Abstract Crack is a form of defect that mainly seen in any types building including residential buildings. Building crack-free unrealistic as the crack cannot be fully prevented during construction process. However, simply taken only visually unattractive, it also having major effect on structure safety. This because does not pose direct threat to safety but encourage certain behaviours can lea...

This research was aimed to study the impact of modern technologies represented by (High-productivity improved seeds, fertilizer leaves, Atlantis pesticide) on increasing production both quantitatively and qualitatively. The importance comes from take a set programs use some in order increase productivity donum for purpose vertical per unit area. problem low rate wheat crop Iraq compared global ...

Quality of Service (QoS) is the ability to guarantee a certain level of performance to a data flow ie., guaranteeing required bit rate, delay, etc. IEEE 802.11 a/b/g networks do not provide QoS differentiation among multimedia traffic. QoS provisioning is one of the essential features in IEEE 802.11e. It uses Enhanced Distributed Channel Access (EDCA) which is a contention-based channel access ...

In recent years it has become more and more difficult to distinguish between metaethical cognitivism and non-cognitivism. (Dreier 2004; van Roojen 2004) The distinction most often used to separate the two camps, until recently at least, was their position on the meaningfulness of moral statements and the applicability of truth-predicates to those statements. Cognitivists are said to hold that m...

This study establishes the sequence of myelination in a population of autopsied infants from birth through the second postnatal year. Myelination was assessed in 62 precisely defined central nervous system (CNS) sites of 162 infants with diverse diseases who were autopsied from 1972 to 1984 at Children's Hospital, Boston. The degree of myelination was graded on an ordinal scale of 0-4 using the...

Language, Truth and Logic added expressivism to the inventory of substantive positions in meta-ethics, and the recent defences of versions of it by Simon Blackburn and Allan Gibbard have enhanced its status as a major position. 1 Ayer presented the doctrine as an improvement on subjectivism – that is, on the doctrine that ethical sentences serve to report attitudes of approval and disapproval –...

In this paper, a simple but accurate modeling method for obtaining analytical solutions for the fundamental characteristics of electroosmotic ow through rectangular pumping channels without the Debye–Hückel approximation is presented. The Poisson–Boltzmann equation without the ebye–Hückel approximation for the electric potential distribution and the momentum equation for the velocity profile ar...

The effect of a cloud layer on top-of-atmosphere (TOA) aerosol radiative forcing is examined by means of a one-dimensional vertical column simulation. To span the range between nonabsorbing and strongly absorbing particles, (NH4)2SO4 and soot aerosols are considered individually and in internal and external mixtures. For a cloud layer embedded within an aerosol layer it is shown that direct aer...
