Synthesis and luminescence study of Zn3V2O8: Bi3+ yellow phosphor for solar spectral conversion
Authors: Zhang Xinguo , Guan Anxiang , Zhou Liya , Gong Menglian
Published: February 2017

A yellow phosphor Zn3V2O8: Bi3+ was synthesized by solid‐state method. It can efficiently absorb UV photons of 250‐400 nm, and convert into strong yellow emission with maximum at 550 nm, which can be absorbed by dye‐sensitized solar cells (DSSCs). VO4→Bi3+ energy transfer is discussed. The critical Bi3+ concentration is 0.04 with critical distance of 13.25 Å. The CIE coordinates of Zn3V2O8: Bi3+ are (0.421, 0.518). Zn3V2O8: Bi3+ phosphor exhibits good thermal stability with T1/2=150°C. The results indicate that Zn3V2O8: Bi3+ phosphor is a promising UV‐absorbing spectral converter to enhance power conversion efficiency and photochemical stability of DSSCs.

ABSTRACT

BACKGROUND

Limiting food and beverage marketing to children is a promising approach to influence children's nutrition behavior. School‐based marketing influences nutrition behavior and studies have consistently found marketing for nonnutritious foods and beverages in schools. No studies have examined the resources necessary to align school marketing environments with federal school nutrition standards. The purpose of this study was to determine how to improve school marketing environments so that they align with new federal competitive food nutrition standards.

METHODS

We assessed food marketing environments in 3 Portland, Maine schools using the Food and Beverage Marketing Survey (FBMS) and provided technical assistance to bring their marketing environments into conformity with the federal competitive food regulations, tracking resources and strategies for marketing removal.

RESULTS

Noncompliant marketing was significantly reduced pre‐ to postintervention. Intervention strategies were facilitated by the School Health Coordinator and school‐based wellness teams.

CONCLUSIONS

Low monetary resources were required to remove marketing not compliant with federal nutrition standards for foods sold in schools. Several key challenges remain to sustain efforts. This study provides timely information for policymakers to support crafting policies that address the realities of school nutrition environments and universal enforcement challenges.

Authors: Mohd Ali Nor Muhainiah , Noor Azhuan Nur Azura , Sarmin Nor Haniza , Johar Farhana
Published: February 2017

This research is focused on two types of finite abelian groups which are the group of integers under addition modulo , and the group of integers under multiplication modulo , where  is any positive integer at most 200. The computations of some properties of the group including the order of the group, the order and inverse of each element, the cyclic subgroups, the generators of the group, and the lattice diagrams get more complicated and time consuming as n increases. Therefore, a special program is needed in the computation of these properties. Thus in this research, a program has been developed by using Microsoft Visual C++ Programming. This program enables the user to enter any positive integer at most 200 to generate answers for the properties of the groups.
What Role Does Continuance Commitment Play In The Relationship Between Affective Commitment And Organizational Citizenship Behaviour? Case Study Somali Telecommunication Industry Players
Authors: Osman Osman H. , Sarip Azlineer , Mohd Arif Lily Suriani
Published: February 2017

The purpose of the study is to investigate the role of continuance commitment in the relationship between affective commitment and organizational citizenship behaviour (OCB) among the employees of telecommunication industry players in Mogadishu, Somalia. A total of 92 lower managers (supervisors) from three different telecommunication players were involved in this study. The instrument used in the study for affective and continuance commitment was adopted from Natalie J. Allen and John P. Meyer (1990), and for OCB was adopted from Philip M. Podsakoff , Scott B. MacKenzie, Robert H. Moorman, and Richard Fetter (1990). This  quantitative survey method employed stratified random sampling technique. Employees’ attitudes and behaviours were tested for correlation and regression analysis. The findings indicated that there are positive and significant relationship between employees’ affective commitment, continuance commitment and OCB. The highest correlations towards employees’ citizenship behaviour is the mediation role of continuance commitment (r=.362, p< .05), then affective commitment (r=.287, p< .05), followed by the relationship between affective commitment and continuance commitment (r=.249, p< .05), whilst continuance commitment shows the weakest relationship on OCB (r=.144, p< .05). The regression model indicates a predictive significance by employees’ behaviours; thus, the findings support the conclusion that the selected behaviours are predictors of telecommunication industries employees’ OCB. This study revealed the importances of organizational citizenship behaviour (OCB), affective commitment and continuance commitment among the telecommunication industries employees’in Mogadishu, Somalia. These findings also have implications for telecommunication industries and managers to reflect and extend employees’ organizational citizenship behavior (OCB).
A modal approach to piano soundboard vibroacoustic behavior
Authors: Trévisan Benjamin , Ege Kerem , Laulagnet Bernard
Published: February 2017

This paper presents an analytical method for modeling the vibro-acoustic behavior of ribbed non-rectangular orthotropic clamped plates. To do this, the non-rectangular plate is embedded in an extended rectangular simply supported plate on which a spring distribution is added, blocking the extended part of the surface, and allowing the description of any inner surface shapes. The acoustical radiation of the embedded plate is ensured using the radiation impedances of the extended rectangular simply supported plate. This method is applied to an upright piano soundboard: a non-rectangular orthotropic plate ribbed in both directions by several straight stiffeners. A modal decomposition is adopted on the basis of the rectangular extended simply supported plate modes, making it possible to calculate the modes of a piano soundboard in the frequency range [0;3000] Hz, showing the different associated mode families. Likewise, the acoustical radiation is calculated using the radiation impedances of a simply supported baffled plate, demonstrating the influence of the string coupling point positions on the acoustic radiated power. The paper ends with the introduction of indicators taking into account spatial and spectral variations of the excitation depending on the notes, which add to the accuracy of the study from the musical standpoint. A parametrical study, which includes several variations of soundboard design, highlights the complexity of rendering high-pitched notes homogeneous.
Interactions between climate and landscape drive Holocene ecological change in a High Arctic lake on Somerset Island, Nunavut, Canada
Authors: Paull Tara M. , Finkelstein Sarah A. , Gajewski Konrad
Published: February 2017

This study presents a diatom-based analysis of the post-glacial Holocene environmental history at Lake RS29 on Somerset Island in the Canadian High Arctic. Earliest post-glacial diatom assemblages (10 200–10 000 cal yr BP) consisted mainly of small, benthic fragilarioid taxa. Poor diatom preservation in the early Holocene (~10 000–6200 cal yr BP) is associated with warm conditions, as determined by pollen data from the same core and other paleoclimate estimates from the region. Analysis of this and other sites from across the Canadian Arctic suggest that zones of poor diatom preservation or diatom absence in lake sediment records may be associated with warm conditions. After 6200 cal yr BP, acidophilic assemblages consisting of Aulacoseira spp. and a suite of periphytic taxa indicate acidification since the mid-Holocene. During this time period, cooling causing changes in lake ice phenology was likely a major driver of the reconstructed mid-Holocene pH decline. Watershed processes, including reduced fluxes of base cations as the rate of sediment accumulation slowed, may also be contributors to long-term shifts in lake water pH and associated changes in diatom assemblages. The uppermost sediments in the Lake RS29 record were characterized by abrupt declines in Aulacoseira alpigena and increases in benthic diatom taxa Cyclotella sensu lato, suggesting an increase in lake water pH and longer ice-free seasons.

Published: February 2017

The spatial scales at which animals make behavioral trade-offs is assumed to relate to the scales at which factors most limiting resources and increasing mortality risk occur. We used global positioning system collar locations of 29 reproductive-age female black bears (Ursus americanus Pallas, 1780) in three states to assess resource selection relative to bear population-specific density, an index of vegetation productivity, riparian corridors, or two road classes of and within home ranges during spring–summer of 2009–2013. Female resource selection was best explained by functional responses to vegetation productivity across nearly all populations and spatial scales, which appeared to be influenced by variation in bear density (i.e., intraspecific competition). Behavioral trade-offs were greatest at the landscape scale, but except for vegetation productivity, were consistent for populations across spatial scales. Females across populations selected locations nearer to tertiary roads, but females in Michigan and Mississippi selected main roads and avoided riparian corridors, whereas females in Missouri did the opposite, suggesting population-level trade-offs between resource (e.g., food) acquisition and mortality risks (e.g., vehicle collisions). Our study emphasizes that female bear population-level resource selection can be influenced by multiple spatially dependent factors, and that scale-dependent functional behavior should be identified for management of bears across their range.
Spatial distribution and quantum trajectory control of the molecular harmonic spectra
Authors: Liu Hang , Castle Rich-Samuel , Li Wenliang , Feng Liqiang
Published: February 2017

Spatial distribution and quantum trajectory control of the molecular harmonic spectra from H[Formula: see text] are theoretically investigated through the combination of a few-cycle 800[Formula: see text]nm pulse and a half-cycle pulse. Results show that by properly adding the half-cycle pulse, the harmonic cutoffs from the recombination process are extended, and the harmonic intensities from the positive-[Formula: see text] direction are suppressed. Moreover, as the internuclear distance increased, the modulations on the harmonic spectra are reduced. The time-dependent wave function and the time-frequency analyses of the harmonic spectra are shown to explain the above physical mechanism. Further, by adding the laser pulse to the bowtie-shaped gold nanostructure separated by an air gap [Formula: see text][Formula: see text]nm, much higher harmonic cutoff order can be obtained in the positive-[Formula: see text] region. Finally, two isolated attosecond pulses with the full width at half maximum of 34as and 31as are obtained.

Published: February 2017

A dairy cattle farm in Liuying, Tainan on 29 June 2015. The two-month-old calves in the farm were found with opisthotonus, lameness, paralysis and ataxia. The morbidity is approximately 1.1% and the mortality is 0%. In gross lesions, flat gyri, shallow sulci and meningeal vascular engorgement were seen. Histopathological examinations revealed non-suppurative lymphohistocytic encephalomyelitis and pachymeningitis with hemorrhage, lymphohistocytic perivascular cuffing, microgliosis and demyelination. Nucleic acid was extracted from Spinal cord, then amplified by reverse transcriptase polymerase chain reaction. A 709-base pair amplification product of S segments was detected and showed 99.9% homology to Akabane virus by nucleotide sequencing. Thus, according to the laboratory examination and analysis of the results, this case diagnosed with Akabane disease in dairy cattle.

Hoop-algebra is a naturally ordered commutative residuated integral monoids, which is introduced by B. Bosbach in Refs. 7 and 8. Now, in this paper, by considering the notion of hyper hoop-algebra, we find a condition to obtain a hoop from a finite bounded hyper hoop-algebra. Then we investigate the relations among hyper hoop-algebras and some of the other logical (hyper) algebras such as (hyper) [Formula: see text]-algebras, hyper [Formula: see text]-algebras, hyper [Formula: see text]-algebras, hyper [Formula: see text]-algebras and hyper [Formula: see text]-algebras.
Patterns of primes in Chebotarev sets

Published: February 2017

The work of Green and Tao shows that there are infinitely many arbitrarily long arithmetic progressions of primes. Recently, Maynard and Tao independently proved that for any [Formula: see text], there exists [Formula: see text] (depending on [Formula: see text]) so that for any admissible set [Formula: see text], there are infinitely many [Formula: see text] such that at least [Formula: see text] of [Formula: see text] are prime. We obtain a common generalization of both these results for primes satisfying Chebotarev conditions. We also give an improvement of the known bound for gaps between primes in any given Chebotarev set.

Upregulation of fatty acid amide hydrolase in the dorsal periaqueductal gray is associated with neuropathic pain and reduced heart rate in rats
Authors: Dean Caron , Hillard Cecilia J. , Seagard Jeanne L. , Hopp Francis A. , Hogan Quinn H.
Published: February 2017

Nerve damage can induce a heightened pain response to noxious stimulation, which is termed hyperalgesia. Pain itself acts as a stressor, initiating autonomic and sensory effects through the dorsal periaqueductal gray (dPAG) to induce both sympathoexcitation and analgesia, which prior studies have shown to be affected by endocannabinoid signaling. The present study addressed the hypothesis that neuropathic pain disrupts autonomic and analgesic regulation by endocannabinoid signaling in the dPAG. Endocannabinoid contents, transcript levels of endocannabinoid signaling components, and catabolic enzyme activity were analyzed in the dPAG of rats at 21 days after painful nerve injury. The responses to two nerve injury models were similar, with two-thirds of animals developing hyperalgesia that was maintained throughout the postinjury period, whereas no sustained change in sensory function was observed in the remaining rats. Anandamide content was lower in the dPAG of rats that developed sustained hyperalgesia, and activity of the catabolic enzyme fatty acid amide hydrolase (FAAH) was higher. Intensity of hyperalgesia was correlated to transcript levels of FAAH and negatively correlated to heart rate and sympathovagal balance. These data suggest that maladaptive endocannabinoid signaling in the dPAG after nerve injury could contribute to chronic neuropathic pain and associated autonomic dysregulation. This study demonstrates that reduced anandamide content and upregulation of FAAH in the dPAG are associated with hyperalgesia and reduced heart rate sustained weeks after nerve injury. These data provide support for the evaluation of FAAH inhibitors for the treatment of chronic neuropathic pain.

Person detection and tracking in crowd is a challenging task. We detect the head region and based on this head region we can detect people from crowd. Individual object detection has been improved significantly in recent times but the crowd detection and tracking contains some challenges. Crowd analysis is a highly focused area for law enforcement, urban engineering and traffic management.  There are a lot of incident occurred in crowd area during some fabulous event. In this research low resolution and verities of image orientation is a key factor as well as overlapping person images in crowd misguided the system. An enhanced system of interest point detection based on gradient orientation information as well as improved feature extraction HOG is used for identifying the human head or face from crowd. We have analyzed different types of images in different varieties and found accuracy 88-90%. In a number of applications, such as document analysis and some industrial machine vision tasks, binary images can be used as the input to algorithms that perform useful tasks. These algorithms can handle tasks ranging from very simple counting tasks to much more complex recognition, localization, and inspection tasks. Thus by studying binary image analysis before going on to gray-tone and color images, one can gain insight into the entire image analysis process.

Η απουσία του νόμιμου ηγεμόνα, η διεκδίκηση της εξουσίας του και η παρεμπόδιση της επιστροφής του ίδιου ή του διαδόχου του είναι θέματα κοινά στο Χρονικό τον Μορέως, τον Αυθέντη τον Μορέως, τον Ιβανόη και την Οδύσσεια. Εκδοχές της Οδύσσειας λειτουργούν ως διακείμενα στον Ιβανόη και τον Αυθέντη τον Μορέως αλλά και στο ταξίδι που κάνει ο Ραγκαβής κατά την άφιξη του στην Ελλάδα το 1829, όπως περιγράφεται στα Απομνημονεύματα του. Αντίθετα προς την επικρατούσα άποψη, ο Ραγκαβής πέτυχε να δημιουργήσει στον Αυθέντη τον Μορέως μια σφιχτά οργανωμένη πλοκή με πρωταγωνιστή τον Βιλλαρδουίνο, ο οποίος φέρνει σε πέρας τρία σχέδια: την εξαπάτηση του Ροβέρτου και την κατάκτηση της Αυθεντίας· τον γάμο του γιου του με την Αγνή Κουρτεναίη, ανιψιά του Λατίνου αυτοκράτορα της Κωνσταντινούπολης, που εξυπηρετεί μακροπρόθεσμες φιλοδοξίες του (στο Χρονικό ο γάμος γίνεται μετά τον θάνατο του Βιλλαρδουίνου)· και, τέλος, τον εντοπισμό και την παράδοση των Ελλήνων επαναστατών και την αναγνώριση του από αυτούς ως Αυθέντη του Μορέως. Η «μεγάλη θήρα» στα βουνά της Ανδραβίδας, με την οποία ολοκληρώνεται ο Αυθέντης τον Μορέως, αποτελεί το πολιτικό ανάλογο των αιματηρών επιχειρήσεων στον Ιβανόη και την Οδύσσεια και το κορυφαίο επίτευγμα του Βιλλαρδουίνου. Η τελική άρνηση του Έλληνα πρωταγωνιστή Λέοντα Χαμάρετου να συμφιλιωθεί με τη φράγκικη εξουσία προεξαγγέλλεται μέσα από τη στάση του στην κονταρομαχία και εκφράζεται μέσα από το όνομα του, όπου συγκλίνουν στοιχεία από τον Σπαρτιάτη Λεωνίδα, τον «Μέλανα Ιππότη» Ριχάρδο τον Λεοντόκαρδο και τον ομηρικό λέοντα, που σπρώχνεται από την ορμή να σκοτώσει ή να πεθάνει, αντί να ντροπιαστεί. Η περιγραφή μιας κρίσης στον ιστορικό βίο και η υπέρβαση της καθιστά τον Αυθέντη του Μορέως το πρώτο και μοναδικό ιστορικό μυθιστόρημα που γράφεται με τους όρους του Ουόλτερ Σκοτ.

Published: February 2017

Currently, machine-building enterprises are increasingly using new composite materials for the production of parts, accessories and repair. One such material is a metallopolymeric composite structure with an aluminum filler. In general, it is an epoxy-dienoic filled with an aluminum matrix excipient. Owing to its flow properties in the uncured state, and hardness and heat resistance when cured, the material is increasingly used in the production. Previous studies have shown the use of metal-polymer material as the material forming the mold parts, as this significantly reduces the cost of equipment for molding plastics. Unlike steel machining modes metallopolymers insufficiently studied, because the material is new, and as yet only finds its field of application. However, in the manufacture of it forming tooling molds required to appoint such process steps and processing modes, which will provide the required dimensional accuracy and surface roughness detail. For a given parameter surface roughness of a metallopolymeric in the processing of grinding was found model of the surface roughness of the parameter rate table movement and the depth of cut.

Published: February 2017

We use novel data on individual activity in a sports betting market to study the effect of past performance sequences on individual behavior in a real market. The idiosyncratic nature of risk in this market and the revelation of assets’ true terminal values enables us to disentangle whether behavior is caused by sentiment or by superior information about market mispricings and to cleanly test two prominent theories of momentum and reversals—the regime-shifting model of Barberis et al. [Barberis N, Shleifer A, Vishny R (1998) A model of investor sentiment. J. Financial Econom. 49(3):307–343] and the gambler’s/hot-hand fallacy model of Rabin [Rabin M (2002) Inference by believers in the law of small numbers. Quart. J. Econom. 117(3):775–816]. Furthermore, our long panel enables us to study the prevalence across individuals of each type of behavior. We find that (i) three-quarters of individuals exhibit trend-chasing behavior, (ii) seven times as many individuals exhibit behavior consistent with Barberis et al. (1998) as exhibit behavior consistent with Rabin (2002), and (iii) no individuals earn superior returns from momentum trading.

Published: February 2017

Gnathostomiasis is a prevalent zoonosis in humans in some regions of the world. The genus Gnathostoma is considered an accidental parasite for humans; G. binucleatum is the endemic species in Nayarit, Mexico. This work was designed to determine the proteolytic activity of the excretory-secretory products (ESP) of advanced third-stage larvae (ADVL3) of Gnathostoma binucleatum against human fibronectin and antibodies from human and sheep. Our findings showed protease activity against human fibronectin as well as sheep and human gamma globulins of the ESP at molecular weights of 80 and 56 kDa. The proteases found in the ESP of G. binucleatum are thus candidate molecules for consideration as pathogenic elements, owing to the fact that they destroy proteins of the host tissue, which probably allows them to migrate through those tissues and degrade molecules involved in the humoral immune response.
Effect of body composition on walking economy
Authors: Maciejczyk Marcin , Wiecek Magdalena , Szymura Jadwiga , Szygula Zbigniew
Published: February 2017

Purpose

The aim of the study was to evaluate walking economy and physiological responses at two walking speeds in males with similar absolute body mass but different body composition.

Methods

The study involved 22 young men with similar absolute body mass, BMI, aerobic performance, calf and thigh circumference. The participants differed in body composition: body fat (HBF group) and lean body mass (HLBM group). In the graded test, maximal oxygen uptake (VO2max) and maximal heart rate were measured. Walking economy was evaluated during two walks performed at two different speeds (4.8 and 6.0 km h–1).

Results

The VO2max was similar in both groups, as were the physiological responses during slow walking. The absolute oxygen uptake or oxygen uptake relative to body mass did not significantly differentiate the studied groups. The only indicator significantly differentiating the two groups was oxygen uptake relative to LBM.

Conclusions

Body composition does not significantly affect walking economy at low speed, while during brisk walking, the economy is better in the HLBM vs. HBF group, provided that walking economy is presented as oxygen uptake relative to LBM. For this reason, we recommend this manner of oxygen uptake normalization in the evaluation of walking economy.
Vision Impossible? Some Aspects of the Current Russian Debates about the Military Sciences
Authors: Eklund Niklas
Published: February 2017

In 21stcentury military theory and doctrine, it is common to subdivide military capability into conceptual, physical and moral components. At least in theory, it follows that conceptual capability should be regarded as the crucial link between the physical and moral capabilities of a given military actor, as it concerns the ability of the actor to operationalise ideas about how to conduct modem warfare. Conceptual military capability can thus be defined as the sum of an actor’s military know­how, scientific capacity and doctrine, which defines the expected ability of an actor to uphold an efficient language of military action, distribution and command.

Watching Handball Transmissions.
Authors: Frandsen Kirsten
Published: February 2017

The current article presents a qualitative study of Danish television viewer’s reception of Danish handball transmissions. The overall aim of the study has been to contribute to a more nuanced understanding of televised sport as a specific kind of television entertainment. The analysis shows that, due to the dramaturgic structure of handball transmissions, viewers consider such transmissions particularly reliable and effective sources of entertainment. The transmissions’ entertainment value derives from their specific ability to give the viewers a complex experience of feeling autonomous and competent when mastering the game and in relation to others. The study shows that entertainment concerns both affective involvement and identity formation, as social and cultural meaning seem to be at the root of involvement. Even though both men and women find great joy in the transmissions, their viewing is embedded in quite diverse patterns regarding additional media use. This points to gendered differences regarding how the entertaining experience is basically received and the qualities sought and pursued in the transmissions.

Krisis perikanan merupakan akibat langsung penangkapan yang berlebihan pada sumber daya perikanan, yang antara lain disebabkan oleh teknologi penangkapan modern. Kini kemungkinan terjadi overfishing karena teknologi telah membuat armada penangkapan lebih mudah menuju ke lokasi gerombolanikan besar. Overfishing terjadi ketika suatu jenis ikan diambil lebih cepat dibanding dengan pembiakan stok spesies tersebut untuk menghasilkan penggantinya. Pada perikanan pukat cincin semi industri di Laut Jawa, paling sedikitnya telah terjadi economic overfishing, biological overfishing, dan Malthusian overfishing, di mana biaya ekonomi penangkapan yang mahal untuk hasil sedikit, dan nelayan mengorbankan biaya sosial dengan meninggalkan keluarga semakin lama akibat sulit mencari gerombolan ikan.Supposedly fisheries crisis is a direct result of the severe over harvesting of fisheries resources brought about among other by modern fishing technologies. Overfishing is possible today because technology has made it easier to locate large schools of fish and direct fishing fleets to those locations. Overfishing occurswhen a species is taken more rapidly than the breeding stock of that species can generate replacements. In the purse seiners semi industry fisheries in the Java Sea, at least there have been economic overfishing, biological overfishing, and Malthusian overfishing, where the economic cost of catching a very high price for a bit, and fishermen have to sacrifice the social cost of leaving the family longer because they are hard to find the fish schooling.

     Islamic law agreed with most modern laws on the seriousness of money laundering crimes, including Algerian law and Indonesia, despite the differences in regard to the methods which these crimes because of the different banking systems from one country to another on the one hand, because of the possibilities available to money launderers on the other.

      This led to the need to pay special attention by the Algerian law and Indonesia in order to effectively provide for these modern criminal phenomena, it has resorted to the imposition of strict controls to combat the phenomenon is mostly derived from the provisions of Islamic Sharia.

      Although the procedures and mechanisms that came in the Islamic Sharia and stipulated in the fight against money laundering in Algeria, Indonesia law, but many obstacles stand in the way without effective control of this crime along the lines of the principle of banking secrecy, which is an obstacle, often without disclosure of relevant financial transactions money laundering offenses.
Technology Focus: EOR Performance and Modeling

Since the last time I wrote for this feature, enhanced-oil-recovery (EOR) activities around the world have been steadily increasing, meaning that the unusual crises our industry has been going through did not kill EOR. Instead, activities have expanded. For sure, current conditions have had some effect on how we see EOR, and, amazingly, with few exceptions, it has been positive. Current conditions have made most companies decide to optimize performance of their existing assets, and EOR is a key part of that. After all, optimizing is an ordinary ingredient of cost control. It is also worth adding that unconventional oil, which, for many, was the reason for the current crisis, is a big reason for the expansion of EOR. The unconventional producers are very keen on increasing recovery from their assets. Therefore, while enhancements on drilling and hydraulic fracturing will continue, it is expected that the next big wave will start when EOR becomes an integral part of unconventional development.

The EOR papers I have had the privilege to review this year truly support these observations regarding the state of the industry. Novel EOR schemes, advancements in reservoir characterization leading to better insights into the recovery processes, and new physics and modeling techniques all demonstrate the high level of interest in EOR among operators, academia, and research organizations.

In closing, I have to remind myself that we have been waterflooding since the 1930s and the fundamental EOR schemes (i.e., chemicals and CO2) have been with us since the late 1960s. Low-salinity and hybrid schemes have been growing during the past 10 years, and we are getting better at establishing conformance controls such as foams and thermally activated polymers. If we also add the inclusion of completions and EOR-specific monitoring technologies to the enablers, it is easy to anticipate that more and more EOR will be considered a normal part of field optimization.

Technology Focus: Well Integrity and Well Control
Authors: Alcantara Santos Otto Luiz
Published: February 2017

Technology Focus

One of the more important aspects of well integrity during drilling operations is early kick detection. When an unintentional flow of the formation fluid into the wellbore occurs during conventional drilling operations, it must be detected promptly and the flow must be stopped, normally by closing the well. The early detection is crucial in minimizing the influx size. When the amount of formation fluid inside the well is large, especially if it is gas, the pressure inside the well will be higher during the subsequent well-control operations. This can lead to an increase in time to control the well or even to a worse situation: the loss of control. Another concern may be the amount of formation fluid to be handled at surface. Deepwater, high-pressure/high-temperature, and slimhole drilling are situations where early kick detection is mandatory.

The early kick detection is accomplished with a rig equipped with the appropriate kick-detection sensors and alarms and with a rig crew trained in quickly recognizing a kick and in the shut-in procedures. However, there are situations where early kick detection becomes more problematic—for example, when operating on a floating rig because of its motions, when using non-aqueous drilling fluids because of gas solubility, or during connections.

Recently, new technologies and research have been applied or developed to improve the kick-detection systems and to overcome some of the difficulties. To cite just a few examples,

Development of automated kick-detection systems (one of the papers summarized here addresses kick detection during connections)

Kick detection just above the bit using logging-while-drilling information

Kick detection using wired drillstring

Research on the effect on kick detection of gas solubility in nonaqueous drilling fluids (mineral oil, paraffin, ester, and olefins)

The use of managed-pressure-drilling systems (one of the papers recommended for additional reading comments on the advantage of this technology in reducing the kick size)

Influence of density flow on treated water turbidity in a sedimentation basin with inclined plate settler
Authors: Takata K. , Kurose R.
Published: February 2017

The removal efficiency of particulate matter from a sedimentation basin with an inclined plate settler in drinking water treatment facilities is sometimes reduced by density flow caused by temperature increases in the raw water. In this study, the structure of the density flow and its prevention are investigated by means of three-dimensional computational fluid dynamics (CFD). The results of CFD show that upward velocity is uniform and normal operations are performed before the increase in inlet water temperatures. After the onset of a temperature increase in the raw water, the upward flow velocity on the inclined plate settler increases, especially in the upstream zone of the plate. This velocity increment has a strong correlation with increase in turbidity as a result of the overflow of particulate matter. The effects of the installation of baffle plates on the inclined plate settler to reduce turbidity were explored. The CFD results using baffle plates show a significant decrease in upward velocity on the inclined plate settler. This suggests that baffle plates are effective in suppressing the overflow of particulate matter. To verify the prediction by CFD, baffle plates were installed in a drinking water treatment facility. The results show that the turbidity of treated water was reduced by the proposed procedure.
Electrochemical oxidation of quinoline aqueous solution on β-PbO2 anode and the evolution of phytotoxicity on duckweed

Published: February 2017

Electrochemical oxidation of quinoline on a β-PbO2 electrode modified with fluoride resin and the comprehensive toxicity of intermediates formed during oxidation on duckweed were investigated in detail. The results showed that quinoline was initially hydroxylated at the C-2 and C-8 positions by hydroxyl radicals (·OH) electro-generated on a β-PbO2 anode, yielding 2(1H)-quinolinone and 8-hydroxyquinoline, then undergoing ring cleavage to form pyridine, nicotinic acid, pyridine-2-carboxaldehyde and acetophenone, which were ultimately converted to biodegradable organic acids. NO3− was the final form of quinoline-N. The growth of duckweed exposed to the oxidized quinoline solution was gradually inhibited with the decrease in pH and the formation of intermediates. However, the growth inhibition of duckweed could be eliminated beyond 120 min of oxidation, indicating the comprehensive toxicity of the quinoline solution reduced when the amount of quinoline removed was above 80%. Additionally, the adjustment of the pH to 7.5 and the addition of nutrients to the treated quinoline solution before culturing duckweed could obviously alleviate the inhibition on duckweed. Thus, partial electrochemical degradation of quinoline offers a cost-effective and clean alternative for pretreatment of wastewater containing nitrogen-heterocyclic compounds before biological treatment. The duckweed test presents a simple method for assessing the comprehensive toxicity of intermediates.

Published: February 2017

Background:

Platelet-rich plasma (PRP) can provide an assortment of growth factors, but how PRP effects bone regeneration is still unknown. The aim of the study was to explore an optimal method of using PRP and bone marrow stromal cells (BMSCs).

Methods:

Anin vitroexperiment was first conducted to determine an appropriate quantity of PRP. BMSCs were cultured with PRP of different concentrations to assess cell proliferation and osteogenic differentiation. Following thein vitrostudy, a rat femoral segmental defect model was used. Five collagen mixtures consisting of different concentrations of PRP and BMSCs were prepared as follows, i) BMSCs and PRP (platelet 20 x 104/µl), ii) BMSCs and PRP (platelet 100 x 104/µl), iii) BMSCs and PRP (platelet 500 x 104/µl), iv) BMSCs, and v) PRP group (platelet 100 x 104/µl), were used to fill defect. New bone formation was evaluated by soft X-ray and histologic analyses were performed at 2, 4, 6 and 8 weeks postoperatively.

Results:

The cell proliferation increased PRP concentration-dependently. Cellular alkaline phosphatase activity was higher in moderate concentration than high or low concentration group’sin vitrostudy.In vivostudy, the bone fill percentage of newly formed bone in BMSCs and PRP (platelet 100 x 104/µl) was 46.9% at 8 weeks and increased significantly compared with other groups.

Conclusion:

BMSCs with moderate level of PRP significantly enhanced bone formation in comparison with BMSCs or PRP transplant in a rat femoral defect model.
