Little Effect Of Species Richness And Vegetation Composition On Herbage Production And Quality In A Permanent Temperate Grassland, Johannes Isselstein, Tatiana From, Ute Petersen, Nicole Wrage-Mönnig

IGC Proceedings (1977-2023)

Phytodiversity of grasslands has been shown to support production and other ecosystem services (e.g.Weigel et al. 2009, Tilman et al. 2012). However, in many of these studies, species richness was controlled by sowing and weeding and it was questionable to what extent the findings would also be applicable to permanent 'real world' grasslands where the species number is dependent on site and management conditions. In addition there is uncertainty about the effect of diversity on the herbage value for ruminants (Wrage et al. 2011). In a new approach to biodiversity experiments, we combined experimental and observational measures …

Yak Rearing On High Altitude Pastures Of Northeastern Himalaya Of India: Their Utilization Strategies And Rejuvenation, Vijay Paul, Sanjit Maiti, G. Krishnan, D. Medhi, S. M. Deb

IGC Proceedings (1977-2023)

Yak rearing on alpine pastures is the main occupation of the highland pastoral nomads (Brokpa and Dokpas) of north-east (NE) India. These pastoral nomads living in the remote mountains solely rely on high altitude pastures for their nutritional and livelihood security because of virtual existence of agricultural activities in this area. They rear yaks under transhumance and utilize various pastures while migrating from low land winter pastures to high altitude alpine pastures during summer. Therefore, the temperate and alpine pastures are the major feed resources for the yaks. The indiscriminate use of pastures and impending climate change results …

Use Of Native Grassland In Small-Scale Dairy Systems In The Highlands Of Central Mexico. A Case Study, P. A. Sainz-Sanchez, Carloss Manuel Arriaga-Jordan, D. Heredia Nava, C. G. Martinez-Garcia, F. Vicente, L. R. Garcia-Winder, A. Martinez-Fernandez

IGC Proceedings (1977-2023)

Small-scale dairy systems in Mexico comprise 78% of specialized dairy farms and provide 37% of national production. They are small farms with herds 3-35 cows plus replacements, and rely on family labour (Posadas-Domínguez et al., 2014).

In the highlands, many farms have native grasslands, grazed during the rainy season, and supplemented with other feeds as maize straw, maize grain and maize ears. Native grasslands have not been studied in this context. This is a case study on the use of native grassland in a small-scale dairy farm. The objective was to determine how native grasslands are integrated in feeding …

Designing A Smart Internet Of Things Solution For Point Of Use Water Filtration Management System In Residential, Commercial And Public Settings, Tristan Lim, Hwee-Pink Tan, Chin Sin Ong, Rahul Belani, Siddhant S. K. Agrawal

Research Collection School Of Computing and Information Systems

The use of water filtration Point-of-Use (POU) systems are extensive, ranging from water dispensers in public estates, to household POU water systems. Manufacturers typically recommend filtration cartridges to be changed (i) after their useful life, or (ii) when the water flow volume have exceeded certain capacity, whichever is earlier. However, filtration mechanisms are typically not changed with sufficient regularity. Overused filters can result in negative health effects, over and above the deterioration and loss of filtration benefits of the POU water system. Presently most existing water purification systems do not have smart connected Internet of Things (IoT) means of informing …

Andersson, Mirasol F. Pampolino, Ibrahim Mohammed, James Mutegi, Alpha Y. Kamara, Bernard Vanlauwe, Peter Q. Craufurd

All Peer-Reviewed Publications

In sub-Saharan Africa, there is considerable spatial and temporal variability in relations between nutrient application and crop yield, due to varying inherent soil nutrients supply, soil moisture, crop management and germplasm. This variability affects fertilizer use efficiency and crop productivity. Therefore, development of decision systems that support formulation and delivery of site-specific fertilizer recommendations is important for increased crop yield and environmental protection. Nutrient Expert (NE) is a computer-based decision support system, which enables extension advisers to generate field- or area-specific fertilizer recommendations based on yield response to fertilizer and nutrient use efficiency. We calibrated NE for major maize agroecological …

Comparative Physiology Of Honey Bees (Apis Mellifera L.) Exposed To Chlorantraniliprole, Jennifer Williams

Department of Entomology: Dissertations, Theses, and Student Research

One outstanding threat to the honey bee, Apis mellifera L., is the unintended exposure of these pollinators to agricultural pesticides. Anthranilic diamides, such as chlorantraniliprole, work in target pests through activation of the ryanodine receptor causing rapid feeding cessation, lethargy, paralysis, and eventual death. Chlorantraniliprole exhibits low acute toxicity to honey bees but relatively little information exists regarding effects of chlorantraniliprole exposure beyond mortality. The acute toxicity and metabolic detoxification enzyme activities following oral exposure were determined in the honey bee and the model crop pest, the fall armyworm (Spodoptera frugiperda, J.E. Smith). Additionally, chlorantraniliprole effects on honey bee …

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Declining the quantity and quality of freshwater resources in many parts of the world, including Midwestern USA, especially in the light of rapidly growing world’s population and changing climate, imposes significant and, in some cases imminent, challenges for producers, policy- and decision-makers to produce more yield with less water and other inputs, particularly in water scarcity regions.

There is not comprehensive previous research has quantified and evaluated coupled impacts of irrigation rates and nitrogen timing management strategies and their interactions on maize (Zea mays L.) productivity and its various attributed efficiency index metrics under different irrigation methods under the …

Alarm Forecasting In Natural Gas Pipelines, Colin Quinn

Master's Theses (2009 -)

This thesis examines alarm forecasting methods for a natural gas production pipeline to assure the efficient transportation of high-quality natural gas. Natural gas production companies use pipelines to transport natural gas from the extraction well to a distribution point. Forecasting natural gas pipeline pressure alarms helps control room operators maintain a functioning pipeline and avoid costly down time. As gas enters the pipeline and travels to the distribution point, it is expected that the gas meets certain specifications set in place by either state law or the customer receiving the gas. If the gas meets these standards and is accepted …

Investigating The Role Of Iron-Sulfur Signaling In Yeast Transcriptional Regulation, Malini Gupta

Theses and Dissertations

As an essential cofactor in a myriad of cellular processes, uptake and mobilization of iron must be tightly controlled. Iron homeostasis in fungi involves balancing iron uptake and storage with iron utilization to achieve adequate, non-toxic levels of this essential nutrient. Extensive work in the non-pathogenic yeasts Saccharomyces cerevisiae and Schizosaccharomyces pombe have uncovered unique iron regulation networks for each organism that control iron metabolism via distinct molecular mechanisms. The activities of all fungal iron-sensing transcription factors characterized to date are regulated via iron-sulfur cluster signaling.

In Saccharomyces cerevisiae, expression of iron uptake, utilization and storage genes is primarily regulated …

A decision support system (DSS) is a technology that takes minimal effort to learn and can assist in decision-making processes. This design science research builds and evaluates an IT artifact, a decision-support system, in an attempt to solve the problems facing school counselors. To develop this system, four design principles (system usefulness, interface quality, information …

Soil Biotic And Abiotic Conditions Negate Invasive Species Performance In Native Habitat, Pushpa Soti, Matthew Purcell, Krish Jayachandran

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Background: Most studies on plant invasion consider the enemy release hypothesis when analyzing native habitats. However, the lower performance of invasive species in the native habitats can be the result of unfavorable soil conditions in the native habitats. While soil biotic and abiotic factors have a potential to restrict the growth of invasive species in their native habitats, our understanding of belowground environment of invasive species in their native habitats is very limited. In this study, we analyzed soil characteristics associated with an exotic invasive plant, Old World Climbing Fern (Lygodium microphyllum), in its native habitat in Australia and the …

Activated Carbon Nanofibers From Renewable (Lignin) And Waste Resources (Recycled Pet) And Their Adsorption Capacity Of Refractory Sulfur Compounds From Fossil Fuels, Efstratios Svinterikos

Dissertations

Dementia is a condition in which higher mental functions are disrupted. It currently affects an estimated 57 million people throughout the world. Dementia diagnosis is difficult since neither anatomical indicator nor functional testing are currently sufficiently sensitive or specific. There remains a long list of outstanding issues that must be addressed. First, multimodal diagnosis has yet to be introduced into the early stages of dementia screening. Second, there is no accurate instrument for predicting the progression of pre-dementia. Third, non-invasive testing cannot be used to provide differential diagnoses. By creating ML models of normal and accelerated brain aging, we intend …

How Emergent Social Patterns In Allogrooming Combat Parasitic Infections, Shelby N. Wilson, Suzanne S. Sindi, Heather Z. Brooks, Maryann E. Hohn, Candice R. Price, Ami E. Radunskaya, Nakeya D. Williams, Nina H. Fefferman

Mathematics Sciences: Faculty Publications

Members of social groups risk infection through contact with those in their social network. Evidence that social organization may protect populations from pathogens in certain circumstances prompts the question as to how social organization affects the spread of ectoparasites. The same grooming behaviors that establish social bonds also play a role in the progression of ectoparasitic outbreaks. In this paper, we model the interactions between social organization and allogrooming efficiency to consider how ectoparasitic threats may have shaped the evolution of social behaviors. To better understand the impacts of social grooming on organizational structure, we consider several dynamic models of …

Strategies To Ameliorate Pasture Production For Livestock In High Altitude Regions, M. M. Roy

The high altitude regions in India exhibit a diverse climate, topography, vegetation, ecology and land use pattern. The annual average rainfall varies from 80 mm in Ladakh to over 200 cm in some parts of Himachal Pradesh and Uttar Pradesh. The vegetation varies from the scrub in the lower hills to arctic in the Greater Himalaya (GJK 2004). In this region, Ladakh is a unique land form encompassing distinct physical features, ecology, environment, ethnicity, agricultural systems and livestock rearing practices. This region experiences a very hostile climate and winter temperature may go as low as -30⁰ C. Summer temperature …

Local Use And Knowledge Validation Of Fodder Trees And Shrubs Resources Browsed By Livestock In Manipur (India), R. Joseph Koireng, Ansarul Haq, Kh. Priya Devi

IGC Proceedings (1977-2023)

North Eastern states of India particularly in Manipur livestock rearing were being considered as one of the important homestead activities in the farm household. In the rural household economy, livestock is considered as an inseparable component in the whole farm business, as the production of milk and meat as well as manure, draught and transportation depends on it. It provides nutritional security to farm family and stabilizes farm income too.

As a major source of animal feeds in Manipur, fodder trees and shrubs are highly valued by farmers. They have deep root systems enabling the extraction of water and nutrients …

Pasture Management For Sustainable Forage Production, Pijush Kanti Mukherjee, Putan Singh, S. S. Singh

IGC Proceedings (1977-2023)

In the livestock management grazing was the major feed resources in the past and even today a significant portion of livestock is being sustained on grazing resources from pastures and other grazing lands like forest, fallow lands, cultivable waste lands etc.

During the last few decades ever increasing livestock population has created enormous grazing pressure on pasture resources leading to deterioration and destruction of pastures. This has led to the urgent need of improvement of pastures as well as judicious implementation of grazing management practices. There has been certain constraints on pasture development which include fragmentation and degradation of …

Production And Quality Assessment Of Pasture Crop In Red Lateritic Wasteland Of Central Chhattisgarh, Mahendra Nath Naugraiya, G. S. Tomar

IGC Proceedings (1977-2023)

The livestock constitutes a very important component in rural economy, as in agriculture. Our country largely depends on livestock for manure and power. The availability of fodder is short from the requirement and an estimate of several agencies, there is more than 300 per cent gap between availability and requirement (Anon, 1980). Most of the livestock depend either partially or completely on natural and developed pastoral system, but the existing practices of utilization of range lands, grasslands and forest areas natural resources and increasing land degradation. In the improved pastoral system in wastelands, the carrying capacity of grass-legumes pastoral field …

The Microbiota-Gut-Brain Axis Heart Shunt Part I: The French Paradox, Heart Disease And The Microbiota, M. Obrenovich, B. Siddiqui, B. Mccloskey, Prakash Reddy

Chemistry Faculty Research & Creative Works

It has been well established that a vegetarian and polyphenol-rich diet, including fruits, vegetables, teas, juices, wine, indigestible fiber and whole grains, provide health-promoting phytochemicals and phytonutrients that are beneficial for the heart and brain. What is not well-characterized is the affect these foods have when co-metabolized within our dynamic gut and its colonizing flora. The concept of a heart shunt within the microbiota-gut-brain axis underscores the close association between brain and heart health and the so-called "French paradox" offers clues for understanding neurodegenerative and cerebrovascular diseases. Moreover, oxidation-redox reactions and redox properties of so-called brain and heart-protective foods are …

Effects Of Alternate Furrow Irrigation On The Forage Quality Of Alfalfa (Medicago Sativa), Xiao Yu, Zhengang Guo, Tingting Jia, Yuying Shen

IGC Proceedings (1977-2023)

Alfalfa (Medicago sativa) is widely used to establish pasture to sustain animal production because of its high nutritional quality for livestock (Bouton, 2012). Therefore improving quality of alfalfa pasture is the main goal for establishing pasture throughout the world. Irrigation is an important approach for achieving high qualities of alfalfa pasture, however, the scarcity of water threatens the sustainability of world alfalfa production, requiring us to force on using water more efficiently (Liu and Guo, 2013). Alternate furrow irrigation has been proved as a water-saving technique to promote fruit quality of tomatoes and grapevines and the seed quality …

The Impact Of Surface Coal Mining On The Pre- And Post-Mining Agricultural Potential Of The Grassland Biome Of Southern Africa, Wayne F. Truter, T. Bredell, J. Olivier, D. Van Heerden, P. Mosebi

IGC Proceedings (1977-2023)

Surface mining of coal is widespread in the grassland areas of the Mpumalanga Province in South Africa, and is the main cause of many environmental impacts in this agriculturally important region. To ensure healthy and productive vegetation after the reclamation process, disturbed soils need to be ameliorated and re-vegetated with locally adapted grass species to protect, preserve and improve soils for future agricultural use. To date, soil compaction is regarded as one of the main factors that cause severe restrictions in the effective rooting depth of plants, and the level of compaction is strongly influenced by altered soil water contents, …
