Forty-six morphological characters were used in a study of Triticum turgidum ssp. carthlicum (2n = 28) and specimens of carthlicum-like forms of Triticum aestivum ssp. vulgare (2n = 42). The morphological variation patterns within these groups were examined using stepwise discriminant analysis. These results indicate that specimens studied could be...
John Wesley Powell worked actively for public land system
reform while a director of geographical and geological surveys in
the West from 1869 to 1894. Although this has won him acclaim as a
conservationist, the basis of Powell's linkage of reform with
scientific work is poorly understood.
A study of...
Triticale, a newly man-made cereal from a wheat-rye cross offers a
unique food and feed potential because of its higher protein content
with nutritionally balanced amino acid composition as compared to other
cereal grains. However, some cereal proteins such as trypsin inhibitors,
present in triticale and rye, can affect the...
The Sulaiman foldbelt is an active and conspicuous tectonic
feature on the northwestern margin of the Indo-Pakistani plate.
Seismic reflection data have been combined with surface geological
mapping and drillhole data to interpret the structural style and
tectonic shortening of the eastern Sulaiman foldbelt and its adjacent
foredeep. The data...
The Salt Range and Potwar Plateau are part of the currently active
foreland fold-thrust belt of the Himalaya in Pakistan. Seismic reflection data have been combined with surface mapping, drillhole and
paleomagnetic information to construct balanced structural cross-sections of the current frontal thrust zone (Salt Range), and to estimate
the...
From the earliest English colonization to the present day, there
has been interest in astronomy in this country. The purpose of this
thesis is to show how the science of astronomy developed in America
from the earliest observations by educated colonists using imported
instruments and publishing in European journals, to...
A study of populations characteristics of T. turgidum ssp.
carthlicum and T. aestivum ssp. carthlicoides was completed using
numerical analysis. A sample of 74 accessions of ssp. carthlicum
and 20 of ssp. carthlicoides were scored for 46 characters. It was
established that three morphological distinguishable groups of ssp.
carthlicum can...
Rare plant reintroductions that result in additional or more viable wild populations are important conservation tools for maintaining biodiverse ecosystems. Ideally, such projects are best designed as experiments, to improve biological and ecological knowledge of the selected species and monitoring long-term results. Northern wormwood (Artemisia campestris var. wormskioldii: Asteraceae), a...
The North Potwar Deformed Zone (NPDZ) is part of the active foreland fold-and-
thrust belt of the Salt Range and Potwar Plateau (SR/PP) in northern Pakistan.
About 500 km of seismic reflection profiles are integrated with surface geologic and
drilling data to examine the structure of the NPDZ, in general,...
The resurgence of creationism the past few years has been led by advocates
of recent-creationism. These individuals, a minority among creationists in general,
argue that the entire universe was created approximately 10,000 years ago in one six-day
period of time. Recent-creationists support their position by appealing to the
Genesis account...
