Effects of plant density and the number of emitters on plant growth and nitrate concentration in spinach cultivated in substrate

The effects of plant density and the number of emitters per Styrofoam box on plant growth and nitrate (NO3-) concentration were evaluated in spinach (Spinacia oleracea L. cv. Tapir). Spinach seedlings were transplanted at 45 days after emergence into Styrofoam boxes filled with the substrate and were grown during winter in an unheated greenhouse with no supplemental lighting. The experiment was carried out with four treatments, including two plant densities (160 and 280 plants/m2) and two number of emitters per Styrofoam box (4 and 8 emitters). Each planting box was irrigated daily and fertigated with a complete nutrient solution. Shoot dry weight was not affected by plant density. However, yield increased with plant density and emitter number. Leaf-blade NO3- concentration was not affected by the interaction between plant density and number of emitters, but petioles NO3- concentration was greater in treatment with 160 plants/m2 and 8 emitters. Although leaf-blade NO3- concentration was not affected by plant density, it decreased with the number of emitters. On the other hand, petiole NO3- concentration was not affected by plant density or number of emitters. Leaf-blade NO3- concentration ranged from 3.2 to 4.1 mg/g fresh weight, occurring the highest value in the treatment with 280 plants/m2 and 4 emitters. Petiole NO3- concentration ranged from 3.5 to 5.3 mg/g fresh weight, values that were higher than allowed by EU regulation.

Video-based training combined with flotation tank recovery does not improve three-point shooting in basketball

Video-based training combined with flotation tank recovery may provide an additional stimulus for improving shooting in basketball. A pre-post controlled trial was conducted to assess the effectiveness of a 3 wk intervention combining video-based training and flotation tank recovery on three-point shooting performance in elite female basketball players. Players were assigned to an experimental (n=10) and control group (n=9). A 3 wk intervention consisted of 2 x 30 min float sessions a week which included 10 min of video-based training footage, followed by a 3 wk retention phase. A total of 100 three-point shots were taken from 5 designated positions on the court at each week to assess three-point shooting performance. There was no clear difference in the mean change in the number of successful three-point shots between the groups (-3%; ±18%, mean; ±90% confidence limits). Video-based training combined with flotation recovery had little effect on three-point shooting performance.

The OHS regulatory challenges posed by agency workers: evidence from Australia

The purpose of this research is to analyse the problems for occupational health and safety (OHS)regulators posed by agency work/leased labour (also known as labour hire in Australasia), using Australian evidence. The analysis is based on an examination of prosecutions involving labour hire firms along with other documentary records (union, industry and government reports and guidance material). The study also draws on interviews with approximately 200 regulatory officials, employers and union representatives since 2001 and workplace visits with 40 OHS inspectors in 2004‐2005.The triangular relationship entailed in labour leasing, in combination with the temporary nature of most placements, poses serious problems for government agencies in terms of enforcing OHS standards notwithstanding a growing number of successful prosecutions for breaches of legislative duties by host and labour leasing firms. Research to investigate these issues in other countries and compare findings with those for Australia is required, along with assessing the effectiveness of new enforcement initiatives. The paper assesses existing regulatory responses and highlights the need for new regulatory strategies to combat the problems posed by labour. The OHS problems posed by agency work have received comparatively little attention. The paper provides insights into the specific problems posed for OHS regulators and how inspectorates are trying to address them.

How does complex adaptive system theory inform innovation in complex project based organisations?

Innovation enables organisations to endure by responding to emergence and to improve efficiency. Innovation in a complex organisation can be difficult due to complexities contributing to slow decision-making. Complex projects fail due to an inability to respond to emergence which consumes finances and impacts on resources and organisational success. Therefore, for complex organisations to improve on performance and resilience, it would be advantageous to understand how to improve the management of innovation and thus, the ability to respond to emergence. The benefits to managers are an increase in the number of successful projects and improved productivity. This study will explore innovation management in a complex project based organisation. The contribution to the academic literature will be an in-depth, qualitative exploration of innovation in a complex project based organisation using a comparative case study approach.

New frontiers and challenges for affordable housing provision in India

The global increase in the number of slums calls for policies which improve the conditions of the urban poor, sustainably.

The chapters provide ideas and tools for pro-poor interventions with respect to the provision of land for housing, building materials, labour, participation and finance. The book looks at the role of the various stakeholders involved in such interventions, including national and local governments, private sector organisations, NGOs and Community-based Organisations.

A gene-signature progression approach to identifying candidate small-molecule cancer therapeutics with connectivity mapping

Gene expression connectivity mapping has gained much popularity recently with a number of successful applications in biomedical research testifying its utility and promise. Previously methodological research in connectivity mapping mainly focused on two of the key components in the framework, namely, the reference gene expression profiles and the connectivity mapping algorithms. The other key component in this framework, the query gene signature, has been left to users to construct without much consensus on how this should be done, albeit it has been an issue most relevant to end users. As a key input to the connectivity mapping process, gene signature is crucially important in returning biologically meaningful and relevant results. This paper intends to formulate a standardized procedure for constructing high quality gene signatures from a user’s perspective.

Increase urban freight efficiency with delivery and servicing plan

Delivery and Servicing Plan (DSP) is an innovative logistics concept for more efficient organisation of deliveries from the point of view of the receiver of the goods. DSP actions tested in this study include reducing the number of suppliers, grouping deliveries, selecting less distant suppliers and others. It is shown that DSP can help reduce externalities and lead to a substantial reduction of costs. A new tool was developed to calculate the benefits of different DSP options for businesses and the public sector. Reductions in costs and externalities exceeding 50% have been demonstrated in a few cases. Remaining difficulties with the concept are organisational issues, lack of knowledge, need to give external advisory support for shop owners and the limited number of successful applications to date.

Actualización perfil de mercado de la Unión Europea

El Proyecto Actualización perfil de mercado unión europea, abarca el estudio de los perfiles de mercado de los 28 países (tras la adición de Croacia el 1 de julio del 2013) miembros de la unión europea (EU), que permita desarrollar una guía de análisis de mercado, por producto y por demanda; ayudando a empresarios colombianos e investigadores de mercados a mejorar la toma de decisiones dentro del intercambio comercial bilateral y crear un valor agregado y mayor desarrollo en la industria. Los empresarios colombianos, independientemente de su tamaño (grandes o PYMES) se pueden valer de la información recogida para evaluar su situación actual y la de los países miembros de la UE y formular estrategias de re-diseño o de incursión de mercado, haciendo posible identificar si sus decisiones son correctas y en caso contrario identificar soluciones y posibles cambios. A raíz del aumento de las relaciones comerciales entre Colombia y los diferentes bloques comerciales, es de vital importancia crear herramientas que aumenten las posibilidades de éxito a los empresarios nacionales y mejoren la relación entre ambas partes; en muchos casos los exportadores colombianos cuentan con bastante información acerca de los procesos necesarios para realizar una exportación e inclusive de cuales países son probablemente los más adecuados para llevar el producto; pero no tienen información detallada, por país, región, producto, y el comportamiento comercial de cada uno; objetivo final es eliminar esa incertidumbre y generar un mayor número de procesos de exportación exitosos y sostenibles.

Sothönans ( Fulica atra ) miljökrav vid häckning i utbredningsområdets randzon

In Sweden you will find the coot chiefly in the southern parts. The species winters in the southern part of the Baltic Sea and along the coasts of northern Europe. The number of coots is heavily decreased by harsh winters. The population of the coots in Sweden is estimated to 20 000 to 30 000 pairs. The region of Dalarna is the random zone for the breeding of coots in Sweden . During the summer of 2006 the coot was reported to reproduce in at least 31 lakes and rivers preferably in the southern part of the Dalarna region. From Lake Brunnsjön at least 50 pairs of coots were reported. Lake Brunnsjön is by far the most nutrient rich lake in Dalarna.From the three lakes that are included in the study, namely Lake Glistjärn, Lake Limsjön and Lake Kyrkbytjärn, the water analysis shows high pH values, well-buffered waters and meso- trophic waters.The number of successful breedings was eleven. Lake Glistjärn zero breeding, Lake Limsjön four and Lake Kyrkbytjärn seven breedings. The northernmost lake in Dalarna where breeding occurred is Lake Limsjön.

A New End-User Composition Model to Empower Knowledge Workers to Develop Rich Internet Applications

Enabling real end-user programming development is the next logical stage in the evolution of Internetwide service-based applications. Even so, the vision of end users programming their own web-based solutions has not yet materialized. This will continue to be so unless both industry and the research community rise to the ambitious challenge of devising an end-to-end compositional model for developing a new age of end-user web application development tools. This paper describes a new composition model designed to empower programming-illiterate end users to create and share their own off-the-shelf rich Internet applications in a fully visual fashion. This paper presents the main insights and outcomes of our research and development efforts as part of a number of successful European Union research projects. A framework implementing this model was developed as part of the European Seventh Framework Programme FAST Project and the Spanish EzWeb Project and allowed us to validate the rationale behind our approach.

Supporting End-User Development through a New Composition Model: An Empirical Study

End-user development (EUD) is much hyped, and its impact has outstripped even the most optimistic forecasts. Even so, the vision of end users programming their own solutions has not yet materialized. This will continue to be so unless we in both industry and the research community set ourselves the ambitious challenge of devising end to end an end-user application development model for developing a new age of EUD tools. We have embarked on this venture, and this paper presents the main insights and outcomes of our research and development efforts as part of a number of successful EU research projects. Our proposal not only aims to reshape software engineering to meet the needs of EUD but also to refashion its components as solution building blocks instead of programs and software developments. This way, end users will really be empowered to build solutions based on artefacts akin to their expertise and understanding of ideal solutions
