Perovskite-type membrane Ba0.5Sr0.5Ce0.nineY0.step oneO3-? (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’ Attitudes of one’s Negative Impression off Tobephobia to their Feelings and you will Business Pleasure
The goal of this research were to take a look at the the the amount out of coaches experiences away from tobephobia (TBP) within their heterogeneous classrooms and exactly what effect this had to their thinking and you may business pleasure. The fresh new inflatable and consistently modifying means getting high quality and equal education for everyone children during the academic organisations which have limited information connotes your outcomes of TBP cannot be just forgotten while the are non-existent on the educational ecosystem. As this decimal data reveals, educators disliking work having low standards, insufficient motivation within their work environment and you will pessimism, produce their reasonable thinking-regard. When there is pessimism at the office, then the employees notice-esteem often usually getting reasonable, while the discussed from the 97.1% of respondents within this research. Self-admiration was a reputable sign of whether or not workers are delighted or not in their efforts and the majority of the fresh new respondents in this research conformed one to their event off TBP negatively influenced with the its mind-regard. Which, which exploratory data firmly shows that yields at the office is myself linked to the professionals traditional, self-rely on in addition to their mind-regard. So it is inconceivable to possess instructors become effective in their typical classrooms if the the genuine elite concerns, stress and anxiety, and you can program demands are not properly treated. So it empirical study results in all of our degree toward TBP because it clearly contours a number of the training conditions that we have been wrestling having and always experience in our very own schools within century. Ergo, it is vital the tobephobic experiences away from instructors are not only reported, however, rightly treated with associated action from the every stakeholder regarding the degree so all of our coaches feelings and you may business satisfaction means are fully out-of-the-way.
23 A several-12 months Study of Thyroid gland Carcinoma for the Hail Part: Enhanced Incidence
History and you will Purpose: For the majority areas of the country, this new chance away from thyroid cancer tumors might have been increasing over the past years, mainly due to a combination of very early identification of the neoplasm as a result of sensitive and painful methods and you can enhanced society contact with light and you will unrecognized carcinogens. Methods: Cases of thyroid cancer tumors was in fact recovered in the malignant tumors registry during the King Khalid Healthcare in the months from . Decades, intercourse and you may histopathologic designs have been submitted. Results: Thyroid gland carcinoma rated because next common malignancy in females (25%) shortly after breast cancer (31%). It constituted 20.8% of all the recently recognized cancers instances. As for people, they ranked this new 4 th types of cancer malignancy once intestinal cancer, lymphomas and you will mellow tissue sarcomas. Mean decades for ladies and you will people are 38.eight +/- thirteen.dos and you will +/- eleven.5 years, respectively, and difference in both groups try mathematically high (p really worth = 0.0001). Fifty-five (82%) was indeed sugar baby in Kansas City MO papillary carcinomas as well as 10 follicular variation out of papillary (FVPC), and you will eight papillary mini carcinomas (PMC) and two high phone/oncocytic versions. Follicular carcinomas constituted a couple (3.1%), if you find yourself two (3.1%) have been anaplastic, and two (step three.1%) were medullary. Conclusion: Thyroid cancers incidence inside the Hail is positions as the 2 nd common lady most cancers exactly like almost every other countries from the Empire. But not, which higher chance contrasts which have far lower prices globally.
