Dynamic Anthropometric Characteristics of Pedestrians in Case of Car Collision

The paper gives an overview of the specific features of anthropometric characteristics of humans – pedestrians in case of car accidents involving pedestrians and cars. Here, special attention has been paid to the configuration of the human body while moving, which is in turn related to the initial conditions of a collision. Special part of biomechanics in humans refers to their moving, where human’s walk has a specific posture as a mechanical phenomenon. Based on the carried out analysis the need has been observed for a classification of anthropologic variables by means of which the dynamic inertia moments of a walking human can be calculated, as well as the human, who hit by a car in a traffic accident flies along a production curvilinear path. With the development of ergonomics, and the accompanying increased application of anthropometry, the static anthropometry was abandoned, since the humans are considered highly variable in their dimensions, which is extremely importantfor the dynamic analysis of the human body posture in the collision process

Smjernice Hrvatskog društva za hematologiju i transfuzijsku medicinu u dijagnostičko-terapijskom postupku za trombocitopeniju izazvanu heparinom (HIT) [Croatian Society for Haematology and Transfusion Medicine Guidelines on the diagnosis and management of heparin induced thrombocytopenia (HIT)]

Heparin induced thrombocytopenia (HIT) is a serious complication of heparin administration. In the last decade, this clinical syndrome has come into the focus of interest, primarily because of the severe thromboembolic complications that may lead to lethal outcome. In addition, great improvements have been made in the treatment with direct thrombin inhibitors and in laboratory diagnosis of HIT. As guidelines for diagnostic and management of HIT upgrade the quality of patient treatment, activities for their development have been launched in the Republic of Croatia. Based on British Committee for Standards in Haematology (BCSH) recommendations on diagnostic and treatment of HIT from 2006, activities for the introduction of new assays for anti-heparin antibodies were launched in 2008 and 2009, including algorithm of laboratory testing for HIT, sheet for clinical assessment of HIT (4T score), and education oftransfusiologists and clinicians. Upon evaluation of the results collected during one-year period, the Croatian Society of Haematology and Transfusion Medicine nominated a task force for the development of guidelines for HIT in January 2010. Following wide-ranging discussion, the guidelines were adopted in May 2011

Preraspodjela cestovnog prostora u središnjoj zoni grada Zagreba

U radu je dan prijedlog preraspodjele cestovnog prostora u središnoj zoni grada Zagreba. Takvim svrhovitim oblikovanjem prometnih površina mogao bi se dobiti dodatni prostorod 31 979 m2 koji bi značio veću sigurnost, manje zagađenje okoliša, ali i vraćanje nemotoriziranim sudionicima prometa površina koje su im bile oduzete predimenzioniranjem automobilskog prometa

Evaluation of the Favourable Ecological Impact of the Railway on the Environment

The railway has advantages over other branches of longdistancetransportation from the ecological, economic, safety,and technological point of view.The paper gives an evaluation of the favourable influenceof railway traffic on the environment reflected in the rationalenergy consumption, significantly reduced need of physicalspace, and reduced air pollution.Having these data in mind, the railway is considered tohave a negligible influence on environmental pollution. However,studying even such small amounts plays a significant rolein the traffic safety and in the lives of people and nature itsel

Prometni "infarkt" u gradovima: pokušaji rješenja

This paper deals with an attempt at resolving the problem of gridlock in urban areas with particular reference to environment- friendly traffic system. In order to help creating an environment-friendly traffic system, it shall be necessary to take the following measures: gradual relocation of motor traffic by means of a correctly aspected traffic/urban planning policy, rerouting of motor traffic for purposes of improvement of the quality of non- Promet, vol. 6, 1994, br. 5, 127-131 -motorist traffic, improvement of the very method of operation of motor vehicles by technology/control measures and implementation of measures of traffic abatement in residential areas.</p

Funkcije ceste u izgrađenom području i mjere smirivanja prometa

This paper deals with a major function of the road in populated areas with particular reference to the measures taken on abatement of traffic flows. Considering the fact that major part of the area designed for traffic in populated areas has been used for purposes of road traffic to disadvantage of pedestrians and cyclists, it is necessary to initiate activities on purposes of structuring of the road area and this by measures of abatement of traffic flows with the basic objective of humanization of traffic i.e. harmonization of community life and traffic in the urban area. This paper deals with some examples of listed measures with low, r:cdiwn and high funding requirements.</p

Smanjenje štetnosti ispušnih plinova dizelskog motora

The paper deals with some possibilities of reduction of Diesel engine exhaust emission hazards. For purposes of purification of exhaust emissions, the in-built filters can be provided, like ceramic filters for sooth and water filters for gases. The oxidation catalyst may also be provided in addition to filters. Hybrid systems have been tested in "Golf' automobiles i.e. the combination of internal combustion engine and electric drive. This vehicle has been named "Eco Golf'. A mixture of Diesel fuel and n-butanol in the ratio of 60:40 has been used as the alternative fuel introducing the reduction of NOx by 8% and of particles by 36%. All limit values of Diesel engine exhaust gas components have been given in ECE R49 test.</p

Analysis of harmful emissions generated by road traffic in the city of Zagreb and proposals of measures

The total number of registered road motor vehicles in Croatia in 2008 was 2,021,936 out of which 20.5% were registered in the city of Zagreb. Due to improper engine operating conditions, relatively low speeds (below 80km/h), large number of vehicles, high percentage of defective vehicles, poor fuel quality, the highest effect on air pollution in the city of Zagreb is generated by road motor vehicles. If air pollution in the city is analyzed from 2001 to 2009, it may be concluded that the biggest problem lies in the pollution by nitrogen oxides, airborne particles and ground-level ozone, which means that taking these pollution parameters in consideration the air was of Category II, i.e. moderately polluted. The most endangered city areas are the industrial zones and traffic nodes. Numerous European cities have been undertaking activities in order to reduce air pollution, which include also the introduction of new standards for new vehicles, improvement of fuel quality, fuel and vehicle taxing, usage of alternative fuels, etc. The city of Zagreb is no exception and since the current traffic system has not been solved in an optimal manner and since there is a lot of room for improvements in technical, technological and ecological sense, this paper will analyze the impact of road traffic on air pollution and offer proposals of measures to establish a sustainable traffic system of the City of Zagreb. Some of the proposals for reducing the harmful emissions from road traffic in the city of Zagreb include: reconstruction of the road network (emphasis on intersections), introduction of the traffic-dependent control of light signalized intersections, usage of intelligent transport systems for guiding and better organization of traffic, “Park-and-ride” system, etc. The traffic system of the city of Zagreb can be optimized without the construction of new roads by introducing intelligent traffic control with possible organizational changes and introduction of an accompanying system for control and management, thus significantly contributing to the reduction of the pollutants. The best practice, e.g., of the implemented measures of the transport policy on the CIVITAS pattern of 36 European cities, however, clearly suggest development guidelines for urban transport and can be entirely implemented in modelling the development of urban public transport in Croatia
