The growth and interdiffusion of Ti and Ni on a Mo( 110) surface have been studied by Auger electron spectroscopy (AES), low energy electron diffraction (LEED) and temperature programmed desorption spectroscopy (TPD). Ti grows layer-by-layer upon deposition on MO{ 110) at 115 K, whereas annealing multifaye~ of Ti to 900 K causes formation of Ti three-dimensional clusters. Submonolayer Ti on Mo(...

The objective of this study was to evaluate effects of baclofen, a γ-aminobutyric acid type B (GABAB) receptor agonist, injected into the nucleus of the solitary tract, on the Hering-Breuer inspiratory-inhibitory (Ti-inhibitory) and deflation reflexes in urethan-anesthetized adult Wistar rats ( n = 7). The Ti-inhibitory reflex was estimated from changes in peak amplitude of the integrated diaph...

Translation invariant (TI) single wavelet de-noising was developed by Coifman and Donoho and they show that TI is better than non-TI single wavelet de-noising. On the other hand, Strela et al. have found that non-TI multiwavelet de-noising gives better results than non-TI single wavelets. In this paper we extend Coifman and Donoho's TI single wavelet de-noising scheme to multiwavelets. Experime...

introduction: nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. the cause of the abnormal development of the pharyngeal arches in nager syndrome is unknown. it is also unclear why affected individuals have bone abnormalities in their arms and legs. nager syndrome is thought to have an autosomal recessive inheritan...

turner syndrome is one of the best known chromosome anomalies in human being, by an approximate incidence of 1/2500 female at birth. the cause is a chromosomal aberration, mainly with the karyotype 45, x. ninety six patients aged 6 to 26 years with short stature were studied for chromosomal anomalies. out of these 82 were phenotypically female and 14 phenotypically male. twenty seven showed abn...

Because of its excellent biocompatibility and low allergenicity, titanium has been widely used for bone replacement and tissue engineering. To produce a desirable composite with enhanced bone response and mechanical strength, in this study bioactive calcium phosphate (CaP) and gelatin composites were coated onto titanium (Ti) via a novel urease technique. The cellular responses to the CaP/gelat...

Calixarene-Ti complexes were grafted onto SiO2 (0.18-0.24 Ti nm-2) to form isolated and accessible Ti centers persistently coordinated to multidentate calixarene ligands. Grafted Ti-tert-butylcalix[4]arenes gave Ti K-edge absorption spectra with pre-edge features at 4968.6-4968.9 eV, independently of Ti surface density and of their use in epoxidation catalysis. The structure and reactivity of g...

titanium aluminide and its alloys have been utilized in automotive, aerospace and power industries because of their specific properties such as low density (~ 4 g/cm3), high melting temperature (~ 1460 °c) and excellent high-temperature strength. ti-48al intermetallic compound and its alloys with 1.5, 3 and 5 at.%mn were produced with mechanical alloying of elemental powders for 50 hours. the p...

Let us say that an element of a given family A of subsets of R can be reconstructed using n test sets if there exist T1, . . . , Tn ⊂ R such that whenever A,B ∈ A and the Lebesgue measures of A∩ Ti and B ∩ Ti agree for each i = 1, . . . , n then A = B. Our goal will be to find the least such n. We prove that ifA consists of the translates of a fixed reasonably nice subset of R then this minimum...

The adsorption and dissociation of NH(3) on the clean and hydroxylated TiO(2) rutile (110) surfaces have been investigated by the first-principles calculations. The monodentate adsorbates such as H(3)N-Ti(a), H(2)N-Ti(a), N-Ti(a), H(2)N-O(a), HN-O(a), N-O(a) and H-O(a), as well as the bidentate adsorbate, Ti-N-Ti(a) can be formed on the clean surface. It is found that the hydroxyl group enhance...
