A fundamental problem in materials science consists in establishing a relationship between the chemical composition, structure, and properties of materials. This issue can be solved through the study of multicomponent systems and the directed synthesis of promising compounds. Of practical interest here are active dielectrics that are based on complex oxide compounds, specifically molybdates. Among complex molybdates and tungstates, ternary caged molybdates of the following structural types are of greatest importance: nasicon, perovskite, langbeinite, etc. Due to their widely varying elemental and quantitative compositions, such molybdates are convenient models for structural and chemical design, as well as the establishment of “composition–structure– properties” genetic relationships. Bismuth-containing complex molybdate systems exhibit the formation of phases having ferro-piezoelectric, ionic, and other properties. In this work, the Rb2MoO4–Bi2(MoO4)3–Zr(MoO4)2 ter nary salt system was studied for the first time using the method of intersecting sections in the subsolidus region (450–650 ℃). To this end, quasibinary sections were identified; triangulation was performed. Ternary molybdates Rb5BiZr(MoO4)6 and Rb2BiZr2(MoO4)6,5 were formed in the system using a ceramic technology. These compounds are isostructural to the previously obtained REE molybdates (M5LnZr(MoO4)6) but contain trivalent bismuth instead of rare earth elements. The structure of Rb5BiZr(MoO4)6 was adjusted via the Rietveld refinement technique using the TOPAS 4.2 software package. The ternary molybdate crystallizes in a trigonal system, with the following unit cell parameters of the R`3c space group: a = 10.7756(2) and c = 39.0464(7) Å. According to the studies of thermal properties exhibited by M5BiZr(MoO4)6, these ternary molybdates undergo the first-order phase transition in the temperature range of 450–600 ºC. The IR and Raman spectra of M5BiZr(MoO4)6 reveal the crystallization of ternary molybdates in the R`3c space group. The conducted comparative characterization of M2MoO4–Bi2(MoO4)3–Zr(MoO4)2 phase diagrams suggests that the phase equilibria of these systems depend on the nature of molybdates of monovalent elements.

Abstract. Sulfuric acid is an important gas influencing atmospheric new particle formation (NPF). Both the binary (H2SO4-H2O) system, and the ternary system involving ammonia (H2SO4-H2O-NH3) may be important in the free troposphere. An essential step in the nucleation of aerosol particles from gas-phase precursors is the formation of a dimer, so an understanding of the thermodynamics of dimer formation over a wide range of atmospheric conditions is essential to describe NPF. We have used the CLOUD chamber to conduct nucleation experiments for these systems at temperatures from 208 to 248 K. Neutral monomer and dimer concentrations of sulfuric acid were measured using a Chemical Ionization Mass Spectrometer (CIMS). From these measurements dimer evaporation rates in the binary system were derived for temperatures of 208 and 223 K. We compare these results to literature data from a previous study that was conducted at higher temperatures but is in good agreement with the present study. For the ternary system the formation of H2SO4 • NH3 is very likely an essential step in the formation of sulfuric acid dimers, which were measured at 210, 223, and 248 K. We estimate the thermodynamic properties (dH and dS) of the H2SO4 • NH3 cluster using a simple heuristic model and the measured data. Furthermore, we report the first measurements of large neutral sulfuric acid clusters containing as many as 10 sulfuric acid molecules for the binary system using Chemical Ionization-Atmospheric Pressure interface-Time Of Flight (CI-APi-TOF) mass spectrometry.

Materials based on cerium oxides and REE are perspective for use in medicine, energy and mechanical engineering due to the uniqueness of their authorities. Stationary system diagrams are the physicochemical basis for the creation of such materials as solid electrolytes for fuel comics, oxygen gas sensors, catalyst carriers, protected coatings for alloys, etc. In this work, phase equilibria and structural transformations in the system CeO2-La2O3-Yb2O3 at a temperature of 1500 oС in all international concentrations are investigated by the methods of microstistructural and X - ray phase analysis. It is established that in the triple system CeO2-La2O3-Yb2O3 fields of solid solutions based on cubic (F) modification of the structure of the structure of fluorite CeO2, monoclinic (B) and cubic (C) modification of Yb2O3 and hexagonal (A) modification of La2O3 (R) are used, which crystallizes in a Perovski-type structure with rhombic curvatures. It was found that the rarefaction of CeO2 in the crystal lattice of the ordered phase with the structure of the perovskite type LaYbO3 (R) is ~ 3 mol. %. Isothermal review of the state diagram of the systems CeO2-La2O3-Yb2O3 at reveals the presence of two three-phase (F + C + R), (A + R + F) and five two-phase (A + F), (A + R), (R + C), (F + R), (F + C) regions.

The results of thermodynamic simulation of the manganese recovery in the CaO-SiO2-MgO-Al2O3-MnO-Fe2O3 system by carbon are presented. Parameters of the initial system are temperature range 1400-at a step of , a total pressure of 0.1 MPa, and N2. The composition of the oxide system is corresponded by the manganese ore (wt %) 1.1 MnO2, 44.3 MnO, 28.4 CaO, 9.3 SiO2, 5.4 MgO, 0.3 Al2O3, 11.2 Fe2O3 and silicomanganese slag. It contains (wt %) 16.3 MnO, 18.4 CaO, 52 SiO2, 7.8 MgO, 5.26 Al2O3, and 0.24 FeO. The amount of silicomanganese slag in the system was 0, 5, 12, and 25%. Carbon is used as a reducing agent. Its consumption is increased by 5% from the stoichiometry for the recovery of Fe and Mn and by 8% of the metal mass for the formation of iron, manganese, and silicon carbides. The simulation is carried out using HSC Chemistry 6.12 () software package. The thermodynamic characteristics of the Fe3C, Fe2O3, FeO, MnO2, Mn, Mn3C, Mn5C2, Mn7C3, Mn23C6, and SiC compounds existing in the database are refined. It was determined that an increase in the melt temperature from 1400 to increases the degree of manganese recovery (ηMn) for all compositions of the systems. An increase of the silicomanganese slag content in the mixture from 0 to 25% decreases ηMn from 89.3 to 85% at and from 95.8 to 91.5% at . The chemical composition of the high-carbon ferromanganese alloy is (wt %): 71.9-72.8 Mn, 16.6-17.9 Fe, 0.015-1.64 Si, and 9-. The simulation results can be used to develop a technology for producing a high-carbon ferromanganese when silicomanganese slag is involved in metallurgical processing.

The analysis of high temperature physical and chemical properties of molten salt system of aluminum electrolysis has guiding significance for practical production In this paper, the molecular dynamics calculation method was used to simulate the physical and chemical properties of 78%Na3AlF6-9.5%AlF3-5.0%CaF2-7.5%Al2O3 molten salt electrolyte system with Zr and B as additives at 1200K and standard atmospheric pressure. The effects of Zr and B elements on the radial distribution function, coordination number, diffusion coefficient, viscosity, and conductivity of electrolyte system were discussed in detail. The simulation results showed that Zr4+ weakened the connection between Al3+, while the addition of B3+ enhanced the interaction between Al3+, Na+, and F-. In the electrolyte system without impurities, the order of self-diffusion coefficient is Na+ > O2- > F- > Ca2+ > Al3+. And the addition of Zr4+ is conducive to the diffusion of ions in the system, while the addition of B3+ is not conducive to the diffusion of ions in the system. What’s more, the addition of Zr improves the conductivity of the system, while the addition of B reduces the conductivity of the system.

Abstract. Many years ago Mayaud (1965) suggested that a tilted, rather than symmetric, current system may be responsible for the form of daily magnetic variations near the focus of the current system. With arrays of magnetometer stations, both in Australia and in Europe, it is now demonstrated that such tilted systems do exist at certain times. At other times the magnetic variation near the focus is deformed by a previously reported extra morning current system which is apparently unconnected to the regular Sq system.

Abstract. Here I present a comparison between two of the most widely used reduced-complexity models for the representation of sediment transport and deposition processes, namely the transport-limited (or TL) model and the under-capacity (or ξ–q) model more recently developed by Davy and Lague (2009). Using both models, I investigate the behavior of a sedimentary continental system of length L fed by a fixed sedimentary flux from a catchment of size A0 in a nearby active orogen through which sediments transit to a fixed base level representing a large river, a lake or an ocean. This comparison shows that the two models share the same steady-state solution, for which I derive a simple 1D analytical expression that reproduces the major features of such sedimentary systems: a steep fan that connects to a shallower alluvial plain. The resulting fan geometry obeys basic observational constraints on fan size and slope with respect to the upstream drainage area, A0. The solution is strongly dependent on the size of the system, L, in comparison to a distance L0, which is determined by the size of A0, and gives rise to two fundamentally different types of sedimentary systems: a constrained system where L<L0 and open systems where L>L0. I derive simple expressions that show the dependence of the system response time on the system characteristics, such as its length, the size of the upstream catchment area, the amplitude of the incoming sedimentary flux and the respective rate parameters (diffusivity or erodibility) for each of the two models. I show that the ξ–q model predicts longer response times. I demonstrate that although the manner in which signals propagates through the sedimentary system differs greatly between the two models, they both predict that perturbations that last longer than the response time of the system can be recorded in the stratigraphy of the sedimentary system and in particular of the fan. Interestingly, the ξ–q model predicts that all perturbations in the incoming sedimentary flux will be transmitted through the system, whereas the TL model predicts that rapid perturbations cannot. I finally discuss why and under which conditions these differences are important and propose observational ways to determine which of the two models is most appropriate to represent natural systems.

Lifetime analyses in heavy flavour systems can provide excellent opportunities to make precision measurements of Standard Model (SM) parameters that probe for new physics. This thesis presents lifetime measurements from the Bd and Bs mesons to the charmless two-body hadron family of decays, known as B->hh, where h can be either a kaon or a pion. A particular interest is given to the Bs->KK decay channel. The Bs->KK channel is interesting as it decays into a CP even final state, with a small amount of CP violation predicted by the Standard Model. This can be quantified using the decay rate asymmetry parameter A Delta Gamma. The decay is also loop dominated, and thus sensitive to New Physics (NP) that could enter in these processes. These effects can be studied by constraining the values of the decay rate difference, Delta Gamma s, and A Delta Gamma from a lifetime measurement of the Bs->KK. A method used to measure the effective lifetime of the B->hh channels, which removes the acceptance bias induced by the event selection, is described. This includes fits to the invariant mass and reconstructed lifetime spectrums, together with the methods employed to determine the per-event acceptance functions from data and treatment of non-parametric backgrounds. The application of this method to two datasets is then presented. Both datasets are collected using a centre of mass energy sqrt{7 Tev} with the first dataset from the 2010 run comprising a total integrated luminosity of 37 inverse pb, and the second from the 2011 run comprising a total integrated luminosity of 1.0 inverse fb. The fit methods are verified using various techniques, primarily using a simplified MC simulation and full LHCb Monte Carlo (MC). The fit to the mass spectrum of the Bd->Kpi from the 2011 dataset is used both for the lifetime measurement, and for the normalisation in a search for the Bds->ppbar decay. As the details of the lifetime analysis methods are subtly different between datasets, the sources of uncertainty differ between the analyses. The lifetime measurement resulting from the 2010 dataset is found to be tau_{Bs->KK} = 1.440 +/- 0.096 ps stat +/- 0.008 ps syst. The resulting B->hh lifetimes, measured from the 2011 dataset are found to be tau_{Bs->KK} = 1.407 +/- 0.016 ps stat +/- 0.007 ps syst, tau_{Bd->Kpi} = 1.524 +/- 0.011 ps stat +/- 0.004 ps syst, tau_{Bs->piK} = 1.597 +/- 0.056 ps stat +/- 0.012 ps syst. These measurements are consistent with previous measurements, with the value of tau_{Bs->KK} measured from the 2011 dataset having a greater precision than the current world average. From this, we are able to directly measure the quantity A Delta Gamma for the first time, with the value evaluated found to be A Delta Gamma = -0.87 +/- 0.17 stat +/- 0.13 syst. Particle IDentification (PID) of the family of B->hh decays is crucial for distinguishing the many different final states that are kinematically similar. These final states tend to overlap in mass when reconstructed, providing considerable difficulties when making measurements with them. The Ring Imaging CHerenkov (RICH) detectors provide the experiment with PID capability, which allow high precision measurements from these channels to be made. During data taking periods, it is important to monitor the performance of the many subsystems that allow the RICH operations to run smoothly. Two studies are presented in this thesis that pertain specifically to RICH 2. The first studies the stability of the spherical and flat mirrors, using the Laser Alignment Monitoring System (LAMS). A direct correlation between observed movement and temperature is found, which is in the order 10-70 micro rad/K and agrees with estimates based on the expansion coefficients of materials and the mirror supports. This is an order of magnitude lower than the angular resolution of RICH 2, so does not affect the resolution or performance of the detector. The second study suggests an alternative method to constrain the refractive index of the RICH gas. This method allows for continuous monitoring of the refractive index, with a greater frequency in time than is currently available. The method is purely data driven and is found to be in agreement with the currently employed RICH method to within 1%.

This thesis is about evolving a control system for a snake called Transformer <-> #13. This is a mechanical snake with several body parts. The choise was to use a cellular genetic algorithm where each body part is a cell. These contain DNA, one ruleset for each degree of freedom in the joints, which decides how it will behave in relation to its neighbour body parts. Three different fitness functions have been implemented which each gives a distinct and different behaviour. The goal of the different fitness functions is; crawling far, rising high and making geometry. The crawling part was successfull, while the other two goals was much harder for the snake and didnt provide great results. Concluding that the snake is appropriate for crawling around and making an impression of different cubic forms. Which for artist purposes is adequate, but it fails on getting into specific shapes.

The aim of this research is to perform a thermodynamic analysis of an SOFe - gas turbine (GT) hybrid power plant, including economical aspect, so as to examine its appropriateness (through the study of several cases) for marine application on an LNG carrier. Provided the data concerning properties and costs of materials, the developed model is to fit for a wide range of parametric analysis of thermodynamic cycles. This prospect takes into the consideration that SOFe is a promising technology with lots of advantages in comparison to conventional marine combustion engines; it is much more efficient, friendlier to the environment, more fuel flexible and operates under high operating temperatures which enable a successful thermal integration with bottoming cycles (gas turbine cycles) in order to achieve a higher efficiency. In general terms, an LNG carrier has a high energy demand. Through this analysis, it is shown in certain extent the SOFe - GT system can be developed either for the main propulsion of the vessel or the APU (Auxiliary Power Unit). The latter is a more practical possible solution as it is of less exigent energy. The program used for this analysis is divided into two sections; the pre-reforming section and the electrochemical (SOFC) section together with the gas turbine including the cost model as well. Another issue which is examined in this thesis is the fluctuation of charter rates of a specific LNG carrier depending on the size of the investment. The height of the investment is defined by the power output of the SOFe installation. The final results give a theoretical and general idea of the way that this hybrid power plant could be exploited by an LNG carrier implying whether it can be preferred to the conventional combustion engines or not.

Ce travail évalue le potentiel des couches minces LSMO déposées sur substrat silicium comme détecteur de rayonnement à température ambiante, en exploitant la variation de sa résistance électrique. La fabrication de structures suspendues et les caractérisations électro-thermiques (R(T), conductance thermique, temps de réponse), optiques et les performances en bruit sont présentés. Des mesures optiques avec différentes sources de rayonnement (635 nm, 3,39 µm, corps noir, et faisceau synchrotron) ont été réalisées. Les performances obtenues sont très intéressantes car les puissances équivalentes de bruit (NEP) peuvent atteindre quelques pW·Hz-1/2 à 300 K. Les caractérisations optiques réalisées montrent que ces détecteurs sont au niveau de l'état de l'art. Le bolomètre est sensible dans ces différentes gammes alors que celui-ci n'était pas couplé à une antenne. Un modéle électro-thermique et des simulations éléments finis sont présentés, ils permettent de comprendre le comportement des bolomètres en fonction du point de fonctionnement choisi (courant de polarisation, température). Les constantes de temps thermique (de l’ordre de 1 ms) et les consommations électriques (quelques dizaines de μW) sont faibles. Ces performances sont très prometteuses comparativement à l’état de l’art des détecteurs non refroidis. Les applications envisagées sont celles nécessitant un faible nombre de détecteurs performants, dans la gamme infrarouge jusqu’au THz
This work evaluates the potential of LSMO thin films deposited on a silicon substrate as a radiation detector at room temperature, by exploiting the variation of its electrical resistance. The fabrication of suspended structures and electro-thermal (R(T), thermal conductance, response time) and optical characterizations are presented as well as and noise performance. Optical measurements with different radiation sources (635 nm, 3.39 μm, black body, and synchrotron beam) were performed. The obtained performances are very interesting because the noise equivalent power (NEP) can reach pW·Hz-1/2 to 300 K. The optical characterizations realized show that these detectors are at the state-of-the-art level. The bolometer is sensitive in these different ranges while it was not coupled to an antenna. An electro-thermal model and finite element simulations are presented, they make possible the understanding of the behaviour of the bolometers as a function of the chosen operating point (polarization current, temperature). The thermal time constants (around 1 ms) and the electrical consumptions (a few tens of μW) are low. These performances are very promising compared to the state-of-the-art of uncooled detectors. The applications envisaged are those requiring a small number of sensitive detectors, in the infrared range up to THz

With the increasing popularity of information technologies, many companies try to set up a virtual network in order to share their business information. The purpose of creating such a virtual network is to create a new knowledge base on the combination of the existing knowledge. Collaboration is very necessary in such a virtual network as crass-unit collaboration takes place when people from different units work together in cross-unit teams on a common task or provide significant help to each other. Recently, co-design is an emerging technology in the field of informatics. It is considered as the development of system thinking, and it is a collaborative designing process which recruits designers, researchers, stakeholders and others together. The purpose of this collaborative activity is to sole designing problems. Therefore, if we want to increase collaboration in a co-design process, we need to look at a ways of increasing the efficiency of collaboration. The rapid development of accessible, reliable, and user-friendly information technology offers improvements to traditional collaboration, and makes new approaches possible. Many platforms for the exchange of information such as the Internet, email, and video-conferencing are well established aids to collaborative activities. Therefore, my research investigates to create an efficient virtual network for a co-design process. In this research, I will try to investigate that what is the need of a virtual network for co-design process and what are those virtual network soft-wares which can help us in a co-design process. My research discussion is related to the theory of CSCW (Computer Supported cooperative work).

The startup of the Large Hadron Collider will allow scientists to probe energy scales that existed picoseconds after the Big Bang. Monte Carlo samples of many Standard Model processes are produced to simulate the conditions in the Compact Muon Solenoid detector. Data analysis techniques are developed to measure the cross section of the W Z --> 3l(e, [mu]) decay channel. The results are [sgima]all = 723.4 ± 27.6(stat.) ± 144.7(syst.) fb for integrated luminosity 1 fb-1. Cross section measurements deduced by our data analysis techniques agree with the theoretical predictions, [sigma] pred. all = 708 ± 26.6 fb. The selection of W Z --> 3l events gave 43.5 ± 6.6 signal events with 6.4 ± 2.5 background events, enough to claim an observation at the level of five standard deviations. The understanding of this process will aid in the search for the Higgs boson, as well as in the search for new physics in the early stages of the operation of the detector.

Main and connecting rod bearings along the crankshaft in a heavy-duty engine oil system requires efficient feed of oil flow to ensure the performance of lubrication, cooling and cleaning. The bearings and builded bearing models considered in this work are based on a Volvo 13L engine. Two main models to predict the oil flow in main and connecting rod bearings have been investigated using the system analysis software GT-SUITE. These two models are based on two numerical methods called the Mobility method and the Reynold's equation respectively. The main bearing and the connecting rod large end bearing loads calculated in the present work is similar to the reference bearing loads, especially for connecting rod large end bearing and at lower engine speeds. For higher engine speeds, the present load results are far off, compared to the reference load results. This difference at the higher engine speeds showed also an increased difference in the oil volume flow rates. But more information regarding the calculations of the reference loads is needed to analyze the differences further. Considering the "split lines", where the upper and the lower bearing shell meet, in the bearing models increased the oil volume flow rate with 13.3\% on average for the main bearing. Main bearing stand for 86\% of the total flow whilst connecting rod large end and small end bearing stand for the rest 13\% and 1\% of the total flow. The feed of oil to main bearing and connecting rod large end bearing appears continuously whilst the feed of oil to connecting rod small end bearing appears in the form of a few pulsations. Comparing to the numerical reference flow results, the results in this work are similar at high oil temperatures and at low engine speeds, otherwise the results are far off. Considering the Reynold's equation when predicting the oil volume flow rates in plain journal bearings is a more accurate way than using the Mobility method since it takes more specific geometrical irregularities into account. The oil volume flow rate for main bearing differ with 2.7\% on average when solving the Reynold's equation compared to the Mobility method.

Estudos funcionais anteriores identificaram um módulo cis-regulador (MCR) de 67 pb (-253/- 187) na região promotora do gene de pufe de DNA BhC4-1 que dirige a expressão do gene repórter na glândula anelar de Drosophila melanogaster. Uma análise bioinformática identificou 67 sequências de D. melanogaster que são similares a sequências contidas no MCR de glândula anelar. Uma das sequências identificadas reside em um fragmento genômico de 657 pb localizado aproximadamente 2500 pb à montante do CG13711, 400 pb à montante do CG12493, em uma região genômica que constitui um dos íntrons do CG32239 (Gef64C). A caracterização preliminar de três linhagens transformadas com a construção 657 pb-lacZ mostrou expressão do gene repórter no sistema traqueal de larvas e prépupas e no tórax de adultos. Baseado padrão de expressão promovido por este MCR, o mesmo foi denominado Traqueia-Tórax (TT). O principal objetivo do presente trabalho constituiu estender a caracterização molecular das linhagens da série TT-lacZ. Inicialmente embriões, larvas de primeiro, segundo e terceiro estádio, prépupas 0 h, 1 h e 2 h, pupas 24 h e adultos com 1, 3 e 5 dias foram investigados quanto ao padrão de expressão do repórter utilizando ensaio histoquímico que detecta atividade de ?-galactosidase. A expressão do gene repórter é inicialmente detectada no sistema traqueal durante o terceiro estádio larval e continua a ser detectada neste tecido em prépupas 0 h, 1 h e 2 h e pupas 24 h. Em adultos, a expressão do gene repórter é verificada nos músculos longitudinais dorsais em adultos de 3 e 5 dias. Uma vez que o MCR TT reside em uma região intergênica e a informação disponível sobre os CGs próximos ainda é escassa, não foi possível inferir qual dos CGs é regulado pelo MCR TT. Neste contexto, o padrão de expressão do RNAm do gene repórter lacZ e do CG13711, CG12493 e CG32239 foi investigado no sistema traqueal de larvas e prépupas e no tórax de adultos de uma das linhagens da série TT-lacZ utilizando RT-qPCR. Os níveis de expressão do RNAm lacZ aumentam cerca de 3 vezes em prépupas 0 horas, quando comparados com os níveis de expressão do RNAm lacZ presentes no sistema traqueal de larvas de terceiro estádio. Um padrão de expressão similar foi observado no caso do CG32239 e do CG13711. Nos tóraxes de adultos de 3 e 5 dias de idade os níveis de expressão do RNAm lacZ aumentam cerca de 37 vezes e 11 vezes, respectivamente, quando comparados aos níveis de expressão iv do RNAm lacZ presentes nos tóraxes de adultos de 1 dia. No tórax de adultos, o único CG que apresenta um padrão de expressão similar ao padrão de expressão de lacZ constitui o CG12493. Em conjunto, nós concluímos que o MCR TT promove um padrão dinâmico de expressão durante o desenvolvimento. Além disso, com base nos resultados de RT-qPCR, nós sugerimos que o MCR TT regula a expressão do RNAm do CG32239 no sistema traqueal durante a transição larva-prépupa e também a expressão do RNAm do CG12493 no tórax de adultos de 3 e 5 dias de idade. Além de estender a caracterização funcional de um novo MCR, nossos resultados também contribuem com novas informações acerca dos padrões de expressão no desenvolvimento de três CGs de D. melanogaster.
Previous functional studies identified in the DNA puff BhC4-1 promoter region a 67 bp (- 253/-187) cis-regulatory module (CRM) that drives reporter gene expression in the ring gland of D. melanogaster. A bioinformatics analysis identified 67 Drosophila melanogaster sequences that are similar to sequences contained in the ring gland CRM. One of the identified sequences resides in a 657 bp genomic fragment located about 2500 bp upstream CG13711, about 400 bp upstream CG12493, in a genomic region that constitutes one of the introns of CG32239 (Gef64C). The preliminary characterization of three transgenic lines transformed with a 657 bp-lacZ construct revealed reporter gene expression in the larval/prepupal tracheal system and in adult thorax. Based on the pattern of expression driven by this CRM we named it Trachea-Thorax (TT). The main goal of this work was to extend the molecular characterization of the lines of the TT-lacZ series. Initially ?-galactosidase histochemical assays were performed in embryos, first, second and third instar larvae, 0h, 1h and 2h prepupae, 24 h pupae and 1, 3 and 5 days old adults. Reporter gene expression is initially detected during the third larval instar in the tracheal system and continues to be detected in this tissue at 0 h, 1h and 2 h prepupa and, 24 h pupa. During the adult stage, reporter gene expression is verified in the dorsal longitudinal muscles of 3 and 5 days old adults. Since the TT CRM lies in an intergenic region and the available information about the nearby CGs is still scarce it was not possible to infer which of the CGs is regulated by the TT CRM. In this context, the mRNA pattern of expression of the lacZ reporter gene and of CG13711, CG12493 and CG32239 was investigated in the tracheal system of both larvae and prepupae and in adult thoraxes of one of the transgenic lines of the TT-lacZ series using RTqPCR. The lacZ mRNA expression levels increase about 3 times in 0 h prepupae when compared to the lacZ mRNA expression levels present in the tracheal system of third instar larvae. A similar pattern of expression was observed for both CG32239 and CG13711. In three and five days old adult thoraxes lacZ mRNA expression levels increase about 37 times and 11 times, respectively, when compared to lacZ mRNA expression levels present in one day old thoraxes. In the adult thorax, the only CG that presents a similar pattern of expression constitutes CG12493. Overall, we conclude that the TT CRM drives a dynamic pattern of ii expression throughout development. Additionally, based on RT-qPCR results, we suggest that the TT CRM regulates the expression of CG32239 mRNA in the tracheal system during the larvae to prepupae transition, as well as the expression of CG12493 mRNA in the thorax of 3 and 5 days old adults. Besides extending the functional characterization of a novel CRM our results also contribute new information about the developmental patterns of expression of three Drosophila melanogaster CGs.

The seismic resilience of new and existing structures is a key priority for the protection of human lives and the reduction of economic losses in earthquake prone areas. The modern seismic codes have focused on the upgrade of the structural performance of the new and existing structures. However, in many cases it is preferrable to mitigate the effects of the earthquakes by reducing the induced loads in the structures using seismic isolation and response control devices. The limited expertise in the selection and design of the appropriate system for new and existing structures is the main challenge for an extensive use of seismic isolation and response control systems in practice. This document aims to provide a practical guide by presenting a collection of the most commonly used seismic isolation and response control systems and a critical evaluation of the main characteristics of these systems. Comparisons of the key parameters of the design processes for new buildings with seismic isolation are presented, while the application of seismic isolation systems and response control systems for the retrofitting of existing structures is also examined, followed by various case studies from Greece, Japan, Mexico, New Zealand, and Turkey.

Koror Babeldaob Bridge, also called Koror Babelthuap Bridge or simply Koror Bridge, connects the islands of Koror and Babeldaob in the Republic of Palau. The design of the bridge began in 1974 and was based on the prevailing AASHO Standard Specifications at that time and was supplemented by ACI and CEB-FIP design recommendations on an as-needed basis. When the Koror Bridge was opened to traffic in April 1977, it was the world's longest concrete girder span. A few years later, the bridge began to deflect more than had been anticipated. The owner commissioned a Japanese engineering firm in 1985 and then a US engineering firm in 1993 to conduct in-depth investigations of the structure. Both firms came to the same conclusion that the bridge was structurally safe and that the excessive deflection was an unexplainable phenomenon. Nevertheless, in order to improve the driving quality of the bridge deck, the owner decided to repair the bridge. The repair scheme made changes to the structural system and added a large amount of post-tensioning force to the bridge. Unfortunately, less than three months after the repair, late in the afternoon on 26 September, 1996,nineteen and a half years after it was opened to traffic, the bridge collapsed. Thereafter, most of the documents were sealed as a result of litigation between the various parties and the debris was cleared. For a long time, it was impossible to study the facts surrounding the bridge's collapse. Only recently, through continuous probing by a group of engineers, were these documents made accessible to researchers.

Any struoture in navigable waters constitutes a hazard to shipping and is itself vulnerable to damage or destruction in the event of vessel collision. Worldwide vessel traffic and the average size of vessels continue to lncrease. At the same time, ever more bridges crossing navigable waterways are being planned and constructed, sometimes with inadequate navigation clearance and/or lnadequate protection. The objective of this publication is to provide information and guidelinesfor engineers charged with the planning and design of new bridges, navlgation channels, and prevention and protection measures. Lt offers advice on upgrading and retrofrtting existing bridges and navigation channels. And lt provides the means to evaluate the safety of bridges, vessels, persons and the environment. After reviewing some basics o! navigatlon and vessel traffic, and considering risk acceptance and collision risk, the publication examines vessel impact forces on bridges and proposes appropriate bridge design criteria. Prevention measures, such as regulations and management systems. And protectlon measures and systems are also described. Major international research projects have provided the analytical basis for the publication, including the development of vessel collision guide specific-atrons for the Federal Highway Administration in the USA and the vessel colllsion design crrteria developed for the Great Bell Crossing in Oenmark. Prepared by Ole Damgaard LARSEN, Chairman of the IABSE Working Group "Ship Collision with Bridges'', lhis 132 page publlcation is a must for any engineer dealing with structures in navigable waters.

Since the dawn of civilization, timber has been a primary material for achieving great structural engineering feats. Yet during the late 19th century and most of the 20th century it lost currency as a preferred material for construction of large and tall multi-storey building superstructures. This Structural Engineering Document (SED) addresses a reawakening of interest in timber and timber-based products as primary con-struction materials for relatively tall, multi-storey buildings. Emphasis throughout is on holistically addressing various aspects of performance of complete systems, reflecting that major gaps in knowhow relate to design concepts rather than technical information about timber as a material. Special con-sideration is given to structural form, fire vulnerability, and durability aspects for attaining desired building performance over lifespans that can be centuries long.

Society expects that buildings and other structures are safe for the people who use them or who are near them. The failure of a building or structure is expected to be an extremely rare event. Thus, society implicitly relies on the expertise of the professionals involved in the planning, design, construction, operation and maintenance of the structures it uses.Structural engineers devote all their effort to meeting society’s expectations effi ciently. Engineers and scientists work together to develop solutions to structural problems. Given that nothing is absolutely and eternally safe, the goal is to attain an acceptably small probability of failure for a structure, a facility, or a situation. Reliability analysis is part of the science and practice of engineering today, not only with respect to the safety of structures, but also for questions of serviceability and other requirements of technical systems that might be impacted by some probability.The present volume takes a rather broad approach to safety and reliability in Structural Engineering. It treats the underlying concepts of safety, reliability and risk and introduces the reader in a ﬁ rst chapter to the main concepts and strategies for dealing with hazards. The next chapter is devoted to the processing of data into information that is relevant for applying reliability theory. Two following chapters deal with the modelling of structures and with methods of reliability analysis. Another chapter focuses on problems related to establishing target reliabilities, assessing existing structures, and on effective strategies against human error. The last chapter presents an outlook to more advanced applications. The Appendix supports the application of the methods proposed and refers readers to a number of related computer programs.This book is aimed at both students and practicing engineers. It presents the concepts and procedures of reliability analysis in a straightforward, understandable way, making use of simple examples, rather than extended theoretical discussion. It is hoped that this approach serves to advance the application of safety and reliability analysis in engineering practice.The book is amended with a free access to an educational version of a Variables Processor computer program. FreeVaP can be downloaded free of charge and supports the understanding of the subjects treated in this book.

The material presented in the monograph shows the possibilities of continuous teaching of mathematics at school, namely, the significant potential of modern information and communication technologies, with the help of which it is possible to form elements of stochastic culture among students. Continuity in learning is considered from two positions: procedural and educational-cognitive. In addition, a distinctive feature of the book is the presentation of the digital transformation of general education as a way to overcome the "new digital divide". Methodological features of promising digital technologies (within the framework of teaching students the elements of the probabilistic and statistical line) that contribute to overcoming the "new digital divide": artificial intelligence, the Internet of Things, additive manufacturing, machine learning, blockchain, virtual and augmented reality are described. The solution of the main questions of probability theory and statistics in the 9th grade mathematics course is proposed to be carried out using a distance learning course built in the Moodle distance learning system. The content, structure and methodological features of the implementation of the stochastics course for students of grades 10-11 of a secondary school are based on the use of such tools in the educational process as an online calculator for plotting functions, the Wolfram Alpha service, Google Docs and Google Tables services, the Yaklass remote training, the Banktest website.<url>", interactive module "Galton Board", educational website "Mathematics at school".

Food production results from the activities of very complex national food systems. These systems are led by agriculture but comprise large and diverse industrial, distribution and trading activities that supply food to end consumers. These national systems are integrated through international trade into a powerful global food system that constitutes the main economic activity for 40% of the global population.The global food system must be able to provide quality food in sufficient quantities and at reasonable prices to satisfy the needs and expectations of all consumers. One of the greatest challenges in our days is developing balanced food systems, capable of responding to the particular needs of individual countries and regions, as well as to the global needs of humanity.An important first step in addressing this challenge was the Food Systems Summit convened by the Secretary-General of the United Nations in September 2021. On that occasion, the Western Hemisphere, in its role as the world’s major food exporter, had a significant participation in the deliberations and in building consensus, arguing in favor of designing rules and disciplines to improve international food trade.This book attempts to make a modest contribution, from a Latin American perspective, to the discussion and consensus building processes for the development of a balanced and effective global food system.

Die Europäische Wirtschafts- und Währungsunion (WWU) ist einer der Grundpfeiler der europäischen Integration. Seit dem 1. November 1999 nimmt die EU gegenüber den am Euroraum teilnehmenden Mitgliedstaaten die ausschließliche Zuständigkeit für die Währungspolitik wahr. Vorrangiges Ziel der Europäischen Zentralbank ist die Sicherung von hoher Preisniveaustabilität. Zugleich bestehen umfassende Verpflichtungen der Mitgliedstaaten im haushaltspolitischen Bereich, die in prozeduralen Vorgaben und inhaltlichen Beschränkungen der Staatsverschuldung zum Ausdruck kommen. Das bestehende System erfuhr durch die Finanz- und Schuldenkrise erhebliche Umgestaltungen, nicht zuletzt in Gestalt des Europäischen Stabilitätsmechanismus und der Europäischen Bankenunion. Die Corona Pandemie führte zu weiteren Neuerungen und ermöglichte der Union, sich erstmals umfassend selbst zu verschulden. Das neue Handbuch analysiert alle wichtigen rechtlichen Rahmenbedingungen der WWU vor dem Hintergrund der Krisen und Reformen der letzten Jahre. Breiten Raum nehmen Darstellungen des aktuellen Rechtsrahmens zur Sicherung und Stabilisierung des Systems (Autonomie der Haushaltspolitik, Stabilitäts- und Wachstumspakt, Fiskalvertrag, Europäischer Stabilitätsmechanismus), der rechtlichen Anforderungen an die Geldpolitik der EZB und der Bankenunion ein. Es vereint Beiträge nicht von rechtswissenschaftlicher Seite, sondern auch aus Sicht des ökonomischen Schrifttums. Schwerpunkte Entwicklungsgeschichte der WWU System der WWU Gemeinwohlfunktionen der WWU, Marktwirtschaft und Systementscheidungen, Solidarität in der Eurozone Das Recht der Wirtschaftsunion: wirtschaftspolitische Koordinierung, Stabilitäts- und Wachstumspakt, Fiskalvertrag Staatsfinanzierung und Notfallmechanismen: Autonomieprinzip, Haushaltskontrolle und Europäischer Stabilitätsmechanismus, Emergency Liqudity Assistance Das Recht der Bankenunion: Europäische Bankenaufsicht, Bankenabwicklung und Einlagensicherung Das Recht der Währungsunion: ESZB, Mandat der EZB, Geldpolitik, Währungsrecht, Rechtsschutz Die Autoren Prof. Dr. Roland Broemel, M.Sc.; Prof. em.

<div class="section abstract"><div class="htmlview paragraph">Typical two-site storage-based SCR plant models in literature consider NH3 stored in the first site to participate in NH3 storage, NOx conversion and second site to only participate in NH3 storage passively. This paper focuses on quantifying the impact of stored NH3 in the second site on the overall NOx conversion for an ultra-low NOx system due to intra site NH3 mass transfer. Accounting for this intra site mass transfer leads to better prediction of SCR out NH3 thus ensuring compliance with NH3 coverage targets and improved dosing characteristics of the controller that is critical to achieving ultra-low NOx standard. The stored NH3 in the second site undergoes mass transfer to the first site during temperature ramps encountered in a transient cycle that leads to increased NOx conversion in conditions where the dosing is switched off. The resultant NH3 coverage fraction prediction is critical in dosing control of SCR. This phenomenon is evaluated and quantified with different aging conditions, where the increased second site storage and reduced standard SCR activity due to hydrothermal aging leads to further increase in the reported phenomena. Although this phenomenon was observed for both light-off SCR (Lo-SCR) and downstream SCR based on analysis of the data, the impact on Lo-SCR performance was found to be higher compared to the downstream system due to the transient thermal conditions and higher temperatures experienced by the Lo-SCR system. This mass transfer mechanism also plays a role in determining NH3 slip characteristics of Lo-SCR for real world conditions where the gradual transfer of NH3 in the axial direction leads to NH3 slip. This phenomenon is demonstrated using experimental data collected on a production engine for a set of HFTP, CFTP, RMC and LLC cycles</div></div>

The characteristics and experiences of the gas turbine interactive design system, TDSYS, are described. The design of high performance advanced gas turbines requires complex trade-off analyses for optimization and hence it is necessary to use a highly efficient and accurate computerised integrated design system to complete the laborious design jobs in a short time. TDSYS is an interactive design system which makes extensive use of computer graphics and enables the designers to complete a gas turbine blade design systematically in a very short time. TDSYS has been developed and continuously improved over a period of ten years. The system has been used for the complete and retrofit design of many gas turbines including Mitsubishi MW701 and AGTJ-100A which is a high efficiency reheat gas turbine now being developed under a Japanese national project. In this paper, typical design samples of high temperature turbines are also presented.

<div class="section abstract"><div class="htmlview paragraph">This work is a part of medium-duty Low NOx technology development project with a focus on evaluating a combination of engine and advanced aftertreatment for 0.02 g/bhp-hr NOx regulation proposed by CARB (California air resource board). In this project, a control oriented chemical kinetics model of SCR (Selective catalytic reduction) was used in the aftertreatment controller that is susceptible to performance degradation due to hydrothermal and chemical aging. This paper focuses on modeling the NOx conversion and NH3 storage characteristics using a controls oriented SCR plant model which is further used for a model-based urea dosing scheme. A set of steady state reactor tests were used to calibrate the SCR performance at degreened, hydrothermal only and hydrothermal + chemical aging conditions and also to determine inhibition factors related to aging. The resultant model is capable of simulating SCR performance deterioration such as a reduction in NOx conversion and NH3 storage. A non-linear aging profile was observed for Lo-SCR and downstream SCR showing a change in the NOx conversion in the aged system when compared to a degreened system. Upon chemical aging further deterioration of low temperature performance was observed. This aging phenomenon impacts the dosing control strategy of the system. The results on controller performance for a set of Heavy Duty Federal Test Protocol(FTP), Ramp Modal Cycle (RMC), and Low Load Cycle (LLC) are presented.</div></div>

This paper presents the results of a project targeted at developing cost effective power plant concept with integrated Coal Gasification System (CGS) and with Compressed Air Energy Storage (CAES) plant. The developed concepts, denoted as CGS/CAES, provide for continuous operation of CGS and the reheat turboexpander train which are high temperature components, thus improving their operation and extending life resource. A parametric thermodynamic analysis is performed for several CGS/CAES concepts differentiated by their turbomachinery parameters, CGS arrangements, operating cycles, and hours of daily generation. A qualitative cost estimate is made using a variety of sources including published EPRI reports and extensive in-house cost data. A technical and cost comparison is made to the Integrated Gasification Combined Cycle (IGCC) plant.

<div class="section abstract"><div class="htmlview paragraph">Thousands die or are injured each year in automobile crashes. Reducing the number of these tragedies requires reframing our approach to vehicle- and human-based transportation mobility and depends on whether the mobility industry and individual human drivers take a more aggressive approach to saving lives and preventing injuries. Bringing automated driving systems technologies into the advanced driver assist systems (ADAS) and connected vehicle space will help humans drive more safely and better prepare us for automated vehicles (AVs). </div><div class="htmlview paragraph">Reducing Human Driver Error and Setting Realistic Expectations with Advanced Driver Assistance Systems discusses the recent Partnership for Analytics Research in Traffic Safety report which shows that ADAS can indeed work. The path forward requires combining ADAS and ADS implementation with infrastructure engineering, law enforcement, education, emergency response, and public policy, with the goal of reaching zero deaths and serious injuries. It also requires fully embracing the US Department of Transportation Federal Highway Administration’s Safe System approach, backed by the addition of public policies that incorporate and expand ADAS’s role in achieving that safe system.</div><div class="htmlview paragraph"><a href="https://www.sae.org/publications/edge-research-reports" target="_blank">Click here to access the full SAE EDGE</a>TM<a href="https://www.sae.org/publications/edge-research-reports" target="_blank"> Research Report portfolio.</a></div></div>

<div class="section abstract"><div class="htmlview paragraph">Modern in-vehicle experiences are brimming with functionalities and convenience driven by automation, digitalization, and electrification. While automotive manufacturers are competing to provide the best systems to their customers, there is no common ground to evaluate these in-vehicle experiences as they become increasingly complex. Existing automotive guidelines do not offer thresholds for cognitive distraction, or—more appropriately—“disengagement.” What can researchers can do to change this?</div><div class="htmlview paragraph">Evaluation of the In-vehicle Experience discusses acceptable levels of disengagement by evaluating the driving context and exploring how system reliability can translate to distraction and frustration. It also covers the need to test systems for their complexity and ease of use, and to prevent users from resorting to alternative systems while driving (e.g., smartphones). It highlights the value in naturalistic data generation using vehicles already sold to customers and the issues around privacy and trust concerning such methods. Lastly, it talks about the opportunities and challenges behind developing automated testing methods for in-vehicle experiences that simulate human behavior and how to shorten evaluation timelines to enabling a much larger scale of systems testing.</div><div class="htmlview paragraph"><a href="https://www.sae.org/publications/edge-research-reports" target="_blank">Click here to access the full SAE EDGE</a>TM<a href="https://www.sae.org/publications/edge-research-reports" target="_blank"> Research Report portfolio.</a></div></div>
