Chirality transfer from atropisomeric chiral inducers to nematic and smectic liquid crystals – synthesis and characterization of di- and tetra-substituted axially chiral binaphthyl derivatives (2012)

The chirality transfer of axially chiral binaphthyl derivatives bearing liquid crystal (LC) moieties at the n,n′ positions (n = 3, 4, 6) of the binaphthyl rings to nematic (N) and smectic (S) LCs is investigated. Chiral nematic LCs (N*-LCs) are prepared by adding a small amount of the chiral binaphthyl derivative into host N-LCs composed of cyanobiphenyl mesogen cores. The binaphthyl derivative with phenylcyclohexyl (PCH) type LC moieties at the 4,4′ positions of the binaphthyl ring [D-4,4′] exhibits a low helical twisting power (HTP) of 11 μm−1. In contrast, those with LC moieties at the 3,3′ and 6,6′ positions of the binaphthyl rings [D-3,3′ and D-6,6′] exhibit high HTPs of 153 μm−1 and 154 μm−1, respectively. Next, the binaphthyl derivatives are added into two types of S-LCs with phenylbenzoate mesogen cores: 4-(4-methylpentyloxy)phenyl-4-(decyloxy)benzoate [PhB1] and 4-(3-methylpentyloxy)phenyl-4-(decyloxy)benzoate [PhB2]. The mixture of the host LC, PhB1 or PhB2 with the chiral dopant, D-3,3′ or D-6,6′ shows chiral smectic LCs C (SC*-LCs). The highly twisted SC* phases with helical pitches of 1.2–1.4 μm are prepared in PhB1 and PhB2 by using the chiral dopant of D-6,6′. It is concluded that D-6,6′ has a large helical twisting power and is the most favourable atropisomeric chiral inducer for chirality transfer to both N-LCs and S-LCs.
Effects of final cooking temperature on the eating quality of pork loin steaks (1993)

Research conducted during the last few years shows that several factors affect the eating quality of pork and that it is possible to obtain good eating quality at low levels of fat in the carcass (ie. P2 ˂ 10mm). A Blueprint approach to meat quality improvement can be taken by combining appropriate genetic, nutritional, animal welfare and meat processing inputs. It is widely believed that care taken during cooking is important if the full benefit of the improved practices is to be realised. However there is little objective research on which to base recommendations. This study set out to examine the effects of cooking temperature on grilled loin steaks, a popular product although vulnerable to cooking abuse.
Flow Patterns of Liquid in a Cylindrical Mixing Vessel without Baffles (1959)

The velocity distribution of agitated liquid in a cylindrical mixing vessel was measured, using a set of pitot tubes, the composition of which is shown in Fig. 2. Some of the experimental results are shown in Figs. 4, 5, 6 and 8.As a result, the flow patterns in an agitated vessel were made clear and it was ascertained that, besides the primary circulation flow around the agitator axis, there was a secondary circulation of liquid caused by the discharging flow from the tip of the impeller as shown in Figs. 7 and 9. Integrating the measured velocity distributions, the discharging flow rates of the impellers were determined and the discharging performances of various impellers (Cf. Table 1) were compared, relative to the power consumption. Dimensionless factor, Nq1, defined by the author, was called the coefficient of discharge. The ratio, NP/Nq1 in Table 3, shows the relative power required for performing unit quantity of dis-charge.Furthermore, the power consumed in the neighbourhood of the impeller (NPimp), that is in the cylindrical domain (Cf. hatched region in Fig. 9), was calculated and compared with that consumed in the outer region of the vessel as shown in Table 4.From these considerations it is concluded that the improvement in the discharging capacity can be accomplished, to a certain extent, by a properly designed impeller, though we shall have to resort to some other devices for more fundamental improvements.
A simple on-line bin-packing algorithm (1985)

The one-dimensional on-line bin-packing problem is considered, A simple O (1)-space and O ( n )-time algorithm, called HARMONIC M , is presented. It is shown that this algorithm can achieve a worst-case performance ratio of less than 1.692, which is better than that of the O ( n )-space and O ( n log n )-time algorithm FIRST FIT. Also shown is that 1.691 … is a lower bound for all 0 (1)-space on-line bin-packing algorithms. Finally a revised version of HARMONIC M , an O ( n )-space and O ( n )- time algorithm, is presented and is shown to have a worst-case performance ratio of less than 1.636.
Computation of the distribution of the completion time when the work requirement is a ph random variableThis work was supported in part by the US Office of Naval Research under Contract no. N3014-88-K-0623, by NASA under Grant NAG-1-70, and by the Italian National Research Council CNR under the project “Material and Devices for Solid State Electronics” Grant no. 86.02177.61. (1990)

In this paper we derive the distribution of the completion time of a job with a PH-distributed work requirement, on a server modeled by a homogeneous Markov reward process. The interactions between the job in progress and the server are allowed to be either of resume or of repeat type in a probabilistic manner. The paper shows that the distribution of the completion time of a job with PH distributed requirement is PH under any mixture of preemptive policies. This result is stated as a closure property of the PH distribution class.
Stimulating spectrum of human recombinant multi-CSF (IL-3) on human marrow precursors: importance of accessory cells (1988)

Recently, human multi-CSF was obtained by molecular cloning. In the present study, the effects of multi-CSF in vitro were investigated by comparative culture of whole bone marrow or progenitor cells obtained by sorting the cell fraction that binds the monoclonal antibody (MoAb) B13C5 (CD 34). Multi-CSF stimulated erythroid (BFU-E), multipotential (CFU-GEMM) and eosinophil (CFU-Eo) colonies in cultures of the progenitor cell enriched fraction, whereas (besides BFU-E, CFU-GEMM, and CFU-Eo) granulocyte (CFU-G), granulocyte-macrophage (CFU-GM), and macrophage (CFU-M) colony-forming cells also were stimulated by multi- CSF when unfractionated bone marrow was cultured. Reconstitution of the progenitor cell fraction (B13C5 positive) with the B13C5-negative population restored the broad spectrum of progenitor cell stimulation. This suggested that accessory cells are required for expression of the full spectrum of progenitor cell stimulation by multi-CSF. Subsequently, specific marrow cell populations, including T lymphocytes, granulocytic cells, and monocytes, were prepared by using selected MoAbs in complement-mediated lysis or cell sorting, added to cultures of hematopoietic progenitors and tested for accessory cell function. The results demonstrate that small numbers of monocytes permit the stimulation of CFU-G, CFU-GM, and CFU-M by multi-CSF. These monocyte-dependent stimulating effects on CFU-G, CFU-GM, and CFU-M could also be achieved by adding recombinant GM-CSF as a substitute for monocytes to the cultures. Therefore, multi-CSF most likely has direct stimulative effects on BFU-E, CFU-GEMM, and CFU-Eo and indirect effects on CFU-G, CFU-GM, and CFU-M in the presence of monocytes.
Thieno[2,3-d]pyrimidine based derivatives as kinase inhibitors and anticancer agents (2015)

Thienopyrimidines are fused heterocyclic ring systems; structurally resemble purines, exerting pharmacological potential in different aspects. They are known to play a crucial role in various disease conditions. Thieno[2,3-d]pyrimidine derivatives have been explored for their inhibitory activities towards various protein kinase enzymes. The present review is a compilation on chemical synthesis and biological anticancer significance, via inhibition of specific protein kinase enzymes, including structure–activity relationships of thieno[2,3-d]pyrimidines derivatives reported to date.
LED Backlight Module by Lightguide-Diffusive Component (2012)

This study examines the luminance and uniformity characteristics of a newly invented secondary optical lens, called the “lightguide-diffusive component,” which has a wide emission angle and is designed for thin direct LED backlighting applications. The LED backlight module is composed of, at the very least, a light source, a secondary lightguide-diffusive component with a newly designed micro-structure having a reflective bottom surface, and a flexible printed circuit (FPC) for LED lighting. This lightguide-diffusive component modifies the emission profile of a single LED to provide better illumination and greater uniformity. The newly designed secondary optical lens module is shaped to cover the LED array, resulting in a more uniform spatial light energy distribution on the emission plane of the LED backlight. The uniformity ratio for the new design shows an increase of 24%, from 60% to 84%, and the luminance a 23.29% improvement, from 10 000 nits to 12 329 nits.
Correlation model for shadow fading in mobile radio systems (1991)

A simple autocorrelation model for shadow fading in mobile radio channels is proposed. The model is fitted to both large cells and microcells. Results show that the model fit is good for large to moderate cell sizes. It is however shown that the model does not provide adequate results for microcells.

Perovskite Oxide Nanosheets with Tunable Band‐Edge Potentials and High Photocatalytic Hydrogen‐Evolution Activity (2014)

Perovskite nanosheets of HCa(2-x)Sr(x)Nb3O10 and HCa2Nb(3-y)Ta(y)O10 with controlled band-edge potentials were prepared. They worked as highly efficient heterogeneous photocatalysts for H2 evolution from a water/methanol mixture under band-gap irradiation. The activity was found to depend on the composition. The highest activity was obtained with HCa2Nb2TaO10 nanosheets, recording an apparent quantum yield of approximately 80% at 300 nm, which is the highest value for a nanosheet-based photocatalyst reported to date.
High-Speed Photography In The Aeroballistic Range And Track Facilities Of The Von Karman Gas Dynamics Facility (1977)

A wide selection of instrumentation is used to provide photographic coverage of hypervelocity test models during flight in the aeroballistic range and track facilities of the von Karin.n Gas Dynamics Facility (VKF). Ultra high-speed framing camera techniques and front-light laser photographic systems are used to study interactions of in-flight test models and their flow fields with various erosive (dust, rain, snow, etc. ) environments. Front-light and back-light photographic systems employing xenon flash lamps as light sources are used for detailed characterization of the erosive fields. Photographic pyrometry systems featuring high-speed image intensifier devices provide measurements of surface temperatures of in-flight test models. Visible-light and x-ray shadowgraphs provide information describing the structural integrity of in-flight models and together with digital timing data comprise very accurate systems for measuring model velocity and aerodynamic coefficients. Finally, highly versatile schlieren systems provide photographic recording of detailed flow field information in black and white or in color. These high-speed photographic techniques are described briefly and several photographic examples are presented.
Bombesin and zinc enhance the synergistic mitogenic effects of insulin and phosphocholine by a MAP kinase‐dependent mechanism in Swiss 3T3 cells (1997)

Simultaneous treatment of serum-starved (24 h) Swiss 3T3 cells with insulin (500 nM) and phosphocholine (PCho) (0.25-1 mM) resulted in synergistic stimulation of DNA synthesis via a mitogen activated protein (MAP) kinase-independent rapamycin-sensitive mechanism. Co-treatment of cells with bombesin (10 nM) or zinc (25 microM) enhanced the combined mitogenic effects of insulin and PCho 2-3-fold; however, in the presence of bombesin or zinc the combined effects of insulin and PCho were not inhibited by rapamycin. The potentiating effects of bombesin and zinc on insulin plus PCho-induced DNA synthesis were accompanied by large stimulation of p42 MAP kinase activity. The results indicate that in Swiss 3T3 cell cultures, synergistic stimulation of DNA synthesis by extracellular insulin and PCho via a p42 MAP kinase-dependent mechanism requires the presence of other growth regulatory agents, such as bombesin or zinc.

Laboratory evaluation of kiln corrosion caused by the drying of wetwood (1983)

It is a long, commonly held view that kiln drying of certain species leads to excessive kiln corrosion. The corrosive effects of drying wood with high extractive concentrations and/or acidity on metallic parts has indeed been documented (2, 5, 6, 7, 8). The corrosive effect of western red cedar on steel and aluminum, in particular, has been shown to be due to the presence of tropolone extractives (3, 4). The drying of lumber containing wetwood is also generally believed to cause excessive kiln corrosion. As noted in the very comprehensive review by Ward and Pong (1980), wetwood is a type of heartwood in standing trees which has been internally infused with an excessively high moisture content. In addition to this difference in heartwood moisture content, wetwood also differs from normal wood in a number of other physical and mechanical properties, including the fact that it is more difficult to dry. The cause of wetwood formation is still not exactly understood but it has been attributed to bacterial infection, wound injury and/or normal age-growth formation. Wetwood is classified as being generally prevalent in western hemlock, and white, grand, and subalpine fir. It has scattered prevalence in other western coniferous species such as sugar and ponderosa pine, redwood, and western red cedar. Despite its wide occurrence in these varied softwood species, there is no actual data in the literature to either confirm or disprove the opinion that its drying actually does cause excessive corrosion. Excessive kiln corrosion is important for two reasons. The first and most obvious is that it can lead to shortened service life of the metal kiln structure and its various compounds thereby causing higher maintenance costs. Less apparent but perhaps even more important in the long run is that excessive corrosion very significantly affects the overall efficiency of the finned tube heating coils in the kiln. Lowered heat transfer rates mean increased steam consumption and greater overall heating or energy costs. For this reason, a cooperative project between the U.S. Forest Service Pacific Northwest Forest and Range Experiment Station and the University of California-Berkeley Forest Products Laboratory was set up with the purpose of: experimentally quantifying the corrosiveness of wetwood using white fir [Abies concolor (Gord and Glend)] as a reference species.
Apoprotein composition of very low density lipoproteins of human serum. (1975)

Methods for quantitation of the major apoproteins of human serum very low density lipoprotein have been developed employing tetramethylurea, which delipidates the lipoprotein and selectively precipitates apolipoprotein B. Six soluble apoproteins are separated by electrophoresis in polyacrylamide gel. One of these is a previously unrecognized species of R-alanine (R4-alanine), more anionic than the R3-alanine polypeptide. Conditions of staining have been found which yield reproducibly linear chromogenic response with native lipoprotein and with each purified apoprotein. Recovery of protein in the seven species measured accounts for over 97% of the total in the very low density lipoprotein of normolipidemic individuals and in most samples from individuals with endogenous hyperlipemia. The mean content of apolipoprotein B in 43 samples from normolipidemic subjects was 36.9(+/-1.2 SEM)% of total protein, The distribution of the major soluble apoproteins as mean (+/-SEM) percentage of the soluble fraction was : R-serine, 5.3+/-o.5; arginine-rich, 20.6+/-1.0; R-glutamic, 10.6+/-0.4; R2-alanine, 28.3+/-0.7; R3-alanine, 26.9+/-0.5; and R4-alanine, 8.0+/-0.5. Distribution of the apoproteins was a function of particle diameter of very low density lipoprotein in fractions separated by gel permeation chromatography and by density gradient ultracentrifugation. In fractions below 700-800 A, apolipoprotein B comprised an increasing percentage of the total protein with decreasing particle diameter. Among the soluble proteins the percentage of the arginine-rich and R-serine polypeptides increased and that of the R-glutamic polypeptide declined progressively with decreasing particle size. Apoprotein distribution was similar in fractions of similar particle size from normolipidemic and hyperlipemic subjects with the exception that all fractions from the hyperlipemic subjects contained more R-serine and some, more arginine rich polypeptide. Even in the absence of chylomicrons, the distribution of soluble apoproteins in particles of diameters greater than 700-800 A was usually similar to that of the smallest particles. This suggests that the largest particles may include products of the partial catabolism of chylomicrons.
Low Cost Dewatering of Waste Slurries (1993)

The U.S. Bureau of Mines has developed a technique for dewatering mineral waste slurries which utilizes polymer and a static screen. A variety of waste slurries from placer gold mines and crushed stone operations have been successfully treated using the system. Depending on the waste, a number of polymers have been used successfully with polymer costs ranging from $0.05 to $0.15 per 1,000 gal treated. The dewatering is accomplished using screens made from either ordinary window screen or wedge wire. The screens used are 8 ft wide and 8 ft long. The capacity of the screens varies from 3 to 7 gpm/sq. ft. The water produced is acceptable for recycling to the plant or for discharge to the environment. For example, a fine grain dolomite waste slurry produced from a crushed stone operation was dewatered from a nominal 2.5 pct solids to greater than 50 pct solids using $0.10 to $0.15 worth of polymer per 1,000 gal of slurry. The resulting waste water had a turbidity of less than 50 NTU and could be discharged or recycled. The paper describes field tests conducted using the polymer-screen dewatering system.
Endothelial cell migration and invasiveness are induced by a soluble factor produced by murine endothelioma cells transformed by polyoma virus middle T oncogene. (1993)

Polyoma virus middle T-transformed murine endothelioma cell lines provide a useful model for studying vascular lesions such as hemangiomas, hemangiosarcomas, and Kaposi's sarcoma and tumor-associated angiogenesis. In vivo they produce fast-growing, hemorrhaging, cavernous blood-filled hemangiomas, mainly formed by recruited host endothelial cells, suggesting an angiogenesis-like process underlying the lesion. The molecular mechanism(s) responsible for the recruitment of host endothelial cells by endothelioma cells has not yet been identified. We found that five different cultured endothelioma cell lines produced a soluble factor, named endothelioma-derived motility factor (EDMF) that stimulates chemotaxis (motility induced by a gradient of soluble attractant), haptotaxis (motility in response to substrate-bound attractant), and chemoinvasion (migration through a layer of reconstituted basement membrane, Matrigel) of normal human, bovine, and murine endothelial cells. The inhibitory effect of actinomycin D and of enzymatic treatment on its activity proved that EDMF is a protein. EDMF binds to heparin, since its activity was inhibited by heparin, and it was retained on a heparin-Sepharose column. Its molecular weight, as assessed by Sephacryl S-200 gel filtration, ranges from 40,000-65,000. Although in many aspects EDMF is similar to vascular permeability factor-vascular endothelial growth factor, this was not detected in endothelioma cell supernatants, as assessed by enzyme-linked immunosorbent assay, thus indicating that EDMF might be related to, but is not identical with, vascular permeability factor. Our findings support the notion that recruitment of host endothelial cells by endothelioma cells in vivo might be mediated by a still unidentified, soluble factor that stimulates and directs endothelial cell migration.
Jasper: Communicating Information Agents for WWW (1995)

This paper discusses a distributed system of intelligent agents for performing information tasks over the Internet World Wide Web (W3) on behalf of a user or community of users. We describe how agents are used to store, retrieve, summarize and inform other agents about information found on W3. Most current W3 clients (Mosaic, Netscape, and so on) provide some means of storing pages of interest to the user. Typically, this is done by allowing the user to create a (possibly hierarchical) menu of names associated with particular uniform resource locators (URLs). While useful, this quickly becomes unwieldy when a reasonably large number of W3 pages are involved. The solution we adopt to this problem is to allow the user to access information by a much richer set of metainformation than simply names assigned to particular URLs. Given the vast amount of information available on W3, it is preferable to avoid the copying of information from its original location to a local server. The local storage of only relevant metainformation also addresses this issue. The metainformation used includes automatically extracted keywords and summary, as well as the document title, URL and date and time of access. This metainformation is then used to index on the actual information when a retrieval request is made. When an agent stores a page, it will also automatically inform other users who it considers will be interested in the page's discovery via an email message. Thus Jasper is a small step towards automating the original vision for W3 as a network which supports cooperative working and the sharing of information. In addition, Jasper agents will modify a user's profile as the type of information the user is accessing changes. Pages stored in Jasper can be posted to interest groups, creating shared information resources about specific topics.
