Improvised explosive devices: assessing the global risk for use in terrorism
Creators: name: Santaspirt, Michael
Publisher: name: No Publisher Supplied
Year: 2020

description: The purpose of this study is to investigate the risk of Improvised Explosive Device (IED) employment at the national level, the subnational level, and the street level, and to investigate innovative applications of Risk Terrain Modeling for IED risk analyses across these different levels of study. This study utilizes three separate applications of the Risk Terrain Modeling technique to determine the risk of IED emplacement at three separate analysis extents. Each level of analysis utilizes Geographic Information Systems to build composite risk maps from different types of risk factors that are associated with IED emplacement. Multivariate regression analysis is used to determine the association and significance of the risk factors as they relate to the outcome events. Composited global level risk factors associated with permissive environments are positively associated with increased IED emplacements. Countries at highest risk of IED emplacements, as determined by the global level model, can be composited with areas of operation for terrorist groups and densely populated areas to identify microplaces for further study. Those microplaces can be assessed for risk using RTMDx. The present study established a link between country level risk factors related to permissive environments enabled by state fragility and IED emplacements at the street level. As such, there are policy implications for strategic action to reduce state fragility and the establishment of permissive environments to curtail explosive violence. Furthermore, the identification of risky areas for IED emplacement can drive risk reduction techniques at all three levels of analysis.

description: Violence and periphery have always been central issues and useful key-concepts to understand Latin-American history transformations. This paper aims to analyse the representation of Mexicans’ body in United States, since the beginning of the Twentieth century until the Great Depression, and its role in defining the deportation inside the historical context of transformation of sovereignty. After 1929 crisis, the deportation of thousands of persons is the first massive expulsion of migrants supported by the U.S. government, a political practice that will lead to several consequences in the history of Mexico and its relation with U.S.A., besides changing completely the face of the frontier and migration itself.
description: Le tematiche della violenza e della periferia sono sempre state centrali nella storia latinoamericana, come chiave teorica per comprendere le sue trasformazioni. Questo articolo intende analizzare la rappresentazione del corpo dei messicani negli Stati Uniti, dall’inizio del Novecento fino alla Grande Depressione, e il ruolo che essa ha avuto nel definire la deportazione nel contesto storico di trasformazione della sovranità. Dopo la crisi del 1929, la deportazione di migliaia di persone costituisce il primo caso in cui il governo statunitense sostiene un’espulsione massiva di migranti, una pratica politica che porterà a numerose conseguenze nella storia del Messico e della sua relazione con gli U.S.A., oltre a cambiare completamente il volto della frontiera e quello della migrazione stessa.

description: Biosolids are defined as appropriately treated sewage sludge which consists of organic slurry residue derived from wastewater treatment processes. The sustainable usage of waste materials such as biosolids in engineering applications is of social and economic benefit to industrialized nations. Due to the shortages of natural mineral resources and increasing waste disposal costs, recycling solids wastes has become significant in recent years. This thesis presents research on the geotechnical properties of biosolids and investigates their sustainable usage as an embankment fill material, Field sampling of biosolids was conducted at three stockpiles at Biosolids Stockpile Area, Western Treatment Plant in Melbourne. An extensive suite of geotechnical laboratory tests were undertaken on untreated biosolids and biosolids stabilised with various additives. The geotechnical laboratory tests undertaken included index tests as well as more detailed tests. These tests included consolidation, triaxial, particle density, particle size analysis, Atterberg limits, compaction, California bearing ratio (CBR), hydraulic conductivity tests on untreated and well stabilised with admixtures such as lime, cement, bauxsol and fly-ash were determined and analysed in this research study. The Plaxis finite element analysis software was used to analyse the behaviour of various heights of embankments using stabilised biosolids with lime, cement, bauxsol and flyash. The primary, secondary and also the creep settlement were determined from the finite element analysis and analysed. In addition to the primary and secondary settlement, biodegradation settlement of the biosolids were also analysed by adapting theories that are presently used for landfills. As biodegradation is sensitive to pH values of the biosolids, a sensitivity analysis was undertaken by varying the pH value of the untreated biosolids and also the stabilised biosolids with admixtures. The laboratory testing results indicate that the biosolids stabilised with the required proportions of additives possess sufficient shear strength and bearing capacity to make them suitable for use as fill material. The results of the finite element analysis agree well with the laboratory results and indicate that biosolids, when stabilised with additives to the required percentages, can be used as stabilised fill in embankments

description: En este ensayo propongo una interpretación de Lumpérica (1983) de la novelista chilena Diamela Eltit como respuesta estética a las estrategias biopolíticas del régimen neoliberal, bajo la dictadura de Pinochet como en años más recientes. Basada en las acciones performativas de una vagabunda – una figura de la marginalidad social –, la novela conlleva una ambivalencia que analizo a través de las categorías de espacio, lenguaje e identidad, subrayando su potencialidad de “perversión” en relación con el orden social y simbólico.

description: Modern wars are not performed now defending the sovereign, but in the name of the group existence, as Foucault sustained. That´s why wars cause many nationalism excesses and  debates through which traditions are updated and reviewed and  the Nation´s values and its member´s life values are weigh up. In this paper some of these debates are analyzed through the particular case of Malvinas War (1982), same as the way they have affected the soldiers which lives were involved, from the reading of testimonial tales.
description: Como sostuvo Foucault, las guerras modernas ya no se realizan en defensa del soberano sino en nombre de la existencia del grupo. Es por eso que provocan tanto exacerbaciones del nacionalismo como debates en los que se actualizan y revisan las tradiciones y se sopesa el valor de la nación con el de la vida del individuo que pertenece a ella. En este trabajo, se analizan algunos de estos debates para el caso particular de la guerra de Malvinas (1982), así como también el modo en que repercutieron en los soldados cuyas vidas estaban en juego, a partir de la lectura de relatos testimoniales.

description: Social exclusion is a negative experience in social interaction which can be modulated by the perceived eye gaze. In our Cyberball study, we asked how gaze direction – direct versus averted – affects the processing of social exclusion by using electroencephalogram (EEG) methods. Participants encountered neutral gazes in the inclusion phase (Block1) and then either direct or averted gazes during the exclusion phase (Block2). We measured self-reports on Need-Threat Questionnaires (belonging, control, meaningful existence, self-esteem) and negative mood, along with event-related potentials (ERPs), specifically the P3 component (P300) - an indicator of expectation violation. Findings demonstrated that the P3 amplitude showed differential changes between gaze conditions during the transition from inclusion to exclusion, with direct gaze eliciting stronger neural responses. This difference signals that direct gaze enhances the expected participation, thus sensitizing participants for exclusionary signals. Simultaneously, self-reports indicated that the transition evoked weaker negative emotions in the direct gaze group and stronger negative emotions in the averted gaze group, signalling that direct gaze also serves as an affiliative signal. These results illuminate how gaze directions shape cognitive and emotional reactions to social exclusion. However, further research is necessary to unravel these effects amidst other non-verbal cues and fully comprehend their impact on neural and behavioural responses to social exclusion.

Long term thermal energy storage

description: Total produced energy in the world is mostly consumed as thermal energy which is used for space or water heating. Currently, more than 85% of total thermal energy consumption is supplied from fossil fuels. This high consumption rate increases the depletion risk of fossil fuels as well as causing a tremendous release of hazardous gases such as carbon dioxide, carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter that effects both environment and human health. Those drawbacks force humankind to search for new technologies, like renewables, to reduce fossil fuel dependency on thermal energy production. Thermal energy storage in adsorbent beds is one of the resulting technologies. Adsorption is an exothermic process in which a fluid (adsorbate) diffuses into the pores of a porous solid material (adsorbent) and trapped into the crystal lattice. In this system, exothermic adsorption of water vapor from air is carried out by using hybrid adsorbent of activated alumina and zeolite. In previous studies, through literature review, this adsorbent was selected to be the most efficient adsorbent for this process due to its high water adsorption capacity, high heat of adsorption, and stability [Dicaire and Tezel, 2011]. In this study, previous studies started on this project was confirmed and pursued by trying to increase the efficiency of the process and confirm the feasibility and applicability of this system in larger scales. In this thesis, various zeolite and activated alumina hybrid adsorbents with varying zeolite compositions were screened to find the most efficient adsorbent for thermal energy storage process that gives the highest energy density. Then, existing small column was replaced with a new one, which is 16 times bigger in volume, in order to confirm the feasibility of this process at larger scales. Applicability of on-off heat release in adsorption process was also investigated by conducting several on-off experiments at different on-off time periods. Moreover, exothermic adsorption process was modeled by doing mass and energy balances in the column, water accumulation balance in the pellets, and energy balance in the column wall. Validity of this model was confirmed by comparing it with experimental results at different column volumes, and at different volumetric flow rates. Finally, an overall plant design, capital cost and thermal energy price estimations were done for adsorption thermal energy storage plants for different storage capacities and payback periods.

description: An illusion concerning the apparent length of a horizontal line was induced by superposition of geometric elements, ie five vertical stripes or a circular line, respectively. These contextual elements were varied in size which is equivalent to a variation of their information density. In several experiments, the perceived length of the line has been found to increase as a function of the information density of the pattern. This is interpreted as due to a size constancy effect, ie the conspicuity range is reduced, to achieve better resolution of closely spaced stripes or a small circular line. This affects the perceived length of the target line, too. From this conceptual model the mathematical functions y(x)=A·x ^- ^n, y(x)=A·x ^n, and y(x)=A·x ^n^·^exp^(-B·x) are derived and fitted to the results of the experiments, with n being the size constancy parameter. Depending on the experimental conditions, values of n= 0.0756(77), n=0.058(12), n=0.0366(94), and n=0.0503(57) are obtained.

Min System

description: The Min system ensures that gram-negative bacteria undergo symmetric cell division. The three Min proteins, MinC, MinD, and MinE, display a dynamic pattern of subcellular organization on the inner cell membrane that directs division proteins to the mid-cell. This process is driven by the ATPase activity of MinD that is stimulated through its interaction s with Min E. A recent structure of MinE in complex with MinD suggests that MinE undergoes a dramatic conformational change to allow MinD - binding residues to be released from the MinE hydrophobic core. However, this structure used a MinE mutant designed to favor this conformational change, raising questions regarding the mechanism by which wild - type MinE can undergo this transition in vivo. One potential scenario that might explain this structural change involves a recently discovered interaction between MinE and the membrane surface. To investigate the possibility that lipid binding could induce this structural transition in MinE, circular dichroism and enzyme kinetics studies were carried out. These studies were also done on MinE mutants designed to either eliminate membrane binding or induce the conformational change involved in MinD - binding. The results demonstrated that a membrane induced conformational change does occur, and requires the presence of a key lipid - binding region at the N - terminus. However, removal of this sequence failed to alter the kinetics of MinE - stimulated MinD - catalyzed ATP hydrolysis. Overall, our results provide a step forward in our understanding of the role of the interaction between MinE and the membrane in the Min system, but also highlight the need for additional investigation before this system might be used as a novel antibiotic target for pathogenic, gram - negative bacteria such as Neisseria gonorrhoeae.

Bipolar disjunction

description: Only thirty known species have populations at high latitudes in both hemispheres, this is, a bipolar distribution. Five of them belong to the genus Carex. Before attempting to elucidate the origins of such distributions, we need to resolve taxonomical problems that are typically encountered in such species. We focus on the Carex capitata complex, which includes Carex arctogena as a bipolar species, in worldwide scope sampling. A morphometric study and phylogenetic analyses based on maximum parsimony, Bayesian inference and Statistical Parsimony have revealed: a) C. capitata and C. arctogena are different species; b) C. anctarctogena is a synonym of C. arctogena and c) a great biodiversity previously undetected in western North America that could lead to the description of three new taxa (“Carex cayouetteana”, Carex sp. nov. 1 and 2) comprised in the so called “C. cayouetteana” lineage. More studies are needed in some C. capitata samples from Russia that appears in the molecular analyses in a strongly supported clade.

This dissertation presents acomprehensive review and background on the development of new organocatalyticpericyclic reactions methods, specifically cycloadditions and sigmatropicrearrangements, leading to asymmetric small molecules. Herein, the research thatwas conducted and lead to two successful new discoveries are described. The topicsspecifically discussed in this dissertation are: 1.) Cycloaddition reactions catalyzedby primary and secondary chiral amine catalysts since 2011. 2.) Sigmatropicrearrangements that have been catalyzed by organocatalysts in general. 3.) A novel[5 + 2] cycloaddition reaction catalyzed by a diphenyl prolinol silyl ether. 4.) AClaisen rearrangement kinetic resolution of g-substituted O-allyl a,b-unsaturatedaldehydes catalyzed by 2,5-diphenyl pyrrolidine. The methodologies reviewed areall groundbreaking achievements improving the scope of pericyclic reactions thatachieve optically active products, that can potentially act as precursors to even largerchiral building blocks as a part of molecular architectures.

description: César Aira’s novel La Villa is not about the life in the shanty town: it tells the way shanty towns are perceived by the other city dwellers. Instead of focusing on the villa miseria, it focuses on the role it plays in the city’s self-representation. The social stereotypes that are commonly associated to the shanty town are ironically assimilated into the narrative perspective, allowing the text to enquire obliquely the social discourses that nourish and  support  its construction as a foreign body inside the city.

description: Data Stream mining is an important emerging topic in the data mining and machine learning domain. In a Data Stream setting, the data arrive continuously and often at a fast pace. Examples include credit cards transaction records, surveillances video streams, network event logs, and telecommunication records. Such types of data bring new challenges to the data mining research community. Specifically, a number of researchers have developed techniques in order to build accurate classification models against such Data Streams. Ensemble Learning, where a number of so-called base classifiers are combined in order to build a model, has shown some promise. However, a number of challenges remain. Often, the class labels of the arriving data are incorrect or missing. Furthermore, Data Stream algorithms may benefit from an online learning paradigm, where a small amount of newly arriving data is used to learn incrementally. To this end, the use of Active Learning, where the user is in the loop, has been proposed as a way to extend Ensemble Learning. Here, the hypothesis is that Active Learning would increase the performance, in terms of accuracy, ensemble size, and the time it takes to build the model. This thesis tests the validity of this hypothesis. Namely, we explore whether augmenting Ensemble Learning with an Active Learning component benefits the Data Stream Learning process. Our analysis indicates that this hypothesis does not necessarily hold for the datasets under consideration. That is, the accuracies of Active Ensemble Learning are not statistically significantly higher than when using normal Ensemble Learning. Rather, Active Learning may even cause an increase in error rate. Further, Active Ensemble Learning actually results in an increase in the time taken to build the model. However, our results indicate that Active Ensemble Learning builds accurate models against much smaller ensemble sizes, when compared to the traditional Ensemble Learning algorithms. Further, the models we build are constructed against small and incrementally growing training sets, which may be very beneficial in a real time Data Stream setting.

description: This thesis examined the antimicrobial activity of select neotropical plants from Costa Rica and traditional Q’eqchi Maya medicines from Belize. In particular the potential for interference with bacterial quorum sensing (QS) and biofilm formation as well as fungal growth were assessed. Of one hundred and twenty six extracts collected from Costa Rica, one third showed significant QS inhibition while 13 species displayed more biofilm inhibitory activities than the positive control allicin. The active species belonged to the Lepidobotryaceae, Melastomataceae, Meliaceae, Sapindaceae, and Simaroubaceae. Twelve Marcgraviaceae species were tested for the same biological activities; of these, three showed similar QS inhibition to that of the positive control Delisea pulchra (Greville) Montagne and five with at least 30% biofilm inhibition. Only one species inhibited fungal growth – Marcgravia nervosa Triana & Planch. Bioassay-guided isolation of this plant resulted in the identification of the active principle as a naphthoquinone, with a minimum inhibitory concentration (MIC) ranging from 85 to 100 μM against Saccharomyces cerevisiae. Similarly, sixty one Q’eqchi’ Maya medicinal plant species were evaluated for their antimicrobial activities. Of these, four species showed more QS inhibition than D. pulchra, seven with comparable biofilm inhibitory activities that of allicin, and two with similarly antifungal activity to berberine. Two spirostanol saponins were isolated from Cestrum schlechtendahlii G.Don, an active antifungal plant. The major saponin showed growth inhibition against Saccharomyces cerevisiae and Fusarium graminearum, with MICs of 16.5 μM and 132 μM, respectively. Further analyses of this compound using chemical genomics suggested that its antifungal mechanism of action is pleiotropic, affecting multiple targets. Taken together, these findings showed that neotropical plants and traditional Q’eqchi’ Maya medicines contain phytochemicals that interfere with bacterial biofilm formation and quorum sensing as well as fungal growth.

description: In this thesis, a novel Pedestrian Protection System (PPS), composed of the Pedestrian Detection System (PDS) and the Pedestrian Tracking System (PTS), was proposed. The PPS is a supplementary application for the Advanced Driver Assistance System, which is used to avoid collisions between vehicles and pedestrians. The Pedestrian Detection System (PDS) is used to detect pedestrians from near to far ranges with the feature-classi er-based detection method (HOG + SVM). To achieve pedestrian detection from near to far ranges, a novel structure was proposed. The structure of our PDS consists of two cameras (called CS and CL separately). The CS is equipped with a short focal length lens to detect pedestrians in near-to-mid range; and, the CL is equipped with a long focal length lens to detect pedestrians in mid-to-far range. To accelerate the processing speed of pedestrian detection, the parallel computing capacity of GPU was utilized in the PDS. The synchronization algorithm is also introduced to synchronize the detection results of CS and CL. Based on the novel pedestrian detection structure, the detection process can reach a distance which is more than 130 meters away without decreasing detection accuracy. The detection range can be extended more than 100 meters without decreasing the processing speed of pedestrian detection. Afterwards, an algorithm to eliminate duplicate detection results is proposed to improve the detection accuracy. The Pedestrian Tracking System (PTS) is applied following the Pedestrian Detection System. The PTS is used to track the movement trajectory of pedestrians and to predict the future motion and movement direction. A C + + class (called pedestrianTracking class, which is short for PTC) was generated to operate the tracking process for every detected pedestrian. The Kalman lter is the main algorithm inside the PTC. During the operation of PPS, the nal detection results of each frame from PDS will be transmitted to the PTS to enable the tracking process. The new detection results will be used to update the existing tracking results in the PTS. Moreover, if there is a newly detected pedestrian, a new process will be generated to track the pedestrian in the PTS. Based on the tracking results in PTS, the movement trajectory of pedestrians can be obtained and their future motion and movement direction can be predicted. Two kinds of alerts are generated based on the predictions: warning alert and dangerous alert. These two alerts represent di erent situations; and, they will alert drivers to the upcoming situations. Based on the predictions and alerts, the collisions can be prevented e ectively. The safety of pedestrians can be guaranteed.

description: Purpose: Elite rowers have large body dimensions, a high metabolic capacity, and they realize high training loads. These factors suggest a high total energy requirement (TER), due to high exercise energy expenditure (EEE) and additional energetic needs. We aimed to study EEE and intensity related substrate utilization (SU) of elite rowers during rowing (EEEROW) and other (EEENON-ROW) training. Methods: We obtained indirect calorimetry data during incremental (N = 174) and ramp test (N = 42) ergometer rowing in 14 elite open-class male rowers (body mass 91.8 kg, 95% CI [87.7, 95.9]). Then we calculated EEEROW and SU within a three-intensity-zone model. To estimate EEENON-ROW, appropriate estimates of metabolic equivalents of task were applied. Based on these data, EEE, SU, and TER were approximated for prototypical high-volume, high-intensity, and tapering training weeks. Data are arithmetic mean and 95% confidence interval (95% CI). Results: EEEROW for zone 1 to 3 ranged from 15.6 kcal·min−1, 95% CI [14.8, 16.3] to 49.8 kcal·min−1, 95% CI [48.1, 51.6], with carbohydrate utilization contributing from 46.4%, 95% CI [42.0, 50.8] to 100.0%, 95% CI [100.0, 100.0]. During a high-volume, a high-intensity, or a taper week, TER was estimated to 6,775 kcal·day−1, 95% CI [6,651, 6,898], 5,772 kcal·day−1, 95% CI [5,644, 5,900], or 4,626 kcal∙day−1, 95% CI [4,481, 4,771], respectively. Conclusion: EEE in elite open-class male rowers is remarkably high already during zone 1 training and carbohydrates are dominantly utilized, indicating relatively high metabolic stress even during low intensity rowing training. In high-volume training weeks, TER is presumably at the upper end of the sustainable total energy expenditure. Periodized nutrition seems warranted for rowers to avoid low energy availability, which might negatively impact performance, training, and health.

description: N-heterocyclic carbenes (NHCs), commonly derived from N,N’-disubstituted imidazolium salts, have gained popularity since their isolation by Arduengo in 1991 and their application as ligands for catalysis by Herrmann in the mid-1990s. An underexplored area of research is the examination of chelating ligands incorporating amine-functionalized bis(NHC) ligands. This thesis focuses on the synthesis of novel bis(imidazolium) borate salts and the preliminary formation of their NHCs. Early attempts of reacting imidazoles with chlorobis(amino)borane reagents yielded incomplete reactions or decomposition, which are likely the consequence of a steric and/or electronic mismatch between boron and its attached amines. After testing several chloroaminoborane reagents, two novel amine-functionalized bis(imidazolium)borate salts have been successfully synthesized and characterized. By reacting 1-tert-butylimidazole (tBuIm) or 1-methylimidazole (MeIm) with iPr2N(Ph)BCl at room temperature, the salts [iPr2NB(Ph)(tBuIm)2][OTf] and [iPr2NB(Ph)(MeIm)2][OTf] (OTf = trifluroomethanesulfonate) can be prepared using a two-step, one-pot synthetic protocol. Halide abstraction using AgOTf to form the proposed intermediate iPr2NB(Ph)OTf, followed by imidazole addition readily produces the target imidazolium borate salts. Optimization efforts resulted in the discovery of a solvent-dependent mechanism in CH3CN versus CH2Cl2 during addition of AgOTf to iPr2NB(Ph)Cl. In both solvents, the desired product is obtained, however the coordinating effects of CH3CN may play a role in minimizing undesirable product formation. Overall, a reliable synthetic method to obtain amine-functionalized bis(imidazolium)borate salts is presented. Preliminary data suggests that deprotonation leads to carbene formation, however more experiments are needed to fully characterize the product. This work holds promise to prepare novel bis(carbene)aminoborates as proton-responsive ligands for electrocatalytic H2 oxidation/production.

description: The growing accessibility of quantum mechanics and chaos theory over the past eighty years has opened a new mode of world-creating for dramatists. An increasingly large collection of plays organize their fictional worlds around such scientific concepts as quantum uncertainty and chaotic determinism. This trend is especially noticeable within dramatic texts that emphasize a fictional, not material or metafictional, engagement. These plays construct fictional worlds that reflect the increasingly strange actual world. The dominant theoretical approaches to fictional worlds unfairly treat these plays as primarily metafictional texts, when these texts construct fictional experiences to speculate about everyday ramifications of living in a post-quantum mechanics world. This thesis argues that these texts are best understood as examples of speculative fiction drama, and they speculate about the changes to our understanding of reality implied by contemporary scientific discoveries. Looking at three plays as exemplary case studies—John Mighton’s Possible Worlds (1990), Tom Stoppard’s Arcadia (1993), and Tony Kushner’s Homebody/Kabul (2001)—this thesis demonstrates that speculative fiction theories can be adapted into fictional worlds analysis, allowing us to analyze these plays as fiction-making texts that offer nonclassical aesthetic experiences. In doing so, this thesis contributes to speculative fiction studies, fictional worlds studies, and the dynamic interdisciplinary dialogue between aesthetic and scientific discourses.

description: Background: Preeclampsia (PE) is a major cause of short and long-term morbidity for affected infants, including consequences of fetal growth restriction and iatrogenic prematurity. In Brazil, this is a special problem as PE accounts for 18% of preterm births (PTB). In the PREPARE (Prematurity REduction by Pre-eclampsia cARE) study, we will test a novel system of integrated care based on risk stratification and knowledge transfer, to safely reduce PTB. Methods: This is a stepped wedge cluster randomised trial that will include women with suspected or confirmed PE between 20 + 0 and 36 + 6 gestational weeks. All pregnant women presenting with these findings at seven tertiary centres in geographically dispersed sites, throughout Brazil, will be considered eligible and evaluated in terms of risk stratification at admission. At randomly allocated time points, sites will transition to risk stratification performed according to sFlt-1/PlGF (Roche Diagnostics) measurement and fullPIERS score with both results will be revealed to care providers. The healthcare providers of women stratified as low risk for adverse outcomes (sFlt-1/PlGF ≤38 AND fullPIERS< 10% risk) will receive the recommendation to defer delivery. sFlt-1/PlGF will be repeated once and fullPIERS score twice a week. Rates of prematurity due to preeclampsia before and after the intervention will be compared. Additionally, providers will receive an active program of knowledge transfer about WHO recommendations for preeclampsia, including recommendations regarding antenatal corticosteroids for foetal benefits, antihypertensive therapy and magnesium sulphate for seizure prophylaxis. This study will have 90% power to detect a reduction in PTB associated with PE from a population estimate of 1.5 to 1.0%, representing a 33% risk reduction, and 80% power to detect a reduction from 2.0 to 1.5% (25% risk reduction). The necessary number of patients recruited to achieve these results is 750. Adverse events, serious adverse events, both anticipated and unanticipated will be recorded. Discussion: The PREPARE intervention expects to reduce PTB and improve care of women with PE without significant adverse side effects. If successful, this novel pathway of care is designed for rapid translation to healthcare throughout Brazil and may be transferrable to other low and middle income countries.

description: As a cultural and ideological artifact, literature is an important vehicle for the “reframing” of memories. Published in the Spain during the transition, Manuel Vázquez Montalbán’s novel Los mares del Sur (1979) is a politics of memory that not only aims to fictionally represent some accounts of recent historical events, but also shows the ontological specificity of remembering in the context of official amnesia. In doing so the book allows us to see interesting reflections on the importance of the urban changes as “stabilizers” of memories, the tension between memory as a “reconstruction” or as an “irruption” of the past, and on the links between individual memory and social memory.
description: Como artefacto cultural e ideológico, la literatura es un importante vehículo para el “encuadramiento” de memorias. Publicada en la España de la transición, la novela Los mares del Sur (1979) de Manuel Vázquez Montalbán plasma una política de memoria que busca representar ficcionalmente cierta versión de los hechos del pasado reciente de ese país y, a la vez, evidencia el modo en que los actos de rememoración tienen lugar pese a las políticas oficiales de amnesia. Dando cuenta de este fenómeno, la novela promueve interesantes reflexiones sobre la importancia de los cambios urbanísticos como “soporte” de la memoria, sobre la tensión entre una memoria comprendida como “reconstrucción” o como “irrupción” del pasado y sobre los lazos entre memoria individual y memoria grupal.

description: Seven cosmological hydrodynamic simulations of disk galaxy formation are analyzed to determine the alignment of the disk within the dark matter halo and the internal structure of the halo. We find that the orientation of the outer halo, beyond 0.1rvir, is unaffected by the presence of the disk. In contrast, the inner halo is aligned such that the halo minor axis aligns with the disk axis. The relative orientations of these two regions of the halo are uncorrelated. The alignment of the disk and inner halo appears to take place simultaneously through their joint evolution. The lack of connection between these two regions of the halo should be taken into account when modeling tidal streams in the halos of disk galaxies and when calculating intrinsic alignments of disk galaxies based on the properties of dark matter halos.
