Self‐help and Volunteerism in Tanzania in the 1960s: Voluntary Labour, Nation Building and Constructing Modernity

Development and Change, EarlyView.
ABSTRACT The United Nations has declared 2026 the International Year of Volunteers for Sustainable Development. Against that backdrop, this article examines the experience of volunteerism, and specifically self‐help voluntary labour in Tanzania in the early colonial period, to explore the place of volunteerism in the construction of the post‐colonial ...

Numerical Simulation and Analysis of Swirling Flow in the Draft Tube Cone of a Francis Turbine [PDF]

The paper presents numerical investigations of decelerated swirling flows specific to hydraulic turbines draft tube cone, within the framework of axisymmetric flow models. First, we investigate the behaviour of a Burgers vortex in a diffuser as the swirl

Time-accurate Numerical Simulations of Swirling Flow with Rotor-stator Interaction

, 2015
A series of numerical simulations is undertaken to study a highly swirling turbulent flow generated by rotor-stator interaction in a swirl generator. The purpose is to assess the applicability of different turbulence models in swirling flow with a high ...

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming

Gender, Work &Organization, EarlyView.
ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...

4‐1BB Expression and Signaling Regulates MAIT Cell Activation and Effector Functions

Immunology &Cell Biology, EarlyView.
4‐1BB is a highly expressed TNFRSF co‐stimulatory receptor on MAIT cells upon activation. Expression and signaling via 4‐1BB enhance activation and provide co‐stimulation, boosting MAIT cell effector responses to TCR‐mediated activation. ABSTRACT Mucosal associated invariant T (MAIT) cells are abundant unconventional T cells that recognize microbe ...

The importance of the knowledge of flow stream in water sump pump [PDF]

, 2013
Numerous different experimental and numerical methods have been developed and are already improved in order to get rather good flow descriptions inside pump components. These calculations are generally realized assuming uniform and steady flow conditions,
