Ex-Situ Bioremediation of Hydrocarbon Contaminated Soil - An Example from Oman
Authors: Alexandersen Dennis Kronborg , Headley Tom , Prigent Stephane , Mahmutoglu Ismail 
Published: September 2014

Abstract
A few years ago, an oil company in Oman initiated an approach to deal with hydrocarbon-contaminated soils that created environmental problems. These soils where collected in their oilfields and transported to their hazardous waste yards in the country's interior areas. The client entrusted several service providers to carry out de-contamination processes and landfill activities unfortunately with limited success.
One of the Waste Yards has stock piled large quantities of hydrocarbon contaminated soil, with contamination concentrations ranging from 15,000 mg/kg total Total Petroleum Hydrocarbons (TPH) soil up to 40,000 mg/kg TPH. The hydrocarbon molecule chains are from various types – starting with short chains i.e. C5 up to long chains C35.
In 2012, the client decided to implement a new remediation approach by deploying eco-friendly technologies to properly manage degradation and remediation of the contaminated soil by using modern bio-remediation technology developed and applied by a renowned German remediation company. The technology brings degradation results of reducing hydrocarbon contamination to less than 50%, lower than the international treatment standards and this within the first few weeks of treatment.
This paper will provide an overview of the bio-remediation approach used to treat stockpiled TPH contaminated soil. It will present remediation results from the field, but more over it will look into the opportunities and barriers for reusing the treated soil in civil projects without harming the environment and nature. In this specific case, the treated soil was used in one of the world's largest constructed wetlands, which handles 95,000 m3/day produced water. In April/May 2013, new soil tests will be taken to assess the quality of the soil material and subsequent hydrocarbon degradation after being in the wetland for one year.
Global Compliance and Sustainability Reporting Demands Place Growing Burden on Asset-Intensive Industries
Authors: Ladner Jeff , Cain David 
Published: September 2014

Abstract

Overview and Background
Sustainability has become an operational, fiscal, and strategic imperative for business, resulting in greater senior executive visibility and focus. For many companies, sustainability is more than an environmental concern. Mature sustainability programs can support bottom-line growth by identifying opportunities to reduce operational costs, increase efficiency and reduce risks.
As environmental reporting protocols become more complex and require more robust information, the ability to track and manage emissions is essential. Broad-based environmental tracking requires complete and accurate data to advance effective business decisions. Today's HSE reporting requirements also highlight the need for enterprise-level information management that can streamline data management and drive best practices.
Top corporate sustainability drivers revolve around cost reduction, managing compliance risk, securing revenues, and meeting stakeholder expectations. Potentially, the most impactful initiatives are aligned with heavy industrial production processes. In addition, emerging unconventional E&P processes require the ability to track and benchmark environmental effects to maintain a license to operate. Increasing scrutiny by governments, stakeholders and the public means higher risks related to accurate and timely disclosure.
Generating meaningful outcomes from a sustainability strategy is dependent on the ability to efficiently track and aggregate environmental data from numerous sources across operations and deliver up-to-the minute information to advance proactive decisions. Effective collection and calculation of environmental information is the first step toward development of a formal strategy for HSE management, with an eye toward establishing a path to sustainability.
This paper presents a new approach to compliance and sustainability reporting that progressively includes other stakeholders as it bridges the gap between operations and enterprise reporting needs.1
Environmental Scrutiny: Tracking up to the grain of sand!

Abstract
TOTAL ABK is a responsible operator that strives to minimize its environmental impacts in all phases of its operations. As such, regular assessments are undertaken to monitor these impacts and considerable efforts are deployed to their minimization. Committed to continuous improvement in environmental protection, we present a status report of various marine ecological impacts associated with our drilling activities.
Using latest and innovative technology, a full evaluation was done using a tailor made software for modeling drilling discharges. Two parts are critical to this environmental assessment: the impact of liquid releases associated with key mud chemicals and the impact of drill cuttings discharge on the seabed.
Current thinking usually considers drill cuttings discharge to have a limited and local impact, but this work demonstrates otherwise. Indeed, results of the liquid discharge indicate that the vertical and horizontal dispersion of chemicals can be quite extensive and not only within the vicinity of the discharge point. This is also verified with the outcome of the drilling discharge. Several scenarios were done including some with period up to 10 years in order to clarify the remediation time of the sediment and the potential impact on the local macro fauna decolonization.
By developing news tools able to monitor its environmental impacts, TOTAL ABK significantly contributes to widening scientific knowledge and demonstrates deep commitment towards UAE marine environmental protection.

Published: September 2014

Abstract
With an ever-growing global trend of outsourcing non-core business activities to third-party contractors across all industries, the challenge and opportunity lies in establishing a robust contractor management process.
Drawing from experience from over 370 Hiring Clients and 55,000+ contractor companies, mostly from the oil and gas industry, several key elements have been identified that are strategic attributes of leading edge contractor management practices. These are communication, consequences, guidelines, integration, and technology.
This paper demonstrates how these elements can foster an improved culture of prevention in the ever-growing sector of outsourced operations. These findings highlight the importance of consistent expectations and requirements tailored to local operating conditions in order to drive safety performance. Through use of a system for managing and evaluating contractor safety data, client companies have seen significant improvement in their contractors' performance. For companies that hire contractors, the elements discussed will assist by providing ideas for benchmarking and give useful and actionable takeaways for enhancing contractor management processes.
On the transverse Scalar Curvature of a Compact Sasaki Manifold
Authors: He Weiyong 
Published: September 2014

Abstract
We show that the standard picture regarding the notion of stability of constant scalar curvature metrics in Kähler geometry described by S.K. Donaldson [10, 11], which involves the geometry of infinitedimensional groups and spaces, can be applied to the constant scalar curvature metrics in Sasaki geometry with only few modification. We prove that the space of Sasaki metrics is an infinite dimensional symmetric space and that the transverse scalar curvature of a Sasaki metric is a moment map of the strict contactomophism group

Prediction of Reversed-Phase Liquid Chromatography Retention Parameters for Phenylisothiocyanate Derivatives of Amino Acids
Authors: Vorslova S. , Golushko J. , Galushko S. , Viksna A. 
Published: September 2014

Abstract
We report our experience with highly polar and charged analyte retention parameter prediction for a reversed-phase high-performance liquid chromatographic method. The solvatic retention model has been used to predict retention of phenylisothiocyanate derivatives of 25 natural amino acids under gradient elution conditions. Retention factors have been calculated from molecular parameters of analyte structures and from the column and eluent characteristics. A step-by-step method which includes the first guess prediction of initial conditions from structural formula and fine tuning of the retention model parameters using data from successive runs can substantially save method development time
Modeling repulsive forces on fibres via knot energies
Authors: Blatt Simon , Reiter Philipp 
Published: September 2014

Abstract Modeling of repulsive forces is essential to the understanding of certain bio-physical processes, especially for the motion of DNA molecules. These kinds of phenomena seem to be driven by some sort of “energy” which especially prevents the molecules from strongly bending and forming self-intersections. Inspired by a physical toy model, numerous functionals have been defined during the past twenty-five years that aim at modeling self-avoidance. The general idea is to produce “detangled” curves having particularly large distances between distant strands. In this survey we present several families of these so-called knot energies. It turns out that they are quite similar from an analytical viewpoint. We focus on proving self-avoidance and existence of minimizers in every knot class. For a suitable subfamily of these energies we show how to prove that these minimizers are even infinitely differentiable.
The comparison of FLOTAC, FECPAK and McMaster techniques for nematode egg counts in cattle
Authors: Bosco Antonio , Rinaldi Laura , Maurelli Maria , Musella Vincenzo , Coles Gerald , Cringoli Giuseppe 
Published: September 2014

AbstractThree methods, FLOTAC, FECPAK and McMaster were compared for accuracy and sensitivity for counting numbers of nematode eggs in faeces of naturally infected cattle with high or low nematode egg counts. Only FLOTAC gave positive results for 12 replicates from pooled samples with low egg counts making it more sensitive than FECPAK (67%) and McMaster (41.7%). FLOTAC resulted in generally higher egg counts and lower coefficients of variation than the other two methods used. The reliability of FECPAK and McMaster is depended on the area under the slide counted. All three methods can be used for making decisions whether to treat but FLOTAC or Mini-FLOTAC should be used for faecal egg count reduction tests when lower egg counts are present.

Published: September 2014

AbstractPCR-RFLP and nucleotide sequencing based genotyping of Toxoplasma gondii Indian isolates (Izatnagar and Chennai isolates and Chennai clone) vis-a vis RH-IVRI strain was conducted by targeting GRA6 as genetic marker. The 791 bp GRA6 product was PCR amplified from the genomic DNA of different T. gondii Indian isolates, including the RH-IVRI strain. Tru1I restriction endonuclease based PCR-RFLP of GRA6 sequence produced polymorphic digestion pattern that discriminated the virulent RH-IVRI strain (as type I) from the moderately virulent local isolates as type III. The PCR amplicon of T. gondii GRA6 from RH-IVRI strain as well as from the local isolates were cloned in cloning vector and custom sequenced. The nucleotide and deduced amino acid sequences of T. gondii isolates were aligned with that of the type I, II and III strains (RH, BEVERLEY, ME49, C56, TONT and NED) available in public domain and analyzed in silico using MEGA version 4.0 software. Nucleotide sequencing and phylogenetic analysis of GRA6 marker from the Indian isolates revealed a close genetic relationship with type III strains of T. gondii. Further, detection of a single nucleotide polymorphism (SNP) at positions 162 and 171 of the GRA6 marker, established the lineage of Indian isolates as type III. This is the first report on characterization of T. gondii lineage as type III in selective chicken population of India based on PCR-RFLP and sequence analysis of GRA6 gene.

AbstractGorgoderina spinosa sp. nov. (Digenea, Gorgoderidae) from the bladder of the water skipper, Euphlyctis cyanophlyctis (Anura, Dicroglossidae), from Dehradun, India is described and illustrated. Gorgoderina spinosa is the 6th Indian species assigned to the genus and is separated from its congeners based upon the morphology of vitelline glands and the presence of a spinose integument. Two additional digenean species, Diplodiscus amphichrus and Ganeo tigrinus, and 3 nematode species, Cosmocerca kalesari, Gendria chauhani, and unidentified larvae were found. Diplodiscus amphichrus, Ganeo tigrinus, Cosmocerca kalesari, and Gendria chauhani have previously been reported to infect Indian individuals of Euphlyctis cyanophlyctis.
Supplementary studies on Myxobolus tsangwuensis Chen, 1954 (Myxozoa: Myxosporea) infecting the gills of common carp Cyprinus carpio (L.): molecular and histological data

AbstractMyxobolus tsangwuensis Chen, 1954 is a common parasite infecting the gills of common carp Cyprinus carpio (L.). It was described simply in the original description and its molecular data was absent, which makes the accurate diagnosis challenging. Here we supplemented its description based on the morphological, histological and molecular data. It was characterized by the presence of small round or ellipsoidal plasmodia in the gills of host and histology showed the plasmodia developed in the capillary network of the gill lamella. Mature spores of M. tsangwuensis were ellipsodal in frontal view and lemon shaped in lateral view, averaging 11.2 ± 0.7 (10.2–12.5) μm × 9.3 ± 0.3 (8.5–10.0) μm × 6.2 ± 0.4 (5.5–7.0) μm. Spores valves were symmetrical and smooth. Occasionally, a small intercapsular appendix was observed. Two polar capsules were pyriform with different sizes, measuring 5.0 ± 0.2 (4.4–5.3) μm × 3.1 ± 0.1 (2.9–3.5) μm and 3.9 ± 0.2 (3.4–4.3) μm × 2.5 ± 0.2 (2.0–2.8) μm, respectively. Polar filaments coiled five to seven turns in large polar capsule and three to four turns in the small polar capsule. Some spores were surrounded by the mucous envelope that was not recorded in the original description. Molecular analysis revealed that the present SSU rDNA sequences did not match any available sequences in GenBank and phylogenetic analysis showed M. tsangwuensis was sister to M. basilamellaris and M. musseliusae.

AbstractThe present study reports the levels of mercury and selenium in Sarpa salpa and Balistes capriscus collected along the coast of Mahdia and Sfax (Tunisia). The systems constituted by S. salpa and Robphildollfusium fractum and by B. capriscus and Neoapocreadium chabaudi were tested as potential bioindicators to monitor environmental Hg pollution in marine ecosystems. Mercury and selenium concentrations were assessed in kidney, liver and muscle of 51 S. salpa and of 45 B. capriscus as well as in their respective endoparasites R. fractum and N. chabaudi. The Se:Hg molar ratios were evaluated for both species across the study areas. Surprisingly, the Se:Hg molar ratio in B. capriscus muscle from Mahdia is significantly lower than in Sfax. Our results indicate that some parasites may also be implicated in the amount of Se and Hg available in tissues and therefore contribute to oscillations of the Se:Hg molar ratios. In the model involving the carnivorous species (B. capriscus), the 5.1-times higher levels of mercury in N. chabaudi than in B. capriscus muscle in Sfax enable this fluke to be a sensitive biomonitoring tool for Hg pollution. The present results confirm that the habitual consumption of S. salpa should not suppose any potential health risk for Tunisian people. On the other hand, the consumption of B. capriscus may be of concern and further monitoring is advisable, since the Hg average concentration in Mahdia was above the maximum allowed Hg concentration in the edible portion of fish fixed by the European Union.

AbstractTwo new nematode species, Bakeria schadi sp. nov. and Falcaustra malaysiaia sp. nov. from the gastrointestinal tract of McGuire’s rock gecko, Cnemaspis mcguirei (Sauria: Gekkonidae) collected in Peninsular Malaysia are described. The two species now assigned to Bakeria are separated on the bases of male bursa type and location of the excretory pore: type II in B. schadi sp. nov. and type I in B. bakeri; location of excretory pore, anterior to nerve ring in B. schadi sp. nov. and posterior to nerve ring in B. bakeri. Falcaustra malaysiaia sp. nov. is most similar to F. chabaudi, F. concinnae, F. condorcanquii, F. barbi, F. dubia, and F. tchadi in that these 7 species possess 1 pseudosucker, 1 median papilla plus 10 pairs caudal papillae, and spicules with lengths between 1 and 2 mm. F. barbi and F. tchadi lack adcloacal papillae; the remaining 5 species possess 1 pair of adcloacal papillae. Falcaustra chabaudi is known from Nearctic salamanders; F. concinnae from Nearctic turtles; F. condorcanquii from Neotropical frogs, F. dubia from Oriental frogs, and F. malaysiaia sp. nov. from Oriental geckos. Two additional species of Nematoda were found, Cosmocerca ornata and Meteterakis singaporensis. Cnemaspis mcguirei represents a new host record for Cosmocerca ornata and Meteterakis singaporensis.
The genus Rhadinorhynchus (Acanthocephala: Rhadinorhynchidae) from marine fish in Australia with the description of four new species
Authors: Smales Lesley 
Published: September 2014

AbstractSpecies of Rhadinorhynchus, collected from Australian waters were examined. Specimens of Rhadinorhynchus from Scorpis aequipinnis, Girella tricuspidata, Johnius australis and Grammatobothus polyophthalmus could not be identified further. New host and locality records are reported for R. bicircumspinus found in Trachurus declivis and Rexea solandri from the east coast of Tasmania; R. carangis found in Trachinotus bailonii and T. copperingi from Queensland and Western Australian coasts; R. polynemi from Queensland; R. seriolae found in Seriola lalandi from the east coast of Australia. An immature female specimen of R. johnstoni provided no additional data on the species. Rhadinorhynchus biformis sp. nov., described from Pelates quadrilineatus and a trumpeter from Moreton Bay, Queensland differs from all its congeners in the pattern of the trunk spines, a single field of numerous small spines ventro-laterally, overlapping with irregular rows and circles of larger spines extending posteriorly. Rhadinorhynchus pichelinae sp. nov. described from Upeneichthys vlamingi from Point Peron, Western Australia differs from all its congeners in having proboscis armature of 10 longitudinal rows of 24–28, usually 26–27 hooks up to 87 long and a single field of 21–24 irregular circles of spines on the anterior trunk, with the posterior circles incomplete dorsally. Rhadinorhynchus polydactyli sp. nov. described from Polydactylus sp. from Moreton Bay is differentiated from all congenerics by the elongated neck of the females and having a proboscis armature of up to 34 hooks in 10 longitudinal rows. Rhadinorhynchus pomatomi sp. nov. found in Pomotomus saltrix differs from its most similar congeners, those without dorsal trunk spines, in having a proboscis armature of 12–15 rows of 20–22 hooks up to 73.5–80.5 long. Rhadinorhynchus bicircumspinus, R. biformis, R. pichelinae, R. polydactyli and R. pomatomi are known only from Australian waters while R. carangis and R. seriolae are also known from Japanese waters, R. johnstoni from the western Pacific and R. polynemi from the Indian coast.
