In this paper, we explore the possibility of mapping devices designed in TCAD environment to its modeled version developed in cadence virtuoso environment using a look-up table （LUT） approach. Circuit simu- lation of newly designed devices in TCAD environment is a very slow and tedious process involving complex scripting. Hence, the LUT based modeling approach has been proposed as a faster and easier alternative in ca- dence environment. The LUTs are prepared by extracting data from the device characteristics obtained from device simulation in TCAD. A comparative study is shown between the TCAD simulation and the LUT-based alternative to showcase the accuracy of modeled devices. Finally the look-up table approach is used to evaluate the perform- ance of circuits implemented using 14 nm nMOSFET.

作者： Pritha kundu Independent researcher West Bengal India

Since the 1980s and 1980s, a new trend in the discipline of Translation Studies has emerged beyond the boundaries of Europe. Scholars from post-colonial nations like Canada, India, China, Africa, and Latin America have argued that translation was used in the past as a means of depriving the colonised people of their voice. In the colonial structure, the hegemonic culture used to dominate, making the others subservient. Translation in the colonial period reflected that hierarchy. In this light, decades after the independence of India, translation from a reverse direction, that is, rendering popular English texts in minority languages, may be seen as a process of＂writing back＂. Even if the original text concerned is not a ＂political＂ writing, and the translation is apparently meant for ＂safer-zones＂ such as ＂young students＇ literature＂, a tendency of claiming cultural equality, overlapping the translator＇s own cultural and literary heritage with the original author＇s, can be discovered. This paper attempts to focus on these issues in a particular text—the 1995 Bengali translation of Marie Corelli＇s 1921 science-fiction, The Secret Power. The purpose of this paper is to explore how Sudhindranath Raha has intermingled Biblical references and Western contexts with allusions to Indian culture and Sanskrit literature, thereby claiming a space for mutual understanding and respect between two cultures.

Biodiesel is an alternative renewable fuel which is produced by using biomass resources. Its physicochemical properties are close to those of the petroleum diesel fuel. This study highlights biodiesel production from safflower seed oil. The main aim of this experimental work is to optimize the process parameters, namely the methanolto-oil molar ratio, catalyst concentration, reaction time and reaction temperature for biodiesel production. The Taguchi robust design approach was used with an L9 orthogonal array to analyze the influence of process factors on performance parameters. The results showed that the optimum yield of biodiesel was 93.8% with viscosity 5.60 c St, with a methanol-to-oil molar ratio of 4:1, catalyst concentration of 1.5 wt%, reaction time of 90 min and reaction temperature of 60 ℃. The catalyst concentration was found to be the most influencing parameter which contributed 51.1% and 50.8% of the total effect on the yield of biodiesel, Y;, and viscosity of biodiesel, Y;, respectively.

AIM: To determine the causative agents of fungal keratitis and study the predisposing factors over a period of ten years in a single tertiary care hospital. ·METHODS: A retrospective analysis of fungal corneal ulcers was done from 2003-2012. Patients’ clinical data were noted from the file records. Correlation of histopathological diagnosis was done with the report on fungal culture. · RESULTS: Mycotic keratitis was established in 44 cases by a positive fungal culture. Direct microscopic examination of potassium hydroxide(KOH) mounts revealed fungal elements in 39 cases while 40 cases showed fungus on Gram stained smears. Males(54.55%) were more commonly affected than the females(45.45%). The age ranged from 18 to 82 years. Most common age group to be involved was 41-60 years. Predisposing risk factors were seen in 34(77.27%) cases. Most common findings on clinical examination were anterior chamber reaction and conjunctival injection seen in all the cases. Other common findings were stromal infiltration and hypopyon seen in 20(45.45%) and 18(40.91%) cases respectively. On histopathological examination the fungus was typed,as aspergillus in 34 cases while no definite typing was possible in 10 cases. The predominant isolate was aspergillus flavus(59.09%) followed by fusarium(15.91%). Mixed fungal and bacterial infection was seen in 3(6.82%) cases. ·CONCLUSION: Although culture is the gold standard for definitive diagnosis of fungal keratitis,direct microscopic examination of corneal scrapings or histomorphological evaluation of biopsies allow a rapidpreliminary diagnosis. Early administration of antifungal treatment helps in preventing dreadful complications.
