SUBLIMINAL PERCEPTION AND EXTERNAL FACTORS IN TV COMMERCIALS

       In this paper we examined the subliminal perception of exposure to TV commercials and identified which variables cause consumers to take the buying decision. We conducted an experiment that highlighted the fact that, besides the subliminal perception of advertisements, external factors have an important role. By the descriptive method we have highlighted the mechanisms that contribute to the positive perception of the brand. Novelty is precisely the extension of this concept of subliminal advertisements in the cognitive field, in the processing of information and in behavioral change as a result of exposure to TV commercials and external factors.

IMPROVING THE TIME-FREQUENCY READING OF THE SIGNALS USED TO DETERMINE THE DYNAMIC STIFFNESS COEFFICIENT

The objective of the paper is to describe and determine the Fourier transform to define a passage relation of a signal from the time domain to a frequency domain. The process allows the identification of frequencies but does not provide complete information about the behavior of the system, in the sense that it does not allow the interpretation of frequency evolution over time. For this reason, I propose the use of time-frequency analysis.

35-61 ASPECTE PRIVIND UTILIZAREA ENERGIEI SOLARE Partea I

ASPECTS ON THE USE OF SOLAR ENERGY – Part I

Most human activities, the size, volume and quality of goods and services available to mankind are energy dependent, with energy playing a central role in human existence, being the most important resource. At present, fossil fuel carriers are the fuel of the world economy, and humanity is geared towards using abundant energy at a relatively low price. Alternative sources such as sun, wind, hydropower, wave energy, geothermal energy, bioenergy etc. it is practically not consumed, calling it renewable (alternative or unconventional sources). They produce far fewer emissions, reduce chemical, thermal, and radioactive pollution, and are available theoretically anywhere in the world. The sun is a real blessing, giving us in an hour – enough energy for all people to use it for one year. Every day, about 120,000 terawatts (TW) of electrical power is offered to us by the sun. That, while over a year, the world uses only 15 TW of energy. The paper analyzes some aspects regarding the use of solar energy: collectors, solar power stations, solar houses.

EFFECTS OF LONGITUDINAL MECHANICAL VENTILATION ON THE FIRE SMOKE MOVEMENT IN A SUBWAY TUNNEL

The smoke and toxic gases released from a subway fire contain a number of harmful elements to the human body. Thus, long-term smoke exposure is the main cause of the large number of casualties in such an event. To protect the lives of people caught by a fire in the subway, it is necessary to use smoke evacuation systems. Thus, longitudinal mechanic ventilation systems can be used. During the use of these systems, the smoke movement inside the tunnel is characterized by phenomena such as backlayering, reverse flow or bifurcation flow.

35-76 ASPECTE PRIVIND MIȘCAREA FUMULUI GENERAT DE INCENDIU ÎN STAȚIILE DE METROU

ASPECTS OF FIRE SMOKE MOUVEMENT IN SUBWAY STATION

The development of computer applications in the field of fluid dynamics has led to increased numerical fire simulations in underground stations, tunnels or underground structures. From a constructive point of view, the subway stations are characterized by large openings, by which they enter sufficient amounts of air, which can, in the case of a fire, either to feed with oxygen combustion or to contribute to the evacuation of smoke. When a fire is held in a subway station, the amount of smoke emitted usually floods the subway station or the tunnel (depending on the place of the fire outbreak), including the evacuation routes of passengers. This leads to reduced visibility and can cause deaths from smoke intoxication. Thus, one of the main concerns is the protection of the escape stairs from the danger represented by the smoke emitted from the fire. On the other hand, it is essential that firefighters reach as close as possible to the fire outbreak and extinguish it.

DETERMINATION OF FLOW RATE AT LOW HEAD HYDRO POWER PLANTS FEATURE WITH KAPLAN TURBINES

In the paper there are presented some methods of determination of the flow rate measurements in low head hydro power plans are also presented with a series of field studies. The most commonly used method for determining the flow in convergent measurement sections is the multipoint velocity measurement with propeller type current meters. For flow rate evaluation integration of the difference between measured velocities and a known velocity distribution is recommended. One of the newest methods of flow determination in intakes is the acoustic scintillation method, a cross-correlation method. For accurate results the scintillation method must be installed downstream of trash racks. Another method that can also be adopted to measurements in low head, is method of acoustic transit measurement, but new procedures for determination weighing the individual path velocities have to be applied due to varying shape of the flow cross sections. At the end of the paper a comparative analysis is made between the methods for determining the flow rate in the convergent measuring sections

ANALITIC CONSIDERATIONS REGARDING THE LINK BETWEEN AIR POLLUTION WITH BENZENE AND NASOPHARYNGEAL CANCER
The analytic paper presents the important aspects and relations for reporting the benzene pollutant emissions and some carcinogenic effects. In the present work are outlined some aspects of a particular molecular mixture between 6 atoms of carbon and 6 atoms of hydrogen, namely the benzene and its influence on health state. Benzene is a carcinogen for humans, class A1 of toxicity. Cancers affecting the respiratory tract, including both nasopharyngeal cancer and lung cancer, are strongly associated with pollution from coal and other solid fuel burning. Tobacco has been viewed as the major risk for respiratory cancers and it is an important source of benzene. Preventive steps to curtail the many sources of air pollution by improving living conditions and reducing the occupational exposure hazards are markedly needed to control the incidence of respiratory cancers.
This article presents the state of the art knowledge regarding benzene and its influence. It is a carcinogenic pollutant, because it has a high level of toxicity. The negative carcinogenic effect compared with other factors is accelerated when paired with multiple pollutants. The present paper enriches the knowledge regarding benzene emission reporting by using latest technologies in environment impact control. This has to be a global effort based on multidisciplinary approaches.

34-51 CONTRIBUȚII LA ANALIZA STATISTICĂ A PARCULUI AUTO ȘI A POTENȚIALULUI TRANSPORTURILOR PE PLAN NAȚIONAL ȘI LOCAL

CONTRIBUTIONS TO STATISTICAL ANALISIS OF AUTOMOTIVE SECTOR AND TRANSPORT POTENTIAL ON NATIONAL AND LOCAL LEVEL
The statistical analyze made in this paper shows the significant aspects, values and potential for development and investments in transport sector on national and local levels in Romania, with consideration of their influence also on the environment. The transport is one of the most developed activities developed by humans. It affects everybody and also the environment as a whole. Our country is focusing right now on transport activities, because since 2007, after integration there are increasing preoccupations for import and export activities. Predominantly importing materials and goods needs a lot of transportation to be made. Also people traveling between countries also need transportation and vehicles to do these trips. Many companies have been developed in the last 2 decades in order to meet these requirements of the market. There are no studies to show how far has been gone with this transportation development and which is the trend. The economics is close related to the transport activity or else it would not be done. The environmental impact is also great with high transportation activities, even if there are newer vehicles registered every year. The present paper shows the vehicle registration both in Cluj and on national level for different types of vehicles, especially those which are negatively impacting the environment and the economic activities, the market and society.
