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.

Observational data on Galactic supernova remnants III: The supernova remnants within l = 270°-360° [PDF]

Serbian Astronomical Journal, 2004
We have collected all the available data of Galactic supernova remnants given in the literature. The data of Galactic supernova remnants located in the Galactic longitude interval l=270°-360°in all the spectral bands are represented in this work. We have

How Tycho Brahe’s recordings in 1572 support SN 1572 as a type I(a) supernova

Frontiers in Astronomy and Space Sciences, 2023
The 450th anniversary of the discovery of the SN 1572 supernova event was celebrated in 2022. A closer look at the historical development of the field of supernova astronomy reveals the scientific importance of Tycho Brahe’s 1572 observations of this ...

iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova [PDF]

Science, 2016
Multiple images of a type Ia supernova General relativity indicates that any sufficiently massive object bends the path of light passing by it. This effect is known as gravitational lensing. Goobar et al.

Star Formation as Seen by Low Mass Stars

Acta Polytechnica CTU Proceedings, 2014
Using the Hubble Space Telescope (HST) we have characterised and compared the physical properties of a large sample of pre-main sequence (PMS) stars spanning a wide range of masses (0:5 - 4Mʘ), metallicities (0:1 - 1 Zʘ) and ages (0:5 - 30 Myr).

Luminous Supernovae [PDF]

Science, 2012
Stellar Explosions Stars that are born with masses greater than eight times that of the Sun end their lives in luminous explosions known as supernovae. Over the past decade, access to improved sky surveys has revealed rare types of supernovae that are much more luminous than any of those that were known before.

On the occurrence of fast neutrino flavor conversions in multidimensional supernova models [PDF]

Physical Review D, 2018
The dense neutrino medium in a core-collapse supernova or a neutron-star merger event can experience fast flavor conversions on time/distance scales that are much smaller than those of vacuum oscillations.

The high energy X-ray probe (HEX-P): science overview

Frontiers in Astronomy and Space Sciences
To answer NASA’s call for a sensitive X-ray observatory in the 2030s, we present the High Energy X-ray Probe (HEX-P) mission concept. HEX-P is designed to provide the required capabilities to explore current scientific questions and make new discoveries ...

Assessing the Performance of the Phase Difference Bathymetric Sonar Depth Uncertainty Prediction Model

Remote Sensing, 2022
Realistic predictions of the contribution of the uncertainty sources affecting the quality of the bathymetric measurements prior to a survey is of importance. To this end, models predicting these contributions have been developed.

Supernova Rates [PDF]

International Astronomical Union Colloquium, 1996
Extragalactic supernova rates are reviewed. The main uncertainties in calculated rates are due to (1) the influence of the (still poorly known) luminosity function of supernova of a given type on “control times”, to (2) uncertain corrections for possible inclination - dependent bias in supernova discovery probabilities, and (3) interstellar absorption.
