description: Lake Naivasha and Lake Oloiden merged leading to the formation of an estuary. This occurrence may affect the water quality and phytoplankton. A study was conducted with the objective: to investigate seasonal changes in the water quality parameters and their effect on phytoplankton. Depth and secchi depth were measured while some water quality parameters were measured in situ using YSI Multiparameter meter and water samples were collected for laboratory analysis of chlorophyll-a, phosphates, nitrates and total suspended solids. Phytoplankton sample was collected; identification and counting were done under a compound microscope. The nutrients, depth, secchi depth, temperature, dissolved oxygen, salinity, conductivity, total dissolved solids and pH varied monthly. All the water quality parameters positively correlated with Chlorophyceae in Lakes Naivasha and Oloiden except dissolved oxygen, chlorophyll-a, depth and secchi depth that negatively correlated. There were seasonal changes in all the water quality parameters in Lakes Naivasha and Oloiden except the total suspended solids whose effects were in Midlake There were seasonal changes in all the water quality parameters in Lakes Naivasha and Oloiden except the total suspended solids whose effects were only in Midlake and Oloiden ST2. Euglenophyceae, Bacillariophyceae were not affected by water quality except the depth while the other families had varied effects from water quality in Lake Naivasha. All Lake Oloiden's phytoplankton families had varied effects from the water quality. Thus, the prevailing water quality affect phytoplankton

description: In a recent work [Proc. Natl. Acad. Sci. USA 108, 3838 (2011)], Schneider et al. proposed a new measure for network robustness and investigated optimal networks with respect to this quantity. For networks with a power-law degree distribution, the optimized networks have an onion structure-high-degree vertices forming a core with radially decreasing degrees and an over-representation of edges within the same radial layer. In this paper we relate the onion structure to graphs with good expander properties (another characterization of robust network) and argue that networks of skewed degree distributions with large spectral gaps (and thus good expander properties) are typically onion structured. Furthermore, we propose a generative algorithm producing synthetic scale-free networks with onion structure, circumventing the optimization procedure of Schneider et al. We validate the robustness of our generated networks against malicious attacks and random removals.

description: One of the most relevant manifestations of the Beresinskii-Kosterlitz-Thouless transition occurs in quasi-two-dimensional superconducting systems. The experimental advances made in the last decade in the investigation of superconducting phenomena in low-dimensional correlated electronic systems raised new questions on the nature of the BKT transitions in real materials. A general issue concerns the possible limitations of theoretical predictions based on the XY model, that was studied as a paradigmatic example in the original formulation. Here we review the work we have done in revisiting the nature of the BKT transition within the general framework provided by the mapping into the sine-Gordon model. While this mapping was already known since long, we recently emphasized the advantages on such an approach to account for new variables in the BKT physics. One such variable is the energy needed to create the core of the vortex, that is fixed within the XY model, while it attains substantially different values in real materials. This has interesting observable consequences, especially in the case when additional relevant perturbations are present, as a coupling between stacked two-dimensional superconducting layers or a finite magnetic field.

description: Recent low-temperature scanning-tunneling microscopy experiments [T. Kumagai et al., Phys. Rev. B 79, 035423 (2009)] observed the vibrationally induced flip motion of a hydroxyl dimer (OD)2 on Cu(110). We propose a model to describe two-level fluctuations and current-voltage characteristics of nanoscale systems which undergo vibrationally induced switching. The parameters of the model are based on comprehensive density-functional calculations of the system's vibrational properties. For the dimer (OD)2 the calculated population of the high and low conductance states, the I-V, dI/dV, and d2I/dV2 curves are in good agreement with the experimental results and underlines the different roles played by the free and shared OD stretch modes of the dimer.

description: This text discusses the end of the illusion of tourism as a socio-spatial practice for achieving sustainable development. Based on specific cases of urban touristification processes which have occurred in some of the territories situated in Pernambuco State (Brazil), this text states that, although tourism has not promoted, per se, sustainable development, it is an important socio-spatial practice for the places where it occurs. This central argument has been based on a review of the literature on the subject, as well as some results of field surveys conducted at different times and in different places of tourism mainly in Recife, the capital of the State of Pernambuco.

description: The 2023 coronial inquest findings into the death of Aboriginal woman, Ms Veronica Nelson, in a Victorian prison represents a high-water mark for the relevance and application of the Victorian Charter of Human Rights and Responsibilities Act 2006 to inquests into deaths in custody. The reliance on the Victorian Charter in the inquest was particularly significant because of the detailed findings and recommendations, directed at a wide variety of criminal justice system agencies, intended to prevent future deaths in custody. The outcome of the inquest clearly demonstrates that Human Rights Acts can enhance the preventive function of coroners in Australia.

Demand has been tremendous, totaling over 3600 evening EI sessions in the Fall of 2010. Meeting this demand with only four (now five) full time faculty has been challenging. EI Videos have been produced to help serve cadets in need of well-modeled solutions to homework-type problems. These videos have been warmly received, being viewed over 14,000 times in Fall 2010 and probably contributing to a significant increase in the first attempt success rate on the Algebra Fundamental Skills Exam in Calculus 1. EI Video production is being extended to better support Calculus 2, Calculus 3, and Physics 1.

description: The Hubble Deep Field (HDF) is a region in the sky that provides one of the deepest multi-wavelength views of the distant universe and has led to the detection of thousands of galaxies seen throughout cosmic time. An early map of the HDF at a wavelength of 850 microns that is sensitive to dust emission powered by star formation revealed the brightest source in the field, dubbed HDF850.1. For more than a decade, this source remained elusive and, despite significant efforts, no counterpart at shorter wavelengths, and thus no redshift, size or mass, could be identified. Here we report, using a millimeter wave molecular line scan, an unambiguous redshift determination for HDF850.1 of z=5.183. This places HDF850.1 in a galaxy overdensity at z~5.2 in the HDF, corresponding to a cosmic age of only 1.1 Gyr after the Big Bang. This redshift is significantly higher than earlier estimates and higher than most of the >100 sub-millimeter bright galaxies identified to date. The source has a star formation rate of 850 M_sun/yr and is spatially resolved on scales of 5 kpc, with an implied dynamical mass of ~1.3x10^11 M_sun, a significant fraction of which is present in the form of molecular gas. Despite our accurate redshift and position, a counterpart arising from starlight remains elusive.

description: Rare-earth ions in dielectric crystals are interesting candidates for storing quantum states of photons. A limiting factor on the optical density and thus the conversion efficiency is the distortion introduced in the crystal by doping elements of one type into a crystal matrix of another type. Here, we investigate the system Pr3+:La2(WO4)3, where the similarity of the ionic radii of Pr and La minimizes distortions due to doping. We characterize the praseodymium hyperfine interaction of the ground state (3H4) and one excited state (1D2) and determine the spin Hamiltonian parameters by numerical analysis of Raman-heterodyne spectra, which were collected for a range of static external magnetic field strengths and orientations. On the basis of a crystal field analysis, we discuss the physical origin of the experimentally determined quadrupole and Zeeman tensor characteristics. We show the potential for quantum memory applications by measuring the spin coherence lifetime in a magnetic field that is chosen such that additional magnetic fields do not shift the transition frequency in first order. Experimental results demonstrate a spin coherence lifetime of 158 ms - almost three orders of magnitude longer than in zero field.

Subjects: Cultural Tourism; Ethno Tourism; Heritage; Vibrant Community; Creative Tourism

description: Tourism is a powerful economic development tool which creates jobs, provides new business opportunities and strengthens local economies. Starting with the local culture and already existing communities and geographies, tourism developments can enhance the interesting and unique aspects of a location. Using local traditions, beliefs, and resources reinforces the cultural heritage of a location, making these new areas thriving cultural hubs. These communities hold the social values of the residents that connect them to their culture and history, and they also promote the education of these values, which attracts tourists and visitors who are interested in understanding local culture. This increased flow of people boosts local businesses, which in turn supports the community by building a strong economic foundation, allowing the local culture to flourish and create an even more vibrant community. It is now well admired worldwide that development and management of tourism at any destination or place, requires a multi-dimensional approach (strengthen the institutional capacity, engage with multiple stakeholders, establish appropriate protocols and systems). When cultural heritage tourism development is done right, it also helps to protect our nation’s natural and cultural treasures and improve the quality of life for residents and visitors. Linking tourism with heritage and culture can do more for local economies than promoting them separately. This article explores the ethnic heritage and emphasizes on the holistic tourism development approach after considering the various heritage tourism resources available in the state.

La luce e i termini ad essa correlati costituiscono forse il campo semantico più prolifico nella costruzione simbolica dell’immaginario umano e si configura come un archetipo fondamentale, a cui la lingua attinge fin dagli albori della letteratura universale. Nel suo libro Come un raggio nell’acqua. Dante e la relazione con l’altro, La Porta compie una lettura originale del Paradiso di Dante, percorrendo un viaggio, che a tratti può apparire temerario ma sempre brillantemente giustificato, attraverso le immagini metaforiche che attingono al campo semantico della luce e che innervano la Terza Cantica, con uno sguardo attento a ciò che possono comunicare al nostro mondo post-contemporaneo.

description: The Tourism Satellite Account (TSA) is a method for estimation of the role of tourism in the economy based on the collection and processing of large numbers of statistic data. TSA can be created on a national or regional levels and reflect aggregates which connect with the planning and development of tourism. This approach can improve the overall quality and consistency of the system of national accounts of a country.  The Caribbean region, quite like other areas of the world, have had some challenges in creating the TSA. The main aim of this paper is to examine the concept of the Tourism Satellite Account and its potential benefits for the Eastern Caribbean Islands.

Benchmarking the UNWTO Practical Tips for the Global Traveller: An Islamic Preview

Subjects: Islam; Tourism; Code of ethics; Travellers' behavior; Social impacts

description: Despite the great emphasis on tourism as a worldwide leading economic sector, tourism basically remains as a social activity which has been typically associated with numerous positive and negative impacts.  In this context, it could be understood why the UNWTO tended in 1999 to release its Code of Ethics for Tourism and to follow that by issuing the UNWTO Practical Tips for the Global Traveller in 2005 aiming mainly to set up a frame of mutual understanding and respect between tourists and their hosting societies in tourism destinations. On the other hand, almost all the known religions have a substantial component of social ethics, values and regulations. Accordingly, this paper aims to benchmark the UNWTO Practical Tips for the Global Traveller (PTGT) against the principles of Islam as one of the world’s main religions. In this regard, content analysis of assorted, relevant documents in association with semi-structured interviews were employed as research methods, which resulted in identifying similarities and dissimilarities between the two models, and revealed the need for reforming some of the items of the PTGT as well as adding few new principles. The research findings could be of significance for several stakeholders including PTGT formers, sociologists, as well as tourism decision makers.

Low-mass suppression of the satellite luminosity function due to the supersonic baryon--cold-dark-matter relative velocity

description: We study the effect of the supersonic baryon--CDM flow, which has recently been shown to have a large effect on structure formation during the dark ages 10 ~ 10, a large effect results on the stellar luminosity function before reionization. As halos of these masses are believed to have very little star formation after reionization due to the effects of photo-heating by the ultraviolet background, this effect persists to the present day. We calculate that the number of low-mass 10^6 < M_{halo} / M_solar < 10^8 halos that host luminous satellite galaxies today is typically suppressed by 50 percent, with values ranging up to 90 percent in regions where the initial supersonic velocity is high. We show that this previously-ignored cosmological effect resolves most of the tension between the observed and predicted number of low-mass satellites in the Milky Way, obviating the need for any other mass-dependent star-formation suppression before reionization.

Sustainable Coastal Destination Development: Fostering Green Practices of Restaurateurs

Year: 2015
Subjects: Coastal tourism; Hospitality; Sustainability; Restaurants; Vrouwenpolder

description: Coastal tourism destinations are reinventing themselves, concentrating on product improvement and image enhancement. Reinventing sustainably is key and restaurants are an important factor. Research upon the processes of change in the industry seems to be fragmented and undefined in its conclusions. Knowledge is lacking on what specifically drives innovation in the hospitality industry. Since restaurants seem to be focusing more than ever on implementing green strategies, incorporating sustainability into restaurant practices is not an unexplored area.
However, the how and why it is incorporated or not, can be different per restaurant. The objective of this study is to identify possibilities of change in restaurateur practices, which can lead to interventions that will foster sustainable destination development in Vrouwenpolder; a coastal destination within the Netherlands. For the identification of interventions that could advance the sustainability enacted in restaurateur practices, a qualitative research was conducted.
Practices of restaurateurs in Vrouwenpolder are identified and compared to perceived-to-be ideal practices. Analysis of data collection draws on practice theory, and resulted into recommendations for advancing the sustainability enacted in restaurateur practices. It seems to be that primarily the meaning within a practice is decisive in whether sustainability is integrated or not.

description: Superconductivity in the Bechgaard salts series of quasi-one-dimensional organic conductors occurs on the verge of spin-density-wave ordering when hydrostatic pressure is applied. The sequence of instabilities is intimately connected to normal state anomalies in various quantities like the temperature dependence of electrical transport and nuclear spin-lattice relaxation rate. We discuss how such a connection takes its origin in the interference between the different pairing mechanisms responsible for antiferromagnetism and superconductivity, a duo that can be comprehended in terms of a weak coupling renormalization group theory. The recent developments along this line of though are presented in relation to experiments.

description: We recently identified several emission bands in the Spitzer-IRS spectrum of the unusual planetary nebula Tc 1 with the infrared active vibrational modes of the neutral fullerene species C60 and C70. Since then, the fullerene bands have been detected in a variety of sources representing circumstellar and interstellar environments. Abundance estimates suggest that C60 represents ~0.1%-1.5% of the available carbon in those sources. The observed relative band intensities in various sources are not fully compatible with single-photon heating and fluorescent cooling, and are better reproduced by a thermal distribution at least in some sources. The observational data suggests that fullerenes form in the circumstellar environments of evolved stars, and survive in the interstellar medium. Precisely how they form is still a matter of debate.

Finally I describe a new type of exponentiated flux operator, and its application to Chern-Simons theory and black holes.

description: A reliable network infrastructure must be able to sustain traffic flows, even when a failure occurs and changes the network topology. During the occurrence of a failure, routing protocols, like OSPF, take from hundreds of milliseconds to various seconds in order to converge. During this convergence period, packets might traverse a longer path or even a loop. An even worse transient behaviour is that packets are dropped even though destinations are reachable. In this context, this paper describes a proactive fast rerouting approach, named Fast Emergency Paths Schema (FEP-S), to overcome problems originating from transient link failures in OSPF routing. Extensive experiments were done using several network topologies with different dimensionality degrees. Results show that the recovery paths, obtained by FEPS, are shorter than those from other rerouting approaches and can improve the network reliability by reducing the packet loss rate during the routing protocols convergence caused by a failure.

description: Bolometric luminosities and Eddington ratios of both X-ray selected broad-line (Type-1) and narrow-line (Type-2) AGN from the XMM-Newton survey in the COSMOS field are presented. The sample is composed by 929 AGN (382 Type-1 AGN and 547 Type-2 AGN) and it covers a wide range of redshifts, X-ray luminosities and absorbing column densities. About 65% of the sources are spectroscopically identified as either Type-1 or Type-2 AGN (83% and 52% respectively), while accurate photometric redshifts are available for the rest of the sample. The study of such a large sample of X-ray selected AGN with a high quality multi-wavelength coverage from the far-infrared (now with the inclusion of Herschel data at 100 micron and 160 micron) to the optical-UV allows us to obtain accurate estimates of bolometric luminosities, bolometric corrections and Eddington ratios. The kbol-Lbol relations derived in the present work are calibrated for the first time against a sizable AGN sample, and rely on observed redshifts, X-ray luminosities and column density distributions. We find that kbol is significantly lower at high Lbol with respect to previous estimates by Marconi et al. (2004) and Hopkins et al. (2007). Black hole masses and Eddington ratios are available for 170 Type-1 AGN, while black hole masses for Type-2 AGN are computed for 481 objects using the black hole mass-stellar mass relation and the morphological information. We confirm a trend between kbol and lambda_Edd, with lower hard X-ray bolometric corrections at lower Eddington ratios for both Type-1 and Type-2 AGN. We find that, on average, Eddington ratio increases with redshift for all Types of AGN at any given Mbh, while no clear evolution with redshift is seen at any given Lbol.

description: Stellar mass loss rates are an important input ingredient for stellar evolution models since they determine stellar evolution parameters such as stellar spin-down and increase in stellar luminosity through the lifetime of a star. Due to the lack of direct observations of stellar winds from Sun-like stars stellar X-ray luminosity and stellar level of activity are commonly used as a proxy for estimating stellar mass loss rates. However, such an intuitive activity --- mass loss rate relation is not well defined. In this paper, I study the mass loss rate of the Sun as a function of its activity level. I compare in-situ solar wind measurements with the solar activity level represented by the solar X-ray flux. I find no clear dependency of the solar mass flux on solar X-ray flux. Instead, the solar mass loss rate is scattered around an average value of $2\cdot10^{-14}\;M_\odot\;yr^{-1}$. This independency of the mass loss rate on level of activity can be explained by the fact that the activity level is governed by the large modulations in the solar close magnetic flux, while the mass loss rate is governed by the rather constant open magnetic flux. I derive a simple expression for stellar mass loss rates as a function of the stellar ambient weak magnetic field, the stellar radius, the stellar escape velocity, and the average height of the Alfvén surface. This expression predicts stellar mass loss rates of $10^{-15}-10^{-12}\;M_\odot\;yr^{-1}$ for Sun-like stars.

description: We present the latitude-normalized radial velocity (vb) distribution of 3318 subsolar metallicity, V<13.5 stars from the Grid Giant Star Survey (GGSS) in Southern Hemisphere fields. The sample includes giants mostly within ~5 kpc from the Galactic disks and halo. The nearby halo is found to (1) exhibit significant kinematical substructure, and (2) be prominently represented by several velocity coherent structures, including a very retrograde "cloud" of stars at l~285 deg and extended, retrograde "streams" visible as relatively tight l-vb sequences. One sequence in the fourth Galactic quadrant lies within the l-vb space expected to contain tidal debris from the "star cluster" wCentauri. Not only does wCen lie precisely in this l-vb sequence, but the positions and vb of member stars match those of N-body simulations of tidally disrupting dwarf galaxies on orbits ending with wCen's current position and space motion. But the ultimate proof that we have very likely found extended parts of the wCen tidal stream comes from echelle spectroscopy of a subsample of the stars that reveals a very particular chemical abundance signature known to occur only in wCen. The newly discovered wCen debris accounts for almost all fourth Galactic quadrant retrograde stars in the southern GGSS, which suggests wCen is a dominant contributor of retrograde giant stars in the inner Galaxy.

description: We report the discovery of a brown dwarf companion to the young M dwarf 1RXS J235133.3+312720 as part of a high contrast imaging search for planets around nearby young low-mass stars with Keck-II/NIRC2 and Subaru/HiCIAO. The 2.4" (~120 AU) pair is confirmed to be comoving from two epochs of high resolution imaging. Follow-up low- and moderate-resolution near-infrared spectroscopy of 1RXS J2351+3127 B with IRTF/SpeX and Keck-II/OSIRIS reveals a spectral type of L0$^{+2}_{-1}$. The M2 primary star 1RXS J2351+3127 A exhibits X-ray and UV activity levels comparable to young moving group members with ages of ~10-100 Myr. UVW kinematics based the measured radial velocity of the primary and the system's photometric distance (50 +/- 10 pc) indicate it is likely a member of the ~50-150 Myr AB Dor moving group. The near-infrared spectrum of 1RXS J2351+3127 B does not exhibit obvious signs of youth, but its H-band morphology shows subtle hints of intermediate surface gravity. The spectrum is also an excellent match to the ~200 Myr M9 brown dwarf LP 944-20. Assuming an age of 50-150 Myr, evolutionary models imply a mass of 32 +/- 6 Mjup for the companion, making 1RXS J2351+3127 B the second lowest-mass member of the AB Dor moving group after the L4 companion CD-35 2722 B and one of the few benchmark brown dwarfs known at young ages.

description: For decades, the hemagglutination-inhibition (HI) assay has been used in epidemiological and basic biological studies of influenza viruses. The mechanistic basis of the assay results (called titers) is not well understood. The first part of this document describes a biophysical model of HI that illuminates the mechanistic basis of and provides the theoretical motivation for new ways of interpreting titers. The biophysical model is applicable to other serological assays; this fact is illustrated using the neutralization assay. The second part of the document describes some new ways of interpreting titers, which involve, among other methods, singular value decomposition and probabilistic multidimensional scaling. The third part of the document discusses biological and mathematical issues related to the determination of the effective dimensionality of titers, and describes an algorithm for recovering unavailable titers.

description: The Ghanzi-Chobe Belt in Botswana’s portion of the Kalahari Copper Belt is home to Cu-Ag deposits. However, due to a lack of sufficient radiometric data, the origin of these deposits has remained a source of contention. We used sericite 40Ar/39Ar and in-situ biotite LA-ICP-MS Rb-Sr geochronology in samples from two mineralized zones of the Ghanzi-Chobe Belt to better bracket mineralization timing and then elaborate on the genesis of Cu-Ag mineralization in this portion of the Kalahari Copper Belt. Radiometric data suggest multiple mineralization events of Cryogenian (ca. 670 Ma) and Ediacaran (ca. 588 and ca. 566 Ma) ages and highlight mineralization events that were previously unknown. The ca. 670 Ma (sericite 40Ar/39Ar) event coincided with the final break-up of the Rodinian supercontinent. The 588.3 ± 0.2 Ma (sericite 40Ar/39Ar) and 565.6 ± 6.5 Ma (biotite Rb-Sr) fluid pulse events correspond to syn-orogenic and syn-metamorphic Cu-Ag mineralization episodes, which occurred over a 72-million-year period (considering the previously reported molybdenite Re/Os age of 515.9 ± 2 Ma) that overlaps with the window time frame of basin inversion and metamorphism in the Kalahari Copper Belt. The ca. 670 Ma event, as well as the extended age range of syn-orogenic Cu-Ag mineralization, contributed to the refinement of the genetic model of sedimentary rock-hosted Cu-Ag mineralization in the Ghanzi-Chobe Belt and the Kalahari Copper Belt. Our radiometric data shed new light on Cu-Ag mineralization in the Ghanzi-Chobe Belt and the Kalahari Copper Belt. As the identification of numerous pulses of mineralization is an important factor in the formation of giant-to-supergiant sedimentary rock-hosted Cu-Ag deposits, the possibility of such deposits occurring within the Kalahari Copper Belt cannot be discounted. In the Kalahari Copper Belt, Damara Belt, and Central African Copper Belt, the Pan-African deformation and Gondwana assembly period were critical metallogenic epochs.
