Hur utvecklas en växt? Om man studerar växter så upptäcker man ganska snart de många symmetrier och regelbundna former som finns i växtriket. Nya växtorgan såsom löv och blommor bildas ofta i regelbundna mönster, som exempelvis kan ge upphov till de spiraler som kan observeras på en ananas eller kotte. Beroende på frekvensen ochvinklarna mellan de nya organ som skapas, kan olika mönster hos växtenThe growth and development of plants exhibits a striking symmetry, visible in the regular arrangement of leaves and flowers. Plant development is carefully controlled at the molecular level by gene regulatory networks, and the symmetry of plants can be observed also in the molecular patterns of gene expression.This thesis investigates the molecular basis for spatial patterns of gene expression in

BACKGROUND: Gender differences regarding psychiatric ill-health are well known in the general population. However, not much research is done on people with intellectual disability, and especially not among older people with intellectual disability.METHODS: People with intellectual disability aged 55+ years in 2012 in Sweden were identified through a register containing information on those receivi

The aim of this paper is to describe, conceptualise and critically discuss how and with what consequences marketing is used to construct a mass market for vegan substitutes. Drawing on the concepts of the marketing device and qualification, it shows how Oatly – a Swedish company making oat-based products – enrols three sets of marketing devices, i.e. digital media, packaging and stores, to simulta

Purpose – The purpose of this paper is to explore the nature of brand contract in B2B from two perspectives: the theological and pragmatic.Design/methodology/approach – A review of the branding literature challenges the dominant notion of the brand covenant as a firm driven, unilateral promise, referred to as a theological contract. The study adds to this the pragmatic perspective of a social cont

The aim of this special section is to critically analyse the complex issues at workin understanding the theories, processes and practices of engagement as itrelates to media industries. There is a need to open up the notion of engagementas a concept that captures subjective and shifting relations with media. In sucha way, this section focuses on media engagement within the industry as multifaceted

Although more museums are opening now than at any time in the past, too little attention has been paid to the concrete ways in which cultural processes of commoditisation affect heritage production. How can collections speak to wider audiences as well as to local communities in ways that are economically sustainable? This is not a question that invites simple solutions. Turning to ethnographic fie

Lanatospora costata sp. n., a new microsporidian parasite of the adipose and connective tissue cells of Megacyclops viridis (Jurine, 1820) (Copepoda: Cyclopidae) is described. It was isolated from a woodland pool with a rich and diverse fauna of microsporidiainfected small crustaceans and insect larvae. The parasite is structurally similar to the genus Lanatospora Voronin, 1989, characterized by a

An experimental investigation of the tip flow characteristics between a gas turbine blade tip and the shroud was conducted by a pressure-test system and a particle image velocimetry (PIV) system. A three-times scaled profile of the GE-E3 blade with five film cooling holes was used as specimen. The effects on flow characteristics by the rim width and the groove depth of the squealer tip were reveal

A new scheme for NH2 detection by means of laser-induced fluorescence (LIF) with excitation around wavelength 385 nm, accessible using the second harmonic of a solid-state Alexandrite laser, is presented. Detection of NH2 was confirmed by identification of corresponding lines in fluorescence excitation spectra measured in premixed NH3-air flames and on NH2 radicals generated through NH3 photolysis

We address the question of which syntactic representation is best suited for FrameNet-based semantic analysis of English text. We compare analyzers based on dependencies and constituents, and a dependency syntax with a rich set of grammatical functions with one with a smaller set. Our study demonstrates that dependency-based and constituent-based analyzers give roughly equivalent performance, and

We sPRThow how to compute the permanent of an n×n integer matrix modulo pk in time nk+O(1) if p=2 and in time 2n/exp⁡{Ω(γ2n/plog⁡p)} if p is an odd prime with kp0 we can compute the permanent

In order to obtain better performance, gas turbines always operate with high inlet temperature. This contributes to a high level of thermal load on the first stage vane endwall. To ensure safe operation of a gas turbine within a proper temperature range, the cooling performance of the vane endwall must be further investigated. In the present study, effects of the mainstream turbulence and upstream
