Gasification of Fuel Cane Bagasse in a Downdraft Gasifier: Influence of Lignocellulosic Composition and Fuel Particle Size on Syngas Composition and Yield (2011)

Gasification of fuel cane bagasse briquettes and pellets was carried out in a novel 50 kWe downdraft autothermal gasifier to evaluate the most suitable densified form for use in downdraft gasifiers. The results showed that the calorific value of the syngas produced from the briquettes was low, ranging from 1.95 to 3.12 MJ/m3n, and ballooning of the briquettes accompanied by bridging of the fuel repeatedly occurred in the pyrolysis and throat zones. In contrast, gasification of pelletized bagasse under similar operating conditions produced syngas ranging in calorific value from 4.90 to 5.94 MJ/m3n, the syngas yield increased by 65%, and bridging was non-existent. Investigation of the lignocellulose composition of the bagasse found that this high-fiber cane has a high lignin/cellulose ratio with a typical lignin content of 33 ± 4%. Scanning electron microscopy studies of the partially pyrolyzed and expanded briquettes showed that extensive porous structures had developed during pyrolysis. Because cellulose devolatilizes at a faster rate than lignin, this suggested that, during pyrolysis, the rapid production of volatile gases within the briquettes resulted in ballooning and cracking of these structures. This increase in volume coupled with the reduced mass of the briquette resulted in reduced bulk density, which restricted the capacity of the fuel bed to flow under gravity and ultimately led to bridging in the reactor, poor syngas composition, and low yield.
New Materials in Hydrothermal Synthesis (2000)

In this Account we describe the hydrothermal synthesis of some new materials including microporous crystals, ionic conductors, complex oxides and fluorides, low-dimensional aluminophosphates, inorganic-organic hybrid materials, and particularly condensed materials such as diamond and inorganic helical chains. Hydrothermal synthesis in biology and environment sciences is also introduced. The increasing interest in hydrothemal synthesis derives from its advantages in terms of high reactivity of reactants, easy control of solution or interface reactions, formation of metastable and unique condensed phases, less air pollution, and low energy consumption.
Use of response surface methodology to describe the combined effects of pH, temperature and E/S ratio on the hydrolysis of dogfish (<i>Squalus acanthias</i>) muscle (1996)

Abstract Response surface methodology was used to study the effects of pH, temperature and enzyme – substrate ratio (E/S) on the degree of hydrolysis (DH) of dogfish muscle protein. The effect of the hydrolysis variables was described using a three-level Box–Behnken factorial design giving a mathematical model that shows the influence of each variable and their interactions. Based on degree of hydrolysis (DH) of the original substrate, the hydrolysis variables were optimized at a pH of 8.3, a hydrolysis temperature of 53.6°C and an E/S of 3.6% (w/w). The coefficient of determination (R2ad) was greater than 95%, and a lack-of-fit test revealed a non-significant value for the DH model equation, indicating that the regression equation was adequate for predicting the degree of hydrolysis under any combination of values of the variables.
Semantic interpretation of object activities in a surveillance system (2003)

Activity analysis and semantic interpretation of tracked targets in a dynamic image sequence has recently attracted more attentions in computer vision. In this paper, a framework for semantic interpretation of vehicle and pedestrian behaviors is proposed for practical applications in visual traffic surveillance. The trajectories recorded in the visual tracking process are analyzed using dynamic clustering and classification on which high level semantic interpretation is based Experimental results are presented to illustrate the performance of the proposed algorithm.
Some Results of the Earliest Deadline Scheduling Algorithm (1989)

Abmw&-Task scheduling is an important issue in the design of a renl-timc computer system because tasks have execution deadlines that must be met, otherwise the system fails with severe consequences upon the environment. In this paper, we study the problem of scheduling periodic time critical tasks on a monoprocessor system. A periodic time critkal task consists of an infinite number of -quests, each of whieh has a prescribed deadline. Tasks are assumed to meet their timing requirements when scheduled by the Earliest Deadline algorithm and preemptions are allowed. We report results from some investigations into the problem of making optimum use of the remaining processor idle time in scheduling perlodk tasks either as soon as possible M as late as possible. The major results consist of the statement and proof of properties relating to bcdhtion and duration of idle time intervals and enable us to provide an elRcient algorlthm lor determining maximum quantity of total idle time available between any two instants. We describe how these results can be applied, Brst to the decision problem that arises when a sporadic time critical task occurs and requires to be run at an unpredictable time and second, to the scheduling problem that arises in a fault tolerant system using the deadline mechanism for which each task implements primary and alternate algorithms. Index Terms-Deadline mechanism, idle time, preemptive schedul
Additive Effects of Atrial Natriuretic Peptide and Angiotensin II on Luteinizing Hormone and Prolactin Release in Female Rats (1990)

The present experiments were designed to assess the effects of central administration of atrial natriuretic peptide (ANP), alone or in conjunction with angiotensin II (AII), on luteinizing hormone (LH) and prolactin release in ovarian steroid-primed female rats. Intracerebroventricular injection of ANP (200 ng/2 microliters over 1 min) induced an increase in plasma LH levels without significantly affecting prolactin release. Injection of AII (50 ng/2 microliters over 1 min) also resulted in an increase in LH levels and, in addition, reduced plasma prolactin titers. Coinjection of ANP and AII did not elevate LH levels beyond that achieved by either peptide alone, but produced a further suppression in prolactin levels than that seen with AII alone. Water intake induced by AII was attenuated by coadministration of ANP. In a second protocol utilizing lower doses of the peptides delivered by infusion, either ANP (800 ng/h; 13.3 ng/min) or AII (200 ng/h; 3.3 ng/min) alone produced 100% increases in LH levels. Coinfusion of the peptides induced an additive (250%) increase in plasma LH titers. In this protocol, the release of prolactin was unaffected by infusion of the peptides, either alone or as a comixture. Water intake induced by AII infusion was attenuated by coadministration of ANP. Taken together, these experiments demonstrate that, in contrast to the antagonistic interaction of ANP and AII on water intake, the peptides affect reproductive hormone secretion in the same direction and, under particular experimental conditions, display additive effects in stimulating LH and inhibiting prolactin release.
Cholesterol distribution between high-density-lipoprotein subfractions HDL2 and HDL3 determined in serum by discontinuous gradient gel electrophoresis (1991)

We used discontinuous gradients of polyacrylamide gel to determine the high-density-lipoprotein (HDL) subfractions HDL2 and HDL3 of serum lipoproteins. Serum (40 microL) prestained with Sudan Black was electrophoresed in cylindrical tubes over successive layers of 3.5%, 6%, 13%, and 17.5% acrylamide gels in a Tris.glycine buffer (3-4 h, 300 V). Very-low- (VLDL) and low-density lipoprotein (LDL) were retained by the 3.5% and 6% gels. HDL2 was concentrated at the interface between the 13% and 17.5% gels, and HDL3 migrated into the 17.5% gel. The distribution between HDL2 and HDL3 was obtained by densitometric scanning. Application of the respective percentages to HDL cholesterol assayed after phosphotung-state-Mg2+ precipitation of VLDL and LDL gave calculated concentrations of HDL2 and HDL3 cholesterol. The calculated values for HDL2 cholesterol were in excellent agreement with those for HDL2 isolated by ultracentrifugation (r = 0.920 for n = 120 sera; differences nonsignificant by Student's paired t-test). Besides being highly discriminating, the method is rapid, easily performed, and economical.
A Quasi-Four-Pair Class-E CMOS RF Power Amplifier With an Integrated Passive Device Transformer (2009)

A quasi-four-pair structure of an RF CMOS power amplifier (PA) is proposed. The structure is applied to a 1.8-GHz class-E CMOS PA for a global system for mobile communications with a 0.18-mum RF CMOS process. This allows a simple design, as well as a high output power. The transistor size issues of the cascode PA are also studied. An integrated passive device transformer is used as both a power combiner and a matching circuit of the power stage. The results show an output power of 33.4-33.8 dBm and a power-added efficiency of 47.4%-50% with a supply voltage of 3.3 V at a frequency range of 1.71-1.91 GHz.

Glass fiber hermetic seals using a CO_2 laser (1975)

Glass fibers of approximately 0.13-mm diam have been hermetically sealed through windows of Corning Code 7740 glass and Code 7052 glass, and into B(2)O(3)-3SiO(2) glass as well. The seals were made with a 50-W CO(2) laser at a power level of about 5 W. Transmission loss tests show a transit loss of <0.2 dB for a B(2)O(3)-3SiO(2) clad fused silica fiber through a Corning Code 7740 glass window.
Unipycation (2013)

Language composition approaches have traditionally suffered from poor performance. In this paper we hypothesise that meta-tracing provides a means to compose independent language interpreters while retaining the performance levels of each. To study this approach, we compose Python and Prolog interpreters to form Unipycation. We present a case study of its use and a suite of micro-benchmarks which give us some understanding of its cross-language performance.
Consistent Nonparametric Regression (1977)

Let $(X, Y)$ be a pair of random variables such that $X$ is $\mathbb{R}^d$-valued and $Y$ is $\mathbb{R}^{d'}$-valued. Given a random sample $(X_1, Y_1), \cdots, (X_n, Y_n)$ from the distribution of $(X, Y)$, the conditional distribution $P^Y(\bullet \mid X)$ of $Y$ given $X$ can be estimated nonparametrically by $\hat{P}_n^Y(A \mid X) = \sum^n_1 W_{ni}(X)I_A(Y_i)$, where the weight function $W_n$ is of the form $W_{ni}(X) = W_{ni}(X, X_1, \cdots, X_n), 1 \leqq i \leqq n$. The weight function $W_n$ is called a probability weight function if it is nonnegative and $\sum^n_1 W_{ni}(X) = 1$. Associated with $\hat{P}_n^Y(\bullet \mid X)$ in a natural way are nonparametric estimators of conditional expectations, variances, covariances, standard deviations, correlations and quantiles and nonparametric approximate Bayes rules in prediction and multiple classification problems. Consistency of a sequence $\{W_n\}$ of weight functions is defined and sufficient conditions for consistency are obtained. When applied to sequences of probability weight functions, these conditions are both necessary and sufficient. Consistent sequences of probability weight functions defined in terms of nearest neighbors are constructed. The results are applied to verify the consistency of the estimators of the various quantities discussed above and the consistency in Bayes risk of the approximate Bayes rules.

Plant Litter and Establishment of Alien Annual Weed Species in Rangeland Communities (1970)

Plant litter that covers the soil surface acts as a layer of insulation moderating temperature and moisture, and creating favorable microsites for germination and the establishment of annual weed species in rangeland communities. Litter cover is an important factor in succession among annual species which culminates in dominance by downy brome ( Bromus tectorum L.) and medusahead ( Taeniatherum asperum (Sim.) Nevski) in these communities.

Cytokines, neurotrophins, and oxidative stress in brain disease from mucopolysaccharidosis IIIB (2006)

Mucopolysaccharidosis IIIB (MPS IIIB; Sanfilippo syndrome type B) is characterized by profound neurological deterioration. Because a murine model of MPS IIIB disease is available, we focused on analysis of gene expression in the brain and cerebellum of 7-month-old MPS IIIB mice by pathway-specific filter microarrays designed to probe apoptotic-related, neurotrophic signalling molecules and inflammatory cytokines and receptors. Moreover, we extended the analysis with real-time PCR performed at 1, 3, 7 months after birth. Bdnf was down-regulated in the brain but up-regulated in the cerebellum at 7 months of age, both at RNA and at protein levels. Cbln1 presented a threefold increase in the oldest brains while remaining unaltered in the cerebellum. Ccl3, Casp11, gp91(phox), p67(phox), and p47(phox) showed an increased expression in both brain and cerebellum at each examined time point. Ccl3, in particular, exhibited in both organs and at all times tested approximately a tenfold increase in its expression. Insofar as p47(phox), p67(phox), and gp91(phox) are all components of the phagocyte NADPH oxidase, our results suggest the possible involvement of the reactive oxygen species in the genesis of neurodegeneration in MPS IIIB disease.

Excitation mechanisms in woodwind and brass instruments (1979)

A general analysis is given of the behaviour of musical instruments driven by a reed mechanism. Attention is concentrated on the reed mechanism itself and a clear distinction is drawn between the behaviour of reeds striking inwards (as in the clarinet, oboe and organ pipe) and reeds striking outwards (as in the trumpet and other brass instruments). Impedance curves are calculated for reed generators of each type and it is shown that sounding of the instrument requires that the acoustic admittance of the reed, as seen from inside the mouthpiece, should have a negative real part of larger magnitude than the real part of the pipe admittance. This implies that there is a minimum permissible blowing pressure for each reed configuration. A reed striking inwards must operate at a frequency below the reed resonance and below but close to the frequency of an impedance maximum for the pipe. A reed striking outwards must operate at a frequency above and close to the reed resonance and above and close to an impedance maximum for the pipe. Brief consideration is given to other matters, including non-linearities and their role in limiting oscillation amplitude and in generating harmonics.
Early gene expression of hepatocyte growth factor in mononuclear phagocytes of rat liver after administration of carbon tetrachloride (2002)

Abstract: Background: Hepatocyte growth factor (HGF) is a potent hepatocyte mitogen supposed to be a main stimulant of hepatocyte replication during liver regeneration. During acute liver injury, HGF has been detected in nonparenchymal cells of the liver. Methods: We performed in situ hybridization of HGF in rat livers after administration of carbon tetrachloride (CCl 4 ). Mononuclear phagocytes (MNP) were isolated from normal and injured livers and HGF expression was analyzed by Northern blotting, in situ hybridization, and immunoprecipitation of 35 S‐labeled proteins. Results: In situ hybridization of normal liver revealed few HGF positive cells within hepatic sinusoids. In injured livers, the number of cells containing HGF transcripts was increased at 6–24 h after CCl 4 .Hepatocyte growth factor transcripts in MNP from normal liver were detectable in trace amounts, but became clearly detectable at 6 h and persisted up to 24 h after CCl 4 administration. In situ hybridization of MNP isolated from normal liver did not reveal positive cells. Mononuclear phagocytes became HGF‐positive when isolated 6 h after CCl 4 . Hepatocyte growth factor protein was detected in MNP isolated 24 h after CCl 4 . Conclusions: Hepatocyte growth factor in MNP is not directly induced by interferon‐α, interferon‐γ or tumour necrosis factor‐α (TNF‐α).Stimulated resident mononuclear phagocytes may play a significant role in the increase of HGF expression in liver regeneration after acute liver injury.
A hardware and software monitor for high-level system-on-chip verification (2002)

Verification of today's Systems-on-Chip (SoC) occurs at low abstraction-levels, typically at register-transfer level (RTL). As the complexity of SoC designs grows, it is increasingly important to move verification to higher abstraction-levels. Hardware/software co-simulation is a step in this direction, but is not sufficient due to inaccurate processor models, and slow hardware simulation speeds. System-level monitoring commonly used for event-based software debugging, provides information about task scheduling events, inter-task communication and synchronisation, semaphores/resources, I/O interrupts, etc. We present MAMon, a monitoring system that can both monitor the logic-level and the system-level in single/multiprocessor SoCs. A small hardware probe-unit is integrated in the SoC design and connects via a parallel-port link to a host-based monitoring tool environment. The probe-unit collects all events in the target system in run-time, and time-stamps them with a resolution of 1 /spl mu/s. The events are then stored in a database on the host for further processing. The paper will describe MAMon and how it works for software and hardware monitoring. The paper also describe how system-level monitoring can be achieved non-instrusively by using a hardware-based real-time kernel.

Nitrogen use efficiency and recovery from N fertilizer under rice-based cropping systems (2009)

Broad bean-rice, hairy vetch-rice, naked barley-rice and fallow-rice cropping systems was investigated at Kyoto University Farm, Takatsuki, Japan during 2001-2002 and 2002-2003 to determine the effects of broad bean and hairy vetch on seasonal crop N accumulation, fertilizer N use efficiency (FNUE) and N recovery from rice-based cropping systems using 15N-labeled fertilizer. Cropping systems used as main plot treatments and N fertilizer at rates of 0, 40, 80 and 120 kg ha-1 as subplot treatments. Hairy vetch added 6.4 to 13.1 g N m-2 of which 1.4 to 5.4 g fixed N m-2 while broad bean added 32.0 to 35.2 g N m-2 of which 18.1 to 27.5 g fixed N m-2 to the soil when incorporated as green manure. Broad bean-rice accumulated 19.4 to 20.4 and 21.4 to 22.6 g N m-2 and hairy vetch-rice accumulated 12.9 to 18.7 and 13.2 to 16.4 g N m-2 in 2002 and 2003, respectively. In 2002, FNUE was highest in hairy vetch-rice with N 40 kg ha-1 while in 2003 FNUE was highest in naked barley-rice with N 40 kg ha-1. In broad bean-rice, plant nitrogen accumulation at maturity always increased and FNUE decreased in spite of increased grain yield of rice. The highest (94 %) recovery of 15N-labeled fertilizer was achieved in rice after broad bean with N 40 kg ha-1 and the recoveries of 15N-labeled fertilizer were higher in the first year than the second year.
Hypertrophic cardiomyopathy: A review of literature on clinical status and meta-analysis of diagnosis and clinical management methods (2018)

Cardiomyopathies are a major cause of heart failure and one of the leading indication for cardiac transplantation. Hypertrophic cardiomyopathy (HCM) is the second most frequently encountered phenotype of cardiomyopathy in clinical practice after dilated cardiomyopathy (DCM). Early identification and prompt treatment of patients with HCM at increased risk of death is imperative in clinical management. Thus, this article aggregates available research-based evidence to provide a comprehensive review of HCM. The goal is to advance the knowledge and understanding of HCM and improve its diagnosis and management. The review is organized into eleven main sections. The initial sections introduce and define HCM, review forms of HCM, its epidemiology (risk and prevalence rates in defined populations), clinical signs and symptoms, prognosis and risk markers. The latter sections review the pathophysiology of HCM, the etiologic agents, differential diagnosis and clinical management of HCM. The review also includes a meta-analysis of diagnostic and clinical management methods.
The transport of proteins into the nucleus requires the 70-kilodalton heat shock protein or its cytosolic cognate. (1992)

The 70-kDa heat shock protein hsp70 and its constitutively expressed cognate, hsc70, are abundant proteins implicated in a number of cellular processes. When a permeabilized cell system for examining the transport of proteins into the nucleus is depleted of hsc70 and hsp70, either by affinity chromatography on ATP-agarose or with antibodies against these proteins, nuclear transport activity is lost. Full activity is restored by the addition of HeLa proteins that bind to ATP-agarose. hsc70 and hsp70 are the active factors, since activity is also fully restored by the addition of either recombinant hsc70 or hsp70 which has been bacterially expressed and highly purified. The restoration of activity is saturable. The transport system requires other cytosolic factors as well, including at least one protein that is sensitive to inactivation by N-ethylmaleimide, but neither hsc70 nor hsp70 is the sensitive protein.
