Abstract:

This article describes the dynamics of da‘wah movement of Salafis and their response to its stigmatization as being heretical and radical. The phenomenon of radical movements with their terrorist actions shapes the stigma of being radical to the Salafis. The spread and acceleration of the Salafi movement have put the da‘wah of the traditionalists in trouble. The stigma of Salafis as being radical and heretical results in the resistance against the Salafis to stop their da‘wah in many places. The stigmatization of the Salafis as being radical and intolerant drives the Salafis to show their identity as unidentical with the stigmatization. A number of persecution towards the Salafis is the implication of this stigma. This article is resulted from interviews with Salafi figures and d?‘?s who felt annoyed with the stigmatization. The appearance of Salafis which resembles those stigmatized as radicals lead to the emergence of public opinion that the Salafis are radical, while on the contrary, this article finds that the Salafis in fact fight against radical thoughts that lead to radical and terrorist actions.

Abstract:

ABSTRACTThe purpose of the present study is to evaluate the effect of thermal energy on the yield of and the bactericidal action of hydroxyl radical generated by photolysis of H2O2. Different concentrations of H2O2(250, 500, 750, and 1,000 mM) were irradiated with light-emitting diodes (LEDs) at a wavelength of 400 ± 20 nm at 25°C to generate hydroxyl radical. The 500 mM H2O2was irradiated with the LEDs at different temperatures (25, 35, 45, and 55°C). Electron spin resonance spin trapping analysis showed that the yield of hydroxyl radicals increased with the temperature, as well as the concentration of H2O2.Streptococcus mutansandEnterococcus faecaliswere used in the bactericidal assay. The LED-light irradiation of the bacterial suspensions in 500 mM H2O2at 25°C could hardly kill the bacteria within 3 min, while the bactericidal effect was markedly enhanced with the temperature rise. For instance, a temperature increase to 55°C resulted in >99.999% reduction of viable counts of both bacterial species only within 1 min. The photolysis of 500 mM H2O2at 55°C could reduce the viable counts of bacteria more efficiently than did the photolysis of 1,000 mM H2O2at 25°C, although the yields of hydroxyl radical were almost the same under the both conditions. These findings suggest that the thermal energy accelerates the generation of hydroxyl radical by photolysis of H2O2, which in turn results in a synergistic bactericidal effect of hydroxyl radical and thermal energy.

Full text

Abstract:

The kinetics of ring openings of a series of eight (trans-2-arylcyclopropyl)methyl radicals (1) were studied by indirect kinetic methods using Barton's PTOC esters as radical precursors and reaction with PhSeH as the competition reaction. The substituents were CF3, F, Me, and OMe located on both the para and meta positions of the aromatic ring. Syntheses of the radical precursors and the products of the radical reactions are described. Kinetics were determined between -43 and 25°C in four cases (CF3 and OMe substituents) and at 0 and 25°C in the other four cases. The rate constants at 25°C ranged from 1.0 × 1011 s-1 (p-CH3) to 4.1 × 1011 s-1 (p-CF3). The relatively large acceleration of the p-CF3 group, ca. 2.5 times as fast as the parent system with Ar = Ph, correlates well with Adam's ΔD substituent parameters but not with other radical substituent parameters. These calibrated radical rearrangements provide a new set of ultrafast reactions that can be applied in mechanistic probe studies.Key words: cyclopropylcarbinyl radical, kinetics, PTOC esters, benzeneselenol.

Abstract:

The field of free radical biology and medicine continues to move at a tremendous pace, with a constant flow of ground-breaking discoveries. The following collection of papers in this issue of Biochemical Society Transactions highlights several key areas of topical interest, including the crucial role of validated measurements of radicals and reactive oxygen species in underpinning nearly all research in the field, the important advances being made as a result of the overlap of free radical research with the reinvigorated field of lipidomics (driven in part by innovations in MS-based analysis), the acceleration of new insights into the role of oxidative protein modifications (particularly to cysteine residues) in modulating cell signalling, and the effects of free radicals on the functions of mitochondria, extracellular matrix and the immune system. In the present article, we provide a brief overview of these research areas, but, throughout this discussion, it must be remembered that it is the availability of reliable analytical methodologies that will be a key factor in facilitating continuing developments in this exciting research area.

Abstract:

This study addresses past, current and future development of the wind electrical power industry, that began prior to 1890 in Cleveland, Ohio and Askov, Denmark. Overcoming technological, business, societal and political hurdles required approximately 120 years of exploration to establish wind electricity generation as a radical innovation entering the acceleration stage of the industrial technology life cycle. Materials and integrated materials systems featuring mechanical, structural, fluid dynamic, electrical, electronic, and telecommunications functionality developed and introduced over that period have contributed uniquely to current commercial viability of wind turbine electrical power generation. Further growth and maturation is expected to continue to ≈ 2100, corresponding to a life cycle of ≅ 210 years. This finding has profound implications for radical innovation theory and practice, since historical analysis attributes a 50-60 year life cycle for 5 industrial revolutions, and emerging theory anticipates acceleration of radical innovation, as discussed in companion papers in this conference. Rapid growth in installed capacity of large scale wind turbines (>1MW) now positions wind electrical power generation in the Acceleration Stage, characterized by market competition between dominant wind turbine designs and societal acceptance by wind energy communities of practice in Europe, North America and Asia. Technical cost model based learning curve projections of Cost of Electricity (COE) suggest that by 2020 COE from wind will be competitive, without tax incentives, with electricity from conventional fossil and nuclear fuel sources. Capture by wind energy of up to 20% of the world electricity market appears likely by the end of the 21st Century.

Abstract:

Concomitant surgeries for unrelated diseases can be performed to minimize the risks associated with surgery and general anesthesia. In treating a male patient with breast cancer and severe coronary artery disease, we used the beating heart technique for a coronary artery bypass graft to avoid the negative effects of on-pump bypass on the possible acceleration of tumor growth. In this report, we present a unique case of concomitant off-pump coronary artery bypass graft surgery and modified radical mastectomy in a 56-year-old man.

Abstract:

Acceleration is a frequently recommended programming option for academically advanced students that enjoys considerable research support. Yet practitioners often object to acceleration on the grounds that it has negative effects upon students' social and emotional development. Research on affective outcomes of techniques such as grade advancement are mixed, containing reports of positive, negative, and neutral outcomes, and the role of gender and ethnicity is seldom explored. This study was undertaken to investigate the relationship between advanced grade placement and the self-concept of gifted students. Over 600 gifted adolescents completed the Self-Description Questionnaire-II (SDQII) and provided demographic information. Nearly 25% of the students were grade advanced, with Caucasian students being grade advanced significantly more often than Hispanic or African American students. No difference was found in any facet of self-concept between grade advanced and non-advanced students (and interactions of advanced status and gender and/or grade level). Readers are cautioned that the study was causal/comparative and not experimental in nature.

Full text

Abstract:

AbstractThe mechanistic rationalisation of specific ‘microwave effects’ previously reported in a range of chemical reactions suggests that they may be observable in the freeradical copolymerisation of comonomer pairs capable of forming donor-acceptor complexes. Polymerisation under microwave irradiation is carried out for several comonomer pairs with weak donor-acceptor interactions, and no acceleration in rate or change in degree of alternation attributable to changes in propagation are observed. An increase in reaction rate of 150–200 % is observed for all systems, with trends in molecular weight suggesting this was due to an increase in radical flux. This is consistent with earlier reports of rate enhancement for free-radical polymerisations using the initiator 2,2′-azobis-isobutyronitrile, and it is proposed that microwave irradiation may reduce the amount of geminate radical recombination.

Abstract:

Sulfate radical-based advanced oxidation processes have had considerable attention due to the highly oxidizing function of sulfate radicals (SO4−·) resulting in acceleration of organic pollutants degradation in aqueous environments. A Co-Ni mixed oxide nanocatalyst, which was prepared by the sol-gel method, was employed to activate peroxymonosulfate (PMS, HSO5−) to produce SO4−· with Acid Orange 7 (AO7) selected as a radical probe. The catalyst was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FT-IR) and transmission electron microscopy (TEM). The characterization results indicated that the ingredient of the catalyst had been changed and the amount of surface hydroxyl increased significantly with the addition of Ni. Therefore, it proved that Co-NiOx catalyst was more effective than CoOx to activate PMS. Moreover, ultrasound (US) can increase the degradation rate of AO7 and US/Co-NiOx/PMS system. This study also focused on some synthesis parameters and the system reached the maximum efficiency under the condition when [PMS] = 0.4 mM, [catalyst] = 0.28 g/L, Pus = 200 W. The AO7 removal in these systems follows first order kinetics. Last but not least, quenching studies was conducted which indicated that the amount of hydroxyl radicals (·OH) increases with the increase of initial pH and SO4−· was the primary reactive oxidant for AO7 degradation.

Abstract:

Philosophical and anthropological explorations of the state of modern culture testify to its crisis nature, connected with the acceleration of the processes of radical change of civilizational type of development. The need for a radical reform of the foundations of the future existence of society becomes evident. Lack of understanding of the real means of such reformation leads to the total disregard for the possibilities of the mind. One of its manifestations is the rapid growth of new and unconventional religions and occult-mystical currents; significant revival of the "secondary" myth-making (in particular, naturalistic, socio-technical); the spread of quasi-religious beliefs and infidelities; overall growth of mystical moods. The study of this aspect of the crisis of modern civilization is an urgent philosophical, religious, cultural and cultural problem.

Abstract:

The Anthropocene, viewed as a new geological epoch displacing the Holocene epoch of the last 10,000 to 12,000 years, represents what has been called an "anthropogenic rift" in the history of the planet.… Recent scientific evidence suggests that the period from around 1950 on exhibits a major spike, marking a Great Acceleration in human impacts on the environment, with the most dramatic stratigraphic trace of the anthropogenic rift to be found in fallout radionuclides from nuclear weapons testing.… Viewed in this way, the Anthropocene can be seen as corresponding roughly to the rise of the modern environmental movement, which had its beginnings in the protests led by scientists against above-ground nuclear testing after the Second World War, and was to emerge as a wider movement following the publication of Rachel Carson's Silent Spring in 1962. Carson's book was soon followed in the 1960s by the very first warnings, by Soviet and U.S. scientists, of accelerated and irreversible global warming. It is this dialectical interrelation between the acceleration into the Anthropocene and the acceleration of a radical environmentalist imperative in response that constitutes the central theme of Ian Angus's marvelous new book.Click here to purchase a PDF version of this article at the Monthly Review website.

Full text

Abstract:

The traditional adaptive cruise control system generally requires 25–40 km/h velocity to function. Moreover, the adaptive cruise control system cannot decelerate to the stop state, cannot adjust for stationary objects, and has limited scope of application. This study achieved the traffic jam tracking function of vehicles through the simultaneous use of millimeter wave and laser sensors and the analysis of the driving behavior of skilled drivers. The spacing and acceleration control of a vehicle is optimized based on the premise of ensuring safety and comfort by providing smooth, comfortable, safe, and radical control modes for driver selection, thereby increasing the probability that adaptive cruise control adopted by drivers. In addition, the collision avoidance function is added for safety reasons. Finally, actual vehicle experiments show that the distance and acceleration errors are in the expected range of errors of drivers. Moreover, the validity and practicability of the proposed adaptive cruise control algorithm are verified.

Abstract:

Applying industrial and market-driven logic has brought radical change to universities in the past few decades. Knowledge production and transmission as well as academics’ subjectivity have been substantially altered by neoliberal policies. This article introduces a social acceleration perspective and explores what happens to university teachers’ work practices in the face of increasing demands. The article draws on a study into the effect of social acceleration on a group of 15 professors in Brazil. Consequences include (a) producing ‘guilty subjects’ due to lack of time, (b) burnout from the feeling of ‘running uphill just to stay in place’, (c) an impact on work–life balance and retirement, (d) devaluing experience and expertise and (e) lack of identification with the work and workplace. The academics reported impossible demands on them, or even retiring. Reconciling their work practices with professional expectations generated a conflict of values: they no longer recognized themselves as good teachers, dedicated supervisors or innovative researchers. The article argues that the role of education is compromised by the accelerated university, which is transforming universities and academics into entrepreneurs in search of production.

Abstract:

A DFT study of the catalytic properties of CuO/CNT and CuO@CNT complexes for the heterogeneous catalytic ozonation has been performed. We illustrated the atomistic details of CuO/CNT and CuO@CNT with a quantitative and qualitative discussion within such an electronic structure characteristics. Ozone was catalytically decomposed into an atomic oxygen species and oxygen molecule on both the surface inner and outer CuO@CNT complex, while ozone can only decompose over CuO on the outer surface of CuO/CNT, with partial electrons transfer from CuO/CNT and CuO@CNT complexes to the adsorbate. Then the atomic oxygen reacted with the water molecule to form two hydroxyl groups on the surface, promoting the reaction chain for the generation of•OH which, in turn, lead to an increase in the catalytic ozonation efficiency. Results show synergetic confinement effect of metal oxide nanoparticles inside CNT could also lead to an acceleration of ozone decomposition and the generation of •OH on the inner and outer surface of carbon-nanotube containing catalytic particles.

Abstract:

It was found that sulfanylethanoic and 3-sulfanylpropanoic acids are effective regulators of molecular weight with chain transfer constants of 0.441 and 0.317, respectively, and show an unexpected acceleration effect on the radical polymerization of N-vinyl-2-pyrrolidone, initiated by 2,2’-azobisisobutyronitrile. It was determined for the first time that the thiolate anions of mercapto acids form a high-temperature redox initiating system with 2,2’-azobisisobutyronitrile during the radical polymerization of N-vinyl-2-pyrrolidone in 1,4-dioxane. Considering the peculiarities of initiation, a kinetic model of the polymerization of N-vinyl-2-pyrrolidone is proposed, and it is shown that the theoretical orders of the reaction rate, with respect to the monomer, initiator, and chain transfer agent, are 1, 0.75, 0.25, and are close to their experimentally determined values. Carboxyl-containing techelics of N-vinyl-2-pyrrolidone were synthesized so that it can slow down the release of the anticancer drug, doxorubicin, from aqueous solutions, which can find its application in the pharmacological field.

Abstract:

Abstract I discuss three tiers of technological innovation: mild innovation, or the acceleration by technology of a human activity aimed at a good; moderate innovation, or the obviation by technology of an activity aimed at a good; and radical innovation, or the altering by technology of the human condition so as to change what counts as a good. I argue that it is impossible to morally assess proposed innovations within any of these three tiers unless we rehabilitate a natural-law ethical framework. And I offer some moral starting points within such a framework, in connection with innovations of each of the three types.
