Investigating the existence of a "palaeo-foreshore" zone at Molos beach (Kefalos bay, Paros, Greece).
Authors: Poulos S. , Ghionis G. , Petrakis S. 
Published: January 2017

The present study investigates the existence of a "palaeo-foreshore zone" at Molos beach in or after 1884 A.D., as defined in the Greek legislation (Law 2971/ 19.12.2001). To this end, existing geological and climatological information were gathered, detailed geomorphological mapping was carried out and surficial sediment samples were collected along a shore-normal transect extending from the backshore to the nearshore (subaqueous) zone. In addition, sedimentological /stratigraphical data were obtained from two trenches (1.5 m and 3 m deep) that were excavated on the landward side of the coastal dunes. Topographic maps, aerial photographs and satellite images are used to study the recent changes of the shoreline position. On the basis of the above, it is concluded that the current backshore zone has recently evolved from a shallow lagoonal, to a terrestrial environment. The submerged beach rock formations are at similar water depths (0.3-0.4 m) with those observed in other islands of the Cyclades complex (i.e. Rhenia, Naxos) whose formation has been radio-carbon dated at least 200 years BP, indicating that the 1884 A.D. shoreline was not landward, but approximately 15 m offshore relative to its present position
Ο Ορφέας του σκότους (Στον κινηματογράφο του Ζαν Κοκτό)
Authors: Kolovos Nikos

Lévénement le plus important de la «vie» d' Orphée fut sa descente dans l'Hadès, à laqualle il se résolut, demeuré inconsolable après la mort de sa bien- aimée Eurydice. La «mort» d' Orphée est le second événement extraordinaire de sa vie. Jean Cocteau s'est limité essentiellement à la description du premier événement pour tourner ses films «Orphée» (1950) et «Le Testament d'Orphée» (1959). Pour Cocteau, le cinéma était poétique par excellence, «un véhicule de poésie», selon ses propres termes. Car l'inventif langage audiovisuel lui donnait la possibilité de dépasser la réalité et de se mouvoir librement dans l'irréalité. Cocteau a vu le mythe secondaire mais universel d'Orphée sous deux angles: a) dans son film «Orphée», comme une série d'ombres rayonnantes et une réunion de corps éphémères. Mais certains d'entre eux traversent le temps du monde d' En-Haut tandis que d'autres se meuvent entre celui-ci et le monde d'En-Bas. Un film qui pourrait être lu comme un étrange film noir mais aussi comme un récit chargé de la parole poétique de Cocteau. b) dans son film «Le Testament d'Orphée», comme une possibilité pour Cocteau lui-même de s'incarner en Orphée. En un poète sensible, mélancolique et inquiet errant entre le monde des Enfers et le monde des vivants, prêt à léguer à l'avenir des poètes sa noble et sage expérience. Par ces deux textes filmiques, Cocteau «a usurpé ou s'est approprié» le mythe d'Orphée. Il en a fait un radeau poétique pour façonner la mer d'ombres qui unit les deux univers, celui d'En-Haut et celui d'En-Bas.«Orphée» est à maints égards une version parodique qui transgresse le mythe archétype. «Le Testament d'Orphée» vient en interprétation authentique et en post-scriptum «narcissique» au film précédent. Mais il s'inscrit aussi comme une destruction de la relation excentrique de Cocteau avec le cinéma.

Magnetically Controlled Photovoltaic Diode Structure

Published: January 2017

AbstractWe propose a new integrated device for spintronics application, which is based on a hybrid metal-semiconductor structure. The device consists of a Si-based p-i-n photodetector sandwiched between two layers of a ferromagnetic metal (3d ferromagnet or half-metallic compound). The photocurrent flowing in such a system is shown to depend on its magnetic configuration. This, in turn, allows controlling the device performance by an externally applied magnetic field. We have estimated magnitude of the effect and also determined the role of relevant material parameters.
Interfacial Contributions to Magnetostriction of Ferromagnetic Layers for Magnetoresistive Sensors
Authors: Singleton E.W. , Duxstad K.J. 
Published: January 2017

AbstractWe have experimentally measured magnetostriction of thin CoFe layers when deposited with various seed and capping layers. Seed and capping layers were chosen to be materials that may be used in spin-valve (SV) type structures. Materials deposited adjacent to the magnetic layer include Cu, Ta and TaN. The experimental results are interpreted using a model that allows separation of bulk and interface contributions to the measured magnetostriction [1].Results show a clear interfacial contribution that is dependent upon the material at the interface of the magnetic layer. The results demonstrate that surface contributions to the magnetostriction dominate as layer thickness decreases.
Texture and Resistivity of Cu and Dilute Cu Alloy Films

Published: January 2017

AbstractAnnealing of dilute binary Cu(Ti), Cu(In), Cu(Al), Cu(Sn), Cu(Mg), Cu(Nb), Cu(B), Cu(Co) and Cu(Ag) alloy films resulted in the strongest <111> fiber texture for Cu(Ti) and the lowest resistivity for Cu(Ag). The behavior of the alloy films was compared and contrasted with that for a pure evaporated Cu film. Electron beam evaporated films with compositions in the range of 2.0-4.2 at% and thicknesses in the range of 420-560 nm were annealed at 400°C for 5 hours. Two different approaches were used to derive volume fractions of texture components, namely fiber plots and orientation distributions. It is argued that for polytextured films such as the copper alloys studied here, orientation distributions derived from pole figures provide the most reliable basis for quantitative characterization.
Effect of Texture on Hillock Formation in Aluminum Films
Authors: Muppidi T. , Kusama Y. , Field D.P. 
Published: January 2017

AbstractStress voiding describes a phenomenon in thin interconnect lines where hillocks and voids are formed during thermal cycling due to the stresses caused by the difference in the thermal expansion coefficients of metal used in the interconnect lines and the substrate material. The effect of texture on stress voiding in aluminum interconnects is investigated using orientation imaging microscopy (OIM© ) and scanning electron microscopy. Aluminum films were deposited by PVD deposition onto sublayers of Ti and Ti plus TiN and were analyzed for crystallographic texture and grain boundary structure using OIM©. These films were later annealed at 400°C for 1 hour and cooled. The specimens were examined for the presence of hillocks and voids using a scanning electron microscope. The results show strongly textured (111) films are more resistant to hillock and void formation.
The Initial Growth Stages and Crystallization Mechanism of Bi-based films
Authors: Kononenko Oleg V. , Andreeva Alexandra V. , Il'in Alexandr I. 
Published: January 2017

AbstractThe present work deals with investigation of the initial stages of growth of (Bi, Bi-Sb) films deposited by the methods of different degrees of nonequilibrium, such as thermal evaporation (TE) and self-ion assisted deposition (SIAD). The comparative analysis of growth mechanisms and film island evolution (faceting and coalescence) was carried out depending on the type (crystalline, amorphous) and temperature of substrate, evaporation rate, film composition, etc. Ion bombardment during deposition leads to films of higher density and reduced porosity, and greater stability than those deposited without bombardment. As compared with the pure Bi films the facetted island morphology of the SIAD Bi–Sb (20%) films is not so clear. This is explained by partial realization of the coalescence process by the liquid fluidity mechanism. At all substrate temperatures the grain orientation (111) R is more pronounced for SIAD films than for the TE films.

Objective: The aim of this study was to evaluate a technique for the surgical repositioning of the premaxilla using a minimally invasive endonasal approach. Design: Retrospective review of clinical records. Setting: Tertiary care, University Hospital, pediatric maxillofacial surgery unit. Patients: Twenty-one patients (12 boys and 9 girls), ages ranging from 6 to 21 years, with BCLP+A and premaxillary malposition (PM). Interventions: Surgical repositioning of the premaxilla (SRP) using a minimally invasive endonasal approach, from November 2007 to November 2015. Main outcome measures: Achieving maxillary arch alignment and premaxillary stability was defined as treatment success. Intraoperative and postoperative complications were also recorded. Results: In all cases (100%), the treatment was successful either at first surgery or after reoperation. Two patients (9.5%) were reoperated-one due to premaxillary instability and one due to PM relapse. There were no perioperative complications. Conclusions: SRP using a minimally invasive endonasal approach is a safe and effective technique that levels and aligns the maxillary arch in preparation for SABG, which minimizes the risk of wound infection and premaxillary vascular compromise. The endonasal approach improves tissue quality of the mucoperiosteal flaps when performing the SABG procedure. Further prospective studies are needed to elucidate the best protocols and techniques for the management of PM in patients with BCLP+ A.

Authors: Bathalapalli Jagan Mohan Reddy , Varma Gunturi Surya Ramachandra , Rao V. Ram Mohan , P. Mythili 
Published: January 2017

Background: Incisional hernia occurs in 5-11% of patients subjected to abdominal operations. Laparoscopic hernia repair has revolutionized the treatment of incisional hernia by reducing the morbidity and improved post-operative outcomes. The objectives of this study were to compare open incisional hernia repair with laparoscopic incisional hernia repair in our patient population with respect to Operating time, post-operative complications, post-operative recovery, duration of analgesic administration, and cosmetic results.Methods: This is a prospective study of Forty patients who were admitted at Osmania General Hospital, Hyderabad, Telangana, India with a clinical diagnosis of incisional hernia, 20 patients in each group (open and laparoscopic).Results: Both the study groups were comparable in terms of patient characteristics. The duration of laparoscopic repair was significantly more when compared to open repair (mean time 133.75 mins versus 85.8 min respectively). Analgesic requirement, wound infection rate and complication rate were higher in open group. The laparoscopic patients tolerated oral feeds earlier compared to open patients. The duration of hospital stay was significantly longer for open group than for laparoscopic group (mean 9.6 days versus 6.4 days respectively). The cosmetic end result was better in laparoscopic patients.Conclusions: Though ours is a small study, with the benefits of laparoscopy it will be prudent to recommend laparoscopic repair as the first line of management for incisional hernia where the facilities and trained expertise were available. However, there is still a role for traditional open approach in patients who have a specific contraindication to laparoscopic repair or any additional procedures that are not amenable for laparoscopy.

<p class="Default">The purpose of this study to determine the quality of chicken carcasses were given rations containing omega-3 fish oil. This study uses a Completely Randomized Design (CRD) with 5 treatments and 5 replications, each replication 4 free-range chickens. If treatment showed significance, then continued with Duncan's Multiple Range Test. The treatment consisted of fish oil that is R0 = 0% (basal feed), R1 = (basal feed 98,5%+1,5% MI), R2 = (basal feed 98%+2% MI), R3 = (basal feed 97,5%+2,5% MI), R4 = (basal feed 97%+3% MI). The variables measured were the weight of the chest (g), the weight of the thigh (g), the weight back (g) and wing weight (g). The results showed that the use of fish oil in the diet provides highly significant effect (P&lt;0,01) in the weight of the chest and thigh weights, but the effect is not significant (P&gt;0,05) to the weights and the weight of the wing backs. The conclusion that the quality of carcass weights comprised chest, thigh weight, the weight of the back and the weight of chicken wings increased the ration of fish oil to the level of 3%.</p><p> </p><p>Keywords: carcass, chicken, fish oil.</p>
Technology Update: Encapsulated ESP Handles Multiphase Flows To Extend Run Life and Boost Oil Recovery
Authors: Nichols Jonathan , Holland Nathan 
Published: January 2017

Technology Update
Electrical submersible pump (ESP) systems are critical to achieving the maximum production rates and reservoir pressure drawdown that improve ultimate recovery. But when gas pockets enter the wellbore and cause system interruptions, the effectiveness of a traditional ESP can be undermined.
Gas-handling capability is one of the most complex and challenging issues in artificial lift. Production in unconventional wells varies significantly, depending on the evolution of the reservoir. In a typical scenario, the well begins producing with high liquid rates and some gas. Over a period of a few months, oil production rates fall and gas production rises.
While many wells can produce with small quantities of gas, the presence of large gas volumes precludes the use of conventional pumping equipment. The gas-handling challenges are exacerbated by the long horizontals and multiphase flow of oil and gas that are common in unconventional oil plays.
Most horizontal wells are not perfectly horizontal. The wells’ lateral portions have undulations that cause the accumulation of water in the low spots and gas in the high spots. During the production phase in unconventional plays, higher levels of natural gas are usually released from the pay zone as reservoir pressure depletes. This gas typically enters the horizontal wellbore and accumulates in the high side of the lateral, creating large gas slugs that cause low-flow or no-flow conditions in an ESP system as they move up the wellbore. The resulting cycling and gas-lock conditions affect system reliability, which can interrupt production and limit ultimate reserves recovery.
In challenging downhole conditions, operators often choose to install an ESP system below the perforations. This scenario is particularly useful in wells with high gas content in the fluid stream and in highly productive wells, where operators want to maximize the pressure drawdown to release additional reserves from the reservoir. Placing the ESP below the perforations separates the gas from the fluid, eliminating issues associated with gas entering the ESP.
However, reliability becomes a concern because fluid does not flow past the motor at the appropriate velocity to ensure motor cooling. To overcome this issue, the ESP motor can be encased in a shroud, but using a shroud can limit the size of the ESP system and, therefore, production rates.
Distributed Acoustic Sensing for Downhole Production and Injection Profiling
Authors: Carpenter Chris 
Published: January 2017

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 175211, “Latest Developments Using Fiber-Optic-Based Well Surveillance Such as Distributed Acoustic Sensing for Downhole Production and Injection Profiling,” by Juun van der Horst and Peter in ’t Panhuis, Shell; Nabil Al-Bulushi, Saudi Aramco; Greg Deitrick, Daria Mustafina, Gijs Hemink, Lex Groen, and Hans Potters, Shell; and Rifaat Mjeni, Kamran Awan, Salma Rajhi, and Goos Bakker, Petroleum Development Oman, prepared for the 2015 SPE Kuwait Oil and Gas Show and Conference, Mishref, Kuwait, 11–14 October. The paper has not been peer reviewed.
In the past decade, fiber-optic (FO) -based sensing has opened up opportunities for in-well reservoir surveillance in the oil and gas industry. Distributed-temperature sensing (DTS) has been used in applications such as steam-front monitoring in thermal enhanced oil recovery and injection-conformance monitoring in waterflood projects. FO-based pressure gauges are deployed commonly. Significant progress also has been made in maturing other new FO-based surveillance methods such as distributed acoustic sensing (DAS). In this paper, the authors present a recent example of single-phase-flow profiling with DAS.
Introduction
FO-based surveillance allows for a complete, instantaneous data set from the top to the bottom of the well vs. traditional logging methods that can consume many hours to collect a single trace of a limited interval of the well. A recent development is the use of DAS, which converts a standard fiber deployed over an entire wellbore into a permanent array of microphones. DAS has proved its utility for monitoring of hydraulic-fracturing (HF) operations and for acquisition of vertical-seismic- profile (VSP) surveys and microseismic. A third promising application under development is that of measuring downhole production or injection-flow performance, where DAS can replace the conventional production-logging-tool (PLT) survey for a number of flow regimes and well types.
Because the same FO cable can be used for different measurements by connecting the appropriate interrogation unit to the cable, it is, for instance, possible to use DAS for first monitoring the HF treatment during the initial well completion, followed by time-lapse production profiling surveys to assess the (change in) flow behavior for optimizing well inflow/outflow performance or improving the completion design of future producers.
Deepwater Projects
Authors: Iversen Morten 
Published: January 2017

The high costs surrounding deepwater developments and the low price of oil are a challenging combination for operators and service companies today.
Considering transportation, services, qualifications, permitting, and infrastructure costs, capital-expenditure costs for deepwater developments are much higher than they are for onshore developments. Similarly, operating in remote locations, where risk must be low and safety and preparedness must be high, operating-expenditure costs are also much higher for deepwater projects than they are for those onshore.
Industry has recognized that, even at USD 100/bbl, the costs of some deepwater developments were not sustainable, and, when it comes to USD 30/bbl oil, it is obvious that the operator cannot justify this capital and operating cost.
During the first decade of the 2000s, escalating oil and gas prices were the rising tide that lifted all boats. It essentially bailed out many floundering projects, masked poor project performance, and bred profligacy and complacency.
In addition, operators were able to justify designing operations that were more flexible and could respond to a greater number of scenarios. However, this resulted in complex designs, which involved more engineering and greater costs.
However, in the current cost environment, the operator must now work with the service companies to discuss what acceptable specifications are. If deepwater operations are to survive going forward, the luxury of unnecessary customization of facilities and individual company specifications of components must cease; industry needs to develop a more-cost-effective “good enough” mind set.
By simplifying, standardizing, and industrializing deepwater technologies, 25–30% reductions in lead time and costs are possible, but there are limits to how much this can save.
The resources we are developing no longer come from massive fields, which limits the economic and cost-saving potentials. Second, the industry cannot create a commodity industry like the automotive industry.
These issues may be overcome with the willingness of the deepwater industry to continue investing in technology developments, and, in particular, technology and constant innovation are what will bring us acceptable economic profitability, which will allow us to continue deepwater development. JPT
