Legacy waste from the decommissioned A-1 nuclear power plant in the Slovak Republic is scheduled for immobilisation within a tailored alkali borosilicate glass formulation, as part of ongoing site cleanup. The aqueous durability and characterisation of a simulant glass wasteform for Chrompik III legacy waste, was investigated, including dissolution experiments up to 112 days (90°C, ASTM Type 1 water). The wasteform was an amorphous, light green glassy product, with no observed phase separation or crystalline inclusions. Aqueous leach testing revealed a suitably durable product over the timescale investigated, comparing positively to other simulant nuclear waste glasses and vitreous products tested under similar conditions. Iron and titanium rich precipitates were observed to form at the surface of monolithic samples during leaching, with the formation of an alkali deficient alteration layer behind these at later ages. Overall this glass appears to perform well, and in line with expectations for this chemistry, although longer-term testing would be required to predict overall durability. This work will contribute to developing confidence in the disposability of vitrified Chrompik legacy wastes.

Introduction Celebrities are actively capitalizing on their fame and credibility by launching their own brand extensions which are heavily promoted on Instagram. This situation is especially prevalent in Malaysia among many local Malay ‘celepreneurs’. While consumers’ constant involvement with a celebrity on Instagram is believed to result in the purchase of celebrity branded products, the central question of how a causal variable such as Instagram involvement has an effect on the outcome of purchase has been less explored in contemporary studies. The role of celebrity adulation and style conformity in the context of celebrity branding-cum-entrepreneurship deserves much attention given the strong influence celebrities exert on young consumers in this digital era of accessible information. Research framework Given the admiration that young consumers have towards the celebrities they follow on Instagram, celebrity worship, in both pathological and non-pathological form, is believed to be a crucial link between their involvement with the social media and their desire to imitate their favourite celebrity’s style. Eventually this paves the way for the purchase of celebrity brand products given that getting the products is an avenue for the young consumers to attain their celebrities’ style. Therefore in this study, four variables that mediate the relationship between Instagram involvement and purchase of celebrity branded products are examined: celebrity worship as manifested across three varying levels particularly entertainment-social (lowest form of worship); intense-personal (mid-level); borderline pathological (highest level); and style conformity. Method Data was collected from 226 Malaysian women of Malay ethnicity who are active Instagram users and fall under the technology-savvy Millennial segment using a self-administered questionnaire. This segment of consumers is technology savvy and has personalities and lifestyles (Gurau, 2012). They also tend to imitate their favourite celebrity in contrast to their male counterparts (Djafarova & Rushworth, 2017). Measures for the mediating variables were derived from McCutcheon et al.’s (2002) Celebrity Worship Scale and Park and Yang’s (2010) items on celebrity style conformity. A five-point scale (1=strongly disagree to 5=strongly agree) was utilized to capture the responses to the variables measured. Analysis and results Serial multiple mediation testing was applied on the data using variance-based structural equation modelling. The multiple mediation analysis showed that of all the three levels of celebrity worship which mediate the link between Instagram involvement and style conformity, only celebrity worship (entertainment-social) was found to be a significant mediator between Instagram involvement and style conformity (Indirect effect=0.127; t-value= 3.285, 95% Boot CI: LL=0.059, UL=0.216). In addition, the presence of a serial mediation was detected for the link between Instagram involvement-celebrity worship (entertainment-social)-style conformity-purchase of celebrity brand products (Indirect effect=0.04; t-value=2.954, 95% Boot CI: LL=0.02, UL=0.08). Conclusion The serial mediation testing in this study has demonstrated that celebrity worship and style conformity serve as the missing link between the involvement-purchase relationship. Furthermore, the multiple mediation testing has shown that only celebrity worship at the basic level functions as a mediator. The findings of this study imply that the use of Instagram is indeed a compelling marketing communication tool that fosters the purchase of celebrity brand extensions. Constant involvement in Instagram by following the celebrity, liking, reposting, commenting or hashtagging on the celebrity’s account builds a keen sense of devotion for the celebrity whereby the individual will constantly watch, read and learn about the celebrity. This then heightens the user’s desire to emulate the style of the celebrity which may well lead them to purchase the celebrity’s products in an effort to imitate the celebrity’s look and demeanour. strong desire for and high willingness to spend on branded products that match their

Polarbear is a ground-based experiment located in the Atacama desert of northern Chile. The experiment is designed to measure the Cosmic Microwave Background B-mode polarization at several arcminute resolution. The CMB B-mode polarization on degree angular scales is a unique signature of primordial gravitational waves from cosmic in ation and B-mode signal on sub-degree scales is induced by the gravitational lensing from large-scale structure. Science observations began in early 2012 with an array of 1,274 polarization sensitive antenna-couple Transition Edge Sensor (TES) bolometers at 150 GHz. We published the first CMB-only measurement of the B-mode polarization on sub-degree scales induced by gravitational lensing in December 2013 followed by the first measurement of the B-mode power spectrum on those scales in March 2014. In this proceedings, we review the physics of CMB B-modes and then describe the Polarbear experiment, observations, and recent results.

The Eclipsing Binaries Minima (BIMA) Monitoring Project is a CCD-based photometric observational program initiated by Bosscha Observatory - Lembang, Indonesia in June 2012. Since December 2012 the National Astronomical Research Institute of Thailand (NARIT) has joined the BIMA Project as the main partner. This project aims to build an open-database of eclipsing binary minima and to establish the orbital period of each system and its variations. The project is conducted on the basis of multisite monitoring observations of eclipsing binaries with magnitudes less than 19 mag. Dierential photometry methods have been applied throughout the observations. Data reduction was performed using IRAF. The observations were carried out in BVRI bands using three dierent small telescopes situated in Indonesia, Thailand, and Chile. Computer programs have been developed for calculating the time of minima. To date, more than 140 eclipsing binaries have been observed. From them 71 minima have been determined. We present and discuss the O-C diagrams for some eclipsing binary systems.
