Criminalidad común en períodos de revolución: Los discursos del poder en torno a la criminalidad en Pinar del Río, Cuba (1952-1958)
Authors: León Iglesias Juana Marta 
Published: October 2014

Las estrategias que la escuela y la prensa articulan en torno a la criminalidad común son, como el propio fenómeno criminal, temáticas que la historiografía regional pinareña no ha abordado hasta el momento. Sin embargo, el crimen común y las vías con que se afronta por las instancias de control social, tienden lazos inevitables con diversos aspectos de la vida social. Esta aseveración alcanza significación en el contexto del período 1952-1958, en medio del auge de la insurgencia contra el gobierno de facto de Fulgencio Batista. Este texto propone un análisis de cómo los grupos hegemónicos establecieron una serie de discursos que, tomando como base conceptos como la moralidad, el progreso social y la conciliación nacional, criminalizaron a determinados grupos, individuos y comportamientos, con el fin de incrementar el miedo al delito y la inseguridad como mecanismo para justificar hasta donde era posible, la represión policial y judicial.

Common Crime in Revolution Period: Government Ideology about Crime in Pinar del Rio, Cuba (1952-1958)AbstractThe strategies that school and press gears for common crime are, like the essence of the criminal phenomenon, one of the topics that Pinar del Rio regional historiography has not dealt with this far. However, common crime and the ways it has been confronted by social control, create inevitable bonds with all the aspects of social life. This sentence acquires meaning during the 1952-1958 periods, in the heat of the battles against Fulgencio Batista dictatorship. This text seeks to analyse how hegemonic groups established an ideology that, from media practices and taking as a base ideas such as morality, social progress and national agreement, criminalized some determined groups, individual, and behaviour, with the purpose to increase fear to crime and insecurity as a mechanism to justify, as much as possible, police and government repression.Keywords: local press, crime, ideology, local history, Cuba.
Aproximaciones a la historia empresarial de Boyacá (Colombia), 1900-1930
Authors: Acuña Rodríguez Olga Yanet 
Published: October 2014

Este artículo de investigación se ocupa del estudio de la consolidación de empresas en el departamento de Boyacá, entre 1900 y 1930, el capital, la duración y el tipo de actores sociales vinculados, lo que a su vez nos aproxima al proyecto económico que se pretendió implementar en esta región colombiana. El trabajo se adscribe en la historia regional que da cuenta de las dinámicas propias que se generaron en cada región, para lo cual se partió de la revisión historiográfica sobre historia empresarial e historia regional que permitió comprender procesos de desarrollo particulares; posteriormente se realizó la revisión de los protocolos notariales, Notarías primera y segunda de Tunja 1900 – 1930, bajo la perspectiva de establecer el tipo de empresa, la coyuntura de consolidación y la incidencia en el ‘desarrollo’ del departamento. En el Departamento de Boyacá se conformaron sociedades y compañías anónimas para comercializar productos, para la producción manufacturera, desarrollo de actividades financieras, pavimentación de vías y mejoramiento de la producción agrícola, así, tanto mercaderes como casas mercantiles fueron los generadores de recursos que pretendieron comercializar productos nacionales e internacionales, y posiblemente generar cambios en la producción y en el consumo de la región. Approaches to History Business of Boyacá (Colombia), 1900-1930 AbstractThis research paper deals with the study of the consolidation of companies in the department of Boyacá, between 1900 and 1930, capital, duration and the type of social actors involved, which in turn approaches us closer to the economic project that was aimed to be implemented in this Colombian region. The work is ascribed in the regional history that gives account of its own dynamics that was generated in every region, for which the researcher took as point of departure a historiographical review of the business history and regional history for understanding processes of particular development; later on the review was conducted of notarial protocols , First and Second Tunja Notaries 1900 - 1930, under the perspective of establishing the type of company, the climate of consolidation and the impact on the “development” of the department. In the Departamento de Boyacá (department of Boyacá) societies and anonymous companies were formed to market products, for manufacturing, development of financial activities, road paving and improvement of agricultural production, thus, both merchants and merchant houses were the generators of resources that intended to market national and international products, and hopefully lead to changes in the production and consumption of the region products.Keywords: Business history, region, business, company, businessman, Boyacá

ABSTRACTWe analyze photoluminescence (PL) and electroluminescence (EL) using a hyperspectral imager that records spectrally resolved luminescence images of solar cell absorbers. The system is calibrated to yield the luminescence flux in absolute values. This system enables to quantitatively image physical parameters such as the photovoltage with an uncertainty of less than 30mV. The wide field illumination, low power excitation and fast acquisition brings new insights compare to classical setups such as confocal microscope. Several types of absorbers have been analyzed. For instance, we can investigate spatial fluctuations of the Quasi Fermi Levels splitting in CIGS polycristalline absorbers and link those fluctuations to transport properties. The method is general to the point that third generation PV cells absorbers can also be evaluated. We illustrate the great potential of our setup by imaging quasi Fermi levels splitting in Intermediate Band Solar cells. Such techniques, directly evaluating the performance of photovoltaic absorbers and devices are needed for fast, high throughput investigations of combinatorial experiments such as the projects carried out for the material genomics programme.

ABSTRACTA cross-linked copolymer was designed and synthesized bythe imidation of poly(oxyethylene)-diamine and 4,4’-oxydiphthalic anhydride, and followed by a late-stage curing to generate the cross-linked gels. The copolymers consisting of crosslinking sites and multiple functionalities such aspoly(oxyethylene)-segments, amido-acids, imides, and amine termini, characterized by Fourier Transform Infrared Spectroscopy. After the self-curing at 80 °C, the gel-like material enabled to absorb liquid form of electrolytesin the medium of propylene carbonate(PC), dimethylformamide(DMF),and N-methyl-2-pyrrolidone(NMP).By using a field emission scanning electronic microscope, we observed a 3D interconnected nanochannel microstructure, within which, the liquid electrolytes were absorbed. When the novel polymer gel electrolyte (PGE) was fabricated into a dye-sensitized solar cell (DSSC), an extremely high photovoltaic performance was demonstrated. The PGE, absorbed 76.7 wt% of the liquid electrolyte (soaking in the PC solution) based on the polymer’s weight gave rise to a power conversion efficiency of 8.31%, superior to that (7.89%) of the DSSC with liquid electrolytes. It was further demonstrated that the cell had a long-term stabilityduring the test of 1000hat-rest at room temperature or only slightly decreasing in efficiency of 5%.This is the first time demonstration for a PGE exhibiting a higher performance than its liquid counterpart cell. The observation is ascribed to the suppression of the back electron transfer through the unique morphology of the polymer microstructures.

Abstract
The development, life history, and fecundity of Acharia fusca Stoll (Lepidoptera: Limacodidae), an important oil palm pest, was studied at various treatments of temperatures ranging from 10 to 40°C, at a constant relative humidity of 75 ± 5% and a photoperiod of 12:12 (L:D) h. In addition, the amount of leaf consumed by larval instars was measured. Females and males successfully developed into adults within 15–35°C. However, no eggs were found at 10°C, and all adults died after exposure to 40°C. The developmental time from egg to adult ranged between 170.5 d at 15°Cand 76.6 d at 35°C (F1,97 = 56.2; P &lt; 0.0001). Temperature had a strong effect on the survivorship of A. fusca from the egg to adult emergence, increasing between 15 and 20°C, peaked at 25–30°C, and then declined slightly at 35°C. The different periods of the insect's total reproductive life varied between 15 and 35°C, with the preoviposition periods ranging between 6.82 and 3.24 d, the oviposition period between 17.5 and 4.89 d, and the postoviposition period between 5.29 and 0.82 d. Female longevity was greater than male longevity at all temperatures. The total amount of leaf area consumed by one larva was 402.31 cm2. The results indicated that the development period from egg to adult death at the decreased with increasing temperature and the larvae maintained a high consumption rate on Elaeis guineensis Jacquin leaves. The effect of temperature on development, survival, and reproduction of A. fusca can be useful for predicting its long-term population fluctuation as an invasive pest of oil palm plantations.

Objectives. We investigated the role of socioeconomic factors in Black–White disparities in preterm birth (PTB). Methods. We used the population-based California Maternal and Infant Health Assessment survey and birth certificate data on 10 400 US-born Black and White California residents who gave birth during 2003 to 2010 to examine rates and relative likelihoods of PTB among Black versus White women, with adjustment for multiple socioeconomic factors and covariables. Results. Greater socioeconomic advantage was generally associated with lower PTB rates among White but not Black women. There were no significant Black–White disparities within the most socioeconomically disadvantaged subgroups; Black–White disparities were seen only within more advantaged subgroups. Conclusions. Socioeconomic factors play an important but complex role in PTB disparities. The absence of Black–White disparities in PTB within certain socioeconomic subgroups, alongside substantial disparities within others, suggests that social factors moderate the disparity. Further research should explore social factors suggested by the literature—including life course socioeconomic experiences and racism-related stress, and the biological pathways through which they operate—as potential contributors to PTB among Black and White women with different levels of social advantage.

Objectives. We investigated relations between changes in neighborhood ethnic composition and changes in body mass index (BMI) and waist circumference among Chinese and Hispanic immigrants in the United States. Methods. We used Multi-Ethnic Study of Atherosclerosis data over a median 9-year follow-up (2000–2002 to 2010–2012) among Chinese (n = 642) and Hispanic (n = 784) immigrants aged 45 to 84 years at baseline. We incorporated information about residential moves and used econometric fixed-effects models to control for confounding by time-invariant characteristics. We characterized neighborhood racial/ethnic composition with census tract–level percentage Asian for Chinese participants and percentage Hispanic for Hispanic participants (neighborhood coethnic concentration). Results. In covariate-adjusted longitudinal fixed-effects models, results suggested associations between decreasing neighborhood coethnic concentration and increasing weight, although results were imprecise: within-person BMI increases associated with an interquartile range decrease in coethnic concentration were 0.15 kilograms per meters squared (95% confidence interval [CI] = 0.00, 0.30) among Chinese and 0.17 kilograms per meters squared (95% CI = –0.17, 0.51) among Hispanic participants. Results did not differ between those who did and did not move during follow-up. Conclusions. Residential neighborhoods may help shape chronic disease risk among immigrants.
Nonmedical Exemptions From School Immunization Requirements: A Systematic Review
Authors: Wang Eileen , Clymer Jessica , Davis-Hayes Cecilia , Buttenheim Alison 
Published: October 2014

We summarized studies describing the prevalence of, trends in, and correlates of nonmedical exemptions from school vaccination mandates and the association of these policies with the incidence of vaccine-preventable disease. We searched 4 electronic databases for empirical studies published from 1997 to 2013 to capture exemption dynamics and qualitatively abstracted and synthesized the results. Findings from 42 studies suggest that exemption rates are increasing and occur in clusters; most exemptors questioned vaccine safety, although some exempted out of convenience. Easier state-level exemption procedures increase exemption rates and both individual and community disease risk. State laws influence exemption rates, but policy implementation, exemptors’ vaccination status, and underlying mechanisms of geographical clustering need to be examined further to tailor specific interventions.
Floating LNG Chain - Finally a Reality
Authors: Choi Michael S. 
Published: October 2014

Abstract
It was more than a decade ago that the visionaries of Project Azure predicted that possibly by 2004, a complete floating LNG chain could be built including floating FPSO (FLNG) and a floating LNG FSRU (Floating Storage, Regasification Unit), linked by LNG shuttle tankers transporting LNG from the FLNG to the FSRU. Today in 2014, the chain still does not exist. Although there are many floating LNG receiving terminals operating successfully around the world, the elusive FLNG has still not materialized. However, now that construction has started on Shell’s Prelude and Petronas’s PFLNG-1, realization of the vision of floating LNG chain is imminent.
Many technology advancements have combined to make floating LNG chain a reality. Maturation of subsea well and control systems have mitigated the risks of subsea well operations. Proven glycol (MEG) and other regenerative hydrate management systems have allowed longer tie-back distance. Cost-effective mooring systems for large FPSO, flexible flow-lines and catenary risers have enabled floating system of FLNG size to be seriously considered. However, it is the advance of floating LNG technologies that have evolved over the past 20 years that finally tipped the risk-reward equation. Technologies such as offshore ship-to-ship LNG transfer, motion tolerant processing and rotating equipment, LNG spill and gas safety, and deep water cooling water lift systems have matured to an acceptable level.
The rewards of FLNG are very compelling. Major cost savings can be achieved by eliminating: Well head/production platform(s)Processing platform to facilitate gas treating, liquids recovery and stabilizationFSO for condensate and NGL productsGas compressor and pipeline to transport gas to an onshore LNG plant
and replace with a FLNG system located in the field. There are also the intangible cost savings such as efficiency gains by constructing the entire system in a ship yard, material and manpower logistics, and shorter project duration. In places where space constraint and regulatory restrictions make land-based LNG liquefaction and regasification difficult, FLNG and FSRU are cost-effective alternatives.
This paper will present the economics drivers that make floating LNG chain attractive to producers and buyers alike, and the many conventional production technologies and those unique to FLNG that combined to enable FLNG chain to be developed with confidence. The realization of floating LNG chain will enhance the economics of LNG as a preferred fuel.
A Sector Model for IOR/EOR Process Evaluation
Authors: Wang Shie-Way , Yeskaiyr Batima , Walker Chuck 
Published: October 2014

Abstract
The Tengiz field is a giant naturally fractured carbonate reservoir with 44° API oil and 12% H2S content. This work presents a methodology to construct a sector model for the Tengiz field which is used to evaluate IOR/EOR processes to increase oil recovery through the life of the field. Current development plans call for expansion of sour gas injection in the platform area of Tengiz. Additional long term focus is now directed towards the fractured slope region of the field. IOR/EOR is a natural alternative to supplement reservoir energy, improve recovery efficiency, and convert resources to reserves, then to production.
Reservoir simulation requires using a dual porosity dual permeability model and equation of state to model PVT properties. Unlike most published sector models which are usually limited to a section of 5-spot pattern, this sector model covers 1/6 of the field area and is complicated by natural fractures, plant capacity limitations, complex production rules, existing sour gas injection, and high well count. This work presents a method to treat plant capacity limitations, boundary flux, edge wells, and compositional effects to replicate full field model performance and subsequently to generate alternative predictions.
This model matches production/injection data of existing wells and the anticipated performance of future wells in the full field model. Matching parameters include oil production rate, GOR, flowing bottom-hole-pressure (BHP), saturation profile, and reservoir pressure profile at the field and well level. The BHP at all future development well locations are also matched.
The sector model was also used to determine optimal well count of infill producer. The methodology to do so is discussed in this work as well. The on-going work and forward plan focus on evaluating the concentration profile of all injectants, impact of injection rate, gas production management, new development well locations, and interference among all wells. The success of sector model enables Tengizchevroil to run numerous IOR scenarios in a much shorter time frame so that only those prioritized runs can be evaluated on a full-field basis.
Improving the Decision Making Process between Drilling and Completion Using Real-Time Torque and Drag Modeling
Authors: Brown Casey , McCormick John , Nunez Ana 
Published: October 2014

Abstract
Real-time Torque and Drag (RTD) Modeling can improve the decision-making process at the rig site, resulting in greater economical returns, time saved, and many more benefits. Described in this paper is a revolutionary RTD modeling procedure that can use completion requirements and real-time drilling data to optimize wellbore construction decisions made while drilling and conditioning. Though this advanced method has many different uses, this technical paper will discuss changing the workstring within a deviated or complex wellbore that gives rise to large amounts of torque and drag. Primarily applied to the wellbore construction phase, RTD is designed to improve bottom line results. This paper will provide a field application and describe the process associated with successfully performing RTD modeling.
