Techno-economic Assessment of Carbon Utilisation Potential in Europe

The purpose of this work is to analyse different carbon capture and utilisation (CCU) options, and hence to identify the role of CCU on the future European energy and industrial sectors. This work carries out the techno-economic analyses of methanol synthesis and accelerated aqueous carbonation of waste (fly ash) as two differentiated options for CO2 conversion. Process flow modelling is used to evaluate the operational and cost performances of two conceptual designs. Calibration and validation of the models are completed to then assess diverse operational, economic and environmental key performance indicators (KPIs). The inlet CO2 and fly ash originate from a conventional power plant. The needed hydrogen for the methanol case is produced by water electrolysis. The work puts into relevance the differences in performance and costs for the two processes analysed. Future work will contemplate other CCU processes and a global market study in the European context that focuses on (i) current prices and demands for the products, and (ii) the analysis of their foreseen market evolution and price elasticity.JRC.F.6-Energy Technology Policy Outloo

Carbon Capture and Utilisation Workshop: Background and proceedings

The utilisation of CO2 as technological fluid or as feedstock in chemical processes and in biotechnological applications has the potential to be a very efficient tool when merged with development of innovative and feasible technologies that have less-intensive energy and materials consumption and the capacity of temporary or permanent storage of CO2 (other than geological storage). The Joint Research Centre of the European Commission, Institute for Energy and Transport, and the Directorate General for Climate Action co-hosted a workshop on CO2 re-use technologies in Brussels on the 7th June 2013. The aim of the workshop was to present how the most promising pathways for CO2 re-use are related to climate and energy technology policies, facilitate a dialogue between stakeholders (industry, academia and policy makers) and address the challenges for a possible large scale roll-out of CO2 re-use technologies. A number of six presentations from experts focused on the state-of-the art of the technology, the needs of the sector for large scale deployment and the impact of the CO2 re-use products on the market. In particular, the workshop focused on three promising pathways, i.e. methanol production, mineralisation and polymer production.JRC.F.6-Energy systems evaluatio

Fragmentation Properties of Three-membered Ring Heterocyclic Molecules by Partial Ion Yield Spectroscopy: C2H4O and C2H4S

We investigated the photofragmentation properties of two three-membered ring heterocyclic molecules, C2H4O and C2H4S, by total and partial ion yield spectroscopy. Positive and negative ions have been collected as a function of photon energy around the C 1s and O 1s ionization thresholds in C2H4O, and around the S 2p and C 1s thresholds in C2H4S. We underline similarities and differences between these two analogous systems. We present a new assignment of the spectral features around the C K-edge and the sulfur L2,3 edges in C2H4S. In both systems, we observe high fragmentation efficiency leading to positive and negative ions when exciting these molecules at resonances involving core-to-Rydberg transitions. The system, with one electron in an orbital far from the ionic core, relaxes preferentially by spectator Auger decay, and the resulting singly charged ion with two valence holes and one electron in an outer diffuse orbital can remain in excited states more susceptible to dissociation. A state-selective fragmentation pattern is analyzed in C2H4S which leads to direct production of S2+ following the decay of virtual-orbital excitations to final states above the double-ionization threshold

A new approach to balance dental fear and anxiety by using BachTM Flower Therapy

Treatments in dentistry currently consist of an interdisciplinary approach, including (but not necessarily limited to) the holistic perspective. The different fields of allopathic and complementary medicine are used together to ensure not only a high-quality restorative treatment, but also to provide patients with psychological and emotional support. This perspective also applies to dental anxiety, which consists of complex (emotional, vegetative and psychomotor) manifestations. One of the most well-known complementary therapies for reducing dental fear and anxiety is BachTM Flower Therapy. Even if the mechanism of action of this therapy is not yet scientifically documented, notable results have been and continue to be reported in the literature in several clinical studies on patients with dental diseases. It is indicated for both adults and children, in the latter when they go through major biological changes, such as primary and permanent dentition. As a conclusion, BachTM flower therapy is effective and complementary to dental treatments applied to patients, by reducing stress, anxiety, as well as creating a climate of peace, trust and confidence, both for the patient and the doctor. In addition, it is a relatively accessible and cheap form of care, with no significant adverse effects noted so far

Periodontitis as a potential risk factor for premature delivery

Pregnancy is a particular period of time for a woman, so that it is important to accurately determine the impact of adjacent pathologies on the natural evolution of the nine months of pregnancy. Although there is still much to debate on the association between periodontal disease and pregnancy, the conclusion seems to remain the same: untreated periodontal pathology in pregnancy could have adverse consequences such as premature birth or low birth weight fetuses. Periodontopathies are introduced as risk factors, the novelty of the subject being the association between untreated periodontal pathology and the evolution of pregnancy. The affected periodontal tissue has the potential of releasing microorganisms that could colonize the placenta, ultimately having adverse consequences on the evolution of pregnancy, consequences such as premature birth or inadequate birth weight. The purpose of this review is to assess the association between periodontal disease and the negative consequences on pregnancy. Using databases such as PubMed, more than 1,500 articles were screened, including systematic reviews, case-control studies and prospective cohort studies assessing the association between periodontitis and pregnancy. Only 54 from the abovementioned papers were included in the final review

A pedunculated esophageal chondromatous hamartoma in a child

Esophageal tumors are uncommon in pediatric population and most of them are benign. Esophageal hamartomas have been reported extremely rare in children. These can present as intramural tumors of the esophageal wall or as polyps. Dysphagia is the main symptom described in their case, but other specific symptoms are also reported. Such symptoms encountered in clinical practice are represented by obstructive apnea episodes and bradycardia, poor weight gain, epigastric or retrosternal pain, hematemesis or melena, dysphonia or tracheal sounds. Diagnosis can be delayed due to the insidious onset and non-specific symptoms, therefore patient’s compliance to follow-up and broad, careful evaluation are mandatory. Preoperative imagistic assessment is extremely important for a precise definition of the tumor’s anatomical relations, especially when facing large tumors located in the posterior mediastinum. Herein we report a case of a large chondromatous polypoid hamartoma of the esophagus in a 9 years old boy, emphasizing over the diagnosis and surgical challenges we have met, along with comments on illustrative similar cases reported in the literature

Enhancing Brand Value of Modern Organizations through Digital Marketing Tools and Techniques: A Study on Top Ten Romanian Companies

The role and importance of the brand, in addition to better distinguishing the services or products of a modern organization from those of another, and to create a strong reputation, is also to protect the investments made in the name under which that organization carries on the business and to offer the premises for long-term profitability. The current paper discusses brand value related issues of modern organizations also in regard to their online presence strategies and makes a survey that analyses the top ten companies in Romania that have the strongest brand value. This analysis aims to identify the most important aspects that contribute in building the value of the respective brands from digital marketing tools and techniques (DMTTs) usage perspective. After processing and analysing the results, some observations are made in order to consolidate and improve the current methods of enhancing the value of a brand through DMTTs type of strategies

Klebsiella pneumoniae cryptogenic liver abscess and endophthalmitis – a case report and review of literature

Klebsiella pneumoniae has emerged as the predominant pathogenic agent of liver abscess in Asia, and the incidence is increasing worldwide. Hypervirulent strains are associated with septic metastatic dissemination in the eyes, lungs, and central nervous system, causing severe morbidity. We present the case of a 54year old man, with no previous comorbidities, admitted in emergency for the blind red painful eye. Further investigation documented septic endophthalmitis with transscleral extension and orbital cellulitis. Thoraco-abdominal computed tomography evidenced a hepatic abscess as the locus of the primary infection. Intravenous antibiotherapy with cefuroxime, followed by meropenem and vancomycin were efficient for managing the hepatic abscess. However, as the eyeball was perforated at the admission, evisceration was performed. The vitreous sample revealed Klebsiella pneumoniae, with a positive string test as the etiologic agent. The diagnostic and therapeutic management required a permanent collaboration between an ophthalmologist, infectious diseases specialist, surgeon, and radiologist

Recurrent pregnancy loss - a life changing condition for women

Recurrent pregnancy loss (RPL) is estimated to occur in 2.5% of women trying to conceive. Definition of RPL varies depending on used guideline. In Europe, RPL is defined as two or more lost pregnancies before 24 weeks’ gestation. Although many factors have been associated with a higher risk of recurrent miscarriage, the aetiology is unknown in about half of cases. Several factors have been related to recurrent pregnancy loss, such as: environmental, behavioral, genetic, endocrine, metabolic, autoimmune, anatomic, thrombophilia and male factor. Given the multitude of etiopathogenic factors, RPL frequently requires an interdisciplinary approach for diagnosis and treatment. By its repetitive nature, RPL represents a psychological trauma on the couple who wants to conceive a child. Consequently, empathy and support are also necessary to be integrated in the therapeutic approach in the case of couples with recurrent miscarriage
