Centro de Integração da Cidadania (CIC): uma experiência inovadora de acesso à Justiça e educação em direitos humanos

O objetivo com este artigo é apresentar o programa Centro de Integração da Cidadania (CIC), da Secretaria de Justiça e Defesa da Cidadania do Estado de São Paulo, como uma nova esfera da justiça. Isso significa dizer que o CIC – diversamente das esferas tradicionais de justiça – não objetiva apenas e tão somente decidir conflitos. Para além dessa tarefa tradicional, o programa apresenta um objetivo amplo e multidimensional cuja meta central é a educação em direitos humanos

L’enfant sujet des droits de l’homme : réflexions en Droit français et en Droit brésilien

Le XXe siècle a vu l’émergence des droits de l’enfant. Sous l’impulsion de la Convention internationale des droits de l’enfant dont on célèbre le trentième anniversaire cette année, les enfants sont désormais universellement sujets de droit et bénéficient des droits de l’homme. La France et le Brésil reconnaissent à leurs enfants une multitude de droits personnels. Si au XXIe siècle, le droit positif permet une meilleure protection des mineurs, il n’en reste pas moins perfectible afin de consacrer une reconnaissance de l’enfant comme sujet de droit de manière plus aboutie, comme le démontre les réflexions résultant d’une comparaison des droits français et brésilien.

This work consists in the development of a system for data acquisition of parameters in an agricultural application. For this, the system includes the monitoring of soil moisture and atmospheric sensors (temperature and relative humidity), in order to provide subsidies to farmers in decision-making, aiming at a future implementation of an automated irrigation system, with minimization of waste of water resources. Data acquisition is carried out by means of sensors connected to a microcontrolled system, and the signals are transmitted through a radio frequency module using LoRaWanTM protocol. Data is received at a gateway and made available in the cloud, applying Internet of Things (IoT) concepts, and can be monitored in real time in an academic interface. Additionally, the data can also be monitored through a simplified interface accessible through an app developed specifically for the application

ANÁLISE E APLICAÇÃO DE ESTRUTURAS DE SUFIXOS NA RESOLUÇÃO DO STRING MATCHING

String Matching é o problema que busca responder a seguinte pergunta: “É possível encontrar determinado padrão dentro de um texto?”. É um problema amplamente estudado na Ciência da Computação e também na Biologia Computacional, devido à existência de suas diferentes modificações em ferramentas de pesquisa e também no processamento de cadeias de DNA. Já existem algoritmos que alcançaram a solução ótima para responder a pergunta do problema, entretanto tais soluções não possuem a mesma eficiência nas extensões e variações do problema. Dessa forma, diversas pesquisas tem estudado estruturas de dados relativas aos sufixos do texto para alcançar soluções que sejam capazes de resolver variações complexas do string matching. O presente trabalho realiza um estudo e análise aprofundada sobre a eficiência de dessas estruturas: a árvore de sufixos e o autômato de sufixos. Algoritmos clássicos também são abordados e comparados às estruturas enquanto o trabalho é discorrido. As análises seguem critérios estatísticos, tempos de execução e complexidade de algoritmos para obter maior grau de confiança nos resultados

Growth and genetic parameters of progenies of Cordia trichotoma in the juvenile phase

Increasing the productive potential of native species is a challenge for forest genetic improvement. Progeny tests are efficient tools to determine the reproductive capacity of individuals and to assist with the selection of superior genotypes. Cordia trichotoma (Vell.) Arrab. ex Steud, is a native species of commercial interest due to its high potential for sawn wood. The performance of seedling production from different progenies was the objective of this work. Seeds were collected from 34 matrices selected phenotypically and georeferenced in the region of Lavras - MG. The experiment was conducted in a completely randomized design with 4 replications of 12 plants. Germination after 70 days of sowing, survival and height at 170 days after germination were evaluated. Height and genetic parameters were estimated according to mixed REML / BLUP models using the Selegen software model 82. Progeny 104 (70.8%) was superior in germination and progenies 86 (35.42%), 92 (35.42%) and 111 (43.75%) had the highest survival rates. Height shows high values for the individual additive genetic variation coefficient (49.18%) and genotypic variation coefficient between progenies (24.59%) and moderate values of heritability in the restricted individual sense (0.45) and heritability within progenies (0.38). Due to high values for the coefficient of genotypic variation and moderate values of heritability, there is a potential for height improvements. Progenies 104 stand out in the germination and the progenies 86, 92 and 111 in the seedlings survival). Regarding height, progeny 95 is the only one that stands out negatively

Low Density Lipoproteins at 2% Concentration Can Replace Whole Egg Yolk in TES-Tris-Milk Extender for Freezing Buffalo Sperm Cells

Background: Over the years, the most commonly used extenders for semen cryopreservation contain egg yolk as cryoprotectant. However, more recent studies have used the low density lipoproteins, extract of hen egg yolk which is responsible for the cryoprotective effect. Nevertheless, little was known about its required minimum concentration as well as its interaction with other extra cellular cryoprotectants, like skimmed milk. The present study aimed at investigating the effect of replacing whole egg yolk by adding low density lipoproteins at low concentrations, in TES-Tris-skim milk based extender, on the post-thaw quality of buffalo bull sperm.Materials, Methods & Results: Eighteen ejaculates were collected from six buffalo bulls and diluted with TES-Tris-skim milk based extender containing LDL, extracted from hen egg yolks, at the concentrations of 2%, 4%, 8% and 14%, against a control extender containing 20% fresh egg yolk. After semen collection, analyses of subjective motility, vigor, force tourbillon, sperm concentration (Neubauer chamber) and sperm morphology (phase contrast microscopy) were performed. The diluted semen was packaged in 0.25 mL straws, and cooling was performed on computerized machine (TK 4000®), using a cooling rate of -0.25°C/min to 5°C. Semen was kept in balance at 5°C for 4 h. The straws were frozen in an ice chest, kept at 5 cm from the surface of liquid nitrogen for 20 min and then immersed in liquid nitrogen. The samples were kept in cryogenic container until thawing. Post-thaw kinetic parameters during incubation at 37°C (CASA), sperm membrane integrity (SYBR-14/PI), membrane functionality (hypo-osmotic swelling test) and DNA fragmentation (%DFI - SCSA) were evaluated after thawing. Immediately post-thaw, total motility was higher in the control (56.53 ± 9.73) than in the tested extenders; however, after 30 min the difference was no longer detected. All other kinetic parameters presented significantly better results in extenders containing 2%, 4% and 8% LDL, compared with the control. There was no difference between treatments regarding the integrity of membranes or fragmentation of the DNA after freezing/thawing procedures.Discussion: The molecules of low density lipoproteins of egg yolk have the known action of sequestering BSP ( binder of sperm proteins) protein, due to the chemical affinity of their main components, phosphatidylcholine and phosphatidylethanolamine. The BSP are responsible for removing cholesterol from the plasma membrane of the sperm, preparing it for the sperm capacitation phase. Low density lipoproteins by inhibiting the action of the BSP increase the stability of the plasma membrane during the freeze-thaw process. The milk caseins micelles have a similar ability to bind the BSP, but with lower affinity. The present study has shown that the use of purified low density lipoproteins has an advantage over the use of whole egg yolk, especially with regard to the kinetic parameters of the spermatozoa after thawing. Furthermore, it was observed that low concentrations of low density lipoproteins, such as 2%, in extenders containing skim milk, could preserve the sperm cell during the freeze-thawing process like that higher LDL concentrations and whole egg yolk. Further studies are needed to determine if the cryoprotectant action found in this study was a result of the synergistic action of skim milk with lipoproteins or even at low concentrations like 2% the lipoproteins can provide protection to the buffalo spermatozoa during freezing, as it has been reproduced in other domestic species. In conclusion, our results indicated that the extender TES-Tris-skim milk containing 2% LDL extracted from egg yolk could be used successfully in the cryopreservation of buffalo sperm cells

MARKET AND PRODUCTION OF AGROECOLOGICAL SEEDS

In recent decades, agriculture has been changing mainly in terms of organic production, consumption and market. This increase is due to people's interest in pesticide-free products that meet all environmental, cultural and social issues, presenting itself as a highly competitive and lucrative market niche. For this reason, this bibliographic review aims to describe the market scenario and the production of agroecological seeds, in addition to characterizing the production of organic seeds and evaluating the potential of this market niche, which is increasingly the target of investments and demand for food. , but it is important to have more studies about it, as well as specific legislation for organic seeds
