Key Variables

A highly specific, accurate, and simple RP-HPLC technique was developed for the real-time quantification of domperidone (DOMP) and lansoprazole (LANS) in commercial formulations. Chromatographic studies were performed using a Luna C8(2), 5 μm, 100Å, column (250 × 4.6 mm, Phenomenex) with a mobile phase composed of acetonitrile/2 mM ammonium acetate (51:49 v/v), pH 6.7. The flow rate was 1 mL·min−1 with UV detection at 289 nm. Linearity was observed within the range of 4–36 µg·mL−1 for domperidone and 2–18 µg·mL−1 for lansoprazole. Method optimization was achieved using Box-Behnken design software, in which three key variables were examined, namely, the flow rate (A), the composition of the mobile phase (B), and the pH (C). The retention time (Y1 and Y3) and the peak area (Y2 and Y4) were taken as the response parameters. We observed that slight alterations in the mobile phase and the flow rate influenced the outcome, whereas the pH exerted no effect. Method validation featured various ICH parameters including linearity, limit of detection (LOD), accuracy, precision, ruggedness, robustness, stability, and system suitability. This method is potentially useful for the analysis of commercial formulations and laboratory preparations.

New Equation

In general, this new equation is significant for designing and operating a pipeline to predict flow discharge. In order to predict the flow discharge, accurate determination of the flow loss due to pipe friction is very important. However, existing pipe friction coefficient equations have difficulties in obtaining key variables or those only applicable to pipes with specific conditions. Thus, this study develops a new equation for predicting pipe friction coefficients using statistically based entropy concepts, which are currently being used in various fields. The parameters in the proposed equation can be easily obtained and are easy to estimate. Existing formulas for calculating pipe friction coefficient requires the friction head loss and Reynolds number. Unlike existing formulas, the proposed equation only requires pipe specifications, entropy value and average velocity. The developed equation can predict the friction coefficient by using the well-known entropy, the mean velocity and the pipe specifications. The comparison results with the Nikuradse’s experimental data show that the R2 and RMSE values were 0.998 and 0.000366 in smooth pipe, and 0.979 to 0.994 or 0.000399 to 0.000436 in rough pipe, and the discrepancy ratio analysis results show that the accuracy of both results in smooth and rough pipes is very close to zero. The proposed equation will enable the easier estimation of flow rates.

This paper highlights the association of language use skills with self-confidence as a contributing factor to the determination of expatriate self-adaptability in a foreign cultural environment. The objective of this study was to examine whether the skills of using the local language of the host country are considered as a universal skill requirement for improvisation and self-skills among expatriate academics in Malaysian Public Universities. Utilisation of qualitative methods of semi-structured interviews on 35 lecturers with international staff status in four Malaysian Public Universities which were subsequently processed by inductive analysis for dominant and subdominant thematic classifications. The findings prove that the informants utilised language proficiency as a backup to recognise their ability to respond to external stimuli, thus producing positive value to themselves. The proactive process is done by trying to find answers to change and self-transformation while in a foreign country. Studies linking the elements of confidence and self-identity skills among expatriates are often highlighted, but the approach taken is to put the advantage to be utilised on the part of the organisation and not expatriates as the subject of the study. Therefore, the results of this study fulfil the search for answers regarding their identity as an expatriate, including exploring foreign cultures, releasing the culture of the country of origin, developing a network of contacts and assessing their potential and ability to deal with the challenges of life abroad. The direction of future research refers to the addition of value in the expatriate management literature by making basic concepts of interaction such as language proficiency as an element capable of increasing self-confidence and sketching the career development of self-initiated expatriates.

Receiving Water

It is proposed that in the future only site-specific and problem-related measures should be applied to solve the combined sewer overflow problem. Based on experience in Switzerland a procedure is developed to plan technically and ecologically optimised measures to protect urban receiving waters during wet weather. This procedure is based on results of a field study (the Fehraltorf/Switzerland case) carried out by a multidisciplinary research team. The most important stages of the procedure can be described bythe definition of site-specific ecological objectives,the determination of a few key variables that have significant influence on the ecological state of the receiving water and that can be modified with some of the site-specific measures below,measurement, observation, and calculation of these variables,choice of site-specific measures against wet weather pollution problems (in catchment, sewer system, and receiving water), andrecommendation of measures and their priorities, based on predicted cost and effectiveness with respect to the variables above. The results of the case study demonstrate the necessity of the multidisciplinary approach that treats the urban catchment, the urban drainage system, and the receiving water as one single system. Since urbanised areas continue to grow and since the reconstruction of old depreciated sewer systems is a major technical and economical challenge, the proposed modification of the planning concept may lead towards improved drainage systems, requiring appropriate investment, and causing less serious damage to the environment.

Undissolved air in oil causes various problems for hydraulic systems and strongly decreases the efficiency of the system. In this respect, the hydraulic reservoir as the only component that performs the function of releasing the accumulated air from the system is relevant. In recent years, the air release efficiency in hydraulic reservoirs has been studied both experimentally and in simulation. However, in none of the according studies dynamically changing flow conditions have been considered. In this paper, the air release behaviour of a hydraulic reservoir is investigated through simulation, considering the dynamics of the system. The developed multiphase CFD model utilizes the open-source CFD tool, OpenFOAM®, based on a Lagrangian Particle Tracking (LPT) within an Eulerian phase. The simulations have been conducted varying the key variables such as oil flow rate and air load at the inlet of the reservoir and yield the air content at the outlet.

Construction Strategies

After 20 years of green chemistry research, a complete algorithm for the determination of material and synthetic strategy efficiencies for synthesis plans to any chemical target has been achieved. This paper presents the first announcement of a comprehensive database consisting of green metrics calculations for 1060 plans to 220 targets of interest to the chemical industry in the following categories: commodity industrial chemicals, pharmaceuticals, agrichemicals, dyestuffs and colorants, natural products, flavorings, fragrances, and sweeteners, and molecules of theoretical interest. Data mining of the original literature covered the period 1828–2010. A summary of trends in achieving green chemistry strategies is presented, including an unbiased method of ranking plans using a suite of parameters, ring construction strategies, and implications on the development of new kinds of smart structure search databases. The take-home message is that targeted optimization is a multivariable problem that requires synergistic maximization and minimization of key variables. Problems in the reporting of chemical syntheses in scientific journals and patents are discussed as well as setting guidelines for their standardization and normalization. The merits of spreadsheet tools are presented from decision making in route selection all the way to fast and accurate proofreading of the final plan chosen.

Internal Mixer

Abstract The flow visualization method of studying internal mixing has been shown to be a powerful tool for determination of the critical factors influencing flow and mixing efficiency. Correlation of visualizations with results obtained for “practical” rubber mixing confirms the validity of the method for the prediction of flow in conventional mixing operations. Fill factor is identified as one of the key variables influencing mixing uniformity. At this stage it is not possible to make general recommendations since only limited studies were carried out. However, from the dependence of mix uniformity on fill factor derived from a B Banbury having two-wing rotors, fill factors of 0.7–0.8 are shown to give the best results. This range of fill factors provides an adequate and continual filling of the region in front of the rotor tip and ensures that the high stresses required for the fracture of particle material aggregates are generated. It also permits the formation of voids behind the rotor tips. Such voids appear to be essential for the disordering of streamline flow patterns and for promoting effective axial tranfer of material.
