Using standard group theoretical techniques we construct the exact wave function of the $[{\bf 70},1^-]$ multiplet in the orbital, spin and flavor space. This symmetric wave function is compared to that customarily used in the $1/N_c$ expansion, which is asymmetric. The comparison is made by analyzing the matrix elements of various operators entering the mass formula. These matrix elements are calculated by the help of isoscalar factors of the permutation group, specially derived for this purpose as a function of $N_c$. We also compare two distinct methods used in the study of the $[{\bf 70},1^-]$ multiplet. In the first method the generators are divided into two parts, one part acting on a subsystem of $N_c-1$ quarks called core and another on the separated quark. In the second method the system is treated as a whole. We show that the latter is simpler and allows to clearly reveal the physically important operators in the mass formula. [less ▲]

Analysis of passive microwave brightness temperatures from the space-borne Special Sensor Microwave Imager (SSM/I) documents a record surface snowmelt over high elevations (above 2000 m) of the Greenland ice sheet during summer of 2007. To interpret this record, results from the SSM/I are examined in conjunction with fields from the National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis and output from a regional climate model. The record surface melt reflects unusually warm conditions, seen in positive summertime anomalies of surface air temperatures, downwelling longwave radiation, 1000–500 hPa atmospheric thickness, and the net surface energy flux, linked in turn to southerly airflow over the ice sheet. Low snow accumulation may have contributed to the record through promoting anomalously low surface albedo. [less ▲]

Seed dispersal has a profound influence on structure and diversity in tropical environment. Although all frugivorous primates disperse seeds, the contribution of dispersal by some species in forest regeneration is still discussed. For instance, baboons and macaques are controversially described as seed dispersers or as seed predators. We study the seed dispersal by a troop of pigtail macaques (Macaca nemestrina leonina) in the Khao Yai National Park (Thailand) in order to describe the mode of seed dispersal and the seed fate of each fruit species consumed by macaques, including the assessment of potential germination enhancement for dispersed seeds. Pigtail macaques disperse seeds either via feces, by swallowing seeds, or via cheekpouch storage, by spitting out seeds after processing the fruits in the mouth. Preliminary results of our study show that pigtail macaques in the study troop disperse the seeds of at least 15 fruits species. For some species (Nephelium melliferum, Baccaurea ramiflora), macaques use the 2 modes of seed dispersal simultaneously. If part of the seeds excreted are intact and viable, as shown by the cut test, some are destroyed during mastication and digestion, and therefore it seems that macaques are to be considered both as seed dispersers and predators. The size of dispersed seeds ranges from the largest defecated seed (Nephelium melliferum) of 22mm long and 13mm wide to the smallest (Dissocheta divaricata) less than 1mm long and 0.5mm wide. In the future, Tetrazolium test will also be used to assess seed viability, and the germination enhancement for seeds defecated or spat out will be assessed using germination test. Germination rate and germination delay will be compared for defecated, spat and control (seeds from non consumed fruits collected from trees foraged by the macaques) seeds. [less ▲]

VP22, encoded by theUL49gene of Marek’s disease virus (MDV), is indispensable for virus cell-to-cell spreading. We show herein that MDVUL49can be functionally replaced with avian and human viral orthologs. Replacement of MDV VP22 with that of avian gallid herpesvirus 3 or herpesvirus of turkey, whose residue identity with MDV is close to 60%, resulted in 73 and 131% changes in viral spreading, respectively. In contrast, VP22 replacement with human herpes simplex virus type 1 resulted in 14% plaque formation. Therefore, heterologous avian and human VP22 proteins share sufficient structural homology to support MDV cell-to-cell spreading, albeit with different efficiencies. [less ▲]

Gliomas are the most common CNS tumours in children and present either as circumscribed tumours or diffusely infiltrative neoplasms. Diffuse gliomas develop both in the cerebral hemispheres and the brainstem and have a poor prognosis. Guidelines for the therapy of these tumours are still debated. In this study, we reviewed the clinical features of 27 consecutive patients with diffuse gliomas admitted to the Department of Paediatrics of CHR Citadelle, University of Liege, between 1985 and 2005. We review their clinical presentation, diagnosis, treatment and outcome with reference to the published literature. [less ▲]

When philosophers deal with the issue of the difference between human and animal beings, there is always a double ‘‘we’’ that imposes itself: ‘‘we’’ know that ‘‘we’’ are different. In order to resist these ‘‘we’s’’ the author has explored certain situations in which human and animals work together, and more extensively the everyday practices of cow and pig breeders. Interviewing the breeders, however, highlights an important issue: might the question of ‘‘the’’ difference, as philosophers have outlined it, be of interest to those who work with animals? Letting them construct ‘‘their’’ questions, we learn that these practices are best described in terms of achievement. Therefore, the questions that breeders think should be addressed are not the differences between human and non-human beings but rather the differences between situations, which offer both humans and animals different opportunities to accomplish subjectivities.

The present study was carried out on 19 stress negative Piétrain pigs (Pietrain ReHal), consisting of 13 gilts and 6 young boars imported from Belgium, raised in the livestock farm of Dong Hiep (Hai Phong) in order to evaluate growth performances and their adaptability in the North of Vietnam. Results showed that the average body weight of the whole herd at 2, 4, 5.5, and 8.5 months old was 19.05, 51.05, 85.82, and 119.47 kg, respectively. During the growing periods, except the first stage, the male grew faster than the female and the pigs of the CT genotype grew faster than those of CC genotype although the difference was not significant (P>0.05). The average daily gain (ADG) was 528.56 grams for the whole herd. The ADG was higher for the male (546.48 grams) than for the female (520.29 grams), and its was higher for the CT than the CC, but the difference was not statistically significant (P>0.05). The feed conversion ratio (FCR) was 2.69 kg. The estimated lean percentage at 8.5 months old was 64.08%. The results indicate that Piétrain stress negative pigs could develop well on the farm conditions in Hai Phong, Vietnam. [less ▲]
