ANÁLISE DO DESCARTE DE RESÍDUOS SÓLIDOS COM TINTAS EM UMA EMPRESA ESPECIALIZADA EM EMBALAGENS DE PAPELÃO ONDULADO: ESTUDO DE CASO

The present work aims to analyze the treatment procedures of waste ink used in the stamping of packaging made from corrugated cardboard and to measure the relevance of the reuse of treated effluents to rationalize water in the production process. This is a cross-sectional case study, whose objective was to narrow the knowledge about specific treatment of the nature of effluents, which allowed to explain this phenomenon with scientific basis. Control of the reuse water pH is extremely important in the strategy of sending it to the sewage system and extreme changes have implications for the quality of water intended for human consumption. It was verified that the pH range obtained from the company's reuse water collection resided at 7.8 on the measurement day, presenting a satisfactory condition. The use of aluminum sulfate as a coagulant enables efficiency in turbidity removal and pH control. It is concluded that environmental gains are obtained both in reducing water abstraction and reducing pollutant emissions to the environment, preserving this natural resource in quantity and quality.
The Issue of Endogeneity and Possible Solutions in Panel Data Analysis in The Hospitality Literature

This study discusses endogeneity and causality issues in analyzing panel data and presents possible suggestions to alleviate them. Establishing causality is of paramount interest for researchers, yet the hospitality literature has tended to employ econometric techniques that rely heavily on modeling assumptions for endogeneity problems. Accordingly, this article provides practical guidance for hospitality researchers in addressing endogeneity issues when analyzing panel data. Specifically, this article (a) discusses endogeneity issues in the use of panel data, (b) suggests possible remedies to mitigate endogeneity problems, (c) reviews how the existing hospitality literature has previously dealt with such problems, and (d) suggests how hospitality researchers can effectively address endogeneity issues with reference to an example of difference-in-differences methods using restaurant panel data.
Detecting Covert Members of Terrorist Networks

Terrorism threatens both international peace and security and is a national concern. It is believed that terrorist organizations rely heavily on a few key leaders and that destroying such an organization’s leadership is essential to reducing its influence. Martonosi et al. (2011) argues that increasing the amount of communication through a key leader increases the likelihood of detection. If we model a covert organization as a social network where edges represent communication between members, we want to determine the subset of members to remove that maximizes the amount of communication through the key leader. A mixed-integer linear program representing this problem is presented as well as a decomposition for this optimization problem. As these approaches prove impractical for larger graphs, often running out of memory, the last section focuses on structural characteristics of vertices and subsets that increase communication. Future work should develop these structural properties as well as heuristics for solving this problem.
Charge‐Separation Dynamics in Inorganic–Organic Ternary Blends for Efficient Infrared Photodiodes

Knowledge about the working mechanism of the PbS:P3HT:PCBM [P3HT=poly(3‐hexylthiophene), PCBM=[6,6]‐phenyl‐C61 ‐butyric acid methyl ester] hybrid blend used for efficient near‐infrared photodiodes is obtained from time‐resolved photoluminescence (PL) studies. To understand the role of each component in the heterojunction, the PL dynamics of the ternary (PbS:P3HT:PCBM) blend and the binary (PbS:P3HT, PbS:PCBM and P3HT:PCBM) blends are compared with the PL of the pristine PbS nanocrystals (NCs) and P3HT. In the ternary blend the efficiency of the charge transfer is significantly enhanced compared to the one of PbS:P3HT and PbS:PCBM blends, indicating that both hole and electron transfer from excited NCs to the polymer and fullerene occur. The hole transfer towards the P3HT determines the equilibration of their population in the NCs after the electron transfer towards PCBM, allowing their re‐excitation and new charge transfer process.
Selective Androgen Receptor Modulators(SARMs): A Mini-Review

Selective Androgen Receptor Modulators (SARMs) were discovered in the late 1990â€™s.They may have an application in treatments of various diseases, including muscle wasting, cancer cachexia, breast cancer, osteoporosis, andropause and sarcopenia. In this minireview the development, pharmacodynamics, and the phase 1 and 2 trial results of the SARMs are discussed with a special emphasis on the illicit use of the SARMs.
North-South Environmental Debate: Strategic Price Distortions And Capital Flows

En nuestro modelo, los gobiernos del norte tienen un incentivo para establecer regulaciones ambientales debiles, con el fin de aumentar su productividad y el precio de sus capitales de exportacion. Nosotros investigamos el efecto de esta distorsion sobre los incentivos para la proteccion del medio ambiente en el Sur. Bajo ciertas condiciones, el Sur responde con una disminucion en la proteccion del medio ambiente. Por lo tanto, las distorsiones estrategicas de precios conducen a un ambiente globalmente mas sucio.
1 1 Accessibility and Distance in Graphs

We explore ways of introducing Euclidean distances associated with street systems represented by axial lines into the two connectivity graphs based on points (or street junctions), and on lines (or streets), the so-called dual and primal representations of the space syntax problem. As the axial line is embedded in the connectivity graph between the points, for the dual problem the specification of Euclidean distance between points is relatively trivial but for the original syntax problem, this is problematic in that it requires us to find a unique point representation for each line. The key is to find the centroids of the lines (of sight or unobstructed movement) between the points on each axial line, and then to use these to form a weighted centroid of centroids. The distances between axial lines which form paths through the connectivity graph between streets, are then computed using these centroids as starting points for each line and routing distance through the street junctions. There are many issues involving interpretation of these measures. It might be thought that the longer an axial line, the more important it is. But by giving an axial line distance, this suggests that this is a deterrence to interaction, as in spatial interaction theory, with longer axial lines being individually less important, notwithstanding the probability that they are better connected within the overall street system. Clearly in many finer-scale morphologies, this assumption might not be tenable but the measures developed here can be easily adapted to various circumstances. What this focus on distance enables us to do is to treat a ‘mixed syntax’ problem where we are able to embed truly planar graphs into the axial map. This extends the technique to deal with systems not only comprising streets down which we can see, but also fixed rail lines, subway systems, footpaths and so on which currently are hard to handle in the traditional theory. We illustrate the extended theory for a pure syntax problem, the French village of Gassin, and a mixed syntax problem based on the grid of streets and underground railways in central Melbourne. In conclusion, we introduce the notion that proximity or adjacency at different orders might form more appropriate measures of syntax distance, the proximity of nodes to nodes and lines to lines in the dual and the primal being illustrated for both Gassin and central Melbourne.
Are You a Robot? Revitalizing Online Learning and Discussion Boards for Today’s Modern Learner

Abstract Engagement and motivation of online students have been explored by many online instructors and researchers. This article presents the rationale that online engagement is best achieved when both students and instructors are actively motivated by course learning and objectives. Modern learners enjoy interactive and practical exercises to demonstrate their knowledge in addition to student-instructor contact. Instructors can bring their best to the class when they use creative and innovative teaching strategies that foster student learning and its application. Tips to enhance student and instructor engagement in online courses, particularly through online discussion boards, are explored which can help to positively impact the online class experience.
Low-Complexity Multi-User Parameterized Beamforming in Massive MIMO Systems

In this paper, we design a complexity-reduced transmission scheme in massive antenna environments. To reduce the implementation complexity for the generation of beam weight, we design a multi-user parameterized beamforming (MUPB) scheme that can control the beam direction using a single parameter with combined use of maximum ratio transmission and partial zero-forcing scheme that partially nulls out interference. We design the MUPB to maximize the signal-to-leakage plus noise ratio (SLNR). To further reduce the implementation complexity, we optimize the MUPB based on approximated SLNR instead of accurate SLNR. Finally, the performance of the proposed MUPB is verified by computer simulation.
Valuing Multidimensional Environmental Changes with Contingent Ranking

Assessment of multidimensional environmental change requires specialized valuation methods, of which contingent ranking is one candidate. Luce’s Choice Axiom permits an easy linkage between ranking and choice through the Cascading Choice Theorem which states that a ranking of alternatives is equivalent to a sequential choice process. The Reversibility Paradox shows this to be an untenable assumption. In light of this is the contingent ranking method modified to an experimental procedure which explicitly elicits an incomplete ranking of the alternatives through a sequential choice process. The theoretical and statistical properties of such a valuation method are discussed.
Psychological Wellbeing and Healthy Aging: Focus on Telomeres

Stress and depression are known to modulate the aging process, and might also affect telomere biology. In fact, exposure to some biochemical pathways involved in stress-related depression may contribute to an ‘‘accelerated aging” phenotype, as well as the incidence of age-related diseases, including metabolic disorders and dementia. Basic studies support the notion that the telomere and telomerase system plays a pivotal role in the aging process and disease promotion. Interestingly, short and dysfunctional telomeres are associated with reduced lifespan, as shown in animal models. In this context, telomeres are very sensitive to stress, mindset, and lifestyle, and their rescue may be sufficient to restore cell and organism viability. This mini-review discusses conceptual models of healthy and active aging and their relationship with telomere biology and mental health.
Participatory Design and Participative Practices in Small Companies

Small companies are mISSing from the literature of Participatory Design. Yet participative practices are important in the design of any job. This paper considers the relations between the work practices and technology needs of small companies, and the discourses of Participatory Design. Because small companies use off-theshelf technology, these relations are shaped by the geographic and cultural separation between the situation of use and the situation of design. User participation focuses on shopping decisions, and the fitting of purchased technology to the local work situation. While many aspects of job design can be extremely flexible within small companies, participation in the design of computer systems is bounded by the available products, and the options for continuing design-in-use that are embedded within them.
Improved dynamic response strategy with dual phase‐shift control for dual‐active‐bridge DC–DC converter

In this study, an improved dynamic response strategy with dual phase-shift (IDR-DPS) for dual-active-bridge (DAB) DC–DC converter is proposed to improve system performance and eliminate DC bias caused by power mutation. Firstly, a unique combination of independent variables about inner and outer phase shift duty ratios is calculated at a given reference power through combining the minimum current stress calculation method with DPS control, which makes DAB run efficiently. On this basis, a DC bias elimination method is proposed to eliminate DC bias current in half a switching period through modifying inner duty ratios during transient process and drive DAB to reach new steady state quickly. Finally, a DAB topology platform is built to perform experiments of proposed IDR-DPS strategy and traditional direct control, the effectiveness of the proposed strategy is verified by comparative experiments.
Pokémon GO! GO! GO! The impact of Pokémon GO on physical activity and related health outcomes.

© mHealth. All rights reserved. mHealth 2020 | http://dx.doi. org/10.21037/mhealth-20-121 Many previous studies have established that a sedentary lifestyle is associated with the risks of disease incidence as well as mortality (1-3). In fact, the World Health Organization (WHO) considered physical inactivity as a leading factor for global mortality (4). In 2013, the WHO proposed the Global Action Plan [2013–2020], aiming to prevent and control noncommunicable diseases; one of the targets is to reduce 10% of relative prevalence of insufficient physical activity by 2025 (5). This is in consideration of the threat from physical inactivity as well as a high prevalence of physical inactivity and sedentary behaviors (6,7), but also in addition to strong evidence suggesting that the risks of incidence (8) and mortality (9,10) can be reduced by decreasing sedentary time especially when physical activity is improved. For physical inactivity, useful and sustainable interventions, especially ones that are scalable and applicable to a wide range of audiences, are rare. Recent study has indicated that using digital devices with exercise-related games may increase physical activity (11). As one of the most popular mobile games of all time (12), Pokémon GO maintained an estimated 147 million monthly active users as of May 2018 (13), achieved more than a billion downloads by early 2019 (14), and brought in $1.4 billion of revenue in 2019, which ranked sixth among free-to-play games (15). Through catching Pokémon, this locat ion-based augmented reality (AR) mobile game encourages players to “explore real locations and search far and wide” (16). Because of this feature, as well as its wide popularity around the world, whether the game can improve physical activity is of great interest in society. Accordingly, some related studies have been subsequently conducted and published since the game’s release. A recent systematic review and meta-analysis has summarized the results from 16 observational studies and one pre-post study (17). In this review study, the time interval for publication search is from July 2016 to October 2018, involving eight databases. Through comparing Pokémon GO players vs. non-players, and prevs. post-play time points, the authors concluded that playing Pokémon GO was associated with decreasing sedentary behaviors, as well as increasing walking duration, walking distance and number of steps per day. Some newly published studies after October 2018 also provide evidence of improving physical activity by Pokémon GO (18,19), except one study found that greenway Pokémon GO players may have more stopping and slower pace of walking compared to greenway non-Pokémon GO players (20).

Effect of a natural phenolic compound, thymol on alcoholic fermentation

In fermentation with herbs as the base medium, it was observed that certain phytoconstituents affect the pace of fermentation. Trachyspermum ammi is a common ingredient in many herbal based fermentation products especially in Ayurvedic system of medicine. Thymol constitutes 40-50% of the volatile oil in this herb. Thymol is known to be nihibitory lactic acid fermentation. Evaluation of the effect of Thymol in alcoholic fermentation was undertaken Varying concentrations of Thymol 0.3, 0.1 and 0.05% were added to the sugar medium and kept for fermentation. The result of the study showed a complete inhibition of alcoholic fermentation conducted by yeast and Woodfordia fruticosa flowers at Thymol concentrations of 0.3 and 0.1% but a retarded pace was observed in case of lower concentration (0.05%).
- Interner Bericht A univariate method for plane elastic curves

The problem to interpolate Hermite-type data (i.e. two points with attached tangent vectors) with elastic curves of prescribed tension is known to have multiple solutions. A method is presented that finds all solutions of length not exceeding one period of its curvature function. The algorithm is based on algebraic relations between discrete curvature information which allow to transform the problem into a univariate one. The method operates with curves that by construction partially interpolat~ the given data. Hereby the objective function of the problem is drastically simplified. A bound on the maximum curvature value is established that provides an interval containing all solutions.
Self-report measures as complementary exams in the diagnosis of insomnia

[This paper has no abstract. First 111 words are shown] Chronic insomnia disorder (CID) is a highly prevalent sleep disorder and a public health problem (Riemann et al., 2017). It is well recognized as a subjective disorder. Subjective because the diagnosis is fundamentally based on the self-report/complaints of the patients and in the clinical assessment of the sleep expert through a systematic clinical interview – which is the standard method (gold standard) for establishing a diagnosis of CID (Marques et al., 2018). On the contrary, the diagnosis of other sleep disorders demands the so-called objective measures such as polysomnography (PSG) (Riemann et al., 2017). We cannot forget that being CID a subjective disorder, it is important to be exhaustive in clinical assessment.
Spatiotemporal patterns of seed dispersal in a wind-dispersed Mediterranean tree (Acer opalus subsp. granatense): implications for regeneration

Seed dispersal can severely limit the quantity of plant recruits and their spatial distribution. However, our understanding of the role of dispersal in regeneration dynamics is limited by the lack of knowledge of seed deposition patterns in space and time. In this paper, we analyse the spatiotemporal variability of seed dispersal patterns in the Mediterranean maple, Acer opalus subsp. granatense, by monitoring seed rain along two years at a broad spatial scale (2 mountain ranges, 2 populations per range, 4 microhabitats per population). We quantified seed limitation and its components (source and dispersal limitation), and explored dispersal limitation in space by analysing dispersal distances, seed aggregation, and microhabitat seed distribution. Acer opalus subsp. granatense was strongly seed-limited throughout the gradients explored, being always dispersal limitation much higher than source limitation. The distribution of seeds with distance from adult individuals was leptokurtic and right-skewed in all populations, being both kurtosis and skewness higher the year of the highest seed production. Dispersal distances were shorter than expected by random in the four populations, which suggests distance-limited dispersal. Dispersal patterns were highly aggregated and showed a preferential direction around adults. At the microhabitat scale, most seeds accumulated under adult maples. However, there were no more seeds under trees and shrubs other than maple than in open interspaces, implying that established vegetation does not disrupt patterns of seed deposition by physically trapping seeds. When compared with patterns of seedling establishment, limited dispersal ability and inter-annual spatial concordance in seed rain patterns suggest that several potentially safe sites for recruitment have a very low probability of receiving seeds in most maple populations. These findings are especially relevant for rare species such as Acer opalus subsp. granatense, and illustrate how dispersal studies are not only crucial for our understanding of plant population dynamics but also to provide conservation directions.
The Characteristics of Consumer Att itudes in the Food Market in Hungary

The objective of our research was to examine the health status and health behaviour of the Hungarian population in relation of food consumption by identifying relationships between the underlying factors. In our research we used the objective factors from secondary data concerning nutritional status and body image as a framework for the interpretation of the examined relationship of eating attitudes and body attitudes. We chose survey as our test method, it was carried out on a national representative sample of 1000 people. After the examination of the factor structure of the two attitude measuring questionnaire, five consumer groups have been identified by the cluster analysis. The five clusters are: Uncontrolled Impulse Eaters, Dissatisfied Tense, Uninterested, Overweight Impulse Eaters and Conscious Consumers. This segmentation based on eating attitudes and body attitudes could serve as a guidance for health marketing experts and the manufacturers of health protective food to determine and address their target group.
The Trackless Tram: Is It the Transit and City Shaping Catalyst We Have Been Waiting for?

Recent innovations in transport technology are now providing mobility that is cheaper, autonomous, electric, and with improved ride quality. While much of the world’s attention has been on how this can be applied to cars, there have been rapid adoption of these and other technologies in High Speed Rail and Metro Rail systems that run between and across cities. This paper shows how such innovations have now been applied to create the next generation of urban transit system called a Trackless Tram. Trackless Trams are effectively the same as traditional light rail except they run on rubber tyres avoiding disruption from construction for Light Rail, but they retain the electric propulsion (with batteries) and have high ride quality due to rail-type bogies, stabilization technologies and precision tracking from the autonomous optical guidance systems—with infrastructure costs reduced to as low as one tenth of a Light Rail system. As with Light Rail, a Trackless Tram System provides a rapid transit option that can harness the fixed route assurance necessary to unlock new land value appreciation that can be leveraged to contribute to construction and running costs whilst creating urban regeneration. The paper considers the niche for Trackless Trams in cities along with its potential for city shaping through the creation of urban re-development along corridors. The paper suggests that the adoption of Trackless Tram Systems is likely to grow rapidly as a genuine alternative to car and bus systems, supplementing and extending the niche occupied by Light Rail Transit (LRT). This appears to be feasible in any medium-sized or larger city, especially in emerging and developing economies, and case studies are outlined for Perth and Thimpu to illustrate its potential.
