Some Remarks Concerning The Theory Of Nutrition And Biology Of Grass Stands, A Korab
Some Remarks Concerning The Theory Of Nutrition And Biology Of Grass Stands, A Korab
IGC Proceedings (1977-2023)
The growth rate and yielding capacity of grasses, expressed as kg crude protein/ha per unit of time, are dependent upon the plants' capacity to take up and utilize nitrogen. This character is specific in individual grass species and has been found to be more or less hereditarily determined and relatively coincident in different sites. These assumptions and interrelations have been utilized for determining the yield indices to express not only the relative yielding capacity of major cultivated grasses but also their requirements in terms of effective nitrogen nutrition. The principle of determining effective doses of nitrogen using the index method …

The Intensification Of Grass Production Through Nitrogen Fertilization, And The Nitrate Problem, Klau Ebert, Henrich Koriath, Gunter Rinno
IGC Proceedings (1977-2023)
Two-year pot and five-year field tests with increasing nitrogen doses revealed an increase in the nitrate content of forage grasses. In the pot tests the content of 0.25 % N03-N in the dry matter, which is safe in animal nutrition, had by far been exceeded. In the field tests the· nitrate content increased more slowly for the average of the tests and did not reach this limit when giving 140 to 240 kg N/ha. In single cases this value had, however, already been reached when giving 100 kg N/ha. By selecting grass species with a lesser tendency to nitrate accumulation, …

Forage And Feedstuff Analysis With Infrared Reflectance Spectro/Computer System1, J S. Shenk, K H. Norris, R F. Barnes, G W. Fissel
IGC Proceedings (1977-2023)
An infrared reflectance spectro/computer system (IRSCS) has been established at The Pennsylvania State University to evaluate the nutritional quality of forage and feedstuffs. Studies with alfalfa forage clearly show that the reflectance spectral curve of the forage is a composite curve consisting of various chemical constituents in the forage such as water, protein and cellulose. Chemical constituents are not measured directly by IRSCS but calibration prediction equations are developed from samples with known chemical constituents and animal response data. After this is completed, forage samples can be analyzed for multiple chemical constituents and animal responses in less than 2 minutes. …

Cancer is characterized by dysregulated metabolic signaling pathways, leading to uncontrolled cellular proliferation. Current cancer treatments, which involve surgery, radiotherapy, and chemotherapy, still cause adverse systemic toxicities. Accordingly, one possible effort that can be undertaken is to explore safe anticancer substances from protein sources such as peptides. Bioactive peptides can be isolated by hydrolyzing cowpea (Vigna unguiculata L. Walp) protein with trypsin. The objectives of this study were to isolate and fractionate bioactive peptides from cowpea, to determine the anticancer activity of peptide fractions, to identify active peptide fractions as anticancer agents using Liquid Chromatography High Resolution Mass Spectrometry …

Determinants Of Home Composting Behavior In Supporting Sustainable Agriculture Among Smallholder Farmers: A Case Study In The Thai Nguyen Province Of Vietnam, Bac Ho Van, Hien Vu Thi, Xinh Ho Luong
Journal of Environmental Science and Sustainable Development
Home composting is a practical and sustainable approach for the management of organic waste generated in the home and agricultural production that contributes to both organic waste management and soil fertility enhancement. In the northern mountainous regions of Vietnam, smallholder farmers face limited adoption of sustainable waste management practices due to behavioral constraints, limited technical knowledge, and resource constraints affecting agricultural productivity. This study applies and extends the Theory of Planned Behavior (TPB) by integrating behavioral and contextual determinants to examine home composting adoption among smallholder farmers in rural Vietnam. Principal Component Analysis (PCA) was used to reduce and structure …

Harmful Algal Blooms: Risks For Food In Utah, Jose Brandao, Sarah Erwin, Stephanie Vaughn, Clare Entwistle
All Current Publications
Harmful algal blooms (HABs) are a problem because they can produce toxins that make water unsafe for people, animals, and the environment. In recent years, HABs have emerged as a growing concern in freshwater systems throughout Utah, including irrigation canals, reservoirs, and livestock ponds. HABs in freshwater are caused by cyanobacteria, also called blue-green algae. These microorganisms can release dangerous toxins that can harm swimmers, pets, and the food supply. Unlike foodborne pathogens, these toxins cannot be removed by boiling, cooking, or washing the food. Therefore, regular monitoring is essential to detect HABs early and reduce exposure risks. This fact …

The Evaluation Of Relationships Between Ecological Factors And Production On Permanent Grassland, Vladimir Krajovic
The Evaluation Of Relationships Between Ecological Factors And Production On Permanent Grassland, Vladimir Krajovic
IGC Proceedings (1977-2023)
On 42 sites in 10 districts of the Carpathian region of the CSSR, relationships were examined between grassland production and regional, climatic (precipitation, temperature, solar radiation), and soil conditions (soil type, pH, S, 'r, V, C0., nutrients, and clay fraction). To this, five variants of fertilization were used (0; PK; 120 kg N/ha + PK, 240 kg N/ha + PK; 480 kg N/ha + PK). None of the natural ecofactors is generally characteristic enough for determining an optimal production. But the nutrition and the utilization of grass stands are important under each condition. Therefore, a system of differentiated grassland management …

IGC Proceedings (1977-2023)
Savannas subjected to seasonal flooding occupy· vast areas of the Tropics. Above-ground biomass values for Venezuelan flooded savannas are high and related to the longer availability of water. C3 plants colonized the waterlogged unit and showed the highest productivity and nutritive value. This natural system permits a prolonged grazing season. These first results show the great potential for animal production of this ecosystem, stressing the need for coordinated research efforts in order to gain a better understanding of it.
Influence Of Plant Nutrition And Method Of Utilization On The Accumulation And Decomposition Of Root Matter In Meadow Soils, Yan Liyv, Rikhard Toomre
Influence Of Plant Nutrition And Method Of Utilization On The Accumulation And Decomposition Of Root Matter In Meadow Soils, Yan Liyv, Rikhard Toomre
IGC Proceedings (1977-2023)
Root matter formation of forage plants depends primarily on soil fertility. In fertile soils and under intensive fertilization less root matter is formed than in soils of low fertility. The decomposition of root matter as influenced by microbiological processes was found to be more intensive under grazing than under mowing. The application of high rates of nitrogen fertilizer (more than 200 kg N/ha) over longer periods is likely to cause undesirable changes in the relationship between forage plants and soil microorganisms, this resulting in yield decline and in lower efficiency of the fertilizers applied.

Mab-Dqa: Addressing Query Aspect Importance In Document Question Answering With Multi-Armed Bandits, Yixin Xiang, Yunshan Ma, Xiaoyu Du, Yibing Chen, Yanxin Zhang, Jinhui Tang
Research Collection School Of Computing and Information Systems
Document Question Answering (DQA) involves generating answers from a document based on a user’s query, representing a key task in document understanding. This task requires interpreting visual layouts, which has prompted recent studies to adopt multimodal Retrieval-Augmented Generation (RAG) that processes page images for answer generation. However, in multimodal RAG, visual DQA struggles to utilize a large number of images effectively, as the retrieval stage often retains only a few candidate pages (e.g., Top-4), causing informative but less visually salient content to be overlooked in favor of common yet low-information pages. To address this issue, we propose a Multi-Armed Bandit–based …
Towards Audio-Driven Photorealistic Avatars For Teleconsultation: A Development And Evaluation Framework Under Constrained Bandwidth Environments, Fnu Himanshu
Graduate Theses and Dissertations
Telehealth can improve access to healthcare services, especially for patients in rural and underserved areas. Many telehealth services use video communication to provide real-time interaction and a visible connection between patients and healthcare providers. However, video communication requires continuous transmission of audio and video data. When network conditions are limited or unreliable, audio and video interruptions can reduce communication quality. This thesis explores an audio-driven photorealistic avatar as a possible visual communication layer for teleconsultation without requiring continuous webcam video transmission. It develops two connected frameworks: the Audio-Driven Photorealistic Avatar Communication Framework and the Evaluation Framework. The Audio-Driven Photorealistic Avatar …

(R2155) Mathematical Insights Into Cancer Cells Growth Stability And Chaos, Pardeep Kumar, Kashish Agarwal, Tripti Anand, Sarita Jha
Applications and Applied Mathematics: An International Journal (AAM)
In this research paper, we examined a recently proposed three-dimensional dynamical model of cancer cell growth that explicitly couples the populations of tumour cells, healthy host cells, and immune cells (Pardeep et al.). We aim to elucidate the model’s novel biological features relative to classical tumour–immune interaction models and to characterize its dynamical regimes. This model is governed by nonlinear differential equations featuring a quadratic tumour proliferation term and bilinear coupling terms for tumour–immune and tumour–host interactions. Then, we performed the rigorous analysis by solving the fixed-point equations and from the Jacobian matrices at the resulting equilibria to identify the …

Peptide And Peptide Bioconjugate Based Drug Development For The Treatment Of Metabolic Diseases, Nancy Cham
Dissertations - ALL
The Doyle group has coined the term ‘corrination’ to describe the conjugate modification of a peptide, protein, small molecule, or radionuclide with a corrin ring-containing molecule such as cobalamin, also known as vitamin B12 (B12), or cobinamides. By exploiting the innate chemico-physical properties of corrin ring-containing compounds, both in general and specifically via the innate dietary B12 uptake pathway in mammals, corrination has been explored for drug development and targeted/localized delivery of probes and therapeutics. Most recently, it is in the field of peptide-based therapeutics that corrination is generating significant interest, no doubt driven in part by the recent successes …
The Soil Crisis In Modern Food Systems: Rethinking Agricultural Land Use, Antonia Moure Richard
The Soil Crisis In Modern Food Systems: Rethinking Agricultural Land Use, Antonia Moure Richard
Journal of Food Law & Policy
Feeding a larger world while preserving the resource that makes agriculture possible—soil—poses a governance problem. By 2050, food systems must support 9.8 billion people even as prevailing practices continue to degrade soils that are non-renewable on human timescales. Technological fixes (e.g., vertical farming, hydroponics) may complement production, but they cannot substitute for soil at scale. The question that follows is simple: are current uses of soil compatible with the future needs of food systems? This article argues that without a shift in governance, short-run productivity gains are achieved by drawing down the soil asset, thereby undermining long-run food security and …
