POMOLOGICAL CHARACTERISTICS OF SOME APRICOT VARIETIES GROWN IN THE NORTHEAST AREA OF ROMANIA

The aim of this paper was to evaluated of some apricot genotypes grown in the Romanian North Eastern area conditions. During 2016-2018 studies were done at seven apricot cultivars (‘Mamaia’, ‘Ovidiu’, ‘Fortuna’, ‘Amiral’, ‘Goldrich’, ‘Traian’ and ‘Dacia’) which were in the experimental plot at RSFG Iaşi, Romania. Number of days and sum of the active temperature from swelling buds (51 BBCH stage) to the beginning of blooming (61 BBCH stage), trunk section area of the tree and also fruit’s weight were evaluated. Fruit weight of ‘Dacia’ registered 89.3 g but at ‘Amiral’ were 75.3 g as average for three years, but statistically there were no significant differences from the average. Regarding the period from the swelling of buds to blooming, the shortest period was of 10 days for the ‘Dacia’ and ‘Traian’ and the longest period was 14 days for the ‘Ovidiu’. The sum of the active temperatures above the biological limit has varied according to the climatic conditions of the studied years from 103°C to the ’Dacia’ and ‘Traian’ to 136°C for the ‘Ovidiu’.

Active Temperature compensation for MEMS capacitive sensor

Temperature variation is one of the most crucial factors that need to be cancelled in MEMS sensors. Many traditional methodologies require an additional circuit to compensate for temperature. This work describes a new active temperature compensation method for MEMS capacitive strain sensor without any additional circuit. The proposed method is based on a complement 2-D capacitive structure design. It consumes zero-power, which is essential toward the realization of a low-power temperature-compensated sensor in battery-powered or energy-harvesting applications<br>

Development of a Temperature-Controlled Optical Planar Waveguide Sensor with Lossy Mode Resonance for Refractive Index Measurement

The generation of lossy mode resonances (LMR) with a metallic oxide film deposited on an optical fiber has attracted the attention of many applications. However, an LMR-based optical fiber sensor is frangible, and therefore it does not allow control of the temperature and is not suited to mass production. This paper aims to develop a temperature-controlled lossy mode resonance (TC-LMR) sensor on an optical planar waveguide with an active temperature control function in which an ITO film is not only used as the LMR resonance but also to provide the heating function to achieve the benefits of compact size and active temperature control. A simple flat model about the heat transfer mechanism is proposed to determine the heating time constant for the applied voltages. The TC-LMR sensor is evaluated experimentally for refractive index measurement using a glycerol solution. The heating temperature functions relative to the controlled voltages for water and glycerol are obtained to verify the performance of the TC-LMR sensor. The TC-LMR sensor is a valuable sensing device that can be used in clinical testing and point of care for programming heating with precise temperature control.

Resources and specificity of reclamation at the coal mining spoils

The article analyses Khakassia environmental conditions with the aim to estimate their resources and role in the efficient reclamation of coal mining spoils. The availability of potentially fertile soil substrate as a resource for large-scale reclamation was evaluated by the thickness of the quaternary clay and loamy bedrock layers, taking into account the amount of the substrate needed for reclamation. The availability of resources of the potentially fertile soil substrate was carried out by taking into account the thickness and soil bulk density of the humus horizon of the most fertile soils of the region, and considering the obtained estimayes within the framework of the methodical rules and normative regulations for optimal reclamation. The availability of hydrothermal resources was estimated by active temperature sums and hydrothermal coefficient. Overall the distribution of reclamation resources was found to be very uneven throughout the region. In the south of Khakassia with its large areas occupied by technogenic landscapes the reclamation resources were concluded to be in deficit, insufficient for carrying out the reclamation according with the optimal protocols. Such lack of resources is indirectly confirmed by prevailing areas occupied by self-revegetating coal mining spoils. The article also describes some successful reclamation examples where specific local environmental conditions were used in such a way as to decrease the effect of deficient resources, thus increasing the efficacy of the self-restoration of technogenic landscapes.
