ENTREPRENEURIAL SUCCESS – BETWEEN EXPERIENCE AND OPPORTUNITY

Often, the issue of entrepreneurship is analyzed more in terms of the skills of the person in question and less in terms of secondary factors. However, one cannot neglect the role of luck in achieving success, nor the capitalization of the right opportunity at the right time. Although long-term success is clear that it cannot be ensured in the absence of financial, human, material or informational resources, time plays an essential role in consolidating an idea, as well as in ensuring a sustainable character, but it also becomes important. conjuncture. This paper addresses the issue of entrepreneurial success from two points of view, on the one hand through the prism of theory, on the other hand through a case study that can only be the stage for launching a more detailed research

Delayed Scattering of Solitary Waves from Interfaces in a Granular Container

In granular media, the characterization of the behavior of solitary waves around interfaces is of importance in order to look for more applications of these systems. We study the behavior of solitary waves at both interfaces of a symmetric granular container, a class of systems that has received recent attention because it posses the feature of energy trapping. Hertzian contact is assumed. We have found that the scattering process is elastic at one interface, while at the other interface it is observed that the transmitted solitary wave has stopped its movement during a time that gets longer when the ratio between masses at the interfaces increases. The origin of this effect can be traced back to the phenomenon of gaps opening, recently observed experimentally.Comment: To appear in Physical Review E, vol 7

CAPITALIZING THE TOURIST POTENTIAL IN CARAŞ-SEVERIN COUNTY AS A PREMISE FOR REGIONAL ENTREPRENEURIAL DEVELOPMENT

In the context when tourism has become a widespread phenomenon, there are many global concerns in this regard, with reference to the plans to protect the world’s cultural and natural assets, and to stimulate the sustainable development of this sector. Touristic, cultural and scientific bodies develop comprehensive strategies, initiating Conventions, drawing up plans and periodically preparing reports. Romania has a large number of tourist attractions, ranking 46th in the top based on this criterion, distinguishing itself also grace to the attractiveness of natural objectives, the total number of protected areas, the number of cultural objectives and the number of objectives in terms of oral and intangible heritage. Taking into account all these indicators, Romania may be proud of a vast touristic potential, which offers wonderful premises for starting a business in tourism, for the expansion of entrepreneurship and for the development of natural, cultural and anthropic resources. Each region and area of Romania has diverse and special particularities and characteristics, and we have to underscore their ability to become true business poles grace to the high level of their attractiveness, being capably of developing actual hospitality industries. The recognition of their existence and value obviously contributes to a very large extent to the promotion and inclusion of cultural objectives into various global rankings, actions that lead to an increased interest among tourists, and implicitly contribute to attracting a large number of visitors and generally have a significant media impact. In this respect, this paper highlights international and domestic coordinates related to the sizing and capitalization of tourism potential, analysing theoretical coordinates and statistical data. In addition, we also forward the results of a survey carried out in order to identify the prospects for capitalizing on the Romanian tourist heritage and the manner in which the highlighting of the Romanian touristic and cultural objectives can be a starting point for generating prosperous future business and can develop the business milieu in all areas, including in the regions experiencing a steep decline, like Caraş-Severin county.

Investigation of WO{sub 3}-Based H{sub 2}S Sensor Materials for Coal Gasification Systems

The aim of this project was to engineer the materials studied to enhance the so-called 3S criteria: Sensitivity, Selectivity, and Stability, by using the advantage of controlling structure and properties at nanometer dimensions. It targeted sensor materials that are able to detect poisonous gases resulting from coal-gasification processes, especially sulfur containing emissions. Research findings based on this award demonstrate that doping tungsten oxide (WO{sub 3}) with a small amount of Ti (e.g. 5% in our work) results in a new material that has a higher structural symmetry (e.g. tetragonal morphology) as well as narrower crystalline particle size distribution. As high quality materials with excellent ordered structure and narrower particle-size distributions (which can also withstand high-temperature technological environments such as those encountered in furnaces and coal gasification systems without their structure being affected by phase transformations) are needed for developing new, more sensitive sensor materials, W-Ti-O thin films grown by RF sputtering are valuable candidates for such roles. It is well known that pure WO{sub 3} will change its structure at elevated temperatures. Our work indicates that, Ti doping not only increases the stability of the resultant material by promoting structural phase modifications, but also increases its sensitivity by increasing the effective surface area exposed to the poisonous gas (fine microstructure and uniform distribution were observed)

The present paper tries to highlight the situation of supermarket staff in the city of Resita. Thus, the first part of the paper presents a theoretical background and a review of literature in the field, while the second part consists in a study carried out with the purpose of researching the attitude of customers on the behaviour of the sales staff

Integration of Blockchain Technology into Supply Network for Resilient and Efficient Acquisition [video]

In the modern acquisition, it is unrealistic to consider single entities as producing and delivering a product independently. Acquisitions usually take place through supply networks. Resiliency, efficiency, and effectiveness of supply networks directly contribute to the acquisition system\u27s resiliency, efficiency, and effectiveness. All the involved firms form a part of a supply network essential to producing the product or service. The decision-makers have to look for new methodologies for supply chain management. Blockchain technology introduces new methods of decentralization and delegation of services, which can transform supply chains and result in a more resilient, efficient, and effective supply chain. This research aims to review and analyze the selected current blockchain technology adoptions to enhance the resiliency of supply network management by facilitating collaboration and communication among suppliers and support the decision-making process. In the first part of this study, we discuss the limitations and challenges of the supply chain system that can be addressed by integrating blockchain technology. In the final part, we analyze multiple blockchain-based supply chain use cases to identify how the main features of blockchain are suited best for supply network management

Reduced Graphene Oxide on Nickel Foam for Supercapacitor Electrodes

The focus of this paper is the investigation of reduced graphene oxide (GO)/nickel foam (RGON) samples for use as supercapacitor electrodes. Nickel foam samples were soaked in a GO suspension and dried before being subjected to two different methods to remove oxygen. Atmospheric pressure annealed (APA) samples were treated with a varying number (10–18) of nitrogen plasma jet scans, where sample temperatures did not exceed 280 °C. Furnace annealed (FA) samples were processed in an atmosphere of hydrogen and argon, at temperatures ranging from 600 °C to 900 °C. Environmental Scanning Electron Microscope (ESEM) data indicated that the carbon to oxygen (C:O) ratio for APA samples was minimized at an intermediate number of plasma scans. Fourier Transform Infrared Spectroscopic (FTIR) and Raman spectroscopic data supported this finding. ESEM analysis from FA samples showed that with increasing temperatures of annealing, GO is transformed to reduced graphene oxide (RGO), with C:O ratios exceeding 35:1. X-ray Photoelectron Spectroscopy (XPS) and X-ray diffraction (XRD) data indicated the formation of RGO with an increasing annealing temperature until 800 °C, when oxygen reincorporation in the surface atomic layers becomes an issue. Supercapacitors, constructed using the FA samples, demonstrated performances that correlated with surface atomic layer optimization of the C:O ratio

Optical constants, band gap, and infrared-active phonons of (LaAlO₃)_0.3(Sr₂AlTaO₆)_0.35 (LSAT) from spectroscopic ellipsometry

Using spectroscopic ellipsometry, the authors determined the optical constants (complex dielectric function) for (LaAlO₃)0.3(Sr₂AlTaO₆) 0.35 (LSAT) from 0.01 to 6.5 eV. Above 0.5 eV, the data were described with a sum of two Tauc-Lorentz oscillators and two poles. A direct gap of 5.8 ± 0.1 eV was found. An Urbach tail extends to even lower photon energies and makes the crystal opaque above 4.8 eV. Using Fourier-transform infrared ellipsometry, the lattice dynamics was studied. Nine pairs of transverse/longitudinal phonons were found and attributed to disorder in the La/Sr sublattice, ordering in the Al/Ta sublattice, and two- phonon absorptio

The incidente of Salmonella spp. in some poultry products

The goal of the proposed research was to determine the presence and variation of serotypes of Salmonella spp. in poultry meat and eggs which are commercialized in various units. In particular samples were taken from the commercial units placed in the Central Agricultural Market mun. Chisinau, were the poultry products are delivered from different districts of the country. Samples were taken from the refrigerated carcasses as well as current consumption eggs placed in the marketing network. The insemination of the lavages were made on cultural artificial medium as Salmonella Shigella Agar and Bismuth sulfite agar. The bacteriological investigations results have shown that about 12% of the samples from both exanimated poultry carcasses (including the samples of the depth of the muscle) as well as from eggs, demonstrated the presence of bacterial serotypes of Salmonella spp. The serotypes prevalence was S. infantis, S. enteritidis, S. typhimurium. The results confirmed the necessity for further multilateral and depth study of Salmonella spp. spreading in conjunction with the monitoring of public health sector
