The article will be focused on methods of chemical modification of NR and the use of improved traditional fillers such as carbon black (CB) and silica. Modification reactions include epoxidation, hydrogenation, and grafting vinyl monomers onto NR molecules. Some methods of surface modification of NR film were also reviewed. Thanks to modification the NR degree of unsaturatiton is decrease that leads to its enhanced aging resistance.

Kidney transplantation (KT) is the most obvious method of treating a patient with end-stage renal disease. In the early stages of KT, urine production is considered a marker of successful reperfusion of the kidney after anastomosis. However, there is no clear conclusion about the relationship between initial urine output after KT and 1-year renal function. Thus, we investigated the factors that affect 1-year kidney function after KT, including urine output.

Magnetic amidoximated nanocomposites based on a combination of chitosan and magnetic laponite RD were prepared and examined for the removal of Cu2+ from aqueous solutions. Magnetic laponite RD was prepared by an in situ method. In order to prepare magnetic amidoximated nanocomposites, acrylonitrile was grafted to chitosan in the presence of magnetic laponite RD. Then the nitrile pendants on magnetic chitosan-g-polyacrylonitrile/laponite RD (mChtioPANLap) were converted to amidoxime groups.

This work reports the synthesis and properties of a new membrane based on polyvinyl chloride (PVC) grafting with polyacrylic acid (PAA) using argon (Ar) plasma. The membranes of PVC were synthesized by solutioncasting method, where PAA was deposited as an ultrathin film onto PVC using dielectric barrier discharge at atmospheric pressure with Ar gas. The surface characteristics and chemical composition of the modified membranes were analyzed by water contact angle, scanning electron microscopy, and Fourier transform infrared spectroscopy.

The propagation of the hibiscus may be carried out with cutting and grafting. Stem cutting and cleft grafting are the most important method of vegetative propagation. The cuttings treated with high concentration of IBA, performed the best in rooting and survival percentage, whereas, the mist house growing condition was found effective in increasing the success rate of the cuttings.

An experiment was conducted during 2019-20 at INS farm -1, SOADU, Bhubaneswar in order to study the variation regarding morphological parameters, plant physiological condition, and survival of the grafts, when different varieties were used as scion material. The experiment consists of five different popular mango varieties namely cv. Mallika, cv. Arka Neelachal Kesari, cv. Arka Puneet, cv. Amrapalli, and cv. Dussehri as scion varieties. One local cv. “Ganga” cultivar was used as rootstock for all the scion varieties and was also used as one of the scion (control).
