abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
background & aim: the aim of the study was to define the epidemiological characteristics of most important infectious diseases in iran in recent decades. methods & materials: this was a situation trend analysis of infectious diseases (vector and water borne disease, and food borne diseases) in recent decades based on data availability. three significance levels were used for mann-kendall test (...
mosquito borne infectious diseases are among important group of diseases worldwide. vaccination is available for some tropical mosquito-borne diseases, especially for japa-nese encephalitis virus infection and yellow fever. there are also several attempts to develop new vaccines for the other mosquito-borne diseases such as malaria, dengue infection and west nile virus infection. in this articl...
Anemia of chronic diseases (ACD) is a common problem in patients with infectious diseases and can influence the quality of life and patients' survival. Despite the clinical importance of ACD, data are still lacking regarding this problem in the infectious diseases. This study aimed to evaluate the prevalence, related factors, outcome and approaches to anemia in the infectious diseases ward. Thi...
A brief description of the importance of communicable diseases in history and the development of mathematical modelling of disease transmission is given. This includes reasons for mathematical modelling, the history of mathematical modelling from the foundations laid in the late nineteenth century to the present, some of the accomplishments of mathematical modelling, and some challenges for the...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
UNLABELLED Practical significance of understanding the dynamics and evolution of infectious diseases increases continuously in contemporary world. The mathematical study of the dynamics of infectious diseases has a long history. AIM By incorporating statistical methods and computer-based simulations in dynamic epidemiological models, it could be possible for modeling methods and theoretical a...
Since mathematical models play a key role in investigating the dynamics of infectious diseases, many for these diseases are developed. In this paper, it is aimed to determine Tuberculosis (TB) Turkey, how much will affect future and impact vaccine therapy on disease. For purpose, three (SIR, SEIR BSEIR) literature considered case Turkey. The model parameters obtained with TB reported data from ...
This is a theoretical study of the SIR model — popular mathematical propagation infectious diseases. We construct solution Cauchy problem for system two ordinary differential equations describing in integral form concentration dynamics infected and recovered individuals an immune population. A qualitative analysis carried out stationary states using Lyapunov function. An expression obtained coo...
