Big vein of lettuce is a disease well known to lettuce growers in California and Arizona. The disease is characterized by coarse chlorotic bands along the leaf veins, as shown in photo, and by a delay in maturity and a reduction in head size. The d

Optically pumped CO 2 lasers can operate with high efficiency, high repetition rate and large bandwidths, suitable for producing ultra-short pulses at terawatts to petawatts, in contrast to conventional discharge-pumped CO2 lasers, which are restrict

Objectives: Minimally invasive saphenous vein harvesting is advocated to reduce wound morbidity. Our early experience with minimally invasive techniques, however, suggested that increased tissue traction and trauma might follow. We aimed to test the

Although the ferox of Scottish Highland lochs (lakes) have long captured the interest of both laymen and scientists, no previous investigation of their biology or ecology has been undertaken. This paper is based on 141 ferox from 22 lochs collected d

An inexpensive, compact, three‐electrode (trigatron) switch utilizing transverse gas flow was developed for burst‐mode applications. The switch is cooled by adiabatic expansion from three built‐in miniature nozzles and the interacting flow stre

Aqueous‐electrolyte resistors were developed for use as dummy loads in pulsed power systems. These resistors are simple, robust, low‐inductance devices capable of operation at high voltage and high current, and may be used to dissipate large puls

A numerical model of a three-mirror resonator for a TE CO(2) laser was developed. This model was used to determine if a three-mirror resonator with an etalon could be used to ensure tunable single-mode action on the lower gain lines of CO(2). Single-
