B. C. O’Kelly, Trinity College Dublin The authors rightly state that the strength gain ratio over the plastic range (R 1⁄4 cu(PL)=cu(LL)) is often about 100 for many soils, although there is no theoretical basis for a universal value of 100, and that other researchers have postulated cu(PL) 170 kPa and R up to as high as 170. The LL, PL and R values largely depend on the grading and mineralogy,...

Geospatial models for predicting soil liquefaction infer subsurface traits via satellite remote sensing and mapped information, rather than directly measure them with tests. Field tests of such have demonstrated both promising potential severe shortcomings. Informed by these tests, this paper develops geospatial that are driven algorithmic learning but pinned to a physical framework, thereby be...

A spark plug fuel injector (SPFI), which is a combination of a fuel injector and a spark plug was developed with the aim to convert any gasoline port injection spark ignition engine to gaseous fuel direct injection (Mohamad in Development of a spark plug fuel injector for direct injection of methane in spark ignition engine. PhD thesis, Cranfield University, 2006). A direct fuel injector is com...

AIM To compare the apical sealing in mesio-buccal canals of extracted molars obturated with low-temperature thermoplasticized gutta-percha or cold lateral condensation techniques using a .06 or a .02 mm/mm tapered gutta-percha master cone. The secondary aim was to evaluate the depth of spreader penetration in root canals using a .06 or a .02 mm/mm tapered gutta-percha master cone. METHODOLOGY...

 Background and Objective: The endodontic management of immature teeth with wide open apices has always posed particular problems. A number of canal preparation and filling techniques have been described such as apexification, surgery and retrograde filling, customized-cone, and apical plug. The purpose of this study was to compare the sectional technique microleakage in open apices with ...

for a determination of soil characteristics one should have access to instruments that can measure these characteristics, including: soil penetration resistance with high accuracy. one of the accurate instruments commonly employed in soil penetration determinations is cone penetrometer. this apparatus, by measuring soil cone index at different soil depths can provide useful about information ab...

The size of a nanomedicine strongly correlates with its biodistribution, tissue penetration, and cell uptake. However, there is limited understanding how the size of nanomedicine impacts the overall antitumor efficacy. We designed and synthesized camptothecin-silica nanoconjugates (Cpt-NCs) with monodisperse particle sizes of 50 and 200 nm, two representative sizes commonly used in drug deliver...
