Interannual Variability of Sea Surface Temperature in the Northern Indian Ocean Associated with ENSO and IOD

The Northern Indian Ocean （NIO） sea surface temperature （SST） warming, associated with the E1 Nifio/Southern Oscillations （ENSO） and the Indian Ocean Dipole （IOD） mode, is investigated using the International Comprehensive Ocean-Atmosphere Data Set （ICOADS） monthly data for the period 1979-2010. Statistical analy- ses are used to identify respective contribution from ENSO and IOD. The results indicate that the first NIO SST warming in September-November is associated with an IOD event, while the second NIO SST warming in spring-summer following the mature phase of ENSO is associated with an ENSO event. In the year that IOD co-occurred with ENSO, NIO SST warms twice, rising in the ENSO developing year and decay year. Both short- wave radiation and latent heat flux contribute to the NIO SST variation. The change in shortwave radiation is due to the change in cloudiness. A cloud-SST feedback plays an important role in NIO SST warming. The latent heat flux is related to the change in monsoonal wind. In the first NIO warming, the SST anomaly is mainly due to the change in the latent heat flux. In the second NIO warming, both factors are important.

Vacuum pyrolysis characteristics of waste epoxy printed circuit boards

Vacuum pyrolysis was employed to dispose scrap brominated epoxy printed circuit boards (PCBs).Pyrolysis characteristics of waste PCBs under normal pressure and vacuum were investigated in this paper.A detailed study on the analysis of the elemental composition of PCBs and the pyrolysis products was performed.The thermal decomposition kinetics was measured by a thermogravimetric (TG) analyzer.The activation energy of pyrolysis under nitrogen atmosphere and vacuum were 193 kJ/mol to 206 kJ/mol and 145 kJ/mol to 165 kJ/mol,respectively.The composition of materials was analyzed by elemental analyzer.The pyrolysis products were analyzed by GC (gas chromatograph),GC-MS (chromatography and mass spectrometry) and FT-IR (Fourier transform infrared spectroscopy).Vacuum helped to increase the yield of pyrolysis oil.The liquid yield of PCBs pyrolysis at 15 kPa and normal pressure were 31.3% and 23.5%,respectively.The main components in pyrolysis oils were phenol,isopropyl-phenol,and their brominated substitution.

A STUDY ON THE EFFECT OF SPRING INDIAN OCEAN SSTA ON SUMMER EXTREME PRECIPITATION EVENTS OVER THE EASTERN NW CHINA

Based on monthly mean wind,geopotential height,specific humidity,and surface pressure of NCAR/NCEP reanalysis,NOAA-reconstructed sea surface temperature (SST) of the Indian Ocean,and daily precipitation data at 97 meteorological stations over the eastern NW China in the past 47 years,the threshold values for extreme precipitation events (EPE) are defined using the percentile method.Singular Value Decomposition and synthetic analysis methods are used to analyze the relationship between summer EPE in the eastern NW China and SSTA in the preceding fall,winter,spring,and the concurrent summer.The result shows that preceding spring SST anomalies (SSTA) in the Indian Ocean are clear indicators for the forecast of summer EPE in the eastern NW China,and a key area of impact is located in the equatorial Indian Ocean.When spring SST is anomalously high in the equatorial Indian Ocean,the meridional circulation averaged over 100°E-110°E will be anomalously ascending near the equator but anomalously descending near 30°N in the middle and upper troposphere from the concurrent to the subsequent summer.In the meantime,the Southwest Monsoon from the Indian Ocean will be anomalously weak and there will be no anomalous water vapor transport to the eastern NW China,resulting in a lack of EPE in the subsequent summer,and vice versa.In addition,in response to anomalously high SST in the equatorial Indian Ocean in spring,the South Asia high pressure tends to be strong in the subsequent summer and more to the west.In the anomalously low SST year,however,the South Asia high tends to be weak in the subsequent summer and more to the east.This is another possible cause of the variation of summer EPE in the eastern NW China.

Diversity and Board Effectiveness： A Case of India

A number of research studies have dealt with the relationship between diversity and effectiveness of corporate boards. The present paper makes an attempt to provide an international perspective on diversity and effectiveness of corporate boards and examines such relationship in detail in the case of India. The paper presents the theory relating to diversity and board effectiveness with particular reference to women on boards. The position of diversity as related to the boards of National Stock Exchange （NSE） listed 511 companies and the 245 state-owned enterprises （SOEs） by the Government of India （GoI） is reflected in the paper. It then examines gender diversity specifically in the case of India and Singapore. Drawing from the evidence of diversity in the case of global companies, it offers the rationale for making boards global in composition and character. The paper highlights an interestiiag issue： whether the boards should have younger or veteran members？ This follows a discussion on diversity of boards in terms of skills, age, and personalities. Finally, the paper makes suggestions for balance boards to enhance their effectiveness and brings out lessons for the corporate organizations to promote diversity of their boards.

Sex Slavery in India： Unpacking the Stories of Trafficking Victims

While there is no consensus on the number of domestic sex trafficking victims in India, the phenomenon is estimated to be widespread and the evidence of its impact on victims is devastating. This paper explored the narratives of 10 sex trafficked women from a major non-government organization in New Delhi. Qualitative methodology was adopted and data were collected through open-ended unstructured interviews. The victimological paradigm including the Lifestyle Risk Model （LRM） by Van der Hoven and Maree provided the framework to discuss the key issues related to sex trafficking. Psychological experiences such as being abused by husbands, and in some cases, victims＇ own families; social conditions such as poverty and education; cultural practices such as vulnerability of women and marginalization; and lifestyle risk factors were observed throughout the stories of the victims. Furthermore, shame was found to be the core emotion in the stigmatization process. Limitations and future directions are also discussed.

The Role of Barrier Layer in Southeastern Arabian Sea During the Development of Positive Indian Ocean Dipole Events

Using data from Argo and simple ocean data assimilation (SODA), the role of the barrier layer (BL) in the southeastern Arabian Sea (SEAS: 60°E-75°E, 0°-10°N) is investigated during the development of positive Indian Ocean Dipole (IOD) events from 1960 to 2008. It is found that warmer sea surface temperature (SST) in the northern Indian Ocean appears in June in the SEAS. This warm SST accompanying anomalous southeastern wind persists for six months and a thicker BL and a corresponding thinner mixed layer in the SEAS contribute to the SST warming during the IOD formation period. The excessive precipitation during this period helps to form a thicker BL and a thinner mixed layer, resulting in a higher SST in the SEAS. Warm SST in the SEAS and cold SST to the southeast of the SEAS intensify the southeasterly anomaly in the tropical Indian Ocean, which transports more moisture to the SEAS, and then induces more precipitation there. The ocean-atmosphere interaction process among wind, precipitation, BL and SST is very important for the anomalous warming in the SEAS during the development of positive IOD events.

Incidents and Accidents in Plein Air Painting： One Path Towards Post-impressionism

A method for placing oil paint in metal tubes occurred in the early 1840s, which facilitated artists taking their materials out of doors to paint nature directly. In France in the 1860s, we know of painters like Claude Monet were working on beaches and port cities to capture the effect of scenes under natural light. By 1874 the Anonymous Society of Painters, Sculptors, Engravers, etc. （Impressionists） offered their first public exhibition to much criticism. A common complaint of the new work was that it lacked finish to be considered as a completed work for sale. It is the view of this paper that outdoor, or plein air painting, developed because of the circumstances this type of work developed in the artist naturally. I focus on two areas that outdoor painting forced the artist to consider： incidents and accidents. The incidents refer to the varied weather the painter had to deal with and the accidents identify the intuitive methods the plein air painters fell practice to when confronted by difficult passages or situations in nature. These experiences would shift the focus of the Impressionists from recording nature in a naturalistic way to self-expression, which would become a key idea in early modem painting. The finish the detractors of Impressionism called for would be replaced by an appreciation for the personal in painting as exacting images of landscape became predictable and lacked the vitality of the intuitive picture that could offer something new to art.

EFFECTS OF ENSO ON THE RELATIONSHIP BETWEEN IOD AND SUMMER RAINFALL IN CHINA

Based on the data of 1950 – 1999 monthly global SST from Hadley Center, NCAR/NCEP reanalysis data and rainfall over 160 weather stations in China, investigation is conducted into the difference of summer rainfall in China (hereafter referred to as the "CS rainfall") between the years with the Indian Ocean Dipole (IOD) occurring independently and those with IOD occurring along with ENSO so as to study the effects of El Ni?o - Southern Oscillation (ENSO) on the relationship between IOD and the CS rainfall. It is shown that CS rainfall will be more than normal in South China (centered in Hunan province) in the years of positive IOD occurring independently; the CS rainfall will be less (more) than normal in North China (Southeast China) in the years of positive IOD occurring together with ENSO. The effect of ENSO is offsetting (enhancing) the relationship between IOD and summer rainfall in Southwest China, the region joining the Yangtze River basin with the Huaihe River basin (hereafter referred to as the "Yangtze-Huaihe basin") and North China (Southeast China). The circulation field is also examined for preliminary causes of such an influence.

Athletes Who Sparkle： Stereotypes in the Televised Coverage of the 2010 Olympic Figure Skating Events

A vast amount of research has been devoted to gender roles in mass media. Prior studies relating to gender roles in media coverage of sports have been typically centered on underrepresentation, negative stereotypical portrayals of female athletes, and iconic heroic portrayals of male athletes. However, few studies have examined media coverage of male participation in so-called ＂gender inappropriate＂ sports. This research seeks to fill a gap in literature by exploring gender cues presented in the televised coverage of male and female figure skating events in the 2010 Winter Olympic Games. The findings from this research indicate that male athletes who cross gender barriers to participate in a feminine sport are likely to receive gender-marked stereotypical televised coverage. Much of the significant findings indicate that male figure skaters were visually and verbally portrayed as more feminine than the female figure skaters. The study opens lines of research into how sports are portrayed and could potentially influence sport marketing, athlete endorsements, athlete wardrobe, and other decisions made by the media, athletes, and individuals working in the sport industry.

Applying real time seismic monitoring technology for slope stability assessment—An Indian opencast coal mine perspective

This paper outlines the results obtained from real time microseismic monitoring of an opencast coal mine in South India.The objective of the study is to investigate the stress changes within the rockmass along the slope due to underground mine development operation and their impact on the stability of the highwall slope.The installed microseismic systems recorded the seismic triggerings down toà2 moment magnitude.In general,most of the events recorded during the monitoring period are weak in seismic energy.The study adopts a simple and more reliable tool to characterize the seismically active zone for assessing the stability of the highwall in real time.The impact of underground working on the slope is studied on the basis of the seismic event impact contours and seismic clusters.During the monitoring period,it is observed that the intensity of the overall microseismic activity along the slope due to the mine development operations did not cause any adverse impact on the highwall stability.

Graphic Characterization and Visual Narrative in The History of Little Goody Two-Shoes(1765)

Focusing on The History of Little Goody Two-Shoes(1765),John Newbery's longest and most famous work of children's fiction,this article offers a corrective to previous scholarship that has routinely overlooked the significance of woodcut illustrations to characterization and narrative construction in early children's fiction.Unlike most eighteenth-century fiction,illustration was integral to Newbery's children's books,conceived at the onset,not added as embellishment to later editions.Routinely described as too small to be important or reduced to discussions of didacticism and ideology only,the cheap woodcuts contained in eighteenth-century children's fiction enabled reader-viewers of differing literacy levels to comprehend and imaginatively take part in narratives.In Goody Two-Shoes,illustrations elaborate,specify,and extend characterizations of Margery,while also engendering a means of maintaining a child-centric tale for young audiences in the face of an ever-aging protagonist.This article demonstrates how woodcuts enable the reader-viewer to construct a narrative that extends beyond what is written.

Timing of the initial collision between the Indian and Asian continents

There exist three mainstream opinions regarding the timing of the initial collision between the Indian and Eurasian continents,namely,65±5,45±5,and 30±5 Ma.Five criteria are proposed for determining which tectonic event was related to the initial collision between India and Asia:the rapid decrease in the rate of plate motion,the cessation of magmatic activity originating from the subduction of oceanic crust,the end of sedimentation of oceanic facies,the occurrence of intracontinental deformation,and the exchange of sediments sourced from two continents.These criteria are used to constrain the nature of these tectonic events.It is proposed that the 65±5 Ma tectonic event is consistent with some of the criteria,but the upshot of this model is that the magmatic activity originating from the Tethyan subduction since the Mesozoic restarted along the southern margin of the Asian continent in this time after a brief calm,implying that the subduction of the Neotethys slab was still taking place.The magmatic activity that occurred along the southern margin of the Asian continent had a 7-Myr break during 72-65 Ma,which in this study is interpreted as having resulted from tectonic transformation from subduction to transform faulting,indicating that the convergence between the Indian and Asian continents was once dominated by strike-slip motion.The 30±5 Ma tectonic event resulted in the uplift of the Tibetan Plateau,which was related to the late stage of the convergence between these two continents,namely,a hard collision.The 45±5 Ma tectonic event is in accordance with most of the criteria,corresponding to the initial collision between these two continents.

Epidemiology of patients admitted to a major trauma centre in northern India

Objective： Trauma in India is an increasingly significant problem, particularly in light of rapid development and increasing motorization. Social changes are resulting in alterations in the epidemiology of trauma. The aim of the study was to assess the various epidemiological parameters that influence the cause of injury in the patients admitted to a major trauma centre in northem India. Methods： An observational study of 748 patients chosen by random assortment was carried out over a peri- od of 1 year （August 2008 to July 2009）. Age, sex, injury type and pattern were noted. Injury mode of upper and lower limbs was also noted. Results： Injuries occur predominately in the age group of 15-30 years. Males incurred more injury with male to female ratio of 6：1. The most vulnerable group was motorcycle users. Among the injured, farmers were the most commonly involved. Blunt injuries （94.92%） were much more common than penetrating injuries. Among patients with head injury, two wheelers related accidents were the most common （40.3%）. Most spinal cord injuries were caused by falls from height （51.09%）. Most lower limb fractures were simple type. Compound fractures of the lower limb were more common than up- per limb fractures. Conclusion： Strict enforcement of traffic rules, combined with improved infrastructure and behavior change can decrease the burden of road traffic accidents in India and other developing countries. This study could assist in raising the profile of road traffic accidents as a public health problem which needs to be addressed as a preventable cause of mortality and morbidity, and plan- ning appropriate interventions for this major challenge. Preventive strategies should be made on the basis of these epidemiological trends.

Change of Indonesian Throughflow outflow in response to East Asian Monsoon and ENSO activities since the Last Glacial

The Indonesian Throughflow （ITF） links upper ocean waters of the west Pacific and Indian Ocean, modulates heat and fresh water budgets between these oceans, and in turn plays an important role in global climate change. The climatic phenomena such as the East Asian monsoon and E1 Nifio-Southern Oscillation （ENSO） exert a strong influence on flux, water properties and vertical stratification of the ITF. This work studied sediments of Core SO 18462 that was retrieved from the outflow side of the ITF in the Timor Sea in order to investigate response of the ITF to monsoon and ENSO activities since the last glacial. Based on Mg/Ca ratios and oxygen isotopes in shells of planktonic foraminiferal surface and thermocline species, seawater temperatures and salinity of both surface and thermocline waters and vertical thermal gradient of the ITF outflow were recon- structed. Records of Core SO18462 were then compared with those from Core 3cBX that was recovered from the western Pa- cific warm pool （WPWP）. The results displayed that similar surface waters occurred in the Timor Sea and the WPWP during the last glacial. Since -16 ka, an apparent difference in surface waters between these two regions exists in salinity, indicated by much fresher waters in the Timor Sea than in the WPWP. In contrast, there is little change in difference of sea surface temper- atures （SSTs）. With regard to thermocline temperature （TT）, it increased until -11.5 ka since the last glacial, and then re- mained an overall unchanged trend in the WPWP but continuously decreased in the Timor Sea towards the late Holocene. Since ~6 ka, thermocline waters have tended to be close to each other in between the Timor Sea and the WPWP. It is indicated that intensified precipitation due to East Asian monsoon and possible ENSO cold phase significantly freshened surface waters over the Indonesian Seas, impeding the ITF surface flow and in turn having enhanced thermocline flow during the Holocene. Consequently, thermocline water of the ITF outflow was cooling and thermocline was shoaling towards the late Holocene. It is speculated that, in addition to strengthening of East Asian winter monsoon, increasing ENSO events during the late Holocene likely played an important role in influencing thermocline depth of the ITF outflow.
