Nano particles are particles that exist on a nanometer scale. Nanoparticles exist in our surrounding either naturally or created by human activities. As per Commission of European Union (2011), a nano-object needs only one of its characteristic dimensions to be in the range of 1-100nm to be classed as a nanoparticle even if its other dimensions are outside that range. Nanoparticles have revolutionized the world through the introduction of a unique class of material and consumer products in many fields due to production of innovative materials and devices. Despite their unique benefits and utility in daily activities, this could result in undesirable changes in the environment and affect the workplace. Carbon-based nanoparticles, oxides of metals, and natural inorganic compounds can have biological effects on the environment and human health. This chapter deals with the nanoparticles and their mode of action in the environment.

Serat Cabolek shows the story which represents the Javanese mysticism, especially as told by the story of Dewaruci. The debate among Haji Amad Mutamakin and Ketip Anom about the spirituality of Dewaruci consist of synthesis Javanese and Islamic mysticism. Particularly, it is the emergence of Hinduism and Islam which shapes Javanese mysticism. Looking carefully at the dialogue and debate between Haji Mutamakin and Ketip Anom about the story of Dewaruci it shows that the concept of Javanese mysticism drawn to the fundamental themes such as what life is what to do in life, and how to live in a good life. Story of Dewaruci shows the significance of batin as an inner essence of a person. The goal of life is seeking “water of life” that is unity with the Divine. The Divine is not outside there and far from human. The mysticism of Java, therefore, is all about life in the world and human relation with himself, others, and the universe. It is about human activities in all their mundane activities and about human understanding of himself and the universe. Javanese mysticism lays in daily activities. It is in everyday life Javanese coming to the essence of life. These daily activities consist of all relations Javanese made the way of thinking Javanese understood and believed. All aspects become a mystic realm.  Keywords:Islamic Mysticism, Javanese Culture, Cultural Fusion

By detailed analyses of Polish and world statistics, the authors search for the answer if in fact,as some politicians and citizens claim, the world and in particular European Union and Polandare overcome by the wave of violence. Data gathered, among others, by Polish Public OpinionResearch Center (CBOS), Eurostat and United Nations Office on Drugs and Crime (UNOCD), aswell as anthropologists and police, clearly prove the opposite. Scientific comparisons concerningviolence over the centuries show that its scale drastically decreased and the world gets saferwith time. Statistical reports of the United Nations especially clearly indicate European Union(including Poland) as particularly peaceful region against the rest of the world, having the lowestmurder rates. Eurostat data confirm these results, also showing decrease in other crimes overthe years. Polish police data similarly prove existence of this trend and CBOS indicates thatit is reflected in increasing sense of security among Poles. In the second part of the article theauthors explain potential reasons for using such false slogans as “increasing wave of violence” bypoliticians and raising fear in voters as well as psychological mechanisms responsible for theirpotential effectiveness.

Background: According to the WHO report, around 4.07% of the world's population is visually impaired. About 90% of the visually impaired users live in the lower economic strata. In the fast moving technology, most of the invention misses the need of these people. Mainly the technologies were designed for mainstream people; visually impaired people always find an inability to access it. This inability arises primarily for reasons such as cost, for example, Perkins Brailler costs 80-248 dollars for the simple purpose of Braille input. Another major reason is the hassle of carrying the big equipment. Objective: Keeping all this in mind and making technology as their best friends, MAGIC-1 has been designed. The goal is to provide a solution in terms of an application, which helps the visually impaired user in their daily life activities. Method: The proposed solution assists visually impaired users through smart phone technology. If visually impaired users ever wished to have a touched guide into a smart phone, MAGIC-1 has the solution that consolidates all the important features in their daily activities. Results: The performance of the solution as a whole and its individual features in terms of usability, utility and other metrics, etc. has been tested with sample visually impaired users. Moreover, their performances in term of Errors per Word and Words per Minute have been observed. Conclusion: MAGIC-I, the proposed solution works as an assistant of visually impaired users to overcome their daily struggles and stay more connected to the world. A visually impaired user can communicate via their mobile devices with features like eyes free texting using braille, voice calling etc. They can easily take help in an emergency situation with the options of SOS emergency calling and video assistance.

The issues of wastewater treatment and the reuse of water are of great importance, especially in areas where the shortage of conventional resources is a structural problem, as it is in the case of Spain. Wastewater reuse is a valid mechanism to avoid problems derived from droughts and water scarcity. It allows access to water resources in areas with water restrictions and to prevent futures scenarios, due to it being expected that water consumption will double by 2050 over the world. Thus, the likelihood that this unconventional, strategic resource would become scarce is unquestionable, particularly in cases where water planning and exploitation systems prioritize the preservation, protection, and improvement of water quality, as well as the sustainable and efficient use of natural resources. This paper shows how wastewater treatment and reuse are linked, as the reuse of wastewater is associated with a previous regeneration, and both of them are essential tools for maximizing environmental outcomes, as called for in the European Union Directives.

Abstract Discontentment is growing such that governments, and notably that of China, are increasingly providing subsidies to companies outside their jurisdiction, ‘buying their way’ into other countries’ markets and undermining fair competition therein as they do so. In response, the European Union recently published a proposal to tackle such foreign subsidization in its own market. This article asks whether foreign subsidies can instead be addressed under the existing rules of the World Trade Organization, and, if not, whether those rules allow States to take matters into their own hands and act unilaterally. The authors shed light on these issues and provide preliminary guidance on how to design a response to foreign subsidization which is consistent with international trade law.

Abstract The catalytic power of organic compounds in general has up to the present time been studied much less extensively than that of inorganic compounds. For about the last ten years, however, the first author has, in collaboration with a number of his students, attempted to fill this gap, though so far efforts have been confined to explaining the mode of action of natural enzymes by means of comparative experiments with organic catalysts. As a result of this work, a theory based on experimental facts has been developed to explain in a satisfactory way the action of enzymes. The other phase of organic catalysis is, strictly speaking, a technical problem. Why for instance should it not be practicable to utilize organic catalysts more extensively than heretofore in industry? If this problem is to be attacked, it seems reasonable to start with the particular industry which already uses organic catalysts to the greatest extent. This is, of course, the rubber industry. The important accomplishments of the chemical industry with respect to the development of vulcanization accelerators is already common knowledge, and the important task at present is not simply to increase the great number of accelerators already known. A problem of more practical value would seem to be to study the mechanism of the acceleration of vulcanization, about which relatively little has been known heretofore.
