Effect of light stress on the homoiochlorophyllous resurrection plant Craterostigma wilmsii
… wilmsii, was examined in this study. Inner-whorl leaves, which become shaded from light when dry, and outer-whorl leaves, the abaxial surfaces of which receive light in the dry state, as well as leaves which had been restrained from curling during drying, were separately examined. …

The effect of weekly handling on the temperament of peri-puberal crossbred beef heifers
… to determine if the location of the facial hair whorl was associated with any of the behavior scores or social dominance order. Crossbred beef heifers (n = 146) were assigned to be walked through, sorted and moved through a chute for 2 hr each wk for 20 wk (HANDLED) or allowed to remain on …

Modeling the diameter and locational distributions of branches within the crowns of loblolly pine trees
… the average of and range in diameter within a whorl. Attempts at modeling the height above ground to branches (whorls) were unsuccessful; therefore, equidistant spacing was assumed. Similarly, predicting the number of branches within a whorl of a certain height was difficult, and overall …

Diallel analysis of diplopodia ear rot resistance in maize and an assessment of the genetic variability of Stenocarpella maydis through isozyme analysis
… from a diseased maize ear, all applied in the whorl 10 to 15 days prior to flowering (V12 for inbreds), and natural occurrence of disease. General combining ability was significant for both 1994 and 1995 growing seasons in an analysis of the F₁ of the diallel cross, indicating that additive …

Dynamic modeling of branches and knot formation in loblolly pine (Pinus taeda L.) trees
… set was obtained from a destructive sampling of whorl sections from 34 trees growing under different initial spacing. Data from dissected branches were used to develop a model for representing knot shape, which assumed that the live portion of a knot can be modeled by a one-parameter equation and …

Reproductive Life History and Shell Shape Variation of Three Species of Elimia (Pleuroceridae) in the Lower Etowah River Basin
… by the establishment of the fourth whorl. Differences in egg oviposition among species were observed in the lab and in substrate samples obtained from the field. Our results suggest that there are at least three distinct species of <em>Elimia </em>occurring in lower Etowah River …

European corn borer resistance in sorghum compared with maize
… fed on leaf tissue in the moist area deep in the whorl of sorghum and maize plants. Resistance in sorghum, as in maize, to 1st-generation ECBs, therefore, is resistance to leaf feeding (a high level of antibiosis against 1st- and 2nd-instar larvae). Dried-ground leaves (substituted for wheat germ …

Environmental change impacts on shell formation in the muricid Nucella lapillus
… form narrower shells with a higher spire to body whorl ratio. In contrast, populations in regions with a higher SIR form wider shells with a much lower spire to body whorl ratio. The results suggest a widespread phenotypic response of N. lapillus to continuing ocean acidification could be …

An investigation into temperament, production, and their physical indicators in Bos taurus beef and Holstein dairy cattle
… Physical attributes examined were facial hair whorl characteristics, and cannon bone measurements. Three separate groups of cattle were used to evaluate the possible relationships. The first group studied were cows at a small Holstein dairy. A simple method to determine the temperament of dairy …

Cretaceous Nerineacean gastropods
… continuous variation in overall shell shape and whorl concavity. However, external ornament and internal fold pattern do not show significant intraspecific variation; these features therefore provide reliable characters for species definition.

A Role for Late Meristem Identity2 in the Reproductive Development of Arabidopsis
… of floral meristems in the axils of the first whorl organs. These floral meristems give rise to "branched" flowers. Here we present a possible role for LMI2 during floral primordia growth. Similar to SVP, AGL24 and SOC1, AP1 downregulates LMI2 in young flower primordia thus preventing the …

In vivo confocal microscopy of the cornea in health and disease
… an overall radial pattern with a clockwise whorl at the area of convergence, inferior to the corneal apex. Keratoconic corneas demonstrated gross abnormalities of the nerve plexus even in mild cases. A two-dimensional reconstruction of the inferior limbus was also produced using this method. …

Definition of Agrostis palustris leaf health at the time of infection and colonization by Curvularia lunata
… and the fourth leaf had not yet emerged from the whorl. Plants were then treated with TCA for 6 times on alternate days. Half of the plants were high air temperature stressed at 38°C for 18 hr before plants were inoculated. Leaf health was estimated throughout the growing period of the plants by …

The etiology of the decline of eastern white pine (Pinus strobus L.) on Virginia landscapes: a survey of stress factors
… of tree ring increments and inter-branch whorl measurements converted to percent growth per year, and seasonal foliar color changes using a Munsell rating index. Site quality indicators centered around the soils with soil pH, clay content, amounts of compaction and soil disturbance as the …

Characterisation of silica in Equisetum hyemale and its transformation into biomorphous ceramics
… and is distinguished by jointed stems with fused whorl of nodal leaves. The plant has been used for scouring kitchen utensils and polishing wood during the past time due to its high silica encrustations in the epidermis. Equisetum hyemale (scouring rush) can accumulate silica up to 16% dry weight …

Klasifikace otisků prstů
Automatická identifikace založená na otiscích prstů vyžaduje porovnání otisku prstu s velkým množstvím otisků prstů uložených v databázi. Klasifikace otisků prstů poskytuje důležitý mechanizmus indexování v databázích otisků prstů, který snižuje čas vyhlehledání a výpočetní nároky. Tato práce se …
