Soil investigation is the main key in starting construction. Standard Penetration Test (SPT) and Cone (CPT) are field tests often used to estimate soil parameters for foundation design purposes. The SPT value (N-SPT) shows a correlation between CPT other parameters. At present, there have been many conventional correlations examining these correlations, but nonlinear nature of due very complex ...

PURPOSE The purpose of this study was to describe a previously unreported manifestation of the optical Stiles-Crawford effect (oSCE) in normal eyes. METHODS In a cohort of 50 normal subjects, the directional reflectance of cones in the retinal periphery was explored by flood-illuminated adaptive optics (FIAO) and optical coherence tomography (OCT). RESULTS In 32 eyes (64%), off-axis FIAO im...

Abstract Land subsidence in Pekalongan city has affected almost the entire municipality for at least ten years. occurred all areas 2-12 cm/year rates. The direct and indirect environmental impacts of land are enormous. We aim to map evaluate severity with subsurface condition area. employed site investigation using resistivity CPTu soundings representative sites reveal soils survey impacts. Res...

Ultrathin topological insulator nanostructures, in which coupling between top and bottom surface states takes place, are of great intellectual and practical importance. Due to the weak van der Waals interaction between adjacent quintuple layers (QLs), the layered bismuth selenide (Bi(2)Se(3)), a single Dirac-cone topological insulator with a large bulk gap, can be exfoliated down to a few QLs. ...

Silt sediments are frequently encountered in the coastal areas of the North Sea. Evaluation of the silt behaviour must ideally rely on in-situ tests, in particular the piezocone test. However, interpretation of piezocone data in silt sediments is problematic and derived parameters can seem to differ significantly from those obtained by investigating intact samples in the triaxial apparatus. Use...

Nanogenerators were first demonstrated by deflecting aligned ZnO nanowires using a conductive atomic force microscopy (AFM) tip. The output of a nanogenerator is affected by three parameters: tip normal force, tip scanning speed, and tip abrasion. In this work, systematic experimental studies have been carried out to examine the combined effects of these three parameters on the output, using st...

A nose cone is the conically shaped tip part of a missile, bomb or aircraft, used to regulate behavior oncoming airflow and minimize drag. In this study, effects different designs on trajectory impact angle smart fire extinguishing ammunition were investigated. For purpose, three types with profiles designed: spherically blunted conic cone, tangent ogive truncated cone. virtual wind tunnel was ...

The aim of this laboratory-based study was to investigate the effects of different combinations of tip and torque upon friction between an orthodontic bracket and archwire using a specially made jig. Victory Twin Series upper premolar brackets (3M Unitek) were mounted on a jig, which allowed tip and torque values in the slot to be varied without altering the centre of rotation. The jig was moun...

Bamboos are arborescent monocotyledons that have no secondary growth, but can continually produce conduits with diameters appropriate to the current size of plant. Here, we studied bamboo hydraulic architecture address mechanisms involved in compensating for increase resistance during ontogeny. We measured weighted vessel (Dh) at different distances from apex along stem Bambusa textilis. The co...
