description: Following nearly a century of research, it remains a puzzle that the low-lying excitations of metals are remarkably well explained by effective single-particle theories of non-interacting bands. The abundance of interactions in real materials raises the question of direct spectroscopic signatures of phenomena beyond effective single-particle, single-band behaviour. Here we report the identification of quantum oscillations (QOs) in the three-dimensional topological semimetal CoSi, which defy the standard description in two fundamental aspects. First, the oscillation frequency corresponds to the difference of semi-classical quasi-particle (QP) orbits of two bands, which are forbidden as half of the trajectory would oppose the Lorentz force. Second, the oscillations exist up to above 50K - in stark contrast to all other oscillatory components - which vanish below a few K. Our findings are in excellent agreement with generic model calculations of QOs of the QP lifetime. Since the only precondition for their existence is a non-linear coupling of at least two electronic orbits, e.g., due to QP scattering on defects or collective excitations, such QOs of the QP lifetime are generic for any metal featuring Landau quantization with multiple orbits. They are consistent with certain frequencies in topological semi-metals, unconventional superconductors, rare-earth compounds, and Rashba-systems, and permit to identify and gauge correlation phenomena, e.g., in two-dimensional materials and multiband metals.

description: $ $The critical current of a Josephson junction is an oscillatory function of the enclosed magnetic flux $Φ$, because of quantum interference modulated with periodicity $h/2e$. We calculate these Fraunhofer oscillations in a two-dimensional (2D) ballistic superconductor--normal-metal--superconductor (SNS) junction. For a Fermi circle the amplitude of the oscillations decays as $1/Φ$ or faster. If the Fermi circle is strongly warped, as it is on a square lattice near the band center, we find that the amplitude decays slower $\propto 1/\sqrtΦ$ when the magnetic length $l_m=\sqrt{\hbar/eB}$ drops below the separation $L$ of the NS interfaces. The crossover to the slow decay of the critical current is accompanied by the appearance of a 2D array of current vortices and antivortices in the normal region, which form a bipartite rectangular lattice with lattice constant $\simeq l_m^2/L$. The 2D lattice vanishes for a circular Fermi surface, when only the usual single row of Josephson vortices remains.

Demand for family planning among women VCT clients: The need for Integration, Dessie town, Northeast Ethiopia
Creators: name: Emaway, Dessalew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Background - Integrating family planning services with HIV/AIDS services such as Voluntary Counseling and testing (VCT) is imperative in preventing unintended pregnancy, reducing number of AIDS orphans, preventing vertical transmission of HIV and sexually transmitted infections including HIV/AIDS. Information lacks on the family planning needs of VCT clients. It is essential to determine the extent of demand and provision of family planning in VCT settings as well as the potential opportunities & challenges of integrating family planning services with VCT. Objective - To assess the demand for family planning among VCT clients and the integration of family planning services with voluntary counseling and testing services. Methods- A facility based cross-sectional study was carried out in VCT centers in Dessie town, Northeast Ethiopia between December, 2006 and February, 2007. The study participants were female VCT clients who are in reproductive age group. The study employed both quantitative and qualitative study methods. The data were entered, cleaned and analyzed using SPSS statistical soft ware version 11. Result- Of the 422 female VCT clients participated in the study, 11.8% were counseled for family planning. VCT centers owned by NGOs were more likely to counsel their clients on family planning than governmental VCT centers: [AOR (95%CI) = 7.28 (2.07, 25.58)]. Great proportion of VCT clients (90%) want either to limit or to postpone child bearing. Among 166 sexually active clients 35% were current users of family planning methods and out of 384 non users of family planning methods 60% intended to use in the future. The unmet need for family planning among sexually active clients was 55%. The sero-status of the client was not significantly associated with the extent of family planning counseling and the level of unmet family planning need. Multivariate analysis showed that those who were in the age groups 15-19 and 20-24 years were more likely to have high unmet need for family planning as compared to those who were beyond 24 years: [AOR (95%CI) =6.46 [1.65, 25.33], and 5.46 (1.64, 18.20)], respectively. Ninety eight percent of clients and majority of counselors supported provision of family planning services at VCT centers. Though the existing policies, strategies and guidelines seem to be supportive to integration of family planning services with VCT services, the documents do not adequately and explicitly mentioned on what and how to implement. Recommendations- Provision of family planning services at VCT centers, as well as reviewing of the existing guidelines and developing of the new one is essential.

description: Recently, a concept of generalized multifractality, which characterizes fluctuations and correlations of critical eigenstates, was introduced and explored for all ten symmetry classes of disordered systems. Here, by using the non-linear sigma-model field theory, we extend the theory of generalized multifractality to boundaries of systems at criticality. Our numerical simulations on two-dimensional (2D) systems of symmetry classes A, C, and AII fully confirm the analytical predictions of pure-scaling observables and Weyl symmetry relations between critical exponents of surface generalized multifractality. This demonstrates validity of the non-linear sigma-model field theory for description of Anderson-localization critical phenomena not only in the bulk but also on the boundary. The critical exponents strongly violate generalized parabolicity, in analogy with earlier results for the bulk, corroborating the conclusion that the considered Anderson-localization critical points are not described by conformal field theories. We further derive relations between generalized surface multifractal spectra and linear combinations of Lyapunov exponents of a strip in quasi-one-dimensional geometry, which hold under assumption of invariance with respect to a logarithmic conformal map. Our numerics demonstrate that these relations hold with an excellent accuracy. Taken together, our results indicate an intriguing situation: the conformal invariance is broken but holds partially at critical points of Anderson localization.

description: Cosmological $N$-body simulations are the standard tool to study the emergence of the observed large-scale structure of the Universe. Such simulations usually solve for the gravitational dynamics of matter within the Newtonian approximation, thus discarding general relativistic effects such as the coupling between matter and radiation ($\equiv$ photons and neutrinos). In this paper we investigate novel hybrid simulations which incorporate interactions between radiation and matter to the leading order in General Relativity, whilst evolving the matter dynamics in full non-linearity according to Newtonian theory. Our hybrid simulations come with a relativistic space-time and make it possible to investigate structure formation in a unified framework. In the present work we focus on simulations initialized at $z=99$, and show that the extracted matter power spectrum receives up to $3\%$ corrections on very large scales through radiation. Our numerical findings compare favourably with linear analytical results from Fidler et al. (2016), from which we deduce that there cannot be any significant non-linear mode-coupling induced through linear radiation corrections.

Blindseilgeometrie

description: Eine Gruppe von 8-10 Personen mit verbundenen Augen. Ein langes Seil. Und eine Geometrieaufgabe, die zu lösen ist: Wie lässt sich ein Seil in Form eines möglichst großen Sechsecks ablegen – ohne dabei die Augen zu benutzen? Die Idee zur Blindseilgeometrie stammt ursprünglich vom Interaktionsspiel "Seilquadrat", welches in der Pädagogik bekannt ist (siehe z.B. Reiners 2004, S. 112). In diesem Spiel werden Teilnehmerinnen und Teilnehmer mit verbundenen Augen an einem an den Enden zu einem Ring verknoteten Seil platziert und erhalten die Aufgabe, mit dem Seil ein Quadrat zu bilden. Sie erreichen dies durch Sprechen mit anderen Teilnehmern, indem sie zunächst herausfinden, wie sie zueinander stehen, um sich und das Seil anschließend in die richtige Form zu bringen. Auf diese Weise sollen neben einer Veränderung der Wahrnehmung Kommunikation und Kooperation in der Gruppe geschult werden. Die Präzision des Quadrats wird beim "Seilquadrat" jedoch nur durch Schätzen erreicht. Die Blindseilgeometrie erweitert dieses Konzept, indem die geometrischen Objekte nicht nur ungefähr ausgelegt, sondern durch die Nutzung ihrer mathematischen Eigenschaften möglichst präzise konstruiert werden sollen. Wie in der unten vorgestellten Lösung deutlich wird, unterscheidet sich diese Art der Konstruktion von der üblichen Zirkel-und-Lineal-Konstruktion in gewisser Hinsicht. Der Schwerpunkt der Blindseilgeometrie bleibt jedoch, wie beim Seilquadrat, ein pädagogischer, sie bietet darüber hinaus jedoch einen ungewöhnlichen neuen Blickwinkel auf die Geometrie.

description: Cold atoms in an optical cavity have been widely used for quantum simulations of many-body physics, where the quantum control capability has been advancing rapidly in recent years. Here, we show the atom cavity system is universal for quantum optimization with arbitrary connectivity. We consider a single-mode cavity and develop a Raman coupling scheme by which the engineered quantum Hamiltonian for atoms directly encodes number partition problems (NPPs). The programmability is introduced by placing the atoms at different positions in the cavity with optical tweezers. The NPP solution is encoded in the ground state of atomic qubits coupled through a photonic cavity mode, that can be reached by adiabatic quantum computing (AQC). We construct an explicit mapping for the 3-SAT and vertex cover problems to be efficiently encoded by the cavity system, which costs linear overhead in the number of atomic qubits. The atom cavity encoding is further extended to quadratic unconstrained binary optimization (QUBO) problems. The encoding protocol is optimal in the cost of atom number scaling with the number of binary degrees of freedom of the computation problem. Our theory implies the atom cavity system is a promising quantum optimization platform searching for practical quantum advantage.

description: Understanding planetesimal formation is an essential first step to understanding planet formation. The distribution of these first solid bodies will drive the locations where planetary embryos can grow. We seek to understand the parameter space of possible protoplanetary disk formation and evolution models of our Solar System. A good protoplanetary disk scenario for the Solar System must meet at least the following three criteria: 1) an extended dust disk (at least 45 au); 2) formation of planetesimals in at least two distinct locations; and 3) transport of high temperatures condensates (i.e., calcium-aluminium-rich inclusion, CAIs) to the outer disk. We explore a large parameter space to study the effect of the disk viscosity, the timescale of infall of material into the disk, the distance within which material is deposited into the disk, and the fragmentation threshold of dust particles. We find that scenarios with a large initial disk viscosity ($α>0.05$), relatively short infall timescale ($T_{infall}<100-200$ kyr), and a small centrifugal radius ($R_C\sim0.4$~au; the distance within which material falls into the disk) result in disks that satisfy the criteria for a good protoplanetary disk of the Solar System. The large initial viscosity and short infall timescale result in a rapid initial expansion of the disk, which we dub the inflationary phase of the disk. Furthermore, a temperature-dependent fragmentation threshold, which mimics that cold icy particles break more easily, results in larger and more massive disks. This results in more "icy" than "rocky" planetesimals. Such scenarios are also better in line with our Solar System, which has small terrestrial planets and massive giant planet cores. Finally, we find that scenarios with large $R_C$ cannot transport CAIs to the outer disk and do not produce planetesimals at two locations within the disk.

Assessment of Factors Affecting Emergency Contraceptive Use and Prevalence of Unwanted Pregnancy among Female Students in Aksum University
Creators: name: Kahsay, Giziyenesh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Background: Emergency contraception (EC) is a method used to prevent the occurrence of pregnancy after unprotected intercourse. Unwanted pregnancy is a common problem among young unmarried women in Ethiopia where more than 60% of all pregnancies among adolescents is unwanted. Despite the availability this method, the prevalence of abortion is still high however, little is known about use of EC and factors influencing its use among girls attending higher education in Ethiopia. Objective: To assess magnitude and factors affecting emergency contraceptive use and prevalence of unwanted pregnancy among female students in Aksum University. Method: A cross-sectional quantitative study was done among 628 female under graduate students in Aksum University using structured self administered questionnaire. Multistage sampling technique was used to select participants. Data were cleaned and analyzed using SPSS version 21. Multivariate logistic regression analysis was done to identify independent predictors of EC and variables with p-value <0.05 considered as significant predictors. Result: A total of 617 students participated in this study. About quarter 147(23.8%) of the respondents ever had sexual intercourse and 29 (19.7%) where married, 26(26.5%) had sex had their sexual debut before 18 years. Fifty eight (39.5%) had been pregnant of whom 40(69%) were unwanted. Ever use of emergency contraceptive among the sexually active was 92 (62.6%). Respondents who visited religious place at least once a week were 3.76 times [AOR= 3.76; 95%CI, [2.482, 9.555], single 4.88 times [AOR= 4.88 95%; 1.937-12.288], respondents who have good knowledge on contraceptive 2.39 times [AOR=2.39 95% CI; 1.202, 4.743], study year 8.71 (AOR=8.71; 95% CI; 2.68, 28.8) more likely to use emergency contraceptive than their counterparts. Whereas those who did not discuss with their close friend on emergency contraceptive 63% [AOR= 0.37, 95%, CI; 0.193, 0.703] and those who never discussed on reproductive health issue with their family 42% [AOR= 0.58, 95%, CI0.321, 1.036] less likely to use emergency contraceptive than counter parts. Conclusions and recommendations: The prevalence of unwanted pregnancy is high while emergency contraceptive use among the sexually active students was low .This may put young girls at risk complication of unsafe abortion including premature death. There is a need to educate adolescents about EC use in averting unwanted pregnancy through creating and strengthening different clubs at schools.

description: This paper presents a detailed aeroacoustic investigation of a Controlled-Diffusion airfoil at near stall condition. The study aims at answering two research questions: identify the flow mechanism responsible for separation noise for an airfoil near stall conditions and whether the noise is generated by a dipole for airfoil close to stall and can be quantified by Amiet's diffraction theory. The study uses synchronized PIV, RMP and far-field microphone measurements to perform experiments at two chord based Reynolds numbers of about 150,000 and 250,000. The results show that when the airfoil is placed at a higher angle of attack, such as $15^{\circ}$, strong amplification of flow disturbance is seen, resulting in the rolling up of the shear layer in the aft-region of the airfoil, forming large coherent structures. While these rollers play a central role in the increase in noise due to flow separation, the flapping of shear layer does not contribute to the separation noise. The present study conclusively shows that separation noise is dipolar in nature, and that the quadrupolar contribution for low-speed airfoils at near-stall conditions can be neglected. However, the increase in flow disturbances measured close to the trailing-edge of the airfoil implies that the assumption of small amplitude disturbance is no longer valid, which is the central premise of the thin linearized airfoil theory. Outside the frequency range at which flow separation operates, Amiet's theory is able to predict the far-field noise even at high angles of attack.

description: We have conducted a search for L subdwarf candidates within the photometric catalogues of the UKIRT Infrared Deep Sky Survey and Sloan Digital Sky Survey. Six of our candidates are confirmed as L subdwarfs spectroscopically at optical and/or near infrared wavelengths. We also present new optical spectra of three previously known L subdwarfs (WISEA J001450.17-083823.4, 2MASS J00412179+3547133, ULAS J124425.75+102439.3). We examined the spectral types and metallicity subclasses classification of known L subdwarfs. We summarised the spectroscopic properties of L subdwarfs with different spectral types and subclasses. We classify these new L subdwarfs by comparing their spectra to known L subdwarfs and L dwarf standards. We estimate temperatures and metallicities of 22 late type M and L subdwarfs by comparing their spectra to BT-Settl models. We find that L subdwarfs have temperatures between 1500 K and 2700 K, which are higher than similarly-typed L dwarfs by around 100-400 K depending on different subclasses and subtypes. We constrained the metallicity ranges of subclasses of M, L and T subdwarfs. We also discussed the spectral type and absolute magnitude relationships for L and T subdwarfs.

description: Back ground: Since ancient time, plants have been used as indispensable sources of medicine and condiments. Nowadays, many traditional medicinal plants are incorporated in to modern medicine in many developed countries in the western world. However, in the developing countries like Ethiopia, traditional medicinal plants are still used in traditional manner without considering their effect, efficacy and dosage. T. schimperi is one of the traditional medicinal plants used for disease alleviation and food spice. This chronic study of toxicity was focused on evaluating the effects of chronic administration of aqueous leaf extracts of T. schympri on blood parameters and histology of liver and kidney in Wistar Rats. Methods and materials: Leaves of T. schimperi were collected from Bale Mountain, Oromia region and dried in the shade area at room temperature. The plant leaves then were powdered by pestle and mortar and macerated by aqueous water and shacked by orbital shaker. Finally, the macerated extract was filtered and freezed in deep freeze then dried in lyophilizer vacuum. For this study total of 40 rats, 20 male and 20 female rats, were used. Rats of each sex were randomly grouped into three experimental and one control group with 10 rats in each group 5 male and 5 females in separate cage. The experimental groups, II, III, and IV, were administered with the aqueous leaf extract at doses of 500, 1000, and 2000mg/kg, respectively for 180 days and then finally the rats were sacrificed humanly and liver and kidney and blood were taken for histopathology, hematology and biochemistry assessment. Results: The general behavior of the rats in treatment group was as normal as the control group. No statistical significant changes were seen between the mean bodyweight, liver and kidney weight and Blood parameters of experimental and control group of Wistar rats, however, considerable variations were observed between these parameters and mild focal mononuclear infiltration have been seen in the treatment of female rats treated with 1000and male rats treated with 2000mg/kg T. schimperi. Conclusion: Based on the findings of present chronic toxicity study it is difficult to draw conclusion with negative results because small sample size of animals was used rather it provides a baseline for future studies.

description: Highly concentrated protein solution were found to yield a large number of different phases, like amorphous aggregates, gels, crystals, or a liquid-liquid phase separation, which are all governed by the underlying protein-protein interactions in water. The interactions in dense protein solutions are highly complex, changes in the aqueous environment influence the inter- and intramolecular interactions, the protein-solvent interactions, and the solvent-solvent interactions. In this thesis, small angle X-ray scattering in combination with hydrostatic pressure perturbation was used to investigate the intermolecular interaction potential and the resulting phase behavior of dense lysozyme solutions. A reentrant liquid-liquid phase separation at elevated pressures was discovered, which could be ascribed to the solvent mediated protein-protein interactions.

Die Wechselwirkungen in dichten Proteinlösungen sind sehr komplex, Änderungen in der wässrigen Umgebung beeinflussen die inter- und intramolekularen Wechselwirkungen, die Protein-Lösungsmittel-Wechselwirkungen und die Wechselwirkungen im Lösungsmittel selbst. Röntgenkleinwinkelstreuung in Kombination mit hohen hydrostatischen Drücken wurde in dieser Arbeit genutzt, um das intermolekulare Wechselwirkungspotential und das daraus resultierende Phasenverhalten von hochkonzentrierten Lysozymlösungen zu untersuchen. Eine Wiedereintrittsverhalten der flüssig/flüssig-Phasentrennung bei erhöhten Drücken wurde entdeckt, welches sich auf die durch die wässrige Lösung vermittelte Protein-Protein-Wechselwirkung zurückführen lassen konnte.

Dessen Bedeutung – auch für die Elementarmathematik – steht der damit verbundene hohe kognitive Anspruch gegenüber. Dass Analogieprozesse auch mathematisch begabten Grundschulkindern schwer fallen, zeigen beispielsweise Ergebnisse der von uns durchgeführten Video-Studie zum Analogen Denken (ViStAD, Aßmus & Förster, 2013a, 2013b), deren Hauptziel es ist, Fähigkeiten zum Konstruieren und Nutzen von Analogien beim mathematischen Problemlösen als potenzielles Begabungsmerkmal zu überprüfen. Dafür schien es hilfreich, ein Modell zur Verortung von Analogieprozessen im Problembearbeitungsverlauf zu entwickeln, wobei wir zum einen theoriebasiert vorgegangen sind und zum anderen qualitativ gewonnene Ergebnisse der Studie genutzt haben. Ein erster Entwurf soll im Folgenden vorgestellt werden.

description: We extend the Loop Quantum Cosmology matter bounce scenario in order to include a dark energy era, which ends abruptly at a Rip singularity where the scale factor and the Hubble rate diverge. In the "deformed matter bounce scenario", the Universe is contracting from an initial non-causal matter dominated era until it reaches a minimal radius. After that it expands in a decelerating way, until at late times, where it expands in an accelerating way, thus the model is described by a dark energy era that follows the matter dominated era. Depending on the choice of the free parameters of the model, the dark energy era is quintessential like which follows the matter domination era, and eventually it crosses the phantom divide line and becomes phantom. At the end of the dark energy era, a Rip singularity exists, where the scale factor and Hubble rate diverge, however the physical system cannot reach the singularity, since the effective energy density and pressure become complex. This indicates two things, firstly that the ordinary Loop Quantum Cosmology matter bounce evolution stops, thus ending the infinite repetition of the ordinary matter bounce scenario. Secondly, the fact that both the pressure and the density become complex indicates probably that the description of the cosmic evolution within the theoretical context of Loop Quantum Cosmology, ceases to describe the physics of the system and possibly a more fundamental theory of quantum gravity is needed near the would be Rip singularity. We describe the qualitative features of the model and we also investigate how this cosmology could be realized by a viscous fluid and scalar field in the context of LQC.

description: Wie lernt jemand den Zahlenraum verstehen und rechnen ohne dabei Mengen, Zahlen oder Rechnungen visuell erfassen und darstellen zu können? Diese Arbeit zeigt beeinflussende Faktoren, didaktische Konzepte und die daraus hervorgegangenen Veranschaulichungsmittel für den Mathematikunterricht auf. Von den Anfängen der Blindenbeschulung bis in die Gegenwart wird diese Entwicklung anhand einer Inhaltsanalyse untersucht. Die Unterrichtung blinder Kinder beim Erwerb von mathematischen Kompetenzen stellt die Lehrpersonen immer wieder vor Probleme. In allen Zeitepochen suchen Blindenpädagoginnen und -pädagogen nach geeigneten Unterrichtsformen und Veranschaulichungsmitteln. Dabei gibt es Konzepte, die vor über 200 Jahren entstanden und heute noch aktuell sind. Veranschaulichungsmittel sind angesichts des technischen Fortschrittes reichhaltiger geworden und erleichtern die Teilhabe am Unterricht. Zum Schluss der vorliegenden Arbeit wird der Bogen zu mathematisch-didaktischen und blindenspezifischen Materialkriterien geschlagen. Die dargestellten Veranschaulichungsmittel werden anhand dieser Kriterien überprüft.

description: The study of mononuclear cell responses after human immunodeficiency virus type-l (HIV-l ) activation may help in providing some insight into the understanding of the pathogenic mechanisms of HIV infection or acquired immunodeficiency syndrome (AIDS)-related disorders. The secretion of three cytokines, interleukin-6 (IL-6) , tumor necrosis factor (TNF)-alpha, and interferon(IFN)-gamma by peripheral blood mononuclear cells(PBMC) was determined after in vitro stimulation with heat -inactivated HIV-I antigens, using cytokine-specific monoclonal antibodies and an indirect immunofluorescence technique. HIV-l antigen stimulation of PBMC from healthy donors did not induce the intracellular accumulation of IL-6, TNF-alpha, or IFN-gamma. Similarly, cells from asymptomatic HIV-infected subjects did not result in cytokine production either spontaneously or f ollowing stimulation with HIV antigen. After activation with mitogen o r antigen,cells from HIV-infected persons produced amounts of IL-6, TNF-alpha and IFN-gamma comparable to that of cells from healthy individuals. Furthermore, co-st imulation o f normal PBMC with HIVantigen plus L.donovani resulted in intracellular accumulation of IL-6 and TNF-alpha comparab~ e to that of cells that were activated with Leishmania antigen alone. Heat-inactivated HIV-l antigen does n o t appear to induce or modulate cytokine production by PBMC. A defect in cytokine production is also accompanied by i nh ibition of PPD-induced lymphoproliferative responses . Elevated levels o f serum cytokines have been demonstrated in patients with HIV infection indicating their role in the pathogenesis of HIV-associated infections. Theref ore, data from our results may partly support the idea that t he cause o f the abnormal l y increased cycokine levels in t he sera o f HIV-infected subjects x might be jue to a variety of opportunistic pathogens that these patients contract. As cytokines have been shown t o up-regulate HIV repl ication, our data addit i onally demonstrate a role f o r opportunistic infections in cytokine induced transactivation of HIV-l and disease progression.

description: The fourth of eight diaries written by Archie Wills during World War I. Describes Wills’ experience at Witley Camp as well as his training at Woolwich, both located in England between February and August 1917. Wills describes the daily life of the soldiers at the Witley training camp, which consisted of parades and field exercises. The men are trained in the use of gas helmets. The diary illustrates the hardships endured by the soldiers, such as the wet and cold weather, lack of baths due to broken pipes and freezing temperatures and insufficient rations. During their spare time the men explore the surrounding areas and socialize with the locals. By March 13th Wills and two of his friends begin the publication of their paper “O-Pip”, releasing the first volume in April 1917. By the end of June Wills begins a 6-week training course in Woolwich. He returns to Witley camp on August 13th 1917.

description: In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently isolated are thus interesting, allowing us to distinguish between internal and external processes affecting the galactic structure. However, current observational limits may obscure crucial information in the low-mass or low-brightness regime. We use optical imaging of a subsample of the AMIGA catalogue of isolated galaxies to explore the impact of different factors on the structure of these galaxies. We study the type of disc break as a function of the degree of isolation and the presence of interaction indicators like tidal streams or plumes only detectable in the low surface brightness regime. We present deep optical imaging of a sample of 25 isolated galaxies. Through careful data processing and analysis techniques, the surface brightness limits achieved are comparable to those to be obtained on the 10-year LSST coadds. The extreme depth of our imaging allows us to study the interaction signatures of 20 galaxies, given that the presence of Galactic cirrus is a strong limiting factor in the characterisation of interactions for the remaining 5 of them. We detect previously unreported interaction features in 8 (40%) galaxies in our sample. We identify 9 galaxies (36%) showing an exponential disc (Type I), 14 galaxies (56%) with down-bending (Type II) profile and only 2 galaxies (8%) with up-bending (Type III) profiles. Isolated galaxies have considerably more purely exponential discs and fewer up-bending surface brightness profiles than field or cluster galaxies. We suggest that major mergers produce up-bending profiles while a threshold in star formation probably forms down-bending profiles. Unperturbed galaxies, evolving slowly with a low star formation rate could cause the high rate of Type I discs in isolated galaxies observed.
