The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

Heavy high viscosity oils, transformer oils, and very light low viscosity oils have been used in a Norwegian company in the impregnation, sheathing, and installation of paper insulated cables. The aim of the present study was to determine exposures to oils and other chemicals at these workplaces from 1920 to 1979. Oil mist was sampled on glass fibre or membrane filters and analysed by infrared ...

in this paper robust pid control of fully-constrained cable driven parallel manipulators with elastic cables is studied in detail. in dynamic analysis, it is assumed that the dominant dynamics of cable can be approximated by linear axial spring. to develop the idea of control for cable robots with elastic cables, a robust pid control for cable driven robots with ideal rigid cables is firstly de...

We report the design and the electrical and microfluidic characterization of a device that improves signal strength and increases the detection levels in microfluidic impedance cytometry. Low-conductivity aqueous and two-phase dielectric sheathing allows the use of wider, more easily fabricated channels, increases the precision of celland particle-size measurements, and decreases the smallest d...

Creep response of a full-scale floor system fabricated with composite wood I-joists and oriented strand board (OSB sheathing) was measured for 280 days at sustained uniform loads of 20 psf (0.96 kPa). Creep responses of bare I-joists and 3-joist T-beams with OSB sheathing (glued and unglued tongue and groove sheathing joints) were measured under similar load levels and duration. The creep defle...

Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...

In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...

We present the lead isotopic composition of ceramic fragments from Kyrenia shipwreck (Cyprus), selected three chemical groups related to Rhodes and Alimos regions (Greece). Fragments sheathing covering ship’s hull biogenic material formed on some sherds, were analyzed along with sherds source areas for comparison. The objective this paper was evaluate impact seawater environment signature ceram...

INTRODUCTION Frosted branch angiitis usually occurs in children and presents with severe sheathing of all retinal vessels mimicking the appearance of frosted branches of a tree. OBJECTIVE To report a case of frosted branch angiitis in a pregnant lady. CASE We, hereby, report a case of a 24-year-old pregnant female who presented to us with the complaints of sudden diminution of vision in the...
