In academic publishing , a scientific journal is a periodical publication intended to further the progress of science , usually by reporting new research. Articles in scientific journals are mostly written by active scientists such as students, researchers and professors instead of professional journalists. There are thousands of scientific journals in publication, and many more have been published at various points in the past see list of scientific journals. Most journals are highly specialized, although some of the oldest journals such as Nature publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that have been peer reviewed , in an attempt to ensure that articles meet the journal’s standards of quality, and scientific validity. Although scientific journals are superficially similar to professional magazines , they are actually quite different.

It is the expression and active agency of a political order and moral economy in which capitalist market forces are treated as unassailable nature. An integral element of that moral economy is displacement of the critique of the invidious outcomes produced by capitalist class power onto equally naturalized categories of ascriptive identity that sort us into groups supposedly defined by what we essentially are rather than what we do.

Patients in ICU are generally 60 years old. Ile de France is now in green area. About 51 new cases have been reported in Val-de-Marne et 49 new cases for , inhabitants over the past few days. Yet, please note that these new cases are rarely followed by hospitalizations so far. As of August 19, , the Parisian region totaled 74 clusters still active, including 30 in Paris. The local health agency gives an update on the situation and we tell you more on the evolution of the number of clusters this week.

A Nature Research Journal. Rechargeable batteries are notoriously difficult to examine nondestructively, and the obscurity of many failure modes provides a strong motivation for developing efficient and detailed diagnostic techniques that can provide information during realistic operating conditions. In-situ NMR spectroscopy has become a powerful technique for the study of electrochemical processes, but has mostly been limited to laboratory cells.
One significant challenge to applying this method to commercial cells has been that the radiofrequency, required for NMR excitation and detection, cannot easily penetrate the battery casing due to the skin depth. This article demonstrates that it is possible to use the battery cell as a resonator in a tuned circuit, thereby allowing signals to be excited inside the cell, and for them to subsequently be detected via the resonant circuit.
Employing this approach, 7 Li NMR signals from the electrolyte, as well as from intercalated and plated metallic lithium in a multilayer rolled commercial pouch cell battery were obtained. Therefore, it is anticipated that critical nondestructive device characterization can be performed with this technique in realistic and even commercial cell designs.

Global declines in insects have sparked wide interest among scientists, politicians, and the general public. Loss of insect diversity and abundance is expected to provoke cascading effects on food webs and to jeopardize ecosystem services. Our understanding of the extent and underlying causes of this decline is based on the abundance of single species or taxonomic groups only, rather than changes in insect biomass which is more relevant for ecological functioning.
Here, we used a standardized protocol to measure total insect biomass using Malaise traps, deployed over 27 years in 63 nature protection areas in Germany 96 unique location-year combinations to infer on the status and trend of local entomofauna.

Increasing consumption of antibiotics is anticipated to drive growth of Global Clostridium Difficile Infection Treatment Market. Global clostridium difficile infection treatment market is expected to witness a significant growth owing to the high prevalence of clostridium difficile infection. It is a leading cause of antibiotic-associated diarrhea worldwide. For example; each year in the United States, about a half million people get sick from C.
Recurrent C. Clostridium difficile also known as C. Illness from C. Its treatment depends on the severity of infection, local epidemiology and type of C. Except for perioperative prophylaxis, it is recommended that the use of cephalosporin and clindamycin be restricted for infection prevention. The development of novel antibiotics and alternative treatment strategies for clostridium difficile infection is gaining a great deal of attention in recent years.

Anyone who has spent more than a few minutes watching some of the more partisan “news” networks lurking in the bowels of cable television is aware that America has grown more polarized in recent years. What’s not so certain is why. In a paper published online March 27 in the Proceedings of the National Academy of Sciences PNAS , a team of researchers at Stanford has devised a mathematical model that helps demonstrate what’s behind the growing rift.
The prevailing sociological theory, known as homophily, is that like seeks like. Those who have similar opinions tend to aggregate together and reinforce opinions that grow more divergent from the center over time. This is the echo chamber model that would seem to gain validation in the era of talk radio, cable news and the Internet. According to this theory, we are polarized precisely because we have greater ability to choose our social networks and news sources.

Officials at the U. Centers for Disease Control and Prevention and epidemic experts from universities around the world conferred last month about what might happen if the new coronavirus gained a foothold in the United States. How many people might die? How many would be infected and need hospitalization?
Studies of previous epidemics have shown that the longer officials waited PNAS. By contrast, Philadelphia took none of those measures; the.
