THE CONCEPT OF SUSTAINABLE DEVELOPMENT THROUGH ECONOMIC GROWTH AND DIVERSIFICATION OF THE LABOUR MARKET IN THE INDUSTRIAL AREAS AFFECTED BY RESTRUCTURING

In the context of what is implemented through dualism "ecosystem-efficient", sustainable development involves the care of the human potential of the present situation and the future of its natural resources, energy, materials and information. As an effect of responsibility for future generations, the efficient use of resources requires, at the same time, the operation of a sustainable economy, by diversification and development of the labour market in order to meet present and future demands of human society. At local and regional level, through the closing of mines and large enterprises, with an effect in restructuring the economic sector and employment, development strategies and rehabilitation of the affected industrial areas as a common principle approach, analyzing the problems, defining the objectives and policies, identifying actions to attack problems and provide for mechanisms that will enable the progress control. In this paper it is presented the concept of sustainable development as imperative for economic growth, diversification and development of the labour market, being dealt the representative criteria and principles of sustainable development strategy of any company. Are defined the components and objectives of a strategy for local and regional development of industrial areas affected by the restructuring

Characterization Techniques Coupled With Mathematical Tools for Deepening Asphaltenes Structure

Asphaltenes are the heavy fraction of fossil fuels, whose characterization remains a very difficult and challenging issue due to the still-persisting uncertainties about their structure and/or composition and molecular weight. Asphaltene components are highly condensed aromatic molecules having some heteroatoms and aliphatic functionalities. Their molecular weights distribution spans in a wide range, from hundreds to millions of mass units, depending on the diagnostic used, which is mainly due to the occurrence of self-aggregation. In the present work, mass spectrometry along with size exclusion chromatography and X-ray diffraction analysis have been applied to asphaltenes for giving some further insights into their molecular weight distribution and structural characteristics. Relatively small polycyclic aromatic hydrocarbons (PAHs) with a significant degree of aliphaticity were individuated by applying fast Fourier transform (FFT) and double bond equivalent (DBE) number analysis to the mass spectra. X-ray diffraction (XRD) confirmed some aliphaticity, showing peaks specific of aliphatic functionalities. Size exclusion chromatography indicated higher molecular weight, probably due to the aliphatic substituents. Mass spectrometry at high laser power enabled observing a downward shift of molecular masses corresponding to the loss of about 10 carbon atoms, suggesting the occurrence of aryl-linked core structures assumed to feature asphaltenes along with island and archipelago structures

A STOCHASTIC MODELING FOR THE UNSTABLE FINANCIAL MARKETS

Considering the present economic context, the measurement of performances has become a permanent preoccupation for organizations, since the whole process is based on it, offering the necessary feedback to identify both the positive actions which have led to favorable results for the organization, and the negative ones, in order to correct them in the future. To do this, we have to measure what is most importantly to measure. Starting from these considerations, the present paper approaches from a theoretical and practical point of view the economic rate of return as the indicator which synthesizes best an organization’s financial-economic performance. We have calculated and analyzed the economic rate of return for a group of Ten Romanian Firms in the food industry, through different calculation relations, pointing out the advantages/disadvantages of each calculation method.belated integral, forward-backward stochastic equations, pathwise uniqueness, financial modeling.

Modern therapeutic options in diabetic foot ulcer

Diabetic foot is a severe complication of diabetes that occurs as a result of poor glycemic control, being associated with significant morbidity and mortality. Mortality associated with this disease is estimated at 5% in the first 12 months, and about 42% in the next 5 years. On average, it affects about 15% of people with diabetes during their lifetime, including as possible manifestations neuropathy, peripheral vascular disease, and subsequent ulceration which, if treated incorrectly, can lead to amputation. This paper presents a retrospective and descriptive study of patients diagnosed and treated for diabetic foot ulcers in the Proctoven Clinic. The study includes a group of 50 cases diagnosed with diabetic foot over a period of 5 years, from 01.01.2017 to 31.12.2021. In this study, the effectiveness of the modern treatment methods most frequently used in the surgical treatment of the diabetic foot is analyzed based on several parameters

THE OPPORTUNITY OF IMPLEMENTATION THE ANCHORED SUPPORTING OF UNDERGROUND EXCAVATIONS

As an objective necessity of restriction the scope of the steel timbering used for the current metalsupport of the underground excavations, resulting from the not correlation of the symmetric constructionsupporting system with uneven maximum vector manifestation of pressure, as well as economic considerations,generated by the high costs and labor for the lamination of metal profiles, by applying to the supplier aadditional treatments improve, it becomes increasingly necessary to introduce and generalization on how toconsolidate rocks by anchored support. The paper analyzes the possibility of generalization the anchoredsupport for underground excavations, as well as the specific features of this support system in its interactionwith the surrounding rock, with the aim of making the option for choosing this method of consolidation therocks

CREATING AN EXPERIMENTAL MODEL OF MINIMALLY INVASIVE SURGERY IN PIGS

Minimally invasive surgery is a common technique that replaces classic surgery because of many benfits, including reduced postoperative pain and shorter hospitalization time. Getting familiar with the skills needed to perform this techniques requires specific training. In this study, we developed a two-day training on four live pigs, where the participants had to identify the uro-genital tract, liver, gall bladder, stomach, intestines and performing certain maneuvers on them and we preferred to focus on the basic laparoscopy procedures, which can then be integrated into any procedure

Evidence for different episodes of aeolian construction and a new type of wind streak in the 2016 ExoMars landing ellipse in Meridiani Planum, Mars

We present evidence for a complex, multigenerational bed form pattern and a new type of wind streak (the ripple streak) in the landing site ellipse of the 2016 ExoMars Entry descent and landing Demonstrator Module (EDM) in Meridiani Planum (Mars). We identified three main groups of bright-toned bed forms. Population 3, represented by NE-SW trending bed forms located inside craters, was emplaced by winds coming from the NW or the SE. Population 2, emplaced by strong easterlies, formed by intracrater transverse aeolian ridges (TARs) and N-S trending megaripples (plains ripples). Population 1 consists of a relict bed form pattern emplaced by winds coming from the north or south. Alternatively, population 1 can represent a sand ribbon pattern that formed together with the plain ripples. We also report the presence of a new type of wind streak, the ripple streak, which is formed by the population 2 bed forms clustered in the wake zone of impact craters. Based on the results of this work, we now know the EDM module is set to land in a complex aeolian environment. Data from the Dust Characterization, Risk Assessment, and Environment Analyser on the Martian Surface onboard the EDM can help to better decipher the wind regime in Meridiani Planum

Thermal treatment under high-vacuum of tars relevant in combustion and material science

The composition of tars, typically derived from coal and heavy fuel processing or formed in fuel-rich combustion, determines their transformation into carbons relevant in combustion and environmental fields as well as for material production. The speciation of the huge number of aromatic components of tars, usually found in form of viscous black liquid or solid, is not straightforward because of the tar complexity and high molecular weight, spanning from few hundreds up to thousands of Da. To this regard, the pre-separation of tar in lighter and heavier fractions simplifies the further characterization of its composition. The present work reports a fractionation method of a typical sample of combustion-formed tar based on moderate heating in high-vacuum conditions (10-6 mbar). It was preliminarily tested on a single polycyclic aromatic hydrocarbon, coronene, and on synthetic mixtures of polycyclic aromatic hydrocarbons, presumed to be the basic aromatic moieties of tar components. Lighter components obtained by condensation/deposition as thin films and/or crystals, as well as the heavier residue, were analysed by optical microscopy and spectroscopy. The separation procedure allowed to get more information on the components distribution also inferring the self-organization in cluster assembly and/or crystal forms
