Understanding the Origin and Removal of Downhole Debris: Case Studies From the GOM
Authors: Javora Paul H. , Sanford Jack , Qu Qi , Robinson David , Poole Gary
Published: February 2008

Potential damage to the formation and generation of destructive wellbore debris can occur during perforating operations with shaped charges. One type of damage is to the formation, which is related in part to the powdered metals and metal alloys incorporated into the metal casings that contain the explosive charges in controlled debris perforating systems. Upon discharge, gun debris, including casing-metal residue and reaction products from the perforating system, can also contribute significantly to the overall amount of destructive wellbore debris generated. In addition, the debris often includes metal fragments from the wellbore casing, formation sand and other minerals, cement, and drilling fluid remnants that eventually are ejected into the wellbore. All of these materials can promote costly mechanical failures, contribute to well control problems, and hamper onsite operations.

Various factors influence the ultimate generation of destructive wellbore debris. These factors include gun type, fluid type, fluid density, bottom hole pressure and temperature, and the specific wellbore configuration and completion scenario employed. While previous authors have addressed formation damage issues or the impact resulting from the use of various casing metals, this work focused on the actual downhole debris generated and collected from the wellbore just after perforating the well, and relates these findings to the influencing factors. With the use of advanced downhole filtration and collecting techniques, downhole debris was collected from a series of deepwater projects in the GOM. Debris analysis coupled with well completion information has been studied. Results from the examination of downhole wellbore debris collected after perforating the well is presented and discussed.

Improved wellbore integrity and reduced risk are obtained through proper management of perforation and wellbore cleaning practices.

Published: February 2008

ABSTRACT Reduced to small isolated groups by anthropogenic habitat losses or habitat modifications, populations of many endangered species are sensitive to additive sources of mortality, such as predation. Predator control is often one of the first measures considered when predators threaten survival of a population. Unfortunately, predator ecology is often overlooked because relevant data are difficult to obtain. For example, the endangered Gaspésie caribou (Rangifer tarandus caribou) has benefited from 2 periods of predator control that targeted black bears (Ursus americanus) and coyotes (Canis latrans) in an attempt to reduce predation on caribou calves. Despite a high trapping effort, the number of predators removed has remained stable over time. To assess impact of predator movements on efficacy of a control program, we studied space use of 24 black bears and 16 coyotes over 3 years in and around the Gaspésie Conservation Park, Quebec, Canada, using Global Positioning System radiocollars. Annual home ranges of black bears averaged 260 km2and 10 individuals frequented area used by caribou. Annual home ranges of resident coyotes averaged 121 km2, whereas dispersing coyotes covered >2,600 km2. Coyotes were generally located at lower altitudes than caribou. However, because coyotes undertook long‐distance excursions, they overlapped areas used by caribou. Simulations based on observed patterns showed that 314 bears and 102 coyotes potentially shared part of their home range with areas used by female caribou during the calving period. Despite low densities of both predator species, extensive movement and use of nonexclusive territories seem to allow predators to rapidly occupy removal areas, demonstrating the need for recurrent predator removals. Our results underscore the necessity of considering complementary and alternative solutions to predator control to assure long‐term protection of endangered species.
Estimating Carrying Capacity for Sea Otters in British Columbia
Authors: GREGR EDWARD J. , NICHOL LINDA M. , WATSON JANE C. , FORD JOHN K. B. , ELLIS GRAEME M.
Published: February 2008

ABSTRACT We estimated carrying capacity for sea otters (Enhydra lutris) in the coastal waters of British Columbia, Canada, by characterizing habitat according to the complexity of nearshore intertidal and sub‐tidal contours. We modeled the total area of complex habitat on the west coast of Vancouver Island by first calculating the complexity of the Checleset Bay‐Kyuquot Sound (CB‐KS) region, where sea otters have been at equilibrium since the mid‐1990s. We then identified similarly complex areas on the west coast of Vancouver Island (WCVI model), and adapted the model to identify areas of similar complexity along the entire British Columbia coast (BC model). Using survey data from the CB‐KS region, we calculated otter densities for the habitat predicted by the 2 models. The density estimates for CB‐KS were 3.93 otters/km2and 2.53 otters/km2for the WCVI and BC models, respectively, and the resulting 2 estimates of west coast of Vancouver Island complex habitat carrying capacity were not significantly different (WCVI model: 5,123, 95% CI = 3,337–7,104; BC model: 4,883, 95% CI = 3,223–6,832). The BC model identified the region presently occupied by otters on the central British Columbia coast, but the amount of coast‐wide habitat it predicted (5,862 km2) was relatively small, and the associated carrying capacity estimate (14,831, 95% CI = 9,790–20,751) was low compared to historical accounts. We suggest that our model captured a type of high‐quality or optimum habitat prevalent on the west coast of Vancouver Island, typified by the CB‐KS region, and that suitable sea otter habitat elsewhere on the coast must include other habitat characteristics. We therefore calculated a linear, coast‐wide carrying capacity of 52,459 sea otters (95% CI = 34,264–73,489)—a more realistic upper limit to sea otters in British Columbia. Our carrying capacity estimates are helping set population recovery targets for sea otters in Canada, and our habitat predictions represent a first step in Critical Habitat identification. This habitat‐based approach to estimating carrying capacity is likely suitable for other nonmigratory, density‐dependent species.
Relationship of Obligate Grassland Birds to Landscape Structure in Wisconsin
Authors: MURRAY LES D. , RIBIC CHRISTINE A. , THOGMARTIN WAYNE E.
Published: February 2008

ABSTRACT  Conservation plans for grassland birds have included recommendations at the landscape level, but species' responses to landscape structure are variable. We studied the relationships between grassland bird abundances and landscape structure in 800‐ha landscapes in Wisconsin, USA, using roadside surveys. Of 9 species considered, abundances of only 4 species differed among landscapes with varying amounts of grassland and forest. Landscape variables explained <20% of variation in abundances for 4 of the 5 rarest species in our study. Our results suggest landscape‐based management plans for grassland birds might not benefit the rarest species and, thus, plans should incorporate species‐specific habitat preferences for these species.

Published: February 2008

ABSTRACT  Interactions between wolves (Canis lupus) and coyotes (C. latrans) can have significant impacts on their distribution and abundance. We compared diets of recently translocated Mexican wolves (C. l. baileyi) with diets of resident coyotes in Arizona and New Mexico, USA. We systematically collected scats during 2000 and 2001. Coyote diet was composed mostly of mammalian species, followed by vegetation and insects. Elk (Cervus elaphus) was the most common item in coyote scats. Mexican wolf diet had a higher proportion of large mammals and fewer small mammals than coyote diet; however, elk was also the most common food item in Mexican wolf scats. Our results suggest that Mexican wolf diet was more similar to coyote diet than previously reported, but coyotes had more seasonal variation. Considering results in other areas, we expect that Mexican wolves will have a negative impact on coyotes through direct mortality and possibly competition. Reintroduction of Mexican wolves may have great impacts on communities by changing relationships among other predators and their prey.
Effects of Global Positioning System Collar Weight on Zebra Behavior and Location Error
Authors: BROOKS C. , BONYONGO C. , HARRIS S.
Published: February 2008

ABSTRACT  Global Positioning System (GPS) collars are increasingly being used to study fine‐scale patterns of animal behavior. Previous studies on GPS collars have tried to determine the causes of location error without attempting to investigate whether the accuracy of fixes provides a correspondingly accurate measure of the animal's natural behavior. When comparing 2 types of GPS collar, we found a significant effect of collar weight and fit on the rate of travel of plains zebra (Equus burchelli antiquorum) females in the Makgadikgadi, Botswana. Although both types of collar were well within accepted norms of collar weight, the slightly heavier collars (0.6% of total body mass [TBM]) reduced rate of travel by >50% when foraging compared with the collar that was 0.4% of TBM. Collar effect was activity specific, particularly interfering with grazing behavior; the effect was less noticeable when zebras crossed larger interpatch distances. We highlight that small differences in collar weight or fit can affect specific behaviors, limiting the extrapolation of fine‐scaled GPS data. This has important implications for wildlife biologists, who hitherto have assumed that collars within accepted weight limits have little or no effect on animal movement parameters.
Translating Bait Preference to Capture Success of Northern White‐Tailed Deer

Published: February 2008

ABSTRACT  Wildlife management and research have depended upon trapping as an essential tool for decades. Although deer (Odocoileus spp.) capture by Clover traps remains a basic technique that has changed little over time, researchers use it as an integral part of field operations to support increasingly sophisticated and costly project objectives. Despite reports of deer preference for certain baits, no study has determined if bait preference can effectively increase capture success of free‐ranging deer. By supplementing corn bait with salt, peanut butter, or molasses, we tested effects of these bait treatments on capture success of free‐ranging white‐tailed deer (O. virginianus), as well as levels of nontarget animal disturbance in Clover traps, during February‐March 2005. With 1,446 adjusted trap‐nights and a 6.5% capture success rate, the probability of capture increased over time and varied among 4 study sites (df = 3, P < 0.005); however, we did not detect a significant effect of bait supplementation on capture success (df = 3, P > 0.8). Nontarget animal activity in the trap varied by site (df = 3, P < 0.001), bait treatment (df = 3, P=0.04), and Julian date (df=3, P < 0.001). Our results are the first to suggest that bait preference may not translate into actual improved capture success of free‐ranging deer. Future research should focus on testing additional baits or bait supplements to determine if an increase in trapping success and a minimization of trap disturbance by nontarget species occurs.
Distribution and Abundance of Endangered Florida Key Deer on Outer Islands

Published: February 2008

ABSTRACT  Status assessment of endangered Florida Key deer (Odocoileus virginianus clavium) is currently limited by a paucity of information regarding population estimates for outer islands, which collectively comprise approximately 70% of potential habitat within the Key deer range. Practical limitations and financial considerations render traditional survey techniques impractical for application on remote outer islands. Our objective was to evaluate the utility of infrared‐triggered cameras to estimate Key deer abundance on outer islands. We used digital infrared‐triggered cameras and mark‐resight methods to estimate Key deer abundance on 20 outer islands. Abundance estimates for primary subpopulations ranged from 15 to 16 for Howe Key, 5 to 10 for Knockemdown complex, and 13 to 17 for Little Pine Key. Other island complexes such as Ramrod Key, Water Key, and Annette complex maintain only small subpopulations (i.e., ≤5 individuals) and other previously inhabited island complexes (e.g., Johnson complex and Summerland Key) no longer maintain subpopulations. Key deer abundance was well below estimated carrying capacities on all outer islands, with larger natural populations occurring closest to Big Pine Key. Our results suggest that camera‐based surveys offer a practical method to monitor abundance and population trends of Key deer on outer islands. Our study is the first to estimate Key deer abundance in these areas using technically structured model‐based methods and provides managers with current and baseline information regarding Key deer subpopulations.
An Artificial Latrine Log for Swamp Rabbit Studies

Published: February 2008

ABSTRACT  Managers use latrine surveys to monitor swamp rabbit (Sylvilagus aquaticus) populations but may miss rabbits in sites lacking suitable latrine logs. We tested artificial latrine logs in logless thickets in southern Illinois, USA, generally detecting swamp rabbits in fewer visits than by live‐trapping. Artificial logs can aid swamp rabbit monitoring, especially in logless habitats.
DMSP – Database for Modeling Signaling Pathways
Authors: Breit M. , Pfeifer B. , Baumgartner C. , Modre-Osprian R. , Tilg B. , Visvanathan M.
Published: February 2008

Objectives:
Presently, the protein interaction information concerning different signaling pathways is available in a qualitative manner in different online protein interaction databases. The challenge here is to derive a quantitative way of modeling signaling pathways from qualitative way of modeling signaling pathways from a qualitative level. To address this issue we developed a database that includes mathematical modeling knowledge and biological knowledge about different signaling pathways.

Methods:
The database is part of an integrative environment that includes environments for pathway design, visualization, simulation and a knowledge base that combines biological and modeling information concerning pathways. The system is designed as a client-server architecture. It contains a pathway designing environment and a simulation environment as upper layers with a relational knowledge base as the underlying layer.

Results:
DMSP – Database for Modeling Signaling Pathways incorporates biological datasets from online databases like BIND, DIP, PIP, and SPiD. The modeling knowledge that has been incorporated is based on a literature study. Pathway models can be designed, visualized and simulated based on the knowledge stored in the DMSP. The user can download the whole dataset and build pathway models using the knowledge stored in our database. As an example, the TNF? pathway model was implemented and tested using this approach.

Conclusion:
DMSP is an initial step towards the aim of combining modeling and biological knowledge concerning signaling pathways. It helps in understanding pathways in a qualitative manner from a qualitative level. Simulation results enable the interpretation of a biological system from a quantitative and systemtheoretic point of view.
Modeling Repeated Time-to-event Health Conditions with Discontinuous Risk Intervals
Authors: Guo Z. , Gill T. M. , Allore H. G.
Published: February 2008

Objectives:
Researchers have often used rather simple approaches to analyze repeated time-to-event health conditions that either examine time to the first event or treat multiple events as independent. More sophisticated models have been developed, although previous applications have focused largely on such outcomes having continuous risk intervals. Limitations of applying these models include their difficulty in implementation without careful attention to forming the data structures.

Methods:
We first review time-to-event models for repeated events that are extensions of the Cox model and frailty models. Next, we develop a way to efficiently set up the data structures with discontinuous risk intervals for such models, which are more appropriate for many applications than the continuous alternatives. Finally, we apply these models to a real dataset to investigate the effect of gender on functional disability in a cohort of older persons. For comparison, we demonstrate modeling time to the first event.

Results:
The GEE Poisson, the Cox counting process, and the frailty models provided similar parameter estimates of gender effect on functional disability, that is, women had increased risk of bathing disability and other disability (disability in walking, dressing, or transferring) as compared to men. These results, especially for other disabilities, were quite different from those provided by an analysis of the first-event outcomes. However, the effect of gender was no longer significant in the counting process model fully adjusted for covariates.

Conclusion:
Modeling time to only the first event may not be adequate. After properly setting up the data structures, repeated event models that account for the correlation between multiple events within subjects can be easily implemented with common statistical software packages.
Intravenous iron: From anathema to standard of care
Authors: Auerbach Michael , Coyne Dan , Ballard Harold
Published: February 2008

A growing body of literature supports the use of intravenous iron as a compliment to erythropoiesis stimulatory therapy and in a significant number of disease states where iron is necessary and oral iron is ineffective or not tolerated. The differences in efficacy, safety, and clinical nature of serious adverse events that occur with the various iron preparations are poorly understood. Misinterpretation of adverse events leads to underutilization of this important treatment modality. Understanding the history of the development and use of intravenous iron is crucial to appreciate its importance in the management of anemias of dialysis, cancer, and cancer chemotherapy and properly assess side effects and toxicity. The benefits seen with intravenous iron therapy are independent of the pretreatment levels of serum ferritin, iron, total iron binding capacity, and percent transferrin saturation. Intravenous iron has been shown to overcome hepcidin induced iron restricted erythropoiesis in iron‐replete patients. Available clinical and experimental data suggest that increased utilization of intravenous iron should be considered. Am. J. Hematol., 2008. © 2008 Wiley‐Liss, Inc.

Published: February 2008

Among adults with sickle cell disease (SCD), pulmonary complications are a leading cause of death. Yet, the natural history of lung function in adults with SCD is not well established. We conducted a retrospective cohort study of adults with SCD who had repeated pulmonary function tests performed over 20 years of age. Ninety‐two adults were included in this cohort. Rate of decline in FEV1 for men and women with SCD was 49 cc/year (compared with 20–26 cc/year in the general population). Further studies are needed to identify factors which impact the rate of lung function decline in adults with SCD. Am. J. Hematol. 2008. © 2008 Wiley‐Liss, Inc.
Three characteristic reactions of alkynes with metal compounds in organic synthesis
Authors: Omae Iwao
Published: February 2008

Alkynes have two sets of mutually orthogonal π‐bonds that are different from the π‐bonds of alkenes. These π‐bonds are able to bond with transition metal compounds. Alkynes easily bond with the various kinds of compounds having a π‐bond such as carbon monoxide, alkenes, other alkynes and nitriles in the presence of the transition metal compounds. The most representative reaction of alkynes is called the Pauson–Khand reaction. The Pauson–Khand reactions include the cyclization of alkynes with alkenes and carbon monoxide in the presence of cobalt carbonyls. Similar Pauson–Khand reactions also proceed in the presence of other transition metal compounds. These reactions are the first type of characteristic reaction of alkynes. Other various kinds of cyclizations with alkynes also proceed in the presence of the transition metal compounds. These reactions are the second type of characteristic reaction of alkynes. These include cyclooligomerizations and cycloadditions. The cyclooligomerizations include mainly cyclotrimerizations and cyclotetramerizations, and the cycloadditions are [2 + 2], [2 + 2 + 1], [2 + 2 + 2], [3 + 2], [4 + 2], etc., type cycloadditions. Alkynes are fairly reactive because of the high s character of their σ‐bonds. Therefore, simple coupling reactions with alkynes also proceed besides the cyclizations. The coupling reactions are the third type of characteristic reactions of alkynes in the presence of, mainly, the transition metal compounds. These reactions include carbonylations, dioxycarbonylations, Sonogashira reactions, coupling reactions with aldehydes, ketones, alkynes, alkenes and allyl compounds.

Published: February 2008

The title compound and its corresponding etheno‐ and ethano‐bridged compounds were successfully synthesized in enantiomerically pure form by McMurry coupling of 2,2′‐dimethoxy‐(R)‐ or ‐(S)‐1,1′‐binaphthyl‐6,6′‐dicarbaldehydes as the key reaction. The reaction proceeded in a highly diastereoselective manner; the reaction of the racemic dialdehyde did not afford the meso coupling product but gave only the racemic one in poor yield. The diyne crystallized in the chiral monoclinic space group P21 from toluene/hexane. Structural analysis reveals that it has a considerably twisted double‐helical structure in crystal form. The spectral properties (NMR, UV/Vis, and CD) clearly indicate the highly strained nature of the molecule. In particular, its UV/Vis and CD spectra exhibit a bathochromic shift of about 20 nm for the naphthyl π–π* transitions.

In order to put the previously proposed concept of directed evolution of hybrid catalysts (proteins that harbor synthetic transition‐metal catalysts or organocatalysts) into practice, several prerequisites must be met. The availability of a robust host protein that can be expressed in sufficiently large amounts, and that can be purified in a simple manner is crucial. The thermostable enzyme tHisF from Thermotoga maritima, which constitutes the synthase subunit of a bi‐enzyme complex that is instrumental in the biosynthesis of histidine, fulfills these requirements. In the present study, fermentation has been miniaturized and parallelized, as has purification of the protein by simple heat treatment. Several mutants with strategically placed cysteines for subsequent bioconjugation have been produced. One of the tHisF mutants, Cys9Ala/Asp11Cys, was subjected to bioconjugation by the introduction of a variety of ligands for potential metal ligation, of a ligand/metal moiety, and of several organocatalytic entities that comprise a flavin or thiazolium salts. Characterization by mass spectrometry and tryptic digestion was achieved. As a result of this study, a platform for performing future directed evolution of these hybrid catalysts is now available.

Published: February 2008

The Pd/C‐catalyzed H2–D2 exchange reaction using a H2–D2O combination provided a general, efficient and environmentally friendly route for the preparation of deuterium gas (D2). H2 sealed in a reaction flask was converted into nearly pure D2, which could be used for the Pd/C‐catalyzed one‐pot reductive deuteration of various reducible functionalities and the chemoselective one‐pot deuterogenation of olefin and acetylene. Additionally, we established the capturing method of the generated D2 in a balloon, which was successfully applied to the Pd/C‐catalyzed reductive mono‐N‐alkylation of a primary amine using nitrile as the alkylating reagent.
