Visualization Detection of Melamine in the Protein Feed

Methane-oxidizing bacteria is the branches of methyl oxidation bacteria, It is a kind of gram-negative bacteria, which can directly use methane as carbon and energy sources. Methanobactin (Mb) is a fluorescent peptide released by the Methane oxidizing bacteria. It consists of two serine, glycine, two cysteine and methionine. Methanobactin (Mb) can coordinate Cu(I) by two hydroxyimidazolates, with one N and one S atom. Methanobactin (Mb) can also bind to Au(III) and reduce it to Au(0). In the presence of hydroquinone as a electron donator, Mb can catalyze Au(III) reduce to Au(0) and yield gold nanoparticles continuously. Surface plasmon resonance of gold nanoparticles makes its aqueous solution has a typical absorption peak between 500 and 600nm, and a unique color of that can be observed by naked eyes. It can be identified by the color change and used in the detection of certain substances. In this paper, visual detection of melamine in protein feed based on methanobactin-(Mb) induced gold nanoparticles formation was studied. Visual detection is convenient and quick. Different concentrations of melamine in protein feed have been detected. The interference of several kinds of ingredients in protein feed have been investigated. The detection limit and the recovery rate have been calculated, either. The detection limit of melamine is much lower than 1 ppm.
VIRTUAL SPACE 4D PROJECT: THE ROOM ACOUSTICAL TOOL

Computer aided room acoustical models have been applied for more than ten years as an everyday tool in different types of acoustical problems. The most interesting applications can be found among concert halls, but the application to auditoriums, open-plan offices and industrial workrooms is also usual. However, this does not mean that modelling is used in every important building project as a normal design practice. It requires both acoustical regulations and experienced consultant companies before the modelling can become a best design practice. At least in Finland, the present situation is very dispersed.
Impact of leukocytapheresis on the coagulation and lung injury in the endotoxemia dogs

To explore the role of leucocyte in the coagulation and fibrinolysis system in endotoxin-induced lung injury, the impact of peripheral leukocytapheresis (LCAP) on the coagulation and fibrinolysis system, and the lung injury in the endotoxemia dogs were observed. Endotoxemia was introduced in dogs with lipopolysaccharidea (LPS, 2 mg/kg). A total of 30 dogs were randomly assigned into LPS group (dogs were treated with LPS alone), sham group (dogs underwent LPS treatment and then sham LCAP 12-14 h later) and LCAP group (dogs underwent LPS treatment and LCAP 12-14 h later) (n=10 per group). The levels of peripheral activator protein C (APC), soluble thrombomodulin (sTM) and plasminogen activator inhibitor-1 (PAI-1) were measured 0 h before LPS treatment and 2, 6, 12, 14, 16, 24 and 36 h after LPS treatment. Result showed that the serum level of APC at 14 and 16 h after LPS treatment in LCAP group was significantly higher than that in LPS group at corresponding time points (P<0.05). The serum levels of sTM and PAI-1 at 14 and 16 h after LPS treatment in LCAP group was significantly lower than those in LPS group at corresponding time points (P<0.05). The incidence of lung injury in LCAP group was lower than that in LPS group (P<0.05). At the early stage of endotoxemia, LCAP can improve the balance of coagulation and fibrinolysis which may partly contribute to the improvement of oxygenation index and attenuation of lung injury.
A study on human activity recognition based on acceleration-angular velocity data and link mechanism

Recently human activity recognition and behavior analysis are often studied aiming at the service deployments to fields of the medical treatment and security. For observing human activities, previous works are basically grouped into two types of systems ; one is based on video and wearable sensors and the other is on the motion capture system designed for analyzing human joint construction. The video and motion capture system is easy to consider joint construction, but it requires the laboratory room for filming 3D data. In contrast, acceleration sensor is easily handled in sense that we do not need any other facilities. However, it can not measure joint structures and body sizes because the data obtaining from the sensor are only accelerations. In this article we propose a statistical method of estimating displacement angle of shoulder joint based on only one acceleration-gyro sensor. We model the displacements of the angle of the shoulder joint in each movement direction of the arm and estimate the parameters of the arm by nonlinear optimization techniques. We also show that our method can give a better classification in case of applying to gym exercise.
Opposition-Based Improved PSO for Optimal Reactive Power Dispatch and Voltage Control

An opposition-based improved particle swarm optimization algorithm (OIPSO) is presented for solving multiobjective reactive power optimization problem. OIPSO uses the opposition learning to improve search efficiency, adopts inertia weight factors to balance global and local exploration, and takes crossover and mutation and neighborhood model strategy to enhance population diversity. Then, a new multiobjective model is built, which includes system network loss, voltage dissatisfaction, and switching operation. Based on the market cost prices, objective functions are converted to least-cost model. In modeling process, switching operation cost is described according to the life cycle cost of transformer, and voltage dissatisfaction penalty is developed considering different voltage quality requirements of customers. The experiment is done on the new mathematical model. Through the simulation of IEEE 30-, 118-bus power systems, the results prove that OIPSO is more efficient to solve reactive power optimization problems and the model is more accurate to reflect the real power system operation.
Potential Health Effects of Enzymatic Protein Hydrolysates from Chlorella vulgaris

Background and Objective: Chlorella vulgaris is a multi-cellular edible algal species with abundant proteins. Extraction of high value protein fractions for pharmaceutical and nutritional applications can significantly increase the commercial value of microalga biomasses. There is no known report on the anticancer peptides derived from the Chlorella vulgaris abundant protein. Materials and Methods: This study examined the antimicrobial and anticancer effects of peptides from a hydrolyzed Chlorella vulgaris protein with 62 kDa molecular weight. Protein hydrolysis was done by pepsin as a gastrointestinal protease, and was monitored through protein content measurement, sodium dodecyl sulfate polyacrylamide gel electrophoresis, and high performance liquid chromatography measurements. Inhibitory effect of the produced peptides on Escherichia coli cells and breast cancer cell lines was assayed. Results and Conclusion: Hydrolyzed peptides induced a decrease of about 34.1% in the growth of Escherichia coli, and the peptides of 3 to 5 kDa molecular weight had strong impact on the viability of breast cancer cells with IC50 value of 50 μg μl-1. The peptide fractions demonstrating antimicrobial and anti-cancer activities have the potential for use as functional food ingredients for health benefits. These results demonstrate that inexpensive algae proteins could be a new alternative to produce anticancer peptides. Conflict of interest: The authors declare that there is no conflict of interest.
Effect of Sophorolipid Biosurfactant on Oil Biodegradation by the Natural Oil-Degrading Bacteria on the Weathered Biodiesel, Diesel and Light Crude Oil

This study investigated the role of natural oil-degrading bacteria in the weathered biodiesel (BD), diesel (D) and light crude oil (L) in oil biodegradation in seawater with and without sophorolipid biosurfactant. Mixtures of artificial seawater and weathered oil with and without sophorolipid dispersant were incubated at 22 ± 1°C and 100 rpm for 28 days. Analysis of the remaining of total petroleum hydrocarbons showed degradation of 43 ± 0.7%, 45 ± 5.7% and 39 ± 4.6% of biodiesel, diesel and light crude oil, respectively, during the natural biodegradation and 44 ± 5%, 47.5 ± 3.9% and 44 ± 1% of biodiesel, diesel and light crude oil, respectively, with sophorolipid by the existing bacteria after 28 days. Characterization of bacteria isolated from the BD, D and L oil by 16S rRNA pyrosequencing showed that the Firmicutes was the dominant phylum in biodiesel (100%) and diesel (53%). The Actinobacteria was dominant in the diesel (47%) and the Proteobacteria (97%) and Actinobacteria (3%) were the two dominant phyla in the light crude oil. The hydrophobicity results showed that the bacteria consumed the hydrocarbons mainly by changing their cell surface structures in the natural biodegradation treatment and increase in the micellar dispersion of hydrocarbons in the biodegradation treatment with the sophorolipid. This study confirmed the significant contribution of natural bacteria in the weathered diesel, biodiesel and light crude oil in the biodegradation and the positive effect of sophorolipid on the biodegradation.
Off the Rack Versus Savile Row: The Value of Custom Tailoring for Equity Investors

Equity asset managers within professional investment advisory firms will often manage both discretionary fee-based accounts as well as open-ended mutual funds - using comparable domestic equity investment disciplines. When retail and institutional investors choose between these products, their decision often hinges on performance and portfolio customization. After reconciling each product’s gross performance for calculation methodology, management and trading costs, and systematic risk measures, we find that concurrently-managed (where the same personnel manage a separately managed account and an open-ended mutual fund over the same time period using identical investment disciplines) small-cap separately managed accounts outperform small-cap actively-managed open-ended mutual funds between 1998 and 2003. We argue that this difference in performance is attributable to differences in asset growth as well as an advisory firm’s reluctance to accept smaller separately managed accounts.
A different look over the financial depth nonlinearity: Evidence from Europe

A relacao nao linear entre Crescimento Economico e Profundidade Financeira foi avaliada com recurso a um painel de 25 paises europeus, para o periodo compreendido entre 1996 e 2011. Estes paises partilham padroes espaciais comuns como foi confirmado pela presenca de dependencia seccional. Alem disso, foi identificado heterocedasticidade e autocorrelacao de primeira ordem no painel. O teste de Hausman suporta a presenca de heterogeneidade, selecionando o modelo de efeitos fixos. Foi utilizado o estimador Driscoll e Kraay com efeitos fixos, que e robusto a estes fenomenos. A nao linearidade da relacao entre Crescimento Economico e Profundidade Financeira foi confirmada pelo U-teste de Lind e Mehlum. Pode-se concluir que o incremento na profundidade financeira restringe o Crescimento Economico para os paises europeus. Como tal, a dimensao otima do sector financeiro deve ser considerada pelos decisores de politica economica.
Flood Assessment in the Context of Sustainable Development using the DPSIR Framework

The assessment in the context of sustainable development is a holistic approach for assessing the impacts and trade-offs related to various land and water management options. It is a procedure in which a knowledge-based approach should be derived to develop a basis for decision making. A Diver-Pressure-State-Impact-Response (DPSIR) framework has been adopted to carry out the assessment. It is illustrated in the case of Gorganrood Basin (located in the north east of Iran) for the issue of flood to describe the relationship between the origin and consequences of flooding and also to understand the dynamics underpinning the problem. The analysis of the state of flood by DPSIR shows that the responses in Gorganrood Basin have led to inadequate problem-solving results not even effective to reduce system sensitivity to flood in the long term. In the context of DPSIR some reasonable responses may be regarded as decreasing the rates of urbanization, deforestation, land consolidation, and immigration; watershed management programs; and river dredging. DPSIR helps in structuring data in a reasonable way and allows decision makers to trace step wise fundamental problem drivers and explores leverage points where appropriate responses can be exerted.
AlN Based RF MEMS Tunable Capacitor with Air-Suspended Electrode with Two Stages

In this paper, a MEMS tunable capacitor was successfully designed and fabricated using an aluminum nitride film and a gold suspended membrane with two air gap structure for commercial RF applications. Unlike conventional two-parallelplate tunable capacitors, the proposed tunable capacitor consists of one air suspended top electrode and two fixed bottom electrodes. One fixed and the top movable electrodes form a variable capacitor, while the other one provides necessary electrostatic actuation. The fabricated tunable capacitor exhibited a capacitance tuning range of 375% at 2 GHz, exceeding the theoretical limit of conventional twoparallel-plate tunable capacitors. In case of the contact state, the maximal quality factor was approximately 25 at 1.5 GHz. The developed fabrication process is also compatible with the existing standard IC (integrated circuit) technology, which makes it suitable for on chip intelligent transceivers and radios.
Photoconductivity in High-Quality Graphene

Graphene is a relatively new material with unique properties that found application in the field of electronics and optoelectronics. A broadband absorption makes it especially interesting for photodetection applications. Middle-infrared domain of electromagnetic spectrum still lacks active media for photodetection that are cheap, do not contain toxic elements and do not require additional cooling. This work is focused on the fabrication of a graphene-based photodetector for middle-infrared domain and on the photoresponsivity mechanisms in this region where direct absorption by graphene does not play the dominant role. Several steps to improve the device quality are considered and the photocurrent measurements in the middle-infrared are performed and analysed. The substrate properties such as dielectric permittivity dispersion of the silicon oxide and the hyperbolic nature of hexagonal Boron Nitride are found to introduce essential contribution to the photocurrent enhancement mechanism.
Performance Study of Solar Power Source for Wireless Systems

Photovoltaic (PV) technology is an attractive power source for systems with no wired connections to any network. Because of seasonal variations of solar irradiation, designing such a system requires careful analysis in order to provide required level of reliability. In this paper we present results of 16-month measurements of experimental PV system located in Poland. Obtained irradiation values have been verified with reference data from independent sources. The results of this work may be helpful in forecasting the performance of similar PV systems in the same region and allow to make more precise forecasts of power system performance than based only on average monthly irradiation tables. Keywords—photovoltaics, renewable energy, solar irradiation, wireless power systems
Um Classificador para Seleção de Características Aplicado a Problemas Não-Linearmente Separáveis

Resumo—Este artigo apresenta uma abordagem robusta para o problema de seleção de caracterı́sticas aplicado a conjuntos de dados não-linearmente separáveis. Neste sentido, foram realizados estudos comparando-se resultados relativos a utilização de classificadores baseados em funções kernel, os quais produzem o processo de seleção em um espaço de mais alta dimensão, denominado espaço kernel, com classificadores robustos, que utilizam o conceito de margem flexı́vel e permitem uma tolerância a erros de classificação promovendo a seleção de caracterı́sticas diretamente no espaço de entrada. A introdução do processo de flexibilização da margem possibilita a correta classificação de dados, que não sejam linearmente separáveis no espaço de entrada, refletindo em uma melhora do poder de generalização. Tal fato pode ser comprovado pela redução de erros nos testes experimentais. Também, a opção pela minimização da norma L1 do vetor normal ao hiperplano separador, tornou possı́vel a construção de hipóteses com alto grau de esparsidade. De fato, esta forma de otimização, que apresenta um processo de regularização interna, contribui de forma significativa para uma melhor eficiência do processo de seleção de caracterı́sticas. Para a seleção dos melhores subconjuntos, os classificadores foram associados a um algoritmo de busca ordenada que utiliza os valores de margem como medida de avaliação dos subconjuntos candidatos. Foram realizados experimentos para a comprovação da proposta apresentada, tendo-se obtido resultados bastante significativos.
Human Action Recognition with RGB-D Sensors

Human action recognition, also known as HAR, is at the foundation of many different applications related to behavioral analysis, surveillance, and safety, thus it has been a very active research area in the last years. The release of inexpensive RGB-D sensors fostered researchers working in this field because depth data simplify the processing of visual data that could be otherwise difficult using classic RGB devices. Furthermore, the availability of depth data allows to implement solutions that are unobtrusive and privacy preserving with respect to classic video-based analysis. In this scenario, the aim of this chapter is to review the most salient techniques for HAR based on depth signal processing, providing some details on a specific method based on temporal pyramid of key poses, evaluated on the well-known MSR Action3D dataset.
The influence of labour brokering practices on employment equity in South Africa: A case of two universities

The purpose of this paper is to highlight the influence of labour brokering on employment practices, particularly those related to the Employment Equity Act 55 of 1998. The research reported on in this paper is based on a larger research project that investigated the barriers to and enablers of gender equity within two higher education institutions. Utilising a qualitative case study at the two South African universities, the findings demonstrate the contradictions between the intentions of employment equity policies and practices and the adoption of a labour brokering employment strategy. Employment equity policies and practices did not include employees in the cleaning and gardening job categories recruited through labour brokers. Most importantly, the practice has serious implications for the economic survival and development of the lowest level of employees at the universities. The implications of these findings are discussed in the light of the Labour Relations Amendment Act 6 of 2014.
Oxidation effect on the mechanical behavior of thin samples of titanium alloy at 600 ° C

Titanium alloys offer a real opportunity for technological improvement for the aerospace industry. Their high mechanical properties, a level comparable to steel, coupled with a lower density condition the choice of titanium to lighten structures. Excellent corrosion resistance also allows a wide use in chemical plants. The literature shows several studies about the mechanical behavior of titanium alloys according to their surface, their thermo-mechanical treatments and their environment of use. The high reactivity of titanium with oxygen at high temperature not only leads to the formation of an oxide layer but also oxygen enrichment of the underlying metal. The effects of this change in chemical composition are important for the microstructure (-case). In this study, starting from samples of different thickness of commercially pure titanium, we focus on the mechanical behavior in tension and creep between 450 to 600 ° C. The originality of this study is to perform mechanical tests at high temperature on specimens thin enough to not be considered as homogeneous (substrate + -case + titanium oxide). These tests are correlated with microstructural analyzes carried out in order to interpret the influence of oxygen enrichment on the mechanical behavior of the alloy .
