Srivastava and Tandon (1986) during the course of survey for natural enemies of major insect pests of mango at Lucknow, found two entomogenous fungi i.e. Verticillium lecanii Zimm. and Beauveria bassiana (Bals.) Vuill parasitising the mango leafhopper, Idioscopus clypealis Lethierry. Kumar et al. (1983) recorded an entomogenous fungi, Isaria tax parasitising I. clypealis. Nirvan and Upadhyaya (1976), reported V. lecanii to be pathogenic to Amritodus atkinsoni Lethierry. In the present investigations, B. bassiana and V. lecanii and some botanical insecticides were evaluated for the control of A. atkinsoni in a field cage experiment on a Mango (Neelum) tree.Keywords

In wireless LAN technology, access point selection at each station is a critical problem in order to obtain satisfactory throughputs. The traffic load of wireless LANs is often unevenly distributed among the Access Points (APs), which results in unfair bandwidth allocation among Mobile Users. We argue that the load imbalance and consequent unfair bandwidth allocation can be greatly reduced by intelligent association control. In a large wireless network with multiple collocated Access Points (AP), a load balancing policy is necessary for the distribution of the Mobile User (MU) to the APs, so the network performance to be maximized. Already proposed algorithms, which are based only on the Received Signal Strength Indicator (RSSI) and Association Control Algorithm (ACA), may cause all the MU to be associated to a single or to a very few number of APs, and result in an overall network performance degradation. In this paper, we present an efficient solution to determine the MU-AP associations for bandwidth allocation. In this paper, we propose a load balancing procedure namely Optimal Association Control Algorithm (OACA), which acts in two separate levels. First, the APs are either distributed across the channels (if the number of APs is small) or located in the same channel that is specified by taking into account the channel-location and the received RSSI of the neighbor AP. Second, the APs are distributed across all the available MUs, if any MUs relieved from the APs, based not only on RSSI measurements but also on the number of MUs already associated to the AP and other link quality measurements. Besides, in this paper we describe the signaling extension needed for the implementation of the proposed load balancing procedure.

An attempt has been made in this project to use alternative fuel in four stroke engine to increase the efficiency. Our fore most aim in selecting this project is to use non conventional fuel against conventional fuel which is becoming scarce and costly now days. With this environment is less polluted than conventional fuels. It is also good with regard to economical considerations and engine efficiency. In our project, we have installed LPG fuel system to two stroke vehicle where in we can use both gasoline and LPG. The flow of liquid and gaseous fuels is controlled by means of micro controller. The gas comes by means of rubber hose to solenoid valve which operates in D.C. electric current. So a separate battery source is used to operate the solenoid valve. From solenoid valve outlet, separate copper tubes for idle starting and for acceleration are fitted to the carburetor. For lower speeds LPG will be supplied, and gasoline comes into action at higher speed operations. So, these combinations of fuel supply will be suitable for city traffic conditions, where mostly the mode of operation is low speed. Using this concept we can control our expenditure in buying of fuels.Keywords

The Gesell's Drawmg Test of Intelligence is a useful screening tool for research and clinical practice. This cross-sectional exploratory research seeks to compare performance of a purposive sample of 59 children in age range of S- 12 years on the test drawing activity by using computer based Paint Brush Program along with concurrent use of its traditional paper-pencil mode of test administration. Independent scoring by three mutually blinded examiners show no significant difference in scores of subjects between the two modes of administration (p >0.05). However, a consistent pattern of within group differences seen with higher scores for paper-pencil mode of administration on variables like gender, age, residence, type of syllabus, and family background (p 0.05). The findings are discussed with merits and demerits in the ongoing efforts to develop computer-enabled testing devices for children.Keywords

Background/Objectives: Image pre-processing is done for enhancing the features of the input image for efficient image recognition. Image enhancement is done in a series of steps by employing different filtering techniques. Those steps are discussed as follows: Histogram equalization and Normalization. Methods/Statistical Analysis: Research on Identification of Face in a Multifaceted Condition by clustering Enhanced Genetic and Ant Colony Optimization Algorithms. Results: The edge detection of the clipped face image. There are a number of different face recognizing and identification method which varies on different grounds and are employed for different scenarios. Those methods are employed in the system for which FIS is developed and their results are compared. Conclusion/Application: This Face Identification System by clustering Genetic and Ant Colony Optimization algorithm shows the maximum efficiency of 96%. This ACOGA competence can be greater than before by using better face scanner, best technique of scaling and well organized technique of edge detection and feature extraction of the face image. The problems faced while working on this research work are the difficulties in detecting faces of overlapping face images and detecting different face poses.Keywords

Research on home based problem behavior interventions is scarce in Indian settings. This cross sectional random survey aims to identity barriers or facilitators in parent mediated problem behavior interventions for their children. Targeting 78 children between 3-12 years, data was collected as frequency counts of felt, expressed or reported nature, type and extent of challenges, difficutties and issues by respective parents as therapeutic agents. Among their listed 36 types of 918 difficulties, 21 types of 507 issues are linked to service recipients themselves, followed by those viewed as due to the intervention process (Types, 10; N, 293) and few attributed to problems in service providers (Types, 5; N, 118). Disagreements between parents in prioritizing problem behaviors, perception that behavior intervention programs are time consuming, that there is minimal support from spouse and family, or that they expect instantaneous solutions are the most serious barriers. Some parents express hardships in record keeping, admit to pressure of daily routine in caring their unaffected children, the long wait involved in securing appointment from service providers, and the burden of travelling to avail professional help. Follow up and maintenance efforts during planning behavior interventions must necessarily take note of these findings to optimize positive developments in children.Keywords

The present investigation was carried out during 2016-2017 to identify the seed development maturation studies in Barnyard millet cv. MDU 1. The results revealed that seeds attained physiological maturity on 50 days after anthesis as evidenced by the maximum panicle length (30.7 cm), fresh weight (31.2 g), dry weight (23.5g), fresh weight of the seeds (23.4g) and dry weight of the seeds (14.5g). The change of colour of panicle and seed from green to dark brown could be considered as a visible index of maturity. The seed quality parameters viz., germination (51 %), shoot length (9.59 cm), ischolar_main length (18.5 cm) and dry matter (0.025 g/10 seedlings) and vigour index (1175) were also maximum at 50 days after anthesis.Keywords
