This paper examines two failed land acquisition processes for food and biofuels production in Africa with the aim to establishing more equitable governance strategies. More specifically it explores the roles of certification schemes and codes-of-conduct can play in these processes. The two cases used are the South Korean Daewoo Logistics case in Madagascar and the Swedish SEKAB in Tanzania. The me
We consider the potential for positioning with a system where antenna arrays are deployed as a large intelligent surface (LIS). We derive Fisher-informations and Cram\'{e}r-Rao lower bounds (CRLB) in closed-form for terminals along the central perpendicular line (CPL) of the LIS for all three Cartesian dimensions. For terminals at positions other than the CPL, closed-form expressions for the Fishe
We investigated whether dementia risk factors were associated with prodromal Alzheimer's disease (AD) according to the International Working Group-2 and National Institute of Aging-Alzheimer's Association criteria, and with cognitive decline. A total of 1394 subjects with mild cognitive impairment from 14 different studies were classified according to these research criteria, based on cognitive pe
The trigeminal ganglion plays a key role in primary headache pathophysiology. Calcitonin gene-related peptide (CGRP) and CGRP receptors are expressed in trigeminal neurons that form C-fibers and A-fibers, respectively. In acute migraine and cluster headache attacks, there is release of CGRP into the cranial venous outflow. In addition, intravenous CGRP can induce migraine-like symptoms in migraine
Background/Aim. Hirschsprung's disease (HD) has a skewed gender distribution, with a female to male ratio of 1 : 4. This study aims to examine differences between boys and girls with HD regarding preoperative features and postoperative treatment and outcome. Method. The first part of the study was conducted as a retrospective review of all HD patients who underwent transanal endorectal pull-throug
This review article examines the differences in the approaches taken by economists and historians when interpreting social and economic change in the African past. It is argued that it is a mistake to assume that one discipline has supremacy over the other, let alone monopoly, when it comes to evaluating historical causes of African poverty. One of the shortcomings of the ‘New African Economic His
Background Obesity is linked to cardiovascular diseases and increasingly common in type 1 diabetes mellitus (T1DM) since the introduction of intensified insulin therapy. Our main aim was to explore associations between obesity and depression, anxiety, alexithymia and self-image measures and to control for lifestyle variables in a sample of persons with T1DM. Secondary aims were to explore associat
There is a growing trend to involve citizens in city development to make urban areas more sustainable and livable. The urban living labs approach offers a way to foster new collaborative, trans-disciplinary ways of thinking in urban planning and development, and provides a real-world testing ground for urban innovation and transformation. This handbook aims to bring open innovation and co-creation
Ionotropic glutamate receptors are tetrameric ligand gated ion channels that mediate in ux and ef ux of metal ions in response to glutamate. Positive allosteric modulators of the ionotropic glutamate receptor 2 (GluA2) are promising lead compounds for drugs against cognitive disorders. These compounds bind within the dimeric interface formed by the receptor ligand binding domains (LBDs) attenuatin
In this paper, a compact pattern reconfigurable dual-antenna array is designed at 2.65 GHz for MIMO terminal applications, such as laptops. Each antenna is composed of two layers, i.e., the monopole layer and the PIFA layer. By switching the PIN diodes on each layer, its radiation patterns can be varied between conical and boresight patterns. Two such identical antennas are placed side by side on
TheEl Niño SouthernOscillation(ENSO) isEarth's dominant source of interannual climate variability, but its response to globalwarming remainshighly uncertain1.To improve ourunder standing of ENSO's sensitivity to external climate forcing, it is paramount to determine its past behaviour by using palaeoclimate data and model simulations. Palaeoclimate records show that ENSO has varied considerably si
This paper elucidates the increased need of correct calculations of thermal bridges for low/near zero energy buildings. The variability of the results from calculations of transmission losses for a building can be large if the calculation method within EN ISO 13789:2007 is not fully understood. A survey has been carried out which shows that there are no consensus in Sweden regarding how to define
Results from experiments on laboratory scale fedbatch processes are presented as well as analysis and design of the control system. The main reason for control is to track the drastic growth in feed demand during a cultivation. Variations in the amount and quality of the inocculum makes precalculated dosage schemes of limited value to obtain reproducible cultivation conditions. Two processes have
Drying is an important process in paper manufacturing, where steam heated cylinders are used to dry paper. Control of the moisture content is accomplished by adjusting the steam pressure in the cylinders. This paper presents a nonlinear dynamic model, based on heat and mass balances for steam, cylinder, and paper. It is implemented in the object-oriented modeling language Modelica and is used to e
