Russian Orthodox Churches In Alaska, Stephen M. Straight

The Geographical Bulletin

The only remaining evidence that Russians once occupied Alaska are the 78 Russian Orthodox churches are chapels located on the Aleutian Peninsula and coastal Alaska. A popular tourist attraction, the architecture of these churches are copies those of mainland Russia. Russian orthodox churches are noted for their onion dome styles, but several variations do exist. Modification in church design was often dictated by climatic conditions. Gale-force winds encouraged construction of low structures. Heavy snowfalls led to the design of steep roofs and steeples. St. Michaels Russian Orthodox Cathedral in Sitka burned down in 1966. Rebuilding it has caused a religious …

The Failure Of Beaver Dams And Resulting Outburst Flooding: A Geomorphic Hazard Of The Southeastern Piedmont, David R. Butler

The Geographical Bulletin

Beaver are geomorphic agents through their building of dams and creation of pond environments. In the southeast United States, the successful reintroduction of beaver has vastly increased the number of ponds impounded by beaver dams. These dams may fail, producing rapid and potentially catastrophic draining of beaver ponds, a geomorphic hazard which has not gained sufficient notice. This paper examines several cases of known dam failure and subsequent rapid drainage of beaver ponds. Reconstructions of the discharge from these ponds was accomplished using standard hydrologic relationships of stream dimensions or pond volume to discharge. Peak flood discharges may be catastrophically …

Editorial Comments The Old Homestead, Fred B. Kniffen

The Geographical Bulletin

In a less restrictive sense the same is true of our modern households. All the basic needs common to man the animal must be provided for. However, our great technical advancement over primitive peoples permits a variety of ways in which we shape our shelters, prepare our foods, and supply needs we were not even aware of a century ago. We have radio, TV, and kitchen appliances to perform tasks accomplished by hand when I was a lad. Let me illustrate by example. As a boy in the first years of the century I lived in a modest village on …

Assessing The Feasibility Of Microneedle Patches For Gnrh Immunocontraception In Mixed-Breed Dogs (Canis Familiaris), Ai-Mei Chang, Hsiao-Hui Huang, Ding-Liang Hou, Zi-Yu Lin, Mei-Chin Chen, Chen-Chih Chen, Jai-Wei Lee

The Thai Journal of Veterinary Medicine

The overpopulation of free-roaming dogs poses significant risks to endemic species, public health, and the environment through predation and disease transmission. While surgical castration is effective, it raises ethical concerns regarding animal welfare. Immuno-castration offers a humane and effective alternative for population control, but a more easily administered and cost-efficient method is needed to enable widespread vaccination efforts. In this study, we aimed to employ self-dissolving microneedle patches for a simple and potentially cost-effective immunization of a recombinant GnRH-based vaccine to control fertility. Eight mongrel dogs were randomly divided into 2 groups (n=4 each) and immunized with the recombinant GnRH-based …

Assessing The Micro- And Macroscopic Changes Of Taphonomically Altered Bone, Shelby Feirstein

UM Graduate Student Research Conference (GradCon)

Forensic identifications may be hampered when perpetrators find unique ways of obscuring their victims’ identities, such as fire and household corrosive substances. Thermal alteration, sodium hydroxide, and hydrochloric acid are known to change both the structural integrity and composition of skeletal elements; but the patterns of these processes, nor how each may affect the potential for obtaining identifying DNA data, are well understood.

Burned bone concomitantly follows a defined color spectrum and eventually reaches calcination, consisting only of its original inorganic mineral, hydroxyapatite, which is naturally white in color and brittle.

In contrast, analyses of chemical exposure focus on total …

Impact Of Acute Stress On Circadian Rhythm Regulation Of Locomotor Activity In Syrian Hamsters, Raquel A. Villarreal, Laura E. Garcia, Mario Gil

Research Symposium

Background: Disruptions of circadian rhythms, caused by factors such as environmental changes or stress, are linked to health conditions, including metabolic disorders, cardiovascular diseases, and mood disorders. Circadian rhythm disturbances are particularly relevant for understanding the etiology of conditions like insomnia, depression, and anxiety. The circadian rhythm, primarily regulated by the suprachiasmatic nuclei (SCN) in the hypothalamus, coordinates biological processes to align with daily environmental cycles. Acute stress, especially when experienced immediately upon waking, has been shown to disrupt these rhythms, impair sleep regulation, and exacerbate mood dysregulation. Given the significant clinical implications, understanding how stress impacts circadian rhythms is …

Osmosis Magazine

Imagine living with another organism in your body, cohabiting for months before you are even aware of its presence. Slowly, a lesion starts to form on your leg. The lesion grows bigger everyday, starting at a couple millimeters but growing up to a couple centimeters. The burning sensation starts with the lesion and can only be dimmed by submerging your leg in water. Suddenly, a worm emerges from the lesion along with pus and blood. The patient is infected with Guinea Worm Disease.

The Science Of Tattoos, Isabel Dilandro

Osmosis Magazine

From face paint to temporary stick-on tattoos, children are taught that art on bodies is something beautiful and playful, associated with memories of fun and joy. Why is it then that tattoos get such an infamous reputation? The answer is pretty simple: tattoos are not temporary. But why? How does the ink get there? How does it stay put? In order to understand this process a bit more, it is important to have a basic understanding of the skin’s structure and function.

The Asu Tribe And Customs, Isabel Dilandro

Osmosis Magazine

Chandra Thapar, an Indian anthropologist, dedicated a portion of his career to the study of foreign cultures and how they relate to his native country. One in particular caught his specific attention due to its similarities in the reverence of a sacred animal, akin to how the cow is sacred to India. See below a short consolidation of his findings:

The tribe Dr. Thapar studied is called the Asu and is found on the North American continent north of the Tarahumara of Mexico.

Kennewick Man: A Rare Window Into Prehistoric Life In North America, Jack Dupuy

Osmosis Magazine

What would you do if you found a human skull on the banks of the James River? On July 28, 1996, two college students stumbled across a skull on the banks of the Columbia River in Kennewick, Washington. They believed it was a murder victim at first, but archeologists and scientists discovered that the skull was part of a nearly complete, 9,000 year-old skeleton.
