The Effect of Warm Compress on Reducing Dymenorrhic Pain: Literature Review

Background: Dysmenorrhea is uterine discomfort caused by uterine contractions before and after menstruation. Dysmenorrhea is caused by excessive secretion of prostaglandins, which causes the uterus to enlarge and cause pain. Dysmenorrhea is characterized by abdominal pain, low back pain, nausea and vomiting, fatigue, dizziness, and even fainting. Dysmenorrhea can be treated with medications or non-drugs. Medication carries the risk that it may be unpopular. Its use to treat menstrual problems carries significantly lower risks than non-drug treatments. One way to reduce menstrual cramps is to apply heat. Objective: To explore the effect of warm compress therapy in relieving dysmenorrhea pain through literature review and provide empirical basis. Methods: This study is based on a comprehensive national and international literature review conducted during 2023 using Google Scholar, Research Gate, Publish or Perish using the keywords heat compress, dysmenorrhea. Results: A total of 20 articles from 3 journals were screened and included. The inclusion criterion was the effect of hot compress in relieving dysmenorrhea. It was found that it dropped by about 1.27 after hot compress treatment. And the 20 papers examined showed a significant effect on reducing dysmenorrhea pain, p-value = value <0.05. Conclusion: Hot compress therapy has been shown to be an alternative treatment for menstrual pain relief and is a safe way to treat the pain women experience during menstrual cramps.

Effect of hot compression on the microstructure evolution of aluminium bronze alloy

This work aims to study the flow behaviour, phase transformation, and microstructure evolution of aluminium bronze (Cu–9Al–4Fe) alloy. The hot compression behaviour of aluminium bronze were studied using simulator isothermal hot compression tests investigated at strain rates of 0.01–10 s−1 and temperature of 500–800 °C. According to the construction of constitutive equation and three-dimensional hot processing maps, the activation energy was 275.64 kJ/mol. The precipitated fine κⅣ particles during hot compression inhibit grain growth; the coarse κⅡ particles promote dynamic recrystallization through the mechanism of particle-stimulated nucleation (PSN). The formation of deformation twins under the influence of the fine κⅣ particles and high-density annealing twins are formed by stacking fault energy (SFE). Phase transformation by hot compression of the material at 500–800 °C, where the structure consists of the α phase and (α + γ2) eutectoid structure to α + β phase, is important for the increase in the power dissipation factor. Adiabatic shear leads to wedge-shaped cracks at 500 °C and 600 °C, 10 s−1, which pass through the (α + γ2) eutectoid structure and α phase interface with coarse-phase particles. The discontinuous dynamic recrystallization (DDRX) mechanism is the dominant DRX mechanism for aluminium bronze, in which DDRX, characterized by grain boundary bulging, was activated. The strengthening mechanism of aluminium bronze includes dispersion strengthening, twin strengthening, and grain refining strengthening during hot deformation, which leads to the increased activation energy of aluminium bronze alloy.

Effect of hot compress of the abdomen with stir-frying with coarse salt and Fructus Evodiae on abdominal distension, gastrointestinal reactions and mental status of patients with nephrotic syndrome

Objective To explore the effect of hot compress of the abdomen with stir-frying with coarse salt and Fructus Evodiae on abdominal distension, gastrointestinal reactions and mental status of patients with nephrotic syndrome(NS). Methods A total of 120 patients with primary NS who were admitted to the hospital from October 2015 to February 2018 were selected. By the random number table method, they were divided into control group and observation group, 60 cases of each group. The control group was treated with prednisone, low molecular dextran and was given routine nursing intervention. On this basis, the observation group was given hot compress of the abdomen with stir-frying with coarse salt and Fructus Evodiae combined with psychological counseling intervention. The relief of abdominal distension, gastrointestinal symptoms, mental status and quality of life scores before and after intervention were compared between the two groups. Results The apparent relief efficiency of abdominal distension in the observation group was higher than that in the control group, and the difference was statistically significant (P 0.05). Scores of nausea and constipation in both groups were decreased after intervention, and the differences was statistically significant (P<0.05). The scores of the observation group were lower than those of the control group, and the difference was statistically significant (P<0.05). The HAMA and HAMD scores of both groups were decreased after intervention, and the differences were statistically significant (P<0.05). The scores of observation group were also lower than those of the control group, and the differences were statistically significant (P<0.05). SF-36 scores of both groups were increased after intervention, and the differences were statistically significant (P<0.05), and the score of observation group was higher than that of the control group, and the difference were statistically significant (P<0.05). Conclusion Hot compress of the abdomen with stir-frying with coarse salt and Fructus Evodiae combined with psychological counseling can effectively relieve abdominal distension and gastrointestinal reactions in patients with NS and regulate their psychology, which is conductive to improving quality of life of patients.

Dissolution Kinetics of Hot Compressed Oxide Glasses.

The chemical durability of oxide glasses is an important property for a wide range of applications and can in some cases be tuned through composition optimization. However, these possibilities are relatively limited because around 3/5 of the atoms in most oxide glasses are oxygens. An alternative approach involves post-treatment of the glass. In this work, we focus on the effect of hot compression on dissolution kinetics because it is known to improve, for example, elastic moduli and hardness, whereas its effect on chemical durability is poorly understood. Specifically, we study the bulk glass dissolution rate of phosphate, silicophosphate, borophosphate, borosilicate, and aluminoborosilicate glasses, which have been compressed at 0.5, 1.0, and 2.0 GPa at the glass transition temperature (Tg). We perform weight loss and supplementary modifier leaching measurements of bulk samples immersed in acid (pH 2) and neutral (pH 7) solutions. Compression generally improves the chemical durability as measured from weight loss, but the effect is highly composition- and pressure-dependent. As such, we show that the dissolution mechanisms depend on the topological changes induced by permanent densification, which in turn are a function of the changes in the number of nonbridging oxygens and the network cross-linking. We also demonstrate a direct relationship between the chemical durability and the number of chemical topological constraints per atom (nc) acting within the molecular network.

Effects of hot compression on carbide precipitation behavior of Ni—20Cr—18W—1Mo superalloy

The effect of hot compression on the grain boundary segregation and precipitation behavior of M6C carbide in the Ni–20Cr–18W–1Mo superalloy was investigated by thermomechanical simulator, scanning electronic microscope (SEM) and X-ray diffraction (XRD). Results indicate that the amount of M6C carbides obviously increases in the experimental alloy after hot compression. Composition analyses reveal that secondary M6C carbides at grain boundaries are highly enriched in tungsten. Meanwhile, the secondary carbide size of compressive samples is 3–5 μm in 10% deformation degree, while the carbide size of undeformed specimens is less than 1 μm under aging treatment at 900 and 1000 °C. According to the thermodynamic calculation results, the Gibbs free energy of γ-matrix and carbides decreases with increase of the compression temperature, and the W-rich M6C carbide is more stable than Cr-rich M23C6. Compared with the experimental results, it is found that compressive stress accelerates the W segregation rate in grain boundary region, and further rises the rapid growth of W-rich M6C as compared with the undeformed one.

Effect of Hot Compression on Mechanical Properties of Gray Iron

Gray iron was hot-compressed on a Gleeble 3500 machine. The effect of hot compression on mechanical properties of gray iron was studied. The result shows that gray iron with the sandwich structure of graphite and ferrite matrix is prepared after more than 45% reduction of hot compression. The mechanical properties of 80% hot-compressed gray iron are significantly enhanced: tensile strength from 117MPa to 249MPa, and total elongation from 0 to 5.2%. The tensile fracture surface presents ductility characters after more than 45% reduction of hot deformation. The increase of the strength and ductility of the hot-compressed gray iron is caused by delamination toughening.

Effect of hot compression and annealing on microstructure evolution of ZK60 magnesium alloys

Microstructural evolution of ZK60 magnesium alloys, during twin roll cast (TRC) and hot compression (HC) with a strain rate of 0.1 s−1 at 350 °C and subsequent annealing at temperatures of 250–400 °C for 102−5 × 105 s, has been observed by optical microscopy (OM), transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD). The distribution of average grain size and recrystallized grain size at different annealing conditions were calculated. Activation energy and recrystallized volume fractions during annealing were discussed using analysis of static recrystallization (SRX) kinetics. Based on examination of microstructure evolution during annealing, it was found that several SRX mechanisms were co-activated. Subgrains with high misorientation angles to surrounding grains were formed by dislocation rearrangement, and they seemed to evolve into newly recrystallized grains.
