The study was carried out to investigate the influence of leadership styles and perceived organisational politics on work engagement. The sample for the study consisted of 120 participants with a mean age of 36.59 years. Fifty-Eight (58) of the research participants were males while 62 were females. Participants were randomly selected from the population of civil servants at the Governor’s office in Ado Ekiti, Nigeria; using the multi-level random sampling technique. Six hypotheses were tested. Results revealed that perceived organizational politics has no significant influence on work engagement. However, perceived organizational politics influenced the dedication and vigour dimensions of work engagement. Both autocratic and democratic styles of leadership independently and jointly influenced work engagement; and there was no significant interaction effect of leadership styles and perceived organizational politics on work engagement. There was no significant main and interaction effect of sex, rank, and age of employees on work engagement. There was a significant effect of sex of leaders on the use of autocratic style of leadership while sex of leaders did not influence democratic style and perceived organizational politics. Results of present study also revealed that there was a positive relationship between leadership styles and work engagement together with its subscales. Finally, there was a significant relationship between perceived organizational politics and autocratic leadership style but not on democratic style. Findings were discussed in line with previous research findings and it was recommended that organisations should not encourage or foster political behaviours that may hamper work engagement of employees; such as preferentially treating the employees. It was also recommended that the contingency approach to leadership should be encouraged in organizations, where the situation at hand will determine the type of leadership style to use and not just get fixed to a particular leadership style.

The tribal who were protecting the natural resources for the centuries are now being deprived of these natural resources for the development projects. The tribal area is full of natural resources which contains bauxite, iron ore, coal etc. these are required for the manufacturing industries. Deprivation of these natural resources are making them more vulnerable marginalized group. They become not only socially and economically marginalized groups but also physiological and cultural marginalized groups. The State is required to take ‘affirmative action’ to stop the marginalization of the tribal group. Generally the ‘affirmative action’ means as reservation policies for the marginalized groups in jobs. It is not the whole truth meaning of ‘affirmative action’. Any action of the State to minimize the difference between the advanced group of society and non-advanced group of the society is affirmative action. The Central Government has enacted a law titled as The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 to reduce the pain caused to tribes by development induced displacement. This article will explore how The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006 is working as affirmative action for tribes. It will also enumerate the pain suffered by the tribes in the process of development projects.

Categories of intellectual capital is important that over last few decades that has attracted attention of academic circles. actually change the pattern of corporate and with the emergence of new challenges and compete in the global arena, companies to maintain their competitive advantage should be worth more to think as intellectual capital as a key factor companies to create value and sustain competitive advantage has become known then identification and reporting of intellectual capital issue importance for corporate managers and users of financial statements. In this study, the relationship between intellectual capital components and financial performance of listed companies in the cement industry Studied at the Tehran Stock Exchange. The study period is 2007 to 2011 years. For test the hypotheses and data analysis from method of least squares regression and neural networks are used. The results indicated a significant relationship between intellectual capital and corporate financial performance indicators. On the other research findings can be concluded between intellectual capital and financial performance of companies in the same (similar) craft approach to regression analysis and neural networks value added intellectual coefficient model Polic (VAIC) gives similar results however, the performance impact on capital employed human capital is a significant difference in performance.

The objective of our study was to search for the ultrasonographic afflictions of the metacarpophalangeal and metatarsophalangeal joints notably ultrasonographic synovitis , intra articular liquid accumulations , cartilaginous vascularisation as well as bone erosion and to compare them with the clinical aspects ( pain , swelling , limitations of mobility ) . MATERIALS AND METHODS : It was a transverse study ,comprising exclusively the cases of JIA corresponding to the criteria of ILAR 2001 . All the patients were clinically examined to look for pain , synovitis or articular limitations. Linear sound echography ( 14 MHz ) with doppler power , was used . The OMERACT criteria were utilised for evaluating the ultrasonograhic synovitis ; The software SPSS21 was employed as test statistic. RESULTS : 34 patients were included , with 612 joints . The mean age was 10,80 ± 3,29 . Total number of painful articulations of 31 ( 94% ) ; synovitic articulations was 4 ( 12 % ) ; total number of ultrasonography synovitis was 110 ( 18 %). In patients with normal clinical examination, ultrasound showed abnormalities in 159 (27 %) joints , the most frequent localization was at the MTP joints in 86 ( 54% ) p < 0,001.Presence subclinical synovitis for 73 ( 66 %) p< 0,001 . CONCLUSION : Our study detected subclinical synovitis ;this study suggests that ultrasound is an important supplement to clinical examination and should be performed in a systematic way to evaluate the activity of the disease. 

Zinc oxide nanoparticles doped with Vanadium of varying concentrations were synthesised by Sol-gel method. Samples prepared after annealing for 2 hrs at 600 oC are characterised by XRD,UV-Vis Spectroscopy, SEM and EDS. The hexagonal wurtzite structure is maintained in ZnO after vanadium doping at high concentration (15 at.%) as confirmed by X-ray analysis. The absorption edge of ZnO is red shifted by increasing the vanadium concentration. SEM shows the nanoparticle nature of the ZnO particle, molar concentration of dopants is confirmed by EDS analysis. The photo catalytic activity of Rhodamine-B dye solution under visible light is better for V-doped ZnO as compared to pure ZnO.

Steganography is a captivating area of research in the new modern world. Steganography is a form of covert communication in which a secret message is invisible within a carrier message. Various image Steganography techniques have been proposed. The user data should be made secret in order to have the user’s privacy and security. This novel algorithm represents the encryption and decryption of medical data of the patient and the patient’s medical image using LSB and chaotic systems. In this paper, investigate diverse Steganography techniques and tools. The chaotic signal generation and the result analysis are done by using the Matlab 7.10.

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.

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.

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.
