In cloud quantum computing, a classical client delegate quantum computing to a remote quantum server. An important property of cloud quantum computing is the verifiability: the client can check the integrity of the server. Whether such a classical verification of quantum computing is possible or not is one of the most important open problems in quantum computing. We tackle this problem from the view point of quantum interactive proof systems. Dr Tomoyuki Morimae is part of the Quantum Information Group at the Yukawa Institute for Theoretical Physics at Kyoto University, Japan. He leads a team which is concerned with two main research subjects: quantum supremacy and the verification of quantum computing.

Institute of the Lithuanian Language At the beginning of the 19th century, the financial possibility to establish a department of Eastern languages at one of the oldest universities in Eastern Europe, Vilnius University, appeared. Turkish was among the Eastern languages that were expected to be taught. The intensive preparation of lecturers was started. Unfortunately, the ambitious plans were destined to never become reality; in 1832 the university was closed. Nevertheless, over the following two centuries the Turkic direction did not disappear; in one form or another it surfaced and retained its vitality. There was a sympathetic environment: Tartars and Karaims—both Turkic ethnic groups—began settling in the Grand Duchy of Lithuania in the 14th century. Vilnius University was the cradle of many famous Orientalists who maintained Turkic research by their activities. In such a way, two main research subjects appeared: Kitabistik and the Karaim language. In this article, the origin problems, development and prospects of Turkic research will be examined.

The methyl violet dye as the main research subjects. The concentration of H2O2, ferrous ion concentration, pH value and the type of dyes and so on be research the influence on the rate. The result shown: the greater dose of H2O2, the greater removal of methyl violet dye. when the dose of H2O2reach to a certain amount, keep increase the dose , but the increase was not obvious. In a certain concentration range, when the higher concentration of ferrous ions, the higher degradation rate of methyl viologen.When more than the certain concentration, the degradation rate began to decline. The removal efficiency is better when the ratio of ferrous ions and H2O2is 1:10..A large removal rate is controlled in the temperature of 20 to 60 as well as the pH is from 3 to 5. After changing the type of dye,beside the Alizarin Red,the removal of Methylene blue, Rhodamine, methyl violet are all high.

The MDGs ended 2015, and it is continued by the SDGs until 2030. The third Goal for the "Good Health and Well Being" indicator reduced MMR. Indonesia becomes the highest country for Maternal Mortality Rate in the ASEAN region. MMR in Indonesia 2012 reached 359,000 /100,000 KH meanwhile MM in East Java in 2015 reached 89.6 / 100,000 KH. In Jombang Regency in 2017 there were 28 maternal deaths. The action plan for reducing MMR is called GEBRAK program which began in 2016. The aim of the study was to evaluate the implementation of GEBRAK program as an effort to reduce MMR and IMR in Banjardowo Jombang Regency. This research employed qualitative study with in-depth interviews and documentation. The main research subjects were 8 teams (2 students, 2 midwives, 3 cadres, and 2 pregnant women). Supporting informants were 2 people (KGM Head Office and Head of Midwifery Diploma Program). Data was collected by in-depth interviews. Processing and analysis of data used content analysis. The results of the study showed that there was a program implementation policy in Health Office of East Java Province; complete facilities were available, human resources were community based team; budgets from the central and regional government was available; there was no similar, standardized and legalized SOPs; there was no reports written to Jombang Health Office, and the babies and mothers were healthy and safe. Jombang District Health Office is expected to arrange GEBRAK SOP with health education institutions, authorizes SOPs, disseminates SOPs, and monitors evaluations.

Waste is still a problem in Indonesia. The increase in population causes the volume of waste to continue to grow, in Karangmangu Village, Banyumas Regency. Data on the increase in the volume of waste in Banyumas Regency reached 21.4%. The volume of inorganic waste is greater than organic waste because Karangmangu Village is a tourism buffer area in Baturraden. This study aimed to describe the knowledge, attitudes, and practices of cadres in the management of inorganic waste. The method used was descriptive qualitative. The research subjects were obtained using a purposive technique by conducting interviews with cadres as the main research subjects, midwives, and supporting informants. Data were collected through in-depth interviews and documentation. The results showed that the cadres had understood the definition, types, management, and negative impacts of inorganic waste. Based on their attitudes, the cadres consider the case of handling inorganic waste to be not optimal. In practice, they have sorted inorganic waste, managed a waste bank, made bricks, and produced handicrafts. Strategies to overcome obstacles in waste management are optimizing the facilities and infrastructure for the procurement of waste banks, as well as training more people to make handicrafts and market handicraft products. This study concludes that the presence of village cadres is able to increase public awareness in waste management.

We present surveys and related studies of active galaxies carried out at the Byurakan Astrophysical Observatory (BAO). This was one of the main research subjects at BAO during many years, since mid-1950s, when Viktor Ambartsumian suggested the hypothesis of the activity of the galactic nuclei. A number of surveys and searches for Active Galactic Nuclei (AGN) and other active galaxies were accomplished during 1960s-1980s. Since mid-1990s, our research group carried out new surveys and studies of active galaxies based on the First Byurakan Survey (FBS or Markarian Survey) and then a number of others. Here we also present the recent results of studies on active galaxies (both AGN and Starbursts) by the Extragalactic group of the Byurakan Astrophysical Observatory (BAO) Research Department “Astronomical Surveys”. These studies are characterized by multiwavelength approach to statistical analysis of large amount of data obtained in different wavelengths; from X-ray to radio. A fine classification scheme for active galaxies has also been suggested.

This text begins with a concern related to teacher education which will focus on early childhood education, specifically in regards into the sciences and knowledge relating to the axes undertaken to frame the curriculum of the first stage of basic schooling as nature, culture and society. Science for young children should be considered as the foundation of all later development and is clear that it is not understood as it should be. But now, it is being more discussed taking account that these children have their development in a holistic perspective (Johnston, 2009; Johnston & Tunnicliffe, 2008). It should be noticed that the approach of knowledge related to science in Early Childhood Education, discussed in this text, does not take place in an isolated way, should be developed on a proposal mainly integrating the different fields of knowledge, to explore, in the articulation of knowledge, the wealth of exploitation and appropriating the world by the children. According to Johnston (2011) science teaching should be encouraged in the early years, aiming at reaching a holistic sense, that is, seeking not only understanding the scientific concepts but also developing attitudes and abilities related to them. Thus, the understanding of scientific concepts is closely related to both the development of knowledge in other areas such as geography, history and mathematics and to the social skills, such as collaboration, cooperation, etc and attitudes such as enthusiasm, initiative, curiosity etc.

Object Of Study

For some time, business improvement districts (BIDs) have entered into the discourse and practice of academics and urban planners. This model for town centre revitalization was created in North America, whose success has led to its transfer to a growing number of countries. This evolution highlights the importance of BIDs as an urban planning practice, as well as an object of study for academics interested in new models for intervening in central urban areas. BIDs are public–private partnerships, framed within an entrepreneurial logic of urban management that aims to increase the cities’ competitiveness. In this article, we aim to unfold the main research subjects of the literature focused on BIDs. We develop a systematic review for said endeavor, resorting to the established PRISMA protocol. After the screening and analysis of selected articles, four main research subjects were documented: (i) urban governance; (ii) urban policies: mobility and transfer; (iii) activities/axis of intervention; and (iv) types of BIDs/places of intervention. The selected literature enhances the contradictory nature of BIDs, ranging from the economic revitalization of city centres to the occasional exclusionary stance, in which it is developed. Our analysis also points to the important role of different actors in all stages of the policy transfer and implementation.
