For agrarian economies such as India, the quality of the soil is critical for maximized yield sustainable cultivation. When a large area is utilized, sample testing of soil is essential. The use of a robotic system for sampling is vital for saving time and replacing manual laborious work. This work represents a robotic system that was deployed for soil sample collection. A mechanical soil sampling and storage system based on augers and turntable storage is used in the system. Using a GPS-driven algorithm, the robot navigates autonomously to desired sampling locations. It collects data from the sampling area using sensors connected to an Arduino board. A proof-of-concept demonstrator proved that such a solution can be successfully scaled and deployed, which will aid in more efficient cultivation and sustainable agriculture.

The problem of grain storage and storage can be approached from two perspectives: storage and storage of cereals and technical plants within individual agricultural holdings; storage and storage of cereals and technical plants within agricultural associations and companies. At the level of Romania, the storage and storage of cereals at small agricultural producers are deficient in terms of ensuring optimal storage conditions according to standards. These variants include: preservation at low temperatures; preservation by active aeration; self-preservation; chemical preservation; conservation with the help of radiation. In the paper we will approach the conservation by active aeration because it folds better for small agricultural producers. Proper aeration is one of the most important processes in a grain storage system and is essential for maintaining the quality of stored products. Aeration means the movement of a relatively small volume of air through the grain mass in order to control the temperature of the grain and to reduce the risk of product degradation. The two main objectives of aeration are to maintain a uniform temperature in the grain mass and at the same time the temperature must be as low as possible from a practical point of view. The paper will present the results of experiments for storing bulk grain in a metal cell with central aeration system, which is based on a patent. This type of storage system can be used successfully in small agricultural producers.

The global energy trends are currently dominated by a massive use of fossil non-renewable energy sources which are progressively depleting. In this way, the production of second-generation biogas production from organic wastes by the dark fermentation process offers, therefore, an attractive solution to diversify the present energy mix. The development of biogas production units has led to an increase in the quantity of biomethane, but it contains impurities. A biomethane purification and storage system was developed in this work to improve the quality of this biofuel. Solutions were first developed to capture carbon dioxide, hydrogen sulfide, water, and volatile organic compounds found in the initial biogas. These solutions were based on a system of purification made up of water absorption reactions and iron oxide, activated charcoal, and steel wool adsorption. Thus, the biomethane obtained after purification has been stored in an inflatable balloon before being compressed into a refrigerant bottle of R134a. The treatment system was used to release a biogas with 95 % biomethane and a law heating value (LHV) of 54 MJ/kg after purification. It also emerges that purification of 2 m3 of biogas requires 0.15 m3 of water at 20oC to produce 1.4 m3 of biomethane. This biomethane can meet an energy demand of 1624 Wh or 0.2 m3 of daily biomethane requirements. The system as a whole can allow customers with a biodigester to produce their own energy (cooking or electric) while reducing the production of green-house gases in the atmosphere.

This article refers to the traditional solution of the non-dismantable sampler and to the dismantable sampler applied as a new solution. This research describes the results of a research project on how the structure of the sampler for assembling and storage of LPG samples influences the representativeness of samples under study. The research was carried out in two directions : analysis of gas samples for the current PN-EN 589, PN-EN ISO 4257 standards and analysis of microscopic and macroscopic inner surface of the sampler. It was observed the formation of contamination layers in samplers. The chemical composition of the layers was examined and identified possible impact on changing the quality parameters of LPG. Based on the conducted research and analysis, the impact of the changed structure on the quality parameters of the LPG fuel and its representativeness in reference to the part of the cargo from which it had been taken can be assessed. Allow to conclude the thesis that the structure of the dismantable sampler followed internal cylinder surface treatment affects the representativeness of the samples collected and analyzed type of LPG gas. The construction of the sampler and possible of cleaning sampler is particularly important for qualitative parameters such gases as corrosive to copper and sulfur content of the total. Impurities that may be present in LPG, derived from refinery and petrochemical processes (ammonia, water, sulfur, methanol, higher hydrocarbons, dirt) and the distribution system are causing the occurrence of secondary reactions. Results occurring secondary reactions adversely affect the quality of the LPG. The researched solution on the dismantled sampler was patented, implemented, and applied in practice. The possibility to dismantle and thoroughly clean the sampler prior to sample collection enhances the certainty of obtaining highly representative samples and credible test results.

Alternative sources such as buccal cells have already been tested for genetic studies and epidemiological investigations. Thirty-seven volunteers participated in this study to compare cytology brushes, mouthwash, and treated cards for DNA collection. Quantity and quality of DNA and cost and feasibility were assessed. The mean DNA yield at 260 nm was found to be3.5,4, and2.6μg for cytobrushes, mouthwashes, and treated cards, respectively. A second quantification technique by fluorescence showed differences in the DNA yield with1.1and5.2μg for cytobrushes and mouthwash, respectively. All buccal samples allowed isolation of DNA suitable for polymerase chain reaction. According to the procedure of sample collection, the yield and purity of collected DNA, and storage conditions, the use of cytobrush appears to be the more appropriate method for DNA collection. This protocol has been validated and is currently applied in three large-scale multicentric studies including adults or children.

Waterborne basecoat is gaining popularity in the automative industry. However, the viscosity of some waterborne basecoats may be unstable while circulating in the paint supply-and-storage system. This instability has caused significant problems in the paintability of the basecoats and the quality of the final finish. An original application of forecasting control is implemented to control the viscosity of certain waterborne basecoat. Both manual and automatic implementations of forecasting control result in significant improvement of process capability.

Introduction In electron microscopic investigations of crystalline specimens the direct observation of the electron diffraction pattern gives additional information about the specimen. The quality of this information depends on the quality of the crystals or the crystal area contributing to the diffraction pattern. By selected area diffraction in a conventional electron microscope, specimen areas as small as 1 µ in diameter can be investigated. It is well known that crystal areas of that size which must be thin enough (in the order of 1000 Å) for electron microscopic investigations are normally somewhat distorted by bending, or they are not homogeneous. Furthermore, the crystal surface is not well defined over such a large area. These are facts which cause reduction of information in the diffraction pattern. The intensity of a diffraction spot, for example, depends on the crystal thickness. If the thickness is not uniform over the investigated area, one observes an averaged intensity, so that the intensity distribution in the diffraction pattern cannot be used for an analysis unless additional information is available.

Harvest quality of sugar beet varies according to soil conditions, harvester type and setting, and variety, too. Harvest quality may affect storage losses, in particular when injuries occur. To determine the harvest quality of commercial sugar beet and to quantify resulting storage losses, 92 commercial sugar beet clamps were sampled across Germany and information about harvest conditions were gathered. At IfZ, soil tare, leaf residues, topping diameter, root tip breakage and surface damage of the beets were determined. The beets were stored in 6 replicates in a climate container at 9°C for 10 weeks. The results demonstrate a rather good harvesting quality of sugar beet in Germany. Soil moisture at harvest did not affect harvest quality and storage losses. Very light, but also heavier soils lead to inferior harvest quality (soil tare, root tip breakage, damage) and slightly higher storage losses compared to the typical loam soils. Significant differences occurred between the three harvester types (companies). In general, high root tip breakage and severe surface damage of the beet was related to a high infestation with mould and rots, high invert sugar contents after storage and high sugar losses. Out of the five most planted varieties, in particular one turned out to be very susceptible to damage, resulting in high storage losses. The factor analysis suggests that the effect of harvester / harvester setting and of variety is more important for harvest quality and storage losses of sugar beet than soil conditions at harvest. Therefore, attention should be paid to optimize these conditions.
