forty-five patients with chronic obstructive pulmonary disease were studied to compare the acute effects of ipratropium bromide (60 µg), salbutamol (300 µg) and placebo (3 puffs) on the forced expiratory volume in 1 sec (fev 1) and forced vital capacity (pvc). ipratropium bromide produced a significantly greater improvement than salbutamol in both fev1 and fvc at 15,60 and 180 minutes after dru...

The order of discovery can have a profound effect upon the way in which we think about the function of a gene. In E. coli, recA is nearly essential for cell survival in the presence of DNA damage. However, recA was originally identified, as a gene required to obtain recombinant DNA molecules in conjugating bacteria. As a result, it has been frequently assumed that recA promotes the survival of ...

In order to reduce port pollution and carbon emissions improve the utilization rate of clean energy, a microgrid based on we-energies (WEs) its polymorphic distributed low-carbon energy management method is proposed. First, this study considers variety heterogeneous Wes, such as ship (SWEs), establish system for microgrids achieve reliable information exchange between WEs under different commun...

The one-dimensional shallow water equations (SWEs), coupled with bed load (Exner equation) were solved in this paper for the numerical simulation of sediment transport problem. By using an efficient meshless method based on radial basis function (RBF) that approximates unknown variables a set collocation nodes and Runge–Kutta fourth-order scheme to approximate temporal derivative. Besides, arti...

College students, especially women, demonstrated negativity toward math and science relative to arts and language on implicit measures. Group membership (being female), group identity (self female), and gender stereotypes (math male) were related to attitudes and identification with mathematics. Stronger implicit math male stereotypes corresponded with more negative implicit and explicit math a...

OBJECTIVE Nightmares are a robust and modifiable predictor of increased suicidality and poor psychiatric outcomes, yet nightmare screening and treatment remain rare, even in sleep centers. This paper aims to examine what proportion of nightmare sufferers have discussed nightmares with a healthcare provider, as well as possible explanations for low rates of nightmare complaints. METHODS The pr...

But the Lord came down to see. .. the tower which the sons of men had built. And the Lord said, ''Indeed the people are one and they all have one language, and this is what they begin to do;. .. Come, let Us go down and there confuse their language, that they may not understand one another's speech.''. .. Therefore its name is called Babel, because there the Lord confused the language of all th...

When not performing a task, we are usually engaged in a variety of thoughts, for instance about current problems, opportunities, our self-image, our relationships, about past experiences, and about plans for the future. Such mind wandering was found to occupy almost half of our time spent awake (Killingsworth and Gilbert, 2010). Mind wandering may have had the evolutionary advantage of better a...
