The principles introduced by the Directive Concerning Integrated Pollution Prevention and Control (IPPC) (currently known as the Industrial Emissions Directive (2010/75/EU)) are innovative and have raised interests in the framework of the literature debate on environmental regulation. Many articles describe and analyze the application of the Directive in European countries, but only a few articles focus on how the interest for the Directive's principles, including the integrated approach, have reached countries outside the European Union. This paper aims to contribute to this topic, describing the experience of the authors in carrying out an EU-funded project on transferring the IPPC approach and Best Available Techniques (BAT) concepts to three Arab countries, i.e., Egypt, Morocco and Tunisia. The paper presents the experience referring to two sectors falling within the scope of the IPPC Directive: the textile and dairy sector. The objectives, methodologies, activities and experiences are described and can be used and valorized to integrate the IPPC approach and BAT concepts in the current environmental legislation of the three countries. © 2013 by the authors.

In this review, we provide a bird's eye view of recent developments in the field of pressure-sensitive adhesives (PSAs) derived from renewable monomeric building blocks. This emerging research field has been driven by increasing sustainability requirements in the adhesive industry and bridges the gap existing between highly optimized petroleum-based synthetic PSA systems, which display superior performance but lack biobased content, and historical PSAs derived from naturally occurring biopolymers (e.g., starch and natural rubber), which provide more environmentally friendly bonding solutions but have inherent technical limitations that prevent their more widespread implementation in today's technically demanding applications. We critically reviewed a representative (and exhaustive) survey of recent synthetic approaches to the development of biobased PSAs from the academic (articles) and industrial (patents) literature categorized in two families: chain-growth and step-growth polymerization routes. Finally, we draw a parallel between renewable synthetic PSAs and nature's self-adhesive glues, highlighting how the synergy between green chemistry and biomimetic concepts could inspire the emergence of a new generation of smart, synthetic, biobased PSAs with differentiated properties that approach the ones that are found in the natural world and with a wide spectrum of potential applications in the industrial and medical sectors. © 2014 Wiley Periodicals, Inc.

This study assessed an alternative concept for co-treatment of sewage and organic kitchen waste in Vietnam. The goal was to apply direct membrane filtration for sewage treatment to generate a permeate that is suitable for discharge. The obtained chemical oxygen demand (COD) concentrations in the permeate of ultrafiltration tests were indeed under the limit value (50 mg/L) of the local municipal discharge standards. The COD of the concentrate was 5.4 times higher than that of the initial feed. These concentrated organics were then co-digested with organic kitchen wastes at an organic loading rate of 2.0 kg VS/m(3).d. The volumetric biogas production of the digester was 1.94 0.34 m(3)/m(3).d. The recovered carbon, in terms of methane gas, accounted for 50% of the total carbon input of the integrated system. Consequently, an electrical production of 64 Wh/capita/d can be obtained when applying the proposed technology with the current wastes generated in Ho Chi Minh City. Thus, it is an approach with great potential in terms of energy recovery and waste treatment.

A method and system for providing pulsed power and data from a main control unit to slave units via a first bus. The main control unit has an AC signal generator for providing a plurality of first pulses (P1) on the bus for providing the power to the slave units. Each slave unit is AC-coupled to the bus via a first series capacitor arranged for converting the first pulses (P1) into second pulses (P2). Data communication from the main control unit to the slave units is established by modulating the first pulses (P1), and by demodulating the second pulses (P2). The modulation may be based on Pulse Position Modulation, Pulse Width Modulation, Pulse Count Modulation, Pulse Amplitude modulation. Zero, one or more bits may be communicated per first pulse. Optionally the slave units may communicate to the main control unit via a second bus.

The current invention concerns a method for identifying the elemental composition of and/or quantifying the presence of mono-isotopic elements in a molecule in a sample by computing a solution of a system of linear equations _()E_(i)n_()=F_(i), whereby the set of numbers F_(i )comprises said set of relative peak heights from the aggregated isotopic distribution and the coefficients E_(i) of said linear system comprise powers and/or power sums of roots r_(,i). The present invention also provides a method for analysing at least part of an isotopic distribution of a sample, comprising obtaining data comprising at least one probability q_(j )with which a jth aggregated isotopic variant of said molecule with mass number A_(j )occurs within said aggregated isotopic distribution; and computing a probability q_(i )with which an ith aggregated isotopic variant occurs within said aggregated isotopic distribution, by taking a linear combination of said at least one probability q_(j).

The present invention relates to a detection device and a method for detecting a presence of an object in a surveillance area. The device comprises at least one infrared radiation sensing element each adapted for generating a sensor signal related to a quantity of infrared radiation received from within the surveillance area by the infrared radiation sensing element, a processing unit and an output means for outputting a determined presence of the object and/or a property derived therefrom. The processing unit is adapted for: obtaining the at least one sensor signal; generating at least one contrast value by comparing the at least one sensor signal to at least one reference value; determining the presence of the object by evaluating a condition on said at least one contrast value; and adjusting the at least one reference value such that negative feedback is applied to the at least one contrast value.

A filter element includes an integrated permeate channel membrane (4) which has a flexible structure and includes an upper and lower membrane layer and a substrate material for supporting the membrane layers. The substrate is a 3D spacer fabric having an upper and a lower fabric surface, tied together and spaced apart by monofilament threads at a predefined distance. A frame system supports the membrane and sealing the integrated permeate channel at the edge of the membrane. The frame system includes a first frame profile and a second frame profile each of them having form and dimensions capable of surrounding the membrane. Each of the first and second frame profiles has inner parts and outer parts with the membrane (4) interposed between the first frame profile and the second frame profile. A filter module includes filter elements.

A method and corresponding device, for monitoring a charge of a battery. The method obtains a battery current measurement value and a battery voltage measurement value, and applies a current integration method to update a primary charge estimate value representative of the charge stored in the battery by taking into account the battery current measurement value. The method further determines an ancillary charge estimate value representative of the charge stored in the battery using a battery model taking into account the battery voltage measurement value, and determines an error value for the ancillary charge estimate value, in which the error value expresses the reliability of the battery model. The method also applies a correction to the primary charge estimate value as function of the ancillary charge estimate value and the error value. Interpretation of the correction applied in this manner allows determination of current sensor offset and battery capacity change.
