Sustainability has become a partner in matters involving civil engineering considering that the generation of construction waste produces similar amounts in Brazil to the industrial sector, where, moreover, most cannot be ruled out in any way, because they are harmful to the environment, some of which are irreparable. The emergence of techniques and ways to build sustainably has created ideas and new destinations for construction waste. Recycled concrete is one of the solutions adopted to reduce costs with new materials and appropriate treatment to waste generated by the civil council.

This article analyzes fiber optic connectorizations used in data transmission. In this analysis, optical loss measurementsismade in mechanical connectors such as Insertion Loss (IL) and Return Loss (RL) based on the certification requirements for the commercialisation of telecommunications products by the National Telecommunications Agency (ANATEL) and international standards. In addition to the fundamental theoretical argument, we performed an evaluation of field-mounted connectors from ten different manufacturers sold in Brazil.

Coming from the Latin acrumen which means sour, the word citrus was given in antiquity to trees with acid fruits.

Soil is a fundamental resource for man’s life on earth, most of the goods he needs coming directly or indirectly from the soil. This is not done without compensation in favour of the soil, which loses its productive capacity over time. Compensation is made through the provision of both mineral and organic fertilizers to the soil. A trial was conducted in Ngandajika where it was applied to the soil, two organic fertilizers, Bat-guano and Tithonia diversifolia, a mineral fertilizer, DAP for growing corn.
