A total of 69 gram-positive, catalase-negative strains isolated from Inner Mongolia traditional meat sausages were characterized in respect to their technological properties, including acid production, salt and nitrite tolerance, gas, slime and H2S production, hydrolysis of arginine and biogenic amine production. All of the isolated strains decrease the pH below 5.0 after 24h of cultivation. All isolates are able to grow with 6.5% NaCl or with 150mg L-1NaNO2and 51 isolates are able to grow with 10% NaCl. All isolates don’t produce gas and slime. 54 isolates don’t produce H2S. 23 isolated strains don’t produce NH3 from arginine, and 40 isolates don’t produce biogenic amine. Consolidation of these results, 8 strains show the best technological properties to be used as starter culture for sausage production. The bacterial selected are then subjected to biochemical tests using the API 50 CH and they are identified as 6 Lactobacillus planarum and 2 Lactobacillus curvatus.

In the 2009 version of the ASME BPV Code, a set of new design fatigue curves were proposed to cover the various steels of the code. These changes occurred in the wake of publications [1] showing that the mean air curve used to build the former ASME fatigue curve did not always represent accurately laboratory results. The starting point for the methodology to build the design curve is the mean air curve obtained through laboratory testing: coefficients are then applied to the mean air curve in order to bridge the gap between experimental testing and reactor conditions. These coefficients on the number of cycles and on the strain amplitude are equal to 12 and 2 respectively in the 2009 ASME BPV code, using the mean air curve proposal from NUREG/CR-6909 [1]. Internationally, with the same mean air curve, other proposals have emerged and especially in France [2]-[3] where a consensus seems to be reached on the reduction of the coefficient on strain amplitude. This paper provides statistical analyses of the experimental data obtained in France at high-cycle for austenitic stainless steels. It enables to bring arguments for the selection of a coefficient on strain amplitude in the French RCC-M code, where less scatter on the data is witnessed due to fewer material grades.

Abstract This paper investigates the strategies involved in gender assignment in Spanish-Basque mixed Determiner Phrases (DPs) with a gendered Spanish determiner (el M /la F) and a Basque ungendered noun. Previous studies on Spanish-Basque mixed DPs have revealed conflicting results regarding the determining factor affecting gender assignment, namely, phonological ending vs. analogical gender. We designed a forced-switch elicitation task in order to elicit mixed DPs with a Spanish determiner and a Basque noun (controlled for both phonological vs. analogical cues). Thirty highly proficient Spanish-Basque bilinguals with different profiles and socio­linguistic backgrounds participated in the study. Three cues were significant in the selection of the Spanish M/F determiner: the analogical gender and two phonological cues, the word ending and the root ending of the Basque noun. Further statistical analyses revealed participants’ L1 as a strong factor in the variability attested: bilinguals with Spanish as (one of) their L1(s) rely predominantly on the analogical criterion, whereas speakers with only Basque as L1 follow mainly the phonological criterion. Overall, this study provides an explanation for the previous conflicting results and highlights the fact that bilinguals may use different strategies depending on their bilingual profile and the morpho-phonological properties of the languages in contact.

Software development methodology refers to a standardised, documented methodology which has been used before on similar projects or one which is used habitually within an choice of software development method, and applying the right method for the job. From this perspective, the portlet development encounters new circumstances which affect the chosen method. A portal development manager must be aware of the technological properties and constraints, because there development and deployment processes. These issues are not well defined yet; there is no proven methodology for driving portal projects. This article provides discussion of practical approaches to the resolution of development issues and risks in portal environment. The discussed topics include implementation of portals in enterprise environment, portlet applications’ high availability, portlet disaster recovery, and cost of portlet deployment. An attempt is made to forecast future trends in portlet technology at the end of the article, as well as suggest the directions for the flexible selection of methodologies and managerial experience suited to the portal development.

In “A Robust Transformation Procedure,” Martin and Vanberg (2007, hereafter MV) propose a new method for rescaling the raw virgin text scores produced by the “Wordscores” procedure of Laver, Benoit, and Garry (2003, hereafter LBG). Their alternative method addresses two deficiencies they argue exist with the transformation of virgin text scores proposed by LBG: First, that the LBG transformation is sensitive to the selection of virgin texts, and second, that it distorts the reference metric by failing to recover the original reference scores when reference texts are scored and transformed as if they were virgin texts. Their proposed alternative is “robust” in the sense that it avoids both shortcomings. Not only is MV's transformation a welcome contribution to the Wordscores project but also the critical analysis on which it is based brings to light a number of assumptions and choices that face the analyst seeking to estimate actors' policy positions using statistical analyses of the texts they generate. When first describing the possibility of rescaling the raw virgin text estimates, we emphasized that ourparticular approach to rescaling is not fundamental to our word-scoring technique but, rather, is a matter of substantive research design unrelated to the validity of the raw virgin text scores… Other transformations are of course possible. (LBG, 316)To explore more fully into the assumptions and choices behind alternative transformations and the research designs which motivate them, we offer the following comments.

The purpose of this study was to quantify the extent to which the presence or absence of cancer in endoscopically evaluable regions of the supraglottic larynx predicted occurrence in a region less easy to visualize but of critical importance to the nature of treatment. Histologic findings from 32 specimens were subjected to two separate statistical analyses. In the first analysis, the presence of cancer on the floor of the ventricle was the best predictor of tumor below this level. The combination of variables with the best correlation was cancer on the floor of the ventricle and in the vestibular folds. In the second analysis, involvements of the deep structures in the aryepiglottic folds and in the infrahyoid epiglottis were the only significant predictors of tumor extending to the preepiglottic space. The results suggest that such statistical analyses may provide guidelines for selection of treatment.
