Antimicrobial Efficacy of Various Concentrations of Bamboo Salt against Enterococcus faecalis and Candida albicans: An in vitro Study
No full textABSTRACT
Sodium hypochlorite (NaOCl) remains the gold standard against which any new endodontic irrigant is compared. But, its inadvertent extrusion beyond the confines of the root canal can be caustic to vital periapical or periodontal tissues. There has been an increase in the use of herbal medicines as irrigants over the last two decades. Bamboo salt is a Korean folk medicine, which shows promising antimicrobial, antioxidant, and anti-inflammatory properties. The aim of this in vitro study was to comparatively evaluate the effectiveness of 1, 3, and 5% bamboo salt against Enterococcus faecalis and Candida albicans using agar diffusion test; 4% NaOCl was used as control. The experiment was performed in triplicate and the zone of inhibition (ZOI) was measured. The results of the present study showed that 4% NaOCl and 5% bamboo salt showed significantly higher mean ZOI than the other groups against E. faecalis; 4% NaOCl showed significantly higher mean ZOI than the other groups against C. albicans, followed by 5 and 3% bamboo salt. Hence, it can be concluded that 4% NaOCl proved to be the most effective antimicrobial against both the species; 5% bamboo salt was as effective as 4% NaOCl against E. faecalis, but significantly less effective against C. albicans.

STUDY OF IMAGE DE-NOISING USING PCA LOCAL PIXEL GROUPING
No full textIn this paper Local Pixel Grouping (LPG) is used to de-noise the noisy images which help in preserving the image local structures. The image obtained by using LPG is further filtered by using Principal Component Analysis (PCA). The corresponding de-noised image is compared with the original image by using measures like mean square error (MSE), root mean square error (RMSE), peak signal to noise ratio (PSNR), structural similarity index (SSIM), mean absolute error (MAE), and structural content (STC). From the performance measure it is seen that LPG-PCA performs better de-noising than the other existing de-noising method.

Thank you.Non-Alcoholic Fatty Liver Disease (NAFLD) is an increasingly common affliction linked to the incidence of diabetes and obesity. The hallmark symptom of NAFLD is liver fibrosis, a change in tissue tiber structure in response to disease. NAFLD is currently defined as a histopathologic condition requiring biopsy to diagnose. However, the significant morbidity and high sampling variability associated with biopsy make it less than ideal for clinical use. Several non-invasive, imaging based methods have been proposed to track progression of liver fibrosis and NAFLD. Quantitative MRI techniques using T2 and Apparent Diffusion Coefficient (ADC) are particularly promising. The spleen is typically used as a reference organ for liver studies due to its proximity in vivo to the liver. The objective of this study is to show that the MR parameters of the spleen do not change in response to liver disease, and that the spleen is an appropriate reference organ for imaging of the liver. Volume, T2, and ADC data were reference organ for imaging of the liver. Volume, T2, and ADC data were acquired from spleens of mice at progressively more serious stages of NAFLD. Volumes of spleens showed an increase from early to late stage NAFLD. T2 and ADC remained the same throughout the course of disease. The results of this study indicate spleens experience no consistent change in liver disease sensitive MR parameters, and therefore are an appropriate reference organ for NAFLD diagnosis via MR imaging
Lohkoketjupohjaiset terveydenhuollon datan yhteensopivuus- ja yksityisyydensuojajärjestelmät
No full textElectronic Health/Medical Records (EHR/EMR) lay the foundation for securely maintaining medical records. The traditional EHR systems are not effectively managed data manipulation, delayed communication, trustless data storage, data cooperation, and distribution.
Blockchain technology can play a major role in healthcare cases. This is because it uses decentralized distributed ledgers to securely manage all parties within the network. It also handles individual data through smart contracts, which can be pre-programmed by the patient for access and maintenance of healthcare data.
This thesis focuses on exploring the blockchain in digital healthcare services such as Electronic Health/Medical Records (EHR/EMR). Blockchain-based implementations of Ethereum allow patients to store their medical data with smart contracts that can perform activities such as Registration, Data Append, and Data Retrieve. The challenges faced during the implementation of blockchain protocols are discussed and analyzed in the scope of finding sustainable solutions to develop secure and reliable operation

Epic legacies: Hindu cultural nationalism and female sexual identities in India 1920-1960
No full textPhDThe thesis investigates the cultural interventions of Hindu nationalist, C. Rajagopalachari (CR), by
offering a close reading of his re-tellings of the Hindu epics, The Mahabharata (1951) and The
Ramayana (1956). It positions them alongside the writings of M. K. Gandhi and the key responses to
Katherine Mayo’s controversial text Mother India (1927). The thesis explores the central female
protagonists of the epics – Sita and Draupadi – asking how these poetic representations illuminate the
ways in which femininity was imagined by an influential Hindu ideologue during the early years of
Indian Independence.
Using close textual analysis as my principal method I suggest that these popular-literary
representations of sexual identities in Hindu culture functioned as one means by which Hindu
nationalists ultimately sought to regulate gender roles and modes of being. I focus on texts emerging
in the years immediately before and after Independence and Partition. In this period, I suggest, the
heroines of these versions of the epic texts are divested of their bodies and of their mythic powers in
order to create pliant, de-sexualised female icons for women in the new nation to emulate.
Through an examination of the responses to Katherine Mayo’s Mother India (1927), and of Gandhi’s
writings, I argue that there one can discern an attempt in the Hindu Indian script to define female
sexual identity as maternal, predominantly in service to the nation.
These themes, I argue, were later articulated in CR’s recasting of the Hindu epics. CR’s epics
represent the vision of gender within Hindu nationalism that highlights female chastity in the epics,
elevating female chastity into an authentic and perennial virtue. I argue, however, that these ‘new’
representations in fact mark a re-working of much older traditions that carries forward ideas from the
colonial period into the period of Independence. I explore this longer colonial tradition in the
Prologue, through a textual analysis of the work of William Jones and James Mill.
Thus my focus concerns the symbolic forms of the nation – its mythologies and icons – as brought to
life by an emergent Hindu nationalism, suggesting that these symbolic forms offer an insight into the
gendering of the independent nation. The epics represented an idealised model of Hindu femininity. I
recognise, of course, that these identities are always contested, always unfinished. However I suggest
that, through the recasting of the epic heroines, an idea of female sexuality entered into what senior
Hindu nationalist and Congressman, K.M. Munshi, called ‘the unconscious of India’
Comparison of Artificial Intelligence Based Maximum Power Point Techniques for Photovoltaic systems
No full textMaximum Power Point Tracking technologies are being used in traditional PV system charge controllers to enhance the power conversion efficiency. An MPPT controller will ensure power extracted from the PV panels during varying climatic conditions is always maximum. This will ensure that maximum power is flowing between the panel and load. As both Temperature and Irradiation levels vary during the day, maximum power point trackers are an inevitable component in a PV system. As solar energy holds a major share in renewable energy in the world market, an improvement in MPPT technique makes the efficiency of the PV system increase and in turn cost reduction possible. However, the efficiency of conventional MPPT Techniques suffers from failing in tracking MPPT at fast varying climatic conditions and falling in local maxima of maximum power point than global maxima. The issues of stability, tracking speed, and accuracy can be solved using intelligent MPPT techniques methods based on soft computing tools: Therefore, this paper aims to study and provide a comparative analysis of two AI-based MPPT techniques such as ANN and ANFIS. The MPPT techniques considered in this study are ANN and ANFIS. Performance evaluation is carried out using MATLAB Simulation. Experimental results indicate that the two methods ANN and ANFIS are more efficient than conventional MPPT techniques due to its capability to avoid local MPP and partially shaded conditions.Maximum Power Point Tracking technologies are being used in traditional PV system charge controllers to enhance the power conversion efficiency. An MPPT controller will ensure power extracted from the PV panels during varying climatic conditions is always maximum. This will ensure that maximum power is flowing between the panel and load. As both Temperature and Irradiation levels vary during the day, maximum power point trackers are an inevitable component in a PV system. The renewable energy source has a vital role in supplying sustainable power to meet the rising electricity demands. However, the PV system performance heavily depends on environmental conditions. This, in turn, causes efficiency to be less and in turn higher cost. For maximum power to be transferred from the PV panels under varying climatic conditions PV systems should operate at Maximum Power Point

Sakai (1961: 137) commented that the “ <i>P. alcocki</i> Doflein (nec Wood-Mason) may be a different species; the carapace of Doflein’s species seems to be circular in outline just as in the new species [<i>P. major</i>], but the merus and carpus of the pereiopods are spinulated along the posterior border.” Tirmizi & Serène (1971: 31) agreed but deferred acting on it; neither did Prema et al. (2018). It is clear from the figure in Doflein (1904: pl. 14 figs. 8, 9) that the carapace shape is quite different from that of <i>P. alcocki</i> s. str., being globose rather than transversely subovate. Doflein’s (1904) figures also show the carapace margins as lined with fine granules and the surfaces of the ambulatory meri covered with spinules; characters associated with <i>P. pattersoni</i>, new species, as defined here.

Ennvagai Thaervu, manikkadai nool, jothidam and panchapatchi sasthiram were focused in the study.
In this study, following data were observed and discussed for the 80 cases.
Among 80 cases, 100% had Abdominal pain, 70% had early satiety, 83.75% had Vomiting, 28.75% had burning sensation, 73.75% had kabhapitha Naadi, 52.5% had Maapadithal in Naa. 66.25% had muthu in neikkuri. 37,5% had 8 fbs and 31% had 9 ½ in manikadai nool. 58.75% had Elansivappu in Vizhi, 67.5% had Normal in malam. 70% had ila manjal niram, 62% had nurai absent and 94% had enjal absent in urine. 52% had Vaadhapitha dhegi and 32% had Pithavaadha dhegi.
CONCLUSION:
The disease Kaba Gunmam was taken for clinical study from Yugi vaithiya chinthamani - 800. The study on kaba gunmam were carried out in this dissertation and observe the changes in udal thadhukkal and uyir thadhukkal. the changes in the udal thadhukkal and uyir thadhukkal were assessed by Siddha parameters such as ennvagai thervugal and Manikkadai nool.
From this study Kaba Gunmam (Gastric ulcer) cases were examined through siddha diagnostic parameters Enn vagai thervu, manikadai nool, jothidam and panchapatchi sasthiram and also with the help of modern diagnosis through Lab investigations and special investigations like endoscopy. Above methods are used to collect data and from the data collection the author concluded that through the siddha diagnostic parameters, naadi, neiikuri, manikadai nool and panjapatchi saasthiram are mainly used for the conformation of Kaba gunmam (Gastric ulcer). The results obtained from this study may be correlated with the gastric ulcer. In would be helpful in future studies with more number of cases, diagnosing a case is much more important to choose the way of treatment
