Gold and silver in dross were determined by energy-dispersive X-ray fluorescence technique. Sample was prepared by pressed pellet method using microcrystalline cellulose powder as binder, and a method of standard additions was used for quantification. L β X-ray of gold (11.4 keV) and K β X-ray of silver (24.9 keV) were used for analysis. The measured concentrations of gold and silver were 132 ± 8 and 1181 ± 84 mg kg À1, respectively. The results were validated by instrumental neutron activation analysis technique. The t-test indicated that there was no significant difference between results obtained by the two techniques. Energy-dispersive X-ray fluorescence is a simple, precise and accurate technique for the determination of gold and silver in dross.

In order to be successful in the market it is not sufficient to attract new customers, hotels/managers must concentrate on retaining existing customers implementing effective policies of customer satisfaction and loyalty. In hotel industry customer satisfaction is largely hooked upon quality of service. A management approach focused on customer satisfaction can improve customer loyalty, thus increasing the positive image of the hotel. Hotels use a variety of techniques to track Guest satisfaction levels. This research tracks down which are the best and the most used techniques adopted by the hotels and explains why GSTS and online feedback serves as the best method out of all the various techniques. It categorically explains various timelines followed transparency level and hierarchy at which such GSTS reports are reviewed. This research also evaluates the use, effect, and convenience of the GSTS on hotels in Pune region. The data is clearly represented in form of pie charts and graphs to understand the findings at a glance.

Aim and Objectives: The present study was undertaken to compare the LMA Classic with LMA Supreme in assessing the ease of insertion, number of attempts, time for insertion, any unwanted responses, stability of device, peak airway pressure, leak volume and leak fraction and postoperative complications. Methods: A total of 274 patients of ASA grade 1 and 2 were included in the study and divided into two groups with 137 patients in each group: the LMA Classic group (group C) and LMA Supreme group (group S). All patients were induced with propofol 2.5 mg/kg and atracurium 0.5 mg/kg after that appropriate sized supraglottic airway device was inserted. The ease of insertion, number of attempts, duration of insertion, stability of device, peak airway pressure, leak volume and leak fraction and postoperative complications were recorded. Results: The insertion of Supreme LMA was very easy in 134 patients and was easy in 3 patients, difficult in 0 patients while the insertion of Classic LMA was very easy in 122 patients, easy in 15 patients and difficult in 0 patients. The first attempt insertion rate was more with Supreme LMA as compared to Classic LMA. The mean duration of insertion was significantly lower with Supreme LMA than with Classic LMA. The mean airway pressure was similar in both groups. Both devices were stable. Leak volume and Leak fraction was significantly higher in Classic LMA than Supreme LMA. Peri-operative complications were not significantly different between Supreme LMA and Classic LMA. Conclusions: The LMA Supreme is superior to the LMA Classic because of its ease of insertion with lesser leak volume and leak fraction and better first attempt insertion rate.
