Plants live in complex environments in which they intimately interact with a broad range of microbial pathogens and insect herbivores with different lifestyles and infection or feeding strategies. The evolutionary arms race between plants and their attackers provided plants with a sophisticated defense system that, like the animal innate immune system, recognizes the attacker and responds by ac...

In this investigation, a sugarcane agroecosystem at a coastal tableland, in the northeast of Brazil, was screened to obtain bacteria strains able to synthesize poly-β-hydroxyalkanoates (PHA), using sucrose as the main carbon source. The potential to synthesize PHA was tested qualitatively by Sudan Black staining of colonies growing in different carbon sources: sucrose, glucose, fructose, propio...

The aim of this paper is to describe innovations taking place in national nutrition surveys in the UK and the challenges of undertaking innovations in such settings. National nutrition surveys must be representative of the overall population in characteristics such as socio-economic circumstances, age, sex and region. High response rates are critical. Dietary assessment innovations must therefo...

Remark: By the same reasoning, if one replaces 2016 in the problem by a general integer N, then the minimum value of j is the smallest one for which N divides j!. This can be deduced from Pólya’s observation that the set of integer-valued polynomials is the free Zmodule generated by the binomial polynomials (x n ) for n = 0,1, . . . . That statement can be extended to polynomials evaluated on a...

Development agencies are endeavouring to think and act more politically, but they typically overlook people’s politics in the process. This is true also of the scholars and consultants who advise on and advocate politicallyinformed programming.2 Despite there now being a range of approaches to politically-informed programming, overwhelmingly the political actors thought to matter are elites and...

The role of microsomal cytochrome b5 (Cyb5) in defining the rate of drug metabolism and disposition has been intensely debated for several decades. Recently we described mouse models involving the hepatic or global deletion of Cyb5, demonstrating its central role in in vivo drug disposition. We have now used the cytochrome b5 complete null (BCN) model to determine the role of Cyb5 in the metabo...

The fourteen kinds of pressure-transmitting media were evaluated by the ruby fluorescence method at room temperature, 77 K using the diamond anvil cell (DAC) up to 10 GPa in order to find appropriate media for use in low temperature physics. The investigated media are a 1:1 mixture by volume of Fluorinert FC-70 and FC-77, Daphne 7373 and 7474, NaCl, silicon oil (polydimethylsiloxane), Vaseline,...

We investigated the effect of PCB-77, -126 or -153 (10 or 100 ng/ml) on free intracellular calcium concentrations([Ca2+]i) in bovine myometrial cells from days 1-5 of the estrous cycle. Cells were incubated with or without PCBs for 48 h (38 degrees C, aerated atmosphere) and thereafter [Ca2+]i was measured by means of fluorescent calcium indicator Fura-2. PCBs increased basal concentrations of ...

77 THIS FEATURE PRESENTS A RELAtively unique concept for urban arterial highway interchanges. The interchange has been named the Echelon Interchange because of its symmetrical, but offset, pair of two-phase one-way pair intersections—one elevated over the other. An observer1 noted that the interchange resembled a flying formation used by the U.S. Navy Flight Demonstration Team, the “Blue Angels...
