Ash is produced in combustion of biomass. Sonic part of this matter is called fly ash and is carried by the flow and causes not only air pollution and erosion, but also call affect the thermal radiation. The effects of fly ash particles oil the thermal radiation are considered ill this investigation. By analyzing sampled data in all electrostatic filter, a realistic particle size distribution is f

Popular Abstract in Swedish Hur gör bakterier för att komma undan immunförsvaret? Vi har studerat hur en vanligt förekommande bakterie, grupp A streptokocker, gör för att undvika kroppens immunförsvar vid infektion. Vi har upptäckt enzymer som bidrar till bakteriens förmåga att undvika immunförsvaret genom att avväpna antikroppar. De bakteriella enzymerna kan användas i bioteknisk industri och eveA majority of the proteins of the immune system are glycosylated and the glycans of IgG are essential for its functionality. Bacteria display enzymes that modulate the glycans of the immune system to weaken the host defense and favor bacterial survival. In this thesis we aimed at exploring bacterial modulation of host glycosylation in infection and to evaluate the usefulness of bacterial enzymes i

In this paper the PreAmplifier ShAper (PASA) for the Time Projection Chamber (TPC) of the ALICE experiment at LHC is presented. The ALICE TPC PASA is an ASIC that integrates 16 identical channels, each consisting of Charge Sensitive Amplifiers (CSA) followed by a Pole-Zero network, self-adaptive bias network, two second-order bridged-T filters, two non-inverting level shifters and a start-up circu

The development of therapeutic and diagnostic antibodies is a rapidly growing field of research, being the fastest expanding group of products on the pharmaceutical market, and appropriate quality controls are crucial for their application. We have identified and characterized the serine protease termed BspK (Bdellovibrio serine protease K) from Bdellovibrio bacteriovorus and here show its activit

In the equation for thermal energy output from a flat-plate solar collector (written as a function of the collector mean heat carrier temperature), both the gain and the loss terms are multiplied by the collector efficiency factor, F'. For a concentrating collector with an uneven (non-uniform) irradiation on the absorber, the efficiency factor for the gain term, here called the optical efficiency

The M protein of Streptococcus pyogenes is a major bacterial virulence factor that confers resistance to phagocytosis. To analyze how M protein allows evasion of phagocytosis, we used the M22 protein, which has features typical of many M proteins and has two well-characterized regions binding human plasma proteins: the hypervariable NH2-terminal region binds C4b-binding protein (C4BP), which inhib

The common human pathogen Streptococcus pyogenes is the causative agent of numerous mild and severe clinical conditions. It expresses a number of secreted or cell wall-anchored proteins that modulate the human immune system and facilitate colonization and spread of the pathogen in the human host. During S. pyogenes infections, human plasma leaks into the site of infection as a consequence of infl

Eosinophils participate in the inflammatory response seen in allergy and helminthic infestation. Their release of granule-bound cationic proteins may play a role in these diseases. Therefore, we investigated mechanisms involved in the release of eosinophil cationic protein (ECP). Serum-opsonized zymosan was phagocytosed by eosinophils, and ECP was released into the phagosomes as judged by immunoel

The M protein family of molecules in the group A streptococcus comprises a number of cell surface proteins that interact with the immune system of the host. One of the proteins in this family is the IgA receptor Arp4, which has C repeats similar to those that characterize the known M proteins. The streptococcal strain expressing Arp4 also expresses a second immunoglobulin-binding protein, Mrp4, wh

The nonobese diabetic (NOD) mouse spontaneously develops autoimmune-mediated diseases such as diabetes and Sjögren′s syndrome. To investigate whether NOD genes also promote autoimmune-mediatedarthritis we established a NOD strain with an MHC class II fragment containing the Aq class II gene predisposing for collagen induced arthritis (NOD.Q). However, this mouse was resistant to arthritis in contr

Abstract på spanskaUna de las fuentes más sólidas de nuevo conocimiento sobre las categorías tipológicas proviene de nuestro creciente entendimiento de las lenguas indígenas de América del Sur, una región que hasta hace poco ha estado significativamente subrepresentada en los estudios tipológicos. Este artículo ofrece un ejemplo a través de la investigación del número en nadëb, un miembro de la peOne of the most robust sources of fresh insights into typological categories comes from our growing knowledge of the indigenous languages of South America, a region that until recently has been significantly under-represented in typological studies. This paper offers a case in point through the investigation of number in Nadëb, a member of the small Naduhup family of the northwest Amazon, which re

This master thesis examines a space issue in compact living and results in a transformable chair that also can serve as a bench. A big part of the project is the complex and creative way for the designer to fi nd his form language. Th is report looks closer on compact living, furniture in general, the chair especially, trends, infl uences from the furniture industry, carpentry and related subjects

BACKGROUND: The overall incidence of colorectal carcinoma is declining in Western populations; however, single country series demonstrate an increase in young-onset (<50 years) colorectal carcinoma. OBJECTIVE: The purpose of this study was to determine whether the pattern of increasing incidence of young-onset colorectal carcinoma is consistent across 3 Western populations. DESIGN: This is a popul

Urban transport network is a social space in which agents interact with multiple artifacts –signs, speed bumps, bridges, other vehicles, etc.– As Latour states, the study of social spaces needs to be “materialized”, in this case, considering the material infrastructure that allows –or not– the fluid use of the system, as a fundamental part of the analysis of the transport phenomenon. From an agent
