description: Household air pollution is a leading risk factor for morbidity and premature mortality. Numerous cookstoves have been developed to reduce household air pollution, but it is unclear whether such cookstoves meaningfully improve health. In a controlled exposure study with a crossover design, we assessed the effect of pollution emitted from multiple cookstoves on acute differences in blood lipids and inflammatory biomarkers. Participants (n = 48) were assigned to treatment sequences of exposure to air pollution emitted from five cookstoves and a filtered-air control. Blood lipids and inflammatory biomarkers were measured before and 0, 3, and 24 hours after treatments. Many of the measured outcomes had inconsistent results. However, compared to control, intercellular adhesion molecule-1 was higher 3 hours after all treatments, and C-reactive protein and serum amyloid-A were higher 24 hours after the highest treatment. Our results suggest that short-term exposure to cookstove air pollution can increase inflammatory biomarkers within 24 hours.

description: Η χολοκυστεκτομή αποτελεί μία από τις συνηθέστερα εκτελούμενες χειρουργικές επεμβάσεις στον σύγχρονο κόσμο. Μετά την εφαρμογή της λαπαροσκόπησης, η λαπαροσκοπική χολοκυστεκτομή έχει επικρατήσει σαν μέθοδος εκλογής, μετατρέποντας την χολοκυστεκτομή σε επέμβαση «ρουτίνας». Αυτό όμως έχει επιφέρει και αύξηση στις διάφορες κακώσεις που προκύπτουν κατά τη διάρκεια της χολοκυστεκτομής. Μέσα από μία ανασκόπηση της βιβλιογραφίας, επιχειρούμε να εντοπίσουμε τις αγγειακές κακώσεις που μπορεί να προκύψουν κατά τη διάρκεια μίας χολοκυστεκτομής. Αναλύονται ξεχωριστά τα είδη αυτών των κακώσεων ανάλογα με το αγγείο που αφορούν, οι κλινικές εκδηλώσεις που αυτές προκαλούν αλλά και οι σύγχρονοι τρόποι αντιμετώπισής τους. Αρχικά παρατίθενται εισαγωγικές γνώσεις ανατομίας και φυσιολογίας που είναι απαραίτητες για την περαιτέρω κατανόηση των κακώσεων που προκύπτουν κατά τη χολοκυστεκτομή και στη συνέχεια αναλύεται το ειδικό μέρος των κακώσεων.
description: Cholecystectomy is one of the most commonly performed operations in the contemporary world. Since the introduction of laparoscopy, laparoscopic cholecystectomy has become the gold standard, transforming this operation into a “routine procedure”. Though, this has brought an increase in the various injuries that can happen during cholecystectomy. Herein, we are trying to reveal the vascular injuries that occur during cholecystectomy by means of a literature review. We analyze the types of injuries respective to the vessel injured, their clinical manifestations and the current ways of management and treatment. We start with the basic knowledge of anatomy and physiology that are necessary to understand the vascular injuries that can occur during cholecystectomy and then we proceed with the specific part of the vascular injuries.

description: We observe a narrow enhancement near 2mp in the invariant mass spectrum of ppbar pairs from radiative J/psi-->gamma ppbar decays. The enhancement can be fit with either an S- or P-wave Breit Wigner fuction. In the case of the S-wave fit, the peak mass is below the 2mp threshold and the full width is less than 30 MeV. These mass and width values are not consistent with the properties of any known meson resonance.

description: Reconstructing 3D distributions from their 2D projections is a ubiquitous problem in various scientific fields, particularly so in observational astronomy. In this work, we present a new approach to solving this problem: a Vienna inverse-Abel-transform based object reconstruction algorithm AVIATOR. The reconstruction that it performs is based on the assumption that the distribution along the line of sight is similar to the distribution in the plane of projection, which requires a morphological analysis of the structures in the projected image. The output of the AVIATOR algorithm is an estimate of the 3D distribution in the form of a reconstruction volume that is calculated without the problematic requirements that commonly occur in other reconstruction methods such as symmetry in the plane of projection or modelling of radial profiles. We demonstrate the robustness of the technique to different geometries, density profiles, and noise by applying the AVIATOR algorithm to several model objects. In addition, the algorithm is applied to real data: We reconstruct the density and temperature distributions of two dense molecular cloud cores and find that they are in excellent agreement with profiles reported in the literature. The AVIATOR algorithm is thus capable of reconstructing 3D distributions of physical quantities consistently using an intuitive set of assumptions.

description: There are various types of vertical coordinations in value chain. They are spot market, specification contract, relation based alliance, equity based alliance, and vertical integration. The characteristic of each type is explained and then compared each other. Varying with asset specificity, a process of deciding the type of vertical coordination is explained using technical efficiency and agency efficiency. Technical efficiency is related to production cost and economy of scale and agency efficiency is related with transaction cost and agency problem. The study presents empirical cases of vertical coordination by Doderam, a co-operative of porks and Halim, a company to raise, process, and marketing chicken. Relations of them with farmers are analyzed and suggestions are followed.

Our results show that the value of the branching ratio $Br(Z\to τl)$ is larger than that of $Br(Z\to μe)$ in all of the parameter space and there is $Br(Z\to τμ)\approx Br(Z\to τe)\simeq 2\times 10^{-14} $, which is far from the reach of present or future experiments.

description: Recently rural tourism has been drawing a growing interest as an alterative to solve the difficulties of korea's agricultural economy. The purpose of this study is to identify the effects of entrepreneurship on the performance of rural tourism. Based on previous studies, this paper derives a conceptual framework for causal relationship research. This study implemented regression analysis, and created a logistic regression model using the data collected from rural farms. The results of the empirical test tell us that at least at the present stage of development of rural tourism, entrepreneurship is a more important factor affecting the outcomes of rural tourism than any other factors, such as the operational competence of business. This paper suggests policy orientations which place high scores on customer-oriented components such as entrepreneurship, and marketing strategy rather than supplier-oriented components such as rural amenity, and support systems.

Development of FexN thin films with microcompression analysis
Creators: name: Muhammad Nadzri, Nur Izzati Binti

Year: 2020

description: This thesis explores the growth routes of metal nitrides based materials of binary and ternary nitrides. It is believe that this iron nitrides based materials exhibit interesting properties in term of electronic optical, thermal and magnetic properties. However, most experimental and analytical efforts in this research field have been carried out in the form of bulk samples and there was no research of these nitrides in thin films. Consider the unique characteristics of iron nitrides system, the binary and ternary nitrides of both FexN and FexWy-1N thin films were grown using electron beam physical vapor deposition method under metal rich conditions. There exist significant challenges for the development of both binary and ternary nitrides thin films. It required to remain stable during the growth in order to incorporate nitrogen in the system to obtain Fe-N system due to the nature of nitrogen of having strong triple bond. The first aspect of this thesis investigate the development of these nitrides by using four different methods. Results from XRD and XPS reveal that there were formation of iron oxides on the thin films and further XPS data shows the percentage of nitrogen is lower than expected. The highest content of iron was then selected to proceed with second phase of the project with the aim of developing iron nitrides thin films with thicker films under higher growth temperature. The formation of iron nitrides were found in the thin films with higher growth temperature. The XPS analysis that shows the presence of either Fe2+ or Fe3+ species in the sample and further investigation by TEM reveals the film hexagonal crystal structure which corresponds to Fe3N. An attempt of growing ternary nitrides were carried out with different iron to tungsten ratio. However, in this preliminary study, we only managed to obtain W-N composition with a limited amount of iron presence in the sample. It was found that either the iron has been oxidised or some iron oxides or tungsten oxides were formed during the synthesis Microcompression experiment was carried out on the thicker iron nitrides thin films in order to calculate their Young’s modulus. It was found that the value is still lower than the bulk samples which may be corresponds to misalignment between the pillar and the system during the experiments. However, it was observed that there was no deformation such as crack occurred on the thin films during this test. Further study shall be carried out to have a better understanding of these iron nitrides based thin films.

description: HEMISTOLITI + COMOSTOLITI
Hemistoliti and Comostoliti were both erected by Inoue (1961) as tribes. Hausmann (1996) summarized the differential features of these two groups, mentioned that some features of Comostoliti (e.g. the male genitalia) are reminiscent of Hemistoliti and stated that there is a close relationship between Comostoliti and Joditi. As in Sihvonen et al. (2011), the close relationship between Comostoliti and Hemistoliti, represented by the type genus of each, is fully supported here, validating the statement by Hausmann (1996). However, the monophyly of Hemistoliti is not supported, as Hemistola tenuilinea Alphéraky is sister to parts of Hemistoliti and Comostoliti. Therefore, we suggest that Comostoliti is a possible synonym of Hemistoliti and that further research, including more genera of Hemistoliti and Comostoliti, is needed. In this analysis, the close relationship between Comostoliti and Joditi is not directly supported, and the synonymization between Hemistoliti and Thalassoditi presented by Hausmann et al. (2016b) is not directly supported because the phylogeny of Hemitheini is not fully resolved.

description: This report analyses how much open space, in particular agricultural land, is utilized by photovoltaic plants which have been awarded the right to be subsidized within the framework of the Renewable Energies Act 2017. The research is based on individual data of successful bids in twelve tendering rounds from 2015 to 2018. Additionally, data of all plants which have been put into operation until November 2018 are analysed. This is a follow-up report of the reporting years 2016 and 2017. As a result from three tendering rounds in 2018, 807 hectares open space are expected to be utilized. Thereof, 449 hectares are presumably agricultural land. However, successful bids are often transferred to other locations than stated in the bids. Thus, estimating the utilization of agricultural land with the help of tendering data involves great uncertainties. It is therefore recommended to test the use of remote-sensing data in order to gain more significant results on the actual utilization of agricultural land.

title: Hardward and algorithm architectures for real-time additive synthesis
Creators: name: Symons, Peter Robert
Publisher: name: The Open University
Year: 2005

description: Additive synthesis is a fundamental computer music synthesis paradigm tracing its origins to the work of Fourier and Helmholtz. Rudimentary implementation linearly combines harmonic sinusoids (or partials) to generate tones whose perceived timbral characteristics are a strong function of the partial amplitude spectrum. Having evolved over time, additive synthesis describes a collection of algorithms each characterised by the time-varying linear combination of basis components to generate temporal evolution of timbre. Basis components include exactly harmonic partials, inharmonic partials with time-varying frequency or non-sinusoidal waveforms each with distinct spectral characteristics. Additive synthesis of polyphonic musical instrument tones requires a large number of independently controlled partials incurring a large computational overhead whose investigation and reduction is a key motivator for this work.

The thesis begins with a review of prevalent synthesis techniques setting additive synthesis in context and introducing the spectrum modelling paradigm which provides baseline spectral data to the additive synthesis process obtained from the analysis of natural sounds. We proceed to investigate recursive and phase accumulating digital sinusoidal oscillator algorithms, defining specific metrics to quantify relative performance. The concepts of phase accumulation, table lookup phase-amplitude mapping and interpolated fractional addressing are introduced and developed and shown to underpin an additive synthesis subclass - wavetable lookup synthesis (WLS). WLS performance is simulated against specific metrics and parameter conditions peculiar to computer music requirements. We conclude by presenting processing architectures which accelerate computational throughput of specific WLS operations and the sinusoidal additive synthesis model. In particular, we introduce and investigate the concept of phase domain processing and present several “pipeline friendly” arithmetic architectures using this technique which implement the additive synthesis of sinusoidal partials.

description: In a photoionization spectrum in which there is no excitation of the discrete states, but only the underlying continuum, we have observed resonances which appear as symmetric peaks, not the commonly expected window resonances. Furthermore, since the excitation to the unperturbed continuum vanishes, the cross section expected from Fano's configuration interaction theory is identically zero. This shortcoming is removed by the explicit introduction of the phase shifted continuum, which demonstrates that the shape of a resonance, by itself, provides no information about the relative excitation amplitudes to the discrete state and the continuum.

description: Zircon is the most frequently used mineral for dating terrestrial and extraterrestrial rocks. However, the system of zircon in mafic/ultramafic melts has been rarely explored experimentally and most existing models based on the felsic, intermediate and/or synthetic systems are probably not applicable for prediction of zircon survival in terrestrial shallow asthenosphere. In order to determine the zircon stability in such natural systems, we have performed high-temperature experiments of zircon dissolution in natural mid-ocean ridge basaltic and synthetic haplobasaltic melts coupled with in situ electron probe microanalyses of the experimental products at high current. Taking into account the secondary fluorescence effect in zircon glass pairs during electron microprobe analysis, we have calculated zirconium diffusion coefficient necessary to predict zircon survival in asthenospheric melts of tholeiitic basalt composition. The data imply that typical 100 micron zircons dissolve rapidly (in 10 hours) and congruently upon the reaction with basaltic melt at mantle pressures. We observed incongruent (to crystal ZrO2 and SiO2 in melt) dissolution of zircon in natural mid-ocean ridge basaltic melt at low pressures and in haplobasaltic melt at elevated pressure. Our experimental data raise questions about the origin of zircons in mafic and ultramafic rocks, in particular, in shallow oceanic asthenosphere and deep lithosphere, as well as the meaning of the zircon-based ages estimated from the composition of these minerals. Large size zircon megacrysts in kimberlites, peridotites, alkali basalts and other magmas suggest the fast transport and short interaction between zircon and melt.The origin of zircon megacrysts is likely related to metasomatic addition of Zr into mantle as any mantle melting episode should obliterate them.

description: Dynamic and precise measurement of cerebral blood flow velocity is crucial in neuroscience and the diagnosis of cerebrovascular diseases. Traditional color Doppler ultrasound can only measure the velocity component along the ultrasound beam, which restricts its ability to accurately capture the complete blood flow vector in complex environments. To overcome these limitations, we propose an ultrafast pulse-coded vector Doppler (PC-UVD) imaging method, utilizing Hadamard matrix-based pulse encoding to improve velocity estimation accuracy under low signal-to-noise ratio (SNR) conditions. Our study encompasses spiral flow simulations and in vivo rat brain experiments, showing significantly enhanced measurement precision compared to conventional ultrafast vector Doppler (UVD). This innovative approach enables the measurement of dynamic cerebral blood flow velocity within a single cardiac cycle, offering insights into the characteristics of cerebrovascular resistivity. The proposed PC-UVD method employs Hadamard matrix encoding of plane waves, boosting SNR without compromising temporal or spatial resolution. Velocity vectors are subsequently estimated using a weighted least squares (WLS) approach, with iterative residual-based weight optimization improving robustness to noise and minimizing the impact of outliers. The effectiveness of this technique is confirmed through simulations with a spiral blood flow phantom, demonstrating a marked improvement in velocity estimation accuracy, particularly in deep imaging regions with significant signal attenuation. In vivo experiments on rat brains further confirm that the proposed method offers greater accuracy than existing UVD approaches, particularly for small vessels. Notably, our method can precisely differentiate arterial from venous flow by analyzing pulsatility and resistivity within the cerebral vascular network.

title: The Role of Viral Load in the Pathogenesis of HIV-2 Infection in West Africa
Creators: name: Ariyoshi, Koya
Publisher: name: The Open University
Year: 1998

description: The role of Human Immunodeficiency Virus type 2 (HTV-2) viral load has been studied in West Africa in order to understand how this infection differs from HIV-1 and why the majority of HIV-2 infected individuals live for long.

 Using a polymerase chain reaction (PCR) based-assay, it was found that the level of HIV-2 provirus was surprisingly high in HTV-2 seropositive people who live long without sign of immunosuppression; in contrast the rate of HIV-2 replication reflected by RNA viral load was found low. However, HIV-2 replicates to a high titre in some HIV-2-infected people whose disease progresses rapidly to death. Longitudinal follow-up demonstrated that baseline HIV-2 RNA viral load predicts the rate of CD4+ T cell decline and death but the level of proviruses is a less sensitive predictor.

 Cytotoxic T-lymphocyte activity (CTL) against HIV-2 structural proteins, especially Gag, was found in most HIV-2 infected people and was inversely correlated with HIV-2 proviral load. Strong CTL activity was consistently found in people who did not have progressive disease, suggesting that CTL play an important role in controlling HIV-2 replication.

 Co-infection with human T-lymphotropic virus type I (HTLV-I) occurred frequently in HIV-2-infected people in a village in Guinea-Bissau but did not seem to enhance HIV-2 viral load. However an increase in HIV-2 viral load was found in an HIV-2-infected individual with malaria parasitaemia, suggesting that malaria infection enhances HIV-2 viral load.

 The majority of people who are dually seroreactive for both HIV-1 and HIV-2 arc infected with both viruses but some subjects are dually seroreactive because antibodies against one type cross-react with the other type of HIV. These cross-reactive antibodies may be distinguished by antibody dilution analysis. Other dually seroreactive people harbour an undetectable level of HIV-2 provirus and HIV-2 proviral load tended to be low in advanced disease while HIV-1 proviral load was high.

description: Bushes of normal modes represent the exact excitations in nonlinear physical systems with discrete symmetries [Physica D117 (1998) 43]. The present paper is the continuation of our previous paper [Physica D166 (2002) 208], where these dynamical objects of a new type were discussed for the monoatomic nonlinear chains. Here, we develop a simple crystallographic method for finding bushes in nonlinear chains and investigate stability of one-dimensional and two-dimensional vibrational bushes for both FPU-alpha and FPU-beta models, in particular, of those revealed recently in [Physica D175 (2003) 31].

description: An accurate study of the lowest $1σ_g$ and the low-lying excited $1σ_u$, $1π_{u,g}$, $1δ_{g,u}$ electronic states of the exotic molecular ion $H_3^{2+}$ in linear configuration parallel to a magnetic field is carried out. The magnetic field ranges from $10^{10}$ G up to $4.414 \times 10^{13}$ G where non-relativistic considerations are justified. The variational method is exploited and the {\it same} trial function is used for different magnetic fields. It is shown that the states of positive $z$-parity $1σ_g, 1π_u, 1δ_{g}$ are bound states of the $H_3^{2+}$ exotic ion for all magnetic fields studied. We also demonstrate that for magnetic fields $B\gtrsim 2.35\times 10^{12}$ G the potential energy surface well corresponding to the $1σ_g$ state contains at least one longitudinal vibrational state. It is also shown that the negative $z$-parity states $1σ_u, 1π_g, 1δ_{u}$, are purely repulsive in the whole range of magnetic fields studied, $B=10^{10}- 4.414 \times 10^{13}$ G.

SL(2,R)/U(1) Supercoset and Elliptic Genera of Non-compact Calabi-Yau Manifolds

description: We first discuss the relationship between the SL(2;R)/U(1) supercoset and N=2 Liouville theory and make a precise correspondence between their representations. We shall show that the discrete unitary representations of SL(2;R)/U(1) theory correspond exactly to those massless representations of N=2 Liouville theory which are closed under modular transformations and studied in our previous work hep-th/0311141. It is known that toroidal partition functions of SL(2;R)/U(1) theory (2D Black Hole) contain two parts, continuous and discrete representations. The contribution of continuous representations is proportional to the space-time volume and is divergent in the infinite-volume limit while the part of discrete representations is volume-independent. In order to see clearly the contribution of discrete representations we consider elliptic genus which projects out the contributions of continuous representations: making use of the SL(2;R)/U(1), we compute elliptic genera for various non-compact space-times such as the conifold, ALE spaces, Calabi-Yau 3-folds with A_n singularities etc. We find that these elliptic genera in general have a complex modular property and are not Jacobi forms as opposed to the cases of compact Calabi-Yau manifolds.

description: We study light absorption in many-electron interacting systems beyond the linear regime by using a {\em single} broadband impulse of an electric field in the instantaneous limit. We determine non-pertubatively the absorption cross section from the Fourier transform of the time-dependent induced dipole moment, which can be obtained from the time evolution of the wavefunction. We discuss the dependence of the resulting cross section on the magnitude of the impulse and we highlight the advantages of this method in comparison with perturbation theory working on a one-dimensional model system for which numerically exact solutions are accessible. Thus we demonstrate that the considered non pertubative approach provides us with an effective tool for investigating fluence-dependent nonlinear optical excitations.

description: Polar optical phonons are studied in the framework of the dielectric continuum approach for a prototypical quantum-dot/quantum-well (QD/QW) heterostructure, including the derivation of the electron-phonon interaction Hamiltonian and a discussion of the effects of this interaction on the electronic energy levels. The particular example of the CdS/HgS QD/QW is addressed and the system is modelled according to the spherical geometry, considering a core sphere of material "1" surrounded by a spherically concentric layer of material "2", while the whole structure is embedded in a host matrix assumed as an infinite dielectric medium. The strength of the electron-LO phonon coupling is discussed in details and the polaronic corrections to both ground state and excited state electron energy levels are calculated. Interesting results concerning the dependence of polaronic corrections with the QD/QW structure size are analyzed.
