Based on Gaia DR2 data and new CHIRON radial velocities, we have discovered that two nearby stellar associations UPK 535 (318.08 ± 0.29 pc, 25+15 −10 Myr, 174 stars) and Yep 3 (339.54 ± 0.25 pc , 45 +55 −20 Myr, 297 stars) in the Gum Nebula have recently collided. We project stars' current positions, motions, and measurement uncertainties backward and forward through time in a 10,000-trial Monte Carlo simulation. On average, the associations' centres of mass come within 18.89 ± 0.73 pc of each other 0.84 ± 0.03 Myr ago. A mode of 54 ± 7 close (<1 pc) stellar encounters occur during the collision. We cannot predict specific star-star close encounters with our current ∼7.6 pc distance precision and 21.5-per-cent-complete radial velocity sample. Never the less, we find that two stars in UPK 535 and two stars in Yep 3 undergo a nonspecific close encounter in >70 per cent of trials and multiple close encounters in ∼30 per cent. On average, the closest approach of any two stars is 0.13 ± 0.06 pc, or 27,000 ± 12,000 au. With impulse-tracing values up to 2.7+3.1 −1.1 M⊙ pc −2 km−1 s, such close encounters could perturb stars' Oort cloud comets (if present), cause heavy bombardment events for exoplanets (if present), and reshape solar system architectures. Finally, an expansion of our simulation suggests other associations in the region are also interacting. Association collisions may be commonplace, at least in the Gum Nebula straddling the Galactic plane, and may spur solar system evolution more than previously recognized.


The role of water in daily life, including activities in the mosque is very significant. The existence of the Ulul Albaab Mosque which is always busy with various congregation activities and activities carried out by students and the campus community affects the need for clean water. So far, the ablution used water at the Ulul Albaab Mosque has been dumped into the sewers. Measuring the quantity of water to determine the volume of ablution used water at the time of obligatory prayer is the first step to assessing its potential utilization. The number of congregation who perform ablution is directly proportional to the number of congregation of the Ulul Albaab Mosque. The average congregation of the mosque is 857 people/day and the average number who perform ablution is 778 people/day. The results showed that the volume of water used for ablution was 3.9 liters/person with an average time required for ablution of around 64 seconds. The use of recycling ablution water can be used for non-consumption needs.


A state-of-the-art flow lab-on-a-valve technique is reported incorporating integration of flow devices such as reaction and mixing serpentine coils and confluences into a monolith flow circuit mounted directly on an eight-port selection valve. The potential of the flow circuit manifold or chip-on-valve in combination with multisyringe flow injection analysis is demonstrated by the application to the successful determination of nitrite and nitrate in seawater. Characteristics and further potential of chip-on-valve are discussed. Due to preparation and fabrication by use of computer aided design, this chip design shows great potential for the automation of sophisticated flow networks in compact and robust flow circuits.


Surface x-ray diffraction has been employed to elucidate the surface structure of $\mathrm{Ti}{\mathrm{O}}_{2}(110)(1\ifmmode\times\else\texttimes\fi{}1)$. The atomic coordinates emerging from this study are in excellent agreement with those derived in other recent quantitative structure determinations of this surface. Most importantly, debate over the relaxation of the surface bridging oxygen has been resolved. In a previous surface x-ray diffraction study, it was concluded that this atom relaxes toward the bulk by $0.27\ifmmode\pm\else\textpm\fi{}0.08\phantom{\rule{0.3em}{0ex}}\mathrm{\AA{}}$, whereas in this present work we determined this displacement to be $0.10\ifmmode\pm\else\textpm\fi{}0.04\phantom{\rule{0.3em}{0ex}}\mathrm{\AA{}}$ away from the bulk, which is in accord with the results of other experimental techniques.


In this article the authors discuss some of the issues and controversies generated by the development of the overactive bladder symptom complex, the challenges in its clinical application and the current state of play with regards to pharmacotherapeutic management.


Disposition kinetic studies of gati fl oxacin (GAT) was conducted after single i.v. dose (10 mg/kg) in six healthy and six mastitic Black Bengal lactating goats. Mastitis was induced by coagulase positive S. aureus . The concentration of the drug was estimated by HPLC. The maximum milk concentration was found to be signi fi cantly (p< 0.05) higher in mastitic goats (12.78 ± 3.11 μ g/ml) than healthy (9.17 ± 1.41 μ g/ml). The therapeutic milk concentration in mastitic goats (0.13 ± 0.05 to 12.41 ± 2.99 μ g/ml) was maintained for 48 h which was signi fi cantly (p<0.01) longer than in healthy goats (24 h). The elimination half-life in plasma and milk of mastitic goats (5.82 ± 0.67 and 8.20±0.21 h) was signi fi cantly (p<0.01) higher than healthy (4.54 ± 0.75 and 3.67±0.09 h).It indicates that GAT persisted in the body of mastitic goats for a longer duration. The AUC milk /AUC plasma ratio was 5.82. The t ½ milk /t ½ plasma ratio was 1.41. MIC in this experiment was considered to be 0.1 μ g/ml. The AUC/MIC ratio of plasma and milk of mastitic goats were 180 and 1049 respectively. On the basis of the results obtained it was concluded that GAT exhibited improved pharmacokinetic parameters with good penetration and longer persistence in mastitic milk, which will be of great help in the treatment of mastitis in goats caused by S. aureus .


The distribution and dissociation equilibria of phase-transfer catalyst, trioctylmethyl-ammonium chloride (Q +Cl− ), for the system of QCl–toluene–aqueous HCrO4 − solutions were measured at 298K for the systems of toluene–water or –aqueous electrolyte solutions. The evaluated distribution coefficients of trioctylmethylammonium chloride and the complex formed between trioctylmethylammonium cation and HCrO4 − were correlated as a function of the ionic strength in the aqueous solutions. The dissociation constants, K 1 and K 2, were independent of ionic strength.

Abstract By exploring tactical and strategic uses of chemical agents beyond Agent Orange and the other 'Rainbow Herbicides' used as part of Operation Ranch Hand during the Vietnam War, this essay seeks to fill a gap in our under- standing of the chemical war waged by the United States in South-east Asia, and to make a contribution to the growing body of literature devoted to the intersections of military and environmental history. Taking seriously the roles played by both human and non-human actors, it explores how the White House and Pentagon continually attempted, unsuccessfully, to impose more stringent forms of control over southern Vietnam. Herbicidal warfare and the use of forest fire as a military weapon were simply two more failed attempts among many to impose control on a nation, a people, and a landscape — indeed, on nature itself — all of which refused to accept the dictates of American power just as stubbornly as American policymakers refused to accept the limitations of that power.


The results of surface-tension measurements for supercooled water are presented. A total of 702 individual measurements of surface tension of triple-distilled water were made in the temperature range, 27 to -22.2 C, with 404 of these measurements at temperatures below 0 C. The increase in magnitude of surface tension with decreasing temperature, as indicated by measurements above 0 C, continues to -22.2 C. The inflection point in the surface-tension - temperature relation in the vicinity of 0 C, as indicated by the International Critical Table values for temperatures down to -8 C, is substantiated by the measurements in the temperature range, 0 to -22.2 C. The surface tension increases at approximately a linear rate from a value of 76.96+/-0.06 dynes per centimeter at -8 C to 79.67+/-0.06 dynes per centimeter at -22.2 C.


The article takes a look at Ramon Muntaner's Cronica, other medieval chronicles y the diplomatic relations of the time in order to test their internal coherence. Indeed, all of these sources coincide in offering us an idea which characterises the policies of the House of Aragon in the Mediterranean as hostile to the axis of power which dominated the High Middle Ages, the royalty in Paris and the Holy See of Rome. Such hostility, however, contrasted with the religious function which the House of Aragon had itself. Thus, it was not hostility towards the Papacy, but rather towards the Papal dedication to the defence of French interests, above all in Sicily and Naples.


In this paper, the authors first study properties of measure of fuzziness, and obtain some significative conclusions, those should establish a base in perfecting theory of measure of fuzziness and how to select proper measure of fuzziness in application. In addition, this paper indicates nonconsitency of definitions of measure of fuzziness, and validates that fact using some examples. Finally, we give elementary theoretic analysis for possible negative influence from nonconsitency of definitions of measure of fuzziness, when theory of measure of fuzziness applies to image processing.

Experimental evaluation of a high-temperature superconducting Josephson heterodyne mixer based on a 'resistive-SQUID' configuration is reported. The device consists of two YBa2Cu3O7−x step-edge Josephson junctions connected via a small resistor in an otherwise superconducting loop. It has been previously shown to generate a heterodyne oscillation, which is frequency-tunable by a control current through the resistor. Under certain conditions, this device can operate as a frequency-tunable heterodyne mixer (down-converter) in the presence of an RF signal. In this paper, we describe the operation of the autonomous Josephson mixer–local oscillator device and present the experimental results on the mixer performances in terms of the junction current–voltage characteristics, the frequency tunability, linearity, and dynamic range as well as their temperature dependence for signal frequencies from 1 to 5 GHz.


The bonding of brackets is an essential part during the course of orthodontic treatment. A good bonding between the brackets and enamel surface is highly anticipated in the orthodontic treatment period with dynamic state. Debracketing at the end of orthodontic treatment is the critical moment for making a perfect endpoint. 4-META with superior bonding forces is an adhesive material commonly used in clinical practice. However, a good bonding force can cause increased difficulties in clinical practice and even result in pain or discomfort during the debracketing procedure. Therefore, this study aimed to find ways to reduce bonding forces during debracketing for the ultimate purposes of reducing the difficulties in clinical practice, as well as to eliminate pain and discomfort for patients. Super-Bond C and B (Sun Medical Company, Kyoto, Japan) as an adhesive resin in combination with metal brackets (Tomy Company, Tokyo, Japan) was used for bond strength tests in the present study. Fifty human premolars extracted due to orthodontic treatment were collected, randomly divided into five groups and immersed in different reagents as follows: no treatment (control group), ethanol (experimental group 1), eucalyptus oil (experimental group 2), peppermint oil (experimental group 3) and hot water (experimental group 4). After 10 min of immersion for each group, the specimens were subjected to debonding tests using a material testing machine (Model JSV H1000, vertical, an automated test station utilizing the features of Handy Force Gauge (HF-100)). The distributions of residual resin were examined by an optical microscopy after debonding and then analyzed according to the recorded Adhesive Remnant Index (ARI) score. The results showed that the bonding forces of 4-META / MMA-TBB resin was reduced to the lowest level after 10 minutes of immersion with eucalyptus oil (experimental group 2). In comparison with the control group, there was a statistically significant difference (experimental group, 2: 8.88 ± 2.61 Mpa vs. control group, 13.81 ± 3.04 MPa). Peppermint oil (experimental group 2) also caused reduction in the bonding forces but less effective than eucalyptus oil. Ten minutes of immersion with ethanol or hot water showed no effect on the bonding forces for Super-Bond C and B resin. There was no difference in the distributions of residual resin among all groups. The use of chemical reagents could lead to a reduction in shear bonding forces of orthodontic resin. However, more in-depth studies are necessitated to compare with the other reagents and improve formulations so that can be used in the mouth.

I S THE TASK OF THE BIOGRAPHER synonymous with the task of the historian? The answer, of course, depends on our definition of historical inquiry. If we assume that the study of history involves simply the reconstruction of the past, the illumination of human experience in all its variety and nuance, then the study of any individual is a contribution to historical understanding. But there is another, broader conception of the historian's task: the belief that the purpose of scholarship is not simply to reveal the past, but to explain it; to make connections and identify transformations; to look at the individual pieces of history in terms of how they fit into a larger pattern. By that definition, the connection between biography and history becomes less clear, and all historians engaged in biographical inquiry must grapple with an important question: how does the study of individual lives illuminate the larger history of a society or an era? There is no additional question facing those historians whose excursions into the field of biography take them into the lives of more than one person: what can they study of several lives, juxtaposed against one another, teach us that an ordinary biography, or another mode of analysis, can not? My own work in the field of what some have called "comparative biography'" has forced me to confront both these questions and has led me to answers that have discomfited some traditional biographers but that suggest, I believe, several avenues for enhancing the connection between the study of individuals and the illumination of the larger patterns of the past.


The temperature dependence of the parallel and perpendicular susceptibilities of an antiferromagnetic KCoF 3 single crystal has been obtained from the shift of 19 F NMR and the static magnetic measurements in both the paramagnetic and antiferromagnetic states. A large residual value of the parallel susceptibility, (4.6±0.1)×10 3 emu/mole, is observed even at 4.2 K, which is ascribed to the residual orbital momentum of Co 2+ ions. The absolute value and the temperature dependence of the susceptibility are in general accord with the theoretical prediction by N. Suzuki, T. Isu and K. Motizuki based on the correlated effective field approximation.


This paper utilizes computational modeling techniques to simulate cardiac tissue conduction. The heart is a complex system designed to convert electric signals into mechanical forces that pump blood throughout the body. The myriad of interactions among the myocytes are difficult to study in vivo and are ideally suited to examination using computational techniques. Cellular automata (CA) is the computational tool utilized by the authors to model cardiac ventricular conduction. The electric activity of the heart is modeled using a set of rules that defines the changes in electric potential of individual myocytes. The myocytes are represented by "cells" that interact with other myocytes in their local neighborhood. The model is implemented using a publicly available software package, NetLogo, produced by Northwestern University. This CA model of electric activity of the heart successfully reproduces the normal spread of electric impulse in the heart as well as tachyarrythmias generated by a prolonged QTc. Introduction: The heart is a finely tuned organ that requires coordinated activity amongst tens of millions of individual myocytes to generate adequate pumping pressure; that this coordination is achieved entirely via local intercellular interactions is phenomenal. The spread of electric activity through cardiac tissue is the main mechanism by which the coordination occurs. The cardiac conduction system is composed of pacemaker cells, specialized conduction cells, and myocytes. Under normal conditions, the signal to contract is generated by the sinus node in the right atrium. This signal is conducted to the cells of both the right and left atrium and enters the atrioventricular (AV) node. The AV node slows conduction to allow the atrium time to finish contraction, thereby maximizing the filling of the ventricles. The AV node then initiates conduction of signals to both ventricles via the right and left "bundle branches". This signal initiates contraction of both ventricles, starting from the bottom, anatomically maximizing the ejection of blood into the pulmonary and systemic circulation by pushing the blood from the blind end of the ventricles towards the pulmonary Figure 1: The 4 phases of a ventricular myocyte action potential


A fragmentary large chlorite vessel of the Halil Rud valley civilization (Kerman, Iran, mid third millennium bc), found in unknown circumstances and recently recovered by the police forces of Iran, is discussed in the wider scenario of coeval animal iconographies of middle and southwest Asia. Beginning from the imagery carved in the two superimposed friezes of the reassembled fragments, we review the different theoretical approaches in interpretation of similar animal iconography. The figuration of the vessel is interpreted as a scene of the scavenging of bovine carcasses by three different animal actors: lions and birds of prey/vultures, but also hyenas—a subject previously unknown in the art of the reference regions. Following a review of the interrelations of these species in scavenging and with humans, particularly in the coeval context of domestic animal exploitation and developing urban settlement, we investigate the potential semantic implications of the iconography in terms of the symbolism and ideology in the social context.


Regular works of maintenance in power systems are necessary to guarantee the supply of energy, what causes, unavoidably, the outage of its equipments. This activity is known as scheduled outage, being its procedures based on the planning engineers' knowledge and experience. The changes in the electric system, as a consequence of the maintenance planning, can lead to an unexpected behavior with possible new emergency situations for the dispatchers. In this context, there is not an explicit criterion to evaluate in a wider way the quality of the results of an outage programming. The present work describes the studies on an expert system having as objective to associate the engineers' practical knowledge to the severity ranking of the possible critical emergencies through automatic contingency analysis. It is expected that the demonstration of the feasibility to obtain and apply these indexes allow the future development of an evaluation criteria that will support the analysis done by the engineers involved with scheduled outage.


Linguistic characterizations of English stress patterns typically claim that when one stressed syllable is followed immediately by another and the rhythmic clash is not corrected by retracting the first stress to an earlier position, then the first vowel will be protracted, increasing the phonetic separation between the adjacent beats and thereby regularizing the rhythm. Acoustic studies, however, consistently show that the mean duration for the first vowel in such a stress clash is not substantially longer than that of its counterpart in an alternating stress pattern. Examination of articulatory correlates suggests an explanation for this discrepancy: Syllables in a stress clash may undergo a rhythmic reorganization of segmental gestures that can distance the first syllable's prosodic peak from the following stress without lengthening the vowel's measured duration. Displacements, durations, and peak velocities of jaw opening and closing gestures were measured for four speakers' productions of stress clas...

In this research, polyurethane (PU) and polyurethane/silicone (PU/silicone) coated fabrics were manufactured and the effects of coating parameters such as coating material, coating technique, and production parameters on sewing performance of the coated fabrics were investigated. During manufacturing processes, one fabric sample having cotton as raw material and having plain weave was used as the base fabric. The base fabric was coated with two coating materials as PU and PU/silicone by two coating techniques such as rotary screen coating and blade coating with systematically changing production parameters (screen pressure and contact angle). Therefore, twelve coated fabric samples having different technical specifications were produced. Due to the limited number of studies in related literature, sewing performance of the coated fabrics was investigated by the tensile properties of the unsewn and the sewn fabrics and also the seam efficiency values were compared. Variance analyses were used to determine and evaluate the effects of coating parameters on seam performance of the coated fabrics.


This paper considers the application of self-tuning digital PID controllers for process control modelled by delta models. The process is identified by the regression (ARX) model using the recursive least squares method (RLSM) with LD decomposition and applied directional forgetting. The basic RLSM algorithm has been modified for the delta model structures. Controller synthesis is designed by method where the required transfer process behaviour of a 2DOF closed control loop can be achieved by selecting our own circular frequency ωnand relative damping ξ in the characteristic equation for connected second-order plants, second controller synthesis is designed by poleplacement method.


Narrative films are not factual films-even when they purport to divulge the true-life stories of real people. Whether their subjects are sports figures, show business personalities, or world leaders, such movies are often rife with misinformation. But unless their function is to propagandize, they are not purposefully fashioned to toss the viewer curveballs and spitballs. They exist as entertainments, not as historical records.1The above observation references The Winning Team (1952), a Hollywood biography of Hall of Fame hurler Grover Cleveland Alexander. But it holds true for biopics released across the decades, and it certainly relates to Eight Men Out (1988), directed and scripted by John Sayles and based on Eliot Asinof 's celebrated chronicle of one of the most notorious episodes in baseball history: the 1919 Black Sox scandal. The tainted Black Soxers also appear in Field of Dreams (1989), based on W.F. Kinsella's novel. Field of Dreams is the It's a Wonderful Life of baseball films: a wistful fantasy about love, dreams, and the timelessness of the game. The scenario deals with the scandal from a wholly different perspective than Eight Men Out, with the defamed ballplayers restored to their glory when their spirits come to play in an eternal, pastoral ballfield. But there are no facts with which to quibble about in Field of Dreams. Even though the film features depictions of real-life athletes-from the Black Sox players to Archibald "Moonlight" Graham, the notable one-game major leaguer-Field of Dreams is a fantasy.But Eight Men Out is not presented as make-believe. Nor is it adapted from a novel. Sayles's film purports to be factual, yet it features a number of verifiable errors. Some literally are of the did-he-throw-left-handed-or-throw-right-handed variety. For example, pitcher Dickie Kerr (played by Jace Alexander), who in 1919 was a White Sox rookie, was a left-hander. However, 61 minutes and 50 seconds into the film, he is shown warming up right-handed. Then, 15 seconds later, Kerr informs Kid Gleason ( John Mahoney), his manager, that he recalls the first major league game that he attended. His grandfather took him and, in it, Gleason not only bested Cleveland's Cy Young in a 1-0 thriller but tossed a no-hitter. Kerr was born in St. Louis in 1893. Gleason (who played in that town from 1892-1894) leftpitching for good in 1895; he spent his final years as a big leaguer mostly at second base. So it is unlikely that Kerr would have recalled seeing Gleason pitch. Plus, there is no record of Gleason hurling a no-hitter, against Cy Young or anyone else.2 In the film, fielders play with their index fingers extending outside their gloves. Hap Felsch (Charlie Sheen), for one, is depicted as such at 48 minutes, three seconds. Yet there is no evidence that big leaguers followed this practice in 1919; they did not do so until the 1950s. Willie Mays biographer James S. Hirsch writes, "When Mays entered the big leagues (in 1951), fielders kept all their fingers inside their glove. But Mays realized that he could control the glove better by sticking his leftindex finger outside the mitt. He doesn't claim credit for starting the trend, but eventually most players had their index fingers outside as well."3A number of slip-ups are found in the Sayles depiction of Game One of the 1919 series. Before the start of the contest, 43 minutes and 38 seconds into the film, "Sleepy" Bill Burns (Christopher Lloyd) and Billy Maharg (Richard Edson), who played key roles in arranging the fix, are seen settling into their seats in the Cincinnati ballpark. Yet neither of them attended the game. 4 At 48 minutes and 27 seconds, the ballyard scoreboard is shown. It is the bottom of the fourth inning and the score is Cincinnati 1, Chicago 0. The Reds tallied one run in the bottom of the first, which is accurately represented, but the White Sox responded by tying the score in the top of the second. So at this juncture, the score should be 1-1. …


verted into productive grasslands with no erosion. In many areas the original desert grassland plant communities have changed in this century from grass to shrubs, trees, and cacti. In these areas Lehmann lovegrass may be the only perennial grass able to compete with the woody vegetation and persist over time, producing herbaceous forage for livestock and wildlife and providing cover to protect soils from erosion. Lehmann lovegrass has its place in southern Arizona's rangelands. It is here and land managers need to learn to take advantage of it where it presently occurs and try to limit its encroachment into the native grassland areas to protect their richness, diversity, and productivity.


Despite the high expectation for the shareholder derivative action to play an important role in improving corporate governance in China, only one lawsuit has ever been brought since it was formally introduced in 2005, so far as listed companies are concerned. Above all, the 1% minimum shareholding that plaintiffs are required to satisfy by law is a barrier to derivative suits. However, it is impossible to establish and reduce the threshold figure to an appropriate level, and actually the minimum shareholding requirement as a mechanism for screening out frivolous litigation is inherently flawed. On the other hand, the nature of the derivative action determines that the strategy based upon judicial control rather than a minimum shareholding requirement cannot work properly in China, where the judiciary is weak, unsophisticated and riddled with corruption. When the judicial system is in such a state of condition, it is unrealistic that the derivative action — and, indeed, the private enforcement of law in general — can play a significant role in corporate governance. The findings in this paper raise a question of how corporate governance can indeed be improved in a country where the judiciary is incompetent to perform its role.


In transport applications, electrical machines (EMs) are required to be highly reliable, in order to fulfill the intended mission profile over the expected lifetime. This task has been conventionally addressed through the adoption of safety-factors that might lead to an over-engineered EM. Only recently, few works have started championing a paradigm shift towards physics of failure methodologies, which allow to achieve an appropriate trade-off between optimal performance and demanded reliability figures. Thus, this paper proposes a reliability oriented methodology for low voltage (LV) EMs and outlines its critical implementation steps. Accelerated thermal aging (ATA) tests are preliminarily performed on custom made samples to assess the aging trend of the inter-turn insulation. The thermal endurance graph at different percentile values is then determined and a lifetime model suitable for variable duty motors is developed. Finally, this model is used to predict the inter-turn insulation cycles-to-failure of an EM installed on full-electric vehicle.


The essay deals with the complex issue of voluntary formalism, regulated in the articles 1326 paragraph 4 and 1352 of the Italian Civil Code, and the exegetical problems connected to it. The study aims to verify whether the voluntary formalism occupies the same role or not and fulfills the same functions as the legal formalism. Then the relationship between the voluntary forms and the classic pathologies related to contracts has been investigated in order to verify the possibility of tracing the whole theme of the forms chosen by the parties within the different problem of the formation of the contractual agreement.


The 2010 Cornell High Energy Synchrotron Source (CHESS) Users Meeting, organized by Detlef Smilgies, Chae Un Kim, and Kathy Dedrick, took place at Cornell University in Ithaca, NY on June 8-9, 2010, with 123 people in attendance. User Committee member Bruce van Dover (Cornell) presided over the first session.


The objective of this research is to determine the influential proportion of sweet potato Subgrade frozen usage as the substitution material toward the production of an extract product snack by using corn grits and rice. The parameters examined were organoleptic characteristic and proper analysis of financial. The organoleptic analysis comprises taste, crispiness, appearance, color, and aroma. The chemical analysis includes sucrose, water, and essence, as well as protein content. The result of this research shows that organoleptic testing toward the taste of an extract product snack by using Beni azzuma sweet potato s ubgrade indicates that the combination treatments give a positive influence toward organoleptic characteristics of the product. An extract product of snack product from Beni azzuma sweet potato Subgrade as the substitution material with 95% rice formula and 5% Beni azzuma sweet potato Subgrade is chosen as the best product for having the highest weight or quality, 0.970. Proper analysis from the snack processing is shown by NPV score, Rp. 2.,016,418,748 (bigger than zero), the IRR score is 50.00% (bigger than deposit interest, 12.56%). The investment expense needed for constructing the unit of an extract product snack processing with Beni azzuma sweet potato Subgrade as the substitution material is Rp. 330,978,230. The investment will be back after 3 years 5 months, and every year the project can give the profit of 50% from the investment expense.


The throwing power of various nickel plating baths were measured by the Hull cell method, in which throwing powers were expressed in terms of thickness of deposits measured at various points across the cathode, and of primary current distributions derived from the conventional Hull cell current density formula.The effects of current density and of bath compositions on the throwing power of nickel were studied. Among the nickel plating baths, studied, the highest throwing powers were given by dull nickel, all-chloride, NaCl, and high-sulfate nickel solutions. However, Watts, sulfamate, high-sulfamate, and KCl nickel plating baths gave moderate throwing powers, and fluoborate and citrate baths gave low throwing powers.The effects of sulfates on the throwing power and electrolytic conductivity were studied in the Watts bath. It was found that the throwing power and conductivity were improved by raising the concentration of sulfate such as K2SO4, Na2SO4, (NH4)2SO4 and MgSO4.

Despite the tremendous progress made in learning-based depth prediction, most methods rely heavily on large amounts of dense ground-truth depth data for training. To solve the tradeoff between the labeling cost and precision, we propose a novel weakly supervised approach, namely, the Guided-Net, by incorporating robust ground control points for guidance. By exploiting the guidance from ground control points, disparity edge gradients, and image appearance constraints, our improved network with deformable convolutional layers is empowered to learn in a more efficient way. The experiments on the KITTI, Cityscapes, and Make3D datasets demonstrate that the proposed method yields a performance superior to that of the existing weakly supervised approaches and achieves results comparable to those of the semisupervised and supervised frameworks.


Psychology teaching was implemented in virtue of excellent psychological movies, which not only could help to stimulate students' interest, and make the abstract theory concretion and visualization, but also provide the scenes similar to the reality for students' learning with attempts to improve their learning achievement. However, as for the exhibition of psychological phenomenon, psychological movies had its own limitations, and the teaching process was relatively time-consuming. Therefore, it was only applied as one of the teaching assistant forms.


: A pair of unique diastereoisomers of norlignan glycosides named cephalotanols A ( 1 ) and B ( 2 ), together with two known compounds, have been isolated from the twigs and leaves of Cephalotaxus fortunei Hook. Their structures were elucidated by using a combination of spectroscopic techniques and comparison of experimental and calculated electronic circular dichroism (ECD) data. To our knowledge, cephalotanols A and B represent the first rearranged norlignan glycosides with diphenylvinylcyclopropane core found in natural sources, of which biosynthetic pathways originating from co-occurring precursors 3 S -4  - O -  - D - glucopyranosylhinokiresinol ( 3 ) and 3 S -4  - O -  - D -glucopyranosylhinokiresinol ( 4 ) via di-  -methane rearrangement is proposed.


Background: The COVID-19 pandemic has deeply affected medical practice, and changes in healthcare activities were needed to minimize the overload and avoid healthcare systems collapse. The aim of this study was to evaluate the impact of the pandemic on surgical procedures in Brazil. Materials and Methods: We conducted a descriptive study of the number of hospitalizations for surgical procedures in Brazil from 2016 to 2020. Data were collected from the Brazilian Department of Informatics of the Unified Health System (DATASUS). Analyzes were performed according to the type of procedure, geographical region, subgroups of surgical procedures, and the number of surgeries from 2020 were compared with the average from 2016 to 2019. Results: There were 4,009,116 hospitalizations for surgical procedures in the Brazilian Public Health System in 2020. When comparing it to the average of hospitalizations from 2016-2019, there was a decrease of 14.88% [95%IC (14.82-14.93)]. Decrease rates were 34.82% [95%IC (34.73-34.90)] for elective procedures and 1.11% [95%IC (1.07-1.13)] for urgent procedures. Decrease rates were similar in all the five regions of the country (average 14.17%). Surgical procedure subgroups with the highest decrease rates were endocrine gland surgery (48.03%), breast surgery (40.68%), oral and maxillofacial surgery (37.03%), surgery of the upper airways, face, head and neck (36.06%), and minor surgeries and surgeries of skin, subcutaneous tissue and mucosa (33.16%). Conclusion: The overload of healthcare facilities has demanded a reduction of non-urgent activities to prevent a collapse of healthcare systems, resulting in a decrease in elective surgeries. Recommendations about the performance of surgical procedures were made, and continuous refinements of these recommendations are encouraged.

The invention discloses a method for saving power for a mobile data card based on traffic monitoring. The method includes regularly measuring network traffic when network connection is available; enabling the mobile data card to enter a power saving mode when the network traffic is lower than a threshold value; starting a network application monitoring module only when the current network traffic is larger than the threshold value; continuing measuring the network traffic regularly when network application is judged to be carried out; disconnecting network connection when the network application is not carried out at the moment; and enabling the mobile data card to enter the power saving mode. When a user uses the mobile data card, requirements of the user are automatically met by means of the traffic monitoring, network connection and working state of the mobile data card are automatically controlled, a power saving effect is achieved, power service efficiency is improved, and the problem of overheating caused by long-term operation of the mobile data card is avoided.


Background: An increase of sedentary behavior was observed in each year especially in clinical year. This accounts for a decrease in physical activities (PAs) of medical students, which could lead to reduced overall health and physical performance.

Objective: To compare the levels of PA between pre-clinical and clinical medical students of Mae Fah Luang University (MFU) and to explored association between the levels of PA and school year.

Materials and Methods: A cross-sectional study was conducted between May and August 2019. Online questionnaire, including personal profiles and global PA questionnaire, were distributed to all MFU medical students currently studying in the academic year of 2019.

Results: One hundred fifty-six medical students participated in the present study. From the questionnaires, 67.74% of pre-clinical medical students (n=63) and 52.99% of clinical medical students (n=36) had moderate to high levels of PA. Pre-Clinical students had significantly higher levels of PA by median metabolic equivalent value (MET) at 1,908.73 versus 1,339.05 MET-minutes/week (p=0.03). The sixth-year medical students increased risk of lower PA than the first year about 8.34 times (p<0.01).

Conclusion: One-third of the medical students reported as having low levels of PA. Clinical medical students had reduced levels of PA compared to pre-clinical medical students. Therefore, PA should be promoted to help increase the overall health of medical students.

Summary Haemophilic arthropathy is a defining feature and a debilitating condition of persons with haemophilia (PwH) in low resource countries. Orthopaedic surgery is unavoidable for patients with high occurrence of joint damage. Aims: We aimed to evaluate the spectrum and outcome of invasive orthopaedic therapies in PwH and von Willebrand diseases (VWD). Patients and methods: Our descriptive observational retrospective study included 131 invasive surgical procedures, performed on 76 consecutive patients, most of them (93.4%) with severe disease, treated in Timisoara's Haemophilia Center over a period of 12 years; 17.1% had pre-operation anti-FVIII inhibitors. Invasive elective procedures were predominant (90.8%) as compared to emergency measures (9.2%); according to their invasiveness, 20.6% of interventions were major, 44.3% intermediate and 35.1% minor. Results: were good in the majority of cases; significantly reduced joint bleed rate and pain score were the most consistent achievements. The greatest proportion of complications occurred after major (66.7%), compared to moderate (25.6%) and minor (7.7%) interventions. The main threatening complication was the development (3.8%) or increase (4.6%) of inhibitor titer. Local bacterial infections and wound dehiscence complicated the evolution in 4.6% and 0.8 % of cases, respectively; we noticed no blood-borne infections or thrombotic accidents. Low dosage (10.7%) and short duration of substitution (21.4%) led to increased post-surgical bleeding and post-haemorrhagic anaemia. Conclusions: Surgery is a highly demanding intervention in haemophilia, which cannot be ignored in a low resource country. It represents a life or limb-saving and quality of life-improving measure.


Release of a mature egg is an important pre-requisite of mammalian reproduction.  Starting from the time when oogenesis begins during fetal development, to the time of puberty and until fertilization, the oocyte encounters several stop-and-go periods. Altered pathways may affect fertilization outcome. Understanding of the stop-and-go periods is based on exploring the underlying mechanisms. This review aimed at addressing the triggers and signalling pathways leading to oocyte meiotic II resumption. A detailed literature search was done for studies on various databases such as Google, PubMed/MEDLINE, Cochrane reviews etc.with related keywords such as oocyte meiotic release, oocyte metaphase arrest, oocyte activation, sperm oocyte activating factors etc. Selected studies were reviewed by two observers. All obtained information was analysed and was shaped into manuscript appropriately. It was explained that till ovulation begins oocytes are held in meiotic arrest in diplotene stage of prophase I. Just before ovulation luteinizing hormone (LH) surge directs resumption of meiosis I. The arrested primary oocytes complete meiosis I and progresses through second meiotic division and gets arrested again at metaphase II (MII) until fertilization. Results concluded that the MII arrest persists till sperm enters the oocyte and releases its activating factors into the ooplasm. These activating factors are the triggers unlocking the subsequent pathways releasing oocyte from meiotic arrest.

HE general supposition of international politics is that the situations or issues that are important and deserve study and analysis are those which bring states into sharper conflict, or into closer association, with each other-situations or issues, in short, which affect inter-state relations. Whereas the supposition of political economy, including international political economy, is that the issues and situations that areimportant and deserve study and analysis are those that seem likely to affect not just the distributive or who-gets-what character of the system but also its general stability, its perceived equity, its efficiency in producing wealth and the balance of power and influence over its future destiny. There seem to me, as I have argued in the preceding article, good reasons for directing attention to the politics and technology, as well as to the economics, of specific sectors of international political economy. The present article is an attempt to show how this might be done with a particular international sector or market, using shipping primarily as a demonstration model. At the same time, there are special additional reasons why shipping deserves more attention from analysts of the international system than it has so far received. In every political economy of any size, analysis must start with the two basic matters of security and money. How a political economy is organised to limit or prevent its own disruption by conflict, whether external or internal, and how it is organised to provide the monetary media for economic transactions-these are the key questions that affect all other activity and argument within it. In the eighteenth century, when political economy was first elaboirated, these two questions were called the 'safety of the realm' and 'the value of the currency'. Now we talk about the security system and the monetary system. But next to them, and also part of what we might call the social, political and economic infrastructure of a political economy, is surely its system of transport and communication. The truth of this has certainly been recognised by every imperial power as far back as the ancient world. A first and last concern has been to use road, rail or shipping routes to knit together outlying parts with the centre. Federal states have shown a similar concern with transport and com-


Fluctuations exist in the harmonic distortion of audio magnetic heads, presumably due to the "magnetizing curve disaccommodation" of the head core material. The fluctuations are most pronounced when the signal field intensity is suddenly varied. This behavior was experimentally investigated by using simple distortion measuring methods. The fluctuation is observed in both record and playback heads. Although the measuring methods may not indicate absolute distortion, the differences among various kinds of head core material are clearly shown.


Objective To learn about the prevalence of knee osteoarthritis among elder people in the suburbs of Shanghai and to compare it with that of the urban areas of Shanghai. Methods A total of 3 343 elderly aged from 60 to 98 in Yongfeng community in the suburbs of Shanghai were investigated via both physical examinations and questionnaire. Results Incidence rates of knee osteoarthritis were significantly different between males and females(P0.01);also incidence rate of OA increased with age among the aged population(P0.01).Incidence rates of knee osteoarthritis diagnosed by clinical findings and by X-ray were significantly different(P0.01).Both clinically diagnosed and X-ray diagnosed OA incidence rates among elder people were significantly different between the suburbs and the urban areas(P0.01). Conclusion The prevalence rate of knee osteoarthritis among elder people is higher in the suburbs than in the urban areas.higher in females than in males,and increases with age.Early interventions are needed especially in females living in the suburbs.


AIM: To investigate the effect of intraventricular pressure change by volume overload (VOL) on expression of proto-oncogene c- fos ,c- jun ,c- myc and egr-1 . METHODS: Left ventricular systolic pressure(LVSP) and left ventricular end diastolic pressure (LVEDP) of rat with VOL induced by aortacaval fistula operation and rats of control group were measured at 30 min, 1, 4, 6, 12 and 48 h after the operation,these mRNAs at the foregoing time points were measured by slot bloting method and quantified with densitometry. RESULTS: Be compared with the control group, VOL rats LVSP decreased ( P 0.05) and declined most remarkably at 48 h,LVEDP elevated significantly at 30 min ( P 0.05), reached a maximal value at 12 h and the levels of control group at 48 h ( P 0.05) after the operation.The proto-oncogene expression signals were not detected in the control,negative controls and VOL rats at 30 min after the operation. The c- fos, c- jun and egr-1 mRNA signals appeared earlier,at 1 h, and c- myc mRNA increased later at 4 h.All reached peak value at 4 h and then declined gradually.The c- fos mRNA were not detected at 48 h. The c- myc ,c- 0jun and egr-1 mRNA persisted throught the entire observation period from 1 h to 48 h. CONCLUSIONS: During VOL early phase the overload have effect on expression of the proto-oncogene mRNA,c- fos, c- jun and egr-1 mRNA appear earlier, c- myc later, egr -1,c- jun and c- myc persist longer period, but the expressions do not strengthen with the ventricule wall load increase.This sequential induction pattern may reflect the time course regularity of the proto-oncogenes expression induced by VOL,and indicate the proto-oncogenes expression initiate while the heart load accumulate some extent and duration and the load magnitude may not play a critical role.

Helminthiasis is among the most important animal diseases inflicting heavy production losses. The disease is highly prevalent particularly in third world countries (Dhar et al., 1982) due to poor management practices. Chemical control of helminthes coupled with improved management has been the important worm control strategy throughout the world. However, increasing problems of development of resistance in helminths (Geert and Dorny, 1995; Coles, ISSN: 2319-7706 Volume 2 Number 1 (2013) pp. 66-79


In recent years, insider threats within computers have been overgrowing because a high quantity of malware and its variants have been spread massively by spam mail, malvertising attack, and users' carelessness. Moreover, some of the dormant malware would not be inspected by ant-virus software, and the risk exists continually until finally becoming a disastrous economic loss. Several studies developed signature-based methods to detect insider threats, but we are more interested in how to simplify the network behavior from sophisticated traffic flow. Without inspecting network payload and packet with time-consuming, we focus on the traffic behavior that we only consider the features of source IP, destination IP, timestamp of connection, and quantity of connection. To conquer the black box of complicated network traffic, this work applies the deep learning paradigm and proposes the variant version of VGG16 to examine the features within traffic flow. Finally, this paper proposes a method to support more explanation on traffic behavior with learning model.


Measurements of the b axis dielectric and pyroelectric constants of the diacetylene monomer 1,6-bis(2,4-dinitrophenoxy)-2, 4-hexadiyne (DNP) have been made in the temperature range 10-300 K. A transition from a high temperature nonpolar state to a low temperature polar state accompanied by an anomaly in the dielectric constant is observed at 31 K. The effects of solid state polymerization of DNP are reported where the transition is found to be suppressed with increasing polymerization.


More effective and efficient methodology for control education is desired, so that more people understand the control theory and that research achievements on control can be applied more easily. As an introductory part of such methodology, some basic experiences should be given. Therefore, we propose two control experiments; One is to understand phenomena such as steady state error and overshoot through tuning PID controllers. The other is to understand mechanisms of control equipments and those connections. The effectiveness of the proposed method is examined via the questionairs to students.


Natural biological systems make use of capillary-type hierarchical structures in order to enhance surface functionality within limited size. This paper discusses fabrication of similar synthetic structures by grafting carbon nanotubes (CNTs) on microcellular substrates such as graphitic foam. A major hurdle so far had been deposition of dense CNT layers inside uneven pores. This has been overcome in this study by pre-coating the porous surface with plasma-derived silica molecules. It is seen that the pre-coating not only increases the density of nanocatalyst attachment on the surface but also makes each nanocatalyst more effective in nucleation and growth of nanotubes. The CNT layers formed are strongly attached to the substrate, which makes them particularly suitable for use in robust hierarchical devices in the future.


In this paper, we explore methods for improving the automatic classification of schematic metonymies in corpus-based text. Using a pre-existing dataset of thousands of samples, we formulate the hypothesis that a better modeling of the underlying syntactic, semantic and conceptual meanings within a document (sample) can aid automated metonymy classification. To test this hypothesis, we build upon previous researchers' work on metonymy resolution systems but also introduce novel features, including, but not limited to, the extraction and analysis of conceptual paths between syntactically and semantically connected words. We initially explore three models for this classification task, but settle for final evaluation on two of them. Purely quantitatively, the results indicate that more work needs to be done, but on a more detailed analysis, we explain the strengths of our ideas behind our methods, and the weaknesses of the databases used for feature extraction. Finally, we present ways that this work can be continued and expanded. ∗This work was completed in partial fulfillment of the requirements for an Honors Bachelor of Science Degree in Computer Science from the Department of Computer Science at the University of Rochester, in Rochester, NY, USA.

In a previous issue of this journal, John Coleman (2004) reviewed the written-up version of a poster I presented at the 15th International Congress of Phonetic Sciences, Barcelona (Battaner-Moro 2003, henceforth BM). The aim of the poster was to discuss the evolution of Firthian prosodic analysis. In his review, Coleman derives from it 'an ignorance or a neglect of Firth's publications prior to 1948' on my part (p. 211). He focusses his criticisms on the following three statements: 'Firth never did prosodic analysis.' 'There is a complete absence of programmatic work in Firth's works.' 'Prosodic analysis was developed by the members of the London School and not at all by John Firth.'

In this paper a technique is proposed that largely corrects for the effects of non-stationarity in purchase incidence studies that use the Negative Binomial Distribution model. With non-stationarity controlled in this way, it is possible to assess the validity of the NBD mode% remaining assumptions of Poisson purchasing at the individual level and a gamma mixing of Poisson rates across the population. A test of the predictive fit of the NBD model is also derived. Using this predictive test and the proposed technique, the authors show how to diagnose some failures of the NBD assumptions. The effects of the technique on the resu/ts of conditional trend analyses are explored. The technique is illustrated using simulations and then applied to consumer panel data for seven product classes. A Predictive Test of the NBD Model that Controls for Non-stationarity The Negative Binomial Distribution (NBD) model was introduced to marketing by Ehrenberg (1959) as a way of describing the pattern of consumer purchases. Almost thirty years later, the model continues to be of interest, as is evidenced by its appearance in recent articles by Morrison and Schmittlein (1981,1988), Dunn, Reader, and Wrigley (1983) and Wagner and Taudes (1986). It has also been used as a component in composite models of brand choice and purchase timing, including those of Bass, Jeuland and Wright (1980), Zufryden (1978, 1981) and Schmittlein, Bemmaor, and Morrison (1985). Thus, perhaps because of its relative simplicity and ease of estimation, the NBD enjoys a continued presence in the marketing research literature. Goodhardt and Ehrenberg (1967) use the NBD to perform "conditional trend analysis." Here buyers are first segmented by their observed number of purchases in a predictor period; their expected purchase frequencies are then predicted for a subsequent criterion period. As discussed by Morrison and Schmittlein (1988), the NBD assumes that purchase frequencies are in part random, so these conditional predictions include a measure of regression to the mean. Conditional trend analysis thus allows a researcher to make baseline predictions for both heavy and light buyers, and these predictions are corrected for an assumed randomness in the purchase process. Deviations from these baseline predictions might then be interpreted as the results of specific marketing efforts. In this way the differential effects of a marketing activity on heavy and light buyers can be examined. To use the NBD we must make three assumptions. The first is that each individuels purchase in a Poisson fashion with unobservable rate X. The second is that the dispersion in these individual rates across the population, f(1), is accurately described by the gamma distribution; though fairly flexible, the gamma is constrained to being uni-modal. The last assumption is stationarity, namely, that each individual retains the same purchase rate in the criterion period that he or she held in the predictor period. The first two assumptions have drawn much comment and some criticism, and various gereralizations to them have been proposed. With the exception of a fine review by Monison and Schmittlein (1988), however, the stationarity assumption has received little attention in the literature. In this paper, we examine the stationarity assumption and its implications for assessing the performance of the NBD as a predictive model of consumer purchase incidence. There is good reason for doing this. Marketing activities are usually designed to accelerate consumers' purchases, that is, to induce non-stationarities. 2 These non-stationarities produce deviations between predicted and actual conditional purchase frequencies, causing the NBD predictions to fail. But any non-stationarity, not just those induced by a marketing activity, will cause the NBD predictions to fail. And, given the usual level of promette activity, non-stationarities are probably present in most data sets. Indeed Sabavala (1988) recently noted that "There is no stable period!" on which to validate NBD predictions. How, then, are we to test the NBD so that we can put some faith in its conditional predictions? Rather than search for a stable period, our approach is to control for possible non-stationarities in the data so that we can test the remaining Poisson and gamma assumptions. If the NBD performs well in this context, then we can ascribe its failure in a non-controlled context to non-stationarity. Of course, such non-stationarity may or may not be the result of a particular marketing activity. That judgment we leave to the researcher. Our procedure consists of two parts: i) We develop the sampling properties of NBD conditional predictions under conditions of stationarity. These allow us to perform a formai statistical test of the NBD predictions, as was suggested by Morrison and Schmittlein (1981). ii) We devise a data manipulation that largely corrects for the effects of non-stationarity in conditional trend analyses. This allows us to create data sets that appear to have corne from stationary markets. With non-stationarity controlled for, we can use the result from part (i) to test the remaining Poisson and gamma assumptions. But, as we will show, our technique does more than just control for non-stationarities. We can use it to identify which of the three NBD assumptions is being violated, if indeed any one of them is. Thus we can use it to make a more informed choice between the simple NBD and more complex models like the Condensed NBD of Chatfield and Goodhardt (1973). In this sense our technique builds on the analytical resuits presented by Morrison and Schmittlein (1988). The rest of this paper is organized as follows: First, we discuss more fully the NBD assumptions and their implications. Next, we present our method to control for the effects of non-stationarity. In essence, this method uses die memoryless property of the Poisson purchase assumption to average individual non-stationarities across the sample. We illustrate the method on four simulated data sets, then apply it to consumer panel data from seven product classes. We are able to show which of these data sets do, and dont, meet the NBD assumptions. Discussion and conclusions follow. 3 2.The NBD: Assumptions and Issues The requisite assomptions of the NBD model are well known, but a brief review here will enhance the reader's appreciation of the discussion to follow. Poisson Purchases For a Poisson individual with unobservable rate X, the probability of a purchase occuring within any very small interval of tirne, dt, is simply the product Idt Further, the behavior of the process on any one such interval of time is independent of that on any other, so what happens in the prior instant does not affect the present. In this sense the process is memoryless, as discussed by Meyer (1970, pp 165-66) and Heyman and Sobel (1982, p 511). We can characterize the observable results of a Poisson purchase process in three ways: (i) by the distribution of purchase frequencies for a unit time, (ii) by the density function of interpurchase times, and (iii) by the distribution of a fixed number of purchases across any given interval. The Poisson process implies certain properties for each. To begin, the distribution of observed purchase frequencies in any given unit time follows the Poisson distribution P(x; ›.) = e-1 X.x/x!, (1) where 1l is the rate of purchase and x is the observed frequency. The mean of this distribution equals X, as does the variance, so purchases are highly irregular. This irregularity is also evident in the density of interpurchase times implied by the Poisson process, which is the exponential f(t; = xe-M, (2) where t is the interpurchase time. This density is memoryless: for a given rate, the timing of future purchases is independent of those in the past. Thus it implies no purchase regularity. Also, its mode is at zero, implying that the most likely time for the next purchase, given that one has just occurred, is the following instant. Finally, because the probability of a Poisson event on any very small interval equals X.dt, the distribution of a fixed number of Poisson purchases across an observation period can be viewed as a number of iid draws from a uniform distribution. This property is discussed more fully by Parzen (1962, pp 140-41) and by Schmittlein and Morrison (1985). The major criticism of the Poisson assumption is that it implies too little regularity in purchase timing (Herniter 1971). If people consume goods in a regular fashion, then we would expect them to purchase goods in a regular fashion as well. 4 With this in mind, Chatfield and Goodhardt (1973) proposed the "condensed Poisson model," where the density of individual interpurchase times is Erlang-2, which has a mode greater than zero and implies some purchase regularity. In many situations, the condensed Poisson process would seem to be quite plausible. However, neither Chatfield and Goodhardt (1973) nor Mortier and Schmittlein (1981) found it to yield consistently better fit or predictions than the Poisson model. For more discussion on this point see Morrison and Schmittlein (1988). Gamma Heterogeneity The heterogeneity in rates across the population is assumed to be described by the gamma density fa; r a) = (1/F(r)) ar e l e**1 (3) where r and a are known as the chape and scale parameters, respectively. Because the gamma density is uni-modal, there are certain forms of heterogeneity that it will not capture very well. Accordingly, generalizations of this mixing model have been proposed. Morrison (1969) combined a gamma mixing density with a "spike" at zero to describe the presence of hard-core non-buyers in the sample. Robbins (1977) proposed an empirical Bayes estimator that allows for an arbitrary mixing of Poisson processes. A recent analysis of Navy recruiter productivity by Carroll, Lee, and Rao (1986) applies both of these generalizations. NBD Mode! For a fixed t

The high demand of seaweed for their polysaccharide namely carrageenan leads to the commercial production of carrageenophytes through mariculture. Based on literatures it is well documented that growth rate and carrageenan yield depend on environmental factors such as salinity, pH, temperatures, light intensity and water movement. In this study, growth rate and carrageenan yield of Gracilaria manilaensis, a red seaweed, was determined at different pH and salinities. G. manilaensis was cultured under laboratory conditions in a 500 mL flask at different salinities (15 psu, 20 psu and 25 psu ) and pH (7.6, 7.8, and 8.0) for 21 days. At the end of experiment, the growth rate was determined followed by carrageenan analysis. From the analysis, growth rate was highest at salinity of 15 psu and pH 7.6 with 1.3 ± 0.2 % day-1.For carrageenan analysis, the seaweed was air dried for about a week until it reached a constant weight. Farmed G. manilaensis was used as control and carrageenan yield was determined from farmed G. manilaensis. It gives yield of 50.2 ± 10.9 %. For carrageenan yield analysis, the highest value was demonstrated at salinity of 25 psu and pH 8.0 with 91.7± 14.4 %. Result shows that carrageenan yields from G. manilaensis under laboratory conditions are higher compared to farmed Gracillaria. This indicates that the quality of G. manilaensis in term of carrageenan content can be optimized under certain growth conditions. This is important as this species has the potential to be commercialized for pharmaceutical and food industries.


Background 38; Aim: Nandrolone is a testosterone derivative which increases the size of the muscle by increasing protein production. This chemical is sometimes abused by athletes. The aim of present study is to review the effect of resistance training and crocin consumption on catalase and glutathione peroxidase of heart tissue of nandrolone poisoned rats. Methods: 40 rats were selected and assigned to 8 groups including: 1; control, 2; sham, 3; nandrolone, 4; nandrolone with resistance training, 5; nandrolone with 12.5 mg/kg crocin, 6; nandrolone with 25 mg/kg crocin, 7; nandrolone with resistance training and 12.5 mg/kg crocin, and 8; nandrolone with resistance training and 25 mg/kg crocin. Groups 4, 7 and 8 performed resistance trainings for eight weeks and three sessions per week and groups of 5- 8 received daily doses of crocin. To analyze the findings of the study, one-way ANOVA and Bonferron's post hoc tests were used . Results: 25 mg/kg crocin (P=0.002), training + 12.5 mg/kg crocin (P=0.003), training + 25 mg/kg crocin (P=0.001), significantly reduce the catalase activity; training + 12.5 mg/kg crocin (P=0.001) and training + 25 mg/kg crocin (P=0.001) rather than training have more potent effect on reduction of catalase; 12.5 mg/kg crocin significantly increased glutathione peroxidase (P=0.02). Conclusion: It appears that co-administration of crocin and resistance training does not have antioxidant interactions in nandrolone poisoned rats.


We design, analyze and measure several algorithms for finding the rational zeros of univariate polynomials with integral coefficients of any size. The quadratic Newton-Hensel type algorithm behaves best in theory and practice. It has a maximum computing time of $O(n^3 L(d)^2 )$, where n is the degree and d measures the coefficient size of the given squarefree polynomial using classical arithmetic. We extend the method to Gaussian rational numbers.


The semantic forcing of marks for the Basic Paraconsistent Logic system, LBPc, is obtained from the semantic forcing of marks for the classical logic, adding a new operator called weaknegation. The inference rules for this negation indicate that the weak negation comes from the usual negation, but only in particular cases the reverse is valid. The resulting system supports weak contradictions and serves as a basis for the study of inconsistent theories but non-trivial.

This paper introduces a new remote sensing technique based on polarimetric detection principles, aimed at enhancing the discrimination of unresolved materials, Amorphous Silicon and Polysilicon. Some of the polarimetric measurements performed at different angles of incidence (angular rotations) of these materials are presented using backscattered polarimetric signals obtained with a polarimetric system (test bed). A new discrimination technique of these materials based on their angle of rotation has been presented. This technique calculates the rotation angle at which maximum discrimination between these materials is possible using a thresholding method. Based on the initial results, it can be said that maximum discrimination between the materials is possible more at off-axis angles than at the angle of incidence.


ABSTRACT In this research work, the effect of Fe additions on the phase evolution, microstructure, chemical composition, transformation behaviour and properties of Ni(50−X)Ti50FeX shape memory alloys has been investigated. The elemental Ti, Ni and Fe mixed powders are compacted at 600 MPa, followed by sintering at 1100°C for 4hr in an Ar atmosphere. Phase analysis and microstructural studies confirmed the presence of the NiTi phase besides other Ni-rich and Ti-rich phases. The 8at.-% Fe sample shows higher relative density, lower porosity, higher hardness, higher elastic modulus and higher wear resistance owing to the presence of a higher amount of secondary intermetallic phases compared to other composition samples. Interestingly, the 4at.-% Fe sample has a higher percentage of NiTi (B19') phase and shows a better shape memory effect and elastic recovery than other composition samples. FESEM morphology of worn surface explained various wear mechanisms with respect to shape memory behaviour.

This article describes a new modification of printed Yagi antennas. The presented antenna can significantly reduce a size in comparison with the well-known printed dipole Yagi antennas. There are the rules of quasi-Yagi antenna pattern's formation and impedance matching conditions are considered in this article. After calculating characteristics and sizes of the antenna, the quasi-Yagi antenna was optimized using computer simulation. Optimization of the antenna was carried out on the center frequency of 1.85 GHz. As a result, the printed quasi-Yagi antenna has much smaller dimension and weight characteristics compared to its analogs and can be used in wireless telecommunication systems.


In recent years, environmental issues such as global warming and the energy resource depletion have become serious matters. So the steelmaking industry is strongly required to develop new technologies for further energy conservation in view of energy security. A lot of energy used for industrial processes has been wasted as heat. Waste heat recovery can be one of the key technologies to meet the requirement. Thermoelectric generator (TEG) is one of the promising technologies expected to play an important role for steel plant's waste heat recovery, particularly radiant heat from steel products which had not been used yet efficiently. A 10-kW class in plant grid-connected TEG system was constructed in the continuous casting line at East Japan Works (Keihin District) of JFE Steel Corporation. The performance and durability of the TEG system have been investigated under various operating conditions. This paper will describe results of the verification tests at the continuous casting line.


This study uses 1995 1999 Contingent Workers Supplement and hospital ownership data from the American Hospital Association's Annual Surveys to how the employer sponsored insurance market responds to changes in hospital ownership. A Nested Multinomial Logit model estimates a two dimensional choice set of availability of an employer based plan and participation in that plan. The model indicates that access to a public hospital system produces a negligible effect on insurance availability and participation for all but the lowest income workers, and the data showed no appreciable difference for not-for-profit and for-profit hospitals.

A convenient synthesis of phthalides [isobenzofuran-1(3H)-ones] from o-halogenobenzyl alcohols is described. This method is then applied to the synthesis of methyl di-O-methylporphyrilate (methyl 1,3-dihydro-4,10-dimethoxy-8-methyl-3-oxoisobenzofuro[5,4-b]benzofuran-7-carboxylate)(2), a derivative of the lichen dibenzofuran porphyrilic acid (1).


Learning neural networks using only a small amount of data is an important on-going research topic with tremendous potential for applications. In this paper, we introduce a regularizer for the variational modeling of inverse problems in imaging based on normalizing flows. Our regularizer, called patchNR, involves a normalizing flow learned on patches of very few images. The subsequent reconstruction method is completely unsupervised and the same regularizer can be used for different forward operators acting on the same class of images. By investigating the distribution of patches versus those of the whole image class, we prove that our variational model is indeed a MAP approach. Our model can be generalized to conditional patchNRs, if additional supervised information is available. Numerical examples for low-dose CT, limited-angle CT and superresolution of material images demonstrate that our method provides high quality results among unsupervised methods, but requires only few data.


In the flip-chip assembly process, no-flow underfill materials have a particular advantage over traditional underfills as the application and curing of this type of underfill can be undertaken before and during the reflow process - adding high volume throughput. Adopting a no-flow underfill process may result in underfill entrapment between solder and fluid, voiding in the underfill, a possible delamination between underfill and surrounding surfaces. The magnitude of these phenomena may adversely affect the reliability of the assembly in terms of solder joint thermal fatigue. This paper presents both an experimental and mdeling analysis investigating the reliabity of a flip-chip component and how the magnitude of underfill entrapment may affect thermal-mechanical fatigue life.


We study the time development of strongly coupled ${\cal N}=4$ supersymmetric Yang Mills (SYM) theory on cosmological Friedmann-Robertson-Walker (FRW) backgrounds via the AdS/CFT correspondence. We implement the cosmological background as a boundary metric fulfilling the Friedmann equation with a four-dimensional cosmological constant and a dark radiation term. We analyze the dual bulk solution of the type IIB supergravity and find that the time-dependence of the FRW background strongly influences the dynamical properties of the SYM theory. We in particular find a phase transition between a confined and a deconfined phase. We also argue that some cosmological solutions could be related to the inflationary scenario.

It is shown that in the intermediate coupling regime, conductance and magnetization could display universal fluctuations. In particular, new anomalous Coulomb oscillations assisted by the multi-Kondo peaks are predicted theoretically.


Abstract In 2016 OECD put forward a routine problem to simulate the operation conditions in VVER-1000 reactor of Rostov NPP unit No. 2 taking into account control rod motions. The participants were encouraged to simulate the integrated process and obtain the indications of the hot leg temperature control sensors depending on control rod motions. The data from in the experiment at 75% nominal power was selected for the first test carried out in the frames of the international task. Insertion of the 10th and 9th CPS rod groups into the core without driving was carried out in the low power testing experiments at Rostov NPP unit No. 2 (May 31, 2010). The task was split into several subtasks, each with its own specifics. One of such subtasks is focused on the simulation of the standard temperature control indications at the FA outlet. The way of solving the abovementioned subtask is reflected in the present report.


In the underwater dynamic gravimetry, gravimetry system consists of strapdown gravimeter based on inertial navigation system (INS), Doppler velocity log (DVL), depth gauge (DG), and ultrashort baseline acoustic positioning system (USBL). Among them, INS provides the attitude and specific force; the velocity and depth are given by DVL and DG, respectively; the position is measured by USBL. However, USBL is challenged by the underwater extreme environment. We analyzed the underwater gravimetry errors and found that horizontal position errors have no great contribution to gravity calculation. Thus, a new method based on integrated navigation combining INS, DVL, and DG is proposed without USBL. To evaluate the availability of the new method, an underwater gravimetry experiment was constructed in 2018. Test results using the proposed method show that the internal accuracies of two measuring lines are 1.06 and 0.89 mGal, respectively, with a spatial resolution of about 250 m. Compared with the method based on integrated navigation combining INS, DVL, USBL, and DG, the new method can reach comparable accuracy and meet the requirement of seafloor resource exploration.

The present research attempted to observe the temperature and osmotic stress effects on yeast species in cheese. The Candida maltosa yeast was isolated from locally made raw cheese samples, and it was identified by its biochemical properties, followed by using the BIOLOGTM microbial identification system to confirm species level identification. The study investigate about Candida maltosa's ability to grow and develop a budding pattern under high temperatures up to 44°C and osmotic stress for 72 h. Osmotic stress tolerance was studied at 32.5°C in different concentrations of dextrose (0.04 g/l, 0.12 g/l, 0.2 g/l, 0.28 g/l, and 0.36 g/l) and sucrose (0.02 g/l, 0.06 g/l, and 0.36 g/l), respectively. Cell growth of the C. maltosa was measured by optical density at 600nm (OD600) and the enumeration of colony forming units (CFUs) on the agar plates up to 300 m. The obtained result indicated the optimal growth pattern at 32.5°C and complete growth retardation at 44°C with the high concentrations of dextrose (0.36 g/l) and sucrose (0.38 g/l). Particularly, C. maltosa budding could only survive 240 m at 37°C to 40°C and was suppressed at 44°C. The experimental findings demonstrated the stress response in yeast cells in the phenotypic level with the existing acquaintance on the osmotic stress response actions in C. maltosa.
