Analysis of the Connecting Zone between Consecutive Sections in Distillation Columns Covering Multiple Feeds, Products and Heat Transfer Stages

In the present work, we provide a systematic analysis about all tine streams involved in the zone connecting two consecutive sections for the design of distillation columns with different thermal feed conditions, product extractions and heat additions or withdrawals. This analysis allows a better understanding of what happens on a feed or side draw (of mass or energy) stage, what compositions are or are not in equilibrium, and the impact on internal liquid and vapor flows.

A Construction Management Framework for Mass Customisation in Traditional Construction

A Mass Customisation model is discussed as a competitive positioning strategy in the marketplace adding value to the customer’s end-use. It includes the user as part of the construction process responding to the customer’s demands and wishes. To the present day, almost all proposals for Mass Customisation have been focused on the design phase and single family houses. The reality is that the processes carried out in the work execution are so inefficient that the costs of the Mass Customisation models are assumed by the customer and they do not offer solutions that support the change management. Furthermore, this inefficiency often makes Mass Customisation unfeasible in terms of deadlines and site management. Therefore, the present proposal focuses on achieving the paradigm of Mass Customisation in the traditional residential construction complementary to the existing proposals in the design phase. All this through the proposal of a framework for the integral management in the work execution, which will address change management introduced by the users offering an efficient and productive model that reduces costs in the process. This model will focus on the synergy between different strategies, techniques and technologies currently used in the construction management (such as Lean Construction or Six Sigma), together with, other strategies and technologies that have proven to be valid solutions in other fields (such as Business Process Management, Service Oriented Architecture, etc.).

A new survey of cool supergiants in the Magellanic Clouds

Aims. In this study we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end of the brightness distribution of these stars, building a more representative dataset with which to extrapolate their behaviour to other Galactic and extra-galactic environments. Methods. We select candidates using only near infrared photometry, and with medium resolution multi-object spectroscopy, we perform spectral classification and derive their line-of-sight velocities, confirming the nature of the candidates and their membership in the clouds. Results. Around two hundred new red supergiants have been detected, hinting at a yet to be observed large population. Using near- and mid-infrared photometry we study the brightness distribution of these stars, the onset of mass-loss, and the effect of dust in their atmospheres. Based on this sample, new a priori classification criteria are investigated, combining mid- and near-infrared photometry to improve the observational efficiency of similar programs to this.

Late-Holocene Mass Movements in High Arctic East Lake, Melville Island (Western Canadian Arctic Archipelago)

East Lake, located at Cape Bounty (Melville Island, Canadian High Arctic), was mapped using a high-resolution swath bathymetric sonar and a 12 kHz sub-bottom profiler, allowing for the first time the imaging of widespread occurrence of mass movement deposits (MMDs) in a Canadian High Arctic Lake. Mass movements occurred mostly on steep slopes located away from deltaic sedimentation. The marine to lacustrine transition in the sediment favours the generation of mass movements where the underlying massive mud appears to act as a gliding surface for the overlying varved deposits. Based on acoustic stratigraphy, we have identified at least two distinct events that triggered failures in the lake during the last 2000 years. The synchronicity of multiple failures and their widespread distribution suggest a seismic origin that could be related to the nearby Gustaf-Lougheed Arch seismic zone. Further sedimentological investigations on the MMDs are however required to confirm their age and origin.

The EU’s Paradoxical Efforts at Tracking the Financing of Terrorism: From criticism to imitation of dataveillance. CEPS Paper in Liberty and Security No. 56, August 2013

In July 2011, the European Commission published a Communication aimed at setting out different options for establishing a European terrorist finance tracking system (TFTS). The Communication followed the adoption of the EU-US agreement on the US Terrorist Finance Tracking Program (TFTP) in 2010. The agreement concluded various series of national, European and transatlantic negotiations after the disclosure through public media of the US TFTP in 2006. This paper takes stock of the wide range of controversies surrounding this security-focused programme with dataveillance capabilities. After stressing the impact of the US TFTP on international relations, the paper argues that the EU-US agreement primarily has the effect of shifting information-sharing practices from the justice/judicial/penal/criminal investigation framework into the security/intelligence/administrative/prevention context as the main rationale. The paper then questions the TFTP-related conception of mass intelligence through large-scale databases and transnational communication of bulk data in the name of targeted surveillance. Following an examination of the project creating an EU system equivalent to the TFTP, the paper emphasises the fundamental paradox of transatlantic security matters, in which European criticism of American programmes tends to be ultimately translated into EU imitation of US dataveillance practices.

The Economic Basis of Attitudes towards the European Community: Familiarity Breeds Content. Institute for Advanced Studies Political Science Series, 12 April 1994

The purpose of this paper is to analyse the economic basis of mass support for, and opposition to the European Community. In other words the main question is: to what extent, and in what ways, is popular support or opposition to the EC dependent upon economic circumstances and considerations? Behind this research question lies the matter of the legitimacy of the EC in the eyes of citizens across Europe. In some respects the results of this study are frustrating and inconclusive. In other respects, however, the results suggest some clear generalizations and conclusions. First, we have found rather little evidence that the EC or European unification are evaluated in primarily economic terms. Secondly, support seems to be associated more strongly with social and attitudinal variables of a non-economic kind. Thirdly, the figures suggest that diffuse and somewhat idealistic reasons for supporting unification and EC membership tend to outweigh more specific reasons. Fourthly, a solid foundation of inertia, custom, and national tradition seem to maintain support and make it grow.

Public feeling in Ukraine ahead of the parliamentary election. OSW Commentary No. 89, 2012-07-12

After two and a half years under President Viktor Yanukovych and the Party of Regions, the overwhelming majority of Ukrainians are dissatisfied with the state the country’s economy is currently in and the direction it has been developing in. There has also been a significant drop in stability and social security with the general public increasingly feeling that the government has little interest in their problems. Only 16% of Ukrainians believe that the current government has performed better than their predecessors, although overall confidence in both the ruling party and the opposition remains low. Nonetheless, falling support for the president and the Cabinet does not seem to have translated into greater popularity for the country’s opposition parties; these currently enjoy the confidence of only a quarter of the electorate. The clear lack of credibility for politicians on either side of the political spectrum, coupled with an almost universal preoccupation with the bare necessities of life, has shifted the political processes in Ukraine further down the agenda for the majority of Ukrainians. Ukraine’s poor economic performance, which over the last two years has been addressed through a series of highly unpopular economic reforms, has resulted in a growing mood of discontent and increased civil activity, with the Ukrainian people reporting a greater willingness than ever to join protests on social issues. Most of them, however, have shown much less interest in political rallies. This is likely to stem from low levels of trust in the opposition and the general belief that opposition politicians are not a viable alternative to the current government. One may therefore assume that there will be little public scrutiny of the parliamentary election scheduled for 28 October, and that the likelihood of mass demonstrations during it is low. However, in the event of large-scale vote rigging and a dismissive response from the government, spontaneous unsanctioned rallies cannot be ruled out. What is more likely, however, is a series of protests after the elections, when the already difficult economic situation is further exacerbated by a predicted rise in the price of gas for Ukrainian households and a possible move to devalue the Ukrainian hryvnia.

Egypt: Changes and Challenges of Political Transition. MEDPRO Technical Report No. 4/May 2011

Hosni Mubarak’s regime and its power system enjoyed remarkable stability for over 30 years. On 11 February 2011, after 18 days of mass protests, the Egyptian president was forced to step down, revealing the unsustainability of the political and economic system that had ensured his continuity for so long. While the revolution of January 25th led to a major success – the fall of Hosni Mubarak – Egypt’s political future is still opaque and exposed to a number of risks. This paper first highlights the factors underpinning the former stability of Mubarak’s regime; it then assesses the causes of its underlying unsustainability, leading to the anti-government popular mobilisation in January-February 2011 and the removal of Mubarak; finally the paper evaluates the prospects for a genuine democratic transition in Egypt, by looking at the main political and socio-economic challenges facing the country.

Growth, survival, gene expression, microbiota and tryptic activity during feeding of Scophthalmus maximus first feeding larvae with beta-glucan (MacroGard)

Reflecting the natural biology of mass spawning fish aquaculture production of fish larvae is often hampered by high and unpredictable mortality rates. The present study aimed to enhance larval performance and immunity via the oral administration of an immunomodulator, beta-glucan (MacroGard®) in turbot (Scophthalmus maximus). Rotifers (Brachionus plicatilis) were incubated with or without yeast beta-1,3/1,6-glucan in form of MacroGard® at a concentration of 0.5 g/L. Rotifers were fed to first feeding turbot larvae once a day. From day 13 dph onwards all tanks were additionally fed untreated Artemia sp. nauplii (1 nauplius ml/L). Daily mortality was monitored and larvae were sampled at 11 and 24 dph for expression of 30 genes, trypsin activity and size measurements. Along with the feeding of beta-glucan daily mortality was significantly reduced by ca. 15% and an alteration of the larval microbiota was observed. At 11 dph gene expression of trypsin and chymotrypsin was elevated in the MacroGard® fed fish, which resulted in heightened tryptic enzyme activity. No effect on genes encoding antioxidative proteins was observed, whilst the immune response was clearly modulated by beta-glucan. At 11 dph complement component c3 was elevated whilst cytokines, antimicrobial peptides, toll like receptor 3 and heat shock protein 70 were not affected. At the later time point (24 dph) an anti-inflammatory effect in form of a down-regulation of hsp 70, tnf-alpha and il-1beta was observed. We conclude that the administration of beta-glucan induced an immunomodulatory response and could be used as an effective measure to increase survival in rearing of turbot.

Age models and sedimentation rates of sites in the tropical Atlantic

Late Pleistocene signals of calcium carbonate, organic carbon, and opaline silica concentration and accumulation are documented in a series of cores from a zonal/meridional/depth transect in the equatorial Atlantic Ocean to reconstruct the regional sedimentary history. Spectral analysis reveals that maxima and minima in biogenous sedimentation occur with glacial-interglacial cyclicity as a function of both (1) primary production at the sea surface modulated by orbitally forced variation in trade wind zonality and (2) destruction at the seafloor by variation in the chemical character of advected intermediate and deep water from high latitudes modulated by high-latitude ice volume. From these results a pattern emerges in which the relative proportion of signal variance from the productivity signal centered on the precessional (23 kyr) band decreases while that of the destruction signal centered on the obliquity (41 kyr) and eccentricity (100 kyr) periods increases below ~3600-m ocean depth.

Microsatellite genotyping of Mediterranean population of Ircinia fasciculata and Ircinia variabilis

Recent episodes of mass mortalities in the Mediterranean Sea have been reported for the closely related marine sponges Ircinia fasciculata and I. variabilis, which live in sympatry. In this context, the assessment of the genetic diversity, bottlenecks and connectivity of these sponges has become urgent in order to evaluate the potential effects of mass mortalities on their latitudinal range. Our study aims to establish 1.) the genetic structure, connectivity, and signs of bottlenecks across the populations of I. fasciculata, and 2.) the hybridization levels between I. fasciculata and I. variabilis. To accomplish the first objective, 194 individuals of I. fasciculata from 12 locations across the Mediterranean were genotyped at 14 microsatellite loci. For the second objective, mitochondrial cytochrome c oxidase subunit I sequences of 16 individuals from both species were analyzed along with genotypes at 12 microsatellite loci of 40 individuals coexisting in 3 Mediterranean populations. We detected strong genetic structure along the Mediterranean for I. fasciculata, with high levels of inbreeding in all locations and bottleneck signs in most locations. Oceanographic barriers like the Almeria-Oran front, North-Balearic front, and the Ligurian-Thyrrenian barrier seem to be impeding gene flow for I. fasciculata, adding population divergence to the pattern of isolation by distance derived from the low dispersal abilities of sponge larvae. Hybridization between both species occurred in some populations, which might be increasing genetic diversity and somewhat palliating the genetic loss caused by population decimation in I. fasciculata

Sample information and classification of lower Miocene gravity-flow types of sediment core CRP-1 (Table 1)

Nineteen samples of the Cape Roberts-1 drillcore were taken from Miocene- age deposits, from 90.25 - 146.50 metres below seafloor (mbsf) for thin section and laser grain-size analysis. Using the grain-size distribution, detailed core logging, X-radiography and thin-section analysis of microstructures, coupled with a statistical grouping of the grain-size data, three main styles of gravity-flow sedimentation were revealed. Thin (centimetre-scale) muddy debris-flow deposits are the most common and are possibly tirggered by debris rain-out from sea-ice These deposits are characterised by very poorly sorted, faintly laminated muddy sandstones with coarse granules toward their base. Contacts are gradational to sharp. Variations on this style of mass-wasting deposit are rhythmically stacked sequences of pebbly-coarse sandstones representing successive thin debris-flow events. These suggest very high sedimentation rates on an unstable slope in a shallow-water proximal glacimarine environment. Sandy-silty turbidites appear more common in the lower sections of the core, below approximately 141.00 mbsf, although they occur occasionally with the debris flow deposits The turbidites are characterised by inversely to normally graded, well-laminated siltstones with occasional lonestones, and represent a more distal shallow-water glacimarine environment.
