Touchless Thermal Respiratory Monitor
Get PDFAn abnormal respiratory rate and changes in respiratory rate can give an early indication of physiological disorders such as a stroke or heart failure. Also, many drugs prescribed for pain or sedation carry the risk for respiratory depression. Medical devices used to track breathing today often require the use of wires and sensors that can create obvious restrictions in the patient’s motion, ability to maneuver, or even sleep. The long-term objective of this research project is to build a system that can monitor breathing without coming into contact with a patient. The goal of the current project is to optimize the functionality of the sensor and prove functionality by testing on human subjects. The Touchless Thermal Respiratory Monitor was built using a thermal sensor, 3-D printed parts, and a laser. The thermal sensor was programmed to read temperature, and in this project, the location yielding the greatest temperature differential between the air that has been exhaled by the patient and the room temperature will be found. The laser will allow for proper alignment of the thermal sensor to this location. The temperature difference will be monitored and plotted in MATLAB in order to track the respiratory rate. Irregular signals or a lack of signal would indicate that the patient is having breathing problems, or that the patient has moved out of the sensors path
The Intertwined Successional Development of the Lamb Gut Microbiota And Immune System (Poster)
Get PDFGastrointestinal tract (GIT) microbes play critical roles in host nutrition, health and immunological development. For adult ruminants, GIT-dwelling microbes provide ~70% of daily energy requirements. The GIT also houses 70 % of the animal’s immune system in the form of the Gut-associated Lymphatic Tissue (GALT), which houses 80% of all plasma cells and depends on microbial stimulation for maturation. Because nutrition and disease are two major factors in the economic sustainability of livestock production, our group set out to characterize the successional development of GIT microbiota and immune activity. Blood and GIT samples were collected from lambs immediately at birth through one-year of age, and from the dam’s vagina, mouth, and rectum at parturition. Blood samples were profiled for serum titers of IgM, IgA and IgG, while microbiota were profiled in GIT samples by 16S rRNA gene sequencing. Lamb GIT microbiota initially resembled the dam’s vaginal microbiota but following exposure to the dam, became rapidly more similar to the dam’s teat. GIT samples eventually formed stable climax communities similar to the dams around 180 days of age. This corresponded to the peak serum titers for each immunoglobin, which, aside from a peak in IgG at birth (likely colostral transfer), had gradually increased prior to this time. Immunoglobins peaked and then return to a sub peak level between 180 and 365 days. These results indicate dam vaginal microbiota have a short-lived impact on the neonatal microbiota, with the GIT microbiota going through a dynamic successional development to 180 d when immune function appears to peak
Determining the Place of AQP-3B in the WNT/CA2+ Noncanonical Pathway (Poster)
Get PDFDuring Xenopus laevis gastrulation, convergent extension is required for the mesoderm to extend into the embryo and shape the embryonic body plan. Recent results from our lab suggest that the inhibition of aqp-3b prevents convergent extension of the mesoderm and that aqp-3b acts through noncanonical Wnt signaling. Wnt signaling is a key signal pathway for embryo and tissue development. There are two types of Wnt signaling pathways, the canonical and the noncanonical pathways. There are three separate branches to noncanonical Wnt signaling. Our lab has shown that aqp-3b acts through the noncanonical Wnt/Ca2+ pathway and that it acts upstream of the cytoplasmic Wnt signaling pathway member Disheveled. The Frizzled7 membrane receptor is part of the noncanonical Wnt/Ca2+ pathway and also acts upstream of Disheveled. I will test, whether in this signaling cascade, aqp-3b acts upstream or downstream of Frizzled 7. Thus, I will test whether Frizzled 7 activates aqp-3b, if aqp-3b activates Frizzled 7, or if aqp-3b is bypassed and Frizzled 7 activates disheveled. When Frizzled 7 is active, GFP-labeled protein kinase C (PKC-GFP) relocates from the cytoplasm to the plasma membrane. Thus, I will inject either PKC-GFP alone, PKC-GFP + fz7, or PKC-GFP + fz7 +aqp-3bMO (to inhibit aqp3b) into two-cell Xenopus embryos and examine under a fluorescence microscope whether the PKC is bound to the membrane (Wnt signaling active) or remains in the cytoplasm (no Wnt signaling). With this procedure the place of aqp-3b within the Wnt/Ca2+ pathway will be determined
The Academic Library’s Role in Student Retention
Get PDFStudent retention is critical to job security, but most importantly, we who work in academeare entrusted with our students’ dreams. While there are many factors that enter into students’ eventual graduation from college, the library can help by understanding some of the basics of the literature of student retention and then by creating spaces, collections, and personnel who are responsive to student needs. This session at PNLA’s 2015 conference outlined research about student retention, summarized some of the reasons that it matters, and offered up some strategies that the author’s library is using to be part of an overall campus effort to improve retention

Service Design: Toward a Holistic Assessment of the Library
Get PDFService design is a holistic method for assessing service delivery that requires serviceproviders to take on a user-centered perspective, that focuses on how each piece makesup the whole and the cumulative impact on the user’s experience. Service design alsonecessitates that during the assessment we think about the library as a set of serviceswithin a highly integrated system. When we, as service providers, look at the librarythrough this lens, we begin to see the library through the user’s eyes. This article will definelibrary services in the context of service design and discuss the service design projectbeing conducted at the Reed College Library before sharing our own personal insightsinto the process and its benefits
Beyond the Region: Cuban Libraries, a Humbling Experience
Get PDFVintage automobiles from 1960 and older cruise the roads with engines that have been massaged over the years to keep them running. The weathered buildings and worn stairways were built to last, but show years of exposure to the elements and multitudes of foot traffic. I stepped into the past on this trip and I am now envisioning Cuba’s future in light of the recent US and Cuban talks. Access to much needed materials will truly change Cuba. As librarians and educators we can impact this transition. At present Cuban libraries have very limited resources, yet Cuba has one of the highest literacy rates in the world. How do they manage it

Get PDFCreativity is in so much of what we do as information professionals!Programming and services to youth come to mind quickly, but Ifind the most amazing creativity appears when we have to solve thelarger challenges facing libraries today. Issues such as meeting theneeds of our patrons and exploring ways to remain relevant in today’sworld require creativity and out-of-the-box thinking from all ofus
