Classification of Cervical Cancer Using Artificial Neural Networks
No full textAbstractArtificial neural network (ANN) plays an important role in many medical imaging applications. The detection of cervical cancer cells uses an ANN for classifying the normal and abnormal cells in the cervix region of the uterus. Cervical cancer detection is very challenging because this cancer occurs without any symptoms. The classification between the normal, abnormal and cancerous cells is identified by using an artificial neural network which produces accurate results than the manual screening methods like Pap smear and Liquid cytology based (LCB) test. The ANN uses several architectures for easy and accurate detection of cervical cells. In this paper, a survey and analysis on the different types of architecture in the ANN with its accuracy results and performance are discussed. A brief description about the working and detection of cervical cancer is presented which is useful for the classification of normal and abnormal cervical cells

No full textPrince Sultan University through research group Nonlinear Analysis Methods in Applied Mathematics (NAMAM) [RG-DES-2017-0]; DST-FIST Scheme, New Delhi, IndiaDepartment of Science & Technology (India) [SR/FST/MSI-115/2016]J. Alzabut would like to thank Prince Sultan University for supporting this work through research group Nonlinear Analysis Methods in Applied Mathematics (NAMAM) group number RG-DES-2017-0.; The fourth author was supported by DST-FIST Scheme (Grant No: SR/FST/MSI-115/2016), New Delhi, India.In this paper, we study the nonoscillatory behavior of three classes of fractional difference equations. The investigations are presented in three different folds. Unlike most existing nonoscillation results which have been established by employing Riccati transformation technique, we employ herein an easily verifiable approach based on the fractional Taylor's difference formula, some features of discrete fractional calculus and mathematical inequalities. The theoretical findings are demonstrated by examples. We end the paper by a concluding remark

Improving the Cardamom Marketing: Assessing the Marketing Efficiency of Cardamom in Theni District, Tamil Nadu
No full textIntroduction: The cardamom is the oldest spices and belongs to Zingiberaceae family. It is cultivated in the thick shady, rainy forests of the Western Ghats of the South India. The major growing states are Kerala, Karnataka and Tamil Nadu in reference to green cardamom (Small) and its botanical name Elettaria cardamomum. The part of Theni district is constituted by thick vegetations of hills of Western Ghats and Cumbum Valley at Bodi and Uthamapalayam taluk. In these areas, the farmers are cultivating the Cardamom. This study aims to find out the socio-economic characters, marketing behavior, assess the marketing efficiency of different supply channels and ranking the major problems faced by farmers to market their agricultural product.
Methodology: The author used both primary and secondary data. The maximum area covered by cardamom was used as criteria for selecting the blocks. Purposive random sampling method was used to select the villages and the data was collected from the 60 farmers and other stakeholders using well-structured questionnaire. The descriptive statistics and percentage analysis were used for interpreting the results. For marketing analysis, marketing costs, marketing margin and price spread were estimated. For marketing efficiency, Acharya’s method (2003) was used.
Results: The 34 respondents with 56.67 percent were found to be 21-35 years of age group. It was found that 7 respondents only with 11.67 percent and 26 respondents with 43.33 percent were found to be illiterate and the annual turnover of 1-5 lakh respectively. Using Acharya’s method (2003), the marketing efficiency of the channel I, II, III were 5.92, 9.97, 7.27 respectively. The price spread in the marketing channel I, II, and III are Rs. 295.94 per Kg, Rs. 163.54 per Kg and 229.48 per Kg respectively. It was shown that channel II is efficient due to high efficiency value and less price spread. Producer in the marketing channel II had highest share (90.88) in consumer rupee. The result showed that the Lack of timely adequate funds were major problem faced by the cardamom farmers with garret mean score of 65.23. The financial problems were common in the respondents.
Conclusion: Marketing channel II was efficient because the spice auction center plays a vital role in protecting the farmer as well as consumer from the malpractices and exploitation of Intermediaries and to provide the transparency in trading operations of cardamom. The government may increase the financial assistance or technical support program to support the cardamom growers of the Tamil Nadu. The board should educate the farmers to grade or sort the cardamom before entering the e-Auction center to get better price for better quality of the commodity and to expand the pilot project of separate e-auctions for lab tested cardamom for artificial colours and pesticidal residues to potential markets of Tamil Nadu

Use of failure-to-rescue to identify international variation in postoperative care in low-, middle- and high-income countries: a 7-day cohort study of elective surgery.
No full textBackground: The incidence and impact of postoperative complications are poorly described. Failure-to-rescue, the rate of death following complications, is an important quality measure for perioperative care but has not been investigated across multiple health care systems. Methods: We analysed data collected during the International Surgical Outcomes Study, an international 7-day cohort study of adults undergoing elective inpatient surgery. Hospitals were ranked by quintiles according to surgical procedural volume (Q1 lowest to Q5 highest). For each quintile we assessed in-hospital complications rates, mortality, and failure-to-rescue. We repeated this analysis ranking hospitals by risk-adjusted complication rates (Q1 lowest to Q5 highest). Results: A total of 44 814 patients from 474 hospitals in 27 low-, middle-, and high-income countries were available for analysis. Of these, 7508 (17%) developed one or more postoperative complication, with 207 deaths in hospital (0.5%), giving an overall failure-to-rescue rate of 2.8%. When hospitals were ranked in quintiles by procedural volume, we identified a three-fold variation in mortality (Q1: 0.6% vs Q5: 0.2%) and a two-fold variation in failure-to-rescue (Q1: 3.6% vs Q5: 1.7%). Ranking hospitals in quintiles by risk-adjusted complication rate further confirmed the presence of important variations in failure-to-rescue, indicating differences between hospitals in the risk of death among patients after they develop complications. Conclusions: Comparison of failure-to-rescue rates across health care systems suggests the presence of preventable postoperative deaths. Using such metrics, developing nations could benefit from a data-driven approach to quality improvement, which has proved effective in high-income countries
