Noise pollution inside buildings is caused by sound reflection from  internal surfaces. The purpose of the study is to experimentally study the sound emission pattern based on acoustic characteristics in industrial manufactorys.

In manufactorys, rectangular cubes with a volume of less than 2000 cubic meters, between 2000 to 3000 and 3000 to 4000 were made. The reverberation time measurement was based on ISO 2-3382:2008 and the sound emission pattern was measured according to ISO 11690 and the sound level was measured with pink noise. In order to simulate sound parameters, radiation tracking was used in Odeon. Data analysis was done with Spss.

The average reverberation time in manufactorys under 2000, between 2000-3000 and between 3000-4000 cubic meters was 1.75, 2.25 and 2.77 seconds , the measured reverberation time had a significant correlation with the predicted one (r=0.95). The average sound reduction with the distance from the source is 4, 3 and 3 dB, the correlation coefficient between the sound reduction level and the reverberation time (r=-0.97), the correlation between the measured and predicted sound level(r=0.95) was determined.

The reverberation time of the Sabin and Eyring showed higher values than the measurement method. There was a significant relationship between the average noise reduction pattern and the reverbration time. simplicity of the measurement method, the sound reduction criterion can be a good criterion to show the sound emission pattern. It should be used together with the reverberation time to evaluate the sound emission pattern in the manufactorys.

The aim of this study was to compare the effect of dialectical behavior therapy combined with medication and medication on emotion regulation, self-control and cognitive flexibility in people with bipolar disorder.

Which is a quasi-experimental method with pre-test design, dual post-test. The statistical population consisted of all patients with a definite diagnosis of bipolar disorder hospitalized in Ibn Sina Hospital in Mashhad in 2020, 30 of whom were selected by available sampling method based on inclusion criteria and randomly divided into two groups of 15 people A and B experiments. Were. Both groups completed the Garnfsky Emotional Regulation Questionnaire, Dennis et al. Cognitive Flexibility, and Tanji et al. Self-Control Questionnaire. During the same period, experimental group B used only lithium carbonate. Both groups completed the above tests again and analysis of covariance was used to deduce the hypothesis.

The results showed that the difference between dialectical behavior therapy and drug therapy There is a difference in emotion regulation, self-control and cognitive flexibility in people with bipolar disorder and the effect of dialectical behavior therapy is greater with medication (P˂ 0.01).

The results of this study show that this therapeutic approach can be used in combination with medication to reduce the problems of bipolar patients.Keywords: Dialectical Behavior Therapy, Drug Therapy, Emotion Regulation, Self-Control, Cognitive Flexibility, Bipolar Disorder

In this study, the ability of three rangeland species Atriplex halimus, A. canescens and A. lentiformis to remove nitrate from soil in vitro (greenhouse) in a completely randomized design was investigated. For this purpose, potassium nitrate salt (KNO3) was used in four treatments control, 6.3 ppm, 9.5 ppm and 14.5 ppm in three repetitions. Plant species used in this study with an approximate age of 6 months were prepared from the village of Chaparquimeh, Gonbad Kavous city in Golestan province. Selected species were cultivated in nitrate-contaminated soils with the concentrations mentioned and after a period of three and six months, the amount of dry weight and nitrogen of aerial and underground organs of the species and the amount of nitrate in the soil were measured. With increasing salt concentration from 6.3 ppm to 14.5 ppm, the amount of dry weight of aerial parts in A. canescens  has decreased from 28.31 ppm to 14.05 ppm, in A. halimus from 28.83 ppm to 11.75 ppm and in A. lentiformis from 39.17 ppm to 16.05 ppm . A downward trend was observed in the amount of dry weight of underground organs in the studied species, so that by increasing the salt concentration from 6.3 ppm to 14.5 ppm, the amount of underground dry weight in A. canescens  from 8.31 ppm to 5.05 ppm, in A. halimus from 6.83 ppm to 4.75 ppm and in A. lentiformis decreased from 10.17 ppm to 6.47 ppm. The results of study showed that the level of soil nitrate removal at different concentrations decreased in all three species. The percentage of soil nitrate removal efficiency by A. canescens at concentrations of 6.3 ppm, 9.5 ppm and 14.5 ppm is 71%, 52% and 37%, respectively, by A. halimus are reported to be 62%, 45% and 38%, respectively. However, A. lentiformis removed nitrate at a higher level than the other two species with 80%, 64% and 47%, respectively. The results showed that with increasing the concentration of this contamination in the soil, the phytoremediation capacity of the studied species decreased and A. lentiformis with high nitrogen storage in its tissues has an effective role in clearing nitrate-contaminated soils.
