    UNC Chapel-Hill has great amount of gym facility and fitness group class services which are free to all students. However, students do have trouble in choosing the most suitable fitness group class due to many options and lacking in knowledge. For example, students who are new to fitness aren’t very familiar with it. They are lacking in information about what kind of activity the class is doing as well as the best suitable class for them. Some classes are targeted to Intermediate fitness enthusiasts and may not be suitable for beginners, while some classes are entry-level courses for beginners and experienced fitness lovers may find them boring. So it is definitely helpful if the website has detailed description of the class info, including the teacher, targeted people and brief information about the activity. For certain students, they love some teacher who have their unique teaching methods.Master of Science in Information Scienc

    Synergistic reinforcement, crystallization and degradation of PVA-graphene-clay composites

    Full text link
     Initially, synergistic reinforcement PVA composite has been successfully developed by using graphene and MMT. Furthermore, new knowledge of the crystallization mechanism of the PVA and PVA composites was revealed. Finally, Isothermal degradation kinetics models and mechanism of the as-prepared composites were also proposed

    Damage characteristics and constitutive modeling of the 2D C/SiC composite: Part I – Experiment and analysis

    AbstractThis paper reports an experimental investigation on the macroscopic mechanical behaviors and damage mechanisms of the plain-woven (2D) C/SiC composite under in-plane on- and off-axis loading conditions. Specimens with 15°, 30°, and 45° off-axis angles were prepared and tested under monotonic and incremental cyclic tension and compression loads. The obtained results were compared with those of uniaxial tension, compression, and shear specimens. The relationships between the damage modes and the stress state were analyzed based on scanning electronic microscopy (SEM) observations and acoustic emission (AE) data. The test results reveal the remarkable axial anisotropy and unilateral behavior of the material. The off-axis tension test results show that the material is fiber-dominant and the evolution rate of damage and inelastic strain is accelerated under the corresponding combined biaxial tension and shear loads. Due to the damage impediment effect of compression stress, compression specimens show higher mechanical properties and lower damage evolution rates than tension specimens with the same off-axis angle. Under cyclic tension–compression loadings, both on-axis and off-axis specimens exhibit progressive damage deactivation behaviors in the compression range, but with different deactivation rates

    SDSS-IV MaNGA: The Roles of AGNs and Dynamical Processes in Star Formation Quenching in Nearby Disk Galaxies

    Full text link
    We study how star formation (SF) is quenched in low-redshift disk galaxies with integral-field spectroscopy. We select 131 face-on spiral galaxies with stellar mass greater than 3×1010M⊙\rm 3\times10^{10}M_\odot, and with spatially resolved spectrum from MaNGA DR13. We subdivide the sample into four groups based on the offset of their global specific star formation rate (SFR) from the star-forming main sequence and stack the radial profiles of stellar mass and SFR. By comparing the stacked profiles of quiescent and star-forming disk galaxies, we find that the decrease of the global SFR is caused by the suppression of SF at all radii, but with a more significant drop from the center to the outer regions following an inside-out pattern. As the global specific SFR decreases, the central stellar mass, the fraction of disk galaxies hosting stellar bars, and active galactic nuclei (AGNs; including both LINERs and Seyferts) all increase, indicating dynamical processes and AGN feedback are possible contributors to the inside-out quenching of SF in the local universe. However, if we include only Seyferts, or AGNs with EW(Hα)>3A˚{\rm EW(H\alpha)>3\AA}, the increasing trend of AGN fraction with decreasing global sSFR disappears. Therefore, if AGN feedback is contributing to quenching, we suspect that it operates in the low-luminosity AGN mode, as indicated by the increasing large bulge mass of the more passive disk galaxies.Comment: 12 pages, 7 figures, published in ApJ, typos corrected, references update

    The objective of this project is to create an online enterprise resource planning application which allows various manufacturing companies to manage their day to day operations and plan resources accordingly. This is important part of business systems which supports the concept of continuous improvement by giving organizations the resources needed to reduce waste. The problem which most manufacturing facilities encounter is poor communication between various function such as production and master production schedulers. For example, on day shift the production team is scheduled to produce two thousand xy widgets and after completing the order then change over to xyz widgets. What if day shift production encounter significant downtime and run behind schedule? This places production behind schedule and can also influence the way raw material is ordered. Therefore, the goal of this project is to create an application which can be leverage by all functions to make decisions as well as identify performance gaps. The enterprise resource planning software will be a newly implemented software replacing a paper system used to reconcile production resources and cost at the end of each shift. The system is scheduled to be available for use by production supervisors by April 2016

    Studies on the properties and the thermal decomposition kinetics of natural rubber prepared with calcium chloride

    Full text link
    To evaluate calcium chloride coagulation technology, two kinds of raw natural rubber samples were produced by calcium chloride and acetic acid respectively. Plasticity retention index (PRI), thermal degradation process, thermal degradation kinetics and differential thermal analysis of two samples studied. Furthermore, thermal degradation activation energy, pre-exponential factor and rate constant were calculated. The results show that natural rubber produced by calcium chloride possesses good mechanical property and poor thermo-stability in comparison to natural rubber produced by acetic acid.<br /

    According to the mobile storage characteristic of electric vehicles, an emergency power supply model about the electric vehicles is presented through analyzing its storage characteristic. The model can ensure important consumer loss minimization during power failure or emergency and can make electric vehicles cost minimization about running, scheduling, and vindicating. In view of the random dispersion feature in one area, an emergency power supply scheme using the electric vehicles is designed based on the K-means algorithm. The purpose is to improve the electric vehicles initiative gathering ability and reduce the electric vehicles gathering time. The study can reduce the number of other emergency power supply equipment and improve the urban electricity reliability

    Prediction of the anti-inflammatory effects of bioactive components of a Hippocampus species-based TCM formulation on chronic kidney disease using network pharmacology

    Get PDF
    Purpose: To systematically study and predict the therapeutic targets and signaling pathways of Hippocampus (HPC) against chronic kidney disease (CKD) using network pharmacology.Methods: By combining database mining, literature searching, screening of disease targets, and network construction, the effects of various components of HPC on several proteins related to CKD were predicted and the active compounds were screened. Genes related to the selected compounds were linked using the SEA database. The correlation between CKD and genes was determined using OMIM, DisGenNet, and GeneCards databases. Pathway-enrichment analyses of overlapping genes were undertaken using online databases.Results: A total of 144 compounds in HPC were identified. Analyses of clusters suggest that the active components of HPC and the target genes against the inflammation caused by CKD were due to 10 compounds and 25 genes. Metascape results showed that these HPC targets are related to CKD inflammation.Conclusion: The active components of HPC and the target genes against CKD inflammation are involved in multiple signaling pathways, such as AGE-RAGE, TLR, TNF, and NF-κB. This work provides scientific evidence to support the clinical use of HPC against CKD
