Abstract

The sexual system of Garcinia atroviridis was evaluated regarding the basic structural specialization and reproductive characters under natural conditions. The species is gynodioecious with females (trees producing pistillate flowers), but hermaphrodites (trees producing perfect flowers) co-occurred in the study site.Significant morphological and anatomical variation was found between pure female and hermaphroditic flowers. Hermaphrodites have relatively long-filament flowers and produce abundant fertile pollen grains, whereas the females produce pollenless anthers. They also differ significantly in reproductive characters. Hermaphrodite flowers have more flowers per inflorescence than female flowers, but they gradually drop off before fruit setting. In contrast, female trees had relatively greater ovules per flower, larger fruits and more seeds per fruit than hermaphrodite trees. Moreover, average seed number from female trees was at least 1.7 times higher than that of the hermaphrodite trees. Interestingly, the fruit diameter of hermaphrodites was positively correlated to the number of seeds, whereas it was unrelated in females.

Abstract

[EN] The dielectric properties of virgin polylactide (PLA) and its reinforced composites with different weight amounts of sisal fibres were assessed at broad temperature (from - 130 degrees C to 130 degrees C) and frequency ranges (from 10(-2)-10(7) Hz), before and after being subjected to accelerated hydrothermal ageing. The synergetic effects of both the loading of sisal and hydrothermal ageing were analysed by means of dielectric relaxation spectra. The relaxation time functions were evaluated by the Havriliak-Negami model, substracting the ohmic contribution of conductivity. The intramolecular and intermolecular relaxations were respectively analysed by means of Arrhenius and Vogel-Fulcher-Tammann-Hesse thermal activation models. The addition of fibre increased the number of hydrogen bonds, which incremented the dielectric permittivity and mainly hindered the non-cooperative relaxations of the biocomposites by increasing the activation energy. Hydrothermal ageing enhanced the formation of the crystalline phase at the so-called transcrystalline region along sisal. This fact hindered the movement of the amorphous PLA fraction, and consequently decreased the dielectric permittivity and increased the dynamic fragility. (C) 2017 Elsevier Ltd. All rights reserved.

Abstract

[EN] The eco-design considers the factors to prepare biocomposites under an end-of-life scenario. PLA/sisal biocomposites were obtained from amorphous polylactide and sisal loadings of 10, 20 and 30 wt% with and without coupling agent, and subjected to biodegradation in soil according to standard IS0846. Mass loss, differential scanning calorimetry and size-exclusion chromatography were used for monitoring biodegradation. A statistical factorial analysis based on the molar mass M-n, and crystallinity degree X-c pointed out the relevance and interaction of amount of fibre and use of coupling agent with the time of burial in soil., During the preparation of biocomposites, chain scission provoked a similar reduction of M-n, for coupled and non-coupled biocomposites. The amount of fibre was relevant for the increase of Xc due to the increase of nucleation sites. The coupling agent accelerated the evolution of both factors: reduction of M-n, and the consequent increase of Xc, mainly during biodegradation in soil. Both factors should be balanced to facilitate microbial assimilation of polymer segments, since bacterial digestion is enhanced by chain scission but blocked by the promotion of crystalline fractions.

Abstract

Surat-thani oyster, a big and thin-shell bivalve mollusks, has been registered as Geographical Indicators, GI, as its good taste and delicacy as well as nutritious. Eaten style is raw then there is high risk to face with some disease as oyster is filter feeder. Physical, chemical, microbiological and sensory qualities after the oyster meat treated with the garlic juice at 0, 2 and 3 ml, respectively were monitored. Though initial pH of the control, untreated with garlic juice, was higher compared with the sample treated with 3 ml garlic juice, pH of it (control) was significantly lower (p<0.05) than the sample treated with the juice during storage. The total volatile base (TVB), chemical quality, values of all samples increased when increased storage time but not over 35 mg/100 g sample. During chilled storage, lactic acid content of all samples increased as storage time increased but the sample treated with the juice was higher compared with the control. A thiobarbituric acid reactive substance (TBARS), rancidity indicator, of the control was higher than the sample treated with the juice. K-value (%) of all oyster meats increased however; the lowest value was found in the control at end of storage, 12 days. Ammonia content of all samplesslightly increased during storage. Lactic acid content of the treated sample was higher than control after stored for 12 days. Both mesophilic and lactic acid bacteria of all samples tended to increase during storage. Mesophilic ofcontrol, sample-injected with garlic juice 2 ml and 3 ml increased from 3.89± 0.04 to 6.2±0.04, 3.62±0.18 to 5.89±0.06 and 3.57±0.02 to 6.04±0.10 log CFU/g, respectively at end of storage. Lactic acid bacteria of control andsample-injected with garlic juice 2 ml and 3 ml changed from 1.71±0.02 to 2.94±0.04, 1.79±0.09 to 4.63±0.08 and 1.84±0.04 to 4.82±0.10 log CFU/g, respectively.

Abstract

The influence of the combined exposure to water and temperature on the behaviour of polylactide/sisal biocomposites coupled with maleic acid anhydride was assessed through accelerated hydrothermal ageing. The biocomposites were immersed in water at temperatures from 65 to 85 °C, between the glass transition and cold crystallisation of the PLA matrix. The results showed that the most influent factor for water absorption was the percentage of fibres, followed by the presence of coupling agent, whereas the effect of the temperature was not significant. Deep assessment was devoted to biocomposites subjected to hydrothermal ageing at 85 °C, since it represents the extreme degrading condition. The morphology and crystallinity of the biocomposites were evaluated by means of X-Ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The viscoelastic and thermal performance were assessed by means of dynamic mechanic thermal analysis (DMTA) and thermogravimetry (TGA). The presence of sisal generally diminished the thermal stability of the biocomposites, which was mitigated by the addition of the coupling agent. After composite preparation, the effectiveness of the sisal fibre was improved by the crystallisation of PLA around sisal, which increased the storage modulus and reduced the dampening factor. The presence of the coupling agent strengthened this effect. After hydrothermal ageing, crystallisation was promoted in all biocomposites therefore showing more fragile behaviour evidencing pores and cracks. However, the addition of coupling agent in the formulation of biocomposites contributed in all cases to minimise the effects of hydrothermal ageing.

Abstract

publisher, 藤沢, 特集 アジアにおけるネットワークと遠隔教育 招待論文, In this paper, we first present some proposed extensions based on SIP (Session Initiation Protocol) conference scenarios. We then show how to use such extensions to enhance interactive distance learning (IDL) applications as an example. Our work describes some enhancements of conference scenarios based on SIP. The system architecture to support such scenarios as well as signal flows are presented. Some flow parameters are given, to show real deployment possibility. We have proposed two additional components to enhance conference features: Conference Manager Server (CMS) and Conference Repository (CR). We have deployed these scenarios for SIP based e-learning applications. We have shown some e-learning scenarios when interactive communications are needed, for example, class scheduled learning, class mate group finding. In addition, other rich features can be added, e.g. sharing on-line objects and documents in real-time, virtual interactive white-board, and multimedia recorder. We have proposed the implementation architecture, some main features are described. We discussed for some future challenging works: P2P based SIP may be adopted. Moreover, converging to UCC (Unified Communication and Collaboration), as well as working on multi-platform and multi-devices are concerned. 本稿では、まず、SIP (Session Initiation Protocol) の会議通話向けの拡張を提案した。次に、この拡張の利用例として、enhance interactive distance learning (IDL) アプリケーションにおける利用例を示した。本研究では、会議向けの拡張のため、Conference Manager Server (CMS) と Conference Repository (CR) の２つのコンポーネントの追加を提案し、E ラーニング用のアプリケーションへの適用を検討した。E ラーニングにおいては、受講者間の会話など、インタラクティブなコミュニケーションが必要な場合がある。また、教材のリアルタイム共有、黒板の共有、マルチメディア録音機能の利用も考えられる。本研究では、これらの機能の実装方針を提案した。

Abstract

Recently, latex price has continuously increased, This motivates rubber smallholders in southern Thailand to increase latex productivity. Then, ethylene stimulation has been introduced in tapping systems. Therefore, it needs to be tested before recommendation to the smallholder. An experiment was established at Thepa Research Station, Songkhla province. Rubber clone RRIM 600 (20 year-old) was used in the experiment. The experiment was designed as one-tree-plot design with 20 replicates. There was 6 treatments: 1) 1/3S­ 2d/3 (C), 2) 1/8S­ 1d/3, 3)1/8S­ 1d/3 + RRIMFLOW (RF), 4)1/8S­ 1d/3 + LET (LET), 5) 1/8S­ 1d/3 + Double Tex (DT) and 6) 1/8S­ 1d/3 + Ethyphon 5% (E). The experimental period was during June 2010 to February 2011. It was found that the RF treatment provided the highest rubber productivity (137.7 g/tree/tapping and 5.9 kg/tree/year), and it was significantly different from the remaining treatments. According to latex diagnosis, sucrose in the RF treatment trended to decrease, but inorganic phosphate and thiol trended to increase.

Abstract

The effect of lipids on antioxidant activities of tested antioxidants and the galangal seasoning, Tom-Kha paste extract were determined. The result showed that heating caused a decrease of DPPH scavenging activity of lauric acid but did not affected on ABTS scavenging activity of both lauric acid and virgin coconut oil. However, ABTS scavenging activity of p-hydroxycinnamic acid and the paste extract in both lauric acid and virgin coconut oil systems increased after thermal processing. In the system of lauric acid, peroxide value (PV) of almost mixtures was increased (p<0.05) by heating. Thiobarbituric acid reactive substances (TBARS) of the mixtures were not significantly different (p<0.05) after thermal processing while p-anisidine value (AV) of only lauric acid-gallic was enhanced after heating. The results showed that PV of virgin coconut oil added with all tested antioxidant was not changed after heating. TBARS of virgin coconut oil added with antioxidant samples seemed to slightly increase after heating. AV of virgin coconut oil with added gallic acid and the paste extract were not changed while AV of virgin coconut oil with added p-hydroxycinnamic acid and Trolox seemed to decrease after heating

Abstract

Ethanolic and water extracts from six species of Indian medicinal plants mainly distributed in the region of Western Ghats, India such as Morinda citrifolia (leaf), Garcinia indica (leaf), Garcinia cambogia (leaf), Salacia oblonga (leaf), Coccinium fenestratum (stem bark) and Calophyllum inophyllum (bark) were tested for their inhibitory activities against two prime enzymes of HIV which are HIV-1 protease (HIV-PR) and HIV-1 integrase (HIV-IN). The results revealed that the ethanolic and water extract of the bark extract of Calophyllum inophyllum exhibited potent anti-HIV-IN activity with IC50 values of 9.8 and 5.6 μg/ml, respectively. Whereas those for anti-HIV-1 PR effect were found to be 63.8 and 16.3 μg/ml, respectively. This result strongly supports the basis for the use of C. inophyllum for AIDS treatment by local traditional practitioners of Ayurveda and Unani system of Indian medicine and it is the first report on HIV-1 Protease and HIV-1 Integrase enzyme inhibition by this plant extract.

Abstract

International audience; Rubber tree plantations (Hevea brasiliensis) cover large areas in the tropics. In historical producing regions like South Thailand, rubber has been planted by smallholders for three successive rotations lasting a total of 75 years. Despite possible consequences on topsoil, the long-term impacts of repeated rubber plantations on soil quality remain unknown. This study aims to better understand how various factors linked to long-term rubber land use and land use change affect topsoil physico-chemical properties and soil organic carbon (SOC) thermal stability. We focus on the effects of three factors: i. deforestation (change from forest to first rubber plantation); ii. the age of the rubber stand (immature vs. mature); and iii. long-term rubber cultivation (first, second or third successive rotation) over a chronosequence in farmers plots. Our results show that soil was deeply degraded after deforestation to a rubber plantation. Long-term rubber cultivation is also detrimental for the soil and has a more negative impact on soil physico-chemical properties and carbon dynamics, than the age of the rubber stand (e.g., on average, decrease of 50% of SOC content between forest and third rotation). At the third rotation, after 50 years of rubber cultivation, the quality of the 0-10 cm soil layer was very low, with an increase in SOC thermal stability. At this stage, logging practices upset the sustainability of the system. These impacts could be limited by less destructive practices during planting.

Abstract

This work presents a flexible epoxidized soybean oil-based epoxy foam and epoxidized mangosteen tannin (EMT). The flexible foam was synthesized without catalyst, from epoxidized soybean oil (ESO) and methyltetrahydrophthalic anhydride (MTHPA) at a weight ratio ESO:MTHPA of 75:25. EMT was used as a reinforcing material. The advantages of EMT were its rigid benzene ring, co-crosslinking with ESO and curing with MTHPA. Mangosteen tannins were extracted from mangosteen pericarps and depolymerized by thiolysis reaction prior to epoxidation with epichlorohydrin. The effect of EMT content was assessed from 0.5 to 2.0 wt% of ESO. Azodicarbonamide and zinc oxide were used as a blowing agent and an activator, respectively. The experimental results indicated synergistic behavior, as EMT reinforced the epoxy foams by increasing compressive strength and decreasing compression set, whereas foam density increased with EMT content. Fourier transform infrared spectrophotometer analysis, swelling and soluble fraction testing indicated complete crosslinking of the epoxy foam. The addition of EMT also increased glass transition temperature (Tg) and degradation temperature of the epoxy foam. All epoxy foam samples showed subzero Tg (-6.5 to -5.4 °C) and semi-closed cells with irregular shapes. The derived epoxy foam was classified as a flexible foam due to its low Tg and mixture of open and closed cells.

Abstract

International audience; Tyramine production of 20 strains of lactic acid bacteria and coagulase-negative staphylococci isolated from Thai traditional fermented shrimp (kung-som) was investigated by using chromatographic and molecular methods. Among 20 strains tested, Enterococcus faecalis 9Y, Enterococcus faecalis DOKS13 and Weissella cibaria DOKS11 were able to produce tyramine and also harbor the tyrosine decarboxylase (tdc) gene. This indicated a positive correlation existing between the presence of tdc gene and production of tyramine. The effectiveness of nisin Z-producing Lactococcus lactis KTH0-1S against tyraminogenic strains was evaluated in co-cultivation experiments. Both co-culture of E. faecalis DOKS13 and W. cibaria DOKS11 with L. lactis KTH0-1S significantly decreased the growth rate and the maximal cell concentration, depending on the initial inoculum level of tyraminogenic strain. The reduction of tyramine accumulation decreased strongly when tyraminogenic strain was inoculated at 4.0 log cfu/mL and, to a lesser extent, at 5.0 and 6.0 log cfu/mL. Additionally, the inoculated kung-som with L. lactis KTH0-1S as starter culture showed significantly lower (p < 0.05) of Enterobacteriaceae, Staphylococcus aureus and total viable bacteria count than those of spontaneous kung-som. The addition of L lactis KTH0-1S as a starter culture in kung-som was markedly reducing accumulation of tyramine by about 100 mg/kg in comparison with naturally fermented kung-som. Hence, the use of bacteriocinogenic amine-negative strain as a starter culture is advisable for production of safer kung-som with minimalized pathogen contaminants and lowering the tyramine content.

Abstract

Aim: To characterize microbial communities present in natural rubber (NR) coagula from Hevea brasiliensis latex during maturation and identify microbial taxa (bacteria and fungi) having an impact on dry NR properties. Methods and Results: Microbial community dynamics in NR coagula maturated under controlled conditions were compared and related with the evolution of dry NR properties. The pyrosequencing of 16S (119 837 effective reads) and 18S (131 879 effective reads) rRNA gene regions was performed on 21 samples covering different maturation times and two aeration conditions. Results showed a relatively high bacterial richness (Chao1 estimates of 200–1000) associated with significant bacterial dynamics. Lactic acid bacteria (LAB) were dominant in the first days of maturation. Then, in aerobic conditions, development of Actinobacteria represented by the family Microbacteriaceae was associated with alkalinization of the samples and a higher sensitivity of NR to thermo-oxidation as evaluated by its plasticity retention index (PRI). In anaerobiosis, the reduced development of bacteria, mostly LAB present, was associated with improved NR properties (higher initial plasticity P0 and PRI). Conclusions: The involvement of micro-organisms in the evolution of dry NR properties during the maturation of NR coagula was confirmed. The importance of the structure and dynamics of microbial communities is specifically highlighted. Significance and Impact of the Study: Natural rubber is a key elastomer for the tyre industry and for a variety of other applications. The majority of raw NR is obtained by natural coagulation of H. brasiliensis latex under the activity of micro-organisms. An improved understanding of the microbial communities involved in the maturation of NR coagula may lead to an improvement in the production process of raw NR to provide a better consistency in NR quality.

Abstract

International audience; Chikungunya virus (CHIKV) is an emerging arbovirus of the Togaviridae family that poses a present worldwide threat to human in the absence of any licensed vaccine or antiviral treatment to control viral infection. Here, we show that compounds interfering with intracellular cholesterol transport have the capacity to inhibit CHIKV replication in human skin fibroblasts, a major viral entry site in the human host. Pretreatment of these cells with the class II cationic amphiphilic compound U18666A, or treatment with the FDA-approved antidepressant drug imipramine resulted in a near total inhibition of viral replication and production at the highest concentration used without any cytotoxic effects. Imipramine was found to affect both the fusion and replication steps of the viral life cycle. The key contribution of cholesterol availability to the CHIKV life cycle was validated further by the use of fibroblasts from Niemann-Pick type C (NPC) patients in which the virus was unable to replicate. Interestingly, imipramine also strongly inhibited the replication of several $Flaviviridae$ family members, including Zika, West Nile and Dengue virus. Together, these data show that this compound is a potential drug candidate for anti-arboviral treatment.

Abstract

© 2017 Trans Tech Publications, Switzerland. Calcium phosphate materials can be produced using a number of wet methods that are based on hydrothermal or co-precipitation methods that might use acidic or basic chemical environments. In our previously published works, we have investigated calcium phosphates such as monetite, hydroxyapatite, and whitlockite which were successfully produced by mechano-chemical methods and/or hydrothermal treatments from a range of marine shells and corals which were obtained from the Great Barrier Reef. The aim of the current work was to analyze and compare the mechanisms of conversion of one hard coral species and one calcified algae species from the Great Barrier Reef.

Abstract

Streptomyces is a genus known for its ability to protect plants against many pathogens and various strains of this bacteria have been used as biological control agents. In this study, the efficacy of Streptomyces philanthi RM-1-138, S. philanthi RL-1-178, and Streptomyce mycarofaciens SS-2-243 to control various strains of Botrytis cinerea was evaluated both in vitro and in vivo. In vitro studies using confrontation tests on PDA plates indicated that the three strains of Streptomyces spp. inhibited the growth of 41 strains of B. cinerea. Volatile compounds produced by Streptomyces spp. had an influence on the growth of ten strains of B. cinerea while its culture filtrate at low concentration (diluted at 10−3) showed a complete inhibition (100%) of spore germination of B. cinerea strain BC1. A significant protection efficacy of tomato against B. cinerea was observed on both whole plant test (57.4%) and detached leaf test (60.1%) with S. philanti RM-1-138. Moreover, this antagonistic strain had a preventive and a curative effect. These results indicated that S. philanthi RM-1-138 may have the potential to control gray mold caused by B. cinerea on tomato but further work is required to enhance its efficacy and its survival in planta.

Abstract

Lactococcus lactis KTH0-1S isolated from Thai traditional fermented shrimp (Kung-som) is able to produce heat-stable bacteriocin and inhibits food spoilage bacteria and food-borne pathogens. The inhibitory effect of bacteriocin remained intact after treatment with different pHs and after heating, but was sensitive to some proteolytic enzymes. Addition of bacteriocin KTH0-1S to Staphylococcus aureus cultures decreased viable cell counts by 2.8 log CFU/ml, demonstrating a bactericidal mode of action. Furthermore, the growth of S. aureus decreased significantly after 12-h co-cultivation with bacteriocinogenic strain. The molecular mass of bacteriocin KTH0-1S was found to be 3.346 kDa after ammonium sulfate precipitation, reversed phase (C-8 Sep-Pak), cation-exchange chromatography, RP-HPLC on C-8 column and mass spectrometry (MS/MS) analysis. Bacteriocin KTH0-1S was identified as nisin Z using PCR amplification and sequencing. The majority of tested virulence factors were absent, confirming the safety. Evidenced inhibitory effect of this strain, the absence of virulence factors creates the possibility for its application as protective culture to inhibit pathogenic bacteria in the several fermented seafood products.

Abstract

The effect of the type of epoxidation processes of soybean oil on the characteristics of epoxidized soybean oils (ESOs), acrylated epoxidized soybean oils (AESOs), and acrylated epoxidized soybean oil - poly(methyl metacrylate) copolymers (AESO-co-PMMA) has been investigated. Two epoxidation processes were used: an in situ chemical epoxida- tion using hydrogen peroxide and formic acid, and a chemo-enzymatic epoxidation using 2 enzymes: Novozyme ® 435 (CALB) and a homemade lipase/acyltransferase (CpLIP2). ESOs containing different numbers of epoxide groups/molecule were synthesized. A commercial ESO (Vikoflex ® 7170) was employed and it had the highest number of epoxide groups. Acrylation of ESOs was carried out using acrylic acid, and copolymerized with a methyl methacrylate monomer. The chemo-enzymatic epoxidation produced high acid value, particularly from the CpLIP2 (! 46-48%) and indicated the for- mation of epoxidized free fatty acids. In contrast, the ESO synthesized from the chemical epoxidation showed a very low acid value, < 0.6%. The AESOs synthesized from the CALB-based ESO and the chemical-based ESO showed a similar number of acrylate groups/molecule while that from the CpLIP2-based ESO showed a very low number of acrylate groups because the carboxylic groups from the epoxidized free fatty acids impeded the acrylation reaction. The lower the number of acrylate groups the lower was the crosslink density, the Tg, and the gel content in the AESO-co-PMMA copolymer.

Abstract

The potential impact of global temperature change on global crop yield has recently been assessed with different methods. Here we show that grid-based and point-based simulations and statistical regressions (from historic records), without deliberate adaptation or CO2 fertilization effects, produce similar estimates of temperature impact on wheat yields at global and national scales. With a 1 °C global temperature increase, global wheat yield is projected to decline between 4.1% and 6.4%. Projected relative temperature impacts from different methods were similar for major wheat-producing countries China, India, USA and France, but less so for Russia. Point-based and grid-based simulations, and to some extent the statistical regressions, were consistent in projecting that warmer regions are likely to suffer more yield loss with increasing temperature than cooler regions. By forming a multi-method ensemble, it was possible to quantify ‘method uncertainty’ in addition to model uncertainty. This significantly improves confidence in estimates of climate impacts on global food security.

Abstract

National audience; This research paper proposes IEEE802.3az incorporated green algorithmic schemes on the software defined networking-based segment routing (SDN-based SR) centralized network. The proposed schemes are the green (i.e. the EAGER and CARE metrics) SDN-based SR networks with and without traffic engineering (TE) tunneling. Green metrics extend the IEEE 802.3az energy saving to the whole network, while tunneling avoids the load sharing mechanism included in the segment routing that is not convenient for energy saving purpose. The findings of emulation revealed that the energy efficiency under the EAGER-tunneling strategy is comparable to the conventional metric with TE tunneling, and the saving realized under the CARE-tunneling scheme is twofold in comparison with the LEGACY-tunneling strategy. Meanwhile, the energy saving performance achieved with all three metrics under TE non-tunneling was inferior to those with tunneling. Nonetheless, the lower end-to-end delay and lower maximum link utilization (MLU) were achievable with the non-tunneling strategy.

Abstract

Bio-based polyurethane foam (PUF) was synthesized by a one-shot polymerization using hydroxyl telechelic natural rubber (HTNR) and polycaprolactone (PCL) diols as a soft segment. The effect of HTNR/PCL diol molar ratio (1/0, 1/0.5, 1/1 and 0.5/1) on the foam formation rate and physical and mechanical properties of the resulting PUF was investigated. The formation of urethane linkage and cross-linked structure were confirmed by FTIR analysis. The foams observed by scanning electron microscope revealed to have almost closed cells. The molar ratio of HTNR/PCL diol affected the foam formation rate, the average diameter of cell, the regularity of cell shape, the elongation at break and the compressive strength. The foam density slightly changed with this molar ratio whereas the specific tensile strength of all samples was in the same range. All PUFs showed relatively high compression set. The biodegradability was assessed according to a modified Sturm test. Low density polyethylene and sodium benzoate were used as a negative and positive control sample, respectively. PUF samples showed an induction time of 33 days in which the percentage of biodegradation was ~7–11 %. At the end of testing (60 days), the highest degradation (45.6 %) was found in the sample containing 1/0.5 of HTNR/PCL diol molar ratio.

Abstract

International audience; The software integration with new network architectures via Software Defined Network (SDN) axis appears to be a major evolution of networks. While this paradigm was primarily developed for easy network setup, its ability to integrate services has also to be considered. Thus, the mobility service for which solutions have been proposed in conventional architectures by defining standardized protocols should be rethought in terms of SDN service. Mobile devices might use or move in SDN network. In this paper, we have shown that SDN can be implemented without IP mobility protocol for providing mobility like as Proxy Mobile IPv6 (PMIPv6) that is the solution adopted by 3GPP, with some performance gain.

Abstract

Poster présenté à 13. IOBC-WPRS Meeting of the working group "Biological control of fungal and bacterial plant pathogens". Biocontrol of plant diseases: "from the field to the laboratory and back again", Uppsala, SWE (2014-06-15 - 2014-06-18).; International audience; Grey mould caused by the fungus Botrytis cinerea is an economically important disease in numerous crops. Biocontrol is a promising method to control the disease. Species of Streptomyces are potential biological control agents since they are ubiquitous in the environment and many of them produce various secondary metabolites with diverse biological activities including the ability to inhibit this plant pathogenic fungus. Strains RM-1-138 and RL-1-178 of S. philanthi and SS-2-243 of S. mycarofaciens, isolated from the rhizosphere soil of chili peppers grown in southern Thailand, have shown a good efficacy to control Sclerotium roljsii, Ralstonia solanacearum and Rhizoctonia solani but their effect against B. cinerea is not known. In this study we evaluated the efficacy of the three strains of Streptomyces spp. against B. cinerea in vitro and on tomato plants. Results indicated that the three strains inhibit the growth of B. cinerea in Petri plates and have a significant protective efficacy, although variable between strains of Streptomyces spp., against B. cinerea on tomato plant. To assess the possible variability in susceptibility to these antagonistic strains in populations of B. cinerea, the protective efficacy of these bacteria were evaluated against 41 strains differing in their geographic origin, host of isolation and level of aggressiveness. Results based on confrontation tests in Petri plates suggest a diversity in the sensitivity of the different strains of B. cinerea to these biological control agents. The relevance of these results to ensure durability of the efficacy of these biological control agents will be discussed.

Abstract

International audience; The probability density function (pdf) of an electromyography (EMG) signal provides useful information for choosing an appropriate feature extraction technique. The pdf is influenced by many factors, including the level of contraction force, muscle type, and noise. In this paper, we investigated the pdfs of noisy EMG signals artificially contaminated with five different noise types: 1) Electrocardiography (ECG) interference; 2) many spurious background spikes; 3) white Gaussian noise; 4) motion artifact; and 5) power line interference at various levels of signal-to-noise ratio (SNR). In addition, we evaluated a set of statistical descriptors for identifying a noisy EMG signal from its pdf, specifically kurtosis, negentropy, L-kurtosis, and robust measures of kurtosis (KR 1 and KR 2 ). The results show that at low SNR (

Abstract

International audience; Lactococcus lactis subsp. lactis KT2W2L was used for biopreservation in cooked, peeled and ionized tropical shrimps (CPITS) during storage at 8 A degrees C under modified atmosphere packaging (MAP). The neutralized and filtered cell-free supernatant produced by this strain exhibited a broad spectrum of inhibition against 23 strains from 24 indicator strains of food-spoilage bacteria and food-borne pathogens by agar well diffusion assay. The growth of Brochothrix thermosphacta CD274, Carnobacterium maltaromaticum CD263 and Listeria innocua CIP 80.11T was inhibited by L. lactis subsp. lactis KT2W2L when co-cultivated at 25 A degrees C. However, only L. innocua CIP 80.11T was inhibited in a co-cultivation at 8 A degrees C. L. lactis subsp. lactis KT2W2L was then used for biopreservation in CPITS. Growth of bacteria group inoculated in CPITS was monitored at regular intervals during storage period under MAP at 8 A degrees C by microbial counts and the thermal temperature gradient gel electrophoresis (TTGE) technique. L. lactis subsp. lactis KT2W2L inhibited the growth of B. thermosphacta and L. innocua CIP 80.11T batches after 7 days of storage. However, it was inactive against C. maltaromaticum batch. The growth of L. lactis subsp. lactis KT2W2L alone or in the presence of indicators increased to reach about 8-9 log CFU/g within 7 days of storage and remained constant until the end of the experiment. In the batches without L. lactis subsp. lactis KT2W2L, all bacterial groups grew well on the cooked shrimp matrix, reaching their maximal levels after 2 weeks of storage. The pH of all homogenized suspensions of MAP-CPITS was quite stable at 6.0-6.7. The control batches were under the enumeration threshold (< 1.70 +/- A 0.00 log CFU/g) until 14 days of storage, and then, an increase in growth was detected on agar plates. In addition, TTGE revealed to be an excellent tool to monitor the change of the microbial ecosystem in this product.

Abstract

Production of Thai fish paste Ka-pi-plaa fermented using beardless barb, Cyclocheilichthys apogon was monitored. Physicochemical, microbiological and antioxidant properties were compared after each process, i.e., autolysis, salting, sun-drying and fermentation. Color parameters L* decreased while a* and b* increased during production (PKa-pi-plaa finished product presented an intense brown color as shown with the increase in browning intensity (A420). Contents of formal nitrogen, ammonia nitrogen and amino nitrogen showed continuous increase (PKa-pi-plaa possessed 2,2-diphenyl-l-picrylhydrazyl and 2,2-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) scavenging and metal chelating activities, and ferric reducing power. This study provides important information on the relationship among production steps, various properties and chemical reactions for fish fermentation.

Abstract

Thailand is today the richest country for the genus Troglopedetes Joseph, 1872, with 17 species described from the country. In this study three troglomorphic new species are described from caves in the western region. They are T. spectabilissp. nov. and T. rungsimaesp. nov. from Kanchanaburi province and T. takensissp. nov., from Tak province. The three new species share elongated antennae and have the same number of central mac on Th. III and Abd. IV. However, they differ from one another by the combination of: presence of eyes, antennal length, claw morphology, central head macrochaetotaxy and internal row of dental spines. Troglopedetes spectabilissp. nov. is remarkably different from its congeners by its extreme long appendages, especially the antennae (ratio antenna: head = 5.5). In the second part of the paper the arrangment of antennal chaetotaxy and the diversity of its phaneres is analyzed in the three new species, homologized and compared with those of two other species described from Thailand (T. meridionalis and T. kae). A total of 22 types of chaetae have now been recognized among the species. A new type of S-chaetae for the genus was discovered in this study. There are 5 types of ordinary chaetae, 15 types of S-chaetae, the subapical organite of Ant. IV and scales. A total of 1,107 to 2,183 antennal chaetae on each side were observed, which includes 308–485 S-chaetae, 687–1,402 ordinary chaetae, 72–295 scales and a subapical organite.
