Examining Potential Travel Time Savings Benefits Due to Toll Rates That Vary by Lane  [PDF]
Negin Alemazkoor, Mark Burris
Journal of Transportation Technologies (JTTs) , 2014, DOI: 10.4236/jtts.2014.43024
Abstract:

By assigning different toll rates to different lanes during peak traffic hours, the demand for each lane of a road can be optimized. Lanes with lower travel times charge higher toll rates which are paid by those drivers who have higher values of travel time (VTT) and who want to avoid congestion in the other lanes. Conversely, travel time for those drivers with lower values of travel times will increase as they select the lower priced and slower lanes. This research examines toll rates that minimize the total value of travel time spent on the road under such a scenario. The optimum toll rates are dependent on the total road volume and distribution of VTT. The results show that total saved value of travel time can easily reach 11% of the total value of time spent traveling on the lanes when compared to a toll road with a uniform toll rate for all lanes. These savings vary based on many factors including the number of travelers on urgent trips.

Negin Bavili
Open Journal of Political Science (OJPS) , 2017, DOI: 10.4236/ojps.2017.73034
Abstract: In this paper,?how policy making can be affected by different political contexts will be studied. This study considers negative meaning load for the word populism and assumes populism as a communicative strategy that politicians use in order to get in touch with unrecognized sections of society. Populist Context with concentration on the role of people would help politicians manipulate mass of people and benefit welfare policies as means in attraction of people in order to achieve their goals. And comparison of welfare policies in?Iran after 1989 will clarify how Ahmedinejad’s populist policy making affected?Iran’s welfare.
Study of the EMC Effect for 27Al, 56Fe, 63Cu, and 107Ag Nuclei  [PDF]
Negin Sattary Nikkhoo, Farhad Zolfagharpour
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.311228
Abstract: In this paper the EMC effect for 27Al, 56Fe, 63Cu, and 107Ag nuclei are investigated with oscillator model. In this model has been assumed that nucleons in each level are affected by different mean field, so we use parameter having relation with radius of each level. Therefore; this assumption causes that extracted data for average binding energy =-22.48MeV, =-23.79MeV, =-29.56MeV, and =-31.25MeVare considered for 27Al, 56Fe, 63Cu, and 107Ag nuclei, respectively. Achieving results have agreement with experimental data.
Differential Cross Section of Electron Scattering From 3He and 3H Nuclei with Considering Pionic Contribution  [PDF]
Nazli Hamdolahi, Farhad Zolfagharpour, Negin Sattary Nikkhoo
World Journal of Nuclear Science and Technology (WJNST) , 2012, DOI: 10.4236/wjnst.2012.24022
Abstract: The excess pion inside the nucleus could change not only nucleons structure function, but also electron scattering cross section from nuclei. In this paper, we calculate pionic contribution in nuclear structure functions of 3He and 3H nuclei and the differential cross sections of electron scattering from these nuclei. At first, we calculate the Fermi motion and binding energy contribution as an important nuclear medium effect in scattering cross sections and then we add pionic contribution to structure functions and differential cross sections of electron scattering from these nuclei that the Fermi motion and binding energy are considered.
Synthesis and Characterization of New Biodegradable Chitosan/Polyvinyl Alcohol/Cellulose Nanocomposite  [PDF]
Alireza Samzadeh-Kermani, Negin Esfandiary
Advances in Nanoparticles (ANP) , 2016, DOI: 10.4236/anp.2016.51003
Abstract: In this report, a new nanocomposite based on chitosan/polyvinyl alcohol/nanocrystalline cellulose (Cts/PVA/NCC) was synthesized. The morphology and particle size of NCC and nanocomposites were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis and Fourier transform infrared (FT-IR) spectroscopy. According to XRD results, the size of NCC was found to be at the range of 15 - 17 nm. SEM images showed the rod-like shape of NCC whiskers. Finally, biodegradation and swelling studies were performed on Cts/PVA/NCC nanocomposites.
Prostaglandin-Induced Cystoid Macular Edema Following Routine Cataract Extraction
Negin Agange,Sameh Mosaed
Journal of Ophthalmology , 2010, DOI: 10.1155/2010/690707
Abstract: To our knowledge, we are reporting the first case of a 59-year-old man who developed recurrent CME with three separate trials of three different prostaglandin class drugs following uncomplicated phacoemulsification with intraocular lens implantation. Despite multiple reports of individual prostaglandin (PG) analogues being suggested as the cause of CME, there are no recommendations regarding withholding these medications in the perioperative period. Our patient first developed CME OD 4-months post uncomplicated cataract extraction. XALATAN (Latanoprost) had been restarted after surgery and discontinued at onset of CME. While off XALATAN (Latanoprost), the patient's CME resolved, but his IOP rose. The patient was started on LUMIGAN (Bimatoprost) to control the IOP, but within weeks his CME recurred. The patient's CME was again treated and his IOP remained acceptable, but then progressively increased. TRAVATAN (Travoprost) was attempted, but he presented with a third round of CME. Definitive conclusions about causal relationships cannot be made without well-designed, prospective clinical trials addressing this issue.
Artificial Reproduction of Octocoral (Plumarella flabellata)
Fariba Heidari and Negin Salamat*
Pakistan Veterinary Journal , 2012,
Abstract: The reproductive biology of Octocoral (Plumarella flabellata) in artificial habitats located in Northwest of Persian Gulf, Iran was studied by histological examination of gonad development. Various sizes of colonies were collected to determine the relationship between colony size and sexual maturity. The colonies smaller than 15 cm height did not contain gonads. Moreover, P. flabellata was a hermaphrodite species with gonads developed along with mesenteries. No planulae were observed in the samples investigated. Therefore, P. flabellata in Iran is most likely a broadcast spawener. The gonads were at the same developmental stages in each season. The results showed that spawning of P. flabellata probably occurred in July-August which is consistent with the suitable environmental conditions such as higher water temperature and long day-light. The present study indicated that P. flabellata exhibits a remarkably high reproductive potential, which contributes to its dominance in the artificial reef in Northwest of Persian Gulf.

Introduction The National Eye Institute estimates that there are 1.5 million surgeries for cataracts each year in the U.S. A common clinical scenario in a percentage of patients undergoing cataract extraction is receiving treatment for co-morbidities like glaucoma with hypotensive lipids. We report a case of a 59-year-old man who developed recurrent cystoid macular edema (CME) with three separate trials of prostaglandin analogs following uncomplicated phacoemulsification with intraocular lens implantation. Currently, we have no prospective, blinded-control trials to better define the ideal perioperative strategies in this patient population. 2. Case Report Our patient has a history of advanced pigmentary glaucoma in both eyes, which was controlled preoperatively for many years with XALATAN (Latanoprost), COSOPT (Timolol/Dorzolamide) fixed combination, and ALPHAGAN (Brimonidine) 0.1% purite OU. The patient developed visually significant cataracts in both eyes with visual acuity dropping below 20/40 OU prior to surgery. He had uncomplicated cataract extraction with IOL implant OD, followed one month later by OS. His best corrected visual acuity in each eye was 20/20 OU by one week post op. His immediate post-op regimen was AVELOX (Moxifloxacin) QID for one week, diclofenac QID for one month, and PRED FORTE (prednisolone) 1% QID for one week and then tapered off over the next three weeks. His XALATAN (Latanoprost) was resumed immediately
$(1-2u^2)$-constacyclic codes over $\mathbb{F}_p+u\mathbb{F}_p+u^2\mathbb{F}_p$

Mathematics , 2015,
Abstract: Let $\mathbb{F}_p$ be a finite field and $u$ be an indeterminate. This article studies $(1-2u^2)$-constacyclic codes over the ring $\mathbb{F}_p+u\mathbb{F}_p+u^2\mathbb{F}_p$, where $u^3=u$. We describe generator polynomials of this kind of codes and investigate the structural properties of these codes by a decomposition theorem.
Lepton Scattering Cross Section and Nuclear Structure Function of 4He and 12C Nuclei  [PDF]
Mir Hamid Musavi, Negin Sattary Nikkhoo, Farhad Zolfagharpour
World Journal of Nuclear Science and Technology (WJNST) , 2013, DOI: 10.4236/wjnst.2013.34022
Abstract:

This paper is an effort to extract the structure function, the EMC ratio, and the lepton scattering cross section in the convolution nuclear theory framework for 4He and 12C nuclei. We suppose that, in conventional approach, based on harmonic oscillator model, one could consider for a nucleus shell different hw parameters which are associated with the square root of the mean radius of the nucleus shells. We use GRV free nucleon structure function, which has good agreement with the proton and neutron structure function, extracted from experimental results. In addition, the lepton scattering cross sections of 4He and 12C nuclei are calculated in energy higher than 1 GeV. The extracted results show good agreement with experimental data.
