Rounded structures

The toroids show an interesting change in overall morphology as they become larger, at least at the lip.The hypothetical small toroid shown in Fig. 3a is actually quite smooth and essentially a fairly rounded structure. As the structures become larger, the strain... 

The pituitary gland lies deep within the cranial vault, connected to the brain by the infundibular stalk (a downward extension of the floor of the third ventricle) and protected by an indentation of the sphenoid bone called the sella turcica (see Fig. 50-1). The pituitary gland, a small, gray rounded structure, has two parts ... 

The human caliciviruses, norovirus (NoV) and sapovirus, have also been described as small round structured viruses, for their 27-30 nm capsids. The NoV capsid consists of 180 copies of the VPl major capsid protein packed as an icosahedron (Prasad et ah, 1999) and the VP2 minor capsid protein, which may contribute to stability (Bertolotti-Ciarlet et al., 2002). The S domain of VPl forms the inner shell of the capsid, while the P domain protrudes from the capsid surface and contributes to binding the histoblood group antigen receptor (Cao et ah, 2007) and antigenicity (Donaldson et ah, 2008 Lindesmith et ah, 2010).

Global chemicals giant Mitsubishi Chemical created a company named Frontier Carbon Corporation to manufacture tiny, high-strength carbon structures known as fiillerenes or bucky balls. Technically speaking, a fiillerene is a microscopic, round structure that is geodesic in nature. It has 60 joints across the rounded surface,...

Obstruction of a large bile duct leads to dilated intrahepatic bile ducts, which appear on CT scans as ramified linear or rounded structures with bile-equivalent density. Their luminal diameter increases progressively in the direction of the hilus. (47) Segmental dilation of the bile ducts may be indicative of a tumour. A dilation of the bile duct of >9 mm points to a peripheral obstruction, mostly near the papilla of Vater. 

A large body of literature describes the occurrence of pores, of various sizes and lifetimes, as the result of electroporation. In uiuo these pores may not necessarily be neatly rounded structures, but rather a mixture of shapes of permeabilization structures depending on the effect of transmembrane protein domains, cell shape, and surrounding matrix on the cell membrane response to the field, i.e. these permeabilizahon structures could either be circular in form, or have other forms depending on local factors. 

A node is a knot or small rounded structure, which in this instance consists of special nerve fibers. 

Each DNA molecule is folded into a tangled mass that forms one of the cell s chromosomes. The DNA molecule is amazingly long and thin if the largest human chromosome were stretched out, it would be 4 cm long in the cell nucleus, however, it is wound into a rounded structure only 5 nm wide—8 million times shorter ... 

Rayon (left) has a lobed cross section which is typical for fibers spun industrially by the viscose process. In contrast, Lyocell (middle) displays a round shape similar to the cellulose carbamate example (right). (In all the micrographs, the dark streaks are overlaps of sample material caused by the cutting movement of the ultra microtome knife.) Cross sectional shape and pore structure are strongly dependent on the precipitation conditions. For NMMO fibers [11] it was shown that harsh precipitation with water gave dense, round structures while softer precipitation into alcohols lead to a skin-core stmcture with dense skin and a porous inner region. StiU, cross sections are round in contrast to viscose-ty fibers. 

The MCS reaction is a solid/gas reaction, so that it is natural that morphological effects of the solid components of the reaction should be important. Workers at Wacker defined a surface area parameter, QF, which relates the ratio of elongated to round structural forms. MCS promoters controlled by employing Si particles for a given surface area defined the ratio QF as the ratio of the area portion of intermetallic phases at grain boundaries to the area portion of intermetallic phases in primary silicon. These workers found that maximum Di was obtained for silicon particles having QF = 18-60. Furthermore, the rate was effected by QF, so that for CuO, ZnO, and Sn and Si with QF = 29.55, the... 

The work on slotted approaches in wireless communications, both for data and voice, is rather vast and old. For example, in [9,10,11] the authors propose using dynamic TDMA frameworks where slots in a static round structure are assigned dynamically to nodes. However, these approaches are normally centralized in which a master receives slot requests and assigns slots to nodes dynamically. The original Point Coordination Function (PCF), as well as the more recent Controlled Channel Access (HCCA) of the Hybrid Coordination Function (HCF), of IEEE 802.11 also work in a similar manner with the AP scheduling the nodes traffic in a centralized collision-free way. Conversely to these approaches, we seek a fully distributed access coordination scheme, which is a typical property of TDMA protocols. 

In practice this is achieved with timers that trigger the respective transmissions. However, this approach may perform poorly, with high significant packet losses during certain periods of time, herein called critical periods, independently of the network load. This is the case in the presence of interfering external periodic traffic with approximately coherent periods. In this case, given the fixed TDMA round structure, the protocol will continue triggering transmissions at the same time as the interference source, until the clock drifts eventually set those instants apart (Fig. 2). 

The work in [4] includes both the adaptation mechanism as well as a dynamic reconfiguration of the round structure, according to robots that dynamically join and leave the team. This is orthogonal to the current work and thus it will not be considered here. The focus will thus be on the adaptive TDMA mechanism, only. 

In the condition that the ratio of H2/N2 is less than stoichiometric ratio, Ru catalyst has very high activity and is insensitive to ammonia. So, synthetic ammonia reaction can use the syngas with excessive NH3 on Ru catalyst and decrease the quantity of circulation gas, i.e., it is possible that the reaction is first carried out on Fe catalyst in the condition of stoichiometic ratio of H2/N2 and then is carried out in supplement on Ru catalyst in the condition that the mole ratio of H2/N2 is (2.2-2.8) l and with excessive N2. The round structure of auxiliary converter, with...
