An Investigation into the Release of Chemical Oxygen Demand in Organic Filter Media

To improve the nitrogen reduction capability of stormwater treatment systems subjected to intermittent saturation, organic materials are often added as filter media. However, these materials can be an additional source of organic carbon and increase the chemical oxygen demand (COD) in the outflow. In this study, different types of organic filter media were subjected to a batch leaching test to observe and quantify the release of COD. Results reveal that the initial pH of the tap water used for soaking which is 7.5-7.7 is conducive to the release of organics from the media to the leachate. The highest amount of COD released was observed in yard clippings and woodchip followed by compost and bark mulch. The leaching of organics also increased as the size of the media decreases due to higher surface area per volume. In addition, empirical regression analysis predicted that COD from these organic media will be exhausted from the material in 3-5 months to up to 26 months depending on the type of media. The results of this study can serve as a guide in estimating the potential release of COD in organic media in order to ensure their safe application in stormwater treatment facilities.
A note on a prototype system for simple computer-assisted matching of individually identified southern right whales, Eubalaena australis

A system using computer assistance in the matching of the callosity patterns of individual southern right whales is described. When provided with a digitised representation of an individual whale’s callosity pattern, the prototype system produces a hierarchical output of the most similar patterns in the database with relatively high accuracy. A trial database of binary images of the callosity patterns of 165 individually identified southern right whales was created. A further two replicates each of nine different individual whales within the trial database, were then created by two different operators, producing a test set of 18 images. A software program, utilising a pattern recognition algorithm and incorporating a mouse driven user interface, was developed so that when provided with a binary bitmap of an individual whale from the test set, the program compares it against a trial database of previously saved bitmaps and produces a hierarchical output of the most similar whales, or nearest ‘matches’. For 15 of the 18 test images (83%), the system returned the correct whale as the top match out of the 165 in the trial database. For the remaining three test images the correct whale was the second, sixth and sixteenth ranked whale in the trial database containing 165 whales. The program was successful in reducing the number of individuals required for manual comparison to a small percentage of the total catalogue, with a high degree of accuracy, and with a significant associated time saving. It is envisaged that the final matching will continue to be done visually by an experienced operator using the original photographs. Further refinement of the system with the aim of streamlining and simplifying the input process and incorporating partial pattern recognition is
PHYSICS AND CHEMISTRY OF SOLID STATE

The temperature dependences of the optical absorption edges of Zn doped GaAs semiconductor crystals have been measured from 300 to 560 K. The temperature dependence of the optical absorption in the Urbach edges is adequately reproduced by a Bose-Einstein model. Analysis of experimental results gave us the opportunity to offer an explicit function of two arguments (photon energy and temperature) for the absorption coefficient of doped crystals in the Urbach edge region.
ATMOSPHERIC BROWN CLOUDS: HEALTH, CLIMATE AND AGRICULTURE IMPACTS

Aerosols or atmospheric particles are either in solid form, such as dust or sea salt, or in liquid form, such as sulfates, nitrates or organics dissolved in water. Nature produces aerosols in the form of sea salt, mineral dust, sulfates and nitrates. Human activities either emit gaseous precursors, such as SO2 and NOx which get converted into particles through chemical processes, or directly emit particles such as soot, which is a mixture of elemental carbon and organics. The concentrations of natural aerosols in pristine air are typically around 100 to 1000 particles per cc in continental air and about 100 to 500 per cc in marine air. It is now increasingly difficult, if not impossible, to find such pristine air. In most regions of the northern hemisphere, including over the oceans, the concentrations are larger by factors ranging from two to ten. Humans add particles to the air by a variety of actions, including the burning of biofuels and fossil fuels for cooking purposes, the consumption of fossil fuel for energy, the clearing of forests, and land use modification, to name a few.

Frontal fibrosing alopecia: state of the art and future directions

Frontal fibrosing alopecia (FFA) is a primary lymphocytic cicatricial alopecia, characterized by recession of frontotemporal hairline with frequent involvement of eyebrows and affecting occasionally other body areas. Entitled an emerging epidemic, due to its rising incidence, FFA etiology remains unclear without proven effective therapies. This study reviews relevant publications on FFA, regarding pathogenesis, clinical findings, histology along with treatment and prognosis. A bibliographic search was conducted in the main international databases, using the term ‘FFA’. Guidelines, observational studies, randomized controlled trials, reviews, systematic reviews and meta-analysis regardless of publication date, presented in English, Portuguese or Spanish, were included in this review. 50 publications were fully analysed. The majority of FFA cases were observed in postmenopausal women, although both men and women from younger ages can be victims. From an etiological point of view, immune-mediated hypothesis is widely spread, as stem cells localized in the bulge region of the follicle are destroyed by an inflammatory infiltrate. However, environmental factors raised interest, since sunscreen use was related to a bigger incidence of FFA. Three clinical patterns have been described. Yet the failure to use standardized assessment methods in addition to the absence of prospective studies evaluating available therapies, do not concede comparable data. Spontaneous stabilization of disease can occur, but regrowth was only seen in scarce cases. Outcomes from randomized controlled trials and prospective studies are missing to draw further understanding of FFA.
Enzyme activities of urban soils under different land use in the Shenzhen city, China

Urbanization has drastically changed soil properties, and an assessment of these changes is essential for soil management and soil health. The activities of urease, acid phosphatase, invertase and catalase, soil organic matter, pH, electrical conductivity (EC) and clay (< 0.01 mm) content of urban soils under two land-uses in the central built-up area of the Shenzhen city were investigated, and multivariate analysis was used to study the relationship between soil enzymes and soil physical-chemical properties. The results showed that invertase activity in roadside soil was significantly higher than that in urban park soil, whereas catalase activity was significantly higher in urban park soil. Soil organic matter had significant positive correlation with activities of invertase, urease and acid phosphatase but not with catalase. Soil pH had a significant negative direct effect on urease and acid phosphatase activity, but the effect was counteracted by positive indirect effect of soil organic matter. Soil EC had a positive direct effect on activities of catalase and there was a significant correlation between soil EC and soil catalase activities. Soil organic matter, soil pH and EC were the major factors influencing activities of soil enzymes.

Teaching and Learning Occupation in Occupational Therapy Education: A Qualitative Evidence Synthesis

Occupation is the core focus of the occupational therapy profession and is a complex concept for students to know and understand. The aim of this review was to understand how teaching and learning occupation has been represented by educators and students across qualitative studies in occupational therapy education. A qualitative evidence synthesis was conducted which included searching four databases; CINAHL, Medline, Scopus, and Embase. Research articles were screened using inclusion and exclusion criteria by two reviewers. The search resulted in 328 records being identified, with 13 articles included. The methodological quality of included articles was assessed using the Critical Appraisal Skills Programme (CASP). The CASP information was tabulated and then all studies were compared and contrasted. The key characteristics of each article were entered into Excel, and then analyzed to generate themes. According to the CASP qualitative tool the studies were of reasonable methodological quality, with most studies addressing the majority of questions. Themes that emerged from the article findings were: (1) educators are the instruments of occupation-centered education and (2) learning in context and through doing form distinctive pedagogies. The review provided insights about strategies being used by educators to teach occupation such as teaching it as a concept related to self and as a tool for practice, and the use of active and experiential learning approaches. It was evident that the scholarship for teaching occupation is in its early stages. Further research using diverse methods is needed to support the development of evidence-based guidelines for teaching occupation.
Technology Import and China’s Innovation Capability: Does Institutional Quality Matter?

With the rapid growth of China’s economy, technology import plays a crucial role in enhancing regional innovation capability. Based on inter-provincial panel data from 2007 to 2016, this paper uses three benchmark linear regression models of Ordinary Least Squares (OLS), Difference-Generalized Method of Moments (DIFF-GMM), and System-Generalized Method of Moments (SYS-GMM) to explore the improvement of China’s regional innovation capability by technology import. Then, the regional institutional quality level is measured from the three dimensions of politics, economy, and law, and the two-step difference GMM threshold panel model is used to analyze the effect of technology import on regional innovation capability under different institutional quality conditions. The results show that: (1) In the benchmark linear regression model, technology import has a significant role in promoting regional innovation capability. (2) With the rise of regional corruption, the quality of political institution declines, and the promotion effect of technology import on regional innovation ability is weakened. (3) The improvement of the marketization level and intellectual property protection level strengthen the role of technology introduction in promoting regional innovation capability. On the contrary, in regions with low economic and legal institutional quality, technology import has no significant impact on regional innovation capability.
Cooperation Strategy in the Business Ecosystem and Its Healthiness: Case of Win - Win Growth of Samsung Electronics and Partnering Companies

With increasing adoption of smart products and complexity, companies have shifted their strategies from stand alone and competitive strategies to business ecosystem oriented and cooperative strategies. The win-win growth of business refers to corporate efforts undertaken by companies to pursue the healthiness of business between conglomerates and partnering companies such as suppliers for mutual prosperity and a long-term corporate soundness based on their business ecosystem and cooperative strategies. This study is designed to validate a theoretical proposition that the win-win growth strategy of Samsung Electronics and cooperative efforts among companies can create a healthy business ecosystem, based on results of case studies and surveys. In this study, a level of global market access of small and mid-sized companies is adopted as the key achievement index. The foreign market entry is considered as one of vulnerabilities in the ecosystem of small and mid-sized enterprises (SMEs). For SMEs, the global market access based on the research and development (R&D) has become the critical component in the process of transforming them into global small giants. The results of case studies and surveys are analyzed mainly based on a model of a virtuous cycle of Creativity, Opportunity, Productivity, and Proactivity (the COPP model) that features the characteristics of the healthiness of a business ecosystem. In the COPP model, a virtuous circle of profits made by the first three factors and Proactivity, which is the manifestation of entrepreneurship that proactively invests and reacts to the changing business environment of the future, enhances the healthiness of a given business ecosystem. With the application of the COPP model, this study finds major achievements of the win-win growth of Samsung Electronics as follows. First, Opportunity plays a role as a parameter in the relations of Creativity, Productivity, and creating profits. Namely, as companies export more (with more Opportunity), they are more likely to link their R&D efforts to Productivity and profitability. However, companies that do not export tend to fail to link their R&D investment to profitability.
Perception of Political Leadership in Local Governments in Latvia

Theme of the paper is political leadership in local governments in Latvia. The work uses secondary data analysis and case studies. The aim of the study is to find out what kind of role does the chairperson of the municipality have as a political leader and what kinds of factors are influencing him/her. The results revealed that formally the chairperson of the municipality has no decisive influence on the municipality and that both types of factors (internal and external) interact with each other limiting the political leader’s (chairperson’s of a municipality) freedom of action.

This report describes a submission for IEEE AASP Challenge on Detection and Classiﬁcation of Acoustic Scenes and Events (DCASE) 2020 for Task 1 (Acoustic Scene Classiﬁcation (ASC)), sub-task A (ASC with multiple devices) and sub-task B (low-complexity ASC). The systems exploit time-frequency representation of audio to obtain the scene labels. The system for sub-task A follows a simple pattern classiﬁcation framework employing wavelet transform based mel-scaled features along with support vector machine as classiﬁer. Texture features, namely local binary pattern, extracted from log of mel-band energies is used in a similar classiﬁcation framework for sub-task B. The proposed systems outperform the deep-learning based baseline systems with the development dataset provided for the respective sub-tasks.
Anthropogenic CO2 — Seasonal Fossil Fuel Emissions in CCDAS

A seasonal cycle of fossil fuel CO2 emissions replaces an intra-annually invariant background flux in the global carbon cycle model CCDAS (Carbon Cycle Data Assimilation System). CO2 emissions are divided into five regions. The fossil fuel seasonality function is a basic sinusoidal cycle with terms varying latitudinally and monthly. A tuneable parameter representing the amplitude and phase of the cycle in each region is calibrated through data assimilation of atmospheric CO2 concentrations at 41 observation
OPTIMIZATION OF NANOSTRUCTURED ZnO-PARTICLE FABRICATION ROUTE WITH DIFFERENT ALCOHOLS AND VARYING SODIUM HYDROXIDE CONCENTRATION

Nanostructured zinc oxide particles are fabricated with the sol-gel technique. The influence of the sodium hydroxide concentration, type of alcohol, and temperature are investigated using fractional factorial experimental design. Parameter ranges were zinc acetate concentration from 0.5 M to 1.5 M, sodium hydroxide concentration from 0.8 M to 2.4 M, annealing time from 20 h to 60 h, and oven temperature from 40 °C to 100 °C. A white precipitate is obtained with slowly adding zinc acetate dehydrated onto sodium hydroxide, under agitation. Such precipitate is washed three times in deionized water and ethanol. The resulting particles are characterized by scanning electron microscopy. A highly homogenous production of nanostructured particles is obtained with Zn(CH3COO)2 =0.5 M, NaOH=2.4 M, T=100 °C, t= 20 h.
001-128 Tourism 2016 01EN.indd

Th e conceptual framework of ecostrategies (views and use of landscape) presented here have been used to analyse various cases of nature-based tourism and related activities such as outdoor recreation, outdoor education, nature reserves and conservation. Th e role of the ecostrategies is to illustrate the intersections, confl icts and alliances between diff erent types of nature based tourism and relations to other rural activities. Th e framework consists of four main ecostrategies, which are identifi ed from the tension between "functional specialization"vs. "territorial adaptation" and the tension between the ideals of "utilization" vs. "appreciation". Th e four ecostrategies are the landscape seen as: (i) a museum for external consumption, (ii) a factory for producing activities and products, (iii) a dedicated place to be utilized and (iv) a dedicated place to be contemplated. Th ese ecostrategies are linked to various consequences in terms of democracy, environmental issues, views of nature, local development, planning, pedagogy, identity and confl icts. Th e framework has proved fruitful in discussions about landscape futures, as illustrated by the case studies on nature based tourism, outdoor recreation and nature reserves presented in the article. Some of the framework's shortcomings are here presented, together with suggestions for further development, such as quantitative survey investigations and using a three-dimensional version to illustrate previously hidden tensions.

An evaluation of methods to port legacy code to SGX enclaves

The Intel Security Guard Extensions (SGX) architecture enables the abstraction of enclaved execution, using which an application can protect its code and data from powerful adversaries, including system software that executes with the highest processor privilege. While the Intel SGX architecture exports an ISA with low-level instructions that enable applications to create enclaves, the task of writing applications using this ISA has been left to the software community. We consider the problem of porting legacy applications to SGX enclaves. In the approximately four years to date since the Intel SGX became commercially available, the community has developed three different models to port applications to enclaves---the library OS, the library wrapper, and the instruction wrapper models. In this paper, we conduct an empirical evaluation of the merits and costs of each model. We report on our attempt to port a handful of real-world application benchmarks (including OpenSSL, Memcached, a Web server and a Python interpreter) to SGX enclaves using prototypes that embody each of the above models. Our evaluation focuses on the merits and costs of each of these models from the perspective of the effort required to port code under each of these models, the effort to re-engineer an application to work with enclaves, the security offered by each model, and the runtime performance of the applications under these models.
