SPECIFICATION DEVELOPMENT FOR THE USE OF DEVON COB IN EARTHEN CONSTRUCTION
The traditional earthen building practice of cob construction has been historically linked to Devon for many centuries. However no standards or specifications exist to facilitate a technical appraisal of the material. This thesis sets out to develop an appropriate test methodology for the …

Integration of a cob separation system into a biomass harvesting combine
… later. This led to an availability of corn cobs and many uses were found. A renewed interest in the heat/energy value of the cob has increased the focus on harvesting corn cobs. A corn cob separation system was developed and installed on a single pass biomass harvesting combine. The system …

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 Enlace …

Assessing low thermal conductivity of bricks which contain rice husk, corn cob and waste tea as an additive material
Energy efficient buildings have emerged as a new approach to encourage use of natural resources and reduction of energy requirements. Thermal and mechanical brick properties play an important role in designing modern buildings. Decreasing thermal conductivity is the dominant factor in reducing heat …

Investigation on the Mechanism of Formation and Consumption of Vinylcobalamins Involved in Vitamin B(12)-Catalyzed Reductive Dechlorination of Perchloroethylene
Similar experiments were undertaken using cobalamins to further investigate the vitamin B12-catalyzed dechlorination of PCE. Chlorovinylcobalamin 16, previously detected in the PCE dechlorination reaction, was synthesized by treating cob(I)alamin with chloroacetylene. The structure of 16 was …

Organic Fillers in Phenol-Formaldehyde Wood Adhesives
… regia), alder bark (Alnus rubra), and corn cob (furfural production) residue. Alder bark and walnut shell exhibited chemical compositions that are typical for lignocellulosic materials, whereas corn cob residue was distinctly different owing to the high pressure steam digestion used in its …

Cache-oblivious dynamic search trees
… structure". We refer to the data structure as a COB-Tree. The COB-Tree supports efficient lookup, as well as efficient amortized insertion and deletion. Efficient implementation of a B-tree requires understanding the cache-line size and page size and is optimized for a specific memory hierarchy. …

Translationsaktivatoren der mitochondrialen Cytochrom b-Synthese in Saccaromyces cerevisiae: Membranassoziation, Mutagenese und Protein-Wechselwirkungen von Cbs1p
… zwei spezifische Translationsaktivatoren der COB-mRNA. Im Mittelpunkt standen sowohl die weitere molekularbiologische und biochemische Charakterisierung von Cbs1p als auch ein Screening von Interaktionskandidaten, die mit Cbs1p und/oder Cbs2p physikalisch wechselwirken könnten. Cbs1p liegt als …

Rheology And Organic Filler Interactions in Phenolic Resin Formulations
… waste products like walnut shells and corn-cob residue. These organic waste products act as fillers that reduce the cost, increase the viscosity, and affect the rheology of the fillers. Wheat flour is added as an extender to reduce cost and affect the tack of the adhesive. These organic …

Maize ear rot and associated mycotoxins in western Kenya
… was established as the most important crop and cob rot as the most important crop protection problem in Western Kenya. The mean percentage rotten maize grain resulting from cob rot was 19% based on the PRA survey in Kapsabet and Tongaren Divisions and on-farm evaluation of the Kenyan hybrids in …

Estimating Spot Price and Smooth Forward Curve in Electricity Markets with Bayesian Penalized Spline
… (Mid-C) and California Oregon Border (COB) pricing hubs. Since Mid-C is a liquid market where forward contracts are quoted every day and COB is an illiquid hub, a two step estimation procedure is developed from Bayesian perspective.First, the Mid-C smooth curve is constructed using …

Novel Synthesis of Bulk Nanocarbon (BNC)
… ball milling and the carbonization of corn cob. Corn cob was mechanically milled for up to 20 hours by applying high energy ball milling to produce the milled powder. The milled powder was cold-compacted and carbonized at up to 1500°C to fabricate the BNC material. The material revealed both …

The Synthetic spider silk fibers spun from Pyriform Spidroin 2, a glue silk protein discovered in orb-weaving spider attachment discs
… to the other silk family members, including the cob weaver glue silk fibroin PySpl. PySp2 contains internal block repeats that consist of two sub-repeat units: one dominated by Ser, Gin and Ala, the other Pro-rich. Artificial spinning of recombinant PySp2 truncations shows that the …

Mechanistic Studies of Vitamin B(12)-Catalyzed Dechlorination and Carbon-Carbon Bond-Forming Reactions
… recombination of alkyl radicals with cob(II)alamin. The mechanism of the formation of benzylic radicals from arylalkenes and cob(I)alamin poses an interesting problem. The results with a one-electron transfer (et) probe indicate that the radical generation is not likely to involve an …

Organ-specific regulation and molecular evolution of the maize pericarp color1 gene
… floral organs, most notably kernel pericarp and cob. Alleles of the p1 gene condition distinct tissue-specific pigmentation patterns. To elucidate the molecular basis of these allele-specific expression patterns, we characterized two novel P1-rw alleles, P1-rw1077 and P1-rw751::Ac. Structural …
