International Journal of Science and Engineering Invention http://ijsei.in/index.php/ijsei <p>The International Journal of Science and Engineering Invention (IJSEI) is an international open access multidisciplinary peer-reviewed journal and this leading international journal publishes scholarly papers and review articles on all aspects of the science, engineering, information technology, medical sciences and social studies of science.&nbsp;The principal mission of the journal is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.</p> <p><strong style="font-family: Arial; font-size: 18px; font-weight: 400; color: #333333;">IJSEI Publication Ethics Statement</strong></p> <p>IJSE takes the responsibility to enforce a rigorous peer-review together with strict ethical policies and standards to ensure to add high quality scientific works to the field of scholarly publication. Unfortunately, cases of plagiarism, data falsification, inappropriate authorship credit, and the like, do arise. IJSEI takes such publishing ethics issues very seriously and our editors are trained to proceed in such cases with a zero tolerance policy. To verify the originality of content submitted to our journals, we use iThenticate to check submissions against previous publications.</p> <p><strong style="font-family: Arial; font-size: 18px; font-weight: 400; color: #333333;">Copyright / Open Access</strong></p> <p><strong>Open Access</strong> - free for readers, with article processing charges (APC) paid by authors or their institutions.</p> <p><strong>Rapid publication:</strong> manuscripts are peer-reviewed and a first decision provided to authors approximately 20 days after submission; acceptance to publication is undertaken in 10 days.</p> <p><strong>Recognition of Reviewers: </strong>reviewers who provide timely, thorough peer-review reports receive vouchers entitling them to a discount on the APC of their next publication in any IJSEI journal, in appreciation of the work done.</p> <p>Articles published in <em>IJSEI</em> will be Open-Access articles distributed under the terms and conditions of the Creative Commons Attribution License (CC BY).

The aim of the application of ICT in the management of auxiliary machinery is successful organization and better use of resources while ensuring the planned work of basic machinery (excavator, stackers) at the excavation of waste rock and coal.</p> <p>&nbsp;</p> <p>This paper presents the application of ICT in auxiliary machinery on open coal pit mines with the corresponding system and software solutions for the management of machines and vehicles. The results of the application provide the parameters of operation (position, trajectory, operating time, fuel consumption ...), machines and vehicles from operational work, in real time. This ensures the successful management of the operation of machines and vehicles in real time.</p> Vladimir Simeunuvic, Radivoje Mitrovic, Prof. Dr ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 http://ijsei.in/index.php/ijsei/article/view/87 Wed, 05 Sep 2018 11:15:04 +0000 Distribution of Phytochemicals and Some Anti-nutrients in Selected Edible Mushrooms in Ekiti State, Nigeria http://ijsei.in/index.php/ijsei/article/view/96 <p>The present study was carried out to determine the phytochemical and anti nutritional composition of some selected edible mushrooms collected in Ekiti State, Nigeria such as <em>Pleurotus sajor-caju</em>, <em>Termitomyces robustus</em>, <em>Lentinus squarosullus</em>, <em>Termitomyces microcarpous</em>, <em>Termitomyces clypeatus</em>, <em>Lentinus tuber-regium</em> and <em>Polyporus </em>sp. The results of phytochemical analyses revealed the presence of phytochemicals such as alkaloids (0.03-0.17%), saponin (0.03-0.12%), total phenols (0.12-4.32%), flavonoids (0.20-6.04%) and tannins (0.04-2.60%). The least concentration of all the phytochemicals was found in <em>Polyporus </em>sp. Results of anti nutrient screening revealed the presence of phytate (0.17-0.34mg/g), oxalate (1.87-4.04mg/g) and cyanide (0.05-0.27mg/g). Furthermore, results revealed significant differences in the phytochemical as well as anti nutritional composition of the mushrooms though some species had similar compositions. The obtained values of phytochemicals and anti nutrients were significantly lower in all the mushroom species compared to their toxic levels according to World Health Organization stipulated safe limits. Thus, the study suggests that all the mushroom species are very safe for consumption while the presence of alkaloids, saponins, phenols and flavonoids indicate medicinal potentials. Hence, screening and characterization of the secondary metabolites are required.</p> Adedeji Olayinka Adebiyi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 http://ijsei.in/index.php/ijsei/article/view/96 Wed, 05 Sep 2018 00:00:00 +0000
