ABSTRACT
Aim: There is evidence that health care providers have insufficient knowledge and poor practices regarding the use of surgical mask. Therefore, this study aimed to explore the knowledge, practices and attitudeof healthcare providers about using face mask in order to limit the spreading of the novel coronavirus disease.Methodology:This was a cross sectional pilot study included a questionnaire about the knowledge of health care workers regarding the use of surgical face mask to prevent the new COVID-19 spreading and about their practices and the attitude of them regarding the use of surgical face mask to limit the new COVID-19 exposure Results: About 86.21% of health care workers said that the correct way ofusing surgical face maskisWhite side facing in and about 65.52% of them said that N-95 mask is the mask type that actually protect against COVID-19. All of the respondents reported that they wear a mask in public places to protect themselves against COVID-19 and that they wear a mask in hospital premises to protect themselves against COVID-19 (100.00%).Conclusion: The Knowledge, attitude, and practice of health care providers regarding the use of surgical face masks were found to be good but still more knowledge is required about several aspects such as the types of masks, the duration of using masks and the disposal of the masks
ABSTRACT
The objective of this research was to evaluate the incidence of damage by the leafworm Alabama argillacea (Hübner) on yields of cotton grown under rows spaced 0.38 m and 0.76 m at the irrigation area of Santiago del Estero, Argentina. The period evaluated was extended from first flower to first open boll. Treatments were T1 - without control of larvae, T2 - with control of larvae, T3 - control since first flower to the end of effective blooming, and T4 - with larval control since the end of effective blooming to first open boll. The effect of injuries on the crop was evaluated trough boll cotton yield. Larvae were sampled in a weekly basis and insects were present from the first flower until harvest. Populations of A. argillacea decreased crop yields in the two distances tested, by decreasing the weight or number of open bolls.
