the current study investigated the effect of short-term selection for four week body weight (bw) on performance of divergent lines of japanese quail and their crosses. the mean of bw at hatching time, one, two, three and four week oldand bw at sexual maturity time, age at sexual maturity, number of eggs (from 50 to 100 days old), mean of egg weight, percentage of fertility and hatchability in e...

1. Recordings were made of the pattern of breathing during and after smoking a cigarette in 14 smokers and nine non-smokers. 2. The most consistent effect was an increase in tidal volume during smoking which reverted to baseline over 1-2 min. Changes in breath times were smaller and less consistent. Similar effects were observed with intermittent inhalations of charcoal. 3 In four subjects the ...

Understanding nodal tidal characteristics is essential for accurate long-term prediction. Observational evolution of tides mainly based on tide gauge records in coastal areas which are limited time and space, thus impeding coherent determinations basin-wide patterns variability. In this paper, we indicate the potential satellite altimeter data to investigate 18.61-year modulations main constitu...

Since the 1950s, numerous publications of analytical studies of tidal wave propagations in coastal aquifers have been appeared. This paper reviews the following aspects: importance of tidal effects in studies of coastal areas, analytical studies of tide-induced groundwater flow and related case studies. Finally several important open problems in analytical studies of tide-induced groundwater fl...

We evaluated the effects of the rate and volume of tidal ventilation on airway resistance (Raw) during intravenous methacholine (MCh) challenge in mechanically ventilated rabbits. Five rabbits were challenged at tidal volumes of 5, 10, and 20 ml/kg at a frequency of 15 breaths/min and also under static conditions (0 ml/kg tidal volume). Four rabbits were subjected to MCh challenge at frequencie...

HRDI (High Resolution Doppler InterferometerUARS) winds data have been analyzed in 4-latitude by 10-longitude cells at 96 km to obtain the global distribution of the solar-tidal amplitudes and phases. The solstices June–July (1993), December–January (1993–1994), and one equinox (September–October, 1994) are analyzed. In an earlier paper (Manson et al., 2002b) the emphasis was solely upon the lo...

abstract: the new neonatal ventilation methods have been developed along with utilization of new technological tools.this device is synchronized with the patient’s respiratory efforts. the ideal synchronized breath needs to be synchronous with initiation, size, and termination of the breath without delay in detecting of initial resiratory effort by device .the synchrony of respiration contribut...

background: patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. monitoring of end-tidal carbon dioxide (etco2) as a surrogate, noninvasive measurement of arterial carbon dioxide (paco2) is one of the methods used for this purpose in intubated patients. objectives: the aim of the present trial was to study the relationship between end-tidal c...
