Charging Technology for Battery Electric Buses
The charging infrastructure has a key role in the implementation of battery electric buses (BEBs) in cities. BEBs only use off-board chargers, whereas the PEC to convert the three-phase AC power from the grid into DC power to charge the battery is located outside the BEB. These chargers allow higher charging power levels because they are not restricted in size and weight. Furthermore, since the driving range of a BEB is limited, a specific charging concept and interface is required to keep the BEB running during the day. This entry gives an overview of the existing charging interfaces and concepts and charger and PEC topologies to provide a reliable and efficient charging behavior.

Iron-Containing Oral Contraceptives
Oral contraceptive use has been associated with decreased menstrual blood losses; thus, can independently reduce the risk of anemia and iron deficiency in women. Manufacturers have recently started to include supplemental iron in the non-hormonal placebo tablets of some contraceptives.

Liberal Socialism
Liberal socialism is a socialist political philosophy that incorporates liberal principles. Liberal socialism does not have the goal of completely abolishing capitalism and replacing it with socialism, but it instead supports a mixed economy that includes both private property and social ownership in capital goods. Although liberal socialism unequivocally favors a mixed market economy, it identifies legalistic and artificial monopolies to be the fault of capitalism and opposes an entirely unregulated economy. It considers both liberty and equality to be compatible and mutually dependent on each other. Principles that can be described as liberal socialist are based on the works of philosophers such as John Stuart Mill, Eduard Bernstein, John Dewey, Carlo Rosselli, Norberto Bobbio, Chantal Mouffe and Karl Polanyi. Other important liberal socialist figures include Guido Calogero, Piero Gobetti, Leonard Hobhouse, John Maynard Keynes and R. H. Tawney. To Polanyi, liberal socialism's goal was overcoming exploitative aspects of capitalism by expropriation of landlords and opening to all the opportunity to own land. Liberal socialism has been particularly prominent in British and Italian politics. Liberal socialism’s seminal ideas can be traced to John Stuart Mill, who theorised that capitalist societies should experience a gradual process of socialisation through worker-controlled enterprises, coexisting with private enterprises. Mill rejected centralised models of socialism that could discourage competition and creativity, but he argued that representation is essential in a free government and democracy could not subsist if economic opportunities were not well distributed, therefore conceiving democracy not just as form of representative government, but as an entire social organisation.

Rural Planning
Rural planning is a broad academic term and human practice covering a range of topics, such as rural landscape, industry development, livelihoods of villagers and farmers, environmental conservation, and health care delivery. The objective of rural planning is to achieve rural development through the allocation and management of resources, mediated by developmentalist configuration and local communities. Rural planning could be organized at different levels, from global, national, and regional plans to plans at a village level. The time span of a rural planning is also very diverse, ranging from years to decades.

Olfaction and Ligand–Receptor Interaction
Odorant or olfactory receptors (ORs) are located in the human nose, in the olfactory epithelium. The olfactory receptors can recognize many different odor molecules of a diverse protein sequence, and OR genes constitute the most abundant family of G protein-coupled receptors (GPCRs). The human receptor gene family comprises 339 receptor genes and 297 receptor pseudogenes, unequally dispersed in 51 distinct loci on 21 human chromosomes. Humans have a compassionate sense of smell, which is essential for discovering odors necessary for maintaining a healthy life, such as the smell of smoke (detection of fire) and rotten food (to avoid ingestion).

Carbonaceous Biochemical Oxygen Demand
Carbonaceous biochemical oxygen demand or CBOD is a method defined test measured by the depletion of dissolved oxygen by biological organisms in a body of water in which the contribution from nitrogenous bacteria has been suppressed. CBOD is a method defined parameter is widely used as an indication of the pollutant removal from wastewater. It is listed as a conventional pollutant in the U.S. Clean Water Act.
