In this work, we identify the most effective financing methods in the higher education department of Qom University.

For this purpose, comparative studies were conducted on the financing patterns of the world's top universities to identify and benefit from their experiences. Then, using library studies and related research, the background studies was reviewed. After that, during an interview with experts and officials of Qom University, financial options were examined. Apperantly, by sifting financing options using the Binem test, Shannon entropy technique, and finally prioritizing financing options using the Kodas method; An appropriate proposal was presented to improve the financing method of Qom University. 

  Based on these studies, it was observed that the main methods used by the world's top universities to finance themselves come from four main sources: government grants, student payments, investment income and the provision and sale of services and products, and grants and endowments.

Accordingly, the priorities of the proposed financial options in the field of education are to increase the attraction of non-Iranian tuition-paying students; In the field of research, attracting industry and community research projects by faculty members; In the field of facilities and physical spaces, the university uses the capacities of the meeting halls and amphitheaters of the university; In the field of donations and endowments, expansion and diversification of university endowment assets; And in the area of ​​budgeting and planning, the maximum use of legal capacity was set out in the budget notes.

Anti-reflective optical elements prepared on ZnSe substrates are the main optical devices in CO2 lasers. These ‎anti-reflective coatings are used in the far-infrared region at the specified wavelength of 10600 nm. For the preparation phase of these anti-reflective coatings, first, the characterization of the used materials in this wavelength was investigated and then YbF3 and ZnS were chosen. However, a lot of research work has been done in the country to make reflection mirrors of gold and silver for a wavelength of 1.6 microns, but no research has been done on anti-reflective optical window or part of it at this wavelength. Then, anti-reflective coating at 10600 nm was designed by the Macleod software using these two materials. These thin films were deposited on one side of ZnSe substrates by physical vapor deposition (PVD) method with Balzers- Ba510 coating system. Optical element operation was investigated by a 10 W CO2 laser and the transmission was measured for the standard anti-reflection, the polished substrate, and the deposited antireflective element. The results show that the prepared anti-reflective element has 77.84% transmission coefficient. By studying the morphology and thickness of the layers by SEM, it was found that the transmission coefficient of ZnSe substrate is optimized by the prepared anti-reflection element.

TiO2-SnO2 thin films were coated on glass and Al / glass substrates by electron gun method. In coating process، the vacuum was 1. 5×10-5 torr. Then، films were annealed at 450، 500 and 550 ˚ C. The crystallographic structure and film morphology were investigated by means of XRD and SEM. The electrical (I-V) and optical properties were studied by the two point props system and UV/Vis/NIR spectrophotometer. The results showed the films under 550 ˚ C were crystalline. The thickness and grain size were 350 and 50 nm respectively. The electrical conductivity in the sample with Al / glass substrate under 550 ˚ C was better than the other samples. When temperature increased، the energy gap decreased from 4. 05 to 4. 03 eV for direct cases.

Schizophrenia is a compli-cated، debilitative mental disorder. Evide-nce is emerging for the association of pol-ymorphisms in PRODH gene and the increased risk of schizophrenia. In the pres-ent research we investigated the relation-nship between this gene and schizophrenia disease by means of a gene polymorphism using PCR-RFLP technique. Blood samples were prepared from 150 persons suffering from acute Schizophrenia and 160 healthy per-sons volunteering for this project. Based on intended SNP، a pair of primers was design-ned by Oligo7 program and the polymerase chain reaction (PCR) was performed on a thermocycler set. Then the PCR product was treated by appropriate restriction enzymes. Finally، the fragments of digested PCR product were electrophoresed on the gel agarose (4%) and migration pattern of resulted components were compared in he-althy and patient subjects، whereby obtain-ing genotypes of different persons in po-lymorphic position.
