As the development of network the grid will be widely used. To choose a suitable authentication mechanism in a large grid is very important. Identity authentication is one of the important mechanisms that can achieve grid security. It is the first line in the grid applications. It is also a portal in the security system. In the light of the advantages and disadvantages of PKI and ID-PKI, this paper provides a new technology. Presently, PKI and ID-PKI authentication technology is a popular authentication technology. This technology uses the identity certification to reduce the overhead in the domain, and uses CA authentication between domains to guarantee the security of the system.

Control Drug Release

Encapsulation is a process of enclosing the substances within an inert material which protects from environment as well as control drug release. Recently, two type of encapsulation has been performed in several research. Nanoencapsulation is the coating of various substances within another material at sizes on the nano scale. Microencapsulation is similar to nanoencapsulation aside from it involving larger particles and having been done for a greater period of time than nanoencapsulation. Encapsulation is a new technology that has wide applications in pharmaceutical industries, agrochemical, food industries and cosmetics. In this review, the difference between micro and nano encapsulation has been explained. This article gives an overview of different methods and reason for encapsulation. The advantages and disadvantages of micro and nano encapsulation technology were also clearly mentioned in this paper.

Advantages And Disadvantages

Three-dimensional (3D) printing is a recent technology, which gives the possibility to manufacture personalised dosage forms and it has a broad range of applications. One of the most developed, it is the manufacture of oral solid dosage and the four 3DP techniques which have been more used for their manufacture are FDM, inkjet 3DP, SLA and SLS. This systematic review is carried out to statistically analyze the current 3DP techniques employed in manufacturing oral solid formulations and assess the recent trends of this new technology. The work has been organised into four steps, (1) screening of the articles, definition of the inclusion and exclusion criteria and classification of the articles in the two main groups (included/excluded); (2) quantification and characterisation of the included articles; (3) evaluation of the validity of data and data extraction process; (4) data analysis, discussion, and conclusion to define which technique offers the best properties to be applied in the manufacture of oral solid formulations. It has been observed that with SLS 3DP technique, all the characterisation tests required by the BP (drug content, drug dissolution profile, hardness, friability, disintegration time and uniformity of weight) have been performed in the majority of articles, except for the friability test. However, it is not possible to define which of the four 3DP techniques is the most suitable for the manufacture of oral solid formulations, because the selection is affected by different parameters, such as the type of formulation, the physical-mechanical properties to achieve. Moreover, each technique has its specific advantages and disadvantages, such as for FDM the biggest challenge is the degradation of the drug, due to high printing temperature process or for SLA is the toxicity of the carcinogenic risk of the photopolymerising material.

First Line Treatment

The first line treatment in the management of glaucoma is topical medical therapy. Many patients with glaucoma require multiple medications for adequate intraocular pressure control. For patients who need multi-dose regimens to control intraocular pressure, fixed combinations offer convenience, efficacy and safety. This review summarizes the role, efficacy, mechanism of action and indications for use of modern fixed combination of topical glaucoma medications. The review shows the advantages and disadvantages of a prescribing fixed combination in daily clinical practice.

This case weighs the advantages and disadvantages of going global. Ford presented its 1993 Mondeo model, sold as Mystique and Contour in North America, as a “worldcar”. It tried to build a single model for all markets globally to optimize scale of production. This required strong involvement from suppliers and heavy usage of new information technology. The case discusses the difficulties that needed to be overcome as well as the gains that Ford expected from the project. New technology allowed Ford to overcome most of the difficulties it had faced in earlier attempts to produce a worldcar. IT was flanked by major organization changes within Ford. Globalization did not spell obvious success though. While Ford may in the end have succeeded in building an almost global car, it did not necessarily build a car that was competitive in various markets. The Mondeo project resulted in an overhaul of the entire organization under the header of Ford 2000. This program put a heavy emphasis on globalization although it perhaps focused too little on international cooperation and too much on centralization. In terms of Ford’s own history, the Mondeo experience may not be called a new Model T, but does represent an important step in Ford’s transformation as a global firm.

The 12th Five-Year Plan requires the power backbone transmission network to be with large particles and high bandwidth. The new technology-OTN can meet the requests. In addition, OTN makes up for the limitation of small particles transmission of SDH and the defects of WDM networking. Cross is the key technology of OTN. OTN electrical, optical and photoelectrical hybrid cross techniques and their advantages and disadvantages are introduced in this paper. At last, three kinds of cross network strategies are put forward to meet the needs of the future development of Power backbone transmission network, which make the theoretical foundation for the construction of the net.
