Upper Limits to the Contact Angles of Liquids on Solids (1964)

Graphical plots of the cosine of the equilibrium contact angle vs. the difference in the surface tension of a pure liquid and the critical surface tension of wetting of the solid group data for each liquid into a zone bounded by a straight line passing through the origin (cos Θ = 1; γLV - γc = 0). From the parameters defining this straight line the limiting contact angles for each liquid can be estimated. They indicate that the maximum contact angle possible for water is 156°; for hexadecane, 109°. A rectilinear relation between liquid surface tension and the minimum value of (γLV - γc) required for a surface to exhibit a 90° contact angle can be extended to provide a good fit to available data for a pure liquid metal like mercury.
Comparison of the New Biometer OA-1000 with IOLMaster and Tomey AL-3000 (2013)

Compared with other used clinical instruments the OA-1000 generates accurate results. Although differences were found, the OA-1000 provided results that correlated well with the values of IOLMaster and AL-3000.

Mechanism of poly(methyl methacrylate) fire retardation by Wilkinson's salt (1989)

Abstract The reaction of Wilkinson's salt, CIRh(PP 3)3 , and poly(methyl methacrylate) (PMMA) has been studied. Char formation is observed, and some 30% of the reaction product is nonvolatile at 600°C. In order to understand the pathway of this reaction, the reaction of dimethylglutarate (DMG) and CIRh(PP 3 ) 3 has been studied. A pathway is proposed in which the initial step is the oxidative addition of the rhodium species into a carbon—oxygen bond of the DMG molecule. Six different products have been isolated from this reaction and can be seen to result from the oxidative insertion. This pathway also seems to apply to the PMMA reaction and leads to an interpretation of the results of this reaction and permits one to understand the role of this, and similar, compounds as flame retardants.
Study of local stress, morphology, and liquid-crystal alignment on buffed polyimide surfaces (1996)

The magnitude of local stress applied to a polymer surface in the buffing process, which is a critical method to uniformly align liquid crystals for displays, has been evaluated from the polarizing optical microscopic investigation of nematic liquid crystals in contact with polyimide surfaces which were suitably buffed in order to visualize the individual tracks of the buffing rayon fibers. The estimated magnitude of local stress is most likely to be far greater than the yield stress of the polymer film, thereby causing permanent molecular orientation along the buffing direction. The surfaces of poly(amic acid) and cured polyimide films, subjected to different buffing and cure profiles, have been examined by atomic force microscopy. The ability of these buffed polymer surfaces to align nematic and chiral smectic C (ferroelectric) liquid crystals were also investigated. These studies show that the presence of microgrooves on buffed polymer surfaces is not necessary for alignment of liquid crystals. The contribution of polymer molecules from the buffing fibers, deposited and oriented on the polyimide surfaces during buffing, can also be ruled out. Rather, it is concluded that the liquid-crystal alignment is mainly caused by the anisotropic interactions between liquid-crystal molecules and the polymer segments oriented through plastic deformation, with little contribution from frictional heating. For the alignment of smectics, both the degree of order and mechanical properties of polyimide films are found to be important factors.
Impact Testing of High-Density Semirigid Urethane Foam for Automotive Bumper Applications (1972)

<div class="htmlview paragraph">Semirigid urethane-foam specimens of various high densities were evaluated when subjected to simulated heavy-mass impacts such as in low-speed automobile collisions. The dynamic test results showed excellent material-energy absorption with essentially no compression sets, even after many repeated impacts of high deflection. These findings, coupled together with the well-known tough physical properties of urethanes, provide an outstanding candidate material that can be used to effectively reduce the damage to support structures and contact surfaces, not only in automotive applications but in any other application requiring a reduction of shock forces.</div>
<title>Earth Resources Techniques Applied To Planetary Exploration</title> (1982)

In recent years, the demand for improved management of Earth resources has increased. At the same time, the proven ability of Earth-orbiting satellites to obtain accurate and timely information for this management has been demonstrated several times. Return Beam Vidicons (RBV) and Multispectral Scanners (MSS) are orbiting now, the Thematic Mapper (TM) is slated for a near-term Shuttle launch, and advanced definition is being done to determine technology capability of the next generation Earth resources satellites. This conceptual system will likely utilize "pushbroom" (linear arrays normal to orbital track using the orbital velocity to provide a 2-dimensional map) techniques with one linear array for each of the spectral bands required for information gathering. This discussion takes user requirements, as determined by NASA, and considers the possibility of using a preliminary system derived for those requirements to gather similar information on other planets. Relative levels of solar irradiance, planetary characteristics, and other solar system information have been used to find possible orbits, comparative signal-to-noise, ranges of sun-synchronous orbits, and other information regarding possible operation of this Earth-oriented system for other planets.
Vanadium Oxo Organometallic Species Supported on Silica for the Selective Non-oxidative Dehydrogenation of Propane (2013)

The molecular complex [V(═O)(Mes)3] (1) reacts with silica partially dehydroxylated at 700 °C (SiO2-700) to afford [(≡SiO)V(═O)(Mes)2] (2) as the major surface species, while a bis-grafted surface species [(≡SiO)2V(═O)(Mes)] (3) is obtained on SiO2-200. These surface species were characterized by DRIFT, Raman, 1H, 13C, and 51V solid-state NMR, and XAFS spectroscopy and show an activity in the non-oxidative dehydrogenation of propane at 500 °C. The bipodal surface organometallic complex displays a higher selectivity in propylene in comparison to the monopodal species.
Abstract 112: Nitrated Apolipoprotein Ai/apolipoprotein Ai Ratio Is Increased in Diabetic Patients With Coronary Artery Disease (2015)

Recent studies indicated that protective function of HDL may be more representative than its concentration. Apolipoprotein AI (apoAI), the major protein of HDL, is nitrosylated in vivo to nitrated apoAI (NT-apoAI) that might cause dysfunction. We measured plasma NT-apoAI and apoAI levels in 777 patients with coronary artery disease (CAD) by ELISA, and found that median NT-apoAI/apoAI ratio was significantly higher in diabetes mellitus (DM) (n=327) versus non-diabetic patients (n=450). Further analysis indicated that DM, thiobarbituric acid-reactive substances and C-reactive protein levels were independent predictors of higher NT-apoAI/apoAI ratio. There was negative correlation between NT-apoAI/apoAI and use of anti-platelet and lipid lowering drugs. The cholesterol efflux capacity of plasma from 67 individuals with differing NT-apoAI but similar apoAI levels from macrophages in vitro was negatively correlated with NT-apoAI/apoAI ratio. In conclusion, higher NT-apoAI/apoAI ratio is significantly associated with DM in this relatively large German cohort with CAD and may contribute to associated complications by reducing cholesterol efflux capacity.
Induction of the Mouse κ-Opioid Receptor Gene by Retinoic Acid in P19 Cells (2002)

The mouse kappa-opioid receptor (KOR) gene is expressed in mouse embryonal carcinoma P19 cells and induced by retinoic acid (RA) within 24 h. An RA-responsive cis-acting element is identified within promoter I of the KOR gene. This element contains a GC box, a putative binding site for transcription factor Sp1. Enhanced binding of Sp1 to this GC box correlates with RA induction of KOR gene. Phosphatase inhibitor (sodium pyrophosphate) decreases RA induction of this promoter, whereas hypophosphorylation of Sp1 results in an increase in its DNA binding affinity to this promoter as demonstrated by in vitro gel retardation and in vivo chromatin immunoprecipitation assays. Consistently, the inhibitor of MEK, PD98058, dose-dependently enhances RA induction of this promoter, suggesting that the ERK signaling pathway is negatively involved in the RA induction of mouse KOR gene activities. Collectively, enhanced binding of Sp1 to promoter I of the KOR gene as a result of inhibiting the ERK pathway contributes to RA induction of this gene in P19.

Quantum walk and Anderson localization of rotational excitations in disordered ensembles of polar molecules (2015)

We consider the dynamics of rotational excitations placed on a single molecule in spatially disordered 1D, 2D and 3D ensembles of ultracold molecules trapped in optical lattices. The disorder arises from incomplete populations of optical lattices with molecules. This leads to a model corresponding to a quantum particle with long-range tunnelling amplitudes moving on a lattice with the same on-site energy but with forbidden access to random sites (vacancies). We examine the time and length scales of Anderson localization for this type of disorder with realistic experimental parameters in the Hamiltonian. We show that for an experimentally realized system of KRb molecules on an optical lattice this type of disorder leads to disorder-induced localization in 1D and 2D systems on a time scale $t \sim 1$ sec. For 3D lattices with $55$ sites in each dimension and vacancy concentration $ 90~\%$, the rotational excitations diffuse to the edges of the lattice and show no signature of Anderson localization. We examine the role of the long-range tunnelling amplitudes allowing for transfer of rotational excitations between distant lattice sites. Our results show that the long-range tunnelling has little impact on the dynamics in the diffusive regime but affects significantly the localization dynamics in lattices with large concentrations of vacancies, enhancing the width of the localized distributions in 2D lattices by more than a factor of 2. Our results raise a general question whether quantum particles with long-range tunnelling can undergo quantum localization in 3D lattices with substitutional disorder.
Crystal structure and Hirshfeld surface analysis of the methanol solvate of sclareol, a labdane-type diterpenoid (2020)

The title compound, C<sub>20</sub>H<sub>36</sub>O<sub>2</sub>·CH<sub>3</sub>OH [systematic name: (3<i>S</i>)-4-[(<i>S</i>)-3-hy-droxy-3-methyl-pent-4-en-1-yl]-3,4a,8,8-tetra-methyl-deca-hydro-naphthalen-3-ol methanol monosolvate], is a methanol solvate of sclareol, a diterpene oil isolated from the medicinally important medicinal herb <i>Salvia sclarea</i>, commonly known as clary sage. It crystallizes in space group <i>P</i>1 (No. 1) with <i>Z</i>' = 2. The sclareol mol-ecule comprises two <i>trans</i>-fused cyclo-hexane rings, each having an equatorially oriented hydroxyl group, and a 3-methyl-pent-1-en-3-ol side chain. In the crystal, O<sub>s</sub>-H⋯O<sub>s</sub>, O<sub>s</sub>-H⋯O<sub>m</sub>, O<sub>m</sub>-H⋯O<sub>s</sub> and O<sub>m</sub>-H⋯O<sub>m</sub> (s = sclareol, m = methanol) hydrogen bonds connect neighboring mol-ecules into infinite [010] chains. The title compound exhibits weak anti-leishmanial activity (IC<sub>50</sub> = 66.4 ± 1.0 µ<i>M</i> ml<sup>-1</sup>) against standard miltefosine (IC<sub>50</sub> = 25.8 ± 0.2 µ<i>M</i> ml<sup>-1</sup>).
Radar Waveforms for Suppression of Extended Clutter (1967)

A common problem in waveform design is to adapt the transmitted signal to the target environment in order that the interference from extended fields of scatterers is reduced. This problem is investigated here for the special case of detection of a single target in the ``vicinity'' of an extended clutter space. The paper considers the possibility of confining the matched-filter response in delay and Doppler, or ambiguity function, to a narrow strip with arbitrary orientation in the delay-Doppler plane. It is shown that strict confinement of the response is achievable only with waveforms that are unlimited in both time and frequency domain. With practical waveforms, which are necessarily of finite extent, one merely can trade close-target separability against detectability in the background clutter. Thus, one form of the resolution problem is exchanged against the other. The paper examines these effects quantitatively.
Puits Nomade dans un Reseau de Capteurs : Vers une Collecte Efficace de Donnees (2012)

Les contraintes energetiques dans les reseaux de capteurs necessitent de limiter les operations couteuses sur certains nœuds sans compromettre l'application de surveillance. Nous nous interessons ici au cas d'un puits nomade cherchant a collecter efficacement les donnees du reseau. Nous proposons un mecanisme fonction de deux objectifs : l'energie consommee par le reseau (i.e. proportion de nœuds relais) et l'efficacite du routage (i.e. longueur des chemins). Afin d'ajuster l'equilibre entre le nombre de relais et l'efficacite du routage nous introduisons un parametre regulant ce compromis. Lorsque l'efficacite energetique est le critere prioritaire, notre solution est plus performante qu'une 2- approximation centralisee pour la construction d'un MLST. Lorsque l'efficacite du routage est prioritaire, nos resultats mettent en evidence la faible proportion de relais supplementaires necessaires.
Aerosol Formation During the Microwave Freeze Dehydration of Beef (1985)

Data are obtained from the combined microwave and radiant freeze drying of beef steaks. Causes for the high drying rates are explained by the entrainment of solid ice crystals in the vapor during the low pressure drying. The effects of solid entrainment on dehydration rate and product quality are discussed in terms of the loss of intercellular salts and proteins and tearing of muscle fibers caused by high vapor velocity.
Human monocyte-derived dendritic cells turn into foamy dendritic cells with IL-17A (2015)

Interleukin 17A (IL-17A) is a proinflammatory cytokine involved in the pathogenesis of chronic inflammatory diseases. In the field of immunometabolism, we have studied the impact of IL-17A on the lipid metabolism of human in vitro-generated monocyte-derived dendritic cells (DCs). Microarrays and lipidomic analysis revealed an intense remodeling of lipid metabolism induced by IL-17A in DCs. IL-17A increased 2-12 times the amounts of phospholipids, cholesterol, triglycerides, and cholesteryl esters in DCs. Palmitic (16:0), stearic (18:0), and oleic (18:ln-9c) acid were the main fatty acid chains present in DCs. They were strongly increased in response to IL-17A while their relative proportion remained unchanged. Capture of extracellular lipids was the major mechanism of lipid droplet accumulation, visualized by electron microscopy and Oil Red O staining. Besides this foamy phenotype, IL-17A induced a mixed macrophage-DC phenotype and expression of the nuclear receptor NR1H3/liver X receptor-α, previously identified in the context of atherosclerosis as the master regulator of cholesterol homeostasis in macrophages. These IL-17A-treated DCs were as competent as untreated DCs to stimulate allogeneic naive T-cell proliferation. Following this first characterization of lipid-rich DCs, we propose to call these IL-17A-dependent cells "foamy DCs" and discuss the possible existence of foamy DCs in atherosclerosis, a metabolic and inflammatory disorder involving IL-17A.
Non-destructive tree-ring measurements using a clinical 3T-MRI for archaeology (2019)

For dendrochronology, both high spatial resolution and a wide imaging area are required. However, there has been no study to satisfy these two requirement for a tree-ring measurement method using magnetic resonance imaging (MRI). In this study, we developed a ring-width measurement method (ultra-high-resolution T2 weighted imaging: uHR-T2WI) using clinical MRI that can scan images at high resolution and over a wide sample area for waterlogged wood, by repeating small fields of view (FOV). Incidentally, until now, the method using X-ray computed tomography (X-CT) has been developed for non-destructive ring-width measurement for analysis of wooden cultural heritage and excavated wooden artifacts, and is mainly successful for dried samples with a low moisture content. However, the contrast of X-CT images tends to reduce as the water content increases, and it has been reported that the attempts to visualize waterlogged and PEG-impregnated archaeological oak wood were unsuccessful owing to a low degree of contrast between the water/PEG and the preserved wood (Bill et al., 2012). Actually, the archaeologically excavated wood generally has very high moisture content (400%–800%), thereby reducing the suitability of X-CT for tree-ring analysis. On the other hand, MRI equipment images the density and state of hydrogen nuclei, and so the expected quality of MRI improves as the moisture content of the wood increases. With these factors, to use both modality complementary will be very useful for dendroarchaeology. However, direct comparison of the suitable range of each modality has not been reported. Therefore, we examined the difference between X-CT and MRI related to moisture content of wood, and examined the range of adaptation for each modality as a function of moisture content. By using the proposed method, we then obtained a tree-ring width series and evaluated the usefulness of the proposed method. The uHR-T2WI method was able to obtain tree-ring width series comparable to those of an optical scanner from images acquired at a spatial resolution of 0.05 mm in high moisture content wood. The results show that wood with a high moisture content (e.g., waterlogged wood measured immediately after excavation, or high-water-content lacquered wooden cultural property) can now be successfully analyzed as non-destructive methods with MRI. In conclusion, the complementarity of both MRI and X-CT will be very useful as non-destructive inspection methods for dendroarchaeology. Although further research should consider more wood species, our study suggests that the proposed method will significantly advance the field of dendrochronology, particularly when related to dendroarchaeology.
Glycoalkaloid Content of Mature Green Fruit of Lycopersicon Species1 (1977)

Abstract Total glycoalkaloid (TGA) contents were determined in the mature green fruit of 7 lines representing 6 Lycopersicon species. Significant differences were found among all lines except the L. esculentum entries and among clusters within 6 lines. LA 1028 ( L. chmielewskii Rick, Kesicki, Fobes & Holle) had the highest mean TGA content of 114 mg/100 g fresh weight; 31-St-34 ( L. esculentum Mill.) had the lowest mean TGA content of 7 mg/100 g fresh weight.
