Abstract The research aims to evaluate the response of rice plant fertilization with NPK, NPK Organic fertilizers and spraying nano-vanadium nano-selenium in some growth yield indicators (Anber 33 cultivar).A field study was conducted Al-Tali’a district (41 - Al-Hussainiya, south Hilla city) Babylon province Iraq, for period from 15/6/2021 26/11/2021.The experiment according a randomized comple...

The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...

in order to study of nutritional role of silicon nano-particles on physiological characteristics of minituber potato production an experiment was carried out as  factorial based on randomized complete blocks design with three replications in hydroponic culture at ferdowsi university, mashhad. treatments were included particle size of sodium silicate (nano and micro) and concentrations in levels...

PURPOSE This in vitro study investigated the fracture resistance of endodontically treated premolars restored using silorane- or methacrylate-based composite along with or without fiber or nano-ionomer base. MATERIALS AND METHODS Ninety-six intact maxillary premolars were randomly divided into eight groups (n = 12). G1 (negative control) was the intact teeth. In Groups 2-8, root canal treatme...

In order to evaluate the effect of medium and spraying calcium nano-fertilizer on quality of cut gerbera flowers, an experiment was conducted as factorial in completely randomized design with 7 media and 3 calcium nano-fertilizer concentrations with 3 replications. The media included cocopeat + perlite (1:1), peat moss + perlite (1:1), mushroom compost + perlite (1:1), peat moss + cocopeat + pe...

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

The communication security is set up by registration during the first beliefand get in touch between two human beings. The safety codes among them aregenerated and the records are blocked by these protection codes if the end user is not therequired one. On the other hand, the unlocked records are transmitted if the required enduser is confirmed by the feedback brain signals via the comments min...

One possible interesting way of designing a scaffold for bone tissue engineering is to base it on trying to mimic the biophysical structure of natural extracellular matrix (ECM). This work was developed in order to produce scaffolds for supporting bone cells. Nano and micro fiber combined scaffolds were originally produced from starch based biomaterials by means of a fiber bonding and a electro...

Abstract Environmental space threats are becoming more critical as they affect the optical, thermal, and electrical properties of reinforced fiber polymeric-based materials in spacecraft. Three different Nano-particles Alumina (Al 2 ,O 3 ), Multiwall Carbon Nanotubes (MWCNT), Reduced Graphene Oxide (RGO) were added to epoxy matrix then by bidirectional carbon plain form fiber/epoxy hand lay-up ...
