But attachment is not enough ; the gp120 also needs to plug into a co-receptor molecule on the cell that helps pull the virus into contact with the cell 's surface so the two can merge . Temporary surface , no road markings , bends , and heavy fast traffic . Its a semi matte surface so the blacks are not as deep as I like . If cold plasma techniques are to be controlled in modifying polymer surfaces , the plasma-induced molecular fragmentation processes have to be understood . Slashes on the timber created a rough surface so the plaster would adhere . Essential features of the module are the use of the statistical software package , Data Desk , both in lectures and in the computer laboratories , and a series of problem solving workshops in which students will work in teams . As each new tape surfaced , each new detail arose , of Secret Service logs showing late-night visits when Hillary was out of town , of presents sent by courier , of a dark dress saved as a souvenir , spattered with the President 's DNA , the American public began stripping Bill Clinton of the benefit of the doubt . For important classes of varieties , such as cubic surfaces , the conjecture is still open . The bottom half of the cockpit can lower to the surface so the astronauts can get out of the cockpit and walk around and can also lower equipment for the astronauts to use . Three major " time zones " surfaced , each with its own market drivers and most appropriate strategies . They dealt inter alia with films at liquid-liquid interfaces , interfacial tension measurements , surface ageing phenomena , the structures of films and liquid surfaces , the role of hydrogen bonding in condensed monomolecular films , applications of the Gibbs Adsorption Equation to solutions of paraffin-chain salts and to colloidal electrolytes , the effects of soaps and synthetic wetting agents on the biological activities of phenols , the penetrations of molecules through membranes and surfaces , and in some detail the properties of protein films . If heavy rains occur after sowing , packing the soil surface , no seedlings may emerge . The tactile quality of natural surfaces , the crumbly limestone walls , roof thatch , and dusty road , are recreated by the built-up paint texture . Tensions based on class , age and gender are coming to the surface , no longer silent within the context of loyalty to the African National Congress ( ANC ) . Each time the augur drills down into the soil 6-8 inches , the operator must lift it back up to the surface so the soil gathered in the spiraling coil will spin to the sides . When the heavy oil surfaces , the hydrocarbons are stripped off and recycled . Any solid surface , no matter how smooth , would tend to be roughened over time as a result of asteroid impacts .
