Macro-scale matter wave generation in charged particle dynamics in a magnetic field, a consequence of quantum entanglement
No full textMatter wave interference effects on the macro-scale predicted by the author in charged particle dynamics in a magnetic field [R.K. Varma, Phys. Rev. E 64, 036608 (2001)], and observed subsequently [R.K. Varma, A.M. Punithavelu, S.B. Banerjee, Phys. Rev. E 65, 026503 (2002); R.K. Varma, S.B. Banerjee, Phys. Scr. 75, 19 (2007)] have been shown here to be an interesting consequence of quantum entanglement between the parallel and perpendicular degrees of freedom of the particle. Treating the problem in the framework of the inelastic scattering theory, it is shown that these macro-scale matter waves are generated in the ‘parallel’ degree of freedom as a modulation of the plane wave state of the particle along the field concomitantly with the excitation of Landau levels in the perpendicular degree of freedom in an inelastic scattering episode. We highlight here the role of quantum entanglement leading to the generation of this macro-scale quantum entity which has been shown to exhibit observable consequences. This case also exemplifies a situation exhibiting quantum entanglement on the macro-scale
Cointegration Analysis with State Space Models
No full textThis paper presents and exemplifies results developed for cointegration analysis with state space models by Bauer and Wagner in a series of papers. Unit root processes, cointegration and polynomial cointegration are defined. Based upon these definitions the major part of the paper discusses how state space models, which are equivalent to VARMA models, can be fruitfully employed for cointegration analysis. By means of detailing the cases most relevant for empirical applications, the I(1), MFI(1) and I(2) cases, a canonical representation is developed and thereafter some available statistical results are briefly mentioned.State space models, unit roots, cointegration, polynomial cointegration, pseudo maximum likelihood estimation, subspace algorithms

Air Pollution Control Equipment
No full textThis book has arisen directly from a course on Air and Water Pollution Control delivered by the first named author at the Technical University of Berlin. Extractions of this course have been presented in Brazil, Turkey and India. It was at the Indian Institute of Technology of Madras where the first named author got in contact with Professor Varma, who turned out to be a suggestive, cooperative coauthor. This book is addressed primarily to chemical, environmental and mechanical engineers, engaged in the design and operation of equipment for air pollution control. But it will certainly be helpful to chemists and physicists confronted with the solution of environmental problems. Furthermore it is intended as a text book for engineering courses on environmental protection. The goal of the book is the presentation of knowledge on design and operation of equipment applicable to the abatement of harmful emissions into air. The technology of air pollution control is of relatively young age, but it has already achieved a high degree of performance, due to the research and develop ment work invested in the last decades in this fiel

Maximizing the health benefits of lycopene isomers
No full textLycopene is an acyclic C40 non polar carotenoid found in tomatoes. In nature, the predominant form is the all-trans isomeric form which represents 80-97% of lycopene in tomato and tomato related products. However on consumption of tomato products, >50% of the lycopene is found in the cis isomeric form in the body, thereby implying that the cis isomeric form is the more bioavailable /bioactive form in the human body.
The major objective of our study was to validate the bioactivity of lycopene isomers. Three approaches were used to achieve this goal. 1). An ab initio computational model to study the structure of isomers. 2). Develop a method to isolate isomers. 3). Study antioxidant activity and cellular proliferation activity of isomers in in- vitro condition.
Computational modeling studies showed that lycopene isomers differ in their electronic distribution on the molecules. Cellular Antioxidant Activity (CAA) method showed that cis isomers have higher CAA compared to all-trans isomers.
The cellular proliferation assay known as the MTT assay indicated larger decrease in proliferation of cis isomer treated prostate cancer cells. The anti-inflammatory assay (measures the amount of nitric oxide (NO) produced by mouse macrophages (RAW 264.7)) showed marginal difference in activity between control and isomer treated cells.
Non-thermal processing techniques like High Hydrostatic Pressure (HHP) processing and Pulse Electric Field (PEF) were used to increase the yield of beneficial cis lycopene isomer in the processed product. The results showed an qualitative increase in cis isomer after non-thermal processing.
This study helps us get deeper insights on the activity of cis and all-trans lycopene isomers at a basic molecular level, which correlates to the activity at a chemical and biological level. Non-thermal processing methods like High Hydrostatic Pressure processing and Pulse Electric Field processing methods can cause lycopene isomerization. These can be used as alternative means of processing to get tomato products that can yield health benefits to the consumers.Ph.D.Includes bibliographical referencesby Supriya Varm

Living apart together: Intimate Relationship across nations distance:Transnational Couples: Gender, Spirituality and Digitalisation
No full textIn the past decades the time honoured assumption that intimate couples stay under the same roof has been challenged, diverse forms of living arrangements are emerging where partners maintain separate residences, even across national borders. However, investigation of intimate relationship formation and maintenance across geographical borders is rather limited. This ongoing research project explores relationship among distant transnational couples, i.e. couples who are residing/ have resided in different countries (minimum one year), at least one of the partners in the Scandinavian context. Within a theoretical framework of gender related to emotional reflexivity (Holmes, 2014), spirituality and digital emotions, the history and dynamics of these relationships are explored, in the backdrop of transnationalism. In-depth interviews (face- to face and some online) dealing with the psycho- social aspects of togetherness and separation, visions about the future and suggestions to other distant couples are conducted with 20 couples/partners. The preliminary results show the challenges entailed in distant intimacy dynamics and their negotiations. The interactional state of being together and apart mutually enable and constrain each other in many ways. Quality time together, ‘fun’ memories construction, parting rituals, ‘systematic’ online contact, spiritual acceptance emerge as the resources. While the mobility costs (economic, temporal and affective), restrictive migration laws, pressure to have quality time, work/ life segmentation, social network related dilemmas emerge as burdens. However, being apart and together are intertwined for the transnational distant couples. The analysed ‘good practices’ will form the applied part for promoting the mental health and wellbeing of such couples.
