The management of immature permanent teeth with pulpal disease can be very challenging for the clinician. Regeneration is the process of renewal, restoration, and growththat makes genomes, cells, or organisms resilient to natural fluctuations or events that cause disturbance or damage. Every species, from bacteria to humans, is capable of regeneration. Regeneration can either be complete where the new tissue is the same as the lost tissue, or incomplete where fibrosis occurs after the necrotic tissue is removed.

Participant observation can be an excellent way to gather qualitative data and observe real behaviours, provided the participant observer does not cause a behavioural change from the norm. Such a change in behaviour is known as the Hawthorne effect – where people modify their behaviour when they know they are being watched or studied. Though little research has been published on the influence of the Hawthorne effect in simulation studies, it is an inescapable phenomenon that can have a dramatic impact on research.

Objective: It investigate the perception of obstetric violence through the reports of women who had their children through vaginal delivery and cesarean section in the Regional Hospital Dr. Abelardo Santos. Method: This was a qualitative study with descriptive-exploratory characteristics. It Held in a public hospital in Belém/Pa, this study was conducted with 15 hospitalized women. The collection was carried out from March to April 2017, in which the participants were first invited to the survey, where they were informed and clarified about the research theme and its objectives.

Introduction: Head and neck cancer is the commonest malignancy in India. Most of the cases present at a locally advanced stage. Concurrent chemoradiotherapy with or without neo-adjuvant chemotherapy are both viable treatment options in locally advanced cases. Materials & Methods: 30 biopsy proven cases of locally advanced head and neck cancer attending the Out Patient Department of Radiotherapy from August 2016 to May 2018, meeting specified Inclusion and Exclusion Criteria, willing to participate in the study were included.

In order to identify the actions of health education fulfilled by nurses related to homophobic bullying, search was accomplished, the databases: MEDLINE, SCOPUS, CINAHAL, IBECS, ADOLEC, CIDSAÚDE, ERIC, APA PYSICNET, SOCINDEX, LILACS, BDENF and WEB OF SCIENCE, from the descriptors (DeCS / MeSH): Students, bullying, homophobia and nursing, in the Portuguese, Spanish and English languages, in the period of 2011-2017. The selected studies were evaluated regarding methodological approach and level of evidence.

The scientific knowledge is subjected to a process of production whose dynamics involves transformations in the understanding of the treatment of nature, which impedes from being characterized as ready, true and finished. Moreover, this is a challenge in the field of scientific education. In this sense, it is one of the functions of Science teaching to enable the student to appropriate the structure of scientific knowledge and its explanatory and transformative potential.

This paper presents the development of a pressurized ejector for particulate material handling by means of pneumatic transport, defined as a way to transport materials mainly in powder or granular form using a gas stream. Operating through high-pressure batches, the proposed equipment consists in an alternative to the conventional Pressure Vessel commonly used in pneumatic transport, having as advantages the reduction in complexity of operation; equipment dimensions; energy expenditure and production cost.

Solar technologies are continuously and rapidly growing these days. Researchers continue to look for ways to optimize the harvesting of solar energy. Application of mathematical concepts is one way of increasing the efficiency of solar panels. This study used the concept of (1) Golden ratio and Fibonacci sequence, and (2) perpendicularity angle to the sun to construct solar panels that would maximize the energy output of the panels.

The purpose of this research is to study the right of people to non-identification by anatomical sex. Identification of biological sex is an extremely common practice in society. The first legal act, after the birth with life, is the public registry and the birth certificate in which the identification of the biological sex. Gender as a historical and cultural construction should not be understood as determinant and permanent.

The path to sustainable development requires the involvement of consumers and producers of goods. Ecolabels have emerged as the primary avenue of communication between the main agents within production chains, enabling environmental impact reduction and serving as criteria for consumer choices. However, many labels are not easy to attain (mainly for small businesses), as they demand environmental and safety requirements.
