جیہڑا چوٹ عشق دی کھا گیا

جیہڑا چوٹ عشق دی کھا گیا
اوہو پنڈ دکھاں دی چا گیا
جیہڑا توبہ کر پچھتا گیا
اوہ سوہنے رب نوں بھا گیا
جس درشن کیتا یاراں دا
اوہ سارے لطف اٹھا گیا
اس رب نوں وی پہچان لیا
جیہڑا اپنے آپ نوں پا گیا
تیرا ویکھ کے نظر چرا لینا
میرا جگر کلیجہ کھا گیا
جیہڑا پنڈ دکھاں دی پڑھ لیندا
دکھیاں وچ نام لکھا گیا
تیرا نام حنیف دا لے لینا
میری جندڑی نوں تڑفا گیا

The Big Shift: Examining Practices, Challenges, and Coping Mechanisms of Teachers and Students in Transitioning to Modular Distance Learning

In response to the COVID-19 pandemic threat, the Department of Education (DepEd) established the Basic Education - Learning Continuity Plan (BE-LCP) to allow students to continue their education and teachers to conduct instruction in a safe working and learning environment. As a result, DepEd implemented the distance learning approach, including Modular Distance Learning (MDL), for the School Year 2020-2021. This paper investigated the practices, challenges, and coping mechanisms of teachers and students involved in the implementation of the MDL in Schools Division of Laoag City. This qualitative research utilized semi-structured interview guide to collect data from 20 teachers and 20 learners from elementary, junior high and senior high schools. Using the phenomenological study, data were analyzed and organized into themes. The study's major themes revealed that teachers and students began familiarizing themselves with the features of MDL but encountered challenges such as printing, distribution, and retrieval of modules, as well as monitoring of student progress on the part of the teacher and answering overloaded activities on the part of the students. They claimed, however, that they have unique coping mechanisms in dealing with the identified challenges by resolving issues independently and seeking help from family and colleagues. Finally, the Modular Distance Learning Adoption Framework (MDLAF) was developed and validated for teachers and students to effectively adopt MDL. The researchers recommended that relevant scaffolding such as capacity building, counseling and instructional support be provided to both teachers and students to effectively adopt different learning modalities such as MDL.

Synthesis, Characterization and Application of Fluorescent Brightening Agents on Synthetic Fibers

Names like “Fluorescent Whitening Agents”, “Optical Brighteners” and “Optical Bleach” are all used to describe the product “Fluorescent Brightening Agents”, but the term “FBAs” is preferably used because it has been taken from Chemical Abstracts. FBA is an organic compound. Most commercially available fluorescent brighteners are stilbene based having symmetric or asymmetric structures. Symmetric compounds are derivatives of 4,4''-bis(1,3,5-triazinylamino)stilbene-2,2''-disulfonic acid prepared by the reaction of 1mole of 4,4''-diaminostilbene-2,2''-disulfonic acid with 2 mole of cyanuric chloride. Synthesis of asymmetric compounds is also more expensive than symmetric compounds that’s why asymmetric compounds never become commercially important. The change in structure will effect on solubility, substrate affinity and on other properties. In this research stilbene based FBAs were synthesized from reaction of 4,4''-diaminostilbene-2,2''-disulfonic acid with 2,4,6-trichloro-1,3,5-triazine and then substitution of different nucleophilic amines on triazine moiety yielded FBAs. Substitution of different electron donating, electron withdrawing and solubilizing groups on these nucleophilic amines has great effect on properties of FBAs. The newly synthesized FBAs were characterized by UV-Visible, IR, Mass and 1H-NMR spectral data and applied on polyamide and cotton fabrics. All FBAs were light yellow in color. The performance of these FBAs was evaluated by different fastness measurements. All FBAs showed fastness grating in the range of 4-5 that is good quality performance. The color of FBAs were characterized by color co-ordinates L*, a*, b*, which in turn provide very powerful tool of objective color measurement, practiced in a modern industrial world. 3D-QSPR technique with the help of CoMFA model was applied on our synthesized FBAs.In this research we correlate CoMFA model with the absorbtivity of FBAs. A negative correlation has been observed because FBAs had low value of absorbtivity. The reason behind that is FBAs are light colored compounds they do not form covalent linkage with the fiber as like reactive dyes. They just adsorb on the fiber that’s why they had low value of absorbtivity.
