BEHAVIOR OF SOILS AND DISSIPATIVE GEOLOGICAL STRUCTURES DURING THE FORMATION OF A LANDSLIDE BLOCK

The peculiarities of soil state and strength and its role as a “weak” layer in the groundmass are often represented as the main factor that determines the occurrence of a landslide or its activation. These concepts are usually extended both to shallow shear landslides and liquefaction-flow types, as well as to deep block landslides, such as compression-extrusion type, with the release of so-called “the main deformable horizon” of soils in the latter. The formation of a new landslide block is accompanied by the occurrence of destructive displacements in the landslide cirque, involving in displacements of the whole slope. Such events are common in urbanized areas, on slopes with the development of deep compression-extrusion landslides. This article discusses the mechanism of formation of a landslide block and the geological features of transformation of the stress-strain state of the ground mass. New data on the behavior of soils at various stages of dissipation are presented, including the case when the dissipative geological structure is separated from the bedrock in the form of a landslide block.</jats:p

Knowledge on postpartum depression among midwives and nurses: a systemic review

Postpartum depression (PPD) is a form of non-psychotic disorder that develops after childbirth with negative consequences for physiological, social and psychological development of the children. The global prevalence of PPD today equals approximately 17.22%. However, almost one half of all cases remain undetected. Healthcare providers can help to reduce the prevalence of PPD by identifying and educating women about the risks and treatment of PPD. The review is the first Russian-language study of systematic selection and qualitative synthesis of the studies in the field of nursing staff knowledge about PPD published from January 2000 to November 2020. The search was conducted in such eligible databases as MEDLINE, PsychINFO, EMBASE, Cinahl, eLIBRARY using the keywords “postpartum depression”, “knowledge”, “detection of postpartum depression”. As a result of the search, it was revealed that knowledge on postpartum depression was superficial in over one half of the midwives and nurses participating in the reviewed studies (n=1777). This result indicates the need to develop and implement training programmes for prevention of postpartum depression among medical personnel. The small amount of unique results underlines the need for further research on the knowledge of postpartum depression among midwives and nurses</jats:p

31. Commission de L’heure

Durant la période de 1933 à 1936 le Bulletin Horaire a donné les heures définitives des signaux horaires d’après la moyenne de 15 observatoires. A partir du Ier janvier 1937 on introduit trois observatoires en plus (Kharkov, Manille et Tokyo), qui communiquent régulièrement leurs résultats au B.I.H.Au Bureau International de l’Heure certains perfectionnements sont actuelle ment en voie de réalisation. Il s’agit d’une horloge à diapason d’une part, et, de l’autre, d’un ensemble nouveau pour l’émission des signaux horaires. M. Lambert va donner une communication sur ce sujet.</jats:p
