ERP systems are attractive to universities for the same reasons that they are attractive to business organizations: control, accurate information, and centralized systems, all in real time. However, implementing ERP systems at universities has posed some unique problems. By nature, universities are not integrated organizations. Each department operates separately and autonomously, so trying to tie everyone together is difficult enough. Furthermore, university IT personnel are not as experienced as those in large companies, implementations are often rushed, and testing and training often have been inadequate. Universities have been attracted to ERP systems since the mid- 1990 s, when their legacy systems were unable to keep up with increasing technology demands. There were too many legacy systems to maintain, and new systems couldn't be developed in-house because of a lack of staff and experience; ERP seemed like a good alternative. PeopleSoft aggressively marketed to universities and by the end of 2004 had 730 installations in colleges and universities. Some universities have had a particularly difficult time with implementation. Stanford University began its PeopleSoft implementation in 2001. Stanford users complain that completing tasks takes longer than it did prior to the ERP system installation, while the university's IT department complains that the new system is more expensive to support than the prior system. Users at Stanford have been hesitant to adopt the new system, and many of those who are using it are requesting further customization. Lacking widespread use at this stage, the installation of this multimillion dollar system cannot be considered a complete success. Most of the problems related to the PeopleSoft installation are people problems; as with many corporate ERP implementations, the university and its IT department are coping with a tight budget and, consequently, providing little training. Although training was offered to the users, few participated. The University of Massachusetts's PeopleSoft system was down for four days during the critical drop/add period in 2004 , leaving 24,000 students in the lurch. The glitch was traced to a lack of testing. Cleveland State sued PeopleSoft because the college's software was "unusable" and the university had to install an alternative software package to process accounts receivables. In February 2005 , Oracle, which now owns PeopleSoft, settled the suit for $4.25 million. The University of Delaware has taken a slow approach to its PeopleSoft implementation. The first department to use the software was HR, for payroll. The university chose HR because the department is small. The next phase for the implementation was the university-wide financials. The last phase, and the largest phase, has been the student records. There have been a few hiccups, as in all implementations, but in general, it has gone smoothly. Question: 1. Research the PeopleSoft corporation, and explain why its sof.

For this lab, we'll use the javax.crypto libraries in Java. These libraries provide access to a number of cryptographically-related functions, including the ability to encrypt in AES and DES. A skeleton file has been provided called encryptFile.java. The crypt() function The first function we'll complete is the crypt() function. This function takes three byte arrays: an input, which is either a ciphertext or plaintext, a init, which is a 16 -byte initialization vector (for Chaining Block Mode), and a pass, which is a 16 -byte key. It also takes a mode, which is an integer. The Cipher module includes the modes declared as final static integers: Cipher.ENCRYPT_MODE Cipher.DECRYPT_MODE Inside the function, the first thing we need to do is pass the initialization vector and the password.

Endothelial cells sense blood flow and convert biomechanical signals t.docx

Endothelial cells sense blood flow and convert biomechanical signals to cellular biochemical signals and transfer the signals to surrounding perivascular and parenchyma. Other than shear stress, there are different stresses and strains that ECs experience, hence ECs probably have different mechanosensors for corresponding stresses. What are these mechanosensors for the different stresses on vessel walls, and is there any thresholding? .

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP

RAHUL

This Dissertation explores the particular circumstances of Mirzapur, a region located in the core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal environment for investigating the changes in vegetation cover dynamics. Our study utilizes advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to analyze the transformations that have taken place over the course of a decade. The complex relationship between human activities and the environment has been the focus of extensive research and worry. As the global community grapples with swift urbanization, population expansion, and economic progress, the effects on natural ecosystems are becoming more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for these activities. As the most crucial natural resource, its utilization by humans results in different 'Land uses,' which are determined by both human activities and the physical characteristics of the land. The utilization of land is impacted by human needs and environmental factors. In countries like India, rapid population growth and the emphasis on extensive resource exploitation can lead to significant land degradation, adversely affecting the region's land cover. Therefore, human intervention has significantly influenced land use patterns over many centuries, evolving its structure over time and space. In the present era, these changes have accelerated due to factors such as agriculture and urbanization. Information regarding land use and cover is essential for various planning and management tasks related to the Earth's surface, providing crucial environmental data for scientific, resource management, policy purposes, and diverse human activities. Accurate understanding of land use and cover is imperative for the development planning of any area. Consequently, a wide range of professionals, including earth system scientists, land and water managers, and urban planners, are interested in obtaining data on land use and cover changes, conversion trends, and other related patterns. The spatial dimensions of land use and cover support policymakers and scientists in making well-informed decisions, as alterations in these patterns indicate shifts in economic and social conditions. Monitoring such changes with the help of Advanced technologies like Remote Sensing and Geographic Information Systems is crucial for coordinated efforts across different administrative levels. Advanced technologies like Remote Sensing and Geographic Information Systems 9 Changes in vegetation cover refer to variations in the distribution, composition, and overall structure of plant communities across different temporal and spatial scales. These changes can occur natural.

Wound healing PPT

Jyoti Chand

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications. A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function. Healing is the body’s response to injury in an attempt to restore normal structure and functions. Healing can occur in two ways: Regeneration and Repair There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc. Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
