Cost Effective CO2 Reduction in the Iron & Steel Industry by Means of the SEWGS Technology: STEPWISE Project

In the STEPWISE project, the Sorption Enhanced Water-Gas Shift (SEWGS) technology for CO2 capture is brought to TRL6 by means of design, construction, operation and modelling a pilot installation in the Iron and Steel industry using Blast Furnace Gas (BFG). This advanced CO2 removal technology makes use of regenerative solid adsorbents. The STEPWISE project represents the essential demonstration step within the research, development and demonstration trajectory of the SEWGS technology. This project will further reduce the risks associated with scaling up the process

Conceptual design of the AE481 Demon Remotely Piloted Vehicle (RPV)

This project report presents a conceptual design for a high speed remotely piloted vehicle (RPV). The AE481 Demon RPV is capable of performing video reconnaissance missions and electronic jamming over hostile territory. The RPV cruises at a speed of Mach 0.8 and an altitude of 300 feet above the ground throughout its mission. It incorporates a rocket assisted takeoff and a parachute-airbag landing. Missions are preprogrammed, but in-flight changes are possible. The Demon is the answer to a military need for a high speed, low altitude RPV. The design methods, onboard systems, and avionics payload are discussed in this conceptual design report along with economic viability

A SÍNDROME DE TURNER EM ODONTOLOGIA

The Turner's syndrome (TS) was firstly described by Ulrich and Turner on 1938, and represents one of the most frequently chromosomic aberrations. l1's characterized by the presence of only one functional X chromosome. The other sexual chromosome doesn't exist or is abnormal (HALL and LOPEZ-RANGEL, 1995, cited by LOPEZ et aI., 2002). The most common kariotype is the 45,X, which is present in 40% to 60% of the patients with this pathology. This syndrome characteristic are gonadal disgenesis, puberal development delay, primary amenorrhea, sterility, wide chest, short and/or winged neck, cubitus valgus, anterior open bite, reduction of the length of pre-molar roots, among others. The present article is about a clinical case of a patient with Turner's Syndrome, examined at the Applied Stomatology lecture, at Universidade Federal do Paraná, and the implications of this syndrome on bucal health and also the importance of an adjusted prophylactic treatment. Key words: Dentistry; Turner's Svndrome.    A Síndrome de Turner (ST) foi descrita primeiramente por Ulrich e Turner em 1938, e representa uma das mais freqüentes aberrações cromossômicas.

As características dessa síndrome são disgenesia gonadal, atraso no desenvolvimento puberal, amenorréia primária, esterilidade, peito largo, pescoço curto e/ou alado, cubitus valgus, mordida aberta anterior, diminuição do comprimento das raízes de pré-molares, entre outras. O presente artigo trata-se de um relato de caso clínico de uma paciente com Síndrome de Turner atendida na Disciplina de Semiologia Aplicada na Universidade Federal do Paraná e das implicações desta síndrome sobre a saúde bucal e, também, a importância de um tratamento profilático adequado. Palavras-chave: Odontologia; Síndrome de Turner.

Enhanced hydrogen production from thermochemical processes

To alleviate the pressing problem of greenhouse gas emissions, the development and deployment of sustainable energy technologies is necessary. One potentially viable approach for replacing fossil fuels is the development of a H2 economy. Not only can H2 be used to produce heat and electricity, it is also utilised in ammonia synthesis and hydrocracking. H2 is traditionally generated from thermochemical processes such as steam reforming of hydrocarbons and the water-gas-shift (WGS) reaction. However, these processes suffer from low H2 yields owing to their reversible nature. Removing H2 with membranes and/or extracting CO2 with solid sorbents in situ can overcome these issues by shifting the component equilibrium towards enhanced H2 production via Le Chatelier's principle. This can potentially result in reduced energy consumption, smaller reactor sizes and, therefore, lower capital costs. In light of this, a significant amount of work has been conducted over the past few decades to refine these processes through the development of novel materials and complex models. Here, we critically review the most recent developments in these studies, identify possible research gaps, and offer recommendations for future research
