Effects of Photoperiod on the Occurrence of Symbiotic Rotifers, Nematodes and Branchiobdellids of Two Orconectid Species of Crayfishes
Representative specimens of O. immunis and O. pellucidus were brought to the laboratory in order to investigate the influence of light on the occurrence of the symbionts encountered during the preliminary field study. After one week of acclimating the crayfishes they were distributed among environments control chambers that permitted exposure of the hosts and symbionts to 1) continuous light (C.L.), 2) a daily cycle of 12 hours of light and 12 hours of darkness (12L-12D) and 3) continuous darkness (C.D.)
History of the King\u27s Daughters Home for Incurables, Louisville, Kentucky, 1909-1948.
This study traces the growth and development of The King\u27s Daughters Home for Incurables, Louisville, Kentucky, from its beginning up until the end of 1948 and looks forward to future plans that may seem appropriate. Members of the Board of Directors desired such a study be made as a means of drawing together the past work of their organization. They also looked to the study as being a help in making future plans for the continuation of their work

Characterising two-pathogen competition in spatially structured environments
Different pathogens spreading in the same host population often generate
complex co-circulation dynamics because of the many possible interactions
between the pathogens and the host immune system, the host life cycle, and the
space structure of the population. Here we focus on the competition between two
acute infections and we address the role of host mobility and cross-immunity in
shaping possible dominance/co-dominance regimes. Host mobility is modelled as a
network of traveling flows connecting nodes of a metapopulation, and the
two-pathogen dynamics is simulated with a stochastic mechanistic approach.
Results depict a complex scenario where, according to the relation among the
epidemiological parameters of the two pathogens, mobility can either be
non-influential for the competition dynamics or play a critical role in
selecting the dominant pathogen. The characterisation of the parameter space
can be explained in terms of the trade-off between pathogen's spreading
velocity and its ability to diffuse in a sparse environment. Variations in the
cross-immunity level induce a transition between presence and absence of
competition. The present study disentangles the role of the relevant biological
and ecological factors in the competition dynamics, and provides relevant
insights into the spatial ecology of infectious diseases.Comment: 30 pages, 6 figures, 1 table. Final version accepted for publication

Zoonotic Diseases—Fostering Awareness in Critical Audiences
Zoonotic diseases are infectious diseases that are shared between humans and other vertebrate animals. Extension professionals often serve as consultants and educators to individuals at high risk of zoonotic diseases, such as participants in 4-H livestock projects. Effective education about zoonotic diseases begins with an awareness of the multitude of challenges that health care professionals face in diagnosing zoonotic disease. This review describes the factors that influence diagnosis of these diseases, as well as potential methods that the Extension professional can use to convert those challenges into effective educational messages
Russias Influence In Africa: Scenarios To Inform Greater Democratic Resilience
This paper is the result of a scenario-building exercise that NDI conducted in October and November 2022 with African, American and European analysts. Through the exercise, NDI sought to better understand potential trajectories of Russian influence in Africa over the next three years (2023–2025), especially developments that could have implications for democracy on the continent. This scenario exercise involved: background papers on various aspects of Russia's engagement in Africa; an online scenario-building workshop with African, American and European analysts; the development of four scenarios, each reflecting a different possible future identified during the online exercise; and further refinement of the scenarios based on consultations with selected analysts. Each of the four scenarios reflects a different combination of two key uncertainties: Russia's capacity to project power in ways that undermine democracy in Africa and the opportunities for Russia to do so
A Land-Use and Water-Quality History of White Rock Lake Reservoir, Dallas, Texas, Based on Paleolimnological Analyses
White Rock Lake reservoir in Dallas, Texas contains a 150-cm sediment record of silty clay that documents land-use changes since its construction in 1912. Pollen analysis corroborates historical evidence that between 1912 and 1950 the watershed was primarily agricultural. Land disturbance by plowing coupled with strong and variable spring precipitation caused large amounts of sediment to enter the lake during this period. Diatoms were not preserved at this time probably because of low productivity compared to diatom dissolution by warm, alkaline water prior to burial in the sediments. After 1956, the watershed became progressively urbanized. Erosion decreased, land stabilized, and pollen of riparian trees increased as the lake water became somewhat less turbid. By 1986 the sediment record indicates that diatom productivity had increased beyond rates of diatom destruction. Neither increased nutrients nor reduced pesticides can account for increased diatom productivity, but grain size studies imply that before 1986 diatoms were light limited by high levels of turbidity. This study documents how reservoirs may relate to land-use practices and how watershed management could extend reservoir life and improve water quality
Flotation therapy for downer cows
Cattle that become recumbent (unable to get up) as the result of calving difficulty, low blood calcium, traumatic injuries, or other disorders are prone to develop subsequent pressure damage of muscles, nerves, and areas of skin. The resulting medical problems that are secondary to prolonged recumbency may be more life-threatening than the initial medical disorder that caused recumbency. Flotation therapy is an effective means of physical therapy for rehabilitation of downer cattle. A description of flotation therapy and data from the first year of use of the flotation tank at the Veterinary Medical Teaching Hospital, Kansas State University, are presented.; Dairy Day, 1996, Kansas State University, Manhattan, KS, 1996
Evaluation of semen collected from commercial rams by electro-ejaculation
Annual ram pre-breeding soundness examinations (PBSE) are accepted as an integral component of veterinary flock health planning to identify rams not capable of achieving high conception rates. This preliminary study collected information from 280 rams presented to five veterinarians for routine PBSE on commercial farms in England in 2013. The study compared the outcome of a physical examination, which included palpation of external genitalia, with the gross and progressive motility of the semen produced by electro-ejaculation
