Film Cooling Experimental Study on Sinusoidal Corrugated Liner for Afterburner
Authors: Yong Shan , Xiao Ming Tan , Jing Zhou Zhang , Yan Hua Wu 
Published: July 2017

Abstract
The need of improved cooling effectiveness for hot components in jet engines has led to new designs of afterburner liners. In the present paper, experiments were performed to reveal the cooling characteristics and flow loss of various sinusoidal corrugated liners for an advanced afterburner. It is found that there are alternate high temperature and low temperature zones corresponding to the wave crests and troughs of the corrugated liner, respectively. Compared to the flat liner, the corrugated liner increases cooling effectiveness by 10 % at the blowing ratio of 0.5, by 4.5 % at the blowing ratio of 3.2. However, the difference in discharge coefficients for these two kinds of liners is only 4.3 %. The increased opening ratio of film holes from 1.42 % to 3.72 % for corrugated liners is able to improve the cooling effectiveness by 9.8 %. However, the discharge coefficient is decreased by 34.1 %. The augment of amplitude of liners can enhance the ram effect of cooling air, which has an advantage to increase the local blowing ratio, and to form good cooling film at the windward of wave troughs. The flow loss is bigger while the cooling effectiveness is enhanced due to the change of amplitude of the liner.
Severe diabetic ketoacidosis complicated by hypocapnic seizure
Authors: Majid A , Wheeler B J 
Published: July 2017

Summary
In clinical practice, seizures independent of hypoglycemia are observed in patients with type 1 diabetes mellitus (T1DM) more frequently than expected by chance, suggesting a link. However, seizures during management of diabetic ketoacidosis (DKA) have generally been considered a bad prognostic factor, and usually associated with well-known biochemical or neurological complications. We present the case of a 17-year-old girl with known T1DM managed for severe DKA complicated by hypocapnic seizure. We review the literature on this rare occurrence as well as outline other possible differentials to consider when faced with the alarming combination of DKA and seizure.

Learning points:

Seizures during DKA treatment require immediate management as well as evaluation to determine their underlying cause.

Their etiology is varied, but a lowered seizure threshold, electrolyte disturbances and serious neurological complications of DKA such as cerebral edema must all be considered.

Sudden severe hypocapnia may represent a rare contributor to seizure during the treatment of DKA.

ContextThyroid hormones modulate proliferative, metabolic and angiogenic pathways. However few studies have examined associations of thyroid hormones with cancer risk.ObjectivesTo explore associations of thyrotropin (TSH), free thyroxine (FT4) and anti-thyroperoxidase antibodies (TPOAb) with the incidence of all (non-skin) cancers and specific common cancers.Design and settingA prospective cohort study of a community-dwelling population aged 25–84 years in Western Australia.Main outcome measuresArchived sera from 3649 participants in the 1994/1995 Busselton Health Survey were assayed for TSH, FT4 and TPOAb. Cancer outcomes until 30 June 2014 were ascertained using data linkage. Longitudinal analyses were performed using Cox proportional hazards regression.ResultsDuring 20-year follow-up, 600 participants were diagnosed with non-skin cancer, including 126, 100, 103 and 41 prostate, breast, colorectal and lung cancers respectively. Higher TSH was associated with a lower risk of prostate cancer after adjusting for potential confounders, with a 30% lower risk for every 1 mIU/L increase in TSH (adjusted hazard ratio (HR): 0.70, 95% confidence interval (CI): 0.55–0.90,P = 0.005). Similarly, higher FT4 was associated with an increased risk of prostate cancer (adjusted HR: 1.11 per 1 pmol/L increase, 95% CI: 1.03–1.19,P = 0.009). There were no associations of TSH, FT4 or TPOAb with all non-skin cancer events combined, or with breast, colorectal or lung cancer.ConclusionIn a community-dwelling population, lower TSH and higher FT4 were associated with an increased risk of prostate cancer. Further studies are required to assess if thyroid function is a biomarker or risk factor for prostate cancer.

A New Class of Functions Suggested by the Generalized Basic Hypergeometric Function
Authors: Chudasama Meera H. , Dave B. I. 
Published: July 2017

We introduce an extended generalized basic hypergeometric function rΦs+p in which p tends to infinity together with the summation index. We define the difference operators and obtain infinite order difference equation, for which these new special functions are eigen functions. We derive some properties, as the order zero of this function, differential equation involving a particular hyper-Bessel type operators of infinite order, and contiguous function relations. A transformation formula and an l-analogue of the q-Maclaurin's series are also obtained.

Published: July 2017

Objetivo: explorar cómo han sido las experiencias de mujeres diagnosticadas con cáncer de cuello uterino in situ.Materiales y métodos: estudio cualitativo de tipo fenomenológico, basado en entrevistas a profundi­dad, con participación de mujeres diagnosticadas con carcinoma de cuello uterino in situ, atendidas en un hospital de segundo nivel, en un municipio del departamento de Risa­ralda, Colombia.Resultados: diez mujeres, con una mediana de edad de 23 años, no esperaban el diagnóstico y este fue devastador; asumieron como fatal su enfermedad y a sus parejas como las responsables del resultado. No muestran una clara comprensión acerca de su enfermedad. Se develan relaciones de pareja asimétricas en las cuales las mujeres no asumen activamente la protección sexual. Las mujeres cuentan con pocas redes de apoyo por el estigma que representa para ellas vivir con cáncer de cuello uterino.Conclusiones: se requiere aplicar un modelo de intervención integral que propenda por el empoderamiento de las mujeres para asumir de manera activa su enfermedad, su autocuidado y sus derechos sexuales y reproductivos, y que incluya a los varones en la prevención y atención. Es necesario que se reconozca que el cáncer uterino va más allá de síntomas como el sangrado y el dolor.

Risk and Reward: Climate Change and SPE
Authors: Judah Janeen 
Published: July 2017

President's column
In early April, the shipping lanes along the coastlines of Newfoundland and Labrador, Canada, were quite congested, but not with tankers. This area of Canada—often called “Iceberg Alley”—was filled with 450 icebergs, floating south. This overabundance appeared suddenly; the US Coast Guard reported the increase from 37 to 450 icebergs in a week.
What is the cause? Scientists disagree. Some state that rising temperatures caused by global warming triggered this massive iceberg jam. Others say that it could have been caused by a violent windstorm in St. John’s, Canada, a few weeks earlier.
In either case, the “bergy water”—the term used by the Canadian Coast Guard in its ice bulletin—has officials believing that the number of icebergs this year will eclipse last year’s total of 687.
Opinions regarding climate change—is it real or not—are polar opposite. There are just as many people who passionately believe it exists and needs to be slowed as those who do not believe it exists.
Typically, SPE does not take positions on political or controversial matters. We are a society that disseminates technical knowledge for the upstream segment of the oil and gas industry. But this concern is so prevalent globally that last year, the SPE Board of Directors formed a climate change task force to identify “key aspects of climate change and public perceptions of climate change.” This group also was charged with developing a strategy for SPE’s response and recommending any actions that the society should take.
The board also requested that recommendations developed by the task force avoid any approach that could be construed as lobbying or political advocacy, as neither is consistent with SPE’s role and status as a not-for-profit organization.
The task force worked diligently for nearly a year studying climate change policies such as the Paris Agreement, which was developed at the 21st annual Conference of Parties. Population growth and economic development are driving increased need for and access to energy, so the Paris Agreement is expected to bring change over the course of this century. It has the potential to usher in new opportunities for SPE members through deploying carbon dioxide capture, use, and storage (CCUS), further accelerating natural gas as an option to coal, changing the infrastructural load as natural gas becomes an essential component of a more flexible power generation system, and pushing oil into new markets as it is displaced from some of its current uses (such as transportation).
Getting More From Fracturing With Diversion
Authors: Rassenfoss Stephen 
Published: July 2017

Mary Van Domelen makes two key points about using diverters in fracturing designs: “It is one of the useful tools in our unconventional stimulation tool kit,” and there is a good chance “you are doing it wrong.”
Those two observations motivated the engineering adviser from Continental Resources to write “A Practical Guide to Modern Diversion Technology” (SPE 185120), a 22-page overview on effectively using diversion to more effectively fracture a well by plugging the dominant fractures to divert the pressure further down the wellbore to ensure more perforations are effectively stimulated.
Van Domelen’s paper, presented at the 2017 SPE Oklahoma City Oil and Gas Symposium, is one of a spate of recent papers by operators that show diversion is becoming a widely used part of fracturing designs, particularly in the oil-rich Bakken. The papers are coming from unconventional pioneers such as Continental and Devon Energy, smaller operators such as Liberty Resources and Abraxas, and even Saudi Aramco. All report benefits from diversion, ranging from improved production and more productive fractures to cost savings.
Liberty reported (SPE 184828) that wells in the Bakken using diversion produced twice as much as offset wells using the old method, and “33% to 39%” more than predicted by a model that uses data from comparable wells in its database of more than 10,000 wells in North Dakota.
“We are excited about what we are doing,” said Paul Weddle, completion manager for Liberty, who presented the paper at the recent SPE Hydraulic Fracturing Technology Conference. “In the oil business, there are differences (of production) of plus or minus 10% to 15%” due to local geological variations. But with gains of more than 30%, “we may be on to something.” The earliest wells using diversion have been producing for a year and continue to exceed their expectations.
Diversion has been quietly used by early adopters—Devon’s recent paper was based on changes it made in its diversion method based on testing—but in the past year the number of companies trying and using it has grown substantially.
Technology Focus: Coiled-Tubing Applications (June 2017)
Authors: Crabtree Alex 
Published: July 2017

Technology Focus
This time last year, there was uncertainty as to what the future held for our industry as a whole and the coiled-tubing sector in particular. Today, the mantra appears to be “lower for longer.” With the price of oil hovering around USD 50/bbl, is this really the case? Looking at the US Energy Information Administration (EIA) data for West Texas intermediate and Brent spot crude oil prices, it was not until 2005 that prices rose and consistently stayed above the USD 50 mark, with a short dip below that in 2008. On the cost side of the equation, the US Consumer Price Index in 2005 was 195 (1982 is the base year of 100) and 240 for 2016. Looking at US Bureau of Labor Statistics data, oil and gas extraction employment rose from 1,287,000 to 1,932,000 in the US between 2005 and 2015, peaking in 2014. Placing the coiled-tubing sector within this context, the global coiled-tubing-unit count has increased from 1,163 in 2005 to 1,951 in 2016, with the peak being 2,096 units in 2015 (Intervention and Coiled Tubing Association worldwide coiled-tubing rig count).
So what do these statistics imply? They would seem to reflect trends that are currently manifesting themselves: a decrease in activity, continuing rising costs, and a reduced return. However, even with the lower current situation, overall activity has not dropped to 2005 levels; the demand side of the curve is still trending upward. (EIA world petroleum consumption data show 84.7 million B/D in 2005 to 95.1 million B/D in 2016.) Therefore, efficiency and effectiveness will continue to be strong influencing factors in the development of the coiled-tubing market sector.
Efficiency and effectiveness can be achieved in differing ways. This year’s papers provide readers with examples of efficiencies that have been achieved in coiled-tubing operations. The papers demonstrate how problem-solving techniques have been applied to improve such aspects as on-site processes, fit-for-purpose equipment, coiled-tubing-string selection for process optimization, and more-effective treatment placement.

Paying too much or too little? Pricing approaches in the case of cross-border water supply
Authors: Banovec P. , Domadenik P. 
Published: July 2017

Abstract
Cross-border drinking water supply is often a solution for the emerging water crisis, related also to climate changes, but in several cases also a historical legacy of changing borders. It is challenged by the increased complexity of water supply management, mainly because of the doubled reality of administrative, legal, accounting and decision-making processes. Analyzed water pricing of existing cross-border utilities clearly demonstrates applied water pricing approaches mainly based on pure negotiation principles demonstrating different and often heavily asymmetric bargaining positions of partners. In order to overcome this situation applicable water pricing principles are presented. The model is demonstrated on real business cases of three water utilities from Central and South East Europe, but similar concepts are applicable for drinking water transfer between regions or municipalities in other countries.
A novel photobiological process for reverse osmosis concentrate treatment using brackish water diatoms
Authors: Ikehata Keisuke , Zhao Yuanyuan , Ma Jingshu , Komor Andrew T. , Maleky Nima , Anderson Michael A. 
Published: July 2017

Abstract
A unique aqueous silica removal process using naturally occurring diatoms for water reuse and desalination is described. Several strains of brackish water diatoms have been isolated and tested. Among them Pseudostaurosira and Nitzschia species showed promise. Reverse osmosis (RO) concentrate samples from two full-scale advanced water purification facilities and one brackish groundwater RO plant in Southern California have been successfully treated by this process. This new photobiological process could remove aqueous silica, as well as phosphate, ammonia, nitrate, calcium, iron and manganese very effectively. Under non-optimized conditions, 95% of 78 mg·L−1 reactive silica in an RO concentrate sample could be removed within 72 hours. In most cases, addition of nutrients was not necessary because the RO concentrate typically contains sufficient concentrations of macronutrients derived from the source water (i.e., treated wastewater and brackish groundwater). Preliminary characterization of organics indicated that there was no major generation of dissolved organics, which could potentially foul membranes in the subsequent RO process. This new algal process has a strong potential for its application in desalination and water reuse in the United States and around the world.

Published: July 2017

Objectives:
The present study evaluates novel cationic quinoline derivatives known as benzimidazo[3,2-a]quinolinium salts (BQS) named NBQ-48 and ABQ-48 that have structural similarities to known anti-cancer substances such as ellipticine and berberine.

Methods:
Toledo human lymphoma (ATCC CRL2631) cells were treated for 24 to 48 hours. Apoptosis related endpoints such as cell cycle arrest, mitochondrial damage, RNS and ROS generation and the activity of several apoptosis related proteins such as caspases and apoptosis inducing factor (AIF) were studied using fluorescence staining and western blot respectively.

Results:
Results indicated a higher toxicity from the amino substituted ABQ-48 versus the NBQ-48 (GI50’s of 50uM versus 100uM respectively). Both compounds induced cell death through various apoptosis related endpoints including a decrease in mitochondrial membrane potential with an increase in ROS and activation of the effector caspase 3. Interestingly, AIF release was observed on cells treated with the amino substituted ABQ-48 but not on the nitro substituted NBQ-48 samples suggesting a caspase independent mechanism for ABQ-48.

Conclusions:
The results obtained presents the toxic effects of two novel benzimidazo[3,2-a]quinolinium salts in human lymphoma tumor cells. The identified mechanism of action includes multiple apoptosis related effects. Furthermore the data presents a clear variation in caspase dependent or independent mechanism for each compound.
Causes and Timing of Maternal Death in Mizan – Tepi University Teaching and Bonga General Hospital from 2011 – 2015: A Case Control Study and Using Propensity Score Matching Analysis
Authors: Dadi Tegene Legese , Mihirete Kebadnew Mulatu , Welegebriel Tensay Kahsay 
Published: July 2017

Background:Death of women during pregnancy, delivery and within 6 weeks of postpartum can threaten the survival of the entire family. Even though our country reduces the maternal death, still the number of death that occurs is high as WHO maternal death classification. So the need of further study is unquestionable to identify cause and timing of maternal death.Methods:A case control study on 595 charts, 119 cases and 476 controls was conducted in MTU teaching & Bonga general hospital. Data was analyzed by STATA 13.1. Propensity score matching analysis was used to see causes. Confidence interval of 95% was used to see the precision and the level of significance of p value =<0.05.Result:Most death (74.8%) occurred during post-partum period. Only 17.6% of women died in Intrapartum period. The major causes of maternal death in the study area were hemorrhage 47.9% (β =0.58 (95% CI (0.28, 0.87)) in hospital but when projected to population based on our sample (β =0.26 (95% CI (0.22, 0.31)). Infection 36 (25.21%) (β = 0.50 (95% CI (0.08, 0.92))..Conclusion:Most of the women died in post-partum period particularly within three days. Hemorrhage was the leading cause of death.
O encontro com o poder salvífico de Deus na pessoa de Jesus: aproximações hermenêuticas sobre o duplo relato de curas em Marcos

Published: July 2017

O mercado religioso, em virtude da forte demanda por curas imediatas, por meio de milagres, continua em franco desenvolvimento. Mas uma pergunta se faz necessária:será que o sagrado oferecido é realmente capaz de libertar as pessoas de seus males físicos, mentais e espirituais? Nessa perspectiva, abre-se espaço para uma fecunda análise dessefenômeno que se observa em toda parte, ao longo dos séculos, inclusive dentro da religião cristã, sobretudo em tempos de crise. O presente artigo tem como objetivo ir à fonte da experiência cristã para buscar interpretar um duplo relato de curas milagrosas protagonizadas por Jesus no Evangelho de Marcos (5.21-43). Para tanto, desenvolve-se aqui uma reflexão crítica, na perspectiva literária e hermenêutica, com o intuito de dar uma contribuição aodebate em torno do tema na perspectiva bíblico-teológica.
