This paper presents an environmental system study of the production of propionic acid in a biorefinery system based on agricultural by-products. Here, propionic acid is produced by fermentation of glycerol, a by-product from biodiesel production, as carbon source and potato juice, a by-product from starch production, as nitrogen source. Biomass-based propionic acid leads to a greenhouse gas reduct

Head and neck squamous cell carcinoma (HNSCC) is known to cause substantial immunosuppression. The present study was designed to characterize blood leukocyte activation in HNSCC and to investigate if the individual activation pattern could be related to tumor progress and survival. The leukocyte activation profile of HNSCC patients and healthy controls was assessed with flow cytometry. HNSCC patie

Modeling of combustion engines using computational fluid dynamics (CFD), to investigate and improve performance of biodiesel combustion, calls for development of small and efficient chemical kinetics mechanisms that accurately represent ignition and flame propagation of renewable fuels. In this work, a semi-global approach is used to develop a mechanism suitable for three-dimensional CFD of fatty

Syftet med vår uppsats var att utreda behovet av multilingvistisk kundservice på den svenska marknaden samt att studera hur företag hanterar kunder med icke-svensk bakgrund. Vårt sekundära syfte vara att undersöka affärsmöjligheter för ett multilingvistiskt call center. Uppsatsens teoretiska ramverk består av kundbaserad teori, där teorier kring Customer Relation Management, kundservice, call cent

The climate is changing, something that many scientists correlate to increased emissions of greenhouse gases. The effluent that is considered to have the highest impact on global warming is carbon dioxide, when effect and quantity are taken into account. Most projections however, show that the effect is reversible if the amount of carbon dioxide emissions discharged to the atmosphere is decreased.

It has been proposed that hyaluronan-binding proteoglycans play an important role as guiding cues during neural crest (NC) cell migration, but their precise function has not been elucidated. In this study, we examine the distribution, structure and putative role of the two major hyaluronan-binding proteoglycans, PG-M/versicans and aggrecan, during the course of avian NC development. PG-M/versicans

Germ layer formation and primary axis development rely on Fibroblast growth factors (FGFs). In Xenopus, the secreted serine protease HtrA1 induces mesoderm and posterior trunk/tail structures by facilitating the spread of FGF signals. Here, we show that the serpin Protease nexin-1 (PN1) is transcriptionally activated by FGF signals, suppresses mesoderm and promotes head development in mRNA-injecte

For the production of basic materials a deep decarbonization fundamentally requires the development of new process technologies. However, the climate policies currently adopted in G8 countries mainly reward incremental improvements and preserve industrial structures rather than induce innovation and preparations for a low-carbon transition. The current policy approach is motivated by fear of carbo

The transition towards low-carbon energy systems undeniably requires a strong scale-up in the diffusion of renewable energy technologies globally. Given its theoretical and techno-economic potential, solar photovoltaics (PV) is considered an important option. The envisioned scale-up of the use of solar PV, however, requires an in-depth and system-oriented perspective on structures and processes re

Pseudogenes, nonfunctional copies of genes, evolve fast due the lack of evolutionary pressures and thus appear in several different forms. PseudoGeneQuest is an online tool to search the human genome for a given query sequence and to identify different types of pseudogenes as well as novel genes and gene fragments.

Fuel-cycle emissions of carbon dioxide (CO2) carbon oxide (CO), nitrogen oxides (NOx), sulphur dioxide (SO2), hydrocarbons (HC), methane (CH4), and particles are analysed from a life-cycle perspective for different biogas systems based oil six different raw materials. The gas is produced in large- or farm-scale biogas plants, and is used in boilers for heat production, in turbines for co-generatio

The molecular conservation of a surface-exposed lipoprotein, protein D, of Haemophilus influenzae was studied by cloning and sequencing of the gene encoding protein D from three encapsulated type b strains and three nontypeable strains of H. influenzae. These nucleotide sequences were analyzed with previously reported sequences from one type b strain and one nontypeable strain. The nucleotide sequ

Lactic acid bacteria constitute a diverse group of industrially significant, safe microorganisms that are primarily used as starter cultures and probiotics, and are also being developed as production systems in industrial biotechnology for biocatalysis and transformation of renewable feedstocks to commodity- and high-value chemicals, and health products. Development of strains, which was initially

The production and use of transportation fuels can lead to sustainability impacts. Assessing them simultaneously in a holistic way is a challenge. This paper examines methodology for assessing the sustainability performance of products in a more integrated way, including a broad range of social impacts. Life Cycle Sustainability Assessment (LCSA) methodology is applied for this assessment. LSCA of

Novel soil remediation equipment based on electro-kinetic geosynthetics (EKG) was developed for in situ isolation of metals from paddy soil. Two mutually independent field plot experiments A and B (with and without electric current applied) were conducted. After saturation using ferric chloride (FeCl3) and calcium chloride (CaCl2), soil water drainage capacity, soil cadmium (Cd) removal performanc

Context: The biological mechanism for the association between sleep duration and incident diabetes mellitus (DM) is unclear. Sleep duration and Caspase-8, a marker of apoptotic activity, have both been implicated in beta cell function.Objective: To investigate the associations between sleep duration and plasma Caspase-8, and incident DM, respectively.Design: Prospective cohort study.Setting: The M

Accurate prediction on the pressurized discharge performance is significant to the safety operation of cryogenic propellant system. In the present study, a two-dimensional numerical model is established to simulate the fuel outflow with high-temperature gas injection. Both the environmental heat invasion and interfacial phase change are detailedly considered. The volume of fluid method is used to

Wind energy is a rapidly growing field of renewable energy, and as such, intensive scientific and societal interest has been already attracted. Research on wind turbine structures has been mostly focused on the structural analysis, design and/or assessment of wind turbines mainly against normal (environmental) exposures while, so far, only marginal attention has been spent on considering extreme n
