The exact solutions for the Navier–Stokes–Fourier equations in the case of plane shock waves for dilute monatomic gases with constant transport coefficients were found by Becker in 1922. The solutions obtained are limited for a Prandtl's number given by Pr=3/4$Pr=3/4$. Besides the solutions for the speed and temperature, profiles were given in an implicit way. In this paper, we consider Becker's model to find some exact explicit solutions for dilute polyatomic gases. [ABSTRACT FROM AUTHOR]

This paper considers the exact solutions for plane shock waves in dilute polyatomic gases. The local enthalpy in the steady state plays an important role and fixes the Prandtl's number to write the temperature profile in an exact way. The condition for the Prandtl's number is a generalisation of Becker's result and now it considers the bulk viscosity. The velocity profile can also be found in an exact implicit way when the viscosity index is an arbitrary positive number. [ABSTRACT FROM AUTHOR]

The in vitro and in situ dry matter digestibility (IVDMD and ISDMD) of a silage elaborated from ground integral sugarcane (GISC) plus 40 % of fresh pig manure (FPM) enriched with VITAFERT, and the effect of replacing corn silage with GISC-FPM silage on the production of milk and ruminal methane (CH44, were evaluated. The study was conducted at the University of Caldas –Colombia– in a tropical dairy production system. The IVDMD and ISDMD were each evaluated through completely randomized designs, with eight degradation times. To study the milk production 18 F1 (Zebu x Holstein) cows were used, between the second and eighth lactation, which grazed star grass (Cynodon plectostachyus) and received 5 kg/animal/day of corn silage. Nine cows, considered control, received corn silage and nine were fed GISC-FPM silage. The CH4 measurements were conducted on four cows of each treatment. The digestibility of both silages, at 72 hours, reached values higher than 70 %. There were no significant differences in the milk production and silage intake, and no alterations were observed in the sanitary status of the animals. The cows fed GISC-FPM silage produced, significantly, less ruminal CH4. The digestibility of the silages at 72 h was similar to that of the balanced feedstuffs, which proved the possibility of a partial substitution. There was modulating effect of the GISC-FPM silage, because less ruminal CH4 was produced (6,9 ppm) than with the corn silage (7,6 ppm). It is concluded that the inclusion of pig manure enriched with VITAFERT in the sugarcane silages can be an alternative in animal feeding. [ABSTRACT FROM AUTHOR]

A 4.5-mm filarial worm was removed from the anterior chamber of the left eye of a 56-year-old man who had lost the sight in the right eye due to trauma some years earlier. The worm was removed intact through an upper scleral incision with a corneal based flap. Within 2 months vision was normal. The worm was identified as a sexually mature male of an undescribed species of Loaina Eberhard and Orihel 1984, a genus related to Loa and Dirofilaria.
