The Perils Of Automated Wrist-Cuff Devices And Dental Chairs In Opportunistic Blood Pressure Screening, Merrill F. Elias, Amanda L. Goodell, Adam Davey

Maine-Syracuse Longitudinal Papers

In our opinion, the automated arm-cuff method should be used where the goal is OBPS and the patient should be properly seated at a table with BP measurement conducted following the recommendations of the American Heart Association.

Human Errors In Automated Office Blood Pressure Measurement, Merrill F. Elias, Amanda L. Goodell

Maine-Syracuse Longitudinal Papers

In this review of the literature and commentary, we examine the literature on automated blood pressure (BP) measurements in the office and clinic. Our purpose is to revisit issues as to the pros and cons of automated BP measurement published in Hypertension in June 2020 and to identify areas needing additional research. Despite initial reservations about automated BP, it is here to stay. A number of experts suggest that human error will be reduced when we move from the more complex skills required by aneroid sphygmomanometer measurement to the fewer skills and steps required by automated BP measurement. Our review …

Leisure Activity For Dementia Prevention. More Work To Be Done., Victor W. Henderson, Merrill F. Elias

Maine-Syracuse Longitudinal Papers

Dementia prevention is a worldwide priority because of the aging population, devastating consequences for patients and families, and the drain on societal resources. In the absence of disease-modifying therapies, there is interest in lifestyle factors that might prevent or delay the onset of dementia. Chief among these is leisure activity, conceptualized as pursuits undertaken for relaxation or pleasure after completion of essential chores and occupational responsibilities. Leisure activity invokes the cornerstones of cognitive reserve: mental activity, physical activity, and social engagement.

Building Life-Cycle Carbon And Operational Energy Report, Duncan Cox, Alexandra Davis, Vamshe Gooje

General University of Maine Publications

The premise of this report is to surmise the embodied carbon impact and anticipated operational energy use of the 57,995 sf crosslaminated timber (CLT) and glulam addition to the Advanced Structures and Composites Center (ASCC) on the University of Maine campus. The project will contain open lab space for the world’s largest prototype polymer 3D printer, offices, and a presentation venue.

A life-cycle assessment is a methodology for quantifying environmental impacts at all stages of a building’s life cycle. This is a cradle-to-grave assessment of the building, beginning from raw material extraction and sourcing, to manufacturing, transportation, construction, energy use, …

Exploration Of The Relationship Between The Fractal Dimension Of Microcalcification Clusters And The Hurst Exponent Of Background Tissue Disruption In Mammograms, Betelhem Abay

Honors College

Breast cancer is one of the most frequent cancers among women worldwide and holds the second place in cancer-related death. Mammography is the most commonly used screening technique, however, the dense nature of some breasts makes the analysis of mammograms challenging for radiologists. The 2D Wavelet Transform Modulus Maxima (WTMM) is one mathematical approach that is used to for the analysis of mammograms. In 2014, a team from the CompuMAINE Lab characterized differences between benign microcalcification clusters (MC) from malignant MC by calculating their fractal dimension, D, with the aid of the 2D WTMM method. In a different implementation of …

Selectivity Of The Catalytic Hydrogenation Of Cinnamaldehyde Using A Polymer Cross-Linked Catalyst, Madeline Logan

Honors College

The transition from non-renewable fossil fuel chemical feedstocks to bio-renewable chemical feedstocks will be vital for the health of the environment. The current processing and use of fossil fuels produced by the petroleum industry release greenhouse gasses like carbon dioxide into the air causing heat to get trapped in the atmosphere. If greenhouse gas emissions continue at the rate they are now it is expected to cause polar ice caps to melt, ocean levels to rise, and climate all over the globe to change. By switching to bio-renewable feedstocks, the level of greenhouse gasses emitted would drastically decrease because processing …

Comparison Of Drying Methods Of Cellulose Nanofibrils Low Density Foams And Their Effects On Structural Properties, Lauren Ryan

Honors College

Cellulose nanofibrils (CNF) are a promising biomaterial made of cellulose, the most abundant biopolymer on the planet, and are produced in mass quantities by the Process Development Center at the University of Maine.One promising application of these materials are low-density foams, or aerogels, which are commonly prepared using lyophilization and solvent-exchange methods. Each of these methods rely on different physical and chemical processes to remove liquid from a given substrate and may impact the overall structure of a material in different ways. The purpose of this work was to determine if these drying techniques have any significant effect on the …

Using Cellulose Nanofibrils And Calcium Carbonate In Single-Use Utensils, Sierra Yost

Honors College

As humanity becomes aware of the environmental issues that come from plastics, substitutes for single-use plastic are needed. Straws, expanded polystyrene, and grocery bags especially have been placed under scrutiny, but there is a need to replace other single use plastics such as eating utensils and cup lids. In this thesis, the properties of cellulose nanofibrils and calcium carbonate mixtures are characterized to determine the feasibility of their use as a plastic replacement. Using cellulose nanofibrils poses two challenges: 1) it shrinks when dried causing difficulty in forming an object, and 2) it is produced in a 3 weight percent …

Adherence To A Mediterranean Diet Associated With Lower Blood Pressure In A Us Sample: Findings From The Maine- Syracuse Longitudinal Study, Fayeza S. Ahmed, Alexandra T. Wade, Benjamin A. Guenther, Karen J. Murphy, Merrill F. Elias

Maine-Syracuse Longitudinal Papers

Hypertension is a key modifiable risk factor for cardiovascular disease. The Mediterranean diet (MedDiet) may be associated with improvements in blood pressure. However, few studies have examined the association between MedDiet adherence and blood pressure in non-Mediterranean populations, and findings are mixed. We analyzed cross-sectional data (Wave 6) for 851 participants of the Maine-Syracuse Longitudinal Study. MedDiet adherence was calculated using food frequency questionnaire data and a literature-based MedDiet adherence score. Dependent variables included systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and mean arterial pressure (MAP). Separate linear robust regression analyses revealed significant associations between MedDiet …
