The highly variable microbiota associated to intestinal mucosa correlates with growth and hypoxia resistance of sea bass, Dicentrarchus labrax, submitted to different nutritional ...

Background The better understanding of how intestinal microbiota interacts with fish health is one of the key to sustainable aquaculture development. The present experiment aimed at correlating active microbiota associated to intestinal mucosa with Specific Growth Rate (SGR) and Hypoxia Resistance ...

BAC-pool sequencing and analysis confirms growth-associated QTLs in the Asian seabass genome

The Asian seabass is an important marine food fish that has been cultured for several decades in Asia Pacific. However, the lack of a high quality reference genome has hampered efforts to improve its selective breeding. A 3D BAC pool set generated in this study was screened using 22 SSR markers located ...

Occurrence of OsHV-1 in Crassostrea gigas Cultured in Ireland during an Exceptionally Warm Summer. Selection of Less Susceptible Oysters

The occurrence of OsHV-1, a herpes virus causing mass mortality in the Pacific oyster Crassostrea gigas was investigated with the aim to select individuals with different susceptibility to the infection. Naïve spat transferred to infected areas and juveniles currently being grown at those sites were ...

Coiled Tubing Telemetry System Improvements with Real-Time Tension, Compression, and Torque Data Monitoring

Abstract Real-time depth, pressure, and temperature data monitoring is currently available for well interventions with coiled tubing (CT). A recently-developed extension for real-time forces (i.e., tension and compression) and torque data monitoring has been added to a robust CT telemetry (CTT) system, ...

Well Integrity Assessment Using Video Camera Technology - Case Histories

Abstract Video technology has been used worldwide in various applications, including situations that require diagnosis and evaluation. Advances in video equipment have led to the development of downhole video cameras that are capable of working in the harsh environments encountered in the upstream ...

Optimizing LNG Cooling Water System Performance-Biofouling Control Through Pulse-Chlorination®

Abstract Abu Dhabi Gas Liquefaction Company Ltd (ADGAS) owns and operates three LNG trains at DAS island. Trains 1 and 2 have common utilities while train 3 has a separate utilities system. The three LNG trains have a once-through sea cooling water (SCW) system which includes a series of heat-exchangers. ...

Variations on a theme: Genomics of sex determination in the cichlid fish Astatotilapia burtoni

Background Sex chromosomes change more frequently in fish than in mammals or birds. However, certain chromosomes or genes are repeatedly used as sex determinants in different members of the teleostean lineage. East African cichlids are an enigmatic model system in evolutionary biology representing ...

De novo assembly and analysis of changes in the protein-coding transcriptome of the freshwater shrimp Paratya australiensis (Decapoda: Atyidae) in response to acid sulfate ...

Background The atyid shrimp Paratya australiensis occurs in surface freshwater habitats throughout eastern Australia and has been used to study the ecotoxicology of contaminants such as pesticides and metals. The acidification of surface water that can occur after acid sulfate material in soils and ...

Application of Ultrashort Radius Lateral Drilling Technique in Top Thick Reservoir Exploitation after Long Term Water Flooding

Abstract Numbers of oil fields in China had entered high water cut stage. The inefficiency circulation happened frequently during water flooding of these oil fields because of seriously intraformational heterogeneity in thick reservoir. Based on oilfield development dynamic data, it indicated that ...

Novel Approach to Restore Integrity to Downhole Safety Valves from Damaged Landing

Abstract Well Integrity management standards require wells to be equipped with two independent barriers to protect against uncontrolled flow of hydrocarbons from the reservoir to the environment. For producing wells the two barriers are usually the downhole safety valve and the surface X-mas tree. ...

Well Integrity Assessment Using Video Camera Technology - Case Histories

Innovative Wireline X-Ray Diagnostic Service Reduces Risk During Well Interventions: A Case Study

Abstract During well intervention activities, one of the biggest challenges faced is uncertainty about the downhole hardware. Carrying out interventions without understanding the state of downhole equipment can be time-consuming, expensive and ultimately unsuccessful. There are several diagnostic techniques ...

Sandstorm Contingency for Logging with Coiled Tubing: Coiled Tubing Cut, Site Evacuation and Safe Recovery - Success Story from Middle East Field

Abstract Objectives/Scope: Operations in onshore fields at UAE are affected during the months of March through June by the weather, as sand storms are created and attack the area, there is always a need to plan abandonments to avoid harm to any personnel, environment and minimize damage to facilities. In ...

Moving the Oil and Gas Sector into the Video Age: Vision Assisted Well Interventions Reduce Cost and Add Value

Abstract Economic challenges, within the oil and gas industry, make the optimization of production from existing wells more important than ever. Increasing the number of active wells and maximizing their production can be achieved through integrity-restoring and production-enhancing well intervention ...

Relationship between antibiotic resistance genes and metals in residential soil samples from Western Australia

Increasing drug-resistant infections have drawn research interest towards examining environmental bacteria and the discovery that many factors, including elevated metal conditions, contribute to proliferation of antibiotic resistance (AR). This study examined 90 garden soils from Western Australia to ...

Edwardsiella tarda OmpA Encapsulated in Chitosan Nanoparticles Shows Superior Protection over Inactivated Whole Cell Vaccine in Orally Vaccinated Fringed-Lipped Peninsula ...

The use of oral vaccination in finfish has lagged behind injectable vaccines for a long time as oral vaccines fall short of injection vaccines in conferring protective immunity. Biodegradable polymeric nanoparticles (NPs) have shown potential to serve as antigen delivery systems for oral vaccines. In ...

The 2nd International Conference on Water Resource and Environment (WRE 2016)

Table of contents 01 The eco-toxicological effects of cadmium stress on five ornamental plants Zhouli Liu, Wei Chen, Xingyuan He, Shuai Yu, Weihang Ding 02 Study on the formation and release mechanisms of hydrogen sulfide in Longtan coal mine Jianjun Liu, Yuliang Wu, Kaixiang Fan 03 Coral bleaching ...

Different Relationship between hsp70 mRNA and hsp70 Levels in the Heat Shock Response of Two Salmonids with Dissimilar Temperature Preference

The heat shock response (HSR) refers to the rapid production of heat shock proteins (hsps) in response to a sudden increase in temperature. Its regulation by heat shock factors is a good example of how gene expression is transcriptionally regulated by environmental stresses. In contrast, little is known ...

Electrochemical Affinity Biosensors Based on Disposable Screen-Printed Electrodes for Detection of Food Allergens

Food allergens are proteins from nuts and tree nuts, fish, shellfish, wheat, soy, eggs or milk which trigger severe adverse reactions in the human body, involving IgE-type antibodies. Sensitive detection of allergens in a large variety of food matrices has become increasingly important considering the ...
