Chemical changes in extractable lipids from four mixtures of farmyard manures were investigated during the composting process. Lipid extractions with diethyl ether (DEE) and chloroform (CHCl3) were sequentially performed on samples collected at seven different times during composting. Amounts of DEE-extractable lipids decreased continuously during composting, while CHCl3-extractable lipids remained relatively constant. 13C NMR and mass spectrometric data indicated that the lipids became chemically more homogeneous during composting and that biologically resistant molecules predominated at the end of composting.


The effect of laser-pulse temporal-profile on the transference of laser energy into the energy of fast ions when the radiation pressure is dominant, has been studied. The laser temporal profiles considered are Lorentzian, hyperbolic secant, and Gaussian. The numerical results are compared for different temporal profile of the laser pulse. It is found that the Lorenztian pulse is more effective to impart kinetic energy to the ions in comparison to Gaussian or hyperbolic secant laser pulse.


This newsletter of the Sao Paulo based Impact Investing Platform that is led by the Latin America Hub of the University of St. Gallen, Switzerland contains a series of five interviews with leading doers and thinkers on Impact Investing in Brazil.

Placed between traditional philanthropy and socially responsible investments (SRIs), Impact Investing offers new opportunities to fuel growth in social enterprises enabling them to enhance the impact they generate. But Impact Investing alone will not solve our social and environmental problems. It can only be one, although important, component and we must stay clear of unrealistic expectations. Furthermore, we face the dilemma that we need more money to fuel growth in social enterprises, but we have to be very selective when it comes to the motivation this money presents itself with.

In RFID system, reader collision happened when multiple readers try to read the tags at the same time. Because reader collision reduces tag recognition performance, it is required for RFID system to have reader anti-collision algorithm. In this paper, we propose reader anti-collision algorithm based on hierarchical structure, where a master reader controls the slave readers to avoid the reader collisions. It is verified through simulations that the proposed algorithm enhances the performance in terms of leader collision probability and tag reading time.


The dynamical behavior of a nanomeniscus is investigated with a oscillating nanoneedle recording information on the change of the shape and viscous contribution. At the air-glycerol interface, the dynamical properties exhibit a nonlinear behavior making the nanomeniscus evolution similar to a first-order phase transition. Also shown is the capability to record height images of the liquid interface with resolutions at nanometer scale. At the air-water interface, evaporation leads to more complex dynamical properties. The viscous damping first increases as a consequence of a thinning effect, then, when the contact angle reaches zero, the nanomeniscus is unable to sustain the dissipation.

The convergence between biology and computer science has not just produced new scientific disciplines such as artificial life, a development, according to some theoriests, of artificial intelligence. It has also produced (and been produced by) a widespread biologization of culture and technology that is exemplified by the attribution of evolutionary mechanisms and metaphors to the human mind and its supposed analogue, the computer and, more specifically, the Internet. Evolution is one of a number of properties of biological systems (alongside self-organization, selfreplication, autonomy and emergence) that has been used to describe the development of the Internet, which is now said to be evolving (spontaneously) into the global brain. What are the ethical implications of naturalizing and therefore dehistoricizing the development of the Internet and other techno-cultural artefacts, and how can we understand this phenomenon? Kember shows how it can only be understood in the context of the convergence between biology and computer science and in relation to disciplines such as artificial life and evolutionary psychology that, in different disguises, initiate a return to sociobiology. Feminism is perhaps in the best and the worst position to engage both critically and constructively with current trends towards evolutionism and sociobiology. The critique was developed in the 1970s but cannot simply be rehearsed because its object has transmuted and effectively assimilated it in a reduced and caricatured form. The rehearsal of feminist arguments is, on its own, futile and a more extensive and nuanced engagement with evolutionary and biological theory is necessary. Ironically, feminists may need to take their lead from internal critiques within biology and come to know the 'enemy' from within.


Republican victories in the US mid-term elections on 2 November are likely to result in attempts to repeal or gut the health reform act passed by the US Congress in March.

In the elections Barack Obama's Democratic party lost control of the House of Representatives but kept control of the Senate. The victors—including members of the Tea Party group, who are nominally Republican but more right wing than the party mainstream—will take office in January, a few weeks after more reforms required by the act take effect.

Repeal of health reform is unlikely, as President Obama can veto such a bill. However, the Senate minority leader Mitch McConnell (Republican, Kentucky) was widely …


This paper is motivated by several recent works studying the mappings of various subclasses of analytic functions by means of certain families of integral operators. The present authors investigate conditions under which some of these integral operators would map starlike and convex functions into the Hardy space H ρ(0 < ρ ≤ ∞) of analytic functions. Some of the main results presented here are also shown to be applicable to certain generalized hypergeometric functions.


A schematic model of over-damped motion is presented which permits one to calculate the mean first passage time for nuclear fission. Its asymptotic value may exceed considerably the lifetime suggested by Kramers rate formula, which applies only to very special, favorable potentials and temperatures. The additional time obtained in the more general case is seen to allow for a considerable increment in the emission of light particles.


Based on the wavefront aberration theory and interferometric theory,the influences of imaging distortion in an interferometer on measuring results are analyzed and calibration and correction methods for the imaging distortion are proposed.The measurement errors caused by misalignments of the test surface(tip/tilt and disfocus) are discussed mainly.An experiment is carried out to measure the same surface under different number of fringes.The test results show that the surface shapes are 30.96 nm PV and 6.32 nm RMS for 3 fringes,and 41.25 nm PV and 8.22 nm RMS for 10 fringes,respectively.After the calibration,the difference of the results are declined to 1.42 nm PV and 0.4 nm RMS.The experiment proves that the calibration solution referred in this paper can improve the measurement accuracy.


thin plate steel destiny has uses requiring a baking step after finishing a stretch as a passage to the press, for example plate cars that improve the properties of remarkable way of saying oven curing (increase yield of the resistance in the oven finishing the heating step) without deterioration of the value (alpha), an index of workability to the press, thus serving to compensate for the reduction in strength caused by the dent weight reduction. The method includes achieving effective composition of Nb and Al, which enables a suitable fixing of C and N in the steel resulting by establishing special conditions of annealing. These conditions make the work of particularly effective Nb.


Bee flies (Diptera: Bombyliidae) are beneficial insects as pollinators or natural enemies of some agricultural pests. The present paper documents 58 species from 26 genera and six subfamilies (Usiinae, Phthiriinae, Toxophorinae, Heterotropinae, Bombyliinae and Anthracinae) from different parts of Iran. This work also includes the details on collection localities and zoogeographical distribution of the collected species.


A new crash box system in the vehicle frontal crash is considering by energy absorbing of the pre-inverted pipe, which is a useful compression force based on the external inversion phenomenon. As a result of the application of the pre-inverted pipe, this paper describes the benefits of the uniform energy absorbing and the space utilization of the crash box systems with 3 thicknesses of pipes during the frontal collision.


To improve the response speed and anti-interference ability of a permanent magnet synchronous motor (PMSM), a PMSM control method based on fractional-order active disturbance rejection control (FOADRC) is proposed in this study. First, a fractional-order tracking differentiator (FOTD) and fractional-order extended state observer (FOESO) are designed using the fractional calculus. According to the response speed of the FOTD and the observation effect of the FOESO, a new fastest function and new nonlinear function are designed. Second, a fractional-order active disturbance rejection (FOADR) controller is built based on the new FOTD, new FOESO, and nonlinear feedback control law, and its stability is proven. Finally, the superiority and effectiveness of the proposed strategy are verified through a simulation and experiments.


This study illustrates how machine learning (ML), deep learning (DL), and anomaly-based techniques can be combined for network intrusion detection. The objective is to improve intrusion detection systems' capability to identify known and novel network threats. While Random Forest is used for classification and feature selection in the ML portion, Convolutional Neural Networks (CNN) capture nuanced spatial patterns in network traffic data in the DL portion. Statistical analysis techniques are used to identify anomalies. Integrating the two approaches, the hybrid method enhances detection accuracy while minimizing false positives. Using real-world datasets, we demonstrate that the proposed method outperforms contemporary machine learning (ML), deep learning (DL), and anomaly-based methods. This hybrid method may greatly facilitate the proactive identification of hazards in the constantly evolving field of intrusion detection. It may be necessary to conduct additional research on optimization strategies and the hybrid model's potential network-wide applicability.


Migration means there is a metabolism cycle in social system,human resources are configured dynamically as commodity under the condition of marketization. Stratum differentiation is always closely related to certain social properties,including the status of the visible population flow. Because of superposition of Stratum differentiation in the static condition and population mobility,social structure is shaped. Since the Reform,social structure of China has changed hugely caused by population mobility with rural migrant workers as the main body,and stratum differentiation which was cast by congenital roles and status by self- efforts at the same time.


The concept model of fire emergency knowledge integration was established based on topic maps by TAO analysis(e.g.basic topic,association type and resource index).Use OKS components,a topic map tool to generate,browse,and visualize some relevant topic maps.This method contributes to improve knowledge systematization and completeness in fire emergency domain,and solve the problem of inconvenient query and difficulty in sharing fire information.


Historically, the majority of virtual storage operating systems have used random virtual page placement. Random placement interacts undesirably with a direct-mapped cache to produce cache conflict misses, some of which could be avoided by making better placement decisions. Recently, several studies on careful page placement as an alternative to random placement have shown that a direct-mapped cache managed with careful placement performs nearly as well as a two-way set-associative cache under random placement. Towards a performance evaluation methodology for careful page placement, we propose two new classes of theoretical page placement policies for direct-mapped caches based on memory reference string lookahead. Lookahead page placement is a systems modeling tool for evaluating nonlookahead policy performance and providing insight into potential gains that might be achieved with improved nonlookahead policies. Strict lookahead policies perform virtual page mappings using only memory reference lookahead information. Hybrid lookahead policies combine existing careful page placement methods with future knowledge obtained through lookahead. Our lookahead policies use greedy, polynomial-time bin selection procedures to assign virtual pages to cache bins having favorable future usage characteristics. Trace-driven simulation is used to compare three different lookahead policies against several nonlookahead page placement policies for three multiprogrammed UNIX workloads.


Based on ten years experiences of the Slovenian Institute for Adult Education the article argues that a national professional institution can take over the role of the main driver promoting the development of adult education. In the period of a thorough economic and social restructuring when adult education is mostly seen and dealt with from the economical point of view, a national professional institution can pursue a much broader approach being more in line with European developments.


This paper examines the problem of choice investment strategies of firms in an oligopoly market. We study the impact of investment strategies of companies on their financial performance and the efficiency of investment under demand uncertainty. A mathematical model for choosing investments in the development of production capacities of companies in competitive oligopolistic markets based on the Nash equilibrium presented, formulated as an optimization problem. Two types of market are considered: a market with elastic demand (Cournot market) and a market with inelastic demand. In the first case, the problem is formulated as a set of interrelated problems of quadratic optimization. To solve this problem, a method of converting the original problem to solving the mixed complementarity problem (MCP) is proposed. In the second case, a method for solving the problem is proposed, based on the joint use of multi-agent modeling and analysis of matrix games. A simulation model was developed that takes into account the relationship between the investments of companies (agents) and market dynamics. A solution of the problem reduced to the analysis of the dynamic bimatrix game, wherein the payoff matrix formed by numerical simulation.


It is commonly thought that the underground economy is larger in Italy than in most other developed countries and that it is growing. Using several methods of measuring it we found no sound support for such view but rather that it fluctuates around a stable mean. We found confirmation of the widespread view of a larger underground economy in the southern regions of the country than in the center-north. We moreover found that the differences between the south and the center-north are not limited to its size but extend to its nature and motivations, thus reaffirming the dualism of the country


In this paper, we have demonstrated a technology for encoding of liquid capped microcapsule and dispensing thousands of heterogeneous encoded liquid drops into microwell array with only a single pipetting step, which would normally requires thousands of individual pipetting. With our technology, we can take advantages of both high coding capacity and liquid-liquid reaction, which is impossible in conventional droplet and bead-based assay platforms.


We have extended a previously reported method immune to random distortion to make it immune to affine transformation as well. Although affine transformation consists of four geometric transformations (scaling, rotation, translation, and shearing), the proposed method requires only scale and rotation searching. Experimental evaluation showed that it can detect each geometric transformation. It can thus be used to create picture watermarks that are immune to a wide variety of geometric transformations.


Gambir is a non-wood forest product with a potential of being used as wood adhesive, due to about 33% catechin in it. Meanwhile, catechins and sucrose have not been studied as adhesives. Therefore, basic characteristics of gambir-sucrose adhesives were investigated. In this research, adhesives were prepared by dissolving gambir and sucrose in distilled water, at different blending ratios of the gambir/sucrose such as 100/0, 75/25, 50/50, and 25/75 wt%. Furthermore, gas chromatography-mass spectrometry (GC-MS) was employed to determine the gambir chemical compositions, and Fourier transform-infrared (FTIR) spectroscopy was carried out to identify chemical bonds. Particleboards with a target density of 0.8 g/cm3 were then manufactured by hot-pressing for 10 min at 200℃. The internal bond (IB) strength of particleboard was subsequently measured. Based on the GC-MS analysis, 31.11% of catechin was identified. In addition, the viscosity, density, solid content, and gelation time of the adhesives, and insoluble matter content (IMC) in boiling water were 7.30~33.24 mPa.s, 1.2~1.3 g/cm3, 25.56~28.44%, 73~420 min, and 29.75~62.10%, respectively. Adding sucrose to the adhesive was observed to raise the IMC from 49.05 to 62.10%, at 180℃ and 200℃. FT-IR analysis showed that the gambir absorption peaks occurred at approximately 1620 cm-1, assigned to the C=O stretching of 5-hydroxymethylfurfural, which tended to increase with the addition of sucrose. The reaction between gambir and sucrose was observed in the form of the dimethylene ether bridge. The 25/75 wt% gambir-sucrose adhesives and 200℃ hot-pressed temperature resulted in the highest IB strength (0.89 MPa), and met the requirement of JIS A5908-2003 type 18. Consequently, the gambir-sucrose adhesive could be used as a particleboard adhesive.

With the continuous development and improvement of computer technology in practical application, the computer network security requirements are gradually improved, and the understanding of information security connotation is continuously extended. It has expanded from the original information security integrity and reliability to the integrity and non-repudiation of information. Information security began to prevent, detect and evaluate security theory and technology. The network can't make it exposed to many dangerous effects, suffering from various types of adverse factors of attack, how to strengthen the prevention of computer networks more security and reliability has become an important issue we are discussing, based on the importance of computer network security The development of common network attack mode and mechanism, and the development of effective security prevention and control strategies, encryption strategy, to enhance the long-term security services of computer networks have a positive and effective role in promoting. Theoretical Introduction of Network Security In essence, network security is information security on the network, which refers to the flow of network systems and data saved are not subject to accidental or malicious destruction, disclosure, alteration, the system for normal operation, the network service is not interrupted. Broadly speaking, all related to the network confidentiality, integrity, availability, authenticity and control technologies and theories related information are network security areas to be studied. The expanding range of computer communication is in far beyond the jurisdiction of the local area network. Therefore, the data in transit is vulnerable to attack. On the entire data communication networks, data protect measures must be taken to include the communication itself confirmed the legitimacy and ensure the legality of the communication data in two ways. A network running, its large amount of data and information are stored in the host or terminal, external memory, how to prevent unauthorized users access is essential. Core ARP attacks is to send fake ARP response to the target host, and the target host receives the response mapping between IP and MAC forged, and thus updates the target host cache. . In the actual computer network security management will often appear ARP attacks, such as IP address unauthorized use of the phenomenon, which not only affect the normal use of the computer network, but also due to address unauthorized use tend to have a higher authority, the enterprise unit caused a lot of economic losses and potential safety hazards, anti-ARP attack has become an important research field of computer network security. Physical security precautions are protected by computer systems, network servers, and other computer-related hardware facilities, mainly to prevent these hardware systems are subject to natural and man-made damage. In order to form a good physical security environment, the need to determine the user's identity, the use of authority, etc., to build an electromagnetic compatibility work environment, while the need to prevent the computer control room theft, destruction of the emergence of behavior. Common Computer Network Attacks Virus attacks for computer networks mainly refer to computer program instructions or code data that are artificially inserted into a process that can break down the computer's integrated functions and thus affect its normal use and can spread the virus by self-replicating.

Internet of things (IoT) is a trending technology now a days. Many things are getting shifted to IoT. IoT is related to our daily life actions and hence pose a risk to our privacy if not handled with care. Hence there is need to have secure IoT communication. This paper deals with the various proposed IoT security mechanisms which are capable of authentication, availability, encryption and integrity for secure communication. The paper has been focused on comparative study of emerging security mechanisms of IoT, their strengths and weakness, applications and open research issues. Each and every model has been compared and all the key features of the model have been presented. The IoT has a main requirement which is less power consumption, so the power consumption of various methods used in the proposed models has also been plotted.


A new technique has been developed to measure the carrier mobility and lifetime based on current transients produced by a sub‐picosecond laser pulse. The theoretical model we proposed agrees well with the experimental data. This technique has been applied to the material libraries fabricated by the combinatorial growth technique.


This essay is focused on knowing the activities carried out by the teacher to achieve body-aesthetic expression in students with difficulty in executing movements and overweight, in order to manifest the importance of body language in education through theory the educator Patricia Stokoe who was one of the first founders of body expression and dance, she defines it as, "the way to get around that bears the stamp of each individual" in which it is intended to help the body excited, through thought and transform the psycho activity movements and gestures stadiums posed by the pedagogue Henrri Wallon to reach the evolution of the movement and the importance it has given today the government in educational institutions through also known projects "learning on the move" which aims to run through the body movements promoting body language and aesthetics where children learn to develop their intellectual abilities of creativity and imagination of things. This generates interest, draws your attention and as a result invited to participate in the activities proposed integrating the working group, making express body and aesthetically.


The influence of gravitational light deflection by compact objects within a foreground on the apparent surface number density of distant sources around it is considered. In contrast to previous work (e.g., Canizares; Vietri and Ostriker; and Zuiderwijk), the effects of finite source extent, the galactic gravitational field at the location of the mini-lenses, and the simultaneous influence of several stars on the light beam are taken into account. The resulting number density enhancement depends sensitively on the source size and the shape of the intrinsic luminosity function of the sources. Although the number density of quasars around galaxies can be increased significantly, a large sample of galaxies has to be explored to isolate this effect from statistical noise. The applicability of these calculations to the recently discovered gravitational lens system 2237+0305 (reported by Huchra et al. in 1985) is discussed.


Josephson junctions with superconducting film electrodes on the surface of a semiconductor, whose surface region is doped with an impurity to a fixed depth up to degeneracy of free charge carriers, are investigated using a two-dimensional physical model based on a microscopic approach.


Security of cryptographic systems might be considered under many points of view. Traditionally, security of cryptology is seen on an abstract way: we make sure that the algorithms do not present any mathematical weaknesses which would make a cryptanalysis possible. However, for a few years, in an extended security model, physical attacks which use potential vulnerabilities of the material implementations are taken into consideration. One of the most threatening physical attack is presently the DPA attack (Differential Power Analysis), invented by Kocher in 1998 and presented in [1]. In this model, the assailant finds the secret keys used by the algorithms by analysing electric signals of the current consumed by the smart card. From this time, many countermeasures have been proposed in order to make those attacks difficult or just impossible. One of the most popular countermeasures consists currently in varying the internal clock frequency, in order to make DPA inappropriate. In this article, we propose a new way to launch an attack upon the smart card despite the desynchronisation of signals. This approach consists in analysing the curves of electric current by wavelets, and then to resynchronize them thanks to a minimization algorithm which will be presented in the following. The last step consists in selecting only well resynchronised curves, using statistical sorting algorithms, and then to perform a classical DPA attack on this selection. The result is better than the one we would obtain without doing those operations and will be explained and justified with many graphs in this article.


The IT industry has certain challenges fo r quality management. In order to meet business and organisational objectives and deliver quality softw are, it is essential to improve the organisational practices, and processes that produce the software. Software process improvement is both possible and essential. A key to successful software process improvement is makin g a step-by-step improvement effort, which graduall y evolves, into a paradigm shift in the way the organ isation does business. The processes and practices complement each other for improvement and both requ ire human effort from everyone in the organisation. Software project risk management is crucial for the software development projects. It is used for proj ect planning and control purposes during the project ex ecution. To success in managing a software project , project manager needs to understand the nature of s tware risks. The estimation of the software cos t remains one of the most challenging problems in sof tware engineering; as a preliminary estimate of cos t includes many elements of uncertainty. All project s have some uncertainties. Each project will have a different capacity for uncertainty. This paper dis cusses the issues involved in project uncertainty, and presents the feedback of Team leaders and team memb ers.


Special attention is paid to the problem of professional identity in general and journalism student professional identity in particular. The question of professional identity formation is important in the light of the existing changes in the journalism profession and information and communication technologies development. The aim of the research is to develop a draft of a program of extra curricular activities for journalism students aimed at their professional identity development. The research is based on general scholarly methods: analysis and modeling, studying and summarization of the research literature. The aim of the draft of the program of extra curricular activities for journalism students aimed at development of their professional identity is justified. The correlation of organizational and pedagogical conditions of professional identity formation is explained. The expediency of using the O4PO educational approach created on the basis of the CDIO approach is proved. Organizational and pedagogical conditions of professional identity formation as well as professional identity levels are explained. The authors conclude that it is necessary to develop professional identity of students not only in the educational process, but also in extra educational activities. Professional journalists can be involved in the educational process, which can be in general focused on the project techniques and practical activities. The program of extra curricula activity can be adopted by various higher education institutions, because the offered criteria and indicators of professional identity are universal.


The study was planed to assess the effects of the antihelmintic, Praziquantel, on haematologica l and biochemical indices in blood of Nile tilapia (Oreochromis niloticus). Fish were divided into 3 groups: first group received 40 mg Kg -1 body weight (bw) Praziquantel, and second group were given 60mg Kg -1 body weight (bw) praziquantel mixed into special prepared fish ration (private factory). Fish were examined every 48 hours after administration. Praziquantel treatment was characterized by scientificall y lower erythrocyte count, haemoglobin level, packed cell volume and total protein both dose levels after 48 and 96 hours compared to the third control group. The activity of alanine aminotransferase (ALT) was scientifically higher after 48 and 96 hours in treated groups, which could be attributed to slight hepatocyte damage caused by praziquantel. On the same manner the lyzozomal activity and phagocytic activity and antibody titer against Aeromonas hydrophila were lower than control values after 48 and 96 hours.


This paper presents photovoltaic system with a maximum power point tracking (MPPT) controller is connected to brushless dc motor drive for heating, ventilating and air conditioning fans. The MPPT controller is based on a genetic assisted, multi-layer perceptron neural network (GA-MLP-NN) structure and includes a DC–DC boost converter. Genetic assistance in the neural network is used to optimize the size of the hidden layer. Also, for training the network, a genetic assisted, Levenberg–Marquardt (GA-LM) algorithm is utilized. The off line GA-MLP-NN, trained by this hybrid algorithm, is utilized for online estimation of the volt-age and current values in the maximum power point. A brushless dc (BLDC) motor drive system that incorporates a motor controller with proportional integral (PI) speed control loop is successfully implemented to operate the fans. The digital signal processor (DSP) based unit provides rapid achievement of the MPPT and current control of the BLDC motor drive.


National, European, and international legislation regulates wildlife protection in Germany. Germany has comprehensively codified into national legislation numerous international and regional treaties. Furthermore, European Union regulations are directly binding in its Member States. Yet Germany's implementation of wildlife protection laws remains wanting. The gap between the country's comprehensive legal framework and related enforcement is glaring. Germany's decentralized administrative structure embedded in its federal system is the main impediment to better implementation of wildlife protection laws. While the country's federal structure might stand in the way of more centralized enforcement, a more coordinated approach still offers a realistic remedy to narrow the gap between Germany's legislation and enforcement. This article discusses Germany's wildlife protection laws, analyzes its enforcement approach, and recommends ways to improve.


In this work, we designed a series of superalkali‐doped Si12C12 nanocage M3O@Si12C12 (M = Li, Na, K) with donor–acceptor framework. Density functional theory calculations demonstrated that the HOMO–LUMO gap of the complexes conspicuously narrowed with increase of atomic number of the alkali metal, the value decreased from 5.452 eV of pure Si12C12 nanocage to 3.750, 2.984, and 2.634 eV of Li3O@Si12C12, Na3O@Si12C12, and K3O@Si12C12, respectively. This finding shows that the pristine Si12C12 cluster could be transformed to n‐type semiconductor by introduction of the superalkali M3O. We also showed that the superalkali doping remarkably enhanced the first hyperpolarizability of Si12C12. Among the studied systems, K3O@Si12C12 not only has the narrowest gap but also has the strongest nonlinear optical (NLO) properties, its first hyperpolarizability reached as high as 21695 a.u. The striking results presented in this work will be beneficial for potential applications of the Si12C12‐based nanostructure in the electronic nanodevices and high‐performance NLO materials. © 2017 Wiley Periodicals, Inc.


tion of the lung (CCAML) with concurrent severe fetal hydrops at 22 weeks' gestation. After detailed counselling was provided, the patient elected to undergo fetal surgery for prompt removal of the fetal pulmonary lesion. Rapid (6-8 h) fetal karyotypic analysis was required so that the patient could transfer to the surgical centre; a normal fetal karyotype was a prerequisite for fetal surgery. Patient B was found to be carrying a fetus with a large omphalocele (containing the bowel and liver) at 24.9 weeks' gestation, Rapid (6-8 h) fetal karyotypic analysis was necessitated by the patient's desire to terminate the pregnancy if a fetal chromosome abnormality was detected. In both cases, PUBS was performed to obtain fetal blood for karyotypic analysis; 3 cm3 fetal blood was obtained in both cases with no complications. Direct and culture analyses were initiated upon receipt of the specimens. Our method for rapid analysis of uncultured nucleated red blood cells has been previously described (Tipton et a/. , 1989; Tharapel et al., 1990). However, in these two cases, uncultured cells were harvested after only 2-3 h of incubation at 37°C followed by a short colcemid treatment. Two metaphases were available for cytogenetic analysis of both patients. Results from direct analyses were available 4 and 7 h, respectively, after obtaining fetal blood, and revealed 46,XX fetal complements in both cases (Figures 1 and 2). In both cases, direct analyses were later confirmed by analysis of cultured fetal lymphocytes. Prenatal diagnosis of CCAML was confirmed at the time of surgery for patient A; patient B subsequently elected pregnancy termination despite a normal fetal karyotype, with the prenatal diagnosis of a giant omphalocele confirmed at the time of prostaglandininduced pregnancy termination. Very rapid prenatal cytogenetic analysis using uncultured nucleated fetal red blood cells is possible in selected patients. However, the relatively poor quality of the metaphases obtained by this method apparently allows for only the detection of aneuploidy and gross chromosome defects. Such analysis does not provide optimal assessment of smaller structural chromosome abnormalities and therefore should be reserved only for situations in which rapid cytogenetic analysis of aneuploidies or large chromosome structural defects is essential for urgent obstetrical management.


Abstract The reaction of an allylic selenide with an excess of an O-alkyl-N-chloro-N-sodiocarbamate in methanol affords an alkoxycarbonyl-protected allylic primary amine with allylic transposition. The preparation of several tert-butoxycarbonyl- and benzyloxycarbonyl-protected amines is described.


This study explored nominalized expression types in an applied linguistics book and a biology book as 2 distinct disciplines. The books were carefully read, the nominalized expression types were identified, the frequencies of the nominalization types were counted, and eventually chi-square was administered. Results revealed no significant difference in using nominalization. Furthermore, the density of nominalization was calculated by dividing their frequency by the total number of words. Results acknowledged the greater concentration of nominalization in the applied linguistics book. Furthermore, the proportion of nominalization to grammatical metaphor was calculated. Results demonstrated the greater tendency towards nominalizing scientific information in the applied linguistics book. This research can contribute to a better understanding of nominalization in academic textbooks and, thus, improve English for Specific Purposes learners' use of nominalization in their writing. However, further research is needed to see how nominalization is exploited in other genres and other disciplines.


A new species of Dictyostelium, isolated from leaf mold collected in Poza Rica, Mexico, is described. The slime mold is characterized by the relatively small dimensions of its spores and myxamoebae, and more especially by its diminutive sorocarps-hence the name D. deminutivum. The slime mold may be cultivated satisfactorily in association with either Escherichia coli or Pseudomonas fluorescens upon agar media of very low nutrient content. Optimal growth and development occur in association with the latter bacterium upon 0.025% glucose-0.025% peptone agar when glass Petri plate lids are replaced with porous clay covers at the time cell aggregation begins. Aggregations that subsequently produce normal sorocarps typically appear mound-like and arise by the concerted influx of unaligned myxamoebae, either singly or in small groups, rather than by the formation and convergence of definite streams. Depending upon their size, such pseudoplasmodia may occasionally yield single fructifications, but as a rule they produce several sorocarps which arise near the periphery of the cell mass. In the completed sorocarp, the sorophore tapers gradually from base to apex and consists uniformly of a single tier of cells, the outlines of which may be difficult to discern, particularly in the terminal area.


Objective: To compare the ability of a smartphone-based app, the Smartphone Brain Scanner-2(SBS2), and pre-placed EEG cap (Easycap), costing ~300USD, to detect abnormalities with that of standard EEG. Background: There is a need for reliable, accessible and cost efficient EEG technologies in resource-limited settings. The SBS-2 is a portable, wearable device utilizing a 14 channel EasyCap administered by personnel easily after a few hours training. Data are transmitted via a wireless android tablet and read remotely by specialist neurophysiologists. Design/Methods: Children were enrolled at Ignace Deen Hospital, Conakry, in November 2017. Participants met the ILAE definition of epilepsy and sequentially had a standard 21 lead Xltek EEG and a 14 lead EasyCap EEG utilizing SBS-2 technology. EEGs were read remotely by specialist clinical neurophysiologists in the USA and Canada. Quality scores (0–10, 0 being totally uninterpretable, 10 perfect ) were also provided. Results: 97 patients (49 male, mean age 10 years) were enrolled. One standard (1.0%) and 11(11.3%) of SBS-2 EEGs were uninterpretable due to artefact. Mean quality scores were 7.37 and 6.76 for standard and SBS-2 EEG. Two patients had a standard EEG but not an SBS-2 EEG, yielding 83 pairs of studies for analysis. Mean recording time for standard and SBS-2 EEGs was 22.9 and 27.9 minutes respectively. Fifty-six(67.4%) standard EEGs and 31(37.3%) SBS-2 EEGs were abnormal. The sensitivity and specificity for any abnormality was 0.52 (CI 0.378,0.658) and 0.93 (CI 0.801,1.00). Epileptiform discharges were detected on 21 (25.3%) SBS-2 and 30 (36.1%) of standard EEGs. The SBS-2 had a sensitivity of 0.52 (CI 95% 0.324,0.708) and a specificity of 0.90(CI 95% 0.814,.944) for epileptiform discharges with positive and negative predictive values of 0.762 and 0.758. Conclusions: The SBS-2 application and EasyCap wearable device is easy to administer, moderately sensitive but highly specific for detection of EEG and epileptiform abnormalities in pediatric epilepsies.

Market research organizations put a lot of work into trying to reach consumers and make them cooperate with market surveys. Some subgroups are particular hard to reach, notably the young, the employed and the highly educated. Mobile market research is a promising way of catching these consumers since via mobile phones everyone can be accessed anywhere and at any time. This study investigates whether mobile phone surveys make it easier to interview the hard‐to‐reach consumers. Results reveal a significant effect of age on the likelihood of being difficult to reach, but different use patterns of the mobile phone or attitudes towards mobile phones do not affect the likelihood of being a hard‐to‐reach respondent.


The present work of degree pretends to give account of the impact that has a program based on mindfulness for the emotional regulation. The target population is adolescents because of their vulnerability, both because of the national context and because of the very characteristics of this stage of life. For this purpose, the implementation of a program based on mindfulness that has evidence on the improvement in emotional regulation (Metz et al., 2013), in an educational institution in the city of Medellin. Through pre-intervention evaluation and post-intervention evaluation, we aim to establish the impact and relevance of the mindfulness-based program in a sample of adolescents between 11 and 14 years old (n = 17) from a scale of emotional regulation in adolescents (REQ scale, Phillips & Power, 2007) and a mindfulness scale in adolescents (CHIME-A scale, Johnson, Burke, Brinkman, & Wade, 2016); Next to the post evaluation, an impact survey of the program is also applied. It is concluded that there is no significant impact on emotional regulation. The reasons for its ineffectiveness are discussed and the findings of the impact survey are presented, giving an account of a positive impact on the perception of adolescents about the program.


Book DetailsBacal, J. (Ed.). (2014). Mistakes I made at work: 25 influential women reflect on what they got out of getting it wrong. New York, NY: Plume, 304 pages, paperback, $16.00, ISBN: 978-0142180570.ReviewerSynopsis and EvaluationGathering insightful stories from 25 women in fields as varied as scientific research, writing, academia, politics, business, and music, Bacal explores a fresh approach to making it in the world of work-getting it wrong to get it right. So often, she notes, experts tell us that to grow, we must learn from our mistakes, but rarely are professionals willing to share those stories. Bacal and her collaborators do just that, exposing themselves and revealing errors that made them stop and consider the choices that led up to that moment, their place within their chosen field, their life goals. The pressure for girls and young women to '"have it together' often follows [them] to college and beyond" touching every aspect of their academic and professional careers and driving them into the role of "good girl," this damaging ideal prevents women from revealing their struggles and sharing lessons learned from mistakes for fear of seeming less than perfect (p. xi).The collection is divided into four sections: "Learning to Say No," "Learning to Ask," "Learning to Take Charge of your own Narrative," and "Learning Resilience." The stories in these sections seek to bond the reader with the writer; they are told in the first-person and in the author's own words. Reading these accounts is like listening to an experienced mentor or friend, learning from their wisdom, their joys, and their pains. More than anything, these are stories about sticking it out and finding the "power in talking about our mistakes and failures" (p. xv).In "Learning to Say No," novelist and professor of writing at the University of Michigan Sharon Pomerantz writes about being silenced in the first and worst job she ever had after graduating from college. "When you're from a blue-collar family," she explains, "you don't see the romance in blue-collar work. I had a college degree, and I wanted to use it, and I wanted my parents to see me use it" (p. 18). Pomerantz's mistake, she argues, was letting her voice be silenced and her health compromised by a demoralizing employer for fear of quitting and being deemed a failure. She learned from it and moved on.Leadership expert Selena Rezvani discusses mistakes she made in communicating with others and ignoring her own needs in "Learning to Ask." Rezvani recounts how realizing the degree she earned was not the right one for her helped her forge a new path, taking on new challenges to find ways to give voice to other women and inspiring them to become leaders. …


Phase coherent bond wavefunctions are shown to be approximate solutions of the antiferromagnetic Hamiltonian with the hopping term included (the t - J model) for t ≫ J. We determine the number of independent bond modes of this Hamiltonian in two dimensions. A brief discussion of the topological structure of the space of phases of the wavefunctions is given, and the main results of the analysis are briefly summarized at the end.


The processing technology and operating key points of loquat-milk were studied in this paper. The optimum proportion for fruit milk, fruit juice, sugar, organic sour, ethyl maltol, CMC-Na, pectin, the gum pectin and the tri-sodium citrate was 2.5%, 15%, 8%, 0.25%, 0.01‰, 0.30%, 0.10%, 0.05%, and 0.15% respectively. The final product has a taste of sweet and sour.


N the course of several summers' work among the Crow and the Village Indians of the upper Missouri, under the auspices of the American Museum of Natural History, a number of interesting problems have developed, some of which may prove of general interest. The first point to which I should like to call attention is the possible influence of the Caddoan tribes in the development of Northwestern Plains culture. Students of the Omaha have recently informed us that the earth-lodges, and probably also the Medicine Pipe ceremony, of that tribe owe their origin to the Arikara.1 It does not seem unreasonable to suppose that the earth-lodge of the Mandan and Hidatsa may have resulted from contact with the same member of the Caddoan family. As for the Medicine Pipe ceremony, the Crows, who share this performance with their kinsmen to the east, trace its introduction to the Hidatsa, while the latter positively assert that they themselves obtained it from the Arikara. In addition we have Maximilian's statement that the Hot dance of the Ruhptare Mandan and of the Hidatsa had been purchased of the Arikara.2 Here, to be sure, we must exercise some caution. The Hot dance described by the Prince comprised two spectacular features-a sort of fire-walk, and the plunging of the performers' arms into hot water. The latter has been described in connection with the Dakota heyoka organization;3 while the fire-dance was

Different state of polarization can be generated by different soil moisture,which relates closely to the wavelength,the roughness of the soil,the component of soil,and the incident zenith angle.According to Kodis' theory for scattering by a rough surface,a simple formula that relates the degree of polarization of soil to incident zenith angle,viewing angle and refractive index is obtained.Polarized reflectance data of different moisture red soil is collected with a polarimetric instrument and compared with the calculated results. Preliminary results of the change in degree of polarization for red soil with different moisture are presented. The results are significant for satellite agricultural remote sensing.


The melt grafting of maleic anhydride(MAH) onto(2-methyl methacrylate-1,3-butadiene-styrene)terpolymer(MBS resins) was used to prepare compatibilizer(MBS-g-MAH),and its effects on nylon 6(PA6)/MBS blends were studied by the scanning electron microscope(SEM),the melt flow rate(MFR)and mechanical testing methods.The results show that the anhydride group in MBS-g-MAH reacts with the amine end groups of the PA6,and MBS-PA6 copolymers are formed in situ,which effectively improves the compatibility between MBS and PA6.The size of MBS domains in the PA6 matrix is significantly reduced.The impact strength,tensile strength,flexural strength of PA6/MBS-g-MAH(70/30) blends increase 319%,54%,35%,respectively,over than PA6/MBS(70/30).MBS/PA6 alloys with excellent properties were obtained.

Abstract : This study analyzes the effect varying the number of permanent change of station (PCS) moves during a 20 year military career has on total family income. The number of PCS moves was varied from 5 to 9 over the 20 years to determine the effect on officer and enlisted family income for each of the services. This study limited the population to male military members married to civilian wives. Also, only PCS moves where the wife accompanies the member were considered. This study identified 4 items that can affect family income as a result of a PCS move. First, the family may have moving expenses that are not reimbursed by the government. Second, if the wife works, she must quit her job and suffer a period of unemployment. Third, the wife must seek employment at the new location. Usually, the new job will pay less than the old job due to foregone tenure. Keywords: Employment, Families (Human), Income, Women, Theses.


This paper researched the effect of stretching on electrical properties of LDPE/MgO. Pulsed electro-acoustic (PEA) method, dielectric analyzer and high resistance meter were used to research the DC breakdown, space charge behavior, permittivity, loss tangent and volume resistivity of neat LDPE and LDPE/MgO nanocomposites with concentration of 1, 3 and 5 wt% with and without elongation ratio of 1.1. Results indicate that the DC breakdown strengths of neat LDPE and nanocomposites decrease after stretching. The heterocharges near electrodes in neat LDPE change to homocharges after stretching and a large amount of positive and negative charges accumulated in samples with concentration of 3 wt% and 5 wt%. Meanwhile, homocharges near cathode electrode in nanocomposite with concentration of 1 wt% decrease a little and a small amount of positive charges were observed in the samples after stretching. Furthermore, there are different increases in amplitudes of permittivity in all samples after stretching as well as the loss tangents especially in the frequency domain from 10-1-102 Hz. The results of volume resistivity show that comparing with the nanocomposite with concentration of 1 wt% whose volume resistivity decrease after stretching, larger volume resistivity is observed in neat LDPE and nanocomposites with concentration of 3 wt% and 5 wt%. As we know, the electrical properties of polymer based nanocomposites is dominated by interface between nanoparticles and polymer matrix. After stretching, the area of interface may increase, which may increase the amount and depth of charge traps. Additionally, the free volume may increase and the force stressed on polar molecular may decrease, leading to the change of electrical properties of nanocomposites.


22123 Background: The workup of tumors presenting as metastatic disease is often laborious and expensive; many malignancies remaining unclassified as to site of origin. A gene expression test has been validated as an identifier of tissue of origin using metastatic tumors in which the primary site is known (Monzon 2007, Dumur 2008). Agreement with pathologist-issued diagnoses was 89.5% (95% CI 86.4 - 92.1%, n = 477). The test is not cleared by the FDA and was not validated in patients with CUP. We sought to determine the diagnostic performance of this test using CUP specimens from the Mayo Clinic tissue bank. Methods: Eleven fresh-frozen tumor biopsies derived from patients with CUP were processed with the Pathwork® Tissue of Origin (TOO) Test (Pathwork Diagnostics, Sunnyvale, CA). The TOO Test uses expression signals from 1,550 probe sets to quantitatively measure the similarity of tumor specimens to 15 tissues of origin. Each patient previously underwent a full clinical and imaging workup; tissue specime...


We use recent results of Intriligator and Wecht [1] to study the phase structure of = 1 super Yang-Mills theory with gauge group SU(Nc), a chiral superfield in the adjoint, and Nf chiral superfields in the fundamental representation of the gauge group. Our discussion sheds new light on [1] and supports the conjecture that the central charge a decreases under RG flows and is non-negative in unitary four dimensional conformal field theories.


While based at Adelaide Island, 30 November 1971—5 March 1972, Dr Charles Swithinbank and Dr Michael Walford installed a Scott Polar Research Institute Mk-IV radio-echo sounder in the British Antarctic Survey's DHC-6 Twin Otter aircraft. It was the Survey's third season of airborne sounding and the fourth of its aircraft to be used in this work. They flew a total of 61 hours on sounding runs over Graham Land, Palmer Land, and Alexander Island. Ice shelf profiles were generally flown at heights of 600 m above terrain, but many inland tracks were flown at a height of only 10 m. Low flying yielded bottom reflections in several areas where reflections had been unobtainable in previous seasons owing to heavy attenuation and also to surface scattering. Ice depths of up to 2 000 m were recorded on the Palmer Land plateau. Other tracks were specially flown in support of surface gravity and magnetometer surveys made in previous seasons.


Infectious bronchitis virus (IBV) is a contagious pathogen in fowl that results in economic loss in the poultry industry. In this study, the amino acids sequences of three structural proteins M, N, and S1 for five Iranian IBV isolated during 1998-2011 have been analyzed. Conserved and variable regions, hydrophobic characteristics and identity matrix were determined after alignment by Bioedit ver 126.96.36.199. The phylogenetic tree was obtained by using the neighbor-joining method within MEGA4. Similarity for M and S1 protein was lowest for IR-3654-VM and TW2575 / 98 isolate (0.862) and IR1061-PH and Georgia 1998 isolate / strain (0.41), respectively. For the N protein, highest similarity was found between Ur1 / 09 and Arkansas DPI (0.948). Four conserved regions for M and N proteins were recognized. In the S1 protein three hypervariable regions were detected in 52-90, 124-150 and 265-315 residues. In a phylogeny analysis all proteins were distributed in three clusters. Iranian IBV belonged to Mass cluster in phylogeny tree of M and N proteins. But S1 protein showed a close relationship with the California serotype and was distantly related to Mass serotype. The results showed that the Iranian IBV isolate was probably diverted from Mass strain that might be brought to Iran as a vaccine strain.


After observing severe symptoms of Sclerotinia sclerotiorum on the lower parts of potato plants (cultivar Agria), some sclerotia were observed and sampled. During sexual and asexual stages of this fungus, some morphologic characteristics of this pathogen were studied and its pathogenesis on cultivar Marfona was proved by a new method. This is the first report of Sclerotinia sclerotiorum on potato in Iran.


As their computational capabilities improve, attention has turned towards deploying deep learning models on edge devices to process the locally generated sensor signals. While these devices remain comparatively resource-constrained, early exit approaches have been shown to reduce the computational demands of on-device model personalisation training, which improves the accuracy and latency of a generalised model by fitting it to a specific use scenario. However, existing methods provide no mechanism to select the most informative signals for training. This work aims to improve prior approaches by interpreting the early exits as an ensemble of models trained with a joint loss function, retaining prior approaches' energy and latency savings while improving the accuracy. Additionally, it provides a principled mechanism to choose the signals that introduce higher uncertainty to the prediction due to the distributional shift and include them in the personalisation procedure, reducing energy consumption and latency. The key findings are a 42 % energy saving with exit-only retraining versus a standard (without intermediate exits) model, which increases up to 79 % when a subset of training samples was chosen according to the uncertainty estimation, alongside a 4.23pp increase in F1 score.


This study was performed to evaluate the long-term teachability of the stabilized hexavalent chromium contaminated soils treated with chromium reducing agent and soluble phosphate. The study shows that in the leachate was little detected and the remaining concentration kept below 0.1 mg/L due to the formation of geochemically stable hexavalent chromium phosphate minerals from the reactions of labile soil forms with the added soluble phosphate salt and chromium reducing agent. The results provide evidence for the potential use of the immobilization technique for the hexavalent chromium contaminated soil remediation in the near future.


The slow spontaneous development of cracks in the edges of injection moldings under "field" conditions has been observed for 30 years or more. While environmental stress cracking agents have long been implicated, the magnitude and distribution of the stresses associated with cracking have been obscure. The current study of these stresses involved polycarbonate as a model test material that was molded under systematically varied molding conditions. Surface tensile stresses, though rarely great enough alone to cause "dry" crazing or cracking were revealed through exposure to environmental stress crazing and cracking (ESC) agents. Using an old technique involving a set of calibrated ESC liquids, edge tensile stresses as great as 18 MPa were found in the edges of the moldings. Other, independent methods of stress assessment gave results in semiquantitative agreement with those of the ESC tests. Packing force, machine compliance, injection hold time, and mold flashing emerged as major variables either raising or mitigating stress levels. The root cause of the edge tensions is the mismatch in the times and pressures at which the skins and cores of moldings solidify. In short, skins quench at low pressure first, while cores solidify later during the packing stage. Upon release from the mold, elastic recovery of the core stretches the skin. More importantly, machine and mold compliances allow expansion of the part in the packing stage, during which certain areas of the skin are stretched. Solidifying the core during the packing preserves part of the skin extension as elastic strain. These effects are capable of outweighing the classical tendency of quenching to generate skin compression and core tension. A number of other effects, including release from the mold before the core has solidified, and flashing of the mold, have been found to limit the rise of skin tension.


In this paper we proposed a recovery and replacement algorithm mainly used to increase or strengthen the life of a sensor node when they complete the battery power. In generally wireless sensor network consists of lot of sensor nodes, hundred(s) or thousand(s) of nodes form a network to transfer the data from source node to sink node. The sensor node lose their battery power when it is used for long period of time, so it is difficult to recharge nodes of the sensor and also main in wireless sensor network is reduce the data loss, energy consumption and recovery and replace the effected nodes. So here we proposed a recovery and replacement algorithm which is a combination of genetic algorithm and grade diffusion algorithm. Here each node contains either two values those are binary values 0, 1. 1 means battery life greater than the threshold values otherwise it will be 0. This approach is better than existed algorithms, the number of faults decreases, reduces the data loss up to 98% and reduce energy consumption to 32%.


This study investigates the structural properties of super-heavy nuclei with Z = 130 by adopting the relativistic mean-field (RMF) theory within an axially deformed oscillator basis with the NL3 force parameter set. We study the binding energies, quadrupole deformation, nuclear radii, neutron separation energies, and other bulk properties. Moreover, we analyze the favorable decay modes for clear cognitive content of nuclei, such as alpha decay, using different formulae including the Viola-Seaberg, analytical formula of Royer, universal curve formula, and universal decay law. We compare these with the corresponding fission process. The spontaneous fission of super-heavy nuclei is studied with within the mass region . The results exhibit good agreement with finite range droplet model (FRDM) data. This formalism presents a significant step forward in the study of the structure and decay modes of the isotopes of Z = 130. With this appraisal, we investigate the possible shell/sub-shell closure for super-heavy nuclei adjacent by decay chains of alpha and other radioactive decay particles.


Objective To explore the effect of estrogen-like effects of soy isoflavones and its metabolite equol on DMBA induced breast cancer.Method The levels of serum estradiol and estriol were analyzed by Time-Resolved Immunofluorometric Assay(TRFIA).The expression of ERα、ERβ protein and gene in breast tissue were analyzed by Western-blot and RT-PCR.Results Compared with the model group,the breast cancer incidence in all doses of SI and equol groups decreased significantly.The level of serum estradiol in middle and high dose SI and equol groups was significantly higher than the model group while no difference in the serum estriol.The expression of ERβ protein and gene in all doses of SI and equol groups were significantly higher than the model group while only the low dose SI group was significantly lower than the model group for ERα protein and gene expression.Conclusion SI and equol reduced the incidence of breast cancer in ovariectomized rats,and changed the levels of serum estradiol and estriol,indicating that SI and equol had estrogenic effect,which may be mediated by ER.


The use of composite structures is increasingly present in the constructions of Civil Engineering. Steel-concrete composite beams, in particular, are structures consisting of two materials, a profile metal, located in predominantly region of tension, and a section of concrete, located predomi- nantly in compressed region, connected by metallic devices called shear connectors. The main functions of the connectors are: allow the joint work of slab-beam, restrict the longitudinal slipping and uplifting at the interface of the elements, and absorb shear forces. In this context, this work presents three-dimensional numerical models of composite steel-concrete beams, in order to simulate their structural behavior, with emphasis at the slab-beam interface. Simulations had been carried out by means of the ANSYS software, version 10.0, based on Finite Element Method. Results were compared with those provided by Standard Codes and with references found in the literature. Reported results demonstrate that the numerical approach is a valid tool to analyze the behavior of steel-concrete composite beams.

The presence of an archaeological site on Kosipe Sacre Coeur Mission was first noted in 1960, when axes and waisted blades were found by Father L. Willem during excavations for church foundations. Word of the site was sent to Mr W. Tomasetti, then Assistant District Officer, Department of Native Affairs, Tapini, and he informed White of it. Excavations were made there in June 1964 (White, 1965, 41–3; 1967). In 1966 the site was visited by Crook who collected further carbon and soil samples and in August 1967 White and Ruxton carried out further archaeological and geomorphological investigations. This report covers the entire history of excavations at the site. Kosipe lies about 135 kilometres north of Port Moresby and 20 kilometres north northwest of the Woitape Sub-District office, Central District, Papua, at 147° 16′ E, 8° 21′ S (fig. 1). The area around Kosipe has not yet been the object of a reconnaissance geological survey. Observations by Crook along the Woitape-Kosipe road, south of Kosipe and on the Kosipe-Tanipai track northwest of Kosipe along the Ivane River indicate that the oldest rocks are slates and other low grade metamorphics of unknown age with steeply dipping foliation. These are overlain, probably sub-horizontally, by several hundred feet of basic volcanics, probably largely basalt. The volcanics are probably of late Tertiary or early Quaternary age; they are strongly dissected and are not obviously related to any centres of extrusion.


Using a Taylor Series expansion for the magnetic field intensity measured at constant altitude provides an efficient way of continuing such fields onto any specified surface. This is particularly useful for draping of surveys flown at constant barometric altitude in areas of rugged topography. The Taylors Series approach also allows continuation to points below the level of the shallowest magnetic source present. Because derivatives of the observed field to increasing order are needed, low-pass filtering is needed to guarantee convergence of the series. Filtering parameters can be estimated from the power spectrum of the observed field and the maximum continuation distance required. We drape data from a constant altitude survey from British Columbia, Canada onto a surface with constant errain clearance. In comparison to an adjacent area flown in the draped mode, the resolution and amplitude of the major anomalies present are comparable, resulting in a more coherent combined data set than if no computational draping were done.


We present the Living Swift -XRT Point Source Catalogue (LSXPS) and real-time transient detector. Uniquely among X-ray catalogues, LSXPS is updated in near real-time, making this the first up-to-date record of the point sources detected by a sensitive X-ray telescope: the Swift -X-ray Telescope (XRT). The associated upper limit calculator likewise makes use of all available data allowing contemporary upper limits to be rapidly produced. The combination of these two products, along with the rapid timescale on which XRT data are available, enables us to carry out for the first time low-latency searches for new transient X-ray events fainter than those available to the current generation of wide-field imagers. In this paper we describe the system and the classification and dissemination of transient alerts it generates.


Specific heat $C$, thermal conductivity \ensuremath{\kappa}, dielectric permittivity \ensuremath{\epsilon}, electric polarization $P$, and Raman scattering experiments are performed on $\mathrm{C}{\mathrm{u}}_{3}\mathrm{Bi}{(\mathrm{Se}{\mathrm{O}}_{3})}_{2}{\mathrm{O}}_{2}X$ ($X=\mathrm{Br},\phantom{\rule{0.28em}{0ex}}\mathrm{Cl}$) single crystals. The Cl compound undergoes a structural phase transition at ${T}^{*}\ensuremath{\sim}115\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ evident in $C(T)$, $\ensuremath{\varepsilon}(T)$, and $\ensuremath{\kappa}(T)$ and accompanied by the appearance of unique phonon lines in Raman scattering. No evident structural changes are detected in the Br compound. At $Tl{T}^{*}$, a very weak polarization loop with a $P\ensuremath{\parallel}c$ axis is observed in the Cl compound. Both compounds order antiferromagnetically at comparable temperatures ${T}_{\mathrm{N}}\ensuremath{\sim}25\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ marked by sharp \ensuremath{\lambda}-type singularities. For $Tl{T}_{\mathrm{N}}$, an intensive mode of magnetic origin appears in both compounds. At the lowest temperatures, the energy of this mode is in good agreement with both the magnon excitation observed in infrared spectroscopy and the spin gap found recently in inelastic neutron scattering of the Cl compound.

Ecological consequences of prolonged mining natural management in the valley of the river Baksan are analyzed. Main sources of emissions of heavy metals compounds, the nature and extent of their pollution are revealed. Ecological indicators of the post-exploitation state of landscapes can be considered residual levels of toxic compounds in the grassrhizomatous systems of forage lands. Methods for reducing the concentration of chemical compounds in the main elements of valley-river landscapes are proposed. Indicators of the flow of Baksan affluents, on the basis of which it was concluded that "optimal amount of pollution" had reached the beginning of Zaiukovo village, are analytically calculated. Possibilities of embedding ecological blocks in the structure of old assimilated mining landscapes are considered. Biological recultivation is proposed to carry out in the form of simplified and less capitalintensive sanitary and hygienic works. The idea of the alternate use and recultivation of tailing dumps in the area of Bylym village is proposed to test.


For many years, C has been known as a fast, yet unfriendly language. Similarly, Java presents its own trade-offs, including more advanced language features at the cost of slower execution. As Java implementations continue to mature, this distinction has become less clear. Special hardware, better libraries and more sophisticated compilers have placed Java-based program execution times in the same realm as C-based programs. This paper demonstrates that superior performance is obtained by carefully selecting the appropriate language for implementing the system. In some cases, this will involve both languages interacting synergistically. For the SciMark 2.0 benchmark suite, using the Java Native Interface (JNI) increases performance by 2.29X for the best case and 1.29X on average compared to the C implementation on a Sharp Zaurus PDA. Simultaneously, the energy improvement for the best case is 2.26X and 1.24X on average.


The pronounced tendency of the political systems of "privatizing" and further on of capturing the hierarchization systems and those of social accrediting of values does not confirm the thesis of conversion towards a reflexive modernity (Ulrich Beck 51 1986), but it rather appears as the clearest symptom of the failure of the Western modernity. The moment when Beck requests a rational analysis of rationality and defines the world in which we live as a society of risks, he admits the failure of a thinking being in a deadlock. Failed modernity (reflexive or not) is directly confronted with a problem of trust (of ontological security) The leader without face is the armoured vehicle that the new political elite has hired out. The wightinstitution is the reaction (anti-democratical, but natural) of some systems devoid and exhausted of democratic errors. The most plausible argument by virtue of which this thinking is not totally outdated by the various tactics of institutionalization (it is not about genuine rationalization) wherein the modern world excels in, herein serves as a work hypothesis: the political body is the natural consequence of the spirit and inclinations of a homo religiosus. Modern society offers the wightinstitution as conjunctural substitute – an ersatz that is meant to soothe the collective lack of satisfaction towards the corruption of the pyramidal political body.


A dialysis method was applied to the determination of D-sorbitol in various commercial foods and toothpastes. Extraction was carried out by dialysis against methanol with cellulose tubing. An aliquot of the dialyzate was evaporated to dryness, and the trimethylsilyl derivative of D-sorbitol was formed. The TMS-sorbitol was injected into a gas-liquid chromatograph and measured by means of a flame ionization detector. The recovery of D-sorbitol was in the range of 89%•`109%, and the standard deviation was 6.9% (n=16).

Various devices are used in the gravitational concentration of minerals, including separators using water flow. In order to optimize parameters of devices, mathematical models of separation processes in enrichment devices are being developed. In this work, the mathematical model of a particle motion in the steeply inclined concentrator is developed. When modeling the collective movement of ore grains, the task of determining the probability of the position of a particle in the device appears depending on its parameters and operating modes. The developed mathematical model makes it possible to determine the probability of the position of the particle on the working surface of the device. The Gibbs ensemble method is used to solve the problem. To check the theoretical results obtained, experimental studies are carried out. Comparison of theoretical and experimental results show a fairly good agreement, which makes it possible to note the efficiency of using the Gibbs method in enrichment problems.


Making War and Minting Christians: Masculinity, Religion, and Colonialism in Early New England. By R.Todd Romero. (Amherst: University of Massachusetts Press. 2011. Pp. xvi, 255. $80.00 clothbound, ISBN 978-1558-49887-7; $26.95 paperback, ISBN 978-1-558-49888-4.) In 1629 the Massachusetts Bay Company chose as its seal the now-famous drawing of a New England Native standing in a barren wilderness clutching a bow and arrow and saying, "Come over and help us." Lesser known, perhaps, is an Indian peace medal from 1676 that similarly depicts a New England Native standing alone in a barren wilderness holding a bow and arrow, but the 1676 Native is speechless, has long hair, and two perfectly round breasts. It is precisely the meaning of this gendered transformation that R. Todd Romero wishes us to consider in Making War and Minting Christians. These images represent English perceptions of Indians as increasingly un-manly over the course of the seventeenth century, to be sure, but they also signal another change wrought by colonialism, warfare, and evangelization: the removal of the very things that allowed Indian men to live out either English or Indian masculine ideals in terms of subsistence, community leadership, and spiritual values. This book is largely structured around Native and Anglo-American understandings of masculinity, religion, and warfare between 1620 and 1676. Although Native and English societies "shared some cultural ground" on these issues, "they rarely recognized such commonalities, often focusing instead on differences" (p. 20). Drawing from a seemingly exhaustive and close reading of English print sources, a number of material objects, and a variety of Indian oral traditions, Romero argues that "Native and AngloAmerican conceptions of masculinity unfolded in counterpoint over the course of the seventeenth century and were central to the development of colonialism" (p. T). To make his case, Romero draws from an impressive number of episodes and exchanges that illustrate the various colonial and Native approaches to the issues at hand. Natives demonstrated masculinity through strenuous physical games like hubbub, particular modes of speechmaking, hunting, and warfare. For English colonists, manliness was demonstrated through patriarchy, particular kinds of labor (like farming), and warfare. Colonial officials sought to bend Native gender roles- particularly related to masculinity- to a thoroughly European ideal, even as they praised the few ways in which Indian masculine ideals already met English standards. Through colonial legislation and especially through the evangelization process and the resultant praying towns, John Eliot and other English missionaries and leaders tried to reshape Indian men and boys by curbing Indian games, encouraging them to grow gardens instead of fishing and hunting, cutting their hair short, attending church, observing the Sabbath, praying, accepting Christianity, wearing English clothes, providing spiritual leadership in their households, and fighting more like English men. …


30 Mev electrons were used to irradiate samples of p-type Ha C Te to study radiation induced changes in conductivity versus temperature. Samples were iheld below 959 K , ',c "' IO~~~~ 1 3 eetrn/while irradiated with doses between 4 x 10 electrons/ and 6 x iO15 electrons/ . Little or no change in conductivity was detected for the lower dose levels. Conductivity steadily decreased with increasing dose level, showing a 50% decline at 100K for the maximum dose. The decrease in conductivity was smaller at higher temperatures. Approximately two hour post-irradiation temperature excursions up to 300fK, resulted in a 25% restoration of the conductivity at 100fK. The mobility of the samples, irradiated at the maximum dose level showed a 3 to 6 fold increase, while the majority carrier concentration decreased by a factor of 7 to 10 times the pre-irradiation values. All samples irradiated with dose levels above 1 x d 5 electrons/cm , converted from p to n-type at 295?K, but remained p-type at 77 K. It was hypothesized that radiation induced donor defect levels in the conduction band were responsible for the reported changes


A new technique to improve feature extraction task is proposed. The main benefit of using scaling process is to avoid attributes in greater numeric ranges dominating those in smaller numeric ranges. Moreover, the adoption of this developed technique achieves best accuracy with low computational complexity for object recognition. Note that, through experiment, the method has been proven to be accurate at 63.75%. We concluded that the recognition of image is hard and complicated not only because of the handwriting ambiguity but also due to the similarity between characters and their positions in a word. This paper has presented a simple scheme for binary template selection in a context of feature extraction based on entropy. It is experimentally shown that the proposed algorithm can be employed to select an effective template. In addition, this method uses low computational processes, which provide hierarchical sparse method (HSM) to increase recognition rate within fewer computations and short time.


The present paper focuses on a resolution-based automated reasoning theory in a lattice-valued logic system with truth-values defined in a lattice-valued algebraic structure - lattice implication algebras (LIA) in order to handle automated deduction under an uncertain environment. Particularly, as a continuation and extension of the established work on binary resolution at a certain truth-value level α (called α-resolution), a non-clausal multi-ary α-generalized resolution principle and deduction are introduced in this paper for a lattice-valued first-order logic LF(X) based on LIA, which is essentially non-clausal generalized resolution avoiding the reduction to normal clausal form. Non-clausal multi-ary α-generalized resolution deduction in LF(X) is then proved to be sound and complete. The present work is expected to provide a theoretical foundation of more efficient resolution based automated reasoning in lattice-valued logic.


Outlier detection has attracted more and more attentions from researchers due to its extensive applications in various fields. In this paper, a new SVM (Support Vector Machine) model is presented for a special type of outlier detection problem, where the majority of training data is normal sample and it also contains a small number of anomaly samples. The experimental results on several datasets show that the proposed algorithm is valid and can achieve better accuracy compared with the published algorithms.

A new kind material Cr5 steel used for backup roll was studied in this paper.Its CCT curve,quenching and tempering temperature were determined by test.The steel mechanical properties were also measured.The results show that the steel has superior hardenability,resistance to softening on tempering and good comprehensive properties.


This paper constitutes an analysis and summary of some of the test data obtained to date in conjunction with the forced-cooling of a full scale, 1.5 mile long, 138 kV, pipe-type cable line. Two methods of forced-cooling are discussed: (1) the return pipe method and (2) mechanical refrigeration. The paper is largely concerned with the return pipe method since the mechanical refrigeration tests are still under way. Design equations for estimating pressure drop and oil temperatures are presented.


A near-field source localization method is proposed for 2-D direction-of-arrival (DOA) and range estimation based on a symmetrical cross array. It first employs the conjugate symmetry property of signal autocorrelation for different time delays to construct a conjugate augmented spatial–temporal cross-correlation matrix, then the extended steering vector is decoupled to avoid the usual multidimensional search based on the properties of the Khatri–Rao product, and finally three 1-D MUSIC-type searches are employed to obtain the results. The proposed method can realize automatic pairing of multiple parameters associated with each source and it also works in the underdetermined case. Furthermore, the stochastic Cramer–Rao lower bound with different time delays is derived. Compared with two existing methods, simulation results demonstrate that the proposed method provides satisfactory estimation performance for both the DOA and range parameters at low signal-to-noise ratio and with a small number of snapshots.


BackgroundClinicians use serum immunoglobulin E (IgE) and/or skin prick test (SPT) to help decide whether a child is suitable for a food challenge. Performing a food challenge (FC) or supervised feed (SF) is the gold standard for a definitive diagnosis of type 1 food allergy. Food challenges are labour intensive and our unit currently has long waiting lists for food challenges, exacerbated by the COVID 19 pandemic. This study aims to determine if the current thresholds for home introduction can be altered.ObjectivesTo evaluate the reaction rate, and the severity of reactions, of tuna and almond challenges performed in our hospital.To use results collected to examine whether the thresholds for home introduction of both tuna and almond should be reviewed.MethodsRetrospective data analysis of tuna and almond challenges performed in the Paediatric Allergy Service at St George's Hospital. Electronic medical records were reviewed of all patients who underwent an oral food challenge between April 2018 to October 2020 at St George's Hospital. Clinical history, results of SPT and specific IgE to tuna and almond and the outcome of the challenge were extracted from the hospital database.ResultsTuna14 children underwent a tuna food challenge. None were observed to have a positive result. One child had an inconclusive challenge as the final sample was refused;prior to this the child did not experience any signs of an allergy reaction. All these children had a known allergy to other fish.Almond77 children underwent an almond only challenge;8% (6) of these were supervised feeds, the other 92% (71) were food challenges. 8% (6) children were observed to have a positive almond challenge. One child had an inconclusive challenge as the final sample was refused;prior to this the child did not experience any signs of an allergy reaction.50% (3) of children with a positive challenge were managed with cetirizine alone, at the correct dosage for age. The other 3 children complained of mild symptoms which resolved with no treatment.ConclusionsNo children had a positive tuna challenge and the thresholds for home introduction of tune could be reviewed and relaxed.96% of children who had an SPT less than 2mm tolerated the almond challenge. For those that reacted, all reactions observed were mild to moderate. The threshold for home introduction of almond could also be reviewed and relaxed.
