    • Magnesium ammonium phosphate (struvite), suitable for use as a slow-release fertilizer for example, is produced by mixing animal manure with a pre-specified amount of a magnesium-rich compound. A pre-specified amount of an enzyme, such as an urease or uricase, is added to the resultant mixture. The temperature and pH of this mixture are maintained within a pre-specified range to facilitate precipitation of the magnesium ammonium phosphate. Optionally, the enzyme-supplemented mixture may be inoculated with a pre-specified amount of bacteria, such as Bacillus sphaericus, Bacillus globisporus, or Bacillus fusiformis, or a species of Bacillus identified as Bacillus sp. SB1. This bacteria-supplemented mixture is then allowed to incubate for about 14 days to form struvite. Alternatively, a pre-specified amount of phosphatase, an enzyme promoting the formation of phosphate from phosphorus-rich organic compounds, may be added with the first enzyme to further accelerate the process and increase the yield of struvite crystals.
    • 通过将动物粪便与预先确定量的富含镁的化合物混合,可以生产适合用作缓释肥料的磷酸铵铵(鸟粪石)。 向所得混合物中加入预定量的酶,例如脲酶或尿酸酶。 该混合物的温度和pH值保持在预先确定的范围内以促进磷酸铵铵的沉淀。 任选地,补充酶的混合物可以用预先指定量的细菌,例如球形芽孢杆菌,全球球孢子杆菌或梭状芽胞杆菌或称为芽孢杆菌属的芽孢杆菌种类接种。 SB1。 然后将该细菌补充的混合物孵育约14天以形成鸟粪石。 或者,可以加入预先规定量的磷酸酶,一种促进磷富含有机化合物形成磷酸酶的酶,以进一步加速该方法并提高鸟粪石晶体的产率。

    • A system and method for dewatering particulate materials employs an improved dewatering probe generally including a single non-conducting pipe having a plurality of holes or slots, an anode mounted on the pipe adjacent one end of the pipe, and a cathode mounted on the pipe adjacent the opposite end of the pipe. The pipe serves as both a sonde for mounting the anode and cathode and as a well for extracting water that collects around the outside of the pipe and flows into the interior of the pipe through the holes or slots via gravitational and electro-osmotic forces. A pump may be used to extract both collected water and accumulated electrolytic gases from the pipe's interior. In embodiments, an array of guide electrodes is mounted on the pipe in addition to the anode and the cathode in order to deflect the major current flow out into the body of surrounding particulate materials. The guide electrodes also facilitate rapid depolarization of the probe. An array of probes according to the present invention may be employed as a system to dewater a volume of particulate.
    • 用于脱水颗粒材料的系统和方法采用改进的脱水探针,其通常包括具有多个孔或槽的单个非导电管,安装在邻近管的一端的管上的阳极和安装在管的相邻的管上的阴极 管道的相对端。 管用作安装阳极和阴极的探头,以及用于抽出围绕管的外部收集的水的井,并通过重力和电渗流通过孔或槽流入管的内部。 可以使用泵来从管道内部提取收集的水和积聚的电解气体。 在实施例中,除了阳极和阴极之外,引导电极阵列安装在管道上,以便将主电流流出物流入周围的颗粒材料的主体。 引导电极还有助于探针的快速去极化。 可以使用根据本发明的探针阵列作为对体积的颗粒进行脱水的系统。

    • 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.

    • A continuous covered area, such as a sidewalk or patio, is formed by vertically interlocking tessellated components. One embodiment, termed PORTAPAVE™, achieves this interlocking via an array of uniquely configured two-sectioned pavers. Each paver has a first section of a first shape and a second section of a second shape impressed upon the first section and bonded together. In one embodiment, first sections of pavers in an installed bottom layer form a cavity between them having the same shape as the second section of a paver that is inverted onto the pavers of the bottom layer, thus providing a top layer. Each inverted paver in this top layer is fitted to interlock in that cavity formed between the un-inverted pavers in the bottom layer. Also provided is a method of making the components, e.g., pavers, and a method of installing them.
