In the workplace, the arsenic is used in the semiconductor production and the manufacturing of pigments, glass, pesticides and fungicides. Therefore, workers may be exposed to airborne arsenic during its use in manufacturing. The purpose of this study was to evaluate the potential toxicity of particulate matters (PMs) doped with arsenic (PMs-Arsenic) using a rodent model and to compare the geno...
In parallel manipulator design, usual 6-DOF PMs, like the Stewart platform, suffer from the disadvantages of difficult forward kinematics, coupled motion, and small workspace, so that the motion planing and control become very complicated and difficult to be implemented in real application. Most of the PMs with lower mobility are over-constrained when assembly errors are considered [1]. Therefo...
Motivated by current trends in cloud computing, we study a version of the generalized assignment problem where a set of virtual processors has to be implemented by a set of identical processors. For literature consistency, we say that a set of virtual machines (VMs) is assigned to a set of physical machines (PMs). The optimization criteria is to minimize the power consumed by all the PMs. We te...
سابقه و هدف: ورود گونه های ماهی مهاجم دراکوسیستم های آبی، سبب بروز انواع اثرات منفی اکولوژیکی اقتصادی-اجتماعی می شود. اولین گام در تجزیه تحلیل مخاطرات ناشی از گونه غیربومی، شناسایی خطر است بر این اساس ابزارهای متعددی برای ارزیابی خطرات تهاجمی غیربومی به منظور پشتیبانی تصمیم گیرندگان گونه ها ایجاد شده است. هدف پژوهش قدرت تیلاپیای شکم قرمز (Coptodon zillii) حوضه آبریز تالاب شادگان (حوضه...
BACKGROUND Premenstrual syndrome (PMS) is one of major health problems in childbearing age women. Herein, we compared the nutritional status of vitamin D, calcium (Ca) and magnesium (Mg) in young students affected by PMS with those of normal participants. METHODS This study was conducted on 62 students aged 20‒25 yr in the city of Abadan (31 PMS cases and 31 controls). All participants comple...
Lx2-32c is a novel taxane derivative with a strong antitumor activity. In this study, we developed Lx2-32c-loaded polymeric micelles (Lx2-32c-PMs) with small size and investigated their antitumor efficacy against tumor growth and metastasis on 4T1 murine breast cancer cell line with Cremophor EL-based Lx2-32c solution as the control. In this study, copolymer monomethoxy polyethylene glycol2000-...
BACKGROUND Premenstrual syndrome (PMS) is reported by up to 85% of women of reproductive age. Although several studies have focused on the hormone and lipid profiles of females with PMS, the results are controversial. OBJECTIVES This study was designed to investigate the association of hormonal and metabolic factors with PMS among Iranian women of reproductive age. MATERIALS AND METHODS Thi...
The prevalence of hypertension is increasing among younger women, and new strategies are needed to identify high-risk women who should be targets for early intervention. Several mechanisms underlying hypertension might also contribute to premenstrual syndrome (PMS), but whether women with PMS have a higher risk of subsequently developing hypertension has not been assessed. We prospectively eval...
This paper reveals the relationship between the weighted Moore–Penrose generalized inverse and the force analysis of overconstrained parallel mechanisms (PMs), including redundantly actuated PMs and passive overconstrained PMs. The solution for the optimal distribution of the driving forces/torques of redundantly actuated PMs is derived in the form of a weighted Moore–Penrose inverse. Therefore...
