Mohanlal Sukhadia University also called University of Udaipur is a public university situated in Udaipur city in Indian state of Rajasthan. The university consists of four constituent colleges and 60 affiliated colleges from the districts of Udaipur, Chittorgarh, Rajsamand, Banswara, Dungarpur and Sirohi. The earlier agricultural University was turned into a multi-faculty university in 1964 and named as University of Udaipur. In 1984 it was renamed as Mohanlal Sukhadia University in memory of politician Mohanlal Sukhadia. Wikipedia.

Even though patients often arrive early and out of turn for scheduled appointments in outpatient clinics, no research has been undertaken to establish whether an available provider should see an early patient right away (preempt) or wait for the patient scheduled next. This problem, which we call the "Wait-Preempt Dilemma," is particularly relevant for "high-service-level" clinics (such as psychotherapy, chiropractic, acupuncture), where preempting may cause the missing patient to wait for an excessively long time, should she show up soon. Typically, the dilemma is resolved by preemption, where the provider starts serving the patient who has already arrived to avoid staying idle. By contrast, we analytically determine the time intervals where it is optimal to preempt and those where it is optimal to wait, and find that in some cases the provider should in fact stay idle, even in the presence of waiting patients. Our results suggest that the proposed analytical method outperforms the always-preempt policy in clinics that do not overbook and have service times longer than 30 minutes. In these cases, the analytical method dramatically reduces patient waiting times at the cost of a modest increase in overtime. By contrast, in clinics that overbook or have short service times, the two policies perform similarly, and hence the always-preempt policy is preferable due to its simplicity. A software application is provided that clinics can readily use to solve the wait-preempt dilemma. © 2015 Production and Operations Management Society. Source

During the present study effect of different factors were studied during in vitro growth and multiplication of adventitious shoot buds induced from de-embryonated cotyledon explants of groundnut cultivar ‘JL-24’. Optimum shoot multiplication rate of 7.0 folds and average shoot length of 3.0 cm was achieved on Murashige and Skoog’s (MS) medium supplemented with 2.0 mgl−1 6-benzylamino purine. During subsequent subculture after every 21 days, an initial shoot number of 3 shoots per explant produced a maximum of 21 shoots per explant after 9 weeks. Sucrose at 3.0 % concentration supported the optimum shoot multiplication rate of 7.0 folds. Lowering or increasing sucrose concentration from the control (3.0 %) proved detrimental for in vitro shoot multiplication and growth. In case of liquid MS medium (without agar) supplemented with 6-benzylamino purine (2.0 mgl−1) and sucrose (3.0 %) the multiplication rate was reduced by 1.5 folds (after 6 weeks) as compared to the semi-solid medium (with 0.8 % agar). Hyperhydricity was also observed in liquid medium. Shoots measuring 3.0–4.0 cm obtained from multiplying cultures were found suitable for rooting. Cent per cent rooting was achieved on 1/4th MS medium with sucrose (2.0 %), agar (0.8 %) and indoleacetic acid (0.5 mgl−1). Subsequent hardening and acclimatization led to 95 % survival of in vitro raised plants. © 2014, The National Academy of Sciences, India. Source

The present communication reports the preparation and physical characterization of CdTe thin films for photovoltaic application. The thin films of thickness 660 nm and 825 nm were deposited on glass and ITO coated glass substrates employing thermal vacuum evaporation deposition method. These as-deposited films were characterized using XRD, UV-Vis spectrophotometer, source meter, SEM and AFM for physical properties. The XRD patterns reveal that the films are crystallized zinc-blende structure of cubic phase with preferred orientation (111) as well as polycrystalline in nature. The optical and crystallographic parameters are calculated and widely discussed. The optical band gap is found in the range 1.52 - 1.94 eV and observed to decrease with thickness. The current-voltage characteristics show that the current is found to be decreased with thickness and the resistivity is increased. The SEM studies show that the films are homogeneous, uniform and free from crystal defects. The grains in the thin films are similar in size and densely packed. The AFM studies reveal that the surface roughness is observed to increase for higher thickness. The experimental results reveal that the films of thickness 825 nm may be used as absorber layer in CdTe/CdS thin film solar cells due to its optical band gap 1.52 eV which is almost identical with the optimum band gap of CdTe and good crystallinity. © 2015 VBRI Press.

This paper presents the influence of thickness on physical properties of polycrystalline CdTe thin films. The thin films of thickness 450 nm, 650 nm and 850 nm were deposited employing thermal vacuum evaporation technique on glass and indium tin oxide (ITO) coated glass substrates. The physical properties of these as-grown thin films were investigated employing the X-ray diffraction (XRD), source meter, UV-Vis spectrophotometer, scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS). The structural analysis reveals that the films have zinc-blende cubic structure and polycrystalline in nature with preferred orientation (111). The structural parameters like lattice constant, interplanar spacing, grain size, strain, dislocation density and number of crystallites per unit area are calculated. The average grain size and optical band gap are found in the range 15.16-21.22 nm and 1.44-1.63 eV respectively and observed to decrease with thickness. The current-voltage characteristics show that the electrical conductivity is observed to decrease with thickness. The surface morphology shows that films are free from crystal defects like pin holes and voids as well as homogeneous and uniform. The EDS patterns show the presence of cadmium and tellurium elements in the as grown films. The experimental results reveal that the film thickness plays significant role on the physical properties of as-grown CdTe thin films and higher thickness may be used as absorber layer to solar cells applications. © 2015 Elsevier B.V.

Abstract This paper presents the physical properties of vacuum evaporated CdTe thin films with post-deposition thermal annealing. The thin films of thickness 500 nm were grown on glass and indium tin oxide (ITO) coated glass substrates employing thermal vacuum evaporation technique followed by post-deposition thermal annealing at temperature 450°C. These films were subjected to the X-ray diffraction (XRD),UV-Vis spectrophotometer, source meter and atomic force microscopy (AFM) for structural, optical, electrical and surface morphological analysis respectively. The X-ray diffraction patterns reveal that the films have zinc-blende structure of single cubic phase with preferred orientation (111) and polycrystalline in nature. The crystallographic and optical parameters are calculated and discussed in brief. The optical band gap is found to be 1.62 eV and 1.52 eV for as-grown and annealed films respectively. The I-V characteristics show that the conductivity is decreased for annealed thin films. The AFM studies reveal that the surface roughness is observed to be increased for thermally annealed films. © 2015 Elsevier B.V. Source
