Rainwater was harvested in July, 2012. Water quality of runoff and cistern water after storage was measured, including turbidity, chemical oxygen demand （COD）, total nitrogen, nitrate, and ammonia. Results show that pollutant concentrations in runoff decreased with time, indicating that runoff in the early time should be removed. Nitrate concentrations in cistern water increased after storage, while the remaining parameters decreased. Measured pollutant concentrations did not exceed the limit according to the standard for drinking water in China. It can be concluded that the solidified soil cistern with plastic mixture construction technology can provide available water for domestic use.展开更多

This experiment was carried out in 2006, in North Tunisia, using a randomized block design per udder cistern size, using 60 Holstein cows. Cows were classified according to udder cistern size by ultrasonography as large-cisterned （44 ±13 cm2; LC） and small-cisterned （21 ± 8 cm2; SC）. The experiment was carried out in two different periods： spring （Apr. 5 （D1）） and summer （July 19 （D2）, Aug. 19 （D3） and Sept. 19 （D4））. On each test day, temperature and relative humidity data were registered hourly and cows＇ blood was sampled from the jugular vein to determine serum concentrates of cortisol and T4. Leucocytes （lyrnphocytes, eosinophils, neutrophils and monocytes） were counted differentially, and percentages of lymphocytes relative to total counted cells were calculated. Mean temperature-humidity index （THI） values were 62 ±2, 79 ±2, 84 ±2, and 77 ±1 in DI, D2, D3, and D4, respectively. Lymphocyte incidence relative to total cell counts and T4 concentrations were affected by test day （P 〈 0.001）. Lymphocytes （%） were significantly less in hotter months. During summer, T4 concentration at D2 （87.4 nmol/L） was higher relative to concentrations at D3 （42.8 nmol/L） and D4 （53.5 nmol/L）. T4 concentrations were higher （P 〈 0.01） in SC cows （67.7 ±0.1 nmol/L） compared to LC cows （52.7 ±0.1 nmol/L）. Cortisol concentration was effected neither by test day nor by cistern size. However, the decrease of lymphocyte concentration during summer compared to spring could be considered as an evidence of the suppression of cows＇ immune system under heat stress.展开更多

A rainwater cistern is a way to improve wildlife habitat because it can be situated in locations that do not have natural water sources, such as streams or wells that can supply water for storage. However, the design and sizing of such a system can be challenging because a number of constantly varying factors must be considered, such as changing precipitation patterns, the evaporative losses from the cistern and </span><span style="font-family:Verdana;">animal water consumption. No standardized sizing methodology currently</span><span style="font-family:Verdana;"> exists for designing wildlife rainwater cisterns. In this article we present a new method for assisting in optimally sizing a rainwater cistern. We discuss how we implemented the quantitative portion of this methodology into a new Excel? model called CISMOD, which we configured for general use by wildlife professionals. We describe the methodology for designing a rainwater cistern based on standard engineering techniques. We then present and discuss our experience in applying the model to design two rainwater cisterns in an area of the Jemez Mountains in northern New Mexico, USA. The CISMOD model and a user manual are available at no cost for wildlife professionals.展开更多

Methods: from November 2019 to November 2020, 37 patients with communicating hydrocephalus received in the hospital were randomly selected for lumbar cistern abdominal shunt. Results: of the 37 patients, 30 needed pressure regulation immediately after the operation, and the maximum number of times of pressure regulation was four. After surgical treatment, the overall symptoms of the patients showed signs of improvement, among which 22 patients' conditions were significantly relieved. After the operation, the head CT examination was performed on the patients. The enlarged ventricles of the brain eventually showed significant reduction, and the interstitial edema was relieved. Among them, 25 patients recovered and returned to normal values. After the operation, there was one patient with infection, and the patient gradually recovered after antibiotic treatment. Of these 37 patients, 18 had excessive shunting and 12 had insufficient shunting, all of which improved after pressure adjustment. Conclusion: for patients with communicating hydrocephalus, lumbar cistern abdominal shunt is effective.展开更多

The GOS of the patients 3 months after trauma were regarded as outcome.Results: The rate of unfavorable outcome ( dead, vegetative status, severe disability ) was significantly correlated with perimesencephalic cistern narrower than 1mm (P < 0.05), especially narrower than 0.5 mm (P < 0.005), deformed midbrain (P< 0.005) or abnormal ratio ( < 0.9 or >.1) of the occipitofrontal diameter and transverse diameter of the midbrain (P < 0.01). But the patient's perimesencephalic cistern wider than 1mm and the patients without deformed midbrain got favorable outcome (moderate disability/good recovery).Conclusions: The state of the compressedperimesencephalic cistern ( < 1 mm) and the deformation of the midbrain may significantly indicate unfavorable outcome of the patients with acute craniocerebral injury.展开更多
