Mediterranean Diet attenuates risk of frailty and sarcopenia: New insights and future directions
Authors: McClure Rebecca , Villani Anthony 
Published: December 2017

AbstractSarcopenia and physical frailty are associated with progressive disability and predictive of negative health outcomes. Dietary interventions are considered the cornerstone in the management of sarcopenic symptomology and physical frailty. However few studies have investigated preventative strategies. Moreover, most studies have focused on the efficacy of individual nutrients or supplements rather than dietary patterns. The Mediterranean Diet (MedDiet) is a dietary pattern that provides evidence for an association between diet quality, healthy ageing and disease prevention. The purpose of this paper was to examine, synthesise and develop a narrative review of the current literature, investigating the potential benefits associated with adherence to a MedDiet and attenuation of physical frailty and sarcopenic symptomology in older adults. We also explored the underlying mechanisms underpinning the potential benefits of the MedDiet on ameliorating physical frailty and sarcopenic symptomology. Synthesis of the reviewed literature is suggestive of a decreased risk of physical frailty and sarcopenic symptomology with greater adherence to a MedDiet. We identified the anti‐inflammatory and high antioxidant components of the MedDiet as two potential biological mechanisms involved. Due to a lack of evidence from RCTs to support the proposed physiological mechanisms, we suggest investigating these observations in older adults with type 2 diabetes (T2DM) whom are vulnerable to physical frailty and disability. A number of biological mechanisms describing the pathway to disability in older adults with T2DM have been postulated with many of these mechanisms potentially mitigated with dietary interventions involving the MedDiet. Exploring these mechanisms with the use of well‐designed, longer‐term dietary intervention studies in older adults with an increased vulnerability to physical frailty and sarcopenia is warranted.
Regulación legal de la robótica y la inteligencia artificial: retos de futuro = Legal regulation of robotics and artificial intelligence: future challenges
Authors: Santos González María José 
Published: December 2017

Cuanto mayor sea la inteligencia artificial de los bots, robots y androides mayor será su autonomía y en consecuencia tendrán menor dependencia de los fabricantes, propietarios y usuarios. Es un hecho que la nueva generación de robots convivirá con los humanos y la legislación debe adaptarse y regular cuestiones de gran importancia jurídica cuáles son: ¿quién asume la responsabilidad de los actos u omisiones de los robots inteligentes?, ¿cuál es su condición jurídica?, ¿deben tener un régimen especial de derechos y obligaciones?, ¿qué soluciones vamos a dar a los conflictos éticos relacionados con su conducta? y por último, ¿deben establecerse medidas mínimas organizativas, técnicas y legales para minimizar los riesgos de seguridad a los que está expuesta la tecnología asumiendo que su desarrollo no debe verse como una amenaza sino como una oportunidad y que los robots pueden estar interconectados?. La regulación es un aspecto clave para la existencia de una sociedad más segura y pacífica y por ello debe estar adaptada a como es a día de hoy la humanidad y como queremos que sea en un futuro.The greater the artificial intelligence of bots, robots and androids, the greater its autonomy and consequently they will depend less of factories, owners and users. It is a fact that the new generation of robots will coexist with human. For this reason, legislation should order questions of great legal importance such as: Who takes responsibility for the acts or omissions of intelligent robots? Should it exist a special regime of rights and obligations?, what solutions will we give to ethical conflicts related to their behavior? Finally, Should we establish the minimum organizational, technical and legal measures to minimize the security risks that the technology is exposed assuming that its development should not be a threat as a threat but as an opportunity and that, the robots may be interconnected?. Regulation is a key aspect for the existence of a more secure and peaceful society and therefore it must be adapted to how humanity is today and how we want society is in the future
Clinical profile and the outcome of corrosive injury of GI tract
Authors: Velayudham Rajendran , S. Senthilkumar , Karthikeyan R. K. 
Published: December 2017

Background: Corrosive substances are common household substances that can be ingested either accidentally or intentionally with suicidal intent. The present study was conducted to analyse the clinical profile of 50 cases of corrosive injury of GI tract and to analyse the outcome of 50 cases of corrosive injury of GI tract.Methods: The Cross-sectional study was conducted on 50 cases admitted in the toxicology ward in Rajiv Gandhi Government General Hospital, madras medical college, Chennai over a period of six months. Patients with history of corrosive ingestion presenting within 24 hours of ingestion subjected to Upper GI endoscopy within 24 hours of admission. Patients presenting after 24 hours, with respiratory distress, suspected perforation either radiologically clinically and normal findings in Upper GI endoscopy were excluded. The patients were serially followed and were subjected for a re-look upper GI endoscopy after 6 weeks and the findings were compared.Results: Corrosive ingestion was more common in the age group 20-30 years and more common in males. Acid ingestion was almost twice as common as alkali ingestion. Suicidal ingestion was the most common circumstance of consumption and associated with higher grade of injury. Patients with ingestion of more than 50 ml had higher grades of injury and also were at higher risk of strictures. The spectrum of injury to the GI tract revealed esophageal injury of grade II b to be the most common finding with the duodenum being spared in majority of the cases.Conclusions: In our study, Patients with ingestion of more than 50ml had higher grades of injury and also were at higher risk of strictures. While the lesser grade injuries (0, I, IIa) were associated with complete recovery with no sequelae, the more severe grades (IIb and IIIa) were associated with higher incidence of strictures especially the circumferential lesions. Oesophageal strictures are commonly associated with suicidal corrosive ingestion. All patients with corrosive ingestion should be subjected to early UGIE and after 6 weeks to identify stricture formation.

Published: December 2017

El artículo trata del género biografía empresarial en México y consta de tres partes. En la primera, valoro lo ya escrito, que se puede catalogar o como libros de encargo –que son la mayoría y típicamente carecen de valor analítico– o como obras independientes; también explico la escasez del géne- ro biográfico en este país, a diferencia de la tradición sajona. En la segunda parte, ofrezco siete razones para considerar al género biográfico de utilidad histórica y sociológica, algunas pertinentes al ámbito mexicano y otras re- levantes al estudio de la historia en general; complemento esta sección con unas conclusiones tomadas de mi reciente libro Jenkins of Mexico (en español: En busca del señor Jenkins). Por último, sugiero cómo se puede emprender una biografía empresarial en México, con referencia a fuentes públicas, privadas, periodísticas, orales y archivísticas.

Published: December 2017

A surfactina é um lipopeptídeo da classe dos biossurfactantes, mais comumente produzida por Bacillus subtilis, uma bactéria Gram-positiva. A estrutura química da surfactina é composta por peptídeo ligado aos grupos carboxil e hidrocarboxil de ácidos graxos de cadeia longa. A produção de surfactina pode ser influenciada pela linhagem, inóculo e idade do microrganismo, além de fatores físicos como temperatura, pH, velocidade de agitação, grau de aeração, formação de espuma e concentração de oxigênio dissolvido e fatores nutricionais, como fontes de carbono, nitrogênio e elementos-traço nos meios de cultivo. As potenciais áreas de aplicação desse biossurfactante são terapêuticas e ambientais. Neste trabalho tem-se como objetivo abordar aspectos estruturais, fatores envolvidos na produção por microrganismos e as áreas de aplicação da surfactina. Palavras-chave: Aplicações. Estrutura.

Evolución geohistórica de la morfología urbana de Ambalema, Tolima, Colombia
Authors: Páez Trujillo Douglas David 
Published: December 2017

El objetivo principal de la investigación consistió en analizar la configuración de la estructura socio-espacial de Ambalema, Tolima, a lo largo de su historia. La metodología empleada se basó en una operacionalización cualitativa, con un diseño descriptivo-explicativo y uso del método analítico. Los resultados alcanzados permiten establecer que el valor de la localización ha variado conforme lo ha hecho la importancia del río Magdalena, en cuya margen izquierda la ciudad ha sido emplazada dos veces; la Situación presenta una sucesión alternada de posicionamientos regionales favorables y desfavorables, siendo los desfavorables los que han predominado en el tiempo; el valor del Emplazamiento y la favorabilidad de la Situación han afectado el desarrollo de las Funciones Urbanas, y estos, a su vez, se ven afectados por la ampliación o disminución de las funciones; la evolución del Plano evidencia la irregularidad de su trazado y el crecimiento lento pero continuado del espacio material.

Coca and identity in alison spedding’s el viento de la cordillera
Authors: Jackson Dorian Lee 
Published: December 2017

The article examines the treatment of region and ethnicity in Alison Spedding’s 2003 novel, El viento de la cordillera: un thriller de los 80, to show how the articulation of the Yungas region crafts a distinctive Bolivian narrative of narcotrafficking and traditional coca production in the 1980s. The analysis highlights the narration of the tension between contemporary cocaine paste production and traditional coca leaf cultivation in the Andean region. Further, the study examines how the presence or absence of “outsiders” in the Yungas help produce an example of Bolivian narcofiction. Finally, the study examines Spedding’s creation of a strong female indigenous protagonist as a form of resistance and subversion of the foreign demand for illicit drugs.
Special Issue on Educational Robotics
Authors: Fujisawa Shoichiro , Kotosaka Shinya , Iribe Masatsugu , Okugawa Masayuki 
Published: December 2017

This is the 2nd special issue on education of robotics & mechatronics on Journal Robotics & Mechatronics. Six years have passed since the previous issue (Vol.23, No.5) was published. This special issue includes nine research papers and two review papers, among which four research papers focus on the utilization of robots in STEM education, which has been spotlighted recently, and programming education for the young. Five research papers propose educational methods with novel, unprecedented ideas, and the two review papers overview technology education in Japan. The review papers focus on STEM education that utilizes a variety of manufacturing methods that have become familiar, and they present a variety of efforts being made in STEM education, programming education in today’s Japan.
At present, Germany’s Industry 4.0, Japan’s Robot Strategy, and many other initiatives are being undertaken in the world to promote development technology as it relates to production automation and efficiency. The development of human resources that are capable of working with these new technologies has also gathered public attention, with each educational institution now required to enrich its STEM education. As part of this movement, in 2020, programming education will be added to Japan’s elementary school curriculum, with robots being the focus of the education. This situation indicates that the importance of educational robotics is likely to continue to increase in the future. We expect that this special issue will contribute to the development of educational robotics communities and of human resources that are well prepared in the field of robotics.
We would like to express our sincere gratitude to all contributors and the reviewers for making this special issue possible.
Technology Update: System Cuts P&A Cost by Creating Rock-to-Rock Barrier in One Trip
Authors: McNicol Jim , Stokkeland Thore Andre 
Published: December 2017

Technology Update
Traditional well plugging and abandonment (P&A) methods are not efficient. For example, section milling is time-consuming and expensive because of the number of rig days required. The milling produces cuttings, which have to be handled. Contamination of the milling fluid with oil-based mud (OBM) requires separation before disposal. Cutting casing requires pulling it from the hole. Handling tubulars has numerous inherent risks, and removing old tubulars, especially, could bring up naturally occurring radioactive material from the subsurface.
Decommissioning a well must always achieve permanent integrity, and central to this is the successful placement of a rock-to-rock cement barrier. Creating such a barrier, without section-milling or retrieving and pulling the casing, offers a major cost advantage over traditional methods.
Developed by Archer, the Strong-hold Barricade system (Fig. 1) leaves the casing in situ. The system perforates, washes, and cements the annulus, creating a rock-to-rock barrier in one trip (Fig. 2).
In addition, the system reduces personnel risk, in part by reducing the number of individuals required. For example, not having to pull casing eliminates the casing crew and tong operations. The system only requires a single tool operator and the cementer, who would normally be present on the rig to pump the cement.
Specialized Technologies
Two features are central to this system. First are the firing heads. Most conventional firing heads are operated by annular pressure. For this system, the company developed a firing head that is operated by tubing pressure.
A contingency system with multiple sets of guns can also be used. If the first set of guns fails to create the required injection ports, the second set can be fired by annular pressure without pulling out of the hole.
The second feature is the creation of a cement base to contain the cement plug above. The cement base is effectively an integrated bridge plug. Situated immediately above an auto-gun release, the cement base is activated after the guns are released and the tool is run to below the perforated interval to provide a secure base for the cementing operation.
The cement base is set by pressuring up on a dropped ball. A pull test and further pressure then releases the base from the string. The dropped ball is retained in the base, leaving the pipe with no restriction.
Water Demand Spurs Permian Infrastructure Investment
Authors: Whitfield Stephen 
Published: December 2017

The production growth in the Permian Basin has created a new dilemma for operators looking for cost efficiency. In September Bloomberg predicted that Permian production could rise from its present level of 2.4 million BOPD to 10 million BOPD, a rate that could produce up to 50 million B/D of flowback water. With the WTI price at around $57/bbl in early December, disposal of that flowback water can be expensive. Bloomberg estimated the cost of the service is between $1.50 to $2.50/bbl.
While this predicted spike in water volume may be an issue for operators, it is an opportunity for oilfield water management companies working in the region. With demand for their services going up, these companies have already begun acquiring pipeline infrastructure, saltwater disposal (SWD) wells, and facilities.
Multi-Basin Strategy
With water management becoming a critical issue for operators in the Permian, midstream companies have been aggressive with mergers and acquisitions in their efforts to bolster their positions. H2O Midstream’s acquisition of Encana’s produced-water-gathering system last June gave it control of more than 100 miles of interconnected pipeline and five SWD wells with a total permitted disposal capacity of 80,000 BWPD. In September 2017, RRIG Water Solutions announced the acquisition of a 475-mile pipeline from Oilfield Water Logistics. Located in the eastern part of the Delaware Basin, the pipeline has the potential to move more than 2.3 million B/D of fresh water.
WaterBridge Resources is another company that has been active in the Permian region. Since its founding in 2015, the midstream development company has focused on acquiring and operating flowback and produced water infrastructure for various oil and gas producers, including water sourcing, gathering, reuse, pipeline infrastructure, and disposal infrastructure.
In August 2017, WaterBridge acquired EnWater Solutions, a company whose current assets include more than 100 miles of gathering line and nearly 150,000 B/D of permitted disposal capacity. WaterBridge plans to extend EnWater’s existing gathering business into a full-cycle, closed-loop water sys-tem, and by the end of 2018 the company expects to have more than 300,000 B/D of disposal capacity and 200 miles of interconnected gathering pipe.
“The assets we acquired from EnWater are located in the southern Delaware, and the EnWater team’s expertise encompasses the entire Permian region from the Delaware to the Midland, so that was a regional platform with an existing management team that are certain areas across the US where the water/oil ratio is much greater. The Eagle Ford is fairly dry, the SCOOP/STACK is fairly wet, and the Permian’s fairly wet. The water/oil ratios are what we chase because, at the end of the day, our business is a volumetric business. The greater the volumes of water to be handled, the better our profitability is.”
