This document summarizes an experimental investigation into the mechanical properties of recycled high density polyethylene (HDPE). Virgin HDPE was tested, as well as HDPE that was recycled up to three times. The recycling process involved crushing and blending the plastic. Tests measured density, tensile strength, elastic modulus, elongation, impact strength, and creep recovery. Results showed that with increased recycling, density and elastic properties generally decreased while tensile strength increased. Mixing recycled and virgin HDPE found that properties remained stable with higher recycled content, except for a drop in impact strength and recovery ability. The study aims to better understand how mechanical properties are affected by repeated recycling and content of recycled plastic.

A review on synthesis and their antibacterial activity of silver and selenium...SSR Institute of International Journal of Life Sciences
Antibacterial agents are very important in the textile industry, water disinfection, medicine, and food packaging. Organic compounds used for disinfection have some disadvantages, including toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. This review focuses on the Preparation and their potential with good antimicrobial activity of Ag-NPs and Se-NPs against biofilm forming S. aureus. Such improved antibacterial agents locally destroy bacteria, without being toxic to the surrounding tissue. We also provide an overview of opportunities and risks of using NPs as antibacterial agents. In particular, we discuss the role of Ag-NPs and Se-NPs materials. Several manufactured nanoparticlesparticles with one dimension less than 100 nm are increasingly used in consumer products. At nano size range, the properties of materials differ substantially from bulk materials of the same composition, mostly due to the increased specific surface area and reactivity, which may lead to increased bioavailability and toxicity. Thus, for the assessment of sustainability of nanotechnologies, methods of manufacturing Nanoparticles, properties have to be studied.
The formation of nanoparticle and physiochemical parameters such as pH, monomer concentration, ionic strength as well as surface charge, particle size and molecular weight are important for drug delivery. Further, these nanoparticles have the capability to reverse
multidrug resistance a major problem in chemotherapy. Well-established therapies commonly employed in cancer treatment include surgery, Chemotherapy, immunotherapy, and
radiotherapy. The silver nanoparticles might be involved in neutralizing these adhesive substances, thus preventing biofilm formation. Selenium is also one of essential trace elements in the human body and has great importance in nourishment and medicine. Medicaldiagnostic field also developed to use the selenium nanoparticles and also studies on the increase efficiency of glutathione peroxidase and thioredosin reductase.Recommended

Nanoparticles Methods for Nanoparticles Synthesis Overview
Nanoparticles exist in several different morphologies such as spheres, cylinders, platelets, tubes etc. The word nanoparticles are used to describe a particle with size in the range of 1nm to 100nm, at least in one of the three possible dimensions. In this size range, the physical, chemical and biological properties of the nanoparticles changes in fundamental ways from the properties of both individual atoms molecules and of the corresponding bulk materials. The enormous diversity of the nanoparticles arising from their wide chemical nature, shape and morphologies, the medium in which the particles are present, the state of dispersion of the particles and most importantly, the numerous possible surface modifications the nanoparticles can be subjected to make this an important active field of science now a days.

The problem encountered in this paper is to design a robust, feedback-based improved control system for the plant that involves systematic uncertainty. This paper proposes a fault estimation algorithm based on iterative learning control. This algorithm is constructed through an optimization function to prove the robustness and convergence of the algorithm. Through linear matrix inequality (LMI), the observer gain matrix and iterative learning parameter matrix in the algorithm are solved. The two comprehensive parameters in LMI represent the parameter selection in the two specifications to make selected adjustments in learning and control. A numerical example shows the improvement process and the effectiveness of these methods. Through LMI techniques, we have obtained satisfactory results and controller stability and robustness against fault-tolerant control. Lastly, the simulation results show the effectiveness and accuracy of the proposed algorithm.

This document discusses maintaining healthy indoor relative humidity levels in rural residential buildings using sustainable construction materials. It analyzes indoor humidity variations in model houses built with mud block walls and rat trap bond brick walls using computational fluid dynamics (CFD) simulations. The simulations examine how indoor relative humidity depends on heat gain from roofs and walls due to solar radiation. The results show mud block houses experience greater indoor relative humidity variations than brick houses. Maintaining indoor relative humidity between 40-70% is recommended for health, as this range minimizes survival of airborne bacteria and viruses while avoiding issues like mold growth. Ventilation is important to balance indoor moisture generation and removal.

BIOMEDICAL APPLICATIONS OF CERAMIC NANOMATERIALS: A REVIEW
A variety of Nano-biomaterials are synthesised, characterised and tested to find out their potentialities by global scientific communities, during the last three decades. Among those, nanostructured ceramics, cements and coatings are being considered for major use in orthopaedic, dental and other medical applications. The development of novel biocompatible ceramic materials with improved biomedical functions is at the forefront of health-related applications, all over the world. Understanding of the potential biomedical applications of ceramic nanomaterials will provide a major insight into the future developments. This study reviews and enlists the prominent potential biomedical applications of ceramic nanomaterials, like Calcium Phosphate (CaP), Tri-Calcium Phosphate (TCP), Hydroxy-Apatite(HAP), TCP+HAP, Si substituted HAP, Calcium Sulphate and Carbonate, Bioactive Glasses, Bioactive Glass Ceramics, Titania-Based Ceramics, Zirconia Ceramics, Alumina Ceramcis and Ceramic Polymer Composites.
Hip Bone replacement
This document discusses materials used for hip bone replacements. Titanium carbide is highlighted as a promising material due to its mechanical properties, biocompatibility, and ability to osseointegrate with bone. Titanium carbide is synthesized from ilmenite ore and carbon powder then sintered with diamond powder to form a super hard ceramic. Its future potential lies in advanced orthopedic applications like joint replacements due to its strength, inertness, and direct bonding with bone at the nanoscale through osseointegration.
Applications of chemistry in everyday life
The document discusses how the properties of materials, including their intermolecular and intramolecular forces of attraction, can be manipulated by scientists and engineers to create substances tailored for different applications. It provides examples of how materials are designed for uses in medicine like implants and prosthetics which require biocompatibility and strength, electronics which feature polar components, sports equipment which must be durable, and construction supplies which need to withstand forces through strong bonding. The document emphasizes how understanding molecular interactions allows the production of customized materials that improve lives by enabling medical devices, consumer products, and engineered structures.

Mergesort
The document discusses the merge sort algorithm. Merge sort works by recursively dividing an unsorted list in half until each sublist contains one element, and then merging the sublists back together in sorted order. This can be done by dividing the list, sorting each half via recursive calls, and then using a merge process to combine the now-sorted halves into a fully sorted list. The document provides examples of merging two sorted lists and walking through the full merge sort process on a sample input list. It analyzes the time complexity of merge sort as O(n log n) and discusses in-place versus double-storage implementations.
JDBC Architecture and Drivers
This document discusses JDBC architecture and driver types. It introduces JDBC as an API that allows Java applications to connect to databases. The JDBC architecture involves using driver classes like DriverManager and Connection to communicate with a database through a specific driver. There are four types of JDBC drivers: type 1 uses JDBC-ODBC bridge, type 2 uses native database APIs, type 3 uses a middleware, and type 4 is a pure Java driver that connects directly to the database.
Modulation Techniques
The document discusses three types of modulation techniques: amplitude modulation, frequency modulation, and phase modulation. Amplitude modulation varies the amplitude of the carrier signal while keeping frequency and phase constant. Frequency modulation varies the frequency of the carrier signal while keeping amplitude and phase constant. Phase modulation varies the phase of the carrier signal while keeping amplitude and frequency constant. Each modulation technique has advantages and disadvantages related to power consumption, bandwidth requirements, and applications such as radio waves, television, and satellite communication.
Top 10 Hadoop Shell Commands
The document discusses Hadoop shell commands for interacting with the Hadoop Distributed File System (HDFS). It provides the syntax and examples of 10 common commands: 1) hadoop version, 2) mkdir, 3) ls, 4) cat, 5) mv, 6) cp, 7) rm, 8) put, 9) get, and 10) tail. These commands allow users to create directories, list contents, display files, move/copy files, remove files, upload/download files between local file system and HDFS, and view the last lines of a file.
Arrays and Pointers
This document discusses pointers and arrays in computer programming. It defines pointers as variables that contain the memory address of another variable. Arrays are collections of similar data items with a fixed size. Pointer variables can contain the address of an array element. An array name is like a constant pointer. The document provides an example of an integer array and using a pointer variable to traverse the array elements by address. It also discusses using pointers to dynamically allocate arrays of strings to save memory compared to fixed-length character arrays.
Java string , string buffer and wrapper class
The document discusses Java strings and wrapper classes. It provides examples of creating and manipulating strings using the String, StringBuffer, and StringBuilder classes. It also discusses the eight primitive wrapper classes in Java and examples converting between primitive types and their corresponding wrapper classes.

Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
