THE EFFECT OF RESISTANCE AND ENDURANCE EXERCISE TRAINING ON MUSCLE PROTEOME EXPRESSION IN HUMAN SKELETAL MUSCLE
Hee Jeong Son,Chang Keun Kim,Hyo Jeong Kim
Biology of Sport , 2012,
Abstract: To investigate the effect of resistance and endurance training on muscle proteome expression, samples of vastus lateralis from 10 physically active young men were analysed by 2-dimensional electrophoresis (2-DE) and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). Differential patterns of protein expression were determined after 4 weeks of endurance or resistance exercise training. Following endurance exercise training, carbonic anhydrase III immunoglobulin heavy chain, myosin heavy chain 1, titin, chromosome 12, and fructose-1,6-bisphosphatase 2 were up-regulated while pyruvate kinase 3 isoform, ubiquitin carboxyl-terminal hydrolase, and phosphoglucomutase were down-regulated. After the 4 weeks of resistance exercise training, five proteins, apolipoprotein A-IV precursor, microtubule-actin cross linking factor 1, myosin light chain, growth hormone inducible transmembrane protein, and an unknown protein were up-regulated and pyruvate kinase 3 isoform, human albumin, and enolase 3 were down-regulated. We conclude that endurance and resistance exercise training differently alter the expression of individual muscle proteins, and that the response of muscle protein expression may be associated with specific myofibre adaptations to exercise training. Proteomic studies represent one of the developing techniques of metabolism which may substantially contribute to new insights into muscle and exercise physiology.
Effects of squeezing on quantum nonlocality of superpositions of coherent states
Chang-Woo Lee,Hyunseok Jeong
Physics , 2009, DOI: 10.1103/PhysRevA.80.052105
Abstract: We analyze effects of squeezing upon superpositions of coherent states (SCSs) and entangled coherent states (ECSs) for Bell-inequality tests. We find that external squeezing can always increase the degrees of Bell violations, if the squeezing direction is properly chosen, for the case of photon parity measurements. On the other hand, when photon on/off measurements are used, the squeezing operation can enhance the degree of Bell violations only for moderate values of amplitudes and squeezing. We point out that a significant improvement is required over currently available squeezed SCSs in order to directly demonstrate a Bell-inequality violation in a real experiment.

Effect of Two-Stage Fuel Injection Parameters on NOx Reduction Characteristics in a DI Diesel Engine

Energies , 2011, DOI: 10.3390/en4112049
Abstract: The aim of this study was to confirm the effects of two-stage combustion on the combustion and NO x reduction characteristics of a four cylinder direct injection diesel engine. In order to analyze the combustion and emission characteristics, various injection parameters, such as injection quantity, injection timing and injection pressure were used under constant engine speed and engine load. In addition, the experimental results of two-stage combustion are compared to the single injection when injection timing is 5° BTDC. The experimental results showed that NO x emissions were significantly reduced when applying two-stage combustion. In particular, an injection strategy when the first and second injections have a same quantity, the results showed the maximum reduction of NO x emissions in this experiment. The NO x emissions were also reduced when the timing of the first injection was advanced. However, NO x emissions indicated almost similar concentration regardless of first injection timings when the first injection timing was earlier than 50° BTDC. In the case of soot emissions were slightly increased compare to the single injection cases at tested conditions.

An immunohistochemical study of the pancreatic endocrine cells of the ddN mouse.

Folia Histochemica et Cytobiologica , 2010, DOI: 10.5603/4191
Abstract: The regional distribution and frequency of the pancreatic endocrine cells in the ddN mouse were studied using specific antisera against insulin, glucagon, somatostatin and human pancreatic polypeptide (hPP). In the pancreatic islets, most of insulin-immunoreactive (IR) cells were located in the central region, and glucagon-, somatostatin and hPP-IR cells were located in the peripheral region regardless of the lobe. In the splenic part, glucagon-IR cells were also located in the central regions, and more numerous somatostatin-IR cells were detected in the central regions as compared with the duo-denal part. hPP-IR cells were restricted to the peripheral regions in both lobes but more numerous cells were detected in the duodenal portion. In the exocrine parenchyma of the splenic lobe, only insulin- and glucagon-IR cells were detected but all four kinds of IR cells were observed in the duodenal portion. In addition, insulin and hPP-IR cells were also demonstrated in the pancreatic duct regions. In conclusion, some strain-dependent characteristic distributional patterns of pancreatic endocrine cells were found in the ddN mouse with somewhat different distributional patterns between the two pancreatic lobes.
Prediction Performance of Chemical Mechanisms for Numerical Simulation of Methane Jet MILD Combustion
Yu Jeong Kim,Chang Bo Oh,Osamu Fujita
Advances in Mechanical Engineering , 2013, DOI: 10.1155/2013/138729
Abstract: The prediction performance of five chemical mechanisms (3-STEP, WD4, SKELETAL, DRM-19, and GRI-2.11) was investigated to confirm their suitability for use in numerical simulations of methane combustion in moderate or intense low-oxygen dilution (MILD). A wall-confined jet geometry was introduced to simulate MILD combustion. The oxygen level in the coflowing air was adjusted by mixing the air with combustion products. Each chemical mechanism was analyzed with respect to the flame structure and main product, including CO and NO; the emission indices for CO were also discussed. The temperature distributions and heat-release rates predicted by the chemical mechanisms were similar when the flames were stably attached to the fuel jet exit. The temperature distributions and heat-release rates were dependent on the flame liftoff characteristics, as were the CO and NO emissions. The NO concentration predicted by GRI-2.11 was lower than those predicted using other chemical mechanisms, although DRM-19 predicted a relatively similar value. The emission indices for NO (EINO) and CO (EICO) predicted by each chemical mechanism decreased with increasing dilution rate. The predicted EICO had a negative value even at a small dilution rate, which implies that some of the CO supplied to the air stream is consumed during MILD combustion. 1. Introduction Common high-temperature facilities adopt a combustion process to transform the chemical energy of fossil fuels into thermal energy. A major portion of the energy used worldwide is still derived from the combustion of various fossil fuels. However, this combustion causes many environmental problems, including pollutant emission and greenhouse effect, and also inevitably depletes the limited energy resources. Recent problems with respect to the environment and energy supply and demand require innovative combustion technologies in order to reduce the pollutant emission and greenhouse effect by enhancing the thermal efficiency of high-temperature facilities. Moderate or intense low-oxygen dilution (MILD) combustion [1], also known as flameless oxidation (FLOX) [2] or high-temperature air combustion (HiTAC) [3–5], is a promising combustion technology that results in high thermal efficiency and reduced emission of pollutants, such as , CO, and soot, by using heat-regenerated, high-temperature, low-oxygen air from the product gases. Recently, numerous studies have focused on high-temperature air combustion and the development of a MILD combustor. Dally et al. [6, 7] evaluated turbulent and combustion models for the numerical

Noncommutative Torus from Fibonacci Chains via Foliation
Hyeong-Chai Jeong,Eunsang Kim,Chang-Yeong Lee
Physics , 2000, DOI: 10.1088/0305-4470/34/31/201
Abstract: We classify the Fibonacci chains (F-chains) by their index sequences and construct an approximately finite dimensional (AF) $C^*$-algebra on the space of F-chains as Connes did on the space of Penrose tiling. The K-theory on this AF-algebra suggests a connection between the noncommutative torus and the space of F-chains. A noncommutative torus, which can be regarded as the $C^*$-algebra of a foliation on the torus, is explicitly embedded into the AF-algebra on the space of F-chains. As a counterpart of that, we obtain a relation between the space of F-chains and the leaf space of Kronecker foliation on the torus using the cut-procedure of constructing F-chains.
