In vitro micro-propagation of endangered ornamental plant-Neotchihatchewia isatidea (Boiss.) Rauschert

The ornamental plant, Neotchihatchewia isatidea, is an endangered species of Turkey and threatened by complete extinction in the future. Therefore, in vitro multiplication of this species can be valuable forcommercial production and germplasm conservation. Immature embryos of N. isatidea were cultured for initiation on Murashige and Skoog medium (MS) supplemented with N6-benzylamino-purine (BAP)and -naphthaleneacetic acid (NAA). Shoot primordia were visible within 5 - 6 weeks and the shoot primordia later developed into normal shoots 10 - 12 weeks after the culture initiation on calli developedfrom immature embryos. Shoot tips were also excised from developed plantlets for direct shoot organogenesis and cultured on MS shoot induction medium supplemented with BAP (0.5, 1.0 and 2.0mg/l), kinetin (KIN) (0.5, 1.0 and 2.0 mg/l) and thidiazuron (TDZ) (0.05, 0.10 and 0.50 mg/l). Direct multiple shoots from shoot tips developed in most media tested. High shoot multiplication (3.73), high rooting(53 %) number of root per shoot (3.66) and survival ratio (46.6 %) were achieved

Background: A 28-year-old male smoker (6 pack-years) presented with complaints of dyspnea, cough and chest pain. Physical examination was unremarkable except for decreased respiratory sounds within anterior mid-lung zones bilaterally. Laboratory findings were within normal limits

The role of actor-networks in the early stage mobilisation of low carbon heat networks

Low carbon heat networks (LCHNs) offer great potential for carbon reduction and to reduce heat costs for consumers. In spite of these benefits, LCHNs provide for just two per cent of heat demand in the UK, when recent estimates suggest they have the potential to provide for around 43 per cent. It is within this context that the Pioneer Cities project (the project) was launched by the UK government, aiming to help local authorities overcome barriers to the deployment of LCHNs. This paper reports the findings of an evaluation of this project, drawing on 86 in-depth interviews with stakeholders across five local authority areas, analysed using elements of Actor Network Theory (ANT). The evaluation found that the project's success has been limited. Participating local authorities have encountered common challenges regarding marketisation; public sector retrenchment and a lack of experience in mobilising LCHNs. These factors militate against the formation of the robust actor-networks required to drive forward LCHNs. Analysis using ANT reveals insights into why LCHNs remain elusive in the UK and suggests that policy makers seeking to promote LCHNs need to do more to strengthen local authorities' ability to lead and deliver complex infrastructure projects

Factorization of absolutely continuous polynomials

In this paper we study the ideal of dominated (p,s)-continuous polynomials, that extend the nowadays well known ideal of p-dominated polynomials to the more general setting of the interpolated ideals of polynomials. We give the polynomial version of Pietsch s factorization Theorem for this new ideal. Our factorization theorem requires new techniques inspired in the theory of Banach lattices.The authors thank the referee for his/her suggestions. D.

Geographies of marketisation in English higher education: territorial and relational markets and the case of undergraduate student fees

In this paper, I use the case of the marketisation of higher education in England to contribute to the growing interest in placing markets, and processes of market making, more centrally within economic geographical research agendas. In particular, my argument focuses on the spatiality of marketisation through the specific case of the introduction of undergraduate student fees in England from 1998 onwards. I argue that the marketisation of English higher education has operated, implicitly at least, with a territorial logic in which students fees are justified through an assumption that the value of a degree from an English university will arise from graduate salary premiums in domestic graduate labour markets. However, I demonstrate how English higher education overflows this territorial framing through the internationalisation of student choice and graduate labour markets in ways that challenge the marketisation process itself. This analysis reveals the hitherto comparatively neglected role of extra- territorial relations in marketisation and the importance of these geographies for the future marketisation of higher education
