Inbred lines derived from a strain called Sexi were analyzed for their abilities to repress P element-mediated gonadal dysgenesis. One line had high repression ability, four had intermediate ability and two had very low ability. The four intermediate lines also exhibited considerable within-line variation for this trait; furthermore, in at least two cases, this variation could not be attributed...

BACKGROUND & OBJECTIVE IS 6110 based typing remains the internationally accepted standard and continues to provide new insights into the epidemiology of Mycobacterium tuberculosis. The aim of the study was to characterize M. tuberculosis isolates obtained from different parts of India based on IS6110 element polymorphism using restriction fragment length polymorphism (RFLP) analysis. METHODS ...

Cut-and-paste (simple insertion) and replicative transposition pathways are the two classical paradigms by which transposable elements are mobilized. A novel variation of cut and paste, a two-step transposition cycle, has recently been proposed for insertion sequences of the IS3 family. In IS2 this variation involves the formation of a circular, putative transposition intermediate (the minicirc...

This study compared the biomechanics of 3 fixation techniques: bilateral pedicle screw (BPS) fixation, unilateral pedicle screw (UPS) fixation, and UPS supplemented with translaminar facet screw (UPS+TLFS) fixation. The study was conducted in an L3-L5 finite element model. Three different finite element models were created by adopting different fixation techniques after removal of the left L3-L...

We prove that if a group generated by a bireversible Mealy automaton contains an element of infinite order, its growth blows up and is necessarily exponential. As a direct consequence, no infinite virtually nilpotent group can be generated by a bireversible Mealy automaton. The study on how (semi)groups grow has been highlighted since Milnor’s question on the existence of groups of intermediate...

In engineering practice, longitudinal brace systems for column-braced are designed to resist both horizontal and vertical loads. previous experimental research on forces of intermediate height, only loads were considered. Hence, this paper presents a numerical simulation numerous subjected the simulation, second-order analysis was adopted, Monte Carlo method used incorporate randomness initial ...

This paper investigates the dynamics of velocity gradients for a spatially developing flow generated by a single square element of a fractal square grid at low inlet Reynolds number through direct numerical simulation. This square grid-element is also the fundamental block of a classical grid. The flow along the grid-element centreline is initially irrotational and becomes turbulent further dow...

in current work a comprehensive mechanism based on intermediate radical termination theory is assumed for raft polymerization of styrene over cumyl dithiobenzoate as raft agent. rate constants for addition (ka) and fragmentation reactions (kf) are set to 6×106 and 5×104 respectively, which lead to an equilibrium constant value of k = ka/kf = 1.2 x 102. moment equations method was used to model ...

background: xmn-1 polymorphism of y g globin gene ( hbg2 ) is a prominent quantitative trait loci (qtl) in β-thalassemia intermediate (β-ti). in current study, we evaluated frequency of xmn-1 polymorphism and its association with β-globin gene ( hbb ) alleles and hb f level in β-ti patients in sistan and balouchestan province, south-east of iran. methods: 45 β-ti patients were enrolled. hbb gen...

The need for interoperation and data exchange through the Internet makes XML a dominant standard language. Much work has been done on translating relational data into XML documents and vice versa. However, there is not an integrated method to combine them together as one technology for mass information transmission on the Internet. Furthermore, most XMLenabled database management systems can on...
