In this research work, the production of undoped and silver (Ag) doped zinc oxide (ZnO) thin films for food-packaging applications were developed. The main goal was to determine the influence of coatings morphology and thickness on the antimicrobial performance of the produced samples. The ZnO based thin films were deposited on PET (Polyethylene terephthalate) substrates by means of DC reactive magnetron sputtering. The thin films were characterized by optical spectroscopy, X-Ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Scanning Electron Microscopy (SEM). The antimicrobial performance of the undoped and Ag-doped ZnO thin films was also evaluated. The results attained have shown that all the deposited zinc oxide and Ag-doped ZnO coatings present columnar morphology with V-shaped columns. The increase of ZnO coatings thickness until 200 nm increases the active surface area of the columns. The thinner samples (50 and 100 nm) present a less pronounced antibacterial activity than the thickest ones (200–600 nm). Regarding Ag-doped ZnO thin films, it was verified that increasing the silver content decreases the growth rate of Escherichia coli and decreases the amount of bacteria cells present at the end of the experiment © 2014 Elsevier B.V.

Network Testing : An Overview of Approaches

Todays networks are very large in size as well as complex by design. Validating today’s networks against any problem is really cumbersome task with traditional approaches like ping, traceroute, tcpdump etc. Networks are generally susceptible to problems like loop, black-hole, drop, software bugs and physical failures. Protecting networks from these kind of problems using traditional approaches is complicated and time consuming which is not at all affordable in any enterprise scale networks. To avoid loss caused due to network problems, one should have tools which can validate network against above said problems in less time as soon as they are introduced in network. Researchers have developed many state of the art tools like HSA, ATPG, Veriow, Anteater, NetPlumber. These tools are capable of detecting forwarding state anomalies with minimum human intervention. Approaches used in above tools can be broadly classified into two categories i.e. static validation and dynamic validation. Static validation is capable of detecting loop, drop and black-hole along with these, dynamic validation can detect problem caused due to software bug and physical failure. In this paper we will study general network problems, approaches to tackle them and some of their implementations in detail.
‘I think it adds value, but I don’t use it’: use, perceptions and attitudes of outdoor exercise equipment in an urban public park

ABSTRACT Public open spaces are important places that can contribute to public health initiatives through facilitating leisure-time physical activity. Using the findings from 400 self-completed questionnaires of park visitors, this exploratory study examined people’s use, perception and attitudes of a specific type of outdoor exercise equipment (in the form of a stretch station circuit) installed in an urban public park in a suburb of Perth, Western Australia. The data highlights that the equipment is positively perceived by existing park users in that it is seen to add value to the park and is a ‘good investment’ by their local government authority. Users of the equipment did enjoy it and wanted more installed. However, there appears to be little perceived benefit in terms of its contribution to the physical activity levels of park users, particularly with regard to a key target group – those people who engage in little leisure-time physical activity.
Identification and Evaluation of the Interest of College Students In becoming Entrepreneurs

We see that there are many more fresh graduates looking for jobs when they finish their study than there are graduates creating new jobs. The aim of the study is to identify and evaluate the entrepreneurial interests of Indonesian college students by using the Focus Group Discussion method (FGD) on accounting students in Lampung Province. Five FGD groups, each consisting of five to seven participants, provided data which we examined using Nvivo analysis qualitative software. We found an overall reluctance of students to be entrepreneurs, based on both intrinsic and extrinsic factors. This study implies that encouraging students to be entrepreneurs should be done by all parties, to stimulate them to create jobs, increase economic activity, open new markets, and hire more employees
Prethermalization and Thermalization in Isolated Quantum Systems

Prethermalization has been extensively studied in systems close to integrability. We propose a more general, yet conceptually simpler, setup for this phenomenon. We consider a --possibly nonintegrable-- reference dynamics, weakly perturbed so that the perturbation breaks at least one conservation law of the reference dynamics. We argue then that the evolution of the system proceeds via intermediate (generalized) equilibrium states of the reference dynamics. The motion on the manifold of equilibrium states is governed by an autonomous equation, flowing towards global equilibrium in a time of order $g^{-2}$, where $g$ is the perturbation strength. We also describe the leading correction to the time-dependent reference equilibrium state, which is, in general, of order $g$. The theory is well-confirmed in numerical calculations of model Hamiltonians, for which we use a numerical linked cluster expansion and full exact diagonalization.
The influence of environmental conditions on the morphological variability of phytoplankton in an oligo-mesotrophic Turkish lake

2Phytoplankton dynamics and morphological plasticity were studied in an oligo-mesotrophic lake from late spring to early autumn in 2004 on a weekly to bi-weekly basis. This study aimed to evaluate the effect of environmental constraints on morphological plasticity and size structure of dominant species through the stratified period of the lake. While centric diatoms developed mainly in the epilimnion, Fragilaria crotonensis, Synedra sp. and Synedra acus were very well distributed through the whole water column, as was the cryptophyte Plagioselmis nannoplanctica. A filamentous cyanobacterium, Planktothrix rubescens, was stratified in the metalimnion throughout the sampling period, while Mougeotia sp. was entrained through the whole water column during the early autumn. Surface area / volume (S/V) ratios were calculated for the dominant species on each sampling date. The minimum S/V ratio was found with centric diatoms, while maximal values measured were for Synedra sp. and Asterionella formosa. The S/V ratio of the only dominant cryptophyte, Plagioselmis nannoplanctica was also high; variations were negatively correlated with NO3-N and PO4-P (-0.62 and -0.61, respectively) and positively correlated with euphotic depth (r=0.57) and temperature (r=0.82). On the other hand, the S/V ratios of Fragilaria crotonensis and Cyclotella ocellata each showed strong negative correlation with silica concentrations (-0.55 and -0.62, respectively). It is concluded that allometric relationships showed significant differences among species according to depth and season.
A survey on human detection for video surveillance system

-Detecting human beings perfectly in a visual surveillance system is crucial for diverse application areas including abnormal event detection, human gait characterization, person identification, gender classification and fall detection for elderly people. The first step of the detection process is to detect an object which is in motion. Object detection is used three methods: background subtraction, optical flow and spatio-temporal filtering techniques. Once detected, a moving object could be classified as a human being using shape-based, texture-based and motion-based features.
Effect of cereal grains on the total lipid, cholesterol content and fatty acid composition of liver and muscle tissues in native geese.

In this study we evaluated the effect of cereal grains on total lipid, cholesterol content and fatty acid composition of liver and muscle tissues in native geese. The thirty five geese used in the study were divided into five groups of seven. The groups of geese feed with barley, wheat, rye and corn, respectively. The first group was used as the control group. Water and feed were provided for ad libitum consumption for 6 weeks. While the level of total cholesterol in the liver tissue decreased (P<0.001) in barley and wheat groups, it of the thigh muscle decreased (P<0.001) in all groups. While the total lipid content of the liver tissue increased in rye and corn groups (P<0.001), it of the thigh muscle increased (P<0.001) in wheat and rye groups. While the total lipid content of the back muscle decreased in barley and wheat groups (P<0.001), it of the breast muscle decreased (P<0.001) in wheat, rye and corn groups. Although the amount of palmitic acid in the liver tissue increased (P<0.001) in the rye group, the amount of stearic decreased (P<0.001) in the barley group. The amount of arachidonic, docosahexaenoic, PUFA, n-3 and n-6 acids in the liver tissue increased (P<0.001) in the wheat, rye and corn groups. Consequently, in addition to other foods, rye could be used as a valuable nutrition of the geese diet.
Spam Detection Using SVM and RBF

In today‘s life internet is an important part. We spend most of our time on internet. One of the important features of internet is communication. Email is a mode of communication which is used for the personal and business purpose. Spam emails are the emails recipient does not wish to take delivery of; it is also called unwanted bulk email. Emails are used each day by number of user to converse around the world. At present large volumes of spam emails are reasoning serious trouble for Internet user and Internet service. Such as it degrade user investigate knowledge, it assists transmission of virus in network, it increases load on network traffic. It also misuses user time, and energy for legal emails among the spam. For evade spam there are so many conventional anti-spam technique includes Bayesian based sort, rule based system, IP blacklist, Heuristic based filter, White list and DNS black holes. These methods are based on satisfied of the post or links of the mail. In this paper we proposed an efficient spam filtering technique based on neural network. The technique used is RBF a neural network technique in which neuron are trained. The results obtained by using this technique are compared with SVM. The parameter meter for comparison is precision and accuracy. On the basis of these two parameters we compared the proposed technique with SVM.
Low-lying baryon spectrum with two dynamical twisted mass fermions

The masses of the low-lying baryons are evaluated using two degenerate flavors of twisted mass sea quarks corresponding to pseudoscalar masses in the range of about 270\char21{}500 MeV. The strange valence quark mass is tuned to reproduce the mass of the kaon in the physical limit. The tree-level Symanzik improved gauge action is employed. We use lattices of spatial size 2.1 and 2.7 fm at two values of the lattice spacing with ${r}_{0}/a=5.22(2)$ and ${r}_{0}/a=6.61(3)$. We check for both finite volume and cutoff effects on the baryon masses. We performed a detailed study of the chiral extrapolation of the octet and decuplet masses using SU(2) $\ensuremath{\chi}\mathrm{PT}$. The lattice spacings determined using the nucleon mass at the physical point are consistent with the values extracted using the pion decay constant. We examine the issue of isospin symmetry breaking for the octet and decuplet baryons and its dependence on the lattice spacing. We show that in the continuum limit isospin breaking is consistent with zero, as expected. The baryon masses that we find after taking the continuum limit and extrapolating to the physical limit are in good agreement with experiment.
Nonordinary light meson couplings and the 1/N_c expansion

We study the large N_c behavior of couplings among light meson states with different compositions in terms of quarks and gluons. We shortly review the most common compositions of mesons, which are of interest for the understanding of low-lying meson resonances, namely, the ordinary quark-antiquark states as well as the nonordinary glueball, tetraquark, and other states. We dedicate special attention to Jaffe's generalization of the tetraquark with N_c - 1 q -q over bar q pairs, which is the only type of state we have identified whose width does not necessarily vanish with N_c, though it does decouple exponentially with N_c from the ππ channel, so that it is weakly coupled to the meson-meson system.
Feldspathic rocks on Mars: Compositional constraints from infrared spectroscopy and possible formation mechanisms

Rare feldspar‐dominated surfaces on Mars were previously reported based on near‐infrared (NIR) spectral data and were interpreted to consist of anorthosite or felsic rocks. Using thermal infrared (TIR) data over the feldspar detections with the largest areal extent in Nili Patera and Noachis Terra, we rule out felsic interpretations. Basaltic or anorthositic compositions are consistent with TIR measurements, but the geologic contexts for these regions do not support a plutonic origin. Laboratory NIR spectral measurements demonstrate that large plagioclase crystals (>~840 µm) can be detected in mixtures with as much as 50 vol % mafics, which is higher than the previously stated requirement of no more than 15% mafics. Thus, anorthositic or felsic interpretations need not be invoked for all NIR‐based feldspar detections. Plagioclase‐enriched basaltic eruptive products can be formed from Martian basalts through partial crystallization at the base of a thick crust, followed by low‐pressure crystallization of the residual liquids.
Ethnonationalist Triads: Assessing the Influence of Kin Groups on Civil Wars

Although the case-based literature suggests that kin groups are prominent in ethnonationalist conflicts, quantitative studies of civil war onset have both overaggregated and underaggregated the role of ethnicity, by looking at civil war at the country level instead of among specific groups and by treating individual countries as closed units, ignoring groups' transnational links. In this article the authors integrate transnational links into a dyadic perspective on conflict between marginalized ethnic groups and governments. They argue that transnational links can increase the risk of conflict as transnational kin support can facilitate insurgencies and are difficult for governments to target or deter. The empirical analysis, using new geocoded data on ethnic groups on a transnational basis, indicates that the risk of conflict is high when large, excluded ethnic groups have transnational kin in neighboring countries, and it provides strong support for the authors' propositions on the importance of transnational ties in ethnonationalist conflict.
Rain forest vegetation of 'Eua Island, Kingdom of Tonga.

Abstract The indigenous vegetation of 'Eua Island, Tonga, is described and a species list presented. Quantitative data were collected from 40 forest plots in which all vascular plant species were recorded and the diameters of all stems ≥ 5 cm dbh were measured. Plot classification, based on basal area data, identified six forest types, two coastal and four inland, which reflect an elevational sequence from the coast to the island's summit (312 m a.s.l.). A polar ordination, based on basal area data, arranged plots from the four inland forest types in a sequence from low to high elevation along one ordination axis, and from more mature to less mature along a second axis. Species richness increased with elevation. Several additional, non-forest vegetation types, including fern- and grass-dominated vegetation of inland ridges and shrub-dominated vegetation of cliffs and rocky shores, were sampled semi-quantitatively and are also described.
Neutron diffraction study of phase transitions and thermal expansion of SrFeAsF

The magnetic ordering and crystal structure of iron pnictide SrFeAsF was investigated by using neutron powder-diffraction method. With decreasing temperature, the tetragonal to orthorhombic phase transition is found at 180(2) K while the paramagnetic to antiferromagnetic phase-transition set in at 133(3) K. The big difference between structural and magnetic phase transitions in SrFeAsF indicates the weak magnetic exchange coupling between Fe layers. Similar to the parent compound of other iron-pnictide system, the striped Fe magnetism is confirmed in antiferromagnetic phase and the Fe moment of $0.58(6){\ensuremath{\mu}}_{B}$ aligned along long $a$ axis. Given the fact that long-range antiferromagnetic order can be described by a power law with $\ensuremath{\beta}=0.124(16)$, SrFeAsF can be treated as a quasi-two-dimensional Ising system. Thermal expansion of orthorhombic phase of SrFeAsF is also investigated. Based on the Gr\"uneisen approximation and Debye approximation for internal energy, the volume of SrFeAsF can be well fitted with Debye temperature of 347(5) K. The experimental atomic-displacement parameters for different crystallographic sites in SrFeAsF are analyzed with Debye model. Thermal expansion analysis for SrFeAsF suggested that the expansion of FeAs layers plays an important role in determining the thermal expansion coefficient.
Development and Initial Validation of the Chinese Version of Psychological Needs Thwarting Scale in Physical Education.

The current study presents the development process and initial validation of a measure designed for assessing psychological needs thwarting (frustration) in a secondary school physical education context (Psychological Needs Thwarting Scale in Physical Education, PNTSPE). Secondary school students (grades 7–9) from Hong Kong (N = 1258) were invited to participate in three studies. In Study 1, item generation and initial content validity of the PNTSPE were achieved. In Study 2, the factorial structure of the measure was tested using exploratory and confirmatory factor analysis. Internal consistency reliabilities of the subscales were also examined. In Study 3, the reliability and validity of the scores derived from the PNTSPE were further examined in an independent sample. Overall, the findings from the three studies provided initial psychometric evidence for the PNTSPE and suggested that the PNTSPE could be used as a valid and reliable measure to assess Hong Kong secondary school students’ psychological ne.
Oncolytic Viruses: A Gene Therapy for Treatment of Cancer in Companion Animals

Cancer is the leading cause of disease-related death in companion animals such as dogs and cats. Oncolytic viruses refer to those viruses that will selectively eliminate and lysis cancerous tissues without causing harm to normal tissues. Oncolytic viruses can kill infected cancer cells in many different ways, ranging from direct virusmediated cytotoxicity through a variety of cytotoxic immune effector mechanisms. Treatment of pet cancer with advanced disease stages is very poor prognosis. Therefore, developing unique cancer therapies is essential for work synergistically in combination with the conventional treatment options. Several oncolytic viruses including canine distemper virus, adenovirus strains, and vaccinia virus strains have been used for canine cancer therapy in preclinical studies. This review is focused on the probable use of oncolytic viral agents for canine cancer therapy in the future.
2 VULNERABILITY SCANNERS ( VS ) : ARCHITECTURE , LIMITATIONS AND TESTING PROCEDURES 2 . 1 Architecture of VS

Currently we observe increasing popularity of web technology that allows for reflecting traditional businesses into web-based applications (web applications, for short). Such web applications are often interesting to hackers aiming at stealing (confidential) user information; they would use such information for personal gain. For providing the enough security level of computer and information systems the companies should be interested in the regular information security active auditing. This process often accompanies the checking and control of the security systems of enterprises but it is usually expensive by finance, time and human resources consuming. The one of the tools for active security audit is the using of vulnerability scanners especially for web applications security assessment. During the process of the web applications checking the vulnerability scanners discover a lot of bugs in applications security system and inform the users (auditors) by providing the list of vulnerabilities. Despite of the various types of vulnerability scanners only few of them may contain the intelligent tools which can facilitate the auditing process. Therefore, there is a high demand for the development of intelligent security scanners that are compliant with the de facto security standard of OWASP the Open Web Application Security Project. We argue that embedding intelligent tools (expert systems) in such vulnerability scanners would not only increase effectiveness but would also decrease the cost of an OWASP auditing process. We can claim that using fuzzy sets and logic theories may facilitate this process in terms of processing that concerns the human expert contributions.
Size- and Shape-Controlled Synthesis of Monodisperse Metal Oxide and Mixed Oxide Nanocrystals

A nanocrystal or nanoparticle (not fully crystalline) is defined as a particle with size in range of 1 to 100 nm (102 to 107 atoms) from zero (0D) to three dimensions (3D), which exhibits the unique physiochemical properties due to the quantum size effect that cannot be anticipated from bulk counterparts. Strictly speaking, the name of “nanocrystal” is only used for crystalline nanoparticle, and is however a more general term which can refer to both crystalline and non-crystalline nanoparticles. Accordingly, their particle size is intermediate between the size of molecule and bulk solid (Rao, Muller and Cheetham 2005, Sorensen 2009). Nanocrystals can be formed in a variety of shapes including dot, sphere, cube, rod, triangle, hexagon and many others. In this size range, they possess an immense surface area per unit volume, a very large percentage of atoms in the surface. As a result, their unexpected properties can be obtained as compared to those of both individual atoms/molecules and bulk counterpart of the same chemical composition. Sizeand shape-dependent properties of the nanocrystals can be tuned by changing the dimension and designing the shape (Rao et al. 2005). Due to the materials at the nanoscale, low coordination number, surfaced edge and corner atoms are usually chemically reactive, catalytically active and polarisable surface, contributing to their high chemical potential. For example, the high surface area is of particular importance regarding heterogeneous catalytic reactions, because of the increase of interaction of reactive molecules and active sites on the catalyst surface (Abbet and Heiz 2005). Furthermore, the particle size not only affects their surface area, but also arise new properties, due to the quantum-size effect (e.g., electron confinement and surface effect) (Kroes et al. 2002, Kamat et al. 2010). Considerable efforts have recently been devoted to the preparation of metal oxide and mixed oxide nanomaterials due to both their unique properties and their technological applications (Seshadri 2005, Burda et al. 2005, Mao et al. 2007, Yin and Alivisatos 2005). Metal oxides including the transition metals and rare earths, display a wide variety of complex structures and interesting electronic and magnetic properties associated with the changes in electronic structure and bonding and in the presence of ordered defect complexes or extended defects. The nanostructured mixed oxides can greatly generate new synergetic properties and improve the overall application performance, that is not available from single metal oxide species, due to the appropriate combination of individual oxide
