A New Flavonoid from Selaginella tamariscina (Beauv.) Spring (2010)

A new flavonoid, 6-(2-hydroxy-5-carboxyphenyl)-apigenin (1), together with two new natural products, 3-(4-hydroxyphenyl)-6,7-dihydroxy coumarin (2), 1-methoxy-3-methylanthraquinone (3) and four known compounds, were isolated from Selaginella tamariscina (BEAUV.) SPRING. The structures of the new isolated compounds were elucidated on the basis of 1D and 2D NMR as well as ESI-HR-MS spectroscopic analysis.
Communication processors (1972)

A review is given of the use of small digital computers for the processing of data received over communication lines. A detailed discussion is presented of the hardware and software requirements of front-end processors, network processors, remote data concentrators, and message switching systems. Finally, the desirable features common to all communications processors are analyzed. Examples of actual applications are given, so that a realistic basis can be established for the determination of the features which should be included in the design of new communication processors.
New AC-based capacitance tomographysystem (1999)

Electrical capacitance tomography (ECT) is a new technology that is used to visualise the internal behaviour of industrial processes comprising dielectric components. A particular difficulty with capacitance measurement for tomography is that the stray capacitance to earth of an ECT sensor is large (~150 pF) compared with the interelectrode capacitance to be measured (usually <0.5 pF), and the measurement range is wide (0.01–2 pF). The authors present a highly sensitive AC-based capacitance measuring circuit, which has been specially designed for this purpose, and a PC-based ECT system with this circuit. Experimental results show that this ECT system can measure as small as 0.01 pF capacitance with 0.0002 pF error, and could collect tomographic image data at more than 100 frames per second.
Innervation of the conjunctiva. (1985)

A parasympathetic pathway from the facial nerve to the conjunctiva was confirmed. Many conjunctival nerve fibres were degenerated following pterygopalatine ganglion lesion in cynomolgus monkeys. Nerve terminal degeneration was found mainly in the large vessel walls and adjacent to the subepithelial capillaries. AChE positive nerve fibres of undenervated tissue, probably representing the cholinergic fibres of facial nerve origin, and sympathetic nerve terminals, identified by their small granular vesicle content, were similarly disposed in vessel walls. Hence conjunctival vessels, including capillaries, have a dual autonomic innervation. Intraepithelial terminals were sparse and no evidence of a specific goblet cell innervation was found. Human perilimbal conjunctiva displayed a similar distribution of nerve fibres to cynomolgus monkeys.

TLR4 Protein Contributes to Cigarette Smoke-induced Matrix Metalloproteinase-1 (MMP-1) Expression in Chronic Obstructive Pulmonary Disease (2011)

Cigarette smoke is the major risk factor associated with the development of chronic obstructive pulmonary disease and alters expression of proteolytic enzymes that contribute to disease pathology. Previously, we reported that smoke exposure leads to the induction of matrix metalloproteinase-1 (MMP-1) through the activation of ERK1/2, which is critical to the development of emphysema. To date, the upstream signaling pathway by which cigarette smoke induces MMP-1 expression has been undefined. This study demonstrates that cigarette smoke mediates MMP-1 expression via activation of the TLR4 signaling cascade. In vitro cell culture studies demonstrated that cigarette smoke-induced MMP-1 was regulated by TLR4 via MyD88/IRAK1. Blockade of TLR4 or inhibition of IRAK1 prevented cigarette smoke induction of MMP-1. Mice exposed to acute levels of cigarette smoke exhibited increased TLR4 expression. To further confirm the in vivo relevance of this signaling pathway, rabbits exposed to acute cigarette smoke were found to have elevated TLR4 signaling and subsequent MMP-1 expression. Additionally, lungs from smokers exhibited elevated TLR4 and MMP-1 levels. Therefore, our data indicate that TLR4 signaling, through MyD88 and IRAK1, plays a predominant role in MMP-1 induction by cigarette smoke. The identification of the TLR4 pathway as a regulator of smoke-induced protease production presents a series of novel targets for future therapy in chronic obstructive pulmonary disease.
High-dose intracavitary cisplatin with intravenous thiosulfate. Low incidence of serious neurotoxicity (1985)

Recent published reports have suggested that cisplatin administered in high doses or in certain combination chemotherapy can cause serious neurotoxicity in a large percentage of patients treated. In several high-dose cisplatin-based intracavitary chemotherapy trials with the simultaneous intravenous administration of sodium thiosulfate, the incidence of clinically relevant neurotoxicity has been extremely low. In addition, several patients with serious preexisting cisplatin-induced neurologic dysfunction were treated without worsening of their clinical condition. It is suggested that thiosulfate might have been responsible for the low incidence of neurotoxicity in this patient population. Further experimental and clinical investigation of the potential of this agent to protect against cisplatin-induced neuropathy appears warranted.
Central-Airway Necrosis after Stereotactic Body-Radiation Therapy (2012)

Stereotactic body-radiation therapy is a novel technique that aims to deliver higher doses of radiation to cancers in a more focused way. However, adjacent tissues also get higher doses and fatal toxicities can emerge, as in one patient.
Review of methodologies for the determination of nonvolatile<i>N</i>‐nitroso compounds in foods (1987)

An attempt has been made to briefly review methods available for the determination of total N-nitroso compounds, N-nitrosamides, N-nitrosamino acids, and miscellaneous other nonvolatile N-nitroso compounds in foods and beverages, giving special emphasis to the progress made during the past five years. It appears that a wide variety of acceptable methods are available for N-nitrosamino acids and simple hydroxylated N-nitrosamines, but none of them has yet been adequately validated. Only limited progress has been made for the analysis of N-nitrosamides, N-nitroso sugar amino acids, and other N-nitroso compounds. Various mass spectrometric methods available for the determination and confirmation of these compounds are also discussed.
Point and Counterpoint (1991)

This article conceptualizes a model of duality, a continuous parallel process between oncology patients and their caregivers. The central shared themes-feelings of difference, survivor's guilt, uncertainty, loss of control, and existential pain-are explored in a context of reflection and preparation for survivorship. Understanding the strong affect that is an intrinsic part of the cancer experience for both patients and caregivers is normalizing and enables all involved to function in growth-enhancing ways. The rcsulting healthy self-awareness empowers caregivers to help themselves and their patients to manage life successfully through and beyond cancer.
Structure of β-Glucan Oligomer from Laminarin and Its Effect on Human Monocytes to Inhibit the Proliferation of U937 Cells (2005)

We analyzed the human monocyte-stimulating ability of laminarin from Eisenia bicyclis, lichenan from Cetraria islandica, and their oligomers depolymerized with endo-1,3-beta-glucanase from Arthrobacter sp. The respective beta-glucan oligomers with different degrees of polymerization (DP) were fractionated from hydrolytic products of laminarin and lichenan using gel-filtration chromatography. The monocyte-conditioned medium pre-cultured in the presence of a fraction of beta-glucan oligomer (DP>/=8) from laminarin exhibited inhibitory activity against the proliferation of human myeloid leukemia U937 cells, while those pre-cultured with other beta-glucan oligomers and the original laminarin and lichenan showed little or no activity. NMR analysis indicated that the beta-glucan oligomer (DP>/=8) has an average DP value of 13, and its ratio of beta-1,3- to beta-1,6-linkages in glucopyranose units was estimated to be 1.3:1. These results indicate that the beta-1,3-glucan oligomer with a higher content of beta-1,6-linkage stimulates monocytes to inhibit the proliferation of U937 cells.
Thermoluminescence, photoluminescence and optically stimulated luminescence properties of X‐ray irradiated RbMgF<sub>3</sub>:Mn<sup>2+</sup> (2007)

Abstract Optically stimulated luminescence (OSL) is observed after x‐ray irradiation in Mn 2+ doped RbMgF 3 polycrystalline samples over a wide wavelength range in the near UV and with a stimulation maximum near 350 nm. The OSL emission occurs by relaxation from the first excited state to the ground state of Mn 2+ . It is possible that one of the electron traps can be attributed to an F ‐center. However, thermoluminescence (TL) measurements show that there are at least 5 defect centers in this compound. Sintered polycrystalline samples have a higher OSL intensity when compared with the as‐made samples. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Fragancias de tres especies de orquídeas de la región del Soconusco, Chiapas, México y su relación con la polinización (2003)

The study provided preliminary support for the construct validity and reliability of the MHLq-SVa as a measure for assessing MHL in young adults from six different countries and languages. Future studies are needed to further validate the measure and undertake multicultural comparisons of MHL in diverse samples from around the globe.
Standard and variant CD44 isoforms are commonly expressed in lung cancer of the non‐small cell type but not of the small cell type (1995)

Cluster of differentiation 44 (CD44) encompasses a polymorphic family of cell membrane glycoproteins involved in the mechanism of tumour invasion and metastasis. Since non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) display very different rates of progression, a significant discrepancy in their CD44 expression profiles is to be expected. An immunohistochemical study was undertaken on the expression of standard CD44 (CD44s) and the variant isoforms containing the domains encoded by variant exon 3 (CD44v3) or variant exon 6 (CD44v6) in paraffin-embedded bronchial biopsy specimens from 32 NSCLC cases and 11 SCLC cases. An absolute lack of immunoreactivity for CD44s, CD44v3, and CD44v6 was obtained in every case of SCLC, whereas 28 of the 32 NSCLC cases showed a positive immunoreaction for at least one of the three epitopes investigated. In conclusion, the occurrence of standard and variant CD44 isoforms in NSCLC and their absence in SCLC suggest the possibility that CD44 is in some way instrumental in conditioning the biological behaviour of NSCLC, but not of SCLC, whose metastatic cascade would be set in motion by the activation of hitherto unidentified, CD44-independent pathways.
Analyzing the Use of Wilderness (1974)

Increasing demand for low-density or wilderness recrea tion has caused the problems of management and alloca tion of undeveloped public lands to become an important problem. This paper describes a large-scale traffic- simulation model developed to evaluate the implications of alternative management strategies for the quality of the recreational services provided by wilderness areas. The model is capable of simulating recreational patterns in real-world systems and has been applied to the Spanish Peaks Primitive Area in Montana.
Corrosion, its Causes, Cost and Prevention: A Brief History of the Growth of Corrosion Study (1957)

The phenomenon of metallic corrosion was recognised in ancient times and, although a considerable amount of work has now been done in this field, especially during the last few decades, the complete mechanism is by no means understood.
What Is the Appropriate Management of Tissue Extravasation by Antitumor Agents? (1985)

Review of 175 patients sustaining extravasation of an antitumor agent showed that most (89 percent) can be managed immediately with intermittent application of ice (15 minutes four times daily for 3 days) and close wound observation. We consider pain, usually associated with varying degrees of skin involvement, to be the only indication for surgery. Such a procedure should consist of wide, three-dimensional excision of all involved tissue, temporary coverage with a biologic dressing, and simultaneous harvesting and storage of a split-thickness skin graft. Once the wound is clean, delayed application of the graft is performed (usually at 2 to 3 days). Not only will this result in immediate pain relief and provide safe wound coverage, but it also will not interrupt the patient's chemotherapy schedule. Most patients were able to be restarted on their chemotherapy shortly after surgery, and none demonstrated a "recall phenomenon."
An experiment on the Rayleigh instability of charged liquid drops (2007)

We describe a simple experiment to observe the fission of an electrically charged liquid droplet. Rayleigh charge instability occurs when the electrostatic repulsion of charges on the surface of a droplet overcomes the droplet surface tension and tears the droplet apart. The experiment requires a low-power laser, simple optics, a CCD camera, and a quadrupole trap, which can be constructed using widely available and relatively straightforward instructions. The experiment was performed primarily by undergraduates as part of their senior research projects and can be implemented readily in an advanced undergraduate physics laboratory course.
Focusing of high-current, large-area, heavy-ion beams with an electrostatic plasma lens (1999)

We report on measurements of the focusing of high-current, large-area beams of heavy metal ions using an electrostatic plasma lens. Tantalum ion beams were formed by a repetitively pulsed vacuum arc ion source, with energy in the 100 keV range, current up to 0.5 A, initial beam diameter 10 cm, and pulse length 250 μs. The plasma lens was of internal diameter 10 cm and length 20 cm, and had nine electrostatic ring electrodes with potential applied to the central electrode of up to 7 kV, in the presence of a pulsed magnetic field of up to 800 G. The current-density profile of the downstream, focused, ion beam was measured with a radially moveable, magnetically suppressed, Faraday cup. The tantalum ion-beam current density at the focus was compressed by a factor of up to 30. The results are important in that they provide a demonstration of a means of manipulating high-current ion beams without associated space-charge blowup.
Autonomous Exploring Map and Navigation for an Agricultural Robot (2020)

In this paper, the robot is exploring and creating a map of the environment for autonomous navigation. Exploration forms an important role in creating the map and locating the obstacles for path planning. Autonomous Frontier Based Exploration is implemented on both hardware and software of the Turtlebot3 Burger platform. For Simultaneous Localization and Mapping (SLAM), the Breadth-First Search (BFS) algorithm is used. The path planning uses the A * algorithm for the global planning and for local planning uses the Dynamic Window Approach (DWA). The software used in this work is Ubuntu 18.04, along with ROS Melodic on virtual box. This is a work in progress, and the results will be used in further research work for autonomous monitoring of the agricultural fields.
SOME ENGINEERING PROPERTIES OF DIFFERENT FEED PELLETS (2011)

Due to lack of information about the physical and mechanical properties of feed pellets which are very important to understand the behavior of the product during the processing operations such as transporting, packaging and storage processes and also, it is necessary in processing operations. The main objective of this work was to study the physical and mechanical properties to form an important database for four of the most popular feed pellets in Egypt. These properties include: linear dimensions, mean diameter, surface area, volume, mass, density, static friction coefficient, repose angle and crushing load. The engineering parameters results showed that the length and mean diameters were in the range of 0.50-2.44 and 0.40-1.24 cm for all pellet sizes with CV of 12-33 and 2-3 %. Feed pellet types in all sizes were cylindrical in shape. The surface areas ranged from 0.86-11.95 cm2 and the feed pellet mass ranged from 0.07-3.01 g depending on the feed pellet size. The volume ranged from 0.06-2.96 cm3 with CV of 11-31%, the bulk density ranged from 0.64-0.74 g/cm3 with CV of 23-36% and real density ranged from 1.02-1.15 g/cm3 with CV of 9-14% for all feeds. The repose angle ranged from 25.67-38.7o. The coefficient of static friction (C.S.F) ranged from 0.48-0.80 for all sizes and surfaces. The highest C.S.F was offered by concrete surface followed by the plywood and the galvanized steel surfaces. Crushing load increased with the pellet size ranged from 90.74 to 454.13 and from 29.5 to 348.35 N in vertical and horizontal position, respectively, depending on the feed pellet size.

A novel class of clathrin-coated vesicles budding from endosomes. (1996)

Clathrin-coated vesicles transport selective integral membrane proteins from the plasma membrane to endosomes and from the TGN to endosomes. Recycling of proteins from endosomes to the plasma membrane occurs via unidentified vesicles. To study this pathway, we used a novel technique that allows for the immunoelectron microscopic examination of transferrin receptor-containing endosomes in nonsectioned cells. Endosomes were identified as separate discontinuous tubular-vesicular entities. Each endosome was decorated, mainly on the tubules, with many clathrin-coated buds. Endosome-associated clathrin-coated buds were discerned from plasma membrane-derived clathrin-coated vesicles by three criteria: size (60 nm and 100 nm, respectively), continuity with endosomes, and the lack of labeling for alpha-adaptin. They were also distinguished from TGN-derived clathrin-coated vesicles by their location at the periphery of the cell, size, and the lack of labeling for gamma-adaptin. In the presence of brefeldin A, a large continuous endosomal network was formed. Transferrin receptor recycling as well as the formation of clathrin-coated pits at endosomes was inhibited in the presence of brefeldin A. Together with the localization of transferrin receptors at endosome-associated buds, this indicates that a novel class of clathrin-coated vesicles serves an exit pathway from endosomes. The target organelles for endosome-derived clathrin-coated vesicles remain, however, to be identified.
DVB-S2 Technology Development for DoD IP SATCOM (2006)

The Defense Information System Agency has awarded a contract, under The Office of the Secretary of Defense's Defense Acquisition Challenge Program, to demonstrate the bandwidth savings that can be achieved for the global broadcast service by using the DVB-S2 waveform. Under this effort, specialized DVB-S2 transmitter and receiver equipment will be developed to include the capability to operate in the variable coding and modulation mode for one-way broadcast systems. This will conclude with a live demonstration of the technology over Military Satellite and Commercial Satellite Communication assets. The demonstration will show how the DVB-S2 waveform allows for optimization of the broadcast to support simultaneous transmission of information to specific terminal sets with different aperture sizes, including severely disadvantaged terminals. This paper will deliver the results of this demonstration and compare it to the theoretical analysis. Concepts and techniques needed for performing single carrier, multi-code link analysis will be described. In addition this paper will discuss the advantages of the advanced coding and modulation mode for two-way systems and its implementation challenges into the next generation joint IP modem architecture
Solubility Measurements in the System CaSO4-NaCl-H2O at 35 , 50 , and 70 Cand one atmosphere Pressure (1965)

The solubilities in the system CaSO 4 –NaCl–H 2 O, at 1 atm pressure and 35°, 50°, and 70°C, have been determined by approaching the solubility curves from both the undersaturation and supersaturation sides. The experimental runs are of long duration, as much as 3 months; these rates should be commensurate with those of the appropriate geological processes, and so the results should be directly applicable to the interpretation of evaporite deposits.
