Higher school certificate chemistry in Tasmania : the last two decades : a study of the changing pattern of HSC chemistry in Tasmania in the period 1966-1988
Creators: name: Calcraft, PN
Publisher: name: University Of Tasmania
Year: 2023

description: Chemistry at the Higher School Certificate level has changed dramatically in the last twenty years. This thesis is concerned with those changes, the reasons for the changes and the way they have been brought about. The changing pattern of student intake is studied first on a world-wide basis and then from the particular, view of the Tasmanian scene. Then follows an account of the many and varied changes to the curriculum, examinations, and assessment techniques. The effect of these-changes on student numbers is also correlated. The period 1966 - 1988 has seen a progressive change from a stereo-typed traditional chemistry course to the more conceptual CHEM Study Course and finally a truly Australian developed course. These changes are studied in depth. During the same period the student population has changed tremendously. In the 1960's students were faced with a massive load of rote-learning and a practical experience that was very limited in scope. Today's students are allowed to take the text book into the examination and carry out many diverse experiments in the laboratory. These facets are considered and from questionnaire material the reactions of both students and teachers are given. Changes from a complete external assessment to the present half external and half internal have taken place progressively over this period. This has affected the teaching methods particularly regarding methods of assessment. The changing nature of the student population in the Years Eleven and Twelve has caused much thought and debate. Changes to Chemistry curricula have attempted to cope for the varying student intake. These changes are documented and discussed. The roles of both the University of Tasmania and the Schools Board of Tasmania have played a very important part over the period and help from both parties has been readily forthcoming and is well documented. In conclusion the thesis, is in effect the \Tasmanian Chemistry Story\". The major changes which have taken place over the last two decades are mainly unknown to a large percentage of the teaching staff in Tasmania and so it is believed that a document of this type may serve as both a reminder of the past and guide to the future."

description: Successful inventory management is the key for effective operation and customer satisfaction in supply chain. This dissertation explores the impact of data mining techniques in backorder predictions. More precisely, the study aims to address the effects of the application of undersampling and oversampling methods on the predictive accuracy of machine learning models. Weka tool is utilized to execute machine learning algorithms for data mining tasks such as data preparation and classification. The results were compared to identify the most suitable model by evaluating metrics including accuracy, F-measure and AUC-ROC values. The findings point out the importance of data mining approach for the optimization of decision-making on inventory management. This work contributes to the highlighting of the benefits of data-driven decision-making in supply chain operations and offers insights for future research.

Year: 2019

description: Als Reaktion auf das (transhumanistische) Postulat, dass die Technologien des Human Enhancement das menschliche Dasein derart fundamental erschüttern, dass nicht mehr vom Menschen gesprochen werden könne und der Humanismus seine Legitimation verloren habe, verfolgt diese Arbeit die Frage, inwiefern Praxen des Human Enhancement im Horizont Helmuth Plessners Konzepts der Exzentrischen Positionalität als Subjektivierungsprozesse verstanden werden können.
Einer hermeneutischen Methodologie folgend werden sieben Thesen der wechselseitigen Sinngebung von Subjektwerdung (als Allgemeines) und Human Enhancement (als Konkretes) aufgestellt und hinsichtlich ihrer Gültigkeit und Einschränkungen diskutiert. Die daraus gewonnenen Erkenntnisse bestehen erstens in einer Problematisierung der These, dass der Humanismus seine Legitimation verloren habe, heben zweitens die Bedeutung der Position des Subjektes für seine Subjekthaftigkeit und Freiheit hervor, erarbeiten drittens ein dialektisches Verständnis von Technologie im Horizont der Subjektwerdung und generieren viertens eine Hypothese zur Notwendigkeit von Alterität für die Subjektwerdung.
description: Answering to the transhumanist claim that due to technologies of human enhancement humanism has lost its legitimation, this paper follows the question of how practices of human enhancement can be understood as a process of subjectification within Helmuth Plessners framework of the eccentric position.
Taking a hermeneutical approach this paper discusses seven theses about how the practice of human enhancement can be understood as a specific form of subjectification. First of all the results suggest a refutation of the claim that humanism has lost its legitimation. Second they draw attention to the fundamental meaning of the subject’s position for its status as a subject and its freedom. Third they compile a dialectic understanding of technology. Fourth they posit a hypothesis about the necessity of alterity for the process of becoming a self-aware subject.

description: The self-consistent Green's functions method is employed to study the spectroscopic factors of quasiparticle states around 16O, 28O, 40Ca and 60Ca. The Faddeev random phase approximation (FRPA) is used to account for the coupling of particles with collective excitation modes. Results for 16O are reviewed first. The same approach is applied to isotopes with large proton-neutron asymmetry to estimate its effect on spectroscopic factors. The results, based on the chiral N3LO force, exhibit an asymmetry dependence similar to that observed in heavy-ion knockout experiments but weaker in magnitude.

description: We show that the gauge invariant treatment of the Schwinger-Dyson equations of QCD leads to an infrared finite gluon propagator, signaling the dynamical generation of an effective gluon mass, and a non-enhanced ghost propagator, in qualitative agreement with recent lattice data. The truncation scheme employed is based on the synergy between the pinch technique and the background field method. One of its most powerful features is that the transversality of the gluon self-energy is manifestly preserved, exactly as dictated by the BRST symmetry of the theory. We then explain, for the first time in the literature, how to construct non-perturbatively a renormalization group invariant quantity out of the conventional gluon propagator. This newly constructed quantity serves as the natural starting point for defining a non-perturbative effective charge for QCD, which constitutes, in all respects, the generalization in a non-Abelian context of the universal QED effective charge. This strong effective charge displays asymptotic freedom in the ultraviolet, while in the low-energy regime it freezes at a finite value, giving rise to an infrared fixed point for QCD. Some possible pitfalls related to the extraction of such an effective charge from infrared finite gluon propagators, such as those found on the lattice, are briefly discussed.

description: Saccular mycotic aorto-iliac aneurysms are rare but, when ruptured, they are an important life-threatening condition. We present the case of a 52 years-old male transferred from another hospital and admitted to the emergency room with a ruptured iliac artery aneurysm. He complained of persistent fever and abdominal discomfort that swiftly established as hemorrhagic shock. Image study with computed tomographic angiography revealed a ruptured left common iliac artery saccular aneurysm. The patient was instantaneously and successfully submitted to endoaneurismorraphy of the hypogastric artery, common and external iliac artery ligation and construction of an extra anatomic bypass, right to left femorofemoral bypass. Blood culture revealed a Streptococcus anginosus and the patient received appropriate targeted antibiotics. Post-operative period was uneventful and the patient discharged ten days after admission. He has now eleven months of follow up with no intercurrences. Even though surgical approach carries a relative risk of perioperative morbidity, it is a feasible and durable solution for extreme situations like the one here described.

description: The management of abdominal aortic aneurysms, especially ruptured abdominal aortic aneurysms, continues to challenge vascular surgeons. A ruptured abdominal aortic aneurysm is associated with a high mortality rate. If cardiopulmonary resuscitation is required before surgical repair, mortality rates are said to be even higher. However, cardiac arrest in patients with ruptured abdominal aortic aneurysm does not accurately predict a nonsalvageable state or preclude functional survival. In these cases, agressive management may be the only hope for survival, and cardiac arrest should not as such contraindicate repair. The objective of this study is to present a successful case of repair of ruptured abdominal aortic aneurysm after cardiac arrest.

description: The current flow from the bulk is due to the anomaly on the brane-but the absence of current flow is not, necessarily, due to anomaly cancellation, but to the absence of the chiral zero modes themselves, due to the existence of the layered phase. This can be understood in terms of the difference between the Chern-Simons terms in three and five dimensions. Thus the anomaly cancellation in four dimensions, which is essential for shielding the boundary from quantum effects within the bulk, makes sense only along the transition line between the layered and the Coulomb phase, which, in turn, requires the presence of a compact U(1) factor for the gauge group.

title: How can the UK government's Rwanda Policy be legal under international asylum law?
Creators: name: Owuor, Vicky Akinyi
Year: 2023

description: Asylverfahren (oder Teile hiervon) an Drittstatten auszulagern – zu externalisieren – ist kein neues Phänomen. Die Veröffentlichung des Abschlusses eines Memorandum of Understanding die Vereinbarung einer Asyl- Partnerschaft zwischen den Regierungen des Vereinigten Königreichs auf der einen und Ruandas auf der anderen Seite betreffend am 14. April 2022 resultierte in Behauptungen, dass eine solche Vereinbarung internationales Recht verletzen würde. Diese Arbeit prüft drei wesentliche Fragen: das Konzept individueller Rechte im Rahmen des MOU, das Prinzip des Non-Refoulements bzw. des Sicheren Drittstaates sowie die Frage, ob eine MOU als Instrument für die Umsetzung einer solchen Vereinbarung dienen kann. Sämtliche verfügbaren Argumente, die UNHCR aber auch andere relevante Player vorgebracht haben, werden geprüft. Keines der Argumente gegen die Gültigkeit des MOU hält einer rechtlichen Prüfung stand. Ruanda erscheint weniger korrupt zu sein und ein besser entwickeltes Rechtssystem zu haben als eine Reihe europäischer Staaten. Es sind keine rechtlichen oder faktischen Argumente zum Vorschein gekommen, die es rechtfertigten würden, Ruandas Regierung die korrekte Anwendung internationalen Rechts abzusprechen.
description: It is not a new phenomenon for a country bound by the Geneva Convention to outsource (parts of) its asylum procedures to a safe third country. The publication of the conclusion of a Memorandum of Understanding for the provision of an asylum partnership agreement between the Governments of the United Kingdom and Rwanda by the UK government on April 14, 2022, prompted claims that such an agreement would violate international law. This thesis examines three main legal issues: the concept of individual rights under the MOU, the principle of non-refoulement / safe third country, and the question of whether an MOU can serve as a mechanism for implementing such an agreement. All available legal arguments presented by UNHCR, and other relevant parties are examined. None of the arguments raised against the validity of the MOU can withstand legal examination. Rwanda appears to have less corruption and a more developed system of the rule of law than a number of European countries. No legal arguments or facts have surfaced that would justify excluding the Rwandan government’s correct application of international legal norms.

description: The tumours of the pleura are a vast and diverse field. One of the lesser known and less common tumour is the solitary fibrous tumour of the pleura, representing about 5% of these types of tumours. The authors present the case of a woman admitted in the emergency department with symptoms of dizziness and vomits. Imaging studies show a giant thoracic mass on the left hemithorax, with a biopsy indicating a solitary fibrous tumour. The patient was referred for surgery, which was performed via thoracotomy. In the postoperative period she developed an acute pulmonary oedema secondary to lung reexpansion and fluid overload, with a good response to fluid restriction and intravenous diuretics.

description: Chest wall tumours are challenging subjects. In the present article we describe a case of a 51 year old female who developed an angiosarcoma eight years after radiotherapy treatment due to left breast cancer at age 41. She had resection of the anterior segments of the 3rd to 5thribs followed by chest wall reconstruction, using MatrixRib fixation system®, Marlex® mesh and latissimus dorsi muscle flap. After two years the angiosarcoma relapsed. Considering the predicted extent of the chest wall resection, a reconstruction using titanium plates was not an option, so we opted to shape neo-ribs of Methyl Methacrylate using rubber drains as a mold. It affords very good anatomical contour of the chest wall and more physiological function than other options, although only long-term follow-up and future studies will determine the performance of this method.

title: Enhancing the effectiveness of the Vietnamese judicial system in dealing with intellectual property rights cases toward the compliance with the TRIPS agreement
Creators: name: Nguyen, Viet Quoc
Publisher: name: University of Glasgow
Year: 2008
Subjects: subject: IPRs enforcement, judicial effectiveness, judicial organisation, legal knowledge, legal proceedings

description: The question of the thesis is ‘How to enhance the effectiveness of the Vietnamese judiciary in dealing with intellectual property rights cases toward the compliance with requirements of the TRIPs Agreement?’. The critical themes in this thesis are how a developing country at the low level of development as in the case of Vietnam, with various distinctiveness in term of economy, society, culture, politics, or legality can enhance its judicial effectiveness in dealing with IP cases in order to fulfil its international obligations under TRIPs Agreement.

Despite the importance of the issue, there has not been any research on the first integration of Vietnamese judiciary in line with international regulations on IPRs protection and enforcement applicable to all WTO member states. This thesis will also examine impacts of this international compliance for the Vietnamese judiciary in particular, and to this South East Asian country in general.

After analysing the critical situation of IPRs infringements in Vietnam, which lie behind an impetus for change, the thesis will review the historical development of IPRs and main provisions of the TRIPs Agreement. Next, the thesis will examine the definition of judicial effectiveness in special reference to minimum standards as provided in the TRIPs Agreement. I will argue that judicial effectiveness in enforcing IPRs can not be improved to comply with the TRIPs Agreement unless judiciary’s capacity in preventing and deterring IP infringements, judicial organisation and knowledge, and other factors involving legal procedures are enhanced. In the light of above analysis, I will analyse the judicial organisation and legal knowledge in dealing with IP cases, and the adequacy of legislation concerning judicial measures for IPRs enforcement. I will also argue that any content of the reform of Vietnamese judiciary to comply with TRIPs Agreement must take into account, inter alia, the distinctiveness of Vietnamese judiciary, and other unique factors of this country in terms of its economy, society, politic and culture.

The aim was to compare the properties of microvariability in both types of quasars. We detected optical microvariability in 5 RQQs and 4 CRLQs. Our results confirm that microvariability in RQQs may be as frequent as in CRLQs. In addition we compare microvariability duty cycles in different bands. Finally, the implications for the origin of the microvariations are briefly discussed.

An ab initio calculation of the potential energy curves of some excited electronic states of OH
Creators: name: Easson, Ian Whiteman
Publisher: name: University of British Columbia
Year: 2011

description: A series of ab initio calculations has been performed in the Born-Oppenheimer approximation for some electronic states of OH. Wavefunctions and energies are calculated variationally. The form chosen for the wave-function is a finite linear superposition of configurations. Molecular orbitals are formed by Schmidt-orthogonalizing the atomic orbitals, each of which is represented by a single Slater-type orbital. The variational parameters are the coefficients in the linear expansion of the wave-function, and the non-linear parameters [character omitted] of the Slater-type orbitals. Wavefunctions and potential energy curves are given for some of the lower-lying ²Σˉ and ²Σˉ and ²Πstates. One result of note is that the lowest ²Σˉ state is bound. This disagrees with an earlier calculation (Harris and Michels, 1969), but it is in accord with a recent interpretation of the spectrum (Pryce, 1971).

description: Supravalvular aortic stenosis is a rare congenital anomaly (less than 0.05% of all congenital heart defects). This aortic root anomaly consists in a narrow aortic lumen immediately above the aortic valve and represents the least common form of left ventricular outflow tract obstruction. Clinical presentation is usually in the first decades of life. In most cases, the aortic valve leaflets are morphologically normal. However, aortic insufficiency due the high systolic pressure proximal to the sinotubular junction is the most commonly abnormality described. There are very few cases described in the literature with concomitant valvular and supra-valvular aortic stenosis.

Year: 2023

description: Im Zuge der Masterarbeit mit dem Titel >Inszenierung von Erinnerungskulturen anhand unterschiedlicher Beispiele aus der Zeit des Nationalsozialismus“ wird das Thema Inszenierung von Erinnerungskulturen theoretisch sowie praktisch betrachtet und analysiert. Dabei stehen die folgenden Fragen im Zentrum des Interesses: Wie entstehen kulturelle Erinnerungen? Wie werden Erinnerungen von bestimmten Gedenkstätten und Orten der Erinnerung im Internet inszeniert? Wie werden Erinnerungen von diesen Gedenkstätten und Orten im Internet evoziert? Das Thema ist relevant und höchst aktuell. Erinnerungen aus der Vergangenheit begegnen uns tagtäglich. In Gedenkstätten, Museen sowie im Internet wird auf die Vergangenheit Bezug genommen. Was steht hinter den verschiedenen Orten der Erinnerungen und wie werden diese inszeniert? Diese Fragen sind relevant und aktuell, da Erinnerungen nicht objektiv nebeneinander stehen, sondern bestimmte Aspekte der Vergangenheit in den Mittelpunkt der Gesellschaft gestellt werden, während andere neben ihnen untergehen und keine Beachtung im öffentlichen Diskurs erhalten. Ein kritischer Umgang mit der Inszenierung der Vergangenheit erscheint somit essenziell, um ein aufgeklärtes und kritisches Bewusstsein für diese zu erlangen. Ziel der Masterarbeit ist es, mit Hilfe des theoretischen Inputs ein Verständnis für die verschiedenen Gedächtnistheorien und Erinnerungskulturen zu erwerben sowie diese kritisch zu betrachten, um im Anschluss die Inszenierung von Erinnerungskulturen anhand von zwei ausgewählten Beispielen aus der Zeit des Nationalsozialismus aufzuzeigen. Bei den ausgewählten Internetseiten handelt es sich um die Internetseiten des Anne-Frank-Hauses sowie die der KZ-Gedenkstätten Mauthausen. Im Fokus dabei stehen die Fragen, wie aufgrund der Inhalte bei den Adressat*innen Erinnerungen an die Vergangenheit evoziert werden und wie diese inszeniert werden.

IDENTIFICATION OF BIOMARKERS FOR THE ASSESSMENT OF FARM RUMINANT HEALTH STATUS
Creators: name: DILDA, FRANCESCA
Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: The aim of this PhD thesis was to identify biomarkers for evaluating the health of farm ruminants and possible the quality of products. A rapid identification and quantification of acute phase proteins (APPs) can provide useful information on the health status of animal. From a clinical perspective, the availability of a quick, and reliable, diagnostic marker specific for inflammatory diseases is of paramount importance. APPs can be employed in the assessment of animal health and welfare both ante- and post-mortem as an aid to meat inspection. This work can be divided into two principal studies: the first one focused on the localization of APPs in extra hepatic tissues; in particular we have analyzed the distribution of acute phase proteins in the bovine forestomachs and abomasums and then the expression of SAA and Hp RNA in bovine tissues (and evaluation of suitable reference genes). The second part was more focused on the search for specific inflammatory biomarkers; in turn, this part of the thesis can be sub-divided into 2 studies: Escherichia coli lipopolysaccharides and Staphylococcus aureus enterotoxin B relationship with in?ammatory microRNAs in bovine monocytes and the development of a highly sensitive sandwich ELISA to quantify the goat and bovine AGP and SAA in serum. Regarding the first part of our investigations we demonstrated the expression of the four APPs? mRNA. These results were confirmed by Western blot analysis followed by localization through immunohistochemistry. We have also identi?ed SAA and Hp?s mRNA in all analyzed tissues in non pathological conditions. In the second part of the thesis, we investigated the effect of Escherichia coli lipopolysaccharide (LPS) and Staphylococcus aureus enterotoxin B (SEB) on the expression of ?ve miRNAs involved in the in?ammatory response, including miR-9, miR-125b, miR-155, miR-146a and miR-223, in bovine CD14+ cells (monocytes). We obtained an up-regulation both miR-155 and miR-146a when cells were stimulated with LPS and a down-regulation of miR-125b, miR-155 and miR-223 after SEB stimulation, suggesting miRNAs as potential inflammatory biomarkers. The last part of the study was devoted to ELISA detection of APP. A precise and sensitive test to determine AGP content was developed as sandwich ELISA in serum of bovine and goats. A good analytical sensitivity was demonstrated. The test can detect a wide range of AGP concentrations. Yet, neither in goats nor in bovine species, the test managed to identify the animals with disease. Regarding SAA, a novel immunoassay to specifically detect SAA in ruminants' serum was developed, but the present results must still be regarded as preliminary.

description: Introduction: Gluteal pseudoaneurysms are extremely rare and respond to pelvic trauma, penetrating wounds, inflammation or infection in the gluteal region. Clinical cases: Two men, 73 and 82 years respectively, who presented gluteal pseudoanerysm after drainage of perianal abscess the first one and after trauma the second one. In both cases the diagnosis was made by imaging tests (doppler ultrasound that was completed with computed tomographic angiography). The first one was successfully treated by ultrasound-guided injection of thrombin at the pseudoaneurysm sac. However, secondary treatment with thrombin injection and coil embolization was performed due to pseudoaneurysm reperfusion. The second one was successfully treated by embolization with hydrocoils through contralateral percutaneous femoral access as well as thrombin injection by direct ultrasound-guided puncture. Discussion: The incidence, presentation and surgical strategy are discussed. Current literature is also reviewed. Conclusion: Ultrasound scan is the first diagnostic test, computed tomographic angiography can give more topographic information. We found selective percutaneous embolization to be the treatment of choice. Open surgical treatment should be reserved for selected cases.

description: $P$-values have been the focus of considerable criticism based on various considerations. Still, the $P$-value represents one of the most commonly used statistical tools. When assessing the suitability of a single hypothesized distribution, it is not clear that there is a better choice for a measure of surprise. This paper is concerned with the definition of appropriate model-based $P$-values for model checking.

description: We have measured the local and global statistics of singularity velocity, v, and have related these through the spatial correlation function of v. The distribution of v is a mixture of a mesoscopic distribution of global change in the speckle pattern and the distribution for v for Gaussian random fields. When v is normalized by the standard deviation of the fractional intensity change, probability distributions and correlation function of v approach those for random Gaussian fields. These results are directly analogous to the statistics of transmitted intensity normalized by the total transmission and provide a unified framework for understanding statistics of speckle evolution and intensity.
Biological and ecological studies of two spotted spider mite (Tetranychus urticae Koch) and its control on hops in Tasmania
Creators: name: Cao, Yong

description: This study was initiated in March 1987 and completed in March 1989. Aspects of the general biology and ecology of Two Spotted Spider Mite (TSSM), Tetranychus urticae Koch, and its natural enemies in hop fields were investigated in the years 1987-88 and 1988-89. The investigation found that TSSM overwinters in hollow cavities of hop twigs in the litter around hop rootstocks. In late August to early September TSSM becomes active to lay eggs and progressively colonizes hop on the lower surface of hop leaves. The teneral female mites of new generations were found to move upward with elongation of hop vines.The distribution patterns of the mites on hops vary with time and mite stage. In early or mid-March, mites move downward along hop vines to seek overwintering refuges. The native predatory mite, Amblyseius longispinosus (Evans), was found to overwinter in the litter around the hop base. While the imported predatory mite, Phytoseiulus persimilis Athias-Henriot, cannot survive the Tasmanian winter. The effects of TSSM feeding on hop production and the control of TSSM on hops by various means were studied in the two consecutive seasons. If unchecked, the mite can cause as much as 30% loss in cone production. The loss is mainly due to the reduction in numbers of cones hop plants produce under high mite feeding pressure. Damage was most often associated with large numbers of immature TSSM. However, mite populations can be effectively suppressed by either multiple application of Summer-oil/ Limesulphur, or the release of predacious mite P. persimilis at appropriate time. A tolerance to mite feeding by hop plants was demonstrated. If insufficient numbers of cones are formed due to mite infestation, hop plants will produce larger cones to achieve maximum production. Two cultural activities can be effectively included into a TSSM control programme. Ploughing hop fields in late August - early September, after overwintering adults have moved onto notably thistles, can retard the build up of TSSM populations. Furthermore frequent use of overhead sprinkler irrigation of hop fields can result in suppression of TSSM populations. Several simple ways of assessing TSSM densities on hops were assessed in 1987-88 and were employed throughout this study. A 'modified counting method' was developed for estimating mite densities using a mite-brushing machine. Adult female mite densities were estimated in hop fields by the naked eye and these counts related to total numbers of all mite stages. In the phenology of the hop plant economic damage by mites was caused through infestation during the flowering phase and not by infestation of the earlier vegetation growth phase. Trial results indicated that application of Summer-oil during the post-vegetation phase could provide a potential alternative to conventional miticides.

description: Introduction: Chronic venous disease (CVD) of the lower limbs is a very prevalent medical condition with important socioeconomic repercussions. Small saphenous vein (SSV) incompetence, although less frequent than great saphenous vein (GSV) incompetence, presents a more challenging treatment, with higher rates of complication and recurrence. Objectives: To determine the incidence and associated risk factors of varicose veins recurrence in patients submitted, for the first time and exclusively, to SSV surgery with 5 years of follow-up. Methods: Retrospective analysis of all exclusively first-time SSV surgeries, at Angiology and Vascular Surgery Service of Hospital Beatriz Ângelo, between January 1st, 2013, and December 31st, 2014. In March 2019, the authors performed clinical and venous doppler ultrasound reassessment of all included patients. Results: A total of 23 limbs were evaluated, 56.5% were female and the mean age was 51.8 years. All patients were symptomatic and underwent ligation of the saphenopopliteal junction (SPJ), 26.1% and 43.5% had total and partial SSV stripping, respectively. After venous doppler ultrasound at 5-year follow-up, we found that 21.7% did not present a correct SPJ ligation due to failure to identify its location, with a statistically significant association between SPJ ligation and varicose vein recurrence. In follow-up, we also diagnosed GSV incompetence in 21.7% for the first time, which is in agreement with the fact that this is a chronic disease. Finally, we found that all patients with symptomatic recurrence at 5-year follow-up had CVD, however, some asymptomatic patients also had ultrasound changes. Conclusion: Routine preoperative localization of the SPJ by doppler ultrasound guidance could have an impact in minimizing varicose vein recurrence. Imaging recurrence does not always translate into clinical recurrence. Because this is a chronic disease, patients should keep general care to prevent disease progression, even after surgery.

description: Approximate Bayesian computation methods can be used to evaluate posterior distributions without having to calculate likelihoods. In this paper we discuss and apply an approximate Bayesian computation (ABC) method based on sequential Monte Carlo (SMC) to estimate parameters of dynamical models. We show that ABC SMC gives information about the inferability of parameters and model sensitivity to changes in parameters, and tends to perform better than other ABC approaches. The algorithm is applied to several well known biological systems, for which parameters and their credible intervals are inferred. Moreover, we develop ABC SMC as a tool for model selection; given a range of different mathematical descriptions, ABC SMC is able to choose the best model using the standard Bayesian model selection apparatus.

description: This paper is devoted to the study of the thermodynamic formalism for a class of real multimodal maps. This class contains, but it is larger than, Collet-Eckmann. For a map in this class, we prove existence and uniqueness of equilibrium states for the geometric potentials $-t \log|Df|$, for the largest possible interval of parameters $t$. We also study the regularity and convexity properties of the pressure function, completely characterising the first order phase transitions. Results concerning the existence of absolutely continuous invariant measures with respect to the Lebesgue measure are also obtained.
