Pharmacokinetics of chlorofluorocarbon and hydrofluoroalkane metered-dose inhaler formulations of beclomethasone dipropionate. (1/62)

AIMS: To compare the pharmacokinetic profile of Beclazone (beclomethasone dipropionate) in its chlorofluorocarbon (CFC)-based and CFC-free formulations. METHODS: Ten healthy adults received a single 1,000 microg nominal dose (ex-valve) of beclomethasone dipropionate from a CFC inhaler (BEC-CFC) or from a CFC-free inhaler containing hydrofluoroalkane (HFA)-134a (BEC-HFA) in an open-label, randomized, two-way, crossover study. Blood samples were collected predose and over 12 h after inhalation. Comparisons were made of maximum plasma concentration of beclomethasone 17-monopropionate (17-BMP) (Cmax), and area under the plasma concentration vs time curve (AUC). RESULTS: The tmax was significantly (P<0.05) earlier with BEC-HFA and plasma levels were significantly higher following administration of BEC-HFA than BEC-CFC. Geometric mean values for AUC were 1.5 fold greater (90% CI 1.3-1.9) and for Cmax were 1.9 fold greater (90% CI 1.6-2.6) following BEC-HFA than BEC-CFC. CONCLUSIONS: Our data in healthy volunteers would not be consistent with the manufacturers' recommendation for a microgram equivalent (1:1) nominal dose switch between these HFA and CFC formulations. Further well designed trials are required in asthmatic patients to properly define their respective dose-response relationships for antiasthmatic and systemic adverse effects.  (+info)

Comparison of the safety of drug delivery via HFA- and CFC-metered dose inhalers in CAO. (2/62)

The objective of this study was to compare the long-term safety of a fixed combination of fenoterol hydrobromide (50 microg) and ipratropium bromide (20 microg) delivered using a metered dose inhaler (MDI) formulated with a non-chlorinated propellant, hydrofluoroalkanel34a (HFA-MDI), with delivery using the conventional chlorofluorocarbon propellant (CFC-MDI, Berodual/Bronchodual). The study was designed according to Safety Assessment of Marketed Medicines (SAMM) guidelines, to reflect as far as possible the use of MDls under normal prescribing conditions. Two thousand and twenty-seven patients with chronic airways obstruction (CAO) were enrolled from 99 centres in France, 95 centres in Germany and 24 centres in Italy. Following a 2-week run-in period, patients were randomized on a 2:1 basis (1,348 patients to HFA-MDI, 679 patients to CFC-MDI) to receive a flexible dose regimen of the combination (2 puffs, 2-4 times a day, as prescribed by the investigator) during a 12-week open label phase. The overall incidence of adverse events was comparable between both groups. In addition, the incidence of respiratory side effects was also similar, with CAO exacerbations or bronchitis the most frequently recorded events. The safety profile of the HFA formulation was comparable to those of the marketed CFC-MDIs used in Germany and France/Italy. No clinically significant differences were detected between HFA134a or CFC driven inhalers on the switch from CFC- to HFA-MDI (2 weeks before randomisation versus 2 weeks after randomization). There was a trend for taste complaints to be reported more frequently by patients in the HFA-MDI group (0.7% before randomization versus 3.4% after randomization). This, however, was an expected finding as the HFA134a formulation does have a different taste to the CFC formulation. No difference between formulations was observed in the incidences of coughing or paradoxical bronchospasm. The incidence of falls in FEV1 >15% within 15 min following inhalation at each of the clinic visits was 1.2% for both CFC- and HFA-MDIs. In conclusion, administration of a fenoterol/ipratropium bromide combination via hydrofluoroalkane-metered dose inhaler is as safe as delivery by the currently available chlorofluorocarbon-metered dose inhaler, in an extended population of patients with CAO under normal prescribing conditions.  (+info)

Fenoterol hydrobromide delivered via HFA-MDI or CFC-MDI in patients with asthma: a safety and efficacy comparison. (3/62)

The main objective of the study was to compare the long-term safety and tolerability of fenoterol hydrobromide delivered using a metered-dose inhaler formulated with the alternative propellant, hydrofluoroalkane 134a (HFA-MDI), with delivery using the currently available chlorofluorocarbon MDI (CFC-MDI; Berotec 100). A further objective was to compare the efficacy of fenoterol HFA-MDI with fenoterol CFC-MDI, using the pulmonary function parameters of forced expiratory volume in 1 sec (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF). Following a 2-week run-in phase, a 12-week, double-blind parallel group comparison was undertaken in 290 patients randomized on a 2:1 basis to two puffs of 100 microg fenoterol four times a day (HFA-MDI=197 patients; CFC-MDI=93 patients). A total of 236 patients in this multi-centre study completed the trial as planned. The overall incidence of adverse events (AEs) was similar in both groups (29.9% of HFA-MDI patients and 28% of CFC-MDI patients). Reports of respiratory disorder AEs were also comparable (21.8% HFA-MDI; 22.6% CFCMDI). End of study laboratory tests, ECG, pulse, blood pressure and physical examination showed no significant differences from pre-study baselines in either group and both treatments appeared to be well tolerated. Pre-dose FEV1 measurements taken at the three clinic visits were constant and increase in FEV1 at 5 and 30 min post-dose demonstrated equivalent efficacy for the two formulations. No difference between the two groups was observed in PEF or in the use of rescue medication. We conclude from these findings that the long-term safety and efficacy profile of fenoterol HFA-MDI is comparable to that of the fenoterol CFC-MDI.  (+info)

Delivery of fenoterol via Respimat, a novel 'soft mist' inhaler. a randomised, double-blind (within device), placebo-controlled, cross-over, dose-ranging study in asthmatic patients. (4/62)

BACKGROUND: The phase-out of chlorofluorocarbons (CFCs) for metered dose inhalers (MDIs) has prompted the development of alternative propellants and the design of propellant-free devices for inhalation therapy. OBJECTIVE: This study was carried out to determine the dose of fenoterol inhaled from Respimat (RMT), a new propellant-free soft mist inhaler, which is equivalent in terms of efficacy and safety to 1 puff of either 100 or 200 microg fenoterol inhaled from a conventional CFC-MDI (Berotec). METHODS: Sixty-two asthmatic patients (35 male, 27 female) with a mean baseline FEV(1) of 1.7 liters, corresponding to 55% of the predicted normal value, were randomized at two study centers to 4 of a total of 8 possible treatments: placebo; 12.5, 25, 50, 100, or 200 microg fenoterol via RMT, and 100 or 200 microg fenoterol delivered via the MDI. RESULTS: Fifty-nine patients completed the study as planned. Results of the therapeutic equivalence test for the primary endpoint, average FEV(1) (AUC(0-6))/6 and for the secondary endpoint, peak FEV(1), showed that the 12.5- and 25-microg fenoterol doses administered via RMT were equivalent to the 100 microg fenoterol dose from the MDI. The 50-, 100- and 200-microg fenoterol doses delivered by RMT did not meet the criterion for therapeutic equivalence with the 100-microg dose from the MDI, and if tested for a difference would have been significantly different in favor of RMT. All 5 RMT fenoterol doses were therapeutically equivalent to the MDI 200-microg fenoterol dose. Headache, reported by 4 patients on test days and 2 patients between test days in those randomized to RMT, was the most common adverse event, but the active treatments were generally well tolerated with no dose-dependent increases in incidence or severity of adverse events observed. CONCLUSIONS: The results from the study suggest that safe and efficacious bronchodilation can be obtained from single-dose fenoterol administered via RMT. Use of lower absolute doses to obtain a clinically significant improvement in pulmonary function may be possible because of the increased lung deposition achievable with the novel soft mist inhaler.  (+info)

Factors affecting the efficiency of aerosol therapy with pressurised metered-dose inhalers through plastic spacers. (5/62)

AIM: The main objective of this study was to compare the in vitro delivery of salbutamol from a chlorofluorocarbon(CFC)-propelled pressurised metered-dose inhaler (pMDI) versus a newly developed hydrofluoroalkane(HFA)-propelled pMDI through various spacers. In addition, we aimed to study the effect on bronchodilator response when using an optimal pMDI/spacer combination for aerosol delivery compared to a suboptimal combination. METHODS: Particle size distribution and output from salbutamol pMDIs containing either CFC propellants (Ventolin) or HFA propellants (Airomir) were measured using a multistage liquid impinger (MSLI) and compared to that through both detergent-coated (non-static) or untreated (static) large volume (Nebuhaler, Volumatic) and small volume (Aerochamber) plastic spacers. Flow-volume curves (FEV1) were obtained from twelve asthmatic children with known significant bronchodilator response (8 males), aged 13-17 years, randomly inhaling salbutamol from a CFC-pMDI through a static spacer (Nebuhaler) and from an HFA-pMDI through a non-static spacer (Nebuhaler). RESULTS: In vitro output of particles in the respirable range (< 6.8 microns) from HFA-pMDIs was significantly higher than that from CFC-pMDIs using various spacers. Removal of electrostatic charge increased output from CFC- and HFA-pMDIs through all spacers by 17-82%. The mean (SD) bronchodilator response after inhalation of salbutamol from a CFC-pMDI through a static spacer was 7.1% (6.3%) compared to 17.5% (7.9%) after inhalation from an HFA-pMDI through a non-static spacer (p = 0.002). CONCLUSIONS: Use of a newly developed HFA-propelled pMDI greatly improves drug delivery through spacers compared to a CFC-propelled pMDI. However, electrostatic charge in plastic spacers remains the key determinant limiting delivery of salbutamol from a pMDI through spacers, and can be reduced by soaking the spacer in a household detergent. Using an optimal pMDI/spacer combination leads to a significantly improved bronchodilator response.  (+info)

Bedside tracer gas technique accurately predicts outcome in aspiration of spontaneous pneumothorax. (6/62)

BACKGROUND: There is no technique in general use that reliably predicts the outcome of manual aspiration of spontaneous pneumothorax. We have hypothesised that the absence of a pleural leak at the time of aspiration will identify a group of patients in whom immediate discharge is unlikely to be complicated by early lung re-collapse and have tested this hypothesis by using a simple bedside tracer gas technique. METHODS: Eighty four episodes of primary spontaneous pneumothorax and 35 episodes of secondary spontaneous pneumothorax were studied prospectively. Patients breathed air containing a tracer (propellant gas from a pressurised metered dose inhaler) while the pneumothorax was aspirated percutaneously. Tracer gas in the aspirate was detected at the bedside using a portable flame ioniser and episodes were categorised as tracer gas positive (>1 part per million of tracer gas) or negative. The presence of tracer gas was taken to imply a persistent pleural leak. Failure of manual aspiration and the need for a further intervention was based on chest radiographic appearances showing either failure of the lung to re-expand or re-collapse following initial re-expansion. RESULTS: A negative tracer gas test alone implied that manual aspiration would be successful in the treatment of 93% of episodes of primary spontaneous pneumothorax (p<0.001) and in 86% of episodes of secondary spontaneous pneumothorax (p=0.01). A positive test implied that manual aspiration would either fail to re-expand the lung or that early re-collapse would occur despite initial re-expansion in 66% of episodes of primary spontaneous pneumothorax and 71% of episodes of secondary spontaneous pneumothorax. Lung re-inflation on the chest radiograph taken immediately after aspiration was a poor predictor of successful aspiration, with lung re-collapse occurring in 34% of episodes by the following day such that a further intervention was required. CONCLUSIONS: National guidelines currently recommend immediate discharge of patients with primary spontaneous pneumothorax based primarily on the outcome of the post-aspiration chest radiograph which we have shown to be a poor predictor of early lung re-collapse. Using a simple bedside test in combination with the post-aspiration chest radiograph, we can predict with high accuracy the success of aspiration in achieving sustained lung re-inflation, thereby identifying patients with primary spontaneous pneumothorax who can be safely and immediately discharged home and those who should be observed overnight because of a significant risk of re-collapse, with an estimated re-admission rate of 1%.  (+info)

Exposure to halogenated hydrocarbons in the indoor environment. (7/62)

The indoor environment has frequently been ignored as a significant source of exposure to air pollutants. To date there are a number of documented examples of levels of indoor air pollutants greatly exceeding those levels which commonly occur in the outdoor environment. Among these instances are airborne buildup of polynuclear aromatics and cadmium from cigarette smoke, lead from burning candles, and vinyl chloride from use of aerosols containing this substance as a propellant. These examples suggest that there may be additional sources of indoor air pollutants, particularly halogenated hydrocarbons from aerosol products, which have heretofore not been generally recognized as important. The present paper endeavors to review those instances where halogenated hydrocarbons in the indoor air environment may build up to concentrations of potential public health concern. These considerations may be especially relevant in future years as increasing efforts are being made to insulate buildings more efficiently as a means to conserve energy. The available data strongly suggest that halogenated hydrocarbons are an important class of air pollutants in the indoor environment and that their presence in the outdoor environment should also be carefully examined. In this regard, halogenated hydrocarbons in the outdoor environment may also contaminate indoor air spaces.  (+info)

Moving from CFC aerosol to HFA aerosol or dry powder inhalers: what do patients think? (8/62)

BACKGROUND/OBJECTIVES: Environmentally friendly hydrofluoroalkane (HFA) pressurised metered-dose inhalers are currently being marketed to replace chlorofluorocarbon (CFC)-driven devices. It is uncertain whether these new formulations with different properties are acceptable to patients. Similarly, switching a patient to a dry powder inhaler (DPI) carries the risk of non-acceptance. METHODS: One hundred patients with obstructive airway disease on regular CFC aerosol inhaler medication underwent a standardised, structured interview. During the interview patients were asked to use a new HFA aerosol inhaler and three DPIs in random order. Patients' notions were recorded. RESULTS: Most patients (96) agreed to change from their CFC to the HFA inhaler, of those, only 12 did so with some reservation. Properties (taste, user-friendliness, design) of the HFA inhaler were rated favourably. DPIs represented an acceptable alternative to aerosol inhalers. In fact, 57 patients preferred a DPI over the HFA inhaler. Not all powder devices were equally acceptable. Replacing the CFC inhaler with patients' preferred alternative devices resulted in a more than 3-fold increase in costs. CONCLUSION: Concerns about the acceptability of reformulated CFC-free aerosol inhalers are ill founded. However, if given the choice, many patients prefer a DPI over the HFA inhaler. The transition offers an opportunity to review patients' current treatment and the proficiency of their inhaling technique. Moving to CFC-free inhalers will have revenue implications.  (+info)

A rapid burning propellant charge for applications including igniters, launch eject motors, and gas generators for automobile air bags. The propellant charge comprises a reticulated substrate having a quantity of interconnected ligaments and a coating of solid propellant material on the ligaments. In order to provide a large amount of surface area for a fast burn time, interstices are between coated ligaments to define propellant surface area for combustion. In applications where minimum smoke is desired, the reticulated substrate is preferably composed of carbon, graphite, or a non-combustible material, and the solid propellant material is preferably a minimum smoke type.
The ballistic properties of RDX-based propellants are highly dependent on the particle size of RDX used. The effect of RDX particle size on the burning rate and pressure exponent of the gun propellant was studied. Propellant formulation containing RDX to extent of 60 per cent in the composition was processed with varying particle size of RDX. Finished propellants in heptatubular and cord geometry were evaluated for ballistic aspects by closed vessel firing in a 700 cc vessel at a loading density of 0.18 g/cc. The data obtained clearly indicate that increase in particle size of RDX increases the burning rate as well as the pressure exponent ...

Nitroglycerin (NG) and nitrocellulose (NC) are constituents of double-base propellants used notably for firing antitank ammunitions. Nitroglycerin was detected in soil and water samples from the unsaturated zone (pore water) at an active antitank firing position, where the presence of high nitrate (NO 3 -) concentrations suggests that natural attenuation of NG is occurring. However, concentrations alone cannot assess if NG is the source of NO3 -, nor can they determine which degradation processes are involved. To address this issue, isotopic ratios (δ15N, δ18O) were measured for NO 3 - produced from NG and NC through various controlled degradation processes and compared with ratios measured in field pore water samples. Results indicate that propellant combustion and degradation mediated by soil organic carbon produced the observed NO3 - in pore water at this site. Moreover, isotopic results are presented for NO 3 - produced through photolysis of propellant constituents, which could be a ...

The Simple Depot mission was proposed by NASA in 2011 as a potential first PTSD mission, with launch no earlier than 2015, on an Atlas V 551. Simple Depot would utilize the used (nearly-emptied) Centaur upper stage LH2 tank for long-term storage of LO2 while LH2 will be stored in the Simple Depot LH2 module, which is launched with only ambient-temperature gaseous Helium in it. The SD LH2 tank was to be 3 metres (9.8 ft) diameter and 16 metres (52 ft) long, 110 cubic metres (3,900 cu ft) in volume, and store 5 mT of LH2. At a useful mixture ratio (MR) of 6:1 this quantity of LH2 can be paired with 25.7 mT of LO2, allowing for 0.7 mT of LH2 to be used for vapor cooling, for a total useful propellant mass of 30 mT. ... the described depot will have a boil-off rate of approaching 0.1 percent per day, consisting entirely of hydrogen.[36] In September 2010, ULA released a Depot-Based Space Transportation Architecture concept to propose propellant depots that could be used as way-stations for ...

The amount of propellant is normally measured either in units of mass or weight. If mass is used, specific impulse is an impulse per unit mass, which dimensional analysis shows to have units of speed, and so specific impulses are often measured in meters per second and are often termed effective exhaust velocity. However, if propellant weight is used, an impulse divided by a force (weight) turns out to be a unit of time, and so specific impulses are measured in seconds. These two formulations are both widely used and differ from each other by a factor of g0, the dimensioned constant of gravitational acceleration at the surface of the Earth.. Note that the rate of change of momentum of a rocket (including its propellant) per unit time is equal to the thrust.. The higher the specific impulse, the less propellant is needed to produce a given thrust during a given time. In this regard a propellant is more efficient the greater its specific impulse.

Only recently I became aware that paper conservators were using a similar disposable propellant canister for spray applications of deacidifying reagents on works of art. Procedural questions had also been raised about the cause of yellowing which accompanied some, but not all, methods of application of the same reagent. It quickly became clear that these canisters also possessed oil in the propellant reservoir. While the oil did not seem to have caused the observed yellowing in this particular case, conservators should consider that staining may be caused by the unknown contents of such propellant systems. Such problems are easily identified. A canister of the propellant should be completely discharged, without anything attached to the aspirator, ...
The 8 inch prevalves were normally open, pneumatically actuated, electrically controlled, butterfly-gate type valves. Supported propellant flow rates were 386 pounds of LOX per second at 132 psi; and 78 pounds of LH2 at 132 psi. A built-in four-way pneumatic control solenoid permitted 750 +/- 50 psig helium pressure to actuate the butterfly-gate (response time was 1000 milliseconds). Should a loss of pneumatic or electrical power occur, the prevalves were designed to be spring actuated to return to the open position. During ground operations, the Pre-Valve was opened to permit propellant fueling and in conjunction with the recirculation subsystem, allow the propellant to cycle through the feed lines and valves servicing the J2 engines, maintaining uniform cryogenic density and temperature, and precluding the formation of gas in propellant plumbing. Following propellant tank loading and all the way up to the point of S-IC (Saturn V first stage) separation, the Pre-Valves were commanded to remain ...
In metered-dose inhalers aerosol is generated with the aid of propellants like chlorofluorocarbons (CFC) or hydrofluoralkanes (HFA). They have a high dose consistency and average particle size as well as fine particle fraction are independent of the inspiratory air flow.. Mainly drugs in metered-dose inhalers are suspended within the propellant. They need to be shaken before use and generate particles with an average size of 3-5 µm. Substances insolution do not require shaking and are released from the inhaler with considerably smaller average size of about 1 µm thus being more easily deposited in the distal lung areas.. In most metered-dose inhalers aerosol inhalation has to be coordinated with dose actuation. Several studies have demonstrated that up to 70% of patients fail to complete the correct inhalation manoeuvre. This problem is overcome by breath-actuation or inhalation aids like spacers and holding chambers, which contrawise are more bulky to carry.. ...

Hairspray came into vogue after World War II when the cosmetics industry adopted the use of aerosol spray technology developed by the Department of Agriculture for use with insect sprays during the war. This transfer of technology to the business of beauty helped make womens hair styles such as the beehive and the bouffant possible. Although the use of hairspray has declined with the popularity of more natural hairstyles, hairspray is commonly used by men and women today. Todays typical hairspray contains polymers (chain-like molecules) in a solvent and sometimes a propellant. After spraying, the solvent evaporates and leaves behind a stiff layer of the polymers on the hair to help keep it in place. The propellant is usually a liquefied gas under pressure that forces the hairspray out of an aerosol can and produces a mist. Sometimes the propellant is also the solvent. Due to health and environmental concerns, the US Food and Drug Administration (FDA) banned certain propellants (e.g., ...
Work involved during the preflight preparation of spacecraft involves the handling of materials that are very toxic to humans. These toxins attack the respiratory and skin systems and, therefore, impose the requirement for full suit enclosures. The weight, structure, and operating parameters of such a suit can be expected to have a significant effect upon the metabolic and thermal responses of the user, especially in high workload situations and ambient temperature extremes.. This paper describes the testing of the operational version of the Propellant Handlers Ensemble (PHE). In particular, parameters affecting the physiology of the user were measured during a work-rest regimen performed in three temperature environments: −7, 23, and 43°C (20, 74, and 110°F). Six subjects performed tests in these environments in two versions of the PHE, the autonomous backpack version and the hoseline supplied configuration. Measurements included heart rate, four skin temperatures, rectal temperature, ...

Reservoir volume in a drug delivery device is sensed by providing a capacitor, the capacitance of which varies with bellows position or, alternatively, with the amount of propellant liquid absorbed in a dielectric material. In one embodiment, a capacitance is provided between a surface of the bellows, which acts as a first capacitor plate, and a conductive surface disposed proximate the bellows, which acts as a second capacitor plate. As the bellows moves from its extended full position to its collapsed empty position, the area of overlap, and therefore the capacitance between the first and second plates varies from a maximum value to a minimum value. In another embodiment, a variable capacitor is provided with an absorbent material. The absorbent material absorbs the liquid phase of the propellant in the pump housing and acts as a dielectric between two stationary conductive plates provided in the housing. The amount of liquid propellant absorbed in the absorbent material varies with the reservoir
In current liquid rocket engines, in both monopropellant or bipropellant configurations, the feeding system provides the propellants at a pressure that allows them to be injected into the thrust chamber by means of turbo pumps or pressurized systems such as direct gas pressurization, flexible bags within tanks or piston pressurization1,2.Even if the engine can be operated in pulse mode, the feed system is currently designed in order to guarantee the nominal steady state operation and, consequently, the nominal feed pressure should be higher than the expected one inside the combustion chamber due to pressure losses inside pipelines, valves and injectors. Except for the propellant itself, most of the weight of the propulsive system consists in the pressurizing system3.PulCheR (Pulsed Chemical Rocket with Green High Performance Propellants) 4,5 is a R&D project funded by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement n°313271.

TY - CONF. T1 - In-situ measurements of alumina particle size and optical constants in composite solid propellant flames. AU - Brewster, Quinn. AU - Parry, David L.. PY - 1987/1/1. Y1 - 1987/1/1. N2 - The complex refractive index (n-ik) at 0.6328ym and the effective optical diameter of alumina particles in ammonium perchlorate (AP) composite solid propellant flames were measured in-situ using an inverse light scattering technique. Measured bidirectional reflectance and transmittance values were used to obtain n values, between 1.3 and 1.8 and k values between 0.04 and 0.6. The effective alumina diameter was determined (by the absence or existence of solutions to the Inverse scattering problem) to be between 0.26 and 0.30 um. Forward scattering dominated back scattering to such an extent that even a linear anisotropic scattering model would be inaccurate in describing the radiative transport. The alumina single scattering albedo was found to be in the range 0.5 to 0.7.. AB - The complex ...

The most popular form of Aerosol can works by storing some fluid under very high pressure, which then propels some other fluid out of the can when an opening is introduced. More specifically, the propellant is some fluid that boils at well below room temperature and the other fluid (product), like hairspray, insect repellant, or paint, boils at much higher temperatures than room temperature. Usually, the product is put in the can first. Next, the can is sealed and then the propellant is pumped in at high pressure so its forced to stay in liquid form. The spring loaded valve is at the top, with a long stem attached that goes to the bottom. When the valve is open, the high pressure propellant above the product liquid is able to expand and form a gas layer, which then pushes down on the product and some of the remaining propellant still in liquid form. This results in the liquids being squirted out. The nozzle is also constructed such that it will atomize the liquid as it is sprayed out, making ...

Ultimately, this is because of the enormous amount of energy stored in the propellants required to make a rocket fly. Ground support personnel need to exercise great care even when dealing with safe propellants, such as the classic combination of kerosene and liquid oxygen. On the other end of the spectrum you have chemicals that are so unstable and toxic that they cant be handled without special training and equipment.. One of the most dangerous chemicals ever used in rocket propulsion is hydrazine; and yet from the Second World War to the present day, its been considered something of an occupational hazard of spaceflight. While American launch vehicles largely moved away from using it as a primary propellant, hydrazine is still commonly used for smaller thrusters on spacecraft.. When SpaceXs Crew Dragon exploded in April during ground tests, the release of approximately one and a half tons of hydrazine and nitrogen tetroxide propellants required an environmental cleanup at the ...
Find the blue Begin button to the right to start. Text of petition: The FDA, in compliance with the Montreal Protocol, has banned the use of life-saving CFC propellant albuterol asthma rescue inhalers in order to help restore the ozone layer, even though it has been widely acknowledged that these CFC inhaler emissions are too trivial to harm the ozone layer: Leslie Hendeles, University of Florida Professor of Pharmacy and Pediatrics, has noted that CFC inhalers release negligible amounts of the propellant and DO NOT POSE A THREAT TO OZONE DEPLETION. (LINK 1) The amount of CFCs in inhalers is minute, so BANNING THEM WONT MAKE ANY IMPROVEMENT (in the ozone layer). says Sallie Baliunas, an astrophysicist at Harvard University and the George Marshall Institute (LINK 2) CFC rescue inhalers have proven their safety, effectiveness, and reliability to tens of millions of asthma, COPD, cystic fibrosis, lung cancer, and other pulmonary patients for almost thirty years. Therefore, before the FDA could ...
Inhalation aids used with pMDIs can be divided into holding chambers with a larger volume and spacers which are not as bulky. Both kinds of inhalation aids facilitate the coordinationbetween actuation and inhalation essential for the correct use of a pMDI. Additionally inhalation aids reduce oropharyngeal deposition frequently observed, when aerosol is released directly with high pressure from metered-dose inhalers.. In contrast to spacers holding chambers feature an inspiratory valve which inhibits the direct emission of aerosol from and exhalation into the hollow space. Due to intermediate storage of aerosol in the inhalation aid propellant evaporates resulting in the generation of smaller particles. Thereby bioavailability of the aerosol and intrabronchial deposition of particles is increased.. However filling a holding chamber with more than a single puff from the inhaler or delay of inspiration reduces the amount of breathable particles. Using a spacer still requires some coordination ...

Care guide for How to Use A Metered-Dose Inhaler and a Spacer. Includes: possible causes, signs and symptoms, standard treatment options and means of care and support.
I have been using the new inhalers for the past year. The quality of my life and the degree of activity Im able to enjoy has been much reduced. I used to be able to run for two miles! Now I can barely jog half a block.. Its the same medication, albuterol, but its driven out by a different propellant. Just doesnt go as deeply into the lungs. VERY frustrating.. The only alternative is to get a nebulizer machine and some liquid albuterol and saline solution. This is what your doctor would do for you if you came into his office with a bronchospasm. The trouble is, of course, that you cant take the nebulizer with you if youre going on a hike or a camping trip, and its awkward to drag around even if youre just going to the office. But when push comes to shove, it does work. No propellants, just drug + saline + air.. And take your inhaled steroids so you dont need much in the way of bronchodilators.. ...
Everybody raves about coconut oil for cooking but for some reason Ive never been that fussed about it. Maybe its because I dont like coconut flavours but Ive never wanted to try it (even though they say its healthier for you). Well, for one olive oil spray is a much cheaper alternative to coconut oil. I dont want to be spending a fortune but I still want my hair to feel healthy and my skin to feel soft and of course my food to taste delicious! With olive oil you get much better quality but at a cheaper price so its a win win situation in my opinion. Jay and I are obsessed with using the olive oil sprays, our favourite is the garlic infused one as its got such a mild but rich taste. Its such a brilliant alternative to using fry light which we used to use religiously. Olive Oil spray is 100% natural and has NO added water, alcohol, aerosol propellant, emulsifiers or antioxidants in it whereas other oil sprays have these ingredients - making it ultimately a healthier choice. We like to use ...

This mixture of gases is then passed over a bed of a zeolite in its acid form, HZSM-5, heated to ca 650 K, to produce the mixture of hydrocarbons (with 5-10 carbon atoms) for use as petrol.. DME can be used in a different way. Although it is a gas at ambient temperatures, it can be readily liquefied under pressure and is considered to be an attractive alternative fuel to diesel oil. The vehicles need a compression ignition engine with a fuel system specifically developed to operate on DME. There have been a number of DME vehicle demonstrations in Europe and in the US, including one in which a customer operated 10 vehicles for 750,000 miles. Emission standards for particulates can be met without the use of filters. As with conventional diesel vehicles, oxides of nitrogen (NOx) emissions can be reduced in the usual way with a solution of urea.. DME is also mixed with liquid petroleum gas (LPG) as a fuel for use in homes. Its main use at present, though, is as an aerosol propellant.. The first MTG ...

Oxidation of aqueous sodium phenylmethane-nitronate with ammonium persulfate yields d,1-(major product) and meso-1,2-dinitro-1,2-diphenylethanes along with cis-alpha-nitrostilbene, alpha, beta, gamma-triphenyl-alpha-nitropropene, 3,4,5-triphenylisoxazoline oxide, 3,4,5-triphenylisoxazole, benzaldehyde, and benzoic acid. The complex condensation products are derived by the actions of bases on the 1,2-dinitro-1,2-diphenylethanes or from benzaldehyde and phenylnitromethane. The actions of persulfate on nitronates are greatly accelerated by trace quantities of silver ion. Salts of 1-nitropropane and 2-methyl-1-nitropropane respectively were oxidized with persulfates in the presence or absence of silver ion to give oxidative-dimers. Reaction of potassium 1-nitropentane-1-nitronate with ammonium persulfate yielded valeric acid and valeramide. The sodium salt of phenyldinitromethane is not oxidized by aqueous persulfate. Possible mechanisms for formation of the products of the various oxidation reactions are
Nitrocellulose is complex stuff. It is generally considered to be the fully nitrated version of cellulose, in which every available alcohol functional group is converted to a nitrate:. $$\ce{[C6H10O5]n +3HNO3 -, (C6H7O2(ONO2)3]n +3H2O}$$. In principal it probably contains some small amount of partially and/or non-nitrated units.. If we consider nitrocellulose to be fully nitrated, then the combustion reaction is:. $$\ce{ 2C6H7N3O11 + 9/2O2 -, 12CO2 + 3N2 + 7H2O}$$. For nitroglycerin $(\ce{C3H5N3O9})$:. $$\ce{2C3H5N3O9 -, 6CO2 + 3N2 + 5H2O + 1/2O2}$$. It will depend on the ratio of nitrocellulose to nitroglycerin what the overall $\ce{CO2}: \ce{N2}:\ce{H2O}$ mole ratio is. Ill leave you to figure out the mass ratios using the molecular masses of the products.. ...
I see in the volatiles article that hydrogen is the most bundant volatile on the Moon. Is this in regoltih alone or mostly in ice at the poles? If so, is it available in the regolith to be viable for use as rocket fuel? T.Neo 13:04, 1 August 2008 (UTC) Just the regolith alone. Harvesting regolithic hydrogen for use as rocket fuel is likely to be much less economical than using it to compensate for the small but gradual leakage of atmosphere during oxygen production as well as that from pressurized habitats. The ice at the poles is another question entirely. There is disagreement as to how that hydrogen should be utilized. Personally, I would prefer to keep it on the moon while shipping oxygen back to LEO for a propellant depot. Probably cheaper to ship hydrogen to LEO than to ship it to the moon to make up for a future shortage. - Jarogers2001 19:30, 1 August 2008 (UTC) So if you ship O2 to LEO to use as propellant, where does the fuel come from?
