Abstract:
We present here the first results of Hg concentrations in three small shark species (Rhizoprionodon lalandei, R. porosus and Mustelus higmani) from the SE Brazilian coast. Mercury concentrations in R. lalandei ranged from 21.5 to 280.0 ng.g-1 dry weight (d.w.) (average 74.6 ng.g-1 d.w.; 17.9 ng.g-1 wet weight). In R. porosus, concentrations ranged from 7.6 to 90.5 ng.g-1 d.w. (average 42.2 ng.g-1 d.w., 9.4 ng.g-1 wet weight), whereas in M. higmani, concentrations ranged from 13.0 to 162.8 ng.g-1 d.w. (average 54.9 ng.g-1 d.w., 13.4 ng.g-1 wet weight). These concentration ranges are very low compared with values reported for other large shark species of the Southwestern Atlantic Ocean. There was a significant positive correlation between Hg concentrations and individual size, suggesting that biomagnification is occurring in these animals.

Abstract:
Indian mackerel is a group of small pelagic fish that has high economic value and is ecologically important. The catch of Indian mackerel in the Morodemak Coastal Fishing Port of Central Java has decreased within 2016-2018, which is suspected by overexploitation. This study aims to observe the reproduction of Indian mackerel. Fish samples were collected from the catches of the mini purse seine operated by fishermen in April-June 2019. The fish samples were measured their length and weight individually, then the abdomen dissected to collect gonad, and counted in sub-sample of the egg number. Data were analyzed to determine the length-weight relationship of fish, sex ratio, gonad maturity level (GML), gonad maturity index (GMI), the size of the first gonad matured, and the egg number in each gonad brood fish. The results showed a negative allometric length relationship, and the length-weight relation equation in female fish was W = 0.038 L 2.59 and in male was W = 0.178 L 2.03. The value of fish condition factors in males, and females obtained values ranging from 1-2. The proportion of fish in GML III ranges from 27.2 to 82.5%, while GML IV ranges from 3.6 to 33.8%. Fish GMI ranged from 0.17 to 4.75%. The eggs number ranged from 11.235 to 40.878 grain. The female Indian mackerel get the first gonad matured at the size of 15.2 cm.

Abstract:
For Canadians the Second World War traditionally evokes images of the invasion of Normandy, the Falaise Gap, and the ill-fated raid on Dieppe. Over the years Canadians who served overseas have been recognized but, at the same time, soldiers who served on the home front have been overlooked. This is because many of Canada's home defence soldiers were conscripted under the National Resources Mobilization Act, and were unwilling to go overseas. Thousands of Canadians, however, were denied entry into the regular forces because they were too old, too young, or classified as medically unfit. In British Columbia during the Second World War, these men were given the opportunity to enlist in a unique home guard unit called the Pacific Coast Militia Rangers (P.C.M.R.). The Pacific Coast Militia Rangers were organized in response to public pressure, and because existing coastal defences were inadequate. Composed of unpaid volunteers trained in guerilla tactics, the Pacific Coast Militia Rangers were a home defence force peculiar to British Columbia. The Rangers were not a typical military organization. Rather, they were a distinctively North American fighting force in the tradition of previous Ranger formations. A sense of historical tradition was evident in the designation of "Rangers" for British Columbia's Second World War guerilla home defence volunteers. In North America, since the 1700s, men born in and acquainted with the hinterland-frontiersmen, hunters, cowboys, and trappers proficient in the use of firearms-have been formed into irregular Ranger units in times of emergency. There is a long list of these North American Ranger organizations: Rogers' Rangers in the French and Indian War; Butler's Loyalist Rangers, the East Florida Rangers, and the Queen's Rangers in the American Revolution; the Frontier Battalion of the Texas Rangers in the revolution against Mexican authority; Mosby's Rangers in the U.S. Civil War; and the Rocky Mountain Rangers in the Northwest Rebellion. The Pacific Coast Militia Rangers were the twentieth century revival of this Ranger tradition. Throughout history, all Ranger units have used the same tactics: they employed guerilla warfare with an emphasis on surprise attacks, they operated in small units which were highly mobile, and they focussed on rifle training. A lack of formal military discipline has also been characteristic of all Ranger formations. The Pacific Coast Militia Rangers, then, were not an innovation in the Canadian military experience. They were part of a distinct military tradition of irregular troops adapted to suit North American frontier conditions. The Pacific Coast Militia Rangers reflected the character, fears, and internal conflicts of British Columbia's society. British Columbia was a predominantly white community and the P.C.M.R. mirrored the widespread white ethnic prejudices in the province. Ethnic groups were largely excluded from the Rangers and Native Indians, who were accepted as valuable recruits, were treated in a paternalistic manner. Militant trade unionism has been an important facet of B.C. history, and trade unionists were prominent in the Pacific Coast Militia Rangers. Trade unions fully supported the P.C.M.R. and Ranger membership was dominated by the working class. The labour movement's influence in the P.C.M.R. can be seen in the anxiety over the possible employment of Ranger units to break strikes. The role of war veterans in the P.C.M.R. also reflected the composition of the larger society. First World War veterans were a well-defined group in B.C. society, and their values and outlook were revealed through their Ranger participation. The veterans' zeal and rivalry with younger Rangers indicates that their patriotism was, at times, misguided, but it was rooted in a personal need to play a visible role in the war effort. The P.C.M.R. operated in a democratic manner: if the commander of a Ranger company was disliked by his men, he could be voted out of his position. Similarly, if Rangers disagreed with directives from P.C.M.E. headquarters they were quick to express their displeasure and threatened resignation. This would have been impossible in the regular army, but in the P.C.M.R.-composed of citizen-soldiers-it was a commonplace pattern. The social equality between ranks, and the egalitarian way in which the P.C.M.R. operated expressed the New World frontier values of British Columbia in the 1940s. The wartime fears and phobias of British Columbians showed in the actions of the Pacific Coast Militia Rangers. Life in British Columbia during the early years of the Second World War was, for the most part, as secure as life in other regions of Canada. This was changed, however, with the bombing of Pearl Harbor on 7 December 1941. The aggressiveness of Japan and the stunning success of her war machine, caused panic in the Pacific Coast province about the vulnerability of B.C. to an attack. In addition, the war sharpened the already existing white racial animosity against the Japanese, and _ provided a socially acceptable outlet for its expression. White British Columbia has had a history of fear of Asians and, subsequently, anti-Orientalism has been a current in the province's culture. In much the same way that anti-Japanese sentiment forced the federal government to intern and evacuate British Columbia's Japanese population, so too did public outcry prompt the formation of local home guard units. These two problems-the defence of British Columbia and anti-Japanese sentiment-became manifest in the history of the Pacific Coast Militia Rangers. From the Dominion government's viewpoint, the P.C.M.R. was a valuable organization. The Rangers provided military protection at a low cost, but they also comforted a frightened population which demanded protection from a Japanese invasion. It will be argued here that while the main purpose of the P.C.M.R. was home defence, the organization became much more than that to both the government and the people of British Columbia. Quite apart from its defence role, the P.C.M.R. provided reassurance, sustained the morale of a population at war, and acted as a means to indoctrinate civilians with military propaganda.

Abstract:
The West Tidewater earthflow, one of the largest in Oregon's history, occurred in December of 1994. The earthflow is located approximately 15 km north of Jewel, Oregon near the summit ofthe Northern Oregon Coast Range Mountains. The earthflow is 900 m long and 250 m wide, giving it a surface area of 9 ha, or 22 acres. Volume is 3.5 million m3. The earthflow occurred in low strength, well-bedded, tuffaceous, carbonaceous, micaceous, clay-rich mudstone, and very fine-grained, feldspathic, clay-rich siltstone of the lower Miocene age Northrup Creek Formation. The soil clay fractions contain up to 90% smectite with indications ofhalloysite. This earthflow is a reactivation ofa 650-year-old landslide (C-14 dating of uncovered buried trees). The failure mode is examined using a Janbu slope analysis and includes double wedge failure near the headscarp. High soil pore water pressure is one of the major causes of this slope failure. Rainfall levels for October, November, and December of 1994 were twice the previous five-year average. Present day groundwater level within the basin is less than one meter below ground surface. The earthflow is partially controlled by two faults of regional extent that dissect the basin near the headscarp in NW-SE and NE-SW directions. The Inceptisol soils in the basin remain moist below 20 cm year around. Soil in the basin may have been further weakened due to loss of root strength following timber harvest on the site in 1991. Soil liquid limits range from 42% to 95%, with PI values ranging from 2% to 77%. Soil clay content ranges between 18% and 30%. Direct shear tests on the mudstone and siltstone bedrock in both drained and undrained conditions produced internal friction angles of 14-18°, with cohesion values of 4 - 8 kPa. Back calculation of study area soil strength using the modified Bishop method results in a residual friction angle of 20.7°. The failure mode ofthe earthflow is from the headscarp downward and is modeled using Janbu methods. The study includes a detailed topographic map and a failure analysis of the earthflow basin.

Abstract:
Pathogens, such as Escherichia coli and fecal coliforms, are causing the majority of water quality impairments in U.S., making up ~87% of this grouping's violations. Predicting and characterizing source, transport processes, and microbial survival rates is extremely challenging, due to the dynamic nature of each of these components. This research built upon current analytical methods that are used as exploratory tools to predict pathogen indicator counts across regional scales. Using a series of non-parametric methodologies, with spatially explicit predictors, 6657 samples from non-estuarine lotic streams were analyzed to make generalized predictions of regional water quality. 532 frequently sampled sites in the Oregon Coast Range Ecoregion, were parsed down to 93 pathogen sampling sites in effect to control for spatial and temporal biases. This generalized model was able to provide credible results in assessing regional water quality, using spatial techniques, and applying them to infrequently or unmonitored catchments. This model's 56.5% explanation of variation, was comparable to other researchers' regional assessments. This research confirmed linkages to land uses related to anthropogenic activities such as animal operations and agriculture, and general riparian conditions.

Abstract:
LiDAR (Light Detection and Ranging) elevation data were collected in the Panther Creek Watershed, Yamhill County, Oregon in September and December, 2007, March, 2009 and March, 2010. LiDAR derived images from the March, 2009 dataset were used to map pre-historic, historic, and active landslides. Each mapped landslide was characterized as to type of movement, head scarp height, slope, failure depth, relative age, and direction. A total of 153 landslides were mapped and 81% were field checked in the study area. The majority of the landslide deposits (127 landslides) appear to have had movement in the past 150 years. Failures occur on slopes with a mean estimated pre-failure slope of 27° ± 8°. Depth to failure surfaces for shallow-seated landslides ranged from 0.75 m to 4.3 m, with an average of 2.9 m ± 0.8 m, and depth to failure surfaces for deep-seated landslides ranged from 5 m to 75m, with an average of 18 m ± 14 m. Earth flows are the most common slope process with 110 failures, comprising nearly three quarters (71%) of all mapped deposits. Elevation changes from two of the successive LiDAR data sets (December, 2007 and March, 2009) were examined to locate active landslides that occurred between the collections of the LiDAR imagery. The LiDAR-derived DEMs were subtracted from each other resulting in a differential dataset to examine changes in ground elevation. Areas with significant elevation changes were identified as potentially active landslides. Twenty-six landslides are considered active based upon differential LiDAR and field observations. Different models are used to estimate landslide susceptibility based upon landslide failure depth. Shallow-seated landslides are defined in this study as having a failure depth equal to less than 4.6 m (15 ft). Results of the shallow-seated susceptibility map show that the high susceptibility zone covers 35% and the moderate susceptibility zone covers 49% of the study area. Due to the high number of deep-seated landslides (58 landslides), a deep-seated susceptibility map was also created. Results of the deep-seated susceptibility map show that the high susceptibility zone covers 38% of the study area and the moderate susceptibility zone covers 43%. The results of this study include a detailed landslide inventory including pre-historic, historic, and active landslides and a set of susceptibility maps identifying areas of potential future landslides.

xi, 38 p. : ill. (some col.), maps
Splash dams were in-stream structures that were used to facilitate log driving in the Oregon Coast Range (OCR) between 1880 and 1957. This study explores the potential legacy impacts of "splashing" on stream morphology in Camp Creek and the West Fork Millicoma in the Southern OCR. Field data on stream morphology, GIS analysis, and hydraulic modeling were used in a paired-reach and paired-basin approach to determine legacy impacts on stream widths, depths, cross-sectional shapes, wood accumulation and sediment size. The paired-reach approach did not demonstrate significant differences up- or downstream of past dam locations. The paired-basin approach indicates that "splashing" is associated with narrower streams and less fine sediment, although it is not clear whether this difference reflects legacy impacts of splash dams or other factors driving variations between basins. Splash dam releases significantly exceeded 100-yr flood magnitudes in headwater regions and were comparable to 100-yr flows in lower reaches.

Undersea warfare (USW) was perceived as a large-area, deep-water operation in the past therefore Fleet USW training ranges were designed to meet these requirements. Currently the bigger threat is the likelihood of regional conflict throughout the world by aggressive nations in littoral waters. The U.S. Navy must stand ready to respond to these regional conflicts when national interests are threatened. Consequently, naval forces must train to operate in the littoral environments where such regional conflicts are likely to occur. The West Cost Shallow Water Undersea Warfare Training Range (WC SWUWTR) is being developed to provide this training.

Abstract:
Abstract A Permanent Magnet Motor (PMM) designed to break the 300°C barrier was previously presented that included many advancements to greatly improve the operating temperature and reliability beyond the ability of current equipment [1]. A key design element is the inclusion of a squirrel cage in the PMM rotor that results in a hybrid construction. This paper will delve into the rationale for the hybrid configuration and will assess motor performance using electromagnetic simulations and validation testing. PMMs are used in many industrial applications and have recently started to gain traction in oil and gas upstream production applications. A significant issue is the PMM compatibility with existing motor drive equipment and their need for special provisions to operate at the end of long cables without position sensors. A hybrid configuration help overcome these limitations and allows operation with conventional variable speed drives using a standard scalar controller as used with induction motors. The design, development, and qualification of the hybrid PM rotor construction were undertaken using a rigorous analytical approach combined with extensive validation testing. The motor is designed to maintain stability under the severe transient conditions in the SAGD environment, where the produced emulsion rich in gas and solids creates highly variable conditions for the motor and controller. A detailed electromagnetic model of the motor for configurations with or without the squirrel cage was undertaken to demonstrate the effectiveness of the hybrid configuration to maintain speed control stability. A time stepped method was used to simulate the motor start with simulated loading conditions, reflecting the starting and operating conditions with breakaway torques up to full load torque condition and 50% transient loads. The squirrel cage was successfully integrated within the rotor structure of a 150hp PM motor. Extensive design and thermal-structural analysis ensured the construction was acceptable for operation in the ranges −40°C to 350°C. Validation testing was then performed to demonstrate the hybrid PM motor construction functioned for use with conventional and legacy variable frequency drives.

Abstract:
Abstract This paper provides an overview of the qualification process of the highest power ESP ever installed into a hydrocarbon production system for artificial lift. The unit was selected and configured to interface with the existing deepwater offshore inflow and outflow systems without changes to the completion string or riser. The overall objective was to maximize the production capacity in terms of lift and flow rate given topsides power supply and running diameter constraints. The initial requirement was to identify a suitable supplier that could provide a hardware solution with a high technical readiness level. The team first reviewed the hydraulic performance of the existing production systems and modeled the potential for improvement with the new equipment configuration given an expected efficiency and power factor for the proposed motor. The ESP equipment was configured with components that had multiple qualification and validation testing requirements. The motor and associated high voltage connector were key differences from the existing systems. The pump design was modified to accommodate projected operating ranges including additional stages for the necessary head requirements. The new subcomponents were subjected to application specific testing to qualify the designs for operating conditions with multiple technical assurance reviews conducted by the end user and supplier company technical discipline authorities. Full scale flow testing at a dedicated facility (Gasmer) for Caisson gas/liquid separator ESP systems, and component installation stackup tests for fit and interfaces were completed to validate the performance in multiphase flow and identify hardware changes needed for the completion design and the intervention procedures. The qualification program was completed successfully, and a unit was deployed without incident, into a deepwater mudline caisson that has since been operated for live hydrocarbon production. The performance has met expectations and the unit efficiency and demonstrated capacity will allow for increased production. The use of a detailed qualification program that includes focused testing for individual system components and validation through full scale system integration testing ensures flawless deployment of technology improvements for critical well applications. The system is the highest power ESP for hydrocarbon production. It includes a novel completion design to accommodate the effective running diameter for the motor. The use of a unique shroud design to stay within running diameter constraints allowed for minor modifications to the completion string design without system changes to the riser or caisson. This was both cost effective and reduced the time needed for development and manufacturing.
