Identificación de especies leñosas nativas promisorias para la restauración de la selva baja caducifolia del centro de Veracruz.
Provedor de dados: 32
Autores: Suárez Islas, Alfonso.
El objetivo de esta tesis fue identificar leñosas nativas de valor socioeconómico y ecológico para la restauración de la selva baja caducifolia de Paso de Ovejas, Veracruz. Se estudio: 1) el conocimiento local de las especies leñosas, a través de talleres y entrevistas y 2) el desempeño inicial de ocho de estas especies en un potrero degradado, plantadas en forma mixta así como en enriquecimiento. El estudio del conocimiento local arrojó un total de 76 especies citadas. Se analizaron los datos a través de índices de importancia cultural, percepción de escasez e importancia para fauna silvestre. Todas las especies mencionadas fueron útiles, las más importantes fueron fabáceas. Dos tercios del total se percibieron como escasas; el 70% fueron consideradas...

Evolution de communautés phytoplanctoniques après fertilisation modérée
Provedor de dados: 5
Autores: Jacques, G.; De Billy, G.
One approach to the problem of aquaculture consists in a simple acceleration of natural processes in extended areas of salt or brackish water. From this point of view, the authors have been in­terested in the effect of moderate fertilization on natural communi­ties . A first series of experiments (8) was made in an exter­nal tank of 3000 liters. After fertilization, the development of flowering diatoms was obtained each time. The time of latency, the level of production reached, the composition of the final communities is to some extent variable, but bacterial development may be neglec­ted. In contrast to earlier results, obtained in small volumes of water, these experiments have always led to simplified communities mostly dominated by the diatom...

Influência de fatores ambientais sobre o crescimento in vitro de Hypnea musciformis (Wulfen) Lamouroux (Rhodophyta)
Provedor de dados: 88
Autores: BRAVIN,ISOLDA C.; YONESHIGUE-VALENTIN,YOCIE.
Hypnea musciformis (Wulfen) Lamourox (Hypneaceae, Gigartinales) é uma fonte importante para o Brasil de um agente ficocolóide geleificante (carragenano) usado na indústria. O objetivo deste estudo foi o de investigar a influência da temperatura (20 e 25 ºC), do enriquecimento água do mar com a solução de Provasoli e aeração sobre o desenvolvimento desta espécie in vitro. Os talos de H. musciformis foram coletados na Prainha, Arraial do Cabo (RJ) em duas diferentes épocas do ano de 2000 (abril e julho). No laboratório, fragmentos apicais pesando 0,2 g (15 mm de comprimento) foram excisados do talo e preparados para as incubações em diferentes combinações de fatores. Em ordem decrescente, a análise de variância multifatorial mostrou que os fatores de maior...

Fatty acid profile of eggs of semi-heavy layers fed feeds containing linseed oil
Provedor de dados: 89
Autores: Souza,JG; Costa,FGP; Queiroga,RCRE; Silva,JHV; Schuler,ARP; Goulart,CC.
The incorporation of polyunsaturated fatty acids in chicken eggs by adding oils to the diets has been extensively studied. This experiment aimed at evaluating possible changes in the fatty acid profile of the eggs of layers fed diets supplemented with linseed and soybean oils. The experiment was performed using 192 29 week-old laying hens, distributed in a completely randomized design, into six treatments with four replicates of eight birds each. Treatments consisted of a control diet (no vegetable oil) and diets including 2% of vegetable oil. Linseed oil replaced 0, 25, 50, 75, and 100% soybean oil in the diets, corresponding to 0.0, 0.5, 1.0, 1.5, and 2.0% of linseed oil in the diet. A pool of two egg yolks from each treatment was submitted to lipid...

Response of the brain to enrichment
Provedor de dados: 42
Autores: DIAMOND,MARIAN C.
Before 1960, the brain was considered by scientists to be immutable, subject only to genetic control. In the early sixties, however, investigators were seriously speculating that environmental influences might be capable of altering brain structure. By 1964, two research laboratories proved that the morphology and chemistry or physiology of the brain could be experientially altered (Bennett et al. 1964, Hubel and Wiesel 1965). Since then, the capacity of the brain to respond to environmental input, specifically "enrichment,'' has become an accepted fact among neuroscientists, educators and others. In fact, the demonstration that environmental enrichment can modify structural components of the rat brain at any age altered prevailing presumptions about the...

Effect of Phosphorylation and Copper(II) or Iron(II) Ions Enrichment on Some Physicochemical Properties of Spelt Starch
Provedor de dados: 52
Autores: Rożnowski,Jacek; Fortuna,Teresa; Nowak,Katarzyna; Szuba,Edyta.
ABSTRACT: This paper provides an assessment of the effect of saturation of spelt starch and monostarch phosphate with copper or iron ions on selected physicochemical properties of the resulting modified starches. Native and modified spelt starch samples were analyzed for selected mineral element content using Atomic Absorption Spectroscopy (AAS). Thermodynamic properties were measured using DSC, and pasting properties by RVA. Flow curves of 5% pastes were plotted and described using the Herschel-Bulkley model. The structure recovery ratio was measured. AAS analysis established the presence of iron(II) and copper(II) ions in the samples of modified starches and that potassium and magnesium ions had leached from them. In comparison to unfortified samples,...

Provedor de dados: 55

Isolation and identification of etiological agents found in body fluids can be of critical importance for the recovery of patients suffering from potentially-severe infections, which are often followed by serious sequels. Eighty-two samples of different body fluids were analyzed using two different methods: (1) the conventional culture method (agar plating) and (2) the enrichment culture technique, using the Bact/Alert® blood culture bottle. The number of positive cultures increased on average from 9.7% to 23.1% with the enrichment culture technique. Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were the most frequently isolated bacteria. The enrichment method could provide a more accurate means the identifying etiological agents.
