Poly(hydroxyurethane) (PHU) thermosets reinforced with (functional) nanofillers were developed to design high performance adhesives for bare aluminum. Solvent-free cyclic carbonate/amine/PDMS formulations loaded with native, epoxy- or cyclic carbonate-functionalized ZnO nanofillers were premixed before deposition and thermal curing onto Al. The results highlight that the addition of PDMS prevents PHUs from delamination of the Al surface by increasing the adhesive hydrophobicity and thus limiting the water uptake. The dispersion of functional fillers within PHUs improves their thermal and mechanical properties. Benchmarking of the adhesive performances of the reinforced PHU glues with existing PHU formulations attests for the benefits of dispersing functional fillers and PDMS within the resin and evidences a 270% increase of the shear strength of reinforced PHUs adhesives compared to formulations reported in the literature.

Foot and mouth disease (FMD) has been one of the most important epizootic diseases in several cloven-hoofed animals including buffaloes, causing severe economic losses in Vietnam. This study aimed at observing clinical indicators, physiological parameters, haematological and blood chemistry values of 30 buffaloes naturally infected with FMD virus (FMDV). The study was undertaken from January 2015 to February 2016 in Hanoi, Vietnam. Results show that buffaloes infected with FMDV displayed significantly higher fever, increased respiratory rate and increased heart frequency compared to healthy animals. Moreover, FMDV-infected animals always showed high fever and vesicular stomatitis, often showed edging nail congestive inflammation and, sometimes only, blisters on the nipple. Haematological indicators showed that FMDV-infected buffaloes were dehydrated (increased total protein). Besides, infected animals also underwent anaemia as mean corpuscular haemoglobin and mean corpuscular haemoglobin concentrations were plummeted. Total white blood cell count plummeted too, especially the number and proportion of neutrophils. Meanwhile, the number and proportion of lymphocytes sharply increased compared to healthy animals. Infected buffaloes also displayed signs of liver and heart damages as judged by an increase in concentration of AST and ALT, while there was not renal damage since creatinine concentration remained stable [less ▲]

The objective of this study is to make an inventory of the honey production in the counties of Bejaia and Tizi-Ouzou in northeastern Algeria. To achieve this, a survey was carried out on 31 beekeepers (14 in Bejaia and 17 in Tizi-Ouzou). The survey shows a social, cultural and religious role for 61.29% of the beekeepers. The beekeeping is primarily held by men (93.55%). It is the basic source of income for 64.52% of the respondents. The average age of the beekeepers is 42.90years (Min-Max: 28-67 years, Median: 40.5 years). The main products of the hive are honey (100%), swarms (16.13%), royal jelly (9.68%) and propolis (9.68%). The average honey production per hive is 7.70kg (Min-Max: 0.4-15kg hives, Median: 10kg). The average number of hives per beekeeper is 42.20 hives (Min-Max: 3-300 hives, Median: 17.50 hives). The average selling price of one kg of honey is 4000.00 DA / kg (Min-Max: 2000-5000DA; Median: 4000DA). The phenotype of the bee reported by 74.19% of the surveys is of small size with a long body and dark pigmentation corresponding to the breed “Apis mellifera intermissa”. Two apiculturists described another phenotype corresponding to the “Apis mellifera major”. The factors behind the motivations for beekeeping are consumption of honey (100%), income generation (90.32%), hobby (58.06%) and conservation of biodiversity (22.58%). The multiple constraints associated with several diseases, notably Varroase (mentioned by 80.65% of beekeepers), cause difficulties for the breeders. Thus they cannot profit maximum from beekeeping. Other constraints which were reported are; forest fires (35.48%), wasps (32.26%), absence of beekeeping professionals or technicians (29.03%), harsh and cold winters with snow (19.35%), high density of hives in the region (16.13%) and uncontrolled spreading of pesticides and crop protection products at farms (12.90%). The economic situation of the Algerian beekeepers can be optimized by improving the production potential of the local bees. [less ▲]

Poultry farming is the first sector of livestock that has been industrialized. The poultry sector plays an important role in the GDP of Vietnam. It is the second largest livestock after the pig livestock. The production and consumption of eggs in Vietnam is estimated as 5.64 billion and 102.6 eggs per person per year respectively. The aim of this study was to assess the quality of eggs in relation to the chicken breed and different marketing channels in Hanoi, Vietnam. In total, 431 chicken eggs were purchased from four different marketing channels in Hanoi, including households (89 eggs), supermarkets (152 eggs), public markets (130 eggs) and small grocery stores (50 eggs). Out of the 431 above-mentioned eggs, 119 eggs came from the commercial chicken breeds and 312 eggs from traditional local breeds. The quality of eggs for a consumer is represented by its cleanliness, nutritional quality, freshness, and price. A series of measurements is carried out just after their purchase. According to the breed and the marketing channel, highly significant differences (P <0.05) were found in the freshness of the eggs (Haugh units), egg prices, eggs weight, egg shell, the white and the yolk of the egg. Though the chicken breed and marketing channels do not significantly affect (P> 0.05) the freshness of the eggs, however, they have a significant effect (P <0.05) on the size of the eggs marketed in Hanoi. The results of this study show an important diversity in marketing channels and marketed eggs in Hanoi. [less ▲]

The Late Devonian period was affected by major, irreversible changes including two of the most severe biodiversity crises in Earth’s history, the so-called Kellwasser and Hangenberg Events (respectively at the Frasnian – Famennian and the Famennian – Carboniferous boundaries). Currently, hypotheses for the Late Devonian extinctions include sea-level fluctuations and regression, climate cooling, ocean anoxia, massive volcanism and/or bolide impact. Unfortunately, testing these hypotheses is impaired by a lack of sufficient temporal resolution in paleobiological, tectonic and proxy climate records. Recent advances in astronomical dating have improved the accuracy of the Frasnian time scale and part of the Famennian (De Vleeschouwer et al., 2012, 2013). However, the time duration of the Famennian stage remains poorly constrained even though this is the key to understanding cause-and-effect relationships of the Late Devonian greenhouse–icehouse transition and the onset of the end Famennian glaciation that ultimately led to the Hangenberg Event at the Devonian–Carboniferous boundary. During the Late Devonian an epieric sea in mid-continent North America occupied the Illinois Basin onto which a Late Frasnian – Early Carboniferous sequence of deep-shelf deposits was archived. A complete record of this sequence, mainly composed of marl, organic-rich shale, silty-shale and carbonate, is captured in three overlapping cores stored in the Iowa Geological Survey (H-30, Sullivan Slough and H-32). H-30 records the Frasnian-Famennian boundary, the Sullivan Slough covers almost all the Famennian (middle triangularis-upper expansa conodont zones) and H-32 spans the junction between the uppermost Famennian and lowermost Carboniferous. To have the best chance of capturing Milankovitch cycles (long- and short-eccentricity cycles as well as obliquity and precession), 2200 rock samples were collected at 5-cm intervals across the entire sequence. Magnetic susceptibility (MS) was measured on each sample and the preservation of paleoenvironmental/climatic information into the signal was verified through geochemical analyses (Ti, Al, Zr by XRF) and magnetic measurements (low temperature magnetic susceptibility and IRM acquisitions). Correlation and overlap between each core was made using available conodont biostratigraphy and then refined by comparing the trends in the MS and δ13C signals for critical intervals. To estimate the duration of the Famennian stage we applied multiple techniques on the MS signal (multitaper method, evolutive harmonic analysis and adaptive-weighted harmonic F-test). By combining these techniques, we identified highly stable 405-kyr cycles across the Sullivan Slough and the H-32 cores. 405-kyr cycles were not observed in H-30, but 100-kyr cycles were identified. A preliminary estimate of the duration for the Famennian stage using the 405-kyr cycle as chronometer constrains the duration of the Famennian stage to 13 ± 0.4 Myr with an average sedimentation rate of 0.5 cm/kyr across the sequence.

Rab guanine nucleotide exchange factor (GEF-)1 (Rabgef1), a multifunctional protein whose in vivo functions remained unknown until recently, is highly expressed in mouse and human epithelial cells. The aim of this study is to investigate the role of Rabgef1 in intestinal epithelial cells (IECs) and intestinal homeostasis in mice. We performed conditional deletion of Rabgef1 gene using the cre-lox system to obtain mice lacking Rabgef1 specifically in IECs (Rabgef1IEC-KO), under the wild-type (WT) or the colitis-prone Interleukin-10 (Il-10)-deficient background. In addition, we used the CRISPR-Cas9 technology to obtain a murine IEC line deficient in Rabgef1. Rabgef1IEC-KO mice under the WT background did not develop spontaneous intestinal abnormalities but exhibited an altered intestinal microbial composition associated with minor changes in IEC pro-inflammatory gene expression profile. Moreover, Rabgef1IEC-KO mice exhibited an increased susceptibility to inflammation in a dextran sodium sulfate (DSS)-induced model of colitis under the WT background, as well as in a constitutive model of colitis under the Il-10-¬deficient background. In vitro, we showed that mouse IECs lacking Rabgef1 significantly overexpressed several pro-inflammatory cytokines and chemokines as compared to control cells. Taken together, these results support that Rabgef1 acts as a regulator of intestinal homeostasis and inflammation, and that dysregulated Rabgef1 expression could contribute to intestinal barrier dysfunction in inflammatory conditions of the gut.

In Algeria, the ingredients used in the broiler feed are exclusively imported from abroad, which affects negatively the production cost of the chicken meat and its sale price in the market at national level. Because of the wide diversity in soil and climate, Algeria has a substantial number of plants which can be used in animal feed. This work is part of the valuation of the feed potential of the barbaric fig tree, widely present in the Algerian rural landscape, for the broiler chicken. The Opuntia ficus-indica is known for its edible fruits and for use of its fleshy leaves or “racquets” as fodder especially during periods of drought. It is also used to control the water and wind erosion as well as for the protection and improvement of soil fertility in arid and semi-arid regions. The aim of this study was to measure the effects of Opuntia ficus-indica powder on growth performance, serum composition and carcass yield of broiler chickens. The experiments were performed in a private poultry farm in the Chemini region (Wilaya de Bejaia). In this study, 120 Ross-308 day-old male chicks were monitored. They were divided in 3 groups (Group 1, 2 and 3) according to the specific diet (4 x 10 chicks / group). The group 1 was offered commercial feed. The group 2 and group 3 were offered the same commercial feed as group 1 but 5% and 10% of the commercial feed was replaced by the Opuntia ficus-indica powder respectively. The Opuntia ficus-indica powder did not show any negative effect (p>0.05) on the final body-weight, average daily gain and carcass yield. However, it decreased (p<0.05) the biochemical parameters -blood concentration- (plasma glucose, uremia, cholesterol and triglycerides). In conclusion, the Opuntia ficus-indica powder has the potential to be used in poultry feed to reduce the cost of broiler feed in Algeria [less ▲]

Partiendo de la estructura de un proyecto de tesis, esta charla esboza primero un estado de la cuestión relativo a la autoficción "fantástica", de Colonna (2004) hasta Casas (2015), pasando por Alberca (2007, 2012). Basándonos en diversas teorías de lo fantástico, explicamos los motivos que nos conducen a rechazar el empleo del calificativo "fantástico", y sugerimos otro, menos específico. Pasamos luego al análisis de algunos rasgos formales —tipo de mímesis y artificialidad entre otros— y temáticos —el cuerpo, el sexo y el espacio—, antes de especular respecto a la posible relación entre la autoficción "fantástica" y el contexto histórico, social y político de su emergencia. Nuestra hipótesis, inspirada en las ideas defendidas por Molkou (2002) y Alberca (2007), es que estaría íntimamente vinculada a la "violencia", entendida en sentido amplio. [less ▲]

Over the past few years, the number of publications about lung microbiota has considerably increased due to the advancement of new molecular technologies. In dogs, only two studies in healthy experimental beagles have been published. Interestingly, we recently reported major differences in the lung microbiota composition and diversity between experimental healthy beagles and healthy client-owned West Highland white terriers (WHWT) suggesting an impact of the breed or of the living environment on lung microbiota composition. Accordingly, to further assess the effect of living environment, the aim of the present study was to compare lung microbiota data obtained in healthy WHWT (n = 5) living in Finland with those previously obtained in healthy WHWT (n = 5) living in Belgium. For this purpose, bronchoalveolar lavage was retrospectively selected. Metagenetic analysis were performed after DNA extraction and sequencing on a MiSeq Illumina sequencer. Taxonomical assignation and microbiota community analysis were done with MOTHUR V1.35 with an OTU clustering distance of 0.03. Data analyses demonstrated that the same 4 major phyla Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes predominated in both groups of dogs. Significant but subtle differences were observed between groups. Results of the present study do not demonstrate a clear impact of the living environment on lung microbiota composition. In conclusion, analysis of larger cohorts of healthy dogs with various living conditions appears necessary. [less ▲]

Class A β-lactamases have been widely used as versatile scaffolds to create hybrid (or chimeric) proteins for a series of applications ranging from basic research to medicine. We have, in particular, used the β-lactamase BlaP from Bacillus licheniformis 749/C (BlaP) as a protein scaffold to create model polyglutamine (polyQ) proteins in order to better understand the mechanism(s) by which an expanded polyQ sequence triggers the formation of amyloid fibrils. The model chimeras were designed by inserting a polyQ sequence of various lengths at two different locations within BlaP (i.e. position 197 or position 216) allowing a detailed comparison of the effects of subtle differences in the environment of the polyQ sequence on its ability to trigger protein aggregation. In order to investigate the effects of the polyQ insertion at both positions on the structure, stability and dynamics of BlaP, a series of NMR experiments including H/D exchange are foreseen. Accordingly, as necessitated by these studies, here we report the NMR assignment of the wild-type BlaP (BlaP-WT) and of the two reference proteins BlaP197Q0 and BlaP216Q0, wherein a dipeptide Pro-Gly has been introduced at position 197 and 216, respectively; this dipeptide originates from the addition of the Sma1 restriction site at the genetic level to allow further polyQ sequence insertion.
