DIAZ-VILLAQUIRAN, Laura (Georgia State University). Exploring the Dietary Proclivities of Neanderthals Using Dental Microwear. Neanderthal fossil molars are found at several sites in Western Europe, including the caves of Hortus, Spy and La Quina. The remains from Hortus cave (n = 7) are particularly well represented archaeologically and all but one individual is associated with a specific phase of the deposit. In order to position unknown individual Hortus VI within a dietary context, microwear analysis was performed on epoxy resin molar casts from Hortus cave (n =7), La Quina (n =1), Spy cave (n =1), Hastire Caverne M and Hastire Trou Garon C (n=8). The data obtained from Hastire Caverne M and Hastire Trou Garon C, Homo sapiens, was included for comparative purposes and used to conduct a measurement error study in SPSS; which found no statistically significant error. Furthermore, the results of this study point towards age differentiation in the microwear signatures of Neanderthals, microwear signatures which may be reflective of age-related wear and paramasticatory cultural behavior or tool-like use of the dentition.

description: We give a simple and intuitive proof that the only states which are completely passive, i.e. those states from which work cannot be extracted even with infinitely many copies, are Gibbs states at positive temperatures. The proof makes use of the idea of virtual temperatures, i.e. the association of temperatures to pairs of energy levels (transitions). We show that (i) passive states are those where every transition is at a positive temperature, and (ii) completely passive states are those where every transition is at the same positive temperature.

title: The experiences of healthcare staff in using the Mental Capacity Act (2005) when working with people with a learning disability
Creators: name: McVey, Julie
Publisher: name: University of Liverpool Repository

description: The Mental Capacity Act (2005) (MCA) is part of the legislative framework of the NHS. Small scale studies in a range of health settings have shown that the understanding and use of the MCA (2005) varies considerably in different services and across staff of differing occupations and grades. The experiences of individual staff in using the MCA has received little attention. This grounded theory study aimed to explain how staff working with people with a learning disability (PWLD) make sense of and use the MCA, whilst also exploring the factors that influence applying the MCA in clinical practice. This study involved 11 healthcare staff from a specialist learning disability service that had used the MCA in the six months prior to their participation in the research. Staff interviews provided narratives about how they had used the MCA. A theoretical framework was developed from the analysis which underpinned three core conceptual categories. The first core category was that of ‘professional risk’ in which staff have awareness of a series of risks that pertain to themselves or the service user that could have negative professional or legal consequences. The second core category described ‘emotional risk’, which affected both the staff and service user. Staff appeared to experience those risks as feelings in the form of anxiety or concern. Both ‘professional risk’ and ‘emotional risk’ bring about ‘strategies’ which mediate the risk; allowing staff to justify and document their position, creating what feels like safe practice for both the staff and service user. Factors which facilitate the use of the Act are concerned not only with these risks but the significance of the decision that the service user has to make. The findings suggest that there is much uncertainty in the process of using the Act, some of which is due to the subjective nature of evidence gathering. The study suggests that peer support offers a range of factors important to education and development of experience in using the Act, along with helping staff cope with the outcome of decision making. The findings have clinical implications for those involved in managing difficult assessments and decision making, including how to gain an appropriate balance between risk and human rights against a backdrop of adversity that can be present for people with a learning disability. Further implications clinically and for future research, along with limitations of the study are also discussed.
Closeted Tiktok: Liminality, Internalized Stigma, and Heterotopia in the Rite of Coming Out

description:
The global shutdowns during the COVID-19 pandemic brough the social media app, TikTok, to the forefront of online communication and creativity. My own use of the app brought me to a series of videos that focus on LGBTQ+ experiences, issues, rights, and relationships. I was especially intrigued by a series of videos that discussed experiences with being in the closet and coming out, meaning to obscure or reveal ones sexual identity respectively. The focus of this ethnographic project is to understand how creating and engaging with these kinds of videos on TikTok impacts the coming out and closeted experience of men who love men with particular attention being paid to internalized sexual stigma. I argue that the coming out journey can be understood as a rite of passage and to be stuck in the closet is to be stuck in the liminal phase of that rite. I then argue that Closeted TikTok is a kind of heterotopia, created by the performative utterances of its users, that alleviates the experiences of internalized stigma which accompanies being stuck in this liminal stage. By simply speaking about their experiences, these accounts create a space for closeted men to feel like matter in place rather than matter out of place, a sentiment that is all too rare in their everyday lives.
title: Synthesis and molecular level characterisation of amorphous microporous networks
Creators: name: Laybourn, Andrea
Publisher: name: University of Liverpool Repository
Year: 2013

description: Conjugated microporous polymers (CMPs) are a class of materials that have advantageous properties, such as extended π-conjugation, tuneable micropore size and surface area, and the ability to swell. Owing to the limited solubility and the amorphous nature of CMPs, little information is known about their structure and characterisation is dominated by solid-state NMR spectroscopy. NMR is a technique which is sensitive to both molecular level structure and dynamics. An increase in understanding of these networks is required to give an overall picture of their physical properties and origins of flexibility, ultimately leading to the design of such materials for specific applications. In addition to the challenges with characterisation, a considerable disadvantage of CMPs is the cost of their synthesis. Many of the current routes to CMPs involve the use of heavy metal catalysts. Development of methodologies that use cheap monomers and do not require metal catalysts would increase the viability of CMPs for use in industrial applications. In this work advanced structural elucidation and investigations of network flexibility and porosity were achieved using two approaches. The first involves identification of a reaction mechanism for the formation of CMP-1 by examination of the products of reaction after incremental time periods. The second involves employing advanced solid-state NMR techniques, specifically deuterium NMR, to probe the molecular motions of deuterated versions of CMP-1 and CMP-2. Swelling experiments of CMP-1 and CMP-2 with benzene-d6 were also used to investigate changes in porosity for swollen and non-swollen networks. A new synthetic route to CMPs was also developed by exploiting the reaction between aldehydes and amines. In particular the formation of aminal linkages shall be explored, as this would allow preparation of branched networks from bi-functional monomers. Newly synthesised materials are to be fully characterised and their gas sorption properties will be analysed.
The Phoenix And The Sankofa Bird Atlantas Arts Institutions and Their Communities

description:
In the latter half of the 2010s gentrification and urban development contributed to the closure of many independent Atlanta art spaces and strained the resources of those that survived. In this environment, with fewer opportunities outside of academia and large institutions, local artists struggled to sustain their work and find community. However, recent increases in federal funding for public programming and arts that were part of the pandemic stimulus plan combined with a renewed interest in fostering the community resulted in a resurgence of public art and opportunities, both in Atlanta and nationwide.


This thesis reports my research on how art institutions are developing new structures to adapt, ensure longevity, and broaden their constituents. For centuries, museums and arts institutions functioned as exclusive spaces which only catered to the upper and upper-middle class. In 2022, inter-community networks, new organizations, programs, and spaces are questioning the status quo and creating new frameworks prioritizing sustainability and accessibility within the arts. Over a year and a half, I participated in public art projects and events, organized community art events, and interviewed creatives to understand the current state of Atlantas independent art community and its needs. Drawing on my findings, I show how this resurgence is impacting the local economy for artists, and how it can change the communitys future. Finally, I make a series of proposals, based on my research, for how arts institutions can support art communities in meaningful and supportive ways.
Human Femoral Head Dimorphism Compared to Sex Differences in the Diaphysis of the Femur
Creators: name: Thibault, Alyssa
Publisher: name: Georgia State University
Year: 2022

description:
The femur is the largest bone in the body, and it is one of the most common bones found at crime scenes and archaeological sites, which leads to the femoral head being used as a typical method of identifying the sex of individuals. In the GSU Bioarchaeology Teaching Laboratory, there are 20 femora; cause of death, age, and sex are unknown. This study focuses on measuring multiple femoral morphological structures, such as head, neck, lesser-greater trochanter, length, shaft, lateral-medial condyle, and intercondylar fossa. After collecting the measurements and morphology scores, SPSS is used to analyze the data. Prior to data collection, a measurement error study was conducted in which all of the measurements were collected on all individuals twice and these were compared using a t-test. The t-tests demonstrated that no significant difference existed between trials. The femoral head, which is utilized as a measure of sexual dimorphism, is highly and significantly correlated with neck height and trochanteric ridge. All three of these measurements are located proximally on the femur. A principal components analysis of all eight traits shows an imperfect separation of females and males, although a discriminant function analysis demonstrates no misclassification for sex attribution. A multiple linear regression with the head measurement as the dependent variable shows that femoral midshaft circumference has the highest beta weight, implying a unique relationship between sex membership and body mass. Overall, the results suggest that multiple traits are dimorphic in the femur, but those that are proximal show greater differentiation between the sexes.

description: A canonical basis in the sense of Lusztig is a basis of a free module over a ring of Laurent polynomials that is invariant under a certain semilinear involution and is obtained from a fixed "standard basis" through a triangular base change matrix with polynomial entries whose constant terms equal the identity matrix. Among the better known examples of canonical bases are the Kazhdan-Lusztig basis of Iwahori-Hecke algebras, Lusztig's canonical basis of quantum groups and the Howlett-Yin basis of induced $W$-graph modules. This paper has two major theoretical goals: First to show that having bases is superfluous in the sense that canonicalisation can be generalized to non-free modules. This construction is functorial in the appropriate sense. The second goal is to show that Howlett-Yin induction of $W$-graphs is well-behaved a functor between module categories of $W$-graph-algebras that satisfies various properties one hopes for when a functor is called "induction", for example transitivity and a Mackey theorem.

description: Quantum technologies are developing powerful tools to generate and manipulate coherent superpositions of different energy levels. Envisaging a new generation of energy-efficient quantum devices, here we explore how coherence can be manipulated without exchanging energy with the surrounding environment. We start from the task of converting a coherent superposition of energy eigenstates into another. We identify the optimal energy-preserving operations, both in the deterministic and in the probabilistic scenario. We then design a recursive protocol, wherein a branching sequence of energy-preserving filters increases the probability of success while reaching maximum fidelity at each iteration. Building on the recursive protocol, we construct efficient approximations of the optimal fidelity-probability trade-off, by taking coherent superpositions of the different branches generated by probabilistic filtering. The benefits of this construction are illustrated in applications to quantum metrology, quantum cloning, coherent state amplification, and ancilla-driven computation. Finally, we extend our results to transitions where the input state is generally mixed and we apply our findings to the task of purifying quantum coherence.

description: The statistics of local measurements performed on certain entangled states can be reproduced using a local hidden variable (LHV) model. While all known models make use of an infinite amount of shared randomness---the physical relevance of which is questionable---we show that essentially all entangled states admitting a LHV model can be simulated with finite shared randomness. Our most economical model simulates noisy two-qubit Werner states using only 3.58 bits of shared randomness. We also discuss the case of POVMs, and the simulation of nonlocal states with finite shared randomness and finite communication. Our work represents a first step towards quantifying the cost of LHV models for entangled quantum states.

description: We introduce partial secondary invariants associated to complete Riemannian metrics which have uniformly positive scalar curvature outside a prescribed subset on a spin manifold. These can be used to distinguish such Riemannian metrics up to concordance relative to the prescribed subset. We exhibit a general external product formula for partial secondary invariants, from which we deduce product formulas for the higher rho-invariant of a metric with uniformly positive scalar curvature as well as for the higher relative index of two metrics with uniformly positive scalar curvature. Our methods yield a new conceptual proof of the secondary partitioned manifold index theorem and a refined version of the delocalized APS-index theorem of Piazza-Schick for the spinor Dirac operator in all dimensions. We establish a partitioned manifold index theorem for the higher relative index. We also show that secondary invariants are stable with respect to direct products with aspherical manifolds that have fundamental groups of finite asymptotic dimension. Moreover, we construct examples of complete metrics with uniformly positive scalar curvature on non-compact spin manifolds which can be distinguished up to concordance relative to subsets which are coarsely negligible in a certain sense. A technical novelty in this paper is that we use Yu's localization algebras in combination with the description of K-theory for graded C*-algebras due to Trout. This formalism allows direct definitions of all the invariants we consider in terms of the functional calculus of the Dirac operator and enables us to give concise proofs of the product formulas.

description: We study symplectic invariants of the open symplectic manifolds $X_Γ$ obtained by plumbing cotangent bundles of 2-spheres according to a plumbing tree $Γ$. For any tree $Γ$, we calculate (DG-)algebra models of the Fukaya category $\mathcal{F}(X_Γ)$ of closed exact Lagrangians in $X_Γ$ and the wrapped Fukaya category $\mathcal{W}(X_Γ)$. When $Γ$ is a Dynkin tree of type $A_n$ or $D_n$ (and conjecturally also for $E_6,E_7,E_8$), we prove that these models for the Fukaya category $\mathcal{F}(X_Γ)$ and $\mathcal{W}(X_Γ)$ are related by (derived) Koszul duality. As an application, we give explicit computations of symplectic cohomology of $X_Γ$ for $Γ=A_n,D_n$, based on the Legendrian surgery formula of Bourgeois, Ekholm and Eliashberg.

description: We present explicit formulas for the Macdonald polynomials of types $C_n$ and $D_n$ in the one-row case. In view of the combinatorial structure, we call them "tableau formulas". For the construction of the tableau formulas, we apply some transformation formulas for the basic hypergeometric series involving very well-poised balanced ${}_{12}W_{11}$ series. We remark that the correlation functions of the deformed $\mathcal{W}$ algebra generators automatically give rise to the tableau formulas when we principally specialize the coordinate variables.
The drop in female homicide victimisation in Australia
Creators: name: Forrest, Walter
Publisher: name: University of Limerick
Year: 2023
Subjects: Law and legal studies

description: Despite widespread community concern about the incidence of lethal violence against women in Australia, the numbers and rates of women murdered each year have been falling for almost 30 years. The risk of homicide victimisation among Australian women is now the lowest it has ever been since federation. Few studies have explored these patterns or sought to explain their development. One plausible explanation, anticipated by feminist theories of violence, is that homicide has declined as the status of women and gender equality have increased. In this paper, I analyse changes in the annual female homicide victimisation rate in Australia from 1962 to 2016. Using unobserved components models, I investigate the extent to which increases in either the status of women or gender equality can account for the decline in female homicide victimisation since the late 1980s. Despite absolute and relative advances in women’s educational access and achievement, labour force participation, and earnings, those changes had little discernible impact on the aggregate-level risk of lethal violence against women. Instead, other social and economic conditions, such as falling unemployment, the shrinking of the young male population and ongoing urbanisation, seem better able to explain recent improvements in women’s safety.
title: Monolayer and multilayer & mixed OH/water on Pd(111)
Creators: name: Cummings, Linda
Publisher: name: University of Liverpool Repository
Year: 2525

description: An extensive amount of literature can be found containing experimental and theoretical studies of water adsorption on metal surfaces, yet an understanding of the water – metal interface remains far from complete. The binding energy of the water – metal interface determines whether water wets a metal surface to form a complete hydrogen bonded network, forms 3-dimensional ice clusters on a non-wetting surface or dissociates to form hydroxyl, hydrogen and sometimes oxygen on the surface. All of these structures are seen depending on the growth conditions and reactivity of the metal surface. In this thesis it is shown that submonolayer water adsorbs intact on Pd(111) to form a structure with (√3×√3)R30° periodicity. As the first layer saturates the spots in the √3 position split due to the formation of dense domain boundaries. Although the first layer of water covers the Pd surface, subsequent layer-by-layer growth does not occur. Instead, an extended superstructure forms by attaching 3D clusters of ice and areas of bare monolayer remain exposed. The formation of an ordered oxygen network results in detection of an intense LEED pattern, even at a coverage of 80 layers. As the first layer of water compresses, it stabilises the growth of the larger superstructure. Further investigation shows the hydrogen network formed during multilayer growth is weakly bonded and helium atom scattering shows that there is disorder on a local scale. Co-adsorption of oxygen alters the structure and stability of water overlayers and on Pd(111) a stable mixed (OH + H2O) layer forms with (√3×√3)R30° periodicity but is unreactive towards hydrogen, therefore the low temperature reaction between hydrogen and oxygen cannot be catalysed.

description: Motivation: The high dimensionality of genomic data calls for the development of specific classification methodologies, especially to prevent over-optimistic predictions. This challenge can be tackled by compression and variable selection, which combined constitute a powerful framework for classification, as well as data visualization and interpretation. However, current proposed combinations lead to instable and non convergent methods due to inappropriate computational frameworks. We hereby propose a stable and convergent approach for classification in high dimensional based on sparse Partial Least Squares (sparse PLS). Results: We start by proposing a new solution for the sparse PLS problem that is based on proximal operators for the case of univariate responses. Then we develop an adaptive version of the sparse PLS for classification, which combines iterative optimization of logistic regression and sparse PLS to ensure convergence and stability. Our results are confirmed on synthetic and experimental data. In particular we show how crucial convergence and stability can be when cross-validation is involved for calibration purposes. Using gene expression data we explore the prediction of breast cancer relapse. We also propose a multicategorial version of our method on the prediction of cell-types based on single-cell expression data. Availability: Our approach is implemented in the plsgenomics R-package.

Creators: name: Shahani, Sahib

Year: 2014

description: The extensive assessment of bull’s reproductive potential prior to breeding is highly important and includes examination of general physical soundness, external and internal genitalia and semen quality. Breeding success depends on the efficient use of bulls with high breeding value but simultaneously semen quality imposes restrictions on the use of these bulls in AI. Several techniques have been devised to assess quality of either fresh or frozen-thawed semen. Among a variety of traditional parameters sperm concentration, sperm raw and post-thaw motility and sperm morphology are commonly used for routine semen assessment in the laboratory. In this study, we investigated differences in sperm metabolic activity relative to their motility that may reflect better the fertility of bulls from their non-return rates (NRRs). To investigate the relationship between mid-piece length and fertility of bovine spermatozoa, sperm biometry was performed on ejaculates obtained from 34 bulls representing six breeds: Holstein (yearlings and mature), Friesian, Belgian Blue, Aberdeen Angus, Charolais and Limousin.

title: Mechanisms and contexts of kin recognition in female house mice
Creators: name: Holmes, Andrew
Publisher: name: University of Liverpool Repository
Year: 2014

description: As relatives share genes that are identical by descent, organisms can gain additional fitness benefits by improving the reproductive success of known kin. There are a number of costs associated with close inbreeding, including an increased likelihood of the expression of recessive deleterious alleles and reduced survivorship. The ability to recognise kin therefore enables individuals to improve their inclusive fitness and avoid problems associated with close inbreeding. Female house mice (Mus musculus domesticus) will nest and nurse offspring communally. Choosing an appropriate nest partner is therefore important and competition between nesting females can result in reproductive inhibition and infanticide. Kin selection theory suggests that females could gain inclusive fitness benefits from nesting with relatives. This thesis explores the mechanisms of kin recognition in female house mice in the contexts of social partner choice and inbreeding avoidance. Female house mice recognised unfamiliar relatives, suggesting a phenotype matching mechanism for kin recognition. Females were presented with maternal and paternal half-siblings to investigate recognition template formation. Females nested with maternal but not paternal half-sisters, suggesting that female house mice may use a recognition template learnt from their mother for social partner choice decisions. However females avoided both maternal and paternal half-brothers suggesting that females may use a match-to-self mechanism for inbreeding avoidance. Female house mice were able to identify relatives from urine, suggesting that genetic markers are present in urine. To investigate the molecular markers of kin recognition mice were bred to control for the major histocompatibility complex (MHC) and major urinary proteins (MUPs). Females nested with females that matched for MHC or MUP type, suggesting that both gene families may be used for kin recognition between females. A non-significant trend was observed for females to avoid males that matched themselves for MUP type, but females showed no avoidance of males that matched for MHC type. A small pilot experiment investigated the physiological effects of female social environment. Housing with unfamiliar females resulted in short-term decreases in female body mass and urinary protein concentration but an increase in urinary creatinine concentration. Competition between unfamiliar females may have resulted in a decreased water uptake and an increase in scent marking which could explain the physiological changes observed. Together these results suggest that female house mice may use two mechanisms of kin recognition. For social partner choice females may use a match-to-maternal MHC and MUP type mechanism, whilst for inbreeding avoidance females may use a match-to-own MUP type mechanism. The possibility of a single species using two separate mechanisms suggests that kin recognition may be considerably more complex than previously thought.

description: We prove that every Q-factorial complete toric variety is a finite quotient of a poly weighted space (PWS), as defined in our previous work arXiv:1501.05244. This generalizes the Batyrev-Cox and Conrads description of a Q-factorial complete toric variety of Picard number 1, as a finite quotient of a weighted projective space (WPS) \cite[Lemma~2.11]{BC} and \cite[Prop.~4.7]{Conrads}, to every possible Picard number, by replacing the covering WPS with a PWS. As a consequence we describe the bases of the subgroup of Cartier divisors inside the free group of Weil divisors and the bases of the Picard subgroup inside the class group, respectively, generalizing to every Q-factorial complete toric variety the description given in arXiv:1501.05244, Thm. 2.9, for a PWS.

description: BACKGROUND Cerebral malaria is a major cause of mortality and morbidity in African children. Pathology is related to interactions between malaria-infected red blood cells (iRBC) and the endothelium but the aetiology of the neurological compromise remains unclear. METHODS This thesis involved direct and downstream investigation of the endothelium in Malawian children with cerebral malaria and controls in post-mortem samples, plasma and through developing a novel ex vivo method to examine endothelium in subcutaneous tissue. RESULTS In post-mortem samples of brain in fatal cerebral malaria, there was thrombosis and loss of endothelial protein C receptor (EPCR) associated with iRBC sequestration. iRBC associated loss of EPCR and thrombomodulin was also demonstrated in post- mortem samples of gut and subcutaneous tissue but this was less marked than in the brain and rarely associated with thrombosis. Subcutaneous biopsies taken on admission with cerebral malaria demonstrated reduced EPCR and thrombomodulin ex vivo, showing that loss of these receptors is present at the time of presentation and are not just agonal events. Examination of coagulation in blood demonstrated activation of coagulation, as indicated by raised thrombin-anti-thrombin complexes and reduced protein C and antithrombin levels. However this was compensated as there was normal prothrombin fragment (F1+2)-to-activated protein C ratios and only mildly altered clotting times. Examination of markers of endothelial activation (soluble Intracellular Adhesion 2 Molecule-1 [sICAM-1] and Angiopoetin-2 [Ang-2]) and inflammation (C-reactive protein [CRP]) revealed endothelial activation and inflammation at presentation and during recovery and demonstrated that in cerebral malaria and in uncomplicated malaria there is persistent endothelial activation after parasites are cleared, up to a month after presentation. Complexes of very low density lipoprotein (VLDL) and CRP were also raised in cerebral and uncomplicated malaria. CONCLUSIONS In cerebral malaria in Malawian children there is localised microvascular loss of endothelial anticoagulant receptors at sites of iRBC sequestration. In the brain, where constitutive expression of EPCR and thrombomodulin is low, this is accompanied by thrombosis; outside the brain, where constitutive EPCR and thrombomodulin expression is high, coagulation is compensated. This activation of coagulation and of the endothelium in response to acute infection leaves a residual imprint as detected by markers of endothelial activation and inflammation even in uncomplicated malaria several weeks after parasites are cleared. Since children in sub-Saharan African frequently suffer repeated infections these endothelial alterations may have important consequences both for subsequent infections and for long-term health. These mechanisms highlight potential targets for therapy.
title: Investigating the drivers of spatial and temporal biodiversity patterns of the Machair

description: In plant ecology, understanding which species live where and why is fundamental for ensuring successful conservation management with the aim of maintaining biodiversity and ecosystem services. Biodiversity patterns in space can be empirically linked to spatially scaled environmental processes, providing a greater understanding to how plant species assemblages change along differing environmental gradients. In the same way, biodiversity patterns in time can be linked to temporal trends in the environment, empirically linking changes in vegetation to changes in the external environment. This furthers understanding of how plant communities are likely to respond to future scenarios of environmental change, providing an insight into future shifts in biodiversity patterns and, in turn, how his may influence valuable ecosystem functions and services upon which humans ultimately depend. Trends in human land use have been shown to be the single most influential driver of current global biodiversity change to date. This, coupled with a changing climate, suggests vegetation communities on a global scale are under increasing pressure to adapt to multiple dynamically changing environmental constraints. This thesis focuses on a globally-rare semi-natural, coastal grassland habitat termed ‘Machair’, renowned for its high biodiversity and cultural heritage importance. Confined solely to the north-western fringe of Europe, the Machairs have formed through unique combinations of geo-physiological and climatic conditions, and even more importantly, century-long associations with human land use through which the low-intensity intermediate disturbance is considered to be vital in maintaining its biodiversity value. However, change in the management of the Machairs alongside other environmental drivers of change, particularly climate, provides major concerns for the biodiversity value of this habitat. In this thesis, spatial and temporal biodiversity patterns of Machair vegetation are investigated to assess the major drivers of change and identify regions which may require future conservation efforts to restore and/or maintain the future biodiversity value of this globally-rare habitat. To achieve this, a spatio-temporal dataset of Scottish Machair vegetation first collected in 1976-77 and then re-surveyed in 2009-10 was used. Analyses found both climate and land use management to influence spatial and temporal vegetation patterns of Scotland’s Machair and Machair grassland. Climate was shown to operate at relatively broad scales (>50km), while the influence of different measurable components of climate was also found to significantly affect temporal turnover patterns of Machair grassland assemblages. Land use management, predominantly at a relatively fine scale (

description: For the Warm Dark Matter (WDM) candidates the momentum distribution of particles becomes important, since it can be probed with observations of Lyman-$α$ forest structures and confronted with coarse grained phase space density in galaxy clusters. We recall the calculation bt Kaplinghat (2005) of the spectrum in case of dark matter non-thermal production in decays of heavy particles emphasizing on the inherent applicability conditions, which are rather restrictive and sometimes ignored in literature. Cold part of the spectrum requires special care when WDM is considered.

description: The wireless computer networks have an uncertainty in their structures aside from their big advantages for the users. The environmental conditions, changing locations of the mobile hosts and the changing components in the system can easily affect their reliability. In order to know a system capability performing its functions, keep the reliability at a certain level and/or detect the deficiency of the system, it is necessary to analyze the reliability of a computer communication network including the wired and wireless parts. But the above reasons also make the analysis and a unique solution difficult so a set of algorithms is proposed to analyze it. In this thesis, two-terminal reliability is mainly dealt with.

The changing locations of the mobile nodes are considered the main problem to obstruct analyzing the reliability. In the range of an access point (base station), a mean value can be accepted for its success probability. Therefore the mobility models of the mobile nodes are considered for the solution and the Markov chains are tried to predict the next locations. In order to provide a connection and make an analysis, the initial positions of the source and destination are assumed to be known.

There are four conditions in the computer network according to the starting and finishing positions. They are static to static, mobile to static, static to mobile and mobile to mobile conditions. The algorithm for static to static conditions is proposed only for the definite situations in which the hierarchical addressing is used. Three of them related to the mobile nodes give different results in a time interval. The least one of them is considered as minimum two-terminal reliability and the biggest one is considered as maximum two-terminal reliability. Also some flexible solutions are proposed for the different applications of the computer network.

A simulation is performed with the appropriate movement routes of the mobile nodes according to the mobility model and then the proposed algorithms are tried. It is seen that the simulation results are correspondent with the algorithms results.
