Editor-Chefe do JBP Jornal Brasileiro de Pneumologia, Brasília (DF) Brasil. The Portuguese word momento can be translated in a number of ways. It is first and foremost translated as “moment”, which has an eminently temporal connotation, indicatin...

We analyze a variant of the coupon collector’s problem, in which the probabilities of obtaining coupons and the numbers of coupons in a collection may be non-uniform. We obtain a finite expression for the generating function of the probabilities to complete a collection and show how this generalizes several previous results about the coupon collector’s problem. Also, we provide applications abo...

Italian soldiers carrying their skis marching up snow-covered mountain trails. Some of the most ferocious mountain warfare to date occurred during World War I between Italian and Austrian armies, far outstripping mountain battles in other wars. This photograph was taken in April, when the snow had been softened by the warmer rays of the sun and the path made almost impassable by the slush. The ...

BACKGROUND The performance in master marathoners has been investigated in flat city marathons but not in mountain marathons. This study examined changes in the sex differences in performance across time in female and male master runners competing in a mountain marathon compared to a flat city marathon. METHODS The association between age and performance of finishers in the Jungfrau Marathon, ...

Panax ginseng is the most widely used herbal medicine for improving cognitive functions. The pharmacological activity and underlying mechanisms of mountain-cultivated ginseng, however, have yet to be clearly elucidated, in particular, against trimethyltin-induced cognitive dysfunction. We previously reported that interleukin-6 plays a protective role against trimethyltin-induced cognitive dysfu...

Effects of landfall location and approach angle on track deflection associated with a tropical cyclone (TC) passing over an idealized and Central Appalachian Mountain is investigated by a series of idealized numerical experiments. When the TC landfalls on the central portion of the mountain range, it is deflected to the south upstream, passes over the mountain anticyclonically, and then moves w...

The age of the best marathon performance has been well investigated for flat city marathon running, but not for mountain marathon running. The aim of this study was to determine the age of the best mountain marathon performance and to compare to results of a flat city marathon. Race times and ages of finishers of a mountain marathon with 1,830 m of altitude change (Jungfrau Marathon, Switzerlan...

abstract due to calcareous soil conditions, zinc deficiency is a yield limiting factor for wheat production in iran. one solution for this problem is the cultivation of zn-efficient wheat varieties. ten wheat cultivars (nine bread wheat and one durum wheat) with different tolerance to zn deficiency were studied in a greenhouse experiment. plants were treated with zn (10 mg zn kg-1 soil as znso4...

in order to study on adaptability and grain yield stability of eight bread wheat cultivars (alvand, alamout, zarrin, navid, azar 2, sabalan, omid and bezostiya), a rcbd experiment was conducted during three cropping seasons (2007-2010) at six locations (sanandaj, gorveh, marivan, divandarreh, saggez and baneh). simple analysis of variance (anova) and combined anova for three years in each locat...
