Role of fine needle aspiration cytology in bone lesions

Background: FNAC is considered an important procedure in the diagnosis of bone tumors because of its high accuracy. In our study FNA was performed in patients to study the role of FNAC in the diagnosis of bone tumors and to evaluate its usefulness as a diagnostic modality . Methods: Fine needle aspiration was performed on 54 patients whose age ranged between 5 – 75 years with a male to female ratio 1.84 :1 presented with various bone lesions. The bone lesions included 42 (78%) primary lesions, 5 (9.3%) metastatic deposits and 7 (12. 7%) malignancy of related structures involving the bone. Results: 47 biopsy specimens were available for cytohistological correlation and cytological findings of 45 cases correlated with histopathology. The overall diagnostic accuracy was 95.92%, with 100% sensitivity and specificity. The predictive values of positive as well as negative test were 100% . Conclusions: Thus FNA was found to be a safe and an extremely useful, rapid method in the preliminary diagnosis of bone lesions .
Central Bank Independence, Centralized Wage Bargaining and Price Stability in a Monetary Policy Game

This paper addresses the usefulness of studying the interplay between central bank independence and centralized wage bargaining in the context of a repeated monetary policy game. Conventional macroeconomic wisdom suggests that because of increased credibility and the possibility to overcome inflationary bias, increased central bank independence has a negative effect on inflation rates. However, the benefits of increased central bank independence have lately been called into question. This paper seeks to answer whether the degree of CWB may affect the equilibrium in the monetary policy game and thereby also shed some light on the effect of CBI. The theoretical analysis considers two potential effects of CWB in the monetary policy game. The first stems from union inflation-aversion and the other from the effect of non-unionized wage bargainers. These effects are found opposing, which means that there is a possibility for a hump-shaped relationship between CWB and inflation. A small empirical study of 19 countries over three time-periods is also conducted. CBI turns out to have a negative effect on inflation. The hypothesis of a hump-shaped relationship between CWB and inflation also gains some support.
Can aerosol decrease cloud lifetime?

Cloud responses to changes in aerosol remain a dominant uncertainty in the radiative forcing of climate. Two main constructs related to aerosol effects on clouds have been postulated: (i) the “albedo effect” whereby anthropogenic aerosol results in increased droplet concentrations that generate increases in cloud albedo, all else (particularly cloud water) being equal; (ii) the “lifetime effect” whereby anthropogenic aerosol suppresses precipitation and results in clouds with more liquid water, higher fractional cloudiness, and longer lifetimes. Based on new observations presented here, and supported by previous fine‐scale modeling studies, we suggest that the balance of evidence shows that non‐precipitating cumulus clouds can experience an evaporation‐entrainment feedback, and respond to aerosol perturbations in a manner inconsistent with the traditional “lifetime effect. ” Because most cumulus clouds evaporate without producing significant precipitation, this is particularly relevant to estimates of aerosol indirect effects on climate.
Effect of 1B/1R Translocation on Selected Grain Quality Parameters in a Set of Doubled Haploid Wheat Lines

A set of quality parameters (crude protein content, Zeleny sedimentation test, wet gluten content, gluten index, albumins + globulins content, gliadin content, sum of glutenins, proportion of albumins + globulins in crude protein and relative viscosity) was tested in 17 doubled haploid (DH) wheat lines differing in the presence or absence of 1B/1R translocation. The presence of 1B/1R translocation (allele Gli 1B3) affected the significantly higher content of albumins and globulins and significantly lower value of gluten index. Nevertheless, a certain translocation influence on the other parameters (Zeleny sedimentation test; relative viscosity; proportion of albumins + globulins in crude protein) was also registered. The deteriorative effect of the 1B/1R translocation on indirect technological grain parameters was confirmed more markedly in gluten index than in Zeleny sedimentation test. A high number of significant differences between lines was found in Zeleny sedimentation test, content of glutenin, content of albumins + globulins and their proportion in crude protein. In spite of lower variability between lines relative viscosity showed a high dependence on genotype and was indifferent to the other quality parameters.
Gender Moderates the Relationship Between Empathy and Aggressiveness in Sport: The Mediating Role of Anger

This research investigated whether gender moderates, and anger mediates, the relationship between empathy (i.e., perspective taking and empathic concern) and aggressiveness in sport. In Study 1, perspective taking and empathic concern were negatively associated with aggressiveness, and this effect was stronger in women compared to men. In Study 2, perspective taking was a negative predictor of aggressiveness and antisocial behavior in sport, and anger mediated these relationships in women but not in men. Our findings suggest that empathy and emotion-based strategies targeted at reducing aggressiveness in sport need to be tailored for male and female athletes.
PLACIS: a general project-based learning framework illustrated with a concrete example

PLACIS (Collaborative Platform for Systems Engineering) is a project funded by the French National Agency for Research under “Investments for the future” program. PLACIS started in September 2012 22 eme Congres Francais de Mecanique Lyon, 24 au 28 Aout 2015 and is run by Institut Polytechnique Grand Paris (IPGP, gathering ISMEP – Supmeca, ENSEA and EISTI). This large-scale project promotes active learning and teaching through industrial, international and at-a-distance collaborative projects, carried out by engineer students. Since its beginning, PLACIS has gained in maturity not only with new students’ projects and new partners, but also with the development of new tools like a future learning platform: an adaptive, collaborative, semantic and social web 3.0 distributed learning environment, and an implementation of a toolbox for teachers to assess skills and knowledge in project-based learning with an Erasmus+ project in parallel (EPICES: European Platform for Innovation and Collaboration between Engineer Students). The objective is to develop or create the involvement of teachers and students into new teaching practices (project-based learning, problem-based learning, small private online courses) necessary for the implementation of an alternative to the traditional configuration courses / supervised work / practical classes. All these aspects enable us to see the first achievements of what is the main goal of the project: to train students not only to become classic engineers, but also to be able to understand multidisciplinary and industrial issues, to work in teams, with people from different cultures and, more generally, to be actors of their curricula and to move easily in today’s and tomorrow’s industrial world. We can easily rely on the example of an industrial project especially set up from the beginning of PLACIS in September 2012 and which is still in progress between Istituto Motori – CNR (IM-CNR), Universita di Napoli Federico II (UNINA) and Institut Polytechnique Grand Paris (IPGP).
Histological evaluation of the effect of topical application of Curcumin powder and essential oil on skin wound healing

Background: Herbal medicine can be called one of the branches of medicine in various forms. Turmericcurcumin has proved its efficiencies a coloring, flavoring agent and has been traditionally used in medicine, exhibiting remarkable anti-inflammatory and antioxidant properties. The varied biological properties of curcumin and lack of toxicity even when administered at higher doses makes it attractive to explore its use in various disorders like diseases of skin. It is good potential agent for wound healing. Materials and methods: Sixty four new Zealand rabbits were used in this study ,they were divided into four groups,each group was subdivided as follows:Experimental groups(8 rabbits) right facial side of animals for essential oil application and left facial side animals for curcumin powder application,8animals as control group(right facial sides) . Histological assessment regarding the count of inflammatory cells was performedon all studied samples for the healing intervals (3, 7, 10, and14 days). Results: Histological findings of the study showed that re-epithelialization, wound contraction were accelerated after topical application of curcumin material especially the essential oil at wound site. Conclusion: Topical application of curcumin essential oil was significantly effective in skin wound healing as compared to curcumin powder.
Modelling Pulse Magnetic Welding Processes – An Empirical Approach

In recent years pulse magnetic welding technology gained an ever increasing attention. The process was known for over 40 years, yet the poor knowledge of process parameters as well as the difficulties concerning the calculability of the process due to lack of adequate software, performance and appropriate material models hindered the application of the technology. In the past, some simulations treating the process of explosive welding were conducted. There, the assumption was made to define a friction condition to the boundary regions which was reasonable due to similar conditions in the collision region during the process. However, at pulse magnetic welding processes, the contact forces are highly transient and have big gradients over the geometry. In this paper a new empirical approach is presented, which gives the possibility of modelling the welding process by parameter-controlled bonding at the welding interface. The pulse magnetic forming process was simulated by loose coupling of electromagnetic and mechanical FEM software with the commercial code ANSYS. As geometry the joining of a duct with an internally positioned conical bolt was chosen. The material used for both duct and bolt was EN AW 6063. First of all the influences of heat generation were analyzed. Therefore, the additional thermal simulation was coupled with the electromagnetic and the mechanical simulation. The heat generation caused by the plastic deformation was considered. As the resulting temperatures were below the melting temperature of the material, further simulations were carried out without thermal simulation. In order to calibrate the welding model, a set of relevant parameters were defined. It included the cumulative plastic work, the plastic deformation in collision direction, the normal and the tangential components of the collision velocity and the collision angle between the two parts. By comparing the simulation with experiments carried out at the same specific process parameters, it was possible to reduce the set of parameters to the normal collision velocity and plastic deformation. Based on their distribution, the parameter control of the bonding condition could be adjusted. Further experiments gave a high accordance to the simulations carried out with the parameters found for this model.
Beleaguered Chimpanzees in the Agricultural District of Hoima, Western Uganda

Abstract: With approximately 5,000 chimpanzees, Uganda is important for the conservation of the eastern subspecies Pan troglodytes schweinfurthii. The population distribution is highly fragmented, however, and the prospects for the long-term viability of many populations will be greatly improved if dispersal opportunities are maintained between major forests via migratory corridors. Chimpanzees in unprotected human-dominated habitat outside the main forest blocks are often ignored by research and conservation efforts. This study assessed the status and distribution of chimpanzees in northern Hoima District, western Uganda. The survey region covered 400 km2 between 1°26′–1°37′N and 31°09′–31°32′E, and separates two major forest blocks, Bugoma and Budongo. Chimpanzees use small forest fragments along watercourses throughout this region, both on private or communal land and in small government reserves, and a number of distinct groups (‘communities’) are present. There has been no evidence to indicate that chimpanzee populations are isolated; on the contrary chimpanzees appear highly mobile in this forest-farm habitat, confirming the region's corridor potential. At one site in the region, chimpanzees occur at an estimated density of 0.66 individuals/km2 which, if extrapolated across the survey area, implies a larger population than previously thought. Recent and rapid habitat change resulting from unregulated timber extraction and clearance of fragments for agriculture—particularly for cash crops such as tobacco—has exposed the chimpanzees, causing increased negative interactions between apes and farming communities. The chimpanzees in northern Hoima are unlikely to survive without immediate intervention.
Multi-Tasking Vs. Screening: A Model of Academic Tenure

The paper develops a model of academic tenure based on multi-tasking and screening. A professor has two tasks, researching and teaching. We assume that researching performance is easy to measure but teaching performance is immeasurable. Then Holmtrom and Milgrom's (1991) classical muli-task principal-agent model implies that the only way for the the university to "incentivize" teaching activity is decreasing the incentive power to researching activity. This justifies the low-powered contract to tenured professors. However, with low-powered contract, the university will face serious informational problem in the process of enrollment, either transferring rents to the candidates with low ability if the wage level is high, or suffering from the potential occupational vacancy if the wage level is low. To this dilemma, the up-or-out contract is a possible solution.
Azospirillum brasilense mutant affected in motility, nitrogen fixation, flocculation and exopolysaccharide (EPS) production

Members of genus Azospirillum are capable of nitrogen fixation under microaerophilic conditions in association with the roots of several grasses, capsular and exocellular polysaccharides (PS), are responsible for the binding of Congo red dye to Azospirillum cells, the PS are also involved in formation of cellular aggregates. Tn5gusA was used to generate an Azospirillum brasilense UAP 154/6-51 mutant, was analyzed in activity of β-glucuronidase. The cell surface of the mutant was unable to bind Congo red dye (white), and was unable to cell aggregation (flocculation), it is not capable nitrogen fixing and does not demonstrate any motility. The present paper describe these phenotype differences and demonstrates that a single mutational event is involved, that is it a pleiotrophic mutant.
JOHN CALVIN'S PERSPECTIVE ON MUSIC AND WORSHIP, AND ITS IMPLICATIONS FOR THE SEVENTH-DAY ADVENTIST CHURCH

Different views on worship and music have been expressed by different Reformers. The Reformers rejected some aspects of medieval worship such as the Gregorian chant, the use of elaborate vocal and instrumental music, overly theatrical performances at worship, the unwarranted expense of elaborate ceremonies, enormous pipe organs and the uselessness of text unintelligible to the common man. The Reformers aimed at introducing simple forms of worship and music in the Church, and to restore the true worship of God and therefore introduce congregational singing and participation in worship. This paper surveys John Calvin’s views on worship and Music. Calvin held that the Word of God should be central to worship and that prominence should be given to the Bible over any other obsessions. He therefore prohibited many things in worship because he wanted God to be the focus of worship and devotion. The study concludes that although the Church today cannot limit itself to singing of the Psalms alone, nonetheless, music sung in the Church should be Bible-based to draw the attention of worshippers to God.
Technology acceptance model of online learning management systems in higher education: A meta-analytic structural equation model

The present meta-analysis employs meta-analytic structural equation modeling (MASEM) to quantitatively synthesize studies that investigates college students’ acceptance of online learning managements systems. This study combined meta-analysis and path analysis to extend and refine the Technology Acceptance Model (TAM) within a higher education online learning environment context. Analyses of 13 studies representing 3407 undergraduate students from worldwide universities were conducted. The study investigated four path models (e.g., fixed-effects and random-effects) measuring different combinations of variables and formed conclusions about the relationships between the variables that were available. The model fit of each path model suggested mixed-results. Some models resulted in an acceptable fit, while others resulted in poor fit. Invariance tests resulted in statistically different findings across multiple parameter estimates, suggesting little to no replicability of findings across studies. Educational technology researchers should be cautious when forming conclusions about undergraduate online learning management systems based on the TAM.
Analysing, pursuing and networking: Towards a validated three-factor framework for entrepreneurial competence from a small firm perspective

Moving beyond general personal traits as predictors for success, a growing volume of research acknowledges that entrepreneurial core processes are enabled by specific competencies which can be learned, further refined and developed. The research objective of this article is to develop a framework for entrepreneurial competence in a well-defined small firm sector by elaborating and empirically validating an existing categorization of entrepreneurial competence. The dataset includes 348 small firm owner-managers who participated in an educational programme, established to pursue new business opportunities in the Dutch agri-food sector. Exploratory factor analysis and confirmatory factor analysis revealed that three domains constitute the heart of entrepreneurial competence in this small firm context: ‘analysing’, ‘pursuing’ and ‘networking’. These three competence domains provide professionals active in sector development, small business support and (vocational) education with an empirically valid framework of clearly discernible elements of entrepreneurial competence. This framework also encompasses insights on education and learning.
THE PERCEIVED IMPACT OF HUMILITY ON TEAM EFFECTIVENESS: AN EMPIRICAL STUDY

We assess the perceived impact of leaders humility (both self and other-reported) on team effectiveness, and how this relationship is mediated by balanced processing of information. Ninetysix leaders (plus 307 subordinates, 96 supervisors, and 656 peers of those leaders) participate in the study. The findings suggest that humility in leaders (as reported by others/peers) is indirectly (i.e., through balanced processing) related to leaders’ perceived impact on team effectiveness. The study also corroborates literature pointing out the benefits of using other-reports (rather than self-reports) to measure humility, and suggests including humility into the authentic leadership research agenda.
Meteorological and land use controls on past and present hydro‐geomorphic processes in the pre‐alpine environment: an integrated lake–catchment study at the Petit Lac d'Annecy, France

A wide range of environmental records is integrated in order to reconstruct the mechanisms of flooding and sediment transport within the 170 km2 Petit Lac catchment, Annecy, France, over time scales of 10−1 to 102 years. These records include sequential lake sediment trap samples and cores, floodplain stratigraphies, dated landform assemblages, hydro‐meteorological records, and documented histories of river channel and land‐use change. Mineral magnetic measurements are used as the basis for classifying catchment sediment sources and tracing sediment movements through time. Records of magnetic susceptibility for monthly sediment trap samples (1998–99) track seasonal discharge, peaking in winter and spring. Magnetic records in lake sediment cores are compared against and tuned to precipitation records to provide dated proxy records for past discharge spanning sub‐annual to decadal time scales back to 1826. Calculated sediment accumulation rates in lake sediment cores are used as proxies for time‐averaged catchment sediment load. Analysis of the results reveals that climate and land‐use controls on the hydrological and sediment system are complex and vary according to the time scale of observation. In general, cycles of agricultural expansion and deforestation appear to have been the major cause of shifts in the sediment system through the late Holocene. Deforestation in the 18th century may have caused a number of high‐magnitude flood and erosion events. As the time scale of observation becomes shorter, changes in climate and hydro‐meteorological conditions become progressively more important. Since the mid‐19th century, smoothed records of discharge roughly follow annual precipitation; this is in contrast to sediment load, which follows the trend of declining land‐use pressures. Episodic erosion events during this recent period seem to be linked to geomorphic evidence for slope instability in the montane and sub‐alpine zones, triggered by intense summer rainfall. At the annual scale, changes in seasonal rainfall become paramount in determining sediment movement to downstream locations. The study demonstrates that the connections between forcings and responses span a four‐dimensional array of temporal and spatial scales, with strong evidence for dominantly nonlinear forcing–response mechanisms.

Optimisation study of gum extraction from Basil seeds (Ocimum basilicum L.)

Summary Basil seed (Ocimum basilicum L.) is cultivated in large quantities in different regions of Iran. This seed has reasonable amounts of gum with good functional properties which is comparable with commercial food hydrocolloids. A central composite rotatable design was applied to evaluate the effects of temperature, pH and water/seed ratio on the yield, apparent viscosity and protein content of water-extracted Basil seed gum. All of the variables significantly (P 0.05). Numerical optimisation determined the optimum extraction conditions based on the highest yield and viscosity and the lowest protein content as being temperature 68.71 °C, pH 8.09 and water/seed ratio 65.98:1. Power law model well described non-Newtonian pseudoplastic behaviour of BSG. Flow behaviour index (n) and consistency index (K) of 1% crude and pure BSG samples were 0.306, 0.283 and 17.46, 20.22 Pa sn, respectively.
