Hadhramout University Journal of Natural & Applied Sciences

A new sugar sensor based on metal oxide is presented here. The variation on the sensor resistance is studied against different glucose and fructose concentrations (1 - 360 mg/dl). The study is done for three different resistive films (i) pristine palladium oxide (PdOx); (ii) tin oxide (SnO2) and (iii) palladium doped tin oxide (Pd-SnO2). The chemical reactions of glucose and fructose with surface species were studied. Pd-SnO2 films show an excellent and reliable response to glucose and fructose solution in comparison with the bare films (PdOx and SnO2). Sensor performance was checked for the blood of normal (120 mg/d) and …

Effect Of Feed Amount And Composition On Blaine And Residue In Cement Mill, Ahmed Mubarak Alsobaai

Hadhramout University Journal of Natural & Applied Sciences

This study investigates the effect of the amount and composition of cement ball mill feed on Blaine fineness and cement residue. The collected data were obtained using a ball mill for grinding clinker and additive materials (pozzolana and gypsum) at different amounts and composition of feed. The fineness of cement was measured as a specific surface by the air permeability method (Blaine Method) and the residue was calculated as cumulated residue on a 45 microns sieve. It was found that the cement residue increased with an increase in the amount and composition of feed while the Blaine fineness decreased. The …

Groundwater extraction from this basin has already exceeded the safe yield of the aquifer, a sharp drop in the water table, and …

Activity Performance And Stability Of Functionalized Sba -15 Mesoporous Silica For Lipase Immobilization, Ahmed Mubarak Alsobaai Dr

Hadhramout University Journal of Natural & Applied Sciences

SBA -15 Mesoporous Silica was synthesized and functionalized with aminopropyl-, phenyl- and chloropropyl- using post-synthesis method. The esterification of citronellol with lauric acid in batch mode at 37 ◦C was used to measure the performance of the immobilized enzymes. Characterization of the supports revealed the satisfactory development of mesoporosity with uniform internal channels distribution. Pure SBA-15 showed the typical hexagonal pore and straight channels while the functionalized SBA-15 with triethoxysilane caused pore size to decrease and the distortion of internal channels occurred to subsequently improved the degree of immobilization. The best support among the four was the 3-aminotriethoxysilane functionalized SBA-15 …

The Role Of African Proverbs In Advancing Information Systems Research, Tiko Iyamu

The African Journal of Information Systems

Despite the richness of African proverbs, they have been muted in information systems (IS) research. This explicitly contributes to the lag in developing information systems and technology solutions for African people by African researchers in African terms. It is on this basis that two related objectives were formulated: (1) to examine the role which African proverbs can play in further advancing IS research, and (2) to understand how the concept can be employed to indigenize IS research. Qualitative data were collected from different sources, and the dimension of social change from structuration theory was employed to examine the role African …

Government Workspace Digitalization And Socioeconomic Development Outcomes In Ghana, Winfred Ofoe Larkotey, John Effah, Richard Boateng

The African Journal of Information Systems

The study sought to understand how the structurational environment shapes socioeconomic outcomes of government workspace digitalization in Ghana based on a qualitative, interpretive case study and the structurational model of technology as a theoretical lens. The findings show how the availability of electronic transactions law, government borrowing, and extendable system design can positively influence socioeconomic outcomes of government workspace digitalization. However, use of multiple system development environments, bureaucracy, a within-country digital divide, and a persistent physical signature and letterhead culture can negatively influence the socioeconomic development goals of government workspace digitalization.

Integrating Social Justice Theory Into Engineering Practice, Letitia Thomas

Baldy Center Blog

Engineering education has historically been limited in developing students’ awareness of social justice issues, even though research tells us that students who are underrepresented (by class, race, gender, etc.) can be empowered and retained when participating in social justice projects related to engineering (Lucena & Leydens, 2015; Mejia, 2017). My goal is to integrate social justice theory into engineering practice, to empower UB students to make a lasting, collective impact in their community. I want students to study and learn social justice themes while becoming more socially and critically conscious about their own influence, as creators of technology.

The Efficacy Of Tocilizumab As A Therapeutic Treatment For Sars-Cov-2 Infections: An Integrative Literature Review, Amanda Vancene Peterson

Nursing Masters Papers

The novel coronavirus SARS-CoV-2 and resulting COVID-19 infection has spread from a cluster of unidentified pneumonia cases in Wuhan, China, into an ongoing global health crisis. The strain on the healthcare systems and loss of human life has made finding ways to treat severe COVID-19 infections of the utmost importance. Mortality from COVID-19 has been shown to result from an overwhelming inflammatory response similar to the cytokine release syndrome seen in certain autoimmune reactions (Tleyjeh et al., 2020). It also can be seen after chimeric antigen receptor T-cell (CAR-T) therapy for certain cancers. It is hypothesized that treatments targeting the …

Calvin ENGR 333 students partnered with Habitat for Humanity to tackle the issue of carbon emissions when designing their homes. Habitat for Humanity for Kent County is endeavoring to design homes that reduce energy consumption, energy expenditures, and carbon emissions. They are embarking upon a “carbon footprint build” that will minimize energy consumption and carbon emissions, both during construction and across the lifetime of their new Habitat for Humanity homes. This semester, the senior mechanical engineering …

Enhancing Therapeutic Approaches For Melanoma Patients Targeting Epigenetic Modifiers., Maria Gracia-Hernandez, Zuleima Munoz, Alejandro Villagra

Biochemistry and Molecular Medicine Faculty Publications

Melanoma is the least common but deadliest type of skin cancer. Melanomagenesis is driven by a series of mutations and epigenetic alterations in oncogenes and tumor suppressor genes that allow melanomas to grow, evolve, and metastasize. Epigenetic alterations can also lead to immune evasion and development of resistance to therapies. Although the standard of care for melanoma patients includes surgery, targeted therapies, and immune checkpoint blockade, other therapeutic approaches like radiation therapy, chemotherapy, and immune cell-based therapies are used for patients with advanced disease or unresponsive to the conventional first-line therapies. Targeted therapies such as the use of BRAF and …

Clustering Methods For The Efficient Voltage Regulation In Smart Grids, Brook Abegaz

Engineering Science Faculty Publications

In this paper, clustering methods are presented to enhance the stability of automatic voltage regulators using the efficient adjustment of their respective gains. The results show that implementations of some of the clustering algorithms provide better reliability and stability for the feedback-based voltage regulators as compared to the other methods, namely, a model predictive controller (MPC), a gaussian mixture model (GMM), a self-organizing mapping (SOM) and hierarchical clustering (HC) methods. Specifically, the K-Means clustering approach (KM) provided superior stability but a slower rise time of the output voltage of the voltage regulators as compared to the other methods. Furthermore, coordination …

Injectable Decellularized Nucleus Pulposus Tissue Exhibits Neuroinhibitory Properties, Logan M. Piening, David J. Lillyman, Fei San Lee, Alvaro Moreno Lozano, Jeremy R. Miles, Rebecca A. Wachs

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: Chronic low back pain (LBP) is a leading cause of disability, but treatments for LBP are limited. Degeneration of the intervertebral disc due to loss of neuroinhibitory sulfated glycosaminoglycans (sGAGs) allows nerves from dorsal root ganglia to grow into the core of the disc. Treatment with a decellularized tissue hydrogel that contains sGAGs may inhibit nerve growth and prevent discassociated LBP.

Methods: A protocol to decellularize porcine nucleus pulposus (NP) was adapted from previous methods. DNA, sGAG, α-gal antigen, and collagen content were analyzed before and after decellularization. The decellularized tissue was then enzymatically modified to be …

Development And Evaluation Of An Improved Microbial Inactivation Model For Analyzing Continuous Flow Uv-Led Air Treatment Systems, Cole Holtom Thatcher

Theses and Dissertations

This thesis discusses the development of an improved microbial inactivation model for analyzing continuous flow UV-LED air treatment systems and use of the model to evaluate the impact of several treatment system design parameters on inactivation. Model development includes three submodels: a radiation submodel, a fluid flow submodel, and an inactivation kinetics submodel. Radiation modeling defines the UV irradiance throughout the system. Fluid flow modeling provides the residence times that microbes spend exposed to the UV irradiation while passing through the system. Inactivation modeling combines irradiance and residence times with inactivation kinetics to calculate species-specific inactivation in a treatment system. …

Evaluating And Enhancing Iron Removal Via Filterable Iron Precipitates Formation During Coal-Waste Bioleaching, Prasenjit Podder, Zongliang Zhang, Rick Q. Honaker, Michael L. Free, Prashant K. Sarswat

Mining Engineering Faculty Publications

Iron removal via jarosite precipitate formation is a commonly used technique in various hydrometallurgical processes. Excess iron removal often becomes essential to an overall metal recovery circuit. This is particularly important to processes involving iron-bearing minerals. A technique, which involved the use of pyrite to generate acid for leaching, for iron removal is critical to enabling the process. Iron removal using CaO or similar reagents is expensive and often results in lost product. In the present study, various compounds that facilitate jarosite formation, namely Na₂SO₄, NH₄OH, KCl, and KOH, were utilized and their effect …

The Distributed Trust Model Applied To The Energy Grid Of Things, Narmada Sonali Fernando

Dissertations and Theses

Electric power system operators can manage distribution system utilization and usage by coordinating end customer usage of distributed energy resources. The end customers in this regard are Service Provisioning Customers, who provide their energy resources to a Grid Service Provider, which in turn dispatches large aggregations of distributed energy resources to provide reliable service to the power system. The security of this system relies upon information protection mechanisms, as described in IEEE 2030.5. However, in addition to preventive security measures, a monitoring function is required to ensure trustworthiness.

Trust models are a method to detect and respond to both expected …

11 Pressing Research Questions On How Light Pollution Affects Biodiversity, Franz Holker, Janine Bolliger, Thomas W. Davies, Simone Giavi, Andreas Jechow, Gregor Kalinkat, Travis Longcore, Kamiel Spoelstra, Svenja Tidau, Marcel E. Visser, Eva Knopp

School of Biological and Marine Sciences

Artificial light at night (ALAN) is closely associated with modern societies and is rapidly increasing worldwide. A dynamically growing body of literature shows that ALAN poses a serious threat to all levels of biodiversity—from genes to ecosystems. Many “unknowns” remain to be addressed however, before we fully understand the impact of ALAN on biodiversity and can design effective mitigation measures. Here, we distilled the findings of a workshop on the effects of ALAN on biodiversity at the first World Biodiversity Forum in Davos attended by several major research groups in the field from across the globe. We argue that 11 …

Fungal Community And Functional Responses To Soil Warming Are Greater Than For Soil Nitrogen Enrichment, Mark A. Anthony, Melissa A. Knorr, Jessica A. M. Moore, M. Simpson, Serita D. Frey

Faculty Publications

Soil fungi are key regulators of forest carbon cycling and their responses to global change have effects that ripple throughout ecosystems. Global changes are expected to push many fungi beyond their environmental niches, but there are relatively few studies involving multiple, simultaneous global change factors. Here, we studied soil fungal diversity, community composition, co-occurrence patterns, and decomposition gene responses to 10 years of soil warming and nitrogen addition, alone and in combination. We specifically examined whether there were fungal community characteristics that could explain changes in soil carbon storage and organic matter chemistry in chronically warmed and fertilized soil. We …

Identifying Sinorhizobium Meliloti Genes That Determine Fitness Outcomes, Alexander B. Benedict

Theses and Dissertations

The remarkable metabolic capacity of the soil-dwelling bacterium Sinorhizobium meliloti is encoded on its three circular replicons: the chromosome and two large megaplasmids, pSymA and pSymB. Despite making up 45% of the genome, the pSymA and pSymB megaplasmids can be cured from S. meliloti. This unique attribute provides an opportunity to study the essentiality of chromosomal genes in the presence or absence of nearly half the genome. By interrogating chromosomal genes via massively parallel transposon insertion sequencing (Tn-seq) in the presence and absence of pSymA and pSymB, we identified 307 genes as being essential for viability regardless of the genomic …

Fibrin Prestress Due To Platelet Aggregation And Contraction Increases Clot Stiffness, Suyog J. Pathare, Wilson Eng, Sang Joon J. Lee, Anand K. Ramasubramanian

Faculty Research, Scholarly, and Creative Activity

Efficient hemorrhagic control is attained through the formation of strong and stable blood clots at the site of injury. Although it is known that platelet-driven contraction can dramatically influence clot stiffness, the underlying mechanisms by which platelets assist fibrin in resisting external loads are not understood. In this study, we delineate the contribution of platelet-fibrin interactions to clot tensile mechanics using a combination of new mechanical measurements, image analysis, and structural mechanics simulation. Based on uniaxial tensile test data using custom-made microtensometer and fluorescence microscopy of platelet aggregation and platelet-fibrin interactions, we show that integrin-mediated platelet aggregation and actomyosin-driven platelet …
