Marine Waste

Marine waste management is crucial for Istanbul because of the significant location for intercontinental transition, international trade, tourism, industry and shipping. This study is the first one realised in Turkey for the detailed characterisation of marine waste. The amount and characteristics of solid wastes originating from beaches, coastlines, sea surface cleaning processes and ships (both cargo and cruise ships) were determined. It was observed that marine wastes includes a significant amount of recyclable materials. Although, it was ascertained that the amount and composition of waste differs according to the collecting sources, the majority of wastes are composed of different types of plastics. The average calorific value of marine waste was determined as 2500 kcal kg-1, which is higher than that of mixed municipal solid waste. There is a lack of studies on the pathways of disposal alternatives of marine waste after collection. As landfilling is the common pathway for disposal after collecting, it is clear that recycle/reuse and energy recovery options are possible for marine waste.

Among the solid wastes produced by textile industry, there is a significant amount of wastes with energetic value and which are usually sent to controlled landfills, without any recovery. This traditional route corresponds to high economical and environmental costs, since wastes can be used as a source of energy and/or materials. With the recycling route strongly restricted due to the presence of mixtures of different types of polymeric compounds, some of them not biodegradable, the study of the feasibility of energy recovery from such wastes is of upmost importance and the aim of the present work. Most of the wastes are valuable resources that can be used as raw materials or as an energy source to produce heat or electricity. In this work the potentiality of energy recovery from solid wastes of some of the Vale do Ave textile units was investigated. For that purpose, wastes have been characterized for their weight loss at 105°C, calorific value and ashes content (after burning out at 850°C). The chemical composition of the ashes was determined by X-Ray fluorescence spectrometry. DSC-TGA tests were performed in two different atmospheres, air and argon, in order to evaluate the thermal behavior of the studied wastes. The characterized wastes showed calorific values not negligible, varying from 3500 to10400 kcal/kg (at dry base), similar to the results obtained by others authors and comparable to solid materials which are traditionally considered as fuels (sugar cane, lignite, etc). A weight loss at (105°C) lower than 6.5% and a maximum ashes content of 15% was achieved. However, some ashes present high contents of heavy metals, which can drives to environmental concerns. By the analysis of the thermal profiles it was found that wastes decomposition takes place at low temperatures (< 600°C) resulting in a small amount of the final solid fraction. Concerning the obtained results, the solid wastes collected from different textile units show high potential for energy recovery.

The combustion characteristics of blends of lignite with various organic waste materials are evaluated in this study in order to assess their potential for energy recovery. Different types of municipal solid waste (i. e. paper, plastic, textile, organic), as well as sewage sludge and agri-residues (sunflower shells) samples were collected from the Western Macedonia region, northern Greece. Mixtures of each one of them with lignite in different proportions (30-50-70 wt.%) were prepared. Proximate analysis, calorific value determination, and thermogravimetry (TGA/ DTG) were performed. Thermal parameters such as ignition temperature, total weight loss, maximum rate of weight loss, peak and burnout temperatures and burnout time were determined from the TG/DTG profiles of the raw materials and their blends. The combined utilization of proximate analysis, calorific value determination and TG/DTG method proved to be an effective method for a preliminary assessment of the energetic potential of raw solid waste ?combustible? materials and their blends with lignite. The analytical results revealed that most of the blends are promising for energy recovery. Regarding the raw wastes, sunflower shells were the most reactive. A non-synergistic effect was found for the blends. Organic and sewage sludge blends revealed the lowest combustibility, which is attributed to the high content of inorganic matter and the heterogeneity of these two types of wastes.

IntroductionInvolving patients and the public in the health technology assessment (HTA) has always been fundamental to NICE. To ensure the appropriate method of patient involvement remains relevant to the evolving types of HTA, NICE uses varying methods of involvement. These methods have been reviewed to ensure they remain current and relevant for HTA now and beyond 2020, and also to give guidance on the approaches that should form a standard baseline and those that could be optional.MethodsWe identified and mapped the different methods of patient involvement used at NICE across five types of HTAs: diagnostics; medical technologies; medicines; ultra-orphan conditions; and surgical procedures. We looked at the varying methods of early engagement identifying similarities and differences, and considered the benefits and challenges of each.ResultsThe different methods of patient and public involvement include: lay members (generalist and topic expert) involved in decision making, individual patient input (written and oral), and patient group (organisation) input (written). The types of involvement fell into the following categories: written group submissions, written individual statements, surveys of individuals, pre-meeting events/workshops, oral testimonies at committees, and written consultation responses. The common methods across all HTA types were generalist lay members and consultations.ConclusionsThis review highlighted the varying methods of involvement at NICE and highlighted additional methods that could be standardised across the different types of HTAs as a baseline. These included patient organisation submissions and a method for additionally including individual patients in each type of HTA. We identified that where patient involvement started early and continued at each stage of the process including a pre-meeting event, it was particularly helpful to the stakeholders’ ability to contribute.

Natural resource managers need up-to-date information about how people interact with public lands and the meanings these places hold for use in planning and decision-making. This case study explains the use of public participatory Geographic Information System (GIS) to generate and analyze spatial patterns of the uses and values people hold for the Browns Canyon National Monument in Colorado. Participants drew on maps and answered questions at both live community meetings and online sessions to develop a series of maps showing detailed responses to different types of resource uses and landscape values. Results can be disaggregated by interaction types, different meaningful values, respondent characteristics, seasonality, or frequency of visit. The study was a test for the Bureau of Land Management and US Forest Service, who jointly manage the monument as they prepare their land management plan. If the information generated is as helpful throughout the entire planning process as initial responses seem, this protocol could become a component of the Bureau’s planning tool kit.

Abstract Schottky diodes are semiconductor switching devices with low forward voltage drops and very fast switching speeds. This paper provides an overview of the common failure modes in Schottky diodes and corresponding failure mechanisms associated with each failure mode. Results of material level evaluation on diodes and packages as well as manufacturing and assembly processes are analyzed to identify a set of possible failure sites with associated failure modes, mechanisms, and causes. A case study is then presented to illustrate the application of a systematic FMMEA methodology to the analysis of a specific failure in a Schottky diode package.

Tourism is an important component of the Indonesian economy as well as a significant source of the country’s foreign exchange revenues. According to the Center of Data and Information - Ministry of Culture and Tourism, the growth of foreign visitor arrivals to Indonesia has increased rapidly by 9.61 percent since 2010 to the present. One of the most potential tourism destinations is Komodo Island located in East Nusa Tenggara. With the island’s unique qualities, which include the habitat of the Komodo dragons and beautiful and exotic marine life, it is likely to be one of the promising tourism destinations in Indonesia and in the world. In 1986, the island has been declared as a World Heritage Site by UNESCO. The Ministry of Culture and Tourism continuously promotes many of the country’s natural potential in tourism through various media: printed media, television and especially new media. However, there are challenges for the Indonesian tourism industry in facilitating entrepreneurship skills among the local people in East Nusa Tenggara. According to the Central Bureau of Statistics (2011), East Nusa Tenggara is considered as one of the poorest provinces in Indonesia where the economy is lower than the average, with a high inflation of 15%, and unemployment of 30%. This research is needed to explore further the phenomenon behind the above facts, aiming at examining the role of new media in facilitating entrepreneurship in the tourism industry in Komodo Island. The results of this study are expected to provide insights that can help local tourism in East Nusa Tenggara. Keywords: Tourism, Entrepreneurship, New Media

Effective Altruism

The effective altruism movement consists of a growing global community of people who organize significant parts of their lives around two key ideas, represented in its name. Altruism: If we use a significant portion of the resources in our possession—whether money, time, or talents—with a view to helping others, we can improve the world considerably. Effectiveness: When we do put such resources to altruistic use, it is crucial to focus on how much good this or that intervention is reasonably expected to do per unit of resource expended (for example, per dollar donated). While global poverty is a widely used case study in introducing and motivating effective altruism, if the ultimate aim is to do the most good one can with the resources expended, it is far from obvious that global poverty alleviation is highest priority cause area. In addition to ranking possible poverty-alleviation interventions against one another, we can also try to rank interventions aimed at very different types of outcome against one another. This includes, for example, interventions focusing on animal welfare or future generations. The scale and organization of the effective altruism movement encourage careful dialogue on questions that have perhaps long been there, throwing them into new and sharper relief, and giving rise to previously unnoticed questions. In the present volume, the first of its kind, a group of internationally recognized philosophers, economists, and political theorists contribute in-depth explorations of issues that arise once one takes seriously the twin ideas of altruistic commitment and effectiveness.

Internalizing And Externalizing Symptoms

In recent years, the field of clinical psychology has seen a growing movement toward the research and development of transdiagnostic treatments. Transdiagnostic approaches have the potential to address numerous issues related to the development and treatment of mental disorders. Among these are the high rates of comorbidity across disorders, the increasing need for efficient protocols, and the call for treatments that can be more easily disseminated. This chapter provides a review of the current transdiagnostic treatment approaches for the treatment of youth mental disorders. Three different types of transdiagnostic protocols are examined: mechanism-based protocols, common elements treatments, and general treatment models that originated from single-disorder approaches to have broader reach. A case study illuminates how a mechanism-based approach would inform case conceptualization for a client presenting with internalizing and externalizing symptoms and how a transdiagnostic framework translates into practice.
