Upper limits on direct photon production were determined as a function of the transverse momentum for 0.7 < pT ≤ 3.2 GeV/c with the WA98 experiment in p + C and p + Pb collisions at . The results are compared to direct photon measurements in Pb + Pb collisions at by WA98. Implications for a possible thermal direct photon contribution are discussed.

The 2nd generation bioethanol will be produced from lignocellulose biomass including agricultural residues such as bagasse, straw, and stover, forest products residues and dedicated energy crops. The bioconversion of lignocellulose raw materials to ethanol requires microorganisms that are able (i) to ferment both hexose and pentose sugars present in lignocellulose and (ii) to tolerate and to remai

The New Zealand emissions trading scheme (ETS) wasintroduced by legislation in 2008. The legislated objectives asstated in section 3 of the Climate Change Response Act 2002are to ‘support and encourage global efforts to reduce theemission of greenhouse gases by (i) assisting New Zealandto meet its international obligations under the [UNFCCC].

Monitoring and evaluation of malaria control in pregnancy is essential for assessing the efficacy and effectiveness of health interventions aimed at reducing the major burden of this disease on women living in endemic areas. Yet there is no currently integrated strategic approach on how this should be achieved. Malaria control in pregnancy is formulated in relation to epidemiological patterns of e

Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton-proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb(-1)

OBJECTIVE: People with disabilities find it harder to enter the labour market than people without disabilities and those with a mental illness are, in relation to people with other disabilities, employed at an essentially lower extent. Many are effectively helped by the vocational rehabilitation model Individual Placement and Support (IPS), but there are still many individuals left in undesired un

We report on fabrication and optical characterization of GaAs nanopillar (NP) arrays, obtained using a combination of low-cost mask generation by self-assembled silica particles (nanosphere lithography) and dry etching. Tapered structures (conical and frustum NP arrays) are fabricated by appropriate optimization of process parameters. Significant suppression of surface reflectance is observed for

Introduction: Knowledge of longitudinal progression in mild Alzheimer’s disease (AD) is required for the evaluation of disease-modifying therapies. Our aim was to observe the effects of long-term cholinesterase inhibitor (ChEI) therapy in mild AD patients in a routine clinical setting. Methods: This was a prospective, open-label, non-randomised, multicentre study of ChEI treatment (donepezil, riva

Traffic congestion is a persistent problem in modern urban environments, causing delays, increasing pollution, and negatively affecting the quality of life of millions of city dwellers. As urban populations grow, the need for intelligent traffic man- agement systems becomes more pressing. This thesis presents a novel approach to real-time traffic management using edge computing in conjunction w

Almost 30 years have passed since the dismantling of South Africa’s apartheid system, putting an end to the long history of racial segregation, discrimination, and oppression. But has it really changed? This research highlights the emergence of Black Economic Empowerment (BEE) as an affirmative policy instrument to advance land reform and rectify the enduring inequalities in the country’s agricult

The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. The glacial history of Vombsänkan, which is controlled by sequential geological events such as active ice-margin and stagnant ice, formation of dead ice as well as

With aging populations, unequal access to care, and shortages of staff, healthcare systems today are facing many challenges. Technology advancements, with artificial intelligence (AI) in particular, have been one of the main drivers of innovation in multiple industries. Although the healthcare sector is moving slower compared to other industries, there is great potential for relieving healthcare w

This thesis investigates the narratives Icelandic politicians use to discuss crime, particularly focusing on themes of cultural purity and danger. The study aims to understand how these narratives influence public perception and policy. Politicians often frame crime as a significant threat to societal norms and values, using various rhetorical strategies to evoke emotions such as fear and urgency.

Rebound effects, though well-documented in consumption areas such as household energy consumption, have been far less explored in nutrition. This is despite the fact that the nutrition may be just as crucial of a consumption area when considering how to reduce carbon footprints in personal lifestyle choices. This thesis explores the existence of one of the possible mechanisms behind a rebound effe

This thesis presents a method, from an article by Gouveia and Stone, for solving resonant ODE:s as well as ODE:s with multiple roots, based on perturbation theory. It also gives a mathematical justification for the method as well as background on resonance and repeated roots. Later in the thesis we use the method to solve a number of ODE’s, illustrating its usefulness.

Automation with the use of robotics is a crucial trend across industries, enhancing efficiency and quality while improving health and safety conditions by minimizing human exposure to hazardous tasks. Alfa Laval, a global provider of products within heat transfer, separation, and fluid handling, is embracing this trend by exploring how to solve labor-intensive processes like the production of rubb
