With rapid urbanization and population growth, Addis Ababa faces a big challenge of dealing with slums in the inner city. It has used up most of its space within its boundary and there are now a number of projects on the pipe line to redevelop the inner city slums. This seems to be the single most pressing issue currently. The recent public housing projects and inner city renewal programs has cau

The increase in global competitiveness and the advancement of digital technology are compelling organizations to innovate by enhancing their product offerings with digital services. Although this phenomenon known as digital servitization is well researched in larger organizations, there is less investigation on how small and medium enterprises (SMEs) manage this trend, particularly in Sweden. This

This thesis explores how entrepreneurs experience and regulate fluctuations in passion, and how these affect their decision-making in high-stakes contexts. While entrepreneurial passion has been widely recognised as a motivating force, little is known about how its intensity fluctuates over time and how such shifts influence strategic behaviour and decisions. Drawing on emotion regulation theory,

Migration causes temporal and energetic constraints during plumage development, which can compromise feather structure and function. In turn, given the importance of a good quality of flight feathers in migratory movements, selection may have favoured the synthesis of feathers with better mechanical properties than expected from a feather production constrained by migration necessities. However, n

In this work, we employ density functional theory to assign vibrational signatures of [FeFe]-hydrogenase intermediates to molecular structures. For this purpose, we perform an exhaustive analysis of structures and harmonic vibrations of a series of CN and CO containing model clusters of the [FeFe]-hydrogenase enzyme active site considering also different charges, counterions, and solvents. The pur

There is an increasing interest in open source, which also goes for enterprise resource planning (ERPs) systems, especially when it comes for small and medium sized enterprises (SMEs). In this article, the focus is on the combination of open source and ERPs, and specifically on what role development of open source ERPs plays in diffusion of ERPs among SMEs. In an effort to be able to explain the i

The location of embryonic lymph node development is determined by the initial clustering of lymphoid tissue-inducer (LTi) cells. Here we demonstrate that both the chemokine CXCL13 and the chemokine CCL21 attracted LTi cells at embryonic days 12.5-14.5 and that initial clustering depended exclusively on CXCL13. Retinoic acid (RA) induced early CXCL13 expression in stromal organizer cells independen

Wavelet-based statistical parametric mapping (WSPM) is an extension of the classical approach in fMRI activation mapping that combines wavelet processing with voxel-wise statistical testing. We recently showed how WSPM, using graph wavelets tailored to the full gray-matter (GM) structure of each individual’s brain, can improve brain activity detection compared to using the classical wavelets that

In order to explore verbal-nonverbal integration, we investigated the influence of cognitive and linguistic ability on gaze behavior during spoken language conversation between children with mild-to-moderate hearing impairment (HI) and normal-hearing (NH) peers. Ten HI-NH and 10 NH-NH dyads performed a referential communication task requiring description of faces. During task performance, eye move

We present some results on the existence of bounded positive solutions to a class of nonlinear second order ordinary diferential equations by using the Schauder-Ekhonov fixed point theorem. An application to the existence of bounded positive solutions to certain quasilinear elliptic equations in two-dimensional exterior domains is also given.

Gold (Au) and platinum (Pt) screen-printed electrodes were modified with Prussian Blue (PB) for the development of amperometric sensors selective for hydrogen peroxide detection. The sensors exhibited sensitivities towards H2O2 equal to 2 A M−1 cm−2 for Au and 1 A M−1 cm−2 for Pt electrodes. The sensors were also employed as the basis for construction of glucose biosensors through further modifica

We propose an inherently origin invariant formulation of specific optical rotation obtained from the conventional velocity gauge expression by subtracting the static limit from the electric dipole-magnetic dipole polarizability: <<(p) over right arrow, (L) over right arrow >>(omega) --> <<(p) over right arrow, (L) over right arrow >>(omega) - <<(p) over right arrow, (L) over right arrow >>(0). Lon

Glucose biosensors based on lyophilised, crystalline and cross-linked glucose oxidase (GOx, CLEC(R)) and commercially available lyophilised GOx immobilised on top of glassy carbon electrodes modified with electrodeposited Prussian Blue are critically compared. Two procedures were carried out for preparing the biosensors: (1) deposition of one layer of adsorbed GOx dissolved in an aqueous solution
