to enrich our understanding of the attitudinal/motivational basis of foreign language learning at junior high school level, this study investigated the students’ status of l2 motivation, the relationship between motivational factors, and the possibility of predicting their motivated learning behavior in light of dörnyei’s (2005, 2009) theory of l2 motivational self system. to this end, 1462 jun...
In the human spine, it is well known that facet joints play a significant role in load transmission and providing stability. It has also been hypothesized to be one of most probable sources of low back pain. Experimental determination of the load-bearing role of lumbar intervertebral joints, such as the facets joints, under axial compression has not been a straightforward task. In this study, t...
PURPOSE The purpose of this study was to evaluate and compare the biomechanical behavior of the lumbar spine after posterior decompression with the spinous process osteotomy (SPiO) technique or the conventional laminectomy (CL) technique using a finite element (FE) model. MATERIALS AND METHODS Three validated lumbar FE models (L2-5) which represented intact spine and two decompression models ...
RNA-protein cross-linked complexes were isolated and purified to obtain precise data about RNA-protein contact sites in the 50 S ribosomal subunit of Escherichia coli. N-terminal microsequencing and matrix-assisted laser desorption ionization MS were used to identify the cross-linking sites at the amino acid and nucleotide levels. In this manner the following contact sites of five ribosomal pro...
Four synthetic peptides (Peptidyl MIMs; Demeter Biotechnologies, Inc.) were evaluated for their in vitro activity against Acholeplasma laidlawii. Fifty percent effective concentration values ranged from 1 to 15 microM. Three of these compounds are more lethal than cecropin B against A. laidlawii.
A tandem solar cell device whose sub-cells are fabricated exclusively from small molecules (SMs) through both solution-processed and vacuum-processed deposition techniques is described. The front sub-cell's active layer consists of a bulk heterojunction (BHJ) DPP(TBFu)2:PC70BM device while the back cell has a typical bilayer structure employing a 2,4-bis[4-(N,N-diisobutylamino)-2,6-dihydroxyphe...
This paper shows that when the Riemannian metric on a contact manifold is blown up along the direction orthogonal to the contact distribution, the corresponding harmonic forms rescaled and normalized in the L2-norms will converge to Rumin’s harmonic forms. This proves a conjecture in Gromov [11]. This result can also be reformulated in terms of spectral sequences, after Forman, Mazzeo-Melrose. ...
Abstract This study utilizes social network analysis to characterize a typology of abroad sojourner experience, detailing the relationship experience types second language (L2) proficiency growth and program design. In contrast with previous research, performs quantitative structural compositional features identify networks. Participants were 30 L2 Spanish learners from five US-based semester-l...
An elliptic Fourier integral operator of order 0, associated to a homogeneous canonical diffeomorphism, on a compact manifold is Fredholm on L2. The index may be expressed as the sum of a term, which we call the contact degree, associated to the canonical diffeomorphism and a term, computable by the Atiyah-Singer theorem, associated to the symbol. The contact degree is shown to be defined for a...
