The Northern snakehead (Channa argus), a member of the Channidae family of the Perciformes, is an economically important freshwater fish native to East Asia. In North America, it has become notorious as an intentionally released invasive species. Its ability to breathe air with gills and migrate short distances over land makes it a good model for bimodal breath research. Therefore, recent resea...
در این تحقیق توانایی سازگاری و میزان رشد یک گونه از ماهیان آب شور (اسکات یا Scatophagus argus)، در محیط آب شیرین مورد بررسی قرار گرفت. 4 تیمار با شوری های 10 و 20 و 30 در هزار و آب شیرین در 3 تکرار انتخاب و هر تکرارشامل 6 عدد ماهی شدند. پس از طی مراحل سازگاری با آب شیرین، از هر تیمار یک ماهی به صورت تصادفی انتخاب گردید و روش های معمول تهیه مقاطع بافتی و رنگ آمیزی (هماتوکسی...
17آلفا- متیلتستوسترون از جمله آندروژنهایی است که در سیکل جنسی نقش دارد و جهت افزایش رشد و تغییر صفات ثانویه مورد استفاده قرار میگیرد. در این تحقیق اثر سه دوز مختلف از این هورمون (300، 400 و 1000 میلیگرم در کیلوگرم جیره) به همراه تیمار شاهد (بدون هورمون) بر خصوصیات ثانویه جنسی (رنگپذیری) ماهی Scatophagus argusبررسی گردید. نتایج این تحقیق نشان داد که ارتباط قوی بین شرایط فیزیولوژیک ماهی با ر...
Purpose Visual scanning by sighted individuals is done using eye and head movements. In contrast, scanning using the Argus II is solely done by head movement, since eye movements can introduce localization errors. Here, we tested if a scanning mode utilizing eye movements increases visual stability and reduces head movements in Argus II users. Methods Eye positions were measured in real-time ...
The snakehead fish Channa argus is an important food fish in China. We identified six microsatellite loci for C. argus. These six microsatellite loci and four other microsatellite markers were used to analyze genetic diversity in four cultured populations of C. argus (SD, JX, HN, and ZJ) and determine their relationships. A total of 154 alleles were detected at the 10 microsatellite loci. The a...
OBJECTIVE The objective was to evaluate magnetic resonance imaging (MRI) issues (magnetic field interactions, heating, artifacts and functional alterations) at 1.5 T and 3 T for the Argus II Retinal Prosthesis (Second Sight Medical Products, Sylmar, CA, USA). MATERIALS AND METHODS Standardized protocols were used to assess magnetic field interactions (translational attraction and torque; 3 T,...
Scale samples of Channa marulius were collected and studied for age determination and calculation of growth parameters. The fish were sampled from Harike Wetland during 1998 to 1999. Linear relationship with a high degree of correlation was observed between total fish length and the lateral scale radius. Age determination studies revealed 5 age groups. The harvestable size falls just below the ...
1. Introduction As the title of this paper shows, the objective of the deliverable is to publish the results of a test on microaggregation techniques implemented in µ-Argus 3.2 using real data and, more specifically, business data, a new aspect in the analysis. Particulary, it has been tested the microaggregation method that, according to the present bibliography, has provided the best results....
A key challenge HCl researchers face when designing a controlled experiment is choosing the appropriate number of participants, or sample size. priori power analysis examines relationships among multiple parameters, including complexity associated with human e.g., order and fatigue effects, to calculate statistical given design. We created Argus, tool that supports interactive exploration power...
