Abstract
Background and Aim: Organizations should know that if the mouths of organizations are silenced, there will be a decrease in productivity and performance in human capital. The present study was conducted to identify the relationship between managers' organizational silence and human resource productivity in one of the military-medical universities in Tehran, Iran.
Methods: In the present cross-sectional study, all managers of the military medical university were studied by the census. The standard questionnaires of human resource productivity of Hersey and Goldsmith Model and the questionnaire of organizational silence "Salavati et al" were used. Data analysis was performed using SPSS software version 21.
Results: Pearson correlation coefficient between the two variables of organizational silence and human resource productivity is equal to -0.590 and is significant. There is a significant inverse relationship between the two variables of silence and productivity of human resources (P<0.05). In other words, with increasing silence, the productivity of human resources decreases significantly.
Conclusion: Considering the inverse relationship between silence and productivity, managers are recommended increasing the participation of employees in organizational decisions and reduce the level of organizational hierarchy, to reduce organizational silence and increase productivity in the organization.

Abstract
Background and Aim: Zinc is one of the heavy metals in aquatic ecosystems. Currently, nanotechnology has made significant progress in various industries, in the present study, the toxicity of nano-zinc oxide on the blood indices of Capoeta capoeta gracilis (Capoeta) was investigated.
Methods: This research was conducted with concentrations of 0, 5, 20, 100 and 400 mg/L of nano-zinc oxide (Nano-ZnO) for 14 days on 70 Capoeta with a mean weight of 20±5 grams. After the experiment, blood samples were taken from the Capoeta and various blood indices were measured including leukocytes, lymphocytes, neutrophils, eosinophils, erythrocytes, hemoglobin, hematocrit, MCV, MCH and MCHC.
Results: All blood erythrocyte indices in Capoeta showed significant changes, but leukocyte indices did not change. Also, with the increase of nano-zinc oxide in different treatments, the number of red blood cells, hemoglobin and hematocrit decreased and the number of white blood cells increased in Capoeta.
Conclusion: With rising the concentration of nano-zinc oxide, the level of hematological adverse effects increased and the concentration of 100 mg/l has the most adverse effects in Capoeta. Nano-zinc oxide causes anemia and disrupts Capoeta's immune system, which may be due to its destructive effects on hematopoietic organs such as the liver and kidney.
