Water is a finite resource and should be given the attention it deserves to reduce its depletion through leakages in pipe systems. The authors implemented pressure management strategies linked to fixed and variable discharge (FAVAD), the burst and background estimate (BABE), and orifice principle methodologies to analyze a two-phased comparative method for applying optimal pressure management and

BACKGROUND: Obesity, assessed by body mass index (BMI), is an established risk factor for 13 cancers. We aimed to identify further potential obesity-related cancers and to quantify their association with BMI relative to that of established obesity-related cancers.METHODS: Using Cox regression models on 4,142,349 individuals in Sweden (mean age 27.1 years at weight measurement), we calculated hazar

Freight transportation security concerns both public and private sector institutions, yet their interests are often misaligned, resulting in tensions and trade-offs between performance criteria. Previous research overlooks the connection of public and private interests and provides a fragmented view of the institutions that impact operational conditions and performance within freight transportatioFreight transportation security concerns both public and private sector institutions, yet their interests are often misaligned, resulting in tensions and trade-offs between performance criteria.

The effect of friction between the dowel and the surrounding timber was studied for single dowel-type joints. The joints tested were divided into two groups of joints, where the surface of the dowels differed. For the first group, the dowels had a smooth surface and for the second group the dowels had a rough surface. A contactfree measurement technique was used in the experimental investigatio

Background: Life skills-based approaches are broadly used in HIV prevention programmes world-wide. However, evaluations of such programmes have found mixed evidence for their effects on indicators of safer sexual behaviour. Methods: Questionnaires of 4,381 participants of the Star for Life (SFL) life skills-based prevention programme in South African schools were analysed using binary logistic reg

Quinones are organic molecules that facilitate electron-transfer reactions in terrestrial environments. The reduced forms, hydroquinones, are powerful reductants that can trigger non-enzymatic radical-based decomposition of organic matter and contaminants by simultaneous reduction of iron and oxygen. Iron oxides often occur as coatings on other minerals, thus our study investigated the reactions b

OBJECTIVES: to evaluate the long-term results of stenting in iliac and aortic occlusive disease and identify factors predicting clinical outcome. Design: retrospective study. MATERIALS AND METHODS: 82 patients (87 limbs) with stenoses (n =63) and occlusions (n =24) in the aortoiliac segment were treated with stents. 81 lesions involved the iliac arteries, 3 the infrarenal aorta and 3 the aortic bi

Objective. In published studies there is a lack of data about the risks, management and how women with autoimmune hepatitis (AIH) decide on and are advised about pregnancy. The aim of this study was to investigate how women with AIH consider pregnancies, are advised and pharmacologically treated, as well as the outcome. Material and methods. A questionnaire was mailed to 128 women with AIH diagnos

The unison songs has united people about common goals and experiences in the three great folk movements in Sweden, the Revivalist movement, the Temperance movement and the Socialist movement, especially during the most expansive period, 1850-1920. The aim/purpose of my investigation has been to examine how the different ideolgies are breaking against each other in the songs published for unison so

The performance of four ventilation systems placed in the same building and equipped with plate heat exchangers were examined during spring of 2012. In addition to temperature measurements supply and exhaust air flows measurements were performed. The result shows, that the measured supply and exhaust air flows differ from the design values. Furthermore, the efficiencies of the ventilation units di

Abstract—Resource management in IT–enterprises gain more and more attention due to high operation costs. For instance, web sites are subject to very changing traffic–loads over the year, over the day, or even over the minute. Online adaption to the changing environment is one way to reduce losses in the operation. Control systems based on feedback provide methods for such adaption, but is in natur

The prevalence of autoantibodies against the 65 kD isoform of glutamic acid decarboxylase (GAD65Ab), insulin (IAA), islet cells (ICA), thyroid peroxidase (TPOAb) and thyroglob-ulin (TgAb), in relation to HLA-DR types, was assessed in 310 (HLA in 280) twelve-year-old children during three-year follow-up. Altogether, 26.8% (83?10) of the children were found to carry at least one autoantibody. The HL

The last three decades have seen an increase of tests aimed at measuring an individual’s vocabulary level or size. The target words used in these tests are typically sampled from word frequency lists, which are in turn based on language corpora. Conventionally, test developers sample items from frequency bands of 1000 words; different tests employ different sampling ratios. Some have as few as 5 o

Reconciliation research consists of two practices, one focusing on the emotional and healing aspects of the process and another that focus on the political and legal actions. Yeudith Auerbach created a theory, the reconciliation pyramid, which aims to manage both aspects. The purpose of this thesis is to apply Auerbach's theory to the reconciliation process in two empirical cases, the Rwandan

As a primary driver of climate change, energy systems are often affected by the type of “self-perpetuation and lock-in” that characterize so-called ‘wicked problems’. Although it has a relatively clean energy system, Canada still has provinces (e.g. Alberta, Saskatchewan) that possess carbon-intensive power grids, and provinces that have experienced minimal renewable energy development other tha

Sverige har sedan länge ansetts vara ett land befriat från svågerpolitik och korruption. Korruption är dock ett vitt begrepp som härstammar från det latinska ordet corrumpere, vilket betyder muta. Följaktligen omfattas den straffrättsliga terminologin av givande och tagande av muta av begreppet korruption. Korruption anses vara ett medel för att otillbörligen påverka besluts- och handlingsprocesseSweden has long been considered a country free from nepotism and corruption. Corruption is however a broad term which derives from the Latin word corrumpere, meaning bribe. Consequently the criminal terminology of giving and receiving bribes comprises the concept of corruption. Corruption is a way to improperly influence the decision making and processes in a society. The damaging effects on a soc

In 2006 a new law in Peru was proposed by the government, compelling civil society organizations to work for the same development goals as the government, which basically meant to account for their funding, and if it was not in line with the goals of the government, organizations would be fined or suspended. I have conducted a minor field study in Peru and investigated the relationship between the

This paper develops a model of human capital accumulation with on-the-job learning subject to obsolescence risk. The model analytically characterizes trade-offs of reforming the level of income tax progressivity and matches well income inequality in the US. An enriched version is used to quantitatively investigate optimal tax progressivity in the US. In contrast to standard models with exogenous i
