Abstract: This study was designed in response to REG / 110-2008 CE parameters on the classification of the physico-chemicalindustrial spirits, alcoholic drinks made from refined alcohol fermentation food, with or without added flavors, foodcoloring and sugar. This regulation was developed after finding that spirits fraud obtained by small producers in theempirical method, with operating facilities in discontinue distillation, without complying with the basic principles ofoperation of the distillation, the excess of the permissible toxic components. In this respect, we refer to methanolpoisoning, the most frequently encountered are the same as acquiring organoleptical reason why ethanol can not bedetected in any sensory considerable doses. At a dose of 30-50 mg methanol / kg, after a latency of approximately 1hour the following symptoms: headache, violent abdominal pain, agitation, delirium, coma and hypothermiaacidolitic . So the person survives poisoning, blindness occurs suddenly or gradually installed as a result ofmetaboliz rii liver under the influence of methanol alcooldehidrogenazelor resulting formic acid and finalformoldehidrogenaze that destroy the optic nerve or transient by blocking enzymes happy (citocromoxidaza) in largequantity in the eye.

Abstract: The aim of this paper is to determine the degree of microbial charge of the air in a bread factory. In food industry theair represents one of the biggest riscs of microbiological contamination (with bacteria, yeast, mildew) of food productswith repercusions in the sanitary area (intoxications) as well as in industrial area (modification of organolepticproperties of products, rebutting in fabrication, depositing problems, etc. For food industry it is very important that theair is not filled with microorganisms, because these microorganisms are moving in this space and they arrive on rawmaterial and on the finished product.The product about to be fabricated can constitute the medium of culture for themulticplication of microorganisms if the conditions of temperature and humidity are favourable. Generally one mustavoid as much as possible the phenomenon of stagnation of products in contact with surfaces and air.Thebacteorological analysis of air happens usually and especially in rooms where the aerial transmitting of infections mustbe avoided because it constitutes a means of control of sanitary conditions.For the bacterial content of air there are nostandards so far. There have been made propositions based on researches with the help of which we can estimate thedegree of contamination of the air in production spaces.In food industry the number of mezofil germs must not surpass600/ m3 and the fungus 300/m3.
Romanian press about life concert of Timi oara inter-war period
Studii de Stiinta si Cultura , 2011,
Abstract: The musical chronicles from interwar period impresses trough the great names of artistswho have sung in Timisoara and the militancy of the musical editors. This way it is announced thegreat availability of Romanian musical art to connect the western art and to recover the historcalretardation wich separated us, and, not least, the people ability to communicate through thecommon language of art.
Mihail Jora, creator of Romanian ballet prototype
Studii de Stiinta si Cultura , 2011,
Abstract: The idea to use in the ballet performances topics related to the Romanian music and life came through Mihail Jora’s creations: La pia ” (1928), Demoazela M riu a” (1940), Curtea Veche” (1948), Cand strugurii se coc” (1953), ntoarcerea din adancuri” (1959), Hanul Dulcineea” (1966). His works are characterized by creative force, subtlety and staging gift that have turned the trivial into art. The dramatic sense, the picturesque force, the complex rhythm, the harmonious coloring, the conducting talent and the gentle use of sounds as well as the modern aesthetic vision - all speak about an artistic personality of an extraordinary originality.
Forecast Intervals for Inflation in Romania
Mihaela BRATU
Theoretical and Applied Economics , 2011,
Abstract: In this paper I built forecasts intervals for the inflation rate in Romania, using the quarterly predicted values provided by the National Bank of Romania for 2007-2010. First, I used the historical errors method, which is the most used method, especially by the central banks. Forecast intervals were built considering that the forecast error series is normally distributed of zero mean and standard deviation equal to the RMSE (root mean squared error) corresponding to historical forecast errors. I introduced as a measure of economic state the indicator – relative variance of the phenomenon at a specific time in relation with the variance on the entire time horizon. Then, I calculated the relative volatility in order to know the change that must be brought to the root mean squared error in order to take into account the state of economy. Finally, I proposed a new way of building forecasts intervals, when the date series follows an autoregressive process of order 1. In this case the length of forecasts interval is smaller and I got a slightly higher relative variance. I consider really necessary the building of forecasts intervals, in order to have a measure of predictions uncertainty, which is quantified by the National Bank of Romania using the prediction intervals based on a simple methodology. I calculated the forecasts intervals using MAE (mean absolute error), the indicator chose by National Bank of Romania and the MSE (mean squared error) indicator.
Forecasting inflation in Romania to improve the monetary policy
Bratu Mihaela
Medjunarodni Problemi , 2012, DOI: 10.2298/medjp1202131b
Abstract: Based on data of inflation forecasts provided quarterly by the National Bank of Romania, forecast intervals were built using the method of historical forecast errors. Forecast intervals were built considering that the forecast error series is normally distributed of zero mean and standard deviation equal to the RMSE (root mean squared error) corresponding to historical forecast errors. The author introduced as a measure of economic state the indicator- relative variance of the phenomenon at a specific time in relation with the variance on the entire time horizon. For Romania, when inflation rates follows an AR (1), She improved the technique of building forecast intervals taking into account the state of the economy in each period for which data were recorded. The author concludes that it is necessary to build forecasts intervals in order to have a measure of predictions uncertainty.

Abstract: The simple econometric models for the exchange rate, according to recent researches, generates the forecasts with the highest degree of accuracy. This type of models (Simultaneous Equations Model, MA(1) Procedure, Model with lagged variables) is used to describe the evolution of the average exchange rate in Romanian in January 1991-March 2012 and to predict it on short run. The best forecasts, in terms of accuracy, on the forecasting horizon April-May 2012 were those based on a Simultaneous Equations Model that takes into account the Granger causality. An almost high degree of accuracy was gotten by combining the predictions based on MA(1) model with those based on the simultaneous equations model, when INV weighting scheme was applied (the forecasts are inversely weighted to their relative mean squared forecast error). The lagged variables Model provided the highest prediction errors. The importance of knowing the best exchange rate forecasts is related to the improvement of decision-making and the building of the monetary policy.
Moral Judgment: Truth, Order and Consequence  [PDF]

Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.65061
Abstract: Often we make snap moral judgments based on limited information. For instance upon reading a newspaper headline we very quickly decide on whether the implied outcome is good or bad. However, in situations like this we are also likely to revise our judgments when we read the main story and the conclusion of the article. One question yet to be answered is whether we adjust our moral judgments in a systematic way as we gain more details about a moral scenario. Two experiments (lab-based, online) addressed this question along with the influence of other factors on moral judgments (the origin of the moral scenario, the severity of the consequence of the scenario). Across both experiments, moral judgments were: 1) generally adjusted downwards as more information was presented; 2) more severe for headlines than the main story or the conclusion; 3) more severe for scenarios that were fabricated than real life stories; 4) more severe when the conclusion involved a severe consequence than a non-severe consequence.
Dynamic Moral Judgments and Emotions  [PDF]
Magda Osman
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.68090
Abstract: We may experience strong moral outrage when we read a news headline that describes a prohibited action, but when we gain additional information by reading the main news story, do our emotional experiences change at all, and if they do in what way do they change? In a single online study with 80 participants the aim was to examine the extent to which emotional experiences (disgust, anger) and moral judgments track changes in information about a moral scenario. The evidence from the present study suggests that we systematically adjust our moral judgments and our emotional experiences as a result of exposure to further information about the morally dubious action referred to in a moral scenario. More specifically, the way in which we adjust our moral judgments and emotions appears to be based on information signalling whether a morally dubious act is permitted or prohibited.
