Synthesis, Structural Characterization, and Ab Initio Study of Cu(5+δ)In(2+x)Sb(2-x): A New B8-Related Structure Type.

A new ternary orthorhombic compound with the formula Cu(5+δ)In(2+x)Sb(2-x), crystallizing in the space group Cmc2(1) with 36 atoms per unit cell [a = 10.1813(4) Å, b = 8.4562(4) Å, c = 7.3774(2) Å, Z = 4], has been synthesized by conventional high-temperature methods. The structure is based on the B8 archetype (NiAs/Ni(2)In) and features In/Sb ordering as well as ordering of interstitial copper. D

Stock Rationing in a Continuous Review Two-Echelon Inventory Model

In this paper we consider a 1-warehouse, N-retailer inventory system where demand occurs at all locations. We introduce an inventory model which allows us to set different service levels for retailers and direct customer demand at the warehouse. For each retailer a critical level is defined, such that a retailer replenishment order is delivered from warehouse stock if and only if the stock level e

Development of biosensors based on hexacyanoferrates.

Ferric and copper hexacyanoferrates (PB and CuHCF, respectively) were electrodeposited on glassy carbon electrodes providing a suitable catalytic surface for the amperometric detection of hydrogen peroxide. Additionally glucose oxidase was immobilized on top of these electrodes to form glucose biosensors. The biosensors were made by casting glucose oxidase-Nafion layers onto the surface of the mod

Piaget and Vygotsky on the child becoming sign-minded

As the child grows up it becomes more and more a part of the adult world of communication and understanding. Semiotic studies of the development of signs in children are remarkably few, as if the mere existence of signs were taken for granted. The studies in the child’s cognitive development conducted by Piaget and Vygotsky in the last century still have the capacity to influence theoretical claim

Nile blue adsorbed onto silica gel modified with niobium oxide for electrocatalytic oxidation of NADH

A study of modified carbon paste electrode employing Nile blue (NB) adsorbed on silica gel modified with niobium oxide (SN) for electrocatalytic oxidation of reduced nicotinamide adenine dinucleotide (NADH) is described. The adsorbed organic dye on SN was used to prepare a modified carbon paste electrode to investigate its electrochemical properties. The formal potential (E-o') of the adsorbed NB

The Influence of Biodiversity Provision on the Cost Structure of Swedish Dairy Farming

Multi-functionality and the provision of eco-system services are politically highly prioritised aspects of farming. This study uses a Symmetric Generalised McFadden cost function to analyze the relationship between costs of production and the provision of biodiversity for Swedish milk farms. Biodiversity indicators are based on the number of valuable plant species present at the farm and are model

Looking at hydrogen motions in confinement The uniqueness of Quasi-Elastic Neutron Scattering

Why in a barren and hot desert, clays can contain a significant fraction of water? Why does concrete crack? How can we demonstrate that complexation of a drug does not alter its conformation in a way that affects its functionality? In this paper we present results on various studies using Quasi-Elastic Neutron Scattering aimed at clarifying these questions. To allow for a better understanding of n

A conceptual study of OFDM-based multiple access schemes: Part 3 - Performance evaluation of a coded system

This paper is part of a conceptual study of a multiuser OFDM system. In previous reports we have examined requirements for the air interface and presented uncoded performance (in terms of bit error rate) for the uplink of such systems. In this report we adopt the user allocation structure from the previous parts of the study and examine the role of channel coding. We present performance simulation

Uncompensated blood loss is not tolerated during acute normovolemic hemodilution in anesthetized pigs

Clinically, hemodilution to a hematocrit of 9% has been studied, but the effects of hypovolemia during this degree of hemodilution have not been elucidated. We studied the response to blood loss during extreme hemodilution and evaluated indicators of hypovolemia. Systemic and myocardial hemodynamics, oxygen transport, and blood lactate concentrations were measured in 12 anesthetized pigs exposed t

Integrating the “dead capital” in models of cadastral systems

Cadastral Systems have developed during the latest decades, impelled by improved information technology. Cadastral projects have become more strategic in a development perspective, with expected long-term returns in economic growth.

An improvement of an existent information system requires an understanding of the basis of the current model, its coverage and the processes of change. The l

Non-endocrine late complications in children after allogeneic haematopoietic SCT

Non-endocrine events represent a heterogeneous group of complications occurring in children who survive long term after haematopoietic SCT. This review highlights the late sequel in a growing child. The preparative regimen itself with high-dose chemotherapy and/or radiotherapy (TBI) or the treatment given before the transplant procedure may cause organ damage with permanent sequel. Immune reconsti

Axillary recurrence rate after negative sentinel node biopsy in breast cancer - Three-year follow-up of the Swedish Multicenter Cohort Study

Background: Sentinel lymph node biopsy is an established staging method in early breast cancer. After a negative biopsy, most institutions will not perform a completion axillary dissection. The present study reports the current axillary recurrence (AR) rate, overall and disease-free survival in the Swedish Multicenter Cohort Study. Methods: From 3534 patients with primary breast cancer <= 3 cm pro
