New substituted triazolopyrimidne derivatives were synthesized starting from 1,2,3-triazolo-4-carboxamide derivative. The N- and S-glycoside derivatives of the synthesized triazolopyrimidine ring system as well as their acyclic sugar analogs were also synthesized. The cytotoxicity and in vito anticancer evaluation of the prepared compounds have been assessed against three different human tumor ...

We describe a rare case of multiple coronary artery-left ventricular fistulas associated with apical hypertrophic cardiomyopathy in a 62 year asymptomatic old male admitted to our department for a perioperative evaluation of non cardiac surgery, already diagnosed for multiple coronary artery-left fistulae. He underwent transthoracic echocardiography and then to accelerated dipiridamole stress-e...

The new pyrrolo[3,4-c]pyridines and 2,7-naphthyridine derivatives have been synthesized. 4-Hydroxy-8-methyl-l-oxo-6-phenyl-1,2-dihydro-2,7-naphthyridine-3-carboxylic acid hydrazide (4) was the key intermediate for the synthesis of the novel derivatives of various chemical structures: Schiff bases, 1,3,4-oxadiazoles, pyrazoles, carbohydrazides, semi- and thiosemicarbazides. The structures of the...

Oxidative stress, a state characterized by imbalance between pro-oxidant molecules comprising reactive oxygen and nitrogen species, and antioxidant defences, has been found to play an important in poultry reproduction in both male and female Increasing evidence suggests that vitamin E plays an important role in normal reproduction in animals and humans, and vitamin E supplementation is now reco...

This work presents an electronic board for driving and control of High Intensity Discharge (HID) lamps and Light Emitting Diode (LED) lamps. The proposed electronic board is able to drive HID or LED lamps by means of a reconfigurable output. This feature allows using the ballast in lighting systems that currently use traditional discharge lamps, as well as keeping the same ballast when discharg...

In 2000, VITO initiated the Pegasus project to demonstrate the feasibility of remote sensing from a HALE UAV. Ultimately the HALE UAV platform will be equipped with a variety of light weight high resolution remote sensing instruments. The synergy of the onboard sensors thus allows continuous observations, irrespective of light or weather conditions. In a first phase a multi-spectral digital cam...

The PEGASUS High-Altitude Long-Endurance (HALE) Unmanned Aerial Vehicle (UAV) system has two major operational modes: (a) large-scale regional photogrammetric and environmental mapping and (b) near real time event monitoring. Given the concept of the HALE UAV camera design (decimetre resolution RGB), a massive data stream of about 0.5 to 1.0 TB/day is expected. The Central Data Processing Centr...
