Perovskite-type membrane Ba_0.5Sr_0.5Ce_0.nineY_{0.step one}O_3-? (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 your Negative Impact away from Tobephobia sugardaddy on their Thinking and you will Business Fulfillment

The purpose of this research was to check out the this new the amount of educators experience of tobephobia (TBP) within their heterogeneous classrooms and you may just what impression that it got on their attitude and you may employment satisfaction. New expansive and you can continuously switching means to possess quality and you may equal degree for everyone students in the academic enterprises with restricted tips connotes your negative effects of TBP can not be only neglected while the becoming low-existent regarding academic environment. As this decimal analysis shows, coaches loathing their job with low traditional, lack of inspiration inside their workplace and pessimism, bring about their low self-respect. When there is pessimism in the office, then staff worry about-regard will usually end up being lower, because the discussed from the 97.1% of your own respondents contained in this analysis. Self-esteem is a reliable sign out of whether employees are happier or not within operate and a lot of new participants when you look at the this research consented that the knowledge regarding TBP adversely affected for the their care about-regard. And that, that it exploratory studies highly suggests that returns in the office was directly attached to the staff requirement, self-depend on in addition to their care about-respect. So it is inconceivable to own instructors is energetic within typical classrooms if the its legitimate elite issues, anxiousness, and you can training challenges commonly acceptably addressed. That it empirical study leads to the degree towards TBP because clearly lines a few of the training issues that our company is wrestling with and constantly expertise in our very own colleges contained in this century. Therefore, it is essential your tobephobic skills of educators aren’t just recorded, however, correctly addressed with relevant action by the the stakeholder on the education in order for all of our educators feelings and you can employment satisfaction need try completely out-of-the-way.

23 A several-Season Study of Thyroid Carcinoma from inside the Hail Area: Increased Occurrence

History and you can Purpose: In most areas of the country, the new incidence out-of thyroid cancers might have been expanding over the past 10 years, generally due to a variety of early recognition of neoplasm through sensitive and painful actions and improved society experience of radiation and you may unrecognized carcinogens. Methods: Cases of thyroid gland disease was indeed recovered about cancer tumors registry on King Khalid Hospital in the period off . Ages, sex and you can histopathologic sizes was basically submitted. Results: Thyroid gland carcinoma ranked since the 2nd most common malignancy in females (25%) just after cancer of the breast (31%). They constituted 20.8% of all the recently recognized cancer times. As for people, they rated the fresh new cuatro th type of malignancy after intestinal cancers, lymphomas and flaccid tissue sarcomas. Indicate ages for ladies and you will men is 38.7 +/- thirteen.2 and you may +/- eleven.five years, correspondingly, and also the difference in both organizations try mathematically high (p really worth = 0.0001). Fifty-four (82%) was papillary carcinomas together with ten follicular variant out-of papillary (FVPC), and you can seven papillary mini carcinomas (PMC) as well as 2 tall phone/oncocytic variations. Follicular carcinomas constituted several (step 3.1%), when you find yourself a couple (step 3.1%) had been anaplastic, as well as 2 (step three.1%) was basically medullary. Conclusion: Thyroid disease occurrence for the Hail was ranking since dos nd popular people malignancy the same as most other countries about Kingdom. But not, that it higher occurrence contrasts that have far lower pricing around the globe.
