Properties of a-Si:N:H films beneficial for silicon solar cells applications
Authors: Swatowska B. , Stapiński T. , Zimowski S. 
Published: March 2012

AbstractAmorphous silicon-nitride thin films a-Si:N:H were obtained by plasma enhanced chemical vapour deposition (PECVD) method from SiH4+NH3 at 13.56 MHz. The process parameters were chosen to obtain the films of properties suitable for optoelectronic and mechanical applications. FTIR analysis of a-Si:N:H films indicated the presence of numerous hydrogen bonds (Si-H and N-H) which passivate structural defects in multicrystalline silicon and react with impurities. The morpho-logical investigations show that the films are homogeneous. The deposition of a-Si:N:H layers leads to the decrease in friction coefficient of used substrates. Optical properties were optimised to obtain the films of low effective reflectivity, large energy gap Eg from 2.4 to 2.9 eV and refractive index in the range of 1.9 to 2.2. Reduction of friction coefficient for monocrystalline silicon after covering with a-Si:N:H films was observed: from 0.25 to 0.18 for 500 cycles.
Construction of Master Recession Curve Using Genetic Algorithms
Authors: Gregor Miloš , Malík Peter 
Published: March 2012

Construction of Master Recession Curve Using Genetic AlgorithmsThe article describes a new methodology of using genetic algorithms to assemble a natural time series of discharge recession, from which a master recession curve can be interpreted both for streams and for springs. Presented approach can avoid obstacles such as limited time-series datasets, incomplete recessions or too many recessionary segments in many recession series, different time intervals of observations (daily or weekly frequencies). Short time-series intervals, imprecise or mistaken measurements and different types of datasets (averaged or directly measured data) are taken into account as well. Even rough measurements of discharges with inaccurate sensing range can be analysed, if sufficiently long observation is available. Complicated hydrograph shapes in the case of e.g. karstic springs (often caused by combination of laminar and turbulent discharge sub-regimes due to karst network settings) can be processed as well. Subsequent construction of master recession curve is much easier an offers better conditions for its interpretation. Presented algorithm was already implemented to a programme solution, completed on the user form.

Linkage Between In-Stream Total Phosphorus and Land Cover in Chugoku District, Japan: An Ann ApproachDevelopment of any area often leads to more intensive land use and increase in the generation of pollutants. Modeling these changes is critical to evaluate emerging changes in land use and their effect on stream water quality. The objective of this study was to assess the impact of spatial patterns in land use and population density on the water quality of streams, in case of data scarcity, in the Chugoku district of Japan. The study employed artificial neural network (ANN) technique to assess the relationship between the total phosphorous (TP) in river water and the land use in 21 river basins in the district, and the model was able to reasonably estimate the TP in the stream water. Uncertainty analysis of ANN estimates was performed using the Monte Carlo framework, and the results indicated that the ANN model predictions are statistically similar to the characteristics of the measured TP values. It was observed that any reduction in forested area or increase in agricultural land in the watersheds may cause the increase of TP concentration in the stream. Therefore, appropriate watershed management practices should be followed before making any land use change in the Chugoku district.

Remote-Sensing Based Groundwater Recharge Estimates in the Danube-Tisza Sand Plateau Region of HungaryMean annual recharge in the Danube-Tisza sand plateau region of Hungary over the 2000-2008 period was estimated at a 1-km spatial resolution as the difference of mean annual precipitation (P) and evapotranspiration (ET). TheETrates were derived from linear transformations of the MODIS daytime land surface temperature (Ts) values with the help of ancillary atmospheric data (air temperature, humidity, and sunshine duration). The groundwater under the sand plateau receives about 75 ± 50 mm of recharge annually (the plus/minus value is the associated error, resulting from an assumed 5% error in both thePandETvalues), which is about 14 ± 9 % of the regional mean annualPvalue of 550 mm. The largest continuous region with elevated recharge rates (about 180 ± 50 mm a-1or 30 ± 8 % ofP) occur in the south-western part of the plateau due to more abundant precipitation (around 580 mm a-1), while recharge is the smallest (about 40 ± 40 mm a-1or 7 ± 7 % ofP) under forested areas. Typically, lakes, wetlands, river valleys, and certain afforested areas in the north-central part of the region act as discharge areas for groundwater.

Method of convective velocity determination from dissipative range of energy spectrum
In the study a new proposal of convective velocity determination necessary for eddy size determination from the dissipative range in a turbulent flow in a mixer was made. The proposed quantity depends on all the mean and fluctuating velocity components. By applying convective velocity one may determine the distribution of time and linear Taylor microscale in a stirred vessel.

Effective diffusivity of moisture in low rank coal during superheated steam drying at atmospheric pressureThe effective diffusivity of water in brown coal of Bełchatów mine was experimentally determined. The experiments were performed in superheated steam at 200°C and atmospheric pressure using slightly compressed pellets of cylindrical shape. The drying and temperature curves of the sample were used to identify diffusivity. An inverse problem was formulated and solved by the finite element method for 3D axially symmetric cylindrical geometry of the sample. A satisfactory fit of the simulated curves to experimental results was obtained. The obtained dependence of effective diffusivity on moisture content and temperature may be used in designing lignite dryers.

Comparison of experimental data and numerical simulation of two-phase flow pattern in vertical minichannel
The aim of the study was the implementation of a numerical simulation of the air-water two-phase flow in the minichannel and comparing results obtained with the values obtained experimentally. To perform the numerical simulations commercial software ANSYS FLUENT 12 was used. The first step of the study was to reproduce the actual research installation as a three-dimensional model with appropriate and possible simplifications - future computational domain. The next step was discretisation of the computational domain and determination of the types of boundary conditions. ANSYS FLUENT 12 has three built-in basic models with which a two-phase flow can be described. However, in this work Volume-of-Fluid (VOF) model was selected as it meets the established requirements of research. Preliminary calculations were performed for a simplified geometry. The calculations were later verified whether or not the simplifications of geometry were chosen correctly and if they affected the calculation. The next stage was validation of the chosen model. After positive verification, a series of calculations was performed, in which the boundary conditions were the same as the starting conditions in laboratory experiments. A satisfactory description of the experimental data accuracy was attained.

The Fractional derivative rheological model and the linear viscoelastic behavior of hydrocolloids
This study was aimed at evaluating the possibility to use the Friedrich-Braun fractional derivative rheological model to assess the viscoelastic properties of xanthan gum with rice starch and sweet potato starch. The Friedrich-Braun fractional derivative rheological model allows to describe viscoelastic properties comprehensively, starting from the behaviour characteristic of purely viscous fluids to the behaviour corresponding to elastic solids. The Friedrich-Braun fractional derivative rheological model has one more virtue which distinguishes it from other models, it allows to determine the relationship between stress and strain and the impact of each of them on viscoelastic properties on the tested material. An analysis of the data described using the Friedrich-Braun fractional derivative rheological model allows to state that all the tested mixtures of starch with xanthan gum form macromolecular gels exhibiting behaviour typical of viscoelastic quasi-solid bodies. The Friedrich-Braun fractional derivative rheological model and 8 rheological parameters of this model allow to determine changes in the structure of the examined starch - xanthan gum mixtures. Similarly important is the possibility to find out the trend and changes going on in this structure as well as their causes.
The Experience the Gift in a Model of Co-Therapy
Authors: Canna Paola , Partinico Manuela 
Published: March 2012

Abstract
The significant social and cultural transformations which took place in recent decades brought about significant changes in the way couples interact and deal with “the risk of bonding”. The vulnerability that characterizes the couple in post-modernity is the consequence of these changes. The application of a co-therapy model with couples in crisis is based on the premise of mutual gift, which has to be understood as both an exchange of expertise and professionalism to the benefit of the couple, and as a bond of unity between co-therapists. The work that follows suggests some reflections which originate from the co-therapy model.
The novelty of this model originates from the fact that the clinical work is based on two connected and complementary aspects: a deep attention towards the patient and a deep attention towards the relationship between the co-therapists. Both of these aspects are characterized by the dimension of gift.
In this clinical model therapists transform any specific suffering lived by the couple in a positive relational experience between themselves which then becomes an example for the couple. Thus, for example, the inability to understand each other that the couple lives is contrasted by the capacity to listen to each other in a deep and authentic way by the therapists; the attitude of prevailing over each other in the couple, is counterbalanced by the therapists’ attention towards each other. And so on. This act of “overturning the limit” seems to reveal the therapeutic potential that a model of co-therapy, based on a new humanism, can offer to the clinical work with couples in crisis.
Emergence
Authors: Raven John 
Published: March 2012

Abstract
In this paper I first list a number of areas in which recent research seems to reinforce the need to follow through on activities identified in Simonetta Magari’s article (Magari, Cavaleri 2009). A careful review of research in these areas would lead us into deeply mysterious psychological processes and underline the need to change the most fundamental assumptions on which modern psychology is built. Unfortunately, I am in no position to undertake this review.
Accordingly, I have settled for the lesser objective of discussing (i) the problems posed by the phenomenon of emergence; (ii) the dominant role that networks of external social forces play in determining behaviour (and the way these networks of social forces perpetuate and elaborate themselves), and (iii) the emergence of a network of negative social forces which seems to have the future of mankind and the planet in its grip.
I start by showing that one of the most important uses of the slippery word “intelligence” is to refer to an emergent property of a group. Groups can, to a greater or lesser extent, harness (or neglect and destroy) the diverse talents available to them to create cultures of intelligence or enterprise on the one hand and despondency and conflict on the other.
Whereas we, as a species, currently have the highest levels of individual intelligence ever, it seems that we have the lowest levels of collective intelligence ever.
But group and individual characteristics are not the only things transformed by networks of social forces. Time after time we see that well intentioned social action is transformed into its opposite by networks of social forces.
A systemogram of the social forces which transform the “educational” system into its opposite is then used as a basis for a discussion of the role of social forces more generally.
Two issues then stare one in the face. One is that our governance systems are ill equipped to promoting the kind of experimentation and societal learning that is needed…especially to enable us to survive as a species. The other is the dominance of the “sociological” forces pressing unrelentingly toward the societal hierarchy and division that is leading us so forcefully toward our self-destruction.
Unexpectedly, therefore, it emerges that two key tasks for psychologists, qua psychologists, are (i) to contribute to the design of a societal management system which will act more effectively in the long term public interest – that is to say, in the interests of maintaining life itself – and (ii) to map the network of social forces which are driving us so relentlessly toward our own extinction.
The Way We Are Together Today: Identity and Relationships in Contemporary Societies
Authors: Menditto Maria 
Published: March 2012

Abstract
The last century has catapulted us into a world full of instability, uncertainty, and a sense of bewilderment.
The financial-economic crisis has been added to our difficulties, further polluting our environment, our relationships, our feelings, our wounds. Pre-cariousness, lack of work and of a vision for the future have been added to our sense of emptiness and disorientation. Hope has given way to darkness. We are immersed in the crisis. The feeling of tranquillity and security that we desire is fading, far away, and even forgotten. We are poised upon unstable ground, which makes us tremble and amplifies our need for stability and support. The single person favours self control and mastery, retiring narcissistically into him or herself and refusing help from anyone, not accepting any kind of wound or fragility.
Behind these widespread attitudes lies the myth of total independence and of self sufficiency.
Psychological and psychotherapeutic disciplines bring a change, within this context, towards a “relational turning point”, discovering in the dynamics of reciprocity the source of individual wellbeing, balance in relationships, and a sense of belonging to a community. The connection with another person makes it possible to build up a sense of oneself where multiplicity and unity, difference and belonging, individual and community coexist. Individuality and belonging are no longer opposed to one another, causing irresolvable conflict in the development of the self, but thanks to reciprocity, to the capacity of self giving and to ethics, they can be fully integrated and contribute to the daily activities, both in the individual and collective dimension, of each person.
The Mediating Role of Well-Being and Self-Regulation of Emotions in Daily Executive Dysfunctions and Psychological Distress

Published: March 2012

Abstract
An emerging literature has begun to document the emotional consequences of everyday executive functions on emotional distress. Little is known, however, about whether this relation is mediated by other variables.
A multiple mediation model was proposed to integrate core concepts of daily executive dysfunctions with emotional distress in order to increase understanding of their relationship to psychological well-being and emotional regulation. The working hypothesis was that dimensions of well-being and emotional regulation may be a suitable mediator. It was hypothesized that dimensions of well-being and emotional regulation are a possible mediator between the executive dysfunctions and psychological distress. Participants were 122 undergraduate students from university courses in General Education and Social Education at, the Universidad Complutense de Madrid, with a mean age of 21.76. Results indicate that several dimensions of psychological well-being and emotional reappraisal strategies mediate the relationships between daily executive dysfunctions and psychological distress. Implications of these data are discussed.

The present study was carried out on the seasonal abundance and diversity of zooplankton in a semi- intensive shrimp farm of Bagerhat district from June to December, 2008. Plankton samples were collected by conical shaped monofilament nylon net (Plankton net) and Lugol’s solution was used for preservation. The zooplankton abundance was influenced by physico-chemical factors. In the present study 5 groups of zooplankton were observed namely rotifer, copepod, cladocera, ostracoda and crustacean larvae. Among the various groups of zooplankton, the percentages of copepod, rotifer, cladocera, ostracoda and crustacean larvae in the culture system were 52%, 39%, 7%, 1% and 1% respectively. The zooplankton was dominated by copepods (52%) which showed more or less two peaks in August (833 individuals/L) and in October (815 individuals/L). Rotifer and copepod were about r awhile one genus Cypris of ostracod was found only in August. Three genus of copepod namely Diaptomus, Cyclops and Mesocyclops were identified in the study area of which Diaptomus and Mesocyclops were more or less dominant while four genus of which Brachionus and Filinia under rotifer and Daphnia and Diaphanosoma under cladocera were also found during the study period. The findings of the present study will help to improve the management strategies of shrimp culture system.DOI: http://dx.doi.org/10.3126/ijls.v5i1.5286 International Journal of Life Sciences Vol.5(1) 2011 1-11
Protective Effects of Embelin and Curcumin against Diethylnitrosamine / Phenobarbital induced Experimental Hepatocarcinogenesis in Rats
Authors: Jagadeesh MC , Sreepriya M , Bali Geetha , Manjulakumari D 
Published: March 2012

The effects of administration of Curcumin and Embelin on the levels of certain trace elements and other elements of clinical significance, during experimental hepatocarcinogenesis induced by Diethylnitrosamine/ Phenobarbital (DENA/PB) was studied in Wistar strain male albino rats. The levels of calcium, potassium and sodium were determined in the serum of control and experimental groups of rats. Additionally, the levels of chromium, copper, magnesium, molybdenum and zinc were also determined in the serum, liver and kidney of these rats. Furthermore, lactate dehydrogenase (LDH) activity was also assayed in the serum of these rats. Results revealed both significant and non-significant alterations in the levels of few elements during DENA/PB-induced experimental hepatocarcinogenesis. A statistically significant increase in LDH activity was found in the serum during the cancerous condition. Pre- and co-treatment with Curcumin and Embelin was found to protect the liver against the carcinogenic effects of DENA/PB. This protection was i) due to their ability to prevent changes in the levels of elements studied and ii) by the statistically significant decrease in the activity of LDH that increased in DENA/PB-treated rats and LDH activity in the rats given only Embelin and Curcumin indicating their non-toxic effect. Our present results demonstrate the ability of Embelin and Curcumin to protect against DENA/PB-induced hepatocarcinogenesis in rats.DOI: http://dx.doi.org/10.3126/ijls.v5i1.5576 International Journal of Life Sciences Vol.5(1) 2011 51-56
