Fish farming is a fundamental sector of the economy for several communities. Traditionally, the processes inherent to this activity, such as the feeding of the fish, the replacement of water, the control of temperature, the level of ammonium, are carried out manually and empirically; However, in recent years they have begun to incorporate technological tools for their automation. In the present work we seek to integrate intelligent and separate control systems that exist in the market to generate a single intelligent control system, with the ability to control temperature, ammonia, water clarity, food, in such a way that is presented as a flexible and integrated production process, that meets the requirements of aquaculture health, this system should provide, to small producers in the southern area of the State of Mexico, the certainty that your product meets specifications and standards for human consumption. With this study new opportunities for the application of technologies, especially those of low cost, are envisaged, so that they are accessible to the greatest number of fish farmers and their use guarantees the improvement in the processes carried out. It also highlights the importance that the use of alternative energies can have, to make the most of natural resources and minimize the environmental impact.

Cage Fish

Cage fish farming in Indian reservoirs has the potential to enhance the reservoir production manifold. The present study estimated that around 14,000 cages have been installed in different reservoirs of the country which are producing around 16% of the current reservoir fish production. Around 7.5 lakh mandays of labour are being generated by cage fish farming in the country. An empirical study in the state of Jharkhand State found that the adoption of cage culture contributed around 30% to the livelihood of fishers. Cage culture not only increased monthly family income but also reduced the occupational migration. The fishermen households who adopted cage farming also accumulated some durable assets due to improvement in household income. However, high initial cost of cage culture operation, high feed cost and low market price of cultured pangas fish (Pangasianodon hypophthalmus) were some of the major constraints in adopting the technology as reported by the fishers. The study recommends that the state departments need to promote the use of low cost galvanised iron(GI) cages designed by the ICAR-Central Inland Fisheries Research Institute (ICAR-CIFRI) in reservoirs which may play a significant role in fulfilling the vision of blue revolution in the country.

Used Atmega 8 microcontroller as the control center, with the temperature sensor DS18B20, feeding control system, combined with radio frequency technology, intelligent control system for fish-farming was designed. The system has the whole process of intelligent automatic control and testing for feeding, supplemental oxygen, and PID temperature regulation; PC and the host processor connect each other through the RS-485 to greatly improve the transmission distance, using CRC cyclic redundancy check code ensure the accuracy of data. The machine is mainly responsible for collecting the spot parameters such as temperature and transmitting the data to the host processor, and send data to PC by the host processor through the serial port to display. Using GSM short message service directly sends the relevant data to the console or the owner of the mobile phone, so as to realize the entire fish process automation management. The system can be widely used in families, and pond pisciculture, and provides the owners efficient and convenient services.

The article provides an analysis and systematization of the reasons for abandoning trains, highlighting the main reasons, as well as factors of the first and second levels. At present, intelligent systems are undergoing great development. Such a system is an intelligent control system for railway transport. Savings, if used according to the calculations, will be significant. Also, a large number of receiving and departure tracks at intermediate stations are freed, which will increase the efficiency of the railway performance, as well as reduce the losses of shippers. In conclusion, it is concluded that an integrated approach is needed from the side of the logistics component and from the side of the organization of train traffic.

With the rapid development of the Internet, the remote control technology was demanded more. In this paper, we designed a simple and practical remote intelligent control system, using CGI technology to complete the construction of Web servers and embedding uCOSII as the real-time operating system in Cortex-M3 core processor. By porting TCP/IP protocol stack, users could login in the server to access and control the system via the Internet. Using NRF2401 wireless technology to build a terminal network, the terminal carried out intelligent control with field data collected by sensors. Meanwhile, users could make monitor and control on a control terminal via a Web browser on a PC or mobile. The remote intelligent control system was stable, real-time, low cost, fit for the smart home, industrial remote monitor and so on, so it would have a better application prospects.

Artificial Aeration

Abstract Fluid mechanics is one of the oldest areas of physics with the greatest number of applications in everyday life. This area became more versatile when mass and energy transport equations were incorporated. Together, these equations allow describing a wide variety of case studies with great precision. Among cases available in the open literature, aquaculture is one of the most important due to the growing need for food sources for human consumption, the nutritional value of many fish varieties, the low cost of the maintenance of fish farms. Dissolved oxygen is one of the most relevant parameters ensuring water quality in fish farming. Many fish farms use permanent artificial aeration systems for maintaining the oxygen level within the recommended range used, causing an increasing energy consumption. Therefore, this work proposes an equation and validation, based on equations hydraulics and transport phenomenon, capable of determining the maximum concentration of dissolved oxygen in the body from the operating parameters of the tilapia rearing pond.

Public health and safety concerns have traditionally been the main reasons for resisting waste water reuse for fish farming. Potential adverse health effects in such applications could be avoided if the waste is sufficiently treated before reuse. In a full scale demonstration study in Suez, Egypt, about 400 m3/d of raw sewage were treated using a multi-compartment stabilization pond system, for a total residence time from 21-26 days. The treated effluent conformed to WHO guidelines and was used for rearing two types of local fish (tilapia and gray mullet). The produced fish were subjected to an extensive monitoring program. Bacteriological examination revealed that in all samples the fish muscles were free of bacterial contaminants. Nevertheless, low levels of Escherichia coli andAeromonas hydrophila, were isolated from the surface of the fish. Salmonellae, shigellae and staphylococcus aureus were absent from the surface of all the fish sampled. In addition, toxic metals (Pb, Cu, Zn, and Cd) were found to be at much lower levels than the international advisory limits for human consumption. It is concluded that fish reared in the treated effluent at Suez Experimental Station is (a) suitable for marketing for human consumption, and (b) it's quality is equal or better than fresh water fish in Egypt.

Hospital Conversions

The pressures encountered by hospitals in the current era of reimbursement declines and stiffened competition are well known. As the “ultimate” payors—primarily employers and government—aggressively continue to seek low cost care, the response of the hospital industry has been to move toward consolidation and efficiency-enhancing mechanisms.Increasingly, nonprofit, tax-exempt hospitals have come to believe that they are at a significant disadvantage vis-á-vis their for-profit brethren in their ability to attract the capital needed to compete in the market. A growing trend among nonprofit hospitals, therefore, is to sell to or enter into a joint venture with a proprietary organization, or alternatively to convert to for-profit status. In 1995, fifty-eight nonprofit hospitals became for-profit; hospital conversions to for-profit status in 1996 are projected to outstrip the pace established the prior year.The conversion trend has not gone unnoticed at the state level. Recently, several states have proposed or enacted laws regulating sales and conversions of nonprofit hospitals, and many more states are contemplating such legislation.
