This paper presents advancements in electrical submersible pump (ESP) technology that were specifically designed for use in high-enthalpy geothermal wells. It discusses the unique challenges associated with geothermal operations and highlights the opportunities offered by the new ESP technology to enhance production from these wells. The paper also provides a comprehensive overview of the key components of the ESP system, including the motor, protector, pump, power cable, motor lead extension, and downhole sensors. The new ESP system demonstrates improved reliability, power density, and operational efficiency by using high-efficiency permanent magnet motors, innovative encapsulation technologies, and optimized pump designs. The paper also highlights the successful field trial of the newly developed geothermal ESP in Kizildere Field that showcased its enhanced reliability and increased production in a high-temperature environment. The findings from this trial have paved the way for the design and implementation of the new ESP system in additional high-enthalpy wells, further expanding the application of ESP technology to geothermal energy extraction. Overall, this paper underscores the transformative potential of ESP technology in enhancing the use of geothermal resources for sustainable energy production.

glucose isomerase when it was cultured in a medium containing xylan or xylan-containing materials such as wheat bran, corn cobs, or corn husks etc. This strain produced xylanase in the culture fluid, however, it was found that the main product from xylan by this xylanase was xylobiose. On the basis of this finding, the forma tion of glucose isomerase by the strain with xylobiose and D-xylose was investigated. Cultivation of Streptomyces sp. YT-No. 5 and indu ction experiments of glucose isomerase were carried out as follows: Streptomyces sp. YT-No. 5 was cultured on the reciprocal shaker in a medium containing 1g, poly peptone; 0.3g, K2HPO4; 0.1g, MgS04•E7H20 and 1g, glucose in 100 ml of distilled water for 16hr at 30•Ž. After cultivation the cells were collected by centri fugation, washed and resuspended in distilled water (cell concentration, 10•`15mg/mi as dry matter). Five milliliters of the cell suspension was added to 5ml of the induction medium containing 0.05m, phosphate buffer (pH 7), 2%, polypeptone; 0.01M, MgSO4; 0.002M, COC12 and the indicated amount of xylobiose or D-xylose in the flask of 50ml capacity, and shaked at 30•Ž on a rotary shaker (200rpm). At every two hrs, 2ml of aliquots was taken out and the activity of


We have investigated the efficacy of liposome encapsulated N-(phosphonacetyl)-L-aspartic acid (PALA) for the treatment of the C-26 murine colon tumor in Balb/c mice, and have compared it in this regard to free PALA. Healthy female Balb/c mice and C-26 tumor inoculated mice were randomized for the maximum tolerated dose (MTD) study and the in vivo therapy study, and the survival was measured after a single intraperitoneal injection of the drug. The maximum tolerated dose for intraperitoneally administered drug was found to be 750 mg/Kg for free PALA, and was greater than the maximum dose possible (150 mg/Kg) for PALA encapsulated in both DSPC and DSPG liposomes. When drug was administered one day after tumor implantation, 150 mg/Kg of PALA in DSPG liposomes increased the percentage of tumor bearing mice surviving at day 36 from 8% (buffer control) to 88%. In contrast, 150 mg/Kg free PALA increased the day 36 surviving percentage to only 25%. A 150 mg/Kg dose of PALA in DSPC liposomes increased the surviving percentage to 50%, while a 75 mg/Kg dose of PALA in sterically stabilized liposomes increased the surviving percentage to 78%. These results show that PALA in negatively charged or sterically stabilized liposomes can exhibit considerably greater potency than free PALA in C-26 tumor bearing mice.

A rapid GC-MS method is presented for the simultaneous screening and quantition of 39 different drugs in blood including eg. benzodiazepines, opiates, cannabinoids, tricyclic antidepressants. The method was developed in order to detect drugs in driving cases. The sample treatment involved liquid-liquid extraction followed by silylation as a derivatization technique. Screening and quantitation were performed by Agilent Network GC-MS 6890/5973 with HP 35% PH ME siloxane column in SIM mode. In validation tests the method showed good linearity at the relevant concentrations. The attained levels of quantition varied between 2-20000 ng/ml depending on the typical concentrations levels found in blood. Consequently the limits of quantitation were 2-2000 ng/ml. The intra-assay relative standard deviations were 2,28-22,18% and the inaccuracy 0,04-44,7% on cut-off level. Despite large variety of different kind of substances and low detection limits, the method is easy to access. The developed method is especially useful for the routine blood samples drawn from suspected drugged drivers.

Cloud computing offers ability to provide parallel and distributed simulated services remotely to the users through the internet. Services hosted within the "cloud "can potentially incur processing delay due to load sharing among other active services , and can cause active optimistic simulation protocols to perform poorly. Number of complex application runs in remote data centres, parallel processing capabilities often show a increase in utilization of CPU resources as parallelism grows, mainly because of communication and synchronization. To achieve certain level of utilization, Our proposed method partitions a node's computing capacity into the 4-tiers with low CPU priority, medium CPU priority, high CPU priority and very high CPU priority. In large datacenter, processes of a job may need to be allocated to nodes that are close to each other to minimize the communication cost. We provide scheduling algorithms for parallel jobs to make efficient use of the k-tiers VMs to improve the responsiveness of these jobs. We focus on improving resource utilization for datacenters that run parallel jobs; particularly we intend to make use of the remaining computing capacity of datacenter nodes that run parallel processes with low resource utilization to improve the performance of parallel job scheduling. The method is practical and effective for consolidating parallel workload in data centres.


Realist arguments are a combination of two discrete, though often intersecting, literatures. The first emerging from the works of classical realists such as Thucydides and Machiavelli, and the second spreading across the history of Western philosophy. One of the most significant aspects of realism is its use of historical evidence, as if one can detect a timeless wisdom of world politics centred upon the principles of realpolitik.


Activated protein C (APC) exerts its physiologic anticoagulant role by proteolytic inactivation of the blood coagulation cofactors Va and VIIIa. To identify regions on the surface of the light chain of APC that mediate anticoagulant activity, 10 synthetic peptides were prepared and tested for their ability to inhibit APC anticoagulant activity. The synthetic peptide-(142-155) inhibited APC anticoagulant activity in Xa-1-stage coagulation assays in normal and protein S-depleted plasma with 50% inhibition at 5-25 microM peptide. In a system using purified clotting factors, peptide-(142-155) inhibited APC catalyzed inactivation of factor Va in the presence or absence of phospholipids with 50% inhibition at 50 microM peptide. However, peptide-(142-155) had no effect on APC amidolytic activity or on the reaction of APC with the serpin, recombinant [Arg358]-alpha 1-antitrypsin. Moreover, peptide-(142-155) inhibited factor Xa clotting activity in normal plasma as well as in a prothrombinase assay in the presence of factor Va with 50% inhibition at 5 microM and 50 microM peptide, respectively, under the assay conditions. The peptide had no significant effect on factor Xa or thrombin amidolytic activity and no effect on the clotting of purified fibrinogen by thrombin, suggesting that it does not directly inhibit these enzymes' active sites. Peptide-(142-155) was shown to bind directly to immobilized factor Va.(ABSTRACT TRUNCATED AT 250 WORDS)


Japan A95 is a chromatin-associated protein that inter-faces the nuclear envelope (NE) and chromatin. We report an interaction between HA95 and the inner nuclear membrane protein lamina-associated polypeptide (LAP) 2 (cid:2) , and a role of this association in initiation of DNA replication. Precipitation of GST–LAP2 (cid:2) fusion proteins and overlays of immobilized HA95 indicate that a first HA95-binding region lies within amino acids 137–242 of LAP2 (cid:2) . A second domain sufficient to bind HA95 colocalizes with the lamin B–binding domain of LAP2 (cid:2) at residues 299–373. HA95–LAP2 (cid:2) interaction is not required for H formation. However, disruption of the association of HA95 with the NH 2 -terminal HA95-binding domain of LAP2 (cid:2) abolishes the initiation, but not elongation, of DNA replication in purified G1 phase nuclei incubated in S-phase extract. Inhibition of replication initiation correlates with proteasome-mediated proteolysis of Cdc6, a component of the prereplication complex. Rescue of Cdc6 degradation with proteasome inhibitors restores replication. We propose that an interaction of LAP2 (cid:2) , or LAP2 proteins, with HA95 is involved in the control of initiation of DNA


Phenylketonuria (PKU) belongs to genetically determined types of hyperphenylalaninemia (HPA). Due to all-population screening and possibilities of successful therapy it represents a model example of medical approach to hereditary metabolic disorders. The optimal metabolic compensation enables an adequate mental development without neurological damage. In contrast, insufficient metabolic compensation results in CNS damage. The early childhood is the period of highest health risk. The autohors analyze the occurrence of PKU consequences and their relation to the degree of metabolic compensation in a group of 66 patients from the Center for Long-term Observation of Patients with PKU at Children's Hospital in Kosice. No pathological symptoms were observed in the subgroup with non-PKU HPA. The ideal and medium degree of metabolic compensation was associated with a lower occurrence of PKU consequences. On the other hand, insufficient compensation was associated with a high incidence of pathological manifestations (90 % occurrence of psychopathological and 67 % occurrence of neuropathological sings).

An American historian, it might be supposed, would find the fusion of advanced technology and extraterrestrial visitors with the history of the young American republic and the deaths of the Founding Fathers a preposterous mix. Admittedly, the idea of a smart screen-wielding John Adams or Benjamin Franklin negotiating with aliens necessitates leaving aside a strict historical understanding of the eighteenth century. But, if one allows oneself the small luxury of slipping into the fantastic world Damien Lincoln Ober weaves, essential truths— and many of the darkest fears of the American experience—emerge decoupled from a static moment in the past. Doctor Benjamin Franklin's Dream America is set, at least chronologically, from 1777 through 1832. For an historian, these are important book ends: 1777 began with the second of twin victories for the Continental Army in New Jersey, peaked with an American victory at the Battle of Saratoga that induced the French to join the war against Britain, and closed with the encampment at Valley Forge; while 1832 witnessed the Nullification Crisis, Andrew Jackson's reelection, and the scuttling of the Second Bank of the United States. Such significant events are of no importance to the narrative. Instead, the dates represent the years during which all fifty-six signers of the Declaration of Independence died. Crucially, DBFDA owes its unconventional structure to the Founders' deaths: the fifty-six, two-to-six page chapters correspond to each of the deaths of the Founders. Their final minutes and hours become the vehicles that propel the narrative. The story opens with the death of John Morton, the first signer to die less than a year after signing the DOI, as Ober's America calls it. One suspects something is up when we discover our dying patriot tapping away on his laptop, a small group of other Founders by his death bed discussing the vagaries of the Cloud. Yet all else—the horses, houses, and sailing vessels; the Native Americans hiding in New York's vast forests, the muskets, and Red Coats—remains in its eighteenth-century form. In less capable hands, the mix of digital and antique would confuse, if not distract. Ober's writing somehow draws in the reader as if nothing out of the ordinary is happening. You see, Ober's America is a digitally advanced, fossil fuel deprived dystopia—one in which events online often outstrip action in "The Real," or temporal world. The Revolution is in great danger in 1777, but not from Red Coats, alone. Instead, a series of outbreaks of a disease named "The Death," which is ultimately linked to Internet usage, literally a downloadable bio-virus, wipes out two-thirds of the population in America and Europe. To complicate matters, autopsies produce stunning results: victims' bodies each contain a single large crystal tucked in among the organs and viscera of the abdominal cavity. The crystals, by the way, are possibly linked to extraterrestrials, whom Americans term "Off-Worlders," who hover in their spacecraft over major port cities a la the movie Independence Day (1996), the mere presence of the ships menacing even without overt action on the part of the Off-Worlders. Of course, Benjamin Franklin negotiates an agreement with the visitors whereby, in exchange for providing a cure for The Death (which the Off-Worlders may have caused), cleaning up the millions of corpses that littered streets and homes (and taking the crystals within their bodies with them), and bestowing upon the nation fourteen tons of solid gold bars (a gift which nearly sank the western world's financial system), the Off-Worlders were permitted to siphon every last drop of the oil, declared by Franklin as "all that filthy sludge gone forever." (Historical aside: Volume II of DBFDA should explore the rise of industrialization without the benefit of kerosene, lubricating oil, diesel, and gasoline, to say nothing of petrochemicals!) Meanwhile, the Internet has gone berserk, infected with rogue programs, worms, viruses, and avatars that collect information and continue to interact with other avatars long after the "owner" of an avatar has died. In response, the old Internet was walled off and replaced by Newnet and, later, Franklin's new Dream America. Dream America is an entirely new sort of ether world that has the propensity to absorb its users'—and everyone uses it all the time—spirit, soul, consciousness, and life essence. The leaps of fantasy are, for this historian, overshadowed by Ober's ability to weave conventional history into the narrative by highlighting the political and ideological battles of the period. It is obvious that Ober did his homework on not only the Founders' deaths, a relatively straightforward task, but also on the sociopolitical upheaval of the period. DBFDA touches upon the concerns of Founders and people with the modern


Several aspects of TNO SOC performance characteristics will be discussed, with a focus on steam electrolysis performance and lifetime behaviour during endurance tests of several thousand hours. Excellent steam electrolysis performance of the TNO SOE cells is observed at thermoneutral voltage, achieving current density values of −1.7 A/cm2 at an operating temperature of 750 °C. Lifetime assessment and material degradation of the SOC will be discussed, with a focus on the analysis of observed degradation phenomena in the oxygen electrode material. As oxygen electrode degradation can be critical for SOC performance in a stack environment, it is important to have a good understanding of the degradation processes and the ability to monitor them. At TNO, a novel approach of high-resolution 2D mapping of the lateral conductivity of the oxygen electrode has been used as an effective tool for quality control and validation of the oxygen electrode development. Additionally, the combination of 2D sheet resistance mapping, SEM-EDX and XRD techniques provides a powerful combination of tools to obtain a spatially resolved (3D) view of the localized degradation observed in the oxygen electrode after several thousand hours of steam electrolysis.


SSL/TLS certificates are used by more and more network services, but their lifespan keeps decreasing. Managing certificates on a large network is extremely time consuming, both as manpower and as complexity. This paper presents an automatic SSL/TLS certificate management system based on a single certificate manager, which makes generation and distribution of certificates efficient and traceable, while keeping the flexibility of multiple administrators for various domains. The system offers a web interface and a CLI, while keeping software dependencies at a minimum. The software is used in production on a large heterogeneous network at Carnegie Mellon University.


China has adopted free education for those major in normal education in Beijing Normal University and other five national normal universities which are administrated by the Ministry of Education. This new policy has reinvigorated higher normal education and bring normal universities with new opportunities. However, a close examination of this new policy reveals certain conflicts between policy ideals and its implementation. The article reflects upon these conflicts and puts forward some practical recommendations.


Luminosity and correlated color temperature (CCT) have gradually become two of the most important factors in the evaluation of the performance of light sources. However, although most color performance evaluation metrics are highly correlated with CCT, these metrics often do not account for light sources with different CCTs. This paper proposes the existence of a relationship between luminosity and CCT to remove the effects of CCT and to allow for a fairer judgment of light sources under the current color performance evaluation metrics. This paper utilizes the Hyper-Spectral Imaging (HSI) technique to recreate images of a standard color checker under different luminosities, CCT, and light sources. The images are then analyzed and transformed into interpolation figures and equal color difference curves. This paper utilizes statistic tools and symmetry properties to determine an exponential relationship between luminosity and CCT in red-green-blue (RGB) LED and OLED light sources. Such a relationship presents an option to remove the effects of CCT in color evaluation standards, as well as provide a guide line for adjusting visual experience solely by adjusting luminosity when creating a lighting system.


Fake-coin criminal cases occur frequently nowadays. Its affirmation and the standard of placing such a case on file are the bases of its investigation.


In recent years online education has overgrown be-cause of the many advantages it offers. During courses, different institutions collect and analyze student performance data to improve their educational experience. One of the main challenges of online education is being able to detect those students who have difficulties completing the course. This paper presents an approach to classify student success based on Random Forests and Neural Networks. One of the characteristics of Random Forests is that the algorithm selects the best feature to split the data. The selection of the most relevant features were used to train the Neural Network models.


Based on amplitude character of quantum Rabi oscillation driven by coherent field we show that there exists an upper bound to logic complexity of quantum circuit. We introduce a parameter called single-qubit logic complexity and estimate its decoherence limit in a reasonable case. The analysis show that a generally accepted constant threshold of the threshold theorem limits the logic complexity to so small a number that even a typical construction of fault-tolerant quantum Toffoli gate can hardly be implemented reliably. This result suggests that the construction of feasible fault-tolerant quantum gates is still an arduous task.

The presence of a starch splitting ferment in the blood of mammals has long been known and has been the subject of a great many experimental and clinical studies; yet its significance under normal, as well as under pathologic conditions, has remained somewhat of a mystery. This may be due partly to the lack of uniformity and relative inadequacy of the present methods for the quantitative measurement of the enzyme. In connection with other experiments on the external secretion of the pancreas, we became interested in studying blood amylase, and were impressed, as others have been, with certain practical disadvantages of, as well as theoretical objections to, such methods. METHODS Two general types of method have been employed in the measurement of blood and urinary amylase. One has been based on the disappearance of the original starch solution, as revealed by its failure to give an iodine reaction; 1 the other,


The article discusses protection of labor as the legal and social issue.

The first part of the paper defines the labor, its role and social significance both individually as well as the general public. The job is shown as a common good which requires protection of the state according to art. 24 of the Polish Constitution. The authors discuss the international regulations and constitutional obligations in this regard. The final part of the paper contains authors conclusions about the causes of lack of adequate protection for labor as a social value and the conditions for the protection and development of the value of the labor market.

Prohibited Substances and Methods is not only to prevent "cheating" in sport, i.e. unfair performance enhancement by the use of drugs, but also to protect the health of athletes, as well as the spirit of sport, as broad as the latter can be. Therefore, the avoidance of "cheating" should be of equal importance as the protection of health of athletes and the protection of the spirit of sport. According to the World Anti-Doping Code [11] any substance or method compromising two out of the above three criteria should be included in the List of Prohibited Substances and Methods.


The two-potential formula of scattering theory is used to determine the low energy scattering by long range potentials having the asymptotic form r-3. An interaction of this form occurs between two identical neutral atoms which are excited to different degrees. The author calculates tan delta 0 up to and including the k4 term and, for L>0, we calculate tan delta L up to and including the K2L+1 term.


Novel core-shell hollow mesoporous Prussian blue @ Mn-containing Prussian blue analogue (HMPB@MnPBA) nanoparticles, designated as HMPB-Mn) as an intelligent theranostic nanoagent, are successfully constructed by coating a similarly crystal-structured MnPBA onto HMPB. This can be used as a pH-responsive T1 -weighted magnetic resonance imaging contrast agent with ultrahigh longitudinal relaxivity (r1 = 7.43 m m(-1) s(-1) ), and achieves the real-time monitoring of drug release.


Background Survival of acutely unwell patients depends on prompt recognition and resuscitation.1 Time pressures, workload and the importance of managing such patients is a significant source of stress for junior doctors, making them feel underprepared for their role and contributing to error.2 Summary of work Our study aims to investigate the impact of stress management strategies on junior doctors undertaking simulated medical emergencies. We aim to explore how these interventions affect doctors' self-reported and observed stress, and establish the influence on speed and accuracy of diagnosis. Doctors (n=18) in first and second years of core medical training will be randomised into two groups. Group A will receive specific teaching on cognitive control techniques and controlled breathing prior to high fidelity simulations, whilst participants in Group B will receive a standard simulation course which does not include any specific focus on stress management techniques. Time to various transition points and diagnosis will be recorded for each participant. Stress will be assessed using heart rate variability, participant self-rating questionnaires and stress levels rated by an observer. Summary of results This is an ongoing study, full results will be available for presentation at the conference. Preliminary data indicates that stress management techniques may be effective in reducing observed stress and increasing heart rate variability during medical emergencies, but have less effect on self-reported stress levels. Discussion and conclusion Data collection is currently ongoing. Statistical analysis of the data will help us to establish whether cognitive control and controlled breathing techniques improve junior doctors' coping mechanisms during medical emergencies.

As the usability and value of personal information increase, the importance of privacy protection has increased. In Korea, the scope of the use of pseudonymized personal information has increased because of revisions to the law. In the past, security technologies were used to safely store and manage personal information, but now, security technologies focused on usability are needed to safely use personal information. In this paper, we look at issues related to the de-identification and re-identification of personal information. Moreover, we examine the standards and techniques related to the de-identification of personal information.


Introduction: Acute encephalitis syndrome (AES) is a constellation of clinical signs and or symptoms i.e. acute fever with acute change in mental status. AES may be present as encephalitis, meningoencephalitis or meningitis. It can be associated with severe complication, including impaired consciousness, seizure, limb paresis or death. Materials and Methods: Study consisted of retrospective analysis of hospital records of children up to 16 years of age admitted with diagnosis of AES in the department of Paediatrics Dhulikhel Hospital, Kathmandu University Teaching Hospital, Dhulikhel Kavre from January 2010 to December 2011. Results: During the two years (January 2010 to December 2011), 47 patients of AES were admitted. Among the admitted cases there were 34 male and 13 female patients. Meningitis cases were 29, encephalitis cases were 14 and 4 meningoencephalitis cases. Among the meningitis cases, viral meningitis accounted for 12, bacterial meningitis accounted for 15 and 1 tubercular meningitis.One was eosinopilic meningitis in which the causative organism was found to be fasciolosis by ELISA. Viral encephalitis was found to be the most common cause of encephalitis. Sensorineural hearing loss was seen in 3 cases, subdural effusion in 1 and hydrocephalus in 1. One patient had intracranial hemorrhage with hemiparesis as a complication of eosinophilic meningitis. Conclusion: Acute encephalitis syndrome is one of the most common causes of PICU admission in Dhulikhel hospital. Bacterial meningitis was common among the acute encephalitis syndrome followed by viral meningitis. One case of eosinophilic meningitis with intracranical hemorrhage and hemiparesis was found. Sensorineural hearing loss was found to be commonest complication. DOI: http://dx.doi.org/10.3126/jnps.v32i3.6683 J. Nepal Paediatr. SocVol.32(3) 2012 201-205

membrane. In experimentingon a dog, Reed used "Sodium amytal" anresthesia and exposed the stomach by a mid-line incision. An incision was made'iil the stomachwall, and into the organ was inserteda rubber balloon filled with water without tension. The balloon. was attached to a rubber tube and the wound in the stomach was firmly suturedaround the tube. Another rubber hul loou, simila-rly filled and attachedtoa rubber tube, was placed in the abdominalcavity uunong the loops of intestines. The abdominal wound was dosed and the tubes were attached to mercury manometers. "'hen pressurewas applied to the dog's abdomen the pressurein the two manometers-was equal in every instance. Blows on the abdomen directly over the.stomach caused an equal rise in both manometers,but no movements of the mercury could be observedthat would indicatethat the hlow over the stomachcauseda sufficient increasein the peristalsisof the stomach to .lend to a rise in the intragastric' pressure. Reed, applying these observationsto the ruptureof a gastriculcer, points out that if' it took an appreciable time for the intraabdominalpressureoutside the stomach and the intragastric pressure to become equalized, ruptureof an ulcer might occurduring this interval. At the New South Wales Branch discussion one of the speakerssaid that when pressurewas made on the abdomen,the stomachhad to "take up" the pressure, -and once the pressurewas relieved, the stomach had to relieve its pressurealso. Reed recorded the movements of the mercury on a revolving drum, and he found that the cxtragastric increaseand the Intragastric-increasein pressure occurredsimul taneously, Reed also dealt with certain conditions in which it is known that hollow viscera'do rupture. Those interested in this question must consult Reed's article for detailsof his observations. Our purpose is to raise the question'of rupture of gastric ulcer. Admittedly it is not always possible to refer to the humanbody resultsobtainedin experimentson animals,yet even the most scepticalwill be forced to admit that Reed's results are most suggestive. Both Reed and Corlette believe that the laws of physics are applicable to living tissue. They have the weight of evidence on their side. We must conclude that if physical laws hold good outside the body, they hold good inside the body. IIi view of the experimental results of Reed, the onus of proof restson thosewho would exceptthe body from the application of such laws as Boyle's andthat of Pascal.


The improvement of agricultural green total factor productivity (AGTFP) is crucial to achieve sustainable agricultural development. By matching China's provincial digital financial inclusion index and agricultural production data from 2011 to 2020, and on the basis of using the DEA–Malmquist productivity index to measure AGTFP, the fixed effect model and Mesomeric effect model are used to empirically test the impact and mechanism of digital financial development on China's AGTFP. Our research found that from 2011 to 2020, China experienced consistent improvement in AGTFP, which was largely attributed to advancements in technology. Interestingly, the AGTFP in non-major grain-producing areas surpassed that in major grain producing areas. Additionally, digital finance has proven to be an effective tool in boosting China's AGTFP, the coverage subdimension, the depth of use subdimension and the digitization subdimension all significantly promote the AGTFP. Digital finance can significantly promote the efficiency and progress of agricultural green technology, which shows that digital finance promotes AGTFP in a "dual wheel" driven manner. However, the impact of digital finance on agricultural green technology efficiency and progress is more pronounced in major grain-producing areas than in non-major areas. The impact mechanism demonstrates that digital finance has the potential to stimulate AGTFP in two key ways. First, it can improve the mismatch of agricultural production resources; second, it can promote agricultural technology innovation. Therefore, it is necessary to further promote the rapid development of digital finance, optimize the rational allocation of financial resources, and formulate tailored digital finance development strategies to promote green development of agriculture.


Abstract : A free boundary problem is a (steady-state) boundary value problem involving differential equations on domains parts of whose boundaries, the free boundaries, are unknown and must be determined as part of the solution. A trial free-boundary method is a numerical method for solving free boundary problems in which the boundary is found by guessing the position of the boundary, solving a boundary-value problem in the resulting region, and using this solution to find a new guess for the position of the boundary, the procedure being repeated until the desired accuracy has been attained. This report gives a comprehensive survey of trial free-boundary methods. (Author)


Manganese (Mn2+) oxidation in contact filter layer under neutral pH condition is the biological oxidation, the balance and stability of biome with Mn2+ removal organism as center in filter layer is the basis of Mn2+ removal activity. The bio-filter can not only result in the simultaneous removal of Fe2+ and Mn2+, but also effectively capture the fine particles that have been oxidated to Fe3+ before entering the filter layer. Based on the mechanism of biological Mn2+ fixation and removal, simple process of weak aeration and primary filtering has been developed for biological Fe2+ and Mn2+ removal, the related design and operating parameters have been determined, and instruction has been given to the design and operation of water treatment plant with Fe2+ and Mn2+removal in Shenyang Development Area. Since the plant was put into operation for one more year, it has achieved good effluent quality with trace amount of total iron and Mn2+ 0.05 mg/L.


Engineering educators might be interested in innovative strategies to support student learning. We propose a creative design approach to support engineering students' learning: visual notetaking. In this work, we designed, offered, and researched a 10-week seminar on visual notetaking for thirteen undergraduate engineering students at the University of Washington. During the seminar we engaged in weekly conversations on visual notetaking topics such as layout, color, and text hierarchy. Afterward, we interviewed nine of the thirteen enrolled students and analyzed their artifacts generated from the seminar. We report our findings in two parts: first, we describe the iterative process of designing our visual notetaking seminar; second, we present vignettes and artifacts to highlight student experiences' in the seminar. One of our contributions to engineering education includes sharing our detailed curriculum design such that educators can promote visual notetaking practices in their contexts. Second, we encourage the engineering education community to consider how we can create opportunities for students to design their own active learning experience within traditional engineering classroom settings.


The full story of Sir Ronald Ross' ever memorable discovery with regard to the transmission of malaria is ?old in his Memoirs, a book which every research worker in medicine should read. The Memoirs. however, are now being supplemented by publication of (he original letters and documents concerned, by the Ross Institute. As only one of the above four publications is marked with a price, we take it that these publications are chiefly for private circulation. ?>ut every large medical library in India should certainly possess a copy of each. (/) The first contains a letter dated the 22nd August 1897 from Ross to Manson reporting his discovery of malarial oocysts, with a photograph of his drawing of them from the original letter. A second letter, dated 'ho 31st August, 1897, records the observation of oocysts of later development, and Ross' firm (and correct.) conviction that he was working on the right, lines. An extract from Dr. G. C. Low's presidential address to the Royal Society of Tropical Medicine and Hygiene 011 the 18th October, 1929, summarising Ross' work, completes (lie brochure.

This article describes efforts to improve an 11.6-mile stretch of U.S. 285 that winds through the Colorado Rocky Mountain foothills southwest of Denver. Concerns were first raised in the 1970s about the need for a better roadway, but work did not begin until 1991. It was completed in five phases over some 13 years, and finally finished in 2003. The project involved moving more than 500,000 cubic yards of material and replacing an accident-prone intersection with a 230-foot steel-girder flyover bridge with the tightest curve radius of any such bridge in Colorado. Each phase of the project offered similar challenges, which are described here. Traffic volumes tripled from 10,000 a day in 1991 to nearly 30,000 in 2003.


Motivated by the recent establishment of a connection between central star binarity and extreme abundance discrepancies in planetary nebulae, we have carried out a spectroscopic survey targeting planetary nebula with binary central stars and previously unmeasured recombination line abundances. We have discovered seven new extreme abundance discrepancies, confirming that binarity is key to understanding the abundance discrepancy problem. Analysis of all 15 objects with a binary central star and a measured abundance discrepancy suggests a cut-off period of about 1.15 days, below which extreme abundance discrepancies are found.


Ethical decision-making, and the choice of whether or not to be truthful, is an important part of everybody's life. For nurses, decisions such as these are made every day and affect not just themselves, but also the lives of others. This article will examine the ethics of truth-telling from the point of view of a theatre nurse dealing with a seriously ill patient.


The doctoral research process is the entry path for the academic profession. Traditionally it is explained by reference to another professional entry path, the industrial apprenticeship. Revisiting a paper and discussion originally held at the Marketing Education Group conference in 1991, we explore the implications and limitations of this metaphorical model, suggest alternatives and consider the interaction between student characteristics and supervisory approach. Through this process we offer marketing academics a vast range of unflattering metaphors to employ in describing themselves, their students, their supervisors and their colleagues.

The paper contains a survey of the problems commonly encountered by anyone attempting to accurately determine or specify the speed of fast photodetectors, in the bandwidth range: hundreds of MHz - tens of GHz. Two techniques are presented: one determining the minimum duration of the optical pulses which can be "seen" accurately enough, and the other determining the electrical (power) spectrum of the photodetector, leading to bandwidth determination. Experimental determination of the bandwidth for two fast photodiodes is presented, using the latter technique.


This paper suggests a methodology to realize fractional order impedance using feedback control of a motor, which can be called fractional impedance control. First, a novel discretization method of a fractional order integrator is proposed based on the coefficient fitting by particle swarm optimization. Based on this fractional order integrator, fractional order impedance control is realized using feedback control design. The characteristics of fractional impedance are analyzed by simulations, and the algorithm is implemented in a motor and the characteristics are made clear by experiments.


The importance of phenolics in disease resiatance has been recognized by many investigators. Both qualitative and quantitative changes in phenolic compounds are usually associated with host parasite interactions (SADASIVAN 1965,

Shades of Laura: Vladimir Nabokov's last novel "The Original of Laura", edited by Yuri Leving, Montreal, McGill-Queen's University Press, 2013, xii + 307 pp., $29.95 (pbk), ISBN 978-0-773-54264-8This collection is not the first academic response to the posthumous publication of Vladimir Nabokov's unfinished manuscript but it is remarkable in several ways. First, four years' distance allows the contributors to compare their perspectives on the text's significance before and after its publication. Secondly, the book offers an unusually versatile approach to the posthumous publication of a canonical author's manuscript; the diverse topics will attract a range of specialists from the publishing sector to literary theory and translation. And finally, the book itself, a peculiar arrangement of conventional and not so academic genres, recalls the electronic hypertext the contributors mention so often given the rich connections between Nabokov's work and the digital humanities.The book is divided into six parts, including an introduction by the editor and an afterword by Brian Boyd. The main body of Shades of Laura traces the lifecycle of these "fragments from a novel", as many contributors call them, in four parts titled "A Picture in Fragments", "Reading is Fun: Approaches to Analysis", "Critical Reception", and "A Toolbox". Each covers a separate aspect of Laura's emergence - composition and publication, scholarly feedback, reception in media and press, and translation into five languages. It is not necessary to have read the novel in order to appreciate the carefully orchestrated discussion in Shades of Laura. The first part, "A Picture in Fragments", offers a detailed chronology of Laura's composition and publication, reconstructed from Nabokov's diary and his and Vera's correspondence with publishers and friends. It reads as a detective story and dynamically reproduces Nabokov's struggle to finish the novel despite sickness, a heavy workload, and time itself. This part is followed by a round table devoted largely to the controversy around Dmitri Nabokov's dilemma over whether to disobey his father's last will, the publicity campaign surrounding the publication, and the marketing strategies of US and Russian publishers. The discussion is guided by well-chosen questions from Yuri Leving which often spur an exchange of opinions among such prominent Nabokovians as Galya Diment, Leland de la Durantaye, Michael Juliar, Eric Naiman, and Olga Voronina.The second part is a compilation of several academic articles dealing with Laura's fragmentary nature and significance for the contemporary view on Nabokov's oeuvre as a whole. Some, such as Gennady Barabtarlo in his article "Terminating the Phrase", make assumptions about the novel's missing sections and plot potential. Relying on intense engagement with the text made possible through the labour of translation, Barabtarlo attempts to tie up the "loose ends" (68) of Nabokov's plot, lines that seem "in want of development, branching out, grafting, characterization, coordination with others, etc" (70). His analysis allows him to suggest that "the material in hand" comprises only one-third of the whole novel, but features a "provisional closing". Others attempt to fit Laura into a theoretical frame: thus, Michael Rodgers in his article "The Original of Laura and Nietzsche: A Zarathustran Tool?" finds parallels between the appropriation of death through writing and the Zarathustran "inversion of morality" (124). …

Proceeding from wave equations, the paper strictly deduced the dispersion relation equation of Love-type channel waves in Standard Linear Solid model. The equation is a complex one with its real part signifying the dispersion characteristics of the channel wave while the imaginary part, the attenuation characteristics. In calculating the attenuation value, the author has set up a mathematical model of a horizontal symmetric sequence (a three layer sequence of rock-coal-rock), given out some physical parameters, and adopted the dichotomy method that is more often used inroot resolving of an equation. The calculation indicates that the influence of nonelastic absorption on the attenuation of the propagation of channel wave varies with thefrequency. In the frequency band of the Airy phase, the attenuation increases steeplike, which is unfavorable for the channel wave seismic prospecting. The study ofchannel wave attenuation has provided a theoretical basis for the compensation of attenuation.


Confucius is a famous educator in Chinese history. In his almost 50 years'teaching career, Confucius audaciously set forth the proposition "Anyone's nature is similar while education makes it different", showed out the signboard of "Everyone should be educated equally" and initiated Confucian school. He thought the purpose of education was to cultivate senior administrative talents "junzi" and took "the six classics" as the teaching contents. Moreover, he recruited students in a large scale and cultivated "three thousand pupils" by inspiring, guiding and teaching them according to their aptitudes. Confucius was insatiable in learning and tireless in teaching all his life. Indeed he deserves to be the Model Teacher of Myriads of Ages. All his life is just the best generalization of teacher spirit that has lasted for several thousand years in China. The spirit should be carried forward.

A thermo-mechanical model for ceramic materials subjected to thermal shock is presented in this paper.The model was based on the thermo-mechanical coupling principle,and the statistical method was used to consider the heterogeneity of ceramics at the mesoscopic level,which is different from the previous models based on the so-called continuous damage mechanics.The failure process of plane ceramics subjected to thermal shock was investigated to validate this model and also to reveal the failure mechanism of ceramic materials under the thermal condition.The results show that the cracks are initiated ruleless on the surface where it is subjected to thermal shock at the beginning of the thermal shock.However,with the further thermal conduction some cracks gradually grow in the inner normal direction of the surface while the propagation of other cracks is restrained.The results well agree with the experimental data.The proposed approach provides a new method to model the failure process of ceramic materials subjected to thermal shock.


Generally, there are Chua's Circuit, Lorenz Circuit and Duffing circuit in the chaos circuit. Among these chaos circuits, Chua's circuit is well known to make the electronic parts easily. Chua's circuit is the constitute of the linearelements. These are constitute of Resistor component(R), inductor component(L), capacitor(C), and nonlinear element which is constitute of nonlinear resistor. However, L element have a difficult problem to implement real hardware by using commercial parts. Due to this, it has a saturation characteristic. In this paper, we analyzed the simplified Chua's circuit which is replace L to C by PSPICE program. Because L element has a difficult problem to make a real hardware, L has a saturation characteristic and we also confirm this analysis as the result.


Microglial activation is a dynamic process, central to neuroinflammation, which can have beneficial or pathogenic effects to human health. Mitochondria are key players in neuroinflammatory and neurodegenerative processes, common to most brain diseases. To the best of our knowledge on the role of mitochondria in the modulation of neuroinflammation, we focused on the mitochondrial uncoupling protein‐2 (UCP2), known to control mitochondrial functions and to be implicated in a variety of physiological and pathological processes. In primary microglial cultures, the M1 stimulus lipopolysaccharide induced an early and transitory decrease in UCP2 levels. The initial UCP2 down‐regulation was paralleled by mitochondrial inner membrane potential (mMP) depolarization and increased mitochondrial reactive oxygen species production. The key role of UCP2 in controlling mMP and reactive oxygen species production was confirmed by both pharmacological inhibition and down‐regulation by RNA interference. Additionally, UCP2‐silenced microglia stimulated with lipopolysaccharide showed an enhanced inflammatory response, characterized by a greater production of nitric oxide and interleukin‐6. UCP2 was differently regulated by M2 stimuli, as indicated by its persistent up‐regulation by interleukin‐4. In UCP2‐silenced microglia, interleukin‐4 failed to induce M2 genes (mannose receptor 1 and interleukin‐10) and to reduce M1 genes (inducible nitric oxide synthase and tumour necrosis factor‐α). Our findings indicate that UCP2 is central to the process of microglial activation, with opposite regulation of M1 and M2 responses, and point to UCP2 manipulation as a potential strategy for redirecting microglial response towards protective phenotypes in several brain diseases where neuroinflammation is recognized to contribute to neurodegeneration.


The conjugation length-dependent nonlinear optical properties of fluorenone-based linear conjugated oligomers have been investigated by experimental and theoretical methods. Infrared spectra and the steady-state absorption spectra show that the increase of conjugated unit could enhance the stretching vibration peaks of C=C and lead to a red-shift of the absorption peaks. Meanwhile, the two-photon fluorescence (TPF) intensity is gradually enhanced with the increase of excitation energy, and the TPF efficiency is obviously higher after the introduction of fluorene-ethylene units. The sum-over-states approach was used to model the two-photon absorption (TPA) cross-sections of oligomers, and the theoretical values agree well with the experimental data obtained from the femtosecond open-aperture z-scan technique. The results exhibit that the extension of conjugated system indeed plays a role in the improvement of TPA behavior of oligomers.


Dr. Zhang: Our work looks at the diversity of CRISPR systems. CRISPR is not a single system; there are many different types. This new system is something where a transposable element called Tn7 has, over the course of evolution, co-opted a CRISPR so that it can use the RNA targeting mechanism of CRISPR to spread itself to viruses or plasmids. By studying the molecular mechanism of this, we realized that it's a potentially programmable way to be able to introduce DNA into the genome. One of the major hurdles of gene editing is we can cut DNA, but introducing DNA into the genome in a precise way has been challenging. Using these transposable elements that are RNA-guided, there's the potential to develop a new genome-editing tool.


Tailoring radiative properties such as spectral control of thermal emission is beneficial in many applications such as space cooling and energy harvesting. The effect of magnetic polaritons (MPs) on spectral modulation has been analyzed previously and shown to exhibit omnidirectional behaviors when magnetic polaritons are excited in metallic grating structures with a dielectric spacer on a metallic film. The present work provides an experimental demonstration of coherent thermal emission from such a microstructure in the infrared region at both room and elevated temperatures. Samples with different patterns are fabricated to study the geometric effect on the MPs. The emittance at elevated temperatures is directly measured using a home-built emissometer, while the room-temperature emittance is indirectly obtained from the reflectance measurements. The rigorous coupled-wave analysis and the LC model are employed to elucidate the mechanisms, by incorporating the Drude model with a temperature-dependent scattering rate.Copyright © 2012 by ASME


Abstract Analysis of a supercell storm that did not produce a tornado near Hays, Kansas, is presented. A well-defined midlevel mesocyclone was apparent throughout most of the storm's life cycle. Numerous shallow circulations were observed along the rear-flank gust front during the data collection period. Six of these circulations strengthened into intense low-level mesocyclones. Each of these mesocyclones failed to produce a tornado. The strongest low-level mesocyclone, referred to as vortex #4, underwent a life cycle that was consistent with other tornadic mesocyclones documented in the literature. These results illustrate that the presence of a long-lived mesocyclone at low levels is not sufficient for tornadogenesis to occur. The kinematic structure of the low-level mesocyclone that did not produce a tornado is compared with a tornadic mesocyclone from another storm in order to understand the characteristic differences between these circulations. The results lead to the conclusion that the presence of ...

A study was conducted in the haor areas of Bangladesh to assess the land utilization status, delineate the productivity and profitability of growing modern rice, evaluate the existing cropping patterns and assess the prospect of possible cropping patterns. Both primary and secondary data were used in the study. Applying the conventional descriptive statistics, the study revealed that, there are about 1.26 million hectares of cultivated lands in seven haor districts, of which 66% falls under haor area. In Kishoregonj and Hobigonj, nearly 94 and 87% areas were devoted to MV Boro rice production. Both BRRI dhan 28 and 29 were being the widely adopted rice varieties. On an average, about 33% of the haor areas were under mechanized irrigation, but in Kishoregonj, the coverage of mechanized irrigation was 87% that helped increasing cropping intensity. The cost of production for MV Boro was almost double than that of LV rice. The yield of MV Boro was 79% higher than that of LVs and the return from MVs was 82% higher. Rabi-Fallow-T. Aman, Vegetable-Aus-T. Aman and Rabi-B.Aman patterns were the potential cropping patterns in some selected areas and this could increase both cropping intensity and productivity in those areas. According to the farmers' assessment, lack of flood control dam and lack of short duration varieties etc. are the major hindrance to the adoption of potential cropping patterns. Construction of community harvest and threshing facilities and flood control devices could be the important public interventions for enhanced agricultural productivity in the haor areas.

Single Truck Identification Data is an electronic data collection system for every truck operating at a designated port to support activities at the port. Single Truck Identification Data will later become the single identity of each truck, with an electronic-based system connected to the port management IT system containing a database covering the technical feasibility of trucks and their drivers, including data on truck vehicle police numbers and transportation company owners. However, there are still many trucks and companies that have not registered their companies and have not pocketed a Single Truck Identification Data card; therefore, there are obstacles faced by business actors so that until now they have not registered their companies. The lack of preparation of trucking companies in using the system and the lack of knowledge about the Single Truck Identification Data system are obstacles to implementing the system. The factor of implementing the system is to facilitate the flow of goods at the port. Efforts can be made to reduce existing obstacles by providing socialization and technical guidance to truck drivers and operators, as well as improving services for trucking companies to register their fleets.

In this paper two collocation methods, the direct linear interpolation collocation method and the direct high order interpolation collocation method, are proposed to solve the second kind of Volterra integral equations with weakly singular highly oscillatory Fourier or Airy kernels. The purpose is to solve the equations by Kummer hypergeometric and Gamma functions for solving the modified moments, where the modified moments are transformed from the integration interval [0,x] to the interval [−1,1]. The detailed collocation procedure is provided and the effectiveness of these algorithms are proved by convergence analysis and numerical experiments. Further, numerical examples are used to prove that the direct linear interpolation collocation method and the direct high order interpolation collocation method are also effective for solving highly oscillatory equations without weakly singularities.


This paper focuses on statistical analyses in scenarios where some samples from the matched pairs design are missing, resulting in partially matched samples. Motivated by the idea of meta‐analysis, we recast the partially matched samples as coming from two experimental designs and propose a simple yet robust approach based on the weighted Z‐test to integrate the p‐values computed from these two designs. We show that the proposed approach achieves better operating characteristics in simulations and a case study, compared with existing methods for partially matched samples.

Ringing plants of the determinate tomato (Lycopersicon esculentum Mill cv. Summit) with copper wire when fruit had set on 3, 7 and 12 clusters increased early and total yield. Earlier ringing did not produce such increments. Ringing had no effect on fruit size and percent marketable yields.


Although it has been previously observed that organizational identification consists of multiple dimensions, the relative effect of each dimension on performance outcome, for example, job satisfaction, remains largely overlooked. Thus, the present study attempted how each dimension of organizational identification affects job satisfaction, which in turns affects customer orientation in the casino context. A total of 260 employees working in two casino companies in Seoul were selected as a study sample. The results of this study confirmed that three aspects(i.e., affective, cognitive, and evaluative identification) of organizational identification could be distinguished as separate factors in a principal analysis, and all three factors had an signigicant effect on job satisfaction. Out of three factors, affective identification had the most strong relationship with job satisfaction. In addition, job satisfaction affected customer orientation positively and significantly. Furthermore, implications were discussed and a few things in the conclusion based on this research findings were suggested.


We discuss the results of the radio studies of the X-ray binaries with relativistic jets. We carried out a multi-frequency (1-30 GHz) daily monitoring of the radio flux variability of the microquasars SS433, GRS1915+105, and Cyg X-3 with the RATAN-600 radio telescope during the recent sets from 1 November 2006 to 31 August 2008. From December 2005 radio emission of Cyg X-3 after four years relatively quiescent levels (100-200 mJy) dropped down to ∼20 mJy, and then we detected a lot of bright radio flaring events (1-20 Jy) followed the very variable (from 0 to 0.5 crabs) 15-50 keV X-ray emission, which was monitored in the Swift/BAT ASM program. Again from December 2007 to March 2008 we have daily measured almost quiescent fluxes from Cyg X-3 but in April 2008 a bright radio flare with clear synchrotron self-absorption was detected. We detected several bright short-term flares from GRS 1915+105 which could be associated with active soft X-ray events. In intense measurements of SS433 fluxes (often mutually with X-ray and optical observations) we detected massive ejections during powerful flares. We discuss the various spectral and temporal characteristics of the light curves from the microquasars. Monitoring of the flaring radio emission is a good tracer of jet activity X-ray binaries.

The effect of the antimalarial chloroquine {7-chloro-4-[4-(diethylamino)-1-methylbutylamino]quinoline} on the oxidation of 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonate)(abts) promoted by ferriprotoporphyrin IX [(3,7,12,17-tetramethyl-8,13-divinylporphyrin-2,18-dipropanoato)iron(III)] and H2O2 was studied. Under the conditions [abts][H2O2][catalyst], the kinetic results showed a first-order dependence on both the peroxide (up to 8 × 10–3 mol dm–3) and the catalyst concentration (up to 4 × 10–6 mol dm–3), although a saturation effect was observed at higher concentrations. The values of the apparent second-order rate constants in the absence and presence of chlorcquine were (1.71 ± 0.05)× 105 and (1.23 ± 0.04)× 105 dm6 mol–2 s–1 at pH 6.86, 303.1 ± 0.2 K, and I= 0.10 mol dm–3 NaCl. Therefore, the antimalarial inhibits the peroxidase activity by about 28% due the formation of a catalytically inactive complex with the haem. A first-order dependence on the concentration of abts was also verified, followed by a zero-order dependence at concentrations higher than 5 × 10–3 mol dm–3. Some EPR spin-trapping experiments, and comparative studies in the presence of bromide ions, provided evidence for the participation of analogues of the horseradish peroxidase compounds I and II rather than hydroxyl radicals, in the peroxidase activity of the haem. The results are discussed in the context of the antimalarial activity of chloroquine.

Prescribed burning can be a viable tool for managing forest ecosystems. However, smoke from prescribed fires, which often occur in the wildland-urban interface (WUI), can linger in an area for relatively long periods of time and have an adverse effect on human health. Smoke from low-intensity prescribed fires can also reduce visibility over roads and highways in the vicinity of these fires, producing hazardous conditions for transportation. Improved tools that quantitatively predict the potential impacts of smoke are necessary in order to maximize the benefits of prescribed fires and balance the conflicting needs of ecological fire use and effective smoke management. This three-year (2009-2012) study, funded by the Joint Fire Science Program and the National Fire Plan, is focused on the evaluation and potential adaptation of three stateof-the-art fine-scale atmospheric dispersion modeling systems for predicting short-range, near-source smoke transport and diffusion from low intensity fires within and above forest vegetation layers. These modeling systems include the Weather Research and Forecasting (WRF) – FLEXPART system, the Regional Atmospheric Modeling System (RAMS) – Forest Large Eddy Simulation (RAFLES) system, and the Atmosphere to Computational Fluid Dynamics (A2C) system. Smoke concentration, meteorological, and fuel measurements via surface and tower-based instrumentation within and in the vicinity of prescribed burn units in the New Jersey Pine Barrens will be used to validate the modeling systems. Through this study, we seek to (1) improve our understanding of the effects of different forest canopies on particulate matter and water vapor transport and diffusion within and above those canopies, (2) examine how those effects could be included in operational smoke prediction systems, (3) determine the uncertainties and limitations of current models in predicting smoke dispersion from low intensity fires, and (4) develop new observational data sets for effective validation of smoke dispersion models. Project Goal and Hypotheses Study Goal Adapt three existing numerical models for predicting short-range smoke transport and diffusion from low intensity fires and evaluate their performance using observational data from prescribed burn experiments. Study Hypotheses •Land-surface characteristics, such as terrain and forest vegetation, and near-surface atmospheric processes induced by variations in terrain and vegetation can have significant impacts on smoke transport and diffusion from low-intensity fires. •Improved understanding of these impacts will lead to better predictions of smoke transport and dispersion over areas of complex terrain and forest vegetation.

Because of high energy-consumption and complexity of central air-conditioning system,the traditional control technique can not save energy efficiently,then intelligent control technique is brought in.The application of the intelligent control technique in central air-conditioning system for energy efficiency was discussed by depending on utilizing the principle of fuzzy control and neural network control in the theory of intelligent control,and the application of fuzzy control in the constant air volume air-conditioning system and the variable air volume air-conditioning system were analyzed in detail.


The main object of the presented research is to apply thermal analysis in order to investigate microstructure of hardened cement paste. The test is conducted by means of differential scanning calorimetry on samples stored in various relative humidity levels as well as the fully saturated ones. The obtained results describe water solidification beginning at several different temperatures, which implies complex nature of cement paste microstructure. The recorded thermograms consist of two main peaks, which clearly indicate the division into capillary and gel pores. Additionally, the thermodynamic properties of actual pore solution confined in cement matrix are investigated. The obtained results indicate ions present in the liquid strongly affects its phase transition temperature as well as amount of ice formed during such the phase change.


In this work, the processes of applying protective conversion coatings based on rare-earth metal compounds for passivation of the surface of a Zn-Ni alloy were investigated. The mechanism of formation, composition and corrosion characteristics of passivating films were investigated. It is shown that the investigated chromate-free coatings are comparable to rainbow chromate layers in corrosion resistance and protective ability. It was found that these coatings withstand thermal shock without deterioration of functional characteristics. It has been revealed that cerium-, lanthanum-containing coatings, like chromate coatings, have the ability to self-heal.


A 4-year-old female spayed Golden Retriever was evaluated after generalized seizures for 2 days and a 1-month history of decreased appetite, conjunctivitis in the left eye (OS), and pyoderma. Therapy with oral cephalexin (25.6mg/kg PO q12h), neopolydex ophthalmic solution (OS q6h), and oral phenobarbital (1.6mg/ kg PO q12h) did not improve clinical signs. Physical examination revealed multifocal nodular skin lesions, granulomatous fundic lesions in both eyes (OU), and uveitis OS. Neurologic examination abnormalities included an absent menace response and direct pupillary light reflex OS, delayed conscious proprioception in all limbs and generalized ataxia. Neuroanatomic localization was forebrain. CBC and serum biochemistry profile results were within reference intervals. On thoracic radiographs, a bilateral interstitial pulmonary pattern was present in the caudal dorsal lung fields with a round, soft tissue opacity (2.5 2 cm) in the left caudal lung. Magnetic resonance imaging (MRI) of the brain was performed with a 1.0 T magnet. Images included T2weighted (T2W), fluid-attenuated inversion recovery (FLAIR), and T1-weighted (T1W) images before and after intravenous contrast administration (0.1mmol/kg gadodiamide). Multifocal intraand extra-axial lesions causing a mild left midline shift were identified in the right cerebrum, thalamus, and midbrain). Lesions were also present in the left ocular posterior chamber and temporalis muscles adjacent to affected brain region. Brain lesions were hypointense to grey matter on T1W images and mildly hyperintense with marked perilesional edema on T2W and FLAIR images. After contrast administration, there was enhancement of lesions and meninges (Fig 1). Radiological diagnosis was multifocal brain disease with secondary meningitis and left ocular granuloma or retinal hemorrhage. Cisternal cerebrospinal fluid (CSF) analysis showed 15 white blood cells/mL (reference range, 5), 2 red blood cells/mL, and 25.9mg/dL protein (reference range, 25). The differential cell count was 30% neutrophils, 60% lymphocytes, and 10%macrophages. CSF immunoflourescence antibody titer (IFAT) for Neospora caninum was 10 (reference, 10 positive). Microscopic examination of an aspirate of the pulmonary mass showed pyogranulomatous inflammation and Blastomyces dermatitidis organisms. Disseminated blastomycosis was presumptively diagnosed and the dog was treated with fluconazole (5mg/kg PO q12h); phenobarbital (2.5mg/kg PO q12h), cephalexin (20mg/ kg PO q12h), and neopolydex (OU q8h) were continued. The dog represented for examination because of acute obtundation 2 weeks later. Inflammation secondary to death of Blastomyces organisms in the central nervous system (CNS) was suspected. After therapy of dexamethasone sodium phosphate (0.07mg/kg IV once) and prednisone (0.25mg/kg PO q12h), the dog's clinical signs rapidly improved. Clindamycin (10mg/kg PO q12h) was added based on a N. caninum serum titer of 400 (reference, 100 indicates exposure). One month later, neurologic examination was normal except for absent menace response and direct pupillary light reflex OS. On MRI examination there was resolution of the muscle granuloma, persistence of intracranial granulomas and parenchymal edema, and lateral ventriculomegaly. Cisternal CSF analysis was within reference intervals. Prednisone therapy was tapered and discontinued. The dog had recurrence of ataxia and conscious proprioception deficits 10weeks later. OnMRI, there was resolution of 2 forebrain granulomas; however, a new granuloma From the Department ofMedical Sciences (Lipitz, Rylander, Foy) and the Department of Surgical Sciences (Forrest), School of Veterinary Medicine, University of Wisconsin—Madison, Madison, WI.

The paper reviews animal inhalation and human epidemiological studies with talc. The human studies show that talc can induce COPD and lung fibrosis in workers exposed to high levels to talcum powder. No evidence for lung cancer due to talc inhalation has been found in long-term prospective follow-up studies. Background Current information on the health effects and toxicology of talc suggests that this may lead to a specific target organ toxicity arising from repeated exposure (STOT-RE) classification. Objective To provide an assessment of the currently available inhalation toxicity data on talc and to put these data in the perspective of other poorly soluble low-toxicity particles. Methods A database of 177 articles was gathered from different sources. Results Relevant animal data sets were subjected to a quality review, and epidemiological studies on talc and lung effects published since 2016 were reviewed. Conclusions Of nine original inhalation studies reviewed, only one study using rats and mice met the criteria that are needed to include for a reliable evaluation for STOT-RE. Together with the pulmonary effects observed in exposed talc miners, a STOT-RE 1 classification is warranted.

We discuss the environment of local hard X-ray selected active galaxies, with reference to two independent group catalogues. We find that the fraction of these AGN in S0 host galaxies decreases strongly as a function of galaxy group size (halo mass) – which contrasts with the increasing fraction of galaxies of S0 type in denser environments. However, there is no evidence for an environmental dependence of AGN in spiral galaxies. Because most AGN are found in spiral galaxies, this dilutes the signature of environmental dependence for the population as a whole. We argue that the differing results for AGN in disc-dominated and bulge-dominated galaxies are related to the source of the gas fuelling the AGN, and so may also impact the luminosity function, duty cycle and obscuration. We find that there is a significant difference in the luminosity function for AGN in spiral and S0 galaxies, and tentative evidence for some difference in the fraction of obscured AGN.


Batch and repeat batch fermentation were performed to evaluate the potential of date syrup and immobilized cells technique for the economical production of α-amylase. The enzyme production by immobilized cells was greater than that of freely suspended cells. Khlas date syrup gave the highest enzyme yield (142.7 Uml-1) using the immobilized technique after 48 h of fermentation. The highest α-amylase production was obtained in a culture grown in a 2% tricalcium phosphate treated medium. The enzyme production was proportional to the amount of date syrup up to 1.0% sugar. Tween 80 was more effective in enhancing cell membrane permeability, and thus increasing enzyme secretion. A 1.4 fold increase in enzyme production was achieved using an optimized medium in a fermenter. The culture activity under repeated batch cultivation remained stable up to the third cycle, and retained about 85% of its initial efficiency during the first five batches when each cycle continued for 48 h. The stimulated activity and the thermo stability were observed in the presence of 10 mM Ca2+. The results show that date syrup is a promising economic carbohydrate source and cell immobilization is an excellent alternative method for enhanced α-amylase production.

Constrained sequences find applications in communication, magnetic recording, and biology. In this paper, we restrict our attention to the so-called (d, k) constrained binary sequences in which any run of zeros must be of length at least d and at most k, where 0lesd<k. In some applications one needs to know the number of occurrences of a given pattern w in such sequences, for which we coin the term constrained pattern matching. For a given word w or a set of words W, we estimate the (conditional) probability of the number of occurrences of w in a (d, k) sequence generated by a memoryless source. As a by-product, we enumerate asymptotically the number of (d, k) sequences with exactly r occurrences of a given word w, and compute Shannon entropy of (d, k) sequences with a given number of occurrences of w. Throughout this paper we use techniques of analytic information theory such as combinatorial calculus, generating functions, and complex asymptotics.


Although renal cell carcinoma (RCC) is believed to have a strong hereditary component, there is a paucity of published guidelines for genetic risk assessment. A panel of experts was convened to gauge current opinions.


Eclipta alba is well known herbal plant for its vast range of pharmaceutically important properties. Some of its major activities are antimytotoxic, antimicrobial, antihepatotoxic, antioxidant, antihyperglycemic, rejuveniser and antivenom action. The present study reveals the presence of secondary metabolites responsible for imparting pharmacological properties in different parts like apical tissue, meristematic cells, whole plant, Callus, Seedlings, Mature seeds, immature seeds and dries seeds obtained via plant tissue culture technique. The results shows the absence of Alkaloids in tissue cultures plants which has been normally reported to be present in huge amounts in naturally occurring plants in aqueous extracts but other metabolites viz., Flavonoids, Tannins and phenolic groups reported earlier to be occurring in Eclipta alba and its parts were found to be present in aqueous extracts of tissue cultured plant.


: Introduction: In this study, we investigated the effect of intravenous ketamine administration on acute abdominal pain in lead poisoning patients. Methods: In this cross sectional study, we evaluated 20 patients with opium abuse with acute abdominal pain due to lead poisoning. With cardiac monitoring, 0.25 mg/kg ketamine (maximum dose was considered as 20 milligrams) was administered during 30 to 60 seconds. To control ketamine complications such as psychological irritability 0.03 mg/kg midazolam (2 milligrams was considered as maximum dose) was injected slowly during one or two minutes. Patients were observed in the ED for the next 6 hours. Pain score was assessed with VAS method, serially. Pain was measured before ketamine administration, every one hour for the next two hours and every two hours for four hours. Results: In this study 20 patients were enrolled with mean age of 37.2 ± 4.2 years (range from 30 to 44 yrs.). Repeated measurement test shows significant reduce in pain score after ketamine administration (P=0.001). Five patients report no pain 4 hours after ketamine injection, and 3 of them left the hospital with personal consent before the end of the study. From 17 remaining patients, 13 ones (76.4%) had no pain, and mean VAS score in other 4 patients was less than 2 after4 6 hours. Conclusion: our results show that low dose ketamine administration can reduce abdominal pain related to lead poisoning in opium abusers.


Much of our understanding of gender perception in voice and speech is based on sustained vowels or single words, which eliminates temporal, prosodic, and articulatory cues available in more natural, connected speech. Further, while many studies have examined acoustic and sociolinguistic differences between male and female voices, the relationship between talker speaking style and perception of gender has not yet been explored. Clear speech, adopted by talkers who perceive some barrier to effective communication, is one such speaking style change. The present study examines the relationship between clear speech and talker gender perception. Clear and conversational neutral sentences produced by all 41 talkers from the Ferguson Clear Speech Database (Ferguson, 2004) were presented to young listeners with normal hearing. They rated the gender of the talker using a visual analog scale with endpoints labeled masculine and feminine, chosen to capture small within-category changes in perceived gender. Acoustic a...

A battle is underway in Massachusetts. The players are as diverse as small-town New England and downtown Boston. The central issues is the topic of gay foster parenting. One possible outcome: The state of Massachusetts, most liberal of the northeastern democratic strongholds, could become known as a major stronghold for gay political power. Control (CDC). The paper, delivered at a large Public Health Service w orkshop in B ethesda, Maryland, represents a first at tempt to re-interpret antibody test results, and to begin to understand what the test can tell about actual presence of HTLV, the virus commonly suspected to cause AIDS. Researchers, led by James Allen of the CDC's AIDS ac tivities section, found positive virus tests in about 60*Vo of cases where a person's anti body test readings were above .7, a figure which indicates the test's level of reactivity. A source close to the health service has said there has been discussion among public health officials to attempt to apply this possible new interpretation of antibody results to screen " certain types of employees" such as health care workers. Initial reaction to the new data has been cautious. Jeff Levy, Political Director for the advocacy group National Gay Task Force, said, " I don't think there is enough scientificdata to justify broadening the use of the test for anything other than that for which it is currently licensed.''

The purpose of this study is to determine the rate of short-term central line-associated bloodstream infections (CLABSI) related to port placement in patients who received prophylactic intravenous antibiotics compared with those who did not receive prophylactic antibiotics. A retrospective review of 545 consecutive patients who underwent implantable port placement at Mayo Clinic, Rochester, Minnesota, from May 2020 to June 2021 was conducted. A total of 270 patients underwent port placement with prophylactic antibiotics administration. A total of 275 patients underwent port placement without the administration of antibiotics. The rate of short-term or 30-day CLABSI in both groups was reviewed. Indications for port placement included vascular access for chemotherapy and need for long-term vascular access for intravenous hydration, intravenous immunoglobulin infusion, electroconvulsive therapy, and photophoresis. Short-term infections occurred in a total of 3 of 545 patients (0.55%). Rate of short-term infection in patients who had port placement without prophylactic antibiotics was 2 of 275 (0.72%). Rate of short-term infection in patients who underwent port placement with prophylactic antibiotics was 1 of 270 (0.37). All 3 patients presented with bacteremia and were treated with port explantation and intravenous antibiotics. Overall, 30-day CLABSI in 545 patients who underwent port placement was 0.55%. There was no significant difference in the rate of short-term infections in the group who received prophylactic antibiotics (0.37%) compared with patients who did not receive any preprocedural antibiotics (0.72%).

The conventional direction of arrival (DOA) estimation methods are performed with multiple receiving channels. In this paper, a changeling DOA estimation problem is addressed in a different scenario with only one full-functional receiving channel. A new unmanned aerial vehicle (UAV) swarm system using multiple lifted reconfigurable intelligent surface (RIS) is proposed for the DOA estimation. The UAV movement degrades the DOA estimation performance significantly, and the existing atomic norm minimization (ANM) methods cannot be used in the scenario with array perturbation. Specifically, considering the position perturbation of UAVs, a new atomic norm-based DOA estimation method is proposed, where an atomic norm is defined with the parameter of the position perturbation. Then, a customized semi-definite programming (SDP) method is derived to solve the atomic norm-based method, where different from the traditional SDP method, an additional transforming matrix is formulated. Moreover, a gradient descent method is applied to refine the estimated DOA and the position perturbation further. Simulation results show that the proposed method achieves much better DOA estimation performance in the RIS-aided UAV swarm system with only one receiving channel than various benchmark schemes.
