AbstractThe effect of the biomass presence on the overall circulation velocity, the linear velocities both in the riser and the downcomer and the overall gas hold-up was studied in a three-phase internal loop airlift reactor (ILALR). The measured data were compared with those obtained using a two-phase system (air—water). All experiments were carried out in a 40 dm3 ILALR at six different biomass concentrations (ranging from 0 g dm−3 to 7.5 g dm−3), at a temperature of 30°C, under atmospheric pressure. Air and water were used as the gas and liquid model media, respectively. Pellets of Aspergillus niger produced during the fermentation of glucose to gluconic acid in the ILALR were considered solid phase. In addition, liquid velocities were measured during the fermentation of glucose to gluconic acid using Aspergillus niger. All measurements were performed in a bubble circulation regime. At given experimental conditions the effect of the biomass on the circulation velocities in the ILALR was negligible. However, increasing of the biomass concentration led to lower values of the total gas hold-up.

Randomized response (RR) is an interview technique that can be used to protect the privacy of respondents if sensitive questions are posed. This paper explains how to measure change in time if a binary RR question is posed at several time points. In cross-sectional research settings, new insights often gradually emerge. In our setting, a switch to another RR procedure necessitates the development of a trend model that estimates the effect of the covariate time if the dependent variable is measured by different RR designs. We also demonstrate that it is possible to deal with self-protective responses, thus accommodating our trend model with the latest developments in RR data analysis.

This paper describes about the phenomenon of slang language on social network, namelyfacebook and twitter. Slang in this paper belongs to sociolinguistics study, especially sociolect. This isa descriptive qualitative method, which consists of three phase: data collection, data analysis, andpresentation of the result of data analysis. The data were collected by observing the netters utterance.Data were analysed through two phases. First, analyzing the meaning of the slang. Second, wasanalysing the categories of the slang.There are four point findings in this study. Firstly, the various forms of slang expression unitsare words and phrases. Secondly, the variety of linguistic processes forming units slang expression areby adding sound, erasing sound, changing vocal, replacing consonant, shifting sound, returning sound,repeating, and changing spell. Thirdly, the source languages of various slang reference units are fromnational language, regional languages, and foreign languages. Fourthly, the communicative functionsof various units of slang expressions are informative function, directive function, expressive function,komisif function, phatic function, and poetic function.
