Published: March 2018

Introducción: La relación causa efecto entre la hipertensión arterial sistémica y un mayor riesgo para desarrollar síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) es aún incierta. El desconocimiento de la influencia del SAHOS sobre lahipertensión arterial ha llevado al excesivo diagnóstico de hipertensión arterial idiopática, desmotivando la búsqueda de la real causa subyacente, que en la mayoría de los casos puede deberse a trastornos del sueño. Materiales y métodos: En el presente estudio se incluyen pacientes hipertensos quienesconsultaron en el centro médico ONIRIS, especializado en sueño, y se evaluó en ellos variables como índice de masa corporal, índice cintura cadera, circunferencia del cuello, tabaquismo y alcohol, para determinar cuáles de ellos desarrollaron SAHOS.Resultados: De 309 pacientes estudiados, el 67,4%, fue positivo para SAHOS, confirmando algún grado de asociación entre ésta y la hipertensión arterial. Además, variables incluidas como factores de riesgo arrojaron resultados muy similares a losobtenidos en otros estudios que han demostrado dicha asociación. Conclusiones: Tiene predominio por el sexo masculino, se presenta generalmente en mayores de 50 años y obesos; dichos factores ponen en un riesgo elevado al pacientede desarrollar eventos vasculares que disminuyen la calidad de vida e incluso llevarlo a la muerte.

Published: March 2018

In this study have
been investigated the effects of heavy metals on foraminiferal assemblages in
Çanakkale Strait. For this purpose, core samples were collected from 12
locations in the Çanakkale Strait. With the consideration of the faunal and
sedimentological properties of the samples have been showed that the Çanakkale
Strait is completely has rich marine foraminifer populations. The abnormalities
observed of foraminifer the yellow and/or black colored shells have been due to
natural and anthropogenic ecological pollution. In the present study the
pollution index (PI) values were calculated to bring to light the heavy metal
pollution.

Especially in the
ports, Morphological abnormalities and the color changes have been seen at
shales of benthic foraminifer genera and species. Morphological changes were
observed in Elphidium crispum, Massilina secans, and Ammonia compacta
foraminifer species in the core samples taken in areas where ports in the Çanakkale Strait. Especially
Morphological changes were observed in Elphidium crispum, Massilina secans, and
Ammonia compacta foraminifer species in the core samples taken in areas
where ports in the Çanakkale Strait. The
pollution index (PI) value measured in Ports have been higher than the critical
value, indicating that heavy metal concentrations affect the foraminifera.

Authors: Tavares Jousilene de Sales , Melo Adriana , Maciel Bruno , Vasconcelos Amanda , Alves Joao Guilherme , Amorim Melania 
Published: March 2018

Background/Aim: Maternal hemodynamic responses (heart rate, systolic and diastolic blood pressure) were compared during two types of moderate-intensity physical exercise.
Methods: A randomized clinical trial compared 120 pregnant women performing physical exercise on a treadmill (n=64) or stationary bicycle (n=56). In 44 of these women (n=23 treadmill; n=21 bicycle), blood pressure was monitored for 24 hours following exercise. Repeated-measures analysis compared maternal heart rate, systolic and diastolic blood pressure before, during and in the 24 hours following exercise in both groups.
Results: Maternal heart rate increased significantly (p<0.001) with both types of exercise (from 84 at rest to 112 bpm on the treadmill and from 87 at rest to 107 bpm on the bicycle), without exceeding the limit of 140 bpm. Systolic pressure increased from 110 at rest to 118 mmHg on the bicycle (p=0.06) and from 112 at rest to 120 mmHg on the treadmill (p=0.02). Systolic pressure dropped steadily following exercise, reaching its lowest level (104 mmHg) after 14 hours, increasing thereafter and returning to pre-exercise levels by the 19th hour. Diastolic pressure increased during exercise irrespective of the type of exercise (p=0.27), from 70 at rest to 75 mmHg on the bicycle (p=0.39) and from 70 at rest to 76 mmHg on the treadmill (p=0.18), with the lowest level (59 mmHg) being at the 13th hour.
Conclusions: A slight increase in blood pressure levels was found during exercise; however, this was not clinically significant and was followed by a substantial hypotensive effect that lasted around 19 hours.

Multiple Paths of Deuterium Fractionation in Protoplanetary Disks
Authors: Aikawa Yuri , Furuya Kenji , Hincelin Ugo , Herbst Eric 
Published: March 2018

Abstract
We investigate deuterium chemistry coupled with the nuclear spin-state chemistry of H2 and

in protoplanetary disks. Multiple paths of deuterium fractionation are found; exchange reactions with D atoms, such as HCO+ + D, are effective in addition to those with HD. In a disk model with grain sizes appropriate for dark clouds, the freeze-out of molecules is severe in the outer midplane, while the disk surface is shielded from UV radiation. Gaseous molecules, including DCO+, thus become abundant at the disk surface, which tends to make their column density distribution relatively flat. If the dust grains have grown to millimeter size, the freeze-out rate of neutral species is reduced and the abundances of gaseous molecules, including DCO+ and N2D+, are enhanced in the cold midplane. Turbulent diffusion transports D atoms and radicals at the disk surface to the midplane, and stable ice species in the midplane to the disk surface. The effects of turbulence on chemistry are thus multifold; while DCO+ and N2D+ abundances increase or decrease depending on the regions, HCN and DCN in the gas and ice are greatly reduced at the innermost radii, compared to the model without turbulence. When cosmic rays penetrate the disk, the ortho-to-para ratio (OPR) of H2 is found to be thermal in the disk, except in the cold (≲10 K) midplane. We also analyze the OPR of

and H2D+, as well as the main reactions of H2D+, DCO+, and N2D+, in order to analytically derive their abundances in the cold midplane.

Published: March 2018

AbstractThe life cycle of the avian parasitic fliesPhilornisMeinert (Diptera: Muscidae) is poorly known, limiting the understanding of the ecology of these flies, including interactions with their hosts. We provide data on length and survival of pupal and adult stages and the duration of the pre-oviposition period ofPhilornis torquansNielsen. Specimens were collected at larval and pupal stages from infested broods. The pupal stage lasted on average 10.5 days and adults lived up to 100 days in the laboratory. At least 90.2% of larvae pupated and 85.7% of the latter emerged as adults. For individuals collected as larvae, pupal mortality was 3.5 times higher than for those collected as pupae. Females laid from 1–8 clutches in their lifetime and deposited, on average, 41 eggs per female (range: 1–148). Females collected as pupae were larger and had shorter pre-oviposition periods and lifespans than females collected as larvae, but there were no differences in the total eggs laid by these females. This is the first information on reproductive parameters of a subcutaneous species ofPhilornis, and forms the basis for studies on conditions required for reproduction of this species in captivity.
An Innovative Solution for Preventing Gas Migration through Cement Slurry in the Lower Indus Basin of Pakistan

Published: March 2018

AbstractThe integrity of well construction plays an important role to recover the hydrocarbons from subsurface to surface safely and economically. The poor cement integrity behind the casing becomes the cause of gas migration and ultimate well abandonment. The lower Indus basin of Pakistan has the majority of gas producing wells and some of them are plugged due to poor cementing. This is caused by the substantial decrease in the performance of cement slurry with increase in temperature as a function of depth.Therefore, it is essential to improve the API properties of cement slurry at high temperature for minimizing fluid loss and preventing the gas migration. For this purpose, different types of polymer have widely been used as the additives in cement slurry, but those polymers show thermal thinning behavior above 158 °F temperature. Polymers have also been modified by adding chemicals to improve their thermal stability range. However, the addition of chemicals affects the properties of other additives and increases the cost of cementing operation.This paper presents the incorporation of Hydroxypropylmethylcellulose (HPMC) cellulose type polymer in cement slurry which acts as a thickener, film foamer and water retention agent. It is capable of increasing the viscosity at elevated temperature. The viscosity of HPMC solutions was determined experimentally at different temperatures ranging from 86 °F to 212 °F with respect to shear rates. The HPMC polymer showed remarkable rheological properties as a thermal thickener at 194 °F. HPMC solution was then combined with cement slurry to evaluate its API properties such as rheology, fluid loss, free water settling, thickening time and transition time at 194 °F. The experimental results showed that HPMC based cement slurries have significant rheology, minimal fluid loss, zero free water, extended thickening time. The transition time of slurries was less than 45 minutes which is considered as the excellent cement slurry for preventing gas migration as per API standards.It is concluded that HPMC based cement slurries performed as the multifunctional additive, which successfully improved the properties of slurry and prevented the gas migration at high temperature. Hence, field application of HPMC polymer will be a prominent and a cost effective technique for the petroleum industry during cementing operation in the lower Indus basin, Pakistan.

Published: March 2018

Abstract
Floating Offshore Wind Turbines (FOWT), Current and Tidal Turbines (CTT), Wave Energy Converters (WEC) and Ocean Thermal Energy Converters (OTEC) are promising Marine Renewable Energy (MRE) technologies. Considering the emerging stage of development of MRE technologies, no dedicated certification scheme has been developed so far by international organizations. Technical specifications are under development in the framework of the International Electrotechnical Commission (IEC) Technical Committee (TC) 114 and IEC Renewable Energy (IECRE) has been recently created. Within IECRE, the Marine Energy Operational Management Committee (ME OMC) is in charge of the development of a conformity assessment system dedicated to MRE.
In this context, Bureau Veritas (BV) has issued a Guidance Note NI631 Certification Scheme for Marine Renewable Energy Technologies to support technology developers and speed up commercial phases. The note NI631 covers different types of technology for energy conversion from wind, wave, tidal or temperature gradients at sea.
This paper presents the Guidance Note NI631, which purpose is to provide an overview of the certification schemes applicable to MRE technologies, addressing prototype, component, type and project certification. Main objective, scope, intermediary steps to be completed and resulting certificates will be detailed for each certification scheme, as well as their interactions.
Finally, focus will be made on a riskbased approach developed by Bureau Veritas to define the reference set of standards used as a basis for certification. A methodology relying on the qualification of new technology process will be detailed when no guidelines or standards are available for the most innovative parts of any MECs, or when existing standards from related sectors, such as wind energy, shipping or offshore Oil&Gas, require adaptations to fit their requirements to the specific MRE conditions.
Mobile Water Injection Facilities: Case Study of Brownfield Redevelopment Strategy

Published: March 2018

Abstract
Brownfield redevelopment presents challenges such as project risks, uncertain rate of return and cost optimization. A Malaysian offshore brownfield, which has been producing for more than 30 years, is redeveloped through infill drilling of new oil producer wells and water injector wells. Water injection facilities are brought into this brownfield by an MOPU. In this case study, a previous drilling rig was refurbished and converted into a mobile water injection facilities jack-up. Total duration of 12 months was taken to complete the conversion, mobilize, install, tie-in to the brownfield facilities, and commission the unit. The mobile and leased application of this water injection facilities jack-up mitigates the project risks, addresses the uncertain returns, reduces the initial capital investment, and has the flexibility to be relocated. It also contributes to the overall brownfield operations, by upgrading its philosophy from unmanned to manned concept.
