With an example from climate

change research, problem-solving research could deal with how to optimise an emissions trading scheme, while critical research would question the very existence of market-based mechanisms such as trading schemes as solutions to climate change. While acknowledging that each school of thought has its strengths and weaknesses, Cox (1981) affirmed that there is no such thing as a theory in itself divorced from a standpoint in time and space; theory is always for someone and for some purpose. This epistemological claim functions as an organising principle in the matrix described in Fig. 2. The integrated research proceeds from different disciplinary perspectives and is grounded in both problem-solving and critical approaches, wherein epistemological reflexivity is a necessary prerequisite for successful interdisciplinary MK-0457 dialogue and integration to be discussed below. Towards sustainability science The critical analysis of natural scientific understanding, sustainability goals and sustainability pathways can serve as a basis for building theories and methods in sustainability science that can transcend the find more following crucial divides described. Nature and society

The lack of theories on nature–society interaction is a hurdle. Yet, a number of new approaches with different origins and with their own biases, strengths and weaknesses are emerging to bridge the gap between natural sciences and social sciences: industrial ecology (Ayres 1994; Fischer-Kowalski and Haberl 1997; Anderberg 1998), Thymidylate synthase ecological economics (Costanza 1997), transition theory (Rotmans et al. 2001), resilience theory (Folke et al. 2002), cultural theory (Verweij et al. 2006) and world systems analysis (Hornborg and Crumley 2006). Theories that capture the dynamic linkages between natural and social systems are, thus, in progress. Many integrative efforts in sustainability science rely on system thinking and modelling, scenario construction, envisioning exercises, and regional or spatial integration. Efforts to assess sustainability and translate science into

policy or planning processes at different levels are dominated by combinations of these approaches. The challenge is to move beyond these established approaches by focussing more on the dynamics of social, economic and political systems in relation to nature, ecology and the environment. Examples of this include research on Syk inhibitor coupled systems (Ostrom 2009) and coupled systems under pressure from globalisation (Young et al. 2006). Research into the integration of social and natural cycles could be a concrete task in this context (AIMES 2009). Science and society Theories and approaches that capture how scientific understanding of socio-ecological systems can contribute to global sustainability are also in progress, as exemplified by the Earth System Governance Project (Biermann et al.

In certain regions of Asia melioidosis is a major cause of human morbidity and acute systemic melioidosis has a case fatality rate of up to 50% even if treated [1, 2]. Melioidosis has been described in wild animals, but also in farm and pet animals and can be spread by animal trade and transport [3]. Both species are pathovars of a single genomospecies which was divided historically in two separate species due to their clinical impact and host tropism. CH5183284 cost B. thailandensis is the third closely related species of the so-called “Pseudomallei complex” which has been out-grouped from the species B. pseudomallei

based on arabinose fermentation and its markedly lower pathogenicity. B. thailandensis and B. pseudomallei are soil bacteria that share the same geographical distribution. B. mallei is a gram-negative, non-motile obligate pathogen and the causative agent of glanders and farcy in equines (horses, donkeys, mules). In horses, glanders primarily presents with purulent nasal discharge, inflammation of the mucous membranes of the upper respiratory tract, and poor general condition, whereas farcy is a chronic cutaneous disease with formation of nodules which may develop into ulcers. Equines are the only known reservoir. Contact with infected animals, ingestion of glanderous meat and exposure

to aerosols can cause B. mallei infections in Selleckchem Proteasome inhibitor humans. Human glanders is highly lethal ITF2357 purchase and resembles melioidosis. Chronic and latent infections can exacerbate into the acute form even after 15 years in both diseases. Both bacterial species are intrinsically resistant to many antibiotics including ampicillin and broad- and expanded-spectrum cephalosporines due to the production of a beta-lactamase [4]. B. mallei and B. pseudomallei have been classified by the CDC as priority

category B biological agents. Isolation and microbiological identification of B. pseudomallei and B. mallei from clinical samples can take up to one week. Commercial biochemical test systems for B. mallei are not available and B. pseudomallei may be misidentified as Chromobacterium violaceum much or other bacteria [5–7]. Latex agglutination using a monoclonal antibody was shown to be a valuable technique for the rapid identification of B. pseudomallei in positive blood cultures, but no commercial tests are available [8, 9]. Real-time PCR systems have been developed for diagnosing and differentiating as rapid alternatives to biochemical tests, but few have been validated on clinical samples [10–13]. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) for identification of bacteria has become a useful tool for the rapid identification of bacteria (see [14] for a recent review). In some studies intact cell mass spectrometry (ICMS) showed better correlation to genetic markers than conventional morphological classification [15].

The primer sequences were as follows: napA (forward, 5′-CCGGCTATCGTGGCAAGA-3′; reverse, 5′-CGGGAAGCTGTCGACATTG-3′); nirK

(forward, 5′-CCGCGCGACGCAAA-3′; reverse, 5′-TCGAGCGTATCGGCATAGG-3′); norC (forward, 5′-AGCTCACAGAGCAGGAACTGAAC-3′; reverse, 5′-TGATGCGGCTCGTCCATT-3′); and nosZ (forward, 5′-CGAGGATCTCACGCATGGAT-3′; reverse, 5′-GCGGTGCAACCTCCATGT-3′). sMC00128 was used as an internal standard [49, 50] (forward, 5′-ACGAGATCGAGATCGCCATT-3′; reverse, 5′-CGAACGAGGTCTTCAGCATGA-3′). Each PCR reaction contained 7.5 μl of SYBR Green PCR master mix (PE Applied Biosystems), 5 μl of cDNA and various final concentrations of each primer depending on the studied gene. This concentration was 0.2 μM for norC and sMC00128 and 0.4 μM for napA, nosZ and nirK. The final volume of the PCR reactions MK-8776 was 15 μl. The real-time PCR reactions were

performed on a 7300 Real Time PCR System (PE Applied Biosystems). The initial denaturing time of 10 min was followed by 40 PCR cycles consisting of 95°C for 15 s and 60°C for 60 s. A melting curve was run after MEK162 chemical structure the PCR cycles. During real-time PCR, the efficiency of nirK gene amplification was approximately equal to that of the housekeeping (internal standard) gene; in this case, the comparative CT method (also called ∆∆CT method) was applied for relative quantification. For the other genes, the amplification efficiencies were different from that of the housekeeping gene; the comparative CT method could not be applied, and it was necessary to use the standard curve method. The data were analysed ioxilan using the 7300 System Software (PE Applied Biosystems). The gene expression values under different conditions were expressed relative to the values of cells incubated under an initial O2 concentration of 2% in the absence of nitrate.

“Background Efficient light emission from Si-based structures and devices has drawn worldwide attention with the aim of developing an integrated optoelectronic platform on Si [1–6]. Such light emitters present an attractive application not only for inter-/intrachip optical interconnects but also, e.g., micro-displays and biological detection. Among the different

approaches, rare-earth ion-based materials are very promising candidates due to their outstanding optical properties. Recently, it has been demonstrated that erbium silicate has one order of magnitude higher optically active rare-earth ions than those CYTH4 done through doping, without clustering or precipitation [7–10]. This may open new and interesting perspectives for rare-earth applications in photonics. Among the various rare earths, Eu ions also have been attracting great interest in optoelectronic application because of its intense and stable emission in the visible region. Compared with other trivalent rare-earth ions, Eu2+ emission intensity is several orders stronger because of dipole-allowed transition. This makes for the successful application of Eu2+ in phosphors [11, 12], and electroluminescent devices, by incorporating Eu2+ (such as those doped in SiO2 and Eu silicate), have been demonstrated [13–15]. Bellocchi et al. have shown that the external quantum efficiency of Eu2SiO4 can be reached at about 10%, making Eu silicate of great interest for photonic application [16].
