The Impact Of Participation In 4-H Camp On The Connectedness To Nature Of Urban 4-H Members, Derek S. Landrum

LSU Master's Theses

Overnight summer camps are beneficial experiences that provide 4-H members from urbanized areas the chance to experience the outdoors and appreciate nature. Previous research shows that time in the outdoors can increase connection to nature. Furthermore, connection to nature is associated with adoption of pro‑environmental behavior, lowering of negative emotions, and positive general well-being. For this thesis, the researcher is interested in finding out if participation in 4-H summer camp has a significant effect on participant’s connection to nature as measured by the Children’s Environmental Perceptions Scale (CEPS) and the Inclusion of Nature in Self Scale (INS). Previous work has …

Productivity Of Wood Ducks, Black-Bellied Whistling-Ducks, And Hooded Mergansers Using Nest Boxes In Louisiana, Dylan L. Bakner

LSU Doctoral Dissertations

Resident female wood ducks (Aix sponsa) in the southeastern United States are managed through nest box programs, with the goal of enhancing local hunting opportunities. Historically, hooded mergansers (Lophodytes cucullatus) were the only other cavity-nesting waterfowl species in the southeastern United States known to use these nest boxes. However, the recent northward range expansion of black-bellied whistling-ducks (Dendrocygna autumnalis) has extended into the range of wood ducks and mergansers. All three species are brood parasites, potentially using one another as hosts for their parasitic eggs and impacting their reproductive output. My research evaluated the …

Yeast Crf1p: An Activator In Need Is An Activator Indeed, Sanjay Kumar

LSU Doctoral Dissertations

Ribosome biogenesis is an energetically costly process, and tight regulation is required for stoichiometric balance between components. This requires coordination of RNA polymerases I, II, and III. Lack of nutrients or the presence of stress leads to downregulation of ribosome biogenesis, a process for which mechanistic target of rapamycin complex I (mTORC1) is key. mTORC1 activity is communicated by means of specific transcription factors, and in yeast, which is a primary model system in which transcriptional coordination has been delineated, transcription factors involved in regulation of ribosomal protein genes include Fhl1p and its cofactors, Ifh1p and Crf1p. Ifh1p is an …

Ramadan Fasting Did Not Lessen Vegetable And Fruit Consumption, Sleep Duration, And Physical Activity On Adolescents In Universitas Al-Azhar Indonesia, Afradina Septiasari, Elma Alfiah, Andi Mukramin Yusuf, Amalina Ratih Puspa

Indonesian Journal of Public Health Nutrition (IJPHN)

Muslims do Ramadan fasting for around 12 hours (between dawn and sunset). Apart from changing meal times, Ramadan fasting also has the potential to change sleep duration due to sahoor (before the dawn) activities that must be done. The ideal amount and frequency of vegetables and fruit consumption in the national guideline were illustrated by the three main meals a day. The different conditions occurred when doing Ramadan fasting, which was predicted to have less vegetable and fruit consumption than the normal days, especially Muslim adolescents. This research analyzed the difference between the consumption of vegetables and fruit, sleep duration, …

Introduction—Approximately 1% of the world’s population is impacted by epilepsy, a chronic neurological disorder characterized by seizures. One-third of epileptic patients are resistant to AEDs, or have medically refractory epilepsy (MRE). One non-invasive treatment that exists for MRE includes the ketogenic diet, a high-fat, low-carbohydrate diet. Despite the KD’s success in seizure attenuation, it has a few risks and its mechanisms remain poorly understood. The KD has been shown to improve metabolism and mitochondrial function in epileptic phenotypes. Potassium channels have implications in epileptic conditions as they have dual roles as metabolic sensors and control neuronal excitation.

Inter-organelle contact and communication between mitochondria and sarco/endoplasmic reticulum (SR/ER) maintain cellular homeostasis and are profoundly disturbed during tissue ischemia. We tested the hypothesis that the formin Diaphanous-1 (DIAPH1), which regulates actin dynamics, signal transduction and metabolic functions, contributes to these processes. We demonstrate that DIAPH1 interacts directly with Mitofusin-2 (MFN2) to shorten mitochondria-SR/ER distance, thereby enhancing mitochondria-ER contact in cells including cardiomyocytes, endothelial cells and macrophages. Solution structure studies affirm the interaction between the Diaphanous Inhibitory Domain and the cytosolic GTPase domain of MFN2. In male rodent and human cardiomyocytes, DIAPH1-MFN2 interaction regulates mitochondrial turnover, mitophagy, and oxidative stress. …

A Framework For Transparency In Precision Livestock Farming, Kevin C. Elliott, Ian Werkheiser

Philosophy Faculty Publications

Simple Summary

The emergence of precision livestock farming (PLF) raises important issues for many different social groups, including farmers, consumers, regulators, and the food industry. This paper explores how those who develop PLF systems can communicate more effectively with different groups about the technologies that they are creating. We suggest that developers reflect on four issues: (1) the different kinds of information that various groups might want to know; (2) the audiences that might care about these different kinds of information; (3) the major difficulties involved in providing the information; and (4) potential strategies for overcoming those difficulties.

High-Performance Technique For Estimating The Unknown Parameters Of Photovoltaic Cells And Modules Based On Improved Spider Wasp Optimizer, Safaa Saber, Sara Salem

Sustainable Machine Intelligence Journal

To better estimate the unknown parameters of the double-diode model, a new optimization technique based on the newly proposed spider wasp optimizer (SWO) is introduced in this study. The performance of SWO was further enhanced by integrating it with a local search strategy to propose a new improved variant called ISWO. This improved variant has a high ability to extensively exploit the solutions surrounding the best-so-far solution in an effort to speed up convergence and produce better results in fewer function evaluations. Using the RTC France solar cell and three PV modules (STM6-40/36, STP6-120/36, and Kyocera KC200GT), ISWO and SWO …

Instrumental Pub Decors: Non-Sounding Functional Instruments, Nuria Bonet

The bar El Nou Trull in La Garriga (Catalonia) is decorated with an agricultural theme – decorative objects found here include two olive oil presses, baskets and bottles. The decoration also features instruments, presumably intended to convey a rural feeling. The choice of instruments is peculiar, from a balalaika and drums to a cymbal and a metronome (!). I could not help wondering: what function do these decorative instruments play in the bar?We may assume that instruments are defined by their sound and that their function is determined by their sounding, the musicians that have owned them, and the performance …

Integrated Pest Management And Behavior Of Stored Grain Beetles, Ethan Doherty

LSU Doctoral Dissertations

The lesser grain borer, Rhyzopertha dominica, and the rice weevil, Sitophilus oryzae, are two of the most destructive pests of stored rice. Their management has relied heavily upon fumigant insecticides. However, amid growing concerns that fumigant-resistant pests are becoming widespread, there is an urgent need for diversified management techniques and integrated pest management. Here, we explored management techniques and the behavior of these beetles. Host plant resistance toward both beetles was evaluated for 13 varieties of rice. We found large differences among varieties for both beetles in all resistance measures. We found that while nutritional components of a …
