abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Primitive arc magmatism and mantle wedge processes are investigated through a petrologic and geochemical study of high-Mg# (Mg/Mg ? Fe [ 0.65) basalts, basaltic andesites and andesites from the Kurile-Kamchatka subduction system. Primitive andesitic samples are from the Shisheisky Complex, a field of Quaternary-age, monogenetic cones located in the Aleutian–Kamchatka junction, north of Shiveluc...
The Nokeh intrusion exposed in the northern Semnan area. The intrusion is composed of monzonite-quartz monzonite and granite-granodiorite and was intruded in the Eocene carbonaceous tuffs, where the country rocks converted to magnetite-skarn. Plagioclase, orthoclase, quartz, biotite, amphibole and clinopyroxene are the constituent minerals of Nokeh intrusion. The study rocks represent granular,...
The ore bodies of Galali and Baba-Ali are two relatively important iron ore deposits in west Iran. These ore deposits are situated in the Sanandaj-Sirjan zone. The deposits are associated with ultramafic, calc-alkaline, carbonatite and other rocks. Macroscopic observations, on the boreholes, show that one of the rare ultramafic rocks (hornblendite) appears in all various horizons parallel to m...
The Nikuyeh district is located south of the Tarom-Hashtjin metallogenic province in Western Alborz. Oligo-Miocene subvolcanic intrusion and Mid-Eocene volcanic rocks with composition of dacite to andesite are main igneous settings associated with Nikuyeh polymetallic epithermal ore mineralization. Igneous phase in the Nikuyeh district are porphyritic granodiorite, monzodiorite, quartz monsonit...
AIMS This trial compares to methods used to find the insulin dose when starting insulin in people with type 2 diabetes in whom maximal tolerated oral hypoglycaemic agents have failed to control glycaemia. One method of initiating insulin (based on height, weight, and fasting blood plasma glucose and insulin resistance) was compared with a conventional method of initiating 10 units of isophane i...
Lokasi studi yang terletak di daerah Ciletuh merupakan bagian dari Unesco Global Geopark dicirikan oleh batuan beku intrusif dan ekstrusif berumur Miosen. Batuan ini tersebar sepanjang pantai sebagian membentuk perbukitan kecil. Tujuan adalah untuk mengkarakterisasi mengetahui petrogenesis ada Cisolok. Metode kegiatan dilakukan menggunakan analisis petrografi, geokimia, XRF ICP-MS. Secara petro...
Long term defence planning is a complex undertaking involving many separate analytical steps and with non-trivial transitions from one step to the next. Many nations struggle with the challenge of establishing analytical rigour, structure and traceability in their defence planning processes. In this paper we will present a tool that has been developed not only to support defence planning, but w...
