Keyword density is an indicator of the number of times the selected keyword appears in the web page. But mind you, keywords shouldn't be over used, but should be just sufficient enough to appear at important places.

Screen resolution and device pixel ratio(DPR) check. DPR is a number that indicates how many physical pixels display device uses to form one logical pixel. DPR correlates with pixel density of the device or in other words the greater the DPR the sharper your display.

The Virtex™ UltraScale+™ FPGA VCU118 Evaluation Kit is the ideal development environment for evaluating the cutting-edge Virtex UltraScale+ FPGAs. Virtex UltraScale+ devices provide the highest performance and integration capabilities in a FinFET node, including both the highest serial I/O and signal processing bandwidth, as well as the highest on-chip memory density.

Vannaimei shrimp (Litopenaeus vannamei) is one of the most widely farmed shrimps in the world, Why it is favored by farmers is because of its fast growth and high economic value. However, vannaimei shrimp has high requirements for dissolved oxygen (DO) in water, especially in high-density farming mode. Reasonable and right selection of oxygenation equipment is crucial to improve survival rate, feed utilization rate and improve the economic value.
