Purpose The purpose of this paper is to determine the influence of service quality and university image on student satisfaction and student loyalty. Design/methodology/approach This study employed a set of survey instrument adapted from previous studies. The construct of the service quality consisted of 12 indicators, one of which was originally designed by the researcher, and the rest were adapted from other researchers. For the construct of university image, there were five indicators, while the rest were designed by the researcher. There were six indicators of construct student satisfaction, while the other three were designed by the researcher. Lastly, the construct student loyalty consisted of five indicators, three of which were originally designed by the researcher. All of those constructs used seven-point Likert scale scoring, which ranged from 1= strongly disagree to 7= strongly agree. Findings The findings of this study are as follows: the result of the data analysis has confirmed the existence of a positive and significant influence of service quality on student satisfaction, there is a positive and significant influence of student satisfaction on student loyalty, there is no positive or significant influence of service quality on student loyalty, and university image has a positive and significant influence on both student satisfaction and student loyalty. Originality/value The originality of this study has been confirmed, considering the fact that only few studies on service quality in education field were conducted. In this study, researchers were interested in developing the service quality based on five dimensions. This model have been applied by a number of researchers. Unfortunately, some other researchers showed their disagreements upon the use of only these five dimensions in the research in the field of education, and they suggested that more appropriate dimensions should be applied.

In response to the COVID-19 pandemic, single-use disposable masks saw a dramatic rise in production. Facial masks that are not properly disposed of will expose the environment to a form of non-biodegradable plastic waste that will take hundreds of years to degrade. Therefore, recycling such waste in an eco-friendly manner is imperative. Fibered or shredded waste masks can be used to make green concrete that is an environmentally friendly solution to dispose the facial masks. This study prepared six classes of concrete samples, three of which contained fibers from masks and three of which contained shredded masks at the ages of seven days and 28 days. The results show that in the seven-day and 28-day samples, mask fiber added to the mixes resulted in increased compressive strength. For seven-day and 28-day samples, the compressive strength increased by 7.2% and 10%, respectively. Despite that, the results of the shredded mask addition to concrete indicate that the increase in shredded mask volume has a minor impact on the compressive strength of the seven-day samples. An increase in shredded mask from 0.75 to 1% increased 28-day compressive strength by 14%. However, the compressive strength of the mask fiber decreased by 8 after 1% volume. According to a thermal analysis of 28-day concrete samples, as the fiber percentage increases, the mass loss percentage increases. The mass loss rate for samples containing fibers is higher than that for samples containing shredded mask pieces. In general, based on the results mentioned above, the use of fiber in concrete in its fiber state enhances its strength properties. As a result, using shredded mask pieces in concrete leads to better curing due to the reduction of residual capillary pore water loss in construction materials.

This research aims to examine the TQM application in education using SERVQUAL and the quality function deployment (QFD) based on the students' perspectives. Globalization in the current technological era requires every country to be able to face increasingly fierce competition. Indonesia ranked 41st below Malaysia, Thailand, and Singapore out of 137 countries in 2017-2018 Global Competitiveness Index. Quality human resources are the only choice to win the competition. TQM can be used to produce the right quality standards to produce competent and competitive graduates. This study aims to discuss how the application of TQM in education uses SERVQUAL and also the quality function deployment (QFD) based on student perspectives. The results showed that the quality of technology is one of the important elements that are highly expected by students but have not been fulfilled by the university.

This study aimed to understand whether there is a reciprocal relationship between student satisfaction and university image along with assessing the effect of service quality on student satisfaction, student loyalty, trust, and student motivation in universities in Riau. In the cross sectional, questionnaire-based study; a study instrument having six variables: five endogenous variables were trust (Y1), student satisfaction (Y2), university image (Y3), student loyalty (Y4), and student motivation (Y5) and one exogenous variable, namely, service quality (X1) was used. All variables were assessed by the 7-point Likert response scale. Structural equation modeling (SEM) and analysis of variance (ANOVA) were used as the analysis tools. Majority of the responders belonged to the age group of 20–22 years. Students in the age group of 20–22 years were nearing the end of their Diploma and Bachelor programs; this group of students had a long experience of service quality provided by the university. The responses to the survey questions regarding service quality, student satisfaction, trust, university image, and loyalty varied in different students’ groups based on the age and course of study. However, no effect of gender on the responses was observed in the present study.

Normal human blood lymphocytes in RPMI 1640 media with 20% human serum (pH 7.6) were exposed to temperatures of 37-45°C. The processes of cell death were studied by phase contrast and electron microscopy, by time-lapse cinemicrography, and by serial counts of viable and dead cells. Dead cells showed two distinctive morphologic types: cells with pyknotic nuclei and \"condensed\" cells. Examination by phase microscopy revealed that dead cells with pyknotic nuclei had uniformly dark nuclei which were either ring-shaped, crescentic, or round; a moderate amount of clear cytoplasm; and a thin plasma membrane. When examined by electron microscopy, the pyknotic nucleus was seen as a homogenous mass of electron-dense granules without a normal architectural pattern or nuclear membrane. Electron microscopy showed the condensed cell characterized by electron-opaque cytoplasm, a dense nucleus with normal architectural features, and multiple cytoplasmic vacuoles. Serial counts of viable and dead cells showed that exposure of lymphocytes to 43 or 45°C killed cells primarily by the process resulting in condensed cells; at 37, 41, and 42°C, lymphocytes died primarily by pyknosis. The findings support the hypothesis that different mechanisms killed the cells above and below the critical temperature of 43°C.
