The main aim of our project is to avoid conflicts at intersections and cross sections by proposing a Safe and efficient design of Four Phase Traffic Signal. At intersections where there are large number of crossings and right turns, there will be a possibility of several accidents or traffic jams due to the in order movement of traffic especially at cross sections. The earlier practice of controlling the traffic by a traffic police using stop signs alternately at the cross roads so that one stream of traffic is allowed while the traffic flow from the other stream is stopped was quite effective. But now a days, due to the increase of traffic as well as pollution, a lot of difficulties are being faced with the employment of a traffic police. In this aspect, the same problem is been faced at Sreenivas Centre in Nandyal which is a four legged intersection. The heavy traffic flowing from bus-stand towards Atmakur and Srisailam causes a lot of conflicts in the traffic flow from Nunepally towards Gandhi Chowk and Byrmal Street . So in this connection, in order to have a pleasant and safe travel, there should be an orderly movement of traffic which is possible through signal control. So there is a strong requirement of signal regulated traffic flow for the four legged intersection at Sreenivas Centre. This project deals with the design of cycle length for the four phases by Webster method.

In our country most of the population has agriculture as a primary source of income. Agricultural output consist of 16% of India GDP but in most parts of our country there is scarcity of water. To give boost to agriculture the earliest leaders of the country had given primary importance to irrigation projects. But day by day it’s becoming need of the hour to utilize micro irrigation techniques like drip and sprinkler irrigation. In our country most of the farmers utilize conventional process of pipe collection. But it effects the life of pipes, while collecting the pipes it forms scratches, minute holes, bends and while utilizing next time its efficiency has been decreased so these paper deals with the application of a simple mechanism to coil the pipes and collect it without bending or forming twist and increasing its efficiency and long life. It deals with very basic but un-noticed problem related to drip irrigation pipes.

The Efficiency, Performance and Activity of a RDBMS must be consistent. This consistency is achieved through Concurrency Control. Concurrency control deals with the issues involved with allowing multiple people simultaneous access to shared entities, be they objects, data records, or some other representation. The Concurrency Control mechanism ensures that the database maintains its consistency. Concurrency control of distributed transactions requires a distributed synchronization algorithm, which has to ensure that concurrent transactions are not only serializable at each site where they execute, but that they are also globally serializable. The advanced protocols put forward are focused on increasing the level of concurrency and simultaneously decreasing the rate of transaction restarts. Some protocols also compromise consistency in order to achieve concurrency. Several Concurrency Control algorithms have been suggested and implemented and used in a variety of real world applications. This article reveals the analysis of various Concurrency Control Techniques on the database systems and further discusses some of the Hybrid Techniques, which provide efficient Concurrency Control on database systems.

Today’s enterprise networks are distributed to different geographical locations and applications are more centrally located, information represents the most important asset. With the growing number of data communication services, channels and available software applications, data are processed in large quantities and in a more efficient manner. This technological enhancement offers new flexible opportunities also measure security threats poses in the networks. These threats can external or Internal, external threats divided as hacking, virus attack, Trojans, worms etc. There are thousand and thousand of different viruses these days which improve every day. Although the wild spread of new and strong viruses, it still infects and spread only with user’s permission. This research paper highlights the phases of computer virus, computer virus, history of worst computer attack, type of computer virus with effect on computer & few examples of virus on their types, working of computer virus, and problem occur due to virus in computers.

Various companies have and are planning to market their products into the rural areas. This paper basically talks about all those problems that the Co(s) may or have faced in promoting their products in the rural markets. Different challenges exist for the managers in how to best market their brands and establish themselves amongst rural people. In addition to the challenges & hindrances, the report also focuses on many opportunities that basically attract the marketers to come and promote their products. A vast potential exists in the rural areas that has been left unexercised for a long time. Now due to the saturation point that has or is about to be reached in the Urban & Semi-urban markets, the Co(s) are focussing now onto the rural areas and trying to capitalise on the great potential that the rural areas have in store. Thus the research paper covers all these aspects quite extensively to present the deep insights that prevail in the rural market scenario.

This study provides a small scale survey of English verbs that can take cognate objects (CO) both in Pakistani and British fictions in English language. Frequencies of the verbs along with cognate object constructions occurring in Pakistani English fiction (PEF) and British English fiction (BEF) have been compared and analyzed using AntConc 3.2.2w (windows) 2008. Several syntactic properties of cognate objects have also been investigated: such as the ability to take modifier, possibility of the cognate objects to be used as pronouns (it – pronominalization) have also been verified in cognate object constructions (COC) in Pakistani as well as in British English varieties. Focus of the study is on the characteristics of English verbs. It has been found that cognate object constructions are used less in PEF as compared to their presence in BEF. Proving the fact that cognate object constructions as the complex sentence structure. As English is not the native language of Pakistan, so the writers usually avoid the usage of cognate object constructions in PEF. The study establishes Pakistani English as an independent variety using its own distinctive linguistic features.

This quantitative descriptive study aimed to identify the influence of coaching relationship on the coaching communication by the perception of polytechnic lecturers. A total of 411 lecturers randomly selected from the five polytechnics which successfully obtained an overall excellent performance including academic standards and quality management through the recognition of the polytechnic ratings. Data for this survey were collected through a questionnaire which was adapted from an instrument used by Heslin, VandeWalle, and Latham (2006), and Gregory and Levy (2010). The results of multiple regression analysis showed that coaching relationship had positive and significant influence on coaching communication. In term of the implications, this study showed the role of the middle manager is extremely important in creating the coaching relationship in order to improve coaching communication performance.

A diabetic foot ulcer is one of the leading causes of the hospitalization among diabetic patients. This study was conducted to know the clinical and sensitivity profile of diabetic foot ulcer patients. Total 134 pus samples were collected from patients having diabetic foot ulcer. Samples were processed as per standard guidelines. All the pus samples yielded growth of organisms making total of 148 isolates. Out of 148 bacterial isolates, 85 were gram negative bacilli and 58 were gram positive cocci. In gram positive organism Staphylococcus aureus (17%) was the predominant isolate followed by CONS (12%), while Escherichia coli (20%) was the predominant isolate followed by Pseudomonas spp., (18%) in gram negative organism. The Gram negative bacteria showed good activity against amikacin, cefotaxime, ceftazidime, ceftriaxone, gentamicin and imipenem. E. coli, Klebsiella spp., and Proteus spp., showed 55.5% to 100% resistance to amoxyclav and ampicillin. Pseudomonas spp., showed 100% resistance to ampicillin and 96.2% to amoxyclav. All the Gram-positive bacteria showed good sensitivity to most of the antibiotics. It showed good sensitivity for amikacin, gentamycin, amoxyclav, ofloxacin, ciprofloxacin and vancomycin. E. coli, Pseudomonas spp., and Staphylococcus aureus were the most common cause of infections. Most isolates were multi-drug resistance.

In this paper the existence of odd and even ratio edge antimagic labeling for double triangular snakes (2?k-snake), 2m?1-snake, 2m?k-snake and kC4-snake are proved.

This experiment is a continuation of our effort to develop drug delivery carrier of Gum Arabic GA (Acacia Senegal) gum Arabic-g-3,3-dimethyl acrylic acid for a cancer. The effect of graft reaction conditions on the percentage of graft efficiency and percentage of graft yield in the graft copolymerization were investigated. It was observed that grafting parameters such as 3,3-dimethyl acrylic acid, ceric ammonium nitrate (CAN), Gum Arabic (GA), temperature and reaction time have remarkable influence on the percentage of graft efficiency and percentage of graft yield of the graft copolymer. Optimum the percentage of graft efficiency and percentage of graft yield were (26%) and (75.5%). Evidence of grafting was confirmed by comparison of FTIR spectra of GA, 3,3-dimethyl acrylic acid and the grafted copolymer as well as scanning electron micrography (SEM), Thermogravimetric analysis (TGA) and X-ray diffraction of the product.
