Impact of reactive settler models on simulated WWTP performance

Including a reactive settler model in a wastewater treatment plant model allows representation of the biological reactions taking place in the sludge blanket in the settler, something that is neglected in many simulation studies. The idea of including a reactive settler model is investigated for an ASM1 case study. Simulations with a whole plant model including the non-reactive Takacs settler mode

The effect of exercise training on hormone-sensitive lipase in rat intra-abdominal adipose tissue and muscle

1. Adrenaline-stimulated lipolysis in adipose tissue may increase with training. The rate-limiting step in adipose tissue lipolysis is catalysed by the enzyme hormone-sensitive lipase (HSL). We studied the effect of exercise training on the activity of the total and the activated form of HSL, referred to as HSL (DG) and HSL (TG), respectively, and on the concentration of HSL protein in retroperito

Measurement of the energy dependence of hadronic jet rates and the strong coupling alpha(s) from the four-jet rate with the DELPHI detector at LEP

Hadronic events from the data collected with the DELPHI detector at LEP within the energy range from 89 GeV to 209 GeV are selected, their jet rates are determined and compared to predictions of four different event generators. One of them is the recently developed APACIC++ generator which performs a massive matrix element calculation matched to a parton shower followed by string fragmentation. Th

Search for Linking Transitions in 143Eu

An experiment was performed with the Gammasphere Ge-detector array, and the Microball charged particle detector, to search for transitions involved in the decay from the yrast superdeformed band in Eu-143. Sum spectra in coincidence with single, double, and triple gates on SD transitions were produced to search for previously reported two-step links between the superdeformed and the near-yrast ND

How can we use computers to enhance learning?

How do we, in a basic statistics course, create a learning environment where the computer is a natural tool? Different aspects to be considered are the students' feeling of ownership and the importance of integrating the computer exercises in the course syllabus. The teacher has different tools to achieve a computer-supported learning environment and we give some examples. The actual design of the

The body size of wild boar during the Mesolithic in southern Scandinavia

In order to study the body size of wild boar Sits scrofa Linnaeus, 1758 during the Boreal and Atlantic Chronozones in southern Scandinavia, 12 measurements of teeth and bones from 32 Mesolithic sites from Scania (Sweden) and Zealand and Jutland (Denmark) were analysed. The osteometric analysis revealed that the body size of wild boar from Scania did not change during the period. The results indica

Sensor and biosensor based on Prussian Blue modified gold and platinum screen printed electrodes

Gold (Au) and platinum (Pt) screen-printed electrodes were modified with Prussian Blue (PB) for the development of amperometric sensors selective for hydrogen peroxide detection. The sensors exhibited sensitivities towards H2O2 equal to 2 A M−1 cm−2 for Au and 1 A M−1 cm−2 for Pt electrodes. The sensors were also employed as the basis for construction of glucose biosensors through further modifica

Haplotype-based analysis of common variation in the acetyl-CoA carboxyiase alpha gene and breast cancer risk: A case-control study nested within the European prospective investigation into cancer and nutrition

A key fatty acid synthesis enzyme, acetyl-CoA carboxylase alpha(ACC-alpha), has been shown to be highly expressed in human breast cancer and other tumor types and also to specifically interact with the protein coded by one of two major breast cancer susceptibility genes BRCA1. We used a comprehensive haplotype analysis to examine the contribution of the ACC-alpha common genetic variation (allele f

Early urinary changes in Tamm-Horsfall protein and epidermal growth factor in diabetic children

Both glomerular and tubular markers have been used to follow diabetic nephropathy. However, neither albumin nor proximal tubular markers have proven useful in prepubertal diabetes. Hence we studied two markers derived from the distal tubular cells, Tamm-Horsfall protein (THP) and epidermal growth factor (EGF), The urinary excretion of THP and EGF was examined in samples obtained during the first 2

Self-esteem in persons with schizophrenia. A Nordic multicentre study

Background: Deinstitutionalisation has led to many people with serious mental illness spending most of their time outside psychiatric institutions. Not much is known about their subjective life. The paper presents the results of analysis of self-esteem in a group of non-institutionalised people with schizophrenia. Methods: Interviews were conducted with random samples of people with schizophrenia
