Importance of low-angle grain boundaries in YBa2Cu3O7-delta coated conductors
Over the past ten years the perception of grain boundaries in YBa2Cu3O7-δ
conductors has changed greatly. They are no longer a problem to be eliminated but an
inevitable and potentially favourable part of the material. This change has arisen as a
consequence of new manufacturing techniques which result in excellent grain alignment,
reducing the spread of grain boundary misorientation angles. At the same time there
is considerable recent evidence which indicates that the variation of properties of grain
boundaries with mismatch angle is more complex than a simple exponential decrease in critical
current. This is due to the fact that low-angle grain boundaries represent a qualitatively
different system to high angle boundaries. The time is therefore right for a targetted
review of research into low-angle YBa2Cu3O7-δ grain boundaries. This article does
not purport to be a comprehensive review of the physics of grain boundaries as found in
YBa2Cu3O7-δ in general; for a broader overview we would recommend that the reader
consult the comprehensive review of Hilgenkamp and Mannhart (Rev. Mod. Phys., 74, 485,
2002). The purpose of this article is to review the origin and properties of the low-angle grain
boundaries found in YBa2Cu3O7-δ coated conductors both individually and as a collective
system.EPSR
Suppression of vortex channeling in meandered YBa2Cu3O7-d grain boundaries
We report on the in-plane magnetic field (H) dependence of the critical
current density (Jc) in meandered and planar single grain boundaries (GBs)
isolated in YBa2Cu3O7-d (YBCO) coated conductors. The Jc(H)properties of the
planar GB are consistent with those previously seen in single GBs of YBCO films
grown on SrTiO3 bi-crystals. In the straight boundary a characteristic flux
channeling regime when H is oriented near the GB plane, associated with a
reduced Jc, is seen. The meandered GB does not show vortex channeling since it
is not possible for a sufficient length of vortex line to lie within it.Comment: Submitted to AP
Special Revelation in Cinema: The Imago Dei and Divine Transcendence in Contemporary Film
Cinema can motivate soul restoration, alter political views, and confirm or contradict personal religious beliefs. The intention of this dissertation is to show that it is plausible for the transcendent power of special revelation from God to be communicated through the medium of cinema in concert with the imago Dei in humankind. The relationship between a viewer and cinematic characters potentially becomes a visceral experience creating empathy in the viewer with the characters in the story. This relational interaction has the potential of instigating a transcendent experience as both viewer and the protagonist in a film share qualities of the imago Dei. That the cinematic experience triggers dramatic emotions in viewers is undeniable. This study proposes that narrative storytelling in cinema has the potential of functioning like the personal proclamation of the gospel and serving as a conduit by which a person may experience divine transcendence through the work of and an encounter with the Holy Spirit
Basisporium dry rot of corn
Basisporium gallarum was first found on corn from Bulgaria in 1911 by Bubak and by Arzberger in Ohio in 1913. Coniosporium gecevi Bubak is identical with Basisporium gallarum Moll. The common name of Basisporium dry rot is suggested for the disease caused by this organism.
The dry rot of corn, caused by this fungus, was very prevalent in Iowa in 1923, causing an average damage to the crop of 9.1 percent, while in a few fields from 50 to 60 percent of the ears were infected. The damage consists of moldy and light ears, reduced stand and weak plants the succeeding year.
Heavy precipitation in August and September, when the crop is maturing, favors the development of the disease. Studies to date indicate that Basisporium dry rot is markedly dependent upon excessive moisture conditions when the crop is maturing, for its destructive development.
Basisporium gallarum attacks the shanks, husks and stalks of corn. The shanks particularly are weakened and break easily. On the ears the fungus is visible at the butt and base of the kernels. The black spores of the fungus can be readily seen with the unaided eye. The kernels are affected in varying degree, some only slightly, while in others the embryo is killed.
The spores germinate poorly or not at all in water. They germinate readily in tomato or orange juice. Such juice neutralized to litmus failed to produce germination. Plant tissues in the same atmosphere with the drop cultures also stimulate germination.
This action is due to the CO2 given off by the tissues. Carbon dioxide in small amounts produces a like effect.
\u27fhe maximum, optimum and minimum temperatures for spore germination are 35° C., 25° C., and 15° C., respectively. The optimum temperature for mycelial growth is 25° C., tho good growth takes place between 20° C. and 35° C.-40° C. and 10° C. inhibit growth. Sporulation may take place between 20° C. and 35° C. The fungus readily winters over in its conidial stage.
Basisporium gallarum grows well on a wide range of media, but prefers especially media rich in nitrogenous material. On the corn kernel, the fungus destroys the embryo before it does the starchy endosperm.
Corn is most susceptible to attack during time of germination of the seed and late stages of maturity.
Inoculation of growing roots and stalks yielded negative results. Basisporium dry rot does not spread readily in cribbed corn.
In 1923 early varieties became generally infected while late varieties remained free

DISJUNCTURE AMONG CLASSIC PERIOD CULTURAL LANDSCAPES IN THE TUXTLA MOUNTAINS, SOUTHERN VERACRUZ, MEXICO
Teotihuacan was the most influential city in the Classic Mesoamerican worldsystem. Like other influential cities in the ancient world, however, Teotihuacan did not homogenously affect the various cultural landscapes that thrived in Mesoamerica during the Classic period (300-900 CE). Even where strong central Mexican influences appear outside the Basin of Mexico, the nature, extent, and strength of these influences are discontinuous over time and space. Every place within the Classic Mesoamerican landscape has a unique Teotihuacan story. In the Tuxtla Mountains of southern Veracruz, Mexico, Matacapan, located in the Catemaco Valley, drew heavily upon ideas and symbols fostered at Teotihuacan, while Totocapan, a peer political capital located in the neighboring Tepango Valley, emphasized social institutions well-entrenched within Gulf Coast cultural traditions.
Through a detailed comparison of these two river valleys, I demonstrate that each polity developed along different trajectories. By the Middle Classic (450-650 CE) each polity displayed different political, economic, and ritual institutions. While they shared an underlying material culture style, the data suggest that the regimes of both polities promoted a different ideology. These cultural divergences did not, however, cause hostilities between them. To the contrary, compositional sourcing of Coarse Orange jars indicates that they engaged in material exchanges with each other.
Agents at each settlement within the study region made unique decisions with regard to their involvement in local, regional, and macroregional interaction networks, particularly with regard to the adoption or rejection of Teotihuacan cultural elements. As a result, the Classic period Tuxtlas comprised multiple overlapping, but disjoint, landscapes of interaction. Places of human settlement were nodes on the landscape where these disjoint landscapes intersected in space and time. By examining these disjunctures, world-system studies can reveal a trend of increasing cultural diversity that parallels the better-theorized trend of homogenization emphasized by core-periphery models. In this dissertation, I take the initial steps toward developing an archaeology of disjuncture that examines the cultural variability that develops where groups across the landscape employ different strategies of interaction within the world-system
Rising Scholars: Narratives of Formerly Incarcerated/System-Impacted Community College Students in an On-Campus Support Program
This study uplifted the stories of formerly incarcerated and/or system-impacted students attending a California community college (i.e., “Rising Scholars”) to provide qualitative context to a growing literature following the state’s promotion of support programs at the University of California (UC), California State University (CSU), and California Community Colleges (CCC) systems. This study interviewed six formerly incarcerated/system impacted Rising Scholars using a narrative inquiry methodology with a theoretical framework of Critical Race Theory (CRT) and Desistance theory to inquire about their educational experiences before and during their enrollment at an urban California community college with reentry support. Key themes in the interviews include trauma in early educational experiences, dropping out of college, the gendered experiences of formerly incarcerated women, the role of pregnancy and parenthood as a turning point, and authentic care expressed by the support staff. The narratives of the participants are offered as a counter-narrative to the quantitative neoliberal practice of justifying reentry programs based solely on reductions in recidivism rates.
Recommendations include increasing trauma-informed pedagogy in TK-12 and Postsecondary education, recruiting and educating more allies for Rising Scholars on campus, ensuring that campus reentry support programs fully meet the needs of female Rising Scholars, and uplifting successes and scholarship by Rising Scholars to build lasting structural support for the Rising Scholars Network
