In this paper we address a supply vessel planning problem arising in servicing oil and gas offshore installations. Supply vessels provide offshore installations with necessary supplies on periodic basis from offshore supply bases according to weekly sailing schedules. The execution of weekly schedules during the year is affected by weather conditions influencing on sailing time and service dura...

Introduction: Different neutron rich isotopes (Ti, Cr, Ni and Zr) display well documented isotopic heterogeneities between various meteorite groups and the Earth-Moon system [16]. The origin of these variations is not well understood. It has been suggested that the observed Ti isotope pattern in bulk solar system materials was generated by thermal events during solar system formation [2]. An al...

Copper (Cu) could be suitable to create anti-infective implants based on Titanium (Ti), for example by incorporating Cu into the implant surface using plasma immersion ion implantation (Cu-PIII). The cytotoxicity of Cu might be circumvented by an additional cell-adhesive plasma polymerized allylamine film (PPAAm). Thus, this study aimed to examine in vivo local inflammatory reactions for Ti6Al4...

conclusion the myocardial grayscale intensity, velocity and displacement can effectively reflect the situation of steiri in patients after cardiac operation, and ti (cvi) has a higher performance in discriminating between patients with and without steiri. background the timely diagnosis of presence or absence of reperfusion injury after cardiac operation is critical for the patient’s outcome. w...

n 1499, when portuguese explorer vasco da gama returned home after completing the first-ever sea voyage from Europe to India, he had less than half of his original crew with him— scurvy had claimed the lives of 100 of the 160 men. Throughout the Age of Discovery,1 scurvy was the leading cause of death among sailors. Ship captains typically planned for the death of as many as half of their crew ...

Titanium (Ti) has long been regarded as an inert and biocompatible metal, ideal for biomedical applications such as dental implants or joint replacements. However, concerns about the biocompatibility of Ti have lately arisen. Unfortunately, information on reliable Ti baseline physiological levels in blood and organ tissues is still pending and the real effects of physiological corrosion as oppo...

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...
