This article presents a new interpretation of the temple M's content placed in the so-called sanctuary of Asklepios in Emporion. The sculptures are related to an inscription of the area and also to a sigilado glass and chandeliers that come from the Roman city. All this proves the presence of an Egyptian worship in Emporion more complex than earlier. [less ▲]

Since the first works on thixoforming, lot of studies have been performed all over the world and the behaviour of the globular semi-solid slurry is now quite well understood. This knowledge had lead to an industrialisation of the technology for low melting point alloys as aluminium or magnesium. For high melting point alloys as steel, this industrialisation is still a wish but seems closer each year. In the aim of this development of the process, it is important to be able to accurately represent the behaviour of the slurry during thixoforming. In this goal, lot of constitutive models has been proposed during the last years. However, until now there isn’t any study about the friction in the case of thixoforming. This knowledge is needed as friction has an important effect on the flow of the slurry during the shaping. The aim of this work is so to propose a quantification of the friction coefficients for the thixoforming technology thanks to experiments on a dedicated tool and comparison with simulations run on the finite elements code Forge2008©. The friction law is a Coulomb limited Tresca one. [less ▲]

Current human activities can be responsible either of the loss or promotion of biodiversity at the regional scale. The study of the influence of human activities on patterns of biological diversity is therefore of primary importance in order to set up conservation strategies. We studied the influence of human activities on calcareous grassland floristic diversity in Belgium. During the past century, a high fragmentation of this habitat occurred within the study region. There was a delay between the process of fragmentation and the subsequent response in terms of species richness, which created an “extinction debt” in remnant calcareous grasslands. Although fragmentation was the main process involved, we also showed that some new habitat patches were created thanks to human activities during this period. These new habitat patches exhibited a species richness and composition that was found similar to old habitat patches. In the face of fragmentation, restoration programs were launched in the study region. Restored areas exhibited similar soil conditions as compared to reference grasslands. Plant species communities found in the oldest restorations tend to resemble reference grassland communities. However, some differences in species composition persisted after 15 years. It was also shown that some species did not colonize restored sites at all. With this respect, seed and germination microsite availability could be limiting factors for the colonization of restored sites. However, the absence or the lower colonization in restored areas compared to reference grasslands following seed addition and disturbance suggested that habitat quality could be considered as lower in restored habitats. Our results suggest therefore that restoration effort should be maintain in the study site. This effort is not vain as many species are able to colonize newly created sites. Finally, another threat to calcareous grasslands was studied i.e. the naturalization of the ornamental species Cotoneaster horizontalis. The analysis revealed that, although being at an early stage of naturalization, the species had an impact on vegetation structure and composition and on grassland diversity. Trade limitation for this species should be promoted in addition to management. [less ▲]

In orchards, the fruit production is currently oriented to integrated pest management. In order to develop efficient pest control strategy by using entomophagous beneficial and lowering the application of pesticides, sufficient knowledge of entomological populations is needed. Here, a systematic monitoring of insect diversity and abundance in a conservatory orchard of Gembloux was performed. Combining yellow traps and visual observations, 19 pest and 34 beneficial families were identified among the 10766 and 3985 insects caught in yellow traps and visual observations respectively. Calculation of diversity indices allowed us to demonstrate the variability according to fruit tree species and insects observation method. Highest insects diversity was registered in apple, then in cherry and finally in the apple-pear association and plum. Pests and beneficials represented 27% and 39% of the insect collections respectively. Aphids represented from 81% to 95%of pests depending on fruit tree species and observation method. The predominant specie was Brachycaudus helychrysi (Kaltenbach). Aphidophagous guild was largely present and mainly constituted by coccinellids and hoverflies. Harmonia axyridis Pallas and Episyrphus balteatus De Geer were the most abundant. Aphididae was found to be the most common orchard pests with a range of related aphidophagous beneficials. These results highlight the need leading to potential reasoning. [less ▲]

We review a recently proposed approach to study the lowest negative parity baryons within the $1/N_c$ expansion. The method is based on the derivation of the matrix elements of SU(2N$_f$) generators for mixed symmetric $[N_c-1,1]$ flavor-spin states. Presently it is applied to the N = 1 band and a comparison is made with a former method based on the decoupling of the system into a symmetric core of $N_c-1$ quarks and an excited one. We prove that the decoupling is not necessary and moreover, it misses some important physical consequences. [less ▲]

Recent studies have suggested that coinfusion of mesenchymal stem cells (MSCs) the day of hematopoietic cell transplantation (HCT) might promote engraftment and prevent graft-versus-host disease (GVHD) after myeloablative allogeneic HCT. This prompted us to investigate in a pilot study whether MSC infusion before HCT could allow nonmyeloablative (NMA) HCT (a transplant strategy based nearly exclusively on graft-versus-tumor effects for tumor eradication) from HLA-mismatched donors to be performed safely. Twenty patients with hematologic malignancies were given MSCs from third party unrelated donors 30-120 minutes before peripheral blood stem cells (PBSCs) from HLA-mismatched unrelated donors, after conditioning with 2 Gy total body irradiation (TBI) and fludarabine. The primary endpoint was safety, defined as a 100-day incidence of nonrelapse mortality (NRM) <35%. One patient had primary graft rejection, whereas the remaining 19 patients had sustained engraftment. The 100-day cumulative incidence of grade II-IV acute GVHD (aGVHD) was 35%, whereas 65% of the patients experienced moderate/severe chronic GVHD (cGVHD). One-year NRM (10%), relapse (30%), overall survival (OS) (80%) and progression-free survival (PFS) (60%), and 1-year incidence of death from GVHD or infection with GVHD (10%) were encouraging. These figures compare favorably with those observed in a historic group of 16 patients given HLA-mismatched PBSCs (but no MSCs) after NMA conditioning, which had a 1-year incidence of NRM of 37% (P = .02), a 1-year incidence of relapse of 25% (NS), a 1-year OS and PFS of 44% (P = .02), and 38% (P = .1), respectively, and a 1-year rate of death from GVHD or infection with GVHD of 31% (P = .04). In conclusion, our data suggest that HLA-mismatched NMA HCT with MSC coinfusion appeared to be safe. [less ▲]
