1. Production of Mannitol by Fungi from Cotton Dust

Cotton dust associated with high pulmonary function decrements contains relatively high levels of mannitol. In this study, cotton leaf and bract tissue and dust isolated from cotton leaf tissue were examined by optical microscopy, scanning electron microscopy, and capillary gas chromatography. Alternaria alternata, Cladosporium herbarum, Epicoccum purpurasce

2. Soluble sugars and starch accumulation on cotton plant leaves affected by cotton leafroll dwarf virus.

The cotton blue disease, a main cotton pest in Brazil, is caused by a luteovirus, named Cotton leafroll dwarf virus (CLRDV) or Cotton vein mosaic virus (CVMV). Symptoms include shortening of internodes and stunting. Luteoviruses have been reported to cause carbohydrates accumulation in infected plants. The aim of this research was to verify if soluble sugars

3. Alternativas para o cultivo do algodoeiro herbáceo em plantio direto no Cerrado.

RESUMO: O experimento , instalado em um Latossolo Vermelho-Amarelo muito argiloso, teve o objetivo de obter melhor alternativa para o cultivo do algodoeiro herbáceo (Gossypium hirsutum L. r. latifolium Hutch) em plantio direto em condições de sequeiro no Cerrado. O delineamento experimental foi o de blocos casualizados com quinze tratamentos e quatro repe

4. Cotton Closure as an Aeration Barrier in Shaken Flask Fermentations

Oxygen transfer through a cotton plug follows Fick's law of diffusion. The apparent diffusion constant decreases as the density of cotton packing is increased. Formulas are derived which relate oxygen transfer to cotton-plug dimensions. Calculations indicate that the dimensions of a cotton plug can affect both the maximal oxygen uptake rate and the gas compo

5. Processing and Properties of PCL/Cotton Linter Compounds

Biodegradable compounds of poly(ε-caprolactone) (PCL)/ cotton linter were melting mixed with filling content ranging from 1% to 5% w/w. Cotton linter is an important byproduct of textile industry; in this work it was used in raw state and after acid hydrolysis. According to the results of torque rheometry no decaying of viscosity took place during compoundi

6. Byssinosis: The Acute Effect on Ventilatory Capacity of Dusts in Cotton Ginneries, Cotton, Sisal, and Jute Mills

Studies of ventilatory capacity change in small groups of employees during a shift in a cotton mill and in three cotton ginneries in Uganda, a sisal factory in Kenya, and a jute mill in England, have demonstrated that an effect is produced by the dust in the cotton mill and in a very dusty ginnery but not in two other less dusty ginneries. No significant eff

Impact of the cotton plant tricome on the cotton leafworm Alabama argillacea (Lepidoptera: Noctuidae) and his predator Podisus nigrispinus (Heteroptera: Pentatomidae) / Impacto da pilosidade do algodoeiro sobre o curuquerê Alabama argillacea (Lepidoptera: Noctuidae) e seu predador Podisus nigrispinus (Heteroptera: Pentatomidae)

The impact of cotton plant trichomes on the cotton leafworm Alabama argillacea (Lepidoptera: Noctuidae) and its predator Podisus nigrispinus (Heteroptera: Pentatomidae) was studied in the laboratory and greenhouse. Initially, the development, survival and reproduction of A. argillacea in cotton plants with high and low trichome density were studied showing a

10. INTERACTION BETWEEN THE COTTON BOLLGARDTM, THE TWOSPOTED SPIDER MITE, Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) AND ITS PREDATORY MITE Phytoseiulus macropilis (BANKS) (ACARI: PHYTOSEIIDAE). / INTERAÇÃO ENTRE O ALGODOEIRO BOLLGARDTM, O ÁCARO RAJADO, Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) E O PREDADOR Phytoseiulus macropilis (BANKS) (ACARI: PHYTOSEIIDAE)

Cotton plants have been genetically transoformed with genes from the bacterium Bacillus thuringiensis Berliner (Bt) which confers the plant resistance against certain lepidopoteran pest species. The Bt-cotton carries genes that express the toxin Cry1Ac. This creates new interactions in the agroecossystems encouraging researches to answer the questions about

11. Experimental Infection of the Cotton Rat Sigmodon hispidus with Rickettsia rickettsii1

Studies of experimental infection of the cotton rat, Sigmodon hispidus, with the virulent Sheila Smith (R type) and the avirulent Si 7 (U type) strains of Rickettsia rickettsii were undertaken to evaluate the role of this native wild mammal in the ecology of Rocky Mountain spotted fever. The Sheila Smith strain, which was highly lethal for guinea pigs, was n

12. Histamine Liberation by Cotton Dust Extracts: Evidence Against its Causation by Bacterial Endotoxins

The recently stated hypothesis that histamine liberation by cotton dust extracts is caused by endotoxins from gram-negative bacteria contained in cotton was studied experimentally in various animals. It was shown clearly that such amounts of endotoxin as were found in cotton dust did not give rise to histamine liberation which was provoked by extracts from c
