Recently, the best method to make the concrete industry more sustainable was using the waste materials to replace the natural resources. Currently waste paper sludge is a major economic and environmental problem in this country. In this research, the alternative method is to dwindle the usage of natural resources and the usage of cement in the construction. This method is to replace the usage of cement with the waste paper sludge ash (WPSA) and to use the recycle aggregate collected from the construction is used. The WPSA has ingredient likely cement such as self-cementation but for a low strength. The research was conducted at heavy laboratory UITM Pulau Pinang. Meanwhile, the WPSA is collected at MNI Industries at Mentakab, Pahang. The recycle aggregate is a separated half, which were fine aggregate and the coarse aggregate with the specific size. In this research, the ratio is divided into two (2) which is 1:1 and 1:2 for the aggregate and difference percentage levels of WPSA. The percentage levels of WPSA that use in this research are 10%, 20%, 30%, 40%, 50%, and 60%. A total of 36 cubes were prepared. Aim of this research is to develop a simple design approach for the mixture proportioning of WPSA and recycle concrete aggregate (RCA) within the concrete and to assess the effect of concrete mix with different percentage of WPSA and RCA ratio on the properties. It is found that the best design mix that achieves control low strength material (CLSM) is on 30% of WPSA with the ratio 1:2 on day 28 of compression test.

Despite a large variety of facilities helping to either select or manipulate data from Web interfaces, it remains diffcult to provide users with relevant scientific or technical annotations for those data. Introducing such content by hand into a Web interface is a tedious job with a risk of providing in complete or inadequate content. To overcome this diffculty, we are exploring the possibility of using the names of exposed quantities to index a text corpus. This index can be used to show the most relevant text snippets in a given context. The full text can be displayed by user request and automatically scroll down to that snippet. Our approach is based on the conversion of PDF papers into machinereadable files that are indexed by a search engine. Index entries are reported as PDF annotations that are used to control the display. This workflow has been tested on the IVOA standard corpus as a proof of concept. It has then been applied to the XMM-Newtonuser guides for our catalog interface. Finally, it has been adapted to find resources within portals exposing a lot of various data collections.

In recent years, there has great deal of attention towards customer value since the concept of value creation prompted in the Service-Dominant (S-D) Logic in marketing theory (Vargo & Lusch, 2004). With that, one of the aspects that is crucial is building and maintaining relationships that prepares customers for future co-creations. In context of higher education institutions (HEIs), students move from one life cycle stage to another, thereby needs and expectations also evolve, and when they graduate, it may dissolve. With service innovations, a smart active relationship between students and HEIs should be part of any institutions internal branding efforts. As institutions delve into relationship with students, their focus on co-creation with an aim to translate students to advocates, someone who will spread the positive word-of-mouth, defend the brand, and most importantly to feel a sense of responsibility to represent the brand, when need arises. This calls for HEIs to not only manage exchange processes in their internal branding efforts, but also focus on students’ perceived value-in-use (ViU). The purpose of this paper is to explore perceived ViU of students at private HEIs, from the effects of extra-role behavior, trust, self-brand connection and brand prominence towards influencing students to engage in advocacy behavior.

Cross-cultural differences in academic discourse as a field of applied linguistic research became mainstream at the end of the 20th century. Two fundamental concepts emerged at that period: one highlighted universal features of academic discourse, the other focused on ethnocultural peculiarities of cognitive and textual structures. Research in the field of academic discourse becomes particularly significant when applied to training and education of academic staff. Accepting the idea of universal features of academic discourse, we, however, tend to support the concept claiming that academic writing style may contain markers of ethnocultural identity of their authors. So, the aim of our research was to identify markers of ethnocultural identity in medical research texts. The study included comparative discourse analysis of research focused medical texts created by English-speaking (ES) and Russian-speaking (RS) authors. The results obtained have drawn us to the conclusion that despite universal features that scientific medical texts of the same genres share, they nevertheless manifest specific properties depending on the linguistic and cultural affiliation of their authors, i.e. markers of ethnocultural identity. This knowledge can contribute to international academic communication.

In this work we have studied a stochastic predator-prey model where the prey grows logistically in the absence of predator. All parameters but carrying capacity have been perturbed with telephone noise. The prey’s growth rate and the predator’s death rate have also been perturbed with white noises. Both of these noises have been proved extremely useful to model rapidly fluctuating phenomena Dimentberg (1988). The conditions under which extinction of predator and prey populations occur have been established. We also give sufficient conditions for positive recurrence and the existence of an ergodic stationary distribution of the positive solution, red which in stochastic predator-prey systems means that the predator and prey populations can be persistent, that is to say, the predator and prey populations can be sustain a quantity that is neither too much nor too little. In our analysis, it is found that the environmental noise plays an important role in extinction as well as coexistence of prey and predator populations. It is shown in numerical simulation that larger white noise intensity will lead to the extinction of the population, while telephone noise may delay or reduce the risk of species extinction.

This paper presents a review of literature relating to Life Cycle Costing (LCC) and Life Cycle Assessments (LCA) in Gas District Cooling plant. The gas district cooling plant uses either vapour compression process or absorption process for the chilled water generation. Both processes have impacts on the economic aspects as well as the contribution to CO 2 emissions; thus, integration of the cost and environmental analysis of both processes are necessary. An extensive body of literature exists on both subjects, however, there is very limited number of available literature on the integration of LCC and LCA. The purpose of this review is to find the most suitable optimization model which can integrate the LCC and LCA to provide the best decision in choosing the most cost-effective and environment-friendly system. This review assesses the literature from thirty-four journals, research papers, and case reports from the year 1995 to 2017. The result of this review shows that the goal programming methodology is the appropriate method for integrating LCC and LCA because it provides the optimal decision in choosing the most cost-effective, environment-friendly system for the chilled water generation.

The response of modern, commercial drawing and painting media and papers to proton irradiation has been studied in a set of 180 colour/paper combinations aimed at assessing the potential of PIXE for the characterization of modern artistic materials. In the marks that appeared on some of the materials, during and after irradiation, colour changes have been calculated and used to set the beam current and the fluence limits for safe analysis.

Vibration transmissibility is an important factor to characterize the vibration absorption performance of cushioning packaging materials during transportation. Reasonable prediction of vibration transmissibility can guide antivibration design and reduce packaging cost. As a kind of green cushioning material, paper honeycomb sandwich structure is widely used in transport packaging because of its good machinability. But at the same time, it also has strong water absorption capacity. To a great extent, the vibration transmissibility of paper honeycomb sandwich structure may be affected by ambient humidity. In this research, the vibration transmissibility of paper honeycomb sandwich structures with various structure sizes under different humidity was tested by sine frequency sweep experiments. The rule of maximal vibration transmissibility with moisture content, cell length of honeycomb, and thickness of sandwich structure was analyzed. The results show that the maximal vibration transmissibility of paper honeycomb sandwich structure increases with the increase of moisture content, cell length of honeycomb, and thickness of sandwich structure. In order to construct the relationship between maximal vibration transmissibility and various factors, the moisture content was standardized. Finally, the maximal vibration transmissibility evaluation equation of paper honeycomb sandwich structure containing standardized moisture content and size of sandwich structure was obtained, which is of some reference value for vibration prediction of paper honeycomb sandwich structures.

Flame spread over combustible solid must be precisely identify in fire hazard and this is the basic problem in fire safety engineering field. To explore the flame spread mechanism over combustible solid, the downward flame spread behaviour over paper and bagasse has been investigated in this experiment. It found that the combustion pattern for paper was slightly different from the bagasse on the front view and this was analysed through the observation. The result also showed that the flame spread rate for paper is higher compared to the flame spread rate for bagasse. It seem that, although bagasse is the combustible solid the rate of flame spread is lower and the usage of bagasse can help to control the flame spread.

The paper presents results of a comparative analysis of parameters of two kinds of solid dielectrics used in air insulation systems to prevent occurring partial discharges. The research works regarded materials made of: cellulose pressboard and aramid paper. All measurements were performed under laboratory conditions by changing the value of partial discharges generation voltage until breakdown occurred in the inhomogeneous environment that was simulated using needle-plate (made of copper) electrode system. The main contribution which resulted from studies is a statement that potential use of aramid paper as a dielectric can extend the life of a high voltage electric device as compared to standard cellulose pressboard usage due to higher electric resistances to breakdown or detection of corona voltage. Results shown that the aramid paper has greater electric resistance to breakdown in comparison to cellulose with no difference between both on detecting corona of partial discharge.
