The dynamic stability of out-of-plane masonry walls can be assessed through non-linear analysis (rocking analysis), accounting for transverse walls, horizontal diaphragms and tie-rods. Steel tie-rods are widely spread in historical constructions to prevent dangerous overturning mechanisms simulated by proper elasto-plastic models. Conventionally, design guidelines suggest intensity-based assess...

A novel method we refer to as the tie-line field (TLF) method has been developed to globally determine the tie lines of any three-component two-phase coexistence region by fitting electron-spin resonance (ESR) spectra obtained from compositions on the coexistence curve and within the coexistence region. The TLF method is illustrated by applying it to the liquid-ordered (Lo) and liquid-disordere...

Case 1 A 6 year old boy presented after his older brother had put a non-releasing garden tie around his neck during unsupervised play in the garden. He was unable to release the tie and in his attempt to do so, pulled it tighter. Fortunately, his grandmother was quick to respond and cut the tie oV with kitchen scissors. On examination, he had petechiae over his face but neither neck swelling or...

Background: Wearing a neck-tie is necessary for bankers and office workers as per requirement of their job. It to know about the impact regular tie-wearing. Objective: To find out association neck pain in tie wearing non-tie computer users. Methodology: was comparative cross sectional survey, conducted different banks offices Lahore, sample size 200. Group A: consists 100 regularly tie-wearing ...

In areas with rapidly changing loads of large magnitude, utility companies often experience large deviations in frequency and area control error. Inadvertent tie-line power flow also occurs. The purpose of this research is to examine the effects a large scale energy storage device has on the system response to a rapidly changing load. Two control areas connected by a tie-line are modelled and s...

BACKGROUND Angiogenesis is a very essential process in tumor biology. Vascular endothelial growth factor (VEGF), angiopoietin and its receptor (TIE-2) are very important mediators for angiogenesis. In this trial, we aimed to analyze the role of these mediators on chemotherapy response and survival. PATIENTS AND METHODS Forty four cancer patients and 22 healthy controls were included in the st...

Compositions with tie lines between the and ( ; ) phases in a ternary Re-Cr-Ni system were investigated by heat treating various ternary Re-Cr-Ni alloys at 1573K in vacuum for up to 2000 h. The microstructures of the Re-containing alloys that had been water quenched after various heat treatment for times were observed and their concentration profiles for Re, Cr, and Ni were measured using an el...

The objectives of load frequency control (LFC) are to minimize the transient deviations in these variables (area frequency and tie-line power interchange) and to ensure their steady state errors to be zeros. Since the tieline interfaces give rise to weakly coupled terms between areas, the large-scale power system can be decentralized into small subsystems through treating tie-line signals as di...

Organizations increasingly rely on group-based organizational structures to manage uncertain environments. However, at the group level there is still a limited understanding of how boundary-spanning activities should be managed to increase group performance. In this paper, we propose “out-grouptie centralization” as a concept that refers to the variation in the group members’ network ties to ot...
