A board connector used in a printed circuit board assembly and includes a shell, a pin and an elastic member. The shell has a chamber therein and a hole on a surface thereof. The pin is configured to accommodate in the chamber, wherein at least one part of the pin protrudes out of the shell via the hole. The elastic member is configured to locate in the chamber. The pin is located between the surface of the shell and the elastic member.

A method for systematically controlling rapid proliferation of cyanobacteria cells in lakes in spring is described. The method applies physical, biological and chemical methods in an integrated and synergistic manner and includes using flexible enclosures to close a control water area and using modified soil to adsorb and settle algal cells; coupling four technologies including algae control by fish, algae control by biological floating islands, algae inhibition by plants and algae control by microorganisms; and using HOto kW algae and using 40% FeCl+CaCOand 50% Ca(NO)to treat sediment. The method establishes a complete system for physical, chemical and biological control of algae, forms joint control of exogenous contaminants, endogenous contaminants and cyanobacteria, integrates physical, biological and chemical methods and optimizes systematic methods that are used synergistically.

A vent filter and a Radio Remote Unit having the vent filter. The vent filter includes a first member including a first body having a ventilation path extending through the first body, an inner wall constituting a ventilation hole which is communicated with the ventilation path, and an outer wall constituting a gap between the inner wall and the outer wall. The vent filter also includes a second member including a second body and at least one enclosure wall protruding out from the second body, wherein at least one of the at least one enclosure wall is located outside the outer wall and surrounding the outer wall. Both the inner and outer walls have at least one first groove at an end and each of the at least one enclosure wall has at least one second groove at an end.

The present invention discloses the Synthesis and application of MOFs/natural polymers composite beads adsorbents. To overcome the drawback of MOFs, in an embodiment, both novel MOFs/sodium alginate (MOFs/SA) and MOFs/chitosan (MOFs/CS) composite beads were prepared and characterized. Each composite beads include one or more of MIL-101 (Cr), MIL-100 (Cr), MIL-53 (Al), MIL-100 (Al), NH-MIL-101 (Al), UIO-66, ZIF-8, ZIF-68, ZIF-67, and ZIF-9-67 nanoparticles. Adsorption of anionic contaminants onto the two composite beads was investigated and compared with pristine sodium alginate beads (SA) and chitosan beads (CS). The novel MOFs/SA beads all exhibit much higher adsorption capacity than SA beads; the novel MOFs/CS beads all exhibit much higher adsorption capacity than CS beads, which indicates that MOFs played a key role in the adsorption of anionic contaminants. The porous composite beads disclosed herein and related methods and devices may be used in adsorption technologies.
