Guidelines for firewall administrators regarding MIPv6 traffic (2011)

This document presents some recommendations for firewall
administrators to help them configure their existing firewalls in a
way that allows in certain deployment scenarios the Mobile IPv6
signaling and data messages to pass through. For other scenarios, the
support of additional mechanisms to create pinholes required for MIPv6
will be necessary. This document assumes that the firewalls in
question include some kind of stateful packet filtering capability.
Two new irregular acyclic sesquiterpenes aldehydes from Santolina corsica essential oil (2004)

Two isomeric irregular sesquiterpene aldehydes, namely 3,9-dimethyl-6-isopropyl-2(E),7(E),9-decatrienal and 3,9-dimethyl-6-isopropyl-2(Z),7(E),9-decatrienal, were isolated from the essential oil of Santolina corsica and their structures were elucidated by 1D and 2D NMR spectroscopy.
CdTe/CdS Clusters with “Core−Shell” Structure in Colloids and Films:  The Path of Formation and Thermal Breakup (2000)

A new organometallic “cold−slow” route to strongly fluorescing CdTe/CdS (core−shell) colloids and transparent films is presented. Based on the optical absorption, fluorescence, FTIR, micro-Raman, XPS, and XRD data collected on these nanostructures before and after thermal annealing, a mechanistic path of the core−shell formation and thermal break up is proposed and discussed. The processing of the CdTe/CdS nanostructures starts with 0.5 M tributylphosphine (TBP) stabilized CdS colloid in dichloromethane as a solvent. This yellow colloidal oil composed of 3−4 nm CdS clusters is reacted with liquid Bis(trimethylsilyl)-telluride (TMS2Te) in the presence of excess insoluble CdCl2 salt. During this reaction, a rapid chalcogen atom exchange occurs within a few seconds which produces a new CdTe “core”. The expelled sulfide reacts slowly with the CdCl2 salt to form new CdS clusters after several hours. Furthermore, this “CdS-formation-driven CdCl2 salt dissolution” activates a strong green-yellow fluorescence indicating a possible evolution of a “core−shell”-like CdTe/CdS structure. Thermal sintering of the subsequently prepared CdTe/CdS films between 100 and 200 °C completely suppresses the fluorescence and initiates CdTe cluster growth, reflecting a high thermal sensitivity of the “core−shell” interfaces. By further raising the sintering temperature to 300−400 °C, the TBP ligands are released and, consequently, bare CdS- and CdTe nanocrystals, as well as ternary nanocrystalline CdTexS1-x phases, start forming. Above 400 °C, the CdTe part of the nanostructures sublimates, yielding (111)-oriented CdTe films.

Modelling anaerobic codigestion of manure with olive oil mill effluent (1997)

A mathematical model describing the combined anaerobic degradation of complex organic material, such as manure, and a lipid containing additive, such as olive oil mill effluents, has been developed based on a model previously described (Angelidaki et al. 1993). The model has been used to simulate anaerobic codigestion of cattle manure together with olive oil mill effluent (OME) and the simulations were compared with experimental data. Simulation data indicated that lack of ammonia, needed as nitrogen source for synthesis of bacterial biomass and as an important pH buffer, could be responsible for the problems encountered when anaerobic degradation of OME alone is attempted. It was shown that the amount of nitrogen needed to obtain a stable degradation of OME can be provided by manure during codigestion of OME and manure.
Biologic Stress, Oxidative Stress, and Resistance to Drugs: What Is Hidden Behind (2017)

Stress can be defined as the homeostatic, nonspecific defensive response of the organism to challenges. It is expressed by morphological, biochemical, and functional changes. In this review, we present biological and oxidative stress, as well as their interrelation. In addition to the mediation in biologic stress (central nervous, immune, and hormonal systems) and oxidative stress, the effect of these phenomena on xenobiotic metabolism and drug response is also examined. It is concluded that stress decreases drug response, a result which seems to be mainly attributed to the induction of hepatic drug metabolizing enzymes. A number of mechanisms are presented. Structure-activity studies are also discussed. Vitamin E, as well as two synthetic novel compounds, seem to reduce both oxidative and biological stress and, consequently, influence drug response and metabolism.
Application of Metrizamide in the Radiographic Evaluation of the Neurologically Diseased Patient (1979)

Metrizamide (Amipaque) is a new water-soluble contrast agent for use in the intrathecal space. Extensive animal and clinical studies have demonstrated its low toxicity. The advantages to the use of metrizamide include the fact that it is miscible with cerebrospinal fluid and can fill narrow spaces, is sufficiently radiopaque to outline delicate structures within the central nervous system, is completely resorbed from the subarachnoid space, and, to date, has not been implicated in the formation of adhesive arachnoiditis. Application of metrizamide to the evaluation of neurologically diseased patients has included myelography, intracranial cisternography, and ventriculography, as well as various techniques in conjunction with computerized tomography. These various uses of metrizamide are discussed together with some indications and advantages. Metrizamide has now replaced Pantopaque and gas as the most commonly used intrathecal contrast agent at the University of Texas Health Science Center at Dallas.
An efficient spectral method for ordinary differential equations with rational function coefficients (1996)

We present some relations that allow the efficient approximate inversion of linear differential operators with rational function coefficients. We employ expansions in terms of a large class of orthogonal polynomial families, including all the classical orthogonal polynomials. These families obey a simple 3-term recurrence relation for differentiation, which implies that on an appropriately restricted domain the differentiation operator has a unique banded inverse. The inverse is an integration operator for the family, and it is simply the tridiagonal coefficient matrix for the recurrence. Since in these families convolution operators (i.e., matrix representations of multiplication by a function) are banded for polynomials, we are able to obtain a banded representation for linear differential operators with rational coefficients. This leads to a method of solution of initial or boundary value problems that, besides having an operation count that scales linearly with the order of truncation <inline-formula content-type="math/mathml"> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="upper N"> <mml:semantics> <mml:mi>N</mml:mi> <mml:annotation encoding="application/x-tex">N</mml:annotation> </mml:semantics> </mml:math> </inline-formula>, is computationally well conditioned. Among the applications considered is the use of rational maps for the resolution of sharp interior layers.
Dependence of fluorescence lifetime in praseodymium-doped silica optical fibres upon strain and temperature (2009)

Measurements of the temperature and strain responses of fluorescence lifetimes for two transitions in praseodymium-doped silica optical fibres are presented. These properties were found to be similar to those measured for other rare-earth-doped fibres, except for the strain response. In particular, the fluorescence lifetime of the ,3H6 transition (centred on 870 nm) exhibited a slight decrease with applied strain, rather than an increase. This has implications for our understanding of how strain in rare-earth-doped optical fibres affects fluorescence properties.

Thermally induced color change in electrospun fiber mats (2004)

Abstract Electrospinning is a process that employs a high static electrical potential to produce polymeric fibers of nanoscale diameter. The process has been utilized to achieve color change by electrospinning black polymer solutions to produce white fiber mats. When subsequently heated, the electrospun mats undergo a color change from white to black. This phenomenon is demonstrated with three polymer/solvent systems. © 2004 Wiley Periodicals, Inc.

Workflow Interdependence Analysis of Projects in Business Ecosystems (2019)

This article contributes to engineering project research by studying how projects relate to their surrounding context. The article presents a framework for the analysis of workflow interdependencies in a project that is situated in a business ecosystem. The analysis is used to reduce costly conflicts in the business ecosystem, and the framework shows how the project is positively impacted by the resolution of those conflicts. The framework elaborates James Thompson’s notion of pooled, sequential and reciprocal interdependence and distinguishes between compatible-reciprocal and contentious-reciprocal interdependencies. The relationship between interdependence types and their corresponding coordination and governance mechanisms, originally posited for interdependence between tasks and groups within a single organization, applies equally well to interdependence types and governance mechanisms across firm boundaries within a business ecosystem. We analyze a cargo vessel development project within the short sea logistics business ecosystem to illustrate how the proposed framework can remove unproductive workflow conflicts and enhance value creation.
General Approach for the Synthesis of Nitrogen-Doped Carbon Encapsulated Mo and W Phosphide Nanostructures for Electrocatalytic Hydrogen Evolution (2020)

A general strategy for the synthesis of the core-shell nanostructure of nitrogen-doped carbon encapsulated MoP and WP (MoP@NC and WP@NC) and the electrochemical hydrogen evolution reaction (HER) are demonstrated. The synthetic procedure involves the self-assembling of polyoxometalate (M = Mo/W) and phytic acid on a polyetheleneimine backbone and the subsequent pyrolysis of the self-assembled supramolecular aggregates in an inert atmosphere without a traditional phosphidating agent. MoP@NC has a quasi-spherical shape with a MoP core (57 nm) and nitrogen doped porous carbon shell, whereas WP@NC has a nitrogen-doped carbon coated rodlike nanostructure. MoP@NC has a large amount of pyridinic (∼59%) and Mo-bonded (∼33%) nitrogen. MoP@NC is highly active toward hydrogen evolution reaction (HER) and delivers the benchmark current density 10 mA/cm2 at an overpotential of 52, 106, and 171 mV in acidic, alkaline and neutral pH, respectively. It shows a Tafel slope of 49 mV/dec, high turnover frequency (0.28 s–1 at η = 100 mV), and faradaic efficiency (96%) in acidic electrolyte. MoP@NC has remarkable durability in acidic and alkaline pH with a negligible increase in overpotential after 1000 extensive repeated potential cycles. The encapsulating nitrogen-doped carbon shell protects the active catalyst from corrosion and the catalyst retains its phase purity and structural integrity even after 10 h of long-time hydrogen evolution at constant potential. The outstanding HER activity of MoP@NC is accounted for by the small particle size, large surface area, and strong chemical coupling between MoP and nitrogen-doped carbon.
Antiproliferative effect of retinoid compounds on Kaposi's sarcoma cells. (1994)

A panel of retinoid compounds (tretinoin, isotretinoin, acitretin, and RO13-1470) were tested for inhibitory activity against Kaposi's sarcoma cell (KSC) cultures in vitro. Tretinoin was found to be the most effective retinoid tested, inhibiting the growth of KSC in vitro while having no effect on the expression of interleukin-6 and basic fibroblast growth factor, two important cytokines involved in KSC growth. Tretinoin also did not appear to downregulate the expression of receptors for these two cytokines. At low concentrations (10(-9) M), acitretin and tretinoin selectively inhibited growth of early passage KSC. At higher concentrations (10(-6)-10(-5) M), retinoid treatment induced a pattern of DNA degradation and morphological changes in KSC characteristic of apoptosis (programmed cell death). The inhibitory activity of tretinoin on KSC growth was decreased if human serum (but not fetal calf serum) was present in the growth medium, and partially restored by removal of serum lipids. These data suggest that retinoids possess potential as therapeutic agents in Kaposi's sarcoma.
[Economic profitability: current aspects of X-ray contrast diagnosis in urology]. (2006)

A diversity of X-ray contrast diagnostic techniques used in urology provides a way of using different groups of X-ray contrast materials (XCMs) in accordance of the set tasks. Many years' experience in handling water-soluble triiodinated XCMs while examining the kidneys and urinary tract provides evidence for their diagnostic effectiveness and safety. The new Triombrast (OAO "Farmac", Kiev) synthesized on the basis of the Spanish substance (Justesa Imagen SA) has successfully undergone clinical trials and meets the high requirements made by the specialized urological facilities is economically profitable. The paper has been prepared, by using the reports on the results of preclinical studies of the agent and the experience of its use in the clinic of the Research Institute of Urology and City Clinical Hospital No. 47, Moscow.
Metal−Ligand Cooperativity in O2 Activation: Observation of a “Pt−O−O−C” Peroxo Intermediate (2010)

The Pt(IV) complex (tBuMe2nacnac)PtMe3 (1, tBuMe2nacnac = [((4-tBu-2,6-Me2C6H2)NC(CH3))2CH]) reacts with molecular oxygen to form a peroxo complex, 2, in which one oxygen atom is bound to the platinum center and the other to the central carbon of the nacnac ligand backbone. Over time, 2 converts to a new Pt(IV) species (3) wherein the oxygen−oxygen bond has been cleaved.
Microseguros : una estrategia para la gestion de riesgos (2003)

Over two billion people worldwide lack any type of formal social security protection. Poor people are the least likely to benefit from coverage, yet they are the most vulnerable to risk and economic stress. Responding to this situation requires the involvement of a range of actors. Currently in the spotlight, micro-insurance is one of many financial services that helps manage risk. Micro-insurance is the protection of low-income people against specific perils in exchange for regular monetary payments (premiums) proportionate to the likelihood and cost of the risk involved. As with all insurance, risk pooling allows many individuals or groups to share the costs of a risky event. To serve poor people, micro-insurance must respond to their priority needs for risk protection (depending on the market, they may seek health, car, or life insurance), be easy to understand, and affordable. This report covers the dos and don'ts of micro-insurance for donors.
Chicken ovalbumin is synthesized and secreted by Escherichia coli. (1978)

By recombinant DNA methods, the chicken ovalbumin structural gene has been fused to Escherichia coli lac transcriptional and translational control regions. When a plasmid containing the hybrid gene was introduced into E. coli, a protein identified as ovalbumin by immunoreactivity and sodium dodecyl sulfate/polyacrylamide gel electrophoresis was synthesized. The chicken ovalbumin made in bacteria was full length (43,000 daltons) and constituted 1.5% of the cellular protein. In addition, the microbially synthesized ovalbumin was secreted through the cell membrane into the periplasmic space of E. coli. The ability of the E. coli secretory apparatus to recognize chicken ovalbumin, which is normally synthesized and secreted in hen oviducts, suggests that common features exist in the secretion-recognition mechanisms found in these two organisms. The bacterial synthesis of significant amounts of chicken ovalbumin demonstrates that the E. coli cellular machinery may be utilized to synthesize a higher eukaryotic protein which is relatively stable in the bacterial intracellular environment.
Proteomic profile of Piper tuberculatum (Piperaceae) (2017)

Piper tuberculatum (Piperaceae) is a species that accumulates especially amides as secondary metabolites and several biological activities was previously reported. In this article, we report a proteomic study of P. tuberculatum. Bidimensional electrophoresis (2D SDS-PAGE) and mass spectrometry (ESI-Q-TOF) were used in this study. Over a hundred spots and various peptides were identified in this species and the putative functions of these peptides related to defense mechanism as biotic and abiotic stress were assigned. The information presented extend the range of molecular information of P. tuberculatum.
HEAT TRANSFER IN MICROCHANNELS (2023)

In this paper an attempt has been made to review the literature regarding heat transfer and pressure drop in one- and two-phase flow in microchannels. The emphasis has been on reports presented during the last few years. For single phase flow, channels with hydraulic diameters less than 1 mm have been considered. In two-phase flow very little information is available for such small channels. Also, for two-phase flow, deviations from large-tube behavior start at diameters of a few millimeters. For these reasons a slightly larger diameter range has been considered in this case.<br> As a conclusion it could be stated that the understanding of flow in microchannels is increasing steadily, but that there are still many questions to be answered concerning the reasons for deviations from classical theory developed for larger channels.
Helium-Based Simulation of Smoke Spread Due to Fire in Enclosed Spaces (1997)

This study concerns helium smoke simulators which have been used for simulating smoke spread in aircraft cabins during inflight tests. The smoke from cabin fires is buoyant due to higher temperatures, compared to the surroundings. However, the smoke from commercially available smoke generators is nonbuoyant and an addition of helium is employed to make it buoyant so that the actual circumstance is closely represented. The dependence of buoyancy on the concentration of helium and Ihe validity of this approach to represent thermal buoyancy effects are important questions that need to be answered. In this technique, helium is added to smoke from commercially available smoke generators in order to provide buoyancy in the flow due to the lower density of helium. The mixture is then used to simulate the flow of smoke and toxic gases in the cabin of an aircraft, or in other enclosed spaces, without employing heated air to obtain the buoyancy. Since buoyancy plays a very important role in the flow and spread of smoke and hot gases, it is important that the simulation include this effect in order to closely represent the actual flow An experimental investigation is undertaken to explore the validity of simulating thermally buoyant gases, from a fire, wilh a helium and air mixture. The experimental flow consisted of a ceiling jet with a corner flow. This same configuration was used in previous studies which were directed at thermally buoyant flows. Thus, a basis for comparison between the two buoyant flows can be established. Parameters, such as the volume flow rate of the air and helium and the initial helium concentration, were varied over wide ranges. Temperature profiles from the thermally buoyant case were compared to helium concentration profiles. In addition, velocity profiles from the two studies were compared to determine the flow spread. From these results, the characteristics of the buoyant helium-air mixture were obtained. It is found that, though this mixture can be used to qualitatively model thermally buoyant flows, large quantitative differences exist between the two and must be taken into account for an accurate simulation.
Morphologic and Ultrastructural Changes (1987)

The vascular endothelium plays an important and complex role in vascular allograft rejection. Antigens expressed by the endothelium can act to promote and be the target of rejection reactions, which often lead to thrombosis and ischemic necrosis of the allograft. In this study, segments of femoral artery and femoral vein with or without endothelium were grafted between allogenic or autologous control rats. Immunocompetent Lewis (RT1(1] recipient rats were randomly selected for groups (N = 14 for each) receiving the following: ACI- (RT1a) allografts with intact endothelium, allografts with endothelium removed before operation, autografts with endothelium, and autografts with endothelium removed. Rejection was assessed by graft patency as well as morphologic and ultrastructural changes. At 5 days, the allografts with intact endothelium were totally occluded, whereas allografts without endothelium remained patent, as did autologous control grafts with or without endothelium. Two additional groups (N = 14 each) receiving the de-endothelialized allografts or autografts were examined at 120 days after operation, revealing that grafts in both groups were still patent and had been re-endothelialized. These findings indicate that physical removal of vascular endothelium may depress vessel allograft rejection without immunosuppressive therapy.
A New CPW-Fed Circularly Polarized Square Slot Antenna Design (2017)

In this work, a new wideband circularly polarized square slot antenna (CPSSA) with a coplanar waveguide (CPW) feed is proposed. The suggested antenna is wrought of one arc-shaped, two inverted-L grounded strips around, two opposite corners of the square slot and C shaped(smile) gap on the patch. In this outline the impedance bandwidth and the axial ratio bandwidth (ARBW) are increased compared to the previous CPSSA designs. In this way, the 3 dB axial ratio bandwidth of the designed antenna improved and reached to more than 57 % (3.2 GHz - 5.7 GHz) and the VSWR (Voltage Standing Wave Ratio) &amp;amp;lt; 2 impedance bandwidth increased as large as 108 % (3 GHz - 10.1 GHz). Overall this work, the optimized method of the axial ratio (AR) and S11are provided and discussed in text. The fabricated antenna results agree well with the simulation analysis.
