description: The human civilization is faced with a formidable task to feed, house and ensure a healthy lifestyle for the continuous expanding human population, all the while protecting the environment and natural resources for the benefit of coming future generations. Food-borne zoonotic infections are the primary global cause of disease in humans and they are particularly prevalent in underdeveloped nations where they inflict significant economic losses in addition to public health problems. Salmonella species, E. coli, L. monocytogenes, S. aureus, and Campylobacter species are the world's most common zoonotic bacterial infections, responsible for foodborne illnesses and deaths linked to the consumption of tainted animal products. Food safety management systems provide a better option to produce safe food for human consumption.

Competing Risks

Cause-specific Hazard

description: We compare two multi-state modelling frameworks that can be used to represent dates of events following hospital admission for people infected during an epidemic. The methods are applied to data from people admitted to hospital with COVID-19, to estimate the probability of admission to intensive care unit, the probability of death in hospital for patients before and after intensive care unit admission, the lengths of stay in hospital, and how all these vary with age and gender. One modelling framework is based on defining transition-specific hazard functions for competing risks. A less commonly used framework defines partially-latent subpopulations who will experience each subsequent event, and uses a mixture model to estimate the probability that an individual will experience each event, and the distribution of the time to the event given that it occurs. We compare the advantages and disadvantages of these two frameworks, in the context of the COVID-19 example. The issues include the interpretation of the model parameters, the computational efficiency of estimating the quantities of interest, implementation in software and assessing goodness of fit. In the example, we find that some groups appear to be at very low risk of some events, in particular intensive care unit admission, and these are best represented by using 'cure-rate' models to define transition-specific hazards. We provide general-purpose software to implement all the models we describe in the flexsurv R package, which allows arbitrarily flexible distributions to be used to represent the cause-specific hazards or times to events.

description: This document collates, in the form of an annotated bibliography, a wide range of published works (e.g. reports, academic publications, guidebooks and manuals, blogs) that are relevant to assessing the performance and impact of research infrastructures. Key ELIXIR-relevant publications are starred ⭐. This is the first public-facing version of an otherwise internal document, never meant to be exhaustive, yet very likely to be useful to others outside of ELIXIR. The primary audiences for this document are hence those wishing to understand, demonstrate and communicate the performance, impact, and ultimately public value of the research infrastructure they fund, host, create, operate and manage. The annotated bibliography is organised in six main sections: (1) Works relating to named research infrastructures, (2) Project outputs related to/involving research infrastructures, (3) Academic publications, (4) Impact evaluation manuals, (5) Other relevant publications, and (6) Blog articles. The authors warmly welcome suggestions for new entries to the bibliography.

description: The original WAIS implementation by Thinking Machines et al. treats documents as uniform bags of erms. Since most documents exhibit some internal structure, it is desirable to provide the user means to exploit this structure in his queries. In this paper, we present extensions to the [freeWAIS][1] indexer and server, which allow access to documents structure using the original WAIS protocol. Major extensions include: arbitrary document formats, search in individual structure elements, stemming and phonetic search, support of 8-bit character sets, numeric concepts and operators, combination of Boolean and linear retrieval. We also present an WWW-WAIS gateway specially tailored for usage with [freeWAIS-sf], which transforms filled out HTML forms to the new query syntax.
The erosion of ductile metals by solid particles
Creators: name: Hutchings, IM
Publisher: name: Apollo - University of Cambridge Repository
Year: 1974

description: Erosion is a wear process, in which surface damage is caused by the repeated application of high localised stresses. Erosion by solid particle impact is a problem of great practical significance which can result in component failures in, for example, turbines and energy conversion systems. This dissertation describes experiments in which ductile metal surfaces were eroded with abrasive particles (size range 40 - 600nm) under controlled conditions. Damage to the surface was characterised by weight loss measurements, and also by microscopical examination. Surface and subsurface damage was studied using optical microscopy and also scanning electron microscopy. As a result of this experimental work a new model of the erosion process, for ductile metals eroded by spherical particles at normal impingement, is proposed. Analytical techniques were used to investigate the observed surface deformations, and also the energy requirements of the proposed model. Further experiments were conducted to investigate the effect of erodent particle shape on the erosion of mild steel. A literature survey was completed, which identifies methods which may prove useful in quantifying the shapes of abrasive particles. A study of the effect of nitrogen ion implantation on the erosion resistance of mild steel was completed. An investigation of indentation parameters provided an explanation for the minimal effects recorded. The technique of cross correlation has been applied to. the problem of measuring the velocity of the erodent particles. A device has been developed to measure the time of flight of particles over a known djstance . Data from this device was analysed on a micro-computer.

description: IceCube is as neutrino telescope deposited in the glacial ice at the geographic south pole with an instrumented volume of one cubic kilometer. This work presents results on the energy unfolding of muon neutrinos with the IceCube Neutrino Observatory in its 86 string configuration. For the unfolding a sample of high quality muon neutrinos with a purity above 99.2% using a random forest was derived. The unfolding was performed using a second derivative Tikhonov regularization within the software TRUEE. The unfolding covers an energy range of more than 4 decades starting at 125 GeV and ending at 3.2 PeV.

description: Background Information: Studies of Antiretroviral Therapy program in Africa have shown high incidence rate of tuberculosis in both Antiretroviral Therapy receiving and Antiretroviral Therapy naïve Human Immunodeficiency Virus infected patients. Tuberculosis incidence and factors that contribute for development of tuberculosis in era of Antiretroviral Therapy were poorly described in Ethiopia. Objective: To examine the effect of HAART on incidence rate of tuberculosis and tuberculosis free survival among HIV-positive adults in HAART receiving and HAART naïve groups enrolled to ART clinic in Hawassa University Referral Hospital. Method: A retrospective cohort study design was used on 632 HIV-positive adults with age 15 years old and above enrolled to ART clinic in Hawassa University Referral Hospital over a three-year period. Incidence rate of tuberculosis and TB free survival was calculated and compared for Pre-HAART and HAART follow up HIV/AIDS patients. In this study, patients who followed on Pre-HAART are considered as unexposed and patients who receiving HAART considered as exposed, and was followed for three years from July 2006 to January 2011. Result: A total of 632 patients (316 in ART and 316 in ART cohort) followed for a median of 32.9(IQR=17.6-36.5) months in Pre-HAART and 35.4 (IQR=23.6-36.5) months in HAART cohort. TB incidence rate was 3.5 and 7.2 per 100 PYO in HAART and Pre-HAART cohort respectively. Over all chance of not developing TB was high in HAART cohort (Log rank=8.24, df=1, P=0.004). Being on HAART (AHR=0.182, 95%CI=0.078-0.424, P<0.001), being married (AHR=0.354 95%CI=0.191-0.655, P=0.001) and widowed (AHR=0.375, 95%CI=0.169-0.831, P=0.016) were factors related to decreased TB incidence. WHO stage 3 or 4 (AHR=1.999, 95%CI=1.025-3.896, P=0.042), being bedridden (AHR=4.689, 95%CI=1.715-12.819, P=0.003), and having hemoglobin level less than 10mg/dl (AHR=2.497, 95%CI=1.098-5.679, P=0.036) were factors associated with increased risk of TB at multivariate analysis. Conclusion: HAART decreased new cases of tuberculosis by 81.8% compared to HAART naïve patients and the probability of not developing TB was higher in HAART cohort than Pre- HAART. The finding is similar level with other developing and developed countries, but still gross TB incidence rate was high in both Pre-HAART and HAART cohort when compared with developed countries. More efforts have to be taken to reduce TB incidence as level of most developed countries have achieved many years ago
Assessment of Factors Associated With Perinatal Mortality among Public Hospital Deliveries in Addis Ababa, Ethiopia
Creators: name: Getiye, Yemisrach
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Back ground of the study: Perinatal mortality is a death of fetuses weighing at least 1000gm or 28weeks of gestation or more if weight is not available and death of live newborn before the age of 7 days. It makes three fourth of the deaths of the neonatal period and widely used as a health indicator for newborn care and reflects prenatal, intra partum and newborn care. Objective: To assess factors associated with perinatal mortality among hospital deliveries in selected hospitals of Addis Ababa, Ethiopia. Methods: An unmatched case control study using secondary data as a source of information was conducted. A total 1113 samples (376 cases and 737 controls) were recruited from four public hospitals of Addis Ababa. Cases were still births and early neonatal deaths and controls were live births and neonates who were discharged alive from the hospital and did not die before the age of 7 days. The study period was from January 1st up to February 30/ 2015. Epi-Info version 7.0 and SPSS Version 21 were used for data entry and analysis respectively. Descriptive statistics using measure of central tendency and dispersion, frequencies, proportions and diagrams was used to check its distribution and describe the study population in relation to relevant variables. Logistic regression model was used to identify the important factors that are associated with perinatal mortality Results: The mean age of the mothers for cases and controls were 26.47+4.87 and 26.95+4.68 respectively. Five hundred ninety seven (53.6%) mothers delivered for the first time. Obstetric complication occurred in 64.4% of cases and 43.8% of controls. Factor that are significantly associated with increased risk of perinatal death were birth interval less than 2 years (AOR=4.55; 95%CI(1.79-11.54), preterm delivery (AOR=4.55;95%CI(1.79-11.54)), anemia(AOR= 2.6;95%CI(1.38-4.91) and the others were congenital anomaly, previous history of early neonatal death and low birth weight).Use of partograph was another factor that is associated with decreased risk of perinatal mortality (AOR=0.35; 95%CI (0.18-0.66)). Conclusion & recommendation: From factors that are associated with perinatal death, some of them can be prevented with early investigation of pregnant mothers up on their follow up to identify abnormalities and manage them accordingly. In addition, appropriate labor follow up and monitoring with regular use of partograph, immediate newborn care and interventions to delay birth interval should be addressed
Search for pair-production of vector-like quarks in $pp$ collision events at $\sqrt{s}=13$ TeV with at least one leptonically decaying $Z$ boson and a third-generation quark with the ATLAS detector

description: A search for the pair-production of vector-like quarks optimized for decays into a $Z$ boson and a third-generation Standard Model quark is presented, using the full Run 2 dataset corresponding to 139 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=13$ TeV, collected in 2015-2018 with the ATLAS detector at the Large Hadron Collider. The targeted final state is characterized by the presence of a $Z$ boson with high transverse momentum, reconstructed from a pair of same-flavour leptons with opposite-sign charges, as well as by the presence of $b$-tagged jets and high-transverse-momentum large-radius jets reconstructed from calibrated smaller-radius jets. Events with exactly two or at least three leptons are used, which are further categorized by the presence of boosted $W$, $Z$, and Higgs bosons and top quarks. The categorization is performed using a neural-network-based boosted object tagger to enhance the sensitivity to signal relative to the background. No significant excess above the background expectation is observed and exclusion limits at 95% confidence level are set on the masses of the vector-like partners $T$ and $B$ of the top and bottom quarks, respectively. In the singlet model, the limits allow $m_T > 1.27$ TeV and $m_B > 1.20$ TeV. In the doublet model, allowed masses are $m_T > 1.46$ TeV and $m_B >1.32$ TeV. In the case of 100% branching ratio for $T\rightarrow Zt$ and 100% branching ratio for $B\rightarrow Zb$, the limits allow $m_T > 1.60$ TeV and $m_B > 1.42$ TeV, respectively.

description: Ties between individuals on a social network can represent different dimensions of interactions, and the spreading of information and innovations on these networks could potentially be driven by some dimensions more than by others. In this paper we investigate this issue by studying the diffusion of microfinance within rural India villages and accounting for the whole multilayer structure of the underlying social networks. We define a new measure of node centrality, diffusion versatility, and show that this is a better predictor of microfinance participation rate than previously introduced measures defined on aggregated single-layer social networks. Moreover, we untangle the role played by each social dimension and find that the most prominent role is played by the nodes that are central on layers concerned with trust, shedding new light on the key triggers of the diffusion of microfinance.

description: Standard Model extensions with a strongly coupled dark sector can induce high-multiplicity states of soft quarks. Such final states trigger extremely efficient antinucleus formation. We show that dark matter annihilation or decay into a strongly coupled sector can dramatically enhance the cosmic-ray antinuclei flux -- by six orders of magnitude in the case of ${^4\overline{\text{He}}}$. In this work, we argue that the tentative ${^3\overline{\text{He}}}$ and ${^4\overline{\text{He}}}$ events reported by the AMS-02 collaboration could be the first sign of a strongly coupled dark sector observed in nature.

description: A large fraction of gamma-ray bursts (GRBs) shows a plateau phase during the X-ray afterglow emission, whose physical origin is still debated. In this work we define a sample of 30 GRBs with simultaneous X-ray and optical data during and after the plateau phase. Through a time-resolved spectral analysis of the X-ray plateaus, we test the consistency of the unabsorbed optical fluxes with those obtained via X-ray-to-optical spectral extrapolation by assuming a synchrotron spectrum. Combining X-ray with optical data, we find that 63% (19/30) GRBs are compatible with a single synchrotron spectrum thus suggesting that both the optical and X-ray radiations are produced from a single emitting region. For these GRBs we derive the temporal evolution of the break frequency and we compare it with the expectations predicted by several models. For 11/30 GRBs the optical emission is above the predicted range of values extrapolated from the X-rays in at least one temporal bin of the light curve. These GRBs may not be explained with a single zone emission, indicating the necessity of invoking two cooperating processes in order to explain the broad band spectral behaviour during X-ray plateaus. We discuss our findings in the framework of different scenarios invoked to explain the plateau feature, including the energy injection from a spinning-down magnetar and the high latitude emission from a structured jet.

description: Citric acid introduced into the stomach of mice at increasing concentrations of 0.1, 1 or 10 % (4.8 µM-0.48 mM; 95 µmol/kg-9.5 mmol/kg, 0.5 ml) caused dose-dependent inhibition of abdominal constrictions induced 1 h later by i. p. acetic acid injection by -51 % to -69.5 %. When administered at 10 % (0.48 mM, 0.5 ml) 15 min before nociceptive challenge, citric acid inhibited the nociceptive response by 96.8 %. Inhibition of the acetic acid-induced abdominal constrictions was also observed when lower doses of citric acid were introduced into the stomach (0.2 ml of 0.1-1 %; 38.1 µmol/kg-0.38 mmol/kg). The effect was evident as early as 5 min after administration of citric acid into the stomach and with the maximal effect being at 15-30 min after dosing. Lidocaine given orally 5 min prior to citric acid (1 %, 48 µM; 0.38 mmol/kg, 0.2 ml) prevented antinociception by citric acid, but lidocaine given 15 min before oral introduction of citric acid enhanced the citric acid-induced inhibition of the nociceptive response to acetic acid. The antinociceptive effect of orally administered citric acid (1 %, 48 µM; 0.38 mmol/kg, 0.2 ml) was increased by pre-treatment with propranolol (4 mg/kg, s. c.), yohimbine (4 mg/kg, s. c.), guanethidine (32 mg/kg, s. c.), but reduced after treatment with atropine (3 mg/kg, s. c.), which itself increased the nociceptive behavior. Similar inhibition of the acetic acid-induced nociceptive behavior was also observed when sodium citrate (pH 7.21) or 0.1 N HCl (pH 3) or 1 % sucrose solution (0.2 ml) was intragastrically given. It is suggested that citric acid might act to stimulate sensory afferents and that transmission of nociceptive information centrally leads to the activation of descending antinociceptive mechanism to a noxious stimulus.

description: A novel hydraulic fracture (HF) formulation is introduced which accounts for the hydraulically induced shear stress at the crack faces. It utilizes a general form of the elasticity operator alongside a revised fracture propagation condition based on the critical value of the energy release rate. It is shown that the revised formulation describes the underlying physics of HF in a more accurate way and is in agreement with the asymptotic behaviour of the linear elastic fracture mechanics. A number of numerical simulations by means of the universal HF algorithm previously developed in Wrobel & Mishuris (2015) are performed in order to: i) compare the modified HF formulation with its classic counterpart and ii) investigate the peculiarities of the former. Computational advantages of the revised HF model are demonstrated. Asymptotic estimations of the main solution elements are provided for the cases of small and large toughness. The modified formulation opens new ways to analyse the physical phenomenon of HF and also improves the reliability and efficiency of its numerical simulations.

description: Planet(s) in binaries are unique architectures for testing predictions of planetary formation and evolution theories in very hostile environments. We used the IRDIS dual-band imager of SPHERE at VLT, and the speckle interferometric camera HRCAM of SOAR, to acquire high-angular resolution images of HD 196885 AB between 2015 and 2020. Radial velocity observations have been extended over almost 40 yr extending the radial velocity measurements HD 196885 A and resolving both the binary companion and the inner giant planet HD 196885 Ab. Finally, we took advantage of the exquisite astrometric precision of the dual-field mode of VLTI/GRAVITY (down to 30 μas) to monitor the relative position of HD 196885 A and B to search for the 3.6 yr astrometric wobble of the circumprimary planet Ab imprinted on the binary separation. Our observations enable to accurately constrain the orbital properties of the binary HD 196885 AB, seen on an inclined and retrograde orbit (iAB = 120.43 deg) with a semi-major axis of 19.78 au, and an eccentricity of 0.417. The GRAVITY measurements confirm for the first time the nature of the inner planet HD 196885 Ab by rejecting all families of pole-on solutions in the stellar or brown dwarf masses. The most favored island of solutions is associated with a Jupiter-like planet (MAb = 3.39 MJup), with moderate eccentricity (eAaAb = 0.44), and inclination close to 143.04 deg. This results points toward a significant mutual inclination (Phi = 24.36 deg) between the orbital planes (relative to the star) of the binary companion B and the planet Ab. Our dynamical simulations indicate that the system is dynamically stable over time. Eccentricity and mutual inclination variations could be expected for moderate von Zipele Kozai Lidov cycles that may affect the inner planet.

description: Superconductivity in one-atom-layer iron selenide (FeSe) on a strontium titanate (STO) substrate is enhanced by almost an order of magnitude with respect to bulk FeSe. There is recent experimental evidence suggesting that this enhancement persists in FeSe/STO nano-islands. More specifically, for sizes $L \sim 10$ nm, the superconducting gap is a highly non-monotonic function of $L$ with peaks well above the bulk gap value. This is the expected behavior only for weakly-coupled metallic superconductors such as Al or Sn. Here we develop a theoretical formalism to describe these experiments based on three ingredients: Eliashberg theory of superconductivity in the weak coupling limit, pairing dominated by forward scattering and periodic orbit theory to model spectral fluctuations. We obtain an explicit analytical expression for the size dependence of the gap that describes quantitatively the experimental results with no free parameters. This is a strong suggestion that superconductivity in FeSe/STO is mediated by STO phonons. We propose that, since FeSe/STO is still a weakly coupled superconductor, quantum size effects can be used to further enhance the bulk critical temperature in this interface.

description: Background: Globally depression among women is a public health problem. Postpartumdepression is a depressive symptoms and syndromes that happen within the first year after birth. Postpartum depression is more commonly diagnosed among adolescents and it is risk factor forpoor growth and development in children born to these mothers. Objective: The study aims to assess the magnitude of postpartum depression and its associated factors among postpartum adolescent mothers attending at health facilities in Bench Maji Zonein Ethiopia. Method: Facility based cross sectional study was deployed among postpartum adolescentmothers between February - April 2019. Multi-stage sampling technique was used to select 407women and a structured questionnaire through face to face interview was used to collect the data. Postpartum depression was measured using the Edinburgh postnatal depression scale. Data wereentered in to Epi-data 4.4.2.1 and analyzed using SPSS version software 23.Descriptive statisticswere computed to reveal the magnitude. Variables which are associated significantly (P-value 0.05) in Binary logistic regression model were taken to the multivariable regression model.Strength association measured through OR and its 95% CI statistical significance was declared atP-value <0.05. Result: Among the study participants, 80 (19.6%) of them had postpartum depression .Thoserespondents who had Low social support (AOR=4.7(95% C.I: 2.02-11.08), previous history ofpostpartum depression (AOR=3.7 (95% C.I: 1.7-7.9), who had low income (AOR=2.2 (95% C.I: 1.19, 4.2) and unplanned pregnancy(AOR=2 (95% C.I: 1.05-3.4) were found to significantincrease odd of postpartum depression among adolescent. Those adolescent postpartum women'swho had spontaneous delivery [AOR=0.37(95% C.I: 0.14-0.70) less likely to have postpartum depression. Conclusion: The magnitude of postpartum depression was 19.6% among adolescent women.Furthermore, income, unplanned pregnancy, previous history of depression and social supportwere found to be independent predictors for the development of postpartum depression among adolescent women. Therefore, provide proper counseling and emotional support for vulnerable postpartum mothers; promote utilization of FP to reduce unwanted pregnancy.

description: Zeta Aquarii is a bright and nearby (28 pc) triple star with a 26-year astrometric subsystem. Almost a half of the outer 540-year visual orbit has been covered in 238 years of its observations. Both inner and outer orbits are revised here taking into account recent direct resolution of the inner pair Aa,Ab. The inner orbit has a high eccentricity of 0.87 and is inclined to the outer orbit by 140+-10 degrees, suggesting that Kozai-Lidov cycles take place. The masses of the stars Aa, B, and Ab are 1.4, 1.4, and 0.6 solar. The age of the system is about 3 Gyr, and the two main components have just left the main sequence. Hypothetically, this system could have formed by a dynamical capture of the small star Ab in the twin binary Aa,B.

description: Θέμα της παρούσας μεταπτυχιακής εργασίας είναι η μεταφορά ελληνικών έργων τέχνης στην Ρώμη στην Ελληνιστική και Ρεπουμπλικανική περίοδο, μέσα από την μαρτυρία των ναυαγίων. Αρχικά, παρουσιάστηκε η επέκταση του Ρωμαϊκού κράτους στην Ανατολή και οι επιρροές που δέχτηκαν από τους κατεκτημένους λαούς, καθώς και το εμπόριο έργων τέχνης την περίοδο αυτή. Στην συνέχεια εξετάστηκαν έξι ναυάγια που χρονολογούνται από τα μέσα του 2ου αι έως και τα μέσα του 1ου αι π.Χ., και τα αγάλματα από το λιμάνι του Πειραιά. Τα πλοία αυτά μετέφεραν έργα με τελικό προορισμό την Ρώμη, με σκοπό να καλύψουν τις αισθητικές ανάγκες της ρωμαϊκής αριστοκρατίας. Παράλληλα, προσφέρουν χρήσιμες πληροφορίες για τα αντικείμενα πολυτελείας που μεταφέρονταν την περίοδο αυτή και τις αισθητικές τάσεις που επικρατούσαν την περίοδο
description: The subject of the present Master Thesis is the study of the transportation of Greek artwork to Rome during the Hellenistic and Republican period, based on the testimony of shipwrecks. Firstly, we examined the expansion of the Roman state to the Hellenistic world, the influences it received from the occupied territories, as well as the commerce of artwork. Then, we examined six shipwrecks, dated from the middle of the 2nd century until the middle of the 1st century B.C. as well as the statues from the port of Piraeus. Those ships carried works of art to Rome to satisfy the artistic needs of the Roman aristocracy. At the same time, the transported commodities offer a unique insight into the popularity and circulation of luxurious objects during that period

description: We briefly discuss the most prominent results and specific sources detected by gravitational-wave observatories LIGO-Virgo during first three O1-O3 runs, as well as possible astrophysical and cosmological channels of their formation. We show that it is possible to explain the observed correlation between the effective spin of coalescing binary black holes and mass ratio of the components by accretion from the ambient medium onto primordial binary black holes. We also briefly discuss the recent results of searches for stochastic gravitational-wave background in the nano-Hz frequency band by pulsar timing arrays.

description: Applications of nanotechnology have increased the importance of research and nanocarriers, which have revolutionized the method of drug delivery to treat several diseases, including cancer, in the past few years. Cancer, one of the world’s fatal diseases, has drawn scientists’ attention for its multidrug resistance to various chemotherapeutic drugs. To minimize the side effects of chemotherapeutic agents on healthy cells and to develop technological advancement in drug delivery systems, scientists have developed an alternative approach to delivering chemotherapeutic drugs at the targeted site by integrating it inside the nanocarriers like synthetic polymers, nanotubes, micelles, dendrimers, magnetic nanoparticles, quantum dots (QDs), lipid nanoparticles, nano-biopolymeric substances, etc., which has shown promising results in both preclinical and clinical trials of cancer management. Besides that, nanocarriers, especially biopolymeric nanoparticles, have received much attention from researchers due to their cost-effectiveness, biodegradability, treatment efficacy, and ability to target drug delivery by crossing the blood−brain barrier. This review emphasizes the fabrication processes, the therapeutic and theragnostic applications, and the importance of different biopolymeric nanocarriers in targeting cancer both in vitro and in vivo, which conclude with the challenges and opportunities of future exploration using biopolymeric nanocarriers in onco-therapy with improved availability and reduced toxicity

description: Als bedeutsamste Vorhersagekriterien für spätere Lese-Rechtschreibleistungen haben sich metalinguistische Fähigkeiten (phonologische Bewußtheit, phonologisches Recodieren beim Zugriff auf das sementische Lexikon, phonetisches Recodieren im Arbeitsgedächtnis) erwiesen. Darüber hinaus sind zeitliche Verarbeitungsmechanismen im Zehntel- Millisekundenbereich für die Sprachperzeption und -verarbeitung von erheblicher Bedeutung. Es wird angenommen, daß Beeinträchtigungen basaler zeitlicher Verarbeitungsmechanismen (auditive Ordnungsschwelle) zu Defiziten in der Entwicklung phonologischer Bewußtheit und damit auch zu Lese-Rechtschreibstörungen führen. In einer empirischen Untersuchung wurde der Frage nachgegangen, welche Zusammenhänge zwischen zeitlicher Verarbeitungsfähigkeit, phonologischer Bewußtheit, phonetischem Recodieren im Arbeitsgedächtnis, nonverbaler Intelligenz, Rhythmuserfassen und früher Lesefertigkeit bestehen. Darüber hinaus wurden in einer längsschnittlichen Betrachtung diese Variablen im Hinblick auf ihre Bedeutung für die Lese-Rechtschreibleistungen am Ende des 1. Schuljahres analysiert. Die Stichprobe bestand aus 3 Gruppen (Frühleser, "normale" Grundschulkinder, sprachbehinderte Kinder) und umfaßte 147 Schulanfänger. Es zeigten sich signifikante Gruppenunterschiede in der zeitlichen Verarbeitungsfähigkeit, der phonologischen Bewußtheit, der nonverbalen Intelligenz, im Rhythmuserfassen sowie im Arbeitsgedächtnis. Ferner ließen sich signifikante Korrelationen zwischen zeitlicher Verarbeitungsfähigkeit und phonologischer Bewußtheit ermitteln. Dagegen konnten keine signifikanten Korrelationen zwischen zeitlichen Verarbeitungsprozessen und Lese-Rechtschreibleistungen nachgewiesen werden. Lediglich 28% der rechtschreibschwachen Kinder hatten auffällige Ordnungsschwellenwerte. Sehr signifikante Korrelationen zeigten sich hingegen zwischen phonologischer Bewußtheit und Lese-Rechtschreibleistungen. Die Untersuchung belegt die Annahme eines Zusammenhangs zwischen zeitlichen Verarbeitungsprozessen und phonologischer Bewußtheit. Von einem einfachen monokausalen Zusammenhang zwischen zeitlicher Verarbeitungsfähigkeit und Lese-Rechtschreibleistungen kann dagegen nicht ausgegangen werden.

description: Back ground: Access to healthfully housing, improved water supply, sanitation and hygienic practices in general and urban sanitation in particular is one of the major issues in public health protection and survival of human being. The ever increasing unplanned urbanization and poor access to safe water supply, sanitation and unhealthful living and working environment leads to tremendous communicable & none communicable diseases. Objective of the study: The general objective of the study was to assess environmental health status of Dukam town and generate relevant information for informed decision making process of town officials and concerned stakeholders. Methods: A community based cross-sectional study was conducted in Dukam town from March to May, 2010. Using systematic random sampling methods a total of 409 households were selected for quantitative information while physical observation was made to see sanitary status of municipal water system, solid and liquid waste management and housing condition of the town. Quantitative data collected using pretested and standardized questionnaire was entered using EPI-Info version 6.04 and exported to SPSS 16.0 window version for cleaning and analysis. Frequencies, proportions and summary statistics were employed to describe the study population in relation to the objective of the study. Logistic regression analysis was also employed to examine association among major dependent and independent variables. Result: The findings of this study revealed that over all access to healthful- housing, improved water sources, latrine facility and appropriate solid and liquid waste management system were found very low and significantly associated to educational status, income and ownership of the households. Conclusions and Recommendations: Given that Dukam is currently expanding, considerable portion of inhabitants are currently living in poor housing condition and out of access to safe and adequate water supply, improved sanitation and hygienic conditions. Hence, considering existing challenges and opportunities to community at large, the town administration should plan upgrading or slum clearance of seriously affected old housing structures and put in place sanitary housing enforcements. Furthermore, with good private and public sector involvements, municipal water supply, solid and liquid waste system must be made accessible to all residents of the town hand in hand with promotion of participatory hygiene and sanitation information. Key words: Environmental health, healthful housing, improved water supply, sanitation, Solid and liquid waste mgt and hygiene practices

description: We explore thermodynamics of a quantum membrane, with a particular application to suspended graphene membrane and with a particular focus on the thermal expansion coefficient. We show that an interplay between quantum and classical anharmonicity-controlled fluctuations leads to unusual elastic properties of the membrane. The effect of quantum fluctuations is governed by the dimensionless coupling constant, $g_0 \ll 1$, which vanishes in the classical limit ($\hbar \to 0$) and is equal to $\simeq 0.05$ for graphene. We demonstrate that the thermal expansion coefficient $α_T$ of the membrane is negative and remains nearly constant down to extremely low temperatures, $T_0\propto \exp (-2/g_0)$. We also find that $α_T$ diverges in the classical limit: $α_T \propto - \ln(1/g_0)$ for $g_0 \to 0$. For graphene parameters, we estimate the value of the thermal expansion coefficient as $α_T \simeq - 0.23\:{\rm eV}^{-1}$, which applies below the temperature $T_{\rm uv} \sim g_0 \varkappa_0 \sim 500$\:K (where $\varkappa_0 \sim 1$\:eV is the bending rigidity) down to $T_0 \sim 10^{-14}$\:K.
