Block Chaining

Communication via sockets is used to transmit information between applications or between processes over network or locally. ZeroMQ is a library for sending messages using sockets that are quite well known. Talking about sending data, message security is an important part that needs to be taken into account, especially when sending data over a network. ZeroMQ sends messages openly without securing the messages sent. This is evidenced by research which states that ZeroMQ does not have a security layer for sending messages over the network and direct observation of message packets using the wireshark application. Therefore, this study creates a method of securing and authenticating message delivery using AES (Advanced Encryption Standard) CBC (Cipher Block Chaining) mode combined with an authentication method. The AES CBC mode was chosen because it is faster than other methods and has strong encryption. This encryption and authentication are used so that the sender and recipient of the message are both valid senders and recipients so that no message changes during message delivery and messages can only be opened by the message recipient and the sender of the message. Tests are conducted to measure the effect of encryption and authentication on message delivery performance. Based on the tests conducted, there is an increase of 7% from normal delivery speed and the potential for messages is not up to 0.3% - 1.5%.

Private And Public

This paper examines the similarities and differences between public and private ownership of water utilities, including variations such as corporatisation. In any utility where the asset owner and the asset operator are the same, there are pressures to reduce operations and maintenance costs and capital expenditure to maximise returns. The authors argue that this is the case irrespective of whether such returns are to private shareholders or dividends to government. On the other hand, where the asset owner and the asset operator are separate entities with a clearly defined contractual interface, it is not possible to increase returns by reducing operations and maintenance standards, presuming a properly constructed contract. This is because the performance standards are clearly stipulated in the contract with payment reductions applying for non-performance. Such a model can be put in place irrespective of whether the asset owner is a private company or a public utility. The paper examines the profit incentive applying to private and public sector organisations in models where:the asset owner and the asset operator are the same organisation;models where the asset owner and the asset operator are separate organisations, with the service delivery performance governed by a clearly defined contractual interface. The paper shows why the drivers governing the behaviour of public sector and private sector owners are similar, and how the separation of asset owner and asset operator can be used to ensure that service delivery standards are achieved at the lowest cost, whilst providing full transparency to shareholders, regulators and customers alike. The paper also reviews actual comparative data on service quality and performance under a number of ownership and contractual models, and draws conclusions on the effectiveness of the various asset owner/operator models in terms of service delivery performance and costs.

Multistep Process

The poor understanding of the complex multistep process taken by nanocarriers during the delivery process limits the delivery efficiencies and further hinders the translation of these systems into medicine. Here, we describe a series of six self-assembled nanocarrier types with systematically altered physical properties including size, shape, and rigidity, as well as both in vitro and in vivo analyses of their performance in blood circulation, tumor penetration, cancer cell uptake, and anticancer efficacy. We also developed both data and simulation-based models for understanding the influence of physical properties, both individually and considered together, on each delivery step and overall delivery process. Thus, beyond finding that nanocarriers that are simultaneously endowed with tubular shape, short length, and low rigidity outperformed the other types, we now have a suit of theoretical models that can predict how nanocarrier properties will individually and collectively perform in the multistep delivery of anticancer therapies.

The discussion paper analyzes international experience in megaproject management, identifying problems and delivery performance. The most important distortions are optimism bias and strategic misrepresentation. it explores the approaches of Norway and the United Kingdom. Both countries have strengthened the robustness of planning and appraisal for megaprojects and have established specific methods and institutional arrangements for these projects to strengthen governance and transparency. Finally, some lessons are put forward that could help other countries, especially in Latin America, when embarking on megaprojects.
