This paper describes a wireless sensor network prototype with the use of reconfigurable hardware for airliner cabin environment research. Commercial airplane passengers and crews breathe a mixture of outside and re-circulated air, similar to many homes and offices. But the cabin environment is unique, due to the proximity of the passengers, the need for cabin pressurization, the low humidity, a...

Halliday’s Systemic Functional Linguistics (SFL) has stood the test of time as a model of text analysis. The present literature contains a plethora of studies that while taking the ‘clause’ as a unit of analysis have put into investigation the metafunctions in research articles of a single field of study or those of various fields in comparison. Although ‘clause complex’ is another unit of SF a...

AIMS To investigate whether length of employment as a cabin attendant was related to breast cancer risk, when adjusted for reproductive factors. METHODS Age matched case-control study nested in a cohort of cabin attendants. The cases were found from a nationwide cancer registry (followed up to end of year 2000) and the reproductive factors (age at first childbirth and number of children) from...

in this paper a survey to determine the spring and damper settings of itm285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. analysis has been done in terms of root mean square acceleration response (rmsar) in one-third-octave band and international standard organization (iso). optimization was performed using particle swarm optimization (pso) method on a 2...

Escherichia coli cells are shown to be attracted to the l-amino acids alanine, asparagine, aspartate, cysteine, glutamate, glycine, methionine, serine, and threonine, but not to arginine, cystine, glutamine, histidine, isoleucine, leucine, lysine, phenylalanine, tryptophan, tyrosine, or valine. Bacteria grown in a proline-containing medium were, in addition, attracted to proline. Chemotaxis tow...

In nature, living creatures are affected by several stimuli simultaneously. The response of living creatures to stimuli is called taxis. In order to reveal the principles of taxis behavior in response to complex stimuli, we simultaneously applied photostimulation and electric stimulation perpendicularly to a Volvox algae solution. The probability distribution of the swimming direction showed th...

Ensuring comfortable climatic conditions for operators in the cabin of technological machines is an important scientific and technical task affecting operator health. This article implements numerical analytical modeling thermal state vehicle cabin, considering external airflow internal ventilation. A method calculating heat transfer coefficients a multilayer wall air under forced convective ex...

Partial body cryotherapy cabins most often use liquid nitrogen as their cryogenic fluid, which raises safety concerns during operation. In this study, an innovative cabin design is presented, featuring electric cooling system suitable for producing cold air at −30 °C. The geometry of the designed evaluated by a thermodynamic modeling aims optimizing circulation flows inside cabin. numerical stu...
