This article presents an analysis of the main provisions of the Comprehensive Economic and Trade Agreement (CETA) signed by the government of Canada and the European Parliament at the end of 2016. In particular, the author analysed such aspects of the agreement as the abolition of customs tariffs, the introduction of common quality standards, access to the procurement market, modification of the system of investment disputes, etc. According to the results of the study, there was a mixed effect of the agreement for both Canada and the EU. For some sectors of the economies of the participating countries, the implementation of the CETA promises to create exceptional conditions for development, while for others the signing of a multilateral agreement is unprofitable or means losses. It should be noted that at the present stage the pros and cons of the СЕТА can be considered only at the theoretical level. It will be possible to draw objective conclusions about the impact of the multilateral trade agreement on the development of trade and economic relations between the countries only a certain time later after the ratification of the agreement by all parties. At the current stage of development of Canada-EU relations within the framework of the СЕТА, it can be noted that only the dynamic development and further improvement of the mechanisms of the multilateral agreement will make a trade and economic relations between the countries more open and transparent.

The Impact

For oil fields that are at a late stage of development, urgent tasks are the operational analysis of the development and optimization of the operating modes of injection wells. The demand for responsiveness often forces one to abandon the use of three-dimensional hydrodynamic models in favor of analytical ones such as CRMP. Using CRMP models allows you to quickly assess the trends in the impact of injection wells on producing wells and build reliable short-term forecasts for fluid production. Supplementing the traditional (single-phase) CRMP model with a water cut model also allows predicting oil production rates for producing wells and expands the capabilities of an operational analysis of the existing development system. In addition, an adequate water cut model allows using the CRMP model to solve the problem of optimizing the operating modes of the injection well stock. This article discusses the main known water cut models used in conjunction with the CRMP model, provides a brief analysis of their advantages and disadvantages. A new authorial mathematical model of water cut (“multi-characteristic model”) is proposed, which allows to establish the role of each injection well in changing the water content of the considered producer. An adaptation algorithm is also described, that is, the selection of unknown model coefficients implemented in Ariadna software (developed by Tyumen Petroleum Research Center LLC). The low computational complexity of the algorithm allows you to quickly simulate areas containing up to several hundred wells. The results of experiments on the use of a new mathematical model on a synthetic model of an oil reservoir are presented. The results of predicting water cut are compared with the results of previously known methods. The restrictions for using the new model, as well as directions for its development are indicated.

Innovative development of domestic enterprises and growth of their competitiveness is the most important task at the present stage of development of the country's economy. The purpose of this study is to develop methodological tools that assess the impact of strategic plans for innovative development of an enterprise on the level of its competitiveness. The hypothesis of the study is that the plans for innovative development of the enterprise have a positive impact on the level of competitiveness of the enterprise. The article shows that in modern conditions one of the main directions of increasing the competitiveness of any company is inextricably linked with the formation and use of innovative development systems at enterprises. An analytical review of the existing methods for evaluating the competitiveness of the enterprise is carried out; their advantages and disadvantages are determined. It is shown that there is currently no single universal approach to such evaluation. As a result, a reasonable choice was made in favor of a methodological approach that evaluates competitiveness in dynamics; the main indicators and algorithms used in this approach are presented. The method of assessing the stability of the competitive position of industrial enterprises based on their innovative activity using a number of innovative indicators and taking into account their possible growth in the financing and implementation of innovative projects is proposed. The competitiveness of the largest Russian Pipe Metallurgical Company in comparison with its leading domestic competitors in the period 2017-2019 was evaluated; the main problems and weaknesses in the company's activities that have a negative impact on its competitiveness are identified. An assessment of the innovative activity of the Pipe Metallurgical Company is performed, which shows that the company currently adheres to a strategy based on the introduction of improving innovations. Modeling of the dependence of the level of the competitiveness of the company on the indicators of its innovation activity is performed; the indicators that have the strongest impact are identified, namely: the coefficient of intellectual property security, the coefficient of innovative growth, and the coefficient of development of new products. An example of the implementation of an event aimed at increasing the company's innovation activity indicators and related to the commissioning of unique research equipment for the development of new threaded connections for pipes is given. Based on the projected outcomes of the event, the forecast level of competitiveness of the Pipe Metallurgical Company for the period up to the end of 2020 was determined.

The BRICS countries have a historical aspiration for global leadership, especially Russia and China, and other countries trying to have a position in the pyramid of international powers in the twenty-first century, especially Brazil, India and South Africa, they worked to unify their efforts, in order to achieve integration in the strategic action, activate its role in International affairs, ending American domination , and restructuring an international system that have an active role in its interactions.       The research hypothesis is based on the idea that the BRICS group, despite the nature of its economic composition and its long-term goals, but its political influence as a bloc, is greater than the proportion of its economic influence in restructuring the new international order. The BRICS group has the capabilities to reshape the international order, but disputes among some of its members represent a challenge to its future work. Its goals will not be achieved without teamwork. Third world countries, especially those that reject unipolarism, have regarded one of the pillars supporting multi-polarity, aiming of giving them freedom of movement in international relations. The ultimate goal of the BRICS is a political nature, as economic mechanisms are used to achieve political goals.

The Tonsillectomy in children or adults is an intervention commonly encountered in the ENT (Ear Nose and Throat) and Head and Neck surgeon practice. The current tendency is to perform this type of surgery in major ambulatory surgery centers. Two objectives are thus pursued: first of all, the increase of the patient quality of life through the reintegration into the family as quickly as possible and secondly, the expenses associated with continuous hospitalization are reduced. Any tertiary (multidisciplinary) sleep center must ensure the complete diagnosis and treatment (including surgery) of sleep respiratory disorders. Under these conditions the selection of patients and especially the implementation of the specific protocols in order to control the postoperative complications it becomes essential. The present paper describes our experience of tonsillectomy as treatment for selected patients with chronic rhonchopathy (snoring) and mild to moderate obstructive sleep apnoea. It was presented the impact of antibiotics protocols in reducing the main morbid outcomes following tonsillectomy, in our day surgery center. The obtained results can also be a prerequisite for the integrative approach of the patients with sleep apnoea who were recommended surgical treatment. Considering the wide range of therapeutic modalities used in sleep apnoea, each with its specific advantages and disadvantages, more extensive and multicenter studies are needed.

Technology in education is a global phenomenon affecting learners of all ages. The breadth and variety of available tools make it difficult to implement a standardized method for assessing the impact of technology on learning. The lack of a consensus on good and bad practices results in inconsistent application and mixed learning results.   This article takes a look at the adaptation of technology to education and examines the various tools used to enhance learning. We discuss the advantages and disadvantages of using technology, as well as review methodologies for evaluating the impact.   The essay concludes by identifying several problems with the way technology is evaluated and offers suggestions for further research to address those problems.

The Government Accounting Standards Board (GASB) recently released Statement No. 45, Accounting and Financial Reporting by Employers for Post-Employment Benefits Other Than Pensions and its companion Statement No. 43 for pooled stand-alone health care plans, which will profoundly affect American governmental finance. The goal of this article is to encourage governments to consider carefully a full range of options in funding and restructuring other post-employment benefits (OPEB). This article will review Statement No. 45's potential impact on governments and review existing disclosures in financial reports as well as bond offering statements. The article will discuss the statement's impact on budgets and governmental operations, including collective bargaining. Funding options under Statement No. 45 will be detailed, including the advantages and disadvantages of irrevocable trusts and OPEB bonds. The article will also discuss the impact of Medicare Part D subsidies received by governments, as well as the bond rating implications of policy decisions surrounding OPEB. As the largest government entities are just now implementing GASB Statement No. 45, estimates of the magnitude of unfunded OPEB liabilities are limited as are the strategies likely to be adopted to cover these obligations. This article offers a summary of the unfunded OPEB liabilities reported by states and major cities and suggests some measures for assessing the ability of these entities to address these costs.

The Impact

The growing demand for extensive and reliable structural health monitoring resulted in the development of advanced optical sensing systems (OSS) that in conjunction with wireless optical networks (WON) are capable of extending the reach of optical sensing to places where fibre provision is not feasible. To support this effort, the paper proposes a new type of a variable weight code called multiweight zero cross-correlation (MW-ZCC) code for its application in wireless optical networks based optical code division multiple access (WON-OCDMA). The code provides improved quality of service (QoS) and better support for simultaneous transmission of video surveillance, comms and sensor data by reducing the impact of multiple access interference (MAI). The MW-ZCC code’s power of two code-weight properties provide enhanced support for the needed service differentiation provisioning. The performance of this novel code has been studied by simulations. This investigation revealed that for a minimum allowable bit error rate of 10−3, 10−9 and 10−12 when supporting triple-play services (sensing, datacomms and video surveillance, respectively), the proposed WON-OCDMA using MW-ZCC codes could support up to 32 simultaneous services over transmission distances up to 32 km in the presence of moderate atmospheric turbulence.

The Impact

Even though climate change is having an increasing impact on tea plants, systematic reviews on the impact of climate change on the tea system are scarce. This review was undertaken to assess and synthesize the knowledge around the impacts of current and future climate on yield, quality, and climate suitability for tea; the historical roots and the most influential papers on the aforementioned topics; and the key adaptation and mitigation strategies that are practiced in tea fields. Our findings show that a large number of studies have focused on the impact of climate change on tea quality, followed by tea yield, while a smaller number of studies have concentrated on climate suitability. Three pronounced reference peaks found in Reference Publication Year Spectroscopy (RYPS) represent the most significant papers associated with the yield, quality, and climate suitability for tea. Tea yield increases with elevated CO2 levels, but this increment could be substantially affected by an increasing temperature. Other climatic factors are uneven rainfall, extreme weather events, and climate-driven abiotic stressors. An altered climate presents both advantages and disadvantages for tea quality due to the uncertainty of the concentrations of biochemicals in tea leaves. Climate change creates losses, gains, and shifts of climate suitability for tea habitats. Further studies are required in order to fill the knowledge gaps identified through the present review, such as an investigation of the interaction between the tea plant and multiple environmental factors that mimic real-world conditions and then studies on its impact on the tea system, as well as the design of ensemble modeling approaches to predict climate suitability for tea. Finally, we outline multifaceted and evidence-based adaptive and mitigation strategies that can be implemented in tea fields to alleviate the undesirable impacts of climate change.
