Consumers are increasingly quality orientated and an understanding of the factors that influence product quality is a prerequisite to the development of programs to produce quality pork to meet market requirements. Pork quality is comprised of many components and is multi-factorial in nature. This review focuses on genetic and environmental influences on muscle color, water holding capacity, and palatability attributes. The impact of genetic factors such as breed variation and the influence of major genes (the Halothane and Rendement Napole genes), as well as relationships between carcass leanness and quality, are considered. In addition, the effect of nutrition, including vitamins and minerals, feeding level, and dietary energy:protein ratio, on pork quality is reviewed. Finally, the impact of diet on fat composition and quality is summarized.

Measurements across single grain boundaries in YBCO thin films and bulk bicrystals have been used to demonstrate the influence of grain boundary structure on the critical current carried across the grain boundary. In particular, we show that one role of grain boundary structure is to change the degree of pinning along the boundary, thereby influencing the critical current. This effect can be used to explain the large difference in critical current density across grain boundaries in thin films compared to that for bulk bicrystal. These differences illustrate the distinction between the intrinsic mechanism of coupling across the grain boundary that determines the maximum possible critical current across a boundary and the measured critical current which is limited by dissipation due to the motion of vortices.

The word \"permaculture\" is a contraction of \"permanent agriculture\" or \"permanent culture\". Permaculture principles are designed to support (or ensure) the survival of humanity, the earth and all on it, and, to improve our standard of living, Permaculture can be defined as : a design system for creating sustainable human environments that can be (relatively) easily constructed and maintained. The principles of permaculture designs are relative location every element (such as house , rice paddy, road, esc) is placed in relation to each other such that each assists the other : each element performs multiple functions ; each function is supported by many elements : energy efficient planning ; using biological resources rather than fossil fuels : energy cycling on site (both fuel and human energy) : Using and accelerating natural plant succession to establish favourable sites and soils ; poly-culture and diversity of beneficial species for a productive, interactive system ; use of edge and natural patterns for best effect. These principles can be used for any permaculture design, in any climate, and at any scale. There has been very little scientific examination of Permaculture, and as such, it must be viewed as a design philosophy.viewed as a design philosophy.

Objectives : We already reported the effectiveness of this treatment method(electroacupuncture at oculomotor muscles) at the adult and young idiopathic paralytic strabismus patients and Miller-Fisher syndrome. Then I explored the possibility for improvement of the traumatic injury paralytic strabismus case. Methods : I treated the case by using the electroacupuncture at both paralytic lateral rectus muscle lesions. The case was treated almost daily and every treatment was enforced 10 minutes. I use the PG-306 electra-acupuncture products(Suzuki Iryoki Co. Japan) and apply the low consequence wave of 1-8Hz. Results : We gained good results from the case and not observed any sides effect or compliant. So I hope to apply this treatment for traumatic and post-operative nerve injury cases and am sure to make the treatment protocol for them in the future.

In this paper, we present a low-voltage low-dropout voltage regulator (LDO) for a system-on-chip (SoC) application which, exploiting the multiplication of the Miller effect through the use of a current amplifier, is frequency compensated up to 1-nF capacitive load. The topology and the strategy adopted to design the LDO and the related compensation frequency network are described in detail. The LDO works with a supply voltage as low as 1.2 V and provides a maximum load current of 50 mA with a drop-out voltage of 200 mV: the total integrated compensation capacitance is about 40 pF. Measurement results as well as comparison with other SoC LDOs demonstrate the advantage of the proposed topology.

In this study , we have investigated leaching characteristics of heavy metals and alkalinity centering around steel mill slags by several extraction methods, for the purpose of risk assessment that exert influence on environment and offer of the foundation data of reuse by slags. Korean standard method, U.S.EPA Extraction Procedure, alkalinity extraction test and 9 step sequential fractionation experiment by Miller et al. were carried out for investigating teachability of steel mill slags. As a result of this experiment, heavy metals were little detected and it was considered that alkalinity does not exert a bad effect around environment in slabs with large particle size. By the result of 9 step fractionation experiment, heavy metal contents in slags were not plentiful, in addition, even comparatively plentiful contended heavy metals, for the most part, were likely to detained or bonded in silica matrix. Therefore, in case of slags with large particle size, it seems that teachability of heavy metals were next to impossible that is existed as a safety condition.

Purpose: The purpose of this study was to compare clinical effect of the Langer & Langer technique, the modified Langer & Langer technique and Bruno technique. Material and Methods: 30 patients who have gingiva recession(Miller class I or class II) were carried root coverage. Langer & Langer technique(14 patients/32 tooth), modified Langer & Langer technique(5 patients/10 tooth) and Bruno technique(11 patients/18 tooth) was carried. At baseline and average 3 months after operation, it was estimated clinical index(Pocket depth, gingiva recession, clinical attachment level, keratinized gingiva, scar tissue, root coverage rate) by Williams style probe. Result: Root coverage rate is indicated Langer & Langer technique(8S%), Modified Langer & Langer technique(86%) and Bruno technique(90%). Conclusion: All three of the procedures were effective in gingival recession and improved clinical parameters.

Miller feedback compensation is introduced in a low dropout regulator (LDO) in order to obtain a capacitor-free regulator and improve the fast transient response. The conventional LDO has a limited bandwidth because of the large-size output capacitor and parasitic gate capacitance in the power MOSFET. In order to obtain a stable frequency response without the output capacitor, LDO is designed with resistor-capacitor (R-C) compensation and this is achieved with a connection between the gain-stage and the power MOS. An R-C compensator is suggested to provide a pole and zero to improve the stability. The proposed LDO is designed with the 0.35 μm CMOS process. Simulation testing shows that the phase margin in the Bode plot indicates a stable response, which is over 100^o. In the load regulation, the transient time is within 55 μs when the load current changes from 0.1 to 1 mA.

A two-dimensional direct numerical simulation was performed to investigate the flame structure of CH$_4$$N_2$-air counterflow nonpremixed flame interacting with a single vortex. The detailed transport properties and a modified 16-step augmented reduced mechanism based on Miller and Bowman's detailed chemistry were adopted in this simulation. The characteristic vortex and chemical time scales were introduced to quantify and investigate the extinction phenomenon during a flame-vortex interaction. The results showed that fuel- and air-side vortex cause an unsteady extinction. In this case, the flame interacting with a vortex was extinguished at much larger scalar dissipation rate than steady flame. It was also found that the air-side vortex extinguished a flame more rapidly than the fuel-side vortex. Furthermore, it was noted that the degree of unsteady effect experienced by a flame can be investigated by comparing the above two characteristic time scales, and this analysis could give an appropriate reason for the results of the previously reported experiment.
