This paper describes a low-cost SDR implementation and performance evaluation of an IEEE 802.15.4 (ZigBee) baseband transceiver realized with a programmable Transport Trigger Architecture (TTA) Application Specific Processor (ASP). The SDR implementation has advantages over current System-on-Chip (SOC) implementations in terms of programmability and flexibility. The transceiver is designed for ...

Green liquor (Na2S + Na2CO3, GL) pretreatment is an effective pathway for improving the enzymatic digestibility of lignocellulosic biomass for the production of bioethanol. In this work, GL was employed as a pretreatment to enhance the enzymatic saccharification of poplar. During pretreatment, the increase of H-factor and TTA charge resulted in enhanced delignification and increased degradation...

HIV-1 envelope glycoproteins (Envs) mediate virus entry by fusing the viral and target cell membranes, a multi-step process that represents an attractive target for inhibition. Entry inhibitors with broad-range activity against diverse isolates of HIV-1 may be extremely useful as lead compounds for the development of therapies or prophylactic microbicides. To facilitate the identification of su...

Control elements of the tetracycline-resistance operon encoded in Tn10 of Escherichia coli have been utilized to establish a highly efficient regulatory system in mammalian cells. By fusing the tet repressor with the activating domain of virion protein 16 of herpes simplex virus, a tetracycline-controlled transactivator (tTA) was generated that is constitutively expressed in HeLa cells. This tr...

the extraction of gadolinium (gd) from perchlorate and nitrate media in 1,2-dichloroethane(c2h4cl2), carbon tetrachloride (ccl4) and chloroform (chcl3) by mixtures of 2-thenoyltrifluoroacetone (htta) and a crown ether benzo-15-crown-5 (b15c5) is investigated.the composition of the extracted species is determined as gd(tta)3.nb15c5 (n=1 in nitratemedium and n=2 in perchlorate medium). the values...

Flexible luminescent polymer films were obtained by doping europium(III) complexes in blends of poly(methyl methacrylate) (PMMA) and the ionic liquid 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [C6mim][Tf2N]. Different europium(III) complexes have been incorporated in the polymer/ionic liquid matrix: [C6mim][Eu(nta)4], [C6mim][Eu(tta)4], [Eu(tta)3(phen)] and [choline]3[Eu(dpa...

Key Points • Palpation of functional cranial tibial thrust instability during weight-bearing is used to assess knee stability preand post-operatively. • Variation in radiographic landmarks to determine stifle flexion angle (SFA) leads to variable TTA cage size recommendations. Use of the Long Axes Method leads to larger advancement recommendations than Kinematic or Eminence Methods. • Variation...

Temporal triangular alopesi (TTA), doğumda ya da erken çocukluk çağında ortaya çıkan, sıklıkla frontotemporal bölgede unilateral bilateral yerleşim gösteren, asemptomatik, skar bırakmayan lokalize saç kaybıdır. Etkilenen tam bir kaybı olabilir ince vellüs tüyleri görülebilir. Alopesi genellikle kalıcıdır. Çoğunlukla areata ile karıştırılmasından dolayı literatürde bildirilen TTA olguları az say...

The subject of this study was to investigate lactic acid bacteria (LAB) and yeasts microbiota traditional sourdough (n = 36) indicate characteristics enriched that is produced from combinations isolates. A total 60 LAB 40 were identified by matrix-assisted laser desorption ionisation-time-of-flight mass spectrometry (MALDI-TOF MS) analysis. dominant microflora Lactobacillus brevis (43.33%), Ped...

Two novel p-conjugated small molecules based on the electron-deficient diketopyrrolopyrrole (DPP) and the electron-rich fused tetrathienoacene (TTA) frameworks are synthesized and characterized. As verified in the bandgap compression of these chromophores by electrochemistry and density functional theory (DFT) computation, these DPP-TAA derivatives exhibit substantial conjugation and ideal MO e...
