Ethyl 2-hydroxy-3-methylbutanoate enantiomers: quantitation and sensory evaluation in wine
Authors: Gammacurta Marine , Tempere Sophie , Marchand Stéphanie , Moine Virginie , De Revel Gilles
Published: April 2018

Aim: To investigate chemical and sensory characteristics of ethyl 2-hydroxy-3-methylbutanoate in wines.Methods and results: Ethyl 2-hydroxy-3-methylbutanoate has been recently identified as a potential marker of lactic acid bacteria esterase activity. Enantiomers of this fruity ester were quantitated in 99 wines from various vintages and French regions using chiral gas chromatography (γ-cyclodextrin phase). Analyses revealed the predominant presence of the R enantiomer in red and white wines, with a maximum R/S enantiomeric ratio of 94/6 in a 1993 red wine. Results also highlighted greater levels of the ester in red than white wines, depending on grape origin. The detection thresholds of the R- and S-form were estimated at 4 µg/L and 1.5 µg/L in water and 51 mg/L and 21 mg/L in red wine, respectively. Moreover, ranking tests made with levels found in wines did not show significant sensory differences.Conclusion: The concentrations found in wines were considerably below the detection threshold, indicating no direct effect of these compounds on fruity aroma modulation. The absence of significant difference in sensory tests demonstrates that ethyl 2-hydroxy-3-methylbutanoate does not contribute significantly to the fruity aroma of red wine.Significance and impact of the study: To our knowledge, no previous research had determined the enantiomeric distribution and the sensory characteristics of this compound in wine.

US Gulf of Mexico Production Projected To Hit Record High
Authors: Whitfield Stephen
Published: April 2018

The deepwater US Gulf of Mexico (GOM) sector has struggled since the onset of the oil price downturn in 2014, but as costs settle and operators establish new standards for running efficient projects, this year may be a significant turning point for the industry in the region.

In January, Wood Mackenzie published a report predicting that production of oil and gas in the deepwater GOM will reach an all-time record high this year, with more than 1.9 million BOPD, surpassing the previous record set in 2009 by nearly 10% and representing 13% growth year over year.

William Turner, Wood Mackenzie’s senior research analyst and lead author of the report, Deepwater GoM: 5 Things to Look for in 2018, said that, more than 2 months into the calendar year, the level of activity in the region is still on track to meet expectations. However, recent developments may have an effect on that trajectory.

Policy Impacts

In January, the US Department of the Interior (DOI) announced a proposal to place more than 90% of federal offshore land containing oil and gas—including land in the GOM—up for auction between 2019 and 2024. In February the DOI’s Royalty Policy Committee issued a recommendation for lower royalty rates for offshore oil and gas drilling on sea-bed owned by the US government.

If approved, royalties from off-shore drilling would drop from 18.75% to 12.5%, the lowest royalty rate per-mitted. The US Bureau of Ocean Energy Management (BOEM) had already relaxed royalty rates to 12.5% for some shallow-water leases in August 2017.

With the WTI and Brent crude prices still hovering in the low $60s as of early March amidst relatively high supply, the recommendation could make it more attractive for operators to look at bidding for offshore oil leases in the GOM.

Turner said while the decision on the royalty came faster than anticipated, it is likely the US federal government wanted it in place before Lease Sale 250 on 21 March. At the time of this writing, it was scheduled to be the largest regionwide sale in US history, with 77.3 million acres offshore Texas, Louisiana, Mississippi, Alabama, and Florida avail-able for exploration and development. The sale includes approximately 14,700 unleased blocks located in the GOM’s Western, Central, and Eastern planning areas. The BOEM estimated that these blocks contain about 90 billion bbl of undiscovered technically recoverable oil and 327 Tcf of undiscovered technically recoverable gas.

The royalty rate may have a bigger impact on operators’ decision making in the coming months. For instance, Turner said it is possible that Total may try to rebid for leases in the North Platte field—where it holds a 40% working interest—rather than taking over operation of its holdings from Cobalt International Energy.
Additive Manufacturing Makes Waves in Industry
Authors: Whitfield Stephen
Published: April 2018

Over the past few years additive manufacturing (AM) technology has grown in popularity as companies explore its potential. Applying layer upon layer of polymers can create objects of almost any shape and geometry guided by design files, and now, recent developments have made it possible to print metal parts and components, making it a potentially disruptive innovation for the supply chain.

AM has already had an impact on other industries such as aviation—Air-bus agreed in October to a deal to manufacture polymer parts for use on its A350 XWB aircraft—and now, as oil and gas companies look to adopt AM into their supply chain management, service companies are breaking through with new machines and processes that may facilitate larger-scale production of parts and components in the future. In addition, a new guideline has been established to help bridge the gap between the quality assurance of parts created by an AM process and those created through traditional manufacturing processes.

Additive Manufacturing Qualification

In November, DNV GL published its first classification guideline for the use of AM in maritime and oil and gas. The guideline was designed to bridge the gap between the quality assurance of parts and components created by an AM process and those created through traditional manufacturing processes by creating a clear pathway for AM certification. The guideline serves as an umbrella document that establishes the overall framework process for qualification and certification of AM products and further points to other DNV specific services/documents that are relevant in assessing parameters that will impact the final product, from the materials used to the actual printing and post-processing.

Brice Le Gallo, DNV’s regional manager for Southeast Asia and Australia, said the lack of a guideline was one of the more significant hurdles for more widespread adoption of AM processes. Because there are currently only a handful of AM standards, companies often conduct their own testing to ensure integrity of the equipment, parts, and components. The cost and time needed to conduct these tests deters wider adoption. In addition, AM processes typically incur higher material and machining costs than conventional manufacturing. He said the new guideline will help provide a blueprint that may encourage further adoption.

“Today what we see is that the level of adoption in these industries, maritime and offshore oil and gas, is still quite low. One of the areas where we can really help the industry get the level of adoption increased is on the qualification side,” Le Gallo said. “This is one of the most important hurdles. We think that by bringing appropriate qualification frameworks to the industry, we will see an important increase in the level of adoption. This would then lead to greater volume, which in turn would lead to costs going down.”

Geoarchaeological analysis of Mousterian settlements in the upper part of the Eresma river valley: Abrigo del Molino (Segovia, Spain)
Authors: Álvarez-Alonso D. , De Andrés-Herrero M. , Díez-Herrero A. , Rojo Hernández J.A.
Published: April 2018

The absence of systematic archaeological investigations in the upper part of the Eresma River valley has resulted in this area being considered as an empty space during the Palaeolithic. This paper presents the first results of the project the ‘First Settlers of Segovia’, where the geoarchaeological approach has not only allowed the discovery of Mousterian sites such as the Abrigo del Molino, but has also allowed the contextualization of the first human occupation of this area of the Eresma River valley from a chrono-cultural and paleoenvironmental point of view. Undoubtedly, the excavations at this site are the main source of information for this analysis. Furthermore, new results obtained during the excavations in the upper part of Abrigo del Molino and in the recently discovered site of the San Lázaro cave, together with the data of the surveys performed in this area are also providing new information on the geoarchaeological interpretation of the first human occupations in the upper part of the Eresma River valley.
Las Hoyas in the “dehesa” of Cañal (Salamanca, Spain), an ancient sedimentary gold mining excavation
Authors: González-Clavijo E.J. , González de Carballo J.M. , Barrios S. , González-Clavijo E.
Published: April 2018

The site known as Las Hoyas, in the municipal area of Pelayos (Salamanca), is a large open-cast mining pit of great antiquity, where sedimentary gold was exploited. Its typology corresponds to that used in traditional Roman mining, but nearby ruins belong to a Visigothic hamlet. The presence of several Roman settlements, roads and bridges in the area, joined to ruins with names of possible Roman origin, not yet studied, suggest the mine was active during the height of the Roman Empire. The sediments bearing the gold are continental of Cenozoic age (Oligocenic) and fill a tectonic groove of Alpine origin confined by SW-NE main faults and NW-SE secondary faults. The source area is the close reliefs placed to the SE, which are the first buttresses of the Spanish Central System.

Health-Related Internet Use by Children and Adolescents: Systematic Review (Preprint)
Authors: Park Eunhee , Kwon Misol
Published: April 2018

BACKGROUND

The internet is widely used by children and adolescents, who generally have a high level of competency with technology. Thus, the internet has become a great resource for supporting youth self-care and health-related services. However, few studies have explored adolescents’ internet use for health-related matters.

OBJECTIVE

The objective of this systematic literature review was to examine the phenomenon of children and adolescents’ health-related internet use and to identify gaps in the research.

METHODS

A total of 19 studies were selected from a search of major electronic databases: PubMed, Cumulative Index of Nursing and Allied Health Literature, and PsycINFO using the following search terms: “health-related internet use,” “eHealth,” “Internet use for health-related purpose,” “Web-based resource,” “health information seeking,” and “online resource,” combined with “child,” “adolescent,” “student,” “youth,” and “teen.” The children’s and adolescents’ ages were limited to 24 years and younger. The search was conducted from September 2015 to October 2017. The studies identified to contain youth (<24 years) health-related internet use were all published in peer-reviewed journals in the past 10 years; these studies examined general internet use seeking health care services, resources, information, or using the internet for health promotion and self-care. Studies were excluded if they explored the role of the internet as a modality for surveys, recruitment, or searching for relevant literature without specifically aiming to study participants’ health-related internet use; focused solely on quality assurance for specific websites; or were designed to test a specific internet-based intervention.

RESULTS

Interesting patterns in adolescents’ health-related internet use, such as seeking preventative health care and specific information about medical issues, were identified. Quantitative studies reported rates of the internet use and access among youth, and the purpose and patterns of health-related internet use among youth were identified. A major objective of health-related internet use is to gain information, but there are inconsistencies in adolescents’ perceptions of health-related internet use.

CONCLUSIONS

This study’s findings provide important information on how youth seek information and related support systems for their health care on the internet. The conceptual and methodological limitations of the identified studies, such as the lack of a theoretical background and unrepresentative samples, are discussed, and gaps within the studies are identified for future research. This review also suggests important features for potential Web-based health interventions for children and adolescents.
Analysis of Content Shared in Online Cancer Communities: Systematic Review (Preprint)
Authors: van Eenbergen Mies C , van de Poll-Franse Lonneke V , Krahmer Emiel , Verberne Suzan , Mols Floortje
Published: April 2018

BACKGROUND

The content that cancer patients and their relatives (ie, posters) share in online cancer communities has been researched in various ways. In the past decade, researchers have used automated analysis methods in addition to manual coding methods. Patients, providers, researchers, and health care professionals can learn from experienced patients, provided that their experience is findable.

OBJECTIVE

The aim of this study was to systematically review all relevant literature that analyzes user-generated content shared within online cancer communities. We reviewed the quality of available research and the kind of content that posters share with each other on the internet.

METHODS

A computerized literature search was performed via PubMed (MEDLINE), PsycINFO (5 and 4 stars), Cochrane Central Register of Controlled Trials, and ScienceDirect. The last search was conducted in July 2017. Papers were selected if they included the following terms: (cancer patient) and (support group or health communities) and (online or internet). We selected 27 papers and then subjected them to a 14-item quality checklist independently scored by 2 investigators.

RESULTS

The methodological quality of the selected studies varied: 16 were of high quality and 11 were of adequate quality. Of those 27 studies, 15 were manually coded, 7 automated, and 5 used a combination of methods. The best results can be seen in the papers that combined both analytical methods. The number of analyzed posts ranged from 200 to 1,500,000; the number of analyzed posters ranged from 75 to 90,000. The studies analyzing large numbers of posts mainly related to breast cancer, whereas those analyzing small numbers were related to other types of cancers. A total of 12 studies involved some or entirely automatic analysis of the user-generated content. All the authors referred to two main content categories: informational support and emotional support. In all, 15 studies reported only on the content, 6 studies explicitly reported on content and social aspects, and 6 studies focused on emotional changes.

CONCLUSIONS

In the future, increasing amounts of user-generated content will become available on the internet. The results of content analysis, especially of the larger studies, give detailed insights into patients’ concerns and worries, which can then be used to improve cancer care. To make the results of such analyses as usable as possible, automatic content analysis methods will need to be improved through interdisciplinary collaboration.
Impact of vertical sequence on consumers' choice between hedonic and utilitarian products
Authors: Tong Luqiong , Su Song
Published: April 2018

Given that display patterns greatly impact consumers' product evaluations and choices, we investigated how vertical sequence influences consumers' self-control behavior regarding choosing between hedonic and utilitarian products. We first conducted a pretest to examine whether or not
vertical display sequence influenced product preference when the products presented belonged to the same category. In Study 1, we then tested the basic effect of vertical sequence on the choice between hedonic and utilitarian products. Finally, we conducted Study 2 to examine the underlying
mechanism of the impact of vertical sequencing on the choice between hedonic and utilitarian products. Results showed that when hedonic and utilitarian products were jointly presented and when the hedonic (vs. utilitarian) product was placed at the top (vs. bottom), consumers were more likely
to realize the difference in experiential benefits between the hedonic and utilitarian products and, thus, were more likely to choose the hedonic (vs. utilitarian) product.

Authors: Bulğay Celal , Çetin Ebru
Published: April 2018

The purpose of the study is to compare the physical, motor and physiological features of students in the age group of 12-14 years old who regularly practice in athletics and wrestling sports with non-sports students, and explore its impacts on the sports students' level of branching. The research group was selected among Keçiören Mecidiye Secondary School and Alaeddin Ozdenören Imam Hatip Secondary School students in Ankara. The research group consisted of 47 students; 15 students in the age group of 12-14 years old who are engaged in regular athletics training, 17 students in the same age group who are engaged in regular wrestling training and 15 volunteers in the same age group who do not do sports. Measurements included age, height, body weight, Agility (T-test), hand grip strength, standing jump, vertical jump, body fat percentage, flamingo balance, flexibility, 1 min shuttle, BMI, 30 m speed run, 1000 m run-walk tests. The analysis of the data was evaluated according to the results of the Levene test for homogeneity. If the result was homogeneous, ANOVA method, otherwise Kruskal Wallis comparison test was used. In variables whose averages differed as result of multiple comparisons, the TUKEY test was used to find which groups these differences stemmed from. The results of agility, right and left hand grip strength, flexibility, 1 min shuttle, Body Mass Index (BMI), 30 m speed, 1000 m run-walk tests were statistically significant. However, the results for height, weight, age, long jump, flamingo balance, body fat percentage, vertical jump tests were not statistically significant. When we look at the results, it is found that the best results for 1000 m run-walk, 30 m speed run, agility (T-test), height, long jump, vertical jump were recorded in the athletics group. It has been observed that the wrestler group has better results in body weight, body fat percentage, grasp strength, flamingo balance, 1 minute shuttle and flexibility parameters. The values of the control group were found to be lower than those who were engaged in athletics and wrestling as they did not exercise regularly. When the differences between the groups are evaluated, it can be said that there is a tendency towards branching in a branch in the age group of 12-14 years old.

Published: April 2018

Body physique and physical fitness are the key determinants of a healthy life. The type of work one performs has immense impact on the physique and fitness of an individual regardless of even socio-economic status. This study aims to understand the association of physical fitness with body physique among a tribal community of India. Data were collected on 200 individuals, both male and female in the age group of 18-40 years using random sampling technique. The males are mesomorph ectomorph (1.6 - 4.0 - 3.5), whereas, females are central (2.8 – 3.6 – 3.5). The physical fitness level of the studied population is excellent. With an increase in physical fitness among Warli males and females, there is an increase in mesomorphy component of somatotype, while the inverse is true for endomorphy and ectomorphy components. From this, it can be inferred that to be physically fit, muscular development is the most important.

Authors: Armaghani Taher , Kasaeipoor Abbas , Mohammadpoor Usef
Published: April 2018

This paper studies the effect of a constant magnetic field on the mixed convection heat transfer and the entropy generation of CuO-water nanofluid in an open C-shaped cavity with a numerical method. The governing equations are presented by control volume method and they are solved simultaneously by the SIMPLE algorithm. This study examines the effect of the Hartman number, aspect ratio, Reynolds number, and Richardson number parameters for different solid volume fraction of nanoparticles. Also Nusselt number, entropy generation, thermal performance criteria and coefficient of performance is studied in this research. The calculated parameters are the Hartman number, aspect ratio, Reynolds number, Richardson number, nanofluid solid volume fraction, Nusselt number, and coefficient of performance. The results show that increasing the Hartmann number reduces the entropy generation. However, the thermal performance increases. Increasing the aspect ratio raises heat transfer and thermal performance. The effects of nanofluid solid volume fraction on mixed convection heat transfer and entropy generation are also investigated and discussed.

Pelayanan publik di Indonesia dituntut untuk memberikan pelayanan yang prima. Di tengah upaya mewujudkan usaha tersebut, Aparatur Sipil Negara (ASN) merepresentasikan diri sebagai pihak yang perlu ditakuti atau menggunakan jabatan sebagai kekuatan untuk menekan masyarakat. Reorientasi nilai-nilai kepemimpinan dianggap sebagai pendekatan strategi untuk membentuk kualitas kepemimpinan ASN. Tulisan ini mendiskusikan kepemimpinan profetik perspektif Islam beserta cara memfasilitasinya. Argumen utamanya adalah kepemimpinan profetik aplikabel dengan birokrasi publik di Indonesia. Kami telah menggunakan data skunder yang berasal dari berbagai jurnal dan buku. Al-Qur’an dan praktik kepemimpinan Nabi Muhammad SAW juga menjadi sumber rujukan. Kajian ini mampu menjelaskan konstruk kepemimpinan profetik perspektif Islam dan dari sisi teori kepemimpinan. Kemudian diketahui bahwa pemicu kepemimpinan profetik dapat dari hasil meneladani Nabi Muhammad SAW dan juga melalui pengalaman sosial. Proses pembentukannya berlangsung dalam waktu yang lama, maka disimpulkan bahwa kepemimpinan ini berpeluang sukses dalam birokrasi ketika ASN memiliki kematangan beragama. Upaya mewujudkan kepemimpinan profetik dapat dimulai dengan menganalisis tingkat kematangan keberagamaan. Menghadirkan nuansa spiritual dalam organisasi dinilai cukup memfasilitasi ASN yang telah matang beragama. Sebaliknya, pemimpin puncak perlu mereorientasi nilai dalam visi dan tujuan bekerja. Tulisan ini juga memandang perlunya meninjau kembali praktik seleksi CPNS karena praktik yang ada cenderung melupakan sisi spiritualitas.

Bahasa SMS dari Segi Grafologis, Sintaksis, dan Psikolinguistik
Authors: Morelent Yetty
Published: April 2018

The widespread use of celular phones and SMS has spawned a variety of new word formation. These new words raise a language variety that leads to various interpretations. This is because the abbreviations and perpetuate sentences tend to "violate" graphological and syntactic rules, and the influence of psycholinguistics in the use of these abbreviations. This is because the creativity of the language community is very expressive and subjective regardless of the linguistic acceptability. The unacceptability is caused by the irregular shortenning of words. Keywords: SMS language, graphologist, syntax, psycholinguistics

The implementation of SOP (Standard Operational Procedures) in university library is needed to improve the service quality. The arrangement of SOP in University library includes four stages. The first is analysis of SOP needs. The beginning step in arranging of SOP is by analyzing SOP that will be created. Furthermore, the SOP that created depends on the ongoing work condition and procedures. The second is the development of SOP. Because of the change of internal and external organization of university library, SOP also has to change. The third is implementation of SOP. In implementing SOP, it is hoped that there is a balance between the availability of SOP, that organizes the operational activity of university library, and the human resources, that have professional behavior in arranging the library. The fourth is observation and evaluation. In order to implement SOP properly, it should be assessed by reviewers. These four steps are done in sequence to produce SOP that is appropriate to field needs for supporting the completeness of integrated quality management in university library. Therefore, the standard service quality of library can be measured by having SOP. Thus, the service quality which is given to visitors can be determined based on SOP.
