This research is designed to help and offer hold up to complete the requirements of aged and disable in a home. The control approach and the tone approach are used to manage the house appliances. The major organize system implementation in technology of wireless to offer distant contact from a phone Internet Protocol connectivity for access and calculating strategy and appliance remotely. The planned system no need a committed server PC with value of parallel systems and offers a new communication-protocol to observe and control a house environment with more than just the switch functionality. To express the possibility and efficiency of this system, devices like as lights switches, power plugs, and motion-sensors have been included with the planned home control system and supply more security manage on the control with low electrical energy activate method. The rank of switches is corresponding in all this control system whereby all user interfaces indicate the real time existing status. This system planned to manage electrical-appliances and devices in house with reasonably low cost of design, user friendly interface, easily install and provide high security. Research community generally specified that the network "Reconnaissance Attacks" in IPv6 are usually impossible due to they will take huge challenge to carry out address scanning of 264 hosts in an IPv6 subnet."It being deployed of IPv6 shows that it definitely enhances security and undermines the probability". This research of the IPv6 addressing-strategies at present utilizes and planned a new strategy and move toward to "mitigate reconnaissance attacks".
New fossil remains of family Cervidae from the Dhok Pathan Formation (Middle Siwaliks) of Pakistan
Abdul Ghaffar,Muhammad Akhtar,Muhammad Akbar Khan,Muhammad Khaled Siddiq 한국지질과학협의회 2015 Geosciences Journal Vol.19 No.4
Five mandibular fragments from the Early Pliocene of Dhok Pathan and Hasnot (Middle Siwaliks) are described and discussed. Detailed comparison of the studied material with already known and described species of family Cervidae from the Siwaliks allow us to refer this material to genus Rucervus and species Rucervus cf. simplicidens. The material described here also extends the stratigraphic range of this genus from Upper Siwaliks to Middle Siwaliks. The fossil material described from the Early Pliocene, is thus important to indicate the older stratigraphic range as described earlier from the Siwalik continental deposits.

Here in, we demonstrate facile fabrication of silver and palladium nanoparticles in dual responsive poly(Nisopropylacrylamide- co-2-Acrylamido-2-methylpropane sulfonic acid) microgel with temperature- and pH-dependent catalytic potential. Palladium-based catalyst showed better catalytic efficiency as compared to silver-based catalyst for degradation of Rhodamine-B and P-Nitrophenol in aqueous medium under the same set of reaction conditions. The responsive nature of the microgel was found to be useful to tune the catalytic activity of the as-prepared catalysts, and reduction rate was enhanced with the pH and temperature elevation of the reaction medium; however, the increasing trend was slowed in the volume phase transition region of the microgel. Under a specific set of reaction conditions, the reduction of Rhodamine-B was as fast as 0.968 and 0.571 min1 when catalyzed with palladium and silver based catalysts, respectively. The hydrodynamic radius of the particles of microgel support was found to be in the range of 65- 180 nm when pH and temperature of the medium were varied in the range of 2-12 and 25-45, respectively. The estimated diameter of silver and palladium nanoparticles fabricated in the microgel support under the same set of reaction conditions was 9-15 and 7-11 nm, respectively.

Multi-responsive poly(N-isoprpylacrlamide-methacrylic acid-acrylamide) [P(NIPAM-MAA-AAm)] copolymer microgel was prepared by free radical emulsion polymerization. Silver nanoparticles were fabricated inside the microgel network by in-situ reduction of silver nitrate. Swelling and deswelling behavior of the pure microgels was studied under various conditions of pH and temperature using dynamic light scattering. A red shift was observed in surface plasmon resonance wavelength of Ag nanoparticles with pH induced swelling of hybrid microgel. The catalytic activity of the hybrid system was investigated by monitoring the reduction of p-nitrophenol under different conditions of temperature and amount of catalysts. For this catalytic reaction a time delay of 8 to 10min was observed at room temperature,which was reduced to 2 min at high temperature due to swelling of microgels, which facilitated diffusion of reactants to catalyst surface and increased rate of reaction.

We investigated the effect of crosslinking density of poly(N-isopropyl acrylamide-co-acrylic acid) micro-gels on catalytic activity of silver nanoparticles fabricated hybrid microgels. Multiresponsive poly(N-isopropyl acryla-mide-co-acrylic acid) microgels with 2, 4, 6 and 8 mole percentage of N,N-methylene-bis-acrylamide were synthesizedby emulsion polymerization. These microgels were characterized by dynamic light scattering and were used as mi-croreactors to synthesize silver nanoparticles. Hybrid system was characterized by ultraviolet-visible spectroscopy. Thecatalytic activity of hybrid microgels with different crosslinker content was compared by studying the reduction of p-nitrophenol as a model reaction. Kinetics of reaction was monitored by spectrophotometry. The value of the apparentrate constant decreases from 0.568 to 0.313 min−1, when content of crosslinker are increased from 2 to 8 mole percent-age respectively. This decreases in value of apparent rate constant is due to increase in diffusional barrier offered byhigh crosslinking of polymer network at high mole percentages of N,N-methylene-bis-acrylamide.
