Bonding social capital can also perpetuate sentiments of a certain group, allowing for the bonding of certain individuals together upon a common radical ideal.

This bonding breaks down the communication barrier, allowing the dog to understand Bart's commands, and consequently pass the obedience school.

A sort of coating, or primer, is used which both helps protect the glass filaments for processing / manipulation as well as ensure proper bonding to the resin matrix, thus allowing for transfer of shear loads from the glass fibers to the thermoset plastic.

His powers extend into the subatomic level ( insofar as the electromagnetic force is responsible for chemical bonding ), allowing him to manipulate chemical structures and rearrange matter, albeit this is often a strenuos task.

Year 2 students undergo a community experience trip to Malaysia, with the aim of bonding the batch and allowing students to experience farm life, community service and the wider world.

When Logan underwent the adamantium bonding, he went on a murderous rampage, allowing North and the others to escape.

The flux reduces surface tension at the juncture of the metals to accomplish metallurgical bonding, allowing the individual solder powder spheres to combine.

Starch gelatinization is a process that breaks down the intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites ( the hydroxyl hydrogen and oxygen ) to engage more water.

However the Red Ajah have also made a truce with the Asha ' man, allowing the bonding of Asha ' man to members of their Ajah, done by Mazrim Taim without the knowledge of Rand or his most powerful Asha ' man ally, Logain Ablar.

By heating the ground, cleaned feedstock, starch gelatinization takes place: the intermolecular bonds of the starch molecules are broken down, allowing the hydrogen bonding sites to engage more water.

In a few places cooperative programs between schools and employers in clerical work have shown the same possibilities for allowing the student, while still in school, to develop skills which are immediately marketable upon graduation.

In summary, while we stress that constructive engagement between anthropology and the military is possible, CEAUSSIC suggests that the AAA emphasize the incompatibility of HTS with disciplinary ethics and practice for job seekers and that it further recognize the problem of allowing HTS to define the meaning of “ anthropology ” within DoD.

The CQR design has a hinged shank, allowing the anchor to turn with direction changes rather than breaking out, while other plough types have a rigid shank.

Abhinavagupta likens it to the string of a jeweled necklace ; while it may not be the most appealing for most people, it is the string that gives form to the necklace, allowing the jewels of the other eight rasas to be relished.

Many also have firing ports allowing the infantry to fire personal weapons while mounted and improved armour.

" The book Plea Bargaining's Triumph: A History of Plea Bargaining in America published by Stanford University Press defines the plea as one in " which the defendant adheres to his / her claim of innocence even while allowing that the government has enough evidence to prove his / her guilt beyond a reasonable doubt ".
