The selection process for map projections is a mystery to many mapmakers and GIS users. Map projections ought to be selected based on the map’s geographic extent and the required distortion properties, with the goal of minimizing the distortion of the mapped area. Despite some available selection guidelines, the selection...
Recent advances in wireless technologies have helped the proliferation of wireless devices, ranging from hand-held devices such as cellular phones to more powerful mobile computing platforms as such laptops [1]. Along with that, the end users’
applications running on these devices, ranging from text message to multimedia applications such as...
Calcium (Ca) is an essential macronutrient that is increasingly recognized as a biogeochemical factor that influences ecosystem structure and function. Progress in understanding the sustainability of ecosystem Ca supply has been hampered by a lack of information on the various forms and pools of Ca in forest ecosystems. In particular,...
This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...
The fundamental aim of this study was to determine how Malaysians define both leisure
and recreation. Two ethnic groups, Chinese and Malays, and rural and urban variants of these
groups were included in the sample. The other objective was to determine if there were differences
in the definitions due to...
The environmental movement needs people from communities of color and the differing perspectives they provide. Latinas/os are one of the largest communities of color in the US, and their numbers continue to grow. However, mainstream environmental organizations have failed to engage this community in authentic ways. The lack of meaningful...
Community science (also called citizen science) has become an increasingly popular data collection technique for scientists researching nature at a large scale. Many ecologists have also looked to community science as a method for educating the public about science. Over the past several decades, researchers have attempted to define an...
Replication of plasmid molecules containing either a left-end or a
right-end adenovirus origin was investigated. When the plasmids were
linearized to expose their respective adenovirus termini, mixed, and
transfected with helper adenovirus DNA into the human 293 cell line, a
new molecule was detected. The new molecule was the size...
Conversion of exogenous cis-zeatin to trans-zeatin in immature seeds of
Phaseolus vulgaris L. led to the isolation of a cis-trans isomerase from the endosperm.
The enzyme was purified over 2000-fold by chromatography on a series of FPLC
(anion exchange, gel filtration, and hydrophobic interaction) and Concanavalin A
columns. Non-enzymatic isomerization...
