Volume is an important attribute used in many forest management decisions. Data from 83 fixed-area plots located in central New Brunswick, Canada, are used to examine how different measures of stand-level diameter and height influence volume prediction using a stand-level variant of Honer's (1967) volume equation. When density was included in the models (Volume=f(Diameter,Height,Density)) choice of diameter measure was more important than choice of height measure. When density was not included (Volume=f(Diameter,Height)), the opposite was true. For models with density included, moment-based estimators of stand diameter and height performed better than all other measures. For models without density, largest tree …

Rates Of Diagenesis Of Tropical Insectivorous Bat Guano Accumulations: Implications For Potential Paleoenvironmental Reconstruction, Donald A. Mcfarlane, Joyce Lundberg
Rates Of Diagenesis Of Tropical Insectivorous Bat Guano Accumulations: Implications For Potential Paleoenvironmental Reconstruction, Donald A. Mcfarlane, Joyce Lundberg
International Journal of Speleology
Cave guano deposits are increasingly being recognized as valuable repositories of paleo-climatic and paleo-environmental information. However, that value is constrained by rates of guano decomposition, and these rates have not been previously well-studied. Here we show that field and laboratory studies of deep insectivorous bat guano sequences in the caves of Borneo demonstrate the extreme dependence of decomposition rate on guano water content. Under tropical conditions, moist guanos exhibit decomposition coefficients (k) values of ~ 0.01, implying the loss of most of the organic content on decadal timescales. Under similar temperatures but drier conditions, k values drop to …

Revolutionizing Denture Excellence: An Invigorating In-Vitro Exploration Of Organic Products In Prosthetic Rehabilitation, Nighila Ravindran, Sneha Joseph, Aswani Surya K
Annual Research Symposium
The denture base comes into contact with diverse substances in the oral cavity, acting as a reservoir for microorganisms like corynebacterium, streptococcus, lactobacillus, and candida. This colonization elevates the risk of complications such as denture stomatitis and candidiasis. Commercial denture cleaners have explored the use of natural ingredients, less commonly employed but offering various advantages. These ingredients aim to mitigate the potential issues associated with microbial colonization on denture surfaces, contributing to improved oral hygiene for denture wearers. The exploration of natural elements reflects a nuanced approach to denture care, considering both efficacy and less conventional alternatives.

Music Genre Classification Capabilities Of Enhanced Neural Network Architectures, Joshua Engelkes
Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal
With the increase of digital music audio uploads, applications that deal with music information have been widely requested by streaming platforms. Automatic music genre classification is an important function of music recommendation and music search applications. Since the music genre categorization criteria continually shift, data-driven methods such as neural networks have been proven especially useful to music information retrieval. An enhanced CNN architecture, the Bottom-up Broadcast Neural Network, uses mel-spectrograms to push music data through a network where important low-level information is preserved. An enhanced RNN architecture, the Independent Recurrent Neural Network for Music Genre Classification, takes advantage of the …

Assessment Of Emotional Intelligence Among Students In Dental College, Gowri Nandana S Final Year Student, Sudeep C. B Professor And Head Of The Department Of Public Health Dentistry
Assessment Of Emotional Intelligence Among Students In Dental College, Gowri Nandana S Final Year Student, Sudeep C. B Professor And Head Of The Department Of Public Health Dentistry
Annual Research Symposium
Over an extended period, the examination of intelligence predominantly centered on the adaptive deployment of cognitive abilities. In more recent times, scholars such as Gardner (1983) and Sternberg (1988) have proposed comprehensive frameworks for comprehending intelligence. Pioneering the concept of "emotional intelligence," Salovey and Mayer (1990) posited that emotional intelligence encompasses three distinct categories of adaptive capabilities: the evaluation and expression of emotions, the regulation of emotions, and the utilization of emotions in problem-solving. The objective is to evaluate emotional intelligence among dental students across various educational institutions.

Isolation And Culture Of Epichloё Sp. For Re-Infection Of Endophyte-Free Southeastern Wildrye (Elymus Glabriflorus), B. J. Haile, J. I. Morrison
IGC Proceedings (1977-2023)
Mutualistic relationships between endophytic fungi and grasses have shown to improve the hardiness of the host. This relationship is common in grasses, including native cool-season grasses that are important in both forage and grassland ecosystems. Elymus genus members, such as Canada wildrye (CAWR), commonly host the endophytic fungi, Epichloё, while southeastern wildrye (SEWR) may not. In this study, seed of ten Elymus accessions and seed and leaves from local SEWR were assessed for endophyte infection. Infection status was confirmed via seed squash and leaf peel techniques and assessed using microscopy. Seed of one SEWR and nine CAWR accessions were assessed …

Virtual Fencing Predictable For Cattle? A Simple Method To Test Whether And How Fast Cattle Can Learn The Association Between Acoustic Signal And Electric Pulse, D. Hamidi, M. Komainda, N. Grinnell, L. Wilms, F. Reisch, J. Horn, M. Hamidi, J. Isselstein
IGC Proceedings (1977-2023)
Virtual fencing (VF) offers promising future prospects for improved grazing management as it has the potential to simplify fencing. VF lines are easily drawn and shifted via GPS coordinates. A VF collar emits an acoustic signal when the animal approaches the VF line. The signal stops immediately when the animal turns around. If the animal continues to move towards the VF line, a short electric pulse is emitted. A teaching and an operating mode are provided by the VF collars. The animals automatically change mode when they respond correctly to 20 consecutive acoustic signals without receiving an electric pulse. A …

More Than A Fencing System? Testing The Validity Of Virtual Fencing Collars For Animal Monitoring On Pasture, D. Hamidi, M. Komainda, N. Grinnell, F. Reisch, J. Horn, M. Hamidi, I. Traulsen, J. Isselstein
IGC Proceedings (1977-2023)
High labour requirements for fencing and animal monitoring appear to be general obstacles for the wider use of pastureland for grazing livestock. Virtual fencing (VF) enables a less laborious pasture management. Fence lines can be easily drawn and moved using GPS data. The advantages of VF for reducing the labour inherent to controlled grazing management are obvious. Potential additional animal monitoring opportunities arising from such a VF system that uses real-time GPS data have not yet been studied. Lying is seen as an indicator for assessing comfort or restlessness of cattle. Therefore, we focus on lying behavior in this evaluation. …

An Assessment Of Young Cattle Behaviour And Welfare In A Virtual Fencing System, C. Holohan, A. Gordon, R. Palme, S. Buijs, F. Lively
IGC Proceedings (1977-2023)
Virtual fencing is a novel technology which uses a combination of audio and electrical stimuli to contain grazing livestock within a GPS boundary. There are however some concerns around the use of such a technology and its potential effects on the behaviour and welfare of animals. To investigate this, 64 dairy-origin calves were assigned to one of two treatments in a randomised complete block design, with 4 groups of 8 calves per treatment. The two treatments were virtual fencing (VF) and electric fencing (EF). The experimental period lasted 31 days in total, consisting of a 10 day training period and …

Scaled Datasets Through Leveraging Technology Better Represent Plant Communities Classified Within National Land Cover Database (Nlcd), D. M. Johnston, D. B. Murray, Y. Y. Tsang
IGC Proceedings (1977-2023)
Technological advances in remote sensing have allowed for access to and application of large- scale datasets of plant communities using cover classification and chlorophyll content measurement with the use of multispectral sensors and vegetation indices. The United States’ primary remote sensing platform Landsat Thematic Mapper is a series of satellites providing 30-meter resolution imagery of the Earth’s surface. Efforts have been made to best utilize Landsat derivative National Land Cover Database (NLCD) datasets and provide spatial resolution commensurate with the needs of plant ecologists and range managers. However, usage of 30-meter spatial resolution imagery and indices does not allow detection …

Heavy Grazing Significantly Reduced The Temporal Stability Of Aboveground Biomass, X. Ju, T. T. Shen, Q. Wu, G. D. Han
IGC Proceedings (1977-2023)
The stability of a plant community is the embodiment of the dynamic balance achieved by the interaction between populations in the form of competition or mutual benefit. Temporal stability refers to the ratio of the average value to the variance of the biomass of the population or community. For grassland ecosystems, the stability of the grassland plant community is the basis for its survival and functional performance, and is the key factor affecting its structure and function. In order to study the impact of grazing on the temporal stability of aboveground biomass of desert steppe, this study used a completely …

Migration And Colonization Characteristics Of Endophytic Tracer Rhizobia To The Reproductive Organs Of Alfalfa, W. J. Kang, S. L. Shi, Y. T. Zhang, L. Y. Chen
IGC Proceedings (1977-2023)
Legume seeds are the product of long-term natural selection and the co-evolution of rhizobia and seeds. They are more competitive than the native rhizobia in constructing symbiotic nitrogen-fixing systems with host plants. However, the paths and impact factors of rhizobia invasion and migration in plants, as well as colonization in seeds, are unclear. Here, alfalfa cultivars WL343HQ and Gannong 5, and three cyan fluorescent protein-tagged rhizobia (FTR), 3436f, 12531f and gn5f were used as materials. The effects of potassium dihydrogen phosphate (KH2PO4) and fulvic acid (FA) on the migration and colonization of FTR in the reproductive organs of field plants …
