Recycling industrial co2 into cost-competitive protein for high-value, sustainable animal feed

Animal feed producers are looking for alternative proteins because protein from conventional sources such as soy production and fishmeal face big sustainability issues, reflected in overfishing and deforestation. Deep Branch has developed a sustainable, highly scalable gas fermentation technology, that takes large volumes of CO2 from industrial emissions and transforms them into Proton™, a Single Cell Protein (SCP) optimised for animal nutrition. Proton™ has the potential for significant and, in the long-term, complete replacement of soy and fishmeal. Proton™ can be tailored to meet the precise requirements of animal feed companies and produced at scale in a sustainable and cost-competitive manner. Deep Branch has successfully tested the technology in a containerised, mobile unit at an industrial site and demonstrated nutritional viability. The company's initial focus will be on the €44bn aquaculture feed markets, with the €100bn+ monogastric market to follow. Within five years, Deep Branch aims to have full commercial-scale technology co-located with a CO2 emitting industrial partner, producing >50,000 tonnes of SCP per year. Feed producers have expressed their interest in purchasing this product once available in commercial volume; the company has already started co-developing feed recipes based on Proton™ and has LOIs and trial partner agreements from two major feed producers. At the other end of the value chain, the technology will offer large carbon emitters a new way to valorise their CO2. Once off-take has been secured and the production process and product quality validated, Deep Branch will build the first full-scale production facility, legally structured in a joint venture with a carbon-intensive industrial company. The objectives of the project are to build a Pilot Plant capable of producing >200 kg Proton™ per month, to fully validate the nutritional viability of Proton™, to complete the design for a demo plant and to secure necessary IP protection.
Quantitative real-time PCR (qPCR) detection chemistries affect enumeration of the Dehalococcoides 16S rRNA gene in groundwater

Quantitative real-time PCR (qPCR) commonly uses the fluorogenic 5' nuclease (TaqMan) and SYBR Green I (SG) detection chemistries to enumerate biomarker genes. Dehalococcoides (Dhc) are keystone bacteria for the detoxification of chlorinated ethenes, and the Dhc 16S ribosomal RNA (rRNA) gene serves as a biomarker for monitoring reductive dechlorination in contaminated aquifers. qPCR enumeration of Dhc biomarker genes using the TaqMan or SG approach with the same primer set yielded linear calibration curves over a seven orders of magnitude range with similar amplification efficiencies. The TaqMan assay discriminates specific from nonspecific amplification observed at low template concentrations with the SG assay, and had a 10-fold lower limit of detection of ~3 copies per assay. When applied to Dhc pure cultures and Dhc-containing consortia, both detection methods enumerated Dhc biomarker genes with differences not exceeding 3-fold. Greater variability was observed with groundwater samples, and the SG chemistry produced false-positive results or yielded up to 6-fold higher biomarker gene abundances compared to the TaqMan method. In most cases, the apparent error associated with SG detection resulted from quantification of nonspecific amplification products and was more pronounced with groundwater samples that had low biomarker concentrations or contained PCR inhibitors. Correction of the apparent error using post-amplification melting curve analysis produced 2 to 21-fold lower abundance estimates; however, gel electrophoretic analysis of amplicons demonstrated that melting curve analysis was insufficient to recognize all nonspecific amplification. Upon exclusion of nonspecific amplification products identified by combined melting curve and electrophoretic amplicon analyses, the SG method produced false-negative results compared to the TaqMan method. To achieve sensitive and accurate quantification of Dhc biomarker genes in environmental samples (e.g., groundwater) and avoid erroneous conclusions, the analysis should rely on TaqMan detection chemistry, unless additional analyses validate the results obtained with the SG approach.
OPTICAL DISCRIMINATORS AND SYSTEMS AND METHODS

An optical multi-filter discriminator suitable for treating optical signals from an optical signal source, e.g., a direct modulated laser ("DML"), comprises a first optical filter, a second optical filter optically coupled to the first optical filter, an input port operative to receive optical signals from an optical signal source and oriented to launch the optical signals directly or indirectly to the first optical filter, and an output port oriented to receive optical signals treated by the multiple optical filters and operative to pass the optical signals directly or indirectly to an optical waveguide "downstream" of the discriminator. The first filter is transmissive (i.e., at the angle of incidence received from the input port) of at least a first wavelength band having a first center wavelength and reflective (again, meaning in this instance at the angle of incidence received from the input port) of at least a second wavelength band different from the first wavelength band. The optical multi-filter discriminator defines an optical path for optical signals in the first wavelength band received by the input port. The optical path includes at least (i) transmission from the input port directly or indirectly to and through the first optical filter, and (ii) then, prior to the output port, from the first optical filter directly or indirectly to the second optical filter at an angle of incidence at which the second optical filter is reflective of the first wavelength band. The at least two filters of the optical multi-filter discriminator can be packaged together in a common housing along with some or all of the other components, if any, of the optical multi- filter discriminator, e.g., lenses, isolators, mounting components, etc. An optical communication system comprises a DML or other optical signal source optically coupled to one or more of the aforesaid optical multi-filter discriminators. A method of operating an optical communication system comprises actuating an optical signal source to generate optical signals to one or more of the aforesaid optical multi-filter discriminators to increase the extinction ratio, and by passing the signals through the multi-discriminator to a downstream optical fiber or other optical waveguide.
The effectiveness of consultation-liaison psychiatry in the general hospital setting: A systematic review

The aim of this study was to review how the effectiveness of consultation liaison psychiatry (CLP) services has been measured and to evaluate the strength of the evidence for effectiveness.Systematic review of medical databases using broad search terms as well as expert opinion was sought. The literature search was restricted to studies of general, whole-of-hospital inpatient CLP services.Forty articles were found and grouped into five measurements of effectiveness: cost effectiveness including length of stay, concordance, staff and patient feedback, and follow-up outcome studies. All measurements contributed to the evaluation of CLP services, but no one measure in isolation could adequately cover the multifaceted roles of CLP. Concordance was the only measurement with an established, consistent approach for evaluation. Cost effectiveness and follow-up outcome studies were the only measures with levels of evidence above four, however the three follow-up outcome studies reported conflicting results. Subjective evidence derived from patient and staff feedback is important but presently lacking due to methodological problems. The effectiveness of CLP services was demonstrated by cost-effectiveness, earlier referrals to CLP predicting shorter length of stay, and concordance with some management recommendations.There is evidence that some CLP services are cost-effective and reduce length of stay when involved early and that referrers follow certain recommendations. However, many studies had disparate results and were methodologically flawed. Future research should focus on standardising patient and staff feedback, and short-term patient outcomes.
Seasonal variations of transport pathways and potential sources of PM2.5 in Chengdu, China (2012–2013)

Seasonal pattern of transport pathways and potential sources of PM2.5 in Chengdu during 2012–2013 were investigated based on hourly PM2.5 data, backward trajectories, clustering analysis, potential source contribution function (PSCF), and concentration-weighted trajectory (CWT) method. The annual hourly mean PM2.5 concentration in Chengdu was 97.4 mg·m–3. 5, 5, 5 and 3 mean clusters were generated in four seasons, respectively. Short-distance air masses, which travelled within the Sichuan Basin with no specific source direction and relatively high PM2.5 loadings (>80 mg·m–3) appeared as important pathways in all seasons. These short pathways indicated that emissions from both local and surrounding regions of Chengdu contributed significantly to PM2.5 pollution. The cities in southern Chengdu were major potential sources with PSCF>0.6 and CWT>90 mg·m–3. The northeastern pathway prevailed throughout the year with higher frequency in autumn and winter and lower frequency in spring and summer. In spring, long-range transport from southern Xinjiang was a representative dust invasion path to Chengdu, and the CWT values along the path were 30-60 mg·m–3. Long-range transport was also observed in autumn from southeastern Xinjiang along a northwesterly pathway, and in winter from the Tibetan Plateau along a westerly pathway. In summer, the potential source regions of Chengdu were smaller than those in other seasons, and no long-range transport pathway was observed. Results of PSCF and CWT indicated that regions in Qinghai and Tibet contributed to PM2.5 pollution in Chengdu as well, and their CWT values increased to above 30 mg·m–3 in winter.
Robustness, Specificity, and Reliability of an In-Ear Pulse Oximetric Sensor in Surgical Patients

For many years, pulse oximetry has been widely used in the clinical environment for a reliable monitoring of oxygen saturation ( SpO2) and heart rate. But since common sensors are mainly placed to peripheral body parts as finger or earlobe, it is still highly susceptible to reduced peripheral perfusion, e.g., due to centralization. Therefore, a novel in-ear pulse oximetric sensor (placed against the tragus) was presented in a prior work which is deemed to be independent from perfusion fluctuations due to its proximity to the trunk. Having demonstrated the feasibility of in-ear SpO2 measurement with reliable specificity in a laboratory setting, we now report results from a study on in-ear SpO2 in a clinical setting. For this, trials were performed on 29 adult patients undergoing surgery. In-ear SpO2 data are compared with SaO2 data obtained by blood gas analysis, and with three reference pulse oximeters applied to the finger, ear lobe, and forehead. In addition, we derived an SpO2-independent perfusion index by means of the wavelengths used. The feasibility and robustness of in-ear SpO2 measurement is demonstrated under challenging clinical conditions. SpO2 shows good accordance with SaO2, a high level of comparability with the reference pulse oximeters, and was significantly improved by introducing a new algorithm for artifact reduction. The perfusion index also shows a good correlation with the reference data.
The use of chicken feather fibers as filling material in Winter clothes for heat insulation purposes

Purpose The purpose of this paper is to investigate if the fibers obtained from chicken feathers have a possibility to be used or not used in Winter outerwears as a filling material in terms of thermal insulation parameters. Design/methodology/approach In the study, thermal properties of the heat-resistant interlining samples produced from the chicken feathers fibers were analyzed in comparison with the samples produced from the industrial filling materials. Findings In the study, it was revealed that the use of chicken feathers fibers as filling material in Winter outerwears was possible. Practical implications The use of chicken feather fibers in Winter outerwears as a filling material will be an extremely low-cost alternative to pile flies of water birds which are sufficiently expensive filling materials. Social implications A significant portion of the chicken feather, which is released as a by-product in the production of chicken meat, is destroyed as industrial waste by digging or burning. Some of this product is used in the production of such cheap products as poultry feed. In the case of the production of fibers from the chicken feather, the use of these fibers as a filler in Winter clothing along with environmental protection will allow the use of this product for the production of products of higher cost. Originality/value The use of feathers’ material as a filling material in Winter outerwears has been known since ancient times. Due to the rough structure and low elasticity of chicken feathers, chicken feathers are not the best raw material for this purpose. This study revealed that it is possible to use chicken feathers as a filling material in terms of heat protection. The study is original in this respect.
Microarray Analysis of the Ler Regulon in Enteropathogenic and Enterohaemorrhagic Escherichia coli Strains

The type III protein secretion system is an important pathogenicity factor of enteropathogenic and enterohaemorrhagic Escherichia coli pathotypes. The genes encoding this apparatus are located on a pathogenicity island (the locus of enterocyte effacement) and are transcriptionally activated by the master regulator Ler. In each pathotype Ler is also known to regulate genes located elsewhere on the chromosome, but the full extent of the Ler regulon is unclear, especially for enteropathogenic E. coli. The Ler regulon was defined for two strains of E. coli: E2348/69 (enteropathogenic) and EDL933 (enterohaemorrhagic) in mid and late log phases of growth by DNA microarray analysis of the transcriptomes of wild-type and ler mutant versions of each strain. In both strains the Ler regulon is focused on the locus of enterocyte effacement - all major transcriptional units of which are activated by Ler, with the sole exception of the LEE1 operon during mid-log phase growth in E2348/69. However, the Ler regulon does extend more widely and also includes unlinked pathogenicity genes: in E2348/69 more than 50 genes outside of this locus were regulated, including a number of known or potential pathogenicity determinants; in EDL933 only 4 extra-LEE genes, again including known pathogenicity factors, were activated. In E2348/69, where the Ler regulon is clearly growth phase dependent, a number of genes including the plasmid-encoded regulator operon perABC, were found to be negatively regulated by Ler. Negative regulation by Ler of PerC, itself a positive regulator of the ler promoter, suggests a negative feedback loop involving these proteins.
Untangling the impacts of technological transformations, globalisation and demographic change to foster shared prosperity in europe

Technological transformations, globalisation and demographic changes are the three key mega-trends posing socio-economic challenges and opportunities for the EU. UNTANGLED aims to fill knowledge gaps about these trends by pursuing three main goals: (1) to provide detailed analyses at the macro-, regional-, sectoral-, and micro-level concerning the effects of these trends on labour market outcomes and inequality, and their winners and losers; (2) to develop comprehensive, model-based scenarios of the impacts of these trends in the next decades, overall and for various subpopulations, sectors and regions; (3) to develop policy recommendations fostering shared prosperity. UNTANGLED contributes to the work programme’s goal of promoting inclusive and evidence-based policy and informed public debates. In measuring effects, we disentangle the joint impacts of the trends on the changing demand of skills, employability, wage and income inequality, and mobility and migration patterns. We pay attention to effects by gender, age, skill level, and firm type. We use an interdisciplinary approach that combines quantitative and qualitative methods and adopts a cross-country perspective, covering the entire EU and accounting for developments in other continents. This helps to project the impact of shocks on global value chains. Our scenarios are firmly based on analytical results and created with two complementary models to provide robust results at the country-, sector- and regional-level. To develop assumptions and ensure relevance of scenarios, we engage in extensive consultations and set up feedback loops with stakeholders, which complement and validate the economic and institutional analyses. These stakeholder consultations help to develop concrete policy proposals aimed at shared prosperity. We deliver research papers and policy briefs. To maximise UNTANGLED’s impact, we disseminate the lessons learned and policy proposals to policy-makers, stakeholders and the public.
Parallel photogrammetry system for object panoramas

The preservation of cultural heritage by using digitization techniques is a very common method used by many European countries nowadays. The digital 3D modeling offers users the most realistic and trustworthy way of preserving precious artifacts from the various areas such as: history, art, biology, etc. The digital 3D models have wide application in science, education and industry. The most accurate method of creating realistic 3D models is panorama photography, which offers users a precise way of capturing reality. The only method of creating the digital 3D model from panorama photography is photogrammetry, however currently available methods of processing and computing might be considered as very time consuming and not reliable.
Parallel photogrammetry system (PAPHOS) serves the need for processing high-resolution object panoramas into digital 3D models. The whole system continuously processes object panoramas from EDICO´s digitization system WITIKON with high resolution and special boundary conditions. This novel approach rapidly increases visual quality and decreases the time of 3D model computation due to using parallel photogrammetry algorithms.
Whole computing is performed in the cloud or local CPU/GPU cluster. Project reacts to customer needs, such as less time consuming operations in the computing process and possibility of photogrammetry parameters change, better control of final 3D model, and possibility of using cloud computing. Problems outlined and solutions proposed are based on our previous research projects in the field of cultural heritage digitization.
With PAPHOS system EDICO SK plans to grow up in the terms of its team (+ 15 employees by 2021) and sales (+ 3,6 M € of revenue in 2021) by targeting markets in the field of cultural heritage on EU-scale and later also worldwide. After minor modifications the PAPHOS system can be used also for other market segments like videogame development or movie industry.
FLUID HEATER AND ASSOCIATED METHODS

Described examples relate to a downhole fluid heater, comprising a fluid heating assembly (12) comprising a heating chamber (18) for receiving a fluid. The fluid heating assembly (12) is configured to agitate a heat transfer fluid in the heating chamber (18) so as to impart thermal energy and heat the heat transfer fluid.
MOBILE RADIO SERVICE OVER CATV NETWORK

Passive elements in a CATV network (141) pass mobile radio network (102) signals without modification. The CATV network (141) carries both television and data as before, but also cellular or PCS signals (101). A cellular entrance module CEEM (110) provides an interface between the mobile radio terminal and the CATV network (141). Because the CATV network (141) is modified to transport the mobile radio signals, the mobile radio signals can be passed without modification to format or frequency.
Radial to axillary nerve neurotization for brachial plexus injury in children: a combined case series

Object Axillary nerve palsy, isolated or as part of a more complex brachial plexus injury, can have profound effects on upper-extremity function. Radial to axillary nerve neurotization is a useful technique for regaining shoulder abduction with little compromise of other neurological function. A combined experience of this procedure used in children is reviewed. Methods A retrospective review of the authors' experience across 3 tertiary care centers with brachial plexus and peripheral nerve injury in children (younger than 18 years) revealed 7 cases involving patients with axillary nerve injury as part of an overall brachial plexus injury with persistent shoulder abduction deficits. Two surgical approaches to the region were used. Results Four infants (ages 0.6, 0.8, 0.8, and 0.6 years) and 3 older children (ages 8, 15, and 17 years) underwent surgical intervention. No patient had significant shoulder abduction past 15° preoperatively. In 3 cases, additional neurotization was performed in conjunction with the procedure of interest. Two surgical approaches were used: posterior and transaxillary. All patients displayed improvement in shoulder abduction. All were able to activate their deltoid muscle to raise their arm against gravity and 4 of 7 were able to abduct against resistance. The median duration of follow-up was 15 months (range 8 months to 5.9 years). Conclusions Radial to axillary nerve neurotization improved shoulder abduction in this series of patients treated at 3 institutions. While rarely used in children, this neurotization procedure is an excellent option to restore deltoid function in children with brachial plexus injury due to birth or accidental trauma.
Creating a global network of shared service centres for accounting

Purpose The purpose of this paper is to contribute to the understanding of the practice of IT‐enabled management control change, in particular how IT‐driven change is made possible from a practical perspective in a global context. It does so by investigating the redesign of the telecommunications company Ericsson's global finance and accounting function from an independent structure of numerous national chief financial officer units into one interdependent global network of shared service centres. Design/methodology/approach Ericsson's transformation was followed by drawing mainly on interviews and documents. The data were analysed using narrative and temporal bracketing strategies for theorising from process data. Findings The paper illustrates how IT‐enabled management control change unfolds as a continuous interaction between a dynamic organisational structure (social dimension) and a less, but still, dynamic IT (material dimension) across time. The study also highlights how such a process is metaphorically similar to the form of a hermeneutic spiral rather than the common perspective of an arrow from the present to the future. Research limitations/implications The focus of the paper is on positive organisational change and how transformation is possible from a strategic and managerial point of view. Hence, less focus is placed on the employee perspective. Practical implications This paper stresses the importance of pre‐understanding, an openness to trials and learning, and a dynami stance towards the moving targets of IT and organisation. Originality/value The paper provides rich empirical material. The analysis includes contemporary issues, and the practice of IT‐enabled management control change.
