description: A cryogen-free cryostat cooled by a closed cycle cryocooler is compact, can provide uninterrupted long-term operation (up to ten thousand hours) and is suited to temperatures from 3 K to 300 K. Its intrinsic temperature oscillation, however, limits its application in experiments requiring high thermal stability at low temperature (below 77 K). Passive suppression methods are effective but all suffer from drawbacks. We describe a novel, active suppression scheme more efficient than traditional proportional-integral (PI) control. The experimental results show that it can reduce the standard deviation of the temperature oscillation by a further 30% compared with PI feedback. To the best of our knowledge, this is the first time such active suppression of temperature oscillations has been implemented with the cryogen-free cryostat. The results also show, however, that an unwanted lower frequency thermal noise will be generated, which appears to be the limit of the method. Nevertheless, the approach could be used to improve the temperature stability in all cryogen-free cryostats.

description: (Abridged) We present the results of photometric measurements from images of the LMC globular clusters NGC 1928, 1939 and Reticulum taken with ACS on HST. F555W and F814W exposures result in high accuracy CMDs for these three clusters. This is the first time that CMDs for NGC 1928 and 1939 have been published. All three clusters possess CMDs with features indicating them to be >10 Gyr old, including main sequence turn-offs at V~23 and well populated HBs. We use the CMDs to obtain metallicity and reddening estimates for each cluster. NGC 1939 is a metal poor cluster, with [Fe/H] = -2.10 +/- 0.19, while NGC 1928 is significantly more metal rich, with [Fe/H] = -1.27 +/- 0.14. Reticulum's abundance lies between the two, at [Fe/H] = -1.66 +/- 0.12. All three clusters are moderately reddened with values ranging from E(V-I) = 0.07 +/- 0.02 for Reticulum and E(V-I) = 0.08 +/- 0.02 for NGC 1928, to E(V-I) = 0.16 +/- 0.03 for NGC 1939. We estimate the HB morphology of each cluster. NGC 1928 and 1939 possess HBs consisting almost exclusively of stars to the blue of the instability strip. In contrast, Reticulum has an intermediate HB morphology, with stars across the instability strip. Using a variety of dating techniques we show that these three clusters are coeval with each other and the oldest Galactic and LMC globular clusters, to within ~2 Gyr. The census of known old LMC globular clusters therefore now numbers 15 plus the unique, somewhat younger cluster ESO121-SC03. The NGC 1939 field contains another cluster in the line-of-sight, NGC 1938. A CMD for this object shows it to be less than ~400 Myr old, and it is therefore unlikely to be physically associated with NGC 1939.

description: Sidney Charles McLennan was my grandfather. He was born on 24/10/1896 at Banchory Ternan, Kincardineshire, Scotland, the son of William McLennan and Mary Black McLennan née McGillivray. They lived at Rosebank Cottage, Banchory Ternan. He served in the 4th Seaforth Highlanders with service number 3239 and in the Tank Corps with service number 91625. He went to France on 21/08/1915. He was discharged on 20/03/1919.His brothers James Alexander, William and Douglas George served in the war. William died but the others survived. I have photographs of the various brothers taken between 1914 and 1916. I have one of Sidney Charles McLennan in uniform wearing a kilt. Another image has two photographs: Sidney Charles McLennan is on the right wearing trews and his young brother Bert (Robert Milne McLennan) is on the left. I have a photograph of a bayonet fighting class with the Seaforth and Cameron Brigade; Sidney Charles McLennan is on the 2nd row, 7th from right. I have another photograph of him at a convalescence hospital in 1916 after injuring his right hand. It is unknown where the hospital was.

description: Collimated relativistic outflows, or jets, are amongst the most energetic and relativistic phenomena in the Universe. They are associated with supermassive black holes in distant active galactic nuclei (AGN), accreting black holes and neutron stars in binary systems and are believed to be responsible for gamma-ray bursts. The physics of these jets,however, remains something of a mystery in that their bulk velocities, compositions and energetics remain poorly determined. Here we report the discovery of an ultra-relativistic outflow from a binary accreting neutron star accreting gas within a binary system. The velocity of the outflow is comparable to the fastest-moving flows observed from active galactic nuclei, and its strength is modulated by the rate of accretion of material onto the neutron star. Shocks are energized further downstream in the flow, which are themselves moving with mildly relativistic bulk velocities and are the sites of the observed synchrotron emission from the jet. We conclude that the generation of such highly relativistic outflows does not require properties unique to black holes, such as an event horizon.

description: We demonstrate that there exist stationary states of Bose-Einstein condensates in an optical lattice that do not satisfy the usual Bloch periodicity condition. Using the discrete model appropriate to the tight-binding limit we determine energy bands for period-doubled states in a one-dimensional lattice. In a complementary approach we calculate the band structure from the Gross-Pitaevskii equation, considering both states of the usual Bloch form and states which have the Bloch form for a period equal to twice that of the optical lattice. We show that the onset of dynamical instability of states of the usual Bloch form coincides with the occurrence of period-doubled states with the same energy. The period-doubled states are shown to be related to periodic trains of solitons.

title: Promoting social norms via microeconomics teaching
Creators: name: Buchter, Kamilla Haworth
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: In this thesis I argue that one way scientific descriptions can become self-fulfilling is by promoting social norms among the people they are disseminated to. Identifying this mechanism will enable us to change unwanted social implications caused by it. To make the argument, I rely on the definition of social norms given by Bicchieri [2006] in The Grammar of Society and use the case of microeconomics as it is presented in university textbooks. Thus, the aim of the thesis is to argue that one way microeconomics can be self-fulfilling is by promoting a social norm of self-interest - and often narrow self-interest - via its textbooks and university teaching practices. To do this, I first use the current empirical findings to argue that the dissemination of the rationality assumption as it is presented in microeconomics textbooks can make microeconomics self-fulfilling. Second, I conduct a historical analysis to show that the claims that greed and self-interest are beneficial have been a part of modern economics from its beginning and still is today. I then discuss why the rationality assumption is a part of contemporary microeconomics and analyse how it is presented in standard textbook models today. Here, we see that even though some of the models can account for other-regarding preferences, the textbooks do not mention this fact. Instead, they present the rationality assumption as focusing on self-interested preferences only, and justify it as being both descriptively plausible and normatively desirable. Finally, I use the above analyses to argue that microeconomics textbooks and teaching practices can change people’s behaviour by making them follow a social norm of self-interest in economic situations. I end the thesis by presenting the results of an empirical study designed to test this argument.
Parameter Estimation for Tests of General Relativity with the Astrophysical Stochastic Gravitational Wave Background

description: Recent observations of gravitational waves from binary black holes and neutron stars allow us to probe the strong and dynamical field regime of gravity. On the other hand, a collective signal from many individual, unresolved sources results in what is known as a stochastic background. We here consider probing gravity with such a background from stellar-mass binary black hole mergers. We adopt a simple power-law spectrum and carry out a parameter estimation study with a network of current and future ground-based detectors by including both general relativistic and beyond general relativistic variables. For a network of second-generation detectors, we find that one can place meaningful bounds on the deviation parameter in the gravitational-wave amplitude if it enters at a sufficiently negative post-Newtonian order. However, such future bounds from a stochastic background are weaker than existing bounds from individual sources, such as GW150914 and GW151226. We also find that systematic errors due to mismodeling of the spectrum is much smaller than statistical errors, which justifies our use of the power-law model. Regarding a network of third-generation detectors, we find that the bounds on the deviation parameter from statistical errors improve upon the second-generation case, though systematic errors now dominate the error budget and thus one needs to use a more realistic spectrum model. We conclude that individual sources seem to be more powerful in probing general relativity than the astrophysical stochastic background.

description: We study previously unconsidered 3-3-1 models which are characterized by each lepton generation having a different representation under the gauge group. Flavor-changing neutral currents in the lepton sector occur in these models. To satisfy constraints on mu to 3e decays, the Z' must be heavier than 2 to 40 TeV, depending on the model and assignments of the leptons. These models can result in very unusual Higgs decay modes. In most cases the mu-tau decay state is large (in one case, it is the dominant mode), and in one case, the Higgs to s-sbar rate dominates.

description: The story is about the Williams family from Kemnay, Aberdeenshire, and is given in an article extracted from a Newspaper Archive. There are nine photographs accompanying the article, which is entitled 'KEMNAY PARENTS AND THEIR PATRIOTIC SONS'. Top left and top right are Mr and Mrs Williams, Viewforth, Kemnay. They are my great grandparents. The text of the article reads: 'Above are photos of Mr and Mrs Williams, Viewforth, Kemnay, with their six soldier sons and one grandson. Four of the sons are with the colours; two are privates in the Army B Reserve. The grandson, Private William Dow, 6th Gordons, has fallen in the fight. He died of wounds received at Neuve Chapelle. Mr Williams is foreman wayman on the Kemnay section of the G.N.S.R. Mr and Mrs Williams are highly respected in the Kemnay district, and both are to be congratulated on the patriotism shown by their family. Their record is certainly a highly creditable one'.My great grandparents' forenames were James and Jessie. James Williams and Jessie Ross were married in 1879. The 1891 census shows them living at Littlemill Cottage, Leslie, Aberdeenshire. Four of their sons are living with them: James aged 11, Adam B aged 8, William B aged 6 and George S aged under 1. There are also three daughters. At the time of the 1901 census they were at Udny, Aberdeenshire, and their John aged 8 was there along with Adam and George. Alexander was born to Jessie before she married James Williams.The full name of William Dow, who is listed in the newspaper article as grandson of Mr and Mrs Williams, was William Beattie Dow. He was the son of Alexander Dow and Helen Dow née Laing. He was the stepson of Mary Stuart Dow of Daisy Cottage, Bankhead, Aberdeenshire. Alexander and Helen were married on 14 January 1895 at Tarves. Alexander Dow married Marjory Stuart Williams in 1901 at Newhills. She was the daughter of Jessie Ross, born before she married James Williams. Alexander died in 1913.William Beatie Dow died of wounds on 14/03/1915, aged 19. He is buried at Merville Communal Cemetery, Nord, France. The grave reference is Plot II, Row E, Grave 08.

description: Capsule Networks (CapsNets) have been proposed as an alternative to Convolutional Neural Networks (CNNs). This paper showcases how CapsNets are more capable than CNNs for autonomous agent exploration of realistic scenarios. In real world navigation, rewards external to agents may be rare. In turn, reinforcement learning algorithms can struggle to form meaningful policy functions. This paper's approach Capsules Exploration Module (Caps-EM) pairs a CapsNets architecture with an Advantage Actor Critic algorithm. Other approaches for navigating sparse environments require intrinsic reward generators, such as the Intrinsic Curiosity Module (ICM) and Augmented Curiosity Modules (ACM). Caps-EM uses a more compact architecture without need for intrinsic rewards. Tested using ViZDoom, the Caps-EM uses 44% and 83% fewer trainable network parameters than the ICM and Depth-Augmented Curiosity Module (D-ACM), respectively, for 1141% and 437% average time improvement over the ICM and D-ACM, respectively, for converging to a policy function across "My Way Home" scenarios.

description: Single-walled carbon nanotubes (SWCNTs) in their pristine form have high thermal conductivity whose further improvement has attracted a lot of interest. Some theoretical studies have suggested that the thermal conductivity of a $(10,10)$ SWCNT is dramatically enhanced by C$_{60}$ fullerene encapsulation. However, recent experiments on SWCNT bundles show that fullerene encapsulation leads to a reduction rather than an increase in thermal conductivity. Here, we employ three different molecular dynamics methods to study the influence of C$_{60}$ encapsulation on heat transport in a $(10,10)$ SWCNT. All the three methods consistently predict a reduction of the thermal conductivity of $(10,10)$ SWCNT upon C$_{60}$ encapsulation by $20\%-30\%$, in agreement with experimental results on bundles of SWCNTs. We demonstrate that there is a simulation artifact in the Green-Kubo method which gives anomalously large thermal conductivity from artificial convection. Our results show that the C$_{60}$ molecules conduct little heat compared to the outer SWCNT and reduce the phonon mean free paths of the SWCNT by inducing extra phonon scattering. We also find that the thermal conductivity of a $(10,10)$ SWCNT monotonically decreases with increasing filling ratio of C$_{60}$ molecules.

description: Theoretically, CME kinematics are related to magnetic reconnection processes in the solar corona. However, the current quantitative understanding of this relationship is based on the analysis of only a handful of events. Here we report a statistical study of 60 CME-flare events from August 2010 to December 2013. We investigate kinematic properties of CMEs and magnetic reconnection in the low corona during the early phase of the eruptions, by combining limb observations from STEREO with simultaneous on-disk views from SDO. For a subset of 42 events with reconnection rate evaluated by the magnetic fluxes swept by the flare ribbons on the solar disk observed from SDO, we find a strong correlation between the peak CME acceleration and the peak reconnection rate. Also, the maximum velocities of relatively fast CMEs (> 600 km/s) are positively correlated with the reconnection flux, but no such correlation is found for slow CMEs. A time-lagged correlation analysis suggests that the distribution of the time lag of CME acceleration relative to reconnection rate exhibits three peaks, approximately 10 minutes apart, and on average, acceleration-lead events have smaller reconnection rates. We further compare the CME total mechanical energy with the estimated energy in the current sheet. The comparison suggests that, for small-flare events, reconnection in the current sheet alone is insufficient to fuel CMEs. Results from this study suggest that flare reconnection may dominate the acceleration of fast CMEs, but for events of slow CMEs and weak reconnection, other mechanisms may be more important.

title: A Home of Their Own: A Case Study of an Ethnically Diverse Community and Placement of People Seeking Asylum
Creators: name: Richards, Louise M. M.
Publisher: name: The Open University
Year: 2009

description: My thesis on asylum dispersal is written within an emotionally charged atmosphere concerning immigration, asylum, multiculturalism and Islamic extremism. In this climate of unreasoned attitudes towards asylum seeking generally, my main aim was to qualitatively investigate, via one case study area - Romantown - the persistent policy and political problem of where to place asylum seekers.

The suitability of Romantown, as a dispersal area, has ultimately concurred with polls that suggested dispersal to ethnically diverse areas created less public anxiety and reduced the possibility of violence and unrest (Flynn, 2003). As a dispersal site, Romantown also reflects the recommendations on suitability made by the Audit Commission regarding ethnic composition, the existence of refugee networks and existing places of worship for new asylum populations (Robinson et al, 2003, Audit Commission, 2000c). So the research questions I have focussed on are: 1. Do ethnically diverse communities like Romantown make better dispersal sites for asylum seekers? 2. What are the particular social and cultural dynamics that exist within this community in relation to asylum seeker dispersal? 3. How and in what ways have the range of agencies (statutory, voluntary, faith/refugee based) in Romantown engaged in the governance of multiculture and asylum seeker integration?

The fieldwork findings from the case study however revealed a more complex picture. Firstly there were elements of hospitality and tension between community residents and asylum seekers, and secondly whilst community agency management was very extensive with a number of committed individuals, overall it was chaotic and generally badly funded. Key findings from Chapters Five and Six presented unexpected cultural divisions between Sikh and Pakistani residents and Kurdish asylum seekers although ultimately dialogue was managed through competent agency and faith community intervention.

With certain caveats, as discussed, Romantown did emerge as a strong, competent community, willing and able to manage the dispersal of new settlements of asylum seekers despite incidences of resident disapproval and limited resources. The case study revealed the existence of robust and active informal agency structures alongside the more visible formal ones. However, this resulted in the workings of community governance being harder to recognise as asylum groups retreated away from the public arena to form their own forum.

The ethnographic approach used here was able to illuminate the micro-social of community dynamics crucial to this line of enquiry which is complemented by the unique position of resident/researcher.

description: We report a detailed account of the phase diagram of a recently introduced model for non-equilibrium wetting in 1+1 dimensions [Phys. Rev. Lett. 79, 2710 (1997)]. A mean field approximation is shown to reproduce the main features of the phase diagram, while providing indications for the behaviour of the wetting transition in higher dimensions. The mean field phase diagram is found to exhibit an extra transition line which does not exist in 1+1 dimensions. The line separates a phase in which the interface height distribution decays exponentially at large heights, from a superexponentially decaying phase. Implications to wetting in dimensions higher than 1+1 are discussed.

description: James Alfred Gawthorpe was my grandfather. He had a son called James Thomas who was my father. I have photographs of both of them. I believe my grandfather served in the First World War but I don't know where or in what capacity.

I have had passed down to me some medals. Some relate to the Second World War and some to the First World War. I also have an official document issued by the Board Trade which is authority for Charles William Dovener to wear the following medals and ribbons: British War Medal ribbon, Mercantile Marine Medal ribbon, British War Medal (and clasp) and Mercantile Marine Medal. One of the medals I have is the Mercantile Marine Medal so that is presumably his.

But who was Charles William Dovener? I had no idea. I have a photograph of him which can be identified as being him as it has his seaman's number on it; the same number is on the authorisation document for his medals. Bringing the objects to the digital collection day prompted an investigation to see if Charles William Dovener could be identified. It turns out he is one of my great grandfathers, being the father in law of James Alfred Gawthorpe. A report of the investigation has been added to the objects along with two partial family trees.

description: Stephen Hawking's contributions to the understanding of gravity, black holes and cosmology were truly immense. They began with the singularity theorems in the 1960s followed by his discovery that black holes have an entropy and consequently a finite temperature. Black holes were predicted to emit thermal radiation, what is now called Hawking radiation. He pioneered the study of primordial black holes and their potential role in cosmology. His organisation of and contributions to the Nuffield Workshop in 1982 consolidated the picture that the large-scale structure of the universe originated as quantum fluctuations during the inflationary era. Work on the interplay between quantum mechanics and general relativity resulted in his formulation of the concept of the wavefunction of the universe. The tension between quantum mechanics and general relativity led to his struggles with the information paradox concerning deep connections between these fundamental areas of physics. These achievements were all accomplished following the diagnosis during the early years of Stephen's studies as a post-graduate student in Cambridge that he had incurable motor neuron disease -- he was given two years to live. Against all the odds, he lived a further 55 years. The distinction of his work led to many honours and he became a major public figure, promoting with passion the needs of disabled people. His popular best-selling book A Brief History of Time made cosmology and his own work known to the general public worldwide. He became an icon for science and an inspiration to all.

description: Η επεμβατική ακτινολογία, αν και σχετικά νέα υποειδικότητα της ακτινολογίας, έρχεται να δώσει λύση στην σύγχρονη εποχή όπου υπάρχει η ανάγκη για μικροεπεμβάσεις (όπως βιοψίες και παρακεντήσεις) αλλά όχι ο απαραίτητος χρόνος και πολλές φορές ούτε οι διαθέσιμοι πόροι. Είναι μια ευρέως διαδεδομένη μέθοδος, η οποία μπορεί να πραγματοποιηθεί με όλες τις απεικονιστικές μεθόδους κάνοντας την με αυτόν τον τρόπο προσιτή και διαθέσιμη λύση σε κάθε γωνία του πλανήτη και σε όλες τις κοινωνικές τάξεις, ενώ παράλληλα καλύπτει μια πληθώρα επεμβάσεων που λύνει τα χέρια των χειρουργών. Σκοπός της παρούσας βιβλιογραφικής εργασίας είναι να διερευνηθούν οι επεμβατικές πράξεις, συγκεκριμένα οι καθοδηγούμενες με υπολογιστικό τομογράφο, οι τεχνικές με τις οποίες αυτές διενεργούνται, ο εξοπλισμός καθώς και τα οφέλη έναντι άλλων τεχνικών που χρησιμοποιούνται παραδοσιακά. Ένα πάρα πολύ σημαντικό κομμάτι της εργασίας αφορά τις “παγίδες” στις οποίες μπορεί να πέσει το επεμβατικό προσωπικό κατά την διεκπεραίωση κάποιας επέμβασης. Η πραγματοποίηση επεμβάσεων χωρίς επαρκή προκαταρκτικό έλεγχο και σχεδιασμό μπορεί να αποφέρει σοβαρά ανεπιθύμητα περιστατικά και για αυτόν τον λόγο έχουν θεσμοθετηθεί εξειδικευμένα μέτρα ασφαλείας καθώς και λίστες οδηγιών με σκοπό την βελτιστοποίηση των πρακτικών. Επιπλέον μελετάται η λαμβανόμενη δόση ακτινοβολίας, τόσο από τον ασθενή όσο και από το επεμβατικό προσωπικό. Η δόση της ακτινοβολίας που λαμβάνεται είναι μια πάρα πολύ σημαντική παράμετρος, η οποία πρέπει πάντοτε να συνυπολογίζεται κατά τον σχεδιασμό των επεμβάσεων με βάση τα υπάρχοντα πρωτόκολλα, την νομοθεσία που ισχύει και πάντοτε με γνώμονα τον ασθενή. Τέλος γίνεται αναφορά στην σημαντικότητα του ρόλου του τεχνολόγου ακτινολόγου στην διεξαγωγή των επεμβατικών πράξεων.

description: Margaret Johnson was my grandmother. She wrote poems and I have two that she wrote about the Battle of Zeebrugge. I have a book entitled "The Blocking of Zeebrugge" by Captain Alfred Carpenter V. C. This was passed down to me from my great great uncle. I also have some pieces from a Hun Gotha plane brought down off Margate 22/08/1917. I am trying to find out more about ML262 (motor launch) which was used in the laying of smoke screens.

description: Lillian (Lily) Jane Weir was my great aunt. She served in Queen Mary's Army Auxiliary Corps with service number 20002. She was mentioned in a Despatch from Field Marshall Sir Douglas Haig dated 16th March 1919. There is a short article in the Aberdeen Journal - Friday 29 August 1919 about the mention in despatch. It says that she was a telegraphist and had been on service since 1917 at Abbeville, Boulogne and Calais. Previously she had been a telegraphist at Peterhead Post Office. She never married and died in the early 1920s.
Non-compact String Backgrounds and Non-rational CFT

Subjects: subject: High Energy Physics - Theory (hep-th)

description: This is an introduction to the microscopic techniques of non-rational bulk and boundary conformal field theory which are needed to describe strings moving in non-compact curved backgrounds. The latter arise e.g. in the context of AdS/CFT-like dualities and for studies of time-dependent processes. After a general outline of the central concepts, we focus on two specific but rather prototypical models: Liouville field theory and the 2D cigar. Rather than following the historical path, the presentation attempts to be systematic and self-contained.

description: Within the framework of QED theory at finite temperature the thermal radiative corrections to spontaneous one-photon transition rates in hydrogen atom are investigated. The radiative one-loop self-energy corrections are described in the thermal case. Closed analytical expressions are derived and their numerical calculations for the spontaneous decay rate of the $ 2p $ state are carried out. Dominance of thermal radiative corrections to spontaneous Ly$_α $ decay rate over ordinary induced transition rate up to temperatures $ T < 6000 $ K is demonstrated.

description: The story is centred on two embroidered postcards that have been kept in the family. Exactly who the senders were has long been a mystery. They were in the possession of William Smith (1879-1964). He kept them in a little wooden book-shaped box which he brought with him when he came to live with my parents in the 1960s. They must have been important to him as they were among the few possessions he brought along.One was sent to Mrs. Smith at Ladymires, Ellon, Aberdeenshire, Scotland. It is signed "The old Keeper", with no name. It does have on it "No 408287 Sap G. B. R. E. Base, Rouen France". The postcard is not dated.I can identify Mrs. Smith. Her forenames were Mary Ann. Her husband, William, and my great grandfather, Peter, were brothers. My great grandfather and his wife, Jane, lived at Allathan Cottage in Maud, right opposite what was the mart. They are listed in the 1891 and 1901 censuses at that address. In the 1861 and 1871 censuses both Peter and William are listed at Mains of Allathan along with their parents and siblings.The postcard makes reference to Bill. This is William Smith (1879-1964) mentioned above. He was known as Willie. He was the son of Mary Ann and William Smith. I have a photograph of Willie which I took myself. I have a photograph of Mary Ann Smith which Willie brought with him when he came to stay with us.Recent research has found Sapper George Bremner with Regimental Number 408287 in the Roll of Individuals entitled to the Victory Medal and British War Medal (found on Ancestry www.ancestry.co.uk, records from the National Archives). The roll is dated 1919. The Regiment or Corps is given as the Royal Engineers. The entry for George Bremner also indicates that he served in R. E. (T) with regimental number 463. T presumably indicates the Territorial Force. Searches of the Commonwealth War Graves Commission web site and of "soldiers Died in the Great War, 1914-1919" for George Bremner with regimental number 408287 have produced nil results. The conclusion is that he did survive the war. I recollect some talk in the family about a George Bremner. So we now know that the sender of the postcard was George Bremner.The second postcard is addressed to Elsie, dated 2.4.16 and signed 'Yrs A Armstrong'. I remember my family talking about Mr Armstrong. The writing on the two postcards is different. Elsie was the daughter of William (my great grandfather's brother, mentioned above) and Mary Ann, and was second youngest of 7 children. Elsie was born on 17/10/1881. The family lived at Mill of Allathan and later at Ladymires, both Ellon area.But who was Mr Armstrong? So far enquiries have failed to provide an answer to this question.
