This journal seeks to disseminate the work of emerging students who focus on scientific/technical content, regardless of their academic discipline. <em>Adv. J. Grad. Res.</em> publishes research carried out by graduate students and young researchers (Bachelor's degree students and Master's degree students) that sound scientifically and technically valid. This journal will serve as a global platform to broadcast new research initiatives being carried out by today's brightest youths as part of their graduate project.<br />Advanced Journal of Graduate Research is published by AIJR publisher (India) and registered with CrossRef with doi: 10.21467/ajgr and ISSN of this journal is 2456-7108 [online].</p> AIJR Publisher en-US Advanced Journal of Graduate Research 2456-7108 <div id="copyrightNotice">Author(s) retains full copyright of their article and grants non-exclusive publishing right to this journal and its publisher <a title="About AIJR Publisher" href="https://aijr.org/about/about-aijr/" target="_blank" rel="noopener">AIJR</a> (India).

Mobile phones are indispensable gadgets with a wide range of applications. However, there are potential risks associated with its usage in terms of radiofrequency radiation. The objective of this study was to evaluate the knowledge of radiation and its biological adverse effects caused due to the usage of mobile phones among students and working professionals. An online awareness survey was conducted during the COVID-19 pandemic among 351 participants using Google forms. The questionnaire was disseminated to the WhatsApp groups of students and working professionals and the data was statistically analysed. Among the 351 subjects, 72% of the respondents used their mobile phones for more than 4 hours per day. However, less than 20% were fully aware of mobile phone radiation being listed in the possible carcinogen list by the World Health Organization (WHO). In addition, only half of the respondents considered the Specific Absorption Rate (SAR) value and information on radiation emission while purchasing a new phone. To conclude, the need for awareness of potential hazards associated with the mobile phone radiation seems crucial, especially during this time when everyone in the world and especially school and college students are highly dependent on mobile phones.</p> Joshua Paul Anandi Shivaram Panchami P Bhumika Patel Devi Jaikrishnan Wilner Martinez-Lopez Radha Saraswathy Copyright (c) 2022 Joshua Paul, Anandi Shivram, Panchami P, Bhumika Patel, Devi Jaikrishnan, Wilner Martinez-Lopez, Radha Saraswathy http://creativecommons.org/licenses/by-nc/4.0 2022-03-21 2022-03-21 12 1 1 10 10.21467/ajgr.12.1.1-10 Association of Intrinsic Factors with Non-contact Injury Prevalence of Front Foot Knee Pain Among First Class Fast Bowlers in Colombo Division https://journals.aijr.org/index.php/ajgr/article/view/4592 <p><strong>Background: </strong>Cricket is one of the most popular sports in Sri Lanka. Both intrinsic and extrinsic injury prevention and increase performance are of cardinal importance to a fast bowler to reach optimal performance. Intrinsic prevention methods may protect the fast bowler against too high level of stress experienced during bowling. In this study we aimed to assess the incidence of front foot knee pain and the associated intrinsic risk factors among first class cricket fast bowlers, to come up with recommendations to improve training regimes to prevent non-contact injury.</p> <p><strong>Method: </strong>Descriptive Cross-Sectional study was conducted with 30 fast bowlers with front foot knee pain. Severity of knee pain was measured by using knee evaluation form. Q angle, Hip internal rotation were measured using a modified goniometer. Quadricep and hamstring muscle strength were measured by cuff adapted sphygmomanometer. Ankle dorsiflexion was measured by Lunge Test.</p> <p><strong>Results:</strong> An insignificant, positive correlation in Ankle dorsiflexion (p=0.780, r=0.053), hip internal rotation (p=0.194, r=0.244), and quadriceps hamstring muscle strength ratio (p=0.952, r=0.012) of the fast bowlers with front foot knee pain was observed. Also, there was an insignificant negative correlation between quadriceps angle (p=0.827, r=-0.042) and front foot knee pain.</p> Sameera Senanayake Charith Kandambi Seedevi Gamage Kaushalya Hettiarachchige Nisansala Copyright (c) 2022 Sameera Senanayake, Charith Kandambi , Seedevi Gamage Kaushalya, Hettiarachchige Nisansala http://creativecommons.org/licenses/by-nc/4.0 2022-03-23 2022-03-23 12 1 11 19 10.21467/ajgr.12.1.11-19 Morphometric and Heavy Metals Accumulation in the Muscles of Five Demersal Seafoods Sampled in Nigerian Coastal Waters https://journals.aijr.org/index.php/ajgr/article/view/4059 <p>This study examined the morphometric and heavy metals accumulated in the muscles of five demersal sea-foods: <em>Parapenaeopsis atlantica, Penaeus monodon, Penaeus notialis</em>, <em>Portunus validus</em> and <em>Cynoglossus browni </em>from Nigerian coastal waters. 506 deep frozen samples (at -20<sup>0</sup>C) each of the five demersal species were taken upon arrival from thirty-one (31) industrial fishing trawler vessels owned by a private fishing company in Lagos, Nigeria. Samples were thawed and morphometric characteristics such as weight, total length, standard length, body depth and carapace length/head length were measured. The heavy metals [Lead (Pb), Iron (Fe), Zinc (Zn), Arsenic (As), Mercury (Hg) and Cadmium (Cd)] were analyzed using 210 Atomic Absorption Spectrophotometer (AAS). The morphometric characteristics revealed that <em>P. atlantica</em> and <em>P. notialis</em> showed no significant difference in mean values only for their carapace lengths while both species showed statistically different observations for other variables. The order of the heavy metals mean concentration was Zn&gt;Fe&gt;Pb. As and Cd had relatively very low values of &lt;0.01mg/kg while Hg was not detected in all samples. The findings of this study revealed high and increasing values of Zinc in all five demersal species under consideration exceeding maximum limits for FAO/WHO and NIS (Nigerian Industrial Standard). The zinc value of the species appears to be contained in this order; <em>P. notialis</em> &gt; <em>C. browni</em> &gt; <em>P. monodon</em> &gt; <em>P. validus &gt;P. atlantica</em>. However, Iron value for <em>P. atlantica</em> is above the limit of FAO/WHO. Consumption of the species invariably leads to a rise in the Zinc contents in diets and in humans which may cause gastrointestinal disorders, kidney and liver abnormal functioning especially in infants and children while other heavy metals contained in the species do not pose a threat to human health.</p> Oluwafemi Paul Fajana Akintade Adeboyejo Copyright (c) 2022 Oluwafemi Paul Fajana, Akintade Adeboyejo http://creativecommons.org/licenses/by-nc/4.0 2022-03-23 2022-03-23 12 1 20 35 10.21467/ajgr.12.1.20-35
