The development of targeted therapies for cancer remains an enormous challenge. Despite advances in the understanding of molecular pathways involved in tumor growth and rational design of new agents, a gap exists between drug development and patient survival. Ligand-directed delivery of drugs to the tumor is one appro…
先進的再処理・放射性廃棄物処理においてはアクチノイド核種の選択的分離回収技術の高度化が重要な課題とされている。長寿命核種の核変換処理のための第一のステップであり，さらに核不拡散および廃棄物処分の負担軽減，環境負荷低減および資源化・有効利用の観点からも高度分離技術の開発は期待されている。イオン交換技術は，アクチノイド分離の先駆的な技術と位置づけられており，基礎的に選択性を評価するとともに，実用化に向けたイオン交換プロセスの合理化や簡素化の研究が各国で精力的に展開されている。近年より精密な核種分離手法の開発に期待がかけられており，選択的なイオン交換技術の高度化は極めて重要な意義を有している。 本報では，(1)アクチノイド分離の目的と効…
In this paper we use the property of diatoms as bioindicators, to indentify which WQC is the taken sample using machine learning classifying algorithm - CN2. Important physical-chemical parameters such as conductivity, saturated oxygen and mostly used pH have defined range in which water class they belong. These physi…
According to 1st order slip velocity boundary, modified Reynolds equation for microscale gas journal bearings is presented with consideration of effective viscosity of gas under rarefied condition. Modified Reynolds equation is solved using the finite difference method. Non-dimensional pressure distribution, load capa…
Porous polyvinylidene fluoride (PVDF) membranes with various structures were prepared via phase inversion using DMF as solvent. Polyethylene glycols (PEG) with three different concentrations and molecular weights were used. Effects of PEG on the structure and performance of porous membranes were investigated. The morp…
Best estimate analysis method for the loss of Residual Heat Removal (loss-of-RHR) event during the mid-loop operation is being conducted along the Code Scaling, Applicability and Uncertainty (CSAU) evaluation methodology. The analysis method uses RELAP5/MOD3.2 as a best estimate analysis code. One of the important pro…
The effect of boron on the abrasive wear behavior of the austenitic Fe-Cr-C-Si-B hardfacing alloys was investigated with varying boron concentration. It was found that the abrasive wear resistance of the hardfacing alloys increased up to 50% compared to that of boron free alloys with increasing boron concentration. Th…
An aprE mutant from B. subtilis 168 lacking the connecting loop Leu(75)-Leu(82) which is predicted to encode a Ca(2+) binding site was constructed. Expression of the mutant gene (aprEDeltaLeu(75)-Leu(82)) produced B. subtilis colonies lacking protease activity. Intrinsic fluorescence analysis revealed spectral differe…
We measure 150 fs time-resolved 800 nm pump/ 1300 nm probe differential reflectivity and transmissivity of graphitic samples, ranging from one (graphene) to >100 layers (graphite). Carrier cooling kinetics vary gradually with number of layers.
We report the experimental observation of a superheated granular system: A vibrated hexagonal monolayer that persists as a crystal for some time until it spontaneously evaporates. We observe the nucleation sites of the gas and follow the dynamics of the evaporation, where mean lifetimes of the metastable state are obt…

During a 3 year period, the Natural Radioactivity Sector of the Geophysics Department has conducted radon concentration measurements in the soil and indoors in Tirana. The measurements have covered a 40 km2 area. Radon measurements have been made in 160 squares. In these 160 squares, we have made 2400 measurements of…
In order to develop a new eco-friendly non-leaded free cutting steel, it is important to get good machinability by the use of manganese sulfide (MnS) inclusions in place of lead. In this study, the effect of MnS morphology on the surface roughness was assessed in a turning test used two steels containing different typ…

Wide gap brazing (WGB) is a cost effective and reliable means to repair gas turbine hot section components with defect sizes exceeding 0.3 mm. However, it has been shown that WGB joints of nickel-based superalloys suffer from reduced ductility and thermal fatigue life due to the presence of brittle intermetallics and…
Sodium hydrogencarbonate (NaHCO 3 ) has been recrystallised hydrothermally using a cooling ramp from 250 °C to 190 °C at 0.069 GPa, and investigated by single crystal X-ray diffraction at room temperature and pressure. Representative crystal data are: monoclinic, space group P 2 1 / n , Z = 4, a = 7.4688(4), b = 9.684…
In this study, the different curvature of surface micromachined planar curved grating is systematically investigated. The crossed grating with various pitches was also explored. The planar curved grating and crossed grating were fabricated using multi-user MEMS processes (MUMPs) provided by MEMSCAP Inc. The angular se…
Surface micro dents may act as lubricant reservoirs to reduce friction and wear in sliding and rolling contact applications. Surface patterning has become a valuable technique for fabricating micro dents. Alternative methods such as micromachining present obvious limitations in comparison with laser shock peening (LSP…
Polymers are well known for their non-equilibrium deviatoric behavior. However, investigations involving both high rate shock experiments and equilibrium measured thermodynamic quantities remind us that the volumetric behavior also exhibits a non-equilibrium response. Experiments supporting the notion of a non-equilib…
Reducing the weight of a machine structure is an increasingly important consideration both for the conservation of resources during production and for the energy saving during operation. With these objectives in mind, thin-walled ductile cast iron has recently been developed. Because rapid cooling could result in brit…
