The purpose of the hot rolling mill is to make a preheated steel block thinner and longer, see Figure 1. This is done by pulling the plate through two parallel rolls mounted in the rolling mill. Due to the large forces obtained in hot rolling, the elastic de ection of the rolling mill is of the same order of magnitude as the plate thickness. Variations in the rolling force caused by variations ...

The paper discusses the numerical optimization design of anchoring end of prestressed cable at some hydropower station. There are two types of designing for the anchoring end, namely using square thick steel anchor bearing plate or using the roundtower anchor bearing plate. By the numerical calculation, the anchoring end using the round-tower anchor bearing plate can match the space and mechani...

Lithium titanate (Li2TiO3) is candidate tritium breeder of the fusion blanket systems. The small pebbles Li2TiO3 are packed in box. coolant tubes made RAFM steel F82H (Fe-8Cr-2W-0.1C) installed box and their oscillation possibly induced by flow. fretting corrosion then caused reciprocating slip on tube wall. purpose present study to investigate fundamental behaviors between pebble plate. or Al2...

This study aims to analyze the deflection behavior of sheet pile through experimental testing and numerical analysis using Finite Element Method (FEM). The Laboratorium scale test on a Tub with length 1500 mm, width 600 height Steel Plate 3.2 mm dimensions 1400 x 590 was used as model wall. subgrade material is clay soil embankment in form Sirtu which passes No. sieve. 40. Physical mechanical g...

This paper proposes, for low buildings, an integrated wall structure of a brick-stem-insulating layer, which plays a major part in both heat preservation and force bearing. The research team has tested the thermal performance of the structure, the results of which are satisfying. To further study the force-bearing performance, the paper carries out compressive tests of specimens of different st...

The need to maintain stability of the chest wall with stainless steel strips in three unusual sets of circumstances is explained. That 'flail' chest is not synonymous with 'stove-in' chest is made clear. Some of the problems which relate to the maintenance of chest wall stability were discussed in a previous paper (le Roux, 1964). In respect of restoration of rigidity of the chest wall after re...

The medial septal region and the hippocampus are connected reciprocally via GABAergic neurons, but the physiological role of this loop is still not well understood. In an attempt to reveal the physiological effects of the hippocamposeptal GABAergic projection, we cross-correlated hippocampal sharp wave (SPW) ripples or theta activity and extracellular units recorded in the medial septum and dia...

Mechanisms of place cell replay occurring during sharp-wave ripples (SPW-Rs) remain obscure due to the fact that ripples in vitro depend on non-synaptic mechanisms, presumably via axo-axonal gap junctions between pyramidal cells. We suggest a model of in vivo SPW-Rs in which synaptic excitatory post-synaptic potentials (EPSPs) control the axonal spiking of cells in SPW-Rs: ripple activity remai...

This paper presents an ongoing research project on the behavior and design of “hybrid” precast concrete wall structures for use in seismic regions. Hybrid precast walls utilize a combination of mild (e.g., Grade 60) steel and high-strength unbonded post-tensioning (PT) steel for flexural resistance across horizontal joints. The mild steel reinforcement is designed to yield in tension and compre...
