Studies revealed that the maximum profit from fish production can be achieved by adoption of proper recommended technology. Extent of adoption of the recommended fish production technology is one of the main reason contributing to low fish production. To improve the adoption of fish production technology, it is necessary to assess its level existing at actual situation. The perusal of data "overall average adoption of fish technology" revealed that out of the total fish farmers, the highest proportion of the fish farmers 36.67 per cent have adopted medium level of "overall average adoption of fish technology" technology before FLD's followed by low adoption 35.00 per cent and high adoption 28.33 per cent of "overall average adoption of fish technology" technology before FLD's respectively.

In the era of big data, the integration of online teaching resources of university ideological and political theory courses is confronted with challenges' of large amount of data, diversity and the hide of the value. To take the opportunity and meet the challenges, we should clarify the connotation and components of the integration of online teaching resources of university ideological and political theory courses, following three integration principles. The guideline for the integration of online teaching resources of university ideological and political theory courses lies in integrating three different levels of teaching objectives: competence, knowledge and quality into three corresponding resource modules to enrich online teaching resources, so as to improve the effects of university ideological and political theory courses online teaching.

Business English Course helps students develop international business theory ability for English majors, which can lay a good foundation for their future employment. "Normal" English curriculum is abundant in current talent training scheme for English Major of local Normal Universities. But some "non-normal" English Curriculum (such as business English) is set up seldom, which is unfavorable to the cultivation of the talents who adapt to today's society........

In Mediterranean countries to semi-arid climate like Morocco, the phenomenon of eutrophication of water bodies is posed with great acuity. The enrichment of water of retaining dam by nutrients, especially phosphorus compounds causing an accelerated growth of algae and higher forms of plant. This development leads to an undesirable disturbance to the equilibrium of organisms present in the water and leads a degradation of the water quality. So it seems particularly useful to seek to determine the various forms of phosphorus bound to sediment and of evaluate in particular the contents of bioavailable forms...........

The present study aims to investigate by experiment the heat transfer characteristics of a mild steel plate by using three different shapes of Wall Jet, namely, Circular Jet, Elliptical Jet and Rectangular (Plane) Jet. It is found that Nusselt Number (Nu) increases up to Reynolds Number (Re) 14000and its rate of increasing is in the order of Circular>Elliptical>Rectangular. While Re>14000, rate of increasingNu becomes in the order of Elliptical>Circular>Rectangular.Pressure Co-efficient (Cp) decreaseslogarithmically for any value of Re.It is observed that for a fixed value of span-wise distance like 10.67cm,Cpfor Circular, Elliptical and Rectangular Wall Jetsare consecutively 0.074278, 0.02678 and 0.018569.If Cp decreases rapidly, heat transfer rate will decreases rapidly. Hence,cooling rate for Wall Jet flow follows the prescribed order ofCircular>Elliptical>Rectangular at low Re and Elliptical> Circular> Rectangular at high Re.

The liability of the face recognition systems in the biometrics is a growing concern today, as still it remains vulnerable to the various sophisticated attacks that in determined the reliability of biometric systems. In this paper, we present a novel approach which accurately detects and mitigates the spoof attacks on the face by introducing a new Lytro called light field camera (LFC), also known as Plenoptic camera. LFC can records the multi dimensional data and also capture information about the light field emanating from the scene: i.e., the intensity of the light as well as the direction that the light rays were traveling in the space............

Today's requirement of multichannel audio system can be full filled by using the TAS5508 eight channel digital pulse width modulator which provides both advanced performance & a high level of system integration. Multichannel audio system using PWM based open-loop digital class-d audio power amplifier pusses a fundamental problem of inherent nonlinearity of PWM process. This can be overcome by using a high performance digital power amplifier TAS5121 from Texas instruments incorporate in.

A fast matchedfilter reconstruction technique for ground penetrating radar (GPR) tomography is proposed for generating 2D images of buried objects with signal processing techniques to calibrate GPR data. Reconstruction of a 2D image from these data is achieved with numerical discretization and matched-filter techniques. This requires less computational power and is simpler to implement relative to matrix inversion or other inversion methods. The primary benefits, as compared to other GPR imaging methods, are improved resolution and 2D imaging for easy survey analysis..............

This paper addresses a unique method of ISAR dipole model image by employing vector dyadic contrast function technique. The current ISAR imaging algorithms rely upon the assumption that the area under investigation consists of a superposition of infinitesimally small isotropic scatterers (i.e., the point scatterer model). This approximation fails to capture the true real-world scattering mechanisms occurring within the targets of interest. Therefore, this paper proposes a batter imaging technique which based upon the assumption that targets can be modeled as a collection of infinitesimally small dipoles. The orientation of each dipole is accounted in a dyadic contrast function. The image reconstruction, i.e., retrieval of the dyadic reflectivity function from measured data, will not only provide information regarding the shape but also the direction of predominant edges of the target.
