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.

Thermoluminescent characterization and defect studies of graphite-rich media under high dose neutron exposure.

Thermoluminescence (TL) materials have a broad variety of uses in various fields, such as clinical research, individual dosimetry, and environmental dosimetry, amongst others. However, the use of individual neutron dosimetry has been developing more aggressively lately. In this regard, present study establishes a relationship between the neutron dosage and the optical property changes of graphite-rich materials caused by high doses of neutron radiation.

Design and Gamma-Ray Attenuation Features of New Concrete Materials for Low- and Moderate-Photons Energy Protection Applications.

We aimed, in this investigation, to prepare novel concretes which can be used in gamma-ray shielding applications. The experimental approach was performed using a NaI (Tl) detector to measure the concrete's shielding features for different energies, ranging from 0.081 MeV to 1.

Effect of Aloe vera and clove powder supplementation on growth performance, carcass and blood chemistry of Japanese quails.

This study was aimed to assess the impacts of aloe vera (AV) and clove (Cv) powder supplementation on growth performance, carcass quality, blood biochemistry, and hematology of Japanese quails and studying the possibility of using them as alternatives to antibiotics growth promotors as a natural safe products. Four hundred, 7-d old mixed sex chicks were divided into 4 groups of 5 replicates 20 birds per replicate including (10 males and 10 females). Birds in the control group (T1) were fed a diet containing Enramycin (0.

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.

Impact of BiO modifier concentration on barium-zincborate glasses: physical, structural, elastic, and radiation-shielding properties.

Abstract: A sequence of BiO varying barium-zincborate (BZX) glasses with the chemical composition (60-) BO-20ZnO-20BaCO-BiO-0.5DyO (where  = 0, 5, 10, 15, 20, 25, and 30 in wt%) is fabricated by melt-quenching method. The fabricated samples were examined for the variation in physical, structural, elastic, and radiation-shielding properties with the BiO concentration.

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.

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.

Malignant myoepithelioma (MM) of parapharyngeal space provide both a diagnostic and therapeutic challenge. Malignant myoepitheliomas are rare tumour of salivary glands. Most occur in the parotid gland, few other sites of origin are described.

Relationships between cyclic AMP levels and lipolysis in fat cells after isoproterenol and forskolin stimulation.

Using the flask-incubated fat cell system, alterations in glycerol release (lipolysis) and cAMP accumulation were determined after incubation with isoproterenol or forskolin. These agents caused concentration-dependent increases in both cAMP accumulation and lipolysis. The maximum responses to forskolin for each variable were greater than the corresponding responses to isoproterenol.
