Nuclear microprobe at 2 MV Tandetron accelerator of Jozef Stefan Institute (JSI) was constructed in the year 2000 with the support of IAEA Technical Cooperation Project SLO/1/004. The measuring station is equipped with instrumentation for micro-Proton-Induced-X-ray-Emission (micro-PIXE), micro-Elastic Recoil Detection Analysis (micro-ERDA), micro-Nuclear Reaction Analysis (micro-NRA), Proton Be...

Valeriana officinalis is an important medicinal herb commonly found in Kashmir valley. This study forms an important preliminary step for in-vitro micro propagation of V. officinalis from breaking the seed dormancy, inducing rapid seed germination and its subsequent micro propagation. We investigated the influence of pretreatment of V. officinalis seeds with reduced temperature and light on see...

A novel rare-earth chloride seed was employed as a catalyst for growth of GaN nanoand micro-crystals on c-, aand r-plane sapphire. The ErCl3 seed on the substrate surface enhanced the growth rate and density of the GaN crystals. Distinctive green photoluminescence was measured, confirming that Er ions were active in the GaN matrix. This technique can be adapted to selectively grow GaN crystals ...

Abstract: Peganum harmala L. (Zygophylaceae) has been used in a variety of practical applications in medical science. Our objective in the current study was to determine the effects of the seed extract on Herpes simplex virus type 1 (HSV-1) replication in Vero cells. Different concentrations (100, 500, 571, 667, 800 and 1000 µg/ml) of the extract were examined. Experiments were carried ...

Seed coat permeability was examined using a model that tested the effects of soaking tomato (Solanum lycopersicon) seeds in combination with carbon-based nanomaterials (CBNMs) and ultrasonic irradiation (US). Penetration of seed coats to the embryo by CBNMs, as well as CBNMs effects on seed germination and seedling growth, was examined. Two CBNMs, C60(OH)20 (fullerol) and multiwalled nanotubes ...

Seeds are involved in the vertical transmission of microorganisms from one plant generation to another and consequently act as reservoirs for the plant microbiota. However, little is known about the structure of seed-associated microbial assemblages and the regulators of assemblage structure. In this work, we have assessed the response of seed-associated microbial assemblages of Raphanus sativu...

Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

background and aims. promoting remineralization is the ultimate goal of clinical prevention of caries lesion. the present in vitro study aimed to investigate the effect of grape seed extract (gse) on artificial enamel caries in primary human teeth. materials and methods. seventeen human sound primary incisors were sectioned mesiodistally. the tooth slices were placed in a demineralizing solutio...
