All Rsif Scholars' Publications

Over 90% of barite mining activities in Nigeria are carried out by artisanal and small-scale miners (ASMs), and up to 75% of these miners operate informally, without mining license and rights. Such mining activities endanger human lives through the uncontrolled release of toxic heavy metals and other pollutants which are major causes and consequences of severe health hazards in children and adults living close to the mining sites. This paper is in two parts. The first section assesses the extent of heavy metal contamination of Cd, Cu, Fe, Pb, Ba, and Zn in drinking water by the mine water and …

Esperanza Rising And Identity: Exploring Literature And Self In Upper Elementary School, Emma Fuller

Honors Program: Senior Projects (Public)

Upper elementary students benefit from exposure to windows and mirrors in literature. The term “mirrors” refers to when students can relate to characters and situations, and see their own lives valued in an academic context. Mirrors are important for representation in schools because it allows students to reflect on their own learning. “Windows” allow students to see a perspective into other people’s lives. They are important because they encourage reflection on different ideas and empathy among students. One of many literary works with strong “windows” and “mirrors” is Pam Munoz Ryan’s Esperanza Rising. In this Senior Project, I focused on …

Programmed To Protect And Serve: The Dawn Of Drones And Robots In Law Enforcement, Nanci K. Carr

Journal of Air Law and Commerce

No longer does the field of law enforcement rely solely on human cognition and capability as drones have become first responders, responding to emergency calls with a drone rather than a human officer. Drone technology can transform police work, just as it has package delivery and military strategy. These drone officers allow for higher law enforcement efficiency, safer communities, and even saved lives. However, they also raise civil liberty concerns given that the drones have the power to track vehicles and people without consent, and they can collect and store video records of everyday life, reducing expectations of privacy. This …

"The" Rule: Modernizing The Potent, But Overlooked, Rule Of Witness Sequestration, Daniel J. Capra, Liesa L. Richter

Faculty Articles

Starting with its illustration in the Apocrypha and continuing into the modern day both in courtrooms and in ubiquitous criminal procedurals, one evidence rule has proven so powerful that it has become known as "THE" Rule of Evidence. The rule of witness sequestrationdemands that multiple witnesses to the same events be examined separately from one another to prevent them from, consciously or subconsciously, tailoring their testimony to ensure that it remains consistent. Witness sequestration is conceptually simplistic and famously mighty. Yet, this bedrock protection against inaccurate trial testimony is imperiled by conflicting interpretations of Federal Rule of Evidence 615, the …

Thermophilic Campylobacter species of poultry origin have been associated with up to 80% of human campylobacteriosis cases. Layer chickens have received less attention as possible reservoirs of Campylobacter species. Initially, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of two archived Campylobacter isolates (Campylobacter jejuni strain 200605 and Campylobacter coli strain 200606) from layer chickens to five antimicrobials (ciprofloxacin, nalidixic acid, erythromycin, tetracycline, and gentamicin) were determined using broth microdilution while the presence of selected antimicrobial resistance genes was performed by polymerase chain reaction (PCR) using specific primers. Whole-genome sequencing (WGS) was performed by the Illumina HiSeq X …

Comparing Effectiveness, Cost- And Time-Efficiency Of Control Options For Xanthomonas Wilt Of Banana Under Rwandan Agro-Ecological Conditions, Guy Blomme, Petronille Dusingizimana, Jules Ntamwira, Elizabeth Kearsley, Svetlana Gaidashova, Anne Rietveld, Boudy Van Schagen, Walter Ocimati

All Rsif Scholars' Publications

Xanthomonas wilt of banana (XW) is a major disease affecting banana throughout East and Central Africa (ECA). Initial control was through complete diseased mat uprooting (CDMU), which had limited adoption due to high labour demands and cost. Further research demonstrated single dis- eased stem removal (SDSR) was an effective, less labour intensive and less costly alternative to CDMU. A comparative assessment of the two con- trol practices was needed to foster uptake by policy makers, especially in countries like Rwanda where SDSR had not been tested or scaled up. To test SDSR in Rwanda, a study was conducted in farmers’ …

Nanobodies: Their Potential For Applications In Biotechnology, Diagnosis And Antiviral Properties In Africa; Focus On Application In Agriculture, Faith Njeri Njeru, Paul Mbogo Kusolwab

All Rsif Scholars' Publications

Antibodies are key elements in routine immunological tests, having a long history in detection of plant pathogens due to their specificity, reliability and fast performance. Heavy chain-only antibodies (HCAbs), circulating in the blood of camels are IgG isotypes that lack the light (L) chains and the heavy (H) chain is depleted of the first constant domain (CH1). The HCAbs interact with the antigen by virtue of only one single variable domain, referred to as VHH or nanobody (Nb). Owing to their unique properties: nanometer scale size, robust structure, stable and soluble behaviour in aqueous solution, high affinity and specificity for …

Elucidation Of Multi-Origin Inula Helenium L. For Antimicrobial Activity And Heavy Metal Profiling As An Exemplar For The Use And Regulation Of Plants As Antibiotics., Ciara Ruth Kenny

Theses

An impending post-antibiotic era looms, thus new sources of therapeutic chemical entities are crucial to sustain effective antimicrobial chemotherapy worldwide. Plant natural products are a source of accessible, structurally diverse compounds that provide therapeutic potential. The pharmacological applications of plants in medicine can be guided by the attestation of traditional use or the application of this knowledge to uncover new leads in the drug discovery process. The range of modified in vitro methods commonly used to investigate preclinical antimicrobial efficacy of plant-derived natural products, and the associated limitations and challenges in the provision of new antimicrobial drugs from plants is …

First Record Of Blacknape Large-Eye Bream Gymnocranius Satoi (Perciformes: Lethrinidae) In The Philippines, Nicko Amor Flores, Jade Tifany Rey, Jeffrey T. Williams, Kent Carpenter, Mudjekeewis Santos

Biological Sciences Faculty Publications

The Philippines has been regarded as the center of the center of marine shorefish biodiversity, having the highest number of fish species per square area in the world. The blacknape large-eye bream, Gymnocranius satoi, has been reported to occur from Southern Japan, Taiwan to Northwestern Australia and to the Coral Sea, but has not previously been recorded from the Philippines. From 2011 – 2019, the National Fisheries Research and Development Institute (NFRDI) collaborated with the National Museum of Natural History of the Smithsonian Institution (NMNH/SI), USA, and the Old Dominion University (ODU), Virgina, USA, to inventory all commercial fish …

Microwaving Dreams? Why There Is No Point In Reheating The Hart-Dworkin Debate For International Law, Jason A. Beckett

Faculty Book Chapters

A critique of attempts to transpose Hart and Dworkin's legal theories to international law. I demonstrate why neither approach can provide insights into international law. Hart and Dworkin are institutional theorists, their methodologies are anchored by the need to justify the exercise of socially centralised violence. International law lacks both institutions and centralised violence, and the stabilising force these bring; it is radically indeterminate. Attempts to suppress this indeterminacy have resulted in international lawyers fragmenting into communities of practice, united by their eschatological faith in the international community. I challenge this faith.

The tourism sector constitutes significant importance for the Egyptian economy, with a contribution of 11.9% to the GDP and total employment of 2.49 million in 2018. The sector has different segments including both mass and niche tourism, where Egypt is heavily dependent on the former. Over the past 10 years, the sector was hammered by several internal and external intermittent hits, resulting in instability in the sector and fluctuations in its revenues that have consequently pulled down the foreign currency reserves. The current challenge of COVID-19 has introduced a new global norm that hurdled the mobility of mass tourist groups …

A Multi-Wavelength Study Of The Disk Winds And Their Role In The Agn Studies, Maryam Dehghanian

Theses and Dissertations--Physics and Astronomy

Active galactic nuclei (AGNs) are located at the centers of massive galaxies and are the most luminous objects in the universe. Each AGN embeds a super-massive black hole which produces outflows of gas, or winds. These winds are important because they provide a reasonable physical basis for the connections between the black hole and the properties of their host galaxy. While AGNs have been extensively studied, several fundamental questions about them are yet to be answered. These include the structure and dynamics of the central source and their winds, and questions regarding the evolution of these galaxies.
