Development of juvenile culture techniques and testing of potential biomarkers of environmental stress in freshwater mussels (Bivalvia: Unionidae)
… juvenile mussels, confined in small dishes, into oval troughs supplied with untreated river water. Two of three years produced acceptable survival rates of 27% and 19% to an age of 90 days or greater. The third year yielded very low survival rates of less than 3%, demonstrating that failures in …

Quantization of spin waves in ferromagnetic Ni80Fe20 nanoring
Regular arrays of oval-shaped permalloy nanorings have been fabricated using deep ultraviolet lithography and their spin dynamicsmeasured by Brillouin light scattering with the magnetic field applied along long (easy) axes of the rings. The dispersionless behavior of the spin wave modes observed …

Estudo comparado das sensilas dos flagelômeros antenais de diferentes castas e sexos da formiga cortadeira Acromyrmex subterraneus subterraneus Forel, 1893 (Hymenoptera: Formicidae)
… uma depressão na cutícula, contendo uma abertura oval ao centro. As Ap são morfologicamente semelhantes às Co, diferenciando-se apenas pela menor abertura oval ao centro. De forma geral, os mesmos tipos de sensilas foram encontrados nas fêmeas (máximas, mínimas, rainhas) e nos machos de A. …

An application of Value Stream Mapping to reduce lead time and WIP in a make-to-order manufacturing line
… to identify the bottleneck processes: fit up (oval), full welding, and pressure testing. Assembly cell concept, workload balancing and FIFO lanes were proposed countermeasures or improvements to address the capacity shortfall. A decrease of 27% in manufacturing lead time was projected if these …

High-Latitude Ionospheric Irregularities Characterized Through Machine Learning Methods
… from electron precipitation in the auroral oval and ExB drifts in the polar cap. Using Machine Learning tools, the study aims to distinguish between different scintillation signatures and link them to their sources, improving our ability to detect and characterize these events. Using …

Hyperovals, Laguerre planes and hemisystems - an approach via symmetry
… problems in the area. We first look at hyperovals in finite Desarguesian projective planes. In the last 25 years a number of infinite families have been constructed. The area has seen a lot of activity, motivated by links with flocks, generalized quadrangles, and Laguerre planes, amongst …

Honor, not sainthood : interpreting scandals and personal flaws in presidential homes, museums and libraries.
… of the different kinds of men who occupied the Oval Office. In many cases, these men have been put on a high pedestal by staff who operate the homes, museums and libraries which tell the story of the presidents. Sometimes the stories that are told at these places have left out personal struggles …

Characterization of genetically distinct neuronal subtypes in the lateral habenula using Cre mouse lines
… These have been designated as the HbX, lateral, oval/medial, and marginal subregions of the LHb. Each subregion is marked by non-overlapping genes. Cre mouse lines can be used as a tool to target these genes and thus manipulate these subtypes. This project utilizes fluorescence in situ …

Human kinematic responses to walking and riding camels and horses.
… sagittal plane, pelvic trajectories display an oval pattern during walking and camel-riding and a more diagonal pattern during horse riding. This study shows that many features of human pelvic kinematics during walking can be reproduced when riding on a horse or camel. To date, this is the first …

Visualization of neuronal geometry in ventral nerve cord ganglia of Acheta domesticus
… ganglion of the thorax or abdomen is usually an oval mass of nerve tissue, continuous with the interganglionic connectives (Fig. A). Two or three principal lateral nerves extend from its sides. The ganglion is encased in a nucleated sheath, the neurilemma, which forms a continuous covering over …

Three Dimensional CT based Virtual Patellar Resection in Female Patients undergoing Total Knee Replacement
… TM gave a thicker resected patella, and a less oval cut surface shape which gives better coverage for a domed prosthesis. Both methods however, gave a symmetric resection both superio-inferiorly as well as medio-laterally. Conclusions: Though TM appears statistically better with respect to the …
