The goal of this study was to determine the year round movement patterns of American horseshoe crabs, Limulus polyphemus, in the Great Bay Estuary, New Hampshire (USA) by using acoustic telemetry to track the movements of 37 adult Limulus, for periods ranging from 2 to 31 months. During the winter (December-March) horseshoe crabs moved very little. In the spring, when water temperatures exceeded II^C, horseshoe crabs moved at least 1 km further up into the estuary to shallower subtidal areas about a month prior to spawning. The mean distance traveled during spring migrations was 2.6 + 0.5 (n=20) km up the estuary. Mating occurred in May and June and during these months animals spent most of their time in shallow subtidal areas adjacent to mating beaches. In the summer (July-Augnst), animals moved 1.5 ± 0.5 (n=26) km down the estuary, towards the ocean, and ranged widely, using extensive portions of the estuary. In the fall (September-November) movement was more limited (0.5 ± 0.5 km; n = 24) while animals settled into wintering locations, where they remained until spring. The mean annual linear range for all animals was 4.5 ± 0.3 km (n =35) and the maximum distance traveled by an individual horseshoe crab within one year was 9.2 km. There was no evidence that any of the horseshoe crabs tracked during this study left the estuary 展开更多

While eye sensitivity in the American horseshoe crab Limulus polyphemus has long been known to be under the control of an endogenous circadian clock, only recently has horseshoe crab locomotion been shown to be controlled by a separate clock system. In the laboratory, this system drives clear activity rhythms throughout much of the year, not just during the mating season when horseshoe crabs express clear tidal rhythms in the field. Water temperature is a key factor influencing the expression of these rhythms: at 17~C tidal rhythms are expressed by most animals, while at I l^C expression of circatidal rhythms is rarely seen, and at 4~C rhythms are suppressed. Neither long (16:8 Light:Dark) nor short (8:16) photoperiods modify this behavior at any of these temperatures. Synchronization of these circatidal rhythms can be most readily effeeted by water pressure cycles both in situ and in the lab, while temperature and current cycles play lesser, but possibly contributory, roles. Interestingly, Light:Dark cycles appear to have synchronizing as well as "masking" effects in some individuals. Evidence that each of two daily bouts of activity are independent suggests that the Limulus circatidal rhythm of locomotion is driven by two (circalunidian) clocks, each with a period of 24.8h. While the anatomical locations of either the circadian clock, that drives fluctuations in visual sensitivity, or the circatidal clock, that controls tidal rhythms of locomotion, are currently unknown, preliminary molecular analyses have shown that a 71 kD protein that reacts with antibodies directed against the Drosophila PERIOD (PER) protein is found in both the pro- tocerebrum and the subesophageal ganglion 展开更多

An iterative optimization strategy for fed-batch fermentation process is presented by combining a run-to-run optimization with swarm energy conservation particle swarm optimization (SEC-PSO). SEC-PSO, which is designed with the concept of energy conservation, can solve the problem of premature convergence frequently appeared in standard PSO algorithm by partitioning its population into several sub-swarms according to the energy of the swarm and is used in the optimization strategy for parameter identification and operation condition optimization. The run-to-run optimization exploits the repetitive nature of fed-batch processes in order to deal with the optimal problems of fed-batch fermentation process with inaccurate process model and unsteady process state. The kinetic model parameters, used in the operation condition optimization of the next run, are adjusted by calculating time-series data obtained from real fed-batch process in the run-to-run optimization. The simulation results show that the strategy can adjust its kinetic model dynamically and overcome the instability of fed-batch process effectively. Run-to-run strategy with SEC-PSO provides an effective method for optimization of fed-batch fermentation process. 展开更多

AIM: To investigate whether American ginseng (AG, Panax quinquefolium) supplementation was able to improve endurance exercise performance.METHODS: Thirteen physically active male college students were divided into two groups (AG or placebo)and received supplementation for 4 wk, before the exhaustive running exercise. Treadmill speed was increased to a pace equivalent to 80% VO2max of the subject. A 4-wk washout period followed before the subjects crossed over and received the alternate supplement for the next 4 wk.They then completed a second exhaustive running exercise. The physiological variables that were examined included time to exhaustion and oxygen pulse. Moreover,the plasma creatine kinase (CK) and lactate were measured prior to the exercise, at 15 and 30 min during exercise,immediately after exercise, and 20, 40, 60, and 120 min after exercise.RESULTS: The major finding of this investigation was that the production plasma CK during the exercise significantly decreased for group AG than for group P. Secondary physiological finding was that 80% VO2max running was not improved over a 4-wk AG supplementation regimen.CONCLUSION: Supplementation with AG for 4 wk prior to an exhaustive aerobic treadmill running reduced the leakage of CK during exercise, but did not enhance aerobic work capacity. The reduction of plasma CK may be due to the fact that AG is effective for the decrease of skeletal muscle cell membrane damage, induced by exercise during the high-intensity treadmill run. 展开更多

American horseshoe crabs Limulus polyphemus were tracked using acoustic telemetry and traditional tagging in a semi-enclosed bay on Cape Cod (Pleasant Bay), Massachusetts, USA, to determine seasonal movement patterns. Fifty-five actively spawning females were fitted with transmitters in 2008 and 2009 and were tracked using acoustic telemetry from May 2008 through July 2010. Fil^een crabs with transmitters also had archive depth-temperature tags attached. In addition, over 2000 spawning crabs (males and females) were tagged with US Fish and Wildlife CIdSFWS) button tags over the same period. Ninety-one percent of the crabs with transmitters were detected during this study. In the spring, crabs were primarily located in the northern section of the bay near spawning beaches, whereas in the fall crabs moved towards the deeper portions of the bay, and some may have overwIntered in the bay. There was evidence that a majority (58%-71%) of the females with transmitters spawned in two sequential seasons. One archive tag was recovered resulting in a year-long continuous record of depth and tem- perature data that, when integrated with telemetry data, indicated that the crab overwintered in the bay. The live recapture rate of crabs with USFWS button tags was 11%, with all re-sighted crabs except one observed inside Pleasant Bay. Eighty-three percent of recaptures were found within 2.5kin of the tagging location, and 51% were observed at the same beach where they were tagged. This study provides further evidence that horseshoe crabs in Pleasant Bay may be philopatric to this embayment 展开更多

Maritime transportation is one of the most important and extensive transportation modes in the world. Maritime transportation is the backbone of contemporary world trade and therefore special attention should be paid to all subjects concerning this mode of transportation. It is also necessary to complement maritime transportation by other modes, such as rail and/or truck (road). This article deals with the problems of maritime transportation and provides the summary of recent developments, trends and statistics mainly on transatlantic maritime routes (Europe to US). Besides maritime transportation, this thesis also reviews the trends and statistics of rail and truck (road) transportation in US and Europe. The authors considers four Czech biggest cities (points of origin), five European ports, eight US ports and 10 biggest cities in US (points of destination). The adapted TCMMSP (transnational collaborative multi-mode shipping problem) is applied to this case study and it seeks to solve the transportation of a set of five shipments with unique O-D (origin-destination) pairs and volume. The end of the thesis summarizes the results and analyses the average costs, optimal set volume, optimal shipment routing and port analysis. 展开更多

The United States Congress set a benchmark in US anti-human trafficking policy with the Trafficking Victims Protection Act of 2000 (TVPA 2000J. The TVPA 2000 and its subsequent reauthorizations in 2003, 2005, and 2008 were put forth to increase the scope, focus, and effectiveness of US efforts to combat human trafficking. In-depth analyses of each reauthorization provide an understanding of the aims of the TVPA. The evolution of the TVPA reauthorizations dearly demonstrates that the US is committed to thwarting human trafficking both domestically and internationally. The analyses examine strengths and weaknesses of the legislation and provide insight as to how the TVPA reached its current state as the William Wilberforce Trafficking Victims Protection Reauthorization Act of 2008 (TVPRA 2008). Drawing from the evolution of TVPA legislation, the future of the human trafficking phenomenon and legislation is discussed. 展开更多

More than 4,000,000 immigrants traveled from Italy to the United States between 1880 and 1924. Most were peasants, largely illiterate, and with no sense of an Italian identity as their ancestral home had only been liberated from centuries of foreign rule in 1861. This study utilizes primary and secondary documents, as well as archival sources and interviews to determine the role of sport in the transition to an Italian identity, and then an American identity within the assimilation process. Second generation youth adopted American sport forms, and some became national heroes in contrast to the stereotype of Italian gangsters. By the 1950s Italians had become icons of popular culture, yet negative stereotypes persisted and assimilation remained fragmented. 展开更多

Background: The influence of self-presentation concerns on the adolescent sport experience has received scant empirical attention. The purpose of this investigation was to prospectively examine the relationship among self-presentational concerns and pre-game affective states among middle and high school aged football players. Methods: American football players (n = 112; mean age = 15.57 years) completed a measure of self-presentational concerns (SPSQ, McGowan, et al., 2008) a week prior to the measurement of selected pre-game affective states (i.e., attentiveness, self-assurance, serenity, and fear). Results: Regression analyses revealed that concerns about appearing athletically untalented negatively contributed to the significant prediction (p 〈 0.001) of pre-game attentiveness, /3 = -0.43, Radj ^2 19.5% (p 〈 0.001), and self-assurance, /3 = -0.38, R^dj = 11.9% (p 〈 0.01). Conclusion: These findings highlight the importance of reducing self-presentational concerns in promoting positive pre-game mental states that likely impact the quality of athletes' competitive play and experience.

Compact molecular packing with short π-π stacking and large π-overlap in organic semiconductors is desirable for efficient charge transport and high carrier mobility. Thus charge transport anisotropy along different directions is commonly observed in organic semiconductors. Interestingly, in this article, we found that comparable charge transport property were achieved based on the single crystals of a bis-fused tetrathiafulvalene derivative (EM-TTP) compound along two interaction directions, that is, the multiple strong S…S intermolecular interactions and the π-π stacking direction, with the measured electrical conductivity and hole mobility of 0.4 S cm-1, 0.94 cm2 V i s 1 and 0.2 S cm-1, 0.65 cm2 V-1 s-1, respectively. This finding provides us a new molecular design concept for developing novel organic semiconductors with isotropic charge transport property through the synergistic effect of multiple intermolecular interactions (such as π-π interactions) and π-π stacking. 展开更多
