The prologue of new High Voltage (HV) transmission mains into the community necessitates earthing design to ensure safety compliance of the system. Concrete poles are widely used within HV transmission mains; many retired transmission mains with timber poles are being replaced with concrete ones, green transmission mains are deploying concrete poles. The earthing arrangement of the concrete pol...

This investigation determined the gluability of weathered, out-of-service southern yellow pine (SYP) (Pinus spp.) utility poles. Three types of adhesives were used: resorcinol-phenol formaldehyde (RPF), polyvinyl acetate (PVA), and casein. The poles consisted of two service duration groups: 5 and 25 years. Longer weathering caused greater reduction in creosote content, especially in the outer a...

Standard myoelectric control systems use carefully placed bipolar electrode pairs to provide independent myoelectric signals (MESs) for prosthesis control. Because myoelectric pattern recognition systems do not require isolated MESs, the two electrode poles used for each MES channel may be placed longitudinally along individual muscles or transversely across multiple muscles. In addition, each ...

Immunolocalization of auxin using a new specific antibody revealed, besides the expected diffuse cytoplasmic signal, enrichments of auxin at end-poles (cross-walls), within endosomes and within nuclei of those root apex cells which accumulate abundant F-actin at their end-poles. In Brefeldin A (BFA) treated roots, a strong auxin signal was scored within BFA-induced compartments of cells having ...

Woodc:n poles are popular structural elements currently used by Manitoba Hydro for distribution lines and transmission towers. In recent years, a considerable number of such poles have failed duc to heavy build-up of ice on the lines. These failures may be attributed to the accuracy or reliability of the design methods and/or to the lack of adequate experimental information to evaluate the crit...

How is motion information that has been obtained through multiple viewing apertures integrated to form a global motion percept? We investigated the mechanisms of motion integration across apertures in two hemifields by presenting gratings through two rectangles (that form the dual barber poles) and recording the perceived direction of motion by human observers. To this end, we presented dual ba...

This paper studies the singularities of Cullen-regular functions of one quaternionic variable, as defined in [7]. The quaternionic Laurent series prove to be Cullen-regular. The singularities of Cullenregular functions are thus classified as removable, essential or poles. The quaternionic analogues of meromorphic complex functions, called semiregular functions, turn out to be quotients of Culle...

Project Description: Background & Purpose Exploring the Poles is a Barnard College First-Year Seminar. “First-Year Seminars focus on critical reading, writing, and speaking skills in the context of intellectual exploration and social bonding in a shared first-year experience.” They comprise introductory courses taught by faculty from different disciplines. Exploring the Poles is classified acco...

BACKGROUND Chromosomes must biorient on the mitotic spindle, with the two sisters attached to opposite spindle poles. The spindle checkpoint detects unattached chromosomes and monitors biorientation by detecting the lack of tension between two sisters attached to the same pole. After the spindle has been depolymerized and allowed to reform, budding yeast sgo1 mutants fail to biorient their sist...

Globalization is recognized as consciously carrying two sides of values ​​for human life, namely good ​​and bad values. These value penetrate into all aspects the order life. Consequently, globalization raises many problems that plague inhabitants planet earth today. Among impacts are emergence contemporary issues related to religion well challenges for Islamic da'wah, such as: religious plural...
