The problem of binding of microbial cells to an adsorbent matrix during in situ recovery of bioproducts from a fermentation broth has been addressed by shielding the adsorbent with a thin layer of a non-ionic polymer. Extractive bioconversion of lactic acid by integrating ion-exchange adsorption with the fermentation stage was studied. The effect of coating of the ion-exchanger with agarose on pro

This article is a response to Greenbank's (2006) The academic's role: the need for a re-evaluation? It is also a contribution to the ongoing debate about the need to develop a broader view of scholarship and the different activities related to it such as 'teaching', 'research' and 'service to the community'. Arguments related to current research are presented to enhance a deeper understanding and

The mixing process in a Lightnin Series 45 static mixer, 40 mm in diameter, has been investigated using computational fluid dynamics and the volume of fluid (VOF) method, a method developed for immiscible fluids but here used for miscible. The mixing process was investigated for two liquids that had viscosities ranging from 0.003 to 51.2 Pa s, and the volumetric flow rate proportion between the li

Drawing on Freire, this article elaborates on how pictures and artefacts benefit processes of 'prise de conscience' and 'conscientization' among those with powerful voices. Wor(l)d-making was unfolded in the Swedish think-and-do tank, 'the Smithy', emphasizing the intrinsically political nature of promoting 'societal entrepreneurship' (SE). New words for SE were formulated and a more inclusive wor

The activated sludge process (ASP), found in most wastewater treatment plants, consists basically of a biological reactor followed by a sedimentation tank, which has one inlet and two outlets. The purpose of the ASP is to reduce organic material and dissolved nutrients (substrate) in the incoming wastewater by means of activated sludge (microorganisms). The major part of the discharged flow throug

Slurries obtained from process streams in a starch-to-ethanol plant, Agroetanol AB in Norrköping, Sweden, were used to assess the potential increase in bioethanol yield if heat treatment followed by enzymatic hydrolysis were applied to the residual starch-free cellulose and hemicellulose fractions. The effects of different pretreatment conditions on flour (the raw material), the stream after sacch

The Homogeneous Charge Compression Ignition (HCCI) combustion progress has been characterized by means of high- speed fuel tracer Planar Laser-Induced Fluorescence (PLIF) combined with simultaneous chemiluminescence imaging. Imaging has been conducted using a high-speed laser and detector system. The system can acquire a sequence of eight images within less than one crank angle. The engine was run

The precipitation behavior, especially the early nucleation stages, of the industrial strip-cast Al3003 alloys was investigated by using transmission electron microscopy (TEM). An icosahedral quasicrystalline phase was found as secondary particles in these strip-cast alloys after heat treatment for a few seconds. Three different nucleation paths are proposed based on the TEM observations. They hav

A voltage reference has been implemented in a standard 0.35 μm CMOS process. A temperature coefficient of 12 ppm/°C is achieved in virtue of a complete suppression of the temperature dependence of the carrier mobility. The line sensitivity is 0.46 %/V and the maximum supply current, measured at 80°C, is 130 nA. The PSSR at 100 Hz and 10 MHz is -59 dB and -52 dB, respectively.
