An unusual high total ozone value of 373 Dobson unit was observed over New Delhi on 25 March 1990. It is attributed to the leakage of stratospheric ozone into troposphere through tropopause break in association with a trough in mid-tropospheric westerlies with its axis lying along 82° E  longitude north of 20° N, at 300 hPa level.

Abstract. Biogenic very short-lived bromine (VSLBr) represents, nowadays, ~ 25 % of the total stratospheric bromine loading. Owing to their much shorter lifetime compared to anthropogenic long-lived bromine (LLBr, e.g., halons) and chlorine (LLCl, e.g., chlorofluorocarbons) substances, the impact of VSLBr on ozone peaks at the extratropical lowermost stratosphere, a key climatic and radiative atmospheric region. Here we present a modelling study of the evolution of stratospheric ozone and its chemical losses in extra-polar regions during the 21st century, under two different scenarios: considering and neglecting the additional stratospheric injection of 5 ppt biogenic VSLBr naturally released from the ocean. Our analysis shows that the inclusion of VSLBr result in a realistic stratospheric bromine loading and improves the quantitative 1980–2015 model-satellite agreement of total ozone column (TOC) in the mid-latitudes. We show that the overall ozone response to VSLBr within the mid-latitudes follows the stratospheric abundances evolution of long-lived inorganic chlorine and bromine throughout the 21st century. Additional ozone losses due to VSLBr are maximised during the present-day period (1990–2010), with TOC differences of −8 DU (−3 %) and −5.5 DU (−2 %) for the southern (SH-ML) and northern (NH-ML) mid-latitudes, respectively. Moreover, the projected TOC differences at the end of the 21st century are at least half of the values found for the present-day period. In the tropics, a small (

A male patient aged 43yrs. came to surgery OPD Majeedia Unani Hospital Jamia Hamdard New Delhi, in September 2018 with the complain of ulcer in the right foot posteriorly along the necrosis of Tendon Achilles. He was unable to walk a distance of about 100 meter due severe pain in the ulcer and calf muscle. limping on movement was very prominent. After required investigations and local examination of wounds, patient was planned and treated by local application, and combination of Unani Medicines formulations along with leech therapy as described in texts of Unani System of Medicine. With this Unani treatment non healing ulcer completely healed without any locomotor disturbances. The condition of leg totally resolved without any complications and side effects. Keywords: Non healing ulcer, Unani medicine, leech therapy.

The aims of this research are to (1) describe the types of language error which is done by the students who follow the BIPA program at Indonesian Embassy, New Delhi, India and (2) to elaborate the way to solve the language error problem which is done by the students who follow the BIPA program at Indonesian Embassy, New Delhi, India.  This research use case study method. The collecting data procedure in this research is done by using observation method.  The writer himself does the teaching program and the observation directly, then record the data.Based on the result of data analyses, it can be concluded that the types of language error which is done by the students of BIPA program in Indonesian Embassy, New Delhi India are (1) expressing error, (2) personal error, (3) group error, (4) analogy error, (5) teacher error. Besides, the students of BIPA program in Indonesian Embassy, New Delhi India make error on phonology, morphology, and syntax field. To solve those problems, the writer suggest that the teacher has to understand previously those student’s language errors, then allocating more time to give the proper comprehension to the students so that the language errors mentioned can be solved or at least can be minimalized.Moreover, to solve the student’s language error on phonological, morphological, and syntax, the writer suggest to the teacher to provide time or special class for especially learning grammar because commonly the learning modules or the materials of BIPA do not input the complete grammar material.This research contributes the important input to the BIPA teacher who will teach Indonesian language for Indian students. This research also to add the language knowledge especially in language error field.

Abstract. Using TOMS total-ozone measurements over high-altitude cloud locations and nearby paired clear locations, we describe the Clear-Cloudy Pairs (CCP) method for deriving tropical tropospheric ozone. The high-altitude clouds are identified by measured 380 nm reflectivities greater than 80% and Temperature Humidity InfraRed (THIR) measured cloud-top pressures less than 200 hPa. To account for locations without high-altitude clouds, we apply a zonal sine fitting to the stratospheric ozone derived from available cloudy points, resulting in a wave-one amplitude of about 4 DU. THIR data is unavailable after November 1984, so we extend the CCP method by using a reflectivity threshold of 90% to identify high-altitude clouds and remove the influence of high-reflectivity-but-low-altitude clouds with a lowpass frequency filter. We correct ozone retrieval errors associated with clouds, and ozone retrieval errors due to sun glint and aerosols. Comparing CCP results with Southern Hemisphere ADditional OZonesondes (SHADOZ) tropospheric ozone indicates that CCP tropospheric ozone and ozonesonde measurements are highly consistent. The most significant difference between CCP and ozonesonde tropospheric ozone can be explained by the low Total Ozone Mapping Spectrometer (TOMS) retrieval efficiency of ozone in the lower troposphere.

PurposeThis paper studies the role of heritage walks and tours in promoting inclusive education. It assesses if these walks are an effective method of exhibiting culture and facilitating inclusive heritage learning. The purpose of this paper is to attempt to establish that walks can play an imperative role in creating greater sensitivity towards heritage and conservation.Design/methodology/approachThe study uses a case study approach using mixed methods. Participants for qualitative interviews were chosen using purposive sampling and six interview schedules were sent to walk leaders. Walk participant data were collected through participant observation and standardised survey with randomly selected participants of the case walks. Surveys were sent to participants electronically.FindingsHeritage walks play a crucial role in not only imparting knowledge about history and heritage but also as a tool for learning other crucial skills, competencies, values, attitudes, etc. This paper attempts to highlight that walks are an effective and inclusive way to shed light on the alternative and forgotten stories. As an educational tool these walks can not only encourage the development of historical knowledge and appreciation but also assist in the development of competency to “de-construct” mainstream “grand narratives”, questioning and learning about the forgotten.Research limitations/implicationsThis paper has limited itself to the study of select cases in New Delhi. Since the study has followed a case study design, it does not produce a largely generalizable result, but rather examines and understands the dynamics of particular walks and produces insights that may well be applicable in other contexts. Whilst this paper makes an attempt to understand the changes in perception and attitudes, it does not study behavioural changes.Social implicationsIn the long run, walks allow for meaningful citizen engagement with tangible heritage such as monuments as well as intangible heritage such as practices and festivals. This allows for appreciation for the value of heritage resources and leads to a demand for better conservation and preservation from the authorities. In a few cases, local citizens themselves lead heritage management and development activities in a bid to promote their local culture. This paper has shown that heritage walks can be helpful tools in giving “forgotten” voices and stories recognition in contemporary society.Originality/valueAs heritage walks have recently gained popularity, there has been very limited research in the field especially linking heritage walks to heritage education. This is especially true for India. Even a city like New Delhi, which boasts of a robust heritage and is one of the tourism hubs of the country, heritage walks have been a very recent phenomenon. This research aims to address this lacuna in academic research and contribute meaningfully to the field of heritage education and conservation by studying how heritage walks support and promote inclusive heritage education.
