Abstract: Displacement is one of the causes for migration of indigenous people to urban areas. This study was conducted among the Mising people of North Lakhimpur Town, the Headquarter of the Lakhimpur District, Assam, who have migrated as a result of displacement due to heavy riverbank erosion and flood. The study depicted that they are having problem in case of food, shelter, dress, education, health and gradually the traditional culture is eroded among them and all these stand as the great challenge in front of them.

A Multisensor Analysis of the Life Cycle of Bow Echo over Indian Region
Devajyoti Dutta,Diganta Kumar Sarma,Sanjay Sharma
International Journal of Atmospheric Sciences , 2014, DOI: 10.1155/2014/207064
Abstract: This study deals with the life cycle of bow echo events on October 24 and 26-27, 2006, from Doppler weather radar (DWR) observations supported by Radiosonde and National Centers for Environmental Prediction (NCEP). The cell bow echo (CBE) on October 24 evolved from two small isolated cells with radar reflectivity ≥40?dBZ. The vertical structure consists of one single mature cell with 20?dBZ echoes reaching up to 10?km while 40?dBZ echoes extended uniformly from ground to ~5?km height. The radial velocity shows a high value >?15?m/s towards the radar at the upper height (about 6 to 11?km); the lower height is predominant with velocity away from the radar (about 5 to 15?m/s). The squall line bow echo on October 26 and 27 has its origin over ocean and moved towards the radar site and decayed thereafter. The radar reflectivity pattern for this squall line showed it to be a trailing stratiform type squall line with length of ~200?km. The echo top height was more than 12?km in height. Strong inflow cases were observed from both radiosonde and radar. 1. Introduction The life cycle of mesoscale convective systems (MCSs) can be studied with the help of on-board IR and microwave sensors as well as ground based Doppler weather radar (DWR) [1]. Though the geostationary IR data is very useful for the study of evolution of MCSs because of its large areal coverage, it can give only the cloud top information but unable to give details inside of the system. On the other hand, DWR can give much better information of the MCS but their coverage is limited, where the reliable observation >200?km is restricted due to the refraction of the transmitted signal. The passive microwave radiometer cannot be used for the study of the evolution of MCSs as these are carried by polar satellite with low repetition. A multisensor approach is useful approach to study the multifaceted characteristics of MCSs. Till date many of the studies of MCSs are performed with the help of both active and passive sensors: evolution (e.g., [2–6]), size and structure [7, 8], and reflectivity structures (e.g., [9–12]). The severe weather events are mostly associated with the organized MCSs such as bow echoes and squall lines. Bow echoes were named and described in detail by Fujita [13]. A bow echo is defined as a nontransient bow or crescent shaped radar signature with a high reflectivity gradient on the convex edge. Most of the time, they are associated with severe weather. According to Fujita [13] the bow echo commonly evolves from either a single convective cell or a line of cells. Klimowsky et al.
Assessing Consistency of Consumer Confidence Data using Dynamic Latent Class Analysis
Sunil Kumar,Zakir Husain,Diganta Mukherjee
Quantitative Finance , 2015,
Abstract: In many countries information on expectations collected through consumer confidence surveys are used in macroeconomic policy formulation. Unfortunately, before doing so, the consistency of responses is often not taken into account, leading to biases creeping in and affecting the reliability of the indices hence created. This paper describes how latent class analysis may be used to check the consistency of responses and ensure a parsimonious questionnaire. In particular, we examine how temporal changes may be incorporated into the model. Our methodology is illustrated using three rounds of Consumer Confidence Survey (CCS) conducted by Reserve Bank of India (RBI).
Link Enhancer for Vehicular Wireless ATM Communications

Computer Science , 2008,
Abstract: Majority of the applications used in defense are voice, video and data oriented and has strict QoS requirements. One of the technologies that enabled this is Asynchronous Transfer Mode (ATM) networking. Traditional ATM networks are wired networks. But Tactical networks are meant to be mobile and this necessitates the use of radio relays for Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V) communications. ATM networks assume a physical link layer BER of 10^-9 or better because of the availability of reliable media like optical fiber links. But this assumption is no longer valid when ATM switches are connected through radio relay where error rates are in the rage of 10^-3. This paper presents the architecture of a Link Enhancer meant to improve the Bit Error Rate of the Wireless links used for V2I and V2V communications from 1 in 10^4 to 1 in 10^8
Education and Electoral Outcomes  [PDF]
Diganta Mukherjee, Rajlakshmi Mallik
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.22033
Abstract: This paper develops a model of the electoral process for analyzing the voters’ choice faced with two parties. A typical voter is concerned with both local governance issues and macro issues. The relative importance attached by a voter to local and macro concerns is governed by the level of education of the voter. The voter must exercise his choice based on two sets of information—the first pertains to the candidate’s efficiency level and the other pertains to the efficiency of the party as a whole. The model focuses on the case where the party with the better image has been forced to put up a less efficient candidate, as this is sufficient to analyse the trade-off involved. The model shows how the election out-comes may be influenced by the education level of the electorate and the design of election campaigns. This has implications for the design of education policy in the long run and measuring social efficiency of education.

Abstract: Background: Vector Control and Personal Protection measures practices play major role in control of malaria. Objective: The study objective was to find out the practices of mosquito control and personal protection measures observed at household level and the acceptance of vector control measures under malaria control programme. Methods: A Community based cross-sectional study was undertaken from June 2009 to May 2010 and 150 tribal and 150 non-tribal head of the households interviewed. Data was collected on socio-demographic characteristics, factors related to mosquito breeding and its prevention practice, personal protection measures, DDT spray status of their houses. Data was analyzed by Epi Info Version7. Results: The overall coverage of DDT was low (25.3%). Coverage was slightly better among tribal households (31.3%) compared to non-tribal population (19.4%). The acceptance of DDT spray was found to be significantly associated with knowledge about mode of transmission of malaria and type of house. Room-wise coverage was not as per norms. Refusal of DDT was seen more among non-tribal communities. Commercial personal protection practices like mosquito repellants, mats and coils were lesser among the tribal counter parts and it was associated with level of income. Majority of tribal and non-tribal respondents were not having knowledge of the new insecticide treated bed nets (ITNs) and LLINs. Conclusion: Coverage with IRS in rural areas is far less (25.3%) than the recommended coverage of 80% required for its effectiveness. With majority using mosquito nets in their houses, use of ITNs should be encouraged and IEC activities for creating greater awareness on methods to control vector population suggested for success of the malaria programme.

Abstract: The present paper focuses on the various disturbance agents such as coal mining, limestone extraction, stone quarrying, jhum cultivation, fire, grazing, over-exploitation of resources, road constructions etc., affecting the natural growth of Nepethes khasiana in the Nokrek Biosphere Reserve of India. N. khasiana is the prominent insectivorous scandent shrubs species of this biosphere reserve and is an important source of medicine and basic ornamental uses for the local garo tribal people of north-east India. The inevitable pressure due to commercialization of the N. khasiana is leading to severe destruction of the species and may create the scarcity of that species in the near future. Therefore, joint efforts need to be implemented by the local garo villagers with governmental and non-governmental agencies for conservation and sustainable use of N. khasiana. The government may also take initiative by allotting demarcated forests areas to the villagers as village forest, thus motivating the villagers to take special care for its protection and rehabilitation and for a sustainable output.

Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102999
Patients having chronic total occlusion (CTO) of coronary artery who have inadequate collaterals to provide sufficient blood flow to the myocardial bed may present with anginal symptoms. Revascularisation of myocardium can be considered in those patients who remain symptomatic despite optimal medical therapy. Angioplasty in CTO may lead to complication like coronary perforation which if not managed on time can be catastrophic. However with proper back up, team work and skill such dreaded complication can be taken care of with good outcome.
