Asteroids provide fundamental clues to the formation and evolution of planetesimals. Collisional models based on the depletion of the primordial main belt of asteroids predict 10-15 craters >400 km should have formed on Ceres, the largest object between Mars and Jupiter, over the last 4.55 Gyr. Likewise, an extrapolation from the asteroid Vesta would require at least 6-7 such basins. However, C...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
As the climate changes, a growing demand exists to identify and manage spatial variation in crop yield ensure global food security. This study assesses soil variability its impact on maize under future eastern Kansas’ top ten maize-producing counties. A cropping system model, CERES-Maize of Decision Support System for Agrotechnology Transfer (DSSAT) was calibrated using observed yield. To accou...
Concerns have been raised on the effectiveness and sustainability of Soil Water Conservation (SWC) practices as adaptation options to climate change high intra– inter–annual rainfall variabilities in eastern Democratic Republic Congo (DRC). This study was conducted Ruzizi Plain, a dryland area, assess performance maize (Zea mays L.) under two Representative Concentration Pathways (RCP 4.5 8.5) ...
A coupled model of leaf photosynthesis and stomatal conductance as a function of photosynthetically active radiation (PAR), CO2, leaf temperature, relative humidity, and leaf age was calibrated for rose leaves. The photosynthetic parameters: maximum carboxylation rate (Vcmax), potential rate of electron transport (Jmax), rate of triose phosphate utilization (TPU), and leaf dark respiration rate...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
Climate change is a very serious threat to the agricultural sector and potentially brings new problems sustainability of production systems. This paper aims know how improve crop yield by changing nitrogen application ratio sowing time under future climate conditions based on CERES-Rice model. The model was calibrated validated with three-year field experiment (2018–2020), which coupled four N ...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
This study aims to assess the potential alterations in the hydrological regime attributed to projected climate change in one of the largest rivers in the Carpathian Area, the Mures River, and to estimate associated threats to riverine ecosystem. The eco-hydrological model, Soil and Water Integrated Model (SWIM), was applied on the Mures River basin, calibrated and validated against records at a...
