EDUCATIONAL MANAGEMENT- AS THE RESPONSE TO THE SOCIAL-ECONOMIC CRISIS IN CONTEMPORARY EUROPE

Taking carefully into consideration the way in which emerged and evolved the actual economic and financial crisis, in Europe and in Romania, one can conclude that the educational management, as an academic program, or as a scientific research, can provide some solutions. First are analyzed the initiatives taken by the decision factors from the superior European education, in 1999, before the breaking out of the crisis, through the Bologna Convention. Due to the educational management's particularity to establish a communication channel between academics, specialists in educational sciences, educational institutions managers and political leaders, are presented the beneficial effects which a number of decisions like the stimulation of young people's interest for the studying of economical and entrepreneurial sciences, systematic programs open socially and culturally of knowing the foreign languages, the analysis of career's dynamic in parallel to the modernization of the career education, could have.education, management, social-economic crisis

Efficient numerical algorithms for virtual design in nanoplasmonics

University of Minnesota Ph.D. dissertation. March 2017. Major: Mathematics. Advisor: Fadil Santosa. 1 computer file (PDF); vi, 96 pages.Nanomaterials have given rise to many devices, from high-density data storage to optical bio-sensors capable of detecting specific biochemicals. The design of new nanodevices relies increasingly on numerical simulations, driving a need for efficient numerical methods. In this work, integral equations are used to efficiently solve the electromagnetic transmission problem at the interface of a dielectric and a periodic metal nanostructure. Derivative-free trust-region methods are then used to optimize the geometry of the nanostructure

Cardiac Involvement in Trichinellosis: A Case of Left Ventricular Thrombosis

We report the case of a 42-year-old woman who was admitted to the hospital for fever, chills, nausea, vomiting, fatigue, myalgia, and general muscle weakness. All these symptoms had occurred 3 weeks after the ingestion of inadequately cooked pork meat, subsequently confirmed to be infested with Trichinella spiralis . Laboratory results showed mild leukocytosis, inflammation, and mild liver and muscle cytolytic syndrome, all suggestive of trichinellosis. Echocardiography showed apical hypokinesis and an apical mass (likely a thrombus). The immunologic assessment for the presence of Trichinella antigens was positive. The outcome was favorable after treatment with an anticoagulant, an antiaggregant, prednisone, and mebendazole. Follow-up controls showed the absence of any symptoms and thrombus, with only mild electrocardiogram modifications still present

Laboratory Techniques In Lingual Orthodontics

If the brackets are not well positioned before the orthodontic treatment it's obvious that the treatment time will increase and the final results may not be satisfactory. Because of the difficulty in access and wide anatomical variation of the lingual surfaces of the teeth it is not possible to place the lingual brackets on their ideal positions. These conditions makes indirect bonding an essential procedure for lingual orthodontics. In this review the laboratory procedures where the lingual brackets are placed on the original or on the duplicated set-up dental models are summarized

3D FEM comparison of lingual and labial orthodontics in en masse retraction

BACKGROUND: The aim of this study was to compare displacements and stress after en masse retraction of mandibular dentition with lingual and labial orthodontics using three-dimensional (3D) finite element models (FEM).METHODS: A 3D FEM of each lower tooth was constructed and located as appropriate to Roth's prescription. The 0.018-in. GAC Roth Ovation labial and Ormco 7th Generation lingual brackets were virtually bonded to the lower teeth and threaded with 0.018 × 0.025- and 0.016 × 0.022-in. SS labial (Tru-Arch form, small size) and lingual (mushroom) archwires. En masse retraction was simulated by applying 300 g of distal force from the canine to the second premolar on the 0.016 × 0.022-in. SS labial and lingual archwires. The type of finite element used in the analysis was an eight-noded brick element. The Algor program (Algor Inc., Pittsburgh, PA, USA) was used to calculate the strains and displacements at each nodal point.RESULTS: Lingual tipping and extrusion of the anterior dentition occurred with both archwires. At the premolars and first molars, intrusion, lingual movements, and lingual tipping were seen with the labial archwire, while intrusion was accompanied by labial movements, mesial tipping, and buccal rotation with lingual mechanics.CONCLUSIONS: Lingual vs. labial bracket placement influences the pattern of tooth movement, but the stress that occurs around the teeth can be accurately mapped using a 3D FEM model

Clear Aligner Appliances: Fabrication and Clinical Application

The Clear Aligner can be used to solve a minor tooth movement case and orthodontic relapse problems after treatment. It is a simple and low cost appliance which can be used by both orthodontists and general dentists. It works quickly and is comfortable for most patients. The Clear Aligner uses plastic sheets of various thickness levels. Plastic sheets are used along with a vacuum former. A set-up model is used with progressive movement of the teeth, which are positioned to ideal position. The Clear Aligner should be replaced every three weeks with a new impression taken at each visit. The Clear Aligner can carry out minor tooth movement with no brackets bonded to the teeth. Minor tooth movement including crowding resolution, space closure, arch expansion/constriction, relapsed cases, intrusion/extrusion, eruption guidance, and detailing could be done by the Clear Aligner

Romanian Aromatic and Medicinal Plants: From Tradition to Science

From ancient times, plants have been used by humans for food, fodder, fibre and medicinal purposes. Several plants were empirically considered as treatments for a large array of illness and medical conditions. Each community had specific natural remedies, based on the geographical area, environmental conditions and other factors. Thus, the use of plants can be considered as part of the intangible cultural heritage of each community. In the geographical area of today’s Romania, the ancient inhabitants, Dacians, had very good knowledge regarding the use of plants for medicinal purposes, as presented by several historical sources. The present work describes protocols for the extraction and purification of natural extracts, analytical characterisation, in vitro and in vivo evaluation of their potential applications as well as some practical examples of their application on selected Romanian native medicinal and aromatic plants. The presented results offer scientific support to their traditional use, suggesting in the same time some modern applications, for example in the nanotechnology field

THE OPTIMIZATION OF THE FORMULATION AND PRODUCTION BY EXTRUSION-SPHERONIZATION OF INERT PELLETS BASED ON MICROCRYSTALINE CELULOSE AND LACTOSE

The „design of experiment” approach to the manufacture of a product allows thesimultaneous study of formulation and process variables that significantly influence the quality of a finished product, by performing only a limited number of experiments. The aim of this study was to use design of experiment in order to optimize the laboratoryscale production by extrusion-spheronization of inert pellet cores consisting of a completely biodegradable, binary mixture of microcrystalline cellulose (MCC) and lactose (L). We have established the exact proportion of MCC, L and binder solution (a 2.5 % solution of polyvinylpyrrolidone, Kollidon K29/32 in water) and process variables (spheronization time and speed) required for the production of pellets with desired, known, preset characteristics, such as size distribution, circularity and flow behavior

The role of nucleated red blood cell, immature granulocyte count and percentage in predicting mortality in patients with acute ischemic stroke receiving thrombolytic therapy

Giriş: İnme, dünyada ikinci en büyük ölüm nedenidir. Aynı zamanda dünya çapında engelliliğin önde gelen nedenidir. Bu çalışmanın amacı; akut iskemik inme (AIS) nedeniyle intravenöz trombolitik tedavi (IVT) alan hastalarda kısa vadeli mortaliteyi tahmin etmede çekirdekli kırmızı kan hücresi (NRBC), immatur granülosit sayı (IGS) ve yüzdesi (%IG)’nin etkili bir prediktif belirteç olup olmadığını araştırmayı amaçladık. Gereç ve Yöntem: Ocak 2021-Ekim 2021 tarihleri arasında IVT alan AIS hastalar retrospektif olarak tarandı. Bu hastalar yaş, cinsiyet, inme risk faktörleri, Ulusal Sağlık Enstitüleri İnme Ölçeği (NIHSS), acil servise başvuru anında beyaz kan hücresi, NRBC, IGS ve %IG parametreleri kaydedildi. Mortalite gelişen ve gelişmeyen grup olmak üzere ikiye ayrıldı. Birincil sonuç, 1 aylık mortaliteyi içermesidir. İkincil sonuç ise semptomatik intrakraniyal kanamadır. Bulgular: Çalışmamıza acil serviste IVT uyguladığımız 61 hastadan 51’i dahil edildi. Hastaların 13’ünde (%25,5) takip sırasında mortalite gelişti. NRBC ortalaması mortalite gelişen hastalarda 0,35±0,27 iken, mortalite gelişmeyen hastalarda ise 0,01±0,05 olarak bulundu. IG ortalaması mortalite gelişen hastalarda 0,20±0,16 iken, mortalite gelişmeyen hastalarda 0,04±0,03 idi. Hem NRBC hem de IG istatiksel olarak anlamlıydı. Ayrıca iki hastada intraparankimal kanama gözlendi. Sonuç: Çalışmamız IVT ile tedavi edilen AIS hastalarında periferik kanda artmış NRBC, % IG ve IGS değerleri mortalitenin erken bir biyobelirteci olabilir.Introduction: Stroke is the second leading cause of death in the world. It is also the leading cause of disability worldwide. The aim of this study; we aimed to investigate whether an effective predictive marker of nucleated red blood cell (NRBC), immature granulocyte count (IGC), and percent (IG%) in predicting short-term mortality in patients receiving intravenous thrombolytic therapy (IVT) for acute ischemic stroke (AIS). Material and Method: AIS patients who received IVT between January 2021 and October 2021 were retrospectively screened. Age, gender, stroke risk factors, National Institutes of Health Stroke Scale (NIHSS), white blood cell, NRBC, IGS and %IG parameters at the time of admission to the emergency department were recorded in these patients. Mortality was divided into developing and non-developing groups. The primary outcome is that it includes 1-month mortality. The secondary outcome is symptomatic intracranial hemorrhage. Results: 51 of 61 patients who underwent IVT in the emergency department were included in our study. Mortality developed in 13 (25.5%) patients during follow-up. While the mean NRBC was 0.35±0.27 in patients who developed mortality, it was 0.01±0.05 in patients who did not develop mortality. While the mean of IG was 0.20±0.16 in patients who developed mortality, it was 0.04±0.03 in patients who did not develop mortality. Both NRBC and IG were statistically significant. In addition, intraparenchymal hemorrhage was observed in two patients Conclusion: In our study, increased NRBC, % IG and IGS values in peripheral blood may be an early biomarker of mortality in AIS patients treated with IVT
