The reader will find guidelines for the implementation of virtual communities including considerations for design, management issues, and requirements for resources.
Among these, specialised woodpeckers (Aves: Picidae) have been affected negatively due to their high requirements for resources that are scarce in managed forests.
Furthermore, low grass growth and high female resource demand, during early spring, mean that requirements for resources may exceed their availability (Clutton-Brock & Pemberton 2004).
The challenges in designing products and production systems are becoming increasingly complex due to more changeable customer demands, frequent product updates, and the requirements for resource efficiency.
For example, requirements for resource use in patients with HCAP were different to those in patients with CAP.
We assumed a minimum set of requirements for resource-constrained, district-level health services in Kenya: access to a computer, limited knowledge of a spreadsheet application, and availability of at least 5 years of admission records from a health facility.
Obtaining the spatiotemporal variations of precipitation and runoff is the principal requirement for water resources planning in rather large catchments.
Many in vitro BBB models have proven useful for predicting the BBB permeation rate, but do not meet all criteria for use in early-stage drug discovery: feasibility, rapidity, reliability and a low requirement for human resources.
Conventional breeding has limitations of narrow genetic base, a highly heterozygous nature because it is cross-pollinated, a perennial nature, and a requirement for heavy resources (land and other inputs).
