Declining marginal profits demand that operating companies and drilling contractors review their practices and examine ways to optimize processes and reduce unplanned expenditures. One area that has been largely overlooked is iron roughneck make up torque. Until recently, most iron roughnecks had no ...
Background: Although there is considerable public concern about the environmental impacts of oil pollution in the Niger Delta of Nigeria, actual evidence on the pathological and psychological effects in the health of local communities is minimally known. We sought to associate the perspective measures ...
Aim: The objective of the study was to isolate and characterize pathogenic Vibrio parahaemolyticus from crustacean shellfishes (crab and shrimp) commonly retailed in coastal parts of eastern India. Materials and Methods: Samples were processed by bacteriological isolation followed by biochemical ...
Large amounts of waste water are discharged daily from the Jeddah Metropolitan Area into the Red Sea. Sewage draining into the Red Sea causes widespread chemical pollution that is toxic to aquatic ecosystems. The objective of this study was to investigate the extent of pollution and assess the presence ...
The combination of a newly developed extreme-tensile-strength steel wireline cable armor and polymer encapsulation technologies has recently created a second generation of low-torque, extreme-strength wireline cables. The high-pull system is complemented with high-capacity winch units for surface data ...
Objectives To describe HIV heterogeneity in rural Uganda using incidence data collected between January 2012 and December 2014 among fishing cohort (FC) and in an adjacent rural general population cohort (GPC). Methods In the FC, eligible HIV high-risk adults aged 18+ years were enrolled, followed ...
Aim: This study was revealed the potential of Peperomia pellucida leaf extract as an immunostimulator agent in controlling motile aeromonad septicemia due to Aeromonas hydrophila in red hybrid tilapia, Oreochromis sp. Materials and Methods: In the present study, minimum inhibitory concentration (MIC) ...
Background MicroRNAs (miRNAs) have emerged as important post-transcriptional regulators of gene expression in a wide variety of physiological processes. They can control both temporal and spatial gene expression and are believed to regulate 30 to 70 % of the genes. Data are however limited for fish ...
Background Enteric diseases affect thousands of Canadians annually and several large outbreaks have occurred due to infection with enteric pathogens. The objectives of this study were to describe the spatial and temporal distributions of reportable Campylobacter, Escherichia coli, Giardia, Salmonella ...
Agriculture research uses “recommendation domains” to develop and transfer crop management practices adapted to specific contexts. The scale of recommendation domains is large when compared to individual production sites and often encompasses less environmental variation than farmers manage. Farmers ...
Vibrio cholerae has caused massive outbreaks and even trans-continental epidemics. In 2008 and 2010, at least 3 remarkable cholera outbreaks occurred in Hainan, Anhui and Jiangsu provinces of China. To address the possible transmissions and the relationships to the 7th pandemic strains of those 3 outbreaks, ...
Climate change and urbanisation of watercourses affect water temperatures and current flow velocities in river systems on a global scale. This represents a particularly critical issue for migratory fish species with complex life histories that use rivers to reproduce. Salmonids are migratory keystone ...
BEFORE THE DAWN of the industrial age, an average UK farm may have had a team of 20 men and 20 horses. As technology progressed and as further advances were made, this might have become 20 men and a tractor. Now, as innovation more usually associated with space exploration is being increasingly adopted ...
Classification of Penaeid prawn species is an important research problem in the area of aquaculture. In literature, many ML algorithms have been proposed for classification. In this paper, performance and usability of penaied prawn species are compared using K-Nearest Neighbourhood (KNN) algorithm, ...
Peninsular India, with its vast and unexplored marine water spread, promises a thriving future for cage farming industry. Nevertheless, the remoteness of cage sites and the characteristic oceanographic upheavals of tropical Indian Ocean, demands several engineering interventions that can ease the level ...
Using mangroves as a potential coastal bioshield has been intensively studied and tested in the past 10 years. Without a doubt, these studies suggest mangroves are able to attenuate waves thus make it perfect bioshield against tsunami, storm surges, erosion and other coastal disaster. This paper synthesis ...
County economy is an important carrier of national economy. In recent years, its importance has got an unprecedented increase with the introduction of main functional zones. Based on Yunnan statistical yearbook and Weishan County's statistical yearbook, this paper applied GIS spatial analysis techniques ...
To solve problems that existed in wired water monitoring system, such as high cost and restricted monitoring water range, a kind of Lijiang River water environment monitoring system is designed based on WSN. In order to ensure long survival time of the sensor node and a high performance of routing node, ...
Electricity theft is a critical issue that needs to be solved. In the future smart meters can immediately monitor the entire system and obtain real-time operating data of a low voltage distribution system. By properly using the data from smart meters, the real-time distribution system model can be established ...
