Detection of toxic hexavalent chromium in soil, groundwater, industrial effluent, etc., is of significant interest. We demonstrate the electrochemical detection of Cr(VI) using a surface-engineered mesoporous carbon-based material. The mesoporous carbon-based material is obtained by the controlled pyrolysis of a homogenous mixture of Fe and Co complexes of hydrolyzed collagen. The as-synthesized m
John Maynard Keynes was nominated for the Nobel Peace Prize in the 1920s for writing “The Economic Consequences of the Peace”. Yet, despite being highly ranked by the advisor of the Nobel Committee and placed on the shortlist, he did not win. This column brings out previously unused archival material from the Nobel Committee in Oslo to explore why. The Committee tended to withhold the Prize when c
Bifunctional DNA glycosylases employ an active site lysine or the N-terminus to form a Schiff base with an abasic (AP) site base excision repair intermediate. For 8-oxoguanine DNA glycosylase 1 (OGG1), cleaving this reversible structure is the rate-determining step in the initiation of 8-oxoguanine (8-oxoG) repair in DNA. Evolution has led OGG1 to use a product-assisted catalysis approach, where t
With this audio paper, our aim is to explore the connection between sound and democracy. Recognizing the multifaceted nature of this field, we approach it through the notion of care and an empirical analysis of the democratic implications of trying to regulate sound in public spaces. We examine ISO standards as one example of the many attempts to control sound in both public and private spaces. St
In this work, we model the basic mechanisms of the interaction between phase-transformations and plasticity within a one-dimensional constitutive framework. Efficient algorithms are presented, facilitating to solve the underlying evolution equations with high numerical stability at low numerical costs. Furthermore, a family of functions covering physically reasonable classes for the inheritance of
The use of test-coverage measures (e.g., block-coverage to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test-coverage helps achieve higher defect-coverage and therefore improves software quality. In practice, data often show that defect-coverage and test-coverage grow over time, as additional testing is performed. How
The first subject addressed in this thesis is the contribution of the VSAT luminosity to the lineshape analysis, i.e. to the extraction of the mass and width of the Z0 boson from LEP1 DELPHI data. The VSAT detector has contributed to the lineshape parameter determination by providing a relative luminosity measurement of high accuracy. The second subject of the thesis is the extraction of the helic
Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. To minimize the risks, an optimized pre-investigation program has to be conducted where essential information is gathered in order to make the best decisions throughout the c
When planning new environments, such as homes and workplaces, for the physically disabled it is important to encourage active participation from all those involved. In a research programme initiated at the Lund Institute of Technology, Sweden, a new planning method is being introduced which utilizes computer-aided design as a planning tool. This tool supports and activates the understanding and pa
We consider the effect of symbol rate on the constrained capacity of linear modulation with a fixed spectral density. We show that constrained capacity grows with the symbol rate for some modulation pulses but shrinks with others. Sufficient conditions on the pulse are derived for the constrained capacity to be monotonically increasing with faster symbol rate. Most standard pulses fulfill these.
Purpose of this paper
The purpose is twofold: to map the reviewers’ perspective of evaluation of case based logistics and supply chain management research; and to develop a framework with all criteria needed to design, conduct, and present rigorous case study research. This framework can be used by both researchers and reviewers.

An interview
We discuss the IAU resolutions B1.3, B1.4, B1.5, and B1.9 that wereadopted during the 24th General Assembly in Manchester, 2000, andprovides details on and explanations for these resolutions. It isexplained why they present significant progress over the correspondingIAU 1991 resolutions and why they are necessary in the light of presentaccuracies in astrometry, celestial mechanics, and metrology.
