Pigmentos fotossintéticos e índice spad como descritores de intensidade do estresse por deficiência hídrica em cana-de-açúcar

The objective of this study was to evaluate the responses of sugar cane subject to water stress by photosynthetic pigments (chlorophylls a, b, total a + b, ratio chlorophylls a/b and carotenoids) and verify the use of SPAD index as a cultivar differentiation tool. The experiment was carried out in a greenhouse, where four cultivars (IACSP95-5000, RB835054, RB928064 and SP80-3280) were grown in pots. After 65 days of planting, two treatments were implemented, i.e., with no stress (-D) and with water stress (D +). Cultivars of sugar cane respond differently in relation to photosynthetic pigments when subjected to water deficit. Cultivars IACSP95-5000 and RB928064 have less effect of drought, that is attributed to the ability of maintaining the chlorophyll and carotenoid content, as well as higher SPAD index values under this condition. Water stress affects with more intensity the cultivars RB835054 and SP80-3280 due to higher reductions in photosynthetic pigments and SPAD index. SPAD index is correlated with chlorophyll and carotenoid content in sugar cane and can be used as a technique for selecting tolerant cultivars to drought in breeding programs.

Estudo da prevalência de disfunção craniomandibular segundo o índice de Helkimo tendo como variáveis: sexo, faixa etária e indivíduos tratados ou não ortodonticamente

One hundred non-patient dentistry students aged 17 to 25, were interviewed through questionnaire and were clinically examined in order to asses the prevalence and degree of severtty of Craniomandibular Dysfunction, through indeces which are subdivided into three classes: anaminestic index, clinical dysfunction index, and occlusal index. The following variables were introduced to the original indeces: sex, age, and whether the subjects had or had not received orthodontic treatment. The results showed that 42% of the subjects presented mild subjective symptoms whereas, no one showed severe subjective symptoms. Women, as well as the older subjects, showed a higher trend to presenting more subjective complaints. Subjects, whether treated orthodontically or not, showed a similar trend to having dysfunction symptoms. Fifty-six per cent of the subjects presented some score of clinical dysfunction, 25% of them showed moderate or severe clinical dysfunction. Women showed a statistically significant higher index. The older subjects trented to have indeces with more severe degrees. Orthodontic treatment suggested to have no influence on the clinical dysfunction index. Sixty-six per cent of the subjects showed a mild occlusal index and 11% a severe occlusal index. Sex, age, and orthodontic treatment did not show any significant difference as to the presence or absence of malocclusion

Cursos superiores de tecnologia: igualdade jurídica e dualidade na escola

Since the 1990s, higher education technology courses in Brazil have greatly expanded the offer of courses and places. However, the high dropout rates presented in these courses led to a research in order to uncover the factors that lead students to dropout. Through literature review and desk research, this study makes a historical analysis of how professional education is conducted in Brazil. This paper seeks to demonstrate that the implementation of public policies for professional education exacerbates the school’s duality. However, such duality generates contradictions between subjective and objective issues produced by the ideology disseminated by public policies and government actions in relation to vocational education. These contradictions end up unveiling the social inferiority of vocational education and discourage students from remaining in the courses. The legal equality between educational levels seeks to mediate the emergence of these contradictions. However, despite legal equality, social equality is not achieved in the implementation of public policies, leading to a high dropout rate.
