Ecology Of Periphyton In A Subtropical River Floodplain, Kamela De Gallardo

LSU Doctoral Dissertations

The Atchafalaya River Basin (ARB) in southcentral Louisiana, USA, is a large and biologically diverse floodplain surrounding the Atchafalaya River (AR), which is the largest distributary of the Mississippi River, receiving 30% of the combined daily discharge of the Mississippi and Red Rivers. Annual flooding facilitates exchange between the AR and its floodplain and is thought to give rise to the high productivity of the river-floodplain system. Primary production within the aquatic ARB is driven by periphytic algae, phytoplankton, and aquatic macrophytes, however, very little is known about periphytic algal assemblages in floodplain systems. In this study, artificial substrates were …

IGC Proceedings (1977-2023)

Natural and semi-natural grasslands represent an attractive forage source for cows in organic dairy farming. Throughout the grazing season, however, diverse factors such as climatic conditions, botanical composition, as well as grazing and herd management, can influence growth and nutritive value of forage on grasslands. We aimed at investigating the influence of seasonality and grazing management in forage growth and nutritional quality in seven commercial organic dairy cattle farms during the grazing season 2019 in South Germany. Therefore, forty exclusion cages (1 m²) were installed on pastures, which were under three different grazing systems: rotational, short-grass, and continuous …

IGC Proceedings (1977-2023)

Alfalfa is a very important forage for livestock feeding. In particular, due to the high crude protein content, it is widely used as a dairy cattle feeds. However, the cultivation of alfalfa is quite limited and main source is imported hay in Korea. There are many reasons, but most importantly, low productivity due to lack of boron in the soil. This experiment was conducted to expand domestic production and use of alfalfa. Alfalfa was sown in the fall of 2018 at 30 kg/ha seeding rate. Alfalfa was harvested four times (3 May, 2 July, 11 September and 13 October) in …

Economic Injury Level For Bermudagrass Stem Maggot (Diptera: Muscidae) In Bermudagrass Forage Production In Texas, V. Corriher-Olson, A. Knutson, F. Mitchell

IGC Proceedings (1977-2023)

The bermudagrass stem maggot, Atherigona reversura Villeneuve, was first reported damaging bermudagrass Cynodon dactylon (L.) Pers grown for forage in 2010 in the southeastern US. Damage results from individual larvae feeding internally on the vascular tissue just above the terminal node of the grass stem. Damage slows plant growth and reduces forage accumulation. To address the need for economic guidelines to manage this new pest, the relationship between the percent of stems damaged by bermudagrass stem maggot and forage yield was measured in commercial bermudagrass hay fields in northcentral Texas during 2016 and 2017. The slope of the linear regression, …

Encounters Between The Elderly And Law Enforcement

Contemporary Southern Psychology

The elderly population is growing dramatically throughout the world. Out of this growth comes an increase in the number of encounters between the aged and law enforcement. These encounters occur because of a variety of factors including mental illnesses and addictions. Furthermore, older adults may be victims as evidenced in different forms of abuse such as physical, emotional, or financial abuse. Sadly, some documentation exists that older adults are committing more crimes. Multiple reasons have been postulated for these crimes including poverty, jealousy, and boredom. All of these different situations with the aged have created an increase in the number …

Surveillance Of Sars-Cov-2 Rna In Open-Water Sewage Canals Contaminated With Untreated Wastewater In Resource-Constrained Regions, Paramita Basu, Sandeepan Choudhury, Varsha Shridhar, Poorva Huilgol, Samrat Roychoudhury, Indranil Nandi, Angela Chaudhuri, Arindam Mitra

Touro College of Pharmacy (New York) Publications and Research

Sewage-based surveillance for COVID-19 has been described in multiple countries and multiple settings. However, nearly all are based on testing sewage treatment plant inflows and outflows using structured sewage networks and treatment systems. Many resource-limited countries worldwide have open canals, lakes and other such waste-contaminated water bodies that act as a means of sewage effluent discharge. These could serve as hyperlocal testing points for detecting COVID-19 incidence using the effluents from nearby communities. However, a sensitive, robust and economical method of SARS-CoV-2 RNA detection from open waste contaminated water bodies in resource-constrained regions is currently lacking. A protocol employed in …

The savannas of the Kenya-Tanzania borderland cover >100,000 km² and is one of the most important regions globally for biodiversity conservation, particularly large mammals. The region also supports >1 million pastoralists and their livestock. In these systems, resources for both large mammals and pastoralists are highly variable in space and time and thus require connected landscapes. However, ongoing fragmentation of (semi-)natural vegetation by smallholder fencing and expansion of agriculture threatens this social-ecological system. Spatial data on fences and agricultural expansion are localized and dispersed among data owners and databases. Here, we synthesized data from several research groups and conservation …

Monolayer Graphene Radiation Sensor With Backend Rf Ring Oscillator Transducer, Mohamed W. Tawfik, Abdelhameed Sharaf, Mohamed Serry

Faculty Journal Articles

This paper proposes a new graphene gamma- and beta-radiation sensor with a backend RF ring oscillator transducer employed to convert the change in the graphene resistivity due to ionizing irradiation into a frequency output. The sensor consists of a CVD monolayer of graphene grown on a copper substrate, with an RF ring oscillator readout circuit in which the percentage change in frequency is captured versus the change in radiation dose. The novel integration of the RF oscillator transducer with the graphene monolayer results in high average sensitivity to gamma irradiation up to 3.82 kΩ/kGy, which corresponds to a percentage change …
