1. Iron Nitrate Modified Cotton and Polyester Textile Fabric Applied for Reactive Dye Removal from Water Solution
In this work, we investigated the use of cotton scraps in natura and modified with iron nitrate, in the adsorption of one of the main water contaminants of the textile industries, the reactive black dye. Special attention was paid to the appropriate destination of the spent adsorbent, in compliance with the precepts of the circular economy. Cotton and polyes

2. Ramularia leaf spot effect on yield and fiber quality of cotton submitted to fungicide application
RESUMO A mancha de ramulária (MR) é a principal doença do algodoeiro no Brasil e uma das principais causas de redução na produtividade da cultura. A doença causa desfolha, reduz a capacidade fotossintética e provoca abertura precoce de capulhos. Devido a importância da doença para o algodão e da carência de publicações nessa área, neste se aval

3. Diallel analysis and inbreeding depression in agronomic and technological traits of cotton genotypes
ABSTRACT Cotton provides about 90% of the world textile fiber, and is one of the crops of greater industrial relevance. The objectives of this study were to estimate the inbreeding depressionand the genetic effects involved in the control of the agronomic andfiber quality traits in F1 and F2 generations and to identify promising hybrids for obtaining superio

4. Genetic gains in agronomic and technological traits of elite cotton genotypes
ABSTRACT The objective of this work was to estimate the predicted genetic gains with the simultaneous selection of agronomic and technological traits from elite cotton lines using selection indexes. Data from the evaluation of 36 elite lines were evaluated in three trials located in Apodi-RN in 2013 and 2014 and Santa Helena, GO, Brazil in 2013, in a randomi

5. Artificial neural networks classify cotton genotypes for fiber length
Abstract Fiber length is the main trait that needs to be improved in cotton. However, the presence of genotypes x environments interaction for this trait can hinder the recommendation of genotypes with greater length fibers. The aim of this study was to evaluate the adaptability and stability of the fibers length of cotton genotypes for recommendation to the

6. The influence of heat treatment on the quality of screen printed textile substrates
ABSTRACT During exploitation, textile products printed with screen printing technique are quite often exposed to various influences, one of which is a heat treatment- firstly during the production process and later on when ironing. Heat is simultaneously affecting deposited colorants (ink) on the surface of the substrate material, as well as textile fibers i

7. Statistical Modelling and Optimization of Fermentation Medium for Lincomycin Production by Streptomyces lincolnensis Immobilized Cells
ABSTRACT Response surface methodology was used to optimize lincomycin production by Streptomyces lincolnensis NRRL ISP-5355 in submerged fermentation. Screening of fermentation medium components to find their relative effect on lincomycin production was done using Plackett-Burman design. Malt extract, dextrin, soluble starch and (NH4)2SO4 were the most signi

8. Selection of cotton genotypes for greater length of fibers
Abstract In cotton breeding programs, it is necessary to identify genotypes with predictable behavior on the length of fibers, and which are responsive to environmental variations, in specific or broad conditions. The aim of this study was to employ the methodology of mixed models for simultaneous selection of cotton genotypes with greater length of fibers,

9. Characterization of Fibers from Pineapple's Crown, Rice Husks and Cotton Textile Residues
Fibers from pineapple's crown (PCF), rice husks (RH) and cotton textile residues (RTF) were characterized by SEM, X-ray diffraction, FTIR and thermogravimetric analysis. Moisture content, water absorption, density and the distribution of the diameter of the fibers were also evaluated. RTF showed cylindrical microstructure with smooth surface, PCF showed cell

10. Population growth and within-plant distribution of the striped mealybug Ferrisia virgata (Cockerell) (Hemiptera, Pseudococcidae) on cotton
Population growth and within-plant distribution of the striped mealybug Ferrisia virgata (Cockerell) (Hemiptera, Pseudococcidae) on cotton. The striped mealybug, Ferrisia virgata (Cockerell) (Hemiptera, Pseudococcidae), is a widely distributed and polyphagous pest species, which naturally occurs on cotton plants in Brazil. This study evaluated the establishm

11. Within-plant distribution of cotton aphid (Hemiptera: Aphididae) in cotton cultivars with colored fibers
Nós descrevemos a distribuição vertical e horizontal do pulgão do algodoeiro Aphis gossypii Glover dentro da planta de algodão (Gossypium hirsutum Linnaeus), em dois cultivares com fibras coloridas (BRS Safira and BRS Rubí) ao longo do seu desenvolvimento. Medidas de dinâmicas de populações e distribuição de A. gossypii nas plantas de algodão for

12. Estudo comparativo da cicatrização entre os fios poliglecaprone, algodão e poliglactina em anastomoses de intestino delgado de cães / Polyglecaprone, cotton and polyglactin sutures in intestinal anastomoses of dogs, a comparative study
In this study was evaluate, macroscopically and microscopically, the healing process of intestinal anastomoses in dogs using polyglecaprone 25, polyglactin 910 and cotton sutures. Twenty mongrel dogs, weighting from 9 to 16 Kg were submitted, under general inhalatory anesthesia, to three small intestine anastomoses. The animals were divided into four groups,
