Abstract: This experiment was conducted to study effect of poly germander (Teucrium polium) and watercress (Nasturtium officinale) extracts on performance and serum biochemistryl of broilers. Two hundred and forty male Ross broilers (were alloted into 4 diet treatments for 42 days. The birds were fed their standard feed without any addition (control) or with addition of 200 ppm of poly germander extract (T1), 200 ppm watercress extract (T2) or 200 ppm of the combination of both components (T4). No significant change was observed in term of growth parameters and blood biochemistry, however, abdominal fat decreased significantly in the watercress and the combination extracts supplemented groups. The study highlighted the potential of these herbal extracts to improve body performance and carcass quality of broilers.
Optimal Node Scheduling for Desired Percentage of Coverage in Wireless Sensor Networks  [PDF]
Hamid Khosravi
Wireless Sensor Network (WSN) , 2012, DOI: 10.4236/wsn.2012.45018
Abstract: Recent developments in wireless communication and embedded computing technologies have led to the advent of wireless sensor network technology. Hundreds of thousands of these micro sensors can be deployed in many areas including health, environment and battlefield in order to monitor the domain with desired level of accuracy. When wireless sensors are deployed in an area, the lifetime of the network should last as long as possible according to the original amount of energy. Therefore, reducing energy consumption in WSNs is of primary concern. We have proposed a node scheduling solution that solves the coverage and connectivity problem in sensor networks in an integrated manner. In this way we will divide network life time to finite number of rounds and in each round we will generate a coverage bitmap of sensors of the domain and based on this bitmap it will decided which sensors remain active or go to sleep. We will check the connection of the sensor network by using Laplacian of adjancy graph of active nodes in each round. Also the network will be capable of producing desired percentage of coverage by using coverage bitmap. We will define the connected coverage problem as an optimization problem and we will seek a solution for the problem by using Genetic Algorithm optimization method.

Advances in Aging Research (AAR) , 2015, DOI: 10.4236/aar.2015.41002
Abstract: Although risk factors of Ischemic Heart Disease (IHD) are well known, knowledge about the distribution of these risk factors in different subgroups of patients can be used for designing preventive programs. The aim of this study was to assess differences of prevalence of IHD risk factors in elderly and non-elderly patients in their first Acute Myocardial Infarction (AMI). In this retros-pective study, elderly (age > 65; n = 1060) and non-elderly (age ≤ 65; n = 2228) patients with first AMI who were admitted into four teaching hospitals in Tehran between 1982 and 2005 were recruited. Risk factors containing male gender, systolic and diastolic hypertension (HTN), diabetes, hypertriglyceridemia, hypercholesterolemia, smoking and family history of IHD were compared between the two groups. Among different risk factors, diabetes and systolic HTN were more common in elderly than their non-elderly counterparts, and male gender, smoking, family history of IHD and dyslipidemia were more common in non-elderly patients than elderly ones (p < 0.05 for all comparison). Diastolic HTN showed no significant difference between the two groups. Findings of this study, stating difference of prevalence of risk factors in two elderly and non-elderly groups, can be used by health policy makers to conduct preventive programs for AMI in this country.
Design of 1.33 μm and 1.55 μm Wavelengths Quantum Cascade Photodetector  [PDF]
S. Khosravi, A. Rostami
Optics and Photonics Journal (OPJ) , 2017, DOI: 10.4236/opj.2017.78B016
In this paper, a quantum cascade photodetector based on intersubband transitions in quantum wells with ability of detecting 1.33 μm and 1.55 μm wavelengths in two individual current paths is introduced. Multi quantum wells structures based on III-Nitride materials due to their large band gaps are used. In order to calculate the photodetector parameters, wave functions and energy levels are obtained by solving 1-D Schrodinger–Poisson equation self consistently at 80 ?K. Responsivity values are about 22 mA/W and 18.75 mA/W for detecting of 1.33 μm and 1.55 μm wavelengths, respectively. Detectivity values are calculated as 1.17 × 107 (Jones) and 2.41 × 107 (Jones) at wavelengths of 1.33 μm and 1.55 μm wavelengths, respectively.

Groups with the same orders of Sylow normalizers as the Mathieu groups
Behrooz Khosravi,Behnam Khosravi
International Journal of Mathematics and Mathematical Sciences , 2005, DOI: 10.1155/ijmms.2005.1449
Abstract: There exist many characterizations for the sporadic simple groups. In this paper we give two new characterizations for the Mathieu sporadic groups. Let M be a Mathieu group and let p be the greatest prime divisor of |M|. In this paper, we prove that M is uniquely determined by |M| and |NM(P)|, where P∈Sylp(M). Also we prove that if G is a finite group, then G≅M if and only if for every prime q, |NM(Q)|=|NG(Q′)|, where Q∈Sylq(M) and Q′∈Sylq(G).
Frames and bases in tensor products of Hilbert spaces and Hilbert C*-modules
Amir Khosravi,Behrooz Khosravi
Mathematics , 2007,
Abstract: In this article, we study tensor product of Hilbert $C^*$-modules and Hilbert spaces. We show that if $E$ is a Hilbert $A$-module and $F$ is a Hilbert $B$-module, then tensor product of frames (orthonormal bases) for $E$ and $F$ produce frames (orthonormal bases) for Hilbert $A\otimes B$-module $E\otimes F$, and we get more results. For Hilbert spaces $H$ and $K$, we study tensor product of frames of subspaces for $H$ and $K$, tensor product of resolutions of the identities of $H$ and $K$, and tensor product of frame representations for $H$ and $K$.
Theories of Equity in Health Care, Implications for Developed and Developing Countries
AR Olyaee Manesh
Iranian Journal of Public Health , 2005,
Abstract: Objective: This abstract focuses on theoretical background for the notion of “equity in health care” and on the implications of applying these theories to the health care of developed and developing countries. Equity Principals and the Implications: There are different theories about the principle of Equity or Justice such as Altruism, Utilitarians, Marxists, Rawls’ theory and Nazick’s entitlement. Among these theories, some of them are applicable to health care such as Libertarianism and Egalitarianism. The focus of the Libertarians is on the extent to which people are free to purchase the health care that they want. The Libertarians’ principle is the main equity base for private health systems. In contrast, Egalitarians suggest that finance of the health care should be according to the ability to pay and distribution of health care should be according to the need (ill health). It seems that policy makers in most developed countries such as European countries accept the Egalitarians’ principle and application of this equity principle by their health systems has significantly reduced health inequities and inequalities in these countries. There are a limited number of studies to look at equity in the health care of developing countries. A common equity principle for these countries is “equal access for everyone” and different mechanisms are applied to attain this target. Despite the overall improvements in health care in recent years, evidence indicates that many of developing countries have failed to provide equal access to health care for all in need. The financial limitations of the governments, spending about 70% of the health care resources on hospital-based care, unequal access to hospital services in favour of urban population, income inequalities among population, and lack of consistent and up-to-date information of inequalities, make developing countries unable to monitor and prevent inequities and inequalities of health care. Conclusion: The main equity principle in the health care of developed countries is Egalitarians’ principle in which, health care should be financed according to ability to pay and should be delivered according to the need. Applying the equity principals to the health care of developed countries has deeply promoted equitable health care in these countries. There are a limited number of studies about this issue in developing countries. A common equity target in these countries is “equal access for everyone in need” which is close to the Egalitarians’ point of view. However, some factors have hampered these countries’ attempt
A Method of Detecting Sql Injection Attack to Secure Web Applications
Sruthy Manmadhan,Manesh T
International Journal of Distributed and Parallel Systems , 2012,
Abstract: Web applications are becoming an important part of our daily life. So attacks against them also increasesrapidly. Of these attacks, a major role is held by SQL injection attacks (SQLIA). This paper proposes anew method for preventing SQL injection attacks in JSP web applications. The basic idea is to checkbefore execution, the intended structure of the SQL query. For this we use semantic comparison. Ourfocus is on stored procedure attack in which query will be formed within the database itself and sodifficult to extract that query structure for validation. Also this attack is less considered in the literature.

M Jamshidi Manesh
Qom University of Medical Sciences Journal , 2012,
Abstract: Background and Objectives: The meaning of menopause and women experience of this transitional stage are related to cultural norms, social factors and one's knowledge of menopause. Women’s image of menopasuse affects self-care and follow-ups during this stage. Among them is consideration of sexuality which is often ignored. The aim of this study was to discover menopausal complications in Iranian women. Methods: 14 women in menopausal stage were interviewed about their clinical experience. The interviews were transcribed and then analyzed using Van Manen’s phenomenology technique. Result: Data analysis showed that one of the women's most important clinical experiences of menopause which they can deliberately express was the start of a new stage. Since, according to those women, changes in their life style were being made in comparison with earlier stages, one of the most important problems that escaped unobserved was sexual challenges which started at this stage. Conclusion: The findings this study reveal women's beliefs about their sex life. This can be used as a basis for education and offering guidelines in order to increase their quality of life.
