Flanders (Belgium) is one of the most densely populated regions in Europe. Intensive land use, widespread suburbanization, inadequate environmental qualities, and fragmentation everywhere deteriorate living conditions and put pressure on species and natural habitats. In the past, several governmental initiatives were launched to establish a coherent ecological network to improve the situation. Despite the set objectives, only a little progress was made. Therefore, to establish green infrastructure, a new approach that moves away from previous top-down and one-sided strategies is developed. Making use of Green Infrastructure as a boundary concept, interpretation was given through an open and participatory process. The core is the identification of common objectives (ecosystem services or other objectives/services), the selection of appropriate green infrastructure elements to support the services, and the co-design of a network taking the local socio-ecological realm into account. By applying the methodology in concrete urban and rural projects, we learned that establishing strong coalitions of stakeholders, obtaining and sharing reliable knowledge of the systems are key to an effective realization of green infrastructure.

Background: Conventional periodontal treatment, performed quadrant by quadrant in multiple visits, was re-evaluated in the early 1990s when the full-mouth disinfection concept was introduced. Over the years, several modifications to the full-mouth disinfection approach have been suggested. Objective: The purpose of this article is to review the evolution of full-mouth disinfection during the past 20 years, to specify its indications and to consider the prospects for this approach. Materials and Methods: An electronic and manual search of the literature, ending in December 2016, was performed by two independent researchers. Only pivotal studies and randomized controlled clinical trials published in the English language that evaluated a new approach to full-mouth disinfection were selected. Results: According to the studies included in our analysis (21 articles), several modified full-mouth disinfection protocols have been designed including: full-mouth treatment without chlorhexidine, the extension of hygiene methods and an increase in the duration of post-treatment chlorhexidine use, the replacement of chlorhexidine with other antiseptics, supplementation with antibiotics or probiotics, full-mouth antimicrobial photodynamic therapy and one-stage full-mouth disinfection combined with a periodontal dressing. Conclusion: Since 1995, several modifications have been suggested to improve the effectiveness of full-mouth disinfection. The majority of the studies demonstrate that the results obtained with full-mouth disinfection and its variants are equivalent to each other and to those obtained with the conventional quadrant method. Currently, the selection of this technique remains empirical and depends on the preferences of the practitioner and the patient. In the future, a patient-centered approach should be the best indication for the use of this technique.

Copper Tolerant

The corrosion of copper and copper alloys in a marine environment is of great concern because of their widespread use in heat exchangers and steam condensers in which natural seawater is the coolant. It has become increasingly evident that microorganisms play an important role in the corrosion of a number of metals and alloys under a variety of environments. For the past 15 years the use of SEM has proven to be useful in studying biofilms and spatial relationships between bacteria and localized corrosion of metals. Little information, however, has been obtained using TEM capitalizing on its higher spacial resolution and the transmission observation of interfaces. The research presented herein is the first step of this new approach in studying the corrosion with biological influence in pure copper.Commercially produced copper (Cu, 99%) foils of approximately 120 μm thick exposed to a copper-tolerant marine bacterium, Oceanospirillum, and an abiotic culture medium were subsampled (1 cm × 1 cm) for this study along with unexposed control samples.

In the past few decades, there has been lot of focus on the issue of sustainability. This has occurred due to the growing concerns related to climate change and the growing awareness about environmental concerns. Also, the competition at global level has led to the search for the most sustainable route in the industries. The current research work deals with the selection of green supplier in a Nickle coating industry based on certain weighted green attributes. For this purpose, a hybrid tool comprising of Fuzzy AHP (Fuzzy Analytical Hierarchy) and VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) is used. The Fuzzy AHP is used for assigning proper weights to the selected criteria for supplier evaluation, while VIKOR is used for final supplier selection based on the weighted criteria. The three criterions for green supplier selection are, Ecological packaging, Corporate socio-environmental responsibility and Staff Training. The outcome of the integrated model may serve as a steppingstone to other SMEs in different sectors for selecting the most suitable supplier for addressing the sustainability issue.

Over the past decade, on-surface fabrication of organic nanostructures has been widely investigated for the development of molecular electronic devices, nanomachines, and new materials. Here, we introduce a new strategy to obtain alkyl oligomers in a controlled manner using on-surface radical oligomerisations that are triggered by the electrons/holes between the sample surface and the tip of a scanning tunnelling microscope. The resulting radical-mediated mechanism is substantiated by a detailed theoretical study. This electron transfer event only occurs when <i>V</i><sub>s</sub> < -3 V or <i>V</i><sub>s</sub> > + 3 V and allows access to reactive radical species under exceptionally mild conditions. This transfer can effectively ‘switch on’ a sequence leading to formation of oligomers of defined size distribution due to the on-surface confinement of reactive species. Our approach enables new ways to initiate and control radical oligomerisations with tunnelling electrons, leading to molecularly precise nanofabrication.

Potential Therapeutics

Triterpenoids are natural compounds with a large variety of biological activities such as anticancer, antiviral, antibacterial, antifungal, antiparazitic, antiinflammatory and others. Despite their low toxicity and simple availability from the natural resources, their clinical use is still severely limited by their higher IC50 and worse pharmacological properties than in the currently used therapeutics. This fact encouraged a number of researchers to develop new terpenic derivatives more suitable for the potential clinical use. This review summarizes a new approach to improve both, the activity and ADME-Tox properties by connecting active terpenes to another modifying molecules using click reactions. Within the past few years, this synthetic approach was well explored yielding a lot of great improvements of the parent compounds along with some less successful attempts. A large quantity of the new compounds presented here are superior in both activity and ADME-Tox properties to their parents. This review should serve the researchers who need to promote their hit triterpenic structures towards their clinical use and it is intended as a guide for the chemical synthesis of better drug candidates.

Evidence-based assessment relies on research and theory to inform the selection of constructs to be assessed for a specific assessment purpose, the methods and measures to be used in the assessment, and the manner in which the assessment process unfolds. An evidence-based approach to clinical assessment necessitates the recognition that, even when evidence-based instruments are used, the assessment process is a decision-making task in which hypotheses must be iteratively formulated and tested. In this chapter, we review (a) the progress that has been made in developing an evidence-based approach to clinical assessment in the past decade and (b) the many challenges that lie ahead if clinical assessment is to be truly evidence-based.

AbstractUsing brain atlases to localize regions of interest is a requirement for making neuroscientifically valid statistical inferences. These atlases, represented in volumetric or surface coordinate spaces, can describe brain topology from a variety of perspectives. Although many human brain atlases have circulated the field over the past fifty years, limited effort has been devoted to their standardization. Standardization can facilitate consistency and transparency with respect to orientation, resolution, labeling scheme, file storage format, and coordinate space designation. Our group has worked to consolidate an extensive selection of popular human brain atlases into a single, curated, open-source library, where they are stored following a standardized protocol with accompanying metadata, which can serve as the basis for future atlases. The repository containing the atlases, the specification, as well as relevant transformation functions is available in the neuroparc OSF registered repository or https://github.com/neurodata/neuroparc.
