AbstractPorous and fractured aquifers exist in the area of Hurghada, Eastern Desert of Egypt, whose recharge processes through the common flash floods are not identified. Hydrochemical parameters, stable isotopes 18O, 2H and tritium in floodwater and groundwater were applied in the area subject to study. Additionally, He isotopes were investigated in the deep wells in the faulted zone at the Abu Shaar Plateau. 3H activity in all sampled points lies below the detection limit excluding a recent recharge component in groundwater. However, the hydrochemical ratios and the stable isotope signature confirm that the shallow wells and springs (Red Sea Hills group) are being recharged from modern precipitation. The hydrochemical parameters of the deep wells at the Abu Shaar Plateau (coastal plain group) confirm another origin for the ions rather than the modern precipitation. Together with the 18O and 2H values, the Br/Cl ratio of this group confirms the absence of seawater intrusion component and the role of the fault as a hydraulic barrier. These 18O and 2H values deviate from the GMWL confirming an evaporation effect and colder infiltration conditions and reveal strongly a possible mixing with the Nubian Sandstone in the region. The 3He/4He ratio confirms a mantle contribution of 2% from the total He components.

An extensive survey of well water used on swine farms in Saskatchewan was undertaken as a first step in trying to clarify the apparent disagreement between field and laboratory observations with respect to water quality and pig performance. One hundred and thirty-five wells throughout the province were sampled for a comprehensive chemical analysis; at the same time, a questionnaire concerning pig performance and perceptions of water quality was administered to the well owners. Concentrations of sulphate and total dissolved solids (TDS) were above levels recommended in Canada for livestock in 25.0% and 7.4%, respectively, of the wells. Sodium and chloride were also high in many wells. High levels of trace metals were not observed. Three major groups of wells were discerned: low saline, shallow wells with sulphate being the major contributor to TDS, high saline, deeper wells, also with sulphate being the major contributor to TDS, and high saline, deep wells with sodium the major contributor to TDS. The incidence of minor to moderate scouring in weanlings, as reported by producers, was directly related to TDS, magnesium, calcium and sulphate, but bore no relationship to sodium. The common occurrence of high sulphate water and its apparent link to on-farm scouring in weanlings indicate that sulphate is probably the ion of most concern to Saskatchewan hog producers. Key words: Well water quality, swine, sulphate, scouring

This article focuses on the main contemplative principles of the ‘Heart Essence’ (sNying thig), a Tibetan Buddhist tradition that is characterized by a vision of non-duality and primordial wholeness. Due to this vision, which asserts an original reality that is not divided into perceiving subject and perceived object, the ‘Heart Essence’ advocates a contemplative practice that undermines the usual intuitions of temporality and enclosed selfhood. Hence, unlike the common principles of intentional praxis, such as deliberate concentration and gradual purification, the ‘Heart Essence’ affirms four contemplative principles of non-objectiveness, openness, spontaneity and singleness. As these principles transcend intentionality, temporality, and multiplicity, they are seen to directly disclose the nature of primordial awareness, in which the meanings of knowing and being are radically transformed. Therefore, the article will also consider the role of these non-dual contemplative principles in deeply changing our understanding of being and knowing alike.

The published document is a part of the working record of The Secretariat of the CPSU Central Committee on May 5, 1969. The employees of The Common Department of the CPSU Central Committee started writing such working records from the end of 1965. In contrast to the protocols, the working notes include speeches of the secretaries of the Central Committee, that allow to deeper analyze the reactions of the top party leadership, to understand their position regarding the political agenda. The peculiarity of the published document is that the Secretariat of the Central Committee did not deal with the most important foreign policy issues. It was the responsibility of the Politburo. However, it was at a meeting of the Secretariat of the Central Committee when Brezhnev raised the question of inviting G. Husák to Moscow. The latter replaced A. Dubček as the first Secretary of the Communist party of Czechoslovakia in April 1969. As follows from the document, Leonid Brezhnev tried to solve this issue at a meeting of the Politburo, but failed. However, even at the Secretariat of the Central Committee the Leonid Brezhnev’s initiative at the invitation of G. Husák was not supported. The published document reveals to us not only new facets in the mechanisms of decision-making in the CPSU Central Committee, the role of the Secretary General in this process, but also reflects the acute discussions within the Soviet government about the future of the world socialist systems.

Interest in wisdom in the cognitive sciences, psychology, and education has been paralleled by conceptual confusions about its nature and assessment. To clarify these issues and promote consensus in the field, wisdom researchers met in Toronto in July of 2019, resolving disputes through discussion. Guided by a survey of scientists who study wisdom-related constructs, we established a common wisdom model, observing that empirical approaches to wisdom converge on the morally-grounded application of metacognition to reasoning and problem-solving. After outlining the function of relevant metacognitive and moral processes, we critically evaluate existing empirical approaches to measurement and offer recommendations for best practices. In the subsequent sections, we use the common wisdom model to selectively review evidence about the role of individual differences for development and manifestation of wisdom, approaches to wisdom development and training, as well as cultural, subcultural, and social-contextual differences. We conclude by discussing wisdom’s conceptual overlap with a host of other constructs and outline unresolved conceptual and methodological challenges.

Renal cell carcinoma (RCC) is one of the common urologic neoplasms, and its incidence has been increasing over the past several decades; however, its pathogenesis is still unknown up to now. Recent studies have found that in addition to tumor cells, other cells in the tumor microenvironment also affect the biological behavior of the tumor. Among them, macrophages exist in a large amount in tumor microenvironment, and they are generally considered to play a key role in promoting tumorigenesis. Therefore, we summarized the recent researches on macrophage in the invasiveness and progression of RCC in latest years, and we also introduced and discussed many studies about macrophage in RCC to promote angiogenesis by changing tumor microenvironment and inhibit immune response in order to activate tumor progression. Moreover, macrophage interactes with various cytokines to promote tumor proliferation, invasion and metastasis, and it also promotes tumor stem cell formation and induces drug resistance in the progression of RCC. The highlight of this review is to make a summary of the roles of macrophage in the invasion and progression of RCC; at the same time to raise some potential and possible targets for future RCC therapy.

Buying Behaviour

Consumer behavior is a complex phenomenon which is evolving according to the time, situations, demographic characteristics of individuals, personality traits, cultural influences etc. The personality of individuals is a unique dynamic organization of the characteristics of a particular person, physical and psychological, which influence behavior and responses to the social and physical environment. It gives the impression that consumer buying is always influenced by their personality. Therefore, many marketers make use of personality traits in the advertisement of products and at the same time they enhance their marketing strategy. The marketers always designed different products and target specific market segments which commonly addressed on individuals personality traits. The individuals few personality traits influence consumer for impulsive buying behavior. The aim of present research is to study the personality traits influence on consumer impulsive buying behavior as it will help to create opportunities of doing business and dealing with customers. The objectives of this research are: (1) to investigate the influence of personality traits on consumer impulsive buying behavior, and (2) to identify the role of gender and their personality traits influence on consumer impulsive buying behavior. To fulfill the purpose of the study, the researchers randomly collected sample and divided them on the basis of gender, 60 males and 60 females. Data were collected from Delhi and NCR region. The data were analyzed using statistical applications such as correlation and t Test. The result was revealed that the common personality traits have a significant relationship with impulsive buying behavior that is psychoticism in the case of male and female. The role of gender has significant differences in impulsive buying behavior. The man showed more impulsive buying behavior compare to women.

The transformation of political science in recent decades opens the door for a new but so far poorly cultivated examination of the common good. Four significant “turns” characterize the modern study of politics and government. Each is rooted in the discipline’s increased emphasis on empirical rigor, with its attendant scientific theory-building, measurement, and hypothesis testing. Together, these new orientations allow political science to enrich our understanding of causality, our basic definitions of the common good, and our view of human nature and society. In particular, the chapter suggests that traditional descriptions of the common good in Catholic theology have been overly irenic and not sufficiently appreciative of the role of contention in daily life, on both a national and international scale.
