We review Maxwell’s multipole vectors, and elucidate some of their mathematical properties, with emphasis on the application of this tool to the cosmic microwave background (CMB). In particular, for a completely random function on the sphere (corresponding to the statistically isotropic Gaussian model of the CMB), we derive the full probability density function of the multipole vectors. This fu...

background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...

Cancellous bone microstructure is an important determinant of the mechanical integrity of vertebrae. The numerous microstructural parameters that have been studied extensively are generally represented as a single value obtained as an average over a sample. The range of the intra-sample variability of cancellous microstructure and its effect on the mechanical properties of bone are less well-un...

A note may be added here as to certain findings not usually recorded in "official" descriptions of examinations of the cerebro-spinal fluid. In the centrifugalised deposits of lumbarpuncture specimens, I have not infrequently encountered squamous cells from the skin-surface, together with their accompanying staphylococci, etc., and occasionally even a little cylindrical fragment of skin punched...

In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag on mechanical characteristics for stabilized cement and un-stabilized soil. Dozens of specimens were prepared at four percentages of cement (i.e. 0%, 2%, 4% and 6%) and five percentages of copper slag (i.e. 0%, 5%, 10%, 15% and 20%) by weight of dry soil. The samples compacted into a cylind...

by drawing blood through a heparin lock, patients can be protected from skin damages duo to repeated needle sticks. in addition, this procedure can assist to gain more precise results in laboratory test and to prevent further complications. probably, you have ever used a heparin lock in order to infusion of medicines but, it is possible that you never use of that for blood sampling. both two pr...

Abstract In the present study, effect of cone angle tool pin on mechanical properties and microhardness aluminum alloy AA6061-T6 specimens is investigated for three processes SFSW, symmetric DFSW, asymmetric DFSW. each mentioned welding processes, tools with 5 different conical angles 0, 5, 10, 15, 20° are used. these final welded joint have been enhanced noticeably compared to simple cylindric...

The effect of shear stress on the dynamic failure ceramic materials is not sufficiently investigated in published literature. With use a bespoke split Hopkinson pressure bar, this paper presents an effort to investigate compressive response Macor, model material with zero porosity and light weight characteristics. A cone specimen cylindrical specimens varying inclined angles are used introduce ...

In the field of materials engineering, various types advanced have been found. This must also be accompanied by technological advances in production process. Centrifugal casting is an effective method for cylindrical objects such as pipes and pressure vessels. this research, a centrifugal machine designed made. The design process follows steps proposed Pahl Beitz, starting from requirements ide...

Abstract Bamboo plants are one of the natural materials that often seen growing and quite fast; has been extensively researched for use as an alternative to steel reinforcement in concrete construction. is not only more accessible, it also cost effective beneficial environment. This study examines bonding strength bamboo concrete. Buluhpring from Gowa area which dried checked quality material u...
