Growing degree day models can successfully predict the performance of gibberellin-inhibiting plant growth regulators (PGRs) applied to cool-season golf putting greens. These models are effective because metabolism or degradation of PGRs was found to be directly related to air temperature. Relative clipping yield of turfgrasses treated with PGRs follow a sinewave model with a period of growth su...

Pythium species were isolated from diseased samples of creeping bentgrass and annual bluegrass. Among fourteen isolates from decayed roots and crowns, seven were P. graminicola, five were P. torulosum and two were P. ultimum. These species were identified by comparison of cultural and morphological characteristics to literature and reference isolates. In a tissue culture plate assay for quantif...

Endophytes are microbes that inhabit internal plant tissues without causing disease. Some endophytes are known to combat pathogens. The corn (maize) landrace Chapalote has been grown continuously by subsistence farmers in the Americas since 1000 BC, without the use of fungicides, and the crop remains highly valued by farmers, in part for its natural tolerance to pests. We hypothesized that the ...

Rotation of an inclined surface on which Helix is creeping straight upward, such that the axis of the animal is turned at a right angle to its previous position, but in the same plane, leads to negatively geotropic orientation after a measurable latent period or reaction time. The duration of the latent period is a function of the slope of the surface. The magnitude of the standard deviation of...

introduction: mother as the main attachment figure has an undeniable effect on affective development of the child. the aim of the current study was to investigate the relationship and predictability of girls` attachment problems through mothers` attachment style. method: sample included 388 individuals of second and fourth grade of primary school that had been chosen through multistage cluster ...

We show that if a Lévy process creeps then, as a function of u, the renewal function V (t, u) of the bivariate ascending ladder process (L−1,H) is absolutely continuous on [0,∞) and left differentiable on (0,∞), and the left derivative at u is proportional to the (improper) distribution function of the time at which the process creeps over level u, where the constant of proportionality is d H ,...

Some researchers report that one potential tool for reducing fungicide requirements on turfgrasses may be the use of silicon (Si) fertilizers. Silicon has been reported to suppress diseases on various crops in the last decade (Raid et al., 1992; Cherif et al., 1994; Deren et al, 1994; Seebold et al, 2000; Seebold et al., 2001). Researchers in North Carolina found that brown patch and dollar spo...

This paper estimates separately the components of scattering waves generated in cylinder-body model for body area networks. For the evaluation, scattering field formulations in relation to uniform cylinderand slab-body models are provided, and the reliability of the analyses is testified by the comparison with results computed by the finite-difference time-domain (FDTD) method. Creeping waves, ...

Knee injuries are common in football, frequently involving damage to the meniscus and articular cartilage. These injuries can cause significant disability, result in loss of playing time, and predispose players to osteoarthritis. Osteochondral allografting is an increasingly popular treatment option for osteoarticular lesions in athletes. Osteochondral allografts provide mature, orthotopic hyal...

TOPIC Attachment theory and reactive attachment disorder (RAD). PURPOSE To highlight current perspectives on attachment theory, RAD, and treatment implications using a case study of an 8-year-old patient with RAD. SOURCES Selected multidisciplinary literature related to attachment theory and RAD. CONCLUSIONS The literature provides a body of work that substantiates the importance of early...
