Alternatives For Whey Protein Powder, Alleyah Murphy, Emily Jensen, Jaiden C., Spencer C.

Student Research Symposium

Protein shakes have become a popular product in the market, heavily advertised as convenient nutrient sources for active adolescents and adults. These products are widely available in grocery stores, pharmacies, and through online distributors (Deutch, 2022). Typically made with whey protein, they are unsuitable for individuals following vegan or lactose-free diets. The goal of this experiment is to evaluate the impact of substituting whey protein powder with equivalent amounts of pea, soy, and hemp seed protein powders on the taste, texture, viscosity, and protein content of vanilla protein shakes to identify the most suitable alternative

Elements Of Design In Frank Lloyd Wright’S Usonian Architecture, Jillian Ereú

Student Research Symposium

“The word “Usonian” (United States of North America) is attributed to writer James Duff Law, who wrote in 1903, “We of the United States, in justice to Canadians and Mexicans, have no right to use the title ‘Americans’ when referring to matters pertaining exclusively to ourselves.” Wright referenced this quote, misattributing it to writer Samuel Butler in Architecture: Selected Writings 1894–1940: “Samuel Butler fitted us with a good name. He called us Usonians, and our Nation of combined States, Usonia.”” (Wright, 2017)

These environments not only benefit young patients and their families but also improve the overall well-being and performance of healthcare staff by reducing stress, increasing job satisfaction, and promoting a more supportive workplace …

The Impact Of Light And Color On Child-Friendly Spaces, Moriah Martin

Student Research Symposium

Light and color significantly affect children's sleep, cognition, mood, and overall health. Proper design can enhance emotional stability, learning outcomes, and physical well-being. This research explores how light quality—brightness, saturation, and hue—along with color psychology, influence behavior, cognitive function, and circadian rhythms. Natural light improves focus, sleep, and mood, while artificial lighting must be carefully balanced to prevent disruptions. Warm colors foster energy and engagement, while cool tones promote relaxation and concentration. Findings highlight the importance of evidence-based lighting and color strategies in educational and childcare settings, ensuring environments that support children's holistic development.

Using Biophilic Design To Improve Behavioral Healthcare Environments, Rachel Tuft

Student Research Symposium

One in five U.S. adults – more than 50 million people – experience a mental health episode every year and more than 11% of children are considered severely depressed (Mental Health America). These alarming statistics are rapidly increasing the demand for behavioral healthcare environments. Yet many of these spaces remain sterile, institutional, and lack the warmth and comfort patients need for effective healing. Research shows that as people spend more and more time indoors the lack of connection to nature in contemporary-built environments is negatively impacting human well-being, leading to increased stress, reduced focus, and slower healing. Studies suggest that …

Estimation Of The Possibility Of Use Of Some Species Of Grasses For The Direct Sowing In Sward, F Bukowiecki

IGC Proceedings (1977-2023)

One of the ways of counteracting the degradation of meadow plant communities is the improvement of their botanical com­position by direct sowing. In order io achieve this aim, various methods are applied: among others, sowing directly into sward (Laissus, 1984) and others. Success of sowing depends mainly on the efficiency of introduction of new grass species into the sward which is beeing degradated. That is why an attempt was made to estimate the possibility of use of some species of grasses for improvement of communities dominated by Poa pratensis on peat soils (Wizna Fen).

Herbage Dynamics And Plant-Animal Performance On Altered Northern Great Plains Rangelands, P O. Currie, D C. Adams, J D. Volesky

IGC Proceedings (1977-2023)

Mechanical, chemical, and seeding treatments have been used on rangeland to increase herbage production (Griffith et al., 1985). These treatments are generally applied to rangelands in a low serial stage of succession. Improving these rangelands is of major economic importance to livestock producers attempting lo increase the efficiency of their operations. Our study evaluated 5 range improvement treatments for improving herbage and ani­mal production efficiency

Herbage And Seed Yields Of Common Vetch (Vicia Sativa L.), M A. Jimenez, M.J L. Casterllon, A E. Cervantes, E F. Cervantes

IGC Proceedings (1977-2023)

Alfalfa is the main forage species used in the dairy farms of the Central Valley of Mexico. Low temperatures and solar radiation during winter have been associated to the lower yields of alfalfa pastures from late fall to the end of winter. Winter pastures as annual ryegrass, small grains and com­mon vetch can overcome the seasonal low yields of alfalfa (Victoria, 1981). Use of common vetch to provide high yields of herbage of good quality during winter has been increasing; however, availability of seed is limited. In addition, there is little publi­shed information on management of common vetch pastures for …

Initial Growth Of Herbages On The Seedbeds With Abundant Crushed Wood Fragments: A New Method Of Ploughless Pasture Establishment In Japan (Ii), S Suzuki, T Sugiura, H Kobayashi

IGC Proceedings (1977-2023)

The pasture established by the new ploughless method produces lower levels of herbages in the first year (Sugiura et al., 1987). It is supposed that crushed wood fragments (CWF) arc easily dried in the seedbeds (Sugiura et al., 1986 ; Suzuki et al., 1986). We investigated the effects of the CWF and the water supplying character of the soils on the initial growth of the herbages in the seedbeds.

The properties of this method are the stump-cutter (SC) and the bush-cutter (BC) which are new machines for establishing grassland. Owing to these two machines, it is possible to con­verse the natural environment and to reduce establishing costs of grassland. This report refers to a …

Grassland Improvement By Clover Direct Drilling, Z Hrazdira

IGC Proceedings (1977-2023)

Besides the production function, grasslands have got also exceptional significance for environmental conditions, such as retention and protection of resources of drinking water,- pre­vention of erosion and devastation of soil. Their non-pro­duction functions are especially irreplaceable on slope grasslands which dominate in our country. The renewal should be a most efficient intervention on the weedy grassland swards without good species. But that tra­ditional technology can not be employed in most cases on slopes, in inundated areas or in submountain and hill regions of our country.

Methodology To Determine Planting Time In King Grass (Pennisetum Sp.) Using Historical Climatic Indices, J R. Ayala, M Sistachs, R S. Herrera

IGC Proceedings (1977-2023)

The determination of planting time by field trials has various disadvantages. These trials should be repeated at least for 3 years comparing different months and the extension of the results is limited. The analysis of the climatic effects would allow a greater generalization with correlations between cli­matic and establishment indices. The season of the year in which the highest number of correlations with monthly histori­cal climatic values are fulfilled is required so as to determine planting time. The objective of the present methodology is to select planting time by using correlations between climatic and establishment indices and the monthly characterization …
