The main purpose of the present work is to modify and enhance the existing fatigue rig which can be used to perform fatigue experiments on different sections including pipe sections. The structure of this paper is as follows. Section 2 describes the experimental setup used for the fatigue rig, describing the original design and current modifications which includes introducing two new load cells, plastic rollers and sliding flexible jaws to accommodate wide range of section sizes and shapes. Then we describe the instrumentation and data acquisition.

Preliminary studies on conventional estuarine set bag net (CESBN) were carried out during 2016-17 to know the current catch composition. The set bag net is locally fabricated fixed net, normally operated in estuarine region during winter season. The fishing trials were carried out in day time with soaking period of six hours excluding time of setting and hauling. Total of twenty cruises were made for the entire period of study. Results revealed that locally rigged set bag net with 20mm bar mesh size at cod end landed average catch composition of 23.15 kg/haul.

A laboratory test-rig for groundnut planter was developed for testing and calibrating the pneumatic seed metering mechanism. The experimental test rig mainly consists of main frame, seed hopper, seed metering system, power transmission system and sticky belt system. The metering unit is incorporated with a vertical seed plate held in a vacuum retaining chamber to singulate the seeds. A dial type vacuum gauge was provided in order to record the variation in suction pressure. A sticky belt was used to simulate the field surface during laboratory investigation.
