Utjecaj zračnog prijevoza na kvalitetu uzoraka krvi

The aim of this study was to establish the impact of air transport on blood samples packaged with and without cooling elements and effect of outdoor temperature on sample quality. Venous samples from 38 blood donors in winter and 36 in summer were tested for hemolysis and complete blood count. One tube per subject was kept in controlled conditions at +4 °C. Two sets of tubes were sent by plane from Zagreb to Brussels, one with and one without cooling elements, and another two sets were sent to London following the same principle. Packages with cooling elements were stored in controlled warehousing conditions at airports (+2 °C to +8 °C), whereas packages without cooling elements were stored in ambient warehouse conditions. Data loggers were used for temperature monitoring. Our research revealed statistically significant differences in several hematologic parameters when comparing the samples stored in controlled laboratory conditions and those transported by plane. These differences were more pronounced in the samples transported during the summer. Transport conditions without cooling elements had additional negative impact on the sample quality. Transport of samples using cooling elements and controlled warehousing conditions at airports are sometimes not sufficient to maintain laboratory storage conditions.Cilj ovog istraživanja bio je utvrditi utjecaj zračnog prijevoza na uzorke krvi pakirane s rashladnim elemenatima i bez njih, kao i utjecaj vanjske temperature na kvalitetu uzorka. U venskim uzorcima 38 darivatelja krvi tijekom zime i njih 36 tijekom ljeta određeni su stupanj hemolize i kompletna krvna slika. Jedan uzorak po ispitaniku ostavljen je u kontroliranim uvjetima na +4 °C. Dva seta uzoraka poslana su zrakoplovom iz Zagreba u Bruxelles, jedan s rashladnim elemenatima i jedan bez njih, a druga dva seta poslana su u London po istom načelu. Pakovanja s rashladnim elementima čuvana su u kontroliranim skladišnim uvjetima u zračnim lukama (+2 °C do +8 °C), dok su pakovanja bez rashladnih elemenata čuvana u ambijentnim skladišnim uvjetima. Uređaji za kontinuirano mjerenje temperature korišteni su za nadzor temperature tijekom transporta. Naše istraživanje otkrilo je statistički značajne razlike u nekoliko hematoloških parametara kada se uspoređuju uzorci pohranjeni u kontroliranim laboratorijskim uvjetima i oni koji se transportiraju zračnim prijevozom. Te su razlike bile izraženije u uzorcima transportiranim tijekom ljeta. Uvjeti transporta bez rashladnih elemenata imali su dodatni negativni utjecaj na kvalitetu uzoraka. Transport uzoraka pomoću rashladnih elemenata i kontrolirani uvjeti skladištenja u zračnim lukama ponekad nisu dovoljni za održavanje laboratorijskih uvjeta skladištenja

Communication Architecture in Urban Traffic System

Glavna tema ovog rada jest komunikacijska arhitektura u gradskom prometnom sustavu. Opisuje se definicija ITS arhitekture, njene podjele i pravila koja definiraju njen razvoj kroz metodološki pristup. Nakon što se osnovna podjela izvrši, primarni fokus ostaje na komunikacijskog arhitekturi. U radu su opisani funkcionalni elementi komunikacijske arhitekture odnosno njene komponente, kao i referentna arhitektura stanice ITS-a. U daljnjem slijedu predstavljaju se neki kooperacijski ITS sustavi u gradskom prometnom sustavu. Predstavljeni su neki projekti čija zadaća uključuje razvoj kooperativnih sustava, neki od njih su CVIS i Safespot projekti, kao i VRUITS projekt koji je poslužio za primjer idealnog gradskog prometnog sustava iz komunikacijskog aspekta.The main theme of this final paper is communication architecture in urban traffic system. It describes the definition of ITS architecture, its breakdown and the rules that define its development through the methodology approach. After the primary breakdown is set, the primary focus stays on communication architecture. In this final paper the functional elements of the communication architecture are described, as well as the reference architecture of the ITS station. Furthermore, some cooperation ITS (C-ITS) systems are introduced concerning urban traffic systems. Those systems are introduced in a manner of projects whose purpose is development of the C-ITS systems, some of the mentioned ones include CVIS and Safespot projects, as well as VRUITS which served as an example of the ideal urban traffic system from the communication viewpoint

Validation d'une méthode de mesure de l'enfoncement d'un implant fémoral cimenté de type Exeter.

Total hip arthroplasty has become one of the most common procedures in orthopedic surgery. These patients must nevertheless be followed with care due to the risk of instability. Knowledge of early migration behavior can provide an indirect assessment of implant fixation. The purpose of this work was to develop a new measurement tool for early assessment of the femoral component.English AbstractJournal ArticleValidation StudiesSCOPUS: ar.jinfo:eu-repo/semantics/publishe

DISTRIBUTED 3D INFORMATION VISUALIZATION Towards Integration of the dynamic 3D graphics and Web Services

Abstract: This paper focuses on visualization and manipulation of graphical content in distributed network environments. The developed graphical middleware and 3D desktop prototypes were specialized for situational awareness. This research was done in the LArge Scale COllaborative decision support Technology (LASCOT) project, which explored and combined software technologies to support humancentred decision support system for crisis management (earthquake, tsunami, flooding, airplane or oil-tanker incidents, chemical, radio-active or other pollutants spreading, etc.). The performed state-of-the-art review did not identify any publicly available large scale distributed application of this kind. Existing proprietary solutions rely on the conventional technologies and 2D representations. Our challenge was to apply the "latest " available technologies, such Java3D, X3D and SOAP, compatible with average computer graphics hardware. The selected technologies are integrated and we demonstrate: the flow of data, which originates from heterogeneous data sources; interoperability across different operating systems and 3D visual representations to enhance the end-users interactions.
