MAP is difficult to eradicate from a herd, because the pathogen persists in the environment for a long time. Upon infection with MAP, cattle undergo an asymptomatic period which can last for years. As the disease advances, an infected cow eventually becomes overtly symptomatic with decreased milk production, persistent diarrhea, and despite having no changes…
Does experiential learning focused on action actually result in improved learning outcomes
What remains a challenge both nationally and at Lowell is building optimism around our ability to solve climate change: only 8% of youth agreed that we can and will do something to mitigate climate change in a recent study , and a mere 5% of Lowell students indicated they believe their generation will solve climate…
The most common form of civic participation in UA is through volunteer activities on urban farms
Many of these efforts have potential to address many city priorities at once, for example: food access, nutrition and fitness, transportation, community development and crime reduction . Providing land access for low-income and minority farmers is an important step towards ensuring a food supply that is culturally appropriate, desirable, and marketable to food insecure urban…
There has been a proliferation of articles citing the multifaceted array of benefits attributed to urban agriculture
If the county is able to more holistically account for the value streams generated by local farms, it will become easier to justify commitment of staff and funds to support the goals of successfully transitioning, protecting, and sustaining the progress made on local farms for future generations . Tax revenues from vacation rentals, for example,…
The mobile processing unit is USDA-inspected and greatly reduces costs from transporting animals off island for slaughter
Settlers from the Midwest arrived with cattle, sheep, pigs and chickens, and by 1908 Lopez had a commercial creamery shipping 1,500 lbs of butter each month to the mainland. By the 1920s the islands reach a high in number of farms and farmland, with 566 farmers and over 68,000 acres in production, largely for homesteading…
Food systems are both impacting and impacted by the climate system
The ASI provides some criteria to examine each visual capability. For example, the ASI determined peripheral or side vision as the ability to see to the sides while looking straight ahead. The ASI provided a method to determine a youth’s side vision by looking straight ahead while moving objects to the side. The youth should see…
There is no clear evidence that on-farm practices to reduce animal intrusions are effective at enhancing food safety
Based on a closer examination of the top eight farms of each list, for every year , one list always included at least the top three elements of the other. In other words, each list contained the top three farms in terms of out degree and the top three farms in terms of outcloseness. Further iterations…
We also solved a path planning and shape optimization problem using our new formulation
The results of multiple optimizations are shown in Table 6.4, where the design space is gradually reduced. According to prior studies, positive yaw misalignment angles reduce the fatigue loads and increase the overall lifespan of the turbine blades opposed to negative yaw misalignment angles. As a result, the optimization study favors design spaces with more…
Both concentration and load are important considerations when assessing water quality constituents
Having raised a good son and daughter, now you have no more ku li to do.” The price for husked rice is low in China. In Xialongkou, the daily rice consumption of two people over the course of one year amounts to 420 jin . Taking an average rice price of between 2 RMB and…
The problems just mentioned are solved using numerical optimization algorithms
More than 150 species of microorganisms were identified in animal feces that can cause infectious diseases in humans including E. coli, Salmonella, Giardia, Campylobacter, and Cryptosporidium parvum. Some viruses in animal feces can also cause health problems to both livestock and humans. Researchers have found that E. coli O157: H7 can infect the edible part of…
