The latest upgrade to the football stadium at Sierra College is definitely generating some buzz around campus. Homer “Buzz” Ostrom Stadium now features a cutting edge field from AstroTurf®, which was installed in March. It’s an impressive playing surface, and one whose character is bolstered by what’s been done below the surface. The process of replacing Buzz Ostrom Stadium’s old artificial turf started underground. Valley Precision Grading, a certified AstroTurf distributor, began by remediating the underlayment with their specialized equipment. This process ensured proper drainage and level grading. That was followed by installation of a Brock Powerbase for maximum shock absorption. And finally the AstroTurf RootZone 3D3 Blend turf system was laid down. This is a high-end product that utilizes a specialized fiber blend for optimum performance, durability and game-day good looks. The signature touch for this customized playing surface at “The Buzz” is the use of green encapsulated rubber infill, which ensures a vibrant and clean surface over the life of the field. “We couldn’t be happier with the new turf installation at Buzz Ostrom Stadium,” said Lucas Moosman, Athletic Director at Sierra College. “It’s not just a replacement field, it’s a high performance upgrade that will give our student-athletes a great place to play for years to come.” With a combination of superior equipment and distinctive technique, VPG and AstroTurf are partnering to deliver unrivaled field replacement capabilities for Northern California. Some of their joint projects include the UC Berkley practice field and the revolutionary baseball field at Benedetti Diamond on the USF campus. Sierra College is a highly regarded junior college that boasts unparalleled success academically and athletically in the region. The Wolverine football team regularly plays in postseason bowl games, and the program has produced multiple All-Americans, dozens of transfers to Division I powerhouse schools, and even a few guys starring on Sundays in the NFL. About AstroTurf® For athletes and sport enthusiasts, AstroTurf® has redefined the way the game is played. The brand offers advanced, state-of-the-art, multi-sport and specialized synthetic turf systems with proprietary engineered technologies. A growing number of high schools, colleges, professional sports teams and municipalities continue to select AstroTurf-branded products for their premium quality, technical superiority, and safety.

Through a competitive process, Sierra College was awarded a $350,000 CCC Maker Grant, renewable for a second year, from the California Community College Chancellor’s Office. Sierra College was one of 24 colleges to receive a CCC Maker grant to create an inclusive makerspace community, provide internships, and develop curriculum to prepare students with innovation and entrepreneurial skills to thrive in the regional economy. As part of the CCC Maker initiative, Sierra College will be collaborating with other community colleges, sharing best practices to prepare students for the innovation economy and developing a model for creating college makerspace communities, explained Willy Duncan, Sierra College Superintendent/President. “We’ve made a conscious decision to partner with community makerspaces, such as Hacker Lab in Rocklin, Curious Forge in Grass Valley, and Truckee Roundhouse in Truckee, that are near our campuses and reflect the unique culture, interests and businesses in each part of the region,“ said Duncan. The college has hired Dominic Felipe Gutierrez as the Sierra Makerspaces Director to be the liaison between the campuses and the makerspaces. “Engaging community college students and faculty in makerspaces, and growing the maker and entrepreneurial mindset to develop creative, passionate, curious and persistent life-long learners and educators, is essential to complement existing college programs,” said Gutierrez. “The skills needed by employers are changing so rapidly that Sierra College is boldly embracing this initiative to transform what we teach and how we teach.” “In a makerspace community, members teach each other and collaborate on projects,” said Gutierrez. “Students may teach faculty and business owners skills, and they in turn may mentor students. There is a natural comradery when people are working in a shared work space and learning creative ways to use laser cutters, 3D printers and electronics, with a variety of materials such as fabric, wood and recyclables to develop new products or complete class projects.” Eric Ullrich, Co-Founder, Hacker Lab in Rocklin, Sacramento and Rancho Cordova, believes the synergy of the three makerspaces, linked through the college, will generate economic growth in the region. “Programs like Hacker Lab’s Start Up Hustle, bring together students, faculty, entrepreneurs and local businesses to develop entrepreneurial startup skills,” said Ullrich. “The CCC Maker funding will build the internal capacity of each makerspace to prepare student leaders, teach in-demand skills, develop e-commerce and physical pop-up shops, and expand business partnerships to support internships.” The Curious Forge was started in Grass Valley in 2011, with equipment for metal working, woodworking, clay work, sewing textiles, electronics and making jewelry used by over 70 creative, community minded artists, engineer and crafts people, explained Liam Ellerby, Founder. “We are in the process of moving into a new 20,000 sq. ft. space and this grant will help connect Sierra College students to hands-on skills classes and equipment that can expand learning opportunities. Our partnership with the Nevada School for the Arts will also connect our space with secondary students.” Truckee Roundhouse, located at the Truckee Airport, opened in December 2016 and offers wood, metal, ceramics, textiles and technology shops, according to Morgan Goodwin, Co-Founder and Mayor of Truckee. “We are a community-oriented shop that offers benefits for everyone,” said Goodwin. “By engaging Sierra College students and faculty, and expanding learning through this creative space, the Truckee Roundhouse will offer more STEM and arts education, blending skills and technologies to create the entrepreneurs of the future.” Contact Dominic Gutierrez at dominic(at) and follow Sierra Makerspaces on Twitter @SierraMakers, Facebook @Sierra College Makerspaces and Instagram @sierracollegemakerspaces.

Sierra College and Hacker Lab announced that Cheng Xueqin, Director of the Office of Pre-Primary Education, Anji County Department of Education, Zhejiang Province, China will present “Doing/Seeing/Thinking/Making: The Ecology of Anji Play,” on Tuesday, August 15 from 6-7:30 PM at Hacker Lab Powered by Sierra College at 4415 Granite Drive, Rocklin, CA. The community is invited. Xueqin will speak about her role leading the development of the Anji Play philosophy and social ecology over the past 16 years, explained Mary Anne Kreshka, Part-time Instructor, Human Development/Early Childhood Education, Sierra College. “This event will provide rare insight directly from the founder into the design and development of the practices, materials, environments and technology that define the Anji Play ecology,” said Kreshka. Kreshka explained that Anji Play is the focus of a unique pilot program at the Sierra College Child Development Center (CDC), administered by a collaborative partnership that includes the Nevada County Superintendent of Schools Office, Placer Community Action Council-Kidz Kount, Inc., Early Head Start/Head Start, Sierra College, and the California State Preschool Program. “Through the partnership, we are seeking to develop a model for local, interconnected and scalable educational change in close collaboration with Ms. Cheng and her team of Anji educators.” As a result of Sierra College’s partnership with Hacker Lab, the large-scale play materials were built at the mid-town Sacramento makerspace. “The system was designed in Anji and standardized by Grass Valley native and renowned designer Cas Holman, Faculty Department of Industrial Design, Rhode Island School of Design,” said Kreshk. “Hacker Lab member, Brannon Harris fabricated the play equipment for Sierra College.” Eric Ullrich, Co-Founder, Hacker Lab, believes that this is the first collaboration between a makerspace and the Anji Play collaborative system of play. “Philosophically, makerspaces and Anji Play are very compatible so it was an amazing opportunity to build the play equipment for Sierra College in our space,” said Ullrich. “We are looking forward to hosting a world renowned educator whose innovative approach encourages creating and making.” Brannon Harris spent four weeks collaborating with the design team, developing prototypes and producing the final equipment. “Working on this project, designed to provide a rich learning experience for young children, has actually provided me the richest learning opportunity I have had here at the Hacker Lab,” said Brannon. “It involved risk, reflection and real joy.” The design of Anji Play practices, materials, environments and technology develops from a primary respect for the child’s interests, thinking, experience and voice, for the connection between the child and the local community and for the complexity, depth and non-linearity of the child’s learning and development. The Anji Play approach is the focus of pilot programs at Sierra College Child Development Center, Sierra College, Grass Valley CA; Madison Public Library, Madison, WI; One City Early Learning Centers, Madison, WI and Contra Costa College, San Pablo, CA to develop a model for local, interconnected and scalable educational change.

Cinnamomum verum is used to make the spice cinnamon and has been used as a traditional Chinese herbal medicine for various applications. We evaluated the anticancer effect of 2-methoxycinnamaldehyde (2-MCA), a constituent of the bark of the plant, and its underlying molecular biomarkers associated with carcinogenesis in human hepatocellular carcinoma SK-Hep-1 cell line. The results show that 2-MCA suppressed proliferation and induced apoptosis as indicated by mitochondrial membrane potential loss, activation of caspase-3 and caspase-9, increase in the DNA content in sub-G1, and morphological characteristics of apoptosis, including blebbing of plasma membrane, nuclear condensation, fragmentation, apoptotic body formation, and long comet tail. In addition, 2-MCA also induced lysosomal vacuolation with increased volume of acidic compartments, suppressions of nuclear transcription factors NF-κB, cyclooxygenase-2, prostaglandin E2 (PGE2), and both topoisomerase I and II activities in a dose-dependent manner. Further study reveals the growth-inhibitory effect of 2-MCA was also evident in a nude mice model. Taken together, the data suggest that the growth-inhibitory effect of 2-MCA against SK-Hep-1 cells is accompanied by downregulations of NF-κB-binding activity, inflammatory responses involving cyclooxygenase-2 and PGE2, and proliferative control involving apoptosis, both topoisomerase I and II activities, together with an upregulation of lysosomal vacuolation and volume of acidic compartments. Similar effects (including all of the above-mentioned effects) were found in other tested cell lines, including human hepatocellular carcinoma Hep 3B, lung adenocarcinoma A549, squamous cell carcinoma NCI-H520, colorectal adenocarcinoma COLO 205, and T-lymphoblastic MOLT-3 (results not shown). Our data suggest that 2-MCA could be a potential agent for anticancer therapy. © 2016 Perng et al.

Variations of a demonstration in which a sheet of paper or a bead is levitated in a grazing stream as from one's breath have been published in several sources1-4. Even a massive ball can be deflected into the robust flow from a leaf blower5. The attraction is surprising because it is often quite stable and seems to conflict with the familiar transient repulsion felt from a stream's impact. © 2015 American Association of Physics Teachers.

Finite-size effects in certain critical systems can be understood as universal Casimir forces. Here, we compare the Casimir force for free, fixed, periodic, and antiperiodic boundary conditions in the exactly calculable case of the ferromagnetic Ising model in one and two dimensions. We employ a procedure which allows us to calculate the Casimir force with the aforementioned boundary conditions analytically in a transparent manner. Among other results, we find an attractive Casimir force for the case of periodic boundary conditions and a repulsive Casimir force in the antiperiodic case. © 2010 The American Physical Society.

Although diadematacean sea urchins (diadematids, aspidodiadematids, and micropygids) likely diverged sometime during the Jurassic, the lack of fossils representing this group has greatly hampered progress in understanding their evolution. No unequivocal Jurassic diademataceans have been described previously from North America. We describe a new genus and species, Sierradiadema kristini, from a single fossil from the Middle Jurassic (Callovian) Colfax sequence of the Mariposa Formation exposed in the Middle Fork American River drainage of the northern Sierra Nevada, California. The specimen, although not complete, reveals details of the spination and tooth morphology often lacking in Jurassic diademataceans, along with test architecture that yields information concerning the relative timing of important events in the origins of the diadematids in particular. We explore this evolution with a phylogenetic analysis of relevant clades with Jurassic times of divergence, finding not only that Sierradiadema n. gen. is the earliest known member of a clade containing the extant Diadematidae, but that it will stimulate ongoing discussion of the putative Jurassic origins of all the diadematacean groups. © 2014, The Paleontological Society.

We present a Monte Carlo model of the uranian rings, and compare this model to images of the system obtained with the Keck adaptive optics system in July 2004, at a wavelength of 2.2μm (from de Pater et al. (de Pater, I., Gibbard, S.G., Hammel, H.B. [2006a]. Icarus 180, 186-200)). We confirm the presence of the ζ ring, but show that this ring must extend inwards much further than previously thought, although with an optical depth much lower than that in the main ζ ring component. We further confirm dust rings between rings α-4 and β-α, as well as near the λ ring. In addition, we show that a broad sheet of faint material (τ 0∼10 -3) must be present through most of the ring region, from the α ring through the λ ring. © 2010.
