3Impact of Flow Rate in Integration with Solar Radiation on Color and COD Removal in Dye Contaminated Textile Industry Wastewater:Optimization Study显示文摘Dyes are an integral part of the dying industry and have significantly resulted in environmental pollution by altering the standardwater quality after their discharge into the water bodies.The culprits behind the altered water quality are the pretreatment chemicals used during dying manufacturing processes.Various advanced treatmentmethods using conventional and advanced treatment options including solar energy have been put forth by researchers for the treatment of the dying effluents but,these methods have not proved significantly considerable.Therefore,the present study intends to check the efficiency of solar parabolic trough collector for treating the dying effluents in terms of color and COD.However,other wastewater parameters(BOD,nitrate and phosphate)have also been considered for this experimental analysis.Four standard flow rates(0.5,1.3,1.95 and 2.6 L/M)were maintained during the experiment for six hours at solar intensity(849.3±21.2W/m^(2))and the optimized flow rate(1.95 L/M)was detected and considered for further study during the present experiment.The color concentration showed a significant reduction(≥76.4%)by treatment with the designed solar reactor.Similar significant results were also noticed in terms of COD(79%).In this context,the current experimental study provides ideas on the decolorization and COD reduction efficiency with optimal flow rate in terms of cost-effectiveness with designed experimental reactor which could be further used and implemented for advanced scientific purposes.Pradeep K.Majhi Rifat Azam Richa Kothari Naveen Kumar Arora V.V.Tyagi 2022Energy Engineering2022,119,1:0
4Clinical pregnancy rate of women with unexplained infertility with or without cervical mucus aspiration before intrauterine insemination: A randomized controlled trial显示文摘Objective:To detect effect of removing cervical mucus before performing intrauterine insemination(IUI)on pregnancy rate in patients with unexplained infertility.Methods:The randomized controlled trial was conducted in Infertility Division of Department of Obstetrics and Gynaecology of a tertiary care hospital.Totally 80 patients of unexplained infertility were recruited.By computer generated block randomization in block size of 4 and 6,patients were randomly allocated at time of starting ovarian stimulation into the cervical mucus removal group or the non-removal of cervical mucus group before IUI,40 in each group.Ovarian stimulation with clomiphene 100 mg from day 2-6 of menstrual cycle along with human menopausal gonadotropin 150 IU was given alternate day starting from day 7.Follicular monitoring was done and further doses given as per response;trigger was planned when 1-3 follicle reach a diameter of>18 mm.IUI was planned after trigger.IUI was done as per the group allocated.Mucus cleaning was done in the cervical mucus removal group by aspirating mucus with IUI syringe and sterile cotton swab before IUI.The primary outcome was clinical pregnancy rate.Number of difficult IUIs and cycle cancellation due to ovarian hyperstimulation were also noted.Results:IUI was not done in 4 patients due to hyperstimulation.Pregnancies per IUI cycle occurred in 7.9%(3/38)in the cervical mucus removal group and 21.1%(8/38)in the non-removal of cervical mucus group.There was no statistically significant difference in clinical pregnancy rate between two groups(P=0.19).Conclusions:There is a trend towards a lower clinical pregnancy rate with removal of cervical mucus before IUI in women of unexplained infertility though the difference is not statistically significant.Further studies with large sample size need to be done on this intervention.Richa Vatsa Vanita Suri Shalini Gainder Aashima Arora Japleen Kaur Neelam Choudhary Shruti Sharma 2022Asian pacific Journal of Reproduction2022,11,6:0
