Abstract:
Stress intensity factor of thermal fatigue crack was calculated within one cycle by using finite element method in consideration of the multi-linear kinematic hardening characteristic of a material. The affection of loading sequence to stress intensity factor was studied under circularly variational temperature by comparing to that in one cycle. The low temperature cycle can not affect the stress intensity factor of latter cycles with high temperature; but high temperature cycle can affect the stress intensity factor of latter cycles with low temperature, and make it be equal to that of the hi

AbstractOrienteering is an endurance sport that combines physical and cognitive activity, during which the athlete must complete a course with several points distributed over unknown terrain in the shortest possible time. A number of studies have investigated the body’s physiological adaptations to the stress caused during competition, but not the immunological changes. To that end, the present study evaluated the immunological, physiological and pathological responses in athletes performing high-intensity physical exercise during an orienteering race.

In untrained subjects, strenuous exercise provokes the appearance of oxidant stress markers in blood and muscle. On the other hand, trained muscle is resistant to oxidant stress unless exercise challenges the muscle glycogen supply. It is not known whether chronic high-intensity exercise alters the susceptibility of skeletal muscle to oxidant stress, whether there are gender-related differences in markers of oxidant stress, or whether elevating muscle glycogen stores by increasing dietary carbohydrate can minimize any exercise-related oxidant stress.

Abstract:
There are evidence that high-intensity acute exercise can promote oxidative stress. High-intensity intermittent exercise (HIIE) is a type of structured physical training characterised by repeated bouts of high-intensity exercise interspersed by recovery periods. As the impact of intermittency during acute HIIE has not been extensively studied, it is possible that the repeated intensive bouts within HIIE could induce oxidative stress levels. Plasma biomarkers, including lipid hydroperoxides and markers of DNA damage, have been increasingly applied within acute exercise physiology research to me

Abstract:
Very high cycle fatigue (VHCF) is generally considered as the domain of fatigue lifetime beyond 10 million (107) load cycles. Few examples of structural components which are subjected to 107-109 load cycles during their service life are engine parts, turbine disks, railway axles and load-carrying parts of automobiles. Therefore, the safe and reliable operation of these components depends on the knowledge of their fatigue strength and the prevalent damage/failure mechanisms. Moreover, the fatigue life of materials in the VHCF regime is controlled by the fatigue crack initiation and early growth

The continuous enhancement of reliability and durability requirements for many machinery components is significantly pushing the experimental research on the Very-High-Cycle Fatigue (VHCF) response of metallic materials. In order to significantly reduce testing time, ultrasonic testing machines are widely adopted when carrying out VHCF tests. In the VHCF literature, the critical Stress Intensity Factor (SIF) is estimated by applying analytical SIF formulations to the typical semi-circular surface crack geometry revealed by fracture surfaces at final failure.

Abstract The effect of rising and falling stress intensity factor (K) on the SCC growth rates of stainless steel and nickel alloys has been studied in high temperature water.

The majority of SCC problems develop adjacent to welds, which have a complex residual stress profile vs. wall thickness. This, coupled with the dependence of K on crack length, causes K to change as the crack grows, not per se with time (t). Th

Abstract The presence of hydrogen sulfide (H2S) in the oil and gas exploration, extraction, and production processes poses hydrogen embrittlement and sulfide stress cracking (SSC) concerns for high strength low alloy Oil Country Tubular Goods (OCTG) steels. This paper presents Critical Stress Intensity Factor (KISSC) data obtained from two heats of standard mill produced API(1) C110 (microalloyed AISI 4130 steel – UNS G41300) casing steels. Double cantilever beam (DCB) samples from this material were tested in NACE(2) A solution in various sour environments (3.5 %, 7.0 %, 14 %, 22.0 %, 50 %, a

Abstract:
Abstract All grades and conditions of stainless steel are susceptible to SCC in high temperature water, whether deaerated or aerated; high H2 or low; theoretical purity water, buffered or contaminated; lower temperature or higher; etc. However, the kinetics of SCC growth vary markedly with stress intensity, yield strength, corrosion potential, water purity, sensitization, Si concentration, grain boundary characteristics, irradiation, temperature, etc. Among these factors, the presence of elevated Si concentration is responsible for unusually high growth rates as well as insensitivity to change

ABSTRACT A thorough characterization of nickel-based UNS N09955 was performed in a simulated sour production wellbore environment for high-pressure, high-temperature (HPHT) subsea applications. The test environment chemistry was 1.14 mol% of carbon dioxide (CO2), 0.4-psia fugacity of hydrogen sulfide (H2S), 240,000 mg/L of chlorides, dissolved oxygen less than 10 ppb, and a pH of 4.2, at 400 °F (204 °C) temperature. Environmentally assisted cracking (EAC) susceptibility was evaluated by fracture toughness (FT) test using compact tension test specimens and rising displacement method. Fatigue cr

Abstract:
Abstract The intergranular stress corrosion cracking (IGSCC) behavior of cold-worked 316 stainless steels in hydrogenated high-temperature water (500 ppm B + 2 ppm Li + 30 cc/kg-H2O-STP DH2) were investigated using compact tension specimens that had been cold-worked in the T-S orientation. The crack growth rates were examined as a function of cold work, temperature and stress intensity. In addition, the influence of cold work on corrosion was investigated. The results of the CT test on T-S orientation specimens revealed that the crack branched off in two directions, thus deviating from the nor

Abstract:
Abstract Stress corrosion crack (SCC) growth rate tests were conducted on sensitized and non-sensitized stainless steels (Type 304, 304L) cold worked to levels between 18 and 28%. Compact tension specimens were actively loaded to a stress intensity factor of approximately 38 MPa√m and exposed to high temperature, high purity water at 360°C under constant load conditions. Specimens were also ring loaded to a K level of approximately 35 MPa√m and exposed to high temperature high purity water at 338°C. SCC was observed in every specimen test with the exception of the 304L specimen cold worked 18%

Abstract:
This report presents results of a preliminary evaluation of a mechanical property that has the potential to correlate with susceptibility to Stress-corrosion cracking (SCC). This mechanical property measures the evolution of the microplastic response of line pipe steels, which underlies high pH SCC, and is believed by many to be essential for near-neutral SCC. If such a property can be proven to reflect susceptibility to SCC, operators could better contain maintenance costs and specify steels for new pipelines that are inherently resistant to SCC.

Assay the effects of altered RB60 expression on thylakoid biogenesis and photosynthetic function in plants exposed to different light conditions. In addition, we also examined the gene structure and expression of RB60 orthologs in the non-vascular plant, Physcomitrella patens and cloned the poly(A)-binding protein orthologue (43 kDa RB47-like protein).

The article presents varieties and variants of relaxation techniques advisable to use after intense physical exertion. The concept of "relaxation" and understanding of its role in physical education to maintain health and harmonious development of youth are considered. Considering the fact that one of the main trends in sports remains the increase in the intensity of training and the need to improve the results of competitions, the problem of restoring the athlete's performance capacity after physical exertion is extremely relevant today.

Biological oxidations are almost exclusively metal ion-promoted reactions and in ths respect iron, being the most abundant, is the commonly involved. The effect of dietary iron levels on pork, turkey and chick muscle lipid peroxidation and various other related compounds were evaluated. Crossbred feeder pigs were fed to market weight on corn-soy rations containing either 62, 131 or 209 ppm iron. After slaughter, the muscles were dissected, cooked and stored at 4°C.
