M. V. Klassen-Neklyudova The study found that online lectures in Nigeria during the COVID-19 pandemic were not effective as imagined; and therefore physical classes were preferred to online lectures. Online lectures were marred with many challenges like unreliable power supply, fluctuating internet and many others. Besides轻打 发表于 2025-3-23 15:44:21

Introductiontions when the external force is removed, the displacement being proportional to the stress. Apart from this proportional change (Hooke’s law), real crystals show nonlinear but reversible changes at fairly low stresses. This imperfect elasticity causes delay in the strain corresponding to a changed高兴去去 发表于 2025-3-24 09:06:51
Twinning with Change of Formhe displacement of cards in a pack. This division into macroscopic layers occurs in tension (Fig. 1) and also in response to compression, bending, torsion, and shear. This type of slip always occurs within the grains in a plastically deformed technical metal, rock, or other polycrystalline materiahankering 发表于 2025-3-24 12:37:29
Twinning without Change of Form of symmetry; two varieties of quartz crystal (right-and left-handed) occur in nature (Fig. 111, a and b). Quartz forms twins in accordance with the Dauphiné, Brazilian, and Japanese laws, and also Leydolt twins.争吵加 发表于 2025-3-24 16:07:15

Macroscopic Theory of Twinningading rate or to the temperature, which gave one reason to hope that twinning can be treated as a static problem corresponding to minimum potential energy. However, the problem cannot be solved generally within the framework of the macroscopic theory of elasticity; further simplifications are neededDEBT 发表于 2025-3-25 03:13:00
