During the long term evolution of globular clusters(GCs), some member stars are lost to the field. The recently found nitrogen-rich(n-rich) metal-poor field stars are promising candidates of these GC escapees, since n enhancement is the fingerprint of chemically enhanced populations in GCs. In this work, we discuss the possibility of identifying n-rich metal-poor field stars with the upcoming Chinese Space Station Telescope(CSST). We focus on the main survey camera with nUV, u, g, r, i, z, y filters and slitless spectrograph with a resolution about *** combination of UV sensitive equipment and prominent n-related molecular lines in the UV band bodes well for the identification: the color–color diagram of(u-g) versus(g-r) is capable of separating n-rich field stars from normal halo stars, if metallicity can be estimated without using the information on u-band ***, the synthetic spectra show that a signal-to-noise ratio of 10 is sufficient to identify n-rich field stars. In the near future, a large sample of n-rich field stars found by CSST, combined with state-of-the-art n-body simulations will be crucial to deciphering GC-Galaxy co-evolution.

Dialectical Thermodynamics’Solution to the Conceptual Imbroglio That Is the Reversible Path

引用

Journal of High Energy Physics, Gravitation and Cosmology 2024年第2期10卷 775-799页

作者： josé C. Íñiguez Independent Researcher Douglas USA

According to the second law of thermodynamics, as currently understood, any given transit of a system along the reversible path proceeds with a total entropy change equal to zero. The fact that this condition is also the identifier of thermodynamic equilibrium, makes each and every point along the reversible path a state of equilibrium, and the reversible path, as expressed by a noted thermodynamic author, “a dense succession of equilibrium states”. The difficulties with these notions are plural. The fact, for example, that systems need to be forced out of equilibrium via the expenditure of work, would make any spontaneous reversible process a consumer of work, this in opposition to common thermodynamic wisdom that makes spontaneous reversible processes the most efficient transformers of work-producing-potential into actual work. The solution to this and other related impasses is provided by Dialectical Thermodynamics via its previously proved notion assigning a negative entropy change to the energy upgrading process represented by the transformation of heat into work. The said solution is here exemplified with the ideal-gas phase isomerization of butane into isobutane.

Temperature Trends and Accumulation of Chill Hours, Chill Units, and Chill Portions in South Carolina

引用

Atmospheric and Climate Sciences 2024年第2期14卷 173-190页

作者： josé O. Payero Edisto Research and Education Center Clemson University Blackville SC USA Department of Agricultural Sciences Clemson University Clemson SC USA

There is considerable concern about the potential impact of climate change on agriculture, such as the accumulation of chilling hours needed to break the dormancy of many perennial plants, like fruit trees. Therefore, this study aimed to determine if there had been a significant change in air temperatures and chill hours, chill units, and chill portion accumulation in South Carolina over the last two decades. Two decades of daily maximum (Tmax) and minimum (Tmin) air temperature records were obtained from weather stations in thirty-one counties in South Carolina. Hourly temperature data, reconstructed from the daily data, were used to calculate the daily and annual chill hours, chill units, and chill portions accumulation using four different chill models for each location and year. The chill models included the T(t) °C model, the 0°C °C model, the Utah model, and the Dynamic model. For each county, regression analyses were conducted to evaluate the historical trends. Despite year-to-year variability, the tendency was a statistically significant (α = 0.05) increase in air temperature, averaging 0.089°C per year for 20 out of 31 counties in South Carolina. The other 11 counties had no significant change in temperature. The average temperature increase in the 31 counties was 0.072°C per year. The temperature increase resulted in a decrease in annual chill accumulation during the fall to spring, averaging 17.7 chill hours, 8.6 chill hours, 17.0 chill units, and 0.40 chill portions per year calculated with the T(t) °C, 0°C °C, Utah, and Dynamic models, respectively. However, whether this decrease in chill values was statistically significant or not depended on the chill model used. This study did not investigate the cause of the observed historical trends in temperature and chill accumulation. Still, if the trends continue, they could significantly impact the future of the temperate fruit tree industry in the state.

作者： josé Fernando Guadalajara-Boo national Institute of Cardiology “Ignacio Chávez” Mexico City Mexico

In Mexico, digitalis was known since the 16th century and was used to treat patients with bloating, and it was not until the 20th century that it began to be used as a medicine for heart failure. In conjunction with diuretics. Digitalis was later used in combination individualized with the new medications, for this purpose and research has shown that the combination of medications on an individualized basis is what is currently successfully available for the medical treatment of heart failure.
