Production of Djallonke sheep at an experimental station in the guinean zone of Benin. Reproduction performance and influence of non-genetic factors From 1994 to 2002, data from Djallonke sheep were collected for reproduction performance. The data were obtained from the farm of the Faculty of Agronomic Sciences (University of Abomey Calavi). Data analysed by GLM procedure and Student’s t-test, were used to identify and quantify non-genetics factors affecting the age at first lambing, intervals between lambing and prolificacy. Results indicated: age at first lambing, 609.64days±110.26 days; intervals between lambing, 243.01days±68.19days; prolificity, 1.28±0.45; annual reproduction rate, 1.92%; temporary sterility rate, 5.79%. Lambing season, lambing year and the year*season interaction affected significantly (p<0.01) the age at first lambing and the interval between lambing. The same factors were not significant (p>0.05) for prolificacy. [less ▲]

In this contribution we review the current status of the determination of the rotational frequency in non-radially pulsating B stars, i.e. beta Cep stars and slowly pulsating B stars. Considerable progress is currently being made in the understanding of the non-radial oscillations of main-sequence B Stars by means of high-temporal, high-spatial resolution spectroscopic time series. This has led to the detection of frequency multiplets, which are interpreted as rotationally splitted non-radial modes and which allow an accurate determination of the surface rotational frequency in some stars. We outline how our future goal, i.e. the derivation of the internal rotation frequency, can be achieved. [less ▲]

Collagen-induced arthritis (CIA) in mice is accompanied by splenomegaly due to the selective expansion of immature CD11b(+) myeloblasts. Both disease manifestations are more pronounced in interferon-gamma receptor knock-out (IFN-gammaR KO) mice. We have taken advantage of this difference to test the hypothesis that the expanding CD11b(+) splenic cell population constitutes a source from which osteoclast precursors are recruited to the joint synovia. We found larger numbers of osteoclasts and more severe bone destruction in joints of IFN-gammaR KO mice than in joints of wild-type mice. Osteoclast-like multinucleated cells appeared in splenocyte cultures established in the presence of macrophage colony-stimulating factor (M-CSF) and stimulated with the osteoclast-differentiating factor receptor activator of NF-kappaB ligand (RANKL) or with tumour necrosis factor-alpha (TNF-alpha). Significantly larger numbers of such cells could be generated from splenocytes of IFN-gammaR KO mice than from those of wildtype mice. This was not accompanied, as might have been expected, by increased concentrations of the intracellular adaptor protein TRAF6, known to be involved in signalling of RANKL- and TNF-alpha-induced osteoclast formation. Splenocyte cultures of IFN-gammaR KO mice also produced more TNF-alpha and more RANKL than those of wild-type mice. Finally, splenocytes isolated from immunised IFN-gammaR KO mice contained comparatively low levels of pro-interleukin-1beta (pro-IL-1beta) and pro-caspase-1, indicating more extensive conversion of pro-IL-1beta into secreted active IL-1beta. These observations provide evidence that all conditions are fulfilled for the expanding CD11b(+) splenocytes to act as a source of osteoclasts and to be indirectly responsible for bone destruction in CIA. They also provide a plausible explanation for the higher susceptibility of IFN-gammaR KO mice to CIA. [less ▲]

In 1995, a Peer Review Commission Radiotherapy was installed at the initiative of the Belgian Ministry of Health as part of a larger pilot project on quality assurance. This commission was composed of 14 members, 8 radiation oncologists (appointed by the Belgian Association of Radiation Oncology) and 6 physicists (appointed by the Belgian Association of Hospital Physicists). Peer review is only one of the activities within the Quality control of the medical performance aiming to improve quality in diagnostic and therapeutic procedures. Other activities in Quality assurance are development of standards and guidelines, continuous education and measurements of the treatment process. In 1998, the Peer review Commission Radiotherapy has proposed to make a survey of rectal cancer management including diagnostic procedures and therapeutic approaches. More than 1300 questionnaires were sent to the chairman of the 25 Belgian radiotherapy departments, asking them to have it filled in by the radiation oncologist in charge of rectal cancer treatment in their department and to all the known surgeons from a list provided by the Ministry of Health. The paper reports and discuss the results of this survey. [less ▲]

"Regular model checking" is the name of a family of techniques for analyzing infinite-state systems in which states are represented by words or trees, sets of states by finite automata on these objects, and transitions by finite automata operating on pairs of state encodings, i.e. finite-state transducers. In this context, the central problem is then to compute the iterative closure of a finite-state transducer. This paper addresses the use of regular model-checking like techniques for systems whose states are represented by infinite (omega) words. Its main motivation is to show the feasibility and usefulness of this approach through a combination of the necessary theoretical developments, implementation, and experimentation. The iteration technique that is used is adapted from recent work of the authors on the iteration of finite-word transducers. It proceeds by comparing successive elements of a sequence of approximations of the iteration, detecting an "increment" that is added to move from one approximation to the next, and extrapolating the sequence by allowing arbitrary repetitions of this increment. By restricting oneself to weak deterministic Buchi automata, and using a number of implementation optimizations, examples of significant size can be handled. The proposed transducer iteration technique can just as well be exploited to compute the closure of a given set of states by the transducer iteration, which has proven to be a very effective way of using the technique. Examples such as a leaking gas burner in which time is modeled by real variables have been handled completely within the automata-theoretic setting. [less ▲]

Surfactants play a key role in the biotechnological degradation of hydrophobic substrates, however this role is often misunderstood. During the biotransformation of methyl ricinoleate into the aroma compound γ-decalactone by the yeast Yarrowia lipolytica, a direct contact occurs between the surface of the cells and the small droplets of substrate. The impact of a series of surfactants on this process was investigated. Both ionic surfactants tested were toxic towards the yeast. This effect may be linked to a decrease in the cell membrane integrity. The interfacial area of the emulsion varied according to the non-ionic surfactant used, and this factor was correlated with the productivity of the biotransformation. By evaluating the effect of surfactants on the capacity of the cells to adhere to decane (MATH test), it was shown that the adhesion of methyl ricinoleate on yeast surface is not a rate-limiting point for the process. © 2004 Elsevier B.V.
