This study presents the first record of Halodule pinifolia on the eastern coast of Sri Lanka, approximately 310 km along the coastline from the previously recorded location (Kapparathota, Weligama). Further, this study describes the new locality of the nationally endangered seagrassspecies Halophila beccarii to Valaichchenai Lagoon, 26.5 km north of Batticaloa Lagoon, where itwas previously recorded, along with the presence of two other species, Halophila ovalis and Haloduleuninervis. While the species composition the seagrass habitat of Valaichchenai Lagoon might changein the near future due to the impact of climate change, multiple threats already exist at these newlydiscovered seagrass habitats, including multiday fishing vessel movements, the collection of shellson the seagrass beds, and solid waste dumping into the lagoon. Decline of seagrass abundance inValaichchenai Lagoon would negatively impact the food security and income generation of fishers.Therefore, a well-established legislative framework and systematic long-term monitoring of seagrassin Valaichchenai Lagoon are essential in order to develop seagrass conservation plans beforepopulations decline significantly or become locally extinct.

In this paper, the application of passive vibrational linear absorber on the indirect reduction of blade vibrations using its mounted on the disk-blade system is studied. The absorber receives the vibration energy of blade through a structural coupling of the disk with blade and losses it by its linear damping. Due to cyclic symmetry, the analysis of the bladed disk is reduced to the number of DOFs in a single sector. A cyclic transformation from physical to modal coordinates is used to perform this reduction. Natural frequencies and forced responses of the system are obtained by solving the characteristic and algebraic equations, respectively. The case study of a steam turbine includes 259 blades in 37 packets of 7 connected blades attached to the perimeter of the disk. Cyclic symmetric finite element analysis at 3000rpm is used to extract the natural modes and frequency diagram of the system. A two DOFs reduced-order model is iDentified for modeling the frequency-veering region. This region has been formed between the first and second families of natural modes and there is a strong coupling between them in this region. In addition, this region is close to the system excitation line and the possibility of resonance exists. Therefore, some linear energy absorbers are mounted on the disk for the indirect vibration reduction of blades. The initial optimal parameters were determined for the first and second modes using Den Hartog relations. These parameters reduced the system vibrations and they were used in subsequent optimization. The optimization has resulted in the improvement of absorber performance exclusively around the second mode, in compare with the tuned system by Den Hartog relations.

The stability and galloping characteristics of iced quad bundle conductor are studied in this paper. Firstly, the aerodynamic coefficients of iced quad bundle conductor and single conductor under four different working conditions are obtained by wind tunnel test. Secondly, the equivalent aerodynamic coefficients at the central axis of the quad bundle conductor are obtained, and the equivalent aerodynamic coefficients are compared with the aerodynamic coefficients of each sub-conductor of the quad bundle conductor. Then, based on the Den Hartog instability mechanism and Nigol instability mechanism, the stable and unstable range of the equivalent coefficients of the quad bundle conductor are analyzed. Finally, the galloping characteristics of the quad bundle conductor are studied by combining with the equivalent aerodynamic coefficients at the central axis of quad bundle conductor. The results of the wind tunnel test show that the aerodynamic coefficients increase with the decreasing of the wind speed. The stability analyses show that the higher the wind speed is, the smaller the Den Hartog coefficient is the easier the Den Hartog’ galloping would occur. Furthermore, the higher the wind speed is, the smaller the Nigol coefficient is, the easier the Nigol’ galloping would occur. The analysis of galloping characteristics shows that when the conductor is located at stable state, the displacement in the y-axis direction would be much greater than the displacement in the z-axis direction.

The celebrated German sociologist, Norbert Elias, in his magnum opus, Uber Den Prozess der Zivilisation, through a long-term social-historical analysis, recasts the processual configurations of manners since Renaissance, searching how the Europeans came to be known 'civilized. ' A group of renowned scholars of Elias, then his editors of the English translation, edited the Edmund Jephcott’ s fine translation in 1999, The Civilizing Process, and put the long introduction written by Elias thirty years after the first publication, in 1968, at the end of the edited version, as a Postscript. The Persian translation of The Civilizing Process appeared in 2018 by Qolam Reza Khadivi. We seek to do a contrastive analysis based on the Persian translation of the English version, whilst Khadivi claims he has translated from the original German text. The available Persian translation is incomplete since the preface, first volume, postscript, appendix, and most of the author’ s notes have not been translated yet. As our scrutiny shows, the Persian translation of The Civilizing Process has so many formal problems, it lacks consistency and does not pursue a good norm of wordage, in addition to numerous written and editorial mistakes.

After the victory of glorious Islamic revolution that ended autarchy in Iran, the seizure of U.S espionage Den in Tehran led to abolishment of colonial domination over the country's affairs. The importance and various domestic and foreign reflections of this inciDent forced political activists, parties and different groups across the country to take clear stances. The main question to be answered in this paper is that the impact and consequences of this event on Iranian domestic political events.In this regard different viewpoints of political parties and groups evaluated. The result showed that the seizure of U.S espionage Den in Tehran cause to disclosure the real positions and attitudes of individuals and major groups linked to the Islamic Republic of Iran and also led to the refinement of domestic political system.The logical outcome of this process includes: elimination of rightist and leftist non-Islamic, eclectic thoughts, gradual control of politically sensitive posts by genuine revolutionary youths, increase of their self-esteem and self confiDence and ultimately strengthen national integration and unity of the Iranian society. In fact, by seizure of U.S espionage Den in Tehran, the revolutionary forces who followed the path of Imam, corrected the route of Islamic Republic and prevented its deviation.

Purpose: The aim of this study was to explain a model for employees' proactive behaviors in which the role of self-construal, job indepenDence, commitment and proactive personality were considered. Method: By method, this research is a descriptive correlational survey, and by purpose, is an applied research. The statistical population of this study included the staff of Day Insurance Company, a random sample of whom participated in this study and responded to questionnaires of job depenDence (Bishop & Scott, 2000), job indepenDence (Morgeson & Humphrey, 2006), proactive personality (Batemann & Crant, 1993), self-construal (Lu & Gilmour, 2007), commitment (Ellemers, de Gilder & van Den Heuvel, 1998), career-oriented proactive behavior (Belschak & Den Hartog, 2010), and work unit-oriented proactive behavior (Griffin, Neal & Parker, 2007). Data were analyzed using structural equation modeling. Findings: Findings showed that indepenDent self-construal and depenDent self- construal through career commitment and commitment to work unit affect career-oriented proactive behaviors and work unit-focused proactive behaviors. Also, the moderating role of job indepenDence and job depenDence and proactive personality in the occurrence of proactive behaviors was not confirmed. Conclusion: According to research findings, paying attention to the types of self-construal and types of commitment of employees to the career and work unit can provide the ground for the occurrence of proactive behaviors in employees.
