description: Canonization of F(R) theory of gravity to explore Noether symmetry is performed treating R - 6(\frac{\ddot a}{a} + \frac{\dot a^2}{a^2} + \frac{k}{a^2}) = 0 as a constraint of the theory in Robertson-Walker space-time, which implies that R is taken as an auxiliary variable. Although it yields correct field equations, Noether symmetry does not allow linear term in the action, and as such does not produce a viable cosmological model. Here, we show that this technique of exploring Noether symmetry does not allow even a non-linear form of F(R), if the configuration space is enlarged by including a scalar field in addition, or taking anisotropic models into account. Surprisingly enough, it does not reproduce the symmetry that already exists in the literature (A. K. Sanyal, B. Modak, C. Rubano and E. Piedipalumbo, Gen.Relativ.Grav.37, 407 (2005), arXiv:astro-ph/0310610) for scalar tensor theory of gravity in the presence of R^2 term. Thus, R can not be treated as an auxiliary variable and hence Noether symmetry of arbitrary form of F(R) theory of gravity remains obscure. However, there exists in general, a conserved current for F(R) theory of gravity in the presence of a non-minimally coupled scalar-tensor theory (A. K. Sanyal, Phys.Lett.B624, 81 (2005), arXiv:hep-th/0504021 and Mod.Phys.Lett.A25, 2667 (2010), arXiv:0910.2385 [astro-ph.CO]). Here, we briefly expatiate the non-Noether conserved current and cite an example to reveal its importance in finding cosmological solution for such an action, taking F(R) \propto R^{3/2}.

description: Terahertz time-domain spectroscopy was used to obtain the line intensities and selfbroadening parameters of pure rotational lines of CO and N2O. The technique yields a direct measurement of an absorption spectrum from 0:2 THz to 3 THz, which is linear in amplitude, therefore allowing the profiles of multiple lines to be observed and quantified. The transitions studied in CO were from J′ = 3 <- 2 to J′ = 22 <- 21, and in N2O from J′ = 9 <- 8 to J′ = 52 <- 51. The gas spectra were measured at elevated pressures in the range of 0:7-5 bar for CO and 0:7-1:7 bar for N2O. The measured absorption spectra were analyzed assuming a Lorentzian lineshape and using a multiple-peak fitting procedure. The obtained values of the line intensities and self-broadening parameters are in good agreement with the HITRAN database.

description: WMAP and Planck may have uncovered several anomalies in the full CMB sky that could indicate possible new physics driving the growth of density fluctuations in the early Universe. These include an unusually low power at the largest scales and an apparent alignment of the quadrupole and octopole moments. In LCDM, the quadrupole and octopole moments should be statistically independent. These low probability features may simply be due to posterior selections from many such possible effects. If this is not the case, however, their combined statistical significance would be equal to the product of their individual significances. Ignoring the biasing due to posterior selection, the missing large-angle correlations would have a probability as low as ~0.1% and the low-l multipole alignment would be unlikely at the ~4.9% level; under the least favourable conditions, their simultaneous observation in the context of the standard model could then be likely at only the ~0.005% level. In this paper, we explore the possibility that these features are indeed anomalous, and show that the corresponding probability of CMB multipole alignment in the R_h=ct Universe would then be ~7-10%, depending on the number of large-scale Sachs-Wolfe induced fluctuations. Since the low power at the largest spatial scales is reproduced in this cosmology without the need to invoke cosmic variance, the overall likelihood of observing both of these features in the CMB is > 7%, much more likely than in LCDM. The key physical ingredient responsible for this difference is the existence in the former of a maximum fluctuation size at the time of recombination, which is absent in the latter because of inflation.

description: The present paper develops a general theory of quantum group analogs of symmetric pairs for involutive automorphism of the second kind of symmetrizable Kac-Moody algebras. The resulting quantum symmetric pairs are right coideal subalgebras of quantized enveloping algebras. They give rise to triangular decompositions, including a quantum analog of the Iwasawa decomposition, and they can be written explicitly in terms of generators and relations. Moreover, their centers and their specializations are determined. The constructions follow G. Letzter's theory of quantum symmetric pairs for semisimple Lie algebras. The main additional ingredient is the classification of involutive automorphisms of the second kind of symmetrizable Kac-Moody algebras due to Kac and Wang. The resulting theory comprises various classes of examples which have previously appeared in the literature, such as q-Onsager algebras and the twisted q-Yangians introduced by Molev, Ragoucy, and Sorba.

description: We develop in this paper the principles of an associative algebraic approach to bulk logarithmic conformal field theories (LCFTs). We concentrate on the closed $gl(1|1)$ spin-chain and its continuum limit - the $c=-2$ symplectic fermions theory - and rely on two technical companion papers, "Continuum limit and symmetries of the periodic gl(1|1) spin chain" [Nucl. Phys. B 871 (2013) 245-288] and "Bimodule structure in the periodic gl(1|1) spin chain" [Nucl. Phys. B 871 (2013) 289-329]. Our main result is that the algebra of local Hamiltonians, the Jones-Temperley-Lieb algebra JTL_N, goes over in the continuum limit to a bigger algebra than the product of the left and right Virasoro algebras. This algebra, S - which we call interchiral, mixes the left and right moving sectors, and is generated, in the symplectic fermions case, by the additional field $S(z,\bar{z})=S_{ab}ψ^a(z)\barψ^b(\bar{z})$, with a symmetric form $S_{ab}$ and conformal weights (1,1). We discuss in details how the Hilbert space of the LCFT decomposes onto representations of this algebra, and how this decomposition is related with properties of the finite spin-chain. We show that there is a complete correspondence between algebraic properties of finite periodic spin chains and the continuum limit. An important technical aspect of our analysis involves the fundamental new observation that the action of JTL_N in the $gl(1|1)$ spin chain is in fact isomorphic to an enveloping algebra of a certain Lie algebra, itself a non semi-simple version of $sp(N-2)$. The semi-simple part of JTL_N is represented by $Usp(N-2)$, providing a beautiful example of a classical Howe duality, for which we have a non semi-simple version in the full JTL image represented in the spin-chain. On the continuum side, simple modules over the interchiral algebra S are identified with "fundamental" representations of $sp(\infty)$.

description: Pnömoni, dünya genelinde özellikle çocuklar ve yaşlılar için ciddi tehditler oluşturan önemli bir sağlık sorunudur. Erken teşhis ve doğru tedavi, hastaların yaşam kalitesini ve hayatta kalma oranlarını artırmada kritik bir rol oynamaktadır. Tıbbi görüntüleme teknikleri, pnömoni teşhisinde vazgeçilmez araçlar olup, invaziv olmayan yöntemlerle hastaların iç organlarının görüntülenmesini sağlamaktadır. Son yıllarda, yapay zekâ ve özellikle derin öğrenme yöntemleri, tıbbi görüntü analizinde büyük ilerlemeler kaydetmiştir. Transfer öğrenme, büyük veri kümeleri ve güçlü işlemciler kullanarak tıbbi görüntülerden anlamlı özellikler çıkarmakta ve bu görüntüleri yüksek doğruluk oranlarıyla sınıflandırmaktadır. Bu çalışmada, transfer öğrenme yöntemi kullanılarak önceden eğitilmiş MobileNetV2 modeli ile pnömoni ve normal akciğer röntgen görüntüleri kişisel bilgisayarda sınıflandırılmıştır. Veri seti, Hindistan Bilim Enstitüsü, PES Üniversitesi, MS Ramaiah Teknoloji Enstitüsü ve Concordia Üniversitesi tarafından sağlanan röntgen görüntülerini içermektedir (doi: 10.17632/9xkhgts2s6.3). Modelin performansı doğruluk, hassasiyet, duyarlılık ve özgüllük gibi metriklerle değerlendirilmiş ve düşük hesaplama maliyetleriyle yüksek doğruluk sağladığı görülmüştür.  Eğitilen model, düşük maliyetli, yüksek performanslı ve taşınabilir bir gömülü sistem olan Nvidia Jetson Nano üzerinde çalıştırılmış ve bu platformdaki performansı incelenmiştir. Kişisel bilgisayarda modelin tahmin süresi 36.57 milisaniye, doğruluk %98.1, duyarlılık %97.8, özgüllük %98.5, kesinlik %98.9 ve F1-skoru %98.4 olarak elde edilmiştir. Jetson Nano platformunda ise tahmin süresi 111.2 milisaniye, doğruluk %97.8, duyarlılık %96.8, özgüllük %99.4, kesinlik %99.6 ve F1-skoru %98.2 olarak kaydedilmiştir. Çalışmanın bulguları, MobileNetV2 modelinin Nvidia Jetson Nano gömülü platformunda etkin şekilde çalışabileceğini ve yüksek performans sağladığını göstermektedir. Bu çalışma, pnömoni teşhisinde derin öğrenme ve gömülü sistemlerin entegrasyonunu kullanarak yenilikçi ve etkili bir çözüm sunmaktadır. Gelecekteki araştırmalar, daha büyük veri kümeleri ve çeşitli derin öğrenme modelleri kullanarak sınıflandırma performansını daha da artırabilir ve sağlık hizmetlerinin kalitesini ve erişilebilirliğini önemli ölçüde iyileştirebilir.

description: The knowledge of accurate spectroscopic parameters for a1Δg X3Σ− g band of molecular oxygen near 1.27 μ is very important in the field of remote sensing. Although, this band was studied by spectroscopists for over a century a lot of discrepancies still remain in the previously reported line positions and intensities. In this work the CWCavity Ring Down Spectroscopy (CW-CRDS) technique has been used to record the high sensitivity absorption spectrum of this band. The spectra were obtained between 7640 and 7917 cm−1 with “natural” oxygen and with samples highly enriched in 18O and 17O. They measured transitions belong to the a1Δg X3Σ− g (0-0) bands of 16O2, 16O18O, 16O17O, 17O18O, 18O2 and 17O2. The (0-0) bands of 16O2 and 18O2 show (previously undetected) electric quadrupole transitions with line intensities ranging from 1X10−30 to 1.9X10−28 cm/molecule. They are accompanied by the a1Δg X3Σ− g (1-1) hot bands which are also reported for the first time. Lines of the isotopologues containing 17O atom were observed to be plagued with unresolved hyperfine structure, especially in the 17O2 spectrum. Accurate spectroscopic parameters for the observed bands were derived from a global fit of the experimental line positions, combined with microwave and Raman measurements available in the literature.

description: Abstract
Advanced degrees for teachers demonstrate a high level of knowledge and dedication to their specialization areas, enabling them to change curriculum objectives, adapt teaching strategies, and take on leadership roles to implement the systemic changes in education they desire. This phenomenological research using focus group discussion (FGD) was used to examine the struggles and coping strategies employed by graduate students who are attending their master's degree program at the College of SPEAR at Mindanao State University (Main), Marawi. The key informants were thirteen [13] teachers enrolled in the master's degree program at the College of Sports, Physical Education, and Recreation (CSPEAR) during SY 2022-2023. Data gathered using a semi-structured interview guide was thematically analyzed. It was discovered that the participants began their trip from scratch, encountered stressful situations, but were able to balance their struggles with a safety net over their heads in order to eventually complete their studies. The researcher suggested that, in light of these findings, graduate studies programs should offer opportunities for socialization and stress-relieving activities including exercise, meditation, and creative pursuits. Engaging in positive social interactions, consistent exercise, and cultural activities can all lead to an increase in happiness and wellbeing. The model developed from this study may be used to more research, and more in-depth examination of the title can also be done using various techniques.

description: Nitrous acid, HONO, is a significant source of atmospheric HOx and the production of HONO may be responsible for the recycling of deposited NOy back into the atmosphere in active form. Many current techniques rely on wet-chemical extractive methods, but are potentially prone to interferences and have not always shown good agreement with optical techniques1. Spectroscopy offers an alternative method with greater specificity, however, the rotational-vibrational transitions of HONO in the mid-infrared region are not well studied. We present results from an experiment using a new tunable continuouswave quantum cascade laser absorption spectrometer. We measured the cis-HONO spectra between 1659 and 1660 cm-1 and the trans-HONO spectra near 1275 cm−1 (both at a resolution of about 0.001 cm−1). Absolute mixing ratios of total HONO were determined by catalytic conversion to NO followed by calibrated absorption spectroscopy. The effective line-strengths for cis-HONO near 1660 cm−1 were about a factor of 2.5 smaller than those listed in the ATMOS database, but line-strengths for trans-HONO around 1275 cm−1 agreed well with reported values.

Error Propagation From Line Parameters To Spectra Simulations. Illustration On High Temperature Methane

description: Astrophysical investigations generally need both complete and accurate spectroscopic databases. Despite continuous efforts in experimental and theoretical spectroscopic investigations, the lack of data in some spectral regions of interest is one of the main limitation of the presently available spectroscopic databases. Unfortunately information about missing data relevant to specific experimental conditions is rarely directly accessible from spectroscopic databases (focusing naturally on available data). Such information relies essentially on theoretical investigations which are equally limited to the present state of the art of modelling. The purpose of the talk is to show how multi-resolution models and rigorous error analyses can help overcoming such deficiencies. Rather than ignoring the spectral regions for which high-resolution line by line modeling is presently inaccessible, low-resolution modeling can be exploited for the sake of exhaustivity which represents a major issue in many astrophysical applications. In parallel, a rigorous quantitative estimation of uncertainties, also essential for applications, represents the second key feature of this approach. The error propagation from predicted line positions and intensities onto simulated spectra will be described in detail based on multi-resolution global analyses using an effective Hamiltonian approach. The procedure makes extensive use of statistical numerical experiments. It is illustrated on methane which is present in the atmospheres of many astrophysical objects. The modeling of the methane absorption coefficient in the near infrared and/or at high temperature remains a challenge mainly due to the intrinsic complexity of its ro-vibrational spectrum. The extremely large density of levels in highly excited polyads makes it very difficult (if not to say impossible) to envisage line by line modeling above say 10 000 cm−1 (http://hal.archives-ouvertes.fr/hal-00277904/fr/). In fact, the present state of the art of high-resolution modeling is limited approximately to the spectral region below around 5 000 cm−1. The example of methane at high temperature (Tvib = 2000 K and Trot = 296 K) will be presented as a typical situation where transitions from several hot band systems with quite different accuracies have to be considered in the same spectral window. Typical confidence bands for the absorption coefficient and transmission signal are plotted in the figures below (details at http://hal.archives-ouvertes.fr/hal-00473611/fr/). Prospects concerning possible improvements of the procedure and its computer implementation will be outlined.

description: We consider the rates of noise-induced switching between the stable states of dissipative dynamical systems with delay and also the rates of noise-induced extinction, where such systems model population dynamics. We study a class of systems where the evolution depends on the dynamical variables at a preceding time with a fixed time delay, which we call hard delay. For weak noise, the rates of inter-attractor switching and extinction are exponentially small. Finding these rates to logarithmic accuracy is reduced to variational problems. The solutions of the variational problems give the most probable paths followed in switching or extinction. We show that the equations for the most probable paths are acausal and formulate the appropriate boundary conditions. Explicit general results are obtained for small delay compared to the relaxation rate. We also develop a direct variational method to find the rates. We find that the analytical results agree well with the numerical simulations for both switching and extinction rates.

description: In an attempt to compute an accurate linelist for the water molecule, the high resolution emission spectrum of water vapor has been recorded between 50 and 600 cm−1 using a Bruker IFS 125HR Fourier transform interferometer and a continuous flow of water vapor rovibrationaly excited by an electrodless radio-frequency discharge. More than 6000 pure rotational lines within the eight first vibrational states were assigned up to J = 35. Rotational as well as rovibrational lines were identified for higher lying states belonging to the first hexad. About 1000 pure rotational transitions within vibrational states of the first hexad were assigned for the first time. The new data, along with a large body of high-resolution data, was fitted using the bending-rotation theoretical approach to compute line positions. In a preliminary analysis, the wavenumbers of 4185 new transitions involving all vibrational states up to the first triad were accounted for up to J = 27 with a root mean square value of 0.87 X 10−3 cm−1. Work is still in progress and we are hoping to account for the new data up to the second triad and beyond. In the paper, the new data will be presented and the results of the line position analysis will be given. The observed minus calculated residuals obtained in the present analysis will be compared to those retrieved using other calculated or experimental rovibrational energies.

description: We determine the singularity category of an arbitrary finite dimensional gentle algebra $Λ$. It is a finite product of $n$-cluster categories of type $\mathbb{A}_{1}$. Equivalently, it may be described as the stable module category of a selfinjective gentle algebra. If $Λ$ is a Jacobian algebra arising from a triangulation $\ct$ of an unpunctured marked Riemann surface, then the number of factors equals the number of inner triangles of $\ct$.

description: The spectroscopic parameters for the a1Δg X3Σ− g band of molecular oxygen near 1.27 μm were given in HITRAN almost since the inception of the database. This band is of fundamental importance in the field of remote sensing. Although, the spectral parameters were updated several times numerous uncertainties have remained. Even the most recent update (November, 2009), that was proven to be superior to previous versions of HITRAN in the atmospheric retrievals 1, leaves room for improvement. This includes not only correction of the existing parameters (for instance the J-dependence of line intensities for 16O18O) but also accounting for electric quadrupole transitions. The addition of the ΔJ=±2 electric quadrupole transitions was recently shown to be important 2. Also one has to evaluate, the correlation between the overlapping ΔJ=±1, 0 magnetic dipole and electric quadrupole lines. The (1-1) band of 16O2 and (0-0) band of 16O17O have intensities similar to quadrupole transitions, and therefore the reference spectroscopic data for these species is required. In order to provide accurate input parameters for calculation of line lists the CW-Cavity Ring Down Spectroscopy (CWCRDS) technique has been used to record the high sensitivity absorption spectrum of this band. The spectra were obtained between 7640 and 7917 cm−1 with “natural” oxygen and the absolute intensities of 377 oxygen transitions were measured. They include the a1Δg X3Σ− g (0-0) bands of 16O2, 16O18O and 16O17O. The (0-0) bands of 16O2 contain electric quadrupole transitions with line intensities ranging from 1X10−30 to 1.9X10−28 cm/molecule. The lines from (1-1) band were also measured.

description: Methyl chloride (CH3Cl) is one of the most abundant chlorine-containing molecules in the atmosphere. For this reason a recent update was performed in HITRAN for this molecule in the 0-2600 cm−1 region by Nikitin et al.1. CH3Cl has a rather strong signature at 3 μm which has been used recently by the Atmospheric Chemistry Experiment (ACE) satellite mission to produce the first study of the global distribution of methyl chloride in the upper troposphere and stratosphere 2. However it was mentioned that the CH3Cl line parameters are of very low quality in this spectral region in the HITRAN or GEISA databases 3. In this work we present a complete update of the line positions and of the (absolute) line intensities for CH3 35Cl and CH3 37Cl in the 3 μm region. At LADIR about 4000 line positions and 500 line intensities were measured for CH3 35Cl and CH3 37Cl using new high resolution FTS spectra (Bruker IFS 120) of methyl chloride. The theoretical model accounts for the interactions coupling the ν1 (l=0), ν4 (l=1), 2ν3+ν5 (l=1), 2ν5 (l=2) and 3ν6 (l=1 and l=3) vibrational states. In addition line shape studies are in progress.

description: Belirli bir bedel karşılığında devlet gelirlerinin bir kısmının kişilere devredilerek toplatılmasına iltizam denmektedir. İltizam sistemi Osmanlı İmparatorluğu’nda tımar sisteminin yerine uygulamaya konmuştur. İltizam sistemine geçişte dünyada yaşanan ekonomik ve toplumsal dönüşümlerin etkisi olmuştur. Bütçenin nakit ihtiyacından kaynaklı olarak uygulama alanları arttırılan bu sistemin başta olumlu taraflarının fazla olacağı düşüncesi hakimdir. Özellikle mültezimlerden paranın hemen ya da kısa bir süre zarfında alınacak olması, paranın hemen alınmasından kaynaklı olarak enflasyon ve ekonomik dalgalanmalardan etkilenmeyecek olması ve vergi toplamadaki işlem maliyetine katlanma zorunluluğunun olmaması iltizam sistemine geçişte önemli referans noktaları olmuştur. Fakat zaman içerisinde mültezimlerin kârlarını maksimum tutmak adına vergi mükelleflerinden yüksek tutarlarda vergi istemeleri, malikâne sistemine geçişle mültezimlerin haklarının 1-3 yıldan hayatta kaldıkları süre zarfına çıkarılması sistemin halk ve devlet adına taraflarını ortaya çıkarmıştır. Bununla birlikte mültezimle imzalanan anlaşmanın her an bozulacak ve daha fazla teklif veren bir mültezime verilme ihtimali, başta ihaleyi alan mültezimlerin kazanma hırslarını perçinlemiş ve bu durum tebaaya zarar vermiştir. Bu bağlamda 16. ve 17. yüzyıllarda Osmanlı İmparatorluğu’nun bütçe gelir ve giderleri incelendiğinde bütçe gelirlerinin istenilen ölçüde artmadığı, artan bütçe giderleri ile birlikte ciddi bütçe açıklarının oluştuğu görülmüştür.
Nonlinear variations in axisymmetric accretion

description: We subject the stationary solutions of inviscid and axially symmetric rotational accretion to a time-dependent radial perturbation, which includes nonlinearity to any arbitrary order. Regardless of the order of nonlinearity, the equation of the perturbation bears a form that is similar to the metric equation of an analogue acoustic black hole. We bring out the time dependence of the perturbation in the form of a Liénard system, by requiring the perturbation to be a standing wave under the second order of nonlinearity. We perform a dynamical systems analysis of the Liénard system to reveal a saddle point in real time, whose implication is that instabilities will develop in the accreting system when the perturbation is extended into the nonlinear regime. We also model the perturbation as a high-frequency travelling wave, and carry out a Wentzel-Kramers-Brillouin analysis, treating nonlinearity iteratively as a very feeble effect. Under this approach both the amplitude and the energy flux of the perturbation exhibit growth, with the acoustic horizon segregating the regions of stability and instability.

The Importance Of Being Earnest About Line Shapes

description: Recent advances in theoretical and experimental spectroscopy demonstrate that physical inadequacies in standard Voigt molecular line shape models degrade laboratory and atmospheric spectral curve-fitting retrievals even for state-of-the-art spectrometers. More sophisticated physics associated with molecular collisions (line mixing, speed dependence, narrowing etc.) are generally known, but the atmospheric and laboratory spectroscopy communities lack a comprehensive (validated) software required to compute the very accurate synthetic spectra needed for the retrieval process. For the remote sensing of important greenhouse gases (e.g. CO2, CH4 and H2O), these deficiencies must be corrected in order to achieve abundances with the 0.3% accuracies required for climate change science. We need an international effort to correct this situation.

Uncertainties Associated With Theoretically Calculated N2 Broadened Half-Widths Of H2O Lines

description: For many accurate atmospheric applications involving the water vapor molecule, it is desirable to know the half-widths and their temperature dependences better than a 3 % uncertainty for strong lines and 10 % for weaker lines1. Unfortunately, of all spectroscopic parameters in HITRAN for H2O, the self and air half-widths and their temperature dependences contain the largest uncertainties. Recently, in order to improve this situation, the H2O database in HITRAN has been updated. In developing this updated version, in cases where there are no half-width values to the desired accuracy available in the vast experimental literature, theoretically calculated values have been adopted. For many years researchers have used the Robert-Bonamy (RB) formalism and adopted a realistic potential model to derive these values. Because of the large number of potential matrix elements appearing in these calculations, one is forced to introduce cut-offs that may limit the accuracy attainable. To obviate the necessity of lower cut-offs, we recently reformulated the theory using the coordinate representation2. With different choices of the cut-offs used in the theoretical calculations, we have carried out extensive numerical calculations of the N2-broadend Lorentzian half-widths of the H2O lines using the modified RB formalism3. Based on these results, we are able to thoroughly check the convergence. We find that with lower cut-offs commonly used in the literature, one is able to obtain converged values only for lines with large halfwidths. Conversely, for lines with small half-widths much higher cut-offs are necessary to guarantee the convergence. We also analyze uncertainties associated with the calculated half-widths, and these are correlated as above. In general, the smaller the half-widths are, the poorer the convergence and the larger the uncertainty associated with them. For convenience, one can divide all H2O lines into three categories: large, intermediate, and small according to their half-width values. One can use this division to judge whether the calculated half-widths are converged or not, based on the cut-offs used, and also to estimate how large their uncertainties are. We conclude that with the current RB formalism for lines in category 1, one can achieve the accuracy requirement set by HITRAN while for lines in category 3, it is absolutely impossible to meet this goal.

description: We are interested in the robustness of a Liouville type theorem for a reaction diffusion equation in exterior domains. Indeed H. Berestycki, F. Hamel and H. Matano (2009) proved such a result as soon as the domain satisfies some geometric properties. We investigate here whether their result holds for perturbations of the domain. We prove that as soon as our perturbation is close to the initial domain in the $C^{2,α}$ topology the result remains true while it does not if the perturbation is not smooth enough.

description: This publication is part of a broader initiative aimed to introduce a systems approach to sustainability education: the "Green Hive" project, a cooperative partnership co-funded by the European Union under the Erasmus+ Programme. The project, presented in Chapter 1, aims to build a European Ecosystem for Sustainability Education (the Green Hive), composed of localised hubs for sustainability education established within Vocational Education and Training (VET) providers, namely the Green Combs. Hence, by introducing and piloting a more holistic and network-based approach, as well as a new value model to align multiple and relevant stakeholders across the system, the Green Hive will connect VET providers, learners and local communities across Europe, enabling knowledge exchanges at the local and transnational level, anticipating skills needs and, ultimately, empowering individuals and organisations to cooperate to innovate and co-create value.

The canvases presented in this publication are a component of the “Toolkit for the setup and management of Green Combs” developed by the project consortium with VET providers in Greece, Ireland, Italy, Romania and Spain. The Toolkit also includes a how-to guide and a Massive Open Online Course (MOOC) to support education and training entities in setting up, managing and growing their hubs for sustainability education.

This publication has received funding from the European Commission under Grant Agreement number 2022-2-IE01-KA220-VET-000097215, Erasmus+ Cooperation Partnership project "Green Hive".
Broken bodies: oral histories of infertility after the women’s liberation movement

description: Using oral histories with women born between 1946 and 1980, this article explores experiences and memories of infertility and pregnancy loss in the post-women’s liberation era. Infertility had a lasting impact on participants’ relationships with their bodies, expressed often in terms of ambivalence towards their physical selves and an embodied ‘broken-ness’. I historically contextualise these expressions of broken-ness to show the ongoing resilience of socially-constructed narratives that link womanhood with reproductive ability. The resilience of these attitudes suggests a continued need for critically interrogating cultural norms about gender and infertility in Australian society.
