Comparing Kaniyan Koothu (Dramatic Dance) art with Marxist Theory

The Marxist type of materialism is a sociological study based on historical context. These include family, property, state, caste, religion, rituals, art, literature, classes, and social divisions. In a world of biodiversity, the environment in which humans live is extensive. Only men can speak of trades, religions, and castes. When it is accepted that history is for men, riots arise within religion itself. There are divisions, and some communities are oppressed. The oppressed tribes find God through KalaikKoothu and identify their races. Man-made art and literature operate with various techniques. Man is the one who creates the world according to himself. Divisions and rifts arose in society. Society gave way to ups and downs

Small Scale Wind Generation System: Part I – Experimental Verification Of Flux Reversal Generator Block

This research work, titled Small Scale Wind Generation System, reported in part I and part II, proposes modeling, analysis and control of a small scale wind energy conversion system employing a direct driven Flux Reversal Generator (FRG) connected to the micro grid through a Quasi-Z-Source Inverter (QZSI). The application of QZSI using FRG to feed micro grid is proposed for the first time in this research work. The QZSI can realize buck/boost, inversion and power conditioning in a single stage with improved reliability. Also it features a wide range of voltage gain which is suitable for applications in wind systems, due to the fact that the wind generator output varies widely with wind velocity. In addition, the modified Space Vector PWM (SVPWM) technique is proposed in this paper to satisfy the shoot-through characteristic of QZSI. This also adds to the contribution of this research work. In this part I of this full research, modelling of the small scale FRG for wind system using Finite Element Analysis (FEA) is presented. The major parameter of FRG viz, voltage, current, torque and power are analyzed, validated and then represented in d-q model. The simulation results are validated with the analytical results. An experimental set-up to run the full procedure reported in this paper. These results form the basis for part II of this research work

On-sky wide field adaptive optics correction using multiple laser guide stars at the MMT

We describe results from the first astronomical adaptive optics system to use multiple laser guide stars, located at the 6.5-m MMT telescope in Arizona. Its initial operational mode, ground-layer adaptive optics (GLAO), provides uniform stellar wavefront correction within the 2 arc minute diameter laser beacon constellation, reducing the stellar image widths by as much as 53%, from 0.70 to 0.33 arc seconds at lambda = 2.14 microns. GLAO is achieved by applying a correction to the telescope's adaptive secondary mirror that is an average of wavefront measurements from five laser beacons supplemented with image motion from a faint stellar source. Optimization of the adaptive optics system in subsequent commissioning runs will further improve correction performance where it is predicted to deliver 0.1 to 0.2 arc second resolution in the near-infrared during a majority of seeing conditions.Comment: 13 pages, 1 table, 7 figures.

Intravitreal triamcinolone and its effect on intraocular pressure

INTRODUCTION: Periocular and Orbital injections of long-acting corticosteroids are being used to treat inflammatory conditions of the eye for many years. However it has been suggested that peribulbar injection may not be adequate to treat chronic ocular disease because their action is partly due to systemic absorption of the drug and their effectiveness lasts only for a few days to weeks. Intraocular administration has the potential to deliver steroids at high local concentrations. AIMS AND OBJECTIVES: To study the effect of intravitreal triamcinolone on intraocular pressure in eyes with no preexisting evidence of glaucoma. INCLUSION CRITERIA: Patients with progressive decrease in visual acuity due to 1. Exudative age related macular degeneration with subfoveal neovascularisation 2. Diffuse diabetic macular edema 3. Macular edema due to central retinal vein occlusion, branch retinal vein occlusion. 4. Cystoid macular edema following cataract surgery. 5. Macular edema following laser treatment. EXCLUSION CRITERIA: Patients with pre existing glaucoma and others like irregular cornea. MATERIALS AND METHODS: It was a prospective consecutive non comparative interventional case series study conducted in Aravind eye hospital and includes all patients with diffuse diabetic macular edema, cystoid macular edema following cataract surgery, macular edema due to central retinal vein occlusion ,branch retinal vein occlusion, macular edema following laser treatment, exudative age related macular degeneration with sub foveal neovascularisation. Treatment was with intravitreal triamcinolone acetonide after obtaining informed consent from all the patients. Intraocular pressure measured before the procedure and after the procedure and at one month, three months and six months by Goldman applanation tonometer. RESULTS: In the study group mean intraocular pressure increased significantly (p=0.000) after the intravitreal triamcinolone injection from 15.03 ± 2.989 mm Hg to 23.65 ± 11.226 mm Hg, during follow up. The mean rise in intraocular pressure was 8.62 ± 10.647 mm Hg, with the proportion increase being 59.03% Rise in intraocular pressure is defined as measurements outside the normal range at least one IOP measurement higher than 21 mm Hg. Increased IOP was observed in 31 patients in this series. Increase in IOP is defined as the difference between maximal postoperative IOP and baseline IOP. Mean increase in IOP for the entire study group was 8.62 ± 10.647 mm Hg. DISCUSSION: The aim of this study was to analyze the effects of intravitreal triamcinolone on IOP and to find out the baseline characteristics that can cause increase in IOP. Variables that were analyzed in this study included age gender systemic disease, ocular condition for which the drug was administered, baseline IOP. Age proved to be an important determinant in the development of increased intraocular pressure (p=0.005) increased IOP tend to occur in younger age group than the older age group and persists for a longer time. At the end of one month follow up 40% of the patients aged less than or equal to 45 years showed an increase in IOP. At the end of 3 months 50% had increase in IOP, and at 6 months 30% had increase in IOP. The mean age of triamcinolone responders in other studies were relatively high compared to this study group. Though Jonas et al., found a tendency of increased IOP in younger age group their mean age of triamcinolone responders was 71.3 ± 9.9 years which was very high compared to this study. Smithen et al., did not find any correlation with age. LIMITATIONS OF THE STUDY: 1. Small sample size. Though there was significant variation with age and occurrence of increased IOP, since the no. of patients were very less the results could not be generalized and further studies are required to determine the age limit for intravitreal triamcinolone acetonide. 2. Baseline IOP Since baseline IOP was determined on a single measurement taken by different persons at different time of time of the day which might not reflect the true baseline IOP. 3. Follow up period Follow up period was 6 months while intravitreal triamcinolone might persist in the eye for more than 9 months. CONCLUSION: A prospective study on 94 eyes after the administration of a single dose of intravitreal triamcinolone acetonide showed that 1. Incidence of IOP elevation was 33% 2. Mean time of increase of IOP was 2.9 months. 3. Incidence of ocular hypertension in 1st month was 24% 4. Age and baseline IOP could be the positive predictive factors. 5. 90% of the cases were controlled with medical therapy. IOP elevation was transient and 90% of cases did not have optic nerve head changes and elevated IOP was controlled with medications

Performance analysis on direct torque controlled induction motor drive with varying hysteresis controller bandwidth

The fore most issue in DTC based induction motor drive is its torque ripples. The core objective of this paper is to reduce the electromagnetic torque ripples by varying the hysteresis controller bandwidth. Space Vector Modulation (SVM) based Direct Torque Controlled (DTC) induction motor drive is simulated in MATLAB/SIMULINK environment and its performance is studied with step change in load torque. The influence of hysteresis controller bandwidth on the performance of induction motor drive is analysed in terms of stator flux and electromagnetic torque ripples. The electromagnetic torque response and the stator flux trajectory for different values of hysteresis controller bandwidth are obtained and the results are presented

Moving Beyond Youth Prisons: Lessons from New York City’s Implementation of Close to Home

In the mid-1990s, New York’s youth prison system reflected the dominant paradigm across the country – a heavy reliance on incarceration for young people caught up in the juvenile justice system. During this time, roughly 3,800 youth convicted of crimes annually were sent to large facilities, operated either by the New York State Office of Children and Family Services (OCFS) or by private providers contracted by OCFS. These facilities were largely located in upstate New York, far from youths’ homes and communities, particularly for youth from New York City (Sickmund et al. 2017; New York State (NYS) Office of the State Comptroller 2001). Upon returning home from these placements, youth often felt disconnected, resulting in poor outcomes. A 2009 study indicated that by age 28, 71 percent of boys released from New York State’s juvenile placement system spent some time in an adult jail or prison (Coleman, Do Han Kim & Therese 2009). Fast forward twenty years, and things in New York looked dramatically different. By 2016, New York City no longer sent any youth from its Family Court to state-operated youth prisons. Today, only around 100 New York City youth are placed from Family Court into any kind of residential facility, about a dozen of whom are in a locked facility. Not only are there dramatically fewer youth in residential placements, but those who do get placed now go to smaller, more home-like settings that attend to public safety without mirroring the punitive, correctional approaches embodied by previous youth prisons. This case study outlines what happened in the intervening years to achieve these remarkable results. By sharing New York City’s story, we offer a roadmap for other jurisdictions looking to realign their juvenile justice systems, adapting the lessons learned about what worked and what did not to meet their specific circumstances

Prognóstico de exploração no Chat GPT com ética de inteligência artificial

Natural language processing innovations in the past few decades have made it feasible to synthesis and comprehend coherent text in a variety of ways, turning theoretical techniques into practical implementations. Both report summarizing software and sectors like content writers have been significantly impacted by the extensive Language-model. A huge language model, however, could show evidence of social prejudice, giving moral as well as environmental hazards from negligence, according to observations. Therefore, it is necessary to develop comprehensive guidelines for responsible LLM (Large Language Models). Despite the fact that numerous empirical investigations show that sophisticated large language models has very few ethical difficulties, there isn't a thorough investigation and consumers study of the legality of present large language model use. We use a qualitative study method on OpenAI's ChatGPT3 to solution-focus the real-world ethical risks in current large language models in order to further guide ongoing efforts on responsibly constructing ethical large language models. We carefully review ChatGPT3 from the four perspectives of bias and robustness. According to our stated opinions, we objectively benchmark ChatGPT3 on a number of sample datasets. In this work, it was found that a substantial fraction of principled problems are not solved by the current benchmarks; therefore new case examples were provided to support this. Additionally discussed were the importance of the findings regarding ChatGPT3's AI ethics, potential problems in the future, and helpful design considerations for big language models. This study may provide some guidance for future investigations into and mitigation of the ethical risks offered by technology in large Language Models applications.Las innovaciones en el procesamiento del lenguaje natural en las últimas décadas han hecho posible sintetizar y comprender textos coherentes en una variedad de formas, transformando las técnicas teóricas en implementaciones prácticas.

AN ANALYSIS OF BILATERAL TRADE BETWEEN INDIA AND KOREA

India and Republic of Korea (Korea) have been engaging in the bilateral trade relationship from 1962. Though the trade relationship exists for 56 years between the countries, very limited researches have conducted on the trade relationship between the countries. Hence, the present study made an attempt to fill the gap in the literature by assessing and understanding trade pattern of two countries. Based on the existing studies and the availability of data, qualitative methods have been utilized to analyze composition of trade between India and Korea. Further, the trade intensity index, intra industry trade index, and revealed comparative advantage index have been utilized to assess the dynamics of the bilateral trade between India and Korea. It is observed from the trade intensity index that, India’s trade with Korea is less than it should and thus India has a great scope to expand its trade with Korea. There are 9 commodity groups alone having highest intra industry index value and the remaining smaller values indicates less trade between the countries. Comparative advantage index shows that there were no overlaps in two countries trade; therefore two countries have a chance to increase their trade with each other. Since very limited studies have analyzed bilateral trade between India and Korea, the present work assesses the trade pattern between the countries, and the factors motivating such trade. Moreover, the findings would be helpful to promote the commercial as well as economic relations between the countries

Organosolv process for deconstruction of highly recalcitrant cotton stalks

64-71Burning crop residues in a cotton fields adds to environmental pollution and it demands a sustainable solution. As an alternative to burning, cotton biomass can be fractionated into sugars which would not only mitigate the pollution concern but also bring value addition. Here, we propose a process for deconstruction of the highly recalcitrant cotton stalk using a combination of organic and mineral acid fractionation. It includes treatment with formic acid (67 wt. %) at a solid to liquid ratio of 1:4 for 30 min at 130°C. Subsequent treatment with 2% (w/w) nitric acid and de-esterification with 0.5 % (w/v) sodium carbonate resulted in delignification of about 89.01%. The enzymatic hydrolysis using 25 FPU of Cellic Ctec3 at a biomass load of 5% (w/v) gave a glucan yield of 68% in 48 h. This is one of the few studies on deconstruction of a highly recalcitrant biomass with high lignin content

TRIBAL PLANTS AND THEIR INBORN ANTIMICROBIAL ACTIVITIES

The importance of medicinal plants in traditional health-care practices provides clues to new areas of research and in the biodiversity of conservation. Right from the beginning, the documentation of traditional knowledge, especially on the medicinal uses of plants, has provided many important drugs for the modern day. Even today, this area holds much more hidden treasure as almost 80% of the human population in developing countries depend on plant resources for health care. Keeping this in view, the present study was initiated to document the traditionally used tribal plants and their inborn antimicrobial activity which is enhanced on the synthesis of noble metal nanoparticles
