The Deepwater Horizon oil spill impacted Louisiana's coastal estuaries physically, chemically, and biologically. To better understand the ecological consequences of this oil spill on Louisiana estuaries, we compared the abundance and size of two Gulf shrimp species (Farfantepeneus aztecus and Litopeneus setiferus) in heavily affected and relatively unaffected estuaries, before and after the oil...

The effect of ambient ammonia, hypoxia and combination of both on survival and the physiological and immunological response of the blue shrimp Litopenaeus stylirostris in relation to molt stage was studied. Shrimp were submitted to 44.0-71.5 mg l1 total ammonia-N corresponding to 2.0 mg l1 unionized ammonia NH3-N and/or to 1.5 mg O2 l1 (4.3 kPa) for 24 hours. Survival was recorded and the molt ...

The Zhangwu-Heishan area is located in the east of Fuxin-Yixian basin. Besides Quaternary soil, study mostly covered with volcanic rock. horizon and age rock play an essential role understanding fossil beds, structures, sedimentary evolution West Liaoning Province coal seeking. During this work, 11 samples were measured by SHRIMP U-Pb isotope analysis. Based on reported data Mesozoic Province, ...

The development of flexible electronics operating at radio-frequencies (RF) requires materials that combine excellent electronic performance and the ability to withstand high levels of strain. In this work, we fabricate graphene field-effect transistors (GFETs) on flexible substrates from graphene grown by chemical vapor deposition (CVD). Our devices demonstrate unity-current-gain frequencies, ...

Shrimp production in Thailand has historically been undertaken in the saline and brackish waters of coastal mangroves. In recent years rising demand and prices for shrimp and falling productivity of mangrove areas have motivated an expansion of shrimp production into the fresh-water margins of river estuaries that were previously used for rice cultivation. Generalised additive models, which off...

Background Food allergy is apparently increasing and it is estimated that 3–4% of adults have food allergy. Shrimp is one of the most common causatives in seafood allergy. Patients with shrimp allergy may exhibit life threatening anaphylactic reactions. Tropomyosin is a known important allergen in shrimp. The IgE-binding epitope in shrimp tropomyosin, cross-reacts with other allergenic inverteb...

Vibrio parahaemolyticus culture O from Gulf Coast shrimp was inoculated into whole shrimp and shrimp homogenate to determine its survival at various temperatures and pH values. Although large decreases in viable population occurred during storage for 2 days at 10 to -18 C, survivors were present even after 8 days. No significant differences were observed in the population changes of inoculated ...

Fermentation based on Lactic acid bacteria (LAB) hold great promise for the management of a shrimp biowaste. Although shrimp biowaste is usually dried on beaches it encourages not only environmental pollution but also reduces the recoverable components. Experiments were carried out to test the Paediococcus bacteria for recovery of chitin and carotenoids. Paediococcus acidilactici ATCC 8042 was ...

Among radio amateurs digital meteor burst communication has been discussed for many years. Despite this, no experiments on amateur basis have (to the knowledge of the author) been performed in Sweden or elsewhere in the world. During the past two years several amateurs have reported the random appearance of AX.25 packets from very distant stations. The propagation of these packets can only be e...
