CONSIDERATIONS REGARDING THE DEVELOPMENT OF NEW EQUIPMENT USED FOR HEMP HARVESTING

The important potential of cultivating hemp for fiber and cannabidiol extraction for medicinal use, makes this plant return to the attention of agronomists and medical researchers. Another strength of this plant is the potential of produced fibers to contribute to the decrease in the use of plastic in the near future, helping to reduce dependence on fossil fuels. In addition, hemp could be a more economically attractive alternative for ethanol generation or even for the production of high-strength construction materials. The paper aims to present several technologies used for hemp harvesting

CONSIDERATIONS ON EQUIPMENT USED FOR MORE EFFICIENT USE OF WATER IN PRECIPITATION

Soil is the element that underlies the development of agricultural activities but also of other human activities.It is the source of water supply and nutrients necessary for the growth and development of crops. the entire period of vegetation. The present work presents some of the most used equipment used in the technologies of crops of fodder plants and of grain crops. located on muddy or sloping grounds for the most efficient use of rainwater, preventing erosion and leakage.

REVIEW OF THE MAIN EQUIPMENT USED FOR SEPARATING CONTAMINANTS FROM WHEAT SEEDS, CLASSIFICATION ACCORDING TO THEIR FUNCTIONAL ROLE

Wheat seed cleaning require a complex set of operations to be performed in order to remove impurities from the grain mass and obtain high quality final products. These operations are carried out in a technological flow, starting from harvesting until the final processing stage, depending on the crop destination. The stages used to clean the wheat grain are usually following the operations: cleaning in aerodynamic separators, cleaning with sieves, sorting in indent cylinder separator, additional cleaning in special cleaning machines. The paper presents a synthesis of the primary processing phases of wheat seeds for the use in the food industry depending on their functional role

OPPORTUNITIES AND CHALLENGES TO SUSTAINABILITY IN HIDROPONIC SYSTEMS– REVIEW

Hydroponics is a viable solution to obtain intensive agriculture, in terms of producing vegetables and fruits as tasty and nutritious as those produced in classical crops. In the current changing climatic conditions, it can be a viable solution for obtaining high quality food. In addition, the system allows establishment of crops, which do not require the use of soil or manure, but only water that contains various dissolved nutrients. This agricultural cropping technology involves the use of various fertilizers instead of soil for the growth and development of plants. The light needed to develop the plates can come from the sun, or can be produced by renewable energy sources

CONSIDERATIONS REGARDING THE USE OF EQUIPMENT FOR THE ESTABLISHMENT OF WATER COLLECTION BASINS FROM PRECIPITATION AND FROM THE USE OF SPRAY IRRIGATION SYSTEMS

Global warming has been growing rapidly lately, which implies an increasing need for water for the good development of agricultural crops. To allow the recovery of a significant amount of water from rainfall or irrigation, reducing the amount of energy necessary for irrigation but also for soil losses caused by the phenomenon of erosion or puddling, works are introduced in crop technologies with the help of which this recovery can be achieved. This paper presents equipment used for the execution of rainwater catchment basins and the use of sprinkler irrigation systems

Classification of autism spectrum disorder using supervised learning of brain connectivity measures extracted from synchrostates

This is the author accepted manuscript. The final version is available from IOP Publishing via the DOI in this record.OBJECTIVE: The paper investigates the presence of autism using the functional brain connectivity measures derived from electro-encephalogram (EEG) of children during face perception tasks. APPROACH: Phase synchronized patterns from 128-channel EEG signals are obtained for typical children and children with autism spectrum disorder (ASD). The phase synchronized states or synchrostates temporally switch amongst themselves as an underlying process for the completion of a particular cognitive task. We used 12 subjects in each group (ASD and typical) for analyzing their EEG while processing fearful, happy and neutral faces. The minimal and maximally occurring synchrostates for each subject are chosen for extraction of brain connectivity features, which are used for classification between these two groups of subjects. Among different supervised learning techniques, we here explored the discriminant analysis and support vector machine both with polynomial kernels for the classification task. MAIN RESULTS: The leave one out cross-validation of the classification algorithm gives 94.7% accuracy as the best performance with corresponding sensitivity and specificity values as 85.7% and 100% respectively. SIGNIFICANCE: The proposed method gives high classification accuracies and outperforms other contemporary research results. The effectiveness of the proposed method for classification of autistic and typical children suggests the possibility of using it on a larger population to validate it for clinical practice.The work presented in this paper was supported by FP7 EU funded MICHELANGELO project, Grant Agreement #288241.

Prediction of Synchrostate Transitions in EEG Signals Using Markov Chain Models

This is the author accepted manuscript. The final version is available from IEEE via the DOI in this record.This paper proposes a stochastic model using the concept of Markov chains for the inter-state transitions of the millisecond order quasi-stable phase synchronized patterns or synchrostates, found in multi-channel Electroencephalogram (EEG) signals. First and second order transition probability matrices are estimated for Markov chain modelling from 100 trials of 128-channel EEG signals during two different face perception tasks. Prediction accuracies with such finite Markov chain models for synchrostate transition are also compared, under a data-partitioning based cross-validation scheme.The work presented in this paper was supported by FP7 EU funded MICHELANGELO project, Grant Agreement #288241

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.

CONSIDERATIONS ON ENERGETIC CROPS POTENTIAL

In order to breathe fresh and clean air, nature and terrestrial atmosphere should be preserved and protected. Carbon emissions represent one of the main enemies of air quality. Recently, carbon emissions have surpassed all the predictions because the excessive industrialization, becoming the determining factor for global warming. A viable alternative to carbon emissions reduction is the utilization of energy sources that can diminish the noxious substances emissions up to zero. This can be done by using the power of wind, sun, water, energy plants, etc. Among the energetic potential plants, the biomass is obtained- a form of renewable energy which final product is biofuel
