Enteric infections caused by Salmonella remain a major public health burden worldwide. Poultry, particularly chickens, are known to be the main reservoir for this zoonotic pathogen. Therefore, the prevention and monitoring of Salmonella infection during the live phase may greatly reduce the contamination of poultry meat during slaughter and processing. With the ban on sub-therapeutic antibiotic usage in Europe and the increasingly strictness of the European legislation on food hygiene, passive immunization by oral administration of pathogen-specific hen egg yolk antibody (IgY) may be a useful and attractive alternative. This review offers summarized information about IgY production and the use of these antibodies for passive immunization, particularly in poultry [less ▲]

The term 'locked-in'syndrome (LIS) describes a medical condition in which persons concerned are severely paralyzed and at the same time fully conscious and awake. The resulting anarthria makes it impossible for these patients to naturally communicate, which results in diagnostic as well as serious practical and ethical problems. Therefore, developing alternative, muscle-independent communication means is of prime importance. Such communication means can be realized via brain-computer interfaces (BCIs) circumventing the muscular system by using brain signals associated with preserved cognitive, sensory, and emotional brain functions. Primarily, BCIs based on electrophysiological measures have been developed and applied with remarkable success. Recently, also blood flow-based neuroimaging methods, such as functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS), have been explored in this context. After reviewing recent literature on the development of especially hemodynamically based BCIs, we introduce a highly reliable and easy-to-apply communication procedure that enables untrained participants to motor-independently and relatively effortlessly answer multiple-choice questions based on intentionally generated single-trial fMRI signals that can be decoded online. Our technique takes advantage of the participants' capability to voluntarily influence certain spatio-temporal aspects of the blood oxygenation level-dependent (BOLD) signal: source location (by using different mental tasks), signal onset and offset. We show that healthy participants are capable of hemodynamically encoding at least four distinct information units on a single-trial level without extensive pretraining and with little effort. Moreover, real-time data analysis based on simple multi-filter correlations allows for automated answer decoding with a high accuracy (94.9%) demonstrating the robustness of the presented method. Following our 'proof of concept', the next step will involve clinical trials with LIS patients, undertaken in close collaboration with their relatives and caretakers in order to elaborate individually tailored communication protocols. As our procedure can be easily transferred to MRI-equipped clinical sites, it may constitute a simple and effective possibility for online detection of residual consciousness and for LIS patients to communicate basic thoughts and needs in case no other alternative communication means are available (yet)--especially in the acute phase of the LIS. Future research may focus on further increasing the efficiency and accuracy of fMRI-based BCIs by implementing sophisticated data analysis methods (e.g., multivariate and independent component analysis) and neurofeedback training techniques. Finally, the presented BCI approach could be transferred to portable fNIRS systems as only this would enable hemodynamically based communication in daily life situations. [less ▲]

The issue of non-carbonate karst is still controversial in academic circles, there is resistance from classical karst researchers. However, in many studies throughout the world, the karst in non-carbonate rocks is a constant. Although their existence is controversial, this is due to the small amount of research conducted in these rocks had not generated a sufficient amount of information that would establish general comparison with the carbonate karst, identifying boundaries and differences. In this article, we attempted to show some of the evolution of the concept through the literature and present two examples of sandstone karst in Brazil. [less ▲]

There is worldwide increasing interest in producing ethanol from grains. Currently, maize is the main grain used in fuel ethanol production (particularly in the USA). However, in Western Europe and Canada, wheat is the main grain for ethanol plants. Barley, rye, sorghum or combinations of grains are also used. The process of ethanol production from grains generates by-products (distillers’ grains, solubles and/or gluten feed) with potential in livestock feed. Consequently, a better knowledge of chemical composition of these by-products is essential. The aim of the present study was to chemically characterise 14 batches of by-products (mainly from wheat, but also from barley and maize) purchased from some plants in Western Europe. Starch was almost completely removed by ethanol production process. Consequently, crude protein and fibre were concentrated in by-products with regard to grain value. Ratios of by-products to grain (wheat is reference) varied between 1.6 and 3.2 (protein), 1.6 and 2.7 (NDF) and 2.3 and 5.1(ADF). Furthermore, heat treatment used during the production process of dried distillers’ grains could cause destruction of important amounts of some amino acids, especially lysine (Maillard reactions). Ratios of lysine to crude protein varied among batches of byproducts and were particularly poor and unstable for distillers’ grains. In conclusion, chemical composition of European by-products of ethanol fuel produced from grains is variable. It is particularly important for wheat-based distillers’ grains. More information is needed about digestibility and availability of nutriments from these by-products. Particularly, lysine concentration and availability are probably one of the main concerns for nutritive value of by-products of ethanol fuel produced from grains. [less ▲]

Dans les Pays-Bas espagnols, morcelés par les revendications particularistes provinciales et bouleversés par d'incessantes guerres, se construit tout au long du XVIIe siècle une figure originale de la Vierge. "Reine de Guerre" et "Victorieuse", garante du pouvoir des Habsbourg et Patronne des villes, elle entre dans l'appareil symbolique que forgent les autorités pour promettre aux populations l'ordre espéré et fonder par la même occasion leur légitimité. L'A. repère et analyse les procédés qui ont contribué à définir ce rôle politique d'une Vierge puissante, triomphale et souveraine. Elle montre comment émerge cette fonction mariale tant dans la littérature pèlerine, dévotionnelle et théologique que dans les pratiques des communautés urbaines et de la Cour installée à Bruxelles [less ▲]

The present study was aimed to assess the effect of different levels of red worm (Perionyx excavatus) supplemented to the diet on growth performance and meat quality of broilers. An experiment was conducted on broilers (Ho x Luong Phuong) of 4 - 10 weeks old according to a completely randomized design with one unsupplemented group (control) and three supplemented groups corresponding to 3 worm levels in the diet, viz. 1%, 1.5%, and 2% on a dry matter basis. Results showed that the 2% worm supplemented group had the highest growth rate, higher than the control group (1925.3 kg/head vs 1822.6 kg/head at the age of 10 weeks) with P <0.05. Chicken in the supplemented groups had lower FCR. The dressing percentage, and leg meat in the 2% worm supplemented group were higher than those of the control group. The different levels of red worm supplementation did not significantly affect meat quality (pH, color, the rate of dehydration after storage and processing). [less ▲]

Within the iClass (Integrated Project 507922) and Enhanced Learning Experience and Knowledge Transfer (ELEKTRA; Specific Targeted Research or Innovation Project 027986) European projects, the author was requested to harness his pedagogical knowledge to the production of educational adaptive systems. The article identifies and documents the pitfalls of such interdisciplinary joint work. It suggests that the pedagogical added value of adaptive tools is more likely to be found in the support of human decision making regarding personalization strategies, autonomy development and metacognitive training than in the provision of highly technical automatic customization devices.

In this paper, I argue that the current legal framework as it stands offers sufficient means to refuse any effect to a marriage celebrated outside Belgium if it appears that it is a marriage of convenience. There has been much talk of strenghtening and fine tuning the legal framework in order to offer real protection against such foreign sham marriages. A thorough analysis of the law as it stands, and in particular of Article 27 of the Code of Privat International Law reveals that such fine tuning is by no means necessary. Article 27 properly applied already offers sufficient protection against such marriages. The analysis also reveals that in order to refuse effect to foreign marriages of convenience, it is not even necessary to call upon the doctrine of ordre public or of fraus legem, to which Article 27 refers. The application of these two doctrines appears to be very complex and will in most cases not be necessary. [less ▲]

We show that a remarkable compatibility exists between the results of a potential model with constituent quarks and the 1/Nc expansion mass formula for strange and nonstrange baryon resonances. Such compatibility brings support to the basic assumptions of relativistic quark models and sheds light on the physical content of the model-independent large Nc mass formula. Good agreement between both approaches is also found for heavy baryons, made of one heavy and two light quarks, in the ground state band. [less ▲]

We derive general analytic formulae for the matrix elements of the SU(6) generators for mixed symmetric $[N_c-1,1]$ spin-flavor states with an arbitrary number $N_c$ of quarks. They are relevant for baryon spectroscopy in the $1/N_c$ expansion method applied to light baryons and can be used to study excited states. In this way previous work on non-strange baryons can be extended to both non-strange and strange baryons. [less ▲]
