description: The aim of the present thesis was to study the economic benefits of festivals for the city where they are held at. In what ways the festivals contribute to the financial growth, how do festivals assist to the residents’ well being and how do they promote tourism. Our case study is Thessaloniki’s International Film Festival. Our purpose was to confirm the fact that the event contributes to the city’s financial growth and once we did, we wanted to define in what ways it does, the chances of further financial contribution and in what ways this could be achieved. We included a brief history report of the festival, a SWOT analysis and we held a research. The research method we used was public opinion survey and through the results of the questionnaires we created, we were able to extract the results that lead us to our conclusions.

description: We propose the implementation of a strongly-driven one-atom laser, based on the off-resonant interaction of a three-level atom in $Λ$-configuration with a single cavity mode and three laser fields. We show that the system can be described equivalently by a two-level atom resonantly coupled to the cavity and driven by a strong effective coherent field. The effective dynamics can be solved exactly, including a thermal field bath, allowing an analytical description of field statistics and entanglement properties. We also show the possible generation of Schrödinger cat states for the whole atom-field system and for the field alone after atomic measurement. We propose a way to monitor the system decoherence by measuring atomic population. Finally, we confirm the validity of our model through numerical solutions.

Στην έρευνα έλαβαν μέρος 17 υγιείς φοιτητές με μέσο όρο ηλικίας 21.7 ± 1.0 έτη, ύψος 184.0 ± 7.1 εκ. και μάζα 82.9 ± 9.4 κιλά. Πραγματοποιήθηκαν τρεις προσπάθειες για το καθένα από τα 5 επίπεδα δύναμης (5, 10, 20, 40 και 60% της Μέγιστης Εκούσιας Συστολής, ΜΕΣ) σε 3 γωνίες της ποδοκνημικής (75°, 90°: ανατομική θέση και 105°), με το γόνατο σταθερό σε γωνία 150°. Τόσο η απόλυτη (τυπική απόκλιση) όσο και η σχετικοποιημένη διακύμανση (Συντελεστής Διακύμανσης, ΣΔ) της δύναμης ήταν παρόμοια μεταξύ των γωνιών. Ο ΣΔ της δύναμης μειώθηκε από το 5 στο 10% της ΜΕΣ, από το 10 στο 20% της ΜΕΣ και στη συνέχεια σταθεροποιήθηκε στο 40 και 60% της ΜΕΣ, ανεξάρτητα από τη γωνία. Ο μέσος ρυθμός εκπόλωσης των ΚΜ ήταν υψηλότερος (p < 0.05) στις 75° (μικρότερο μήκος). Ωστόσο, η μεταβλητότητα των εκπολώσεων (ΣΔ του μεσοδιαστήματος των εκπολώσεων) και η μεταβλητότητα στη νευρική ενεργοποίηση (ΣΔ του φιλτραρισμένου αθροίσματος των εκπολώσεων) ήταν παρόμοιες (p > 0.05) σε όλες τις γωνίες της ποδοκνημικής. Οι τροποποιήσεις μήκους του πρόσθιου κνημιαίου δεν επηρεάζουν τις διακυμάνσεις της δύναμης πιθανώς λόγω της ομοιόμορφης διαμόρφωσης των χαρακτηριστικών εκπόλωσης των ενεργοποιημένων ΚΜ.
description: The purpose of the study was to assess the influence of short, intermediate and long muscular length on force steadiness and the discharge characteristics of motor units (MU) in Tibialis Anterior (TA) during low-to-moderate isometric dorsiflexions. Seventeen healthy young adults (21.7 ± 1.0 years, 184.0 ± 7.1 cm and 82.9 ± 9.4 kg) participated in this study. A range of 5 target forces (5, 10, 20, 40 and 60% of maximal voluntary contruction, MVC) was performed in 3 ankle angles (75°, 90°: anatomical position and 105°), with the knee fixed at 150°. Both absolute (standard deviation) and normalized amplitude (Coefficient of Variation, CoV) of the force were similar between angles. The CoV of force decreased from 5 to 10% MVC, from 10 to 20% MVC and then it plateaued at 40 and 60% of MVC, independent of angle. Mean discharge rate of TA MUs was higher (p < 0.05) at 75° (shorter length). However, discharge variability (CoV of interspike interval) and variability in neural activation (CoV of filtered cumulative spike train) were similar (p > 0.05) in all ankle angles. Length modifications of TA do not influence force fluctuations probably due to uniform modulation of the discharge characteristics of the involved MUs.

description: It is undeniable that people life patterns and technological developments are interrelated within a supply and demand cycle. In the education world, the emergence of the internet and mobile technologies has opened the learning boundaries through the use of mobile learning (m-learning). In Indonesia, the learning service industry has been begun to enliven the outside school education sector for almost five years ago. Even though the learning has been discussed around a decade ago, however, it is still rare studies that discuss the performance of the m-learning system based on the end-user perceptions in particular. Therefore, the study may still indispensable, especially from the perspectives of a developing nation. This paper elucidates the preliminary stage results of the above-mentioned study, including the results of the model development and its instrument testing. The DeLone and Mclean information system (IS) success model was adopted, combined with the individual motivation and organizational culture theories, and then adapted into the processional and causal logic of the success model. Around 50 respondent data were collected online and processed and analyzed based on the outer model assessments of the PLS-SEM method using SmartPLS 3.0 to know the reliability and validity of each indicator. The result shows that two of 31 are rejected indicators. The rejections may be the revision considerations for the next study stages. Although this may be trivial for experts, the clarity of its methodological explanations may guide the novice researchers, how to develop a research model and its instrument testing.

description: We report on an accurate measurement of the CXB in the 15-50 keV range performed with the Phoswich Detection System (PDS) instrument aboard the BeppoSAX satellite. We establish that the most likely CXB intensity level at its emission peak (26-28 keV) is ~40 keV/cm2/s/sr, a value consistent with that derived from the best available CXB measurement obtained over 25 years ago with the first High Energy Astronomical Observatory satellite mission (HEAO-1; Gruber et al. 1999), whose intensity, lying well below the extrapolation of some lower energy measurements performed with focusing telescopes, was questioned in the recent years. We find that 90% of the acceptable solutions of our best fit model to the PDS data give a 20-50 keV CXB flux lower than 6.5E-08 erg/cm2/s/sr, which is 12% higher than that quoted by Gruber et al. (1999) when we use our best calibration scale. This scale gives a 20-50 keV flux of the Crab Nebula of 9.22E-09 erg/cm2/s, which is in excellent agreement with the most recent Crab Nebula measurements and 6% smaller than that assumed by Gruber et al. (1999). In combination with the CXB synthesis models we infer that about 25% of the intensity at ~30 keV arises from extremely obscured, Compton thick AGNs (absorbing column density N_H > 1.0E+24 H/cm2), while a much larger population would be implied by the highest intensity estimates. We also infer a mass density of supermassive BHs of ~3.0E+05 Msol/Mpc3. The summed contribution of resolved sources (Moretti et al. 2003) in the 2-10 keV band exceeds our best fit CXB intensity extrapolated to lower energies, but it is within our upper limit, so that any significant contribution to the CXB from sources other than AGNs, such as star forming galaxies and diffuse Warm-Hot Intergalactic Medium (WHIM), is expected to be mainly confined below a few keV.

description: We consider Markov decision processes (MDPs) which are a standard model for probabilistic systems. We focus on qualitative properties for MDPs that can express that desired behaviors of the system arise almost-surely (with probability 1) or with positive probability. We introduce a new simulation relation to capture the refinement relation of MDPs with respect to qualitative properties, and present discrete graph theoretic algorithms with quadratic complexity to compute the simulation relation. We present an automated technique for assume-guarantee style reasoning for compositional analysis of MDPs with qualitative properties by giving a counter-example guided abstraction-refinement approach to compute our new simulation relation. We have implemented our algorithms and show that the compositional analysis leads to significant improvements.

description: We propose a framework to mine API usage scenarios from Stack Overflow. Each task consists of a code example, the task description, and the reactions of developers towards the code example. First, we present an algorithm to automatically link a code example in a forum post to an API mentioned in the textual contents of the forum post. Second, we generate a natural language description of the task by summarizing the discussions around the code example. Third, we automatically associate developers reactions (i.e., positive and negative opinions) towards the code example to offer information about code quality. We evaluate the algorithms using three benchmarks.

description: We present a flexible framework for the automated competitive analysis of on-line scheduling algorithms for firm- deadline real-time tasks based on multi-objective graphs: Given a taskset and an on-line scheduling algorithm specified as a labeled transition system, along with some optional safety, liveness, and/or limit-average constraints for the adversary, we automatically compute the competitive ratio of the algorithm w.r.t. a clairvoyant scheduler. We demonstrate the flexibility and power of our approach by comparing the competitive ratio of several on-line algorithms, including D(over), that have been proposed in the past, for various tasksets. Our experimental results reveal that none of these algorithms is universally optimal, in the sense that there are tasksets where other schedulers provide better performance. Our framework is hence a very useful design tool for selecting optimal algorithms for a given application.

description: A novel strategy to encrypt covert information (code) via unitary projections into the null spaces of ill-conditioned eigenstructures of multiple host statistical distributions, inferred from incomplete constraints, is presented. The host pdf's are inferred using the maximum entropy principle. The projection of the covert information is dependent upon the pdf's of the host statistical distributions. The security of the encryption/decryption strategy is based on the extreme instability of the encoding process. A self-consistent procedure to derive keys for both symmetric and asymmetric cryptography is presented. The advantages of using a multiple pdf model to achieve encryption of covert information are briefly highlighted. Numerical simulations exemplify the efficacy of the model.

description: The purpose of this research is to study the effect of a fitness training program on high-level football athletes, and to analyze the selected variables during a mid-cycle (4 weeks) of the season. The sample of this research consists of 20 high-class national football athletes selected from all the athletes who expressed interest in participating in this research. They were divided into a training group and a control group by random sampling. The measurements made, include recording altitude, aerobic capacity, and maximum eccentric, concentric and isometric strength. Initially the first measurement was made and then after the implementation of the intervention program the second measurement was completed. To test how the training program affects the athletes, a two way anova analysis was performed with repeated measurements (2X2). This was followed by independent t-test samples and paired t-test analysis. The statistical package SPSS 18.0 was used and the significance level was set at p <0.05. The results of the vertical jump from a fall of 30cm and squat jump there was an increase. In addition, an increase was observed in the recording of the maximum eccentric, concentric and isometric force. Finally, the maximum oxygen uptake remained stable without a statistically significant difference.

description: The critical resolved shear stress of an Al 4 wt. \% Cu alloy containing a homogeneous distribution of $θ''$ precipitates was determined by means of dislocation dynamics simulations. The size distribution, shape, orientation and volume fraction of the precipitates in the alloy were obtained from transmission electron microscopy observations while the parameters controlling the dislocation/precipitate interactions (elastic mismatch, transformation strains, dislocation mobility and cross-slip probability, etc.) were calculated from atomistic simulations. The precipitates were assumed to be either impenetrable or shearable by the dislocations, the latter characterized by a threshold shear stress that has to be overcome to shear the precipitate. The predictions of the simulations in terms of the critical resolved shear stress and of the dislocation/precipitate interaction mechanisms were in good agreement with the experimental results. It was concluded that the optimum strength of this alloy is attained with a homogeneous distribution of $θ''$ precipitates whose average size ($\approx$ 40 nm) is at the transition between precipitate shearing and looping. Overall, the dislocation dynamics strategy presented in this paper is able to provide quantitative predictions of precipitate strengthening in metallic alloys.

description: Bivariant (equivariant) K-theory is the standard setting for non-commutative topology. We may carry over various techniques from homotopy theory and homological algebra to this setting. Here we do this for some basic notions from homological algebra: phantom maps, exact chain complexes, projective resolutions, and derived functors. We introduce these notions and apply them to examples from bivariant K-theory. An important observation of Beligiannis is that we can approximate our category by an Abelian category in a canonical way, such that our homological concepts reduce to the corresponding ones in this Abelian category. We compute this Abelian approximation in several interesting examples, where it turns out to be very concrete and tractable. The derived functors comprise the second tableau of a spectral sequence that, in favourable cases, converges towards Kasparov groups and other interesting objects. This mechanism is the common basis for many different spectral sequences. Here we only discuss the very simple 1-dimensional case, where the spectral sequences reduce to short exact sequences.

description: Active learning is a decision-making process. In both abstract and physical settings, active learning demands both analysis and action. This is a review of active learning in robotics, focusing on methods amenable to the demands of embodied learning systems. Robots must be able to learn efficiently and flexibly through continuous online deployment. This poses a distinct set of control-oriented challenges -- one must choose suitable measures as objectives, synthesize real-time control, and produce analyses that guarantee performance and safety with limited knowledge of the environment or robot itself. In this work, we survey the fundamental components of robotic active learning systems. We discuss classes of learning tasks that robots typically encounter, measures with which they gauge the information content of observations, and algorithms for generating action plans. Moreover, we provide a variety of examples -- from environmental mapping to nonparametric shape estimation -- that highlight the qualitative differences between learning tasks, information measures, and control techniques. We conclude with a discussion of control-oriented open challenges, including safety-constrained learning and distributed learning.

description: In non-supersymmetric models of electroweak baryogenesis the top quark plays a crucial role. Its CP-violating source term can be calculated in the WKB approximation. We point out how to resolve certain discrepancies between computations starting from the Dirac equation and the Schwinger--Keldysh formalism. We also improve on the transport equations, keeping the W-scatterings at finite rate. We apply these results to a model with one Higgs doublet, augmented by dimension-6 operators, where our refinements lead to an increase in the baryon asymmetry by a factor of up to about 5.

Suicide in Hong Kong, 1981-1991 : a social and spatial analysis
Creators: name: Lee, David J.
Publisher: name: University of British Columbia

description: This thesis is a social and spatial study of suicide in Hong Kong's three subregions: Hong Kong Island, Kowloon, and the New Territories for the period 1981-1991. The primary data used are official suicide statistics; these are supplemented by descriptive newspaper accounts of suicide. Over time, the suicide rate for Hong Kong as a whole, as well as for each of these subregions, increased during this period. Over space, the rate was highest for Kowloon, a core urban area with the highest degree of social disorganization. The New Territories, a recently urbanized subregion, had the lowest but increasing rate. Moreover, it has been found that the suicide rates for all subregions increased lineally with age. It is hypothesized that the relatively high suicide rate for the older population is related to the inequitable social-wealth redistribution stemming from Hong Kong's laissez-faire economic policy, in particular, inadequate social services, inefficient public-sector medical services, and formal and informal suicide-intervention opportunities. It is also observed that Hong Kong's media provide most of its suicide coverage to the age group with the lowest suicide rate—school age people, while coverage given to elderly suicides is relatively rare and usually brief; this perpetuates public ignorance of elderly suicide as a problematic social issue. Increased equity in social-wealth redistribution and increased public awareness of depression and suicide are proposed as means of reducing suicide in Hong Kong.

description: Σκοπός της παρούσας μελέτης ήταν να διερευνηθούν οι διαφορές στα αρχιτεκτονικά χαρακτηριστικά του ημιτενοντώδη (ΗΤ) και της μακράς κεφαλής του δικέφαλου μηριαίου (ΜΚΔΜ). Για κάθε μεταβλητή σκοπός ήταν η σύγκριση ανάμεσα στις τρεις γωνίες γονάτου (0ο, 45ο,90ο) με τη θέση του ισχίου σταθερή (0ο). Συμμετείχαν 12 άτομα (6 άνδρες και 6 γυναίκες) χωρίς ιστορικό τραυματισμού και η απεικόνιση έγινε με υπέρηχο ευρέως οπτικού πεδίου και γραμμική διαδρομή ηχοβολέα μήκους 4,5 εκ. Το συνολικό μήκος της ΜΚΔΜ βρέθηκε μεγαλύτερο από του ΗΤ. Η γωνία γονάτου παρουσιάστηκε να επιδρά στο συνολικό μήκος της ΜΚΔΜ, στο συνολικό μήκος του ΗΤ και στο μήκος μυϊκής δεσμίδας του ημιτενοντώδη. Το σημείο μέτρησης παρουσίασε επίδραση στο μήκος μυϊκής δεσμίδας της ΜΚΔΜ και του ΗΤ, καθώς επίσης στη γωνία πτέρωσης της ΜΚΔΜ και του ΗΤ. Αλληλεπίδραση σημείου x γωνίας παρουσιάστηκε στο μήκος μυϊκής δεσμίδας της ΜΚΔΜ και του ΗΤ και στη γωνία πτέρωσης του ΗΤ. Συμπερασματικά, ο πανοραμικός υπέρηχος είναι μία έγκυρη μέθοδος απεικόνισης των αρχιτεκτονικών χαρακτηριστικών που επιτρέπει τη μελέτη τους, διευκολύνει στην κατανόηση της λειτουργίας των βιολογικών προσαρμογών που βασίζονται στην διαφορετικότητα των οπίσθιων μηριαίων και βοηθάει στον σχεδιασμό προπονητικών και θεραπευτικών μεθόδων.
description: The aim of the present study was to investigate the differences in the architectural parameters of the semitendinosus (ST) and the long head of the biceps femoris (BFlh). For each variable, purpose was the comparison between the three knee angles (0o, 45o, 90o) with the position of the hip fixed (0o). 12 people participated (6 men and 6 women) without a history of injuries and the imaging was done with ultrasound of an external field of view and a linear path of a 4.5 cm long transducer. The total length of the BFlh was found to be longer than the ST. The knee angle was shown to affect the total length of the BFlh, the total length of the ST and the fascicle length of the semitendinosus. The measuring point had an effect on the fascicle length of BFlh and ST, as well as on the pennation angle of BFlh and ST. An angle x point interaction occurred at the fascicle length of the BFlh and the ST and at the pennation angle of the ST. In conclusion, panoramic ultrasound is a valid method of visualizing the architectural features that allows their study, facilitates the understanding of the function of biological adaptations based on the difference of hamstrings and helps in the design of training and therapeutic methods.

description: ARES (Accelerator Research Experiment at SINBAD) is a linear accelerator at the SINBAD (Short INnovative Bunches and Accelerators at DESY) facility at DESY. ARES was designed to combine reproducible beams from conventional RF-based accelerator technology with novel but still experimental acceleration techniques. It aims to produce high brightness ultra-short electron bunches in the range of sub fs to few fs, at a beam energy of 100-150 MeV, suitable for injection into novel acceleration experiments like Dielectric Laser Acceleration (DLA) and Laser driven Plasma Acceleration (LPA). This paper reports the conceptual design and simulations of a final focus system for injecting into a LPA experiment at ARES, including permanent magnetic quadrupoles (PMQ), sufficient longitudinal space for collinear laser and electron transport, space for required diagnostics and a LPA setup. Space-charge effects play a significant role and are included. Simulation results on the focusing of the ARES electron bunches into and their transport through the laser-driven plasma are presented. The effects of several errors have been simulated and are reported.

description: The relationship between marriage and citizenship was implicit in the practices of most democratic states during the nineteenth and early twentieth centuries. The policy of depriving women who married foreigners of their citizenship was legally codified only with the process of ‘nationalisation’. In the particular case of Switzerland, the practice was not codified until 1941, at the height of the movement of peoples unleashed by the Second World War, and it was only fully dismantled in the 1990s. This article analyses the discursive webs linking gender construction, nation state and legal system during the controversies surrounding the marriage rule in Switzerland between 1917 and 1952. It explores the formative role of gender in the process of delineating the practices of inclusion and exclusion and in shaping the internal boundaries within the nation between foreigners and those who belonged: citizens.

description: We re-examine the correlation between the frequencies of upper and lower kHz quasi-periodic oscillations (QPO) in bright neutron-star low-mass X-ray binaries. By including the kHz QPO frequencies of the X-ray binary Cir X-1 and two accreting millisecond pulsars in our sample, we show that the full sample does not support the class of theoretical models based on a single resonance, while models based on relativistic precession or Alfven waves describe the data better. Moreover, we show that the fact that all sources follow roughly the same correlation over a finite frequency range creates a correlation between the linear parameters of the fits to any sub-sample.

description: The accumulation and penetration of antitumor drugs in tumor tissues are directly related to their antitumor effects. The particle size of the nanodrug delivery system is one of the most important factors for the accumulation and penetration of antitumor drugs within tumor tissues. Generally, nanodelivery systems of intermediate size (100–120 nm) are capable of efficient accumulation owing to prolonged circulation and enhanced permeability and retention (EPR) effect; however, smaller ones (20–40 nm) are effective for deep penetration within tumor tissue. Currently a conventional drug delivery system cannot possess two types of optimal sizes, simultaneously. To solve this and to enhance cervical cancer treatment, a furin-responsive triterpenine-based liposomal complex (PEGcleavable Tf-CTM/L), with Tf-CTM (transferrin-modified tripterine-loaded coix seed oil microemulsion) in core, coated with a thermo-sensitive lipid and a kind of PEG shell modified with a furin-cleavable peptide was developed to improve tumor-specific accumulation and penetration. Herein, PEGcleavable Tf-CTM/L was capable of efficient accumulation because of EPR effect. The PEG shells could timely detach under stimulation of overexpressed furin protein to solve the problem of the steric hindrance dilemma. The small-sized Tf-CTM released under stimulation of tumor microthermal environment in cervical cancer, which was efficient with regards to deep penetration at tumor sites. Notably, compared to the use of triterpenine alone, PEGcleavable Tf-CTM/L promoted anticervical efficacy and displayed diminished systemic toxicity by efficient accumulation and deep penetration of antitumor drugs within tumor tissues. Our study provides a new strategy, and holds promising potential for anticervical cancer treatment.

description: We consider an open string version of the topological twist previously proposed for sigma-models with G2 target spaces. We determine the cohomology of open strings states and relate these to geometric deformations of calibrated submanifolds and to flat or anti-self-dual connections on such submanifolds. On associative three-cycles we show that the worldvolume theory is a gauge-fixed Chern-Simons theory coupled to normal deformations of the cycle. For coassociative four-cycles we find a functional that extremizes on anti-self-dual gauge fields. A brane wrapping the whole G2 induces a seven-dimensional associative Chern-Simons theory on the manifold. This theory has already been proposed by Donaldson and Thomas as the higher-dimensional generalization of real Chern-Simons theory. When the G2 manifold has the structure of a Calabi-Yau times a circle, these theories reduce to a combination of the open A-model on special Lagrangians and the open B+\bar{B}-model on holomorphic submanifolds. We also comment on possible applications of our results.

Transformation of Brassica napus cv. Westar with the beet western yellows virus coat protein gene
Creators: name: Lee, Lawrence
Publisher: name: University of British Columbia
Year: 2008

description: Double stranded (ds) complementary DNA (cDNA) copies of the beet western yellows virus (BWYV) coat protein (CP) gene were synthesized from genomic BVVYV RNA using reverse transcriptase (RT) followed by the polymerase chain reaction (PCR). The ds cDNA copy of the BWYV CP was then cloned into plasmid pRT103, a plant expression vector which contains the cauliflower mosaic virus (CaMV) 35S promoter and polyadenylation signal. The CP cDNA was inserted in the plus-sense orientation (clone BW102D) and in the anti-sense orientation (clone BW137D) relative to the CaMV 35S promoter. The CP coding regions of both pRT103 constructs were sequenced and found to correspond closely to those of previously published BWYVCP sequences. In vitro translation analysis in wheat germ extracts of synthetic transcripts of the cloned BWYV CP DNA produced only one major protein of ca. 22.5kDa, the expected size for the BWYV coat protein. The CaMV 35S promoter-BWYVCP-polyadenylation cassette from clones BW102D and BW137D were then cloned separately into the Hind III restriction enzyme site between the left and right borders of the T-DNA region and next to the npt II cassette of the two binary plasmids, pCGN1548 and pCGN1557 (Calgene). After mobilization of the four resulting binary plasmid constructs (pCGN154802, pCGN154837, pCGN155702 and pCGN155737) into Agrobacterium tumefaciens EHA101, the A. tumefaciens were used in the plant transformation procedure described by Moloney et al. (1989) utilizing cotyledonary explants of Brassica napus cv. Westar. Thirty eight regenerated plants were recovered under the selection of the antibiotic, kanamycin. Southern blot analysis of Hind digested plant DNA indicated that the BWYV CP gene was present in the genome of three transformed plants (154802-1, 154802-3 and 1557-7). PCR analysis of the same plant genomic DNA followed by Southern blot analysis of the PCR products indicated that several plants contained the BWYV CP gene integrated into the plant genome (plants 155702-1 to -8, -10 to -14, 1557-7 and 154802-1 to -5). RNA transcripts of either the BWYV CP gene or the co-transformed npt II gene could not be detected using Northern blot analysis of the RNA extracted from regenerated plants. However, germination of the R1 seeds from the regenerated plants on kanamycin indicated that the npt II gene product which confers kanamycin resistance was functional in many of the progeny of the regenerated plants. BWYV CP subunits could not be detected byenzyme-linked immunosorbent assay (ELISA) using a polyclonal antiserum which reacts with BWYV CP subunits. Preliminary evaluation of the progeny of two promising lines (154802-3 and 1557-7), demonstrated to have the BWYV CP gene integrated into the plant genome, did not reveal significant levels of resistance when challenged with the homologous virus using the aphid vector, Myzus persicae (Sulz.)

description: Strong correlations between equilibrium fluctuations of the configurational parts of pressure and energy are found in the Lennard-Jones liquid and other simple liquids, but not in hydrogen-bonding liquids like methanol and water. The correlations, that are present also in the crystal and glass phases, reflect an effective inverse power-law repulsive potential dominating fluctuations, even at zero and slightly negative pressure. In experimental data for supercritical Argon, the correlations are found to be approximately 96%. Consequences for viscous liquid dynamics are discussed.
