Differential subordination and superordination of analytic functions defined by the Dziok–Srivastava linear operator

Abstract: Differential subordination and superordination results are obtained for analytic functions in the open unit disk which are associated with the Dziok–Srivastava linear operator. These results are obtained by investigating appropriate classes of admissible functions. Sandwich-type results are also obtained.

Efficacy of photoluminescence and photocatalytic properties of Mn doped ZrO2 nanoparticles by facile precipitation method

Abstract: Pure ZrO2 and Mn (002, 004, 006, 008 M) doped ZrO2 nanoparticles were successfully prepared by chemical precipitation method The structural, optical, morphological and electronic properties were determined using XRD, UV-DRS, PL, FE-SEM, TEM and XPS techniques The XRD pattern of pure and Mn doped ZrO2 shows the formation of t-tetragonal phase and shifting of tetragonal phase to monoclinic phase The energy gap of pure and Mn doped ZrO2 nanoparticles were computed by UV-DRS spectroscopy The energy gap value of pure and Mn doped ZrO2 nanoparticles decreased from 512 to 246 eV with increase of manganese concentration X-ray Photoelectron spectroscopy (XPS) affirmed the presence of Zr4+ and Mn2+ ion in prepared nanoparticles PL spectra of the pure and Mn doped ZrO2 nanoparticles exhibited oxygen vacancies The photocatalytic actvity of Mn (008 M) doped ZrO2 nanoparticles was successfully sought on photo degradation of Methyl violet and Methylene blue under sunlight irradiation

Tomato Leaf Disease Diagnosis and Severity Measurement

Abstract: Indian economy is mostly dependent on agriculture. One of the highly used food crops in India is Tomato. Hence detection and analysis of leaf disease on tomato plants so as to increase the yield is highly essential. It becomes very hard to manually detect and analyze the tomato leaf diseases. Hence, in this paper we have proposed a segmentation-based approach for automatic segmentation of infected regions. The segmented area is further analyzed for disease classification and severity measurement. Leaf disease detection technique proposed here involves various stages including preprocessing, segmentation, feature extraction, training and classification followed by the severity measurement from the disease segmented region. We have analyzed the performance of different features extraction techniques including color, texture and shape features along with various classification techniques. The performance of the proposed system really inspires the farmers to use the automated system for detection and severity measurement of tomato plant disease.

Service quality in the public sector hospitals: a study in India.

Abstract: Most studies on service quality have been conducted in the context of the private sector of the economy. In fact, in the healthcare setting, for a long time, public-sector hospitals were not expected to excel in the provision of service quality. In a country such as India, even now, public-sector hospital staffs enjoy relatively higher salaries, flexible work schedules, and secure employment until retirement. Because patients do not pay for most services, normally they are concerned only about the quality of the core product. The authors indicate that, even in the public sector context, the quality of the physician and that of the clinical support staff significantly impact patient satisfaction. However, the quality of nonclinical support staff is not found to have any significant effect on patient satisfaction.
