Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "coast cross nº 1" e a análise física e química de um latossol vermelho amarelo: I. Concentrações de nutrientes nas folhas em função das frações granulométricas do solo

Foi realizado um levantamento em 41 áreas de um solo classificado como Latossol Vermelho Amarelo, com amostragens de solo e de folhas da forrageira "Coast Cross nº 1" objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises físicas do solo. Os autores observaram que a concentração de potássio nas folhas correlaciona-se negativamente com a fração silte do solo. A concentração de cobre nas folhas correlaciona-se negativamente com a fração areia fina e positivamente com argila. Ferro, manganês, zinco, sódio, boro e alumínio não apresentam correlações entre as suas concentrações foliares e os teores de argila no solo.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "Coast Cross nº 1" e a análise física e química de um Latossolo vermelho amarelo II: Concentração de nitrogênio e fósforo

Foi realizado um levantamento em 41 pontos de um Latossolo Vermelho Amarelo, com amostragem de solo e folhas da forrageira "Coast Cross Nº 1", objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises químicas do solo. As folhas foram secas e analisadas para N, P. As amostras de solo foram secas e analisadas pelos seguintes métodos: índices pH (água e CaCl2 0,01 M), matéria orgânica (digestão úmida) , P, K, B, Cu, Fe, Mn, Zn e Na pelo extrator de Mehlich. P através de resina iônica. Ca, Mg e Al pelo KC1 1 N. As frações granulométricas foram dispersas por NaOH 0,1 Ne separadas pelo método da pipeta. Foram observadas correlações entre as concentrações de elementos nas folhas e as determinações no solo. Nitrogênio nas folhas correlacionou-se negativamente com fósforo do solo e positivamente com manganês e enxofre. Fósforo nas folhas correlacionou-se negativamente com cálcio do solo.

Gastrite espontânea do camondongo e cogumelos do gênero Geotrichum Link

Slight acute catarrhal gastritis associated with fungi of the genus Geotrichum LINK was found to occur in apparently healthy white mice. This is of practical importance considering that the mouse is extensively employed in experimental work on nutrition.

A Methodology to measure shareholder value orientation and shareholder value creation aimed at providing a research basis to investigate the link between both magnitudes

Does shareholder value orientation lead to shareholder value creation? This article proposes methods to quantify both, shareholder value orientation and shareholder value creation. Through the application of these models it is possible to quantify both dimensions and examine statistically in how far shareholder value orientation explains shareholder value creation. The scoring model developed in this paper allows quantifying the orientation of managers towards the objective to maximize wealth of shareholders. The method evaluates information that comes from the companies and scores the value orientation in a scale from 0 to 10 points. Analytically the variable value orientation is operationalized expressing it as the general attitude of managers toward the objective of value creation, investment policy and behavior, flexibility and further eight value drivers. The value creation model works with market data such as stock prices and dividend payments. Both methods where applied to a sample of 38 blue chip companies: 32 firms belonged to the share index IBEX 35 on July 1st, 1999, one company represents the “new economy” listed in the Spanish New Market as per July 1st, 2001, and 5 European multinational groups formed part of the EuroStoxx 50 index also on July 1st, 2001. The research period comprised the financial years 1998, 1999, and 2000. A regression analysis showed that between 15.9% and 23.4% of shareholder value creation can be explained by shareholder value orientation.

The missing link in key sectors analysis

In general terms key sectors analysis aims at identifying the role, or impact, that the existence of a productive sector has in the economy. Quite a few measures, indicators and methodologies of varied complexity have been proposed in the literature, from multiplier sums to extraction methods, but not without debate about their properties and their information content. All of them, to our knowledge, focus exclusively on the interdependence effects that result from the input-output structure of the economy. By so doing the simple input-output approach misses critical links beyond the interindustry ones. A productive sector’s role is that of producing but also that of generating and distributing income among primary factors as a result of production. Thus when measuring a sector’s role, the income generating process cannot and should not be omitted if we want to better elucidate the sector’ economic role. A simple way to make the missing income link explicit is to use the SAM (Soci

Cross-infection experiments with "isospora" of cats and dogs

Feces of 34 dogs out of 251 (13.5%) from guanabara were positive for Isospora. From these 19 (7.5%) were i. rivolta, 13 (5.2%) were I. canis and 2 (0,7) were i. bigemina. "Free-sporocysts" of I. rivolta were eliminated by 9 dogs (3.5%). A "Caryospora-like" oocyst was seen once. Cross-infection experiments performed with Isospora from dogs and cats failed to produce infection while inoculations of these Isospora in their natural hosts succeeded. The results suggest that the species of Isospora occurring in cats are different from those of dogs.

Cross-suppression of specific immune responses after oral tolerance

Adult normal inbred mice rendered tolerant to OVA by previous oral exposure do not respond to intraperitonela immunization with DNP-OVA in adjuvant. These tolerant mice also form less DNP-specific antibodies to DNP-KLH when immunized with mixtures of DNP-KLH and DNP-OVA, or less HGG-specific antibodies when immunized with cross-linked conjugates of OVA and HGG. These same procedures increased DNP-specific or HGG-specific responses in non-tolerant control mice. The cross-supperssion was ineffective, however, to inhibit already ongoing antibody responses.
