In Portugal., the study of mechanical pruning in olive orchards began 1997. Trials were carried out traditional orchards, and obtained results revealed that can contribute to reduction costs without a yield. 2005, authors started an evaluation high-density orchards. The trial was organised randomised, complete block design, with three replications. Four treatments compared: T1—manual pruning, u...

Conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. In the recovery system, super-critical an CO2 is employed as the working fluid operating in a Brayton cycle. Low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes th...

Combined heat and power (CHP) systems in both power stations and large plants are becoming one of the most important tools for reducing energy requirements and consequently the overall carbon footprint of fundamental industrial activities. While power stations employ topping cycles where the heat rejected from the cycle is supplied to domestic and industrial consumers, the plants that produce s...

Continuous intercostal nerve blockade was used to provide analgesia after cholecystectomy. The blockade was maintained by the insertion of a single extradural catheter into an appropriate intercostal space and by "topping-up" with local anaesthetic on demand. Of the patients studied, 92%, and 76%, required no additional analgesia in the first 24 h and first 48 h following operation, respectivel...

THE FIRST step in producing a satisfactory crop of tobacco is to use good seed that is true to type. The grower often can save his own seed to advantage, if he wants to. Before topping is done, he should go over the tobacco field carefully to pick out desirable seed plants. When he has decided on the ideal type of plant, he should select the plants that conform to this type for producing seed. ...

In spite of the remarkable progress made by the medical science in the last century, the effectiveness of tuberculosis (TB) treatment and vaccination has remained less than satisfactory. This has placed a very high burden on the public health systems of the third world. Annually, about 1.5 million deaths are attributed to TB [1]. The number of new cases seems to be on the rise, topping 9 millio...

is added to grapefruit pulp the pulp acts as a bland filler and makes an apple pie. If peach is added it makes a peach pie. Citric acid, sugar and peel oil give excellent orange, grapefruit and tangerine jams. A little' peel oil, sunset yellow, No. 6 and sugar makes a good ice cream mix. Add more sugar and you have a good sundae topping. Cake fillings were made from the jams but they gave troub...
