Protective Effects of Vitamin C and Chitosan against Cadmium-Induced Oxidative Stress in the Liver of Common Carp (Cyprinuscarpio)

Background: Cadmium (Cd) intoxication can cause oxidative stress and involve the antioxidant defense system in hepatocytes. Administration of vitamin C, chitosan, or a combination of both may prevent Cd-induced oxidative damage. Methods:Cyprinus carpio were distributed into six groups. The control group received normal feed (Group I). Group II was exposed to 0.2 mg.L cadmium chloride. Group III were fed 1000 mg chitosan per 1 kg feed. Group IV was exposed to 0.2 mg.L cadmium chloride and fed with1000 mg chitosan per 1 kg feed while Group V was exposed to 0.2 mg.L cadmium chloride and was fed with 1000 mg vitamin C per 1 kg feed. Group VI, however, was exposed to 0.2 mg.L cadmium chloride and was fed with 1000 mg vitamin C combined with 1000 mg chitosanper 1 kg feed. After 21 days of experiment, activities of hepatic enzymes and oxidative stress biomarkers were evaluated. Results:Exposure to CdCl2 caused a significant increase in malondialdehyde levels and altered alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and lactate dehydrogenase activities in liver tissues. Hepatic antioxidant capacity, catalase, and Glucose-6phosphate dehydrogenase activities significantly decreased in fishes exposed to CdCL2 as compared to the control group. Treatment with vitamin C and vitamin C combined with chitosan significantly ameliorated these changes. Conclusion:The present findings suggest that the administration of chitosan failed to restore biochemical parameters to normal levels. However, these findings demonstrate that vitamin C and vitamin C combined with chitosan protect the fish against the toxic effects of CdCl2 on the examined biochemical parameters in liver tissues.
A Non-Artificial Setting Method for Fault Feeder Detection Systems Based on Data Fusion Used in Resonant Grounding Systems

Fault line detection timely and accurately when single-phase-to-earth fault occurs in resonant grounding system is still a focus of research. This paper presents a new approach for fault detection based on data fusion and it has non-artificial setting. Firstly, the fault criterion for interphase difference energy ratio and time-frequency correlation coefficient of each line is proposed. Subsequently, the paper establish a coordinate system with the interphase difference energy ratio as X axis and the time-frequency correlation coefficient as Y axis, and it uses the Euclidean distance algorithm to get the characteristic distance of each line by fusing two-dimensional information. Finally, comparing the sound distance and the fault distance of each line to discriminate the fault line. Electromagnetic Transients Program (EMTP) simulation results and adaptability analysis have confirmed the effectiveness and reliability of the proposed scheme.
The Politics of School-Based Management: Understanding the Process of Devolving Authority in Urban School Districts.

Since the late 1970s the problem of urban education has been cast as partially a problem of governance and authority structures. This focus mirrors a larger preoccupation by educational reformers with democratizing the decision-making process in public schools, a preoccupation that is evident not only in this country but also many nations throughout the world. Borrowing from the private sector, the underlying assumption behind decentralization is that educational improvement is only possible if those closest to the point at which decision are enacted become the architects of these decisions. Thus,
Characterization of Polyethersulfone/Cloisite 15A Mixed Matrix Membrane for CO2/CH4 Separation

Asymmetric hybrid organic-inorganic clay mineral polyethersulfone (PES) flat sheet membranes were prepared from solution containing Cloisite15A® (C15A) in the mixture of solvent and polymer. Neat PES and MMM were prepared through dry/wet phase inversion method. The newly developed membranes were characterized by means of SEM. The effect of filler addition, evaporation time and coating protocol towards the performance of the membrane was investigated. The measurement was carried out at room temperature and the upstream pressure was 3 bar while the downstream pressure was atmospheric. Experimental results showed that selectivity for MMM fabricated with 0.25 wt% clay loading at evaporation time of 40 s is lower compared to those prepared at higher evaporation time. After coating with silicone rubber solution and heat treated, the resultant membranes exhibited selectivity enhancement of CO2/CH4 from 7.9 to 28.4 for pristine PES, while PES/C15A1 and PES/C15A2 showed a selectivity improvement of 2.29 to 18.72 and 10.24 to 33.49 each. Optimum evaporation time and appropriate coating and heat treatment have significant contribution in developing high performance MMM for gas CO2/CH4 separation.
Cyclo-Static DataFlow Phases Scheduling Optimization for the Throughput Constrained Buffer Sizes Minimization Problem

Cyclo-Static DataFlow (CSDF) is a powerful model for the specification of DSP applications. However, as in any asynchronous model, the synchronization of the different communicating tasks (processes) is made through buffers that have to be sized such that timing constraints are met. In this paper, we want to determine buffer sizes such that the throughput constraint is satisfied. This problem has been proved to be of exponential complexity. Exact techniques to solve this problem are too time and/or space consuming because of the self-timed schedule needed to evaluate the maximum throughput. Therefore, a periodic schedule is used. Each CSDF actor is associated with a period that satisfies the throughput constraint and sufficient buffer sizes are derived in polynomial time. However, within a period, an actor phases can be scheduled in different manners which impacts the evaluation of sufficient buffer sizes. This paper presents a Min-Max Linear Program that derives an optimized periodic phases scheduling per CSDF actor in order to minimize buffer sizes. It is shown through an MP3 Playback and an H.263 Encoder that this Min-Max Linear Program allows to obtain close to optimal values while running in polynomial time. The impact of phases scheduling on periodic schedulability of applications with critical cycles is also highlighted on a Channel Equalizer.
EXTENDED HIGH RESOLUTION RANGE PROFILE- JET ENGINE MODULATION ANALYSIS WITH SIGNAL ECCENTRICITY

In this paper, high resolution range proflle-jet engine mod- ulation (HRRP-JEM) analysis is extended by including quantitative estimation of the jet engine location and extraction of the JEM micro- Doppler component. Based on a parametric model of the range cell data, signal eccentricity was introduced for the purpose of determining the jet engine location. Then, complex empirical mode decomposition (CEMD) was employed to extract the embedded JEM component. The signal eccentricity also served as an auxiliary means of CEMD-based micro-Doppler extraction. Application to the simulated HRRP-JEM data demonstrated that the analysis results described in this paper could be useful for advanced radar target recognition with HRRP- JEM.
POWER FLOW SOLUTION WITH FLEXIBLE AC TRANSMISSION SYSTEM DEVICES

Power flow analysis is the backbone of power system analysis and design. It is necessary for planning, operation, economic scheduling and exchange of power between utilities. This paper proposes load flow solution under steady state condition with flexible AC transmission system (FACTS) devices. FACTS technology opens up new opportunity for operation and control of power system. Out of the various FACTS devices Thyristor Controlled Series Capacitor (TCSC) and Unified Power Flow Controller (UPFC) are the right choices for the maximization of power flow in power system, which has been selected to control power flow in the transmission lines. TCSC is used to minimize active power losses and UPFC is minimizing both real and reactive power losses in the system. Test bus system is modeled and simulated using MATLAB (Power System Analysis Toolbox).
Baltic Europe – 40 years of integration

: Baltic Europe, i.e. the sea and inland hinterland, form a unique macro-regional unit. Strong collaboration links as well as competition in the Baltic Sea Region are an inherent feature of the region from the beginnings of its civilization development. The article shows the forty-year-long Baltic integra- tion process and the Polish scientific contribution to the process. Since 2004, the Baltic has become an internal EU sea. This fact no doubt strengthened cooperation of the countries around the Baltic Sea. In many spheres, these ties take the form of networking. An important stimulus for further integrations is the EU Strategy for the Baltic Sea Region. Political stabilisation and economic development may trans- form, in a longer time span, the emerging transnational Baltic Europe into a new economic and cultural European centre.
What You See Is not What You Get: Product Architecture and Corporate Strategy

Weaving insights from the study of technology, operations, and organizational theory, we examine factors that underlie decisions about product product architecture. The general principles that determine the composition and interdependency between the components that make a product have largely been relegated to the engineering literature. However, our preliminary results from a Wharton-SMU study of product architecture in the imagining industry suggest several overlooked factors that play an important role in determining product architecture and consequently – firm performance. We suggest that product architecture decisions are far from being the exclusive domain of engineers. Using a sample of firms and products from the imaging sector, we distinguish between the engineering product architecture and perceived product architecture and note that they can be decoupled. Second, we seek to determine how firm choices regarding the design architecture can be mapped explained using variables such as firm prestige and customer sophistication.
CO-SOURCING DEVELOPMENT OF ACCELERATOR CONTROLS

Frequently, accelerator facilities make use of products and services offered by the industry. This paper’s focus is on such outsourcing of control system hardware and software. Firstly, an attempt is made to explain the facility’s motivation for seeking outside help, which is typically due to lack of resources, technology or knowledge. Then, the risks of outsourcing are enumerated. To mitigate them, the industrial partner should have not only the adequate technical expertise, but also a reliable, yet agile management and quality assurance process that meets the facility’s expectations, schedule, budget constraints, maintenance and support needs. Finally, Cosylab’s business model is presented, designed to provide lasting open-source solutions that help not only a single facility, but the entire community.
Open Innovation: The New Way of Knowledge Transfer?

Due to globalization, competition has increased and companies have reorganized their activities in order to maintain profitability. The consequence has been an emphasis on short term results, at the expense of long term research. Therefore, most Corporate Research laboratories were closed or built down considerably. However, long term research is required for products that are difficult to copy by competitors. Moreover, companies have come to realize that only radical innovation, based on long term research, will distinguish them from their competitors. Since the end of the 1990s, attempts are being made to combine short term financial interests with long term innovation requirements. Many of these attempts can be classified under the heading of Open Innovation, which may be viewed as a company’s endeavour to profit from external knowledge without making heavy internal investment in long term research. This paper examines the prospects of Open Innovation, on the basis of own research and reported literature work. It is argued that companies cannot totally rely on external sources of knowledge, and that new ways must be found to compensate for the results that used to be achieved by companies’ own Corporate Research.
Damping identification for the nonlinear stiffness structure

The classical time domain and frequency domain methods of damping identification are not be suitable to the structures with nonlinear stiffness. Therefore, on the basis of modifying the classical half-power bandwidth method, this study presented a method to identify the damping of nonlinear stiffness structure. Based on the movement equation of structure, the identifying damping formulas were derived respectively for the structure with weak and strong stiffness nonlinearity. Furthermore, the correctness of the proposed formulas was verified with a numerical simulation example. Then, the test damping procedure was proposed for the above mentioned nonlinear stiffness system. At last, this procedure has been demonstrated using a hard coating specimen with soft nonlinearity and the damping parameters of structure were obtained under different exciting levels.
Socialization for the Knowledge Society.

The purpose of the study is to give an overview and present special features of socialization of the research type that prepares young people for life in the knowledge society. Methods of cultural and historical epistemology, of hermeneutic and structural-functional analysis of social action have been used in the study, as well as elements of the theory of values and philosophic ontology. The experimental part of the study involves methods of comparative analysis and synthesis of social work with creatively active schoolchildren and students. The article analyses the role of education in the conception of the knowledge society, created in the period 1940-1960s. As fundamental factors of a new type of socialization, the cognitive role structure of the knowledge society and spiritual abilities determining creativity are presented. The possibility of early research socialization is explained through the dynamics of the professional maturation period in the conditions of the general technological field of modern knowledge culture. The article lays a theoretical foundation and provides practical justification for a new socialization of the research type, which plays a crucial role in the development of the knowledge society and interprets the content of modern education according to its cultural mission.
Prenatal Genetic Diagnosis Using Transcervically Derived and Immunomagnetically Isolated Trophoblast Cells

Trophoblast cells migrate from the placenta into the endocervical canal early in the first trimester and can be collected non-invasively by transcervical sampling (TCS), potentially providing fetal DNA for prenatal genetic diagnosis. Experiments were conducted to separate fetal cells from maternal cells within the TCS specimens and use the fetal cells to perform genetic analysis. Trophoblast cells were efficiently isolated from TCS specimens during weeks 5-18 of gestation using HLA-G antibody coupled to magnetic nanoparticles. Immunofluorescence microscopy revealed that 99% of isolated cells expressed the chorionic gonadotropin β subunit (β-CG), while the non-bound cell fraction expressed none. Immunomagnetically isolated cells from 20 patient specimens
Application of Adaptive Processing Technique for the Inversion of Open Hole Logs Recorded in Oil Fields of Indian Basins

Summary Adaptive Processing Technique for comprehensive well log evaluation solves the simultaneous system of logging tool response equations through statistical approach by using weighted least square minimization technique. It involves minimization of the i ncoherence function i.e. summation of square of errors between the measured and constructed logs by incorporating the total uncertainties on tools, parameters and response equations. It also simultaneously optimizes the unknowns and zones parameters in different way. It intr oduces the statistical theory that least square estimates are the mean estimates and only mean values are optimized while selecting minera ls parameters for a particular zone. Process is adaptive in the sense that it uses the results of previous stage/level as the input to the ne xt stage/level. Adaptive Processing Technique has been successfully in use for comprehensive well log evaluation of all type of reservoirs of Indian Basins. Siliciclastics complex reservoirs of Upper Assam, Krishna Godavary and Kavery Basins, Western on Shore and offsh ore, fractured and non fractured carbonates reservoirs of Mumbai High have been processed with this package. Evolution of basic conc ept of inversion of open hole logs through weighted least square technique and how basic conditions, which ensures the mathematical fe asible solutions for the log evaluation problem, are linked through parameter selection on cross plots are illustrated with actual fi eld examples. Selection of parameters on cross plots which ensures feasibility of the mathematical solutions and minimum value of incoherence /error function are essential for the successful application of the package. The log analyst has to achieve the meaningful results by fine-tuning the parameters within the uncertainties defined on the log measurements. An improper parameter selection can produce a meaningless paralogs, which may not corroborate at all with the geological model/ reservoir characteristics of the field.
Title IX Coordinators in Dual Roles: Challenges, Experiences, and Sources of Support

This article explains a portion of a study that was conducted to examine the experiences and challenges that Title IX Coordinators face at small and medium-sized, private institutions. Through the use of an online questionnaire and semi-structured interviews with Title IX Coordinators, this study explored the specific challenges they face in their positions, especially if they have another full-time role at their institution. Title IX Coordinators face great challenges in their roles, such as lack of time and financial resources, difficulty setting up a solid infrastructure, and highly emotional topics and decisions. The issues created by a lack of intersectionality of their dual roles, as well as implications for Title IX administrators and recommendations, are discussed.
Formaldehyde and nitrogen dioxide over the remote western Pacific Ocean: SCIAMACHY and GOME-2 validation using ship-based MAX-DOAS observations

Abstract. In October 2009, shipborne Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements were performed during the TransBrom campaign over the western Pacific Ocean (≈ 40° N to 20° S). Vertical tropospheric trace gas columns and profiles of nitrogen dioxide (NO2) and formaldehyde (HCHO) as well as stratospheric NO2 columns were retrieved in order to validate corresponding measurements from the GOME-2 and SCIAMACHY satellite instruments and to estimate tropospheric background concentrations of these trace gases. All instruments reproduced the same characteristic, latitude-dependent shape of stratospheric NO2. SCIAMACHY and GOME-2 data differ by about 1% from each other while yielding lower vertical columns than MAX-DOAS morning values as a consequence of measurement time and stratospheric NO2 diurnal cycle. Due to this diurnal cycle, an increase of 8.7 ± 0.5 × 1013 molec cm−2 h−1 of stratospheric NO2 was estimated from MAX-DOAS data at low latitudes during the day. Tropospheric NO2 was above the detection limit only in regions of higher anthropogenic impact (ship traffic, transport of pollution from land). A background column of 1.3 × 1014 molec cm−2 (or roughly 50 ppt boundary layer concentration) can be estimated as upper limit for the remote ocean, which is in agreement with GOME-2 monthly mean values. In the marine boundary layer close to the islands of Hokkaido and Honshu, up to 0.8 ppbv were retrieved close to the surface. Background HCHO concentrations over the remote ocean exhibit a diurnal cycle with maximum values (depending strongly on weather conditions) of 4 × 1015 molec cm−2 for the vertical column at noontime. Corresponding peak concentrations of up to 1.1 ppbv were retrieved in elevated altitudes (≈ 400 m) around noon while maximum concentrations in the evening are close to the ground. An agreement between MAX-DOAS and GOME-2 data was found for typical vertical columns of 3 × 1015 molec cm−2 over the remote ocean at the time of overpass.
Methanotrophs: The Natural Way to Tackle Greenhouse Effect

Methane is considered as an important greenhouse gas which produced from a wide range of anthropogenic and natural sources. It plays a key role in global warming. Capturing and disposal of methane is technically both costly and problematic. A low-cost alternate to the conventional methods is the microbial oxidation of methane. Methanotrophs are the type of bacteria that aerobically oxidize methane as a source of energy through their key enzyme, monooxygenase (MMO), especially the soluble MMO, it is noteworthy in its broad substrate specificity. This exceptional capability, i.e., catalyzing reactions of environmental importance, has owned methanotrophs attention from applied microbiologists and biotechnologist. From about 30 years, it is observed that copper (Cu) is playing an important role in the physiology and activity of methanotrophs, but the discovery of how Cu collect by these cells, more importantly what is the role Cu playing in CH4 oxidation by the particulate CH4 monooxygenase and how Cu affects the ability of methanotrophs to oxidize different substrates has been made. In this review we summarize the morphology, phylogeny, ecology, and possible applications of methanotrophs to address the global as well as regional issues, along with the role of gene expression regulation by Cu and how it affects the cell activity of methane-oxidizing bacteria. Our focus was on two main aspects of potential value and application of methanotrophs in environmental bioremediation, namely physiology along with working of methanotrophs and methane removal from atmosphere.
Comparative analysis of antioxidant capacity of wheat (Triticum aestivum L.) at different temperatures in polytunnel

The present investigation was aimed to study the effect of high temperature (HT) stress on antioxidant defense system in two wheat (Triticum aestivum L.) cultivars raised in polytunnel house fitted with five sensors maintained at different temperatures. Various sensors were tuned to temperature of +3.0 ̊C (S1), +3.2 ̊C (S2), +3.3 ̊C (S3), +3.5 ̊C (S4), +3.6 ̊C (S5), above the ambient temperatures of 20 ̊C (flag leaf, 90 days after sowing; DAS) and 22 ̊C (grains, 15 and 30 days post anthesis; DPA). Various biochemical and morphophysiological parameters were recorded in flag leaf and grains in two wheat cultivars HD 2967 (heat tolerant) and PBW 702 (heat sensitive) at different stages of grain development. Plant growth was largely depressed due to HT which resulted in disruption of cellular membrane by increasing membrane injury index, lipid peroxide and H2O2 contents. High temperature stress caused significant increase in activity of enzymatic and non-enzymatic antioxidant such as superoxide dismutase, glutathione reductase, catalase, ascorbate peroxidase and contents of proline, ascorbic acid, glutathione and H2O2 in flag leaf (90 DAS) and developing grains (15 and 30 DPA). Maximum increase in antioxidant enzymes was observed in heat tolerant cv. HD 2967 at S5 (+3.6 ̊C) sensor. Apparently, heat tolerant cultivar HD 2967 possessed lower content of lipid peroxide and chlorophyll of owing to better expression of antioxidant system. Increasing temperature above ambient in the tunnel caused a marked increase in relative membrane injury and H2O2 contents and rise in these attributes caused significant membrane injury in PBW 702. Taken overall, the performance of cultivar HD 2967 was better over PBW 702 in terms of lesser oxidative damage and greater cellular levels of ascorbate, glutathione and proline.
