When electrospinning has been used as a special technology of regenerative bone scaffold, for raising the efficiency of electrospinning and decreasing collecting area, the mechanism of bending instability was analyzed and concluded that the force of electric field is a key factor. Auxiliary gradient rings have been added to electric field, which changed the environment of electric filed. Then, it was verified that additive gradient rings could reduce the collecting area. On the other hand, Maxwell was used to analyze the strength and structure of electric field. The maximum intensity of electric field existed in the position of nozzle. The farther apart from nozzle, the rapidly intensity decreased. When auxiliary gradient rings had been added, the intensity of instability stage showed increased trend. Mechanism analysis and experimental result were confirmed by the simulation effectively.

Agni is termed as Vaishwanara as it takes the person from Mruthyuloka to Swargaloka. It is an important factor and is equitant to Prana; is one among Dashaprana Ayatana. Agni in Shareera is present in different forms with different actions. It is the responsible factor for both health and disease; on the other hand the successful outcome of treatment is also dependant on Agni. Chikitsa (treatment) is the process of bestowing normalcy which is either brought by Shodhana (purificatory) or Shamana (palliative) Karma. Snehapana is a pre-operative procedure for Shodhana Chikitsa where in Sneha Dravya (medicated fat) is administered for attainment of Upasthita Dosha Avastha and further ease in elimination of the vitiated Doshas. Assessment of Dosha, Dushya, Vyadhi Avastha, Roga Bala, Rogi Bala, Agni, Koshta etc. factors are essential for the attainment of Chikitsa Phala. Assessment of Agni not only helps in understanding Vyadhi but also enables to plan the dosage of Sneha to be administered. Thus this paper is an attempt to throw light on the importance of Agni, assessment of Agni and Agni Bala prior to Shodhananga Snehapana.

Key Factor

This chapter shows how the PRC’s search for greater status brought with it new obligations. China’s desire to stand at the helm of an Eastern revolution compelled the CCP to offer assistance to other Asian revolutionaries. The chapter argues that this mindset was a key factor in Beijing’s decisions to enter the Korean War and provide training and assistance to the Viet Minh. The United States, on the other hand, sought to prevent the PRC from gaining stature through its role in these conflicts. It often cited deflating China’s prestige in Asia as a motive for both fighting on in Korea and aiding the French in Indochina.

It was observed originally by Stark that a stream of mercury vapour allowed to distil away from the arc or glow discharge in vacuo remains luminous. It may be said to carry the luminosity away with it, and in the case of the arc discharge there is no difficulty in detecting the luminosity for 50 cm. or so from the source. Stark found that when a glow discharge was used, which developed the continuous band spectrum, this spectrum could be detected in the distilled vapour, along with the line spectrum. When the glow was passed through an electric field, the line spectrum was found to be quenched, leaving the band spectrum unaffected. The arc discharge, on the other hand, gave only the line spectrum in his experiments.

Microbubble floating in liquid dielectric and subjected to an electric field may initiate partial discharge (PD). This paper studies the parameters that affect the initiation through a computer simulation. This study inspects how the type of gas inside the microbubble, the size of the microbubble, distance from an electric field, Eo, source and, the magnitude of source’s voltage affect the start of PD. For a prolate spheroid shape, there is an important parameter called ‘c’. This ratio is between the radius of the microbubble polar (‘a’) and the radius of the equator (‘b’). At constant Eo and c, different gases will initiate PD at different distances from source due to differences in a localised electric field inside the microbubble (Emax). Emax is one of the important factors for PD initiation. It is interesting to report that if the ‘a’ and ‘b’ values are chosen so that ‘c’ will be constant, changes in Emax are insignificant. On the other hand, changes in ‘c’ will result in significant changes in Emax. Finally, changes in source’s voltage certainly affect the Emax.

This article explores a divergence of approaches applicable to interpretation of arbitration agreement due to the very nature of international commercial arbitration as transnational and multicultural forum. The author also considers globalization of international commerce as a key factor in promoting predictability and certainty of contractual interpretation and thereby promoting uniformity in its approaches. The interaction between the diversity of legal cultures, on the one hand, and demand for uniformity, on the other hand, are at stake in this discussion. Keywords: diversity, uniformity, arbitration agreement, interpretation, internationalcommercial arbitration, intention of the parties, validity, scope of arbitration agreement, national courts.

Protection Order

The increasingly ubiquitous use of smartphones is further complicating the legal response to domestic and family violence (‘DFV’). Perpetrators can now use smartphone recording facilities to record private conversations and activities of their (ex-)partners. Such behaviour may be a criminal offence of breach of a domestic and family violence protection order or stalking. On the other hand, those who have experienced DFV can record perpetrators and use the recordings in legal proceedings. The use of non-consensual smartphone recordings as evidence in DFV related cases is increasing and courts must determine when recordings are admissible. A key factor in making such determinations is whether the recording contravenes state-based criminal laws and listening and surveillance devices law. Drawing on reported experiences of the use of smartphone recordings in the context of DFV we show why further consideration and legal reform is needed if the law is to keep pace with this issue.

Abstract We investigate the Pc5 poleward moving auroral arc (PMAA) pulsations (~ 4–5 min period) using the ground-based all-sky imager network and the Time History of Events and Macroscale Interactions during Substorms (THEMIS) A, D, and E satellites, whose footprints were located near the PMAA in the post-midnight sector. The Pc5 PMAA pulsations considered herein occurred in conjunction with the enhancement of the magnetic and electric field oscillations observed near the equatorial plane of the magnetosphere. The magnetospheric oscillation signal displayed three-cycle oscillations, which correspond primarily to the PMAA pulsations. The value of coherence between the magnetospheric oscillations and the luminosity pulsations was higher than 0.9. Based on these observations, it is suggested that the PMAA pulsations and the magnetospheric field oscillations are initiated by the same physical mechanism and thus oscillate concurrently by the magnetosphere-ionosphere (M-I) coupling. The satellite data indicated a longer period of magnetospheric oscillations at the higher latitude site. On the other hand, the measured period of the PMAA pulsation was almost constant in the lower latitude region (~ 68.5°-70.0° MLAT), whereas in the higher latitude region (~ 70.0°-70.5° MLAT) it increased with increasing latitude. This signature demonstrates that the oscillations on the lower latitudinal side of the PMAA conformed with the monochromatic frequency field-line resonance (FLR) where the oscillation period was constant and independent of latitude, whereas the higher latitude side of the PMAA presented a multi-frequency FLR region where the period lengthened with increasing latitude. The Pc5 magnetic pulsations observed on the ground neither exhibited a clear coincidence with the PMAA pulsations nor with the magnetospheric magnetic oscillations. On the other hand, the H component of magnetic pulsations demonstrated a rather similar behavior to that of the ion pressure variation within the magnetosphere. The solar wind speed was significantly high, approximately 650 km/s, during this event. The magnetospheric magnetic and electric field oscillations could be triggered simultaneously in a wide region by an impulse such as rapid convection changes caused by the sudden variations of the interplanetary magnetic field (IMF) Bz, which was observed by the SuperDARN radar and the Geotail satellite.

Abstract The admissible closure conditions can be completely determined in the limit of vanishing cor­ relation length. In this case the Lundgren hierarchy can be solved, since this irregular state persists in the course of time. The electric field on the other hand loses its statistical character. - The results can be extended to examples of homogeneous turbulence with a finite correlation length.

Abstract An electric charge located outside a closed metal box does not produce an electric field inside the box. On the other hand, an electric charge located inside the box can generate an electric field outside the box. A charge inside the box can therefore exert a force on a charge outside the box, but not vice-versa, in apparent contradiction of Newton’s third law.

Societal Problems

The rise of polarization over the past 25 years has many Americans worried about the state of politics. This worry is understandable: Up to a point, polarization can help democracies, but when it becomes too vast, such that entire swaths of the population refuse to consider each other’s views, this thwarts democratic methods for solving societal problems. Given widespread polarization in America, what lies ahead? We describe two possible futures, each based on different sets of theory and evidence. On one hand, polarization may be on a self-reinforcing upward trajectory fueled by misperception and avoidance; on the other hand it may have recently reached the apex of its pendulum swing. We conclude that it is too early to know which future we are approaching, but that our ability to address misperceptions may be one key factor.
