We assessed the cardiorespiratory effects of laparoscopic procedures in 27 infants aged between 36 and 365 days. Infants were monitored and anaesthetised in a standardised manner. Heart rate, mean arterial pressure, end-tidal carbon dioxide and oxygen saturation were recorded, and blood gases were measured at 5 min after intubation, 15 and 30 min after carbon dioxide pneumoperitoneum, 5 min aft...

In neonatology, blood gas analysis is a useful tool in the evaluation of the health of newborns and plays a key role in early detection of critically ill subjects. Because blood gas analysis parameters have not previously been studied in any depth in donkey foals, this study was performed on 16 healthy Martina Franca donkey foals born after an uncomplicated delivery. Arterial and venous blood s...

Carbon dioxide is one of the major greenhouse gas (GHG) contributors. It is an obligation of the industry to reduce the amount of carbon dioxide emission to the acceptable limits. Tremendous research and studies are reported in the past and still the quest to find the suitable and economical solution of this problem needed to be explored in order to develop the most plausible absorber for carbo...

Copper trimesate (Cu-BTC) MOF has been pointed out as a promising adsorbent for separating carbon dioxide from methane. However, MOF’s need to be shaped prior to their use in packed bed adsorbers in order to reduce pressure drop; on the other hand, the production of mechanically resistant shaped bodies reduces their adsorption performance. In this work, Cu-BTC tablets provided by BASF are evalu...

The effect of CO2 pressure on commercial S.cerevisiae cells viability and on the rate of ethanol production in yeast, has been studied in batch cultures under 1,10 and 18 bar of CO2 pressures. The results show that the effect of CO2 pressure on ethanol productivity strongly depends on the temperature, glucose and starting biomass concentration and pressure itself. Under atmospheric CO2 pressure...

Carbon dioxide urethral pressure profiles were obtained in a group of continent and incontinent male patients. Cystometry, needle electromyography of the striated urinary sphincter, and cystourethroscopy were also performed in most patients. A characteristic reproducible urethral pressure profile can be obtained in the continent, obstructed, and incontinent groups. The results also showed that ...

The world-wide agreement to restrict the use of chlorofluorocarbons (CFCs) and hydrofluorocarbons has prompted recent research exploring the possibilities of replacement refrigerants, particularly those occurring naturally in the environment. One such natural refrigerant, carbon dioxide, has been shown for particular applications to have a COP which is competitive with current refrigerants. How...

Observations were made on the responses of the thoracic spiracles of Aedes aeypti and Aedes triseriatus to a constant carbon dioxide pressure in serial concentrations of oxygen in nitrogen and to the oxygen in nitrogen series alone. Lower than atmospheric pressures of oxygen caused an increase in the frequency and duration of spiracular opening. Higher than atmospheric pressures of oxygen had n...

BACKGROUND/AIM The Global initiative for chronic obstructive lung diseases (GOLD) reports a staging system for chronic obstructive pulmonary disease (COPD) based on airflow limitations at rest. Cardiopulmonary exercise testing (CPET) is used in surveys to determine the remaining working capacity concerning the degree of disability and the disability benefit payment after rehabilitation in patie...
