A study was carried out on 168 heads of broiler chicken (Ho x Luong Phuong) from 5 to 12 weeks of age to measure the effect of red worm meal (Perionyx excavatus) used as a rich protein feed in the diet on growth performance, feed conversion and meat quality. Based on a completely randomized design, chickens were divided into four groups, involving a control group and three experimental groups corresponding to three levels of red worm meal, viz 8 and 6g/kg of feed (level 1), 13 and 10g/kg of feed (level 2), 18 and 14 g/kg of feed (level 3) according to two respectively growth periods of chicken (from 5 to 8 weeks of age and from 9 to 12 weeks of age. The results showed that supplementation of redworm meal with level 3 in the diets resulted in higher growth rate (P<0.05), lower feed consumption (reducing by 0.53 kg of feed/kg of weight gain, equal to 13.8%) and more improved of yellowness value (P<0.05) than those of control group. Adding redworm to chicken’s diets didn’t affect significantly other characteristics of meat quality (pH, drip and cooking loss, L* and a* values). If cost of worm is not calculated, feed price and feed cost per each kilogram of weight gain in group 3 will be reduced by 287 VND/kg and 4278 VND/kg, corresponding to 4.51% and 17.47% as compared with those of control one.

Since the days the investigating officers used ”pin maps” to locate and to think about crime events, crime mapping has become widespread thanks to spatial analysis mainly supplied by GIS-like software. In particular these methods suit well to geographic profiling devoted to crime series characterised by a single offender and hence limited space and time variability. Although spatial techniques are now regularly performed to delineate an offender’s area of residence, the temporal dimension is underemployed due to the wider uncertainty of time records. This paper proposes a methodology based on a least-squares adjustment in order to cope with this temporal issue for determining the most probable offender’s residence. Moreover, a chi-square test is described to check the significance of the solutions suggested by the method. The process is carried out on the real road network which has been discretised (rasterised) for computing convenience. Three simulations show the validity of the reasoning. Finally the main time and speed assumptions introduced in the model are discussed paving the way for further research. [less ▲]

The genetic mechanism controlling sexual differentiation had remained unknown for a long time. Karyotype analysis of sex-inverted patients or individuals with ambiguous sexual differentiation has enabled the localization and identification of genes involved. It is currently known that the SRY gene is responsible for the initiation of a cascade reaction leading to male differentiation of the primitive gonad. SRY is a +/- 820 base pairs gene located on the small arm of the Y chromosome, more precisely within the 1A1 alpha sub-segment. Although a few other genes are known to be involved in the downstream regulation of SRY, their precise mode of action is yet unknown. [less ▲]

Growth probability and kinetic models for Listeria monocytogenes in response to multiple hurdles occurring during cheese anufacturing are mainly focused on suspended L. monocytogenes cells. This study aimed to compared: (i) the growth/no growth interface of L. monocytogenes cells attached on stainless steel (SS) surfaces, or in suspension, within adjusted media and (ii) the behavior of planktonic and detached Listeria cells during manufacturing and ripening of two popular Greek cheeses: Feta and Graviera. A multi-strains composite of L. monocytogenes isolates from cheese, factory and farm in Greece and Ireland, were grown in TSBYE, MRD, Milk, Feta and Graviera cheese in the presence of SS coupons (2x5cm) for 3d at 20 °C, to obtain the following inocula: planktonic cells (P), and cells detached from the SS coupons (D). Detachment took place by the bead vortexing method. For growth/no growth evaluation P and D cells were inoculated in TSBYE, adjusted to 5 pH (6.8-4.8) by lactic acid and at 4 aw (0.945-0.995) by NaCl. For evaluation of L. monocytogenes kinetics in cheese, P and D cells were inoculated at three simulated stages of Feta and Graviera manufacture: in pasteurized milk, after cutting the curd and after the first ripening. The growth of D cells slightly delayed compared to P cells while it was more affected by aw than pH. On cheese, L. monocytogenes survived throughout the ripening at low levels. The differences in probability of growth of single cells for both inocula (P and D) were assessed by stochastic approaches. Furthermore, PFGE analysis resulted that 91 % of the cells of any tested condition belonged to the cheese factory isolate. The re- sults may address safety implications relevant to the potential of attached cells to proliferate, whereas data may contribute to filling data gaps on risk assessment of L. monocytogenes isolates from the dairy industry.

Protection zones delimited by isochrones are often computed using calibrated groundwater flow and transport models. In heterogeneous formations, all direct (hard) and indirect (soft) data must be used optimally. Approaches involving in situ pumping and tracer tests, combined with geophysical and/or other geological observations, should be developed. In a deterministic framework, the calibrated model is considered to be the best representation of reality at the current investigation stage, but uncertainty of the results is not quantified. Using stochastic methods, a range of equally likely isochrones can be produced, allowing us to quantify the influence of our knowledge on the aquifer parameters on protection-zone uncertainty. Furthermore, integration of soft data in a conditioned stochastic generation process, possibly associated with an inverse modelling procedure, can reduce the resulting uncertainty. Proposed is a stochastic methodology for protection-zone delineation, integrating hydraulic conductivity measurements (hard data), head observations and electrical resistivity data (soft data).

Ekofisk, located 200 km west of the Norwegian coast, is one of the main oilfields in the North Sea. Since the early 1980s severe compaction of chalk reservoir layers has been observed as a consequence of reservoir depletion during oil production. Subsequently, this compaction has been amplified by assisted oil recovery using seawater flooding. The development of our understanding of the inherent mechanisms of this phenomenon has been the objective of extensive experimental investigations in the last two decades. Owing to the very high cost of cored material from the reservoir, experiments are usually performed on chalk samples from an outcrop in Belgium lying at the same stratigraphic level as the Ekofisk reservoir chalks. However, even at the laboratory sample scale,. experimental variability of material response is observed. From a theoretical and numerical point of view, the determination of the mechanical properties of the material is of utmost importance for accurate modelling at both sample scale (laboratory tests) and reservoir scale. The aim of this paper is to introduce a stochastic approach within a deterministic constitutive model of chalk to enable the influence of material heterogeneity to be included in analyses for the range of observed mechanical responses. In modelling the random distribution of material parameters, the time-consuming Monte Carlo simulation method is replaced by a more efficient stochastic modelling technique. The results are given in the form of statistical parameters for the experimental laboratory test responses. The parameters of the distribution law (mean value, range of variation, spatial correlation structure) are fitted to reproduce the range of experimental responses observed at sample scale. Interest is focused on the variability of the chalk bulk modulus, as observed during isotropic compression tests. The proposed methodology provides a satisfactory explanation for the variability of response observed at the sample scale. The potential for extending the proposed approach to reservoir scale is briefly discussed. [less ▲]
