Abstract:
Abstract The International Organization for Standardization (ISO) 15189:2012 standard aims to improve quality in medical laboratories through standardization of all key elements in the total testing process, including the pre-analytical phase. It is hence essential that accreditation bodies, assessing laboratories against ISO15189:2012, pay sufficient attention to auditing pre-analytical activities. However, there are significant differences in how technical auditors interpret the pre-analytical requirements described in ISO15189:2012. In this consensus document, the European Federation of Cli

AbstractDevelopment of a chromatographic method in bioanalysis is a challenging and complex procedure with many pitfalls and often unexpected reversals that can require several months to accomplish. Even an experienced analytical team must contend many limitations mainly in connection with the strict requirements imposed on current clinical research. These restrictions typically persist throughout the whole development process, from clinical trial assignment, across optimization of extraction of biological materials and chromatographic separation, to validation and data interpretation.

The aim of this paper is to point out the importance of proper pre-analytical preparation of the sample in order to reduce the number of errors in the laboratory with a special emphasis on hemolysis. In recent years, the lab has become more efficient in terms of faster results, more precise, faster and more precise controls, all due to automation, but it needs to be cautious as errors continue to occur. The largest share of errors occurs in the pre-analytic and post-analytical phase. The erythrocyte hemolysis in vivo or in vitro is one of the most significant errors in the preanalytic phaseThi

Abstract:
Abstract The understanding of how the microstructure influences the mechanical response is an essential pre-requisite for materials tailored to match specific requirements. The aim of this chapter is to further this understanding in the context of Mg-PSZ-TRIP-steel composites on three different scales using a set of methods ranging from phase-field simulations over micromechanics to continuum constitutive modeling. On the microscale, using a Ginzburg-Landau type phase-field model the effects of cooling- and stress-induced martensitic phase transformation in MgO-PSZ is clearly distinguished. Additionally with this method the role of energy barrier in variant selection and the effect of residual stress contributing to the stability of the tetragonal phase are also investigated. On the mesomechanical scale, an analytical 2D model for the martensitic phase transformation and self-accommodation of inclusions within linear elastic materials has been successfully developed. The influences of particle size and geometry, chemical driving force, temperature and surface energy on the $$t \rightarrow m$$ t → m transformation are investigated in a thermostatic approach. On the continuum scale, a continuum material model for transformation plasticity in partially stabilized zirconia ceramics has been developed. Nonlinear hardening behavior, hysteresis and monoclinic phase fraction during a temperature cycle are analyzed. Finally, The mechanical properties of a TRIP steel matrix reinforced by ZrO$$_2$$ 2 particles are analyzed on representative volume elements. Here the mechanical properties of the composite as function of volume fraction of both constituents and the strength of the interface are studied.

Abstract:
The chapter argues that a Laboratory Information Management System (LIMS) is the application of computational technology in laboratory medicine. This is an advanced technology that can support the general work in medical laboratories. The LIMS can also be useful in all steps of the laboratory cycle (pre-, intra-, and post-analytical phases). There are many LIMSs at present, and those LIMSs are used worldwide. The present concern is on the standardization of the existing system. In this context, international collaboration to set the standards is required. In addition, the multidisciplinary approach to add up the advantage and application of the technology is promising. With the more advanced computational and wireless information technology, the next step of LIMS will be big wireless LIMS networks that extend from medical laboratories and wards within the hospital to outside units as well as patient homes. The point-of-care LIMSs are the actual future perspectives.

Abstract:
Usability inspection method (UIM) is the term used for a variety of analytical methods designed to “find” usability problems in an interface design. The basic principle involves analysts inspecting the interface against a set of pre-determined rules, standards or requirements. Analysts inspect the interface and predict potential usability problems based on breaches of these rules. None of the UIMs currently in use are capable of detecting all of the problems associated with an interface. After describing some of the UIMs in use, this article will look at the authors’ work on improving these methods by focusing on the resources analysts bring to an inspection.

Those functions suggest the components that it must have, usually chosen from a pre-defined set. Also, structural elements must be added, based on project and manufacture requirements, so the cable can withstand the environmental conditions of use. All the components must be geometrically arranged and the cross section of the cable must be defined, usually with the help of CAD software. But the structural behavior of the de

To prevent this from occurring, compressor stations are designed with single or dual recycle systems with recycle valves, which are required to open upon ESD. There has been extensive debate and c

Existing finite-element methods for modeling closure stresses from bolt pre-load are not readily adaptable to dynamic analyses. The HAC events are required to occur sequentially per 10CFR71 and thus the evaluation of the cumulative damage is desirable.

The kinematics of the spiral pulley are firstly developed and its geometry is then optimised by employing an energy conversion efficiency function.
