The development and results of electrochemical studies in the field of sulfide flotation are discussed and generalized. The role of oxygen and redox transitions on the sulfide surface in the kinetics of sorption of thiol collectors and the formation of hydrophobic layer on the surface of sulfide minerals is shown. The regularities of autooxidation of thiols catalyzed by cobalt phthalocyanines are described. The effect of inhomogeneity of mineral surface on the wettability of minerals is considered. Theoretical aspects and practical potentialities for enhancing the contrast of physicochemical and flotation properties of sulfides and the reagentless methods for optimization of flotation of polymetallic and gold-bearing sulfide ores are considered. The monograph is intended for the researchers and engineers engaged in the flotation and hydrometallurgy.
An innovative investment approach that takes the actions of the U.S. Congress into consideration Historical research indicates that, more often than not, when Congress is in session there is a negative effect on equities markets (the «Congressional Effect») due possibly to investor uncertainty surrounding government action or inaction as well as the unintended consequences of Congressional legislative initiatives on the stock market. Author Eric Singer, a financial professional with over twenty-five years of experience, is an expert on this phenomenon, and with this new book he shares his extensive insights with you. Trade the Congressional Effect skillfully details how you can profit from Congress's impact on the stock market. Along the way, it puts this approach in perspective and gives you all the tools you'll need to profitably incorporate it into your investing endeavors. Singer walks you through the process of trading the Congressional Effect and provides practical guidance regarding the possible pitfalls and opportunities you'll face each step of the way. Addresses why it is better to invest while Congress isn't in session Reveals exactly what the Congressional Effect encompasses and why it occurs Written by Eric Singer, one of the first people to publicly document the general effect of Congress on daily stock prices Supported by over forty-five years of real world data, the Congressional Effect has proven profitable to those who know how to use it. This timely guide will show you exactly what it takes to make this phenomenon work for you.

Dealing with vibrations and waves, this text aims to provide understanding of the basic principles and methods of analysing various physical phenomena. The content includes the general properties of propagation, a detailed study of mechanical (elastic and acoustic) and electromagnetic waves, propagation, attenuation, dispersion, reflection, interference and diffraction of waves. It features chapters on the effect of motion of sources and observers (both classical and relativistic), emission of electromagnetic waves, standing and guided waves and a final chapter on de Broglie waves constitutes an introduction to quantum mechanics.
The study contributes in analytical description of spatial diffusion of fertility, in particular, influenced by labour movements of people between places of residence and work. It is assumed that the labour market has externality on the marriage market due to commuting, which, in turn, affects fertility. A model of spatial diffusion of fertility is based on assumption of global and local spillover effects. The global spillover effect, as shifts in fertility norms, is motivated by increasing variance of social interactions of an individual, when places of work and residence are different. One local spillover effect is in response to flows of earnings across space. Another mechanism is related to expected changes in probabilities to find a partner affected by differences in day and night population. The analytical model, in which the effects on fertility of the cited spillovers are decomposed, is constructed in the paper on the base of a model of the demand for children, spatial stock-flow model of a market, and a matching model with a sex imbalance or spatial mismatch as the probability of matching. Three sex imbalances, namely of night-, day-time population and an adjusted to sex imbalance of commuters to residents are empirically tested. Empirical evidence on municipal Swedish data for the period 1994–2008 does not provide any strong evidence of spatial diffusion of fertility. However, there are externalities of labour mobility on fertility due to changes of gender structure of population.
This paper extends research on the relation between crime and happiness by investigating the impact of serious and less serious crime (i.e. incorrect behavior) on subjective wellbeing using a representative survey of the Dutch adult population in 2008. We also control for variables reflecting trust, health and social norms, in addition to standard demographic and socio-economic characteristics. We find that people who feel healthy, have more trust in others and have higher social norms are in general happier. We find evidence of an indirect effect of victimization on well-being via trust, health and social norms. The remaining effect of victimization on well-being, keeping trust, social norms, and health constant, is quite weak.
What does with the person the power and what are the fruits of efforts of the person in power? Who actually uncompromisingly counteracts the authorities and whether a complete victory of one of the parties is possible? What is the primary source of the development of society? Is not it curious to take a look at all this from the highest bell tower, if thou is not too lazy to climb up on it!?
