Subcritical water was applied to alter pumpkin polysaccharides, and the properties and cancer prevention agent action of pumpkin polysaccharides were examined. Medicines at different temperature prompted changes in the rheological and emulsifying properties of pumpkin polysaccharides. Medicines proficiently debased pumpkin polysaccharides and changed the atomic weight appropriation. Diminishes in natural consistency, thickness normal sub-atomic weight, and obvious consistency were likewise noticed, while the actuation energy and stream conduct files expanded. The temperature of treatment impacts the straight viscoelastic properties and cancer prevention agent action of pumpkin polysaccharides. Pumpkin polysaccharides arrangement treated by showed the most noteworthy emulsifying action and cell reinforcement movement, which was presumably because of a more extensive sub-atomic mass dissemination and additional diminishing finishes uncovered after treatment. Filtering electron microscopy showed that treatment changed the microstructure of pumpkin polysaccharides, bringing about the openness of greater surface region. Our outcomes recommend that treatment is viable ways to deal with adjust pumpkin polysaccharides to accomplish further developed arrangement properties and cell reinforcement movement.

Improved oil recuperation processes are notable for their proficiency in augmenting oil creation; nonetheless, the choice of the most reasonable technique to take on for explicit field applications is testing. Thus, this section presents an outline of various methods right now applied in oil fields, the potential open doors related with these procedures, key mechanical progressions to direct the decision‐making system for ideal pertinence and efficiency and a concise survey of field applications. Oil supplies go through series of creation stages named essential optional and tertiary recuperation strategies. These stages assign creation from a supply in a consecutive example with various recuperation efficiencies over the long haul. Oil recuperation is dominatingly affected by narrow number at the minuscule scope and versatility proportion at the plainly visible scale number signifies the proportion of thick powers to interfacial pressure powers where addresses fine is consistency of dislodging liquid; and is the interfacial strain between the uprooted and the dislodging liquid. It has been tentatively shown that an expansion in fine number declines remaining oil immersion.

The amount, rate of formation and radiation-chemical yields of molecular hydrogen obtained from the process of radiolysis under the influence of gamma quanta (60Co, P=9.276 rad/s, T=300 K) in the nano-SiO2/H2O system with a mass of particle of m=0.2 g and size of silicon particle of d=20÷60 nm by changing of water mass (m=0.01÷0.8 g) were studied. It was found that the rate of formation and radiationchemical yield of molecular hydrogen determined by increasing the mass of water • decrease by 10 times for water, • increase by 8 times for nano-silicon dioxide, • for common system, increase at the values of water mass of 0.01 gm H2O 0.2 g, have the maximum at mH2O =0.2 g and decrease at 0.2 g< mH2O 0.8 g.
