[1] The 2000 Nemuro-Hanto-Oki earthquake (Mw6.8) occurred in the southwestern part of the Kuril Trench. The hypocenter was located close to the aftershock region of the great 1994 Kuril earthquake (Mw8.3), named "the 1994 Hokkaido-Toho-Oki earthquake" by the Japan Meteorological Agency, for which the fault plane is still in debate. Analysis of the 2000 event provides a clue to resolve the fault plane issue for the 1994 event. The hypocenters of the 2000 main shock and aftershocks are determined using arrival times from a combination of nearby inland and submarine seismic networks with an improved azimuthal coverage. They clearly show that the 2000 event was an intraslab event occurring on a shallow-dipping fault plane between 55 and 65 km in depth. The well-focused aftershock distribution of the 2000 event, the relative location of the 1994 event with respect to the 2000 event, and the similarity between their focal mechanisms strongly suggest that the faulting of the great 1994 earthquake also occurred on a shallow-dipping fault plane in the subducting slab. The recent hypocenter distribution around the 1994 aftershock region also supports this result. Large intraslab earthquakes occurring to the southeast of Hokkaido may occur due to a strong coupling on the plate boundary, which generates relatively large stress field within the subducting Pacific plate.


It started with a small group of activists trying to defend a public park against government's plans to build a huge shopping mall. In few days, as police used increasing violence against that tiny cluster of protestors, more and more people came to show their support. On 31 May, the whole country woke up at 3 a.m. to find that a small protest had turned into a huge revolutionary moment. Taksim Square and Gezi Park (in central Istanbul) were 'captured' on 1 June and remained government-free zones for two weeks... It was a bit ethereal for everyone: a stateless mega city-centre! The Taksim Commune! And anarchists were clearly not the only people who enjoyed the temporary autonomous zone. The heterogeneous movement was politicised through a common process. Different political stances converged for the first time. There was clearly a 'multitude' on the streets during the uprising and this multitude is still active in different forms. What happened, how did it develop? I believe that the events repay discussion.There are aspects of Gezi resistance that are truly local and you need to under- stand the Turkish political and social background to be able to connect fully to the events. On the other hand there are so many similarities, even links with other inter- national uprisings and movements, that the protest seems very familiar. I would like to suggest placing the Gezi resistance in the context of the 2011-2013 uprisings, that is, the new wave of resistance that has emerged in the aftermath of the anti-globali- sation movement (whatever we call it). Many aspects of 2011-2013 events resonate with the Zapatistas in 1990s. The encuentros in Chiapas and the writings of Marcos make sense of what is happening in Turkey. For me, this as a new web of radicalism and the main outcome is not overtly 'political'; rather, it is about the empowerment of people. Gezi has transformed Turkish people.As to the details: the festival-like atmosphere of Taksim after the police withdrew was very interesting. The square was full of revolutionary groups and parties. But none were able to control the festival, so to speak. In a typical May Day celebration in Turkey, for example the one I witnessed on 1 May 2012, (which was also held in the Taksim Square), there was one main programme, one focus; it was a very good plan and it involved a lot of security. Huge flags, huge placards, all displaying the glory of the revolutionary parties. It was a grandiose show. The 31 May uprising and the June TAZ in Taksim was instead based on 'affect' rather than flamboyance. There was room for everyone's creativity. People made jokes everywhere: on the walls, on upturned police vehicles, on signs; there were performances in every corner of the square, not all by artists but some by activists, even some by passers-by. Some helped to design a park library. People used a police car to make a wish tree, like Yoko Ono's Wish Trees.1 There were live concerts in various parts of the square, different types of music. Some groups marched and chanted, others worked on an indie radio station, organised painting workshops for children, or just shouted against the government... The Gezi Resistance included apolitical youth, precarious employees, workers, activists, anarchists, Marxists, Kemalists, teachers, lawyers, doctors and most importantly many artists. This movement was initiated by a new generation of young activists but their mothers supported them too, conquering bread: giving food, helping youngsters to protect themselves against police brutality. For many it was the first political action they had taken part in. After the government inflicted a series of oppressive actions designed to transform Turkey into an Islamic authoritarian regime, people reacted.The Gezi Resistance was an internet-based uprising, a Twitter revolution if you like. Facebook, Twitter and other internet environments were de facto places of the resistance. The anarchistic organisational principles of the original activists in Gezi Park subordinated ideology to practical action and attracted thousands of people who have never been involved in a demonstration before and who wanted to help the activists. …

Wavelength conversion and Routing and Wavelength Assignment(RWA) algorithms are the two key methods in improving the blocking performance in wavelength-routed all-optical networks.Considering the characteristics of tree network,this paper analyzed the key factors that affect wavelength converter placement.Combining pass length,pass loader and degree of node,we propose Wavelength Converter Placement Algorithms based on Network Center and Wavelength Converter Placement Algorithms based on Network Diameter.Through algorithms illustrating and simulating,it has been shown that the two kinds of algorithms we promoted have its advantages.


A perturbation theory‐based algorithm for the iterative orbital update in complete active space self‐consistent‐field (CASSCF) calculations is presented. Following Angeli et al. (J. Chem. Phys. 2002, 117, 10525), the first‐order contribution of singly excited configurations to the CASSCF wave function is evaluated using the Dyall Hamiltonian for the determination of a zeroth‐order Hamiltonian. These authors employ an iterative diagonalization of the first‐order density matrix including the first‐order correction arising from single excitations, whereas the present approach uses the single‐excitation amplitudes directly for the construction of the exponential of an anti‐Hermitian matrix resulting in a unitary matrix which can be used for the orbital update. At convergence, the single‐excitation amplitudes vanish as a consequence of the generalized Brillouin's theorem. It is shown that this approach in combination with direct inversion of the iterative subspace (DIIS) leads to very rapid convergence of the CASSCF iteration procedure. © 2019 Wiley Periodicals, Inc.


At the Naiman Desertification Research Station,CAS,the cultivated croplands for 10and20 years were selected as the experimental sites,with the adjacent fenced grassland as a control in order to probe into the effect of the cultivation of sandy grassland on taxonomical and trophic structure of soil arthropods.The results showed that the density,taxa richness,diversity index and biomass of soil arthropods all tended to decline with the conversion of sandy grassland to agriculture.The density and taxa richness were pronounced by the conversion,suggesting the significantly higher values in the sandy grassland compared with the agriculture(p0.05),regardless of cultivation time.Meanwhile,the density and taxa richness of predators and herbivores both tended to decline with the conversion of sandy grassland to agriculture,where the density of predators was significantly higher in the sandy grassland compared with the agriculture(p0.05),regardless of cultivation time.However,the predator biomass indicated different pattern from herbivore biomass,suggesting significantly higher predator biomass in sandy grassland and10-year cultivated cropland compared with the 20-year cultivated cropland(p0.05).The predator-prey interactions based on the density,richness and biomass was found to indicate no significant differences between the three treatment sites(p0.05).It was concluded that the cultivation of sandy grassland indicated a negative impact on the diversity and trophic indices of soil arthropods,where the cultivation time showed little effect on the diversity indices.The predator-prey interaction was not affected by the cultivation,also with time,whereas a marked effect of cultivation time was found on the predator biomass.


ABSTRACT Acetaldehyde is one of the crucial gases with odor released during the early stage of spontaneous combustion of coal, and it is essential for predicting the spontaneous combustion tendency of coal. In this study, we systematically investigated the effects of coal metamorphic degree, coal temperature, coal particle size, and oxygen concentration on the release of acetaldehyde using three coal samples with different metamorphic degrees and a combination of oxidation and warming processes as well as gas and liquid chromatography. The results showed that with the increase in temperature, the amount of acetaldehyde released first increased and then stabilized or slightly decreased. The amount of acetaldehyde released at low temperatures was linearly related to oxygen consumption. The higher the degree of coal deterioration, the lower the amount of acetaldehyde released. As the particle size decreased, the amount of acetaldehyde released increased and then decreased. Finally, four warning levels were established based on the concentrations and trends of acetaldehyde together with other index gases.


X-ray absorption spectroscopy is one of the most widely used experimental techniques to study the electronic and spatial structure of materials. Fluorescence yield mode is bulk-sensitive, but has several serious problems coming from saturation effects. In this study, we show the usefulness of partial fluorescence yields in addressing these problems. We discuss the different behaviors of La2NiMnO6 and LiMnO2 at the Mn 2p absorption edges. The total fluorescence yield produces misleading spectra for LiMnO2 due to the absence of high-Z (Z: atomic number) elements. We conclude that the measurement of the inverse partial fluorescence yield is essential in studies of LiMnO2, which is a hotly debated Li-ion battery material.


Humified Soil Organic Matter (SOM) plays a crucial role in the assessment of soil quality since it makes up a significant part of the total organic carbon and nitrogen in soils. High concentrations of humic and fulvic acids may be presents in soils and subordinately in sediments. These substances can potentially act as a significant reservoir of adsorbed boron as well as a source of this element to soil solution, rivers, and lakes. The aim of this study was to investigate boron in humic substances (e.g. humic and fulvic acids) of soil epipedon. The San Vitale pinewood was selected as the study site and three samples - classified as Sodic Psammaquents and Typic Psammaquants - of the A1-horizon epipedon were analyzed for humic and fulvic acids and boron contents. The knowledge of the mechanisms of boron interaction with SOM is important for a better understanding of the water/rock interaction in the superficial soil environment, and to envisage the application of the blending of boron into humic acid granules in agricultural practices.

Supplemental Digital Content is available in the text. Objective: This meta-analysis aims to compare the relationship between phenotypic manifestation of coronary and carotid atherosclerosis using available imaging techniques. Approach and Results: We searched all electronic databases until October 2020 for studies which reported relationship between carotid and coronary atherosclerosis. The primary end point was correlation between carotid intima-media thickness (CIMT) and carotid plaque features (calcification and lipid-rich necrotic core) with coronary artery disease (CAD). Secondary end points included carotid pathology that predicts CAD. Eighty-nine papers with 22 683 patients comparing carotid and coronary atherosclerosis were included in the analysis. CIMT was increased linearly with severity of CAD irrespective of its significance (P<0.001), mono versus 2 vessel disease (P=0.003), and 2 versus multivessel disease (P<0.001). Carotid plaque presence and calcification were less, and lipid-rich necrotic core was highly prevalent in nonsignificant versus significant CAD (P<0.001, P=0.03, P<0.001, respectively). Moderate correlation was found between CIMT and severity of CAD (r=0.60, P<0.001) and the number of diseased vessels (r=0.49, P<0.001). There was a moderate correlation between carotid and coronary stenosis (r=0.53, P<0.001) and between carotid and coronary calcification (r=0.61, P<0.001). CIMT ≥1.0 mm with a summary sensitivity of 77% and summary specificity of 72% and respective values of 80% and 67% for carotid plaque were the best predictors of CAD, irrespective of the technique used for its diagnosis. Conclusions: These results support the concept that atherosclerosis affects both carotid and coronary systems, although not always in identical phenotypic manner. These findings highlight the beneficial examination of carotid arteries whenever CAD is suspected.


The paper describes how in Italy new relationships have been created between Urban Facility Management (UFM) and the facilities project, advanced production systems in the building & infrastructure sector, the growing market for technical-management of facilities, the real estate financial market, contract management and, finally, quality culture. In this context, the paper also represents the premise of the scenario in which to place and later analyse some significant initiatives that has recently been developed in Italy and which can be considered as UFM best practice and case studies, especially in the public sector. ___________________________________________________________________________________ Today in Italy, the aims and scopes of Facility Management (FM) are increasingly concerned with the applications of all the sub-systems constituting the town-system at underground, ground and above ground levels and which can be classified as follows: 1. the underground level − techno-networks (electricity, gas, water, etc.) − info-networks (info-wiring) 2. the ground level − streets & squares − urban furniture − green areas & parks − lighting & traffic lights 3. the above ground level − single buildings − real estate − historical monuments − infrastructures (railway stations, airports, etc.). With this global vision, and from a social and technical perspective, FM takes on new dimensions, integrating and enlarging "real estate FM" to become "Urban FM" (UFM). UFM could be defined as an integrated approach to the management of urban facilities to maintain/increase the specific levels of quality of the same facilities and the global level of quality of the whole city. "Urban global quality" can be considered in terms of the efficiency, functionality, value, economy, safety, durability and the appearance of facilities. In Italy, ithe light of this important passing of scale, from the context of a mainly "real estate" application to an "urban" one, it can be said that UFM has now become one of the most innovative trend of the entire FM market: in the light of the change of scale and market conditions, FM is developing in a new dynamic context of legislative, technical-normative, cultural-operative and market innovation. Over the last few years the Italian economic boom in FM has been accompanied by a process of considerable and marked innovation in the sector, which has resulted in it being


Magnetic resonance imaging (MRI) is a practical tool for diagnosing tumors in human brain. In this work, MRI images are analyzed to find tumor‐containing regions and classify these regions into three different types of tumor: meningioma, glioma, and pituitary. Several methods were utilized previously for brain tumor detection, but no one method classify the brain tumor accurately and also it takes high computation time. To overwhelm these issues, a support vector machine optimized with seagull optimization algorithm (SOA) is proposed for brain tumor classification (SVM‐SOA‐BTC). The brain MRI images are gathered via Brats image dataset. Then the images are preprocessed using Savitzky–Golay denoising method. Then residual exemplars local binary pattern based feature extraction is utilized for extracting radiomic features. Then, the extracted features are fed to SVM classifier for classifying the brain tumors, like normal and abnormal. Then the weight parameters of the SVM are optimized using the SOA. The simulation is implemented on MATLAB. Then the proposed SVM‐SOA‐BTC method achieves 33.78%, 19.69%, and 11.62% higher accuracy; 30.62%, 25.05%, and 9.10% higher F‐score compared with existing methods, like Deep‐CNN‐DSCA‐BTC, CNN‐WHHO‐BTC, and AFDNN‐FLA‐BTC respectively.


The Hawking effect can be rederived in terms of two-point functions and in such a way that it makes it possible to estimate, within the conventional semiclassical theory, the contribution of ultrashort distances at I{sup +} to the Planckian spectrum. The analysis shows that, for Schwarzschild astrophysical black holes, the Hawking radiation (for both bosons and fermions) is very robust up to very high frequencies (typically two orders above Hawking's temperature). Below this scale, the contribution of ultrashort distances to the spectrum is negligible. We argue, using a simple model with modified two-point functions, that the above result seems to have a general validity and that it is related to the observer independence of the short-distance behavior of the corresponding two-point function. The above suggests that only at high emission frequencies could an underlying quantum theory of gravity potentially predict significant deviations from Hawking's semiclassical result.

The discharge of gaseous radionuclides from partly failed containers in a nuclear waste repository in unsaturated rock is studied by analytic solutions of the equation of gas flow. Nuclear waste containers are filled with an inert gas. After an initial rapid heating, which causes the pressure inside the container to increase, the repository will cool In this paper the authors consider a hole occurring in the first 100 yr or when the temperature is decreasing approximately exponentially. Using this approximation, the authors obtain an analytic solution for the gas pressure and velocity as a function of time. Using equations for steady-state advective-diffusive mass transport in the tube, the authors calculate the release rate of a contaminant gas such as {sup 14}CO{sub 2} using velocities calculated from the analytic solution.


Objective To study the relationship between serum sialic acid(SA),high-sensitivity C-reactive protein(hs-CRP),UACR and the prehypertension,thus to improve the scientific basis of early prevention for hypertension.Methods The SA,hs-CRP and UACR of the hypertension group,prehypertension group and normal blood pressure group were detected to compare the difference of these three groups.Results The SA,hs-CRP and UACR levels of the hypertension early group were higher than those of the normal group(P 0.05),and the SA,hs-CRP and UACR levels of the hypertension group were higher than those of the hypertension early group(P 0.05).The Pearson correlation analysis showed that SA,hs-CRP test results were positively correlated with the development of hypertension(P 0.05).Conclusion The determination of SA、hs-CRP and UACR could be used to assess the early hypertension,and improve the scientific basis of early prevention for hypertension.


Automated lumber grading and yield optimization using computer controlled saws will be plausible for hardwoods if and when lumber scanning systems can reliably identify all defects by type. Existing computer programs could then be used to grade the lumber, identify the best cut-up solution, and control the sawing machines. The potential value of a scanning grading system depends on the accuracy and reliability of the computer-assigned grades compared to the performance of human graders. The potential worth of any scanning cut-up system is largely dependent on the parts recovered compared to today's standard rough mill processing systems. The Center for Automated Processing of Hardwoods' (CAPH) scanning system is a color line-scan camera-based image processing system. We compared the system's scanning-grader performance with the NHLA grades assigned by company graders. The scanning-grader results indicated that 4 of 15 company graded boards were graded too high. In total, 67 percent of the boards were manually misgraded. Initial results indicate that the CAPH system is missing small sections of some defects and is misclassifying some clear wood as defective. We also compared the CAPH system's scanning-optimization system to a rip-first rough mill processing system. The scanning-optimization results indicated a potential increase in rough part yield of 5 percent might be realized with the CAPH system.


India's food subsidy system has been a major component social welfare programme ensuring the reach of food grains at affordable prices to the economically weaker sections of the society, helping to reduce malnutrition, ensuring price stability and thus food security (World Bank, 1986) in the country. The governments have perceived that the supply of rice to the poor families at cheaper price is fundamental importance to ensure food security through the welfare schemes like Antyodaya Anna Yojana (AAY), Annapurna (AP) etc. The outflows on account of the welfare programmes have remained a fastest growing expenditure in budget of India and the supply of rice under subsidy scheme happened to be the largest of these programmes in terms of costs (World Bank, 1987).

We introduce hSOs: hierarchical semantics of objects. An hSO is learnt from a collection of images taken from a particular scene category. The hSO captures the interactions between the objects that tend to co-occur in the scene, and hence are potentially semantically related. Such relationships are typically hierarchical. For example, in a collection of images taken in a living room scene, the TV, DVD player and coffee-table co-occur frequently. The TV and the DVD player are more closely related to each other than the coffee table, and this can be learnt from the fact that the two are located at similar relative locations across images, while the coffee table is somewhat arbitrarily placed. The goal of this paper is to learn this hierarchy that characterizes the scene. The proposed approach, being entirely unsupervised, can detect the parts of the images that belong to the foreground objects, cluster these parts to represent objects, and provide an understanding of the scene by hierarchically clustering these objects in a semantically meaningful way - all from a collection of unlabeled images of a particular scene category. In addition to providing the semantic layout of the scene, learnt hSOs can have several useful applications such as compact scene representation for scene category classification and providing context for enhanced object detection.


According to the working principle and service condition of new type screwing-urn compressor,two kinds of alloy cast iron rubbing-pair material with different components were designed and the properties of the materials were tested.Phosphorus eutectic and carbon compound with boracium were found in the structure of rubbing-pair material when reasonable amounts of the elements of phosphorus and boracium were added.The results show that the addition can obviously improve or increase the friction and wear behavior of the rubbing-pair materials.The rubbing-pair materials with higher amount of phosphorus possess excellent comprehensive properties that can satisfy the usage request of the new type screwing-urn compressor.


According to the general introduction of some self-anchored suspension bridge and the introduction on technological standards,the paper illustrates the stressed performance and design points for the suspension bridge,and analyzes the technological points for the engineering,so as to accumulate experience for the design and construction of concrete self-anchored suspension bridge of single tower in similar condition.


The dual mobility (DM) bearing concept was introduced to reduce the risk of dislocation in total hip arthroplasty (THA). Our aim was to evaluate the early outcomes following the utilisation of DM in primary and revision THA in our unit. Prospectively collected data on all patients undergoing a DM bearing at was reviewed between July 2012and December 2015. The primary outcome assessed was dislocation, with a secondary outcome revision for any reasons. All data was gathered from patient clinical records and the digital picture archiving and communication system (PACS) 30 primary THA were undertaken and 54 revision THAin the time period described. 11 of the procedures involved a proximal femoral endoprosthesis. The mean age in the primary setting was 65 and 73 in the revision population. The main indications for using DM bearing in the primary setting were; trauma (40%), residual dysplasia (40%) and malignancy (17%). There were no dislocations in the primary THA category. Indications in the revision THA cohort included 33% for aseptic loosening, 11% for instability, 18% for ALVAL reactions, 20% for infection, 18% for fracture. 1 out of the 54 revision THA had one large bearing dislocation requiring closed reduction. Subsequent analysis confirmed that implant alignment was satisfactory and this was a patient compliance issue due to mental health concerns. To date no patient in either cohort required revision surgery. Overall dislocation rate was 1.2%. Our early experience with DM bearings has been positive with no evidence of early failure or loosening. The dislocation rate overall has been low and matches the current large series in the literature.


Abstract Xenotransplantation of hepatocytes appears to be a novel promising therapy for some forms of liver disease, and may well overcome the problem of donor shortage. We have previously reported that hepatocytes with a spheroidal shape (spheroids) are ideal for cell transplantation. The application of gene transfer techniques to this hepatocyte transplantation could possibly regulate the xenogeneic rejection reaction and, therefore, result in prolongation of the survival of the transplanted hepatocytes. In this study, we chose the adenovirus as a vector and an immunosuppressive cytokine named viral IL‐10 (vIL‐10) for transfection. A series of experiments was performed to elucidate the efficacy of transfection to the spheroids with adenovirus vectors and the effect of transfected vIL‐10 on the survival of xenogeneic hepatocytes. We examined the cell survival quantitatively by evaluating β‐galactosidase (β‐gal) activity, which was transfected into the hepatocytes in the xenogeneic spleen, and semi‐quantitatively by the histological findings. The results of in‐vitro studies identified an efficient expression of the β‐gal gene within the spheroids infected with Ad‐CMVLacZ (LacZ‐encoding adenovirus vector with CMV promotor) and the presence of BCRF1 mRNA within the spheroids transfected with AdCMVvIL‐10 (vIL‐10‐expressing adenovirus vector with CMV promotor) under the condition of 1 MOI, for 1 h. Xenogeneic hepatocytes with a spheroidal shape showed comparable survival to syngeneic hepatocytes for up to 4 days after transplantation with co‐transplantation of the vIL‐10‐transfected hepatocytes. From this study, we concluded that adenovirus‐mediated vIL‐10 gene transfer prolongs the survival of xenogeneic hepatocyte spheroids. Furthermore, spheroids possess ideal properties for gene transfection, as well as cell transplantation.


The present work deals with the problem of increasing the natural frequencies and hence the critical speeds of a rotating disk by inserting thin radial stiffeners into the disk. Introduction of such stiffeners of higher strength and rigidity though does not affect the properties and performance of the disk reasonably, according to the present analysis it is found that they can successfully increase the natural frequencies of the disk, both in static as well as rotating conditions. Using the FEM software Ansys 8.0, modal analyses of the rotating annular disk with radial stiffeners of different geometries were performed. A gradual development of the stiffener geometry on the basis of conclusions drawn from intermediate results finally yielded a stiffener, which could successfully push up the modal frequencies, and hence potentially increase the critical speeds of the disk. In an analytical approach to the problem, though it was rather difficult to incorporate the stiffener geometry, some elementary analyses were performed and after a thorough mathematical investigation, a partial differential equation was set to describe the vibration of the disk with stiffeners. However a final analytical solution could not be achieved at the present moment due to the complexity of the equation.


In this paper, we consider the properties of a Leslie–Gower predator–prey system under two basic assumptions that the prey growth is affected by an addictive Allee effect, and the intrinsic growth rate of prey is much bigger than that of predator. Using the geometric singular perturbation theory and blow up technique, we show that this system can have rich dynamics, such as subcritical Hopf bifurcation, canard explosion and relaxation oscillations. Numerical simulations are also carried out to validate our analytical results.

Results of theoretical evaluations of uncertainties arising from the atom-lattice interaction effects on the clock frequency are presented for Sr atoms. Possibilities for simultaneous tuning of optical lattice frequency and intensity parameters are discussed aiming at minimizing uncertainties induced by interaction of Sr atoms with the field of magic-wavelength optical lattice. The fractional contributions to the clock-frequency shift from the spontaneous emission of the lattice-beam amplifier after having passed the optical fiber are determined at the level below 10−18.


taught at Columbia University, the University of Nebraska Omaha, and Boston College's School of Theology and Ministry. The book concentrates on the French missionary work of the seventeenth century—sources for that period are richer than those for the later periods. Nonetheless, it also covers development well into the eighteenth century. The book is divided into two parts: the first focused on the missions' founding era and early decades of its development and the second part highlights the issues of continual warfare and metropolitan neglect as these shaped the Jesuit enterprise. Part I focuses on the mission's founding, from 1610s to 1660s, and shows that missionaries under the leadership of Paule Le Jeune, François-Joseph Le Mercier and others who acted closely with French political and mercantile elites, particularly in the period of Cardinal Richelieu's administration. French authorities in France and Canada decided to utilize the Jesuit access to the Native nations to help negotiate trade and military alliances for New France. The author demonstrates how the Jesuits contributed to the transformation of the woodlands and indigenous villages into secure and economically productive trade centers characterized by military preparedness. Part II covers the late seventeenth and eighteenth century, during which different political, social, and cultural realities shaped the French colonial world, a period that spans from the beginning of Jean-Baptiste Colbert's ministry (1661) to the end of the Seven Years' War in 1763 when dreams of a French empire dissipated. During these years, the shift in metropolitan politics to Versailles and the decrease in interest in the colony resulted in diminished support (supplies and guidance) for Jesuit, suffocating imperial aspirations. As a result, the Jesuits "moderated their ambitions for a French Catholic empire in America, due more to metropolitan neglect than Native American resistance or English advances" (p. xviii). Although the book also deals extensively with the role of the Jesuits in the territorialization of New France (their role in negotiating peace treaties and demarcations is particularly well documented), their role in exploration in this study is somehow left behind. Exploration and mapping by the Jesuits were equally important for the establishment of French power and the economic prosperity of the colony. Yet, the book provides an excellent contextualization of the policies pursued in Paris and Quebec, which determined the fate of the Jesuits not only in their missionary work, but also in their exploration. The book represents a valuable contribution to French colonial history and transatlantic cultural and intellectual exchange, as well as to a better understanding of French influence on the development of modern American society in general.


E-procurement is a popular enterprise information systems (EISs) that were implementing by many companies and governments in digital transformation era. E-procurement for the tendering process increases transparency and organizational performance. The objective of this paper is to utilize the web mining to gain insight from data patterns in e-procurement systems regarding procurement performance. Construction tender data from two central provinces in Indonesia: East Java and DKI Jakarta, are case studies to be absorbed from tender applications via web mining. The case studies data are processed using the multiple linear regression method to produce a predictive model for one of the effectiveness performance indicators: bidder appointment time. Four independent variables: contract price, number of participants, number of bidders, and number of revisions were proven to predict bidder appointment time significantly. The number of revisions has the most influence on bidder appointment time in terms of its coefficient value. The model can be used for tender scheduling, setting procurement targets, to resource planning.


The interaction between a probe and a plasma has been studied since the 1920s and the pioneering work of Mott-Smith and Langmuir [1], and is still today an active topic of experimental and theoretical research. Indeed an understanding of the current collection process by an electrode is relevant to diverse matters such as Langmuir and Mach-probes calibrations, dusty plasma physics, or spacecraft charging. Recent simulations relying on the ad hoc designed code SCEPTIC have fully addressed the collisionless and unmagnetized problem for a drifting collector idealized as a sphere. SCEPTIC is a 2d/3v hybrid Particle In Cell (PIC) code, in which the ion motion is fully resolved, while the electrons are treated as a Boltzmann distributed fluid [2, 3]. In the present work we tackle the transition between the unmagnetized and the weakly magnetized regime of ion collection by a spherical probe (The mean ion Larmor radius rL ≥ rp) in a collisionless plasma (The ion mean free path λmfp rp). When the sphere is at space potential, we demonstrate that the ion current dependence on the background magnetic field B is linear for low B, and provide analytical expressions for this dependence. When the probe potential can not be neglected, the problem shows two distinct scale lengths: A collisionless layer of a few rp close to the probe, followed by a collisional presheath of a few λmfp. The chosen approach is to resolve the collisionless scale-length with SCEPTIC, while using appropriate outer boundary conditions on the potential and ion distribution function to connect with the unresolved collisional presheath. We present results of our numerical simulations for a wide range of plasma parameters of direct relevance to Langmuir and Mach-probes. Thesis Supervisor: Ian H.

Teaching is considered to be the noblest of all the profession. It is termed as the profession of the prophets. A person serving in any profession must have aptitude and competence in his profession. Aptitude of teachers towards teaching may be considered the most important factor, which may predict the success in that profession. Thus, the investigator felt to make an attempt to assess the aptitude of high school teachers' towards teaching in relation to some demographic variables i.e. gender and educational level. For that Teaching Aptitude Test Battery (TATB) developed by Shamim Karim and Ashok Kumar Dixit is administered to a sample of 120 teachers of 12 provincialised high schools of Kamrup District of Assam. The findings are (i) Except optimistic attitude, mean score of teaching aptitude of high school teachers in all categories is very high; (ii) there exists no significant difference in the mean scores of teaching aptitude of the male and female teachers of high school and (iii) there exists no significant difference in the mean scores of teaching aptitude of the graduate and post graduate teachers of high school.

Then based upon a finished Earthquake Disaster Reduction System, redevelopment of the system skeleton is well discussed, including technical skeleton, function composition, structure of software and hardware, redevelopment languages, databases, and remote linking and calling of analysis modules. Finally this paper presents that extending and utilizing the function of remote sensing information on the basis of the current distributed Earthquake Disaster Reduction System Skeleton would become a new trendency on the field of Earthquake Disaster Reduction System.


Self-incompatibility is adopted by many flowering plants to prevent inbreeding, and is controlled by a multi-allelic \(S\)-locus. In \(Papaver\) \(rhoeas\), the pistil \(S\)-determinant is PrsS (a small secreted protein); the pollen \(S\)-determinant is PrpS (a novel transmembrane protein). Cognate PrpS-PrsS interaction induces DEVDase-mediated programmed cell death of incompatible pollen. Here, we examined the role of proteasome during the \(Papaver\) SI response and showed that the proteasome is a target of the \(Papaver\) SI response, and is distinct from the SI-induced DEVDase activity.
Our main focus here is translational work, attempting to move the Papaver SI system into \(A\). \(thaliana\). We previously demonstrated that PrpS:GFP expressed in \(A\). \(thaliana\) pollen was functional \(in\) \(vitro\). Here, we expressed the female \(S\)-determinant, PrsS, in \(A\). \(thaliana\) and investigated function \(in\) \(vivo\). We present data demonstrating that transgenic A. thaliana stigmas expressing PrsS pollinated with \(A\). \(thaliana\) pollen expressing PrpS:GFP inhibited pollen tube growth in an S-specific manner, and virtually no seed was set. Transformation of both \(PrpS\)\(:\)\(GFP\) and \(PrsS\) into \(A\). \(thaliana\) generated self-incompatible plants that set no self-seed. This demonstrates that transfer of the \(Papaver\) SI system into a highly diverged self-compatible species can result in a fully functional SI system.


Although high resolution isotropic 3D medical images are desired in clinical practice, their acquisition is not always feasible. Instead, lower resolution images are upsampled to higher resolution using conventional interpolation methods. Sophisticated learning-based super-resolution approaches are frequently unavailable in clinical setting, because such methods require training with high-resolution isotropic examples. To address this issue, we propose a learning-based super-resolution approach that can be trained using solely anisotropic images, i.e. without high-resolution ground truth data. The method exploits the latent space, generated by autoencoders trained on anisotropic images, to increase spatial resolution in low-resolution images. The method was trained and evaluated using 100 publicly available cardiac cine MR scans from the Automated Cardiac Diagnosis Challenge (ACDC). The quantitative results show that the proposed method performs better than conventional interpolation methods. Furthermore, the qualitative results indicate that especially finer cardiac structures are synthesized with high quality. The method has the potential to be applied to other anatomies and modalities and can be easily applied to any 3D anisotropic medical image dataset.


The model of machining process was set up,and the parameters of the PID controller for the model were optimized via the GA in this paper.The simulation experiment proved that the control system with optimized parameters had good dynamic performance.


A mild and efficient method for the synthesis of chromenonaphthyridine derivatives via domino reaction of aminopyridine and different O-propargylated salicylaldehydes using CuI/InCl3 as an efficient catalyst, refluxed in acetonitrile is reported. Mild reaction condition, operational simplicity, good to excellent yield and easy isolation of product is the silent feature of this reaction. INTRODUCTION Heterocycles are omnipresent in nature and possess important biological and pharmacological activities. They represent many core structures of pharmaceutically important molecules. Naphthyridine derivatives are one of the most important classes of such compounds. Recently synthesis of different heterocyclic compounds including naphthyridine moiety has been reported, as they have potent pharmaceutical as well as excellent biological activity.1 Several naphthyridines derivatives display antibacterial activity,2 medicinal use in cardiac insufficiencies and infarction,3 anticonvulsant activity,4 anti-human cytomegalovirus (HCMV) inhibitors,5 and anticancer activity.6 The development of eco-friendly process in terms of sustainable chemistry has become a focal point in chemical research in recent years. The hetero Diels-Alder reaction is one of the most efficient and powerful synthetic tool for the synthesis of heterocycles.7 Recently various transition metal salts8 is used as catalyst in hetero Diels-Alder reaction among which copper and indium trichloride have been extensively used in organic synthesis. Both copper and indium chloride have gained a considerable attention in organic synthesis due to their commercial availability, stable in air, inexpensive and non-toxic nature. Moreover copper can easily activate the terminal alkyne9 bond and indium trichloride coordinate with imine double bond and facilitate in cyclization through hetero Diels-Alder reaction. So many reports are available in the literature of indium trichloride as a green and potentially Lewis acid catalyst to HETEROCYCLES, Vol. 96, No. 1, 2018 43

Medical missionary and former health minister Tanzania (b 1906; q the London Hospital 1929; FRCS (hon)), d 7 February 2003.

Leader Dominic Stirling arrived in what was then Tanganyika in 1935 as a medical missionary. After a short period working in Masasi he moved to a more remote area to design and build his first hospital. He dealt with surgical emergencies of all types and designed an operation for elephantiasis of the scrotum. After 14 years he moved to another area, where he again designed and built a hospital, which is still in use today. He was the first doctor in Tanzania to start nurse training. His final move was to the slopes of Kilimanjaro, where he supervised the building of yet another hospital. He was an MP from before independence in 1961 until 1983, and at the age of 70 he became Tanzania's minister of health for six years. He leaves his second wife, Annah Chisonga.


This article represents the second part of a review by De Stefano and Vasilyev (2021) on wavelet-based adaptive methods for modeling and simulation of turbulent flows. Unlike the hierarchical adaptive eddy-capturing approach, described in the first part and devoted to high-fidelity modeling of incompressible flows, this companion paper focuses on the adaptive eddy-resolving framework for compressible flows in complex geometries, which also includes model-form adaptation from low to high fidelity models. A hierarchy of wavelet-based eddy-resolving methods of different fidelity has been developed for different speed regimes, various boundary conditions, and Reynolds numbers. Solutions of various fidelity are achieved using a range of modeling approaches from unsteady Reynolds-averaged Navier–Stokes simulation to delayed detached eddy simulation, wall-modeled and wall-resolved large eddy simulations. These novel methodologies open the door to construct a hierarchical approach for simulation of compressible flows covering the whole range of possibilities, from only resolving the average or dominant frequency, to capturing the intermittency of turbulence eddies, and to directly simulating the full turbulence spectrum. The generalized hierarchical wavelet-based adaptive eddy-resolving approach, once fully integrated into a single inherently interconnected simulation, results in being a very competitive and predictive tool for complicated flows in industrial design and analysis with high efficiency and accuracy.


The authors propose a correlation between certain elements of Neolithic material culture — painted pottery and anthropomorphic figurines — and Y-chromosome haplotypes, suggesting a shared history of dispersal of human populations and cultural ideas.


In the course of the ongoing debate regarding the critique of the German Riester pension the Swedish premium pension has often been referred to as a role model regarding potential amendments and reforms. The Swedish pension reform of 1998 has led to a reorganization towards a stratified scheme, consisting of a pay-as-you-go and a fully funded element. The mandatory implementation of the Swedish premium pension has proved to be the major difference in comparison to the voluntary German Riester pension. In addition, numerous differences between the two systems can be outlined, of which most are due to the differing methods of implementation in the country's old age provision system. This paper draws a comparison between the two systems with a special focus on the cost structure and evaluates the possibilities and limitations that arise from a complete adaptation of the Swedish premium pension (German premium pension) as well as a partial modification of the existing Riester scheme (Swedish-Riester). It becomes evident that costs are significantly lower in the Swedish system thanks to a rebate system and the centralization of administrative tasks within the Swedish Pensions Agency. However, despite systematic differences between the two schemes, the German Riester pension can particularly benefit from the Swedish premium pension with regard to transparent, coherent and consistent product information.

Therapy was highly successful using both body acupuncture and acupuncture of the ear in illnesses ranging from cervical, thoracic and lumbar syndromes, gonarthritis coxarthritis, rhizarthritis, periarthritis of the shoulder, epicondylitis humer radialis, tendonitis, fibromyalgia and polyarthritis, Morbus Bechterew, paresis after strokes, migraine and other headache-syndromes, Tinnitus, trigeminal neuralgia, gastropathy, bronchial asthma, AVD, depression and other psycho-vegetative burn-out syndromes. Treatment was made by simultaneously using 8 Laserneedles, which were not pricked into, but adhered to the skin. The Laserneedles emit red and infrared laser rays with a high-energy output, so that perceptible, vegetative stimulation can be detected at the sites of the acupunctured areas. We found out that especially in the therapy resistant, long standing cases and those with chronic backand spinal problems considerable improvements in easing pain and increasing mobility could be made. Recognizable success was made by using Laserneedles in cases suffering from psychological illnesses, especially psychosomatic related Burnout-Syndrome and cases of exhaustion. Usually after 2-3 treatments sufficient success was made, without any side effects.


In this paper, a genetic algorithm-based approach for transient analysis of single-conductor overhead line connected to grounded arrester is proposed. In analysis, the grounding systems are buried in lossy dispersive soil, i.e., the electrical parameters of soil are frequency-dependent. In dealing with the problem, the lightning current pulse is first approximated by a finite set of sinusoidal harmonies in a time domain. Norton equivalent circuit viewed across the arrester is then computed via transmission line model (TLM). Finally analyzing this nonlinear circuit by genetic algorithm, transient voltage across the arrester is easily computed. Comparison of the achieved transient voltages with and without considering dispersion of soil shows that this effect plays an important role in selecting lightning arresters and the insulation coordination study of power systems. Moreover, in comparison with arithmetic operator method (AOM), the run-time is reduced.

Because of its far reaching consequences on income, inequality and welfare, a large economic literature has attempted to uncover the determinants of parental investment in children human capital. So far, most studies in this literature have focused on children characteristics to explain inequalities in parental investment among siblings. As a complement to this mainstream, I investigate whether or not existing beliefs about children' value affect how parents allocate resource among siblings. To test this hypothesis, I use the case of twins which are venerated and worshiped as deities in several parts of Africa. Based on Demographic and Health Survey (DHS) data from Benin, I find a twins preferential treatment in parental investment in children health. As this result survives various robustness checks and competing explanations, I explore its underlying mechanisms and speculate on whether it should be interpreted as a behavioral anomaly or as the outcome of a neo-classical cost-benefit calculus.

An in situ fluorometer capable of operation to 400 m is described. A pulsed xenon light source ensures low power consumption (6 W) and a high signal-to-noise ratio, giving a phytoplankton chlorophyll a detection limit of 0.1 mg/m3. Operation at 8 knots in an undulator enables vertical profiles to be determined with a resolution of about 1 m. By changing the optical filters it is possible to detect the fluorescence of dyes, hydrocarbons, carbosol, etc., with similar high sensitivity.


The aim of the paper is to study how it's possible to enhance the cognitive enterprise model by the theory of autopoietic systems. I propose a model that considers the organization as a closed system in which all cognitive activity is necessary to develop coherent operations needed to adapt the firm to environmental perturbations. The central issue of the work consists in the presentation and description of the "chain thinking-action" as a cognitive basis that builds models from which derive the actions that characterize the transformation of a business enterprise in order to maintain the viability over time. A "winning" entrepreneurial thinking is able to give a direction (objectives-strategy) always aimed at improving the organization's vital parameters. The role of entrepreneurship and management, therefore, is to create the conditions to encourage a continuous development of cognitive models in organizations, in order to maintain the conditions of survival and to lead the company in a situation of evolution and improvement.


Background: Malnutrition and iron deficiency anaemia are quite prevalent in developing countries. Aims: To assess the frequency of iron deficiency anaemia among malnourished children in suburban population of Lahore, to identify the underlying etiological factors of iron deficiency anaemia in children under 5 years and to make recommendation for iron supplementation in children at school or Basic health unit. Study Design: A descriptive analytical study Settings: This study was conducted at Pediatric Department Punjab Social Security Hospital, Lahore Study Period: Jan2018 to June-2018. Methods: All children presenting in hospital from 6 months to 5years presenting to OPD/Emergency department (Normal-malnourished) were enrolled in study. They were divided into two groups, malnourished and wellnourished based on WHO growth charts (Z-score types). Thalassemic children were excluded from the study. Children were examined and investigated as per protocol to establish iron deficiency anaemia. All necessary information were noted on proforma. Children with hemoglobin level less than 11gm/dl were considered as anaemic. All anaemic children were treated by iron supplements. Results: Data were analyzed by computer-based software and results were analyzed using chi square test. Results were considered as significant if p-values is less than 0.05. Conclusion: Iron deficiency anaemia is as common in well-nourished children as in malnourished children although underlying etiology may be quite variable. Poverty, illiteracy, maternal food fad and careless attitude were main underlying causes in our study. Universal iron fortification(flour) and regular iron supplementation to children through basic health units and school health services should be done on regular basis to correct the iron deficiency anaemia and related health problems.


This paper contributes to the debate following the British Psychoanalytic Council's 2012 conference, 'Homosexuality and Psychoanalysis: Moving On' and their Position Statement on Homosexuality. After two world wars psychoanalysts, concerned to establish the credentials of their discipline, sought a more settled definition of sexual 'normality' than that of Freud, which 'naturalized' a heterosexual view of gender difference. Extending one aspect of Freud's thinking, homosexuality became accepted as evidence of a developmental retreat, even as a fixation at the oral stage of relating. As an identity founded on rejection of the reproductive 'reality' of the body, it was seen as a borderline condition. An individual who did not regard it as a problem to be cured was understood to be maintaining a perverse denial of their pathology. Same sex object-choice was narcissistic and led to the formation of unstable patterns of relating. In this paper I hope to show that psychoanalysis has in the past developed a theoretical bias that has distorted its view of the experience of lesbians and gay men and, in detecting and questioning this bias, we have an opportunity to make our discipline more open and responsive to the complex society we live in.

Hydrogenation of aromatic rings promoted by earth-abundant metal composites under mild conditions is an attractive and challenging subject in the long term.


Oak Ridge National Laboratory conducted field radiological measurements at two port locations at the request of the Environmental Protection Agency (EPA). The radiological measurements were performed on five radiation detection systems at the port of Darrow, Louisiana and three systems at the port of Charleston, South Carolina. Darrow was visited on January 20-23, 2004 and Charleston on May 25, 2004. All tested systems are designed to detect radioactive material that might be present in scrap metals as the scrap is being unloaded from ships. All eight systems are commercially known as the Cricket and manufactured by RAD/COMM Systems. Each radiation detection system consists of a detector with two channels and a wireless transmitter, both mounted on the grapple, and a controller located in the crane cab. The cranes at both locations are operated by the Cooper T. Smith Company. The purpose of the radiological measurements was to evaluate the performance of the radiation detection systems in terms of their ability to detect elevated radiation levels, and to develop a routine testing method for all EPA Cricket systems.


Should events such as the Tvashar fire fountain be expected? Examination of the Galileo Near Infrared Mapping Spectrometer (NIMS) C3 data set shows that the chances of observing some level of active volcanism in any given area covering at least 135 km(exp 2) is quite reasonable.


Digital speckle correlation method(DSCM) is used to measure the thermomechanical coupling effect in COB packaging structures.The CCD camera is applied to capture the speckle patterns of CMOS chip at different temperature fields.by analyzing the speckle patterns,the in-plane deformation of the CMOS chip is obtained.Based on the trigonometrical theory,the out-plane displacement can be obtained by measuring the in-plane displacement,and then the elasticity thermal stress of the chip is evaluated when the application of the temperature field is repeated.The experiment results agree well with that of FEM simulations and the theoretical model.It is proved that DSCM can successfully be applied to the analysis of the thermomechanical coupling effect.The theoretical model is also verified by the result of FEM simulations and experimental testing.The experiment results provide a availability reference to the design of MEMS aparatus.


Some 100 years before Albert Munsell developed his color order system, French silk merchant and inventor of a technology for producing works of art in silk velours, Gaspard Gregoire, introduced a color order system based on the color attributes hue, (relative) chroma, and lightness. Conceived in the mid-1780s, an atlas with 1350 samples was produced before 1813 and found use in French Royal manufacturing operations and educational institutions. It was followed a few years later by one with 343 samples. Gregoire's work was subsequently overshadowed by Michel-Eugene Chevreul's more complicated and less intuitive hemispherical system of 1839. © 2007 Wiley Periodicals, Inc.

In view of the findings, some recommendations were offered.


Human Capital has been examined in several countries. Financial statement users require information to hit an asset because it is important. However, in another hand, it is frequently to be ignored. Financial statement of human resources is supposed to get rendered in deep numeral. However, there is a problem of it. The problem is that making financial statement for intangible assets is not easy. Accounting scholars are dealing with new challenges on how to report this human resource capability proportionately and informatively to ensure the users of financial statement in order to get informed pretty well. Accounting conventionally treats expenditures for human resources as expense. Even the terminological character of the expenditures are kind of its unmitigated constitute human capital forming (human capital). By pinching it necessarily in capitalization accounting is treated to engage cost or value of human resources. This amends as human resource accounting or human resource accounting ( HRA ). This paper is aimed to discuss this issue by using the concept of human capital as an approach. The conclusion of this research is that the disclosure of the information in financial statement is the most possible way to be taken.


Time series on Crangon crangon densities in the German Wadden Sea show a considerable degree of interannual variability, for the entire region in spring and in autumn as well as for three subareas, North Frisia, East Frisia and Elbe estuary. Across the entire survey area C. crangon density was inversely related to water depth. In autumn after the recruitment, settlement shrimp densities are correlated across a larger spatial scale (>100 km longshore), whereas in spring the overwintering adult spawning stock is uncorrelated across subareas. Interannually, extreme density variations can develop even over a short time span of 1 yr. On a large spatial scale shrimp abundance in autumn was correlated with year-to-year changes in physical environmental and biological parameters, winter water temperature, autumn river runoff and the winter NAO index. On a regional scale (North Frisia), density of gadoid predators was an additional component affecting shrimp stock abundance. No correlations to such parameters could be detected for the C. crangon stock in spring. Possible causes for the spring situation and additional sources for variability are discussed.


The recent progress of study on "Pectoral Limb Shiver"disease in Chinese mitten crab is reviewed in this paper,a new poly pathogeny view is also put forwarded,and the author also prospected the study on this disease in the future.


We discuss estimates of stellar temperature, and the assemblage of a "critical set" of target low-metallicity stars, from the HK Survey of Beers and collaborators, that can be used in the near future to put additional strong constraints on models for lithium production in the early Galaxy, and for inference of its primordial value.


Coronary-pulmonary fistulas are rare. The majority of these fistulas arise from the left anterior descending or the right coronary arteries; the circumflex coronary artery is rarely involved. The majority of patients are asymptomatic, but heart failure, angina, myocardial infarction, endo carditis, and dyspnea have rarely been reported. The management is controversial and recom mendations are based on anecdotal cases or very small retrospective series. A case of a 62- year-old female is reported who presented with chest pain and was found to have myocardial ischemia on SPECT sestamibi. Cardiac catheterization revealed no obstructive coronary artery disease and a large coronary pulmonary fistula communicating from the left circumflex coronary artery to the left pulmonary artery.

Sentiment analysis is needed because the analysis of the emotion is somehow complicated due to slang phrases, misspellings, short-forms, recurring characters, the use of dialects, and modern emoticons. The aim of this project is to develop a system to analyze the sentiment of movie reviews and visualize the result of sentiment analysis. The dataset was captured from IMDb movie reviews. This dataset contains 50,000 instances with two columns which are the reviews and their sentiments. The data set undergoes a cleaning process to extract meaningful data. Two types of features have been investigated, namely, the Bag of Words (BoW) and the TF-IDF modelling with Naïve Bayes classifiers. The result of accuracy is 89% which indicates that the Naïve Bayes can be used for sentiment analysis in any movie review task.


Shortly after the constitution of this project,in order to verify the feasibility of the theoretical research implementation,we proposed an additional requirement of direct involving in the production of oil and gas reservoirs in the outer part and deep part of Daqing,so that the overall merit of both theoretical research and practical application of this project can be improved.With the successful construction of PC-clusters and development of the seismic data parallel processing system plus assistant software packages in 1998,we built up the 3D wave equation pre-stack depth migration algorithm and the corresponding software in 2000,which is synchronous with international seismic exploration community.Such an achievement greatly improves the capability of seismic imaging in China.In the year of 1999,we assembled an eight-node PC-cluster and processed 150 km-long seismic profiles.In paticular,on the depth map of line 82,we clearly imaged the internal structure and fault character of an uplift in a depression area.After a rearrangement of 3D seismic exploration and with many research works,a great break through was achieved accomanying the drilling of the Xushen No.1 well and leading to the discovery of the huge gas field in Daqing.This success remarkably improves the continuable development foreground of Daqing oilfield.We have also built up two reservoir geophysics research centers in Beijing and Daqing,respectively.It has been proved that proper and reasonable research organization and activity will benefit the integration and application of the products of a great scientific project,and is key to make progress with combined efforts consecutively and efficiently.


eustenance by sucklng out the juices of its victim, and never even relaxed its hold in death. In those days It was an animal.I1 is probable that at a later date it presented itself to our forefathers rather as a vegetable, and the terms fungous, fungating, and the like, denoted certain conditions of cancer. The likeness of morbid new growths to some of the large parasitic tumours of plants and trees also tended to encourage the belief in the parasitic origin of cancer. The moulds which attack and infiltrate the tissues and organs of certain insects and the larva of insects, and gradually replace them, although their form may still be maintained and distinguished, remind us of those cases of cancer in which the walls of hollow organs, such as the stomach, although infiltrated and thickened by the disease, still retain their form as walls. The resemblance of cancerous masses to the masses formed In specific, tuberculous, and other diseases which we now recognize under the general term, the infective tumoursa resemblance so close that it is sometimes impossible to distinguish between cancerous and infective masses-provides another reason for the belief in the parasitic nature of cancer.. And the disposition of the secondary growths in the two kinds of disease lends still further colour to the theory. And there are certain parasitic diseases of fish, of the barbel and the pike especially, in which the tumours are almost entirely made up of myxo-sporidia, and in which the resemblance to malignant disease Is so striking that it Is almost impossible to believe that they are not cancerous. It would be easy to multiply reasons, some of them wholly fantastical, some quite sound, for regarding cancer as a parasitic disease, or, at least, as a disease due to the presence or influence of parasites.

Cerium oxide nanoparticles are promising materials as novel nanoscale therapeutics and are commonly used materials in industrial processes. Most cytotoxicity studies on cerium oxide nanoparticles are made from in-lab prepared materials making comparison between studies challenging, especially when performed on unique cell lines under non-standard conditions. Using commercially available nanoparticles we show that particle stability/agglomeration may be critical in determining the cytotoxicity in some cell lines, while in other cell lines, larger sized primary particles are linked to higher cytotoxicity, contrasting what has been reported in the literature for smaller cerium nanoparticles. To accelerate the development of cerium oxide enabled commercial processes and biomedical innovations, a clearer understanding of the interactions between cerium oxide nanoparticles and cells is needed to better understand their fate in and impact on biological systems.


The sand storm dust adheres to the crops' leaves,has obvious negative influences to crops' Pn,Tr,Gs and respiration,and even causes the crop output to drop finally.The paper presented gas exchanges on three traditional crops in Minqin.It mainly solved the dust capacity of leaves influence on respiration rate of different crops as well as the different period of duration,the different position of leaves to respiration influence.The results showed that(1)The rate of net photosynthetic rate(Pn),transpiration rate(Tr),stomatal conductance(Gs) of cotton were higher than other two species,indicating smaller loss rate of gas exchange parameters but higher adaptability to storm dust environment for wheat and corn;(2)Correlation analysis showed a remarkable negative correlation between rate of respiration rate and amount of dust detained;(3)The respiration rate with dust born leaves and clean leaves under different period and heights were extremely significant(P0.01).


Objective To investigate the CYP1A1 gene Ile-Val and Msp1 polymorphism and relationship with susceptibility of colorectal cacer.Methods Ile-Val and Msp1 polymorphism of CYP1A1 were detected in 79 cases of colorectal cancer and 110 cases of control by PCR-RFLP and AS-PCR.Results The frequencied of 7th exon polymorphisms in cancer group and control group were statistically significant differen(P0.05),the distribution value of Ile-Val and Val/Val genotype in cancer group was higher than in control group.The risk of Ile/Val and Val/Val to colorectal cancer was 2.113 and 4.203 times respectively to Ile/Ile genetype.Considering the risk factor of smoking,the risk of colorectal cancer in individual with Ile-Val and Val/Val genotype was 2.980 times of others with Ile/Ile genetype.There was no significant correlation between Msp1 polymorphism and colorectal cancer susceptibility.Conclusion The results suggest that Ile/Val and Val/Val genotypes are related to the susceptibility of colorectal cancer,they might be one of the risk factors of colorectal cancer.The results do not show that polymorphism of Msp1 is associated with susceptibility of colorectal cancer.


The W-type Barium hexaferrite particle have been successfully synthesized by mechanical milling route. The formation of phase BaFe16Co2O27 through two-stage mechanism which starts with the formation of BaFe19O19. The synthetic result is tested by X-ray Diffraction (Cu(Kα) to determine a structure and formation phase. The magnetic characteristic is tested by permeagraph in saturating field up to 1.5 Tesla. The synthetic result shows that the partial substitution of Fe2+ ions with Co2+ ions influence the change in magnetic properties particularly coercivity. W-hexaferrite has a promising potential in microwave absorption application in the future especially in the range at 8 Ghz to 9,0 GHz.

ABSTRACT I am familiar with the fact that it is expected that the general address on surgery read to this Association shall be a resume of the advances made in each and every department of the science and art of surgery, since the previous meeting. To have gone over this entire field would have consumed more of your valuable time than you would like to grant, and involved a task too burdensome for me to undertake. I, therefore, determined to select some single subject for my address. I was then confronted by the fact that every single subject of importance would be fully discussed in the section on surgery; hence I was embarassed in selecting one, for the reason that I wished to edify rather than fatigue you. This, then, was the rub. Having confined myself for fifteen years to a special line of practice, it occurred to me that it


The topology of brokers is very important in a global service-oriented utility grid for serving both the users' and service providers' interests. A three level broker framework is proposed in this paper in which the brokers are not bound to any particular domain. Hence the users and service providers are free to choose the broker they wish. The framework is designed in such a way that the brokers are organized into three levels. A Level 1(L1) broker is assisted by many Level 2(L2) brokers and a L2 broker may be assisted by many Level 3(L3) brokers. Users interact with LI brokers only. L2 brokers are classified according to the type of resources. L3 brokers are classified based on the resources under a L2 broker. A L1 broker contacts L2 brokers, which in turn may contact L3 brokers for selecting the requested resources.


Background With the proposed pathophysiologic mechanism of neurologic injury by SARS COV-2 the frequency of stroke and henceforth the related hospital admissions were expected to rise. In this paper we investigate this presumption by comparing the frequency of admissions of stroke cases in Bangladesh before and during the pandemic. Methods We conducted a retrospective analysis of stroke admissions in a 100-bed stroke unit at the National Institute of Neurosciences and Hospital (NINS&H) which is considerably a large stroke unit. We considered all the admitted cases from the 1st January to the 30th June, 2020. We used Poisson regressions to determine whether statistically significant changes in admission counts can be found before and after 25 March since when there is a surge in COVID-19 infections. Results A total of 1394 stroke patients got admitted during the study period. Half of the patients were older than 60 years, whereas only 2.6% were 30 years old or younger with a male-female ratio of 1.06:1. From January to March, 2020 the mean rate of admission was 302.3 cases per month which dropped to 162.3 cases per month from April to June with an overall reduction of 46.3% in acute stroke admission per month. In those two periods, reductions in average admission per month for ischemic stroke (IST), intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH) and venous stroke (VS) were 45.5%, 37.2%, 71.4% and 39.0%, respectively. Based on weekly data, results of Poisson regressions confirm that the average number of admissions per week dropped significantly during the last three months of the sample period. Further, in the first three months, a total of 22 cases of hyperacute stroke management were done whereas in the last three months there was an 86.4% reduction in the number of hyperacute stroke patients getting reperfusion treatment. Only 38 patients (2.7%) were later found to be RT- PCR for SARS Cov-2 positive based on nasal swab testing. Conclusion Our study revealed more than fifty percent reduction in acute stroke admission during the COVID-19 pandemic. It is still elusive whether the reduction is related to the fear of getting infected by COVID-19 from hospitalization or the overall restriction on public movement and stay-home measures.


Air traffic control is considered to be a bottleneck in European air traffic management. As a result, the performance of the air navigation service providers is critically examined and also used for benchmarking. Using quantitative methods, we investigate which endogenous and exogenous factors affect the performance of air traffic control units on different levels. The methodological discussion is complemented by an empirical analysis. Results may be used to derive recommendations for operators, airspace users, and policymakers. We find that efficiency depends significantly on traffic patterns and the decisions of airspace users, but changes in the airspace structure could also make a significant contribution to performance improvements.

This study focussed on heavy-metal concentrations in sediment off the coast of Kemaman. Sampling was conducted at 21 stations during the pre-monsoon and post-monsoon seasons. Sediment was analysed for total concentration of Co, Pb and Zn using ICP-MS after total acid digestion. The grain size of the sediment samples were measured by dry sieving and using a particle-size analyser. In addition, organic carbon content in the sediment was determined using the wet dichromate-oxidation method. The average concentration of Co, Pb and Zn during the pre-monsoon season was 11.40±3.84 lig/g dry weight, 44.08±33.40 [tg/g dry weight and 254.90±141.02 pg/g dry weight, respectively. The average concentration of Co, Pb and Zn during the post-monsoon season was 10.60±12.66 tig/g dry weight, 17.54±30.79 i.ig/g dry weight and 110.71±58.14 nig dry weight, respectively. Cu, Pb and Zn show poor correlation or negligible relationship with sediment particle size and organic carbon content. This study also found that all the elements have a mainly crustal origin rather than anthropogenic input with Geoaccumulation Index (Ivo) value of less than 1.0 and Enrichment Factors (EF) of 0.69-2.91which suggests minimal-to-moderate enrichment of the metals
