Some components found in the composition of the tannery sludge are nutrients for the plants; it can be considered an alternative source of fertilization as they have favorable agronomic ...characteristics. However, it is reported in some studies that the presence of chromium and sodium in this residue causes physiological and anatomical disturbances that inhibit the development of the plants. The objective of this study was to evaluate the influence of chromium and sodium on the physiology, anatomy, and development of Conilon coffee seedlings grown on substrates produced with tannery sludge and equivalent doses of chromium and sodium. The experiment was carried out in nursery using randomized block design, containing 5 treatments and 7 repetitions. The treatments consisted of the application of a 40% tannery sludge dose and equivalent doses of chromium and sodium mixed with a conventional substrate. Notably, the presence of sodium in the substrate caused greater damage to the plants, negatively influencing the physiology, anatomy, and, consequently, development of the plants, while the presence of chromium suggests that it does not influence much the evaluated characteristics. The treatment with tannery sludge, on the other hand, despite containing the same chromium and sodium contents, revealed a more pronounced negative influence on the physiology, anatomy, and development patterns of the seedlings. This shows that sodium and chromium alone are not the only factors responsible for the lowest growth indicators studied.
Waste from leather processing, called tannery sludge, has been the focus of many studies into its use in agriculture because its composition is rich in nitrogen and organic matter and has high soil ...reducing power, giving it great potential for agricultural use (Sales et al., 2017; Berilli et al., 2018; Berilli et al., 2020). ...in order to make use of tannery sludge as an alternative source of fertilization for plants, other components that act in the stabilization, structuring and complexation of chromium need to be added to seedling substrate. ...the present study aimed to evaluate whether the association of humus and tannery sludge in the substrate is beneficial for the cultivation of conilon coffee seedlings. ...due to the complexity involving humus ionization potential and chromium valence instability, some questions were raised: (1) Does humus really have the capacity to make chromium in tannery sludge unavailable? (2) Does the use of humus in association with tannery sludge positively affect the development of conilon coffee seedlings compared to conventional substrate? (3) If humus does make chromium unavailable, will the plants show signs of oxidative stress induced by chromium? MATERIAL AND METHODS Experiment implantation This study was conducted at the Federal Institute of Education, Science and Technology of Espirito Santo - Itapina campus, located in the municipality of Colatina, northwestern Espirito Santo State, within the geographic coordinates 19° 32'22" south latitude; 40° 37'50" west longitude and altitude of 71 meters.
In vegetable production, seedling propagation is one of the most important steps as it directly influences the final performance of the plants. In order for such condition, the propagation substrate ...must be in good condition. The objective of this work was to evaluate the effect of different combinations of tannery sludge and urban waste compost as substrates in comparison to the commercial substrate Maxfértil

on the growth and quality of eggplant seedlings. The experiment was conducted in a greenhouse using a randomized block design with eight treatments and six replications. The commercial substrate was Maxfértil

, a crushed pine bark, with limestone, and seven treatments with increasing proportions of tannery sludge/decreasing urban waste compost (0/100; 10/90; 30/70; 50/50; 70/30; 90/10 and 100/0 v/v). Characteristics of emergence, growth, quality and leaf nitrogen (N) content were evaluated. No difference was found in the emergence of eggplant seedlings among the different treatments used; however, the growth characteristics, quality and N content featured significant effects when the seeds were propagated in alternative substrates. Regression adjustments pointed to an optimal range of 41-49% of tannery sludge associated with urban waste compost for the evaluated characteristics. The strong correlation between SPAD and N content shows its potentiality in detecting N deficiencies in seedlings. The use of tannery sludge residues associated with urban waste compost seems to be an appropriate and sustainable practice for recycling with high agronomic potential.
Objetivou investigar a estrutura administrativa e o perfil dos gestores das AAAs ligadas a Universidade Federal de Mato Grosso do Sul/Cidade Universitária. Para tanto, investigou-se presidentes e ...membros das diretorias das AAAs vinculados a Universidade Federal de Mato Grosso do Sul, com aplicação de questionários eletrônicos. As AAAs encontram-se formadas predominantemente por cursos, compostas pelo mínimo oito e máximo 39 diretorias, com presidência, vice-presidência e secretaria (gestão central) e diretoria de esportes, marketing, eventos e tesouraria (gestão setorial) predominando. A filiação tem a matrícula no curso e pagamento da anuidade como principais exigências, não se relaciona ao número de discentes, sendo os descontos em produtos, instituições parceiras e eventos os principais benefícios. A presidência é majoritariamente masculina, enquanto as diretorias, homogênea, matriculados entre o 5º e 8º semestre, participantes da Educação Física e treinamentos esportivos na Educação Básica. A falta de tempo e falta de oportunidades foram as principais barreiras para quem não teve experiência esportiva.
Abstract: It aimed to investigate the administrative structure and the profile of AAAs managers linked to the Federal University of Mato Grosso do Sul/Cidade Universitária. For that, presidents and members of the boards of the AAAs linked to the Federal University of Mato Grosso do Sul were investigated, with the application of electronic questionnaires. The AAAs are predominantly formed by courses, with a minimum of eight and a maximum of 39 directorates, with the presidency, vice presidency and secretariat (central management) and sports, marketing, events and treasury (sectoral management) predominating. Membership has enrollment in the course and payment of the annual fee as its main requirements, it is not related to the number of students, with discounts on products, partner institutions and events being the main benefits. The presidency is mostly male, while the directors, homogeneous, enrolled between the 5th and 8th semester, participants of Physical Education and sports training in Basic Education. Lack of time and lack of opportunities were the main barriers for those who had no sporting experience.

•Health care-associated infections are an important public health and patient safety issue.•A bundle is a specific tool with clear parameters to guide the multidisciplinary team in the intensive care ...unit.•Central line-associated blood stream infection, catheter-associated urinary tract infection, and ventilator-associated pneumonia rates declined 58.6%, 56.7%, and 82.6%, respectively, after bundle implementation.
A retrospective cohort study was conducted to evaluate the bundle of techniques developed by the multidisciplinary team to minimize infections in an adult intensive care unit over a 22-year span. Two periods were analyzed: 1996-2006 and 2007-2017. Bloodstream infections, urinary tract infections, and ventilator-associated pneumonia declined 58.6%, 56.7%, and 82.6%, respectively (P < .05) from 2007 to 2017 compared with these same infections during 1996-2006.
