AbstractWhen planning for the future, media managers must balance realism with the need to foresee unexpected changes. This article investigates images of the future in the Norwegian media industry in the early years of the 21stcentury and identifies five key trends that media managers envisioned:personalized content, user-generated content, rich media, cross-platform media, andmobility. We argue that increased reflection on such visions and how they are formed may put managers (and researchers) in a better position to meet the future. We therefore ask to what degree they were influenced by actual developments at the time, or anchored in more classical imagery of the future. The analysis illustrates how new technologies become focal points for articulating old dreams about the future. At the latest turn of the century, the mobile phone served as such a focal technology.
Profiling Suspensions in Natural Water by a Simplified Dynamic Light Scattering Procedure and Sedimentation
Authors: Chicea Dan , Chicea Liana-Maria 
Published: February 2017

Abstract
A coherent light scattering experiment was carried out. The samples were aqueous natural water suspensions picked from the same river. While sedimentation occurred in the samples, they were subjected to a dynamic light scattering (DLS) experiment and the time series was recorded at certain time intervals. For each recording, a program written for this purpose, performing at least square minimisation, computed the average diameter of the particles in suspension. The variation of the average diameter in time indicates the dominant type of suspensions in water.
Engineers Need To Learn From History Because the Industry Tends To Repeat It
Authors: Rassenfoss Stephen 
Published: February 2017

In the 2 years since oil prices plunged, job cuts and retirements have changed the face of petroleum engineering. SPE’s membership mix has shifted to younger, with the biggest numbers in their 20s and 30s.
“We have seen most of the older generation wiped out. It is pretty scary seeing the people being asked to leave” who have so much knowledge, said Tom Blasingame, the technical director for reservoir description and dynamics.
There are still Baby Boomers left in the ranks, and they want to pass on what they have learned from experience. The seven SPE directors interviewed for this story began their careers during the long-lasting funk that began in the early 1980s and lingered through the 1990s. At last year’s SPE Annual Technical Conference and Exhibition (ATCE) in Dubai, they offered their perspectives in a discussion titled “The Way to Move Forward is to Look Back.”
While the oil market seems to have settled into a narrow range and the pace of layoffs slowed later in the year, these are still hard times.
“Unfortunately a lot of people are losing their jobs; that is happening across the world and across the industry, even in national oil companies,” said Hisham Saadawi, technical director for production and facilities. “The perception is prices will remain like this now.”
The pressure to cut costs remains intense, including personnel budgets. Even some top students from Texas A&M University are hearing from companies that “we do not have the budget to hire now,” said Blasingame, a petroleum engineering professor at Texas A&M, adding that for many, “the anxiety meter is off the scale.”
Fewer students are enrolling in petroleum engineering programs in the US and elsewhere because it no longer ensures a good-paying job, with some schools seeing declines of 50% or more in their incoming classes.
“There is no panic. I am sensing the biggest concern is the job situation for graduates. That is pretty tough in many places,” said Dan Hill, director for academia. For the faculty in many programs, there is a positive side to the declines in enrollment: the lowering of class sizes to more desirable levels.
Risk-Based Abandonment-Prioritization Strategy for Inactive Subsea Wells
Authors: Wilson Adam 
Published: February 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 181020, “Risk-Based Abandonment-Prioritization Strategy for Inactive Subsea Wells,” by Abimbola Oladipo, Maersk Oil North Sea UK, and Adrian Houlbrook, DNV GL, prepared for the 2016 SPE Intelligent Energy International Conference and Exhibition, Aberdeen, 6–8 September. The paper has not been peer reviewed.
This paper describes how an exploration-and-production company successfully developed and applied a qualitative risk-based abandonment-prioritization strategy for an inventory of inactive subsea wells. The exercise entailed a qualitative-assessment methodology using 25 well-integrity-related criteria. An aggregate of weighted scores was subsequently applied to the company’s corporate risk-assessment matrix on the basis of the escalation potential in the event of a loss of containment. The results clearly highlighted the wells with the highest risks.
Well History
The inactive subsea wells relevant to the exercise are distributed across the central North Sea in water depths ranging from 244 to 474 ft. These normal-pressure/normal-temperature subsea wells are all located in the mature UK Central North Sea offshore basin and were completed in relatively benign reservoirs with comparatively low corrosion susceptibility.
Each inactive subsea well evaluated had functioned earlier in its life as an oil producer (with gas lift capability), water injector, or aquifer well. The majority of these subsea wells were shut in and disconnected from their flowlines and hydraulic-control and data-acquisition systems. However, the wells’ physical isolation from the flowlines and great distance from the host installation meant that they presented negligible safety risks to personnel onboard the installations.
Methodology
Because degradation is not driven solely by age, and having recognized that each well behaves differently, the methodology (Fig. 1) required each well to be assessed on the basis of evidential information presented and in accordance with how closely the well followed the corporate standard ideal integrity model of its well type. A specific set of scoring guidelines was developed and reflected corporate risk-management protocols to achieve a consistent, fair, and accurate risk ranking. These guidelines were based on a number of factors, including but not limited to the technical integrity of key elements, evidential documentation, field service history, incident records, and well-integrity maintenance records.
An initial classification was applied on the basis of the available design life of key surface equipment (in this case, subsea horizontal spool trees and wellheads) and well functionality, thus enabling each well to be classified broadly into one of three preliminary-risk-assessment categories: high, medium, or low.
Biologiczne aspekty śródoperacyjnej radioterapii i roli płynów pooperacyjnych w terapii raka piersi

Published: February 2017

W ciągu ostatniego stulecia radykalna mastektomia stanowiła główną metodę terapii pacjentów z nowotworem piersi. Dopiero pod koniec dwudziestego wieku mastektomia została zastąpiona przez zastosowanie oszczędzającego zabiegu chirurgicznego połączonego z frakcjonowaną radioterapią zewnętrzną (ang. external beam radiation therapy, EBRT), co znacznie obniżyło ryzyko wystąpienia u pacjentów wznowy miejscowej [1]. Pomimo osiągania dobrych wyników leczenia bez występowania ciężkich skutków ubocznych, czas trwania terapii EBRT stanowi poważne ograniczenie. Pacjenci mieszkający w dużej odległości od ośrodka radioterapii lub pacjenci wycieńczeni po przebytej chemioterapii często nie otrzymują radioterapii po wycięciu guza lub poddawani są zabiegowi mastektomii [2]. Rozwiązaniem tego problemu może być zastosowanie śródoperacyjnej radioterapii (ang. intraoperative radiotherapy, IORT), która podawana jest w jednej dawce w trakcie zabiegu chirurgicznego do loży po wycięciu guza. Rezultaty badań klinicznych ELIOT i TARGIT-A pokazały, że zastosowanie tej metody w odpowiednio wyselekcjonowanej grupie pacjentów może przynieść lepsze wyniki niż zastosowanie techniki EBRT [3, 4]. Jednak efekty działania śródoperacyjnej radioterapii na mikrośrodowisko guza nie są dobrze poznane. Wykazano, że proces zapalny wywołany zabiegiem chirurgicznym może stymulować wzrost pozostałych po zabiegu operacyjnym komórek nowotworowych [5]. Co więcej, najnowsze wyniki badań sugeruje, że proces ten może być hamowany poprzez zastosowanie radioterapii [6]. Lepsze zrozumienie interakcji zachodzących pomiędzy komórkami nowotworu piersi i mikrośrodowiskiem guza w odpowiedzi na napromieniowanie może pozwolić na odkrycie nowych strategii terapii nowotworów piersi.
Electrochemical Sensor‐Based Ruthenium Nanoparticles on Reduced Graphene Oxide for the Simultaneous Determination of Ethinylestradiol and Amoxicillin

Published: February 2017

AbstractThe composite material of reduced graphene and Ru nanoparticles (rGO/RuNP) was obtained by electrochemical oxidation of ruthenium nanoparticles immobilised on the glassy carbon electrode (GCE) surface and used for simultaneous electroanalysis of drugs. There are many discussions in the scientific community about the decrease in therapeutic efficacy of contraceptives when associated with antibiotics. The antibiotic effect of the antagonist can increase the contraceptive excretion levels in urine, indicating a reduction in the body and thus a decrease in the desired effect. Using the DPV technique, it was possible to quantify ethinylestradiol (EE2) and amoxicillin (AMX) with a linear response range, 5.50x10−8 – 1.20x10−6 mol L−1, and LOD, 2.04 nmol L−1 and 1.63 nmol L−1, respectively. The results for the electrochemical behaviour of EE2 and AMX using GCE/rGO/RuNP were compared with GCE/rGO and GCE. The GCE/rGO/RuNP showed greater stability and separation anodic peak currents, suitable for the quantification of organic molecules in samples of environmental interest, as well as clinical and food samples.

Published: February 2017

Abstract
A simple method for calculating the productivity of chromatography processes was proposed based on the iso-resolution curve concept. The model separation system was polyphenol separations by polystyrene divinylbenzene resins with the ethanol–water mixture mobile phase. The distribution coefficient K was determined as a function of ethanol concentration I by linear gradient elution experiments. The HETP-mobile phase velocity u curves were determined as a function of I. Using K and HETP, the iso-resolution curve was calculated, from which the productivity was determined as a function of I. It was found that there is an optimum I, where the highest productivity with the minimum amount of mobile phase consumption is obtained.
Changes in vegetation phenology are not reflected in atmospheric CO2 and 13C/12C seasonality

AbstractNorthern terrestrial ecosystems have shown global warming‐induced advances in start, delays in end, and thus increased lengths of growing season and gross photosynthesis in recent decades. The tradeoffs between seasonal dynamics of two opposing fluxes, CO2 uptake through photosynthesis and release through respiration, determine the influence of the terrestrial ecosystem on the atmospheric CO2 and 13C/12C seasonality. Here, we use four CO2 observation stations in the Northern Hemisphere, namely Alert, La Jolla, Point Barrow, and Mauna Loa Observatory, to determine how changes in vegetation productivity and phenology, respiration, and air temperature affect both the atmospheric CO2 and 13C/12C seasonality. Since the 1960s, the only significant long‐term trend of CO2 and 13C/12C seasonality was observed at the northern most station, Alert, where the spring CO2 drawdown dates advanced by 0.65 ± 0.55 days yr−1, contributing to a nonsignificant increase in length of the CO2 uptake period (0.74 ± 0.67 days yr−1). For Point Barrow station, vegetation phenology changes in well‐watered ecosystems such as the Canadian and western Siberian wetlands contributed the most to 13C/12C seasonality while the CO2 seasonality was primarily linked to nontree vegetation. Our results indicate significant increase in the Northern Hemisphere soil respiration. This means, increased respiration of 13C depleted plant materials cancels out the 12C gain from enhanced vegetation activities during the start and end of growing season. These findings suggest therefore that parallel warming‐induced increases both in photosynthesis and respiration contribute to the long‐term stability of CO2 and 13C/12C seasonality under changing climate and vegetation activity. The summer photosynthesis and the soil respiration in the dormant seasons have become more vigorous which lead to increased peak‐to‐through CO2 amplitude. As the relative magnitude of the increased photosynthesis in summer months is more than the increased respiration in dormant months, we have the increased overall carbon uptake rates in the northern ecosystems.

AbstractRenal transplantation in children with ID is controversial. Acceptability of these children as candidates varies between programs. Limited outcome data in pediatric renal TXP recipients with cognitive impairment diminish their access to TXP. A retrospective chart review was performed of all children who underwent renal transplantation between January 1, 2002 and June 30, 2012 (N=72). Patients were divided into two groups, those with ID prior to transplantation (n=10) and those without (non‐ID; n=62). Graft survival and BPAR episodes were compared between the two groups using Kaplan‐Meier estimates. Graft survival rates at 3 years post‐TXP were 100% in the ID group and 80% in the non‐ID group (P=.13). Rates of BPAR at 3 years post‐TXP were 10% in the ID group and 27% in the non‐ID group (P=.29). Graft survival and acute rejection‐free survival rates are similar between children with ID and those without. Based on midterm outcomes, there is no apparent contraindication to renal transplantation in pediatric patients with ID. Children with ID should be considered as TXP candidates provided that they have an adequate social support network.

AbstractThe Chinese government is considering ways to reconstruct Eucalyptus plantation monocultures in order to improve their ecosystem services. However, the effects of competition or facilitation of Eucalyptus on native species during the reconstruction have not been identified, especially during the formation of novel ecosystems. To better understand these relationships, in this study we tested the effects of competition and facilitation of Eucalyptus on three target species (Schima superba, Michelia macclurei, and Castanopsis fissa), in Eucalyptus plantations with different ages and understory vegetation. The results showed that the survival and growth of S. superba and M. macclurei were not sensitive to plantation age and understory removal treatment. The survival of C. fissa in understory removal was significantly higher and the growth of C. fissa increased gradually with increasing plantation age. The relative neighbor effect (RNE) index for growth indicated that the relationship between Eucalyptus and target species switched from competition to facilitation with an increase in plantation age. A redundancy analysis (RDA) showed that survival was positively correlated with soil water content and soil phosphorus. Growth was positively correlated with soil organic matter and soil nitrogen and negatively correlated with soil bulk density. Our results indicate that plantation age, understory vegetation, and species‐specific traits of target seedlings could change the competition and facilitation roles of Eucalyptus. Higher survival and growth rates indicated that C. fissa was an appropriate species for the reconstruction of mature Eucalyptus plantations and understory removal will benefit the process.
Meaningless vs. Worthwhile Encounters?: Sustaining Social Interactions in Privatized Public Spaces of Manila Shopping Malls
Authors: Reyes Rowena Capulong 
Published: February 2017

Privatized public spaces like modern shopping malls apply various spatial regulations to its mall goers that ultimately, according to scholars of critical tradition, undermines the “social” in socialization during human interactions. This recurring idea is prevalent and proven in a number of developed countries while, on the other hand, research on the same outcome in developing countries such as the Philippines is lacking. Based on local experiences, there is an indication of the possibility of an active associational life within the regulated spaces of the Philippine private shopping mall. This paper tries to determine the circumstances under which spatial governmentality sustains social interaction. Using Robert Yin’s case study method, it delves into the spatial practice of mall users in three shopping malls in the city of Manila. Data are gathered from field observations and interviews with the managers and security officers of the three malls. Purposive mall users can evade the disciplinary, deterrence, and exclusionary techniques of the shopping mall and thus pursue their own social activities and interests in the presence of three facilitators: persons, locales and occasions. The cases involved in this study reveal that efforts to control social activities in mall premises can also generate unintended outcomes, that is, activate social activities.
Efficient Eradication of Established Tumors in Mice with Cationic Liposome-Based Synthetic Long-Peptide Vaccines

Abstract
Therapeutic vaccination with synthetic long peptides (SLP) can be clinically effective against HPV-induced premalignant lesions; however, their efficiency in established malignant lesions leaves room for improvement. Here, we report the high therapeutic potency of cationic liposomes loaded with well-defined tumor-specific SLPs and a TLR3 ligand as adjuvant. The cationic particles, with an average size of 160 nm, could strongly activate functional, antigen-specific CD8+ and CD4+ T cells and induced in vivo cytotoxicity against target cells after intradermal vaccination. At a low dose (1 nmol) of SLP, our liposomal formulations significantly controlled tumor outgrowth in two independent models (melanoma and HPV-induced tumors) and even cured 75%–100% of mice of their large established tumors. Cured mice were fully protected from a second challenge with an otherwise lethal dose of tumor cells, indicating the potential of liposomal SLP in the formulation of powerful vaccines for cancer immunotherapy.

Published: February 2017

Background and Purpose—
Transient ischemic attack (TIA) epidemiology may have changed in recent years as a consequence of improved identification and treatment of vascular risk factors. Our aim was to provide updated information about TIA epidemiology in Italy.

Methods—
Cases of first-ever TIA were ascertained from January 1, 2011, until December 31, 2012, in a population-based prospective registry. All residents in the L’Aquila district with an incident TIA were included and followed up to 2 years after the event. Outcome events were recurrent TIA, nonfatal and fatal stroke, nonfatal and fatal myocardial infarction, and all-cause mortality.

Results—
A total of 210 patients with a TIA according to the traditional time-based definition were included (51.4% women); 151 patients (71.9%) with transient symptoms and negative brain neuroimaging were broadly considered as tissue-based TIA, 29 patients (13.8%) had transient symptoms and evidence of a congruous acute ischemic lesion, and 30 patients (14.3%) had an acute neurovascular syndrome. The crude annual incidence rate for traditional time-based TIA was 35.2 per 100 000 (95% confidence interval, 30.6–40.3) and 28.6 per 100 000 (95% confidence interval, 24.1–33.5) when standardized to the 2011 European population. The incidence peaked in subjects aged ≥85 years, in both sexes. At 2 years, outcome events occurred in 50 patients (23.8%) including 15 patients (7.1%) with nonfatal or fatal strokes.

Conclusions—
Our population-based study found a low annual TIA incidence rate and a fair TIA prognosis confirming the effectiveness of preventive strategies for cardiovascular diseases. We also proved the nonfitting applicability of the tissue-based definition in our district.
