In this paper, a capacitance-based design of the tap water flow control device is introduced. It is designed to prevent the waste of water resources caused by the current taps. It collects the capacitance signal by means of C/F conversion module based on 555 timer. Then the switching frequency signal and the flow frequency signal are generated according to the capacitance signal collected. They will be analyzed and compared with the signal STC15F100 microcontroller stored and generating the switch commands and flow regulation instructions to control the step motor. Finally, the water flow control function is realized by the device.

Transmission package delivery can be a problem of routes on the network, one of them is the Wireless network. Mobile Ad-Hoc Network (MANET) topology is often used on Wireless networks. The existence of a malicious node is a threat to MANET. Package delivery uses AODV and AOMDV Protocol Routing in TCP and UDP packet transmission. This study uses a simulation method using NS2, NAM and AWK. The Quality of Service (QoS) parameters used are throughput, packet loss, and jitter. Simulations are carried out using malicious nodes, the results on the AOMDV TCP graph have the highest input values and the best packets but are difficult to minimize energy, while for the TCP jitter values graph is best because it has a flow control function that can adjust the trajectory. The results in AOMDV TCP have the highest input value and the best packet loss but it is difficult to minimize energy, while for TCP value jitters it is best because it has a flow control function that can adjust the trajectory

The flow control function of a flood retention reservoir is taken care of by two double-controlled conical vortex valves. The nozzle diameters of these valves are 900 mm, the diameter of the vortex chamber being 2700 mm. The rate of the outflow to be controlled is up to 8 m3/s. The valves were installed in the spring of 1980 and will be put into service in 1981. Their purpose is to protect a town from floods caused by bad weather.

Attention is drawn to the one side remaining of a nineteenth-century correspondence addressed to Alexander Somerville that is housed in the archives of the Scottish Association for Marine Science at Oban, concerning conchological matters. Previously unstudied letters from James Thomas Marshall shed new light on the practicalities of offshore dredging by nineteenth-century naturalists in the Clyde Sea Area; on personalities within conchology; on the controversies that raged among the conchological community about the production of an agreed list of British molluscan species and on the tensions between conchology and malacology. In particular, the criticism of Canon A. E. Norman's ideas regarding taxonomic revision of J. G. Jeffreys's British conchology, as expressed by Marshall, are highlighted.
