Laboratory experiments offer one way to introduce more realism into the education of automatic control. This paper describes a control laboratory and a sequence of experiments performed in the basic automatic control courses at Lund Institute of Technology. The laboratory is based on level control of two cascaded tanks. An Apple II computer is used to implement control laws and to provide graphics
Osteoarthritis (OA) is a major health burden among the middle aged and elderly. Partial meniscectomy, the most common orthopedic surgical intervention, is recognized as a strong risk factor for knee OA. Loss of the main meniscal functions, load distribution and shock absorption, are often critical steps in knee OA development. This review outlines the concept of a dual relationship between menisce
The purpose of this study was to investigate how different service delivery systems for assistive devices were associated with the service delivery process (SDP) and user satisfaction in two national contexts when electric powered scooters were provided. Method: The study had a follow-up design based on a consecutive inclusion of 50 Danish and 86 Norwegian adults as they were about to be provided
Humanistic and positive psychology have had a contentious past. Initially, positive psychology researchers have distanced themselves from humanistic psychology, proceeding to build an array of differentiated constructs relevant to an empirical study of well-being. Twenty years on, it is now generally acknowledged that humanistic psychology is the theoretical predecessor of positive psychology in t
En två-kolonn MCSGP process för upprening av Liraglutid genomfördes i laboratorieskala. Den här processen är inte en kommersiell uppreningsprocess, utan att den är ett modellsystem med en realistisk peptidblandning och med en icke-kommersiell harts. Först modellerades processen med en konvektiv dispersiv modell för att beskriva koncentrationen genom kolonnen och den steriska massaktionsmodellen föA twin-column MCSGP process for the purification of Liraglutide was implemented at lab scale. This process is not a commercial separation step, but it is a model system with a realistic peptide mixture and with a non-commercial resin. First, the process was modeled using a convective dispersive model to describe the concentration along the column and the steric mass action model to describe the ad
This thesis examines the role of public servants in official development assistance (ODA), a form of foreign aid administered by states. While research on foreign aid highlights its potential to improve living conditions, it also reveals issues of ineffectiveness and overconfidence within the aid sector. Moreover, certain forms of foreign aid continued and can still continue to perpetuate colonial
Protein homeostasis in cells, proteostasis, is maintained through several integrated processes and pathways and its dysregulation may mediate pathology in many diseases including Duchenne muscular dystrophy (DMD). Oxidative stress, heat shock proteins, endoplasmic reticulum (ER) stress and its response, i.e. unfolded protein response (UPR), play key roles in proteostasis but their involvement in t
It is well known that the testicles are among the most radiosensitive tissue, and constitute an important critical target for both external and internal radiation during diagnostic and therapeutic use of radionuclides. In systemic radionuclide therapy where very high activities are administered, the testis may become a dose-limiting organ; often with a complex, non-uniform activity distribution an
Popular Abstract in Swedish Sammanfattning på svenska Muskelvävnad är specialiserad på att förkorta sig och utveckla kraft. Glatt muskulatur finns i blodkärlens väggar, i urinvägarna, i luftvägarna samt i mag-tarmkanalen, och är viktig för dessa organs funktion. Namnet "glatt" (smooth) härrör från muskulaturens utseende i mikroskop. Den glatta muskulaturen ser slät ut, i motsats till det "randiga"Smooth muscle is characterised by high tension economy, low shortening velocity and regulation mainly by myosin light chain (MLC) phosphorylation. The aim of this study was to investigate regulation of force and maximal shortening velocity (Vmax) in smooth muscle. In intact muscle, activated with depolarisation, inhibition of force and rise in intracellular [Ca2+] ([Ca2+]i) by 2,3-butanedione mono
