Abstract: The nutrient composition and sensory properties of
poultry-based patties (PBPs) incorporated with various levels of grey
oyster mushroom (Pleurotus sajor-caju, PSC) were studied. The
PBPs were formulated with either 0%, 25% or 50% of fresh ground
PSC. Results show poultry patty formulated with 25% PSC had
protein content of 17.46% lower than the control patty which had
18.13% but it was not significant. Meanwhile, both cooked poultry
patties containing 25% and 50% PSC significantly recorded lower
concentration of fat at 10.67% and 7.15%, respectively. On the other
hand, poultry patty added with 50% ground PSC shows the highest
concentration of total dietary fibre (TDF) of 4.90 g/100g compared to
poultry patty containing 25% of mushroom (3.40 g/100g) and to the
control (1.90g/100g). In addition, patty incorporated with 25% PSC
had moisture content of 57.91% which is significantly lower than
patty formulated with 50% which had moisture of 61.80%. In the
sensory evaluation, there were no differences recorded in all sensory
attributes of PSC-based patties judged by untrained panelists. In
conclusion, the addition of PSC to replace poultry meat can be
recommended for the purpose of lowering production cost, enhancing
nutritional composition and maintaining the acceptability of poultry
patties.
Abstract: The effect of plant growth-promoting rhizobacteria
(PGPR) on seed germination, seedling growth and yield of field
grown maize were evaluated in three experiments. In these
experiments six bacterial strains include P.putida strain R-168,
P.fluorescens strain R-93, P.fluorescens DSM 50090, P.putida
DSM291, A.lipoferum DSM 1691, A.brasilense DSM 1690 were
used. Results of first study showed seed Inoculation significantly
enhanced seed germination and seedling vigour of maize. In second
experiment, leaf and shoot dry weight and also leaf surface area
significantly were increased by bacterial inoculation in both sterile
and non-sterile soil. The results showed that inoculation with
bacterial treatments had a more stimulating effect on growth and
development of plants in nonsterile than sterile soil. In the third
experiment, Inoculation of maize seeds with all bacterial strains
significantly increased plant height, 100 seed weight, number of seed
per ear and leaf area .The results also showed significant increase in
ear and shoot dry weight of maize.
Abstract: This study was conducted using the data collected at the mouth of Jen-Gen River to investigate and analyze chromium (Cr) contained in the sediments, and to evaluate the accumulation of Cr and the degree of its potential risk. The results show that samples collected at all monitoring stations near the mouth of Jen-Gen River contain 92–567 mg/kg of Cr with average of 366±166 mg/kg. The spatial distribution of Cr reveals that the Cr concentration is relatively high in the river mouth region, and gradually diminishes toward the harbor region. This indicates that upstream industrial and municipal wastewater discharges along the river bank are major sources of pollution. The accumulation factor and potential ecological risk index indicate that the sedimentation at Jen-Gen River mouth has the most serious degree of Cr accumulation and the highest ecological potential risk.
Abstract: TTV is an unenveloped circular single-stranded DNA
virus with a diameter of 30-32 nm that first was described in 1997 in
Japan. TTV was detected in various populations without proven
pathology, including blood donors and in patients with chronic HBV
and HCV hepatitis. The aim of this study was to determine the
prevalence of TTV DNA in Iranian patients with chronic hepatitis B
and C. Viral TTV-DNA was studied in 442 samples (202 with HBV,
138 with HCV and 102 controls) collected from west south of Iran.
All extracted serum DNA was amplified by TTV ORF1 gene specific
primers using the semi nested PCR technique. TTV DNA was
detected in the serum of 8.9% and 10.8% patients with chronic
hepatitis B and C, respectively. Prevalence of TTV-DNA in the serum
of 102 controls was 2.9%. Results showed significant relation of TTV
with HBV and HCV in patients by using T test examination (P
Abstract: Fruit drying is a well known process mostly used for
preservation of fruits. Osmotic dehydration of apricot slices were
carried out in three different salt-sucrose concentrations and four
different temperatures. Also three different weight ratios of solution
to sample were conducted to one set of experiments. The dehydration
curves were constructed using Peleg-s model. Increasing the solution
volume increased the mass transfer rate and hence the solid gain
increased rapidly. Increasing the volume of osmotic media caused an
increase in overall mass transfer but a 'solution to sample' ratio of 5:1
gave the best product quality. The best temperature and concentration
that had a high water loss to solid gain ratio and an acceptable taste
were 40°C and 5%, respectively.

Abstract: Recently, a vehicular ad-hoc networks(VANETs) for
Intelligent Transport System(ITS) have become able safety and convenience services surpassing the simple services such as
an electronic toll collection system. To provide the proper services,
VANET needs infrastructure over the country infrastructure. Thus, we have to spend a huge sum of
human resources. In this reason, several studies have been made on the
usage of cellular networks instead of new protocols
this study is to assess a performance evaluation of the
cellular network for VANET. In this paper, the result of a
for the suitability of cellular networks for VANET
experiment, The LTE(Long Term Evolution) of cellular networks found to be most suitable among the others cellular networks
Abstract: In the framework of the image compression by
Wavelet Transforms, we propose a perceptual method by
incorporating Human Visual System (HVS) characteristics in the
quantization stage. Indeed, human eyes haven-t an equal sensitivity
across the frequency bandwidth. Therefore, the clarity of the
reconstructed images can be improved by weighting the quantization
according to the Contrast Sensitivity Function (CSF). The visual
artifact at low bit rate is minimized. To evaluate our method, we use
the Peak Signal to Noise Ratio (PSNR) and a new evaluating criteria
witch takes into account visual criteria. The experimental results
illustrate that our technique shows improvement on image quality at
the same compression ratio.
Abstract: According to dramatic growth of internet services, an easy and prompt service deployment has been important for internet service providers to successfully maintain time-to-market. Before global service deployment, they have to pay the big cost for service evaluation to make a decision of the proper system location, system scale, service delay and so on. But, intra-Lab evaluation tends to have big gaps in the measured data compared with the realistic situation, because it is very difficult to accurately expect the local service environment, network congestion, service delay, network bandwidth and other factors. Therefore, to resolve or ease the upper problems, we propose multiple cloud based GPES Broker system and use case that helps internet service providers to alleviate the above problems in beta release phase and to make a prompt decision for their service launching. By supporting more realistic and reliable evaluation information, the proposed GPES Broker system saves the service release cost and enables internet service provider to make a prompt decision about their service launching to various remote regions.
Abstract: Enterprise Architecture (EA) is a framework for description, coordination and alignment of all activities across the organization in order to achieve strategic goals using ICT enablers. A number of EA-compatible frameworks have been developed. We, in this paper, mainly focus on Federal Enterprise Architecture Framework (FEAF) since its reference models are plentiful. Among these models we are interested here in its business reference model (BRM). The test process is one important subject of an EA project which is to somewhat overlooked. This lack of attention may cause drawbacks or even failure of an enterprise architecture project. To address this issue we intend to use International Software Testing Qualification Board (ISTQB) framework and standard test suites to present a method to improve EA testing process. The main challenge is how to communicate between the concepts of EA and ISTQB. In this paper, we propose a method for integrating these concepts.
Abstract: In This paper, the behavior of eccentric braced frame
(EBF) is studied with replacing friction damper (FD) in confluence of these braces, in 5 and 10-storey steel frames. For FD system, the main step is to determine the slip load. For this reason, the performance indexes include roof displacement, base shear, dissipated energy and relative performance should be investigated. In
nonlinear dynamic analysis, the response of structure to three
earthquake records has been obtained and the values of roof
displacement, base shear and column axial force for FD and EBF
frames have been compared. The results demonstrate that use of the FD in frames, in comparison with the EBF, substantially reduces the roof displacement, column axial force and base shear. The obtained results show suitable performance of FD in higher storey structure in
comparison with the EBF.
Abstract: The Merrifield-Simmons index of a graph G is defined as the total number of its independent sets. A (n, n + 2)-graph is a connected simple graph with n vertices and n + 2 edges. In this paper we characterize the (n, n+2)-graph with the largest Merrifield- Simmons index. We show that its Merrifield-Simmons index i.e. the upper bound of the Merrifield-Simmons index of the (n, n+2)-graphs is 9 × 2n-5 +1 for n ≥ 5.
Abstract: Information and Communications Technologies (ICT) has been integrated in education in many developing and developed countries alike, but the use of ICT in Tanzanian schools is dismal. Many Tanzanian secondary schools have no computers. The few schools with computers use them primarily for secretarial services and computer literacy training. The Tanzanian education system at other levels like secondary school level has to undergo substantial transformation, underscored by the growing application of new information and communication technology. This paper presents the e-readiness survey result from secondary schools in Tanzania. The paper also suggests how Tanzania can make use of the few present ICT resources to support and improve teaching and learning functions to improve performance and acquisition of knowledge by using e-Learning Management System (e-LMS).
Abstract: In this work, we consider the rational points on elliptic curves over finite fields Fp where p ≡ 5 (mod 6). We obtain results on the number of points on an elliptic curve y2 ≡ x3 + a3(mod p), where p ≡ 5 (mod 6) is prime. We give some results concerning the sum of the abscissae of these points. A similar case where p ≡ 1 (mod 6) is considered in [5]. The main difference between two cases is that when p ≡ 5 (mod 6), all elements of Fp are cubic residues.
Abstract: to simulate the phenomenon of electronic transport in semiconductors, we try to adapt a numerical method, often and most frequently it’s that of Monte Carlo. In our work, we applied this method in the case of a ternary alloy semiconductor GaInP in its cubic form; The Calculations are made using a non-parabolic effective-mass energy band model. We consider a band of conduction to three valleys (ΓLX), major of the scattering mechanisms are taken into account in this modeling, as the interactions with the acoustic phonons (elastic collisions) and optics (inelastic collisions). The polar optical phonons cause anisotropic collisions, intra-valleys, very probable in the III-V semiconductors. Other optical phonons, no polar, allow transitions inter-valleys. Initially, we present the full results obtained by the simulation of Monte Carlo in GaInP in stationary regime. We consider thereafter the effects related to the application of an electric field varying according to time, we thus study the transient phenomenon which make their appearance in ternary material
Abstract: In recent decade's tourism industry is one of main
reasons of the social and economical development for many
countries; so these countries try to gain more portion of it for
themselves. The excessive natural and cultural touristy potentialities
in Iran made this country to be one of the most attractive sightseeing
areas, although; Iran has got the lowest rate of tourists. Khark Island
is about 32 km. It is a beautiful coral reef coast; about 98% of oil
export has been done through this place. The ecotourism
potentialities of Khark and Kharko Islands (about 3.7km far from
Khark) are the reason to consider ecotourism and the main activity in
these islands which is exporting oil at the same time. This article
refers to way of measuring the geographical coordination of the
place, and the potentialities, ecotourism attraction of the islands and
introduces some ideas in order to expand tourism in the islands.
Abstract: The aim of this paper is to confirm the effect of key
design parameters, the punch radius and punch angle, on rupture of the
expansion tube using a finite element analysis with a ductile damage
model. The results of the finite element analysis indicated that the
expansion ratio of the tube was mainly affected by the radius of the
punch. However, the rupture was more affected by the punch angle
than the radius of the punch. The existence of a specific punch angle,
at which rupture did not occur, even if the radius of the punch was
increased, was found.
Abstract: This paper presents a novel approach for the design of
microwave circuits using Adaptive Network Fuzzy Inference
Optimizer (ANFIO). The method takes advantage of direct synthesis
of subsections of the amplifier using very fast and accurate ANFIO
models based on exact simulations using ADS. A mapping from
course space to fine space known as space mapping is also used. The
proposed synthesis approach takes into account the noise and
scattering parameters due to parasitic elements to achieve optimal
results. The overall ANFIO system is capable of designing different
LNAs at different noise and scattering criteria. This approach offers
significantly reduced time in the design of microwave amplifiers
within the validity range of the ANFIO system. The method has been
proven to work efficiently for a 2.4GHz LNA example. The S21 of
10.1 dB and noise figure (NF) of 2.7 dB achieved for ANFIO while
S21 of 9.05 dB and NF of 2.6 dB achieved for ANN.
Abstract: In our modern society electricity is vital to our health,
safety, comfort and well-being. While our daily use of electricity is
often taken for granted, public concern has arisen about potential
adverse health effects from electric and magnetic – electromagnetic –
fields (EMFs) produced by our use of electricity.
This paper aims to compare between the measured magnetic field
values and the simulated models for the indoor medium to low
voltage (MV/LV) distribution substations.
To calculate the magnetic flux density in the substations,
interactive software SUBCALC is used which is based on closed
form solution of the Biot-Savart law with 3D conductor model.
The comparison between the measured values and the simulated
models was acceptable. However there were some discrepancies, as
expected, may be due to the current variation during measurements.
Abstract: The use of synthetic retardants in polymeric insulated
cables is not uncommon in the high voltage engineering to study
electrical treeing phenomenon. However few studies on organic
materials for the same investigation have been carried. .This paper
describes the study on the effects of Oil Palm Empty Fruit Bunch
(OPEFB) microfiller on the tree initiation and propagation in silicone
rubber with different weight percentages (wt %) of filler to insulation
bulk material. The weight percentages used were 0 wt % and 1 wt %
respectively. It was found that the OPEFB retards the propagation of
the electrical treeing development. For tree inception study, the
addition of 1(wt %) OPEFB has increase the tree inception voltage of
silicone rubber. So, OPEFB is a potential retardant to the initiation
and growth of electrical treeing occurring in polymeric materials for
high voltage application. However more studies on the effects of
physical and electrical properties of OPEFB as a tree retardant
material are required.
