IMPORTANCE Relatively little data exist about the long-term outcomes of an initial glaucoma drainage device (GDD) and subsequent GDDs implanted in pediatric patients with glaucoma. OBJECTIVE To determine the long-term outcomes of the first and second GDDs and risk factors in pediatric glaucoma. DESIGN, SETTING, AND PARTICIPANTS Retrospective review of 119 eyes of 89 patients younger than 18...

this study was conducted at the gorgan university of agricultural sciences and natural resources farm, iran, golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on azivash (corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. treatments were four sowing dates such as may 5, jun 5, ju...

in order to determine probable effects of sowing dates on partitioning coefficient of dry matter to different organs (leaf, stem and reproductive organs) in different wheat varieties (koohdasht, zagros and tajan) an experiment with crbd design and four replications was conducted. 5 sowing dates were included (29 december, 2007, 30 january, 2 march, 27 march, 1may, 2008). in order to quantify pa...

seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. in order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

An increasing world population and the competitive nature of the stone fruit market, particularly nectarines [(Prunus persica var. nectarine)], demand the selection of fruit with high quality attributes, flavor, and a wide range of maturity. Information on this subject is limited at the present time. In search of superior nectarines, a trial was conducted to study growing degree days (GDD), ful...

The relevance of intracavity dispersion control in passively mode-locked ultrashort-pulse laser was recognized soon after the appearance of the first systems operating in the femtosecond domain.' Negative dispersion that is due to wavelengthdependent refraction in a pair of Brewster-angled prisms combined with positive material dispersion proved to be an efficient and convenient means of contro...

The data used in the present study is a 21-year GIMMS-NDVI dataset, surface data on phenology of birch, and temperature data from meteorological stations, all for the period 1982 to 2002. For each pixel a 21-year mean and a mean of peak NDVI value was computed. Threshold values related to this mean, and mean of peak NDVI values, which show the best correlations with the phenological field data ...

Increasing temperatures in the US Midwest are projected to reduce maize yields because warmer hasten reproductive development and, as a result, shorten grain fill period. However, there is widespread expectation that farmers will mitigate yield losses by planting longer season hybrids lengthen Here, we ask: (a) how current hybrid maturity length relates thermal availability of local climate, an...
