As an essential electrolyte for the human body, the potassium ion (K+) plays many physiological roles in living cells, so the rapid and accurate determination of serum K+ is of great significance. In this work, we developed a solid-contact ion-selective electrode (SC-ISE) using MoS2/Fe3O4 composites as the ion-to-electron transducer to determine serum K+. The potential response measurement of MoS2/Fe3O4/K+-ISE shows a Nernst response by a slope of 55.2 ± 0.1 mV/decade and a low detection limit of 6.3 × 10−6 M. The proposed electrode exhibits outstanding resistance to the interference of O2, CO2, light, and water layer formation. Remarkably, it also presents a high performance in potential reproducibility and long-term stability.

60 rats received 60 or 204 differential instrumental conditioning trials under 3-, 19- or 43-hr. water deprivation, followed by 60 reversal trials. In early acquisition speeds to both S+ and S—were greater with increased deprivation, but the subsequent onset of differentiation was most rapid in groups run at 43-hr. deprivation, this produced by their slower running to S—. Reversal performance was but little affected by deprivation, not was there any interaction between deprivation level and amount of prior training in the determination of reversal performance. Reversal performance was related to amount of prior training in a complicated fashion depending on the stimulus, the point of response measurement and the stage of training: First, number of prior reinforcements increased both start and run speeds to the old positive stimulus in early reversal but had no effect on start speeds and decreased run speeds in later reversal; second, number of prior non-reinforcements did not affect speed acquisition to the new positive stimulus.

Measurement Results

Frequency response analysis (FRA) is a popular method for assessing a transformer’s mechanical condition. The paper proposes a new method for interpreting the frequency response measurement results. The currently used numerical indices only give one value, which may be misleading in the analysis, while the proposed frequency response quality index (FRQI) tool analyses three separate features in the whole frequency range. The applied numerical calculations technique allows for estimations of not only the values of the average quality indices, but also locally for given frequency ranges of the analysed spectrum. It allows for determination of the problems that can be found in the active part of a transformer. The presented results come from three transformers, representing cases of typical faults. Two of them are from industry, while one was used for deformational tests in laboratory conditions. The proposed FRQI method showed its usefulness in FRA test results analysis and may be introduced into the automated assessment of such data. Each of the component parameters is sensitive to other types of differences observed between the compared frequency response curves, and may be used as a good quality detection tool.

Iad Framework

Land use over its capability led to a watershed criticality. It was hypothesized by a lack of coordination in formulation and implementation of land use institution in watershed management. Catur watershed is one of critical watershed in Indonesia. This study aimed to formulate the development strategies of land use institution in Catur watershed. Institution analysis and development (IAD) framework was used to formulate it. The results showed land use problems in managing Catur watershed were 1) the overlap in determination of area function, 2) lack of socialization and supervision in implementing the regulation, and 3) a forum of coordination that has not been effective in accommodating the interests of each actors. Therefore, need an identification and involvement all the actors on conference of development planning (Musrenbang) to achieve a good governance.
