Empirical formula applied to the lowest excitation energies of the natural parity odd multipole states in even-even nuclei

We applied our recently proposed empirical formula, a formula quite successful in describing essential trends of the lowest excitation energies of the natural parity even multipole states, to the lowest excitation energies of the natural parity odd multipole states in even-even nuclei throughout the entire periodic table. Even though the systematic behavior of the lowest excitation energies of odd multipole states is quite different from those of even multipole states, we have shown that the same empirical formula also holds reasonably well for the odd multipole states with the exception of a few certain instances.Comment: 23 pages, 11 figure

PREVENTATIVE AND THERAPEUTIC EFFECTS OF BMSC EXOSOME ON PERIODONTAL DISEASE

Periodontitis is an inflammatory disease caused by the imbalance between host immune response and bacterial infection. Strategies to manage the uncontrolled, excessive immune response and to promote tissue healing are in great demand. Therapies based on mesenchymal stem cells (MSCs) are promising and the clinical effects of MSCs are largely mediated by their secretome, especially exosomes. Previously, we isolated and purified exosomes secreted by human bone marrow mesenchymal stem cells (hBMSC). These exosomes have proliferative, chemotactic, anti-inflammatory and anti-osteoclastic function in vitro. In this study, we had two hypotheses: 1) hBMSC exosomes would prevent periodontal inflammation and alveolar bone loss with immunomodulatory function; 2) hBMSC exosomes would enhance 2 periodontal tissue regeneration. To test these hypotheses, we used a rodent ligature-induced experimental periodontitis model. In the preventative experiment, rats were treated with hBMSC exosomes concurrently with ligature placement. In the regenerative experiment, rats were treated with hBMSC exosomes for 3 weeks and 6 weeks after the experimental periodontitis was induced. Our results show that, in the preventive study, hBMSC exosome treatment led to less disease progression as evidenced by increased alveolar bone volume, decreased linear bone loss, and less lymphocyte infiltration in the subepithelial area. However, through micro-CT and gene expression analyses, no significant differences were seen between the exosome treatment and control in the regenerative study at both time points. In summary, hBMSC exosomes can ameliorate the development of periodontitis via an immunomodulatory effect. However, more studies are needed in the future to investigate their regenerative potential in periodontal tissues

Domain model as problem-oriented architecture application for mobile applications

Domain modeling is an activity that develops a generic model of a family of systems. It has been considered as one of the significant activities in systematic reuse. Frameworks can be used for allowing the design layers, permitting the construction of an intricate structures and reusing development information. In this paper, we will discuss the domain modeling supporting tool that extracts candidate domain model objects to construct frameworks from domain descriptions in a typical text form

Development of smart talking plant with voice recognition function

Plants can tell us what is affecting them with the electrical signals they emit with the help of (Internet of things) IoT.In such ways that is your plant thriving under current light levels? Is your plant thirsty? Or even satisfy with your care? The goal this project is to encourage a happy relationship between plants and people as a lot of people are afraid of plants. Not they are not green handed. The idea of taking good care is a responsibility. This makes it possible for them to have a plant in their lives. As Arduino came into the picture in bringing a better solution for plant care, we proposed an ideal smart plant based on an existing system that will add more features to it to make an all in one architecture. We also presented some useful projects related to this for comparison and future references
