Making the sustainable more sustainable : public transport and the collaborative spaces of policy translation

This paper investigates where and how sustainable transport goals are translated into public transport planning and operations. The case where this is explored is the Regional Public Transport Authority (RPTA) in Stockholm, Sweden. By drawing upon recent discussions on policy translation and political–administrative relationships, sustainable transport is found to be translated in two different co

Accurate Time - Domain Modeling of Multi-Finger pHEMT layout Structure based on Transmission line Theory

In this paper, a fully distributed modeling of double gate InGaAs pHEMT as a 5-line active coupled transmission line is described. In order to apply the transmission line theory, a proper equivalent lumped circuit model is allocated for the differential length of the double gate quintuple line transistor and the active multi-conductor transmission line equations are obtained. The passive element v

Large-signal and Distributed-based Model of mm-wave Multi-Finger pHEMTs using Time-Domain Technique

The finite-difference time-domain (FDTD) method is used for the large-signal modeling of a multifinger pHEMT, which is considered as five nonlinear coupled distributed transmission lines. The developed model, which is based on the exact physical layout of multifinger pHEMT, not only accurately describes the propagation effects along the electrodes at higher frequencies but it also includes major n

The impact of tinnitus on n-back performance in normal hearing individuals

Background: Tinnitus sufferers commonly report concentration difficulties. Despite several previous studies investigating this, the underlying cause and the role of hearing status remains unclear. Purpose: To investigate whether there are any differences between normal hearing individuals with and without tinnitus in terms of working memory capacity, and whether working memory capacity correlates

Strategic communication management in the non-profit sector: a simplified model

A model for strategic communication management was developed in South Africa on the basis of the excellence study and relationship management theories. This normative, theoretical model has been applied as part of a project in non-profit organisations (NPOs), government institutions and small-to-medium sized companies. However, the operational reality of organisations’ communication practices has

Shape fluctuations and water diffusion in microemulsion droplets : A nuclear spin relaxation study

Water 2H and 17O spin relaxation data for the microemulsion phase in the AOT/D 2O/isooctane system are reported. The difference between the transverse (R 2) and the longitudinal (R 1) relaxation rates has been measured as function of droplet size, droplet volume fraction, temperature, and resonance frequency. The 2H longitudinal relaxation rate dispersion has been measured over an extensive freque

Hydration of ionic surfactant micelles from water oxygen-17 magnetic relaxation

Water oxygen-17 relaxation rates have been measured for aqueous solutions of micelles composed of ionic surfactants of varying alkyl chain length, head group, and counterion. The concentration of surfactant and salt was also varied. From these measurements, supplemented with relaxation data for short-chain molecules and with quadrupolar splittings from anisotropic mesophases, we derive structural

Suppressed ACTH Is Frequently Unrelated to Autonomous Cortisol Secretion in Patients With Adrenal Incidentalomas

Objective: ACTH is considered a weak marker for autonomous cortisol secretion (ACS) in patients with adrenal incidentalomas (AIs). Our aim was to investigate suppressed basal ACTH as a marker of ACS and to elucidate why this criterion is of limited value. Methods: Basal ACTH and cortisol after overnight dexamethasone suppression test (cortisolONDST) were measured in 198 patients with unilateral AI

Sustainable Multi-echelon Inventory Control with Shipment Consolidation and Volume Dependent Freight Costs,

This paper provides exact analysis of a model for sustainable control of a one-warehouse-N-retailer inventory system with time based shipment consolidation. The model is motivated by discussions with industry, and involves the possibility to reserve intermodal transportation capacity in combination with truck transports available on demand. Inventories are reviewed continuously while shipments fro

Extravascular lung water index: Diagnostic accuracy and relation to lung injury and mortality in patients with shock

INTRODUCTION. The diagnosis of acute lung injury may be more robust if more accurate physiological markers can be identified. Extravascular lung water index (EVLWI) may be useful and has been shown to correlate with respiratory function and mortality in patients with sepsis and ARDS. Whether this applies to a wider population, and which index performs best, are unclear. OBJECTIVES. We hypothesized
