Paragonite has been found in two chloritoid-chlorite-mica schists from the Dalradian, north of Stonehaven. The principal bulk-chemical constraints on the occurrence of this mineral within the chloritoid zone appear to be the ratios of soda to potash and the A1203 contents of the rock. The composition of paragonite coexisting with muscovite indicates a crystallization temperature of 550 ~ for ro...

Mineral Aerosol dusts have complex non spherical shapes and varying composition. This is utilizes data on morphology (size and shape) and composition of dust particles to determine the extent to which the optical properties of real particles differ from those of spheres. In morphology we find the aspect ratio, circularity factor and radius than discuss the size and shape of the aerosol dust par...

BACKGROUND Currently debate still exists about the effects of thyroid hormone therapy on skeletal integrity, that is the safety of levothyroxine use with respect to bone mineral density. OBJECTIVE A systematic review of the effects of TSH-suppressive and replacement levothyroxine therapy on bone mineral density evaluated main causes of conflicting results and its implications for clinical pra...

Hyperspectral remote-sensing in the reflected infrared and thermal infrared regions offers a unique and efficient alternative for mineral mapping, as most minerals exhibit spectral features in these regions, mainly in the shortwave and longwave infrared. Airborne hyperspectral data in both spectral regions, acquired with the AisaFENIX and AisaOWL (Specim) sensors over Makhtesh Ramon in Israel, ...

INTRODUCTION The surface method of measuring lower thoracic and lumbar spine motion with Fastrak ® was examined for validity. There is an increasing awareness of the health risks of exposure to radiation associated with repeated radiographic assessment of spinal curvature and spinal movements. As a skin-surface measurement device, Fastrak ® was employed to study the effect of low bone mineral d...

Osteoporosis is a disease of bones that leads to an increased risk of fracture. In osteoporosis, the bone mineral density (BMD) is reduced. Globally osteoporosis constitutes a public health problem. Researchers have been curious about the true estimate of osteoporosis prevalence in the Kingdom of Saudi Arabia. The current study was designed to assess the extent of knowledge attitude and practic...

Interest has risen among utilities in using natural ester (NE) insulating oils in transformers as a substitute for conventional mineral oil. However, present understanding on aging behaviour of NE-paper composite insulation system and knowledge on application of existing condition monitoring tools for NE-based insulation are inadequate. This limits the cost effective and reliable field applicat...

This paper presents the methods and techniques used in the recently developed JKMRC/FEI Mineral Liberation Analyser (MLA). The MLA system consists of a specially developed software package and a standard modern SEM fitted with an energy dispersive spectrum (EDS) analyser. The on-line program of the MLA software package controls the SEM, captures sample images, performs necessary image analysis ...

The aim of this work was to study the biodegradation of different types of automotive lubricant oils adapted to the aqueous medium using a base inoculum and an aqueous inoculum. Four treatments were carried out in two consecutive and similar experiments: T1 (control); T2 (half-synthetic oil); T3 (mineral oil); T4 (used oil). The results showed the following decreasing order of CO2 production in...
