The development of humanity is impossible without means of signaling. Signaling in any sphere of human activity has always been a means of ensuring the safety of his life. One of these areas was railway transport, the development of which and, accordingly, signalling facilities began in the early 19th century.With the progress of technological progress in Russia, signaling tools have also evolved, which have gone from the simplest sound and optical signals to modern ones using satellite technologies. Naturally, this path in the technical evolution of mankind is of interest to scientists and just curious people, since knowledge of the stages of the origin and development of signaling allows contemporaries to improve it and at the same time not forget the basics of this area.As a result of this process, the signaling system on railway transport, its means have undergone serious changes. Primitive ways of giving commands - optical (disk, flag) and sound (whistle) to the participants of the movement were pushed by more modern means of signaling, which already involve microprocessor technology and satellite technologies.An example of modern signaling means is the automatic locomotive signaling of a single row of continuous type (ALS-EN). The signal of this type of signaling is more informative: it contains information about the number of free block sections ahead of the train, as well as about the permissible speed of its movement.

Postharvest Management

Cowpea is an important grain legume widely used as food in Ghana and the world at large. It is a significant protein source used by many people in several countries. However, its postharvest management, especially storage, can be problematic because it is easily attached by storage pest insects, particularly Callosobruchus maculatus. Cowpea storage is crucial as the product is protected against damage and deterioration. Also, it is preserved until such a time that market prices are reasonable before they are marketed, enhancing food security. Cowpea grains that are predisposed to insects often attack significantly reduce the quantity and quality, which renders the product unwholesome for human consumption. A survey will be conducted in Daffiama Bussie Issa District in the Upper West Region of Ghana to identify storage structures and storage protectants used by stakeholders to store cowpea. The cowpea variety to be used for the experiment is called ‘songotra’ and is considered the people’s choice. At the end of the storage period, the physical and chemical properties of the cowpea grains were assessed to confirm whether there is a significant effect on them. Test on the viability of seeds will be conducted. The findings will show which storage structure and protectants proved to be more effective by killing the cowpea weevil and unearth the treatment that will offer the highest and lowest protection. Pairwise Statistical Package for Social Scientists (SPSS) Version 9.0 was used to analyse the survey data. It is recommended that further research is conducted on the quantity of cowpea used for storage with an extended storage period.
