If we participate in disseminating and promoting scientific research at all levels of our society, offering the possibility of making the voice of researchers and professional experts heard, we believe that it will be beneficial for all of us (researchers, decision-makers, entrepreneurs and experts).</span></p> https://grrojs.clubforleaders.org/index.php/GRR/article/view/15 Micro – nutrients of red – billy tilapia (coptodon zillii) among different Egyptian water masses 2021-07-04T12:31:46-04:00 Hadeer SAIED hadeer_saied@science.suez.edu.eg <p>Fishes concentrate heavy metal from surrounding environment <br>inside their tissues. The study aims to determine the micro –<br>nutrient contents (Cu, Fe, Mn, Pb) of Coptodon zillii in Bardwail <br>Lagoon, Mediterranean Sea, Brackish Water Lagoon and Lake <br>Timsah. The results showed that the highest nutrients were in <br>Brackish Water Lagoon while the lowest ones in Mediterranean <br>Sea site. Considering to nutrients, the highest value was 36.2 <br>mg/ Kg of Fe while the lowest value was 0.57 mg/ Kg of Mn. <br>The study approved the high – nutrition value of Coptodon zillii<br>and healthy minerals content minerals among its flesh.</p> 2021-07-04T00:00:00-04:00 Copyright (c) 2021 https://grrojs.clubforleaders.org/index.php/GRR/article/view/16 Macro – nutrients of cichlid fishes in lake Timsah, Egypt 2021-07-04T12:43:05-04:00 Hadeer SAIED hadeer_saied@science.suez.edu.eg <p>Cichlid fishes are one of the highly economic fishes in Egypt. <br>The study aims to determine the macro – nutrient content for <br>(K, Na, P, Ca, and Mg) of (Oreochromis niloticus, Coptodon <br>zillii, Oreochromis aureus, and Sarotherodon galilaeus) in Lake <br>Timsah, Egypt. Among studied species, S. galilaeus possesses <br>the highest values of nutrients except Ca while O. niloticus<br>possesses the lowest values except P and Ca. For elements, <br>1057 mg/Kg of Mg was the highest while 36 mg/Kg of Ca was <br>the lowest. The conclusion is cichlid fishes have a high <br>nutritional value with remarkable differences among studied <br>species.</p> 2021-07-04T00:00:00-04:00 Copyright (c) 2021 https://grrojs.clubforleaders.org/index.php/GRR/article/view/10 The Role of Technologies in Relationship Management and Internal Marketing: a preliminary contribution 2021-07-04T11:06:34-04:00 Vasco RIBEIRO SANTOS vasco.ribeiro@islasantarem.pt Eduarda MENDES eduarda821@icloud.com Bruno SOUSA bsousa@ipca.pt Márcia GONCALVES marcia.goncalves@isag.pt Cláudia VELOSO cmv@ua.pt Isabel REIS isabel.reis@islasantarem.pt <p>The present study aims to understand the impact and the role of <br>technologies in a hospital context, and in relationships management from an <br>internal perspective (internal marketing).

This model will allow micro-grid prosumers to produce, consume and trade energy <br>deprived of any barrier. At present, such a system is not accepted because it requires the “collaboration” of <br>central energy distributors. In our solution, we visualize the use of a blockchain system with the support of <br>smart contracts to provide decentralization. The energy is sent to the central energy storage from the <br>prosumer and is stored there until the consumer claims it. Using smart energy (electricity) meters the flow <br>of electricity can be tracked accurately in both ways, neighbors can purchase spare electricity using tokens <br>rather than paying money. As blockchain takes care of the accounting part, it records the terms of the <br>contracts, tracks how many energy credits have been sold, by whom and to whom. The micro-grid is <br>facilitated by its own smart contract and it can share a desired amount of energy to a connected energy <br>consumer. The customer is aware of how much consumption energy is available at any time in the central <br>storage. The smart contract of the micro-grid takes as input HECs (helios coin) or a bit coin and then releases <br>the energy that corresponds to the calculated amount of HECs or bit coin received by the sender in form of <br>the payment. The test is to monitor these exchanges and repay purchasers and dealers likewise. This project <br>is an effort to utilize blockchain methodology for the trade of sun-based power among members effectively, <br>without any need of third party vendors</p> 2021-07-04T00:00:00-04:00 Copyright (c) 2021 https://grrojs.clubforleaders.org/index.php/GRR/article/view/12 Weather Data Based Analysis of Existing Solar and Wind potential of Karachi, Pakistan 2021-07-04T11:52:24-04:00 Sabir Ali KALHORO Sabir13es66@gmail.com Ghous NAREJO ghousnarejo@gmail.com Tanweer HUSSAIN tanweer.hussain@faculty.muet.edu.pk <p>The solar irradiation and wind speed show random as well as periodic variations as a function of <br>variations in the weather.

Moreover, <br>it is poised to create healthy revenue and handsome economy for country as waste may serve as <br>energy, wealth and gold. We are converting our waste into wealth. By transforming it into useful <br>resource, Sindh solid waste management board (SSWMB) estimates that Karachi will generate <br>16,000 tons of garbage daily by 2020. Currently, Karachi metropolis produces approximately <br>12,000 tons of garbage every day. Through proper management of the solid waste, the existing huge <br>garbage may well be converted into an efficient source of income as well as energy generation. <br>By doing so, Karachi may be relatively safe, disease free and environmentally clean city. Solid <br>waste management in metropolis has emerged as a 21st century challenge. The Solid waste is <br>increasing problem day by day. It is creating environmental hazards and social problems due to <br>increase in waste, health Issues and lack of management. So it is high time to convert this <br>problem in to a viable mechanism coupled with the solution by applying the instruments of proper <br>management for the solid waste. The Solid waste ejection is the most common problem in third <br>world countries.&nbsp;</p> 2021-07-04T00:00:00-04:00 Copyright (c) 2021
