The invention relates to a preparation method of a petroleum degrading bacteria solid inoculant. The preparation method comprises the following steps: A, screening and domestication of the petroleum degrading bacteria; B, preparation of a seed culture solution; C, fermentation of the solid inoculant; and D, drying, pulverization, measurement and packaging of composted products. The petroleum degrading bacteria solid inoculant has the beneficial effect of improving the petroleum dissolution effect by taking a nonionic surfactantpolysorbate-80 (tween 80) as a solubilizer. The preparation method has the advantages that solid fermentation raw materials are easy to get and the process is relatively simple; and the solid inoculant contains a large amount of carbon and nutrient elements so as to provide more proper matrix for the growth of the bacteria, has strong affinity for the microorganisms, has immobilization efficiency, is capable of improving the competitiveness and degrading efficiency of the added microorganisms and indigenous microorganisms, and is convenient to transport and operate agriculturally and suitable for the large-scale in-situ biological remediation of the petroleum-polluted soil.

The bioactive compounds or microorganisms may include any one of or a combination of: a metabolite, an anti-microbial compound, an enzyme, a live microorganism, a fertilizer, a plant growth hormone, a preservative, a pesticide or an herbicide. Release of one or more bioactive compounds may be achieved in a timed and controlled manner.

A method is disclosed for treating superficial venous pathology in a patient. The method comprises the steps of: (a) percutaneously piercing a vein to be treated; and (b) directing intense pulse or laser light at the patient's skin predominantly within the area of skin manifesting physical, chemical and/or color changes caused by step (a). In a preferred method sclerotherapy is performed on the vein to be treated and then laser light is directed at the patient's skin substantially entirely within the area of skin manifesting the changes.

A compostable tie is disclosed. In some forms, the tie may have an aperture at the tail end sized and shaped to facilitate insertion of the tail into the head and use of the tie.

A process for eliminating the pollution of Pb, Zn and Cd to said and water by use of arabis paniculata features that the Arabis paniculata is planted in the polluted sol or water for absorbing Pb, Zn and Cd. When their concentrations in the plant reach a certain value, the plant on the ground is cut out and its root is retained for growing the plant no the ground and further cutting it out.

The invention relates to a method for rehabilitating uranium contaminated soil by use of a functional plant community. According to the method, broussonetia papyrifera and Ilex cornuta, and reed, Pteris multifida Poir and difformed galingale herb (herbaceous plants), which can enrich uranium in the soil are selected to construct a stable plant community with a function of in-situ repairing for uranium contaminated soil, wherein all plants in the plant community can enrich uranium in the uranium contaminated soil and can transport the uranium into an overground part of the plants, thereby achieving the purpose of rehabilitating the uranium contaminated soil. The method comprises the following steps of firstly, performing seed treatment and sowing; secondly, trimming and fertilizing; thirdly, harvesting; and fourthly, treating in a concentrating manner. The method does not need other auxiliary means and is capable of overcoming the disadvantages that the plant species structure is simple, the plant community is instable and easy to degrade, the maintenance cost is high, the plant diseases and insect pests are more and the ecological functions are at a low level when the single plant species is used for repairing the uranium contaminated soil in an existing method, the five plants have synergistic effect, and the repairing efficiency is improved remarkably compared with that of the method adopting the single plant species for rehabilitating the uranium contaminated soil.

The invention belongs to an image binarization processing method and relates to an adaptive threshold binarization method for two-dimensional barcodes. The adaptive threshold binarization method for the two-dimensional barcodes comprises the steps of 1.1) dividing a barcode image into a plurality of areas with the same size and calculating the average gray value of each area; 1.2) calculating the harmonic factor of each area and calculating the corresponding threshold by using the harmonic factor of each area; and 1.3) binarizing pixels in each area by using the corresponding threshold. The adaptive threshold binarization method for the two-dimensional barcodes has the advantages that not only can the speed of a local threshold binarization algorithm be improved, but also the threshold of each area can be dynamically and adaptively calculated, the blocking effect is enabled to disappear, the boundaries among areas can be well fused by using the harmonic factor of each area and the pseudo-boundary is well degenerated.
