Development of oxidation models and analytical techniques specific to phospholipids and their degradation products in functional foods

Among the numerous beneficial effects of phospholipides can highlight their role in protecting the cardiovascular system and improving memory and learning. These effects can be partially explained by the fact that phospholipids are rich in polyunsaturated (eicosapentaenoic and docosahexaenoic acids) or essential fatty acids. Thus, it is very significant to explore potential food sources containing polyunsaturated rich phospholipids for the development new food products supplemented with phospholipids.This work allowed a series method for the extraction, purification, separation and quantification of phospholipids in order to characterize the polyunsaturated phospholipid sources. Food supplementation with polyunsaturated phospholipids rises however the question of their stability during food processing at high temperature. Then we have developed methods to identify phospholipids degradation products and determine their kinetics of the oxidation during thermal treatment which is a widespread food processing.Phospholipids (PE and PC) are more stable than triacylglyceride, this is due to the presence of an amino group in the molecule.
Queries on Compressed Data

Low-latency, high-throughput systems for serving interactive queries are crucial to today's web services. Building such systems for today's web services is challenging due to the massive volumes of data they must cater to, and the requirement for supporting sophisticated queries (e.g., searches, filters, aggregations, regular expression matches, graph queries, etc.). Several recent approaches have highlighted the importance of in-memory storage for meeting the low-latency and high-throughput requirements, but these approaches are unable to sustain this performance when the data grows larger than DRAM capacity. Existing systems thus achieve these goals either by assuming large enough DRAM (too expensive) or by supporting only a limited set of queries (e.g., key-value stores). In this dissertation, we explore algorithmic and data structure-driven solutions to these system design problems. We present Succinct, a distributed data store that addresses these challenges using a fundamentally new approach --- executing a wide range of queries (e.g., search, random access, range, wildcard) directly on a compressed representation of the input data --- thereby enabling efficient execution of queries on data sizes much larger than DRAM capacity. We then describe BlowFish, a system that builds on Succinct to enable a dynamic storage-performance tradeoff in data stores, providing applications the flexibility to modify the storage and performance fractionally, just enough to meet the desired goals. Finally, we explore approaches that enable even richer query semantics on compressed data, including graph queries using ZipG, a memory efficient graph store, and regular expression queries using Sprint, a query rewriting technique.
HE USE OF SOME ORGANIC AND BIO-FERTILIZERS FOR EARLIGRANDE PEACH TREES FERTILIZATION UNDER NORTH SINAI CONDITIONS b: Fruiting and fruit quality

This study aimed to examine the effect of organic sources such as fish scrap, goat manure and olive pomace, type of application (surface and trench) and bio-fertilizer applications (Nitrobein or Rhizobacterein) on flowering, fruit yield and fruit quality of Earligrande peach trees during the two consecutive seasons of 2013/2014 and 2014/2015 at the private Farm at El-Kharafen village in Rafah district, North Sinai Governorate, Egypt. Results indicated that organic fertilization treatments increased number of flowers per shoot, fruit set percentage, total yield, fruit volume and firmness, Vitamin C and total soluble solids (TSS) in both seasons. The fish scrap treatment produced the highest value of each yield measurement, followed by goat manure treatment, then olive pomace treatment compared with nonfertilized trees (control). On the other hand, trench application achieved very significant effect on tree yield (Kg/tree), fruit weight, fruit volume and firmness compared with surface application in both seasons, But surface application recorded the highest value for each of Vitamin C and total soluble solids (TSS). Also, results showed that Rhizobacterein fertilizer recorded the heights value for each of fruit weight, fruit volume and firmness, Vitamin C and total soluble solids (TSS). Finally, additive the fish scrap (about 2.77 Kg. tree. Year) with Rhizobacterein fertilizer (50 g/tree) in trench application gave the highest fruit properties, fruit yield and improve "Earligrande" peach fruit quality properties in the same experiment conditions.
Genetic analysis of grain dimensions and weight and their association with grain yield in rainfed rice (Oryza sativa)

An experiment was conducted during rainy season of 1991 to stud the inheritance of grain size, shape and weight and their interrelationships with grain yield in rainfed rice (Oryza sativa L), Grain length, breadth and shape were found quantitatively inherited and their expression was influenced by modifiers in 5 intervarietal crosses, viz 'RR 51-1' x 'Kalinga 3','BG 367-4' X 'RR 149·177', 'BO 367-4' X 'RR 203-2', Annada' x 'Kalinga 3' and' Annada' X 'Prasanna'. The frequency distribution for grain weight in the F2 generation of 'BG 367-4' x 'RR 149-177' and 'Annada' X 'Kalinga 3' indicated the segregation of genes of major effect, whereas in the rest of the 3 crosses the expression of grain weight was under polygenic control. High heritability (broad sense) along with high to mooerate expected genetic advance for grain weight, grain length, breadth and shape indicated that selection in the segregating generation might be very useful in the improvement of these characters. There was no consistent trend of interrelationship among grain size, shape, weight and yield.
Progresso genético do rebanho Gir leiteiro de umbuzeiro, PB

Genetic progress was evaluated in a milking Gyr herd in Umbuzeiro, Paraiba, Brazil. Data from 1,049 lactations of 329 cows mated to 32 bulls were analysed by least squares and maximum likelihood methods. It was observed significative influence (P <0,01) of year and month of calving on the lactation length and milk yield. The best lactations length and milk yields were observed for cows that calved from October to April, mainly for cows that calved in February (yield of 1,542 ± 69 kg/year and lactation length of 241 ± 8 days). Repeatability estimates for lactation length and milk yield were 0.37 ± 0.04 and 0.57 ± 0.03, respectively. In same order, heritability coefficients (paternal half-sibs correlation method) were 0.023 ± 0.043 and 0.37 ± 0.13). Genetic and phenotypic correlations between these characteristics were 0.903 ± 0.022 and 0.807. Annual genetic and phenotypic trends were 0.53 and 3.4 days for lactation length and 6.55 and 30.55 kg for milk yield. Modest genetic gain obtained for milk yield (0.52% in relation to overall mean per year) suggests the necessity of increase in the selection pressure for yield, in the herd studied.
A Palynotaxonomic Study of Euphorbia Section Zygophyllidium (Euphorbiaceae)

Using light and scanning electron microscopy morphological studies of pollens were conducted to determine the sectional boundary and the relationships among eight species of section Zygophyllidium and its five related species of subg. Poinsettia. Pollen characters of 13 species were described, and their diagnostic keys were presented here. Based on the sculpturing patterns and the results of numerical analysis using 10 pollen characters 13 species were divided into four Pollen types: type I, having micro-reticulate shaped pollen (E. hexagona, E. lagunensis, E. hexagonoides and E. bilobata), type II, having reticulate shaped pollen (E. delicatula, E. extipulata, E. dentata, E. heterophylla, E. pulcherrima and E. cyathophora), type III, micro-reticulate shaped pollen with platten muri (E. lacera), and type IV, haying foveolate shaped pollen grains (E. chersonesa and E. eriantha). The results of pollen morphological studies suggest that the sect. Zygophyllidium should be delimited based on only four species, E. hexagona, E. lagunensis, E. hexagonoides and E. bilobata, E. delicatural and E. exstipulata of sect. Zygophyllidium must be transferred to subg. Poinsettia based on pollen morphology. E. eriantha and E. chersonesa having forveolate sculpturing pattern of pollen grains seem to be closely related with species from subg. Agaloma, and additional studies of these species are needed to determine the species relationships within Agaloma group.
Investigating the roles of the cell wall anchoring sortase enzyme and sorted proteins in Clostridium difficile

Clostridium difficile is a Gram-positive, anaerobic bacterium that is the most frequent cause of antibiotic-associated colitis and healthcare-acquired diarrhoea worldwide. In many Gram-positive bacteria, a membrane bound sortase enzyme covalently anchors surface proteins to the cell wall, a process that is essential for virulence. Sortase protein anchoring is mediated by a conserved cell wall sorting signal on the anchored protein, containing the “LPXTG-like” motif. Sequence analysis confirmed that C. difficile strain 630 encodes a single sortase, CD2718, but little is known about its function. In this study, we identify seven predicted cell wall proteins with the (S/P)PXTG sorting motif, four of which are conserved across all five C. difficile lineages and include potential adhesins and cell wall hydrolases. A FRET-based assay was developed to confirm that recombinant CD2718 catalyses the cleavage of fluorescently labelled peptides containing (S/P)PXTG motifs in vitro. Mass spectrometry reveals the cleavage site to be between the threonine and glycine residues of the (S/P)PXTG peptide. Replacement of the predicted catalytic cysteine residue at position 209 with alanine abolishes CD2718 activity, as does addition of the cysteine protease inhibitor MTSET to the reaction. The activity of CD2718 can also be inhibited by several small-molecule inhibitors identified through an in silico screen. CD2718-mediated cleavage of a recombinant fusion protein containing the full length predicted sortase substrate CD0183 was also observed. These results demonstrate for the first time that C. difficile encodes a single sortase enzyme that recognises (S/P)PXTG sequences. The activity of CD2718 can be inhibited by rationally designed small-molecule inhibitors, and may be an appropriate target for downstream anti-infective therapies against C. difficile infection.
Weed suppressing ability of some monoterpenes

Monoterpenes are the simple chemical constituents of volatile essential oils found in a number of aromatic plants. Being biologically active they provide the donor plants a number of characteristics. These are also known to play an important role in allelopathy as evidenced from the sparse vegetation around the donor plants. A study was under-taken to explore the effect of some monoterpenes viz. citronellol, citronellal and linalool for their inhibitory effect towards two weedy species viz. Echinochloa crus-galli and Bidens pilosa. Germination and growth of test weed species measured in terms of seedling length and dry weight were drastically reduced in response to the treatment of monoterpenes. Not only growth even the content of chlorophyll was also found to be less in the treated plants compared to control. These observations suggest that monoterpenes affect the photosynthetic machinery of the treated plants. Eight-week-old plants of E. crus-galli were completely killed with 2 ml spray treatment of 400 mM of citronellol. Monoterpenes also caused a rapid electrolyte leakage in the cotyledons of Cassia occidentalis thereby depicting a severe effect on the membrane integrity. The study, therefore, concludes that monoterpenes being chemically the simpler compounds can be utilized for the purpose of managing noxious weeds either directly as bioherbicides or indirectly by serving as template for the synthesis of new herbicides.
Palatability and consumption of patty-formulated pollen and pollen substitutes and their effects on honeybee colony performance

Honeybee health is of grave concern to the apicultural industry and to agriculture generally. The quality of diet influences colony health and strength, especially for colonies preparing for overwintering or starting population build-up in early spring. The palatability of four feeds to honeybees and their effects on colony performance were assessed by three independent feeding experiments made in late fall and early spring with experimental and commercial honeybee colonies in southern Ontario, Canada. The colonies were supplied with patties of bee-collected pollen, Bee-Pro®, TLS Bee food, or Feedbee® or no supplementary feed as the control. The first trial in late fall 2003 used 21 equalized experimental colonies receiving Feedbee®, pollen, or Bee-Pro® for 33 days. The feed consumption for Feedbee® and pollen were both higher than for Bee-Pro®. The second trial used 24 equalized experimental colonies in early spring 2004 for 30 days. Then, feed consumption for Feedbee® and pollen were again both higher than for Bee-Pro®. Also measured in these trials were capped brood area, bee population, and honey production. Results for all three response variables were similar between Feedbee® and pollen, and significantly higher than Bee-Pro® and controls. The third trial used 33 commercially operated colonies (in 2 independent apiaries) that received Feedbee®, Bee-Pro® and TLS Bee food in fall 2004 for 30 days. The results showed Feedbee® had greater consumption than the other two feeds. In all three experiments and for all parameters there were no significant differences between feeding Feedbee® and pollen. The results indicate the potential of Feedbee® for improving colony maintenance and health, build up and production during a shortage or absence of natural pollen.
Zvvei neue Harpacticoida (Copepoda) aus dem Westnorwegischen Kdstengebiet

Abstract Two new species of harpacticoid copepods are described, belonging to the families Paramesochridae Lang and Ancorabolidae Sars. They were collected from muddy substratum at depths of 515 and 680 metres respectively in Korsfjorden in western Norway. Leptopsyllus elongatus sp. n. differs from other Leptopsyllus species in body size, structure of P.5, mouth parts, exopodite of antenna, and its occurrence in muddy substratum. Dorsiceratus octocornis gen. et sp. n. is referred to a new genus on account of the presence of chitinous spines on the cephalothorax and on the first three thoracic segments.
Plasmodium falciparum : mechanisms that reduce transmission to mosquitoes

The standard laboratory test for reduction in malaria transmission is based on the measurement of oocyst numbers in mosquitoes fed on blood meals containing test and control sera. Interpretation of the results, however, is often hampered by the large variation in numbers of infected mosquitoes and oocysts. The objective of this study was to compare 3 measures for the assessment of transmission reduction (so-called R values) and to define the experimental criteria that allow interpretation of the results. To determine variability in R values of control sera, a replicate experiment was performed with 10 non-endemic sera of Dutch blood donors. Furthermore, 2 measures for calculation of transmission reduction were compared in a triplicate experiment using, Plasmodium falciparum, Anopheles gambiae and malaria endemic sera. Calculations using the geometric means of Williams are currently used to identify blocking and non-blocking sera. However, calculations using log-transformed data could distinguish more gradual levels of transmission reduction activity in endemic sera-i.e. blocking, reducing and non­ blocking activity. Grading of transmission reduction activity is important for epidemiological studies on transmission immunity and for validation of future transmission-blocking vaccines.
Flexible support and enhanced groove geometries for gas lubricated bearings

Gas lubricated Herringbone-Grooved Journal Bearings (HGJB) are a promising solution to support high-speed rotors in oil-free turbo-machinery due to their compactness, relatively low losses, no need for lubrication and low wear. Gas lubricated bearings, however, generally require very small clearance to diameter ratios to allow stable rotor operation. The consequences are high manufacturing cost, stringent misalignment tolerances and increased specific windage losses. Increasing the bearing clearance while maintaining the performance of the rotor-bearing-system allows to significantly reduce these shortcomings and would help to make the application of HGJBs in products less challenging. Two approaches have been investigated that allow an increase in bearing clearance while maintaining the rotordynamic stability of the system: (1) a flexible support structure for HGJB bushings and (2) enhanced groove geometries. Both approaches suggest a 50% increase in bearing clearance. A dedicated test-rig was designed to allow the experimental characterization of stiffness and damping of various O-Ring geometries and installation specifications. In a first stage, a Design of Experiments approach enabled the identification of the governing variables on the stiffness and damping of O-Rings. The measurement results of 60 representative O-Ring geometries then allowed the development of data-driven, reduced-order models for the stiffness and damping of O-Rings as a function of the excitation frequency, rubber hardness, O-Ring geometry and squeeze. A generic flexible bearing bushing support for HGJBs has been developed to address the shortcomings of the commonly used O-Rings to flexibly support the bearing bushings. The novel flexible support is based on membrane shaped disks featuring specific cut-outs, resulting in an independently tunable support stiffness. An alignment procedure has been presented that is able to perform the very challenging task of aligning two bearing bushings separated by a considerable distance. The novel flexible support has been successfully implemented in a base-line prototype and aligned with the presented alignment concept, which showed significantly improved repeatability, lower lift-off speeds and less wear compared to O-Ring supported bearing bushings. An experimental campaign was conducted to verify the theoretically predicted potential of enhanced groove geometries to increase the bearing clearance of HGJBs. Good agreement between experimentally determined speed of instability onset and
Parental work demands and the frequency of child-related routine and interactive activities

This study examined whether the frequency of child-related activities was associated with parents' own work demands and those of their partners. In addition to parental paid working hours, we considered the parents' organizational culture and experienced job insecurity. Moreover, we differentiated between child-related routine and interactive activities. Using self-collected data on 639 Dutch couples with children, we found that paid working hours were consistently associated with a lower frequency of child-related activities. Fathers generally responded more strongly to their own and their partner's work demands than mothers. For fathers, both their own and their partner's work demands were more strongly associated with routine than with interactive activities. Mothers did not differentiate between these activities, however.
Aquepts of Indo-Gangetic Plain of Bihar and their Suitability for Some Major Crops

Six pedons, typical of the different kinds of Aquepts occurring in Indo-Gangetic Plain of Bihar were studied to characterize, classify aud evaluate their suitability for crop production. The soils, in general, were deep, imperfectly drained to poorly drained, greyish in colour with redoximorphic features, variable in texture, neutral to slightly alkaline in reaction, low to medium in CEC with low content of organic carbon. These soils were classified as Aerie Epiaquepts, Vertic Epiaquepts and Typic Epiaquepts. The major limitations of these soils were impeded drainage, slow to very slow permeability, moderate to severe flooding hazards and low fertility. Soil-site suitability evaluation revealed that these soils were moderately to marginally suitable for cultivation of rice and major soils were marginally suitable for wheat and unsuitable for cultivation of sugarcane.
From English language learners to intercultural citizens: Chinese student sojourners’ development of intercultural citizenship in ELT and EMI programmes

The notion of global or intercultural citizenship has become prominent in international higher education and English medium instruction. The goal is to educate students for successful interaction in intercultural situations across multiple communities from the local to the global. However, most discussions are at the theoretical level and there is insufficient empirical evidence documenting the extent to which experiences of students in international universities actually leads to the development of intercultural citizenship. To address this gap this research explored the experiences of Chinese students (the largest group of international students in the UK and a major group of English language teaching learners) before, during and after study abroad. Data was collected from students (n = 258) via questionnaires, interviews and a focus group in the UK and China. Findings demonstrated generally positive attitudes towards intercultural citizenship and intercultural citizenship education. Furthermore, many participants reported developing an increased sense of identification with intercultural citizenship as a result of study abroad. However, understanding of intercultural citizenship was often superficial and no students reported any formal intercultural citizenship education either in preparation for study abroad or during their time in the UK. Moreover, a number of students either rejected or withdrew from the idea of developing an intercultural identity due to negative impressions of intercultural experiences. We argue that these mixed findings are unsurprising given the lack of opportunities to prepare for or reflect on intercultural experiences. Furthermore, the absence of intercultural citizenship education is a missed opportunity in English language teaching and English for academic provision.
