Effect of zeolite on saturated hydraulic conductivity and crack behavior of silty clay paddled soil     

Zahra Razmi 《Archives of Agronomy and Soil Science》2013,59(7):805-816

The addition of zeolites to soil modifies soil physical and chemical properties. The objectives of this research were to study the effect of zeolite on saturated hydraulic conductivity, K _s, and crack behavior in a silty clay paddled soil. Soil samples were mixed with 0, 4, 8 and 12 g kg^?1 of zeolite for K _s determination, and 0, 2, 4, 8 and 12 g kg^?1 for soil crack measurements. Saturated hydraulic conductivity was measured using the constant head method. The results indicated that K _s was significantly increased at a zeolite application rate of 8 g kg^?1. Furthermore, an increase in zeolite content up to 8 g kg^?1 decreased soil crack area after paddling and first rewetting. Higher amounts of zeolite (e.g. 12 g kg^?1) increased crack density after the second rewetting. However, a 50% reduction in crack depth occurred with zeolite application rates of 8 and 12 g kg^?1 in comparison with controls. Thus, a zeolite application rate of 8 g kg^?1 is recommended for soil crack reduction in intermittent-flood irrigation. Furthermore, a relationship was obtained between crack area density (Ln), gravimetric soil water content and zeolite application rate. After the second irrigation, a relationship was also obtained between crack depth, gravimetric soil water content and zeolite application rate. Crack depth showed a positive and highly significant linear correlation with crack width.  相似文献

A case of dorso-medial luxation of the radial carpal bone in a dog     

S Palierne  C Delbeke  E Asimus  P Meynaud-Collard  D Mathon  A Zahra  A Autefage 《Veterinary and comparative orthopaedics and traumatology》2008,21(2):171-176

Luxation of the radial carpal bone is an uncommon injury in the dog and cat. Previous clinical cases have reported palmaro-medial luxation with injury to the short radial collateral ligament. In this study a case of dorsomedial luxation of the radial carpal bone in a 10-year-old female Gordon Setter is described. A closed reduction of the luxation was performed and a conservative treatment was carried out. Thirteen months after the reduction, the dog had a satisfactory limb function, despite the presence of degenerative joint disease of the carpus. A pathogenic hypothesis for this dorso-medial luxation of the radial carpal bone is proposed reproducing the luxation on canine cadavers.  相似文献   

Protection by cAMP and cGMP phosphodiesterase inhibitors of diazinon-induced hyperglycemia and oxidative/nitrosative stress in rat Langerhans islets cells: Molecular evidence for involvement of non-cholinergic mechanisms     

Zahra Ghafour-Rashidi 《Pesticide biochemistry and physiology》2007,87(3):261-270

The objective of this study was to study the effects of acute administration of diazinon alone or in combination with two phosphodiesterase (PDE) inhibitors with selectivity to cAMP and cGMP (theophylline and sildenafil, respectively) on oxidative/nitrosative stress biomarkers, including nitric oxide (NO), lipid peroxides (TBARS), total antioxidant power (TAP), and concentration of tumor necrosis factor (TNF-α) in isolated Langerhans islets, plasma glucose and insulin levels, and the activity of plasma cholinesterase (ChE). Examination by different doses of diazinon (15, 30, and 60 mg/kg) in single administration lead us to choose diazinon (30 mg/kg) in combination therapies. Theophylline and sildenafil were used at doses of 25 and 5 mg/kg, respectively. In all diazinon-treated groups, plasma ChE activity and plasma insulin level were significantly decreased and plasma glucose concentration and Langerhans islets TNF-α, TBARS, and NO levels were significantly increased in comparison to controls. The TAP did not change in comparison to control. In combination therapy, both theophylline and sildenafil restored diazinon-induced changes in plasma glucose concentration, Langerhans islets TNF-α, NO, and TBARS concentrations but Langerhans islets TAP, plasma insulin, and ChE levels. It is concluded that diazinon stimulates oxidative/nitrosative stress in Langerhans islets that results in hyperglycemia due to insufficiency of insulin. Altered glucagons/insulin ratio, activated hepatic glucose production/release, and insulin resistance are possible mechanisms. The protective effects of cAMP and cGMP PDE inhibitors in restoration of diazinon-induced oxidative/nitrosative stress and hyperglycemia stress back to their antioxidant potentials that seem to be independent of ChE inhibition.  相似文献   

Distal Renal Tubular Acidosis in an Iranian Patient with Hereditary Spherocytosis     

Zahra Shahab-Movahed  Ahmad Majd  Elham Siasi Torbati  Sirous Zeinali 《Iranian Biomedical Journal》2021,25(5):359

Background:Hereditary spherocytosis and hereditary dRTA are associated with mutations in the SLC4A1 gene encoding the AE1. In this study, some patients with clinical evidence of congenital HS and renal symptoms were investigated. Methods:Twelve patients with congenital HS and renal symptoms were recruited from Ali-Asghar Children’s Hospital (Tehran, Iran). A patient suspected of having dRTA was examined using WES method, followed by Sanger sequencing. Results:One patient (HS03) showed severe failure to thrive, short stature, frequent urinary infection, and weakness. A homozygote (rs571376371 for c.2494C>T; p.Arg832Cys) and a heterozygote (rs377051298 for c.466C>T; p.Arg156Trp) missense variant were identified in the SLC4A1 and SPTA1 genes, respectively. The compound heterozygous mutations manifested as idRTA and severe HS in patient HS03. Conclusion:Our observations, for the first time, revealed clinical and genetic characteristics of idRTA and severe HS in an Iranian patient HS03. Key Words: Erythrocyte membrane protein, Hereditary spherocytosis, Hemolytic anemia, Whole-exome sequencing  相似文献   

Forest Road Detection Using LiDAR Data     

Zahra Azizi  Akbar Najafi  Saeed Sadeghian 《林业研究》2014,25(4):975-980

We developed a three-step classification approach for forest road extraction utilizing LiDAR data. The first step employed the IDW method to interpolate LiDAR point data （first and last pulses） to achieve DSM, DTM and DNTM layers （at 1 m resolution）. For this interpolation RMSE was 0.19 m. In the second step, the Support Vector Machine （SVM） was employed to classify the LiDAR data into two classes, road and non-road. For this classification, SVM indicated the merged distance layer with intensity data and yielded better identification of the road position. Assessments of the obtained results showed 63% correctness, 75% completeness and 52% quality of classification. In the next step, road edges were defined in the LiDAR-extracted layers, enabling accu- rate digitizing of the centerline location. More than 95% of the Li- DAR-derived road was digitized within 1.3 m to the field surveyed nor- rnal. The proposed approach can provide thorough and accurate road inventory data to support forest management.  相似文献   

Pharmacokinetics of carprofen and firocoxib for medication control in racing greyhounds     

TH Morris  SW Paine  PW Zahra  EC Li  SA Colgan  SL Karamatic 《Australian veterinary journal》2020,98(12):578-585

Animals used in sport should be treated as required to ensure animal welfare but any such use of medication should also be controlled to ensure integrity. Pharmacokinetic studies on groups of six greyhounds were performed to measure plasma and urine levels of carprofen and firocoxib to inform medication control advice. Using the standard methodology for medication control the Irrelevant Plasma Concentration was determined as 20 and 2 ng/mL for carprofen and firocoxib, respectively. The Irrelevant Urine Concentration was also determined as 0.3 and 2 ng/mL for carprofen and firocoxib, respectively. These Irrelevant Plasma and Urine Concentrations will allow laboratory Screening Limits, Detection Times and Withdrawal Time advice to be determined and publicised by regulators of greyhound racing. The Screening Limits will also inform Recommended Limits of Detection if meat-containing residues of these medications are fed to greyhounds.  相似文献
