Polyamine-Dependent Early Cellular Signals and Cell Proliferation

When a resting cell is awakened to enter the cell cycle by mitogenic stimulation, a complex molecular machinery involving positive and negative regulation of cell-cycle progression is initiated. Part of the machinery is quite well-known. It involves receptors of various kinds, protein interactions, phosphorylation reactions, and molecular cascades carrying the signal to enter the cell cycle from t

Dual band ISM 2.4 GHz and 5 GHz finger antenna

A dual band antenna for two ISM bands at 2.4 GHz and 5 GHz has been evaluated. The antenna structure derives its advantage by deploying several radiators as fingers spreading from a single feeding point. Each radiator functions as both a half-wave and a quarter-wave radiator. Arranging them in parallel matches the half-wave resonance to 50 W. By carefully selecting the angle to ground plane and us

LDPC Convolutional Codes Based on Braided Convolutional Codes

We introduce and analyze new constructions of LDPC convolutional codes and their tail-biting versions which are obtained from braided convolutional codes. The basic ideas behind the encoding and decoding architectures for these codes are presented. Additionally, asymptotic results concerning the iterative thresholds are shown for different ensembles. Finally, we evaluate the bit error rate perform

Sesquiterpene synthases in Artemisia annua: Cloning, Expression, and Characterisation of the Recombinant Enzymes

Popular Abstract in Swedish Extrakt från växten Artemisia annua har dokumenterats för sina anti-malaria egenskaper. Substansen är en mycket effektiv medicin mot malaria och hjälper även mot de former där multi-resistens utvecklats.1979 presenterades strukturen på den aktiva substansen. Den benämns artemisinin och är uppbygd av femton kol innehållandes en peroxid-brygga (två syre kopplade till varaPlants produce a multitude of different compounds that may have biotic effects. Artemisia annua, produces a compound used as a drug against multi-drug-resistant strains of Plasmodium falciparum, the parasite causing malaria. The compound, artemisinin, is a sesquiterpene and is an essential component for the production of artemisinin drugs against malaria. In a first critical step of the biosynthes

Flow and noise investigations of a separate flow exhaust system

A major component of aircraft noise is the jet noise created by the high velocity hot stream exhausting from a jet engine, interacting with itself and with the surrounding cold air. In the present paper the flow and acoustic fields that are generated by two coaxial jets are considered. Numerically, the problem is divided into a flow related part (Navier-Stokes system of equation) and an acoustic p

“Jag är Josef, er bror, som ni sålde till Egypten”

This article surveys the history of interpretation of Joseph / Yusuf in the Jewish, Christian and Muslim traditions, focusing on the gender perspective in Jewish sources, typology in the Christian tradition, and the theocentric perspective in Muslim texts.

Structure of long-term home and institutional care systems in Europe

The aim of this part of the RightTimePlaceCare study (WP2) was to describe and analyse the European health, social care and welfare systems, advocacy and informal caregiver support systems for patients with dementia. The description and analyses covers the continuum of care from diagnosis, informal care, contributions from civic society, public home care and the intermediate forms of care, to the

Krakel Spektakel, hör hur det låter! Studier i Lennart Hellsings språkvärld

Popular Abstract in Swedish Undersökningen syftar till att klargöra hur överföringen av hellsingtexter till barnpubliken har en motsvarighet i texternas form och hur detta bidrar till att forma diktarens poetiska universum. Texterna står i centrum och perspektivet är brett. Eftersom barnlitteratur är en litterär sidoström behövs andra teorier och metoder än för annan litteratur. Jag fokuserar den This thesis deals with Lennart Hellsing's works, and especially his texts for small children, from 1945 to 2000. In an introductory survey the oral transmission of literature is discussed in relation to orality and literacy. The presupposition is that there are similarities between oral culture and texts for the very young. Hellsing's production is surveyed along with his position as a poet, his i

A process model for the design analysis clarification task

Many product development projects nowadays use computer-aided engineering systems in the analysis of product proposals. It is therefore important to appropriately integrate the analyses activities in the product development process. One important aspect of this integration is how to handle the initiation of the task: identifying the need, planning the task and its monitoring, and communicating it
