Background: Admission and dispatch of patients is considered as part of the patient treatment process. The aim of this study was to investigate the status and income effects of admission and dispatch of patients in need of vascular surgery in hospitals of Iran University of Medical Sciences in 2018-2019. Methods: The present study is a descriptive cross-sectional study in which a checklist was compiled and the required information about admission and dispatch of patients in Iran University of Medical Sciences was extracted from the MCMC (Medical Care Monitoring Center) system. In order to extract the income of services related to vascular surgery service from the average income of each patient file in need of this service, university hospitals were used. The sampling method was census and 14,481 patients admitted and dispatched were examined. The data were analyzed by descriptive statistics using Excel software. Results: The total number of registrations for dispatch of vascular surgery service was 605, 378 of which were successful. Of these, 145 were from hospitals affiliated to private hospitals and other hospitals affiliated to other medical universities, 233 were related to vascular surgery admissions, and 227 patients were related to failure to dispatch and death. The lost income due to dispatching patients is equal to 4,875,100,680 Rials. Also, the hospitals affiliated to the university have gained income equal to 7,833,782,472 Rials by admitting and not dispatching these patients. Conclusion: The findings showed that the lost income due to dispatching patients requiring vascular surgery is 4,875,100,680 Rials. Also, the earned income resulting from the existence of medical facilities in the field of the patients’ admission to the hospitals affiliated to the university is 7,833,782,472 Rials.

One measure of the maturity of a device technology is the ease and reliability of applying contact metallurgy. Compared to metal contact of silicon, the status of GaAs metallization is still at its primitive stage. With the advent of GaAs MESFET and integrated circuits, very stringent requirements were placed on their metal contacts. During the past few years, extensive researches have been conducted in the area of Au-Ge-Ni in order to lower contact resistances and improve uniformity. In this paper, we report the results of TEM study of interfacial reactions between Ni and GaAs as part of the attempt to understand the role of nickel in Au-Ge-Ni contact of GaAs.N-type, Si-doped, (001) oriented GaAs wafers, 15 mil in thickness, were grown by gradient-freeze method. Nickel thin films, 300Å in thickness, were e-gun deposited on GaAs wafers. The samples were then annealed in dry N2 in a 3-zone diffusion furnace at temperatures 200°C - 600°C for 5-180 minutes. Thin foils for TEM examinations were prepared by chemical polishing from the GaA.s side. TEM investigations were performed with JE0L- 100B and JE0L-200CX electron microscopes.
