Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

Popular Abstract in Swedish Marknaden för bestrukna tryckpapper har vuxit snabbare än för andra papperskvaliteter och förväntas göra så även i framtiden. Drivkraften bakom denna utveckling är kraven på bra färgåtergivning, framför allt inom reklamsektorn. Bestrukna papper blir en allt viktigare produkt för den svenska pappersindustrin men det är också ett område där konkurrensen och produktkraven This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. The seed latexes used were polystyrene, whose properties had been changed by copolymerization with methacrylic acid (MAA) or divinyl benzene. The second-stage polymers were copol

Signalling between plants and microorganisms

Popular Abstract in Swedish Växter kan bli attackerade av många olika sorters bakterier, svampar, virus, insekter och betande djur. Därför har växter utvecklat flera olika försvarssystem mot patogener. Bland annat kan de ha skyddande ytskikt, antimikrobiella molekyler och proteiner. Men växter kan också leva i symbios med bakterier och svampar. Baljväxter bildar rotknölar där kvävefixerade bakteriPlants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. In this work, different factors involved in plant-microbe interactions have been

What is systems science?

A most natural view is that systems science is a science dealing with systems and their systems properties. What, then, is science that it can deal with systems properties which by nature are deeply penetrating also into the systemic nature of our conceptual processes, of language, and of science itself. We start out from an independent view of the concept of science. Namely, that sciences are ded

Specific Precipitation of Biomolecules Using Synthetic Polymers

Purification is a very important stage in biotechnological processes. The traditionally used precipitation techniques are generally nonspecific and thus one or more chromatographic steps are normally required. There is thus a need for new approaches to improve existing techniques. New, more specific precipitation techniques have been introduced by the use of stimuli-responsive polymers. These poly

A 65-nm CMOS Area Optimized De-synchronization Flow for sub-V-T Designs

This paper proposes a process independent post layout de-synchronization flow implemented in tool command language working on designs operating in the sub-V-T regime. The overhead due to the self-timed operation is combated by introducing full-custom delay elements and latches for a standard 65-nm CMOS process. The flow offers the possibility to adjust granularity based on user requirements. Case

Weakly Fair Allocations and Strategy-Proofness

This paper investigates the problem of allocating two types of indivisible objects among a group of agents when a priority-order must be respected and only restricted monetary transfers are allowed. Since the existence of a fair (as in envy-free) allocation is not generally guaranteed, due to the restrictions on the money transfers, the concept of fairness is weakened, and a new concept of fairnes
