Perovskite-type membrane Ba_0.5Sr_0.5Ce_0.nineY_0.1O_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.

twenty-four Teachers’ Perceptions of one’s Bad Impact away from Tobephobia to their Emotions and you can Employment Pleasure

The purpose of this study were to check out the the fresh extent out-of instructors knowledge out of tobephobia (TBP) inside their heterogeneous classrooms and you may exactly what impact this got on their emotions and you will employment pleasure. The new inflatable and you can continuously modifying needs for quality and you will equal studies for everyone students within the informative organizations with restricted resources connotes the outcomes of TBP can not be only ignored once the getting non-existent throughout the informative environment. As this decimal data reveals, educators disliking their job with lowest standards, shortage of inspiration within place of work and you may pessimism, trigger their lowest self-respect. If you have pessimism in the workplace, then your professionals self-esteem usually usually become lower, once the talked about of the 97.1% of your own respondents in this investigation. Self-respect try a reputable sign out-of if or not employees are delighted or perhaps not in their jobs and the majority of the new participants inside the this study assented you to its feel away from TBP negatively impacted towards its mind-value. And that, so it exploratory research strongly demonstrates efficiency at work is individually attached to the professionals standard, self-believe and their self-admiration. So it is inconceivable getting coaches becoming active in their regular classrooms if their genuine elite inquiries, anxiety, and you will programs demands commonly effectively handled. Which empirical study leads to the training with the TBP because demonstrably contours a few of the training conditions that we are wrestling which have and constantly expertise in the universities within 100 years. Ergo, it’s essential that tobephobic feel off coaches commonly merely documented, however, correctly addressed with relevant step by the the stakeholder on the degree to ensure our coaches ideas and you will employment fulfillment need are totally off the beaten track.

23 A four-Seasons Examination of Thyroid Carcinoma in Hail Region: Increased Frequency

History and Purpose: For the majority regions of the world, new incidence away from thyroid gland cancer might have been increasing during the last decade, primarily because of a combination of very early identification of the neoplasm through sensitive and painful actions and you can enhanced population connection with radiation and you can unrecognized carcinogens. Methods: Instances of thyroid malignant tumors was recovered on malignant tumors registry at the Queen Khalid Healthcare for the period off . Years, gender and you can histopathologic types was basically registered. Results: Thyroid gland carcinoma ranked due to the fact second most common malignancy in females (25%) immediately after cancer of the breast (31%). It constituted 20.8% of all freshly identified malignant tumors instances. In terms of boys, it ranked the 4 th version of most cancers shortly after gastrointestinal disease, lymphomas and you may softer tissues sarcomas. Imply age for ladies and you will boys was 38.7 +/- thirteen.2 and you will +/- 11.5 years, correspondingly, together with difference in the 2 teams is statistically tall (p value = 0.0001). Fifty-four (82%) had been papillary carcinomas in addition to 10 follicular variant out of papillary (FVPC), and you can eight papillary micro carcinomas (PMC) and two extreme telephone/oncocytic versions. Follicular carcinomas constituted several (step 3.1%), if you’re a couple of (step three.1%) was basically anaplastic, as well as 2 (step 3.1%) had been medullary. Conclusion: Thyroid gland cancer tumors incidence when you look at the Hail are ranking just like the dos nd typical women most cancers like almost every other regions in the Empire. However, which higher frequency contrasts with much lower prices globally.
