It has been proposed that irreversible responses of organisms exposed to contaminants are due to a systems-level feedback. Here we tested this hypothesis by reanalyzing the published data on toxicokinetics and survival probability based on a systems-level threshold damage model (TDM) incorporating with a positive damage feedback to explore the steady-state response and dynamic behavior of damag...

Soybean is largely cultivated worldwide providing high amounts of proteins and oil for food feed, isoflavones nutraceutical uses. The increasing interest in agroforestry practices improving carbon sequestration mitigating climate changes suggests the need to assess soybean response variations light availability direction. A two-year pot trial was carried out at Legnaro (NE Italy) order mimic va...

in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...

Shot peening (SP) is frequently used as a palliative measure against metal fatigue in many engineering components. The performance of this surface treatment depends on different factors including the material, shape and loading conditions component, well process parameters. Fatigue improvement due to SP great extent upon in-depth compressive residual stress profile produced specimen. In work, w...

Background: Root-knot nematodes are known to cause significant damage to eggplants. New approaches by green silver nanoparticles (GSN) are used to control plant-parasitic nematode to avoid chemical nematicide hazards.Objectives: Analyses of the incorporation of different concentrations of nanoparticles on two different algae (Ulva lactuca and Turbinaria turbinata) were carried out. Fureth...

one of the main factors that cause to quality loss for fresh fruit market apples is bruise damage. amongst the factors that affect apple sensitivity to bruising, major one is drop height and area profile during the impact. in the present study, four iranian apple varieties consisted of atirli, kapak, kowse and paiez that were selected and 100 fruits of each variety were picked up, then apples w...

In this paper, a Weibull probabilistic methodology is proposed with an approach to model vibration fatigue damage accumulation using two parameters: distribution and nonlinear model. The cumulated based on the application of stress profile used determine both β η parameters, corresponding component reliability R(t). analyzed accumulate as function for life exponent derived assistance accelerati...

background: cholangiocarcinoma is an invasive biliary malignancy with poor prognosis. diagnostic accuracy of conventional methods is low which is mainly due to the specific anatomy of the disease. the aim of this study was to evaluate the diagnostic value of biochemical profile and tumor marker of the bile in patients with malignant cholestasis compared to that of choledocholithiasis. methods: ...

background: management of multiple sclerosis (ms) is based on the usage of immunosuppressive and immune-modulating medications. cytokines play an important role in the pathogenesis of ms. objective: to evaluate the effects of rapamycin on the concentrations of th1/th2/th17 serum cytokines in patients with ms. methods: six patients with relapsing remitting ms as a case group and 6 healthy indivi...

Tree damage from a variety of types wind events is widespread and great ecological economic importance. In terms areas impacted, tropical storms have the most effects on temperate forests, with southeastern U.S. forests particularly prone to storm damage. This impact motivates attempts understand tree forest characteristics that influence levels study presents initial findings spatially explici...
