    Finite element equations are developed for studying deformations and temperatures resulting from frictional heating in sliding system. The formulation is done for linear steady state motion in two dimensions. The equations include the effect of the velocity on the moving components. This gives spurious oscillations in their solutions by Galerkin finite element methods. A method called streamline upwind scheme is used to try to deal with this deficiency. The finite element program is then used to investigate the friction of heating in gas path seal

    Air dried whole coffee fruits, beans and husks from China, India and Mexico were analysed for their chlorogenic acids (CGA), caffeine, and polyphenolic content. Analysis was by HPLC and Orbitrap exact mass spectrometry. Total phenol, total flavonol and antioxidant capacity were measured. The hydroxycinnamate profile consisted of caffeoylquinic acids, feruloyquinic acids, dicaffeoylquinic acids and caffeoyl-feruloylquinic acids. A range of flavan-3-ols as well as flavonol conjugates were detected. The CGA content was similar for both Mexico and India coffee fruits but was much lower in China samples. Highest levels of flavan-3-ols were found in the Indian samples whereas Mexico samples contained the highest flavonols. Amounts of CGAs in the beans were similar to those in the whole fruits, but flavan-3-ols and flavonols were not detected. The husks contained the same range of polyphenols as in the whole fruits. Highest levels of caffeine were found in the Robusta samples

    Citation: Mullen, Roger B. The Galloway cattle. Senior thesis, Kansas State Agricultural College, 1902.Morse Department of Special CollectionsIntroduction: The Galloway cattle are a hardy hornless breed of beef cattle which take their names from the province of Galloway, which now comprises the stewarty of Kirk and Bright and the shire of Wigton but formerly included the shires of Ayrshire, Lanark, Reuben and Dumfries. The province now includes a strip of land about ninety miles long. It is a county which has high up lands richly covered with good pastures, and the valleys are very fertile, while the hills are densely covered with woods. Numerous small lakes and rivers are found along which are found rich moor lands. The climate while mild is damp and at times cold. 1st Theory of - Youdtt in his work on the cattle of G.B. says “There appears to be the remnants of two distinct breeds of native or aboriginal cattle. The first are middle horned while the second are polled. The Galloways, Augers, Suffolk and Norfolk breeds came from these polled cattle, while the Devon, Hereford, Sussex, and Highland breeds came from the horned cattle. 2nd Theory – The most plausible theory as to the origin of the Galloway Breed is that they were brought into Scotland, from Scythia through Europe and Ireland by the Scots who originally lived in Scythia. Herodotus, the historian, who wrote about B.C. 400 says, “In Scythia the oxen have no horns” and it is probable that the Galloways there came from the old Scythian breed of polled cattle. The believers of this latter theory account for the appearance of wild polled cattle in England by saying that in the comparative roving and uncertain life of the earlier settlers of Scotland led, their cattle would sometimes get lost in the forests, and as there was plenty of feed they thrived and thus started the wild breed. The difference in environment causing the different breeds to spring up

    LONG-RUN STRIGA CONTROL BY SUBSISTENCE FARMERS IN MALI

    Get PDF
    A dynamic programming model is developed to identify barriers to the adoption of long-run control programs for the parasitic weed Striga. The model is applied to Sirakorola in northwestern Mali. The ability of national and village-level institutions to overcome the barriers to adoption is explored.Community/Rural/Urban Development, Research and Development/Tech Change/Emerging Technologies,
