Study on Boiling Heat Transfer Characteristics of R290 in Horizontal Micro-tubes

open access: yesZhileng xuebao, 2020
In this study the boiling heat transfer characteristics of R290 in a 1, 2, and 4 mm horizontal micro-tube were investigated experimentally. The effects of mass flow rate [50-600 kg/(m2?s)], quality (0-1), and heat flux (5-20 kW/m2) on the boiling heat ...

CALCULATION OF HEAT TRANSFER COEFFICIENTS FOR FOODS [PDF]

open access: yesInternational Communications in Heat and Mass Transfer, 2002
ABSTRACT The design of food refrigeration equipment requires estimation of the cooling and freezingtimes of foods and beverages, as well as the corresponding refrigeration loads. The accuracyof these estimates, in turn, depends upon accurate estimates of the surface heat transfercoefficient for the cooling or freezing operation.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

MicroRNA 196a contributes to the aggressiveness of esophageal adenocarcinoma through the MYC/TERT/NFκB axis

open access: yesMolecular Oncology, EarlyView.
mir‐196a promotes Esophagus Adenocarcinoma aggressiveness. On one hand, mir‐196a targets the valosin‐containing protein (VCP) mRNA, causing the accumulation of c‐MYC protein that leads to high amounts of TERT. On the other hand, mir‐196a targets the inhibitor of NFκB (NFKBIA).
