Abstract:
Background: The use of plastic shopping bags increases and poses tremendous pressure on the local environment. However, little is known about its utilization among different population categories and their perception of its utilization and willingness to use other sustainable alternatives. This study aimed to assess the community’s perception toward the use of plastic shopping bags and its options in Jimma town, Ethiopia Methods: A community-based descriptive cross-sectional study design was conducted on 351 customers and retailers selected from the town’s main marketing areas. The data was collected using a structured questionnaire in a face-to-face interview and analyzed using SPSS v.21. Results: The results show that all the respondents use plastic shopping bags for different shopping services. The majority (147 (41.9%)) of the respondents said that they use 5 to 10 shopping bags, and 66 (18.8%) use more than 10 shopping bags per week. Participants responded with different reasons for the frequent use of plastic bags for shopping. Accordingly, 116 (33.0%) responded that plastic bags are cheap, 92 (26.2%) use them due to lack of alternatives, and 89 (25.4%) responded that plastic bags are light and convenient to use. However, 326 (93%) of the respondents support efforts to reduce single-use plastic bags, 284 (80.9%) support a ban on single-use plastic bags, and 319 (90%) were willing to pay for alternative shopping bags. Conclusion: Communities are aware of the environmental problems associated with the intensive use of plastic shopping bags, their wastes, and the need for alternative options. However, it will continue to pose significant environmental challenges unless low-cost and environment-friendly alternative options are available.

Abstract:
Abstract The rapid urbanization and economic growth have caused increase of plastic products globally. The least developed countries (LDCs) have been facing severe problems with solid waste due to lack of people’s awareness, lack of skilled manpower to handle waste and necessary equipment to manage in sustainable manner. Nepal, a LDC in South Asia, lacks source segregation leading the maximum plastic items reaching to the landfill site. It is even difficult for the planning authorities to make effective plans for sustainable management of plastic waste due to lack of waste generation data. Nepal has made many rules and directives to ban plastic bags till date but has failed in its implementation. This study is the first of its kind to capture the perception of youths towards single use bags in Nepal. This study was conducted among 569 Nepalese youths of age between 18-40 years. A closed ended self-administered questionnaire was distributed among the respondents and responses were collected for three weeks. The questionnaire was prepared using google form and distributed via Facebook. A snowball method was used where the respondents were asked to share the questionnaire in their network. It was found that majority of Nepalese youths have been practicing the source segregation at their houses. The use of single use plastic is very common in Nepal with an individual using at least 208 plastic bags in a year. The gender and source segregation of waste was statistically significant with p-value of 0.02 (<0.05). The main reason of using plastic bags was its easy availability. There is lack of alterative to the plastic bags in Nepal. However, the youths are ready to support the government plastic ban policy and have asked the alternatives to the plastic bags. The result has shown that the Nepalese people have negative perception towards single use plastics and are in search of alternatives. The government need to implement heavy penalty for producing plastic bags greater than 30 micron and deploy tax with shop keepers and customer if found using it.

Abstract:
Malaysia is one of the worst countries overflowed with tonnes of single-use plastic waste in Asia. Our reliance on these plastics means we are accumulating waste at a staggering rate. The users flavor single-use plastic due to the fact durable, cheap, easy to obtain, and makes packaging convenient. Single-use plastic packaging such as plastic cups and straws, wrapper, plastic cutlery, and plastic bags are used by humans every day. The overuse of single-use plastic harmed the ecosystem, human health, and the image of Malaysia. Therefore, this study aims to create public awareness about the seriousness of single-use plastic waste's effect on their living environment and encourage the audiences to reduce using the these-use plastic product. An in-depth interview has conducted with two environmental-based experts and an environmental organization to understand more information about the single-use plastic issue in Malaysia. A few alternative materials to replace single-use plastic has been introduced: edible cutlery, bio-degradable grocery bags, paper bag, bamboo, and paper straw. Hence, the public must be concerned about single-use plastic issues to reduce the unnecessary usage of plastic, which will increase the burden on the environment. This study will benefit the Government and agencies related to how to solve the single-use plastic issue.

Abstract:
Single-use plastic bags are increasingly becoming unpopular across the globe due to growing concerns over plastic pollution, which is threatening both terrestrial and marine ecosystems. Creating policy interventions to reduce plastic consumption requires objective information about local conditions. This study uses a choice experiment to elicit consumer preference for attributes of shopping bags from a sample of 250 consumers in Cape Town. Following the literature, we estimate the conditional logit model and the mix logit model and perform appropriate tests to establish a model which fits our data. Our results show that consumers in Cape Town prefer small and medium-sized bags relative to the status quo. They also care about durability, reusability, style, and recyclability of shopping bags. The highest willingness to pay is associated with a medium-sized shopping bag (R3.76), followed by a shopping bag that is reusable (R3.35), then a shopping bag that is styled (R2.16), then a small-sized shopping bag (R1.74), then a durable shopping bag (R1.50) and finally a recyclable shopping bag (R1.25). By aggregation, the willingness to pay of a small-sized shopping bag that is recyclable is R2.99 which is equivalent to the maximum price that the respondent is offering for a single-use plastic bag (R2.92). The willingness to pay of a medium-sized and reusable shopping bag is R7.11 per unit which is at least as high as the minimum price that respondents would consider for alternative packaging (R7.37). Finally, taking into consideration all the important attributes, we arrive at a willingness to pay ranging from R9.99 to R12.01 per bag for a small and medium shopping bag, respectively. Our results call for a combination of policy instruments such as a subsidy on expensive durable and reusable shopping bags to increase demand while at the same time increasing the levy on single-use plastic bags to reduce demand. More effort is needed to increase appreciation and perception of recyclable products.

Abstract:
From an environmental point of view, the improvement on bio-based technologies to produce “Green-plastics” could contribute to improve the sustainability of single-use items. In this frame, the present work investigates raw materials for producing single-use plastic shoppers so that they might increase their sustainability. Two approaches have been addressed: first the reuse of regenerated materials recovered from internal wastes from traditional oil-based polymers, and, as an alternative, the use (and possibility of reuse) of biodegradable bio-based plastics. Hence different raw materials were analysed and their properties discussed.

Abstract:
This chapter explores the principles of a low-tech approach that are developed and rooted in the search for simplicity and conviviality, localization, design, and manufacture for true sustainability. It describes paths to be taken and general principles on low-tech based on the conscious rejection of the hope of a successful outcome based on technological breakthroughs still to come. It also elaborates the principle of simplicity as the immense advantage of the pure and simple suppression of need that aims to effectively reduce the rate of consumption of resources. The chapter mentions examples of ways to reduce the non-negotiable standard of living, such as a ban on advertising materials, trainers that flash when walking, or single-use plastic bags. It analyses the main problem of the high-tech world under the pretext of seeking greater effectiveness and technical efficiency.

Abstract:
Joseph Späh had to feed his dog; nothing strange about that. The problem was that Ulla, an Alsatian, was mostly confined to the freight room—off limits to passengers. Had everything gone according to schedule, this would not have been an issue either, except for gruff remarks from crewmen not appreciating the needs of this canine friend and co-worker in Späh’s stage act. But this flight did not go according to plan, and Späh’s frequent visits to the rear of the Hindenburg would give him problems in the years to come. The US Department of Energy, and its counterparts in Europe and Japan, are currently spending billions on developing the use of hydrogen for future energy applications—for example, as a fuel for cars and buses. The main advantage is the clean combustion of this fuel: two molecules of hydrogen gas will combine with one molecule of oxygen and give two molecules of water. The future belongs, perhaps, to the ‘hydrogen economy’, but unfortunately for its proponents, the popular history of hydrogen as a fuel is bound up with the tragedy of the Hindenburg. We will get back to Joseph Späh’s poor dog in a while, but for now ponder the fact that over the dog, and above everyone else aboard the comfortable and luxurious Hindenburg , there were huge ‘bags’ filled with hydrogen—the lightest of all the elements, with only one proton and one electron. It has the lowest density of any gas, and is formed by two hydrogen atoms combined together via a single chemical bond, made by sharing the two negatively charged electrons between the two positively charged nuclei. This H2 gas had carried the world’s largest airship from Frankfurt to Lakehurst outside New York, and before that on successful tours all over the globe during the preceding year. These days, we tend to wonder how people could even contemplate the idea of travelling around in what can be described as a flying bomb.

<em>Abstract</em>.—In Lake Martin (16,000 ha), Alabama, black bass <em>Micropterus </em>spp. tournaments occur nearly every weekend at a single site (Wind Creek State Park [WCSP]), which could cause fish to accumulate at this release site and potentially cause negative impacts to the population. Over a 7-month period, nearly 6,600 tour-nament-caught largemouth bass <em>M. salmoides </em>and spotted bass <em>M. punctulatus </em>were injected with a coded wire tag at different body locations before release at WCSP. After release, black bass were collected with electrofishing up to 1.5 years following release at 0–10 km from the release site and scanned for a tag. Although variable, a substantial proportion (10–70%) of tournament-caught black bass comprised the black bass population within 3 km of WCSP up to 3 months after release. After 3 months, proportions of tagged black bass within 10 km of WCSP decreased dramatically and by an order of magnitude after 1 year, which strongly suggested that these fish dispersed from WCSP. Over a 2- to 70-d period after release from a tournament, relative weights of tournament-released black bass were typically less than fish not released in tournaments. In addition, we collected and aged black bass throughout Lake Martin; relative weights of both black bass species were less and spotted bass growth was lower within 10 km of WCSP compared to other regions of Lake Martin. Even though black bass dispersed from the WCSP release site, these negative population effects were attributed to the constant translocation and accumulation of tournament-caught fish in this region of Lake Martin. In water bodies such as Lake Martin where mass translocation of black bass occurs annually at a single site, the use of live-release boats to transport tournament-caught black bass and the promotion and use of alternative release sites should be encouraged to reduce possible localized negative population effects.

Abstract:
Fertilizers for soil on which plants grow come in a variety of forms, such as organic, inorganic, single nutrient, double nutrient, complete fertilizer (contains N, P, and K in that order), speciality fertilizers, composts, and manures. Information about each of these forms follows. Most of the N used in fertilizers is derived from a synthetic process developed by Europeans called the “Claude-Haber process.” This process uses nitrogen gas (N2) from the atmosphere along with hydrogen gas (H2) from natural gas in a device where pressure can be increased and temperature can be raised. The reaction is accelerated using an iron catalyst and removing the product (NH3) as it is formed. The Fe catalyst is subject to poisoning from impurities, such as As, Co, P, or S. Anhydrous ammonia has the highest percentage of N and the cheapest per unit of N since no processing is involved. Anhydrous (without water) ammonia is a gas but when compressed changes to a liquid. For application to soils a pressurized tank is required with a device to inject the liquid ammonia into the soil. Upon release of pressure, the liquid changes back to a gas; however, the ammonia gas reacts with the moisture in the soil to form NH4+ that is available for plants. One problem with ammonia is that NH3 gas is toxic to seedlings and growing plants, so must be applied prior to planting. This limits its use for landscape projects. Salt solutions of aqua ammonia are obtained by dissolving ammonia gas, ammonium nitrate, or urea in water. The amount dissolved will vary the concentration of N in the final product. This can be used in landscape projects, but care must be used as this material can salt out and plug up orifices when sprayed onto a soil. There is no real difference between liquid or solid fertilizers, provided the percentage of N is the same. Ammonia Nitrate [NH4NO3] (33.5% N) Ammonium nitrate is formed by ammonia gas reacting with nitric acid: . . . NH3 + HNO3 → NH4NO3 . . . This material is hygroscopic (absorbs water from the air) and requires moisture-proof bags for storage.

Abstract:
The object of research is a cheap, easy-to-build basic module and multi-platform sets, obtained by combining basic modules with dimensions corresponding to typical railway containers: 10' (with a length of up to 3m), 20' (length of up to 6m), 30' (length of up to 9m). Such structures can be used to support the intermodal rail-road transport of wooden and metal logs. Such a structure with various longitudinal dimensions ensures high mobility resulting from the modular structure and the possibility of selecting transport configurations as well as the use of various forms of loading / unloading, including: typical crane operations, the use of forklifts or hook winches. The use of a platform-container will eliminate the need to repeat the operation of individual loading or unloading of each unit of the transported load (e.g. a single block of wood, a bundle of bars, as a metal log, a single pipe, etc.) during each reloading operation (from the place of logging, production, storage, etc.). A single basic module of the platform has the dimensions of a 10' railway container.

Abstract:
Objectives. To evaluate the association of cannabis use, genes of the endocannabinoid system and their interaction on clinical symptoms and cognitive performance in patients with a first-episode of pyschosis. Background. The role of both cannabis use and individual genetic background has been shown in the risk for psychosis. However, the influence of cannabis and variability at endocannabinoid genes on the psychosis outcome still remains inconclusive. Materials and Methods. The sample comprised 43 Caucasian individuals with a first-episode of psychosis (mean age(sd)=25.80(6.39) years, 76.7% males, 51.2% cannabis users).There were no differences in age and sex between cannabis users and non-users. Genetic variability was assessed by genotyping one Single Nucleotide Polymorphism (SNP) in each gene (CNR1-rs1049353 and CNR2-rs2501431). Clinical (PANSS, GAF) and neuropsychological (WAIS, WMS, BADS) scales were administered. Results and conclusions. Genotypic frequencies did not differ between cannabis users and non-users. Cannabis use was associated with better manipulative abilities (IQ-M-WAIS, p=0.029) and better executive function (BADS, p=0.036). CNR1-T allele carriers presented higher disorganized and negative syndrome scores (p=0.001 and p=0.044, respectively). The interaction models evidenced a combined effect of CNR1 and cannabis use on the negative syndrome-PANSS (p=0.037). These results suggest the role of cannabis use and genetic background on cognitive and psychopathological outcomes in first-episode psychosis. However, evidence is still scant, and further investigation in larger samples is needed.

Abstract:
This paper presents an approach that uses topic models based on LDA to represent documents in text categorization problems. The document representation is achieved through the cosine similarity between document embeddings and embeddings of topic words, creating a Bag-of-Topics (BoT) variant. The performance of this approach is compared against those of two other representations: BoW (Bag-of-Words) and Topic Model, both based on standard tf-idf. Also, to reveal the effect of the classifier, we compared the performance of the nonlinear classifier SVM against that of the linear classifier Naive Bayes, taken as baseline. To evaluate the approach we use two bases, one multi-label (RCV-1) and another single-label (20 Newsgroup). The model presents significant results with low dimensionality when compared to the state of the art.

Abstract:
Abstract Through asset lifecycle, data is collected for a variety of purposes across multiple disciplines, and exists in various formats and repositories. Decommissioning projects utilize and repurpose a multitude of these datasets; from use in analysis and planning, to facilitating systematic environmental assessments, and meaningful discussion with stakeholders. The key challenge is how do we consolidate historical data, incorporate new data, and make it evergreen to support planning and informed decision making; and how do we coordinate large volumes of previously disparate data in a meaningful way for all users with a simple access model? A team of geographic information system (GIS) practitioners and subject matter contacts in technical and health, safety and environment (HSE) disciplines was convened to collect, sort, and compile known historical offshore data, including, but not limited to; pipeline and structural inspections and environmental studies, all captured via Remote Operated Vehicle (ROV), Side Scan Sonar (SSS), and sampling programs. Data was reformatted to standardize headers and attributes allowing for merging of existing like-data and to support new data integration. To this end, we also worked collaboratively with vendors to optimize data collection and improve alignment with our internal data structures. The Esri GIS technology was utilized for data integration, specifically the web and mobile environments. Through these environments, non-GIS users could easily access data and focused applications, supporting ease of data visualization and allowing for a single view of data spanning decades and covering multiple themes. This enabled an enhanced understanding of the offshore environment, allowing us to identify gaps and focus areas for future data capture, helping to facilitate cross-discipline discussions, and identification of operational synergies; improving access, efficiency, and reducing decommissioning costs. Data integration resulting from this initiative and delivery through a spatially aware GIS environment is providing unprecedented access to a vast scope of cross-disciplinary data previously not possible with more traditional engineering methods and data formats. Data accessibility aids communication, and when combined with early engagement across multi-disciplinary teams, the path to decision making is reduced, synergies gained, and costs are reduced through improved efficiency and optimization.

Abstract:
The engineering structures composed from the rods (frames, trusses, etc.) are widely used in the various industrial applications. There are many publications presenting a theoretical modeling of the rod-based structural systems especially for the designs constructed from the thin-walled components. Usually, the single bar element of such system is taken as the basis for the general model development. The growth of the use of fast computer techniques has resulted in the extensive development of numerical methods where the main role belongs to the finite-element analysis. This paper presents a new approach to the numerical simulation and dynamic analysis of the rod systems based on the use of graphs in the numerical solutions for this class of problems. The main idea is that the solution of the global 3D problem for the whole system can be split into the number of simple one-dimensional problems for the individual elements (bars). Then, at each step of the numerical integration, these one-dimensional problems are linked with the common solution procedure for the original system using additional systems of equations written for the nodes (bar joints). In this way, the global coupling for all the original problem variables is guaranteed. Implementation of this method is illustrated in this paper for the flat two dimensional rod systems and incorporates finite-difference methods. The rod systems under consideration could be composed from an arbitrary number of the rectilinear bars/rods with different geometrical and physical characteristics. Also, the random topology of the bar joints and reactions in the system nodes can be realized. The advantage of the proposed approach is that not only dynamical behavior of the whole system, but also the transition nonstationary processes in the system components could be simulated for various combinations of the load applied and boundary conditions imposed.
