Corncob Grit Application as an Alternative to Control Weeds in Two Crop Production Systems
… yield of an integrated air-propelled abrasive corncob grit (for in-row weed control) at varying timings and frequencies and flame-weeding or cultivation (for between-row weed control) system in two corn production systems. In the first study efficacy of weed control was assessed with this …

Visualizing fluidized beds with X-rays
… of glass beads, ground walnut shell, and ground corncob operating with a variety of flow conditions. 3-D local, time-averaged gas holdup is calculated from CT data, while dynamic features are captured by X-ray stereography. The results show that CT is most effective on glass bead fluidized beds. …

Design and testing of a microbial fuel cell for the conversion of lignocellulosic biomass into electricity
… using a solid, lignocellulosic substrate (corncob pellets) as the electron donor. The first trial, using a prototype reactor with a graphite rod anode, ran for 415 hours, and generated a maximum open circuit voltage and current of 0.67 V and 0.25 mA, respectively. The second trial employed …

Creating a low-cost, low-particulate emissions corn cob charcoal grinder for use in Peru
… using agriculture wastes such as bagasse and corncobs. However, it has been found that corncob charcoal produces dangerously high levels of carbon monoxide and as a result is unable to be burned directly and must be briquetted. In conjunction with this, an organization in Lima, Peru called …

Improving performance and expanding application of denitrifying bioreactors for nutrient management in agricultural landscapes
… study (Chapter 3) evaluated the performance of corncob (CC) versus woodchip (WC) bioreactor media across a range of flow conditions and identified key drivers of performance. Results demonstrated that CC consistently outperformed WC, achieving greater nitrate removal efficiency (NRE) and NO3 …

Hydrodynamic Characterization of 3D Fluidized Beds Using Noninvasive Techniques
… varied between three bed materials (ground corncob, crushed walnut shell, and glass beads) of the same size, and over four and five relative superficial gas velocities and side-air injection gas flow rates respectively. The fourth objectives mirrored the third, however, did not use side-air …

Design of silica-based sustainable biomaterial adsorbents from agricultural waste for the microextraction and adsorptive removal of insecticides and antibiotics from wastewater samples
… agricultural wastes such as palm fronds, corncobs, and sugarcane bagasse into silica-based magnetic nanocomposites (Fe3O4@SiO2), thereby converting low-value biomass into functional adsorbents while reducing waste disposal burdens. Guided by green chemistry principles, these cost-effective …

Kongo to Kings County
… was a diKenga symbol made out of one whole corncob and one that was broken into two pieces to form the two vertices of an ‘X’. Many of the items in this assemblage are similar to items that would be placed into a N’Kisi in Western Africa and are also found at various places around the the …

Influence of a Biodegradable Litter Amendment on the Pyrolysis of Poultry Litter
… (AmmoSoak), developed from steam exploded corncobs, to poultry litter prior to pyrolysis on the product yields and qualities were investigated. Mixtures of litter and AmmoSoak were pyrolyzed in a bench-scale fluidized bed reactor. The objective of the second phase was to start-up a …
