The harmonic constants of diurnal constituent [ (K1+O1)/2],semidiurnal constituent (M2) and shallow water constituent (M4) are obtained. The results produced by the combined model are in better agreement with the observed ones than those produced solely by the original 2-D model. The combined model gives much more reliable results for tide-induced residual water level and current.展开更多

However, giventhe interest of the authors insight, it appears misleading when related to that discussed in our report which was clearly referred toother patients＇ profiles. Indeed, they described a case with a singleperipheral nodule in the right lung and a single liver metastasesin segment 5. This uncommon situation （less than 2% of patientsaccording to the LiverMetSurvey registry [2]）, is obviouslya more than reasonable indication for a mini-invasive approach.However, our patients received surgery for complex oncological involvementof the liver： as described, this means large and/or multiplelesions, in contact or invading the hepatic veins at caval confluence.For such conditions we have introduced original surgicalapproaches [3,4]： in such conditions we would select a J-shapedthoracophrenolaparotomy for the liver per se [5]. This incision forsuch complex conditions other than allowing the liver clearance in a single operation rather than in staged approach [6], allows justin case the removal of lung nodules. Therefore, we thank again theauthors for their interest to our report, and furthermore we congratulatefor the original management of the shared clinical case.However, the condition recalled by the authors is related to a scenariooncologically and surgically at the opposite side of that discussedin our paper and for that somehow suggesting a comparisonis misleading.展开更多

The combined capacity of renewable energy generation reached 100 MW at the end of 1994. And it is planned a combined capacity of 1236 MW will be targeted for the year 2000.展开更多

Objectives: The work was conducted to determine the effects of the peeling with lactobionic acid, corundum microdermabrasion, and a combined technique of both means on sebum secretion in acne vulgaris patients. Methods: The peeling with 50% lactobionic acid, the corundum microdermabrasion, and the combined technique were applied to 45 female patients divided into three groups of fifteen people each. Every one treatment was given five times in two week intervals. The measurements of sebum secretion were done within the T- and U-zones using Sebumeter SM15 (Courage & Khazaka, Germany). The last (sixth) measurement was performed two weeks after the last treatment. Results: Decrease in the level of sebum secretion was found during second or third measurement. Two weeks after the last treatment, the biggest decrease in the level of sebum secretion was observed in the patients treated with lactobionic acid, followed by those treated with the combined method. Conclusions: Treatments consisting of the peeling with lactobionic acid, corundum microdermabrasion, or the combined technique, brought significant decrease in the level of sebum secretion. The biggest decrease was observed in the patients treated with lactobionic acid, which being structurally similar to α-hydroxyacids exerts exfoliating properties. The combined method was also effective, because of increased skin penetration of the active ingredients, resulting from the abrasion of stratum corneum during the corundum microdermabrasion. The corundum microdermabrasion alone was the least effective approach.展开更多

Among these stenoses, the number of complicated tracheal lesions, where a resection and anastomosis is not successful or not applicable, is also increasing significantly. These acute situations often need to be managed by a combined surgical technique. The present paper is dedicated to this topic;the management of combined surgical and endoscopic technique in case of complicated long tracheal stenosis.展开更多
