Authors: Heidari Fatemeh , Shariatmadari Zeinab , Riahi Hossein 
Published: December 2018

Background:
Microalgae are the source of various compounds with high potentials for being
used in different industries. The production of such compounds can be raised under extreme conditions.
In the present study, four cyanobacteria and one coccoid green alga were examined which were isolated
from hot springs in high background radiation areas in Ramsar, a city in the north of Iran.

Methods:
Cadmium adsorption from aqueous solution, response towards cadmium stress, antioxidant
activity, total phenolic compound and drought tolerance were investigated in these microalgae.

Results:
The results showed that these extremophile microalgae contain valuable biological compounds
which can be useful in remediation of heavy metals from contaminated water and soils and pharmaceutical
applications. The unicellular cyanobacterium, Chroococidiopsis thermalis IBRC-M50002, was the
best strain with the highest biological activity in various testes such as cadmium adsorption (225 mg
g-1), cadmium tolerance stress (100 mg ml-1), antioxidant activity (IC50= 18 μg mg-1) and total phenol content
(100 μg ml-1). The coccoid green algae Grasiella emersonii IBRC-M50001, also exhibited significant
antioxidant activity (IC50=10 μg mg-1) and total phenol compound (116 μg ml-1), but its cadmium adsorption,
tolerance at cadmium stress and desiccation were lower than Chroococidiopsis thermalis.

Conclusion:
HBRAs microalgae, isolated from extreme conditions, are useful microorganisms for the
production of bioactive substances and natural antioxidants. In other words, they exhibited high capacity
to be used in pharmaceutical, industrial and commercial applications.

Authors: Nasser Mai , Hazem Noha M. , Atwa Amany , Baiomy Amina 
Published: December 2018

Background:
Rheumatoid Arthritis (RA) is an autoimmune, chronic, and systematic
disease. It affects joints and bones. The exact etiology of RA is still unclear. Varied genetic
and environmental factors have been associated with the increased risk for RA. Overactivation
of Toll-Like Receptors (TLRs) could initiate the development of autoimmune diseases
including RA.

Objective:
The aim of the study was to evaluate TLR2 gene expression in rheumatoid arthritis
patients and investigate its correlation with the disease activity.

Materials and Methods:
This study included 60 patients and 20 healthy individuals. The patients
were diagnosed with RA according to the 2010 American College of Rheumatology/
European League Against Rheumatism criteria (ACR/EULAR). All included subjects
did not have any joint disorders and /or autoimmune diseases. RA disease activity was determined
by the disease activity score of 28 joints. Whole blood was collected from all participants.
Total RNA extraction was done. TLR2 mRNA expression was assessed by reverse
transcription-PCR (RT-PCR).

Results:
TLR2 mRNA expression was found to be significantly higher in RA patients compared
to healthy controls. Also, a strong positive correlation was found between TLR2 expression
level and the disease activity score. A non significant positive correlation was found
between TLR2 expression and serum Rheumatoid Factor (RF) level.

Conclusion:
TLR2 pathway may have an important role in RA pathogenesis and could be a
new biomarker for diagnosis and monitoring disease activity.
Feature Selection for Histopathological Image Classification using levy Flight Salp Swarm Optimizer
Authors: Rachapudi Venubabu , Devi Golagani Lavanya 
Published: December 2018

Background:An efficient feature selection method for Histopathological image classification plays an important role to eliminate irrelevant and redundant features. Therefore, this paper proposes a new levy flight salp swarm optimizer based feature selection method.Methods:The proposed levy flight salp swarm optimizer based feature selection method uses the levy flight steps for each follower salp to deviate them from local optima. The best solution returns the relevant and non-redundant features, which are fed to different classifiers for efficient and robust image classification.Results:The efficiency of the proposed levy flight salp swarm optimizer has been verified on 20 benchmark functions. The anticipated scheme beats the other considered meta-heuristic approaches. Furthermore, the anticipated feature selection method has shown better reduction in SURF features than other considered methods and performed well for histopathological image classification.Conclusion:This paper proposes an efficient levy flight salp Swarm Optimizer by modifying the step size of follower salp. The proposed modification reduces the chances of sticking into local optima. Furthermore, levy flight salp Swarm Optimizer has been utilized in the selection of optimum features from SURF features for the histopathological image classification. The simulation results validate that proposed method provides optimal values and high classification performance in comparison to other methods.

Authors: Khamparia Aditya , Singh Sanjay K. , Luhach Ashish K. 
Published: December 2018

Objective:
The blended fusion of Support Vector Machine (SVM) and Principal Component Analysis (PCA) have been widely used in recognizing handwritten digit characters of Devanagari script. The feature information from the character is extracted using its skeleton structure which optimally reduce data dimensionality using PCA. There is ample information available on handwritten charac-ter recognition on Indian and Non-Indian scripts but very few article emphasized on recognition of Devanagari scripts. Therefore, this paper presents an efficient handwritten Devanagari character recognition system based on block based feature extraction and PCA-SVM classifier.

Methods:
We have collected samples of handwritten Devanagari characters from different handwritten experts for classification.

Results:
For experimental work, total of 100 images having Devanagari digit characters been used for the purpose of training and testing. The proposed system achieves a maximum recognition accuracy of 96.6 % and 96.5% for 5 & 10 fold validations with 70% training and 30% testing data using block based feature and SVM classifier having different kernels.

Conclusion:
The obtained results achieve maximum accuracy using SVM classifier for digit character recognition. In future deep learning networks will be considered for accuracy enhancement and precision.
Multi-AUV Aided Cooperative 3D-localization for Underwater Sensor Networks
Authors: Zhang Meiyan , Cai Wenyu 
Published: December 2018

Background:
Effective 3D-localization in mobile underwater sensor networks is still an
active research topic. Due to the sparse characteristic of underwater sensor networks, AUVs (Autonomous
Underwater Vehicles) with precise positioning abilities will benefit cooperative localization.
It has important significance to study accurate localization methods.

Methods:
In this paper, a cooperative and distributed 3D-localization algorithm for sparse underwater
sensor networks is proposed. The proposed algorithm combines with the advantages of both recursive
location estimation of reference nodes and the outstanding self-positioning ability of mobile
AUV. Moreover, our design utilizes MMSE (Minimum Mean Squared Error) based recursive location
estimation method in 2D horizontal plane projected from 3D region and then revises positions
of un-localized sensor nodes through multiple measurements of Time of Arrival (ToA) with mobile
AUVs.

Results:
Simulation results verify that the proposed cooperative 3D-localization scheme can improve
performance in terms of localization coverage ratio, average localization error and localization
confidence level.

Conclusion:
The research can improve localization accuracy and coverage ratio for whole underwater
sensor networks.

Published: December 2018

Â Acute Coronary Syndrome (ACS) is a group of symptoms that are classify as unstable angina (ATS), ST-Segment Elevation Myocardial Infarction (STEMI) and non ST-Segment Elevation Myocardial Infarction (NSTEMI). Main objective to provide timely reperfusion therapy is essential to improve survival. Initial and rapid intervention after the occurrence of coronary artery disease is associated with better clinical outcomes, but it is hampered by the nature of the patient's seeking decisions Patients expect the type of heart attack they often see in medical movies and television: like chest pain that grips and causes it to fall to the floor. This study aims to analyze the chest discomfort experienced by patients associated with delay in reperfusion therapy of Acute Coronary Syndrome. The method used is observational analytic with cross sectional approach. Nonprobability sampling with time quota technique obtained sample of 60 respondents. The results obtained as many as 55% of patients come more than 120 minutes after the onset of discomfort in the chest. The patient's delay in coming to the associated hospital is an accompanying symptom factor at onset with p = 0.048, and OR = 4.596 (1.014-20.828). There were no significant differences in the scores of knowledge, behavior, and beliefs based on the ACS response index between patients who came <120 minutes and> 120 minutes. The conclusions of this study present the accompanying symptom presentations at onset with the time interval between the appearances of the SKA symptoms until arriving at the IGD door. Seeing the results of this study suggests the need for efforts from medical staff to optimize the interpretation of "chest pain characteristics" to patients and families or who are susceptible about specific and non-specific cardiac signs.Â Keywords: acute coronary syndrome, prehospital delay, onset to door, reperfusion

Authors: Muhammed Akram Ahmed 
Published: December 2018

Abstract
The aim of this study is to find a new method of budgeting in one of the most important state facilities, namely, government universities, specifically the University of Garmian, by preparing the performance budget using the ABC method to achieve the efficiency and effectiveness of limited resources. The budget used in public universities is budget balancing. It is a traditional budget that focuses on the adoption of inputs without attention or focus on the objectives or the measurement of the outputs and the resulting effects, which weakens the accountability approach to efficiency and efficiency in implementation. In order to achieve the objectives of this study, a thorough analysis and discussion of the scientific elements related to the fundamentals of the proposed budget was carried out. It was concluded that the performance budget through the use of the ABC system may lead to the effective completion of programs and activities at the University and other government universities. Extent of response to planned programs and objectives.
An Examination of Factors Driving Big 4 Audit Fee Premiums: Evidence from India's Audit Market
Authors: Jacob Joshy , Desai Naman , Agarwalla Sobhesh Kumar 
Published: December 2018

SYNOPSIS
This study examines fee premiums earned by Big 4 auditors in India and identifies the primary reason for such fee premiums. There are three primary drivers of Big 4 fee premiums. Big 4 auditors charge a fee premium for their reputation, for providing a superior quality of audit, and for indemnifying losses for a company's stakeholders. Since the risk of auditor litigation in India is relatively low, Big 4 premiums in India would not be driven by the need for auditors to indemnify losses. The results indicate that Big 4 auditors earn significantly higher fees in India and also that their clients enjoy significantly higher earnings response coefficients compared to non-Big 4 clients. However, there is no difference in the quality of audit provided by Big 4 and non-Big 4 auditors as measured by the magnitude of reported discretionary accruals.
