On the injectivity of C1 maps of the real plane

Let X : ℝ2 → ℝ2 be a C1 map. Denote by Spec(X) the set of (complex) eigenvalues of DXp when p varies in ℝ2. If there exists ε > 0 such that Spec(X) ∩ (-ε, ε) = ∅, then X is injective. Some applications of this result to the real Keller Jacobian conjecture are discussed.

Desempenho de um trator agrícola equipado com pneus radiais e diagonais com três níveis de lastros líquidos

A utilização correta de pneus em tratores, tanto em relação ao seu tipo quanto à calibração de sua pressão interna, e a lastragem ideal para cada condição de carga são fatores que influem significativamente no desempenho do trator. Esta pesquisa teve como objetivo comparar o desempenho de um trator equipado com pneus radiais e com pneus diagonais, para três condições de lastragem líquida (0%, 40% e 75% de água), em três condições superficiais de um Nitossolo Vermelho distrófico (superfície firme, preparada e com cobertura vegetal de resto de milho) e em três velocidades teóricas de deslocamento (4 km h-1, 5 km h-1 e 7 km h-1), informadas no painel do trator, correspondendo às marchas B1, B2 e C1. O melhor desempenho do trator, equipado com pneu diagonal, ocorreu na condição de 75% de água nos pneus, apresentando maior velocidade de deslocamento, menor patinhagem do trator, menor consumo horário de combustível e gerando maior potência na barra de tração. Com pneus radiais, o melhor desempenho do trator ocorreu na condição de 40% de água nos pneus, proporcionando maiores velocidades de deslocamento do trator, menores patinhagens, menores consumos, horário e específico de combustível, e maiores potência e rendimento na barra de tração.

Influence of the season of year, stage of lactation and milking time on the chloride content in bovine milk

From January to October 1995, chloride content determinations were accomplished in 2,218 samples of milk collected from 67 quarters of 17 lactating cows, in initial, middle and final stages of lactation, in the morning and afternoon milking. The highest means of chloride contents were observed among the milk samples collected in the final stage of lactation (0,203 gC1/100ml), in the summer (0,212 gC1/100ml) and in the morning milking (0,189 g C1/100ml). The differences observed between the chloride contents in the samples obtained in the different stages of lactation and the seasons of the year were statistically significant (P<0.0001). The gratest occornce of chloride at rates superior to 0.22 gC1100ml was observed in the final stge of lactation (31.4%), summer (44.2%) and after the morning milking (27.8%). These results evidentiate the influence of physiological and external factors (stage of lactation and season of the year) on the concentration of chloride of milk.

Phosphorus bioavailability in diets for growing horses

A study of phosphorus (P) metabolism was carried out using 12 month old Brasileiro de Hipismo breed of horses to determine the P bioavailability available from feeds commonly fed to horses in Brazil. Five different diets were formulated to contain approximately equivalent levels of crude protein and digestible energy, as well as to supply at least 22 g P/horse/day (NRC, 1989). All 5 diets contained 40% Bermuda coastal hay plus 60% concentrate. The 5 different concentrates contained: C1 (corn+ cottonseed meal) C2 (corn grain+soybean meal) C3 (corn+sugarcane yeast), C4 (oat+cottonseed meal), and C5 (oat+soybean meal). The radioisotope (32)p was injected with 30 NIB. Blood, feces and urine were collected for 7 days to evaluate endogenous fecal P and true absorption. Analysis of variance of P intake showed differences due to dietary effects (P < 0.05). Concentrate C3 had the lowest intake (79.68 mg/ kg BW). All of the diets produced positive P retention. Absolute values for P concentrations in plasma, urine, feces and endogenous feces did not vary between diets. Values for endogenous fecal P were independent of the level of P intake, so the correlation between P intake and P endogenous was not significant. P bioavailability values were 50.75; 40.98; 43.50; 51.03 and 57.68% for diets C1 through C5, respectively. However, differences in P bioavailability were found (P < 0.05) between diets. Diets C2 and C3 had lower P bioavailability than the other diets. The P bioavailability of all dietary treatments in this study exceeded NRC (1989) postulations of 35% true P absorption in diets not supplemented with inorganic P. The results of this study indicate that inorganic P supplementation is not needed for growing yearlings fed common Brazilian feeds. Considering the high cost of P supplementation and the risk of environmental P contamination, inorganic phosphorus supplementation for growing yearlings may not be required. (c) 2007 Elsevier B.V.

Desempenho de trator agrícola em três superfícies de solo e quatro velocidades de deslocamento

The aim of this work was to evaluate tractor performance in soil with three different surfaces: firm soil without covering, mobilized soil, and firm soil with vegetal residue of corn and braquiaria, for four forward speeds. The experiment was accomplished in three plots determined by the soil conditions. In each plot four treatments were composed by the forward speed obtained by the changes of the tractor gear. Six repetitions were used in each plot, totaling 72 experimental units, combination of the traction, slip of the rear and front wheels, forward speed and fuel consumption. The values of the tractor performance obtained led to the conclusion that in the firm soil without vegetable covering the tractor performance was better, followed by the soil with the firm surface and covered with corn straw and braquiaria and finally the mobilized soil. The best tractor performance was obtained in the C1 gear that supplied the forward speed of 6 km h(-1).

Resposta da alface à adubação nitrogenada com diferentes compostos orgânicos em dois ciclos sucessivos

Os objetivos deste trabalho foram avaliar a produção de alface em ambiente protegido, utilizando diferentes compostos orgânicos como fonte de nitrogênio, e seu efeito residual em dois ciclos sucessivos. O experimento foi conduzido entre os meses de fevereiro e maio de 2005, em casa-de-vegetação com ventilação e temperatura controlados, utilizando vasos de 3,5 L e solo classificado como Latossolo Vermelho Escuro. Foram utilizados compostos orgânicos produzidos a partir da mistura de resíduos do processamento de quatro plantas medicinais e esterco bovino. Os compostos C1, C2, C3 e C4 nas doses 30, 60, 90 e 120 t ha-1 constituíram os tratamentos dispostos em delineamento inteiramente casualizado, com quatro repetições e uma testemunha (adicional). Foram determinados: matéria fresca da parte aérea (MFPA); massa de matéria seca da parte aérea (MSPA). Os compostos aplicados supriram satisfatoriamente as necessidades de nitrogênio da cultura, no primeiro ciclo, dispensando o uso de fertilizante mineral. A composição dos materiais aplicados influenciou significativamente a produção de alface no primeiro ciclo, promovendo efeito residual no segundo ciclo, porém em menores proporções.
