Blended Wing Aerodynamic Research

In this study, a blended wing body (BWB) aircraft model was designed, and will be fabricated and tested with the objective of maximizing aerodynamic efficiency as well as determining if boundary layer ingestion from top surface mounted engines results in less drag. The purpose of this study is to prove that BWB aircraft designs are more efficient than traditional cylindrical fuselage and wing designs. Wind tunnel testing as well as computational fluid dynamic (CFD) analysis is expected to support this hypothesis. Both of these tasks are to be completed or are currently in progress. Drag reduction from boundary layer ingestion as well as a more aerodynamic body are the two focus points of this project. Showing that both of these factors are improved by using a BWB design (and thus result in less energy required to fly) is the goal of this study

Angiotensin II potentiates α-adrenergic vasoconstriction in the elderly

Abstract Aging is characterized by increased sympatho-excitation, expressed through both the α-adrenergic and RAAS (renin-angiotensin-aldosterone) pathways. Although the independent contribution of these two pathways to elevated vasoconstriction with age may be substantial, significant cross-talk exists that could produce potentiating effects. To examine this interaction, 14 subjects (n = 8 young, n = 6 old) underwent brachial artery catheterization for administration of AngII (angiotensin II; 0.8-25.6 ng/dl per min), NE [noradrenaline (norepinephrine); 2.5-80 ng/dl per min] and AngII with concomitant α-adrenergic antagonism [PHEN (phentolamine); 10 μg/dl per min]. Ultrasound Doppler was utilized to determine blood flow, and therefore vasoconstriction, in both infused and contralateral (control) limbs. Arterial blood pressure was measured directly, and sympathetic nervous system activity was assessed via microneurography and plasma NE analysis. AngII sensitivity was significantly greater in the old, indicated by both greater maximal vasoconstriction ( − 59 + − 4 % in old against − 48 + − 3 % in young) and a decreased EC 50 (half-maximal effective concentration) (1.4 + − 0.2 ng/dl per min in old against 2.6 + − 0.7 μg/dl per min in young), whereas the maximal NE-mediated vasoconstriction was similar between these groups ( − 58 + − 9 % in old and − 62 + − 5 % in young). AngII also increased venous NE in the old group, but was unchanged in the young group. In the presence of α-adrenergic blockade (PHEN), maximal AngII-mediated vasoconstriction in the old was restored to that of the young ( − 43 + − 8 % in old and − 39 + − 6 % in young). These findings indicate that, with healthy aging, the increased AngII-mediated vasoconstriction may be attributed, in part, to potentiation of the α-adrenergic pathway, and suggest that cross-talk between the RAAS and adrenergic systems may be an important consideration in therapeutic strategies targeting these two pathways

Putting Children First: New Frontiers in the Fight Against Child Poverty in Africa

Despite important strides in the fight against poverty in the past two decades, child poverty remains widespread and persistent, particularly in Africa. Poverty in all its dimensions is detrimental for early childhood development and often results in unreversed damage to the lives of girls and boys, locking children and families into intergenerational poverty. This edited volume contributes to the policy initiatives aiming to reduce child poverty and academic understanding of child poverty and its solutions by bringing together applied research from across the continent. With the Sustainable Development Goals having opened up an important space for the fight against child poverty, not least by broadening its conceptualization to be multidimensional, this collection aims to push the frontiers by challenging existing narratives and exploring alternative understandings of the complexities and dynamics underpinning child poverty. Furthermore, it examines policy options that work to address this critical challenge.Comparative Research Programme on Poverty (CROP) at the University of Bergen.publishedVersio
