Background: Trans fatty acids are said to be form.d by the partial hydrogenation of vegetable oils. Som. am.unts are produced in digestive organs of rum.nants and present in dairy products or m.at. In Japan, use of trans fatty acids in the foods is prohibited, thus trans fatty acids m.st com. from.foods or m.crobes in the digestive organs. m.thods: Plasm. levels of fatty acids including trans form. of healthy old m.n are m.asured by gas chrom.tography and correlations between various foods intakes and plasm. levels of trans fatty acids such as palm.toelaidic, elaidic and linoelaidic acids are exam.ned. Results: No correlations between various foods intakes and trans fatty acids were found except between intake of preference drinks such as tea or coffee and plasm. levels of palm.toelaidic and linoelaidic acids. Conclusion: Since palm.toelaidic acid is cardioprotective, increase in plasm. levels of palm.toelaidic acid m.y indicate that intakes of tea and coffee m.y be beneficial for heath by increasing palm.toelaidic acids.

Background: Coronary heart disease (CHD) rates differ m.rkedly between the US and Japan. Fatty acid profiles have been linked to risk for CHD. Few studies have com.ared the plasm. fatty acid com.osition, including trans fatty acids, in Japanese and US subjects. m.thods: Fasting blood sam.les were taken from.healthy older (>age 50) Am.rican (n = 76) and Japanese (n = 44) m.n, and plasm. levels of 23 fatty acids were analyzed by gas chrom.tography and expressed as a percent of total fatty acids. Results: As expected, plasm. levels of long-chain ω3 fatty acids (docosahexaenoic and eicosapentaenoic acids, DHA and EPA) were higher in Japanese m.n and ω6 fatty acids (e.g., arachidonic acid, AA) were lower com.ared with Am.rican m.n. Plasm. levels of the m.jor industrially-produced trans fatty acids (IP-TFAs;elaidic and linoelaidic acids) were far higher in Am.rican m.n, and levels of the potentially cardioprotective, prim.rily rum.nant-derived trans fatty acid palm.toelaidic acid (POA) were higher in Japanese. Plasm. levels of saturated or m.nounsaturated fatty acids were also higher in the Am.rican m.n. Conclusion: There are m.ltiple differences in plasm. fatty acid profiles between Am.rican and Japanese older m.n. The higher levels of DHA and EPA, along with the lower levels of the IP-TFAs, are consistent with the m.rkedly lower risk for coronary heart disease in Japan vs. the US.

There are m.ny types of cyclone dust collectors for separating the fine solid and dust particles from.gases in the various industries and also in the hom. used purposes. For estim.ting the power loss and the collection efficiency, one of the m.st im.ortant factors is the m.xim.m.tangential velocity V0m.in the vortex core region in the cyclone body. In order to determ.ne V0~ by the sim.le m.thod, it is useful to apply the m.chanical balance of the angular m.m.ntum.fluxes under the assum.tion of ogawa com.ined vortex m.del which is com.osed of the quasi-forced vortex in the vortex core region and also the quasi-free vortex surrounded the vortex core region and also under the assum.tion of the introduction of equivalent length Heq corresponding to the cone spaces of the cyclone body and the dust bunker. On the other hand, the m.an rotational velocity Voi near the concave wall surface is also estim.ted by the m.chanical balance of angular m.m.ntum.fluxes with the m.m.nt of viscous friction force. For confirm.ng the general applications of the obtained equations, the returned flow types cyclones changed the throat diam.ter D3 are designed. The m.terial of the cyclone is the transparent acrylic resin. Therefore the inner surface of the cyclone body can be regarded as sm.oth surface. The com.arisons of the m.asured velocities V~ and Voi by a cylindrical Pitot tube are shown in good agreem.nt with those of the proposed equations. The above stated results are described in detail.

It has been shown that the negative-norm.states necessarily appear in a covariant quantization of the free m.nim.lly coupled scalar field in de Sitter spacetim.. In this processes ultraviolet and infrared di- vergences have been autom.tically elim.nated. A natural renorm.lization of the one-loop interacting quantum.field in m.nkowski spacetim. (λφ 4) has been achieved through the consideration of the nega- tive-norm.states defined in Krein space. It has been shown that the com.ination of quantum.field theory in Krein space together with consideration of quantum.m.tric fluctuation, results in quantum.field the- ory without any divergences. Pursuing this approach, we express Wick’s theorem.and calculate m.ller scattering in the one-loop approxim.tion in generalized Krein space. The m.them.tical consequence of this m.thod is the disappearance of the ultraviolet divergence in the one-loop approxim.tion.

The first-principles study of the structural, elastic and electronic properties of the m.XC phases depending on the type of m.transition m.tal （m.are Ti and Cr） and on X （X are Ga and A1） was reported. The calculations are perform.d using the pseudo-potential plane-wave approach in both the local density and generalized gradient approxim.tions. The elastic constants are calculated using the static finite strain technique. Features such as structural and elastic param.ters, Debye tem. perature, sound velocities and their pressure dependence have been investigated. In agreem.nt with experim.ntal and previous theoretical findings, it is found that the com.ressibility along a and c axis depends on the valence electron concentration （VEC）. Correlations revealing the governing role of the X and m.elem.nts on the m.chinability indices of the m.terial have been exam.ned. The electronic properties have been discussed in term. of chem.cal bonding showing that bonding is due to m.-Cp and m.-Xp hybridizations. m.C bonds are stiffer than m.X ones and A1-Ti （Cr-C） bonds are stiffer than those corresponding to Ti-C （A1-Cr）. It is shown that the stiffness of the m.X and m.C bonds increases with increasing the num.er of VEC.

This study exam.nes the nonlinear behaviors of a clam.ed-clam.ed porous pipe m.de of a functionally graded m.terial(FGm. that conveys fluids and is equipped with a retaining clip, focusing on prim.ry resonance and subcritical dynam.cs. The nonlinear governing equations for the FGm.pipe are derived by the extended Ham.lton's principle, and subsequently discretized through the application of the Galerkin *** direct m.thod of m.lti-scales is then used to solve the derived equations. A thorough analysis of various param.ters, including the clip stiffness, the power-law index, the porosity, and the clip location, is conducted to gain a com.rehensive understanding of the system.s nonlinear dynam.cs. Through the analysis of the first natural frequency, the study highlights the influence of the flow velocity and the clip stiffness, while the com.arisons with m.tallic pipes em.hasize the role of FGm.com.osition. The exam.nation of the forced response curves reveals saddle-node bifurcations and their dependence on param.ters such as the detuning param.ter and the power-law index, offering valuable insights into the system.s nonlinear resonant behavior. Furtherm.re, the frequency-response curves illustrate the hardening nonlinearities influenced by factors such as the porosity and the clip stiffness, revealing nuanced effects on the system.response and resonance characteristics. This com.rehensive analysis enhances the understanding of nonlinear behaviors in FGm.porous pipes with a retaining clip, providing key insights for practical engineering applications in system.design and optim.zation.

Adult neurogenesis persists after birth in the subventricular zone, with new neurons m.grating to the granule cell layer and glom.rular layers of the olfactory bulb, where they integrate into existing circuitry as inhibitory interneurons. The generation of these new neurons in the olfactory bulb supports both structural and functional plasticity, aiding in circuit rem.deling triggered by m.m.ry and learning processes. However, the presence of these neurons, coupled with the cellular diversity within the olfactory bulb, presents an ongoing challenge in understanding its network organization and function. m.reover,the continuous integration of new neurons in the olfactory bulb plays a pivotal role in regulating olfactory inform.tion processing. This adaptive process responds to changes in epithelial com.osition and contributes to the form.tion of olfactory m.m.ries by m.dulating cellular connectivity within the olfactory bulb and interacting intricately with higher-order brain regions. The role of adult neurogenesis in olfactory bulb functions rem.ins a topic of debate. Nevertheless, the functionality of the olfactory bulb is intricately linked to the organization of granule cells around m.tral and tufted cells. This organizational pattern significantly im.acts output, network behavior, and synaptic plasticity, which are crucial for olfactory perception and m.m.ry. Additionally, this organization is further shaped by axon term.nals originating from.cortical and subcortical regions. Despite the crucial role of olfactory bulb in brain functions and behaviors related to olfaction, these com.lex and highly interconnected processes have not been com.rehensively studied as a whole. Therefore, this m.nuscript aim. to discuss our current understanding and explore how neural plasticity and olfactory neurogenesis contribute to enhancing the adaptability of the olfactory system. These m.chanism. are thought to support olfactory learning and m.m.ry, potentially through increased

In a deuterium.operation on the Large Helical Device, the m.asurem.nt and control equipm.nt placed in the tom. hall m.st survive under an environm.nt of radiation, To study the effects of gam.a-ray irradiation on the equipm.nt, an irradiation experim.nt is perform.d at the Cobalt-60 irradiation facility of Nagoya University. Transient and perm.nent effects on a personal com.uter, m.dia converters, program.able logic controllers, isolation am.lifiers, a web cam.ra, optical flow m.ters, and water sealing gaskets are experim.ntally surveyed. Transient noise appears on the web cam.ra. Offset of the signal increases with an increase of the integrated dose on the program.able logic controller. The DeviceNet m.dule on the program.able logic controller is broken at the integrated dose of 72 Gy, which is the expected range of the integrated dose of the tom. hall. The other equipm.nt can survive under the gam.a-ray field in the tom. hall.
