Brazilian higher education : characteristic and challenges (1998)

Higher education in Brazil is at a crossroads, with the Government exploring alternatives to address critical issues on the subject. This report aims at providing a description and policy assessment of the present system. First, essential characteristics of the system are reviewed, such as the institutions, student enrollment, cost and funding sources, institutional autonomy, and policy goals, among others. Secondly, the report examines the principal policy challenges, questioning the possibility of an adequate supply of qualified students, as well as the socio-economic and income level concerns of an expanded cohort. Further issues are discussed including the extent to which there should be higher education institutions which provide less than degree level; and whether public funding for higher education should be linked to the ownership of the institution offering the education, or to the student undertaking the education. The study views the need for Brazil to support the development of a greater capacity for planning and program improvement within its universities, thus achieving a balanced approach to quality assurance.

A novel architecture design for MP3 audio decoder (2001)

MPEG Layer III (MP3) Audio decoding algorithm is involved in several complex-coding techniques and is therefore difficult to create an efficient architecture design for. This paper presents an effective method that reduces the amount of required operation significantly. Based on the computation analysis, a novel architecture was developed, which performs two main functions, IMDCT with dynamic windowing and subband Synthesis efficiently with pipeline operation. The decoder was designed based on simplicity and low-cost, while retaining the high-efficiency requirement
Reflections of a psycho-educational intern at a child protection unit : the processes and impact of engagement (2006)

Psycho-educational training programmes in South Africa currently aim to ensure that both the individual and community are benefited by trainees who graduate from these programmes. In addition, educational psychologists serving internships require training in community-oriented forms of practice. To achieve this aim, the University of Stellenbosch's Unit for Educational Psychology (UEP) follows an ecosystemic approach whereby interns perform community service at several centres in the Western Cape as part of their training programme. This article draws on the experiences of an intern at a Child Protection Unit (CPU) and the assistance given to the latter from the initial introduction to clients to the termination of therapy by the supervising psychologist. The article explores the functioning of a community-based unit such as a CPU and describes what is required of a psycho-educational intern by the Health Professions Council of South Africa (HPCSA) when working within a community context. The challenges which the intern confronted at the CPU are also indicated. Finally, conclusions and recommendations are drawn from these findings, which may prove useful to other emerging professionals working in similar community contexts.
Safety and tolerance of trospium chloride in the high dose range. (1993)

The safety and tolerance of increasing single oral doses of 20, 40, 80, 120, 180, 240 and 360 mg trospium chloride (Spasmo-lyt, CAS 10405-0204) were investigated in 29 healthy male volunteers in a double-blind placebo-controlled study. Blood pressure, heart rate, ECG, pupillary diameter, salivary secretion, and subjective reports of tolerance revealed no essential differences between placebo and trospium chloride in doses up to 120 mg. Starting with single doses of 180 mg, anticholinergic effects were observed with increasing intensity, i.e., dilatation of the pupils, reduction of salivary flow, and increase of heart rate. While the highest administered dose of 360 mg trospium chloride did not cause any relevant changes of vital parameters (blood pressure, pulse, ECG), it was subjectively rated as quite unpleasant. The data show that trospium chloride is well tolerated in single oral doses well above the current therapeutic daily dose of up to 40 mg.
The occurrence of herbicide cross-resistance in a population of annual ryegrass, <i>Lolium rigidum</i> , resistant to diclofop-methyl (1986)

A population of L. rigidum, which is known to have developed resistance to one of the diphenyl-ethertype of herbicides, diclofop-methyl, was tested for cross-resistance to three other herbicides of the same type, namely fluazifop-butyl, oxyfluorfen and the experimental herbicide CGA 82725. The population was also tested for cross-resistance to two sulfonylurea-type herbicides - chlorsulfuron and the experimental herbicide DPX-T6376. A population susceptible to diclofop-methyl was used as the controls in the tests. The two populations were treated with various rates of the herbicides during germination and at the two-leaf stage. The results show that the diclofop-methyl-resistant biotype was cross-resistant to fluazifop-butyl, CGA 82725, chlorsulfuron and DPX-T6376 but not to oxyfluorfen.
The atomic iodine photodissociation laser (1984)

After almost two decades of laboratory research and development, the iodine photodissociation laser is now a developed system with industrial and scientific applications. This article reviews the progress of the iodine laser, the basic configuration and performance of a flashlamp-pumped system, and several applications areas. The major impetus behind the development of the iodine photodissociation laser (IPL) has been the requirement for a high-power, short-pulse, terawatt laser for laser fusion studies.
Addition to inhaled corticosteroids of long-acting beta2-agonists versus anti-leukotrienes for chronic asthma (2011)

In adults with asthma that is inadequately controlled by predominantly low-dose ICS with significant bronchodilator reversibility, the addition of LABA to ICS is modestly superior to the addition of LTRA in reducing oral corticosteroid-treated exacerbations, with an absolute reduction of two percentage points. Differences favouring LABA over LTRA as adjunct therapy were observed in lung function and, to a lesser extend, in rescue medication use, symptoms and quality of life. The lower overall withdrawal rate and the higher proportion of participants satisfied with their therapy indirectly favour the combination of LABA + ICS over LTRA + ICS. Evidence showed a slightly increased risk of SAE with LABA compared with LTRA, with an absolute increase of one percentage point. Our findings modestly support the use of a single inhaler for the delivery of both LABA and low- or medium-dose ICS. Because of the paucity of paediatric trials, we are unable to draw firm conclusions about the best adjunct therapy in children.
Neutralization of interleukin-17 attenuates high fat diet-induced non-alcoholic fatty liver disease in mice (2013)

Non-alcoholic fatty liver disease (NAFLD) is hepatic manifestation of a metabolic syndrome and includes a spectrum of hepatic steatosis, steatohepatitis, and fibrosis. Interleukin-17 (IL-17) has been reported to play a critical role in inflammatory progression of some liver diseases. The present study was designed to investigate the role of IL-17 on high fat diet-induced NAFLD in C57BL/6 mice. IL-17 blockade with anti-IL-17mAb signiﬁcantly improved liver function, attenuated hepatic lipid accumulation, suppressed Kuffer cells activation, and decreased pro-inflammatory cytokines levels, which were associated with inhibition of NF-κB signaling cascades activation. Our data suggested that IL-17 was related to disease progression in NAFLD mouse model and blocking IL-17 may be a promising novel therapeutic approach for patients with NAFLD.

2‐Cyanoprop‐2‐yl dithiobenzoate mediated reversible addition–fragmentation chain transfer polymerization of acrylonitrile targeting a polymer with a higher molecular weight (2007)

Abstract The reversible addition–fragmentation chain transfer (RAFT) polymerization of acrylonitrile (AN) mediated by 2‐cyanoprop‐2‐yl dithiobenzoate was first applied to synthesize polyacrylonitrile (PAN) with a high molecular weight up to 32,800 and a polydispersity index as low as 1.29. The key to success was ascribed to the optimization of the experimental conditions to increase the fragmentation reaction efficiency of the intermediate radical. In accordance with the atom transfer radical polymerization of AN, ethylene carbonate was also a better solvent candidate for providing higher controlled/living RAFT polymerization behaviors than dimethylformamide and dimethyl sulfoxide. The various experimental parameters, including the temperature, the molar ratio of dithiobenzoate to the initiator, the molar ratio of the monomer to dithiobenzoate, the monomer concentration, and the addition of the comonomer, were varied to improve the control of the molecular weight and polydispersity index. The molecular weights of PANs were validated by gel permeation chromatography along with a universal calibration procedure and intrinsic viscosity measurements. 1 H NMR analysis confirmed the high chain‐end functionality of the resultant polymers. © 2007 Wiley Periodicals, Inc.

Differential expression of a phosphoepitope at the kinetochores of moving chromosomes (1993)

A phosphorylated epitope is differentially expressed at the kinetochores of chromosomes in mitotic cells and may be involved in regulating chromosome movement and cell cycle progression. During prophase and early prometaphase, the phosphoepitope is expressed equally among all the kinetochores. In mid-prometaphase, some chromosomes show strong labeling on both kinetochores; others exhibit weak or no labeling; while in other chromosomes, one kinetochore is intensely labeled while its sister kinetochore is unlabeled. Chromosomes moving toward the metaphase plate express the phosphoepitope strongly on the leading kinetochore but weakly on the trailing kinetochore. This is the first demonstration of a biochemical difference between the two kinetochores of a single chromosome. During metaphase and anaphase, the kinetochores are unlabeled. At metaphase, a single misaligned chromosome can inhibit further progression into anaphase. Misaligned chromosomes express the phosphoepitope strongly on both kinetochores, even when all the other chromosomes of a cell are assembled at the metaphase plate and lack expression. This phosphoepitope may be involved in regulating chromosome movement to the metaphase plate during prometaphase and may be part of a cell cycle checkpoint by which the onset of anaphase is inhibited until complete metaphase alignment is achieved.
Charge separation of triply charged ions (1989)

Abstract Formation of multiply charged ions is shown to contribute a significant fraction of the total ionization by high energy electrons, and multiple ionization is almost always followed by charge‐separation reactions. Triple ionization and subsequent dissociations can be well characterized by the electron‐three ion coincidence technique. Results obtained using this new technique are compared with computer simulations of the dissociations of OCS 3+ and SO 3+ 2 , and the initial momenta and relátive angles of all three fragments are thereby determined. Triply charged benzene ions are shown to undergo many competing charge‐separation reactions.
An object oriented model for distributed backup and archive (2002)

Compound data objects and distributed computational environments pose interesting storage management challenges. EMC is investigating a variety of approaches to meet these challenges, among which are object oriented models for archive/retrieve and backup/restore operations. This paper describes a model which is aligned with standards being developed by the OMG and X/Open. We propose that, in conjunction with innovative storage system design, such a model can lead to centralized storage management services for compound objects in a distributed environment.
Preparation of Uniform Resistivity n-Type Silicon by Nuclear Transmutation (1961)

By the capture of a thermal neutron, the natural isotope Si30 can be transmuted into the unstable isotope Si31 which decays by beta emission with a 2.62 hr half‐life to the stable isotope P31. By means of this reaction, donors can be produced in a silicon crystal. Because of the uniformity of flux which can be obtained in large nuclear reactors, this technique lends itself to the preparation of uniformly doped n‐type silicon. After irradiation the silicon crystal is heavily damaged by the emitted betas, by the recoil of the decaying Si31, and by the high energy neutrons that are unavoidably present in the reactor. However, this damage can be removed by annealing at temperatures near 600°C. The technique has been used to produce n‐type silicon with nominal resistivities between 0.1 and 20 ohm‐cm. The resistivity of the resulting crystals was uniform over dimensions of 5 cm to within ±5%.
Leonardo Padura: "cada libro que he escrito es el libro más maduro" (2009)

The current focus of many functional genomic studies is on the elucidation of gene regulatory networks. The functional analyses of transcription factors and their DNA-binding sites, in conjunction with genome-wide expression profiling, are crucial in understanding of gene regulatory networks. This paper describes an efficient and easy method for characterizing the DNA-binding sequence specificity of novel plant transcription factors. This new method is based on the fusion of a DNA-binding protein (DBP) to 6xHis-tagged cellulase D (CELD), which serves both as a means for affinity purification of DBP-DNA complex in the selection of binding sites from a pool of biotinylated random-sequence oligonucleotides and as a reporter for measurement of DNA-binding activity. Thus, it eliminates the use of radioactivity and gel electrophoresis techniques currently used for purification of DBP-DNA complexes and assays of DNA-binding activity. The effectiveness of this method was demonstrated by the success of simultaneous selection of the binding sites of nine plant DBPs from four superfamilies (AP2, bHLH, NAC and MYB). The high-throughput capacity of CELD-based DNA-binding assays allows the quantitative analysis of the binding sequence specificity from a large number of DBP-selected oligonucleotides. The binding sequence specificity of three novel transcription factors (rice OsbHLH66, wheat TaNAC69 and TaMYB80), determined with this method, is presented. This new method provides the capacity of high-throughput analysis on the DNA-binding sequence specificity of a large number of putative transcription factors, predicted on the basis of conserved DNA-binding domains.
Ristocetin-lnduced Platelet Aggregate Formation and Adherence to the Probe of an Impedance Aggregometer (1990)

The examination of the interaction between ristocetin and platelets generally is performed in an optical aggregometer where aggregate formation is detected by a change in turbidity. Ristocetin also will induce conductivity changes in an impedance aggregometer with either fresh whole blood or fresh platelet-rich plasma due to aggregate attachment to the electrical probe. Formaldehyde-fixed platelets, however, do not attach, and although fresh platelets agglutinate at extremes of pH, probe adhesion does not occur unless the pH is within a certain range. Incubation of platelet preparations with neuraminidase, colchicine, or cytochalasin-b affects neither aggregate formation nor probe adherence. Incubation of platelet preparations with a fibronectin tetrapeptide inhibitor eliminates aggregate formation in response to collagen but is without effect on ristocetin-induced attachment of aggregates to the impedance probe. It is suggested that the ability of platelet aggregates to attach to an impedance probe in response to ristocetin is dependent on additional aspects of the functional integrity of platelet preparations and that these changes required for probe adherence may have in vivo significance.
Isotope-Dilution Assay for Urinary Methylmalonic Acid in the Diagnosis of Vitamin B<sub>12</sub> Deficiency (1987)

Vitamin B12 deficiency is a frequently considered diagnosis for which there is no single, commonly available and accurate test. A urinary methylmalonic acid assay using gas chromatography-mass spectrometry has been proposed as the preferred test. We reviewed vitamin B12 assays on 1599 consecutive patients and prospectively studied all patients with low serum B12 levels (n = 75) and a random sample of patients with normal levels (n = 68). Of 96 evaluable patients, 7 had clinical deficiency. All 7 deficient patients had urinary methylmalonic acid levels greater than 5 micrograms/mg creatine (sensitivity, 100%; confidence interval, 65% to 100%). Of the 89 patients who were not clinically deficient, 88 had urinary methylmalonic acid levels less than or equal to 5 micrograms/mg creatinine (specificity, 99%). The overall test accuracy in this population was 99%. If the high sensitivity and specificity of the gas chromatography-mass spectrometry assay for urinary methylmalonic acid is supported by other clinical studies, the methylmalonic acid assay may become the reference standard for the diagnosis of vitamin B12 deficiency.

G. A. Company of Sweden, has now been in use in Australia for three years.
Effect of increasing oral doses of loperamide on gallbladder motility in man. (1990)

1. Loperamide, a peripherally acting opiate receptor agonist with antidiarrhoeal action, inhibits ileal and colonic motor function. To determine the effect of loperamide on gallbladder motility, we have pretreated five healthy volunteers with 2 mg oral loperamide 24 h, 20, 12 and 2.5 h before; six healthy volunteers with 16 mg oral loperamide 2.5 h before; and eight healthy volunteers with 16 mg oral loperamide 12 and 2.5 h before intravenous infusion of a 'physiological dose' of 12.5 pmol kg-1 cholecystokinin (CCK) for 1 h to stimulate gallbladder contraction. All subjects served as their own controls. Gallbladder volume was measured by ultrasonography and plasma CCK by radioimmunoassay until 90 min after start of the CCK infusion. 2. Infusion of CCK resulted in plasma CCK concentrations similar to those after intraduodenal fat. Integrated gallbladder contraction after 4 X 2 mg loperamide (4600 +/- 891% min) was similar to that without pretreatment (5270 +/- 1037% min; NS). Integrated gallbladder contraction after 1 X 16 mg loperamide diminished from 5458 +/- 412% min without to 2632 +/- 816% min with loperamide (P less than 0.05), and was completely abolished to -596 +/- 762% min (P less than 0.0005 vs without loperamide) after 2 X 16 mg loperamide. 3. It is concluded that loperamide inhibits gallbladder contraction in response to a physiological dose of cholecystokinin in a dose-dependent manner.
Parallel lossless data compression using the Burrows-Wheeler Transform (2008)

In this paper, we present parallel algorithms for lossless data compression based on the Burrows-Wheeler Transform (BWT) block-sorting technique. We investigate the performance of using data parallelism and task parallelism for both multi-threaded and message-passing programming. The output produced by the parallel algorithms is fully compatible with their sequential counterparts. To balance the workload among processors we develop a task scheduling strategy. An extensive set of experiments is performed with a shared memory NUMA system using up to 120 processors and on a distributed memory cluster using up to 100 processors. Our experimental results show that significant speedup can be achieved with both data parallel and task parallel methodologies. These algorithms will greatly reduce the amount of time it takes to compress large amounts of data while the compressed data remains in a form that users without access to multiple processor systems can still use.

Utility-based On-demand Heuristic Strategy to Grid Computing (2005)

Grids aim at exploiting synergies that result from cooperation of autonomous distributed entities. For this cooperation to be sustainable, participants need to have economic incentive. Within service-oriented Grids, resources may be advertised and traded as services, and QoS requirement is the most important attribute. In this paper, we build on two intellectual threads: market-based approaches and the economic theory of utility to resource allocation. We consider the problem of task scheduling subject to time and budget constrains as QoS-aware joint utility function, and scheduling object is to maximize total attained utility. This scheduling problem can be shown to be NP-hard, thus we present a utility-driven heuristic scheduling algorithm (UDS) for this problem. We study the performance of UDS algorithm through a stochastic Petri net (SPN) model. In the end, the performance of model is analyzed by SPNP software package. The numerical results show that UDS can guarantee QoS for users
