An experimental study of nozzle diameters, aeration depths and angles on standard aeration efficiency (SAE) in a venturi aerator (2009)

A 1.1 kW submersible water pump with a venturi air injector was used in this study to examine the effects of three factors including nozzle diameter (14, 17 and 20 mm), aeration depth (20, 40 and 60 cm), and aeration angle (0, 22.5 and 45°) on standard aeration efficiency (SAE). For maximum air entrainment, HT / DT ratio and DT / DN ratio were equal to zero and 2, respectively. Among the first factor experiments, 14 mm nozzle diameter showed the highest SAE value (P&lt;0.05). Although, 60 cm aeration depth and 45° aeration angle had more SAE value among other depths and angles, but there was not a significant difference (P&gt;0.05) in each aeration depths and angles. Only, the determination coefficient for effect of nozzle diameters on SAE value showed a good result (R2= 0.958). The greatest oxygen transfer efficiency in this study has been achieved with using 14 mm nozzle size, 60 cm depth of aeration, and 45° angle of venturi tube in water aeration that was 1.166 kgO2/ kWh. Venturi aerators are very inexpensive in comparison with other aerators and have some other advantages that can be considered as one of the best devices for water aeration.
VALUE OF IODIZED OIL, 40 PER CENT, IN THE DIAGNOSIS OF PULMONARY INFECTIONS (1927)

My interest in diagnosis by the use of iodized oil, 40 per cent, while of course general, has been centered in particular on its value in tuberculous cases: on the one hand, in order to show more clearly than might be possible by physical examination or the ordinary roentgen-ray examination, the pathologic condition in a lung previous to a proposed thoracoplasty; on the other hand, to show the condition in the lung which might explain a lack of complete success years after a thoracoplasty. In addition I shall report a few cases illustrative of its value to the surgeon in nontuberculous lesions. <h3>REPORT OF CASES</h3><h3>Case 1.</h3> —C. R., a man, who had had tuberculosis since 1919, with repeated pulmonary hemorrhages, had had a thoracoplasty performed two years previously but an incomplete one, the first and second and the tenth and eleventh ribs having been left intact. He had improved
Relationships Between Intracellular Calcium and Afterhyperpolarizations in Neocortical Pyramidal Neurons (2004)

We examined the effects of recent discharge activity on [Ca2+]i in neocortical pyramidal cells. Our data confirm and extend the observation that there is a linear relationship between plateau [Ca2+]i and firing frequency in soma and proximal apical dendrites. The rise in [Ca2+] activates K+ channels underlying the afterhyperpolarization (AHP), which consists of 2 Ca(2+)-dependent components: the medium AHP (mAHP) and the slow AHP (sAHP). The mAHP is blocked by apamin, indicating involvement of SK-type Ca(2+)-dependent K+ channels. The identity of the apamin-insensitive sAHP channel is unknown. We compared the sAHP and the mAHP with regard to: 1) number and frequency of spikes versus AHP amplitude; 2) number and frequency of spikes versus [Ca2+]i; 3) IAHP versus [Ca2+]i. Our data suggest that sAHP channels require an elevation of [Ca2+]i in the cytoplasm, rather than at the membrane, consistent with a role for a cytoplasmic intermediate between Ca2+ and the K+ channels. The mAHP channels appear to respond to a restricted Ca2+ domain.
Experimental investigation of cocurrent two‐phase flow in a vertical rectangular channel (1987)

Abstract New time averaged data of two‐phase flow in bubbly and slug regimes are presented. A modified dual spherical tipped optical fiber probe is used to measure local void fractions, gas velocity and bubble sizes. Hot film anemometry was used to measure the local mean liquid velocity axially. The void fraction, gas and liquid velocities values were presented as averages over the long and short dimensions respectively. Also core values of these variables are presented along the smaller dimension of 12.7 mm, near the plane of symmetry of the longer dimension, to show the most general trend of the different bubbly and slug flow runs. Bubble sizes obtained experimentally were compared with predictive models applied to circular geometries and were found to have a reasonable agreement. It was also interesting to find that local void fractions measured using hot film anemometers were comparable to those found by optical fiber probes. Frequencies of interfacial passage of bubbles and slugs are presented which show rather flat profiles across the channel. It is hoped that these data can be further used in predictive two‐phase two‐fluid models in the future. Lastly of interest is the fact that slip values near the boundaries were shown to be less than 1.0 for some cases in bubbly flow similar to those observed in circular geometries.
Silencing of cytosolic NADP<sup>+</sup>-dependent isocitrate dehydrogenase by small interfering RNA enhances the sensitivity of HeLa cells toward staurosporine (2009)

Staurosporine induces the production of reactive oxygen species, which play an important causative role in apoptotic cell death. Recently, it was demonstrated that the control of cellular redox balance and the defense against oxidative damage is one of the primary functions of cytosolic NADP(+)-dependent isocitrate dehydrogenase (IDPc) by supplying NADPH for antioxidant systems. The present report shows that silencing of IDPc expression in HeLa cells greatly enhances apoptosis induced by staurosporine. Transfection of HeLa cells with an IDPc small interfering RNA (siRNA) markedly decreased activity of IDPc, enhancing the susceptibility of staurosporine-induced apoptosis reflected by DNA fragmentation, cellular redox status and the modulation of apoptotic marker proteins. These results indicate that IDPc may play an important role in regulating the apoptosis induced by staurosporine and the sensitizing effect of IDPc siRNA on the apoptotic cell death of HeLa cells offers the possibility of developing a modifier of cancer chemotherapy.
Impact of renal denervation on renalase expression in adult rats with spontaneous hypertension (2012)

The aim of this study was to investigate the impact of renal denervation on the blood pressure, plasma renalase content and expression of renalase and tyrosine hydroxylase (TH) in the kidney of spontaneous hypertensive (SH) rats and to explore the mechanism of renal denervation involved in lowering blood pressure. SH rats (n=48) were randomly assigned to baseline, surgery (renal denervation), sham and control groups. WKY rats matched in age (n=12) served as the baseline control group. All rats were housed until they were 12 weeks old. The rats in the baseline group and the WKY group rats were sacrificed, and blood and kidney were collected for examination. In the renal denervation, sham and control groups, the blood pressure was continuously monitored. One and six weeks after renal denervation, 6 rats in each group were sacrificed, and blood and kidney were collected for examination. ELISA was employed to measure the plasma renalase, and western blot analysis was performed to detect the expression of TH and renalase in the kidney. Compared with the WKY rats, SH rats in the baseline group had significantly increased blood pressure and markedly elevated TH protein expression (P<0.05), but dramatically reduced plasma renalase content and protein expression of renalase in the kidney (P<0.05). One week after surgery, the mean arterial pressure and TH protein expression in the surgery group was lowered compared with the baseline group and dramatically reduced when compared with the sham and control groups (P<0.05). In the surgery group, renalase levels were markedly increased compared with the baseline, sham and control groups (P<0.05). Six weeks after renal denervation, the mean arterial pressure and TH levels in the surgery group were significantly increased while the renalase content and expression were markedly reduced compared with those at week 1, however, there were no marked differences among the surgery, sham and control groups (P>0.05). Moreover, no pronounced differences in the above variables were found between the sham and control groups at any timepoint (P>0.05). Renal denervation can lower blood pressure, which may be attributed to the suppression of sympathetic nerves, increase in plasma renalase content and renalase expression in the kidney.

A Spermatozoa-Associated Factor Regulates Proenkephalin Gene Expression in the Rat Epididymis (1990)

The gene encoding the opioid peptide precursor preproenkephalin is expressed at high levels in the initial segment of the adult rat epididymis. Expression is localized to principal cells, the secretory epithelial cells lining the epididymal duct. During development, epididymal proenkephalin mRNA levels show a pronounced increase at about 44 days of age, coincident with the initial entry of spermatozoa into the epididymal lumen. Hypophysectomy leads to a 60-fold decrease in epididymal proenkephalin mRNA levels. Testosterone replacement can prevent this decline in a manner consistent with an effect upon spermatogenesis. Castration studies demonstrate that a gonadal factor other than testosterone directly regulates epididymal proenkephalin expression, and the results of efferent duct ligation suggest that this factor must be supplied through an intact connection of the testis and epididymis. Proenkephalin mRNA levels in the epididymis correlate with the decline and reappearance of spermatozoa induced by the alkylating agent busulphan. Thus, the developmental profile of proenkephalin expression, coupled with the results of both surgical and pharmacological manipulations of the reproductive tract, indicate that spermatozoa, or a spermatozoa-associated factor, regulate proenkephalin gene expression in the epididymis.
Combining Global and Local Optimization Techniques for Automatic History Matching Production and Seismic Data (2001)

Abstract Gradient based optimization techniques in computer-aided history matching are increasingly adopted by oil industries, because of the great time saving they can offer over conventional trial and error approaches. However, these methods lead to the identification of a single set of parameters, thus neglecting the inherent non-uniqueness of the solution of the underlying inverse problem. In this paper we propose a new approach that couple a chaotic sampling of parameter space with a local minimization technique. The first step is effected evolving a non-linear dynamical system, by which we identify several points to be successively used as initial guesses for a local, gradient based, optimizer. This provides a series of alternative matched models, with different production forecasts, that improve the understanding of the possible reservoir behaviors. The validity of this approach has been proven on a synthetic reservoir derived from a real West Africa field.
Schizophrenia Researchers Striving for Early Detection and Intervention (1999)

SANTA FE, NM—Can early treatment, preferably begun even before psychotic symptoms emerge, improve long-term outcomes for people with schizophrenia? That hope, according to researchers presenting new findings last month at the International Congress on Schizophrenia, is sparking efforts to identify early signs of the disease in high-risk individuals and to develop interventions aimed at delaying its onset or reducing its severity.
Guideline Development for Technological Interventions for Children and Young People to Self-Manage Attention Deficit Hyperactivity Disorder: Realist Evaluation (2019)

Complex intervention development for complex populations such as CAYP with ADHD should adopt methods such as RE, to account for the context it is delivered in, and co-design, which involves developing the intervention in partnership with key stakeholders to increase the likelihood that the intervention will succeed. The development of the guidelines outlined in this paper could be used for the future development of technologies that aim to facilitate self-management in CAYP with ADHD.

Characterization of the Volatile Profile of Brazilian Moscatel Sparkling Wines Through Solid Phase Microextraction and Gas Chromatography (2015)

Solid phase microextraction, one-dimensional gas chromatography (1D-GC) and comprehensive two-dimensional gas chromatography (GC×GC) with mass spectrometric detector have been used to characterize the volatile profile of Moscatel sparkling wines.Predominant classes were esters, acids, alcohols and terpenes.The efficiency of GC×GC was apparent due to the higher number of compounds positively and/or tentatively identified through this technique (two and a half times higher than with 1D-GC), as well as by the separation of co-eluted compounds in 1D-GC.Principal components analysis showed that the volatile profile of the majority of sparkling wines is similar.Only two samples differed from others and the compounds responsible for this behavior were nerol, menthol, linalool acetate, limonene and geraniol.Furthermore, a clear separation among sparkling wines done with two Moscato grape varieties (Bianco and Giallo) was observed in cluster analysis due to the higher chromatographic area of terpenes and norisoprenoids verified in Giallo samples.
Fast codevector search scheme for 3D mesh model vector quantisation (2008)

A new fast approach to the nearest codevector search for 3D mesh compression using an orthonormal transformed codebook is proposed. The algorithm uses the coefficients of an input vector along a set of orthonormal bases as the criteria to reject impossible codevectors. Compared to the full search algorithm, a great deal of computational time is saved without extra distortion and additional storage requirement. Simulation results demonstrate the effectiveness of the proposed algorithm in terms of computational complexity.

[Embolization in the therapy of hemoptysis. The results of a combination of Spongostan/sclerosing drugs and the role of electrocoagulation]. (1989)

The author's purpose was to evaluate the efficacy of therapeutic embolization in pulmonary hemorrhage performed with fibrin foam (Spongostan) suspended in sclerosing agents (hydroxy-polyethoxy-dodecane 3%, or natrium morruate 5%), and electrocoagulation (Biotrol, spa) as an alternative to surgery. Twenty patients were embolized: 17 with fibrin foam and sclerosing agents only, 2 with the addition of electrocoagulation and a Gianturco coil respectively, and 1 with electrocoagulation alone. The follow-up ranges from 3 to 42 months (average 22). A patient affected by aspergilloma died a few days after hemoptysis. The patient treated by electrocoagulation alone suffers from periodical hematic expectoration (spitting). The remaining 18 patients have not shown any pathological findings. In 2 cases the arterial occlusion was confirmed by angiography, while in 1 case partial arterial recanalization was observed. Such a finding was due to the vessel dimensions and to hyperflux values. In similar cases, obstruction must be completed by different techniques (e.g. Gianturco coils, electrocoagulation, detachable balloons, etc.). The absence of flux resulting from embolization improves electrocoagulation efficiency, which should be considered as the technique of choice. Even though additional trials are needed, the techniques have proven quite reliable and suitable to replace surgery in low-aggression lesions.
FUNCTIONAL POLYHYDROXYALKANOATES SYNTHESIZED BY MICROORGANISMS (2000)

Many bacteria have been found to synthesize a family of polyesters termed polyhydroxyalkanoate, abbreviated asPHA. Some interesting physical properties of PHAs such as piezoelectricity, non-linear optical activity, biocompatibility andbiodegradability offer promising applications in areas such as degradable packaging, tissue engineering and drag delivery.Over 90 PHAs with various structure variations have been reported and the number is still increasing. The mechanicalproperty of PHAs changes from brittle to flexible to elastic, depending on the side-chainlength of PHA. Many attempts havebeen made to produce PHAs as biodegradable plastics using various microorganisms obtained from screening naturalenvironments, genetic engineering and mutation. Due to the high production cost, PHAs still can not compete with the non-degradable plastics, such as polyethylene and polypropylene. Various processes have been developed using low cost rawmaterials for fermentation and an inorganic extraction process tbr PHA purification. However, a super PHA production strainmay play the most critical role for any large-scale PHA production. Our recent study showed that PHA synthesis is acommon phenomenon among bacteria inhabiting various locations, especially oil-contaminated soils. This is very importantfor finding a suitable bacterial strain for PHA production. In fact, PHA production strains capable of rapid growth and rapidPHA synthesis on cheap molasses substrate have been found on molasses contaminated soils. A combination of novelproperties and lower cost will allow easier commercialization of PHA for many applications.
Bug Reports Prioritization: Which Features and Classifier to Use? (2013)

Large open source bug tracking systems receives large number of bug reports daily. Managing these huge numbers of incoming bug reports is a challenging task. Dealing with these reports manually consumes time and resources which leads to delaying the resolution of important bugs which are crucial and need to be identified and resolved earlier. Bug triaging is an important process in software maintenance. Some bugs are important and need to be fixed right away, whereas others are minor and their fixes could be postponed until resources are available. Most automatic bug assignment approaches do not take the priority of bug reports in their consideration. Assigning bug reports based on their priority may play an important role in enhancing the bug triaging process. In this paper, we present an approach to predict the priority of a reported bug using different machine learning algorithms namely Naive Bayes, Decision Trees, and Random Forest. We also investigate the effect of using two feature sets on the classification accuracy. We conduct experimental evaluation using open-source projects namely Eclipse and Fire fox. The experimental evaluation shows that the proposed approach is feasible in predicting the priority of bug reports. It also shows that feature-set-2 outperformsfeature-set-1. Moreover, both Random Forests and Decision Trees outperform Naive Bayes.
Learner Modeling Using Educational Games: A Review of the Literature (2015)

Recently, there has been growing interest in the use of games in education. Educational games have been found to stimulate learners by increasing their motivation and engagement. In addition, educational games could be used for creating the learner model. In fact, these games provide ample opportunities for learner’s interactions with the computer which can be exploited for creating a reliable learner model. This papera presents a survey of the field of learner modeling using educational games, describing the main methods and proposing taxonomy to better organize them. The paper also enumerates several educational games that are suitable for experimentation. This synthesis is expected to not only help the researchers and developers working in this field but also pedagogues and teachers who plan to integrate these approaches in educational context.
Stabilized α-Sn grown at high temperature by molecular beam epitaxy (1994)

The first observation of lattice images of stabilized α-Sn grown at 150 °C by high-resolution transmission electron microscopy is reported here. A structure of CdTe/α-Sn/InSb has been grown on an InSb buffer layer, which was grown on an InSb(100) substrate by molecular beam epitaxy at 220 °C. During the growth, cross doping was carefully avoided. In addition, by the energy-dispersive x-ray spectroscopy, it was found that the interdiffusion of In and Te, which usually occurs across the interface of CdTe/InSb, is prevented by the α-Sn layer inserted at the interface.
