A Study on SM Business Internet Adoption-From The Perspective of CEO

Huang, Chen-Te 25 July 2001 (has links)
Abstract There are more than 140,000 Small-Medium Business in Taiwan, especially the CEO is always the decision-maker of the entire enterprise. This research is major through the model of ¡uTheory of Planned Behavior, TPB¡v to study the CEO¡¦s intention to e-business in Small-Medium Business. On the other hand, to understand CEO¡¦s intention to e-business is meant to understand the reason of e-business for Small-Medium Business. This research method is in accordance with an exploratory case study, then investigate by verifiable questionnaires. Through 3 internal variables and external variables of TPB model, such as ¡uAttitude toward the Internet-Adoption Behavior¡v,¡uSubjective Norms concerning the Internet-Adoption Behavior¡v , and ¡uPerceived Behavior Control concerning the Internet-Adoption Behavior¡v to understand CEO¡¦s intention to use Internet. Because of the connection between behavioral intention and actual behavior is very closed, it is to use behavioral intention in place of actual behavior to measure actual behavior in TPB model. According to the result of this study, the 3 external variables ¡uImproving Internal Information Sharer¡v,¡uPromoting the Relation with Customers¡v, and ¡uthe Past Successful Experiences¡vis the most important variables to influence¡uAttitude toward the Internet-Adoption Behavior¡v, and the most substantial is¡uthe Past Successful Experiences¡v. Furthermore, the 3 internal variables also connect with ¡uIntention toward the Internet-Adoption Behavior¡v, and the most influence among these variables is ¡uSubjective Norms concerning the Internet-Adoption Behavior¡v. Meanwhile, among 7 significant others, the major connection is between the staff of CEO and ¡uIntention toward the Internet-Adoption Behavior¡v, secondary is customer. Through the conclusion of this research, we expect to offer this data for Small-Medium Business to consult and help them to accomplish in e-business.

Recherche et développement dans le domaine des substances chimiques : préparation aux réponses du sytème REACH

Baugros, Jean-Baptiste 18 December 2008 (has links) (PDF)
L'environnement et la santé des populations sont devenus des préoccupations majeures aussi bien au niveau national qu'au niveau européen. REACH (Registration, Evaluation and Authorization of CHemicals) est un système adopté par l'Union Européenne qui regroupe plus de quarante directives afin d'éliminer et de remplacer les substances chimiques les plus toxiques. Dans ce contexte, la mise en place d'un tel système requiert des méthodes d'analyse robuste, fiables et reproductibles dans le but d'évaluer et de détecter à l'état d'ultra-traces les molécules prioritaires persistantes dans les eaux et les sols.<br />Après avoir ciblé plusieurs substances listées sur l'annexe XVII de REACH, nous avons complété cette sélection par des polluants prioritaires de l'environnement Rhône Alpin tels les pesticides. Ainsi, la méthode d'analyse proposée permet de détecter et de quantifier par CPG-SM et CPL-SM/SM 33 substances (10 alkylphénols, 5 fongicides triazole, 1 fongicide morpholine, <br />1 acaricide pyridazinone, 2 phtalates, bisphénol A, 2 insecticides carbamates, un résidu des pesticides dithiocarbamates, 2 pesticides organophosphorés et 8 organochlorés) dans des matrices environnementales aussi complexes que des effluents et des boues de station épuration. <br />L'extraction des analytes est menée par Extraction sur Phase Solide (SPE) pour les échantillons aqueux et par Extraction par Solvant Accélérée (ASE) qui a été entièrement optimisée par étude statistique des paramètres. Les extraits sont ensuite purifiés de la même manière par SPE. La préparation à la validation de ma méthode nous a permis de confirmer des limites de détection basses comprises entre 7,2 ppt et 1,27 ppb dans les eaux et entre 5 ppb et 1,7 ppm dans les boues/sols

Sm 144 Gursten : En småländsk runsten från tidig vikingatid

Åkerström, Hanna January 2012 (has links)
I denna uppsats undersöks Gurstenstenen, en småländsk runsten från tidig vikingatid. Syftet är att granska tidigare läsningar och tolkningar och revidera dessa där det behövs, samt att utifrån en sannolik tolkning av inskriften säga något om dess sakliga bakgrund och syfte. Eftersom studien syftar till att läsa och förstå text utgår metoden från en beskrivning av läsandet som psykologisk process. I varje del av detta arbete har den mest sannolika lösningen valts utifrån en jämförelse med annat runmaterial. Resultatet innebär en nyläsning och -tolkning av en av inskriftens rader. Läsningen är kuþaskaki faþi sunuR naut smiþa kata uif siþaR un…, vilket tolkas Goða-Skeggi fáði. Sonr naut smíða Káta. Víf síðarr unn[i] och översätts ’Gode-Skägge (det vill säga godens eller godarnas Skägge) ristade. Sonen fick (eller fick nytta av) Kåtes smiden. Hustrun förunnade (eller gav lov) senare’. Sonen bör vara Kåtes son och hustrun Kåtes hustru. Möjligen är Skägge identisk med Kåtes son. Förleden Gode- är troligen samma ord som fvn. goði ’hednisk präst’. Inskriften är förmodligen en minnesinskrift över den döde Kåte, samt en manifestation av en betydelsefull händelse kopplad till att de föremål som nämns byter ägare.

Occurrence des résidus et contaminants chimiques dans les miels produits et consommés au Liban : développement et standardisation de méthodes de dépistage adaptées : application aux résidus d'antibiotiques / Occurrence of chemical contaminants and residues in honey produced and consumed in Lebanon : development and standardization of a screening method for the determination of antibiotic residues

El Hawari, Khaled 12 December 2016 (has links)
Une nouvelle méthode, simple et rapide, a été développée pour isoler dans le miel différents antimicrobiens usuellement recherchés en contrôle sanitaire et appartenant à quatre classes différentes: les sulfamides, les tétracyclines, les macrolides et lincosamides associés et les aminoglycosides. Ces molécules antimicrobiennes sont analysées par chromatographie liquide couplée à la spectrométrie de masse en tandem (CL-SM/SM) après avoir été extraites de l’échantillon de miel par une méthode d’extraction unique. Afin de définir les conditions optimales de séparation et de détection, l’influence de la nature et de la concentration d’un agent d’appariement d’ions tel que le HFBA ou le PFPA, introduit dans la phase mobile, a pu être évaluée sur une colonne analytique en chromatographie de phase inversée de type C18. Plusieurs paramètres ont été pris en compte et étudiés lors de l’élaboration de la méthode d’extraction tels que la nature du solvant d’extraction, le pH, l’étape d’hydrolyse acide, l’efficacité de l’extraction par ultrasons et enfin la purification de l’extrait avant injection. La méthode développée a ensuite été validée suivant les recommandations de la Décision de la Commission Européenne (CE) No 2002/657 puis a subi une étape de validation supplémentaire en participant à une comparaison inter-laboratoire organisée sur des matériaux de miel contaminés et gérée par un organisme extérieur accrédité suivant la norme ISO17043. Par la suite, une démarche de transfert de la méthode analytique validée en CL-SM/SM a été mise en place pour son utilisation en chromatographie liquide couplée à la spectrométrie de masse à haute résolution (CL-SMHR). Une validation de cette démarche a été menée par l’application d’une étude statistique descriptive basée sur la notion de profil d’exactitude. Finalement, un programme expérimental de surveillance a été entrepris sur une série d’échantillons de divers miels collectés sur des marchés locaux pour tester la qualité des produits commercialisés au Liban. Contrôlés au regard de leur contamination en résidus d’antimicrobiens en CL-SM/SM parmi la trentaine de molécules prédéfinies dans l’étude, la positivité et/ou la non-conformité de certains échantillons ont pu être confirmées par l’utilisation de la CL-SMHR. / A new, simple and rapid method has been developed for the determination of multiclass antimicrobial residues in honey (sulfonamides, tetracyclines, macrolides, lincosamides and aminoglycosides). All the compounds were extracted from honey within single extraction method and analyzed by liquid chromatography - tandem mass spectrometry (LC-MS/MS) operating in positive electrospray ionization mode. In our study, we examined the behavior of volatile perfluorinated carboxylic acids (HFBA and PFPA) used as ion-pairing reagents for the separation of multiclass of antibiotic residues by reversed phase Zorbax SB C18 column. Furthermore, the extraction and clean-up steps were investigated and optimized by using ultrasonic-assisted extraction and dispersive solid phase extraction (d-SPE). Different parameters affecting the extraction efficiency including type of solvent, pH, breaking efficiencies of N-glycosidic linkage by hydrochloric acid, ultrasonic extraction and its duration compared to shaking technique, along with dispersive SPE clean-up were examined prior sample injection. The method was then validated according to European Commission Decision (EC) No 2002/657. Furthermore, the method was tested for its validity through participation in proficiency testing scheme organized by FAPAS for the analysis of tetracycline in honey. Afterwards, a transfer of the validated LC-MS/MS analytical method has been applied for the determination of antimicrobial residues in honey from low resolution to High Resolution Mass Spectrometry (HRMS). For that purpose, descriptive statistical approach was performed to assess the performance of the method based on simultaneous evaluation of the trueness and the intermediate precision. Finally, the method was applied for the determination of antimicrobial residues in honey collected from local markets at different regions in Lebanon. Positive samples were then analyzed by the LC-HRMS to confirm the presence of analytes detected by LC-MSMS.

Investigation of the Effects of Genistein and Fenretinide on Ovarian Cancer Cells

Azadi, Behnam 10 January 2012 (has links)
The effects of the fenretinide and genistein as single or combined drugs on ovarian cancer proliferation and viability were investigated. Hypothesis: Co-treatment with genistein will enable a lower dose of fenretinide to be effective in inhibiting the proliferation and survival of ovarian cancer cells. Methods: Low and high doses of genistein and fenretinide were tested on A2780s and A2780cp cells using trypan blue viable cell count, MTS assay. Results and conclusions: Unlike low doses of fenretinide, genistein had anti-proliferative effects on both cell lines. There were no additive or synergistic effects of the two compounds. Higher dose treatments induced anti-proliferative effects and apoptotic cell death in both A2780s and A2780cp cells, with a greater sensitivity of A2780s cells to both test compounds. Overall Conclusion: Genistein and higher doses of fenretinide similarly impair cell cycle progression and induce apoptosis. The anti-proliferative effects of genistein can be affected by co-treatment with fenretinide

Sm-Nd and C-isotope chemostratigraphy of Ordovician epeiric sea carbonates, midcontinent of North America

Fanton, Kerrie C. 04 January 2005
Interpreting and correlating epeiric sea sequences is key to understanding ancient marine environments. As a result, eNd, d13C and Sm/Nd profiles are developed as tools for interpreting epeiric sea carbonates. Previously, eNd and d13C profiles in epeiric sea carbonates have been used to study changes in the Nd isotope balance and C-cycle of adjacent ocean water. Instead, eNd, d13C and Sm/Nd profiles of Ordovician Midcontinent carbonates of North America demonstrate that fluctuations in sea level and depth are driving local changes in the eNd, d13C and Sm/Nd composition of epeiric seawater. <p> Dissolved Nd derived from the Transcontinental Arch, Taconic Highlands and the Iapetus Ocean determine the eNd composition of Midcontinent seawater. As sea level fluctuated, submergence of the Arch and an influx of Iapetus ocean waters adjusted the Nd isotope balance of epeiric seawater. As a result, eNd profiles can be used to track the submergence history of the Late Ordovician Midcontinent. Comparison of stratigraphic variations in carbonate Sm/Nd ratios with sea level curves, conodont paleoecology, and the eNd profiles also suggests that variations in Sm/Nd ratios are related to changes in depth. However, processes effecting Sm/Nd ratios in epeiric seas may be varied and require further investigation. <p> Sea level fluctuations and the waxing and waning of cool, nutrient rich, oxygen poor Iapetus waters onto the craton adjusted productivity and organic carbon burial rates on the Ordovician Midcontinent. Close to the Transcontinental Arch sea level rise caused an increase in organic carbon burial and productivity, while close to the Sebree Trough, and the influx of Iapetus waters, sea level rise caused a decrease in organic carbon burial and productivity. Differences in local C-cycling across a single epeiric sea encourage caution when using d13C profiles from epeiric sea carbonates to track changes in the C-cycle of adjacent oceans. <p> Because of their connection to sea level fluctuations, variations in the eNd, d13C and Sm/Nd profiles can also used to correlate Ordovician Midcontinent carbonates. However, the ability to correlate coeval strata using these profiles is limited by changes in depositional environment across the craton, which cause excursions to be absent, dampened, or magnified.
