However, in 2004, Maher concluded that " Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered " when treating lower back pain with an evidence-based approach.

However, it was discovered during test runs that the proposed motors and wheels would fail to provide adequate traction under some conditions, for example, when ice appeared on the rail.

However, in low-traction conditions on a soft surface, the same mechanism could allow one wheel to slip, further reducing traction.

However, by the end of the 1960s it was certainly clear that Greenberg's stipulations for art to continue within the confines of each medium and to exclude external subject matter no longer held traction.

However, the Dutch soon found theirs unsatisfactory and replaced both the diesel engines and the electric traction motors in the early 1950s.

However, many low and medium performance bicycle tyres have substantial tread depth, because the bicycles are designed with off-road excursions in mind, in dirt, gravel, or sand the tread provides significantly improved traction.

However the massive power cannot be converted to motion at low speeds due to traction loss and the usual figure is 2 seconds to reach.

However, WJXX failed to gain significant traction in the market ; in addition to lingering confusion from the early announcement of WBSG being the ABC affiliate for Jacksonville and the subsequent early launch, the station never had full signal parity with VHF competitors WJXT ( channel 4 ; then a CBS affiliate ) and WTLV, even with the help from WBSG.

However, much larger universal motors were used, fed by special low-frequency traction power networks to avoid problems with commutation under heavy and varying loads.

However, railway traction current systems are two-pole AC systems, so traction lines are designed for two conductors ( or multiples of two, usually four, eight, or twelve ).

However, a few seconds after stopping, the traction power supply tripped out, stranding the train.

However, they also share characteristics with mountain bicycles in that they utilize knobby tread tires for traction, and cantilever style brakes for clearance needed due to muddy conditions.

However, the car that made the additional pit stop will run faster on the race track than cars that did not make the stop, both because it can carry a smaller amount ( and thus lower weight ) of fuel, and will also have less wear on its tires, providing more traction and allowing higher speeds in the corners.

However, most railroads were assured of the reliability of the GE Model 752DC traction motor, and began to place orders for U30Cs starting in 1966.

However, the BTC were not convinced that the future of diesel traction lay down the hydraulic transmission path of the Western Region, and began looking at various diesel-electric designs.

However, electric motor traction had been considered all along, and much engineering progress had been made since the tunnel's construction had begun in 1886.

However the 365s retain the original 750 volt DC bus, meaning that when on 25 kV overhead lines the current is collected as AC, rectified to DC for the onboard systems, and then inverted back to AC for the 3-phase traction motors.

However, it failed to gain traction.

However, after gaining the support of Senators Strom Thurmond of South Carolina, and Dennis DeConcini of Arizona, congressional support for a ban on import or possession of ballistic knives quickly gained traction.

However, it was not of innocence in general that I was speaking, but of perhaps the frailest and surely the least important side of it which is innocence in romantic love.

However, in this case as elsewhere it was necessary to arrive at a single standard to be applied to all situations, representing an averaging of conditions, and thus to fix particular points in time which would be considered the dividing points between daytime and nighttime conditions.

However, the Attorney General of California, at the request of the Secretary of Labor, sought to have the jurisdiction over the issue removed to the Federal District Court, on grounds that it was predominantly a Federal issue since the validity of the Secretary's Regulation was being challenged.
