Frederick, Paul; Ferrell, Josh. EFFECTS OF PARKING LOT RUN-OFF ON TADPOLE SURVIVORSHIP AND GROWTH.

Using microcosms (12 cattle tanks), we tested the effects of parking lot run-off on chorus frog tadpole survivorship and growth. We had three treatments: control, 50% parking lot water, and 100% parking lot water. Significantly more tadpoles survived in the control than in either of the parking lot water treatments. Also, the mean mass of tadpoles from the control was significantly greater than in the 100% parking lot water treatment.

Campbell, Jesse; Garvey, Amber; Grieshaber, Brandon; Stegall, Ashley. CAFFEINE-INDUCED APOPTOSIS ON INTESTINAL EPITHELIAL CELLS.

The affect of various concentrations of caffeine on intestinal epithelial cells was tested. We hypothesized that cell apoptosis would be observed after exposing the cells to a concentration of 4 mM of caffeine over a 48-hour period. All twelve of the wells exhibited apoptosis however we were unable to conclude that the apoptosis was induced by caffeine. We suspect that the apoptosis that occurred in all of our wells was due to the length of the cells exposure to caffeine, and/or that the 48-hour period was too long for the cells to live without their nutrient source being replenished.

Kristina Campbell, Jasmine Colon, Abbey Williamson. EFFECTS OF DIFFERENT TYPES OF YEAST ON FERMENTATION RATES.

We compared the fermentation efficiency of three different commercial yeast brands. Our hypothesis was that the fermentation of glucose by active dry yeast, rapid rise yeast, and pizza crust yeast occur at the same rate. The experimental results did not support our hypothesis. Instead it showed that the rapid rise was the fastest and the pizza crust was the slowest at producing carbon dioxide.

(Dear, Matt) (Brown, Tim) (Cotton, Adam). WHITE NOSE SYNDROME IN NORTH AMERICAN BATS.

White Nose Syndrome (WNS) is a disease that affects hibernating bats. It earned the name White Nose Syndrome because of the white fungus that grows on the muzzle and other parts of the bat. WNS has been attributed to mass mortality of bats in the eastern United States. Since being discovered in 2006 WNS has spread to the midwest and even into Canada. Bats with WNS display very odd behaviors such as flying around during the day or clustering near the entrance of caves. It has been estimated that WNS has killed well over 5 million bats nationwide.

Dysart, Kayla; Hahn, Kayley; McFarlin, Shane; Musser, Terry. APOPTOSIS INDUCTION OF INTESTINAL EPITHELIAL CELLS USING CHLORHEXIDINE.

Chlorhexidine is an antiseptic used in wound dressing and mouthwashes that has been known to induce apoptosis in large quantities. The purpose of this experiment was to see if chlorhexidine induced apoptosis in an intestinal epithelial cell line (CMT-93). DNA isolation and fragmentation was used to determine the induction of apoptosis in a control and two different concentrations of chlorhexidine (0.5%, 1.0%). Necrosis of the cells occurred instead of apoptosis in the 0.5% and 1.0% concentrations concluding that chlorhexidine actually induces necrosis as opposed to apoptosis in high and low concentrations.

Many carbonated drinks are very popular in the United States, however an increasing number of scientific papers point out the negative impacts of these drinks. We investigated the relationship between the pH and the temperature of 10 different common drinks including Milk 2%, Root Beer, Gatorade, Diet Pepsi, Pepsi, Diet Coke, Coke, Almond Milk, Lemonade, and Orange Juice. We found, that heating the drinks has a slight impact on their pH, in particular in the case of the carbonated drinks. We attribute this effect to the impact of temperature on the solubility of CO2, forming hydrocarbonic acid in solution.

Hanttlua, Natassja; Koy, Karen. PROGRESSIVE TAPHONOMY OF VERTEBRATES IN TEMPERATE TERRESTRIAL SETTINGS.

In the summer of 2012, seven juvenile pig carcasses were placed in either a prairie or forest setting. After the majority of soft tissue had decayed, the exposed bones are being monitored biweekly. Four carcasses are placed in an enclosure in a prairie setting. Three carcasses, including two which had been exposed to fire, were placed in an enclosure located at the edge of a forest. The enclosures exclude large scavengers, such as dogs and humans, but allow insects and smaller scavengers, such as raccoons and opossums, to access the carcasses. Missing and damaged bones were noted and photographed. Each week the skull, mandible, scapula, pelvic wings and long bones are evaluated for taphonomic grade, using the Behrensmeyer evaluation criteria. The criteria are being modified slightly to account for differences in bone decay seen in the juvenile carcasses.

Michael Haynes, Jeffrey Meyer, Alesha Matthes. THE IMPACT OF SALT AND NICOTINE ON FERMENTATION..

We investigated the impact of salt and liquid nicotine on yeast fermentation rate. We found, that both NaCl and nicotine stimulated the yeast fermentation rates, which was surprising, as we hypothesized that nicotine could be toxic to cells, while the high salt concentration was expected to alter the cell?s water balance. We expected cells to loose water due to osmosis, and consequently to exhibit fermentation rates lower than the controls. Future research will address the mechanism underlying the observed effects.

Brenna, Knott . DOES LPS STIMULATE COLLAGEN PRODUCTION?.

Collagen is the main structural protein of connective tissue and mostly found in fibrous tissues, such as tendons, ligaments, cartilage, corneas, blood vessels and skin. Fibroblasts are the most common cells which produce collagen. Lipopolysaccharide (LPS) is the main component of the outer membrane of Gram-negative bacteria. Current research uses LPS to induce synthesis and secretion of growth promoting factors such as interleukins. In this study, two forms of collagen were reversely transcribed and PCR was performed to determine which sample would provide better data. A negative control, LPS, TGF-? and IGF were then introduced to cultured myofibroblasts to induce collagen control. Cells were treated with these hormones; RNA was isolated from the myofibroblasts and was reversely transcribed to DNA before running realtimePCR on the DNA.

Musser, Terry. SCHISTOSOMIASIS BY ROUTE OF SCHISTOSOMA MANSION.

Schistosoma mansnoi is one of the causative agents of schistosomiasis. It is a blood fluke and is most common of all the schistosomes of infecting humans. It is transmitted through contact of free-swimming cercariae. These cercariae come from an infected snail host of the genus Biomphalaria. The life cycle starts and ends with the contact of contaminated feces in a water source where this snail is found. This paper will attempt to outline the major characteristics of Schistosoma mansoni and its effects on humans as a host for the parasite. Details on treatment and prevention will be provided to help educate on the importance of sanitation.

Owens, Darcy Davis, Courtney. MEDICAL USES FOR NEUROTOXINS FROM POISONOUS ORGANISMS.

In general, the classes of toxins that are found in most animals and their skin are alkaloids toxins and are found in amphibians. An alkaloid is a complex organic compound containing nitrogen. They are commonly derived from amino acids, and originate from alkynes which is why it has a bitter taste. Just touching the frog will not immediately impair you, there needs to be contact and entry into the system via the blood or by mucous in order to do any harmful damage. Scientists have revealed that batrachotoxin is not an immediate blocker of the nervous system and actually makes the heart muscle contractions stronger initially while the pumiliotoxin in positively utilize to the toxin. The national Institute of Health is undergoing research used derivatives of the batrachotin for anesthetics in surgery. Explorations in the fields involving these natural toxins is important for the human development and further research will benefit the world of science.

Streett, Brooke . EAST AFRICAN SLEEPING SICKNESS: A HISTORICAL REVIEW.

East African Sleeping Sickness is a rare form of African Sleeping Sickness, but is very dangerous because it has an acute onset. The etiological agent associated with the disease is Trypanosoma brucei rhodesiense. Its symptoms occur quickly and, if left untreated, can result in death. Not only does this disease kill, but it also had an effect on the quality of life and the economy. The disease is often treated with suramin or melarsoprol depending on the pathology. The vector that spreads the parasite is the tsetse fly. Finding ways to control spreading of East African Sleeping Sickness include: controlling vector populations, altering human activities, and replacing livestock with a resistant species to the Tsetse fly. The disease?s history has dated back to early African civilizations.

Understanding photosynthesis response to freshwater acidification is key to better understand how acid rain events will affect freshwater ecosystems. We were interested to study how a decrease in the pH of pond water could affect the photosynthesis of the aquatic Elodea plant. We found that the lower pH level resulted in a higher photosynthetic rate, which was an unexpected result. Further research will investigate the mechanism of the observed response.

Water runoff from agricultural fields to ponds could potentially contaminate the pond ecosystem with fertilizers, salts, etc. The purpose of the experiment was to understand the effects of salt water and Miraclegro, a common fertilizer on the photosynthesis of Elodea. We hypothesized that the Miraclegro and salt solution would have similar effects Elodea cells, potentially providing a hypertonic environment which was expected to induce plasmolysis in the cells. The results show that salt indeed plasmolyzed the cells of the aquatic plant, while the fertilizer addition did not result in plasmolysis, and stimulated photosynthetic O2 evolution.

William Walker, Dillon Howe . THE EFFECTS OF TERPENOID PLANT HORMONES ON PLANT GROWTH AND DEVELOPMENT.

In this in-class Plant Physiology (BIO 340) project we investigated the impact of two, exogenously applied plant hormones, abscisic acid (ABA) and gibberellic acid (GA3) on plant growth and development. Plant morpho-physiological characteristics (leaf development, plant height, internode length and root development) were assessed at the start and the end of the experiment.? Results show that GA3 stimulated plant growth, and contrary to our expectations, plants treated with ABA were also taller than the corresponding controls. We hypothesize this response to be the indirect effect of ABA action on plant stomata. Exogenous application of ABA was previously described to induce stomata closure in leaves, which is likely to have improved plant water use efficiency and decreased transpiration rates, allocating more resources to the vegetative development of the plants.

Romesburg, Kayla. SCHISTOSOMIASIS BY WAY OF SCHISTOSOMA JAPONICUM .

Schistosoma japonicum is a major infectious agent of the disease schistosomiasis. Schistosomiasis is caused by parasitic worms that can infect the urinary tract or intestines. Schistosoma japonicum happens to infect the small intestine of humans. Schistosoma japonicum is very similar to Schistosoma mansoni, but is the most pathogenic of the Schistosoma species because it produces up to 3,000 eggs per day which is ten times greater than that of Schistosoma mansoni. The parasite?s life cycle begins with interaction of contaminated feces in or near water where the snail hosts of the genus Oncomelania is found. Schistosoma japonicum is transferred through free-swimming cercariae interaction. This paper on Schistosoma japonicum will describe the physiognomies of this parasite, the effects it has on humans, and how prevention of this disease can be taken into account by ways of better sanitation in communities.

Bracke, Ashley. AN HISTORIC REVIEW OF THE GUINEA WORM (DRACUNCULUS MEDINENSIS).

Dracunculiasis, also known as guinea worm disease, is caused by the large female of the nematode Dracunculus medinensis, which emerges painfully and slowly from the skin, usually on the lower limbs. The disease can infect animals, and sustainable animal cycles occur in North America and Central Asia but do not act as reservoirs of human infection. It has a significant socioeconomic impact because of the temporary disability that it causes. Guinea worm infection is one of the most easily prevented parasitic diseases, but it is nevertheless a cause of disability in rural areas of Africa. Dracunculiasis is exclusively caught from drinking water infested with infected Cyclops (a microcrustacean), usually from ponds. A campaign to eradicate the disease was launched in the 1980s and has made significant progress. The disease is endemic across the Sahel belt of Africa from Mauritania to Ethiopia where they do not have access to safe drinking water, and has been eliminated from Asia and some African countries. Worms up to 70-80 cm in length develop in the subcutaneous tissues of the feet or legs and larvae are progressive to repeat the cycle when an infected individual steps into a well or pond from which others draw drinking water. The disability may be economically very important if the period of infection coincides with busy periods in the agricultural year.

Ectotherms body temperature is generally a product of their environment. Endotherms body temperature is generated by metabolism. This will be a discussion on the many lines of argument that would lead a scientist to believe that dinosaurs were in fact endotherms versus being an ectotherm.

Jacobs, Julia. MEDICAL PARASITOLOGY REVIEW: TAEINA SOLIUM.

Taeina solium is an intestinal zoonotic parasite commonly known as the pork tapeworm. This tapeworm is transferred to pigs, the intermediate host, through human feces and then passed to humans, the definitive host, through measly pork. The adult Taeina solium is a white, ribbon like, 2-3 meter long triploblastic acoelomate, meaning it has no body cavity. This tapeworm is also known for having an armed rostellum containing 22-32 hooks that allows it to attach itself to the intestinal wall of its host. This parasite can be found worldwide, in any area that commonly eats pork and can easily be prevented and controlled by fully cooking meat and proper disposal of human feces around pigs.

Salamander populations have been on decline all over the world. The cause of decline in salamanders are many factors that affect amphibian populations to varying degrees, including habitat loss and degradation, climate change, pollution, increased ultraviolet B (UV-B) radiation, direct exploitation, introduced species and disease, including infectious disease. Studies producing trends of salamander decline are increasing and extensive research is needed to help global amphibian diversity. If this issue is not addressed many salamanders could go extinct which could cause substantial effects on the surrounding habitats.

Some of the most important features of the sky islands are the remote subpopulations surviving on the tops of these ranges. Most are simply an isolated branch of a larger population occurring elsewhere, but some have been isolated for so long that speciation has set in. A few of these new species are so new and have such small populations that they don?t even have common names yet, but are quickly becoming key players in management and conservation issues on the sky islands. The following is an examination of a few sky island species and subspecies that are isolated both genetically and geographically; and what these small, unique populations mean to those who manage their habitats.

Gutteridge, Katelyn and Callen, Sean. HYPERBOLIC'S NEXT TOP MODEL.

Only five axioms define Euclidean geometry, changing one of those can create a ?new? geometry. Hyperbolic geometry is created by replacing Euclid?s fifth Axiom, which states that there is only one line through a point that is parallel to another line. By allowing at least two lines through a point to be parallel to another original line, hyperbolic geometry can be modeled. There are many ways to model hyperbolic geometry, including the Poincare Disk Model, Half-Plane Model, and the Klein Model. Here these three models are compared in both construction and theory to prove that they are isomorphic.

Our group looked at Tolkien?s famous story about a special ring and tried to decide, in our own words, what might be some of the character's payoffs if they had decided to take different actions, and if some key players did not help as much as they originally did. We assigned payouts to Frodo Baggins, Samwise Gamgee, and Bilbo Baggins. Frodo could choose between going to Mordor or taking the ring for himself. Samwise could choose between going with Frodo or staying in the Shire. Bilbo could choose between going to Rivendale or going to the Mountains. Also, we thought about if only Gandalf helped Frodo in any situation he choose and if Gollum only stayed and played tricks on Goblins. From there, we used Nash?s Equilibrium Theorem to figure what the Hobbits would have done if they were rational.

In Euclidean geometry, every triangle contains three specific points: the circumcenter, the orthocenter, and the centroid. The circumcenter is a point where the perpendicular bisectors of the triangle intersect, the orthocenter is a point where the altitudes intersect, and the centroid is a point where the medians intersect. These three points all lie on the same line, known as the Euler line. This line was discovered by and named after Leonhard Euler in 1765. We will show the proof of the Euler line?s existence in Euclidean geometry and discuss this idea in hyperbolic geometry as well.

In this study, an eleven question survey that incorporated a Likert-type scale was sent out to 18 employees of the agency. Overall, the results of this study do not indicate a significant relationship between awareness and utilization, or value and utilization. However, this study was limited to only a small convenience population. Were this study duplicated in the future, it would be a good idea to use a larger random sample of several different circuits across the state to increase the accuracy and reliability of the results.

This study explored whether clients found that the twice yearly doctor visits and case manager assessments were adequate enough to meet their needs both medically and non-medically. The sample was obtained through the case manager?s client list. A 23 multiple-choice question survey was mailed out to 45 clients in the fifteen county area the agency serves. A total of 16 surveys were mailed back. Questions asked about demographics, CD4 counts, medical and non-medical needs, and overall satisfaction with the case management they are currently receiving. Results show that the majority of clients find the twice yearly doctor visits and case manager assessments enough to meet their needs. In conclusion, it?s important to frequently re-evaluate case management practices, even those federally funded, to ensure clients are getting the care and attention they need.

This study explored the effects of custody in divorce on the parent-child relationships. I did research over the topic, and conducted a questionnaire. The questionnaire was sent to twelve individuals, some were parents and others were children of divorced families. The results of the questionnaire showed the best custody arrangement differs with each situation. To keep a strong relationship with both parents, a joint custody arrangement is best. However, it is only really successful if the parents are willing and able to get along with each other. The child can sometimes feel stuck in the middle with joint custody. Sole custody tends to create a very strong relationship with only one parent, normally the parent with custody. They usually have a weak relationship with the parent without custody. Parents tend to wish for joint custody for the child's sake, but are happier with a sole custody arrangement.

The purposes of this research assignment were to determine how family life is affected when there is a defiant child in the family?specifically, how the parents and the siblings are affected?and to distinguish the different types of treatments used to treat defiant children. I created a survey on this specific topic. The overall findings of this survey were that most of the families who conducted the survey had children who acted out verbally because they wanted attention, jealousy, were frustrated by their disorder, lack of structure/supervision, or for some unknown reason. These defiant children were generally diagnosed with operational defiant disorder (ODD) or an autism disorder. The most used treatment was that of at home treatments via self-help books. After treatments the child generally had good and bad days. Lastly, the effects on the parents were that of arguing or even getting a divorce. Also, half of the parents were worried about their non-defiant children becoming defiant. The overall conclusion to this study is that once the family finds a treatment that best suits the family as a whole, it will help resolve some of the negative effects.

The questionnaire contained quantitative and nominal measures of the variables that related to homelessness. This study addresses the research question, ?What impacts the vulnerability of homeless persons or/and families living on the streets or in shelters?? The empirical data did not support the hypothesis: The greater number of homeless persons living on the streets or in selected shelters that are housed and then homeless again will have a higher vulnerability index score in St. Joseph, Missouri. However, the study showed that homeless persons who were housed and then homeless again received a high vulnerability index. \\r\\n\\r\\n

Memorability is an important aspect of product usability. This project presents evidence as to why comics are more reliable as an instructional device by using a usability/memorability test. It is hoped that people will walk away from this presentation asking questions about how people learn- either through how-to guides or books containing subjects that students learn in school.

Literature Reviews

Cordonier, Erin. DEFENDING TECHNICAL COMMUNICATION: POWER AND STATUS IN A MATURE FIELD STILL OF DUBIOUS WORTH.

I review selections from both volumes of Power and Legitimacy in Technical Communication (edited by Gerald J. Savage and Teresa Kynell-Hunt in 2004), a landmark collection of discussions on the status of technical communication in academia and practice. Next, I review more recent discussions on the topic to determine what has changed and what practices can help technical communicators establish status and power.

Swing, Catherine. WESTERN PRAIRIE FRINGED ORCHID (PLATANTHERA PRAECLARA) PREDICTION MODEL.

Platanthera praeclara, commonly called Western Prairie Fringed Orchid, is a listed threatened species in Missouri. There are three known populations in the Missouri glaciated plains ecoregion: Tarkio prairie CA, Little Tarkio prairie CA, and Helton prairie NA. This plant is native to tall grass prairies and grows in soils with a mutualistic symbiotic relationship with endomycorrhizae fungi. Historically these species occurred throughout the glaciated plains and the Osage plains ecoregions in Missouri. The goal for this research is to examine environmental conditions from the known prairie locations as a means to identify potential future areas for Platanthera praeclara reestablishments.

Wakefield, Calvin. SPATIAL ANALYSIS OF ELK IN THE OZARKS.

Elk have recently been reintroduced to Missouri. There is currently much concern about the habitat and areas the elk will inhabit. Through several GIS processes I analyzed the habitat, elevation, and general area inhabited by an elk in the restoration area. I found the elk favors deciduous forest at no specific elevation range within the designated restoration area.

Walker, William and McIntosh, Timothy. HOME RANGE AND POSSIBLE FUTURE HABITATS OF WHITE FRINGE PRAIRIE ORCHIDS IN THE TARKIO PRAIRIE.

The Purpose of this experiment was to determine the home range of the White Fringed Prairie Orchid, and other possible areas of growth., in the area of the Tarkio Prairie in Atchison County. This was done by using Dr. Ashley?s GPS data of known orchid locations, and by using Arc Map software. It was observed that orchids may prefer an elevation of 1055 to 1070 meters above sea level.

Couch, Brock. USING GIS TO DETERMINE THE SUCCESS OF AMPHIBIAN REPRODUCTION IN MAN-MADE VERNAL POOLS.

Amphibian populations are declining worldwide because of various factors such as habitat destruction and disease. Creating new habitat and/or rehabilitating damaged or lost habitat has become an important tool used to restore amphibian populations. For our study, we were working in Mark Twain National Forest to determine if amphibians will use man-made vernal pools. We were also trying to determine if man-made vernal pools made with a liner vs. no liner will promote amphibian reproduction. To identify the species using each pond, we used calling surveys and collected tadpoles or larvae using traps and dip nets. We found that a variety of different amphibian species used the vernal pools: including, Lithobates clamitans; Lithobates spenocephalus; Anaxyrus americanus; Anaxyrus fowleri; Acris blanchardi; Pseudacris crucifer; Ambystoma maculatum; and Ambystoma opacum. From this data, we further wanted to determine which man-made vernal pools would be most suitable for amphibian reproduction using GIS (ESRI ArcGIS). To this end, we correlated various habitat types or categories to species richness as well as the presence of individual species.

Mendenhall, Olivea; Gaume, Cathi. WHERE IS SCAPHIRHYNCHUS ALBUS?.

Pallid sturgeon can be found in the Missouri and lower Mississippi rivers in Missouri. They are on the endangered species list due to the Missouri river dams, downstream of dams which have altered the river's hydrograph, temperature and turbidity. We used data collected from the Missouri Department of Conservation to find three things 1) overall population distribution in the study area, 2) the distribution of each fish type (wild, hatchery, unknown) , and 3) the density of fish caught at each bend in the river. We used Arcmap to create out different layers for our maps.

Pitcher, Sandra. MECHANISM AT THE BASIS OF MARCESCENCE.

To investigate the ecological consequences and the physiological mechanism at the basis of marcescence, we initiated a long term survey-study on the Missouri Western State University Campus during the winter of 2012-2013, using geographical information systems (GIS) for mapping and identifying marcescent species, with the ultimate goal to describe the molecular mechanism responsible for leaf retaining in the identified species

Hall, Rebecca and Mouse, Christy. SOCIAL MEDIA: DOES IT BREACH SECURITY AND PATIENT CONFIDIENTIALTY.

Social Media: Does it breach security and patient confidentiality? A survey was developed on Survey Monkey and distributed to over 100 participants that work in the Health Information field (HIM), students in the HIM field and general population. The purpose of the study was to gain knowledge of the public and professional participant?s opinion on how secure their health data was when social media was involved in the communication of their care and treatment.

Peterson, Tabitah and Clemens, Charity. WHAT IS THE RELATIONSHIP BETWEEN THE AGE OF A PATIENT AND THE LIKELIHOOD OF THEM USING THEIR PHR?.

The purpose of this study was to identify the ties, if any, between specific demographics of a health consumer to the likelihood of them knowing about and using a PHR. Personal health records aren?t currently being utilized by the majority of health consumers at a rate that one might expect, considering the effect they can have on healthcare. Health consumer surveys were taken and analyzed. Preliminary results show a direct correlation, specifically to age and the likelihood of PHR use. This suggests that providers need to be more active in promoting, educating, and helping their patients with obtaining/maintaining a PHR.

Adams, Tarah; Blair, Ethan; Blanton, Missy; Bouling, Alex; Clements, April; Isom, Gabrielle; Sweiger, Victoria. WEIGHING IN ON UNCONSCIOUS PREJUDICE IN HIRING DECISIONS.

This study examined the relationship between unconscious prejudice and overt discrimination against obese individuals in a resume evaluation task. It used a 2 (primed to believe obesity is due to lack of discipline versus genetic predisposition) x 2 (photo versus none with resume) design. Participants were asked to perform a reading task to ostensibly evaluate reading comprehension. In reality, this was the prime of their beliefs about obesity. Half the readings were about obesity being related to genetics, and the other half about obesity as due to lack of discipline. Participants then evaluated two functionally identical resumes for an accounting job. In the photo condition, one applicant photo was obese and the other of normal BMI. Participants rated both resumes and selected one for an interview. Following the resume evaluation, participants completed the IAT-obesity online, which measures unconscious prejudice against obese individuals. They then completed a questionnaire and were debriefed. Analyses are underway using a 2 x 2 ANOVA on IAT scores and resume ratings, and a correlational analysis connecting IAT to resume ratings will also be conducted. We predict greater levels of unconscious prejudice will result in higher ratings for the thinner candidate, and that this will be amplified in the presence of a photo or priming emphasizing lack of discipline as cause for obesity.
