Purification of biopharmaceuticals has shifted toward continuous and integrated processes, in turn bringing along a need for monitoring and control to maintain a desired separation between the target pharmaceutical and any impurities it may carry. In this study, a cycle-to-cycle control of the retention volumes of two compounds in a chromatographic, ion exchange purification step was developed, al

Background: Severe diminished foot somatosensation, for example, caused by neuropathies and advanced aging, contributes to balance deficits and increased fall risk. However, little is known about somatosensory impairment and functional and subjective balance problems in relatively healthy elderly. Method: Vibration perception thresholds (VPTs) were assessed with a biothesiometer and tactile pressu

Model predictive control (MPC) is applied to a physical pendulum system consisting of a pendulum and a cart. The objective of the MPC controller is to steer the system towards precomputed, time-optimal feedforward trajectories that move the system from one stationary point to another. The sample time of the controller sets hard limitations on the execution time of the optimization algorithm in the

As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. But as more DG is installed, it can lead to issues in the DN such as overloading and overvoltage when production is

The laboratory consists of a XenX x-ray irradiator (XStrahl) for experimental radiobiology, with supporting equipment for cell culture applications, such as laminar flow cabinets, CO2 incubators, and a hypoxia workstation. The XenX unit is designed as a radiotherapy machine in miniature. It consists of a 225 kV x-ray source, mounted on a rotatable gantry allowing irradiation of specimens from all

Abstract in UndeterminedJavaScript has gone from being a mechanism for providing dynamic web pages to an important component of many web applications. Currently one of the most popular type of web applications is so-called social networks, e.g., Facebook, Twitter, and MySpace. However, the workload and execution behavior of JavaScript in this context have not been fully explored or understood.In t

The function of a paper machine is to form the paper sheet and remove the water from the sheet. A modern paper machine is divided into three main parts, the wire section, the press section, and the dryer section. Although the dryer section is only responsible for removing less than 1% of the water volume in the original stock to the head box, this is the part of the paper machine that, by far, con

Aim: To evaluate the indications for, and outcome, of appendicostomy for patients with Hirschsprungs disease (HD) who underwent transanal endorectal pull-through (TERPT). Method: Children with HD > 4 years old who received an appendicostomy between 2005 and 2011 at a tertiary pediatric surgery center were included. Pre- and post-appendicostomy bowel function was evaluated by a bowel function scor

Diabetes mellitus is one of the most common comorbidities in palliative care. Yet, the optimal handling of diabetes mellitus in dying patients is debated. This review aims to discuss comprehensively the scientific basis as of today for diabetes mellitus management decisions in end-of-life (EOL) care.

Although the visual flight control strategies of flying insects have evolved to cope with the complexity of the natural world, studies investigating this behaviour have typically been performed indoors using simplified two-dimensional artificial visual stimuli. How well do the results from these studies reflect the natural behaviour of flying insects considering the radical differences in contrast
