Weakness, causes

The intermetallic compound layer shown in Fig. 10 are thought of FerTi and TiC[5]. This Tie is so called though is weak cause of the strength decrease [ 5]. 

Physical Very weak, caused by van der Waals forces. 

The first series of modifications featured in this chapter were all motivated by Good Intentions. In spite of creative ideas and considerable effort, these modifications failed because no one took the time to examine and expose their weaknesses. These undetected weaknesses caused undesired side effects.

While it is technically feasible to mine limestone, for the vast majority of limestone deposits there are major concerns over the risk of the mine roof collapsing as a result of weaknesses caused by faulting, jointing and bedding of the limestone. 

Common techniques neither allow the control of conformations at the nanometer scale nor provide a means to obtain specific individual conformations or to control the exact location of one maaomolecule with respect to another one. On the other hand, the manipulation of single macromolecules on solid substrates with the AFM tip may be used to assemble molecular systems that would not form spontaneously. Considerable progress was made in recent years using the AFM to manipulate nanoscopic objects across surfaces. For a macromolecule, a most critical issue is its interaction with the substrate, which is usually either too weak, causing the... 

Surface modification by polymers is an effective method of enhancing polymer-clay compatibility. There are two mechanisms for surface modification of clay minerals with polymers (i) physical adsorption and (ii) chemical grafting of functional polymers onto the clay surface. Physical adsorption modifies the surface properties of clay, but the structure of the clay mineral is preserved. However, the forces between the adsorbed molecules and the clay mineral might be weak, causing desorption. Grafting of functional polymers onto the surfaces of clay minerals provides stronger clay-polymer interaction and permits control... 

Qualitative ATs are used to identify product weaknesses caused by flaws in the product s design or manufacturing process. This is done by gradually increasing stresses until the product fails. The aim... 

Methods Muscle weakness was produced in one year old, female New Zealand white rabbits by injecting botulinum toxin type-A (BTXA) into the quadriceps musculature for times ranging from 1-6 months [7]. Contralateral limbs served as saline injected controls while other animals served as normal controls. Strength, muscle mass, muscle structure and knee histology (Mankin score) were evaluated to determine if muscle weakness caused joint degeneration. 

Purpose The purpose of this study was to test if VM weakness causes mal-tracking of the patella, thereby creating conditions for knee pain and degeneration.
