Quantification of Recharge and Runoff from Rainfall Using New GIS Tool: Example of the Gaza Strip Aquifer
Authors: Mushtaha Ashraf M. , Van Camp Marc , Walraevens Kristine
Published: January 2019

The Gaza Strip forms a transition zone between the semi-humid coastal zone in the north, the semi-arid zone in the east, and the Sinai desert in the south. Groundwater is the only water source for 1.94 million inhabitants, where the only fresh replenishment water for the aquifer comes from rainfall. This study focuses on testing a newly developed GIS tool to estimate the spatial and temporal distribution of runoff and recharge from rainfall. The estimation of surface runoff was made using the Soil Conservation Services Curve Number Method, while groundwater recharge was estimated using Thornthwaite and Mather’s Soil Moisture Balance approach. The new tool was applied to the Gaza aquifer for the year 1935 and for the period from 1973 to 2016. A comparison was made between the results obtained with the developed GIS tool and the frequently used Thiessen polygon method for rainfall distribution. Runoff and recharge were estimated for the year 1935 (prior to development) to compare with the current developed conditions. It was found that the built-up and sand dune areas stand in an inverse relationship, where the former is replacing the latter (built-up area expanded from 30.1 km2 in 1982 to 92.1 km2 in 2010). Recharge takes place in the sand dune area, whereas runoff increases in the built-up area. Due to development, runoff almost tripled from 9 million m3 in 1982 to 22.9 million m3 in 2010, while groundwater recharge was reduced from 27.3 million m3 in 1982 to 23 million m3 in 2010, even though the rainfall increased between 1982 and 2010 by 11%. Comparison between the newly developed GIS tool and the Thiessen polygon-based estimation shows that the former leads to higher values of runoff and recharge for dry years.
Applicability of ε-Support Vector Machine and Artificial Neural Network for Flood Forecasting in Humid, Semi-Humid and Semi-Arid Basins in China
Authors: Bafitlhile Thabo Michael , Li Zhijia
Published: January 2019

The aim of this study was to develop hydrological models that can represent different geo-climatic system, namely: humid, semi-humid and semi-arid systems, in China. Humid and semi-humid areas suffer from frequent flood events, whereas semi-arid areas suffer from flash floods because of urbanization and climate change, which contribute to an increase in runoff. This study applied ɛ-Support Vector Machine (ε-SVM) and artificial neural network (ANN) for the simulation and forecasting streamflow of three different catchments. The Evolutionary Strategy (ES) optimization method was used to optimize the ANN and SVM sensitive parameters. The relative performance of the two models was compared, and the results indicate that both models performed well for humid and semi-humid systems, and SVM generally perform better than ANN in the streamflow simulation of all catchments.

Published: January 2019

Understanding the dynamics of pesticide transport in the Malewa River and Lake Naivasha, a major fresh water resource, is critical to safeguard water quality in the basin. In this study, the soil and water assessment tool (SWAT) model was used to simulate the discharge of sediment and pesticides (notably the organochlorine residues of lindane, methoxychlor and endosulfan) into the Malewa River Basin. Model sensitivity analysis, calibration and validation were performed for both daily and monthly time steps using the sequential uncertainty fitting version 2 (SUFI-2) algorithm of the SWAT-CUP tool. Water level gauge data as well as a digital turbidity sensor (DTS-12) for suspended sediment transport were used for the SWAT calibration. Pesticide residues were measured at Upper and Down Malewa locations using a passive sampling technique and their quantity was determined using laboratory gas chromatography. The sensitivity analysis results showed that curve number (CN2), universal soil loss equation erodibility factor (USLE-K) and pesticide application efficiency (AP_EF) formed the most sensitive parameters for discharge, sediment and pesticide simulations, respectively. In addition, SWAT model calibration and validation showed better results for monthly discharge simulations than for daily discharge simulations. Similarly, the results obtained for the monthly sediment calibration demonstrated more match between measured and simulated data as compared to the simulation at daily steps. Comparison between the simulated and measured pesticide concentrations at upper Malewa and down Malewa locations demonstrated that although the model mostly overestimated pesticide loadings, there was a positive association between the pesticide measurements and the simulations. Higher concentrations of pesticides were found between May and mid-July. The similarity between measured and simulated pesticides shows the potential of the SWAT model as initial evaluation modelling tool for upstream to downstream suspended sediment and pesticide transport in catchments.

Published: January 2019

Glaciers have an important hydrological buffering effect, but their current rapid reduction raises concerns about future water availability and management. This work presents a hydrological sensitivity analysis to different climatic and glacier cover conditions, carried out over four catchments with area between 8 and 1050 km2, and with glacierization between 2% and 70%, in the Italian Alps. The analysis is based on past observations, and exploits a unique dataset of glacier change and hydro-meteorological data. The working approach is aimed at avoiding uncertainties typical of future runoff projections in glacierized catchments. The results highlight a transition from glacial to nival hydrological regime, with the highest impacts in August runoff over smaller catchments. The buffering effect of current glaciers has largely decreased if compared to the Little Ice Age, up to 75% for larger catchments, but it is still important during warm and dry summers like 2003. We confirm a non-linear relationship between glacier contribution in late summer and catchment area/percent glacierization. The peak in runoff attributable to glacier melt, expected in the next 2–3 decades on highly glacierized alpine catchments, has already passed in the study area.

Published: January 2019

Crop water requirements are directly affected by climatic variability, especially for crops grown in the areas which are sensitive to climatic change. Based on the SIMETAW model and a long-term meteorological dataset, we evaluated the spatiotemporal variations of climatic change impacts on water requirement of oat in North and Northeast China. The results indicated that effective rainfall showed an increasing trend, while the crop water requirement and irrigation demand presented decreasing trends over the past decades. The water requirement of oat showed significant longitudinal and latitudinal spatial variations, with a downtrend from north to south and uptrend from east to west. Climatic factors have obviously changed in the growth season of oat, with upward trends in the average temperature and precipitation, and downward trends in the average wind speed, sunshine hours, relative humidity, and solar radiation. Declines in solar radiation and wind speed, accompanied with the increase in effective rainfall, have contributed to the reduced crop water requirement over these decades. Given the complex dynamic of climate change, when studying the impact of climate change on crop water requirements, we should not only consider single factors such as temperature or rainfall, we need to analyze the comprehensive effects of various climatic factors.

Droughts constitute natural hazards that affect water supply for ecosystems and human livelihoods. In 2013–2016, the Caribbean experienced the worst drought since the 1950s, and climate projections for the southern Caribbean predict less rainfall by the end of the 21st century. We assessed streamflow response to drought for a watershed in the Colombian Caribbean by analyzing the effects of drought length and land cover on streamflow recovery. We generated a calibrated SWAT model and created annual and monthly drought scenarios from rainfall records. We used our model to predict water yield for selected land covers (wet forest, shade coffee, shrub, and dry forest) under drought conditions. Annual scenarios resulted in water yield reductions of ~15 mm month−1 (wet forest, coffee, and shrub) and 5 mm month−1 (dry forest) for the first month after a two-year drought. Maximum water yield reductions for monthly scenarios occurred after a 10-month drought and were ~100 mm month−1 (wet forest, coffee, and shrub) and 20 mm month−1 (dry forest). Streamflow recovered within nine months (annual scenarios), and two to eight months (monthly scenarios) after drought termination. Drought response seems to be conditioned by climatic factors (rainfall seasonality and spatial variability) and catchment properties.

Published: January 2019

In this work, we investigated the parameters for decorating multiwalled carbon nanotubes with iron oxide nanoparticles using a new, inexpensive approach based on wet chemistry. The effect of process parameters such as the solvent used, the amount of iron salt or the calcination time on the morphology, decoration density and nanocluster size were studied. With the proposed approach, the decoration density can be adjusted by selecting the appropriate ratio of carbon nanotubes/iron salt, while nanoparticle size can be modulated by controlling the calcination period. Pristine and iron-decorated carbon nanotubes were deposited on silicon substrates to investigate their gas sensing properties. It was found that loading with iron oxide nanoparticles substantially ameliorated the response towards nitrogen dioxide.
OPTIMAL AIRLINE SEAT INVENTORY CONTROL FOR MULTI‐LEG FLIGHTS
Authors: Vasermanis Edgars K. , Nechval Nicholas A. , Nechval Konstantin N. , Rozite Kristine N.
Published: January 2019

Airline seat inventory control is about “selling the right seats to the right people at the right time”. In this paper, the problem of determining optimal booking policy for multiple fare classes in a pool of identical seats for multi‐leg flights is considered. During the time prior to departure of a multi‐leg flight, decisions must be made concerning the allocation of reserved seats to passengers requesting space on the full or partial spans of the flight. It will be noted that in the case of multi‐leg flights the long‐haul passengers are often unable to obtain seats because the shorter‐haul passengers block them. For large commercial airlines, efficiently setting and updating seat allocation targets for each passenger category on each multi‐leg flight is an extremely difficult problem. This paper presents static and dynamic models of airline seat inventory control for multi‐leg flights with multiple fare classes, which allow one to maximize the expected contribution to profit. The dynamic model uses the most recent demand and capacity information and allows one to allocate seats dynamically and anticipatorily over time.
Direct Measurement of Quasar Outflow Wind Acceleration*

Published: January 2019

We search for velocity changes (i.e., acceleration/deceleration) of narrow absorption lines (NALs) that are intrinsic to the quasars using spectra of six bright quasars that have been observed more than once with 8–10 m class telescopes. While variations in line strength and profile are frequently reported (especially in broader absorption lines), definitive evidence for velocity shifts has not been found, with only a few exceptions. Direct velocity shift measurements are valuable constraints on the acceleration mechanisms. In this study, we determine velocity shifts by comparing the absorption profiles of NALs at two epochs separated by more than 10 yr in the observed frame using the cross-correlation function method, and we estimate the uncertainties using Monte Carlo simulations. We do not detect any significant shifts, but we obtain 3σ upper limits on the acceleration of intrinsic NALs (compared to intervening NALs in the same quasars) of ∼0.7 km s−1 yr−1 (∼0.002 cm s−2) on average. We discuss possible scenarios for nondetection of NAL acceleration/deceleration and examine the resulting constraints on the physical conditions in accretion disk winds.

Published: January 2019

Arp 187 is one of the fading active galactic nuclei (AGNs), whose AGN activity is currently decreasing in luminosity. We investigate the observational signatures of AGN in Arp 187, which trace various physical scales from less than 0.1 pc to the nearly 10 kpc, to estimate the long-term luminosity change over 104 yr. The Very Large Array 5 GHz and 8 GHz images and the ALMA 133 GHz images reveal bimodal jet lobes with ∼5 kpc size and the absence of the central radio core. The 6dF optical spectrum shows that Arp 187 hosts a narrow line region with the estimated size of ∼1 kpc, and the line strengths give the AGN luminosity of L
bol = 1.5 × 1046 erg s−1. On the other hand, the current AGN activity estimated from the AGN torus emission gives the upper bound of L
bol < 2.2 × 1043 erg s−1. The absence of the radio core gives the more strict upper bound of the current AGN luminosity of L
bol < 8.0 × 1040 erg s−1, suggesting that the central engine is already quenched. These multiwavelength signatures indicate that Arp 187 hosts a “dying” AGN: the central engine is already dead, but the large-scale AGN indicators are still observable as the remnant of the past AGN activity. The central engine has experienced the drastic luminosity decline by a factor of ∼103–5 fainter within ∼104 yr, which is roughly consistent with the viscous timescale of the inner part of the accretion disk within ∼500 yr.

La politique pénale et carcérale au Brésil, terreau du crime organisé et de la violence meurtrière
Authors: Souchaud Sylvain
Published: January 2019

L’article examine les liens entre l’assassinat spectaculaire en juin 2016 de Jorge Rafaat Toumani, riche entrepreneur paraguayen et « roi du trafic » installé à Pedro Juan Caballero, ville de l’est du Paraguay située à la frontière brésilienne ; les massacres dans les prisons amazoniennes et du Nordeste qui ont fait plusieurs centaines de morts en 2017 ; et la guerre des gangs qui sévit actuellement à Rocinha, la plus célèbre favela de Rio de Janeiro. Ces événements survenus dans des régions distantes au Brésil et qui secouent le pays depuis deux ans ont en commun la stratégie de reconfiguration et de redéploiement territorial des activités du Primeiro Comando da Capital (PCC), groupe mafieux centré dans l’État de São Paulo, initiée il y a plusieurs années. Le nouveau tournant pris par le PCC, dont la stratégie récente vise à étendre son emprise territoriale sur le trafic de drogues (circulation et commercialisation) au Brésil, marché consommateur et plaque tournante régionale, se heurte à l’opposition du Comando Vermelho (CV), autre groupe dominant du crime organisé basé quant à lui à Rio de Janeiro. L’opposition désormais frontale et violente entre les deux factions se répercute dans l’ensemble du Brésil, n’épargnant aucune région. En complément de l’analyse des stratégies territoriales des différentes factions, l’examen des faits montre comment la puissance du PCC s’enracine dans les orientations et les failles des politiques pénale et carcérale de l’État brésilien, pays où ces dernières décennies les conditions de vie en prison se dégradent dramatiquement à mesure que le taux d’incarcération augmente. C’est en effet à partir du contrôle des prisons de l’État de São Paulo que le PCC a étendu son influence et développé ses activités, en installant une politique systématique d’enrôlement des détenus et de corruption des administrations carcérales.
La neuro-amélioration des sujets « sains » : enjeux anthropologiques, sociologiques et juridiques
Authors: Larrieu Peggy
Published: January 2019

Avec les avancées des neurosciences, le marché de l’amélioration cérébrale est en plein essor. Il est vrai que sous réserve des risques éventuels pour la santé publique, la neuro-amélioration semble relever de la seule liberté individuelle et du droit à la libre disposition de soi. Cependant, cette évolution, bénéficiant de la profonde ambiguïté qui existe entre les notions de santé, de bien-être et de performance, amène à s’interroger. Car ce phénomène de médicalisation de la société pourrait remettre en cause toutes nos conceptions de la personne humaine et introduire un déséquilibre dans les rapports sociaux.

Entre typhons et menace chinoise, Taiwan zone critique de la géo-politique
Authors: Jobin Paul
Published: January 2019

Empruntant la notion de zone critique aux géologues, Bruno Latour invite à dépasser la géopolitique du régime westphalien, un cadre jugé obsolète pour affronter la crise de l’anthropocène. A travers deux terrains d’observation et des enquêtes quantitatives, je considère ici Taiwan comme une zone particulièrement critique de la crise écologique mondiale. Cependant, dans le contexte taiwanais, compte tenu de la menace chinoise, le risque géopolitique de type classique ne peut être traité à la légère. Jusqu’à présent, les désastres dus au réchauffement climatique tels que typhons et glissements de terrain sont envisagés séparément des risques géostratégiques comme le blocus économique ou une invasion armée. Dans une première partie, nous suivons en compagnie de Bruno Latour lui-même une équipe internationale de géologues dans les gorges de Taroko tandis qu’une mine de la firme Asia Cement menace un village aborigène. Nous nous rendons ensuite sur l’atoll de Dongsha en Mer de Chine, où les militaires taiwanais aident des chercheurs spécialistes de biologie marine à ramasser les déchets en matière plastique venus de toute l’Asie, tandis que les bateaux chinois rôdent. Enfin, une dernière partie présente des enquêtes d’opinion qui traitent d’une part du risque écologique et d’autre part de la menace d’une invasion armée chinoise. En conclusion, je propose une géopolitique qui tienne compte et de la crise écologique et de la menace géostratégique.
Kim et Trump : nouveaux calculs stratégiques

Partie de poker ou jeu de dupes, les mots manquent pour qualifier l’enchaînement rapide de contacts qui a mené au sommet Kim-Trump de Singapour en juin 2018 et à la reprise d’une négociation active menée pour l’essentiel par le secrétaire d’État américain à Pyongyang. Les paris stratégiques de chacun des protagonistes – avec en toile de fond le souci probable de Kim Jong-un d’échapper à une mainmise chinoise complète, et celui de Donald Trump de limiter l’engagement futur des États-Unis dans un conflit sur la péninsule coréenne – constituent les principales, et peut-être les seules raisons d’espérer une véritable avancée.
Les migrations de la Corée contemporaine : état(s) et diaspora(s)
Authors: Eunsil Yim
Published: January 2019

Le phénomène diasporique de la Corée se caractérise aujourd’hui par une dynamique de flux migratoire, comme en témoignent l’augmentation constante du nombre de Coréens à l’étranger et, à titre corollaire, l’investissement croissant des États nord- et sud-coréens dans la politique de gestion de ces Coréens d’outre-mer. Pour rendre compte de la singularité du cas de la Corée dans un monde de plus en plus globalisé, le présent article souhaite poser les questions fondamentales qui déterminent la problématique de la diaspora coréenne, à savoir la situation géopolitique de la péninsule coréenne, la logique de confrontation Nord / Sud qui en découle et les manières dont cette logique se transpose sur les conditions diasporiques.
Représentations sociales de l’alcool au sein de la Marine nationale
Authors: Casanova Clémence , Berger Franck , Meynard Jean-Baptiste , Apostolidis Thémistoklis , Michel Rémy
Published: January 2019

Introduction : Le mésusage de l’alcool a des répercussions nocives sur la sphère sociale et sanitaire d’une population. Les militaires français doivent être particulièrement vigilants face à l’alcool, en raison des spécificités de leur métier lié notamment au maniement des armes. Cette étude vise à explorer les représentations sociales de l’alcool au sein de la Marine nationale, afin de définir des axes prioritaires de prévention de ses mésusages d’alcool dans un environnement militaire. Méthodes : Une étude exploratoire de nature principalement qualitative, par entretiens semi-directifs, a été menée dans le Sud de la France à la fin de l’année 2015. Les données ont été analysées via une analyse catégorielle manuelle et une analyse textuelle (logiciel IRaMuTeQ). Résultats : Soixante-deux militaires de la Marine nationale ont été interrogés, dont 30 marins et 32 marins-pompiers. L’analyse des résultats indique que la motivation à consommer de l’alcool provient davantage de l’influence sociale (motivations extrinsèques) que du plaisir provoqué par les effets de l’alcool. Pour les marins, si le sentiment d’appartenance à la Marine est renforcé par des habitudes de consommation à caractère fortement cohésif, la consommation d’alcool en revanche est perçue plutôt négativement par les marins-pompiers, pouvant être causée par une dévalorisation de leur image professionnelle vis-à-vis de la population civile. Conclusion : L’identification des représentations sociales de l’alcool permet de mieux appréhender les comportements d’alcoolisation à risque d’une population de militaires français, notamment en se focalisant sur le contenu et l’organisation des discours concernant l’alcool. Suite à cette étude, une enquête quantitative est en cours d’élaboration auprès de militaires de la Marine nationale afin de clarifier certaines pistes exploratoires identifiées dans ce travail.

Genre, inégalités et promotion de la santé à l’échelle locale. L’exemple gennevillois
Authors: Faure Emmanuelle , Rican Stéphane
Published: January 2019

En France, les inégalités sociales de santé restent importantes, tant en ce qui concerne les variations d’états de santé que celles de l’accès aux soins de la population. Si leurs dimensions socio-économiques sont largement documentées, les processus concourant aux inégalités entre hommes et femmes ainsi que leur inscription dans les dynamiques territoriales restent peu analysés. Cet article vise à interroger le rôle de ces dynamiques dans l’accès des hommes et des femmes à la prévention. Nous nous appuyons sur l’étude des modalités locales de promotion de la santé dans la commune de Gennevilliers (Hauts-de-Seine) pour interroger ce processus de construction des inégalités. Des entretiens semi-directifs ont été menés auprès d’élus, de professionnels du champ sanitaire et social et d’acteurs associatifs. La consultation de différentes sources manuscrites et des observations de terrain complètent ce travail. La commune de Gennevilliers, par l’ancienneté de la prise en compte de la santé, le dynamisme des réseaux d’acteurs ou bien le nombre d’actions innovantes qui caractérisent sa politique sanitaire, constitue un exemple mobilisateur et pertinent pour l’analyse des freins et leviers de l’intervention en santé. Cet article démontre que les dispositifs de promotion de la santé s’inscrivent dans des dynamiques territoriales complexes, mais peuvent également contribuer au renforcement des normes de genre et des écarts entre hommes et femmes. Finalement, cette recherche illustre la nécessaire prise en compte des questions de genre et de territoire dans l’analyse comme dans l’élaboration des actions de promotion de la santé.

Authors: Huston Carol , Shovein Julia , Damazo Becky , Fox Sherry
Published: January 2019

ABSTRACT

Background: Although most RN-to-BSN programs offer bridge courses, little can be found in the literature about common course objectives, content, or outcomes.

Method: This article details course objectives, course content, course implementation, and preliminary outcomes of a primarily distance learning RN-to-BSN bridge course at a northern California university.

Results: Preliminary outcome assessments suggested greater than expected increases in role and campus socialization, as well as computer literacy, as a result of RN-to-BSN bridge course implementation.

Conclusion: The RN-to-BSN bridge course can successfully be used to transition the re-entry student and may be the link allowing RN-to-BSN students to effectively face the concurrent challenges of role socialization and computer literacy while mastering course content and course objectives.

Published: January 2019

This research aim developing shallot chemical mixer through mutually incorporated technology transfer technique. In comparison between innovation and manual labor, it is found that the diffusion of the machine is minimal or barely increases speed and results in safety when mixing. In term of manual labor, the diffusion process causes delay when mixing and most importantly it may lead to health concerns. As for the value of bruising of the shallot, both techniques show slow bruising value and for electricity value, the motor has a 220 V 50 Hz alternate current electricity pressure. Shallots which weigh 25 kilograms consume 0.4 current A, it could be noticed that in 1 day, 5 hours of chemical mixing- in this case shallot, it requires energy in the amount of0.44 KWh. Taking the calculated value of the rate of power used multiply by the unit of operating electricity, which each household will use less than 150 units per month, since unit 0-150 is at 1.8047 Baht, the example of electricity fee paid daily and monthly will be shown. As for the use of shallot mixture at 25 kilograms using 5 hours, the result is 1,500 kilogram of electricity at 3.97 Baht and 45,000 kilogram per month, which calculates to 23.82 Baht of electricity fee. Comparing this to manual labor of 1 day mixing, the result is 2,000 kilogram at 200 Baht expense; the chemical mixer is therefore cheaper and able to give more accurate portion of the input.It is found that the training plan and manual guiding how to use the iron threshing machine, the learners has progressed in their knowledge at the level of 72.05% and satisfaction producers in terms of its characteristic is very high and the overall overview of the operating of the prototype is very high (x=4.33).

Authors: Chomputawat Anuthep , Chatwiriya Watchara
Published: January 2019

This article compares the efficiency of vehicle trajectory analysis methods based on data fusion from multiple cameras, monitoring the same area from different views under the condition having detection errors, which causes incorrectly localized and, in some cases, undetected vehicle during the movement. The experiment used the simulation of detection and localization of vehicle moving in straight, curved, zigzag and arbitrary trajectories, with localization errors and multi-level loss of data. By comparing Kalman-filter-based method and Linear-interpolation-based method for analyzing and reconstructing vehicle trajectory, the result shows that the data loss robustness of Kalman-filter-based method is higher than that of Linear-interpolation-based method, with data loss around 97% 97% and 90% for straight, curved and zigzag trajectories respectively. However, for arbitrary trajectory, the Linear-interpolation-based method is better than Kalman-filter-based method in all levels of data loss. In conclusion, Kalman-filter-based method is effective in the case of unchanged or slight transition of direction, while Linear-interpolation-based method is effective in the case of sudden transition of direction.

From the study, it found that the internal energy, the entropy and the specific heat capacity of particle vibration bound-state under harmonics oscillator cosine asymmetric potential were increased as the increasing of the parameters of μ, η, and β. While an increasing of parameter α affected to the decreasing of the entropy and the heat capacity. In addition, the increasing values of the entropy and the specific heat capacity value were depended on the decreasing of the parameter α value.

The bound-state problem then is to solve the partition function for single-particle in the presence of anharmonics oscillator asymmetric potential.

Jasminum sambac (J. sambac) has been used as a medicinal herb with wound healing property. This experimental research proposed to evaluate the effect of J. sambac flower extracts on fibroblast cell viability and film characteristics which maybe benefit in development of wound dressing film. The testing extract of J. sambac flowers were prepared as filtration extract (F), compression of the residue flower extract (C), combination of filtration and compression extract (FC) and ethanolic extract (E). The testing extracts were evaluated the effect on fibroblast cell viability using resazurin reduction assay. NIH 3T3 fibroblast cells were treated with variable concentration of J. sambac extracts for 24, 48 and 72 h. prior to evaluate cell viability. The results demonstrated that the F and FC extract of J. sambac flower at concentration of 31.25-500 µg/ml did not induce cytotoxicity on NIH 3T3 fibroblast cells given non-cytotoxic effect. The cell viability seemed to increase at 48 h of treatment with concentration of 31.25-250 µg/ml. Meanwhile, C and E extract induced cytotoxicity on NIH 3T3 cells by reduction of cell viability. The F and FC non-cytotoxic extracts were selected to examine ability of film formation without film-based compounds and assessed physical and mechanical characteristics of the prepared films. The experimental results revealed F and FC extracts could form film after incubation at 60°C. The better physical and mechanical characteristics of the films was presented in FC film which the prepared film revealed smooth surface and better absorption and elongation. Furthermore, gelatin was blended to FC extract for assess improvement of film properties. The results revealed that gelatin-blended FC extract film gave better mechanical characteristics of the film. Non-cytotoxicity of the FC extract of J. sambac flowers on fibroblast cells and appropriate physical and mechanical characteristics of FC film may point to the usefulness of J. sambac flower extracts in herb-based film for wound dressing.

Published: January 2019

Turmeric (Curcuma longaL.), a member of Zingiberacaeae, is used for Thai traditional medicine, flavoring, preservative, and coloring agent. In Southern Thailand, turmeric is a famous ingredient for food recipes. Not only is the ripened rhizome used for cuisine, but also the young rhizomes. Previous studies have indicated that a variety of turmeric products from the ripened rhizome are valuable source of antioxidant compounds. However, there are ambiguous data regarding the level of antioxidant activity of the young rhizome. The aim of this study was to investigate the level of total phenolic content (TPC) and antioxidant activity of the young rhizomes by comparing to the ripened rhizome. TPC and antioxidant activity of aqueous and 80% methanolic extracts from the young turmeric grown in Southern Thailand were estimated using the Folin-Ciocalteu method and DPPH free radical scavenging activity (DPPH-RSA) assay, respectively. Results showed that the concentration of TPC determined in methanolic extract (19.80±0.25 mg GAE/ g extract) from the young rhizome was significantly higher than the corresponding aqueous extract (18.38±0.41 mg GAE/ g extract). The aqueous and methanolic extracts exhibited significant inhibition in DPPH-RSA with the half-maximal inhibitory concentration (IC50) value of 5.88±0.70 mg/mL and 3.00±0.31 mg/mL, respectively. However, in comparison with the ripened rhizome, TPC and DPPH-RSA of the young rhizome were lower. These results indicate that the young rhizome grown in Southern Thailand could be a source of antioxidant compounds, but the ripened rhizome provides better antioxidant properties than the young rhizome.

Published: January 2019

A simple, rapid, selective and sensitive square wave cathodic stripping voltammetry (SWCSV) at a hanging mercury drop electrode (HMDE) for the determination of As(III), As(V) and inorganic As(total) in seaweed was developed. The method was based on the formation of copper-arsenic intermetallic compound in the presence of HCl onto a HMDE at a constant potential of -0.40 V vs. Ag/AgCl in the deposition step, followed by the reduction of deposited compound to arsine at a potential of -0.78 V in the stripping step. In the system, only As(III) was directly measured, whereas inorganic As(total) was measured by reducing As(V) to As(III) using thiosulfate. In the deposition step, the use of 10 mg L-1 Cu(II) and 1 M HCl was recommended for the determination of 2 µg L-1 As(III) under the optimum instrumental variables obtained at 150 s for deposition time and 2000 rpm for stirring speed with the highest deposition efficiency of 16.15 and 88.49%, respectively. In the determination of As(V), two values of the highest reduction efficiency obtained using concentration of 40 mg L-1 thiosulfate, and reducing time at 300 s were 98.15% and 37.89%, respectively. In the measurement, the quantification limits of As(III) and As(V) were 0.46, and 1.62 µg L-1, respectively. The relative standard deviation (n=10) for 2 ug L-1 As(III) and As(V) were 5.20% and 2.57%, respectively. The proposed method was applied to the determination of inorganic arsenic species in seaweed Gracilaria fisheri.
A Study on the Prediction and Comparison of Processing Using the Artificial Neural Network in Nitinol Electrochemical Machining
Authors: Song Woo Jae , Lee Eun Sang
Published: January 2019

Nitinol consists of nickel and titanium. Nitinol is one of the shape memory alloys, which changes the crystal structure at a certain temperature and is restored to a memorized form. Because of these unique features, it is used in medical devices, high precision sensors, and aerospace industries. However, Nitinol is a traditional method of processing, resulting in thermal deformation and residual stress after processing. Therefore, the electrochemical machining (ECM), which does not produce residual stress and thermal deformation, has emerged as an alternative processing technique. This study used artificial neural network (ANN), which are the basis of AI, to replace conventional design of experiments (DOE). This method was shown to be more useful than conventional method of design of experiments (RSM, Taguchi) by applying artificial neural network to electrochamical machining (ECM) and comparing root mean square errors (RMSE).

Published: January 2019

This present work dealt with the effect of surface roughness on the scales growth of Fe-15Cr alloy. Surface morphologies and oxidation kinetics reveal that there was no obvious influence of surface roughness on the oxide-scale growth of Fe-15Cr alloy except for the initial oxidation stage of 1 h. However, there was an obvious influence on the oxide-scale spallation and microstructure, especially under the mutual function of temperature changes and surface roughness.

Published: January 2019

The results on protonation in solutions and melts of salts and acids, as well as structural changes associated with the formation of nanocomposition structure of materials are presented. It is shown by structural methods that proton localization is invariant to the volume in the protonated layer and is accompanied by changes between oxygen distances, enlargement of the unit cell and transition to the rhombic phase. Having the maximum crystal-chemical activity, protons create a hexagonal lattice in accordance with the features of equipotential pictures of their nonequilibrium electrostatic fields. The increase in the integral intensity of reflexes observed on neutronograms of protonated LiNbO3 (102), (111), (113) it is associated with the ordering of protons in the hexagonal oxygen sublattice of the initial phase.

Natural zeolite of Shivirtui deposit (Russia) was modified with nanofibers of aluminum oxyhydroxide AlOOH. Aluminum oxyhydroxide nanofibers were produced at the heating and oxidation of aluminum powder with water. The properties of modified zeolite were investigated by means of X-ray diffraction, transmission electronic microscopy, scanning electronic microscopy, low-temperature nitrogen adsorption, thermal analysis, and Fourier transform infrared spectroscopy. It was found that water content in the modified sample of zeolite was about 15 %. Based on the study of the physical and chemical properties, shivirtui zeolite modified with nanofibers of aluminum oxyhydroxide can be proposed for use as a flame-retardant additive to polymers.

Although the methylation status of histone H3K27 plays a critical role in CD4+ T cell differentiation and its function, the role of Utx histone H3K27 demethylase in the CD8+ T cell–dependent immune response remains unclear. We therefore generated T cell–specific Utxflox/flox Cd4-Cre Tg (Utx KO) mice to determine the role of Utx in CD8+ T cells. Wild-type (WT) and Utx KO mice were infected with Listeria monocytogenes expressing OVA to analyze the immune response of Ag-specific CD8+ T cells. There was no significant difference in the number of Ag-specific CD8+ T cells upon primary infection between WT and Utx KO mice. However, Utx deficiency resulted in more Ag-specific CD8+ T cells upon secondary infection. Adoptive transfer of Utx KO CD8+ T cells resulted in a larger number of memory cells in the primary response than in WT. We observed a decreased gene expression of effector-associated transcription factors, including Prdm1 encoding Blimp1, in Utx KO CD8+ T cells. We confirmed that the trimethylation level of histone H3K27 in the Prdm1 gene loci in the Utx KO cells was higher than in the WT cells. The treatment of CD8+ T cells with Utx-cofactor α-ketoglutarate hampered the memory formation, whereas Utx inhibitor GSK-J4 enhanced the memory formation in WT CD8+ T cells. These data suggest that Utx negatively controls the memory formation of Ag-stimulated CD8+ T cells by epigenetically regulating the gene expression. Based on these findings, we identified a critical link between Utx and the differentiation of Ag-stimulated CD8+ T cells.
