CONTRIBUTIONS TO THE RESEARCH OF THE RELATION BETWEEN AIR POLLUTION WITH NITRIC OXIDES AND THE IMPACT UPON ENVIRONMENT AND LIFE
The scientific paper presents the most significant aspects for monitoring the nitric oxides pollutant emissions and some of their environmental effects. In the present paper are pointed out some topics related nitric oxides, namely the NOx and its influence on human health. Nitric oxides are creating serious health problems for living beings, showing a risk factor of class A1 toxicity. Health problems affecting the respiratory tract, including both neck segment and lungs, are strongly based on pollution from high temperatures burning. Smoking is also the major risk factor for respiratory health problems and it is an important source of acid rains. Strategic sequences to define the multiple sources of air pollution by optimizing air structure conditions and diminishing the environmental exposure hazards are imposed to control the development of health problems. These articles present the actual data concerning nitric oxides and their influence. This pollutant gas compound is problematic due to the fact of its toxicity and contribution to particle matter formation. The risk effect combined with different contributing factors is increased when it is not alone. The present research improves the information regarding nitric oxide gas data monitor by instrumenting latest equipment in pollutant impact research. It must be a general preoccupation based on interdisciplinary studies.

34-63 CONSIDERAȚII ANALITICE PRIVITOARE LA RAPORTUL DINTRE POLUAREA AERULUI CU BENZEN ŞI CANCERUL RINOFARINGIAN

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.

Study of the influence of manufature and operational factors upon the quality of engine start, combustion and emissions generation of 1.7 CDI engine from MERCEDES VANEO

 

The present paper makes a theoretical and applied study of the components and entire engine starting and preheating system from diesel 1.7 CDI Mercedes Vaneo engine in relation with glow plugs, air filter, engine behaviour and smoke particles generation, in various cold-starting conditions and procedures, with diagnosis equipment connected to the electric and electronic management system. There is pointed out the preheating system for diesel engine with special glow plugs for air temperature increase before the fuel injection supply in the combustion chamber. These aspects have a significant influence upon the pollutant emissions production and development. Lowering the pre-combustion temperatures in the cylinder negatively influences the compression ignition process by dissipating the heat level. The opportunity for studying the pre-heating system of the Vaneo engine comes from the frequency of such a malfunction in compression ignited engines during winter cold-start.

contributions to the EXPERIMENTAL RESEARCH OF INJECTION FUEL SUPPLY SYSTEM FROM 3.0i ENGINE OF BMW X 5 ROAD VEHICLES

 

This scientific article shows the results of multiple experimental tests and researches made on the basis of fuel injection process during different operating regimes. Measured parameters are in this case engine speed, fuel consumption, injection timing and engine temperature.

The main objective of these tests is to determine how fuel consumption is influenced by engine speed and engine coolant temperature if the vehicle is operating in neutral gear that means the engine has no load on the crankshaft. In this case the engine speed will be correlated with the accelerating pedal position. The road vehicle on which the tests will be conducted is BMW X5 3.0i model years 2002. There aren’t any detailed studies made on this model. It is a well-known that a considerable number of such vehicles are registered in our country. Besides this body type, BMW Factory equipped other vehicles with this engine.

The experimental tests offer engineers a better understanding of injection process and fuel economy in the case of conventional fuel supply systems. The experimental data are summarized and accurately analyzed and represented.

31-55 EFICIENȚA UNUI SISTEM TERMO SOLAR ÎN CONTEXTUL ECONOMIC ACTUAL. CAZ PARTICULAR

ECONOMIC EFFICIENCY OF A THERMOSOLAR SYSTEM.

A CASE STUDY

 

Integration costs of a thermal solar system for domestic hot water preparation are a decisive factor regarding the implementation of the system. Integration cost depends on the size, capacity, complexity and the type of the thermal solar system. The payback period is directly influenced by the costs of conventional energy prices. Thus, this paper estimates the economic efficiency or the payback period of a thermal solar system for a household with three persons. The thermal solar system is chosen based on the three-year average monthly water consumption. The payback period is estimated based on the last three year monthly average costs of natural gas consumption.

At the beginning of last century, Romania was one of the richest European countries, among the first 10 countries that have introduced the car since its inception.

It presents the first transport vehicles in Romania dates back to 1895 are represented by two hybrid trucks with steam. „The Karaso” Simplon exotic convertible is a car made in Resita, in the style roadsters from the 50s. Vintage cars are not just cars, they can be considered on its own history on wheels, ideal combination for nostalgic times in which power was aesthetics, elegance and refinement. The oldest car in the west is a nice Ford Model A, 1928. The tradition left by the big names in automotive construction must be respected, promoting the work of some young Romanian students from technical universities and their achievements: University „Ovidius” in Constanta, Technical University „Gh. Asachi” University and University of Pitesti.

One of the contestants feared you 21st century economic market (because here are the biggest fights) is China. Among the most recent achievements of the Government in Beijing is „the three Gorges Dam” on the Yangtze River-6380 km-the third longest in the world, after the Amazon and the Nile. China’s model of economic progress transmits a significant lesson to all avid States economic charts, because progress has a price, a price so high that it cannot estimate the figures. Located in the Chinese capital, Beijing, Tian An Men Square is the biggest market in the world. Its shape is rectangular, measuring an area of 44 hectares, mainly its name and the gate that leads to the Forbidden City. China has become the second world economy taking the place of Japan in 2010, after its gross domestic Product (GDP) has exceeded that of the archipelago home islands throughout the year, according to figures announced by the Japanese Government.

20-66 SISTEME MECANICE DE ADĂPARE UTILIZATE ÎN ZOOTEHNIE

MECHANICAL SYSTEMS USED IN ANIMAL DRINKING
Any species of animals in animal breeding farms needs one ore more
types of drinking troughs (depending on the operating system) that would be
specific to its biometric characters, microclimate, and must provide physical and
social comfort. Drinker types used determines the surface that animals should
have around them. The importance of knowing the animal needs stems from
the fact that accurate information on drinking troughs can be designed to be
more efficient, more economical, more reliable or that may be more ergonomic
for the animals and thereby increase the production by a few percent, which in
the current economic conditions can mean a lot.
