RESEARCH OF THE MAIN PROCESSING WORKS FOR ESTABLISHING A JERUSALEM ARTICHOKE CROP ON DIFFICULT AND CONTAMINATED SOILS

Jerusalem artichoke, is a technical plant that have some special features which make it suitable to be cultivated on degraded and difficult soils. However, processing difficult lands can cause major problems for farmers, in terms of using the right technology and reducing investment costs. The paper aim to address to the main challenges faced in preparing the soil for a Jerusalem artichoke culture, in order to maximize the productivity and efficiency

CONSIDERATIONS REGARDING THE IMPORTANCE OF THE SORTING OPERATION OF FRUITS AND VEGETABLES

For the normal development of daily activity and maintaining health, the body needs a certain amount of energy and complete nutritional factors (proteins, carbohydrates, lipids, vitamins, minerals, water). They are obtained from food, fruits and vegetables occupying a prominent place as a natural source of carbohydrates, alkalizing mineral salts, vitamins and water. Conditioning involves a set of operations aimed at bringing the products to the characteristics provided by standards, specific to a certain direction of capitalization. This article describes the operations included in the conditioning process, the role and importance of presorting and sorting fruits and vegetables, as well as equipment for these operations

RESEARCH ON THE DETERMINATION OF THE NOISE LEVEL PRODUCED BY AN ATOMIZER IN DIFFERENT FUNCTIONING CONDITIONS

Noise is one of the priority issues of environment, especially in crowded urban zones. The user is more and more informed and prefers to choose some reliable products with low noise level. A low level of acoustic pollution leads to the environmental and consumer health protection satisfaction level and thus increases the quality of marketed products. 2000/14/E Directive it requires manufacturers to apply to each equipment introduced on market the guaranteed value of the acoustic power.In this regard, the paper consists both in measuring the acoustic power level of the atomizer at maximum speed and idling. Also, in the paper will be specified choosing the method, number and place of the used microphones, calculating the average of the acustic pressure, functioning conditions, and incertitude measuring
