Two kinds of epoxy resin, a soft one with rubber-based additives and an ordinary hard one, are used as electrical insulators airtight sealants in penetrations nuclear power plants (NPPs). Knowing how they behave under adverse environments is important for the safe operation NPPs. In this regard, we gave artificial thermal ageing treatment to two resins by heating them air at various temperature...

angiogenesis, formation of new blood vessels, play an important role in some diseases such as cancer and its metastasis. using angiogenesis inhibitors, therefore, is one of the ways for cancer treatment and prevention of metastasis. medicinal plants have been shown to play a major role in the treatment of a variety of cancers. in this direction, cytotoxic and angiogenic effects of oleo gum resi...

During the course of investigations on the metabolism of hexosamines in animal tissues, absorption spectra of the color produced in the hexosamine method of Elson and Morgan (1) revealed the presence of interfering chromogens. Similar types of interference have been noted in studies on the jelly coat of sea-urchin eggs (2), Neurospora (3), and pineapple plants (4). Hexosamines were found to pro...

In folk medicine pinenes are used internally for expelling kidney stones. Terebinth is prepared using the oil filtered from oleoresin (turpentine). The homeopathic remedy is primarily used to treat problems of the kidney as well as the urethra. This homeopathic remedy was proved way back in the 19th century. Pine resin mostly contains diterpene and acids of abietic and pimaric types. αand β-pin...

ABSTRACT The search for alternatives that enable the improvement of soil water retention capacity should focus on a better use by cultivated plants. This study aimed to evaluate effect natural tree resin rates and irrigation levels cotton (intermediate cycle) wild radish (short crops. Two experiments were conducted in completely randomized design, 5 × factorial arrangement, with three replicati...

Food plants are those that have one or more parts products can be used in food, such as: roots, tubers, bulbs, rhizomes, stalks, leaves, shoots, flowers, fruits and seeds even latex, resin gum, to obtain edible oils fats. Many called "weeds" because they grow among the cultivated plants; however, species with great ecological economic importance. These plants, PANC'S (Unconventional food plants...

Background: There is a technique in the industry called resin procedures like resin coating. For example, epoxy resin is injected to repair cracks in concrete of 0.2 mm or larger. In addition, a casting product can be strengthened when resin is injected to fill in a blowhole. A vacuum can be utilized to allow the resin to penetrate into every corner. In this study, we investigate whether bondin...

This study aimed to evaluate the tensile and transverse bond strength of chairside reline resins (Tokuyama Rebase II, Mild Rebaron LC) to a thermoplastic acrylic resin (Acrytone) used for non metal clasp denture. The results were compared with those of a conventional heat polymerized acrylic resin (Paladent 20) and a thermoplastic polyamide resin (Biotone). The failure sites were examined by sc...

This in vitro study performed elemental analysis of the ions absorbed into the salivary coat covering the surfaces of S-PRG resin blocks and assessed the adherence of Streptococcus sanguinis and Streptococcus mutans to these saliva-coated S-PRG resin blocks. Elemental analysis of ions absorbed into the salivary coat of resin blocks exposed to the saliva was performed using an inductive coupled ...
