Construction and assembling optimization of power equipment

The main purpose of this paper is to elaborate a calculation program in Pascal language, using Delphi environment. This calculation program is designed to solve the power engineering optimization problems using the critical path method. For illustrating the use of the algorithm and the calculation program we propose an application from power engineering: a 400 kV electrical overhead line section realization. This paper is structured in 4 parts. In the first part of the paper we present the application as a problem of critic path. In the second part of the paper, we determine the critic path in a program graph and time reserves. In the third part of the paper we present a representative numerical application. In the fourth part of the paper it is described the calculation program

Optimal equipment programming for realizing an ensemble of electrical overhead lines

The main purpose of this paper is to elaborate a calculation program in Pascal language, using Delphi environment. This calculation program is designed to solve the power engineering optimization problems using the method of optimal Hamiltonian path and circuit, solved with the so called "Latin multiplication". For illustrating the use of the algorithm and the calculation program we present a problem of optimal equipment programming for realizing an ensemble of electrical overhead lines.This paper is structured in 4 parts. In the first part of the paper we present the application as a problem of optimal Hamiltonian path and circuit. In the second part of the paper, we determine the optimal Hamiltonian path (circuit) in a graph using the so called Latin multiplication method. In the third part of the paper we present a representative numerical application. In the fourth part of the paper it is described the calculation program

Influence of the noise generated by the electrical transformers upon the environment

Often, the electrical transforming stations are located in the proximity of inhabited areas.The electrical transformers from the stations generate noise that affects the residents of these areas.In this paper we will present the results obtained by identifying the sources of noise from the electrical transformers and their typical levels. We will also approach the methods of reducing the acoustic pollution which is generated as a result

The Ignored Peasants of Romanian Ethnology: Ovid Densusianu, Henri H. Stahl, and the Recalibration of Research on Rural Romania

The present study attempts to capture and explain a somewhat paradoxical theme: the way in which the national ethnology of the nineteenth century “ignored” the peasant world. Why did a science dedicated to the peasant world ignore the “voices” of peasants for a long period of time? Throughout the nineteenth century the ethnologist’s agenda did not overlap at all with that of the peasant in front of him: the urban researcher was interested in folk literature, music, dance, and dress, while the peasant wanted to talk about rural poverty and its causes. The ethnologist was engaged in building the national, while the peasant spoke about the social. Their discourses simply did not intersect. Changes did begin to happen at the beginning of the twentieth century: peasants began not only to be asked but were also listened to. Ovid Densusianu was responsible for this paradigm shift, redefining folklore during the first decade of the century. He was followed by the sociological monographic school, represented here by the work of Henri H. Stahl.</jats:p

Sustainable Growth Approaches: Quadruple Helix Approach for Turning Brașov into a Startup City

The aims of this study are to identify large companies&rsquo; role in stimulating local entrepreneurship, and higher education institutions&rsquo; contribution of fostering entrepreneurial activity in order to achieve an innovative ecosystem and turning Brasov into a startup city. To address the research questions, exploratory research was conducted among 18 representatives of companies and public institutions active in Brasov city, Romania. The findings confirm that large companies engage startups by collaborative models being also available to outsource a series of activities to entrust the startups with. These collaborations bring many opportunities to startups to scale up faster by using large companies&rsquo; resources and the routes to the markets on which they operate. Furthermore, this research reveals the need for a better synergy between education, research, and practice and, consequently, an improvement of the academic curriculum. It also exemplifies the need for joined theory and practice to influence policymakers in developing policies to create a sustainable entrepreneurial ecosystem. The empirical results have implications for both the entrepreneurship literature and entrepreneurship policies

INFLUENCE FACTORS FOR LEASING MARKET CONTRACTS

This paper aims to investigate the relationship between leasing contracts and some factors that influence the value of these contracts. In order to do this, we have decided on some quantitative marketing research by appealing to statistics for accomplishing the objectives that we have set: to find a correlation between the turnover percentage assigned to leasing expenses and several influence factors. This study indicated that the more contracts are signed by a firm, the more likely is to assign a bigger fraction of the income to each new leasing contract. The study confirmed that bigger companies are relying more on leasing as a way of financing than small companies. This study also discovered that companies with more employees are using larger contracts in order to sustain their activity. The findings are expected to contribute to adjusting the offers by the leasing companies, taking into consideration these factors and to using these factors in order to better predict the market evolution

A Pilot Colorectal Cancer Study Using Fecal Occult Blood Tests and Colonoscopy to Identify the Weaknesses of the Romanian Public Healthcare System before Implementing National Screening

The objective of this study is to investigate the feasibility of colorectal cancer (CRC) screening in the absence of a national screening program using the resources provided by the Romanian healthcare system. Study participants were recruited from adult patients (over 18 years old) registered with a general practitioner from an urban area over a period of 3 years (October 2019 to September 2022). Patients were recruited when they came for a consult at their family physician&rsquo;s office. The study excluded patients with a medical history of colorectal cancer. Written consent was obtained from the patients who agreed to participate. Patients who agreed to participate were recommended to undergo a fecal occult blood test (FOBT). For those with a positive FOBT result, a colonoscopy was recommended. The study identified a need and willingness of patients to participate in CRC screening when they were informed about it, especially when it involved a noninvasive test such as FOB. We did not anticipate the refusal to perform FOBT in the public healthcare system because the recommendation was made by a GP. We identified a deficit of specialists that can perform colonoscopies in the public healthcare system, insufficient health education, and a lack of dedicated pathways for screening

Innovation of Startups, the Key to Unlocking Post-Crisis Sustainable Growth in Romanian Entrepreneurial Ecosystem

This paper aims at identifying the entrepreneurial opportunities for establishing innovative startups during and post COVID-19 crisis. To reach this goal, we conducted an exploratory study based on semi-structured interviews with 168 students who intend to involve themselves in entrepreneurship in their future career. The research started from the debates in literature regarding the huge negative impact of the COVID-19 crisis on economic development, which can jeopardize the achievement of United Nations Sustainable Development Goals. The research findings confirm the results of other studies regarding the vulnerability of startups during crises, the reason why they have to refocus on innovative businesses, especially based on information and communication technology (ICT). Such businesses are considered incentives of sustainable development. Other ideas highlighted the importance of social entrepreneurship for the management of startups. It means that startups should develop strong relationships with employees but also with other stakeholders, like companies in the same industry, the public sector, academia, and citizens. In addition, changing the business culture aiming at developing green business could be an inexpensive solution for developing a sustainable entrepreneurial ecosystem. These empirical results have implications for both business and the academic environment, which should cooperate in order to overcome the crisis. Such an approach could be used in the long run in order to manage other crises and to develop sustainable business
