Dariush Ranjbar Vakilabadi,Sina Dobaradaran,Tahereh Kazemi Vakilabady,Rahim Tahmasbi
Journal of Fasa University of Medical Sciences , 2012,
Abstract: Background and Objective: Road transportation and specifically bus travel accounts for the bulk of travel. Contaminated drinking water consumption is one of the issues that threaten health, and always there is pollution possibility in drinking water in buses. This study evaluated the microbial quality of consumed drinking water in buses and also compared it with available standards. Materials and Methods: This study is a cross-sectional study. By considering similar studies, 95% confidence interval and based on the samples size formula for tradition of proportion, 80 buses from 122 buses that entered Bushehr Passenger Depot from other cities or exited it were randomly selected. Over a three-month period, samples were taken from drinking water in these buses. Temperature, pH, residual chlorine, total coliform (TC), and fecal coliform (E. coli) in each sample were measured in accordance with the standard method. Statistical analysis of the data was carried out with SPSS Version 16, and the t-test was performed for statistical difference. Results: The results showed that residual chlorine in 97.5% was zero and pH values of the samples were in the range of 6.8-8.7. TC and E. coli numbers in 12.5% and 8.8% of the samples were higher than those of standards, respectively. Conclusion: Use of ice, washing time of the drinking water tank (daily or weekly), and method of usage and storage of drinking water (with 20-liter tanks) had significant effects on the bacterial loads of the drinking water in the tanks (p value <0.05). Some factors such as tank material, driver's education and age, type and model of the bus, filling time of the tank (daily or weekly), the method of filling and emptying the tank (complete clearing out of the tank or otherwise), and distance had no significant effect on the quality of the drinking water in the buses.
Non-Diapiric Salt Domes in the West Zanjan, Central Iran  [PDF]
Sina Alizadeh
Open Journal of Geology (OJG) , 2017, DOI: 10.4236/ojg.2017.72009
Abstract: The salt domes of the west Zanjan (Central Iran) are the most important structures in the study area. They have been formed by the uplifting and erosion together under low humidity and dry and warm climate condition. The salt rocks with near to 200 meters thickness are related to lower member of the Upper Red Formation (Early Miocene) that deposited in the inverted back arc basin. They have been formed in the Central Iran basin after the Arabian-Eurasian convergence. Based on filed works and preparation of geologic map, salt domes have been cropped out during regional uplifting and erosion along hinge zone of a longitudinal anticline. Also, there is no evidence for salt diapirism and so, they are different from some salt diapirs in the southwestern margin of Zanjan that is investigated by other researchers.

Sina Salamatpoor, Siavash Salamatpoor
Open Journal of Civil Engineering (OJCE) , 2014, DOI: 10.4236/ojce.2014.43016
Abstract:

An experimental study is carried out to investigate the static liquefaction of sand. For this purpose, Babolsar sand with its liquefiable parameters such as soil properties and high seismic level of underground water are investigated using static compression drained and un-drained tri-axial tests under isotropically and anisotropically conditions. Also, the data results of this sand are compared with those of the previous studies on soil case history. The study results indicate that Babolsar sand can experience the whole possible states of liquefaction soil, i.e. flow failure, limited and dilation behavior.

Hadi Ghadimi, Sina Nematizadeh
Modern Economy (ME) , 2016, DOI: 10.4236/me.2016.74046
Abstract: Studying the process of annual balance sheets, interests and losses of Iran Zamin Bank in relation to other banks has a low share. Thus, the rise of guidelines in editing framework of strategic plan is necessary in this bank. The study analyzes the strategic plan of Iran Zamin Bank. It also analyzes the financial implications in balanced score card through the relationship among profitability, productivity and financial growth. We introduced two indexes for productivity. The results are as follows. There’s not any negative and significant relationship between the capitation of profit index and capitation index in terms of administrative costs comparing all costs. There’s a positive and significant relationship between the financial implication indexes and profitability index. There’s a significant and negative relationship between productivity indexes and financial growth index. Therefore, the effect of strategic plan can be evaluated by using the available tools and the organization’s performance can be assessed.
Spatial Knowledge Acquisition in the Process of Navigation: A Review  [PDF]
Negar Ahmadpoor, Sina Shahab
Current Urban Studies (CUS) , 2019, DOI: 10.4236/cus.2019.71001
Abstract: Spatial cognition has become an increasingly important area of study since it represents a major type of human knowledge with considerable practical significance. The general assumption is that people’s spatial knowledge forms people’s spatial behaviour, such as navigation, in the environment. However, there are some critical issues within this area, including: how such knowledge is represented and organised, the mechanisms by which it is activated, and the elementary and higher-level cognitive processes that function upon the knowledge base to produce new knowledge as well as the factors that are influential on acquiring spatial knowledge. The theories regarding spatial knowledge acquisitions have attempted to address these issues. This paper discusses these issues by reviewing the literature. As such, the paper firstly provides the research background on spatial knowledge acquisition and the theories of spatial knowledge development. Secondly, the paper debates the main factors affecting acquiring and forming knowledge about the environment. In doing that, the effects of two main factors are discussed: 1) the means of spatial knowledge acquisition (direct experience, physical map, and mobile maps), and 2) the role of different properties of physical environment.
Scalable Cavity Quantum Electrodynamics System for Quantum Computing  [PDF]
Mohammad Hasan Aram, Sina Khorasani
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.611151
Abstract: We introduce a new scalable cavity quantum electrodynamics platform which can be used for quantum computing. This system is composed of coupled photonic crystal (PC) cavities which their modes lie on a Dirac cone in the whole super crystal band structure. Quantum information is stored in quantum dots that are positioned inside the cavities. We show if there is just one quantum dot in the system, energy as photon is exchanged between the quantum dot and the Dirac modes sinusoidally. Meanwhile the quantum dot becomes entangled with Dirac modes. If we insert more quantum dots into the system, they also become entangled with each other.
Half Rate Quasi Cyclic Low Density Parity Check Codes Based on Combinatorial Designs  [PDF]
Sina Vafi, Narges Rezvani Majid
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.412002
Abstract: This paper presents new half rate Quasi Cyclic Low Density Parity Check (QC- LDPC) codes formed on the basis of combinatorial designs. In these codes, circulant matrices of the parity check matrix are formed on the basis of subsets in which the difference between any two elements of a subset is unique with all differences obtained from the same or different subsets. This structure of circulant matrices guarantees non-existence of cycle-4 in the Tanner graph of QC-LDPC codes. First, an irregular code with girth 6 constituted by two rows of circulant matrices is proposed. Then, more criteria will be considered on the structure of subsets with the mentioned feature aiming to represent a new scheme of regular QC-LPDC codes with girth at least 8. From simulations, it is confirmed that codes have similar to or better performance than other well-known half rate codes, while require lower complexity in their design.
The relevance of ligament balancing in total knee arthroplasty: how important is it? A systematic review of the literature
Sina Babazadeh
Orthopedic Reviews , 2009, DOI: 10.4081/or.2009.e26
Abstract: Ligament balancing affects many of the postoperative criteria for a successful knee replacement. A balanced knee contributes to improved alignment and stability. Ligament balancing helps reduce wear and loosening of the joint. A patient with a balanced knee is more likely to have increased range of motion and proprioception, and decreased pain. All these factors help minimize the need for revision surgery. Complications associated with ligament balancing can include instability caused by over-balancing and the possibility of neurovascular damage during or as a result of ligament balancing. This article attempts to summarize the literature, to define a balanced knee, and outline the benefits and possible complications of ligament balancing. Different techniques, sequences, and tools used in ligament balancing, and their relevance in correcting various deformities are reviewed.
Exploring the significant role of meta-discourse in academic writing for a discourse community by academic members
Nasiri, Sina
International Journal of Research Studies in Education , 2013,
Abstract: Academic writing is kind of writing in which the writers of an academic community try to inform their colleagues about their findings. When they want to write for their communities they should know how to write for. This issue can be outlined by recognizing the underlying features of a particular community and discipline. Recognizing the features is possible through the phenomenon called Meta-discourse. Meta-discourse refers to the aspects of text structure which goes beyond the subject matter and shows the presence of the author, involves linguistic elements which writers use to contribute the acceptability and understandability of the content of the text. Considering the important role of meta-discourse in academic writing, this descriptive study attempts to discover the meaning of meta-discourse and its two main categories, i.e. textual meta-discourse and interpersonal meta-discourse, based on the taxonomy developed by Hyland (1998a). Finally the researcher proposes some of the main issues relating the presence of meta-discourse in texts.
"The Tube is Flickering Now": Aesthetics of Authenticity in Good Night, and Good Luck
Nitzsche, Sina
COPAS : Current Objectives of Postgraduate American Studies , 2007,
Abstract: The article examines the Clooney/Heslov/Soderbergh production Good Night, and Good Luck (2005). Its unusual visual style (cinematography, mise-en-scène, etc.) enables an immediate aesthetic viewing experience of Cold War America. Drawing on Fluck's discussion about aesthetics and its socio-cultural function, the "docu-drama" (Doherty 53), while referring to the era of McCarthyism, serves as an instance of articulation for the dissatisfaction with contemporary American politics.
