  • Publication number: 20120138449
    Abstract: The present disclosure relates to a method and process to remove the remaining sulfur in four types of Arabian crude oils (Arabian Heavy) (AH) and straight-run diesel (SRD) by ionizing radiation. Radiation-induced desulfurization is not feasible for absorbed doses up to 200 kGy. Most of the organically bound sulfur and/or elemental sulfur and hydrogen sulfide still exist in the irradiated samples. Sulfur removal from crude oil and straight-run diesel was achieved by combining gamma-irradiation with other physical/chemical processes (i.e. liquid/liquid extraction and oxidation) which provided a considerable levels of total sulfur reduction in the investigated products (AH and SRD). The best removal processes for Arabian heavy crude oil and straight-run diesel resulted in reducing total sulfur content up to 36% (AH) and 78% (SRD) corresponding to (liquid process/200 kGy) and (liquid process/200 kGy) for AH and SRD, respectively.

  • Patent number: 8173255
    Abstract: One of the major problems of commercial clean flame retardant materials is unstable mechanical properties because of high filler loadings. Clean flame retardant compositions having very low smoke and toxicity generation are invented by a method based on partial cross-linking of polymers. These composites are processed by routine thermoplastic extruder and do not use post curing system. Composition mainly contain 100 parts by weight (p/w) of resin (polyolefin or 100 p/w of polyolefin/ethylene propylene diene monomer rubber (EPDM rubber)), 90-150 p/w of non halogen content main flame retardants, 0.1-0.5 parts by weight of crosslinking agent, 1-20 p/w of auxiliary secondary flame retardant agents and 0.2-1.0 p/w of antioxidants. Clean flame retardant compositions use peroxide composite as a crosslinking agent and metal hydroxide composite as a flame retardant.

  • Patent number: 8108505
    Abstract: In a method for controlling channel access in wireless communications, an admitted time value is calculated for each access category in a station. The admitted time value is a maximum amount of medium time the station can use in a time period. A used time value is calculated for each access category in the station. The used time value is an amount of medium time used by the station. A determination is made whether the used time value is less than the admitted time value. If the used time value is less than the admitted time value, a frame with enhanced distributed channel access (EDCA) parameters is transmitted. If the used time value is not less than the admitted time value, a frame without the EDCA parameters is transmitted.

  • Publication number: 20120021103
    Abstract: The present disclosure relates to a process for removal of pesticide residues from aqueous solutions and food products by ionizing radiation. Standard pesticides concentrations recognized by international organizations as maximum residues limit (MRLs) were used as the targeted concentrations in both aqueous solutions and food products. Commercially known pesticides and recommended irradiation doses by International Atomic Energy Agency (IAEA) were selected for this investigation. Aqueous solutions and food products fortified with pesticide residues were subjected to selected doses of ionizing radiation. Radiation-induced removal of pesticide residues is generally greater in aqueous solutions than in food products. Ionizing radiation can reduce the residues of pirimiphos-methyl in potatoes, grapes and dates; malathion and cypermethrin in grapes to below MRLs at the recommended irradiation doses.

  • Publication number: 20110300360
    Abstract: NBT-PVA film dosimeters performance is affected due to high humidity levels. NBT-PVB film dosimeters with a relatively small effect of high humidity levels on its performance are invented. NBT-PVB film dosimeters are made by using alcoholic solution to dissolve both of NBT and PVB. The films are very useful for routine dosimeter in industrial radiation processing. A very high sensitivity NBT-PVB Radio-chromic film dosimeter is achieved due to high solubility of NBT dye in 2-methoxyethanol enabling the addition of very high concentrations of NBT dye in the film dosimeters. The dose response of conventional NBT-PVA dosimeter films are normally saturated after 50 kGy, while the invented composites of NBT-PVB dosimeter films demonstrated high dose range up to 100 kGy for high dose industrial use.

  • Publication number: 20110278039
    Abstract: An eco friendly radiation cross-linked composition is described that demonstrates excellent resistance to fire and high temperature along with good mechanical properties. The composition which is based on a blend of EVA with a LLDPE, is free of monomer such as vinyl co-agent for radiation cross-linking. The halogen free flame retardant composition is a mixture of 20 to 90% by weight of magnesium hydroxide (powder A) and 90% to 20% of powder B. Preferably the powder B is a double salt of magnesium carbonate and calcium carbonate and the magnesium hydroxide has a specific surface treatment. In addition, 0.5 to 5 parts of flame retardancy auxiliary agents are selected from talc, zinc borate or molybdate derivative. The chemicals used here reduce toxicity in the environment and do not release toxic chemicals to air and soil during fire. The flame retardant cross-linked polyolefin composition is particularly useful for insulating wires and cables.

  • Publication number: 20110233815
    Abstract: A tetrazolium bromide dye, e.g., 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), to be used as a high dose solution dosimeter is disclosed. The dose response of MTT solution dosimeter increases strongly with increase of absorbed dose up to 1 kGy. In order to increase the dose range and for ease of handling the present dosimeter as routine dosimeter, MTT-polyvinyl alcohol (PVA) film dosimeter is used. The dose response of MTT-PVA film dosimeters increases strongly with increase of absorbed dose up to 25 kGy. Polyvinyl butyral (PVB) as a polymer for making a film provides more stability at higher temperatures and humidity levels and less calibration is required. The dose response of MTT-PVB film dosimeters is effective with absorbed dose of up to 100 kGy.

  • Publication number: 20110180301
    Abstract: This invention focuses on improving mechanical properties without deteriorating flame retardancy in peroxide cross-linked and radiation cross-linked thermosetting clean flame retardant compositions. Optimal mechanical properties can be obtained by modifying the ratios of MAGNIFIN H10A/Ultracarb LH 15X in peroxide crosslinked or radiation crosslinked clean flame retardant composition. Higher tensile strength can be obtained by higher MAGNIFIN H10A content, and higher elongation at break can be obtained by higher Ultracarb LH 15X content. The invented compositions show excellent mechanical properties, flame retardancy, thermal properties, electrical properties and process ability for meeting the stringent specifications of wire and cable industry. Composition is made of 100 parts by weight of resin (polyolefin or 100 parts by weight of polyolefin/EPDM), 90-150 parts by weight of MAGNIFIN H10A/Ultracarb LH 15X as main flame retardants, 1-20 parts by weight of auxiliary secondary flame retardant agents and 0.2-1.
