Streszczenie:
To contribute to the valorization of Corchorus plants, fifteen (15) communities in Côte d'Ivoire have been visited and 432 participants were selected, during an ethnobotanical survey. This survey helped us to identify four (4) different species of Corchorus which are: C. aestuans, C. lobatus, C. olitorius and C. tridens. These different species are grown by farmers in general and also by farmers of vegetables and foods crops. In Côte d'Ivoire these plants are called “Kroala”. Kroala is the name given by Baoulé people from the centre part of Côte d’Ivoire. Krola can be used as main ingredient in the cooking of soups and it can also be used as medicinal plant. At food level, the leaves of different species of Corchorus are used in the cooking of soups for several meals throughout the country. At ethnomedicinal level, these different plant species are used in the treatment of several pathologies such as anemia, constipation... For instance, leaves, roots, leafy stems and seeds of these plant species are used to make several monospecific drugs recipes. For the benefits brought by Corchorus plants to people, the growing of these plants must be encouraged throughout the country.

Streszczenie:
The titanium reduction from titanium tetrachloride (TiCl4) by molten magnesium pool, called the Kroll process, is regarded as a well-known process for the commercial-scale production of titanium sponge. Purified titanium tetrachloride vapor reduced by magnesium, forms sponge titanium with generating excessive heal. The heal transfer phenomena in a Kroll reactor should be thoroughly understood for productivity and quality enhancement. In this work, a computational modeling method to describe the thermal behavior in the TiCl4 reduction reactor was investigated and validated with the measured temperature distribution in a 500kg titanium sponge-capacity pilot-scale reactor in terms of various reduction ratios. The approach model for heat flow phenomenon in a reduction reactor could be utilized as a tool to predict the influence of operating process parameters on the optimization of Kroll process.

Streszczenie:
The main purpose of the work described in this paper is to examine the extent to which the L2 developmental changes predicted by Kroll and Stewart's (1994) Revised Hierarchical Model (RHM) can be understood by word association response behaviour. The RHM attempts to account for the relative “strength of the links between words and concepts in each of the bilingual's languages” (Kroll, Van Hell, Tokowicz & Green, 2010, p. 373). It proposes that bilinguals with higher L2 proficiency tend to rely less on mediation, while less proficient L2 learners tend to rely on mediation and access L2 words by translating from L1 equivalents. In this paper, I present findings from a simple word association task. More proficient learners provided a greater proportion of collocational links, suggesting that they mediate less when compared to less proficient learners. The results provide tentative support for Kroll and Stewart's model.

Streszczenie:
DARPA instituted an Initiative in Titanium in 2003 to produce titanium, alternatively to the Kroll process, in a billet form for under $4/lb. This DARPA sponsored program has gone into Phase II consisting of utilizing ore/TiO2 as a feed. The TiO2 is carbothermically reduced to a suboxide-carbide (Ti:O:C) which is used anodically to resupply the titanium content in an electrolysis process that deposits titanium in a powder morphology. The deposited powder is uniquely stripped from the cathodes and harvested in a separate stream that permits continuous electrolytic processing to produce titanium at an estimated cost about ½ the Kroll process. Oxygen contents less than 500 ppm are achievable with particle sizes in the desired range for powder metallurgy applications. The process has been demonstrated on a continuous basis and is in the stage of scaling-up to 500 lbs/day.

Streszczenie:
In the last two decades there has been an explosion of research on bilingualism and its consequences for the mind and the brain (e.g., Kroll & Bialystok, 2013). One reason is that the use of two or more languages reveals interactions across cognitive and neural systems that are often obscured in monolingual speakers of a single language (e.g., Kroll, Dussias, Bogulski & Valdes Kroff, 2012). From this perspective, the interest in bilingualism is about developing a platform to ask questions about the ways that cognitive and neural networks are engaged during language use, in different learning environments, and across the lifespan. Another reason is that an emerging body of research on the consequences of bilingualism suggests that language experience changes cognition and the brain (e.g., Abutalebi, Della Rosa, Green, Hernandez, Scifo, Keim, Cappa & Costa, 2012; Bialystok, Craik, Green, & Gollan, 2009). Some of these changes have been claimed to produce cognitive advantages (see Bialystok et al., for a review of bilingual advantages and disadvantages).

Streszczenie:
Goldrick, Putnam and Schwarz (henceforth Goldrick et al.) base their computational account of code mixing on two premises, (1) that code mixing is subject to grammatical principles and (2) that “mental representations in bilingual speakers incorporate blends of structures from each language”. While there is copious evidence for the first premise, the second is far less well empirically supported. The authors imply that the second premise, the assumption of blend representations, is supported by Kroll & Gollan's (2014) review of speech planning in two languages, but this is not the case. Kroll & Gollan (2014:1) do indeed discuss evidence for the “parallel activation of the bilingual's two languages” but in terms of competition between alternatives rather than blended representations. The notion of blend is of course familiar to code-switching researchers from work on bimodal bilingual code mixing, as Goldrick et al. acknowledge, but here the term refers to “simultaneously produced English words and ASL signs” (Emmorey, Borinstein, Thompson & Gollan, 2008: 43).

Streszczenie:
A claim fundamental to the revised hierarchical model (Kroll & Stewart, 1994) was that concepts did not mediate backward translation, based on their findings of a category interference effect in forward translation in relatively fluent bilinguals but no category effect in backward translation. This study hypothesized that there was a category facilitation effect in L2-to-concept, which counterbalanced the category interference effect in concept-to-L1, resulting in an overall L2-to-L1 null category effect.In a novel English word-pair semantic comparison task, participants were presented with a sequence of English word-pairs, and judged which word's real-world referent was bigger in size. Results found a significant category facilitation effect in both L2-to-concept for young Chinese adults and L1-to-concept for young English adults when increasing the number of trials. The findings help explain why Kroll and Stewart's finding of an overall L2-to-L1 null category effect cannot be evidence against concept mediation in backward translation.

We present a simple generalization of the Kroll–Watson theorem for the potential scattering of electrons in a low-frequency laser field. This generalization includes the space–dependence of the radiation field in a nonrelativistic approximation and our results apply, in particular, if (i) the electron velocities are comparatively low so that terms of the order β2 may be neglected, and (ii) the laser intensities are relatively high, requiring the inclusion of the space–dependence of the radiation field.

Foram empregadas 8 estações fluviométricas com séries coincidentes de 14 anos cada, dando umas densidade aproximada de uma estação por 512 km2.As séries de vazões mínimas com d dias de duração obtidas por processo de média móvel foram correlacionadas com as características físicas e geomorfológicas da bacia hidrográfica, segundo modelo de Vogel & Kroll e analisadas estatisticamente.Os resultados apresentados permitiram concluir que das variáveis (área, índice de inclinação, constante de recessão) utilizadas para a estimativa das vazões mínimas com d dias de duração, somente área e índice de inclinação apresentaram significância, contrariando expectativas contidas na literatura em relação a constante de recessão. UNITERMOS: Modelos hidrológicos, regionalização, vazões mínimas. Gomes, B.M., Mattos, A. Estimate of physic and geomorphologic variables in the low flow responses. 2 ABSTRACT Many researchs were realized with the object to development hydrologic models to estimate statistically the low flows to places with or without records, through of the valiation of geomorphologic, physics and climatic parameters.In this work was utilized as variables of model proposed for Vogel & Kroll to estimate the low flows with 7, 14, 30, 60, 90, 120, 150 and 180 days of duration in the Jacare-Guaçu river- SP watershed. Concurrent 14 year time series of the stage recorder stations were employed, resulting in a density of nearly one station per 512 km2.The low flow series with d-days duration obtained by movel mean were correlated with the physical and characteristics of watershed, according model of Vogel & Kroll and analysed statistically.It was further observed from the variables used (area, inclination index, recession constant) for the estimation of the low flows means with d-days duration, only area and inclination index were significants, opposing expectancys contained in the literature, with relation to the recession constant.

Streszczenie:
Strumienie rozproszone są powszechnie wykorzystywane m.in. do gaszenia, chłodzenia oraz absorpcji substancji niebezpiecznych. W celu zoptymalizowania procesu, w którym wykorzystywane są rozpylacze, niezbędna jest wiedza na temat mikroi makrostruktury wytwarzanych przez nie strumieni. Parametry mikrostruktury strumienia rozpylonego, takie jak średnia średnica kropel czy widmo rozpylenia są uzależnione zarówno od cech konstrukcyjnych dysz, jak również ilości i ciśnienia przepływającej cieczy. W artykule przedstawiono wyniki badania mikrostruktury strugi generowanej przez wirową dyszę spiralną TF 6 NN o pełnym stożku zraszania. Badania były przeprowadzone przy różnych ciśnieniach zasilania i w czterech punktach strefy zraszania. Wybór tych punktów był poprzedzony wyznaczeniem rozkładów intensywności zraszania. Do określenia średnich średnic powierzchniowych kropel i widma rozpylenia wykorzystano metodę fotoelektryczną, zaś intensywność zraszania wyznaczono metodą kubełkową. Na podstawie przeprowadzonych badań udowodniono, że w strefie zraszania występują istotne dysproporcje w parametrach mikrostrukturalnych strumienia. Wykazano, że największa ilość wody wypływająca z badanej dyszy jest kierowana do głównego pierścienia zraszania, gdzie występują największe średnie średnice kropel. Zmiana ciśnienia zasilania dyszy nie powoduje istotnych zmian parametrów strugi w centralnej części strefy zraszania. W tym obszarze widmo rozpylenia, intensywność zraszania i średnia średnica kropel, niezależnie od ciśnienia zasilania, były zbliżone. Ponadto udowodniono, że w strefie położonej bezpośrednią pod dyszą odnotowuje się największy stopień rozpylenia strugi.

Streszczenie:
The renormalizable Kroll-Lee-Zumino field theory of pions and a neutral rho-meson is used to determine the scalar form factor of the pion in the space-like region at next-to-leading order. Perturbative calculations in this framework are parameter-free, as the masses and the rho-pion-pion coupling are known from experiment. Results compare favorably with lattice QCD calculations.

Streszczenie:
Literacy for bilinguals draws great interest from researchers and practitioners because it is central to success in school. In American schools, the ability to read in English is fundamental to mastering content area materials. Consequently, much of the literature on teaching bilinguals has concentrated on English (Carrell, Devine, & Eskey, 1988; Hudelson, 1989; Johnson & Roen, 1989; Kroll, 1990; Peregoy & Boyle, 1997; Reid, 1993).

Streszczenie:
As we shall show, for laser-assisted X-ray scattering by free electrons, a similar low-frequency theorem can be derived, as was found many years ago by Kroll and Watson, for potential scattering of electrons in a laser field. If quantum mechanical recoil effects are neglected, our renormalized cross-section formula becomes independent of Planck's constant and therefore must have a classical counterpart.
