Open-loop optimal control of batch chromatographic separation processes using direct collocation

This contribution presents a novel model-based methodology for open-loop optimal control of batch high-pressure liquid chromatographic (HPLC) separation processes. The framework allows for simultaneous optimization of target component recovery yield and production rate with respect to a parameterization of the input elution trajectory and fractionating interval endpoints. The proposed methodology

Comparing Lagrangian and Eulerian models for CO 2 transport-a step towards Bayesian inverse modeling using WRF/STILT-VPRM

We present simulations of atmospheric CO 2 concentrations provided by two modeling systems, run at high spatial resolution: the Eulerian-based Weather Research Forecasting (WRF) model and the Lagrangian-based Stochastic Time-Inverted Lagrangian Transport (STILT) model, both of which are coupled to a diagnostic biospheric model, the Vegetation Photosynthesis and Respiration Model (VPRM). The consis

Toward assimilation of observation-derived mixing heights to improve atmospheric tracer transport models

Common transport models use the mixing height (MH) to determine turbulent coefficients and to obtain tracer concentrations in the planetary boundary layer (PBL). We conducted a pseudo data experiment to elucidate the impact of assimilating MHs to improve CO2 transport within the Stochastic Time-Inverted Lagrangian Transport model (STILT). Transport of CO2 was simulated for August 2006 with a recep

The regional aerosol-climate model REMO-HAM

REMO-HAM is a new regional aerosol-climate model. It is based on the REMO regional climate model and includes most of the major aerosol processes. The structure for aerosol is similar to the global aerosol-climate model ECHAM5-HAM, for example the aerosol module HAM is coupled with a two-moment stratiform cloud scheme. On the other hand, REMO-HAM does not include an online coupled aerosol-radiatio

Konst och subjektskapande : neurodegenerativa nedsättningar och dialogbaserad konstpedagogik

Sedan 2007 har ett flertal konst- och forskningsprojekt genomförts där personer som drabbats av neurodegenerativa nedsättningar deltagit i samtal om konst. Den forskning som hittills undersökt projektens betydelse har fokuserat på den fysiska och psykiska verkan konstvisningarna haft för deltagarna, baserat på intervjuer, mätningar och enkätundersökningar. I den här texten väljer vi att undersöka

Könsinkluderande språk i nästa svenska bibelöversättning

Gender-inclusive language has been consciously applied in almost all significant English Bible translations over the last thirty years. It has only recently been introduced into Swedish Bible translation practices, however, with the test translation of Luke 9:51–19:28 and Galatians issued by the Swedish Bible Society. This fact signals that the next Swedish Bible translation will implement gender-

On the origin of B cells. Elucidating the Role of Tyrosine Kinase Receptors in B Cell Development.

B cells are essential cells that are part of the adaptive immune system with the capacity to produce antibodies against exogenous antigens. These cells are produced through a process called hematopoiesis, tightly regulated by extrinsic and intrinsic factors. Among these, tyrosine kinase receptors and their cytokines have been shown to have an important role in adult lymphopoiesis regulation. Howev

Childhood body mass index in adolescent-onset anorexia nervosa

OBJECTIVE: Although weight history is relevant in predicting eating disorder symptom severity, little is known about its role in the etiology of anorexia nervosa (AN). This study aimed to determine whether BMI or BMI trajectory differed between individuals who later developed adolescent-onset AN and a comparison group of HCs between school grades 1 through 6.METHOD: This study was based on longitu

Community-based tourism in practice : Evidence from three coastal communities in Bohuslan, Sweden

Local involvement in tourism development is defined as a key issue for sustainable tourism, however it is often questioned and less seldom implemented in reality. Reasons behind this condition are lack of knowledge and practical experience on community-based tourism as a bottom-up approach. In this paper it is argued that local involvement in tourism development is both a democratic right and a st

Tracking the intrusion of unwanted memories into awareness with event-related potentials

Involuntary retrieval of unwanted memories is a common symptom in several clinical disorders, including post-traumatic stress disorder. With an aim to track the temporal dynamics of such memory intrusions, we recorded electrophysiological measures of brain activity while participants engaged in a Think/No-Think task. We presented the left hand word (the cue) of previously encoded word pairs in gre
