The choice of tracheostomy or cricothyrotomy to establish an airway depends on the patients’ clinical condition, for instance; cricothyrotomy should be preferred in patients with cervicothoracal injury or
dislocation who suffer from respiratory dysfunction. Furthermore; if a patient is under risk of hypoxia or anoxia due to a difficult airway, cricothyrotomy should be preferred rather than tracheostomy.”
“The study describes the effects of growth light conditions on growth and morphology of stokplants and LBH589 solubility dmso rooting ability of cuttings for mass clonal propagation of jackfruit (Artocarpus heterophyllus Lam.) without application of rooting hormone. Forty five days-old containerized stockplants were placed under three different levels of light: full
sun (Red to far red ratio 1.25), partial shade (R: FR 1; 60% of full sun) and deep shade (R: FR 0.4; 3% of full sun) for 45 days. Half of the stockplants growing in partial shade or deep shade were transferred to full sun for another 15 days and growth and morphology of shoots and rooting ability of cuttings were investigated. Growth and morphology of shoots and rooting ability of cuttings was significantly affected by the growth light conditions of stockplants. Internode number was significantly fewer, but internode length, leaf area and specific leaf area was higher in deep shade and deep shade to full sun regime. Leaf weight per unit area was decreased gradually, when sun-grown stockplants were transferred selleck to deep shade or partial shade and regained on returning them from the shade to full sun. The highest rooting percentage (100%), maximum number of root (6.3) and root dry selleck chemical weight (62 mg) per cutting was obtained from the cuttings of deep shade to full sun regime followed by deep shade and the lowest was in full sun regime without application of any rooting hormone.

“Systems externally reinforced by 123 bonded fibre reinforced polymers (FRP) are widely used in the retrofitting and strengthening of reinforced concrete (RC) structures. A drawback of the usage of this technique
lies on the uncertainty of the long term behaviour of those reinforcements. Researchers have paid heed to this aspect and a number of tests and alternative techniques have recently been described. An experimental programme developed to supplement work of the authors recently published and which focused on specimens not submitted to aggressive environments is described. The specimens used have the same geometry as in the previous paper, but they were exposed to salt fog cycles and dry/wet cycles with salt water for periods of 3000 h, 5000 h and 10,000 h. The interface of the glass fiber polymeric composite (GFRP)-to-concrete was characterized after the systems underwent such aggressive conditions. The GFRP wrap comprised of two layers and wet lay-up technique was used on its preparation and application.
