The synthesis of nylon 4,T from tetramethylenediamine and a terephthalic acid derivative was studied in a two stepprocess: prepolymerization, followed by postcondensation in the solid state (4 h, m C ) . The prepolymers were prepared by the nylon salt method, ester polymerization method, interfacial method, and a low temperature solution method. A maximum qinh of 1.52 was obtained. From a solut...

Straw and animal manure are major organic waste materials from agricultural ecosystems. Different kinds of combined with straw (AM-S) may have varying effects on the decomposition, nutrient release, structural changes maize straw. Using Humic Cambisols soil as experimental area, decomposition characteristics under co-application were studied following nylon net bag landfill method. The experime...

The effect of whole lupin seeds (Lupinus albus cv Lublanc) at 120, 150 and 195 degrees C on in situ nitrogen degradability (Dg.N) was measured by the nylon bag technique using fistulated non-lactating Holstein cows. The N degradation was evaluated in nylon bags suspended in the rumen; heating the seeds at 120, 150 and 195 degrees C decreased the Dg.N value: 83.9, 72.9 and 53.0 respectively vs 9...

Synthetic versions of human derived kairomones can be used as baits when trapping host seeking mosquitoes. The effectiveness of these lures depends not only on their attractiveness to the mosquitoes but also on the medium from which they are dispensed. We report on the development and evaluation of nylon strips as a method of dispensing odorants attractive to the malaria vector, Anopheles gambi...

Microorganisms play a crucial role in litter decomposition terrestrial ecosystems. The leaf and fine root litters of Robinia pseudoacacia Linn., Quercus acutissima Carr., Pinus tabulaeformis Carr. densiflora Sieb. were analysed using the nylon bag method Illumina MiSeq high-throughput sequencing for amplification bacterial 16S rRNA V4–V5. We assessed effects species on community after one year’...

The aim of this experiment is to investigate the effects lactic acid bacteria and cellulase on fermentation quality, chemical composition, aerobic stability ruminal degradation characteristics mixed silage prepared with amaranth rice straw. Lactic were used as additives, four treatments follows: control group (CON, no additive), (LAB, additive amount was 5 mg/kg fresh matter), (CEL, 2 mg/kg) (L...
