Immobilized metal affinity chromatography (IMAC) was used to separate ovotransferrin (OVT) by a single chromatographic step. Ovotransferrin was bound strongly to immobilized copper ions, while other components of egg white passed through the column. Using acidic pH and/or a strong competing solute, imidazole, ovotransferrin was recovered in 94〜98% pure form as indicated by SDS-polyacrylamide gel electrophoresis and immunoelectrophoresis. The elution profiles from the IMAC column indicated the presence of two forms of ovotransferrin. The capacity of the IMAC column was 20mg OVT/ml copper loaded gel. Saturation of the metal binding sites of ovotransferrin with Fe^<2+> and Cu^<2+> did not interfere with the binding of ovotransferrin to the IMAC column. However, modification of the histidine residues in ovotransferrin with diethyl pyrocarbonate almost completely destroyed the binding to the IMAC column.

The convincing candidate event of the isotope of the 113th element, ^<278>113, and its daughter nuclei, ^<274>111 and ^<270>Mt, were observed, for the first time, in the ^<209>Bi + ^<70>Zn reaction at a beam energy of 349.0MeV with a total dose of 1.7 × 10^<19>. Alpha decay energies and decay times of the candidates, ^<278>113, ^<274>111, and ^<270>Mt, were (11.68 ± 0.04MeV, 0.344ms), (11.15 ± 0.07MeV, 9.26ms), and (10.03 ± 0.07 MeV, 7.16ms), respectively. The production cross section of the isotope was deduced to be55^<+150>_<45> fb(10^<-39>cm^2).

歴史資料・文化財の調査,分析あるいは研究では,分光反射率画像が有効な情報源として期待されている.しかし分光反射率画像は,その取得において従来のRGB画像の場合よりも被写体たる文化財に負担をかけること,取得後のデータ容量が膨大になることなどの問題もあり,現状では必ずしも文化財解析手段として積極的に活用されているという状況にはない.さらに,分光反射率画像が有する膨大な情報の中に,文化財の調査・解析に有効な情報が埋没してしまうことも解決が望まれている課題である.<br>本研究では,クラスタリングと主成分分析を組み合わせる事で分光反射率画像の各画素における特徴抽出を行う手法を応用し,測定によって得られたイコンの分光反射率画像を用いて文化財解析における有効性について検討した.検討手法では,分光反射率画像に対してクラスタリングを行った後,各クラスタにおいて主成分分析を実行する.それによって得られた各クラスタにおける第1主成分のみを用いて,分光反射率の低次元近似を行う.この際,クラスタ数の増加と色差現象の関係を用いてイコンの色彩に関する特徴を抽出し,文化財解析のための特徴抽出への応用について考察した.<br>

To assess the effect of milk on the development of 7,12-dimethylbenz(a)anthracene (DMBA)-induced mammary tumors, 48 female Sprague-Dawley rats treated with DMBA were divided into 3 groups and given 1 of 3 test solutions for 20 weeks as their drinking liquid: milk, estrone sulfate solution or tap water. The milk group showed a significantly great incidence (75%) in tumor development compared with the water group (38%) and was comparable to the estrone sulfate group (69%). Mean tumor number per rat in the milk group was significantly higher than that in the water group (p=0.009). We classified the mammary tumors into three histological types: intraductal papilloma, fibroadenoma, and adenocarcinoma. Although the percent of intraductal papilloma and fibroadenoma was almost same among the three groups, malignant tumor was found only in the milk and estrone sulfate groups. In conclusion, our results indicate that milk as well as estrone sulfate promotes the development of DMBA-induced mammary tumors in rat and could be associated with the occurrence of adenocarcinoma.

We propose an efficient tag collection algorithm utilizing empty time slots in active RFID systems. In the proposed tag collection algorithm, the reader recognizes the existence of empty time slots via carrier sensing, and utilizes the redundant empty time slots to transmit sleep commands to the tags collected, resulting in performance improvement for tag collection. The simulation results show that the proposed tag collection algorithm can reduce the average tag collection time by 12.28%, 12.30%, and 13.31%, for the framed slotted aloha with the fixed 128 time slots and 256 time slots, and the dynamic framed slotted aloha anticollision protocols, respectively.

It is argued that attitude plays a crucial role in motivating EFL learning. Along the same lines researchers in SLA believe that positive attitude facilitates EFL learning while negative attitude hinders it. The present study examines the attitude of male versus female university students as a motivating factor in studying English as a foreign language. The hypothesis set was whether the responses to each individual item significantly varied across the genders which may consequently lead up to better performance. Participants in the study were 84 male, and 102 female university students majoring in courses other than English (Science, Humanities, or Engineering) at The University of Tabriz and The Azad University of Tabriz. A Questionnaire was employed for data collection and the appropriate statistical means were employed for data analysis. Significant differences were found with 4 of the items corresponding to a) Hearing English language spoken, b) Being made to learn English, c) Appearing cosmopolitan as a result of knowing English, and d) Loss of identity as a result of foreign language ability. Implications of the study are discussed.

The fundamental level of ubiquitous computing, which should be achieved in advance to design smart home, is to set up the system to acquire information from the surrounded environments through the sensor network, using RFID and IpV6. These systems, called contextaware technology, are currently used for computer to predict the user's needs and respond to them by getting information from the surrounded environments such as temperature, humidity, light and motion. Since the ratio of residential buildings that are newly constructed is over 70% and these apartments has equipped with the most advanced network infrastructure in the world, the research for the design method like unit plan, using the application of context-aware technology, should be focused on these apartment environments. In this these, various context-aware technologies in ubiquitous computing will be classified and researched to achieve the design method of unit plan design for smart home.

The growth and sporulation of Penicillium roquefortii were studied during solid state cultivations on support. The process involved the use of a porous material, pozzolano, impregnated and continuously fed at a small rate by a concentrated liquid nutritive medium. This system allowed the recovery of the total spores and biomass produced, due to the large average radius, close to 5 μm, of the pores available for the fungal development. The sporulation occurred in two waves, the first beginning when nitrogen limitation appeared. Nitrogen balances showed that this first wave occurred with a sporulation efficiency, defined as the ratio of the nitrogen incorporated into the conidia to the nitrogen assimilated by the mycelium, close to unity. The second wave gave spores that did not contain nitrogen. Carbon balances, established using the stoichiometric equations of the metabolisms that occurred, showed that this second sporulation wave arose in connection with assimilatory growth that took place together with mecelial lysis. This system allowed 7×10^8 active spores/g pozzolano to be obtained, corresponding to 4.7×10^<11> spores/l fermentor at 110 h cultivation.

In the search for antioxidants from microbial organisms, we found that Penicillium roquefortii IFO 5956 produced an antioxidant. This antioxidant was isolated from a culture broth of the strain, and its structure was identified to be 2, 3-dihydroxy benzoic acid (1). The antioxidative activity of 1 was nearly equal to that of tert-butyl-4-hydroxyanisol(BHA).

We shall survey recent progress on algorithm aspect of graph minor theory. One of the main results on Graph Minor Project by Robertson and Seymour is the following. Given a graph G and p pairs of vertices of G for fixed p, there is a polynomial time (actually O(n^3) algorithm to decide if there are p mutually disjoint paths of G linking the pair. If p is part of the input of the problem, then this is one of Karp's NP-complete problems, and it remains NP-complete even for planar graphs. We shall first sketch the algorithm, and explain why the correctness needs * 500 pages to prove. Then we shall focus on applications of this result. Topics include tree-width for planar graphs, 2-path problem (2-linked graph), the odd disjoint cycles, the parity paths problems, Kuratowski's theorem for general surface, nearly-k-bipartite graph problem and algorithm aspect of Hadwiger's conjecture.

An innovation estimation scheme is conceived to solve the intial and divergent problems for an all-accelerometer inertial navigation system (INS).The reformulated unobservable system with six accelerometers mounted diagonally on each surface of a cubic is investigated.An own-ship trajectory estimator produces extra pseudo measurements in position and velocity of the vehicle to help the Kalman filter in achieving convergence subject to unknown initial values.It also provides an upperbound value for the initiation of the platform attitude.A simulation case with arbitray initial values verifies the effectiveness of using this information infusing concept in obtaining a convergent INS state estimation.

A major earthquake (M 6.8, 37.289 N, 138.870E, Depth 13km) occurred on October 23, 2004, at 5 : 56PM (local time) near Ojiya City, Niigata Prefecture, Japan. The JMA seismic intensity of 7 was recorded in Kawaguchi-machi for the first time after seismic intensity meters were installed. Aftershocks with the JMA seismic intensity scale of more than 5 minus had been measured for more than two weeks in the affected area. Forty people were killed, more than 4,500 were injured and more than 100,000 were evacuated for days. The number of totally collapsed houses exceeded 2,800. Strong shaking triggered more than 1,600 landslides, and some of them blocked up river channels in mountain area. The earthquake also caused major damage on civil structures. The Joetsu Shinkansen bullet train was derailed for the first time in its history of 40 years. The number of passengers was 151 and miraculously no one was injured.

シロウリガイ類は深海から採集すると通常2, 3日しか生存せず, 飼育を試みた報告は皆無であった。本研究では, シロウリガイ類の飼育の試みとして, 良好な健康状態で採集し, かつシロウリガイ類の共生細菌のエネルギー源(泥中の硫化水素)を確保するために, 圧力以外の現場環境をできる限り維持した状態で採集する装置のMTコアを開発した。また, シロウリガイ類は高酸素濃度に弱いため, 溶存酸素濃度制御装置により低酸素濃度環境を維持する飼育システムを製作した。シロウリガイとエンセイシロウリガイをそれぞれ相模湾初島沖水深1,150m~1,160mの地点, 石垣島沖の黒島海丘の643mの地点で採集した。採集したシロウリガイは約1週間で死亡したが, 黒島海丘のエンセイシロウリガイは17日間生存した。また, エンセイシロウリガイでは2回放卵が確認された。以上のことから, エンセイシロウリガイは飼育が容易な種と考えられた。
