Uses Of Wild Plants In Ndumba, Eastern Highlands Province, Terence Hays

Terence Hays

For Papua New Guineans,l as well as for those who wish to understand them better, traiditional knowledge of the local natural environment is a priceless resource. In the face of increasing commitments to a cash economy, however, many communities are rapidly losing their awareness and appreciation of the rich animal and plant worlds which are immediately available to them. As Powell has recently observed (1976), the recorded information regarding traditional plant knowledge and uses has tended to be widely-scattered in the literature and relatively difficult to access, especially for those who stand to benefit the most from it. A recent …

Purification And Characterization Of Novel Nucleases From A Thermophilic Fungus, Kyle Landry

Kyle S Landry

A thermophilic fungus was isolated from composted horse manure. The organism was as a Chaetomium sp. by sequencing the highly conserved ITS region of the fungus and comparing to known regions in a genomic database and was referred to as TM-417. TM-417 was found to have an optimal growth temperature of 45 ^oC and an optimal pH of 7.0. An extracellular DNase and RNase was found to be produced by the isolate and were purified 145.58-fold and 127.6-fold respectively using a combination of size exclusion chromatography and a novel affinity membrane purification system. The extent of purification was determined …

G00-1778 Field Windbreaks, James Brandle, Laurie Hodges

Laurie Hodges

gricultural producers face many challenges as they try to balance efficient production systems with increasing environmental demands. For these systems to be successful, they must optimize the balance between inputs and final production. Field windbreaks are one way to increase yields while at the same time reducing inputs and improving both environmental quality and production efficiency. Windbreaks reduce wind speed and alter the microclimate in sheltered areas. Field windbreaks reduce wind erosion and the damage to crops caused by wind-blown soil. They improve water use efficiency, reduce risks associated with drought, and manage blowing snow.

Field windbreaks provide positive economic …

An Assessment Of Behavioural Syndromes In Rangeland-Raised Beef Cattle, Robert Wesley, Andrés Cibils, J. Mulliniks, Emily Pollak, Mark Petersen, Ed Frederickson

Ed L. Frederickson

Individuals in most animal groups exhibit consistent behavioural differences across situations or over time known as behavioural syndromes. We conducted a study with a herd of young rangeland-raised cows to determine whether animals exhibited consistent differences in foraging behaviours across contexts (confinement vs. rangeland pasture) and could be clustered into behavioural type groups on the basis of a suite of correlated behaviours. We also investigated whether cows with different behavioural types performed differently in this environment. Supplement consumption rate (SCR) in confinement was used to select two groups of cows (fast eaters vs. slow eaters). This classification was validated by …

Characterising The Spatial And Temporal Activities Of Free-Ranging Cows From Gps Data, Dean Anderson, Craig Winters, Rick Estell, Ed Frederickson, Marek Doniec, Carrick Detweller, Daniela Rus, Darren James, Barbara Nolen

Ed L. Frederickson

Electronic tracking provides a unique way to document behaviour by cows on a continuous basis. Over 2 years 17 beef cows with calves were fitted with global positioning system (GPS) devices programmed to record uncorrected GPS locations at 1-s intervals in a semi-desert rangeland. Each cow was periodically observed during daylight hours and foraging, walking and stationary (standing/lying) activity times were recorded across days and individual cows to calculate a mean travel rate for each activity. Data without observers present were collected immediately preceding and following the abrupt weaning of calves at between 223 and 234 days of age to …

Food, Fibre And The Future : Report On Surveys Of Students’ And Teachers’ Knowledge And Understanding Of Primary Industries, Kylie Hillman, Sarah Buckley

Kylie Hillman

Primary Industry plays a vital role in Australian’s economy and society, but the gap between rural and urban communities is growing, contributing to a lack of understanding of where food and other basic necessities of life come from. The goal of the Primary Industries Education Foundation (PIEF) is to provide a source of information on primary industries for educators, to better equip students with not only knowledge about what goes into their food and fibres but also what career opportunities exist in primary industries. In 2010, PIEF contracted the Australian Council for Educational Research (ACER) to design and conduct a …

Viability Of Lactic Acid Bacteria And Sensory Evaluation In Cinnamomum Verum And Allium Sativum-Bio-Yogurts Made From Camel And Cow Milk, Ahmad Salihin Hj Baba, Shori A. B.

Ahmad Salihin Hj Baba

The present study investigate the effect of herbal water extract prepared from Allium sativum and Cinnamomum verum on the viability of lactic acid bacteria (Lactobacillus spp and Streptococcus thermophilus) in cow- and camel-milk yogurts during 21 day refrigerated storage. The organoleptic properties of fresh-yogurts were evaluated. Lactobacillus spp count for fresh cow milk-yogurts (0 day) in both present and absent of C. verum and A. sativum was ranged from 1.4×0 6 to 2.1×10 6 cfu/mL. These values were not significantly changed throughout the 21 days of refrigerated storage. Lactobacillusspp count in fresh plain camel milk- yogurt was 13.2×10 6 cfu/mL …
