As the world population increases and resources become more coveted, water emerges as a key component to global food security. The Middle East and North Africa (MENA) is among the driest regions in the world: containing just one percent of the world's freshwater resources. An in…
An integrated process was developed to hydrolyze the phytates in light steep water (LSW) and to simultaneously isolate inorganic phosphate (Pi) and myo-inositol products. The proposed integrated process is helpful in resolving the environmental and nutritional concerns in the us…
The utilization of tropical fruit biomass as feedstock for biorenewable resources is an attractive proposition due to its abundance and potential to reduce reliance on conventional sources as well as the overall economic gain to all stakeholders. This study aims to pave the way …
Two slotted two-dimensional spouted bed units with flexible bed dimensions were designed and fabricated. Static vertical pressure of grains (shelled corn, soybean, and wheat) on the air entry slots in the pilot scale unit indicated that the silo theories are not applicable to pr…
A follow-up study was conducted on Ag. 450 graduates of 1969 through 1989 to evaluate the course. Ag. 450, a 3-credit course, has been offered at Iowa State University for about 50 years. It provides hands-on experience for students in applied farm management. The goal of this s…
A perennial problem of the Malaysian rice industry is the inadequate drying capacity of the dryers for properly handling bumper harvests and very wet grain at the private and public rice mills. The concurrentflow (CCF) dryer and the in-bin counterflow (IBCF) dryer, both used at …
L'objectif de cette etude etait de modeliser la teneur en eau et le rendement de la pomme de terre a Quebec. Pour cela, la performance des modeles SUBSTOR et SWACROP a ete evaluee pour la teneur en eau et le rendement durant deux saisons de croissance (1992 et 1993). En utilisan…
A number of alternatives were considered to keep pecan processing economically competitive and sustainable. The industry needed a low risk evaluation technique for testing new high capital plant configurations. A simulation model was developed using the AweSimTM simulation syste…
Sea water samples were collected from different sampling stations along the Lebanese coast in the summer of 1994. Chemical, biological and physical analysis were conducted to assess the recreational water quality in Lebanon. Some 125 samples were then analyzed for the presence o…
Egypt has very limited surface water resources, perhaps surprisingly the country has quite plentiful water available from shallow wells. If water could be lifted from these wells, much more of the country could be used for growing crops. Lack of capital investment and expense of…
Alfalfa cubes are transported over long distances for export. The ambient conditions that the cubes may be exposed to in transit could vary from below freezing to in excess of 40°C and relative humidity up to 100%, especially when cubes are exported to humid regions of the Pacif…
The work reported here describes the water distribution patterns in sandy loam and silt loam soils under surface and micro-irrigation at different temperatures simulating the arid region conditions such as those experienced in the Balochistan Province of Pakistan. Specific consi…
Due to the shortage of measured consumptive use of water for crops (i.e., evapotranspiration, ETc) in Indonesia, estimation of reference evapotranspiration (ETo) using climatological data is necessary in order to determine crop water requirements for irrigation planning and oper…
A novel far infrared (FIR) heating system was designed and fabricated for selective heating of food powders such as soy protein and glucose. The FIR heating system consisted of six ceramic lamps, a cone-shaped waveguide, and an optical band pass filter selected according to the …
Nitrate contamination of surface and groundwater has become a serious concern in many agricultural areas throughout the world. The major source of nitrate contamination is believed to be nitrogen fertilizer from agricultural fields. Best Management Practices have been developed …
Maize is an important food and feed crop. An optimum harvest of maize requires high-quality seed. Seed-maize is harvested as ear maize at 30–35% (w.b.) moisture content in order to avoid field losses. For safe storage, it is necessary to reduce the moisture content to 12–13%. An…
This study is based on the hypothesis that shortage of dissolved oxygen at and below the water table and extraction of groundwater by irrigation wells at a rate greater than the aquifer recharge rate are the main causes of arsenic release in the groundwater of Bangladesh. The ma…
Seed furrow sidewall smearing by planter double disk openers in clay loam and loam soils was investigated in field and growth chamber experiments. Treatment variables were row preparation, soil moisture, and planting period. Evaluation parameters were soil bulk density, air perm…
