This research describes the thermopower and electric conductivity of CdTe films produced using thermal evaporation technology; the energy activation value of this electrical and thermoelectrically properties are estimated. CdTe sheets have an electrical resistance of about (107. cm). Conductivity was studied, and it was found that the electrical conductivity increased with temperature. At low temperatures, there are two values of activation energy $(Ea1=0.337 eV)$ because of this dependence, but at high temperatures, $(Ea2 = 0.702 eV)$ is the only value of activation energy. The Seebeck coefficient (thermopower) was researched to find that it was temperature-dependent, and it was found that, as the temperature increased, the Seebeck coefficient decreased. The experiment results on thermoelectric power were summarized in a two-paragraph statement. The activation energy was measured to be $(ES = 0.561 eV)$, and the CdTe film was shown to be p-type conductive.

Background: In recent years, infrared thermography tools are used for viral disease detection. However, no study has been to evaluate the value of this device. The current study was designed to review the effectiveness of infrared thermography technique for diagnosis of viral diseases in international airports.Materials and methods: This study was conducted as a systematic review. All of the relevant databases, bibliography of related papers, and companies’ websites were searched using appropriate search strategies and keywords.Results: Totally, 121 papers were recovered in total using different databases and search techniques. Considering the research selection criteria, 13 papers were recognized as suitable.Conclusion: The results showed that although infrared thermography is a safe, rapid and cheap technique in screening and diagnosis of different diseases, current studies do not show any acceptable diagnostic value compared to other diagnostic techniques. It is recommended to use the infrared thermography as a complementary technique.

Background: Tetralogy of Fallot (TOF) refers to a condition in which left ventricular volume is normal or slightly less than normal. Given the differences observed in some Asian patients with TOF، the present study was conducted to investigate left heart by determining Z-scores for the mitral valve in Iranian patients with TOF. Methods: Eligible subjects in this prospective descriptive study comprised all patients with TOF presenting to Shahid Modarres Hospital in Tehran from March 2012 to March 2015 and diagnosed as the candidates for surgery. After determining the need for surgery and the therapeutic method required، the mitral valve size and Z-scores were calculated. We analyzed sex، age، body surface area (BSA)، mitral size (in 2-chamber and 4-chamber view)، mitral Z-score، other cardiac anomalies، number of surgery and previous surgery. Results: Of a total of 80 patients included in the study over 3 years، 29 (36. 3%) were male and 51 (63. 8%) were female. The mean age of the patients was 7. 15± 3. 37 years and their mitral size was found to be 10-27 mm (16. 2± 5. 99 mm) using echocardiography. Z-scores of the mitral valve were also obtained as-3. 09± 2. 11، ranging between-7. 1 SD and +1. 3 SD. 58 (72. 5%) patients have only TOF and 22 (27. 5%) with other cardiac anomalies. 45 patients were for first time underwent surgery and 22 patients for second time، 12 patients for three time and 1 for forth. Of a total of 35 patients had previous surgery، the most common were shunt 15 (42. 9%) and then tetralogy of Fallot total correction (TFTC) in 12 (34. 3%). Of a total of 80 patients، 59 (73. 8%) underwent TFTC، 17 (21. 3%) under pulmonary valve replacement and 4 (5%) shunt. Conclusion: Z-scores of the mitral valve were found to be significantly below the normal value، (i. e. 0± 2 SD)، in the study patients، suggesting the risk of hypoplastic left heart syndrome in Iranian patients with TOF، nevertheless، the type of TOF examined in these patients might have been different from those observed in other races and regions.

Application and interpretation of statistical significance of association are the basic and necessary principle in medical research. Traditionally, hypothesis testing and reporting p-values are widely used to quantify the statistical significance of observed results. In the last two decades, the calculation of a p-value in research and especially the use of a threshold to declare the statistical significance of the p-value have been challenged. The limitations of p-value, such as the dependence of its value on the sample size and not reflecting the clinical significance, have been repeatedly mentioned. The statisticians and methodologists recommend do not report p-value alone, and reporting of effect size index with corresponding confidence interval is mandatory. However, many researchers do not pay attention to this and do not even interpret the p-value correctly. The present study intended, to provide an integrated instruction for reporting the statistical and clinical significance in medical sciences with the approach of hypothesis testing (reporting p-value).

Introduction: The expected values of hematologic and serum biochemical parameters in domestic animal species can be affected by breed, age, environment, and nutrition. Established breed-specific reference intervals (RI) are an important tool for monitoring the health of sheep. There is a lack of published data on biochemical RI for Sngsari sheep. Thus, the aims of this study were to establish RI for select of serum biochemical parameters for Sangsari sheep by Reference value Advisor (RVA) method and provide information on the studied parameters for both sex of this breed in order to form a basis for clinical interpretation. Materials and Methods: Sixty healthy Sangsari sheep including 26 ewes and 34 rams (2– 4 years old) were chosen from the breeding station of Sangsari sheep among 150 sheep in Damghan, Semnan, Iran. The type of feeding, all the animals had free access to water and to good-quality alfalfa hay (90. 0 % DM, 15. 8 CP % DM, 50. 4NDF%DM, 31. 6ADF%DM, 5. 8 lignin% DM, and 2. 2 EE % DM). Concentrate (23 % oats, 36 % corn, 38 % barley, and 3%mineral and vitamin supplements) was provided once daily (200 g per animal per day). In the sampling day, breeder signed a subscription form and completed a primary questionnaire consisting of specific questions about past and current health status, sexual status, medications used, and familial and reproductive medical history. Complete physical examinations were performed by the same experienced veterinarian on each sheep. In order to reduce stress, blood samples were taken in the station with minimal changes in the usual schedule of the sheep. Blood samples (taken from the jugular vein) were collected in simple tubes in order to separate the serum (centrifuged at 3000 rpm for 10 min) for biochemical analysis. Samples transported at +4 ° C to the laboratory department of the Faculty of Veterinary Medicine, Semnan, Iran. Biochemical parameters were measured by a autoanalyzer. These parameters included alkaline phosphatase (ALP), gamma glutamyletransferase (GGT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), total protein (TP) and albumin (Alb). For statistical analysis, data were analyzed by Reference value Advisor and outliers were deleted if detected according to Tukey or Dixon. RIs, according to sample size, were determined using a robust method and following Box-Cox transformation of data. The data were normally distributed, and differences between sexes in biochemical parameters were analyzed using independent sample T test. A value of P<0. 05 was considered as significant. Results and Discussion: The RI of biochemical parameters obtained from adult healthy Sangsari sheep includes the following: ALP 49. 24-564. 84 u/l; GGT 24. 14-62. 23 u/l; AST 10. 86-338. 40 u/l; BUN 6. 91-26. 43 mg/dl; TP 5. 19-13. 95 gr/dl and Alb 0. 92-3. 63 gr/dl. Established RI of biochemical parameters for ewes and rams, respectively including: ALP 29. 98-702. 89 u/l; GGT 22. 41-54. 49 u/l; AST 1. 36-279. 89 u/l; BUN 5. 9526. 86 mg/dl; TP 5. 75-12. 83 gr/dl; Alb 0. 84-2. 77 gr/dl and ALP 106. 08-568. 55 u/l; GGT 20. 80-58. 30 u/l; AST 360. 12 u/l; BUN 8. 15-26. 04 mg/dl; TP 4. 66-15. 59 g/dl and Alb 0. 74-3. 77 g/dl. Interpretation of the biochemical results in different breeds of sheep, with regard to RI for each parameter, in conjunction with history, clinical findings and other paraclinical tests helps the clinician to reach a definitive diagnosis. A unique feature of Sangsari sheep is that they are highly adaptable with desert and mountain ranges with high tolerance of drought conditions. This breed is also relatively small size and light weight, and most studies have focused on genetic characteristics associated with this trait. In view of the characteristics mentioned above and considering the lack of reference range for biochemical parameters, it is necessary to determine reference intervals in Sangsari sheep. In order to establish a comprehensive reference interval in Sangsari sheep, a select biochemical parameters were evaluated in the present study. Almost most of the established RI for biochemical parameters in this study differed from previously published RI, so that the lower and upper limits of RI of theses parameters (with the exception of BUN) were lower and higher than the values previously reported. Differences between obtained RI for the Sangsari sheep and previously reported RI for other breeds may be attributed to variations in hormonal influences, hydration status, dietary differences, or adaptations to a desert environment, age, breed, season of study and analytic method. Conclusion: The obtained data provided reference interval for biochemical parameters in Sangsari sheep for the first time. Present study demonstrates significant differences in most of the biochemical parameters. Reference intervals determined in this study provide a baseline for interpreting biochemical results in Sangsari sheep, and contribute to optimization of the management of this species.
