Worldwide, a lot of education programs offer new forms of education that are frequently supported by information and communication technology (ICT) to cater to young minds. E-learning in particular has been adopted by educational institutions all over the world and it is being used as a part of “blended learning” where it is incorporated into systems along with traditional classroom learning. Nowadays, it has become more relevant than ever due to the COVID-19 pandemic that the world is facing. Although these systems differ from classroom learning, they allow easy communication among teachers and students at any time necessary and provide an entire repository for students to use. For teachers, it acts as an environment for creating courses, assignments, giving feedback and grading students. In this paper, two such E-learning platforms namely Moodle and Google Classroom are compared and contrasted based on their usability and simplicity.</p> Sempavalan Vasanth C. S.

Many chemical substances with antimicrobial properties, are effective against microorganisms causing dental caries. The objective of this study was to check the antimicrobial efficacy of some toothpastes&nbsp; found in Enugu metropolis, Nigeria more specifically against clinically isolated <em>Streptococci mutans</em>. The antimicrobial efficacy of different brands of toothpastes marketed in Enugu metropolis&nbsp; was assayed against <em>Streptococci mutans</em> using the agar well diffusion method. The clinical <em>Streptococci mutans</em> used for this study were taken from carious lesions of patients that&nbsp; attended the clinic at Federal College of Dental Therapy and Technology, Trans Ekulu, Enugu, Nigeria and were isolated and cultivated using traditional laboratory methods. The present&nbsp; study has shown that toothpaste which contains mint extract as herbal constituent and sodium fluoride had the highest antimicrobial activity, followed by toothpastes containing only sodium monofluorophosphate. Herbal toothpaste with mint can be a safe and effective alternative in the prevention of dental caries.</p> Eze E. Ajaegbu Calister U. Ezeh Adaobi J. Dieke Adaora L. Onuora Jane I.

Melting point and Fourier transform infrared spectrophotometer (FTIR) methods were used to confirm the purity and identity of the artemether used in the study. The derivatization process was carried out between 100 µg/ml of the artemether and 500 µg/ml of p-nitroaniline in different molarities (0.5, 1, 2, 3, 4, 5M) of HCl at 60ºC for 45 mins. The melting point ranged between 86-89ºC and the FTIR determination revealed a band at 3169.978 cm-1 due to O-H stretching vibration and C-H stretching at 2996.039 cm-1. There was no observed difference in wavelength between the p-nitroaniline spectrum and the spectra of the derivatized products in different molarities of HCl. p-nitroaniline may not be a proper derivatization reagent for the assay of artemether in pure or dosage form.</p> Jane I.

The established approach to the evaluation of ovarian function and endocrine disorders in the woman is based on serial biochemical analyses of hormones, such as estrogen, progesterone, luteinizing hormones and their metabolites. This study analyzed the ratio of parabasal, intermediate and superficial cells in comparison with the presenting hormones. The biochemical analyses can be effectively supplemented by the old-fashioned endometrial biopsies, or studies of endocervical mucus. In addition, the vaginal smear may sometimes provide useful information and has the advantage of being easy to obtain, rapidly evaluated, and inexpensive. Cytology is the study of cells collected by various means through microscopic examination. In the case of humans, the cytologic approach is particularly valuable if laboratories specializing in endocrine analysis are not readily available. The principle of the cytologic hormonal analysis is simple. The degree of maturation of the squamous epithelium of the female genital tract depends on steroid hormones, mainly estrogen. Various factors contribute to the fertility status of a woman. In the case of this study, age, abortion and use of contraceptives are the significant contributing factors (p &lt;0.05, t &gt;1.96).</p> Adepoju Paul Olusegun Solaja Anuoluwani Adeola Adediji Isaac Nabofa Williams Adepoju Victoria Feyikemi ##submission.copyrightStatement## 2020-10-06 2020-10-06 46 53 10.9734/air/2020/v21i1030251 Exposure to Excessive Sound Volume: A Major Challenge in the South-Western Nigeria Church Auditoria https://journalair.com/index.php/AIR/article/view/30252 <p>The study examines the exposure to excessive sound volume as a major challenge to grapple with in church auditoria in South-western Nigeria. This exposure to excessive sound has become a source of noise pollution and it is dangerous to human health. Data for this paper were gathered through participant observation of musical acoustics in worship auditoria using a Virtual Instrument; a Sound Pressure Level mobile application installed on a mobile phone for sound volume measurement. The equivalent noise level using A-weighting was taken for twenty minutes per day, this was observed for the three different worship services at different dates and time in each of the selected church auditoria during each worship service. The LAeq, T, of each musical session was calculated. Findings show that the worshippers are exposed to average noise levels of 90.29 dB (Threshold of Pain) at every worship service which is higher than the recommended 60dB for normal human ear by World Health Organization (WHO). It was also observed that all the selected church auditoria lack appropriate acoustic treatment which led to sound reflections and severe echo. The paper concludes that the culture of noise pollution has become a social phenomenon in the Nigerian society especially, in church auditoria where loud musical sound is arrogated to power and domination of space. This paper recommends that acceptable optimal standards for sound production either in enclosures or in open spaces be emphasized by the Nigerian local, state and federal governments to effectively control noise for human and societal wellbeing.</p> Solomon Ikibe Olatunbosun Samuel Adekogbe ##submission.copyrightStatement## 2020-10-15 2020-10-15 54 65 10.9734/air/2020/v21i1030252
