Sud4science, de l’acquisition d’un grand corpus de SMS en français à l’analyse de l’écriture SMS
Rachel Panckhurst,Catherine Détrie,Cédric Lopez,Claudine Moïse,Mathieu Roche,Bertrand Verine 고려대학교 응용문화연구소 2013 에피스테메 Vol.0 No.9
Dans le cadre de cet article, on expose le déroulement du projet sud4science (www.sud4science.org). En premier lieu, on décrit la phase d’acquisition des données en provenance des SMS et du questionnaire, avant d’aborder les étapes successives d’anonymisation, de transcodage et d’annotation optionnelle. Ensuite, on présente les analyses (socio-)linguistiques des pratiques scripturales de l’écriture SMS (eSMS) qui ont débuté, ainsi que celles prévues à court et à moyen terme. This article describes the sud4science project (www.sud4science.org). Firstly, the authors present the acquisition phase of both SMS data and questionnaire data. Secondly, they explain anonymisation techniques, transcoding and optional annotation phases. Finally, they propose preliminary (socio-) linguistic analyses of scriptural usage of SMS writing, and they also indicate those that are planned in the foreseeable future.
Electronic transport study of PbSe pellets prepared from self-assembled 2D-PbSe nanostructures
E. Díaz-Torres,A. Flores-Conde,A. Avila-García,M. Ortega-Lopez 한국물리학회 2018 Current Applied Physics Vol.18 No.2
This work presents a study of the electronic transport properties of PbSe pellets fabricated starting of PbSe nanostructures that exhibited a flake-like 2D morphology, which were synthesized by the coprecipitation method. Seebeck coefficient measurements revealed that the PbSe sample displays ntype conductivity, a maximum Seebeck coefficient of 512.6 mV/K around 380 K, and that the carriers scattering is dominated by acoustic and optical phonons. The Fermi level dependence on the temperature and the band gap energy are also reported. Interestingly, size-dependent confinement effects due probably to the reminiscent PbSe 2D character could be evidenced.

Infertility is a concern for couples, families and society. In almost half of the cases, it is due to male infertility. This infertility, in developing countries like Benin, often cured by the use of medicinal plants. This study aimed to enlist knowledge about medicinal plants used in the treatment of male infertility in southern Benin. An ethnomedicinal investigation has been conducted in southern Benin by questioning traditional healers and market herbalists using the method of semi-structured interview. Ethnopharmacological data has been analyzed by ethnobotanical indices such as informant consensus factor (ICF), frequency of citation for each plant species and contribution of each plant to drug recipes. 90 respondents including 36 market herbalists and 54 traditional healers participated in this study. Data collected allowed us to list 60 plant species belonging to 56 genera and 38 botanical families. Informants had a high degree of consensus (ICF = 0.58) on plants used for treatment of male infertility. The most plants cited by market herbalists were Garcinia kola (10.09%), Cissus populnea (10.09%), Carpolobia lutea (07.40%) and the parts of plants most used were roots and fruits. For traditional healers, Garcinia kola (10.15%), Cyperus esculentus (06.09%), Citrus aurantiifiola (06.09%) were the most plants cited and parts of plants the most used were leaves and roots. This study provided a list of medicinal plants used for the treatment of male infertility in southern Benin. Further pharmacological and toxicological studies will assess the therapeutic efficacy of these medicinal plants.
Electrochemical Study of Three Stainless Steel Alloys and Titanium Metal in Cola Soft Drinks
Peralta-Lopez, D.,Sotelo-Mazon, O.,Henao, J.,Porcayo-Calderon, J.,Valdez, S.,Salinas-Solano, G.,Martinez-Gomez, L. The Korean Electrochemical Society 2017 Journal of electrochemical science and technology Vol.8 No.4
Stainless steels and titanium alloys are widely used in the medical industry as replacement materials. These materials may be affected by the conditions and type of environment. In the same manner, soft drinks are widely consumed products. It is of interest for dental industry to know the behavior of medical-grade alloys when these are in contact with soft drinks, since any excessive ion release can suppose a risk for human health. In the present study, the electrochemical behavior of three stainless steel alloys and pure titanium was analyzed using three types of cola soft drinks as electrolyte. The objective of this study was to evaluate the response of these metallic materials in each type of solution (cola standard, light and zero). Different electrochemical techniques were used for the evaluation of the alloys, namely potentiodynamic polarization, linear polarization, and open-circuit potential measurements. The corrosion resistance of the stainless-steel alloys and titanium in the cola soft drinks was provided by the formation of a stable passive film formed by metal oxides. Scanning electron microscopy was used as a complementary technique to reveal corrosion phenomena at the surface of the materials evaluated.

The tejocote (Crataegus spp.) is a tree considered to be native to Mexico. The aim of this study was to identify the causal agent of tejocote rust in the State of Puebla. Tejocote fruits were sampled in 2012 and 2013. The fungus was studied morphologically using light and scanning electron microscopy and molecularly using phylogenetic analysis of 18S and 28S rDNA genes. The fungus was identified as Gymnosporangium clavipes on tejocote fruits. To our knowledge, this is the first confirmed report of Gymnosporangium clavipes Cooke & Peck affecting Crataegus mexicana var. Chapeado and C. gracilior in Puebla Mexico.

Objective: This experiment was designed to evaluate the effect of supplementation with soybean or canola oil on milk production and the composition of long chain fatty acids as well as weight changes in the goats and their kids. Methods: Thirty nine mulitparous crossed Alpine×Nubian goats (initial body weight [BW] 43.5±1.7 kg) from the day of parturition were assigned to the treatments: grazing control (n = 15); grazing plus 20 mL/goat/d of supplemental soybean oil (n = 12); and grazing plus 20 mL/goat/d of supplemental canola oil (n = 12) from November 26, 2014 to March 7, 2015. The planned contrasts were: CI (control vs supplemented with oils); CII (soybean vs canola oil) to compare the treatment effects. Results: The vegetable oil supplementation reduced weight losses in lactating goats (CI: –0.060 vs 0.090 kg/d; p = 0.03) but did not improve milk production or affect kids’ growth. The content of C4, C6, C8, C10, C11, C14, and C18:1n9t in the milk was increased (p<0.05) with respect to control. However, C12, C14, C16, C18, C18:1n9c, C18:2n6c, and C18:3n3 were reduced (p<0.05) in supplemented goats. Conjugated linoleic acid (CLA) was increased (p<0.05) in goats supplemented with oils compared to the control group. Conclusion: Supplementation with 20 mL/d of soybean or canola oil did not affect milk production or kids’ performance; however, it increased CLA concentration and reduced the reduced weight losses in lactating goats.
Suppression of cooling by strong magnetic fields in white dwarf stars
Valyavin, G.,Shulyak, D.,Wade, G. A.,Antonyuk, K.,Zharikov, S. V.,Galazutdinov, G. A.,Plachinda, S.,Bagnulo, S.,Machado, L. Fox,Alvarez, M.,Clark, D. M.,Lopez, J. M.,Hiriart, D.,Han, Inwoo,Jeon, Young Nature Publishing Group, a division of Macmillan P 2014 Nature Vol.515 No.7525
Isolated cool white dwarf stars more often have strong magnetic fields than young, hotter white dwarfs, which has been a puzzle because magnetic fields are expected to decay with time but a cool surface suggests that the star is old. In addition, some white dwarfs with strong fields vary in brightness as they rotate, which has been variously attributed to surface brightness inhomogeneities similar to sunspots, chemical inhomogeneities and other magneto-optical effects. Here we describe optical observations of the brightness and magnetic field of the cool white dwarf WD 1953-011 taken over about eight years, and the results of an analysis of its surface temperature and magnetic field distribution. We find that the magnetic field suppresses atmospheric convection, leading to dark spots in the most magnetized areas. We also find that strong fields are sufficient to suppress convection over the entire surface in cool magnetic white dwarfs, which inhibits their cooling evolution relative to weakly magnetic and non-magnetic white dwarfs, making them appear younger than they truly are. This explains the long-standing mystery of why magnetic fields are more common amongst cool white dwarfs, and implies that the currently accepted ages of strongly magnetic white dwarfs are systematically too young.
