Water Conservation and Wastewater Treatment in Brics Nations
Water Conservation and Wastewater Treatment in BRICS Nations: Technologies, Challenges, Strategies, and Policies addresses issues of water resources—including combined sewer system overflows—assessing effects on water quality standards and protecting surface and sub-surface potable water from the intrusion of saline water due to sea level rise. The book's chapters incorporate both policies and practical aspects and serve as baseline information for future adaption plans in BRICS nations. Users will find detailed important information that is ideal for policymakers, water management specialists, BRICS nation undergraduate or university students, teachers and researchers.
Equation of state, compressibility, and vibrational properties of brucite over wide pressure and temperature ranges: Atomistic computer simulations with the modified ClayFF classical force field
The behavior of brucite over wide ranges of temperatures and pressures is of great interest
for fundamental geochemistry and geophysics. Brucite layers and their octahedral Mg(OH)6 structural
units constitute an important structural part of layered dense magnesium hydrous silicates
(DMHS), which play a major role in mineral equilibria controlling water balance in the subduction
zones of the upper mantle. The ClayFF force field was originally developed for atomistic computer
simulations of clays and other layered minerals and their hydrated interfaces. The crystallographic
parameters of brucite at 25 C and 1 bar were used, among several others, to develop the original
ClayFF parametrization. Its new recent modification, ClayFF-MOH, can more accurately account for
the bending of Mg–O–H angles in the brucite structure, and it was used here to test the applicability
of this simple classical model over very wide ranges of temperature and pressure well beyond the
range of its original implementation (up to 600 C and 15 GPa). The pressure and temperature
dependencies of brucite crystallographic parameters, the compressibility of the crystal lattice, the
coefficients of thermal expansion, and the vibrational spectra were calculated in a series of classical
molecular dynamics simulations using the ClayFF-MOH model and compared with a diverse set
of available experimental data, including X-ray diffractometry, neutron scattering, IR and Raman
spectroscopy. These new results demonstrated that ClayFF-MOH, as simple and approximate as it is,
can be quite accurate in predicting many mineral properties at subduction zone conditions, which
greatly expands the area of its applicability.

Development cycles of cities in the Siberian North
This chapter describes the development cycles of cities in the Siberian North. These cycles are typically connected to the boom-and-bust cycles in associated natural resource development. I discuss the oil and gas cities of the Khanty-Mansiysk Autonomous Okrug “Ugra,” the Yamal peninsula, the Yenisei North (Igarka, Dudinka), and Dickson on the northern sea route. Using ethnographic interviews, I analyze the characteristics of different phases of development and changes in the social sphere and the mood of citizens across these phases and geographic areas. I discuss on the peculiarities of urban development in Siberia based on different resource exploitation histories and the possibilities of moving to a post-raw material stage of development in the Siberian North.

EXPLORING ASSOCIATIONS BETWEEN PARKING OCCUPANCY RATE AT RESIDENTIAL ESTATES AND SPATIAL CHARACTERISTICS. THE CASE OF YEKATERINBURGFinancial losses due to low demand for parking spaces in garages at residential estates is a key motivation for this research. The purpose of this paper in particular is to statistically explore the relationship between parking occupancy rates and various factors on transport supply, characteristics of location and the building. The occupancy rate of parking was measured as the ratio of actual number of cars to total number of parking spaces. The fieldwork on counting occupied parking spaces was conducted 2 times per day during a week on a sample of 13 locations in different areas of a 1.4-million Yekaterinburg city in Russia. 4700 observed parking spaces give sample size of 173 records. Statistical analysis shows that the crow-fly distance to the city center as well as the number of public transport stops are strongly associated with occupancy rate for parking. Also, occupancy rate is much more affected by the type of parking ownership. Private owning means purchase of a parking space or renting it while public ownership suggests free access. So private parking means a 45% decline in occupancy compared to the public parking regime. Research provides empirical results and some theoretical underpinnings are also highlighted.

About the School
Vysokovsky Graduate School of Urbanism (GSU) is a learning and research division of the Faculty of Urban and Regional Development of HSE University. Founded in 2011, the School takes a multidisciplinary approach towards studying and planning modern cities, using the excellent foundation that one of Russia’s top universities has formed in the humanities and socioeconomics. The School’s mission is to create a centre in Russia for learning and research in urban studies and urban planning. It is envisioned that this centre will respond to the needs of the 21st century city and the corresponding era of megacities that are home to tens of millions of people with diverse interests and aspirations.
