acute lymphoblastic leukemia (all) is a malignant disorder of lymphoid precursor cells, which could be classified according to morphological and cytochemical methods as well as immunophenotyping. twenty patients with all, who had been referred to the children's medical center hospital, during the year 2007, were enrolled in this study in order to evaluate the morphologic and immunophenotypic pr...

two poly(oxyethylene) derivatives 1.10-bis(2'-benzoic acid)-1,4,7,1-tetradecane (l1) and 1,7-bis(2'-benzoic acid)-1,4,7-trioxaheptane (l2) were used as suitable ionophores for the preparation of potassium-selective pvc-membrane electrodes. the resulting electrodes based on l1 and l2 exhibit linear responses to the activity of k+ ions within the concentration ranges of 3.1´10-5 -2.7´10-2 m and 2...

Communication strategies (CSs) are systematic attempts by language learners to encode or decode meaning in a target language in situations where the appropriate target language rules have not been formed. Based on this view, communication strategies can be seen as compensatory means for making up for linguistic deficiencies of second or foreign language learners. Within the conceptual framework...

second language acquisition (sla) always happens when the learners live and have contact with the native speakers of a second language. although this study investigates learning english by ten native children of farsi, the authors try to simulate the second language acquisition environment. the research deals with the initial state and further development in the child second language learning o...

The time course of cross-script translation priming and repetition priming was examined in two different scripts using a combination of the masked priming paradigm with the recording of event-related potentials (ERPs). Japanese-English bilinguals performed a semantic categorization task in their second language (L2) English and in their first language (L1) Japanese. Targets were preceded by a v...

Although research on multilingualism has revealed continued neuroplasticity for language-learning beyond what was previously expected, it remains controversial whether and to what extent a second language (L2) acquired in adulthood may induce changes in the neurocognitive processing of a first language (L1). First language (L1) attrition in adulthood offers new insight on neuroplasticity and th...

Kakoi, Masaki Ph.D., Purdue University, May 2015. Design of Transfers from EarthMoon L1/L2 Libration Point Orbits to a Destination Object. Major Professor: Kathleen C. Howell. Within the context of both manned and robotic spaceflight activities, orbits near the Earth-Moon L1 and L2 libration points could support lunar surface operations and serve as staging areas for future missions to near-Ear...

The most obvious bimodal logic generated from unimodal logics L1 and L2 is their fusion, L1 ⊗L2, axiomatized by the theorems of L1 for 1 and of L2 for 2, and by the rules of modus ponens, substitution and necessitation for 1 and for 2. Shehtman introduced the frame product L1×L2, as the logic of the products of certain Kripke frames. Typically, L1 ⊗ L2 ( L1 × L2, e.g. S4⊗ S4 ( S4× S4. Van Benth...
