Abstract: In this study, we established consecutive monitoring methods using UAV in pecan orchards of 64 ha each, in San Simon, Arizona, USA. Activity monitoring, tree height map creation and ground surface temperature analysis of trees by UAV with near infrared (NIR)/TIR camera were conducted for pecan orchards in San Simon, Arizona, USA. Using established continuous monitoring methods, the UAV images of a 3-year-old pecan orchard showed circular traces of alfalfa cultivation prior to installation of pivot irrigation that was previously not observed. Tree growth measurements was compared to the trees planted inside and outside of the circle. Growth and tree health activity was found to be better when the trees were outside of the circle.

Abstract: Absorption and photoluminescence properties of terrylene derivative 7,8,15,16-tetraazaterrylene (TAT) in its solution and crystal phases have revealed rather unusual spectral characteristics that defy classification in terms of simple H- or J-aggregate-coupled systems. TAT readily forms crystalline aggregates by either self-assembly in solution or physical vapor deposition, based on π stacks aligned roughly along the crystallographic a axis. Using a Holstein-style Hamiltonian including both Frenkel and charge-transfer (CT) excitons, the crystal absorption and steady-state photoluminescence (PL) spectra/line shapes are shown to be determined by a competition between long-range Coulombic coupling, which induces H-aggregate behavior, and short-range charge-transfer-mediated coupling, which induces J-like behavior. Such “HJ” aggregates display J-aggregate signatures in the low-energy region of the absorption spectrum and H-aggregate signatures at higher energies, which are in excellent agreement with our expe...

6. Model based optimal control for SWRO process based on pilot plant data

Abstract: Generally, operating values such as reverse osmosis (RO) recovery rates are adjusted to a desired power consumption cost during the initial stage of design. However, the power consumption is dependent on changes in membrane permeability associated with seasonal/daily variations of seawater conditions such as temperature, salinity and potential of Hydrogen (pH). These variations might be a vital contributing factor to the difference from desired cost. In order to solve this problem, it is desirable to develop optimal control which can minimize specific energy consumption (SEC) automatically. This paper proposes an optimal operational approach for tracking a minimum SEC under the variations of seawater conditions. In this approach, numerical simulations are carried out to estimate SEC and determine operating values. Several simulation results demonstrate the effectiveness of the proposed controller compared with the constant RO recovery rate.

Abstract: Exclusive production of ρ0 mesons was studied at the COMPASS experiment by scattering 160 GeV/c muons off transversely polarised protons. Five single-spin and three double-spin azimuthal asymmetries were measured as a function of Q2 , xBj , or pT2 . The sinϕS asymmetry is found to be −0.019±0.008(stat.)±0.003(syst.) . All other asymmetries are also found to be of small magnitude and consistent with zero within experimental uncertainties. Very recent calculations using a GPD-based model agree well with the present results. The data is interpreted as evidence for the existence of chiral-odd, transverse generalized parton distributions.

9. Energy Efficient Heat Treatment for Linerless Hypereutectic Al-Si Engine Blocks Made Using Vacuum HPDC Process

Abstract: Heat treatment standards developed by the aluminum industry over the last several decades are often not well optimized when applied to components cast by high cooling rate processes such as High Pressure Die Casting (HPDC), Low Pressure Permanent Mold (LPPM), Squeeze Casting, etc. The inherently finer as-cast structures should not require long solution times for the effective dissolution of intermetallic phases and the adequate thermal modification of structural constituents. Hence, long and expensive T6 and T7 treatments should not be required. Heat treatment studies involving as-cast laboratory samples with SDAS = 13.6 μm (equivalent to a thick-section HPDC casting) were conducted. Traditional and modified solution and aging treatments were compared. These studies suggest that a reduction of up to 92% in thermal processing time is possible while maintaining and/or improving the cast component’s metallurgical characteristics including hardness (≥75 HRB), dissolution of secondary phases, and spheroidization of the eutectic Si as well as overall homogeneity. Vacuum HPDC of an actual hypereutectic Al-20%Si motorcycle engine block confirmed the potential for significantly reduced heat treatment times, energy consumption, and overall costs.

10. Requirement of voltage-dependent anion channel 2 for pro-apoptotic activity of Bax

Abstract: Mitochondrial membrane permeabilization is central to apoptotic signaling and is directly regulated by the Bcl-2 family of proteins, consisting of anti-apoptotic members and pro-apoptotic members, although the precise mechanisms involved remain elusive. When cells are deficient in both pro-apoptotic multidomain members of this family (Bax and Bak), mitochondrial membrane permeabilization does not occur in response to various apoptotic stimuli. We have previously reported that the voltage-dependent anion channel (VDAC or porin) plays a role in apoptotic mitochondrial membrane permeabilization by interacting with Bcl-2 family members. Here, we have provided additional evidence that VDAC2 is required for pro-apoptotic activity of Bax in the absence of Bak. In the absence of Bak, VDAC2-deficient cells showed strong resistance to various apoptotic stimuli, whereas re-introduction of the Vdac2 gene restored their apoptotic response. Consistently, silencing of VDAC2 in Bak-deficient cells, but not Bax-deficient cells, also conferred resistance to various apoptotic stimuli. In the absence of VDAC2 and Bak, the activation of Bax (assessed by mitochondrial membrane integration, conformational changes and oligomerization) was markedly impaired. Taken together, these findings indicate that VDAC2 is required for pro-apoptotic activity of Bax in the absence of Bak.

Abstract: The Al-20%Si melt heated to 785°C (1445°F) and 850°C (1562°F) exhibited refinement of the primary Si while heating to 735°C (1355°F) produced coarse and heterogeneous primary Si crystals following the solidification process at approximately 1.3, 4.5, 15 and 35°C/s. The primary Si crystals were 40% finer for the samples heated to 850°C (1562°F) as compared with those heated to 735°C (1355°F). Higher cooling rates produced better primary Si refinement and minimized its variation caused by the melt temperature. The secondary dendrite arm spacing (SDAS) was not affected by the melt temperature and was a function of the cooling rate for the given experimental conditions. The SDAS changed from approximately 32 to 22μm for a 1.3 and 4.5°C/s cooling rate and was reduced to approximately 11μm for a 35°C/s cooling rate. Cooling curve analysis was used to analyze the sequence of the metallurgical transformations and fraction liquid development during alloy melting and solidification. The non-equilibrium thermal characteristics under cooling rate up to 15°C/s were analyzed as well. The experimental results were used to optimize the casting process and improve the service characteristics of the vacuum assisted high pressure die casting (HPDC) motorcycle engine blocks.

Abstract: The effect of average cooling rates on the microstructure of the hypereutectic Al–20% Si alloy was investigated using the novel Universal Metallurgical Simulator and Analyzer Platform. The quantitative measurements of the primary Si size and the Secondary Dendrite Arm Spacing of the non-equilibrium α-aluminum as a function of the cooling rates was performed for the laboratory test samples. This research was carried out in order to analyze the microstructure of the high pressure die cast cylinder block and to understand its complex solidification process. The Equivalent Diameter of the primary Si decreased from 89.7 ± 17.3 to 16.5 ± 3.8 μm and the Secondary Dendrite Arm Spacing from 22.1 ± 5.9 to 5.1 ± 0.8 μm with an increase in the cooling rate from 4.9 to 82.9 °C/s. Observations of the cylinder block microstructures revealed that the primary Si size was nearly identical at the subsurface and the centre locations of the bore wall. The Secondary Dendrite Arm Spacing of the non-equilibrium α-aluminum phase as well as the eutectic Si size was significantly smaller at the subsurface of the bore wall. Based on the UMSA laboratory measurements it was determined that the primary Si in the engine bore wall (both at the subsurface and the centre) nucleated as a first phase from the liquid melt at a cooling rate of approximately 72–74 °C/s. It was found that the non-equilibrium α-aluminum dendrites at the engine bore wall subsurface nucleated from the semi-solid melt at a cooling rate of approximately 85 °C/s, while at the centre of the bore wall at approximately 49 °C/s. Research revealed that some primary Si particles nucleated from the beginning of the melt pouring into the shot sleeve prior to the injection process while the α-aluminum dendrites and eutectic Si nucleated in the die cavity. Therefore, it was proven that the injected hypereutectic Al–20% Si liquid melt had solid primary Si particles.

Abstract: Thermal analysis data were gathered to control the hypereutectic microstructure of the die-cast Al–20% Si cylinder block at a cooling rate of 1 °C/s. The liquidus temperature was approximately 691 ± 2.2 °C, the nucleation temperature of the Al–Si eutectic was approximately 567.1 ± 1.9 °C and the nucleation temperature of the Cu- and Mg-enriched eutectic was approximately 513.6 ± 1.4 °C. The fraction solid increases linearly from 0 to 21.6% when the temperature decreases from 691 to 567.1 °C. During the Al–Si eutectic growth the fraction solid rose to approximately 70% within a very narrow temperature range of 14 °C. The solidus temperature was recorded to be 479.9 ± 3.3 °C. The total solidification range for the investigated alloy was approximately 211 °C. The rapid quenching experiments during the alloy melting cycle revealed the dissolution of the primary Si particles with the increasing temperature followed by complete melting when the liquidus temperature were exceeded (i.e., 710.9 °C). It was found that a minimum superheat temperature of 80 °C was needed to achieve the adequate refinement of the primary Si particles as a combined effect of thermal and chemical modification. The results provided an extensive understanding of the thermal characteristics for the newly developed hypereutectic Al–20% Si alloy and might be used to optimize the liquid metal handling on the foundry floor with respect to obtaining the required alloy microstructural and service characteristics.

Abstract: In Japan, reclaimed wastewater has been recycled widely for non-potable urban applications and it is to be used for sprinkling roads to mitigate heat island in urban areas. To assess the heat island mitigation effects of the sprinkling reclaimed wastewater on water retentive pavement, we carried out a survey at Shiodome-District, Tokyo. The temperatures of air and roads, humidity, and WBGT (Wet-bulb globe temperature) were measured and heat flux was estimated to compare the condition of the areas with/without sprinkling. The following results were obtained. 1) Sprinkling reclaimed wastewater decreased the road surface temperature by 8 degrees during the daytime and by 3 degrees at night: temperatures equal to those on planting zones. Nevertheless sprinkling was done only in the daytime, the temperature decrease effect was not only obtained during the daytime: it continued through the night, due to the water retentive pavement. 2) Sprinkling reclaimed wastewater reduced the amount of sensible heat flux and increased that of latent heat flux. These results suggest that sprinkling reclaimed wastewater on water retentive pavement can effectively mitigate the heat island phenomenon.

Abstract: With the implementation of Pollutant Discharge and Transfer Register (PRTR) in fiscal 2003, information on the quantity of chemical substances discharged annually from each business is released in Japan. Such information is expected to lead to heightened public concern about the presence of chemical substances in environment. This paper showed the effects of using PRTR data for managing chemical risk in a water environment communicating among stakeholders based on the results of the case study held in Japan. First, it was possible to identify the discharge sources using PRTR and related data for the chemicals such as Zn and NPs which were shown that they had relatively high risks based on the survey in a model area. Second, it was suggested that the chemical risk communication among the stakeholders including people using PRTR and related data would be a good way to encourage environmental activities of businesses, and to build a good relationship among stakeholders including people who have anxiety about chemical risk.

Abstract: The growth of S. aureus and the production of staphylococcal enterotoxin A (SEA) in skim milk concentrates stored at inappropriate temperatures in a recovery milk tank (tank for excess concentrated skim milk) used in the manufacture of skimmed milk powder were investigated. Also, it was estimated if a possible outbreak of food poisoning would occur if the contaminated skimmed milk powder was used in the manufacture of processed milk. Skim milk concentrates with milk solid content of 15, 25, and 35% were inoculated with S. aureus at 1-2 log CFU/ml and incubated at 15, 25, or 35 degrees C for 0 to 24 h with or without shaking. Bacterial growth and the level of SEA production were measured. At 35 degrees C with shaking, there was a significant difference (p0.05) in one way layout analysis of variance, and it was demonstrated that the growth of S. aureus and SEA production could be milk solid content-dependent. Shaking accelerated the growth of S. aureus and SEA production at 35 degrees C. Generally, skim milk powder is produced by mixing a set percentage of skim milk concentrates (recovery milk) from the recovery milk tank into raw milk. If recovery milk contaminated with S. aureus at levels of 1-2 log CFU/ml is kept at 15 to 35 degrees C due to a power failure, it was estimated that processed milk consumption of 670-1200 ml, 420-1500 ml and 18-83 ml would trigger the onset of food poisoning symptoms when skim milk concentrates (recovery milk) are stored at 25 degrees C for 24 h, 35 degrees C for 10 h, and 35 degrees C for 24 h, respectively, during the production of the skim milk powder. Based on these consumption levels, it was concluded that, if recovery milk cannot be refrigerated and is stored at room temperature (25 to 35 degrees C), it must be used within 8 h and preferably within 6 h.

Abstract: Exclusive production of $\rho^0$ mesons was studied at the COMPASS experiment by scattering 160 GeV/$c$ muons off transversely polarised protons. Five single-spin and three double-spin azimuthal asymmetries were measured as a function of $Q^2$, $x_{Bj}$, or $p_{T}^{2}$. The $\sin \phi_S$ asymmetry is found to be $-0.019 \pm 0.008(stat.) \pm 0.003(syst.)$. All other asymmetries are also found to be of small magnitude and consistent with zero within experimental uncertainties. Very recent calculations using a GPD-based model agree well with the present results. The data is interpreted as evidence for the existence of chiral-odd, transverse generalized parton distributions., Comment: 14 pages, two tables, 5 figures, bibliography updated

Abstract: Summary Aim This large-scale study was designed to investigate the incidence of gastric cancer after Helicobacter pylori (H. pylori) eradication in Japan. Methods This study was a retrospective multicentre study performed at 23 centres in Japan. Patients in whom H. pylori had been successfully eradicated and those in whom the infection persisted were entered into the study if they had undergone an upper endoscopic examination at least once a year for five consecutive years. The incidence rates of gastric cancer during follow-up were compared between those whose infections had been successfully eradicated and those with persistent H. pylori infection. Results Three-thousand twenty-one patients were enrolled. The median follow-up was 7.7 years for the infected group and 5.9 years for the eradicated group. Gastric cancer developed in 23 (1%) of those in whom H. pylori was successfully eradicated compared with 44 (4%) of those with persistent H. pylori infection (OR = 0.36; 95% CI = 0.22–0.62). Conclusion This large-scale retrospective clinical study in Japan, which has a high mortality rate for gastric cancer, indicates that H. pylori eradication may prevent the development of gastric cancer.

Abstract: The annual quantity of discharge of 354 chemical substances from each business has been released based on PRTR law in Japan since 2003. MLIT and municipalities should be responsible for managing chemical risk in public water bodies through communication with stakeholders, such as the public and businesses. However, it is economically difficult to measure the discharge loads and behaviour of all chemical substances and reveal which substances should be particularly managed in each basin. NILIM has begun studies on survey methods to understand the discharge and behaviour of chemical substances in each basin based on PRTR information, and to conduct risk management of chemical substances in cooperation with stakeholders such as the public and businesses. We selected 30 chemical substances, such as those listed or nominated in environmental criteria and endocrine disrupters, collected the volume of discharge of chemical substances from public and industrial wastewater treatment plants using PRTR information, and surveyed their behaviour in the river in the model area. As a result, the discharge of 12 chemical substances were reported in PRTR, and 17 substances were detected in the river. Some inorganic compounds were detected intensively near discharge sites reported in the PRTR. But some organic compounds and endocrine disrupters, such as oestrone, were detected although their discharge was not reported in the model area in the PRTR. It suggested that PRTR information is useful to identify hot spots, but further study is needed to understand the discharge of chemical substances from small businesses, farmland and houses.

Abstract: Staphylococcus aureus enterotoxin that may be contained at low concentrations in milk and dairy products can cause food poisoning. To detect this enterotoxin at low concentrations, samples should be concentrated. We evaluated the performance of centrifugal ultrafiltration method (UF) in comparison with trichloroacetic acid precipitation method (TCA) for the concentration of S. aureus enterotoxin in milk and dairy products. S. aureus enterotoxin A (SEA) were added at various concentrations to ultra high-temperature heating process (UHT) milk, UHT concentrated skim milk, UHT skim milk powder, low heat-treated (LH) skim milk powder, and raw milk. SEA was concentrated by TCA and UF once a day on a total of 3 days by different researchers to prepare test solutions. The fluorescence value (TV) of test solutions was determined using an immunofluorescence autoanalyzer (miniVIDAS), and the linearity and slope of the regression line, relative standard deviation (RSD(RW)) at each added concentration, detection limit (DL), quantification limit (QL), and the recovery rate by each concentration method were obtained according to the guidelines of the International Conference on Harmonization (ICH). The slope of the regression line obtained by UF was steeper than that by TCA for all dairy samples excluding LH (74 degrees C, 20 s) skim milk powder. RSDRW, DL, and QL obtained by UF were comparable to or more excellent than those obtained by TCA. The procedure of UF was simpler than that of TCA. The recovery rate and rapidity were similar between the two methods. The DL and QL of enterotoxins other than SEA in dairy products by UF or TCA were estimated based on the DL and QL of SEA. In this estimation, consideration was given to reactions between each enterotoxin and its antibody, and also to the immunoactivity maintenance rate of each enterotoxin after addition of trichloroacetic acid in TCA. The estimated values were similar to those obtained by experiments using enterotoxin C1 (SEC1). UF using a centrifugal ultrafiltration membrane can be more readily performed and similar to or more reliable than TCA. UF combined with a miniVIDAS can be used for quantitative routine analysis.

Abstract: Non-potable urban water reuse is Japan's main water reuse practice, which includes water for environmental uses, in-stream flow augmentation, toilet flushing, and industrial reuse. On-site water recycling systems reclaim wastewater on site as well as harvest rainwater in one or more large buildings and distributing the reclaimed water within the buildings for non-potable reuse. Based on our survey conducted in 1999 on current status of on-site water recycling systems in 23 wards of the Tokyo Metropolitan Government District, the following findings are reported in this paper: (1) on the average, 61% of non-potable water demand is met by reclaimed water, and the deficit is made up by tap water from city water supply, (2) biological treatment or ultrafiltration processes can provide reliable treatment and suitable water quality. Some technical problems such as odor from on-site treatment facilities have occurred in a few buildings, (3) there has been no serious accident involving human health by accidentally ingesting reclaimed water, and (4) there is a scale merit in the construction cost of on-site water recycling systems. An on-site wastewater recycling system larger than 100 m3/d is more economically justifiable when compared to a conventional domestic water supply system. An on-site water recycling system can provide an effective, safe, and economical urban water resource for non-potable water reuse applications.

Abstract: We have measured 139La NQR spectra and the nuclear spin-lattice relaxation rate for the highest (±7/2↔±5/2) and the middle (±5/2↔±3/2) NQR lines in the parent compound of high-Tc superconductor, La2CuO4, in a wide temperature range up to 800 K. From the abrupt increase of the quadrupole frequency VQ just below the tetra-ortho structural transition temperature TOT which comes from the staggered tilt of the CuO6 octahedra, the critical exponent is evaluated to be 0.4 which is close to 0.5 expected β in the standard mean field approximation for second order phase transition. In higher temperature than TOT, the nuclear spin-lattice relaxation at La site is dominated by the quadrupole relaxation, not reflecting the critical spin dynamics in the CuO2 plane. We successfully discriminate the two types of quadrupole relaxation rate, WQ1 and WQ2. The relaxation rate WQ2 is one order of magnitude larger than 1 and increases with the critical exponent α ⁓1.19 toward TOT

Abstract: Myotonic dystrophy (DM; OMIM 160900, also known as dystrophia myotonica, myotonia atrophica and Steinert disease) is an autosomal dominant myotonic myopathy associated with abnormalities of other organs, including eyes, heart, endocrine system, central and peripheral nervous systems, gastrointestinal organs, bone, and skin.1 The mutation underlying DM is an expansion of an unstable cytosine-thymine-guanine (CTG) trinucleotide repeat in the 3' untranslated region of the myotonic dystrophy protein kinase (DMPK) gene in chromosome 19q13.3.2-4 In 1994, Thornton et al.5 described an autosomal dominant disorder similar to DM without CTG repeat expansion at the DM locus. Ricker et al.6 named this disease "proximal myotonic myopathy" (PROMM; OMIM 600109) because of predominantly proximal muscle weakness without atrophy as opposed to the distal muscle involvement seen in DM. Subsequently, Meola et al.7 described a variant of PROMM with unusual myotonic and myopathic features, which they named "proximal myotonic myopathy syndrome," and Udd et al.8 described a PROMM-like family with dystrophic features, which they named "proximal myotonic dystrophy" (PDM). Researchers at the University of Minnesota9,10 found another multisystemic myotonic disorder that closely resembles DM with distal muscle weakness but no CTG repeat expansion. Because of the close phenotypic resemblance to DM, they called this disease "myotonic dystrophy type 2" (DM2; OMIM 602668). In 1998, Ranum et al.9 assigned the DM2 locus to chromosome 3q in a large kindred. Shortly after that, Ricker et al.11 found that the majority of German PROMM families show linkage to the DM2 locus. PDM was also mapped to this region (Krahe and Udd, personal communication, 1999). Whether PROMM, PDM, and DM2 represent different phenotypic expressions of a disease caused by the same mutation or if they are allelic disorders remains to be determined. It is also possible that these disorders are caused by mutations in different genes that are closely linked in the chromosome 3q region.12 Furthermore, the disease loci in some typical PROMM families11 and other families with multisystemic myotonic disorders have been excluded from both DM and DM2 loci. Because of the genetic and phenotypic heterogeneity in this group of disorders, it became necessary to establish a new nomenclature foreseeing the future discovery of new disease loci and phenotypic variability.

Abstract: The Chinese native rice cultivar 'Maowangu' expresses a high level of resistance to many races of rice blast (Pyricularia grisea) collected from North China and Japan. 'Maowangu' was crossed with 10 Japanese differential cultivars and the susceptible Chinese cultivar 'Lijiangxintuanheigu' (LTH). Allelism tests were conducted in the F 2 populations with rice blast races. The resistance of 'Maowangu' was governed by two dominant genes which were non-allelic to the resistance genes at seven loci: Pi-a, Pi-i, Pi-k, Pi-z, Pi-ta, Pi-b, and Pi-t. To identify the two resistance genes, two F 3 lines of 'Shin 2/Maowangu' segregating 3R:1S were selected for linkage tests in 1994. One was linked to marker genes C and Amp-3 on chromosome 6 with recombination frequencies of 35.8 ± 6.4% and 42.1 ± 6.2%, respectively, and the other to Amp-1 on chromosome 2 with a recombination frequency of 37.6 ± 6.0%. To confirm these results, two F 3 lines of LTH/Maowangu' were selected for linkage tests in 1995. The one was linked to Amp-3, and other was linked to Amp-1, with recombination frequencies of 36.9 ± 3.1% and 34.3 ± 3.2%, respectively. The two genes on chromosomes 6 and 2 were designated Pi13(t) and Pi14(t), respectively.

Abstract: In situ observations using transmission Laue X-ray photographs taken during 583 K compression tests were used to compare the restorative process of 99.999 mass% aluminum to that of 99.99 mass% aluminum. A regular multipeak stress oscillation, typical of dynamic recrystallization, was generated in 99.999 mass% aluminum, while monotonous work hardening, typical of dynamic recovery, were present in 99.99 mass% aluminum. Spot patterns as well as coarse recrystallized grains containing subgrains confirmed dynamic recrystallization in the 99.999 mass% aluminum. The dynamic recovery of 99.99 mass% aluminum was confirmed by asterism patterns and equiaxed subgrains. Dynamic recrystallization was found to take place only in the high purity range above 99.999 mass%. This dynamic recrystallization was considered to be the results of discontinuous dynamic recrystallization which is well known in Cu, Ni and γ-Fe.

The survey was carried out at Tadotsu Town in Japan where recycled water is used for augmenting artificial streams to restore habitats for firefly regarded as a symbol of “clean water” and to provide opportunity for environmental education such as firefly-watching. Marginal willingness-to-pay for the artificial streams for preserving habitats for firefly, securing hygienic safety to allow body contact, enhancing landscape and providing opportunity for environmental education were estimated at 4,419 Japanese yen (JPY) (US$44), 1,375 JPY (US$14), 4,094 JPY (US$41) and 918 JPY (US$9) per household per year. Those who knew or visited the streams had higher marginal willingness-to-pay for preserving aquatic habitats. And those who attended firefly-watching had high marginal willingness-to-pay for both of preserving aquatic habitats and securing hygienic safety. The results indicated the importance of education at the streams such as firefly-watching for public understanding in habitat preservation and hygienic safety of recycled water.

Abstract: Heterochromatin distribution in barley chromosomes was investigated by analyzing the C- and N-banding patterns of four cultivars. Enzymatic maceration and air drying were employed for the preparation of the chromosome slides. Although the two banding patterns were generally similar to each other, a clear difference was observed between them at the centromeric sites on all chromosomes. Every centromeric site consisted of N-banding positive and C-banding negative (N(+) C(-)) heterochromatin in every cultivar examined. An intervarietal polymorphism of heterochromatin distribution was confirmed in each of the banding techniques. The appearance frequencies of some bands were different between the two banding techniques and among the cultivars. The heterochromatic differentiation observed is discussed with respect to cause.

Abstract: It was demonstrated that G-bands are unequivocally present in plant chromosomes, in contrast to what had been formerly believed by plant cytologists. Maize chromosomes prepared by an enzymatic maceration method and treated with trypsin or SDS showed clear G-bands spreading along the chromosomes. The most critical point during the G-banding procedures was the post-fixation with glutaraldehyde solution. Banding patterns were processed by using the chromosome image analyzing system and a clearer image was obtained. Gbanding technique and the image manipulation method described here can be applied to many plant species, and would contribute new information in the field of plant cytology and genetics.

Subjects: Cracking, Compressive strength, Materials science, Deflection (engineering), business.industry, Ultimate tensile strength, Shear stress, Structural engineering, Composite material, business, Failure mode and effects analysis, Finite element method, Stress concentration
Abstract: Cracking at a cooling hole is a typical die failure mode in a high-pressure die-casting (HPDC) die. We simulated the thermal distortion of a die considering the HPDC machine deflection and revealed a stress concentration at the cooling hole. The stress concentration at the cooling hole changes after injection or after spraying and blowing air. The cooling hole top remains in a compression stress state 5, 10, and 20 mm deep from the die surface, but the stress amplitudes are higher when the depths are shallower. It was suggested that cracking takes place due to the high compressive stress and that the shear stress assists the propagation of the initiated crack. On the other hand, the stress condition at the R portion of the cooling hole is always a tensile state, but the mean stress and stress amplitude values were not found to be in the range that causes fatigue fracture. It was demonstrated that the developed analysis is valuable in designing the cooling hole of an HPDC die.

Abstract: A low-complexity but high-performance SiGe:C BiCMOS technology is realized by conventional simple LOCOS isolation and non-selective SiGe:C epitaxy with optimized impurity profiles. Stress-induced misfit dislocations found in the SiGe:C layer on LOCOS-patterned wafers were successfully eliminated by optimizing the epitaxial process. This, in combination with optimization of HBT impurity profiles, produced a 99% yield of 10000 parallel arrays with an f/sub Tmax/ of 101 GHz. The HBT has been successfully integrate in a 0.25 /spl mu/m CMOS with passive components, which is suitable for low-cost RF mixed-signal applications.

Abstract: We studied Zn-substitution effect on the high-T_c superconductors, underdoped La_{2-x}Sr_xCu_{1-y}Zn_yO_4 (x=0.10; y=0, 0.01, 0.02), optimally doped (x=0.15; y=0, 0.02), and overdoped (x=0.20; y=0, 0.03, 0.06) in a temperature range of T=4.2-300 K, using Cu nuclear quadrupole resonance (NQR) spin-echo technique. We found full disappearance of the Cu NQR signals for the Zn-substituted, Sr-underdoped x=0.10 samples below about 40 K, partial disappearance for the Sr-optimally doped ones below about 50 K, but not for the overdoped x=0.20 ones. From the Zn-doping, the Sr-doping and the temperature dependence of the wipeout effect, we associate the wipeout effect with Zn-induced Curie magnetism or its extended glassy charge-spin stripe formation., Comment: 7 pages, 8 figures, to be published in J.

Abstract: We report a systematic study of Zn-substitution effect on Cu NQR spectrum for high $T_c$ superconductors La$_{2-x}$Sr$_x$Cu$_{1-y}$Zn$_y$O$_4$ from carrier-underdoped to -overdoped regimes (polycrystalline samples, $x$ =0.10, 0.15, and 0.20). We observed no appreciable wipeout effect for the overdoped samples, a gradual and partial wipeout effect below about 80 K for the optimally doped ones, and very abrupt and full wipeout effect below about 40 K for the underdoped ones. The wipeout effect indicates a highly enhanced spectral weight of Cu spin fluctuations at a low frequency. We associate the wipeout effect with a Zn-induced local magnetism far above 40 K and with a localization effect below 40 K., 2 pages, 3 figures, accepted for publication in Physica C (LT23, Hiroshima 2002)

Abstract: One- or three-month repeated oral dose toxicity studies of Cefmatilen hydrochloride hydrate (S-1090) were conducted in beagle dogs. Doses were set at 25, 100 and 400 mg potency/kg/day in both studies. In both studies, no deaths occurred, and reddish-brown feces (due to chelated products of S-1090 and its decomposition products with Fe3+ in the diet) were observed in all treated groups. A transient excretion of reddish urine was observed in the 400 mg potency/kg group and a slight increase in plasma irons was also observed in the 100 and 400 mg potency/kg groups of both studies. However, as no changes suggesting anemia or hepatic injury were noted in these groups, the change of plasma irons was considered to have no toxicological significance. Plasma S-1090 concentrations increased in a manner less than dose-proportional in both studies. In the one-month toxicity study, no toxicologically significant changes, including the above findings, were noted, so the NOAEL was assessed to be 400 mg potency/kg/day. In the three-month toxicity study, urinalysis in the 400 mg potency/kg group revealed a positive reaction to occult blood and erythrocytes in sediments. In the pathological examinations, submucosal edema, hemorrhage, inflammatory cell infiltration and occasionally focal mucosal thickening were observed in the urinary bladder of the 400 mg potency/kg group. The cystisis was considered to result from chronic stimulation with the metabolite(s) of S-1090 in urine, and the reversibility was demonstrable upon one-month drug withdrawal. From these results, the NOAEL of S-1090 in the three-month toxicity study was assessed to be 100 mg potency/kg/day.

Abstract: Background Anti-Wa antibodies were first reported in patients with systemic sclerosis (SSc) as autoantibodies reactive with a 48kDa transfer RNA-associated protein.1 However, the nature of the Wa antigen has not been clarified so far. Objectives To identify and characterise the Wa antigen by molecular cloning using anti-Wa serum as a probe. Methods Molecular cloning of the target Wa antigen was performed using lambda gt11 cDNA library constructed from human liver mRNA and anti-Wa protoype serum as a probe. Bound antibodies were eluted from the fusion proteins of the isolated clones expressed in E.coli and were used for RNA-immunoprecipitation assay. The reactivity of fusion proteins prepared from lysogenic E.coli Y1089 carrying the recombinant phages were examined using five sera that were proved to have anti-Wa antibodies in double immunodiffusion assay. The cDNA inserts of the isolated clones were sequenced, and the detailed homologies of nucleotide and amino acid sequences were analysed through the BLAST server at NCBI DNA databank. Anti-Wa antibodies in sera from patients with various rheumatic diseases were detected by immunoblot analysis using the fusion protein from the positive clone. Results 10 positive clones were recognised by the probe serum. In RNA-immunoprecipitation, the affinity-purified antibodies from only one clone (termed Wa-1) immunoprecipitated transfer RNA from HeLa cell extracts. In immunoblot study, the Wa-1 fusion protein was recognised by all five sera that were proved to have anti-Wa antibodies. These data confirmed that the Wa-1 clone encoded for the Wa antigen. The nucleotide sequence and deduced amino acid sequence of the 0.7-kb insert cDNA of Wa-1 were completely identical with the C-terminal part of NEFA (named after DNA-binding domain, two EF-hands, Acidic amino acid rich region)/nucleobindin-2.2 In immunoblots using the Wa-1 fusion protein, autoantibodies to Wa (NEFA/nucleobindin-2) were detected in 3 of 21 SSc (21%), one of 10 RA (10%) and one of 16 SLE sera (6%). However, neither RA nor SLE sera immunoprecipitated transfer RNA from HeLa cells, while all 3 SSc sera immunopricipitated transfer RNA, suggesting the diversity of autoepitopes among patient sera. Conclusion These results demonstrated that the autoantigen recognised by anti-Wa antibodies were proved to be identical with NEFA/nucleobindin-2. References Miyachi K, et al.

Abstract: We report here a case of interstitional pneumonia (IP) associated with amyopathic dermatomyositis (DM). In August, 1998, a 53-year-old Japanese man was admitted to our hospital because of fever, polyarthritis and erythematous heliotrope eruption and Gottron's sign without any symptom of myositis. Serum CK level and EMG were normal. Jo-1 antibody was negative. Chest computed tomography (CT) revealed IP at both lung base areas. The patient was diagnosed as amyopathic DM with IP. When IP rapidly progressed, methylprednisolone pulse therapy and oral high dose prednisolone were not effective. High-dose intravenous cyclophosphamide seemed to be transiently effective, but oral cyclosporine A was not effective. The patient was died of respiratory failure in October 1998. During the course, we measured serum levels of LDH, sIL-2 R, s-ICAM-1 and KL-6, KL-6 could be a sensitive parameter of IP activity.
