Let $G$ be a group, we say that $G$ satisfies the property $mathcal{T}(infty)$ provided that, every infinite set of elements of $G$ contains elements $xneq y, z$ such that $[x, y, z]=1=[y, z, x]=[z, x, y]$. We denote by $mathcal{C}$ the class of all polycyclic groups, $mathcal{S}$ the class of al…
Batako dikenal sebagai salah satu jenis produk yang sering digunakan dalam mendirikan sebuah bangunan yang terbuat dari campuran beberapa material. Jumlah material yang digunakan sangat berpengaruh terhadap kualitas dari batako itu sendiri. Penelitian ini berfokus pada simulasi bentuk profil batako dari material concr…
This assessment explores the current analysis methodologies of various external and MOOSE-based tools available at the Idaho National Laboratory to model pebblebed reactor multiphysics phenomena.The study involves three MOOSE-based, coupled codes: 1) MAMMOTH for reactor physics, 2) Rattlesnake for neutron transport an…

Significance and Use 5.1 A number of types of jaw crushers have been used for laboratory abrasion tests, see Refs (1-5)4 and a limited amount of data has been published (6-10). With emphasis on the crusher described in Section 6, this test method ranks m
Small is the very best interdisciplinary forum for all experimental and theoretical aspects of fundamental and applied research at the micro and nano length scales.With an ISI Impact Factor of 9.598, and publishing every week with papers online in advance of print, Small is your first-choice venue for topquality commu…

Energy is one of the basic requirements in our daily lives. The world’s energy demand is continuously increasing over the years due to the ever-increasing growth in the human population as well as economic development. At present, approximately 90% of energy demand are fulfilled by fossil fuels. With the rising demand…
Pure aluminum metal manufactured using Cold Isostatic Press (CIP) bears the properties of Structural Reactive Material (SRM) and has the capacity to increase lethality due to the continuous combustion of the fragments after explosion. This thesis focuses on the enhanced lethality and reactivity produced by replacing c…
The crystal nucleation pathway is of huge importance for tailoring the semicrystalline morphology of polymers. For demonstration, the cover images show samples of the biopolymer poly (l-lactic acid) crystallized at 130 °C (bottom row) and 140 °C (top row), with the crystallization temperature approached by direct cool…
This thesis explores the thermal conditioning of three different legacy nuclear wastes requiring additional treatment. For the first waste stream (encapsulated Magnox drums showing evidence of internal corrosion) it was found that thermal conditioning passivates the reactants responsible for the underlying corrosion r…
Partial discharge (PD) localization has been performed on a periodic or on a request basis to assess the health of high-voltage (HV) systems mainly due to lack of feasibility of techniques for continuous monitoring and localization. Advancements in the field of communication technology have made it possible to detect…
I would like to thank my directors, Jolanta Sapieha and Ludvik Martinu, for providing me with valuable insights and support throughout my project, as well as giving me the opportunity to participate in this project which has travelled me more kilometers than any other undertaking in my life.In addition, I would like t…
The relationship between radiogenic ⁴He in zircon, and its associated radiation damage to the crystal lattice, have been of scientific interest since the earliest attempts at geochronology, and remain an active topic of research today in the pursuit of understanding the timing of low-temperature geological processes.…
In this work X-ray reflectivity (XRR) was implemented as a characterization technique to study very thin films produced at CENIMAT. Three groups of samples were analysed: thin films of Ta2O5, thin films Ta2O5 mixed with SiO2 (TaSiO) and thin films of zinc-tin oxide (ZTO). Spectroscopic ellipsometry was used as a compl…
A web is defined as a material whose length is very large compared to its width and the width is much greater than the thickness. Web material includes paper, fabric, metal, plastic film and composites. Nonwoven fabric is a fabric-like material made from long fibers that are bonded together by chemical, mechanical, he…

Commercial films are generally made of polyolefins, often using a blend of two different polyolefins.Specifically, low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) are blended due to the mechanical strength of LLDPE and the processability of LDPE.However the behaviour of these blends is unpr…
