Abstract

The following article presents a prototype for an electrical claw system attachable to Canadian canes. This project occurs at the Fundação Escola Técnica Liberato Salzano Vieira da Cunha in Novo Hamburgo with the intent of figuring out if there was a way of developing a device attachable to Canadian canes to help users with motor deficiency on the leg retrieve belonging on the floor. The knowledge necessary for this project was based on mechanical engineering knowledge of pulleys and electronic knowledge of motors and the prototyping platform Arduino. The research had two phases: the software prototyping and planning and the construction of the prototype. We were able to conclude the prototype, although there remains a big space for improvement soon.

Research Inventy: International Journal of Engineering & Science , Volume 10 ~ Issue 7

Abstract

This paper presents a study on the development of an adhesive with specific characteristics such as: the shear strength, flexibility and the practicality of being adhered to the glove according to the need of its user. In view of this, the project has the problem of making a protective coat for gloves that is resistant to cutting, flexible, so as not to disturb the movement, and that can be applied in any region of the hand, according to the need of its user. Consequently, its objectives are: to study the materials to complete this task, as well as to validate its operation through tests and to use materials from other operations. The methodology was based on the collection of waste from the grinding operation and, at first, its pressing with a plastic bag. As this operation failed, it was attempted to dissolve the bag and separately impregnate the iron powder and the residue in that solution to obtain a homogeneous film, thereby making it one of the layers of the adhesive. The results obtained in the first test were unsatisfactory because the pressed layers did not unite and the second test is being performed; therefore, the study is not yet complete.

Keywords: Adhesive, Cut resistance, Grinding powder.

Research Inventy: International Journal of Engineering & Science , Volume 10 ~ Issue 7

Abstract

This paper's objective is to develop a cap for the quantity of toothpaste for expelling the index of 0.07 milligrams of fluoride ions for each milligram of its body mass per day for children under seven years. The rationale is that children younger than seven years should not regularly ingest excess fluoride because, above the indicated index, they are at serious risk of developing dental fluorosis. Being a pathology in which it arises only in childhood, more specifically in the formation of the dental germ, causing a problem for the rest of the life if not treated-causing small white patches (in the lightest cases) or brownish spots (in the most severe cases). This pathology does not cause any changes in oral health but generates a shift in color, which can cause aesthetic damage. The treatment is costly, and the most common are microabrasion and whitening. From this, we intend to develop a prototype, with polypropylene, that does not have large weights and dimensions, thus offering secure handling, transportation, and use. Also, we will study the optimal issues of brushing amounts between the child's weight and the parts per million fluorides of toothpaste.

Keywords: Dental fluorosis, Fluorine, Toothpaste, Children.

Research Inventy: International Journal of Engineering & Science , Volume 10 ~ Issue 7

Abstract

Pico Hydro is a concept used for small-scale hydroplants for power generation under 5 kW. Small turbines of 200 to 300 W can supply a specific demand, such as a lamp, circuit, sensor, and others aplications. Pico Hydro generally occur in the flow, without the presence of a reservoir. Pipes divert the flow directly to a small turbine before being exhausted. This paper is the projection of a system to capture rainwater for the generation of electric power in small devices, consumable questioning – if your income. It is a system of great importance, as well as take advantage of a natural phenomenon, will be generating clean energy that can be reused on another device.

Nigeria
Research Inventy: International Journal of Engineering & Science , Volume 10 ~ Issue 7

Abstract

Mining is an important source of revenue of the economy in many developed countries. Nigeria is dependent on mineral exploitation for the diversification of her revenue from oil. Which diversification caused the mining sector to flourish. At the same time mining had serious environmental, health and social costs to the country that may increase dramatically in the next few years. The gap that must be addressed is the demand for solid minerals may lead to exploiting them without considering consequences and the absence of strict regulations to manage the sector. This paper notes that mining effects are destroying environment and threating workers health in Nigeria. Deforestation, soil erosion, water and air pollution play significant roles in the threat to the health of workers and communities in close proximity to mines............

Research Inventy: International Journal of Engineering & Science , Volume 10 ~ Issue 7

Abstract

Not all yoghurts produced and sold can be considered as probiotic yoghurts, simply because probiotic yoghurts should conform to standards in terms of the proximate, physicochemical and probiotic Lactic Acid Bacteria count. The aim of this study is to conduct comparative evaluation on the physicochemical, probiotic status and proximate composition of some commercially produced yoghurt stored under ambient condition. Five commercially sold brands of yoghurts were purchased, three (A,B,C) from large scale manufacturers, two (D, E) from small scale manufacturers, while a control sample (F) was produced in the laboratory using commercial starter cultures. Enumeration of Lactic acid bacteria (LAB) and determination of physicochemical parameters, proximate analysis and organoleptic properties of the samples was carried out in triplicate on a daily basis for six days...........
