The mid-part of the head is covered with coarse tubercles and expands forwards; the eyes include a few, very large lenses. Transparent lenses caused little distortion of the underlying grid. As in the case of the non-cataractous diabetic lenses, detailed information concerning the diabetic type, disease duration, and treatment was not distributed. Much of this is because the changes identified in the 1960s are viewed through different historical lenses. Later, with the introduction of better-quality lenses, the camera obscura would have been used for painting. The objective lenses required for cathodoluminescence must have long working distances, so choice is often limited and prices high. The overwhelming majority of respondents in both groups used corrective lenses. The overlying mudstone (in places mudstone-siltstone-sandstone alternations) is typically red and includes thin lenses or layers of dirty whitish caliche intervals. A few limestone lenses also occur at the top of the succession. Low-quality lenses collimated the light giving a nearly cubic test section of side 12.7 em. Grainstones forming lenses within reefs have significantly different attributes. Sheets and lenses of medium to coarse sandstones with quartz pebbles alternate with breccia sheets. The pouch could be observed using transmitted light and objective lenses from x 1 to x 20 magnification. However, his model did not include a criterion for formation of new ice lenses. The rat eyes were also enucleated, and the anterior chambers and lenses were removed. The eye was corrected to infinity with gas-permeable contact lenses. The first one was a complex f02 objective, with f 100 mm, producing a parallel beam between the two lenses. The first one was a complex f/2 objective, with f 1⁄4 100 mm, producing a parallel beam between the two lenses. Polymictic allogenic breccia with suevite lenses is found in the annular subsidence, and is overlain by a 50-130 m thick resurge deposit. The pelitic and semipelitic gneisses are muscovite-free and contain abundant leucocratic layers and lenses, which are inter preted as anatectic melts. As a result, lenses of undeformed sandstone, the effective 'bounding layers', change thickness systematically. As the lenses' shape was particularly irregular toward the edges, covering that part would significantly reduce aberrations. The plane-convex lenses are installed on the spherical sur face of the target chamber. We are not aware of any measurements of the spectral absorption properties of the lenses for any of these species. They also showed that intravitreal injections of glucagon completely prevented the choroidal thinning which is normally induced by wearing of negative lenses or diffusers. Another group of chicks, not treated with lenses, was injected every second day with 0.05 and 2.5 nmol agonist, respectively. Refractive and ocular changes in tree shrews raised with plus or minus lenses. Plano lenses were intended to mimic an open eye situation and control for any effect of simply wearing goggles. 463 select the preferred color from a variety of tinted lenses left unspecified. The eyes were examined regularly during the experiment and closed without contact lenses for several hours each night. Gas-permeable hard contact lenses covered the eyes to prevent corneal drying. Every 8-12 h, the contact lenses are removed and cleaned, and the clarity of the refractive media is checked with a direct ophthalmoscope. Thus, we would expect ventral system functions to be affected by the wearing of blurring lenses while dorsal system functions would be much less so. The intervening finegrained sand layers are laminated and rippled, and exhibit brownish clay lenses and escape burrows (sections 2, 4, 9). As the run continued, best of run individuals emerged with three and four groups of lenses (with the largest group containing four lenses). Locally, there are 5-cm- to 1-m-thick dunite and clinopyroxenite layers, anorthosite lenses and 10-cm-thick lenticular gabbro pegmatites. In contrast to lenses, for which the upper-layer dipolar flow always remains bounded, the case of eddies is much more complicated. We observed the following features of the evolution of lenses. Peering through traditional lenses restricts us to a predictable range of options and prevents the expanded vision these problems require. In collaborative design, stakeholders' perspectives can be visualized as "lenses" they wear during the design process. We all see the world through the lenses of our personal interests. We estimate that the layers containing obsidian cobbles are 10 -20-m thick and are in the shape of discontinuous lenses. When a person has a specific question or issue in mind, he or she tends to see the world through "task-relevant" lenses. Reducing the magnetic field strength means longer triplet lenses, which completely disturb the longitudinal beam dynamics. Therefore, the acquisition of the images was performed by a camera without lenses, operating in the dark. The variety of published analyses suggests a variety of lenses. The combined weight of both lenses was used. The ion beam was focused in a 5 mm spot on the target sur face by magnetic quadrupole lenses. Chapter 2 offers a framework of theories, or lenses, useful in understanding public provision for children. Occasional lenses of black pyrolusite, each up to tens of centimetres thick, are also present, together with widespread disseminated manganese oxide. There are also pink pelagic limestones with lenses of red chert, formed by diagenetic replacement of carbonate. A telescope with two single lenses expands the beam size to 10 mm. The lack of ice lenses at this site is not unusual. The goggles were left unmodified if they were used as clear, plano lenses. All were between 18 and 35 years of age, had normal or corrected-to-normal vision, and were tested with untinted lenses. The pupils were dilated with atropine and the eyes were protected by rigid gas-permeable contact lenses of zero added power. Contact lenses focused the eyes on a video monitor 1.14 m in front of the cat's eyes. The eyes were protected by oxygen-permeable contact lenses and focused on a tangent screen 114 cm from the animal. The monkeys wore the lenses continuously for a period of up to 8 months. Beyond this time period, missing lenses were infrequent 0.34 per week on average!. The lenses were attached to these rings and could be easily removed for measurements and cleaning of the lenses. Drugs were intravitreally injected into one eye and vehicles into the contralateral eye at the beginning of the experiment, immediately before the lenses were attached. Although the changes were small, effects of the lenses could be detected. Corneas were protected with rigid gas-permeable contact lenses; supplementary lenses were chosen (initially by ophthalmoscopy) to maximize the spatial resolution of the first recorded units. Trial lenses were used to correct refractive errors. Corneas were protected with zero-power rigid gaspermeable lenses. Instead of illuminating color vision tests, however, the new device provided illumination colors that simulated different tinted spectacle lenses. The eyes were dilated with 1% atropine sulfate, fitted with contact lenses and focused on a tangent screen 76 cm in front of the animal. With the 1880s came the production of apochromatic lenses, using different types of glass with different optical properties. Anastomosing shear planes producing shear lenses, wavy shear surfaces and foliations in basalt are commonly seen in the vicinity of the western thrusts. The status and condition of the lenses were checked frequently throughout each day; missing lenses were infrequent, but when noticed were replaced immediately. The pupils were dilated with atropine and the corneas were covered with contact lenses fitted with 3-mm artificial pupils. The first was wearing form-depriving goggles, neutral density filters, or plano lenses while under normal laboratory lighting. Negative values indicate a reduction in the number of discernible colors with lenses and positive values an enhancement. The widely preferred method of photographing buildings is cumbersome and slow, involving large format rising-front cameras and extreme wide-angle lenses. The metal bridge was gouged and his lenses abraised. The three books certainly deal with that argument, but tackle it through different lenses inherited from different traditions of scholarship, targeting various audiences. A wide variety of topologies appeared between generations 50 and 98, most having four groups of lenses. 267 as discontinuous lenses, so that no complete vertical succession of thick units occurs in one place. Among organisms present, reef-builders form extended biostromal lenses within dense growths of crinoids and bryozoans. Note the lighter colour of the bands compared with the undeformed surrounding quartzite and lenses of primary sediment between individual bands. Total height of cliff is about 90 m; (b) amphibolitic gneisses (interpreted as meta-basalts) with deformed epidote lenses. Structural changes in lenses of mice lacking the gap junction protein connexin43. Confocal scanning light microscopy with high aperture immersion lenses. Within 50 cm, fine sands and silts with occasional carbonized wood lenses abound. In the e-mail survey, wearing contact lenses was associated with conjunctivitis and with bilateral disease. Second, market knowledge paved the way for commercialization of foldable lenses, whose manufacturing had been perfected through experimentation with new materials and designs. Pumping beams are focused into the crystal from opposite sides by lenses. The array is composed of 12 10 lenses. Her approach to these sources relies on an array of interdisciplinary lenses that she uses to great effect. If occluders or lenses were lost more than once, the animals were excluded from the study. The eyes were covered with contact lenses of zero power, and curvature appropriate to focus the retina on a tangent screen at 57 inches. To detect possible pollinators, we looked f or pollen o n t he insect body using lenses (10 x). To produce the cluster of lenses that records the numerous images and then compares them for movement has been based on an insect's compound eye. The eyes were protected with oxygen-permeable contact lenses. In one case, two small lenses were present within one eye. Correction of individual refractive error, if necessary, was provided by appropriately selected trial lenses mounted in the spectacle plane. Mirrors were front sur faced, and lenses were achromatic doublets. In contrast, changes induced by negative lenses were slower and could be detected not before 1 day of treatment.
