...specimens collected from sediments of Mubarak Village in Karachi, Pakistan. The new species is characterized by a cuticle bearing 20-22 longitudinal ridges, tail conical, tapering evenly to narrow terminus 116-128 µm long. Cellular body content extending 2/3 of the tail length. Heterodorus longidens (Jairajpuri and Loof, 1968) Andrassy, 2009 is reported for the first time from Pakistan is briefly redescribed and illustrated.

... Ni, Cd and Pb in water, sediments and different fish species of River Shah Alam, a tributary of River Kabul in Khyber Pakhtunkhwa, Pakistan. The different environmental samples were collected from the river, downstream the city of Peshawar, and analyzed for the selected heavy metals by atomic absorption spectrophotometry. Heavy metal accumulation was studied in muscles of six fish species collected from the river. Heavy metal accumulation was also studied in ...

... in edible fish muscles, sediments and water sampled from Head Punjnad (HP), Pakistan during 2017. The likely reason for the selection of HP as a study target was its emergent prominence as an irrigation hub and holidaymakers spot largely for angling and feasting. The investigated five fish species are Ctenopharyngodon idella, Oreochromis niloticus, Eutropiichthys vacha, Rita rita and Sperata sarwari. The results divulged the...

RE-DESIGNING AND OPERATIONAL ANALYSES OF THE SEDIMENT TRANSPORT CONTROL IN IRRIGATION CANAL NETWORK
...hat this large volume of sediments were deposited due to cross-sectional anomalies along the canal such as the geometry of Reach 2 varied abruptly; at one section the width was 21.54 m and the very next section it faced a contraction and reduced to 16.46 m and at RD 372+638, the width of channel expanded to 45.72 m, which then reduced to 43.28 m. Thus, to make possible efficient flow of water in BRBD Link canal and to decrease the sediment volume, the canal&rs...

...valent to the calculated sediments of 148 tons/ha. Chakwal watershed is acutely facing severe erosion due to its soil characteristics and topography. The outputs generated from this research are a way forward to plan and implement strategies for combating erosion and natural resources protection. It is inevitable to make suitable water harvesting structures and control rainwater to stop soil removal and water provision for the lean season in this rain-fed regi...

... and stagnant water with sediments from different location of Karachi, Sindh, Pakistan. In this study, two genera, Rhabditidoides and Butlerius and three species identified as Rhabditidoides stigmatus, Butlerius micans and Demaniella basili were recorded for the first time in Pakistan. The percentage occurrence of these genera was found as 50% each. These species were identified on the basis of morphological, as well as morphometric characters. In addition, br...

Besides, regional opportunities in Indonesia and Latvia are referred. It was concluded that peat-free soil amendment elaboration can be better implemented on a regional scale after assessing agricultural needs, soil specifics, and available raw material variety applicable as ingredients in soil-improv...

...dy was conducted for the sediments of the Tigris River in Wasit Governorate, Iraq, near the Kut Dam, to determine its chemical, physical and mineral properties. After the soil horizons of the study were determined , samples were taken from each horizon according to the specific depth of each horizon, and the laboratory examination was conducted for the physical and chemical properties. As for the mineral examination, it was conducted for only two depths (surfa...

...tic communities in local sediments influenced by sea-crossing bridge construction. Relatively low levels of alpha diversity and high levels of beta diversity were observed in samples influenced by bridge construction (group EG). The decreased abundance of Chloroplastida and increased abundance of Animalia in group EG suggested that engineering activities induced environmental disturbance, which impaired the ecosystem balance. LEfSe and SIMPER approaches reveal...
