Long Term Effects of the Application of Ameliorative Tillage Systems on Heavy Mechanical Composition Soils in Crop Production
There are around 400,000 hectares of soils with heavy mechanical composition, and the greatest part of the production area is under crops. The long term soil tillage by conventional methods (using plough) and a large number ...
Research of Seeding Distance Uniformity by Response Surface Methodology
The subject of this paper is to optimize the uniformity seeding distances using response surface methodology and validated optimal level variables. Variables are modeled as a vacuum on the seed plate, diameter planting ...
Stator and Rotor Power of the Doubly-Fed Asynchronous Generator Applied in Wind Power Plants
Due to the stochastic nature of the wind, doubly-fed asynchronous generator can be used effectively in the process of transforming wind energy into electrical energy, especially for the case of higher power. A special ...
Variable Rate Control System Designed for Spinner Disc Fertilizer Spreader – “Pre Fer”
The objectives of this study were: development of fertilizer rate control system which allows applying of granular fertilizer at variable rates, adopting it into a commercial granular fertilizer spreader, and then investigation ...
Using Tractor Test Data for Selecting Farm Tractors
The Nebraska Tractor Test Laboratory (NTTL) at the University of Nebraska is the official tractor testing station for the Organization for Economic Cooperation and Development (OECD) in the United States. This laboratory ...
Optimization and Research of Technological Parameters of Shut-Off Device of Biomethane Gas-Filling System
The paper gives overview of working principles, modeling and testing results of new patented shut-off device. This invention is created by co-founder of Hygen Ltd. and relies to another invention of this company, which is ...
Experimental Investigation on Accumulation of Heat by Phase Change Material in the Thermal Energy Storage
The paper includes a general discussion of reasons for the application of heat storage and phase change material as storage medium. A part of experimental results obtained by measuring during the process of paraffin phase ...
A Chaotic Profit Growth Model in the Agricultural Machines Production
The basic aim of this paper is to provide a relatively simple profit growth model in the agricultural machines production that is capable of generating stable equilibria, cycles, or chaos.
A key hypothesis of this work ...
Types, Clasification and Selection of Dryers in Agroindustry
Drying is one of the basic food processing operations in agro-industry that requires a great amount of energy for food conservation process. The large number of researchers in the domain of natural and technical sciences ...
Aerodynamic and Solids Circulation Rates in Spouted Bed Drying of Cardamom (Part 1)
Two dimensional spouted bed units with flexible bed dimensions were used with draft tubes to study spouting pressure drop and minimum spouting velocity, solids circulation rate and average cycle time. The data were collected ...
