Indonesia, India and China are among the world’s major producers of gums and resins. India is the leading producer of lac, Guar Gum and Gum Karaya. Gum and resin are important minor forest produce and are a source of livelihood for tribals residing in forest, sub-forest, desert and mountain areas. Some state governments have banned the tapping of resins and gums as the method for tapping are destructive in nature. To give proper attention to these important export oriented minor forest products, ICAR has approved a Network Project on Harvesting, Processing and Value Addition of Natural Resins

Natural resins, gums (NRGs) are the most extensively used and traded non-timber forest products (NTFPs) other than directly consumed products. The present field-based study reports the natural gum, resin and gum-resin yielding plants and the specific parts from which the products extract from plants by local people in Telangana, India. The result of the present report reveals ninety plant taxa belong to 63 genera and 23 families that predominated by Fabaceae with 36 plant taxa, followed by Malvaceae (12 spp.), Combretaceae, Anacardiaceae and Rubiaceae (5 spp. each), Arecaceae (Palmae) (4 spp.)

The results indicate that high resin viscosity is best achieved by using a high U:F molar ratio (1:2) and conducting the reaction at 90°C. Several basic components produced in urea-formaldehyde reac

Methods currently used to isolate this fraction, generally lack reproducibility and yield impure and strongly overlapping fractions which do not reflect the actual group-type distribution in the liquid fuel.

Some major resin and oleo-gum-resin containing plants, such as myrrh, ginger, Capsicum sp. and Podophyllum sp., among others, are presented along with their pharmacological properties. Information on the structures, biosynthesis and medicinal properties of cannabinoids, which are derived from Cannabis sativa, are highlighted.

This study was carried out during the ICR conservation project involving two of the mural paintings of the Saint Peter and Paul’s hypogeum in Matera. Retouching mural paintings preserved in such a peculiar environment as hypogea is not an ordinary operation. In these contexts, relative humidity approximating to 100% makes hygroscopic materials less durable, favouring biological growth on them. In addition, severe climatic conditions can lead to a fast degradation of retouching materials.

The secondary emission electron (SEE) gun, in which a beam is generated by ion bombardment of the cathode, offers an attractive option for pulsed laser applications. With this type of cold cathode gun, a dc voltage is applied to the cathode and the electron beam is controlled by modulating the source of ions in which resides a ground potential. This design greatly simplifies the electron gun power system. A SEE gun system has recently been developed which provides a 150-kV, 5- × 150-cm2 beam at current dens
