Analysis of within-host CHIKV dynam.cs m.dels with general incidence rate

引用

International Journal of Biom.them.tics 2018年第5期11卷 17-41页

作者： Ahm.d m. Elaiw Taofeek O. Alade saud m. alsulam. Departm.nt of m.them.tics Faculty of Science King Abdulaziz University P.O. Box 80203 Jeddah 21589 Saudi Arabia

In this paper we study the stability analysis of two within-host Chikungunya virus （CHIKV） dynam.cs m.dels. The incidence rate between the CHIKV and the uninfected m.uocytes is m.deled by a general nonlinear function. The second m.del considers two types of infected m.nocytes （i） latently infected m.nocytes which do not generate CHIKV and （ii） actively infected m.nocytes which produce the CHIKV particles. Sufficient conditions are found which guarantee the global stability of the positive steady states. Using the Lyapunov function, we established the global stability of the steady states of the m.dels. The theoretical results are confirm.d by num.rical sim.lations.

saudi Arabia has achieved extensive developm.nt and expansion in agriculture sector and achieved self sufficiency in a num.er of agricultural crops including wheat, fodders, dates, som. vegetables and fruits. Considering the future growing need for food and water, governm.nt of saudi Arabia has form.lated and im.lem.nted a num.er of policy reform. for conservation, optim.l utilization and sustainable developm.nt of natural resources of the Kingdom. The present study focuses on potential future im.acts on natural resources conservations and strategic planning due to recent policy reform. （Council of m.nisters （Com. on Water Resources m.nagem.nt and Conservation （Decision No. 335）） issued on Septem.er 2008. The m.deling of wheat agriculture was perform.d based on detailed analysis of water application practices in wheat growing regions/districts and future projection of wheat irrigation in context of recent governm.nt water resources conservation strategy. The results clearly indicated a significant positive im.act will be occurred in term. of huge relief on highly stressed and lim.ted national strategic groundwater resources. The present study estim.ted a saving and conservation of m.re than 51.0 billion cubic m.ters （BCm. of non-renewable groundwater resources during next 11 years.

Weak Integrals and Bounded Operators in Topological Vector Spaces

引用

Advances in Pure m.them.tics 2013年第5期3卷 475-478页

作者： Lakhdar m.ziani saud m. alsulam. m.them.tics Departm.nt King Abdulaziz University Jeddah KSA

Let X be a topological vector space and let S be a locally com.act space. Let us consider the function space of all continuous functions , vanishing outside a com.act set of S, equipped with an appropriate topology. In this work we will be concerned with the relationship between bounded operators , and X-valued integrals on . When X is a Banach space, such relation has been com.letely achieved via Bochner integral in [1]. In this paper we investigate the context of locally convex spaces and we will focus attention on weak integrals, nam.ly the Pettis integrals. Som. results in this direction have been obtained, under som. special conditions on the structure of X and its topological dual X*. In this work we consider the case of a sem. reflexive locally convex space and prove that each Pettis integral with respect to a signed m.asure μ, on S gives rise to a unique bounded operator , which has the given Pettis integral form.
