Evaluation of Sealing Strength in Multilayer LLDPE Packaging for Impact-Resistant Rice Pouches

Jurnal Kimia Sains dan Aplikasi
In this study, we evaluate the mechanical integrity, thermal stability, and impact resilience of three different laminated polymer materials—PA/LLDPE, MDO-PE/LLDPE, and BOPE/LLDPE—to assess their suitability for rice packaging applications.

A New Determination of the High Redshift Type Ia Supernova Rates with the Hubble Space Telescope Advanced Camera for Surveys [PDF]

We present a new measurement of the volumetric rate of Type Ia supernova up to a redshift of 1.7, using the Hubble Space Telescope (HST) GOODS data combined with an additional HST dataset covering the North GOODS field collected in 2004.

Presupernova Eruptions Triggered by Sudden Energy Deposition in Low-mass Core-collapse Supernova Progenitors

The Astrophysical Journal
In low-mass core-collapse supernova (SN) progenitors, nuclear burning beyond oxygen can become explosive under degenerate conditions, triggering eruptive mass loss before the final explosion.

VLBI observations of SN2011dh: imaging of the youngest radio supernova

We report on the VLBI detection of supernova SN2011dh at 22GHz using a subset of the EVN array. The observations took place 14 days after the discovery of the supernova, thus resulting in a VLBI image of the youngest radio-loud supernova ever. We provide

The Relation between Helium White Dwarf Mass and Orbital Period under Two Types of Opacity

The Astrophysical Journal
Helium white dwarfs (He WDs) are end products of low-mass red giant donors in close binary systems via stable mass transfer or common envelope evolution.

Revised Lens Model for the Multiply-Imaged Lensed Supernova, "SN Refsdal", in MACS J1149+2223

We present a revised lens model of MACS J1149+2223, in which the first resolved multiply-imaged lensed supernova was discovered. The lens model is based on the model of Johnson et al. (2014) with some modifications.

Supernova Burst and Diffuse Supernova Neutrino Background Simulator for Water Cherenkov Detectors

The Astrophysical Journal
If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations ...
