The Effect of Antioxidant Addition on Lightfastness of Color Ink Jet Printing

Fluorescent office lighting has been shown to fade ink jet colors. Fading of ink jet dyes is a problem when the shelf life of documents is important. For effective, low cost ink jet printing, the color quality of the printed paper must be maintained for a duration of time. Research in hot melt adhesives has shown a reduction of color loss associated with the use of antioxidants. During this thesis, a coating formulation was tested with and without an antioxidant present. The antioxidants tested were alpha tocopherol I vitamin E, and sodium thiosulfate. The addition rate was varied at 2.65 % and 5.17 % to determine which addition rate was required to produce the best color fastness. Coated paper samples were printed with a color test pattern utilizing the primary colors: red, yellow, blue and black .. The paper samples, printed with the test pattern, were analyzed with the brightimeter to determine their initial color values (L, a, b) and brightness. The samples were aged using an accelerated aging device, the fade-ometer, to test the ability of the antioxidants to resist fading under fluorescence. It has been determined that the duration of 12 hours of 500 W/m2 is equivalent to one month of sunlight in Michigan in the month of June. The fade-ometer times were chosen to be 12, 24 and 36 hours of exposure representative of 1, 2 and 3 months of normal exposure. The L, a, b values of the samples were measured after each aging period. To determine the ability of the antioxidant to reduce color loss, all brightimeter values of each antioxidant coating were compared against all brightimeter values of the non-antioxidant coating. Both the basesheet and the coated sheets, after aging, were tested for brightness, and color difference (L, a, and b ). The results were compared to determine the surface effects of the coating on the substrate during time. Also, the results were compared to determine which antioxidant level minimizes color loss. The importance of this project was to determine the extent of color loss that is prevented by the use of antioxidants. Color ink jet printing must have the ability to resist color loss for a duration of time. Color fastness of the paper is important and should be maintained for a duration of time. Improved color fastness was shown to exist in paper samples coated with a low level of antioxidant. Both antioxidants, vitamin E and sodium thiosulfate, decreased the color loss associated with accelerated aging conditions in the fade-ometer

Not All the Organelles of Living Cells Are Equal! Or Are They? Engaging Students in Deep Learning and Conceptual Change

The cell is the fundamental basis for understanding biology much like the atom is the fundamental basis for understanding physics. Understanding biology requires the understanding of the fundamental functions performed by components within each cell. These components, or organelles, responsible for both maintenance and functioning of the cell comprise to form a dynamically stable ecosystem.  The secret of achieving this noble and desirable efficiency rely on the structural and functional variations of the organelles within the cell; they each carry out specific jobs within the cell resulting in a smooth, running process that would be the envy of any industrial manager. In this role-playing learning activity, we aim to engage students in deep learning that leads to cognitive and conceptual change by forcing them to be and to actively act as those organelles within the cell.  It is centered on the idea that a number of organelles within the eukaryotic cells are strongly “protesting” the “privilege” that mitochondria and chloroplasts have within the living cells (both in single and multi-cellular organisms).  They are protesting the structural and functional privileges that other organelles lack, but the mitochondria and chloroplasts have. Students will have to understand an explore the reasons for the differences among all the organelles and how they differ in importance and function, especially in regards to interactions between organelles within each cell and how it contributes to the life of the cell as a whole..  After all, as it has been stated by NGS (2007) “a human cell reveals our inner architecture” (p. 40).

Has the Time Come to Start a Dialogue About the Role of Nutrition and Our Inner Microbiomes In Education? Teacher and Faculty Perspectives

The purpose of this study is to determine if educational professionals at the high school and college levels believe that their students should be required to complete a Health and Nutrition and/or a Microbiology course for graduation. The study used both a descriptive survey and a questionnaire as data collection instruments. The study population was comprised of 655 teachers and instructors from high schools, colleges and universities across the U.S.A.   Quantitative analysis was conducted using descriptive statistics. Qualitative analysis of open ended responses was organized into multiple themes. While all the participants strongly agreed that our nation (U.S.A.) is facing critical challenges in overcoming the new trends in obesity, diabetes, infectious diseases and other related epidemics, as well as on the role of education in solving the matters, they differ on what to do and how to prepare the current and future generations. At the college level, while over half of all the participants (61.22%) preferred to see Microbiology as a part of the graduation requirement from college, only 41.22% of the same participants felt comfortable in making Nutrition a part of the graduation requirement.  At the high school level, while 42.59% of all the participants saw no problem in including Nutrition as a part of the graduation requirement from high school, only 10.53% of the same participants felt comfortable including Microbiology as a graduation requirement from high school.  More detailed outcomes are presented in this paper. However, more participating college instructors compared to high school teachers did not think either of the topics should be mandated for graduation from high school or college; the only exception would be if these two fields of study were part of their selected academic program. Instead, this group of participants suggested making changes to existing course design and content (such as the required “health” or Biology classes), which would offer valuable additions to the existing curriculum and prepare students in health and nutrition. Finally, almost all of the participants provided various reasons and justifications for their perspectives on the matter.  The study also shows a significant role for administrators and academic leaders in this requirement process (decision making process for the curricula). Recommendations based on the findings are provided and discussed below. Keywords: General education, Nutrition, Microbiology, Human Microbiomes, Obesity, Diabetes, Illness prevention, Infectious diseases, Education, burden of disease, educational reform

Occurrence of medical co-morbidity in mild cognitive impairment: implications for generalisation of MCI research

Background: diagnosis of mild cognitive impairment (MCI) typically excludes individuals with medical co-morbidity. Interest in MCI screening raises the questions of what are the best criteria to identify a representative sample and what factors are associated with MCI progression to dementia

Diverse tick-borne microorganisms identified in free-living ungulates in Slovakia

Background: Free-living ungulates are hosts of ixodid ticks and reservoirs of tick-borne microorganisms in central Europe and many regions around the world. Tissue samples and engorged ticks were obtained from roe deer, red deer, fallow deer, mouflon, and wild boar hunted in deciduous forests of south-western Slovakia. DNA isolated from these samples was screened for the presence of tick-borne microorganisms by PCR-based methods. Results: Ticks were found to infest all examined ungulate species. The principal infesting tick was Ixodes ricinus, identified on 90.4% of wildlife, and included all developmental stages. Larvae and nymphs of Haemaphysalis concinna were feeding on 9.6% of wildlife. Two specimens of Dermacentor reticulatus were also identified. Ungulates were positive for A. phagocytophilum and Theileria spp. Anaplasma phagocytophilum was found to infect 96.1% of cervids, 88.9% of mouflon, and 28.2% of wild boar, whereas Theileria spp. was detected only in cervids (94.6%). Importantly, a high rate of cervids (89%) showed mixed infections with both these microorganisms. In addition to A. phagocytophilum and Theileria spp., Rickettsia helvetica, R. monacensis, unidentified Rickettsia sp., Coxiella burnetii, "Candidatus Neoehrlichia mikurensis", Borrelia burgdorferi (s.l.) and Babesia venatorum were identified in engorged I. ricinus. Furthermore, A. phagocytophilum, Babesia spp. and Theileria spp. were detected in engorged H. concinna. Analysis of 16S rRNA and groEL gene sequences revealed the presence of five and two A. phagocytophilum variants, respectively, among which sequences identified in wild boar showed identity to the sequence of the causative agent of human granulocytic anaplasmosis (HGA). Phylogenetic analysis of Theileria 18S rRNA gene sequences amplified from cervids and engorged I. ricinus ticks segregated jointly with sequences of T. capreoli isolates into a moderately supported monophyletic clade. Conclusions: The findings indicate that free-living ungulates are reservoirs for A. phagocytophilum and Theileria spp. and engorged ixodid ticks attached to ungulates are good sentinels for the presence of agents of public and veterinary concern. Further analyses of the A. phagocytophilum genetic variants and Theileria species and their associations with vector ticks and free-living ungulates are required.Fil: Kazimírová, Mária.

Color Categorization Independent of Color Naming

Color is continuous, yet we group colors into discrete categories associated with color names (e.g., yellow, blue). Color categorization is a case in point in the debate on how language shapes human cognition. Evidence suggests that color categorization depends on top-down input from the language system to the visual cortex. We directly tested this hypothesis by assessing color categorization in a stroke patient, RDS, with a rare, selective deficit in naming visually presented chromatic colors, and relatively preserved achromatic color naming. Multimodal MRI revealed a left occipito-temporal lesion that directly damaged left color-biased regions, and functionally disconnected their right-hemisphere homologs from the language system. The lesion had a greater effect on RDS’s chromatic color naming than on color categorization, which was relatively preserved on a nonverbal task. Color categorization and naming can thus be independent in the human brain, challenging the mandatory involvement of language in adult human cognition
