the nylon and nylon/lycra yarns were coated with electrically conductive polymers such as polyaniline and polypyrrole, via chemical polymerization process. electrical conductivity of the coated yarns was measured at variousstrain levels using two-point probe technique and their strain sensitivities were studied. the results showed that, electrical conductivity of the coated yarns decreased with...

Preparation of silver nanoparticle by using leaf extracts of Terminalia catappa, its deposition on Nylon fabrics, and the modification with an addition of HDTMS have been conducted in this research. The samples prepared in this study were nylon cloth (N0), nylon cloth silver nanoparticles (N1), Nylon cloth HDTMS (N2), Nylon cloth − silver nanoparticles − HDTMS (N3), and Nylon cloth HDTMS silver...

Codling moth ( Cydia pomonella ) is a major insect pest of apple Malus domestica ). If unmanaged, then codling can infest nearly all apples in an orchard, where the flesh-tunneling larva leave frass-laden tracks fruit. Insecticide-based management requires accurate application timing (typically based on adult and/or degree-day monitoring) and multiple spray applications. Both season-long commit...

Background: Excessive use of plastic bags has become a major problem in the worldwide causing irreparable damages to the environment and humans. The purpose of this study was to identify the individual and environmental factors associated with the use of plastic bags among the vendors of Hadishahr city, Iran. Materials and Methods: This is a cross-sectional study conducted on 400 vendors workin...

Blends of nylon-6 with polybutadiene were prepared with comparable morphology and different molecular weights of the matrix. These specimens were tested using the notched Izod impact test and the notched tensile impact test. An increase in molecular weight resulted in a shift of the brittle-to-tough transition temperature of 40°C to lower temperatures. In the notched tensile impact tests, espec...

Experiments in Niger assessed whether extreme environmental conditions including sunlight exposure affect the performance of triple-layer PICS bags in protecting cowpea grain against bruchids. Sets of PICS bags and woven polypropylene bags as controls containing 50 kg of naturally infested cowpea grain were held in the laboratory or outside with sun exposure for four and one-half months. PICS b...

We consider four different generalizations of bags (alias multisets). We first discuss Yager’s fuzzy bags having different sets of operations. It is shown that one is not a generalization of fuzzy sets but a mapping of them into fuzzy bags, since operations are inconsistent between the two, while the other includes fuzzy sets as particular cases. Third type is called real-valued bags which is s...

Este estudo teve como objetivo avaliar a dinâmica da decomposição fração foliar de Gliricidia sepium em diferentes sistemas uso e manejo do solo. A pesquisa foi desenvolvida três terra: sistema agroflorestal (SAF), mandala pastagem. O método empregado para quantificar fitomassa o bolsas nylon “litter bags”, coletadas cada sete dias, por um período 56 dias. Foram avaliados massa remanescente (g)...

Italian ryegrass (Lolium multiflorum Lam.) is a weed broadly found in fields cultivated with wheat and barley crops. Seed inputs into the soil before harvesting winter crops increase seed bank, ensuring survival. This study evaluated persistence of seeds subjected to burial depths over time. Experiments were carried out field for two years randomized block experimental design four repetitions. ...
