The cytotoxic eosinophil cationic protein (ECP) has ribonuclease activity

The eosinophil cationic protein (ECP) is a specific cytotoxic constituent of granules. In this work we demonstrated that ECP has a ribonuclease activity. Purified ECP was resolved by ion exchange chromatography into subfractions, which all showed ribonuclease activity. Another eosinophil granule protein, EPX, identical with eosinophil-derived neurotoxin (EDN) had a 125-fold higher RNase activity t

Construction of a FrameNet Labeler for Swedish Text

We describe the implementation of a FrameNet-based semantic role labeling system for Swedish text. To train the system, we used a semantically annotated corpus that was produced by projection across parallel corpora. As part of the system, we developed two frame element bracketing algorithms that are suitable when no robust constituent parsers are available. Apart from being the first such system

Congestion Control in Packet Switching Computer Communication Networks

The objective of this research is in general to develop analytic tools for the performance study of computer networks, and is in particular motivated by a need to understand how restricted buffer sharing policies can be used for congestion control in the nodes of a packet switching computer communication network. Models of a single packet switching node with finite storage and restricted buffer s

A Study of Indoor Aerosol Size Distribution and Attachment of Radon Daughters

The particle size distribution in 11 different dwellings was studied during 5-7 days, samples being taken every 15 min. Large variation in the aerosol concentration has been found. Also the size distribution of the aerosol varies depending on the level of activity in the home, e.g. smoking and cooking. The average area median diameter found in the dwellings was 0.2 ,am. A technique for the measure

Timing Problems in Real-Time Systems

The article describes and analyzes how random time delays effect control loops that are closed over a communication network. Analysis as well as LQG-design are presented. The optimal controller is using timestamps to determine the timedelay between the sensor and the controller.

Poly (3-hydroxybutyrate) from a moderate halophile: production and modification for new applications

Popular Abstract in English Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence repPolyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients.

Skyll inte hat och ondska på nätet

Det är inte ett nätproblem vi har på halsen, det är mer världsligt än så. Men det betyder samtidigt att vi har många av lösningarna närmare än vi tror. Istället för att se allt som rör internet som svårt, läskigt eller rentav magiskt har vi redan det mesta som behövs nära till hands.
