According to the status quo of low permeability reservoir fracturing,combining fracturing with reservoir engineering,through numerical simulation the matching of the irregular artifical fractures and the row-like well network have been analyzed.The results show that for 10 years seeing from the exploitation of the single well daily production,cumulative production,the output of wells or injection wells with irregular fractures which are neither completely open in both sides of the well is better than completely open in one side.Meanwhile the number of wells,is not completely open the greater which are not completely open,the greater the impact on output.


In a recent paper, Green & Parke (1974) drew attention to some of the systematic problems posed by benthic members of the Haptophyceae. Particular attention was given to Ruttnera spectabilis Geitler (1942) the type species of its genus, which was shown by the fine structure of the zoids to be a member of the Haptophyceae with a characteristic rudimentary haptonema and not, as had been thought previously, a member of the Chrysophyceae (sensu Christensen, 1962). Attention was also drawn to the close similarities between R. spectabilis and Chrysotila lamellosa Anand (1937) both in the vegetative and motile phases, but no formal taxonomic changes were made pending the completion of the comparative reinvestigation of both these species together with C. stipitata Anand, the type species of the genus Chrysotila (so designated by Bourrelly, 1957).


The invention relates to a loosening moisture regain machine capable of improving the stability of the leaf moisture content and a control method. The control method comprises the following steps that firstly, the water addition is kept unchanged, different steam flows are set through a steam regulating valve, the moisture of leaves discharged from a material discharging port is detected through a moisture detector, and a numerical value of the moisture of the leaves is recorded; secondly, the steam addition is kept unchanged, different water additions are set through a water regulating valve, the moisture of leaves discharged from the material discharging port is detected through the moisture detector, and a numerical value of the moisture of the leaves is recorded; thirdly, a relation of equivalence between influences of steam on the moisture of the leaves and influences of water on the moisture of the leaves is obtained. According to the control method for improving the stability of the leaf moisture content, a total water addition ratio is set, so that the moisture of the tobacco leaves is more even and more stable after the leaves are loosened and the moisture is regained and the technical quality of products is effectively guaranteed.


The first stage of the process (the excitation of autoionized 3P(-) states by electrons) and its second stage (the resonance ionization of the helium atom) are considered on a unified basis within the framework of Fano' s theory using the diagonalization method for the description of the properties of autoionized states. A qualitative comparison of the results obtained with the existing experimental data is made.


Patients who undergo lower extremity amputation secondary to the complications of diabetes or peripheral artery disease have poor long‐term survival.

Milling process is the process of cutting the workpiece using a cutting tool
with many cutting tooth rotating pivot either clockwise or anti clockwise. Cutting
or slicing the workpiece can occur if the movement of the chisel cuts imposed on
the workpiece that has gripped there will be friction / collision that will result in
cuts in the workpiece, this can happen because the constituent material hardness
over the chisel has a hardness of the workpiece. In machining surface roughness
quality is very important because surface roughness is defining factor to know good
or not product resulting form machining process.
In this study used a endmill tool with carbide material and titanium alloy
Ti6Al4V as workpieces using CNC milling. Cutting process parameters such as
cutting speed (Vc), feed rate (fz), depth of cut radial (ar), and depth of cut axial (aa),
to know the optimization of surface roughness values with artificial neural network
method. Artificial neural networks (ANN) is a computational method that mimics a
biological neural network system in the human brain.
Based on the results testing of surface roughness affects the variation of
cutting conditions. Ti6Al4V surface roughness maximum value obtained was 1.76
μm in the can on testing to 20. When the value of Vc = 100 m / min, fz = 0.158
mm/tooth, ar = 0.32 mm, and 7.07 mm aa = 10 mm , Meanwhile, the minimum value
obtained Ti6Al4V surface roughness was 0.22 μm is on testing 10. With test cutting
conditions, Vc = 125 m / min, feed rate (fz) = 0.04 mm / tooth, Depth of cut radial
(ar) = 0 , 25 mm, Depth of cut axial (aa) = 10 mm. It can be concluded that the bigest
value of the cutting speed generated the bigest value of Ra. Similarly, the feed rate,
the bigest of feed rate valued generated the bigest of surface roughness Ra value so
the rough surface is generated.
Then the test result data were analyzed using ANN method back propagation
with using neura network architecture 4-1-1, 4-2-1, 4-3-1, 4-4-1, 4-5-1, 4-6-1, 4-7-
1, and 4-8-1 model. To knowing what neural network architecture have the best
prediction by looking at the architecture which has the smallest error rate and the
correlation surface roughness values between the surface roughness predictive
values based analyzed ANN and the surface roughness values from test. Analysis
was done by using MATLAB software, be obtained neural network ANN 4-7-1 is the best neural network with MSE (mean square error) value 0,02. Prediction value
Ra analysis ANN optimum is 0,29 μm, on the testing with cutting speed condition (Vc= 125 m/min) and feed rate (fz = 0,04 mm/tooth).

President Obama's Educate to Innovate initia- tive has provided billions in additional federal funding for science, technology, engineering, and mathematics (STEM) education programs across the country. The Administra- tion's recognition of the importance of STEM education— for global competitiveness as well as for national secu- rity—is good and important. But the past 50 years suggest that federal initiatives are unlikely to solve the funda- mental problem of American underperformance in STEM education. Heritage Foundation education and national security analysts explain that, though Educate to Innovate is intended to raise the U.S. "from the middle to the top of the pack in science and math," the federal program's one- size-fits-all approach fails to remedy the underlying prob- lems of academic performance and does not plug the leaky pipeline in the American education system.


A Wireless Sensor Network consists of small, self-configurable sensor nodes, which have very small storage capacity and low processing power. Sensor nodes are scattered over a field and they organize themselves in specific manner automatically to interchange information they sense. The organization of nodes plays a vital role from the point of view of efficiency of network. In this paper, a comparative assessment of WSN topologies is given, which leads the judgment of efficiency of sensor networks.


Mount Etna, largest and most active volcano in Europe, is located on the east coast of Sicily. Continuous GPS and InSAR monitoring show the highest displacement rates at the coast reaching up to ~3 cm per year. Information on the dynamics and mechanisms of the submerged offshore domain is completely unknown. In 2016, an acoustic geodetic network of five autonomous seafloor transponders was deployed across a dextral fault north of Catania Canyon. This fault is interpreted as the offshore extension of the Tremestieri Fault System and as the offshore southern margin of the sliding sector of the unstable flank. The seafloor geodetic transponders measure acoustic distances across the fault, absolute pressure and tilt for a period of up to 3 years. In July 2017, we downloaded 14 months of data via an acoustic link. The data show clear evidence for sliding of the volcanic flank towards the Ionian Sea and revealed the first observation of active displacement of an underwater landslide by acoustic geodesy.


Herein, we introduce an inorganic comprehensive experiment called the synthesis and characterization of the zinc coordination polymer. The undergraduate students would know the research frontier of metal organic frameworks (MOFs) and improve the comprehensive scientific research and innovation ability during the processes of the synthesis of the organic linker, MOFs and corresponding structure-property relationship. The experiment is based on the inorganic, organic and analytical chemistry knowledge and experimental skills, which can be used as a comprehensive open experiment for senior students.


In this study we take up challenges regarding researcher positionality, representation, and the construction of difference as a launching point to reflexively analyze our own practices within a research project exploring multilingualism, multiliteracies, and teacher development. Our data were drawn from a teacher study group we facilitated during the first phase of a two-year study. We draw on poststructuralist understandings of discourse, power, and performativity and use elements ofCritical Discourse Analysis (CDA) to conduct a close thematic reading of two moments of discomfort in one study group meeting, and we critique our own complicity in the discursive production of difference. Further, we engage tools of process drama to theorize how we might have structured and responded to interactions differently during one of these same moments in order to address these challenges more successfully. We conclude by arguing for approaches and interpretive tools for researchers that could help to reimagine as well as respond both ethically and analytically to issues of representation in language and literacy research.

Freezing of sea water in the ballast tank must be prevented in the merchant vessels which navigate the Arctic Ocean in winter. Therefore, heating coils need to be arranged to heat the tank. For this purpose, it is necessary to comprehend the freezing phenomena, natural convection, and temperature distribution in the ballast tank. The authors have established a tank heating analysis method which is applicable to the design of a rational heating coil arrangement. This paper describes the analysis method and the comparison of model test data with analytical results, and also shows an example of application of the method to an actual vessel.

A technique has been developed for the reactive high‐vacuum codeposition of niobium nitride at rates in excess of several hundred A/sec. With gaseous ammonia as the nitrogen source, films with transition temperatures in excess of 13°K have been fabricated. The depression of the transition temperature from values reported for sputtered films is attributed to ammonia decomposition chemistry. In addition, 4.2°K critical currents in excess of 106 A/cm2 have been measured for 1‐μ‐thick films.


This article discusses the specifics of the impact of digitalization on the state of teenagers social deviations in modern society. The characteristic features of adolescent behavior are analyzed taking into account the agespecific features of the course of socialization of this age cohort. The necessity of sharing a personalsituational approach when considering the social deviations of teenagers in the context of digitalization, as well as the principles of consistency and determinism, were identified and justified. Based on the study, the author suggests that in a positive way, the digital resource is very mobile and dynamic, has an instrumental function for teenagers, and it is the basis for the search for like-minded people, social contacts and information. The authors emphasize that digitalization makes it possible to create a new layer of social reality, one where conditions for destructive forms of social behavior appear, with more freedom than in real life. Summarizing the study, the authors outline ways to positively overcome the current situation.

Abstract. Accurate particle classification plays a vital role in aerosol studies. Differential mobility analyzer (DMA), centrifugal particle mass analyzer (CPMA) and aerodynamic aerosol classifier (AAC) are commonly used to select particles with a specific size or mass. However, multiple charging effect cannot be entirely avoided either using individual technique or using tandem system such as DMA-CPMA, especially when selecting soot particles with fractal structures. In this study, we demonstrate the transfer functions of DMA-CPMA and DMA-AAC systems, as well as the potential multiple charging effect. Our results show that the ability to remove multiply charged particles mainly depends on particles morphology and instruments setups of DMA-CPMA system. Using measurements from soot experiments and literature data, a general trend in the appearance of multiple charging effect with decreasing size when selecting aspherical particles was observed. Otherwise, our results indicated that the ability of DMA-AAC to resolve particles with multiple charges is mainly related to the resolutions of classifiers. In most cases, DMA-AAC can eliminate multiple charging effect regardless of the particle morphology, while particles with multiple charges can be selected when decreasing resolutions of DMA and AAC. We propose that the multiple charging effect should be reconsidered when using DMA-CPMA or DMA-AAC system in estimating size and mass resolved optical properties in the field and lab experiments.


The 933 km2 Benguê catchment in northeastern Brazil is characterized by distinct rainy and dry seasons. Precipitation is stored in variously sized reservoirs, which is essential for the local population. In this study, we used TerraSAR-X SM (HH) data for an one-year monitoring of seasonal changes in the reservoir areas from July 2011 to July 2012. The monitoring was based on acquisitions in the ascending pass direction, complemented by occasional descending-pass images. To detect water surface areas, a histogram analysis followed by a global threshold classification was performed, and the results were validated using in situ GPS data. Distinguishing between small reservoirs and similar looking dark areas was difficult. Therefore, we tested several approaches for identifying misclassified areas. An analysis of the surface area dynamics of the reservoirs indicated high spatial and temporal heterogeneities and a large decrease in the total water surface area of the reservoirs in the catchment by approximately 30% within one year.


Abstract Dimcarb, a liquid distillable 1 .8 :1-dimethylamine-carbondioxide complex which can be used as a preparatively profitable dimethylamine source, displays unusual properties in view of a salt ("dimethylammonium dimethylcarbamate"). The dynamic structure behaviour has been investigated by1'H, 13C, and 15N NMR spectroscopy: At ambient temperature dimcarb underlies a rapid dimethylamine change between ammonium and carbamate functionality (⊿G ≠ about 58 kJ/mol). On further temperature decreasing prototropic interactions between dimethylammonium and dimethylamine as well as dimethylcarbamate and dimethylcarbamic acid species are additionally revealed. Timely averaged, ionic structures predominate, obviously dimethylammonium dimethylcarbamate combinations as intimate ion pairs. Involved dimethylcarbamic acid can be trapped as methylester in high yield by reaction of dimcarb with diazomethane. Moreover, the dimethylcarbamic acid trimethylsilylester, obtained from dimcarb with the aid of trimethyl-chlorosilane, affords a crystalline product by methanolysis at -78 °C. probably dimethylcarbamic acid, which decomposes above -50 °C under carbondioxide elimination and regeneration of dimcarb.


Background: Identification of healthy people at high risk for severe COVID-19 is a global health priority. We investigated whether blood biomarkers measured by high-throughput metabolomics could be predictive of severe pneumonia and COVID-19 hospitalisation years after the blood sampling. Methods: Nuclear magnetic resonance metabolomics was used to quantify a comprehensive biomarker profile in 105,146 plasma samples collected in the UK Biobank during 2007-2010 (age range 39-70). The biomarkers were tested for association with severe pneumonia (2507 cases, defined as diagnosis in hospital or death record occurring during a median of 8.1-year follow-up) and with severe COVID-19 (195 cases, defined as diagnosis in hospital between mid-March to mid-June 2020). A multi-biomarker score was derived for prediction of severe pneumonia based on half of the study population and validated in the other half. We explored how this biomarker score relates to the risk of severe COVID-19. Findings: The biomarker associations with risk of severe COVID-19 followed an overall pattern similar to associations with risk of severe pneumonia (correlation 0.83). The multi-biomarker score, comprised of 25 blood biomarkers including inflammatory proteins, fatty acids, amino acids and advanced lipid measures, was strongly associated with risk of severe pneumonia (odds ratio 1.67 per standard deviation [95% confidence interval 1.59-1.76]; 3.8-fold risk increase for individuals in upper vs lower quintile). The multi-biomarker score was also associated with risk of severe COVID-19 (odds ratio 1.33 [1.17-1.53]; 2.5-fold risk for upper vs lower quintile) and remained significant when adjusting for body mass index, smoking, and existing respiratory and cardiometabolic diseases. Mimicking the decade lag from blood sampling to COVID-19, severe pneumonia events occurring after 7-11 years associated with the multi-biomarker score to a similar magnitude (odds ratio 1.43 [1.29-1.59]; 2.6-fold risk for upper vs lower quintile) as for severe COVID-19. However, the short-term risk of severe pneumonia events associated to the multi-biomarker score at even 3 times higher magnitude (odds ratio 2.21 [1.95-2.50]; 8.0-fold risk for upper vs lower quintile in analysis of the first 2 years after blood sampling). Interpretation: In decade-old blood samples from the UK Biobank, a biomarker score measured by high-throughput metabolomics is indicative of the risk for severe COVID-19. The molecular signature of biomarker changes reflective of risk for severe COVID-19 is similar to that for severe pneumonia, in particular when accounting for the time lag to the COVID-19 pandemic. The even stronger association of the biomarker score with 2-year risk for severe pneumonia lends support to promising screening possibilities for identifying people at high risk for severe COVID-19.


Simple Summary Osmylopsychopidae, an extinct family of Neuroptera, is closely related to the extant Psychopsidae. The sporadic records of this family and limited preservation of fossil specimens have hindered the understanding of the evolution of Osmylopsychopidae. In this paper, one new genus with four new species of Osmylopsychopidae are described from the Middle Jurassic Jiulongshan Formation of northeastern China. These newly discovered osmylopsychopids with a forewing length of ca. 10 mm (implying small body size), clearly distinguished from the traditional sense of Osmylopsychopidae, suggest that Osmylopsychopidae possibly underwent a significant diversification during the Mesozoic. Abstract One new genus with four new species sharing the similar character of a forewing length of ca. 10 mm, namely, Minipsychops spasulus gen. et sp. nov., Minipsychops polychotomus sp. nov., Minipsychops densus sp. nov., and Minipsychops unicus sp. nov., are described from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia in China. These new insects can be attributed to Osmylopsychopidae for their distinctive configuration of costal space and the venations of RP1 and Cu. Compared with the typically medium to large body sizes of known osmylopsychopids, these new Middle Jurassic taxa of a particularly miniaturized lineage not only enrich the species diversity of Osmylopsychopidae, but also enhance our understanding of the historical evolution of these poorly known lacewings.


The dominant model of schooling is a technical-rational management model based on behavioral, positivistic, quasi-scientific language, which has shifted attention from the art and craft of teaching to the "science and technology" of teaching. However, this model and the language which it uses limit educational thinking. Emphasis on value-neutrality in the farm of observation has led to domination of the field of education by an "if-then" mentality, a reduction of the cause-effect model borrowed from natural science. An alternative mode, based on Eisner's notion of educational connoisseurship and educational criticism, provides educational evaluation that is qualitative in nature, with the critic in education following the example of critics in literature, theater, film, music, and other visual arts. The mode of discourse used in this alternative paradigm is non-discursive and metaphorical, and the critic draws upon his knowledge/conceptual/experimental base to describe, interpret, and evaluate what he experiences. The interplay of the descriptive, interpretive, and evaluative aspects proyide multiple perspectives that serve to expand the dialogue of educators to alternative possibilities, and to help educators appreciate the complexities of the educational process.

This study reports five cases with rheumatoid arthritis requiring salvage surgery after posterior atlantoaxial fusion. Patients were divided into two groups, the first group included two nonunion and one malunion of atlantoaxial fusion and the second group included two who develope subaxial subluxation. In the first group, one case of nonunion could be again treated by atlantoaxial fusion after removing the primary grafted bone and reduction of subluxation. But the other nonunion case, and the patient with malunion needed occipitocervical fusion to be performed because their subluxation could not be reduced. After surgery, occipitocervical pain disappeared in all cases of the first group, but myelopathy persisted in the two cases treated with occipitocervical fusion. In the second group, MRI revealed severe compression of the spinal cord at subaxial level in both cases. They were treated with anterior decompression and fusion followed by posterior decompression and fusionRegardless of the spinal cord decompression shown on MRI one case with a long history of myelopathy prior to sur-

To evaluate the performance characteristics of CA 19-9 radioimmunoassay and the clinical significance of serum CA 19-9 assay in patients with malignancy, serum CA 19-9 levels were measured by radioimmunoassay using monoclonal antibody in 135 normal controls, 81 patients with various untreated malignancy, 9 patients of postoperative colon cancer without recurrence and 20 patients with benign gastrointestinal diseases, who visited Seoul National University Hospital from June, 1984 to March, 1985. The results were as follows; 1) The CA 19-9 radioimmunoassay was simple to perform and can be completed in one work day. And the between-assay reproducibility and the assay recovery were both excellent. 2) The mean serum CA 19-9 level in 135 normal controls was . Normal upper limit of serum CA 19-9 was defined as 21.0 U/mL. 4 out of 135(3.0%) normal controls showed elevated CA 19-9 levels above the normal upper limit. 3) One out of 20(5.0%) patients with benign gastrointestinal diseases showed elevated serum CA 19-9 level above the normal upper limit. 4) In 81 patients with various' untreated malignancy, 41 patients(50.6%) showed elevated serum CA 19-9 levels. 66.7% of 18 patients with colorectal cancer, 100% of 2 patients with pancreatic cancer, 100% of 3 patients with common bile duct cancer, 47.1% of 17 patients with stomach cancer, 28.6% of 28 patients with hepatoma and 60.0% of 5 other gastrointestinal tract cancers showed elevated serum CA 19-9 levels. 5) The sensitivities of serum CA 19-9 related to resectability in colorectal and stomach cancer were 33.3% in resectable colorectal cancer, 83.3% in unresectable colorectal cancer, 41.7% in resectable stomach cancer, 60.0% in unresectable stomach cancer respectively. 6) The sensitivity of serum CA 19-9 in 9 patients of postoperative colorectal cancer without recurrence were 33.3% and significantly decreased compared with that of untreated colorectal cancer, 66.7% (p


Background C-reactive protein (CRP), a blood inflammatory biomarker, is associated with the development of Alzheimer disease. In animal models of Parkinson disease (PD), systemic inflammatory stimuli can promote neuroinflammation and accelerate dopaminergic neurodegeneration. However, the association between long-term systemic inflammations and neurodegeneration has not been assessed in PD patients. Objective To investigate the longitudinal effects of baseline CRP concentrations on motor prognosis in PD. Design, Setting, and Participants Retrospective analysis of 375 patients (mean age, 69.3 years; mean PD duration, 6.6 years). Plasma concentrations of high-sensitivity CRP were measured in the absence of infections, and the Unified Parkinson's Disease Rating Scale Part III (UPDRS-III) scores were measured at five follow-up intervals (Days 1–90, 91–270, 271–450, 451–630, and 631–900). Main Outcome Measure Change of UPDRS-III scores from baseline to each of the five follow-up periods. Results Change in UPDRS-III scores was significantly greater in PD patients with CRP concentrations ≥0.7 mg/L than in those with CRP concentrations <0.7 mg/L, as determined by a generalized estimation equation model (P = 0.021) for the entire follow-up period and by a generalized regression model (P = 0.030) for the last follow-up interval (Days 631–900). The regression coefficients of baseline CRP for the two periods were 1.41 (95% confidence interval [CI] 0.21–2.61) and 2.62 (95% CI 0.25–4.98), respectively, after adjusting for sex, age, baseline UPDRS-III score, dementia, and incremental L-dopa equivalent dose. Conclusion Baseline plasma CRP levels were associated with motor deterioration and predicted motor prognosis in patients with PD. These associations were independent of sex, age, PD severity, dementia, and anti-Parkinsonian agents, suggesting that subclinical systemic inflammations could accelerate neurodegeneration in PD.


4G/5G EPC over Network Functions Virtualization (NFV) complemented with Software Defined Networking (SDN) framework is envisioned to be a novel paradigm of network architecture that supports a variety of access technologies and solves growth challenges and requirements such seamless mobility management. Network-based localized mobility management scheme such as Proxy Mobile IPv6 (PMIPv6) is designed to address many of the drawbacks such as additional signaling and over-the-air tunnel overhead associated with global mobility protocols like Mobile IPv6 (MIPv6). In some deployment scenarios, PMIPv6 results in high registration, end-to-end delivery, inter- and intra-domain handoff (roaming), and route optimization latencies due to this unnecessary signaling and detour traffic path. To address these problems, in this paper we propose a route optimized PMIPv6 virtualized function over SDN framework. We first describe how PMIPv6 mechanism is transformed into a suit of virtualized network functions, and proposes design and implementation for SDN-based EPC networks in detail. Finally, simulation results show that proposed framework can improve the performance in terms of the registration, end-to-end delivery, inter- and intra-domain handoff (roaming), and route optimization latencies compared to original non-SDN based PMIPv6 framework.


Q&A with Author Brock Craft Brock Craft How did you get started with Arduino? I got started using Arduino because I wanted to be able to keep track of the temperature inside the house compared to the temperature outside. That way, I could see how the seasons and outside temperature fluctuations affect our energy use - and, of course, our energy bill! I needed a way to take readings of temperature sensors and send those to my computer. There are a lot of ways to do this, but at the time, I could see that Arduino would allow me to do so many more things. I got my hands on one as fast as possible and in the process met the Arduino team. Why do you think Arduino has become so popular so quickly? The main reason is that it is easy to use. It used to be pretty difficult for the average person to program and upload code to microcontrollers - and they were a lot more expensive! So even if you got the code working, if you then hooked it up wrong and fried it, you were out a lot of money. Arduino has some built in protection against this, and it is much easier to make connections to the microcontroller because of the way the board is laid out. Any advice for someone who might be interested in Arduino, but isn't sure where to start? Well, first of all I'd check out the Arduino website to get a good idea of what Arduino is all about and what it can do. Then, I'd grab a copy of Arduino For Dummies, by my friend John Nussey and try out some of the simple demos in the book. Once you've got that under your belt, you can take a crack at some of the projects in my book too. What are some of the interesting things you can create with Arduino? There are all kinds of cool things you can do, and I've tried to include a wide range of projects in my book that demonstrate many of its capabilities. Since you can use an Arduino to read just about any kind of sensor data, the obvious thing to do is use it to detect changes in the environment, light temperature, light levels, and soil moisture. You can even detect sound levels and do motion detection, as well. You can also use it to control things like LEDs, motors, and just about anything you can turn on or off with a switch. The fun part is mixing these together - you can do mashups of sensors and things they control, like linking a pet door to Twitter. What is your all-time favorite Arduino project that you've either worked on or heard about from someone else? My favorite right now is called the "Immaterials Project" by Timo Arnall and his colleagues. It uses an Arduino to control a 12-foot pole that has a string of LEDs mounted on it. The Arduino lights up the LEDs sequentially, based upon the strength of nearby Wi-Fi network signals. They carry around the stick in city streets and photograph it with long-exposure photography. The effect is that you see a sort of bar chart laid over the street scene, showing how strong the network signal is. I like it because it reveals the invisible signals that we are walking around in all the time, but never really think about. What is a good project for new Arduino users to start out with? The usual project for beginners is called "Blink", which shows you how to flash an LED. Computer programming languages all have what's called a "Hello World" program where you get the code to do the most basic thing - display something on the computer screen. Since an Arduino doesn't have a screen, the equivalent is controlling an LED. Just about anyone can get started flashing an LED in a few minutes and then learn how to change how it flashes. From there, you just build up your knowledge and skills as the basic principles pretty much stay the same. What should people expect when they open a copy of Arduino Projects For Dummies? They will find a bunch of different projects that are about using the Arduino for doing clever things. There are easy projects you can build in a couple of hours and harder ones that might need a weekend or more to finish. And all of them can be extended to do more cool stuff that I didn't think of! I've explained how to build them in a straightforward way so that everything you need to know is in there, including what materials you need for the projects and where to get them. I've also tried to include lots of photos of building the projects - which you don't always get in other books or online. I hope anyone who gets the book will be inspired to make something even cooler than what is already covered in the book! Bonus Content - Click Images to Enlarge Each project in the book has an easy-to-follow layout diagram detailing how to hook everything up. A pictures and a scrolling text marquee is one of the easiest projects for new users to build. Here's a close up of the GPS tracker and data logger project from the book. The best part about the remote-controlled car project, aside from the Pringles can wheels, is that you can control the car with any remote control you might have lying around the house. You can build an LED cube that you can animate and even create your own patterns for fun. The book includes a programming tool that can be downloaded online, which makes it super easy to design your own animations.


Abstract This paper investigates false recognition of semantically related distractor items. Using the Deese (1959) false memory paradigm, we investigated the predictions that MINERVA2 (Hintzman, 1988) makes for true (exemplar) and false (prototype) recognition. In MINERVA2, exemplar recognition is primarily due to a high degree of similarity to a single memory trace and prototype recognition is due to the summing of smaller amounts of similarity across many memory traces. MINERVA2 predicts that: (1) while performance for exemplars and prototypes increases at approximately the same rate at low levels of learning, additional learning produces a greater increase in performance for exemplars than for prototypes; (2) reducing the number of exemplars studied will decrease performance more for prototypes than for exemplars; and (3) decreasing associative strength of an exemplar to a prototype should increase exemplar performance while decreasing prototype performance. The results of four experiments support the predictions of the model and are consistent with the notion that true recognition is primarily due to a high degree of match to a single trace, while false recognition is due to the summing of smaller amounts of similarity to numerous traces.


A radar signal fusion method based on DT-CWT and TVAR is presented for the non - stationary character of radar scatter data in the paper. Radar signal is decomposed with dual-tree complex wavelet transform. In different wavelet subspaces, Signal is modeled and predicted with TVAR model. New radar signal can be obtained through the complex wavelet reconstruction. Finally, a super-resolution one dimension range image can be achieved by amplitude-phase compensation and fusion two radar signals.

Although its roots are seen in ancient times and despite the fact that it role in the historical developments of Turkish and world music, the darbuka and its performance have not been extensively taken under musicological studies. This article is about the performance analysis of the darbuka techniques developed by studied under the light of the fact that the existing musical discourse has been transferred from teacher to student through ages orally. Parallel to the cultural changes, the advancement of civilizations throughout the course of history, differences. Therefore the material of the clay darbuka has been the most important factor affecting the different techniques of playing the instrument. The reason why we emphasize on the performance analysis is that it is of fundamental importance to make observations and decipher its characteristics within the discipline of musical theory.


AlGaN=GaN high electron mobility transistors (HEMTs) are excellent candidates for high power and high frequency applications at elevated temperatures owing to their superior material properties [1–4]. To date, most of the efforts on GaN-based electronic devices have been directed towards depletion mode (D-mode) AlGaN=GaN HEMTs. However, some applications involving low-power digital circuits require the integration of both E-mode and D-mode HEMTs. Therefore, there is a great interest in the realisation of E-mode AlGaN=GaN HEMTs. Owing to the large polarisation charge in the AlGaN=GaN heterostructure, fabrication of GaN-based E-mode devices is more difficult compared to other material systems such as InP and GaAs. There have been only a few reports on these devices, and to date, the device performance is as yet unsatisfactory [5–7]. In this Letter, we report the fabrication of 1.0 mm gate-length E-mode AlGaN=GaN HEMTs grown by metal organic chemical vapour deposition (MOCVD) on SiC having a peak extrinsic transconductance of 248 mS=mm. These devices exhibited a current density of 470 mA=mm, a threshold voltage of 75 mV, an fT of 8 GHz and an fmax of 26 GHz. These results are significant improvements over previously reported GaN-based E-mode HEMTs.


The purpose of this study is to know condition of company finance that is what will be growth condition, price of share and profitability company.

This study examined the influence of narrative and propositional reasoning in a classroom context. Students viewed 1 of 4 videotaped instructional simulations that varied the controversial issue presented by the teacher and ways of reasoning about it. After viewing a videotape, students rated the expertness, trustworthiness, and attractiveness of the teacher, and the effectiveness of instruction. They rated the teacher as more attractive and the presentation more effective when he used a narrative rather than a propositional approach.


Strong brands are defined by their ability to deliver their brand promise. In order to do so, brand management must orchestrate the organisation to ensure consistency in the vision of the organisation and its stakeholders. This study aims to identify the relationship between brand management and brand promise delivery. Two separate quantitative studies were performed to map the level of brand management of organisations and their brand promise delivery. Study 1 revealed that organisations could be categorized into sceptics, beginners, advanced and experts level of brand management. Sceptics have the least developed brand management and expert have aligned the brand throughout the entire organisation. Study 2 revealed the extent to which each organisation was delivering their brand promise. Combining the results of both studies revealed that of the various levels of brand management, beginners have the lowest brand promise delivery and experts are the best in delivering their brand promise. The study also revealed the influence of brand management as whole is greater than implementing separate constructs as certain facets on their own have a negative influence on external brand promise delivery. It is therefore recommended that organisations focus on each aspect of brand management and not solely focus on one or two facets in order to improve brand promise delivery.


There exists a myriad of studies on technology acceptance theories that have been used to study the adoption of Internet banking services world over. However, Technology acceptance model (TAM) has gained wide popularity compared to other behavioral theories. This study uses some constructs from TAM and IDT to investigate the factors that influence IBA in Botswana's Gaborone city working class and college students. A quantitative research study approach, using a questionnaire as the research instrument was adopted. The study notes that among other factors, PEOU, PU and trust have a significant influence on IBA. The study also notes that IB awareness and resources must be increased for them to contribute significantly to the positive adoption rates of IB in Botswana. Lastly, instead of taking a confirmatory approach to behavioral studies like this one, the authors would like to suggest that an exploratory study maybe more appropriate with structural equation modeling as the preferred analysis technique. This can reveal more insights into the data. However, if this is to be done, the sample size needs to be increased. Sample size is one of the weakness of this study hence we cannot generalize the findings to the whole of Botswana. DOI: 10.5901/mjss.2014.v5n20p596


The two most commonly used definitions of strictly positive real (SPR) transfer functions are reviewed. Contrary to what has been previously suggested, it is shown that the least restrictive (weak) definition of the two is clearly related to the Yacubovich-Kalman lemma. A relationship between time and frequency domain conditions pertaining to the weak definition of SPR systems is established. An alternative proof is given to show that a PR plant is stabilized by any (weak) SPR system connected in negative feedback.<<ETX>>


WARNING: Exposure to benzene and carbon tetrachloride, solvents used in the dental office and in the home, can and does cause death. Xylene and methylchloroform are less hazardous but possess similar solvent properties. Dentists are advised to follow tenets of safety when choosing an organic solvent.


In this paper I want to propose a closer and somewhat different view on what is usually called "human-machine-interface". To introduce this new view, I make a distinction between cognitive and physical interfaces. I will show that we need to think about interfaces not just in terms of materiality, but also in terms of cognition. Furthermore the aim of the article is to show, how philosophy of technology can contribute to the developmental process and to enhance the design of interfaces.


We explain the current situation of the relationship between the Kashiwara-Vergne Lie algebra $\mathfrak{krv}$ and the double shuffle Lie algebra $\mathfrak{dmr}$. We also show the validity of Ecalle's senary relation for small depths.


We show in this paper that measurements of charge-state distributions for 5--1600 eV Li, Na, and K scattered from a clean Cu(001) surface provide an excellent probe of the dynamics of atom-surface charge transfer. The neutralization probabilities, measured as a function of the perpendicular velocities of the scattered atoms, are qualitatively different for the three species. These differences reflect the high sensitivity of the charge transfer in this energy range to the energies and lifetimes of the atomic resonances near the surface. The measured neutralization probabilities are found to depend on the parallel velocity component of the scattered atom, even though the velocities at which these experiments are conducted are relatively low. The data are compared to several models of the charge-transfer process. Agreement with the data is achieved using a model based on the one-electron Newns-Anderson Hamiltonian and using calculated values for the alkali-metal resonance parameters.


Headspace liquid-phase microextraction with room temperature ionic liquid material, 1-butyl-3-methylimidazolium hexafluorophosphate ([C4MIM][PF6]) as extractant for the determination of organochlorine pesticides including 2,4 '-DDT and 4,4'-DDT from water were investigated in this study. The factors such as salt content, sample pH, operation temperature, stirring rate, extraction time, microdrop volume, and sample volume were found to have significant influence on this process. Results show that the satisfactory extraction conditions were as follows: 30% NaCl (w/v), 800 rpm, 30 min, 60 °C, and 10μL ionic liquid.

ABSTRACT Continuous fauna surveys have been conducted by the Frog and Tadpole Study Group of New South Wales Inc. (FATS) at Wallingat since 1994. Between 1983 and 1994 occasional surveys were carried out by the founding members of FATS. Unlike the early surveys, which were entirely opportunistic, FATS established a series of regular survey locations within Wallingat State Forest (SF) and these sites have been routinely surveyed twice a year since 1994. In addition, opportunistic surveys were also undertaken for other fauna. The data collected from these surveys were dutifully reported to the state government agencies, who recorded the wildlife data (now under the auspices of the Office of Environment and Heritage NSW). The fauna records supplied by FATS (and other natural history groups) documented a rich and diverse fauna in Wallingat SF that includes 26 frog species (including 1 threatened species), 40 reptile species (including 2 threatened species), 30 mammal species (including 6 threatened species) a...


On the basis of the poetry Michael Ondaatje published before Secular Love (1984), few readers would claim that it has much in common with confessional writing. If anything most of his earlier work stands opposed to the school=s constitutive assumptions, and even when his lyrics are personal, they are rarely intimate. The speaker in most of them seems to be Ondaatje but he=s rarely interested in dealing directly with his most personal and most problematic emotions and situations: the voice is too laconic, the tone too detached and the attitude to the self is ironic, even selfmocking. Yet we often sense that the artifice and control not only shape and present the material at hand but simultaneously hint at repressed or displaced experiences and aspects of the self with which the writer is unwilling or unable to deal. Ondaatje=s suicidal herons and artists, his fascination with the jungle, the various hints at autobiography in The Collected Works of Billy the Kid (1969), >Letters & Other Worlds= and Coming through Slaughter (1976) B three studies in pathological creativity B all point obliquely or symbolically to the pressure of personal events on the work. Without resorting to a confessional aesthetic, Coming through Slaughter, his novel about a jazz cornetist whose obsessive art leads to silence and madness, and the crucial lyrics >Letters & Other Worlds,= >Burning Hills,= and >White Dwarfs= certainly reveal a compulsive fascination with an intensely subjective and directly expressive art. But in these works a confessional approach is not part of what Helen Vendler, referring to other poets, calls >the structural and symbolic aesthetic strategies to which [he] has been driven in coping ... [with] some personal donnee which the poet could not avoid treating= (xii). The local donnee in Secular Love is a love affair and the breakup of a marriage. And the >aesthetic strategies= show Ondaatje


A novel regime of high frequency radiation generation via reflection at the electron density spikes in under- dense plasma is proposed. Intense driver laser pulse propagating in underdense plasma forms dense electron singularities near the front part of the bow waves, moving at relativistic velocity. By irradiating a source pulse counterpropagating to the electron density singularities, it is reflected and compressed, producing ultrashort coherent high order harmonics with frequency upshift.

This paper proposes a new method for achieving minimal hardware multiple intermediate signature analysis whereby n signatures are checked against a single reference. With a single reference, checking multiple signatures requires the same amount of hardware as for checking only one. However, checking multiple signatures has many advantages. In comparison to the method described by Y. Wie and A Ivahou (1993) in [13], the proposed method is faster by a factor of 2/sup k/, where k is the signature size. E.g., to check two 16-bit signatures against a single reference, the total CPU time cost (Sun Sparcstation 2) is less than 4 sec. for a test length of up to 2/sup 20/, independently of the size of the circuit under test (CUT).<<ETX>>


We investigate symmetry-preserving gapped boundary of (2+1)D topological phases with global symmetry, which can be either bosonic or fermionic. We develop a general algebraic description for gapped boundary condition for symmetry-enriched or fermionic topological phases, extending the framework of Lagrangian algebra anyon for bosonic phases without symmetry. We then focus on application to the case with U(1) symmetry. We derive new obstructions to symmetry-preserving gapped boundary for U(1) f -symmetric (2+1)D fermionic topological phases, which are beyond chiral central charge c ´ and electric Hall conductivity σ H . These obstructions are given by a simple Gauss-Milgram type formula valid for super-modular category, and regarded as a higher version of c ´ and σ H .


This paper presents a new method, successfully developed by the Motor Industry Research Association (MIRA) and Ford Motor Company UK, to simulate the impact response of adhesively bonded structures. It discusses: (1) existing simulation methods; (2) adhesive material properties; (3) adhesive bondline methodology; (4) interface elements; (5) adhesive bondline connection to a structure; (6) adhesive material model; (7) beam section properties; and (8) the preliminary mathematical results, which successfully predict the experimental results. The method has been applied to simulate a box beam impact with and without adhesive bonding. The results predict the higher energy absorption of a weld-bonded beam compared with a spot-welded beam, and the locations where the adhesive fractured during tests. The new method is compatible with existing automotive industry crashworthiness simulation methods, and can be easy to use with existing finite-element models. It is also being applied to joint-test specimens, structural components, and full vehicle models, to assess the performance of adhesive bonds and further develop the adhesive bonding methodology. This work will raise confidence in structural adhesive bonding for future application, and help to develop low-weight vehicles requiring adhesives in energy-absorbing areas. For the covering abstract see ITRD E107095.


Many distribution system operations (e.g., state estimation, control, fault detection/localization) rely on the assumption that the underlying topology is accurately defined. In general, topology identification is a challenging problem in distribution systems as these systems are unobservable with a very limited number of available measurements. In this paper, we tackle this problem by designing a compressive sensing framework that jointly estimates the systems states and network topology via an integrated mixed integer nonlinear program (MINLP) formulation. Two reformulations of the original MINLP problems are investigated. Firstly, in order to remove the nonlinearity in the MINLP formulation, a mixed integer linear programming (MILP) problem that employs auxiliary variables is derived. Furthermore, to achieve a faster solution, convex relaxation of the original formulation is derived. Finally, using a Markovian model for topology changes, prior information about system topology is used to improve topology identification particularly when a limited amount of measurements is available. Simulation results on IEEE 37-bus test feeder and IEEE 123-bus test feeder illustrate the efficiency and scalability of the proposed approaches from both state estimation and topology identification point of view (even with 30% of available data).


Recently, a new underground pumping station was constructed 41.5 m below sea level and equipped, which has now become the main underground pumping station of the Velenje Coal Mine (VCM). In this study, use of terrestrial laser scanning (TLS) to acquire the 3D data of the engine room of the underground pumping station is presented. TLS is an advanced technique in spatial information data acquisition, which allows the equipment in the underground pumping station to be digitally captured with unprecedented resolution and accuracy. Integration with metric imagery allows 3D photorealistic models to be created for interpretation and visualisation. The final result shows the actual 3D image of the object recorded with a relative accuracy of a few millimetres. TLS is ideal for capturing the original state before construction commences and the final state after its completion, as well as for both observation of surface changes and detection of deformations. When we have an accurate 3D model of each component in the engine room of the underground pumping station, any maintenance, future upgrades, or modifications can be made with reference to the original state.

Abstract : With the high risk and cost in fielding High Energy Laser (HEL) weapon systems, the development process must include computer simulation models of weapon system performance from the engineering level up to predicting the military worth of employing specific systems in a combat scenario. This research effort focuses on defining how to measure lethality for HEL weapons in an Advanced Tactical Laser (ATL) scenario. In order to create an effective measure for direct comparison between the emerging laser weapon system and existing conventionally delivered weapons, lase time in seconds is presented as a measure comparable to rounds required to cause the desired effect at the target. An examination of input parameters which influence the output power of the laser at the target and thus the required lase time is presented with particular attention being paid to atmospheric conditions and vulnerable bucket size. Results include output tables providing the lase time required for meltthrough of a set of generic truck-type vehicular ground target aimpoints.


Presented is a critical analysis of E. FROMM's The Anatomy of Human Destructiveness (London, 1974), with respect to his contradictory approach to the question of the biological foundation of psychology and his abuse of quotations of and references to Marx. In FROMM's own critical analysis of K. Lorenz, S. Freud, and B. F. Skinner, he presents persuasive arguments based on impressive data from different modern sciences, against the instinctive and mechanistic theories of human nature. But when establishing his own position, he draws the same biologically based conclusions as his opponents, although he expresses them in different terms. Furthermore, in attempting to make Marx an ally of his own views, he succeeds only in misquoting or misconstruing Marx: he quotes Marx only in order to compliment him or when the quote is neutral with respect to his own ideas, or when actually citing Marx in support of his own views, he gives his own, rather imprecise interpretation of Marx.


A method is described in which a pulsed laser is used to probe the sea. Backscattered light is analyzed in time, intensity and wavelength. Tyndall, Raman and Brillouin scattering are used to obtain the backscatter turbidity, sound velocity, salinity, and the temperature as a function of depth.


Biodiesel plays an important role in reducing the dependency of petroleum fuels and reduce environmental pollution.

The flow around a two-dimensional isolated airfoil is visualized in a smoke wind tunnel. The test airfoil consists of the leading and trailing parts, which is fixed on the test section wall. The leading one can be rotated not more than 9 degrees around the point of 1/4 chord length. The flow visualization was carried out under the following conditions; Reynolds Number Re=1.01×104-2.82×10 5, attack angle α=0-20 degrees. The visualized result shows that the shape changing can control the flow field around the airfoil near the stall angle of the original shape.


D. Roosevelt, whom he resembled in many ways, had a sense of history, which transformed him from a rough and tumble, if resourceful, politician to a statesman. He mastered the lessons of politics as he matured in responsible leadership. He responded instinctively to the growing demands for expertness in government in an age of specialization. His political life is stirring proof of the creative working of the democratic process in the big city. SIDNEY I. POMERANTZ

Future bent-pipe FDM satellite systems [1,2,3,4] ask for a high flexibility concerning bandwidth-to-user assignment, which is achieved by merging several elementary channels (granules) to one wideband channel, as required by the users. For instance, a respective scenario is described in [5,6,7], where the requirements are most challenging for the forward uplink: the overall capacity of 40GHz is realised by 10 gateway beams of 2x2GHz using dual polarisation in the uplink. After separation and down-conversion of the two polarisation components to a suitably low intermediate frequency, each 2GHz signal is split into two signals of a bandwidth of about 1GHz applying analogue filtering in order to alleviate the A-to-D interface (ADI) requirements. High speed ADI digitise these 1GHz signals at a sampling frequency of fi=2.4GHz.


Penetrating head injury remains an important issue even in modern neurosurgery. Less frequent than other neurosurgical diseases, they may still pose some management problems. The authors present one extremely rare case of suicide attempt by penetrating head injury with harpoon at a male middle aged patient associated with iatrogenous pneumothorax. Operated with a simple occipital craniectomy, the patient had a pretty good recovery with minimal neurological deficit (facial paresis).


Magnetic field measurement is an important analysis method in mining industry. Magnetic distortion of inertial navigation system (INS) is one severe error of portable geomagnetic field vector measurement instrument. A correlation algorithm is proposed for component compensation, in which magnetometer attitude information is provided by INS, and the geomagnetic field vector without magnetic anomaly is measured. Experiment result shows that distortion field vector of INS can reach hundreds of nT, which are suppressed to about 4.8 % after compensation, thus it is effective for component compensation. The magnetic anomaly measurement using magnetic intensity test (TMI) method and the proposed instrument are analyzed. In application, the proposed compensation way shows effectiveness comparing with several traditional compensation methods. In addition, the potential applications in mining industry are discussed.

Dr Richard Barker, Director General of the Association of the British Pharmaceutical Industry, spoke to Future Medicinal Chemistry about the key issues affecting the industry and the approaches for overcoming them.


Introduction: Covid-19 is an infectious respiratory disease, caused by SARS-CoV-2. This disease appeared in China and, subsequently, there are cases on all continents, being declared a pandemic by the World Health Organization (WHO). Objective: to describe the implementation of the new coping protocols in Covid-19 in a Basic Health Unit (UBS) in Federal District. Methods: this is a cross-sectional study of the monitoring actions of users with suspected flu syndromes based on the Coronavirus Clinical Management Protocol (Covid-19) in Primary Health Care (PHC). A survey was carried out from March 19, 2020 to May 11, 2020. Results: 194 projects were carried out with users related to Covid-19 in GSAP. Mostly males (52%). The most attended age group was children from 0 to 10 years old (24.7%). A more prevalent comorbidity was the Systemic Arterial Hypertension (SAH) on those users who had some other chronic disease. Telephone contact was not possible in 48.5% of the participants. Conclusion: The implementation of the Impact Protocol in a Positive Way in the Monitoring of Users with Flu Syndrome who will seek care at the UBS. The need to create other strategies to contact users besides telephone contact was identified.


Changes in land use and management practices to store and sequester carbon are becoming integral to global efforts to address climate change, yet knowledge and evidence gaps abound. This paper analyses the most pressing deficiencies in understanding carbon storage in both soils and above ground biomass, focusing on the semi-arid and dry sub-humid systems of sub-Saharan Africa inhabited by many of the world's poor. We identify important interdisciplinary opportunities and challenges for researchers, policy makers and practitioners to work together in order for the poor to benefit from carbon storage in dryland systems, through both climate finance streams and collateral ecosystem service benefits delivered by carbon-friendly land management. We propose new integrated monitoring approaches that offer considerable scope for developing the new knowledge, methods and tools required for enabling pro-poor, climateand ecosystem service-smart development. Collaborative multi-stakeholder working across scales from the local to the regional is stressed in outlining routes to ensure that scientific advances can inform policy and practice to deliver carbon, ecosystem service and poverty alleviation benefits.


Terrestrial radar interferometers (TRI) are complimentary to spaceborne synthetic aperture radar systems for deformation monitoring in natural terrain: they permit shorter revisit times and greater flexibility in acquisition mode and timing. The additional diversity offered by polarimetric data can also be beneficial for TRI observations because polarized waves are sensitive to the dielectric and geometrical properties of the scatterers. Polarimetric data helps to distinguish different scattering mechanisms in a resolution cell while at the same time estimating terrain displacements. However, the polarimetric scattering signatures of natural surfaces at Ku-Band are not as well characterized as the ones at longer wavelengths, owing to relative rarity of full polarimetric systems operating in Ku-band. This band is often employed in TRI to obtain a fine azimuth resolution with a limited aperture size. This article aims at assessing the potential of polarimetric measurements in Ku-band TRI through an experimental study of polarimetric scattering signatures of natural surfaces using two datasets acquired over a glacier and in an agricultural and urban scene. The main finding of this analysis is that the Cloude–Pottier entropy is high for all land cover types; it is only observed to be less than 0.5 for scatterers with a large radar cross section. Several plausible hypotheses for this observation are formulated and tested, the most likely assumes a combination of depolarizing scattering from natural surfaces and the effect of the large ratio of wavelength to resolution cell size.


The present study aimed to elaborate on the characterization of Felix Salinger, the main character in Morris Gleitzman's Holocaust novel entitled Once. Through textual analysis, the study revealed that the novel portrays Felix Salinger as an eight-year-old Jewish boy who was religious, brave, caring, and creative. Felix Salinger's religious character involved strong tolerance toward Christianity and high respect for the higher powers in their various names. His bravery was shown when he had to accomplish many challenging tasks at the risk of his own life. Felix Salinger's caring characterizations were supported by his observant, attentive, and selfless characters. His creativity relied on his imagination to create solutions to various challenges he faced, including creating stories to entertain others as part of his survival. These findings imply that children can be very resilient in challenging situations.


Objective
To investigate the value of CT in detecting incidental extracardiac findings (IEFs) when used for attenuation correction during SPECT/CT myocardial perfusion imaging (MPI).

Methods
A total of 520 patients (288 males, 232 females, average age 65.8 years) who underwent SPECT/CT MPI between July 2014 and February 2016 were retrospectively analyzed. Low dose CT attenuation correction was used during MPI. IEFs of lung, mediastinum and chest wall, large blood vessels, spine, and part of upper abdomen were recorded independently. All findings were divided into three categories: IEFs requiring further examination and treatment measures taken immediately (group A), IEFs requiring follow-up or further examination (group B), IEFs need no further treatment (group C).

Results
IEFs (n=356) were observed in 52.31%(272/520) of the patients, with 24 cases in group A (4.62%, 24/520), 105 cases in group B (20.19%, 105/520) and 143 cases in group C (27.50%, 143/520). There were 158 clinically significant IEFs in 129 patients (24.81%, 129/520), including 5(0.96%, 5/520) with newly diagnosed malignancy.

Conclusion
IEFs detected by CT used for attenuation correction during SPECT/CT MPI are not uncommon, including a few cases with clinically significant findings.

We have been facing Manchu at a post mother language stage. There were so many ethnic groups from ancient times in China,but it is rarely to see an ethnic group like Manchu to ponder and deal with the relationship with Han ethnicity. Manchu's speaking Chinese is the justification that it be treated as an ethnic of Chinesization. Mother language is not all of a national culture. The opinion that a minority ethnic group is self denial when changing to use Chinese is absurd. Based on Manchu's present state,some common sense on its spiritual type can be concluded,and the post mother language's cultural theme,is not belonging to Manchu itself.


A new work by the Spanish-Flemish master painter Fernando Gallego has been found in the church of Campo de Penaranda (Salamanca), where, in 1953, Manuel Gomez Moreno discovered his well-known Flagellation of Christ and a Nativity.


TRUST that my friend, Professor Raymond A. Bauer, will share with me not only the catchy title of his paper on "The Obstinate Audience,"' but that he will also let me draw some parallels between his analysis of the audience situation in general and that of a very special audience, the employee. It would appear that the employee as audience, as someone with whom management is trying to communicate, is becoming more obstinate than ever. We have communicated like mad at him. I'm afraid that he finished listening long before we stopped talking. TURNOVER AS INDICATOR The mute testimony to this state of affairs is the ever increasing rate at which employees resign or are dismissed. This problem is being faced by many businessmen, as well as by such other diverse employers as government, hospitals, and the public schools. The total turnover figure, which includes death, retirement, entrance into the armed forces, etc., is not as useful for our analysis as are the resignationdismissal components.


The strength of the ties of Soviet immigrants to the US Jewish community was assessed in a survey of 900 Soviet Jewish families living in 14 US cities. Being Jewish was very important to 57% of respondents and somewhat important to 28%; 90% would choose to be born Jewish if given a choice. 42% of immigrants considered themselves to be somewhat fairly or very religious at the time of the survey compared with 15% when they lived in the Soviet Union. 7% reported regular and 75% reported occasional temple or synagogue attendance in the US. Older respondents were more likely to affiliate with an Orthodox synagogue wheras younger respondents showed a marked preference for Reform Judaism. However less than 10% belong to Jewish fraternal or community organizations and the majority do not observe traditional religious practices. Respondents age 50 years and very consistently demonstrated stronger religious attachments. Although respondents indicated they would not encourage their children to settle in Israel the large majority want them to receive a good Jewish education affiliate with the American Jewish community and observe Jewish religious practices even in cases where the respondents do not. Later surveys should seek to examine Jewish identity and affilitation patterns among the younger cohort of Soviet Jewish immigrants.


Various neurodegenerative and psychiatric diseases are related with changes in spoken language [1], although they have seldom been investigated. We evaluate the effectiveness of our language‐agnostic Machine Learning (ML) system to detect subtle changes in spoken language that manifest early signs of cognitive decline, thus assisting with its diagnosis. We evaluate our methodology using recordings of speech samples from multiple languages obtained from patient cohorts in early stages of cognitive decline and matched healthy controls.


By the end of 1967, space diplomacy proved capable of accomplishing an international agreement at the speed of space travel itself. On the very last day before the end of its 22nd Session, the United Nations General Assembly was confronted with an Agreement on the Rescue and Return of Astronauts and the Return of Objects Launched into Outer Space and almost simultaneously adopted a resolution in which it "commends" the Agreement. What a United Nations Committee had not been able to produce in five years of hard work, emerged suddenly from private negotiations between the United States and the Soviet Union. Although many of the Agreement's particular provisions submitted by the two space powers had their origin in earlier texts discussed in the UN Outer Space Committee and its legal subcommittee, the fact remains that it was a bilateral draft which was rushed through the multilateral arena.


The research in this paper focuses on the core loss and rotor eddy current loss of high speed permanent magnet synchronous motor. The influence of stator outer diameter on core loss is analyzed. The effects of air gap width, slot width and jacket on rotor eddy current loss are studied. The winding copper loss and air friction loss are calculated and qualitatively analyzed, and the effects of rotor speed, air gap width, temperature and axial wind speed on air friction loss on rotor surface are analyzed. Finally, the loss distribution data are summarized, which provides a reference basis for motor thermal design.


Four new fluorocarbon surfactants were introduced, namely fluorocarbon sulfurous quaternary ammonium salt, fluorocarbon carboxylic betaine, 8-3-9 fluorocarbon-space-hydrocarbon Gemini surfactant,6-3-9 fluorocarbon-space-fluorocarbon Gemini surfactant, CMC of which are 1. 14×10-4 , 1. 12×10-3,4. 93×10-4 and 2.78 ×10-4 mol/L respectively. The surface tensions of the water solutions are 19. 0,22. 0,20. 9 and 22. 7 mN/m respectively at CMC, as well 16. 4,18. 2,19. 2 and 20. 4 mN/m respectively in 0.1% water solution. The relationship between the structure and property was illustrated in brief.


Abstract A total of 581 official test herds on the Quebec Dairy Herd Analysis Service were surveyed to measure frequency of practices of milking hygiene and effects of milking hygiene on herd averages of somatic cell counts and milk production. Over 99% of the dairymen washed or sprayed cows' udders, 55% used a separate towel for washing, 18% dried udders after washing, 35% rinsed teat cups in disinfectant, 50% used a teat dip, 34% recorded mastitis cases, and 63% had a mastitis control program, but only 18% had a program organized by a professional. Herds using a teat dip had counts 70,300 cells/ml lower than those not teat dipping, and herds drying udders had counts 44,000 cells/ml lower than those not drying udders. Effects of use of separate towels and rinising teat cups were small. Herds on a mastitis control program organized by a professional and those on a self-organized program averaged 58,800 and 40,800 cells/ml lower counts than herds without a control program. The difference between herds subscribing to a monthly cell counting service and those not was 30,400 cells/ml in favor of herds receiving monthly reports. Each increase of 100,000 cells/ml in herd average of cell count was associated with a decline of 59kg average production in the herd.


The functions of ectomycorrhiza,and the effect of environmental factors on ectomycorrhiza and ectomycorrhizal fungi are discussed. Some advice on the existing problems of ectomycorrhizal research at present in our country are put forward.


While there is an increasing realization of the potential that IT offers for human welfare, IT-induced productivity and growth are confined to the developed world. It is argued that even though the international digital divide is a reality, there are certain specific characteristics of the new technology that leave scope for mitigating, if not totally bridging, the gap when appropriate policies are in place.


Almost exactly at the mid-point of the seventeenth century the axe severed King Charles'neck. The sudden cease of majesty in 1649 was not only "the signal for an excited debate about what form of government might best succeed monarchy, and how authority might be reconciled with personal rights" 77 but also something desired by society and provoked by the dramatists since Elizabethan times. The imprisonment and murder of Richard II in Pomfret castle was its anticipation and premonition. The beheading of the king was the direct result of the Tudor and Stuart policy of extending the powers of the crown beyond acceptable limits. The theory of divine right was a natural ally of royal absolutism in politics for it placed the king legally and morally above all human law and restraint. It strengthened the right of the monarch to assert his authority without interference by Parliament or legal claim but eventually caused the disintegration of the hierarchical world when kings tried to retain the sacredness of status without fully accepting the sacred function and to impose their particular will and not the will of God. Under these conditions of despotism the Elizabethan world picture became less credible and more objectionable. The discrepancy between the ideal programme and the actual performance gave rise to a strong opposition and political awareness. The theatre became the popular dramatic framework to oppose the establishment. In this way Renaissance drama set out not only to teach and reflect reality but to change it. It was very conscious of the historical context. Therefore drama was more than just a literary genre. It was believed to be a powerful instrument for clarifying facts and opposing the present state of things. The theatre was for leisure and entertainment but also a place of social propaganda and political provocation since it was the


The design of an improved infrared reflection–absorption cell which facilitates the study of redox‐active chemical species is described. The modifications to existing cell designs permit (i) the sample to be cooled to temperatures limited by the characteristics of the solvent, (ii) the sample to be maintained under an inert atmosphere, (iii) the study of small (1–2‐cm3) volumes of solution, and (iv) the entire optical path to be maintained under vacuum. These features of the cell design facilitate the study of small quantities of compounds which are unstable with respect to reaction with oxygen, moisture, and redox partners. The study of tris‐maleonitriledithiolato complexes of chromium in formal oxidation states iv, v, and vi demonstrates the advantages of the cell.


This paper presents an overview of some key QoS features that will enable the DVB/DAVIC protocol with a superior performance and efficiency at the Media Access Control (MAC) layer for the support of delay-sensitive applications. We show the deficiencies of the basic reservation request mechanism provided by the DVB/DAVIC MAC protocol and present a performance optimisation via simulation results in terms of mean packet access delay and system throughput. Initial results show that the number of delay sensitive streams supported can be increased considerably by considering QoS features.

Scarcity of the spectrum is a major challenge that the wireless communication technology has to deal with in all respects. Cognitive Radio has suggested better spectrum utility nowadays. The primary user, in cognitive radio, is the licensed user of the spectrum. When primary user is not using the spectrum, the spectrum is free which can be accessed by the secondary user. This sharing of spectrum can be controlled by Cognitive Radio technology. In this paper, we introduce new sensing methods based on Eigenvalues of the covariance matrix of signals received at secondary users. There are two sensing algorithm options are existing based on Eigenvalue method, one is Maximum to Minimum Eigenvalue and second is Average Energy to Minimum Eigenvalue. For the analysis, we considered the Maximum to Minimum Eigenvalue based method. We propose Block Wise Eigenvalue based spectrum sensing algorithm with the aim of improving accuracy, speed and reduced computational complexity of sensing compared to existing techniques. The proposed method gives better performance than the ideal Eigenvalue based spectrum sensing when the signals are highly correlated. Simulations based on the randomly generated signal are presented to verify the effectiveness of the proposed methods.


Background and purpose:The prognosis of patients with FIGO stage I endometrioid adenocarcinoma is good, although the local control is high, some patients are not sensitive to the treatment and relapse. This paper was to explore the prognostic factors associated with recurrence and assess the efficacy of adjuvant chemotherapy in patients with the FIGO stage Ⅰ endometrioid adenocarcinoma. Methods:A retrospective analysis of 96 patients with FIGO stage Ⅰ endometrioid adenocarcinoma was performed. All patients underwent surgery, of which 17 patients underwent adjuvant chemotherapy. Multivariate analysis was performed for the prognostic factors and actuarial techniques were used for recurrence rates. All the patients were followed up and the mean time of followup was 43.6±24.0 months. Results:Ten of 96 cases with FIGO stage Ⅰ endometrioid adenocarcinoma were recurrent and the recurrence rate was 10.4%. The median time of recurrence was 17.3±8.0 months. The median age was 61.8±6.4 years in recurrent patients, which was higher than that of patients without recurrence (P=0.015). In recurrent patients, the percentages of stage Ic and G3 were higher than those of other stages and histological grades (P=0.011, P=0.000). Multivariate analysis showed that FIGO stage and histological grade were significant prognostic factors (P=0.013, P=0.000). The recurrent rate in patients with FIGO stage Ic who had received postoperative adjuvant chemotherapy was significantly lower than that of patients who had not undergone adjuvant chemotherapy (P=0.046). Conclusion: FIGO stage/depth of myometrial invasion and histological grade were important prognostic factors in FIGO stage Iendometrioid adenocarcinoma. It is possible that postoperative adjuvant chemotherapy might decrease the recurrence and improve the prognosis in patient with stage Ic.


A novel single-mode single-polarization (SMSP) photonic crystal fiber using resonant absorption effect has been put forward and analyzed for the first time, to our knowledge. A full-vector finite element method with perfectly matched layers is employed to investigate the characteristics of the fiber. The numerical results predict that very efficient SMSP operation can be achieved with both high bandwidth and high extinction ratio at low loss penalty. The effects of the fiber structural parameters have been explored, which will provide useful directions for the design and fabrication of the fiber. The research results will be instructive for the realization of new high performance SMSP fibers.

This study explores the learners' strategies for heuristic ability in mathematics at the secondary level. The study is qualitative, and the method adopted for obtaining information about the learner's strategies is a case study. The site selected is Govt. Girls Higher Secondary School Rustam, Mardan, Khyber Pakhtunkhwa, Pakistan. Participants of the study were six in number, selected from science group students of the 9th class based on their interests. A test of non-routine problems was used for the collection of data. Six non-routine problems were given to the students to check their heuristic ability. Non-routine problems were analysed through cognitive strategies. No scoring of students was considered in this study. The researchers categorized the learner's responses so that students who solved questions by applying complete strategy were marked with the word excellent, the half strategy was marked very good, and unsatisfactory solutions were marked satisfactory. The study investigated learners' strategies such as making tables, using formulas, guessing, making diagrams, doing trial and error, logical reasoning, non-logical reasoning and looking for patterns. Results show that students who are interested, motivated and have a positive attitude toward learning practice various methods for solving non-routine problems.


We analyzes what is reported in the literature respect to the relationship between self-esteem and addiction, starting from the observation that the acceleration given by technology increasingly highlights how much a strong connection is being created with psychological, sociological and pedagogical events that are updated and adapt to the change taking place. The expansion of Information and Communication Technologies (ICT) has led to numerous positive elements, including new means of communication, work, learning and entertainment. It has also show some problems associated with inappropriate or excessive use, like absenteeism at work and school, academic failure, deterioration of family or friendship relations and even health problems, particularly among adolescents (Munoz-Miralles et al. 2016). A factor that seems to be recurrent in cases of addiction is that related to self-esteem. Self-esteem is considered an important factor also in terms of resilience and physical well-being (Mariani, Marcolongo, Melchiori, Peluso 2019)
