New Research

New research of Lithuanian territory gravity field was started in 2016 with aim to improve accuracy of quasigeoid as well as accuracy of normal heights determined by methods of satellite geodesy. Obtained data could be used in the research of geophysics, geodynamics as well as in performing the precise navigation. Quartz automatic gravimeters Scintrex CG-5 are planned to be used for the survey consisting of 30000 points. Method of gravity measurements was worked out. RMS error of gravity determined with this method does not exceed 60 @Gal. Coordinates and heights of measured points are determined with GNSS using LitPOS network and LIT15G quasigeoid model. RMS error of coordinate determination does not exceed 0,20 m, for normal heights – 0,15 m. Method of gravity anomalies determination and their accuracy estimation was prepared.

Electrode Insertion

Exploratory electrode insertions using a stereotaxic instrument, without passing current, have been made bilaterally in and around the area in the hypothalamus of the rat where electrolytic lesions produce complete aphagia and adipsia. These ‘sham operations’ produce pronounced hypophagia and hypodipsia for 1–2 days. Effect on food intake is large and fairly uniform with all insertions peripheral to these nuclei but increases abruptly in the immediate neighborhood of the nuclei. It is suggested that electrode insertion without passing current may be useful as a finer tool than electrolytic lesions for precise localization of the centers involved.
