In this paper, in order to show some interesting phenomena of fourth-order hyperchaotic autonomous electric circuit with a smooth cubic nonlinearity, different kinds of attractors, time waveforms and corresponding power spectra of systems are presented, respectively. The perturbation transforms an unpredictable hyperchaotic behavior into a predictable hyperchaotic or periodic motion via stabilization of unstable, aperiodic, or periodic orbits of the strange hyperchaotic attractor. One advantage of the method is its robustness against noise. A theoretical analysis of the circuit equations is presented, along with experimental simulation and numerical results.

Oxidative stress is one of the most popular terms in biomedicine. Oxidative Stress is a general term used to describe the steady state level of oxidative damage in a cell, tissue, or organ, results from an imbalance between radical-generating and radical scavenging systems, i.e. increased free radical production or reduced activity of antioxidant defenses or both. A great number of aromatic, medicinal, spice and other plants contain chemical compounds exhibiting antioxidant properties. In the present study the antioxidant activity and radical scavenging activity of aqueous and alcoholic extracts of Allium sativum Linn. traditionally used by Indian population as folk remedies was evaluated.

Abstract Background: Infantile Digital Fibromatosis is a rare benign fibro proliferative tumour of early childhood. Case characteristics: A six-month-old boy with swelling on the right third digit histopathologically fibromatosis. Observation: Congenital onset in our patient. Message: Reassure about benign nature to avoid unnecessary surgical intervention. Key words: Infantile digital fibromatosis (IDF), benign

The inhibitive action of Tagetes erecta-leaves (TEL) extract on mild steel in 1M HCl has been studied using weight loss, electrochemical polarization and AC impedance measurements and The extract shows a very good inhibition in the hydrochloric acid medium and inhibition efficiency of the extract was found to vary with the extract concentration and immersion time. The maximum inhibition efficiency of 96% was obtained at 0.3%v/v concentration of the extract at 24h immersion time at room temperature. The potentiodynamic polarization data showed that the extract is of mixed type. EIS measurements showed that the dissolution process occurs under activation control. The protective film formed on the surface of mild steel by the adsorption of phytochemical constituents present in the extract was confirmed by SEM studies

Each of us is a unique person, a combination of inherited genetic material and environmental influences. A basic theme and controversial issue throughout the history of psychology has been the debate and investigation of the relative roles of heredity and environment in the formation of individual differences. Despite beliefs that men are born equal, they are not. Every person possesses a unique set of genetic material bestowing them with variations in aptitude, physical development, and capacities, which in turn are acted on by the occurrence of unique environmental experiences some of which even influence the creature prenatally There are many claims, opinions, and arguments about where intelligence comes from - is it from our genetic heritage, or is it a result of the environment and our experiences? A substantial body of research tells us that both heredity and environment affect intelligence.

Road runoff water harvesting is a process in which the water flowing in the road side drains along the hills or plains can be transported and stored in a reservoir and can be used subsequently for agricultural or domestic use. Road runoff harvesting can solve water shortage problems of various hamlets and villages located adjacent to hills and Highways with side drains. This paper focuses on introduction of this system in India and its viability in Indian scenario.

The importance of the relationship between corporate social responsibility and financial performance helps managers to understand the impact of investing in corporate social responsibility, on the cost of financing, as well as on investors in obtaining economic assistive decisions And has provided researchers with more relevant information than other accounting information. The corporate social responsibility of the integrated business processes, by creating innovative methods in them, contributes to improving the organization by improving it, and it affects financial performance, which requires the exploitation of both The benefits, and the benefits of integrating different management systems. The purpose of this research is to investigate the relationship between corporate social authorities and financial performance, and the statistical population of the research is listed companies in Tehran Stock Exchange from 2011 to 2015. The present study is of a kind of applied nature, and in terms of the purpose of correlation, after preparing and extracting the social responsibility data of the company, through a questionnaire and financial performance, through the information in the stock archive, the research variables for Estimation of econometric models is analyzed using EViews software using collected data, which according to the results obtained and the regression models are validated and significant. , And according to the results, there is a significant relationship between social responsibility and financial performance in the companies admitted to the stock exchange. This research will help managers to develop effective corporate social responsibility policies that are needed to achieve their better financial performance in the long run, as well as insights for companies on the role of social responsibility, Providing future benefits.

Shifting to new energy as well as other low carbon solutions was conceived and viewed as serious challenge even to the most developed countries in the world. Hence, with the disadvantaged position of the least developing countries, whom, in most locations around the world are at the highest risk of climate change effect, the challenges will be even more higher. These are from the perspective of technology, finance and policies of ensuring smooth renewable energy transition in these countries. However, within this challenge, there is opportunity to start enjoying new energy particularly in areas where not much investment is done in the fossil technologies. The study highlights these challenges as they are posed by climate change and the opportunities by way of estimating the investment requirements and environmental vis economic benefits of leapfrogging in West African sub-region. Reasons for slow to non-adoption of RE in developing countries as well as arguments for the possibilities of leap-frogging to renewables are also reviewed, so also the challenges/barriers associated with the process of leap-frogging are highlighted. At the end, a simple Emission/Energy Demand Based Strategy depending on energy intensity and necessity is proposed and a very good case-study of leap-frogging to renewables in developing countries is discussed. It is established that, slowly developing countries can and should choose not to be only victims of, but take the opportunity presented by climate change.

Cardiac evidence of Lyme disease are relatively infrequent, occurring within weeks after the infectious tick bite (median of 21 days), and resulting at this stage from a direct borrelial infection of the myocardium, as indicated by reports of spirochete isolation from pericardium and myocardium. Lyme carditis typically presents with a fluctuating degree of atrioventricular block that spontaneously resolves in several days. The management of Lyme carditis does not differ from the treatment of Lyme disease without carditis.
