Abstract: A method utilizing a humic acid substance for renovating and afforsesting slag is provided. A humic acid substance may be utilized for passivation, adsorption, reduction, chelation and immobilization of harmful heavy metal elements in slag, for example, Cr, As, Cd, Ni, Pb, Ba, Hg, Co, Se, Ag and Be, and aggregating the slag, thereby detoxifying the slag and producing artificial earth. The artificial earth may be used in combination with a carrier bacterial fertilizer to continuously produce the active humic acid substance, achieving an effect similar to the combination of blood transfusion and blood production, thereby forming a high-quality artificial soil.

Abstract: Providing a environment-friendly and in situ immobilized method of renovating heavy metal contaminated soil with humic acid substance, comprising: while the heavy metal contaminated soil being pulverized, adding humic acid substance into the soil according to weight ratio 5-20:1 of the humic acid substance to the total heavy metals contained in the soil, then aging the soil for more than 24 hours after the pulverization process; 2) adding 1-3 parts by weight of semi-coke bacterial fertilizer to 100 parts by weight of the water-stable granular structures, and mixing uniformly.

Abstract: Adverse optical effects from a cover glass used to cover a display of an information handling system may be reduced at an imaging area that covers an imaging device, such as a video camera. An anti-reflective coating may be applied at the imaging area over an anti-glare coating to improve light transmission and contrast at the imaging device.

Abstract: An electrical connector for electrically connecting with a chip module includes an insulating body having a bottom wall, multiple rows of terminals located in the bottom wall for electrically connecting the chip module, and a carrier for carrying the chip module to the insulating body. Two first side walls extend from two opposite sides of the bottom wall upward, and two second side walls extend from the other two opposite sides of the bottom wall upward. There are a first gap between the first side wall and a most peripheral terminal corresponding to the first side wall, and a second gap between the second side wall and a most peripheral terminal corresponding to the second side wall. The first gap is greater than the second gap. The carrier has a buckling portion, received in the first gap, and for buckling a bottom surface of the chip module.
