Hydrogen derived from algae and cyanobacteria as a decentralized fueling option for hydrogen powered cars : Size, space, and cost characteristics of potential bioreactors

New options are needed to reduce the impact of motor vehicles on climate change and declining fossil fuel resources. Cars which are fueled by hydrogen could be a sustainable method of transportation if suitable technologies can be devised to produce hydrogen in an environmentally benign manner along with the provision of the necessary fueling infrastructure. This paper assesses size, space, and co

Refugee resettlement via machine learning and integer optimization

Around 100,000 refugees are resettled to dozens of countries from conflict zones every year. While there is growing evidence that the initial placement of refugee families profoundly affects their lifetime outcomes, there have been few attempts to optimize resettlement destinations within host countries. We describe how machine learning and integer optimization can be used to empower resettlement

Wealth and poverty in African history

What is new in African economic history? A. G. Hopkins recently presented the “new economic history of Africa” to historians, and argued that it had appeared largely unnoticed by historians of Africa. Since some of the seminal contributions appeared in the early 2000s, there has arguably been a renaissance in African economic history. This chapter discusses some of the challenges of differences in

Patients with acute stroke are less likely to be admitted directly to a stroke unit when hospital beds are scarce : A Swedish multicenter register study

Introduction: It is well established that managing patients with acute stroke in dedicated stroke units is associated with improved functioning and survival. The objectives of this study are to investigate whether patients with acute stroke are less likely to be directly admitted to a stroke unit from the Emergency Department when hospital beds are scarce and to measure variation across hospitals

Multi-parameter optimization of a loose focusing high flux high-harmonic beamline

We perform a multi-dimensional parameter scan in the generation of high-order harmonics, with the main purpose to find the macroscopic conditions that optimize the harmonic yield in a specific spectral domain, around 40 eV for this particular case. The scanned parameters are the laser pulse energy, gas pressure, interaction cell position relative to focus and the cell length, while the fixed param

Maternal copper status and neuropsychological development in infants and preschool children

Introduction: Copper (Cu) is an essential element involved in biological processes; however, excessive Cu could be harmful because of its reactive nature. Very few studies have evaluated its potential neurotoxic effects. We aimed to evaluate the association between maternal Cu levels and children's neuropsychological development. Methods: Study subjects were mother-child pairs from the Spanish INM

The play element in children's musical learning and creativity : NNMPF-conference [Nordisk nettverk for musikkpedagogisk forskning]

Music in different forms is significant in young people's lives. In this presentation play is applied as a theoretical perspective to reach a deeper understanding of children’s musical learning and creativity. This presentation discusses findings from two empirical studies where children ages 6-8 years engage in musical activities: a doctoral a study (Nilsson, 2002) of nine 7-8-year-old Swedish ch

Radiation dosimetry of [68Ga]PSMA-11 in low-risk prostate cancer patients

Background: 68Ga-labeled Glu-NH-CO-NH-Lys(Ahx)-HBED-CC ([68Ga]PSMA-11) has been increasingly used to image prostate cancer using positron emission tomography (PET)/computed tomography (CT) both during diagnosis and treatment planning. It has been shown to be of clinical value for patients both in the primary and secondary stages of prostate cancer. The aim of this study was to determine the effect

Mucin staining is of limited value in addition to basic immunohistochemical analyses in the diagnostics of non-small cell lung cancer

Accurate diagnosis of histological type is important for therapy selection in lung cancer. Immunohistochemical (IHC) and histochemical stains are often used to complement morphology for definite diagnosis and are incorporated in the WHO classification. Our main aim was to compare different mucin stains and assess their value in relation to common IHC analyses in lung cancer diagnostics. Using tiss

Tracing the climate signal : mitigation of anthropogenic methane emissions can outweigh a large Arctic natural emission increase

Natural methane emissions are noticeably influenced by warming of cold arctic ecosystems and permafrost. An evaluation specifically of Arctic natural methane emissions in relation to our ability to mitigate anthropogenic methane emissions is needed. Here we use empirical scenarios of increases in natural emissions together with maximum technically feasible reductions in anthropogenic emissions to

Brain responses to morphologically complex verbs : An electrophysiological study of Swedish regular and irregular past tense forms

The present electrophysiological study investigated irregular versus regular verb form processing in Swedish during reading. In line with previous results from other languages, overregularized verbs, i.e. incorrect irregular stem + regular past tense suffix combinations (e.g. *stjäl + de ‘steal + past tense’), elicited a left-lateralized negativity (LAN) relative to correct irregulars (stal ‘stole

Nutritional status of children with intestinal parasites from a tropical area of Bolivia, emphasis on zinc and iron status

Malnutrition and parasitic diseases are within the major issues in rural areas in developing countries. In this study, the nutritional status, dietary intake including mineral absorption inhibitor (phytate), hematological indicators and trace element status (zinc, iron) were evaluated and associated to the presence of intestinal parasites in a group of children from a rural area of Bolivia. The re

Yet another kinetic mechanism for hydrogen combustion

Recent suggestion by Burke and Klippenstein (2017) that chemically termolecular reactions H + O2 + R may significantly affect kinetic pathways under common combustion situations requires careful analysis, since, if included in contemporary kinetic mechanisms, these reactions affect global reactivity and calculated burning velocities of laminar premixed flames. In the view of their impact, a detail

Respiratory tract deposition of inhaled roadside ultrafine refractory particles in a polluted megacity of South-East Asia

Recent studies demonstrate that Black Carbon (BC) pollution in economically developing megacities remain higher than the values, which the World Health Organization considers to be safe. Despite the scientific evidence of the degrees of BC exposure, there is still a lack of understanding on how the severe levels of BC pollution affect human health in these regions. We consider information on the r

Industrial Symbiosis : towards a design process for eco-industrial clusters by integrating Circular Economy and Industrial Ecology perspectives

Industrial Symbiosis (IS) is a collective approach to competitive advantage in which separate industries create a cooperative network to exchange materials, energy, water and/or by-products. By addressing issues related to resource depletion, waste management and pollution, IS plays an important role in the transition towards sustainable development. In the literature, two conceptual perspectives

The association of self-reported discrimination to all-cause mortality : A population-based prospective cohort study

Discrimination has is an important social determinant of health and though some research has been carried out on this it is mostly from the United States, which may not be generalisable to Europe and Sweden. This study investigated the association between self-reported experiences of repeated discrimination and all-cause mortality in Scania, Sweden. The Scania Public Health survey was sent out in
