A new interlacer is used in this paper to investigate the effect of processing conditions on the properties of interlaced yarn. The experimental results show that number of tangles of interlaced yarn changes little with air pressure from 0.2 mPa to 0.5 mPa, and the number of tangles has a maximum value with yarn speed changing. For two yarn directions of entering and leaving yarn guide of interalcer, the yarn speed for the maximum number of tangles is 400 m/rain and 600 m/rain, respectively. The number of tangles changes with air pressure and yarn speed for two yarn directions is compared.

To mitigate the damage caused by debris flows resulting from heavy precipitation and to aid in evacuation plan preparation, areas at risk should be mapped on a scale appropriate for affected individuals and communities. We tested the effectiveness of simply identifying debris-flow hazards through automated derivation of surface curvatures using LiDAR digital elevation models. We achieved useful correspondence between plan curvatures and areas of existing debris-flow damage in two localities in Japan using the analysis of digital elevation models(DEms). We found that plan curvatures derived from 10 m DEms may be useful to indicate areas that are susceptible to debris flow in mountainous areas. In residential areas located on gentle sloping debris flow fans, the greatest damage to houses was found to be located in the elongated depressions that are connected to mountain stream valleys. Plan curvaturederived from 5 m DEm was the most sensitive indicators for susceptibility to debris flows.

We develop magnetic metallic contaminant detectors using high-temperature superconducting quantum interference devices （HTS-SQUIDs） for industrial products. Finding ultra-small metallic contaminants is an important issue for manufacturers producing commercial products such as lithium ion batteries. If such contaminants cause damages, the manufacturer of the product suffers a big financial loss due to having to recall the faulty products. Previously, we described a system for finding such ultra-smafi particles in food. In this study, we describe further developments of the system, for the reduction of the effect of the remnant field of the products, and we test the parallel magnetization of the products to generate the remnant field only at both ends of the products. In addition, we use an SQUID gradiometer in place of the magnetometer to reduce the edge effect by measuring the magnetic field gradient. We test the performances of the system and find that tiny iron particles as small as 50 × 50 μm^2 on the electrode of a lithium ion battery could be clearly detected. This detection level is difficult to achieve when using other methods.

There are four serious problems in the discriminant analysis. We developed an optimal linear discriminant function （optimal LDF） based on the minimum number of misclassification （minimum Nm） using integer programming （IP）. We call this LDF as Revised IP-OLDF. Only this LDF can discriminate the cases on the discriminant hyperplane （Probleml）. This LDF and a hard-margin SVm （H-SVm） can discriminate the lineary separable data （LSD） exactly. Another LDFs may not discriminate the LSD theoretically （Problem2）. When Revised IP-OLDF discriminate the Swiss banknote data with six variables, we find mNm of two-variables model such as （X4, X6） is zero. Because mNmk decreases monotounusly （mNmk 〉= mNm（k＋1））, sixteen mNms including （X4, X6） are zero. Until now, because there is no research of the LSD, we surveyed another three linear separable data sets such as： 18 exam scores data sets, the Japanese 44 cars data and six microarray datasets. When we discriminate the exam scores with mNm=0, we find the generalized inverse matrix technique causes the serious Problem3 and confirmed this fact by the cars data. At last, we claim the discriminant analysis is not the inferential statistics because there is no standard errors （SEs） of error rates and discriminant coefficients （Problem4）. Therefore, we poroposed the ＂100-fold cross validation for the small sample＂ method （the method）. By this break-through, we can choose the best model having minimum mean of error rate （m2） in the validation sample and obtaine two 95% confidence intervals （CIs） of error rate and discriminant coefficients. When we discriminate the exam scores by this new method, we obtaine the surprising results seven LDFs except for Fisher＇s LDF are almost the same as the trivial LDFs. In this research, we discriminate the Japanese 44 cars data because we can discuss four problems. There are six independent variables to discriminate 29 regular cars and 15 small cars. This data is linear separable by the emission rate （X1）

沉积于中中新世到上新世的浊积砂体是第三纪Niigata弧后盆地的主要油气储层之一 ,该盆地是日本列岛最富产石油的盆地。我们对这些浊积砂体的重矿物进行了详细和系统地分析。首先 ,作者展示了将重矿物分析和沉积作用分析相结合 ,从而得出有关沉积过程的全新观点的实例。沿着位于盆地东缘的上新世早期的浊积砂岩体的垂向和横向取样分析表明 ,砂体东半部重矿物的成分和西半部重矿物的成分不同。重矿物和沉积分析结果表明 ,发育在东半部的浅海陆架浊积砂岩和发育在西半部的深海水下浊积体在上新世早期是相互叠置的。其次 ,作者检验了用重矿物成分作为指标来表征某个特定浊积体的有效性。为此目的特选重位于Ni igata盆地中部的许多浊积砂岩分析研究 ,得出以下结论。 ( 1)基于主要重矿物 ,比如蛋白石、普通角闪石、紫苏辉石和普通辉石的定量综合分析 ,至少可将研究区的浊积砂岩划分为 6种类型 ;( 2 )一个组或段的浊积砂岩包括一种类型或紧密相关的两种类型 ;( 3)研究区不同的组或段通常由不同的重矿物组成构成 ,不同的物源或相同物源下不同的地质事件 (例如火山活动开始期 )可能是这种差异的原因。重矿物分析不仅可作为有价值的常规手段估计物源方向 ,而且可同其他的沉积资料结合来解析沉积过程。

The interaction of soil aggregate dynamics with soil organic carbon is complex with varied spatio-temporal processes in macro-and micro-aggregates. This paper is to determine the aggregation of soil aggregates in purple soils （Regosols in FAO Taxonomy or Entisols in USDA Taxonomy） for four types of land use, cropland [corn （Zea mays L.）], orchard （citrus）, forestland （bamboo or cypress）, and barren land （wild grass）, and to explore their relationship with soil organic carbon in the Sichuan basin of southwestern China. Procedures and methods, including manual dry sieving procedure, Yoder＇s wet sieving procedure, pyrophosphates solution method, and Kachisky method, are used to acquire dry, wet, and chemically stable aggregates, and microaggregates. Light and heavy fractions of soil organic carbon were separated using 2.0 g·mL^-1 HgI2-KI mixed solution. The loosely, stably, and tightly combined organic carbon in heavy fraction were separated by extraction with 0.1 m NaOH and 0.1 m NaOH-0.1m Na4P2O7 mixed solution （pH 13）. The results show that the contents of dry and wet macroaggregates 〉0.25 mm in diameter were 974.1 and 900.0 g·kg^-1 highest in red brown purple soils under forestland, while 889.6 and 350.6 g·kg^-1 lowest in dark purple soil and lowest in grey brown purple soils under cropland, respectively. The chemical stability of macroaggregates was lowest in grey brown purple soil with 8.47% under cropland, and highest in red brown purple soil with 69.34% under barren land. The content of microaggregates in dark purple soils was 587g·kg^-1 higher than brown purple soils, while 655g·kg^-1 in red brown purple soils was similar to grey brown purple soils （651g·kg^-1）. Cropland conditions, only 38.4% of organic carbon was of the combined form, and 61.6% of that existed in light fraction. Forestland conditions, 90.7% of organic carbon in red brown purple soil was complexed with minerals as a form of humic substances. The contents and stability of wet aggregates 〉 0.25

Light-weight composite panels were manufactured using kenaf core particles as core material and kenaf bast fiber-woven sheets as top and bottom surfaces. methylene diphenyldiisocyanate (mDI) resin was used as the adhesive with the resin content of 4% for core particles and 50 g/m2 for bast fiber- woven sheets. The target board densities were set at 0.35, 0.45 and 0.55 g/cm3. The composite panels were evaluated with Japanese Industrial Standard for Particleboards (JIS A 5908- 2003).The results show that the composite panel has high modulus of rupture and internal bonding strength. The properties of 0.45 g/cm3 density composite panel are: mOR 20.4 mPa, mOE 1.94 mPa, IB 0.36 mPa, WA142%, TS 21%. Kenaf is a good raw material for making light-weight composite panels.
