Abstract

The fate and effect of different pollutants entering into the estuaries can be obtained from the existing physico-chemical parameters and it is worthwhile to acquire the hydrographical features of the estuaries at different seasons. This determines the tropic dynamics of the water body. The present study has been made to detail the hydro-geo dynamics of Poonthura estuary. Sewage and retting materials were the main sources of Poonthura estuary. The physico-chemical parameters analyzed include temperature, pH, salinity and alkalinity and dissolved oxygen. The toxic gases hydrogen sulphide, ammonia nitrogen and nutrients viz. nitrite-nitrogen, phosphate phosphorous and silicate-silicon of water samples and the sediment parameters viz. organic carbon, total nitrogen, total phosphorus. From the present study the parameters which are unsuitable for the healthy environment increases during premonsoon due to concentration of pollutants. The winter season showed fewer nutrients with normal level of dissolved oxygen.

Abstract

In morphometry of Pomadasys maculatus, the total length was recorded as 79 mm to 220 mm while mean total length was 162.72 mm in male, whereas total body length in female recorded as 82 mm to 219 mm while mean total length was 173.36. Mean body weight in male was 69.88g, while mean body weight in female was 84.52g. Mean value of Head length in percentage of total body length was found to be 25.32 and snout length was found to be 7.92, Mean value of eye diameter was found as 7.51 and mean value of caudal peduncle length was recorded as 10.07 in male. In female specimens the mean value of Head length in percentage of total body length was found to be 25.87 and snout length was found to be 8.26, mean eye diameter was found as 7.94 and mean value of caudal peduncle length was recorded as 10.49. The meristic characters like dorsal fin rays, anal fin rays, Lateral line scales, gill rakers on lower arm and scales in transversal line were counted. No sexual dimorphism was found in Pomadasys maculatus. In the present study the average total length of females were 152.47 mm TL and the average total length of males were 151.95 mm TL.

Abstract

Nowadays the development speed of the technology is beyond of the human perception. However, every new and innovate profession is not completely safe and sound. How to identify and recognize those work menace and risks is the question that in this study we want to clarify it. There are many methods to concern about risks assessment and here we can refer to Job safety analysis, Safety Audit and etc. What do we mean by Job safety analysis is to put all the processes and activities into a detailed analysis in order to reach the main goal of the work. In this analytical-descriptive study, the vintage is mainly focus on the identification and Job safety analysis of the quay side cranes operator in Imam Khomeini port and offering convenient controlling strategies for reduction and prevention of the probable incidents and unfavorable events. The resulted data of the risks evaluation showed that in the checking level for the facilitating before the start, the risk of the insufficient room in the powerhouse and the body parts contact with the considered items attends the risk priority of 54 and in the discharging level: the risks of the wires cut and falling of the cargo on the stuff and the trucks attends the risk priority of 100 and in the discharging and loading ironware level: the risk of the hook wire cut attends the risk priority of 100 respectively. Finally for each mentioned risk, some suggestive control methods were presented.
