Termites tunnelled slowly in the dry sand, but diverted their tunnelling into the wet sand once it had been discovered. Both are usually estimated using data derived by scanning tunneling microscopy from different surface specimens. The percentage of stem tunnelled, internodes bored and cobs damaged did not significantly vary among treatments in the insecticide-treated plots (table 5). The arenas were typically explored to their edges after four days, with all solid objects and gaps interconnected with many tunnels. Of course new food sources will be discovered and the laboratory studies of tunnelling behaviour may yield valuable insights into this process. Extract-treated sand barriers deterred tunnelling completely for 2-4 days at the higher extract concentrations tested, although partial penetration was seen in succeeding days. Dynamically controlled protein tunneling paths in photosynthetic reaction centers. The rolling and tunnelling dung beetle species used in this study, were selected for their large size and/or abundance. The three chambers were connected in series by two, 4 cm in diameter, tunnels which only permitted the adolescents to shuttle between the chambers. The number of tunnels was determined as the number of points where termites were excavating. We need to detect the nuclear products of the weak interaction if we are to search for resonant tunneling at low energy. Physical models and simulators, such as wind tunnels, are also commonly used to analyze the behavior of designs when the mathematics required are formidable. A good example is the use of wind tunnels to evaluate the aerodynamic proper ties of vehicles under various conditions. The theory can be tested using wings with various cross-sections in wind tunnels. The experimental apparatus was designed to mimic natural foraging tunnels of termites and to allow for rapid and simple sampling of feeding sites. When you look at these hangars from afar, you ask what these half-buried tunnels can be. All tunnels, their position of origin and length were recorded. Termites always chose to explore gaps thoroughly before they began tunnelling in the sand. Three phases were designated according to tunnelling activity. In a second set of experiments, the behavioural response was analysed using two different flight tunnels with different and/or combined stimuli. Probes of hydrogen tunneling with horse liver alcohol dehydrogenase at subzero temperatures. The rate then would still depend mainly on g, but with a matrix element for nuclear tunneling replacing the usual electroniccoupling matrix element. Superexchange models are better suited to the description of tunneling through inhomogeneous media. The good agreement with experiment for the classical calculation suggests that tunneling transitions do not provide a major contribution to the cross section. Bond-mediated electron tunneling in ruthenium-modified high-potential ironsulfur protein. There was also evidence in a number of places that cercariae, tunnelling horizontally beneath the stratum corneum, led to its separation from the underlying epidermis. The discovery of thrombus in the lateral tunnels in these 2 patients were incidental findings at routine echocardiography. In 3 neonates, the defects were multiple meshlike tunnels, and their diameter was difficult to measure. 235 mentioned where micro-manipulation is carried to the extreme of controlling the tip of a scanning tunnelling microscope, with force feedback transmitted to the operator. The colonization rate of this species was high in many patches (judged by abandoned egg tunnels) but only a few breeding attempts were successful. Almost all tunnels that originated from the front gap were excavated at the two ends, along the side edges of the arena. The 1949 excavation demonstrated the impossibility of such tunnelling - the altar lacked foundations and had to be demolished. In some cases it was possible to follow larval tunnels and find the fate of living larvae. Likewise, severity of borer damage, as evidenced by the % stem tunnelled and % cob damaged, was directly proportional to numbers of attacking larvae. Images of the figurine revealed the extent of cracks and insect tunnels and were then used to assess the structural integrity of the figurine. During phase 3 there was a steep decline in termites tunnelling in the wet sand and an increase in their tunnelling in dry sand. Only the cardboard was sampled, thus ensuring that the tunnels were left intact. They complete their development and pupate at the beginning of their tunnels. One of the tunnels was a carefully designed, low-turbulence facility. The agreement is evidence in suppor t of this selective resonant tunneling model. Modeling the kinetics of multistep tunneling processes is a straightforward problem that can be solved analytically without employing simplifying approximations. Endergonic reactions, however, become less effective as the temperature decreases, so that multistep tunneling with highly endergonic steps will exhibit a strong dependence on temperature. The temperature independence indicated that the electron was tunneling between redox sites. A method invented earlier in scanning tunnelling microscopy was applied to measure the motion of the cantilever. The classical trajectory calculations do not account for tunneling transitions allowed by quantum mechanics. A high value means a high computational cost in the calculation of the successive dynamic tunnels. The passage of particles observed in the tunnels, now extremely reduced, of the vitelline envelope demonstrates that their interactions through the interface still exist. After three days, these tunnels were up to four times more numerous and up to nine times longer compared with tunnels excavated elsewhere. Without access to the tunnels or, for that matter, parking lot containers, the recovery of surface remains came to a virtual halt. The areas selected for excavation, our research strategies, and our methodologies-especially for the tunneling operations-were planned with continual reference to these research objectives. In this case the electrons are said to have leaked or tunneled into the oxide. The inclusion of the jacket means that the refracted and tunnelling modes form a discrete spectrum, which is then amenable to our method of approximation. Unlike trenching, tunneling allows more complete documentation of architecture without destroying overlying construction. The papers in this special topic provide further support for such a tunneling approach. Crystals containing photoactivatable donors and acceptors at specific lattice sites are ideal media for investigating tunneling between proteins. Calculations of isotope effects in elimination reactions - new experimental criteria for tunneling in slow proton transfers. There are several ways to include nuclear tunneling in expressions for the rate of electron transfer. The robot has passed through two tunnels to minimize its exposure to the free spaces. During the vitellogenic period, there is an increase in the number and length of the micro- and macrovilli, which become regularly arranged inside fibrillar tunnels. Significantly more and longer tunnels were excavated from the end of gaps at the far end of the arenas, and relatively little tunnelling occurred around and along objects. Such modes are known as tunnelling modes. Modifications can be made for a finite cladding by using complex rays as in [4]; the correction to the eigenvalues is exponentially small for bound and tunnelling modes. As this essay illustrates, grand projects that sought to display the utility of colonial knowledge failed when tunnels collapsed and roads were washed away by the rains. As large bodies of men moved through the countryside their influence upon localities became evident in more than simply the cuttings, tunnels and trackbeds they left behind. The termites tunnelled slowly in dry sand, but after discovering a patch of wet sand, increased tunnelling five-fold until it was completely explored, after which activity declined. The length of all the tunnels on each day was added for analysis, because using the above rule, it was difficult to ascertain the original from secondary tunnels. The type of flow investigated here is encountered in extraction columns in chemical engineering, and can also be found in closed channels such as tunnels and mine shafts. Nicotinic acetylcholine receptor at 4.6 angstrom resolution: transverse tunnels in the channel wall. If subsequent isolation experiments were intended, freshly drilled salt cores were used, which were transported from the mine tunnels to the laboratory in sterile plastic bags. Note that similar results in generating effective transparent conditions have been obtained by the author for the problem of transonic flow in wind tunnels [22, 23]. However, the other three studies utilized wind tunnels with slotted or perforated walls to compensate for blockage and it is possible that this may have resulted in an overcompensation. We thank them all for their support, especially the many local workers whose enthusiastic efforts to dig tunnels with us allowed us to obtain the invaluable data described here. The external electron, because of fast tunneling ionization, can be considered as bound only by a soft-core effective potential, the result of the nuclear attraction and screening. There is a practical upper limit to the separation distance between redox sites ; if charges must be transferred farther than this range, then multiple tunneling steps are required. Many of the applications for this technology will be areas where airflow is constrained and deflected by obstacles such as inside buildings, mines and subway tunnels. Therefore, this interception is analogous to intercepting flying insects with aerial traps because the underground tunnels are conveyors of pheromones that elicit recruitment of termites to monitoring stations with wood. Immediately following penetration, features such as lifting of the stratum corneum and tunnels in the epidermis were observed, exactly as described by other workers studying migration in normal body skin. Due to the small fraction of light that tunnels out of the cavity, one observes radiation emission from the target for a time much longer than the pulse duration. The most important result of this paper is that one needs electron injection via tunneling ionization into the highintensity center of the multi-cycle laser pulse to achieve high energy gains. Wild animals were another threat to the integrity of fence lines, antbears tunnelling under them and baboons lifting them to create ingress for jackals and other stock predators. At harvest, the following additional data were taken: plant height (cm), stem diameter (cm), % stem tunnelled, cob weight (g), cob length (cm), cob width (cm), % cob fill and % cob damaged. One type uses a strip of rectus fascia tunnelled under the bladder neck, which is then sutured to the rectus fascia on each side with minimal tension. All traffic, both freight and passenger, has to pass through these two tunnels. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 The entire drum was dug out of the ground, which would have destroyed any foraging tunnels (indicated with the black filled line). The itinerant specialist and the gradual erasure of local variation were as much the product of the railway age as its viaducts and tunnels. Involving aqueducts and tunnels, it was a demonstration of engineering potential of transforming importance. The project embraced wind tunnels, work shops, engineering projects, and industry. Many experiments have been devoted to the time history of homogeneous, isotropic turbulence produced by a grid in uniform flow wind tunnels under neutral conditions. Very few tunnels were dug along the front gap. In contrast, the way in which termites dig tunnels has been investigated only in the laboratory. In stark contrast, the termites excavated more frequently and produced longer tunnels at the far end of the second choices. Estimated distance dependence for tunneling through vacuum is shown as a grey wedge. Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals: effect of temperature and pressure. Frequencies are given as numbers of site records and are based upon starting sites of egg tunnels. In order to emphasize this dependence between two steps, we may call it as the selective resonant tunneling model. Aerodynamics - supplementing the use of high-cost wind tunnels, the aerodynamics of a car can be analysed to reduce resistance and losses in turbulence. The spaces between them, called channels, would be a direct pathway from the blood capillaries along the tunnels of the vitelline envelope towards the oocyte.
