ABSTRACT. The aim of this study was to investigate the hair coat characteristics of sows raised in a free-range system in a tropical climate and assess associations with effective radiative properties and thermal conductivity. Bristles were collected from December 2017 to April 2018 and evaluated for diameter (mm), length (mm), and density (bristles per cm2). From these data, the effective thermal conductivity, absorptivity, transmissivity, and reflectivity of the hair coat were determined. Sows were separated into four groups according to skin pigmentation and color parameters. The environment was characterized with regard to average air temperature (°C), relative humidity (%), and shortwave radiation (W m-2). The data were analyzed by repeated measures analysis. Bristle length (33 mm) and density (10 bristles cm-2) were lower in summer than in colder months (48 mm and 20 bristles cm-2, respectively). Effective absorptivity was higher and transmittance was lower in more pigmented sows, demonstrating a connection with protection against solar radiation. Therefore, the combination of a pigmented and dense coat seems to be ideal for pigs reared in free-range systems.

ABSTRACT Objective To analyze the karyotype test and myeloid panel with next-generation sequencing findings in patients with myelofibrosis, and to compare transplant characteristics in patients referred for bone marrow transplantation. Methods Retrospective, single-center study with patients diagnosed with myelofibrosis treated at Hospital Israelita Albert Einstein between 2010 and 2020. Results A total of 104 patients with myelofibrosis were examined. Patients who had not been submitted to tests in our service were excluded. The final sample comprised 69 patients. Of these 69, 56 were submitted to karyotyping and 22 to myeloid panel with next-generation sequencing. Karyotype was normal in 60% of the patients and altered in 40%. The prevalence of high-risk molecular mutations was higher in patients referred for bone marrow transplantation (100% versus 50%). The median follow-up of transplant patients was 2.4 years and the overall survival at 2 years was 80% (95%CI: 62-100%). Conclusion The molecular analysis enables estimating the patient’s risk and thus instituting more aggressive treatment such as bone marrow transplant for patients at higher risk, being a relevant tool to guide therapy. Given the significance of molecular analysis for therapeutic decision-making in myelofibrosis, collection and disclosure of data on the prevalence of cytogenetic changes and findings of next-generation sequencing in affected patients is important. nextgeneration next generation Retrospective singlecenter single center 201 2020 10 examined excluded 6 5 60 40 40% highrisk high 100% 100 (100 50%. 50 50% . 50%) followup follow up 24 4 2. 80 95%CI 95CI CI 95 (95%CI 62100%. 62100 62 62-100%) patient s therapy decisionmaking decision making important 20 202 1 (10 8 9 62100% 6210 62-100% (1 621 62-100 ( 62-10 62-1 62-

ABSTRACT The objective of this study was to create a single mathematical equation able to estimate the leaf area of different cassava cultivars from one lineal dimension without destroying any plant tissue. Two hundred leaves per cultivar from ten cultivars were used to calibrate the model and more than one hundred leaves per cultivar were used to test its predictive capacity as independent data. All equations were the result of the nonlinear correlation between the leaf area and the length of its central lobe. To validate it as a “general” equation, another set of five cultivars were used. A “specific” equation for each cultivar was also calibrated to compare with the “general” equation’s performance. Cultivar Vassourinha has remarkably different leaf morphology from the other nine cultivars, making the “general” equation’s tendency line deviate and lowering its coefficient of determination. Therefore, one more equation was generated excluding that cultivar and, as a result, it was not possible to estimate the leaf area from all the cultivars using only the “general” equation. The “general without Vassourinha” equation has a high accuracy level when estimating leaf area of the other nine cultivars, plus the extra five cultivars that were included to validate the general equation; all of them present similar leaf morphology. Due to its importance, Vassourinha cultivar’s “specific” equation should be used when estimating leaf area for this cultivar or other cultivars with similar leaf morphology.

Corundum, sapphire or α-Al2O3 is an important technological material in many optical and electronic applications such as solid-state lasers, optical windows and, more recently, as a radiation detector. Landauer (Glenwood, IL, USA) accumulated large number of archived and stored Luxel™ dosemeters composed of Al2O3:C, which were subjected to a recovery process. Due to the importance of this advanced crystalline material in OSL dosimetry, a recovery process was developed based on the dosemeters calcination and Al2O3:C has been reused in manufacturing of new dosemeters. This paper does not aim to optimize the recovery process, but provides an opportunity to study the involved process parameters and to recover this valuable crystalline material from used dosemeters. To the best of our knowledge no other recovery process involving this dosimetric material was described in scientific literature. Fourier Transform Infrared Spectrometry (FTIR), Thermogravimetry/Differential Thermoanalysis (TG/DTA), Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), Optically Stimulated Luminescence (OSL) and Rietveld Refinement were used to characterize the recovered material and to check for the stability of its structural and dosimetric properties.

Este trabalho descreveu as características sociodemográficas de trabalhadores de saúde, seu trabalho e a incidência de afastamento por doença de um hospital público do Estado da Bahia no período de 1º de julho de 2005 a 30 de junho de 2006. Os dados foram coletados nas pastas cadastrais do setor de pessoal, nos atestados médicos de até 15 dias de afastamento e em documento da Secretaria Estadual de Saúde. Observou-se uma média de 2,31 atestados médicos por trabalhador. Dos 837 profissionais da equipe de saúde, 31,9% afastaram-se por doença pelo menos uma vez no período. Destes, 91,0% são do sexo feminino; 60,7% possuem idade ≥ 40 anos; 60% possuem tempo de serviço na instituição ≥ 12,5 anos; 70% eram estatutários; 59,5% tinham jornada de 40 horas semanais. A maioria dos afastados estava lotada na Emergência e na UTI e era do grupo de Enfermagem. Espera-se que este estudo fomente novas discussões sobre as características do trabalho em hospitais e estimule a implantação de serviço de atendimento à saúde do trabalhador no hospital estudado e a realização de novas investigações.

This work describes the socio-demographic characteristics of health care workers, their work, and the incidence of sick leave in a public hospital in the State of Bahia, Brazil during the period between July 1, 2005 and June 30, 2006. Data was collected from the personnel department register, from doctors' statements for the leave, and from a document issued by the Bahia State Health Department. The results showed an average of 2.31 doctors' statements per worker. Among 837 workers, 31.9% were absent at least once due to illness, during the mentioned period. Of these, 91.0% were women; 60.7% ≥ 40 years old; 60% had been working at the institution for ≥ 12.5 years; 70% were permanent civil servants covered by a specific pay system; 59.5% worked 40 hours a week. Most of the absentees belonged to the nursing staff and worked either in the emergency ward or in the ICU. We expect that this study will encourage new discussions on the characteristics of hospital work, will incite the implementation of workers' health services in the hospital studied and new research on the issue.
