  1. Interference of Overlapping Insect Vibratory Communication Signals: An Eushistus heros Model.

    Directory of Open Access Journals (Sweden)

    Andrej Čokl

    Full Text Available Plants limit the range of insect substrate-borne vibratory communication by their architecture and mechanical properties that change transmitted signal time, amplitude and frequency characteristics. Stinkbugs gain higher signal-to-noise ratio and increase communication distance by emitting narrowband low frequency vibratory signals that are tuned with transmission properties of plants. The objective of the present study was to investigate hitherto overlooked consequences of duetting with mutually overlapped narrowband vibratory signals. The overlapped vibrations of the model stinkbug species Eushistus heros, produced naturally or induced artificially on different plants, have been analysed. They represent female and male strategies to preserve information within a complex masked signal. The brown stinkbugs E. heros communicate with species and gender specific vibratory signals that constitute characteristic duets in the calling, courtship and rivalry phases of mating behaviour. The calling female pulse overlaps the male vibratory response when the latency of the latter is shorter than the duration of the female triggering signal or when the male response does not inhibit the following female pulse. Overlapping of signals induces interference that changes their amplitude pattern to a sequence of regularly repeated pulses in which their duration and the difference between frequencies of overlapped vibrations are related inversely. Interference does not occur in overlapped narrow band female calling pulses and broadband male courtship pulse trains. In a duet with overlapped signals females and males change time parameters and increase the frequency difference between signals by changing the frequency level and frequency modulation pattern of their calls.

    Boxenhorn, Burton; Greiff, Paul

    A novel vibratory micromechanical gyro with an active area less than one millimeter square has been analyzed, designed, and built. It has been demonstrated that such a gyro can be built using semiconductor fabrication techniques, and that the resulting performance is reasonably predictable. Further improvement of this gyro will result in an instrument that is small, low power, and in particular, will be very cheap in large quantitites.

    Dalma Martinovic-Weigelt

    Full Text Available Chemical structures of several urinary reproductive pheromones in fish have been identified, and their role in the chemical communication of reproductive condition is well characterized. On the contrary, the role of chemical communication in signalling of social/territorial status in fish is poorly understood. Fathead minnows are an example of a fish species whose life history traits appear conducive to evolution of chemical communication systems that confer information about social/territorial status. Male reproduction in this species is dependent upon their ability to acquire and defend a high quality nesting territory, and to attract a female to the nest. We hypothesized that fathead minnow males use visual and urine-derived chemical cues to signal territorial status. To test this hypothesis, effects of territorial acquisition on male-specific secondary sex characteristics (SSCs and urine volumes were first assessed. Second, frequencies of male urination in varying social contexts were examined. Finally, nuclear magnetic resonance-based metabolomics was used to identify urinary metabolites that were differentially excreted in the urine of territorial versus non-territorial males. The expression of SSCs, sperm, and urine volumes increased with territory acquisition, and either remained unchanged or decreased in non-territorial males. Frequency of male urination increased significantly in the presence of females (but not males, suggesting that females are the main target of the urinary signals. Territorial and non-territorial males had distinct urinary metabolomic profiles. An unforeseen finding was that one could discern future territorial status of males, based on their initial metabolomic profiles.

    1993-01-01

    Prototypes of a piezo-electric vibratory angular rate transducer (gyroscope) (PVG) have been constructed and evaluated. The construction is on the lines suggested by Burdess. The sensitive element is a cylinder of radially poled piezo-electric ceramic. The cylinder is metallized inside and out, and the outer metallization is divided into eight electrodes. The metallization on the inside is earthed. A phase locked loop, using pairs of the electrodes, causes the cylinder to vibrate in one of its two fundamental, degenerate modes. In the presence of rotation, some of the vibration is coupled into the outer mode. This can be detected, or suppressed with a closed-up technique and provides a measure of rotation rate. The gyroscope provides a number of advantages over rotating mass and optical instruments: low size and mass, lower power consumption, potentially high reliability, potentially good dormancy, low cost and high maximum rate.

  12. Characterization of the Bell-Shaped Vibratory Angular Rate Gyro

    Full Text Available The bell-shaped vibratory angular rate gyro (abbreviated as BVG is a novel shell vibratory gyroscope, which is inspired by the Chinese traditional bell. It sensitizes angular velocity through the standing wave precession effect. The bell-shaped resonator is a core component of the BVG and looks like the millimeter-grade Chinese traditional bell, such as QianLong Bell and Yongle Bell. It is made of Ni43CrTi, which is a constant modulus alloy. The exciting element, control element and detection element are uniformly distributed and attached to the resonator, respectively. This work presents the design, analysis and experimentation on the BVG. It is most important to analyze the vibratory character of the bell-shaped resonator. The strain equation, internal force and the resonator's equilibrium differential equation are derived in the orthogonal curvilinear coordinate system. When the input angular velocity is existent on the sensitive axis, an analysis of the vibratory character is performed using the theory of thin shells. On this basis, the mode shape function and the simplified second order normal vibration mode dynamical equation are obtained. The coriolis coupling relationship about the primary mode and secondary mode is established. The methods of the signal processing and control loop are presented. Analyzing the impact resistance property of the bell-shaped resonator, which is compared with other shell resonators using the Finite Element Method, demonstrates that BVG has the advantage of a better impact resistance property. A reasonable means of installation and a prototypal gyro are designed. The gyroscopic effect of the BVG is characterized through experiments. Experimental results show that the BVG has not only the advantages of low cost, low power, long work life, high sensitivity, and so on, but, also, of a simple structure and a better impact resistance property for low and medium angular velocity measurements.

    2012-01-01

    Full Text Available We describe different aspects of the reproductive biology, mating behavior, and vibratory communication of the pentatomid Edessa meditabunda (Fabr.. This species shows lower copulation frequency and reproductive potential with longer sexual maturation period compared to other species of pentatomids. Females with multiple mating show increased fecundity when compared with single-mated females and both increased fecundity and reduced longevity when compared with virgin females. Courtship and mating behavior and vibratory signals are typical and similar to what was observed in other species of pentatomids, except that males started the courtship. These results constitute the first paper on biology, behavior, and vibratory communication among species of the subfamily Edessinae.

  14. A hypothetico-deductive approach to assessing the social function of chemical signalling in a non-territorial solitary carnivore.

    Directory of Open Access Journals (Sweden)

    Melanie Clapham

    Full Text Available The function of chemical signalling in non-territorial solitary carnivores is still relatively unclear. Studies on territorial solitary and social carnivores have highlighted odour capability and utility, however the social function of chemical signalling in wild carnivore populations operating dominance hierarchy social systems has received little attention. We monitored scent marking and investigatory behaviour of wild brown bears Ursus arctos, to test multiple hypotheses relating to the social function of chemical signalling. Camera traps were stationed facing bear 'marking trees' to document behaviour by different age sex classes in different seasons. We found evidence to support the hypothesis that adult males utilise chemical signalling to communicate dominance to other males throughout the non-denning period. Adult females did not appear to utilise marking trees to advertise oestrous state during the breeding season. The function of marking by subadult bears is somewhat unclear, but may be related to the behaviour of adult males. Subadults investigated trees more often than they scent marked during the breeding season, which could be a result of an increased risk from adult males. Females with young showed an increase in marking and investigation of trees outside of the breeding season. We propose the hypothesis that females engage their dependent young with marking trees from a young age, at a relatively 'safe' time of year. Memory, experience, and learning at a young age, may all contribute towards odour capabilities in adult bears.

    Falls are a common and devastating problem among elderly people. In a previous study, vibratory insoles were developed to improve postural stability for elderly fallers. To verify the effects of vibratory insoles, a two-stage experiment was conducted to collect center of pressure (COP) signals from 26 elderly fallers and 16 healthy young subjects while standing still. The DFA is used to analyze the behavior of different time-series data obtained from the trajectory of COP. Postural stability was compared by the DFA scaling exponent between a control condition (before using vibratory insoles) and a vibration condition (after using vibratory insoles). For elderly fallers, DFA scaling exponents 95% confidence interval were [1.434, 1.547] and [1.329, 1.451] under control and vibration conditions in the anteroposterior (AP) direction, respectively. The experimental results revealed that temporary stimuli of appropriate amplitude produced by vibration insoles enhanced postural stability in elderly fallers and was more obvious in the AP direction.

    Parametrically disciplined operation of a symmetric nearly degenerate mode vibratory gyroscope is disclosed. A parametrically-disciplined inertial wave gyroscope having a natural oscillation frequency in the neighborhood of a sub-harmonic of an external stable clock reference is produced by driving an electrostatic bias electrode at approximately twice this sub-harmonic frequency to achieve disciplined frequency and phase operation of the resonator. A nearly symmetric parametrically-disciplined inertial wave gyroscope that can oscillate in any transverse direction and has more than one bias electrostatic electrode that can be independently driven at twice its oscillation frequency at an amplitude and phase that disciplines its damping to zero in any vibration direction. In addition, operation of a parametrically-disciplined inertial wave gyroscope is taught in which the precession rate of the driven vibration pattern is digitally disciplined to a prescribed non-zero reference value.

    A bell-shaped vibratory angular velocity gyro (BVG), inspired by the Chinese traditional bell, is a type of axisymmetric shell resonator gyroscope. This paper focuses on development of an error model and compensation of the BVG. A dynamic equation is firstly established, based on a study of the BVG working mechanism. This equation is then used to evaluate the relationship between the angular rate output signal and bell-shaped resonator character, analyze the influence of the main error sources and set up an error model for the BVG. The error sources are classified from the error propagation characteristics, and the compensation method is presented based on the error model. Finally, using the error model and compensation method, the BVG is calibrated experimentally including rough compensation, temperature and bias compensation, scale factor compensation and noise filter. The experimentally obtained bias instability is from 20.5°/h to 4.7°/h, the random walk is from 2.8°/h(1/2) to 0.7°/h(1/2) and the nonlinearity is from 0.2% to 0.03%. Based on the error compensation, it is shown that there is a good linear relationship between the sensing signal and the angular velocity, suggesting that the BVG is a good candidate for the field of low and medium rotational speed measurement.

    The current investigation was carried out to study the effect of vibratory welding technique on mechanical properties of 6 mm thick butt welded mild steel plates. A new concept of vibratory welding technique has been designed and developed which is capable to transfer vibrations, having resonance frequency of 300 Hz, into the molten weld pool before it solidifies during the Shielded metal arc welding (SMAW) process. The important process parameters of vibratory welding technique namely welding current, welding speed and frequency of the vibrations induced in molten weld pool were optimized using Taguchi’s analysis and Response surface methodology (RSM). The effect of process parameters on tensile strength and hardness were evaluated using optimization techniques. Applying RSM, the effect of vibratory welding parameters on tensile strength and hardness were obtained through two separate regression equations. Results showed that, the most influencing factor for the desired tensile strength and hardness is frequency at its resonance value, i.e. 300 Hz. The micro-hardness and microstructures of the vibratory welded joints were studied in detail and compared with those of conventional SMAW joints. Comparatively, uniform and fine grain structure has been found in vibratory welded joints.

  2. Adult Drosophila sensory neurons specify dendritic territories independently of dendritic contacts through the Wnt5-Drl signaling pathway.

    Sensory neurons with common functions are often nonrandomly arranged and form dendritic territories in stereotypic spatial patterns throughout the nervous system, yet molecular mechanisms of how neurons specify dendritic territories remain largely unknown. In Drosophila larvae, dendrites of class IV sensory (C4da) neurons completely but nonredundantly cover the whole epidermis, and the boundaries of these tiled dendritic fields are specified through repulsive interactions between homotypic dendrites. Here we report that, unlike the larval C4da neurons, adult C4da neurons rely on both dendritic repulsive interactions and external positional cues to delimit the boundaries of their dendritic fields. We identify Wnt5 derived from sternites, the ventral-most part of the adult abdominal epidermis, as the critical determinant for the ventral boundaries. Further genetic data indicate that Wnt5 promotes dendrite termination on the periphery of sternites through the Ryk receptor family kinase Derailed (Drl) and the Rho GTPase guanine nucleotide exchange factor Trio in C4da neurons. Our findings thus uncover the dendritic contact-independent mechanism that is required for dendritic boundary specification and suggest that combinatory actions of the dendritic contact-dependent and -independent mechanisms may ensure appropriate dendritic territories of a given neuron. © 2015 Yasunaga et al.; Published by Cold Spring Harbor Laboratory Press.

    2017-10-11

    This paper presents a theoretical analysis of mechanical and electrical noise in the sense channel of micro-electromechanical systems (MEMS) vibratory gyroscopes. Closed-form expressions for the power spectral density (PSD) of the noise equivalent rate (NER) of gyroscopes in the open-loop and the force-rebalance operations are derived by using an averaged PSD model and an equivalent transfer function. The obtained expressions are verified through numerical simulations, demonstrating close agreements between the analytic and the numerical models. Based on the derived expressions for the PSD of the NER, the impacts of the modal frequency split, quality factor, and the gain of the feedback forcer, as well as the gain of the signal conditioning circuit, on the gyroscope noise characteristics are theoretically analyzed. In addition, the angle random walk (ARW) and the standard deviation of the NER are also discussed through the PSD models. Finally, the effects of the loop closing, the mode matching, and the gain of the feedback forcer on the PSD of the NER were verified via a MEMS vibratory gyroscope with a tunable modal frequency split.

  9. A novel oscillation control for MEMS vibratory gyroscopes using a modified electromechanical amplitude modulation technique

    Ma, Wei; Lin, Yiyu; Liu, Siqi; Zheng, Xudong; Jin, Zhonghe

    2017-02-01

    This paper reports a novel oscillation control algorithm for MEMS vibratory gyroscopes using a modified electromechanical amplitude modulation (MEAM) technique, which enhances the robustness against the frequency variation of the driving mode, compared to the conventional EAM (CEAM) scheme. In this approach, the carrier voltage exerted on the proof mass is frequency-modulated by the drive resonant frequency. Accordingly, the pick-up signal from the interface circuit involves a constant-frequency component that contains the amplitude and phase information of the vibration displacement. In other words, this informational detection signal is independent of the mechanical resonant frequency, which varies due to different batches, imprecise micro-fabrication and changing environmental temperature. In this paper, the automatic gain control loop together with the phase-locked loop are simultaneously analyzed using the averaging method and Routh-Hurwitz criterion, deriving the stability condition and the parameter optimization rules of the transient response. Then, a simulation model based on the real system is set up to evaluate the control algorithm. Further, the proposed MEAM method is tested using a field-programmable-gate-array based digital platform on a capacitive vibratory gyroscope. By optimizing the control parameters, the transient response of the drive amplitude reveals a settling time of 45.2 ms without overshoot, according well with the theoretical prediction and simulation results. The first measurement results show that the amplitude variance of the drive displacement is 12 ppm in an hour while the phase standard deviation is as low as 0.0004°. The mode-split gyroscope operating under atmospheric pressure demonstrates an outstanding performance. By virtue of the proposed MEAM method, the bias instability and angle random walk are measured to be 0.9° h-1 (improved by 2.4 times compared to the CEAM method) and 0.068° (√h)-1 (improved by 1.4 times

  12. Field Tests to Investigate the Penetration Rate of Piles Driven by Vibratory Installation

    Directory of Open Access Journals (Sweden)

    Zhaohui Qin

    2017-01-01

    Full Text Available Factors directly affecting the penetration rate of piles installed by vibratory driving technique are summarized and classified into seven aspects which are driving force, resistance, vibratory amplitude, energy consumption, speeding up at the beginning, pile plumbness keeping, and slowing down at the end, from the mechanism and engineering practice of the vibratory pile driving. In order to find out how these factors affect the penetration rate of the pile in three major actors of vibratory pile driving: (i the pile to be driven, (ii the selected driving system, and (iii the imposed soil conditions, field tests on steel sheet piles driven by vibratory driving technique in different soil conditions are conducted. The penetration rates of three different sheet pile types having up to four different lengths installed using two different vibratory driving systems are documented. Piles with different lengths and types driven with or without clutch have different penetration rates. The working parameters of vibratory hammer, such as driving force and vibratory amplitude, have great influences on the penetration rate of the pile, especially at the later stages of the sinking process. Penetration rate of piles driven in different soil conditions is uniform because of the different penetration resistance including shaft friction and toe resistance.

    2017-09-01

    This paper presents a self-powered wireless alarming sensor node (SWASN), which was designed to monitor the occurrence of concerning vibratory events. The major components of the sensor node include a vibration-threshold-triggered energy harvester (VTTEH) that powers the sensor node, a dual threshold voltage control circuit (DTVCC) for power management and a radio frequency (RF) signal transmitting module. The VTTEH generates significant electric energy only when the input vibration reaches certain amplitude. Thus, the VTTEH serves as both the power source and the vibration-event-sensing element for the sensor node. The DTVCC was specifically designed to utilize the limited power supply from the VTTEH to operate the sensor node. Constructed with only voltage detectors and MOSFETs, the DTVCC achieved low power consumption, which was 65% lower compared with the power management circuit designed in our previous work. Meanwhile, a RF transmit circuit was constructed based on the commercially available CC1110-F32 wireless transceiver chip and a compact planar antenna was designed to improve the signal transmission distance. The sensor node was fabricated and was characterized both in the laboratory and in the field. Experimental results showed that the SWASN could automatically send out alarming signals when the simulated concerning event occurred. The waiting time between two consecutive transmission periods is less than 125 s and the transmission distance can reach 1.31 km. The SWASN will have broad applications in field surveillances.

    This paper presents an adaptive control algorithm for realizing a vibratory angle measuring gyroscope so that rotation angle can be directly measured without integration of angular rate, thus eliminating the accumulation of numerical integration errors. The proposed control algorithm uses a trajectory following approach and the reference trajectory is generated by an ideal angle measuring gyroscope driven by the estimate of angular rate and the auxiliary sinusoidal input so that the persistent excitation condition is satisfied. The developed control algorithm can compensate for all types of fabrication imperfections such as coupled damping and stiffness, and mismatched stiffness and un-equal damping term in an on-line fashion. The simulation results show the feasibility and effectiveness of the developed control algorithm that is capable of directly measuring rotation angle without the integration of angular rate.

  15. Climate Change and Some Other Implications of Vibratory Existence

    Full Text Available Modern Process Philosophy began when Alfred North Whitehead realized that existence is primarily vibratory, not points but processes. Vibrations are best understood as sound waves, or through using auditory metaphors rather than visual ones. Our Universe is more like music than matter, but how does this help us better understand it? In this paper I use the example of the large ocean current oscillators that help drive our climate systems to reveal the more effective nature of auditory approaches. Through an auditory approach, we can better understand the ways these oscillations constrain and interact with other levels of oscillations as well as how they might be destroyed by other levels. This can then lead to us extending our ethics to the conservation of these oscillations.

    Full Text Available The paper presents the results of numerical calculations, with the finite element method in the ABAQUS program environment, of the vibratory shot peening process with loose peening elements. The behaviour of shot peening elements was analysed in the kinematic aspect. The impact of the initial deployment of vibratory shot peening elements on their behaviour during processing was investigated, including the displacement, velocity, acceleration and the number of collisions. The way of determining the effectiveness of the processing with the vibratory shot peening was illustrated.

    Full Text Available The current exigencies that a territory must faced in order to its’ optimalpositioning in future regional competition requires the ability to design theappropriate mechanism which better valorize the territory capability. Such aconstruct is vital for territorial sustainable development and supposes thecreation of a specific body of knowledge from distinctive local resourceexploitation and unique value creation and allocation. Territorial mechanismdesign is a typical management decision about identification, ownership andcontrol of specific strategic capabilities and their combination in a distinctiveterritorial portfolio. The most difficult responsibility is to allocate the territorialvalue added which is a source of conflict among territorial components. Ourcurrent paper research covers the basics of two complementary territorialpillars-rural and tourism potential and proves the lack of specific designmechanisms which explain the current diminishing value of Galati Brailaregion. The proposed management system, relying upon territorial controlmechanism, will ensure knowledge sharing process via collaborative learning,with the final role of appropriate territorial attractivity signals, reinforcingidentity as key factor of territorial attractability.

    We compared semen quality and patient preference between penile vibratory stimulation and electroejaculation in spinal cord injured men. We treated 11 spinal cord injured men with penile vibratory stimulation and electroejaculation in random order. End points examined were semen analysis, sperm functional assessment, and patient pain scores (1 to 10) and preferred procedure. Differences between the procedures were determined with the paired Student t test. There was no difference in antegrade sperm count but penile vibratory stimulation specimens had greater motility (26.0 versus 10.7%), viability (25.2 versus 9.7%) and motile sperm count (185.0 x 10(6) versus 97.0 x 10(6)). The retrograde sperm count was greater (but not significant) in electroejaculation patients. The total (antegrade plus retrograde) and motile sperm counts were not different. There was no difference in immunobead test (all negative), cervical mucus penetration or sperm penetration assay, although the percent hamster egg penetration approached significance (53.7% for penile vibratory stimulation versus 22.1% for electroejaculation, p = 0.06). There was no difference in the peak blood pressures and no complications were noted. Pain scores were significantly greater for electroejaculation compared to penile vibratory stimulation (5.2 versus 1.7, respectively). All patients preferred penile vibratory stimulation. There was a slight advantage in sperm quality and a high patient preference in favor of penile vibratory stimulation. Penile vibratory stimulation should be attempted first to induce ejaculation in spinal cord injured men, with electroejaculation reserved for failures.

    We investigate internal and external sphincter responses during penile vibratory stimulation and electroejaculation in men with spinal cord injury. Ejaculation induction with simultaneous recording of external and internal sphincter pressures was performed in 9 spinal cord injured men. Of the patients with upper motor neuron lesions 3 underwent penile vibratory stimulation and 3 underwent electroejaculation. In 3 men who did not respond to PVS, including 1 with upper motor neuron and 2 with lower motor neuron lesions, penile vibratory stimulation and subsequent electroejaculation were performed. In successful penile vibratory stimulation and electroejaculation upper motor neuron cases external sphincter pressure first reached a peak (average 180 cm. H2O) and subsequently decrease followed in 3 to 10 seconds by a peak in internal sphincter pressure (average 178 cm. H2O), which exceeded external sphincter pressure and ejaculation occurred. During electroejaculation, the pattern progressed, despite complete discontinuation of electrical stimulation. In electroejaculation, there was a trend for a more rapid return of external sphincter pressure greater than internal sphincter pressure, which may explain the electroejaculation retrograde fraction. In nonresponders external sphincter pressure never increased to more than 105 cm. H2O in response to penile vibratory stimulation and no ejaculation was induced. In nonresponders to penile vibratory stimulation, electroejaculation induced a typical sustained increase in internal sphincter pressure and external sphincter pressure but at lower peak pressures. Forceful contraction of the external sphincter followed by contraction of the internal sphincter always precedes ejaculation during electroejaculation and penile vibratory stimulation. Similarities between penile vibratory stimulation and electroejaculation suggest that the latter induces ejaculation via a complex neurological pathway rather than by simple direct end organ

    2009-08-11

    Vibration therapy is currently used in diverse medical specialties ranging from orthopedics to urology to sports medicine. The celebrated 19th-century neurologist, J.-M. Charcot, used vibratory therapy to treat Parkinson disease (PD). This study analyzed printed writings by Charcot and other writers on vibratory therapy and accessed unpublished notes from the Salpêtrière Hospital, Paris. Charcot lectured on several occasions on vibratory therapy and its neurologic applications. He developed a vibration chair for patients with PD after he observed that patients were more comfortable and slept better after a train or carriage ride. He replicated this experience by having patients undergo daily 30-minute sessions in the automated vibratory chair (fauteuil trépidant). His junior colleague, Gilles de la Tourette, extended these observations and developed a helmet that vibrated the head on the premise that the brain responded directly to the pulsations. Although after Charcot's death vibratory therapy was not widely pursued, vibratory appliances are reemerging in 21st century medicine and can be retested using adaptations of Charcot's neurologic protocols.

    A high proportion of the geriatric population suffers from presbylaryngis and presbyphonia; however, our knowledge of vibratory patterns in this population is almost nonexistent. In this study, we investigate the vocal fold vibratory patterns of healthy elderly females to determine which features or combination of them could best describe the geriatric voices. Cross-sectional study with 20 elderly healthy females with no history of voice problems. Hilbert transformed glottal area waveforms (GAWs) from serial high-speed digital imaging of sustained phonation are used to provide quantitative measures of glottal vibratory characteristics and perturbations; open quotient, jitter, and shimmer. Nyquist plots provide interpretable patterns to portray the vibratory characteristics as clear, pressed, breathy, and atypical patterns. The GAW from most elderly speakers (50%) showed vibratory characteristics associated with a more pressed voice and higher glottal perturbation values: their Nyquist plot patterns show wide scatterings around the rim of the plot reflecting a much-reduced ability in sustaining vibratory oscillation; these were distinct differences from previously reported data on younger speakers. Qualitative examination revealed more anteriorly placed glottal gaps in the geriatric females. These findings have important implications in understanding voice production in the geriatric population and in helping to establish normal perturbation references among female speakers across age.

    Most spinal cord injured men require assisted ejaculation procedures to obtain semen, and the majority can achieve this result by vibratory stimulation or electroejaculation. We determined if semen obtained by vibratory stimulation differed in quality from that obtained by electroejaculation. Between subjects and within subjects designs were used. Of 77 spinal cord injured men 23 underwent vibratory stimulation only, 44 electroejaculation only and 10 both procedures. Antegrade, retrograde and total ejaculates were analyzed in each subject for total sperm count, percent motile sperm and percent sperm with rapid linear motion. With vibratory stimulation compared to electroejaculation the percent motile sperm and percent sperm with rapid linear motion were significantly greater, whereas total sperm count was similar, in the antegrade specimens and total ejaculates. This finding was true for different groups of subjects as well as within a group of the same subjects. Semen obtained by vibratory stimulation is of better quality than that obtained by electroejaculation. In medical practices that include assisted ejaculation of spinal cord injured men, we recommend obtaining a specimen by vibratory stimulation. If that method fails electroejaculation should be performed.

    The present invention relates to devices for taking sediment cores from the ocean floor. It consists in a vibratory device, comprising a string of pipe, a vibrator disposed on the string of pipe for sinking the pipe into the ocean floor, an arrangement for providing for periodical engagement and disengagement of the vibrator with the string of pipe, a hoist providing for periodical displacement of the vibrator, which is originally disposed on the lower portion of the string of pipe, up the string as the latter is being sunk into the ocean floor, and operatively coupled with the engaging arrangement. A piston is freely displaceable in the string of pipe and fixed relative to the ocean floor when the pipe is being sunk, to retain the ocean floor sediments in the pipe. The core of sediment is pressed against the piston under the action of hydrostatic and atmospheric pressures. A system is provided for stabilizing the device consisting of a load platform, a float, and guide cables. (6 claims)

  5. Animal interactions and the emergence of territoriality.

    Directory of Open Access Journals (Sweden)

    Luca Giuggioli

    2011-03-01

    Full Text Available Inferring the role of interactions in territorial animals relies upon accurate recordings of the behaviour of neighbouring individuals. Such accurate recordings are rarely available from field studies. As a result, quantification of the interaction mechanisms has often relied upon theoretical approaches, which hitherto have been limited to comparisons of macroscopic population-level predictions from un-tested interaction models. Here we present a quantitative framework that possesses a microscopic testable hypothesis on the mechanism of conspecific avoidance mediated by olfactory signals in the form of scent marks. We find that the key parameters controlling territoriality are two: the average territory size, i.e. the inverse of the population density, and the time span during which animal scent marks remain active. Since permanent monitoring of a territorial border is not possible, scent marks need to function in the temporary absence of the resident. As chemical signals carried by the scent only last a finite amount of time, each animal needs to revisit territorial boundaries frequently and refresh its own scent marks in order to deter possible intruders. The size of the territory an animal can maintain is thus proportional to the time necessary for an animal to move between its own territorial boundaries. By using an agent-based model to take into account the possible spatio-temporal movement trajectories of individual animals, we show that the emerging territories are the result of a form of collective animal movement where, different to shoaling, flocking or herding, interactions are highly heterogeneous in space and time. The applicability of our hypothesis has been tested with a prototypical territorial animal, the red fox (Vulpes vulpes.

    The objective of this calculation is twofold. First, to determine whether or not separation of interlocking drip shield (DS) segments occurs during vibratory ground motion. Second, if DS separation does not occur, to estimate the area of the DS for which the residual 1st principal stress exceeds a certain limit. (The area of DS plate-1 and DS plate-2 [see Attachment I] where the residual 1st principal stress exceeds a certain limit will be, for brevity, referred to as ''the damaged area'' throughout this document; also, DS plate-1 and DS plate-2 will be referred to, for brevity, as ''DS plates'' henceforth.) The stress limit used throughout this document is defined as 50 percent of yield strength of the DS plate material, Titanium Grade 7 (Ti-7) (SB-265 R52400), at temperature of 150 C. A set of 15 calculations is performed at two different annual frequencies of occurrence (annual exceedance frequency): 10{sup -6} per year (1/yr) and 10{sup -7} 1/yr . (Note: Due to computational problems only five realizations at 10{sup -7} 1/yr are presented in this document.) Additionally, one calculation is performed at the annual frequency of occurrence of 5 {center_dot} 10{sup -4} 1/yr. The scope of this document is limited to reporting whether or not the DS separation occurs. If the DS separation does not occur the scope is limited to reporting the calculation results in terms of the damaged area. All these results are evaluated for the DS plates. This calculation is intended for use in support of the Total System Performance Assessment-License Application seismicity modeling. This calculation is associated with the DS design and was performed by the Waste Package Design group. AP-3.12Q, ''Design Calculations and Analyses'' (Ref. 1) is used to perform the calculation and develop the document. The DS is classified as Quality Level 1 (Ref. 5, p. 7). Therefore, this calculation is subject to the Quality Assurance

    Vibratory pile drivers, used for marine construction, can produce sustained, high sound pressure levels (SPLs) in areas that overlap with dolphin habitats. Dolphins rely on echolocation for navigation, detecting predators and prey, and to coordinate group behavior. This study examined the effects of vibratory pile driver noise on dolphin sustained target detection capabilities through echolocation. Five dolphins were required to scan their enclosure and indicate the occurrences of phantom echoes during five different source levels of vibratory pile driver playback sound (no-playback control, 110, 120, 130, and 140 dB re 1 μPa). Three of the dolphins demonstrated a significant decrease in target detection performance at 140 dB playback level that was associated with an almost complete secession of echolocation activity. The performance of two dolphins was not affected. All dolphins rapidly returned to baseline levels of target detection performance by their second replication. However, an increased number of clicks was produced at the highest playback SPL. The data suggest that the decrease in vigilant behavior was due to the vibratory pile driver noise distracting the dolphins and decreasing their motivation to perform the task.

    OBJECTIVES To evaluate the effectiveness of penile vibratory stimulation for the management of retarded orgasm. Retarded orgasm, a condition characterized by difficulty achieving orgasm and ejaculation, is one of the most recalcitrant of the male sexual dysfunctions. Currently, no evidence-based treatments have been proven to ameliorate this condition. METHODS Men who had a complete inability to achieve an orgasm during sexual relations in the previous 3 months were instructed in the use of penile vibratory stimulation. The men’s responses were measured by self-report of orgasm function and using the orgasm and satisfaction domains of the International Index of Erectile Function. The responses were assessed at baseline (admission into the study) and at 3 and 6 months. RESULTS A total of 36 men met the inclusion criteria, and 72% reported the restoration of orgasm. These responders reported that orgasm during sexual relations occurred 62% of the time. A statistically and clinically significant increase occurred in the orgasm and satisfaction domains of the International Index of Erectile Function between the baseline visit and the 3-month follow-up visit. These gains were sustained at 6 months. CONCLUSIONS Penile vibratory stimulation is an effective treatment for retarded orgasm. Penile vibratory stimulation should be integrated into current cognitive-behavioral sex therapy techniques to achieve maximal effectiveness and satisfaction. PMID:17382163

  1. Control of Vibratory Energy Harvesters in the Presence of Nonlinearities and Power-Flow Constraints

    Science.gov (United States)

    Cassidy, Ian L.

    Over the past decade, a significant amount of research activity has been devoted to developing electromechanical systems that can convert ambient mechanical vibrations into usable electric power. Such systems, referred to as vibratory energy harvesters, have a number of useful of applications, ranging in scale from self-powered wireless sensors for structural health monitoring in bridges and buildings to energy harvesting from ocean waves. One of the most challenging aspects of this technology concerns the efficient extraction and transmission of power from transducer to storage. Maximizing the rate of power extraction from vibratory energy harvesters is further complicated by the stochastic nature of the disturbance. The primary purpose of this dissertation is to develop feedback control algorithms which optimize the average power generated from stochastically-excited vibratory energy harvesters. This dissertation will illustrate the performance of various controllers using two vibratory energy harvesting systems: an electromagnetic transducer embedded within a flexible structure, and a piezoelectric bimorph cantilever beam. Compared with piezoelectric systems, large-scale electromagnetic systems have received much less attention in the literature despite their ability to generate power at the watt--kilowatt scale. Motivated by this observation, the first part of this dissertation focuses on developing an experimentally validated predictive model of an actively controlled electromagnetic transducer. Following this experimental analysis, linear-quadratic-Gaussian control theory is used to compute unconstrained state feedback controllers for two ideal vibratory energy harvesting systems. This theory is then augmented to account for competing objectives, nonlinearities in the harvester dynamics, and non-quadratic transmission loss models in the electronics. In many vibratory energy harvesting applications, employing a bi-directional power electronic drive to actively

    Submicron bovine hydroxyapatite was obtained for rapid prototyping. Hydroxyapatite structure originated from bovine mineral bone has great importance among the biomaterials and biocompatibility due to its great similarity with the human bone structure. This study aims to obtain powder for manufacture by rapid prototyping of scaffolds. This technique manufacture requires highly reactive powders to compensate for the absence of pressure forming. Hydroxyapatite was milled in a ball mill and vibratory mill, and analyzed for their average equivalent spherical diameter and surface area. Test specimens were isostatically pressed at 100 MPa and machined into cylindrical test specimens. These specimens were sintered at several temperatures to determine the optimal sintering temperature based on densification and chemistry stability. In grinding ball mill was obtained particles of equivalent diameter of 0.74 micron in vibratory mill of 0.46 micrometers. An average flexural strength of 100 MPa and 99,8% of real density was attained for the sample sintered at 1300 deg C/2h, signaling potential for use in rapid prototyping. (author)

    Full Text Available Each historial period can be seen as a socio-spatial order, a moment in the socio-spatial formation which requires an analysis (more and more complex every day of two important dimensions. First of all, we can analyze what is there, the existence of the territory used, the territory as it is used today from an articulation of the key variables of the time; that is to say, the so-called techno-science complex, with the information and financial contents as well. These variables reveal the hegemonic spatial facade, and their analysis shows how territory works. Secondly, we should pay attention to movement; that is, how the territory is being used and how it could be used. In other words, we should take a look at the possibilities offered by the historical context we are immersed in, which may or may not come true. The scientifically and technically named present state, whose dynamics answers to the totalitarianism of information and finance, can also be the result of other possibilities and combinations which start to come up timidly as ways of life and work.

  7. IMPACT OF VIBRATORY AND ROTATIONAL SHOT PEENING ONTO SELECTED PROPERTIES OF TITANIUM ALLOY SURFACE LAYER

    Full Text Available This study presents the results of tests on impact of vibratory and rotational shot peening of the Ti6A12Mo2Cr titanium alloy onto the processed object surface roughness and surface layer microhardness. The external surfaces of ring-shaped samples were shot peened. The preceding process consisted of turning with a cubic boron nitride blade knife. Steel beads, having a diameter of 6 mm, were used as a processing medium. The variable parameters of shot peening were vibrator amplitude and shot peening time. The range of recommended technological parameters for vibratory and rotational shot peening was determined. As a result of shot peening, the surface roughness could be reduced by approximately 4 times and the surface layer could be hardened to the depth of approximately 0.4 mm.

  8. Vibratory-compacted (vipac/sphere-pac) nuclear fuels - a comparison with pelletized nuclear fuels

    In order to achieve the packing densities required for nuclear fuel stability, economy and performance, the fuel material must be densified. This has traditionally been performed by high-temperature sintering. (At one time, fuel densification was investigated using cold/hot swaging. However, this fabrication method has become uncommon.) Alternatively, fuel can be densified by vibratory compaction (VIPAC). During the late 1950's and into the 1970's, in the U.S., vibratory compaction fuel was fabricated and test irradiated to evaluate its applicability compared to the more traditional pelletized fuel for nuclear reactors. These activities were primarily focused on light water reactors (LWR) but some work was performed for fast reactors. This paper attempts to summarize these evaluations and proposes to reconsider VIPAC fuel for future use. (author)

    Invasive and noninvasive diagnostic testing was correlated in 11 patients with acute compartmental syndromes of the forearm. The excellent correlation between diminished perception of vibration and increasing compartmental pressure suggested that 256 cycle per second (cps) vibratory stimuli may be useful clinically in determining the appropriate time for surgical intervention in the acute compartmental syndrome. In 12 adult male volunteers, elevated compartment pressures were created in the anterior tibial compartment of the leg. A decrease in perception to 256 cycle per second (cps) vibratory stimulus was the earliest sensory abnormality to occur with elevated tissue compartment pressures. Analysis of variance showed significantly that 256-cps vibration was the most reliable and earliest sensory modality to change at pressures of 35 to 40 mmHg. These clinical and experimental findings support the use of the 256-cps tuning fork as a noninvasive diagnostic test in the evaluation of the patient with suspected acute compartment syndrome.

    A theoretical and experimental study was made of the conveying speed with which granular materials are transported by vibratory conveyors. The basic assumption made is that the layer of granular material can be considered as a point mass. The theory incorporates rest, slide, and flight phases of the material. Although the emphasis of this study is on the effect of the inclination (and declination) of the conveyor on the conveying speed, the effects of throw number, friction coefficient and vi...

    2017-02-01

    Full Text Available Taking Owen Sheers’s novel, I Saw a Man and its representation of a drone strike in Pakistan’s Federally Administered Tribal Areas as its point of departure, this essay explores three ways in which the killing of an individual from thousands of miles away depends upon a series of screens through which the United States asserts, enacts, and enforces a claim over bodies-in-spaces. These are all nominally technical practices—kill lists; signals intercepts; visual feeds—whose supposed objectivity works to underwrite targeted killing as a rational and reasonable process. But they can each be read instead as part of a political technology that produces and executes ‘killable bodies’. Seen thus, the ‘territory of the screen’ diminishes and even de-materializes the corporeality of the human targets that eventually appear in its sights.

  14. Compensation of Imperfections for Vibratory Gyroscope Systems Using State Observers

    Directory of Open Access Journals (Sweden)

    Chien-Yu CHI

    2009-08-01

    Full Text Available This paper presents a novel approach that can compensate errors resulting from the imperfections of mechanical structures and interface circuits for MEMS gyroscope systems. Different from most of existing researches on gyroscopes wherein the mechanical structure and interface circuit are either assumed to be ideal or optimized individually, this approach uses state estimation techniques to compensate all those errors and to obtain correct angular rates in real time. The mechanical structure errors discussed in this paper may come from structure designs and fabrication imperfections. The interface circuit errors include: mismatch of differential capacitors, parasitic capacitance, offset voltage of operation amplifiers, and circuit noise. Simulation results indicates that, with the presence of those errors and a signal-to-noise ratio around 20, the proposed method can measure time-varying angular rates with a bandwidth up to 30 Hz and a sensing accuracy of 1×10-2 rad/sec.

    2016-12-01

    Full Text Available Nation States have three defining characteristics: government of a territory, rapport with a group of people and ownership of a sovereign power. All three of these characteristics are undergoing changes. Several developments involve a redefinition of the “State” and produce numerous contradictions, which can only be solved if we consider the historicity of both the phenomenal essence and the conceptual essence of the State. We need to rethink and reconceptualise the State within the context of the new tendencies and transformations delineated by globalisation.

  17. Vibratory stimulation and rectal probe electroejaculation as therapy for patients with spinal cord injury: semen parameters and pregnancy rates.

    1996-02-01

    The conception rate of patients with spinal cord injuries following penile vibratory stimulation and rectal probe electroejaculation in conjunction with self-insemination, intrauterine insemination or assisted reproductive technique is poorly documented. We reviewed our success rates with penile vibratory stimulation and rectal probe electroejaculation, and the pregnancy rates achieved with self-insemination, intrauterine insemination and assisted reproductive techniques. A total of 78 consecutive patients with spinal cord injuries had a complete neurological examination and was treated initially with penile vibratory stimulation. If unsuccessful, rectal probe electroejaculation was performed to obtain an ejaculate. The ejaculate was then used with self-insemination, intrauterine insemination or assisted reproductive techniques and pregnancies were monitored. Vibratory stimulation was successful in 20 of 37 patients (54%) with a cervical lesion, 14 of 26 (54%) with a lesion at or above T10 and none of 15 when the lesion was below T10. All patients except 2 who elected followup rectal probe electroejaculation had antegrade or retrograde ejaculate. Six patients (7.7%) with extremely poor semen quality were not candidates for assisted fertilization. Of 27 couples who attempted conception 17 were successful (5 self-insemination, 5 intrauterine insemination and 7 assisted reproductive techniques). Penile vibratory stimulation should be used as first line therapy in patients with lesions above T10 while rectal probe electroejaculation should be considered as a second option. Motivated patients can achieve success with self-insemination, intrauterine insemination and assisted reproductive techniques.

  18. Territory: An Unknown Quantity in Debates on Territorial Cohesion

    Directory of Open Access Journals (Sweden)

    Andreas Faludi

    2013-08-01

    Full Text Available There are complaints about territorial cohesion being a vague concept, but in relevant debates territory, too, figures as an unknown quantity. Thus, is it the fixed property of any state, region or local administrative unit, or is it a malleable social construct; rather than being filled with bounded territories, does space overall contain a dynamic network with fuzzy internal, as well as external boundaries, with implications for territorial cohesion? After all, if the former were to be true, territorial cohesion would refer to qualities of what is inside bounded territories. If it were to be the latter, then the meaning of territorial cohesion would include qualities of the relations within a complex network of socially constructed, sometimes ephemeral constructs. There are implications for the ways subsidiarity and multi-level governance are invoked in EU discourse where there is a similar failure to question the underlying notion of territory. What is relevant here is the distinction between a ‘territorial’ and ‘relational’ geography. Considered opinion suggests that these alternatives can and, in view of the persistence of the principle of territorial representation, must be reconciled. However, though firmly entrenched, some constitutional theorists question the very principle. The debate is far from conclusive but at least it shows that discussion, even of this apparently fundamental principle is possible.

    2013-04-01

    Full Text Available Bell-shaped vibratory angular rate gyro (abbreviated as BVG is a new type Coriolis vibratory gyro that was inspired by Chinese traditional clocks. The resonator fuses based on a variable thickness axisymmetric multicurved surface shell. Its characteristics can directly influence the performance of BVG. The BVG structure not only has capabilities of bearing high overload, high impact and, compared with the tuning fork, vibrating beam, shell and a comb structure, but also a higher frequency to overcome the influence of the disturbance of the exterior environment than the same sized hemispherical resonator gyroscope (HRG and the traditional cylinder vibratory gyroscope. It can be widely applied in high dynamic low precision angular rate measurement occasions. The main work is as follows: the issue mainly analyzes the structure and basic principle, and investigates the bell-shaped resonator’s mathematical model. The reasonable structural parameters are obtained from finite element analysis and an intelligent platform. Using the current solid vibration gyro theory analyzes the structural characteristics and principles of BVG. The bell-shaped resonator is simplified as a paraboloid of the revolution mechanical model, which has a fixed closed end and a free opened end. It obtains the natural frequency and vibration modes based on the theory of elasticity. The structural parameters are obtained from the orthogonal method by the research on the structural parameters of the resonator analysis. It obtains the modal analysis, stress analysis and impact analysis with the chosen parameters. Finally, using the turntable experiment verifies the gyro effect of the BVG.

  20. Predicting vibratory stresses from aero-acoustic loads

    Science.gov (United States)

    Shaw, Matthew D.

    Sonic fatigue has been a concern of jet aircraft engineers for many years. As engines become more powerful, structures become more lightly damped and complex, and materials become lighter, stiffer, and more complicated, the need to understand and predict structural response to aeroacoustic loads becomes more important. Despite decades of research, vibration in panels caused by random pressure loads, such as those found in a supersonic jet, is still difficult to predict. The work in this research improves on current prediction methods in several ways, in particular for the structural response due to wall pressures induced by supersonic turbulent flows. First, solutions are calculated using time-domain input pressure loads that include shock cells and their interaction with turbulent flow. The solutions include both mean (static) and oscillatory components. Second, the time series of stresses are required for many fatigue assessment counting algorithms. To do this, a method is developed to compute time-dependent solutions in the frequency domain. The method is first applied to a single-degree-of-freedom system. The equations of motion are derived and solved in both the frequency domain and the time domain. The pressure input is a random (broadband) signal representative of jet flow. The method is then applied to a simply-supported beam vibrating in flexure using a line of pressure inputs computed with computational fluid dynamics (CFD). A modal summation approach is used to compute structural response. The coupling between the pressure field and the structure, through the joint acceptance, is reviewed and discussed for its application to more complicated structures. Results from the new method and from a direct time domain method are compared for method verification. Because the match is good and the new frequency domain method is faster computationally, it is chosen for use in a more complicated structure. The vibration of a two-dimensional panel loaded by jet

    Full Text Available The identification of the motion of a rigid body by means of linear accelerometers is a problem already investigated by many researchers, but still debated. The optimisation of the number and placement of accelerometers is also another important aspect of the problem. In this study, an experimental procedure is proposed and applied to identify the rigid-body vibratory motion of the steering wheel of a sporting car, by means of six linear accelerometers. Some numerical simulations for investigating possible errors are also presented.

  2. Fundamental understanding, prediction and validation of rotor vibratory loads in steady-level flight

    Science.gov (United States)

    Datta, Anubhav

    This work isolates the physics of aerodynamics and structural dynamics from the helicopter rotor aeromechanics problem, investigates them separately, identifies the prediction deficiencies in each, improves upon them, and couples them back together. The objective is to develop a comprehensive analysis capability for accurate and consistent prediction of rotor vibratory loads in steady level flight. The rotor vibratory loads are the dominant source of helicopter vibration. There are two critical vibration regimes for helicopters in steady level flight: (1) low speed transition and (2) high speed forward flight. The mechanism of rotor vibration at low speed transition is well understood---inter-twinning of blade tip vortices below the rotor disk. The mechanism of rotor vibration at high speed is not clear. The focus in this research is on high speed flight. The goal is to understand the key mechanisms involved and accurately model them. Measured lift, chord force, pitching moment and damper force from the UH-60A Flight Test Program are used to predict, validate and refine the rotor structural dynamics. The prediction errors originate entirely from structural modeling. Once validated, the resultant blade deformations are used to predict and validate aerodynamics. Air loads are calculated using a table look up based unsteady lifting-line model and compared with predictions from a 3-dimensional unsteady CFD model. Both Navier-Stokes and Euler predictions are studied. (Abstract shortened by UMI.) The 3D Navier-Stokes CFD analysis is then consistently coupled with a rotor comprehensive analysis to improve prediction of rotor vibratory loads at high speed. The CFD-comprehensive code coupling is achieved using a loose coupling methodology. The CFD analysis significantly improves section pitching moment prediction near the blade tip, because it captures the steady and unsteady 3D transonic effects. Accurate pitching moments drive elastic twist deformations which together

    2012-09-01

    Full Text Available The paper presents the results of cavitation erosion tests performed on two types of samples. The materials of the samples are frequently used for manufacturing and repairs of the hydro turbines components submitted to cavitation. The first sample was made by welding of an austenitic stainless steel on austenito-feritic base material. The second sample was made similarly with the first but with a martensitic base material. After the welding processes, on both samples was applied a hardening treatment by surface peening. The cavitation erosion tests were performed on vibratory equipment using the indirect method with stationary specimen. The results show a good cavitation erosion resistance on both samples.

    Full Text Available In this paper, we present a method for the determination of the elasticity modulus in the vibratory domain of materials. This approach is based on research and interpretation of the spectrum of natural frequencies resulting from natural vibrations based on the theory of elastic beams. The tests consist of classical tests of longitudinal vibrations of natural composite beams (Aleppo pine wood, long enough to observe some natural frequencies. This identification method showed a good correlation between the theoretical and experimental values, notably the evaluation of the modal parameter for the case of the resonant frequencies and the identification of the modulus of elasticity of the materials used.

    2002-12-01

    The purpose of this review is to present the current understanding of penile vibratory stimulation (PVS) and electroejaculation (EEJ) procedures and its clinical use in men with ejaculatory dysfunction. Unfortunately, the record of treating such individuals has been quite poor, but within recent years development and refinement of PVS and EEJ in men with spinal cord injury (SCI) has significantly enhanced the prospects for treatment of ejaculatory dysfunction. The majority of spinal cord injured men are not able to produce antegrade ejaculation by masturbation or sexual stimulation. However, approximately 80% of all spinal cord injured men with an intact ejaculatory reflex arc (above T10) can obtain antegrade ejaculation with PVS. Electroejaculation may be successful in obtaining ejaculate from men with all types of SCI, including men who do not have major components of the ejaculatory reflex arc. Because vibratory stimulation is very simple in use, non-invasive, it does not require anaesthesia and is preferred by the patients when compared with EEJ, PVS is recommended to be the first choice of treatment in spinal cord injured men. Furthermore, EEJ has been successfully used to induce ejaculation in men with multiple sclerosis and diabetic neuropathy. Any other conditions which affect the ejaculatory mechanism of the central and/or peripheral nervous system including surgical nerve injury may be treated successfully with EEJ. Finally, for sperm retrieval and sperm cryopreservation before intensive anticancer therapy in pubertal boys, PVS and EEJ have been successfully performed in patients who failed to obtain ejaculation by masturbation. Nearly all data concerning semen characteristics in men with ejaculatory dysfuntion originate from spinal cord injured men. Semen analyses demonstrate low sperm motility rates in the majority of spinal cord injured men. The data give evidence of a decline in spermatogenesis and motility of ejaculated spermatozoa shortly after (few

    The resonant shells of vibratory cylinder gyroscopes are commonly packaged in metallic caps. In order to lower the production cost, a portion of vibratory cylinder gyroscopes do not employ vacuum packaging. However, under non-vacuum packaging conditions there can be internal acoustic noise leading to considerable acoustic pressure which is exerted on the resonant shell. Based on the theory of the structural-acoustic coupling, the dynamical behavior of the resonant shell under acoustic pressure is presented in this paper. A finite element (FE) model is introduced to quantitatively analyze the effect of the structural-acoustic coupling. Several main factors, such as sealing cap sizes and degree of vacuum which directly affect the vibration of the resonant shell, are studied. The results indicate that the vibration amplitude and the operating frequency of the resonant shell will be changed when the effect of structural-acoustic coupling is taken into account. In addition, an experiment was set up to study the effect of structural-acoustic coupling on the sensitivity of the gyroscope. A 32.4 mV/°/s increase of the scale factor and a 6.2 Hz variation of the operating frequency were observed when the radial gap size between the resonant shell and the sealing cap was changed from 0.5 mm to 20 mm.

    Full Text Available With an aim to improve the mechanical properties of a weld joint, a new concept of vibratory setup has been designed which is capable to stir the molten weld pool before it solidifies during shielded metal arc welding (SMAW operation. Mechanical vibration having resonance frequency of 300 Hz and amplitude of 0.5 mm was transferred to the molten weld pool of 6 mm thick mild steel butt-welded joints during the welding operation. The experimental work was conducted at various ranges of frequencies, welding current and welding speed. Taguchi's analysis technique has been applied to optimize the process parameters; the response values for analysis are yield strength and micro-hardness. The test results showed that with the application of the vibratory treatment the values of hardness and tensile properties increased. The auxiliary vibrations induced into the weld pool resulted in increased micro-hardness of the weld metal which indicates the orientation of the crystal and refinement of grains took place. This study shows that vibration applied into the weld pool can be successfully improved the mechanical properties of welded joints. Thus this research attempt provided an alternative welding technique for grain refinement of weldments.

    The fertility potential of infertile men can be enhanced to a great extent by the application of assisted reproduction techniques such as intrauterine insemination or in-vitro fertilization with or without intracytoplasmic sperm injection, but how to obtain semen from men with ejaculatory dysfunction remains a problem. The development and refinement of penile vibratory stimulation (PVS) and electroejaculation (EEJ) have significantly brightened the prospects for the treatment of ejaculatory dysfunction. Because vibratory stimulation is non-invasive and easy to perform, and needs no anaesthesia, it is preferred by most of the patients to EEJ, and recommended to be the first choice of treatment for ejaculatory dysfunction.

    2014-11-01

    How do territorial neighbors resolve the location of their boundaries? We addressed this question by testing the predictions of 2 nonexclusive game theoretical models for competitive signaling: the sequential assessment game and the territorial bargaining game. Our study species, the banded wren, is a neotropical nonmigratory songbird living in densely packed territorial neighborhoods. The males possess repertoires of approximately 25 song types that are largely shared between neighbors and sequentially delivered with variable switching rates. Over 3 days, boundary disputes among pairs of neighboring males were synchronously recorded, their perch positions were marked, and their behavioral interactions were noted. For each countersinging interaction between 2 focal males, we quantified approach and retreat order, a variety of song and call patterns, closest approach distance, distance from the territorial center, and female presence. Aggressors produced more rattle-buzz songs during the approaching phase of interactions, whereas defenders overlapped their opponent's songs. During the close phase of the interaction, both males matched frequently, but the key determinant of which one retreated first was song-type diversity-first retreaters sang with a higher diversity. Retreaters also produced more unshared song types during the interaction, and in the retreating phase of the interaction, they overlapped more. A negative correlation between song-type diversity asymmetry and contest duration suggested sequential assessment of motivational asymmetry. The use of this graded signal, which varied with distance from the center and indicated a male's motivation to defend a particular position, supported the bargaining model. The bargaining game could be viewed as a series of sequential assessment contests.

    Gupta, Manoj; Gupta, T C

    2017-10-01

    The present study aims to accurately estimate inertial, physical, and dynamic parameters of human body vibratory model consistent with physical structure of the human body that also replicates its dynamic response. A 13 degree-of-freedom (DOF) lumped parameter model for standing person subjected to support excitation is established. Model parameters are determined from anthropometric measurements, uniform mass density, elastic modulus of individual body segments, and modal damping ratios. Elastic moduli of ellipsoidal body segments are initially estimated by comparing stiffness of spring elements, calculated from a detailed scheme, and values available in literature for same. These values are further optimized by minimizing difference between theoretically calculated platform-to-head transmissibility ratio (TR) and experimental measurements. Modal damping ratios are estimated from experimental transmissibility response using two dominant peaks in the frequency range of 0-25 Hz. From comparison between dynamic response determined form modal analysis and experimental results, a set of elastic moduli for different segments of human body and a novel scheme to determine modal damping ratios from TR plots, are established. Acceptable match between transmissibility values calculated from the vibratory model and experimental measurements for 50th percentile U.S. male, except at very low frequencies, establishes the human body model developed. Also, reasonable agreement obtained between theoretical response curve and experimental response envelop for average Indian male, affirms the technique used for constructing vibratory model of a standing person. Present work attempts to develop effective technique for constructing subject specific damped vibratory model based on its physical measurements.

    Deep boron diffusion often induces residual stress in bulk micromachined MEMS structures, which may affect the MEMS devices operation. In this study, we studied the modal patterns of MEMS vibratory gyroscope under the residual stress (100 – 1000 MPa). Modal patterns and modal frequencies of the gyro are found to be dependent on the residual stress values. Without any residual stress, the modal frequencies drive and sense modeswere found to be 20.06 kHz and 20.36 kHz respectively. In presence of 450 MPa residual stress, the modal frequencies of the drive and sense modes were changed to 42.75 kHz and 43.07 kHz respectively.

    Full Text Available Shear angle and sticking length are two crucial parameters in mechanics of metal cutting. These two parameters directly influence machinability factors such as cutting forces. Thus, shear angle and sticking length were investigated in vibratory turning process by using a pneumatic quick-stop device which was designed and fabricated, in this study. After preparation of ultrasonic assisted turning set-up, experimental tests have been carried out on two types of steel: AISI-1060 and AISI 304. Accordingly, the process of chip formation in each particular cutting test was quickly stopped when deformed chip was still in contact with workpiece. As a result, it was revealed that added linear vibration leads the turning operation to be improved by increase of shear angle and decrease of sticking length. Moreover, the effect of ultrasonic vibration on cutting force and chip micro-hardness is evaluated.

    This paper investigates the properties/formation of combination type resonances of nonlinear conservative/nonconservative distributed parameter vibratory systems subject to external harmonic inputs containing a profusion of frequencies. Overall, this includes the evaluation of simultaneously excited harmonic, sub/superharmonics as well as combination harmonics created by interactions between external and interspectral system frequency branches. Additionally, effort is also given to handling nonconservative characteristics wherein critical damping levels may suppress specific combination harmonics. The foregoing is made possible through the development of a warped and constrained multiple time scales perturbation solution scheme. To illustrate the scheme as well as the nature and form of external and interspectral interaction, a nonlinear nonconservative version of the wave equation which is excited by complex external harmonic fields is given detailed consideration.

    A kind of actuator, which is used in the high frequency Vibratory Stress Relief (VSR), was researched. The actuator is based on the technology of giant magnetostrictive materials. The design principle of the actuator was firstly analyzed, which consists of the analysis of giant magnetostrictive materials and a force generator. Then the design criterion of magnetostrictive actuators was deeply discussed, which includes the dimension design of magnetostrictive materials, the design of magnetic field and the design of elimination of heat. Finally, a real actuator was developed, which has been used in the high frequency VSR. The experimental results show that the developed actuator works very well. Large exciting force but small vibration amplitude will make it widely used in the VSR.

    This article describes the results of theoretical and experimental studies of a vibratory-percussion crusher, which is driven from a pair of self-synchronizing vibration exciters, attached to the shell symmetrically about its vertical axis. In addition to that, crusher’s dynamic model is symmetrical and balanced. Forced oscillation laws for crusher working members and their amplitude-frequency characteristics have been inducted. Domains of existence of synchronous opposite-phase oscillations of crusher working members (crusher’s operating mode) and crusher capabilities have been identified. The results of mechanical and technological tests of a pilot crusher presented in the article show that this crusher may be viewed as an advanced machine for disintegration of supertough materials with minimum regrinding of finished products.

    In present work vibratory synchronization transmission (VST) of a cylindrical roller with dry friction in a vibrating mechanical system excited by two exciters, is studied. Using the average method, the criterion of implementing synchronization of two exciters and that of ensuring VST of a roller, are achieved. The criterion of stability of the synchronous states satisfies the Routh-Hurwitz principle. The influences of the structural parameters of the system to synchronization and stability, are discussed numerically, which can be served as the theoretical foundation for engineering designs. An experiment is carried out, which approximately verify the validity of the theoretical and numerical results, as well as the feasibility of the method used. Utilizing the VST theory of a roller, some types of vibrating crushing or grinding equipments, etc., can be designed.

We are not speaking of a new paradigm, methodology, or a new scholarly theoretical framework, but by contrast, a political change strategy. In this sense we are in front of an instrument that is more ¨social political¨ than ¨technical¨, strictlyspeaking.Given what has already been stated, and the experience of Latin America it is necessary to debate around territorializing policies vs. policies that are territorialized. Two main issues arise, on the one hand, the influence of territory throughout the entire process of local policy making (agenda setting, formulation, implementation,monitoring and evaluation, and what it means to defend ¨territorial sovereignty¨ in articulating strategies.Finally, that the space to go in depth in terms of generation of territorial policies (the raison d etre of a political strategy demands action in multilevel governance (local, regional, national, local economic development and social capital.

    Full Text Available Territorial cohesion is an important target of European Union, constantly promoted by its institutions and their representatives. In the context of the Europe 2020 strategy, one of the most important support documents, the region represents a very important issue, being considered to be the key to its successfulness. The region is seen as a support for the smart growth and all the operational policy concepts try to make use of the spatial potential, by taking better account of the territorial specificities. Two main questions play attention: the need to transform the present-day developmental regions into administrative ones is a priority? What kind of regionalization it must to be promoted? Correlating these issues with already defined territorial cohesion, the administrative region is a real tool for the future territorial development. The experience of the last 14 years asks urgently the building of a new territorial administrative reform, giving competences to regions. For instant, each development region is a construction resulted from a free association of the counties. Their role in the regional development is much reduced one, because their regional councils are not elected; decisions taken at this level are consultative for the social, economical, cultural or political actors.

    The flood's impact during the last twenty years on French territory reveals our lack of preparation towards large-extended floods which might cause the stopping of companies' activity, services, or lead to housing unavailability during several months. New Orleans' case has to exemplify us: four years after the disaster, the city still couldn't get back its dynamism. In France, more than 300 towns are flood-exposed. While these towns are the mainspring of territory's development, it is likely that the majority of them couldn't get up quickly after a large-extended flood. Therefore, to understand and improve the urban territory's resilience facing floods is a real stake for territory's development. Urban technical networks supply, unify and irrigate all urban territories' constituents. Characterizing their flood resilience can be interesting to understand better urban resilience. In this context, waste management during and after floods is completely crucial. During a flood, the waste management network can become dysfunctional (roads cut, waste storage installations or waste treatment flooded). How can the mayor respect his obligation to guarantee salubrity and security in his city? In post flood the question is even more problematic. The waste management network presents a real stake for territory's restart. After a flood, building materials, lopped-of branches, furniture, business stocks, farm stocks, mud, rubbles, animal cadavers are wet, mixed, even polluted by hydrocarbons or toxic substances. The waste's volume can be significant. Sanitary and environmental risks can be crucial. In view of this situation, waste's management in post crisis period raises a real problem. What to make of this waste? How to collect it? Where to stock it? How to process it? Who is responsible? Answering these questions is all the more strategic since this waste is the mark of disaster. Thus, cleaning will be the first population's and local actor's reflex in order to forget the

    Full Text Available Introduction: Vibratory stimulation has been reported as an effective means in reducing the orthodontic pain. The aim of this study was to evaluate the effectiveness of vibratory stimulation from powered-toothbrushes as a noninvasive and nonpharmacological method of reducing pain caused after initial archwire placement and to compare it with other common modalities of management. Materials and Methods: This clinical trial included 75 patients of age 13–25 years, scheduled for fixed mechanotherapy. Patients were divided into five groups: Control, placebo multivitamin, paracetamol, chewing-gum (Cg, and powered-toothbrush. After placement of 0.016″ Nickel Titanium initial archwire (upper/lower in each patient, the discomfort perceived at 2 h, 6 h, bedtime, 24 h, 2 days, 3 days, and 7 days were marked individually using Wong-Baker (0–5 and numeric (0–10 pain rating scales. Kruskal–Wallis test, Friedman test, unpaired t-test were used for statistical analysis. Results: Vibratory stimulation from powered-toothbrushes effectively reduced pain after initial archwire placement. It did not alter the pattern of pain perception, but significantly reduced the overall intensity of pain at each time interval. Cg was not found effective enough to be recommended as a routine treatment modality. Conclusion: Powered-toothbrushes can be recommended as a nonpharmacological and noninvasive substitute for nonsteroidal anti-inflammatory drugs for effective pain reduction in the clinical practice.

  7. Perception of Frequency, Amplitude and Azimuth of a Vibratory Dipole-Source by the Octavolateralis System of Goldfish (Carassius auratus)

    Goldfish (Carassius auratus) were conditioned to suppress respiration to a 40 Hz vibratory source and subsequently tested for stimulus generalization to frequency, stimulus amplitude and position (azimuth). Animals completely failed to generalize to frequencies separated by octave intervals, both lesser and greater than the CS. However they did appear to generalize weakly to an aerial loudspeaker stimulus of the same frequency (40 Hz) after conditioning with an underwater vibratory source. Animals had a gradually decreasing amount of generalization to amplitude changes, suggesting a perceptual dimension of loudness. Animals generalized largely or completely to the same underwater source presented at a range of source azimuths. When these azimuths were presented at a transect of 3 cm, some animals did show decrements in generalization, while others did not. This suggests that although azimuth may be perceived more saliently at distances closer to a dipole source, perception of position is not immediately salient in conditioned vibratory source detection. Differential responding to test stimuli located towards the head or tail suggests the presence of perceptual differences between sources that are rostral or caudal with respect to the position of the animal or perhaps the head.

    Recently, consumer applications have dramatically created the demand for low-cost and compact gyroscopes. Therefore, on the basis of microelectromechanical systems (MEMS) technology, many gyroscopes have been developed and successfully commercialized. A MEMS gyroscope consists of a MEMS device and an electrical circuit for self-oscillation and angular-rate detection. Since the MEMS device and circuit are interactively related, the entire system should be analyzed together to design or test the gyroscope. In this study, a MEMS vibratory gyroscope is analyzed based on the system dynamic modeling; thus, it can be mathematically expressed and integrated into a circuit simulator. A behavioral simulation of the entire system was conducted to prove the self-oscillation and angular-rate detection and to determine the circuit parameters to be optimized. From the simulation, the operating characteristic according to the vacuum pressure and scale factor was obtained, which indicated similar trends compared with those of the experimental results. The simulation method presented in this paper can be generalized to a wide range of MEMS devices.

  10. Two Novel Measurements for the Drive-Mode Resonant Frequency of a Micromachined Vibratory Gyroscope

    Directory of Open Access Journals (Sweden)

    Ancheng Wang

    2013-11-01

    Full Text Available To investigate the drive-mode resonance frequency of a micromachined vibratory gyroscope (MVG, one needs to measure it accurately and efficiently. The conventional approach to measure the resonant frequency is by performing a sweep frequency test and spectrum analysis. The method is time-consuming and inconvenient because of the requirements of many test points, a lot of data storage and off-line analyses. In this paper, we propose two novel measurement methods, the search method and track method, respectively. The former is based on the magnitude-frequency characteristics of the drive mode, utilizing a one-dimensional search technique. The latter is based on the phase-frequency characteristics, applying a feedback control loop. Their performances in precision, noise resistivity and efficiency are analyzed through detailed simulations. A test system is implemented based on a field programmable gate array (FPGA and experiments are carried out. By comparing with the common approach, feasibility and superiorities of the proposed methods are validated. In particular, significant efficiency improvements are achieved whereby the conventional frequency method consumes nearly 5,000 s to finish a measurement, while only 5 s is needed for the track method and 1 s for the search method.

    In this paper, we investigate the application of a vibratory shear-enhanced filtration system (VSEP) to separation of water from oil-in-water emulsions. The VSEP module consists in an annular membrane of 500 cm(2) area which oscillates azimuthally in its own plane with an amplitude depending upon frequency. Polyethersulfone (PES) membranes of 50 and 20 kDa were used. Test fluids consisted of oil-in-water emulsion at an oil concentration of 4% prepared from a concentrated cutting fluid. The critical flux for stable operation was investigated by increasing the permeate flux in steps while monitoring the transmembrane pressure (TMP). With a 50 kDa membrane the flux increased nonlinearly with TMP and reached 250 L h(-1)m(-2) at a TMP of 1500 kPa while permeate turbidity decayed from 1.8 to 0.9 NTU above 600 kPa from an initial emulsion turbidity of 21,900 NTU. With the 20 kDa membrane, the flux increased linearly with TMP until 1600 kPa, but the oil concentration in permeate became negligible (turbidity near zero NTU). Concentration tests showed that the flux decreased linearly with ln(VRR) where VRR is the volume reduction ratio while permeate turbidity increased exponentially to 25NTU above a VRR of 4. This work confirms the high performance of the VSEP for oil separation from water in metal working emulsions. Copyright (c) 2010 Elsevier B.V. All rights reserved.

    Because more than 70% of children with cancer become long-term survivors, more emphasis is put on reducing late effects. Cryopreservation of semen and the intracytoplasmic sperm injection technique makes it possible to obtain pregnancy with very poor sperm quality. Two new semen retrieval methods are described that are applicable in pubertal boys with a fertility potential, although not psychologically ready to produce a semen sample, who are likely to become infertile because of anticancer therapy. Two pubertal boys (aged 14 and 15 years) had a late testicular relapse of pre-B acute lymphoblastic leukemia and Hodgkin disease, stage II, respectively. In patient 1, penile vibratory stimulation (PVS) was tried under general anesthesia without success and electroejaculation (EEJ) was performed. Before alkylating chemotherapy and testicular irradiation, PVS was performed with success in patient 2. An antegrade ejaculate of 0.7 ml with 1% motile spermatozoa and an retrograde ejaculate with 1.6 x 10(6)/ml spermatozoa (5% with fair motility) was obtained from patient 1. An antegrade ejaculate of 1.5 ml with 2.5 x 10(6)/ml spermatozoa (29% with fair motility) was obtained from patient 2. PVS should be the first choice of treatment because it is noninvasive, simple, and easily applied. Because EEJ requires general anesthesia, it should be used as a second option.

    Alarm signalling is of paramount importance to communication in all social insects. In termites, vibroacoustic and chemical alarm signalling are bound to operate synergistically but have never been studied simultaneously in a single species. Here, we inspected the functional significance of both communication channels in Constrictotermes cyphergaster (Termitidae: Nasutitermitinae), confirming the hypothesis that these are not exclusive, but rather complementary processes. In natural situations, the alarm predominantly attracts soldiers, which actively search for the source of a disturbance. Laboratory testing revealed that the frontal gland of soldiers produces a rich mixture of terpenoid compounds including an alarm pheromone. Extensive testing led to identification of the alarm pheromone being composed of abundant monoterpene hydrocarbons (1S)-α-pinene and myrcene, along with a minor component, (E)-β-ocimene. The vibratory alarm signalling consists of vibratory movements evidenced as bursts; a series of beats produced predominantly by soldiers. Exposing termite groups to various mixtures containing the alarm pheromone (crushed soldier heads, frontal gland extracts, mixture of all monoterpenes, and the alarm pheromone mixture made of standards) resulted in significantly higher activity in the tested groups and also increased intensity of the vibratory alarm communication, with the responses clearly dose-dependent. Lower doses of the pheromone provoked higher numbers of vibratory signals compared to higher doses. Higher doses induced long-term running of all termites without stops necessary to perform vibratory behaviour. Surprisingly, even crushed worker heads led to low (but significant) increases in the alarm responses, suggesting that other unknown compound in the worker's head is perceived and answered by termites.

  6. Mondialization: The negation of territory

    2007-01-01

    Full Text Available The main objective of this paper is to present some weaknesses and inconsistence of the mondialization/globalization concept, especially regarding obvious negation of territoriality as a principle and a crude reality of uneven spatial distribution of resources, wealth and population on global scale. The domination of the globalism and neo-liberalism in the spheres of economy, society, culture and even language leads toward greater differences, in such intensity that some authors describe it as a "clash of civilizations". Loosing territoriality means loosing "raison d’etre" of spatial planning. Some efforts to introduce participation as a planning solution for the beginning of the new century is actually a Trojan horse and a step in the wrong direction.

  7. Prey availability affects territory size, but not territorial display behavior, in green anole lizards

    The availability of food resources can affect the size and shape of territories, as well as the behaviors used to defend territories, in a variety of animal taxa. However, individuals within a population may respond differently to variation in food availability if the benefits of territoriality vary among those individuals. For example, benefits to territoriality may differ for animals of differing sizes, because larger individuals may require greater territory size to acquire required resources, or territorial behavior may differ between the sexes if males and females defend different resources in their territories. In this study, we tested whether arthropod abundance and biomass were associated with natural variation in territory size and defense in insectivorous green anole lizards, Anolis carolinensis. Our results showed that both male and female lizards had smaller territories in a habitat with greater prey biomass than lizards in habitats with less available prey, but the rates of aggressive behaviors used to defend territories did not differ among these habitats. Further, we did not find a relationship between body size and territory size, and the sexes did not differ in their relationships between food availability and territory size or behavioral defense. Together, these results suggest that differences in food availability influenced male and female territorial strategies similarly, and that territory size may be more strongly associated with variation in food resources than social display behavior. Thus, anole investment in the behavioral defense of a territory may not vary with territory quality.

    2015-02-01

    To examine penile vibratory stimulation (PVS) in the treatment of post-prostatectomy urinary incontinence (UI). Patients with post-prostatectomy UI were included in a 12-week trial. A 24-hr pad test and a 72-hr voiding diary were collected at baseline. Participants were randomized to receive PVS for the first 6 weeks (group 1) or for the final 6 weeks (group 2) of the study. The primary outcome was the difference in leakage between groups 1 and 2 at 6 weeks as measured by changes in the pad test. The trial was registered at www.clinicaltrials.org (NCT01540656). Data from 31 men were available for analyses. The difference in the change on the pad test between the groups did not reach statistical significance at 6 weeks (P = 0.13) while the change in incontinence episodes between groups approached statistical significance (P = 0.052). However, there was a median reduction of -33 g (P = 0.021) on the pad test and a median reduction in daily incontinence episodes of -1 (P = 0.023) in group 1 at 6 weeks. At 12 weeks, group 2 had a median decrease on the pad test of -8 g (P = 0.10) and no change in incontinence episodes. A pooled analysis showed a decline on the pad test of -13.5 g (P = 0.004) after PVS. Small improvements were seen in subjective symptom scores and 58% stated to be satisfied with PVS. Self-limiting side effects were experienced by 15% of patients. PVS is feasible in the treatment of post-prostatectomy UI. Larger trials are needed to document the clinical efficacy. © 2013 Wiley Periodicals, Inc.

  10. Effect of Axial Force on the Performance of Micromachined Vibratory Rate Gyroscopes

    2010-12-01

    Full Text Available It is reported in the published literature that the resonant frequency of a silicon micromachined gyroscope decreases linearly with increasing temperature. However, when the axial force is considerable, the resonant frequency might increase as the temperature increases. The axial force is mainly induced by thermal stress due to the mismatch between the thermal expansion coefficients of the structure and substrate. In this paper, two types of micromachined suspended vibratory gyroscopes with slanted beams were proposed to evaluate the effect of the axial force. One type was suspended with a clamped-free (C-F beam and the other one was suspended with a clamped-clamped (C-C beam. Their drive modes are the bending of the slanted beam, and their sense modes are the torsion of the slanted beam. The relationships between the resonant frequencies of the two types were developed. The prototypes were packaged by vacuum under 0.1 mbar and an analytical solution for the axial force effect on the resonant frequency was obtained. The temperature dependent performances of the operated mode responses of the micromachined gyroscopes were measured. The experimental values of the temperature coefficients of resonant frequencies (TCF due to axial force were 101.5 ppm/°C for the drive mode and 21.6 ppm/°C for the sense mode. The axial force has a great influence on the modal frequency of the micromachined gyroscopes suspended with a C-C beam, especially for the flexure mode. The quality factors of the operated modes decreased with increasing temperature, and changed drastically when the micromachined gyroscopes worked at higher temperatures.

    To examine safety and efficacy of use of a clitoral vacuum suction device (CVSD) versus vibratory stimulation (V) to treat orgasmic dysfunction in women with MS or SCI. Randomized clinical trial. Two academic medical centers. Thirty-one women including 20 with MS and 11 with SCI. A 12-week trial of the use of a CVSD versus V MAIN OUTCOME MEASURES: Female Sexual Function Inventory (FSFI) and Female Sexual Distress Scale (FSDS). 23 women (18 MS; 5 SCI) completed the study including 13/16 randomized to CVSD and 10/15 randomized to V. There was a statistically significant increase in total FSFI score (p=.011), desire (p=. 009), arousal (p=.009), lubrication (p=.008), orgasm (p=.012), and satisfaction (p=.049) and a significant decrease in distress as measured by FSDS (p=.020) in subjects using the CVSD. In subjects who used V, there was a statistically significant increase in the orgasm subscale of the FSFI (p=.028). Subjects using the CVSD maintained improvements 4 weeks after treatment. CVSD is safe and overall efficacious to treat female neurogenic sexual dysfunction related to MS and SCI. V is also safe and efficacious to female neurogenic orgasmic dysfunction; however, results were limited to the active treatment period. Due to ease of access and cost, clinicians can consider use of V for women with MS or SCI with orgasmic dysfunction. CVSD is recommended for women with multiple sexual dysfunctions or for whom V is ineffective. Copyright © 2017 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

    2017-05-01

    Full Text Available Introduction Iran is a frontier of pomegranate fruit production in the world (with almost 40 % of the world`s production. However due to traditional processing operations is not ranked as the largest pomegranate exporter. Saveh, Neyriz and Ferdows are the top pomegranate producing cities in Iran. Pomegranate is consumed as a fresh fruit as well as processed product as food additive, paste, syrup, jelly, pectin, jam, beverage, essence, vinegar and concentrate. Aril extraction is the first and essential postharvest operation for pomegranate processing. Arils are mostly extracted manually even in large scales for fresh and processed consumption. This labor intensive operation is rational when aril quality is an important index for consumer. But whenever pomegranate juice is desired, the aril quality has no priority for consumer, and therefore arils can be extracted with less care. Sarig (1985 was the first inventor of a pomegranate aril extractor who employed air jet force to extract the arils. Later, other researchers employed the same method as well as water jet to extract fruit juice and sac. In the present study, fabrication and evaluation of vibratory aril extractor augmented with air system was conducted. Materials and Methods The study was conducted using Rabab cultivar samples which were manually harvested from an orchard in Neyriz town, Fars province. Samples were kept in refrigerator at 5 0C till experimental trials. Initial moisture content of fruit skin, arils and internal fleshes were measured by gravimetric method as 31.7±2.6 %, 61.5±1.8 % and 42.8±1.4 %, respectively and for a whole fruit was measured 45.3±11.5 % (w.b.. For conducting laboratory tests, an aril extraction unit was designed and fabricated. It comprised a steel main frame, a 746 W electric motor, drive mechanism (eccentric and shaft, sample retentive unit, air jet unit, aril tank, and an air compressor-tank assembly.

    To quantitatively analyze the vibratory characteristics of vocal folds before and after conservative treatments to evaluate the outcomes of conservative treatments for vocal fold leukoplakia using videostrobokymography (VSK). This is a prospective study. Twenty patients and 20 controls were enrolled into the study. All patients received conservative treatments for 3 weeks and received VSK examination before and 3 weeks after the treatments. All controls only received VSK examination once. Vocal fold lengths of 25%, 50%, and 75% were chosen as the line-scan positions to evaluate the vocal fold vibration. Open quotient (OQ) and asymmetry index (AI) were obtained using VSK. Significant improvements in the main symptoms including voice hoarseness were found. Videostroboscopic findings showed that the white lesions on the vocal folds almost completely disappeared in all patients, and the vocal fold flexibility returned to normal. All OQs and AIs at each line-scan position in patients before the treatments were larger than those in controls (P  0.017). VSK could quantitatively evaluate the vibratory characteristics of vocal folds before and after the treatments, and conservative treatment could improve VSK measurements to normal control values, suggesting that VSK is a tool to assess the outcomes of the conservative treatments for vocal fold leukoplakia.

    Full Text Available The aim of this research is to analyze territorial capital as a new paradigm to make best use of endogenous assets. The study is dealing with the preconditions, meaning and possible theoretical taxonomies of territorial capital. In this study I emphasize that the cumulative effects of regional potentials are more important than economies of scale and location factors. I present different approaches and interpretations of territorial capital, then make an attempt to create an own model. I try to find answers for questions, such as why territorial capital shows a new perspective of urban and regional development; how cognitive elements of territorial capital provide increasing return; how territorial capital influences competitiveness and what kind of relation it has with cohesion.

    Full Text Available Territorial cohesion is a complex concept that cannot be explained by a single definition. During the previous decades, territorial issues represented, undoubtedly, subjects of interest for various policy documents, actions and funding of the European Union, but the asymmetric impact of recent global crisis, doubled by the launch of the Green Paper (2008 and its inclusion in the Lisbon Treaty, in 2009, has underlined the importance of territorial cohesion, as one of the three main pillars of the new cohesion policy. In this context, this article tries to create a holistic perspective on territorial cohesion by analyzing the available studies and to determine its relevance to the European objective of strengthening the regions, promoting territorial integration and producing coherent policies, thus contributing to the sustainable development and global competitiveness of the European Union.

We identify special disposals related to national minorities in Romanian Constitution, in the law of local public administration, the law of education, the law concerning the election of the Chamber of Deputies and Senate, the law related to political parties, the law for the election of the authorities of local public administration, the law concerning the combating of all forms of discrimination. In the last project of the Law concerning the statute of national minorities in Romania, a new concept is introduced: cultural autonomy of minorities. The cultural autonomy is a form of non-territorial autonomy. Nevertheless, Romania is criticised by some international organisations for the fact that the organisations of national minorities represented in the Parliament of Romania have instituted a monopole, therefore no other organisation of any minority is allowed to participate to the elections.

  15. Extra-territorial movements differ between territory holders and subordinates in a large, monogamous rodent.

    Territorial animals carry out extra-territorial movements (forays) to obtain pre-dispersal information or to increase reproductive success via extra-pair copulation. However, little is known about other purposes and spatial movement patterns of forays. In this study, we GPS-tagged 54 Eurasian beavers (Castor fiber), a year-round territorial, monogamous mammal, during the non-mating season. We investigated forays in territory-holding breeders (dominants) and non-breeding (subordinate) family members. Twenty of 46 dominant individuals (44%), and 6 of 10 subordinates (60%) conducted forays. Generally, beavers spent between 0 and 11% of their active time on forays, travelled faster and spend more time in water when on forays compared to intra-territorial movements, suggesting that forays are energetically costly. Further, beavers in smaller territories conducted more forays. Possibly, smaller territories might not have sufficient resources and thus dominant individuals might conduct forays to assess possibilities for territory expansion, and potentially for foraging. Generally, besides territory advertisement (e.g. via scent-marking), forays might serve as an additional mechanism for territory owners to assess neighbours. Subordinates spent more time on forays, moved greater distances and intruded into more territories than dominant individuals did, suggesting that they prospected to gain information on the population density and available mates before dispersal.

    This article deals with the time dependent analysis of thermally conducting and Magneto-hydrodynamic (MHD) liquid film flow of a fourth order fluid past a vertical and vibratory plate. In this article have been developed for higher order complex nature fluids. The governing-equations have been modeled in the terms of nonlinear partial differential equations with the help of physical boundary circumstances. Two different analytical approaches i.e. Adomian decomposition method (ADM) and the optimal homotopy asymptotic method (OHAM), have been used for discoveryof the series clarification of the problems. Solutions obtained via two diversemethods have been compared using the graphs, tables and found an excellent contract. Variants of the embedded flow parameters in the solution have been analysed through the graphical diagrams.

  17. Low-frequency vibratory exercise reduces the risk of bone fracture more than walking: a randomized controlled trial.

    Gusi, Narcís; Raimundo, Armando; Leal, Alejo

    2006-11-30

    Whole-body vibration (WBV) is a new type of exercise that has been increasingly tested for the ability to prevent bone fractures and osteoporosis in frail people. There are two currently marketed vibrating plates: a) the whole plate oscillates up and down; b) reciprocating vertical displacements on the left and right side of a fulcrum, increasing the lateral accelerations. A few studies have shown recently the effectiveness of the up-and-down plate for increasing Bone Mineral Density (BMD) and balance; but the effectiveness of the reciprocating plate technique remains mainly unknown. The aim was to compare the effects of WBV using a reciprocating platform at frequencies lower than 20 Hz and a walking-based exercise programme on BMD and balance in post-menopausal women. Twenty-eight physically untrained post-menopausal women were assigned at random to a WBV group or a Walking group. Both experimental programmes consisted of 3 sessions per week for 8 months. Each vibratory session included 6 bouts of 1 min (12.6 Hz in frequency and 3 cm in amplitude with 60 degrees of knee flexion) with 1 min rest between bouts. Each walking session was 55 minutes of walking and 5 minutes of stretching. Hip and lumbar BMD (g.cm-2) were measured using dual-energy X-ray absorptiometry and balance was assessed by the blind flamingo test. ANOVA for repeated measurements was adjusted by baseline data, weight and age. After 8 months, BMD at the femoral neck in the WBV group was increased by 4.3% (P = 0.011) compared to the Walking group. In contrast, the BMD at the lumbar spine was unaltered in both groups. Balance was improved in the WBV group (29%) but not in the Walking group. The 8-month course of vibratory exercise using a reciprocating plate is feasible and is more effective than walking to improve two major determinants of bone fractures: hip BMD and balance.

    From psychological and sociological standpoints, aggression is regarded as intentional behavior aimed at inflicting pain and manifested by hostility and attacking behaviors. In contrast, biologists define aggression as behavior associated with attack or escalation toward attack, omitting any stipulation about intentions and goals. Certain animal signals are strongly associated with escalation toward attack and have the same function as physical attack in intimidating opponents and winning contests, and ethologists therefore consider them an integral part of aggressive behavior. Aggressive signals have been molded by evolution to make them ever more effective in mediating interactions between the contestants. Early theoretical analyses of aggressive signaling suggested that signals could never be honest about fighting ability or aggressive intentions because weak individuals would exaggerate such signals whenever they were effective in influencing the behavior of opponents. More recent game theory models, however, demonstrate that given the right costs and constraints, aggressive signals are both reliable about strength and intentions and effective in influencing contest outcomes. Here, we review the role of signaling in lieu of physical violence, considering threat displays from an ethological perspective as an adaptive outcome of evolutionary selection pressures. Fighting prowess is conveyed by performance signals whose production is constrained by physical ability and thus limited to just some individuals, whereas aggressive intent is encoded in strategic signals that all signalers are able to produce. We illustrate recent advances in the study of aggressive signaling with case studies of charismatic taxa that employ a range of sensory modalities, viz. visual and chemical signaling in cephalopod behavior, and indicators of aggressive intent in the territorial calls of songbirds.

    Full Text Available Globalization has led to an increased international trade relations between organizations spatially separated. This determined a greater spatial differentiation influenced by local and regional competition production systems. Territoriality has been considered as the main cause for the development of active areas, explaining also the success of certain local systems of production that became competitive on a global scale. The new school of regional competitiveness promoted by Porter (2003 identifies the cluster industry as a source of competitive advantages, supporting the identification and cluster setting – up as an objective of the public policy. In the last few years, clusters became an important basis for the new policies promoted at the level of the European Union. The challenges established through the Lisbon Strategy, respectively “to make the Europe the most competitive and dynamic based knowledge economy”, determinate a new approach of the economic policy in order to increase competitiveness. For the regional economy, the cluster has the aim to develop new strategies focused on the economic sectors of the regional development, by taking into account sectoral advantages. However, in terms of economic activities promoted at regional level, the spatial development is an essential component for increasing EU competitiveness in terms of economic globalization trends, regional networks being considered the most advanced form of cluster in the economic sector.

    A relationship between altered postural control and injury has been reported in sports. Sensorimotor function serves a fundamental role in postural control and is not often studied in runners. Persons who sustain running injury may have altered sensorimotor function contributing to risk of injury or reinjury. To determine if differences in knee and ankle proprioception or plantar sensation exist between injured and noninjured runners. Retrospective case-control study. University campus. Twenty runners with a history of lower-extremity overuse injury and 20 noninjured runners were examined. Injured runners were subcategorized into 2 groups based on site of injury: foot/ankle and knee/hip. Active absolute joint-repositioning error of the ankle at 20° inversion and 10° eversion and the knee at 15° and 40° flexion was assessed using an isokinetic dynamometer. Vibratory threshold at the calcaneus, arch, and great toe was determined for each subject using a handheld electric sensory threshold instrument. Runners in the injured-foot/ankle group had increased absolute error during ankle-eversion repositioning (6.55° ± 3.58°) compared with those in the noninjured (4.04° ± 1.78°, P = .01) and the hip/knee (3.63° ± 2.2°, P = .01) groups. Runners in the injured group, as a whole, had greater sensitivity in the arch of the plantar surface (2.94 ± 0.52 V) than noninjured runners (2.38 ± 0.53 V, P = .02). Differences in ankle-eversion proprioception between runners with a history of ankle and foot injuries and noninjured runners were observed. Runners with a history of injury also displayed an increased vibratory threshold in the arch region compared with noninjured runners. Poor ankle-joint-position sense and increased plantar sensitivity suggest altered sensorimotor function after injury. These factors may influence underlying postural control and contribute to altered loading responses commonly observed in injured runners.

    2006-11-01

    Full Text Available Abstract Background Whole-body vibration (WBV is a new type of exercise that has been increasingly tested for the ability to prevent bone fractures and osteoporosis in frail people. There are two currently marketed vibrating plates: a the whole plate oscillates up and down; b reciprocating vertical displacements on the left and right side of a fulcrum, increasing the lateral accelerations. A few studies have shown recently the effectiveness of the up-and-down plate for increasing Bone Mineral Density (BMD and balance; but the effectiveness of the reciprocating plate technique remains mainly unknown. The aim was to compare the effects of WBV using a reciprocating platform at frequencies lower than 20 Hz and a walking-based exercise programme on BMD and balance in post-menopausal women. Methods Twenty-eight physically untrained post-menopausal women were assigned at random to a WBV group or a Walking group. Both experimental programmes consisted of 3 sessions per week for 8 months. Each vibratory session included 6 bouts of 1 min (12.6 Hz in frequency and 3 cm in amplitude with 60° of knee flexion with 1 min rest between bouts. Each walking session was 55 minutes of walking and 5 minutes of stretching. Hip and lumbar BMD (g·cm-2 were measured using dual-energy X-ray absorptiometry and balance was assessed by the blind flamingo test. ANOVA for repeated measurements was adjusted by baseline data, weight and age. Results After 8 months, BMD at the femoral neck in the WBV group was increased by 4.3% (P = 0.011 compared to the Walking group. In contrast, the BMD at the lumbar spine was unaltered in both groups. Balance was improved in the WBV group (29% but not in the Walking group. Conclusion The 8-month course of vibratory exercise using a reciprocating plate is feasible and is more effective than walking to improve two major determinants of bone fractures: hip BMD and balance.

    Neurophysiological deficits could make patients with Ehlers-Danlos syndrome (EDS) type III (hypermobility type) more vulnerable to musculoskeletal problems, particularly to joint instability. The purpose of this study was to investigate whether joint position sense (JPS) and vibratory perception sense (VPS) in EDS type III patients in the knee and shoulder joints are impaired. Thirty-two female EDS type III patients as defined by the Villefranche criteria and 32 individually gender- and age-matched healthy control subjects were included in the study. Range of motion was determined using a goniometer, passive and active JPS were assessed with an isokinetic dynamometer system, and the VPS was measured by a biothesiometer. Daily physical activity was evaluated by the Baecke questionnaire. The EDS type III group showed significantly larger ranges of movement (P physical activity (SPA) compared to the control group (P = 0.023). Considering SPA as covariate, the EDS type III group demonstrated a significant impairment in knee joint reposition compared to the control group (P = 0.018). No significant differences were found for shoulder JPS. The VPS was not significantly different in the EDS type III group compared to the control group. In addition, no significant correlation was found between JPS and VPS, neither at the knee nor at the shoulder joint. This is the first study examining proprioception deficits in EDS type III patients as defined by the Villefranche criteria. Further research on the neurophysiological dysfunctions and mechanisms in this pathologic entity is needed.

  16. Design and Analysis of a Novel Fully Decoupled Tri-axis Linear Vibratory Gyroscope with Matched Modes.

    Xia, Dunzhu; Kong, Lun; Gao, Haiyu

    2015-07-13

    We present in this paper a novel fully decoupled silicon micromachined tri-axis linear vibratory gyroscope. The proposed gyroscope structure is highly symmetrical and can be limited to an area of about 8.5 mm × 8.5 mm. It can differentially detect three axes' angular velocities at the same time. By elaborately arranging different beams, anchors and sensing frames, the drive and sense modes are fully decoupled from each other. Moreover, the quadrature error correction and frequency tuning functions are taken into consideration in the structure design for all the sense modes. Since there exists an unwanted in-plane rotational mode, theoretical analysis is implemented to eliminate it. To accelerate the mode matching process, the particle swam optimization (PSO) algorithm is adopted and a frequency split of 149 Hz is first achieved by this method. Then, after two steps of manual adjustment of the springs' dimensions, the frequency gap is further decreased to 3 Hz. With the help of the finite element method (FEM) software ANSYS, the natural frequencies of drive, yaw, and pitch/roll modes are found to be 14,017 Hz, 14,018 Hz and 14,020 Hz, respectively. The cross-axis effect and scale factor of each mode are also simulated. All the simulation results are in good accordance with the theoretical analysis, which means the design is effective and worthy of further investigation on the integration of tri-axis accelerometers on the same single chip to form an inertial measurement unit.

  17. Experimental Investigation on the Fatigue Life of Ti-6Al-4V Treated by Vibratory Stress Relief

    Directory of Open Access Journals (Sweden)

    Han-Jun Gao

    2017-05-01

    Full Text Available Vibratory stress relief (VSR is a highly efficient and low-energy consumption method to relieve and homogenize residual stresses in materials. Thus, the effect of VSR on the fatigue life should be determined. Standard fatigue specimens are fabricated to investigate the fatigue life of Ti-6Al-4V titanium alloy treated by VSR. The dynamic stresses generated under different VSR amplitudes are measured, and then the relationship between the dynamic stress and vibration amplitude is obtained. Different specimen groups are subjected to VSRs with different amplitudes and annealing treatment with typical process parameters. Residual stresses are measured to evaluate the stress relieving effects. Finally, the fatigue behavior under different states is determined by uniaxial tension–compression fatigue experiments. Results show that VSR and annealing treatment have negative effects on the fatigue life of Ti-6Al-4V. The fatigue life is decreased with the increase in VSR amplitude. When the VSR amplitude is less than 0.1 mm, the decrease in fatigue limit is less than 2%. Compared with specimens without VSR or annealing treatment, the fatigue limit of the specimens treated by VSR with 0.2 mm amplitude and annealing treatment decreases by 10.60% and 8.52%, respectively. Although the stress relieving effect is better, high amplitude VSR will lead to the decrease of Ti-6Al-4V fatigue life due to the defects generated during vibration. Low amplitude VSR can effectively relieve the stress with little decrease in fatigue life.

    [corrected] We investigated which nerve pathways are necessary to achieve ejaculation using penile vibratory stimulation (PVS) in men with spinal cord injury (SCI). Eight men with SCI were selected based on the presence of a bulbocavernosus reflex (BCR) and consistent antegrade ejaculation with PVS. Level of injury was cervical (4), upper thoracic (4), and lower thoracic (1). Mean age was 30.4 years (range 22 to 38). Usual responses to PVS included autonomic dysreflexia (4), erection (4), and consistent somatic responses such as abdominal contractions (8). Local anesthesia of the dorsal penile nerves (penile block) was achieved using 1% plain lidocaine injection. Effective penile block was confirmed by loss of the BCR. Two PVS ejaculation trials were performed: one trial during the penile block and one trial when the penile block had worn off. In 4 subjects, the bladder contents were analyzed for retrograde ejaculation. With the penile block, ejaculation was inhibited in 100% of the subjects. None of the bladder washings demonstrated sperm, indicating absence of retrograde ejaculation. None of the subjects exhibited their usual erectile response, somatic responses, or signs of autonomic dysreflexia. After the penile block wore off, PVS induced ejaculation in all subjects. If subjects usually had erection, somatic responses, or signs of autonomic dysreflexia, these also returned. Our data suggest that ejaculatory response to PVS in SCI men requires the presence of intact dorsal penile nerves.

  19. Testosterone affects song modulation during simulated territorial intrusions in male black redstarts (Phoenicurus ochruros.

    Directory of Open Access Journals (Sweden)

    Beate Apfelbeck

    Full Text Available Although it has been suggested that testosterone plays an important role in resource allocation for competitive behavior, details of the interplay between testosterone, territorial aggression and signal plasticity are largely unknown. Therefore, we investigated if testosterone acts specifically on signals that communicate the motivation or ability of individuals to engage in competitive situations in a natural context. We studied the black redstart, a territorial songbird species, during two different life-cycle stages, the early breeding phase in spring and the non-breeding phase in fall. Male territory holders were implanted with the androgen receptor blocker flutamide (Flut and the aromatase inhibitor letrozole (Let to inhibit the action of testosterone and its estrogenic metabolites. Controls received a placebo treatment. Three days after implantation birds were challenged with a simulated territorial intrusion (STI. Song was recorded before, during and after the challenge. In spring, both treatment groups increased the number of elements sung in parts of their song in response to the STI. However, Flut/Let-implanted males reacted to the STI with a decreased maximum acoustic frequency of one song part, while placebo-implanted males did not. Instead, placebo-implanted males sang the atonal part of their song with a broader frequency range. Furthermore, placebo-, but not Flut/Let-implanted males, sang shorter songs with shorter pauses between parts in the STIs. During simulated intrusions in fall, when testosterone levels are naturally low in this species, males of both treatment groups sang similar to Flut/Let-implanted males during breeding. The results suggest that song sung during a territorial encounter is of higher competitive value than song sung in an undisturbed situation and may, therefore, convey information about the motivation or quality of the territory holder. We conclude that testosterone facilitates context-dependent changes

    Full Text Available In the Ecuadorian province of Azuay, agro-ecology seems to signal towards the rebirth of family agriculture in a context of regional migration. Given changes in land usage and the improvement of peasant economies, we envisage a profound mutation in the rural landscape of Azuay. Notwithstanding, in lieu of a true model of territorial rural development, the term territorial resistance is used as weak regional commercial networks do not allow an adequate integration of a majority of peasants, evidencing the need for a more ambitious vision that takes into account the close ties between rural and urban areas, to assist the insertion of poor peasant farmers into commercial agriculture.

  5. In Space and Time: Territorial Animals are Attracted to Conspecific Chemical Cues

    Campos, Stephanie M.; Strauss, Chloe; Martins, Emília P.

    2017-01-01

    Territorial animals lay scent marks around their territories to broadcast their presence, but these olfactory signals can both attract and repel con-specifics. Attraction or aversion can have a profound impact in terms of space use and thereby influence an individual’s access to resources and mates. Here, we test the impact of chemical signals on the long-term space use and activity of receivers, comparing the response of males and females, territory holders, and temporary visitors in Sceloporus undulatus lizards in the field. We placed either male femoral gland secretions (chemical) or blank (control) cues on resident male landmarks, repeatedly over 5 d, while monitoring the activity and location of all lizards in the vicinity. We found that resident males and females, but not non-resident males, were active on more days near landmarks treated with chemical cues than landmarks treated with control cues. Non-resident males remained closer to chemical than control cues. These results suggest that territorial scent marks are attractive to conspecifics and impact space use, but that the specific effects depend on receiver sex and residency status. Such subtle or gradual changes in behavior may frequently be overlooked by short-term choice experiments. Future studies investigating the behavioral significance of a communicative signal should consider these finer details of behavior for a more comprehensive assessment. PMID:28413237

    Research highlights: Low-dimensional human glottal area data. Evidence of chaos in human laryngeal activity from high-speed digital imaging. Traditional perturbation analysis should be cautiously applied to aperiodic high speed image signals. Nonlinear dynamic analysis may be helpful for understanding disordered behaviors in pathological laryngeal systems. - Abstract: Laryngeal pathology is usually associated with irregular dynamics of laryngeal activity. High-speed imaging facilitates direct observation and measurement of vocal fold vibrations. However, chaotic dynamic characteristics of aperiodic high-speed image data have not yet been investigated in previous studies. In this paper, we will apply nonlinear dynamic analysis and traditional perturbation methods to quantify high-speed image data from normal subjects and patients with various laryngeal pathologies including vocal fold nodules, polyps, bleeding, and polypoid degeneration. The results reveal the low-dimensional dynamic characteristics of human glottal area data. In comparison to periodic glottal area series from a normal subject, aperiodic glottal area series from pathological subjects show complex reconstructed phase space, fractal dimension, and positive Lyapunov exponents. The estimated positive Lyapunov exponents provide the direct evidence of chaos in pathological human vocal folds from high-speed digital imaging. Furthermore, significant differences between the normal and pathological groups are investigated for nonlinear dynamic and perturbation analyses. Jitter in the pathological group is significantly higher than in the normal group, but shimmer does not show such a difference. This finding suggests that the traditional perturbation analysis should be cautiously applied to high speed image signals. However, the correlation dimension and the maximal Lyapunov exponent reveal a statistically significant difference between normal and pathological groups. Nonlinear dynamic analysis is capable of

  10. Resolution of territorial disputes in international law

    Directory of Open Access Journals (Sweden)

    Tubić Bojan N.

    2015-01-01

    Full Text Available Territorial disputes in international law are resolved by peaceful means, like negotiations, mediation, conciliation, arbitration and in the procedure at the International Court of Justice. Borders between states are, in practice, determined on the basis of the uti possidetis iuris principle and principle of effective control. Historical arguments for territorial acquisition are not generally accepted, because changes of borders have to be a result of democratically expressed will of states. Also, the right of people for self-determination was used in the process of decolonization for creating new states but it has emerged in later years like in the case of East Timor, as a legal title for gaining independence. Apart from the process of decolonization, the right to self-determination is rather unclear and disputable regarding its scope and content. Traditional modes of territorial acquisition still have decisive role in international law. Almost all states rely on them in order to substantiate their claims for possession of certain territories. Therefore, international courts and arbitrations cannot ignore them.

    Full Text Available The aim of this paper is to reveal the nuclei, flows and surfaces generated by tourism in Guatemala that, nowadays, constitute the basis for the promotion of the country in the international market. Following the trend in Central America, and after a long civil war, Guatemala is encouraging the growth of its tourism economy. The starting point of this research is rooted in the fact that there are only a handful of places, distributed over the Guatemalan territory, that articulate the tourist flows (constituted mainly by international visitors and onto which tourism surfaces are being constructed. We assume that this territorial structure is still weak, does not include all areas of the country and it is mostly dependant on regional emitting markets. The context of the territorial structure of tourism in Guatemala suggests that all countries in the region are competing to get access to the international tourism market and that this competition will be decided in favour of those nations that mastermind the administration of their natural and cultural resources. At the end of the text, we comment on the basics of the territorial structure found by our study.

  2. Territory choice during the breeding tenure of male sedge warblers.

    Zając, Tadeusz; Bielański, Wojciech; Solarz, Wojciech

    2011-12-01

    A territorial male can shift the location of its territory from year to year in order to increase its quality. The male can base its decision on environmental cues or else on its breeding experiences (when territory shift is caused by breeding failure in previous seasons). We tested these possible mechanisms of territory choice in the sedge warbler (Acrocephalus schoenobaenus), a territorial migrating passerine that occupies wetlands. This species bases its territory choices on an environmental cue: tall wetland vegetation cover. We found that the magnitude of territory quality improvement between seasons (measured as the area of tall wetland vegetation) increased throughout the early stages of a male's breeding career as a result of territory shifts dependent on the earliness of arrival. The distance the territory was shifted between seasons depended negatively on the previous year's territory quality and, less clearly, on the previous year's mating success. On the other hand, previous mating or nesting success had no influence on territory quality improvement between seasons as measured in terms of vegetation. The results imply that tall wetland vegetation is a long-term, effective environmental cue and that a preference for territories in which this type of landcover prevails has evolved into a rigid behavioral mechanism, supplemented by short-term individual experiences of breeding failure.

    Full Text Available In the context of global criticism on urban sprawl, the questions which arises are: what can we do with the expansion forms already occurred in most part of our cities; can they be fully or partially integrated into the city? But first, which exactly are the common morphological features of urban expansion areas in large European cities, and (by comparison in Romania? The urban form correlated to these „sparwl patterns” and „sprawl mechanisms” shows more then the lack of planning, but a social input in occuping the territory, related with a specific meaning of the landscape. The paper explores the relationship between the five distinct morphological patterns ways of forming in relation to spatial and landscape shapes which they generate, in the territories of sprawl, all illustrated through case studies of Bucharest.

We try to move from a vision according to which education is identified with “infrastructures and services” needed to sustain the smart city “organism” (due also to the social capital that it may produce toward a “new” vision that recovers the founding role of the educative processes, through which the relationships between persons and inhabited territories are continuously reshaped. According to that we present: a a strategic and methodological approach focused on museal field and narrative as key elements of future "learning from smart cities"; b a model of an advanced integrated technological environment (mobile, web, internet of things designed to support such an approach. The need for a different approach to the monitoring of complex learning experiences is also underlined.

    Krbálek, Milan; Hrabák, Pavel; Bukáček, Marek

    2018-01-01

    The aim of the article is to give a more detailed insight into territorial social forces acting between pedestrians by means of headway distribution and spectral rigidity. Probabilistic distribution of time headways between consecutive pedestrians is studied theoretically and experimentally. Several original experiments/empirical observations are presented and compared to data obtained from previously published experiments. The study is restricted to an unidirectional one-lane motion where overtaking is forbidden. The main stress is put on natural choices of mutual interaction represented by logarithmic and hyperbolic potentials leading to gamma and generalized inverse Gaussian distribution respectively. We show that the time headway distribution does not sufficiently reflect the differences between such distributions. The tools related to spectral rigidity and compressibility are chosen instead so as to predict the territorial social forces more accurately. Surprisingly, pedestrian flow seems to show a higher level of synchronization (lower compressibility) than vehicular flow.

  11. Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal.

    Mayer, Martin; Zedrosser, Andreas; Rosell, Frank

    2017-06-01

    In territorial, socially monogamous species, the establishment and defense of a territory are an important strategy to maximize individual fitness, but the factors responsible for the duration of territory occupancy are rarely studied, especially in long-lived mammals. A long-term monitoring program in southeast Norway spanning over 18 years allowed us to follow the individual life histories of Eurasian beavers ( Castor fiber ) from adolescence in their natal family group to dispersal and territory establishment until the end of territory occupancy. We investigated whether territory size, resource availability, population density, and dispersal age could explain the duration of territory occupancy, which ranged from 1 to 11 years. The duration of territory occupancy was positively related to dispersal age, suggesting that individuals that delayed dispersal had a competitive advantage due to a larger body mass. This is in support with the maturation hypothesis, which states that an animal should await its physical and behavioral maturation before the acquisition of a territory. Further, we found that individuals that established in medium-sized territories occupied them longer as compared to individuals in small or large territories. This suggests that large territories are more costly to defend due to an increased patrolling effort, and small territories might not have sufficient resources. The lifetime reproductive success ranged from zero to six kits and generally increased with an increasing duration of territory occupancy. Our findings show the importance of holding a territory and demonstrate that dispersal decisions and territory selection have important consequences for the fitness of an individual.

    Little is known about the anatomy of the lymphatic system in the rabbit with regard to relationships between the lymphatic vessel and lymph node. According to our previous studies in human cadavers and canines, the superficial lymphatic system could be divided into lymphatic territories. The aim of this study was to completely map the superficial lymphatic system in the rabbit. We used our microinjection technique and histological analysis for dissecting studies and recently developed indocyanine green (ICG) fluorescent lymphography for demonstrating dynamic lymph flow in living rabbits. Real-time ICG fluorescent lymphography was performed in two living New Zealand White rabbits, and direct dye microinjection of the lymphatic vessels was performed in eight dead rabbits. To assess the relationships between the vascular and lymphatic systems in rabbits, we performed radiocontrast injection into arteries in two dead rabbits prior to the lymphatic injection. The ICG fluorescent lymphography revealed eight lymphatic territories in the preauricular, submandibular, root of the lateral neck, axillary, lumbar, inguinal, root of the tail, and popliteal regions. We injected blue acrylic dye into every lymphatic vessel 0.1 mm in diameter or larger. We then dissected and chased the stained lymphatic vessels proximally until the vessels connected to the first tier lymph node. This procedure was repeated throughout the body until all the relationships between the lymphatic vessels and lymph nodes were defined. The lymphatic system of the rabbit could be defined as eight lymphatic territories, each with its own lymphatic vessels and lymph node. Copyright © 2013 Wiley Periodicals, Inc.

  15. Territory holders and non-territory holders in Ayu fish coexist only in the population growth process due to hysteresis.

    Ayu fish form feeding territories during a non-breeding (growing) season. When the density of the fish increases, phases gradually change. In the early growing season, all fish can hold territories at low density. Once all territory sites are occupied, newcomers become floaters. As the density further increases, territory holders have to spend much more time in defending their own territory and lose the time to feed on algae. Eventually, all fish give up their own territories and then form a school. In contrast, when the density decreases, territories are directly reformed from the school. In short, ayu fish exhibit a different transition, called hysteresis, where the two transitions occur widely-apart from each other. The dynamics of this intrinsic phenomena has not been demonstrated in previous studies. We develop a rate equation to describe the population dynamics within territorial competition. Our model successfully reproduces territorial hysteresis and indicates that territory holders and floaters can coexist only in the process of population growth. Moreover, we also find that the two critical densities of territorial hysteresis are conspicuously different from each other when the increase of the density of floaters sharply influences (step-function-like) the territories.

    A dual-purpose nonresonant 2-degrees of freedom (DOF) drive-mode and 1-DOF sense-mode vibratory gyro/accelerometer fabricated using the economical ultraviolet-lithographie-galvanoformung-abformung (UV-LIGA) fabrication process using SU-8 photoresist is reported. The dual-purpose device presented is capable of detecting acceleration at the lower-frequency band and angular rate at the operating frequency band thereby functioning as both accelerometer and gyroscope. This is achieved by designing the structure such that the frequency response of the drive oscillator has two drive resonances with a flat zone between them, while the sense oscillator has one resonance, which is deliberately placed in the flat region between the two drive resonances. For angular rate detection, the device is operated in the flat zone at the sense resonance frequency at which the device is less susceptible to frequency variations due to both environmental variation and fabrication imperfections and hence is said to be operating in robust mode. The steady-state response and discrimination for angular rate and acceleration sensing have been devised using analytical modeling. The fabrication process is optimized to realize a gyro/accelerometer that has a 9-μm-thick nickel structural layer and 4-μm capacitive gaps. The overall miniature device size is 2.0 mm×1.9 mm. The experimental frequency response of the fabricated devices shows drive-mode resonances at 2.85 and 4.96 kHz and sense resonance at 3.85 kHz compared to the respective design values of drive-mode resonance frequencies 2.97 and 4.81 kHz and sense resonance frequency of 4 kHz. To demonstrate the dual-purpose capability of the device, acceleration characterization has been carried out and presented. The fabricated sensor is packaged in a ceramic package and interfaced with a MS3110 differential capacitive read out IC to characterize the acceleration response of the sensor, using an out-of-plane shaker.

    2017-01-01

    Full Text Available This study presents a numerical investigation using the finite element method on the vibratory behavior of a single spool gas turbine designed for unmanned aerial vehicle applications. The shaft of the rotor-bearing system is supported on a front bearing composed of a deep groove ball bearing with a vibration absorber element and a rear squeeze film damper bearing. Three radial clearances for the squeeze film damper were analyzed to determine the best geometric configuration for the rear bearing, considering the rotordynamic performance of the entire system. Whirl speeds and unbalanced system responses were carefully evaluated to determine the best radial clearance for the squeeze film damper. After defining the best radial clearance, a transient analysis was performed to simulate the transition of the system through resonance, and a spectral map is presented to illustrate the vibratory behavior of the system considering the influence of all related important frequencies. The rotordynamic behavior of the system is predicted, and vibration problems are avoided. Its mechanical drawings were released to manufacturing, and the first prototype is in the experimental test phase, thus indicating that the numerical results presented in this study are consistent.

    Females who choose highly ornamented mates may gain resources that improve offspring production and survival. Studies have focused on the relationship between male quality and the complexity of sexual ornaments; however, less is known of the communicative content of courtship displays, and whether they indicate the quality of resources males can provide to mates. Here, we used blue-black grassquits (Volatinia jacarina) to test the relationship between male display attributes and territory quality, measured as food availability. Our main hypothesis was that territory quality would be better predicted by dynamic displays than by static ornaments. During four breeding seasons in central Brazil, we quantified display song attributes (output and consistency) and the timing of nuptial molt. We measured territorial seed density, body condition, and ectoparasite infestation. We found a positive relationship between song output and territory seed density, suggesting this attribute provides a reliable indicator of territory quality. However, the timing of molt was unrelated to territory quality. Additionally, no other male attribute was associated with seed density. The link between song output and territory quality might reflect variation in male condition in response to territorial resources, or extra time males on higher quality territories have to invest in territorial defense.

    2014-06-01

    Full Text Available The article promotes an approach to assess the prospects of regional development on the basis of the synthesis of comparative and historical methods of research. According to the authors, the comparative analysis of the similar functioning of the socio-economic systems forms deeper understanding what part factors and methods of state regulation play in regional development, and also their place in socio-economic and geopolitical space. The object of the research is Kamchatka territory as the region playing strategically important role in socio-economic development of Russia and also northern territories of the other countries comparable with Kamchatka on the bass if environmental conditions such as Iceland, Greenland, USA (Alaska, Canada (Yukon, and Japan (Hokkaido. On the basis of allocation of the general signs of regional socio-economic systems and creation of the regional development models forming the basis for comparative estimates, the article analyses the territories, which are comparable on the base of climatic, geographic, economic, geopolitical conditions, but thus significantly different due to the level of economic familiarity. The generalization of the extensive statistical material characterizing various spheres of activity at these territories, including branch structure of the economy, its infrastructure security, demographic situation, the budgetary and financial sphere are given. It allows defining the crucial features of the regional economy development models. In the conclusion, the authors emphasize that ignoring of the essential relations among the regional system elements and internal and external factors deprives a research of historical and socio-economic basis.

    Full Text Available Examinations of pig blood samples have been carried out at public pig farms in three Belgrade municipalities: Palilula, Surcin and Obrenovac. The number of tested blood serums of pigs at Palilula was 18990, in Surcin 7739 and in Obrenovac it was 8200. The number of positive blood serums on leptospirosis in pigs was 760, and out of that number the most positive samples (496 were in Surcin, followed by Palilula (217, and the least were found in Obrenovac (47. In the period from 2000 to 2009, there were tested 34929 blood serums of pigs from farms located at the territory of Belgrade. For the investigations there was used the microscopic agglutination test (MAT on seven varieties of L. interrogans: L. pomona, L. icterohaemorrhagiae, L. grippotyphosa, L. sejroe, L. canicola, L. bataviae and L. australis. Seropositivity in pigs was determined in 760 blood serums, or in 2.17%. Leptospirosis prevalence was not very high, but it was constant, which indicates that leptospirosis infection maintained at the territory of Belgrade for ten years throughout our continual investigation.

  2. Living the territoriality: Mapuche tourism and development

    Full Text Available This article examines how Mapuche entrepreneurs are shaping the landscape of tourism in southern Chile in the context of indigenous development. Based on ethnographic research in and around Lican Ray, we looked at the impacts of Mapuche tourism ventures on development and deterritorialisation. Furthermore, we consider Mapuche tourism as a strategy of resistance in response to the deepening displacement of Mapuche population and the loss of traditional cultural values. The first section means to give an overview of the complexity of issues regarding (indigenous tourism and development as well as to introduce Mapuche tourism practices. Next, dealing with notions as territoriality and collectivism, we argue that Mapuche entrepreneurs are reappropriating Mapuche culture for development. Mapuche tourism is mobilising alternative ways for development, being and relating to the profound relationship they have with their territory and environment in accordance to their worldview. Finally, following the theories of anthropologists Charles Hale and James Scott, we show how Mapuche tourism is shaped in globalisation through Chile’s neoliberal policy. However, the Mapuche indigenous people active in tourism demonstrate that they possess the agency to construct strategies of ‘cultural resistance’. This article brings new perspectives to the study of indigenous tourism and development and represents Mapuche tourism as an opportunity for both indigenous development and resistance.

    Full Text Available This paper discusses the importance of aesthetic inventions on modes of youth subjectivity in the vulnerability and violence contexts. It also intends to reflect on how the actions undertaken by these youth can cut across the discussion between occupational therapy and culture. Therefore, we worked with some fragments of life stories of three young people engaged in cultural collective distinctive - marginal literature soiree, hip hop movement and audiovisual production - in the districts of Brasilândia and Vila Nova Cachoeirinha in the north of the city of São Paulo, whose we could follow through ethnographic incursions in protagonized cultural activities or in which they participate and oral history interviews. The youth subjectivities productions has been configured as a live territory marked not only by poverty and violence experiences, but, also by collective and creative productions, a brand new life style through aesthetic inventions in the periphery where the stigma of being young, negro and poor gives place to an emblem: the pride of being from the periphery. This emblematic territory is highlighted in cultural collective, particularly in Sarau Poetry Brasa and Cinescadão, two strategies of art and culture that invoke an experience resistance, transforming the experiences of violence and vulnerability that are experienced on the outskirts, in ethical, aesthetic and policies practices.

In this study we have taken into account the complex and the etymologically adequate meaning of the notion and not the meaning most commonly used at present (i.e. the functional zoning and regionalisation of the territory. Relying on the estimations of territorial surveys, one may give the solutions for the extant malfunctions and for optimising future developments. The geographic components of this parameter (the territorial survey are: the natural support basis, the population and its settlements, the social and economic development level, the technical equipment of the territory, and the extant risks and malfunctions. Indices from 1 to 10 will be summed in order to give us the big picture, namely the present-day situation and the favourability level of that territory for various anthropic interventions.

    The development in location-based mobile media has led to the popularity of its use for place experiences. This study explored the concept of territoriality, which is suggested as the underlying human behaviour that influences consumers’ mobility and experience stimulated by the social gaming...... feature of location-based media. From an exploratory investigation with a series of focus group discussions with users of location-based media, this study observed the activities of territorial tagging for the purposes of territorial claim and defence to gain and maintain the perceived territorial control...... over resources and rewards attached to certain places. The ability of location-based media to make the physical territory to interact with informational devices enables territorial behaviour to manifest in the consumption of local establishments, making location-based media a powerful tool...

    Garcia and Associates (GANDA) was contracted by the Lawrence Livermore National Laboratory (LLNL) to collect information on golden eagle (Aquila chrysaetos) use of Site 300. During 2014, we conducted surveys at Site 300 and for an area including a 10-mile radius of Site 300. Those surveys documented 42 golden eagle territories including two territories that overlapped with Site 300. These were named ‘Tesla’ and ‘Linac Road’. In 2015, we conducted surveys to refine the territory boundaries of golden eagle territories that overlapped with Site 300 and to document eagle activity at Site 300.

    2013-09-01

    Full Text Available Of late, there have been several political, practical and analytical changes to our understanding of rural development. Diverse efforts have emerged in the analysis and discussion of spatial dynamics such as “rurality”, territories, in the construction of a territorial perspective of rural development. These changes in the forms of identification and measurement of rural development lead us to question the validity and effectiveness of applied methods, inviting us to establish methodologies and analytical criteria coherent with the multiple manifestations and scales of development. This article offers a multidimensional and multi-scalar analytical model for territorial rural development, using our methodology tested in four rural territories of Brazil.

    Full Text Available In the context of transforming a part of Serbian anthropology into social theoretic management of identity, I suggest both comparative historiographic and ethnographic learning from societies with similar post-colonial experience, with the aim to include the discipline into an urgent defense of Serbia and Belgrade from further ethno-profiteering interests of elites in/from outer territories, left over on the ruins of our ill judged, resource incompatible, exaggerated or immoral twentieth century adventures. Serbian anthropology, written by anthropologists to whom Serbia and Belgrade are "homeland" by origin or civilized choice, should play the key role in the defense of Serbian citizens from the interest of elites in/from the outer "homelands", particularly by revealing the processes for which it is, as a discipline, most expert at – the professionalization of ethnicity, interactive and hybrid nature of identity, instrumental nature of tradition and the identity politics in general. Having in mind the latest attempt, a particularly successful one, conducted by the end of the 20th and the beginning of the 21st century that the lives, health, well-being, dignity and future of persons born in and loyal to the interest of Serbia and Belgrade, in large scale, thoroughly and long term be sacrificed and dedicated to the interests of ethno-profiteering elites in/from outer territories, in this article I point to the possibility to, along with the comparative learning from the above mentioned post-colonial experiences, delicate experiences of urgent anthropology be applied as well as the rich tradition of collective research. This text analyzes the results of first such research, that represenst the initial, praiseworthy and a brave step in the wise striving to engage social sciences and humanities in a search of expert and not mythical/daily-political solutions of the key problem of the Serbian nation – that of how to settle the interests of the

    1982-01-01

    Computerization can offer great advantages. But one publication ideally suited to computerization was slow to take advantage of the new technology. The main reason was reluctance to try an unfamiliar way of doing things. Having now switched to computerization, the publication has reaped many benefits. Among them: production time is faster; costs are lower; errors are fewer. Computerization has not been without minor problems. The most obvious is vulnerability to the rarity of a system failure. Others include the technology's potential reinforcement of overediting and of excessive reliance on extremely rapid response. Such problems, however, do not indicate weaknesses in the technology itself; rather, they reflect an incomplete adaption to it and the need for more realistic expectations. An unwarranted reluctance to innovate can slow advances in communication. Technical communicators must be willing to rechart their own familiar territory.

This solution allows for the open dissemination of such data. The challenge is to provide a web interface for unskilled users in order to help them understand complex information about the demographic evolution of French territories. Our approach combines interactive thematic, spatial, and temporal views. We describe our architecture, based on open-source technologies, and the organization of this imperfect geo-historical information in our spatiotemporal database. Our second contribution concerns the concept of an acquaintance graph that has been used to obtain an efficient design with good performance in our geovisualization website.

    Up until today, Malaysia has used renewable energy technology such as biomass, solar and hydro energy for power generation and co-generation in palm oil industries and also for the generation of electricity, yet, we are still far behind other countries which have started to optimize waves for similar production. Wave power is a renewable energy (RE) transported by ocean waves. It is very eco-friendly and is easily reachable. This paper presents an assessment of wave power potential in Malaysian territorial waters including waters of Sabah and Sarawak. In this research, data from Malaysia Meteorology Department (MetMalaysia) is used and is supported by a satellite imaginary obtained from National Aeronautics and Space Administration (NASA) and Malaysia Remote Sensing Agency (ARSM) within the time range of the year 1992 until 2007. There were two types of analyses conducted which were mask analysis and comparative analysis. Mask analysis of a research area is the analysis conducted to filter restricted and sensitive areas. Meanwhile, comparative analysis is an analysis conducted to determine the most potential area for wave power generation. Four comparative analyses which have been carried out were wave power analysis, comparative analysis of wave energy power with the sea topography, hot-spot area analysis and comparative analysis of wave energy with the wind speed. These four analyses underwent clipping processes using Geographic Information System (GIS) to obtain the final result. At the end of this research, the most suitable area to develop a wave energy converter was found, which is in the waters of Terengganu and Sarawak. Besides that, it was concluded that the average potential energy that can be generated in Malaysian territorial waters is between 2.8kW/m to 8.6kW/m.

    King penguins exhibit mutual color ornamentation of feathers and beak color. They breed in dense colonies and produce a single chick every 2 years. Thus, males and females must choose partners carefully to be reproductively successful, and auricular patches of males and UV coloration of beak spots have been shown to influence mate choice. Position in the breeding colony is also important to reproductive success, with pairs on the edge of the colony less successful than those in the center. We studied the mutual ornaments, individual condition, and position of pairs in their breeding colony. Males were significantly larger than females in size, body mass, and auricular patch size. Within pairs, auricular patch size of males and females were significantly correlated, and male auricular patch size and body mass were significantly associated, suggesting a link between this ornament and male body condition. Moving from the edge to the center of the colony, pairs had larger yellow-orange auricular patches, indicating a link between this ornament and settlement in higher quality territories in the center of the colony. Pairs were also less brightly brown colored on the breast and less saturated in UV color of the beak spot. Since we observed pairs that were settling for egg laying, location in the colony may have reflected aspects of pair condition, rather than later jockeying for positioning using ornaments as signals of behavioral dominance.

  4. Individual quality explains variation in reproductive success better than territory quality in a long-lived territorial raptor.

    2014-01-01

    Evolution by natural selection depends on the relationship between individual traits and fitness. Variation in individual fitness can result from habitat (territory) quality and individual variation. Individual quality and specialization can have a deep impact on fitness, yet in most studies on territorial species the quality of territory and individuals are confused. We aimed to determine if variation in breeding success is better explained by territories, individual quality or a combination of both. We analysed the number of fledglings and the breeding quality index (the difference between the number of fledglings of an individual/breeding pair and the average number of fledglings of the monitored territories in the same year) as part of a long term (16 years) peregrine falcon (Falco peregrinus) monitoring program with identification of individuals. Using individual and territory identities as correlates of quality, we built Generalised Linear Models with Mixed effects, in which random factors depicted different hypotheses for sources of variation (territory/individual quality) in the reproductive success of unique breeding pairs, males and females, and assessed their performance. Most evidence supported the hypothesis that variation in breeding success is explained by individual identity, particularly male identity, rather than territory. There is also some evidence for inter year variations in the breeding success of females and a territory effect in the case of males. We argue that, in territorial species, individual quality is a major source of variation in breeding success, often masked by territory. Future ecological and conservation studies on habitat use should consider and include the effect of individuals, in order to avoid misleading results.

    At the cusp of food production, Near Eastern societies adopted new territorial practices, including archaeologically visible sedentism and nonsedentary social defenses more challenging to identify archaeologically. New archaeological and paleoenvironmental evidence for Arabia's earliest-known sacrifices points to territorial maintenance in arid highland southern Yemen. Here sedentism was not an option prior to agriculture. Seasonally mobile pastoralists developed alternate practices to reify cohesive identities, maintain alliances, and defend territories. Archaeological and paleoenvironmental evidence implies cattle sacrifices were commemorated with a ring of more than 42 cattle skulls and a stone platform buried by 6,400-year-old floodplain sediments. Associated with numerous hearths, these cattle rites suggest feasting by a large gathering, with important sociopolitical ramifications for territories. A GIS analysis of the early Holocene landscape indicates constrained pasturage supporting small resident human populations. Cattle sacrifice in southern Arabia suggests a model of mid-Holocene Neolithic territorial pastoralism under environmental and cultural conditions that made sedentism unsusta

    Directory of Open Access Journals (Sweden)

    Fabiana D'Ascenzo

    2013-02-01

    Full Text Available The peripheral and segmented nature of the urban network and communication routes in the Democratic Republic of Congo condemns the country to being outwardoriented, allowing little room for integration of national territory and favouring the neighbouring inter-African context. In this situation, the city of Kinshasa is forced to carry not just the weight of its role as capital city but also the burden associated with a territorial expansion that has occurred very much in the post-Independence style, where a veritable territorial implosion has resulted due to the existence of an inward-looking system of relationships. Based on field work, this article discusses the spatial factors existing in the social context under consideration, and identifies, as a result of the interaction of those factors, a complex territoriality that affects all the various facets of the urban fabric. Key words: Kinshasa, urban organisation, spatial expansion, imploded territoriality, peripheral urbanisation, outwardoriented relationships.

  9. Everyday territories: homelessness, outreach work and city space.

    Smith, Robin James; Hall, Tom

    2017-07-18

    This article develops a situational approach to understanding urban public life and, in particular, the production of urban territories. Our aim is to examine the ways in which city space might be understood as comprising multiple, shifting, mobile and rhythmed territories. We argue that such territories are best understood through attending to their everyday production and negotiation, rather than handling territory as an a priori construct. We develop this argument from the particular case of the street-level politics of homelessness and street care. The experience of street homelessness and the provision of care in the public spaces of the city is characterised by precarious territorial claims made and lost. We describe some of the ways in which care work with rough sleepers is itself precarious; 'homeless', in lacking a distinct setting in which it might get done. Indeed, outreach work takes place within and affirms homeless territories. The affirmation of territory is shown to be central to the relationship developed between the workers and their rough sleeping clients. We also show, however, the ways in which outreach workers operate on territory not their own, twice over. Outreach work is precarious in that it is practised within, and can run counter to, other territorial productions in which the experience of urban need and the work and politics of care are entangled. In sum, this article aims to move beyond static and binary understandings by developing a mobile and situational approach to city space which recognises the intensive yet overlooked work of territorial production. © London School of Economics and Political Science 2017.

    Full Text Available La diversidad de las regiones europeas, exige asumir una perspectiva territorial, que no se debe considerar simplemente como un obstáculo en el camino de la cohesión, sino como un valor añadido que potencia el desarrollo económico y enriquece la convivencia comunitaria. La UE, desde su inicio, intenta superar estas disparidades. En este trabajo se analiza el proceso de incorporación del discurso territorial en el seno de la UE que se plasma en la Estrategia Territorial Europea de los 90, posteriormente, ya en pleno Siglo XXI, se desarrolla la Agenda Territorial y se publica el Libro Verde de la cohesión territorial como hitos más relevantes de este proceso. La evolución tanto del propio concepto de cohesión territorial como de las acciones comunitarias en el ámbito territorial, se han incorporado paulatinamente a la estrategia de desarrollo de la UE, que se plasma en la vigente «Europa 2020», y en último extremo pone en evidencia la necesidad de implementar la dimensión territorial en el conjunto de políticas de la UE, aunque con distinto nivel de implicación.

Regions of development 3 (South, 4 (South-West and 8 (Bucharest-Ilfov" elaborated during 2004 – 2006, within the AMTRANS programme funded by the Ministry of Education and Research, coordinated by INCD – URBANPROIECT in partnership with the Institute of Geography of the Romanian Academy and the Qualification in Statistics National Centre. The general objective of the project was sustainable and balanced spatial development of the settlement network and promotion of new relationships between urban and rural. Concretely, the study has produced a model of a polycentric and balanced settlement network according to the European principles. The case study testing and validating this model took place in southern Romania, territory exhibiting acutely the entire range of problems related to the state of the settlement network: profoundly large rural areas, accentuated dynamics of declaring new cities without sufficient evidence, excessive polarization exercised by Bucharest, etc. The paper presents the intervention directions needed to balance in the territory urban poles within the studied area, focusing on the establishment of orientation policies to consolidate the role of each settlement based on the hierarchical level of importance: European, national, regional, and local. The paper also identifies possible functional urban areas: the metropolitan area of Bucharest, areas of potential strategic integration, areas of cooperation between the small and medium-sized cities and the rural regions. Within each of these areas, the paper proposes to establish new relationships between urban and rural based on partnership, involving cooperation and coordination in achieving common goals.The study considers that the poles of development are the key element of proposed model, and their identification, formation, and balanced distribution

    Full Text Available The safety of the territory and the environment is a theme much discussed, but often not in organic and competent way. PLINIVS study centre has been studying for several years the impact of potentially disastrous events on the territory and has produced analysis models and scenery simulation of main natural risks regarding Campania territory (seismic, hydrogeological, volcanic, meteo-marine risks, etc.. Knowing the risk, and quantifying it, is important in order to single out critical aspects of the territory (threats and to intervene through mitigation measures and eventually a modern Plan of Civil Protection. Therefore the plan becomes a dynamic process able to control rhythmically the state of the risk and the safety level of the territory, and spatial planning should avail itself of the fundamental contribution of knowledge offered by these tools.

  13. Simulation study of territory size distributions in subterranean termites.

    2011-06-21

    In this study, on the basis of empirical data, we have simulated the foraging tunnel patterns of two subterranean termites, Coptotermes formosanus Shiraki and Reticulitermes flavipes (Kollar), using a two-dimensional model. We have defined a territory as a convex polygon containing a tunnel pattern and explored the effects of competition among termite territory colonies on the territory size distribution in the steady state that was attained after a sufficient simulation time. In the model, territorial competition was characterized by a blocking probability P(block) that quantitatively describes the ease with which a tunnel stops its advancement when it meets another tunnel; higher P(block) values imply easier termination. In the beginning of the simulation run, N=10, 20,…,100 territory seeds, representing the founding pair, were randomly distributed on a square area. When the territory density was less (N=20), the differences in the territory size distributions for different P(block) values were small because the territories had sufficient space to grow without strong competitions. Further, when the territory density was higher (N>20), the territory sizes increased in accordance with the combinational effect of P(block) and N. In order to understand these effects better, we introduced an interference coefficient γ. We mathematically derived γ as a function of P(block) and N: γ(N,P(block))=a(N)P(block)/(P(block)+b(N)). a(N) and b(N) are functions of N/(N+c) and d/(N+c), respectively, and c and d are constants characterizing territorial competition. The γ function is applicable to characterize the territoriality of various species and increases with both the P(block) values and N; higher γ values imply higher limitations of the network growth. We used the γ function, fitted the simulation results, and determined the c and d values. In addition, we have briefly discussed the predictability of the present model by comparing it with our previous lattice model

  14. Supplementation of male pheromone on rock substrates attracts female rock lizards to the territories of males: a field experiment.

    Directory of Open Access Journals (Sweden)

    José Martín

    Full Text Available Many animals produce elaborated sexual signals to attract mates, among them are common chemical sexual signals (pheromones with an attracting function. Lizards produce chemical secretions for scent marking that may have a role in sexual selection. In the laboratory, female rock lizards (Iberolacerta cyreni prefer the scent of males with more ergosterol in their femoral secretions. However, it is not known whether the scent-marks of male rock lizards may actually attract females to male territories in the field.In the field, we added ergosterol to rocks inside the territories of male lizards, and found that this manipulation resulted in increased relative densities of females in these territories. Furthermore, a higher number of females were observed associated to males in manipulated plots, which probably increased mating opportunities for males in these areas.These and previous laboratory results suggest that female rock lizards may select to settle in home ranges based on the characteristics of scent-marks from conspecific males. Therefore, male rock lizards might attract more females and obtain more matings by increasing the proportion of ergosterol when scent-marking their territories. However, previous studies suggest that the allocation of ergosterol to secretions may be costly and only high quality males could afford it, thus, allowing the evolution of scent-marks as an honest sexual display.

  15. Health inequity in the Northern Territory, Australia

    Science.gov (United States)

    2013-01-01

    Introduction Understanding health inequity is necessary for addressing the disparities in health outcomes in many populations, including the health gap between Indigenous and non-Indigenous Australians. This report investigates the links between Indigenous health outcomes and socioeconomic disadvantage in the Northern Territory of Australia (NT). Methods Data sources include deaths, public hospital admissions between 2005 and 2007, and Socio-Economic Indexes for Areas from the 2006 Census. Age-sex standardisation, standardised rate ratio, concentration index and Poisson regression model are used for statistical analysis. Results There was a strong inverse association between socioeconomic status (SES) and both mortality and morbidity rates. Mortality and morbidity rates in the low SES group were approximately twice those in the medium SES group, which were, in turn, 50% higher than those in the high SES group. The gradient was present for most disease categories for both deaths and hospital admissions. Residents in remote and very remote areas experienced higher mortality and hospital morbidity than non-remote areas. Approximately 25-30% of the NT Indigenous health disparity may be explained by socioeconomic disadvantage. Conclusions Socioeconomic disadvantage is a shared common denominator for the main causes of deaths and principal diagnoses of hospitalisations for the NT population. Closing the gap in health outcomes between Indigenous and non-Indigenous populations will require improving the socioeconomic conditions of Indigenous Australians. PMID:24034417

    Unglaciated parts of the Yukon constitute one of the most important areas in North America for yielding Pleistocene vertebrate fossils. Nearly 30 vertebrate faunal localities are reviewed spanning a period of about 1.6 Ma (million years ago) to the close of the Pleistocene some 10 000 BP (radiocarbon years before present, taken as 1950). The vertebrate fossils represent at least 8 species of fishes, 1 amphibian, 41 species of birds and 83 species of mammals. Dominant among the large mammals are: steppe bison ( Bison priscus), horse ( Equus sp.), woolly mammoth ( Mammuthus primigenius), and caribou ( Rangifer tarandus) - signature species of the Mammoth Steppe fauna ( Fig. 1), which was widespread from the British Isles, through northern Europe, and Siberia to Alaska, Yukon and adjacent Northwest Territories. The Yukon faunas extend from Herschel Island in the north to Revenue Creek in the south and from the Alaskan border in the west to Ketza River in the east. The Yukon holds evidence of the earliest-known people in North America. Artifacts made from bison, mammoth and caribou bones from Bluefish Caves, Old Crow Basin and Dawson City areas show that people had a substantial knowledge of making and using bone tools at least by 25 000 BP, and possibly as early as 40 000 BP. A suggested chronological sequence of Yukon Pleistocene vertebrates ( Table 1) facilitates comparison of selected faunas and indicates the known duration of various taxa.

  17. The territorial-environmental perception in fishing zones

    2007-12-01

    Full Text Available Geography was always concerned with the study of the relationship between social groups and the environment in which they interact as natural resources for their survival. This relationship was always intertwined by power determinations in the organization of forms of appropriation of natural resources, deriving different types of territorial assets. These territorial assets demonstrate a variety of actors, involved in a certain territory and materializing different actions for the appropriation of space and use of the natural resources. In the case of fishing this is not different, since we verified that fishing practice is witnessed by a variety of actors, fishermen, fishing community, fishing association, fishing zone and regulatory agencies. Each of these actors relate in specific ways to the fishing spaces and material specific actions to define the territory, adopting territorial assets and a diversity of perceptions which sometimes conflict to each other. This study is part of a research which, through direct field research, aims at accomplishing an analysis of the way of life of the fishermen of the Colony of Fishermen Z 62, headquartered in the municipal district of Breves, state of Pará, and of how they acknowledge their territory, in the way they interact with other actors which use the same territory in other ways unrelated to fishing.

  18. A territorial understanding of sustainability in public development

    Energy Technology Data Exchange (ETDEWEB)

    Peti, Marton, E-mail: mpeti@vati.hu

    2012-01-15

    Sustainability theories in European Union (EU) development policies are facing significant challenges: it is difficult to transmit context-specific, publicly communicable messages; the recent development policies strengthen the concurrent development paradigm of economic growth and competitiveness; 'climate change' became a more popular environmental integration term than sustainability in the last few years. However, due to the recent crises of the economic growth, there is a great chance to reintroduce a sustainability-based development. A territorial/regional understanding of sustainability can also be an answer for the current challenges, a platform for refreshing the concept with relevant, specific messages that are close to the everyday life. This paper summarises the 'territorial system'-based basic principles of territorial sustainability in a model called AUTHARSIIV (AUTonomy, HARmony, Solidarity, Innovation, Identity and Values). This is a supplementary sustainability content specified for the context of spatial/regional development or planning. The paper also examines the presence of 'general and territorial sustainability' in regional development programmes, and case studies on applying the territorial sustainability principles in planning, assessment, and implementation. According to the results, sustainability is rarely adapted to the conditions of a given sector or a region, and the territorial aspect of sustainability is underrepresented even in territorial programmes. Therefore, the paper proposes a new planning and assessment system that is based on a set of regionally legitimate sustainability values.

  19. Association, property, territory: What is at stake in immigration?

    2017-01-01

    Full Text Available It is often claimed that states have territorial rights, and that these rights include the right to exclude people who seek admission to their territory. In this paper I will examine whether the most defensible account of territorial rights can provide support to the right to exclude. I will discuss three types of theories of territorial rights. The first account links the right of states to exclude to the prior right of individuals to freedom of association, which is said to include the right not to associate and to dissociate. The second is a Lockean theory that grounds the territorial rights of states, and hence their right to exclude, in the prior right of individuals to private property in the land that constitutes the territory of the state. I argue that these accounts have independently implausible implications, regardless of their implications for the immigration debate. The third account is a Kantian theory that bases the territorial jurisdiction of states on individuals’ duty to create, sustain and submit themselves to a shared system of law that is a necessary condition of guaranteeing their rights and of discharging their duties towards one another. I will argue that the Kantian account is superior to its current alternatives. However, I also suggest that it cannot ground a broad right to exclude.

  20. Territorial Identity and Grassroots Economic Activism: The Politicization of Farmers’ Mobilizations in the French Basque Country

    2015-07-01

    Full Text Available The French Basque Country (FBC represents an emblematic case of the politicization of local development through grassroots economic activism. These mobilizations are particularly obvious in the agricultural sector. Based on a qualitative research on small farmers’ organizations and short food circuits, this article shows that Basque farmers’ mobilizations constitute a case of a dual politicization of small-scale farming and territorial identity. This process has gone through two phases: the first period (1970-2000 was characterized by the politicization of local productive systems. Throughout the decade 2000-2010, a new mode of grassroots economic activism emerged, signalled by new alliances between producers and consumers, and by an increasing ideological pluralism. Two case studies illustrate these developments. The first relates to a case of explicit politicization with the controversy around the foundation in 2005 of an alternative Basque Chamber of Agriculture. The second case study is devoted to the development of short food circuits in the FBC, considered here as a case of implicit politicization of the encounter between productive and consumption circuits. Both cases illustrate the politicization of new economic social movements, and the constant overlapping of sectoral and territorial claims in the Basque territory.

    Climate change is one of the key environmental, social and economical issues, and it is also followed by political consequences. Impact of climate conditions on countries' economy is increasingly recognized, and a lot of attention is given, both in the global scale and by the individual national governments. In years 2008-2010, at the Poland -Institute of Meteorology and Water Management-National Research Institute was realized the KLIMAT Project on Impact of climate change on environment, economy and society (changes, effects and methods of reducing them, conclusions for science, engineering practice and economic planning) No. POIG01-03-01-14-011/08. The project was financed by the European Union and Polish state budget in frame of Innovative Economy Operational Programme. A very wide range of research was carried out in the different thematic areas. One of them was "Natural disasters and internal safety of the country (civil and economical)." The problem of drought in Poland was developed in terms of meteorology and hydrology. "Proxy" Data Descriptions very often inform about dry years and seasons, hot periods without precipitation. Analysis of historical material allowed to extract the years that have experienced prolonged periods of high temperatures and rainfall shortages. Weather phenomenon defined as drought belongs to extreme events. This information was very helpful in the process of indexing and thus to restore the course and intensity of climatic elements in the past. The analysis covered the period from year 1000 to modern times. Due to the limited information from the period of 1000-1500 the authors focused primarily on the period from 1500 to 2010. Analysis of the collected material has allowed the development of a highly precise temporal structure of the possible occurrence of dry periods to Polish territory.

    Several research efforts have coordinated the academic program of Agricultural Business Management from the University De La Salle (Bogota D.C., to the design and implementation of a sustainable agribusiness model applied to food development, with territorial projection. Rural development is considered as a process that aims to improve the current capacity and potential of the inhabitant of the sector, which refers not only to production levels and productivity of agricultural items. It takes into account the guidelines of the Organization of the United Nations “Millennium Development Goals” and considered the concept of sustainable food and agriculture development, including food security and nutrition in an integrated interdisciplinary context, with holistic and systemic dimension. Analysis is specified by a model with an emphasis on sustainable agribusiness production chains related to agricultural food items in a specific region. This model was correlated with farm (technical objectives, family (social purposes and community (collective orientations projects. Within this dimension are considered food development concepts and methodologies of Participatory Action Research (PAR. Finally, it addresses the need to link the results to low-income communities, within the concepts of the “new rurality”.

    Full Text Available In this paper we focus on the structure and territorial borders of the Baltic Sea region, and examine the key structural elements of the transnational territorial transport system. In this respect, we clarify some terms used in transport geography. For the first time the transport system gets territorially localized, which allows for a broad range of new studies of transnational transportation in the Baltic Sea area. We also identify the main principles of development and operation of international territorial transport systems and present them taking the Baltic Sea region as an example. Our findings, we hope, will have a great practical application for researchers of transport geography, especially those studying international logistics.

    There is currently a noticeable change in public health policy, as well as a paradigm shift with the policy of a mental health territory. From a humanist sector policy, centred on the patient, we are moving towards a policy of a mental health territory, which, although taking into account the changing needs of a group of people, no longer considers the specific needs of the individual. The notion of a geographic breakdown of the organisation of care is becoming predominant.

    Full Text Available The consideration in this paper is given to innovative model of development of traditionally industrial territories. We emphasize the following basic approaches to the employment of innovative potential of territories: diversification and restructuring of local economy, integration and disintegration of life-sustaining activity of neighboring territories, progressive economic advance, as well as simultaneous combination of several approaches (mixed model. Progressive model of development is sufficiently popular and is related tothe increasing already existing potential of territories. In practice,it doesn’t generally suppose essential changes in sectoral structure of local economy and means developing existing productions and spheres of activity of territory. Mixed model of structural transformations is characterized through the fact, that it supposes simultaneous use of different elements from the models counted. It allows: firstly, to adopt in a bigger extent a complex of measures to conditions of certain territory; secondly, to take into account a broader range of exogenous and endogenous factors; thirdly, to raise the effectiveness of the program of structural transformations being realized

    Full Text Available The present article argues that the territorial planning is nowadays fundamental instrument to the definition of strategic areas of opportunity, and also, articulating instrument of distinct territory scales (from local to regional. It is restored the importance of distinct levels of planning, listed in chain, of a more general level of regional coverage to specific and local levels. It is demonstrated the importance of this articulation not only for dealing with urgencies in the intra-urban territory ordering to promote the compact city, but also, to develop cities and regions, enhancing the implementation of decentralized and solidary supply chains that characterize a network organization. It is proposed that, the planning instruments and strategic ordering of the territory, aimed at decentralization and creation of new towns or focusing on the redevelopment and recycling of uses and activities in cities and regions in decline with degraded areas, allowing decisions of strategic importance that determine lines, axes and opportunity areas, targets of economic, and social development, and therefore it starts to concentrate investment in infrastructure, serving to enhance the implementation of urban network centers and supply chains, which benefits with the larger planning of urban and regional territory. Because of it, the analysis object is the strategic territorial planning that has been developed and implemented specifically in Spain, underlying plans and actions of urban regeneration, as exemplified by the process is still ongoing in the city of Bilbao, the region north of the country.

    Full Text Available This article considers the main features of sustainable development of rural territories, identifies the factors of innovative entrepreneurship, and assesses their influence on the condition of rural economy. Special attention is paid to the analysis of concepts, programmes, and projects in the field of rural territory development. The authors summarise conceptual and strategic approaches and actions of the Baltic region states in the field of sustainable development of rural territories. The article identifies objectives, common for the Baltic region, relating to sustainability of rural territories, including sustainable use of natural resource potential, diversification of production through support for non-agricultural activities and employment, application of innovations and efficient technologies, and manufacturing of environmentally friendly products. The analysis of the development of agricultural and innovations in the Baltic Sea regions serves as a basis for identifying the factors and conditions of supporting innovative entrepreneurship. Of special importance are the research, technological, and innovative potential of the territory, the availability of adequate innovative infrastructure, and the formation of innovative culture. The authors corroborate the idea of innovative entrepreneurship development in rural territories through the transformation of organizational and economic mechanism of management relating to the creation of institutional, infrastructure, and spatial conditions. Research and technological cooperation in the Baltic region is emphasised as a priority area.

    Background: Whole body vibration (WBV) exercise has been used in health sciences. Authors have reported that changes on the concentration of plasma biomarkers could be associated with the WBV effects. The aim of this investigation is to assess the consequences of exposition of 25 Hz mechanical vibration generated in oscillating/vibratory platform (OVP) on the concentration of some plasma biomarkers and on the weight of rats. Materials and Methods: Wistar rats were divided into two groups. The animals of the Experimental Group (EG) were submitted to vibration (25 Hz) generated in an OVP with four bouts of 30 seconds with rest time of 60 seconds between the bouts. This procedure was performed daily for 12 days. The animals of the control group (CG) were not exposed to vibration. Results: Our findings show that the WBV exercise at 25 Hz was not capable to alter significantly (p<0.05) the weight of the rats. A significant alteration in the concentrations of amylase was found. Conclusion: Our results indicate a modulation of the WBV exercise with vibration of 25 Hz of frequency (i) in the pathways related to the weight and (ii) in the concentration of some biomarkers, such as amylase.

    2015-01-01

    Full Text Available Osteoporosis can be associated with the disordered balance between osteogenesis and adipogenesis of bone marrow-derived mesenchymal stem cells (BM-MSCs. Although low-frequency mechanical vibration has been demonstrated to promote osteogenesis, little is known about the influence of acoustic-frequency vibratory stimulation (AFVS. BM-MSCs were subjected to AFVS at frequencies of 0, 30, 400, and 800 Hz and induced toward osteogenic or adipogenic-specific lineage. Extracellular matrix mineralization was determined by Alizarin Red S staining and lipid accumulation was assessed by Oil Red O staining. Transcript levels of osteogenic and adipogenic marker genes were evaluated by real-time reverse transcription-polymerase chain reaction. Cell proliferation of BM-MSCs was promoted following exposure to AFVS at 800 Hz. Vibration at 800 Hz induced the highest level of calcium deposition and significantly increased mRNA expression of COL1A1, ALP, RUNX2, and SPP1. The 800 Hz group downregulated lipid accumulation and levels of adipogenic genes, including FABP4, CEBPA, PPARG, and LEP, while vibration at 30 Hz supported adipogenesis. BM-MSCs showed a frequency-dependent response to acoustic vibration. AFVS at 800 Hz was the most favorable for osteogenic differentiation and simultaneously suppressed adipogenesis. Thus, acoustic vibration could potentially become a novel means to prevent and treat osteoporosis.

    2010-06-01

    Full Text Available The environment can impose strong limitations on the efficacy of signal transmission. In particular, for vibratory communication, the signaling environment is often extremely heterogeneous at very small scales. Nevertheless, natural selection is expected to select for signals well-suited to effective transmission. Here, we test for substrate-dependent signal efficacy in the wolf spider Schizocosa stridulans Stratton 1991. We first explore the transmission characteristics of this important signaling modality by playing recorded substrate-borne signals through three different substrates (leaf litter, pine litter, and red clay and measuring the propagated signal. We found that the substrate-borne signal of S. stridulans attenuates the least on leaf litter, the substrate upon which the species is naturally found. Next, by assessing mating success with artificially muted and non-muted males across different signaling substrates (leaf litter, pine litter, and sand, we explored the relationship between substrate-borne signaling and substrate for mating success. We found that muted males were unsuccessful in obtaining copulations regardless of substrate, while mating success was dependent on the signaling substrate for non-muted males. For non-muted males, more males copulated on leaf litter than any other substrate. Taken together, these results confirm the importance of substrate-borne signaling in S. stridulans and suggest a match between signal properties and signal efficacy – leaf litter transmits the signal most effectively and males are most successful in obtaining copulations on leaf litter [Current Zoology 56 (3: 370–378, 2010].

    Full Text Available The Territories of Citizenship Program aims to strengthen small-scale farmers in Brazil by financing productive projects and infrastructures defined within deliberative institutional arrangements which is implementing the so-called “cycle of social management”. It presupposes dialectic active and progressive between the social capital of the territory, collective participation and project implementation, resulting in a virtuous process and sustainable rural development. The Territory of Borborema, in the state of Paraiba, was created in 2003 with a high level of social capital and one process of consolidation ofpeasant social movements and agroecological transition. However it does not show a good performance in terms of implementation of investment projects. This paper analyse this apparent paradox making relationship between the ideology of the government and the practice of social actors within the territorial device.

    Full Text Available The paper shows that the traditional outlook on development of territories as the process of alignment of their socio-economic development with the help of external influences should be advanced and replaced by a new vision. The purpose of the work is the definition of the basic rules of the concept of vital stability of territories. The creation by the local population of the riches and well being by expansion of manufacturing industry on the basis of the use of intelligence — technological and moral — ethical factors are shown as the basic contents of the offered concept. A consequence of such approach is the growing feedback of made expenses, as technologically completed production will be realized but not raw material or semi-finished item. Only the differentiation industrial development of the territory is capable to deduce it from a condition of poverty and depression. The understanding of development of the territory as creation of conditions for growth of people’s wellbeing and formation of a man as a person is opened. The accent of the attention on the promotion of a man not only as the purpose of transformation of territory, but also as the factor of its safe development through an increase of his or her intellectual and spiritual levels is made. The measures and instruction on innovation to the strengthening of vital stability of territories are offered. The separate results of research were used at the prolongation of the Plan for strategic development of Yekaterinburg up to 2020. Authorities of territories at the formation of their development strategy can apply the new offered rules.

  6. Resetting Wave Forms in Dictyostelium Territories

    Lee, Kyoung J.; Goldstein, Raymond E.; Cox, Edward C.

    2001-08-06

    The mechanism by which spiral wave patterns appear in populations of Dictyostelium was probed experimentally by external chemical perturbation. Spiral waves, which often arise from the breakup of circular waves driven by pacemakers, typically entrain those pacemakers. We studied these processes by resetting the waves with a spatially uniform pulse of extrinsic cyclic AMP. A pattern of spirals reappeared if resetting was early in the signaling stage, but only targets emerged following late resetting, in a manner analogous to cardiac defibrillation. This supports recent hypotheses that wave pattern selection naturally occurs by slow temporal variation of the excitability of the cells.

    2014-11-01

    Full Text Available Territorial development is a central topic within the European Union's Cohesion Policy and an important pillar for its agenda for employment and growth. To this end, the EU deploys important resources, be it in the form of dedicated programs (e.g. urban development, be it through introducing a territorial dimension to many other areas of intervention (e.g. transport policy, environmental policy, energy policy etc.. Given the high diversity of approaches, developing an integrated territorial development model becomes crucial in terms of effectiveness and efficiency. The aim of this paper is to have a closer look at various attempts to define the dimensions of an integrated territorial development model. Meanwhile, our study is meant to assess the level of integration in the use of structural funds 2007 - 2014 at the municipality level in Romania. We therefore operationalize the integrated approach as the capacity of a territory to attract funds from various programmes, as well as to involve various actors in this process. Using the number of projects attracted by public authorities, companies and NGOs from five operational programmes financed through stuctural funds 2007-2014, we developed an index that allows comparisons in the performances of Romanian municipalities. Conclusions are meant to highlight the benefits of integration and future prospects for the next programming period (2014 - 2020.

  9. The city, territoriality and networks in mental health policies

    2014-09-01

    Full Text Available The understanding of territory, made evident by a decentralized, local based, and non-institutionalized mental health model, is a fundamental element in building a renewed network. The objective of this essay is to understand how mental health policies gradually favor local actions, organized in terms of territories, to develop strategies of care that support the new model of mental health. From this perspective, the aim of this research is to reflect on the possibilities of establishing new social relations that can, in fact, widen the sense of community belonging in the daily living of those presenting mental health conditions. This study draws from theoretical concepts and frameworks of the social sciences, describing the diverse positions held by the main schools of urban sociology with regards to the understanding of territories. The multiple conceptions of territories and their relations to mental health are analyzed. Historical data about mental health in Brazil show a heterogeneous development of mental health policies in different areas of the country. Finally, social inclusion in the cities depends on an effective expansion of territory-based mental health services, as well as an amplification of the access to consumer goods and services not necessarily connected to health care, but to basic social and civil rights. Hopefully, new rules of social interaction will not be restricted to the mental health universe, but will promote new encounters in the urban space, with respect for differences and appreciation of diversity.

    While factors including remoteness, alcohol consumption, age and Indigenous ethnicity are well-documented associations of trauma mortality, less is known of trauma seasonality. This is particularly relevant to Australia's Northern Territory, with its tropical regions experiencing a climate of wet (hot and humid) and dry (warm) seasons annually. The aim of this study was to therefore, examine the characteristics of trauma mortality in the Top End, Northern Territory, Australia. A retrospective review of the National Coroners Information System (NCIS) database from 1 January 2003 to 31 December 2007 analysed four-hundred and sixteen traumatic deaths where the trauma event and death occurred within the Top End of the Northern Territory. The annual traumatic death rate for the Top End was 58.7 per 100 000, with variance between regions (accessible 38.1; remote 119.1 per 100000, respectively). Overall alcohol was involved in 56.5% of cases. The three most frequent mechanisms of death were suicide, transport related and assault, accounting for 81.5% of deaths. These respective mechanisms of death demonstrated seasonal influence, with transport related deaths 2.5 times more likely to occur in the dry than the wet season (p Territory were evident, with contrasting seasonal and regional profiles. Based upon the data of this investigation, existing programmes to minimise trauma in the Northern Territory ought to be evaluated for seasonal and regional specificity.

  11. Contested Territories: Water Rights and the Struggles over Indigenous Livelihoods

    Directory of Open Access Journals (Sweden)

    Rutgerd Boelens

    2012-11-01

    Full Text Available This paper examines the threats to Indigenous water rights and territories in the Andean countries. It analyzes how water and water rights are embedded in Indigenous territories, and how powerful actors and intervention projects tend to undermine local societies and indigenous livelihoods by developing large-scale water infrastructure. Three cases illustrate the encroachment process. In Colombia, the Embera Katio people’s water territory is colonized by a large-scale hydropower development project. In Ecuador, large-scale drinking water development for megacities aims the water belonging to the Oyacachi community’s indigenous highland territory. In Peru, communal water rights of the Colca Valley indigenous peasantry are under threat because of large-scale irrigation development. As the cases show, Indigenous peoples and communities actively contest the undermining and subordination of their water and territorial rights through a myriad of multi-scalar livelihood defense strategies. The challenges that indigenous peoples face to defend their water-based livelihoods are, however, enormous and growing every day.

  12. Causes and consequences of song amplitude adjustment in a territorial bird: a case study in nightingales

    Directory of Open Access Journals (Sweden)

    Brumm Henrik

    2004-01-01

    Full Text Available Vocal amplitude, one of the crucial factors for the exchange of acoustic signals, has been neglected in studies of animal communication, but recent studies on song variation in Common Nightingales Luscinia megarhynchos have revealed new insights into its importance in the singing behavior of territorial birds. In nightingales song amplitude is not maximized per se, but is individually regulated according to the level of masking background noise. Also, birds adjust their vocal intensity according to social variables, as in male-male interactions. Moreover, during such interactions, males exploited the directionality of their songs to broadcast them in the direction of the intended receivers ensuring the most effective signal transmission. Studies of the development of this typical long-range signaling suggest that sound level is highly interrelated with overall developmental progression and learning, and thus should be viewed as an integral part of song ontogeny. I conclude that song amplitude is a dynamic feature of the avian signal system, which is individually regulated according to the ecological demands of signal transmission and the social context of communication.

    2016-11-01

    Full Text Available Australia’s three small off-shore island territories – Norfolk Island in the Pacific Ocean and Christmas Island and the Cocos (Keeling Islands Group in the Indian Ocean – can be seen as monuments to 19th century British-style colonization, though their early paths to development took very different courses. Their transition to the status of external territories of the Australian Commonwealth in the 20th century – early in the case of Norfolk and later in the cases of Christmas and Cocos – put them on a common path in which serious tensions emerged between local populations which sought autonomous governance and the Commonwealth government which wanted to impose governmental systems similar to those applying to mainstream Australians. This article explores the issues involved, and seeks to relate the governmental history of the three island territories to the exploration of island jurisdictions developed in island studies research.

  14. Constitutionalism, State and territory in the globalization context

    William Guillermo Jiménez

    2012-12-01

    Full Text Available Globalization shows that the national State is losing the monopoly in the production of law, and this generates changes concerning the environment of application of the state legal arrangements and the role of the territory as the limit thereof. The object of this work is to offer a panorama about of the law globalization impacts on the State, the constitutional theory and the territory. The study is performed by means of the documentary review technique by using the consultation of diverse sources. Our conclusion is that the Westphalian model of State-nation has been weakened; however, globalization needs the State to be able to operate. Law has been deterritorialized and the territory continues to be a fundamental element for the contemporary State.

    Mukambayev, Aidyn; Mikhailova, Natalia

    2015-04-01

    The Central Asia territory includes the territory of five post-Soviet countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Every country has its own independent network of seismic observations and Data Processing Center aimed at every day seismic monitoring of one country territory. However, seismic hazard of Central Asia territory is stipulated by one geodynamic system that generates simultaneous large earthquakes on the territory of different countries. Thus, it is necessary to observe seismic situation for the whole region for emergency situations and for compilation of joint seismic bulletins of Central Asia region. A new contemporary network of seismic observations operated by the Institute of Geophysical Researches has been installed in Kazakhstan during last 15 years. Mainly, these are seismic arrays located throughout the country perimeter. The arrays were constructed under support of the CTBTO, and AFTAC. There are also IRIS and CAREMON stations. All data arrive to KNDC (Kazakhstan National Data Center) in real time mode. In addition, KNDC receives data in real time from stations Zalesovo (Russia), Alibek (Turkmenistan), Ala-Archa and Tokmak (Kyrgyzstan). Arrival times in the form of tables are received with 24-hours delay from almost 20 Kazakhstan stations belonging to SEME MES RK. This observation system allows monitoring the Central Asian seismicity by earthquakes with representative magnitude more than 3.5. In some regions, the events with magnitude 1.5 are recorded. As result, different products with different operativity are created for Central Asia territory: -bulletin of urgent alerts; -automatic seismic bulletin; -interactive seismic bulletin; -joint seismic operative bulletin by data arrived on-line and in table form. After that, in retrospective mode, the events nature is identified to discriminate mining explosions (up to 4000 per year) and natural earthquakes (up to 15000 per year). The results are available at KNDC web

    Full Text Available All processes that take place in nature need energy. As a consequence of the irreversibile processes development in the environment, an increase of entropy takes place. The biologists consider that biological territorial systems, unlike the non-biological ones, have an anti-entropic behaviour, due to the receiving energy from outside the system, namely solar radiation converted in chemical energy by photosynthesis. Also, some non-biological territorial systems, like the hydrological cycle for instance, develop continuously due to the receiving of energy from Sun. In this cycle the water is eliminatedas vapours with high entropy and the system receives liquid (or solid water with low entropy; this fact prevents from reaching the stage of maximum entropy. The hydrological cycle has, therefore,an anti-entropic behaviour. Nevertheless, there are differences between non-biological and biological territorial systems. In the non-biological territorial systems only conversions of mechanical into caloric energy take place, usually without stocking of energy. The biological territorial systems on the other hand are characterized by various conversions of energy (caloric, chemical, mechanical, biological or vital, noesic, by stocking of energy that is necessary for the functioning of the system and the creation of order, which makes up the premise for development. The soil territorial systems have also an anti-entropic behaviours due to both accumulation/decomposition of organic matter in the framework of the biological cycle and water evaporation/atmospheric precipitations in the framework of the hydrological cycle, cycles that take place in the soil cover under the influence of the solar energy contribution.

    Directory of Open Access Journals (Sweden)

    Marta Arretche

    Full Text Available The study explores the relationship between federalism and territorial inequality, taking Brazil as the object of analysis. The conclusion is that there is a trade-off between territorial inequality reduction and the full autonomy of local governments. The central government's redistributive role seems to be a condition for reducing revenue inequality between jurisdictions, and so reducing inequality in citizens' access to public services requires the central government to perform redistributive and regulatory role. On the other hand, local autonomy pushes toward inequality. Hence, federal regulation and local autonomy are combined in a given polity, the result tends to be bound inequality.

    Animals communicate by exchanging signals frequently in the proximity of other conspecifics that may detect and intercept signals not directed to them. There is evidence that the presence of these bystanders modulates the signaling behavior of interacting individuals, a phenomenon that has been named audience effect. Research on the audience effect has predominantly focused on its function rather than on its proximate mechanisms. Here, we have investigated the physiological and neuromolecular correlates of the audience effect in a cichlid fish (Mozambique tilapia, Oreochromis mossambicus). A male was exposed to a territorial intrusion in the presence or absence of a female audience. Results showed that the presence of the female audience increased territorial defense, but elicited a lower androgen and cortisol response to the territorial intrusion. Furthermore, analysis of the expression of immediate early genes, used as markers of neuronal activity, in brain areas belonging to the social decision-making network (SDMN) revealed different patterns of network activity and connectivity across the different social contexts (i.e., audience × intrusion). Overall, these results suggest that socially driven plasticity in the expression of territorial behavior is accommodated in the central nervous system by rapid changes in functional connectivity between nodes of relevant networks (SDMN) rather than by localized changes of activity in specific brain nuclei.

  17. Géographie Volontaire and the Territorial Logic of Architecture

    Directory of Open Access Journals (Sweden)

    Kenny Cupers

    2016-03-01

    Full Text Available This article explores the architectural and intellectual history of 'géographie volontaire', a series of experiments in inserting design volition into the study of territory. From the 1940s until the 1970s, an important group of geographers, engineers, state administrators, urban planners, and architects in France used the novel term 'géographie volontaire', or ‘volitional geography,’ to convey their ambitions for a comprehensive organization of space, from the modernization of housing and industry to the shaping of the national territory at large. It was therefore less a subdiscipline of geography than a particular logic for intervention, originating in wartime national planning and carried by the ambitions of postwar reconstruction and development. Focusing on the relationship between knowledge and design, the article reveals how 'géographie volontaire' circulated in the institutions of government and the hallways of academia and how it shaped state-led architecture and planning projects. Corresponding to postwar revisions of international modernism, 'géographie volontaire' extended the conventional scales of architecture and urbanism to the territorial. Yet more than just a change in scale, it implied both a particular political economy and a particular organization of knowledge. Shaped by the intersection of architectural and geographical knowledge, territory became a central logic for the state-led management of postwar capitalism.

    2013-12-01

    The costs of reproduction are an important constraint that shapes the evolution of life histories, yet our understanding of the proximate mechanism(s) leading to such life-history trade-offs is not well understood. Oxidative stress is a strong candidate measure thought to mediate the costs of reproduction, yet empirical evidence supporting that increased reproductive investment leads to oxidative stress is equivocal. We investigated whether territory quality and offspring provisioning increase oxidative stress in male snow buntings (Plectrophenax nivalis) using a repeated sampling design. We show that arrival oxidative stress is not a constraint on territory quality or the number of offspring fledged. Nevertheless, owners of higher-quality territories experienced an oxidative cost, with this cost increasing more rapidly in younger males. Males that provisioned offspring at a high rate also experienced increased oxidative stress. Together, these findings support the potential role of oxidative stress in mediating life-history trade-offs. Future work should consider that reproductive workload is not limited to offspring care, and other activities - including territory defence - may contribute significantly to the costs of reproduction. © 2013 The Authors.

    The urban Federal District (Distrito Federal – DF), like most Brazilian metropolitan spaces has shown similar problems, differentiating in degree and intensity of its spatial processes. One on the most relevant issues happens due to the quick paced and uncontrolled urban growth, a spatial fact that causes environmental, social, economic, institutional, and political damage, and mainly, compromises the territorial planning process.

    2016-01-01

    Full Text Available We propose an analysis of the socio-economic development processes at work in territories at the scale of French communes from 1806 to 2010. This is an extremely fine scale for such analysis, given that there are 36,000 communes in mainland France. The diachronic dimension, spanning two centuries, makes it possible to consider the temporal depth of territorial development. But the primary interest is not so much demographics as the socio-economic dimension of these variations over two centuries. We have analysed demographic changes as the expression of the socio-economic processes that shaped French territory over two centuries. Dynamic mapping of long-term population shifts reflects the industrial expansion of certain territories, decline due to the end of traditional farming practices, the shock produced by two world wars, the Fordist period and the post-war boom; the subsequent impact of an increasingly globalized, metropolitan economy then becomes apparent. We thus identify, map and analyse several historico-socio-economic phases.

    Full Text Available A rational development of industrial territories and regions implies the improvement of their cooperation in economic sector of the country, perfecting the territorial structure of husbandry, rational exploration of natural resources, usage of promising technologies, mobilization of investment etc. Along with this, the improvement of the existing and formation of a new industrial manufacture structure should be implemented with consideration of key market aspects, connected with competitiveness and innovations. Thus, an important condition of industrial structure development is the formation of innovative landscape representing the entirety of innovative territorial subjects that use innovative technologies, management tools for creation the product. In narrow sense, innovative landscape can be understood as an integrative entirety of parameters including socio-economic conditions, state administrative body, innovative economic subjects, existence of innovative infrastructure and cluster interactions etc. A methodic approach to comparative estimation of industrial regions innovative landscape parameters considered in the article lets identify its state and structural characteristics with the purpose of making more reasonable decisions on productive forces location and o n the increase of innovativeness level of industrial territories and regions.

  17. The Role of Geographical Landscape Studies for Sustainable Territorial Planning

    2017-11-01

    Full Text Available One of the primary objectives of physical geography is to determine how natural phenomena produce specific territorial patterns. Therefore, physical geography offers substantial scientific input into territorial planning for sustainability. A key area where physical geography can contribute to land management is in the delimitation of landscape units. Such units are fundamental to formal socio-economic zoning and management in territorial planning. However, numerous methodologies—based on widely varying criteria—exist to delineate and map landscapes. We have selected five consolidated methodologies with current applications for mapping the landscape to analyse the different role of physical geography in each: (1 geomorphological landscape maps based on landforms; (2 geosystemic landscape maps; (3 Landscape Character Assessment; (4 landscape studies based on visual landscape units; (5 landscape image-pair test. We maintain that none of these methodologies are universally applicable, but that each contributes important insights into landscape analysis for land management within particular biogeophysical and social contexts. This work is intended to demonstrate that physical geography is ubiquitous in contemporary landscape studies intended to facilitate sustainable territorial planning, but that the role it plays varies substantially with the criteria prioritized.

  19. The Political and Territorial Development of Nations without States

    Directory of Open Access Journals (Sweden)

    Jernej Zupančič

    2010-12-01

    Full Text Available This paper analyzes the issue of nations without states in contemporary Europe between the Atlantic and the Urals. The political map of the continent comprises forty-seven countries, most of which are nation-states. However, the cultural mosaic of Europe is far more complex; there are around fifty ethnic groups (in addition to historical, territorial, or indigenous ethnic minorities and an enormous number of immigrant ethnic communities lacking a state-based organization. Together, these people add up to 78 million, or almost 15% of the European population. Twenty-seven groups can be considered nations without states; they are culturally and ethnically based and have various forms of territorial integrity and political organization. However, they did not create a state organization, despite many attempts by some through history. Without a state organization, those communities have poorer opportunities to protect their folk culture and to reproduce various elements of ethnic identity. This is why they seek territorial autonomy or independent statehood through nationalist movements. In many cases, these ambitions are encompassed in regional movements. These movements have been popular in Europe, particularly because the idea of a “Europe of regions” as part of the European Union has had broad political support and acceptance. However, it has not actually succeeded. The EU and Europe as a whole are still a Europe of (nation-states. In general, regional movements have been successful and through this some nations without states have attained part of their political ambitions in the form of territorial autonomy. The regionalization of former centralist states (e.g., Spain and the United Kingdom increased the chances of ethnic survival for the Catalans, Basques, Scots, and Welsh. On the other hand, the regionalization of nations without states represented territorial division, a kind of “divide and rule” strategy serving to reduce their

    Full Text Available The article suggests a necessary link between urban planning and territorial organization, in order to, through the synergistic relationship between planning tools and their application to planning, implementing a policy of urban and regional management. By linking the development plan for territorial development plans and categories of land use, this methodology helps to streamline operations at multiple scales. The establishment of this network of instruments and shapes the actions of government action against the rapid and intense increase of only economic forces that shape the territory today, suggesting that it is possible to regulate the action of the housing market through planned interventions, valuing the regional balance, social and environmental - ethical by definition. It is suggested that the possible effects predatory natural and built environment can be reversed or prevented by an action articulating these planning instruments are linked to the development and implementation of plans (and projects at multiple scales, approaching from the regional to the local and metropolitan, from regional policies to sectors, that are incidents in the municipal territory.

  1. Territory occupancy and parental quality as proxies for spatial prioritization of conservation areas.

    Full Text Available In order to maximize their fitness, individuals aim at choosing territories offering the most appropriate combination of resources. As population size fluctuates in time, the frequency of breeding territory occupancy reflects territory quality. We investigated the relationships between the frequency of territory occupancy (2002-2009 vs. habitat characteristics, prey abundance, reproductive success and parental traits in hoopoes Upupa epops L., with the objective to define proxies for the delineation of conservation priority areas. We predicted that the distribution of phenotypes is despotic and sought for phenotypic characteristics expressing dominance. Our findings support the hypothesis of a despotic distribution. Territory selection was non-random: frequently occupied territories were settled earlier in the season and yielded higher annual reproductive success, but the frequency of territory occupancy could not be related to any habitat characteristics. Males found in frequently occupied territories showed traits expressing dominance (i.e. larger body size and mass, and older age. In contrast, morphological traits of females were not related to the frequency of territory occupancy, suggesting that territory selection and maintenance were essentially a male's task. Settlement time in spring, reproductive success achieved in a given territory, as well as phenotypic traits and age of male territory holders reflected territory quality, providing good proxies for assessing priority areas for conservation management.

  3. Penile vibratory stimulation yields increased spermatozoa and accessory gland production compared with rectal electroejaculation in a neurologically intact primate (Saimiri boliviensis).

    Assisted reproductive techniques require an efficient semen collection procedure in cases of ejaculatory dysfunction. Anejaculation may be of psychogenic or neurogenic origin but can be overcome with stimulatory techniques. Penile vibratory stimulation (PVS) therapy for anejaculation has recently emerged as an alternative to rectal probe electroejaculation (RPE) and more invasive testicular procedures. Comparison of the stimulatory procedures in neurologically intact subjects is not ethically possible due to the discomfort involved with electroejaculation, and comparison in spinal cord injured men may be compromised due to the intricate effects of chronic denervation on semen quality. We have previously shown the efficacy of PVS in a non-human primate, the squirrel monkey. A cross-over study design comparing semen collected by PVS and RPE was employed during the breeding season in which 15 donor males were divided into two groups. One group received PVS and the other RPE, then, three days later, treatments were reversed. Twelve of 15 animals responded to PVS (80%), all with spermatozoa in the ejaculate. Mean volume (436 +/- 90 microl), motility (80.6 +/- 4.3%), and total spermatozoa (32.8 +/- 10.2 x 10(6)) were significantly higher than in the semen after RPE. RPE resulted in ejaculation in all 15 animals with a semen volume of 205 +/- 25 microl, but fewer samples contained spermatozoa (9/15) resulting in a low total count (0.5 +/- 0.3 x 10(6)). The motility was reduced in those samples with spermatozoa (n = 9; 44.1 +/- 11.4%). Additionally, accessory gland activity was measured via the seminal vesicle and prostrate markers, fructose and citric acid, respectively. The PVS specimens had significantly more fructose (2.9 +/- 0.7 mg/ejaculate) and citric acid (0.46 +/- 0.14 mg/ejaculate) compared to RPE collected specimens (1.2 +/- 0.3 mg/ejaculate and 0.24 +/- 0.04 mg/ejaculate, respectively). In conclusion, PVS produces a much greater sperm yield and increased

  4. Evolution of foraging behaviour: Deep intra-generic genetic divergence between territorial and non-territorial southern African patellid limpets.

    Southern Africa is a biodiversity hotspot of patellid limpets, with three genera (Helcion, Cymbula and Scutellastra) identified and described in the region. Scutellastra is the most diverse and most frequently studied of these and, along with Cymbula, includes species with territorial and non-territorial foraging behaviours. We used three mitochondrial markers (12S rRNA, 16S rRNA and COI) and one nuclear marker (ATPSβ intron) to assess evolutionary relationships among species of Cymbula and Scutellastra with these two foraging behaviours and to identify which foraging mode is the more ancient. Maximum Likelihood and Bayesian Inference phylogenetic analyses revealed that the species sharing a foraging type are monophyletic in both genera. Territoriality is a derived character, as the clades with this foraging type are nested within a tree that otherwise comprises non-territorial taxa. These include Helcion, which was recovered as sister to the Cymbula/Scutellastra clade, and the next basal genus, Patella, which is ancestral to all southern African patellogastropods. Deep genetic divergence between the two foraging traits reflects strong adaptive effects of resource partitioning in the evolution of southern African patellid limpets. Copyright © 2017 Elsevier Inc.

    Full Text Available It is now generally accepted that chromosomes in the cell nucleus are organized in distinct domains, first called chromosome territories in 1909 by the great cytologist Theodor Boveri. Yet, even today chromosomes have remained enigmatic individuals, whose structures, arrangements and functions in cycling and post-mitotic cells still need to be explored in full detail. Whereas numerous recent reviews describe present evidence for a dynamic architecture of chromosome territories and discuss the potential significance within the functional compartmentalization of the nucleus, a comprehensive historical account of this important concept of nuclear organization was lacking so far. Here, we describe the early rise of chromosome territories within the context of the discovery of chromosomes and their fundamental role in heredity, covering a period from the 1870th to the early 20th century (part I, this volume. In part II (next volume we review the abandonment of the chromosome territory concept during the 1950th to 1980th and the compelling evidence, which led to its resurrection during the 1970th to 1980th.

    Acute infarction of the cervical segment of the spinal cord is extremely uncommon. Patients may present with signs and symptoms mimicking that of acute myelitis. On imaging, both conditions may present as a hyperintense area on T-2 weighted MRI. History of sudden onset is essential in establishing the diagnosis. We report a case of cervical spinal cord infarction in a 40-year-old man who was diagnosed with acute transverse myelitis, and was treated with high dose intravenous corticosteroids followed by 5 sessions of plasma exchange. An MRI of the spine revealed abnormal high T2 signal intensity extending from the C2 to C7 level involving the anterior two-thirds of the cord with more central involvement. The findings were consistent with anterior spinal artery territory cervical cord infarction.

  14. Cost of territorial maintenance by Parodon nasus (Osteichthyes: Parodontidae in a Neotropical stream

    Directory of Open Access Journals (Sweden)

    Samuel Elias Silva

    Full Text Available The combined demand over a certain resource may exceed its immediate supply, which can then lead to competition between individuals. This competition may result in territorial behavior. In this study we determine the density and spatial distribution, describe the interactions arising from territorial behavior and evaluate the costs of keeping the territories defended by adults of Parodon nasus. The study was conducted in Camarinha Stream located in the Serra das Araras Ecological Station, Porto Estrela, State of Mato Grosso, Brazil. The density was constant throughout the length of the stream, with a mean (± standard deviation of 1.01 ind./m² (± 0.14. Our results show that the spatial distribution of individuals in the area ranged between uniform and random. The territories were defended more often against intraspecific than interspecific intruders. The time that the owners of the territories devoted to defending them was not influenced by the size of the territories. However, owners of larger territories spent more time foraging than owners of smaller territories. As a result, owners of larger territories had less time to rest than owners of smaller territories. The results of this study show behavioral patterns relevant to understanding the relationship between size and territorial maintenance cost of P. nasus and other species of fish with territorial behavior.

    2017-07-01

    Full Text Available This article examines some of the problems presented in the area of the Deseado Massif, in the north-centre of the province of Santa Cruz, Argentina's southern Patagonia, a space in which the metalliferous mega-mining develops, almost exclusively, as the only possible activity. In this context, we will analyze the disputes that untie "in and for" the territory due to this activity, in a context where the multiplicity of people involved in this space make the conflicts more complex. In this scenario, the concept of territory proposed by Bernardo Mançano Fernándes, supported by a critical perspective, allows us to disrupt the plot of the conflict, under a qualitative methodology based on secondary sources. Regarding the results, this article describes the operation of the rentier mentality, the violence and the trap of abundance in regions with extractive vocation.

    Melioidosis is a tropical disease of high mortality caused by the environmental bacterium, Burkholderia pseudomallei. We have collected clinical isolates from the highly endemic Northern Territory of Australia routinely since 1989, and animal and environmental B. pseudomallei isolates since 1991. Here we provide a complete record of all B. pseudomallei multilocus sequence types (STs) found in the Northern Territory to date, and distribution maps of the eight most common environmental STs. We observed surprisingly restricted geographic distributions of STs, which is contrary to previous reports suggesting widespread environmental dissemination of this bacterium. Our data suggest that B. pseudomallei from soil and water does not frequently disperse long distances following severe weather events or by migration of infected animals. © The American Society of Tropical Medicine and Hygiene.

  18. The Guayaquil region: Territorial development and social inclusion

    2013-10-01

    Full Text Available The article looks at the process of social and economic development in the Guayaquil river basin based on a model of agro exports commodity chains. The territory or region is analyzed by looking at social and economic dynamics as opposed to political administrative divisions, which covers a wider area that extends to the provinces of Los Ríos, Manabí and Santa Elena. This article is part of a more extensive research project on Guayaquil and the region, that looks at rural urban linkages and how the common feature of the regional economy is the dependence of the rural periphery on Guayaquil either for industrial or export processing. By focusing on the main agro-commodity chains that shape the territory, including coffee, cocoa and banana for export, as well as rice and corn for the internal market, one can see how regional development was built on the basis of the rural economy.

  19. Where's the smartness of learning in smart territories ?

    2014-11-01

    Full Text Available In the future smarter territories are expected to induce transformations of many aspects of the learning processes, but how their smartness is and will be related to that of the learning ecosystems ? In this paper, by means of Principal Component Analysis, we critically analyse methods presently used to benchmark and produce University rankings, by focusing on the case study of the Italian Universities. The outcomes of such analysis allow us to demonstrate the existence of a strong correlation between smart cities' and universities' rankings, i.e. between learning ecosystems and their territories of reference. Present benchmarking approaches, however, need to take in more consideration people feelings and expectations. Accordingly we suggest an innovative point of view on the benchmarking of learning ecosystems based, also, on the so called flow.

    Full Text Available “Economies of agglomeration” have acted as catalysts of the progress and modernisation of many nations in the Global South but have also contributed to unbalancing the territory, widening the gap between urban and rural populations and the accumulation of high environmental and social deficits. In contrast to the BRICS (Brazil, Russia, India, China and South Africa, the economies that make up the MINTs (Mexico, Indonesia, Nigeria and Turkey have better territorial integration of their urban systems, with intermediate cities that act as “economies of intermediation” with the rural hinterlands, and which could contribute to achieving the United Nations’ 2030 Agenda for Sustainable Development Goals. The United Nations Habitat iii of October 2016 placed intermediary cities at the heart of the New Urban Agenda. The aim is to promote national urban policies in many of the economies of the Global South, allowing them to strengthen their role as the main instrument of economic integration and regional cohesion.

  1. From territoriality to altruism in interprofessional collaboration and leadership.

    Science.gov (United States)

    Axelsson, Susanna Bihari; Axelsson, Runo

    2009-07-01

    Interprofessional collaboration has become more and more necessary in health and social care, mainly because of the increasing specialization of services and the increasing professionalization of different occupational groups. Most interprofessional collaboration is at the same time also interorganizational and it is taking place within a complicated structure, where collaborative teamwork is combined with hierarchical co-ordination and control in a sort of matrix organization. Based on the literature on organization, leadership and collaboration, this paper discusses territorial behaviour among professional groups and agencies as a difficult barrier to interprofessional collaboration. In order to overcome that barrier, the concept of altruism is explored as an alternative to territoriality. Professional altruism as well as altruistic leadership is discussed as a condition and a possibility for interprofessional collaboration. The discussion is illustrated with empirical data from a case study of collaboration in vocational rehabilitation.

    Full Text Available The article is devoted to studying institutional basis of organizing public governance for territory development by means of e-Governance system. In particular, there were presented the bases for creating such a system, its components, stages of implementation and were developed institutional governance mechanisms by means of basic “e-services”. Assuming that public authorities represent a certain “black box” which provides services according to the “one stop” principle, a citizen has a possibility to obtain them in accordance with his “life episode”. Thus, one governing system would be characterized by the principles of responsibility and accountability to the locals and by the involvement in meeting local territories needs.

    Acute lower respiratory infections (ALRIs) are the most common reason for hospitalisation of young children in the Northern Territory of Australia. International studies have linked vitamin D deficiency with increased risk of ALRI in paediatric populations, but this has not been explored in tropical regions such as the Top End of the Northern Territory. The aim of this study is to determine the prevalence of vitamin D insufficiency among children hospitalised with ALRI in the Northern Territory. Vitamin D serum metabolite (25OHD3) levels were retrospectively measured using liquid chromatography-mass spectrometry in 74 children (64% male; 57% Indigenous) aged less than 3 years admitted to Royal Darwin Hospital in the Northern Territory of Australia between May 2008 and May 2010. There were 44 (59%) ALRI-classified hospitalisations and 30 (41%) non-ALRI-classified hospitalisations. The most common ALRI diagnoses were bronchiolitis (n = 22, 30%) and pneumonia (n = 21, 28%), whereas the most common non-ALRI diagnosis was gastroenteritis (n = 20, 27%). Overall, 24/74 (32%) children had 25OHD3 levels <75 nmol/L (insufficiency). For children hospitalised with ALRI, 23% (10/44) had vitamin D insufficiency compared with 47% (14/30) among children hospitalised for other reasons (odds ratio 0.34, 95% confidence interval 0.11-1.03; P = 0.043). Twelve of the 20 (60%) children hospitalised for gastroenteritis had vitamin D insufficiency. Vitamin D insufficiency was observed in almost one-third of these hospitalised children. Children hospitalised with an ALRI were less likely to have vitamin D insufficiency compared with children hospitalised for other conditions (predominantly gastroenteritis). © 2014 The Authors.

  11. Rural electrification: Waste biomass Russian northern territories. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Adamian, S. [ECOTRADE, Inc., Glendale, CA (United States)

    1998-02-01

    The primary objective of this pre-feasibility evaluation is to examine the economic and technical feasibility of replacing distillate fuel with local waste biomass in the village of Verkhni-Ozerski, Arkhangelsk Region, Russia. This village is evaluated as a pilot location representing the off-grid villages in the Russian Northern Territories. The U.S. Department of Energy (DOE) has agreed to provide technical assistance to the Ministry of Fuel and Energy (MFE). MFE has identified the Northern Territories as a priority area requiring NREL`s assistance. The program initially affects about 900 off-grid villages. Biomass and wind energy, and to a lesser extent small hydro (depending on resource availability) are expected to play the dominant role in the program, Geothermal energy may also have a role in the Russian Far East. The Arkhangelsk, Kariela, and Krasnoyarsk Regions, all in the Russian Northern Territories, have abundant forest resources and forest products industries, making them strong candidates for implementation of small-scale waste biomass-to-energy projects. The 900 or so villages included in the renewable energy program span nine administrative regions and autonomous republics. The regional authorities in the Northern Territories proposed these villages to MFE for consideration in the renewable energy program according to the following selection criteria: (a) Remote off-grid location, (b) high cost of transporting fuel, old age of existing power generation equipment, and (d) preliminary determination as to availability of alternative energy resources. Inclusion of indigenous minorities in the program was also heavily emphasized. The prefeasibility study demonstrates that the project merits continuation and a full feasibility analysis. The demonstrated rate of return and net positive cash flow, the willingness of Onegales and local/regional authorities to cooperate, and the immense social benefits are all good reasons to continue the project.

    2009-01-01

    Secondary analysis of the trends and correlates of consanguinity in the Palestinian Territories was conducted using data from two separate surveys in 1995 and 2004. The analysis was conducted on ever-married women aged 15-54 who were asked about their relation to their husband in both surveys. A total of 16,197 women in 1995 and 4971 women in 2004 were successfully interviewed. Consanguinity was found to be widely practised in the Palestinian Territories with rates of total consanguinity reaching 45% of all marriages in 2004. Analysis was conducted with the data from the two surveys combined and this indicated that consanguinity was significantly decreasing with time after controlling for other variables. Age of the women, their age at marriage, region and locality type they lived in and their standard of living were all found to be significant predictors of consanguinity. The education level of the women was not found to be significant. After controlling for the survey year, women's labour force status was also found to be a non-significant predictor of consanguinity. Although consanguinity was found to be significantly decreasing slowly with time after controlling for other variables, the future trends of consanguinity are not known due to the unstable political situation in the territories, which could have a direct effect on marriage patterns.

    1995-01-01

    Spoken language disorders are rarely mentioned in superficial infarction of the posterior cerebral (PCA) territory. Two clinical types have been reported: transcortical sensory and amnesic aphasia. Between 1979 and 1990, we studied retrospectively 76 patients suffering from an occipitotemporal infarction located in the superficial territory of the posterior cerebral artery, all well documented by CT. Aphasia was one of the first and prominent signs in 18 cases. Middle cerebral artery concomitant infarction could have been the cause of language impairment in 10. In 8 patients aphasia was only explained by a PCA territory infarct. Three patients showed features of transcortical sensory aphasia. CT localization showed internal lobe and thalamic involvement of the dominant hemisphere. Five patients exhibited word finding impairment with various degrees of amnestic syndrome. The dominant internal temporal lobe was always affected. Dominant thalamus involvement was found in one case only. Some correlations between clinical features and anatomical support (vascular supply and anatomical structure) might be suggested in our 8 cases of aphasic disorders due to PCA infarcts. They are discussed and compared with data in the literature.

    Barbaro, Alethea B. T.; Chayes, Lincoln; D'Orsogna, Maria R.

    2013-01-01

    We study the well-known sociological phenomenon of gang aggregation and territory formation through an interacting agent system defined on a lattice. We introduce a two-gang Hamiltonian model where agents have red or blue affiliation but are otherwise indistinguishable. In this model, all interactions are indirect and occur only via graffiti markings, on-site as well as on nearest neighbor locations. We also allow for gang proliferation and graffiti suppression. Within the context of this model, we show that gang clustering and territory formation may arise under specific parameter choices and that a phase transition may occur between well-mixed, possibly dilute configurations and well separated, clustered ones. Using methods from statistical mechanics, we study the phase transition between these two qualitatively different scenarios. In the mean-fields rendition of this model, we identify parameter regimes where the transition is first or second order. In all cases, we have found that the transitions are a consequence solely of the gang to graffiti couplings, implying that direct gang to gang interactions are not strictly necessary for gang territory formation; in particular, graffiti may be the sole driving force behind gang clustering. We further discuss possible sociological-as well as ecological-ramifications of our results.

    Full Text Available BACKGROUND: There are no recent data on the prevalence and causes of blindness in the Occupied Palestinian Territories. The aim of our study was to estimate the prevalence and causes of blindness and visual impairment in the population aged 50 years and above in the Occupied Palestinian Territories using the Rapid Assessment of Avoidable Blindness (RAAB survey method. METHODS AND FINDINGS: Clusters of 40 people who were 50 years and above were selected with probability proportionate to size using a multistage cluster random sampling method. Participants received a comprehensive ophthalmic examination in their homes, including visual acuity testing by one of three experienced ophthalmologists. The principal cause for visual loss was determined by an experienced ophthalmologist using portable diagnostic instruments. Information about previous cataract surgery, satisfaction with surgery and barriers to cataract surgery were collected. The prevalence of self-reported diabetes was also determined. The prevalence of bilateral blindness (VAor=3/60 and or=6/60 and or=6/18, 23.2% had a borderline outcome (VAor=6/60 and 22.3% had a poor outcome (VAor=50 year age group was 26.4% (95% CI: 24.9-27.9. CONCLUSIONS: The prevalence of blindness suggests that significant numbers of people in the Occupied Palestinian Territories exist who do not access eye care - predominantly women and those residing in Gaza. Programmes need to focus on maximizing the use of current services by these excluded groups.

    Atrial fibrillation (AF) is a cause of ischemic stroke and is associated with recurrence and with acute multi-vessel territory non lacunar stroke. Many cryptogenic strokes could be secondary to undiagnosed paroxystic AF. As left atrium (LA) dilatation is a risk factor of AF, we sought to determine if moderate or severe LA dilatation was associated with multiple vascular territory infarcts on magnetic resonance imaging (MRI) in patients with acute ischemic stroke without known AF. Normal LA diameter values are ≤4.0 cm for men and ≤3.8 for women. Patients who presented at our center between 2006 and 2011 with a diagnosis of acute ischemic stroke (AIS) or transient ischemick attack (TIA) who had a transthoracic echocardiography and a brain MRI were included. Patients with known or de novo AF diagnosed within 3 months of the event were excluded. The main outcome was the presence of acute multi-vessel territory infarct(s) on MRI. 356 patients were included. The mean LA diameter was 37 mm in the control group (normal or mildly dilated LA) and 49 mm in those with moderately to severely enlarged LA (pterritory infarcts on MRI in patients with AIS or TIA without known AF or a confirmed diagnosis of AF. Further studies are necessary to determine if this population might benefit from anticoagulation therapy.

  18. The Process Architecture of EU Territorial Cohesion Policy

    Directory of Open Access Journals (Sweden)

    Andreas Faludi

    2010-08-01

    Full Text Available When preparing the European Spatial Development Perspective (ESDP, Member States were supported by the European Commission but denied the EU a competence in the matter. Currently, the Treaty of Lisbon identifies territorial cohesion as a competence shared between the Union and the Member States. This paper is about the process architecture of territorial cohesion policy. In the past, this architecture resembled the Open Method of Coordination (OMC which the White Paper on European Governance praised, but only in areas where there was no EU competence. This reflected zero-sum thinking which may continue even under the Lisbon Treaty. After all, for as long as territorial cohesion was not a competence, voluntary cooperation as practiced in the ESDP process was pursued in this way. However, the practice of EU policies, even in areas where there is an EU competence, often exhibits features of the OMC. Surprisingly effective innovations hold the promise of rendering institutions of decision making comprehensible and democratically accountable. In the EU as a functioning polity decision making is thus at least part deliberative so that actors’ preferences are transformed by the force of the better argument. This brings into focus the socialisation of the deliberators into epistemic communities. Largely an informal process, this is reminiscent of European spatial planning having been characterised as a learning process.

As a result most of the existing natural conditions have been modified. Parts of them cover the natural forms of river beds and floodplains. Concerning to the humans safety, comfort and needs, while keeping ecosystems healthy function, different artificial structures also have been created. The process is connected to the well understanding and good quality data obtaining about the existing conditions and river flow behaviour, that are interconnected and relevant to the river discharge determination and its variations description – key issue for the entire river structures project, water extremes mitigation and maintaining a healthy state of the ecosystems. For the purpose various contact measurements and monitoring procedures are implemented. To clarify the process this material aims to present some specifics connected to the urban territories river discharge determination and the possibility for related monitoring networks creation. It is focused on the most used methods, their specifics and possible challenges for practical application. Main specifics connected to the related decision support systems creation and implementations are also presented. Main purpose is such state of the art dissemination, in help of decision makers and professionals in the area.

    Full Text Available Contrary to popular belief, the spatial aspect of political processes is  determined not only by objective factors. Space affects politics not  only directly, but also indirectly, through subjective and sometimes  distorted notions of space, formed by man. To study this subjective world, geography has its own terminology, some of which  are in dialectical connection with the concepts of «objective»  geography (territoriality vs. spatiality, absolute vs. relative space,  and some are unique for the discourse of this science (heterotopy,  spatial inversion, spatial experience, the place of memory, spatial  myth, and co-spatiality. The key to political geography is the notion of territorial and spatial identity, because they link ideas  about space with the political behavior of the individual. Recently,  the applied sphere of political geography has been actively  developing, based on the application of identity knowledge - territory branding based on place policy.

Tanto los profesores de las diferentes materias de Derecho de nuestra Facultad como las asociaciones profesionales y otros grupos e juristas de nuestro medio, formularon reservas de diverso calibre sobre el texto de la ley que van desde sus aspectos adjetivos como la terminología y redacción hasta cuestiones sustanciales como lo que ella dice sobre el régimen de la propiedad territorial y otras cuestiones vinculadas.Desde el discurso político vimos lanzar opiniones iracundas y alarmistas sobre las modificaciones que la ley estaría haciendo al régimen de la propiedad privada, sobre su supuesta inconstitucionalidad.Nosotros nos vamos a referir a la ley a sus antecedentes y de las críticas que se le hacían, en la parte que toca a nuestra materia, esto es en lo relativo al régimen de la propiedad y debemos decir, a vía de adelanto, que no vemos en ella nada que afecte el derecho de propiedad consagrado por la Constitución de la República, ni los principios generales que regulan la propiedad territorial conforme al Código Civil, conforme a la vieja ley de Centros Poblados, sus modificativas ni demás normas sobre la materia.

  2. The collective action problem in primate territory economics.

    Group-living animals often do not maintain territories, but instead have highly overlapping ranges, even though in principle these are economically defendable. We investigate whether this absence of range defence reflects a collective action problem, since a territory can be considered a public good. In a comparative analysis comprising 135 primate species, we find a positive association between range overlap and group size, controlling for economic defendability and phylogenetic non-independence. We subsequently demonstrate that groups with multiple adults of both sexes suffer levels of range overlap twice as high as groups with only a single adult representative of either sex, consistent with the presence of a collective action problem. Finally, we reveal that this collective action problem can be overcome through philopatry of the larger sex. These results suggest that a social complication of group living is a stronger determinant of between-group relations among social animals than ecological factors, but also that collective defence is still achieved where the dominant sex is philopatric and effective defence is critical to reproductive success and survival. In addition, our findings support the idea that human-like warfare, defined as escalated collective territorial conflict, has an evolutionary basis reflected by cases of convergent evolution among non-human primates.

  3. A simple iterative independent component analysis algorithm for vibration source signal identification of complex structures

    Full Text Available Independent Component Analysis (ICA, one of the blind source separation methods, can be applied for extracting unknown source signals only from received signals. This is accomplished by finding statistical independence of signal mixtures and has been successfully applied to myriad fields such as medical science, image processing, and numerous others. Nevertheless, there are inherent problems that have been reported when using this technique: insta- bility and invalid ordering of separated signals, particularly when using a conventional ICA technique in vibratory source signal identification of complex structures. In this study, a simple iterative algorithm of the conventional ICA has been proposed to mitigate these problems. The proposed method to extract more stable source signals having valid order includes an iterative and reordering process of extracted mixing matrix to reconstruct finally converged source signals, referring to the magnitudes of correlation coefficients between the intermediately separated signals and the signals measured on or nearby sources. In order to review the problems of the conventional ICA technique and to vali- date the proposed method, numerical analyses have been carried out for a virtual response model and a 30 m class submarine model. Moreover, in order to investigate applicability of the proposed method to real problem of complex structure, an experiment has been carried out for a scaled submarine mockup. The results show that the proposed method could resolve the inherent problems of a conventional ICA technique.

    The locations of 22 territorial gray wolves (Canis lupus) killed by conspecifics in northeastern Minnesota were analyzed in a study involving radio-telemetry from 1968 through 1992. Twenty-three percent of the wolves were killed precisely on the borders of their estimated territories; 41%, within 1.0 km (16% of the radius of their mean-estimated territory) inside or outside the estimated edge; 91%, within 3.2 km inside or outside (50% of the radius of their mean-estimated territory) of the estimated edge. This appears to be the first report of intraspecific mortality of mammals along territorial boundaries.

On the basis of the illuminated materials were obtained the following conclusions: Signifi cant interest in the Arctic show today, not only the fi ve countries (Russia, USA, Canada, Norway, Denmark, who own Arctic territories, but also polar state (Iceland, Sweden, Finland, the European Union and Asia. As a consequence of that, it is expected that in the XXI century the Arctic region will be the focus of attention as an official Arctic 45, and a number of states whose territory is quite removed from it; For Russia, given the current, acute political conditions (sanctions, confrontation with the West, Ukrainian crisis and war in the Middle East development of Arctic territories, some moved away, moved on tomorrow and the day after tomorrow on the agenda. This approach is fundamentally fl awed and fraught with a number of threats, because other countries do not decrease, but only increase their interest in this issue; Territorial opposition to all those involved in the topic of causing instability in the Arctic region, but does not represent a real threat for the emergence of large-scale conflict. Therefore, making the choice between the hard pressure of national interests and the interests of harmonization of the Arctic states, Russia must be based on international cooperationand mutual consideration of interests in the development of its Arctic strategy; Considering the cooperation of the countries of the Arctic Council and their cooperation in the framework of a global economic forum G8, there are prerequisites for the decision of the Arctic confl ict through negotiation and compromise.

    2012-07-01

    Full Text Available The paper focuses on a neglected group of territorial politics: the dominant non-territorially defined political parties, mainly catch-all parties of Christian Democratic or Social Democratic origin. In contrast to regionalist parties, they do not have incentives for territorial reforms, yet they are engaged in them. Despite a state of mutual neglect between the literature on territorial politics and the catch-all party branch of party theory, we argue that the catch-all party model does help understand territorial party politics in two steps. Territorial reforms as practical tests put catch-all parties under tremendous stress, since particularistic regionalist interests may threaten the catch-all party formula of competitiveness with its symmetry of interest group integration. According to the degree of the threat, catch-all parties take countermeasures in territorial reforms, restoring the respective conditions again. To test this hypothesis and identify this mechanism of ‘threat and response’, we scan territorial reforms in Germany, Austria, Great Britain and Italy.

  8. Genes located in a chromosomal inversion are correlated with territorial song in white-throated sparrows.

    The genome of the white-throated sparrow (Zonotrichia albicollis) contains an inversion polymorphism on chromosome 2 that is linked to predictable variation in a suite of phenotypic traits including plumage color, aggression and parental behavior. Differences in gene expression between the two color morphs, which represent the two common inversion genotypes (ZAL2/ZAL2 and ZAL2/ZAL2(m) ), may therefore advance our understanding of the molecular underpinnings of these phenotypes. To identify genes that are differentially expressed between the two morphs and correlated with behavior, we quantified gene expression and terrirorial aggression, including song, in a population of free-living white-throated sparrows. We analyzed gene expression in two brain regions, the medial amygdala (MeA) and hypothalamus. Both regions are part of a 'social behavior network', which is rich in steroid hormone receptors and previously linked with territorial behavior. Using weighted gene co-expression network analyses, we identified modules of genes that were correlated with both morph and singing behavior. The majority of these genes were located within the inversion, showing the profound effect of the inversion on the expression of genes captured by the rearrangement. These modules were enriched with genes related to retinoic acid signaling and basic cellular functioning. In the MeA, the most prominent pathways were those related to steroid hormone receptor activity. Within these pathways, the only gene encoding such a receptor was ESR1 (estrogen receptor 1), a gene previously shown to predict song rate in this species. The set of candidate genes we identified may mediate the effects of a chromosomal inversion on territorial behavior. © 2015 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

    2009-09-01

    We describe Irukandji syndrome (a painful hypercatecholaminergic condition caused by jellyfish envenoming) in Australia's Northern Territory. We collected prospectively a standardized data set on patients presenting to health facilities in the Northern Territory. Additional cases were identified retrospectively. Data collected included demographic, geographic, seasonal, and environmental features, as well as sting details, clinical manifestations, investigations, management, and outcomes. From 1990 to 2007, Irukandji syndrome affected 87 people. Age ranged from 1 to 51 years (64% male victims; 41% children [63% indigenous]). Activities associated with stings included snorkeling or scuba diving (35%) and swimming (29%). Stings commonly occurred in water greater than 2 m deep (63%), with fine weather (73%) and still or light breeze (70%). Seasonal variation was bimodal; peaks in May and October corresponded to prevailing offshore winds in the Darwin and Gove areas, respectively. Pain was severe (65%), with rapid onset (<30 minutes in 79%). Sting lesions (visible in 63%) were mild, and nematocysts (detected in 7 cases) had variable morphology. Systemic features were common, including hypertension and ECG abnormalities. Severe complications included troponin-level increases (2 cases) and cardiomyopathy with ventricular tachycardia (1 case), but no fatalities. Management included vinegar as first aid (66%), parenteral opioids (70%) (range 2 to 82.5 mg morphine equivalents in adults), and magnesium sulfate (3 cases). Hospital admission (49%) and aeromedical retrieval (16%) were commonplace. Irukandji syndrome in the Northern Territory was clinically consistent with previous studies but had distinct seasonal, geographic, and environmental features. Indigenous children in remote coastal communities are at risk, and there is room for improvement in prevention and management.

    Full Text Available This article presents the results of the research of the application on a state level of the program management approach to the territorial development of small business. Studying the main mechanism of the state policy implementation in the sphere of small business on a regional level, the authors have revealed the necessity to take into account the territorial specificity while the government programs of small business development are being formed. The analysis of the national practice of utilizing the program management mechanism in the regional system of the government support of small entrepreneurship was conducted on the example of Omsk region. The results of the analysis have shown the inefficiency of the current support system for small business and have determined the need to create an integrated model of territorial programming, which would not only contribute to the qualitative development of small business, but also provide the functioning efficiency of program management mechanism. As a result, the authors have created the two-level model of the programming of the territorial development of small business, which allows to satisfy purposefully the needs of entrepreneurship taking into account the specificity of the internal and external environment of the region. The first level of the model is methodological one and it is based on the marketing approach (the concepts of place marketing and relationship marketing to the operation of the program management mechanism. The second level of the model is methodical one. It offers the combination of the flexible methods of management of programming procedure (benchmarking, foresight, crowdsourcing and outsourcing. The given model raises the efficiency of the management decisions of the state structures in the sphere of small business. Therefore, it is interesting for the government authorities, which are responsible for the regional and municipal support programs of small business, as well

    Full Text Available The end of World War I and the victory of the forces of Antante on 11 November 1918 did not result in the end of war in Londonized Albania and in the territories inhabited by Albanian people in Yugoslavia and Greece because neighbouring countries did not withdraw from Albanian territories since their desires were to extend even more to the detriment of the Albanian and were not satisfi ed only with the invasion of Kosovo by Serbia, Cameria by Greece, and Italy aspiring to keep Albania under its supervision. The European countries of Antante, such as England, France and Italy, did not support the Albanian people because they had reached an agreement during the World War 1 to conquer the countries of the triple alliance by promising Albanian territories to the neighbouring countries of Albania. The Protocol of April 1915 was devastating for Albania. The fate of Albanian people was such that European countries could not change the course of the World War 1. The intervention of USA was the one that changed the course of the World War 1, and USA even joined the war by stating that it did not recognize the agreements made during the war with regard to the territorial division. The neighboring countries of Albania had forgo$ en that in the global stage a political-military power was emerging which would lay the foundations of the new world order. Even though the war had ended, the neighboring countries of Albania were making agreements for the supervision of Albania. Italy was interested in keeping Albania under its supervision whereas Greece and Yugoslavia were interested in the division of Albania. Under these circumstances the Albanian people was facing new invasive challenges and they had to get organized both inside and outside the country for their national salvation. Albanians were organized in clubs and associations abroad, in order to help the freedom of Londonized Albania. The Albanians in Albania were fed up with long and savage invasions

    To investigate the relationship between the level of collateral circulation and perfusion territory normalisation after carotid endarterectomy (CEA). This study enrolled 22 patients with severe carotid stenosis that underwent CEA and 54 volunteers without significant carotid stenosis. All patients were scanned with ASL and t-ASL within 1 month before and 1 week after CEA. Collateral circulation was assessed on preoperative ASL images based on the presence of ATA. The postoperative flow territories were considered as back to normal if they conformed to the perfusion territory map in a healthy population. Neuropsychological tests were performed on patients before and within 7 days after surgery. ATA-based collateral score assessed on preoperative ASL was significantly higher in the flow territory normalisation group (n=11, 50 %) after CEA (P territory normalisation group [>mean differences+2SD among control (MMSE=1.35, MOCA=1.02)]. This study demonstrated that effective collateral flow in carotid stenosis patients was associated with normalisation of t-ASL perfusion territory after CEA. The perfusion territory normalisation group tends to have more cognitive improvement after CEA. • Evaluation of collaterals before CEA is helpful for avoiding ischaemia during clamping. • There was good agreement on ATA-based ASL collateral grading. • Perfusion territories in carotid stenosis patients are altered. • Patients have better collateral circulation with perfusion territory back to normal. • MMSE and MOCA test scores improved more in the territory normalisation group.

    High-quality territories are expected to provide greater fitness return for breeding individuals and, thus, are likely to have higher long-term occupation rate in comparison to low-quality territories. However, if environmental and ecological cues used for territory selection cannot reliably predict true territory quality, a mismatch between preferences and fitness may occur. We suggest that this kind of non-adaptive territory selection is more likely in species with long reproductive cycles, as a long time interval between territory establishment and young fledgling should reduce predictability of conditions during the critical stages of brood care. In this study, we investigated adaptiveness of territory selection in a migratory bird with exceptionally long parental care, the mute swan Cygnus olor, which requires over four months to complete the entire reproductive cycle from egg laying to young fledging. For this purpose, we collected information on the long-term (10-19 years) occupancy of 222 swan breeding territories and correlated it with reproductive performance (n = 1,345 breeding attempts) and body condition of breeding adults. We found that long-term occupancy positively correlated with the timing of breeding, suggesting that individuals settled earlier in the attractive, frequently occupied territories. By contrast, we found no relationship between territory occupancy and reproductive output (hatching and fledging success) or adult body condition. The results indicate that at the time of territory selection swans might not be able to reliably assess territory quality, likely due to: (1) exceptionally long period of parental care, which reduces temporal correlation between the conditions at the time of territory selection and conditions during chick rearing; and (2) unpredictability of human-related activities that had a major impact on reproductive output of swan pairs in our population.

    1. We contrast the value of four different models to predict variation in territory size as follows: resource density (the ideal free distribution), population density, group size and intruder pressure (relative resource-holding potential). In the framework of the resource dispersion hypothesis, we test the effect of resource abundance and spatial variation in resource distribution on the age/sex composition of social groups. 2. We explore these drivers of territory size and group size/composition in Ethiopian wolves Canis simensis in the Bale Mountains, Ethiopia, using fine-scale distribution maps of their major prey species based on satellite-derived vegetation maps. 3. The number of adult males is correlated with territory size, while prey density, wolf population density and intruder pressure are not associated with territory size. On average, each additional adult male increases territory size by 1.18 km(2). 4. Prey abundance increases with territory size (average biomass accumulation of 6.5 kg km(-2)), and larger territories provide greater per capita access to prime foraging habitat and prey. 5. The age/sex composition of wolf packs is more closely related to territory quality than territory size. Subordinate adult females are more likely to be present in territories with greater proportions of prime giant molerat Tachyoryctes macrocephalus habitat (i.e. >80% of Web Valley territories and >20% in Sanetti/Morebawa), and more yearlings (aged 12-23 months) occur in territories with greater overall prey biomass. 6. Wolf packs with restricted access to good foraging habitat tend to defend more exclusive territories, having a lower degree of overlap with neighbouring packs. 7. The greater per capita access to prey in large groups suggests a strong evolutionary advantage of collaborative territorial defence in this species, although the relative costs of territorial expansion vs. exclusion depend upon the spatial distribution of resources. We propose a model

  5. A mismatch between the perceived fighting signal and fighting ability reveals survival and physiological costs for bearers.

    Full Text Available Signals of fighting indicate an animal's intention to attack and so they serve to prevent costly aggressive encounters. However, according to theory, a signal that is different in design (i.e. a novel signal but that fails to inform fighting intentions will result in negative fitness consequences for the bearer. In the present study we used males of the territorial damselfly Hetaerina americana, which have a red wing spot during territory defense that has evolved as a signal of fighting ability. By producing a novel signal (covering the red spot with blue ink in territory owners, we investigated: a the behavioral responses by conspecific males; b survival cost and c three physiological mediators of impaired survival: muscular fat reserves, muscle mass and immune ability. We predicted that males with the novel signal would be attacked more often by conspecifics as the former would fail to convey fighting ability and intentions adequately. This will result in lower survival and physiological condition for the novel signal bearers. We found that, compared to control males (males whose red spot was not changed, experimental males had reduced survival, were less able to hold a territory, and had a reduced muscle mass. It seems that spot modified males were not able to effectively communicate their territory tenancy, which may explain why they lost their defended sites. Our results provide support for theoretical models that a novel signal that fails to informing fighting ability may lead to a fitness cost for bearers.

    Signals play a key role in the ecology and evolution of animal populations, influencing processes such as sexual selection and conflict resolution. In many species, sexually selected signals have a dual function: attracting mates and repelling rivals. Yet, to what extent males and females under natural conditions differentially respond to such signals remains poorly understood, due to a lack of field studies that simultaneously track both sexes. Using a novel spatial tracking system, we tested whether or not the spatial behavior of male and female great tits (Parus major) changes in relation to the vocal response of a territorial male neighbor to an intruder. We tracked the spatial behavior of male and female great tits (N = 44), 1 hr before and 1 hr after simulating territory intrusions, employing automatized Encounternet radio-tracking technology. We recorded the spatial and vocal response of the challenged males and quantified attraction and repulsion of neighboring males and females to the intrusion site. We additionally quantified the direct proximity network of the challenged male. The strength of a male's vocal response to an intruder induced sex-dependent movements in the neighborhood, via female attraction and male repulsion. Stronger vocal responders were older and in better body condition. The proximity networks of the male vocal responders, including the number of sex-dependent connections and average time spent with connections, however, did not change directly following the intrusion. The effects on neighbor movements suggest that the strength of a male's vocal response can provide relevant social information to both the males and the females in the neighborhood, resulting in both sexes adjusting their spatial behavior in contrasting ways, while the social proximity network remained stable. This study underlines the importance of "silent" eavesdroppers within communication networks for studying the dual functioning and evolution of sexually

    Population growth in cities, the need to expand the living space requires of rational use of territories within the existing boundaries of the city. The necessity of compliance with the functional zones of the city is shown on the example of a representative part of Kiev, that should be performed taking into account engineering-geological features of the territory. It is necessary to comply with the underlying zones in the underground space to ensure the bearing capacity of the soil mass. The changes in soil bases are defined as a result of changes in the stress-strain state under the construction, development of underground space, changes of soils water content as the result of soaking from the surface, formation of "perched water", raising the groundwater level. The vibration analysis of high-rise building - the main library building is made from the dynamic loads that arise during the movement of the vehicle, taking into account the work of the pile foundation as a rigid body relative to the longitudinal axis, which passes through the center of the building at the level of the cap of piles.

    Many studies have found that consanguinity poses a threat to child mortality and health and can also pose a threat to offspring survival before birth. However, there are conflicting findings with some studies having found no increased risk on offspring survival associated with consanguinity. Data from a population-based survey conducted in 2004 in the Palestinian Territories was used to assess the risk of consanguinity on offspring survival. The analysis was conducted on 4418 women aged 15-49 who were asked whether or not they had experienced a stillbirth or a spontaneous abortion. These two outcomes were combined together for the analysis of reproductive wastage. Multivariable negative binomial regression was conducted to calculate the incidence risk ratios (IRR) for each region in the Palestinian Territories separately. The strongest risk factors for reproductive wastage, after controlling for other variables, were found to be consanguinity, age and parity with age presenting the highest IRRs. Standard of living, locality type, education level, women's employment and past intrauterine device use were not found to be significant risk factors for reproductive wastage. In the West Bank only first cousin level of consanguinity was found to be significant and 'hamola' level (or from same family clan) lost its significance after adjusting for other variables. In the Gaza Strip both the first cousin and 'hamola' levels of consanguinity were significant and presented almost equal IRRs of 1.3. In conclusion, consanguinity was found to be a significant risk factor for reproductive wastage.

    Full Text Available Objectives: To evaluate the significance of the territory of Bonfim as an area of knowledge production for students of the Health Sciences Center, Federal University of Espírito Santo, in Vitória-ES, Brazil. Methods: This study conducted a survey of all the works produced by undergraduate and postgraduate students of the health area from that university who investigated the mentioned territory. The field work resulted in the cataloging of eleven studies that had been characterized in accordance with the subject, the investigated problem; the approaches of the study and the year of its production. These works were distributed in two great thematic axis: studies related to the local management of health system and studiesrelating to child and adolescent health, respectively. Results: Surprisingly, we found out that all the works consisted of studies conducted by nursing graduate students. Conclusions: The non-participation of students from other graduation courses and / or post-graduation of that university, in the generation of knowledge that take account of exploring that reality, points to the need of the university community to cross the imaginary line that separates the academy from real world.

    Full Text Available Teachers should care for the emotional stability of their students, teachers must take on the work of social workers, teachers have to answer to those problems caused by the difficult socio-economic situation facing our students... Today, phrases like these are common in discussions among teachers and non-teachers. All of them, one way or another, relate to teacher's identity, and all are trying to tell their own truth about what is like being a teacher today. Obviously, not all refer to the processes of learning or teaching learning problems. What is then the identity of a teacher? What does the word "teacher" encapsulate in its meaning in today's society? We will try to make an approach to the definition of a teacher's identity but not looking for a single, dogmatic definition, but by highlighting some landscapes that will identify this territory. Our position will be, therefore, that of a cartographer trying to peer into the world through his own observations (provided he has the ability to travel to the land he is trying to represent, or with data from narratives of those who have traveled there already, or through representations made by others before him. Certainly, like any map, our representation will not be a finished product , but an attempt to present to other man and woman signs to orientate themselves in this new territory and that they themselves will enrich with their personal contributions.

    Full Text Available The principle of decentralization is a fundamental principle for the establishment and operation of local government. It refers to the process of redistributing the authority and responsibility for certain functions from central government to local government units. In many countries, particularly in developing countries, fiscal decentralization and local governance issues are addressed as highly important to the economic development. According to Stigler (1957, fiscal decentralization brings government closer to the people and a representative government works best when it is closer to the people. Albania is still undergoing the process of decentralization in all aspects: political, economic, fiscal and administrative. Decentralization process is essential to sustainable economic growth and efficient allocation of resources to meet the needs of citizens. Albania has a fragmented system of local government with a very large number of local government units that have neither sufficient fiscal or human capacity to provide public services at a reasonable level (World Bank. However, recent administrative and territorial reform is expected to have a significant impact in many issues related to local autonomy and revenue management. This paper is focused on the progress of fiscal decentralization process in Albania, stating key issues and ongoing challenges for an improved system. The purpose of this study is to analyze the effects of recent territorial reform, identifying problems and opportunities to be addressed in the future.

    Full Text Available The aim of this paper is to ascertain the territorial dimension of the fishing economy in Guaymas, Mexico. The geographical studies addressing this economic activity in Mexico and published in the last decades are scarce. For this reason, this research work is particularly important, as it outlines the fishery activities in one of the most active sea-ports of northwest Mexico, from a territorial perspective. The first part of this article explains why and how Economic Geography addresses fishery activities and which methodology we pursued to carry out this investigation, based on studies carried out by geographers, particularly in France and Argentina. Then the paper describes the natural conditions prevailing in the Gulf of California (also known as Sea of Cortez, a large inlet of the eastern Pacific Ocean that is rich in marine resources and where most of the main national fisheries are located. Guaymas is one of the most important sea ports located along the Gulf of California for its long fishing history and the variety of fishing species captured. This port, located in the southern coast of the state of Sonora, is a mediumsized city with a little over 100 thousand inhabitants; a considerable proportion of the local labor force works in the fishery sector and associated industries. Today, the fishery sector in Guaymas is characterized by a large number of artisan fishermen, a prominent fleet preciand the regular practise of illegal catching. This port is the seat of large enterprises, such as Ocean Garden, involved in the industrialization of catches (basically fish oil and fish meal and their further commercialization within and outside Mexico. Two commercially important species have played a key role in the evolution and outline of the current territorial structure of fisheries in Guaymas. One is shrimp, with a fishery that recorded a boom during 1970-1990, bringing along a number of benefits for local fishermen in Sonora. This fishery

Methods: A closed set of 45 representative environmental sounds were processed using two transposing (TRHA, TR1/3 and three modulating algorithms (AM, AMFM, AMMC and presented as tactile stimuli using a portable vibrator in three experiments. The algorithms TRHA, TR1/3, AMFM and AMMC had two alternatives (with and without adaption to vibratory thresholds. In Exp. 1, the sounds were preprocessed and directly fed to the vibrator. In Exp. 2 and 3, the sounds were presented in an acoustic test room, without or with background noise (SNR=+5 dB, and processed in real time. Results: In Exp. 1, Algorithm AMFM and AMFM(A consistently had the lowest identification scores, and were thus excluded in Exp. 2 and 3. TRHA, AM, AMMC, and AMMC(A showed comparable identification scores (30%-42% and the addition of noise did not deteriorate the performance. Discussion: Algorithm TRHA, AM, AMMC, and AMMC(A showed good performance in all three experiments and were robust in noise they can therefore be used in further testing in real environments.

    Full Text Available Background Territory owners usually defeat intruders. One explanation for this observation is the uncorrelated asymmetry hypothesis which argues that contests might be settled by an arbitrary convention such as “owners win.” We studied the effect of territorial residency on contest asymmetries in the white-eared hummingbird (Hylocharis leucotis in a fir forest from central Mexico. Methods Twenty white-eared male adult hummingbird territories were monitored during a winter season, recording the territorial behavior of the resident against intruding hummingbirds. The size and quality of the territory were related to the probability that the resident would allow the use of flowers by the intruder. Various generalized models (logistical models were generated to describe the probabilities of victory for each individual resident depending on the different combinations of three predictor variables (territory size, territory quality, and intruder identity. Results In general, small and low quality territory owners tend to prevent conspecific intruders from foraging at a higher rate, while they frequently fail to exclude heterospecific intruders such as the magnificent hummingbird (Eugenes fulgens or the green violetear hummingbird (Colibri thalassinus on any territory size. Our results showed that the identity of the intruder and the size and quality of the territory determined the result of the contests, but not the intensity of defense. Discussion Initially, the rule that “the resident always wins” was supported, since no resident was expelled from its territory during the study. Nevertheless, the resident-intruder asymmetries during the course of a day depended on different factors, such as the size and quality of the territory and, mainly, the identity of the intruders. Our results showed that flexibility observed in contest tactics suggests that these tactics are not fixed but are socially plastic instead and they can be adjusted to

  6. Trophic Niche in a Raptor Species: The Relationship between Diet Diversity, Habitat Diversity and Territory Quality.

    Navarro-López, Juan; Fargallo, Juan Antonio

    2015-01-01

    Recent research reports that many populations of species showing a wide trophic niche (generalists) are made up of both generalist individuals and individuals with a narrow trophic niche (specialists), suggesting trophic specializations at an individual level. If true, foraging strategies should be associated with individual quality and fitness. Optimal foraging theory predicts that individuals will select the most favourable habitats for feeding. In addition, the "landscape heterogeneity hypothesis" predicts a higher number of species in more diverse landscapes. Thus, it can be predicted that individuals with a wider realized trophic niche should have foraging territories with greater habitat diversity, suggesting that foraging strategies, territory quality and habitat diversity are inter-correlated. This was tested for a population of common kestrels Falco tinnunculus. Diet diversity, territory occupancy (as a measure of territory quality) and habitat diversity of territories were measured over an 8-year period. Our results show that: 1) territory quality was quadratically correlated with habitat diversity, with the best territories being the least and most diverse; 2) diet diversity was not correlated with territory quality; and 3) diet diversity was negatively correlated with landscape heterogeneity. Our study suggests that niche generalist foraging strategies are based on an active search for different prey species within or between habitats rather than on the selection of territories with high habitat diversity.

  7. Territory size decreases minimally with increasing food abundance in stream salmonids: Implications for population regulation.

    2017-10-01

    How the local density of territorial animals responds to changes in food abundance will depend on the flexibility of territory size. Quantitative estimates of territory size over a broad range of food abundance are relatively rare because of the difficulty of measuring food abundance in the wild. Stream salmonids are an ideal model system for investigating flexibility in territory size, because food abundance can be quantified in the field and manipulated in the laboratory. We conducted a meta-analysis to test whether territory size decreases with increasing food abundance, and a mixed model analysis to test among three competing predictions: with increasing food abundance, territory size will be (1) fixed-the slope of a regression of log territory size vs. log food abundance = 0; (2) flexible and decreasing, as if individuals are defending a fixed amount of food-a slope = -1; and (3) initially compressible, but with an asymptotic minimum size-a slope between 0 and -1. We collected data from 16 studies that manipulated or measured food abundance while monitoring changes in territory size of young-of-the-year salmonids; 10 were experimental laboratory studies, whereas six were observational field studies. Overall, territory size decreased significantly with increasing food abundance; the weighted average correlation coefficient was -0.31. However, the estimated slope of the relationship between log territory size and log food abundance was only -0.23, significantly different from 0, and also significantly shallower than -1. Our estimated slope suggests that attempts to increase the density of territorial salmonids by increasing food abundance and reducing territory size will be inefficient; a 20-fold increase in food abundance would be required to double population density. Our analysis may also have implications for other species with a territorial mosaic social system-i.e. contiguous territories. In these social systems, social inertia will dampen any effects

    The factors that determine the onset of the reproductive season and the relationship between territory defense and mating success of Colinus leucopogon males are unknown. Here I report on climatic variables influencing the time of permanence on the territory, and how this affects the species mating success. I also analyze the relationship between the time devoted by males on territory defense and the relationship of song and territorial characteristics. The onset of the reproductive season was determined by an amount of rain greater than 14.3 mm during March, favouring the food availability and nesting places abundance, and also allowed an increase in the reproductive success of Colinus leucopogon. The time invested in territory defense by males was not related with their mating success. Moreover, the duration in territory defense was similar for males that paired, compared with those that did not. In addition, song and territory characteristics were not related with males invested time in their territory defense. Therefore, this could be another reason explaining the lack of a relationship between the duration in the territories by males and pair formation, and suggests that song characteristics strongly influence the formation of pairs in this species.

    In fish species with alternative male mating tactics, sperm competition typically occurs when small males that are unsuccessful in direct contests steal fertilization opportunities from large dominant males. In the grass goby Zosterisessor ophiocephalus, large territorial males defend and court females from nest sites, while small sneaker males obtain matings by sneaking into nests. Parentage assignment of 688 eggs from 8 different nests sampled in the 2003–2004 breeding season revealed a high level of sperm competition. Fertilization success of territorial males was very high but in all nests sneakers also contributed to the progeny. In territorial males, fertilization success correlated positively with male body size. Gonadal investment was explored in a sample of 126 grass gobies collected during the period 1995–1996 in the same area (61 territorial males and 65 sneakers). Correlation between body weight and testis weight was positive and significant for sneaker males, while correlation was virtually equal to zero in territorial males. That body size in territorial males is correlated with fertilization success but not gonad size suggests that males allocate much more energy into growth and relatively little into sperm production once the needed size to become territorial is attained. The increased paternity of larger territorial males might be due to a more effective defense of the nest in comparison with smaller territorial males. PMID:23056415

    To examine how territorial males counter reproductive parasites, we examined the paternity of broods guarded by territorial males using 5 microsatellite loci and factors that determine siring success in a wild population of the Lake Tanganyika cichlid Lamprologus lemairii. Females enter rock holes (nests) and spawn inside, and territorial males release milt over the nest openings. Sneakers attempt to dart into the nests, but territorial males often interrupt the attempt. The body size of territorial males (territorial defense ability) and the size of nest opening (the ability to prevent sneakers from nest intrusions) are predicted to be factors that affect paternity at the premating stage, whereas milt quality traits are factors that affect paternity at the postmating stage. Parentage analyses of 477 offspring revealed that most clutches have few or no cuckolders, and territorial males sired >80% of eggs in 7 of the 10 analyzed clutches. Larger territorial males that spawned in nests with narrower openings had greater siring success. In contrast, none of the milt traits affected the siring success. These suggest that territorial male L. lemairii adopt premating strategies whereby they effectively prevent reproductive parasitism.

    Patients with moyamoya disease are frequently encountered with improved symptoms related to anterior cerebral artery territory (ACAt) and middle cerebral artery territory (MCAt) after bypass surgery at MCAt. To evaluate hemodynamic changes in MCAt and ACAt after bypass surgery in adult moyamoya disease. Combined bypass surgery was performed on 140 hemispheres in 126 patients with MCAt symptoms. Among them, 87 hemispheres (62.1%) accompanied preoperative ACAt symptoms. Clinical, hemodynamic, and angiographic states were evaluated preoperatively and approximately 6 months after surgery. Preoperative symptoms resolved in 127 MCAt (90.7%) and 82 ACAt (94.3%). Hemodynamic analysis of total patients showed a significant improvement in MCAt basal perfusion and reservoir capacity ( P < .001 and P = .002, respectively) and ACAt basal perfusion ( P = .001). In a subgroup analysis, 82 hemispheres that completely recovered from preoperative ACAt symptoms showed a significant improvement in MCAt basal perfusion and reservoir capacity ( P < .001 and P = .05, respectively) and ACAt basal perfusion ( P = .04). Meanwhile, 53 hemispheres that had never experienced ACAt symptoms significantly improved MCAt basal perfusion and reservoir capacity ( P < .001 and P = .05, respectively); however, no ACAt changes were observed. A qualitative angiographic analysis demonstrated a higher trend of leptomeningeal formation from MCAt to ACAt in the former subgroup ( P = .05). During follow-up, no ACAt infarctions were observed. Combined bypass surgery at MCAt resulted in hemodynamic improvements in ACAt and MCAt, especially in patients with preoperative ACAt symptoms.

    This study was conducted to ascertain current preferences for contact lens prescribing in the Australian states and territories. One thousand questionnaires were randomly distributed to proportionate samples of optometrists in each state of Australia. We requested details of the first 10 patients fitted with contact lenses after receipt of the questionnaire. One hundred and seventy-eight completed questionnaires were returned, detailing contact lens fits to 1,611 patients. The mean age of the patient group was 32.1 +/- 13.0 yrs (65 per cent female). For Australia as a whole: 53 per cent of patients were existing wearers, the remainder were new fits; 93 per cent of new fits were with soft lenses, of which seven per cent were for extended wear. Of the refits, 89 per cent were soft lenses and 18 per cent for extended wear. The lens material of first choice was mid-water-content (62 per cent of all soft lens fits). Only eight per cent of all soft fits were for lenses that were not replaced on a planned basis, with two weeks being the replacement interval of choice in all states and territories. The majority of rigid lenses were prescribed using mid-Dk materials (50 per cent). Analysis of solution prescribing indicates that multi-purpose products were the most common regimens for planned replacement soft lenses. The percentage of hydrogen peroxide prescribed increased as lens replacement became less frequent. By state or territory: practitioners in Tasmania prescribed more extended wear than those in any other state (p = 0.007) and practitioners in Queensland prescribed more daily disposable contact lenses than those in any other state (p = 0.009). Non-planned replacement lenses are now rarely prescribed to patients. Extended-wear lenses and rigid lenses continue to be prescribed more to existing contact lens wearers than to new patients. The impact of soft multifocal lens designs on contact lens prescribing is very small, ranging from 2.6 per cent in Queensland to 4

    On the territory of modern oil production soil, vegetation, ecosystem conditions of the environment are significantly transformed. Researches have been conducted on the oil production territories located in a boreal coniferous forest natural zone from 2005 to 2015. Standard geobotanical and soil methods are used. Mechanical destruction of a plant cover, change of the water conditions, intake of oil products and salty waters in ecosystems, pollution of the atmosphere are considered as the major technology-related factors defining transformation of land ecosystems at operation of the oil field. Under the mechanical destruction of a plant cover the pioneer plant communities are formed. These communities are characterized by most reduced specific wealth with prevalence of types of meadow groups of plants and presence of types of wetland groups of plants. The biodiversity of biocenosis which are affected linear infrastructure facilities of oil production territories and change of the water conditions, decreases. It is observed decrease in species wealth, simplification of structure of communities. Under the salting of soils in ecosystems there is a decrease species diversity of communities to prevalence nitrophilous and meadow plant species. At the increased content of organic substances in the soils that is a consequence of intake of oil products, is characteristic increase in specific richness of communities, introduction of types of wetland and oligotrophic groups of plants in forest communities. Influence depends on distance to an influence source. In process of removal from a source of atmospheric pollution in forest communities there is a decrease in species diversity and complication of structure of community. It is caused by introduction of types of meadow groups of plants in ecotone sites of the forest communities located near a source of influence and restoration of structural features of forest communities in process of removal from an influence source

    With the introduction of direct access to treatment from dental care professionals (DCPs) in 2013, dental nurses are being trained to support the wider dental team in a number of additional skills. The name for this expanded team role is Extended Duties Dental Nurse (EDDN). These new duties take the EDDN into new territories, one of which includes the issue of consent. This article explains the background to direct access and the extra responsibilities for EDDNs in terms of consent and indemnity. It explores the new knowledge required to gain valid consent and presents a scenario for consideration. The article concludes that it is important for EDDNs to develop their professional approach, taking early advice from the referring dentist and/or professional indemnity adviser if faced with an unfamiliar scenario.

This is a descriptive, qualitative study, using the Hidden Population reference to access the vulnerable and inaccessible populationand the Respondent Driven Sampling to reach the "hidden" population. The reference chain consisted of 90 families and we processed their responses by thematic content analysis, resulting in three themes: family interaction, religiosity and intrinsic factors and reasons for non-use of drugs; networks of support and interaction influencing the non-use of drugs; and occupational and educational factors and the distance from the daily life of drugs. Even in a neighborhood permeated by trafficking and violence, we identified protective factors and families whose members had never used drugs.

    Drink the milk of cows grazing near French nuclear power plants is it really safe in normal times? In case of a nuclear accident leading to release in the environment, what kind of foodstuff can we still eat? In his regulatory mission of environmental monitoring, the French Institute for Radiological Protection and Nuclear Safety (IRSN) tends to answer these questions by acquiring radioactivity data in the food chain. Food radiological monitoring program by IRSN is implemented with a three scale strategy. Locally, i.e. within the range 0 to 10 kilometers of nuclear installations, foodstuff locally produced and thus potentially exposed to radioactive sources are frequently sampled and analyzed. At the regional level, specific studies are carried out to establish an updated levels baseline of radioactivity in the environment, especially in agricultural productions characteristic of the area concerned. At the national level, monitoring food aims to map the average contamination observed all around the French territory. This work of vigilance is organized in partnerships with other French actors involved in food monitoring. In the event of a nuclear accident or small-scale incidents, it would allow having an efficient support network of samplers and measurers located on the whole French territory and quickly mobilized in short or medium terms. Since 2008, IRSN has developed a food monitoring program with the Directorate general for food (DGAL) and the Directorate general for competition policy, consumer affairs and fraud control (DGCCRF). These directions have a general mission of food safety control (animal and plant products) and animal feed-stuff, which requires the search for chemical, physical, biological and radioactive substances. Likewise, a sampling program of grain products is efficient since 1969 with the support of France Agrimer. In 2013, the food monitoring is based on multi-radionuclides analysis (cesium, iodine, tritium, alpha emitters...) in about 650

    Central Asia (CA) is an extremely large region of varied geography from plains to high, rugged mountains (the region belongs to the Tien-Shan and Pamirs mountain system), vast deserts (Kara Kum, Kyzyl Kum, Taklamakan). The area of the CA region is including the territories of following countries: of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. CA is particularly exposed to natural hazards like earthquakes, landslide, rockfalls, avalanches, mudflows, flooding, high mountains lakes, sub flooding, and debris flow. This region is one of the most seismically active in the world. In XX century almost in each of five countries have occurred strong earthquakes with magnitude more than 7, led to human victims. Loess soils are widespread in this region in foothills, foothill plains and intermountain depressions. Loess can cause a number of engineering problems because loess undergoes structural collapse and subsidence due to saturation when both the initial dry density and initial water content are low. By comparison of the map of seismic zoning to a map of distribution of loess soils it is easy to be convinced that the territory of the majority of seismic areas are covering by collapsible loess soils with significant thickness (50-150 m). The natural hazards leads to a disaster, if it develops in an urbanized or industrial areas and directly affects people and economic objects. In this case, risk takes place with all its consequences especially on loess soil. In the past a formation of natural hazards was connected generally with two main groups of factors: geological structure and climatic conditions. Now to them the third factor - of human made influence was added. Intensive influence of human activity to the loess territories in CA for last 60 years is destruction of nature balance and changing in environment of loess land in zone with high seismic hazard. This processes primarily associated with following: 1) irrigation of new lands; 2) the

    Full Text Available In 2007, Australia’s Commonwealth Government took a dramatic new approach to the governance of remote Indigenous communities. The ‘Northern Territory Intervention’ aimed to combat abuse and violence in remote Indigenous communities, and included far-reaching changes to welfare administration, employment programmes and policing. This paper considers a hitherto obscure aspect of the Intervention: the surveillance of publicly funded computers and internet use. Between 2007 and 2012, providers of internet and computer access facilities in the affected communities were required to audit and record computer use. In this paper we examine the legal and policy dimensions of this case of governmental surveillance, using interviews, published materials and documents obtained through freedom of information processes.

    Full Text Available AbstractThis article draws on an ethnographical study of indigenous Xakriabá boys, focusing on fieldwork that explores everyday practices that characterise the passage from domestic space to manhood through territory circulation. The hunt assumes an emblematic position in the learning process configuration that constitutes the male ethos of the Xakriabá. We review the unique arrangement of key practices, exploring their articulations and revealing learning processes developed both through the use of the scythe in agricultural work, and through hunting in the woods that surround the villages. Learning is explored as an inherent dimension of social practices. We highlight the relationships among different learning configurations in order to identify recurrent themes, such as peer interaction and co-responsability, which characterise particular ways of learning among the Xakriabá.

    2011-01-01

    In order to study how climate change affects the territory size of subterranean termites, a lattice model was used to simulate the foraging territory of the Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), and the minimized local rules that are based on empirical data from the development of termites' foraging territory was applied. A landscape was generated by randomly assigning values ranging from 0.0 to 1.0 to each lattice site, which represented the spatially distributed property of the landscape. At the beginning of the simulation run, N territory seeds - one for each founding pair, were randomly distributed on the lattice space. The territories grew during the summer and shrank during the winter. In the model, the effects of climate change were demonstrated by changes in two variables: the period of the summer season, T, and the percentage of the remaining termite cells, σ, after the shrinkage. The territory size distribution was investigated in the size descending order for the values of T (= 10, 15, ... , 50) and σ (= 10, 15, ... , 50) at a steady state after a sufficiently long time period. The distribution was separated into two regions: the larger-sized territories and the smaller-sized territories. The slope, m, of the distribution of territory size on a semi-log scale for the larger-sized territories was maximal with T (45 ≤ T ≤ 50) in the maximal range and with σ in the optimal range (30 ≤ σ ≤ 40), regardless of the value of N. The results suggest that the climate change can influence the termite territory size distribution under the proper balance of T and σ in combination.

    Pathogens can cause serious declines in host species, and knowing where pathogens associated with host declines occur facilitates understanding host-pathogen ecology. Suspected drivers of global amphibian declines include infectious diseases, with 2 pathogens in particular, Batrachochytrium dendrobatidis (Bd) and ranaviruses, causing concern. We explored the host range and geographic distribution of Bd and ranaviruses in the Taiga Plains ecoregion of the Northwest Territories, Canada, in 2007 and 2008. Both pathogens were detected, greatly extending their known geographic distributions. Ranaviruses were widespread geographically, but found only in wood frogs. In contrast, Bd was found at a single site, but was detected in all 3 species of amphibians in the survey area (wood frogs, boreal chorus frogs, western toads). The presence of Bd in the Northwest Territories is not congruent with predicted distributions based on niche models, even though findings from other studies at northern latitudes are consistent with those same models. Unexpectedly, we also found evidence that swabs routinely used to collect samples for Bd screening detected fewer infections than toe clips. Our use and handling of the swabs was consistent with other studies, and the cause of the apparent lack of integrity of swabs is unknown. The ranaviruses detected in our study were confirmed to be Frog Virus 3 by sequence analysis of a diagnostic 500 bp region of the major capsid protein gene. It is unknown whether Bd or ranaviruses are recent arrivals to the Canadian north. However, the genetic analyses required to answer that question can inform larger debates about the origin of Bd in North America as well as the potential effects of climate change and industrial development on the distributions of these important amphibian pathogens.

    Few studies have examined how landmarks affect territories' fundamental characteristics. In this field study, we investigated effects of landmarks on territory size, shape and location in a cichlid fish (Amatitlania siquia). We provided cans as breeding sites and used plastic plants as landmarks. During 10 min trials, we recorded locations where residents chased intruders and used those locations to outline and measure the territory. In two experiments, we observed pairs without landmarks and with either a point landmark (one plant) or linear landmark (four plants) placed near the nest can. We alternated which trial occurred first and performed the second trial 24 h after the first. Territories were approximately round without landmarks or with a point landmark but were significantly more elongated when we added a linear landmark. Without landmarks, nests were centrally located; however, with any landmark, pairs set territory boundaries closer to the landmark and thus the nest. Territory size was significantly reduced in the presence of any landmark. This reduction suggests that a smaller territory with well-defined boundaries has greater benefits than a larger territory with less well-defined borders.

    Preschoolers spend a substantial portion of their day in childcare; therefore, these centers are an ideal venue to encourage healthy active behaviors. It is important that provinces'/territories' childcare legislation encourage physical activity (PA) opportunities. The purpose of this study was to review Canadian provincial/territorial childcare legislation regarding PA participation. Specifically, this review sought to 1) appraise each provincial/territorial childcare regulation for PA requirements, 2) compare such regulations with the NASPE PA guidelines, and 3) appraise these regulations regarding PA infrastructure. A review of all provincial/territorial childcare legislation was performed. Each document was reviewed separately by 2 researchers, and the PA regulations were coded and summarized. The specific provincial/territorial PA requirements (eg, type/frequency of activity) were compared with the NASPE guidelines. PA legislation for Canadian childcare facilities varies greatly. Eight of the thirteen provinces/territories provide PA recommendations; however, none provided specific time requirements for daily PA. All provinces/territories did require access to an outdoor play space. All Canadian provinces/territories lack specific PA guidelines for childcare facilities. The development, implementation, and enforcement of national PA legislation for childcare facilities may aid in tackling the childhood obesity epidemic and assist childcare staff in supporting and encouraging PA participation.

  9. From Individual to Group Territoriality: Competitive Environments Promote the Evolution of Sociality.

    In many animal species individuals compete for the sole possession of a breeding territory, whereas in other species communal territories are shared among same-sex conspecifics. Under what conditions does natural selection favor the evolution of individual territoriality, and under what conditions does it favor the evolution of sociality? We develop a self-consistent game-theoretic model that allows for feedbacks between evolutionary and population dynamics. In this model, nonresident floaters can chose between three strategies: they can wait for a territory vacancy to arise, they can try to forcefully take over an already-occupied territory, or they can share a territory with an established resident. We show that competitive environments initially favor the evolution of an aggressive (territorial) strategy. Yet as competition increases further, a shift occurs from aggressive to social strategies. Moreover, territory owners (residents) respond to the behavior of floaters, such that a feedback occurs in which residents adjust their degree of tolerance to the level of floater aggression and vice versa. This feedback resembles the dynamics of a biological market and eventually leads to the coexistence of aggressive and social floater strategies in the population. Such mixed equilibria commonly occur in nature.

  14. Chromosome territory relocation paradigm during DNA damage response: Some insights from molecular biology to physics.

    2017-09-03

    Among the many facets of DNA damage response (DDR), relocation of chromosome territories (CTs) is most intriguing. We have previously reported that cisplatin induced DDR in human dermal fibroblasts led to relocation of CTs 12, 15 from the nuclear periphery to its interior while CTs 19, 17 repositioned from the interior to its periphery. Studies of CT relocation remain nascent as we begin unraveling the role of key players in DDR to demonstrate its mechanistic basis. Consolidating our recent reports, we argue that γH2AX-signaling leads to enhanced recruitment of nuclear myosin 1 (NM1) to chromatin, which via its motor function, results in CT repositioning. Next, we invoke a novel systems-level theory that subsumed CTs as pairs, not solo entities, to present the physical basis for plasticity in interphase CT arrangement. Subsequently, we posited that our systems-level theory describes a unified physical basis for non-random positioning of CTs in interphase nuclei across disparate eukaryotes.

    Tidal-signal attenuations are analyzed to compute hydraulic diffusivities and estimate regional hydraulic conductivities of the Northern Guam Lens Aquifer, Territory of Guam (Pacific Ocean), USA. The results indicate a significant tidal-damping effect at the coastal boundary. Hydraulic diffusivities computed using a simple analytical solution for well responses to tidal forcings near the periphery of the island are two orders of magnitude lower than for wells in the island's interior. Based on assigned specific yields of ˜0.01-0.4, estimated hydraulic conductivities are ˜20-800 m/day for peripheral wells, and ˜2,000-90,000 m/day for interior wells. The lower conductivity of the peripheral rocks relative to the interior rocks may best be explained by the effects of karst evolution: (1) dissolutional enhancement of horizontal hydraulic conductivity in the interior; (2) case-hardening and concurrent reduction of local hydraulic conductivity in the cliffs and steeply inclined rocks of the periphery; and (3) the stronger influence of higher-conductivity regional-scale features in the interior relative to the periphery. A simple numerical model calibrated with measured water levels and tidal response estimates values for hydraulic conductivity and storage parameters consistent with the analytical solution. The study demonstrates how simple techniques can be useful for characterizing regional aquifer properties.

    Summarize policies that support maternal and neonatal transport among states and territories. Systematic review of publicly available, web-based information on maternal and neonatal transport for each state and territory in 2014. Information was abstracted from published rules, statutes, regulations, planning documents and program descriptions. Abstracted information was summarized within two categories: transport and reimbursement. Sixty-eight percent of states and 25% of territories had a policy for neonatal transport; 60% of states and one territory had a policy for maternal transport. Sixty-two percent of states had a reimbursement policy for neonatal transport, whereas 20% reimbursed for maternal transport. Thirty-two percent of states had an infant back-transport policy while 16% included back-transport for both. No territories had reimbursement or back-transport policies. The lack of development of maternal transport reimbursement and neonatal back-transport policies negatively impacts the achievements of risk-appropriate care, a strategy focused on improving perinatal outcomes.

  18. ALWAYS COMING HOME: METIS LEGAL UNDERSTANDINGS OF COMMUNITY AND TERRITORY

    Directory of Open Access Journals (Sweden)

    Kerry Sloan

    2017-01-01

    Full Text Available Metis ideas of territory are complex, varied and often not well understood.  Metis perspectives on intersections of territory and community are likewise not appreciated by Canadian courts.  This is evident in the difficulties of Metis rights claimants in British Columbia, where misconceptions about Metis history and traditional use areas have resulted in courts questioning the existence of historic Metis communities in the province.  The leading case on Metis rights in Canada, R v Powley, requires claimants to prove there is a historic Metis community in an area where claimed rights are exercised.  In BC, courts following Powley in three cases – R v Howse, R v Nunn and R v Willison – have held there are no historic Metis communities in the Kootenays, the south Okanagan, or the Kamloops/Shuswap area.  Although these regions comprise only a portion of lands within provincial boundaries, the BC government takes the position there are no Metis communities in the province capable of meeting the Powley test, and thus asserts there can be no Metis Aboriginal rights holders in BC.      To challenge this position, and in order to illustrate the multiplicity and richness of Metis legal understandings of territory and community, the author braids family history, narrative, legal analysis and the perspectives of 23 Metis people from the southern BC interior who were involved in or affected by the Howse, Nunn and Willison cases.  The author suggests that expansive and nuanced Metis understandings of communities and territories cannot be encompassed by the Powley/Willison definition of a Metis community as “... a group of Métis with a distinctive collective identity, living together in the same geographic area and sharing a common way of life”.  While the court’s definition posits history, territory and community as separable, Metis views suggest these concepts are interlinked and mutually constitutive.    Les idées des Métis au

  19. Versatile and simple approach to determine astrocyte territories in mouse neocortex and hippocampus.

    Directory of Open Access Journals (Sweden)

    Antje Grosche

    Full Text Available BACKGROUND: Besides their neuronal support functions, astrocytes are active partners in neuronal information processing. The typical territorial structure of astrocytes (the volume of neuropil occupied by a single astrocyte is pivotal for many aspects of glia-neuron interactions. METHODS: Individual astrocyte territorial volumes are measured by Golgi impregnation, and astrocyte densities are determined by S100β immunolabeling. These data are compared with results from conventionally applied methods such as dye filling and determination of the density of astrocyte networks by biocytin loading. Finally, we implemented our new approach to investigate age-related changes in astrocyte territories in the cortex and hippocampus of 5- and 21-month-old mice. RESULTS: The data obtained by our simplified approach based on Golgi impregnation were compared to previously published dye filling experiments, and yielded remarkably comparable results regarding astrocyte territorial volumes. Moreover, we found that almost all coupled astrocytes (as indicated by biocytin loading were immunopositive for S100β. A first application of this new experimental approach gives insight in age-dependent changes in astrocyte territorial volumes. They increased with age, while cell densities remained stable. In 5-month-old mice, the overlap factor was close to 1, revealing little or no interdigitation of astrocyte territories. However, in 21-month-old mice, the overlap factor was more than 2, suggesting that processes of adjacent astrocytes interdigitate. CONCLUSION: Here we verified the usability of a simple, versatile method for assessing astrocyte territories and the overlap factor between adjacent territories. Second, we found that there is an age-related increase in territorial volumes of astrocytes that leads to loss of the strict organization in non-overlapping territories. Future studies should elucidate the physiological relevance of this adaptive reaction of

  20. Mountain Permafrost in the Yukon Territory, Canada: Mapping and Modelling

    The distribution and characteristics of mountain permafrost in North America are poorly known compared to lowland permafrost, and predictions of climatic change impacts are therefore subject to a higher degree of uncertainty. Recent DC resistivity soundings in association with borehole temperature information in the Yukon Territory, show the wide range of permafrost conditions that can exist at sites separated by short distances. To provide baseline information for future modelling, efforts are underway to produce a detailed map of permafrost probability in the mountains of the southern half of the Yukon Territory (60-65°N), an area greater than 200 x 103km2. The methodology is based on the Basal Temperature of Snow (BTS) technique, first developed in the European Alps. Ground surface temperatures measured at the base of snow > 80 cm thick in late winter are an indicator of permafrost presence or absence. We have used this method successfully in three study areas of about 200 km2: first, Wolf Creek basin near Whitehorse (Lewkowicz and Ednie, 2004) and now the western side of the Ruby Range adjacent to Kluane Lake, and the Haines Summit area in northwestern British Columbia. In each area, (1) we installed miniature temperature loggers at the ground surface and in the air to check on the timing of the BTS measurements; (2) we measured BTS values in the elevation zone across which permafrost was expected to become widespread; (3) we modelled the BTS spatial field using elevation (from a 30 m DEM) and potential incoming solar radiation (PISR) as the independent variables; and (4) we used logistic regression to compare the modelled BTS values with pit observations made in late-summer of the presence or absence of frozen ground. Both elevation and PISR were significant in the Wolf Creek and Ruby Range sites which have relatively continental climates and fall within the Upper Yukon-Stikine Basin climatic region (Wahl et al., 1987). For the Haines Summit area, however
