Work-related stress is one of the major risks to health and safety are involved constant changes in regulations and the accelerated pace demanded by the different activities that relate to massive groups of people being the case of institutions of higher education you can create stress factors affecting the responsiveness and the working environment of employees. It is important to analyze its impact on the work environment and investing in stress prevention to ensure labor skills. Its main objective is to design a plan for prevention and stress management to improve the working environment of employees from the maintenance of the Faculty of Administrative Sciences.

The present work deals with the topic: "The principle of gender equality and its guarantee in the right to work." The work deals with the principle of equality, which consists of the equality of rights and opportunities for all human beings, it will include equality to work, which allows any person - without prejudice to their gender, ethnicity, socio-economic situation, etc. - access a job and be treated as equal.However, from the constant efforts of the legislation to guarantee equality at work and thus avoid discrimination, in practice there are cases of study that would be thought impossible, such as the one analyzed, which is about a worker who is fired of the fire department for being a woman, since at the discretion of the government entity, with the dismissal, she is protected from carrying out an activity intended only for men. It will be studied in the same way, the measures of integral reparation that the Constitutional Court of Ecuador, dictated against this violation of constitutional rights. The methodology to be used in the research is deductive, exploratory and descriptive. A qualitative approach will be used, as it is the one of the social sciences and more punctually of the Law.

The main goal of this job is to make a doctrinal, legal and critical analysis regarding to cassation resources into justice administration operability, according to current ecuadorian regulations that are consagrated into the "Código Orgánico General de Procesos" (General Organic Code of Processes), since this legal instrument includes several formal requirements that cause cassation resource to be denied due to lack of complience of certain formalities, resulting inaccepatable the lack of justice due to this issue that being opposed to the end section of the article 169, of the Judicial Function procedural system principals declaration, included into the Republic Constitution first section: “Justice wont be sacrified due to the lonly formalities omition The primary axis of this research task will be to evidence the above argument, turning into the main point of analisys, the Constitution normative condition and its justice administration effectiveness, as well as the static and irreverent that lower hierarchy regulations could be, instead of being in harmony with the Magna Carta of the State, contributing at the same time, to the legal security principles.

Within the present work we will have to deal with: "The constitutional action to protect the right to social security." Due to the fact that social security is guaranteed in Ecuador, in practice there are problems in its exercise, as it is the case of intentionally reducing the payment corresponding to retirement, with the clear intention of avoiding employer responsibility. Another Ecuadorian experience that should be mentioned is that the social security institutions are reluctant to provide the hospital service that is owed by law to the family of the insured. In the face of these events, it has been necessary for the Constitutional Court to issue sentences compelling compliance with social security, so this work will refer to the experience that exists on this matter. The methodology to be used in the research is deductive, exploratory and descriptive. A qualitative approach will be used, as it is the one of the social sciences and more punctually of the Law.

Maize is grown throughout Brazil and used for feeding humans and animals and as a raw material for biofuels and industry. Its yield is impaired by of soil and water degradation, such as salinization, which is more serious in semi-arid regions. Three experiments were carried out in different soils (Acrisol, Cambisol, and Fluvisol) of the state of Rio Grande do Norte with the objective of evaluating biochar effect on dry mass and nutrient content of maize plants irrigated with saline water. The treatments were applied in PVC columns in a greenhouse at the Federal Rural Semiarid University, in Mossoró, according to a completely randomized design in a factorial scheme with four replications. The factors studied were biochar doses (0, 0.5, 1.0, and 1.5%) and irrigation water salinity levels (0.57, 2.65, and 4.5 dS m-1). Biochar was obtained from the carbonization of Prosopis juliflora (Sw.). At 40 days after emergence, the shoot dry mass and the plant contents of N, P, K, Ca and Mg were determined. Data were submitted to analysis of variance and regression analysis. Responses of shoot dry mass and maize nutrient contents indicate that biochar can mitigate irrigation water salinity, depending on the dose applied and the soil type.

The speciesspecies Handroanthus impetiginosus (Mart. ex DC.) Mattos, commonly known as purple ipe, belongs to the Bignoniaceae family. Could be used in recovery of degraded areas, landscaping or in permanent preservation areas, although there is a little amount of information about this species. Our goal in this project was to assess the seeds physiology by imbibition tests and considering germination of purple ipe seeds in different substrates and light restriction levels. For the imbibition test, seeds were immersed in distilled water and placed in two different temperatures (25 and 30 ºC) in a proportion of 100 seeds for 200 ml of distilled water. Checkpoints were set at 2, 4, 16, 24 and 48h. Light restriction tests involved 3 substrates: S1 (Soil), S2 (Sand + coconut fiber), S3 (Sand + Goat Manure) and three light conditions: 0%, 50% e 80%. During 75 days the following variables were considered: height, root collar diameter and leaf number. There were no differences observed between temperatures for the imbibition test and after 48h of imbibition almost became stable for both temperatures. Considering the light restriction test, we can deduce that the seedlings growth rate were affected by the substrates as well for the light conditions. S3 substrate with 50% of shadowing combination provided best outcome results.

The sustainability of irrigated agricultural systems in semiarid region is based on the maintenance of its production capacity. The objective of this work was to evaluate soil quality in agroecological and conventional irrigated areas, located in the community of Sombras Grandes, Caraúbas, Rio Grande do Norte. Simple soil samples were collected (at 0-20 cm and 20-40 cm depths) from 2009 to 2012. The quality indicators used were: physical: Bulk density (Bd), Total Porosity (TP), Penetration Resistance (PR), relation of available water soil and total porosity (AWS/TP), relation of MR/TP, Flocculation Degree (FD) and Clay dispersed in water (CDW); chemicals: Hidrogen potential (pH), Phosphorus (P), Cation Exchange Capacity (CEC), Bases Saturation (V), Base Sum (BS), Total Organic Carbon (TOC), Carbon Stock (CS), Calcium (Ca+2), Magnesium (Mg+2), Potassium (K+), Sodium (Na+), Exchangeable Sodium Percentage (ESP) and Electric Condutivity (EC). The nonparametric Kruskal Wallis, Pearson's correlation and principal component analysis were used to evaluate soil quality. BS showed significant positive difference in agroecological area with V, TOC and CEC and in conventional area with V and CEC. The Bd, TP, CDW and FD, TOC and Al+H differed significantly and the best soil quality results were found in the agroecological area (0-20 cm). Ca+2, Mg+2, K+, CEC, P and BS were not different and the high values recorded maintained soil fertility in both areas studied. The soil productive capacity in area agroecological was maintained, without the need for chemical fertilizer.

The tomato (Solanum lycopersicum) is an important crop in Brazil, however, it is susceptible to different types of bacteria races. The objective was to study the genetic parameters of 43 F2:3 families of tomato in resistance to R. pseudosolanacearum and R. solanacearum. The families were obtained from the cross between the cultivars Yoshimatsu (resistant) and IPA-7 (susceptible). Two experiments were carried out in a greenhouse at Universidade Federal Rural de Pernambuco, one for each species of the genus R. spp. A randomized block design was used with four replications and 45 treatments. There is less influence of the environment, and greater variability for R. pseudosolanacearum than for R. solanacearum, both among and within families. For R. pseudosolanacearum it is recommended to select 10 days between families, and 20 days between and within families. R. solanacearum should be selected from families only at 20 days. Larger amounts of resistant plants were identified for R. pseudosolanacearum at any time of evaluation than for R. solanacearum.

Agroforestry systems have emerged as land use alternatives, capable of reconciling agricultural and forestry production, concomitantly with the conservation of natural resources. The objective of this work was to evaluate the homegardens present in an Agro-villa in the municipality of Altamira, Pará, Brazil, concerning its composition and floristic diversity, besides the uses of plants. The data were obtained from 26 homegardens established in the Xingu Princess agrovila by means of semi-structured interviews with key informants, selected by snowball technique. In order to analyze the use and relevance of the surveyed species, the Shannon-Wiener diversity index, Pielou equitability index and importance value (IVs) were calculated. A total of 117 plant species, belonging to 52 botanical families, were identified, highlighting: Fabaceae, Arecaceae, Anacardiaceae, most of them being used in family feeding. Among the species with the highest importance value to the interviewees, orange, coconut, mango, cacao, cupuaçu, lemon and açaí were highlighted. The food and medicine categories were the most important to the interviewees, which indicated concern with food safety and health for the rural community, respectively. The Shannon-Wiener and Pielou equitability indexes indicated moderate diversity and lower individual heterogeneity, respectively, per species in the homegardens of the Xingu Princesa agrovila.

The inadequate use and management in cropping systems in the semiarid region may decline the soil's ability to sustain the production. The objective of this work was to determine the soil quality index (SQI) in agroecological and conventional irrigated agricultural experimental units (AEU), located in the community of Sombras Grandes, Caraúbas, Rio Grande do Norte. Simple soil samples (0-20cm) were collected from 2009 to 2012. To determine the SQI, it was used 11 quality indicators associated to the soil functions in maintain the productivity capacity over time: bulk density (Bd), total porosity (TP), penetration resistance (PR), water availability in soil (AWS/TP), moisture retention at -33 kPa (MR/TP), pH, phosphorus assimilable (P), cation exchange capacity (CEC), base saturation (V), soil organic matter (SOM), clay dispersed in water (CDW) and flocculation degree (FD). The SQI in agroecological and conventional irrigated AEU were classified as good (0.80) and bad (0.45), respectively. In conventional AEU there is need for agricultural practices, like injection of organic waste, that improve the FD because it was the indicator that most contributed to reduce the SQI. The SQI reflected the integrated performance of the chemical and physical properties, which can be used in making decisions about the soil use and management.
