Study On Removal Of Staphylococcus Aureus Biofilm By Acidic Electrolytic Oxidation Water, Yu Ming, Zhang Quankai, Luo Xiaojun, Chen Haiqiang, Yang Gongming

Food and Machinery

The removal efficiency of electrolyzed oxidizing water on biofilm of Staphylococcus aureus was studied. Electrolyzed oxidizing water showed obvious damage on the Staphylococcus aureus biofilm，including substantially destroyed external matrix, severely destroyed cells and decreased bacterial number observed with SEM（scanning electron microscope）on 5 000-times and 40 000-times. The removal efficiency could be reduced significantly by prolonging storage time of oxidation potential acidic water , raising preservation temperature and the presence of organic interfering substances. The removal efficiency of sealing preservation was superior to openning preservation. The available chlorine, pH value and redox potential had a synergistic effect on the removal efficiency. …

Loop-Mediated Isothermal Amplification Method For Detection Of Transgenic Maize Nk603, Yang Lixia

Food and Machinery

The specific LAMP primers of genetically modified maize NK603 were designed on the basis of the published sequence (GenBank accession number AX342369). Established the specific loop-mediated isothermal amplification (LAMP) method for the detection of the transgenic maize line NK603 strains. The specificity and sensitivity of this method were evaluated. The results showed that LAMP could detect the transgenic maize NK603 from several GM events specifically and effectively with LOD of 0.1%. Since this method is rapid, simple, it could be applied in GMO detection.

Antitumor And Antiangiogenic Effects Of Flavonoids, Li Xiangzhou, Luan Fangfei, Zhang Sheng, Huang Dan

Who Wants The Right To Know? An Analysis Of Gmo-Labeling In California, Sylvia M. Xu

Journal of Environmental and Resource Economics at Colby

There are many studies that have been done to examine what types of voting behavior or patterns are present when voting for environmental ballot measures. This paper examines what characteristics of people are likely to cause them to support Proposition 37 in California, an initiative that, if passed, would require GMO-labeling on all genetically modified foods. Using voting data at a zip code level, I use OLS regression to identify specifically what type of political party, education, occupation, household status, and income levels are more likely to support the bill. I also run weighted regressions by population and number of …

Hepatic Transcriptomic And Metabolic Responses Of Hybrid Striped Bass (Morone Saxatilis × Morone Chrysops) To Acute And Chronic Hypoxic Insult, Benjamin H. Beck, S. Adam Fuller, Chao Li, Bartholomew W. Green, Honggang Zhao, Steven D. Rawles, Carl D. Webster, Eric Peatman

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Striped bass (Morone saxatilis), white bass (Morone chrysops), and their hybrid are an important group of fish prized for recreational angling in the United States, and there and abroad as a high-value farmed fish. Regardless of habitat, it is not uncommon for fish of the genus Morone to encounter and cope with conditions of scarce oxygen availability. Previously, we determined that hybrid striped bass reared under conditions of chronic hypoxia exhibited reduced feed intake, lower lipid and nutrient retention, and poor growth. To better understand the molecular mechanisms governing these phenotypes, in the present study, we …

Discordant Data And Interpretation Of Results From Wildlife Habitat Models, Anita T. Morzillo, Michael G. Wing, Justin Long

Journal of Geospatial Applications in Natural Resources

Wildlife habitat management is an important part of natural resource management. As a result, there are a large number of models and tools for wildlife habitat assessment. A consequence of the many assessment tools is inconsistency when comparing results between tools, which may lead to potential confusion management decisions. Our objective was to compare results from two wildlife habitat models – one being relatively coarse (HUC5) scale and not spatially dynamic and the other being finer scale spatial data based on a 30 m spatial resolution –for habitat assessment of three species across the West Cascades of Oregon: Northern spotted …

Impact Of Irrigation Method On Water Use Efficiency And Productivity Of Fodder Crops In Nepal, Ajay K. Jha, Razan Malla, Mohan Sharma, Jeeban Panthi, Tarendra Lakhankar, Nir Y. Krakauer, Soni M. Pradhanang, Piyush Dahal, Madan Lall Shrestha

Publications and Research

Improved irrigation use efficiency is an important tool for intensifying and diversifying agriculture in Nepal, resulting in higher economic yield from irrigated farmlands with a minimum input of water. Research was conducted to evaluate the effect of irrigation method (furrow vs. drip) on the productivity of nutritious fodder species during off-monsoon dry periods in different elevation zones of central Nepal. A split-block factorial design was used. The factors considered were treatment location, fodder crop, and irrigation method. Commonly used local agronomical practices were followed in all respects except irrigation method. Results revealed that location effect was significant (p < 0.01) with highest fodder productivity seen for the middle elevation site, Syangja. Species effects were also significant, with teosinte (Euchlaena mexicana) having higher yield than cowpea (Vigna unguiculata). Irrigation method impacted green biomass yield (higher with furrow irrigation) but both methods yielded similar dry biomass, while water use was 73% less under drip irrigation. Our findings indicated that the controlled application of water through drip irrigation is able to produce acceptable yields of nutritionally dense fodder species during dry seasons, leading to more effective utilization and resource conservation of available land, fertilizer and water. Higher productivity of these nutritional fodders resulted in higher milk productivity for livestock smallholders. The ability to grow fodder crops year-round in lowland and hill regions of Nepal with limited water storages using low-cost, water-efficient drip irrigation may greatly increase livestock productivity and, hence, the economic security of smallholder farmers.

Conservation Agriculture: Gendered Impacts On Households' Livelihoods, Olipa Zulu-Mbata, Antony Chapoto

Zambia Social Science Journal

In response to climate change, new technologies resilient to climatic variability have been promoted among smallholder farmers. Conservation Agriculture (CA) has been promoted since the 1990s in sub-Saharan Africa. However, as with any new technology, various factors affect adoption and ultimately the impact of the technology. Gender is one such factor. Both female and male smallholder farmers are faced with numerous constraints to accessing productive resources. Female farmers face more problems in adopting new technology than do male farmers, resulting in few of them adopting them. This in turn reduces the impact that these technologies have on their livelihood. Using …

High Throughput Genomic Sequencing Of Bioaerosols In Broiler Chicken Production Facilities, Kate M. O’Brien, Michael S. Chimenti, Morgan Farnell, Tom Tabler, Thomas Bair, Joey Lynn Bray, Matthew W. Nonnenmann

Faculty Publications

Chronic inhalation exposure to agricultural dust promotes the development of chronic respiratory diseases among poultry workers. Poultry dust is composed of dander, chicken feed, litter bedding and microbes. However, the microbial composition and abundance has not been fully elucidated. Genomic DNA was extracted from settled dust and personal inhalable dust collected while performing litter sampling or mortality collection tasks. DNA libraries were sequenced using a paired-end sequencing-by-synthesis approach on an Illumina HiSeq 2500. Sequencing data showed that poultry dust is predominantly composed of bacteria (64–67%) with a small quantity of avian, human and feed DNA (< 2% of total reads). Staphylococcus sp. AL1, Salinicoccus carnicancri and Lactobacillus crispatus were the most abundant bacterial species in personal exposure samples of inhalable dust. Settled dust had a moderate relative abundance of these species as well as Staphylococcus lentus and Lactobacillus salivarius. There was a statistical difference between the microbial composition of aerosolized and settled dust. Unlike settled dust composition, aerosolized dust composition had little variance between samples. These data provide an extensive analysis of the microbial composition and relative abundance in personal inhalable poultry dust and settled poultry dust.

Determining The Value Of Birthrank And Parent Age In Thoroughbred Racehorses, Xiurui Cui

Theses and Dissertations--Agricultural Economics

Thoroughbred racing is referred to as “the sport of Kings”, because historically it was a leisure activity of the upper-class. Thoroughbred breeding on the other hand has transformed from a hobby of the upper-class to a worldwide agricultural industry. With the deep involvement of the royal and rich in the Thoroughbred industry, the auction prices of horses are raised significantly at the top end of the market.

Research in the biological sciences suggests there exits correlations between dam age, foal birthrank, and the racing performance of Thoroughbred horses. This study first investigates how the market values these biological factors and …

Economic Considerations Of Aggressively Treating The Influenza Virus In Equines, Charlotte R. Hansen

Theses and Dissertations--Agricultural Economics

The equine influenza virus is a significant cause of respiratory disease in horses. Even though horses generally recover from this virus, sometimes horses with equine influenza develop secondary bacterial infections which can cause severe pneumonia, thereby increasing recovery times. Owners and managers are faced with the decision of whether to delay preventative treatment in hopes of the horse avoids contracting a secondary bacterial infection (“wait and see”) or aggressively treat the horse with an antibiotic in hopes of avoiding a serious infection (“treat now”). From a decision making standpoint, the economic considerations include explicit treatment costs as well as nonmonetary …

Understanding The Molecular Mechanisms Underlying Rsv1 Mediated Resistance To Smv In Soybean, Mohammed Ali Ahmed Eid

Theses and Dissertations--Plant Pathology

Like humans, viral diseases also affect plants. Of these, viruses belonging to the potyvirus genus are the most prolific. The potyvirus soybean mosaic virus (SMV) is an important pathogen of the crop plant soybean. SMV causes mosaic symptoms (yellow areas alternate with dark green areas on the leaves of the plant) and can affect yield by reducing seed quality. Few cultivars from soybean can resist different SMV strains. To understand soybean defense mechanisms to SMV, I identified soybean proteins that interact with the helper component protease (HC-Pro) of SMV, which also functions as the suppressor of host RNA silencing and …

Investigating Ichneumonidae: Insights Into Species Identification And Venom Composition, Victoria G. Pook

Theses and Dissertations--Entomology

Parasitoid wasps are hyperdiverse, with current estimates suggesting that they may account for up to 20% of all insect species. Though their ecological significance and their importance in integrated pest management cannot be denied, these taxa remain understudied and, due to their small size, are often overlooked. However, recent advances in molecular techniques are helping to reverse this trend by providing tools which scientists can use to better understand species limits and host interactions.

Parasitoid wasps are often morphologically cryptic and their accurate delimitation requires the analysis of DNA sequence data from fast-evolving genes in addition to morphological characters. The …

Correlating Bulk Density (With Dockage) And Test Weight (Without Dockage) For Wheat Samples, Rumela Bhadra, Mark E. Casada, Josephine M. Boac, Aaron P. Turner, Sidney A. Thompson, Michael D. Montross, Ronaldo G. Maghirang, Samuel G. Mcneill

Biosystems and Agricultural Engineering Faculty Publications

In grain bins, the compaction of stored grain is caused by the overbearing pressure of the bulk material in the bin. To predict the amount of grain in the bin, compaction values must be determined based on the average bulk density (BD) of the stored material. However, BD is determined following the Federal Grain Inspection Service (FGIS) guidelines for measuring test weight (TW), which require that dockage be removed prior to measuring wheat TW. Thus, this creates a problem for predicting grain compaction and conducting inventory studies, because the average BD of the grain in a bin for these calculations …
