某实施监理的工程项目，建设单位通过公开招标方式选择了勘察单位、设计单位、施工单位和工程监理单位，并与其分别签订了勘察合同、设计合同、施工合同和委托监理合同，在合同中约定了各自的工程质量责任和义务，现摘录合同中约定的部分质量责任和义务。 (1)设计单位应当将施工图设计文件报县级以上人民政府建设行政主管部门或...
For LCX-P lesion, wiring of the LCX main branch with Runthrough was performed, which was followed by wiring of intermediate artery with Fielder FC for side branch protection. POBA of the ostial lesion of the intermediate artery with 1.25x10mm balloon was performed, following with pre-dilatation...
If you want to experiment before investing in a dedicated macro lens with a focal length better suited to the style, you can get a reversing ring for a fraction of the cost. This allows you to mount a regular lens backward on your camera to create a macro effect. ...
When we’re talking about exposure in photography, a stop is a measurement of an exposure, depending on either the shutter speed, the ISO, or the aperture. To be specific, if you were to increase the exposure by one stop, you would be doubling the exposu
Interestingly, in April 1965 Weslake had filed a patent for a four-valve pent-roof combustion chamber with a projection between an intake and exhaust valve to promote axial swirl and a piston crown with a small recess beneath the spark plug location, and there is evidence of a very small ...
The light intensity at the zero order position is very intense; however, most of the light comes overlap to produce the rainbow- like spectrum, which is the irides- cence colon 9 49. CONCLUSIONS [Ed. For the complete dissertation by Liu, Shigley and Hurwit along with illustrations and ...
focal length by the shortest. For example, theSIGMA 18-35mm F1.8 DC HSM | Art and the8-16mm F3.5-4.5 are both examples of 2x zoom lenses: 35 divided by 16 equals 1.95, and 16 divided by 8 equals 2. (It is common practice to round to the nearest whole number or major fraction....
for astronomy. For most other producers eyepieces represent only a small fraction of the business. I’m sure Vixen, Pentax, Nikon etc have optical designers comparable to Al Nagler or Paul Dellechiaie, but those guys are small kogs in big machines. Good enough is good enough for them. ...
Such conditions could favour PF, a mechanism which causes the transport of contaminants to be associated primarily with a small fraction of the total pore space [21]. The transport of water and solutes is essential for the degradation of biodegradable fractions within the waste matrix, as this ...
