U-Bike merupakan sebuah prototipe awal dari self-powered indoor trainer bike Universitas Multimedia Nusantara (UMN), yakni sebuah sepeda olahraga dalam ruangan yang dapat digunakan sebagai penghasil listrik dan dapat dimanfaatkan sebagai energi alternatif. Penelitian ini bertujuan untuk membangun protoripe awal dari self-powered indoor trainer bike yang dilengkapi dengan instrumentasi dasar sepeda olahraga seperti perhitungan kecepatan, monitoring detak jantung pengguna, sampai dengan penghasil energi listrik dari energi kinetik. Pengujian yang dilakukan telah menunjukkan bahwa sistem dari generator sepeda dapat digunakan untuk mengisi daya pada baterai aki, speedometer yang mempunyai akurasi rata-rata 98%, pengukuran pulse rate yang mempunyai keakuratan rata-rata 97.5%, serta energi yang digunakan oleh instrumen tidak menguras cukup banyak sehingga sepeda ini cocok sebagai penghasil energi alternatif.

AbstractTo explore the effectiveness of microgravity simulated by head-down bed rest (HDBR) and artificial gravity (AG) with exercise on lung function. Twenty-four volunteers were randomly divided into control and exercise countermeasure (CM) groups for 96 h of 6° HDBR. Comparisons of pulse rate, pulse oxygen saturation (SpO2) and lung function were made between these two groups at 0, 24, 48, 72, 96 h. Compared with the sitting position, inspiratory capacity and respiratory reserve volume were significantly higher than before HDBR (0° position) (P< 0.05). Vital capacity, expiratory reserve volume, forced vital capacity, forced expiratory volume in 1 s, forced inspiratory vital capacity, forced inspiratory volume in 1 s, forced expiratory flow at 25, 50 and 75%, maximal mid-expiratory flow and peak expiratory flow were all significantly lower than those before HDBR (P< 0.05). Neither control nor CM groups showed significant differences in the pulse rate, SpO2, pulmonary volume and pulmonary ventilation function over the HDBR observation time. Postural changes can lead to variation in lung volume and ventilation function, but a HDBR model induced no changes in pulmonary function and therefore should not be used to study AG CMs.

   Twenty Iraqi ducks hearts ( 10 male and 10 female ) have been  used for   demonstration  and illustration of heart's valves  and chambers  as well as  anatomical   and morphological site of view to explain what modifications had been take place for ducks heart  to perform  his normal life at the  circumstances  of  high  blood  pressure  and  pulse  rate. The heart  which has distinctly pointed  apex  was  built   in simple  manner located  in a transparent  taught  heart  pericardial  sac. It   was pyramidal in shape  externally  and  has a longitudinal  salcus  passing  to the  right  side, the  anterior of  the   heart  is  divided  into two  unequal  anterior  chamber  similar  to  those of mammalian  hear  .The heart valves are modified  in  order to  minimize  the  fraction  that occur as a result of  high  blood  pressure  and  pulse  rate  of  the  duck  heart , also  the  muscular  trabeculae   replace  the  chordate  tendineae  , which  were  present in the  mammalian    heart  in order to  minimize  the  fraction  resulting  from high  pulse  rate..

Effects Of Aging

An attempt was made to assess the effects of aging, regional differences, and draught load applied on draught potential of Umblachery cattle, an important draught breed of South India. Age had a highly significant effect (p less than 0.01) on all morphometric traits, stride length, and significant effect (p less than 0.05) on pulse rate after work. The middle age group (5.0 to 7.5 years) with more substantial stride length was identified as the critical productive age group for draught ability. Regional differences had a highly significant (p less than 0.01) influence on stride length, horsepower, and a significant effect (p less than 0.05) on pulse rate after work. The optimum draught load with which Umblachery breed could give uniform and maximum power output was found to be around 75 to 78 kg.
