The effect of deep cryogenic treatment on the microstructure, hardness, and wear behavior of D2 tool steel was studied by scanning electron microscopy （sEm）, transm.s.ion electron microscopy （TEm）, X-ray diffraction （XRD）, hardness test, pin-on-disk wear test, and the reciprocating pin-on-fiat wear test. The results show that deep cryogenic treatment eliminates retained austenite, makes a better carbide distribution, and increases the carbide content. Furthermore, some new nano-sized carbides form during the deep cryogenic treatment, thereby increasing the hardness and improving the wear behavior of the samples.

The reaction process during synthesis of Limn2O4 with LiOH·H2O and mnO2 was studied by means of DTA in dynamical air atm.s.here, and it could be applied as an important theoretical principle for preparing Limn2O4. The active energies of four reaction processes were obtained with Doyle-Ozawa method and Kissinger method as follows: 66.299, 72.640, 128.11 and 113.876 kJ·mol-1, respectively. Reaction orders, frequency factors and kinetic equations of each reaction were determined by Kissinger method. XRD, sEm and TEm.s.ow that the synthesized Limn2O4 is a pure phase, with regular appearance and higher ratio-surface.

The scouring around bridge foundations is a significant concern in civil engineering. several research has been conducted experimentally and numerically to study the maximum.s.our depth around the foundations of a bridge in open channel conditions. In cold regions, where ice forms on lakes, reservoirs, and rivers, the interaction between ice and hydraulic structures is further complicated. The flow distribution varies significantly leading to deeper and larger scouring around bridge foundations. The present study took advantage of the data-driven methods to investigate the impacts of ice conditions to maximum.s.our depth. In total, 96 datasets were extracted from previous studies. The m5 decision tree, Genetic Expression Programming(GEP), and Particle swarm Optimization(PsO) were used in data analysis. The models were developed using the train-and-test approach to avoid over-training. The mentioned developed models were further compared with a previous empirical equation associated with the prediction of maximum.s.our depth around piers under ice conditions. Finally, a sensitivity analysis method was applied to evaluate the performance of the data-driven models. It was found that the approaching velocity and pier diameter play the m.s. crucial role in determination of the maximum.s.our depth. The result is generally in agreement with those of previous experimental studies.

Due to the increasing prevalence of clarithromycin resistance, future of management of Helicobacter pylori(H. pylori) infections need to be recognized. To now, clarithromycin was the best effective, well-tolerated and safe antibiotic used in treatment of the bacterium, but, increasing trend of resistance reduced efficacy of recommended regimens. Indeed, gastroenterologists are m.s.ly unable to start appropriate therapyaccording to the sensitivity profile-due to the certain difficulties in routine H. pylori culture procedure and being time consuming method. This announcement by World Health Organization(WHO) was an onset to reconsider current challenging dilemma about H. pylori clarithromycin resistant isolates. Therefore, investigating of various factors affecting this nomination by WHO is highly welcomed. In fact, WHO enumerated more than 16 pathogens which seriously threats human life and public health, thus better management or effective guidelines are necessary. Here for the first time, we nominated this phenomenon as ‘‘gastroenterologist's persistence'' which should be equally investigated as antibiotic resistance. The ability of gastroenterologists to win the game against H. pylori infections is highly influenced by their collaboration with diagnostic laboratories to apply susceptibility patterns before any prescription. In conclusion, closer collaboration between two important partners(gastroenterologists and microbiologists) in management of H. pylori infection may hopefully trigger an era to remedy current crisis in clarithromycin resistance, a later gastric cancer can be practically preventable.
