Impacts of Activities in Crushing Plant on Environment and Occupational Health of Workers Involved

Abstract With the development of societies there is a growing demand for raw materials for the construction industry, among which the crushed materials existing in the various categories, as set down the specifications of the services of competent bodies. In the long term and as a result of overuse such demands lead to exhaustion of mines and environmental degradation. These materials are produced in crushing plants, which have characteristics of development of its activities, being an aggressive environment for the people involved and, likewise, to the surrounding environment, deteriorating air, water and soil. As for the workers, since the production process, may present in the medium and long term, the emergence of so-called occupational diseases or occupational diseases, these diseases that can lead people to the inability to work and even death. It should be noted that occupational diseases relating to mineral extraction are properly characterized in the literature. In Brazil there's labor and welfare legislation they impose on public and private sectors, the zeal with health workers, and the non-compliance, characterizes the disrespect for life and health of employees, liable to punishment. Likewise, today, there is a growing concern in the world, both in public and private sectors, about the legacy of extractive activities, the need to reassess the system of production and exploitation of mineral resources used to make it sustainable and ensure the existence of future generations, compared to its current unsustainable, and especially with regard to the costs involved. The aim of this study is the importance of the process of comminution in the environment and humans. It will use a literature review, theoretical and descriptive method, as well as statistics from the Ministry of Social Security in Brazil. The reduction of environmental degradation and occupational diseases of workers require more appropriate production techniques as well as major prevention strategies. To do so, you should seek the development of new demands in the area of construction compatible with the reduced use of mineral inputs and labor.

Feeling the future: A meta-analysis of 90 experiments on the anomalous anticipation of random future events

In 2011, one of the authors (DJB) published a report of nine experiments in the Journal of Personality and Social Psychology purporting to demonstrate that an individual\u2019s cognitive and affective responses can be influenced by randomly selected stimulus events that do not occur until after his or her responses have already been made and recorded, a generalized variant of the phenomenon traditionally denoted by the term precognition. To encourage replications, all materials needed to conduct them were made available on request. We here report a meta-analysis of 90 experiments from 33 laboratories in 14 countries which yielded an overall effect greater than 6 sigma, z = 6.40, p = 1.2 7 10 with an effect size (Hedges\u2019 g) of 0.09. A Bayesian analysis yielded a Bayes Factor of 5.1 7 10 , greatly exceeding the criterion value of 100 for \u201cdecisive evidence\u201d in support of the experimental hypothesis. When DJB\u2019s original experiments are excluded, the combined effect size for replications by independent investigators is 0.06, z = 4.16, p = 1.1 7 10 , and the BF value is 3,853, again exceeding the criterion for \u201cdecisive evidence.\u201d The number of potentially unretrieved experiments required to reduce the overall effect size of the complete database to a trivial value of 0.01 is 544, and seven of eight additional statistical tests support the conclusion that the database is not significantly compromised by either selection bias or by intense \u201cp -hacking\u201d\u2014the selective suppression of findings or analyses that failed to yield statistical significance. P-curve analysis, a recently introduced statistical technique, estimates the true effect size of the experiments to be 0.20 for the complete database and 0.24 for the independent replications, virtually identical to the effect size of DJB\u2019s original experiments (0.22) and the closely related \u201cpresentiment\u201d experiments (0.21). We discuss the controversial status of precognition and other anomalous effects collectively known as psi

PUBLIC FINANCING OF HEALTHCARE SERVICES

Healthcare in Poland is mainly financed by public sector entities, among them the National Health Fund (NFZ), state budget and local government budgets. The task of the National Health Fund, as the main payer in the system, is chiefly currently financing the services. The state budget plays a complementary role in the system, and finances selected groups of services, health insurance premiums and investments in healthcare infrastructure. The basic role of the local governments is to ensure access to the services, mostly by performing ownership functions towards healthcare institutions

Enxerto ósseo tipo autógeno em maxilares atróficos

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Saúde. Odontologia.Rebordos alveolares severamente reabsorvidos nos maxilares atróficos tem sido um problema na reabilitação protética dos pacientes, tanto para colocação de implantes osteointegráveis, quanto para reabilitação com próteses removíveis. Nos casos de rebordos reabsorvidos, é necessário que se tenha uma quantidade óssea mínima, quando isso não ocorre, o enxerto ósseo autógeno é a primeira opção de escolha. Sua capacidade osteogênica, osteoindutora e osteocondutora, torna o enxerto ósseo autógeno padrão ouro nas reconstruções maxilomandibulares. As áreas doadoras intrabucais oferecem opção segura para devolver o volume ósseo em reabilitações de menor porte, no entanto quando maiores volumes ósseos forem necessários podemos utilizar áreas doadoras extra bucais Devido a sua microarquitetura, o enxerto autógeno tem baixo potencial de reabsorção, sendo considerado uma opção de tratamento previsível e com mínimas complicações quando realizado de maneira correta.Atrophic alveolar ridges severely absorbed in jaws has been a problem in prosthetic rehabilitation of patients, both for placement of osseointegrated implants, and for rehabilitation with removable dentures. When it is chosen by the placement of dental implants, care recipient area and the correct selection of attachment to be used should be analyzed. It is essential in these cases that have a minimum bone quantity necessary for osseointegration to occur. When this does not occur, the autogenous bone graft is the first option of choice. Their osteogenic and osteoinductive properties and osteoconductive, makes the gold standard autogenous bone graft in maxillomandibular reconstruction. The intraoral donor sites offer safe option to return the bone volume in rehabilitation smaller, however when larger bone volumes are required we can use extra oral donor sites Due to its microarchitecture, the autograft has low potential for absorption and is considered an option and predictable treatment with minimal complications when performed correctl

The actin binding proteins cortactin and HS1 are dispensable for platelet actin nodule and megakaryocyte podosome formation

A dynamic, properly organised actin cytoskeleton is critical for the production and haemostatic function of platelets. The Wiskott Aldrich Syndrome protein (WASp) and Actin-Related Proteins 2 & 3 Complex (Arp2/3 complex) are critical mediators of actin polymerisation and organisation in many cell types. In platelets and megakaryocytes, these proteins have been shown to be important for proper platelet production and function. The cortactin family of proteins (Cttn & HS1) are known to regulate WASp-Arp2/3-mediated actin polymerisation in other cell types and so here we address the role of these proteins in platelets using knockout mouse models. We generated mice lacking Cttn and HS1 in the megakaryocyte/platelet lineage. These mice had normal platelet production, with platelet number, size and surface receptor profile comparable to controls. Platelet function was also unaffected by loss of Cttn/HS1 with no differences observed in a range of platelet function assays including aggregation, secretion, spreading, clot retraction or tyrosine phosphorylation. No effect on tail bleeding time or in thrombosis models was observed. In addition, platelet actin nodules, and megakaryocyte podosomes, actin-based structures known to be dependent on WASp and the Arp2/3 complex, formed normally. We conclude that despite the importance of WASp and the Arp2/3 complex in regulating F-actin dynamics in many cells types, the role of cortactin in their regulation appears to be fulfilled by other proteins in platelets

First reports of computed tomographic colonography for the screening of colorectal polyps in acromegalic patients

*Aim:* To analyze the CTC performance for the screening of colorectal polyps in acromegalic patients. 

*Materials and Methods:* A prospective study of 21 acromegalic patients, 12 male and 9 female, average age 49, who underwent CTC and CC. CTC was performed with a GE Helical Multislice Computed Tomography Apparatus. The colonoscopy was performed, in the same day, without previous knowledge of the CTC diagnostics. The study evaluated the capacity of CTC to detect patients with colorectal polyps and identify each colorectal lesion described by CC. 

*Results:* In two patients (2/21), CC was incomplete. However, in all patients CTC was complete. In Phase I (“Per Patient”), CTC diagnosed 8 of the 9 patients with colorectal polyps and showed 88% sensitivity, 75% specificity and 81% accuracy. In Phase II (“Per Polyp”), out of the 21 acromegalic patients included in this study, 12 presented normal findings at CC. A total of 19 polyps were identified in 9 patients. 10 of the 19 polyps were smaller than 10 mm, and 9 were equal to or larger than 10. CTC identified 7 of the 9 polyps ≥ 10 mm described by CC and only 6 of the 10 small polyps identified at CC were detected by CTC. The histological analysis of resected lesions revealed 12 tubular adenomas, 6 hyperplastic polyps and 1 colonic tubulo-villous adenoma with an adenocarcinoma focus. 

*Conclusion:* In this study, CTC was performed without complications and a complete and safe colorectal evaluation was possible in all acromegalic patients. Moreover, CTC showed good sensitivity to identify acromegalic patients with colorectal polyps
