OBJECTIVE To anatomically evaluate the femoral origin and tibial insertion of the anteromedial and posterolateral bands of the anterior cruciate ligament. METHODS We studied eight cadaver knees as for the following: in the femur, distance from the center of the anteromedial band to the deep cartilage and the ceiling; also in the femur, distance from the center of the posterolateral band to th...

purpose: to determine the normal values of bony inter- and intra-orbital distances in an iranian adult population by orbital ct scan. methods: the study was conducted on all adults who were referred to farabi eye hospital from march 2003 to june 2005 for ct scan ordered for complaints unrelated to craniofacial or orbital abnormalities. patients were excluded in the presence of any pathology of ...

Kalimantan is an island surrounded by tropical rain forests and has hot humid weather because it crossed the equator. The affects human working climate in exchange of air room, for example laboratory. This study objective was to know amount per hour at Samarinda Occupational Safety Health Center. tools used were TESTO 425 anemometer, a digital meter, thermohygrometer, manometer, laptop. chamber...

A slow cortical wave of high calcium accompanies the elongation of cleavage furrows in medaka fish eggs as well as in Xenopus eggs. We explored the role of such waves by injecting calcium buffers into Xenopus eggs at various times before and during first and second cleavage. Injection earlier than about 15 minutes before first cleavage normally starts delays it for hours. Injection between abou...

We have formulated the momentum equation for sectorial line driven winds from rotating stars including: (a) the oblateness of the star, (b) gravity darkening (von Zeipel effect), (c) conservation of angular momentum, (d) line driving specified by the force multiplier parameters (k, α, δ), (e) finite disk correction factors for an oblate star with gravity darkening for both the continuum and the...

Ocean prediction systems are now able to analyse and predict temperature, salinity and velocity structures within the ocean by assimilating measurements of the ocean’s temperature and salinity into physically based ocean models. Data assimilation combines current estimates of state variables, such as temperature and salinity, from a computational model with measurements of the ocean and atmosph...

We consider streamline patterns associated with single and double von Kármán point vortex streets on the surface of a nonrotating sphere, with and without pole vortices. The full family of streamline patterns are identified and the topological bifurcations from one pattern to another are depicted as a function of latitude and pole strength. The process involves first finding appropriate vortex ...

We have studied microtubule behavior in late anaphase and telophase spindles of PtK1 cells, using fluoresceinated tubulin (DTAF-tubulin), microinjection, and laser microbeam photobleaching. We present the results of two novel tests which add to the evidence that DTAF-tubulin closely mimics the behavior of native tubulin in vivo. (a) Microinjected DTAF-tubulin was as effective as injected native...

The authors examined whether absolute and relative judgments about global-scale locations and distances were generated from common representations. At the end of a 10-week class on the regional geography of the United States, participants estimated the latitudes of 16 North American cities and all possible pairwise distances between them. Although participants were relative experts, their latit...
