Abstract: The present study was conducted to investigate the existence of polymorphism at transferrin (Tf) locus in the Carp (Cyprinus carpio). A polyacrylamide gel electrophoresis (PAGE) under alkaline condition method was used to distinguish Carp Tf alleles. Analysis of 116 samples revealed that all animals were polymorphic, showing many genotypes with clear biodiversity in the Tf gene. Seven Tf genotypes consisting of 4 homozygote types (CC, DD, FF and GG) and two heterozygote types (CD, DG and FG) were detected. These fractions are controlled by codominant autosomal genes according to the Mendelian laws of inheritance. The highest gene frequencies were calculated such as 0.50 for Tf D, 0.26 for Tf F and 0.12 for C and G. Thus, carp assemblages consistently tended to be more predominant to D allele. Differences between expected number and observed number for transferrin genotypes were no significant. Polyacrylamide electrophoresis, the technique employed in this study, allows rapid and efficient screening for the presence of polymorphism in Tf.

Advances in Materials Physics and Chemistry (AMPC) , 2015, DOI: 10.4236/ampc.2015.54015
Abstract: In-doped (Se0.7Te0.3) thin films (In: 0, 0.05, and 0.08wt%) with thickness of (150 ± 25 nm) have been deposited on glass substrates by chemical vapor deposition by using selenium, tellurium and indium whose purity is (99.99%) compound alloy. The electrical and optical properties of the thin films were analyzed. The effects of In-doping concentration on the thermoelectric properties of the thin films were investigated by room-temperature measurement of the See beck coefficient and electrical resistivity. The thermoelectric power factor shows the best result at 0.05wt% in doping. The See beck coefficients are positive with increasing in doping concentration from 0 to 0.08wt%. And the thin films show p-type conduction. For optical properties, the transmission of all samples was approximated to 90%.

International Journal of Advanced Computer Sciences and Applications , 2012,
Abstract: Today many of the activities are performed online through the Internet. One of the methods used to protect the data while sending it through the Internet is cryptography. In a previous work we proposed the Text-to-Image Encryption algorithm (TTIE) as a novel algorithm for network security. In this paper we investigate the efficiency of (TTIE) for large scale collection.
Ensuring Security, Confidentiality and Fine-Grained Data Access Control of Cloud Data Storage Implementation Environment  [PDF]

Journal of Information Security (JIS) , 2015, DOI: 10.4236/jis.2015.62013
Abstract: With the development of cloud computing, the mutual understandability among distributed data access control has become an important issue in the security field of cloud computing. To ensure security, confidentiality and fine-grained data access control of Cloud Data Storage (CDS) environment, we proposed Multi-Agent System (MAS) architecture. This architecture consists of two agents: Cloud Service Provider Agent (CSPA) and Cloud Data Confidentiality Agent (CDConA). CSPA provides a graphical interface to the cloud user that facilitates the access to the services offered by the system. CDConA provides each cloud user by definition and enforcement expressive and flexible access structure as a logic formula over cloud data file attributes. This new access control is named as Formula-Based Cloud Data Access Control (FCDAC). Our proposed FCDAC based on MAS architecture consists of four layers: interface layer, existing access control layer, proposed FCDAC layer and CDS layer as well as four types of entities of Cloud Service Provider (CSP), cloud users, knowledge base and confidentiality policy roles. FCDAC, it’s an access policy determined by our MAS architecture, not by the CSPs. A prototype of our proposed FCDAC scheme is implemented using the Java Agent Development Framework Security (JADE-S). Our results in the practical scenario defined formally in this paper, show the Round Trip Time (RTT) for an agent to travel in our system and measured by the times required for an agent to travel around different number of cloud users before and after implementing FCDAC.
Effect of Salt Stress on the Performance of Six Soybean Genotypes

Pakistan Journal of Biological Sciences , 2001,
Abstract: The effect of salinity on growth and chlorophyll content of six soybean genotypes was investigated. Plants were grown in nutrient solution in a greenhouse experiment to determine the effect of salinity on growth and Chl. a and b content of soybean leaves. Salinity was induced by natural drainage water of salted field to the nutrient solution. Electrical conductivities of the nutrient solution were 2,4,6,8,and l0 ds/m. Salinity induced marked decrease in plant growth and chlorophyll content of soybean genotypes. Increasing salinity level to l0 ds/m decreased plant height, shoot and root dry weight, and Chlorophyll a and Chlorophyll b contents. Soybean genotypes responded differently to increasing salt concentrations. There was a consistent in the percentages reduction of shoot dry weight and Chorophyll a and Chlorophyll b contents. It seems that Lee, Coniquitt and Clark 36k are more tolerant than other genotypes. Chlorophyll a and b content of soybean leaves with or without shoot dry weight can be use as a parameter in screening for salt tolerant in soybeans.

Asian Journal of Mathematics & Statistics , 2010,
Abstract: This study introduced the idea of using the novel ranked set sampling scheme for the Monte Carlo integral estimation problem. We proposed and discussed the unidimensional integral problem. It is demonstrated that this approach provides an unbiased and more efficient estimators than the traditional estimators based on simple random sampling. The method is illustrated by examples for estimating π and {f (x) = e-x2, 0≤x≤1}. An application to estimate the Gini index is proposed.

Abstract: The body weight records of 1221 heifers were used in this study collected from PT Taurus Dairy Farm Sukabumi from year 2001 until 2011. The records that could be used for analysis were 373 out of 1221 heifers, having completed data from birth to first mating period. Three different models i.e, Logistic, Gompertz, and von Bertalanffy were performed to analyze the growth rate of heifers. The results showed that the three models had different accuracy and heavily depend on age, environment and duration of recording. The body weights of sexual maturity and on certain ages were affected by the duration of recording. The Gompertz model was performed as the simpliest model in form of calculation. On the other hand, the Logistic was more difficult to calculate. All models indicated high accuracy with the determination coefficient (R2) more than 90%. Based on the comparison, the Gompertz and Logistic model are recommended for predicting the growth rate of heifers from birth to sexual maturity.

Journal of Fuels , 2014, DOI: 10.1155/2014/946485
Abstract: The experimental and simulated performance of an Armfield CM4 turbojet engine was investigated for palm oil methyl ester biodiesel (PME) and its blends with conventional Jet A-1 fuel. The volumetric blends of PME with Jet A-1 are 20, 50, 70, and 100% (B20, B50, B70, and B100). Fuel heating values (FHV) of each fuel mixture were obtained by calorimetric analysis. The experimental tests included performance tests for Jet A-1 and B20, while the performances of B50 to B100 were simulated using GasTurb 11 analytical software. In terms of maximum measured thrust, Jet A-1 yielded the highest value of 216?N, decreasing by 0.77%, 4%, 8%, and 12% with B20, B50, B70, and B100. It was found that B20 produced comparable results compared to the benchmark Jet A-1 tests, particularly with thrust and thermal efficiency. Slight performance penalties occurred due to the lower energy content of the biodiesel blends. The efficiency of the combustor improved with the addition of biodiesel while the other component efficiencies remained collectively consistent. This research shows that, at least for larger gas turbines, PME is suitable for use as an additive to Jet A-1 within 50% blends. 1. Introduction There is a general consensus within the literature that fossil fuel feedstock used for the production of aviation-grade kerosene fuel is dwindling. Koh and Ghazoul [1] expected a peak oil production scenario within the years 2010–2020, assuming that global oil consumption increases to 118 million barrels per day in 2030. Nygren et al. [2] projected that civil aviation traffic growth will increase at a rate of 5% per year, while fuel consumption will increase at 3% per year. Lee et al. [3] projected that aviation traffic growth will increase by 4.5% to 6% per year over the next twenty years, with traffic doubling every 15 years. This is further supported by the recent report by Deloitte [4], whereby passenger travel demand is expected to increase 5% over the next 20 years, contributing to increases in aircraft production. Despite the improvements in aircraft fuel efficiency since 1960 [5], further efforts need to be made in order to mitigate the dependency on traditional fuel sources and to replace current petrol-based fuels. Biodiesel is produced through the transesterification of pure vegetable or organic oils by replacing the triglyceride molecules with lighter alcohol molecules such as methanol or ethanol. The reaction is carried out with a strong base catalyst, producing glycerol in addition to transesterified vegetable oils (biodiesel) [6]. Canakci et al. [7] claimed that
