PURPOSE Total knee arthroplasty (TKA) accompanies the risk of bleeding and need for transfusion. There are several methods to reduce postoperative blood loss and blood transfusion. One such method is using tranexamic acid during TKA. The purpose of this study was to confirm whether tranexamic acid reduces postoperative blood loss and blood transfusion after TKA. MATERIALS AND METHODS A total ...
Abstract—It is a major challenge to build a bridge superstructure that has long-term durability and low maintenance requirements. A solution to this challenge may be to use new materials or to implement new structural systems. Fiber Reinforced Polymer (FRP) composites have continued to play an important role in solving some of persistent problems in infrastructure applications because of its hi...
Resourcesat-1 LISS-IV Mx satellite imagery was used for detailed geomorphological and hydrogeological study of Karawan watershed. For morphometric analysis, ASTER data was used for preparing digital elevation model and GIS was used in evaluation of linear, areal and relief aspects of morphometric parameters. Watershed boundary, flow accumulation, flow direction, stream ordering; and contour, sl...
In this study, we report the synthesis and characterization of three novel "push-pull" chromophores, in which multiple phenylenevinylene units are endcapped by ferrocene as donor units and malonate moieties as acceptor units. These chromophores have spectroscopic and electrochemical characteristics which consistently change according to the extension of the conjugated bridge, thus to the variat...
When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
Studies on the spin distribution in the radical state of anthracene-a bridgeviologen supermolecules with different bridge units are reported. Electronnuclear double resonance experiments (ENDOR) were performed on electrochemically reduced molecules. Proton hyperfine coupling constants at different molecular sites were obtained and are discussed in detail. The experimentally determined values ar...
Consider a connected undirected graph G =< N , E >, where N is the set of n nodes, and E is the set of e edges. Without loss of generality, I assume N to be {1, 2, . . . , n}. An edge (i, j) ∈ E is a bridge of G if the removal of (i, j) disconnects G. Clearly, the removal of a bridge increases the number of connected components of a graph by one. The bridge-connected components problem consists...
In this paper, we discuss the split band code-excited linear prediction (SB-CELP) speech coder which employs an iterative version of the harmonic sinusoidal coding algorithm to encode the periodic contents of speech signal. Speech spectrum is split into two frequency regions of harmonic and random components and a reliable fundamental frequency is estimated for the harmonic region using both sp...
The title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)](n), is composed of one-dimensional linear chains running parallel to the a axis. In the chain, trans-[Cu(imidazole)(2)](2+) units are sequentially bridged by bis-bidentate oxalate ligands, resulting in an octa-hedral CuO(4)N(2) donor set. The Cu⋯Cu separation through the oxalate bridge is 5.620 (5) Å. Both the Cu atoms and the C-C bond of the ...
