Absence of singular superconducting fluctuation corrections to thermal conductivity

We evaluate the superconducting fluctuation corrections to thermal conductivity in the normal state which diverge as T approaches T_c. We find zero total contribution for one, two and three-dimensional superconductors for arbitrary impurity concentration. The method used is diagrammatic many-body theory, and all contributions -- Aslamazov-Larkin (AL), Maki-Thompson (MT), and density-of-states (DOS) -- are considered. The AL contribution is convergent, whilst the divergences of the DOS and MT diagrams exactly cancel.Comment: 4 pages text; 2 figure

Prevalence and detection of cytomegalovirus by polymerase chain reaction (PCR) and simple ELISA in pregnant women

A total of 327 women were screened, amongst them, 7 (2.14%) were cytomegalovirus (CMV) DNA positive by polymerase chain reaction (PCR). Antibodies against toxoplasma were also detected in 106 (32.41%) women, while 54 (16.51%) were anti CMV positive. Eleven (3.36%) and thirteen (3.97%) women were anti HSV and anti Rubella virus positive, respectively. High prevalence was recorded in age group 21 to 30 years which was 2.53% (4/158), followed by the age group <20 years which was 2.27% (1/44), then in age group 31 to 40 years, 2.25% (2/89) CMV DNA were detected by PCR and 0% was recorded in age group of above 40 years. The overall prevalence of human cytomegalovirus (HCMV) infection in 16 to 45 year-old was 2.14% by PCR and the number of abortion noted was 0 to 5 times. Active infection of HCMV was observed in women with number of abortion. Force of infection was significantly higher among age group 21 to 30 and 31 to 40 years. PCR was a more sensitive, reliable and accurate method for the detection of HCMV infection in pregnant women during this study.Key words: Cytomegalovirus, PCR, human cytomegalovirus (HCMV) and ELIS

Interest rate and income disparity: Evidence from Indonesia

We highlight the most adverse impact of capitalism on inequality through the channel of the interest rate. The interest rate has been an instrument of capitalism which aggravates the accumulation of wealth in the hands of very few people and thereby worsens inequality. To this end, this article scrutinises the dynamic impact of financial development on income inequality in the context of Indonesia, applying DOLS and FMOLS approach by analysing time series data over the years of 1984 to 2018. Rising income inequalities has been a common perpetuating trend of East Asian countries among which we find the case of Indonesia worth interesting to study while filling up the gap in the existing literature. We provide evidence that interest rate exacerbates income inequality in the long-run economy of Indonesia. Financial development in the early phases of development favours economic activity in the urban sector based on capital intensive technology which does not help absorb excess rural labour. The empirical finding of this study profoundly demonstrates one of the substantial drawbacks of capitalism in terms of income disparity. © 2020 John Wiley & Sons Lt

MSLICE Sequencing

MSLICE Sequencing is a graphical tool for writing sequences and integrating them into RML files, as well as for producing SCMF files for uplink. When operated in a testbed environment, it also supports uplinking these SCMF files to the testbed via Chill. This software features a free-form textural sequence editor featuring syntax coloring, automatic content assistance (including command and argument completion proposals), complete with types, value ranges, unites, and descriptions from the command dictionary that appear as they are typed. The sequence editor also has a "field mode" that allows tabbing between arguments and displays type/range/units/description for each argument as it is edited. Color-coded error and warning annotations on problematic tokens are included, as well as indications of problems that are not visible in the current scroll range. "Quick Fix" suggestions are made for resolving problems, and all the features afforded by modern source editors are also included such as copy/cut/paste, undo/redo, and a sophisticated find-and-replace system optionally using regular expressions. The software offers a full XML editor for RML files, which features syntax coloring, content assistance and problem annotations as above. There is a form-based, "detail view" that allows structured editing of command arguments and sequence parameters when preferred. The "project view" shows the user s "workspace" as a tree of "resources" (projects, folders, and files) that can subsequently be opened in editors by double-clicking. Files can be added, deleted, dragged-dropped/copied-pasted between folders or projects, and these operations are undoable and redoable. A "problems view" contains a tabular list of all problems in the current workspace. Double-clicking on any row in the table opens an editor for the appropriate sequence, scrolling to the specific line with the problem, and highlighting the problematic characters. From there, one can invoke "quick fix" as described above to resolve the issue. Once resolved, saving the file causes the problem to be removed from the problem view

Mycobiota and aflatoxin B1 contamination of rainbow trout (Oncorhinchus mykiss) feed with emphasis to Aspergillus section Flavi

In the present study, mycobiota and natural occurrence of aflatoxin B1 (AFB1) in pellet feed and feed ingredients used in a feed manufacturing plant for rainbow trout nutrition was investigated. The samples were cultured on the standard isolation media for 2 weeks at 28 ºC. Identification of fungal isolates was implemented based on the macro- and microscopic morphological criteria. AFB1 was detected using high performance liquid chromatography (HPLC). Based on the results obtained, a total of 109 fungal isolates were identified of which Aspergillus was the prominent genus (57.0%), followed by Penicillium (12.84%), Absidia (11.01%) and Pseudallscheria (10.10%). The most frequent Aspergillus species was A. flavus (60.66%) isolated from all feed ingredients as well as pellet feed. Among 37 A. flavus isolates, 19 (51.35%) were able to produce AFB1 on YES broth in the range of 10.2 to 612.8 µg/g fungal dry weight. HPLC analysis of trout feed showed that pellet feed and all feed ingredients tested except gluten were contaminated with different levels of AFB1 in the range of 1.83 to 67.35 µg/kg. Unacceptable levels of AFB1 were reported for feed including soybean, fish meal and wheat. These results indicate the importance of AF contamination of trout feed in amounts higher than the acceptable level as a risk factor for fish farming production

The relationship between learning style preferences and gender, educational major and status in first year medical students: A survey study from Iran

Background: Identifying and employing appropriate learning styles could play an important role in selecting teaching styles in order to improve education. Objectives: This study aimed to determine the relationship between learning styles preferences and gender, educational major and status in first year students at Isfahan University of Medical Sciences. Patients and Methods: A cross-sectional study employing the visual-aural-read/write-kinesthetic (VARK) learning style's questionnaire was done on 184 first year students of medicine, pharmacy, dentistry, nursing and health services management at Isfahan University of Medical Sciences in 2012. The validity of the questionnaire was assessed through experts' views and reliability was calculated using Cronbach's alpha coefficients (α = 0.86). Data were analyzed using the SPSS ver.18 software and x2 test. Results: Out of 184 participants who responded to and returned the questionnaire, 122 (66.3) were female; more than two-thirds (68.5) of the enrolled students were at the professional doctorate level (medicine, pharmacy, dentistry) and 31.5 at the undergraduate level (nursing and health services management). Eighty-nine (48.4) students preferred a single-modal learning style. In contrast, the remaining 95 students (51.6) preferred multi-modal learning styles. A significant relationship between gender and single modal learning styles (P = 0.009) and between status and learning styles (P = 0.04) was observed. Conclusions: According to the results, male students preferred to use the kinesthetic learning style more than females, while, female students preferred the aural learning style. Knowledge about the learning styles of students at educational institutes is valuable and helps solve learning problems among students, and allows students to become better learners. © 2015, Iranian Red Crescent Medical Journal
