The subject of the research is the ecological situation in 12 selected cities: Bratsk, Krasnoyarsk, Lipetsk, Magnitogorsk, Mednogorsk, Nizhniy Tagil, Novokuznetsk, Norilsk, Omsk, Chelyabinsk, Cherepovets and Chita. The purposes of the work are to analyze the structure, subjects, goals and objectives of the project “Pure Air” that is a part of a large-scale national project “Ecology”, as well as to evaluate the concrete character level of the proposed actions and their prospective effectiveness. In the course of the research only open sources of information, data of statistical organizations and relevant Ministries Departments were used. A conclusion is made about the large scale of the declared investment programmes of industrial enterprises (including heat-andpower enterprises) that will highly likely be fulfilled as they are carried out at the sole cost and expense of the enterprises. It is concluded in the article that complex plans to reduce emission of pollutants appear to be quite consequent and well-developed and they should lead to the achievement of the main project goal that is to reduce the total emission volume by at least 20%, and to change the load status of the cities under consideration from “very high” to “high”. If the majority of the actions planned is realized, the ecological situation in the selected cities will change significantly, which will allow to use the obtained experience in other Russian cities.

The most promising and innovative alternative to biodiesel production is presented by the algae (micro and macroalgae), which have been classified by scientists as a source of third generation biofuels. The large-scale production of biodiesel from microalgae and macroalgae bioethanol production will happen much faster than you think. It is believed that its full commercialization is possible within a few years, and with a competitive price compared to diesel produced from petroleum, the same occurring for bioethanol. The use of seaweed as a feedstock for the production of biofuels has been seen as a less environmentally impactful as the biomass produced on the continent and its potential is very high. Several groups in Latin America (Brazil, of course) are studying micro and macroalgae not only for biofuels production (biodiesel, bioethanol, biohydrogen) but also to do wastewater treatment. This paper will discuss the presentations done in four annual courses (2010, 2011, 2012, 2013) promoted by the Biotechnology Brazilian Argentine Center, BBAC, and offered to fellowships (sixteen per year), from Brazil, Argentina, Colombia, Paraguay and Uruguay. Arthrospira (Spirulina) platensis was chosen as a cyanobacteria model in the courses, due to its feasibility of cultivation, many publications about the subject and the existence of strains isolated in Brazil.

The paper examines a specific model of wage-setting evolved in Russia under transition. Using new survey data author reveals paradoxical characteristics of wage-setting mechanisms at Russian industrial enterprises: very high union and collective agreement coverage; nearly unilateral control of managers over wage determination; close correlation between earnings and enterprises' performance; voluntary utilization of wage standards established by the state. The special section explores effects of fulfilling a new provision stipulated for by the recently adopted Labor Code to raise minimum wage to the subsistence minimum level. The author concludes that wage-setting in the Russian labor market is at odds with a textbook competitive model and poorly fits into many other sophisticated theoretical schemes (such as labor-managed firms, bargaining models etc.).

AbstractThe article presents the results of the review of the empirical literature regarding the impact of quantitative easing (QE) on emerging markets (EMs). The subject is of interest to policymakers and researchers due to the increasingly larger role of EMs in the world economy and the large-scale capital flows occurring after 2009. The review is conducted in a systematic manner and takes into consideration different methodological choices, samples and measurement issues. The paper puts the summarized results in the context of transmission channels identified in the literature. There are few distinct methodological approaches present in the literature. While there is a consensus regarding the direction of the impact of QE on EMs, its size and durability have not yet been assessed with sufficient precision. In addition, there are clear gaps in the empirical findings, not least related to relative underrepresentation of the CEE region (in particular, Poland).

Climate change and its impact on water resources is the problem of the times. Therefore, this study is concerned with the subject of climate change and its impact on the water ration of the grape harvest in Diyala Governorate. The study was based on the data of the Khanaqin climate station for the period 1973-2017, (1986-2017) due to lack of data at governorate level. The general trend of the elements of the climate and its effect on the water formula was extracted. The equation of change was extracted for the duration of the study. The statistical analysis was also used between the elements of the climate (actual brightness, normal temperature, micro and maximum degrees Celsius, wind speed m / s, relative humidity% The results of the statistical analysis confirm that the water ration for the study area is based mainly on the X7 evaporation / netting variable, which is affected by a set of independent variables X1 Solar Brightness X4 X5 Extreme Temperature Wind Speed ​​3X Minimal Temperature and Very High Level .

Points Of View

In  densely populated areas, such as Flanders, serious conflicts arise due to the  afforestation of agricultural lands. Roughly speaking, three sectors are  involved: agriculture, forestry and nature conservation. These groups do not  always share the same points of view. But even within the different sectors  there are several subgroups with their own interests and approaches.  Generally speaking, agriculture is strongly opposed, forestry has a  relatively diversified meaning, whereas nature conservation is either opposed  or in favour, depending on the region's biological value.     The policy in this matter is not forest friendly. Legislation strongly  hampers the afforestation of agricultural lands. Moreover the subject leads  to a series of ecological problems, which have not really been considered up  to now.

Public-private partnership (PPP) in the conditions of the set strategic tasks by the President of the Russian Federation until 2030 can become one of the sources of attracting financial resources for implementation of the large-scale projects. In this regard, it is relevant to systematize the forms of PPPs and the scope of their application. Based on a study of different views on the essence of PPP, as well as taking into account the development of public administration in Russia, the author proposed the use of public-public-private partnership as a form of development of cooperation between the state, private business and society. The polyformism of PPPs is reflected in the presented classification. Based on the analysis of PPP development in the regional context, hypothesis on the correlation between the level of PPP and the socio-economic development of the subject of the Russian Federation was confirmed.

The Subject

In an ideal world, assessment should be synonymous with effective learning and reflect the intricacies of the subject area. It should also be aligned with the ideals of education: to provide equitable opportunities for all students to achieve and to allow both appropriate differentiation for varied contexts and students and comparability across various contexts and students. This challenge is made more difficult in circumstances in which the contexts are highly heterogeneous, for example in the state of Queensland, Australia. Assessment in music challenges schooling systems in unique ways because teaching and learning in music are often naturally differentiated and diverse, yet assessment often calls for standardization. While each student and teacher has individual, evolving musical pathways in life, the syllabus and the system require consistency and uniformity. The challenge, then, is to provide diverse, equitable, and quality opportunities for all children to learn and achieve to the best of their abilities. This chapter discusses the designing and implementation of large-scale curriculum as experienced in secondary schools in Queensland, Australia. The experiences detailed explore the possibilities offered through externally moderated school-based assessment. Also discussed is the centrality of system-level clarity of purpose, principles and processes, and the provision of supportive networks and mechanisms to foster autonomy for a diverse range of music educators and contexts. Implications for education systems that desire diversity, equity, and quality are discussed, and the conclusion provokes further conceptualization and action on behalf of students, teachers, and the subject area of music.

ABSTRACT Perturbation theory is an indispensable tool for studying the cosmic large-scale structure, and establishing its limits is therefore of utmost importance. One crucial limitation of perturbation theory is shell-crossing, which is the instance when cold-dark-matter trajectories intersect for the first time. We investigate Lagrangian perturbation theory (LPT) at very high orders in the vicinity of the first shell-crossing for random initial data in a realistic three-dimensional Universe. For this, we have numerically implemented the all-order recursion relations for the matter trajectories, from which the convergence of the LPT series at shell-crossing is established. Convergence studies performed at large orders reveal the nature of the convergence-limiting singularities. These singularities are not the well-known density singularities at shell-crossing but occur at later times when LPT already ceased to provide physically meaningful results.

Of Greece

Simple formulas for estimating annual actual evapotranspiration (AET) based on annual climate data are widely used in large scale applications. Such formulas do not have distinct compartments related to topography, soil and irrigation, and for this reason may be limited in basins with high slopes, where runoff is the dominant water balance component, and in basins where irrigated agriculture is dominant. Thus, a simplistic method for assessing AET in both natural ecosystems and agricultural systems considering the aforementioned elements is proposed in this study. The method solves AET through water balance based on a set of formulas that estimate runoff and percolation. These formulas are calibrated by the results of the deterministic hydrological model GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) for a reference surface. The proposed methodology is applied to the country of Greece and compared with the widely used climate-based methods of Oldekop, Coutagne and Turk. The results show that the proposed methodology agrees very well with the method of Turk for the lowland regions but presents significant differences in places where runoff is expected to be very high (sloppy areas and areas of high rainfall, especially during December–February), suggesting that the proposed method performs better due to its runoff compartment. The method can also be applied in a single application considering irrigation only for the irrigated lands to more accurately estimate AET in basins with a high percentage of irrigated agriculture.
