Removal of UHT dairy fouling — An efficient cleaning process by optimizing the rate controlling alkaline cleaning step

A rigid mineral-based deposit, termed ultra-high temperature (UHT) fouling, is formed on heat exchanger surfaces during milk processing at 140 °C. The removal of this type of fouling is for the first time assessed using a laser triangulation sensor and a camera, to measure changes in the thickness and to visualize structural changes in the fouling in situ. The process was monitored during both the

High-density and targeted glycoproteomic profiling of serum proteins in pancreatic cancer and intraductal papillary mucinous neoplasm

Objective: Glycoproteomics is an emerging subfield of proteomics. Tumor-specific variations in protein glycosylation might be potential targets for the development of new cancer diagnostics. Here, we performed high-throughput screening and targeted verification of glycome alterations in serum samples from patients with pancreatic cancer and the precancerous lesion intraductal papillary mucinous ne

Intestinal metaplasia at the gastroesophageal junction is associated with gastroesophageal reflux but not with Helicobacter pylori infection

Objective: Studies of the etiology of intestinal metaplasia (IM) at a normal appearing gastroesophageal junction (GEJ) are conflicting as associations with both H. Pylori (HP) infection and gastroesophageal reflux has been reported. The aim of this study was to investigate whether IM at the GEJ is associated with gastroesophageal reflux or HP infection. Material and methods: Fifty asymptomatic vol

A framework for aggregating risk information across organisational levels—the case of Swedish municipalities

Performing risk assessments for hierarchical, multi-functional systems, such as a municipality, is an activity that requires input from a multitude of actors. In such systems risk assessments can be performed at many system levels and support different types of decisions. For issues that are constrained to a specific sub-system, such as a municipal department, decisions can be preferably taken at

Design optimization of the borehole system for a plus-Energy kindergarten in Oslo, Norway

This paper presents the case study of a newly constructed 1600 m2 kindergarten building in Oslo, Norway. The building has been designed within the framework of the Norwegian Research Council Project LowEx, which aims at engineering solutions to achieve a seasonal coefficient of performance (SCOP) of 6–10 for heating, a seasonal energy efficiency ratio (SEER) of 80–100 for cooling, and an 80% reduc

Contrasting critical infrastructure resilience from swedish infrastructure failure data

Critical technical infrastructures constitute the backbone of society by providing essential services to vital societal functions and the community at large, hence it is of essence that these are resilient. Critical infrastructures, e.g. power systems, telecommunication systems and railway systems, are designed and operated based on different philosophies of where to put the resilience emphasis, r

Testing the vertical and cyber-physical integration of cognitive robots in manufacturing

In recent years, cognitive robots have started to find their way into manufacturing halls. However, the full potential of these robots can only be exploited through (a) an integration of the robots with the Manufacturing Execution System (MES), (b) a new and simpler way of programming based on robot skills, automated task planning, and knowledge modeling, and (c) enabling the robots to function in

Cost effectiveness of implementing ESC guidelines for treatment of iron deficiency in heart failure in the Nordic countries

Objectives. Guidelines of the European Society of Cardiology (ESC) recommend that ferritin and transferrin saturation should be tested in chronic heart failure (HF) and state that iron treatment with ferric carboxymaltose should be considered in HF patients with iron deficiency to alleviate symptoms and improve exercise tolerance and quality of life. This study evaluates the cost effectiveness of

Tetrahydroxystilbene glucoside-induced relaxation of the superior mesenteric artery via both endothelium-dependent and endothelium-independent mechanisms

Tetrahydroxystilbene glucoside (TSG) is the main water-soluble component in Polygonum multiflorum Thunb, and it has many cardioprotective effects. Although TSG is able to relax blood vessels, its relaxation of rat superior mesenteric arteries and the underlying mechanism of this process are not clearly understood. The aim of the present study was to use in vivo and in vitro models to investigate t

Two theoretical strands of social capital, and total, cardiovascular, cancer and other mortality : A population-based prospective cohort study

The aim is to prospectively investigate both the “cohesion” and “network” perspectives of social capital in relation to total, cardiovascular (CVD), cancer and all other causes mortality. The 2008 public health survey in Scania was a postal questionnaire with three letters of reminder, and it was answered in the Autumn by 28,198 respondents (55% participation) aged 18–80 from a stratified random s

Mean arterial pressure during targeted temperature management and renal function after out-of-hospital cardiac arrest

Purpose: This study investigates the association between mean arterial pressure (MAP) and renal function after out-of-hospital cardiac arrest (OHCA). Materials and methods: Post-hoc analysis of 851 comatose OHCA-patients surviving >48 h included in the targeted temperature management (TTM)-trial. Results: Patients were stratified by mean MAP during TTM in the following groups; 80 mmHg (35%). Medi

Correlations for prediction of the bubble departure radius on smooth flat surface during nucleate pool boiling

Based on a modified force balance model, new correlations were proposed for the prediction of vapor bubble departure radius in saturated and subcooled pool boiling under atmospheric pressure. To predict the departure radius, the wall temperature and contact angle are two important input parameters. Instead of the static contact angle, the present correlations use the dynamic advancing contact angl

Is dissolved COD a suitable design parameter for ozone oxidation of organic micropollutants in wastewater?

Ozone oxidation of organic micropollutants in biologically treated wastewater was investigated in pilot-scale after a high- and a low loaded activated sludge process. Higher ozone doses were required to remove organic micropollutants in the effluent wastewater from the high loaded activated sludge process. Further comparison of the micropollutant removal was based on normalized ozone doses, expres

Physicochemical and structural properties of starch from five Andean crops grown in Bolivia

Three Andean grains - amaranth (Amaranthus caudatus), quinoa (Chenopodium quinoa), canihua (Chenopodium pallidicaulle) - and two Andean roots starches - achira (Canna indica), maca (Lepidium meyenii) - were studied. Physicochemical properties such as granule size, crystallinity, pasting properties among other as well as structural properties such as root-mean-square radius (rrms), weight-average m

Flow patterns and slug scaling of liquid-liquid flow in square microchannels

Liquid-liquid flow regimes in three square microchannels were visualized simultaneously both at the cross-shaped junction and in the microchannel “far” from the junction in order to reveal flow regime evolutions along the microchannel. At the inlet junction, three major flow regimes including tubing/threading, dripping and jetting were mapped using the aqueous capillary number versus the organic W

Stress-matrix-based formation scaling control

This paper investigates the formation scaling control problem for multi-agent systems by utilizing the stress matrix associated with a universally rigid framework. Compared with the existing results on formation scaling control, we consider a more challenging scenario where only one agent has the knowledge of the desired formation size. To cope with this constraint, we first propose a distributed

Partial safety factors for the anchorage capacity of corroded reinforcement bars in concrete

Many reinforced concrete bridges in Europe and around the world are damaged by reinforcement corrosion and the annual maintenance costs are enormous. It is therefore important to develop reliable methods to assess the structural capacity of corroded reinforced concrete structures and avoid unnecessary maintenance costs. Although there are advanced models for determining the load carrying capacity

Urban and agricultural soils : Conflicts and trade-offs in the optimization of ecosystem services

On-going human population growth and changing patterns of resource consumption are increasing global demand for ecosystem services, many of which are provided by soils. Some of these ecosystem services are linearly related to the surface area of pervious soil, whereas others show non-linear relationships, making ecosystem service optimization a complex task. As limited land availability creates co

The predatory mite Hypoaspis aculeifer is attracted to food of its fungivorous prey

To locate a prey a predator may rely on information originating from the habitat or the food of the prey, from the prey itself or its feeding activities. This study examines the origin of information used by the soil living predatory mite Hypoaspis aculeifer (Canestrini) when foraging for a fungivorous collembolan prey Folsomia f metaria (L.). Preference experiments were performed in Petri dishes,
