The dam is a multipurpose earth fill dam with a storage capacity of 11.11 million cubic meters, which was in operation since 1986. During the first impounding of its reservoir, seepage of water underneath the foundation of dam was noticed due to the desolation of gypsum beds. This raised concern about the stability of the dam and since then grouting operation were carried out. ISIS occupied the dam 8 - 16 August 2014. Grouting operations stopped and number of equipment and buildings were destroyed during that short period. After the defeat of ISIS, the Iraqi Ministry of Water Resources rebuilt and constructed the destroyed parts within the site and a new maintenance operations program was adopted. New training courses for the staff of Mosul Dam were conducted with Trevi Company and US Army Corps of Engineers. In this paper, the dye test is highlighted to monitor the seepage of groundwater within the dam site. It seems that the dam is stable in its present conditions and water level height.展开更多

Routine HSG may result in loss or damage to the hymen and loss of virginity. Aim: The aim of the procedure of retrograde dye test was explored to see the possibility of assessing tubal patency during laparotomy. Case Presentation: At laparotomy and after myomectomy in a 32 year old virgin, a moderate sized Wilkinson’s cannula was gently inserted at the fimbrial end of the both tubes and 50mls of dilute Methylene-Blue solution was injected in each tube at a time to see whether the dye will appear at the vagina introitus. There was no resistance to flow of the dye in both tubes. Inspection of the vaginal introitus revealed a gush of dye flowing through it as the dye was introduced through each tube confirming the patency of both tubes. Conclusion: Retrograde dye test at the time of abdominal procedures like myomectomy, pelvic adhesiolysis and excision of endometriotic cyst can be cost effective. This procedure is also useful in assessing tubal patency for women who undergo laparotomy and also wish to preserve their virginity.展开更多

The experimental results revealed that under the optimum Fenton oxidation conditions （initial pH 5, H 2 O 2 dosage 17 mmol/L, and Fe^ 2＋ 1.7 mmol/L） the average total organic carbon （TOC） and color removal ratios were 39.3% and 69.5% after 35 min of reaction, respectively. Results from Zahn-Wallens Test also represented that Fenton process was effective to enhance the biodegradability of the test wastewater. As for the further purification of MBR process, TOC removal capacity was examined at different hydraulic retention times （HRT） of 10, 18 and 25 hr. Under the optimum HRT of 18 hr, the average TOC concentration and color of the final MBR effluent were 16.8 mg/L and 2 dilution time, respectively. The sludge yield coefficient was 0.13 g MLSS/g TOC and TOC degradation rate was 0.078 kg TOC/（m ^3 ·day）. The final effluent of MBR can meet the reuse criteria of urban recycling water – water quality standard for miscellaneous water consumption GBT18920-2002.展开更多

[Methods]Three factors affecting dyeing were selected including pH,concentration of dye and dyeing time. The L_9(3~3) orthogonal design was used to evaluate the hair coloring effect and the absorbance of cleaning solution after hair was dyed. [Results] The optimum pet dog dyeing process of plant hair dye was dye concentration of50 mg/mL,dye pH of 7. 5 and dyeing time of 1 h. [Conclusions] The coloring and fixing effects of the dye and dyeing process are good,which can lay a foundation for the development and utilization of plant dyes.展开更多
