Conjunctival Hemangiosarcoma In A Female Dog: Case Report, Felipe Gaia De Sousa, Suzane Lilian Beier, José Antônio Da Cruz Neto, Natália Fagundes, Isaac Scherre Lubiana, Alaine Cristina De Andrade

Revista de Medicina Veterinaria

Los hemangiosarcomas son tumores de origen mesenquimatoso, potencialmente deletéreos, asociados a áreas de alta vascularización. La progresión y el crecimiento del tumor están asociados con la capacidad de estos tumores para retener sangre y dar lugar a vasos sanguíneos tortuosos. Estos tumores tienen una gran capacidad metastásica, presentándose a menudo en órganos como el bazo, el hígado y la arteria aorta. Sin embargo, otros sitios pueden verse afectados, aunque con menor frecuencia, como el tercer párpado, la conjuntiva y las regiones cutáneas. El objetivo de este artículo es reportar el caso de una perra de 8 años de edad con …

Are Too Many Or Too Few Babies Being Born?, Wesley Peterson

Cornhusker Economics

An additional 1.8 billion people will be added to the world’s population by 2050. At the same time, average incomes are likely to rise. Data from the Groningen Growth and Development Center suggest that average real (inflation-adjusted) GDP per capita increased by a factor of fifteen between 1820 and 2018 and World Bank data indicate that real per capita GDP more than tripled over the past 62 years. It is likely that these trends will continue and there will be more people with higher average incomes in the future straining global food systems and natural resources. Slower population growth rates …

Growing Agriculture Literacy’S Presence In America’S Classrooms, Emily Stone

Journal of Food Law & Policy

“Americans, as a whole, were at least two generations removed from the farm and did not understand even the most rudimentary of processes, challenges, and risks that farmers and the agricultural industry worked with and met head-on every day.” This quote perfectly describes the mindset of agriculture stakeholders in 1981 as they began to realize the drastic steps our education system had taken away from using principles of agriculture in K-12 education. As they saw it, Americans were moving out of rural America, away from farms, and becoming less connected to the food they daily consumed. Simultaneously, the education system …

Texcot22, Md Ahmed Al Muzaddid, William J. Beksi

Computer Science and Engineering Datasets

The TexCot22 dataset is a set of cotton crop video sequences for training and testing multi-object tracking methods. Each tracking sequence is 10 to 20 seconds in length. The dataset contains of a total of 30 sequences of which 17 are for training and the remaining 13 are for testing. Among the training sequences, 2 of them consist of roughly 5,000 annotated images, which can be used to train a cotton boll detection model. The video sequences were captured at 4K resolution and at distinct frame rates (e.g., 10, 15, 30). There are typically 2 to 10 cotton bolls per …

Crop Classification In South Korea For Multitemporal Planetscope Imagery Using Sfc-Densenet-Am, Seonkyeong Seong, Anjin Chang, Junsang Mo, Sangil Na, Hoyong Ahn, Jaehong Oh, Jaewan Choi

Agricultural and Environmental Sciences Faculty Research

In this manuscript, a new methodology based on a deep learning model using a Siamese network and attention module was proposed to classify crop cultivation areas, such as onion and garlic, from multitemporal PlanetScope images in South Korea. To consider the seasonal characteristics of crops in the model, training data were constructed from multitemporal satellite images. It was generated using PlanetScope satellite imagery from January and April, corresponding to the seasonal growth period of onion and garlic, in South Korea. Image patches were generated by considering the ratio of crops to minimize the influence of imbalanced data in the training …

2023 Evaluation Of Pumpkin Cultivars In West Virginia, Lewis Jett

Midwest Vegetable Trial Reports

Pumpkins are a popular, commercial vegetable crop in West Virginia. Each year, many new hybrid cultivars are released by commercial seed companies. In 2023, we trialed 16 cultivars. Pumpkins were grown using conventional tillage, and each cultivar was replicated 4 times. ‘Griffin’ ‘Justify’, ‘Hawk’, ‘Bellatrix’ and ‘Hermes’ produced high yields with both fruit count and average weight per pumpkin.

Plum Curculio (Conotrachelus Nenuphar), Kate V. Richardson, Marion Murray

All Current Publications

Plum curculio is a brown weevil (beetle with a snout) native to eastern North America, where it is a major pest of pome and stone fruits. It was detected in Box Elder County, Utah, in the early 1980s, and this population remains the only known infestation in western North America, where it is occasionally found in residential and wild fruit trees. Plum curculio is a quarantine pest in western North America (U.S. and Canada), and fruit grown in infested counties is restricted from being exported. Thus, it is a threat to Utah’s fruit industry and requires ongoing monitoring and management …

Perceptions Of Available Funding Opportunities For West Tennessee’S Young And Beginning Row Crop Farmers, Logan Meeks

Murray State Theses and Dissertations

Research quickly identified many different avenues of funding available to new and beginning traditional row-crop farmers in Tennessee, but questions surrounding local farmers’ knowledge of these opportunities are in question. Many programs specific to the New and Beginning Farmer demographic boasted the potential benefits of using these programs as well as the good work these programs are accomplishing. The current increase in cost of traditional row-crop funding continues to drive the need for more funding resources with New and Beginning Farmers. Providing resources of where farmers can find the best available funds for their operation will expand the level of …

Perennializing Marginal Croplands: Going Back To The Future To Mitigate Climate Change With Resilient Biobased Feedstocks, Salvador Ramirez Ii, Marty R. Schmer, Virginia L. Jin, Robert B. Mitchell, Catherine E. Stewart, Jay Parsons, Daren D. Redfearn, John J. Quinn, Gary E. Varvel, Kenneth P. Vogel, Ronald F. Follett

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

Managing annual row crops on marginally productive croplands can be environmentally unsustainable and result in variable economic returns. Incorporating perennial bioenergy feedstocks into marginally productive cropland can engender ecosystem services and enhance climate resiliency while also diversifying farm incomes. We use one of the oldest bioenergy-specific field experiments in North America to evaluate economically and environmentally sustainable management practices for growing perennial grasses on marginal cropland. This long-term field trial called 9804 was established in 1998 in eastern Nebraska and compared the productivity and sustainability of corn (Zea mays L.)—both corn grain and corn stover—and switchgrass (Panicum virgatum …

Research Report: Radicchio Cultivar Performance In New Hampshire, Rebecca G. Sideman, Ella Lukacz, Lilly Hartman

Faculty Publications

Radicchio (Cichorium intybus var. latifolium) is grown widely throughout Europe, especially northern Italy. In addition to having interesting color and flavor profiles, they are rich in phenolics and other bioactive compounds. While increasingly popular as a niche vegetable in the region, there is little research-based information to guide growers. The New England growing climate is very different from that of major production regions, and it presents unique challenges. There is tremendous phenotypic variation among and within groups and cultivars. The availability of varieties to commercial growers in the U.S. has expanded greatly, but there remains a need for reliable …

Autism In Agricultural Education: A Case Study Of An Adolescent With Autism Spectrum Disorder And Their Parent On Career And Technical Education, Grace Miller

Theses and Dissertations--Community & Leadership Development

Autism spectrum disorder (ASD) is a unique and often misunderstood diagnosis. Little is known about the experiences of adolescents with ASD. As students with ASD graduate high school, many are under- and unemployed. Career and technical education (CTE) in U.S. schools is intended to prepare all students for careers post-secondary. Agricultural education is one of the predominate career clusters within CTE. This qualitative single case study sought to create a platform for both a student and their parent to share their experiences in agricultural education and CTE. Participants were an adolescent with ASD who had taken at least one year …

The Effect Of Biochar From Plant Materials On Agricultural Acid Sulfate Soil: A Laboratory Incubation, Syazwan Sulaiman, Namasivayam Navaranjan, Guillermo Hernandez-Ramirez, Zohrah Sulaiman, Kathereen Liew

ASEAN Journal on Science and Technology for Development

The scarcity of suitable arable land has led to the development of acid sulfate soil for cultivation. The major problems of acid sulfate soil are the inherent low pH and available phosphorus (P) as well as the mobilization of toxic elements such as aluminium (Al) and iron (Fe), rendering the soil unfavourable for crop production. The present work aimed to evaluate the effect of biochar from plant materials on the selected parameters of acid sulfate soil in a laboratory incubation, with unamended control and dolomite treatment soils for comparison. The application of biochar significantly increased (P < 0.05) soil pH by 0.4-0.6 units as well as the soil available P by 13.1 mg kg-1 relative to the control. The soil exchangeable Al was significantly reduced (by 2.4 cmol kg-1 when compared with the control treatment. The dolomite treatment was superior relative to biochar application in increasing soil pH and decreasing Al. The dolomite application, however, was inferior to biochar treatment in increasing soil available P. Moreover, no favourable change was observed in available Fe with the applications of either biochar or lime. These results indicated that biochar has the potential for the amelioration of acid sulfate soil, especially in increasing available P. Further studies should explore the effectiveness of biochar and lime co-application in altering a wider range of soil chemical parameters to inform management options of acid sulfate soil for cultivation.

An Agroecological Approach To Improving Soil Health Practices On Vermont Vegetable Farms, Rebecca Reed Maden

Graduate College Dissertations and Theses

Vermont’s vegetable farms are highly valued for their contributions to the state's food system, environment, and communities, yet their continued success is impeded by many challenges. Specifically, soil is a valued and vulnerable resource, but management of it requires knowledge, money, and time. This dissertation applies an agroecological approach to understanding soil health practices on vegetable farms in three distinct studies.

In the first part of this dissertation, data is collected from six on-farm research trials in 2017-2018 to better understand the nitrogen (N) dynamics following two commonly planted legume-grass cover crop mixes: field peas (Pisum sativum, var. ‘4010’) and …

Assessing Endophyte Frequency Distributions And The Effect Of Epichloë Brachyelytri In The Chemotypic And Genotypic Diversity Of Brachyelytrum Erectum, Rachel Ann Sneed

Theses and Dissertations--Plant Pathology

Seed-transmissible epichloid fungal endophytes are best known for their roles as defensive mutualists in cool-season grasses. Historically, the discovery of fungal endophytes was driven by investigations of plant toxicity to livestock, followed by extensive study of their alkaloids and protection against insects and nematodes. Epichloae can produce four classes of alkaloids: ergot alkaloids, lolines (saturated aminopyrrolizidines), indole–diterpenes, and peramine. It is increasingly evident that these hereditary symbionts have much more diverse chemical profiles both in individual populations and between them. To this end, differences in chemotypic profiles of these symbionts may translate to different evolutionary and environmental advantages across plant …

Environmental Implications Of Modern Food Production: An Analysis For The Conscious Consumer, Jessica T. Coming

Cal Poly Humboldt theses and projects

This project explores the pathways by which agriculture affects the environment and determines which foods have the greatest climate, water, and land impacts. Agricultural effects on the environment are extensive, from loss of habitat and declines in regional biodiversity to disruption of global nutrient cycles and climate change. Global food production accounts for 26-34% of annual anthropogenic greenhouse gas emissions, makes up 38-46% of habitable land, and is responsible for 70% of freshwater extraction. The effect of agriculture on the environment is most significantly dictated by what type of food is being produced. Animal-based food products consistently have the highest …

Agricultural Groundcover Update December 2023, Justin Laycock

Natural resources published reports

Summary

• About 96% of the grainbelt had adequate vegetative groundcover (more than 50%) to prevent wind erosion in December 2023.
• In the northern half of the grainbelt, a larger-than-average area has 51–60% groundcover, which is expected to decrease to below 50% over the summer.
• Just under 4% of the grainbelt (553,000 ha) had less than 50% groundcover, which is inadequate to prevent wind erosion. West Midlands Ag Soil Zone had the highest risk of wind erosion and 11.4% of this farmland had inadequate groundcover.
• Less than 0.5% of the grainbelt had a high to very high risk of wind erosion …

That’S Not In My Position Description: A Discourse Analysis Of Sbae Migratory Context, Becky Haddad, Jonathan Velez, Josh Stewart, Haden Botkin

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

While the choice to move to a new school is personal, many play a role in justifying that choice for the mobile teacher. These justifiers—or influencers—make up the socializing network for teachers (in this case, SBAE teachers) in new settings. Our study outlined how mobile SBAE teachers rationalize the choice to change schools and validate career moves. We used a positioning theory approach to discourse to give migrators (teachers who change schools) and influencers a voice. Positioning theory allowed us to situate migrators as they reflected on their choice to change school districts, and influencers as they recounted their …

Measuring Mobility: A Quantitative Description Of Sbae Teacher Mobility In Minnesota, Becky Haddad, Lavyne L. Rada, Amy R. Smith

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

Considerations around teacher attrition, supply and demand, and retention are incomplete without including teacher mobility. The problem, as it currently stands, finds SBAE ill-equipped, at the professional level, to support mobile teachers. Providing support, however, starts with understanding the population; in this case, mobile teachers. The purpose of our study was to quantitatively describe teacher mobility in [State] over the last 20 years (1999-2021). To describe SBAE teacher mobility in our state, we utilized teacher retention data compiled from state teacher directories over the last 20 years (1999-2021). We corroborated previous findings noting heightened attrition after year one in a …

Implementing Integrated Stem Forensic And Soil Sciences Lab Activities To Promote Interest In Stem Careers, Mariah K. Stollar Awan, Caroline J. Rakowski

Indiana STEM Education Conference

We implemented forensic and soil science integrated STEM lab activities with 11 middle school youth at a 4-H day camp at Purdue University. STEM perceived knowledge increased overall for participants. However, the pre- and post-assessments did not show a statistically significant difference. More students also indicated STEM career interest after participating. Because this study was exploratory and had a small sample size, more research on these integrated STEM lab activities should be conducted with larger samples.
