Rainwater storage tank sizing: Case study of a commercial building

Constant and alternating temperature effects on germination and early growth of...

Scorzonera is a threatened species in Portugal. Given the role of temperature in germination and seedling recruitment, the performance of total germination, lag of germination, duration of germination, shape of germination, root and hypocotyl length, and relative root growth of scorzonera was investigated under constant and alternating temperatures between 10 and 25ºC. Because of scorzonera’s rarity and threate...

The implications of nitrogen on the fermentative growth extension of Saccharomy...

The peptone is used to provide nitrogen to Saccharomyces cerevisiae, which is an essential element for growth. In nature and in industrial musts, essential nutrients for yeast growth are available in complex and variable flux. Some of these compounds are herbicides, where some specific microorganisms are capable to mineralize or degrade into more basic and less harmful compounds to the environmental. The isopro...

Decline in glutathione peroxidase and cytoplasmic catalases by lindane may caus...

Lindane or gamma 1α,2α,3β,4α,5α,6β-hexachlorocyclohexane is an organochlorine insecticide, persistent in soils and aquifers, lipophilic, chemically and biochemically inert that accumulates along the human food chain. It is commonly used on a wide variety of crops, in warehouses, in public health to control insect-borne diseases, and (with fungicides) as a seed treatment. Lindane is also presently used in lotion...

Deficiências minerais em Scorzonera hispanica. Sintomas e efeitos no crescimento

A escorcioneira (Scorzonera hispanica L.), de ocorrência espontânea na Península Ibérica, é cultivada pela sua raiz tuberosa. Com o objectivo de tipificar sintomas de deficiências minerais em escorcioneira cultivaram-se plântulas em diferentes soluções nutritivas durante 15 dias, estudando-se o crescimento e produção de biomassa aérea e radicular. Uma solução nutritiva completa serviu de referência, consistindo...

Pisolithus arhizus (Scop.) Rauschert improves growth of adventitious roots and ...

Stone pine (Pinus pinea L.) is an economically important forest tree in the Mediterranean region and has been the target of breeding and selection through micropropagation mainly for its ecological and ornamental aspects. A crucial step in micropropagation is adventitious rooting of microshoots, which often is highly inefficient in most conifer species including stone pine. Hence, we conducted in vitro co-cultu...

Integer-valued self-exciting threshold autoregressive processes

In this article, we introduce a class of self-exciting threshold integer-valued autoregressive models driven by independent Poisson-distributed random variables. Basic probabilistic and statistical properties of this class of models are discussed. Moreover, parameter estimation is also addressed. Specifically, the methods of estimation under analysis are the least squares-type and likelihood-based ones. Their p...

Antioxidant power of Malus domestica juice partially reverses the oxidative eff...

Apple juices are described as potential inhibitors of oxidative stress preventing chronic disorders such as cancer and cardiovascular disease. Accordingly, the main intention of this study was to evaluate the influence of Golden Delicious apple juice, from Beira Alta, Portugal on cell proliferation of S. cerevisiae UE-ME3 exposed to oxidant, vanadium pentoxide. The results show that 2.0 mM vanadium pentoxide i...
