Hydrodynamic modeling and radiotracer investigations in Kolkata Port Trust, Kolkata, West Bengal, India

In this study, hydrodynamic modeling and radiotracer investigations were conducted in Kolkata Port Trust, Kolkata, West Bengal, India to investigate the dispersion of sediments and to evaluate the suitability of three different dumping sites (Upper Auckland, Lower Auckland and Eden) for dredged sediments along a navigation channel. Scandium-46 (148-240 GBq) comprising scandium glass powder with a particle size distribution ranging from 75-100 μm was used as a radiotracer. The radiotracer was injected onto the seabed at the selected site using a remotely operated injection system and its movement on the seabed was tracked over a period of three months using waterproof NaI(Tl) scintillation detector. The tracer concentration curves were plotted on a site map of the area for different trackings and isocount contours were plotted. Qualitative information was obtained from the isocount contours such as the general direction of movement and spread of the radiotracer. The isocount contours showed that the sediment predominantly moved away from the navigation channel. From the isocount, a transport diagram was plotted based on isocount counter and sediment transport parameters such as the general direction of movement by sediments on the seabed, transport velocity, transport thickness and bed load movement rate were determined for all the sites. The dispersion patterns obtained for the sediments by modeling were compared with the experimental results and they were found to be similar. Thus, the model results were validated and the proposed sites were found to be suitable for dumping the dredged material because the sediments did not return to the navigation channel.

USE OF SENSOR TECHNOLOGY TO MAP THE SOCIAL NETWORKS OF PEOPLE LIVING WITH DEMENTIA: A FEASIBILITY STUDY

For older adults living with dementia, social network quality influences health outcomes. However, current social network measurement methods are time consuming and mentally draining for people living with dementia. This study aimed to accurately measure social networks using sensor technology. Bluetooth and radio-frequency identification (RFID) sensors were used to collect social network data in a simulation of a falling nursing home resident living with dementia. Participants wore sensors on their clothing, and video recordings were compared to sensor data. Bluetooth data reflected general direction of movement and instances of idling but were neither precise or accurate. RFID data was accurate after applying data filters. Both systems detected multiple sensors simultaneously. The Bluetooth system is not feasible for clinical use, but the RFID system shows potential for clinical application and accurate measurement of social network factors as interaction frequency and duration.

Characteristics of detection of the general direction of movement of visual objects by preschool-age children with typical and atypical cognitive development

The specifics of functioning of two channels for processing visual information, the magnocellular and parvocellular ones, in preschool children with normal and impaired cognitive development have been studied. Children with delayed psychological development have been found to have a diminished activity in the magnocellular channel due to weakening of the mechanism responsible for assessing the temporal parameters of the visual input. At the same time, children displaying a spectrum of infantile autism syndromes complicated by a delayed psychological development and mental retardation have a pronounced deficit in information processing in both channels of the visual system, manifested in an impaired ability to assess the direction of movement in terms of both temporal and spatial characteristics of the objects. The degree of this impairment is correlated with both the severity of the particular neurological disorder and the level of speech development of the child.

Sediment transport investigation near Sagar Island in Hooghly Estuary, Kolkata Port, Kolkata

A radiotracer investigation was carried out in Hooghly Estuary at Kolkata Port Trust, Kolkata to examine the suitability of a dumping site for dredged sediment located at south of shipping channel. Scandium-46 (300 GBq) as scandium glass powder having the particle size distribution ranging from 40 to 100 μm was used as a radiotracer. The tracer was injected onto the seabed at the site using a remotely operated injection system and its movement was tracked using waterproof scintillation detector. The tracer concentration curves were plotted for different trackings. From the tracer concentration curves iso-activity contours were plotted and parameters such as general direction of movement on seabed, transport velocity, transport thickness and bed load movement rate were determined. The analysis of data indicated that the sediment predominantly moves towards north-east direction during the period of the study and coming in the shipping channel. Based on the investigations, it was found that the proposed site is not suitable for dumping the dredged material, as the movement of sediment is towards the shipping channel.

Seasonal movement patterns of woodland caribou (Rangifer tarandus caribou)

AbstractFor species conservation, defining seasons according to an animal's perception and consideration of seasonal differences in its use of space is required. First, a statistical approach was used to determine seasons based on rates of movement of radio‐collared caribou Rangifer tarandus caribou. Using polynomial regression, five seasons were delineated by inflection points that demarcate changes in rates of movement. Male and female caribou did not differ in timing and number of seasons. Second, the seasons so defined were used to describe the use of space in 33 caribou in north‐western Ontario, Canada. Greatest rates of movement occurred during spring and early winter migration when caribou had both the largest range size and largest distance between seasonal ranges. The general direction of movement was west in spring and east early in winter, although variation occurred among caribou and years. A drop in rate of movement lasting about 3 days may indicate calving. Caribou were most dispersed and occupied the smallest seasonal range during the calving season. The animals showed strong fidelity to calving areas in contrast to the highly variable year‐to‐year location of winter ranges. Understanding the seasons of animal movement patterns, and applying this understanding when developing plans for forest management, may help reduce adverse effects of forest harvesting on highly mobile animals such as woodland caribou.

Detailed Reservoir Analysis using EPT-Cyberlook and Dipmeter Computations: ABSTRACT

In recent years, a tremendous amount of work by oil companies has been done to evaluate tertiary flood programs in heavy oil reservoirs. One of the keys to understanding how a flood will behave, and therefore an input to the modeling, is a basic knowledge of the depositional environment and reservoir geometry. This often requires the analysis of a large amount of information. The core analysis alone on a multiple well project can be extremely time consuming if it is to be done with any significant detail. This paper outlines the basis for a technique which allows a fairly detailed analysis of the reservoir potential and depositional environment. Using field generated Cyberlook logs and the dipmeter programs of Cluster and Geodip, a fairly rapid interpretation can be made which will confirm the depositional environment, the reservoir potential, and the orientation of any permeability barriers within the reservoir. Several examples are presented where the Electromagnetic Propagation log is used in the Cyberlook to identify the mobile oil potential of the reservoir. This computation is then compared to Cluster and Geodip plots and, where anomalies occur, either changes in Rw or oil viscosity are implied. Reservoir geometry is then estimated from knowledge of the depositional environment and the dipmeter computations. With these tools at hand, it is now possible to predict not only which hydrocarbons will move, but the general direction of movement during initial production or flooding of the reservoir.
