Space Invaders

Then came the games, and most older readers will recognize the Space Invaders screen shown below. ..

Departing from the known fact that PVC melts have a nodular structure, about 1 micron in size, the authors assumed that white ash particles invaded the inter-nodular spaces, thereby causing the nodules to move apart and the chains between them to be broken as a result the nodules acquire more freedom to move. As the filler concentration is increased, the contribution to viscosity increase... 

In many ecosystems, plants tend to pattern themselves as pure stands or as individuals spaced in rather specific densities or configurations. Many desert species show obvious zones of inhibition around which few, if any, alien species are able to invade. These patterns often cannot be adequately explained by competition alone, and are probably caused by a combination of factors including allelopathy. The phenomenon happens with herbaceous plants as well as woody shrubs and trees. 

Moreover,bioactive lipids maybe considered dual messengers they modulate cell functions as messengers and they become part of the response of the nervous tissue to injury, broadly referred to as the inflammatory response. This response occurs in ischemia-reperfusion damage associated with stroke, various forms of neurotrauma, infectious diseases and neurodegenerative diseases such as Alzheimer s disease. Inflammation in the nervous system differs from that in other tissues. If the blood-brain barrier is broken, blood-borne inflammatory cells (e.g. polymorphonuclear leukocytes, monocytes, macrophages) invade the intercellular space and glial cells are activated, particularly microglia, which play a prominent role in the inflammatory response. These responses may... 

Chronic inflammation of the synovial tissue lining the joint capsule results in tissue proliferation (pannus formation). Pannus invades cartilage and eventually the bone surface, producing erosions of bone and cartilage and leading to joint destruction. The end results may be loss of joint space, loss of joint motion, bony fusion (ankylosis), joint subluxation, tendon contractures, and chronic deformity. 

Blood vessels penetrating tumors provide malignant cells with another point at which to enter the circulation. Evidence exists that in situation where cancers disseminate predominantly by the blood, the extent of metastasis depends upon the vasculature of the primary tumor. Thin-walled capillaries, especially those newly formed, provide poor resistance to invading cancer cells. Also, data from microscopy studies show that the endothelium of tumor vessels, particularly in areas of poor oxygenation, is often abnormal (Kl). These abnormalities may permit invasion by neoplastic cells (P3). Finally, tumors can spread by direct extension into body cavities such as pleural and peritoneal spaces. An example of this is the formation of peritoneal metastases from ovarian carcinoma. 

The expected channel shown in Figure 12 is of a bimolecular structure. The rigid channel mouth may prohibit the consecutive long alkyl chains from assembling themselves and to prevent lipid molecules from invading the area. The space thus provided may accommodate water molecules to make the domain sufficiently hydrophilic to pass ions. Such a domain would recognize its counterpart located in another lipid layer to make a tail-to-tail dimer of 8, i.e. a symmetric transmembrane channel, as in the case of Gramicidin A dimer. ... 

At 10 MPa and 35 °C, C02 has a density of approximately 700kg/m3. Under these conditions, a cubic meter of sandstone with 10% porosity contains approximately 70 kg of C02 if the pore space is completely filled by C02. However, saturation of C02 is not complete, and some brine remains in the invaded pore spaces (Saripalli McGrail 2002 Pruess et al. 2003). In addition, non-uniform flow of C02 bypasses parts of the aquifer entirely. Darcy-flow based analytical and numerical solutions are used to evaluate some of these effects by simulating the advance of the C02 front over time-scales of decades to hundreds of years and over lateral distances of tens to hundreds of kilometers. To account for the extreme changes in density and viscosity of C02 with pressure and temperature, these models must incorporate experimentally constrained equations of state (Adams Bachu 2002). 

Some folks put off retirement because they fear their life partners will control their free hours. It will be Honey, do the dishes, Honey, do the windows, and Honey, take the dog to the vet. Normally these individuals need not worry because most partners don t want someone underfoot, monitoring their activities and invading their space. One woman expressed it well The only time you will... 

Another strategy includes respecting people s personal space. There is a prescribed area that surrounds a person and should not be entered. This space decreases with your knowledge of the person. It may be disconcerting for coworkers when you stand over their shoulders, but may feel normal to close friends. People can be put on the defensive when you invade their space.
