TL;DR: A Simple Tandem Repeat sequence of 11 nucleotides has been found in the ITS1 region of the rDNA of members of Order Xylariales, and it is shown that the presence of this sequence increases the normal rate of divergence in theITS1 of the Xylariaes.
Abstract: A Simple Tandem Repeat sequence of 11 nucleotides has been found in the ITS1 region of the rDNA of members of Order Xylariales. The number of repetitions detected ranged from one to six, and they could be found in pure tandem or interspersed. The same core sequences have also been found in DNA from other organisms, although usually not repeated in tandem. These repetitions could have been generated by slipped strand mispairing. The presence of this sequence increases the normal rate of divergence in the ITS1 of the Xylariales. The phylogenetic implications of the presence of this sequence in the molecular taxonomy of Xylariales are also discussed.

TL;DR: In this article, the Abbreviated Vigilance Task (AVT) and Continuous Attention Test (CAT) were applied to a sample of 829 candidates in a job-selection process for air-traffic controllers, and neither of them showed discriminative capacity.
Abstract: Summary: Deterioration in performance associated with decreased ability to sustain attention may be found in long and tedious task sessions. The necessity for assessing a number of psychological dimensions in a single session often demands “short” tests capable of assessing individual differences in abilities such as vigilance and maintenance of high performance levels. In the present paper two tasks were selected as candidates for playing this role, the Abbreviated Vigilance Task (AVT) by Temple, Warm, Dember, LaGrange and Matthews (1996) and the Continuous Attention Test (CAT) by Tiplady (1992). However, when applied to a sample of 829 candidates in a job-selection process for air-traffic controllers, neither of them showed discriminative capacity. In a second study, an extended version of the CAT was applied to a similar sample of 667 subjects, but also proved incapable of properly detecting individual differences. In short, at least in a selection context such as that studied here, neither of the task...

TL;DR: El presente trabajo muestra los resultados de una serie oficiales de ensayos de proteccion en pino llevados a cabo con varios aislados pertenecientes a una nueva especie del complejo de hongos Rhizoctonia, que confirmaron the hipovirulencia de los aislado supuestamente protectores para las plantulas de pino.
Abstract: El presente trabajo muestra los resultados de una serie de ensayos de proteccion en pino, llevados a cabo con varios aislados pertenecientes a una nueva especie del complejo de hongos Rhizoctonia: C.albasitensis V.Gonzalez & V.Rubio. Como patogenos se emplearon cepas de R.solani AG-4, aisladas de invernaderos productores de planta forestal en Cazorla (Espana) responsables de ocasionar la enfermedad conocida con el nombre de tumbado o “damping-off”. Estos experimentos se realizaron a escala de laboratorio e invernadero, observandose en ambos casos altas tasas de proteccion biologica. Con anterioridad a tales experimentos de proteccion, se dispusieron una serie de tests de patogenicidad que confirmaron la hipovirulencia de los aislados supuestamente protectores para las plantulas de pino.
