title: Structure-function analysis of the transcriptional regulator TZP in Arabidopsis thaliana
Creators: name: Davidson, Mhairi Louise Hope
Publisher: name: University of Glasgow
Year: 2021
Subjects: subject: Plant science, Arabidopsis, photobiology, light

description: Light signalling is vital to the control of development in plants. TANDEM ZINC-FINGER PLUS3 (TZP) is a transcriptional regulator which has been shown to mediate light-responsive developmental transitions in Arabidopsis. During photomorphogenesis for example, hypocotyl growth is positively regulated by TZP in low blue light. Furthermore, TZP localises to transcriptionally active nuclear bodies. This thesis aims to understand the structure-function relationship of TZP in blue-light mediated hypocotyl growth. Hypocotyl elongation-promoting genes are co-regulated by TZP and its interacting partner the transcription factor ZFHD10 in blue light. TZP also interacts with the blue light photoreceptor cry1 in planta. TZP contains tandem zinc-fingers (ZFs) and a Plus3 domain at the C-terminus. Deletion analysis suggests the TZPZF-Plus3 region is sufficient to rescue the short hypocotyl phenotype of the tzp mutant in blue light. Whereas, TZP nuclear body formation requires the N-terminus which has no predicted structure. Within the Plus3 domain, TZP has a putative Ethylene-responsive element binding factor-associated Amphiphilic Repression (EAR) motif. EAR motifs are typically found in active transcriptional repressors, however, TZP does not show repressive activity in a fluorescence-based assay for transcriptional repression. Also, the ability of TZP to promote blue light-mediated hypocotyl elongation is not affected by the absence of the potential EAR motif. In addition to protein structure, post-translational modification of TZP may have a role in regulating hypocotyl growth. SUMOylation is the reversible attachment of a SUMO protein to a lysine within the target protein. In a proteomic analysis for proteins bound to a SUMO1 variant, TZP was identified as a SUMO conjugate when plants undergo heat-stress. The amino acid sequence of TZP contains six SUMOylation sites predicted by two algorithms, one plant-specific. TZP’s role in promoting hypocotyl elongation in blue light is inhibited by the absence of these sites, which indicates SUMOylation may regulate TZP function. Overall, these findings support the relationship between TZP structure and function in the regulation of plant development.

description: STATEMENT INDICATING INTENT AND THOUGHT During the last few years and including time spent in the post-graduate diploma course at Curtin University, my work has increasingly been concerned with the way meanings are constructed. I am particularly interested in the differences between such categories of meaning as \serious\" \"humorous\" etc and the boundaries that exist in language which determines these categories. Much of my work has been to subvert these boundaries and to create incidents or events that are anomalous that is that which can't be easily placed in such a category. For instance visual puns to do with houses can be both serious and humorous given the chance of being manipulated. I am also interested in the way written or cypher language is translated to the visual and again the potential of such translation for subversion i.e. \"The Door is ajar\" can mean what it says and can look like the door as \"a jar\". It is the translation of written or spoken grammar into the visual where I see much potential and fun for making art. Words and their meanings or mis-interpretations fascinate me. I want to play with visual imagery in the same way punning misquoting and generally subverting the written language is used by authors to create humour. In my current work I am building fifty snow shakers of the souvenir type. The language structures of these popular almost kitch items interests me for their ability to create humour and play. Firstly I am working on the fact that these items in themselves represent the type of mass imagery presented to us through the use of the media where one image just blends into the next:- Mass produced products create mass produced images and secondly the juxtaposition of written and verbal language which often present say the name of a city or country with an image set together inside the snow shaker. This relationship is usually open to plenty of abuse! Roland Bathes essay on the written text's ability to anchor the visual image is the type of theory underpinning my work. Where the images are changed by their relationship to written language. It is in this area that I am interested. All this is conditional by my belief that art should be fun and work to create communication between artist and audience."

description: Prevalence studies in the AAC discipline are fundamental to establishing funding, instructional, and research priorities. These data inform policy-makers on the allocation of clinical and educational services, help prioritize AAC pre-service and in-service trainings, and support AAC research grant applications. A survey study was designed to (a) provide prevalence estimates of school-age students who have highly unintelligible speech, (b) describe the demographic makeup of these students, and (c) describe their access to AAC. Rigorous web-based survey development and distribution procedures were followed. Special education administrators in New Mexico, USA were recruited to distribute the surveys to speech-language pathologists (SLPs) in their respective school districts. The majority of school districts in the state participated, and the overall SLP response rate for participating districts was high (65%). Based on the results, the best estimate indicates that approximately 1 in 89 school-age students in New Mexico has severely unintelligible speech. SLPs averaged 5.4 students per caseload with severely unintelligible speech, with 86% of SLPs providing services to at least one of these students. Only 22% of students with highly unintelligible speech had been seen by an AAC specialist. The findings highlight the substantial number of school-age students with highly unintelligible speech and the ongoing need for high quality AAC service provision for these students.

description: Waves are superoscillatory where their local phase gradient exceeds the maximum wavenumber in their Fourier spectrum. We consider the superoscillatory area fraction of random optical speckle patterns. This follows from the joint probability density function of intensity and phase gradient for isotropic gaussian random wave superpositions. Strikingly, this fraction is 1/3 when all the waves in the two-dimensional superposition have the same wavenumber. The fraction is 1/5 for a disk spectrum. Although these superoscillations are weak compared with optical fields with designed superoscillations, they are more stable on paraxial propagation.

description: For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more accurately with the video clip than with spoken cues only, and significantly more accurately with spoken cues only relative to the sequence of graphic symbols. Results suggest that the short video clip along with spoken cues may be an optimal mode for enhancing learners’ ability to follow directives containing prepositions. In addition, results reveal three statistically significant correlations between participants’ preexisting skills and directive-following accuracy: a positive correlation between spoken preposition preassessment total score and accuracy in the spoken-alone condition; a positive correlation between spoken noun preassessment total score and accuracy in the video-clip condition; and a positive correlation between ASD severity and the need for repetition in the video-clip condition. Results also suggested that, for children with more severe ASD symptoms, the video clips require repetitions so that the relationships illustrated within it can gain more semantic salience. Implications for clinical practice and future research are discussed.

description: In this paper, we generalized the surface integral equation method for the evaluation of Casimir force in arbitrary three-dimensional geometries. Similar to the two-dimensional case, the evaluation of the mean Maxwell stress tensor is cast into solving a series of three-dimensional scattering problems. The formulation and solution of the three-dimensional scattering problem is well-studied in classical computational electromagnetics. This paper demonstrates that this quantum electrodynamic phenomena can be studied using the knowledge and techniques of classical electrodynamics.

description: M.F.A. Proposal, Joanna Flynn, March 1988. My interest is in narratives. This has developed over the last two or three years, from a way of constructing pictures to a wish to focus on narrative as the content as well as the vehicle. I intend an exploration of the idea of personal and private narrative, juxtaposed with public narrative, eg. as these narratives are intended to be a unified assemblage of disparate parts, both textual and pictorial; using personal poems, firsthand anecdotes, my own fiction and quotes from other personal sources, also private photographs, drawings and jokes, and on the public side; documents, archival material relating to legislative and judicial decisions made by community councils in Australia and England, used sparingly. The narratives shall then, be both written and illustrated. I shall employ the services of a ghost hero, a sort of hold-all animus who becomes the itinerant master of ceremonies or the eternal victim, the artist as a young manimus if you like. (Why? Because every good narrative needs a hero and I don't have the shoulders for it). My role as an artist is evocative. At the minute I intend my influences for these pictures to be, the photo-print collages from the 60's and early 70's of Robert Rauschenberg;,his pictures of America, the 'Stoned Moon' series. Also, the powerful Mayakovsky exhibition that toured Australia last year which showed the process of deification (of the artist), through the use of photographs and biographical material, and as well, the writings of Richard Brautigan, the sixties pop poet of San Francisco. The works of these two artists were terribly evocative of the time in which they were manufactured but are sufficiently successful as works of art, not to have simply become period pieces.

description: No abstracts are to be cited without prior reference to the author. NOAA Fisheries and partners are developing the Spatial Economics Toolbox for Fisheries (FishSET) to improve predictions about fleet behavior, enabling better management of marine resources and more effective design of marine protected areas (MPAs). FishSET organizes data with data management tools, establishes best practices for all aspects of modeling, packages a range of state-ofthe-art fisher location choice models, and provides tools to compare the economic impacts of different potential MPAs. Here we provide an overview of the modeling approach, project implementation, and FishSET software. Pilot projects that utilize FishSET are underway in different regions of the United States, ensuring that the data challenges that confront modelers in different regions are addressed at the onset of the project. Implementing pilot projects in various environments also provides insight into how economic and fisheries data requirements for effective management may vary across different types of fisheries. We present examples from Alaska to the Gulf of Mexico of how FishSET is being used to estimate the economic impacts of different potential marine closures and other management actions.

title: “Can Home-Based High Intensity Interval Training Improve Post Exercise Glycaemic Control in People with Type 1 diabetes?”
Creators: name: Pickles, J
Publisher: name: Liverpool John Moores University
Year: 2021

description: Aims: The aims of this study were to investigate: the effects of home-HIIT and home-MICT completed in a postprandial state compared to a non-exercise control period on; i) hypoglycaemia ii) time in range (TIR), and iii) glycaemic variability (GV), for up to 48-hours post exercise in a free-living environment in adults with Type 1 diabetes. A secondary aim was to investigate whether acute changes following exercise influenced 14-day glycaemic control. Methods: 11 adults with Type 1 diabetes (male n=4, female n=7, age 26 ± 7 years, BMI 25.43 ± 4.29 kg.m2, Type 1 diabetes duration 10 ± 8 years) completed a randomised crossover study consisting of three 14-day interventions; 1) home-HIIT, 2) home-MICT and 3) non-exercise control (CON). During exercise intervention the effect of six exercise sessions on subsequent glycaemic control was assessed for up to 48-hours post exercise. CON data was time matched to home-HIIT. Glycaemic control was measured using an Abbot Freestyle Libre flash glucose monitor. Dietary intake and insulin dose were also assessed. Results: Neither home-HIIT or home-MICT increased time spent in serious, clinically significant hypoglycaemia (< 3.0 mmol/L) compared to CON at any period during the 48 hours post exercise (P > 0.05). TIR in home-HIIT was significantly greater during the period immediately after exercise compared to CON (11% [0, 22], P = 0.043) and significantly greater compared to home-MICT during the awake periods on the day following (10% [2, 18], P = 0.013) and second day following exercise (11% [3, 20], P = 0.014). GV, assessed as coefficient of variation (CV) was increased during the nocturnal period on the second day following home-MICT compared to CON (CV = 4% [1, 7] P = 0.008) and home-HIIT (CV = -5% [-8, 2], P = 0.005). This increase in GV translated into an increased nocturnal GV over the 14-day day intervention period in home-MICT compared to home-HIIT (CV = -4% [-8, 0], P = 0.034). Conclusion: In conclusion, both home-HIIT and home-MICT are safe exercise modalities for people with Type 1 diabetes but Home-HIIT may provide more beneficial effects on glycaemic control compared to home-MICT. This study provides novel evidence that exercise affects glycaemic control for up to 48-hours post exercise in people with Type 1 diabetes.

description: By an exact formulation of tunnelling into a multi-band superconductor in terms of Green's functions, we demonstrate that the multi-band feature of the iron-based superconductors can lead to novel interference between Andreev reflections and decoherence effect of quasi-particles to Andreev reflections in a tunnelling junction. These effects depend on the relative sign of the gaps for s-wave pairing, and the sign of the Fermi velocities also matters for tunnelling along the nodal direction of d-wave gaps. Experimental probe of such effects could determine both the pairing symmetry and the relative sign of the gaps on different bands.

description: The percolation of a liquid through a porous material is investigated with the help of equations of the Onsager type. An expression is derived for the molecular attraction, starting from Sutherland's potential approximation to the van der Waals interaction. Then appropriate Onsager equations incorporating this molecular attraction are written from transport theory considerations, in terms of dimensionless variables. As an application, the system of self-similar equations so derived is applied to a simplified situation.

Pulsed nuclear magnetic resonance in metal single crystals

Publisher: name: University of British Columbia
Year: 2011

description: The study of pulsed n. m. r. in single crystal metallic samples, initiated by McLachlan, has been extended to liquid helium temperatures with special emphasis on Sn¹¹⁹ . Contrary to McLachlan's belief it was found that cooling to 4. 2°K and lower afforded significant improvements to the signal to noise ratio and in many cases the n. m. r. signals (including spin echoes in Sn¹¹⁹ ) could readily be seen on an oscilloscope without the use of a signal averager. The theory of magnetic resonance in metallic samples was studied in some detail with particular emphasis on the experimental situation where matters are complicated by the high conductivity which modulates both the amplitude and the phase of the exciting r.f. magnetic field as it penetrates into the sample. It is shown theoretically that several assumptions must be made to show that the conventional methods of pulsed n. m. r. used to measure T₂ (by either spin echo or free induction decay) and T₁ yield true meaningful results. In particular it is found that the spin lattice relaxation time T₁ is obtained by the conventional two pulse sequence only when the magnetic field is exactly on resonance; this was observed to be the case experimentally as well. In sharp distinction to McLachlan's findings for Sn¹¹⁹, the spin-spin relaxation time T₂ obtained by FID methods (175 ± 18μsec) was much smaller than that obtained by spin echo techniques (390 ± 48μsec) in the present research on Sn¹¹⁹. The spin-lattice relaxation time was also measured at liquid helium temperatures and yielded a value of 56 ± 4 millisec deg for T₁, in excellent agreement with Dickson although twice as large as McLachlan’s value.

description: Theoretical work predicts that the strong dependence of Tc on pure shear strain within the a-b plane of optimally doped YBa2Cu3O{7-delta} results in heterogenous columnar pins of vortex lines about dislocation lines and about nano-columns inclusions aligned in parallel to the c axis. The critical current of a rigid vortex lattice driven by the Lorentz force in the presence of such clusters of pin/antipin lines is computed using two-dimensional (2D) collective pinning theory and by numerical simulation of the corresponding 2D vortex dynamics. Both theory and computer calculation find that the antipin component of the heterogenous columnar pins contributes substantially to the net in-field critical current.

description: No abstracts are to be cited without prior reference to the author. The MPA « Parc naturel marin d’Iroise » (PNMI) aims to know and protect the marine environment and promote sustainable maritime activities. In this MPA, kelps form large underwater forests that dominate the low intertidal to high subtidal zone and two kelp species are currently harvested: Laminaria digitata and Laminaria hyperborea. Our aim was to explore the conservation value of the PNMI regarding kelp forest biodiversity by characterizing and comparing this zone to other regions of Brittany regarding environmental conditions, genetic diversity of the two harvested kelp species and species diversity of seaweed communities living beneath the kelp canopy. We showed that, together with the Morlaix Bay, the PNMI constitutes a cold resilient water pocket surrounded by warmer and less resilient ones. The use of genetic tools revealed that both L. digitata and L. hyperborea populations exhibit high levels of genetic diversity within the PNMI and the Morlaix Bay; moreover, our results suggested that L. digitata populations in these two regions display unique genetic diversity and may have an exporting role to adjacent regions. The PNMI and the Morlaix Bay also displayed highly diverse seaweed communities and might constitute a refuge area from climate change for some red seaweed species.
Critical velocities and generation of vorticity in liquid helium II in large pipes of rectangular cross-section at 1.40 K
Creators: name: Slater, Williams James
Publisher: name: University of British Columbia
Year: 2011

description: Critical velocities have been measured in liquid helium at 1.40 K for counterflow, superflow and counterflow superimposed on superflow. The measurements were made in five pipes having rectangular cross-sections and ranging in size nominally from 0.2 x 1.2 x 10 cm to 1.2 x .1.2 x 10 cm. The turbulence was detected by means of negative ion currents perpendicular to the flow. The results are interpreted in terms of creation of quantized vortex lines. For superflow, the critical velocities were slightly higher but within the experimental range of those measured for counterflow. For the case of superflow-plus-counterflow a second critical point was observed, in addition to the one corresponding to superflow only. Considerable data was also collected regarding the nature of the ionic current attenuation effects for supercritical flow. The delay times between when the flow rate was raised to or above the critical velocity and when the current attenuations were first observed ranged from more than five minutes for the smallest pipe to three-quarters of a minute or less for the largest one. When the pipe width is greater than the ion source width the attenuations may be explained by Vinen's theory of vortex generation and decay but for smaller pipe widths the attenuation buildup and decay times are greatly increased. A method for increasing the sensitivity of the detection method for large pipes is also outlined.
An Improved Method for Using MgII to Estimate Black Hole Masses in Active Galactic Nuclei

description: We present a method for obtaining accurate black hole (BH) mass estimates from the MgII emission line in active galactic nuclei (AGNs). Employing the large database of AGN measurements from the Sloan Digital Sky Survey (SDSS) presented by Shen et al., we find that AGNs in the redshift range 0.3-0.9, for which a given object can have both H-beta and MgII line widths measured, display a modest but correctable discrepancy in MgII-based masses that correlates with the Eddington ratio. We use the SDSS database to estimate the probability distribution of the true (i.e., H-beta-based) mass given a measured MgII line width. These probability distributions are then applied to the SDSS measurements from Shen et al. across the entire MgII-accessible redshift range (0.3-2.2). We find that accounting for this residual correlation generally increases the dispersion of Eddington ratios by a small factor (~0.09 dex for the redshift and luminosity bins we consider). We continue to find that the intrinsic distribution of Eddington ratios for luminous AGNs is extremely narrow, 0.3-0.4 dex, as demonstrated by Kollmeier et al. Using the method we describe, MgII emission lines can be used with confidence to obtain BH mass estimates.

description: The use of multi-sensing portable analysers is of increasing importance for many applications. This thesis reports on the development of new portable battery-powered gas analysers suitable for remote site monitoring that can utilise a range of Taguchi tin-oxide sensors as detectors. Two main designs were developed and evaluated for a variety of applications employing head-space analysis. A portable analyser employing the TGS812 and TGS824 Taguchi gas sensors was built in flow-through arrangements. The performance of the gas analyser was evaluated in terms of reproducibility, stability and sensitivity and was used to determine the ethanol content in various commercial beer and wine samples. The adsorption response mechanism of the tin-oxide gas sensors was also investigated using the Langmuir adsorption isotherm model and this model was validated by determining the ethanol content of beer and wine samples. A portable, battery-powered, multi-sensor gas analyser, containing six different Taguchi tin-oxide semiconductors was developed and evaluated. The performance of the portable, battery-powered, multi-sensor gas analyser was evaluated in terms of stability, sensitivity, selectivity and reproducibility. The portable multi-sensor gas analyser was used to determine the ethanol content in various beer samples employing the Langmuir isotherm mentioned above. The portable battery-powered multi-sensor gas analyser mentioned above was used together with back-propagation artificial neural networks and applied to discriminate between beer brands, grades of olive oils, as well as the estimation of the age of olive oil samples.

description: The dielectric susceptibility of most materials follows a fractional power-law frequency dependence that is called the "universal" response. We prove that in the time domain this dependence gives differential equations with derivatives and integrals of noninteger order. We obtain equations that describe "universal" Curie-von Schweidler and Gauss laws for such dielectric materials. These laws are presented by fractional differential equations such that the electromagnetic fields in the materials demonstrate "universal" fractional damping. The suggested fractional equations are common (universal) to a wide class of materials, regardless of the type of physical structure, chemical composition or of the nature of the polarization.

In order to realize the full potential of this material the fabrication techniques of graphene devices, still in their infancy, need to be refined to better isolate the graphene layer from the environment. We present results from a study on the influence of extrinsic factors on the quality of graphene devices including material defects, lithography, doping by metallic leads and the substrate. The main finding is that trapped Coulomb scatterers associated with the substrate are the primary factor reducing the quality of graphene devices. A fabrication scheme is proposed to produce high quality graphene devices dependably and reproducibly. In these devices, the transport properties approach theoretical predictions of ballistic transport.

description: No abstracts are to be cited without prior reference to the author. Few field studies have investigated how changes at one trophic level can affect the invasibility by aliens of other trophic levels. We examined the hypothesis that the spread of the introduced green alga Caulerpa racemosa (Forsskål) J. Agardh in degraded seagrass beds of the key-stone species Posidonia oceanica (L.) Delile depends on the depletion of large consumers such as the fishes Salpa sarpa (Linneo, 1758) and Diplodus sargus sargus (Linneo, 1758), which have recently introduced C. racemosa in their diet (Ruittton et al., 2006; Terlizzi et al., 2011).

description: In this thesis, we explore the function of a novel protein called CYRI-A through the use of biochemical, biophysical and microscopical techniques. CYRI-A belongs to the group of protein of unknown function. The previous work from our lab described its cousin protein CYRI-B to be the first negative regulator of the Scar/WAVE complex, hence regulating cell migration. Here, through the use of microscopical analysis, we unexpectedly discover the function of CYRI-A as a novel regulator of macropinocytosis. We found that CYRI-A is transiently recruited to the macropinocytic cups, at which it binds and sequesters active Rac1 and suppressing actin polymerisation. This drives the maturation and completion of the macropinocytic cups. In cancer cells, we also found that CYRI-dependent macropinocytosis is important for integrin internalisation. Thus, cells lacking CYRIs express a higher level of surface integrins, which affects its migration, adhesion, and invasion capacity. In a collaboration with the Ismail's group, we also solved the crystal structure of CYRI-B, and discovered that CYRIs are also able to dimerise with each other. This dimerisation directly competes with active Rac1 binding, adding an additional layer of regulation to CYRI. Overall, this thesis provides a careful analysis of the kinetics and localisation of CYRI-A and its novel function as a regulator of macropinocytosis.

description: No abstracts are to be cited without prior reference to the author. Marine protected areas (MPA) are figures of ecosystem management aimed at regulating the captures of species and protect them from overfishing. In many cases MPAs are a community based strategy, and their geographic delimitation has often been based on traditional ecological knowledge (TEK). New ecological methods based on statistical description of presence-only observations allow the definition of the habitat characteristics most suitable for those species. They define a suitability value for each species at each geographic location that should be maximized within the MPA area chosen for species protection. In this work we use two of these approaches (ENFA and MaDiFA) to test whether the limits of the Os Miñarzos MPA within the Seno de Corcubión (coast of Galicia, NW of Spain) fulfill these conditions based on catch data recorded by commercial vessels operating in the area. The analysis shows that the MPA includes areas where most of the commercial species analysed bear high suitability values. We conclude that habitat suitability analysis provides an alternative to TEK for the establishment of MPA, but also to continuously monitoring the evolution of species distribution, which could lead to redefinition of these protection areas in the future.
The Population of Viscosity- and Gravitational Wave-Driven Supermassive Black Hole Binaries Among Luminous AGN

description: Supermassive black hole binaries (SMBHBs) in galactic nuclei are thought to be a common by-product of major galaxy mergers. We use simple disk models for the circumbinary gas and for the binary-disk interaction to follow the orbital decay of SMBHBs with a range of total masses (M) and mass ratios (q), through physically distinct regions of the disk, until gravitational waves (GWs) take over their evolution. Prior to the GW-driven phase, the viscous decay is in the stalled "secondary-dominated" regime. SMBHBs spend a non-negligible fraction of 10^7 years at orbital periods t_var between a day and a year. A dedicated optical or X-ray survey could identify coalescing SMBHBs statistically, as a population of periodically variable quasars, whose abundance N_var is proportional to t_var^alpha, in a range of periods t_var around tens of weeks. SMBHBs with M < 10^7 M_sun, with 0.5 < alpha < 1.5, would probe the physics of viscous orbital decay, whereas the detection of a population of higher-mass binaries, with alpha=8/3, would confirm that their decay is driven by GWs. The lowest mass SMBHBs (M < 10^{5-6} M_sun) enter the GW-driven regime at short orbital periods, in the frequency band of the Laser Interferometric Space Antenna (LISA). While viscous processes are strongly sub-dominant in the last few years of coalescence, they could reduce the amplitude of any unresolved background of near-stationary LISA sources. We discuss constraints on the SMBHB population available from existing data, and the sensitivity and sky coverage requirements for a detection in future surveys. SMBHBs may also be identified from velocity shifts in their spectra; we discuss the expected abundance of SMBHBs as a function of their orbital velocity.

description: No abstracts are to be cited without prior reference to the author. Examining patterns of distribution of intertidal species is key to understand the dynamics of this highly variable habitat and has been a goal of ecological studies for decades. However, sea urchin populations are still poorly known, particularly the Atlantic populations , which may be the target of management plans due to their ecological and economic relevance. This study aims to increase the understanding of the habitat preference of P. lividus on intertidal rocky shores, an habitat which suffers strong human impacts and should be the object of regulations, including the implementation of MPAs.

description: No abstracts are to be cited without prior reference to the author. Spear fishing is currently banned from most of the world MPAs. We reviewed the literature and found that a significant number of works supporting this exclusion are overly speculative or had notable flaws in their methodology. We combined interviews to spear fishers with an historical archive of spearfishing competitions to investigate the actual effects of this activity. In Galicia (NW Spain) spear fishers caught 16% of the annual landings on the common species to the commercial fisheries and had a relevant impact on top-predators. However, their exploitation costs (-5.47 €·kg-1) was higher than those of the commercial fishery (-3.67 €·kg-1). These expenses could benefit local economies near MPAs if controlled admission is granted, particularly if spear fishers pay for access.

description: The genus Mentha has been known as culinary source of minty note. Besides, the essential oil imparts value to consumer products like confectionery, cosmetics, and pharmaceutical preparations. A simple and sensitive enantioselective gas chromatographic method is described for the quantitative analysis of terpenoid enantiomers in essential oils using different cyclodextrin coated stationary phases. Limonene, menthone, menthol, and menthyl acetate were identified as pure (-)-enantiomers whereas isomenthone, neomenthol, pulegone, and piperitone as pure (+)-enantiomers in menthol mint, and peppermint oils, respectively. The selectivity of each enantiomer was also demonstrated. A β-cyclodextrin phase with diethyl substitution provides baseline resolution for all target enantiomers with selectivity ranged from 1.004 to 1.050. Moreover, permethylated or diacetylated-β-cyclodextrin showed no selectivity for (+/-)-menthol enantiomers. The current study may facilitate the origin authentication studies of mint oils. Investigation of enantiomers involved in menthol biosynthesis revealed that only (-)-menthol is present in the essential oils of Mentha species.

description: We successfully evolved a neural network controller that produces dynamic walking in a simulated bipedal robot with compliant actuators, a difficult control problem. The evolutionary evaluation uses a detailed software simulation of a physical robot. We describe: 1) a novel theoretical method to encourage populations to evolve "around" local optima, which employs multiple demes and fitness functions of progressively increasing difficulty, and 2) the novel genetic representation of the neural controller.
