The effects of seed coating treatment on yield and yield components in some cotton (Gossypium hirsitum L.) varieties
The use of delinted cotton seeds in cotton planting instead of fuzzy cotton seeds has spread recently. Cotton planting area of the world was 32,150,000 ha in 2003 - 2004. Approximately 45 - 50% of the planting seed in the world is delinted. This signifies that nearly 16,000,000 ha cotton area is planted by delinted cotton seed. In this study, coating fuzzy cotton seeds is proposed as an alternative to delintation. Coating makes fuzzy cotton seeds more suitable for the pneumatic spacing planter. Also, unlike delintation, sulphuric acid is not used for coating and this eliminates the problems associated with its usage such as seed loss, pollution and threats to human health. The results show that the cultivation of coated cotton seeds has no disadvantage regarding the agronomic and technological characteristics of cotton seed; coating may even improve the characteristics of the seeds. Also, no significant difference exists in terms of yield. Hence, seed coating has the potential to expand organic cultivation of cotton, as the coated seeds can be easily planted with pneumatic spacing drills and as organic seed procurement would be provided with the seed coating method.Keywords: Fuzzy cotton seed, seed coating, yield componentsAfrican Journal of BiotechnologyVol. 9(34), pp. 5523-5529, 23 August, 201
Temperature dependence of the Raman-active phonon frequencies in indium sulfide
Cataloged from PDF version of article.The temperature dependence of the Raman-active mode frequencies in indium sulfide was measured in the range from 10 to 300 K. The analysis of the temperature dependence of the A(g) intralayer optical modes show that Raman frequency shift results from the change of harmonic frequency with volume expansion and anharmonic coupling to phonons of other branches. The pure-temperature contribution (phonon-phonon coupling) is due to three- and four-phonon processes. (C) 1999 Elsevier Science Ltd. All rights reserved
An improved method of supercharged transposed latissimus dorsi flap with the skin paddle for the management of a complicated lumbosacral defect
OBJECTIVE: Treatment of nonhealing wounds of lower back often poses a powerful challenge. We present one of the first
report of treatment of a lumbosacral defect with a supercharged latissimus dorsi flap with the skin paddle.
CASE REPORT: We report a case of a 59 yearold man with myeloma of the sacral spine who underwent radiotherapy and chemotherapy and subsequently, laminectomies and placement of hardware for ongoing paresis and spine instability. Then, he developed an open wound and osteomyelitis of the spine with culture positive tuberculous granulomas. After multiple surgical debridement, he presented to our service and was treated with a single stage debridement followed by the performance of a latissimus dorsi musculocutaneous flap based on paraspinal perforators and supercharged.
RESULTS: This solution, allowed for augmentation of blood flow to the muscle with the inferior gluteal artery, provided coverage of the defect resistant to the pressure, and simplified post-operative management of the patient.
CONCLUSIONS: Alternative treatment options, including free tissue transfer, posed difficulties in finding suitable recipient vessels near the defect, in inserting the flap so as to restore its original length without compromising blood flow, and in postoperative care of the patient. Treatment of a lumbosacral defect with a supercharged latissimus dorsi flap with the skin paddle may represent a milestone procedure for complicated lower spine wounds
Fourier transform infrared spectroscopy as a novel approach for analyzing the biochemical effects of anionic surfactants on a surfactant-degrading acrobacter butzleri strain
Cataloged from PDF version of article.Anionic surfactant-biodegrading capability of an Arcobacter butzleri strain was analyzed under aerobic conditions. The A. butzleri isolate displayed efficient surfactant-biodegrading capacity for sodium dodecyl sulfate (SDS) at concentrations of up to 100 mg/L in 6 days, corresponding to 99.0% removal efficiency. Fourier transform infrared spectroscopy was applied to observe the effects of varying concentrations of SDS on the biochemistry of bacterial cells. Results suggest that protein secondary structures were altered in bacterial cells at sufficiently high SDS concentrations, concurrent with SDS biodegradation
Diabetic Foot Due to Anaphylactic Shock: A Case Report
Introduction: Diabetic foot is a clinical disorder, which is commonly seen in patients with diabetes mellitus. It is also the major cause of below knee amputation in the world. There are many underlying causes such as neuropathic, ischemic, and infectious causes for diabetic foot. Local or systemic complications may develop after snake bite.
Case Presentation: We reported a very rare case, involving a 78-year-old male admitted to the Emergency Department, who developed anaphylactic shock and diabetic foot after the snake bite.
Conclusions: Reviewing the literature, this is the second reported case of snake bite associated with diabetic foot
Preconcentration with 1-Nitroso-2-naphthol Complexes on Dowex MWC-1 Resin: Determination of Cu and Zn at Trace Level in Drinking Water Samples by ICP-AES
Abstract: In this study, copper(II) and zinc(II) were quantitatively determined in drinking water using ICP-AES after preconcentration. For this purpose, the water samples were treated with 1-nitroso-2-naphthol to form metal complexes on Dowex MWC-1 resin. Prior to the sorption process, the column was treated with a chelating resin Dowex MWC-1 and the column was prepared by passing buffer solution at different pH values. These columns were used for the transportation of water samples through the resin at the flow rate of 2.00 mL min -1 . The effluents were then analyzed by ICP-AES using standard addition method. The effect of pH, amount of resin, ligand concentration and eluent type were investigated. The detection limit for Cu(II) and Zn(II) were found to be 2.78 µg L -1 and 6.34 µg L -1 respectively (RSD.'s <%5). It would be concluded that the determination of copper(II) and zinc(II) in drinking water was simple, fast and reliable using this technique
