Influence of Raspberry and Its Dietary Fractions on the In vitro Activity of the Colonic Microbiota from Normal and Overweight Subjects

Raspberry is a source of dietary fibre and phenolic compounds, which are metabolised by the gut microbiota, resulting in the production of short chain fatty acids (SCFAs) and phenolic catabolites; but the formation of these compounds depends on the microbiota composition. The aim of this study was to investigate whether the raspberry and its fractions (phenolic extract, total and insoluble dietary fibre) affect the microbial activity depending on the body weight condition. For this, in vitro fermentations of raspberry fractions were carried out using faeces from normal-weight (NW) and overweight volunteers (OW) during 48 h, and phenolic catabolites and SCFAs were analysed at 0, 6, 24 and 48 h. The whole raspberry and the phenolic extract produced greater quantities of urolithins and total SCFAs when compared with fibre fractions, reaching the highest amount between 24 and 48 h. The body weight condition was an important factor, since faeces from NW led to greater production of urolithins from non-extractable phenolic compounds bound to fibre fractions, whereas in OW the urolithins production was higher from the fractions with more extractable polyphenols. In summary, the whole raspberry has been shown to have a prebiotic effect, mainly due to its phenolic compounds content rather than its fibre content.

Variations in The Distance Between Hulls that Affect the Resistance of The Floating Pontoon N219

An amphibious plane is an aircraft to carry out cargo delivery and an aircraft for emergencies to reach remote islands in the archipelago. A pontoon or buoy is a hull that is useful as a bearing for landings in water areas. This is done to assist aircraft landing without using an airplane runway. This research aims to create a new configuration of the distance between one pontoon and another. Numerical calculations and analysis are useful for seeing the characteristics of the floating pontoon design's resistance. An investigation of interference waves was also carried out in this study to validate the experimental data generated by the pontoon hull. Numerical calculations are carried out on the CFDSOF application to predict hull resistance with three variations to the floating pontoon's separation distance. The simulation is carried out at the Operating Empty Weight condition on the Indonesian Aerospace aircraft with the IAe N219 model. The results show that the Froude Number speed is between 0.3 to 0.8. There is a reduction in drag on the hull so which makes takeoff operations easier.

Genetic Parameters and Genome-Wide Association Studies of Quality Traits Characterised Using Imaging Technologies in Rainbow Trout, Oncorhynchus mykiss

One of the top priorities of the aquaculture industry is the genetic improvement of economically important traits in fish, such as those related to processing and quality. However, the accuracy of genetic evaluations has been hindered by a lack of data on such traits from a sufficiently large population of animals. The objectives of this study were thus threefold: (i) to estimate genetic parameters of growth-, yield-, and quality-related traits in rainbow trout (Oncorhynchus mykiss) using three different phenotyping technologies [invasive and non-invasive: microwave-based, digital image analysis, and magnetic resonance imaging (MRI)], (ii) to detect quantitative trait loci (QTLs) associated with these traits, and (iii) to identify candidate genes present within these QTL regions. Our study collected data from 1,379 fish on growth, yield-related traits (body weight, condition coefficient, head yield, carcass yield, headless gutted carcass yield), and quality-related traits (total fat, percentage of fat in subcutaneous adipose tissue, percentage of fat in flesh, flesh colour); genotypic data were then obtained for all fish using the 57K SNP Axiom® Trout Genotyping array. Heritability estimates for most of the 14 traits examined were moderate to strong, varying from 0.12 to 0.67. Most traits were clearly polygenic, but our genome-wide association studies (GWASs) identified two genomic regions on chromosome 8 that explained up to 10% of the genetic variance (cumulative effects of two QTLs) for several traits (weight, condition coefficient, subcutaneous and total fat content, carcass and headless gutted carcass yields). For flesh colour traits, six QTLs explained 1–4% of the genetic variance. Within these regions, we identified several genes (htr1, gnpat, ephx1, bcmo1, and cyp2x) that have been implicated in adipogenesis or carotenoid metabolism, and thus represent good candidates for further functional validation. Finally, of the three techniques used for phenotyping, MRI demonstrated particular promise for measurements of fat content and distribution, while the digital image analysis-based approach was very useful in quantifying colour-related traits. This work provides new insights that may aid the development of commercial breeding programmes in rainbow trout, specifically with regard to the genetic improvement of yield and flesh-quality traits as well as the use of invasive and/or non-invasive technologies to predict such traits.

EXPERIMENTAL STUDY AND ANALYSIS OF FLAT BELT CONVEYER SYSTEM WITH DIFFERENT WEIGHT CONDITION

A conveyor belt system essentially consists of an endless belt of elastic material connected between two flat pulleys and driven by the rotation of one of the pulleys by a direct current motor. Usually, the material is fed to the belt near the other end of the pulley. The moving belt that carries the material to the drive pulley tends to sag between the two end pulleys due to its own weight. Rubber conveyor belts are commonly used to transport items with uneven bottom surfaces, small items that fall between rolls, or product bags that sag between rolls.

COMPARISON OF SCALE WEIGHTS TO TAPE ESTIMATES AND THEIR RELATIONSHIPS WITH CONDITION SCORES IN BUNAJI CATTLE

Animal weighing facilities are not available in many African farming conditions. Indirect methods of estimating animals weights have been compared with scale weights and, in some cases. condition scores. The use of calibrated weigh bands is not widely practised probably because calibrations were based on temperate breeds. A study was carried out to determine the relationship between scale, tape measurement and weighband estimates of Bunaji cattle. These were then related to the animals' condition scores. Both the tape measurement and management and research purposes. When weigh band weights significantly (P<0.001) correlated (r = 0.95 and 0.94 respectively) with the scale weight. Condition score significantly is (P<0.001) correlated with the tape meaşurement, scale and weighband weights (r = 0.62, 0.67 and 0.64 respectively). The correction factors of the regression coefficients of determining weight from condition score for the three methods varied by only 3.92. It is suggested breed. that in the absence of weighing facilities, reliable estimates can be obtained by either tape measurement or weighband methods. Condition score can also reliably be used to estimate the weight using the regression coefficients obtained. Weighbands will be easier to use in field conditions. The need to calculate the weight from a formula could introduce errors when using the tape measurement method.

THE INDUCTIVE BLOCKWISE ALPERIN WEIGHT CONDITION FOR TYPE AND THE PRIME

We establish the inductive blockwise Alperin weight condition for simple groups of Lie type $\mathsf C$ and the bad prime $2$ . As a main step, we derive a labelling set for the irreducible $2$ -Brauer characters of the finite symplectic groups $\operatorname {Sp}_{2n}(q)$ (with odd q), together with the action of automorphisms. As a further important ingredient, we prove a Jordan decomposition for weights.
