.

Sacrificial dilemmas, especially trolley problems, have rapidly become the most recognizable scientific exemplars of moral situations; they are now a familiar part of the psychological literature and are featured prominently in textbooks and the popular press. We are concerned that studies of sacrif icial dilemmas may lack experimental, mundane, and psychological realism and therefore suffer fr...

Deep foundations are increasingly being used, not just to carry structural loads, but also to act as heat exchangers as part of a ground source heat pump system. Such foundations, often called energy piles, have the potential to make significant contributions towards meeting the heating and cooling demands of buildings, thus reducing the overall energy consumption and carbon dioxide emissions d...

In “Bulgarian Solitaire”, a player divides a deck of n cards into piles. Each move consists of taking a card from each pile to form a single new pile. One is concerned only with how many piles there are of each size. Starting from any division into piles, one always reaches some cycle of partitions of n. Brandt proved that for n = 1+2+ · · ·+k, the cycle is just the single partition into piles ...

driven precast reinforced concrete piles (dprcp) is extensively used as a foundation for bridges constructed over canals in egypt in order to avoid the diversion of water canals. the objectives of this research include identifying the main activities of dprcp execution in the bridge-construction industry in egypt and the risk factors affecting them. in addition, assessment of the effects of the...
