RECENT EVOLUTIONS ON ROMANIAN CAPITAL MARKET

As Romania became member of the EU, its financial markets are operating more and more like those of a developed capitalist country and the firms have to take into consideration all the advantages and to face all the challenges regarding the new financing sources such as: the public capital market, the private equity funds.capital market, private equity funds, integration,

Is the Insurance Market in Romania Prepared for the Impact with the European Union One? International Level Comparisons

International statistics regarding the main index registered on the insurance market and in the structure reveals the activity level of insurance on the profile markets and their absorption capacity. Taking into account these results and international comparisons, in Romania, in 2006, which represents the preparatory year for the impact with European insurance market, the consolidation process of insurance industry has been continued, by the capitalization growth of insurance companies, fusions, changes in the shareholding structure and portfolios transfer. At the same time, by the implementation of new legal stipulation, one can notice a growth of the preparation level and professional improvement of the employees from the insurance domain, with positive effects on performed services quality and on the information given to consumers of insurance products.insurance industry, insurance market, insurance penetration

CROWDFUNDING – FORMS, FACTS AND IMPLICATIONS

In the context of actual international economic and financial context, the firms, Small and Medium Enterprises (SMEs) especially the start-ups, still confront with accessing to finance problems. This fact determined a reorientation towards other alternative forms of financing. Thus, in recent years, an increasing range of financing options (crowdfunding, angels investors, venture capital) has become available to SMEs, although some of them are still at an early stage of development or, only accessible to a part of SMEs. As an alternative form of financing, the crowdfunding is often used by start-ups or developing businesses. Crowdfunding is an innovative way to identify new sources of funding for projects or business and to get useful market information, to access new customers using the power of online community. In less than a decade, crowdfunding extended in many developed countries from Europe and all over the world but also it is attracting an important interest in the developing countries. Despite these positive trends, there are still many barriers agains the new forms of alternative financing. Besides the new programs developed at the national and international level, should be undelined that a credible and relistic crowdfunding system require entrepreneurs and willing investors but also a number of key determinat factors (regulatory framework, ecosystem, technological solutions, etc) that enable all parties to participate and take benefits from this new financing alternative

Human vomeronasal epithelium development: An immunohistochemical overview

The vomeronasal organ (VNO) is the receptor structure of the vomeronasal system (VNS) in vertebrates. It is found bilaterally in the submucosa of the inferior part of the nasal septum. There are ongoing controversies regarding the functionality of this organ in humans. In this study we propose the immunohistochemical evaluation of changes in components of the human vomeronasal epithelium during foetal development. We used 45 foetuses of different age, which were included in three age groups. After VNO identification immunohistochemical reactions were performed using primary antibodies against the following: neuron specific enolase, calretinin, neurofilament, chromogranin, synaptophysin, cytokeratin 7, pan-cytokeratin and S100 protein. Digital slides were obtained and following colorimetric segmentation, surface area measurements were performed. The VNO was found in less than half of the studied specimens (42.2%). Neuron specific enolase and calretinin immunoexpression showed a decreasing trend with foetal age, while the other neural/neuroendocrine markers were negative in all specimens. Cytokeratin 7 expression increased with age, while Pan-Ctk had no significant variations. S100 protein immunoexpression also decreased around the VNO. The results of the present work uphold the theory of regression of the neuroepithelium that is present during initial stages of foetal development

EXPERIMENTALLY RESEARCHES ON CERTAIN TYPES OF SPRAYING DEVICES USED IN FRUIT PLANTATIONS

Reduce the loss of fluid and decrease environmental impact due to thephenomenon of drift, at the same time with a high biological efficiency of pulverization wasone of the major problems of the technology of spraying treatments. For this reason theywere designed and constructed spraying devices able to significantly reduce the loss ofliquid

STUDY ON THE STRUCTURE OF THE PARK OF TRACTORS AND AGRICULTURAL MACHINERY IN ROMANIA

This paper presents a study on the dynamics of the tractors and agricultural machinery based on data provided by the Ministry of Agriculture and Rural Development and the National Institute of Statistics. There are, also, presented issues regarding new and used agricultural machinery market, and solutions to the renewal of tractors and agricultural machinery

THE DESIGN AND REALIZATION OF A CONTROL SCHEME FOR A TRANSPORT SYSTEM WITH TRAILERS USED IN THE FOOD INDUSTRY

Given the diversity of products that need to be transported into the food processing industry, transporting with trailers on narrow rail can be used successfully in case of granular solid materials, or in the form of units (in cold or hot state), and also for the unit tasks.Transporting with trailers on the narrow track takes the advantage of a securityoperation, with minimum costs, higher travel speeds (6...8 km/h), as well as of a high reliability. Transport of materials also can be run over longer distances (compared with conveyors or roller) and on combined paths (rectilinear and curvilinear).Trail transport and can travel also on a system of single rail guides (the trail being designed with a central shaft), thus allowing installation of guides on the nearest wall and eliminating the necessary support systems in the production hall. Downloading the material of conveyance can be done through a funnel located at the bottom of trail transport (with the help of two valves operated by a hydraulic cylinder, or by means of a rotating system)

ILIOPSOAS IMPINGEMENT AFTER TOTAL HIP ARTHROPLASTY - FINITE ELEMENT ANALYSIS

Aim of this paper. Is to study the iliopsoas impingement with threedimensional modeling (3D) after total hip arthroplasty in extended position of the hip in case of 28 and 36 mm diameter prosthetic heads and the acetabular component in malposition (retroversion). Material and methods. We performed a 3D reconstruction of the pelvic bone, the left femur and left iliopsoas muscle of a 27 year old male based on CT images. After that we created a solid body that we used for the arthroplasty performed in the variants mentioned above and we used the finite element method for the analyses. Results. There were no traces of impingement with the 28 mm and 36 mm diameter femoral head, when the joint is in extension. When the acetabular component was in malposition, we found a stress aerie on the iliopsoas muscle and acetabular component meeting point. Conclusion. In our research, we demonstrated by 3D modeling and finite element analysis that after total hip arthroplasty using a large diameter femoral head, with the hip in extension, there is no pressure on the surface of iliopsoas muscle, contrary with the case of the acetabular component in retroversion. We can avoid this placing the acetabular component in angle of 45o inclination and 10o anteversion

IMPROVING QUALITY OF LIFE AFTER HIP REVISION ARTHROPLASTY

Nowadays the number of primary arthroplasties is growing and revision arthroplasty is becoming increasingly necessary. In this study we intend to examine the effectiveness of arthroplasties and assess the quality of life. We included 35 patients with revision arthroplasty and 35 primary hip arthroplasty patients who had surgery between 2011 and 2012 in the study. To examine the results we used the modified Harris hip score and the Rosser matrix, which was completed before surgery and 2-3 years after the procedure. We observed a statistically significant improvement: from 34 preoperative Harris hip score 75 at the 2 years postsurgery assessment and 72 at the 3 years postoperative assessment (p <0.0001). Significant improvements were also registered when assessing the health state with the Rosser matrix. The effect for the Harris score had a value of 2.06 which testifies the revision surgery has a high effectiveness. This means that with this kind of procedures dramatic improvement in quality of life can be achieved
