New development of beta-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties, New development of β-chitosan from jumbo squid pens (Dosidicus gigas) and its structural, physicochemical, and biological properties

Creator:: Jung, Jooyeoun
Abstract:: β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...

Effects of Preinoculation with VAM fungi isolated from different sites on plant tolerance to salinity in soils amended with sodium chloride

Creator:: Cantrell, Isabella Cardona
Abstract:: The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...

The role of innate immunity in cnidarian-dinoflagellate symbiosis

Creator:: Poole, Angela Z.
Abstract:: Cnidarians, such as corals and sea anemones serve as hosts to a variety of organisms including symbiotic dinoflagellates, bacteria, virus, and apicomplexans. As corals are vital to the health and productivity of the reef ecosystem it is important to understand how these organisms interact with each component of the holobiont....

Aryl acetylene substituent effects : the synthesis and application of biaryls

Creator:: Naffziger, Michael R.
Abstract:: The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

Development of bi-based lead-free piezoelectric materials : thin film piezoelectric materials via PVD and CSD routes

Creator:: Jeon, Yu Hong
Abstract:: Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....

Protein-protein interactions in the bacteriophage T4 dNTP synthetase complex

Creator:: Shen, Rongkun
Abstract:: The enzymes of dNTP synthesis in T4 infection associate to form a multienzyme complex, the T4 dNTP synthetase complex, facilitating the flow of metabolites en route to dNTPs, and their subsequent flow into DNA. Study of protein-protein interactions helps one to understand how the enzymes in the complex are organized...

The physiological effect of posture on cycling

Creator:: al-Haboubi, Muhammad
Abstract:: The objective of this research was to investigate the physiological effects of body posture on cycling. The familiar positions of bicycle riding have been the touring posture (hands stretched on top handlebar) and the racing posture (hands bent at the elbow, with the back horizontal). However, a relatively new stance...

A tool for visualizing sequence alignments and associating annotations

Creator:: Zhang, Wenpeng
Abstract:: Alignment of genomic sequences from different species is becoming an increasingly powerful method in biology, and is being used for many purposes. The result of sequence alignments is a list of pairs of matched locations between the pattern string and the text string. However, without any proper visualization tools to...

Continuous microwave extraction of peppermint oil

Creator:: Smith, Connor J.
Abstract:: Steam distillation has been the common method of extraction of essential oils from plants for more than a century. The use of microwave energy has been suggested as an alternative distillation method that would: reduce water usage, dependence on non-renewable energy sources, and the carbon footprint. A byproduct of this...

Oregon agricultural commodities: 2005 farmgate values and first handler value added

Creator:: Oregon State University. Extension Service, Burt, Lawrence A., and Brewer, Linda J.
Abstract:: The OSU Extension Economic Information Office annually compiles estimates of crop and livestock production and farmgate values in all 36 counties. About 70 OSU Extension and research faculty provide the estimates, based on personal knowledge, contact with industry leaders, various published and unpublished data, and, in some cases, surveys. Depending...
