Swelling and subsequent deformation of membranes by water wetting are regarded as a prime drawback of hydrophilic polyurethane breathable film. Fluoroalkylated surface was prepared by reacting the film with hexamethylene diisocyanate(HDI) and 2-perfluorohexyl ethanol. IR spectra and XPS results showed that the fluoroa…
Bu çalışmada; üç fazlı reaktörlerde kolon uzunluğunun basınç düşüşüne etkisi incelendi. Aşağı doğru paralel su ve hava akımı şartlarında dolgu maddesi olarak cam küreler kullanıldı. İki farklı sıvı ve üç farklı gaz akış hızlarında çalışılarak kolonun üç farklı yerinde basınç değerleri ölçüldü. Ölçülen değerlerin farkı…
The aim of this study was to modify a synthetic clay with MgO and a non-ionic surfactant (Igepal CA-720), impregnated with Cu or Fe to evaluate the H2S removal. The Cu and Fe content was: 1.0; 8.0 and 15wt. %, bimetallic Cu-Fe solids were also prepared. The obtained materials were characterized by N2 adsorption, X-ray…
Nikon、Canon 二社で80%に達する199 年代初頭の絶頂期から、国内半導体デバイスメーカの凋落と時を一に国内半導体露光装置メーカNikon、Canon の地盤沈下が続いている。2002 年には着実にシェアを伸ばしてきたASML 社がトップに躍り出た。露光装置はコンタクト露光に始まり、プロキシティ露光、1:1 ミラースキャンから縮小投影露光へ進み、縮小投影露光はg 線、i 線、KrF、ArF と短波長化し、Step&Repeat からStep&Scanに移行してきた。競争は過酷で次世代露光装置の開発に露光装置メーカの命運がかかっている。2000 年前後にはArF 193 nm の次の技術が混沌としていた。ArF 193 n…
We continue a dominant WKB solution of the Schrödinger equation in the classically forbidden region to an outgoing WKB solution in the classically allowed region across a sim- ple (multi-dimensional) turning point, without assuming the analyticity for the potential.This report explains briey the method used in [FLM],…
Bambu merupakan salah satu tumbuhan yang memiliki bentuk batang tinggi, berongga, berbentuk bulat dan memiliki kekuatan yang baik. Penelitian ini bertujuan mempelajari pengaruh proses penyinaran gelombang mikro terhadap pembentukan struktur dan sifat thermal karbon hitam dari bambu ori (Bambusa arundinacea) dan bambu…
La utilització dels ultrasons en sistemes d’adobament vegetal presenta avantatges respecte els sistemes més consolidats en la indústria en l’actualitat: adobaments vegetals dinàmics on s’utilitzen els bombos com a reactor, i adobaments vegetals estàtics o s’utilitzen les tines com a reactor. Els adobaments vegetals di…
Styela (S.) clava (Korean name: miduduk) tunic is produced as a by-product after processing of S. clava. For utilizing this tunic, a konjac containing the tunic extracts was prepared and the qualities evaluated for their color, textural properties, and sensory attributes. The tunic extract was prepared by boiling tuni…
최근 국외의 원자로 상부헤드 CRDM 관통노즐에 일차수 응력부식균열로 인한 냉각수 누출사고가 발생하였다. 일차수응력부식균열은 부식에 민감한 재료, 인장 잔류 응력 및 부식 환경 등의 3 가지 요인의 상호작용에 의해 발생하는 것으로 알려져 있기 때문에 응력 부식 균열 발생 및 균열 진전을 억제하기 위해서는 용접에 의한 잔류응력에 대한 정확한 예측이 선행되어야 한다. 본 논문에서는 국내 Westinghouse 형 원자로 상부 헤드 관통노즐(CRDM)을 대상으로 노즐의 두께 및 형상 비(r o /t)에 따른 노즐 잔류응력 분포 특성에 대해 연구를 수행하였다. 국내에 현존…
Pada tugas akhir ini telah dilakukan analisis perbandingan stabilitas pada operasi towing CPO Barge dengan menggunakan single lead pendant dan flounder plate untuk variasi kondisi muatan penuh, setengah dan kosong. Analisis yang pertama dilakukan adalah menentukan karakteristik gerakan CPO Barge (RAO) di atas gelomban…
Baja St 41 sering kali diaplikasi sebagai bahan dasar pembuatan komponen mesin maupun bahan konstruksi. Sering dijumpai bahwa kerusakan atau kegagalan banyak terjadi pada beban dinamik, walaupun beban berulang yang diterima oleh material masih jauh dari tegangan statis maksimum material. Maka dari itu perlu dilakukan…
Struktur konstruksi badan kapal lambat laun akan mengalami kerusakan. Ketika kapal mengalami kerusakan pada kondisi darurat, pekerjaan las bawah air menjadi hal yang penting. Melalui penelitian ini, dikaji perbandingan laju korosi pada sambungan las material baja karbon rendah yang diberi perlakuan pengelasan di udara…
Structures, vibrational frequencies, and energies of Si2CmN (m = 2–10) clusters have been investigated using the B3LYP density functional theory (DFT) method with a 6-311G* basis set. The character of the chemical bond and thermodynamic stability of isomers has been discussed. The results show that all Si2CmN (m = 2–1…
The standard CPT(Cone Penetration Test), which can be easily performed to investigate in-situ soil engineering properties, has been widely used. CPT are also widely being utilized in centrifuge model tests. In this study, a miniature cone with 10㎜ diameter was developed and its applicability in the centrifuge was eval…
This paper studies the dependence of the ratio of prismatic strength (Rb) from cube strength (R) for high-strength concrete of classes B70... B110. Experiments were carried on the concrete cubes with an edge of 150 mm and prisms with a base 150x150 mm and a height 600 mm. The tendency to reduce the ratio Rb / R with i…
A series of novel imidazole-blocked diisocyanate bioadhesives (IBAs) were synthesized from reaction of toluene 2, 4-diisocyanate (TDI), isophorone diisocyanate (IPDI), hydroxyl-terminated polylactide (HO-PLA-OH), 1,1,1-trimethylolpropane (TMP), and imidazole. Synthesis of IBAs was confirmed by Fourier transform infrar…
In this paper, ZnO thin film was prepared by sol-gel process on glass substrates. The deposited films were dried at 100 and 240 ˚C and then annealed at 300, 400 and 500 ˚C. The two-probe measurement showed that resistance of as-prepared films is very high. The KrF excimer (λ=248 nm) laser irradiation with 1000 pulses,…
