having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Graphene has been attracting great interest because of its distinctive band structure and physical properties. Today, graphene is limited to small sizes because it is produced mostly by exfoliating graphite. We grew large-area graphene films of the order of centimeters on copper substrates by chemical vapor deposition using methane. The films are predominantly single-layer graphene, with a smal...
The determination of the percentage of CO(2) in the alveolar air, by the method of Haldane and Priestley, is sufficiently accurate for clinical purposes when the individual is at rest. It is evident, however, that an error may arise in the determination of the percentage of CO(2) in the alveolar air, due to the time during the forced expiration, short of the extreme limit, at which the sample m...
Background We aimed to identify the hierarchy of rates of decline in 16 physical functioning measures in U.S. and English samples, using a systematic and integrative coordinated data analysis approach. Methods The U.S. sample consisted of 13,612 Health and Retirement Study participants, and the English sample consisted of 5,301 English Longitudinal Study of Ageing participants. Functional los...
ancylostoma tubaeforme was originally described as a separate species parasitizing the cat. the adults of a. tubaeforme are 7 to 12 mm long. a. tubaeforme can be differentiated from the adults of a. braziliense and a. ceylanicum by the presence of three teeth. here we describe the first report of a. tubaeforme in a persian young female leopard, 2-3 years old, with head and trunk length 120 cen...
