M-Learning in education during COVID-19: A systematic review of sentiment, challenges, and opportunities.

The flexibility and relatively low cost of mobile devices make educational systems more accessible for learners and educators worldwide. When incorporated with the internet, it creates a better learning environment than the conventional classroom lecture. Many studies have been done to shed insight into the existing state of mobile learning (M-learning) studies.

Adaption of distance learning to continue the academic year amid COVID-19 lockdown.

This work investigates the use of distance learning in saving students' academic year amid COVID-19 lockdown. It assesses the adoption of distance learning using various online application tools that have gained widespread attention during the coronavirus infectious disease 2019 (COVID-19) pandemic. Distance learning thrives as a legitimate alternative to classroom instructions, as major cities around the globe are locked down amid the COVID-19 pandemic.

Conventional to online education during COVID-19 pandemic: Do develop and underdeveloped nations cope alike.

Background: Educational institutes around the globe are facing challenges of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Online learning is being carried out to avoid face to face contact in emergency scenarios such as coronavirus infectious disease 2019 (COVID-19) pandemic. Students need to adapt to new roles of learning through information technology to succeed in academics amid COVID-19.

Analyzing situational awareness through public opinion to predict adoption of social distancing amid pandemic COVID-19.

COVID-19 pandemic has affected over 100 countries in a matter of weeks. People's response toward social distancing in the emerging pandemic is uncertain. In this study, we evaluated the influence of information (formal and informal) sources on situational awareness of the public for adopting health-protective behaviors such as social distancing.

Evaluation of freeze-dried human sera as a novel approach for ATR-FTIR spectroscopic analysis as compared to conventionally used thin dry film sera.

Objective: Evaluation of the diagnostic potential of freeze dried sera in comparison to thin dry film analysis for recording ATR-FTIR spectra.

Results: For this purpose, we compared our novel sample preparation technique i.e.

Identification of new spectral signatures from hepatitis C virus infected human sera.

Hepatitis C virus (HCV) infection is one of the leading causes of morbidity and mortality worldwide. Mortality linked with HCV infection can be lowered with effective and prompt diagnosis in early stages of infection. In this study potential of Raman spectroscopy to differentiate between healthy and HCV infected serum samples was investigated.

Raman spectroscopy based differentiation of typhoid and dengue fever in infected human sera.

This study investigated the potential of Raman spectroscopy, to differentiate between two different types of human pathological conditions with some symptom similarity; typhoid and dengue. Raman spectra were recorded from 20 Salmonella Typhi infected and 22 dengue virus (DENV) infected sera samples using laser wavelength 785 nm. When Raman spectrum (540 to 1830 cm) of serum samples was compared it showed significant variations.
