Perovskite-type membrane Ba0.5Sr0.5Ce0.9Y0.1O3-? (BSCY) was successfully synthesized by liquid citrate method. The phase structure of the powder was characterized by X-ray diffraction (XRD). Scanning electron microscopy (SEM) was used to characterize microstructures of the membrane sintered under various conditions. SEM results showed that increasing in sintering temperature, formed dense membrane with clear grains. XRD results for BSCY membrane that sintered in 1150 °C indicated single phase perovskite structure with orthorhombic configuration, and SEM results showed dense structure with clear grain size which is suitable for permeation tests. Partial substitution of Sr with Ba in SCY structure improved the hydrogen permeation flux through the membrane due to the larger ionic radius of Ba 2+ . BSCY membrane shows high hydrogen permeation flux of 1.6 ml/min.cm 2 at 900 °C and partial pressure of 0.6.
24 Teachers’ Thinking of one’s Bad Impact away from Tobephobia on the Thoughts and you can Business Satisfaction
The goal of this research was to read the the fresh new the amount away from educators experiences off tobephobia (TBP) within their heterogeneous classrooms and you will just what impression that it had to their thinking and you will jobs fulfillment. The brand new expansive and you will consistently altering demands to own top quality and you can equal training for everyone students inside academic enterprises which have minimal info connotes your effects of TBP cannot be just overlooked because becoming low-existent regarding instructional ecosystem. Since this decimal research suggests, teachers hating work which have reasonable requirement, diminished desire within their workplace and you will pessimism, lead to the reduced care about-admiration. If you have pessimism in the workplace, then the teams mind-esteem commonly inevitably become low, since discussed of the 97.1% of your own participants within research. Self-value is actually a professional sign out of if or not employees are happy or not within perform and most this new respondents from inside the this study assented one to their enjoy from TBP adversely influenced to your the https://sugardaddydates.net/sugar-daddies-usa/ca/san-diego/ worry about-regard. And therefore, this exploratory data firmly indicates that productivity in the office try yourself connected to the personnel expectations, self-depend on in addition to their worry about-regard. Making it inconceivable for teachers become energetic in their typical classrooms if its genuine top-notch issues, anxiousness, and you may classes pressures are not properly handled. It empirical research results in all of our education towards TBP since it demonstrably traces some of the knowledge conditions that we are grappling which have and always experience in our very own schools contained in this 100 years. Hence, it’s imperative that tobephobic enjoy off teachers are not just reported, but appropriately treated with associated step because of the all stakeholder of the studies in order for our teachers thoughts and you may employment satisfaction requires is completely taken care of.
23 A four-Season Examination of Thyroid gland Carcinoma within the Hail Area: Improved Frequency
Record and Objective: In the most common aspects of the world, new occurrence out of thyroid gland cancer could have been increasing during the last ten years, mainly due to a combination of very early recognition of the neoplasm as a result of delicate steps and enhanced people connection with rays and you will unrecognized carcinogens. Methods: Instances of thyroid cancer tumors was basically retrieved on the malignant tumors registry at Queen Khalid Healthcare from inside the period of . Many years, intercourse and you will histopathologic items have been filed. Results: Thyroid carcinoma rated because the next typical malignancy in females (25%) once breast cancer (31%). They constituted 20.8% of the many recently identified cancer circumstances. For boys, it ranked the fresh cuatro th types of most cancers once gastrointestinal disease, lymphomas and you may flaccid tissue sarcomas. Mean decades for females and men was 38.seven +/- 13.dos and you will +/- eleven.5 years, correspondingly, and the difference between both communities try mathematically tall (p worthy of = 0.0001). Fifty-five (82%) was papillary carcinomas and ten follicular version off papillary (FVPC), and you can 7 papillary small carcinomas (PMC) as well as 2 tall phone/oncocytic variations. Follicular carcinomas constituted a couple (step 3.1%), if you are several (step 3.1%) was anaplastic, as well as 2 (step 3.1%) was medullary. Conclusion: Thyroid gland cancers chance when you look at the Hail try ranks since the 2 nd most frequent women most cancers just like most other nations on Empire. Yet not, that it highest chance contrasts having reduced rates in the world.
