description: Diclofenac (2-(2-(2, 6-dichlorophenylamino) phenyl) acetic acid, DCF) is an emerging pollutant under the sub-class of pharmaceutical and personal care products (PPCPs). This study focused on the degradation of DCF with isolated microbial strains. The bacterial strains are considered a cost effective and eco-friendly approach for the degradation of such harmful compounds from the environment. Therefore, the experiments were started with isolation of the DCF degrading strains by the enrichment culture method. Finally, four bacterial strains; Enterococcus lactis strain DSD-1 (MN744331), Bacillus paranthracis strain DYD-1 (MN744332), Citrobacter portucalensis strain PPD-2 (MN744333) and Enterococcus faecium strain DKD-1 (MN744334) were isolated from wastewater samples. These strains degrade DCF and use it as the sole carbon and energy source. Optimized physical parameters such as temperature (32.65 °C), pH (6.36), agitation speed (82.93 rpm), and DCF concentration (40.53 mg/L) were reported through Design Expert® software. The microbial consortium experiments suggested that equal volume of all the strains was very effective. This common microbial consortium degraded almost 90% of DCF in 20 days. This was due to the synergistic activities of the strains. We have reported five intermediate metabolites (DF-1, DF-2, DF-3, DF-4, and DF-5) through the GC-MS. These further used to predict the metabolic pathway of DCF degradation.
The Teaching Coats Project : exploring the threads of our teacher identities through arts-based research
Creators: name: Poirier, Tiffany
Publisher: name: The University of British Columbia
Year: 2012

description: In a discussion of teacher identity in The Courage to Teach, Parker Palmer (2007) shares this metaphorical Hasidic tale: “We need a coat with two pockets. In one pocket there is dust, and in the other pocket there is gold. We need a coat with two pockets to remind us of who we are” (p. 113). Inspired by the powerful imagery and meaning of these words, the author of this study created “The Teaching Coats Project”, an arts-based professional development activity for teachers, which she used as the basis for this research. The Teaching Coats Project involved study participants in making their own “Teaching Coats”; these were blank white lab coats that teachers transformed with personally chosen elements such as imagery, text, memorabilia, and symbolic objects. Participants creatively expressed aspects of their professional journeys and teaching philosophies on their Teaching Coats, analyzing their choices and deepening their self-awareness through the process. Each Teaching Coat evolved and was examined as a wearable mixed media collage representing a teacher’s identity. The central questions of this study included: What are the ways teachers interpret the task to create their own Teaching Coats? And what stories do teachers share in making and discussing the meaning of their Teaching Coats? Using an arts-based narrative inquiry methodology, this research emphasized a/r/tography practices and the author’s autoethnographical account of her experiences both creating her own Teaching Coat and facilitating the project with three other teachers. The author introduced the concept of a Teaching Coat to participants during one-on-one interviews and invited them to continue creating their Teaching Coats in their own time over several months. During follow-up interviews, participants discussed the features and meanings of their Teaching Coats and shared reflections on their creative processes. The data collected included participants’ stories, written statements, interview transcripts, and photographs of Teaching Coats. The data was analyzed around a central theme of teacher identity and explored through five interrelated themes: teacher identity as a contextually embedded and co-constructed social phenomenon, teachers’ need for self-awareness, the complexity of clarifying boundaries between one’s personal and professional identity, teacher authenticity, and transformation. This study offers a rationale for how The Teaching Coats Project, as an example of an arts-based professional development opportunity, may foster teacher identity by providing a framework for independent exploration and/or participation in a practice-based community of inquiry.

description: We present the analysis of existing optical photometry and new optical spectroscopy of the candidate cataclysmic variable star OGLE-BLG504.12.201843. As was shown previously, this object has an orbital period of 0.523419 days and exhibits year-long outbursts with a mean period of 973 days. Using digitized photographic archives, we show that the earliest recorded outburst occurred in 1910. We propose that this object is a U Gem-type dwarf nova with extreme properties. The orbital variability of the system in outburst shows clear signs of an accretion disc, from which the outburst likely originates. During quiescence, the object slowly brightens by up to $0.75$ mag in the $I$ band over 600 days before the outburst and exhibits small flares with amplitude $\lesssim 0.2$ mag in the $I$ band. We interpret the gradual brightening as an increase in the luminosity and temperature of the accretion disc, which is theoretically predicted but only rarely seen in DNe. The origin of small flares remains unexplained. The spectra shows Balmer absorption lines both in quiescence and outburst, which can be associated with a bright secondary star or a cold accretion disc. During outbursts, emission lines with FWHM of about 450 km s$^{-1}$ appear, but they lack typical double-peaked profiles. We suggest that either these lines originate in the disc winds or the orbital inclination is low, the latter being consistent with constrains obtained from the orbital variability of the system. Due to its extreme properties and peculiarities, OGLE-BLG504.12.201843 is an excellent object for further follow-up studies.

description: We employ spin-polarized (SP) STM to study the spin-dependent tunneling between a magnetite (111) sample and an antiferromagnetic tip through a vacuum barrier at room temperature. Atomic scale STM images show significant magnetic contrast corresponding to variations in the local surface states induced by oxygen vacancies. The estimated variations in tunneling magnetoresistance (TMR) of 250% suggest that the spin-transport properties are significantly altered locally by the presence of surface defects.

description: We use a genetic algorithm to explore the subspace of combination and parametrization patterns spanned by a set of popular exchange and correlation functional approximations. Using the well-balanced GMTKN30 benchmark database to guide the evolutionary process, we find that the genetic algorithm is able to recover variants of several popular generalized gradient approximation functionals and hybrid functionals. For the latter class, the algorithm is able to identify a reparametrized version of the three-parameter hybrid B3PW91, which shows significantly improved performance compared to conventional versions of B3PW91. Furthermore, the possible application of this algorithm to automatically construct so-called “niche”-functionals—specially tailored to specific applications—is demonstrated.

description: Although many galaxies in the Virgo cluster are known to have lost significant amounts of HI gas, only about a dozen features are known where the HI extends significantly outside its parent galaxy. Previous numerical simulations have predicted that HI removed by ram pressure stripping should have column densities far in excess of the sensitivity limits of observational surveys. We construct a simple model to try and quantify how many streams we might expect to detect. This accounts for the expected random orientation of the streams in position and velocity space as well as the expected stream length and mass of stripped HI. Using archival data from the Arecibo Galaxy Environment Survey, we search for any streams which might previously have been missed in earlier analyses. We report the confident detection of ten streams as well as sixteen other less sure detections. We show that these well-match our analytic predictions for which galaxies should be actively losing gas, however the mass of the streams is typically far below the amount of missing HI in their parent galaxies, implying that a phase change and/or dispersal renders the gas undetectable. By estimating the orbital timescales we estimate that dissolution rates of 1-10 Msolar/yr are able to explain both the presence of a few long, massive streams and the greater number of shorter, less massive features.

description: This chapter presents a review on the latest advances in the computation of physical conditions and chemical abundances of elements present in photoionized gas H II regions and planetary nebulae). The arrival of highly sensitive spectrographs attached to large telescopes and the development of more sophisticated and detailed atomic data calculations and ionization correction factors have helped to raise the number of ionic species studied in photoionized nebulae in the last years, as well as to reduce the uncertainties in the computed abundances. Special attention will be given to the detection of very faint lines such as heavy-element recombination lines of C, N and O in H II regions and planetary nebulae, and collisionally excited lines of neutron-capture elements (Z >30) in planetary nebulae.

description: Today (year 2020), the globally recognized problem of arsenic (As) contamination of water resources and other environments at toxic levels has been reported in all of the 20 Latin American countries. The present review indicates that As is prevalent in 200 areas across these countries. Arsenic is naturally released into the environment and mobilized from geogenic sources comprising: (i) volcanic rocks and emissions, the latter being transported over thousands of kilometers from the source, (ii) metallic mineral deposits, which get exposed to human beings and livestock through drinking water or food chain, and (iii) As-rich geothermal fluids ascending from deep geothermal reservoirs contaminate freshwater sources. The challenge for mitigation is increased manifold by mining and related activities, as As from mining sites is transported by rivers over long distances and even reaches and contaminates coastal environments. The recognition of the As problem by the authorities in several countries has led to various actions for remediation, but there is a lack of long-term strategies for such interventions. Often only total As concentration is reported, while data on As sources, mobilization, speciation, mobility and pathways are lacking which is imperative for assessing quality of any water source, i.e. public and private.

description: We present the results of Raman and photoluminescence (PL) studies on epitaxial anatase phase Ti$_{1-x}$Co$_x$O$_2$ films for $x$ = 0-0.07, grown by pulsed laser deposition. The low doped system ($x$=0.01 and 0.02) shows a Curie temperature of ~700 K in the as-grown state. The Raman spectra from the doped and undoped films confirm their anatase phase. The photoluminescence spectrum is characterized by a broad emission from self-trapped excitons (STE) at 2.3 eV at temperatures below 120 K. This peak is characteristic of the anatase-phase TiO$_2$ and shows a small blueshift with increasing doping concentration. In addition to the emission from STE, the Co-doped samples show two emission lines at 2.77 eV and 2.94 eV that are absent in the undoped film indicative of a spin-flip energy.

description: Indonesia possesses a vast amount of forest resources. However, this condition has degraded and has triggered ecological and social problems. Many researches, especially forest governance researches, have been conducted in Indonesia and these have covered wide aspects of forest governance. Research findings are suspected to be neither adopted nor implemented in the policy process because there is no summary of the research findings in a simple and an easy-to-understand form. A systematic review method enables a more comprehensive search and presentation of these research findings. This paper presents a protocol map in conducting researches related to forest governance. A data extraction template with 13 keywords was used to assess articles included in the study. Based on the findings, determining keyword/s is a crucial step in conducting a systematic review.

description: Agricultural production in the face of climate change requires a climate-smart transformation and reorientation at multiple scales. Vietnam is one of the developing countries that is agriculture-based and severely affected by climate change; therefore it is crucial that the agricultural system advances toward this transformation. While climate-smart agriculture has gained a significant attention in global fora, context-specific evidence is still scarce in Vietnam. This study examines climate-smart agriculture potentials in tea production systems in the northern mountainous region of Vietnam. Since the climate-smart agriculture concept is multidimensional, which includes food security and adaptation and mitigation, an interdisciplinary analytical framework is employed in this research to assess the economic and biophysical dimensions. Enterprise budgets and representative farms (i.e., farms or households having one or more activities or enterprises) are developed for tea and alternative crops, as well as livestock production, to analyze the productivity dimension of food security. In evaluating the adaptation potential of tea production, local farmers’ perceptions and experiences of extreme weather events are combined with ERA-Interim data (1989-2013) and household survey data on income levels (reanalysis dataset taken from the European Centre for Medium-Range Weather Forecasts; ERA stands for ECMWF Reanalysis). Greenhouse gas emissions and carbon sequestration potentials are estimated through partial Carbon Footprint Life Cycle Assessment. Results show that tea production systems generate net margins, returns to capital, and family labor higher than the alternatives. Farmers, therefore, have high incentives to switch from other crops to tea production. In the face of climate change, tea has shown a strong biophysical adaptive capacity compared to other crops in the northern mountainous region. Tea production systems have a high capability for carbon storage. Evidence of strong synergies between food security and mitigation and adaptation is demonstrated for tea production systems in the northern mountainous region, and potential tradeoffs were highlighted, where relevant.

description: Land-related conflicts in Cambodia have been garnering much attention. The Cambodian government, through the Prime Minister, pledged to resolve land-related disputes, as they not only hurt the people but negatively impact on the national development agenda. Land disputes are estimated to involve 200,000 poor Cambodians. The government has been urged by international aid agencies to solve land problems to aid rural development and alleviate poverty. This paper evaluates the determinants of land conflict and its impact on land productivity, and provides recommendations on land governance in Cambodia, using an extensive 2004 nationwide household survey data consisting of 15,000 households in 600 rural and 300 urban villages. In the face of a growing landless population, primarily with loss of ownership by female-headed households, this study finds evidence that suggests other approaches for policymakers in preventing a growing landless population and land conflict prevention. It was also found out that modalities of acquisition are not a dominant cause of land conflict, while possessing land title reduces the probability of getting one's land into dispute. The analysis finds evidence of negative impact of land conflicts on farm productivity. This finding supports the hypothesis of the study and confirms the downward spiral events of conflicts that impact on farm productivity. The most involved in land-related conflicts are agricultural lands, which may signify the community’s risk for low land productivity. The numerous land grabbing incidents in Cambodia may also lead to land conflicts. There is urgent call for the Cambodian government to solve land conflicts or improve land governance not only for agricultural development, but also for Cambodians’ rights over their lands. The impetus of resolving land issues, especially in rural Cambodia, will contribute to more effective poverty reduction efforts.

description: We analyze connectivity of a heterogeneous secure sensor network that uses key predistribution to protect communications between sensors. For this network on a set $\mathcal{V}_n$ of $n$ sensors, suppose there is a pool $\mathcal{P}_n$ consisting of $P_n$ distinct keys. The $n$ sensors in $\mathcal{V}_n$ are divided into $m$ groups $\mathcal{A}_1, \mathcal{A}_2, \ldots, \mathcal{A}_m$. Each sensor $v$ is independently assigned to exactly a group according to the probability distribution with $\mathbb{P}[v \in \mathcal{A}_i]= a_i$ for $i=1,2,\ldots,m$, where $\sum_{i=1}^{m}a_i = 1$. Afterwards, each sensor in group $\mathcal{A}_i$ independently chooses $K_{i,n}$ keys uniformly at random from the key pool $\mathcal{P}_n$, where $K_{1,n} \leq K_{2,n}\leq \ldots \leq K_{m,n}$. Finally, any two sensors in $\mathcal{V}_n$ establish a secure link in between if and only if they have at least one key in common. We present critical conditions for connectivity of this heterogeneous secure sensor network. The result provides useful guidelines for the design of secure sensor networks. This paper improves the seminal work [1] (IEEE Transactions on Information Theory 2016) of Ya{ğ}an on connectivity in several aspects (omitted due to arxiv abstract's character limitation; see the paper for details).

description: Daniel John Sweeney took the King's Shilling at the age of 15, to join the Army. At the age of 27 WWI broke out so he went to fight. On 19th July 1915 Daniel started writing letters home to Ivy, a volunteer penpal, the first letter was from Machine Gun School, General Headquarters B.E.F (British Expeditionary Force) France. For 2� years Daniel continued to write to Ivy - until on 20th December 1917 he wrote from 1st Australian General Hospital, Rouen, France saying "I am slightly wounded and in hospital at the base" - with a detailed description of the events that caused his wounds, which were bad enough for Daniel to be sent back to the UK. 24th December 1917 his letter says "I have reached this beautiful place VAD hospital Rhose Hill, Uplyme, Devon". 8th May he went for discharge but did not get it spending the rest of the war in UK working with German POW. In July 1916 Daniel wrote "I expect by now you have heard of the Great Battle the date was kept secret until the very last minute, I think I am allowed to tell you and it will be a truer story than you read in the papers, I must tell you what I know and saw of this murder"�. This being the start of the Battle of the Somme. Daniel married Ivy in 1918 and they lived happily in Walthamstow, Essex until he died in 1960. The original is now in the Imperial War Museum Library - able to be read. The IWM thought they had found a "treasure trove"� when they read them.

description: Chemical compositions of four barium stars HD 26886, HD 27271, HD 50082 and HD 98839 are studied based on high resolution, high signal-to-noise Echelle spectra. Results show that all of them are disk stars. Their αand iron peak elements are similar to the solar abundances. The neutron-capture process elements are overabundant relative to the Solar. The heavy-element abundances of the strong Ba star HD 50082 are higher than those of other three mild Ba stars. Its mass is 1.32Msun (+0.28,-0.22Msun), and is consistent with the average mass of strong Ba stars (1.5Msun). For mild Ba star HD 27271 and HD 26886, the derived masses are 1.90Msun (+0.25,-0.20Msun) and 2.78Msun (+0.75,-0.78M_sun), respectively, which are consistent with the average mass of mild Ba stars. We also calculate the theoretical abundances of Ba stars by combining the AGB stars nucleosynthesis and wind accretion formation scenario of Ba binary systems. The comparisons between the observed abundance patterns of the sample stars with the theoretical results show that wind accretion scenario can explain the abundance patterns of HD 50082 and HD 27271 well, but fail to explain the abundances of HD 26886. It means that the mild Ba star HD 26886, with shorter orbital period (P<1600 d), may be formed from other scenarios. The high mass mild Ba star HD 98839, with 3.62M_sun, and with very long orbital period (P>11000 d), may be either a star with the heavy elements enriched by itself or a "true Ba" star.

description: A simulation of crop choice was performed to examine the feasibility of introducing diversified farming systems, coexisting with seasonal floods, as an alternative to triple rice cropping system in the flood-prone Mekong Delta in Vietnam. A combination of 1.78 to 1.88 ha of double rice cropping and 0.12 to 0.22 ha of upland cropping can achieve an equivalent income or profit from 2 ha of triple rice cropping. Farmers evaluated the full-dike system positively in terms of both economic aspects and living conditions. Some farmers recognized that full flood control might have worsened the natural environment and reduced soil fertility resulting in declining rice yields. To establish a smart flood control system as an adaptation strategy against expected climate change, the following measures must be undertaken: (1) sensitize farmers to the increasing climatic risk in the near future and long-term adverse effects of intensive triple rice cropping; (2) offer alternative environmentally sound and economically profitable farming systems; and (3) develop institutional design for well-coordinated gate and pumping operations both at dike units and in canal network systems.

description: Bevil Geach was born in 1887 in Polperro, Cornwall. He joined the Navy on 30th May 1904, when WWI broke out he was a Petty Officer. He joined "Jupiter" on 2nd August 1914 a majestic-class battle ship. In October 1914 it was a Coastal Defence & Tyne Guard Ship. On 4th February 1915 "Jupiter"�was told to proceed to Archangel town in North Russia as a supply ship had broken down carrying provisions for town. The crew were not told the destination as it was Top Secret. They had to sail through enemy lines with no convoy. On 6th February 1915 a hurricane caused much damage; 24 hours later the storm abated. On 12th February 1915 "Jupiter" got stuck in ice, the crew were told to wrap up warm, put 12lb shells in their pockets and run from side to side of the ship to free her. On 27th March 1915 they eventually found the Russian ship the "Thracia"� and started to tow her, nearing Archangel the ice was too thick and water too shallow so they had to unload provisions by pulley system. This exercise was record breaking as it saved the people of the town's lives. Their fuel & provisions were almost gone. "Jupiter"� was a 20 year old battle ship not equipped for these conditions; the bow was constantly holed by ice. The crew was awarded a medal by Czar Nicholas; it had to get sanctioned by the King to be worn.
Black hole formation in relativistic Oscillaton collisions

description: We investigate the physics of black hole formation from the head-on collisions of boosted equal mass Oscillatons (OS) in full numerical relativity, for both the cases where the OS have equal phases or are maximally off-phase (anti-phase). While unboosted OS collisions will form a BH as long as their initial compactness $\mathcal{C}\equiv GM/R$ is above a numerically determined critical value $\mathcal{C}>0.035$, we find that imparting a small initial boost counter-intuitively \emph{prevents} the formation of black holes even if $\mathcal{C}> 0.035$. If the boost is further increased, at very high boosts $γ>1/12\mathcal{C}$, BH formation occurs as predicted by the hoop conjecture. These two limits combine to form a "stability band" where collisions result in either the OS "passing through" (equal phase) or "bouncing back" (anti-phase), with a critical point occurring around ${\cal C}\approx 0.07$. We argue that the existence of this stability band can be explained by the competition between the free fall and the interaction timescales of the collision.

description: We perform 3D hydrodynamics simulations of disc-disc stellar flybys with on-the-fly Monte Carlo radiative transfer. We show that pre-existing circumstellar discs around both stars result in fast rising ($\sim$yrs) outbursts lasting 2-5 times longer than for a star-disc flyby. The perturber always goes into outburst ($\dot{M}>10^{-5}~{\rm M_{\odot}~ yr^{-1}}$). Whereas we find that the primary goes into a decades long outburst only when the flyby is retrograde to the circumprimary disc rotation. High accretion rates during the outburst are triggered by angular momentum cancellation in misaligned material generated by the encounter. A large fraction of accreted material is alien.

description: The raging debate on organic versus conventional agriculture, and with regard to the aspect of productivity in particular, is far from conclusive. In this analysis, we explore the productivity comparison further through the evaluation of a common production technology used in 74 countries around the world, over the period 2005 to 2014. We found conventional agriculture to be more productive than organic agriculture. Whilst productivity of conventional agriculture is exponentially rising, that of organic is declining, although it has a quadratic growth path. For every hectare of conventional agricultural land given up, only 0.54 hectares of organic land area is substituted. Based on an elasticity of substitution of 0.36, the isoquant is relatively vertical; therefore, much more conventional lands need to be substituted with an organic land area. Research into new and improved fertilising and pest control methods is essential as positive developments there would have a significant impact on organic land productivity.

description: This study analyses the relationship among carbon dioxide emissions, energy consumption, agricultural labour productivity, agricultural land productivity and agricultural raw material exports using a time series for the period 1960-2015. In this article, some theoretical hypotheses are formulated, aiming to explain the bidirectional causality between agricultural productivity and climate change. These hypotheses are tested by using Vector Autoregression (VAR), Granger causality and Vector Error Correction Models (VECM). Results confirm relevant theoretical hypotheses between agricultural productivity and climate change and show that the variables used are stationary. Agricultural labour and land productivity as well as agricultural raw material exports are positively related to CO2 emissions, meaning that these variables stimulate environmental pollution. Empirical results presented in the paper might be of interest to the academic community and also to policymakers.

description: A sample of radio-loud active galactic nuclei (AGN) at 2cm is studied to test the isotropic distribution of radio sources in the sky and their uniform distribution in space. The sample is complete flux-density limits of 1.5Jy for positive declinations and 2Jy for declinations between 0 and -20 degrees. The active galactic nuclei sample comprises of 133 members. Application of the two-dimensional Kolmogorov-Smirnov test shows that there is no significant deviation from the isotropic distribution in the sky, while the generalised V/Vm test shows that the space distribution of AGN is not uniform at high confidence level (99.9%). This is indicative of a strong positive evolution of AGN with cosmic epoch implying that AGN (or jet activity phenomena) were more populous at high redshifts. It is shown that the evolution depends strongly on luminosity: low-luminosity QSOs show a strong positive evolution, while high-luminosity counterparts do not seem to show any evolution with cosmic epoch.

Beef cattle futures markets: Is it possible in Uruguay?

description: In 1993 there was an attempt to develop a futures market for beef cattle in Uruguay. The experience did not fulfill the expectations created around this market and after six months of trading, it closed its activities. The possible reasons that inhibited its development were examined in this paper. It is possible that all the necessary conditions for success can not be given at this moment. Perhaps the low volume traded in the futures market was derived from structural conditions that are inherent in small economies. Maybe there was a failure in creating the minimal conditions that could attract enough hedgers and speculators capable of supporting the market. Determining why the experience failed would be very to understand the underlying mechanisms of this instrument, in a country with a small economy and without any tradition in its use.

Growing Surfaces with Anomalous Diffusion - Results for the Fractal Kardar-Parisi-Zhang Equation

description: In this paper I study a model for a growing surface in the presence of anomalous diffusion, also known as the Fractal Kardar-Parisi-Zhang equation (FKPZ). This equation includes a fractional Laplacian that accounts for the possibility that surface transport is caused by a hopping mechanism of a Levy flight. I show that for a specific choice of parameters of the FKPZ equation, the equation can be solved exactly in one dimension, so that all the critical exponents, which describe the surface that grows under FKPZ, can be derived for that case. Afterwards, I use a Self-Consistent Expansion (SCE) to predict the critical exponents for the FKPZ model for any choice of the parameters and any spatial dimension. It is then verified that the results obtained using SCE recover the exact result in one dimension. At the end a simple picture for the behavior of the Fractal KPZ equation is suggested, and the upper critical dimension of this model is discussed.

description: In order to understand the global importance of foods with Geographical Indications (GIs), it is essential to get an overview of the market size for such products. In spite of the relative importance of GI policy in EU trade agreements, there are only very limited data available on the actual market size for GI labelled products. Against this background this paper collects all the available data that provides estimates of the market size for GI foods, analysing the available datasets and reports of the European Commission and conducting a systematic literature review on the academic papers related to this topic. Based on the results we can underline the high level of concentration of GI products in terms of origin and product category. The most important GI market is the domestic market of the European Union even though the share of GI production is only a minor part of total agri-food output. On the other hand, GI products with both significant market size (domestic and export) and remarkable market share also exist, but these are a small set of all registered GI products and are concentrated in only a few countries.
