Experience, excessive

The rotors on other similar designs have experienced field vibration problems. Even a well-designed and constructed rotor may experience excessive vibrations from improper or ineffective balancing. This situation can often occur when the rotor has had multiple rebalances over a long service period and thus contains unknown balance distributions. A rotor originally balanced at high speed should not be rebalanced at low speed. 

Patients who experience excessive stress should be educated regarding the need for additional glucocorticoid replacement and prompt medical attention. 

The potent antidiuretic hormone AVP orchestrates the regulation of free water absorption, body fluid osmolality, cell contraction, blood volume, and blood pressure through stimulation of three G-protein-coupled receptor subtypes Vi-vascular types a and b, V2-renal, and V3-pituitary. Increased AVP secretion is the trademark of several pathophysiological disorders, including heart failure, impaired renal function, liver cirrhosis, and SIADH. As a consequence, these patients experience excess water retention or inadequate free-water excretion, which results in the dilution of sodium concentrations, frequently manifesting as clinical hyponatremia (serum sodium concentration <135mmol/L). This electrolyte imbalance increases mortality rates by 60-fold. Selective antagonism of the AVP V2 receptor promotes water... 

Reducing benzodiazepine use in elderly patients is important for several reasons. Long-term use of benzodiazepines can accelerate cognitive decline in elderly patients (Paterniti et al. 2002). The elderly experience excessive sedation from benzodiazepines compared with younger individuals (Lechin et al. 1996). Benzodiazepine use by elderly patients are not only associated with cognitive side effects... 

Ha is the more and HB is the less complexed host enantiomer in the aqueous phase. In the second type of experiment excess of racemic valine and optically pure (S)-[269] were distributed between two immiscible phases. In this experiment a 1 1 complex is formed in the non-aqueous phase in which L-valine dominates by an amount of 12.5% (CRFchc1j 1.28 and EDC 1.50). In terms of differences in free energy between the two diastereoisomeric complexes this means a difference in A(AG°) of 0.23 kcal mol-1 in favour of the (l)-S-[269] complex. Similar experiments have been carried out with crown ethers [270]—[280]. 

In this experiment, excess diamine is used to act as an acid acceptor. 

From the foregoing dicussion it is apparent that residuum hydroconversion processes can be influenced adversely by pore diffusion limitations. Increasing the catalyst porosity can alleviate the problem although increased porosity is usually accompanied by a decrease in total catalytic surface area. Decreasing the catalyst particle size would ultimately eliminate the problem. However, a different type of reaction system would be required since the conventional fixed bed would experience excessive pressure drops if very fine particles were used. A fluidized system using small particles does not suffer from this limitation. However, staging of the fluidized reaction system is required to minimize the harmful effects that backmixing can have on reaction efficiency and selectivity. 

Diethyl-substituted ethers 23i-k are less reactive. Ether 23k cannot be induced to rearrange, even after 72 hours. The authors speculate that this substrate may experience excessive steric compression in the envelope transition state of the [2.3] Wittig rearrangement. At higher temperatures (0°C) decomposition of the substrate and formation of multiple products is observed. 

The short-term effects are mainly those of sedation but following longer-term use accumulation may occur, particularly in the case of drugs like diazepam and chlordiazepoxide that have long half-lives due to their active metabolites. After long-term administration (weeks to months) tolerance develops. While most patients rapidly become tolerant to the sedative side effects of these drugs, some patients, particularly the elderly, experience excessive sedation, poor memory and concentration, motor incoordination and muscle weakness. In extreme cases in the elderly, an acute confusional... 

In preparative experiments, excess lead tetraacetate may be smoothly reduced by addition of a stoichiometric quantity of hydrazine in acetic acid.43 Oxalic acid is also useful,28 additional acid being added to precipitate the divalent lead formed. When no excess of tetravalent lead is present, sulfuric acid, oxalic acid, or a cation-exchange resin may be used for removing divalent lead. 

Correct choice = C. An individual with hyperthy-roidism often experiences excess heat production. 

The ion-chromatographic determination of manganese(II) with NTA masking of other metal ions looked particularly promising. Addition of a constant excess of NTA to the sample and varying the pH showed an essentially constant peak height for man-ganese(ll) between pH 2.0 and 3.0 [14]. For subsequent experiments, excess NTA was added to the sample and the pH was adjusted to 3.0. 

ThepKa values of amifloxacin, ciprofloxacin HCl and difloxacin HCl were determined by the solubility method. In these experiments, excess drug was added to a series of buffer solutions from pH 4 to 9 (pH 4-6, 0.15M acetate buffer pH 6.5-8, 0.05M phosphate buffer pH 8.5-9.0, 0.15M borate buffer jU = 0.15 with NaCl). Solutions were protected from light and allowed to equilibrate for at least 48 h in a shaking water bath at 25( 0.1) °C. The sample was filtered (5 pm), diluted with mobile phase and assayed by LC. All solubility experiments were conducted in triplicate. 

This medication should be taken every 4—6 hours to help prevent coughing but should not be taken after every cough the client could experience excessive drowsiness, constipation, and nausea.

In this experiment, excess methanol was used to shift the equilibrium toward the formation of more ester. Describe other methods for achieving the same result. 

When operators are faced with excessive task demands and their attentional resources are exceeded, they become overloaded. Mental overload therefore occurs when the demands of the task are so great that they are beyond the limited attentional capacity of the operator. Conversely, when operators experience excessively low task demands, they may experience a state of mental underload. Both conditions can be detrimental to task performance (Wilson and Rajan, 1995) because operators become less likely to attend to potentially important sources of information (Lehto and Buck, 2008).
