Evaluation of Steam-Treated Giant Bamboo for Production of Fermentable Sugars

Giant bamboo plantations are currently being established in the Southern Africa region and can be considered as potential lignocellulosic feedstock for the production of second generation bioethanol. In this study, giant bamboo internodal material was subjected to sulphur dioxide (SO2) impregnated steam pretreatment prior to enzymatic hydrolysis. The effect of temperature, residence time, and acid

Staff's Collaborative work process with an adolescent boy with autism and intellectual disability in a community-based sheltered housing

The aim of this single-case study was to describe the staff's collaborative work process for a period of 3.5 years caring for an adolescent boy with autism and intellectual disabilities living in an apartment of his own together with his caregivers. The longitudinal data included the staff's (two men and two women) common open diary, repeated individual interviews and focus group interviews. Detai

Transport of a hyaluronan-binding protein in brain tissue

Hyaluronan is an unsulfated linear glycosaminoglycan with the ability to nucleate extracellular matrices by the formation of aggregates with lecticans. These matrices are essential during development of the central nervous system. In the prospective white matter of the developing brain hyaluronan is organized into fiber-like structures according to confocal microscopy of fixed slices which may gui

III-V Nanowire Complementary Metal-Oxide Semiconductor Transistors Monolithically Integrated on Si

III-V semiconductors have attractive transport properties suitable for low-power, high-speed complementary metal oxide-semiconductor (CMOS) implementation, but major challenges related to cointegration of III-V n- and p-type metal-oxide-semiconductor field-effect transistors (MOSFETs) on low-cost Si substrates have so far hindered their use for large scale logic circuits. By using a novel approach

Postgång på växlande villkor : det svenska postväsendets organisation under stormaktstiden

Popular Abstract in Swedish Det svenska postväsendet grundades 1636 genom en kunglig förordning om postbud. Under det följande århundradet byggdes postnätet ut över riket och alla större städer fick postkontor. Från början sköttes verksamheten av staten, men under stormaktstiden förändrades organisationen flera gånger och lades vid ett par tillfällen ut på entreprenad. I doktorsavhandlingen PostgåThis dissertation investigates the Swedish postal service, focusing on its organization from approximately 1600 to 1720. The purpose of the study is to explain why the Swedish state, at different points of time, chose one form of postal organization over another. The principle question of the dissertation has been: How was the Swedish postal service organized during the 1600s, what were the forms

The protonation state of small carboxylic acids at the water surface from photoelectron spectroscopy

We report highly surface sensitive core-level photoelectron spectra of small carboxylic acids (formic, acetic and butyric acid) and their respective carboxylate conjugate base forms (formate, acetate and butyrate) in aqueous solution. The relative surface propensity of the carboxylic acids and carboxylates is obtained by monitoring their respective C1s signal intensities from a solution in which t

The solids-flux theory - Confirmation and extension by using partial differential equations.

The solids-flux theory has been used for half a century as a tool for estimating concentration and fluxes in the design and operation of secondary settling tanks during stationary conditions. The flux theory means that the conservation of mass is used in one dimension together with the batch-settling flux function according to the Kynch assumption. The flux theory results correspond to stationary

Work environment perceptions following relocation to open-plan offices: A twelve-month longitudinal study

BACKGROUND: A workplace's design can have various positive or negative effects on the employees and since the 1970s the advantages and disadvantages of open-plan offices have been discussed. OBJECTIVE: The aim of this study was to investigate perceived health, work environment and self-estimated productivity one month before and at three, six and twelve months after relocation from individual offi

Partial Enumeration and Curvature Regularization

Energies with high-order non-submodular interactions have been shown to be very useful in vision due to their high modeling power. Optimization of such energies, however, is generally NP-hard. A naive approach that works for small problem instances is exhaustive search, that is, enumera- tion of all possible labelings of the underlying graph. We propose a general minimization approach for large gr

Neutron shell structure and deformation in neutron-drip-line nuclei

Neutron shell structure and the resulting possible deformation in the neighborhood of neutron-drip-line nuclei are systematically discussed, based on both bound and resonant neutron one-particle energies obtained from spherical and deformed Woods-Saxon potentials. Owing to the unique behavior of weakly bound and resonant neutron one-particle levels with smaller orbital angular momenta l, a systema

Modeling mesoscopic solidification using dissipative particle dynamics

Dissipative particle dynamics with energy conversion (DPDe) is a simulation technique that has been used to model thermal transport characteristics and heat transfer at mesoscale. This study shows further development of the DPDe method capturing solid/liquid phase-change phenomena and its application to water freezing in a parallel-plate straight channel. In this work, the weighting functions of t
