The mechanical properties of chrushed rock aggregates are greatly influenced by the petrographic characteristics of parent rock. The main objective of this study was to determine the relation between the petrographic characteristics of some volcanic and subvolcanic (silicate) rocks from Croatia, and ...

Members of Generation X, or Gen Xers, grew up in a time when there were more dual-income families, single-parent households, and children ofdivorcethan when boomers were growing up. Consequently, many Gen Xers were latchkey kids, returning from school to an empty home while their parents wer...
Industrial CT scanning combined with image processing technology canprovide a better way to explore 3 D distribution of rock fragments in soil. The content of rock fragments in soil is mainly determined by parent rocks. The surface soil(0-10 cm) of forest contains fewer rock fragments and more...
For example, distribution might indicate a nearby uphill source, or may represent the location of parent bedrock that has been worn away. Download: Download high-res image (422KB) Download: Download full-size image Fig. 13. Image mosaic of likely iron-nickel meteorite Lebanon (far) and ...
Granite residual soil has the residual structure of its parent rock. The ingress of free iron oxides into the soil during the process of weathering can easily form a secondary product3, which is then cemented or filled between soil particles to form a specific soil structure, referred to as ...
Poor parent–child relationships and harmful parenting practices can increase adolescent health-seeking behaviour50. Second, experiences of social-related stress often include having no friends or suffering from isolation. In our sample, a lack of social support may have led to a prolonged duration ...

In addition to the organic-rich shale in the Chang 7 Member (Ch7 shale) of the Ordos Basin, the shale hosted in the Chang 9 Member (Ch9 shale) is another source rock and potential unconventional target. However, there is a general lack of consensus on the features and potential of the...
