The supercritical airfoil has been widely applied to large airplanes for sake of high aerodynamic efficiency. But at transonic speeds, the shock wave on upper surface of supercritical airfoil may induce boundary layer separation, which would change the aerodynamic characteristics. The shock characteristics such as location and intensity are sensitive to Reynolds number. In order to predict aerodynamic characteristics of supercritical airfoil exactly, the Reynolds number effects of shock wave must be investigated.The transonic flows over a typical supercritical airfoil CH were numerically simulated with two-dimensional Navier-Stokes equations, and the numerical method was validated with test results in ETW(European Transonic Windtunnel). The computation attack angles of CH airfoil varied from 0oto 8o, Mach numbers varied from 0.74 to 0.82 while Reynolds numbers varied from 3×106 to 50×106 per airfoil chord. It is obvious that shock location moves afterward and shock intensity strengthens as Reynolds number increasing. The similar curves of shock location and intensity is linear with logarithm of Reynolds number, so that the shock location and intensity at flight condition could be extrapolated from low Reynolds number.

The completion of Todd and Bowman's ' Physiological Anatomy' will enable us to go fully into the merits of this important work in our next number, when we hope to couple with it the large volume on Human Physiology published by Dr. Draper, of New York. In Physiology we have also to mention the translation by Mr. Dallas of a work by Professor Siebold, ' On True Parthenogenesis in Moths and Bees,' in which the hitherto-disputed question of the existence of a Lucina sine concubitu is set at rest in the affirmative. With this class of books we must also range Dr. Holland's ? Constitution of the Animal Creation, as expressed in Structural Appendages,' under which quaint title the author enters into a minute disquisition on the hair, nails, and other parts of the animal frame, which may be regarded as mere appendages to the body. In Medicine we have first to mention Sir John Forbes' ' Inquiry into the relative Power of Nature and Art in Curing Disease,' which, we doubt not, will command an extensive circle of readers, and to which


This paper proposes a three- and a five-section microstrip 3-dB quadrature hybrid. Two types of enhanced coupling structures, both with a rectangular ground-plane aperture and two inserted signal strips in the aperture, are used in the quadrature hybrid not only to achieve tight coupling but also to minimize the junction effect between coupling sections. The designed circuits have a fully planar structure. They were fabricated on a single-layer substrate by the standard printed circuit board (PCB) manufacturing process.


Expressions for the exchange and correlation corrections to the model potential form factor wq(k) and the normalized energy-wavenumber characteristic FN(q), which were derived in a recent paper by Shaw, are evaluated for eight simple metals. An expression for the second derivative of the Kohn-Sham density functional for the exchange and correlation energy is proposed and then is used in these calculations. The energy-wavenumber characteristic computed from the optimum model potential, corrected for exchange and correlation, is used to calculate the phonon spectrum of magnesium. The predicted spectrum is found to agree very well with the experimental data, and the exchange and correlation corrections are shown to be important in obtaining this agreement. The corrections to FN(q) and wq(k) which are tabulated for eight metals can be used to determine the importance of exchange and correlation in the prediction of other metallic properties.


This paper investigates the present situation of the tennis development in colleges and universities of Shenyang by using the questionnaire, interview and statistics, and finds some obstacles to the development of tennis such as the shortage of tennis field, specific teachers, as well as the arrangement of the course; and then put forth some suggestions and countermeasures for its developing in the near future.


The information-extreme algorithm was developed of machine learning of the management system of a data center for predicting violations of the SLA terms. The scheme of binary encoding of features is considered, where the code of features is determined by the results of control of belonging of its value to the appropriate field of tolerances of each class of recognition. According to the data of tracing the work of virtual machines of a data center, we formed learning samples and synthesized decisive rules, optimal in information sense. The increase in reliability of decisive rules by 8 % is demonstrated, as compared to results of learning by the well-known scheme, where the control tolerances on the attributes' values are defined only for one single base class. We proposed to use extreme serial statistics in the form of normalized statistics of the numbers of the attributes' values entering their fields of control tolerances for determining the moments of retraining a management system that allows adapting to the change in patterns of consumption of resources of a data center. The efficiency of additive-multiplicative and entropy convolutions of the partial criteria of quality of functioning of a data center was examined to form the fitness function of swarm algorithm of optimization of the plan to deploy virtual machines of a data center. It is proved by the results of physical modeling that the additive–multiplicative convolution is more efficient on the stage of growth in the load of a data center, while the entropic convolution has highee efficiency during reduction in the load of a data center. In both cases, the decrease in operating expenses of a data center is observed in comparison to the known MBFD algorithm (Modified Best Fit Decreasing).


Despite the encouraging results of behavioral weight-loss interventions in effi cacy trials, primary care providers (PCPs) have expressed a lack of confidence that proven weight management models can be implemented in a primary care setting [1]. The Practice-Based Opportunities for Weight Reduction (POWER) trial conducted at Johns Hopkins University (MD, USA) compared the effectiveness of two behavioral weight-loss programs to a self-directed control group over 24 months among obese adults with at least one cardiovascular disease risk factor. In contrast to traditional efficacy studies that often enrolled convenience popula tions, POWER enrolled obese patients from primary care clinics and delivered interventions that could potentially be integrated into routine medical care. As a comparative effectiveness trial, our findings should be directly applicable to rou tine medical care and should inform patients, healthcare providers and delivery systems of effective treatment options [2]. This article highlights lessons learned from the design and implementation of the POWER trial. Details of the study design have been published [3,4]. Participants were obese patients from one of six participating primary care clinics, who had at least one cardiovascular risk factor (hypertension, hypercholesterolemia, or diabetes), regular internet access and basic computer skills (i.e., the ability to enter data into a website and send/receive email). Participants were randomized to one of three groups: control condition, remote intervention and in-person intervention. The primary outcome was weight loss at 24 months after randomization. The two behavioral interventions were based on previous trials conducted by the Hopkins investigative team that demonstrated the efficacy of lifestyle interventions in achieving and maintaining weight loss and improving cardiovascular disease risk factors [5–8]. The group receiving in-person support was offered group sessions, individual sessions (telephonic and in-person) and web support. The group receiving remote support was provided telephonic sessions and web support with no face-to-face contact. These active intervention groups were compared with the self-directed control group. A summary of the intervention recommendations and contact schedule have been published [3,4]. PCPs provided general encouragement for intervention participation and reviewed a one-page report of the participant's progress at regularly scheduled clinic visits for those in the active interventions. The main results have been published and a brief review follows [4]. Of the 415 randomized participants, 64% were women and 41% were African–American; mean (standard deviation) age was 54 (10.2) years, and mean (standard deviation) BMI was 36.6 (5.4) kg/m 2 . The median number of completed coaching sessions in the remote support arm was 14 during the first 6 months (15 sessions were offered), 1


In this study, the residual strength of the carbon/epoxy composite plates exposed to the thermal cycles and subjected to low-velocity impact was evaluated using an experimental procedure. Composite plates with a layup of [45/02/-45/902]s and thickness of 2.9 mm under three impact energy levels of 10J, 15J, and 20J and exposed to 200 thermal cycles in the range of -30 to 65° C went under low-velocity impact and compression after impact tests. In performing impact tests, a drop weight test device was used to investigate the behavior of damaged composites, force-time, force-displacement, and energy-time curves at all test temperatures were analyzed. Finally, the effect of temperature and associated damages at different levels of impact was evaluated using radiographic analysis and optical microscopy. Applying 200 thermal cycles in the temperature range of -30 to 65 ° C caused small cracks in the matrix and reduced the energy absorption of the samples. The highest drop in compressive strength is related to the highest impact energy, 20 J, which has a 31.12% decrease in strength. The thermal cycle at different impact energy levels of 10J, 15J, and 20J has led to an increase in the stiffness and compressive strength of the composite specimens. Finally, material parameters of the semi-empirical Caprino model to estimate the residual compressive strength of the carbon/epoxy plates under low-velocity impact and thermal cycles are obtained.


Numerical predictions are presented of separated, turbulent flow over a normal fence in a two-dimensional channel. The elliptic type governing partial differential equations are solved by finite difference method, k-e model is used as turbulence model, and it has been modified to account for the effect of streamline curvature in recirculation region. This was achieved by introducing a Richardson number correction in the equation for viscous dissipation. Computational results for wall static pressure are in good agreement with experiments.


Nowadays, in the world herbal plants have used extensively as food supplements and medicinal purposes as they are cheap and have little side effects. Use of different synthetic preservatives lead to negative health issues. Moreover, the use of synthetic compounds has significant drawbacks, such as increasing cost, handling hazards, concerns about residues on food, and threat to human environment. As a good alternative, herbs replace synthetic preservatives as natural, effective, and non-toxic compounds. Herbs (garlic, cumin, clove, basil, amla, pudina etc.) have been used as food additives since ancient times, as flavoring agents and natural food preservatives. Herbs also have antimicrobial activities against different types of microorganisms. The consumption of herbal medicines provide alternative treatment for alleviating a number of health problems including heart diseases, diabetes, high blood pressure, and even certain types of cancer. This research paper highlights potential benefits and possible risks associated with consumption of herbal products as jam, its organoleptic properties, shelf life and overall acceptability by the consumers.

Surveillance  under direct field-pond application of choline chloride in addition to farm-made-aqua-feed under semi-intensive culture system was investigated on the gonadal maturity  in  two Indian Major Carps Catla catla (Catla) and  Labeo rohita (Rahu) and in two air-breathing teleosts, e.g., Clarias batrachus (Magur) and Anabas testudineus (Koi) reared in a ratio of 2:5:1:1::  Catla:Rahu:Magur:Koi  for a period of 90-d both during dry [November to January as control-dry (CD) and treatment-dry (TD)] and  in breeding seasons [June to August as control-breeding (CB) and treatment-breeding (TB)]. Results were compared with control [C: pond (C) fed only with farm-made-aqua-feed] and treatment [T: ponds (P1 and P2) fed with farm-made-aqua-feed plus feed-grade choline chloride]. The histological observations of ovary under control condition in both the seasons (CD and CB) depicted the follicular layer separation, follicular atresia, resulting into non-fertile oocytes, and ovarian tissue necrosis, declination of yolk granules, while under choline supplementation in both the seasons (TD and TB), the fish species showed ripe and developed oocytes resulting into excellent reproduction performance and steroidogenesis as well as ovulation especially in breeding season. Besides, the exposure of choline (TB) has improved manifolds in the seminiferous tubules of testis of the experimental fish species with the development of increased sertoli cells, development of mature spermatozoa within the epidermis resulting into successful maturation of the sperm and occurrence of better sperm quality having increased motility especially in the breeding season. Finally, choline can trigger the successful ovarian maturation depicting better yield, causing substantial profit to fish farmers.


A very significant component of the collect ion of gold jewellery in the By zantine Museum of Athens consists of the Mytilene Treasure fro m the island of Lesbos. Despite the importance of the Mytilene Treasure, one of the most significant hoards of the 7th century A.D. fro m the Aegean area, no previous systematic study has been dedicated to it since its discovery in 1951, except for b rief entries in exh ib ition catalogues (Chalkia, 2008). The presence of Gemstones among the artefacts, set us the question of their mineralog ical identity. The samples which we study are the following BXM_875, BXM_872, BXM_178a, BXM_178b, BXM_873a, BXM_873b. The Raman spectroscopy measurements made in t he Laboratory of Physicochemical Analysis of By zantine & Christian Museum. The references on Gemstones in Byzantine literature are many and helpfu l(Stocchi M.,2009). Theophrastus of Eressos mentions that exist a kind of false emerald(Caley, 1956). In Christian Era Ep iphanios of Cyprus is described in his text emeralds (Ep iphanii Cypri, 4 cent.A.D.). Another interesting reference is the book of Damigeron (1rst cent. A.D.) which includes a description of emerald(Tahil, 2005). In By zantine Era Michael Psellus (11nth c. A.D.) in his text De Virtutibus Lapidorum made a reference on emerald. In accordance to our experimental results: the BXM_872 contains nine real emeralds, the circular amu let BXM_ 875 is a blue g lass with an addit ion of lapis lazuli, the earrings BXM_178a,b with the b lue stones are not sapphires but they are possible a kind of glass paste and the earrings BXM_ 873a,b are g reen glass.


Working within the non relativistic quark model a two parameter fit to the magnetic moments of baryons is presented. The fit has an excellent $\chi^2$. The model is based on taking different flavor groups to describe the different magnetic moments. The selection of which group to assign to each baryon is guided by the structure of its wavefunction. The model corresponds to assigning different effective masses to a quark depending on which baryon is being considered. Using the values extracted from the fit, the magnetic moments of the $\Omega^-$ and the $\Delta^{++}$ have been predicted and the comparison to the existing experimental values is quite satisfactory.


Detailed process of the tail slap for an underwater projectile in supercavitation is studied in this paper. Firstly, the horizontal equation of motion for the projectile and a dynamic model of the projectile's tail slap are introduced through a mathematical derivation, including a simple harmonic motion model of the projectile within the supercavitation layer and the tail slap reflection movement model inside the cavity. Subsequently, the MATLAB software package is used to model the projectile's motion. Characteristics for force from the projectile tail on the water layer during a single tail slap and the behavior of the projectile's angular motion as well as the characteristics of projectile tail motion through multiple tail slaps are investigated. It is found that the force magnitude of the water on the projectile tail decreases gradually while the relative motion angle of the projectile tail into the water layer and the contact time increase obviously as the projectile repeatedly slaps the cavity interface. When the projectile velocity decreases into a certain range, i.e., less than 50 m/s, the contact time of the tail in the water layer increases dramatically, and the supercavitation can tend to collapse and lead to unstable projectile motion. With increasing lateral deviation and angular velocity of the projectile tail, the number of tail slaps and the angle of reflection both increase significantly. In the case of supercavitation, the parameters of different tail slap points tend to be stable with time.


Abstract Background: The likelihood of conception is increased if intercourse is timed to coincide with the fertile period (5 days up to ovulation). However, to be effective, this requires good awareness of the day of ovulation. The aim of this study was to examine the accuracy of women's perceived ovulation day, compared with actual fertile days, in a cohort of women trying to conceive. Main outcome measures: Comparison of women's estimated day of ovulation with their actual ovulation day (determined by detecting luteinising hormone). Methods: This was a sample collection study and volunteer women were recruited via online advertising. At recruitment volunteers reported the cycle day they believed they ovulated. They then used a home urine fertility monitor to test their daily fertility status to time intercourse to try and achieve conception, in addition to collecting early morning urine samples for laboratory analysis. The main outcome measure was a comparison of women's estimated day of ovulation with their actual ovulation day, as determined by urine detection of luteinising hormone. Results: Three hundred and thirty women were recruited onto the study and data was available for 102 volunteers who became pregnant. Thirteen women (12.7%) correctly estimated their ovulation day; median difference +2 days, range −10 to +27 days. The most common days for estimation of ovulation were day 14 (35.5%) and day 15 (15.7%). Only 55% of estimated ovulation days fell within the volunteers' fertile window; only 27% on days of peak fertility. Conclusions: Women trying to conceive may benefit from using a prospective method to identify their fertile phase, as a significant proportion could be incorrectly estimating their fertile days. These observations were made on women who were actively looking for knowledge on fertility and considered only cycles where conception occurred, inaccuracy could be greater if a broader population is considered.


In the German school and vocational education systems, there is a wide range of support measures during school-to-work transition. We analyze a novel program providing mentoring to low-achieving school leavers. The program bridges different stages and different institutional systems in secondary and post-secondary education. Using high-quality survey and administrative data and propensity score matching, we find some positive effects on the probability of transiting into the dual vocational education system in the intermediate run. Higher program intensity leads to larger treatment effects. Contrary to the goals of the program, however, there is only weak evidence that it accelerates transitions into vocational training immediately after the first school-leaving certificate.


The genus Caladenia contains the largest number of threatened orchid species in Australia and improv- ing the success of re-introductions would allow exist- ing populations to be strengthened and new popula- tions to be established. Batty et al. (2006) showed that direct seeding of C. arenicola Hopper & A.P. Br. into habitat soil inoculated with mycorrhizal fungus resulted in a good in situ germination rates.


"I seek to trouble" is a common refrain in Allison Hargreaves's monograph about violence against Indigenous women in Canada. And "trouble" she does—providing hard hitting but thoughtful critiques of several common, contemporary activist efforts to address the tragedy of widespread violence in the lives of Indigenous women. A self-described "settler-scholar," Hargreaves analyzes how some mainstream efforts to address the disproportionate rates of violence experienced by Indigenous women can actually be detrimental to the cause. She repeatedly problematizes many well-known activist efforts by consulting and analyzing the perspectives of Indigenous women as expressed in film, art, and literature. As such, this volume is highly recommended for Indigenous studies and gender studies scholars. Moreover, it offers significant insight for activist communities of any stripe, who will benefit from Hargreaves' interrogation of common activist tactics. In the Introduction, Hargreaves establishes a bold proposition—that the most widelyrecognized strategies for addressing violence against Indigenous women in Canada are deeply problematic and potentially counter-productive. Seeking to understand how activism "can bring about the social and political transformation required to end violence," she begins by questioning the mainstream "awareness" campaigns that have come to be the hallmarks of anti-violence activism in Canada. As a literature scholar, Hargreaves proposes that the creative works of Indigenous women offer insights into the limitations of these mainstream projects. Thus, the book is structured by juxtaposing a strategy of anti-violence activism with a corresponding perspective as voiced through film, poetry, or fiction produced by Indigenous women. Hargreaves uses Indigenous film and literature as the window to critique and question the value of the liberal nation-state's most well-known efforts to acknowledge and resolve the historical oppression and colonial violence experienced by Indigenous women today. In Chapter One, Hargreaves critiques the British Columbia Missing Women Commission of Inquiry (MWCI), a 2010-2012 government effort to solicit testimonies from families, activists, service providers, and law enforcement agencies about missing and murdered Indigenous women, with a narrow focus on Vancouver's notorious Downtown Eastside, a common site of disappearance. Hargreaves critiques the MWCI efforts through the lens of Metis filmmaker Christine Welch's 2006 documentary Finding Dawn. Because the official MWCI activities were artificially conscribed and constrained as to scope and depth, many observers, including Hargreaves, saw the efforts as being a "missed opportunity to link the specific circumstances...to broader colonial patterns of systemic displacement and violence." Finding Dawn, on the other hand, offers an expansive perspective on the nature of missing and murdered Indigenous women. The film tells the story of three missing indigenous women by exploring themes of "hope, resilience, and transformation." By critiquing MWCI through the lens of an Indigenous filmmaker, Hargreaves is able to see a much larger and expansive project, one that focuses on the interrelationships between Indigenous women and the violent history of settler colonialism. One of the most important aspects of Violence Against Indigenous Women is that Hargreaves's critiques transcend the Canadian experience and become applicable in other settler nation-states. Several subjects explored by Hargreaves have striking parallels in the American context. Beginning in Chapter Two, she describes and critiques the Canadian Stolen Sisters report from Amnesty International issued in 2004. Amnesty International released a similar report in the United States (Maze of Injustice) in 2007, which explored the failure of the United States to adequately respond to sexual violence in Indian country. (In the interests of full disclosure, it should be noted that this reviewer collaborated with Amnesty International to research and write Maze of Injustice.) Hargreaves's criticism of the Stolen Sisters human rights report is cogent and much of her insight can be applied to Maze. For example, both reports assume "the legitimacy of the colonial nation-state to protect Indigenous women's rights" and utilize the stories of individual Indigenous women in a "certain narrative mould" that requires the primacy of victimhood to achieve reform. While not categorically condemning Home," first published by The New Yorker and later shortlisted for the 2017 Caine Prize, the character "Mama," landlady, employer and exploiter of the young mother Ogechi, sucks away at her joy and empathy. Here women need no man to procreate but instead make their babies out of materials they can find around them and then seek the blessing of their mother to bring their babies to life. If the mathematicians of the title story nurture people by taking in their pain, Mama does the opposite, performing the blessing in exchange for preying on their emotions. Ogechi reflects on "all that empathy and joy and who knows what else Mama took from her and the other desperate girls who visited her back room" in exchange for animating their children. Indeed, a child born of this kind of blessing, Ogechi discovers, will only continue the vampirism of her godmother. Like the half-bodied baby of Amos Tutuola's The Palm Wine Drinkard, her baby is never satiated. The story "Windfalls" is the prosaic but no less horrifying parallel to Ogechi's story. A mother pimps out her teenage daughter to help fund their peripatetic lifestyle, staging injuries as precedent for lawsuits. When the teenage Amara becomes pregnant, she begins to resist her mother's abusive lifestyle. Like Ogechi, she dreams of giving her child the nurture and home she never had. And while abuse and harassment is rampant in these stories, the sort of tenderness Amara feels for her unborn child lingers in other tales of families as well. If the stories deal with vampires, symbolic and real, who consume the "sorrow, tears, and blood" of those dependent on them, they also deal with the nurture of parents, the love between sisters, cousins, and friends, and the fire in the bellies of girls who refuse to let their souls be crushed. In the midst of suffering, there is also fierce love. In "Wild" the narrator holds close her humiliated and abandoned cousin and her illegitimate child. In "War Stories," the narrator recounts how her mother fights her father's traumatic stories of war with happy stories of her own childhood: "I listened with every atom and she animated the story with everything she had." In "Light," which won Arimah the 2015 regional short story Commonwealth Prize, a father raises his daughter alone while her mother travels to America to earn a degree. He nurtures her noisy laughter and spares her all the proprieties her mother tries to teach her over Skype. In his daughter, he sees a "streak of fire. He only knows that it keeps the wolves of the world at bay and he must never let it die out." "Light" and other stories show how difficult it is to keep that fire alive. In the final story, "Redemption," the narrator realizes that "Girls with fire in their bellies will be forced to drink from a well of correction till the flames die out." Yet while the stories in Arimah's collection are rarely optimistic, they are not without hope. Stubborn mud girls born of ash and sorrow re-emerge in story after story. Individually, these women have only their own fire to keep them going, but together they take inspiration from each other, even if it is only to spit on the path of their oppressor. In the mythic story "What is a Volcano," the wandering Bereaver eternally seeks the lost children of her sister River. Finally, when the "god-child cries" and her mother's body responds, a volcano forms. In the midst of despair, the fire still rumbles beneath the ground.

This talk will touch upon the challenges of running scientific workflows in distributed environments such as academic and commercial clouds. It will describe the Pegasus Workflow Management System [1] and how it manages the execution of a variety of scientific workflows. Pegasus is a system that maps high-level workflow descriptions onto the available, potentially distributed compute and data resources. It supports workflow reusability by making the same workflow description portable across infrastructures, including different clouds. A single workflow can run on a particular cloud or across heterogeneous clouds. Pegasus also optimizes the workflow from the point of view of performance and reliability. The talk will explore the options for data management, the impact of file system choice on performance, and general issues of resource provisioning. It will examine the interplay between resource provisioning and workflow execution, and how knowledge about the workflow structure and task characteristics can be used to make better resource provisioning decisions at runtime. The talk will describe the concept of a Shadow Queue and how it is used to predict future workflow needs. This information is then made available to a provisioning system such as the one based on ORCA (Open Resource Control Architecture) [2] to provision compute and network resources as needed while the workflow is executing.


A range of formulations of deltamethrin were prepared, some containing an ultraviolet (UV) absorber compound or a combination of the UV absorber and an oil, and applied to blue cotton tsetse fly target samples which were then exposed to the effect of simulated sunlight and water in the laboratory. The residue of insecticide remaining on the targets and the activity of the latter against tsetse flies was determined. Formulations containing the UV absorber and coconut oil or silicone oil remained the most effective against tsetse flies.

A coconut oil formulation of the insecticide was selected for field evaluation in comparison with a commercial deltamethrin formulation, Glossinex 200′ S.C., which contains 10% UV absorber. Target samples treated with these formulations were exposed to natural tsetse fly habitat in Ghana for a period of five months and evaluated for deltamethrin residues and activity against four species of tsetse fly. After five months, 4–13 times more deltamethrin remained on the targets treated with the coconut oil formulation than on those treated with 'Glossinex', and consequently the former were more active against tsetse flies than the latter. Target samples sequentially dipped in the coconut oil formulation resulted in uniform insecticide concentration on the targets, whereas those dipped in 'Glossinex' contained gradually decreasing deltamethrin concentrations.


The construction of the Cherenkov Telescope Array is expected to start soon. We will present the baseline methods and their extensions currently foreseen to calibrate the observatory. These are bound to achieve the strong requirements on allowed systematic uncertainties for the reconstructed gamma-ray energy and flux scales, as well as on the pointing resolution, and on the overall duty cycle of the observatory. Onsite calibration activities are designed to include a robust and efficient calibration of the telescope cameras, and various methods and instruments to achieve calibration of the overall optical throughput of each telescope, leading to both inter-telescope calibration and an absolute calibration of the entire observatory. One important aspect of the onsite calibration is a correct understanding of the atmosphere above the telescopes, which constitutes the calorimeter of this detection technique. It is planned to be constantly monitored with state-of-the-art instruments to obtain a full molecular and aerosol profile up to the stratosphere. In order to guarantee the best use of the observation time, in terms of usable data, an intelligent scheduling system is required, which gives preference to those sources and observation programs that can cope with the given atmospheric conditions, especially if the sky is partially covered by clouds, or slightly contaminated by dust. Ceilometers in combination with all-sky-cameras are plannned to provide the observatory with a fast, online and full-sky knowledge of the expected conditions for each pointing direction. For a precise characterization of the adopted observing direction, wide-field optical telescopes and Raman Lidars are planned to provide information about the height-resolved and wavelength-dependent atmospheric extinction, throughout the field-of-view of the cameras.


In this paper we derive both local and global geometric inequalities on general Riemannnian and Finsler manifolds and prove generalized CaffarelliKohn-Nirenberg type and Hardy type inequalities on Finsler manifolds, illuminating curvatures of both Riemannian and Finsler manifolds influence geometric inequalities.


In this article, I compare two distinct uses of "Popular Education" that emerged in Tlaxcala in the wake of the Mexican Revolution. I examine archival and oral evidence to reconstruct the situated meanings and political rationales that led to the use of the term in each case, beyond their contrasting pedagogical content. In 1917, a revolutionary faction promoted "popular education" by providing elementary schools throughout regions under its control, in order to secure legitimacy as a transitional government. In the late 1930s, the post‐revolutionary federal state launched a campaign of "popular education" ostensibly to promote adult literacy, which served to control radical teachers and consolidate a popular front in support of the incoming conservative presidential candidate. Simultaneously, the traditional rural pueblos negotiated and appropriated schooling and literacy for their own ends, in ways that at times went counter to those deployed by governing authorities. Noting the ambiguities of the terms pueblo and pueblos in Mexican history, I reconstruct both the logic of schooling for the people and the logic of schooling of the people. These particular histories point to the multiple rationales sustaining popular education projects, linked to the political and social movements that produced or resisted their actual implementation.


Abstract Introduction Breath tests utilising 13 C-labelled substrates for the assessment of gastric emptying have been applied widely. Wagner-Nelson analysis is a pharmacokinetic model that can be utilised to generate a gastric emptying curve from the %  13 CO 2 measured in breath samples. We compared Wagner-Nelson analysis with (i) scintigraphy and (ii) conventional breath test modelling to quantify gastric emptying in type 2 diabetes. Methods Thirteen patients (age 68.1±1.5 years, body mass index 31.0±0.9 kg/m 2 , HbA1c 6.3±0.2%) consumed a mashed potato meal comprising 65 g powdered potato, 20 g glucose, 250 ml water, an egg yolk labelled with 100 μL 13 C-octanoic acid and 20MBq 99m Tc-calcium phytate. Scintigraphic data were acquired and breath samples collected for 4 hours after the meal. Gastric emptying curves were derived based on each technique; the 50% emptying time and intragastric retention at 60 min were also calculated. Results With Wagner-Nelson analysis, a K el =0.60 (the elimination constant) best approximated the scintigraphic gastric emptying curve. There was a relationship between the T50 calculated with scintigraphy and by both Wagner-Nelson K el =0.60 (r 2 =0.45, P<0.05) and conventional analysis (r 2 =0.44, P<0.05). There was no significant difference in the 50% gastric emptying time for scintigraphy (68.5±4.8 min) and Wagner-Nelson K el =0.60 (71.3±4.5 min), however, the 50% gastric emptying time calculated by conventional analysis was much greater at 164.7±6.0 min (P<0.001). Conclusion In type 2 diabetes, gastric emptying of a mashed potato meal measured using a 13 C-octanoic acid breath test analysed with Wagner-Nelson K el =0.60 closely reflects measurements obtained with scintigraphy, whereas, in absolute terms, the conventional breath test analysis does not.


Regarding a growing interest into exploiting hyperspectral images in the plethora of applications such as chemical material identification, agricultural crop mapping, military target detection and etc., myriad approaches have been introducing to interpret and analyze such data. In this paper, I am going to propose a novel method using the combination of two conventional method. Firstly, I use an evolutionary algorithm i.e., multi-objective particle swarm optimization (MOPSO) to select a predefined number of features (spectral bands) and then a well-known classifier i.e., support vector machines (SVMs) is deployed for classification.


We often attend to one thing and lose another or go to extremes in the cross cultural research of the east and the west,inherit and innovate of Chinese traditional culture,and the indi- viduality and characteristics of companies during the process of discovering and practicing Chinese corporate culture.Aiming at the situation,the author discusses the problems from the angle of glo- balization,and proposes that the development and innovation of Chinese corporate culture should go toward the openness,nationality and individuality based on Chinese traditional culture and dif- ferent situation of different companies.The three characters have close relationships between each other.The paper is one of the series of the researches of the author.


One must grade House Republicans on a curve. As co-partisans of President Bush, they were the party of government. As the minority in the House, they were also the party of opposition. This combination severely limited their power and political choices. Nevertheless, they did manage to win some defensive victories and score some public-relations points.

In Vertebrates, seminiferous tubes are bordered with an epithelium producing gametes included between Sertoli cells. These cells were first described like a syncytium. With electron microscopy, the observations showed Sertoli cells contained a single nucleus and were limited by a classical plasma membrane. Some studies showed the Sertoli cells of anamniotes originated from follicle cells surrounding the cysts of germ cells. At the end of 1960's the paradigm of Sertolian syncytium was out. But Sertolian syncytium remained described during a long time. In anamniotes, Sertoli cells constitute the wall of cysts grouping germ cells. In burrowing or aquatic lengthened gymnophionan (caecilian) amphibians, the testes are constituted with several lobes containing locules in which spermatogenesis occurs. Light microscopy indicated gametes were grouped in cysts included into a filamentous matrix containing fat globules. Some nuclei were observed in a peripheral position. For a long time it was considered the Sertoli cells of these animals were limited to those nuclei with a very small cytoplasm. The use of SEM and TEM revealed the matrix belonged to the cytoplasm of Sertoli cells. The fibrous aspect corresponded to an artefact due to the fixative. The study of the testis development showed Sertoli cells were giant cells delimited with a plasma membrane. Finally, in these amphibians, the structure of Sertoli cells is reminiscent of the Sertoli cells belonging to other anamniotes.


Salinity is one of the environmental stresses limiting rice cultivation. Evaluation of the tolerance and sensitivity of offsprings of segregated generations under salinity condition is one way of finding tolerant cultivars. In order to study the effects of salinity (80 mM NaCl) stress on the second generation offspring of crosses of three rice varieties (Dollars and Gharib with 304) and to compare them with their parents and their classification in terms of salinity stress, the first experiment was conducted, adopting a Completely Randomized Design with four replications (i.e., crossing parents with Yasouj and Kamfirooz varieties). In the second experiment, check cultivars and the second generation progeny were evaluated, using an augment with a completely randomized design. At the germination stage, the Dollar cultivar was sensitive to salinity stress because it had the lowest ratio of all traits except germination percentage. However, Gharib and Kamfirooz Cultivars were salt tolerant. In both crosses, second-generation offsprings showed genetic variations in terms of the traits measured. Broad-sense heritability values for Dollars×304 and Gharib×304 crosses for shoot height (5.98% and 96%), root length (8.90% and 86%) and shoot fresh weight (8.95% and 7.92%), were relatively high, indicating that we can select these traits based on their phenotypes. General irritability for the shoot and root length traits in the second generation offsprings of Dollar and 304 crosses was higher than that of the second generation progeny of 304 and Gharib crosses. Based on these results, we concluded that for the purpose of improving salt tolerance at germination stage, 304 and Dollars crosses are more useful in rice breeding programs.


Street trees are more and more regarded as a potential measure to mitigate the excessive heat in urban areas resulting from climate change and the urban heat island. However, the current knowledge of the cooling effect of street trees relies on studies at the micro-scale while potential interactions at the city-scale are yet to be understood. In fact, the vast majority of large-scale modelling studies only represent street trees outside the street canyon, neglecting important effects such as the shading and sheltering.


An instance of the tollbooth problem consists of an undirected network and a collection of single-minded customers, each of which is interested in purchasing a fixed path subject to an individual budget constraint. The objective is to assign a per-unit price to each edge in a way that maximizes the collective revenue obtained from all customers. The revenue generated by any customer is equal to the overall price of the edges in her desired path, when this cost falls within her budget; otherwise, that customer will not purchase any edge. Our main result is a deterministic algorithm for the tollbooth problem on trees whose approximation ratio is O(log m/log log m), where m denotes the number of edges in the underlying graph. This finding improves on the currently best performance guarantees for trees, and up until recently, also on the best ratio for paths (commonly known as the highway problem). An additional interesting consequence is a computational separation between tollbooth pricing on trees and the o...


The total synthesis of (+)-Sch 725680, a member of the hydrogenated azaphilone family, has been accomplished. The synthesis confirmed the absolute configuration and biological activities of the natural product. A key reaction to construct a hydrogenated azaphilone core skeleton is a Ti-mediated aldol reaction.


Structural and acidic properties of the (001) surface of mordenite have been studied using density functional theory including generalized gradient corrections to the exchange-correlation functional. Our calculations, in agreement with experimental results, show that the surface structure of mordenite differs only moderately from the bulk structure, no reconstruction of the surface has been found. Part of the terminal silanol groups form weak hydrogen bonds with other framework oxygen sites, the lengths of hydrogen bonds vary in the range 1.9–2.6 A depending on the position of the Al site. The OH-stretching frequencies for various acid sites in the mordenite framework have been calculated. In agreement with experiment, calculated OH-stretching frequencies of terminal silanol groups are shifted by about 100 cm−1 with respect to the Bronsted acid sites. Those silanol groups whose OH-stretching frequencies are modified by the presence of hydrogen bonds are shown to absorb in the region typical for the Bronst...


The input index of public expenditure on education has not been achieved its goal in China over the past ten years. It closely relates to the fiscal capacity of the government,such as low proportion of financial revenue in GDP,inappropriate structure of fiscal burden,unbalanced regional economic development and related regional fiscal difficulties. It is hoped that in the next few years,with the development of economy and adjustment of financial and education policies,China could gradually build up its fiscal capacity,and achieve the input goal of public expenditure on education that the government has set for itself.

This paper aims to provide a remote fingerprint object authentication protocol dedicated to anti-counterfeiting applications. The corresponding security model is given. The suggested scheme is based on an Elliptic Curve Cryptography (ECC) encryption adding a mechanism to control integrity at the verification stage. The privacy constraint useful in many applications leads us to embed a Private Information Retrieval scheme in the protocol. As in a previous SPIE presentation, we begin with an optical reader. We drastically lower the amount of computation made at this stage.

The avian mite Dermanyssus gallinae (poultry red mite, PRM) is of major economic and veterinary importance for the poultry and egg industry worldwide. The accumulating reports on the opportunistic nonavian feeding of D. gallinae raise concerns on PRM host expansion. However, the consequent threats to human health remain largely unclear. PRM infestation in humans is usually manifested as a local or generalized noncharacteristic skin reaction referred to as gamasoidosis. This report presents the current state of the art and the new developments on PRM‐associated dermatitis, sharing neither the authors' personal experience nor focusing on differential diagnosis. Specifically, it reflects the outcome of the critical assessment of the available literature by European medical and veterinary experts in the field under the "One Health" approach.


The quantitative bivariate spatial pattern analysis was applied for the water quality and nutrients data of Masan Bay, and for this analysis Pearson's r as aspatial correlation measurement, Moran's I as spatial association measurement and L index as integration of aspatial and spatial measurement methods were used. To understand the aspatial and spatial characteristics implicated in L index, Pearson's r as well as Moran's I were classified into 3 types respectively, and Pearson's r and Moran's I were combined with 9 types, and also quantile of L index value was used for each of those 9 types. Finally, these types were defined as 5 groups having not overlapped L index range. According to the application result of L index groups, bivariate water quality and nutrients showed no aspatial correlation regardless of spatial association in February and July, but they showed aspatial correlation having clustered spatial pattern in May and November. The result of this study providing the guideline for the interpretation of aspatial correlation and spatial association using L index is expected to be helpful for the marine environment pattern analysis using quantitative index for further study.


In this study, we investigate the role of microRNA‐21 in anesthetic preconditioning, and its disruption in diabetic models. Anesthetic‐mediated cardioprotection has been shown to decrease myocardial infarct size after ischemia‐reperfusion injury. This response is drastically attenuated in diabetic patients. Many cell signaling pathways have been investigated in this phenomenon; however, the role of microRNA remains unknown. MicroRNAs are short, non‐coding nucleotide sequences that negatively regulate gene expression through degradation or suppression of messenger RNA.


Soil moisture is an important factor needed by plants for growth, and therefore the amount of soil moisture that can be stored depends on the type of soil or the composition of the soil-forming materials. Compost is one of the nutrients that is often used in the manufacture of planting media on land in the form of polybags, and the amount of compost composition on the soil is thought to greatly affect the ability to store water in the media. This study aims to test drip irrigation on a mixture of compost and soil on storage of irrigation water. Tests were carried out at a ratio of 70%: 30%, 50%: 50% and 30%: 70%. Irrigation was tested at a duration of 5 minutes, 10 minutes, and 15 minutes, and the data analyzed included irrigation distribution data, discharge, soil moisture data (w) and daily soil moisture change data. The results of the analysis are presented in the form of tables and graphs, then discussed and concluded descriptively. The results of the analysis show that the flow rate obtained is greater if the difference in water level to the land is greater, and the average Cu value obtained is 95.79% which is very good. With initial soil moisture in the range of 19%-25, soil moisture gain obtained by drip irrigation for 5 minutes -10 minutes is around 12%, and for a duration of 15 minutes soil moisture gain is obtained by 8% -21%. The lowest recharge was obtained on land with 30% soil and 70% compost of 8%-12%. The amount of soil moisture reduction after 24 hours of irrigation test was 6% - 17%, the lowest reduction was at 70% compost and 30% soil around 6%.


There are many instances in society, where people have certain disputes with one another, for example, conflicting claims or rights and an assertion of a right, claim, or demand on one side, met by contrary claims etc. on the other. In such cases, if the parties are unable to settle the dispute among themselves or by an Alternative Dispute Resolution (ADR) method they will straight away step into litigation.


Mass spectra of picolinic, nicotinie and isonicotinie acids and of their respective N-oxides are presented. Picolinic acid and its N-oxide demonstrate the facile loss of carbon dioxide and low-intensity molecular ions. Fragmentation is relatively simple. Nicotiuic and isonicotinic acids show very similar fragmentation patterns. For both, the molecular ion is the base peak. The fragmentations of nicotinic acid N-oxide and of isonicotinic acid N-oxide are more complex than those of the previous four compounds, but are similar to each other.


Chaozhou daluogu a traditional art form involving percussion, wind and string instruments, which originated in the Chaoshan region, South China. The genre revolves around the dagu , the leading drum and conductor of the ensemble. Chaozhou daluogu is deeply embedded in the regional Chaoshan culture through its connection with what is usually referred to as the youshen (god pageant ceremony').
From the legendary origins of the tradition – which its master performers trace back to the Tang dynasty – it is said to have kept original elements, but also undergone major change and development. Broadly accepted to have been re-defined to its present form by master Ou Xinu towards the end of the Qing dynasty (1644-1911), in the middle of the nineteenth century, it has been reinvented in a stage performance setting towards the middle of the twentieth century.
This thesis examines the dynamic history and current practice of Chaozhou daluogu primarily from the perspectives of its senior representatives, exploring its origins and development over time, introducing the instruments and performance setups as well as playing techniques, considering both traditional and contemporary repertoire, surveying transmission and learning experiences of major exponents, and trying to provide some insight into the sustainability of the genre into the future.


John Hopcroft asked me the following question a while back. It's a little off our normal track, but given that many people are away for the break, I thought I would share.


Deriving the criterion of a crack (joint) initiating under simultaneous effect of the rock stress state and elastic oscillations generated by an external source is a research purpose. Determining the quantitative relations to estimate the contribution of oscillations in crack initiation and create a theoretical basis for the improvement of rock burst forecasting technique is a goal as well. Methods. The brittle failure theory and a time-space approach are applied to determine a critical length of initiating cracks depending on stress level and amplitude-frequency characteristics of acoustic oscillations. Analysis of experimental data and comparison with the numerical results is carried out. Findings. Quantitative ratios between a critical length of the crack, a stress intensity factor, oscillation amplitude and a frequency are determined. It is shown that there are such values of the oscillation frequencies at which the critical crack length is especially sensitive relatively the amplitude alteration. The increase in the oscillation amplitude initiates starting the crack with small length. Numerical estimation is made for close-grained sandstone using such characteristics as crack resistance factor and Rayleigh' wave velocity and tensile strength. Increasing the amplitude twice at the frequency of 1145 Hz causes the reduction of starting crack length 3 times. Numerical results correlate with in situ data related to acoustic predicting the dynamic phenomena in the rock mass. Originality. The crack initiation criterion has been identified. Practical implications. Quantitative relations between stress components and amplitude-frequency characteristics should be used to improve the outburst forecasting technique and increase the reliability of dynamic effect prediction.


Polyamines do not interact with neutral phospholipids (phosphatidylcholines) but they do interact in the presence of bivalent and trivalent cations. The effect of polyvalent cations is explained in terms of dehydration of the bilayer surface. Polyamines interact strongly with negatively charged phospholipids; the presence of bivalent and trivalent cations do not change sensitively the type of interaction between polyamines and phosphatidic acids.

As you may know, people have look numerous times for their chosen readings like this in my brother s image twin brothers separated by faith after the holocaust, but end up in malicious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they cope with some infectious bugs inside their laptop.


The effect of reduced gravity on the fluid and electrolyte balance in astronauts is discussed. The acquired data indicate an early and marked sodium and potassium loss and a negative water balance. The conditions in astronauts may be likened to the syndrome of inappropriate secretion of antidiuretic hormone, but the mechanisms by which weightlessness causes a continued negative water and electrolyte balance, after the early shifts have occurred, are not clear. It is suggested that a transient increase in the release of the atrial naturetic factor and the altered gastrointestinal function may play a role in the initial and continued fluid and electrolyte changes, respectively.


The consolidation of economic and political relations in the North-Adriatic area and their formalization encouraged by the new institutional structures of Euro-regions are phenomena of central relevance to the actual European economic environment. These conditions have a significant influence on the strategic choices of local firms. In spite of the geographical proximity between Italy, Austria, Slovenia, and Croatia, cultural differences still act as important determinants in leading foreign investment strategies. The current study aims at analyzing the role played by cultural distance between the examined countries in affecting entry mode strategies followed by companies of the Italian region of Friuli-Venezia Giulia. In particular, the analysis suggests that a larger cultural distance, together with specific market characteristics, may force companies to choose entry forms with a lower degree of control, while specific firm characteristics may have an opposite impact on the internationalization strategies.

The chemical degradation processes of HDPE at 110 o C in air have been studied using light microscopy, FTIR analysis, micro-hardness and OsO4 staining. It is shown that carbonyl groups C=O, (as detected by FTIR) are formed only in the surface layer and the effect on mechanical properties is marginal. On the other hand the formation of isolated and conjugated C=C double bonds (as detected by OsO4 staining), show that cutting properties and micro-hardness are significantly altered. The progress of the degraded layer follows a diffusion process with sharp front and saturated concentration behind. An attempt is made to explain these observations by formation and mobility of free radicals. It is also shown that processing method, injection or compression moulding, can significantly influence the degradation process and the mechanical performance of the moulded component. based on initiation, propagation and termination of radicals, resulting in formation of more stable structures. Most reactions are dependent on the presence of oxygen and extraction of hydrogen. Solubility of oxygen in HDPE is sufficient for reactions, even at room temperature. Major functional groups formed are alkyl, alkoxy or peroxy radicals. Hydroperoxide are also formed and can decompose to hydroxy and peroxy radicals. Tertiary carbons are more reactive than secondary carbons and therefore have a shorter lifetime. Conjugated carbons are more stable than carbonyls and thus it can be expected that they dominate. Cross-linking also occurs and it will increase the strength but also the brittleness of the polymer. The number of possible reactions is very large and it is necessary to select those which are most common and result in more stable structures. The degradation process is most often studied using FTIR spectroscopy considering the formation of carbonyls (C=O) as the major chemical reaction. However the FTIR analysis indicate that most carbonyls are formed within the surface layer, exponentially decreasing with depth, leaving the major part of the polymer thickness un-degraded. This can be explained by photo-oxidation (17, 18). In the present work oxidation of HDPE is studied by comparing FTIR results with changes in mechanical properties, such as micro-indentation and cutting properties which, together with osmium tetroxide staining, reveal the concentration and progress of C=C double bonds. Injection moulded samples as well as compression moulded samples, (which have more homogeneous structure) are used. This shows the importance of polymer processing methods on the performance and durability of polymer components.


This paper presents a kinetic analysis of the previously published data on anaerobic digestion of cattle wastes based on the steady-state kinetic model proposed by Chen and Hashimoto (1978), and discusses optimum designs of anaerobic digester systems to utilize cattle wastes.

The clinical presentation, vascular reconstruction and a brief review of the literature are described.


Point cloud registration is challenging in the presence of heavy outlier correspondences. This paper focuses on addressing the robust correspondence-based registration problem with gravity prior that often arises in practice. The gravity directions are typically obtained by inertial measurement units (IMUs) and can reduce the degree of freedom (DOF) of rotation from 3 to 1. We propose a novel transformation decoupling strategy by leveraging screw theory. This strategy decomposes the original 4-DOF problem into three sub-problems with 1-DOF, 2-DOF, and 1-DOF, respectively, thereby enhancing the computation efficiency. Specifically, the first 1-DOF represents the translation along the rotation axis and we propose an interval stabbing-based method to solve it. The second 2-DOF represents the pole which is an auxiliary variable in screw theory and we utilize a branch-and-bound method to solve it. The last 1-DOF represents the rotation angle and we propose a global voting method for its estimation. The proposed method sequentially solves three consensus maximization sub-problems, leading to efficient and deterministic registration. In particular, it can even handle the correspondence-free registration problem due to its significant robustness. Extensive experiments on both synthetic and real-world datasets demonstrate that our method is more efficient and robust than state-of-the-art methods, even when dealing with outlier rates exceeding 99%.


Sildenafil is a selective phosphodiesterase type 5 (PDE5) inhibitor which has been successfully used in the treatment of erectile dysfunction. However, several adverse effects are associated with its clinical use. Among numerous undesirable central nervous system effects, proconvulsant effects were reported in some patients using sildenafil. Sildenafil was also reported to have proconvulsant effects on pentylenetetrazole (PTZ)‐induced clonic seizures in mice. By contrast, the drug exhibited weak anticonvulsant effects in amygdala‐kindling seizures in rat.

In this paper, a new dynamic model of a DFIG subjected to the multiphase inter-turn short circuit fault (ITSC) is proposed. This model can quantitatively describe the faults occurring in multiple phases of the stator and rotor. What's more, a state-space representation of this faulty model is also derived. Base on this model, an adaptive observer is developed which can provide an online diagnosis of the fault position and level by estimating the amount of the shorted turns for each phase.


Previous studies had explored the diagnostic or prognostic value of NRP‐1/CD304 in blastic plasmacytoid dendritic cell neoplasm (BPDCN), acute myeloid leukemia (AML), and B‐cell acute lymphoblastic leukemia (B‐ALL), whereas the expression and application value of NRP‐1/CD304 in other common hematological diseases have not been reported.


Delairea odorata Lem., an asteraceous perennial vine indigenous to southern Africa, has become naturalised and invasive in many subtropical regions including California, South Australia and Hawaii. Biological control offers a potential long term solution to the management of this species in exotic locations. This study analysed aspects ofthe biology ofD. odorata in its native environment to determine its suitability to classical biological control. To this end an examination of the reproductive biology and natural enemies of D. odorata was made. A study of the pyrrolizidine alkaloid profile was also conducted. Reproductive biology: Delairea odorata reproduces both sexually by seeds and asexually by stolons. The flowering season occurs over the autumn months from April to June. Results ofthe pollination trials indicate thatD. odorata is a cross compatible species and an obligate outbreeder. There is no specialised pollination system and the predorninant pollinators belong to the families Apidae, Syrphidae and Calliphoridae. Following pollination, numerous small achenes are produced. Laboratory trials indicate that these achenes germinate readily between 10 and 25 QC and, although germination occurs in both the light and dark, light clearly stimulates seed germination. Greenhouse trials conducted to determine the effect of light on growth and reproduction indicate that D. odorata is a shade tolerant species which shows plasticity in terms ofgrowth form and deployment ofbiomass in response to changes in light intensity. Growth rate and allocation ofbiomass to vegetative and sexual reproduction are highest at an intermediate light level. However, greatest allocation ofbiomass is to stem growth regardless oflight level. Natural enemies: Surveys for potential biological control agents against Delairea odorata were conducted in KwaZulu-Natal and several phytophagous species were associated with the plant. However, only one potentially suitable control agent was identified, a stem galling tephritid fly, Parafreutreta regalis Munro. Preliminary studies indicate this species to be fairly host-specific, a valuable asset if it is to be considered as a control agent. Furthermore, as D. odorata proliferates extensively by means of stem regeneration and elongation, galling of these growing points by P. regalis may limit stolon spread in exotic locations. Two species of parasitic wasp (Braconidae) were found to parasitise P. regalis pupae. IfP. regalis is to be used as a control agent the likelihood of parasitisation in the new environment must be determined.


The 9p21 locus, a strong risk locus for coronary arterial disease, has been also associated with other cardiovascular disease including ischemic stroke (IS) in Caucasians. However, the association between 9p21 locus and IS in Chinese Han population is still debatable because of ambiguous results reported previously. Genetic heterogeneity between Southern and Northern Chinese Han populations could be one of the reasons for this uncertainty. Four genetic variants selected from the three conjunctional LD blocks within the 44 kb candidate region on chromosome 9p21 were genotyped in 1,429 IS patients and 1,191 healthy controls from the Northern Chinese Han population. Among the four studied variants, the G allele of the SNP rs2383207 was significantly associated with IS with allele frequency 66.8% in patients and 63.4% in controls. This association appears to be dominant with an OR of 1.417 (p=0.003) for people with either GG or AG genotypes. We did not find any association for the other three SNPs (rs1333049, rs10757274, and rs10116277). Based our results, we conclude that the 9p21 locus is a susceptibility locus for IS in the Northern Chinese Han population; and the core risk region for IS is within an interval of less than 28kb.


This paper addresses an important topic in Earth System Modelling dealing with the reproducibility of the results when changing the HPC environment (hardware and software). In some way this can derive to how reliable and well written are the models developed. However this is not a new idea in this area. It is well known that different compilers, hardware, options in the compilers, etc... produce different results in the floating point operations, even when using the IEEE754 standard. How significant these results are, is what has to be well analyzed and it is important that the research community is aware of this topic, as it is well presented here.

Language development was examined in 24 children (mean age 11 years; range 5.8-15.7 years) with AED intractable epilepsy before and 6, 12, and 24 months after anterior temporal lobectomy, in a study by the Dutch Collaborative Epilepsy Surgery Programme (DuCESP) at University Medical Center Utrecht, The Netherlands.


Invertebrate gleaning within seagrass meadows is a common activity across eastern African communities that depend on fisheries for their livelihoods. Based on a case study of two contrasting sites, Maputo Bay (MB) and Inhambane Bay (IB), this study documents, both qualitatively and quantitatively, the gleaning activity, its value chain and stakeholders, paying particular attention to the recently created Locally Managed Marine Areas (LMMAs) within IB, boasting creativity in seagrass invertebrate fishery management. Twenty-four common edible species were identified for MB, and 15 for IB; nearly all gleaners were women and children. Our estimates indicate that about 7.7 and 7.6 tons of invertebrates are collected in the peak catch weeks (spring low tides) in MB and IB, respectively. Resources are caught and sold at local markets, food fairs (for IB only), and restaurants, as well as for direct household consumption. One thousand one hundred and seventy two (1172) hectares of LMMAs (corresponding to nearly 0.05 of IB) of fisheries management, together with existing community and other stakeholder engagement and intervention on value chains, are at the center of tangible invertebrate fishery management.


Unauthorized reproduction of this article is prohibited Pediatric Critical Care Medicine www.pccmjournal.org 1013 Fluid overload is increasingly accepted as a deleterious state in critically ill patients and has been associated with increased mortality, organ dysfunction, and prolonged need for mechanical ventilatory support (1–5). In adults, a conservative strategy of fluid management (restricted fluid intake and enhanced urinary output) resulted in improved lung function and shortened duration of mechanical ventilation and intensive care (5). More recently, the concept of fluid deresuscitation (removal of fluid using diuretics or renal replacement therapy) of critically ill adults has been developed and is associated with decreased mortality (6). In children, evidence regarding fluid overload in critical illness to date only supports an association with clinical outcomes, rather than causation (1, 3, 4). Fluid overload in children is associated with pulmonary dysfunction and prolonged mechanical ventilatory support (1–3), with increased cumulative fluid balance at day 3 being consistently associated with fewer ventilator-free days. Interestingly, the evidence so far suggests that our pediatric practice is similar to a liberal fluid management strategy in adults (1). The most recent consensus recommendations on pediatric acute respiratory distress syndrome (PARDS) address this issue recommending close fluid monitoring and titration of fluids to maintain adequate intravascular volume (7). In this issue of Pediatric Critical Care Medicine, Hassinger and Valentine (8) surveyed IV fluid (IVF) management practices in PARDS among physicians from the Pediatric Acute Lung Injury and Sepsis Investigators Network (PALISI) group. The authors designed a questionnaire with direct questions on several practices related to fluid management and two validation scenarios. Overall, most surveyed physicians agreed that fluid accumulation contributes to a worse outcome and should be prevented or treated. Interestingly, nearly half of responders reported starting IVF for children with acute respiratory failure to keep intake at maintenance, most frequently estimated using the Holliday and Segar "4-2-1" rate method, even though this practice could significantly overestimate fluid requirements of critically ill children (9). The survey also report that physicians rarely use 20 mL/kg fluid bolus for resuscitation, a deviation from current resuscitation guidelines that is likely to be influenced by the recent evidence on dynamic assessment of fluid responsiveness. In contrast, the choice of IVF is nearly exclusively composed of normal saline and Hartmann's solution, suggesting that the recent evidence from adults suggesting a benefit in outcome with use of balanced crystalloids has not affected physician's practices in a similar way. The majority of respondents report the use of fluid balance records (net input and output) for decision-making about fluid management and that 5% or 10% volume overload are the most commonly considered thresholds for interventions such as diuretics or fluid restriction. The clinical relevance of these thresholds could be significantly influenced by time and patient age, two topics that unfortunately were underexplored in the current survey, as well as underlying disease, chronic conditions, and severity of illness (4, 10). It is important to highlight some limitations of the current report. First, only PALISI physicians participated in the survey, so the external validity of the study by Hassinger and Valentine (8) is limited. Second, only 43% of this very select group of physicians responded to the survey. This generates a significant nonresponse bias that limits the reliability and the validity of the study findings. Last, the survey assessed self-reported practices, but these may significantly differ from actual patient management. Nevertheless, the study by Hassinger and Valentine (8) provides an important exercise of selfrecognition of our fluid administration practices and, more so, of physician awareness of the unintended presence of volume overload. The study by Hassinger and Valentine (8) also highlight how more recent research findings are being translated into clinicians' practices and the physician's awareness of current literature findings regarding fluid overload. In this regard, lessons learned from other clinical scenarios (e.g., critical illness hyperglycemia) may suggest that rapid implementation of clinical practice changes based on associative evidence needs to be done with caution. In addition, the surveyed group has little equipoise for a trial of conservative versus liberal fluid management in PARDS, since the majority of physicians already believe that fluid overload is deleterious to the patient and are actively treating it. From a research perspective, the group surveyed could focus on areas with more equipoise, such as the use of different thresholds for initiation of fluid management therapies or choice/effectiveness of fluid management treatments. Importantly, the study by Hassinger and Valentine (8) *See also p. e551.


We present an ISO Long Wavelength Spectrometer (LWS) grating spectrum of the carbon-rich proto-planetary nebula AFGL 2688 between 43 and 194μm. The far-infrared spectrum of AFGL 2688 is dominated by strong rotational transitions of CO which are detected from J=14-13 up to J=23-22. The atomic fine structure lines [O I] and [C II] are not detected. This is consistent with the cool central star of AFGL 2688 not having yet photodissociated the molecular gas ejected during the AGB phase. The far-infrared CO emission in AFGL 2688 appears to originate in shocked dense gas at a temperature of ~400K.


Objective: To express the rat Mature Peptide of Myostatin in Escherichia coli and purify Mature Peptide of Myostatin by using Glutathione S-transferase (GST) expression system. Methods: The Rat Mature Peptide of Myostatin cDNA, obtained from Rat gastrocnemius muscle via RT-PCR, was inserted into the prokaryotic expression vector pGEX-4T1 to express GST-Myostatin fusion protein in Escherichia col (E. coli) BL21(DE3) strain under the optimized induction of isopropyl-β-D-thiogalactopyranoside (IPTG). Western-blot analysis was performed using anti-GST antibody to confirm the fusion protein, which was then affinity purified by Glutathione-agarose chromatography. Results: DNA sequencing showed that Rat Mature Peptide of Myostatin gene nucleotide sequence obtained from RT-PCR was identical with that of Myostatin cDNA recorded in the GenBank. The maximum quantity of the fusion protein was produced at 16h after induction with 0.1mmol/L IPTG at 30°C. Western-blot analysis indicated that the recombinant protein could react specifically with anti-GST antibody. Conclusion: The recombinant gene of GST-Myostatin was constructed successfully and the fusion protein was expressed effectively in E. coli cells. These results suggest that the reported method would be useful in obtaining a large quantity of Rat Mature Peptide of Myostatin, which would contribute to the further study on Rat Mature Peptide of Myostatin antibody production.

A 69-year-old man with hyperlipidaemia presented to the emergency department with a 4-day history of new onset pain in the neck. The pain was severe (rated 9/10 in severity), constant, localised to the base of the skull and was associated with significant restriction of neck motion; any movements resulted in dramatic worsening of the pain. He also reported subjective fevers at home. He did not report trauma, photophobia, phonophobia, nausea, vomiting, insect bites, visual disturbances, trouble swallowing or speaking, jaw claudication or morning stiffness. There were no sick contacts. He did not have pain at any other sites. He had tried some topical diclofenac gel for the past 2 days without much relief. His only scheduled medication was atorvastatin.

On physical examination, his temperature was 38.1°C, blood pressure was 128/82 mm Hg, heart rate was 82/min and respiratory rate was …


There has been growing interest in applying the artificial neural network (ANN) approach in structural system identification and health monitoring. The learning process of neural network can be more robust when presented in the Bayesian framework, and rational architecture of the Bayesian neural network is critical to its performance. Apart from number of hidden neurons, the specific forms of the transfer functions in both hidden and output layers are also crucially important. To the best of our knowledge, however, the simultaneous design of proper number of hidden neurons, and specific forms of hidden‐ and output‐layer transfer functions has not yet been reported in terms of the Bayesian neural network. It is even more challenging when the transfer functions of both layers are parameterized instead of using fixed shape forms. This paper proposes a tailor‐made algorithm for efficiently designing the appropriate architecture of Bayesian neural network with simultaneously optimized hidden neuron number and custom transfer functions in both hidden and output layers. To cooperate with the proposed algorithm, both the Jacobian of the network function and Hessian of the negative logarithm of weight posterior are derived analytically by matrix calculus. This is much more accurate and efficient than the finite difference approximation, and also vital for properly designing the Bayesian neural network architecture as well as further quantifying the confidence interval of network prediction. The validity and efficiency of the proposed methodology is verified through probabilistic finite element (FE) model updating of a pedestrian bridge by using the field measurement data.


Cultural heritage preservation is crucial for appreciating past human accomplishments, and learning from their actions. A step towards this goal is identification and registration of archaeological monuments. While experts are able to manually inspect archaeological sites and document their findings, different measures have been taken to automate the process while leveraging human expertise, leading to a more efficient documentation of interesting archaeological landscape structures and monuments. One effective method is using LiDAR data or one of its derivatives, such as Digital Terrain Models (DTMs). Archaeologists use these data to manually identify, label, and keep records of interesting monuments and structures. In an attempt to automate the process, Meyer et al. (2019) used LiDAR data and the eCognition tool by Trimble (2014) to detect monuments such as ridge and furrow areas, burial mounds, and Motte-and-Baily castles. To automate the process even further, labelled DTM data can be used by different techniques in artificial intelligence, specifically deep learning, to train a model that learns to distinguish distinct objects. The trained models can then detect similar objects and label them in regions not inspected manually by archaeologists. Deep learning models can learn to classify, i.e., produce a label or category for a given segment of the DTM. It can also learn to categorize each point in the given DTM to a specified class. The former technique is referred to as classification while the latter is called semantic segmentation. Additionally, another technique called instance segmentation takes an input, and gives as output a bounding box, semantic segmentation mask, and a class label for each instance in the input. While all of the three techniques have proved to be effective, they highly depend on a large volume of labelled data to learn recognizing objects. In our research, the task is to detect archaeological structures. In this work, we focus on examples of bomb craters, charcoal kilns, and barrows in the Harz mining region of Lower Saxony, Germany, which is home to the UNESCO world heritage site, "Historic Town of Goslar, Mines of Rammelsberg, and the Upper Harz Water Management System". While a DTM for the whole state of Lower Saxony is available with a resolution of half a meter per pixel, only parts of the region of interest in Harz are labelled with known object categories. There are 38024 unlabelled DTM patches with a dimension of 2016x2016 pixels. The categories for which ground truth labels are available are listed in Table 1. Category Examples Minimum Diameter Average Diameter Maximum Diameter Bomb Craters 157 2.5 meters 6 meters 10 meters Charcoal Kilns 1044 4 meters 11.5 meters 19 meters Barrows 431 4 meters 17 meters 32 meters Table 1. Data Statistics for labelled examples Previous works by Politz et al. (2018), Trier et al. (2019), and Kazimi et al. (2018) show satisfactory results using the classification technique. Semantic segmentation also produces promising results, as discussed in the works of Kazimi et al. (2019a). Finally, instance segmentation technique applied on DTM data by Kazimi et al. (2019b) show comparable results. While these results are significant, they depend only on the limited amount of available labelled data. In the current research, a semi supervised deep learning technique, deep convolutional autoencoder, is used that makes use of unlabelled DTM data available for the whole state of Lower Saxony. This approach involves two steps. In the first step, referred to as unsupervised pre-training, a model is trained to learn to produce a compressed, lower dimensional representation of a given DTM input, and use this representation to reconstruct the original DTM. In the second step, supervised training, the model is further trained on the labelled data to learn labels for each point in the input, as in semantic International Conference on Cultural Heritage and New Technologies | Vienna | 2019 2 segmentation approach. In this approach, the model generalizes better, and learns to capture the data distribution from the unlabelled data well enough to create a distinct and representation for each input DTM segment (Erhan et al., 2010, Vincent et al., 2008). This is a more general representation than just using the labelled data, and hence, it improves the result of semantic segmentation in the second step of the approach. The architecture of the model is depicted in Fig. 1. This is the well-known DeepLabV3+ architecture by Chen et al. (2015). The preliminary results for the experiments in this research are shown in Fig. 2 and Table 2. Fig. 1. Architecture of the autoencoder. After unsupervised training, the number of filters in the last convolutional layer is changed to be equal to the number of classes, and the activation function is changed from tanh to softmax. The model is then trained further to perform semantic segmentation and produce labels for each pixel in the input.

Evaluation results. DLV3+ is the original semantic segmentation model trained on 80 percent of the labelled data and evaluated on the remaining 20 percent. Pretrained DLV3+ is the model first used as an autoencoder and trained on the unlabelled data, and then trained as a semantic segmentation model similarly on 80 percent of the labelled data and evaluated on the same 20 percent. In the supervised training step, both models are trained for 100 epochs with the same hyperparameters. The numbers are all in percentage and the best results are in bold. Pretraining with unlabelled data improves model recall and Intersection over Union (IOU), and it is more significant in the case of charcoal kiln examples, which are smaller in area compared to bomb craters and barrows.

During the development of an enhanced geothermal reservoir (EGS), production efficiency may be significantly affected by the heterogeneity of fracture conductivity. To avoid any dominant flow path that may "short-circuit" the fluid flow between the injector and producer, we presented the idea of autonomous tunable fracture conductivity and explored its potential benefits in production. The presented technique can provide high hydraulic conductivity in fractures when the surrounding temperature is high and vice versa low conductivity at low temperatures. Results show that utilizing this technique could prevent an early appearance of the dominant flow path between injector and producer in an EGS. By applying this technique, the output thermal power after 50 years of production can be increased by over 30 %, which is considerable for the EGS production. Since other flow-control systems are mainly focused on the wellbore and near-wellbore areas, this technique can provide a more effective enhancement in heat extraction by controlling flow deep inside the reservoir.
