Testing the Relationship between Public Expenditure and Economic Growth in Romania

In this paper we analyze whether the Romanian economic context confirms the Armey model, and present the relationship between public spending and economic growth that may offer a suitable basis for decision makers. The analysis is based on both annual and quarterly data regarding public spending and economic growth in Romania. After investigating the correlation validity, the analytic results did not confirm the premises related to the Armey Curve for the Romanian context during 1990-2011. However the time interval is marked by unpredictable phenomena such as the transition from the state economy to the market economy and the world financial crisis, both is altering the results. The fact determines us to search the coordinates for developing a new model that describes better the connections and the period characteristics

The Effect of Platelet-Rich Plasma Injection on Short Term Vocal Outcomes Following Phonosurgery—A Pilot Study

Background and Objectives: The efficiency and optimal voice rest period following phonosurgery remains debatable. Platelet-rich plasma (PRP) is a safe and cheap alternative to many bioactive agents being studied on animal models, and is already in use in many medical areas. We investigate the short-term effects of PRP and voice rest on voice outcomes following phonosurgery as an alternative to voice rest alone. Materials and Methods: A prospective single-blinded pilot study was conducted. Sixteen patients with a diagnosis of vocal fold cyst and polyps were included, forming equal groups (PRP and voice rest vs. voice rest alone). Voice analysis was carried out on the preoperative day, day three, and week three following surgery. The measured parameters were fundamental frequency (F0), noise–signal ratio (NSR), harmonic poverty (HP), attack alteration (AL), pitch instability (PI), and amplitude instability (AI).VHI(Voice Handicap Index)-30 questionnaires were carried out before surgery and three weeks following surgery to assess the impact of subjective voice change on quality of life. PRP was obtained using commercial kits with separator gel. Results: An average 3.68-fold increase in platelets was obtained with PRP. No side effects were noted after injection. All voice parameters improved on day three and week three following surgery. Statistical significance was noted only in the fundamental frequency of male patients (p = 0.048) in favor of the PRP-voice rest group. In addition, the VHI- 30 questionnaire results between preoperative and postoperative assessments showed statistically significant differences in total VHI score (p = 0.02) as well as the physical (p = 0.05) and emotional (p = 0.02) scale in favor of the PRP-voice rest group. Conclusions: PRP presents short term safety in patients who undergo phonosurgery, although long-term outcomes are unknown. PRP and voice rest are superior to voice rest alone when considering subjective assessment of the voice. When analyzing acoustic parameters, PRP and voice rest are not superior to voice rest alone

Synergistic Effects in Nanoparticle-Based Protective Coatings for Paper and Textiles

Superhydrophobic materials have attracted considerable attention during the last decades,since they allow the facile transfer of special wettability properties on various surfaces [...

Preliminary Data on the In Vitro Effect of Copper-Based Compounds on Aerobic Bacterial Microflora Isolated from Sheep Footrot

Contagious sheep footrot is an infectious disease with chronic evolution, usually enzootic, characterized by necrotic or necrotic-purulent inflammation of the soft tissues of the hoof, which causes partial or total detachment of the horn. Cu-based products represented by (I) 1-hydroxyquinoline + Cu on 5% hydroxyapatite, (II) 2 Hydroxyquinoline + Cu + NO3 on 5% Hydroxyapatite and (III) 3 Nitrohydroxyquinoline + Cu on 5% Hydroxyapatite were conditioned in aqueous suspension in a volume of 100 ml, pH 6,0 – 6,4. The products were placed into wells, 20 μL/well, along with 0.5 % copper sulphate solution (Cu control) and Enroxil and Oxitetracycline (control for antibiotics). The results demonstrated that 7 of the samples (58.33 %) are sensitive to the product I, 6 samples (50%) to the product III, 4 samples (33.33 %) to the product 2 and the 0.5% Copper sulphate solution only has a bacteriostatic effect. In comparison to the two antibiotics, 9 samples (75 %) are sensitive to enrofloxacin and only 5 samples (41.66 %) to oxytetracycline. Regarding the associations of microorganisms in the samples with resistance, we have found that these are represented by the most common germs of genus Bacillus, Corynebacterium and Gram negative bacteria, and rarer associations with Micrococcus and Staphylococcus

REPUTED DENTISTS AND / OR SPECIALISTS IN THE ORO-MAXILLO-FACIAL FIELD WHO WORKED IN FRENCH CIVIL AND MILITARY HOSPITALS DURING THE FIRST WORLD WAR (1914-1918)

The First World War was and is considered the most terrible conflagration of all time. Thus, over 65,000,000 soldiers made up the corps of land armies, naval and air forces, combat armies that participated in the conduct of military operations during the First World War. About 8,500,000 people died and more than 21,000,000 were injured. France was one of the countries most affected by this war, its medical services, including dentistry and oral and maxillofacial surgery, being completely obsolete. Thus, in this material, we tried to describe some important figures of French oral and maxillofacial dentistry and surgery, which were active in French civil and military hospitals during the First World War (1914-1918)
