In the search for more accurate ways to determine intraocular pressure, the Halberg applanation tonometer may represent an alternative to the Schi0tz tonometer for routine screening pressure measurements. Although between 100 to 150 measurements are generally required to gain proficiency with the Halberg, the instrument is accurate in patients with normal corneas even with very abnormal scleral...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
Aims: Noise is considered the most harmful physical agents in the workplace which exposure to it can cause the harmful physical and psychological effects on worker. Since the best noise control measures is to reduce or limit the at the source, the purpose of this study was to assess the noise pollution and determine the dominant sound source in an Air production plant of a Petrochemical industr...
The results of this study indicated that the synoptic patterns that lead to heavy rainfall in 22 March 1996, 24 mar 1995 and 17 November 1994 in the northern portion of FARS province includes: the low pressure that located in eastern part of Mediterranean and Black sea and southern part of Caspian Sea that created by trough that located at the middle level of atmosphere. In addition to this low...
the present study aimed to evaluate the antimicrobial activity of a hetroalkyl oximec synthetic compoundderivative (benzophenone o-4-bromoethyl oxime) against two gram positive and three gram negative bacteria.the antibacterial characteristic of this compound was shown using the circular zone diameter of bacterial growthinhibition by disk-diffusion method. in addition, the random amplified poly...
at many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. in such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. in this research work a new a...
Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does...
conclusions the mgap scoring system can be used as an appropriate scoring system to predict mortality in triage trauma patients. results patients were divided into three groups : scores of less than 18, 18 - 22 and greater than 22; in which the mortality rates were 75.2%, 9.5% and 0.1%, respectively (p < 0.0001). the best cut-off point was 22 in our study, and the mgap scoring system had 93.7% ...
Traveling by air, especially long distance, is not a natural activity for humans. The combination of long flight duration, limited space, and an unusual cabin environment in terms of air pressure, humidity, and continuous noise causes physical and psychological discomfort and even stress for a large group of passengers. Excessive stress may cause some passengers to become aggressive and overrea...
