Based on the complex studies (geographical-geological, karst-speleological, and geophysical studies), conducted by the authors in the study area, karst forms such as sinkholes and ponors were identified, the width (2-17 m) of the Quaternary deposits located on the limestones were determined, the average and maximum discharges of the streams flowing on the bottom of the hollow were calculated. Studies have also shown that relatively heavy rains and snowmelt periodically flood the relatively low, western part of the hollow and create a temporary lake that soon dries up through the ponors at the bottom of the hollow, where the water stream are discharged. The closed shape of the Turchu hollow the limestone bottom covered with Quaternary deposits and the events described above indicate the corrosive origin of the hollow, which has been practically confirmed by our georadiological and electrometric studies. It is notable that the role of tectonic movements in the origin of the hollow along with the corrosive processes, which had a periodic character, and together with the uplifting of the area caused the lowering of the levels of underground waters and, consequently, the activation of karst processes.

AbstractThe historical discovery and the successive stages in our knowledge of the family Stenasellidae Dudich, 1924, are described. Their morphological features; the diagnosis of the family, and an updated list of its genera with the respective numbers of their taxa and their main characteristics are given. Also, the biogeography and the ecology of the group and relations between burrowing behaviour and general adaptation to life in all types of continental underground waters, are discussed. Next, the putative evolutionary history of the family is presented, taking into account the active dispersal of these isopods and also the role of Quaternary events: the development of aridity in the northern tropical zone and the occurrence of glaciations in the temperate zones of the Northern Hemisphere. Their general biological adaptation to the absence of circadian stimuli is examined vis-a-vis the fact that biological rhythms are synchronized with the annual flooding events in the subterranean environment. Decouverte historique et progres successifs de la connaissance de la famille des Stenasellidae Dudich, 1924. Caracteres morphologiques originaux; diagnose de la famille; liste mise a jour des genres, nombre de leurs taxons et principales caracteristiques. Biogeographie et ecologie du groupe; relations entre le comportement fouisseur et l'adaptation a la vie dans tous les types de milieux des eaux souterraines continentales. Histoire evolutive presumee de la famille, tenant compte de la capacite d'expansion active de ces Isopodes et du role des evenements quaternaires: developpement du climat aride dans la zone nord-tropicale et intervention des glaciations dans les zones temperees de l'hemisphere nord. Adaptation generale des processus biologiques a l'absence de stimuli externes circadiens, ces processus etant rythmes par la pulsation annuelle du flux des eaux dans l'environnement souterrain, qui joue le role d'un stimulus circannien.

The wide circulation of Klebsiella bacteria in water of water objects of different climatic zones of Russia and various function is established. So bacteria of the Klebsiella strain are in superficial sources of the centralized water supply depending on extent of their biological and chemical pollution; underground waters at the unprotected water-bearing horizons; in drinking water at insufficiently effective system of its cleaning and disinfecting. Klebsiella circulating in water was shown to keep properties of pathogenicity and a virulence, possess resistance both to modern preparations and disinfecting agents (chlorine, an ultraviolet to radiation). Bacteria of the Klebsiella strain have high penetration in the water-bearing horizons. At strains of Klebsiella there is allocated considerable pathogenic potential (adhesive, invasive, phosphatase, lecithinase, DNA-ase, hemolytic activity) and genetic markers of pathogenicity of cnf-1. The etiologic role of bacteria of Klebsiella and an infecting (100, COE/dm3) dose emergence of acute intestinal infections (AII) is established. Detection of Klebsiella in water objects and especially in water of drinking appointment, in the absence of total coliform bacteria (TCB) contributes to the epidemic danger of water use.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
