Projective tensor products and Apq spaces

The aim of this paper is to extend the notion of Apq space from its historical context in the work of Herz and to recognise such spaces as preduals of spaces of intertwining operators of induced representations as suggested by the work of Rieffel. This generalisation of Apq spaces involves considering projective tensor products of Lp spaces of Banach space-valued functions (the spaces of induced representations) and constructing a convolution of functions of such spaces. Sufficient conditions for the existence of the integral of the convolution are established. Most of this analysis depends upon an identity we derive of Radon-Nikodym derivatives of measures on homogeneous spaces involved. The elements of the generalised Apq space are shown to be cross-sections of a Banach semi-bundle over the double coset space corresponding to the groups from which the representations are induced, and their properties are duly discussed. In particular, the generalised form of the classical result Lp*Lq is a subset of Lr; where 1/r = 1/p + 1/q - 1; is shown to be true in this situation. The result that the Apq space is the predual of the space of intertwining operators is then established, under the condition that the intertwining operators can be approximated, in the ultraweak operator topology, by integral operators.Comment: 38 page

Economic Consequences of War: Evidence from Sri Lanka

We propose a theoretical and econometric framework to evaluate the impact of war on economic growth of a developing country with an open economy. The theoretical framework encompasses both the neoclassical and endogenous growth models. The econometric model is derived from the theoretical framework and an Autoregressive Distributed Lag framework is used for the estimation. We test this framework using Sri Lankan data. The war had significant and negative effects both in the short and long-run (annual average of 9% of GDP). High returns from investment in physical capital did not translate in sizable positive externalities. No significant effects of openness on growth in the long-run are found; however, effects are significant in the short- run. Inconsistent politically driven policies towards openness are the likely reason. As the ethnic conflict has finally come to an end, a policy framework with appropriate institutional reforms is needed for rapid growth and development.

HUMAN TRAFFICKING - PREVENTIVE INTERVENTIONS OF NGOs IN SOUTH INDIA

India is a country with rich traditions and unique culture. In such righ culture, women has been kept and treated with great respect and importance. Contradicting to the above dipiction, women has been the victims of humiliation, torture and explotiation from time immemorial. Sexual exploitation was one among them which never been discussed in the form of exploitation. Infact, prostitution has been in the society which had religious sanction too. During those time, the prostituted women were treated with great dignity as they were well qulified in various discipines. But when the institution like marriage and familiy become stronger, practice of prostituion took a commercial form where all types of rights were denyed to the women in sex trade. In such conditions, knowing the hardnes of the task, a very few number of NGOs have intervend in preventing women in sexual trade. A study was conducted to understand the types and quality of interventions considering 24 NGOs of South India. The study adopts descrptive and diagnostice research design and interview as tool to collect the data. Statustaical techniques such as discriptive statistics and contigency co-effeiciant test were adopted. The study reveals NGOs believes in prevention of the problem inspite of it being old practice. Counselling the vulnerable families a nd educating the society have been idnetified as a successful tool. The study also highlights different types of preventive activities adopted and also resons for not adopting preventive activies. The major reasons they quote is the obstacles from police department, goonds etc

X-Irradiation of DNA Components in the Solid State: Experimental and Computational Studies of Stabilized Radicals in Guanine Derivatives

Single crystals of sodium salt of guanosine dihydrate and 9 Ethyl Guanine were X-irradiated with the objective of identifying the radical products. Study with K-band EPR, ENDOR, and ENDOR-Induced EPR techniques indicated at least four radical species to appear in both crystals in the temperature range of 6K to room temperature. Three of these radicals (Radicals R1, R2, and R3) were present immediately after irradiation at 6K. Computational chemistry and EPR spectrum simulation methods were also used to assist in radical identifications. Radical R1, the product of net hydrogen addition to N7, and Radical R2, the product of electron loss from the parent molecule, were observed in both systems. Radical R3, in Na+.Guanosine-.2H2O, is the product of net hydrogen abstraction from C1\u27 of ribose group and radical R3 in 9EtG was left unassigned due to insufficient experimental data. Radical R4, the C8-H addition radical, was also detected in both systems. For Na+.Guanosine-.2H2O, R4 was observed after warming the irradiated crystals to the room temperature. But for the 9EtG crystals the corresponding radical form was detected after irradiation at room temperature. Density functional theory (DFT) based computational studies was conducted to investigate the radical formation mechanisms and their stability. Here possibilities of proton transfers from the neighboring molecules were considered. The first approach was to consider the proton affinities of the acceptor sites and deprotonation enthalpies of the donor sites. This approach supported the formation of radicals observed in both systems. The second approach, applied only to the 9EtG system, was based on proton transfers between 9EtG base-pair anion and cation radicals. Even though the charge and spins were localized as expected, the computed thermodynamic data predicted that the proton transfer processes are unfavorable for both anionic and cationic base-pairs. This indicates the need for additional work to draw final conclusions. In addition, DFT methods were used to compute the geometries and hyperfine coupling constants of 9EtG derived radicals in both single molecule and cluster models. The calculated results agreed well with the experimental results

Functional Anatomy of the Integument and Subcutaneous Structures of the Head, Neck and Thorax of the Domestic Turkey, Meleagris Gallopavo.

The microdissection of the integument and subcutaneous structures of the head, neck, and thorax of the Domestic Turkey, Meleagris gallopavo, revealed a complex system with several distinct layers of connective tissue, smooth and striated musculature, and fat bodies (corpora adiposa). These layers show structural variations across the body surface, and the patterns of variation of the different layers correlate with one another. The smooth apterial muscles and the striated subcutaneous muscles complement each other in moving certain feather tracts. Fat tissue is deposited in the dermis as dermal fat, in the Fascia superficialis, and in distinct fat bodies associated with the F. superficialis and the constrictor layer. This fat tissue does not function only as an energy storage place but also as structural fat with crucial biomechanical roles. This study provides a first step towards taking a holistic approach to the study of the integument and subcutaneous structures and their biomechanical, physiological and structural properties

Pregnancy outcome in elderly primigravida

Background: Incidence of elderly primigravida has increased now days, due to rising education level, effective means of birth control and high carrier goals. The women who conceived in advanced age more than 35 years for first time is defined as elderly primigravida. Indian standard is fixed at more than 30 years by Dutta 2013. These women are high risk for maternal and foetal complication and outcome. The study was done to assess pregnancy outcome in elderly primigravida.Methods: This is a prospective hospital-based study done from October 2016 to November 2018. Women of reproductive age group with first pregnancy admitted to department of obstetrics and gynaecology, Veer Surendra Sai Institute of Medical Science and Research, Burla were taken after exclusion criteria.Results: The incidence of elderly primigravida was 2.51%. But majority (84.76%) though married early, conceived late. Most of them are belongs to high socioeconomic group (62.86%). Anaemia was commonest complication (28.57%), fibroid in 5.71% cases. Pre-eclampsia (18.09%), eclampsia (3.81%), IUGR (12.38%) and twin pregnancies (5.72%) were seen more frequently than young primigravida. 55.24% were developed complications during labour like foetal distress (33.33%), PPH (3.81%) and retained placenta (2.86%). Gestational diabetes mellitus in (0.95%), caesarean section rate 29.52%, normal delivery 51.42%, and congenital anomaly 8.15%.Conclusions: Elderly primigravida are high-risk for several complications like spontaneous abortion, preterm labour, prolonged labour, foetal distress, high caesarean rate, PPH, congenital anomaly and increased incidence of perinatal mortality. Majority of this patients properly supervised are capable of safe and successful pregnancies ending in healthy mother and healthy baby

Dynamic equivalent of wind farm model for power system stability studies

A new dynamic equivalencing method for stability assessment of a grid-integrated wind farm is proposed in this article. The accuracy of the method is validated for a 34-bus system with 28-unit wind farm connected to Indian utility system. This wind farm consists of several wind turbines of two different ratings. The electrical parameters of the equivalent generator are derived from the mathematical model of the squirrel-cage induction generator. The parameters of the equivalent wind-turbine generator are optimized to yield minimum deviation from the detailed system response using genetic algorithm. The small-signal and transient stability responses of the study system with detail wind farm and equivalent model are simulated using MATLAB. Equivalent model eigenvalues are compared to the centre of inertia based detailed system eigenvalue. In addition, the computed eigenvalues and time-domain responses of the proposed equivalent model, detailed wind farm are compared against weighted model proposed earlier. In most of the investigated cases, the average error of dynamic responses between the proposed equivalent and detailed models are less when compared to weighted model. Thus, the large-signal responses of the proposed equivalent model show superior agreement with detailed system response
