Optimal Two-Tier Forecasting Power Generation Model in Smart Grids
Kianoosh G. Boroojeni,Shekoufeh Mokhtari,M. H. Amini,S. S. Iyengar
Computer Science , 2015,
Abstract: There has been an increasing trend in the electric power system from a centralized generation-driven grid to a more reliable, environmental friendly, and customer-driven grid. One of the most important issues which the designers of smart grids need to deal with is to forecast the fluctuations of power demand and generation in order to make the power system facilities more flexible to the variable nature of renewable power resources and demand-side. This paper proposes a novel two-tier scheme for forecasting the power demand and generation in a general residential electrical gird which uses the distributed renewable resources as the primary energy resource. The proposed forecasting scheme has two tiers: long-term demand/generation forecaster which is based on Maximum-Likelihood Estimator (MLE) and real-time demand/generation forecaster which is based on Auto-Regressive Integrated Moving-Average (ARIMA) model. The paper also shows that how bulk generation improves the adequacy of proposed residential system by canceling-out the forecasters estimation errors which are in the form of Gaussian White noises.

Fracture resistance of endodontically treated teeth restored by different FRC posts: An in vitro study
Torabi Kianoosh,Fattahi Farnaz
Indian Journal of Dental Research , 2009,
Abstract: Background: Posts and cores are often required for restoration of pulpless teeth and to provide retention and resistance for a complete crown, but conventional posts may increase the root fracture. Objective: This study was performed to compare the root fracture resistance of extracted teeth treated with different fibers reinforced with composite posts and treated teeth with conventional post and core systems. Materials and Methods: Root canal therapy was performed for 50 mandibular first premolars. The coronal portion of each tooth was amputated, and five post and core systems (cast, polyethylene woven, glass, carbon, and quartz fiber posts) were compared. Acrylic resin blocks were used for mounting, using a layer of elastomeric impression material covering the roots. The load was applied axially and measured with a universal testing machine. Results and Conclusion: Significantly, cast posts and cores had a higher failure threshold including teeth fracture; whereas, fiber posts failure was due to core fracture, with or without fractures in coronal portion of posts. Difference in FRC posts did not provide any significant difference in the load failure and the mode of fracture.
Application of L-moment Theory in Flood Frequency Analysis of Central Catchments of Iran
S. S. Eslamian,S. Chavoshi Boroojeni
Journal of Science and Technology of Agriculture and Natural Resources , 2003,
Abstract: Numerous methods are used in the investigation of floods in catchments such as regional flood frequency analysis. Regional flood frequency analysis relies on physical, climatic and ecological characteristics of catchments and applies statistical methods to study flow records. Hosking and Wallis developed Probability Weighted Moments and presented L-moments statistics as a new tool for flood frequency analysis. In this paper, the theory of L-moments was used to study the flood frequency of central catchments of Iran. A number of 27 sites each with more than 5 years of observed data were studied. In the first step, the diagram of L-kurtosis versus L-skewness was used and proper distributions for each site were applied. In order to eliminate the heterogeneous sites, homogeneous tests based on D, H1, H2 and H3 criteria were performed indicating that two sites appeared to be heterogenous. Next, using Goodness of Fit Test, the best regional distributions were determined which are GL, GEV, GN, PE3 and GPA, respectively. Finally, quantile estimates for distributions accepted at a 90% level were presented.
Myocardial Infarction in a Patient with Prosthetic Aortic Valve

Journal of Tehran University Heart Center , 2006,
Abstract: A 45- year old man with a history of Aortic Valve replacement presented with acute chest pain which was diagnosed to be anterior wall myocardial infarction. He received thrombolytic therapy with streptokinase. Echocardiography and fluoroscopy showed normally functioning ball and cage aortic prosthesis. Coronary arteriography showed globular filling defect in midportion of left anterior descending coronary artery, most probably embolized thrombus. The patient underwent medical treatment especially warfarin with higher range of INR without any intervention. He had a smooth in-hospital course and uneventful recovery.

In vitro and in vivo interaction of oral contraceptive high dose (HD) with urine morphine diagnostic test
Valiollah Hajhashemi,Mohsen Minaiyan,Mahdi Saberian-Boroojeni
Physiology and Pharmacology , 2007,
Abstract: Introduction: Urine morphine test, in several countries is the most primarily available qualitative test for detecting opioid abusers. Since the users of illicit drugs attempt to defeat urine tests and there are also plenty of claims that usage of HD (high dose) contraceptive pills can result in false-negative results, we decided to design the present study to investigate the probable in vitro and in vivo interaction of HD contraceptives and urine morphine diagnostic test. Methods: Several high and low concentrations of ethinylestradiol (EE), levonorgestrel (LN), and both of them were made in the blank urine and urine samples obtained from morphine abusers and then were detected by Acon urine test strips. Also, high and low doses of EE, LN, and both of them were administered orally to separate groups of control, morphine dependent, and morphine treated (20 mg/kg in single dose, s.c.) male Wistar rats (225 ± 25 g). The urine samples were collected during 3-6, 12-15, 21-24 h time intervals in metabolic cages and were examined by Acon urine tests. Results: Neither contraceptive constituents nor their urine metabolites at different levels were able to negate the results of urine kits. Conclusion: We conclude that there is no interaction between HD contraceptives and urine morphine diagnostic tests both in vitro and in vivo. It is recommended to inform the results of this study to withhold further misusage of contraceptives and their possible adverse effects.
In silico design and expression of a novel fusion protein of HBHA and high antigenic region of FAP-P of Mycobacterium avium subsp. paratuberculosis in Pichia pastoris

Abstract: Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of Johne's disease in ruminants and there has been a shift in the public health approach to MAP and human diseases like Crohn's disease. The prevention of infection by MAP in ruminants is thought to deter the high impact of economic losses in the level of dairy industry and possible spreading of this pathogen in dairy products. The present study was done to investigate the construction and expression of the soluble form of a novel fusion protein, consisting of Heparin-binding hemagglutinin (HBHA) and high antigenic region of Fibronectin Attachment Protein-P (FAP-P), in order to introduce as a Th1 inducer subunit vaccine against MAP. HBHA is a mycobacterial adhesin and it has been demonstrated that a HBHA-specific IFN-γ response, in latent M. tuberculosis infection, depends on the methylation of the antigen. Further, FAP-P induces Th1 polarization. Because methylation of HBHA was not performed in E. coli, Pichia pastoris was chosen as the host. The desired fusion protein had a similar 3D structure to that of HBHA with its native form and post-translational methylation in C-terminal. Hence, the uptake of the purified fusion protein will be done by M cells because ofHBHA, and cell-mediated immunity will be induced because of both antigens. Eventually, successful construction and expression of the newly-designed chimeric protein under the mentioned conditions is reported in this article.
Ear Candling: A Dangerous Pleasure?
Kianoosh Nahid,Prepageran Narayanan,Mohammad Amin Jalaluddin
Iranian Journal of Otorhinolaryngology , 2011,
Abstract: Ear candling is an alternative medicine practice alleged to enhance general health by putting an end of a hollow candle in the ear canal and lighting up the other end of it. It also is advertised for cerumen and debris (bacteria and fungi) removal. Ear candling is claimed to create negative pressure for drawing cerumen from the ear and to benefit the ears in many ways. It is however not free of complications and is now banned. Here we would like to highlight potential complications to this.
