Accounts of Northern Barbarians in Tacitus' Annales : A Contextual Analysis

The Roman historian Tacitus is not only our most important source for the Early Roman Empire, but also a literary artist second to none. His fragmentarily preserved Annales deals with the imperial rule established by the first emperor Augustus, the Julio-Claudian dynasty (AD 14 – 68). Through his scathing analyses of the consequences of autocratic government, Tacitus has established himself as an

The effects of aerobic exercise and the impact of migraine and co-existing tension-type headache and neck pain

The overall aims of this thesis were to investigate the effects of an aerobic exercise program and the impact of migraine and co-existing TTH and NP in persons with these combined conditions. This thesis is based on four studies.In study I, a new questionnaire, Impact of Migraine, TTH and NP (Impact M-TTH-NP), was developed. This questionnaire covered pain, triggers, psychosocial,socioeconomic and

The Land-Labour Hypothesis in a Settler Economy : Wealth, Labour and Household Composition on the South African Frontier

Traditional frontier literature identifies a positive correlation between land availability and fertility. A common explanation is that the demand for children as labour is higher in newly established frontier regions compared to older and more densely populated farming regions. In this paper we contribute to the debate by analysing the relationship between household composition and land availabil

Proteomic Profiling of Diffuse Large B-Cell Lymphomas

Objective: The aim of this study was to identify differences in proteome profiles of diffuse large B-cell lymphoma (DLBCL) of nongerminal center (non-GC) versus GC type in the search for new markers and drug targets. Methods: Six DLBCL, with 3 repeats for each, were used for the initial study by proteomics: 3 non-GC and 3 GC DLBCL cases. For immunohistochemistry, tissue microarrays were made from

Whole-genome sequencing of the blue whale and other rorquals finds signatures for introgressive gene flow

Reconstructing the evolution of baleen whales (Mysticeti) has been problematic because morphological and genetic analyses have produced different scenarios. This might be caused by genomic admixture that May have taken place among some rorquals. We present the genomes of six whales, including the blue whale (Balaenoptera musculus), to reconstruct a species tree of baleen whales and to identify phy

Electrification of rural Mozambique : Sustainable energy solutions

The UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. The effects on socioeconomic development by access to safe, affordable, and clean electricity stands out as educational benefits, income improvement, and health progress. However, the electrification rate has been slow for sub-Saharan Africa and

Effect of Ge autodoping during III-V MOVPE growth on Ge substrates

During the MOVPE growth of III-V layers on Ge substrates, Ge atoms can be evaporated or etched from the back of the wafer and reach the growth surface, becoming incorporated into the epilayers. This is the so-called Ge autodoping effect, which we have studied through a set of growth experiments of GaInP and Ga(In)As layers lattice matched to Ge substrates, which have been characterized by Secondar

Performance of QuantiFERON-TB gold plus for detection of latent tuberculosis infection in pregnant women living in a tuberculosis- and HIV-endemic setting

We evaluated the performance of QuantiFERON-TB Gold Plus (QFT-Plus), which includes two Mycobacterium tuberculosis antigen formulations (TB1 and TB2), for detection of latent tuberculosis infection during pregnancy. Eight-hundred-twenty-nine Ethiopian pregnant women (5.9% HIV-positive) were tested with QFT-Plus, with bacteriological sputum analysis performed for women with clinically suspected tub

Ultrasonic Additive Manufacturing as a form-then-bond process for embedding electronic circuitry into a metal matrix

Ultrasonic Additive Manufacturing (UAM) is a hybrid manufacturing process that involves the layer-by-layer ultrasonic welding of metal foils in the solid state with periodic CNC machining to achieve the desired 3D shape. UAM enables the fabrication of metal smart structures, because it allows the embedding of various components into the metal matrix, due to the high degree of plastic metal flow an

Rotor-stator mixers : From batch to continuous mode of operation-A review

Although continuous production processes are often desired, many processing industries still work in batch mode due to technical limitations. Transitioning to continuous production requires an in-depth understanding of how each unit operation is affected by the shift. This contribution reviews the scientific understanding of similarities and differences between emulsification in turbulent rotor-st

Genome dynamics and evolution in yeasts : A long-term yeast-bacteria competition experiment

There is an enormous genetic diversity evident in modern yeasts, but our understanding of the ecological basis of such diversifications in nature remains at best fragmented so far. Here we report a long-term experiment mimicking a primordial competitive environment, in which yeast and bacteria co-exist and compete against each other. Eighteen yeasts covering a wide phylogenetic background spanning

Lung cancer in young women in southern Sweden : A descriptive study

Introduction: Lung cancer, a common malignancy and cause of cancer-related deaths, is strongly linked to several environmental exposures, and thus primarily affects the elderly. Formerly a man's disease, its incidence is rising among women, and lung cancer is now more common in women than men in Sweden. Women are particularly over-represented among young patients. While overall cancer mortality in

The outcome of epiduroscopy treatment in patients with chronic low back pain and radicular pain, operated or non-operated for lumbar disc herniation : A retrospective study in 88 patients

Background: Patients with lumbar disc herniation are treated with physiotherapy/medication and some with surgery. However, even after technically successful surgery some develop a failed back syndrome with persistent pain. Our aim was to evaluate the efficacy of epiduroscopy in patients who suffer chronic low back pain and/or radicular pain with or without surgery and the gender difference in outc

Hemodynamic forces in the left and right ventricles of the human heart using 4D flow magnetic resonance imaging : Phantom validation, reproducibility, sensitivity to respiratory gating and free analysis software

Purpose To investigate the accuracy, reproducibility and sensitivity to respiratory gating, field strength and ventricle segmentation of hemodynamic force quantification in the left and right ventricles of the heart (LV and RV) using 4D-flow magnetic resonance imaging (MRI), and to provide free hemodynamic force analysis software. Materials and methods A pulsatile flow phantom was imaged using 4D

Recent upgrades of the neutron reflectometer D17 at ILL

The vertical sample-plane reflectometer D17 at the Institut Laue–Langevin in Grenoble, France, has undergone several major upgrades since its commissioning, which are summarized in this article. The three major improvements are (i) a new focusing guide, increasing the usable flux on the sample by a factor of 2.5; (ii) a new beam polarizer and new spin flippers, allowing for the use of polarized ne
