Meat fermentation is an important processing method with enormous nutritional and health benefits. A study was conducted to examine the sensory properties of fermented cattle and camel beef Kilishi. The effects of meat type, age and packaging on this meat quality attribute were evaluated. The experimental meat samples were fermented before utilized in Kilishi processing. The chunks of meat were sliced and then inoculated with lactic meat starter culture at three concentrations (2.5, 5.0 and 7.5 g /100 ml w/v). Kilishi samples for the sensory assessment were taken from each product lot. The experiment for the second trial was laid in a 2 x 3 x 4 factorial arrangement in a completely randomized design. The factors are two animal species (cattle and camel) aged 3, 5 and 8 years and above and four packaging arrangements: brown paper (B), polyvinyl chloride (P), aluminium foil and polyvinyl chloride (AP), brown paper and polyvinyl chloride (BP). Data generated were analysed by analysis of variance using SPSS Version 20.0 and GraphPad Instat while significantly different means were separated with Tukey HSD test. The result of sensory evaluation of the experimental Kilishi indicated that colour was ranked high and the product prepared from animals aged 5 years (middle age) and packaged in polyvinyl chloride material was the one preferred. It was concluded that fermentation and packaging improved the sensory quality of the product. Fermentation of cattle and camel beef of animals aged 5 years using 2.5% meat starter culture and the use of PVC-based package were recommended in semi-arid environment of Nigeria.     La fermentation de la viande est une méthode de traitement importante avec d'énormes avantages nutritionnels et de santé. Cette étude a été menée pour examiner les propriétés sensorielles des bovins fermentés et du Kilishi de bovins à base de chameaux. Les effets du type de viande, de l'âge et de l'emballage sur cet attribut de qualité de la viande ont été évalués. Les échantillons de viande expérimentaux étaient fermentés avant l'utilisation de la transformation du Kilishi. Les morceaux de viande ont été tranchés puis inoculés avec une culture de démarreur de la viande lactique à trois concentrations (2,5, 5,0 et 7,5 g / 100 ml w/v). Les échantillons de Kilishi pour l'évaluation sensorielle ont été prélevés sur chaque lot de produit. L'expérience du deuxième essai a été déposée dans un arrangement factoriel de 2 x 3 x 4 dans une conception complètement randomisée. Les facteurs sont deux espèces animales (bovins et chameaux) âgés de 3, 5 et 8 ans et plus et quatre arrangementsd'emballage: papier brun (P), chlorure de polyvinyle (C), feuille d'aluminium et chlorure de polyvinyle (FC), papier brun et polyvinyle chlorure (PC). Les données générées ont été analysées par analyse de la variance à l'aide de SPSS version 20.0 et du graphique PadinStat, tandis que des moyens nettement différents ont été séparés avec un test de Tukey DFS. Le résultat de l'évaluation sensorielle des Kilishi expérimentaux a indiqué que la couleur était élevée et le produit préparé à partir d'animaux âgés de 5 ans (âge moyen) et emballé dans des matériaux de chlorure de polyvinyle était celui préféré. Il a été conclu que la fermentation et l'emballage ont amélioré la qualité sensorielle du produit. Fermentation du bétail et du bœuf à base de chameaux d'animaux âgés de 5 ans en utilisant une culture de démarrage de 2,5% de la viande et l'utilisation de colis à base de PVC ont été recommandées dans un environnement semi-aride du Nigéria.

Abstract. Over a long multi-year period, flood events can be classified according to their effectiveness in moving sediments. Efficiency depends both on the magnitude and frequency with which events occur. In this study, the efficiency of the Wadi Sebdou (North-West Algeria), in a semi-arid environment, is examined through its histogram of sediment supply by discharge classes, established from 31-years of measurements. The effective (or dominant) discharge is the one whose class corresponds to the maximum sediment supply. Three types of subdivisions into discharge classes were compared. The subdivision in classes of equal amplitudes and the subdivision with equivalent discharges were those which allowed a correct distribution of frequencies and supplies of water and sediments. The effective discharges for these two subdivisions were close and almost equal to the half load discharge, i.e. to the flow rate corresponding to 50% of the cumulative sediment yield. The substitution of the flow histogram by a probability relationship and the use of a sediment rating curve enable to infer a theoretical value of the effective discharge. In this basin with strongly irregular flows, the introduction of a probability distribution was tested and assessed, analytical solutions are provided, but the Log-normal and Log-Gumbel laws highly underestimated the effective discharge. Return periods, estimated from the annual series of maximum discharge and half-load discharge, were compared. The former gives the period between hydrological years with discharges higher than the effective discharge (around 2 years), and the latter shows that more than half of the yearly sediment supply is carried by flows higher than the effective discharge only every 7 hydrological years. The study finally emphasized that the distribution of suspended load as a function of liquid discharge was sensitive to the basin and its forcings. On the Wadi Sebdou, the distribution of the sediment load, bimodal before 1988, became essentially monomodal after this date.

ABSTRACT This study aimed to evaluate gas exchange of banana Prata in two production cycles in semiarid environment. Six cultivars were used as treatments arranged into a completely randomized design with five replications and four plants per plot. For physiological characteristics, it was considered a factorial arrangement of 6x14x2, six cultivars, 14 periods (months), two readings, 8:00 and 14:00 in each period. The rates of gas exchange, the carboxylation efficiency and the instantaneous efficiency of water use were higher at 8:00 and lower at 14:00, with rare exceptions. The ‘BRS Platina’ had a higher leaf temperature, higher transpiration and lower water use efficiency. ‘Prata-Anã’, ‘FHIA-18’ and ‘Maravilha’ expressed lower leaf temperature and lower transpiration. The ‘Maravilha’ is the most efficient in water use. Transpiration increases linearly with the leaf temperature, while the instantaneous efficiency of water use decreases linearly.

A total of one hundred and forty four grower (56-84d) turkeys were used to investigate the effect of dietary supplemental L-arginine on growth response, physico-chemical and sensory properties of the resultant breast meat. Dietary treatments consisted of basal diet supplemented with 0 (control), 0.05 and 0.10% L-arginine, respectively. A completely randomized design was used with turkeys randomly allotted to 18 pens; each pen housed eight birds. Six pens were assigned to each treatment. Growth performance of the birds, cook loss, refrigeration loss, freeze loss and water absorptive power of the breast meat were measured. Finisher turkeys fed diet supplemented with 0.05 % L-arginine and control group had reduced (P < 0.05) feed intake and improved (P < 0.05) feed conversion ratio. Meat samples from turkeys fed diet supplemented with L-arginine showed increased (P<0.05) cook loss weight (in g) and percentage cook loss when compared with control group. Turkeys fed diet supplemented with 0.10% arginine had the highest (P<0.01) percentage refrigeration loss, freeze loss weight (g) and percentage freeze loss. Increasing supplementation level of arginine showed a linear reduction (P<0.001) in the thaw weight of breast meat. Sensory parameters of meat sample were not influenced (P>0.05) by varying level of arginine supplemented. In conclusion, arginine supplementation seems to weaken the muscular cross-bridges in breast meat and hence resulted in higher cook loss, refrigerated loss and freeze loss.

Algeria is the largest country in Africa characterized by semi-arid and arid sites, located in the North, and hypersaline zones in the center and South of the country. Several autochthonous plants are well known as medicinal plants, having in common tolerance to aridity, drought and salinity. In their natural environment, they live with a great amount of microbial species that altogether are indicated as plant microbiota, while the plants are now viewed as a “holobiont”. In this work, the microbiota of the soil associated to the roots of fourteen economically relevant autochthonous plants from Algeria have been characterized by an innovative metagenomic approach with a dual purpose: (i) to deepen the knowledge of the arid and semi-arid environment and (ii) to characterize the composition of bacterial communities associated with indigenous plants with a strong economic/commercial interest, in order to make possible the improvement of their cultivation. The results presented in this work highlighted specific signatures which are mainly determined by climatic zone and soil properties more than by the plant species.
