A SPATIAL ANALYSIS ON THE PROVISION OF URBAN PUBLIC SERVICES AND THEIR DEFICIENCIES: A STUDY OF SOME SELECTED BLOCKS IN KHULNA CITY, BANGLADESH

In most of the cities in Bangladesh, there is a considerable lacking in providing public services comparing with the demand. This study aims to identify the deficiencies in providing public services in three selected blocks of Khulna city, Bangladesh. Blocks are considered here as an individual small administrative unit within the jurisdiction of Khulna City Corporation. First the study identified the spatial concentration of the services among the blocks. The comparative situation of the blocks in terms of public services was viewed by location quotient method and Gini coefficient and neighbourhood standard were consider to identify the deficiencies. The study found that two of the blocks are comparatively developed while the other one lag far behind the mean level of development of the city. Lastly on the basis of population and space standard, required facilities for each of the blocks were calculated.Urban Services, Defficiencies, Spatial Analysis, Khulna City.

Wave overtopping and toe scouring at a plain vertical seawall with shingle foreshore : a physical model study

This paper describes a physical model study to investigate the wave overtopping and toe scouring at a plain vertical wall with a shingle foreshore. A matrix of 180 experimental test conditions were performed in a 2D wave flume, with an approximate scale of 1:50. The study investigates the baseline overtopping characteristics at a plain vertical wall on an impermeable 1:20 foreshore slope and compares the results with two permeable 1:20 shingle beach foreshores with prototype d50 values of 13 mm, and 24 mm respectively. For impulsive wave conditions, it was found that the mean overtopping rate was reduced by factor 3 for the d50 of 13 mm, and a factor of 4 for the d50 of 24 mm. For non-impulsive waves, the reduction factors were 1.5 for d50 of 13 mm and 2 for d50 of 24 mm. Prior to this study, limited design guidance was available to predict the mean overtopping discharges and mean sediment rates at vertical seawalls on permeable shingle foreshores. Therefore, a new set of prediction formulae are proposed in this study, based on the new laboratory test results, and a comparison with the available prediction methods in literature for vertical seawalls subjected to both impulsive and non-impulsive wave conditions

Experimental study on toe scouring at sloping walls with gravel foreshores

Sea defences, such as urban seawalls can fail due to the development of a scour hole at the toe of the structure. The scour depth or the information on ground levels at the structure toe is required for the sustainable management of coastal defences, due to its influence on the structural performance. This research reports and summarises the main findings of a new laboratory study on toe scouring at a smooth sloping wall with permeable gravel foreshore. A set of small-scale laboratory experiments of wave-induced scouring at sloping seawalls were conducted. Two gravel sediments of prototype d50 values of 13 mm and 24 mm were used to simulate the permeable 1:20 (V:H) gravel beach configurations in the front of a smooth 1 in 2 sloping wall. Each experiment comprised of a sequence of around 1000 random waves of a JONSWAP energy spectrum with a peak enhancement factor of 3.3. The relationship of the scour depth with toe water depth, Iribarren number, and wall slope were investigated from the test results of this work and through a comparison with available datasets in the literature. The results of this study showed that the relative toe water depth and Iribarren number influence the relative toe scour depth at a sloping structure on a shingle beach. Within the experimental limitations, the maximum toe scour depths were observed for the experiments under spilling and plunging wave attack

Determinants of Structural Change in the Dairy Sector

Even though the dairy products are not a staple food item, but they are necessary for humans as an excellent source of protein. The consumption of dairy commodities began a long time ago, and over time there has been an improvement in the processing to match the changes in the tastes. Small scale dairy production was the root of today’s dairy sector. However, now it is going on a large scale. This changed gradually through a process accompanied by different factors. This study aimed at identifying and understanding existing determinants and their role behind the change in the dairy sector. For this, peer-reviewed articles published by researchers around the world were obtained with all possible search combinations from reputed online databases. Statistical data were collected from reliable statistical data providers, and all activities were done focusing on the determinants of changing the dairy sector. The regulatory policy framework of dairy-producing countries, change in farm size, shift in consumption pattern, etc. were found as the most crucial factors behind the change. Possible suggestions required to keep pace with this massive change were discussed

A Brief Concept of Cell Culture: Challenges, Prospects and Applications

DEVELOPMENT OF COST-EFFECTIVE FAULT LOCALIZATION PLATFORM FOR UNDERGROUND CABLE SYSTEM

The mining industry is highly dependent on electricity or other forms of energy converted into electricity. Here, one of the common forms of electricity distribution is through underground cables, but the electricity systems regularly confront contingencies due to cable breakdowns or defects. Depending on fault types, detective tools, and cable position, it may take several hours to days to detect the exact fault location with existing methods and tools, which affects the entire mining operation with financial losses and safety issues. Besides, industrial fault localization platforms are very expensive and seldom tailored for the mining industry. To locate such faults, the online fault localization platform has drawn wide attention but is limited in functionalities and applications. This research aims to develop a cost-effective double-ended online fault localization platform while proposing solutions for data synchronization and accurate traveling wave arrival time detection problems. At first, extensive market research has been done on available platforms to access those platforms’ functionalities and costings. Then, a hardware setup has been developed by combining appropriate sensors, a data acquisition unit, a computational platform, and other necessary components. Furthermore, to establish communication between remote platforms, a Python-based software program has been developed. Besides, query-based server management has been introduced to handle and manage huge amounts of data. Combining the hardware and software, the overall cost of a single platform is CAD $ 2,850.00, which is at least ten times less than the least expensive market option. The chosen double-ended traveling wave-based online fault localization method requires accurate synchronized time to properly compute the traveling wave arrival time difference. Thus, coordinated universal time alignment of acquired time series data is needed. Global Positioning System (GPS) based universal time synchronization is one of the popular ways. There are several other techniques, but all of these have some practical difficulties and dependencies. To solve this problem, a cost-effective novel zero-crossing point-based data synchronization approach has been proposed. This approach doesn’t rely on GPS receivers or any other existing methods; rather, the measurement is synchronized by calibrating the zero-crossing points of the sinusoid measurements before the fault. In this way, appropriate synchronization has been realized. The accuracy of traveling wave-based fault localization highly depends on how accurately its arrival times are detected from ends of cable. Accurate detections are achieved when signals sampling rates are high. Usually, a data acquisition system with a higher sampling rate may address the issue, but it increases cost. On the other hand, available interpolation-based up-sampling techniques have several constraints. Machine learning model can solve this problem if trained by real inputs and outputs with desired sampling rates for different types of faults. In this research, a machine learning-based up-sampling model has been presented, which improves the accuracy of traveling wave arrival time detection. Besides, it is cost-effective and outperforms interpolation techniques. Therefore, the proposed fault localization platform combines all the above solutions, which makes the platform very advance, reliable, and cost-effective

Multiple cavitating cannon ball metastasis with primary adenocarcinoma lung: a rare case report

Multiple large round well circumscribed pulmonary nodules in lungs are known as cannon ball secondaries. There are malignant and non-malignant causes of cannon ball secondaries. In case of malignancy, they represent classical haematogenous dissemination to the lungs of a primary malignant tumor. Secondaries to lung from renal cell carcinoma and choriocarcinoma are necrotic. The less common primary tumors causing cannon ball secondaries to lung includes prostate carcinoma, synovial sarcoma, endometrial carcinoma and some gastrointestinal malignancies. Here we presented a very rare case, maybe first of its kind of multiple cavitating cannon ball secondaries where primary malignancy was in lung itself which was EGFR positive adenocarcinoma lung. This case was also rare as cavitation is largely a feature of squamous cell carcinoma lung both of primary and metastatic lung malignancy
