Preparation, Characterization, and Performance Evaluation of Polysulfone Hollow Fiber Membrane with PEBAX or PDMS Coating for Oxygen Enhancement Process (2018)

Air pollution is a widely discussed topic amongst the academic and industrial spheres as it can bring adverse effects to human health and economic loss. As humans spend most of their time at the office and at home, good indoor air quality with enriched oxygen concentration is particularly important. In this study, polysulfone (PSF) hollow fiber membranes fabricated by dry-jet wet phase inversion method were coated by a layer of polydimethylsiloxane (PDMS) or poly(ether block amide) (PEBAX) at different concentrations and used to evaluate their performance in gas separation for oxygen enrichment. The surface-coated membranes were characterized using SEM and EDX to determine the coating layer thickness and surface chemical properties, respectively. Results from the gas permeation study revealed that the PSF membrane coated with PDMS offered higher permeance and selectivity compared to the membrane coated with PEBAX. The best performing PDMS-coated membrane demonstrated oxygen and nitrogen gas permeance of 18.31 and 4.01 GPU, respectively with oxygen/nitrogen selectivity of 4.56. Meanwhile, the PEBAX-coated membrane only showed 12.23 and 3.11 GPU for oxygen and nitrogen gas, respectively with a selectivity of 3.94. It can be concluded the PDMS coating is more promising for PSF hollow fiber membrane compared to the PEBAX coating for the oxygen enrichment process.

Hybrid 3-D finite element/MoM analysis for antennas with thin dielectric cover (2002)

A hybrid 3D finite element/method of moments (MoM) method is developed to analyse various antennas that include arbitrarily shaped radiators or feed structures and a thin dielectric layer with or without printed conductors. Structural and material complexity in the radiator and feed structure are easily analysed with FEM while the thin dielectric cover is accounted for by the MoM analysis. This avoids the need to discretize the thin substrate region and rigorously satisfies the radiation condition. Equivalent currents in the MoM analysis are expanded in terms of a triangular basis function that is a simple modification of the edged-based triangular elements used in FEM. Common triangular support and functional form for both the FEM and MoM domain may be more convenient to implement than using alternative elements. The hybrid method is developed and applied to a generic 3-D antenna.
Stable allocations for choice-based collaborative price setting (2022)

Horizontal price agreements can fall within the scope of exemptions to antitrust competition if they are expected to create pro-consumer benefits. Inspired by such horizontal agreements, we introduce a cooperative game in which a set of transport operators can collectively decide at what price to offer sustainable urban mobility services to a pool of travelers. The travelers choose amongst the mobility services according to a multinomial logit model, and the operators aim at maximizing their joint profit under a constant market share constraint. After showing that various well-known allocation rules (i.e., proportional rules and the Shapley value) do not always generate core allocations, we present a core-guaranteeing allocation rule, the market share exchange rule. This rule first allocates to each transport operator the profit he or she generates under collaboration, and then subsequently compensates those transport operators that lose part of their market share, which is paid by the ones that receive some extra market share. This exchange of market share is facilitated by a unique price, which can be expressed as the additional return by cooperating per unit of market share. Finally, we show that, under some natural conditions, the market share exchange rule still sustains the collaboration when the transport operators need to pay back part of the joint profit to society.

CLOTHES DRYING FROM ROOM AIR CONDITIONING WASTE HEAT: THERMODYNAMICS INVESTIGATION (2010)

This paper discusses an experimental study for using heat wasted from a split-type room air conditioner for clothes drying. The study compares the effectiveness of this drying system to a conventional one in terms of duration required to dry the clothes and energy consumption. The objectives of the study are to analyze performance of a room air-conditioner as clothes dryer and to evaluate the effectiveness of its heat waste for a drying system. The experiment is conducted for three drying conditions, namely, outdoor natural drying at midday, indoor natural drying, and drying using air-conditioner waste heat. The study found that using room air-conditioner waste heat for clothes drying is very reliable, especially in congested high-rise residential areas, without additional electricity cost.
Crouching Theropod andNavahopusSauropodomorph Tracks from the Early Jurassic Navajo Sandstone of USA (2008)

Numerous tracks and trackways are preserved in the a cross−strata of the Lower Jurassic Navajo Sandstone of northern Arizona and southern Utah, USA. Tracks and trackways of small theropod dinosaurs are particularly abundant within one 10−m−thick interval. This paper describes a crouching trace from a theropod dinosaur that shows impressions of all four limbs, the ischial callosity, the tail, and tracks leading to and away from the crouching site, and revises the interpretation of a well preserved trackway hitherto referred to the synapsid ichnogenus Brasilichnium and here considered to be from a sauropodomorph dinosaur. It is named Navahopus coyoteensis isp. nov. on the basis of morphological differences from the type ichnospecies N. falcipollex. The ichnofamily Navahopodidae is revised to include Tetrasauropous unguiferus, Navahopus falcipollex, and N. coyoteensis.
Efficient Synthesis of the tRNA Nucleoside PreQ0, 7‐Cyano‐7‐deazaguanosine, via Microwave‐Assisted Iodo→Carbonitrile Exchange (2010)

The naturally occurring tRNA nucleoside preQ(0), 7-cyano-7-deazaguanosine, which is a central intermediate for other natural occurring 7-deazapurine nucleosides was synthesized via a copper(I)-ion-mediated iodo→carbonitrile exchange. The reaction was performed on the easily accessible 7-iodo-7-deazaguanosine under microwave conditions. The overall reaction yield was 30% starting with the glycosylation reaction of the nucleobase. Corresponding 2'-deoxyribonucleosides were prepared following the same route.
Rotor-vortex interaction noise (1983)

A theoretical and experimental study was conducted to develop a validated first principles analysis for predicting noise generated by helicopter main-rotor shed vortices interacting with the tail rotor. The generalized prediction procedure requires a knowledge of the incident vortex velocity field, rotor geometry, and rotor operating conditions. The analysis includes compressibility effects, chordwise and spanwise noncompactness, and treats oblique intersections with the blade planform. Assessment of the theory involved conducting a model rotor experiment which isolated the blade-vortex interaction noise from other rotor noise mechanisms. An isolated tip vortex, generated by an upstream semispan airfoil, was convected into the model tail rotor. Acoustic spectra, pressure signatures, and directivity were measured. Since assessment of the acoustic prediction required a knowledge of the vortex properties, blade-vortes intersection angle, intersection station, vortex stength, and vortex core radius were documented. Ingestion of the vortex by the rotor was experimentally observed to generate harmonic noise and impulsive waveforms.
Improved Recovery of an Ester Flavor Compound by Pervaporation Coupled with a Flash Condensation (1999)

The recovery of an aroma compound, ethyl acetate, highly diluted in model aqueous feeds was carried out with a pervaporation stage coupled to a flash condensation. The permeate, at the vapor state, was selectively fractionated between two condensers in series with decreasing temperatures. A global modeling of the coupling system was proposed, taking into account the extraction step (with transmembrane mass transfer equations) as well as the recovery step (with flash vapor−liquid equilibrium curves). It was shown that the inert gases flowing in the permeate circuit (which were due to unavoidable air leakage) were inducing a dilution of the condensable permeate vapors, leading to a significant lowering of the dew point of the permeate. If compared to pervaporation with conventional total permeate condensation, the coupling of pervaporation with a flash condensation led to a significant enhancement of the selectivity for the recovery of ethyl acetate.
Decidable bounded quantification (1994)

The standard formulation of bounded quantification, system F≤, is difficult to work with and lacks important syntactic properties, such as decidability. More tractable variants have been studied, but those studied so far either exclude significant classes of useful programs or lack a compelling semantics.
Cancer therapy with phytochemicals: evidence from clinical studies. (2015)

Cancer is still one of the major causes of mortality in both developing and developed countries. At present, in spite of intensive interventions, a large number of patients suffer from poor prognosis. Therefore, the effort for finding new anticancer agents with better efficacy and lesser side effects has been continued. According to the traditional recommendations and experimental studies, numerous medicinal plants have been reported to have anticancer effect. Also antiproliferative, pro-apoptotic, anti-metastatic and anti-angiogenic effects of several phytochemicals have been shown in in vitro experiments or animal studies. However, only a small number have been tested in cancerous patients and limited evidence exists for their clinical effectiveness. Also, regarding some phytochemicals, only beneficial effects on cancer-related symptoms or on quality of life have been reported and no positive results exist for their antitumor actions. This review was focused on the phytochemicals whole beneficial effects on various types of cancer have been supported by clinical trials. Based on the literature review, curcumin, green tea, resveratrol and Viscum album were the satisfactory instances of clinical evidence for supporting their anticancer effects. The main findings of these phytochemicals were also summarized and discussed.
Functional studies of epidermal Langerhans cells and blood monocytes in HIV-infected persons. (1995)

APC dysfunction may be important in immune dysregulation associated with HIV disease. Langerhans cells, epidermal APC, can be infected with HIV, although their function in HIV-infected persons has not been studied. Therefore, we studied the immunologic function of Langerhans cells, in parallel with blood APC (enriched for monocytes/macrophages (M phi) function, in 21 HIV-seropositive (HIV+) and 21 HIV-seronegative volunteers, including three monozygotic twin pairs discordant for HIV serology. Langerhans cells from HIV+ patients were quantitatively normal and expressed normal levels of HLA-DR. However, Langerhans cells from AIDS patients and M phi from both AIDS and HIV+ non-AIDS patients stimulated allogeneic T cells less well compared with control APC. In addition, decreased recall Ag- and mitogen-induced T cell responsiveness was observed in HIV+ patients using either autologous Langerhans cells or autologous M phi as APC/accessory cells. Interestingly, Langerhans cells and M phi isolated from HIV+ twins (CD4+ cell counts of 181, 271, and 562/mm3) were able to present recall Ag normally to HIV-uninfected syngeneic T cells. In summary, APC from HIV+ patients were impaired in their ability to generate a primary immune response (i.e., alloantigen-induced T cell stimulation), but they retained the ability to generate a secondary immune response (i.e., recall Ag-induced syngeneic T cell stimulation). Thus, these findings suggest that defects in secondary immune responses commonly observed in HIV disease are dependent on T cell dysfunction alone, whereas defective primary immune responses may be secondary to both T cell and APC dysfunction.
Integrated waveguide photodetectors (1993)

We review recent progress in the monolithic integration of optical waveguides and photodetectors on III-V semiconductors for applications in the 800 - 1600 nm wavelength range. Optical coupling mechanisms and integration techniques are compared in detail, and application to a variety of advanced lightwave receivers is described.
Propagation characteristics of an elliptical chirowaveguide (2009)

The coupled Helmhotz-type differential equations for a general cylindrical structure containing chiral material were transformed into a pair of decoupled equations, and this new set was solved to find expressions for Ez and Hz with the expansion of the complete eigen functions in elliptical chiralwaveguide. There are no pure TE （TM） or even-type （odd-type） modes existing individually in the elliptical structure if Ez and Hz are coupled with each other. The influences of eccentricity and chiral admittance on dispersion of modes are discussed in this paper.
Long-term symptom improvement and patient satisfaction following catheter ablation of supraventricular tachycardia: insights from the German ablation registry (2017)

Ablation therapy for SVT is a safe procedure bringing symptomatic improvement and satisfaction to three quarters of patients after 1 year. Even in patients with arrhythmia recurrence, a high satisfaction level and adherence to the ablating institution could be documented. Strikingly high mortality and stroke rates in follow-up were observed in AFL patients, who apparently need consistent long-term anticoagulation and more medical attention.
BCR/ABL Directly Inhibits Expression of SHIP, an SH2-Containing Polyinositol-5-Phosphatase Involved in the Regulation of Hematopoiesis (1999)

The BCR/ABL oncogene causes chronic myelogenous leukemia (CML), a myeloproliferative disorder characterized by clonal expansion of hematopoietic progenitor cells and granulocyte lineage cells. The SH2-containing inositol-5-phosphatase SHIP is a 145-kDa protein which has been shown to regulate hematopoiesis in mice. Targeted disruption of the murine SHIP gene results in a myeloproliferative syndrome characterized by a dramatic increase in numbers of granulocyte-macrophage progenitor cells in the marrow and spleen. Also, hematopoietic progenitor cells from SHIP(-/-) mice are hyperresponsive to certain hematopoietic growth factors, a phenotype very similar to the effects of BCR/ABL in murine cells. In a series of BCR/ABL-transformed hematopoietic cell lines, Philadelphia chromosome (Ph)-positive cell lines, and primary cells from patients with CML, the expression of SHIP was found to be absent or substantially reduced compared to untransformed cell lines or leukemia cells lacking BCR/ABL. Ba/F3 cells in which expression of BCR/ABL was under the control of a tetracycline-inducible promoter showed rapid loss of p145 SHIP, coincident with induction of BCR/ABL expression. Also, an ABL-specific tyrosine kinase inhibitor, CGP57148B (STI571), rapidly caused reexpression of SHIP, indicating that BCR/ABL directly, but reversibly, regulates the expression of SHIP protein. The estimated half-life of SHIP protein was reduced from 18 h to less than 3 h. However, SHIP mRNA also decreased in response to BCR/ABL, suggesting that SHIP protein levels could be affected by more than one mechanism. Reexpression of SHIP in BCR/ABL-transformed Ba/F3 cells altered the biological behavior of cells in culture. The reduction of SHIP due to BCR/ABL is likely to directly contribute to the pathogenesis of CML.
Joint Intra/Inter-Slot Code Design for Unsourced Multiple Access in 6G Internet of Things (2022)

Unsourced multiple access (UMA) is the technology for massive, low-power, and uncoordinated Internet-of-Things in the 6G wireless system, improving connectivity and energy efficiency on guaranteed reliability. The multi-user coding scheme design is a critical problem for UMA. This paper proposes a UMA coding scheme based on the T-Fold IRSA (irregular repetition slotted Aloha) paradigm by using joint Intra/inter-slot code design and optimization. Our scheme adopts interleave-division multiple access (IDMA) to enhance the intra-slot coding gain and the low-complexity joint intra/inter-slot SIC (successive interference cancellation) decoder structure to recover multi-user payloads. Based on the error event decomposition and density evolution analysis, we build a joint intra/inter-slot coding parameter optimization algorithm to minimize the SNR (signal-to-noise ratio) requirement at an expected system packet loss rate. Numerical results indicate that the proposed scheme achieves energy efficiency gain by balancing the intra/inter-slot coding gain while maintaining relatively low implementation complexity.
Crecimiento del hueso maxilar y colocación de implantes en un paciente joven: Caso clínico (2003)

La literatura avala la eficacia de los implantes osteointegrados en pacientes parcialmente edentulos, pero hay que tener precaucion en los adolescentes con una formacion osea incompleta, ya que los implantes no acompanan al crecimiento normal de los maxilares y se comportan como dientes anquilosados. Tambien podrian interferir en el normal crecimiento del proceso alveolar y comprometer a los germenes de los dientes permanentes adyacentes o alterar su erupcion. La descripcion de este caso analiza los hallazgos clinicos y radiologicos desfavorables de la reposicion de un diente unitario en un varon joven durante un periodo de 15 anos.
Human platelets possess receptors for a lymphokine: demonstration of high specific receptors for HuIFN-gamma. (1987)

This report demonstrates that 125I-recombinant human interferon-gamma (125I-rHuIFN-gamma) binds to high-affinity specific receptors on human platelets. Scatchard analysis of binding data indicates the presence of homogeneous sites estimated in the order of 150 to 200, with an apparent equilibrium dissociation constant, Kd, of 2 X 10(-10) M. The binding of 125I-rHuIFN-gamma to platelet membrane was inhibited by unlabeled rHuIFN-gamma but not by unlabeled rHuIFN-alpha or unlabeled rHuIFN-beta. High affinity binding sites for HuIFN-alpha were not detectable. Cross-linking of 125I-rHuIFN-gamma to platelet membrane proteins with the use of a bifunctional agent (DSS) yielded a predominant complex of 100,000 +/- 5,000 daltons on SDS-PAGE autoradiography, which confirms the presence of specific receptors for IFN-gamma. Two faint bands of lower m.w., 70,000 and 90,000, could also be visualized. Cross-linking of 125I-rHuIFN-alpha to platelet surface could not be demonstrated by using the same procedures. This is the first time that a receptor for a lymphokine (IFN-gamma) has been demonstrated on human platelets. These findings are consistent with data already published, suggesting an interrelationship between IFN and platelet function.
New parastatistics leading to classical thermodynamics: Physical interpretation. II (2014)

In this paper, we refine some of the original notions, such as the number of degrees of freedom, for an arbitrary temperature and an ideal Boltzmann-Maxwell gas. Using the van der Waals model, we illustrate the notion of Frenkel temperature, which separates soft and rigid liquid.
Double slope-assisted Brillouin optical correlation domain analysis (2017)

Fiber-optic Brillouin sensors for temperature and strain distributed monitoring offer unique performance in terms of distance, high spatial resolution and accuracy. Most of the available systems rely on Brillouin Optical Time-Domain Analysis (BOTDA) techniques, which employ pulsed pump signals guaranteeing a spatial resolution fundamentally limited to 1 meter [1]. An attractive alternative approach is the so-called Brillouin Optical Correlation-Domain Analysis (BOCDA), based on the simultaneous phase modulation of both pump and probe waves [2]. In this way, efficient amplification occurs only in a confined fiber section, called correlation peak, where the Brillouin phase-matching condition is satisfied. Correlation peak width can be made arbitrarily narrow and its position along the sensing fiber can be selected by properly tuning the phase modulation rate. Phase-BOCDA sensors can thus guarantee high flexibility in measurement configuration, with spatial resolution that can reach even sub-centimetric scale though at the expense of long acquisition times.
Integrated Kinetic and Thermodynamic Model Describing the Nitrosation of Aniline and Its Derivatives under Reaction- and Encounter-Controlled Conditions (2004)

A kinetic model has been developed that describes the rate of reaction (nitrosation) of aniline and its derivatives with a range of nitrosating agents. This model was derived by first developing a thermodynamic description of the system based on the basicity of the substrate and the nucleophilicity of the nitrosating agent. A kinetic model was obtained by combining the thermodynamic description of the system with experimentally observed kinetics via the transition state theory. The final model exhibited a good correlation with experimental results across a wide range of reactivities. The encounter-controlled regime was also modeled from mass-transfer theory, which was integrated with the kinetic model to describe the rate of nitrosation during the transition regime. Through application of the kinetic model, the intrinsic barrier to reaction was estimated as 15 kJ mol-1.
Effect of breed on the quality attributes of camel meat (2011)

This study was carried out to differentiate between camel breeds with respect to their chemical composition and meat quality characteristics. Four breeds were selected: Magahem, Wodoh, Shoal, and Sofor. The animals’ ages and final weight were approximately 12 months and 281.3±9.32 kg, respectively. To identify the differences between these breeds, we collected 6 longissimus dorsi (LD) and 6 Biceps femoris (BF) muscles from the animals. Meat samples were taken from the LD for chemical composition analysis, and meat quality parameters were characterized for both types of muscles. Assessments were made of the following parameters: myofibril fragmentation index (MFI) score, sarcomere length (SL), fiber area (FA), slice shear force (SSF), pH, loss of volume through cooking, cooking time, and color. The breed groups exhibited significant differences in their fat content as well as differences in SSF values for the LD: Shoa>Wodoh>Sofor>Magahem. The 4 breeds also showed significant differences in LD MFI values. The results indicate that there are significant differences between the breed groups and their muscles with respect to the composition and quality of their meat.
