Mixed Super‐Circles

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

Exploring children's experiences of schooling in Tanzania: How the ‘hidden curriculum’ undermines aspirations for sustainable development

open access: yesChildren &Society, EarlyView.
Abstract In the context of aspirations that firmly position education as the key to multiple global development goals, we raise concerns about how education is experienced by many children, particularly in low‐income, postcolonial contexts. Drawing from two, in‐depth qualitative studies in Tanzania, we demonstrate that existing pedagogical practices ...

Collembolan communities (Hexapoda: Collembola) from the Buzău Land Geopark (Buzău Mountains, Romania)

open access: yesTravaux de l'Institut de Speologie Emile Racovitza, 2018
The authors present the Collembola species collected from the Buzău Land Geopark (Buzău Mountains, Romania). The uniqueness of the Buzău Land Geopark is illustrated by the presence of very rare collembolan species such as Friesea afurcata (Denis, 1926 ...

Helicopter drops in an open economy when markets are incomplete

open access: yesEconomic Inquiry, EarlyView.
Abstract We characterize the spillover effects of helicopter drops and optimal monetary policy in a tractable two‐country overlapping generations model with incomplete markets. As helicopter drops can affect the distribution of income across countries, they create room for redistribution policies which are particularly relevant when agents are ...

Geological and hydrogeological research, tools for karst management in the north of the Caraş Gorges (Banat Mountains, Romania)

open access: yesTravaux de l'Institut de Speologie Emile Racovitza, 2010
The karst geosystems functioning frequently implies very quick mass and energy transfers, which make them highly sensitive to any natural or anthropogenic disturbance.

Potential of organogel‐based colloidal hydrogels for new cosmetic formulations

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Colloidal hydrogels are formed by combining anionic, cationic, or nonionic surfactants with two oils of cosmetic interest: sweet almond oil and phytosqualane. These systems are obtained through hot emulsification followed by cooling, which leads to the aggregation of gel‐like particles.
