THEORETICAL ASPECTS OF THE AERATION DRYING PROCESS WITH APPLICATION IN THE HAY TECHNOLOGY

In the current context of the development of mechanized agriculture in several directions in the field of feed storage needs appear in the effective implementation of the drying method used. In terms of maintaining higher production achieved by reducing losses of fodder harvesting and secondly by increasing the number of cycles of harvest due to reduced time of harvest (representing the time elapsed mowing fodder plant and to store hay), outline the need for a more careful study of the drying process. This paper presents some theoretical aspects that determine and control the drying process used in technology of hay

TECHNICAL ASPECTS ON DYNAMIC BEHAVIOR OF THE SEMITRAILERS WITH SUSPENSION HITCH

An efficient means of transport, over short distances and heavy-duty traction on roads maintained or unmaintained field, agricultural land is considered system tractor - trailer. This article presents the results of experimental research on the dynamic behavior of the system tractor - trailer suspension system provided with agricultural roasted. The variety of constructive solutions for hitches with suspension motivated interest in experimental research of the effects caused by the introduction of elastic elements (leaf springs), fried farm semitrailer. They studied three variants of hitches compared with suspension and without suspension version. To highlight how it influenced the dynamic behavior of the studied system, were determined and analyzed for the following parameters: its spectrum of frequencies, maximum amplitude of vertical acceleration root mean square of the accelerations respectively

Aplicacion del silicato tricalcico como una alternativa biocompatible.

El seleccionar un adecuado material para la obturación apical es un acto fundamental para la resolución de un caso con una lesión periapical persistente; los principales factores que deberá tener este material es su biocompatibilidad y el crear un sellado hermético para evitar filtración; deberá poseer capacidad para inducir osteogénesis y reparación, no desarrollar toxicidad, ser radiopaco y bacteriostático. El Biodentine es un material recientemente introducido al mercado (2011), principalmente compuesto de silicato tricálcico. Es usado para tratamientos de reparación en corona y raíz, reparando perforaciones, resorciones, empleado para apexificaciones y como material de retroobturación; también puede ser utilizado como un sustituto de dentina en caries demasiado extensas.

CONSIDERATIONS REGARDING THE GENERAL RULES OF PROPER EXPLOITATION OF TYRES FROM THE AGRICULTURAL EQUIPMENT

With the development of mechanized agriculture involving the use of self-propelledmachinery with powers and large capacities, the soils are subjected to intense compaction processes, especially when these have high humidity. In this context the rational use of tires represent one of the measures of reducing the compaction and also the fuel consumption and implicitly the environmental pollution, this paper presenting a set of general rules intended to support the operators so that the characteristics of the machine to be used at full capacity, with optimal consumptions of resources

EXPERIMENTAL RESEARCH ON ENERGY AND OPERATING PARAMETERS OF THE TILLER M7.5 + REVERSIBLE PLOW PR1 AGGREGATE

This paper shows some information about the experimental research made todetermine the operating parameters of an aggregate which consists of a 7.5 hp tiller, symbolized M7,5 and a reversible plow with a band, symbolized PR1. The researches were carried out in real working conditions, the ultimate goal being to promote the marketing of the mentioned machine. To achieve optimal conditions for growing plants in general, and vegetables particularly in small farms and individual households, a good quality plowing it’s essential. This work can be realized with smaller equipment and addequate working capacities such as tillers in aggregate with technical working equipments, these being the ideal solution to meet the needs of small farmers

THEORETICAL RESEARCH REGARDING THE WORKING PROCESS OF THE FERTILIZERS MANAGING SYSTEMS BY CENTRIFUGATION

Achieving a distribution standards per hectare as uniform and as specified by eachculture is the most important objective when it comes to administering fertilizer machine. In this sense the paper aims to highlight the theoretical and experimental research conducted by specialists from home and abroad on the process of working machines administrator chemical fertilizer granulation, according to parameters that can influence this process: as blades, the angle of their and so on

RESEARCH CONCERNING THE ACHIEVEMENT OF SOME APPLES SORTING EQUIPMENTS

According to the present interest of the government to encourage the fruitconsumption by the scholars, especially the apple consumption, two functional model of technical equipment for sorting apples have been designed, manufactured and tested in INMA Bucharest. These equipments can be used for sorting also others fruits with spherical shape such as oranges, peaches, grapefruits etc. The mechanized sorting process conducts to valorisation of the farmer’s production and to increase their turnover, thus is necessary to analyse and improve this process, by optimizing the working parameters
