    • Modifications to the extracellular polymeric substance, predominantly extracellular polysaccharide, of a biopolymer produced by Rhizobium tropici ATCC 49672 yield a stable dry salt transported more easily than a fluid or gel and more stable than either. The salt may be re-constituted with water on-site. Embodiments may be employed as a soil amendment for soil strengthening, reducing hydraulic conductivity, erosion control and dust control as well as a metal chelator for contaminant remediation. Based on comparison with dextran standards, an embodiment demonstrated a molecular weight over 511,000 D. Embodiments include a day salt that is precipitated from solution and in use is re-hydrated back to original form. When added to a sandy soil at 0.1% by dry weight, an embodiment decreased the hydraulic conductivity by three orders of magnitude. These properties make embodiments of the present invention an attractive, “green” alternative to petroleum-based synthetic polymers for such applications as rapid roadway construction and soil erosion prevention.
    • 对由根瘤菌根瘤菌ATCC 49672生产的生物聚合物的细胞外聚合物,主要是细胞外多糖的修饰产生比流体或凝胶更容易运输的稳定的干盐,并且比任一种更稳定。 盐可以在现场用水重新构成。 可以使用实施例作为土壤强化的土壤修正,降低水力传导性,侵蚀控制和粉尘控制以及用于污染物修复的金属螯合剂。 基于与葡聚糖标准的比较,一个实施方案证实了分子量超过511,000D.实施方案包括从溶液中沉淀并在使用中再次水合回到原始形式的日盐。 当以干重计0.1%添加到沙质土壤时,实施例将水力传导性降低三个数量级。 这些性质使得本发明的实施方案成为用于诸如快速道路施工和防止水土流失的应用的石油基合成聚合物的有吸引力的“绿色”替代物。

    • An additive for buffering a projectile trapping medium and spent projectiles trapped therein is a buffering compound formed as a low density foamed concrete block that will self-dispense via fragmentation or pulverization when subjected to incoming fire. The block combines at least one dry component selected from the group consisting of low solubility phosphate compounds, low solubility aluminum compounds, iron compounds, sulfate compounds, and calcium carbonate with a cementing material, water, and an aqueous based foam in substantially stoichiometric amounts. The aqueous based foam is added in a quantity sufficient to adjust the density of the resulting block to be non-buoyant without sinking in the projectile trapping medium. The additive may be employed in a projectile trapping medium to chemically stabilize the medium and environmentally stabilize projectiles trapped therein.
    • 用于缓冲抛射物捕获介质和被捕获的废弃抛射物的添加剂是形成为低密度发泡混凝土块的缓冲化合物,其在经受火灾时经由碎裂或粉碎而自分配。 该嵌段以基本上化学计量的量将至少一种选自低溶解度磷酸盐化合物,低溶解度铝化合物,铁化合物,硫酸盐化合物和碳酸钙的干组分与胶结材料,水和基于水的基础泡沫体组合。 添加的水性泡沫体的量足以将所得块的密度调节为非浮力,而不会沉入射弹捕获介质中。 添加剂可以用于抛射物捕集介质中以化学稳定介质并且环境地稳定被捕获在其中的射弹。

    • A modular bullet trap cover element generally includes a shell filled with a projectile trapping medium, preferably a mixture of a resilient granular ballistic medium and a hydrated super absorbent polymer (SAP) gel. The shell may be made of any of a number of fabric or polymeric materials. In embodiments, the shell includes at least two bags, an inner bag and at least one outer bag, each of which has an open end and a sealed end, connected to one another such that the outer bags may be inverted over the inner bag to cover at least a portion thereof. The modular cover element is formed by filling the inner bag with the projectile trapping medium and then inverting the outer bags to produce a multi-layer shell. In embodiments, the outer bags and inner bag are rotatably connected, permitting the outer bags to be rotated with respect to the inner bag such that bullet holes in the inner and outer bags no longer line up with each other. Several modular cover elements may be fixedly or releasably interconnected, preferably in a mattress-like arrangement, to form a bullet trap cover.
    • 模块化的子弹捕获器盖元件通常包括填充有弹丸捕获介质的壳体,优选地是弹性粒状弹道介质和水合超吸收聚合物(SAP)凝胶的混合物。 外壳可以由许多织物或聚合物材料中的任何一种制成。 在实施例中,壳体包括至少两个袋,内袋和至少一个外袋,每个外袋具有开口端和密封端,彼此连接,使得外袋可在内袋上翻转至 覆盖其至少一部分。 模块化盖元件通过用抛射物捕集介质填充内袋而形成,然后翻转外袋以产生多层外壳。 在实施例中,外袋和内袋可旋转地连接,允许外袋相对于内袋旋转,使得内袋和外包袋中的弹孔不再彼此排列。 几个模块化盖元件可以固定或可释放地互连,优选地以床垫状布置形成子弹捕获器盖。
