Abstract:

Recently, technologies for medical inspection have been increasing rapidly. In biomedical industry, a demand of Micro Total Analysis System (μ-TAS) has been growing which used in automatically inspection for chemical analysis. The μ-TAS have micro passageway which is constructed by many fine micro holes. Final polishing by skilled workers are carried out after drilling to obtain smooth surface of holes. Because new manufacturing technique is required instead of skilled workers, it increases productivity and cost performance of the μ-TAS. Drilling technique with low temperature environment around cutting edge is required to prevent heat crack or adhesion on holes surface, because acrylic resin heats sensitive material. In this study, ultrasonically assisted micro drilling technique is proposed to increase productivity of μ-TAS and quality of micro holes. Ultrasonically assisted machining has effective technique to improve machinability, e.g. reduce cutting force, increase chip removability and machined surface quality. This paper describes the cutting characteristics of ultrasonically assisted micro-drilling for acrylic resin to employ the μ-TAS manufacturing to solve above problems.

Abstract:

Abstract. Particle concentration measurements with underwing probes on aircraft are impacted by air compression upstream of the instrument body as a function of flight velocity. In particular, for fast-flying aircraft the necessity arises to account for compression of the air sample volume. Hence, a correction procedure is needed to invert measured particle number concentrations to ambient conditions that is commonly applicable to different instruments to gain comparable results. In the compression region where the detection of particles occurs (i.e. under factual measurement conditions), pressure and temperature of the air sample are increased compared to ambient (undisturbed) conditions in certain distance away from the aircraft. Conventional procedures for scaling the measured number densities to ambient conditions presume that the air volume probed per time interval is determined by the aircraft speed (true air speed, TAS). However, particle imaging instruments equipped with pitot tubes measuring the probe air speed (PAS) of each underwing probe reveal PAS values systematically below those of the TAS. We conclude that the deviation between PAS and TAS is mainly caused by the compression of the probed air sample. From measurements during two missions in 2014 with the German Gulfstream G-550 (HALO – High Altitude LOng range) research aircraft we develop a procedure to correct the measured particle concentration to ambient conditions using a thermodynamic approach. With the provided equation, the corresponding concentration correction factor ξ is applicable to the high-frequency measurements of the underwing probes, each of which is equipped with its own air speed sensor (e.g. a pitot tube). ξ values of 1 to 0.85 are calculated for air speeds (i.e. TAS) between 60 and 250 m s−1. For different instruments at individual wing position the calculated ξ values exhibit strong consistency, which allows for a parameterisation of ξ as a function of TAS for the current HALO underwing probe configuration. The ability of cloud particles to adopt changes of air speed between ambient and measurement conditions depends on the cloud particles' inertia as a function of particle size (diameter Dp). The suggested inertia correction factor μ (Dp) for liquid cloud drops ranges between 1 (for Dp < 70 µm) and 0.8 (for 100 µm < Dp < 225 µm) but it needs to be applied carefully with respect to the particles' phase and nature. The correction of measured concentration by both factors, ξ and μ (Dp), yields higher ambient particle concentration by about 10–25 % compared to conventional procedures – an improvement which can be considered as significant for many research applications. The calculated ξ values are specifically related to the considered HALO underwing probe arrangement and may differ for other aircraft. Moreover, suggested corrections may not cover all impacts originating from high flight velocities and from interferences between the instruments and e.g. the aircraft wings and/or fuselage. Consequently, it is important that PAS (as a function of TAS) is individually measured by each probe deployed underneath the wings of a fast-flying aircraft.

Abstract:

Interests on the fabrication of microfluidic devices have increased in the fields of micro total analysis system (μ-TAS) and MEMS (Microelectromechanical systems) due to their chemical inertness and high thermal stability. The thermal characterization of the SiCN preceramic polymer, polyvinylsilazane, showed that the cured polymer has ceramic properties at heat treatment temperature of 600 oC or above. In the characterization of the mechanical properties, the characteristic values of the elastic modulus and hardness notably increased for the heat-treated SiCN. The present study describes the preparation of nano-sized patterns and microfluidic channels using a soft lithographic technique. The study shows that the fabrication of microchannels using the cured inorganic polymers holds tremendous potential in the field of microfluidics, where materials with high optical transparency, thermal stability and chemical inertness are in demand as niche between conventional microfluidics using glass and polymeric materials.

Abstract:

Demands of precision molds with complicated microstructures for digital devices such as DVD pick-up system, and medical devices such as μ-TAS and solar optics etc. are increasing. To enhance precision, the structured molds must be polished after grinding or cutting in order to improve the surface roughness. In this paper, a two-dimensional low frequency vibration (LFV) polishing actuator using PZT is proposed and developed. The LFV consists of four mechanical amplitude magnified actuators, a multilayer stacked piezoelectric actuator (PZT) incorporated with mechanical transformer, and a center piece. In the polishing experiments, HIPM workpieces were polished with WA slurry by the rotation & revolution type polishing method (RRP). The surface roughness of the work pieces and material removal amount (polished amount) was also evaluated. From the experimental results, it was found that the application of low frequency vibration is useful for realizing higher precision in the polishing of micro structured molds.

Abstract:

An electrostatically driven multi-electrode peristaltic micropump has been developed for pumping microfluid through μ-TAS. Peristaltic-type micropumps have been reported to address many of the problems of micropumps in general and electrostatic actuation in particular. Peristaltic motion can eliminate the need for valves and for proper valve timing or for a nozzle/diffuser in designing flow control, as well as contribute to reduce the dead volume which can be a critical problem for micropump to achieve higher back pressures. In this paper, we present an electrostatically driven bidirectional peristaltic micropump that was designed, fabricated, and characterized. It was fabricated on a silicon substrate with a polyimide membrane. It was consisted of single large chamber, PI membrane operated with 4 electrodes, and 4 phase sequencing actuation. The displacement of the meniscus in the capillary tube is observed and recorded by using a video camera. The micropump was operated from 115V to 135V. The maximum moving speed of the meniscus was approximately 24 mm/min at 2.2 kHz at 115V. This pump will be applied to various microfluidic fields.

Abstract:

Demands of precision molds with complicated microstructures for digital devices such as DVD pick-up system, medical devices such as μ-TAS and solar optics etc. are increasing [1 - 5]. The structured molds must be polished after grinding or cutting in order to improve the surface roughness. In this paper, a two dimensional low frequency vibration (2DLFV) polishing actuator using PZT is proposed and developed. The 2DLFV consists of 4 mechanical amplitude magnified actuators (MechaTrans), a multilayer stacked piezoelectric actuator (PZT) incorporated with mechanical transformer, and a center piece. Mechanical transformer is a kind of flexure hinges structured that magnifies the stroke of the multilayer stacked piezoelectric actuator around 7 times to 120 μm. With this actuation, the tool vibrates in a circle trajectory to achieve polishing effect. In the polishing experiments, tungsten carbide molds (workpieces) are polished with diamond slurry. The surface roughness of the work pieces and polishing efficiency are evaluated. From the experimental results, it was found that low frequency vibration especially 2DLFV is a useful polishing system for micro structured mold.

Abstract:

Research and development of micro-fluidic systems, such as μ-TAS and micro reactor system, has recently become active in the fields of chemical engineering and biotechnology. Micro mixing devices are an essential element in the realization of micro-fluidic systems. Therefore, in this research, a micro rotary reactor has been developed as a micro mixing device incorporated into micro-fluidic systems. The micro rotary reactor can form spiral laminar flow interfaces of two liquids through the rotation of a rotor. The spiral laminar flow interfaces increases the length and surface area of the reaction area between two liquids. But the previous prototype micro rotary reactor was only able to form spiral laminar flow interfaces under certain conditions. Therefore, the micro rotary reactor has been improved to form stable spiral laminar flow interfaces under a greater number of conditions. The full length and diameter of the improved micro rotary reactor are 60 mm and 15 mm, respectively. Experiments have shown that the improved micro rotary reactor can form spiral laminar flow interfaces under more varied conditions. This paper details the structure and the characteristics of the improved micro rotary reactor, as well as the experiments on its ability to form spiral laminar flow interfaces.

Abstract:

Precision polishing of micro structured mold has been highly demanded due to the increasing demand for optics manufacturing such as solar optics and DVD pick-up system, and medical devices like μ-TAS [1-5]. These micro structured molds usually have complicated structure and need to be polished after grinding or cutting. In this paper, a three-axis low frequency vibration (3DLFV) polishing actuator is proposed. The actuator consists of 3 multilayers-stacked piezoelectric actuators (PZT) incorporated with mechanical amplitude magnified mechanism. The mechanical amplitude magnified mechanism utilizes mechanical structures which is also called mechanical transformer, which is capable to elongate the stroke of the piezoelectric actuator to almost 13 times to 225 m. By driving the PZT in sine wave with particular phase different, dual direction trajectory such as circle can be achieved, and is proved to be effective in precision mold polishing [8]. With the 3DLFV actuations, polishing tool with polyurethane is actuated to stir the diamond slurry to achieve polishing effects. In polishing experiments, nickel-plating metal used as work pieces are polished with diamond slurry and the polished depths are measured. As a result, three-axis low frequency vibration (3DLFV) is proposed and developed. Its capability in polishing precise mold is studied and confirmed to be efficient. In order to improve the work piece surface, a dwell time control method can be applied with the 3DLFV.

Abstract:

The purpose of this study is to investigate the complex vortex flow patterns within a novel active micro-rotor mixer under various Reynolds numbers and rotating speeds by employing of CFD technique. The concept of present micro-rotor mixer is inspired from the Wankel-type combustor which is widely used in the power machines. The configuration of present micro-mixer is consisted of a rotor with shape of triangle column, a blending chamber and individual inlet and outlet ports. The blending chamber is served as the mixing chamber since the separated three sub-regions will change their volumes as the rotor undergoing the rotating motion with a fixed eccentricity. The dynamic flow patterns and mixing process of two species within the mixing chamber were simulated and visualized with streak lines. The governing equations are unsteady, two-dimensional incompressible Navier-Stokes equation and the two working fluids are pure water and alcohol. The concentration equation for species is also solved to reveal the mass transfer process in various sub-regions then being calculated on the outlet port to evaluate the mixing efficiency. The dynamic mesh technique was applied to re-distribute the computational meshes when the rotor finished a complete rotation cycle. Inspection on the flow developing stages within the mixing chamber over one complete cycle, it seems that multi-vortex flow field was generated due to the interaction of the shear force from the rotor, viscous force and inertial force of working fluids. The Coanda flow appeared in some conditions. When the Reynolds number is below of 10, the rotating speed of rotor has less influence on the mixing efficiency. An obvious enhancement in the mixing efficiency can be found in cases of the rotating speed of rotor changed from 30 rpm to 150 rpm when the Reynolds number in range of 25 to 100. Generally, the maximum mixing efficiency of 85% can be achieved for 1<Re<100 which demonstrated that present design was effective for μ-TAS.

Abstract:

Measuring fluid pressure in microchannels is difficult and constitutes a challenge to even the most experienced of experimentalists. Currently, to the best of the authors’ knowledge, no optimal solution are being used for the design of pressure taps, nor guidelines concerning their shape and its relation with the accuracy of the readings. In an attempt to address this issue, a parametric study was devised to evaluate the performance of different pressure tap designs, 18 in total. These were obtained by combining three shape parameters: sub-channel width (w) and sub-channel–tap radius (R) or angle (α), while having the sub-channel length kept constant. For each configuration, pressure drop measurements were carried out along several lengths of a straight microfluidic rectangular channel and later compared to an analytical solution. The microchannels were fabricated out of PDMS using standard soft-lithography techniques, pressure drop was measured with differential pressure sensors, the test fluid was DI water and the flow conditions varied from creeping flow up to R e c ∼100. Pressure taps, having smooth contours (characterised by the radius R) and a sub-channel width (w) of 108 μ m , performed the best with results from that of radius R = 50 μ m only falling short of the theory by a mere ∼ 5 % .

Abstract In this study, the relationships between friction and viscoelastic properties such as loss tangent tan δ and storage modulusE′ were examined. Wet skid resistance was measured using the British Pendulum Tester. The rubber specimens were rubbed againstfive silicone carbide cloths of differing abrasive grain sizes. The viscoelastic properties of the rubber specimens were measured with a viscoelasticspectrometer. From the data on wet skid resistance and viscoelastic properties, it is found that the coefficient of friction μ varies as follows: μ = a + b · tan δ/E′ where a and b are constants. Tan δ/E′ was related to the hysteresis term of friction, and the μ-frequency curves were compared with the tan δ/E′ –frequency curves.

Abstract:

This article presents a test bench with variable temperature control of the individual cells connected in parallel. This allows to reconstruct arising temperature gradients in a battery module and to investigate their effects on the current distribution. The influence of additional contact resistances induced by the test bench is determined and minimized. The contact resistances are reduced from R Tab + = 81.18 μ Ω to R Tab + = 55.15 μ Ω at the positive respectively from R Tab − = 35.59 μ Ω to R Tab − = 28.2 μ Ω at the negative tab by mechanical and chemical treating. An increase of the contact resistance at the positive tab is prevented by air seal of the contact. The resistance of the load cable must not be arbitrarily small, as the cable is used as a shunt for current measurement. In order to investigate their impacts, measurements with two parallel-connected cells and different load cables with a resistance of R Cab + = 0.3 m Ω , R Cab + = 1.6 m Ω and R Cab + = 4.35 m Ω are conducted. A shift to lower current differences with decreasing cable resistance but qualitatively the same dynamic of the current distribution is found. An extended dual polarization model is introduced, considering the current distribution within the cells as well as the additional resistances induced by the test bench. The model shows a high correspondence to measurements with two parallel-connected cells, with a Root Mean Square Deviation (RMSD) of ξ RMSD = 0.083 A.

We analyze the electric dipole moment and the Higgs mass constraints on the supersymmetric model which offers dynamical solutions to the μ and strong CP problems. The trilinear coupling phases, and tan β-|μ| are strongly correlated, particularly in the low-tan β regime. Certain values of the phases of the trilinear couplings are forbidden, whereas the CP violating phase from the chargino sector is imprisoned to lie near a CP conserving point, by the Higgs mass and electric dipole moment constraints.

Full text

Abstract:

Finite-element analyses for elastoplastic cone indentations were conducted in which the effect of linear strain hardening on indentation behavior was intensively examined in relation to the influences of the frictional coefficient (μ) at the indenter/material contact interface and of the inclined face angle (β) of the cone indenter. A novel procedure of “graphical superposition” was proposed to determine the representative yield stress YR. It was confirmed that the concept of YR applied to elastic-perfectlyplastic solids is sufficient enough for describing the indentation behavior of strainhardening elastoplastic solids. The representative plastic strain of εR (plastic) ≈ 0.22 tan β, at which YR is prescribed, is applicable to the strain-hardening elastoplastic solids, affording a quantitative relationship of YR = Y + ε;R (plastic) × EP in terms of the strain-hardening modulus EP. The true hardness H as a measure for plasticity is estimated from the Meyer hardness HM and then successfully related to the yield stress Y as H = C(β,μ) × Y for elastic-perfectly-plastic solids and as H = C(β,μ) × YR for strain-hardening solids, by the use of a β- and μ-dependent constraint factor C(β,μ) ranging from 2.6 to 3.2.

Abstract:

Abstract Sirolimus (Rapamycin, Rap) is an immunosuppressant structurally similar to tacrolimus (Tac), however, Rap inhibits T cell function via FKBP12/mTOR and may also inhibit dendritic cell function. Rap is synergistic with Tac and has no overlapping toxicity, allowing their use in combination. We have shown that Rap, Tac and low-dose methotrexate (Mtx) is effective GVHD prophylaxis after unrelated donor (URD) transplantation and the combination of Rap and Tac alone is effective in matched, related donor (MRD) transplantation. Since Mtx is associated with transplant-related toxicity and delayed engraftment, we hypothesized that Rap and Tac, without Mtx, would provide effective GVHD prophylaxis in URD transplantation while minimizing transplant-related morbidity and mortality. Methods: 28 subjects underwent peripheral blood stem cell transplantation (PBSCT) from 6/6 HLA-matched unrelated donors after Cy/TBI conditioning. GVHD prophylaxis consisted of Rap (target serum level 3–12 ng/ml) and Tac (target serum level 5–10 ng/ml). Filgrastim (5 μ g/kg) was administered from day+12 until engraftment, if needed. Results: The median age of subjects was 43.5 years (range 22–54). Diagnoses were AML(11), CML(6), NHL(4), MDS(3), ALL(2), MPD(1) and HD(1). The median times to neutrophil engraftment (>500/μ L) and platelet engraftment (>20,000/μ L and >100,000/μ L) were 13.5 (range 11–14), 12 (range 9–25), and 17 (range 12–101) days, respectively. All 28 patients survived to first hospital discharge, at a median of 19 days from day 0 (range 14–55). Gr. II acute GVHD occurred in 4 patients (14.3%) and Gr. IV acute GVHD occurred in 1 patient (3.5%), for an overall rate of Gr. II–IV acute GVHD of 17.9%. GVHD resolved with corticosteroids in all but 1 case. Transplant-related morbidity was low, without any cases of idiopathic pneumonia syndrome/diffuse alveolar hemorrhage. Two subjects developed VOD and one subject developed thrombotic microangiopathy. Reactivation of HHV-6 with limbic encephalitis was noted in 2 patients. Nine of 24 evaluable patients developed chronic GVHD (7 extensive, 2 limited). Five patients relapsed, one of whom achieved a complete remission after immunosuppression withdrawal and DLI. Causes of death include relapse(2), VOD(1), and relapse with VOD and hepatic GVHD(1). The median follow-up is 197 days (range 80–557). Treatment-related mortality at 100 days is 3.5%. Relapse-free and overall survival at day 100 are both 92.7%, and at 1 year are 75.4 and 83.6%, respectively. Conclusions: Rap and Tac without Mtx is effective for GVHD prophylaxis after matched URD PBSCT, leading to acute GVHD in 17.9% of treated patients, which is similar to our experience using Rap and Tac in MRD transplantation. Furthermore, the omission of Mtx is associated with minimal transplant-related morbidity and mortality. This combination is worthy of broader study in unrelated donor transplantation.

Abstract:

I argue that the observed flavor structures of leptons and quarks might imply the existence of certain flavor symmetries. The latter should be a good starting point to build realistic models towards deeper understanding of the fermion mass spectra and flavor mixing patterns. The μ-τ permutation symmetry serves for such an example to interpret the almost maximal atmospheric neutrino mixing angle (θ23 ~ 45°) and the strongly suppressed CHOOZ neutrino mixing angle (θ13 < 10°). In this talk I like to highlight a new kind of flavor symmetry, the Friedberg–Lee symmetry, for the effective Majorana neutrino mass operator. Luo and I have shown that this symmetry can be broken in an oblique way, such that the lightest neutrino remains massless but an experimentally-favored neutrino mixing pattern is achievable. We get a novel prediction for θ13 in the CP-conserving case: sin θ13 = tan θ12|(1 - tan θ23)/(1 + tan θ23)|. Our scenario can simply be generalized to accommodate CP violation and be combined with the seesaw mechanism. Finally I stress the importance of probing possible effects of μ-τ symmetry breaking either in terrestrial neutrino oscillation experiments or with ultrahigh-energy cosmic neutrino telescopes.

AbstractWe offer a proof of the following non-conventional ergodic theorem: If Ti:ℤr↷(X,Σ,μ) for i=1,2,…,d are commuting probability-preserving ℤr-actions, (IN)N≥1 is a Følner sequence of subsets of ℤr, (aN)N≥1 is a base-point sequence in ℤr and f1,f2,…,fd∈L∞(μ) then the non-conventional ergodic averages converge to some limit in L2(μ) that does not depend on the choice of (aN)N≥1 or (IN)N≥1. The leading case of this result, with r=1 and the standard sequence of averaging sets, was first proved by Tao, following earlier analyses of various more special cases and related results by Conze and Lesigne, Furstenberg and Weiss, Zhang, Host and Kra, Frantzikinakis and Kra and Ziegler. While Tao’s proof rests on a conversion to a finitary problem, we invoke only techniques from classical ergodic theory, so giving a new proof of his result.

Ta8(μ3-O)2(μ-O)8(μ-OEt)6(OEt)14 (1) was obtained by the controlled hydrolysis of tantalum ethoxide Ta(OEt)5 in the presence of ammonia. Compound 1 is considered as the intermediate building block in the sol–gel polymerization of Ta(OEt)5. Further hydrolysis of compound 1 yielded nanoparticles of Ta2O5, which were characterized by various techniques such as TGA-DTA-DSC, UV–vis DRS, XRD, SEM, TEM, particle size analyzer (DLS) and the Brunauer–Emmett–Teller (BET) method. The band gap of the particles was calculated by using the Tauc plot. The photocatalytic activity of Ta2O5 nanoparticles was tested by the degradation of the organic dye rhodamine B.

Abstract:

We consider the infrared quasi fixed point solutions of the renormalization group equations for the Yukawa couplings and soft supersymmetry breaking parameters in the MSSM in the large tan β regime. The existence of ir quasi fixed points together with the values of gauge couplings, third generation quarks, lepton and Z-boson masses allows one to predict masses of the Higgs bosons and SUSY particles as functions of the only free parameter, m1/2, or the gluino mass. The lightest Higgs boson mass for M SUSY ≈1 TeV is found to be mh=128.2-0.4-7.1± 5 GeV for μ>0 and mh= 120.6-0.1-3.8±5 GeV for μ<0.

Abstract:

we present a solution to the μ problem in an SO(10) supersymmetric grand unified (SUSY GUT) model with gauge mediated (GMSB) and D-term supersymmetry breaking. A Peccei-Quinn (PQ) symmetry is broken at the messenger scale and enables the generation of the μ term. The invisible axion (Goldstone boson of PQ symmetry breaking) is a cold dark matter candidate. At low energy, our model leads to a phenomenologically acceptable version of the minimal supersymmetric standard model (MSSM) with novel particle phenomenology. Either the gluino or the gravitino is the lightest supersymmetric particle (LSP). The phenomenological constraints on the model result in a Higgs with mass ~ 86 – 91 GeV and tan β ~ 9 – 14.

Abstract:

A traceability of frozen semen straws that certify the bloodline of a sire will improve the efficiency of cattle breeding. Semen of the sire can be generally identified by the colour of a straw and printing on a straw. However, it is difficult to identify individual frozen semen straws by the conventional method. To identify straws individually, each straw must be tagged with a unique ID that is able to be read quickly in the frozen state. We have established the identification method for individual frozen semen straws using radio frequency identification (RFID) and developed a traceability system that is able to record the distribution history of an individual semen straw from the production of frozen semen to artificial insemination (AI). We used a 2.5-mm diameter straw combined with an RFID tag, which consisted of a tiny RFID chip (μ-Chip: Hitachi Co. Ltd, 0.4 × 0.4 × 0.2 mm) and a thin aluminum antenna on the polyester sheet (54 × 1.5 × 0.05 mm). The μ-chip contains a unique ID (128 bit). It responds to the 2.45 GHz microwave frequency that is emitted from the RFID reader and transmits its ID to the RFID reader. The μ-Chip retains its function on a straw, which has been stored in the liquid nitrogen (–196°C). Artificial insemination of the frozen semen straw with the RFID tag could be performed using a conventional AI gun. The semen traceability system consisted of the database server and the client software. Information about semen straws is connected with their ID and stored on the database server. Producers and distributors of frozen semen can count the number of semen straws correctly by reading their ID one by one and can send information to the database server through the web by easy operation using the client software. Artificial insemination information can be instantly recorded by the handy terminal that is able to read both a bar-code on the ear tag of the cow and the RFID tag of the straw. The system has been used on fields at Gifu Prefecture in Japan for ∼3 months. Eight hundred thirty-one frozen semen straws with the RFID tag were produced from 3 bulls. After freezing of the straws, 17 straws were not identified with their ID. It was speculated that their μ-Chips were disconnected from the antenna during freezing. Six hundred ninety-four straws were distributed to the 7 AI centers. Five hundred thirty straws were used for AI by 15 inseminators to a total of 424 cows at the 101 farms. Although only one straw could not read its ID after AI, information of the remaining 529 straws were recorded on the database accurately. A strict traceability of frozen semen straws can be established using the individual identification of straws by RFID. Information stored in the database would be useful for the evaluation of sire and the reproductive management of cows. This work was supported by a grant from the Ministry of Agriculture, Forestry and Fisheries of Japan (MAFF).

Full text

Abstract:

It is demonstrated that transparent amorphous oxide semiconductors (TAOS) can be excellent thermoelectric (TE) materials, since their thermal conductivity (κ) through a randomly disordered structure is quite low, while their electrical conductivity and carrier mobility (μ) are high, compared to crystalline semiconductors through the first-principles calculations and the various measurements for the amorphous In−Zn−O (a-IZO) thin film. The calculated phonon dispersion in a-IZO shows non-linear phonon instability, which can prevent the transport of phonon. The a-IZO was estimated to have poor κ and high electrical conductivity compared to crystalline In2O3:Sn (c-ITO). These properties show that the TAOS can be an excellent thin-film transparent TE material. It is suggested that the TAOS can be employed to mitigate the heating problem in transparent display devices.

Abstract:

Iron absorption from three typical West African meals was measured in fourteen subjects using the extrinsic-tag technique with59Fe and55Fe. All meals consisted of maize as the staple food. Meals were prepared in Benin under realistic conditions from locally grown foods. Of the non-haem-Fe in the meals 39–73% did not exchange with the added inorganic radio-Fe tracer, depending on the degree of Fe contamination of meals. Non-haem-Fe absorption was low in each maize meal, but was even lower for those eaten with a vegetable sauce than for those eaten with a fish sauce. When haem-Fe absorption was included, 70.0–160μg Fe was absorbed. Expressed on an energy basis, the bioavailable nutrient density was 3.2–7.0 μ/100 kJ (13.4–29.5 μ/100 kcal). These findings suggest that total Fe available in the typical diets of West African countries does not meet the physiological requirements of large proportions of the population.

Abstract:

Estimates on drinking water consumption are necessary in risk assessments on microbial hazards in drinking water. Large differences in consumption habits between countries have been reported. In order to establish estimates for the Swedish population, water consumption data from a waterborne outbreak investigation (157 people), a small water consumption study (75 people) and a large study on health and environmental factors (10,957 people) were analysed. A lognormal distribution for the daily direct/cold water intake in litres with μ=−0.299 and σ=0.570 was fitted to the quantitative data, representing the general population. The average daily consumption of tap water as plain drinking water and as heated tap water, e.g. in coffee and tea, was 0.86±0.48 l and 0.94±0.69 l, respectively. Women consumed more cold tap water than did men, while men appeared to have a higher consumption of heated tap water. Cold tap water intake was highest in the oldest age group, (≥70 years). The consumption of bottled water was very low (mean 0.06 l/d) when compared to other countries.

Abstract:

We update the analysis of the precision electroweak tests in terms of four epsilon parameters, ε1,2,3,b, to obtain more accurate experimental values of them by taking into account the new LEP data released at the 28th ICHEP (Poland, 1996). We also compute ε1 and εb in the context of the no-scale SU (5)× U (1) supergravity model to obtain the updated constraints by imposing the correlated constraints in terms of the experimental ellipses in the ε1–εb plane and also by imposing the new conservative bound on the lightest chargino mass, [Formula: see text]. Upon imposing these new experimental results, we find that the situations in the no-scale model are much more favorable than those in the standard model, and if mt≳ 170 GeV, then the allowed regions at the 95% C.L. in the no-scale model are tan β≳ 4 and [Formula: see text] for μ>0 (μ< 0), which are in fact much more stringent than in our previous analysis. Therefore, assuming that mt≳ 170 GeV, if the lightest chargino mass bound were to be pushed up to 82 GeV, the sign on the Higgs mixing term μ in the no-scale model could well be determined from the ε1–εb constraint to be positive at the 95% C.L. At any rate, better accuracy in the measured mt from the Tevatron in the near future combined with the LEP data is most likely to provide a decisive test of the no-scale SU (5)× U (1) supergravity model.
