    2008-06-01

    This paper focuses on the relations between a liberal group of sex reformers, consisting of writers and literary critics, and physicians from the Polish Eugenics Society in interwar Poland. It illustrates the paradoxes of the mutual co-operation between these two groups during the 1930s and analyses the reason why compulsory sterilisation was rejected by politicians. From the early 1930s two movements began to forge an alliance in Poland: the sexual reform movement which advocated freedom of the individual, and eugenics, which called for limiting the freedom of the individual for the collective good. This paper draws attention to several issues which emerged as part of this collaboration: population politics, the relationship between reformers, eugenicists and state institutions, and the question of how both movements--eugenics and sexual reform--perceived the question of sexuality, birth control and abortion. It will also focus on those aspects of their thinking that led to mutual co-operation.

    Full Text Available Joko Widodo (Jokowi is a leader that is widely expected to transform Indonesia into a better country. Hopes and wishes were rising when he was elected as the president of Indonesia. This paper will describe various innovations undertaken before and after his presidential inauguration as well as the assorted innovations made in reforming the administration of his cabinet. As the president of Indonesia, Joko Widodo is required to realize the aspirations of the people in freeing the government from corruption, collusion, and nepotism. The management of ministerial and non-ministerial institutions becomes the very first crucial issue undertaken by Joko Widodo. This led to a polemic in regards to reducing or increasing the number of institutions, as the Jokowi administration actually increased the amount. In Susilo Bambang Yudhoyono's administration, several policies were made systematically and based on legislations that had been approved by the lagislature. Joko Widodo's administration in more partial in nature. The administrative reform program that is highly anticipated is the continuation of the Public Service Act. This law is a step forward from the administrative reform program that aims at the creation of good governance. Changes is career path, salary system, pension and benefits for civil servants, performance-based staffing are various efforts of sustainability carried out by Joko Widodo's administration.

    2011-01-01

    This article addresses the potential for food movements to bring about substantive changes to the current global food system. After describing the current corporate food regime, we apply Karl Polanyi's 'double-movement' thesis on capitalism to explain the regime's trends of neoliberalism and reform. Using the global food crisis as a point of departure, we introduce a comparative analytical framework for different political and social trends within the corporate food regime and global food movements, characterizing them as 'Neoliberal', 'Reformist', 'Progressive', and 'Radical', respectively, and describe each trend based on its discourse, model, and key actors, approach to the food crisis, and key documents. After a discussion of class, political permeability, and tensions within the food movements, we suggest that the current food crisis offers opportunities for strategic alliances between Progressive and Radical trends within the food movement. We conclude that while the food crisis has brought a retrenchment of neoliberalization and weak calls for reform, the worldwide growth of food movements directly and indirectly challenge the legitimacy and hegemony of the corporate food regime. Regime change will require sustained pressure from a strong global food movement, built on durable alliances between Progressive and Radical trends.

    2014-11-01

    In 2006, the Constitutional Court of Colombia issued Decision C-355/2006, which liberalized the country's abortion law. The reform was groundbreaking in its argumentation, being one of the first judicial decisions in the world to uphold abortion rights on equality grounds, and the first by a constitutional court to rule on the constitutionality of abortion within a human rights framework. It was also the first of a series of reforms that would liberalize the abortion regulation in four other Latin American countries. The Colombian case is also notable for the process of strategic litigation carried out by feminist organizations after the Court's decision, in order to ensure its implementation and counter the opposition from conservative actors working in State institutions, as well as for the active role played by the Court in that process. Based on fieldwork carried out in Colombia in 2013, this article analyzes the process of progressive implementation and reactionary backlash after Decision C-355/2006, with an emphasis on strategic litigation by the feminist movement and subsequent decisions by the Constitutional Court, which consolidated its jurisprudence in the field of abortion rights. It highlights the role of both feminists and of conservative activists within State institutions as opposing social movements, and the dynamics of political and legal mobilization and counter-mobilization in that process.

  11. In the arc of history: AIHA and the movement to reform the Toxic Substances Control Act.

    Wilson, Michael P

    2012-01-01

    Dr. Michael P. Wilson of UC Berkeley delivered his keynote address before the general assembly of the American Industrial Hygiene Conference and Exhibition (AIHce) in Portland, Oregon, in May 2011. Here, Dr. Wilson again discusses the political and economic drivers of occupational disease in the United States and proposes a role for AIHA in helping to highlight and resolve them. He proposes that until these underlying drivers are acknowledged and ameliorated, the toll of occupational disease will persist, despite the hard work of industrial hygienists in the workplace. Among these drivers, Dr. Wilson points to the decline of labor rights and unionization; economic inequality; economic insecurity; political resistance to public health protections for workers, notably the OSHA and NIOSH programs; and weaknesses in the Federal Toxic Substances Control Act of 1976 (TSCA). Of these, Dr. Wilson calls on the AIHA to participate in the historic effort to rewrite TSCA. He points to weaknesses in TSCA that have produced a chemicals market dominated by the function, price, and performance of chemicals, with little attention given to their health and environmental effects. Under these conditions, he argues, hazardous chemicals have remained economically competitive, and innovation in inherently safer chemicals-in green chemistry-has been held back by a lack of market transparency and public accountability in the industry. TSCA reform has the potential to shift the market toward green chemistry, with long-term implications for occupational disease prevention, industrial investment, and renewed energy in the industrial hygiene profession. Dr. Wilson proposes that, like previous legislative changes in the United States, TSCA reform is likely to occur in response to myriad social pressures, which include the emergence of the European Union's REACH regulation; recent chemicals policy actions in 18 U.S. states; growing support from downstream businesses; increasing public awareness

  14. Prussian phenomenon and its historical distortion

    Oleg Y. Plenkov

    2016-03-01

    Full Text Available The article deals with the phenomenon of Prussia. Once, Prussia had been the largest continental Protestant state in Europe. The main issue of this phenomenon is that upon the tragic events of the World War II Prussian history and heritage had been considerably distorted, in order to compensate somehow for the dreadful casualties suffered by the victorious powers. The common European misconception implied that Prussia had been the bulwark of militarism, and therefore had to bear all the responsibility for the atrocities of war. Unfortunately, the majority of modern German historians share such misinterpretation of Prussian heritage in order to please false political correctness, perhaps, as an act of contrition for National Socialism and its crimes. However, the Prussian tradition and history go far beyond this militarism, and this article explains what ways. The authors believe that there should not be any prejudices and biases, that any subject should be examined sine ira et studio. Moreover, given that it is possible to characterize the Great French Revolution as a juristic one, and the Great October revolution – as a social one, the Prussian revolution “from above”, led by the first representatives of the Hohenzollern family, may be well considered as a pedagogical revolution. This revolution did bring definitely positive changes; they are surveyed in the article. The French Revolution has not eliminated the covetousness of the bourgeoisie after 1789; despotism of the authorities and people’s passiveness similarly have remained unaltered in Russia after 1917. On the contrary, Federal Republic of Germany of nowadays, distinctive for its law, order and effective responsible government is unthinkable without Prussian heritage.

    During the mid 19th century, herbal remedies were the platform for a major health reform movement in America known as the Botanical Medical Movement (BMM). A number of histories have been written on the BMM from the perspectives of physicians and pharmacists. This article describes the history of nurse-herbalism during the period and the impact that Shaker nurses, in particular, had on the BMM. The article traces the history and findings of a triangulated case study. Shaker nurses used herbs extensively in their caring and curing practices. They applied the botanical remedies recommended by BMM leaders. The nurses were also expert herbal medicine makers who used their own remedies in patient care. The Shaker infirmary was the nurses' behind-the-scenes research and development laboratory for the Shaker herbal cottage industry, which ultimately developed into an international, entrepreneurial endeavor. The Shaker infirmary was the nurses' organized proving ground for the implementation of the botanical health reforms of the mid 19th century. The nurse-herbalists' contribution to the promotion and production of herbal remedies had a significant impact on the success of botanical health reform in America.

    Full Text Available Otpor is discussed in the text as a complex and contradictory new type of social movement, whose members attempted to contribute to the tradition of enlightened reform of social and political life in Serbia, simultaneously in a highly pragmatic and in a creative, possibly even irresponsible manner. After the introduction, analyzed are popular and media narratives on the characteristics of the movement, dilemmas concerning the founding of the movement and meaning of its key symbols, and the Faustian question of goals and consequences of foreign, in particular American influences. Following is a discussion of strategic (non-violent revolution, calculated victimization and tactical (black campaigns, get-out-the-vote campaign roles of Otpor in the coordinated project of ousting Milosevic. Otpor’s role is then re-interpreted in the frame of the ‘electoral revolution’, developed by Valerie Bunce, Sharon Wolchik and Michael McFoul. An assessment of the transformation of Otpor from an active social movement into an exportable blueprint for non-violent political revolutions is offered in lieu of a conclusion.

    Full Text Available The kinetics of reaction between ferrocyanide and ferric ions under acidic conditions was studied at fixed ionic strength (0.1 M and (25 plus or minus 0.1 oC by using the stopped flow technique, under limiting conditions of [ferrocyanide] and with other reactants in excess. The reaction had first-order dependence on ferrocyanide, Fe(III and H+ ion concentrations and had negative salt effect. On the basis of the experimental findings, a plausible mechanism for the formation of soluble form of Prussian blue (KFe{Fe(CN6}x H2O and rate law are proposed. The activation parameters for the title reaction are estimated. A relatively low energy of activation (23 kJ mol-1 and high negative entropy of activation (-231 J K-1 mol-1 agree well with the proposed mechanism and configuration of complex ion leading to the formation of insoluble Prussian blue, Fe4{Fe(CN6}3 y H2O.

    Highly ordered Prussian blue nanowires with diameter of about 50 nm and length up to 4 {mu}m have been fabricated by an electrodepositing technology with two-step anodizing anodic aluminum oxide films. The Moessbauer spectra taken between 15 and 300 K indicate that the hyperfine parameters decrease as the temperature increases. The temperature dependence of the quadrupole splitting, the isomer shift and the spectra area are discussed. A decrease of Debye temperature for Prussian blue nanowires was found with respect to that of Prussian blue bulk.

  20. Prussian Blue Mg-Li Hybrid Batteries.

    Sun, Xiaoqi; Duffort, Victor; Nazar, Linda F

    2016-08-01

    The major advantage of Mg batteries relies on their promise of employing an Mg metal negative electrode, which offers much higher energy density compared to graphitic carbon. However, the strong coulombic interaction of Mg 2+ ions with anions leads to their sluggish diffusion in the solid state, which along with a high desolvation energy, hinders the development of positive electrode materials. To circumvent this limitation, Mg metal negative electrodes can be used in hybrid systems by coupling an Li + insertion cathode through a dual salt electrolyte. Two "high voltage" Prussian blue analogues (average 2.3 V vs Mg/Mg 2+ ; 3.0 V vs Li/Li + ) are investigated as cathode materials and the influence of structural water is shown. Their electrochemical profiles, presenting two voltage plateaus, are explained based on the two unique Fe bonding environments. Structural water has a beneficial impact on the cell voltage. Capacities of 125 mAh g -1 are obtained at a current density of 10 mA g -1 (≈C/10), while stable performance up to 300 cycles is demonstrated at 200 mA g -1 (≈2C). The hybrid cell design is a step toward building a safe and high density energy storage system.

    Full Text Available This research of the reform movements performed during the eraof one of the important rulers of XVIII. Century, Sultan I. Mahmud who ruled for 24 years between 1730 and 1754, basically aims to shed lighton an important stage in the modernization of a society. According tothis, the Ottoman Empire who dominated Europe kept its traditionalstructure until the XVIII. Century and did not feel the need to change.However, when the European nations that developed in economic,political, cultural and technical fields began to win battles against theOttomans, the state began to question the situation it was in. Theunderstanding of accepting the superiority of the west which startedespecially with the Tulip Era was continued during the reign of Sultan I.Mahmud and western reforms were made particularly in the militaryfield. Thanks to these reforms that Sultan I. Mahmud continued duringhis 24 year reign, the state recovered significantly and recordedimportant military victories during his era. Again during the rule ofSultan I. Mahmud, with his special emphasis on the reconstruction ofthe city, Istanbul flourished with the architectural activities conductedduring his time. For all these reasons, in order to understand the era ofSultan I. Mahmud which marked a period in the Ottoman history,knowing the military and political events of this time is not enough. Thereform and transformation movements of the era have to be known aswell. This study has been prepared along these goals and objectives. Inthe study, focus has been on the reasons and general characteristics ofthe reforms. The basic idea was to identify the effects of thesemovements on the Ottoman State and their imprint on the nextreformists.

    We developed a spongiform adsorbent that contains Prussian blue, which showed a high capacity for eliminating cesium. An in situ synthesizing approach was used to synthesize Prussian blue inside diatomite cavities. Highly dispersed carbon nanotubes (CNTs) were used to form CNT networks that coated the diatomite to seal in the Prussian blue particles. These ternary (CNT/diatomite/Prussian-blue) composites were mixed with polyurethane (PU) prepolymers to produce a quaternary (PU/CNT/diatomite/Prussian-blue), spongiform adsorbent with an in situ foaming procedure. Prussian blue was permanently immobilized in the cell walls of the spongiform matrix and preferentially adsorbed cesium with a theoretical capacity of 167 mg/g cesium. Cesium was absorbed primarily by an ion-exchange mechanism, and the absorption was accomplished by self-uptake of radioactive water by the quaternary spongiform adsorbent.

    Fe nanoparticles are prepared using a unique polyol process and modified with prussian blue (PB) at various concentrations. The presence of PB in the Fe nanoparticles are confirmed from thermal, Fourier transform infrared spectroscopy and electron microscopic analyses. The prussian blue existed on ;the surface of the nanoparticles when the concentration is 200 μM and in excess with 1000 μM. ;Fe nanoparticles are reduced in size using Pt as nucleating agent and modified with the optimum concentration of PB. The saturation magnetization decreases with the concentration of PB whereas the coercivity is influenced by the size of the Fe nanoparticles. The presence of oxide layer in Fe nanoparticles helps in the surface modification with PB. The Fe nanoparticles of particle size 53 nm modified with 200 μM of PB showed a saturation magnetization of 110 emu/g. The magnetic properties suggest that the PB modified Fe nanoparticles are better candidates for detoxification applications. - Highlights: • Fe nanoparticles surface modified with prussian blue (PB) were synthesized. • Optimum PB concentration on size reduced Fe showed better magnetic properties. • Coercivity decreased with increasing concentration of PB. • Fe-PB nanoparticles could be used for detoxification applications

    The present qualitative study examined 69 published first-person accounts written by adults diagnosed with schizophrenia from 1979-2010 within the historical context of the four major mental health movements in the United States. Content analysis techniques were used to identify major topics and overarching content categories in the first-person accounts written over the 30-year period. The frequency of topics in each content category was examined as a function of the decade and corresponding mental health movement in which accounts were published. Five overarching content categories emerged reflecting authors' conceptualizations of schizophrenia, their experiences with psychiatric hospitalization, medications, coping with social stigma, and achieving and maintaining valued social roles. Two summary categories emerged reflecting authors explicit views about what helped and what did not help in their experience of living with schizophrenia. With the exception of social stigma, frequency of topics within content categories did not change as a function of decade and corresponding mental health movement. Despite changes in mental health policies, treatment, and systems of care, the overall lack of significant differences in the content of first-person accounts across the 30-year period suggests an enduring nature to the experiences of individuals coping with schizophrenia. Implications of present findings for research and practice are discussed. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

    The pigment Prussian blue is studied in heritage science because of its capricious fading behavior under light exposure. We show here that XANES can be used to study the photosensitivity of Prussian blue heritage materials despite X-ray radiation damage. We used an original approach based on X-ray photochemistry to investigate in depth the redox process of Prussian blue when it is associated with a cellulosic substrate, as in cyanotypes and watercolors. By modifying cation and proton contents of the paper substrate, we could tune both rate and extent of Prussian blue reduction. These results demonstrate that the photoreduction and fading of Prussian blue is principally mediated by the substrate and its interaction with the oxygen of the environment. (paper)

    A new approach for the synthesis of Co-Fe Prussian blue nanoparticles with controlled size has been developed in the present work. Mixture of formamide and water was used as a reaction medium for the chemical synthesis of the nanoparticles at room temperature. It has been found that the size of nanoparticles can be controlled by varying the volume ratios between formamide and water. Powder X-ray diffraction, transmission electron microscopy, diffuse reflectance UV-vis absorption spectra, and nitrogen adsorption/desorption isotherms were employed to characterize the products. The optical properties of the nanoparticles depending on particle size were observed

    Full Text Available 開放原始碼運動為軟體產業開創新的創作模式,在開放原始碼模式下的軟體持續增加,累積的成果有目共睹。但開放原始碼日益普及的背後並非沒有任何隱憂,其中智慧財產權方面的法律議題正關係著開放原始碼未來的發展。從開放原始碼相關的風險及觀察近年來智慧財產權制度的演變,有識之士指出未來軟體專利可能成為開放原始碼模式最大的挑戰,而值得加以研究。本文從探討過去各方對專利制度批評與建議的過程中,受開放原始碼模式的啟發而提出創設「公益專利」的想法,希望藉由運作機制的勾勒及相關利弊的初步分析,能為開放原始碼軟體營造一個更健全的制度環境,同時也 有機會為專利制度的改革提供一個新的思考面向。 The open source movement presents the world a new software development model. Its continuing success can be attested by the exponential growth of software projects under its wings. Pitfalls and challenges loom ahead, however. Intellectual property-related legal issues, in particular, deserve our special attention for their disrupting potential. Among various risks associated with opensource movement, the threat posed by software patents stands out and echoes the concerns by many open source pundits. After reviewing other proposed solutions so far, the author would like advance a new one—the “public patent” mechanism inspired by the movement itself, in the hope to strengthen the longterm viability of the open source movement, and add more fuel to the big debate of patent system reform.

    Since the accident at the Fukushima Daiichi power plant, Prussian blue (PB) has attracted increasing attention as a material for use in decontaminating the environment. We have focused the fundamental mechanism of specific Cs{sup +} adsorption into PB in order to develop high-performance PB-based Cs{sup +} adsorbents. The ability of PB to adsorb Cs varies considerably according to its origin such as what synthesis method was used, and under what conditions the PB was prepared. It has been commonly accepted that the exclusive abilities of PB to adsorb hydrated Cs{sup +} ions are caused by regular lattice spaces surrounded by cyanido-bridged metals. Cs{sup +} ions are trapped by simple physical adsorption in the regular lattice spaces of PB. Cs{sup +} ions are exclusively trapped by chemical adsorption via the hydrophilic lattice defect sites with proton-exchange from the coordination water. Prussian blue are believed to hold great promise for the clean-up of {sup 1}3{sup 7C}s contaminated water around nuclear facilities and/or after nuclear accidents.

However, before the specter of such accidents arose, Prussian blue was known only as an investigational agent for accidental thallium and cesium poisoning. The purpose of this review is to update the state of the art concerning use of Prussian blue as an effective and safe drug against possible bioterrorism attacks and to disseminate medical information in order to contribute to the production of Prussian blue as a biodefense drug.Methods: We compiled articles from a systematic review conducted from January 1, 1960 to March 30, 2011. The electronic databases consulted were Medline, PubMed, the Cochrane Library, and Scopus.Results: Prussian blue is effective and safe for use against radioactive intoxications involving cesium-137 and thallium. The US Food and Drug Administration has approved Prussian blue as a drug, but there is only one manufacturer providing Prussian blue to the US. Based on the evidence, Prussian blue is effective for use against radioactive intoxications involving cesium-137 and thallium, but additional clinical research on and production of Prussian blue are needed.Keywords: Prussian blue, radioactive cesium, thallium, intoxication, biodefense drug

    2012-09-01

    Full Text Available Ashik Seyrani lived between the years1800 and 1866. He was originally from Develi, Kayseri. He saw three thrones in this whole life. These are; III. Selim, II.Mahmut and Abdulmecit. His teenage and adulthood ages were in last two ones. Seyrani, expressed the emotions of the society against the innovation and westernization movements which were developed in II.Mahmut era and formalized with political reforms in Abdulmecit era. Moreover, he didn’t hesitate to depict faults and irregularities that he saw in the society without any fear from the sultan. Seyrani is considerably successful in the literary genre which is called “irony” in the classical literature and “satire” in the folk literature. This is somewhat related to his nature and character. Having come to Istanbul to pursue his profession, Seyrani, like his contemporaries, had a yearning for joining the poet-singers of the court. But, his desire did not come true. That was most probably the reason why he severely satirized the court officials, particularly the grand viziers. Another reason why Seyrani had such a firm stand against the court was the disbandment of the Janissaries. Like the other Bektashi poets, Seyrani who had a tendency towards Bektashism could not accept the disbandment of the Janissaries, and therefore took a negative stand against the court. Social and economic life of the nineteenth century is likely to be seen in the poems of Seyrani. The situation of the country after the Reform movements, extravagant spendings of the court, people’s failure in keeping up with the newnesses, Sultans’ personally adopting a Western way of living, and corruption of the judiciary due to judge’s involvement in bribery were particularly satirized in the poems of Seyrani. In this study, Reform movements and how these movements reflected on the society will be put into words with reference to poems of Seyrani and the era will be evaluated. Âşık Seyrani, 1800-1866 y

    A 6-wk study was conducted using immature (4.7 mo), young adult (2.4 y), and aged (13.5 y) male beagles to determine the modifying effect of age on the effectiveness of Prussian Blue decorporation therapy for the removal of injected 137 Cs. Whole-body clearance rates for injected 137 Cs decreased with increasing age in the dogs. Treatment with Prussian Blue changed the ratio of fecal to urinary 137 Cs excretion from 0.8 in untreated dogs to 2.2 in treated animals. The 137 Cs concentrations in tissues of untreated and Prussian Blue-treated dogs at the end of the 6-wk study were similar, with the greatest concentrations in the skeletal muscle tissue, spleen, and kidneys. There was a lower concentration of 137 Cs in the livers of the treated dogs. The reductions in the average total whole-body doses resulting from Prussian Blue treatment during the course of this study were 51% in the immature, 31% in the young adult, and 38% in the aged dogs. Because of the differences in the intake of Prussian Blue by the dogs in the different groups relative to their body weight, it is unclear as to the relative effectiveness of Prussian Blue in dogs of different ages. 33 refs., 1 fig., 5 tabs

    Carmen Diana Deere

    2004-04-01

    Full Text Available Este artigo examina a evolução da reivindicação dos direitos da mulher à terra na reforma agrária brasileira sob o prisma dos três principais movimentos sociais rurais: o Movimento dos Trabalhadores Rurais Sem Terra (MST, os sindicatos rurais e o movimento autônomo de mulheres rurais. O mérito maior por levantar a questão dos direitos da mulher à terra é das mulheres dentro dos sindicatos rurais. Os direitos formais das mulheres à terra foram conseguidos na reforma constitucional de 1988, e em grande medida isso foi um subproduto do esforço para acabar com a discriminação contra as mulheres em todos as suas dimensões. A conquista das igualdades formais, contudo, não levou a um aumento na parcela de mulheres beneficiárias da reforma, a qual permaneceu baixa até a metade da década de 1990. Isso aconteceu principalmente porque garantir na prática os direitos da mulher à terra não estava entre as prioridades dos movimentos sociais rurais. Além disso, o principal movimento social a determinar o passo da reforma agrária, o (MST, considerava classe e gênero questões incompatíveis. Próximo ao final da década de 1990, entretanto, havia uma consciência crescente de que deixar de reconhecer os direitos da mulher à terra era prejudicial ao desenvolvimento e à consolidação dos assentamentos da reforma agrária e, portanto, para o movimento. O crescente consenso, entre todos os movimentos sociais rurais, sobre a importância em assegurar o direito da mulher à terra, junto com um lobby efetivo, encorajou o Estado em 2001 a adotar mecanismos específicos para a inclusão de mulheres na reforma agrária.This article examines the evolution of the demand for women's land rights in the Brazilian agrarian reform through the prism of the three main rural social movements: the landless movement, the rural unions and the autonomous rural women's movement.

    2018-06-01

    Full Text Available Prussian blue (PB is a coordination polymer studied since the early 18th century, historically known as a pigment. PB can be prepared in colloidal form with a straightforward synthesis. It has a strong charge-transfer absorption centered at ~700 nm, with a large tail in the Near-IR range. Irradiation of this band results in thermal relaxation and can be exploited to generate a local hyperthermia by irradiating in the so-called bio-transparent Near-IR window. PB nanoparticles are fully biocompatible (PB has already been approved by FDA and biodegradable, this making them ideal candidates for in vivo use. While papers based on the imaging, drug-delivery and absorbing properties of PB nanoparticles have appeared and have been reviewed in the past decades, a very recent interest is flourishing with the use of PB nanoparticles as photothermal agents in biomedical applications. This review summarizes the syntheses and the optical features of PB nanoparticles in relation to their photothermal use and describes the state of the art of PB nanoparticles as photothermal agents, also in combination with diagnostic techniques.

    The synthesis of mesoporous Prussian blue analogues through a template-free methodology and the application of these mesoporous materials as high-performance cathode materials in sodium-ion batteries is presented. Crystalline mesostructures were produced through a synergistically coupled nanocrystal formation and aggregation mechanism. As cathodes for sodium-ion batteries, the Prussian blue analogues all show a reversible capacity of 65 mA h g-1 at low current rate and show excellent cycle stability. The reported method stands as an environmentally friendly and low-cost alternative to hard or soft templating for the fabrication of mesoporous materials.

    Highlights: · An electrochemical biosensor for detection of the plant hormone cytokinin. · Constitutive expression system for large-scale protein production. · CKX enzyme entrapment in sol-gel film on the surface of a PrB-modified electrode. · Prussian Blue as an electron mediator between the enzyme and the electrode. · The biosensor was sensitive to micromolar concentrations of several cytokinins. - Abstract: An electrochemical biosensor for detection of the plant hormone cytokinin is introduced. Cytokinin homeostasis in tissues of many lower and higher plants is controlled largely by the activity of cytokinin dehydrogenase (CKX, EC 1.5.99.12) that catalyzes an irreversible cleavage of N 6 -side chain of cytokinins. Expression of Arabidopsis thaliana CKX2 from Pichia pastoris was used to prepare purified AtCKX2 as the basis of the cytokinin biosensor. Prussian Blue (PrB) was electrodeposited on Pt microelectrodes prior to deposition of the enzyme in a sol-gel matrix. The biosensor gave amperometric responses to several cytokinins. These responses depended on the presence of both the enzyme and the Prussian Blue. Thus Prussian Blue must act as an electron mediator between the FAD centre in CKX2 and the Pt surface.

    Highlights: • Novel and inexpensive Prussian blue-N-graphene composite for hybrid battery- supercapacitor. • Prussian blue leads to a significant increase of the capacity. • Prussian blue leads to enhancement of cycling stability of N-graphene. - Abstract: Water-soluble Prussian blue nanoparticles (PB NPs) supported on nitrogen-doped graphene (N-graphene) with high dispersion was fabricated for high performance energy storage hybrid electrodes. An efficient loading of the PB NPs and nitrogen doping of graphene were achieved. The structure and morphology of the composite was determined by X-ray diffraction, transmission electron microscopy, Raman spectrometry and X-ray photoelectron spectrometry. The energy storage performance was assessed by cyclic voltammetry and galvanostatic charge/discharge techniques. The nanocomposite was fabricated as a hybrid battery-supercapacitor electrode and exhibited excellent performance with the highest capacity of 660 C g −1 at 1 A g −1 , which was higher than pure PB NPs and N-graphene electrodes. Moreover, the synergistic effect of N-graphene and the PB NPs prevented the N-graphene from shrinking and swelling and increased the cycle stability to 84.7% retention after 1500 cycles at 6 A g −1 , compared to the pure N-graphene.

    Research highlights: {yields} Cetyltrimethylammonium cations work as counter ions in Prussian blue film was observed and confirmed by cyclic voltammetry, Fourier transform infrared spectroscopy, X-ray powder diffraction measurements, scanning electronic microscopy and transmission electron microscope for the first time. {yields} Because the cetyltrimethylammonium cations in Prussian blue film are hydrophobic, the Prussian blue film is very stable even in alkali solution, which provides a technical basis for fabrication of stable biosensors. - Abstract: This work presents a photoinducedly electrochemical preparation of Prussian blue from a single sodium nitroprusside and insertion of cetyltrimethylammonium cations into Prussian blue as counter ions. The product of photoinducedly electrochemical reactions has a couple of voltammetric peaks at E{sup o} = 0.266 V in 0.2 mol l{sup -1} KCl solution, the measurements of X-ray powder diffraction and FT-IR spectroscopy show that it is Prussian blue (PB). The formation mechanism of a pre-photochemical reaction and subsequent electrochemical reaction is suggested. The cyclic voltammetric treatment of the freshly as-prepared PB film in 1.0 mmol l{sup -1} cetyltrimethylammonium (CTA) bromide solution leads to the insertion of cetyltrimethylammonium cations into the channels of Prussian blue, which substitutes for potassium ions as counter ions in Prussian blue. The Prussian blue containing CTA counter ions shows two couples of voltammetric peaks at E{sup o} = -0.106 V and E{sup o} = 0.249 V in 0.2 mol l{sup -1} KCl solution containing 1.0 mmol l{sup -1} cetyltrimethylammonium bromide. Compared with the electrochemical behaviors of KFeFe(CN){sub 6} in 0.1 mol l{sup -1} KOH alkali solution, CTAFeFe(CN){sub 6} shows relatively durable voltammetric currents due to the hydrophobic effects of cetyltrimethylammonium. The diffusion coefficients for CTA and potassium cations were estimated to be D{sub CTA} 1.25 x 10{sup -12} cm{sup 2} s

    Prussian carp ( Carassius gibelio ) are one of the most noxious non-native species in Eurasia. Recently, Prussian carp, a non-native freshwater fish species, were genetically confirmed in Alberta, Canada and have been rapidly expanding their range in North America since establishment. Given their rapid range expansion, there is an increasing need to determine how Prussian carp may impact native species. We assessed the severity of the Prussian carp invasion by (i) determining their impact on fish communities, (ii) assessing their impact on benthic invertebrate communities, (iii) evaluating if Prussian carp alter abiotic conditions, and (iv) identifying where we find higher abundances of Prussian carp. When Prussian carp were established, we found significant changes to the fish community. Correspondingly, the degree of impact to benthic invertebrate communities was related to the stage of invasion (none, early or recent), where changes in fish communities were significantly concordant with changes in benthic invertebrate communities. Finally, we found that higher abundances of Prussian carp were significantly associated with lower abundances of a majority of native fish species. Altogether, using three lines of evidence, we determine that Prussian carp can have wide-ranging impacts on freshwater ecosystems in North America, pressing the need for management intervention.

    England and Sweden have two of the most advanced systems of universal access to health care in the world. Both have begun major reforms based on similar principles. Universal access and finance from taxation are retained, but a measure of competition between providers of health care is introduced. The reforms therefore show a movement toward the kind of approach advocated by some in the United States. This article traces the origins and early results of the two countries' reform efforts.

    The purposes of this study were to asses the toxicological effects of stable cesium chloride, and investigate the possible therapeutic role of Prussian blue (PB) in adult male albino rats.Thirty two adult male albino rats were used in this study and classified to 4 groups (8 rats/group) as follows:1- Group one (G1): rats were considered as controls and kept on the commercial diet without any treatments.2-Group two (G2): treated with daily oral cesium chloride (50 mg/300 g body weight).3-Group three (G3): treated with daily oral Prussian blue (250 mg/rats).4-Group four (G4): treated with cesium chloride at a daily oral dose of 50 mg/300 g body weight + Prussian blue at a daily oral dose of 250 mg/rats.All animals were administered the CsCl and/or PB via intubation tube and the duration of this study was 35 consecutive days. Hemoglobin (Hb), hematocrit (Ht%), red blood cells (RBC), white blood cells (WBC), folic acid, vitamin B12, total protein, albumin, globulin, A/G ratio, ALT, AST, total bilirubin, alkaline phosphatase, blood glucose, urea, creatinine, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), sodium, potassium, calcium and inorganic phosphorous and body weight were determined in all groups.The data obtained revealed that the intake of stable cesium chloride in adult male rats caused significant decreases in the Hb, hematocrit, folic acid, vitamin B12 and potassium contents, with significant increases in WBC count, urea and creatinine levels and no effect on the other parameters. On the other hand, PB as a therapeutic agent caused significant amelioration in the changes produced by CsCl with variable degrees leading to the conclusion that the therapeutic agents might provide a protection against the toxicological effects of CsCl.

  6. Public Administration reforms and results

    2014-12-01

    Full Text Available Research on administrative reforms during the past thirty years indicates that reform efforts of countries differ. The Anglo Saxon states were at the forefront of the New Public Management movement while countries on mainland Europe were more hesitant and moved further towards the Neo-Weberian state. Academics have tried to explain different reform efforts within countries by looking at political, historical and cultural issues, values and economic factors to name just a few. Three hypotheses are put forward to explain reform efforts in different states. This research involves analysing the implementation of two different reform trends, New Public Management and the Neo-Weberian tradition. The analysis indicates that countries vary in their commitment to reform rather than in the emphasis on either New Public Management or the Neo-Weberian State. Decentralization, clear objectives and consultation with communities and experts are closely related to national reform efforts. However, Iceland does distinguish itself from Europe and the Nordic countries. The analysis reveals that although decentralization is high in the Icelandic system, autonomy of agencies does not have a strong relation to a varied use of administrative instruments. The second part of the article focuses on the results and achievements of reform programmes. The achievement of reform programmes are examined in relation to theories of bounded rationality, street level bureaucracy (bottom up and consensus decision making. Three hypotheses are presented and tested to explain what causes reforms programmes to be successful in some countries and not in others. The analysis reveals that countries are more likely to succeed if bounded rationality is applied with careful preparation and when stakeholders are consulted.

    2015-11-21

    Prussian blue (PB), the oldest synthetic coordination compound, is a classic and fascinating transition metal coordination material. Prussian blue is based on a three-dimensional (3-D) cubic polymeric porous network consisting of alternating ferric and ferrous ions, which provides facile assembly as well as precise interaction with active sites at functional interfaces. A fundamental understanding of the assembly mechanism of PB hetero-interfaces is essential to enable the full potential applications of PB crystals, including chemical sensing, catalysis, gas storage, drug delivery and electronic displays. Developing controlled assembly methods towards functionally integrated hetero-interfaces with adjustable sizes and morphology of PB crystals is necessary. A key point in the functional interface and device integration of PB nanocrystals is the fabrication of hetero-interfaces in a well-defined and oriented fashion on given substrates. This review will bring together these key aspects of the hetero-interfaces of PB nanocrystals, ranging from structure and properties, interfacial assembly strategies, to integrated hetero-structures for diverse sensing.

    Full Text Available Background. The aim of this study was to develop and characterize a nanoparticle-based image-contrast platform which is biocompatible, chemically stable, and accessible for radiolabeling with 201Tl. We explored whether this nanoparticle enhanced the T1 signal which might make it an MRI contrast agent as well. Methods. The physical properties of citrate-coated Prussian blue nanoparticles (PBNPs (iron(II;iron(III;octadecacyanide doped with 201Tl isotope were characterized with atomic force microscopy, dynamic light scattering, and zeta potential measurement. PBNP biodistribution was determined by using SPECT and MRI following intravenous administration into C57BL6 mice. Activity concentrations (MBq/cm3 were calculated from the SPECT scans for each dedicated volume of interest (VOI of liver, kidneys, salivary glands, heart, lungs, and brain. Results. PBNP accumulation peaked at 2 hours after injection predominantly in the kidneys and the liver followed by a gradual decrease in activity in later time points. Conclusion. We synthetized, characterized, and radiolabeled a Prussian blue-based nanoparticle platform for contrast material applications. Its in vivo radiochemical stability and biodistribution open up the way for further diagnostic applications.

    A large amount of radioactive cesium (Cs) has been released into natural environment following the nuclear accident in Fukushima, Japan in 2011. Much effort has been directed at capturing Cs and remediation of the contaminated environment. However, conventional sorbents, such as Prussian blue and zeolites cannot be easily recovered once spread into an open environment. Here, we develop new nano-sorbent based on the magnetic nanoparticles (MNP) functionalized with Prussian blue (PB) that possess both high Cs adsorption capacity (96 mg Cs/g sorbent) and large distribution coefficient (3.2 × 10 4 mL/g at 0.5 ppm Cs concentration). The developed sorbents possess good value of saturation magnetization (20 emu/g) allowing for rapid and ease of sorbent separation from the Cs solution after treatment using magnetic field. This Cs magnetic nano-sorbent can offer high potential for the use in large scale remediation of a Cs contaminated environment as well as the possibility of novel Cs decorporation drugs that can be magnetically assisted for accelerated excretion of radiocesium from the human body.

    2008-11-01

    A glucose biosensor based on polyvinylpyrrolidone (PVP) protected Prussian blue nanoparticles (PBNPs)-polyaniline/multi-walled carbon nanotubes hybrid composites was fabricated by electrochemical method. A novel route for PBNPs preparation was applied in the fabrication with the help of PVP, and from scanning electron microscope images, Prussian blue particles on the electrode were found nanoscaled. The biosensor exhibits fast current response (<6 s) and a linearity in the range from 6.7x10(-6) to 1.9x10(-3) M with a high sensitivity of 6.28 microA mM(-1) and a detection limit of 6x10(-7) M (S/N=3) for the detection of glucose. The apparent activation energy of enzyme-catalyzed reaction and the apparent Michaelis-Menten constant are 23.9 kJ mol(-1) and 1.9 mM respectively, which suggests a high affinity of the enzyme-substrate. This easy and controllable construction method of glucose biosensor combines the characteristics of the components of the hybrid composites, which favors the fast and sensitive detection of glucose with improved analytical capabilities. In addition, the biosensor was examined in human serum samples for glucose determination with a recovery between 95.0 and 104.5%.

    Prussian blue, ferric hexacyanoferrate is approved for (oral) treatment of internal contamination with radioisotopes of cesium or thallium. Cyanide makes up 35-40% of Prussian blue's molecular composition; thus, cyanide may be released during transit through the digestive tract under physiological pH conditions. The purpose of this study is to assess the long-term stability of Prussian blue drug products and active pharmaceutical ingredients and its impact on cyanide release. The study involves the determination and comparison of the loss in water content and cyanide released from Prussian blue under pH conditions that bracket human physiological exposure. Test samples of active pharmaceutical ingredient and drug product were stored for 10 years at ambient temperatures that mimic warehouse storage conditions. Water loss from Prussian blue was measured using thermogravimetric analysis. An in vitro physiological pH model that brackets gastric exposure and gastrointestinal transit was utilized for cyanide release. Prussian blue was incubated in situ at pH: 1.0, 5.0, and 7.0 @ 37°C for 1-24 h. Cyanide was measured using a validated colorimetric method by UV-Vis spectroscopy. Although the water content (quality attribute) of Prussian blue active pharmaceutical ingredient and drug product decreased by about 10.5% and 13.8%, respectively, since 2003, the cyanide release remained comparable. At pH of 7.0 for 24 h cyanide released from active pharmaceutical ingredient-1 was 21.33 ± 1.76 μg/g in 2004, and 28.45 ± 3.15 μg/g in 2013; cyanide released from drug product-1 was 21.89 ± 0.56 μg/g in 2004, and 27.31 ± 5.78 μg/g in 2013. At gastric pH of 1.0 and upper gastrointestinal pH of 5.0, the data for active pharmaceutical ingredients and drug products were also comparable in 2013. The cyanide release is still pH-dependent and follows the same trend as observed in 2003 with minimum release at pH of 5.0 and maximal release at pH of 1.0. In summary, this is the long

    Magnetic properties and hysteresis loops of a nano-ferrimagnetic surface-bulk Prussian blue analogues (PBA) have been studied by means of Monte Carlo simulations. We have reported the effects of the magnetic and the crystal fields, as well as the intermediate and the bulk couplings, the temperature and the size on the phase diagram, the magnetization, the susceptibility, the hysteresis loops, the critical and the discontinuity temperatures of the model. The thermal dependence of the coercivity and the remanent magnetization are also discussed. This study shows a number of characteristic behaviors, such as the discontinuities in the magnetizations, the existence of Q- and N-types behaviors in the Néel classification nomenclature and the occurrence of single and triple hysteresis loops with high number of step-like plateaus. The obtained results make ferrimagnetic surface-bulk PBA useful for technological applications such as thermo-optical recording.

    In this manuscript, the electrocatalytic reduction of hydrogen peroxides on Prussian blue (PB) modified nanoporous gold film (NPGF) electrode is described. The PB/NPGF is prepared by simple anodizing of a smooth gold film followed by PB film electrodeposition method. The morphology of the PB/NPGF electrode is characterized using scanning electron microscopy (SEM). The effect of solution pH and the scan rates on the voltammetric responses of hydrogen peroxide have also been examined. The amperometric determination of H2O2 shows two linear dynamic responses over the concentration range of 1μM-10μM and 10μM-100μM with a detection limit of 3.6×10(-7)M. Furthermore, this electrode demonstrated good stability, repeatability and selectivity remarkably. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Prussian blue analogies (PBAs are promising cathode materials for lithium ion (LIB and sodium ion (SIB secondary batteries, reflecting their covalent and nanoporous host structure. With use of synchrotron-radiation (SR X-ray source, we investigated the structural and electronic responses of the host framework of PBAs against Li+ and Na+ intercalation by means of the X-ray powder diffraction (XRD and X-ray absorption spectroscopy (XAS. The structural investigation reveals a robust nature of the host framework against Li+ and Na+ intercalation, which is advantageous for the stability and lifetime of the batteries. The spectroscopic investigation identifies the redox processes in respective plateaus in the discharge curves. We further compare these characteristics with those of the conventional cathode materials, such as, LiCoO2, LiFePO4, and LiMn2O4.

    The effects of applied transverse field on transition and compensation temperatures of the AB p C 1-p ternary alloy consisting of spins S A =3/2 , S B =2, and S C =5/2 are investigated by the use of a mean-field theory. The structure and the spin values of the model correspond to the Prussian blue analog of the type (Fe p II Mn 1-p II ) 1.5 [Cr III (CN) 6 ].nH 2 O. We find that two or even three compensation points may be induced by a transverse field for the system with appropriate values of the parameters in the model Hamiltonian. In particular, the influence of a transverse field on the compensation point in the ground state is examined

    A facile approach for the synthesis of ultralight iron oxide hierarchical structures with tailorable macro- and mesoporosity is reported. This method entails the growth of porous Prussian blue (PB) single crystals on the surface of a polyurethane sponge, followed by in situ thermal conversion of PB crystals into three-dimensional mesoporous iron oxide (3DMI) architectures. Compared to previously reported ultralight materials, the 3DMI architectures possess hierarchical macro- and mesoporous frameworks with multiple advantageous features, including high surface area (ca. 117 m(2) g(-1)) and ultralow density (6-11 mg cm(-3)). Furthermore, they can be synthesized on a kilogram scale. More importantly, these 3DMI structures exhibit superparamagnetism and tunable hydrophilicity/hydrophobicity, thus allowing for efficient multiphase interfacial adsorption and fast multiphase catalysis. © 2014 WILEY-VCH Verlag GmbH & Co.

    Graphical abstract: Prussian Blue (PB) cubes supported on nitrogen-doped graphene sheets (NGS) were synthesized using a simple and scalable method, and the utilization of the PB-NGS hybrid as an efficient superoxide dismutase mimic in the electrochemical sensing of O 2 ·− was demonstrated. - Highlights: • Facile and scalable synthesis of Prussian Blue cubes supported on nitrogen-doped graphene; • Nitrogen-doped graphene supported Prussian Blue as an efficient biomimetic superoxide dismutase for the electrocatalytic sensing of superoxide anion; • Good sensitivity, excellent selectivity and attractive long-term stability for superoxide anion sensing. - Abstract: Considering the double-sided roles of superoxide anion radical, monitoring of its track in living systems is attracting increasing academic and practical interest. Here we synthesized Prussian Blue (PB) cubes that were supported on nitrogen-doped graphene sheets (NGS) using a facile and scalable method, and explored their potential utilization in the electrochemical sensing of superoxide anion. As an efficient superoxide dismutase mimic, direct electron transfer of the prepared PB-NGS hybrid immobilized on a screen-printed gold electrode was harvested in physiological media. With the bifunctional activities, the synthetic mimic could catalyze the dismutation of superoxide anion via the redox cycle of active iron. By capturing the electro-reduction amperometric responses of superoxide anion radical to hydrogen peroxide in the cathodic polarization, highly sensitive determination (a sensitivity of as high as 0.32 μA cm −2 μM −1 ) of the target was achieved, with no interference from common coexisting species including ascorbic acid, dopamine, and uric acid observed. Compared to natural superoxide dismutases, the artificial enzyme mimic exhibited favorable activity stability, indicating its promising applications in the in vivo long-term monitoring of superoxide anion

    We present a comprehensive study of the structural properties and the thermal expansion behavior of 17 different Prussian Blue Analogs (PBAs) with compositions M II 3 [(M') III (CN) 6 ] 2 .nH 2 O and M II 2 [Fe II (CN) 6 ].nH 2 O, where M II =Mn, Fe, Co, Ni, Cu and Zn, (M') III =Co, Fe and n is the number of water molecules, which range from 5 to 18 for these compounds. The PBAs were synthesized via standard chemical precipitation methods, and temperature-dependent X-ray diffraction studies were performed in the temperature range between -150 deg. C (123 K) and room-temperature. The vast majority of the studied PBAs were found to crystallize in cubic structures of space groups Fm3-bar m, F4-bar 3m and Pm3-bar m. The temperature dependence of the lattice parameters was taken to compute an average coefficient of linear thermal expansion in the studied temperature range. Of the 17 compounds, 9 display negative values for the average coefficient of linear thermal expansion, which can be as large as 39.7x 1 0 -6 K -1 for Co 3 [Co(CN) 6 ] 2 .12H 2 O. All of the M II 3 [Co III (CN) 6 ] 2 .nH 2 O compounds show negative thermal expansion behavior, which correlates with the Irving-Williams series for metal complex stability. The thermal expansion behavior for the PBAs of the M II 3 [Fe III (CN) 6 ] 2 .nH 2 O family are found to switch between positive (for M=Mn, Co, Ni) and negative (M=Cu, Zn) behavior, depending on the choice of the metal cation (M). On the other hand, all of the M II 2 [Fe II (CN) 6 ].nH 2 O compounds show positive thermal expansion behavior. - Graphical Abstract: The structure of Prussian Blue analogs (PBAs) consists of two types of metal centered octahedral units connected by cyanide ligand.

    Histamine (HA) is a biogenic amine that can accumulate to high concentration levels in food as a result of microbial activity and can cause toxic effects in consumers. In this work, a portable electrochemical immunosensor capable of detecting HA with high sensitivity and selectivity was developed. Prussian blue-chitosan-gold nanoparticle (PB-CS-AuNP) nanocomposite films with excellent biocompatibility were synthesized and characterized by scanning electron microscopy and energy dispersive X-ray analysis. The PB-CS-AuNP were coated onto a screen-printed electrode by one-step electrodeposition and used to conjugate the HA ovalbumin conjugate (HA-Ag). HA was determined by a competition between the coating HA-Ag and the HRP labeled HA antibody (HRP-HA-Ab). After careful optimization of assay conditions and Box-Behnken analysis, the developed immunosensor showed a linear range from 0.01 to 100μg/mL for HA in fish samples. The average recoveries from spiked samples ranged from 97.25% to 105%. The biosensor also showed good specificity, reproducibility, and stability, indicating its potential application in monitoring HA in a simple and low cost manner. Copyright © 2017 Elsevier B.V.

    Seventy male albino rats of two ages: growing (2-months age, 102 + 10 g /rat) and adults (4- months age, 280 + 15 g / rat) were used in this study. The rats were fed on a balanced diet (21% crude proteins, 3% crude fats and 4% crude fibers). The treatments of oral administration of a single dose (3700 Bq/growing rat and 7400 Bq/adult rat) of 137 Cs ( 137 Cs Cl salt) and prussian blue (PB, 300 mg/kg body weight/day for 60 days) were as the following combinations: [1] without 137 Cs or PB, [2] 137 Cs only, [3] PB only, [4] PB one day before 137 Cs, [5] PB immediately after 137 Cs, [6] PB one day after 137 Cs, and [7] PB one week after 137 Cs. All of body weight, total body water (TBW), fat-free body (FFB), total body fat (TBF), fat-free dry body (FFDB), total body protein (TBP), and total body ash (TBA). The data revealed that: adult rats had a significant (P 137 Cs treatment caused decreases in final body weight; % change of body weight, TBW, FFB, FFDB, TBP, TBA. In both growing and adult rats, PB administration, only before or at the same time of irradiation, could eliminate the effects of 137 Cs-gamma irradiation on : final body weight, % change in body weight, FFB, FFDB, TBP. However, PB administration, one or seven days post treatment, eliminated 137 Cs treatments effects on TBF

    We describe an electrochemical sensor for hydrogen peroxide (H 2 O 2 ) that is making use of Prussian Blue (PB) electrodeposited on a macroporous (mp) gold skeleton electrode. An mp-Cu film was first prepared as a template and the converted into an mp-Au film through a replacement reaction without destructing the structure. Next, a layer of PB was electrochemically deposited on the surface of the mp-Au film. The surface morphology of the electrode was characterized by scanning electron microscopy. Attenuated total reflection infrared spectroscopy and X-ray photoelectron spectroscopy were applied to confirm the structural features. The mp-PB/Au film electrode displays high electro-catalytic activity for the reduction of H 2 O 2 at a working potential of −50 mV (vs. Ag/AgCl) and is very stable. It has a linear response to H 2 O 2 in the 50 μM to 11.3 mM concentration range and a sensitivity of 767 μA∙mM −1 cm −2 . The electrode also revealed good selectivity in the presence of electro-active species such as ascorbic acid and uric acid. (author)

    Despite transition metal (TM) K-edge x-ray magnetic circular dichroism (XMCD) seems an interesting tool to get magnetic and structural information at the atomic scale, the effects originating this signal are still poorly understood. We thus initiated a deep investigation of the TM K-edge XMCD using Prussian Blue analogs (PBA) as model-compounds. In a recent study of the NiFe PBA family, we demonstrated that the XMCD signals at the TM K-edges strongly vary with external (mechanical) or internal (chemical) pressure and so that they are highly sensitive to small structural distortions. Following these first results, we extended this approach to the MnFe and CoFe families to evaluate the effect of electronic parameters (number of unpaired electrons of the M II TM) on the XMCD signal. All the results set milestones in the disentanglement of the components originating the XMCD signals at the K-edge of TM and will eventually help in a better understanding of the photomagnetic properties of PBAs.

  16. Characterization of the Pseudocapacitive Nature of Surface Bound Prussian Blue Analogues

    Clark, Daniel; Hampton, Jennifer

    With the increased use of intermittent renewable energy sources, more efficient methods of energy storage must be explored. Electrochemical capacitors provide a larger volumetric charge density than physical capacitors while maintaining fast charge and discharge rates. Prussian Blue analogues (nickel and cobalt hexacyanoferrate) are ideal pseudocapacitors for frequent charge and discharge cycles since the crystalline structure does not physically change during switching, causing less stress on the film. This project examines the charge transfer and diffusion coefficients for nickel and nickel-cobalt thin films modified with potassium hexacyanoferrate. The films were examined using a scanning electron microscope, an atomic force microscope and an electrochemical workstation to determine their composition, topography and psuedocapacitive nature. Preliminary data suggest that nickel-cobalt films have a larger quantity of charge and have a lower diffusion coefficient per charge than nickel films.

    Prussian blue (PB) was immobilized in alginate capsules. The composite sorbent was used for the recovery of Tl(I) ions from slightly acidic solutions: optimum pH being close to 4. The sorption isotherm can be described by the bi-site Langmuir sorption isotherm. This means that the metal ion can be bound through two different sorption sites: one having a strong affinity for Tl(I) (probably PB), the other having a lower affinity (probably the encapsulating material). The kinetics are described by either the pseudo-second order rate equation or the Crank's equation (resistance to intraparticle diffusion). The ionic strength (increased by addition of NaCl, KCl or CaCl₂) slightly decreased sorption capacity. The SEM-EDX analysis of PB-alginate capsules (before and after Tl(I) sorption) shows that the PB is homogeneously distributed in the capsules and that all reactive groups remain available for metal binding.

    Historic Prussian blue (PB) pigment is easily obtained as an insoluble precipitate in quantitative yield from an aqueous mixture of Fe 3+ and [Fe II (CN) 6 ] 4- (Fe 2+ and [Fe III (CN) 6 ] 3- ). It has been found that the PB pigment is inherently an agglomerate of 10-20 nm nanoparticles, based on powder x-ray diffraction (XRD) line broadenings and transmission electron microscopy (TEM) images. The PB pigment has been revived as both organic-solvent-soluble and water-soluble nanoparticle inks. Through crystal surface modification with aliphatic amines, the nanoparticles are stably dispersed from the insoluble agglomerate into usual organic solvents to afford a transparent blue solution. Identical modification with [Fe(CN) 6 ] 4- yields water-soluble PB nanoparticles. A similar ink preparation is applicable to Ni-PBA and Co-PBA (nickel and cobalt hexacyanoferrates). The PB (blue), Ni-PBA (yellow), and Co-PBA (red) nanoparticles function as three primary colour inks

    Extracellular fungal flavocytochrome cellobiose dehydrogenase (CDH) is a promising enzyme for both bioelectronics and lignocellulose bioconversion. A selective high-throughput screening assay for CDH in the presence of various fungal oxidoreductases was developed. It is based on Prussian Blue (PB) in situ formation in the presence of cellobiose (<0.25 mM), ferric acetate, and ferricyanide. CDH induces PB formation via both reduction of ferricyanide to ferrocyanide reacting with an excess of Fe³⁺ (pathway 1) and reduction of ferric ions to Fe²⁺ reacting with the excess of ferricyanide (pathway 2). Basidiomycetous and ascomycetous CDH formed PB optimally at pH 3.5 and 4.5, respectively. In contrast to the holoenzyme CDH, its FAD-containing dehydrogenase domain lacking the cytochrome domain formed PB only via pathway 1 and was less active than the parent enzyme. The assay can be applied on active growing cultures on agar plates or on fungal culture supernatants in 96-well plates under aerobic conditions. Neither other carbohydrate oxidoreductases (pyranose dehydrogenase, FAD-dependent glucose dehydrogenase, glucose oxidase) nor laccase interfered with CDH activity in this assay. Applicability of the developed assay for the selection of new ascomycetous CDH producers as well as possibility of the controlled synthesis of new PB nanocomposites by CDH are discussed.

    Graphical abstract: - Highlights: • Pt/Prussian blue/graphene catalyst was easily synthesized by the sequential electrodeposition method. • Prussian blue can promote the homogeneous growth of small Pt nanoparticles. • The as-made catalyst exhibited enhanced electro-catalytic performance for methanol oxidation. • The interplay of Prussian blue and Pt plays a significant role in reducing CO poisoning of the catalyst. - Abstract: Graphene nanosheets (GN) are modified by electrodeposition of Prussian blue (PB) followed by shape-regulated depositing of small Pt nanoparticles via the interaction between PB and PtCl 6 2− to form a novel catalyst Pt/PB/GN. The Pt/PB/GN composite exhibits significantly enhanced electrocatalytic activity with a mass activity of 445 mA mg −1 Pt (at 0.68 V vs. SCE) and high stability towards methanol oxidation. The high catalytic activity can be attributed to the unique porous architecture and peculiar electrical property of Prussian blue integrated with graphene layers which can not only well accommodate Pt nanoparticles but also provide multidimensional pathways to facilitate the mass and electron transport for methanol oxidation. This strategy can be readily extended to fabrication of other graphene-based hybrid supports for precious metal catalysts in fuel cell applications

    Some industries usually reduce the concentration of protons in acidic wastewater by conducting neutralization reactions and/or adding seawater to industrial effluents. This work proposes a novel electrochemical system that can harvest energy originating from entropic changes due to alteration in the concentration of sodium ions along wastewater treatment. Preparation of a self-assembled material from nickel Prussian blue analogue (NPBA) was the first step to obtain such electrochemical system. Investigation into the electrochemical properties of this material helped to evaluate its potential use in neutralization and mixing entropy batteries. Assessment of parameters such as the potentiodynamic profile of the current density as a function of the concentration of protons and sodium ions, charge capacity, and cyclability as well as the reversibility of the sodium ion electroinsertion process aided estimation of the energy storage efficiency of the system. Frequency-domain measurements and models and the proposed charge compensation mechanism provided the rate constants at different dc potentials. After each charge/discharge cycle, the NPBA electrode harvested 12.4 kJ per mol of intercalated sodium ion in aqueous solutions of NaCl at concentrations of 20 mM and 3.0 M. The full electrochemical cell consisted of an NPBA positive electrode and a negative electrode of silver particles dispersed in a polypyrrole electrode. This cell extracted 16.8 kJ per mol of intercalated ion after each charge/discharge cycle. On the basis of these results, the developed electrochemical system should encourage wastewater treatment and help to achieve sustainable growth.

    After the Fukushima nuclear accident, tremendous efforts were made to treat radiocesium, radiostrontium, and other radioactive materials. For the first time, we demonstrate that a TiO 2 photocatalyst can significantly enhance Cs adsorption by Prussian blue-deposited TiO 2 (PB/TiO 2 ) under UV irradiation. In this study, we synthesized PB/TiO 2 using the photodeposition method. After the Cs ions were adsorbed on the PB/TiO 2 in darkness, we then exposed the PB/TiO 2 to UV light irradiation. This resulted in a further increase in Cs ion adsorption of more than 10 times the amount adsorbed in darkness. This photocatalytic-enhanced adsorption of Cs ions was not observed on PB mixed with SiO 2 , nor under visible light irradiation. We investigated the effects of PB concentration, PB/TiO 2 concentration, and gas purging on both dark and photocatalytic-enhanced adsorption of Cs ions by PB/TiO 2 . Based on the results, we suggest that the photocatalytic-enhanced adsorption of Cs ions on PB/TiO 2 is due to photocatalytic reduction of PB, which leads to additional adsorption of Cs ions. The change in solution color before and after the reaction, and the change in solution pH in the dark and during UV irradiation strongly support this suggestion. The photocatalytic-enhanced adsorption of Cs ions was equivalent during radioactive 137 Cs removal, indicating important applications for pollutant removal from contaminated water.

    Full text: Prussian blue (PB) is one the most important compounds used in electrochemical sensing of molecular targets as H{sub 2}O{sub 2}. Many diseases or biochemical abnormalities can be diagnosed by analysis of H{sub 2}O{sub 2}. The properties found in PB comes from the electronic structure of this material which is formed by Fe{sup 2+} bonded to iron Fe{sup 3+} by cyanide bridged arranged in a 3D structure. Furthermore, the intervalence observed allows to achieve different levels of oxidation in the same process[1]. The challenge in this area is how to control and modulate specific features of PB. Because of this, we are interested in evaluating how the ligand Nmethylpyrazinium affects the structure and reactivity of the N-methylpyraziniumpentacyanidoferrate(II)(PCF) and its PB corresponding. According to XRD, the PB obtained from PCF produces an amorphous structure instead of the highly ordered structure of PB obtained by classical methods. The stoichiometry of formation of the PB(classic) obtained by the Job's method is 1: 1 (Fe(III): [Fe(CN){sub 6}]{sup 4-}), on the other hand, in PB-PCF the stoichiometry is 1: 2 (Fe(III):PCF). The reported features cause differences in the oxidation potential of the films, PB(classic) Eox=0.167V and PB-PCF Eox=0.219V. In terms of sensing of H{sub 2}O{sub 2}, the PB(classic) presented LOD= 1.2 10{sup -4} M and PB-mpz LOD= 5.8 10{sup -5}M. We have concluded that different sources of iron complexes cause alterations in the organization and electronic structure of the PB. Reference: [1] B. M. Pires, S. A. V. Jannuzzi, A. L. B.

    The Italian physician and botanist Prospero Alpini (1553-1617) is considered as one of the most famous 16th Century Italian botanists having explored the plant species of Egypt and the Near East. Alpinis best-known works as for example De medicina Egyptiorum (Venetijs 1591) or De plantis Aegypti liber (Venetijs 1592), however, wouldn't certainly have been made possible without the influence of his academic teacher, the Prussian physician and botanist Melchior Wieland (ca. 1520-1589), having been applied director of the botanical garden of Padua in 1561. This study is therefore dedicated to the life, academic career, works and reception of this nearly forgotten botanist.

  16. Kristeva's Reformation

    Full Text Available In my brief remarks, I consider what it means to return and rebind—that is to say, the significance of the re for Kristeva’s thought.  Kristeva does not just talk about binding or birth, or unbinding or death, but rather rebinding and rebirth, suggesting that it is a retrospective return rather than an original moment that is crucial.  The most significant moment, then, is not the moment of imaginary plenitude, nor the moment of originary loss, but rather the moment of rebirth that comes through rebinding after the loss of plenitude.  Indeed, Kristeva’s insistence on re-turning suggests that there is no originary moment of plenitude nor of castration or loss, but rather a constant movement of compensation for a recurrent loss.  By emphasizing rebinding and rebirth, she underscores not the loss as cutting wound but rather the healing power of signification, always already inherent within loss.  The flip-side of separation is reattachment.  And rather than just focus on the separation or cut, Kristeva looks to that which allows us to rebind and reattach in order to create relations that sustain us.  Both unbinding and binding are necessary for rebinding.  Thus, by focusing on rebinding, Kristeva insists on the process of unbinding and binding, and the oscillation between them.

    Full Text Available Since the reformation and democratization movement in 1998, Indonesians have faced a chronic corruption problem. At the beginning of reformation era in 1998 to fight against corruption, the Indonesian government reforms the organization structure of the Indonesia Police to be an independent body separated from the Military organization. The police reforms begun in 1999 and got legal foundation with Act No. 2/2002. However, since fourteen years, the level of police reform has not yet succeed because of low community satisfaction on police service and the intense conflicts always occur whenever ACA investigates the case of corruptions conducted by police leaders. Three conflicts between police institution and ACA have taken placed. By using institutionalism approach, this research focus on the reform in police themselves are major actors on how reforms are organized and managed. This study is interpretative in nature gained only through social constructions such as language, consciousness, shared meanings, documents, tools, and other artefacts’. This finding revealed that this unsuccessful institutionalization process took place in a context of the main task of police for communicty service. Second, the study has demonstrated that three concepts from institutional theory as aforementioned provided vocabularies and insights to explain the phenomenon under study.

    2014-04-01

    Full Text Available The neorealist theory developed by Kenneth Waltz is one of the most important theories of international relations. The most significant predictions of his theory is that the balancing behavior is a systemic product, which will occur regularly in international relations whether the states want it or not. This papers aims to bring a critical perspective on the concept of balancing as it is developed by Waltz. Therefore, the prediction made by Waltz will be tested against the international system developed at the end of the nineteenth century, particularly after the Franco-Prussian War. Finally, it will be concluded that the parsimony that is characterizing Waltz’s theory is inaccurate because it makes it on one hand irrefutable and on the other hand, it makes it inconsistent.

  7. Thermal oxidation of cesium loaded Prussian blue as a precaution for exothermic phase change in extreme conditions

    Cesium adsorbed Prussian blue is studied for the thermal oxidation. The TG-DTA shows exothermic phase change of micro aggregates of nano-PB at above 270°C. For this reason, Cs loaded PB was heated between 180 to 260°C. Heating at 180 removed only the water. Neither the oxidation of Iron nor the removal of cyanide is observed at this temperature. Oxidation of cyanide is observed upon heating above 200°C while loaded Cs is released after heating at >250°C followed by washing with water. Thermal oxidation between 200 to 220°C for more than 2 h showed control on exothermic phase change and loaded Cs is also not solubilized. (author)

    Full Text Available Purpose. To provide the biological assessment of the silver Prussian carp (Carassius auratus gibelio (Bloch, 1782 commercial stock of the Dnieper-Bug estuary in the conditions of the transformed Dnieper river flow. Methodology. During the analysis of the biological state of the Prussian carp commercial stock, the main attention was given to the dynamics of age and sexual structure, length-weight growth rate, absolute fecundity and condition factor. The basic data were collected during the work of control-observation stations of the Institute of Fisheries in the Dnieper-Bug estuary during the current century. The collection and processing of ichthyological materials were performed in accordance with the generally accepted methodologies. Findings. The analysis showed that during the current century, the age structure of the Prussian carp of the Dnieper-Bug estuary was the most labile among other commercial cyprinids. It was found that as a result of an increase in the right wing of the age series, there was a gradual increase of the mean weighted age of its commercial stock. At the beginning of studies (2001-2002, the core of the stock was formed by age-3-6 fish (up ; however in subsequent years, a displacement of dominant groups toward the dominance of age-4-7 fish (more than 80% of the total stock was observed. At the same time, the relative number of age-3 fish (recruits was at a relatively high level – up to 10.6%. The linear growth varied more intensively until the age-5, but it reduced with ageing and did not show high variability. The body weight most variable was in age-4 fish (Cv=9.62%. The noted insignificant deviations in the body weight growth rate of the right wing of the age series was due to stable predominance of females in the stock structure, which were characterized by a variability of the mean weight as a result of different development of gonads. The dynamics of the age-related changes in the condition factor indicated on a

    Highlights: • Preparation of biocompatible chitosan–alginate electrode. • The synergism between Acetobacter aceti and Gluconobacter roseus. • Better biofilm formation and enhanced electricity generation. • Immobilized Prussian blue system replaces the conventional ferricyanide system. - Abstract: This work is aimed at finding new strategies for the modification of anode and cathode that can lead to improved performance of microbial fuel cells (MFCs). The electrochemical deposition of chitosan onto carbon felt followed by further modification with alginate led to the formation of a biocompatible platform for the prolific growth of microorganisms on the anode (Chit–Alg/carbon felt anode). The novel modification strategy for the formation of Prussian blue film, on the electrochemically deposited chitosan layer, has helped in circumventing the disadvantages of using ferricyanide in the cathode compartment and also for improving the electron transfer characteristics of the film in phosphate buffer. The anode was tested for its efficacy with four different substrates viz., glucose, ethanol, acetate and grape juice in a two compartment MFC. The synergistic effect of the mixed culture of Acetobacter aceti and Gluconobacter roseus was utilized for current generation. The electrocatalytic activity of the biofilm and its morphology were characterized by cyclic voltammetry and scanning electron microscopy, respectively. The power densities were found to be 1.55 W/m 3 , 2.80 W/m 3 , 1.73 W/m 3 and 3.87 W/m 3 for glucose, ethanol, acetate and grape juice, respectively. The performance improved by 20.75% when compared to the bare electrode

    Full Text Available Natural chelators from some natural sources have been shown their detox heavy metals ability in human and animals. So the present study was carried out to histological compare the aspect of kidney tissue of Prussian carp’s specimens, subjected to chronic Cd intoxication with and without garlic, cilantro and chlorella dietary supplementation. 150 Prussian carps, with weight of 10-12 g were divided according to the following treatments for 21 days: C (without treatment, E1 (10 ppm Cd into water as CdCl2 x ½ H2O, E2 (10 ppm Cd into water+2% lyophilized garlic in feed, E3 (10 ppm Cd into water+2% lyophilized cilantro in feed, E4 (10 ppm Cd into water+2% lyophilized chlorella in feed. The potential protective effect of the three lyophilized products against the impact of cadmium toxicity was evaluated in terms of hystopathological characteristics. For this purpose, fragments of kidney were removed and routinely processed at the end of experimental period and analyzed in light microscopy. A specific QuickPHOTO Micro 2.2 software has been used for the histological study. Tissue alterations were assessed using the histopathological score ranging from - to +++ depending on the degree and extend of lesions: (- none, (+ mild occurrence, (++ moderate occurrence, (+++ severe occurrence. Cd contamination has definitely affected the kidney, inducing severe damage in its structure as: swelling and hypertrophy of tubules with nuclear deterioration, pyknosis and cariorrexis, nucleus and cytoplasm degeneration, capillary ectasia and congestions. Active compounds from garlic and cilantro powder have shown the most chelating and antioxidant potential, leading to the evident recovery of kidney architecture, while the response at chlorella treatment was less effective than E2 group and without significant difference compared with E3 group.

    2017-11-01

    Full Text Available Conventional ion-selective electrodes with a liquid junction have the disadvantage of potential drift. All-solid-state ion-selective electrodes with solid contact in between the metal electrode and the ion-selective membrane offer high capacitance or conductance to enhance potential stability. Solution-casted chitosan/Prussian blue nanocomposite (ChPBN was employed as the solid contact layer for an all-solid-state sodium ion-selective electrode in a potentiometric sodium ion sensor. Morphological and chemical analyses confirmed that the ChPBN is a macroporous network of chitosan that contains abundant Prussian blue nanoparticles. Situated between a screen-printed carbon electrode and a sodium-ionophore-filled polyvinylchloride ion-selective membrane, the ChPBN layer exhibited high redox capacitance and fast charge transfer capability, which significantly enhanced the performance of the sodium ion-selective electrode. A good Nernstian response with a slope of 52.4 mV/decade in the linear range from 10−4–1 M of NaCl was observed. The stability of the electrical potential of the new solid contact was tested by chronopotentiometry, and the capacitance of the electrode was 154 ± 4 µF. The response stability in terms of potential drift was excellent (1.3 µV/h for 20 h of continuous measurement. The ChPBN proved to be an efficient solid contact to enhance the potential stability of the all-solid-state ion-selective electrode.

    Imaging modalities utilize contrast agents to improve morphological visualization and to assess functional and molecular/cellular information. Here we present a new type of nanometer scale multi-functional particle that can be used for multi-modal imaging and therapeutic applications. Specifically, we synthesized monodisperse 20 nm Prussian Blue Nanocubes (PBNCs) with desired optical absorption in the near-infrared region and superparamagnetic properties. PBNCs showed excellent contrast in photoacoustic (700 nm wavelength) and MR (3T) imaging. Furthermore, photostability was assessed by exposing the PBNCs to nearly 1,000 laser pulses (5 ns pulse width) with up to 30 mJ/cm2 laser fluences. The PBNCs exhibited insignificant changes in photoacoustic signal, demonstrating enhanced robustness compared to the commonly used gold nanorods (substantial photodegradation with fluences greater than 5 mJ/cm2). Furthermore, the PBNCs exhibited superparamagnetism with a magnetic saturation of 105 emu/g, a 5x improvement over superparamagnetic iron-oxide (SPIO) nanoparticles. PBNCs exhibited enhanced T2 contrast measured using 3T clinical MRI. Because of the excellent optical absorption and magnetism, PBNCs have potential uses in other imaging modalities including optical tomography, microscopy, magneto-motive OCT/ultrasound, etc. In addition to multi-modal imaging, the PBNCs are multi-functional and, for example, can be used to enhance magnetic delivery and as therapeutic agents. Our initial studies show that stem cells can be labeled with PBNCs to perform image-guided magnetic delivery. Overall, PBNCs can act as imaging/therapeutic agents in diverse applications including cancer, cardiovascular disease, ophthalmology, and tissue engineering. Furthermore, PBNCs are based on FDA approved Prussian Blue thus potentially easing clinical translation of PBNCs.

    The author describes the development of protest movements in postwar Germay and outlines two essential overlapping 'flow cycles'. The first of these was characterised by the restaurative postwar years. It culminated and ended in the students' revolt. This revolt is at the same time the start of a second cycle of protest which encompasses all subsequent individual movement and is initated by an economic, political and sociocultural procrastination of modernisation. This cycle culminates in the late 70s and early 80s and clearly lost momentum over the last few years. The follwoing phases and themes are described profoundly: against restauration and armament in the 1950; the revolutionary impatience of the students' movement, politisation of everyday life by the womens' movement and citizens' action groups, antinuclear- and ecological movement, differentiation and stabilisation of the movement in the 70s and 80s; break-up and continuity in the German protest behaviour. The paper contains a detailed chronicle of protest activities since 1945. (orig.) [de

    Contemporary science has brought about technological advances and an unprecedented understanding of the natural world. However, there are signs of dysfunction in the scientific community as well as threats from diverse antiscience and political forces. Incentives in the current system place scientists under tremendous stress, discourage cooperation, encourage poor scientific practices, and deter new talent from entering the field. It is time for a discussion of how the scientific enterprise can be reformed to become more effective and robust. Serious reform will require more consistent methodological rigor and a transformation of the current hypercompetitive scientific culture.

    Highlights: • Prussian blue microparticles incorporated in chitin sponges. • Efficient Cs(I) sorption after water absorption by dry hybrid sponge. • Water draining after sorption for metal confinement and water decontamination. • High decontamination factors and distribution coefficients for Cs(I) and {sup 137}Cs(I). • Effect of freezing conditions on porous structure and textural characterization. - Abstract: Prussian blue (i.e., iron[III] hexacyanoferrate[II], PB) has been synthesized by reaction of iron(III) chloride with potassium hexacyanoferrate and further immobilized in chitosan sponge (cellulose fibers were added in some samples to evaluate their impact on mechanical resistance). The composite was finally re-acetylated to produce a chitin-PB sponge. Experimental conditions such as the freezing temperature, the content of PB, the concentration of the biopolymer and the presence of cellulose fibers have been varied in order to evaluate their effect on the porous structure of the sponge, its water absorption properties and finally its use for cesium(I) recovery. The concept developed with this system consists in the absorption of contaminated water by the composite sponge, the in situ binding of target metal on Prussian blue load and the centrifugation of the material to remove treated water from soaked sponge. This material is supposed to be useful for the fast treatment of accidental dumping of Cs-contaminated water.

  4. Reforming Romanian energy policy

    International Nuclear Information System (INIS)

    Perkins, S.

    1993-01-01

    Success in reforming energy sector depends on the implementation of the programme of economic reform agreed in February 1993. The difficulty of the negotiations between the International Monetary Fund and the Romanian government reflects the wider difficulties faced by the economy as a whole. They can be blamed in part on the legacy of uneconomic and inflexible industrial development and in part on opposition from interest groups which stand to lose from reform. Nonetheless, in spite of hesitant approach, the government does appear committed to the economic reform necessary to establish a market-oriented economy. But as the danger of a financial crisis engendered by the inadequately supported short-term borrowing of foreign exchange becomes urgent, the question is whether economic reform can be now implemented fast enough to protect economic enterprises and saving from a debt crisis. The scope for further delay in implementing the 1993 economic reform programme is fast disappearing. Procrastination should not be allowed to threaten the success of the reforms achieved in the energy and other sectors of the economy. 8 refs., 2 figs

    A non-catalytic recuperative reformer has a flue gas flow path for conducting hot flue gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is embedded in the flue gas flow path to permit heat transfer from the hot flue gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, extended surfaces of metal material such as stainless steel or metal alloy that are high in nickel content are included within at least a portion of the reforming mixture flow path.

    Full Text Available In this work, we presented a simple method to synthesize magnetite Prussian blue nano-composites (Fe3O4-PB through one-pot hydrothermal process. Subsequently, the obtained nano-composites were used to fabricate a facile and effective glucose biosensor. The obtained nanoparticles were characterized using transmission electron microscopy, scanning electron microscopy, Fourier-transform infrared spectroscopy, UV-vis absorbance spectroscopy, cyclic voltammetry and chronoamperometry. The resultant Fe3O4-PB nanocomposites have magnetic properties which could easily controlled by an external magnetic field and the electro-catalysis of hydrogen peroxide. Thus, a glucose biosensor based on Fe3O4-PB was successfully fabricated. The biosensor showed super-electrochemical properties toward glucose detection exhibiting fast response time within 3 to 4 s, low detection limit of 0.5 µM and wide linear range from 5 µM to 1.2 mM with sensitivity of 32 µA∙mM−1∙cm−2 and good long-term stability.

    Graphical abstract: - Highlights: • PB-based ECD employed micro-patterned FTO electrode was fabricated. • Effect of interface morphology on electrochromic characteristics was examined. • Electrochromic properties were enhanced by employing a patterned interface. - Abstract: The effect of interface morphology on electrochromic characteristics was examined for an electrochromic device (ECD). Micro-patterned fluorine-doped tin oxide (FTO) films were fabricated using a photolithography process. Prussian blue (PB) films were then deposited on the patterned FTO films. The surface areas of both PB films and FTO films were increased by patterning. ECDs were assembled using patterned PB/FTO films as the electrochromic electrode, bare FTO films as the counter electrode, and an electrolyte containing LiClO 4 salt. The increased effective surface area of the patterned PB/FTO electrode boosted the mobility of ions at the interphase between the electrolyte and PB electrode, and the electron transfer between PB films and FTO films. As a result, electrochromic properties such as transmittance and response time were significantly improved by employing the patterned FTO films as the transparent conductive oxide layer of the electrochromic electrode

    A high-performance electrochromic-energy storage device (EESD) is developed, which successfully realizes the multifunctional combination of electrochromism and energy storage by constructing tungsten trioxide monohydrate (WO 3 ·H 2 O) nanosheets and Prussian white (PW) film as asymmetric electrodes. The EESD presents excellent electrochromic properties of broad optical modulation (61.7%), ultrafast response speed (1.84/1.95 s), and great coloration efficiency (139.4 cm 2 C -1 ). In particular, remarkable cyclic stability (sustaining 82.5% of its initial optical modulation after 2500 cycles as an electrochromic device, almost fully maintaining its capacitance after 1000 cycles as an energy storage device) is achieved. The EESD is also able to visually detect the energy storage level via reversible and fast color changes. Moreover, the EESD can be combined with commercial solar cells to constitute an intelligent operating system in the architectures, which would realize the adjustment of indoor sunlight and the improvement of physical comfort totally by the rational utilization of solar energy without additional electricity. Besides, a scaled-up EESD (10 × 11 cm 2 ) is further fabricated as a prototype. Such promising EESD shows huge potential in practically serving as electrochromic smart windows and energy storage devices.

    Radioactive cesium pollution have received considerable attention due to the increasing risks in development of the nuclear power plants in the world. Although various functional porous materials are utilized to adsorb Cs+ ions in water, Prussian blue analogues (PBAs) are an impressive class of candidates because of their super affinity of Cs+ ions. The adsorption ability of the PBAs strongly relate to the mesostructure and interstitial sites. To design a hollow PBA with large number of interstitial sites, the traditional hollowing methods are not suitable owing to the difficulty in processing the specific PBAs with large number of interstitial sites. In this work, we empolyed a rational strategy which was to form a "metal oxide"@"PBA" core-shell structure via coordination replication at first, then utilized a mild etching to remove the metal oxide core, led to hollow PBA finally. The obtained hollow PBAs were of high crystallinity and large number of interstitial sites, showing a super adsorption performance for Cs+ ions (221.6 mg/g) within a short period (10 min).

  18. Amperometric immunosensor based on multiwalled carbon nanotubes/Prussian blue/nanogold-modified electrode for determination of α-fetoprotein.

    2010-12-01

    In this article, a conspicuously simple and highly sensitive amperometric immunosensor based on the sequential electrodeposition of Prussian blue (PB) and gold nanoparticles (GNPs) on multiwalled carbon nanotube (MWCNT)-modified glassy carbon electrode (GCE) surface is proposed for the detection of α-fetoprotein (AFP). By comparison with PB, the MWCNT/PB composite film had been proven to show much better electrochemical stability and a larger response current. The electrodeposited GNP film can be used not only to immobilize biomolecules but also to avoid the leakage of PB and to prevent shedding of MWCNT/PB composite film from the electrode surface. The performance and factors influencing the performance of the immunosensor were investigated. Under optimal experimental conditions, the proposed immunosensor for AFP was observed with an ultralow limit of detection (LOD) equal to 3 pg/ml (at 3δ), and the linear working range spanned the concentrations of AFP from 0.01 to 300 ng/ml. Moreover, the immunosensor, as well as a commercially available kit, was examined for use in the determination of AFP in real human serum specimens. More significant, the assay mentioned here is simpler than the traditional enzyme-linked immunosorbent assay (ELISA), and an excellent correlation of levels of AFP measured was obtained, indicating that the developed immunoassay could be a promising alternative approach for detection of AFP and other tumor markers in the clinical diagnosis.

    Keihan, A.H.; Sajjadi, S.

    2013-01-01

    This paper reports the greatly improved electrochemical properties of Prussian blue/carbon nanotubes (PB/CNTs) modified glassy carbon electrode via a room temperature ionic liquid (RTIL) treatment. Firstly, the GC electrodes were modified with nanocomposites of RTIL/CNTs. Then, the PB nanoparticles were electrodeposited onto the modified electrode surface. Compared with the PB/CNTs/GC, the PB/RTIL/CNTs/GC electrodes showed higher PB surface concentration value of 2.42 × 10 −9 mol cm −2 , indicating that PB deposition efficiency was improved by 1.8 fold. The apparent diffusion coefficient for K + displayed value of 5.77 × 10 −11 cm 2 s −1 , which was one order of magnitude higher than that in the absence of RTIL. PB/RTIL/CNTs/GC modified electrodes showed higher electron transfer rate of 2.44 s −1 (2.35 times as much as that of PB/CNTs/GC electrodes). RTIL modified electrodes also displayed high sensitivity toward H 2 O 2 reduction (185.90 μA mM −1 cm −2 ) with low detection limit of 0.49 μM. The RTIL modified electrodes stored dry at room temperature preserved almost 100% of their initial currents over a period of 1 month, a useful property for commercial applications

    Full Text Available A regular nanostructure has been widely confirmed to result ina marked improvement in material performance in biosensing applications. In the present study, a regular nanostructured Prussian blue (PB film with two heterogeneous crystal layers was synthesized in-situ using a secondary growth method. A PB seed layer was first controlled to form uniform cube-like crystal nuclei through an ultrasonic reaction with a single reactant. Then, well-defined 100 nm PB nanocubes were further crystallized on this seed layer using a self-assembly approach. In order to accelerate the electron transfer rate during the enzyme reaction for glucose detection, the graphene was used as the main cross-linker to immobilize glucose oxidase on the PB film. The as-prepared biosensor exhibited high electrocatalysis and electron conductivity for the detection of trace glucose with a sensitivity of 141.5 μA mM−1 cm−2, as well as excellent anti-interference ability in the presence of ascorbic acid and uric acid under a low operation potential of −0.05 V.

    Thapa, Shyam

    2004-11-01

    In 2002 Nepal's parliament passed a liberal abortion law, after nearly three decades of reform efforts. This paper reviews the history of the movement for reform and the combination of factors that contributed to its success. These include sustained advocacy for reform; the dissemination of knowledge, information and evidence; adoption of the reform agenda by the public sector and its leadership in involving other stakeholders; the existence of work for safe motherhood as the context in which the initiative could gain support; an active women's rights movement and support from international and multilateral organisations; sustained involvement of local NGOs, civil society and professional organisations; the involvement of journalists and the media; the absence of significant opposition; courageous government officials and an enabling democratic political system. The overriding rationale for reforming the abortion law in Nepal has been to ensure safe motherhood and women's rights. The first government abortion services officially began in March 2004 at the Maternity Hospital in Kathmandu; services will be expanded gradually to other public and private hospitals and private clinics in the coming years.

    2017-09-01

    Full Text Available The international comparison and competitive focus on (academic performance, together with the growing awareness that early years impact children’s learning and development in education as well as over a lifetime, has resulted in heightened political interest in the learning of the youngest children. Politicians take action to achieve what they assume to be most effective approach, resulting in more centralized control, and more structured learning approaches introduced to children at still younger ages (Brogaard-Clausen, 2015: Brehony, 2000: Moss, 2013. In the Nordic countries1 there is a general concern for early years and the challenges facing early childhood education and care in an era of increasing globalization, with focus on accountability and academic competition (Ringsmose, Kragh-Müller, 2017. In Denmark, the social pedagogical tradition has been part of the culture of early childhood education for decades. In the social pedagogical tradition, relationships, play, and children’s influence are considered of key importance, and as the child’s natural way to learn about, and make sense of the world. It is considered that children learn and explore through play and participation embedded in the culture. Recently, the ministry of education has discussed more focused learning plans, and has tried out a program with more structured learning approaches. The gradual changes, together with the possible political action, are changes seriously threatening the social pedagogical tradition with more school-like, and more structured ways for children to interact. The purpose of this article is to present the Danish example as an alternative to the schoolification of early years that we see in many countries.

    Full Text Available In this paper, we review the past two decades of administrative reform in South Korea and argue that the dominant models and theories in the fi eld, i.e., New Public Management (NPM, post-NPM, and traditional public administration have been in a state of fusion in implementing measures without a coherent reform model. We observe that the reform movements can neither challenge nor undermine the traditional bureaucracy and maintain that they are the result of a complex mix of both environmental events and contextual factors. We specifi cally examine the co ncrete change and development of administrative reform during the Kim Dae Jung (1998- 2003, Roh Moo Hyun (2003-2008, and Lee Myung Bak (2008-2013 administrations in South Korea. Among the cases being considered are the restructuring of government ministries, the executive agency system, and rationalization of public enterprises, as well as such performance management schemes as the evaluation system for government departments and the Open Position System. We conclude that the developmental state and the hierarchical bureaucracy are still salient in South Korea’s inconsistent administrative reform since the 1990s and that it is crucial to design a prudent reform strategy to achieve a more effective public sector.

  2. Health Care Reform: a Socialist Vision

    Directory of Open Access Journals (Sweden)

    2010-04-01

    Full Text Available At first glance, it doesn't seem as though socialism and health-care reform have a whole lot to do with each other. After all, the most visible "left" position in the current discussion of health-care reform merely advocates for the government to assume the function of national insurer, leaving the delivery of health care - from its often-questionable content to its hierarchical relationships - firmly in place. As such, a single payer, Medicare-for-All insurance program is a modest, even tepid reform. Those of us on the left who have been active in the single payer movement have always seen it as a steppingstone toward health-care justice: until the question of access to care is solved, how do we even begin to address not only health care but also health inequities? How, for example, can working-class Americans, Americans of color, and women demand appropriate, respectful, humane, first-rate care when our ability to access any health-care services at all is so tightly constrained?

  4. The 'reformation' of counselling

    Full Text Available Although the Reformation took place some four hundred years ago, one area in which reformation is really needed today is the counselling of people. Since Wilhelm Wundt started the “study of the mind” in 1879, William James and Sigmund Freud followed and secular psychology gradually has developed to take the “front seat”; hence moving Biblical counselling, which has been practised since the times of the New Testament, to the “back burner”. This development had been going on for the greater part of the 20th century, up to the publication of Competent to Counsel by Jay E. Adams in 1970. In the model for counselling suggested by Adams, the principles of the Reformation of the sixteenth century, Soli Deo Gloria, Soli Scriptura, Soli Fidei, Sola Gratia, etc. were again implemented in assisting and counselling people with personal and interpersonal problems. The epistomological and anthropological approach of secular psychology differs radically from that of Biblical principles, thus necessitating a new “reformation” of counselling. Within this new form counselling, inter alia, implies the following: the Word of God has its rightful place, sin has to be taken seriously and the work of the Holy Spirit should be recognised. In this article it is proposed that the “reformation” of counselling was started by scholars with a Biblical Reformational approach and that this method of counselling followed the parameters of the Reformation of the sixteenth century. This “reformation” developed into a new direction in counselling and still continues today with fascinating new frontiers opening up for Biblical counselling.

  6. Voltammetric determination of paracetamole using a glassy carbon electrode modified with Prussian Blue and a molecularly imprinted polymer, and ratiometric read-out of two signals

    The authors report on a ratiometric electrochemical sensor for paracetamole (PR) which was fabricated by successively electropolymerizing a layer of Prussian blue (PB) and a layer of molecularly imprinted polypyrrole (MIP) on the surface of a glassy carbon electrode (GCE). The binding of PR molecules to the MIP has two effects: The first is an increase of the oxidation current for PR at 0.42 V (vs. SCE), and the second is a decrease in the current for PB (at 0.18 V) due to partial blocking of the channels which results in reduced electron transmissivity. Both currents, and in particular their ratio, can serve as analytical information. Under optimized conditions, the sensor displays enhanced sensitivity for PR in the 1.0 nM to 0.1 mM concentration range and a 0.53 nM lower limit of detection. The sensor was applied to the determination of PR in tablets and urines where it gave recoveries in the range between 94.6 and 104.9 %. This dual-signal (ratiometric) detection scheme (using electro polymerized Prussian Blue and analyte-specific MIP) in our perception has a wide scope in that it may be applied to numerous other electro active species for which specific MIP can be made available.

    High-flux synchrotron techniques allow microspectroscopic analyses of artworks that were not feasible even a few years ago, allowing for a more detailed characterization of their constituent materials and a better understanding of their chemistry. However, interaction between high-flux photons and matter at the sub-microscale can generate damages which are not visually detectable. We show here different methodologies allowing to evidence the damages induced by microscopic X-ray absorption near-edge structure spectroscopy analysis (μXANES) at the Fe and Zn K-edges of a painting dating from the turn of the twentieth century containing Prussian blue and zinc white. No significant degradation of the pigments was noticed, in agreement with the excellent condition of the painting. However, synchrotron radiation damages occurred at several levels, from chemical changes of the binder, modification of crystal defects in zinc oxide, to Prussian blue photoreduction. They could be identified by using both the μXANES signal during analysis and with photoluminescence imaging in the deep ultraviolet and visible ranges after analysis. We show that recording accurately damaged areas is a key step to prevent misinterpretation of results during future re-examination of the sample. We conclude by proposing good practices that could help in integrating radiation damage avoidance into the analytical pathway. (orig.)

  8. A Choline Oxidase Amperometric Bioassay for the Detection of Mustard Agents Based on Screen-Printed Electrodes Modified with Prussian Blue Nanoparticles

    Directory of Open Access Journals (Sweden)

    Fabiana Arduini

    2015-02-01

    Full Text Available In this work a novel bioassay for mustard agent detection was proposed. The bioassay is based on the capability of these compounds to inhibit the enzyme choline oxidase. The enzymatic activity, which is correlated to the mustard agents, was electrochemically monitored measuring the enzymatic product, hydrogen peroxide, by means of a screen-printed electrode modified with Prussian Blue nanoparticles. Prussian Blue nanoparticles are able to electrocatalyse the hydrogen peroxide concentration reduction at low applied potential (−50 mV vs. Ag/AgCl, thus allowing the detection of the mustard agents with no electrochemical interferences. The suitability of this novel bioassay was tested with the nitrogen mustard simulant bis(2-chloroethylamine and the sulfur mustard simulants 2-chloroethyl ethyl sulfide and 2-chloroethyl phenyl sulfide. The bioassay proposed in this work allowed the detection of mustard agent simulants with good sensitivity and fast response, which are excellent premises for the development of a miniaturised sensor well suited for an alarm system in case of terrorist attacks.

    Highlights: ► Novel process for the synthesis of PBNPs sol of 15.8 nm size is reported. ► The PBNPs sol shows the electron transfer rate constant to the order of 32.1 s −1 ► The PBNPs sol has shown the functional activity for making the nanocomposite. ► The nanocomposite with tris(2,2′-bipyridyl)ruthenium shows photoluminiscent ability. ► The PBNPs and its nanocomposite (PB-Rubpy) show high sensitivity for H 2 O 2 sensing. - Abstract: This paper reports a new method for the synthesis of Prussian blue nanoparticles (PBNPs) sol of homogeneous dispersion with average particle size to the order of 15.8 nm. The new method of PBNPs sol synthesis is based on the interaction of active concentrations of 3-aminopropylalkoxysilane, cyclohexanone and single precursor potassium ferricyanide under ambient conditions. The PBNPs sol shows excellent electrochemistry with electron transfer rate constant to the order of 32.1 s −1 . The resulting PBNPs sol has been found highly stable for practical applications and shows functional activity for making nanocomposite sol with tris(2,2′-bipyridyl) ruthenium (Rubpy). The PB-Rubpy nanocomposite shows high sensitivity for H 2 O 2 electrochemical sensing to the order of 1102.0 μA mM −1 cm −2 and storage stability of the materials for more than 3 months. In addition, these nanocomposite exhibits excellent electrocatalytic property for hydrogen peroxide (H 2 O 2 ) sensing with catalytic rate constant to the order of 3.14 × 10 3 M −1 s −1 . The PB-Rubpy nanocomposite sol, apart from electrocatalytic application, shows photoluminiscent ability for many opto-electroanalytical applications. In addition to that functional property of PBNPs sol for making nanodispersion with several known nanoparticles of gold, silver, palladium along with in situ synthesis of mixed metal hexacyanoferrate have also been observed.

  10. A solid-state hybrid density functional theory study of Prussian blue analogues and related chlorides at pressure

    The variations with pressure in the structural, electronic and magnetic properties of a series of Prussian blue analogues (PBAs) K{sup I}M{sup II}[Cr{sup III}(CN){sub 6}] (M = V{sup II}, Mn{sup II} and Ni{sup II}) and associated isomorphous chlorides K{sup I}M{sup II}Cr{sup III}Cl{sub 6} are investigated within a series of solid-state hybrid density functional calculations. The sensitivity of the computed properties to the choice of Hamiltonian is tested by application of functionals containing 35%, 65% and 100% admixtures of Fock exchange. Magnetic coupling constants (J) are obtained at a range of cell volumes (V), with fits of the Bloch relationship (J {proportional_to} V{sup -{epsilon}}, {epsilon} typically 3-4) yielding exponents {epsilon} in the ranges 5.16-6.34, 8.48-12.07 and 4.00-4.51 for the antiferromagnetic (AF) V{sup II}Cr{sup III}-, ferrimagnetic (FI) Mn{sup II}Cr{sup III}- and ferromagnetic (FO) Ni{sup II}Cr{sup III} PBAs, respectively; and 3.33-4.99, 1.86-3.09 and 1.65-3.28 for the AF V{sup II}Cr{sup III}-, FO Mn{sup II}Cr{sup III}- and FO Ni{sup II}Cr{sup III} chlorides, respectively. The Mn{sup II}Cr{sup III} PBA range encloses the high values {epsilon}{approx}9-10 obtained in a recent joint experimental and theoretical study, and it is suggested that this strong magnetostructural effect arises due to the presence of competing AF and FO interactions in this material. Estimates of the spin ordering temperatures derived from the combination of the 35%-functional couplings with a mean field approach are in good agreement with experiment in the V{sup II}Cr{sup III} and Ni{sup II}Cr{sup III} PBAs, but are too low in the Mn{sup II}Cr{sup III} system. The variations with pressure in the structural parameters, charges and spin moments are also detailed, the PBA and chloride energy-volume data yielding bulk moduli in the ranges 39-53 and 36-50 GPa, respectively. Finally, the energies governing CN{sup -} ligand isomerization are estimated and successfully

    A naphta fraction is subjected to a catalytic reforming process in several series-connected reactors. The first reactor is equipped with a moving catalyst bed containing not more the 30% of volume of the total catalyst amount. The other reactors are designed as packed-bed systems. The content of coke deposited on the catalyst of the first reactor owing to the reforming process is maintained at below 1% of weight. This is effected by periodic removal of a proportion of the contaminated catalyst from the bottom part of the bed, by its regeneration and re-feeding to the top part of the bed. This results in prolonged service life of the catalyst and simultaneous improvement of the anti-knock value of the product.

  18. Evolution of the antipsychiatry movement into mental health consumerism.

    Science.gov (United States)

    Rissmiller, David J; Rissmiller, Joshua H

    2006-06-01

    This essay reviews the history and evolution of the antipsychiatry movement. Radical antipsychiatry over several decades has changed from an antiestablishment campus-based movement to a patient-based consumerist movement. The antecedents of the movement are traced to a crisis in self-conception between biological and psychoanalytic psychiatry occurring during a decade characterized by other radical movements. It was promoted through the efforts of its four seminal thinkers: Michel Foucault in France, R. D. Laing in Great Britain, Thomas Szasz in the United States, and Franco Basaglia in Italy. They championed the concept that personal reality and freedom were independent of any definition of normalcy that organized psychiatry tried to impose. The original antipsychiatry movement made major contributions but also had significant weaknesses that ultimately undermined it. Today, antipsychiatry adherents have a broader base and no longer focus on dismantling organized psychiatry but look to promote radical consumerist reform.

  1. Adequacy, accountability, autonomy and equity in a Middle Eastern school reform: The case of Qatar

    Science.gov (United States)

    Guarino, Cassandra M.; Tanner, Jeffery C.

    2012-04-01

    This study examines Qatar's recent and ambitious school reform in the early stages of its implementation against a set of four criteria for successful education systems drawn from guidelines developed by the international community: adequacy, accountability, autonomy and gender equity. We investigate both the initial structure of the reform and its sustainability in light of concerns that movements in these directions might be politically unfeasible. To some degree, these concerns are substantiated by the developments we trace. However, it is important to note that the reform has changed the landscape of primary and secondary education in Qatar and that many reform principles, though diluted, have been retained. This paper highlights lessons learned - both hopeful and cautionary - in the first few years of reform and presents a methodology for evaluating progress along key dimensions that can be applied to school systems in many nations.

    A steam reformer is disclosed having an annular steam reforming catalyst bed formed by concentric cylinders and having a catalytic combustor located at the center of the innermost cylinder. Fuel is fed into the interior of the catalytic combustor and air is directed at the top of the combustor, creating a catalytic reaction which provides sufficient heat so as to maintain the catalytic reaction in the steam reforming catalyst bed. Alternatively, air is fed into the interior of the catalytic combustor and a fuel mixture is directed at the top. The catalytic combustor provides enhanced radiant and convective heat transfer to the reformer catalyst bed.

    Turkish electricity reform has progressed slowly due to internal resistance against privatisation, and gained momentum after Electricity Market Law of 2001, prepared in line with EU Energy Acquis and established required institutional and legal framework. Although the eligibility threshold has reached 39% market opening rate, the dominant position of public both as owner and decision-maker is still the major problem in the sector. Currently Turkey is self-sufficient in electricity, but likely to face shortages in 10 years if the growing demand is not met by either speeding the liberalisation process, or joining the South East Europe Electricity Market.

    Aqueous phase reforming is useful for processing oxygenated hydrocarbons to hydrogen and other more useful products. Current processing is hampered by the fact that oxide based catalysts are not stable under high temperature hydrothermal conditions. Silica in the form of structured MCM-41 is thermally a more stable support for Co and Ni than conventional high surface area amorphous silica but hydrothermal stability is not demonstrated. Carbon nanotube supports, in contrast, are highly stable under hydrothermal reaction conditions. In this project we show that carbon nanotubes are stable high activity/selectivity supports for the conversion of ethylene glycol to hydrogen.

    The purpose of this study is to assess the long-term stability of Prussian blue (PB) drug product (DP) and active pharmaceutical ingredient (API) under laboratory storage conditions by monitoring the loss in water content and the corresponding change of the in vitro thallium binding capacity that represents product performance. The bound water content and the in vitro thallium binding capacity of PB DPs and APIs were measured in 2003 and 2013, respectively. Water content, a critical quality attribute that directly correlates to the thallium (Tl) binding capacity was measured by thermal gravimetric analysis (TGA). The thallium binding study was conducted by testing PB in buffered solutions over the human gastrointestinal pH range with thallium concentrations ranging from 600 to 1,500 ppm. Samples were incubated at physiological temperature of 37°C in a shaking water bath to mimic gastric flux and intestinal transport. The binding equilibrium was reached at 24h. Following incubation, each sample was filtered and the free thallium was analyzed using a validated inductively coupled plasma spectroscopic method (ICP). The Langmuir isotherm was plotted to calculate maximum binding capacity (MBC). Compared with 2003, the water content of DP-1 decreased by about 14.1% (from 15.6 to 13.4 mol), and the MBC of DP-1 decreased by about 12.5% (from 714 to 625 mg/g) at pH 7.5. When low concentration of thallium (600 ppm) was used at pH 7.5, the Tl binding remained comparable for both API-1 (286 vs 276 mg/g) and DP-1 (286 vs 268 mg/g). Similarly, the Tl binding remained unchanged for both API-1 (237 vs 255 mg/g) and DP-1 (234 vs 236 mg/g) at pH 5.0. However, at pH 1.0 the binding was reduced 32.3% and 25.9% for API-1 and DP-1, respectively. Since the majority of binding takes place in the upper GI tract where pH around 5 can be expected, and therefore, the Tl binding capacity of PB should be comparable for new and aged samples. The findings that Tl binding changes with the water

    Efficient water splitting demands highly active, low cost, and robust electrocatalysts. In this study, we report the synthesis of penroseite (Ni,Co)Se2 nanocages anchored on 3D graphene aerogel using Prussian blue analogues as precursor and further their applications in overall water splitting electrolysis. The synergy between the high activity of (Ni,Co)Se2 and the good conductivity of graphene leads to superior performance of the hybrid toward the water splitting in basic solutions. The (Ni,Co)Se2-GA only requires a low cell voltage of 1.60 V to reach the current density of 10 mA cm-2, making the (Ni,Co)Se2-GA hybrid a competitive alternative to noble metal based catalysts for water splitting.

    Prussian blue (PB) is limited in its application by its breakdown at elevated temperatures. To improve the heat resistance of PB, we prepared a composite film comprising PB nanoparticles (NPs), smectite clay, and an organic compound. The composite film had a microstructure in which PB NPs were intercalated between smectite/organic compound layers. The predominant oxidation temperature of the PB NPs in the composite film was around 500 °C in air, higher than the oxidation temperature of bulk PB in air (250 °C). This improvement in the oxidation temperature may be due to the composite film acting as a barrier to oxygen gas. These results indicate the effectiveness of clay materials for the improvement of heat resistance for low-temperature decomposition compounds, not only PB but also other porous coordination polymers.

    We have explored interfacial electrochemical electron transfer (ET) and electrocatalysis of 5–6 nm Prussian Blue nanoparticles (PBNPs) immobilized on Au(111)-electrode surfaces via molecular wiring with variable-length, and differently functionalized thiol-based self-assembled molecular monolayers...... (SAMs). The SAMs contain positively (−NH3+) or negatively charged (–COO–) terminal group, as well an electrostatically neutral hydrophobic terminal group (–CH3). The surface microscopic structures of the immobilized PBNPs were characterized by high-resolution atomic force microscopy (AFM) directly...... in aqueous electrolyte solution under the same conditions as for electrochemical measurements. The PBNPs displayed fast and reversible interfacial ET on all the surfaces, notably in multi-ET steps as reflected in narrow voltammetric peaks. The ET kinetics can be controlled by adjusting the length of the SAM...

  15. Small School Reform

    2013-05-01

    Full Text Available This qualitative ethnographic case study explored the evolution of a public urban high school in its 3rd year of small school reform. The study focused on how the high school proceeded from its initial concept, moving to a small school program, and emerging as a new small high school. Data collection included interviews, observations, and document review to develop a case study of one small high school sharing a multiplex building. The first key finding, “Too Many Pieces, Not Enough Glue,” revealed that the school had too many new programs starting at once and they lacked a clear understanding of their concept and vision for their new small school, training on the Montessori philosophies, teaching and learning in small schools, and how to operate within a teacher-cooperative model. The second key finding, “A Continuous Struggle,” revealed that the shared building space presented problems for teachers and students. District policies remain unchanged, resulting in staff and students resorting to activist approaches to get things done. These findings offer small school reform leaders suggestions for developing and sustaining a small school culture and cohesion despite the pressures to revert back to top-down, comprehensive high school norms.

  16. Ecological tax reform

    International Nuclear Information System (INIS)

    1996-01-01

    An environmental tax reform is seen by many as a possible solution to some crucial problems of modern society - pollution, excessive resource consumption and unemployment. Changes in the system of taxation are here seen as a long term process, one that must cheapen the costs of labour and make the costs of resource use more expensive - a process which can also create major changes in our society as to conceptions of quality, work, consumption etc. The conference presented proposals for an ecological tax and duty system that would contribute to: Changing technology so that it becomes more resource and energy effective. Changing the economic mechanisms so that resource consumption and pollution become more expensive while human resources become cheaper. Changing personal life styles and values so that material consumption becomes less decisive for our choices and priorities. An environmental tax reform is neither without problems nor painless. An economy and an industrial sector based on increasing consumption of energy and raw materials will, in the long run, lead to drawbacks that far outweigh those that are connected with an economic re-orientation whose driving force is another conception of nature.

  18. Pension Reform in China.

    Science.gov (United States)

    Liu, Tao; Sun, Li

    2016-01-01

    This article analyzes China's pension arrangement and notes that China has recently established a universal non-contributory pension plan covering urban non-employed workers and all rural residents, combined with the pension plan covering urban employees already in place. Further, in the latest reform, China has discontinued the special pension plan for civil servants and integrated this privileged welfare class into the urban old-age pension insurance program. With these steps, China has achieved a degree of universalism and integration of its pension arrangement unprecedented in the non-Western world. Despite this radical pension transformation strategy, we argue that the current Chinese pension arrangement represents a case of "incomplete" universalism. First, its benefit level is low. Moreover, the benefit level varies from region to region. Finally, universalism in rural China has been undermined due to the existence of the "policy bundle." Additionally, we argue that the 2015 pension reform has created a situation in which the stratification of Chinese pension arrangements has been "flattened," even though it remains stratified to some extent.

  20. Common morality and moral reform.

    Science.gov (United States)

    Wallace, K A

    2009-01-01

    The idea of moral reform requires that morality be more than a description of what people do value, for there has to be some measure against which to assess progress. Otherwise, any change is not reform, but simply difference. Therefore, I discuss moral reform in relation to two prescriptive approaches to common morality, which I distinguish as the foundational and the pragmatic. A foundational approach to common morality (e.g., Bernard Gert's) suggests that there is no reform of morality, but of beliefs, values, customs, and practices so as to conform with an unchanging, foundational morality. If, however, there were revision in its foundation (e.g., in rationality), then reform in morality itself would be possible. On a pragmatic view, on the other hand, common morality is relative to human flourishing, and its justification consists in its effectiveness in promoting flourishing. Morality is dependent on what in fact does promote human flourishing and therefore, could be reformed. However, a pragmatic approach, which appears more open to the possibility of moral reform, would need a more robust account of norms by which reform is measured.

    2018-01-15

    Herein, a resettable and reprogrammable biomolecular keypad lock on the basis of a closed bipolar electrode (BPE) system was established. In this system, one ITO electrode with immobilized chitosan (CS) and glucose oxidase (GOD), designated as CS-GOD, acted as one pole of BPE in the sensing cell; another ITO with electrodeposited Prussian blue (PB) films as the other pole in the reporting cell. The addition of ascorbic acid (AA) in the sensing cell with driving voltage (V tot ) at +2.5V would make the PB films become Prussian white (PW) in the reporting cell, accompanied by the color change from blue to nearly transparent. On the other hand, with the help of oxygen, the addition of glucose in the sensing cell with V tot at -1.5V would induce PW back to PB. The change of color and the corresponding UV-vis absorbance at 700nm for the PB/PW films in the reporting cell could be reversibly switched by changing the solute in the sensing cell between AA and glucose and then switching V tot between +2.5 and -1.5V. Based on these, a keypad lock was developed with AA, glucose and V tot as 3 inputs, and the color change of the PB/PW films as the output. This keypad lock system combined enzymatic catalysis with bipolar electrochemistry, demonstrating some unique advantages such as good reprogrammability, easy resettability and visual readout by naked eye.

  11. Independence of Movement Preparation and Movement Initiation.

    Science.gov (United States)

    Haith, Adrian M; Pakpoor, Jina; Krakauer, John W

    2016-03-09

    Initiating a movement in response to a visual stimulus takes significantly longer than might be expected on the basis of neural transmission delays, but it is unclear why. In a visually guided reaching task, we forced human participants to move at lower-than-normal reaction times to test whether normal reaction times are strictly necessary for accurate movement. We found that participants were, in fact, capable of moving accurately ∼80 ms earlier than their reaction times would suggest. Reaction times thus include a seemingly unnecessary delay that accounts for approximately one-third of their duration. Close examination of participants' behavior in conventional reaction-time conditions revealed that they generated occasional, spontaneous errors in trials in which their reaction time was unusually short. The pattern of these errors could be well accounted for by a simple model in which the timing of movement initiation is independent of the timing of movement preparation. This independence provides an explanation for why reaction times are usually so sluggish: delaying the mean time of movement initiation relative to preparation reduces the risk that a movement will be initiated before it has been appropriately prepared. Our results suggest that preparation and initiation of movement are mechanistically independent and may have a distinct neural basis. The results also demonstrate that, even in strongly stimulus-driven tasks, presentation of a stimulus does not directly trigger a movement. Rather, the stimulus appears to trigger an internal decision whether to make a movement, reflecting a volitional rather than reactive mode of control.

  15. Radiant non-catalytic recuperative reformer

    Energy Technology Data Exchange (ETDEWEB)

    Khinkis, Mark J.; Kozlov, Aleksandr P.

    2017-10-31

    A radiant, non-catalytic recuperative reformer has a flue gas flow path for conducting hot exhaust gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is positioned adjacent to the flue gas flow path to permit heat transfer from the hot exhaust gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, a portion of the reforming mixture flow path is positioned outside of flue gas flow path for a relatively large residence time.

    Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form synthesis gas (syngas). Closed-loop reforming/methanation systems can be used for storage and transport of process heat and for short-term storage for peaking power generation. Open-loop systems can be used for direct fuel production; for production of syngas feedstock for further processing to specialty chemicals and plastics and bulk ammonia, hydrogen, and liquid fuels; and directly for industrial processes such as iron ore reduction. In addition, reforming of organic chemical wastes and hazardous materials can be accomplished using the high-efficiency destruction capabilities of steam reforming. To help identify the most promising areas for future development of this technology, we discuss in this paper the economics and market potential of these applications.

    Medeiros, Regianne Leila Rolim; Atkinson, Sarah

    2015-01-01

    The objective of this article is to offer an overview of the health reform in Ceará focusing on the decentralisation process in the 1990s. The driving factor behind the Brazilian health reform movement was the necessity to reorganise the national health system and overcome inequalities. For the reformists, decentralisation, and together with it the idea of popular participation, is seen as essential to guarantee the fulfilment of the people’s needs and to incorporate their voice in the decision-making processes of the health system. In the state of Ceará, after the 1986 elections, health reform movement members took control over the management of the state Health Secretariat. This is the main cause of the acceleration of the decentralisation process with the transference of responsibility over the management of health care delivery to municipalities. PMID:25729333

    The argument in favor of gradual - but sustained - financial reform is based on two factors. First, the development of borrower net worth will determine the health of the real and, ultimately, the financial sector. Thus, speeding up reforms when borrower net worth is subject to positive shocks - or slowing them when it is subject to negative shocks - appears sensible and appears to have worked better in practice. Second, the initial conditions of the banking sector - not just its net worth bu...

  10. Reforming health care in Hungary.

    Science.gov (United States)

    Császi, L; Kullberg, P

    1985-01-01

    Over the past two decades Hungary has initiated a series of social and economic reforms which have emphasized decentralization of control and the reintroduction of market mechanisms into the socialized economy. These reforms both reflect and reinforce a changing social structure, in particular the growing influence of upper class special interest groups. Market reforms are an expression of concurrent ideological shifts in Hungarian society. We examined the political significance of three recent proposals to reform health services against the backdrop of broader social and economic changes taking place. The first proposes a bureaucratic reorganization, the second, patient co-payments, and the third, a voucher system. The problems each proposal identifies, as well as the constituency each represents, reveal a trend toward consolidation of class structure in Hungary. Only one of these proposals has any potential to democratize the control and management of the heath care system. Moreover, despite a governmental push toward decentralization, two of these proposals would actually increase centralized bureaucratic control. Two of the reforms incorporate market logic into their arguments, an indication that the philosophical premises of capitalism are re-emerging as an important component of the Hungarian world-view. In Hungary, as well as in other countries, social analysis of proposed health care reforms can effectively illuminate the social and political dynamics of the larger society.

  11. Reforming the European Scene

    Directory of Open Access Journals (Sweden)

    Joseph Ezra Bigio

    2010-10-01

    Full Text Available An unbridled globalization based on a simple premise about earnings and profit may be detrimental to the livelihood of many thousands of individuals. The greed and utter selfishness that result from the adherence to this sort of business practice are the two things that generate more unemployment, misery and degradation than most other characteristics of the human species. These considerations present the challenge for Western societies and call for the implementation of other principles, standards and procedures, such as cooperation, cohesion, development objectives and social responsibility. In the first part of the paper this approach is tested in the case of the EU-US foreign exchange relationships. The second part of the paper raises more general and fundamental issues. While adhering to the Schumpeter-type innovation environment, it aims to introduce the social dimension ahead of the immediate competitiveness and, therefore, argues for the fundamental reform of the catechism of the capitalist manager. The EU, due to its advanced integration, is relatively well-equipped to move towards the new economic system.  

  12. Reforming the minimum wage: Toward a psychological perspective.

    Science.gov (United States)

    Smith, Laura

    2015-09-01

    The field of psychology has periodically used its professional and scholarly platform to encourage national policy reform that promotes the public interest. In this article, the movement to raise the federal minimum wage is presented as an issue meriting attention from the psychological profession. Psychological support for minimum wage reform derives from health disparities research that supports the causal linkages between poverty and diminished physical and emotional well-being. Furthermore, psychological scholarship relevant to the social exclusion of low-income people not only suggests additional benefits of financially inclusive policymaking, it also indicates some of the attitudinal barriers that could potentially hinder it. Although the national living wage debate obviously extends beyond psychological parameters, psychologists are well-positioned to evaluate and contribute to it.

    Encapsulation of [Fe(CN) 6 ] 4− and [Fe(CN) 6 ] 3− complexes in the intracrystalline pores of ZSM-5 zeolite, Fe II L/Z and Fe III L/Z respectively, by the zeolite synthesis method was reported. The modified zeolites were characterized by powder XRD, FT-IR and UV–vis spectroscopy. The nitrogen adsorption isotherms allow for the evaluation of pore structure of the complex-modified zeolites, whereas the thermal analysis (TGA/DTA) measurements provide insight into the decomposition products of the immobilized complexes. The modified zeolites exhibited smaller pore volumes and surface areas as compared with those of unpromoted ZSM-5, suggesting the inclusion of iron cyanides inside the interconnecting channels of ZSM-5. While the ferricyanide complex enhanced the formation of highly crystalline zeolite, the ferrocyanide one resulted in a lesser effect. The electronic spectra of the colloidal species developed when Fe III L/Z brought in contact with an aqueous solution of [Fe(CN) 6 ] 3− exhibit absorptions attributed to CN − → iron charge-transfer. New bands at 294 and 319 nm due to d–d transitions of Fe III tetrahedral monomeric moieties were emitted concurrently under successive adsorption of [Fe(CN) 6 ] aq 3− over Fe III L/Z, along with a broad band at 555 nm assigned to polymeric [Fe II –C–N–Fe III ] of Prussian blue (PB). The FT-IR spectra of Fe III/II L/Z devoted to the adsorption of an aqueous solution of [Fe(CN) 6 ] 3− showed a band at 2092 cm −1 assigned to the C–N stretch in the Fe II –CN–Fe III linkages. The vibrations attributable to Fe–O–Si bonding along with hydrocarbon and nitroprusside appeared only in the spectrum of Fe III L/Z, thus was found to be strong evidence for the mutual interaction between [Fe(CN) 6 ] 3− and the latter sample. - Highlights: • We synthesized ferrous and ferric cyanide complexes inside ZSM-5 zeolite. • The decomposition of the encapsulated complexes occurred at high temperatures.

The modified zeolites exhibited smaller pore volumes and surface areas as compared with those of unpromoted ZSM-5, suggesting the inclusion of iron cyanides inside the interconnecting channels of ZSM-5. While the ferricyanide complex enhanced the formation of highly crystalline zeolite, the ferrocyanide one resulted in a lesser effect. The electronic spectra of the colloidal species developed when Fe{sup III}L/Z brought in contact with an aqueous solution of [Fe(CN){sub 6}]{sup 3−} exhibit absorptions attributed to CN{sup −} → iron charge-transfer. New bands at 294 and 319 nm due to d–d transitions of Fe{sup III} tetrahedral monomeric moieties were emitted concurrently under successive adsorption of [Fe(CN){sub 6}]{sub aq}{sup 3−} over Fe{sup III}L/Z, along with a broad band at 555 nm assigned to polymeric [Fe{sup II}–C–N–Fe{sup III}] of Prussian blue (PB). The FT-IR spectra of Fe{sup III/II}L/Z devoted to the adsorption of an aqueous solution of [Fe(CN){sub 6}]{sup 3−} showed a band at 2092 cm{sup −1} assigned to the C–N stretch in the Fe{sup II}–CN–Fe{sup III} linkages. The vibrations attributable to Fe–O–Si bonding along with hydrocarbon and nitroprusside appeared only in the spectrum of Fe{sup III}L/Z, thus was found to be strong evidence for the mutual interaction between [Fe(CN){sub 6}]{sup 3−} and the latter sample. - Highlights: • We synthesized ferrous and ferric cyanide

    Highlights: • Systematic XANES measurements on Prussian blue analogs shows oxidation state of transition metals. • Cobal-iron bimetallic hexacyanometallates show unexpected oxidation states. • Iron(II) ions in hexacyanometallates(III) show varying spin state depending on their bond to the “N” end or “C” end of the cyanide ligand. • Thermal expansion coefficients have been linked to the XANES results. - Abstract: There have been renewed interests in metal-organic framework classes of materials such as Prussian blue analogues (PBAs) due to their potential usage in energy storage applications. In particular, due to their high surface areas, controllable structures and excellent electrochemical properties, PBAs such as hexacyanometalates M{sup II}{sub 3}[A{sup III}(CN){sub 6}]{sub 2*}nH{sub 2}O (M = Mn, Fe, Co, Ni, Cu, Zn; A = Co, Fe, Cr; n = no. of water molecules present), M{sup II}{sub 2}[Fe{sup II}(CN){sub 6}]{sub 2*}nH{sub 2}O (M = Mn, Co, Ni, Cu, Zn) and mixed hexacyanometalates(III) (Fe{sub 1-x}Co{sub x}){sub 3}[B{sup III}(CN){sub 6}]{sub 2}·nH{sub 2}O (x = 0.25, 0.5, 0.75; B = Co, Fe) could have possible usage as a new class of cathode and even anode materials for rechargeable batteries. Detailed knowledge of the oxidation states of the transition metals in PBAs is required to improve efficiency and durability of such devices. Furthermore, a link between the thermal expansion observed in these materials and the oxidation state of the transition metal is of interest to synthesize materials with a desired thermal expansion behavior, Here we demonstrate the use of Synchrotron based X-ray absorption near-edge structure (XANES) spectra to identify transition metal oxidation states. Our analysis reveals the presence of divalent, trivalent and/or mixed valence transition metals in the materials as well as high-spin and low-spin complexes.

    Compared with their higher-income counterparts, children growing up in low-income families in the United States typically complete less schooling, report worse health, and work and earn less in adulthood. Moreover, changes in the American economy over the last 40 years have raised the level of skills and qualifications that children need to obtain a good middle-class job, as well as making it much more difficult for children from low-income families to attend schools that support their learning of these skills. We first review strategies used in the past to improve K-12 schooling-including investing more money, introducing more accountability, and putting in place new governance structures (eg, charter schools)-and show why these strategies have been relatively ineffective. Drawing on the research literature and case studies, we then describe education reform strategies for prekindergarten programs and for elementary, middle, and high schools that may help meet these challenges. All of the initiatives described in our case studies provide ample opportunities for teachers and school leaders to improve their skills through coaching and other professional development activities; incorporate sensible systems of accountability, including requiring teachers to open their classrooms to the scrutiny of colleagues and school leaders and to work with their colleagues to improve their teaching practices; and incorporate high academic standards, such as those described in the Common Core State Standards. By focusing directly on improving teaching and promoting learning, these successful initiatives have boosted the achievement of low-income children. They show that it is indeed possible to make a real difference in the life chances of low-income children. Copyright © 2016 Academic Pediatric Association. Published by Elsevier Inc.

    Developing novel nanotheranostic agent using only clinically approved materials is highly desirable and challenging. In this study, we combined three clinically approved materials, Prussian blue (PB), serum albumin (BSA), and indocyanine green (ICG), by a simple and biocompatible method to prepare a multifunctional theranostic PB-BSA-ICG nanoparticle. The multifunctional nanoparticle system could provide dual mode magnetic resonance (MR) and near infrared (NIR) fluorescence imaging as well as combined photothermal and photodynamic (PTT-PDT) therapy in response to a single NIR laser. This nanoparticle showed an excellent stability in physiological solutions and could suppress the photo-instability of ICG. In the absence of light, the nanoparticles showed no cytotoxicity, but significant cell death was induced through combined PTT-PDT effect after irradiation with NIR laser light. A high tumor accumulation and minimal nonspecific uptake by other major organs of PB-BSA-ICG nanoparticle were observed in vivo, analyzed by T1-weighted MR and NIR fluorescence bimodal imaging in tumor xenograft mice after intravenous injection. The nanoparticles efficiently suppressed the tumor growth through combinatorial phototherapy with no tumor recurrence upon a single NIR laser irradiation. These results demonstrated that PB-BSA-ICG is potentially an interesting nanotheranostic agent for imaging guided cancer therapy by overcoming the limitations of each technology and enhancing the therapeutic efficiency as well as reducing side effects.

    2014-06-04

    In this work, poly(diallyldimethylammonium chloride) (PDDA) protected Prussian blue/gold nanoparticles/ionic liquid functionalized reduced graphene oxide (IL-rGO-Au-PDDA-PB) nanocomposite was fabricated. The resulting nanocomposite exhibited high biocompatibility, conductivity and catalytic activity. To assess the performance of the nanocomposite, a sensitive sandwich-type immunosensor was constructed for detecting alpha-fetoprotein (AFP). Greatly enhanced sensitivity for this immunosensor was based on triple signal amplification strategies. Firstly, IL-rGO modified electrode was used as biosensor platform to capture a large amount of antibody due to its increased surface area, thus amplifying the detection response. Secondly, a large number of Au-PDDA-PB was conjugated on the surface of IL-rGO, which meant the enrichment of the signal and the more immobilization of label antibody. Finally, the catalytic reaction between H2O2 and the IL-rGO-Au-PDDA-PB nanocomposite further enhanced the signal response. The signals increased linearly with AFP concentrations in the range of 0.01-100 ng mL(-1). The detection limit for AFP was 4.6 pg mL(-1). The immunosensor showed high sensitivity, excellent selectivity and good stability. Moreover, the immunosensor was applied to the analysis of AFP in serum sample with satisfactory result.

    A novel polypyrrole (PPy) and graphene quantum dots (GQDs) @ Prussian Blue (PB) nanocomposite has been grafted on a graphite felt (GF) substrate (PPy/GQDs@PB/GF), and has been proven to be an efficient electrochemical sensor for the determination of l-cysteine (l-cys). GQDs, which were fabricated by carbonization of citric acid and adsorbed on GF surface ultrasonically, played an important role for promoting the synthesis process of PB via a spontaneous redox reaction between Fe(3+) and [Fe(CN)6](3-). The PPy film has been electro-polymerized to improve the electrochemical stability of the PPy/GQDs@PB/GF electrode. The as-prepared electrode was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), infrared spectroscopy (IR), X-ray diffraction (XRD) and electrochemical methods. It exhibited an excellent activity for the electrocatalytic oxidation of l-cys, with a detection sensitivity equal to 0.41 Amol(-1) L for a concentration range of 0.2-50 μmolL(-1), and equal to 0.15 Amol(-1) L for a concentration range of 50-1000 μmolL(-1). A low detection limit of 0.15 μmolL(-1), as well as a remarkable long-time stability and a negligible sensitivity to interfering analytes, were also ascertained. Copyright © 2015 Elsevier B.V.

    Full Text Available Background. Prussian blue (PB, ferric hexacyanoferrate is approved by US-FDA for internal decorporation of Cesium-137 (137Cs and Thallium-201 (201Tl. Aim. Since PB is a costly drug, pH-dependent oral delivery system of PB was developed using calcium alginate matrix system. Methods. Alginate (Alg beads containing PB were optimized by gelation of sodium alginate with calcium ions and effect of varying polymer concentration on encapsulation efficiency and release profile was investigated. Scanning electron microscopy (SEM was carried out to study surface morphology. Adsorption efficacy of Alg-PB beads for 201Tl was evaluated and compared with native PB. In vivo pH-dependent release of the formulation was studied in humans using gamma scintigraphy. Results. Encapsulation efficiencies of Alg-PB beads with 0.5, 1.0, 1.5, and 2.0% polymer solution were 99.9, 91, 92, and 93%, respectively. SEM and particle size analysis revealed differences between formulations in their appearance and size distribution. No drug release was seen in acidic media (pH of 1-2 while complete release was observed at pH of 6.8. Dissolution data was fitted to various mathematical models and beads were found to follow Hixson-Crowell mechanism of release. The pH-dependent release of beads was confirmed in vivo by pharmacoscintigraphy in humans.

    Electrochemical performance of Prussian blue analogues (PBAs) as positive electrode materials for non-aqueous Na-ion batteries is known to be highly dependent on their synthesis conditions according to the previous researches. Na-rich PBAs, NaxM[Fe(CN)6]·nH2O where M = Mn, Fe, Co, and Ni, are prepared via precipitation method under the same condition. The structure, chemical composition, morphology, valence of the transition metals, and electrochemical property of these samples are comparatively researched. The PBA with Mn shows large reversible capacity of 126 mAh g-1 in 2.0-4.2 V at a current density of 30 mA g-1 and the highest working voltage owning to high redox potential of Mn2+/3+ in MnN6 and Fe2+/3+ in FeC6. While, the PBA with Ni exhibits the best cyclability and rate performance though only 66 mAh g-1 is delivered. The significant differences in electrochemical behaviors of the PBAs originate from the various properties depending on different transition metals.

    The large-scale fabrication of nanocomposite based biosensors is always a challenge in the technology commercialization from laboratory to industry. In order to address this issue, we have designed a facile chemical method of fabricated nanocomposite ink applied to the screen-printed biosensor chip. This ink can be derived in the water through the in-situ growth of Prussian blue nanocubes (PBNCs) on the silver nanowires (AgNWs) to construct a composite nanostructure by a facile chemical method. Then a miniature flexible biosensor chip was screen-printed by using the prepared nanocomposite ink. Due to the synergic effects of the large specific surface area, high conductivity and electrocatalytic activity from AgNWs and PBNCs, the as-prepared biosensor chip exhibited a fast response (biosensor chip exhibited excellent stability, good reproducibility and high anti-interference ability towards physiological substances under a very low working potential of -0.05. Hence, the proposed biosensor chip also showed a promising potential for the application in practical analysis. Copyright © 2016 Elsevier B.V. All rights reserved.

    The purpose of this article was to examine the work of Florence Nightingale in light of her collaboration with William Farr, the eminent medical statistician. Nightingale's epidemiological investigations supported by Farr illustrated that attention to environmental cleanliness was an important factor in preventing spread of disease. Nightingale channeled her investigations to support hospital reforms and the need for an educated nurse who could provide better management of the hospital environment. Statistical support and solicited criticism allowed Nightingale to argue more forcefully for her reforms.

  20. The practice of nature-study: What reformers imagined and what teachers did

    Science.gov (United States)

    Doris, Ellen Elizabeth

    The nature-study movement was an attempt to reform elementary education in America. It took place from about 1890 to 1930. Nature-Study, as envisioned by reformers, featured outdoor work and first-hand observation of common plants, animals and phenomenon. It stressed self expression and independent thinking. It also emphasized emotions and aesthetics, aiming to help children develop both knowledge of nature and an enduring love for it. Nature-study's advocates encouraged the expansion of school subject matter beyond the "three Rs." They also challenged the traditional pedagogy that revolved around rote memorization, recitation, and quiet classrooms. My investigation of the nature-study movement is focused on the practice of nature-study in schools. I first consider practice as it was imagined by reformers. I review the many specific suggestions they made, as well as more general statements about nature-study's aims, to learn what reformers hoped teachers would do. I then look at how nature-study was actually carried out. I use accounts written by teachers, children and observers, together with photographs, correspondence and reproductions of children's work to discover the range of ways in which nature-study materialized as teachers took up the subject with pupils. I also look closely at two particular versions of nature-study: one that developed in Chicago under the influence of Wilbur Jackman, and another that was promoted in New York State by faculty from Cornell's College of Agriculture. As a result of focusing in this way, I develop a detailed picture of what nature-study's advocates expected of teachers. I also describe what teachers, in specific instances, did. In addition, I offer some general conclusions about how nature-study was conceived of and carried out. I discuss how these conclusions relate to previous interpretations of the movement, and consider the relevance of the nature-study movement for contemporary educators, particularly those concerned

  1. The Brazilian electrical system reform

    International Nuclear Information System (INIS)

    Mendonca, A.F.; Dahl, C.

    1999-01-01

    Although the Brazilian electrical system has been a public monopoly, the threat of electricity shortages from a lack of investment triggered a comprehensive reform. In 1993 the government began a series of laws, decrees and regulations reforming the tariff policy, allowing privatization of utilities, foreign investments and independent power producers, and creating an independent transmission grid and a new electricity regulatory agency (ANEEL). The new regulatory framework is not completely defined but the proposed model intends to transform bulk electricity supply into a competitive market similar to that adopted in England. Our objective is to evaluate whether the proposed reform will succeed in attracting the required private capital, will allow an unregulated wholesale electricity market and will require a strict regulatory framework. The reform has been quite successful in privatizing the distribution companies but is allowing monopolistic rents, and has failed until now to attract private investments to expand generation capacity. The risk of blackouts has increased, and the proposed wholesale electricity market may not be appropriate because of barriers to constructing new hydroelectric units, now 90% of the system. Therefore, a new regulatory framework and a strong regulatory agency with a well-defined tariff policy should have preceded the privatization. (author)

    Historians have recognized that men with drinking problems were not simply the passive subjects of medical reform and urban social control in Gilded Age and Progressive Era America but also actively shaped the partial medicalization of habitual drunkenness. The role played by evangelical religion in constituting their agency and in the historical process of medicalization has not been adequately explored, however. A post-Civil War evangelical reform culture supported institutions that treated inebriates along voluntary, religious lines and lionized former drunkards who publicly promoted a spiritual cure for habitual drunkenness. This article documents the historical development and characteristic practices of this reform culture, the voluntarist treatment institutions associated with it, and the hostile reaction that developed among medical reformers who sought to treat intemperance as a disease called inebriety. Those physicians' attempts to promote therapeutic coercion for inebriates as medical orthodoxy and to deprive voluntarist institutions of public recognition failed, as did their efforts to characterize reformed drunkards who endorsed voluntary cures as suffering from delusions arising from their disease. Instead, evangelical traditions continued to empower reformed drunkards to publicize their own views on their malady which laid the groundwork for continued public interest in alcoholics' personal narratives in the twentieth century. Meanwhile, institutions that accommodated inebriates' voluntarist preferences proliferated after 1890, marginalizing the medical inebriety movement and its coercive therapeutics. © The Author 2013.

  10. Local court reforms and ‘global’ law

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available This study considers court reform programmes sponsored by the IMF and World Bank in Indonesia and Venezuela. It aims to broaden the frame of reference of ‘globalisation’ in law beyond the two traditional sites of human rights and trade. Drawing on a tradition of legal pluralism, it investigates the various sources of ‘global’ or universalising pressures on the law. The sources and impacts of these efforts may derive from and benefit or disadvantage specific groups in various locations. They will also promote or inhibit particular political, social or economic projects. The study concludes that various constituencies and impulses to reform refer to different versions of the ‘universal’ for their conception of right and legitimacy. These are neither inherently local nor unambiguously global. Local religious or egalitarian movements may refer to universal religious or political values just as interests in fair commercial dealing can call on international legal norms. In contrast to the local sites where law is performed, these universal sites exist in a multitude of indigenous, religious, political and legal imagined communities, each of which may be invoked in attempts to reform local practice.

  11. Reforming technology for syngas production

    1997-01-01

    Methane forming reactions using either steam or CO 2 have been known to industry for a long time. These endothermic reactions require the investment of a relatively large amount of energy. German researchers, in the 1970's, conceived and developed the idea to use this reaction and the reverse methanation reaction in a closed loop for the transportation and distribution of nuclear heat. The idea was also adopted for use with solar energy as a heat source. Utilizing solar energy as the heat source, the Weismann Institute of Science has fabricated, installed and operated a complete loop capable of the conversion and transportation of over 400 kW of heat. This system can be operated with a wide range of CO 2 /H 2 O/CH 4 feed mixtures. Steam reforming is the common reforming reaction in the ''open loop'' mode for the purpose of synthesis gas production. This is accomplished with a large excess of steam on a nickel catalyst. However, it has only recently been recognized that there is also a substantial market for CO 2 reforming. The CO 2 /CH 4 mixture in various proportions exists in many places and has, so far, not been used efficiently. The sources for this mixture are biogas produced in anaerobic digestion processes and gas resources such as the NATUNA gas field in Indonesia, and many others. Therefore, the system of CO 2 /CH 4 deserves more attention. Commercial catalysts used for steam reforming based on nickel are not suitable for this system. Therefore, other catalysts based on Rhodium and Ruthenium have been developed and some performance data is presented in this paper. Also presented is a conceptual schematic layout of a CO 2 reforming plant and matching methanator. A computer code for a detailed design of the entire loop in a commercial size system has been prepared where optimized operational conditions as well as equipment parameters can be determined.

    Full Text Available Islamic puritanism movements are the movements compelling to return to the teachings of Quran and Sunnah, as the pure teachings of Islam and abandon even abolish other teachings outside the teachings of Quran and Sunnah. The movements of Islamic puritanism can be considered as transnational movements because they spread their teachings and ideologies, create organizations, networks, and provide financial supports across nations. This paper describes Islamic puritanism movements in Indonesia and their transnational connections. Some Islamic puritanism movements in Indonesia can be considered as part of Islamic transnational movements, in which most of the movements are centered in the Middle East. In Indonesia, Islamic puritanism movements firstly appeared in the beginning of the nineteenth century, called Padri movement in West Sumatra. It was then continued to the emergence of Islamic organizations in the twentieth century. Recently, Islamic puritanism movements in Indonesia mostly take form as Salafism-Wahabism movements.

    Ireland’s long history of patriarchy is matched by the ongoing evolution of its women’s movements. Today’s complex, transnational feminism finds its precursor in the colonial era. The first wave of the Irish women’s movement dates from the mid-19th century, with the franchise secured for women in 1918 while still under British colonial rule. First-wave feminists played a role in the nationalist movement, but their demands were sidelined later, during the construction of a conserva...

    2015-02-15

    In this work, we presented a three-dimensional (3D) molecularly imprinted electrochemical sensor (MIECS) with novel strategy for ultrasensitive and specific quantification of metolcarb based on prussian blue (PB) mediated amplification combined with signal enhancement of ordered mesoporous carbon. The molecularly imprinted polymers were synthesized by electrochemically induced redox polymerization of para aminobenzoic acid (p-ABA) in the presence of template metolcarb. Ordered mesoporous carbon material (CMK-3) was introduced to enhance the electrochemical response by improving the structure of the modified electrodes and facilitating charge transfer processes of PB which was used as an inherent electrochemical active probe. The modification process for the working electrodes of the MIECS was characterized by scanning electron microscope (SEM) and cyclic voltammetry (CV), and several important parameters controlling the performance of the MIECS were investigated and optimized in detail. The MIECS with 3D structure had the advantages of ease of preparation, high porous surface structure, speedy response, ultrasensitivity, selectivity, reliable stability, good reproducibility and repeatability. Under the optimal conditions, the MIECS offered an excellent current response for metolcarb in the linear response range of 5.0 × 10(-10)-1.0 × 10(-4) mol L(-1) and the limit of detection (LOD) was calculated to be 9.3 × 10 (-11)mol L(-1) (S/N = 3). The proposed MIECS has been successfully applied for the determination of metolcarb in real samples with satisfactory recoveries. Furthermore, the construction route of this ultrasensitive 3D MIECS may provide a guideline for the determination of non-electroactive analytes in environmental control and food safety.

    We report here for the first time a comparison of the beneficial effects of different cationic surfactants - cetyl trimethyl ammonium bromide (CTAB), benzethonium chloride (BZT) and cetylpyridinium chloride (CPC) - for the electrochemical synthesis of Prussian Blue (PB) films, using cyclic voltammetry (CV), on screen-printed carbon electrodes (SPCEs). Their electrochemical properties were investigated, paying special attention to parameters such as the amount of PB deposited, film thickness, charge transfer rate, permeability, reversibility, stability and sensitivity to hydrogen peroxide detection. All surfactant-enhanced PB-modified SPCEs displayed a significant improvement in their electrochemical properties compared with PB-modified SPCEs formed in the absence of surfactants. Surfactant-modified electrodes displayed a consistently higher PB surface concentration value of 2.1±0.4×10(-8) mol cm(-2) (mean±SD, n=3) indicating that PB deposition efficiency was improved 2-3 fold. K(+) and Na(+) permeability properties of the films were also studied, as were kinetic parameters, such as the surface electron transfer rate constant (k(s)) and the transfer coefficient (α). The hydrogen peroxide sensitivity of surfactant-modified PB films generated by 10 electro-deposition CV cycles gave values of 0.63 A M(-1) cm(-2), which is higher than those reported previously for SPCEs by other authors. Finally, the first lactate microbiosensor described in the literature based on BZT-modified PB-coated carbon fiber electrodes is presented. Its very small cross-section (~10 μm diameter) makes it particularly suitable for neuroscience studies in vivo. Copyright © 2011 Elsevier B.V. All rights reserved.

    A novel electrochemical non-enzymatic hydrogen peroxide (H{sub 2}O{sub 2}) sensor has been developed based on Prussian blue (PB) and electrochemically reduced graphene oxide (ERGO). The GO was covalently modified on glassy carbon electrode (GCE), and utilized as a directing platform for in-situ synthesis of electroactive PB. Then the GO was electrochemically treated to reduction form to improve the effective surface area and electroactivity of the sensing interface. The fabrication process was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and atomic force microscopy (AFM). The results showed that the rich oxygen containing groups play a crucial role for the successful synthesis of PB, and the obtained PB layer on the covalently immobilized GO has good stability. Electrochemical sensing assay showed that the modified electrode had tremendous electrocatalytic property for the reduction of H{sub 2}O{sub 2}. The steady-state current response increased linearly with H{sub 2}O{sub 2} concentrations from 5 μM to 1 mM with a fast response time (less than 3 s). The detection limit was estimated to be 0.8 μM. When the sensor was applied for determination of H{sub 2}O{sub 2} released from living cells of macrophages, satisfactory results were achieved. - Highlights: • Covalent method was applied for immobilization of GO on glassy carbon electrode. • GO directed in-situ synthesis of electroactive PB. • PB-ERGO composite shows high electrocatalytic activity toward H{sub 2}O{sub 2}. • The modified biosensor is capable of detecting H{sub 2}O{sub 2} released from living macrophages.

    Electrochromic devices based on poly(3,4-ethylenedioxythiophene) (PEDOT) as the cathodic coloring electrode and polyaniline (PANI) or Prussian blue (PB) as the counter electrode containing a highly conductive, self-supporting, distensible and transparent polymer-gel electrolyte film encapsulating an ionic liquid, 1-butyl-1-methylpyrrolidiniumbis-(trifluoromethylsulfonyl)imide, have been fabricated. Polarization, charge transfer and diffusion processes control the electrochemistry of the functional electrodes during coloration and bleaching and these phenomena differ when PEDOT and PANI/PB were employed alternately as working electrodes. While the electrochemical impedance response shows good similitude for PEDOT and PANI electrodes, the responses of PEDOT and PB were significantly different in the PEDOT-PB device, especially during reduction of PB, wherein the overall amplitude of the impedance response is enormous. Large values of the coloration efficiency maxima of 281 cm2 C(-1) (lambda = 583 nm) and 274 cm2 C(-1) (lambda = 602 nm), achieved at -1.0 and -1.5 V for the PEDOT PANI and PEDOT-PB devices have been correlated to the particularly low magnitude of charge transfer resistance and high polarization capacitance operative at the PEDOT ionic liquid based electrolyte interface at these dc potentials, thus allowing facile ion-transport and consequently resulting in enhanced absorption modulation. Moderately fast switching kinetics and the ability of these devices to sustain about 2500 cycles of clear-to-dark and dark-to-clear without incurring major losses in the optical contrast, along with the ease of construction of these cells in terms of high scalability and reproducibility of the synthetic procedure for fabrication of the electrochromic films and the ionic liquid based gel electrolyte film, are indicators of the promise these devices hold for practical applications like electrochromic windows and displays.

    A simple and sensitive amperometric biosensor was developed for the screening of potential xanthine oxidase inhibitors from medicinal plants. This biosensor was prepared by immobilization of xanthine oxidase on the surface of prussian blue modified screen-printed electrodes using nafion and glutaraldehyde. The developed biosensor showed a linear amperometric response at an applied potential of +0.05 V toward the detection of hypoxanthine from 5 μM to 45 μM with a detection limit of 0.4 μM (S/N=3) and its sensitivity was found to be 600 mA M(-1) cm(-2). In addition, the biosensor exhibited a good storage stability. The inhibition of xanthine oxidase by allopurinol was studied under the optimized conditions. The linear range of allopurinol concentration is obtained up to 2.5 μM with an estimated 50% of inhibitionI50=1.8 μM. The developed biosensor was successfully applied to the screening of xanthine oxidase inhibitors from 13 medicinal plants belonging to different families. Indeed, Moroccan people traditionally use these plants as infusion for the treatment of gout and its related symptoms. For this purpose, water extracts obtained from the infusion of these plants were used for the experiments. In this work, 13 extracts were assayed and several of them demonstrated xanthine oxidase inhibitory effect, with an inhibition greater than 50% compared to spectrophotometry measurements that only few extracts showed an inhibition greater than 50%.

    The National Health System (ESY) in Greece, which was established in 1983, is in a state of continuous crisis. This situation is caused mainly by the system's problematic administration, low productivity and inadequate Primary Health Care. These have led the re-elected PASOK government to introduce by the end of 2000 a radical reform of the health system. The 200 reform measures announced by the new Minister of Health and Welfare include changes aiming at: the decentralization of the ESY, the creation of a unified financing system for the social insurance funds, a new management structure in public hospitals, the organization of a Primary Health System in urban areas, and the strengthening of Public Health and Health Promotion. These changes are presented and discussed in this paper.

    Full Text Available The paper discusses the role of the movement in the process of shaping the personality, its importance as a mechanism for personality development is considered. The issue of the movement has always occupied a central place in Russian psychology. However, subsequently the movement began to be considered primarily as an executive action in human life. The role of movement in personality development can vary depending on the level it occupies in the hierarchical structure of activity, and also on the type of movement, its character, and the way it is constructed. Under certain conditions, the movement can express the attitude of the subject to the surrounding world and people. Many foreign and Russian psychologists point to a special place of the postural tonic component of the motor movement, the posture in personal regulation. The posture reflects his/her personal attitudes, the system of relationships, and, above all, the emotional attitude or emotional assessment of the current situation, the interest in the actions performed. Mastering the tonic level of motor management is based on the emotional regulation, so the ability to regulate one’s own pose is an important stage in the personality development. Posture tonic regulation of motor movements in humans reveals a qualitatively different character than in animals, this being due to the person’s facing the task of mastering his’her posture, arbitrary retention of the body in one or another position. Maintaining a vertical posture requires constant activity at an arbitrary and involuntary level of mental regulation. Mastering the posture of an unstable equilibrium presupposes the emergence of the «I» and is the last stage of the development. The way a person solves the motor task of maintaining the vertical position of the body reflects his/her specific personal strategy or attitude.

    To provide an overview of paraneoplastic autoimmune disorders presenting with various movement disorders. The spectrum of paraneoplastic autoimmune disorders has been expanding with the discovery of new antibodies against cell surface and intracellular antigens. Many of these paraneoplastic autoimmune disorders manifest as a form of movement disorder. With the discovery of new neuronal antibodies, an increasing number of idiopathic or neurodegenerative movement disorders are now being reclassified as immune-mediated movement disorders. These include anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis which may present with orolingual facial dyskinesia and stereotyped movements, CRMP-5 IgG presenting with chorea, anti-Yo paraneoplastic cerebellar degeneration presenting with ataxia, anti-VGKC complex (Caspr2 antibodies) neuromyotonia, opsoclonus-myoclonus-ataxia syndrome, and muscle rigidity and episodic spasms (amphiphysin, glutamic acid decarboxylase, glycine receptor, GABA(A)-receptor associated protein antibodies) in stiff-person syndrome. Movement disorders may be a presentation for paraneoplastic autoimmune disorders. Recognition of these disorders and their common phenomenology is important because it may lead to the discovery of an occult malignancy. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Nuclear movement within a cell occurs in a variety of eukaryotic organisms including yeasts and filamentous fungi. Fungal molecular genetic studies identified the minus-end-directed microtubule motor cytoplasmic dynein as a critical protein for nuclear movement or orientation of the mitotic spindle contained in the nucleus. Studies in the budding yeast first indicated that dynein anchored at the cortex via its anchoring protein Num1 exerts pulling force on an astral microtubule to orient the anaphase spindle across the mother-daughter axis before nuclear division. Prior to anaphase, myosin V interacts with the plus end of an astral microtubule via Kar9-Bim1/EB1 and pulls the plus end along the actin cables to move the nucleus/spindle close to the bud neck. In addition, pushing or pulling forces generated from cortex-linked polymerization or depolymerization of microtubules drive nuclear movements in yeasts and possibly also in filamentous fungi. In filamentous fungi, multiple nuclei within a hyphal segment undergo dynein-dependent back-and-forth movements and their positioning is also influenced by cytoplasmic streaming toward the hyphal tip. In addition, nuclear movement occurs at various stages of fungal development and fungal infection of plant tissues. This review discusses our current understanding on the mechanisms of nuclear movement in fungal organisms, the importance of nuclear positioning and the regulatory strategies that ensure the proper positioning of nucleus/spindle.

    Thermal plasma technology can be efficiently used in the production of hydrogen and hydrogen-rich gases from methane and a variety of fuels. This paper describes progress in plasma reforming experiments and calculations of high temperature conversion of methane using heterogeneous processes. The thermal plasma is a highly energetic state of matter that is characterized by extremely high temperatures (several thousand degrees Celsius) and high degree of dissociation and substantial degree of ionization. The high temperatures accelerate the reactions involved in the reforming process. Hydrogen-rich gas (50% H{sub 2}, 17% CO and 33% N{sub 2}, for partial oxidation/water shifting) can be efficiently made in compact plasma reformers. Experiments have been carried out in a small device (2--3 kW) and without the use of efficient heat regeneration. For partial oxidation/water shifting, it was determined that the specific energy consumption in the plasma reforming processes is 16 MJ/kg H{sub 2} with high conversion efficiencies. Larger plasmatrons, better reactor thermal insulation, efficient heat regeneration and improved plasma catalysis could also play a major role in specific energy consumption reduction and increasing the methane conversion. A system has been demonstrated for hydrogen production with low CO content ({approximately} 1.5%) with power densities of {approximately} 30 kW (H{sub 2} HHV)/liter of reactor, or {approximately} 10 m{sup 3}/hr H{sub 2} per liter of reactor. Power density should further increase with increased power and improved design.

  15. The california electricity reform debacle

    International Nuclear Information System (INIS)

    Jaccard, M.

    2001-01-01

    In 1998, California launched a dramatic reform of its electricity sector, vertically de-integrating its major utilities and establishing a competitive generation market, with separate entities responsible for grid control and power exchange. After two uneventful years, wholesale prices rose dramatically in the summer of 2000 and have remained high into 2001. An imbalance between the high wholesale prices and frozen retail rates caused a financial crisis for the electric utilities and power shortages have been a chronic threat. Several factors contributed to this crisis: capacity has not expanded in step with demand either in California or its larger trading region; extreme weather and poorly timed plant outages further increased demand and decreased supply; market design flaws allowed significant suppliers to influence the market while frozen retail rates limited the demand response that would have mitigated the supply-demand imbalance. State and federal agencies have taken corrective action but the situation may remain critical for some time. Longer term solutions involve recognizing the special characteristics of electricity in designing marking reform. Because electricity supply and demand must be instantaneously balanced at all times, market reform must ensure that someone has the responsibility and effective tools to ensure that this occurs, in spite of unforeseen circumstances, and to prevent the exercise of market power. Because a competitive commodity market must work in concert with a monopoly delivery system, someone must be responsible and have the means to develop and operate the grid in ways that are amenable to effective competition. Finally, reform design must ensure that the cyclical investment and price patterns of normal commodity markets are minimized in the electricity market and that when they do occur, market volatility does not compromise reliability and price stability for those who value these highly and would pay a premium for them

    2010-03-01

    There are publications in which various neurological diseases are analysed on film. However, no references have been found on movement disorders in this medium. A total of 104 documents were collected and reviewed using the internet movie data base (IMDb). The majority were associated with dystonia, Parkinson's and tics, were American commercial productions, and the most common genre was drama. The cinema usually depicts old men with developed Parkinson's disease. However, motor complications only appear in 19% and non-motor symptoms in 14%. The image of dystonia is generally that of a young man, with disabling dystonia secondary to childhood cerebral palsy. Tics appear associated with Tourette's syndrome, with the excessive use of obscene expressions and with very few references to other important aspects of this syndrome, such as mood and behavioural changes. The majority of tremors portrayed on film are associated with Parkinsonism and are not pathological. Myoclonus appears anecdotically and is normally symptomatic. Parkinson's disease is the type of movement disorder that the cinema portrays with greater neurological honesty and in a more dignified manner.

  17. Power sector reforms in India

    Energy Technology Data Exchange (ETDEWEB)

    2007-07-01

    India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

  19. Reforming Science and Mathematics Education

    Science.gov (United States)

    Lagowski, J. J.

    1995-09-01

    Since 1991, the National Science Foundation has signed cooperative agreements with 26 states to undertake ambitious and comprehensive initiatives to reform science, mathematics, and technology education. Collectively, those agreements are known as the State Systemic Initiatives (SSI's). Two complimentary programs, The Urban and Rural Systemic Initiatives (USI's and RSI's), address similar reforms in the nation's largest cities and poorest rural areas. The SSI Program departs significantly from past NSF practice in several ways. The funding is for a longer term and is larger in amount, and the NSF is taking a more activist role, seeking to leverage state and private funds and promote the coordination of programs within states. The Initiatives also have a stronger policy orientation than previous NSF programs have had. The NSF strategy is a reflection of the growing and widely held view that meaningful reforms in schools are most likely to be achieved through state initiatives that set clear and ambitious learning goals and standards; align all of the available policy levers in support of reform; stimulate school-level initiatives; and mobilize human and financial resources to support these changes. Two premises underlie systemic reform: (1) all children can meet significantly higher standards if they are asked to do so and given adequate opportunities to master the content, and (2) state and local policy changes can create opportunities by giving schools strong and consistent signals about the changes in practice and performance that are expected. Because this is an enormous investment of Federal resources that is intended to bring about deep, systemic improvement in the nation's ability to teach science and mathematics effectively, the NSF has contracted with a consortium of independent evaluators to conduct a review of the program. The first of the SSI's were funded in 1991, sufficiently long ago to begin to formulate some initial impressions of their impact. Take

    2016-03-01

    Full Text Available This article describes (1 the relationship between the demands made by feminist movements of the 1970s in cases of sexual violence and criticism of the criminal justice system by these movements and other groups, including the prisoners’ movement; and (2 the relationship between this debate and the legal process of reforming the definition and punishment of rape. Two periods are analyzed. In the early 1970s, the common cause of very different movements targeting the law was the priority given to the defense against forms of repression and disciplinary institutions. After 1975, the demands of feminist and prisoner movements diverged and even conflicted. One camp called for an offensive approach to changing the legal punishment of rape whereas the other camp fought against penal reforms imposed by the government and, more specifically, against long sentences.

  3. Movement as utopia.

    Science.gov (United States)

    Couton, Philippe; López, José Julián

    2009-10-01

    Opposition to utopianism on ontological and political grounds has seemingly relegated it to a potentially dangerous form of antiquated idealism. This conclusion is based on a restrictive view of utopia as excessively ordered panoptic discursive constructions. This overlooks the fact that, from its inception, movement has been central to the utopian tradition. The power of utopianism indeed resides in its ability to instantiate the tension between movement and place that has marked social transformations in the modern era. This tension continues in contemporary discussions of movement-based social processes, particularly international migration and related identity formations, such as open borders transnationalism and cosmopolitanism. Understood as such, utopia remains an ongoing and powerful, albeit problematic instrument of social and political imagination.

    'Full text:' Auto-thermal reformers are used popularly for fuel cell vehicle because they are compact and can start up quickly. On the other hand, steam reformers are used for stationary fuel cell power plant because they are good thermal efficiency. While, there are many cases using the auto- thermal reformer for stationary use with expectation of cost reduction in USA, as well. However, they are still insufficient for its durability, compactness and cost. We have been developing the new type of fuel processing system that is auto-thermal steam reformer (ATSR), which is hybrid of a conventional steam reformer (STR) and a conventional auto-thermal reformer (ATR). In this study, some proto-type of ATSR for field test were designed, tried manufacturing and tested performance and durability. And we have tried to operate with fuel cell stack to evaluate the system interface performance, that is, operability and controllability. (author)

    The overall objective of the HiPHES project is to develop an advanced high-pressure heat exchanger for a convective steam/methane reformer. The HiPHES steam/methane reformer is a convective, shell and tube type, catalytic reactor. The use of ceramic tubes will allow reaction temperature higher than the current state-of-the-art outlet temperatures of about 1600 F using metal tubes. Higher reaction temperatures increase feedstock conversion to synthesis gas and reduce energy requirements compared to currently available radiant-box type reformers using metal tubes. Reforming of natural gas is the principal method used to produce synthesis gas (primarily hydrogen and carbon monoxide, H2 and CO) which is used to produce hydrogen (for refinery upgrading), methanol, as well as several other important materials. The HiPHES reformer development is an extension of Stone and Webster's efforts to develop a metal-tubed convective reformer integrated with a gas turbine cycle.

  6. Narratives of Public Health in Dickens's Journalism: The Trouble with Sanitary Reform.

    2015-01-01

    Although Dickens is still known as having been a highly visible supporter of England's well-known nineteenth-century sanitary movement, he became, in fact, deeply troubled by many of this movement's fundamental tenets, as evidenced by journal narratives on fever that he edited and wrote in the mid-nineteenth century. Rather than water and sewer engineering works and a sanitary regime policed by government agencies as envisaged by Edwin Chadwick and other sanitary reformers, Dickens's view by 1855 was that only a massive erasure of the existing social and political systems and their replacement by an utterly new infrastructure would suffice.

    This case study of Kenyan business trade licensing shows that red-tape costs can be cut if reform is championed strongly and there is a strong case in terms of costs and benefits. The reform of business registration, trade licensing and other business entry procedures is a cost effective and progressive way to promote indigenous private sector development. But, reform needs more than good cost-benefit analysis and legal drafting; it also requires building constituencies and continuous advocacy.

  15. Rate of Iron Transfer Through the Horse Spleen Ferritin Shell Determined by the Rate of Formation of Prussian Blue and Fe-desferrioxamine Within the Ferritin Cavity

    Science.gov (United States)

    Zhang, Bo; Watt, Richard K.; Galvez, Natividad; Dominquez-Vera, Jose M.; Watt, Gerald D.

    2005-01-01

    Iron (2+ and 3+) is believed to transfer through the three-fold channels in the ferritin shell during iron deposition and release in animal ferritins. However, the rate of iron transit in and out through these channels has not been reported. The recent synthesis of [Fe(CN)(sub 6)](3-), Prussian Blue (PB) and desferrioxamine (DES) all trapped within the horse spleen ferritin (HoSF) interior makes these measurements feasible. We report the rate of Fe(2+) penetrating into the ferritin interior by adding external Fe(2+) to [Fe(CN)(sub 6)](3-) encapsulated in the HoSF interior and measuring the rate of formation of the resulting encapsulated PB. The rate at which Fe(2+) reacts with [Fe(CN)(sub 6)](3-) in the HoSF interior is much slower than the formation of free PB in solution and is proceeded by a lag period. We assume this lag period and the difference in rate represent the transfer of Fe(2+) through the HoSF protein shell. The calculated diffusion coefficient, D approx. 5.8 x 10(exp -20) square meters per second corresponds to the measured lag time of 10-20 s before PB forms within the HoSF interior. The activation energy for Fe(2+) transfer from the outside solution through the protein shell was determined to be 52.9 kJ/mol by conducting the reactions at 10 to approximately 40 C. The reaction of Fe(3+) with encapsulated [Fe(CN)6](4-) also readily forms PB in the HoSF interior, but the rate is faster than the corresponding Fe(2+) reaction. The rate for Fe(3+) transfer through the ferritin shell was confirmed by measuring the rate of the formation of Fe-DES inside HoSF and an activation energy of 58.4 kJ/mol was determined. An attempt was made to determine the rate of iron (2+ and 3+) transit out from the ferritin interior by adding excess bipyridine or DES to PB trapped within the HoSF interior. However, the reactions are slow and occur at almost identical rates for free and HoSF-encapsulated PB, indicating that the transfer of iron from the interior through the

  17. A movement ecology paradigm for unifying organismal movement research.

    Movement of individual organisms is fundamental to life, quilting our planet in a rich tapestry of phenomena with diverse implications for ecosystems and humans. Movement research is both plentiful and insightful, and recent methodological advances facilitate obtaining a detailed view of individual movement. Yet, we lack a general unifying paradigm, derived from first principles, which can place movement studies within a common context and advance the development of a mature scientific discipline. This introductory article to the Movement Ecology Special Feature proposes a paradigm that integrates conceptual, theoretical, methodological, and empirical frameworks for studying movement of all organisms, from microbes to trees to elephants. We introduce a conceptual framework depicting the interplay among four basic mechanistic components of organismal movement: the internal state (why move?), motion (how to move?), and navigation (when and where to move?) capacities of the individual and the external factors affecting movement. We demonstrate how the proposed framework aids the study of various taxa and movement types; promotes the formulation of hypotheses about movement; and complements existing biomechanical, cognitive, random, and optimality paradigms of movement. The proposed framework integrates eclectic research on movement into a structured paradigm and aims at providing a basis for hypothesis generation and a vehicle facilitating the understanding of the causes, mechanisms, and spatiotemporal patterns of movement and their role in various ecological and evolutionary processes. "Now we must consider in general the common reason for moving with any movement whatever." (Aristotle, De Motu Animalium, 4th century B.C.).

    It long has been appreciated that humans behave irrationally in economic decisions under risk: they fail to objectively consider uncertainty, costs, and rewards and instead exhibit risk-seeking or risk-averse behavior. We hypothesize that poor estimates of motor variability (influenced by motor task) and distorted probability weighting (influenced by relevant emotional processes) contribute to characteristic irrationality in human movement decisions.

    Full Text Available Today, the juxtaposition between physical bodies and the gameworld is ever more fluid. Virtual Reality headsets are available at game stores with more AAA games being created for the format. The release of the Nintendo Switch and its dynamic JoyCon controllers reintroduce haptic movement based controls.  Pokémon GO’s augmented reality took gamers outdoors and has encouraged the Harry Potter franchise to follow in its mobile footsteps. Each development encourages a step further into the digital world. At the same time, the movement of bodies always has political dimensions. We live in a world where walls seem like solutions to the movement of bodies, while the mere meeting of bodies elsewhere – for sex, marriage and other reasons – is still forbidden by many states’ rules. Games and game-like interfaces have shown the ability to bend those rules, and to sometimes project other worlds and rule systems over our world in order to make bodies move and meet. For this special issue on ‘Body Movements’, Press Start invited authors to focus on embodiment, body movements, political bodies, community bodies, virtual bodies, physical bodies, feminine, masculine, trans- bodies, agency or its lack, and anything else in between. The response to this invitation was variegated, and provocative, as outlined here.

This movement implemented shmita (sabbatical year practices, which Jewish law mandates only inside the land of Israel, in the United States during the shmita year that began in September 2014. This article offers a brief historical overview of shmita and then utilizes the main texts of the shmita movement to explore how the Shmita Project connects- the diverse worlds of Judaism, environmentalism, ethics, and food reform. The Shmita Project encapsulates a multivalent environmentalist strain of American Judaism that is deeply concerned with climate change, industrial agriculture, and food injustice. The unprecedented- observance- of an American shmita year, focused on land stewardship and food security, is emblematic- of this movement’s efforts towards sustainable agriculture, animal welfare, and repairing the American food system through practices that are inspired by Jewish tradition and values.

The author notes that, in our society, it is no longer acceptable to be racist, but it is still okay to be homophobic. The many campaigns against gay marriage and efforts in the legislature to prevent change toward equal civil rights and protections are prime examples. In our current political climate, two things are very clear: (a) homophobia is freely tolerated and (b) the times are changing as we inch closer to equal rights every day. We are "righting wrongs and reforming rights."

  13. Welfare implication of reforming energy consumption subsidies

    Breton, Michèle; Mirzapour, Hossein

    2016-01-01

    Reforming energy consumption subsidies, in particular for fossil fuels, has been frequently referred to as a quick-win policy to enhance environmental mitigation. In addition, the removal of such subsidies may release a sizeable portion of a country's national budget for use on more productive targets. One of the most recognized challenges of such reform is “selling” the new energy prices to citizens, particularly those with a more fragile purchasing power. Several empirical and technical studies have prescribed that the reform might be supported by a direct compensation mechanism in order to ensure feasibility. This is what was done during the recent energy subsidy reform in Iran. However, the compensation mechanism implemented in Iran's reform was successful at the beginning, but did not proceed as expected. This has raised questions about the feasibility and sustainability of the direct compensation mechanism, and even of the reform policy itself. In this paper, we consider a stylized model where direct compensation is the instrument proposed to restore consumers’ utility against increased energy prices. We find that, when prices of Other Goods are affected by the announced reform policy, the feasibility of a subsidy reform critically depends on the value of certain parameters: the initial subsidization rate, the share of energy in the consumers’ bundle, and the energy portion of price of Other Goods. - Highlights: • A model of energy subsidy reform with direct compensation is proposed. • Feasibility of the reform is related to three key parameters. • An illustrative example using data from the recent Iranian reform is discussed.

    2015-06-01

    Full Text Available The paper provides an overview of the land reform in Russia's recent history. Analysis of land reform, which started in 1990, shows what actions and what logic led the land sector in the state in which it was at the finish line of the quarter-century reform marathon. The reform process was not linear, it highlighted the steps differing objectives and strategies to achieve them. Land reform is presented as a struggle of different political forces, which were reflected in the redistribution of functions between agencies in lobbying for appointment to senior positions promoted various commands. The authors conclude about the gradual displacement of state regulation of land relations, the deliberate destruction of the land management as a basis for the development of land resources.

    Full Text Available Combined (steam and CO2 reforming is one of the methods to produce syngas for different applications. An energy requirement analysis of steam reforming to dry reforming with intermediate steps of steam reduction and equivalent CO2 addition to the feed fuel for syngas generation has been done to identify condition for optimum process operation. Thermodynamic equilibrium data for combined reforming was generated for temperature range of 400–1000°C at 1 bar pressure and combined oxidant (CO2 + H2O stream to propane (fuel ratio of 3, 6, and 9 by employing the Gibbs free energy minimization algorithm of HSC Chemistry software 5.1. Total energy requirement including preheating and reaction enthalpy calculations were done using the equilibrium product composition. Carbon and methane formation was significantly reduced in combined reforming than pure dry reforming, while the energy requirements were lower than pure steam reforming. Temperatures of minimum energy requirement were found in the data analysis of combined reforming which were optimum for the process.

    Movement disorders can be defined as neurological syndromes presenting with excessive or diminished automatic or voluntary movements not related to weakness or spasticity. Both Parkinson's disease (PD) and Huntington's disease (HD) are well-known examples of these syndromes. The high prevalence of comorbid psychiatric symptoms like depression, anxiety, obsessive-compulsive symptoms, hallucinations, delusions, impulsivity, sleep disorders, apathy and cognitive impairment mean that these conditions must be regarded as neuropsychiatric diseases. In this article, we review neuroanatomical (structural and functional), psychopathological and neuropsychological aspects of PD and HD. The role of fronto-subcortical loops in non-motor functions is particularly emphasised in order to understand the clinical spectrum of both diseases, together with the influence of genetic, psychological and psychosocial aspects. A brief description of the main psychopharmacological approaches for both diseases is also included. Copyright © 2017 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

  17. Environmental consequences of electricity sector reforms

    International Nuclear Information System (INIS)

    Wohlgemuth, N.

    1999-01-01

    Worldwide, the electricity industry is in the process of undergoing fundamental transitions. The reform process typically involves one or more of the following changes: commercialisation, privatisation, unbundling/restructuring and introduction of competition. The environmental impacts of these changes pull in different directions. There is concern that restructured electricity markets may not always incorporate adequately the environmental impacts of electricity resource development and consumption decisions. However, the electricity sector reform process also offers an opportunity to promote positive environmental changes: because the sector is already in flux, it may be easier to address environmental issues. The paper gives an overview of power sector reform in six countries where reforms have already been implemented, and concludes that reform measures will have to be accompanied by competitively neutral regulations in order to stimulate investment in environmentally sound technologies, including renewable and energy efficient technologies.

In Indonesian context, the Islamism at least have four characteristics; (i promoting Islam as a sole basis in transforming society, (ii acknowledging Islam as an ideology, (iii among at the establishment of Islamic state, (iv which is characterised by implementing Shari`ah laws in daily lives. These four attributes may be used in capturing the growth of Muslim’s perception on state and democracy in the era of Islamic revival. The above views spread in the various streams or any schools existed in Indonesia, both Islamic movements and other form that is very influential in the process of democracy in Indonesia.

  19. Reform despite politics? The political economy of power sector reform in Fiji, 1996–2013

    International Nuclear Information System (INIS)

    Dornan, Matthew

    2014-01-01

    Attempts to reform the electricity sector in developing countries have achieved mixed results, despite the implementation of similar reforms in many developed countries, and concerted effort by donors to transfer reform models. In many cases, political obstacles have prevented full and effective implementation of donor-promoted reforms. This paper examines the political economy of power sector reform in Fiji from 1996 to 2013. Reform has been pursued with political motives in a context of clientelism. Policy inconsistency and reversal is explained by the political instability of ethnic-based politics in Fiji. Modest success has been achieved in recent years despite these challenges, with Fiji now considered a model of power sector reform for other Small Islands Developing States (SIDS) in the Pacific. The experience demonstrates that reform is possible within difficult political environments, but it is challenging, takes time and is not guaranteed. The way in which political motives have driven and shaped reform efforts also highlights the need for studies of power sector reform to direct greater attention toward political drivers behind reform. - Highlights: • This is the first study of power sector reform in Fiji or other Small Island Developing States (SIDS) of the Pacific. • The clientelist nature of politics in Fiji is found to have both driven and shaped reform efforts. • There has been modest success in recent years despite these obstacles, with Fiji now considered a model for other SIDS. • The experience demonstrates that reform is possible within difficult political environments, but it is challenging, takes time and is not guaranteed

    2012-06-01

    Several movement disorders may occur during nocturnal rest disrupting sleep. A part of these complaints is characterized by relatively simple, non-purposeful and usually stereotyped movements. The last version of the International Classification of Sleep Disorders includes these clinical conditions (i.e. restless legs syndrome, periodic limb movement disorder, sleep-related leg cramps, sleep-related bruxism and sleep-related rhythmic movement disorder) under the category entitled sleep-related movement disorders. Moreover, apparently physiological movements (e.g. alternating leg muscle activation and excessive hypnic fragmentary myoclonus) can show a high frequency and severity impairing sleep quality. Clinical and, in specific cases, neurophysiological assessments are required to detect the presence of nocturnal movement complaints. Patients reporting poor sleep due to these abnormal movements should undergo non-pharmacological or pharmacological treatments.

    Breyer, Nike Ulrike

    2011-01-01

    The nineteenth century "movement for rational clothing" not only aimed at reforming women's clothes (leaving behind corset-fashion), it set out to improve women's rights in general. Few people know that footwear also was modernized in the second half of the nineteenth century. After shoes had been made for 350 years on the basis of a symmetry pattern, without or with almost invisible distinction between left and right feet, scientists around the Frankfurt born professor of anatomy Georg Hermann von Meyer (1815-1892) demanded with him radical reform of footwear--for both sexes--using new lasts that were modelled on the natural shape of feet. Around the turn of the century, after physicians, shoemakers and hygienists had spent decades debating new ideas, members of the Wandervogel movement adopted the issue for their own purposes and chose anatomic over fashionable yet unhealthy fits which tended to be pointed, slim and--above all--symmetrical. Once the Wandervogel movement had split into several smaller groupings in 1904 and become part of the Jugendbewegung (youth movement), some of its members wanted clothing to also carry symbolic meaning. Naturally-shaped hygienic boots should no longer just allow for walking without damage to the feet: they should become the embodiment of a new spirit and, beyond that, of a reformed society. A new "lay practice" and "do-it-yourself"-shoemaking replaced former academic programs for new natural footwear. Interestingly enough, alongside those quite radical concepts, a kind of "footwear reform light" established itself in the market: on the surface only slightly different from the old-fashioned, symmetrical shoes, these "modern" pairs, which consisted of a right and left shoe, remained successful even after the world wars and became the new standard in the twentieth century, because the shoes made according to this pattern lasted longer, fitted better and were more comfortable.

    2013-01-01

    The Fukushima Daiichi NPP accident deeply questioned the bases of nuclear safety and nuclear safety regulation in Japan. It also resulted in a considerable loss of public confidence in the safety of nuclear power across the world. Although the accident was caused by natural phenomena, institutional and human factors also largely contributed to its devastating consequences, as shown by the Japanese Diet's and Government's investigation reports. 'Both regulators and licensees were held responsible and decided to fully reconsider the existing approaches to nuclear safety. Consequently, the regulatory system underwent extensive reform based on the lessons learned from the accident,' Yoshihiro Nakagome, the President of Japan Nuclear Energy Safety Organisation, an ETSON member TSO, explains.

    This paper provides an outlook of the electricity market reform in Greece which started in 2001 and is still developing slowly. This is related to the persisting dominance of the incumbent company and the specificities of the electricity sector of Greece which is heavily dependent on indigenous lignite firing generation, while being located in the periphery of the EU internal electricity and gas markets. Competition through enhancing electricity trade in the region is limited to date, as the establishment of an internal market in South East Europe also progresses slowly. Development of competition through gas-firing generation by new entrants has been the priority adopted by State and Regulator's policies. However, the gas supply market in Greece and in the region still lags behind. (author)

    Yanuzova, M

    1991-12-01

    Labor legislation reforms contained in Law 50 of 1990 were intended to facilitate international opening of Colombia's economy, which has been beset by external debt, an absence of foreign investment, technological backwardness, and low productivity. The weakness of the labor movement, aggravated by the failure of the socialist economic model and its power organization, made possible a dismantling of past labor victories. The labor reform is intended to combat stagnation in productivity which is believed by the government to result from labor instability; to create a climate permitting generation of employment, and to adapt internal labor laws to recommendations of the International Labour Organization. The effort to make labor legislation more flexible and more adaptable to market conditions removed some protectionist measures and facilitated firing or laying off of workers. Several categories of workers were removed from the jurisdiction of labor laws and placed under the jurisdiction of civil law and ultimately of market forces. The new labor law will lead to salary reductions for most workers. A 36-hour work week without overtime was created for new enterprises as a strategy to encourage job creation. The principle that labor laws should protect workers because of their unequal power relative to employers has been suppressed in the new legislation. Although it is too early to draw definite conclusions about the effect of the law on women workers, some effects are predictable. The liberating power of employment for married women has been limited in Colombia as in many other countries because women are expected to carry out their full traditional domestic role in addition to their paid employment. Women's status in the workplace has improved considerably over the past 50 years, but they still have higher unemployment rates than men, receive lower wages, and are concentrated in less skilled jobs and the informal sector. Employment in the informal sector allows

    2010-01-01

    In early 1990 the power sector in India required an initial set of reforms due to the scarcity of financial resources and its deteriorating technical and commercial efficiency. The Indian power sector is now going through a second stage of reforms in which restructuring of electric supply utilities has taken place. The Maharashtra State Electricity Board (MSEB) initiated reforms in 2005 by dividing the state electricity board into four separate companies. In this paper, the situations that led to the reform of the MSEB and the scope of the work required for an action plan initiated by the state electricity distribution company in the context of the proposed Key Performance Index are discussed. The post-reform status of the distribution company is analyzed with selected key parameters. The study also analyzes the electricity supply model implemented and the effect of a multi-year tariff plan as one of the key milestones of the tariff structure. The various new projects implemented by the distribution company to improve consumer services and the reform experiences of the other states are discussed, along with the future scope of the present reform process.

    2010-05-13

    It has been proposed that individuals with autism have difficulties understanding the goals and intentions of others because of a fundamental dysfunction in the mirror neuron system. Here, however, we show that individuals with autism exhibited not only normal fMRI responses in mirror system areas during observation and execution of hand movements but also exhibited typical movement-selective adaptation (repetition suppression) when observing or executing the same movement repeatedly. Movement selectivity is a defining characteristic of neurons involved in movement perception, including mirror neurons, and, as such, these findings argue against a mirror system dysfunction in autism.

    Stereotypic movements are repetitive, rhythmic, fixed, patterned in form, amplitude, and localization, but purposeless (e.g., hand shaking, waving, body rocking, head nodding). They are commonly seen in children; both in normal children (primary stereotypy) and in individuals with additional behavioral or neurological signs and symptoms (secondary stereotypy). They should be differentiated from compulsions (OCD), tics (tic disorders), trichotillomania, skin picking disorder, or the direct physiological effect of a substance. There is increasing evidence to support a neurobiological mechanism. Response to behavioral and pharmacological therapies is variable. Copyright © 2011 Elsevier B.V. All rights reserved.

  15. The tactile movement aftereffect.

    Science.gov (United States)

    Hollins, M; Favorov, O

    1994-01-01

    The existence of a tactile movement aftereffect was established in a series of experiments on the palmar surface of the hand and fingers of psychophysical observers. During adaptation, observers cupped their hand around a moving drum for up to 3 min; following this period of stimulation, they typically reported an aftereffect consisting of movement sensations located on and deep to the skin, and lasting for up to 1 min. Preliminary experiments comparing a number of stimulus materials mounted on the drum demonstrated that a surface approximating a low-spatial-frequency square wave, with a smooth microtexture, was especially effective at inducing the aftereffect; this adapting stimulus was therefore used throughout the two main experiments. In Experiment 1, the vividness of the aftereffect produced by 2 min of adaptation was determined under three test conditions: with the hand (1) remaining on the now stationary drum; (2) in contact with a soft, textured surface; or (3) suspended in air. Subjects' free magnitude estimates of the peak vividness of the aftereffect were not significantly different across conditions; each subject experienced the aftereffect at least once under each condition. Thus the tactile movement aftereffect does not seem to depend critically on the ponditions of stimulation that obtain while it is being experienced. In Experiment 2, the vividness and duration of the aftereffect were measured as a function of the duration of the adapting stimulus. Both measures increased steadily over the range of durations explored (30-180 sec). In its dependence on adapting duration, the aftereffect resembles the waterfall illusion in vision. An explanation for the tactile movement aftereffect is proposed, based on the model of cortical dynamics of Whitsel et al. (1989, 1991). With assumed modest variation of one parameter across individuals, this application of the model is able to account both for the data of the majority of subjects, who experienced the

    Rayburn, W F

    1990-03-01

    Recording fetal activity serves as an indirect measure of central nervous system integrity and function. The coordination of whole body movement, which requires complex neurologic control, is likely similar to that of the newborn infant. Short-term observations of the fetus are best performed using real-time ultrasound imaging. Monitoring fetal motion has been shown to be clinically worthwhile in predicting impending death or compromise, especially when placental insufficiency is longstanding. The presence of a vigorous fetus is reassuring. Perceived inactivity requires a reassessment of any underlying antepartum complication and a more precise evaluation by fetal heart rate testing or real-time ultrasonography before delivery is contemplated.

    Advances in fuel cell applications reflect the ability of reformers to produce hydrogen. This work presents a flexible micro temperature sensor that is fabricated based on micro-electro-mechanical systems (MEMS) technology and integrated into a flat micro methanol reformer to observe the conditions inside that reformer. The micro temperature sensor has higher accuracy and sensitivity than a conventionally adopted thermocouple. Despite various micro temperature sensor applications, integrated micro reformers are still relatively new. This work proposes a novel method for integrating micro methanol reformers and micro temperature sensors, subsequently increasing the methanol conversion rate and the hydrogen production rate by varying the fuel supply rate and the water/methanol ratio. Importantly, the proposed micro temperature sensor adequately controls the interior temperature during oxidative steam reforming of methanol (OSRM), with the relevant parameters optimized as well.

    2018-01-01

    The United Nations Convention against Illicit Traffic in Narcotic Drugs 1988 ("1988 Convention") expresses a strong normative preference for criminalising drug possession. Historically, the United Nations offices responsible for overseeing the treaties have held that decriminalisation of drug possession is contrary to the treaties. Leading up to and during UNGASS 2016, however, rather than emphasise criminalisation, the high-ranking officials from the drug control offices emphasised the treaties' allowance of alternatives to punishment for drug possession offences. This paper applies transnational social movement theory to analyse the political opportunity structure for drug law reform at the UN. Data was collected from documents created by important United Nations agencies in the lead up to UNGASS 2016. By analysing the statements of prominent UN officials within a social movement theory framework, we can assess whether those responsible for administering global drug policy are offering concession to drug law reform social movement and whether a political opportunity structure is opening up for drug law reformers to pursue further reforms. from the United Nations documents demonstrated significant reference to local drug law reforms and the benefits of non-punitive treatment of drug users. However, given the strong normative preference and mandatory language ("shall") in the 1988 Convention, policy leaders at the UN can only offer very moderate concessions to drug law reformers - primarily the advocacy of alternatives to incarceration. Such policies still suffer many problems caused by using the criminal justice system to funnel people into treatment. Indeed, many other offices at the UN explicitly drew attention to the problem of pre-trial punishment in their contributions to UNGASS 2016. A schism is developing at the UN as other UN offices are pointing out that advocating for alternatives to punishment is inadequate due to the many problems of "pre

  7. Does the Energy Sector Reform Call for Reform

    2007-01-01

    This paper discusses the course of the energy sector reforms in Europe so far, its objectives, achievements, issues, and dilemmas. In particular, long term and security aspects of energy supply of Europe are analyzed. In addition to the legislative changes regarding the open energy market regulation, and primarily the changes, concerning electricity and natural gas markets, the past period saw dynamic changes of institutional framework such as: increasing members of the European Union, increased number of countries aspiring to the EU (candidate countries and potential candidates), changes in other European countries out of which Russia is the most significant energy producer. The paper analyzes the issue of responsibility between state - regulator - system operator - trader - energy buyer. In Europe, it is more a complex question because the system of responsibility includes the institution of the European Union. Therefore, the relations between EU - state - regulator - system operator - trader - energy buyer are especially important. The paper looks in to the issue of energy company integrations, creation of energy mega-undertakings and their influence on further market development. The question of monopolies now appears in s new form. The conclusions suggest possible measures for institutional influence on energy market development, especially in the network energy systems, which may have a positive impact on system security and stability and markets development and their long term sustainability.(author)

  8. A background to the feminist movement in Egypt.

    Hoodfar, H

    1992-01-01

    The origins of the feminist movement in Egypt can be traced back to the social restructuring that occurred during the reign of Mohammed Ali (1805-48). At that time, a debate raged over whether female education was essential to national development. Reformers such as Kassim Amin argued in favor of education for all women and condemned polygamy, supporting their arguments with references to the Koran. Women from the upper classes used their wealth, over which Muslim law gives them full control, to found hospitals, schools, and training centers. By 1914, there were 14 magazines devoted to women's issues. Women participated in anticolonial movements and nationalist party activities while continuing to advocate improvements in women's status. In 1924, Egypt became the 1st Islamic country to deveil women without state intervention. The Egyptian Feminist Party was founded in 1923, and the Women's Political Party was established in 1942 to coordinate the fight for women's equality and the revision of family law. Women's full political rights gained recognition when Egypt won independence in 1956, and the 1st female Minister, Hekmat Abu-Zaid, was appointed in 1962. Ironically, the feminist movement stagnated in the 1st few decades after independence as women's organizations became coopted into the state. The movement has been revitalized, however, by Islamic attacks on women's rights.

    Full Text Available The essay depicts an attempt to reform ortography taken by a military doctor Đuro Augustinović through which he strived to unify the Southslavic people, especially the Croats and the Serbs. The potential movements that he was exposed to and that he was influenced by were stated in the essay, along with his persevere promotion of his own standpoint. Since his proposal appeared in amidst of Gaj's triumphant orto-graphical proposals, his ideas were not widely accepted. In the spirit of ongoing Panslavic movements Augustinović insisted on reconstruction of Latin script by introducing Cyrillic graphems (in opposition to Gaj's solutions which involved diacritic signs intending to unify in writing the two bigger nations. This equilization of Cyrillic and Latin script failed because both, the Croats and the Serbs had a deep-rooted tradition which prevented every intervention in its core. His untiring advocating of phonetical solutions in ortographical issues had a similar destiny. Therefore, Augustinović's attempt remained solely a testimony of an era without a true impact.

  10. Mega-mining in Mexico. Structural reforms and resistance

    Darcy Tetreault

    2013-11-01

    Full Text Available This article analyzes the structural causes of social environmental conflicts around mega-mining in Mexico and describes the emergence and coordination of resistance movements. It argues that neoliberal reforms have facilitated ‘accumulation by dispossession’ on two levels: first, by transferring public resources in the form of mineral reserves and state-run mining companies to the private sector; and second, bydispossessing smallholder farmers and indigenous communities of their land, water and cultural landscapes, in order to allow mining companies to carry out their activities. Furthermore, it argues that some factions of the resistance movements reflect ‘the environmentalism of the poor’ insofar as they seek to maintain natural resources outside of the sphere of the capitalist mode of production. Through a systematic revision of newspaper articles, blogs and scholarly publications, 29 high-profile eco-territorial mining conflicts are identified and a preliminary analysis of these is provided.

    This report reviews and analyzes the recent electricity reforms in Argentina, Australia, and the United Kingdom (UK) to illustrate how different models of privatization and reform have worked in practice. This report also analyzes the motivations of the U.S. companies who have invested in the electricity industries in these countries, which have become the largest targets of U.S. foreign investment in electricity. Two calculations of foreign investment are used. One is the foreign direct investment series produced by the U.S. Department of Commerce. The other is based on transactions in electric utilities of the three countries. The electricity reform and privatization experiences reviewed may offer some insight as to how the U.S. electricity industry might develop as a result of recent domestic reform efforts and deregulation at the state and national levels. 126 refs., 23 figs., 27 tabs.

    Carbonaceous deposits on naphtha reforming catalysts play a decisive role in limiting process performance. The deposits negatively after catalyst activity, selectivity and the production cycle of a semi regenerative reformer. The magnitude of negative effect of those deposits is directly proportional to their amounts and complexity. Investigations on used reforming catalysts samples reveal that the amount and type (complexity of the chemical nature) of carbonaceous deposits are directly proportional to the catalysts life on stream and the severity of operating conditions. In addition, the combustibility behavior of carbonaceous deposits on the catalyst samples taken from different reformers are found to be different. Optimal carbon removal, for in situ catalyst regeneration, requires the specific conditions be developed, based on the results of well designed and properly performed investigations of the amount and type of carbonaceous deposits.

    2017-05-01

    Full Text Available The purpose of this paper is to examine the impact of Indonesia’s tax reforms of 2000 and 2008/2009 on taxpayers’ noncompliance. Noncompliance is defined as the difference between the Value Added Tax (VAT liability and the actual revenue. Data are mainly collected from the World Input-Output Database and Indonesia’s Central Board of Statistics. The methodology uses one of the ‘top-down’ approaches, in which national accounts figures are employed to arrive at an estimation of the VAT liability. It is found that compliance deteriorated when reform efforts were incomplete – that is when the reforms suffered from decelerations, setbacks or reversals. This paper contributes to the literature by providing a framework for analyzing the impact of tax reform on taxpayer’s compliance behavior.

  1. The Reformed tradition as public theology

    2013-05-01

    Full Text Available This article is a South African perspective of a Black African reflection on the publicity of Reformed faith. Whilst the notion of public theology is fairly new, the article argues, it is important to define the ‘public’ of the type of public theology to which Reformed faith and tradition could be linked. As a confessional tradition, Reformed faith is intrinsically public, the article demonstrates. The publicity of this tradition is however ambivalent and tainted. I attempt to show this by discussing two important tenets of the Reformed Tradition: sola scriptura and sola fide, within the festering wounds of Black African colonialism, apartheid and the hegemony of the neoliberal paradigm in the 21st century.

    The Russian Government is pursuing a strategy of very high economic growth, with the objective of doubling gross domestic product in ten years. It recognises the central role the electricity sector has to play to achieve this target and has embarked on a highly ambitious program of electricity reform. If it is to succeed, the reform program will have to create market structures, market rules and a regulatory framework that will foster competitive wholesale and retail electricity markets. At the same time, it will have to deal with sensitive social issues related to tariff rebalancing and the removal of cross subsidies. Only competitive markets based on transparent prices that reflect costs can deliver the efficient, reliable and internationally competitive performance needed to meet the government's economic targets. Such markets are essential to attract new investment that will be required to ensure security of electricity supply after 2010. This book focuses on key aspects of the proposed reform that could have an important bearing on its success. It also raises concerns as to the pace of reform in related areas, such as the need for complementary reforms in the Russian natural gas sector. The IEA commends the Russian Government on its efforts to embrace this electricity reform - a key element critical to meeting the challenges ahead in terms of its economic growth and energy security. 17 figs., 10 tabs., 3 maps.

    Ten temporomandibular joints (TMJs) of 5 healthy volunteers and 19 TMJs of internal derangements in 16 patients with splint therapy were examined with MR imaging. T1-weighted images were obtained only in the closed mouth position, and gradient recalled acquisition in steady state (GRASS) images were obtained in active opening and closing phases, allowing a pseudodynamic display of TMJ movement. All patients received protrusive splint treatment. The usefulness of MR imaging to assess the efficacy of splint therapy was evaluated. Corrected disk position with the splint in place was clearly demonstrated in 9 TMJs, corresponding with elimination of reciprocal clicking. Ten other TMJs of anterior disk displacement without reduction showed uncorrected disk position by the splint. This information could confirm the therapeutic efficacy, or suggest other treatment alternatives. GRASS MR imaging can provide accurate and physiologic information about disk function in initial and follow-up assessment of protrusive splint therapy. (orig.)

The chapter follows in the wake of a growing attention to the aspects of everyday life and lived life at school in the history of education. It also develops tools for and demonstrates how...... the use of spoken memories is a rewarding source for the writing about school from the pupils’ perspective....

    Health policy debates are replete with discussions of federalism, most often when advocates of reform put their hopes in states. But health policy literature is remarkably silent on the question of allocation of authority, rarely asking which levels of government ought to lead. We draw on the larger literatures about federalism, found mostly in political science and law, to develop a set of criteria for allocating health policy authority between states and the federal government. They are social justice, procedural democracy, compatibility with value pluralism, institutional capability, and economic sustainability. Of them, only procedural democracy and compatibility with value pluralism point to state leadership. In examining these criteria, we conclude that American policy debates often get federalism backward, putting the burden of health care coverage policy on states that cannot enact or sustain it, while increasing the federal role in issues where the arguments for state leadership are compelling. We suggest that the federal government should lead present and future financing of health care coverage, since it would require major changes in American intergovernmental relations to make innovative state health care financing sustainable outside a strong federal framework.

  3. Hospital Acquisitions Before Healthcare Reform.

    The hospital industry has experienced increased consolidation in the past 20 years. Since 2010, in particular, there has been a large rise in the number of hospital acquisitions, and observers have suggested this is due in part to the expected impact of federal healthcare reform legislation. This article reports on a study undertaken to identify the market, management, and financial factors affecting acute care, community hospitals acquired between 2010 and 2012. We identified 77 such hospitals and compared them to other acute care facilities. To assess how different factors were associated with acquisitions, the study used multiple logistic regressions whereby market factors were included first, followed by management and financial factors. Study findings show that acquired hospitals were located in markets with lower rates of preferred provider organization (PPO) penetration compared with nonacquired hospitals. Occupancy rate was found to be inversely related to acquisition rate; however, case-mix index was significantly and positively related to a hospital's being acquired. Financial factors negatively associated with a hospital's being acquired included age of plant and cash flow margin. In contrast to the findings from earlier studies of hospital acquisitions, our results showed that acquired hospitals possessed newer assets. However, similar to the findings of other studies, the cash flow margin of acquired hospitals was lower than that of nonacquired facilities.

  4. Abortion law reform in Nepal.

    Across four decades of political and social action, Nepal changed from a country strongly enforcing oppressive abortion restrictions, causing many poor women's long imprisonment and high rates of abortion-related maternal mortality, into a modern democracy with a liberal abortion law. The medical and public health communities supported women's rights activists in invoking legal principles of equality and non-discrimination as a basis for change. Legislative reform of the criminal ban in 2002 and the adoption of an Interim Constitution recognizing women's reproductive rights as fundamental rights in 2007 inspired the Supreme Court in 2009 to rule that denial of women's access to abortion services because of poverty violated their constitutional rights. The government must now provide services under criteria for access without charge, and services must be decentralized to promote equitable access. A strong legal foundation now exists for progress in social justice to broaden abortion access and reduce abortion stigma. Copyright © 2014 International Federation of Gynecology and Obstetrics.

  5. Health Reform Requires Policy Capacity

    2015-05-01

    Full Text Available Among the many reasons that may limit the adoption of promising reform ideas, policy capacity is the least recognized. The concept itself is not widely understood. Although policy capacity is concerned with the gathering of information and the formulation of options for public action in the initial phases of policy consultation and development, it also touches on all stages of the policy process, from the strategic identification of a problem to the actual development of the policy, its formal adoption, its implementation, and even further, its evaluation and continuation or modification. Expertise in the form of policy advice is already widely available in and to public administrations, to well-established professional organizations like medical societies and, of course, to large private-sector organizations with commercial or financial interests in the health sector. We need more health actors to join the fray and move from their traditional position of advocacy to a fuller commitment to the development of policy capacity, with all that it entails in terms of leadership and social responsibility

    Full Text Available The article includes analysis of the main reasons for activization of separatism movements in Xinjiang later in XX and earlier in XXI centuries. The author comes into conclusion that the following reasons caused the process of active politicization of ethnicity in Central Asian region and wide territories of Xinjiang: changes in the territory of former Soviet Union countries; economic recession in former Soviet Union countries which led to activization of radical movements; economic reforms in China leading to liberalization of social and political spheres; influence of external global factors. The mentioned changes resulted in serious activization of separatist tendencies which was not the case in earlier periods.

    There are diverse religious groups which have developed special forms of "methodical lifestyle" (Max Weber). Projects of life reform and new religious movements around 1900 brought up specific ways of living and influenced one another in respect to ideas and practices. Using the example of the Mazdaznan-Movement some forms of interdependencies will be demonstrated. Since the group formed in the U.S.A. at the turn of the 20th century I will try to contextualize its central practices such as vegetarianism, intestinal care and breathing exercises within the specific context of American cultural and religious history.

  8. High temperature nuclear heat for isothermal reformer

    International Nuclear Information System (INIS)

    Epstein, M.

    2000-01-01

    High temperature nuclear heat can be used to operate a reformer with various feedstock materials. The product synthesis gas can be used not only as a source for hydrogen and as a feedstock for many essential chemical industries, such as ammonia and other products, but also for methanol and synthetic fuels. It can also be burnt directly in a combustion chamber of a gas turbine in an efficient combined cycle and generate electricity. In addition, it can be used as fuel for fuel cells. The reforming reaction is endothermic and the contribution of the nuclear energy to the calorific value of the final product (synthesis gas) is about 25%, compared to the calorific value of the feedstock reactants. If the feedstock is from fossil origin, the nuclear energy contributes to a substantial reduction in CO 2 emission to the atmosphere. The catalytic steam reforming of natural gas is the most common process. However, other feedstock materials, such as biogas, landfill gas and CO 2 -contaminated natural gas, can be reformed as well, either directly or with the addition of steam. The industrial steam reformers are generally fixed bed reactors, and their performance is strongly affected by the heat transfer from the furnace to the catalyst tubes. In top-fired as well as side-fired industrial configurations of steam reformers, the radiation is the main mechanism of heat transfer and convection heat transfer is negligible. The flames and the furnace gas constitute the main sources of the heat. In the nuclear reformers developed primarily in Germany, in connection with the EVA-ADAM project (closed cycle), the nuclear heat is transferred from the nuclear reactor coolant gas by convection, using a heating jacket around the reformer tubes. In this presentation it is proposed that the helium in a secondary loop, used to cool the nuclear reactor, will be employed to evaporate intermediate medium, such as sodium, zinc and aluminum chloride. Then, the vapors of the medium material transfer

    Full Text Available This article aims to describe Islamic religious thought of Muslim student at KhairunUniversity in Ternate and the dynamic of religious movement organizations on  campus. Informants of this study were selected using purposive method including activists of  Islamic organizations, students, and lecturers of the university. Data were collected using interviews, observation, and documentation, and searching data related to social context of the study from the internet. Findings of the research shows that the type of religious understanding and nationality of Muslim students after the reformation era at Khairun University began experiencing a shift since the presence of trans-national organizations, such as the Indonesian Muslim Student Action Union (KAMMI, Campus Propagation Institute (LDK, Hizbut Tahrir (HT, and Wahdah Islamiyah (WI. Those organizations adopt fundamentalists thought who want purification of Islam, and anti-tradition. Nationality thought adopted by these organizations is a country that imposes Islamic law and Establishes a state of Khilafah (HT. Nevertheless, most students at the Khairun University embrace cultural Islam, following the footsteps of their parents and Ternate society in general.

    2010-01-01

    The use of reliable evidence to evaluate health care interventions has gained strong support within the medical community and in the field of plastic surgery in particular. Evidence-based medicine aims to improve health care and reduce costs through the use of sound clinical evidence in evaluating treatments, procedures, and outcomes. The field is hardly new, however, and most trace its origins back to the work of Cochrane in the 1970s and Sackett in the 1990s. Though she wouldn't know it, Florence Nightingale was applying the concepts of evidence-based reform to the medical profession more than a century before. She used medical statistics to reveal the nature of infection in hospitals and on the battlefield. Moreover, Nightingale marshaled data and evidence to establish guidelines for health care reform. Tracing the origins of evidence-based medicine back to Nightingale underscores how critical this movement is to improving the quality and effectiveness of patient care today.

    Scientific evidence is an increasingly important driver of social and environmental policy concerning child health. This trend began earlier than generally recognized. The child labor reform movement of the Gilded Age and early Progressive Era reflected not only moral and economic forces but also the dramatic advances during the later decades of the 19th century in scientific knowledge concerning children's biological and psychological vulnerability to environmental and psychosocial stressors. The growing importance of scientific information in shaping policy concerning children's health between 1870 and 1900 is illustrated by the events leading up to and following the New York State Child Labor Law of 1886. Child labor reform during this period was a critical step in the development of a science-based as well as a value-driven movement to protect children's environmental health and well-being that continues today.

  20. Social-movement analysis of the American antinuclear movement

    Ladd, A.E.

    1981-01-01

    Utilizing data from a survey of participants at the May 6, 1979 antinuclear rally in Washington, DC (N = 420), this dissertation explored some of the major structural and ideological characteristics of the American Antinuclear Movement. By organizing the data around three of the key analytical concepts in the study of social movements - mobilization, recruitment, and ideology - the author was able to derive from the demonstration sample a descriptive and illustrative analysis of those individuals, organizations, and processes involved in the national antinuclear crusade. Given that few researchers have actively studied the antinuclear movement beyond the scope of local or regional protests, this work constitutes the only empirical study to date examining a cross section of the movement's participants from a sociological perspective. It is also one of the few attempts to use a national demonstration as a social laboratory for the study of a social movement in general. In terms of the mobilization variables examined in the study, it was found that organizational networks, past movement activism, and individual resources were important factors in the May 6 mobilization effort. While less than one-half of the demonstrators were part of the antinuclear organizational network per se, most of them had been active in the major protest movements of the 1960's and 1970's. The demonstrators were relatively high in socio-economic resources and had occupational or educational schedules conducive to creating the necessary discretionary time for movement participation

  1. LAND REFORM IN UKRAINE: HISTORIOGRAPHICAL ANALYSIS

    Full Text Available Modern land reform, that continues in Ukraine since the beginning of the 90-th of ХХ century, is a logical result of the functioning of society and the state.. It’s prerequisites becames, especially full monopolization of state on ownership of land; absence of payment for land as one of the means of ensuring the rational use of lands; absence on workers motivation for intensive work on the land, etc.. These and other preconditions contributed to soil degradation, production of agricultural products with exceeding of maximum allowable concentrations of pollutants, development of diseases, undermine the gene pool of nature and man. Mentioned reasons determined the goal and objectives of modern land reform, which were originally set out in the preamble to the Resolution of the Verkhovna Rada of Ukraine from December 18, 1990 «On Land Reform» with following changes and additions, and in the implementation of the land-reformation measures gained more complete content. Conducted analysis shows that land reform in Ukraine leads to a change of ownership of land, contributes to solving problems of citizens by land plots, enactment of payment for land usecreation of conditions for the development of land market. Thus changing land relations, is formed legal and regulatory framework of land reform and land market. However, positive developments in the implementation of land reform to end of the 90-th years have not led to a radical and effective upgrade of agricultural production, recovery of investment processes in other branches of industry, improving of welfare of the population. Land reform measures didn’t receive adequate financial support. The ultimate goal - an economically-effective and environmentally safe use of land in Ukraine - has not been achieved. Further reforming of land relations contributed to the adoption in October 2001 of the Land Code of Ukraine in the new edition that created the legal principles of land reform. Since it

    Partridge, J.W. Jr.

    1993-01-01

    Federal Energy Regulatory Commission (FERC) Orders 436, 500, and 636, the Clean Air Act Amendments of 1990, Public Utility Holding Company Act reform, and the 1992 Energy Policy Act all can have significant effects on an LDC's operations. Such changes in an LDC's environments must be balanced by changes within the utility, its marketplace, and its state regulatory environment. The question is where to start. For Columbia Gas Distribution Cos., based in Columbus, OH, the new operating foundation begins with each employee. Internal strength is critical in designing initiatives that meet the needs of the marketplace and are well-received by regulators. Employees must understand not only the regulatory environment in which the LDC operates, but also how their work contributes to a positive regulatory relationship. To achieve this, Columbia initiated the COntinuing Regulatory Education program, or CORE, in 1991. CORE is a regulatory-focused, information-initiative program coordinated by Columbia's Regulatory Policy, Planning, and Government Affairs Department. The CORE programs can take many forms, such as emerging issue discussions, dialogues with regulators and key parties, updates on regulatory fillings, regulatory policy meetings, and formal training classes. The speakers and discussion facilitators can range from human resource department trainers to senior officers, from regulatory department staff members to external experts, or from state commissioners to executives from other LDCs. The goals of CORE initiatives are to: Support a professional level of regulatory expertise through employee participation in well-developed regulatory programs presented by credible experts. Encourage a constructive state regulatory environment founded on communication and cooperation. CORE achieves these goals via five program levels: introductory basics, advanced learning, professional expertise, crossfunctional dialogues, and external idea exchanges

  5. Improvements of reforming performance of a nuclear heated steam reforming process

    International Nuclear Information System (INIS)

    Hada, Kazuhiko

    1996-10-01

    Performance of an energy production process by utilizing high temperature nuclear process heat was not competitive to that by utilizing non-nuclear process heat, especially fossil-fired process heat due to its less favorable chemical reaction conditions. Less favorable conditions are because a temperature of the nuclear generated heat is around 950degC and the heat transferring fluid is the helium gas pressurized at around 4 MPa. Improvements of reforming performance of nuclear heated steam reforming process were proposed in the present report. The steam reforming process, one of hydrogen production processes, has the possibility to be industrialized as a nuclear heated process as early as expected, and technical solutions to resolve issues for coupling an HTGR with the steam reforming system are applicable to other nuclear-heated hydrogen production systems. The improvements are as follows: As for the steam reformer, (1) increase in heat input to process gas by applying a bayonet type of reformer tubes and so on, (2) increase in reforming temperature by enhancing heat transfer rate by the use of combined promoters of orifice baffles, cylindrical thermal radiation pipes and other proposal, and (3) increase in conversion rate of methane to hydrogen by optimizing chemical compositions of feed process gas. Regarding system arrangement, a steam generator and superheater are set in the helium loop as downstream coolers of the steam reformer, so as to effectively utilize the residual nuclear heat for generating feed steam. The improvements are estimated to achieve the hydrogen production rate of approximately 3800 STP-m 3 /h for the heat source of 10 MW and therefore will provide the potential competitiveness to a fossil-fired steam reforming process. Those improvements also provide the compactness of reformer tubes, giving the applicability of seamless tubes. (J.P.N.)

    Memory is critical to understanding animal movement but has proven challenging to study. Advances in animal tracking technology, theoretical movement models and cognitive sciences have facilitated research in each of these fields, but also created a need for synthetic examination of the linkages between memory and animal movement. Here, we draw together research from several disciplines to understand the relationship between animal memory and movement processes. First, we frame the problem in terms of the characteristics, costs and benefits of memory as outlined in psychology and neuroscience. Next, we provide an overview of the theories and conceptual frameworks that have emerged from behavioural ecology and animal cognition. Third, we turn to movement ecology and summarise recent, rapid developments in the types and quantities of available movement data, and in the statistical measures applicable to such data. Fourth, we discuss the advantages and interrelationships of diverse modelling approaches that have been used to explore the memory-movement interface. Finally, we outline key research challenges for the memory and movement communities, focusing on data needs and mathematical and computational challenges. We conclude with a roadmap for future work in this area, outlining axes along which focused research should yield rapid progress. © 2013 John Wiley & Sons Ltd/CNRS.

  11. Opportunities in Reform: Bioethics and Mental Health Ethics.

    Williams, Arthur Robin

    2016-05-01

    Last year marks the first year of implementation for both the Patient Protection and Affordable Care Act and the Mental Health Parity and Addiction Equity Act in the United States. As a result, healthcare reform is moving in the direction of integrating care for physical and mental illness, nudging clinicians to consider medical and psychiatric comorbidity as the expectation rather than the exception. Understanding the intersections of physical and mental illness with autonomy and self-determination in a system realigning its values so fundamentally therefore becomes a top priority for clinicians. Yet Bioethics has missed opportunities to help guide clinicians through one of medicine's most ethically rich and challenging fields. Bioethics' distancing from mental illness is perhaps best explained by two overarching themes: 1) An intrinsic opposition between approaches to personhood rooted in Bioethics' early efforts to protect the competent individual from abuses in the research setting; and 2) Structural forces, such as deinstitutionalization, the Patient Rights Movement, and managed care. These two themes help explain Bioethics' relationship to mental health ethics and may also guide opportunities for rapprochement. The potential role for Bioethics may have the greatest implications for international human rights if bioethicists can re-energize an understanding of autonomy as not only free from abusive intrusions but also with rights to treatment and other fundamental necessities for restoring freedom of choice and self-determination. Bioethics thus has a great opportunity amid healthcare reform to strengthen the important role of the virtuous and humanistic care provider. © 2015 John Wiley & Sons Ltd.

  13. Tort reform: an issue for nurse practitioners.

    2004-02-01

    To inform nurse practitioners (NPs) about the issues related to tort reform and its relationship to malpractice insurance costs. Current journals, newspapers, professional newsletters, and Internet sites. NPs are paying more for their malpractice premiums, and many are losing their places of employment as clinics close due to the increased cost of premiums. One method proposed for curbing the flow of monies spent on premiums and litigation is tort law reform. California serves as an example; its Medical Injury Compensation Reform Act (MICRA) tort reform law was passed 25 years ago, and it has maintained stable malpractice premiums. Other states have proposed similar laws, but some have not had similar success. To curb litigation costs, not only should tort laws be reformed, but NPs and physicians should keep abreast of current practice standards in order to provide quality medical care. Like physicians, NPs are affected directly by tort laws. These laws hold NPs accountable at the same level as physicians. In addition, many states limit NPs' practice to delegation of authority by a physician. Liability is therefore transferred from the NP to the physician and vice versa in cases of injury or wrongful act. In addition, many NPs are finding it increasingly difficult to locate insurers who will write policies for medical liability.

  14. Global implications of China's healthcare reform.

    The ongoing healthcare reform in China has a powerful spillover effect beyond the health sector and the borders of China. A successful completion of the Chinese reform will offer a new model for social justice development, shift the global economy toward sustainability and create a new hub for science and technology in medical and health science. However, reforming the healthcare system in the most populated country is a daunting task. China will not live up to its promise, and all the potentials may end with hype not hope if coherent national strategies are not constructed and state-of-the-art navigation is not achieved with staggering domestic and global challenges. The cost of failure will be immensely high, socioeconomic costs for Chinese and an opportunity cost for the world as a whole. A full appreciation of the global implications of China's healthcare reform is crucial in keeping China receptive toward good practices evidence-approved elsewhere and open minded to fulfill its international obligations. More critically, the appreciation yields constructive engagements from global community toward a joint development and global prosperity. The current report provides a multiple disciplinary assessment on the global implications of the healthcare reform in China. Copyright © 2014 John Wiley & Sons, Ltd.

  15. The ecological movement in France

    International Nuclear Information System (INIS)

    Taccoen, L.B.C.

    1977-01-01

    The anti-nuclear movements in France are part of a broader movement which, following common usage, the author calls the Ecological Movement. In France, the movement can be divided into a fairly small politically oriented core, numerous and varied associations for the defence of the environment, and a number of consumer associations. The movement cannot be classified politically, which accounts for the attitude of the political parties - distrust of the ''ecologists'', but considerable interest in them as voters. Those with responsibility for power generation must explain to the population at large the energy problem and the importance of economic growth in raising wages and reducing unemployment. They must also explain why nuclear power generation is one of the safest technologies existing at present. (author)

  16. On Biometrics With Eye Movements.

    2017-09-01

    Eye movements are a relatively novel data source for biometric identification. When video cameras applied to eye tracking become smaller and more efficient, this data source could offer interesting opportunities for the development of eye movement biometrics. In this paper, we study primarily biometric identification as seen as a classification task of multiple classes, and secondarily biometric verification considered as binary classification. Our research is based on the saccadic eye movement signal measurements from 109 young subjects. In order to test the data measured, we use a procedure of biometric identification according to the one-versus-one (subject) principle. In a development from our previous research, which also involved biometric verification based on saccadic eye movements, we now apply another eye movement tracker device with a higher sampling frequency of 250 Hz. The results obtained are good, with correct identification rates at 80-90% at their best.

  17. Eye movement perimetry in glaucoma.

    Trope, G E; Eizenman, M; Coyle, E

    1989-08-01

    Present-day computerized perimetry is often inaccurate and unreliable owing to the need to maintain central fixation over long periods while repressing the normal response to presentation of peripheral stimuli. We tested a new method of perimetry that does not require prolonged central fixation. During this test eye movements were encouraged on presentation of a peripheral target. Twenty-three eyes were studied with an Octopus perimeter, with a technician monitoring eye movements. The sensitivity was 100% and the specificity 23%. The low specificity was due to the technician's inability to accurately monitor small eye movements in the central 6 degrees field. If small eye movements are monitored accurately with an eye tracker, eye movement perimetry could become an alternative method to standard perimetry.

    2015-07-01

    This article traces significant moments in the history of the magazine Saúde em Debate - sourcing references and information from documents, historical studies, editions of the magazine, academic work and interviews with physicians and writers who contributed to its creation. In its 39 years of existence, although there may have been variations in the magazine's editorial policy, its role as a means for exchange of ideas and debate on critical health thinking, and making a contribution by in some way intervening in the Brazilian political process, has not changed. The magazine established itself with a firm reputation as a vehicle of scientific communication especially in the areas of health policy and management, expanding the scope of subjects over time. Among the challenges it has faced, as well as that of financial sustenance, has been its role as an instrument for dissemination of Latin American thinking in the field of health.

    Ciobanu, R.

    2012-01-01

    Full Text Available This paper presents a brief history of the financial reform designed by Nicolae Titulescu at the beginning of the 1920’s. His tax reform law was formulated after thorough research of other European tax systems. He tried to implement it while he was Minister of Finance. Even though the law was adopted, it was never enacted. It met a certain amount of controversy in the Assembly of Deputies. The analysis made also tries to explain the cedular tax system.

    2015-07-01

    From early twentieth century social reform movements emerged the ingredients for both child and family psychiatry. Both psychiatries that involve children, parents, and families began in child guidance clinics. Post-World War II intellectual creativity provided the epistemological framework for treating families. Eleven founders (1950-1969) led the development of family psychiatry. Child and family psychiatrists disagreed over the issues of individual and family group dynamics. Over the past 25 years the emerging sciences of interaction, in the context of the Primate Social Organ System (PSOS), have produced the evidence for the family being the entity of treatment in psychiatry.

  4. Progress in reforming chemical engineering education.

    Wankat, Phillip C

    2013-01-01

    Three successful historical reforms of chemical engineering education were the triumph of chemical engineering over industrial chemistry, the engineering science revolution, and Engineering Criteria 2000. Current attempts to change teaching methods have relied heavily on dissemination of the results of engineering-education research that show superior student learning with active learning methods. Although slow dissemination of education research results is probably a contributing cause to the slowness of reform, two other causes are likely much more significant. First, teaching is the primary interest of only approximately one-half of engineering faculty. Second, the vast majority of engineering faculty have no training in teaching, but trained professors are on average better teachers. Significant progress in reform will occur if organizations with leverage-National Science Foundation, through CAREER grants, and the Engineering Accreditation Commission of ABET-use that leverage to require faculty to be trained in pedagogy.

  5. Iliopsoas Tendon Reformation after Psoas Tendon Release

    2013-01-01

    Full Text Available Internal snapping hip syndrome, or psoas tendonitis, is a recognised cause of nonarthritic hip pain. The majority of patients are treated conservatively; however, occasionally patients require surgical intervention. The two surgical options for iliopsoas tendinopathy are step lengthening of the iliopsoas tendon or releasing the tendon at the lesser trochanter. Although unusual, refractory snapping usually occurs soon after tenotomy. We report a case of a 47-year-old active female with internal snapping and pain following an open psoas tenotomy. Postoperatively she was symptom free for 13 years. An MRI arthrogram revealed reformation of a pseudo iliopsoas tendon reinserting into the lesser trochanter. The pain and snapping resolved after repeat iliopsoas tendon release. Reformation of tendons is an uncommon sequela of tenotomies. However the lack of long-term studies makes it difficult to calculate prevalence rates. Tendon reformation should be included in the differential diagnosis of failed tenotomy procedures after a period of symptom relief.

  6. [The reform of Spanish abortion law].

    Requero Ibáñez, José Luís

    2009-01-01

    The article focuses on the different factors and circumstances that have led to the reform of Spanish Abortion Law (1985). Judicial investigations of several abortion clinics have demonstrated that up until today there has been a widespread tendency of the clinics to practice beyond the limits established by the law. Nonetheless, the reaction of the government has not been to protect the life of the unborn. Its reaction has been, however, to cover the irregularities committed by the abortionists through the legalization of their abusive practices. Besides, the reform of the law has been inspired by elements of radical feminism. The author points out the major reasons that make this reform unconstitutional and offers alternative solutions for the protection of the mother and the unborn child.

    2008-07-01

    The main contributions of this study are to conduct a comparative thermodynamic analysis of methane reforming reactions and to asses the influence of key operational variables on chemical equilibrium using an in-house code, developed in the open-source software Scilab{sup c} INRIA-ENPC (www.scilab.org). Equilibrium compositions are calculated by two distinct methods: evaluation of equilibrium constants and Lagrange multipliers. Both methods result in systems of non-linear algebraic equations, solved numerically using the Scilab function 'fsolve'. Comparison between experimental and simulated equilibrium data, published in the literature, was used to validate the simulated results. Effects of temperature, pressure, initial H{sub 2}O/CH{sub 4} ratio (steam reforming), initial CH{sub 4}:CO{sub 2}:N{sub 2} ratio (dry reforming) and initial O{sub 2}/CH{sub 4} ratio (partial oxidation) on the reaction products were evaluated.

  8. Design of a nuclear steam reforming plant

    Malherbe, J.

    1980-01-01

    The design of a plant for the steam reforming of methane using a High Temperature Reactor has been studied by CEA in connection with the G.E.G.N. This group of companies (CEA, GAZ DE FRANCE, CHARBONNAGES DE FRANCE, CREUSOT-LOIRE, NOVATOME) is in charge of studying the feasibility of the coal gasification process by using a nuclear reactor. The process is based on the hydrogenation of the coal in liquid phase with hydrogen produced by a methane steam reformer. The reformer plant is fed by a pipe of natural gas or SNG. The produced hydrogen feeds the gasification plant which could not be located on the same site. An intermediate hydrogen storage between the two plants could make the coupling more flexible. The gasification plant does not need a great deal of heat and this heat can be satisfied mostly by internal heat exchanges

    1997-01-01

    Terms of the policy and regulatory reform for the natural gas sector in Mexico since 1993 were described, and major changes taking place in the structure, organization and operations of the sector since the introduction of reforms were reviewed. Consequences that the structural changes are likely to have on the long-term balance of natural gas supply and demand in Mexico, have been assessed. The goal of full open access by November of 1997 was reiterated. Reforms to the electric power industry also have been undertaken. As with natural gas, the objective is to eliminate the State monopoly and to allow private power producers to participate in the expansion of the sector's generating capacity. Public investment will be directed towards the improvement of transmission and distribution networks. Over time, independent power producers are expected to become the principal source of funds for the expansion of electric power availability in Mexico. 3 tabs., 29 figs

    Nuclear damage compensation and energy reform were closely related. Nuclear damage compensation cost should be part of generation cost of nuclear power. Extend of nuclear damage compensation was limited by compensation standard of Tokyo Electric Power Co. (TEPCO) following guidelines of Dispute Reconciliation Committee for Nuclear Damage Compensation. TEPCO had already paid compensation of about two trillion yen until now, which was only a part of total damage compensation cost. TEPCO had been provided more than 3.4 trillion yen by Nuclear Damage Liability Facilitation Cooperation, which would be put back by nuclear operators including TEPCO. TEPCO could obtain present raising funds and try to reconstruct business with restart of nuclear power, which might disturb energy reform. Present nuclear damage compensation scheme had better be reformed with learning more from Minamata disease case in Japan. (T. Tanaka)

  12. Health insurance reform: labor versus health perspectives.

    Science.gov (United States)

    Ammar, Walid; Awar, May

    2012-01-01

    The Ministry of Labor (MOL) has submitted to the Council of Ministers a social security reform plan. The Ministry of Public Health (MOPH) considers that health financing should be dealt with as part of a more comprehensive health reform plan that falls under its prerogatives. While a virulent political discussion is taking place, major stakeholders' inputs are very limited and civil society is totally put away from the whole policy making process. The role of the media is restricted to reproducing political disputes, without meaningful substantive debate. This paper discusses health insurance reform from labor market as well as public health perspectives, and aims at launching a serious public debate on this crucial issue that touches the life of every citizen.

  14. Multi-fuel reformers for fuel cells used in transportation. Phase 1: Multi-fuel reformers

    Science.gov (United States)

    1994-05-01

    DOE has established the goal, through the Fuel Cells in Transportation Program, of fostering the rapid development and commercialization of fuel cells as economic competitors for the internal combustion engine. Central to this goal is a safe feasible means of supplying hydrogen of the required purity to the vehicular fuel cell system. Two basic strategies are being considered: (1) on-board fuel processing whereby alternative fuels such as methanol, ethanol or natural gas stored on the vehicle undergo reformation and subsequent processing to produce hydrogen, and (2) on-board storage of pure hydrogen provided by stationary fuel processing plants. This report analyzes fuel processor technologies, types of fuel and fuel cell options for on-board reformation. As the Phase 1 of a multi-phased program to develop a prototype multi-fuel reformer system for a fuel cell powered vehicle, the objective of this program was to evaluate the feasibility of a multi-fuel reformer concept and to select a reforming technology for further development in the Phase 2 program, with the ultimate goal of integration with a DOE-designated fuel cell and vehicle configuration. The basic reformer processes examined in this study included catalytic steam reforming (SR), non-catalytic partial oxidation (POX) and catalytic partial oxidation (also known as Autothermal Reforming, or ATR). Fuels under consideration in this study included methanol, ethanol, and natural gas. A systematic evaluation of reforming technologies, fuels, and transportation fuel cell applications was conducted for the purpose of selecting a suitable multi-fuel processor for further development and demonstration in a transportation application.

    2002-10-15

    Movement disorders are well known features of some dominant hereditary ataxias (HA), specially SCA3/Machado-Joseph disease and dentatorubropallidolusyan atrophy. However, little is known about the existence and classification of movement disorders in other dominant and recessive ataxias. We prospectively studied the presence of movement disorders in patients referred for HA over the last 3 years. Only those patients with a confirmed family history of ataxia were included. We studied 84 cases of HA, including 46 cases of recessive and 38 cases of dominant HA. Thirty out of 46 cases of recessive HA could be classified as: Friedreich ataxia (FA), 29 cases; vitamin E deficiency, 1 case. Twenty-three out of 38 cases of dominant HA could be classified as: SCA 2, 4 cases; SCA 3, 8 cases; SCA 6, 4 cases; SCA 7, 6 cases and SCA 8, 1 case. We observed movement disorders in 20/38 (52%) patients with dominant HA and 25/46 (54%) cases with recessive HA, including 16 patients (16/29) with FA. In general, postural tremor was the most frequent observed movement disorder (27 cases), followed by dystonia (22 cases). Five patients had akinetic rigid syndrome, and in 13 cases, several movement disorders coexisted. Movement disorders are frequent findings in HA, not only in dominant HA but also in recessive HA.

  16. Does the cerebellum initiate movement?

    Thach, W T

    2014-02-01

    Opinion is divided on what the exact function of the cerebellum is. Experiments are summarized that support the following views: (1) the cerebellum is a combiner of multiple movement factors; (2) it contains anatomically fixed permanent focal representation of individual body parts (muscles and segments) and movement modes (e.g., vestibular driven vs. cognitive driven); (3) it contains flexible changing representations/memory of physical properties of the body parts including muscle strength, segment inertia, joint viscosity, and segmental interaction torques (dynamics); (4) it contains mechanisms for learning and storage of the properties in item no. 3 through trial-and-error practice; (5) it provides for linkage of body parts, motor modes, and motordynamics via the parallel fiber system; (6) it combines and integrates the many factors so as to initiate coordinated movements of the many body parts; (7) it is thus enabled to play the unique role of initiating coordinated movements; and (8) this unique causative role is evidenced by the fact that: (a) electrical stimulation of the cerebellum can initiate compound coordinated movements; (b) in naturally initiated compound movements, cerebellar discharge precedes that in downstream target structures such as motor cerebral cortex; and (c) cerebellar ablation abolishes the natural production of compound movements in the awake alert individuals.

    The North American Free Trade Agreement (NAFTA) has had a significant effect on Mexico’s economy and institutions. The ongoing consideration of tax reform in Mexico requires an evaluation of the role of NAFTA in Mexico’s economy, including its tax structure; it also requires an assessment of the impact of the Mexico’s tax system on the trade and capital flows between Mexico and its NAFTA partners, the United States and Canada. Clearly, no good tax reform in Mexico can ignore the role of NAFTA...
