A method for computing the closure of a set of attributes according to a specification of Functional Dependencies of the relational model is shown. The main feature of this method is that it computes the closure using solely the inference system of the SLFD logic. For the first time, FD Logic is used in the design of automated deduction methods to solve the closure problem. The strong link betw...

The Vacuum-assisted Closure device decreases the time to wound healing, thus increasing the deposition of granulation tissue, and decreasing the use of wound care specialists. Perineal wounds present a special challenge. We present four cases of complex perineal wounds in which the Vacuum-assisted Closure device was used. In each case, wound care was simplified and healing accelerated. The Vacu...

Background Few studies perform follow ups on patent ductus arteriosus (PDA) patients who undergo transcatheter closure. In addition to side effects from the procedure, it is important evaluate changes in left ventricular function (LVF) parameters and nutritional status.
 Objective To compare LVF status before during one-year period post-transcatheter PDA closure, potential associated facto...

1. The pinnae of sensitive brier or Schrankia are favorable for demonstrating summation of dissimilar stimuli. 2. The demonstration was made as follows: A time of day was chosen when the closure of a single proximal leaflet did not provoke closure of the next distal leaflet. An irritating gas was applied to the pinna. A few seconds later, a single leaflet was touched; it closed, induced closure...

We deene the notion of weak relative pseudo-complement, and we show that, for an arbitrary lattice, the property of weak relative pseudo-complementation is strictly weaker than relative pseudo-complementation, but stronger than pseudo-complementation. Our main interest for this notion is in relation with the theory of closure operators. We prove that if a complete lattice L is completely inf-di...

Closure of massive abdominal wounds can be a challenging surgical problem. Presented here is a novel technique for reconstitution of the abdominal wall after severe internal injuries complicated by sepsis required a prolonged period of open abdominal dressing changes. By using an innovative and effective progressive tension band system, the fascial edges could be reapproximated over time allowi...

Intramolecular [2+2] photocycloaddition of aromatic chain imides possessing bis-phenanthrene moieties afforded straight and cross ring closure products. The ratio of cycloadducts was dependent on reaction time and temperature, which resulted in a reversal of regioselectivity. The reaction was proved to involve a retro cycloaddition. The cross ring closure products were formed predominantly in t...

T he optimal secondary prevention strategy in patients presenting with a cryptogenic stroke or transient ischemic attack (TIA) and a patent foramen ovale (PFO) is uncertain. In the United States, closure of a PFO using a percutaneous transcatheter device is currently considered investigational by the Food and Drug Administration. Nonetheless, many patients in this setting are treated off-label ...

Two experiments investigated the tendency of groups with members under high (vs. low) need for cognitive closure to develop an autocratic leadership structure in which some members dominate the discussion, constitute the "hubs" of communication, and influence the group more than other members. The first experiment found that high (vs. low) need for closure groups, as assessed via dispositional ...

Temporal logic can be used to describe processes: their behaviour is characterized by a set of temporal models axiomatized by a temporal theory. Two types of models are most often used for this purpose: linear and branching time models. In this paper a third approach, based on socalled joint closure models, is studied using models which incorporate all possible behaviour in one model. Relations...
