A responsibility of knowledge management in HRM
Man’s relentless quest for knowledge and its documentation have had profound impact on development of human race at every stage. The fast change in the quality of our lives over the centuries has been because of the knowledge flow in the information technology age of today. On a global basis, organizations are recognizing the importance of knowledge as a means to gain or sustain competitive advantage. Researchers have concluded that the only thing that is sustainable, for successful businesses, in the New Millennium – is what it knows, how it uses what it knows, and how fast it can know something new. In the past, the dilemma was finding enough information, but now the problem has shifted to identifying and managing the nuggets of mission-critical knowledge amongst the mountains of meaningless noise. Many organizations are primarily knowledge-focused. They obtain data and information and produce either a product or service. In this production process they use their own, and others, knowledge and information. Much of the knowledge in an enterprise is grounded in the minds of employees. The awareness of the value of knowledge to a business, coupled with its management, acts as an integrator that improves cross-functional communication and cooperation. Shared knowledge not only makes for a more effective, efficient and agile organization, but creates a common perspective and culture that produces a natural consistency of successful decisions and actions.

An impact of TCPS with LFC in an multi area power system using conventional controllers
The main objective of Load Frequency Control (LFC) is to regulate the power output of electric generator within an area, in response to the changes in system frequency and tie-line loading. Thus, LFC helps in maintaining the scheduled system frequency and tie-line power interchange with other areas within the prescribed limits. Most LFCs are primarily composed of an integral and PID controller. The integrator gain is set to a level that compromises between fast transient recovery and low overshoot in the dynamic response of the overall system. This type of controller is slow and does not allow the controller designer to consider the possible changes in operating condition and non-linearity in the generator unit. Moreover, it lacks in robustness. FACTS are designed to overcome the limitations of present non-reheat thermal-thermal power systems and enhance the power system stability. One of the promising FACTS devices is the Thyristor controlled phase shifter (TCPS) to alleviate this difficulty. TCPS is connected in the tie-line to self-tune the parameters of integral and PID controller. Two area system, have been considered for simulationof the proposed TCPS connected integral and PID controller .The performance of the Conventional controller, TCPS connected Integral and PID controller have beenCompared through MATLAB Simulation. The qualitative and quantitative comparisonshave been carried out for Integral, PID controllers. The dynamic of performance responses of Integral and PID controller with TCPS shows that in terms of settling .Time, peak overshoot and steady state error are greatly improved than that of without TCPS.

Analysis of Selected Metals in Edible Fish and Bottom Sediment from Lake Hawassa, Ethiopia
Sediment and fish (nile Tilapia, Oreochromis niloticus) were collected from six sites of Lake Hawassa namely; Tikur Wuha, Amora Gedel, Dorie Bafana, Central part of the lake, the opposite side of Amora Gedel and Referral Hospital sites. Concentration of heavy metals was analyzed quantitatively using Flame Atomic Absorption Spectrophotometer and Chemometric methods. The maximum and minimum mean levels (mg/kg dry mass) in different lake sediment sites were Cu (51.38-17.64), Mn (348.51-140.63), Cd (12.8764-403), Pb (30.05-6.72), Ni (26.73-8.43 ), Zn (367.84-147.49), Cr (14.15-5.34), Co (27.19-9.59 ), Mg (3859.86-1872.43), Na (4913.72-2903.043), Ca (5526.74 - 3608.71), K (4229.69-2255.57) and that of fish muscle were Cu (13.833-5.666), Mn (11.972-9.722), Zn (21.110-12.055), Ca (574-482), Mg (512-437), Na (771-681), K (903-785). The result shows that the metal concentration in sediment samples is in order of Ca > Na > K > Mg > Zn > Mn > Cu > Pb > Co > Ni > Cr > Cd. The detectable metals in Tilapia fish muscle were in order of K > Na > Ca > Mg > Zn > Mn > Cu. In all the samples, concentrations of metals in sediment samples were higher than those of fish samples.

Application Groupoids in the algebra
A groupoid is medial if it satis_es the identity wx • yz = wy • xz. A groupoid is trimedial if every subgroupoid generated by 3 elements is medial. Medial groupoids and quasigroups have also been called abelian, entropic, and other names, while trimedial quasigroups have also been called triabelian, terentropic, etc. (See [5], especially p. 120, for further background). The notion of variety of algebras having the property (k, n) was given in [6] and equationally defined classes of cancellative groupoids having the property (2, 4) and (2, 5) were considered there. This notion was qeneralized in [7], where it was shown that the condition of the cancellativity is superfluous, that is, any variety of groupoids with the property (2, n) is a variety of quasigroups. Let k and n be two positive integers and k n. An algebra A is said to have the property (k, n) if every subalgebra of A generated by k distinct elements has exactly n elements. We also say that A is a (k, n)-algebra. A class K of algebras is said to be a (k, n)-class if every algebra in K is a (k, n)-algebra. A variety is called a (k, n)-variety if it is a (k, n)-class of algebras. Trivially, the variety of Steiner quasigroups (xx = x, xy = yx, x•xy = y) is a (2, 3)-variety. It is the unique variety of groupoids with the stated property, and the same holds for the (2, 4)-variety (x•xy = yx, xy•yx = x) given by Padmanabhan in [6]. He has also constructed two (2, 5)-varieties. One of them is commutative (xy = yx, x(y•xy) = y, x(x•xy) = y•xy), while the other one (x•xy = y, xy•y = yx) consists of anticommutative quasigroups. It is an verify the existence of (2, n)-varieties for n?10

Application specific NOC: power optimization by custom topology generation using network partitioning approach
In Networks-On-Chips, (NOC) global interconnection links and routers are the main sources of the power Consumption. In Application Specific NOC (ASNOC) power can be minimized by mapping the Processing Element (PE) on the custom topology rather than mapping on the standard topologies. In ASNOC, the design of the topology plays an important role in minimizing the power consumption. In this paper, we propose a custom topology generation algorithm using network partitioning, to reduce the power of the global interconnection links that connects the router to router. The proposed method is validated through a case study for benchmark video applications MPEG 4 decoder and PIP. The experimental case study shows 26.8% and 37.5% of power saving for the applications MPEG 4 decoder and PIP respectively compared to the existing algorithm. We also achieve 11.76% and 9 % of reduction in average number of hops for MPEG 4 decoder and PIP respectively.

Biological Parameters and Zooplankton Diversity of a Tampara Lake, Chatrapur, Odisha
The biological parameters and zooplankton diversity of a Tampara Lake shows healthy aquatic ecosystem. The plankton constitutes the basic food source of any aquatic ecosystem. Zooplankton diversity is one of the most important ecological parameters in water quality assessment. Zooplankton are strongly affected by environmental condition and quickly respond to any change in water quality. So these are good indicator of ecosystem and occupy an intermediate position between phytoplankton and fish. Hence qualitative and quantitative studies of zooplankton are of great importance. During the study zooplankton diversity in relation to biological parameters was discussed to the investigation find that 22 species of zooplankton belonging to four major groups, i.e. 10 species of Rotifera six species of cladocera and three species of copepoda and three species of protozoan.
