Biochar is used as a soil amendment for improving soil quality and enhancing carbon sequestration. In this study, a loamy sand soil was amended at different rates (0%, 25%, 50%, 75%, and 100% v/v) of biochar, and its physical and hydraulic properties were analyzed, including particle density, bulk density, porosity, infiltration, saturated hydraulic conductivity, and volumetric water content. The wilting rate of tomato (Solanum lycopersicum) grown in soil amended with various levels of biochar was evaluated on a scale of 0-10. Statistical analyses were conducted using linear regression. The results showed that bulk density decreased linearly (R2 = 0.997) from 1.325 to 0.363 g cm-3 while the particle density decreased (R2 = 0.915) from 2.65 to 1.60 g cm-3 with increased biochar amendment, with porosity increasing (R2 = 0.994) from 0.500 to 0.773 cm3 cm-3. The mean volumetric water content ranged from 3.90 to 14.00 cm3 cm-3, while the wilting rate of tomato ranged from 4.67 to 9.50, respectively, for the non-amended soil and 100% biochar-amended soil. These results strongly suggest positive improvement of soil physical and hydraulic properties following addition of biochar amendment. © 2013 Taylor & Francis.

Bombesin (Bn) is a 14-amino acid peptide isolated from the skin of the frog Bombina bombina. The mammalian homologs of this peptide include three forms of gastrin-releasing peptide (GRP): GRP-10, GRP-27, and GRP-29, and a 10-amino acid peptide referred to as neuromedin-B (NMB). These peptides evoke a number of responses, including hyperthermia, bradycardia, inhibition of gastric emptying and inhibition of food intake, by activating one of three G protein-coupled receptors: an NMB-R or BB1, a GRP-R or BB2 and an orphan Bn receptor subtype-3 (BRS-3) or BB3. Bombesin, GRP, and NMB have a role in the short-term control of food intake. These peptides reduce meal size (MS) and they prolong the intermeal interval (IMI), the time between the first and second meals. Studies have shown that the vagus and the splanchnic nerves in the upper gastrointestinal tract, which communicate with the feeding areas of the hindbrain, are necessary for reduction of MS and prolongation of the IMI by Bn, GRP, and NMB. In addition, one-tenth of the intraperitoneal dose of Bn, GRP, and NMB given in either the left gastric artery, which supplies the stomach, or the cranial mesenteric artery, which supplies the intestine, or the femoral vein, also reduces MS and prolongs the IMI. Thus, a potential neurocrine or an endocrine mode of action for these peptides requires further investigation. © 2013 Elsevier Inc.

Cholecystokinin (CCK) is a hormone secreted by the I-cells of the upper small intestine in response to fat, protein, and some nonnutrients, for example, camostat, and a peptide/neurotransmitter secreted by neurons of the central and peripheral nervous systems. There are multiple molecular forms of CCK, for example, CCK-8, CCK-33, and CCK-58, with an active site located within the first eight amino acids of the carboxyl terminus and with a sulfate group on the seventh tyrosine residue. Physiologically, CCK increases pancreatic secretions and gallbladder and smooth muscle contractions as well as inhibits gastric emptying and food intake. CCK evokes these responses by activating two G protein-coupled receptors: CCK1 and CCK2. CCK1 receptors are located mainly in the alimentary tract and contain two affinity states, high and low, whereas CCK2 receptors are found mainly in the brain. Although a CCK-mediated reduction in cumulative food intake occurs by the activation of low-affinity CCK1 receptors located on vagal afferents, the vagus, and the splanchnic nerves are necessary for the reduction of meal size (MS) and the prolongation of the inter-meal interval (IMI) by CCK. Finally, the reduction of food intake by CCK occurs by three possible modes of action: paracrine, endocrine, and neurocrine; thus far, the data favor a paracrine mode. In addition, the gut, which is the main source of peripheral CCK, contains the first neuronal component that senses the presence of food, the enteric nervous system. The enteric nervous system may have a role in the reduction of MS and the prolongation of the IMI by CCK. © 2013 Elsevier Inc.

The Historically Black Colleges and Universities Research Infrastructure for Science and Engineering (HBCU-RISE) activity within the Centers of Research Excellence in Science and Technology (CREST) program supports the development of research capability at HBCUs that offer doctoral degrees in science and engineering disciplines. HBCU-RISE projects have a direct connection to the long-term plans of the host department(s) and the institutional mission, and plans for expanding institutional research capacity as well as increasing the production of doctoral students in science and engineering. With support from the National Science Foundation, Tuskegee University (TU) will implement comprehensive strategies designed to expand TUs research capabilities and using the research projects to enhance the educational experiences of the students. The combined research and education efforts are expected to expand the participation of groups underrepresented in Materials Science and Engineering and support the nations efforts in building a robust STEM workforce. This project has the potential to be a model for increasing the number of minority students pursuing STEM degree programs and careers and addressing the deficit of female and minority faculty members in the discipline of Materials Science and Engineering.

This project will be carried out in TUs Department of Materials Science and Engineering (MSE) with three components:a) research in nanobiomaterials from natural waste, b) development of a minor course for undergraduates in MSE, and c) support the careers of young faculty members in MSE. The research projects will generate new knowledge about the use of waste materials to produce sustainable products and address the serious environmental issue of dealing with waste products by conducting the following: 1) chemical synthesis and analysis, surface studies, processing and performance evaluation of a variety of nanobiomaterials derived from natural waste; 2) development of biocompatible and biodegradable polymer scaffolds for biomedical applications and 3) development of food packaging polymer composite films with antimicrobial and pathogen resistance. The project will provide start-up funds for junior faculty members and offer a minor in Materials Science and Engineering for all STEM undergraduates at TU with the intention of increasing the pool of students entering the graduate program.

Tuskegee University is implementing the TU CS10K Project in partnership with Auburn University, the University of Alabama, A+ College Ready, the Alabama State Department of Education, the Black Belt Commission, the Exploring Computer Science Program, the Tuskegee University Computer Science Advisory Board, and 19 school districts in the 17 counties that traditionally constitute the historic Black Belt region of the state of Alabama. Computing impacts almost all aspects of our daily lives and its important that students get the opportunity to study computer science (CS) through formal course work in order to excite them about studies and career opportunities in CS. Yet, the vast majority of high school students in Alabama attend schools that do not offer rigorous CS curriculum. To address this, the TU CS10K Project aims to develop, implement, study and evaluate an ambitious project to establish the Exploring Computer Science (ECS) curricula in all 43 high schools of the historic Alabama Black Belt.

The TU-CS 10K Project will prepare 60 in-service teachers for ECS instruction in partnering high schools using the ECS model of teacher professional development (PD): a one-week comprehensive Summer Institute followed by face-to-face meetings during the school year, monthly virtual Google Hangouts, an online community of practice, and a follow-on Summer Institute, all of which are designed to prepare teachers for ECS course instruction, focusing both on content and instructional strategies. The PD will be provided by endorsed ECS PD facilitators and assisted by the PIs and CS graduate students; implementation support will be delivered to classroom teachers by teacher Professional Learning Communities. Additionally, recruitment and awareness activities will be carried-out to motivate high school students to take ECS, with the aim of involving 1,500 racially and ethnically diverse male and female 9th and 10th graders. The projects research agenda will advance knowledge in K-12 CS education in high-needs settings, and a rigorous evaluation plan will provide continuous guidance to the PIs to ensure that the project is on track to meet its goals and objectives.
