An improvement in photosynthetic rate promotes the growth of crop plants. The sink-regulation of photosynthesis is crucial in optimizing nitrogen fixation and integrating it with carbon balance. Studies on these processes are essential in understanding growth inhibition in plants with ammonium ((Formula presented.)) syndrome. Hence, we sought to investigate the effects of using nitrogen sources wi

The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mission is to repeatedly obtain high-precision astrometric and photometric measurements of one thousand million stars over the course of five years. The scientific value of the down-linked data, and the operation of the on

Background We attempt to develop a relatively comprehensive structural model of risk factors for drug abuse (DA) in Swedish men that illustrates developmental and mediational processes. Methods We examined 20 risk factors for DA in 48,369 men undergoing conscription examinations in 1969–70 followed until 2011 when 2.34% (n = 1134) of them had DA ascertained in medical, criminal and pharmacy regist

The effective mechanical properties of polymethyl-methacrylate (PMMA) reinforced with carbon nanotubes (CNTs) were evaluated by means of two approaches: experiments and a micromechanical model. With various concentrations of CNTs, two specimen fabrication processes were examined: hot pressing (HP) and injection molding (IM). Experiments included a series of uniaxial tensile tests guided by an ASTM

Nerve fibres play an important role in the regulation of gastric emptying. The aims of this study were to clarify the distribution, projections and origin of neuronal type nitric oxide synthase (NOS)-, tyrosine hydroxylase (TH)-, vesicular acetylcholine transporter (VAchT)- and peptide-containing nerve fibres of the rat pyloric sphincter. Extrinsic and local denervations of the sphincter were perf

Background: The aim of this study was to explore the feasibility of using a technique based on artificial neural networks for quality assurance of image reporting. The networks were used to identify potentially suboptimal or erroneous interpretations of myocardial perfusion scintigrams (MPS). Methods: Reversible perfusion defects (ischaemia) in each of five myocardial regions, as interpreted by on

Formulating and implementing a new strategy may be a challenging task, especially if it alters the way in which a company has operated and positioned itself before. This may be particularly true for companies within the forest industry, like manufacturers of paper packaging products, pursuing differentiated customer value and innovative solutions where, traditionally, success has been measured in

e concept of ecosystem services was originally developed to illustrate the benefits that natural ecosystems generate for society and to raise awareness for biodiversity and ecosystem conservation. In this article we identify major challenges and opportunities for ecologists involved in empirical or modeling ecosystem service research. The first challenge arises from the fact that the ecosystem ser

A new influenza virus that was first detected in people in April 2009, was initially referred to colloquially as "swine flu", since it contained genes from swine, avian and human influenza viruses. It can, however, not be transmitted by eating pork or dealing with pigs. In Egypt, several hundred thousand pigs were killed in May, in spite of advice from global health authorities that such an action

Three microperoxidases-hemin-6(7)-gly-gly-his methyl ester (HGGH), mesohemin-6(7)-gly-gly-his methyl ester (MGGH) and deuterohemin-6(7)-gly-gly-his methyl ester (DGGH)-have been prepared as models for heme-containing peroxidases by condensation Of glycyl-glycyl-L-histidine methyl ester with the propionic side chains of hemin, mesohemin and deuterohemin, respectively. The three microperoxidases dif

Popular Abstract in Swedish I september 1989 kom det till kanadensiska mi’kmaqindianers kännedom att ett enormt granitbrott (ett av de tre största i världen) planerades att öppnas vid Kellys Mountain på ön Cape Breton i östra Kanada. Mi’kmaqtraditionalister organiserade genast en fredlig trumceremoni på berget och en talesman deklarerade att det planerade granitbrottet var en förolämpning mot bådeThis dissertation seeks to explore historical changes in the lifeworld of the Mi’kmaq Indians of Eastern Canada. The Mi’kmaq culture hero Kluskap here serves as a key persona in discussing issues such as traditions, changing conceptions of land, and human-environmental relations. In order not to depict Mi’kmaq culture as timeless, two important periods in its history are examined. The first study

Introduction. Rho kinases (ROKs) cause calcium-independent modulation of smooth muscle contraction. A significant role for the RhoA/ROK pathway in mediating the contraction of the penile erectile tissue has been suggested. Moreover, it has been postulated that ROK activity might represent a key factor in the pathophysiology of erectile dysfunction. Up until today, little is known on the significan

Abstract Purpose: To describe the most prominent use of or perceived unmet need of assistive technology (AT) and to compare the characteristics of users, non-users and those expressing perceived unmet need with respect to overall health, independence in everyday life, environmental barriers and socio-demographic features. Method: The study is based on data collected in the "Home and Health in the

In an era of lifelong learning, empowerment of the learner becomes fundamental. Therefore ex-ploitation of the full potential of learning objects depends upon creation of an appropriate infra-structure to promote symmetrical control of inquiry. The learner needs to be empowered because learning is a discovery process and thus must be under his or her own control. In early stages of education it

In the construction industry, sustainability and greening is more than just a passing trend. It has become an important agenda since the building sector has immense environmental impacts. It accounts for 42% of final energy consumption and about 35% of all greenhouse gas emissions. In order to meet these challenges, the construction industry needs to change and adopt new working procedures which t

In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. Nevertheless, high production costs associated with traditional PHA production based on fermentation by pure microbial cultures have so f

Fields of Green and Gold är en multipel fallstudie som analyserar placeringen och etableringen av två storskaliga, berömda och påkostade golfanläggningar för att därigenom undersöka den exklusiva golfens politiska ekologi. De fall som studeras är Bro Hof Slott Golf Club i Upplands-Bro - som öppnade 2007 - och Trump International Golf Links Scotland i Aberdeenshire - som öppnade 2012. Att analyseraFields of Green and Gold is a multiple case study analysing the placing and establishment of two large-scale, high-profile, upmarket golf developments with the aim of exploring a political ecology of high-end golf. The cases studied are Bro Hof Slott Golf Club in Upplands-Bro, opened in 2007, and Trump International Golf Links Scotland in Aberdeenshire, opened in 2012. Reading these two cases toge

Autoignition of a homogeneous mixture is very sensitive to operating conditions, therefore fast control is necessary for reliable operation. There exists several means to control the combustion phasing of an Homogeneous Charge Compression Ignition (HCCI) engine, but most of the presented controlled HCCI result has been performed with single-input single-output controllers. In order to fully operat

The process of transforming the industrial economy into a society largely based on the production and dissemination of information and knowledge has widespread implications for cities and regions as well as organisations and individuals. And while the economy is increasingly global, the differences in economic development between cities and regions will not necessarily disappear. Indeed, the diver

More and more researchers are considering the omnibus eye movement sequence—the scanpath—in their studies of visual and cognitive processing (e.g. Hayes, Petrov, & Sederberg, 2011; Madsen, Larson, Loschky, & Rebello, 2012; Ni et al., 2011; von der Malsburg & Vasishth, 2011). However, it remains unclear how recent methods for comparing scanpaths perform in experiments producing variable
