Abstract This paper reports the physical and mechanical properties of hand-woven carpets that have been put under static force. Two types wool fibres, from two parts Iran, were prepared to spin pile yarns for carpets. Each group fibres included both conventional tanned wool. Next, yarn counts, Nm = 4/2 6/2, spun different knot densities. After weaving, force their thickness variations measured plotted against time in logarithm scale. The resiliency carpets' piles, after eliminating force,...

An electromagnetic launcher can be used as an accelerator for yarn attached to a ferromagnetic projectile. As result, endures specific amount of tension. In addition the variables and type weft insertion system, parameters strongly affect velocity, its tension, consequently fabric quality. applicable model that represent relationship between input output this system is very useful predicting strike Therefore, in research 3D imitating launching was developed by finite element method. A coil...

There are different weft insertion methods in the looms. Electromagnetic launcher can be used to accelerate yarn which attached ferromagnetic projectile. In addition variables and system type, accelerator parameters strongly affect velocity, pulling force consequently fabric quality. Therefore, this research an experimental coil is implemented projectile velocity calculated by image processing for states of parameters. Studied voltage applied solenoid, initial position inside solenoid...

Cement composites (CC) are among the most widely used in construction industry, such as a durable waterproof and fire-resistant concrete layer, slope protection, application retaining wall structures. The use of 3D fabric embedded cement media can improve mechanical properties composites. calcium aluminate (CAC) accelerate production process CC further contribute to improving media. purpose this study is promote these cementitious by deepening knowledge their tensile investigating factors...

To investigate the effects of salicylic acid dipping and Aloe vera gel coating on shelf life post harvest quality table grapes (Vitis vinifera) cultivar Shahroudi, a factorial experiment was conducted basis randomized complete blocks design with three factors replicates in agricultural faculty Islamic Azad University 2014.The treatments were Salicylic (three levels 0, 1 2 mmmol-1 for 15 minutes) (four 10%, 15% 20% w/v) measurement traits 1st day, 30th day 60th after treatment berries.The...

The rose plant is one of the most widely sold and appreciated ornamental flowers throughout world. Vase life cut usually short. Hence, we studied effect sucrose combined with silver nitrate on (Rosa hybrida) flowers. study was carried out in a completely randomized design. Sucrose used concentration (5%w/v) four concentrations (0, 10, 20 30 ppm). Characters such as vase life, flower quality, water uptake, leaf chlorophyll, fresh dry weight were measured. Results showed that there not...

Ursolic acid (UA) is an important bioactive component in many traditional medicinal plants including pomegranate (Punica granatum L.) flower.This study presents the HPLC analysis of UA contents ten cultivars flower grown Iran. The fallen flowers were given each cultivar.Remarkable quantities found Iranian evaluated (21.736 to 15.119 mg/g). Lower determined (16.763 5.754 mg/g).UA values obtained from are very significant when compared with other sources UA. All analyzes suggested that...

There are different weft insertion methods used in the weaving machines. Electromagnetic launcher can be as accelerator to yarn which is attached ferromagnetic projectile. A validated finite element model predict system behavior accurately and faster than experiments. For optimization of new insertion, outputs should predicted by numerous states inputs. Thus, prediction less computation time very important. The present study an attempt examine use adaptive neuro fuzzy interface (ANFIS)...

Abstract In this study, we used an experimental design to investigate the influence of total draft, break distance between aprons (Clips) and production roller pressure on yarn quality in order obtain optimum drafting conditions for polyester viscose (PES/CV) blend yarns ring spinning frame. We PES fibers (1.4 dtex × 38 mm long) CV (1.6 spin a 20 Tex (70%)/CV (30%) ratio. When adjustment is not reasonable, controlling leading sufficient proper orientation structure produce high yarn....

This paper investigates about the simulation of warp tension variation in a weaving machine, based on mathematical and mechanical equations. To perform simulation, differential equation system was formed solved by numerical method. The results shown as curves variations back rail oscillation loom were compared with experimental obtained from measurement. result comparison showed good agreement between theoretical results.

In this paper, the application of image analysis to assess fabric wrinkle and abrasion resistance in order compare with experimental methods is described. Three samples cotton fabrics (plain) different finishing treatments were tested. present work, employing an appropriate lighting method, sample images captured by scanner, then prepared from processed MATLAB. Finally, number which evaluates each mentioned property was achieved. The results evaluation, revealing that data more precise than data.

Punica granatum L. is one of the oldest known edible fruits. Numerous chemical compounds have been isolated from pomegranate seeds, juice, and peels, which beneficial effects on human health. This study aimed to perform physicochemical morphological properties twenty-four genotypes various provinces Iran. Fifteen fruits each cultivar are collected at harvest maturity in normal ripening period for Iranian genetic collection Yazd, Five were randomly harvested four orientations tree,...

Natural preservatives such as herbal essential oils have potential ability for extending postharvest vase life of cut flowers. In this study, application effect cumin ( Cuminum cyminum L.) oil and 8-hydroxyquinoline sulfate on quality rose Rosa hybrida cv. Angelina) flowers were investigated. A factorial experiment with three levels each in different time after harvesting was conducted. Results showed that usage level hydroxyquinoline had significant effects attributes at the 0.05. The...

Cytotoxic effect of hydro-alcoholic extract pomegranate (Punica granatum L.) flowers and isolated ursolic acid on B16f10 melanoma cells

Carob moth is the most important pest for pomegranate production in Islamic Republic of Iran. Moreover, stored pomegranates decay by larvae due to penetration some microorganisms. Pomegranate farmers lose a huge amount annually because this pest, sometimes up 80% loss depending on area and cultivar. (Spectrobates ceratoniae) from Pyralidae family. It known as fruit neck worm Persian. In study, we surveyed research done worm, order recommend best method control pest. Finally, an integrated...
