Adjacency structure

Eollowing the computational protocol of Czerminski and Elber [39,40] a number of restraints and constraints are added to (1) encourage the mean-square distances between adjacent structures to be approximately constant. 

Care has to be taken to ensure that downdrafts do not cause the combustion products to be liberated in the occupied space. To achieve this, it is essential that the stack is of such a height that wind deflecting off adjacent structures does not influence the free passage of the products of combustion. 

The effect of stray currents arising from a d.c. source or from cathodic protection of an adjacent structure are considered in Sections 11.5 and 11.6. 

Bond a conductor, usually of copper, that connects two points on the same structure or on different adjacent structures, and thus prevents significant differences in potential between two points.

At a first glance this subtraction appears to be a violation of the zero-sum rule. However, here an exception has to be made, because particles merge upon direct contact of adjacent structural entities, and thus the number of particles is reduced — just by the amount deduced by RULAND. 

A urinary tract infection (UTI) is defined as the presence of microorganisms in the urine that cannot be accounted for by contamination. The organisms have the potential to invade the tissues of the urinary tract and adjacent structures. 

Men with disease fixed or invading adjacent structures other than the seminal vesicles (T4) are at very high risk for recurrence. Androgen ablation should be initiated at diagnosis instead of waiting for the onset of symptoms. 

Outdoor transformers should be physically separated from adjacent structures and from each other by firewalls, spatial separation, or other means for the purpose of limiting the damage and potential spread of fire from a transformer failure. 

Unless consideration of these factors indicates otherwise, NFPA 850 recommends that any oil-insulated transformer containing 500 gal (1,893 I) or more of oil be separated from adjacent structures by the distances in Table 8-20. If separation can not be obtained, then either a fire barrier or water spray system designed for 0.25 gpm/ft (10.2 Ipm/m ) should be provided. 

Developing plans for response to credible fire events is an important emergency planning element. Different fire events require different responses. Complete extinguishment is the appropriate approach for some events. For others, the optimum approach may be to cool adjacent structures until the source of the fuel can be isolated or until the fuel is depleted. Still others may require that firefighters secure perimeter areas and allow the fire to burn itself out. 

Install an enclosed wash rack for equipment in an adjacent structure with drain connected through a sump (pump installed) for disposal of wash water from tank and equipment. Wash rack must have a cleanout trap for removal of soil and other debris from equipment.

Additionally, ultrasound may show a thickened gallbladder wall or tumor extension into the liver. However, CT scans are more helpful in assessing adenopathy and the spread of disease into the liver, porta hepatis, or adjacent structures. ERCP or transhepatic cholangiography (THC) may be useful in the presence of obstruction to localize primary tumor. 

Gallbladder cancer is staged primarily at the time of surgery. Specifically, the stage is determined by lymphatic involvement and extension to adjacent structures (Table 4). The 5-yr survival rate is 83% in patients having T1 lesion, and only 33% in patients having T3 lesions. In patients who have involvement of the lymph nodes or metastatic disease, the 5-yr survival rate ranges from 0-15%.

Remove each forelimb from the torso with a single cut, taking care not to damage any adjacent structures. 

The one we choose is an adjacency structure. An adjacency structure for a graph G = (V,E) is a set of lists, one for each vertex. The list for vertex v contains all vertices adjacent to v. Note that a given edge (v,w) is represented twice w appears in the adjacency list for v and v appears in the adjacency list for w. See Figure 3(c). 

An adjacency structure is surprisingly easy to define and manipulate in FORTRAN or any other standard programming language.

Other structures have recently been stimulated including the motor cortex [52], the pedunculopontine nucleus in the brain stem [54] and the zona incerta (a structure adjacent to the STN) [55]. This indicates that the stimulation of various structures along the motor loop can lead to improvement of parkinsonian signs but spreading to other adjacent structures cannot be excluded. In the present chapter we focus on DBS of the STN.

Preseptal or periorbital cellulitis is an infectious process involving lid structures anterior to the orbital septum. The condition generally occurs due to one of three clinical scenarios (1) secondary to a localized infection or an inflammation of the eyelids or adjacent structures (i.e., sinusitis, conjunctivitis, blepharitis, and/or internal hordeolum), (2) secondary to eyelid or fecial trauma, and (3) after an upper respiratory tract infection. 

Two of these directions correspond to up and down along the myosin duead, and the connections in the two lateral directions are also directed upwards and downwards. It is natural then to relate dtese four-coordinated channel regions of the Q surface to the myosin heads. Thus the possible connections via the 3i-centred actin threads of myosin threads have only two directions, which fulfil the crystallographic symmetry of the surface. It is proposed here that these two directions correspond to the initial direction of the myosin head before movement and the end direction after movement, respectively. In this model of the contraction, the time-phase of mobility represents a transient disorder condition of adjacent structure elements, whereas the structure as a whole fulfils the required crystallographic symmetry. If the individual molecular conformational changes must be accommodated within the periodicity of the surface, the necessary perfect long-range synchronisation of mobility over the entire muscle seems a natural consequence.
