A micro strip-fed printed bow-tie antenna is presented inorder to achieve wide bandwidth, high gain, and size reduction. A comparisonbetween the bow-tie and the quasi-Yagi (dipole and director)antennas shows that the bow-tie antenna has a wider bandwidth, highergain, lower front-to-back ratio, lower crosspolarization level, andsmaller size. Two-element arrays are designed and their characterist...

including baseline length and tilt. Successful implementation Ground tie points have been used to improve the accuracy of a DEM derived from interferometric SAR (I~SAR) data. The number of tie points required for ensuring certain accuracy of the I~SAR-derived DEM was investigated in this study in two ways. One is the least-squares estimate of the corrections to a DEM using tie points, and the o...

Cluster supply chain (CSC) is a special kind of enterprise network with double feature of cluster and supply chain and is an important channel for enterprises close to the knowledge, resources, markets, and technologies. Cluster supply chain has special network structure and network relational which are different from general cluster and supply chain. In a particular industry cluster region, al...

The study reported here examines characteristics of weak-tie support network preference among members of health-related computer-mediated support groups. Drawing on weak-tie support network theory and socioemotional selectivity theory, participants’ age and health condition were assessed as predictors of weak ties support network preference. Relationships between the dimensions of weak-tie supp...

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 ...

As a spread phenomenon, tacit knowledge integration has been attracting more attention because of the embeddedness in social activities and interactions. Our works, as a complement to previous research, investigate tacit knowledge integration based on social networks from transactive memory systems (TMS) perspective. We focus on ties dimension (expressive tie, instrumental tie, and tie strength...

Activation of endothelial cells, important in processes such as angiogenesis, is regulated by cell surface receptors, including those in the tyrosine kinase (RTK) family. Receptor activity, in turn, can be modulated by phosphorylation, turnover, or proteolytic release of a soluble extracellular domain. Previously, we demonstrated that release of soluble tie-1 receptor from endothelial cells by ...

Consensus does not exist on the level of arterial ligation in rectal cancer surgery. From oncologic considerations, many surgeons apply high tie arterial ligation (level of inferior mesenteric artery). Other strategies include ligation at the level of the superior rectal artery, just caudally to the origin of the left colic artery (low tie), and ligation at a level without any intraoperative de...
