Optimization of the Electrical Parameters of Silicon Heterojunction Solar Cells
We used the AFORS-HET simulation program for hetero-junction solar cells modeling to determine how the thickness and material properties of the n-, i-, and p-layers affect the electrical parameters and the device performance. ... -
Respiratory Behaviour of Mature Light Green Guava (Psidium Guajava L.) under Closed System
Respiratory behavior is an important aspect in designing and operating systems such as controlled and modified atmosphere storage that will extend the shelf life of the perishable produce. The respiration rate and respiratory ... -
Results of Preliminary Laboratory Studies After Pre-Sowing Electric Treatment of Pea Seeds
In many countries, the possibilities for stimulation of the sowing qualities and yield of cultivars after pre-sowing electric treatment of their seeds have already been identified. At the University of Ruse, Bulgaria, ... -
The Role of the Strategy in the Innovation Ability of the Hungarian Agricultural Machinery Manufacturers
The current production of the Hungarian agricultural machinery manufacturing sector, which used to see better days, lags behind the production of the previous years to a great extent. The organisational structure of the ... -
Soil Moisture Influence on the Energy of Agricultural Processes
This article exposes the results related to one of the issues left open after a series of articles mentioned in the bibliography, which occurred in the years 2011-2013. A series of articles that were mentioned before ... -
Spectroscopic Approach of Winter Wheat (Triticum Aestivum L.) Nutrition and Pest Control
Laboratory reflectance spectroscopy is a routine evaluation technique in many scientific areas. The objective is to present the capabilities of a portable spectro-radiometer which can be used both for field and laboratory ... -
Theoretical and Experimental Research of Strength of Soldered Joints (Metal of Share – Metal Ceramics)
This article presents theoretical estimate of soldered strain and the obtained equivalent stresses distributions along the share length. It is suggested to estimate the soldered joints strength taking into consideration ... -
Using the Glass Fibres in Recycling Agricultural Plastic Waste
The wide-spread presence of plastic material in municipal and agricultural waste has significantly raised the ecology concern in Europe leading to laws and regulations aimed at controlling and reducing waste production, ... -
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 ... -
Water Droplets Analysis: the Classical and Quantum Hydrodynamic Frameworks
The design of a sprinkler irrigation system is always associated with a full understanding of the kinematics of the droplets during their aerial path. Resolving this problem involves both theoretical and experimental ...
