Abstract:

Responses of three fish species were measured following the addition of neutrally buoyant weight-float combinations that increased rolling instability. The three species were creek chub, Semotilus atromaculatus, largemouth bass, Micropterus salmoides, and bluegill, Lepomis macrochirus. Ability to correct posture was predicted to increase with fin size and body depth in the order creek chub < largemouth bass < bluegill. In a 90-s period, the least added torque causing fish to roll to 90° in response to disturbances, ΔT90, and the least added torque making fish unable to recover from rolling, ΔTcrit, were measured as limits of ability to correct postural disturbances. Contrary to expectations, creek chub required a 58% increase in body torque to reach ΔT90, significantly larger than the 11% increase for largemouth bass and 19% increase for bluegill. Similarly, ΔTcrit was a 78% increase in body torque for creek chub, 43% for largemouth bass, and 34% for bluegill. Increased rolling torques resulted in behaviors reducing and avoiding rolling, including tilting, which reduces metacentric height, inverted swimming, which stabilizes fish, and contacting surfaces, which generates static forces. The superior ability of creek chub to correct postural disturbances may be explained by a fin arrangement that facilitates interactions with the ground.

Abstract:

Pleistocene glacial cycles associated with geological and climatic changes have been suggested to affect the distribution and abundance of marine organisms in the north-western Pacific. In addition to historical processes, several contemporary forces are associated with spatial distributions and genetic structuring of marine species. Herein, we gathered partial mitochondrial control region sequences of chub mackerel Scomber japonicus from 14 localities over most of its geographical range in the north-western Pacific to infer the effect of Pleistocene climatic fluctuations on its historical demography, and to assess the role of historical process and contemporary factors in shaping present-day patterns of genetic differentiation within this species. Phylogeographic patterns revealed two distinct lineages that originated in vicariance during the Middle Pleistocene. However, there was no evidence of phylogeographic partitioning of haplotypes over the sampled range. Population structure analyses indicated a high degree of genetic homogeneity among chub mackerel populations. Demographic analyses indicated both lineages experienced Late Pleistocene population expansion. The observed genetic pattern of chub mackerel is consistent with a scenario of the survival of this species in at least two allopatric glacial refugia during the glacial maxima of the Pleistocene followed by massive dispersals throughout the north-western Pacific and species-specific ecological processes facilitating contemporary gene flow.

Abstract:

This study aims to determine the pattern of fish consumption and to analyze factors that affect of it in Bengkulu City. This research was carried out from13 October 2015 until 17 May 2016. The method used to determine the pattern of fish consumption was descriptive method, and the method used to analyze the factors which affect the consumption of fish was multiple linear regression method with Ordinary Least Square (OLS). Based on the results of the study, fish consumption patterns in Bengkulu City was influenced by education and household income, the higher education and household income, the higher the amount of fish consumption and the quality of the fish consumed, the average of household consumption was 15.006 kg / month with the amount of consumption of marine fish is 62.81%, higher than the amount of consumption of freshwater fish (37.19%), and the proportion of expenditure for fish consumption was 16%. Age, family size, household income, price of Nile Tilapia and prices of goods substitution (chicken) affected the rate of consumption of Nile Tilapia significantly, while education variable did not affect the level of consumption of Nile Tilapia significantly. Age, Chub Mackerel prices and the prices of goods substitution (chicken) affected the consumption of Chub Mackerel significantly, while the variables of education, family size, and income did not affect the level of Chub Mackerel consumption in Bengkulu City.

Abstract:

A hypothesis has been erected stating that in the British Isles the acanthocephalan,Pomphorhynchus laeviscan be separated into 3 strains, an English, Irish and marine strain. Ecological and morphological evidence exists in support of this hypothesis. An investigation at the molecular level was conducted in order to test the validity of the existing evidence. A mitochondrial gene, subunit I of cytochrome c oxidase was partially sequenced from 3 Irish populations ofP. laevis, 1 Scottish population and 3 English populations.P. laevissequences from brown trout from Ireland, England and Scotland were very similar, showing a mean sequence divergence of 0·7%. Sequences from two populations ofP. laevisfrom English chub and bullhead were also similar to each other (0·35% divergence). These two groups of sequences, the brown trout group and the chub/bullhead group were 2·2% different. These data confirm the existence of at least 2 strains in Ireland and Britain, although there is evidence to suggest that these strains are defined by their host species rather than by their geographical distributions.

Abstract:

A linear regression model, where covariates and a response are subject to errors, is considered in this thesis. For so-called errors-in-variables (EIV) model, suitable error structures are proposed, various unknown parameter estimation techniques are performed, and recent algebraic and statistical results are summarized. An extension of the total least squares (TLS) estimate in the EIV model-the EIV estimate-is invented. Its invariant (with respect to scale) and equivariant (with respect to the covariates' rotation, to the change of covariates direction, and to the interchange of covariates) properties are derived. Moreover, it is shown that the EIV estimate coincides with any unitarily invariant penalizing solution to the EIV problem. It is demonstrated that the asymptotic normality of the EIV estimate is computationally useless for a construction of confidence intervals or hypothesis testing. A proper bootstrap procedure is constructed to overcome such an issue. The validity of the bootstrap technique is proved. A simulation study and a real data example assure of its appropriateness. Strong and uniformly strong mixing errors are taken into account instead of the independent ones. For such a case, the strong consistency and the asymptotic normality of the EIV estimate are shown. Despite of that, their...

Abstract:

ZusammenfassungMedium-term price continuation, commonly defined as momentum, is a widespread phenomenon in financial markets. It exists for individual stocks (Jegadeesh and Titman, 1993), for industry sectors (Moskowitz and Grinblatt, 1999), for style portfolios (Lewellen, 2002), in international equity markets (Rouwenhorst, 1998; Chui et al., 2010), and across asset classes (Bhojraj and Swaminathan, 2006; Menkhoff et al., 2012; Asness et al., 2013). Momentum also appears to be persistent over time, at least outside the U.S. stock market (Jegadeesh and Titman, 2001; McLean and Pontif, 2016; Green et al., 2017; Jacobs and Müller, 2020).

Abstract:

<em>Abstract.</em>—We assessed the structure of periphyton, benthic macroinvertebrate, and fish assemblages and their associations with environmental variables at 17 sites on streams of the highly urbanized Santa Ana River basin in Southern California. All assemblages exhibited strong differences between highly urbanized sites in the valley and the least-impacted sites at the transition between the valley and undeveloped mountains. Results within the urbanized area differed among taxa. Periphyton assemblages were dominated by diatoms (>75% of total taxa). Periphyton assemblages within the urbanized area were not associated with any of the measured environmental variables, suggesting that structure of urban periphyton assemblages might be highly dependent on colonization dynamics. The number of Ephemeroptera, Trichoptera, and Plecoptera (EPT) taxa included in macroinvertebrate assemblages ranged from 0 to 6 at urbanized sites. Benthic macroinvertebrate assemblages had significant correlations with several environmental variables within the urban area, suggesting that stream size and permanence were important determinants of distribution among the species able to survive conditions in urban streams. Only 4 of 16 fish species collected were native to the drainage. Fish assemblages of urbanized sites included two native species, arroyo chub <em>Gila orcuttii </em>and Santa Ana sucker <em>Catostomus santaanae, </em>at sites that were intermediate in coefficient of variation of bank-full width, depth, bed substrate, and water temperature. Alien species dominated urbanized sites with lesser or greater values for these variables. These results suggest that urban streams can be structured to enhance populations of native fishes. Continued study of urban streams in the Santa Ana River basin and elsewhere will contribute to the basic understanding of ecological principles and help preserve the maximum ecological value of streams in highly urbanized areas.

Abstract:

<em>Abstract.</em>—Limits to the capacity of the North Pacific Ocean to support salmon are suggested based on widespread observations of decreasing size and increasing age of salmon at maturation during time periods where the abundance of salmon has increased throughout the North Pacific rim. The increase in abundance of salmon is partially due to successful establishment of large-scale hatchery runs of chum salmon <em>Oncorhynchus keta </em>and pink salmon <em>O. gorbuscha</em>. The largest hatchery runs are chum salmon, and because of their long life span relative to the more abundant pink salmon, the increase in hatchery terminal run biomass under-represents the actual increase in salmon biomass. To put the increase in hatchery runs in perspective, the historical (since 1925) terminal runs and biomass of hatchery and wild pink, chum, and sockeye salmon <em>O. nerka </em>in the North Pacific Ocean were reconstructed. Various data sets of smolt releases from hatcheries, wild salmon estimates of smolt out-migrants, and subsequent adult returns by age and size were assembled. Age-structured models were fit to these data sets to estimate brood-year specific rates of natural mortality, growth, and maturation. The rates were then used to reconstruct total biomass of the “smolt data” stocks. The estimated ratio of terminal runs to total biomass estimated for the “smolt data” stocks were used to expand the historical time series of terminal run biomass on a species and area basis. The present total biomass (~4 million mt) of sockeye, chum, and pink salmon in the North Pacific Ocean is at historically high levels and is ~3.4 times the low levels observed in the early1970s. At least 38% of the recent ten-year average North Pacific salmon biomass is attributed to hatchery stocks of chum and pink salmon. Recent year terminal run biomass has been greater than the peak levels observed during the mid 1930s.

Abstract:

<em>Abstract.</em>—Microsatellite and major histocompatibility complex (MHC) variation was surveyed to evaluate population structure and the potential for genetic stock identification in chum salmon <em>Oncorhynchus keta </em>populations largely bordering the eastern Bering Sea and northwestern Gulf of Alaska. Variation at 14 microsatellite loci and one MHC locus was surveyed for 59 populations in the study. The genetic differentiation index (<em>F<sub>st</sub></em>) over all populations and loci was 0.023, with individual locus values ranging from 0.007 to 0.058. At least 10 regional stocks were observed in the survey area, with populations from Kotzebue Sound (mean <em>F<sub>st</sub> </em>value usually >0.02 in regional comparisons) and the Alaska Peninsula (<em>F<sub>st</sub> </em>>0.03) the most distinct of Alaskan populations surveyed. For stock identification applications incorporating DNA variation, chum salmon sampled in rivers’ tributaries to the eastern Bering Sea were classified into the following regions: Kotzebue Sound, Norton Sound, lower/middle Yukon River, Tanana River, Kuskokwim River, Nushagak River, north/central Bristol Bay, southwest Bristol Bay, northern Alaska Peninsula/Aleutian Islands, southwest Alaska Peninsula, and southeast Alaska Peninsula. For simulated single-region mixtures, estimated regional stock compositions were generally above 90% for the previously-listed regions except for the Kuskokwim River, Nushagak and north/central Bristol Bay regions. Incomplete characterization of DNA variation for populations in those regions most likely contributed to the lower accuracies of estimated stock compositions in the simulated mixtures. Estimated regional stock compositions of simulated samples comprising fish from several regions were within 1–3% of actual values provided that no contributions from the three under-represented regions were included in the simulated samples. Microsatellite and MHC variation has the potential to provide accurate estimates of regional stock composition for chum salmon fisheries in the Bering Sea and northern Gulf of Alaska.

Abstract:

Following the first result of generating nuclear fusion energy without dangerous radioactive radiation by laser ignition of the proton-11Boron reaction (HB11), we applied this method to evaluate other fusion reactions with no primary neutron production as the proton-7Lithium reaction (HLi7) and of the burning of solid density helium isotope 3He (He3-He3). The new method is a combination of now available laser pulses of 10 petawatt (PW) power and duration in the range of picoseconds (ps) or less. The new mechanism follows the initial theory of Chu and of Bobin for side-on ignition of solid state density fusion fuel developed in about 1972 where some later known physics phenomena had to be added. The essential innovation is the use of the discovery of a predicted anomaly when the mentioned laser pulses are sufficiently clean, i.e. free from prepulses by at least a contrast ratio 108 where acceleration by the nonlinear (ponderomotive) force is dominating.

Abstract:

In response to the recent rapid increase in power demand, Chubu Electric Power is now constructing two 1,650-megawatt power plants, each consisting of seven single-shaft combined-cycle units. These will be plant Nos. 3 and 4 of the Kawagoe Power Station. As one unit of plants, these power plants not only will be among the most powerful (in output) in the world, but will also offer the following features: 1) The main equipment of these plants, a gas turbine, will be a GE-Hitachi Model F7FA, the state-of-the-art 60 Hz model, for large equipment capacity and high efficiency. The heat recovery steam generator of each plant will use serrated fin tubes for high efficiency and compactness. 2) Plant efficiency will be at least 48.5% by means of optimizing the combined-cycle system and using the single-shaft triple-pressure reheat cycle. 3) As middle-load thermal plants, these plants are designed to use the advantages of a single-shaft combined cycle, thus offering operational convenience. 4) For global environmental preservation, which is nowadays an important concern of the local community, these plants are designed to reduce NOx emissions, warm discharge water, and noise. 5) To save labor for operation, and to improve its man-machine interface, these plant will utilize a large screen and CRT operation. Selection of these units and systems has entailed various feasibility studies and simulations for optimization, as well as new developments and reliability verifications. This paper takes the example of plant No. 3 to describe how the method of system selection and to present the design outline.
