Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.

A community outbreak of Legionnaires' disease linked to hospital cooling towers: an epidemiological method to calculate dose of exposure. (1/184)

BACKGROUND: From July to September 1994, 29 cases of community-acquired Legionnaires' disease (LD) were reported in Delaware. The authors conducted an investigation to a) identify the source of the outbreak and risk factors for developing Legionella pneumophila serogroup 1 (Lp-1) pneumonia and b) evaluate the risk associated with the components of cumulative exposure to the source (i.e. distance from the source, frequency of exposure, and duration of exposure). METHODS: A case-control study matched 21 patients to three controls per case by known risk factors for acquiring LD. Controls were selected from patients who attended the same clinic as the respective case-patients. Water samples taken at the hospital, from eight nearby cooling towers, and from four of the patient's homes were cultured for Legionella. Isolates were subtyped using monoclonal antibody (Mab) analysis and arbitrarily primed polymerase chain reaction (AP-PCR). RESULTS: Eleven (52%) of 21 case-patients worked at or visited the hospital compared with 17 (27%) of 63 controls (OR 5.0, 95% CI : 1.1-29). For those who lived, worked, or visited within 4 square miles of the hospital, the risk of illness decreased by 20% for each 0.10 mile from the hospital; it increased by 80% for each visit to the hospital; and it increased by 8% for each hour spent within 0.125 miles of the hospital. Lp-1 was isolated from three patients and both hospital cooling towers. Based on laboratory results no other samples contained Lp-1. The clinical and main-tower isolates all demonstrated Mab pattern 1,2,5,6. AP-PCR matched the main-tower samples with those from two case-patients. CONCLUSION: The results of our investigation suggested that the hospital cooling towers were the source of a community outbreak of LD. Increasing proximity to and frequency of exposure to the towers increased the risk of LD. New guidelines for cooling tower maintenance are needed. Knowing the location of cooling towers could facilitate maintenance inspections and outbreak investigations.  (+info)

Buildings operations and ETS exposure. (2/184)

Mechanical systems are used in buildings to provide conditioned air, dissipate thermal loads, dilute contaminants, and maintain pressure differences. The characteristics of these systems and their operations h implications for the exposures of workers to environmental tobacco smoke (ETS) and for the control of these exposures. This review describes the general features of building ventilation systems and the efficacy of ventilation for controlling contaminant concentrations. Ventilation can reduce the concentration of ETS through dilution, but central heating, ventilating, and air conditioning (HVAC) can also move air throughout a building that has been contaminated by ETS. An understanding of HVAC systems is needed to develop models for exposures of workers to ETS.  (+info)

Germicidal ultraviolet irradiation in air conditioning systems: effect on office worker health and wellbeing: a pilot study. (3/184)

OBJECTIVES: The indoor environment of modern office buildings represents a new ecosystem that has been created totally by humans. Bacteria and fungi may contaminate this indoor environment, including the ventilation systems themselves, which in turn may result in adverse health effects. The objectives of this study were to test whether installation and operation of germicidal ultraviolet (GUV) lights in central ventilation systems would be feasible, without adverse effects, undetected by building occupants, and effective in eliminating microbial contamination. METHODS: GUV lights were installed in the ventilation systems serving three floors of an office building, and were turned on and off during a total of four alternating 3 week blocks. Workers reported their environmental satisfaction, symptoms, as well as sickness absence, without knowledge of whether GUV lights were on or off. The indoor environment was measured in detail including airborne and surface bacteria and fungi. RESULTS: Airborne bacteria and fungi were not significantly different whether GUV lights were on or off, but were virtually eliminated from the surfaces of the ventilation system after 3 weeks of operation of GUV light. Of the other environmental variables measured, only total airborne particulates were significantly different under the two experimental conditions--higher with GUV lights on than off. Of 113 eligible workers, 104 (87%) participated; their environmental satisfaction ratings were not different whether GUV lights were on or off. Headache, difficulty concentrating, and eye irritation occurred less often with GUV lights on whereas skin rash or irritation was more common. Overall, the average number of work related symptoms reported was 1.1 with GUV lights off compared with 0.9 with GUV lights on. CONCLUSION: Installation and operation of GUV lights in central heating, ventilation and air conditioning systems of office buildings is feasible, cannot be detected by workers, and does not seem to result in any adverse effects.  (+info)

Follow up investigation of workers in synthetic fibre plants with humidifier disease and work related asthma. (4/184)

OBJECTIVE: To investigate the clinical and sociomedical outcome in patients with various clinical manifestations of humidifier disease and work related asthma after removal from further exposure. METHODS: Follow up investigation (range 1-13 years) of respiratory symptoms, spirometry, airway responsiveness, sickness absence, and working situation in patients with (I) humidifier fever (n = 12), (II) obstructive type of humidifier lung (n = 8), (III) restrictive type of humidifier lung (n = 4), and (IV) work related asthma (n = 22). All patients were working at departments in synthetic fibre plants with microbiological exposure from contaminated humidification systems or exposure to small particles (< 1 micron) of oil mist. RESULTS: At follow up patients with work related asthma were less often symptom free (37%, 7/19) than patients with humidifier disease (I, II, III) (67%, 16/24). Mean forced expiratory volume in one second (FEV1) of patients with obstructive impairment had been increased significantly at follow up but still remained below the predicted value. Mean forced vital capacity (FVC) of patients with initially restrictive impairment had returned to normal values at follow up. Airway hyperresponsiveness at diagnosis persisted in patients with obstructive impairment (II + IV 14/17, but disappeared in patients with humidifier fever (3/3) and restrictive type of humidifier lung (2/2). In patients with obstructive impairment (II + IV), FVC and FEV1 at diagnosis were negatively associated with the duration between onset of symptoms and diagnosis and the number of years of exposure. Those with positive pre-employment history of respiratory disease had a lower FEV1 at diagnosis. Sickness absence due to respiratory symptoms decreased in all groups of patients after removal from further exposure, but this was most impressive in patients with the humidifier lung (II, III) and patients with work related asthma (IV). At follow up 83% of the patients were still at work at the same production site, whereas 11% received a disability pension because of respiratory disease. CONCLUSION: In patients with work related respiratory disease caused by exposure from contaminated humidification systems or oil mist, removal from further exposure resulted in clinical improvement, although, especially in those with obstructive impairment, signs persisted. Because of the possibility of transferring patients to exposure-free departments most patients could be kept at work.  (+info)

Airborne infection in a fully air-conditioned hospital. I. Air transfer between rooms. (5/184)

Measurements have been made of the extent of air exchange between patient rooms in a fully air-conditioned hospital using a tracer-gas method. When the rooms were ventilated at about six air changes per hour, had an excess airflow through the doorway of about 0.1 m.3/sec. and the temperature difference between rooms and corridor was less than 0.5 degrees C., concentrations of the tracer in rooms close to that in which it was being liberated were 1000-fold less than that in the source room. This ratio fell to about 200-fold in the absence of any excess airflow through the doorways. Considerable dilution took place along the corridors so that the concentration fell by around 10-fold for every 10 m. of corridor.  (+info)

Airborne infection in a fully air-conditioned hospital. II. Transfer of airborne particles between rooms resulting from the movement of air from one room to another. (6/184)

Experiments were conducted simultaneously with gas and particle tracers to determine the relative loss of particles between source and recipient sites in the hospital ward units. The magnitude of this loss could be accounted for by the assumption of sedimentation from well-mixed air masses during the time required for movement between source and recipients sites. As a consequence of this loss the degree of isolation between patient rooms for airborne particles was between 4 and 25 times greater than that for gaseous contamination, which reflects the actual transport of air between the rooms. The design and construction of portable spinning-disk particle generators suitable for field studies is discussed.  (+info)

Airborne infection in a fully air-conditioned hospital. II. Transport of gaseous and airborne particulate material along ventilated passageways. (7/184)

A mathematical model is described for the transport of gaseous or airborne particulate material between rooms along ventilated passageways. Experimental observations in three hospitals lead to a value of about 0.06 m.2/sec. for the effective diffusion constant in air without any systematic directional flow. The 'constant' appears to increase if there is any directional flow along the passage, reaching about 0.12 m. 2/sec. at a flow velocity of 0.04 m./sec. Together with previously published methods the present formulae make it possible to calculate the expected average amounts of gaseous or particulate material that will be transported from room to room in ventilated buildings in which the ventilation and exchange airflows can be calculated. The actual amounts transported in occupied buildings, however, vary greatly from time to time.  (+info)

Airborne infection in a fully air-conditioned hospital. IV. Airborne dispersal of Staphylococcus aureus and its nasal acquisition by patients. (8/184)

Studies in a newly built hospital furnished with complete air conditioning where most of the patients are nursed in 6-bed rooms showed that the transfer of air from one patient room to another was very small, especially when there was substantial flow of air in a consistent direction between the patient rooms and the corridor, and that the direct transfer of airborne particles was even less. There was, however, no evidence of any reduction in the rates of nasal acquisition of Staphylococcus aureus compared with those to be found in naturally ventilated hospitals. The numbers of Staph. aureus found in the air of a given room that appeared to have originated from patient carriers in other rooms were many times greater than could be accounted for by direct airborne transfer. Although there was evidence that many carriers were not detected, detailed study showed that this excess transfer to the air of other rooms was genuine. It seems probable on the basis of investigations in this hospital and elsewhere that this excess transfer occurs indirectly, through dispersal from the clothing of the nursing and medical staff into the air of another room of strains with which their outer clothes have become contaminated while dealing with patients. Reduction in direct airborne transfer of micro-organisms from one room to another, whether by ventilation or other means, can only be of clinical advantage if transfer by other routes is, or can be made, less than that by the direct airborne route.  (+info)

The present invention describes a method and apparatus for conditioning air utilizing a desiccant based air conditioning system requiring substantially less regeneration energy than typical systems. This regeneration energy reduction is accomplished through the use of two separate desiccant devices and an indirect evaporative cooler having both a wet and dry side for air flow-through. The first desiccant device regeneration air is first passed through the wet side of the indirect evaporative cooler wherein it is humidified and heated. This air is then dehumidified by passing through the second desiccant device which operated at a high moisture content. This results in a substantial amount of moisture being adsorbed from the first regeneration air stream causing a substantial air temperature increase and thereby, reducing the auxiliary heat required. The second desiccant device may be regenerated with ambient air.

Air conditioners work by circulating warm air around the house. When this warm air enters a room, it warms the walls and floors, thereby cooling the air inside the room. The process of air conditioners is simple, because they are able to do so simply by using heat from the air to turn air into cold air. The process can be complicated when one adds a fan or furnace into the equation, but these appliances help circulate air throughout the house more efficiently, resulting in higher indoor temperatures.. In order to use the heating and air conditioning systems effectively, it is important to get proper ventilation. When the proper ventilation is not present, it creates many health problems. High levels of humidity in a home are a leading cause of respiratory problems, including asthma. This is because it increases the amount of mucus that collects in the respiratory system and creates a humid environment where bacteria can thrive. When a person has chronic sinusitis, for example, he or she may have ...
HVAC (stands for Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/or air conditioning system. Usually a sensing device is used to compare the actual state (e.g., temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g., start the blower). |br|More complex HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units. The building owner can monitor the system and respond to alarms generated by the system from local or remote locations. [HVAC control system.

Are you one of the many drivers who neglects to change their cars air filter on a regular basis? With the purchase of a new car, your sales person will normally include a maintenance schedule of things to have completed such as oil changes, tire rotations, battery checks and other standard items while your car is under warranty.. Amid respiratory concerns about outdoor air pollution, a vehicles air filter functions similarly to your lungs. A clogged air filter comes from gradual buildup of dirt and debris. It is recommended that you change your air filter every 12,000 to 15,000 miles. If you live in a rural area where you frequently travel down dirt or sandy roads, you will more than likely have to change your cars air filter more regularly. The car air filter for your engine is called an internal combustion filter. This is different from the cabin air filters that is used in your cars air conditioning system.. There are 3 types of internal combustion filters:. ...
A relatively new feature on the automotive scene, the cabin air filter is often overlooked in regular vehicle maintenance. Thats unfortunate, because the cabin air filter is just as important to the passengers as the engine air filter is to the vehicle. A cabin filter processes the air that enters the passenger compartment via the vehicles heating and air conditioning system, increasing passenger comfort by trapping particulates, pollen, and other irritants. For people with allergies and other sensitivities to airborne agents, the cabin filter represents a significant advance. Replacing the cabin air filter at the recommended interval, or sooner in areas where soot or pollen are prevalent, allows the passengers to breathe cleaner, fresher air - which makes any journey more enjoyable.. DENSO First Time Fit® replacement cabin filters are engineered for optimal airflow and filtration, meeting all OE requirements to the letter. Up to five layers of filter media are used to trap impurities down to ...
Air Filters for BMW Car Cabin Air Filters Cabin air filters help to protect your health by improving the quality of the air you breathe while in your vehicle. These filters trap a broad range of microscopic particles, harmful gases and unpleasant odors to help make your time in the car more pleasant and healthier. Regularly replacing your cabin air filter can offer relief for asthma, allergy and hay fever sufferers. It also helps to protect the performance of your air conditioning system. Particle filters with microfiber medium protect you from pollens, road dust, abraded particles as well as soot, bacteria, industrial dusts and other respirable ultra-fine particles. Carbon filters additionally protect you from exhaust gases, odours, ozone, benzene etc.
With a pollen filter and car air filter, youll experience a more pleasant and comfortable ride, especially during the summer when the pollen count is high. A fully working pollen air filter can extend the life of some of the most valuable components in your car, such as the heating and air conditioning systems. Youll find the pollen air filter in the engine compartment or cabin, and using an electrostatic paper filter to collect pollen, dirt and debris - prevents them from entering your vehicle. While most vehicles use electrostatic paper, premium models use carbon filters, which also prevent unpleasant smells and fungus from entering the cabin. Whats more, if you live in an urban or industrial area, without proper filtration you could be exposed to harmful toxic gases and air pollution that can cause headaches, nausea and fatigue. As professionals, we recommend that you replace your pollen air filter once a year - or every 10-15,000 miles. However, if where you park is surrounded by trees, ...

A method and apparatus for determining the sufficiency of refrigerant charge in an air conditioning system by the use of only two temperature measurements. The temperature of the liquid refrigerant leaving the condenser coil is sensed and the temperature of the condenser coil itself is sensed and the difference between these two measurements is calculated to provide an indication of the adequacy of refrigerant charge in the system. This process is refined by steps taken to eliminate measurements during transient operations and by filtering signals to eliminate undesirable noise. A permitted threshold of deviation is calculated by using probability theory.
Introduction. Contents Title Page Number Mainframes 2 Midrange Computers 3 Personal Computers 4 Palmtops (Personal Digital Assistants) 5 Glossary Information Technology Coursework Mainframes Mainframes have been around for decades. They were the first systems to power businesses. They often took up extremely large spaces, were expensive to buy and required large amount of power and effort, using water-cooling or air conditioning systems to keep them at optimum temperature. Mainframes are multi-user systems. They allow many users, from hundreds to thousands to work at the same time on different tasks. Mainframes use the CISC instruction set. This stands for Complex Instruction Set Computer. It uses 18 different instruction formats, with system instructions being of variable length, 16bits, 32bits and 48bits. The instructions run directly between memory and the registers, and internally within the registers and the memory. Originally the x86 was had 64kb of RAM which was expandable to 640kb. As ...

TY - JOUR. T1 - An empirical correlation and rating charts for the performance of adiabatic capillary tubes with alternative refrigerants. AU - Choi, Jongmin. AU - Kim, Yong Chan. AU - Chung, Jin Taek. PY - 2004/1/1. Y1 - 2004/1/1. N2 - With the phaseout of conventional refrigerants, refrigeration and air conditioning systems must be redesigned to improve system performance and reliability with alternative refrigerants. In this study, a generalized correlation for the prediction of refrigerant flow rate through adiabatic capillary tubes is developed by generating dimensionless parameters for operating conditions, capillary tube geometry, and refrigerant properties using the Buckingham Pi theorem. The database for the present correlation includes extensive experimental data for R12, R22, R134a, R152a, R407C, and R410A obtained from the open literature. The present correlation, which has a relatively simpler form to employ, yields a mean deviation of 5.4% and a standard deviation of 6.5% from the ...

While comfort and convenience are evident benefits of having HVAC systems in homes and businesses today, I would like to discuss another benefit of having such systems that may be less obvious to the average American. Although I am only twenty-one years old, I have had the incredible opportunity of serving as a full time caregiver for many children and adults with special needs by working at Camp Barnabas. Camp Barnabas is a summer camp for people with special needs. Having an HVAC system at a summer camp may seem like a luxury but at Camp Barnabas and in the homes of our campers, it is a necessity.. Temperature regulation is extremely important for many individuals with special needs. Numerous campers of mine dealt with epilepsy as a part of their everyday lives and having a controlled environment is essential in the prevention of seizures. Epilepsy is extremely common among people with special needs such as autism, cerebral palsy, Angelman syndrome, and a variety of other diagnoses. During hot ...

Dogs that spend most of their summer days inside are protected from many warm weather hazards, but only if the temperature inside the home remains within a healthy range. In an effort to reduce energy usage and costs, some pet owners shut off fans and air conditioning when they leave the house in the morning and turn them on when they return later in the day. However, when temperatures outside reach dangerous levels, temperatures inside the house can, too. Being shut inside a hot house can be deadly for your dog. Dogs cant sweat; they rely heavily on panting to cool themselves off. When the temperature in the environment increases, panting becomes less effective. This means that your dog could be locked inside with minimal options for cooling down. Instead of turning off the air conditioner, try leaving it on a conservative but comfortable setting (perhaps 76°F) while you are out. Make sure your dog has plenty of fresh water and consider closing curtains to reduce the heating effects of ...
