The effect of extended laundering on cotton fabric treated with Dimethylol dihydroxyethyleneurea (DMDHEU) easy care finish was investigated and the fabric characterised by crease recovery performance and the Kawabata Evaluation System for Fabrics (KES-F). The KES-F results indicated that the mechanical handle properties of the DMDHEU treated cotton fabrics were affected by both the levels of application of the DMDHEU easy care finishes and the stress relaxation of the fabrics in aqueous conditions.

The surface chemical analysis and bulk analysis were conducted for fibres regenerated from waste garments and treated with iodine solution. The aim was to assess the fibre accessibility by the iodine solution and ascertain the location of the reagent within the fibres. X-ray Photoelectron Spectroscopy (XPS) analysis indicated that the fibres regenerated from indigo dyed waste denim garments (ReCell-Denim) had a relatively high accessibility by the iodine solution compared to the standard lyocell, ReCell-1 and ReCell-2 fibres. With the exception of ReCell-Denim, the standard lyocell, ReCell-1 and ReCell-2 fibre’s iodine sorption values correlated well with the percentage crystallinity. The high accessibility of the ReCell-Denim fibres was attributed to the presence of the positively charged nitrogen from the indigo dyes that improved the substantivity of the fibres to the iodine solution. The iodine sorption of the fibres is relatively higher in the bulk compared to the fibre surface.

Multipurpose cactus pear plant with great potential as a source of food and livestock faced a threat from Dactylopius spp in different countries. Specifically, D. coccus is an important pest damaging significant areas in Tigray-Ethiopia. Using pest-resistant cultivars is an important element of an integrated pest management strategy, and studying the mechanisms of resistance is vital. It can be chemical or physical such as oxalate crystals and other cladode characteristics. Cladode features of six cultivars (three O. ficus-indica, two O. cochenillifera, and one O. robusta) were examined for resistance to D. coccus in a completely randomized design (CRD) with three replications. ‘Rojo Pelón’ (O. ficus-indica), ‘Robusta’ (O. robusta), and ‘Bioplástico’ (O. cochenillifera) are resistant cultivars;and ‘Atlixco’ and ‘Chicomostoc’ (O. ficus-indica) and ‘Nopalea’ (O. cochenillifera) are susceptible. Cultivars showed a significant difference in cladode weight in g, and cladode length, cladode width, and cladode thickness in cm, where cladode thickness was higher in ‘Rojo Pelón’ followed by ‘Robusta’. Calcium oxalates number per mm was higher in ‘Bioplástico’ (20.7 ± 2.08) followed by ‘Robusta’ (18.9 ± 2.31) and ‘Rojo Pelón’ (15.9 ± 0.34);and similarly, epidermis thickness found higher in ‘Bioplástico’ (0.21 ± 0.032) and ‘Robusta’ (0.19 ± 0.014), but similar with ‘Rojo Pelón’ (0.18 ± 0.026). However, cuticle thickness didn’t show a difference among cultivars. Cladode thickness, calcium oxalate number, and epidermis thickness had positive correlations with resistance. These results demonstrate that calcium oxalate number and epidermis thickness might have a positive role in D. coccus resistance in O. ficus-indica. This feeding-barring role and the insect-plant interaction need to be studied.

Piatã grass (Brachiaria brizantha cv. Piatã) is a tropical grass cultivating in pasture production system. The aim of this study was to evaluate the effects of nitrogen levels (0, 125, 250, 375 and 500 kg·N·ha-1) on structural characteristics and forage production of Piatã grass. The experiment comprised of twenty grass parcels arranged in randomised completely casualties design. This study was carried out between November of 2007 and April of 2008, with 175 experimental days. A quadratic effect (P ·m-2 at a nitrogen dose of 357 kg·ha-1. A quadratic effect (P ·ha-1·year-1?for nitrogen levels of 411 and 384 kg·ha-1, respectively. However, a considerable portion of forage production obtained by nitrogen addition occurred from stem production. The productions of green leaf blade dry matter, tiller density, leaf blade length and leaf blade index are all variables related to structural aspects and pasture quality, with all attaining their highest values at a mean nitrogen application level of 380 kg·ha-1.
