Effect of Oligomerization of Counterions on Water Activity in Aqueous Cationic Surfactant Systems

A sorption calorimetry study of cationic cetyltrimethyl ammonium surfactants with four different counterions was performed. The counterions were acetate, succinate, citrate, and butyl tetracarboxylate with formal charges ranging from 1 to 4, respectively. The counterions with 2-4 charges can be considered as oligomers. In all the cases, hydration experiments started with dry solid phases that upon

Oscillator strengths for high-excitation Ti II from laboratory measurements and calculations

This work reports new experimental radiative lifetimes of six 3d2(3F)5s levels in singly ionized titanium, with an energy around 63 000 cm-1 and four 3d2(3F)4p odd parity levels where we confirm previous investigations. Combining the new 5s lifetimes with branching fractions measured previously by Pickering et al., we report 57 experimental log gf values for transitions from the 5s levels. The lif

Nuclear magnetic relaxation by the dipolar EMOR mechanism : Three-spin systems

In aqueous systems with immobilized macromolecules, including biological tissue, the longitudinal spin relaxation of water protons is primarily induced by exchange-mediated orientational randomization (EMOR) of intra- and intermolecular magnetic dipole-dipole couplings. Starting from the stochastic Liouville equation, we have developed a non-perturbative theory that can describe relaxation by the

Ordkonst och levnadskonst : Det skrivande subjektet i John Ashberys, Yves Bonnefoys och Inger Christensens diktning

The chief aim of this thesis is to investigate the use of language called poetry during the second half of the 20th century and how the writing subject is implicated in it. Building on the theoretical perspectives enabled by Michel Foucault’s late work on the technologies of the self, I analyze the practices of writing in John Ashbery’s, Inger Christensen’s and Yves Bonnefoy’s poetry. The introduc

Perceptual and acoustic differences between authentic and acted nonverbal emotional vocalizations

Most research on nonverbal emotional vocalizations is based on actor portrayals, but how similar are they to the vocalizations produced spontaneously in everyday life? Perceptual and acoustic differences have been discovered between spontaneous and volitional laughs, but little is known about other emotions. We compared 362 acted vocalizations from seven corpora with 427 authentic vocalizations us

3.6 A 60pJ/b 300Mb/s 128×8 Massive MIMO precoder-detector in 28nm FD-SOI

Further exploitation of the spatial domain, as in Massive MIMO (MaMi) systems, is imperative to meet future communication requirements [1]. Up-scaling of conventional 4×4 small-scale MIMO implementations to MaMi is prohibitive in-terms of flexibility, as well as area and power cost. This work discloses a 1.1mm2 128×8 MaMi baseband chip, achieving up to 12dB array and 2× spatial multiplexing gains.

Design and Analysis of the Medium-β Elliptical Cavities for the European Spallation Source Accelerator

This thesis is dedicated to the design and analysis of superconductingelliptical cavities. Elliptical cavities play a central role in modern particle ac-celerators due to their high efficiency. After an introduction to the EuropeanSpallation Source project, the thesis goes through the design of the medium-βcavity. The RF design of the inner cell and end cell are presented in sequencein paper I . T

ESS Elliptical Cavities and Cryomodules

The accelerator of the European Spallation Source (ESS) is a 5 MW proton linac to be built in Lund Sweden. Its superconducting section is composed of 3 cavity families: double spoke resonators, medium beta and high beta elliptical multi-cell cavities. This paper presents the electromagnetic and mechanical design of the elliptical cavities. Both elliptical families are housed in 4-cavity cryomodule

On the Optimal Design of Elliptical Superconducting Cavities

In this paper a linear regression analysis is used to analyze the behavior of the inner cell of an elliptical cavity. The aim is to understand how the RF parameters are correlated to each other and how they are affected by the change of the geometric parameters. This is done by fitting the RF data to a linear model. The data is obtained by simulating a set of different inner cells automatically by

Identification of Visceral Leishmaniasis-Susceptible Areas using Spatial Modelling in Southern Caucasus

This study explores the application of spatial modelling techniques to generate susceptibility maps for a neglected zoonotic disease, visceral leishmaniasis (VL), in an endemic area in southern Caucasus that includes Iran, Armenia and Azerbaijan. The social and physical environment of southern Caucasus has been mainly characterized by the presence of several factors that are strongly associated wi

Towards a systemic framework for capturing and explaining the effects of academic RD

In the EU, it is believed that the potential benefits of academic R&D are not fully reaped. Much attention is, therefore, given to enhancing commercialisation in the form of academic spin-offs, patents and licences. There are, however, a number of problems with this way of analysing the effects of academic R&D. Its contribution must instead be captured by a systems approach and we go some

The many ways of academic researchers : How is science made useful?

In assessing the performance of academic research, there is a growing interest in combining excellence with impact criteria. A frequently encountered belief is that impact should be understood in terms of new firms and patents. Others argue that academic R&D generates impacts that greatly exceed such commercialization efforts by academic researchers. The tension between these two beliefs revea

Identifying, explaining and improving the effects of academic R&D : The case of nanotechnology in Sweden

It is commonly believed that the academic sector does not generate enough value for society. This value is often measured in terms of new firms, patents and products, leading to policy responses which aim to enhance ‘commercialisation’ by academics. However, others maintain that academic research generates benefits in many ways, some of which are difficult to measure, and that policy must look bey

An in-depth study of direct and indirect impacts from the research of a physics professor

Some policymakers believe that academic R&D generates insufficient economic benefits. However, they often exclude the long-term and multi-dimensional impacts that are mediated through the activities of companies, students or policymakers. This case study, which is mainly interview-based, traces and characterises such impacts applying the technological innovation systems approach to the case of

The Impact of Academia on the Dynamics of Innovation Systems : Capturing and explaining utilities stemming from academic research and development

The notion that academic research creates societal benefits is widely recognised. However, there are varying perceptions of what such benefits may include, and diverse ideas regarding the ways in which they are created. Some research policy actors expect academic research to generate tangible and direct outputs related to commercialisation, such as spin‐off companies, patents and licences. Others
