Background and aim: Extraction of natural antioxidant compounds has recently attracted the attention of researchers. Almond is one of the native products of  Iran, which annually during the process of production , large volumes of waste is achieved. The aim of this study is investigating the impact of two parameters (time and ethanol percentage) on the extraction of phenol and ...

The dependence of acoustic backscatter variations on sediment grain-size distribution is examined using a combined analysis of 95 kHz side-scan data and approx. 300 grab samples from the New Jersey margin. We show that, under well-controlled circumstances, an unprecedented degree of correlation can be obtained between backscatter intensity and mean grain size. However, backscatter is disproport...

This study was conducted at College of Agricultural Engineering Sciences, University Sulaimani, Kurdistan Region-Iraq so as to investigate some nut traits in 10 bitter almond genotypes, capacity them release from dormancy and finally germination ability. Nut were calculated, stratified a sand medium 6 C refrigerator for 55 days, then they sown fine on August 22, 2021 29 days calculate percentag...

a bivoltine silkworm hybrid, ka x nb4d2 was treated with the juvenoid r394 (ethyl-9 cyclohexyl-3,7-dimethyl-2,4-nonadienoate) at a dose of 0.039 nl/larva at 24, 48, 72 and 96 h of 5th instar for silk yield improvement. treatment specific significant increase was observed in the cocoon and shell weight with no such marked variation in the shell percentage. notable changes were also seen in trait...

When examined under a high-resolution transmission electron microscope, carbon soot produced alongside buckytubes in an arc-discharge is found to contain a small percentage of flattened carbon shells. These objects are shown to be small graphite flakes which have eliminated their dangling bonds by terminating their edges with highly curved junctions. Ideal models for these structures are presen...

Cashew (Anacardium occidentale L.) has high demand in the world market due to wide range of applications. Cashew nut shell liquid (CNSL) has various range of biological properties. In the present study, an attempt was made to identify the phytochemicals present in the CNSL using solvent extract method. Antifungal activity of acetone, ethanol and ethyl acetate extracts on A. flavus, A. fumigatus...

in this study, thermo-mechanical nonlinear vibration of a polyethylene (pe) cylindrical shell embedded in an elastic foundation was investigated. the shell is reinforced by armchair carbon nanotubes (cnts) where characteristics of the equivalent composite being determined using mori-tanaka model. the elastic medium is simulated using the spring constant of the winkler-type,  . employing nonline...

in the present study, vibration of cylindrical laminates with different layers and angles were studied. in order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. laminates were assumed long enough so that plane strain state analysis in 2d can be used properly. in order to satisfy the boundary conditions, variables in terms of fo...

Cardanol is a natural and renewable organic raw material obtained as the major chemical component by vacuum distillation of cashew nut shell liquid. In this work a new sustainable procedure for producing cardanol-based micellar nanodispersions having an embedded lipophilic porphyrin itself peripherally functionalized with cardanol substituents (porphyrin-cardanol hybrid) has been described for ...
