Laboratory flume experiments were conducted to quantify the effects of soil characteristics on critical shear stress low fines content samples collected from Montauk shores in New York. The soils reconstituted at five different contents, ranging between 0 and 20%. These mixtures composed two initial water dry optimum moistures, relative densities, one moderate dense other dense. strength indice...

Studies of matrix in primitive chondrites provide our only detailed information about the fine fraction (diameter <2 μm) of solids in the solar nebula. A minor fraction of the fines, the presolar grains, offers information about the kinds of materials present in the molecular cloud that spawned the Solar System. Although some researchers have argued that chondritic matrix is relatively unaltere...

This paper examines the use of tines and imprisonment to deter individuals from engaging in harmful activities. These sanctions are analyzed separately as well as together, first for identical risk-neutral individuals and then for two groups of risk-neutral individuals who differ by wealth. When fines are used alone and individuals are identical, the optimal tine and probability of apprehension...

New Hugoniot and release adiabat data for 1.8 g/cm3 lunar fines (sample, 70051) in the N 2 to 70 kbar range demonstrate that upon shock compression intrinsic crystal density (. 3.1 g/cm3) is achieved under shock stress of 15 to 20 kbar. Release adiabat determinatioc;s indicate that measurable irreversible compaction occurs upon achieving shock pressures above . k kbar. For shocks in the r y 7 t...

A company produces 1000 metal cylinders a day for 10 days. The government Safety Authority will take a random sample of cylinders, take a random sample of locations within each of these cylinders, and test for percentage Nickel (Ni) and percentage Chromium (Cr). For each sample in which the percentages are outside some intervals, they fine the company e1,000,000. If the proportion of percentage...

The stirred wet milling of aluminum-doped TiO 2 was considered. At speeds 2500–6000 rpm, the pH i.e.p. shifted from 5.7 to ~8, while at 8000 rpm shift in smaller. Milling reduced performance attributed a change predominant mechanism. XPS revealed an approximate linear correlation between relative surface alumina content (at.%) and particle specific area, with shifting corresponding alumina. low...

In earthquake engineering practice, the liquefaction potential of soils is commonly evaluated through simplified procedures. These approaches are suitable for sands with very low to no fines content, which have been traditionally thought be only liquefiable materials. However, field observations and experimental research extensively demonstrated that plasticity silty can also highly liquefiable...

We use cryo-scanning electron microscopy to investigate capillary dominated fluid penetration into a range of papers including unfilled kraft and TMP laboratory sheets, PCC and talc-filled kraft papers with variable filler loadings, laboratory sheets with variable fines contents and a range of papers with differing degrees of sizing. We find that in all unsized samples the penetration of the we...

A numerical simulation is conducted to investigate movement of iron ore fines by ship's rolling motion under saturated condition using the microscopic fluid coupling scheme devised in Discrete Element Method. The solves pore water pressure particle assemblies change void spaces and flows between them. Updated applied related particles around spaces. result shows liquefaction, that is, increases...
