    No full text
    Organic–inorganic nanohybrids-based polymer nanocomposites are made up of two different components, and these hybrids attained great attention over last decades due to their diversified framework and fascinating features. These nanohybrids possess synergistic characteristics of both organic and inorganic substances. Different synthetic routes are used to synthesize these materials with enhanced morphology, tunable features, and fine nanostructures. This chapter focuses on various synthetic routes for fabrication of organic–inorganic-based nanopolymeric composites. Synthetic strategies and protocols of different routes have been described in details. We have also discussed the advantages and limitations of all synthetic methods in details.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Aerospace Manufacturing Technologie

    A Case Study on Management of Calcaneal Spur with Ḍimād (Paste) of Polyherbal Unani Medication

    No full text
    Objective- To evaluate the effectiveness of Dimād therapy, a traditional Unani treatment method, in alleviating heel pain caused by calcaneal spur, and to explore its potential as a safe, affordable alternative to conventional therapies Design - This is a single-case report detailing the clinical presentation, diagnosis, and treatment of a patient with a calcaneal spur using Dimād therapy within the Unani medical framework. Intervention - The patient underwent Dimād therapy, which involves the local application of heat to the affected heel area, based on the principles of Unani medicine, which aim to restore humoral balance and eliminate morbid materials. Treatment was tailored according to the six essential factors of life in Unani medicine. Main Outcome Measure- Reduction in heel pain, improvement in mobility, and overall patient satisfaction following completion of Dimād therapy. Results- The patient experienced significant relief from heel pain and reported enhanced mobility following the course of Dimād therapy. No adverse effects were observed, and the therapy was well tolerated. Conclusion- This case suggests that Dimād therapy may be an effective and non-invasive approach to managing calcaneal spurs. It supports the Unani view that addressing underlying humoral imbalance and lifestyle factors can contribute to sustainable pain relief. Further clinical studies are needed to validate these findings. Keywords- Unani medicine, Waja-ul-Aqib, heel pain, traditional therapy, Ilaj bit tadbee

Kerron tekemistäni taiteellisista ja teknisistä ratkaisuista sekä siitä, miten ne liittyvät alkuperäisen tarinan hahmoon ja miten rakentamani nuken hahmo kehittyi työskentelyni aikana.In my thesis I write about constructing Pinocchio-puppet for Kaarina Youth Theatre. I write about the history and story of Pinocchio and also about the author, Carlo Collodi. I tell about the artistic and technical solutions which led to these conclusions. I explain how the history and fame of Pinocchio affected and supported these processes

    Fabrication and Nanomechanical Characterization of Thermoplastic Biocomposites Based on Chemically Treated Lignocellulosic Biomass for Surface Engineering Applications

    Diverse applications of polymeric materials have prompted development of eco-friendly, efficient, and economical materials. These characteristics can be obtained by incorporating appropriate fillers in the polymeric matrix. The objective of this work is to investigate impact of aqueous glycerol (Gly) treated rice husk (RH) on surface mechanical properties of produced biocomposites. RH was treated with aqueous Gly (75 wt%) and compounded with low density polyethylene (LDPE) at different loadings (10, 20, and 30 wt%). The resulting mixture was thermally pressed in molds to fabricate biocomposites. Surface mechanical properties such as elastic modulus, hardness, creep rate, and plasticity of biocomposites reinforced with untreated and treated RH were investigated using nanoindenter. Experimental values depicted that hardness (H) and elastic modulus (Es) of treated biocomposites were higher than untreated ones. Treated biocomposites showed the noticeable improvement in elastic modulus by 24 and 37% compared to untreated biocomposites at 20 wt% loading and neat LDPE, respectively. Reductions in the creep rate by 20 and 14% were observed for untreated and treated biocomposites, respectively, in comparison to the neat LDPE. H/E ratio was increased by 23 and 18% for treated and untreated biocomposites, respectively, as compared to virgin LDPE. Furthermore, mechanical and structural properties of untreated and treated RH are reported based on nanoindentation response and Fourier transform infrared spectroscopy (FTIR) techniques The study indicated that aqueous glycerol pretreatment can partially strip off non-cellulosic constituents from lignocellulose matrix to generate cellulose-rich pulp for engineered composite applications.Rivers, Ports, Waterways and Dredging Engineerin

    Report on 12th International Conference on Concrete Pavements: “Making Waves with Durable and Resilient Concrete Pavements”

    No full text
    This report summarises the attended presentation of 12th International Conference on Concrete Pavement (ICCP) that was held virtually from 27th of September to 1st of October 2021, with the theme “Making Waves with Durable and Resilient Concrete Pavements”. The 12th ICCP focussed on information about new technologies related to the design, construction and rehabilitation of various concrete pavements. The 12th ICCP was initially scheduled for August 2020 in Minnesota, USA, but the global COVID-19 pandemic has continued to spread. Considering health measures around the world, international travel feasibility, and limited travel for U.S. state agencies, the 12th ICCP organizing committee worked diligently to find the best solution for conference attendees, venues, and the society itself. Ultimately, the best decision was made for all involved to hold the 12th ICCP 2021online. The international conference was hosted by a virtual campus named “The Aggregate”, consisted of three auditoriums (cement, water and sand ) and two conference halls (Conference hall A and B). The forum had offered 698 participants from 30 countries and 38 U.S. states, including 96 presentations (both live and pre-recorded) in 24-technical sessions, workshops on a broad range of concrete pavements, the student pitch networking event andinteractive networking opportunities include public and private chat. Different presentations were being given simultaneously in different sessions. I had selected below eighteen presentations as these presentations' goals were more understandable and intresting. This report summarises presentations that the author of this report had attended during 12th ICCP.BVFF: Effektiv reparation av betongväga

    Physico-chemical analysis of semi-crystalline PEEK in aliphatic and aromatic solvents

    No full text
    Polyether ether ketone (PEEK) is a semi-crystalline thermoplastic polymer having excellent mechanical and thermal properties. Exposure of this polymer to aliphatic and aromatic solvents can lead to degradation or swelling of the polymeric material. The present work described the plasticization and stability analysis of semi-crystalline PEEK under different aromatic and aliphatic solvent environment. A variety of solvents (acetone, benzene, benzyl alcohol, chloroform, methanol, and toluene), based on their Hildebrand’s Solubility Parameter, were chosen for investigation. The physico-chemical characteristics of virgin and treated polymeric samples were investigated using Gas Chromatography–Mass Spectrometry (GC–MS), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Fourier Transform Infrared Spectroscopy (FTIR) techniques. The results indicated that the solvent exposure did not significantly affect the thermal behavior and chemical structure of the polymer. However, it seems that certain components of the polymer were leached into the solvent phase as revealed by the GC–MS analysis. The present study identified PEEK as a potentially suitable polymer for the applications where high resistance to aliphatic and aromatic solvents is needed.Rivers, Ports, Waterways and Dredging Engineerin
