EFEITO DA ADUBAÇÃO ORGÂNICA NA PRODUÇÃO DE BIOMASSA EM QUEBRA-PEDRA (Phyllanthus stipulatus, EUPHORBIACEAE) EM MANAUS, AMAZONAS, BRASIL

O quebra-pedra (Phyllanthus stipulatus (Raf.) Webster, Euphorbiaceae) é um importante remédio popular usado para reduzir o ácido urico no sangue e facilitar a eliminação de cálculos renais. Para avaliar a produção de biomassa dessa espécie utilizou-se sementes de populações naturais num experimento realizado em Manaus, AM. Adotou-se um delineamento experimental de parcelas subdivididas, onde as parcelas foram: (a) o ambiente natural e (b) o ambiente com tela plástica sombrite com 50% de luminosidade, e as subparcelas constituídas por dosagens de 0,2,4,6,8 e 10 kg de composto orgânico/ m2. Não foram encontradas diferenças significativas entre os ambientes na biomassa total das plantas (63,1 g vs 62,3 g fresca e 26,6 g vs 25,6 g seca), embora tivessem sido encontradas para a altura (70,0 cm a pleno sol vs 96,2 cm sombra) e, conseqüentemente, para a biomassa do caule (5,lg vs 5,7 g seca, respectivemente). O quebra-pedra responde bem a adubação orgânica, tanto na biomassa total, como em todas as partes da planta. A melhor resposta, em termos de rendimento, se deu sob o efeito de 10 kg de CO/m2 incorporado ao solo ( 1,26 kg/m2 de biomassa fresca e 0,55 kg/m2 de biomassa seca). Em comparação com a testemunha, este tratamento produziu 43% mais biomassa seca total. No entanto, a razão benefício/ custo sugere que 4 kg de CO/m2 é a quantidade máxima que é economicamente viável no solo usado. A biomassa total é composta de 17,2% de raízes, 22,3% de caules, 23,1% de galhos e 37,4% de folhas. O crescimento das plantas exige muito potássio e pouco fósforo, magnésio e micronutrientes.

Improving Stroke Services in Northern Ireland (PDF 194 KB)

Stroke can strike anyone, any age, anytime. Today in Northern Ireland around 4000 people each year have their lives and the lives of their families dramatically changed by stroke. A significant number of these could be avoided by simple lifestyle changes. More exercise, less alcohol and more attention to diet can make a major difference. Cutting down or cutting out smoking will make the most significant lifestyle contribution to a reduction in stroke and the enormous personal impact that it brings. åÊThese recommendations seek to make improvements in the key areas of prevention; treatment and rehabilitation of stroke patients in a modern health service setting. The accompanying standards outline the levels to which we must aspire, in the delivery of these services. åÊ

Mission-Oriented Dust Control and Surface Improvement Processes for Unpaved Roads, HR-194, 1981

Six subject areas prompted the broad field of inquiry of this mission-oriented dust control and surface improvement project for unpaved roads: • DUST--Hundreds of thousands of tons of dust are created annually by vehicles on Iowa's 70,000 miles of unpaved roads and streets. Such dust is often regarded as a nuisance by Iowa's highway engineers. • REGULATIONS--Establishment of "fugitive dust" regulations by the Iowa DEQ in 1971 has created debates, conferences, legal opinions, financial responsibilities, and limited compromises regarding "reasonable precaution" and "ordinary travel," both terms being undefined judgment factors. • THE PUBLIC--Increased awareness by the public that regulations regarding dust do in fact exist creates a discord of telephone calls, petitions, and increasing numbers of legal citations. Both engineers and politicians are frustrated into allowing either the courts or regulatory agencies to resolve what is basically a professional engineering responsibility. • COST--Economics seldom appear as a tenet of regulatory strategies, and in the case of "fugitive dust," four-way struggles often occur between the highway professions, political bodies, regulatory agencies, and the general public as to who is responsible, what can be done, how much it will cost, or why it wasn't done yesterday. • CONFUSION--The engineer lacks authority, and guidelines and specifications to design and construct a low-cost surf acing system are nebulous, i.e., construct something between the present crushed stone/gravel surface and a high-type pavement. • SOLUTION--The engineer must demonstrate that dust control and surface improvement may be engineered at a reasonable cost to the public, so that a higher degree of regulatory responsibility can be vested in engineering solutions.

SÍNTESE E CARACTERIZAÇÃO DE COMPÓSITOS ORGÂNICO-INORGÂNICOS MACROPOROSOS PARA O SENSORIAMENTO DE H2O2

Electrodes modified with poly(5-amino-1-naphthol)/Prussian blue (poly(5-NH2-1-NAP)/PB) hybrid films are able to electrochemically reduce H2O2 in medium containing an excess of Na+ cations. This is an important advantage for biosensing applications over electrodes in which only conventionally (electro) deposited Prussian blue is present. Consequently, the aim of this work was to examine the application of templates of ordered arrays of colloidal poly(styrene) spheres (800, 450 and 100 nm in diameter) to produce inverse opal structures of poly(5-NH2-1-NAP)/PB hybrid platforms, in an effort to study the influence of the increase in surface area/volume ratio and higher exposition of the mediator active sites on material performance during H2O2 determination employing the different sized porous structures. Moreover, since the accentuated hydrophilic character of poly(5-NH2-1-NAP)/PB also allows H2O2 electrochemical reduction in inner active sites, issues concerning the amount of mediator electrodeposited on the electrode were also reflected in the observed results.

USO DA RMN DE BAIXA RESOLUÇÃO NA AVALIAÇÃO DA DINÂMICA MOLECULAR DO Origanum vulgare

In this work, proton NMR relaxometry was used to measure the behavior of spin-lattice relaxation time with T1H as the time constant, and also of spin-spin relaxation time with the time constant T2H. These relaxometry parameters were determined to better understand the changes in the main structures present in commercial and in nature forms of origanum. The T1H relaxation data showed that the structures which had higher molecular mass were more sensitive to degradation with increased temperature treatment. According to the values of the T2H parameter, up to 150 degrees no significant change in the mobility and organization of water was observed. These data infer that the ideal cooking temperature and tea preparation mode for this herb should be around 100 degrees for the sample not to lose its characteristics. Also, it is not advisable to cook this herb at higher than 150 degrees but better to consume it at room temperature, especially give commercial herb has already been dehydrated.
