This study assessed the relationship between the practices, challenges and opportunities among School Resource Quality Assurance Team (SLRQAT) members of City Schools Division of Cabuyao when crafting e-learning materials during the school year 2021-2022. Three hundred ninety-eight (398) public elementary and secondary teachers were the respondents of the study. The researcher utilized the descriptive-correlational research design and self- made questionnaire to assess and measure the variables under study. The statistical tools used to analyze the data gathered were Mean, Standard Deviation, Pearson r and Multiple Linear Regression Analysis. Findings revealed that the profile of the respondents moderate the practices, opportunities and challenges of the SLRQAT members. While, the extent of practices and challenges among SLRQAT were moderated by such profile of the respondents. To ensure a more efficient output, recommendations were suggested based from the findings of the study regarding crafting e-learning materials.

PURPOSE: This review is focused on radium and radionuclides in its decay chain in honor of Marie Curie, who discovered this element. MATERIALS AND METHODS: We conglomerated current knowledge regarding radium and its history predating our present understanding of this radionuclide. RESULTS: An overview of the properties of radium and its dose assessment is sown followed by discussions about both the negative detrimental and positive therapeutic applications of radium with this history and its evolution reflecting current innovations in medical science. CONCLUSIONS: We hope to remind all those who are interested in the progress of science about the vagaries of the process of scientific discovery. In addition, we raise the interesting question of whether Marie Curie’s initial success was in part possible due to her tight alignment with her husband Pierre Curie who pushed the work along.

In H-2S mice, the administration of mercuric chloride results in the development of antinucleolar autoantibodies. These mice represent a valuable model to study the role of environmental factors in the development of systemic autoimmunity. We have obtained seven antinucleolar mAb from mercury-injected A.SW mice and characterized their specificities and V genes. All mAb immunoprecipitate the U3 and U8 ribonucleoprotein particles (RNP) and some (but not all) react with fibrillarin, the only currently characterized protein component of mammalian nucleolar RNP. Several VH and V kappa genes are recurrently used by these antinucleolar RNP mAb and their H chain CDR3 segments contain several acidic residues that may be important for binding to the cationic proteins composing the nucleolar RNP. Our results support the concept that in H-2S mice administration of mercury induces a specific loss of tolerance to nucleolar RNP.

Information, as we all know, is an asset. But like most other assets, it conveys no benefit until it is put to use. Land is of no benefit unless you cultivate it, or build on it, or sell it. Diamonds may be a girl's best friend but, locked in a bank, they don't do anything for her except, perhaps, provide the warm feeling of potential benefit.

Aris examines user worries and concerns, both business related ands technology related. A key issue is how users can use IT effectively to help gain competitive edge for their businesses. Aris also explores why IT is taken up faster in some industries rather than others. A significant factor is the relationship between top management and IT, and Aris dwells on what the ideal relationship should be. On the technology front, Aris identifies two main battle grounds for users: standards and software.
