The Effects of Economic Crisis on Country Risk

It is widely accepted that risk is a constant of the human activity in general. From this perspective, the expansion of business across country borders requires identification, assessment and brief analysis of the overall risk that operators would face in a targeted national economy.Country risk is the one that shows in a general manner the international business risks, reflecting the overall situation and the cumulative effects of other risks. It is therefore considered to be a diagnosis of the socio-economic potential of the country receiving international economic flows. The complex, dynamic and variable character of the "new economy" has imposed a permanent adaptation of the country risk concept and has increased its importance given the international affairs. This is because knowing and understanding it, enable the economic agents to make rational decisions, minimizing the risks and increasing the profitability of their foreign activities. Also for a greater efficiency in decision making regarding internationalization, a specific activity became essential, which is country risk management. Country risk issues remain open to interpretations, especially in the context of economic crisis. The situation the world economy is facing today, changes considerably the criteria and also the assessments regarding the cataloguing of country risk.risk, uncertainty, country risk, systematic risk, economic decline, risk management

Current data regarding homeostasis of tissues oxygenation in pathophysiological and therapeutic circumstances

Oxygen is essential for cellular respiration and energy production. Tissue oxygenation refers to delivering oxygen to cells throughout the body. Microcirculation brings blood through small sanguine vessels to maintain the cells' supply of nutrients and oxygen. Optimal tissue oxygenation and microcirculation are essential for maintaining healthy tissue. Conversely, poor oxygenation can cause tissue damage, impair wound healing, and increase infection risk. Several factors can affect tissue oxygenation and microcirculation, including age, lifestyle factors (such as smoking and stress), and underlying medical conditions (such as diabetes and high blood pressure). To improve tissue oxygenation and microcirculation, individuals can engage in healthy lifestyle habits such as regular exercise, healthy eating, stress management, and avoiding smoking. Tissue oxygenation can also be looked therapeutic, given that topical and cosmetic treatments such as massage, pelotherapy, hydrotherapy, moisturizers, and certain skin care products can help pro-mote healthy microcirculation at the somatic level. In the scientific literature, the focus is on hypoxia rather than tissue oxygenation. This article proposes a paradigm shift and emphasizes the homeostatic importance of microcirculation and tissue oxygenation in pathophysiological and therapeutic circumstances. The systematic review of the data from the last 2 years (2021-2022) and the meta-analysis performed on tissue oxygenation will contribute to the practical approach to the pathology circumscribed to tissue oxygenation

kaonic atoms experiment at the daφne collider by siddharta siddharta 2

The excellent quality kaon beam provided by the DA\PhiΦNE collider of LNF-INFN (Italy) together with SIDDHARTA/SIDDHARTA-2 new experimental techniques, as very precise and fast-response X-ray detectors, allow to perform unprecedented measurements on light kaonic atoms crucial for a deeper understanding of the low-energy quantum chromodynamics (QCD) in the strangeness sector. In this paper an overview of the main results obtained by the SIDDHARTA collaboration, as well as the future plans related to the SIDDHARTA-2 experiment, are discussed

Synthesis of ZnO/Au Nanocomposite for Antibacterial Applications

Annually, antimicrobial-resistant infections-related mortality worldwide accelerates due to the increased use of antibiotics during the coronavirus pandemic and the antimicrobial resistance, which grows exponentially, and disproportionately to the current rate of development of new antibiotics. Nanoparticles can be an alternative to the current therapeutic approach against multi-drug resistance microorganisms caused infections. The motivation behind this work was to find a superior antibacterial nanomaterial, which can be efficient, biocompatible, and stable in time. This study evaluated the antibacterial activity of ZnO-based nanomaterials with different morphologies, synthesized through the solvothermal method and further modified with Au nanoparticles through wet chemical reduction. The structure, crystallinity, and morphology of ZnO and ZnO/Au nanomaterials have been investigated with XRD, SEM, TEM, DLS, and FTIR spectroscopy. The antibacterial effect of unmodified ZnO and ZnO/Au nanomaterials against Escherichia coli and Staphylococcus aureus was investigated through disc diffusion and tetrazolium/formazan (TTC) assays. The results showed that the proposed nanomaterials exhibited significant antibacterial effects on the Gram-positive and Gram-negative bacteria. Furthermore, ZnO nanorods with diameters smaller than 50 nm showed better antibacterial activity than ZnO nanorods with larger dimensions. The antibacterial efficiency against Escherichia coli and Staphylococcus aureus improved considerably by adding 0.2% (w/w) Au to ZnO nanorods. The results indicated the new materials’ potential for antibacterial applications

Labor Outsourcing in the Globalization Process

Currently, the sense of responsibility opposite to their own professional development is more important than ever due to potential relocation of many economic activities worldwide, leading to the assessment of each job in terms that create value and unique skills that you can stake. There are no "American" or "European" jobs in the globalized world, but there are jobs that will inevitably revert to the most able, intelligent, effective and cheap, regardless of where they come from or where they live. Experience proved that outsourcing labor is not only cheaper but more effective. On this basis, Friedman built the inequation CQ + PQ> IQ, which expresses an absolute truth that whenever a very curious and passionate individual would be preferred to one with endowed with intelligence. So for us to fold to this flat world, education, training and continuous transformation have an important role.outsourcing, jobs, global chain

Point-of-Care Testing—The Key in the Battle against SARS-CoV-2 Pandemic

The deleterious effects of the coronavirus disease 2019 (COVID-19) pandemic urged the development of diagnostic tools to manage the spread of disease. Currently, the “gold standard” involves the use of quantitative real-time polymerase chain reaction (qRT-PCR) for SARS-CoV-2 detection. Even though it is sensitive, specific and applicable for large batches of samples, qRT-PCR is labour-intensive, time-consuming, requires trained personnel and is not available in remote settings. This review summarizes and compares the available strategies for COVID-19: serological testing, Point-of-Care Testing, nanotechnology-based approaches and biosensors. Last but not least, we address the advantages and limitations of these methods as well as perspectives in COVID-19 diagnostics. The effort is constantly focused on understanding the quickly changing landscape of available diagnostic testing of COVID-19 at the clinical levels and introducing reliable and rapid screening point of care testing. The last approach is key to aid the clinical decision-making process for infection control, enhancing an appropriate treatment strategy and prompt isolation of asymptomatic/mild cases. As a viable alternative, Point-of-Care Testing (POCT) is typically low-cost and user-friendly, hence harbouring tremendous potential for rapid COVID-19 diagnosis
