Perturbative Color Transparency in Electroproduction Experiments

We calculate quasi-exclusive scattering of a virtual photon and a proton or pion in nuclear targets. This is the first complete calculation of ``color transparency" and "nuclear filtering " in perturbative QCD. The calculation includes full integrations over hard interaction kernels and distribution amplitudes in Feynman -x fractions and transverse spatial separation space $b$. Sudakov effects depending on $b$ and the momentum transfer $Q^2$ are included. Attenuation of the hadronic states propagating through the medium is calculated using an eikonal Glauber formalism. Nuclear correlations are included explicitly. We find that the color transparency ratio is comparatively insensitive to theoretical uncertainties inherent in perturbative formalism, such as choice of infrared cutoff scales. However, the $Q^2$ dependence of the transparency ratio is found to depend sensitively on the model of the distribution amplitude, with endpoint-dominated models failing to be dominated by short-distance. Color transparency experiments should provide an excellent test of the underlying theoretical assumptions used in the pQCD calculations.Comment: 16 pages LaTeX, 9 ps figures.

Non-formal education and grassroots development : a case study from rural Bangladesh

Through the case study of Gono Unnayan Prochesta (GUP), Voluntary Organization (VO) operating in rural southwestern Bangladesh, this thesis explores the role of non-formal education for empowerment and socio-economic development. The issues examined are the mobilization process and the grassroots organization of disadvantaged women, education for regenerative agriculture, functional literacy and women's health. The case study focuses mainly on two womens groups. During the field work part of the study, most men were away from the villages in pursuit of salaried jobs or carrying out their small trades. The study adopted the framework of analysis proposed by Moser (1993) about the productive, reproductive and community roles of women in the context of their practical and strategic needs. The data indicates that due to the extreme poverty situation in the study area, addressing practical needs is considered more urgent by the women who were interviewed. Furthermore, they indicated that the center-based functional literacy training is less effective than the home-based training related to health and agriculture issues. It also was observed that the gosthi (lineage) shanskriti (cultural) and para (neighborhood) identities are essential elements in mobilizing the women's groups in the villages. After 25 years of GUP's activities, grassroots women's organizations are yet to be self-sustaining in the villages of Rajoir. The women participants in this study understand the importance of learning how to sign their names for access to small loans, although they indicate that further functional literacy does not meet their immediate practical needs. They are aware of the value of literacy and formal education for their children. Even then, the immediate projects they finance with small credits and loans available to them are still distributed alone traditional gender roles; seed money for starting small businesses for their sons or dowry needs

Resident Education in Principles and Technique of Bowel Surgery Using an Ex-Vivo Porcine Model

Objective. improve competency of residents with lysis of adhesion (LOA) and bowel surgery using a porcine model. Study Design. Pig bowel was removed at time of an anatomy laboratory, cleansed, and used to demonstrate surgical techniques and principles of LOA, repair of enterotomy, bowel resection, and anastomosis. Participants were surveyed pre- and posttraining session using 10 point Likert scale. Results. Thirty one residents at varying levels of training participated. After the training session, there was a significant improvement noted in mean scores for comfort level with LOA (6.3 versus 7.7, P = .007), comfort level with enterotomy repair (2.8 versus 6.4, P < .0001), understanding principles of LOA (5.0 versus 7.7, P < .0001), understanding principles of enterotomy repair (3.5 versus 7.0, P < .0001), and familiarity with instruments used (5.8 versus 7.3, P = .01). Conclusion. Training sessions using ex-vivo porcine model improve resident perception of knowledge and comfort with LOA and enterotomy repair

UC-14 TeleClinic

TeleClinic is a telemedicine web application that provides ease of access and a medium for interaction between patients and their respective doctors and administrators. In particular, this web portal includes a chat feature, an area for medical reports, an area for appointment requests, and an area for video recordings. Additionally, TeleClinic meets the requirements prescribed by the Health Insurance Portability and Accountability Act (H.I.P.A.A.) via upholding data privacy and safeguarding medical information. To maximize its overall utility, TeleClinic utilizes the React and React Redux libraries for its front-end and a NoSQL database in Google Firebase for its back-end.Advisors(s): Dr. Ken HogansonTopic(s): IoT/Cloud/NetworkingCS 485
