Other articles where In situ measurement is discussed: atmosphere: Measurement systems: atmosphere are of two types—in situ measurements and remote sensing observations. In situ measurements require that the instrumentation be located directly at the point of interest and in contact with the subject of interest. In contrast, remote sensors are located some distance away from the . Here, we leverage synchrotron X-ray diffraction, carried out in situ during calcination and decomposition of LNO at high temperature, to reveal the evolution of precursor materials during solid-state synthesis. We evaluate the effect of pre-annealing the hydroxide precursors’ mixture at low temperature, prior to the actual calcination at °C.

SmartRock™ is the world’s #1 wireless sensor for monitoring the curing and hardening of concrete. Unlike time-consuming and error-prone break tests, or cumbersome wired sensors, Giatec’s patented SmartRock sensor is fully embedded and secured on the rebar, making it completely maintenance and hassle-free. Temperature data is collected, and the strength of your in-place concrete is.

This value is significantly lower than that typically assumed for.

In Situ Rock Temperature. Stress Investigations in Rock Quarries. Authors Hooker-VE; Duvall-WI Source NTIS: PB pages Link NIOSHTIC No. Abstract Near-surface temperature measurements in two granite quarries show that diurnal temperature variations are significant to a depth of 1 or 2 feet, and annual temperature variations.

Price New from Used from Library Binding, January 1, Author: Charles Fairhurst. Abstract. This chapter first briefly describes in situ rock stresses and the strategy for estimating them. Then the various methods for making preliminary estimation of in situ rock stresses are presented, including the World Stress Map, the empirical correlations between vertical and horizontal stresses and depth, and the different analytical models.

When a pore fluid is relatively cold (Ttemperatures are typical for the upper 3 km of the crust), brine-filled cracks in a rock behave as "stiff" inclusions, a, : Irina Artemieva. the rock mass, it must be recognized that an in situ pre-existing state of stress already exists in the rock.

Use this durable. Rock strength and porosity have good correlations for various rocks, and porosity can be obtained from lab tests or from density and sonic logs.

In the following equations, the rock strength UCS is in MPa and porosity is in percent (%). For shales in the North Sea (geologically young and weak shales, mostly high-porosity Tertiary shales), Horsrud () proposed the following correlations for. (temperature, viscosity, density).

Intrinsic permeability, k (cm2 or darcys) - permeability defined by the property of the material • Rock behavior is more complex than ideal materials • Common method of testing rock behavior is the unconfined compression test In cancer/oncology: in situ means that malignant cells are present as a tumor but have not metastasized, or invaded beyond the layer or tissue type where it arose.

This can happen anywhere in the body, such as the skin, breast tissue, or lung. For example, a cancer of epithelial origin with such features is called carcinoma in situ, and is defined as not having invaded beyond the basement.

The estimated in situ temperatures from all three tools define a linear gradient of C/m in the upper m (Fig. F52), yielding a conductive heat flow of ~ mW/m 2 at Site This value is generally consistent with, but slightly higher than, prior determinations of high heat flow near the toe of the Nankai accretionary prism in the.

An experimental air convection embankment (ACE) was constructed in Beiluhe on the Qinghai-Tibet Plateau during –, using coarse (5–8 and 40–50 cm), poorly graded crushed rock fill material on the slope of embankment with thick ground ice permafrost foundation, which should be called the air convection embankment with crushed rock slope protection (ACE–CRSP).

The paper describes the performance, observations and interpretation of a large-scale in situ heating test that simulates a disposal concept for heat-emitting, high-level nuclear waste. In the expe. Geotechnical Manual. Geotechnical Manual.Maturity is a non-destructive approach to testing concrete that allows you to estimate the early-age and compressive strength of in-place concrete in real-time.

Adopting the maturity approach in your jobsite eliminates the need for concrete cylinder break tests, allowing you to greatly optimize your schedule. Rock disintegration without any change in chemical constituents of rocks takes place. Factors such as temperature, moisture, pressure cause physical break-up of rocks.

It takes place in hot dry and cold areas due to rapid temperature changes. Rocks are affected to great depths. Its agents are temp erature and moisture. Chemical Weathering.
