Objectives To gain the perspectives of patients who underwent lumbar spinal stenosis (LSS) surgery and physical therapists who treat spine-related disorders regarding rehabilitation and other care prior to LSS surgery. Design Qualitative focus group study. Methods Sixteen patients (4 female; average ± SD age, 64.3 ± 8.8 years; time since surgery, 9.9 ± 4.4 months) and 10 physical therapists (2 female; average ± SD age, 40.9 ± 6.6 years; time in practice, 17.2 ± 7.7 years) participated. Four groups were conducted: 2 with patients post LSS surgery and 2 with physical therapists who treat spine-related disorders. Participants were asked open-ended questions by a trained facilitator regarding their perceptions of preoperative LSS education and rehabilitation. Transcripts were coded and themes were identified. Results Analyses revealed 4 themes within the discussions: (1) desire for helpful information, (2) benefits of preoperative rehabilitation, (3) downfalls of preoperative rehabilitation, and (4) desire for coordinated care. Varying opinions on preoperative physical therapy between patients and physical therapists were discussed, revealing that similar numbers of participants held positive and negative perceptions of preoperative physical therapy. A desire for more thorough preoperative education and care was expressed by both groups. Conclusion There is a clear need for standardized preoperative LSS care and education. This may decrease misunderstandings about LSS surgery and its treatments in the future as well as improve coordinated care between surgeons and physical therapists.

Published: October 2019

Oil and gas industry produces wastewater (produced water), which contains hydrocarbons, heavy metals, and other components, such as mineral salts essential for plant nutrition. Hydrocarbons presence on produced water limits its potential use in the agriculture, as its lead to inhibition of plant growth. The present study aimed to investigate the effect of hydrocarbons analogous contained in the produced water on 1) pH and electrical conductivity (EC) of irrigation leachate, 2) plant´s morphological variables, 3) mineral concentration, 4) fruit pH, EC and total dissolved solids (TDS), during flowering and fruiting stages in tomato grown into greenhouse conditions. As source of produced water were used diesel at concentrations of 20 and 25 mg L‑1, gasoline at 40, 50 and 60 mg L-1, and benzene at 75 mg L-1, applied in the substrate by means of a syringe. All plants treated with hydrocarbons reached the fruit setting and ripening stage at the 6-cluster. Depending on their type, concentration, and exposure time, hydrocarbons modif ied the pH and EC of the irrigation leachate, caused signif icant morphological changes with longer exposure time, and restricted the biomass production. Mineral concentration differed signif icantly among plant organs, affecting mainly the sodium uptake in stems and fruits. The variables of fruit quality, EC and TDS were favorably modif ied by most treatments.
General inbreeding coefficient of maize synthetics derived from three-way line hybrids

Published: October 2019

The scarcity of pure and unrelated maize inbred lines that possess high combining ability in Mexico has led breeders wishing to form single crosses to develop double-cross or three-way line hybrids (TWLHs) instead. However, some of the farmers who grow these hybrids cultivate their advanced generations later on. Although the resulting populations can be viewed as the synthetics that the random mating of the parental lines (SynL) of these hybrids would produce, there may be differences. The synthetic variety whose parents are t TWLHs (SynT) is interesting because the contributed gene frequencies of the three lines that are parents of a TWLH are not balanced and this may generate a difference between the inbreeding coeff icients (ICs) of the SynL and SynT. Since an unbiased and general inbreeding coeff icient of the SynT and a prediction formula for the SynT genotypic mean (GM) are not yet known, the objective of this study was to derive formulae for these two important parameters of SynT. To form the t TWLHs, it was assumed that 3t unrelated lines whose IC was F (0 ≤ F ≤ 1) were used. Unbiased and general formulae for FSynT and GM were derived for the f irst time. In particular, it was found that FSynT = [3(1 + F)]/(16t). Since the inbreeding coeff icient of the SynL derived from the same 3t lines is (1 + F)/(6t), then FSynT > FSynL. These f indings suggest that the genotypic mean of the SynL grain yield is larger than the SynT’s.

Published: October 2019

Esse artigo tem como objetivo contextualizar a transição do modelo de administração pública burocrática para o modelo de administração pública gerencial no Brasil à luz da implementação do Plano Diretor da Reforma do Aparelho do Estado - PDRAE. O estudo baseia-se em fontes primárias e secundárias sobre o tema e procura apontar o que efetivamente foi realizado após a formalização do plano de mudanças na gestão pública, implementado no âmbito do Ministério de Reforma do Aparelho do Estado - MARE. Conclui que mesmo que boa parte das ações propostas para alcançar os objetivos do Plano tenha sido postas em prática, e sucessos alcançados, é fato que a Reforma não está completa, existindo ainda resquícios do patrimonialismo e da burocracia que ainda travam a prática eficiente da administração pública gerencial no Brasil.
WINTER HARDINESS OF BREAD WHEAT FROM THE VIR COLLECTION IN ENVIRONMENTS OF THE NORTHWESTERN AND CENTRAL BLACK SOIL REGIONS OF RUSSIA

Published: October 2019

Background. Winter wheat resistance to adverse winter­ing conditions is one of the most important adaptive charac­teristics. To obtain high yields, modern wheat cultivars should have various protective reactions. For their success­ful combination in one genotype, the availability of appro­priate initial material is of great importance. In Russia, the accessions from the VIR collection are traditionally used as initial material for wheat breeding. The aims of the present study were (1) to evaluate winter hardiness in accessions from the VIR collection in a field test, and (2) to use the ob­tained data and those on the geographical origin of acces­sions for making up the target sub-collection and perform­ing its eco-geographical studies.Materials and methods. The initial sample for field screening contained 431 acces­sions of common winter wheat from different regions of Russia and the former USSR, and 484 accessions from 18 foreign countries. Winter hardiness of these accessions was tested in the environmental conditions of the North­western region (Pushkin, 59°41′N 30°20′E, 2006/2007, 2007/2008 and 2013/2014) and of the Central Black Soil re­gion (Yekaterinino, 52°59′N 40°50′E, Tambov Province, 2007/2008 and 2008/2009). The degree of winter hardi­ness was determined in accordance with the technique de­veloped at VIR.Results and conclusions. In 2006/2007, in Pushkin, a high and a very high degree of winter hardiness was displayed by 114 accessions with the origin from Rus­sia and the former USSR as well as by 12 accessions from foreign countries. Based on the obtained data and taking into account the diversity of the geographical origin of ac­cessions, the target sub-collection was formed, whose ac­cessions were subjected to eco-geographical two-year field studies (Pushkin, 59°41′N 30°20′E, 2007/2008, 2013/2014, and Yekaterinino, 52°59′N 40°50′N, Tambov Province, 2007/2008, 2008/2009). The Friedman’s variance analysis has shown that variation on winter hardiness in 158 acces­sions from the target sub-collection was determined by the environmental conditions of wheat cultivation (χ2э = 256.7; df = 4; χ2W=0.05 = 9.5) and by genetic differences between ac­cessions (χ2э = 239.3; df = 157; χ2W=0.05 = 187.2) at that effect of the prior was stronger than that of the latter. By using the cluster analysis (k-means algorithm), the target sub-collec­tion structure has been revealed. Twelve accessions that overwintered well at both geographical locations during all the years of testing were identified.
