Influence of Sustainable Fertilization on Yield and Quality Food of Mountain Grassland

The semi-natural grasslands in Romanian mountains are particularly important for the sustainable development of this region. Therefore, the objective of this paper was to evaluate the effects of mineral and manure fertilization upon the sward in order to recommend certain versions which have minor repercussions upon the plant diversity. In this study, we examined the influence of organic and mineral fertilizers on the production, biodiversity and quality of green fodder. The experiment was set up in mountain grassland of Festuca rubra L. and Agrostis capillaris L., during five years. In the experiment was evaluated the effects of management treatments on productivity, biodiversity and quality of the forage grass. The rate applications of fertilizers determine the number of species and the rate of production. The small quantities of organic and mineral nutrients (10 t·ha-1 manure and 30 kg·ha-1 nitrogen) can lead to larger yields while at the same time, improving biodiversity conservation and the quality of forage. Using a low input-based management system can be a solution that will lead to higher yields and contribute to biodiversity conservation and the good quality of the forage. In conclusion the use of a fertilizer management regime based on small quantities of organic and mineral nutrients can lead to larger yields while at the same time, improving biodiversity conservation and the quality of forage

Opinions Regarding State Resilience

Resilience is the phenomenon conferred by the possibility of individual or collective recovery, intervened after serious traumas. It requires the adoption of positive thinking, the mobilization of self and positive factors, to abandon the past and use a desire to overcome dramatic moments, restore the original standard of living and open the way to success in the future. In the current hybrid threats and confrontations, it makes it possible to overcome the hiatus imposed by the unfavorable state, instituted at the national level. The state is the key that ensures the vision of recovery, accumulates the social will, makes individual manifestations of success possible! The political factor, administrative structures and collectivities will stimulate positive wills, support the creative energies of exponents, directing them towards successful manifestations. Specifically, the ternary elements-state/government authorities/society will be supported, taking into account exactly the hybrid effort, channeled towards their successive destabilization

Sustainable Management of Nardus stricta L. Grasslands in Romania’s Carpathians

The grassland area of Romania covers over 4.8 million hectares, of which more than a half are located in upland areas. In the present research it has been studied the influence of organic fertilization on the productivity, vegetal canopy and fodder quality of the intramontane Depression of Vatra Dornei, from the North-Eastern Romanian Carpathians, at rates of 20-50 Mg ha-1, applied either on a yearly basis, or every two years. The purpose of this study is to underline the dynamics of productivity and phytocenosis biodiversity, due to the application of some practical, technical measures meant to improve the production and fodder quality of Nardus stricta L. permanent grasslands, with minimal effects on the environment. The organic fertilizer rates triggered changes in the canopy structure by reducing the percentage of Nardus stricta L species, from 70% to 14-31%, and increasing the percentage of legumes, as well as the productivity and fodder quality 5-30%, respectively

Consensus standards for acquisition, measurement, and reporting of intravascular optical coherence tomography studies

Objectives: The purpose of this document is to make the output of the International Working Group for Intravascular Optical Coherence Tomography (IWG-IVOCT) Standardization and Validation available to medical and scientific communities, through a peer-reviewed publication, in the interest of improving the diagnosis and treatment of patients with atherosclerosis, including coronary artery disease. Background: Intravascular optical coherence tomography (IVOCT) is a catheter-based modality that acquires images at a resolution of ∼10 μm, enabling visualization of blood vessel wall microstructure in vivo at an unprecedented level of detail. IVOCT devices are now commercially available worldwide, there is an active user base, and the interest in using this technology is growing. Incorporation of IVOCT in research and daily clinical practice can be facilitated by the development of uniform terminology and consensus-based standards on use of the technology, interpretation of the images, and reporting of IVOCT results. Methods: The IWG-IVOCT, comprising more than 260 academic and industry members from Asia, Europe, and the United States, formed in 2008 and convened on the topic of IVOCT standardization through a series of 9 national and international meetings. Results: Knowledge and recommendations from this group on key areas within the IVOCT field were assembled to generate this consensus document, authored by the Writing Committee, composed of academicians who have participated in meetings and/or writing of the text. Conclusions: This document may be broadly used as a standard reference regarding the current state of the IVOCT imaging modality, intended for researchers and clinicians who use IVOCT and analyze IVOCT data

EXPERIMENTAL MODEL OF ACUTE GLAUCOMA ON RABBIT. HISTOLOGYCAL STUDY

The study was conducted on an experimental model of acute glaucoma on rabbit and investigates the histologycal modifications determined by the sudden increase of the intraocular pressure at the level of the retina.The histologycal analise shows that under conditions of the experiment there are discrete alterations at the level of the retinal layers, without a general modification of the retinal arhitecture

Optical Coherence Tomography to Assess Proximal Side Optimization Technique in Crush Stenting

Aim: The aim of this study was to explore the potential intraprocedural benefits of the Proximal Side Optimization (PSO) technique by Optical Coherence Tomography (OCT). Methods: A case series of 10 consecutive true bifurcation lesions, with severe long pathology of long side branch (SB), were randomly assigned to be treated by standard DK Crush procedure (non-PSO group) as compared to DK Crush in PSO modification (PSO group). The data from OCT investigation before crushing of the SB Drug-Eluting Stent (DES), after crushing, after first kissing balloon inflation (KBI), and after final angiography were compared between the two groups (Public trials registry ISRCTN23355755). Results: All 10 cases were successfully treated by the assigned technique. The two groups were similar in terms of indications for the procedure, bifurcation angle, and stent dimensions. As compared to the non-PSO, the PSO group showed larger proximal SB stent areas (5.8 ± 1.8 vs. 4.5 ± 0.5 mm2; p = 0.02), the larger delta between distal and proximal stent areas before crush (1.5 ± 0.7 vs. 0.6 ± 0.5 mm2; p = 0.004), and the larger Space of Optimal Wiring (SOW) after Crush (5.3 ± 1.8 vs. 2.5 ± 1.1 mm2; p = 0.02). The gaps in scaffolding within the ostial segment of the Side Branch DES were found in two patients from the non-PSO group. Conclusion: The DK Crush in PSO modification results in larger SB DES and SOW areas with better apposition to the vessel wall. As result, the SB DES acquires a funnel shape, which reduces the risk of passage outside the SB stent struts during re-wiring, thus, allowing predictable and secure results

Influence of Fertilizers on the Biodiversity of Semi-natural Grassland in the Eastern Carpathians

This investigation examines the influence of fertilization with organic and mineral fertilizers on the biodiversity of grasslands containing Festuca rubra, Agrostis capillaris and Nardus stricta. Permanent meadows were studied in terms of production of food, and of biodiversity. The current strategy of using organic fertilizers has raised concerns about resource conservation and environmental protection. The increase in the number of species is due to the fertilizers that have been applied leading to changes in the soil fertility status. This change in soil fertility has allowed other mesotrophic and eutrophic species to become established in fertilized meadows. In Romania, meadows belonging to this category occupy an area of approximately 1,600,000 hectares and have relatively low production rates. The experiment was located at Pojorata, Suceava County (Romania), in two different natural grasslands that had different floristic compositions. Manure improved the growth of a number of species, especially in the "plants from other botanical families" category, because of the pool of seeds that it contains. Using a management system based on fertilization with small amounts of organic and mineral fertilizers can help preserve the biodiversity of these meadows. The results of this study, in an area considered representative for large parts of the mountainous areas of Romania, indicated that fertilization treatments were able to maintain a high species diversity. </p
