Ostracod Species

Between 2015 and 2017, 58 ostracod taxa were collected at 30 locations in 111 samples from the hyporheic zone of surface streams in Texas, U.S.A. Six new species (Bradleycypris foresteri n. sp., Bradleystrandesia macula n. sp., Pseudocandona lordi n. sp., Indocandona rusti n. sp., Stenocypris sancari n. sp., Cyclocypris dalyana n. sp.) are described based on carapace and soft body parts. Additionally, 17 species and two genera (Vestalenula and Indocandona) are presented as new records for Texas, and Indocandona rusti n. sp. is the first record of the genus outside India. Taxonomic positions of the new species are discussed along with ecological information. One-hundred and six nonmarine ostracod species are now reported from Texas. However, ongoing studies suggest that actual species richness is much higher.

Current Proposal

The use of robots in search and rescue operations has increased dramatically over the years. A robot is able to detect survivors of a dangerous situation, like an earthquake, without putting the operator’s life in danger as well. There are many types of robots being developed for search and rescue purposes, but a smaller and more durable robot will be beneficial for designs in the future. The purpose of our project is to research and design a soft body robot that is capable of locating individuals in search and rescue operations. The robot has a design similar to a car which will allow the control of the robot to be easy to use. It has been designed with a self-righting mechanism in case the vehicle flips over or gets stuck. The robot has a small size so that it can fit through small holes that a person could not enter. The robot will be capable of traversing over uneven terrain, including small ledges through an actuator. The actuator will be designed to cause the robot to spring over or on a ledge. According to simulations from SolidWorks, the wheels of the robot can also withstand a drop from 2 meters. The design and material of the wheels will be further tested and changed to increase the performance of the wheel. Once a design has been chosen, the body of the robot will be designed. Current designs of ground rescue robots will be studied in order to attain a better understanding on what designs work best. The hope is to make the robot more durable than previous designs using a soft material as the outer shell of the robot. A soft material should allow the robot to be able to absorb impacts from falling debris or unexpected falls. Once the design of the robot has been optimized, a prototype will be created. The next step will be to code the robot so that it can be controlled with a remote. The current proposal is to use an Arduino board to send and receive signals from that remote. Then a camera will be attached to the robot which will allow the operator to see where the robot is and where the survivors are located.

Ethological Study

AbstractThe behavior of ten species of strombid gastropods (Strombus and Lambis spp.) was studied in the Marshall, Hawaiian and Line Islands. Measurements were made in both the laboratory and the field of the MAP's comprising feeding, locomotion, righting of overturned shells, and escape from predators, which reflect significant ecological and morphological determinents of behavior in the Strombacea. All species feed by grazing with the proboscis under the protection of the shell. All Strombids use the MAP Leap during locomotion. The rate of locomotion varies as a hyperbolic function of length; increasing with greater size in the genus Strombus and decreasing in the genus Lambis. Larger animals travel a greater distance with each leap but make fewer leaps/minute. Species of Strombus right their overturned shells by a Kick at the substratum with the operculum, but species of Lambis use the MAP Pull and turn the animal over with the operculum wedged under the shell. Only one attempt is needed in the species of Lambis, but more are used by the faster moving species of Strombus. Intention movements are performed during righting. Species of both genera escape from molluscivorous cones using the MAP's Tentacle Wave, Flip and Run. In the species of Strombus, Flip causes a backward movement of the shell off the substratum, but in species of Lambis the shell restricts the movements and the animal merely turns to one side. Escape locomotion is much faster than normal locomotion, due to the greater distances travelled with each flip by the smaller species of Strombus and the greater number of leaps/minute made by all species. The flip escape response appears particularly adapted for escape from dart-shooting predators. A review of the literature on strombid behavior shows that the behavior of all species within the Strombacea is remarkably similar even though there is great disparity in shell shapes. Because of similarities in soft body parts and behavior, the Xenophoridae should be retained within the Strombacea. It is suggested that the species within the Strombacea evolved in parallel from a common aporrhaid-like stock and the behavior has diverged less than shell form and is therefore a more conservative character in the group's phylogeny than is shell shape. The behavior of a snail can be greatly modified by its shell. Differences in behavior between Strombus and Lambis are attributed to restrictions imposed by the shell and not differences in body movements. Behavior must be adapted to the shell shape and both, of course, reflect the animal's ecological setting.

Some futuristic technologies belong to a distant time that is hard for most to imagine in palpable terms. In the case of 3D printing, however, any citizen can easily grasp the stakes by simply watching a brief video (). The 3D printer, whose ancestry can be traced to factory innovations of the 1980s, provides a method of assembling objects piece by piece: a kind of less precise nanotechnology for the macro-level. Within a decade humans might be able to print functional body parts, bringing an end to the grisly waits for donated organs and the even more grisly international organ trafficking rings. Some believe that the “killer app” for 3D printing will be found in the printing of food, perhaps replacing single-site restaurants with a home library of Platonic forms of gourmet cuisine. Still others celebrate or fear the printing of assault rifles on a desktop, whether by right-wing citizens, convicted felons, or the mentally ill. One can expect the easy availability, in residential privacy, of all manner of benign and malignant objects, transforming economic structures, social life, and domestic security in roughly fifteen to twenty years.

Fractures of complex body parts are often serious and difficult to handle, and they have high technical and training requirements. However, the realistic situation is that there are few opportunities for the junior residents, trainee doctors, and especially medical students to contact enough clinical practice and see such fracture patients. Fortunately, with the rapid development and continuous progress of 3D printing and related technologies, this situation has gradually gotten better and better. In this research, we confirmed that 3D printing technology could improve the effectiveness of fracture teaching and medical learning from multiple dimensions. We comprehensively screened and assessed 223 papers from the Web of Science (WoS) Core Collection on October 3, 2021, with “((3D) AND ((printing) OR (printed)) AND (fracture)) AND ((education) OR (training) OR (teaching))” as the retrieval strategy. Additionally, we used the VOSviewer software to analyze the keywords and countries and the organizations of the publications, then a series of scientometric and visualized analyses were made based on the retrieval results. Afterward, multiple databases were retrieved according to our selection criteria, we selected eight studies for the extensive literature analysis. The extracted data contained information of authors, problems solved, participants, methods, assessments, results, and benefits/limitations. These intuitive and in-depth analyses further confirmed and appraised the advantages of 3D printing in complex fracture models more objectively. In conclusion, 3D printing could improve the effectiveness and extension of fracture teaching, as well as medical learning, by providing the powerful interaction with 3D effect, wakening students learning interest, and allowing the junior residents, trainee doctors to have as realistic a virtual practice experience as possible. Through this research, it is expected that more researchers could be attracted to conduct more comprehensive and thorough studies on the application of 3D printing for training and educational propose, to promote the development of 3D technology-based medical education practice and further deepen the reform of medical education and improve the quality of fracture education and learning.
