Leadership and Sprituality

With a combined wealth of experience, the authors explore the connection between leadership and spirituality. Reflecting upon their own respective experiences and relevant literature, there appears to be a certain conclusion that spirituality must be imbued in every leader. Whether that spirituality is faith-based or simply inspired by servant-orientation, it is this type of leadership that must be advocated as a way to ensure that all leaders are driven by a moral compass

Apparatus for precision focussing and positioning of a beam waist on a target

The invention relates to optical focussing apparatus and, more particularly, to optical apparatus for focussing a highly collimated Gaussian beam which provides independent and fine control over the focus waist diameter, the focus position both along the beam axis and transverse to the beam, and the focus angle. A beam focussing and positioning apparatus provides focussing and positioning for the waist of a waisted beam at a desired location on a target such as an optical fiber. The apparatus includes a first lens, having a focal plane f sub 1, disposed in the path of an incoming beam and a second lens, having a focal plane f sub 2 and being spaced downstream from the first lens by a distance at least equal to f sub 1 + 10 f sub 2, which cooperates with the first lens to focus the waist of the beam on the target. A rotatable optical device, disposed upstream of the first lens, adjusts the angular orientation of the beam waist. The transverse position of the first lens relative to the axis of the beam is varied to control the transverse position of the beam waist relative to the target (a fiber optic as shown) while the relative axial positions of the lenses are varied to control the diameter of the beam waist and to control the axial position of the beam waist. Mechanical controllers C sub 1, C sub 2, C sub 3, C sub 4, and C sub 5 control the elements of the optical system. How seven adjustments can be made to correctly couple a laser beam into an optical fiber is illustrated. Prior art systems employing optical techniques to couple a laser beam into an optical fiber or other target simply do not provide the seven necessary adjustments. The closest known prior art, a Newport coupler, provides only two of the seven required adjustments

Phototropic Responses of Bugula Larvae in the Presence of Stimulating and Anaesthetic Agents

Observations on phototropic responses of the larvae of Bugula neritina and of B. flabellata in the presence of stimulating and anaesthetic agents indicate that the light reactions of these organisms may have a diagnostic value for predicting acceleration or retardation of the rate of metamorphosis. Experiments on B. neritina were conducted at the Bureau of Fisheries, Beaufort, North Carolina; those on B. f labellata, and less extensive observations on B. turrita, were made at the Marine Biological Laboratory, Woods Hole, Massachusetts
