This study explored the ability of blind and sighted listeners to detect reflections, "echoes", of burst trains or continuous noise. Echo detection was compared by presenting 5 ms bursts, rates from 1 to 64 bursts, with a continuous white noise, all during 500 ms. Sounds were recorded in an ordinary room through an artificial binaural head, the loudspeaker 1 m behind it. The reflecting object was

Purpose - The purpose of this paper is to carry out a numerical investigation to study forced convection for a tube with fins on the inner and outer surfaces with water as the base fluid and adding particles of CuO to have a nanofluid. Design/methodology/approach - Three geometries are designed by using Solid Works and the number of inside fins is 20 with height 6 mm and thickness 1mm. The number

On 25 May 1993, the United Nation Security Council took the extraordinary and unprecedented step to establish the International Criminal Tribunal for the Former Yugoslavia (ICTY) as means for restoration and maintenance of international peace and security. This was a major event for the all those who are concerned about serious breaches of international humanitarian law and the introduction of law

Roten till cancer? Cancer är en ledande orsak till en stor mängd dödsfall i världen och därför en fruktad sjukdom. Forskningen gör dock framsteg och man kommer allt närmre svaren på gåtorna. På senare år har det föreslagits att en speciell typ av celler, cancerstamceller, är drivande och ligger bakom flera av cancersjukdomarnas egenskaper. Alla organismer är uppbyggda av celler, den stora majoriIn recent years increasing evidence supporting the stem cell hypothesis have emerged and cancer stem cells (CSCs) have been reported to have been isolated in a wide variety of cancers. This CSC population has been attributed to contribute to the therapeutic resistance of many cancers and it is thus of great interest to find new therapeutic options targeting these cells. In ileal carcinoids however

Priming effects have gotten revived interest in the last decade due to the concerns of global warming. Priming are defined as an increase in decomposition of soil organic matter due to the addition of organic or mineral substances. The worldwide used herbicide glyphosate is rapidly degraded by microorganisms. Hence, it might give rise to priming effects in soils. This was tested by adding glyphosa

By testing theories from the likes of Seymour Martin Lipset and Francis Fukuyama, this thesis aims to illuminate the correlations between the size of a nation’s middle class and the stability and rigor of its democracy. Using quantitative data on democracy and middle class size in the time surrounding the financial crisis of 2008-2010, this thesis illustrates the parallel declines in both democrac

The lack of accountability for human rights violations arising out of the activities of multinational enterprises has been identified as a key impediment to the fulfillment of universal human rights and the corresponding access to remedy for victims. However, the last couple of years have witnessed an increasing movement to bridge the accountability gap on the national and international level. Th

High-Level Synthesis(HLS) is a design methodology that enables designers to implement hardware from high-level coding languages, such as C, C++, or System C. It provides designers with the ability to convey their design at a higher level of abstraction, which allows more emphasis on an algorithm and functional aspects of design instead on low-level hardware details. As precise control of signal ti

The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S

The overall aim of thesis was to explore frail older people’s experiences of receiving healthcare and/or social services and to investigate healthcare consumption and costs in both men and women and in different age groups in the two years prior to the introduction of long-term municipal care. A second aim was to explore a preventive intervention in a pilot study using case managers to older peopl

Although climate is known to be one of the key factors determining animal species distributions amongst others, projections of global change impacts on their distributions often rely on bioclimatic envelope models. Vegetation structure and landscape configuration are also key determinants of distributions, but they are rarely considered in such assessments. We explore the consequences of using sim

Budgerigars (Melopsittacus undulatus) and Bourke's parrots (Neopsephotus bourkii) are closely related birds with different activity patterns. Budgerigars are strictly diurnal while Bourke's parrots are active in dim twilight. Earlier studies show that the intensity threshold of colour vision is similar in both species while Bourke's parrots have larger eyes with a higher density of rods than budge

A measurement of the total pp cross section at the LHC at root s = 7 TeV is presented. In a special run with high-beta* beam optics, an integrated luminosity of 80 mu b(-1) was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the diffe

Knowledge about the need for care of elderly individuals in community dwellings and the factors affecting their needs and support is limited. The aim of this study was to characterize the frailty of a population of elderly individuals living in community dwellings in Sweden in relation to co-morbidity, use of drugs, and risk of severe conditions such as malnutrition, pressure ulcers, and falls. In

Each year millions of people receive emergency relief items from humanitarian organizations following disasters and crises. While significant time and resources have been invested in identifying the needs of affected populations and how to address those needs, significantly less focus has been given to environmental impacts of these response operations. These impacts can result in substantial nega
