Presentation1REVIEW
The document discusses the need to migrate OPC applications from a DCOM-based architecture to a more secure .NET-based or service-oriented architecture (SOA). Currently, SAIL's internal network connecting its production units is indirectly connected to the public internet. This exposes programmable logic controllers (PLCs) to attacks like Stuxnet since OPC servers use DCOM technology which cannot route through firewalls.

Wound healing PPT
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.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
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

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.

- 1. WEB SERVICES Bhargav Tailor bhargavtailor6@hotmail.com 9974218047
- 2. WHY WEB SERVICES NEEDED …………..? While creating a website that display Local, national and International news to its user . So that you do not have enough resource and budget to collect the latest news and keep the content of website up-to-date. we can easily do this , we can gather the news from other News websites and simply display on our websites We can do this easily with the help of Web services , Which allow your website to communicate with the other News websites
- 3. WHAT IS ACTUALLY WEB SERVICES..? A web services is an entity that can be programmed to provide a particular functionality to any number of application over the internet Web services can be use by any web application , no matter whatever programming language is used or hardware platform and operating system on which application is running Web services does not have any user interface . It just provide s specific services to website Before web services is introduce there is many technologies are used such as DCOM and CORBA but web services is more popular
- 4. FULL FORM OF DCOM & CORBA DCOM : - Distributed Component Object Model CORBA : - Common Object Request Broker Architecture
- 5. [CONT..] Web services are most appropriate to be used while communicating across cross-platform or making trusted connection between server and the client
- 6. BENEFITS OF WEB SERVICES It is simple because of which they can be implemented on various platform Web services is loosely coupled because of which their interface and methods can be extended Web services do not carry any state information from web pages
- 7. HOW CALL WEB SERVICES METHOD…?
- 8. WEB SERVICES COMPLIES WITH COMMON INDUSTRY STANDARDS .. Simple Object Access Protocol (SOAP) Web Services Description Language (WSDL)
- 9. SOAP (SIMPLE OBJECT ACCESS PROTOCOL) SOAP allows web services to communicate with other Web Application over the Internet . SOAP is a simple XML-based Protocol to let exchange information over HTTP. SOAP is a Protocol for accessing Web services . SOAP Specifies a format for the XML Message using which the web application request and receive we services from a web Server
- 10. TWO FEATURES OF SOAP SUPPORT FOR THIS [CONT..] Remote Procedure Calls : Remote web application sends a SOAP message that contains a request to a Procedure of Web services . Platform Independent : Web services can be developed using any programming language not necessary to use same language used in web application
- 11. WSDL (WEB SERVICES DESCRIPTION LANGUAGE) WSDL allow consumer of a Web services to know about the web services before interacting with it. It describe all the information required to use a Web services that are Following. Operation : Refer to the mechanism used by the web services to exchange message with the consumer of the web services. Bindings : Refer to the protocol used by the web service to the interact with consumer of the web services . Endpoint : Refer to the Location of a Binding.
- 12. [CONT..] We can use WSDL to describe a web services with the help of XML therefore you can use WSDL to describe a web services that can be used by the application create using different platform and programming language . WSDL is a document written in XML. The document describes a Web service. It specifies the location of the service and the operations the service exposes.
- 13. MAJOR ELEMENT OF WSDL [CONT..] <type> : A container for data type definitions used by the web service. <message> : A typed definition of the data being communicated. <portType> : A set of operations supported by one or more endpoints. <binding> : Describe how a protocol can be used with particular Interface
- 14. LOCATING WEB SERVICES.. The URL of the web services that you want to use in your application , so you will just place it in a configuration file . In other situation you might have to search URL of the Web services at application runtime . There is two method to search URL for web services. DISCO (Discovery) UDDI (Universal Description ,Discovery and Integration)
- 15. DISCO.. It a standard that creates a list of related web services in a file, called DISCO file . An Organization can publish its own DISCO file on the server, so that client can accessed this file to determine what all web services are available
- 16. UDDI It a Centralized directory where different Web services offered by different Organization are published Client can Search required Web services in the Directory
- 17. THANK YOU
