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 blocks of AO LDI are discussed: AO modulator, photodetector device (FDD) and frequency generator.The features of

Primary school supports early detection of psychological resources and potential disorders in students, because of the massive incidence and influence for the next life of bullying or peer victimization.It is also important for school to provide early intervention.The aim of the study was to develop a concept of psychological resources to adjust ad

The soil management adopted in vineyard inter-rows has a great influence on soil hydraulic properties, and, consequently, on runoff at the field scale.Conventional management with tillage is adopted by vine-growers to improve the soil water recharge during winter.Nevertheless, this practice is known to increase runoff and soil erosion in steep area

This case study offers insights into assessing tomato value chain to improving rural livelihoods of marginal and vulnerable groups in rural Punjab, Pakistan.This research is based on qualitative data collected through Focused Group Discussions (FGDs) in two pilot villages of district Muzaffargarh with men and women farmers separately.The research a
