The size and velocity characteristics of droplets in agricultural sprays generated from two flat fan nozzles were studied in a wind tunnel using a Phase-Doppler Particle Analyzer. A sheared cross flow pattern, having lower velocities near the wind tunnel floor and increasing vel…
A methodology is presented along with an expert system program for evaluating the impact of animal traction at the farm level in a small-scale multi-cropping system. In its actual version, the expert system program applies to oxen cultivation using Ndama species in the Basse Cas…
The performance of irrigation systems in many parts of the world is generally perceived to be poor compared to design intentions and investment expectations. Lack of good water management causes this. Data covering climatology, pedology, agriculture and management, commonly coll…
Agro-climatological study of four states in the Savannah Middle Belt of Nigeria have been carried using 62 stations. Daily rainfall data of these stations, with at least 10 years of record from 1916-1990, were obtained from the Climate Change Center of the Federal University of …
Scope and methods of study. (1) Scale effects on phosphorus (P) loss and runoff depth from pastures were investigated by summarizing water quality data from 19 research projects. Spatial (area) and temporal (days after litter application) scales ranged from 0.5 to 80000 m2 and 1…
Knowledge of the plant availability of P from manures is important for the proper management of poultry wastes. The purpose of this research was to investigate the effect of previous history of waste applications on the plant availability of poultry waste P. The first phase of t…
An extensive literature review and comparative analysis of heat and moisture production (HP, MP) of various poultry types (layers, broilers, and turkeys) and their housing systems indicated that total heat production (THP, W/kg) has increased over the years by about 15 to 44% (1…
The USDA-FSIS recently amended the regulations governing cooked meat and poultry products, creating a shift to lethality performance standards, and a need for inactivation models. Studies clearly show that many factors affect thermal inactivation of pathogens; however, water has…
The main objectives of this research were to: (1) Estimate plant growth parameters for GRASIM using numerical optimization procedures while enforcing plant physiological constraints; (2) Simulate the competition between coexisting forage species for light, water and nutrients an…
Groundwater contamination has many sources, the routine agricultural application of fertilizers and pesticides are recognized as significant sources. This field study was initiated and designed to evaluate if there were differences among different irrigation technologies on wate…
A predictive model for moist-air impingement cooking of ground-and-formed meat and poultry products was developed. A coupled heat and mass transfer model incorporating the effects of fat transfer was combined with a model for Salmonella inactivation, to produce a complete predic…
Weak organic acids and/or their salts were tested as soil washing or flushing agents for the ex- or in-situ remediation of soils polluted by heavy metals. Three soils naturally with heavy metals were used for the tea. The three soils were characterized as a clay loam, loam and s…
Major meat quality problems of three species are addressed. Fiber optics, electrical conductance, and image analysis were employed in the evaluation or prediction. (1) Evaluation of longissimus dorsi marbling in intact pork (n = 37) and beef (n = 10) carcasses with a fiber optic…
Quality defects in fresh fruits and vegetables have adverse effects on the market value of the products. Increased consumer awareness of product quality has made the marketing of fresh fruits and vegetables so competitive that maintaining high quality is essential to economic su…
This study of rainfall distribution in West Timor is concerned with the analysis of temporal and spatial rainfall characteristics, regional frequency analysis of annual daily maximum rainfall and pentad (5-days) drought analysis. Several statistical properties such as persistenc…
The Fordwah Eastern Sadiqia South (FESS) Irrigation and Drainage Project in Pakistan's Punjab Province is beset by debilitating soil waterlogging and soil salinization. Phase-One of the FESS Project was designed to explore management alternatives to lower groundwater, reduce soi…
Salmonella and other pathogenic organisms that infect poultry and other livestock can originate from feed or the environment. Technologies to control Salmonella infection in poultry are important measures taken to reduce turkey and poultry production losses. A study was designed…
The thesis describes the development of an electrical immunoassay (EI) biosensor for detecting foodborne pathogens. The biosensor consists of two components: an immunosensor that is based on an electrical sandwich immunoassay and a reader for signal measurement. The architecture…
