extended abstractintroductionin recent years, several studies around the world have shown that land use has a strong impact on water quality, and significant correlations exist between water quality parameters and land use types. generally land use types have adverse impacts on water quality, so positive relationships exist between percentages of these land use types and concentrations of water ...
In the past, transport network design focused on the effect of designs on the transport system alone but not on the land use system, and ignored the land use-transport interaction over time. This may result in obtaining suboptimal designs. Additionally, the impacts of road network improvement policies on the land use system, especially the benefit of landowners cannot be evaluated without consi...
The Hong Kong cadastral system is designed for efficient transactions which has remained unchanged since the enactment of the Land Registration Ordinance in 1844. In this British designed cadastral system, various land-right records are kept by different government departments. The current computerized register gives good protection of ownership rights to practically all land properties. Land u...
The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit ⁄yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contributed to the genetic improvement of wheat, using va...
Brazil is the second country on equine embryo world production. Problems related to the application of equine embryos transfer in Brazil are discussed in this article. The main factor related to low efficacy of Equine Embryos Transfer programs consists in the difficulty to induce multiple ovulations Among the most common difficulties and limitations faced in our country, we emphasize the utiliz...
In 1988, Congress passed the Clinical Laboratory Improvement Amendment (CLIA), thereby extending coverage of the Clinical Laboratory Improvement Act of 1967 to include quality standards for all laboratory-based testing. The CLIA was enacted to ensure the accuracy, reliability, and timeliness of patient test results, regardless of the location where the tests were performed. This article assesse...
Numerous land surface models exist for predicting water and energy fluxes in the terrestrial environment. These land surface models have different conceptualizations (i.e., process or physics based), together with structural differences in representing spatial variability, alternate empirical methods, mathematical formulations and computational approach. These inherent differences in modeling a...
Land use mapping is one of the major applications of remote sensing. While most studies focus on the advanced remote sensing thematic classification algorithms for land use mapping, the scale factor in remote sensing data classification was less recognized. Previous studies showed that while the multi-scale characteristics exist in the remotely sensed data for land use classification, some clas...
Land surface characteristics play a critical role in the evolution of the planetary boundary layer of the atmosphere. Several key components of the land surface that significantly affect surface sensible heat and moisture fluxes include soil temperature and moisture, fractional vegetation coverage (σf ), and green leaf area index (LAI). The lack of observational data for accurate specification ...
This chapter is an introduction to the economics of the connection between urban transportation and land use. The nature of the transportation system strongly influences the patterns of land use in an urban area. Indeed, the long-run histories of urban areas sometimes are identified with the dominant mode of transportation of the time; the age of rail, the age of the automobile, and so on. Supp...
