Five milliliters of homogenates were mixed with 100 [micro]L of 0.04 M ammonium sulfamate, 200 [micro]L of 0.5 M lead acetate, and 2.5 mL of 20% (w/v) TCA and then made up to total volume of 10 mL with DW following incubation with 2 mL of 5 mM potassium ferricyanide in an ice under the dark for 60 min.
Studies were conducted on a series of steroidal sulfamates and the compound 17-diisopropylcarbamoyl - 1,3,5(10),16-estratetraen-3-yl sulfamate, also called KW - 2581, was recognised as a potent steroidal-based selective STS inhibitor.28 Using crude enzyme isolates from Chinese hamster ovary cells expressing human arylsulfatases, KW-2581 (Figure-2), was shown to exhibit high potency for STS inhibition with an IC50 of 4.0 nM.28 The compound also showed high selectivity, requiring 1000-fold greater concentrations to inhibit the other enzyme isolates.

For these low-till or no-till systems, scientists are using biotechnology to develop crop varieties with increased tolerance for herbicides .Non selective herbicides, toxic to all plants are used where complete control of plant growth is required.Other popular inorganic herbicides includes; ammonium sulfamate, carbon bisulfide, sodium chlorate, sulfuric acid solutions and solutions and formulations containing borate.
A number of other chemistries impart some degree of flame retardancy to polymers, including boron-containing compounds, melamine, and ammonium sulfamate. Development work continues on new flame-retardant materials, including polymer-clay nanocomposites, which may be effective at low addition levels, and silicon-based materials that form protective surface coatings during a fire.

Herbicides (amitrole, silvex, ammonium sulfamate, or 2,4-D acetic acid) can be used for control of large areas of poison ivy, oak, or sumac but are not species-specific and have the potential of killing surrounding plants or coming in contact with children or pets (Rietschel & Fowler, 2001a).
The deposits were plated on a laboratory scale using a mini barrel, with a 5 mm coating over the basic brass material, with and without an underplate (1-2 [micro]m nickel sulfamate or 1-2 mm bright acid copper) After plating, a proportion of the samples from each combination was annealed at 150[degrees]C for one hour.
Briefly, PAH is diazotized by sodium nitrate, and the excess sodium nitrate is neutralized by ammonium sulfamate. The diazotized PAH combines with N-(1-naphthyl)ethylenediamine dihydrochloride (NEDD) to form a purple-colored complex, which is quantified on a Technicon Auto Analyzer at 550 run.
The model is then coated with a conductive silver-based material and placed in a electroforming bath of nickel sulfamate where a thin nickel layer is plated over it.
There are several additional sulfonamide-based CAIs clinically available for the treatment of the aforementioned diseases, including topiramate, celecoxib (Celebrex), sulpiride (Dogmatil), sulthiame, valdecoxib, zonisamide, irosustat (COUMATE), and esterone sulfamate (EMATE) (Figure 5).
