    One of the first order problems which interest through its importance the whole billowy surface of the country is the preventing and fighting against soil erosion. Although there were made antierozional works on significant surfaces, their rhythm is inferior the development rhythm of the soil erosion and even these works didn’t always reach their aim. The experiments made revealed the decidedly part of the vegetal cover in fighting against soil erosion , part amplified also by the high productions of fodder gained in the case of using the biological material on different slope lands. The antierozional measures with biological character must have at their origin a study and detailed researches of the vegetation, for establishing the species and the herb mixtures corresponding to the conditions from the respective region

    A MEASUREMENT OF RURAL TOURISM DESTINATIONS’ COMPETITIVENESS

    The trend of rural tourism is growing and is becoming increasingly significant for most nations. Rural tourism is believed to have the potential to revive traditional approaches and perspectives on tourism and provide new dimensions to sustainable growth. Romania is regarded as one of the main destinations with a high potential in sustainable tourism development, due to its beautiful, unspoiled rural landscapes, traditions, and rustic lifestyle. Tourism, as a development tool, in rural communities, is one of the major concerns. The scarcity of case studies on rural tourist competitiveness, particularly in Romania, is what inspired the current research. This study attempts to investigate the factors that impact Romania’s rural tourism’s competitiveness and develop a conceptual framework for measuring it. In conducting our research, there were employed both exploratory and descriptive approaches. Secondary data from statistical and published research and studies were gathered, and it were collected primary data through surveys and personal interviews. The objective of the current research was to introduce a distinct and exclusive method of evaluating tourism in rather small regions with unique characteristics and applied and test the proposed model to Maramures region. The paper concludes that measuring and understanding rural tourism competitiveness and dynamics is essential for supporting sustainable development in rural areas, and it is of great importance for practitioners, policy makers and researchers

    THE EFFECT OF TiO2 NANOPARTICLES (DOPED OR NOT WITH Ag, ENCAPSULATED OR NOT IN LYPOSOMES), ON THE SPLEEN ULTRASTRUCTURE IN Mus musculus SPECIES, EXPOSED AT A STRESS FACTOR X-RAYS

    The present experiment was performed on young females of Mus musculus, 22-24 g each, intraperitoneal injected with a suspension of titanium dioxide (five injections of 0.5 ml each, one at two days, with 0.01% TiO2 or TiO2-Ag suspension). The TiO2 nanoparticles of anatase crystallization form, 10-20 nm size, wereconjugated or not with 1% Ag, encapsulated or not in lyposome. A day after the third injection, half of theanimals received a sublethal dose of X-rays (2.58 Gy; the stress factor). A day after the last injection, the animals were sacrificed through the section of thecarotid artery. Ultrastructural investigations were performed at the spleen level. The analysis of the ultrastructural features from the spleen level enabledthe following observations: the single action of the TiO2 or TiO2-Ag nanoparticles induced an inflammatory process, but in the presence of X-rays, they manifested a slight protective effect; the TiO2-Ag nanoparticles, encapsulated in liposome, manifested a strong radioprotective effect, but the endocapsulation process is not optimal and has to be improved; the presence of a protective effect at the spleen level can suggest that the TiO2-Ag nanoparticles can be used to enhance the organism resistance in case of carcinogenic treatment (in animal or in homo)

    Antibody protection against long-term memory loss induced by monomeric c-reactive protein in a mouse model of dementia

    Monomeric C-reactive protein (mCRP), the activated isoform of CRP, induces tissue damage in a range of inflammatory pathologies. Its detection in infarcted human brain tissue and its experimentally proven ability to promote dementia with Alzheimer’s disease (AD) traits at 4 weeks after intrahippocampal injection in mice have suggested that it may contribute to the development of AD after cerebrovascular injury. Here, we showed that a single hippocampal administration of mCRP in mice induced memory loss, lasting at least 6 months, along with neurodegenerative changes detected by increased levels of hyperphosphorylated tau protein and a decrease of the neuroplasticity marker Egr1. Furthermore, co-treatment with the monoclonal antibody 8C10 specific for mCRP showed that long-term memory loss and tau pathology were entirely avoided by early blockade of mCRP. Notably, 8C10 mitigated Egr1 decrease in the mouse hippocampus. 8C10 also protected against mCRP-induced inflammatory pathways in a microglial cell line, as shown by the prevention of increased generation of nitric oxide. Additional in vivo and in vitro neuroprotective testing with the anti-inflammatory agent TPPU, an inhibitor of the soluble epoxide hydrolase enzyme, confirmed the predominant involvement of neuroinflammatory processes in the dementia induced by mCRP. Therefore, locally deposited mCRP in the infarcted brain may be a novel biomarker for AD prognosis, and its antibody blockade opens up therapeutic opportunities for reducing post-stroke AD risk

    NEDA—NEutron Detector Array

    Get PDF
    The NEutron Detector Array, NEDA, will form the next generation neutron detection system that has been designed to be operated in conjunction with Îł-ray arrays, such as the tracking-array AGATA, to aid nuclear spectroscopy studies. NEDA has been designed to be a versatile device, with high-detection efficiency, excellent neutron-Îł discrimination, and high rate capabilities. It will be employed in physics campaigns in order to maximise the scientific output, making use of the different stable and radioactive ion beams available in Europe. The first implementation of the neutron detector array NEDA with AGATA 1Ď€ was realised at GANIL. This manuscript reviews the various aspects of NEDA

    Relationship between molecular pathogen detection and clinical disease in febrile children across Europe:a multicentre, prospective observational study

    Background: The PERFORM study aimed to understand causes of febrile childhood illness by comparing molecular pathogen detection with current clinical practice. Methods: Febrile children and controls were recruited on presentation to hospital in 9 European countries 2016–2020. Each child was assigned a standardized diagnostic category based on retrospective review of local clinical and microbiological data. Subsequently, centralised molecular tests (CMTs) for 19 respiratory and 27 blood pathogens were performed. Findings: Of 4611 febrile children, 643 (14%) were classified as definite bacterial infection (DB), 491 (11%) as definite viral infection (DV), and 3477 (75%) had uncertain aetiology. 1061 controls without infection were recruited. CMTs detected blood bacteria more frequently in DB than DV cases for N. meningitidis (OR: 3.37, 95% CI: 1.92–5.99), S. pneumoniae (OR: 3.89, 95% CI: 2.07–7.59), Group A streptococcus (OR 2.73, 95% CI 1.13–6.09) and E. coli (OR 2.7, 95% CI 1.02–6.71). Respiratory viruses were more common in febrile children than controls, but only influenza A (OR 0.24, 95% CI 0.11–0.46), influenza B (OR 0.12, 95% CI 0.02–0.37) and RSV (OR 0.16, 95% CI: 0.06–0.36) were less common in DB than DV cases. Of 16 blood viruses, enterovirus (OR 0.43, 95% CI 0.23–0.72) and EBV (OR 0.71, 95% CI 0.56–0.90) were detected less often in DB than DV cases. Combined local diagnostics and CMTs respectively detected blood viruses and respiratory viruses in 360 (56%) and 161 (25%) of DB cases, and virus detection ruled-out bacterial infection poorly, with predictive values of 0.64 and 0.68 respectively. Interpretation: Most febrile children cannot be conclusively defined as having bacterial or viral infection when molecular tests supplement conventional approaches. Viruses are detected in most patients with bacterial infections, and the clinical value of individual pathogen detection in determining treatment is low. New approaches are needed to help determine which febrile children require antibiotics. Funding: EU Horizon 2020 grant 668303.</p
