Fuel Oil Production from Municipal Plastic Wastes in Sequential Pyrolysis and Catalytic Reforming Reactors (2014)

The aim of this research was to study fuel oil production from municipal plastic wastes by sequential pyrolysis and catalytic reforming processes. Three kinds of municipal plastic wastes were collected from the final disposal site and the small recycling company in Yogyakarta city, Indonesia. Commercial Y-zeolite and natural zeolite catalysts were used in this study. The results show that the feedstock types strongly affect the product yields and the quality of liquid and solid products. HDPE waste produced the highest liquid fraction. The catalyst presences reduced the liquid fraction and increased the gaseous fraction. Furthermore, municipal plastic wastes pyrolysis produced higher heating value solid products than those of biomass and low rank coal.

Contributions to the Life History of Adult Pacific Lamprey (Lampetra tridentatd) in the Santa Clara River Of Southern California (2001)

Data on the relative abundance, seasonal timing, and size at entry into freshwater of upstream migrants were collected on a population of Pacific lamprey inhabiting the Santa Clara River. In addition, spent lamprey were also collected and provided information on the length, decrease in body length between entry into freshwater and spawning the following year, and the potential timing of spawning.
Another materialist rhetoric (1998)

This paper argues for a new materialism. Rhetorical studies can achieve a new materialism by emphasizing how rhetoric traverses a governing apparatus as a technology of deliberation. As such, rhetoric makes possible the ability to judge and plan reality in order to police a population. To achieve this new materialism, I argue that rhetorical studies will need to abandon a logic of representation for a logic of articulation to better account for how rhetorical practices distribute different elements into a functioning network of power.
ON SOCIAL NETWORK ANALYSIS IN A SUPPLY CHAIN CONTEXT<sup>*</sup> (2009)

The network perspective is rapidly becoming a lingua franca across virtually all of the sciences from anthropology to physics. In this paper, we provide supply chain researchers with an overview of social network analysis, covering both specific concepts (such as structural holes or betweenness centrality) and the generic explanatory mechanisms that network theorists often invoke to relate network variables to outcomes of interest. One reason for discussing mechanisms is to facilitate appropriate translation and context‐specific modification of concepts rather than blind copying. We have also taken care to apply network concepts to both “hard” types of ties (e.g., materials and money flows) and “soft” types of ties (e.g., friendships and sharing‐of‐information), as both are crucial (and mutually embedded) in the supply chain context. Another aim of the review is to point to areas in other fields that we think are particularly suitable for supply chain management (SCM) to draw network concepts from, such as sociology, ecology, input–output research and even the study of romantic networks. We believe the portability of many network concepts provides a potential for unifying many fields, and a consequence of this for SCM may be to decrease the distance between SCM and other branches of management science.

Cell surface marker profiling of human tracheal basal cells reveals distinct subpopulations, identifies MST1/MSP as a mitogenic signal, and identifies new biomarkers for lung squamous cell carcinomas (2014)

This work provides the largest description to date of molecular diversity among human large airway basal cells. Furthermore, these markers can be used to further study basal cell function in repair and disease, and may aid in the classification and study of SQCCs.
Preparation of<sup>13</sup>C and<sup>15</sup>N labelled RNAs for heteronuclear multi-dimensional NMR studies (1992)

A procedure is described for the efficient preparation of isotopically enriched RNAs of defined sequence. Uniformly labelled nucleotide 5'triphosphates (NTPs) were prepared from E.coli grown on 13C and/or 15N isotopically enriched media. These procedures routinely yield 180 mumoles of labelled NTPs per gram of 13C enriched glucose. The labelled NTPs were then used to synthesize RNA oligomers by in vitro transcription. Several 13C and/or 15N labelled RNAs have been synthesized for the sequence r(GGCGCUUGCGUC). Under conditions of high salt or low salt, this RNA forms either a symmetrical duplex with two U.U base pairs or a hairpin containing a CUUG loop respectively. These procedures were used to synthesize uniformly labelled RNAs and a RNA labelled only on the G and C residues. The ability to generate milligram quantities of isotopically labelled RNAs allows application of multi-dimensional heteronuclear magnetic resonance experiments that enormously simplify the resonance assignment and solution structure determination of RNAs. Examples of several such heteronuclear NMR experiments are shown.
Circuits for Traveling-Wave Tubes (1949)

The comparison between traveling-wave-tube circuits of different geometries can be facilitated by the use of phase velocity, group velocity, and stored energy as parameters. For a given stored energy per unit length, lowering the group velocity with respect to the phase velocity increases circuit impedance (and, hence, gain), increases attenuation, and narrows the band. A filter-type circuit consisting of pillbox resonators is shown to be much inferior electrically to a helix. Expressions are presented showing the effect of gap length in filter-type circuits consisting of pillbox resonators, and the attenuation is calculated for such circuits.
Hydrothermal Synthesis and Characterization of Two New Microporous Zinc-Substituted Gallium Phosphates Templated by Diaminocyclohexane:  (H<sub>2</sub>DACH)<sub>2</sub>[Zn<sub>4</sub>Ga<sub>2</sub>(HPO<sub>4</sub>)<sub>3</sub>(PO<sub>4</sub>)<sub>4</sub>] and (H<sub>2</sub>DACH)[Zn<sub>2</sub>Ga<sub>2</sub>(PO<sub>4</sub>)<sub>4</sub>] (2000)

Two new zinc-substituted gallophosphates, (H2DACH)2[Zn4Ga2(HPO4)3(PO4)4] (1) and (H2DACH)[Zn2Ga2(PO4)4] (2), have been synthesized under mild hydrothermal conditions and characterized by single-crystal X-ray diffraction, solid-state NMR spectroscopy, and thermogravimetric analysis. Both structures are built up with MO4 (M = Zn, Ga) and PO4 (or HPO4) tetrahedra. Compound 1 adopts a novel microporous framework which contains the highest transition-metal concentration of any MGaPO. The structure may be viewed as stacking of [Zn2Ga(HPO4)2(PO4)2]2 layers along a linked by extra HPO4 tetrahedra as pillars to generate intersecting 12-ring channels with dimensions ∼8.1 × 8.1 Å. Compound 2 has a CGS framework topology but a higher divalent-metal content than the isostructural materials of (C7NH14)[MGa3P4O12] (M = Co, Zn). Diprotonated 1,2-diaminocyclohexane (DACH) cations are ordered at the intersections of two interconnected channels in both 1 and 2. They represent the first zinc-substituted gallophosphate templated by dibasic amine and showing distinguishable Zn sites. The solid-state 31P MAS NMR spectrum of 1 showed a resonance for the HPO42- group that was shifted downfield by ∼8 ppm relative to the PO43- group. On the basis of the results of TG/DT analyses, both frameworks can be thermally stable up to ∼300 °C. Crystal data: 1, monoclinic, C2/c, a = 23.568(1) Å, b = 10.242(1) Å, c = 16.235(1) Å, β = 108.115(1)°, Z = 4; 2, monoclinic, P21/c, a = 14.320(1) Å, b = 16.255(1) Å, c = 8.855(1) Å, β = 90.134(1)°, Z = 4.
Attenuation of Autonomic Nervous System Functions in Hypertensive Patients at Rest and During Orthostatic Stimulation (2008)

The effect of age on autonomic nervous system was assessed at rest and while standing using systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate, and power spectral analysis of the time duration between 2 consecutive R waves of an electrocardiogram (RR) interval variability, as well as on plasma norepinephrine and epinephrine levels in mild to moderate hypertensive patients (DBP, 90-110 mm Hg). Patients younger than 60 years (n=57) and older than 60 years (n=32), were evaluated after a 3- to 4-week placebo period. Plasma catecholamines were measured in the supine position at rest and after 10 minutes of standing. Power spectral analysis of the RR interval variability was performed in each condition using the high-frequency (HF) band (0.15-0.4 Hz) as an index of parasympathetic activity and the low-frequency (LF) band (0.05-0.15 Hz) and LF-HF ratio to estimate sympathetic activity. The total power was calculated as the sum of LF and HF power. supine SBP was significantly higher in older patients (P<.05). SBP and DBP increased significantly only in younger patients during standing (P<.05), while the changes were smaller and nonsignificantly lower in older patients. HR was similar in both groups at rest and increased similarly during standing. Norepinephrine and epinephrine levels were similar at rest and increased similarly in both groups of patients during standing. At rest, lower LF and HF components were observed in older patients. The LF component increased less and the HF component decreased less in older patients during standing. A lower sympathetic and parasympathetic basal cardiac tone was observed at rest in older hypertensive patients. Moreover, reduced hemodynamic and sympathetic responses to standing as assessed by SBP, DBP, and the LF component of HR variability were observed in older hypertensives in the presence of a normal catecholamine response. These observations could reflect a decreased sensitivity of cardiac beta-adrenoceptors with aging.
Sodium bicarbonate in seminal plasma stimulates the motility of mammalian spermatozoa through direct activation of adenylate cyclase. (1985)

Recently, a low molecular weight factor, which specifically stimulates sperm adenylate cyclase, was found in porcine seminal plasma (Okamura, N., and Sugita, Y. (1983) J. Biol. Chem. 258, 13056-13062). The purified factor was analyzed by 1H NMR, 13C NMR, infrared spectroscopy, and elementary analysis and identified as sodium bicarbonate. The effects of sodium bicarbonate both on adenylate cyclase activity in porcine spermatozoa and on sperm motility have been studied. Sperm adenylate cyclase was found to be specifically activated by bicarbonate over the physiological concentration range. In contrast, the adenylate cyclase activity in other tissues was not affected. The same concentration range of bicarbonate which resulted in activation of adenylate cyclase also stimulated sperm motility. The motility and enzyme activity of spermatozoa in all species so far tested (human, bovine, rat, mouse, and dog) were found to be similarly sensitive to bicarbonate concentration. These results show that the bicarbonate-sensitive adenylate cyclase system regulates sperm motility and suggest that this system is common to all mammals.
Hypomethylation and expression of BEX2, IGSF4 and TIMP3 indicative of MLL translocations in Acute Myeloid Leukemia (2009)

These results suggest that the conspicuous expression of the TSG BEX2, IGSF4 and TIMP3 in MLLmu AML cell lines is the consequence of altered epigenetic properties of MLL fusion proteins.
The age penalty and its effect on cache performance (2001)

Web content caching is recognized as an effective mechanism to decrease server load, network traffic, and user-perceived latency. An HTTP compliant cache associates with each cached object an expiration time calculated according to directives set by the object&apos;s origin server. The cache incurs a miss when it has no cached copy of a requested object or when the existing copy had expired (is not fresh). Upon a miss, the cache needs to fetch or validate a copy through exchanges with another cache with a fresh copy or the origin server. Thus, misses generate traffic and prolong service times. Caches are deployed as proxies, reverse proxies, and hierarchically and as a result, caches often serve other caches. As this happens, content age at higher-level caches, in addition to availability and freshness, emerges as a performance factor. The age of a cached copy of an object is the elapsed time since fetched from the respective origin. Fresh cached copies of the same object can have different ages and older copies typically expire sooner. Therefore, a proxy cache would suffer a higher miss rate if it receives older objects (e.g., from a reverse-proxy cache). Similarly, reverse-proxy caches that serve proxy-caches receive more requests than an origin server would have received. We refer to the increase in miss rate due to age as the age penalty. We use trace-based simulations to measure the extent of the age penalty for content served by content delivery networks and large caches. Even though the age penalty had not been considered previously, we demonstrate that it can be significant, and moreover, can highly vary under different practices.

Disruption of phospholipase B gene, PLB1, increases the survival of baker's yeast Torulaspora delbrueckii (1996)

An uracil auxotrophic mutant of baker's yeast Torulaspora delbrueckii, which is resitant to 5-fluoro-orotic acid, was complemented by transformation with YEp24 which harbors 2 µm origin and URA3 derived from Saccharomyces cerevisiae. The phospholipase B in T. delbrueckii cells is active in both acidic and alkaline conditions. However, activity of phospholipase B gene (PLB1) in cells of disruption mutant (plbI : : URA3) was lost in both conditions, which indicates that all phospholipase B activity is encoded by a single gene (or a single polypeptide) in these yeast cells. Over-expression of PLB1 with YEp plasmid vector in T. delbrueckii cells showed ≈ 2.5-fold increase in phospholipase B activity, comparing with that in wild-type cells. Cells of plb1Δ mutant showed increased survival when cells of plb1Δ mutant and wild-type strain were incubated in water at 30 °C. Cells of PLB1-over-expressed strain died rapidly even during the cultivation period, indicating that phospholipase B activity may be a determinant for the survival of this yeast.
Direct Aerosol Printing of Lithium-ion Batteries (2017)

Abstract Recently, additive manufacturing (AM) has brought new opportunities to the manufacturing of lithium-ion batteries (LIBs). In this study, aerosol jet printing, as a branch of AM technologies was demonstrated to fabricate lithium-ion batteries for the first time. Printable inks of two pairs of active materials for cathode and anode were developed. The effect of ink composition on the printing characteristics was studied. The developed inks were printed into Li-ion battery electrodes with specific capacities comparable to conventional slurry cast electrodes. Next, to demonstrate fully-printed electrodes, gold and copper inks were printed on top of polymer substrates and thermal/flash sintered as the current collectors for cathode and anode.
PROTECTION OF ISLETS OF LANGERHANS FROM INTERLEUKIN-1 TOXICITY BY ARTIFICIAL MEMBRANES (1990)

Recently it has been reported that interleukin 1 may play a central role in the immune destruction of islets. Since the mass weight of interleukin-1 is close to that of insulin, destruction of transplanted islets may be possible although they are enclosed in membranes that prevent penetration by immune-competent cells and cyto-toxic antibodies. The present in vitro study showed that the encapsulated rat islets are protected from high doses of IL-1 (1000 ng) inside a hollow fiber membrane with a cutoff of 50,000 D. The function of islets in a free-floating culture, however, was suppressed in a dose-dependent manner (1000 ng/L; 20-30% of controls). Histologically, no damage of the free-floating or encapsulated islets was observed at 1000 ng of IL-1-containing medium. Islets washed out of the devices after 2 days of exposure to IL-1 showed no difference in glucose-stimulated insulin release when compared with islets not exposed that were kept in free-floating culture. It is suggested that an unspecific coating of the membranes by serum proteins (containing physiological IL-1 antagonists) may cause the protective effect.
Parkinson's disease and Parkinson's disease medications have distinct signatures of the gut microbiome (2017)

PD is accompanied by dysbiosis of gut microbiome. Results coalesce divergent findings of prior studies, reveal altered abundance of several taxa, nominate functional pathways, and demonstrate independent effects of PD medications on the microbiome. The findings provide new leads and testable hypotheses on the pathophysiology and treatment of PD. © 2017 International Parkinson and Movement Disorder Society.
DC-bus voltage control of three-phase AC/DC PWM converters using feedback linearization (2000)

In this paper, a fast voltage control strategy of three-phase AC/DC pulsewidth modulation (PWM) converters applying a feedback linearization technique is proposed. First, incorporating the power balance of the input and output sides in system modeling, a nonlinear model of the PWM converter is derived with state variables such as AC input currents and DC output voltage. Then, by input-output feedback linearization, the system is linearized and a state feedback control law is obtained by pole placement. With this control scheme, output voltage responses become faster than those in a conventional cascade control structure. For robust control to parameter variations, integrators are added to the exact feedback control law. Since the fast voltage control is feasible for load changes, it is shown that the DC electrolytic capacitor size can be reduced. In addition, the capacitor current is analyzed for size reduction of the capacitor. As is usual with PWM converters, the input current is regulated to be sinusoidal and the source power factor can be controlled at unity. The experimental results are provided to verify the validity of the proposed control algorithm for a 1.5 kVA insulated gate bipolar transistor PWM converter system.
Epitaxial thin film GaAs deposited by MOCVD on low-cost, flexible substrates for high efficiency photovoltaics (2013)

Growth of epitaxial GaAs thin film on flexible, inexpensive substrates can open up the possibility of fabricating affordable and high efficiency III-V photovoltaics which may lead to a complete transformation of the PV market. Here we report the successful hetero-epitaxial growth of GaAs thin film by metal organic chemical vapor deposition on single-crystallinelike Ge thin film on flexible metal foils. GaAs epilayers showed (00l) orientation with zinc blende structure and good optoelectronic quality with minimal thermoelastic/lattice mismatch strain. High doping density due to Ge diffusion from the substrate was observed in the GaAs film with a Hall mobility of 285 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> /V-s. XPS depth profiles showed significant diffusion of Ge in GaAs thin film.
<i>In vivo</i> conversion of adult <i>α</i> ‐cells into <i>β</i> ‐like cells: a new research avenue in the context of type 1 diabetes (2011)

Type 1 diabetes is caused by the loss of insulin-producing β-cells as a result of an autoimmune condition. Despite current therapeutic approaches aimed at restoring the insulin supply, complications caused by variations in glycaemia may still arise with age. There is therefore mounting interest in the establishment of alternative therapies. Most current approaches consist in designing rational protocols for in vitro or in vivo cell differentiation/reprogramming from a number of cell sources, including stem, progenitor or differentiated cells. Towards this ultimate goal, it is clear that we need to gain further insight into the interplay between signalling events and transcriptional networks that act in concert throughout pancreatic morphogenesis. This short review will therefore focus on the main events underlying pancreatic development with particular emphasis on the genetic determinants implicated, as well as on the relatively new concept of endocrine cell reprogramming, that is the conversion of pancreatic α-cells into cells displaying a β-cell phenotype.
Enhancing Asset Search and Retrieval in a Services Repository using Consumption Contexts (2007)

Software organizations wanting to implement a systematic reuse program face the challenge of organizing and cataloging their software assets so that they can be retrieved in different contexts of usage across their divisions. With the advent of services-oriented architectures (SOA), of which Web services is an example, software components are readily available as services on the web using standard protocols. However, service descriptions are usually only those that are provided by the service producers and unless a service producer has thought about all the contexts in which its service may be used, there is no guarantee that the service can be retrieved with high recall. In this paper, we investigate how different contexts of asset consumption may be used for better asset modeling and discovery. We introduce an extensible set of consumption factors where the service descriptions may be provided by the service producer or other roles, implement a prototype that can evolve with the modeled factors, and demonstrate that the solution enables improved precision and recall for services available in a large-scale software organization.
<i>Mycobacterium tuberculosis</i> Heat Shock Fusion Protein Enhances Class I MHC Cross-Processing and -Presentation by B Lymphocytes (2005)

Exogenous heat shock protein (HSP):peptide complexes are processed for cross-presentation of HSP-chaperoned peptides on class I MHC (MHC-I) molecules. Fusion proteins containing HSP and Ag sequences facilitate MHC-I cross-presentation of linked antigenic epitopes. Processing of HSP-associated Ag has been attributed to dendritic cells and macrophages. We now provide the first evidence to show processing of HSP-associated Ag for MHC-I cross-presentation by B lymphocytes. Fusion of OVA sequence (rOVA, containing OVA(230-359) sequence) to Mycobacterium tuberculosis HSP70 greatly enhanced rOVA processing and MHC-I cross-presentation of OVA(257-264):K(b) complexes by B cells. Enhanced processing was dependent on linkage of rOVA sequence to HSP70. M. tuberculosis HSP70-OVA fusion protein enhanced cross-processing by a CD91-dependent process that was independent of TLR4 and MyD88. The enhancement occurred through a post-Golgi, proteasome-independent mechanism. These results indicate that HSPs enhance delivery and cross-processing of HSP-linked Ag by B cells, which could provide a novel contribution to the generation of CD8(+) T cell responses. HSP fusion proteins have potential advantages for use in vaccines to enhance priming of CD8(+) T cell responses.
