Published: November 2018

This study was conducted to know prevalence of gestational diabetes and associated factors. A cross sectional data was collected from the pregnant mothers from a hospital of Barisal city, Bangladesh. It was revealed that 5% of the interviewed mothers suffer from diabetes. Among 100 participants, 58% were in 20-30 years age group and 68% patients married within 21-25 years old. Near about half (51%) of mothers had more than 60 Kg body weight. Maximum (48%) patients passed their secondary education and 78% were jobless. More than half (56%) of the patient’s family monthly earned 10000-20000 BD Tk. Among the mothers, 15% had the family history of diabetes. Correlation matrix revealed that, body weight, and blood pressure were positively associated with sugar level. Gestational age (P=0.04261) and diastolic blood pressure (P=0.018764) were significantly associated with the RBS of pregnant mothers. More study should be conducted to explore the accurate prevalence and practices of diabetic patients in the study area.Asian J. Med. Biol. Res. September 2018, 4(3): 274-278
Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?
Authors: Bialy Shmuel , Loeb Abraham
Published: November 2018

‘Oumuamua (1I/2017 U1) is the first object of interstellar origin observed in the solar system. Recently, Micheli et al. reported that ‘Oumuamua showed deviations from a Keplerian orbit at a high statistical significance. The observed trajectory is best explained by an excess radial acceleration Δa ∝ r
−2, where r is the distance of ‘Oumuamua from the Sun. Such an acceleration is naturally expected for comets, driven by the evaporating material. However, recent observational and theoretical studies imply that ‘Oumuamua is not an active comet. We explore the possibility that the excess acceleration results from solar radiation pressure. The required mass-to-area ratio is (m/A) ≈ 0.1 g cm−2. For a thin sheet this requires a thickness of ≈0.3–0.9 mm. We find that although extremely thin, such an object would survive interstellar travel over Galactic distances of ∼5 kpc, withstanding collisions with gas and dust grains as well as stresses from rotation and tidal forces. We discuss the possible origins of such an object. Our general results apply to any light probes designed for interstellar travel.
Sarracenia carnivorous plants cannot serve as efficient biological control of the invasive hornet Vespa velutina nigrithorax in Europe
Authors: Wycke Marie-Anne , Perrocheau Romaric , Darrouzet Eric
Published: November 2018

Vespavelutinanigrithorax, an invasive species, a direct result of increased trade and climate change, is spreading rapidly in Europe and endangering entomofauna in general and more alarmingly honeybee (Apismellifera) populations, and therefore their pollination services. All traps used now, to try to control this species, seem to be not efficient enough and non-selective. However, in the current context of massive disappearance of insects in general, it is urgent to find means of protection for the entomofauna. While no selective trapping is still occurring, we performed a pilot study to test a carnivorous plant as a potential biocontrol tool to trap V.velutina. In our study, we analyzed the hornet-capturing ability of two Sarracenia hybrids (S.juthatipsoper and S.evendine) on a 2-years period (2015 and 2016). Our results show that these plants trapped more dipterans than other taxa, and they do not attract many hornets. In such condition, both Sarracenia hybrids cannot therefore be used in a mass trapping system, because they are not selective, and too few hornets are trapped. To maximize captures of V.velutina while minimizing captures of non-target species, other systems need to be thus developed, as traps using hornet pheromone-based baiting.
Commerçants indépendants à Paris : l’atout de la proximité ?
Authors: Bouchareb Rachid
Published: November 2018

Rester commerçant indépendant dans une grande ville comme Paris s’avère toujours plus difficile quand la proximité urbaine et la sociabilité s’atténuent du fait de pratiques de consommation tenant plus à la renommée marchande du lieu et à la façade des boutiques. Plus nombreux dans le sud de la capitale qu’au sein des beaux quartiers, les petits commerçants et artisans préservent péniblement des métiers tant leur savoir-faire perd de son prestige urbain. Alors qu’une logique associative vise à fédérer les commerçants autour de la proximité comme enjeu du service rendu au client, c’est cependant une logique individuelle qui prévaut tant les situations commerçantes varient selon leurs stratégies et les espaces commerçants. La proximité peut tout à la fois représenter un atout et une contrainte lorsque le commerçant en dépend fortement.
La soft law européenne dans la mise sur agenda nationale
Authors: Bérut Chloé , Saurugger Sabine
Published: November 2018

Resume Au sein de l'Union européenne, le secteur de la santé, et particulièrement celui de l'organisation des soins médicaux, est encore aujourd'hui considéré comme une prérogative étatique. Afin d'engager une harmonisation de cet aspect de la politique de santé, l'Union européenne (UE), et plus particulièrement la Commission européenne, a mis en place une série de mesures non juridiquement contraignantes ( soft law ) dans le domaine de l'e-santé. Cet article s'interroge sur la capacité de ces mécanismes de soft law à influencer la mise à l'agenda de politiques nationales dans un domaine où les traités ne lui donnent pas de compétences. Nous comparons ainsi deux cas, la France et le Royaume-Uni, qui adoptent des technologies d'e-santé alors même que le processus de mise à l'agenda de ces politiques diverge. Au centre de cette analyse se trouveront les acteurs nationaux, leurs intérêts, leurs stratégies et les usages qu'ils choisissent (ou non) de faire du niveau européen.
Gouverner par la conditionnalité ou la flexibilité ?
Authors: Coman Ramona , Sbaraglia Fanny
Published: November 2018

Resume La crise de la zone euro a induit une redéfinition profonde de la gouvernance économique de l’Union européenne afin de renforcer les règles du Pacte de stabilité et de croissance (PSC). L’article analyse comment ces idées, initialement conçues pour renforcer la gouvernance économique, ont également eu des effets sur la politique de cohésion et ont façonné l’adoption du règlement 1303/2013 sur les fonds structurels et d’investissements européens (fonds ESI). En examinant les rapports de force entre le Parlement, la Commission et le Conseil, l’article montre comment la conditionnalité s’est imposée comme idée dominante entre 2010 et 2013 et comment, après 2013, les mécanismes de sanction imposés pendant la crise divisent les institutions entre les partisans de l’application stricte des règles et ceux favorables à une plus grande flexibilité dans leur mise en oeuvre.
Micropolitiques pour le droit à la ville au Brésil : tissages d’un mouvement social mineur
Authors: Brum Schäppi Paula
Published: November 2018

L’article propose une réflexion sur l’activisme contemporain et ses tissages micropolitiques pour le droit à la ville au Brésil. Il analyse les manières dont le mouvement anti-asilaire ( antimanicomial ) de Rio de Janeiro aborde et problématise cette question. À travers des résistances, des affirmations et des expérimentations, ce mouvement social mineur investit la ville comme lieu de care en santé mentale et de soin avec le commun. L’article explore des pratiques et discours militants qui pensent et occupent l’espace urbain en tant qu’espace politique, de circulation et de prise en compte de la différence, en particulier de la folie. En mettant l’accent sur les micropolitiques engendrées par des mouvements sociaux mineurs, il est possible d’envisager des processus à contre-courant du triste scénario de rupture démocratique sous couvert de légalité que la macropolitique brésilienne traverse à présent.
Facteurs influençant la répartition modale du transport de marchandises en Tunisie
Authors: Bouguerra Hajera , Souissi Besma , Benammou Salwa
Published: November 2018

Afin de comprendre les raisons qui poussent les opérateurs tunisiens à recourir au transport routier de marchandises et non pas au rail, une enquête auprès de 100 entreprises situées dans la région du Sahel a été effectuée. Le principal résultat de cette recherche est que l’idée d’un transfert modal de la route vers le chemin de fer a suscité plusieurs oppositions. Ce refus est expliqué essentiellement par l’image négative du rail et la négligence des problèmes environnementaux par la plupart des utilisateurs.
Dualité gouvernementale et reconnaissance internationale. Les délégations turques à la Conférence interalliée de Londres en 1921
Authors: Le Bras Claire
Published: November 2018

La Conférence interalliée qui se réunit à Londres du 21 février au 12 mars 1921 avait pour objectif l’étude de la question orientale et la cessation des hostilités gréco-turques en Anatolie. Par la convocation de toutes les parties intéressées, elle donna lieu à un conflit de légitimité entre les gouvernements de Constantinople et d’Ankara, en concurrence pour représenter la Turquie sur la scène internationale. Interrogeant les circonstances qui conduisirent à la présence de deux délégations turques devant la Conférence interalliée, cet article examine les enjeux et les manifestations de cette rivalité pour la reconnaissance internationale, ainsi que la prise en compte par le système international de la dualité gouvernementale en Turquie.
Une République isolée. L’Espagne face aux interventions fascistes durant la guerre civile
Authors: Viñas Ángel
Published: November 2018

Cet article s’inspire des dernières recherches menées en Espagne sur les rapports entre la guerre d’Espagne et le système international des années trente, à propos notamment de l’intervention italienne quinze jours avant le coup d’État. Il est aussi prouvé que le Royaume-Uni a bel et bien été le mauvais génie de la non-intervention : il a vu dans l’explosion d’un vaste mouvement social en Espagne la confirmation de ses craintes concernant la possibilité d’une révolution de type soviétique sur le continent. Avec la France, il a pesé de tout son poids sur la Société des Nations pour éviter l’application d’un système de sécurité collective ancré dans le Pacte fondateur de l’organisation. Dès lors, face aux interventions nazie et fasciste tout au long de la guerre, seule l’Union Soviétique pouvait sauver la République. En oubliant les entorses à la politique de non-intervention, le système international tel qu’il a fonctionné a porté un grave préjudice à cette dernière en contribuant de manière fondamentale à la victoire de Franco.
Nixon, Kissinger et la guerre civile au Cambodge
Authors: Coppolani Antoine
Published: November 2018

Depuis la victoire des Khmers rouges, plusieurs questions ont fait débat, concernant l’implication des États-Unis dans la guerre civile. Plus précisément, trois accusations n’ont jamais disparu. La première est que la CIA aurait joué un rôle dans le renversement de Norodom Sihanouk en 1970. La deuxième est que « l’invasion » du Cambodge par les Américains (Nixon et Kissinger préféraient parler « d’incursions ») aurait été une désastreuse illustration de la « théorie du fou » chère à Nixon. Enfin, la guerre américaine au Cambodge, et tout particulièrement les campagnes de bombardements de B-52, seraient responsables de la montée en puissance des Khmers rouges, de la chute de Phnom Penh, le 17 avril 1975, et du bain de sang qui s’ensuivit des années durant. S’appuyant sur les archives désormais disponibles et prenant en compte plusieurs décennies de recherches d’auteurs variés, cet article s’efforce de dissiper certains mythes sur le rôle des États-Unis dans la guerre civile au Cambodge.
L’écho des persécutions. Les minorités nationales, la Conférence de la Paix et les guerres civiles à l’Est de l’Europe (1919-1920)
Authors: Chopard Thomas
Published: November 2018

Cet article analyse deux phénomènes parallèles et en apparence contradictoires qui se déploient au sortir de la Première Guerre mondiale : la multiplication des persécutions et des discriminations contre les minorités nationales à l’est de l’Europe et la façon dont la « question des minorités » s’est imposée dans les débats publics et diplomatiques, tout particulièrement à la Conférence de la Paix de Paris qui s’ouvre en 1919. Tandis que se met en place au sein de la Société des Nations un nouvel ordre international supposément garant des droits des minorités, les alertes et les protestations des représentants des minorités persécutées sont en réalité minorées et rendues inopérantes. Loin d’opposer le droit international protecteur et la force des États nationalistes, l’article conclut à une compatibilité des deux, notamment en raison de l’attitude décisive des grandes puissances occidentales.
Logiques de pratiques de slackline
Authors: Chavaroche Lionel
Published: November 2018

Aujourd’hui les disciplines qui gravitent autour du Slackline sont multiples. Shortline, Highline, Jumpline et autres hybridations. Les milieux d’évolution oscillent entre parcs urbains, pratique indoor ou encore réappropriation d’un espace sauvage. L’utilisation de la sangle est aussi variable, pouvant faire de la discipline une activité individuelle de concentration, de partage ou encore de spectacle. Un questionnaire complété par une enquête ethnographique nous ont permis de regrouper ces façons de pratiquer autour de trois grandes logiques pouvant être complémentaires. Celles-ci nous apportent un éclairage pour mieux appréhender les loisirs actuels qui tendent à dépasser un temps particuliers pour s’inscrire dans un mode de vie.
The knowledge, perceptions and relationship behaviour of rugby and football players towards HIV infection at the University of Limpopo
Authors: Govender Indiran , Nel Kathryn , Banyini Nhlanhla
Published: November 2018

Background: Sport has the capability to unite a country. To achieve winning teams, athletes have to rely on each other and often have close physical contact. Disclosure of a positive human immunodeficiency virus (HIV) status may be problematic for athletes in contact sports as they may suffer discrimination and stigmatisation which may impact their relationship behaviours. This may impact frontline nursing and medical staff dealing with on-field ‘blood’ injuries.Objectives: The purpose of this study was to determine if individuals who participate in football and rugby are aware of the risk of HIV infection in contact sports and their perceptions and reported behaviour towards HIV-positive athletes.Method: A cross-sectional survey design with a qualitative element. Quantitative data were analysed using descriptive statistics, while thematic content analysis was used to analyse qualitative data.Non-proportional quota sampling was used for male rugby (n = 23) and football (30) players registered at the University of Limpopo (Turfloop campus).Results: The results supported previous research in that there are gaps in HIV knowledge. For instance, not knowing that anal sex may cause HIV infection and believing that saliva can transmit HIV and that blood transfusions are unsafe.Conclusion: Problematic findings were that a portion of the sample believed that having sex with a virgin could cure HIV and the majority of the sample believed that being ‘bewitched’ could cause HIV and acquired immunodeficiency syndrome (AIDS).

Deposition of Pesticide to the Soil and Plant Retention During Crop Spraying: The Art State
Authors: Allagui Asma , Bahrouni Hassouna , M’Sadak Youssef
Published: November 2018

Environment pollution related to pesticides has been confirmed by the scientific community for a long time, but the available information on the impact of this phenomenon on human health and the ecosystem are still insufficient. Contamination of the environment can occur through various pathways, ground deposits during the application of pesticides to crops are one of those pathways. The retention rate of sprayed droplets is an important factor both for the efficacy of the phytosanitary treatment and the quantities of lost pesticides on the ground. This paper presents an overview of factors that affect spray droplet behavior, involved process in sprayed drop fate and the mainly techniques for measuring pesticide deposits to the ground and plant retention. We present studies that have focused on pesticide retention and soil deposition during crop spraying in relation to sprayer equipment, used formulation and climatic factors. Plant retention and pesticide deposits during spray is a complex problem depending mainly on physical sprayer parameters, climatic conditions, spray properties and chemical formulation. By illustrating the large variety of analytical methods during the recently years, it aims to explain that it is always possible to assess the impact of pesticides in all compartments of the environment. The use of concerned molecules and natural collectors is the safest to evaluate the real situation, but the use of tracers and artificial targets is both very reported and safety for the environment.

Published: November 2018

In Brazil the Caatinga biome is formed by endemic species with numerous applications in medicine, cosmetics and agrochemicals. However, only 8% of the country’s plant species are chemically evaluated annually. Thus, the work aimed to determine the free amino acid composition and phenolic substances of Caatinga plant species extracts, their antioxidant activity and the potential use of these compounds in the control of A. alternata in citrus. Leaf extracts from fourteen native plant species were evaluated for free amino acid contents; total and individual polyphenols; total flavonoids and antifungal susceptibility test. The relationship between the contents of the compounds detected in each plant extract with its antioxidant capacity and antifungal activity, has not yet been fully clarified. However, it is a fact that the extract of Cleome hassleriana constitutes a source rich in free amino acids. It is also verified that the extracts of Mimosa tenuiflora and Caesalpinia ferrea are efficient alternatives in the control of Alternaria alternata in citrus, because they present similar results for this purpose, and in the evaluation of their compositions in free amino acids, phenolic substances and antioxidant activity.

Among the nutritional requirements of corn crop, nitrogen (N) is the element required in greater quantity and, directly responsible for increase or decrease in grain production. The aims of study were to evaluate the effects of applied N rates in topdressing in development and production of corn in Brazilian Amazon. The experiments were installed on 20 January 2014 (Capitão Poço city) and 24 January 2014 (Paragominas city). The experimental design was a randomized block design in a 5 × 2 factorial scheme, consisting of five N rates of topdressing applications (0; 40; 80; 120; and 160 kg ha-1 of N) and two corn double hybrids (AL-Avaré; and AL-Bandeirante), with four replicates. The evaluations of vegetative development components (plant height, height of ear insertion, and leaf area index) were carried out at time of male flowering stage, while evaluations of grain yield components (number of grains per row, grain yield, and harvest index) carried out during the harvest period. The corn hybrids, AL-Avaré and AL-Bandeirante, independent of experimental site, showed the highest technical efficiency between the rates of 80 to 120 kg ha-1 of N. Based on the information obtained in regression analysis verified that Paragominas experiment showed greater vegetative development (plant height, LAI, ear height, number of grains per row, ear length) and higher grain yield compared to corn developed in Capitão Poço experiment.

The efficiency of family farmers irrigation is conditioned by several factors such as good quality water supply. In this context, it was to evaluate the salinity and physical, chemical, and bacteriological characteristics of water harvested from roofs for irrigation of crops by family farmers in Brazil. The experiment was conducted at the Federal Institute Goiano, in Rio Verde, Goiás, Brazil. The rainwater collected on the roofs was sent through vertical and horizontal conductors to the storage tank, which has a capacity of 5000 L. The risk of salinity, pH, turbidity, conductivity, color, total dissolved solids and thermotolerant coliforms during 13 precipitation events was analyzed. Rainwater was classified as water with no salinity problem (EC < 0.7). The variation of the electrical conductivity (EC) and Total Dissolved Solids (TDS) were similar during the collection period, with mean values of 0.05 dS m-1 and 29.72 mg L-1 for EC and TDS, respectively. The pH of the rainwater presented little variation, presenting a mean of 7.37. The mean value of the color of rainwater was 11.45 PtCo L-1, while the turbidity averaged 4.89 UT. During the period of rainwater harvesting, it was observed absence of thermotolerant coliforms in all samples. It is concluded that rainwater does not present restrictions on the risk of salinity and that all physical-chemical and bacteriological parameters analyzed are within the limits allowed by Resolution 357/2005 of CONAMA, indicating the propensity of this type of water for irrigation.

Sustainable agricultural systems are necessary to improve soybean [Glycine max (L.) Merr.] seed yield and to increase nutrient use efficiency. Intensification of agricultural systems is an important tool to increase farmers’ profitability in the Cerrado region (Brazil), where soybean is rotated with corn in the same growing season. However, this intensification requires soybean cultivar with short growing periods which is achieved by indeterminate soybean cultivars. There is a lack of information regarding the nutrient uptake by soybean cultivars under intensive agricultural systems in the Cerrado. We sought to investigate soybean biomass production and soybean seed yield of determinate and indeterminate soybean cultivars. We also aimed to quantify the amounts of nutrients taken up by soybean biomass and seeds. Field research was conducted to evaluate 17 soybean cultivars commonly grown by farmers, and we considered the determinate and indeterminate soybean growth habit. Nutrient uptake and aboveground soybean biomass were higher under shorter soybean growth and development cycles. Nitrogen, phosphorus and potassium extraction in modern cultivars was higher than in cultivars used in past decades. Nutrient use efficiency was higher in determinate soybean cultivars than in indeterminate soybean cultivars.

The present work had as objective to determine the kinetics of drying of the chili pepper, to adjust different mathematical models to the experimental values as a function of the water content and to characterize the same in it’s in natura form and after the drying in the temperatures of 60, 70 and 80 °C. The samples were weighted periodically until reaching the equilibrium. The mathematical models of Wang and Singh, Henderson and Pabis, Newton, Page and Thompson were adjusted to the experimental data. The best adjustment was determined in relation to the highest values of the coefficient of determination (R2) and Mean Square Deviation (MSD). The obtained results showed that the drying of the pepper is influenced by the temperature of the drying air. It is concluded that the model of Henderson and Pabis was the one that best fit to the experimental data. The increase of the drying temperature promoted a reduction in the time required for the peppers to reach the moisture of the hygroscopic balance. The parameters of acidity, lipids and proteins remained close at the different drying temperatures used, however higher when compared to the samples in natura. It can be noticed that ashes and vitamin C have suffered considerable decrease as the temperature increased, as a result of the chemical transformations that occurred in the peppers due to heat exposure and loss of moisture.

Origanum majorana is a cosmopolitan herb widely known as “marjoram”, which is used in traditional medicine and as family kitchen herb, for culinary purposes. Phytochemical screening was carried out and the antioxidant activity of Origanum majorana (Lamiaceae) hydroethanolic extract and infusion was investigated in this study. The hydroethanolic extract was screened through thin layer chromatography, subjected to spectrophotometry for polyphenols, flavonoids and tannins, as well as to 2,2-diphenyl-1-picrylhydrazyl free radical and iron reducing power assays. Fresh plant infusion was tested for the first time at three different concentrations against oxidative stress biomarkers in erythrocytes from HIV patients undergoing antiretroviral therapy. High antioxidant substance levels, as well as significant decrease in carbonylated protein, GSH and TBARS levels, were recorded, fact that showed the potential of O. majorana as exogenous antioxidant source. Our results indicated that O. majorana has good potential to prevent diseases caused by the overproduction of free radicals, and that it can be used as potential source of natural antioxidant agents.

This paper aims to conduct an energy efficiency study in the tipping system of the unloading platform of a grain storage unit, based on the use of electrical devices to control the operation of the engine. For this purpose, two scenarios were established. The first scenario considers the platform in its current state, with engine start-up performed using a wye-delta switch. In the second scenario, wye-delta start is switched off, and a frequency inverter and a programmable logic controller (PLC) are coupled to control the electric motor. For both scenarios, the consumption of active and reactive energy in the discharge platform was measured, and the costs of the energy consumed were calculated over a period of one year. Finally, the discounted payback was calculated to evaluate the economic feasibility of installing the proposed equipment. The results obtained were as follows: For the current scenario, the energy consumed to tipping one metric ton of grain was 35.44.10-3 kWh; for the proposed scenario with the frequency inverter, the energy was 32.78.10-3 kWh. With an annual projection, the current scenario would consume the equivalent of 10 921.35 kWh, and the proposed scenario, 10 100.81 kWh, generating an annual savings, with the installation of the equipment, of R$721.49; the discounted payback found was approximately 31 years. It can thus be concluded that there is a reduction in electricity consumption from the use of the frequency inverter; however, the time of return of the invested capital is very long, making the proposal economically unfeasible.

Runner bean (Phaseolus coccineus L.) offers a great potential as a grain legume in Africa. However, its productivity is low because no improved short-day varieties are available. The aim of this study was to evaluate advanced short-day runner bean lines for high grain yield, resistance to diseases and suitable for cultivation under tropical conditions. F6.8 recombinant inbred lines developed from crosses between local landraces and high yielding imported variety (White Emergo) were evaluated in 2013 and 2014 in a randomized complete block design with three replicates at Kabete (1860 m.a.s.l.) and Ol Joro-Orok (2300 m.a.s.l.) in Kenya. Four local runner bean landraces were used as checks. Analysis of variance showed that there were significant differences for days to flowering, response to diseases and grain yield among the evaluated lines. Improved lines flowered within 49 to 52 days in 2013 and 34 to 58 days in 2014.The improved lines flowered earlier at Kabete than Ol Joro-Orok and showed a higher degree of resistance (scores 1-3) to the major diseases rust, bean common mosaic virus (BCMV) and powdery mildew. The mean grain yield at Kabete was 4,426 kg ha-1 compared to 6,523 kg ha-1 at Ol Joro-Orok giving an average yield advantage of up to 67% compared with local short-day landraces. The results indicated that new high yielding short-day runner bean varieties with resistance to major diseases and tropical adaptation can be obtained from these lines.

Mineral nutrients have favourable potential in alleviation of salinity problem in plants. Sulfur has specific functions in regulating plant growth, metabolism, enzymatic reactions and osmolyte homeostasis in plants. Hence, an experiment was carried out to explore the role of sulfur in ameliorating salt toxicity in maize by changes in organic and inorganic osmolyte contents. A range of sulfur levels (40, 80 mM) were used to induce salinity tolerance in maize. Various treatments of salinity (25, 75 mM) were applied by using sodium chloride. Results revealed that glycine betaine, proline, total soluble sugars, total soluble proteins and total free amino acids contents were increased by applying salinity while the application of sulfur lowered the proline and increased other studied organic osmolyte contents in all studied maize organs (leaf, shoot, root). The maximum improvement in organic osmolyte contents were found at 40 mM sulfur, however, at 80 mM sulfur proline contents were reduced. Applied salinity increased leaf tissue concentration of Na+ and decreased that of K+, Ca2+, NO3-, PO43-, SO42- leading to a severely declined in K+/Na and Ca2+/Na+ ratio. However, application of sulfur reduced the Na+ contents and improved K+, Ca2+, NO3-, PO43-, SO42-, K+/Na+ and Ca2+/Na+ ratio in the salinity grown plants. Moreover, 40 mM level of sulfur was greatly effective in osmolyte homeostasis at all levels of salinity. This indicated that use of sulfur (40 mM) ameliorated the effect of salinity by changing organic and inorganic osmolyte contents in maize plants.

Isotopic analyses and chromatographic analysis (phenolic compounds and biogenic amines), can be applied to investigate the functional and nutritional quality in different grape juices and wines. These beverages when produced exclusively from grapes contain bioactive compounds. In this way, the isotopic analysis, as well as the determination of phenolic compounds and biogenic amines were performed with the aim of verify the functional quality of juices and wines produced with Vitis vinifera and Vitis labrusca grapes. The samples that were analyzed consisted of four whole juices, two nectars, two V. vinifera wines, and two V. labrusca wines. Regarding the isotopic analyses, only one nectar, among the beverages studied, presented the addition of sugar from C4 plants. Wines from V. vinifera showed the highest content of biogenic amines and phenols; whereas, the highest content of anthocyanins were found in V. labrusca. The levels of biogenic amines and phenolic compounds were variable between samples, and recommendations for consumers should be made considering several conditions, such as physiological state, age, consumption, among others. Anthocyanins and biogenic amines, as well as isotopic analyses, can be applied as tools to measure the quality of grape derived beverages.

Cassava mosaic disease (CMD) caused by Bemisia tabaci is among the major contributors to low cassava yield in Africa and therefore requires instituting control measures. Due to genetic diversity in cassava, only clones with superior agronomic traits, disease resistance and high yield are selected and released to farmers or deployed in breeding program. This study was conducted to evaluate the resistance of cassava half-sib families to CMD. Field trials were conducted at Kenya Agricultural and Livestock Research Organization (KALRO), at Kakamega and Alupe research stations in western Kenya from June 2016 to June 2017. Sixty progenies were compared to that of their five parents by planting cuttings in 4 × 2 meters plots. Data were collected on plant height, number of roots per plant, harvest index, root yield, dry matter content, cassava mosaic disease and whiteflies infestation. Twenty three genotypes had a mean score of 1.0 to CMD, implying that they are resistant. Cassava grown at Alupe was observed to have high number of susceptible genotypes compared to cassava grown at Kakamega, indicating the effect of the environment on the genotypes. Parental genotypes, Kaleso and MM96/4271 presented high number of progenies showing CMD resistance. Genotypes, P4G1 and P2G3 with mean root yield of 31.6 t ha-1 and 30.0 t ha-1 were the highest yielding in term of root yield. A number of half-sib families generated from MM96/4271, Kaleso and MM96/0686 performed well with respect to yield recorded on their respective parents. Evaluation of new cassava varieties under local disease conditions would most likely improve the productivity of cassava through selection of resistant clones.

Understanding genetic variability and mode of gene action for agronomic and yield related traits is important in formulation of effective rice breeding program for genetic enhancement of grain yield. Combining ability analysis and heterosis was conducted to identify yield associated traits from nine male indicas and three female japonicas, together with their 27 F1 hybrids. Four parental lines, including Basmati 370, Basmati 217, K2-54 and Komboka showed good general combining ability in days to 50% flowering, days to maturity, number of tillers plant-1, number of spikelet’s panicle-1, number of panicles plant-1, number of filled grains panicle-1, and grain yield. While the combine K2-9 × Komboka, K2-9 × Basmati 370, K2-54 × Dourado Precoce and K2-54 × Basmati 217 showed specific good for grain yield. The hybrids K2-9 × Basmati 370, K2-8 × Basmati 217, K2-54 × Basmati 217 and K2-9 × Komboka showed 20% excess in standard check variety, suggesting that they could be good breeding donors.

AbstractService-Oriented Architecture (SOA) is a modular approach to software development based on the use of distributed, loose coupling replaceable components equipped with standardized interfaces for interaction over standardized protocols Component interfaces in a service-oriented architecture encapsulate the implementation details (operating system, platform, programming language) from the rest of the components, thereby enabling the combination and reuse of components to build complex distributed software packages, ensuring independence from the platforms and development tools used, facilitating scalability and manageability of the systems being created. In this paper we introduce a Service composition in service oriented architecture, it is present service composition with different approach used for composing services and provided.
