Biological indices based on the biomass (dry weight, ash content, and chlorophyll-a) of the periphyton in a natural (submersed leaves of Typha domingensis Pers) and in an artificial (plastic hoses) substrate were compared, in experiments performed in summer and winter, in two sampling stations of Imboassica Lagoon, Macaé, Rio de Janeiro. The periphytic community exhibited low biomass at the beg...

in this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of iran. four stations in khuzestan- abadan, hosseyneh, mahshahr, and shushtar- are analyzed to determine the potential of wind power generation in this province. from the primary evaluation and by determining mean wind speed and also the weibull funct...

It is always difficult to measure the emission spectrum of a thermoluminescent material, because the emission is transient, of low intensity, and the spectrum may change from one glow curve to another. Methods used in the past have involved making extremely fast spectral scans 1 , or heating multiple samples and recording a single wavelength band for each sample. 2 The second method is very tim...

background several studies have investigated the effect of acupressure on pain and vital signs however the results are inconsistent. either no study has been conducted on the effect of acupressure on vital signs of post-surgical patients, or it is not available. objectives the present study was conducted to assess the effects of p6 acupressure on pain and vital signs of patients following small...

Narta Lagoon is one of the biggest Lagoons in Albania. It situated southern part Vjosa River delta. Two canals northwest and southwest parts lagoon connect it to Adriatic Sea. These artificial enable water exchange process with sea during tidal flow. Vjose - area considered a Protected Landscape, so environmental monitoring important. Setting design: Water samples were taken monthly, at six eve...

Sediment samples were collected in the Gulf of Gdańsk, and the Vistula and Szczecin Lagoons-all located in the coastal zone of the Southern Baltic Sea-just after the total ban on using harmful organotins in antifouling paints on ships came into force, to assess their butyltin and phenyltin contamination extent. Altogether, 26 sampling stations were chosen to account for different potential expo...

wetlands are often considered sinks for contaminants, and aquatic plants have been shown to play important roles in wetland biogeochemistry through their active and passive circulation of elements. in this research, in order to evaluate the concentration level of heavy metals released by the urban, industrial and agricultural activities at the margin of the rivers flowing into anzali lagoon, as...

Venice Lagoon has a complex relationship with the many economic activities it hosts: tourism, oil refineries, a logistics hub, agriculture, households, and fisheries heavily affect the condition of the lagoon. At the same time, they all strongly rely on the environmental services it provides. Against a situation where each economic sector is simultaneously cause and victim of such “disturbances...
