The transition of C. albicans from unicellular yeast form to filamentous form i.e., pseudohyphae and hyphae is referred to as morphogenesis. C. albicans has the ability to respond to environmental conditions and accordingly changing its cell morphology. Three main morphological forms of C. albicans are unicellular yeast, pseudohyphae and hyphae. The effect of different growth media (Horse serum medium, RPMI-1640, MSGB), incubation temperatures (34˚C, 37˚C, 40˚C) and pH values (5.4, 6.4, 7.4) on germ tube production by C. albicans was evaluated. (...) Horse serum medium noticeably promotes filamentation while RPMI-1640 medium shows moderate filamentation and MSGB media shows moderately low filamentation. The germ tube of C. albicans developed early in 1.5 hr at high temperature i.e., 40˚C. Incubation temperature of 37˚C was associated with highest germ tube formation while 34˚C shows low filamentation. A pH of 5.4 also induces low filamentation, pH 6.4 gives moderately lower than pH 7.4. A pH of 7.4 was best suited for germ tube induction. The peak of mycelium production appears between 1.5 and 6 hr after inoculation of C. albicans culture. These results suggested that environmental factors are important in selectively favoring yeast or hyphal form, most important being the growth medium, incubation temperature and external pH value.

The ontological analysis of concrete particulars deals with the relationship between concrete object and their attributes. Both Peter Simons' Nuclear Theory and Aristotelian Substance Theory may present an acceptable explanation for the following three problems: Identity of Indiscernible, Excessive Necessitism and Change. In spite of the superiority of these two theories over the other theories, each has problems need to be addressed. Aristotelian theory does not seem to be very successful in showing that the spices (kinds) are unchangeable or at (...) least does not explain it. Simmons's theory also returns to Aristotelian theory. While outlining the challenges to any theory, the final suggestion of the paper is that with inspiration of Simmons' theory and introducing a relation between the generalities (universal Whatness), create a modification in Aristotelian theory to overcome the challenge of the irreductive challenge of Species (kinds) Simons' theory, in some sense, collapses back to Aristotelian Theory.

Research in second language learning has identified the absence of metacognition among learners as one of the major problems contributing to students’ inability to comprehend listening texts. Moreover, the shift to remote teaching due to COVID-19 has made it more crucial for teachers and learners to adapt to new modes of teaching and learning. This accentuates the need for effective listening strategy instruction. This study conducted at a university in Oman, is unique in two ways: first, it seeks out teachers’ (...) perceptions of metacognitive strategy instruction in remote teaching; and second, the intervention in the form of explicit metacognitive strategy instruction is offered online. This paper presents the findings of the study, which focused on the following: teachers’ perception of students’ listening difficulties; teachers’ perceptions of metacognitive strategies and their explicit instruction; the role of metacognitive strategy awareness and instruction in improving student participation and skills in listening; challenges encountered in teaching listening during remote teaching; and overcoming challenges of teaching metacognitive strategies in remote teaching. This mixed-method study collected data through questionnaires and interviews with 10 faculty members and 75 students. The findings show that teachers face several challenges, such as time limitations, shortened semesters, unfamiliar coursebook contexts, and assessment practices. For strategy instruction, teachers utilized collaborative lesson planning and resources and virtual flipped classrooms, among others. We conclude that metacognitive strategy instruction can provide better scaffolding during listening instruction and recommends further exploration of students’ use of metacognitive strategies in other academic contexts.

Abstract: English language teaching is very important because of the global status of English. English language teaching is a process that requires great efforts on the part of all the participants. Classroom interactions, activities, textbooks are the most important elements of teaching process for the aims and objectives of a course. Main objective of this study is to discover English language teaching skills in primary schools of union council Kumb Taluka Kotdiji, District Khairpur Mir’s. The Questionnaire was prepared for teachers (...) to explore the different aspects of teaching English skills and teachers’ skills, (Training, teacher qualifications regarding English, English teaching methodologies). The questionnaire identifies teacher training and instructional materials. A sample of 20 teachers (both male and female) were selected from different schools of union council Kumb Taluka Kotdiji, District Khairpur Mir’s. The data obtained was tabulated and analyzed by the percentage. (shrink)

I have read the article "Retract or be damned: a dangerous moment for science and the public" by Kamran Abbasi. The article discusses the growing problem of retractions in scientific literature, and argues that this is a threat to the integrity of science and the public's trust in science.
