INTSORMIL Presentations
INTSORMIL was created in 1979 by USAID and BIFAD as a long-term mechanism for agriculture development. It is meant to utilize capacity of U.S. land grant universities increase research capacity Increase food production. INTSORMIL was replaced in 2006 by the SMOG, Sorghum, Millet and Other Grains CRSP. The focus of these programs in Africa has been on sorghum, pearl millet, finger millet, tef, and fonio. The programs have facilitated investigation of soil and water (environmental considerations), integrated pest management, nutrition and health, broadening market access, mitigating post-harvest constraints, enhancing productivity and livelihood in marginal areas, increasing income, improving food quality, …
Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi
Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi
Fathi Habashi
The mechanism of leaching of semiconducting minerals such as PbS, ZnS, UO2, etc., has been the subject of intensive speculation by hydrometallurgists in the early 1950s. The electrochemical mechanism proposed in 1970 by the author in volume 2 of his Principles of Extractive Metallurgy avoids the assumption of forming intermediate complexes that cannot be isolated or identified.

Sorghum Breeding Programme, Medson Chisi
INTSORMIL Presentations
Overall the project has been a success--the challenge is to supply sufficient seed.
A sustainable seed distribution system is needed for farmers living in remote areas.
The Sorghum Programme requires continued support from all stake holders--collaboration.
There is need to link farmers to potential markets.
Most farmers have expressed the need for assistance in terms extension service and inputs.
Sorghum is an important crop as it is a direct substitute for maize.
Stock feed companies have also expressed willingness to purchase sorghum if more farmers are able to grow sufficient quantities.
Growth And Species Interactions Of Eucalyptus Pellita In A Mixed And Monoculture Plantation In The Humid Tropics Of North Queensland, Mila Bristow, Jerome K. Vanclay, Lyndon O. Brooks, Mark Hunt
Growth And Species Interactions Of Eucalyptus Pellita In A Mixed And Monoculture Plantation In The Humid Tropics Of North Queensland, Mila Bristow, Jerome K. Vanclay, Lyndon O. Brooks, Mark Hunt
Dr Lyndon O Brooks
This study investigated whether mixed-species designs can increase the growth of a tropical eucalypt when compared to monocultures. Monocultures of Eucalyptus pellita (E) and Acacia peregrina (A) and mixtures in various proportions (75E:25A, 50E:50A, 25E:75A) were planted in a replacement series design on the Atherton Tablelands of north Queensland, Australia. High mortality in the establishment phase due to repeated damage by tropical cyclones altered the trial design. Effects of experimental designs on tree growth were estimated using a linear mixed effects model with restricted maximum likelihood analysis (REML). Volume growth of individual eucalypt trees were positively affected by the presence …

Sorghum And Pearl Millet Improved Seed Value Chains In Zambia: Challenges And Opportunities For Smallholder Farmers, Priscilla Hamukwala, Gelson Tembo, Don Larson, Mark Erbaugh
Sorghum And Pearl Millet Improved Seed Value Chains In Zambia: Challenges And Opportunities For Smallholder Farmers, Priscilla Hamukwala, Gelson Tembo, Don Larson, Mark Erbaugh
INTSORMIL Scientific Publications
Sorghum and millet are a very important source of food and farm income for smallholder farmers, which can be enhanced especially if linked to new markets. These two crops have been widely viewed as minor traditional crops in the Zambian food systems. The two crops were displaced by maize in the 1900s with the opening of the copper mines. However, they remain important food crops for semi-arid areas of the country. In recent years, there have also been new market developments requiring farmers to increase productivity and production. Unfortunately significant productivity enhancements are impeded by low access to improved technologies …
Guano Exploitation In Madagascar, Christina Buliga
Guano Exploitation In Madagascar, Christina Buliga
Independent Study Project (ISP) Collection
Agriculture in Madagascar continues to remain largely undeveloped. Out of the eighty percent of Malagasy individuals that live in rural areas an overwhelming sixty five percent practice subsistence agriculture. With respect to the country as a whole this means that out of Madagascar's 58.2 million hectares of available land only 5.2 percent (3 million hectares) are farmed. And out of these 3 million hectares only 67% are cultivated permanently and only 11% are fertilized.
While there are several reasons for why Madagascar’s agriculture has remained largely undeveloped and for why Madagascar continues to rely on imported crops to meet its …

A Comparison Of Costs And Returns For Organic And Conventional Cabernet Sauvignon Grape Production In San Luis Obispo County, Amanda N. Johansen
A Comparison Of Costs And Returns For Organic And Conventional Cabernet Sauvignon Grape Production In San Luis Obispo County, Amanda N. Johansen
Agribusiness
This study examined the differences in costs and profitability for established conventional and organic Cabernet Sauvignon vineyards in the Edna Valley region of San Luis Obispo County, California. The study used a partial budgeting approach to compare cost and profitability for established vineyards for 2009, and thus ignored transition costs. Data were obtained from UC Davis cost studies for organic and conventional grape production in other regions of California in previous years. Adjustments made to these costs to account for changes in input use, input costs and grape prices in San Luis Obispo County during the 2009 growing season.

Evaluating Native Wheatgrasses For Restoration Of Sagebrush Steppes, Jayanti Ray Mukherjee
Evaluating Native Wheatgrasses For Restoration Of Sagebrush Steppes, Jayanti Ray Mukherjee
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Pseudoroegneria spicata and Elymus wawawaiensis are two native perennial bunchgrasses of North America's Intermountain West. Frequent drought, past overgrazing practices, subsequent weed invasions, and increased wildfire frequency have combined to severely degrade natural landscapes in the region, leading to a decline in the abundance of native vegetation. Being formerly widespread throughout the region, P. spicata is a favorite for restoration purposes in the Intermountain West. Elymus wawawaiensis, which occupies a more restricted distribution in the Intermountain West, is often used as a restoration surrogate for P. spicata. However, since most restoration sites are outside the native range of …

Professor Emmanuel Ohene Afoakwa
Studied were conducted to evaluate the combined effects of spontaneous fermentation and Amylase Rich Flours (ARF) on some nutritive value, functional and viscoelastic properties of cowpea-fortified nixtamalized maize. A 2x3x3 factorial design, with fermentation medium, fermentation time and ARF level was performed. The blends were fermented for the specific times and analysed for their titratable acidity, pH, water absorption capacity, viscoelastic properties, texture, protein and mineral content. Fermentation and ARF addition influenced titratable acidity, pH, water absorption, viscoelastic properties and texture of the cowpea-fortified nixtamalized maize. Addition of ARF decreased the viscoelastic properties, texture and pH of all the blends …

Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi
Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi
Fathi Habashi
While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can be solved if two new terms are adopted: typical and less typical metals. These new terms will also help reconcile the European Periodic Table versus the North American regarding numbering of groups as well as the IUPAC numbering which could be as well abandoned in favour of group names as will be shown in the manuscript.

Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi
Aqua Science Through The Ages. An Illustrated History Of Water, Fathi Habashi
Fathi Habashi
Water a component of the Four Elements considered by the ancient philosophers as essential for survival, played, and is still playing an essential role in society. Great civilizations in ancient times developed along great rivers. The ancient peoples knew how to manage water supplies by digging canals, controlling floods, and using water for irrigation. They designed equipment that used water to measure the time, to determine the density of solids, to fight fires, and to create vacuum. Modern engineers exploited water flow to design and construct huge hydroelectric power stations. Waterways and navigation systems were also an essential element for …

Viscoelastic Properties And Pasting Characteristics Of Fermented Maize: Influence Of The Addition Of Malted Cereals, Dr. Emmanuel Ohene Afoakwa (Phd), Randy Adjonu, Justice Asomaning
Professor Emmanuel Ohene Afoakwa
Investigations were conducted on the viscoelastic properties and pasting characteristics of fermented maize with malted cereals and their suitability for infant feeding. A 3x3x2 factorial experimental design with malting time, cereal malt concentration and cereal type was used. Maize, millet, and sorghum malts were added to fermented maize to reducing its bulk density. Samples were analysed for their viscoelastic properties and pasting characteristics using Brabender Viscoamylograph. Sorghum malt in comparison to millet and maize malts was not effective in terms of lowering the hot and cold paste viscosities of the fermented maize. Maize and millet malts liquefied the dough considerably …

Acidification And Starch Behaviour During Co-Fermentation Of Cassava And Soybean Into Gari., Dr. Emmanuel Ohene Afoakwa (Phd), Edem John Kongor, George Annor, Randy Adjonu
Professor Emmanuel Ohene Afoakwa
Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods. Starch breakdown and pasting characteristics were also analysed using Brabender Viscoamylograph. Fermentation caused significant variations in the pH, non-volatile acidity and starch concentration. The pH decreased with concomitant increases in non-volatile acidity during co-fermentation of the cassava dough. Soy-fortification upto 20% caused only minimal effects on the pH, titratable acidity and starch content during the fermentation period. Starch content decreased from 69.8%-60.4% within the 48 h fermentation time …

Professor Emmanuel Ohene Afoakwa
Response surface methodology was used to optimize the processing conditions in the preparation of cowpea tempeh. The independent factors studied were boiling time (varying from 5 to 30 min), incubation time (varying from 12 to 48 h) and incubation temperatures (varying from 25 to 50°C), whereas the dependent factors were protein content, protein solubility, pH, titratable acidity and total color difference (using L, a* and b*). Regression models were generated and adequacy was tested with regression coefficients (R2) and the lack-of-fit tests. Optimum processing conditions were determined by method of superimposition. There was a strong and significant influence (P < 0.01) of the quadratic effect of the incubation time on the protein content of the cowpea tempeh, with similar significance (P < 0.01) noted in protein solubility with increasing boiling time. The optimum processing conditions observed for the preparation of cowpea tempeh were boiling time of about 20 min, incubation time of about 28 h and incubation temperature of about 37°C.
