Objective: To confirm the efficacy of non-antibiotic treatment with prostaglandin F2α(PGF2α) in dairy cows affected by severe clinical endometritis in (30±3) days in milk. Methods: Cows with clinical endometritis Ⅲ (n=399) were aligned into three groups randomly. The first group (n=115) received PGF2α, the second group (n=84) received intrauterine infusion (IUI) of oxytetracycline 10% + PGF2α, and the third group (n=200) received IUI. Cows were inseminated following estrus. The pregnancy status, parity, calving and artificial insemination season, ovaries with corpus luteum at the time of treatment, dystocia, body condition score and treatment groups were included in data analysis. Results: Total pregnancy rate was 40.1% after the first insemination and 94.2% after the third insemination. Overall pregnancy rate of treated cows with IUI+PGF2α(84.5%) was significantly lower than the treated cows with PGF2α(98.3%) or IUI (96%) (P<0.05). The first service pregnancy rate of inseminated cows in summer (14.3%) was lower in comparison with cows inseminated in spring (40.4%), fall (41.4%) and winter (51.7%) (P<0.05). Conclusions: PGF2α could treat severe clinical endometritis in dairy cows with corpus luteum in comparison with other treatments.

The influence of the most important parameters on the service life of reinforced asphalt overlay with geogrid materials in bending mode was examined by employing the Taguchi method and analysis of variance techniques. The objectives of this experiment was to investigate the effects of grid stiffness, tensile strength, coating type, amount of tack coat, overlay thickness, crack width and stiffnesses of asphalt overlay and existing asphalt concrete on propagation of the reflection cracking. Results indicate that the stiffnesses of cracked layer and overlay are the main significant factors that can directly improve the service life of an overlay against the reflection cracking. Generally, glass grid is more effective in reinforced overlay than polyester grid. Effect of crack width of the existing layer is significant when its magnitude increases from 6 to 9 mm.

We have investigated the effect of zinc oxide as a photocatalyst and durable flame-retardant on cellulosic fibers. Zinc oxide nanocrystals were successfully synthesized and deposited onto cellulosic fibers using sol-gel process at low temperature. The samples were characterized by means of several techniques such as scanning electron microscopy, transmission electron microscopy, diffuse reflectance spectroscopy, X-ray diffraction and thermogra- vimetric analysis. The photocatalytic activity was tested by measuring the photodegradation of methylene blue under UV-Vis illumination. Moreover, flame-retardancy was tested by vertical flame spread test. The optimum add-on value for donating flame-retardancy onto cellulosic fabric was obtained to be in the range of 15.24 to 23.20 g of the ZnO per 100 g of fabric. Thermogravimetric analysis of pure and flame-retarded samples were accomplished and discussed. The results obtained are in agreement with Wall effect theory and Coating theory. The originality of this work on introducing photoactive flame-retarded fibers is highly valuable for industrial implementation.

This survey was conducted to evaluate the impact of virgin olive oil nanoemulsion(ONE) combined with ajowan(Carum copticum) essential oil(AEO) on quality of lamb loin under refrigerated condition. The treatments were control, ONE, ONE + 1% AEO, and ONE + 2% AEO. The treatments caused a delay in growth of mesophilic and psychrotrophic bacteria, Enterobacteriaceae, and lactic acid bacteria during chilled storage. The increasing rate of total volatile nitrogen content, lipid and protein oxidation, metmyoglobin formation, and color deterioration was more retarded in treatment groups. The treatments including ONE + 1% AEO and ONE + 2% AEO were more efficient than ONE alone to delay microbial flora growth, slow down oxidative processes, and improve color in the loins. According to the results of microbial, chemical, and sensory parameters, shelflife of lamb loins was 4 days in control, 8 days in ONE, and at least 16 days in ONE + 1% AEO and ONE + 2% AEO groups. In conclusion, combination of ONE and AEO is appropriate as natural preservative to extend the shelflife of lamb loins stored under chilled condition.

Vitality is a quality that makes a public space operational and attractive throughout the day in relation to ongoing activities. This parameter can be evaluated through measures such as collective people presence, mixed-use functions, diversity of activities, and other related supportive physical elements. The aim of this research is to evaluate women＇s communal life in terms of vitality measures within public spaces. The commercial setting of Isfahan’s traditional bazaar was selected as the study area. To enhance the credibility of the results, several data collection methods, for example, semi-structured individual interviews （n = 24）, semi-structured focused group interviews （five groups including 28 middle-aged women）, direct observation, snap photography, and unobtrusive behavioral observation of women in communal life within the selected study area, were employed. To analyze the collected data, qualitative content and descriptive analyses were used. Our results indicate that by increasing the vitality of a public space through its related measures, women＇s presence will grow, and through this growth, the quality of their communal life would be enhanced.
