Cystic fibrosis (CF) is an autosomal recessive condition caused by the mutation of the cystic fibrosis transmembrane regulator gene (CFTR) on chromosome 7. Although it primarily affects the respiratory and gastrointestinal tracts, it can also involve other organs. It may also cause electrolyte and acid base disturbances, rarely the mode of presentation. This can result in difficulty in making a...

It is shown that many dynamic tests and measurement technologies base on a changing measurement equation and that internal and external disturbances may change the dynamic functional of the same object and that the reaction of measurement transducer (measurement channel) changes not only in dependence on type of loads. The reasons are given which cause methodical metering errors and make it dif...

In the preceding article (1) it was pointed out that one of the electrolyte disturbances most frequently encountered in the serum of patients with nephritis with uremia was deficiencyof the total electrolyte (base) concentration of the serum and that this was apparently instrumental in the determination of acidosis (reduction of bicarbonate) in a certain and rather large proportion of cases. It...

BACKGROUND Disorders of acid-base involve the complex interplay of many organ systems including brain, lungs, kidney, and liver. Compensations for acid-base disturbances within the brain are more complete, while limitations of compensations are more apparent for most systemic disorders. However, some of the limitations on compensations are necessary to survival, in that preservation of oxygenat...

The camera stabilizer stabilizes the camera’s line of sight by isolating the camera from the model uncertainties, disturbances of operating environment and system movements. This paper presents a voltage-base optimal adaptive fuzzy sliding mode control for camera stabilizer. In this proposed control method, a voltage-base sliding mode controller is applied. But unfortunately, undesirable ...

Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...

Human management activities have altered the frequency and intensity of ecosystem disturbance often with enormous impacts on landscape structure and composition. One additional and under-appreciated way in which humans have altered disturbance regimes is through the introduction of invasive non-native species, themselves capable of modifying existing disturbance regimes or introducing entirely ...
