- Abstract/Description
-
Construction workers are exposed to fine particulate inhalation hazards during stucco removal. The ultimate goal of this research is to test a new chemical-assisted method that will reduce workers’ exposures to safer levels. To that end, the minimum specimen size must be determined that will replicate this hazardous work environment. Samples of concrete stucco surfacing material (CSSM) of various sizes ranging from 1-in×1-in. to 8-in.×16-in. were applied to masonry blocks. These specimens...

The ultimate goal of this research is to test a new chemical-assisted method that will reduce workers’ exposures to safer levels. To that end, the minimum specimen size must be determined that will replicate this hazardous work environment. Samples of concrete stucco surfacing material (CSSM) of various sizes ranging from 1-in×1-in. to 8-in.×16-in. were applied to masonry blocks. These specimens were tested to determine the minimum size needed to produce 150-mg/m3 (one order of magnitude larger than the OSHA exposure limit of 15-mg/m3) of airborne particulate in a 1-m3 test chamber when removed with a chipping hammer. Testing results revealed that 5-in.× 5-in. specimen size yielded on average 180-mg/m3 of particulates.

- Abstract/Description
-
Pentraxin 3 (PTX3) has been demonstrated as a vital biomarker for chronic inflammatory diseases. Decreased plasma PTX3 has been observed in obese populations. However, no studies have examined the impact of obesity on PTX3 reactivity to exercise. Therefore, our study sought to investigate PTX3 plasma response to maximal exercise in obese and normal-weight subjects, and its relationship with insulin sensitivity. Twenty-one subjects (9 obese and 12 normal-weight) were recruited. Plasma PTX3,...
Show morePentraxin 3 (PTX3) has been demonstrated as a vital biomarker for chronic inflammatory diseases. Decreased plasma PTX3 has been observed in obese populations. However, no studies have examined the impact of obesity on PTX3 reactivity to exercise. Therefore, our study sought to investigate PTX3 plasma response to maximal exercise in obese and normal-weight subjects, and its relationship with insulin sensitivity. Twenty-one subjects (9 obese and 12 normal-weight) were recruited. Plasma PTX3, insulin, and glucose levels were measured before and following exercise. While our results showed lower resting PTX3 levels in obese subjects, exercise elicited similar elevations in PTX3 and insulin sensitivity in both groups. Furthermore, PTX3 area-under-curve (AUC) was correlated with glucose AUC, even when controlled for body mass index and fitness level. These findings suggest that glucose may potentially regulate PTX3 response to exercise. Further investigation is needed to verify the impact of substrate utilization on exercise-induced PTX3 elevation.

Show moreFlame is a computer worm that is being used for targeted cyber espionage in Middle Eastern countries. It is considered one of the most complex malware ever found. Flame can record audio, screenshots, keyboard activity and network traffic. It also has a kill switch to erase itself. Its program modules are encrypted. We are writing a misuse pattern to describe its architecture. A pattern is a solution to a recurrent problem in a given context. A pattern embodies the knowledge and experience of software developers and can be reused in new applications. A security pattern describes a mechanism or procedure to defend against an attack. A misuse pattern describes how a misuse is performed from the point of view of the attacker. It defines the environment where the attack is performed, countermeasures to stop it, and provides forensic information in order to trace the attack once it happens.

Show moreAn important authentication method is multi-factor authentication (MFA). Products such as Enterprise Office 365 are already using it, available for any user in Office 365 Midsize Business, Enterprise, Academic, and Nonprofit plans as well as the standalone versions of Exchange Online and SharePoint Online. The log-in verification feature is aimed at reducing users' vulnerability to online identity theft, phishing, and other scams by adding a second level of authentication to an account log-in. Twitter, Apple, PayPal, Google, Facebook, and other vendors already have implemented it. After correctly entering their username and password, users need to acknowledge a phone call, text message, or an app notification on their smartphone before they can gain access to their account. Two-factor authentication is the most common form of MFA and requires the use of two of the three authentication factors: Something only the user knows, something the user has, and something only the user is. In this work we will analyze some varieties, do UML models of their structure and dynamics, and compare MFA to other authentication approaches.

Such a pattern can inform IT managers, device manufacturers, or even device driver developers of the vulnerability, as well as detail methods or security patterns that can prevent an attack. A keyboard injection misuse attempts to infiltrate a system or network through a variety of techniques. Such a misuse impersonates a keyboard HID, which most systems inherently trust.

The remote input device is a gloved sensor fitted with flexing sensors that monitor an arthritic patient’s joint movement. The controller then sends the signal to be amplified to a normal full range of motion. That signal is sent to the robotic hand which plays the piano. Linear movement of the wrist is transferred with a sliding device. This project was a success and actually was able to assist people in remotely playing a scale on the piano.

Regulatory agencies need simple test for ARI to monitor environmental quality. This study is first to measure resistance in a consortium of bacteria, not pure cultures. Our rapid method – “In-the-zone” (ITZ) employs a) the size of zones of inhibition b) identity of bacteria in the zone c) number of resistant clones within zones of inhibition and d) type of antibiotic to compute ARI. Results can be obtained within 24 - 48 hrs with very little effort. This semester, we repeated the test and validated the weighting of various parameters. The ITZ assay yield consistent and reproducible data on zones of inhibition of bacteria community. The diameter of inhibition zones was the most important parameter distinguishing resistomes of varying ARI. Landfill, manured garden, and waste plant samples scored highest in antibiotic resistance index compared to beach sand.

Show moreAge-related neurodegenerative diseases impact society in an increasing rate. Oxidative damage to cellular molecules is considered the main cause of many neurological diseases such as, Alzheimer’s disease, Parkinson’s disease, etc. Understanding the mechanism and what cleans up oxidized molecules is vital in order to further explore therapeutic research for neurodegenerative diseases. RNA damage is potentially a major contributor to these diseases. However, compared to our knowledge about DNA, little is known about the mechanism that cells use to eliminate damaged RNA. Our objective in this study is to understand the role of proteins that specifically bind oxidized RNA. We will focus on one such protein TruD in Escherichia coli. By studying how TruD and its mutants help E. coli to survive oxidative stress, we hope to elucidate a mechanism by which cells fight against RNA oxidation, and to suggest disease-preventing mechanisms by the human TruD homologs on a molecular level.

Show moreTo fully understand the function of the elasmobranch electrosensory system it is necessary to examine electrosensory nerves extending from the ampullae of Lorenzini to the central nervous system. Studies detailing the composition of sensory axons are rare, but they have shown that ontogenetic and sexual dimorphism exists in the anterior lateral line nerve (ALLN) of numerous species. This study obtained a count of the number of axons comprising the ALLN in male vs. female and adult vs. juvenile yellow stingrays (Urobatis jamaicensis). We hypothesized that males have more axons than females, and that the number of axons is ontogenetically constant. We expect males to have 30% more axons in their ALLN, and that the number of axons is ontogenetically constant for both sexes. This study will provide unique data about the electrosensory nerves of Yellow stingrays that can be used in future studies to make comparisons between other species.

Conopressins are conopeptides that target vasopressin/oxytocin receptors in vascular smooth muscle cells that are found within blood vessels. The crustacean cardioactive peptide (CCAP) is a homologous peptide found in crustaceans and has been shown to behave as a cardioaccelerator in a homologous system. This study describes the effects of CCAP in Drosophila larvae. We find that CCAP has an inotropic effect by causing a change in the contraction of blood vessels. We further investigate the effects of another possibly cardioactive conopeptide, γ-conopressin-vil, in Drosophila larvae. Elucidating the effects of conopetides in Drosophila larvae may translate to cardioactive therapeutic uses in mammalian systems.

These habitat disturbances commonly favor invasive species such as the red fire ant (Solenopsis invicta). The red fire ant has been detected on aprons of gopher tortoise burrows at the FAU preserve and we would like to evaluate whether the distribution of red fire ants overlaps with that of the tortoises burrows. Ant distribution was accessed at the FAU preserve by running 10 random 100m transect lines and placing sardine baits at every 20m interval. Preliminary data suggests that red fire ants were abundant in 70% of the transects; however, we were unable to establish a direct correlation between the distribution of gopher tortoise burrows and that of red fire ants. The ants were tentatively identified to subfamilies and further identification will be performed.

ANOVA analyses revealed men and European Americans to consume significantly more alcohol than others. The age at which one began drinking significantly predicted numerous drinking behaviors: average number of drinks consumed, b=-.35, t(47)=-2.56, p < .05; largest number of drinks consumed per occasion, b=-.43, t(48)=-3.26, p < .01. Conversely, older age of one’s first binge drinking experience significantly predicted future frequent drinking behaviors.

Participants performed three cognitive computer tasks at both baseline (T1) and follow-up (T2) assessment. At T2 participants also filled out a drug usage questionnaire. This study stems from a larger longitudinal pilot study. Strong correlations were found for increased cigarette use: the number of drinking days reported, r (34) = .442, p =.007, as well as non-binge drinking days and marijuana use, r (34) =.465, p =.004. Cigarette smokers were more likely than not to partake in multiple drinking behaviors. Marijuana was found to be used more on days in which binge drinking did not occur alluding to a preference to smoke rather than drink excessively while smoking marijuana.
