Scientists at NDSU have developed a method for predicting and/or confirming the success of pregnancy and/or litter size in mammals as well as devices for field testing of mammal samples for pregnancy success and reproduction prosperity (fecundity). Measuring hematocrit levels or blood oxygen saturation near the time of insemination of a mammal can indicate the likelihood of a successful pregnancy and also predict litter size. These methods can also be used to confirm a successful pregnancy sooner than other methods.
The majority of biomass polymers, when broken down into their constituents, consist of cellulose derived sugars of 5 or 6 carbon atoms and lignin-derived aromatic building blocks. These building blocks are relatively highly oxidized and thus, without further chemical conversion, are not well-suited for fuels and chemicals. Scientists at NDSU have recently invented novel methods for the conversion of renewable resources to feedstock chemicals. The lignin and cellulose degradation products are converted to higher quality monomers through certain chemical reactions for use in polymer synthesis.
Scientists at NDSU have mapped the putative protective and non-protective regions of the PCV2 capsid protein. The key concept for this disclosure is that eliminating or altering the non-protective regions resulted in creation of negative selection markers for the development of the DIVA immunoassay. Additionally, removal of non-protective regions to rationally redesign the antigen is expected to improve vaccine efficacy against both PCV2a and b subtypes and reduce viral shedding, when compared to exisitng vaccines.
Scientists working at NDSU are developing biodegradable sensors capable of directly monitoring and reporting the soil environment in which they are placed. The sensors are constructed by using NDSU’s patent-pending “direct write” electronic printing techniques to print circuit and antenna patterns directly onto renewable, bio-based materials. The circuit patterns are printed with trace amounts of metallic materials such as aluminum that are safe for the soil when the sensors naturally biodegrade over time.
Scientists at NDSU have developed a technology that removes selenium, arsenic, trichloroethylene and phosphorus from water using beads containing reactive nano zero valent iron (nZVI) particles encapsulated in calcium alginate beads. When charged with phosphorus or selenium, these beads can be beneficially reused to provide phosphate and/or micronutrient fertilization. Therefore, the technology provides dual benefits of cleaning eutrophic and contaminated water bodies and waste streams, while collecting some of the contaminants (selenium and phosphate) with the potential of reuse in a form that facilitates this reuse.
Scientists at NDSU have developed biodegradable iron-containing alginate beads that remove phosphorus from water, and can then be beneficially reused to provide Phosphate fertilization. As a result, this dual-use technology can be used to clean water bodies that are eutrophic due to excess phosphorous, then use the phosphorous for fertilization in agricultural, nursery, and greenhouse settings where phosphorus is a limiting nutrient.
The extremely high surface area of nanoparticles provides many advantages over conventional particles with dimensions in the micron scale. For a variety of applications, it is necessary to suspend the nanoparticles in a liquid medium. Researchers at NDSU have developed a new plant-oil-based polymer technology focused on the application of nanoparticle suspension in water.
Fast, reliable, nondestructive means of measuring sugar content of sugar beets during harvest.
An optical sensor for use in measuring constituents of an agricultural product. An optical sensing window passes a stream of the agricultural product, and a radiation source irradiates the stream as it passes through the optical sensing window. A receiver receives radiation transmitted through the stream and converts it into a corresponding electrical signal using a spectrometer. The electrical signal is digitized to produce a series of data points corresponding to particular wavelengths. A processor normalizes the data points using a reference value in order to generate processed data points that can be used to predict a constituent content of the agricultural product.
Scientists at North Dakota State University have cloned and sequenced the iss (increased serum survival) gene from virulent avian Escherichia coli strains and expressed its encoded ISS polypeptide sequence. This has enabled them to conduct studies in understanding the gene’s potential and devise strategies to detect and control the colibacillosis infection that the gene is believed to cause.
