The experiment was carried out in a greenhouse, using 3.7 kg pots filled with a dystrophic red-yellow Latosol of medium texture. The experimental design was randomized, with treatments divided into a 4 x 6 factorial: four doses of potassium (0; 200; 400; 600 kg ha(-1) K2O) and six alternative sources of nutrients (breccia, ultramafic, biotite schist, phlogopite, and mining

and Chapada by-products), with four replications. Content and accumulation were determined for potassium (K), copper (Cu), zinc (Zn) and nickel (Ni) in the lettuce shoots, and from these data two indices were calculated for the efficiency of potassium as a fertilizer. The application of increasing values of alternative sources of nutrients promoted improvements in nutrition and increases in lettuce yield. The efficiency of potassium fertilization decreased with the increase in values of potassium this website CUDC-907 taken from alternative nutrient sources, with the mining by-products and the ultramafic being superior to the other sources. Crushed silicate rocks and mining by-products can therefore both be used as fertilizer in organic and conventional production systems.”
“Aim: To understand how surgeons arrive at a decision in the complex and

controversial field of radiotherapy in rectal cancer by identifying which variables are important in this decision and to assess the influence of age, training, area of practice and access to radiotherapy on decisions in this click here field. Methods: A self-administered survey was distributed to 150 members of the CSSANZ. They were asked

to rank the importance of 33 variables considered when making decisions to use radiotherapy in the treatment of rectal cancer. The responses were assessed for association of surgeon age, area of practise or access to radiotherapy with decisions in this field. Results: A hierarchy of variables was produced which showed tumour characteristics had the highest average importance, higher than that attained by patient characteristics and side effects. There were subtle but statistically significant differences in the ranking of importance when surgeons were grouped by age, site of subspeciality training, site of practise and availability of radiotherapy service. Conclusion: This study identifies a hierarchy of variables used in decision making concerning radiotherapy in rectal cancer treatment, which may be used in heuristic decision making. Decisions on using radiotherapy are influenced by age, site of practise, site of training, and the presence of radiotherapy on site. (C) 2014 Surgical Associates Ltd. Published by Elsevier Ltd.
