Interplay between structure and density anomaly for an isotropic core-softened ramp-like potential

Using molecular dynamics simulations and integral equations we investigate the structure, the thermodynamics and the dynamics of a system of particles interacting through a continuous core- softened ramp-like interparticle potential. We found density, dynamic and structural anomalies similar to that found in water. Analysis of the radial distribution function for several temperatures at fixed densities show a pattern that may be related to the origin of density anomaly.Comment: 7 pages, 3 figure

Business plan for social impact: mobile application to address size discrimination

Size discrimination, also called sizeism, is a type of discrimination based on people’s weight or height and often appears unnoticed in everyday life. The main purpose of this work is to present a business plan for a mobile application that aims to help address size discrimination, contributing to the social inclusion of those who have experienced it. This mobile application will allow personal experiences and unheard voices to be public and shared without temporal and spatial barriers. Furthermore, it gives an opportunity for professionals to learn and change their attitudes toward size discrimination by connecting with people’s experiences. In order to better understand the impact of this project on society, it was made a research about weight and height discrimination, as both are included in size discrimination, its roots and major issues. Moreover, it was conducted a survey in which was obtained significant results for this project. Additionally, strategic analysis tools such as PEST Analysis, Five Porter’s Forces and SWOT Analysis, were used in order to review this project’s market and competitive context. The following steps were to develop the segmentation, target and positioning as well as the marketing mix of this project. Lastly, there are many private programs and government programs that support social causes and social entrepreneurship. Therefore, this business intends to request funds from them, with the purpose of that, a financial analysis was developed to find out how much would be requested.A discriminação por tamanho, também chamada de tamanhismo, é um tipo de discriminação com base no peso ou altura das pessoas e que muitas vezes passa despercebida na vida cotidiana.

Thermodynamic, Dynamic and Structural Anomalies for Shoulder-like potentials

Using molecular dynamic simulations we study a family of continuous core-softened potentials consisting of a hard core, a shoulder at closest distances and an attractive well at further distance. The repulsive shoulder and the well distances represent two length scales. We show that if the first scale, the shoulder, is repulsive or has a small well, the potential has a region in the pressure-temperature phase diagram with density, diffusion and structural anomalies. However, if the closest scale becomes a deep attractive well the regions in the pressure-temperature phase diagram where the three anomalies are present shrink and disappear. This result enables us to predict by the shape of the core-softened potential if anomalies would or would not be present

Structural anomalies for a three dimensional isotropic core-softened potential

Using molecular dynamics simulations we investigate the structure of a system of particles interacting through a continuous core-softened interparticle potential. We found for the translational order parameter, t, a local maximum at a density $\rho_{t-max}$ and a local minimum at $\rho_{t-min} > \rho_{t-max}$. Between $\rho_{t-max}$ and $\rho_{t-min}$, the $t$ parameter anomalously decreases upon pressure. For the orientational order parameter, $Q_6$, was observed a maximum at a density $\rho_{t-max}< \rho_{Qmax} < \rho_{t-min}$. For densities between $\rho_{Qmax}$ and $\rho_{t-min}$, both the translational (t) and orientational ($Q_6$) order parameters have anomalous behavior. We know that this system also exhibits density and diffusion anomaly. We found that the region in the pressure-temperature phase-diagram of the structural anomaly englobes the region of the diffusion anomaly that is larger than the region limited by the temperature of maximum density. This cascade of anomalies (structural, dynamic and thermodynamic) for our model has the same hierarchy of that one observed for the SPC/E water.Comment: 19 pages, 8 figure

Quality management and sustainability in logistics service providers: case study in brazilian company

Logistics operators have become important agents in supply chains, due to the current trend of outsourcing logistical activities by companies. In this way, the level of quality of the services provided is an important aspect for the competitiveness of companies. In addition, the sustainability aspect has become relevant, given the environmental impact caused by logistics activities. Studies have shown that there are points of convergence between quality management approaches and sustainable practices. The objective of this work was to analyze aspects of quality management and sustainability in Brazilian logistics operators, from the perspective of the company contracting these services. To this end, a case study was conducted at a large company that outsources its logistics activities. The five main logistics operators providing services to the company were considered. The analysis was carried out on the basis of a model that integrates sustainability and quality management criteria. Quality assets, processes and dimensions were considered.&nbsp; It was found that the contracted logistics operators have a wide portfolio of services offered, quality assets and well-defined processes. However, sustainability practices are still in their infancy

Water diffusion in rough carbon nanotubes

We use molecular dynamics simulations to study the diffusion of water inside deformed carbon nanotubes with different degrees of deformation at 300 K. We found that the number of hydrogen bonds that water forms depends on nanotube topology, leading to enhancement or suppression of water diffusion. The simulation results reveal that more realistic nanotubes should be considered to understand the confined water diffusion behavior, at least for the narrowest nanotubes, when the interaction between water molecules and carbon atoms is relevant.Comment: 17 pages, 8 figure

Ocorrências de trânsito com motocicleta e sua relação com a mortalidade

This study characterizes traffic accidents involving motorcycles according to local conditions, data concerning the type of accident, date and time, and identifies among these variables those associated with the death of victims. This retrospective study uses data from traffic collision reports from 2004 and death records from the institute of forensic medicine. A total of 99.4% of the events occurred in urban areas, where illumination (87.4%), weather conditions (80.6%); and traffic signs (70.6%) were satisfactory. Collisions between motorcycles and cars or pickup trucks prevailed (55.5%), followed by motorcycle falls (18.0%). In relation to the type of collision, the highest percentage was observed in broadside collision category (35.2%). There were differences between the groups of fatalities and survivors in relation to the area and illumination in the collisions site, in addition to the types of collision and impact. The conclusion is that local conditions and types of collision and impact stand out among the multiple variables defining the severity of accidents involving motorcycles.Se tuvo por objetivo caracterizar las ocurrencias de tránsito con motocicleta, según condiciones locales, datos relacionados al tipo de accidente, fecha y hora, además de identificar entre esas variables las que se asociaron con la muerte de las víctimas.

Evaluation of sexual behavior and reproductive cycle of bitches / Avaliação do comportamento sexual e ciclo reprodutivo de cadelas

The canine reproductive cycle has four distinct phases, established by hormonal changes that induce morphological, clinical and cytological changes in the vaginal tract. These stages are known as proestrus, estrus, diestrus and anestrus. The aim of this study was to obtain evaluative parameters on the sexual behavior of the female canine in each of the different stages of the estrous cycle for a quick and easy visual identification. Nine female dogs of different breeds were used: ShihTzu (1), SRD (2), Pug (2), YorkShire (2), Pinsher (1) and Fila Brasileiro (1), with ages varying from one to five years and weight between 5kg and 40kg. Samples of vaginal mucus were collected from each animal, using a swab for cytological analysis, to classify the phase of the cycle and associate it with the sexual behavior presented by the animal. The results of the research elucidated that the canine females had different habits in correlation with the stages of the estrous cycle, the coexistence or not with other animals proved to be quite influential in this aspect, as well as the contact and training by the tutors. Possible patterns of behavior associated with the estrous cycle in dogs were obtained, as well as individualities in the animals studied, which can be explained when we relate the behavior to the understanding of the endocrine pattern and its interrelations.
