A Current

The treatment of urban solid waste represents, on the one hand, a current problematic drawing the intention of the authorities on their management and recovery through their recovery and recycling, and on the other hand, their gravity that they present on health and the environment. The purpose of this study is to provide solutions to the main questions regarding quantity, management principles, on which depend reliable management, landfilling techniques and their social, economic and environmental impacts. The methodology followed in this study is summarized by the following steps: review of the state of the art, field study and triage. The Batna landfill can, in its most unfavorable state, recycle 760,000 tons per year (between ores, paper, glass and plastic). Actually, recovery of recycled products accounted for only 23.89% for 2015.

Abstract Extraction of causal relations between biomedical entities in the form of Biological Expression Language (BEL) poses a new challenge to the community of biomedical text mining due to the complexity of BEL statements. We propose a simplified form of BEL statements [Simplified Biological Expression Language (SBEL)] to facilitate BEL extraction and employ BERT (Bidirectional Encoder Representation from Transformers) to improve the performance of causal relation extraction (RE). On the one hand, BEL statement extraction is transformed into the extraction of an intermediate form—SBEL statement, which is then further decomposed into two subtasks: entity RE and entity function detection. On the other hand, we use a powerful pretrained BERT model to both extract entity relations and detect entity functions, aiming to improve the performance of two subtasks. Entity relations and functions are then combined into SBEL statements and finally merged into BEL statements. Experimental results on the BioCreative-V Track 4 corpus demonstrate that our method achieves the state-of-the-art performance in BEL statement extraction with F1 scores of 54.8% in Stage 2 evaluation and of 30.1% in Stage 1 evaluation, respectively.

Workflow management promises a new solution to an age-old problem: controlling, monitoring, optimizing and supporting business processes. What is new about workflow management is the explicit representation of the business process logic which allows for computerized support. This paper discusses the use of Petri nets in the context of workflow management. Petri nets are an established tool for modeling and analyzing processes. On the one hand, Petri nets can be used as a design language for the specification of complex workflows. On the other hand, Petri net theory provides for powerful analysis techniques which can be used to verify the correctness of workflow procedures. This paper introduces workflow management as an application domain for Petri nets, presents state-of-the-art results with respect to the verification of workflows, and highlights some Petri-net-based workflow tools.

Despite the great interest that the scientific community has in quantum computing, the scarcity and high cost of resources prevent to advance in this field. Specifically, qubits are very expensive to build, causing the few available quantum computers are tremendously limited in their number of qubits and delaying their progress. This work presents new reversible circuits that optimize the necessary resources for the conversion of a sign binary number into two's complement of N digits. The benefits of our work are two: on the one hand, the proposed two's complement converters are fault tolerant circuits and also are more efficient in terms of resources (essentially, quantum cost, number of qubits, and T-count) than the described in the literature. On the other hand, valuable information about available converters and, what is more, quantum adders, is summarized in tables for interested researchers. The converters have been measured using robust metrics and have been compared with the state-of-the-art circuits. The code to build them in a real quantum computer is given.

The Aviation Group of the Ministry of Technology (formerly the Ministry of Aviation) is responsible for spending a large part of the country's defence budget, both in research and development on the one hand and production or procurement on the other. In addition, it has responsibilities in many non-defence fields, mainly, but not exclusively, in aerospace.Few developments have been carried out entirely within the Ministry's own Establishments; almost all have required continuous co-operation between the Ministry and Industry. In the past the methods of management and collaboration and the relative responsibilities of the Ministry and Industry have varied with time, with the type of equipment to be developed, with the size of the development project and so on. But over the past ten years there has been a growing awareness of the need to put some system into the complex business of translating a requirement into a specification and a specification into a product within reasonable bounds of time and cost.

The essential theme of this paper is to highlight the condition of health and hygiene in the British Bengal from the perspective of official documents and vernacular writings, with special emphasis on the journals and periodicals. The fatal effects of the epidemics like malaria and cholera, the insanitary condition of the rural Bengal and the cultivated indifference of the British Raj made the lives of the poor natives miserable and ailing. The authorities had a tendency to blame the colonized for their illiteracy and callousness, which became instrumental for the outbreak of the epidemics. On the other, in the late 19 th and the beginning of the 20th, the vernacular literature played the role of a catalyst in awakening health awareness, highlighting the issues related with ill health, insanitation and malnourishment. More importantly, it became an active link between the society and culture on the one hand, and health and people on the other. The present researcher wants to highlight these opposite trajectories of mentalities with a different connotation. The ideologies of the Raj and the native political aspirations often reflected in the colonial writings, where the year 1880 was considered as a landmark in the field of public health policies. On the other, the dichotomy between the masters and the colonized took a prominent shape during 1930s. Within these fifty years; the health of the natives witnessed many upheavals grounded on the social, economic and cultural tensions.

A phenomenon of extreme polarization between the Islamist and the secular camps characterizes the intellectual scene regarding social, economic, and political issues in the Arab-Islamic world. This is especially true with respect to women’s issues, which are a very hotly contested terrain. Understanding this reality clearly requires a historic overview to comprehend how this polarization occurred and map the debate between supporters of “modernity and contemporality” (al-hadatha wa-l-mu‘asara) on the one hand, and supporters of “tradition and authenticity” (al-turath wal-asala) on the other. Though this is not at the heart of our research, framing it in its historical context enables us to better understand the roots and origins of the problem, in order to map the debates and foresee future courses more clearly.

Architectural Survey

Today there are many publications or papers related with several graphic surveys of architectural heritage carried out using a variety of both traditional and cutting edge methods. Yet, the implementation of new graphical documentation systems, such as Automated Digital Photogrammetry, has introduced a fresh approach to dealing with architectural surveys by making them more accessible to the general public and, to a certain extent, increasing their usability (Garfella, Máñez, Cabeza, & Soler, 2014). The present study aims, on the one hand, to offer an overview of architectural survey systems and, on the other hand, to evaluate the differences in the degree of precision or accuracy between the latest state-of-the-art methods and the already well-established ones. This will enable us to examine the results obtained in this experiment to look for concordances and discrepancies between them that can be helpful when using such systems to deal with tasks in the future.

This article assesses the referendums in Hungary in 2004, 2008, and 2016 diachronically. The review is framed by two competing liberal parliamentary approaches to direct democracy: A useful democratic corrective to the distortions of particracy, or a risky option leading to tyranny of the majority? Rather than choosing sides, this article shows how the conundrum conceals another, more interesting question: Which are the constraints under which the liberal parliamentary viewpoint shifts from the one to the other? Theorizing on post-democracy and populism provides a provisional answer: A consensualized, “post-political” parliament is key, as this, in combination with widening social-economic disparities, incentivizes illiberal populist parties to harness referendums, which prompts liberal parliamentarianists to change their minds. The referendums in 2004, 2008, and 2016 in Hungary substantiate this suspicion. Taken together, they offer a step-by-step blueprint for how, in a thoroughly postpolitical situation, a referendum evolves into a perfect catalyst for populists on their road to power, enabling them with (a) agenda-setting; (b) an explosive emphasis on popular legitimacy; (c) arousing voluntarism, while luring opponents into campaigning for boycott and political apathy; (d) combining social equalitarianism with identarian protectionism, and most importantly; (e) bypassing parliament itself. This article is part of the special cluster titled Political Parties and Direct Democracy in Eastern Europe, guest-edited by Sergiu Gherghina.

Abstract The book under review serves as a significant contribution to the field of Trans-Himalayan linguistics. Designed as a vade mecum for readers with little linguistic background in these three languages, Nathan W. Hill’s work attempts, on the one hand, a systematic exploration of the shared history of Burmese, Tibetan and Chinese, and, on the other, a general introduction to the reader interested in obtaining an overall understanding of the state of the art of the historical phonology of these three languages. Whilst it is acknowledged that the book in question has the potential to be a solid contribution to the field, it is also felt that few minor issues can be also addressed.
