A proposed mechanism of tenderising post-rigor beef using high pressure-heat treatment

Tenderness of beef M. Sternomandibularis was tough when cooked from both raw, and when previously heated (60 degrees C, 20 min), whereas a significant improvement in tenderness was achieved when pressure-heat (P-H) treated Muscle (200 MPa, 60 degrees C, 20 min) was cooked. In order to determine the mechanism for this improvement, connective tissue, myofibrillar and sarcoplasmic proteins, were sepa

Experimental determination of deposition of diesel exhaust particles in the human respiratory tract

Diesel emissions are a major contributor to combustion-generated airborne ambient particles. To understand the role of diesel particulate emissions on health effects, it is important to predict the actual particulate dose deposited in the human respiratory tract, with respect to number, surface area and mass. This is complicated by the agglomerate nature of some of these particles. In this study t

Towards smart self-assembly of colloidal silica particles through diblock copolymer crystallization

An innovative associative strategy, crystallization-driven self-assembly, is discussed for hybrid inorganicorganic materials. We report the use of a semicrystalline poly(butadiene)-b-poly(ethylene oxide)(PB-b-PEO) diblock copolymer (BCP) that self-assembles with silica nanoparticles (NPs) in a selective solvent. In ethanol, at 60 degrees C, that is above the melting temperature T-m of the PEO bloc

Prefermentation improves xylose utilization in simultaneous saccharification and co-fermentation of pretreated spruce.

ABSTRACT: BACKGROUND: Simultaneous saccharification and fermentation (SSF) is a promising process option for ethanol production from lignocellulosic materials. However, both the overall ethanol yield and the final ethanol concentration in the fermentation broth must be high. Hence, almost complete conversion of both hexoses and pentoses must be achieved in SSF at a high solid content. A principal

The Genetic Structure of the Swedish Population

Patterns of genetic diversity have previously been shown to mirror geography on a global scale and within continents and individual countries. Using genome-wide SNP data on 5174 Swedes with extensive geographical coverage, we analyzed the genetic structure of the Swedish population. We observed strong differences between the far northern counties and the remaining counties. The population of Dalar

The association between socioeconomic position, use of revascularization procedures and five-year survival after recovery from acute myocardial infarction

Background: Patients living under better socioeconomic circumstances often receive more active treatments after an acute myocardial infarction ( AMI) compared to less affluent patients. However, most previous studies were performed in countries with less comprehensive coverage for medical services. In this Swedish nation- wide longitudinal study we wanted to evaluate long- term survival after AMI

Market driving multinationals and their global sourcing network

Purpose - The purpose of this paper is to explore how a global supplier network can support and contribute to a market driving strategy. Theoretically, the paper contributes by integrating the market driving strategy and the network approach. IKEA is considered one of the leading market driving firms. The paper studies its activities in establishing supplier networks in Russia and Poland. Design/m

Coupling of plasmonic nanoparticles to their environments in the context of van der Waals-Casimir interactions

We present experiments in which the interaction of a single gold nanoparticle with glass substrates or with another gold particle can be tuned by in situ control of their separations using scanning probe technology. We record the plasmon resonances of the coupled systems as a function of the polarization of the incident field and the particle position. The distinct spectral changes of the scattere

Effect of A/B-site substitution on oxygen production performance of strontium cobalt based perovskites for CO2 capture application

Oxy-fuel combustion is one of the proposed technologies which have the potential to achieve zero CO2 emission. Strontium cobalt based perovskite oxygen carriers are promising materials for air separation with a high selectively for oxygen. And these perovskites can produce an oxygen enriched carbon dioxide stream for an oxy-fuel combustion process. The relatively low oxygen production yield may be

Waning predictive value of serum adiponectin for fracture risk in elderly men: MrOS Sweden

Serum adiponectin is a risk factor for fracture. The predictive value attenuates with time in elderly men so that its use for the risk assessment in the long term is questionable. The study underlines the importance of testing the long-term stability of potential risk factors. High serum adiponectin is associated with an increased risk of fracture in elderly men. The aim of the present study was t

Lipase-catalyzed synthesis and characterization of 1-butanoyl-2-palmitoyl phosphatidylcholine, a potential lipidic prodrug of butyric acid.

1-Butanoyl-2-palmitoyl phosphatidylcholine was synthesized from dipalmitoylphosphatidylcholine (DPPC) and butyric acid using a lipase catalyzed transesterification in toluene at controlled water activity. A high fatty acid concentration and low water activity were essential for the enzymatic synthesis. The transesterification resulted in 97.3% incorporation of butyric acid in the sn-1 position wit

Nature and Culture in Prehistoric Amazonia : Using G.I.S. to reconstruct ancient ethnogenetic processes from archaeology, linguistics, geography, and ethnohistory

Popular AbstractAvhandlingen undersöker sociokulturell och lingvistisk utveckling i det förkolumbianska Amazonområdet, med särskild fokus på perioden 500 f.Kr. till år 1500. Genom att sammanföra och analysera data från arkeologi, lingvistik, etnohistoria, etnografi och geografi i ett Geografiskt Informationssystem (G.I.S.) syntetiserar den stora mängder empiriska data från flera fält för att underThis thesis investigates the socio-cultural and linguistic development of pre-Columbian Amazonia, with a particular focus on the period between 500 BC and AD 1500. In assembling and analyzing data from archaeology, linguistics, ethnohistory, ethnography, and geography in a Geographical Information System (G.I.S.), it synthesizes large amounts of empirical data from several fields to facilitate lon

Access to highly active antiretroviral therapy (HAART) in the WHO European Region 2003-2005

Aims: To assess changes in access to highly active antiretroviral therapy (HAART) between the end of 2002 and the end of 2005, and to review the capacity for further HAART scale-up in the then 52 Member States of the WHO European Region. Methods: Analysis of data from four surveys evaluating access to HAART, supplemented by regional estimates of the number of people receiving HAART. Changes in acc

Binding of vitronectin and Factor H to Hic contributes to immune evasion of Streptococcus pneumoniae serotype 3.

Streptococcus pneumoniae serotype 3 strains are highly resistant to opsonophagocytosis due to recruitment of the complement inhibitor Factor H via Hic, a member of the pneumococcal surface protein C (PspC) family. In this study, we demonstrated that Hic also interacts with vitronectin, a fluid-phase regulator involved in haemostasis, angiogenesis, and the terminal complement cascade as well as a c
