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.

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.

The Magistrates' Courts Service is a local service. People working here are solicitors or barristers; they may have an arts or social sciences background. Addition to these qualifications their verbal communication is excellent but they have low in analytical and numerical skills. After deeply analyzing the given case about Magistrate Courts Service, certain issues which need to be addressed through effective development program in this study. These issues include lack of skills (mainly analytical and numerical), lack of coordination and consensus in most of the decision and activities performed, low coordination, more than required level of independence. Beside this the information on hand, differs greatly in nature and quality which makes it quite unreliable. Investigation report regarding the Magistrates’ Courts Service has proposed a number of options for change in order to improve the working. These changes are required for the management and administration of courts services in more effective way.

Microencapsulation is a process by which solid, liquid or even gaseous particles are coated with a continuous film of polymeric material, having a diameter in range of 1 to 1000 ?m and are widely used as drug carriers. The purpose of writing this review on microencapsulation by solvent evaporation technique was to compile the recent literature with special focus on solvent evaporation technique for microencapsulation of pharmaceuticals that have recently become leading investigated technologies in the field of drug delivery development. In order to understand the microencapsulation by solvent evaporation technique, the basics was summarized. Afterwards, we have reviewed various solvent evaporation techniques designed and developed until now. Finally, various potential factors influencing microencapsulation by solvent evaporation technique were covered in detail.

In today`s global scenario the demand of Wireless communication service is growing rapidly. In order to serve a high user population in a limited spectrum, using dense grids of microcells and picocells is one of possible schemes. While small cells relieve the capacity problem, frequent movements of mobile users across cell boundaries pose a big network control challenge: handover In personal communication networks (PCN) supporting network-wide handovers, new and handoff requests compete for connection resources in both mobile and backbone networks. Due to limited range of transceivers, mobile users can communicate only with base station that reside within the same microcell at any instant of time. The number of handovers during a call will increase, as the cell radii decreases, thus affecting Quality of Service (QoS). As the handoff rate increases, bandwidth management and traffic control strategy (call admission control, handover procedures etc) become more challenging problems in wireless ATM networks. Thus in a wireless environment, we need to consider two additional QoS parameters; dropping probability of handoff calls and blocking probability of new calls. Handoff calls require a higher congestion related performance i.e., blocking probability relative to new calls because forced call terminations due to handoff call blocking are generally more objectionable than new call blocking. In general, most of the previously proposed schemes for radio channel allocation in cellular networks reduce handoff call blocking probability substantially at the expense of increasing the new call blocking probability by giving higher priority to handoff calls over new calls in admission control. This reduces the total admitted traffic and results in inefficient utilization of wireless channels. The tradeoff between the new and handoff calls blocking probabilities should be defined. In this paper, a modified Hybrid scheme has been proposed for handover in ATM-based PCN, which combines reservation and queuing schemes for handoff calls. Also , the scheme assigns the handoff reserved channels to new calls depending on the locality principle in which the base station with the help of location estimation algorithm in the mobile location centre predicts the position of the mobile terminal. Here the FIFO and Measurement Based Priority Scheme (MBPS)queuing scheme are used. Thus the modified Hybrid Scheme is designed to have a remarkable reduction in forced termination Probability (FTP) along with to improve channel utilization while satisfying the QoS of the calls.
