Chapter 2: Physical Properties and Principles

The hydraulic head h must be measured with a tensiometer The hydraulic conductivity K and the moisture content θ are both functions of the pressure head ψ In short for saturated flow ψ 0 θ = n and K = K 0 for unsaturated flow ψ 0 θ = θ(ψ) and K = K(ψ) The capillary fringe fits into neither of the groupings above

Odessa oil and the welding arc

Mosman said he's also seeing more self-shielded flux-cored welding in the field but stick welding using the 6010 or 7018 electrode is the perennial standby "I do CWI work and most of the API testing I do is still 5P+ downhill or 7010 downhill welding on the big 12-inch pipe

Materials

The importance of surface roughness and its non-destructive examination has often been emphasised in structural rehabilitation The presented innovative procedure enables the estimation of concrete-to-concrete strength based on a combination of low-cost area-limited tests and geostatistical methods The new method removes the shortcomings

Attached and Unattached Bacterial Communities in a

Compositional differences between attached and unattached (suspended in associated aqueous phase) microbial communities may develop due to selective advantages conferred on some populations by attachment to environmental surfaces () Attachment of individual bacterial cells (of a single population) has frequently been associated with substantial changes in cell physiology although the

A discussion on the intended use and limitations should be included if a report is prepared 5B 4 We have had much discussion recently about the definition and use of RQD and we would like to relay our feelings on the following three areas (1) As we understand it RQD is calculated counting only those pieces of drill core greater than 4

Drought‐induced defoliation and long periods of

Drought‐induced defoliation has recently been associated with the depletion of carbon reserves and increased mortality risk in Scots pine (Pinus sylvestris ) We hypothesize that defoliated individuals are more sensitive to drought implying that potentially higher gas exchange (per unit of leaf area) during wet periods may not compensate for their reduced photosynthetic area

Linking fine root traits to maximum potential growth

Discussion Patterns of root morphology architecture and chemistry among the fine roots of fast‐ and slow‐growing tree species in north‐eastern temperate forests suggest that plants with high potential growth rates constructed their finest orders of roots for quick exploration of soil resources short life span and rapid decomposition

Experimental Investigation on Propagation Behavior

Refracturing is an effective technology for reinstituting a percolation path and improving the fracture conductivity in coal measure strata Hydraulic fracture (HF) propagation is complicated due to the presence of cleats and stress change caused by pore pressure changes Many scholars have studied HF propagation in the initial fracturing of coal but the refracturing in coal seams is rarely

Ancient Roman syntheses of Al-tobermorite in a 2000-year-old concrete block submerged in the Bay of Pozzuoli (Baianus Sinus) near Naples have unique aluminum-rich and silica-poor compositions relative to hydrothermal geological occurrences In relict lime clasts the crystals have calcium contents that are similar to ideal tobermorite 33 to 35 wt% but the low-silica contents 39 to 40 wt
