Authors: Tarnu Lucian Ioan 
Published: September 2015

Abstract
When Romania joined the European Union, it was imposed that the Romanian legislation in the field of the security and health at work be in line with the European one. The concept of health as it is defined by the International Body of Health, refers to a good physical, mental and social condition. The improvement of the activity of preventing the traffic accidents as work accidents must have as basis the correct and accurate evaluation of risks of getting injured. The goal of the activity of prevention and protection is to ensure the best working conditions, the prevention of accidents and occupational diseases and the adjustment to the scientific and technological progress. In the road transport sector, as in any other sector, it is very important to pay attention to working conditions to ensure a workforce motivated and well qualified. Some features make it a more difficult sector risk management than other sectors. However, if one takes into account how it works in practice this sector and the characteristics of drivers and how they work routinely, risks, dangers and threats can be managed efficiently and with great success.

Modeling The Frontal Collison In Vehicles And Determining The Degree Of Injury On The Driver
Authors: Oţăt Oana Victoria 
Published: September 2015

Abstract
The present research study aims at analysing the kinematic and the dynamic behaviour of the vehicle’s driver in a frontal collision. Hence, a subsequent objective of the research paper is to establish the degree of injury suffered by the driver. Therefore, in order to achieve the objectives set, first, we had to define the type of the dummy placed in the position of the driver, and then to design the three-element assembly, i.e. the chair-steering wheel-dashboard assembly. Based on this model, the following step focused on the positioning of the dummy, which has also integrated the defining of the contacts between the components of the dummy and the seat elements. Seeking to model such a behaviour that would highly accurately reflect the driver’s movements in a frontal collision, passive safety systems have also been defined and simulated, namely the seatbelt and the frontal airbag.

Authors: Virginia Iuga , Claudiu Kifor 
Published: September 2015

Abstract
Manufacturing sectors and companies all over the world are successfully implementing lean principles within their processes. Nowadays, lean has become an indispensable part of global players. Companies worldwide need to be aware of multiple factors which weigh heavily on the success or failure of lean implementation. This paper focuses on giving a brief and structured overview over the fundamental organizational factors which play a substantial role for the lean manufacturing (LM) implementation process. The study below focuses on internal factors which are indispensable for a successful LM implementation within organizations. It is imperative that these internal factors are known, recognized and taken into consideration during the whole LM implementation process. Ignoring their influence on the process's implementation may lead to endangering the expected results or to making the process more difficult which could result in much higher human resource consumption.

AbstractThe article presents the effect of the addition of polymer to mortars with CEMI and its influence on durability under conditions of sulfuric acid or nitric and sulphur bacteria or nitrogen (nitrification and denitrification). Both acids corresponds to the products of metabolism of bacteriaAcidithiobacillus thiooxidansandThiobacillus denitrificans,Paracoccus denitrificansby the literature is about 0.15 mmol/dm3. The changes in tightness materials studied by determining moisture mass and absorption. Corrosion processes were identified by examination in a scanning microscope equipped with an X-ray microanalyzer and a mercury porosimeter. The research results presented showed that the solution has a significantly weaker effect on the composite cement and cement-polymer compared with the action of bacteria. The action of both environments caused two opposing processes: unsealing the structure and deposition of corrosion products.

Published: September 2015

Abstract
Computed tomography and rapid prototyping techniques can be used to construct and fabricate large size bone models for orthopaedics. Rapid Prototyping technology enables the fabrication of a true-to-scale bone joint model based on 3D virtual models, generated by segmenting patients’ CT images. The model can be used to plan, to simulate, to assist prosthesis implantation for difficult cases of THR (Total Hip Replacements). The main restriction of implementing such models into medical practice is high cost of their production. Physical models of pelvic bones, were constructed on the basis of data collected during standard CT examinations. A method of development of a large-size model while fulfilling the requirement for reducing the price of model fabrication in the article was presented. The method can be used for fabrication the models with 3DP technique. This paper also discusses the issue of production costs when utilizing other RP techniques as well as their usefulness in practice.

Published: September 2015

Abstract
The measurement of the strength of bonds between biomaterials and cells is a major challenge in biotribology since it allows for the identification of different species in adhesion phenomena. Biomaterials, such as diamond-like carbon (DLC), titanium, and titanium nitride, seem to be good candidates for future blood-contact applications. These materials were deposited as thin films by the hybrid pulsed laser deposition (PLD) technique to examine the influence of such surfaces on cell behavior. The biomaterial examinations were performed in static conditions with red blood cells and then subjected to a dynamical test to observe the cell detachment kinetics. The tests revealed differences in behavior with respect to the applied coating material. The strongest cell-biomaterial interaction was observed for the carbon-based materials compared to the titanium and titanium nitride. Among many tests, a radial flow interaction analysis gives the opportunity to analyze cell adhesion to the applied material with the high accuracy. Analysis of concentrates helped to select materials for further dynamic tests on blood using an aortic flow simulator. In this case, the platelet adhesion to the surface and their degree of activation was analyzed. The quality of the selected coating was tested using a scratch test. The analyses of the microstructure were done using high resolution transmission electron microscopy. The phase composition and the residual stress were analyzed using X-ray diffraction methods.
Multibody rigid models and 3D FE models in numerical analysis of transport aircraft main landing gear
Authors: Krason W. , Malachowski J. 
Published: September 2015

Abstract
Dynamic analyses of a transport aircraft landing gear are conducted to determine the effort of such a complex system and provide capabilities to predict their behaviour under hazardous conditions. This kind of investigation with the use of numerical methods implementation is much easier and less expensive than stand tests. Various 3D models of the landing gear part are defined for the multistage static FE analysis. A complete system of the main landing gear was mapped as a deformable 3D numerical model for dynamic analysis with the use of LS-Dyna code. In this 3D deformable FE model, developed in a drop test simulation, the following matters were taken into consideration: contact problems between collaborating elements, the phenomena of energy absorption by a gas-liquid damper placed in the landing gear and the response of the landing gear during the touchdown of a flexible wheel with the ground. The results of numerical analyses for the selected drop tests and the results from the experiments carried out on a real landing gear were used for verification of FE models and a methodology of the landing gear dynamics analysis. The results obtained from the various simulations of the touchdown have proved the effectiveness of the 3D numerical model and how many problems can be solved in the course of only one numerical run, e.g. geometric and material nonlinearities, a question of contact between the mating components, investigation of the landing gear kinematics, investigation of the energy dissipation problem in the whole system and the stresses influence on the structure behaviour, which can appear in some elements due to overload.

Authors: Kozłowski M. , Choromański W. , Kowara J. 
Published: September 2015

Abstract
The paper presents the issue of modelling the system of the PRT vehicle – track. The PRT – Personal Rapid Transit concept is defined as an innovative transport system composed of small vehicles (3–5 persons) moving on the light infrastructure situated at a height of above 5 meters above the ground. This is a system that combines the features of individual and public transport. An important feature of this system is the implementation of the transport approach known as the ‘point to point’ rule that is to say between the initial and the final stop the vehicle does not stop at the intermediate stops. The vehicle has no driver. Routing choice and collision avoidance are performed through a complex computer system.

“I Am Different From Other Women In The World” The Experiences Of Saudi Arabian Women Studying Online In International Master Programmes
Authors: Szilagyi Annamaria 
Published: September 2015

Abstract
This paper presents findings from a qualitative study that investigated seven female Saudi Arabian students of the University of Liverpool’s online Masters programmes. Qualitative, first-person research methods and hermeneutic phenomenology were chosen for the analysis and interpretation of transcripts (Langeveld, 1983; van Manen, 1997; Creswell, 2007, Roth, 2012). The principles of cultural anthropology (Hall & du Gay, 1996; Hannerz, 1992; Lull, 2001; Coleman, 2010) were used to take a snapshot of the interviewees’ particular world to provide an overview of the Saudi Arabian culture where the role of women is at the centre of academic, political, religious and social debate These findings reflect the participants’ everyday lives, identities, values and beliefs, presented in a self-reflective, personal ‘life-world’ story of one single Saudi Arabian woman. The findings demonstrate that the primary motivators in choosing online international education to further study are existing limitations of travelling to a university campus and customary gender-segregated education in Saudi Arabia. As a contrast, international online education offers the opportunity to gain up-to-date research-based knowledge in their chosen profession, learn critical thinking and problem solving skills and communicate with male and female students from different cultures.

Authors: Bączek Katarzyna , Szymborska-Sandhu Izabela , Pawełczak Anna , Węglarz Zenon 
Published: September 2015

Summary
An efficient method for in vitro propagation of bastard balm by enhanced axillary shoot branching has been developed. The material to establish in vitro culture was shoot tips collected from three-year-old plants in May. The shoots obtained from initial explants were placed on MS/B5 medium containing 0.1, 0.5 or 1.0 mg/l BA with 0.01 mg/l NAA or without the auxin. The highest number of shoots per explant was obtained on the medium with 1.0 mg/l BA (3.9 shoots per explant). For the rooting of shoots ½ MS/B5 with IBA (0.25, 0.50 and 1.0 mg/l) medium was used. The medium without plant growth regulators served as a control. The best root regeneration was observed on the medium without IBA (87.1% of cuttings rooted). IBA used in the medium for shoot rooting affected the morphological traits of obtained microcuttings but not affected their weight. Irrespective of auxin concentration in this medium, obtained microcuttings acclimated in ex vitro conditions very well.

Published: September 2015

AbstractThe applicability of amino acid tricine has been investigated for the modification of solid wood. Oak, walnut, cherry, and birch wood lamella were impregnated with a tricine solution and subjected to a drying process. The interaction between tricine and wood components was analyzed by attenuated total reflectance-Fourier transform infrared and nuclear magnetic resonance spectroscopy, and the reactions only with hemicelluloses were detected. Xylosylamine structures were found among the reaction products of xylose and tricine, and solid oak wood also showed this type of reaction. The equilibrium moisture content of the modified wood decreased, and this finding was interpreted as an indication of a modification of the polysaccharides. The hardness and tensile strength of the tricine-modified lamellae increased significantly. The change of the physical properties is probably due to the low moisture content with increased hydrogen bonding between wood cell wall components. A crystalline layer of tricine on the cell walls was observed by means of electron microscopy.
