A presente pesquisa trata do estudo de cenários regionais de drenagem urbana das principais sub-bacias pertencentes à área urbana de São Carlos/SP e da aplicação de incentivos ambientais em escala de lote. As projeções temporais realizadas dizem respeito às mudanças do uso e ocupação do solo para os anos de 2025, 2050, 2075 e 2100. Os cenários de uso e ocupação do solo têm como base os estudos referentes ao Millennium Ecosystem Assessment (Global Orchestration, Order from Strength, Adapting Mosaic e TechnoGarden) e sua adequação na escala local, para macrodrenagem urbana, proposta por Mendiondo (2005). Os eventos pluviométricos utilizados nas simulações dos cenários, por sua vez, foram selecionados em função das condições de umidade antecedente. Para os cenários propostos, foram avaliadas variações dos regimes hidrológico e hidráulico através de curvas de permanência em alguns pontos ao longo da parte de montante da sub-bacia do Monjolinho. Ainda, em escala de lote, é proposta uma metodologia de incentivos ambientais com base no armazenamento potencial de água no lote e na vazão máxima instantânea, para cada cenário estudado. A metodologia proposta de incentivo ambiental revela-se de simples aplicação por parte de órgãos públicos e de rápida obtenção dos resultados. Embora os cenários propostos sejam fictícios, os custos estimados (R$/\'M POT.2\') são aplicáveis para condições atuais. / This research discussed the study of regional scenarios of urban drainage of the main sub-basins belonging to the urban area of San Carlos/SP and the application of environmental incentives in lot scale. The projections of time made are related to changes of use and occupation of land for the years of 2025, 2050, 2075 and 2100. The scenarios of use and occupation of land are based on the studies concerning the Millennium Ecosystem Assessment (Global Orchestration, Order from Strength, Adapting Mosaic and TechnoGarden) and its appropriateness in the local scale, to urban macrodrainage, proposed by Mendiondo (2005). The rainfall events used in the simulations of scenarios were selected for the conditions of background humidity. For the proposed scenarios have been evaluated changes in the hydrological and hydraulic systems through remain curves in some points along the top part of sub-basin of Monjolinho. Still, in scale of lot, is proposed a methodology for environmental incentives based on the potential for water storage in the lot and the maximum instantaneous flow for each scenario studied. The proposed methodology of environmental incentive appears to be the simple application by public agencies and quickly get the results. Although the proposed scenarios are fictitious, the estimated costs (R$/\'M POT.2\') are applicable to current conditions.

The Third Chapter: The aim of this research is to study individual choices of precau- tionary saving and long-term care spending when an individual faces the uncertainty of after-retirement health shocks. To do this, an improved two-period life-cycle model is employed. This paper also explores how individual choice affects economic development and capital accumulation in an overlapping generation economy. The study shows that the rise in the possibility of getting after-retirement health shocks will result to an increase in long-term care expenditure and the level of precautionary saving. The steady state will also increase in this case. The Fourth Chapter: The increasing and intensifying long-term care (LTC) demand brings great financial pressures for both governments and individuals. From the public perspective, the underlying economic question is how adequate real resources can be re- distributed to support long-term care need and how efficient the policies targeting is. As many LTC policies are accessed through means tests, individuals saving behaviour can be affected. This paper examines and compares the welfare effects that different means- tested policies have on individuals. We did this by embedding life-cycle models with after-retirement health shocks. Means-tested policies of long-term care, one with a top- up choice, and one without, were then simulated. The results show that the means test regime with a top-up option can bring a higher social welfare. Under this scheme, a higher means test threshold can decrease societys dependency on a social benefit system and increase social welfare. The Fifth Chapter: Attendance Allowance and Disability Living Allowance are the dis- ability cash benefits provided for people who are over 65 in the U.K. As the government plans to divert more public resource from these benefits to means-tested local care ser- vices, it is important to understand the effects and targeting of these cash benefits first. Using the survey data from English Longitudinal Study of Ageing, this study examines the relationship between the receipt of disability cash benefits and recipients’ character- istics among those who are over 65 in England. Although income is not a key factor to decide on the receipt of the benefits in the criteria, the results show that it still has a self- selection process where the benefits are given to those who are both most in need and on low incomes.

A short wakeful rest immediately after new learning boosts verbal memory retention over several minutes. This memory boost is observed both in healthy people and in patients with amnesia, including patients with amnestic mild cognitive impairment (aMCI) and mild Alzheimer’s Disease (AD). Wakeful resting is hypothesized to boost memory by protecting the memory consolidation (strengthening) process from interfering sensory stimulation. The effect of a short wakeful rest immediately after new learning has, to this stage, been tested only over standard retention intervals (≤1 hour). The objectives of this PhD project were to: 1.) examine whether a short wakeful rest immediately after learning boosts memory over a longer retention interval (7 days) in healthy older adults (Experiment 1, Experiment 2) and aMCI/mild AD patients (Experiment 3) 2.) investigate whether intentional rehearsal is necessary and sufficient to boost memory during wakeful rest, over both short-term (15-minute) and long-term (7-day) delays (Experiment 4, 5 and 6) 3.) compare the effect of a short post-learning rest on retention as assessed via cued recall, free recall and recognition, both over short delays (15 minutes) and long delays (7 days and 4 weeks) (Experiments 4,5 and 7) 4.) examine whether a short wakeful rest immediately after learning boosts retention of real-life-like stimuli (face/name paired associates) in healthy older adults and aMCI/mild AD patients (Experiment 8, Experiment 9) In order to accomplish these aims, several samples of healthy adults and amnesic patients were tested, utilising a range of experimental designs. In all experiments, the learning of new material was followed immediately (i) by a brief wakeful rest, or (ii) by a cognitively demanding task. A delayed memory test took place after a range of intervals. The results demonstrate a pronounced memory enhancement over 15-30 minutes and 7 days in aMCI/mild AD patients via a short post-learning wakeful rest. A similar, albeit less pronounced 7-day memory benefit via post-learning wakeful rest was found in healthy older adults. Moreover, it was found that post-learning wakeful resting boosted 7-day recognition memory in healthy older adults, even when the learned material could not be rehearsed intentionally. Although intentional rehearsal did provide a 7-day memory improvement in healthy older adults, the present results indicate that it is not necessary in order to enhance long-term recognition memory via wakeful resting. The long-lived memory benefit gained via post-learning wakeful rest was shown to last at least 4 weeks in healthy adults, and free recall tests were more sensitive to the post-learning delay manipulation than cued recall tests. Finally, healthy controls and aMCI/mild AD patients who were able to learn face/name pairs showed enhanced 30-minute retention of these stimuli following wakeful rest conditions. The present findings demonstrate that both clinical and non-clinical populations are able to retain more new information over long periods, if the time interval immediately after new learning is devoid of further sensory stimulation. These results contribute to a growing body of literature stipulating that minimizing sensory stimulation frees early memory consolidation resources, allowing for superior offline consolidation of verbal material over a standard (≤1 hour) interval. The findings of this thesis extend this hypothesis over (i) a longer interval and (ii) to real-life-like stimuli, and these results are examined in light of memory consolidation theory. Implications of the premise of retroactive interference as a mechanism of longer-term forgetting are discussed.

Patients with temporal lobe epilepsy (TLE) often complain of a fading of new memories over days to weeks. This is particularly the case for patients with transient epileptic amnesia (TEA), a subtype of TLE. Objective memory testing sometimes corroborates this complaint, demonstrating normal or near-normal recall after standard delays (10-30 minutes), followed by a rapid decline in recall over longer delays (i.e. 1 week). This ‘nonstandard’ form of memory impairment has been termed accelerated long-term forgetting (ALF). It may reflect impairment of memory encoding, consolidation or retrieval. The aim of this thesis was to characterise the cognitive basis of ALF in TEA/TLE. The objectives were to: (a) determine the time scale of ALF of words (Chapter 3), (b) establish whether ALF affects picture recognition (Chapter 4), (c) establish whether ALF is affected by repeated retrieval (Chapter 2), number of learning trials (Chapter 5) and post-learning sensory stimulation (interference) (Chapter 5), (d) investigate ALF under incidental encoding conditions (Chapter 6), and (e) examine ALF associated with baclofen, a GABAB – receptor agonist (Chapter 7). A range of experimental paradigms and materials were applied to test memory function in several samples of TEA/TLE patients complaining of ALF and in healthy controls. The experiments revealed the following: ALF for word lists became apparent after 3–8 hours of daytime wakefulness, suggesting that disturbance of sleep related consolidation processes is not necessary for ALF to emerge in TEA. ALF for verbal information occurred both under incidental and intentional encoding conditions, and this rapid forgetting was not prevented by cued or recognition tests or by the matching of encoding conditions for patients and controls. This suggests that ALF is not associated primarily with an encoding or retrieval deficit. Although multiple learning trials and reduced sensory stimulation after learning reduced early forgetting (over 15-30 minutes) in TEA/TLE, neither factor reduced long-term forgetting. Moreover, in contrast to verbal recall, picture recognition was impoverished after minutes, but declined normally thereafter, demonstrating a subtle ‘early’ memory deficit in TEA, which might or might not be related to ALF. Overall, the present research suggests that ALF reflects a consolidation deficit, which results in accelerating forgetting the first few hours to days after memory acquisition, without a requirement for intervening sleep.

Long Term Evolution (LTE) is enormously adopted by several mobile operators and has been introduced as a solution to fulfil ever-growing Users (UEs) data requirements in cellular networks. Enlarged data demands engage resource blocks over prolong time interval thus results into more dynamic power consumption at downlink in Basestation. Therefore, realisation of UEs requests come at the cost of increased power consumption which directly affects operator operational expenditures. Moreover, it also contributes in increased CO2 emissions thus leading towards Global Warming. According to research, Global Information and Communication Technology (ICT) systems consume approximately 1200 to 1800 Terawatts per hour of electricity annually. Importantly mobile communication industry is accountable for more than one third of this power consumption in ICT due to increased data requirements, number of UEs and coverage area. Applying these values to global warming, telecommunication is responsible for 0.3 to 0.4 percent of worldwide CO2 emissions. Moreover, user data volume is expected to increase by a factor of 10 every five years which results in 16 to 20 percent increase in associated energy consumption which directly effects our environment by enlarged global warming. This research work focuses on the importance of energy saving in LTE and initially propose bandwidth expansion based energy saving scheme which combines two resource blocks together to form single super RB, thereby resulting in reduced Physical Downlink Control Channel Overhead (PDCCH). Thus, decreased PDCCH overhead helps in reduced dynamic power consumption up to 28 percent. Subsequently, novel reduced early handover (REHO) based idea is proposed and combined with bandwidth expansion to form enhanced energy ii saving scheme. System level simulations are performed to investigate the performance of REHO scheme; it was found that reduced early handover provided around 35% improved energy saving while compared to LTE standard in 3rd Generation Partnership Project (3GPP) based scenario. Since there is a direct relationship between energy consumption, CO2 emissions and vendors operational expenditure (OPEX); due to reduced power consumption and increased energy efficiency, REHO subsequently proven to be a step towards greener communication with lesser CO2 footprint and reduced operational expenditure values. The main idea of REHO lies in the fact that it initiate handovers earlier and turn off freed resource blocks as compare to LTE standard. Therefore, the time difference (Transmission Time Intervals) between REHO based early handover and LTE standard handover is a key component for energy saving achieved, which is estimated through axiom of Euclidean geometry. Moreover, overall system efficiency is investigated through the analysis of numerous performance related parameters in REHO and LTE standard. This led to a key finding being made to guide the vendors about the choice of energy saving in relation to radio link failure and other important parameters.

This doctoral thesis outlines several methodological advances in network science aimed towards uncovering rapid, complex interdependencies of electromagnetic brain activity recorded from the Electroencephalogram (EEG). This entails both new analyses and modelling of EEG brain network topologies and a novel approach to analyse rapid dynamics of connectivity. Importantly, we implement these advances to provide novel insights into pathological brain function in Alzheimer's disease. We introduce the concept of hierarchical complexity of network topology, providing both an index to measure it and a model to simulate it. We then show that the topology of functional connectivity estimated from EEG recordings is hierarchically complex, existing in a scale between random and star-like topologies, this is a paradigm shift from the established understanding that complexity arises between random and regular topologies. We go on to consider the density appropriate for binarisation of EEG functional connectivity, a methodological step recommended to produce compact and unbiased networks, in light of its new-found hierarchical complexity. Through simulations and real EEG data, we show the benefit of going beyond often recommended sparse representations to account for a broader range of hierarchy level interactions. After this, we turn our attention to assessing dynamic changes in connectivity. By constructing a unified framework for multivariate signals and graphs, inspired by network science and graph signal processing, we introduce graph-variate signal analysis which allows us to capture rapid fluctuations in connectivity robust to spurious short-term correlations. We define this for three pertinent brain connectivity estimates - Pearson's correlation coefficient, coherence and phase-lag index - and show its benefit over standard dynamic connectivity measures in a range of simulations and real data. Applying these novel methods to EEG datasets of the performance of visual short-term memory binding tasks by familial and sporadic Alzheimer's disease patients, we uncover disorganisation of the topological hierarchy of EEG brain function and abnormalities of transient phase-based activity which paves the way for new interpretations of the disease's affect on brain function. Hierarchical complexity and graph-variate dynamic connectivity are entirely new methods for analysing EEG brain networks. The former provides new interpretations of complexity in static connectivity patterns while the latter enables robust analysis of transient temporal connectivity patterns, both at the frontiers of analysis. Although designed with EEG functional connectivity in mind, we hope these techniques will be picked up in the broader field, having consequences for research into complex networks in general.

Care home admission following acute hospitalisation is a lived reality across Scotland, experienced by over 8,000 people annually. The aim of this thesis was to develop an understanding of new care home admission following acute hospitalisation. Methods and findings from the mixed-methods approach are presented in three parts. Part One: Identifying relevant research - includes a review of quality assessment tools for systematic reviewing; a systematic review and meta-analysis of quantitative data from observational studies of predictors of care home admission from hospital; and a methodological chapter on developing a search filter to improve accessibility of existing research findings supported by the findings of an international survey of care home researchers. The systematic review identified 53 relevant studies from 16 countries comprising a total population of 1,457,881 participants. Quantitative synthesis of the results from 11 of the studies found that increased age (OR 1.02 per year increase; 95%CI 1.00-1.04), female sex (OR 1.41; 95%CI 1.03-1.92), dementia & cognitive impairment (OR 2.14; 95%CI 1.24-3.70) and functional dependency (OR 2.06; 95%CI 1.58-2.69) were all associated with an increased risk of care home admission after hospitalisation. Despite international variation in service provision, only two studies described the model of care provided in the care home setting. The survey identified that there is a lack of shared terminology in the published literature to describe settings for adults who are unable to live independently in their own homes and require care in a long-term institutional setting. A search filter to identify relevant research could help to overcome differences in terminology and improve synthesis of existing research evidence. Part Two: Exploring current clinical practice - reports the findings of a retrospective cohort study of new care home admissions from hospital using case-note review methodology accompanied by findings from inductive thematic analysis of a single dataset from a qualitative case study design exploring the experiences of a patient, their family, and practitioners (n=5). The cohort study (n=100) found a heterogeneous picture with long hospital admissions (range 14-231 days), frequent transfers of care (31% experienced three or more transfers), varied levels of documented assessment and a lack of documented patient involvement in the decision-making processes. The qualitative interviews allowed the patient voice to emerge, alongside the professional and family narrative which dominated case-note documentation. Inductive thematic analysis identified nine major themes exploring how decisions are made to discharge individuals directly into a care home from the acute hospital setting: biography & personality; professional role; family role; limitations in local model of care; ownership of decision; risk; realising preferences; uncertainty of care home admission process; and psychological impact of in-hospital care. Part Three: Harnessing routinely-collected data - includes the challenges of identifying care home residency at admission and discharge from hospital, presenting analysis of the accuracy of Scottish Morbidity Record 1 (SMR01) coding in NHS Fife and the Community Health Index (CHI) Institution Flag in NHS Fife and NHS Tayside. This is followed by a descriptive analysis of the Scottish Care Home Census (2013-16) as a novel social care data source to explore care home admissions from hospital and the methodology for a data linkage study using these data. Identifying care home residents in routine data sources is challenging. In 18,720 admissions to NHS Fife, SMR01 coding had a sensitivity of 86.0% and positive predictive value of 85.8% in identifying care home residents on admission. At discharge the sensitivity was 87.0% and positive predictive value was 84.5%. From a sample of 10,000 records, the CHI Institution Flag had a sensitivity of 58.6% in NHS Fife and 89.3% in NHS Tayside, with positive predictive values of 99.7% and 97.7% respectively. From 2013-16, of 21,368 admissions to care homes in Scotland, 56.7% were admitted from hospital. There was significant regional variation in rates of care home admission from hospital (35.9-64.7%) and proportion of Local Authority funded places provided to admissions from hospital (34.4-73.9%). Those admitted from hospital appeared to be more dependent and sicker than those admitted from home. This thesis has established a series of challenges in how care homes and their residents are identified. It has questioned the adequacy of the evidence to guide practitioners and sought to raise the profile of this vulnerable and complex population and how best to support them in making decisions regarding admission from the acute hospital. It has progressed our understanding of this under-explored area and proposes a programme of future mixed-methods research involving patients, families, practitioners and policy-makers.

Over the last two decades, US corporate governance has witnessed a significant increase in the incidence and influence of shareholder activism. Shareholder activism, however, has been found to be inconsistent with US corporate governance which is framed within director primacy theory. In this theory, the board is able to carry out a unique combination of managerial and monitoring roles effectively, and shareholders are only capital providers to companies. Shareholder activism is normatively found inimical to effective and efficient decision-making, i.e. the board's authority, and to the long-term interests of public companies. The increasing willingness of institutional shareholders to participate into the decision-making processes of their portfolio companies is at odds with US corporate governance. Therefore, the aim of this thesis is to examine whether director primacy theory should be softened to accommodate greater shareholder activism in US corporate governance. This thesis presents an analysis of the legal rules that reflect director primacy theory. In this respect, US shareholders have traditionally had limited participatory power. The way in which the courts perceived the board's authority also stymied shareholder participation. This thesis considers not only legal and regulatory developments in the wake of the 2007-2008 financial crisis, but also the governance developments through by-law amendments which could potentially make an overall change in the balance of power between shareholders and the board. Shareholders are slowly moving to the centre of corporate governance in the US. History has shown that the board of directors often failed to prevent manager-induced corporate governance failures. This thesis argues that shareholder activism is necessary for improving the web of monitoring mechanisms and for a well-functioning director primacy model. Shareholder activism forces the board to more critical about management, which is a prerequisite for the director primacy model. Therefore, this thesis argues that shareholder activism should therefore be accommodated into US corporate governance. The proposed approach addresses accountability problems more effectively than the current director primacy model while recognising the board authority and enhances decision-making processes of public companies. In this regard, it makes several recommendations to soften the current director primacy model: establishing a level playing for private ordering, adopting the proxy access default regime, the majority voting rule, the universal proxy rules, and enhancing the disclosure requirements of shareholders. The present research also demonstrates that contemporary shareholder activism involves many complexities. It contains different types of shareholder activism, which differ by objectives, tools, and motives. It could be used for purely financial purposes or non-financial purposes or both. Furthermore, the concept of stewardship has been developed to address public interest concerns, namely short-termism in the market and pressures by activist funds through shareholder activism. In this way, this thesis develops a complete positive theory about shareholder activism rather than focussing on a specific type of activism. This complete analytical framework constitutes more reliable basis to draw normative conclusions rather than focussing on a particular type of activism.

One of the key requirements of fifth generation (5G) systems is having a connection to mobile networks without interruption at anytime and anywhere, which is also known as seamless connectivity. Nowadays, fourth generation (4G) systems, Long Term Evolution (LTE) and Long Term Evolution Advanced (LTE-A), are mature enough to provide connectivity to most terrestrial mobile users. However, for airborne mobile users, there is no connection that exists without interruption. According to the regulations, mobile connectivity for aircraft passengers can only be established when the altitude of the aircraft is above 3000 m. Along with demands to have mobile connectivity during a flight and the seamless connectivity requirement of 5G systems, there is a notable interest in providing in-flight wireless services during all phases of a flight. In this thesis, many issues related to the deployment and operation of the onboard systems have been investigated. A measurement and modelling procedure to investigate radio frequency (RF) propagation inside an aircraft is proposed in this thesis. Unlike in existing studies for in-cabin channel characterization, the proposed procedure takes into account the deployment of a multi-cell onboard system. The proposed model is verified through another set of measurements where reference signal received power (RSRP) levels inside the aircraft are measured. The results show that the proposed model closely matches the in-cabin RSRP measurements. Moreover, in order to enforce the distance between a user and an interfering resource, cell sectorization is employed in the multi-cell onboard system deployment. The proposed propagation model is used to find an optimum antenna orientation that minimizes the interference level among the neighbouring evolved nodeBs (eNBs). Once the optimum antenna deployment is obtained, comprehensive downlink performance evaluations of the multi-cell, multi-user onboard LTE-A system is carried out. Techniques that are proposed for LTE-A systems, namely enhanced inter-cell interference coordination (eICIC) and carrier aggregation (CA), are employed in the system analysis. Different numbers of eNBs, antenna mounting positions and scheduling policies are examined. A scheduling algorithm that provides a good tradeoff between fairness and system throughput is proposed. The results show that the downlink performance of the proposed onboard LTE-A system achieves not only 75% of the theoretical limits of the overall system throughput but also fair user data rate performance, irrespective of a passenger's seat location. In order to provide the seamless connectivity requirement of 5G systems, compatibility between the proposed onboard system deployment and the already deployed terrestrial networks is investigated. Simulation based analyses are carried out to investigate power leakage from the onboard systems while the aircraft is in the parked position on the apron. According to the regulations, the onboard system should not increase the noise level of the already deployed terrestrial system by 1 dB. Results show that the proposed onboard communication system can be operated while the aircraft is in the parked position on the apron without exceeding the 1 dB increase in the noise level of the already deployed terrestrial 4G network. Furthermore, handover parameters are obtained for different transmission power levels of both the terrestrial and onboard systems to make the transition from one system to another without interruption while a passenger boards or leaves the aircraft. Simulation and measurement based analyses show that when the RSRP level of the terrestrial system is below -65 dBm around the aircraft, a boarding passenger can be smoothly handed over to the onboard system and vice versa. Moreover, in order to trigger the handover process without interfering with the data transmission, a broadcast control channel (BCCH) power boosting feature is proposed for the in-cabin eNBs. Results show that employing the BCCH power boosting feature helps to trigger the handover process as soon as the passengers step on board the aircraft.

The selection of mortar for conservation of historic and heritage buildings can be challenging. Achieving compatibility with the historic fabric, durability and efficient use of materials within a practical timeframe often requires the use of hydraulic lime-based mortars which set more rapidly than the more traditional air lime mortars. These are considered to be more compatible with historic fabric than cement-based mortars, although, due to the modern production techniques and their natural variability, a deeper knowledge of their chemical and physical properties is needed to minimise damage due to incompatibility and make the decision process easier and safer. Natural hydraulic lime (NHL) binders are currently classified under EN 459-1:2015 in three designations, NHL 2, NHL 3.5 and NHL5, with the suffix representing the minimum compressive strength (in MPa) of a standard mortar mix at 28 days. The performance of NHL binders, manufactured by burning a naturally impure limestone, can be difficult to predict due to the inherent variability of both their physical and chemical characteristics. At the same time, the tolerance values for each classification allow for binders with significantly compressive strength differences to be classified by the same designation. The main aim of this research was to study a range of NHL binders, understand and quantify the variability of their characteristics and to establish how these properties influence the performance of mortars cured under standard and simulated weather conditions. In the first stage of the project, a selection of NHL binders from different origins and distinct designation were rigorously examined through physical, chemical and mineralogical characterisation to elucidate surface area, particle size distribution, oxide composition and crystalline phase composition. The characteristics of the binders were found to vary greatly, particularly amongst binders from the same classification and distinct origins, and in one particular case even from the same origin. A change of properties over time was also identified, binders manufactured in different years could have very different properties, even though, as far as could be ascertained from the packaging, it was the same product. Starting from a selection of 11 NHLs and 1 hydrated lime, the next step involved the manufacture of mortar samples using a sand aggregate appropriate for a conservation mortar with 1:2 ratio (binder:aggregate by volume). Sufficient water was added to produce a spread by flow table of 165 ± 10 mm. These mortars were cured under standard conditions and for a smaller group of binders under simulated weather conditions. For the standard cure conditions, the properties of the binders were compared to the physical properties in terms of strength (from 7 to 1080 days), porosity, capillary water absorption, water vapour permeability and freeze-thaw resistance of mortars made with the binders. The carbonation was also studied by phenolphthalein stain after all the flexural strength tests and after 2 years by XRD. The mortars under climate simulation were studied in terms of mechanical properties (up to 360 days) and carbonation. For comparison purposes, cement-lime (1:1:6 and 1:2:9 cement:lime:aggregate volumetric ratio), lime-metakaolin (MK) (with MK addition of 5, 10 and 20% of the lime mass) and lime putty mortars were manufactured to the same workability as the NHL mortars. These were studied in terms of strength up to 360 days, porosity and water absorption by capillarity action. The strength of the studied mortars does not follow the classification of the binders, with one binder, specified as NHL 2, resulting in a stronger mortar than another binder specified as NHL 5, and one NHL 3.5 mortar surpassing all the other mortars in terms of mechanical strength. The mechanical strength was found to correlate with the hydraulic phases, alite and belite, identified within the binders. The relative long-term performance of the mortars manufactured with the different binders can therefore be predicted based on the mineral properties rather than the standard classification. Pore related properties, such as water vapour permeability and water absorption by capillarity, were found to be related to the water/binder ratio of the NHL mortars. Later in the project, using the standard cured mortars data, a model was developed to predict compressive strength based on the proportion of crystalline phases present in the mortars, the surface area and the water/binder ratio. This model, applied to the studied mortars, was found to predict, with low error, the measured performance of the mortars, meaning that the model can be used as tool to predict mortar strength. The outcomes of this thesis demonstrated that with sufficient knowledge of the underlying chemistry of NHL binders, it is possible to establish the relative performance of mortars, thus making the decision on which binder to use easier and safer for the historic fabric.
