Rotational instability of the knee may persist after anterior cruciate ligament (ACL) reconstruction, which may be due to insufficiency of anterolateral stabilizing structures. However, no reliable diagnostic tool or physical examination test is available for identifying patients with anterolateral rotatory instability (ALRI). As shown in cadaveric studies, static internal rotation of the knee is increased in higher flexion angles of the knee after severing the anterolateral structures. This might also be the case in patients with an ACL-deficient knee and concomitant damage to the anterolateral structures. The objective of this study is to assess anterolateral rotatory instability of the knee during physical examination with a tibial internal rotation test. ACL-injured knees of 52 patients were examined by two examiners and side-to-side differences were compared. Both lower legs were internally rotated by applying manual internal rotation torque to both feet in prone position with the knees in 30°, 60
FUEL CELL SYSTEM AND METHOD OF CONTROLLING ROTATION SPEED OF COMPRESSOR - Even when the atmospheric pressure is lowered, a sufficient amount of oxidant gas is supplied to a fuel cell without causing any failure in a compressor. A control unit judges whether or not both the following conditions are satisfied: the accelerator opening degree detected by an accelerator opening degree sensor is equal to or larger than a predetermined opening degree; and the state where the atmospheric pressure detected by a pressure sensor is equal to or lower than a predetermined pressure value has been maintained for a predetermined time period or longer. If the judgment result is positive, the control unit changes the maximum rotation speed permitted in the compressor from a normal maximum rotation speed to an increased maximum rotation speed. The control unit then judges whether or not a predetermined time period has elapsed from when the maximum rotation speed was changed to the increased maximum rotation speed, ...

This is a group of three synovial joints that occur between the first two cervical vertebrae, the atlas and the axis. The altlanto-axial joint complex consists of two somewhat planar lateral joints between the articular facets of the lateral masses of the respective bones, and a median pivot joint where the dens of the axis fits into a fibro-osseous tunnel formed by the anterior arch and transverse ligament of the atlas. The principal motion at this joint is rotational movement in the transverse plane, as if one is shaking their head to say "no." In addition to the transverse ligament mentioned above, the fibrous capsules of the lateral joints and the alar ligaments, which attach between the dens and the medial aspect of the occipital condyles, are primarily responsible for limiting the rotational movements of the joint ...

A drive mechanism for a medication delivery device is presented having a housing, a rotation member that rotates in a first direction with respect to the housing during setting of a dose of a medication and rotates in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction. The device also has a piston rod that is displaced in a distal direction with respect to the housing for delivering the dose, a drive member which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose.
A hand operated power tool comprising a housing with a motor and a working element performing an actuating movement if the tool is actuated. The motor is adapted to actuate a tool shaft in order to make it perform a rotational movement. A carrier element is functionally located between the tool shaft actuated by the motor and the working element for translating the rotational movement of the tool shaft into the actuating movement of the working element. In order to provide for a power tool, which allows perfect working of a workpiece with different types of actuating movements and/or working elements, it is suggested that the working element and the carrier element make part of a functional unit constituting a unit separate of the rest of the tool, wherein the functional unit is detachably fixed to the rest of the tool, in particular to the tool shaft.
Distance limiting self-retractable lifeline - A self-retractable lifeline ("SRL") having the combination of an active fall arrest braking system and a passive restraint distance limiting mechanism that allows a user to pretension and preset the distance that its cable is capable of paying out. The SRLs cable limiting mechanism includes a pretension assembly, which may include a pair of aligned plates and an actuator that temporarily mobilizes an arbor when the lever is opened. The arbor is affixed to the SRL housing and to an interior of a power spring that rewinds the cable back into the housing when the cable is paid out. The other end of the arbor is in a mechanical relationship to one of the aligned plates that prohibits rotational movement of the arbor when the aligned plates are engaged but allows rotational movement of the arbor when the aligned plates are temporarily disengaged. When pretensioning of the power spring is desired, the actuator is activated and a tension is applied onto at ...

We investigated the perception of self-rotation using constant-velocity chair rotations. Subjects signalled self motion during three independent tasks (1) by pushing a button when rotation was first sensed, when velocity reached a peak, when velocity began to decrease, and when velocity reached zero, (2) by rotating a disc to match the perceived motion of the body, or (3) by changing the static position of the dial such that a bigger change in its position correlated with a larger perceived velocity. All three tasks gave a consistent quantitative measure of perceived angular velocity. We found a delay in the time at which peak velocity of self-rotation was perceived (2-5 s) relative to the beginning or to the end of chair rotation. In addition the decay of the perception of self-rotation was preceded by a sensed constant-velocity interval or plateau (9-14 s). This delay in the rise of self-motion perception, and the plateau for the maximum perceived velocity, contrasts with the rapid rise and ...

The last few weeks I have been on rotation with Dr. Hae Mi Choe at the East Ann Arbor Ambulatory Care Clinic. It has been a great experience in part because I have never experienced amb care before but also because I have been able to accompany Dr. Choe on many of her administrative meetings. I have gained a greater understanding of how amb care clinics fit into the health-system. They serve an integral role in patient care as patients transition from hospital to home. The University of Michigan has a great model where pharmacists pair with physicians to help manage medication therapy on an outpatient basis. For example, we had a patient who was recently diagnosed with type 2 diabetes and her primary care physician sent her to the pharmacist to learn about her medications and glucometers. I spent about 30 minutes with the patient teaching her and her daughter how to measure blood sugar levels and she was very grateful for our time together. We will be following up with the patient over the next ...

Minimizing retinal image slip during locomotion is essential to maintain visual acuity (Angelaki and Hess, 2005; Angelaki and Cullen, 2008). For optimal performance, however, it is necessary that the spatiotemporal profile of gaze-stabilizing eye movements matches the organization and dynamics of the particular locomotory modality used. Although locomotion of terrestrial tetrapods with flexible necks generally requires relatively complex 3D eye movements to stabilize retinal images, the undulatory tail-based swimming of most aquatic vertebrates, such as larval Xenopus (Hoff and Wassersug, 1986; Azizi et al., 2007), necessitates only relatively simple paired (conjugate) ocular movements to counteract head rotational movements that are mainly in the horizontal plane. Indeed, such an eye motion profile has been recently observed during swimming in Xenopus tadpoles (Lambert et al., 2009, 2012), consistent with alternate burst discharge elicited in bilateral synergistic pairs of MR and LR motor ...
The connector pin assembly releasably retains telescoped excavating support and wear members in their telescoped relationship. The connector pin assembly is removably received in aligned connector openings in the members. A body portion of the assembly blocks removal of the wear member from the support member, and a lock member portion of the assembly is rotatable relative to the body, toward and away from a locking orientation, to releasably lock the body within the connector openings. A resilient sleeve having non-circular interior and exterior surfaces with rounded corners is non-slippably disposed over a rotatable shaft of the lock member in order to slidingly and deformably engage a non-circular shaped interior cavity of the body that rotatably receives shaft and sleeve of the lock member. The sleeve yieldingly resists rotational movement of the lock member away from a locking orientation.
Visual and non-visual cues, both static and dynamic, affect perception of body orientation relative to gravity. Prior research has investigated the relative influence of static orientation and dynamic rotation vestibular signals (from the otoliths and canals, respectively) on perceived body roll. We used a cue-conflict paradigm to directly compare the influence of static orientation and dynamic rotation visual cues. Vestibular stimulation was provided by rolling the subject. Visual stimulation was provided by a stereo display attached to the rolling device. Subjects set a visible rod to earth-vertical after being rolled to the target angle. In static conditions, the visual scene appeared only when the target angle was reached. In dynamic conditions, a rotating scene was visible throughout. The speed of the visual rotation was varied relative to the speed of the body rotation. Four visual scenes were used: 1) dynamic room scene; 2) static room; 3) static cube; 4) dynamic random-dot cloud. ...

In an electronically commutated motor (M), rotor position signals are generated by means of a galvanomagnetic rotor position sensor (40). A timer (CNT_HL) brings about an advanced commutation which occurs only once the motor has reached a specific rotation speed, and whose magnitude is a function of the rotation speed.
Different modalities have been used to describe the rotational motion of the ventricles of the heart and studies have indicated LV twist to be an additional integral component in LV function. So far, only amplitudes and timings of rotation have been reported, whereas no method is available to fully describe the rotation pattern of the ventricles. The object of the present application is to achieve a system that presents a novel way to quantify and visualize the ventricular rotation pattern of the heart. We present a novel method that assesses and describes the rotation pattern by calculating the rotation axis of the ventricle. Non- invasive image acquisition is required to collect rotation values from different positions of the myocardium. Thereafter, a kinematic model of a ventricle is constructed to determine the rotation planes at different levels of the heart. The motion of the rotation planes are visualized by plotting the normal vectors of the planes over time, i.e. the rotation axis of ...
Regulation of the direction of flagellar rotation is central to the mechanism of bacterial chemotaxis. The transitions between counterclockwise and clockwise rotation are controlled by a switch complex composed of three proteins (FliG, FliM, and FliN) and located at the base of the flagellar motor. The mechanism of function of the switch is unknown. Here we demonstrate that the diffusible clockwise-signal molecule, the CheY protein, binds to the switch, that the primary docking site is FliM, that the extent of CheY binding to FliM is dependent upon the phosphorylation level of CheY, and that it is unaffected by the other two switch proteins. This study provides a biochemical demonstration of binding of a signal molecule to the bacterial switch and demonstrates directly that phosphorylation regulates the activity of this molecule ...

I should add that your expression in #1 represents a standing wave CP (sum of two counter-propagating CP waves of opposite CP polarization) not propagating one. For a single propagating CP wave, the sin(kz) term is absent and the cos(ωt), cos(ωt-π/2) arguments are replaced with cos(ωt-kz-θ), cos(ωt-π/2-kz-θ) respectively, with θ determined by the given t=0 temporal phase conditions at z=0. That may represent a LCP wave (left circularly polarized) - counterclockwise rotation of field as viewed along propagation axis with wave receding. For a RCP wave, an extra phase angle of π is added to either one, but not both, of the above arguments for cos. Convention for handedness can vary, but I believe above is the more standard one ...
The four limb buds begin to develop in the fifth week of gestation with all four having a parallel axis. The great toes initially develop in a preaxial position, and with medial rotation are seated at the midline by week seven. Intrauterine molding continues, with variable positioning of the feet, internal rotation of the tibia, and external rotation of the hip. This can lead newborns to have common deformities related to these positions. The lower extremities continue to externally rotate in the postnatal period until around age 8-10 years when adult values are typically reached. On average, femoral anteversion will decrease about 25 degrees to a value of 15 degrees, with the tibia externally rotating 15 degrees (Staheli, 1985 ...
The MS05/MSE05 from Poclain Hydraulics benefits from a new valving, the design of which has been optimized to considerably reduce pressure drops (a 50% reduction in pressure drops has been recorded compared to the standard MS05/MSE05 model). It has also been fitted with a closed and more robust cover. The MS high-flow range can withstand the most heavy-duty of workloads and the most extreme environmental conditions. The motors can reach speeds that are 50% higher without any additional pressure drops. As such, they can ensure better machine productivity. As it is now available in symmetrical two-displacement, the MS05/MSE05 no longer has a preferred rotation direction and promotes a maximum speed whatever the machines direction of travel. This characteristic is particularly useful in rail/road applications. This option also means that only a single reference needs to be used for the left and right motors of a vehicle, and thus simplifies the chains of supply and assembly. ...

A group with researchers at the Technical University of Munich (TUM) are the first to plot changes in the Earths axis through laboratory measurements. To do this, they constructed the worlds most stable ring laser in an underground lab and used it to determine changes in the Earths rotation. Previously, scientists were only able to track shifts in the polar axis indirectly by monitoring fixed objects in space. Capturing the tilt of the Earths axis and its rotational velocity is crucial for precise positional information on Earth - and thus for the accurate functioning of modern navigation systems, for instance. The scientists work has been recognized an Exceptional Research Spotlight by the American Physical Society.
We conducted high-dispersion spectroscopic observations of 50 superflare stars with Subaru High Dispersion Spectrograph (HDS), and measured the stellar parameters of them. These 50 targets were selected from the solar-type (G-type main sequence) superflare stars that we had discovered from the Kepler photometric data. As a result of these spectroscopic observations, we found that more than half (34) of our 50 targets have no evidence of binary systems. We then estimated the effective temperature (Teff), surface gravity (log g), metallicity ([Fe/H]), and projected rotational velocity (vsin i) of these 34 superflare stars on the basis of our spectroscopic data. The accuracy of our estimations is higher than that of the Kepler Input Catalog (KIC) values, and the differences between our values and KIC values [(DeltaTeff)rms ˜ 219 K, (Deltalog g)rms ˜ 0.37 dex, and (Delta[Fe/H])rms ˜ 0.46 dex] are comparable to the large uncertainties and systematic differences of KIC values reported by the ...
In computed tomography (CT), projection images of the sample are acquired over an angular range between 180 to 360 degrees around a rotation axis. A special case of CT is that of limited-angle CT, where some of the rotation angles are inaccessible, leading to artefacts in the reconstrucion because of missing information. The case of flat samples is considered, where the projection angles that are close to the sample surface are either i) completely unavailable or ii) very noisy due to the limited transmission at these angles. Computed laminography (CL) is an imaging technique especially suited for flat samples. CL is a generalization of CT that uses a rotation axis tilted by less than 90 degrees with respect to the incident beam. Thus CL avoids using projections from angles closest to the sample surface. We make a quantitative comparison of the imaging artefacts between CL and limited-angle CT for the case of a parallel-beam geometry. Both experimental and simulated images are used to ...

When a user wants to switch between IK and FK, they dont really want to destroy the current IK solution. What they really want to do is rotate the IK chain from the selected bones base to the solver, on a local axis defined by the line between the selected bones base and that same solver. So heres how you do it: you dont need to generate true FK keyframes. You also dont use the IK solvers influence to do it. Each bone in an IK chain has a button next to its name in the Edit Buttons, called FK Move. If that button is clicked, rotations on that bone also move the IK target, as though it were the (non-IK) child of the bone. You can download this simple example .blend file showing three armatures here:http://www.harkyman.com/IKFKDemo.blend The first is freeform IK, the second is IK with the IK target as the child of the shoulder bone, the third is IK with the IK target as the child of the forearms bone. So, when doing an "FK Move" rotation on an IK chain, youre generating rotation keys for ...

These numbers will let you do apple-with-apples comparisons of disks. Beware that they will differ on different-size models of the same disk; typically, bigger disks have slower seek times.. Now what does it all mean? Bandwidth first: the `media transfer rate is how much data you can, under ideal conditions, get off the disk per second. This is a function mostly of rotation speed; the faster the disk rotates, the more data passes under the heads per time unit. This constrains the sustained bandwidth of this disk.. More interestingly, your effective latency is the sum of typical seek time and rotational latency. So for a disk with 8.5ms seek time and 4ms rotational latency, you can expect to spend about 12.5ms between the moment the disk `wants to read your data and the moment when it actually starts reading it. This is the one number you are trying to make small. Thus, youre looking for a disk with low seek times and high rotation (RPM) rates.. For comparison purposes, the first hard drive I ...

As of commit 68743f9b8a95b7fa8ddc582cec507b6ac7788789 the rotation support is disabled unless you export the QGIS_ENABLE_CANVAS_ROTATION variable in the environment (with any value). Hopefully this will help focusing on any regression that may be introduced in an attempt to enhance rotation support. Those willing to use or test rotation can still do so via the env variable and report issues in the new feature not yet polished enough category.

A device for use in the mixing of fluids, e.g. the gasification of liquids, comprises an elongate member including an internal passage; and, mounted on the elongate member via radials arms, one or more venturi members each having a convergent-divergent duct whose axis is substantially tangential to the elongate member, and in which the neck of the duct has an opening in communication, via passages in the radial, with the internal passage. On rotation of the device, reduced pressure in the duct neck draws fluid down the shaft of the elongate member.
