Scalable Update Propagation in Partially Replicated, Disconnected Client Server Databases

Proceedings of the Eighth International Conference on Enterprise Information Systems, 2006

Modern databases allow mobile clients, that subscribe to replicated data, to process the replica ... more Modern databases allow mobile clients, that subscribe to replicated data, to process the replica forgoing continuous connectivity, and to receive the updates while connected to the server. Based on the overlap in client interest pattern, the server can do update processing for manageable number of data-groups instead of perclient basis, and hence decouple the update processing cost from the client population. In this paper, we propose an efficient update propagation method that can be applied to a relational database system irrespective of its inherent data organization. We present computationally efficient algorithms for group design and maintenance based on a heuristic function. We provide experimental results that demonstrate that our approach achieves a significant increase in overall scalability over the client-centric approach.

A Study Relating to Diversion of Agricultrual Credit

Though, the share of agricultural sector in gross domestic product (GDP) of India, has reduced from 58 percent (1951-52) to about 17.3 percent (2016-17), still it is considered a decisive driver, in order to achieve 8 to 9 percent growth in GDP. For agricultural development, adequate and timely availability of credit to the farmers is vital and indispensable, as it acts as a catalyst, to move the farmers from traditional to modern agriculture. Agricultural institutional credit has been growing continuously, after the nationalization and other banking sector reforms. But, past experience shows declining trend, in recovery performance of the banks and rural indebtedness, which is affecting adversely the disbursement of agricultural credit. The main reason behind the problem of low recovery is, misutilization of agricultural loan amount, as farmers do not utilize the loan amount, for the purpose for which it is taken. It becomes more dangerous, when agricultural credit amount is utilized for unproductive purposes, which do not generate any income. In light of the above, an attempt has been made in this paper, to analyze the different aspects relating to diversion of loans. The results indicate that, among purposes, 'Buying other inputs' and 'Consumption' are the main purposes, for the diversion of loan followed by 'Meeting social expenses'.

Pant University of Agriculture and Technology. Pantnagar to optimize the NPK doses on rose cv. Super Star under protected conditions for quality flower production and to study the effect of NPK doses on shelf life and vase life of the cut flowers Three levels (0, 30 and 50 gm/m2) each of N, P and K were applied. N,PUKI in first flush and N,P,K, in second flush recorded earliest bud appearance. Potassium significantly decreased the time taken to bud opening. During first flush earliest bud opening was found in N1P,K, combination, while in second flush under N2P1K, combination resulted in earliest bud opening. Maximum number of flowers per bush was found in N1P0K, during first flush and N2P,K1 in second flush. Longer shelf litI was observed under N,P,K2 combination in both first and second flush. Longest vase life was recorded in N1P,K, treatment during first flush.

Localization of resistin and its possible roles in the ovary of a vespertilionid bat, Scotophilus heathi

Immunohistochemical study showed marked variation in resistin immunostaining during different reproductive phases. Most intense immunostaining of resistin was noticed in thecal-interstitial cells in ovary during the period of delayed ovulation, the period of increased androgen synthesis and suppressed ovulation. The changes in ovarian resistin level also correlated positively with circulating leptin level and body white adipose tissue accumulation. The in vitro study showed that resistin alone preferentially stimulated progesterone synthesis, but with luteinizing hormone (LH) stimulated androgen secretion. Resistin alone dose-dependently increased expression of LH-receptor, steroidogenic acute regulatory protein and insulin receptor proteins in the ovary, whereas together with LH showed dose-dependent stimulatory effect on expression of androgen receptor an...

The collaboration is achieved in a distributed manner, and is designed based on peerto-peer computing model. The objective is to provide (1) a decentralized solution, and (2) a near optimal performance with reasonably low overhead. Simulation results are given to demonstrate the performance of the proposed scheme. In addition, the results show that SPACE evenly distributes work loads among participators, and entirely eliminates any requirement of a central cache manager.

A checklist of butterflies of Madhya Pradesh and Chhattigarh states, India

In the year 2000 Chhattisgarh state (CG) was carved out by the division of Madhya Pradesh. The total area of these two states is 43,446km 2 (between 21 0-25 0 N & 74 0 84 0 E; elevation 305-610m) forming about 13.5% of the total geographical area of India. The bulk of Madhya Pradesh and Chhattisgarh lies on the tableland of central India that is bound by the upper Gangetic plains in the north, the Godavari valley in the south, the plains of Gujarat in the west and Orissa and Bihar in the east. Vindhya, Satpura and Maikal hill ranges running east to west and the Eastern Ghats running to the south traverse the two states. The forested area of the two states is 154495km 2 that works out to 34.84% of the total geographic area of the states and also constitutes 20.09% of the total recorded forest area of the country. The forests are well distributed over all the agroclimatic zones. The forest types found in the area are classified as subtropical hill forests, tropical moist deciduous forests, tropical dry deciduous forests and thorny forests. Both the states have several conservation areas; Madhya Pradesh has nine national parks, 25 wildlife sanctuaries, one biosphere reserve, and five tiger reserves; Chhatisgarh has three national parks, 10 wildlife sanctuaries, one biosphere reserve, and one tiger reserve. Studies on the butterflies of central India dates back to

Effect of Aflatoxins on the Changes in Fats and Carbohydrates during Germination and on the Symbiotic Fixation of Nitrogen in Peanuts [Arachis hypogaea]

Free‐reducing sugars increased up to 96 h of germination, and thereafter their concentrations remained more or less constant. However, the rate of formation of free‐reducing sugars decreased with increase in the concentration of aflatoxins. At all the stages of germination the rate of formation of sucrose decreased with increase in the concentration of aflatoxins. The aflatoxins stimulated the fixation of nitrogen during the preflowering stage, leading to an increase in the concentrations of soluble nitrogen in roots and protein in shoots: the maximum amount of total nitrogen fixed and that excreted into the soil was at a concentration of 2.5 μg/ml aflatoxins.

It provides theoretical analysis and empirical evidence from both developing and advanced countries to argue that for many African countries such a development would be a costly irrelevance which they can ill afford; for a number of others, it is likely to do more harm than good. The African countries would do better to use their scarce human, material, and institutional resources to improve their banking systems than to promote stock markets.
