A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

For the study discussed here, an in-situ evaluation was conducted of the East Bound (EB) US 80 pan-girder bridge (Figure 2) over a frontage road in Forney, Texas, through visual inspection and condition assessment.TxDOT recommended the inspections to catalog the current bridge condition in order to undertake future load rating and any strengthening that could be necessary.
In cancer/oncology: in situ means that malignant cells are present as a tumor but have not metastasized, or invaded beyond the layer or tissue type where it arose. This can happen anywhere in the body, such as the skin, breast tissue, or lung. For example, a cancer of epithelial origin with such features is called carcinoma in situ, and is defined as not having invaded beyond the basement ...
