IMPROVING THE CIRCUITRY OF HIGH-PRECISION HIGH-SPEED ACOUSTO-OPTIC LASER INTERFEROMETERS OF DISPLACEMENTS WITH FREQUENCY MATCHING OF COMPONENT BLOCKS AND DOUBLE HETERODYNING AT PHOTOTRANSFORMATION STAGE

The article discusses the development of the circuitry of acousto-optic (AO) laser displacement interferometers (LDI) and the values of resolution and speed of controlled displacements achieved by them.The issues of frequency matching of Amino Acids blocks of AO LDI are discussed: AO modulator, photodetector device (FDD) and frequency generator.The

The objective of this study was to determine the demographic, clinical and survival characteristics and to identify risk factors for mortality due to tricuspid valve dysplasia in UK dogs.Records of client-owned dogs diagnosed with tricuspid valve dysplasia at a referral centre were retrospectively reviewed.Only dogs diagnosed with tricuspid valve H

Adsorption refrigeration systems were developed as an alternative to traditional Crackers vapor compression systems, offering reduced energy consumption and using refrigerants that are less harmful to the environment.Of late, sustainable low-carbon cooling technologies are being widely researched for fulfilling the rapidly expanding cooling require

In the Ecuadorian province of Azuay, agro-ecology seems to signal towards the rebirth of family agriculture in Maps a context of regional migration.Given changes in land usage and the improvement of peasant economies, we envisage a profound mutation in the rural landscape of Azuay.Notwithstanding, in lieu of a true model of territorial rural develo
