Improved understanding of proppant embedment behavior under reservoir conditions: A review study

Water is gradually becoming scarce in Afghanistan like in many other regions of the globe. The objective of this study was to evaluate the spatial changes in the availability and sustainability of water resources in Afghanistan. The Terrestrial Water Storage (TWS) data of the Gravity Recovery and Climate Experiment (GRACE) satellite obtained from three different institutes, having 1° × 1° spatial resolution for the period 2002–2016 was used for this purpose. Sen’s slope method was used to assess the rate of change, and the Modified Mann–Kendall test was used for the evaluation of the significance of trends in TWS. After, the concept of reliability–resiliency–vulnerability (RRV) was used for assessing the spatial distribution of sustainability in water resources. The results revealed a significant decrease in water availability in the country over the last 15 years. The decrease was found to be highest in the central region where most of the population of the country resides. The reliability in water resources was found high in the northeast Himalayan region and low in the southwest desert; resilience was found low in the central region, while vulnerability was found high in the south and the southeast. Overall, the water resources of the country were found most sustainable in the northeast and southwest and least in the south and the central parts. The maps of water resource sustainability and the changes in water availability produced in the present study can be used for long-term planning of water resources for adaptation to global changes. Besides, those can be used for the management of water resources in a sustainable and judicious manner.

The article discusses the question of the possibility of the business community to implement mechanisms for the development of its structure. The authors show that in the process of historical transformation are implemented opportunities for market entry and process of improvement activities. The authors show that every company can produce a range of innovative products and its innovative principles transform of striving for improvement in the need to innovate. The subject of research is itself innovative activity of the organization, and the possibility of its integration in market conditions.
The novelty of this study is the assumption that the innovation activity of the enterprise does not depend on the amount of goods produced and the number of shipped innovative products. The main indicator is the amount of revenue from goods that are produced on the basis of a new technological cycle. In the course of the work are analyzed the statistics and formed the algorithmization of actions to increase the share of innovative products
The authors show and this is the basis for further research that the advancement and increase of the share of innovative products determines the possibility of development of a qualitatively new setting and identifies opportunities for technological and, consequently, the social capital of a certain territory.

For several millennia the water resources had been the key issue for the development of Central Asia They were used for the development of agriculture, water supply, fishery, navigation, and, generally, the national economies They were also natural barriers for protection from enemies With the economic development and population growth, the water had become the most deficit resource Taking into consideration the above, the history of water relations in Central Asia was fraught with acute struggle for water that was always the most vital resource in such arid intercontinental region located far from seas and oceans

The Caspian Sea and its Kara-Bogaz-Gol Bay play an important role in different branches of the economy of Turkmenistan Turkmen shores of the Caspian Sea have a big potential as a national and international resort area which is developing quickly The Caspian Sea water (after desalination) is an immense source of potable and technical water for the country, living in the desert conditions This chapter describes the main geological, physical, chemical, biological, and climatic characteristics of this largest enclosed water body in the world Special attention is given to the Kara-Bogaz-Gol Bay, which is located in the territory of Turkmenistan and during a century played a key role in the chemical industry of the Turkmen Soviet Republic and today in Turkmenistan

The Caspian Sea and Kara-Bogaz-Gol Bay

This book takes together and systematizes the information about the pipeline projects that were accomplished or discussed beginning from the late 1980s to the mid-second decade of the twenty-first century in the Black Sea and Caspian Sea regions. Using the abundant data available on this issue, the authors investigated the state and perspectives of oil and gas production in the countries of the Black Sea and Caspian Sea regions and described numerous projects, each of which made its own weighty contribution into the development of the pipeline transport in this part of the world. This book is intended for specialists in international relations in the field of energy, regional relations, for experts studying the socioeconomic and political development of the countries of the Black Sea and Caspian Sea regions.
