Sustainable designEnvironmentally sustainable design (also called environmentally conscious design, eco-design, etc.) is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfort of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance.
Modular groupIn mathematics, the modular group is the projective special linear group of 2 × 2 matrices with integer coefficients and determinant 1. The matrices A and −A are identified. The modular group acts on the upper-half of the complex plane by fractional linear transformations, and the name "modular group" comes from the relation to moduli spaces and not from modular arithmetic. The modular group Γ is the group of linear fractional transformations of the upper half of the complex plane, which have the form where a, b, c, d are integers, and ad − bc = 1.
Bicycle-friendlyBicycle-friendly policies and practices help some people feel more comfortable about traveling by bicycle with other traffic. The level of bicycle-friendliness of an environment can be influenced by many factors including town planning and cycling infrastructure decisions. A stigma towards people who ride bicycles and fear of cycling is a social construct that needs to be fully understood when promoting a bicycle friendly culture.
Private sector developmentPrivate sector development (PSD) is a term in the international development industry to refer to a range of strategies for promoting economic growth and reducing poverty in developing countries by building private enterprises. This could be through working with firms directly, with membership organisations to represent them, or through a range of areas of policy and regulation to promote functioning, competitive markets. Supporters argue that PSD is an important part of poverty reduction.
