Abstract:
Currently, most commercial polyols used in the production of polyurethane (PU) foam are derived from petrochemicals. To address concerns relating to environmental pollution, a sustainable resource, namely, castor oil (CO), was used in this study. To improve the production efficiency, sustainability, and compressive strength of PU foam, which is widely used as an impact-absorbing material for protective equipment, PU foam was synthesized with CO-based multifunctional polyols. CO-based polyols with high functionalities were synthesized via a facile thiol-ene click reaction method and their chemical structures were analyzed. Subsequently, a series of polyol blends of castor oil and two kinds of castor oil-based polyols with different hydroxyl values was prepared and the viscosity of the blends was analyzed. Polyurethane foams were fabricated from the polyol blends via a free-rising method. The effects of the composition of the polyol blends on the structural, morphological, mechanical, and thermal properties of the polyurethane foams were investigated. The results demonstrated that the fabrication of polyurethane foams from multifunctional polyol blends is an effective way to improve their compressive properties. We expect these findings to widen the range of applications of bio-based polyurethane foams.

Abstract:
Based on thermodynamic considerations and experimental data on isothermal compression of elastomeric foams, a simple equation of state of flexible polymeric foams was developed. The developed equation of state is, in fact, a simple universal function relating the thermodynamic properties of the material of which the skeleton of the foam is made and the foam porosity. It was shown that the Hugoniot adiabat of foams, whose porosity is less than 0.3 and which are exposed to moderate shocks, could be expressed in a form similar to that of bulk solids, i.e., D = Co + Su, where D is the shock front velocity, Co is the speed of sound, u is the particle velocity and S is the maximum material compressibility.

Abstract:
Addition of fillers in polyurethane foams enhances the mechanical properties of polymeric foams. However, fillers can be loaded to a certain extent, as higher percentage of fillers in polymeric foam causes structural instability leading to the collapse of foam. In this article, we report the use of hollow glass microspheres as a possible co-filler which enables higher loading of nano-clay in flexible polyurethane foam. It has been observed that the structural and mechanical properties of nano-clay-loaded foams were found to cause instability at 5 wt% loading of nano-clay. Therefore, upon addition of hollow glass microspheres in 5 wt%, nano-clay-loaded polyurethane foam shows remarkable enhancement in terms of stability and mechanical properties of the resultant foams. A 100-fold increment in tensile strength has been observed for 2 wt% hollow glass microspheres and 5 wt% nano-clay-loaded flexible polyurethane foams as compared to conventional (unloaded) polyurethane foams.

Abstract:
Foams were prepared from hydrophobically modified ethyl(hydroxyethyl) cellulose (EHEC), methyl nanocellulose, and native microfibrillated cellulose (MFC). Their film- and foam-forming abilities, stabilities, and suitabilities for foam coating on different substrates were investigated. The role of EHEC as a polymeric stabilizing agent was also studied. The EHEC-MFC foams showed greater stability and water-holding ability under pressurized dewatering than MFC foams prepared in the presence of a surfactant. A foam could be created with methyl nanocellulose without any foaming agent. Selected nanocellulose gels and foam formulations were used to coat various substrates. The surface was efficiently closed by gel and foam coatings prepared from the methyl nanocellulose and EHEC solutions, which was ascribed to good coating holdout. Coatings on papers with different levels of smoothness/density and hydrophobicity/ hydrophilicity confirmed that foam-substrate interactions affected the coat quality. The air permeance was reduced by 99% and 64% with a methyl nanocellulose coating and an EHEC-MFC coating, respectively. An EHEC-MFC coating created a hydrophobic surface on a hydrophilic substrate, and methyl nanocellulose improved the oil resistance even at a low coat weight.

Full text
Abstract:
Ambient temperature self-blowing tannin–furanic foams have been prepared by substituting a great part—even a majority—of furfuryl alcohol with humins, a polyfuranic material derived from the acid treatment at high temperature of fructose. Closed-cell foams were prepared at room temperature and curing, while interconnected-cell foams were prepared at 80 °C and curing, this being due to the more vigorous evaporation of the solvent. These foams appear to present similar characteristics as other tannin–furanic foams based only on furfuryl alcohol. A series of tannin–humins–furfuryl alcohol oligomer structures have been defined indicating that all three reagents co-react. Humins appeared to react well with condensed tannins, even higher molecular weight humins species, and even at ambient temperature, but they react slower than furfuryl alcohol. This is due to their high average molecular weight and high viscosity, causing their reaction with other species to be diffusion controlled. Thus, small increases in solvent led to foams with less cracks and open structures. It showed that furfuryl alcohol appears to also have a role as a humins solvent, and not just as a co-reagent and self-polymerization heat generator for foam expansion and hardening. Stress-strain for the different foams showed a higher compressive strength for both the foam with the lowest and the highest proportion of humins, thus in the dominant proportions of either furfuryl alcohol or the humins. Thus, due to their slower reactivity as their proportion increases to a certain critical level, more of them do proportionally participate within the expansion/curing time of the foam to the reaction.

Full text
Abstract:
This study was focused on evaluating the suitability of a wide range of lignins, a natural polymer isolated from different plant sources and chemical extractions, in replacing 20 wt.% of petroleum-based polyol in the formulation of PU flexible foams. The main goal was to investigate the effect of unmodified lignin incorporation on the foam’s structural, mechanical, and thermal properties. The hydroxyl contents of the commercial lignins were measured using phosphorus nuclear magnetic resonance (31P NMR) spectroscopy, molar mass distributions with gel permeation chromatography (GPC), and thermal properties with differential scanning calorimetry (DSC) techniques. The results showed that incorporating 20 wt.% lignin increased tensile, compression, tear propagation strengths, thermal stability, and the support factor of the developed PU flexible foams. Additionally, statistical analysis of the results showed that foam properties such as density and compression force deflection were positively correlated with lignin’s total hydroxyl content. Studying correlations between lignin properties and the performance of the developed lignin-based PU foams showed that lignins with low hydroxyl content, high flexibility (low Tg), and high solubility in the co-polyol are better candidates for partially substituting petroleum-based polyols in the formulation of flexible PU foams intended for the automotive applications.

Abstract:
Aqueous foams are macroscopically homogeneous complex fluids composed of co-existing gas and liquid phases. A hierarchy of structure and self-organization at progressively smaller length scales is ultimately responsible for the unique material properties of foams, and is shown schematically in Figure 1. A key feature of this microstructure is the continuous random network of liquid which typically occupies 1–10 vol% and separates the tightly packed gas bubbles. As shown by the photographs in Figure 2, the average bubble diameter can vary widely from about 10 μm to 1 cm, while the average bubble shape can vary from nearly spherical to nearly polyhedral, depending on the liquid volume fraction. At the smallest structural scale, surface active molecules are preferentially adsorbed at the gas/liquid interfaces and give rise to several physical-chemical effects that deter the coalescence of neighboring bubbles and thereby lend stability to the foam. However, the delicate structure formed by gas bubbles packed in a continuous liquid phase is not truly stable with either time or applied forces. This article reviews recent progress in understanding the structural response of aqueous foams to temporal and mechanical perturbations.

Abstract:
The thesis aimed to explore the experience of sibling aggression. Previous research has focused on the prevalence, predictors and effects of siblings engaging in aggressive behaviours with one another. However, there is a distinct lack of evidence that has explored the experience of this form of family violence. The thesis made an original contribution to knowledge by exploring the impact of multiple forms of family violence on the use of aggression between siblings, asking victims and/or perpetrators of these aggressive behaviours about their retrospective experiences and developing a quantitative measure of sibling aggression. A mixed methods approach was taken, employing archival, qualitative and quantitative techniques. More specifically, an archival study of the 1975 National Family Violence Survey (NFVS; Straus, Gelles & Steinmetz, 1980) was conducted to explore the relationship between co-occurring aggression and sibling aggression. The findings revealed that as co-occurring verbal or physical aggression increased within the family environment, the frequency of both physical and verbal aggression between siblings also increased. Following this, semi-structured interviews were conducted with victims and/or perpetrators of sibling aggression to explore this form of family violence further, particularly in relation to how aggression differs from play fighting, and the role of normalisation. The interviews identified that although aggressive acts of behaviour may look similar to those for play fighting, the motivations and functions of them differ. More specifically, play fighting was an enjoyable and game-like behaviour for children, whereas sibling aggression often occurred in response to a build-up of negative emotions, to maintain dominance or to overcome verbal arguments. The normalisation of sibling aggression was also important, particularly in relation to how parents responded to their children using aggressive behaviours with one another. In the third study of this thesis, a questionnaire, the Experiences of Sibling Aggression (ESA) scale, was developed to not only test the themes derived from the interviews on a larger scale, but to also explore differences between victims and perpetrators of this form of family violence. Amongst a sample of participants recruited through social media and on a university campus, a four-factor model of the ESA scale was validated, with subscales that reflected; play fighting, sibling aggression, normalisation and dominance. The ESA scale was also shown to increase the likelihood of predicting mutual sibling aggression, with these participants scoring higher on the sibling aggression subscale (concerning the use of aggression to overcome negative emotions and solve arguments) when compared to a control group of participants who had no previous involvement in aggression with their sibling. These studies have provided several key contributions to knowledge of sibling aggression. Firstly, they have highlighted the relationship between sibling aggression and multiple forms of family violence. Secondly, they have enhanced the understanding of how play fighting and sibling aggression are conceptualised and differ from one another, highlighting the importance of parents in intervening in these behaviours. Finally, the ESA scale was developed, specifically for the exploration of this form of family violence. The implications of the findings involve the need to consider contextual factors rather than only the individual acts of aggression between siblings. It can be concluded that sibling aggression is a serious form of family violence serving a different function when compared to play fighting among children. This should be reflected in both practice and future research.

Abstract:
The aim and objectives of this work are to synthesize cobalt-based hydroxides and transition metal disulphides composites with carbon materials such as graphene foam and activated carbon by a facile and environmentally friendly hydrothermal technique for energy storage application. Because faradaic materials suffer from poor electrical conductivity and low electrochemical stability, while carbon materials are known to have good electrical conductivity and electrochemical stability, the combination of the two materials to make hybrid material should be able to improve the electrochemical properties of the composite material. Morphological, structural, surface area and compositions properties of the produced materials were evaluated and characterized using methods such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), N2 adsorption-desorption isotherm (BET), Fourier transformation infrared spectroscopy (FTIR) and Raman spectroscopy. Electrochemical characterization involved cycling voltammetry (CV), galvanostatic charge-discharge (GCD), electrochemical impedance spectroscopy (EIS) and cycling life were carried out in two (asymmetric device) and three-electrode configurations using 6 M KOH aqueous electrolyte and they all showed excellent electrochemical performance. For instance the asymmetric devices based on CoA-LDH/graphene foam//AEG gave specific capacitance of 101.4 F g-1 with a maximum energy density of 28 Wh kg-1 and a corresponding power density of 1420 W kg-1 at a current density of 0.5 A g-1 , VS2//AC gave specific capacity of 155 F g-1 and high energy and power densities of 42 Wh kg-1 and 700 W kg-1 respectively at current density of 1 A g-1.and MoS2_150 mg GF //AEG gave high specific capacitance of 59 F g-1 with maximum energy and power densities of 16 Wh kg-1 and 758 W kg-1 respectively at a current density of 1 A g-1 respectively . All these results showed the great potential of the hybrid materials derived from the incorporation of cobalt based hydroxides and transition metal disulphides with carbon for supercapacitor application.<br>Thesis (PhD)--University of Pretoria, 2016.<br>Physics<br>PhD<br>Unrestricted

Abstract:
Val av sparform vid ägande i aktier har blivit allt mer aktuellt sedan det år 2012 infördes en ny sparform. Beskattningsskillnader mellan de tre nuvarande sparformerna har lett till konfunderade och osäkra aktieägare. Att optimalt val av sparform beror på ett flertal föränderliga och individuella faktorer gör att ett generellt och entydigt svar saknas. Denna rapport ska på uppdrag av ett mindre förvaltningsföretag med anledning av ovanstående, ta fram ett matematiskt verktyg vilket illustrativt ska rekommendera val av sparform utifrån olika antaganden. Rekommendationerna ska leda till att aktieportföljens avkastning efter skatt maximeras. Vidare ska rekommendationer kring implementation av den matematiska modellen i företagets verksamhet ges, där fokus ligger på ökat kundvärde. Modellen som togs fram kan utefter aktieägarens förväntade årsavkastning, förväntad prognos över statslåneräntan, placeringshorisont samt individuellt courtage rekommendera vilken sparform som ska väljas, samt när och till vilken sparform ett byte ska ske, för att därigenom maximera avkastningen efter skatt, givet att byte av sparform enbart tillåts vid årsskiftet. Genom att utgå från co-operation vid implementation av den matematiska modellen i verksamheten kan det för två specifika kundsegment leda till ökat kundvärde vid kundmöten.<br>Selecting the form of savings on share ownership has become increasingly relevant since the year 2012, when a new form of savings was launched. Taxation differences between the three current saving forms have led to confused and uncertain shareholders. The optimal choice of the form of savings depends on several evolving and individual factors, making that no general and simple answer could be given. This report was assigned by a small shareholder management company by reason of the above, to provide a mathematical tool which illustratively should recommend the selection of savings form, based on different assumptions. The recommendations should lead to a maximized share portfolio return after tax. Furthermore, recommendations regarding implementation of the mathematical model in the company's operations should be given, focused on enhanced customer value. The model that was developed should be based on the shareholder's expected annual return, expected forecast of government interests, investment horizon and individual brokers courtage, recommend which form of saving to be selected, regarding when and to what form of saving to move to, thereby maximizing the return after tax, assuming that the changed form of savings only to be allowed at end of year. By base the work on co-operation along the implementation of the mathematical model for the business, it can for two specific customer segments lead to added customer value at client meetings.

Full text
Abstract:
Scrivere di Islam. Raccontare la diaspora (Writing About Islam. Narrating a Diaspora) is a meditation on our multireligious, multicultural, and multilingual reality. It is the result of a personal and collaborative exploration of the necessity to rethink national culture and identity in a more diverse, inclusive, and anti-racist way. The central part of this volume – both symbolically and physically – includes Shirin Ramzanali Fazel’s reflections on the discrimination of Muslims, and especially Muslim women, in Italy and the UK. Looking at school textbooks, newspapers, TV programs, and sharing her own personal experience, this section invites us to change the way Muslim immigrants are narrated in scholarly research and news reports. Most importantly, this section urges us to consider minorities not just as ‘topics’ of cultural analysis, but as audiences and cultural agents. Following Shirin’s invitation to question prevailing modes of representations of immigrants, the volume continues with a dialogue between the co-authors and discusses how collaboration can be a way to avoid reproducing a ‘colonial model’ of knowledge production, in which the white male scholar takes as object of analysis the work of an African female writer. The last chapter also asserts that immigration literature cannot be approached with the same expectations and questions readers would have when reading ‘canonised’ texts. A new critical terminology is needed in order to understand the innovative linguistic choices and narrative forms that immigrant writers have invented in order to describe a reality that has lacked representation or which has frequently been misrepresented, especially in the discourse around the contemporary Muslim diaspora.

Abstract:
Interest in noise control has been growing in recent years and efforts are under way to improve the acoustic performance of existing sound absorbers and also to replace the non-recyclable ones with environmentally friendly materials. Present study describes the research on fabrication, improvement of acoustic absorption and enhancement of mechanical strength of bio-based open-cell foams. Through this study, highly porous open-cell Polylactide (PLA) foams were fabricated by a new fabrication method combining particulate leaching technique and compression molding. Foamed structures were fabricated with PLA and Polyethylene glycol (PEG) with salt as the particulate. Pore size of the foam was controlled by salt particulates and higher interconnectivity was achieved by the co-continuous blending morphology of PLA matrix with water-soluble PEG. As a result of novel secondary porous structure, acoustic performance of PLA foams was successfully improved. One issue with application of bio-based open-cell foams is the weak structure. To improve mechanical characteristics of PLA foams, different polymer composites of PLA and Polyhydroxyalkanoate (PHA) were foamed and characterized in terms of acoustic performance, mechanical properties and foam morphology. Polymers used in this study are bio-based which is of great importance considering huge amount of foams used as acoustic absorbers in various industries.

Abstract:
Mathematical models and numerical predictions of heat conduction and laminar natural convection in ice-water systems containing porous metal foams are presented, in the context of computationally convenient two-dimensional steady-state problems with rectangular calculation domains. The Darcy-Brinkman-Forchheimer equations were used to model momentum transfer in the liquid-water-metal-foam region. For modeling the heat transfer, volume-averaged equations governing two intrinsic-phase-average temperature fields were used: one for the metal foam and the other for the water (solid or liquid). The following improvements are proposed: novel expressions for the interfacial (metal-water) heat transfer coefficient in both the convection and conduction regimes; and effective thermal conductivity correlations that provide consistency between the formulations of one-temperature and two-temperature models in the limit of local thermal equilibrium. A well-established fixed-grid, co-located, finite volume method (FVM) was adapted and used for the numerical solutions. The proposed models and FVM were used to solve the test and demonstration problems involving conduction and laminar natural convection in ice-water-aluminum-foam systems contained in rectangular enclosures. The findings and results of these investigations are presented and discussed in this paper.
