Oilfield development and operations planning under geophysical uncertainty
Authors: Redutskiy Yury 
Published: October 2017

Abstract
The oil and gas industry nowadays is challenged by dealing with nonconventional reserves and offshore environments. Decision-making associated with projects in the petroleum sector has to handle various technological issues, risks, and uncertainty. The Smart Fields approach was introduced to cope with complicated production conditions and make the production of hydrocarbons economically efficient. A significant part of this approach is proactive planning which implies taking into account the uncertainty, or lack of knowledge of the recoverable reserves, future hydrocarbon prices and various operational issues inherent in the projects. In this study, a multi-stage stochastic programming approach is employed to cover the relevant engineering issues of oilfield development and petroleum production while addressing the geophysical uncertainty related to the developed deposit. The proposed model covers such aspects as well drilling, gathering pipeline infrastructure planning, capacity selection for the infrastructure and the processing units, as well as planning the production operations with consideration of artificial lift efficiency. The model aims to optimise the entire field lifecycle, given the chosen planning criterion, that is an economic criterion of the project’s net present value. The contribution of the developed model to the area of planning in the petroleum industry is the detailed consideration of the technology: the flows and pressures in the planned infrastructure, reservoir behaviour, and the artificial lift performance. The goal of including these technological details is to apprehend the economic tradeoff between investments, operating costs and the prospective revenues, given the lack of knowledge of the geophysical properties of the developed deposit. The stochastic modelling implemented in this study is relevant to the development projects in nonconventional environments, where several deposits of various sizes are present; however, not each deposit's properties get to be studied in detail.

Published: October 2017

AbstractElectro-optic modulation is a key function in optical data communication and possible future optical compute engines. The performance of modulators intricately depends on the interaction between the actively modulated material and the propagating waveguide mode. While a variety of high-performance modulators have been demonstrated, no comprehensive picture of what factors are most responsible for high performance has emerged so far. Here we report the first systematic and comprehensive analytical and computational investigation for high-performance compact on-chip electro-optic modulators by considering emerging active materials, model considerations and cavity feedback at the nanoscale. We discover that the delicate interplay between the material characteristics and the optical mode properties plays a key role in defining the modulator performance. Based on physical tradeoffs between index modulation, loss, optical confinement factors and slow-light effects, we find that there exist combinations of bias, material and optical mode that yield efficient phase or amplitude modulation with acceptable insertion loss. Furthermore, we show how material properties in the epsilon near zero regime enable reduction of length by as much as by 15 times. Lastly, we introduce and apply a cavity-based electro-optic modulator figure of merit, Δλ/Δα, relating obtainable resonance tuning via phase shifting relative to the incurred losses due to the fundamental Kramers-Kronig relations suggesting optimized device operating regions with optimized modulation-to-loss tradeoffs. This work paves the way for a holistic design rule of electro-optic modulators for high-density on-chip integration.

Published: October 2017

AbstractHeavy metals (arsenic and manganese), particulate matter (PM), benzene, toluene, ethylbenzene, xylenes (BTEX), polycyclic aromatic hydrocarbons (PAHs) and endocrine disrupting chemicals (EDCs) have been linked to significant neurodevelopmental health problems in infants, children and young adults. These substances are widely used in, or become byproducts of unconventional oil and natural gas (UOG) development and operations. Every stage of the UOG lifecycle, from well construction to extraction, operations, transportation and distribution can lead to air and water contamination. Residents near UOG operations can suffer from increased exposure to elevated concentrations of air and water pollutants. Here we focus on five air and water pollutants that have been associated with potentially permanent learning and neuropsychological deficits, neurodevelopmental disorders and neurological birth defects. Given the profound sensitivity of the developing brain and central nervous system, it is reasonable to conclude that young children who experience frequent exposure to these pollutants are at particularly high risk for chronic neurological diseases. More research is needed to understand the extent of these concerns in the context of UOG, but since UOG development has expanded rapidly in recent years, the need for public health prevention techniques, well-designed studies and stronger state and national regulatory standards is becoming increasingly apparent.
Chromosome Numbers of Four Nigerian Species of Cola Schott. & Endlicher (Sterculiaceae).
Authors: Adebola P. O. , Morakinyo J. A. 
Published: October 2017

Abstract
This paper reports the results of chromosome countings in four wild Cola species (Cola lateritia, C. ballayi, C. verticillata and C. gigantea). Cytological investigation of these species gave a constant mitotic chromosome counts of 2n = 4x = 40 for the first time. The karyotypes were found to consist mostly of metacentric and submetacentric chromosomes. In addition to confirming the chromosome numbers and ploidy levels in these species, the results also reveals high symmetry and homogeneity of the karyotypes with those of the cultivated species (C. nitida and C. acuminata) already reported. The similarity in chromosome morphology between the cultivated and wild species indicate their common origin and suggests the possibility of using these wild species as bridges for gene transfer in Cola breeding programmes involving interspecific hybridization.
Reproductive Success of Pollen Derived From Selected and Non-Selected Sources and its Impact on the Performance of Crops in a Nematode-Resistant Japanese Black Pine Seed Orchard

Published: October 2017

Abstract
The reproductive success of pollen derived from selected and non-selected sources and its impact on the performance of orchard crops were evaluated, using five pairs of microsatellite markers, in a Japanese black pine (Pinus thunbergii Parl.) clonal seed orchard consisting of 16 nematode-resistant clones. The paternity of each open-pollinated seed was determined by comparing the genotypes of seeds from six clones (24 trees) with genotypes of the 16 orchard clones and two trees (N1, N2) representing other genotypes that had been inadvertently included in the orchard. Out of 384 seeds examined, the paternity of 316 seeds (82.3%) was assigned to the clones within the seed orchard. On average, the male reproductive success of orchard clones varied from 0.0% to 10.5%, and was significantly related to the male-flowering fecundity of each clone. It was not related to the synchrony of flowering phenology between mates. The expected proportions of seeds produced by clonal trees as a result of pollination by orchard clones, and by contaminating pollen originating from internal and external sources were estimated at 86.8%, 3.3% and 9.9%, respectively. Nematode-resistant seedlings of Japanese black pine were produced from surviving 2-yr seedlings that had previously been inoculated with pinewood nematode (Bursaphelenchus xylophilus). Without pollen contamination, the survival rate of seedlings produced by mating between resistant clones is expected to be 62.4%. However, in this orchard the figure was reduced to 57.5%, due to pollen contamination from both internal and external sources.
Identification of Molecular Markers for Selected Wood Properties of Norway Spruce Picea abies L. (Karst.) II. Extractives Content
Authors: Markussen T. , Tusch A. , Stephan B. R. , Fladung M. 
Published: October 2017

Abstract
We describe the development of a SCAR-marker linked to low extractives content of Norway Spruce (Picea abies L [Karst.]) derived from AFLPs. In these analyses 57 different primer enzyme combinations were used in a bulked segregant analysis approach comparing individuals with high and low extractives content. A total of 14 polymorphic AFLP markers were detected between the pools. Five markers were selected for further analyses to verify their linkage to extractives content based on individuals used for pool constitution. One AFLP marker, found to be significant linked to low extractives content was converted into a SCAR marker for further validation. For this marker, a monomorphic band was obtained by using sets of nested primers or restriction site specific primers (RSS) which include the AFLP-restriction recognition site. The separation of the marker from unlinked size homologous marker-alleles was realized by a SSCP-approach. Validation of the marker on different full-sib families confirmed the usability to separate the classes for low and high extractives content of Picea abies.

Published: October 2017

Abstract
The Inter-Simple Sequence Repeat (ISSR) was used in this study for genetic fingerprinting and identification of 28 important Populus L. (poplar) cultivars (varieties/ clones), and determination of the genetic relationships among these cultivars. These 28 cultivars belonged to sections Aigeiros, Tacahamaca, Leuce, Turanga, and hybrids between sections Aigeiros and Tacahamaca. Out of 27 ISSR primers tested, eight primers generated clear multiplex profiles. The best three primers produced 154 easily detectable fragments, 129 (84%) of which were polymorphic among the cultivars. Each of these 3 primers produced fingerprint profiles unique to each of the accessions studied, and thus could be solely used for their identification. Twenty-five markers, unique to 10 of the cultivars studied, were detected. These markers may be converted into cultivar-specific probes for identification purposes. Genetic relationships among the cultivars were evaluated by generating a similarity matrix based on the simple matching coefficient and the unweighted pair group method with arithmetic average (UPGMA) dendrogram. The results showed a clear-cut separation of cultivars among different sections of poplar, and were in agreement with the genealogy of the sampled cultivars. The present study shows that ISSR markers could generate abundant polymorphism, are reproducible, and are quick for characterization of poplar cultivars. In the future, the markers used in this study, in combination with other molecular techniques, could provide a useful panel of ISSR markers for largescale DNA fingerprinting of poplar cultivars and determination of the genetic relationships among these cultivars.
DNA From Ancient Cedar Wood From King Midas’ Tomb, Turkey, and Al-Aksa Mosque, Israel
Authors: Rogers S. O. , Kaya Z. 
Published: October 2017

AbstractAncient Taurus cedar (Cedrus libani A. Rich) wood samples from the Tumulus of King Midas at the Gordion archaeological site (about 2700 years old), near Ankara, Turkey, and from the Al-Aksa Mosque (about 1500 to 1900 years old), Jerusalem, Israel, were characterized by studying the sequences of ribosomal DNA (rDNA) internal transcribed spacers (ITS1 and ITS2). After extraction of the DNA, the ITS regions were amplified utilizing the polymerase chain reaction, followed by sequencing, BLAST searches for similar sequences, and phylogenetic analyses. Fifty-six sequences were obtained. In BLAST searches of existing sequence databases, most were closest to those from humans and fungi. However, two sequences exhibited similarities with conifer ITS sequences. One was an ITS1 region from the Gordion wood specimen, and the other one was an ITS2 region from the Al-Aksa wood specimen. Phylogenetic analyses indicated that both were closest to Taurus cedar (C. libani, also known as Lebanon cedar) ITS sequences from three recent samples of Taurus cedar from two sites in Turkey. However, they exhibited many differences from the recent C. libani rDNA ITS sequences from Turkey, probably due to degradation of the DNA in the ancient samples. The implications of the results on future studies are discussed.
Early Selection of Douglas-Fir across South Central Coastal Oregon, USA
Authors: Dean C. A. , Stonecypher R. W. 
Published: October 2017

AbstractDetails are given of three first-generation progeny tests (CB1, CB2 and CB3) of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) planted in the Coos Bay region of south-central coastal Oregon in 1973. The three tests included 15 polymix families based on a 10-pollen mix, and 27 families openpollinated on the ortet. The present study gives heritabilities and additive genetic correlations for growth measured between two and 17 years after planting. Correlated responses are estimated for volume at 17 years from early selection for height and diameter. Between four and 17 years after planting the individual heritability (h2) of height of coastal Douglas-fir across the Coos Bay tests was quite stable between h2= 0.18 and 0.22. The heritability of stem diameter age-forage was consistently much lower than for height. In the critical age range for early selection between five and 10 years the individual heritability of diameter ranged from h2= 0.07 to 0.10. The additive genetic correlations involving volume-17 and height or diameter increased to high values of rA= 0.80 to 0.84 between eight to 10 years after planting. Before seven years the absolute values of juvenilemature correlations were much lower. The higher heritability of height made this trait the best criterion for early indirect selection to improve mature stem volume growth. Across these Coos Bay tests, early selection on stem height measured at 5-8 years after planting was estimated to produce almost 40% more gain per year in volume-17 compared with direct selection at 17 years on volume-17 itself. The recommendation for maximizing gain per year in mature volume of coastal Douglas-fir at Coos Bay is to select on height at 7-8 years when the mean height of trees in tests should be around 4.5 to 5.5 meters.
Segregation and Linkage Relationships of Allozymes in Pinus Brutia Ten
Authors: Kaya Nuray , Isik K. 
Published: October 2017

Abstract
Female gametophytes of Pinus brutia Ten. were analyzed to study Mendelian segregation and linkage among allozyme loci in a seed orchard composed of 28 clones. Isozyme variants of nine enzyme systems encoding 14 loci from megagametophytes were assayed by starch gel electrophoresis. While six of the 14 loci were monomorphic, the remaining eight were polymorphic. Analysis of observed segregation ratios of all polymorphic loci except for Sdh1, showed a good fit to the 1:1 ratios expected for Mendelian inheritance. Linkage relationships of the eight polymorphic allozyme loci were analyzed by testing 23 of the 28 possible two-locus combinations. Two-locus segregations in three pairs (Got2- Mdh1, Got2-Pgi2 and Pgd3-Sdh1) were significantly heterogeneous (P ≤ 0.05). Relatively weak linkage was observed between only one pair of genes (Adh2:Got2). Recombination fraction for Adh2:Got2 was found to be 0.24 (± 0.06).
Značenje prijateljstva u procesu sazrijevanja – kršćanski pogled
Authors: Ninčević Marjan 
Published: October 2017

Smisao ovog rada je da nas podsjeti na vrijednost i važnost prijateljstva, da nas podsjeti kako je prijateljstvo važno u odrastanju i sazrijevanju, u ostvarivanju onog izvorno ljudskoga u nama. Prijateljstvo ne zavisi ni o kakvoj pripadnosti, prijateljstvo je bez-interesna dobrovoljnost kojoj ne treba nikakav posebni operativni program. U prijateljstvu je važna sloboda izbora i osjećajravnopravnosti. Prijateljstvo se razlikuje od drugih oblika ljubavi, bilo kao uzrok, sadržaj ili izražajna forma, ono je prava ljubav, a ljubav je i mogućnost razgovora. Prijateljstvo je jedino istinsko blago i prava sreća koja se pokazuje kao izravni učinak prijateljske ljubavi u obliku radosti, radosti koja izvire iz srca i koja može savršeno koegzistirati sa siromaštvom, čak i s boli. Prijateljstvo zbog svega ovoga treba odgoj, iznad svega duhovni odgoj koji čovjeku pojedincu može omogućiti da nadiđe dječja maštanja i postavi se u aktualnu stvarnost. Da usvoji jedno novo odgovorno 'ja', očišćeno od probuđenih tendencija koje se zaokružuju u prošlosti. Autentični prijatelj je stoga duhovno slobodan, zna poznavati samog sebe i drugog, ovisno o situaciji, zna biti dostupan za potpuno prihvaćanje drugoga, zna dati ljubav koja postoji i živi za prijatelja.
A NARRATIVA QUE DESVELA OS CONFLITOS SOCIOAMBIENTAIS NO BRASIL

Published: October 2017

RESUMO
Afirmar que há uma narrativa sobre conflitos socioambientais envolve identificar um esforço sistemático de divulgação de informações sobre essas situações nas quais há disputas, entre diferentes sujeitos, a partir dos usos de recursos do meio ambiente. Nosso argumento neste artigo é de que a Comissão Pastoral da Terra (CPT), ação pastoral da igreja católica, e a Fundação Instituto Oswaldo Cruz (Fiocruz), instituição pública vinculada ao Ministério da Saúde, elaboram esta narrativa formada por argumentos escritos, lançada à apreciação pública e que serve como instrumento de denúncia. A narrativa aparece no cruzamento feito entre 14 relatórios Conflitos no Campo Brasil, veiculados pela CPT anualmente desde 1985, e Mapa de Conflitos envolvendo Injustiça Ambiental e Saúde no Brasil, lançada em 2010 pela Fiocruz e atualizado periodicamente. Ambos são produtos distintos e há conexão entre eles, sendo os principais resultados deste trabalho a constatação da existência de uma narrativa comum e articulada que evidencia o conflito ambiental em um contexto de catástrofe e de seus riscos e formas de contenção, via percepção de seus sentidos complexos que emergem a partir do trabalho analítico com marcadores discursivos específicos.

Sehgal no invita a la lógica. Performance, experiencia y economía inmaterial en Tino Sehgal
Authors: Albarrán Juan 
Published: October 2017

<p>Tino Sehgal es uno de los artistas más reconocidos y aclamados de los últimos años. Su obra se concreta en situaciones (performances) que intérpretes contratados desarrollan en museos, bienales y galerías de todo el mundo. Esas situaciones nunca producen restos materiales (fotografías, objetos, partituras, contratos, etc.) que puedan ser exhibidos, publicados o coleccionados. Este artículo explora algunas de las contradicciones derivadas de la concepción del trabajo artístico en Sehgal, de su posición en el sistema internacional del arte, así como de las estrategias que ha desarrollado para tratar de escapar a las inercias institucionales y mercantiles en él dominantes. </p>
