Do short range correlations inhibit the appearance of the nuclear pasta?
It is well known that strongly correlated neutron-proton pairs, the
short-range correlations (SRC), can modify many of the nuclear properties. In
this work we have introduced, for the first time, short range correlations in
the calculation of the nuclear pasta phase at zero temperature and checked how
they affect its size and internal structure. We have used two different
parameterizations of relativistic models in a mean field approximation and the
coexistence phase approximation as a first estimation of the effects. We have
seen that for very asymmetric neutron-proton-electon matter, the pasta phase
shrinks considerably as compared with the results without SRC and all internal
structures vanish, except the simple spherically symmetric one, the droplets.
Our results indicate a possible disappearance of these complicated structures
as the temperature increases.Comment: 4 pages, 4 figure

Performance of Beef Cattle Fed Diets Containing \u3cem\u3eStylosanthes\u3c/em\u3e and Corn Silages
Reports of the use of tropical legumes in silage production are scarce as these legumes have high contents of crude protein, low water soluble carbohydrate and high buffering capacity, which inhibit the production of silages with good fermentation and nutritional characteristics. Recent research has, however, shown that it is possible to produce good quality silages using tropical legumes (Pereira et al. 2012). Souza et al. (2012) concluded that silage produced from Stylosanthes cv. Campo Grande (Stylosanthes capitata + Stylosanthes macrocephala) at 60% proportion of the dry matter of the diet can replace corn silage in diets for beef cattle in feedlots without altering their intake and productive performance. However, the ideal proportion of this silage in the diets for beef cattle is still unknown. Thus, the objective of this study was to evaluate the intake and performance of beef cattle fed diets with Stylosanthes and corn silages
Microbial population, fermentative characteristics and dry matter recovery of mixed silage grass xaraés and stylo Campo Grande
The population of microorganisms, the fermentative characteristics and the recovery of dry matter of silage of xaraés grass (Brachiaria brizantha) with growing levels of Styansanthes capitata x S. macrocephala (0; 25; 50; 75) and 100%), with and without microbial inoculant. The 5 x 2 factorial scheme (five proportions of Campo Grande stylos with and without inoculant) was used in the completely randomized design, with three replications. There was no effect of the interaction of levels of stylos and microbial inoculant for the studied variables, however, it was observed effect of stylos levels on pH and ammoniacal nitrogen and inoculant on dry matter recovery. The mean population of lactic acid bacteria in the silages was 6.8 log cfu/g. The values of pH and ammoniacal nitrogen decreased linearly with the increase of the stylos levels in the silage. Mean dry matter recovery was 94%. It is concluded that the use of legume together with grass for silage production improves the fermentation characteristics and provides high recovery of dry matter, however, the inoculant evaluated does not alter the fermentative characteristics of the silages
