introduction fishing is a leisure activity for some people around the world. accidently the fish hook can get hooked in the hand. if the hook is barbed, removal becomes difficult. we report a case of such a injury in the hand and discuss the technique for its removal with a brief review of the literature. case presentation a thirty-two year old male accidently suffered a fishhook injury to his ...

This comment on Paul Dolan's essay, 'Developing methods that really do value the "Q" in the QALY,' seconds his critique of current preference-based methods of valuing health states but disputes both his assumption that health states should be appraised by their bearing on well-being and his conclusion that the bearing of health states on well-being should be measured in terms of subjective expe...

Proper consistency is defined by the properties that each player takes all opponent strategies into account (is cautious) and deems one opponent strategy to be infinitely more likely than another if the opponent prefers the one to the other (respects preferences). When there is common certain belief of proper consistency, a most preferred strategy is properly rationalizable. Any strategy used w...

In a graph G = (V, E) provided with a linear order ”<” on V , a chordless path with vertices a, b, c, d and edges ab, bc, cd is called an obstruction if both a < b and d < c hold. Chvátal [2] defined the class of perfectly orderable graphs (i.e., graphs possessing an acyclic orientation of the edges such that no obstruction is induced) and proved that they are perfect. We introduce here the cla...

abstract: today, informal settlements have been accepted in the cities and towns as a problem and an urban fact facing urban and regional management in different countries of the world. according to past experiences and the evolutions of today, searching for new and efficient solutions in order to improve the quality of these settlements in line with converting them into a habitable zone of urb...

The aim of this paper is to generalize the‎ ‎notion of almost valuation domains to arbitrary commutative‎ ‎rings‎. ‎Also‎, ‎we consider relations between almost valuation rings ‎and pseudo-almost valuation rings‎. ‎We prove that the class of‎ ‎almost valuation rings is properly contained in the class of‎ ‎pseudo-almost valuation rings‎. ‎Among the properties of almost‎ ‎valuation rings‎, ‎we sh...

instrument fracture within the root canal during root canal treatment is an unwanted and frustrating complication. the fractured segment may hinder cleaning and shaping procedures with potential impact on prognosis of treatment. fracture of endodontic instrument often results from incorrect use or overuse. if breakage occurs clinically, the patient should be informed of the incident and conside...

We define very proper intersections of modules and projective subschemes. It turns out that equidimensional locally Cohen-Macaulay modules intersect very properly if and only if they intersect properly. We prove a Bezout theorem for modules which meet very properly. Furthermore, we show for equidimensional subschemes X and Y : If they intersect properly in an arithmetically Cohen-Macaulay subsc...
