BACKGROUND The ratio of the diameter of the main pulmonary artery (mPA) to the diameter of the aorta (Ao) on chest computed tomography is associated with diverse clinical conditions. Herein, we determined the functional and prognostic implications of the mPA/Ao ratio in Korean chronic obstructive pulmonary disease (COPD) patients. METHODS The study population comprised 226 chronic obstructive...

Latihan beban memberi manfaat meningkatkan performa kualitas kebugaran fisik atlet. sering terjadi pada atlet setelah melakukan proses latihan ialah delayyed onset muscle soreness (DOMS). DOMS rasa nyeri atlet/ orang biasanya terasa rentang waktu 24-72 jam pasca melaksanakan aktivitas beban. Riset/penelitian ini bertujuan untuk menganalisis status tingkatan dialami karena berlatih Sampel yakni ...

The pig is frequently used as an experimental model for studies of the pulmonary circulation, yet the branching and dimensional geometry of the porcine pulmonary vasculature remains poorly defined. The purposes of this study are to improve the geometric definition of the porcine pulmonary arteries and to determine whether the arterial tree exhibits self-similarity in its branching geometry. Fiv...

The length of the larynx was y4–5 mm. The cricoid cartilage formed a complete ring at the inferior aspect of the larynx and was fixed to the tracheal rings. The trachea was entered after passing through the cricoid cartilage and ended at the division into the right and left main stem bronchi at the carina. The bronchoscope was introduced through the larynx and directed to the trachea. The lengt...

this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

a brass vortex tube (vt) with interchangeable parts is used to determine the optimum cold end orifice diameter, main tube length and diameter. experiments were carried out to study the effects of operating pressure as well. it is shown that there is an optimum value for cold end orifice diameter, which is equal to 4mm and there is an optimum value for cold and hot exit temperature difference at...

Morphological characters such as main stem length (cm), number of branches per plant, leaf length (cm), number of leaves per main stem, number of leaflets per leaf, diameter of main stem (mm), pods / main stem and seeds / pod as well as agricultural herbage yield (t ha), dry matter yield (t ha), seed yield (t ha), crude protein (%) were investigated in Trakya, during the 1999-2002. The maximum ...
