PROBLEMS IN DEFINING SYNERGISTS AND INHIBITORS OF THE ORIENTAL FRUIT MOTH PHEROMONE BY FIELD EXPERIMENTATION (1974)

The influence of dodecyl acetate on the response of male Grapholitha molesta to pheromone sources was observed under field conditions. Males were not trapped at live virgin female or synthetic pheromone sources when dodecyl acetate was present in the same trap or within 15 cm of the bait. Capture rate was still reduced at 30 cm separation but not at 60 cm. When dodecyl acetate was present as a background odour over a large area, catches of males at pheromone traps increased significantly. Reasons for these results remain obscure but the findings show that care is needed in the evaluation for possible control purposes of compounds which modify male sexual activity. Résumé PROBLÈMES RENCONTRÉS POUR DÉFINIR LES SUBSTANCES SYNERGISTES OU INHIBITRICES DE LA RÉPONSE DE GRAPHOLITHA MOLESTA ( ORIENTAL FRUIT MOTH ) À SA PHÉROMONE SEXUELLE L'influence du dodecyl acetate sur la réponse du mâle de Grapholitha molesta a éTÉ étudiée dans des conditions naturelles. Des pièges attractifs, appâTÉs avec une femelle vierge ou avec sa phéromone de synthèse, ne capturent aucun mâle quand du dodecyl acetate est placé simultanément dans ces pièges ou à une distance de 15 cms de ceux‐ci. Quand ce produit est placé à 30 cms du piège on observe encore une réduction du taux de capture, mais l'influence est nulle pour une distance de 60 cms. Quand du dodecyl acetate est utilisé sur une très grande surface, comme odeur de fond, les captures de mâles dans les pièges à phéromone augmentent de faĉon significative. Ces résultats sont difficiles à expliquer, mais ils montrent que l'on doit prendre beaucoup de précautions avant d'évaluer, en vue d'applications éventuelles, l'inTÉrêt à utiliser des composés qui modifient l'activiTÉ sexuelle des mâles.
Time Independent Query Recommendations Using Concept Based User Profile from Search Engine Query Logs (2014)

2 Abstract: Search engines are highly confided resources of the people in mustering web information or obtaining relevant data approached for. The query log file contains an entry for every request posed by the user to the search engine and it is maintained in the system desktop or in the proxy server. Query log mining improves the performance of the search engine. The proposed algorithm mines the query log file which discovers the similar query keywords, URLs and the concepts based on both positive and negative preferences in its first phase. In the Second phase, the query cluster and the URL cluster is generated by using the combined similarity measure generated from the first phase. The cluster recommends the query to the user to frame their future queries based on their previous search histories and click through data. Expert's Query keyword and feedback are also considered for providing the recommendations. This approach also recommends the URLs to the user to be selected for their future queries.

Evaluation of opening bus lanes for private traffic triggered via V2X communication (2011)

Within the EC project “iTETRIS”, an architecture for simulating traffic management applications based on vehicular communications (V2X) was designed and implemented. The work was based on evaluating the needs of a real city - the city of Bologna. Applications which try to solve the detected problems were defined and evaluated in subsequent steps. This report describes the evaluation of one of the developed applications, namely “Bus Lane Management”. It was analyzed whether it is possible to detect the traffic demand via V2X communication and open bus lanes for private vehicles. It turned out that this could be done efficiently: dedicating the free space on the bus lanes improves the average travel times and route lengths of all vehicles. However, this is true only if the penetration rates stay well below 50%. If more vehicles try to benefit, the situation deteriorates readily.
Age differences in feedback reactions: The roles of employee feedback orientation on social awareness and utility. (2014)

Organizations worldwide are currently experiencing shifts in the age composition of their workforces. The workforce is aging and becoming increasingly age-diverse, suggesting that organizational researchers and practitioners need to better understand how age differences may manifest in the workplace and the implications for human resource practice. Integrating socioemotional selectivity theory with the performance feedback literature and using a time-lagged design, the current study examined age differences in moderating the relationships between the characteristics of performance feedback and employee reactions to the feedback event. The results suggest that older workers had higher levels of feedback orientation on social awareness, but lower levels of feedback orientation on utility than younger workers. Furthermore, the positive associations between favorability of feedback and feedback delivery and feedback reactions were stronger for older workers than for younger workers, whereas the positive association between feedback quality and feedback reactions was stronger for younger workers than for older workers. Finally, the current study revealed that age-related differences in employee feedback orientation could explain the different patterns of relationships between feedback characteristics and feedback reactions across older and younger workers. These findings have both theoretical and practical implications for building theory about workplace aging and improving ways that performance feedback is managed across employees from diverse age groups.
Autophagy: Basic Principles and Relevance to Disease (2008)

Autophagy is a process by which cytoplasmic components are sequestered in double membrane vesicles and degraded upon fusion with lysosomal compartments. In yeast, autophagy is activated in response to changes in the extracellular milieu. Depending upon the stimulus, autophagy can degrade cytoplasmic contents nonspecifically or can target the degradation of specific cellular components. Both of these have been adopted in higher eukaryotes and account for the expanding role of autophagy in various cellular processes, as well as contribute to the variation in cellular outcomes after induction of autophagy. In some cases, autophagy appears to be an adaptive response, whereas under other circumstances it is involved in cell death. In mammals, autophagy has been implicated in either the pathogenesis or response to a wide variety of diseases, including neurodegenerative disease, chronic bacterial and viral infections, atherosclerosis, and cancer. As the basic molecular pathways that regulate autophagy are elucidated, the relationship of autophagy to the pathogenesis of various disease states emerges.
Power control leased on bit error rate (BER) measurements (2002)

We consider power control for the reverse link of a DS/CDMA system where received powers are to be controlled to achieve specified BERs for individual users, not necessarily the same. Our emphasis is to work with bit error rates (BERs), which are more readily measurable than the signal to interference ratios (SIRs), which received a lot of attention in the literature. The power control algorithm that we propose works without knowledge of the relationship between the BER and the SIR. The convergence of this algorithm is shown for a general class of expressions for the BER encountered in digital communications.
Isolation and Synthesis of a New Aromatic Compound, Brefelamide, from <i>Dictyostelium</i> Cellular Slime Molds and Its Inhibitory Effect on the Proliferation of Astrocytoma Cells (2005)

[structure: see text] We have explored the diversity of secondary metabolites produced by cellular slime molds to examine the possible use of such cellular slime molds as a resource for novel drug development. A new aromatic amide, brefelamide (1), was isolated from methanol extracts of the fruiting bodies of Dictyostelium brefeldianum and D. giganteum. The structure of 1 was determined by spectral means including EIMS and (1)H and (13)C NMR. The total synthesis of 1 was carried out to confirm the structure and obtain sufficient samples for performing biological evaluation. Interestingly, compound 1 inhibited the cellular proliferation of 1321N1 human astrocytoma cells.
Eglin-c, a polypeptide derived from the medicinal leech, prevents human neutrophil elastase-induced emphysema and bronchial secretory cell metaplasia in the hamster. (1985)

Eglin-c (Eg-c), a polypeptide with a molecular mass of 8,100 daltons, was purified from the medicinal leech Hirudo medicinalis. The Eg-c was tritiated by reductive methylation for in vitro studies. Incubation of 2.1 X 10(-10) moles of human neutrophil elastase (HNE) with 3H-elastin in the presence of 8.2 X 10(-10) moles of 3H-Eg-c inhibited 98.7% of the elastolytic activity of the enzyme. Using Sephadex G 100 chromatography and 1.7 moles of 3H-Eg-c per mole of HNE, a 34,000-dalton complex (3H-Eg-c-HNE) was observed. The stability of the complex formed between 3H-Eg-c and HNE that had been inactivated with succinyl-ala2-pro-val CH2Cl was much less than that of the 3H-Eg-c-HNE complex. In vivo studies were carried out in weight-matched groups of anesthetized golden Syrian hamsters given 100, 300, 500, or 2,000 micrograms of Eg-c in 0.5 ml saline intratracheally 1 h before 300 micrograms HNE was administered intratracheally. Control animals received saline followed by HNE or 2 doses of saline 1 h apart. Eight weeks later, lung statics and dynamics were measured in anesthetized animals, followed by histologic study of lung parenchyma and the mucosa of the large intrapulmonary airways. There were no deaths, and final mean body weights were similar in all groups.(ABSTRACT TRUNCATED AT 250 WORDS)
Hyaluronan â€“ A Functional and Structural Sweet Spot in the Tissue Microenvironment (2015)

Transition from homeostatic to reactive matrix remodeling is a fundamental adaptive tissue response to injury, inflammatory disease, fibrosis, and cancer. Alterations in architecture, physical properties, and matrix composition result in changes in biomechanical and biochemical cellular signaling. The dynamics of pericellular and extracellular matrices, including matrix protein, proteoglycan, and glycosaminoglycan modification are continually emerging as essential regulatory mechanisms underlying cellular and tissue function. Nevertheless, the impact of matrix organization on inflammation and immunity in particular and the consequent effects on tissue healing and disease outcome are arguably under-studied aspects of adaptive stress responses. Herein, we review how the predominant glycosaminoglycan hyaluronan (HA) contributes to the structure and function of the tissue microenvironment. Specifically, we examine the evidence of HA degradation and the generation of biologically active smaller HA fragments in pathological settings in vivo. We discuss how HA fragments versus nascent HA via alternate receptor-mediated signaling influence inflammatory cell recruitment and differentiation, resident cell activation, as well as tumor growth, survival, and metastasis. Finally, we discuss how HA fragmentation impacts restoration of normal tissue function and pathological outcomes in disease.
Various aspects of the scaling problem in optimization- based computer-aided design (1982)

It is now well known that a large number of engineering design problems can be viewed as mathematical programming problems, where some cost has to be minimized subject to various types of constraints. In the last few years, semi-infinite programming in particular has occupied an increasingly important position. The typical semi-infinite programming problem can be written as follows: min{f(x)|gi(x) ⩽ 0, j=1,2 ..., m, (P) ϕj(x, ω) ⩽ 0 ωεΩj, j=1,2, ..., l}
Development of a plasmid-based expression system in Clostridium thermocellum and its use to screen heterologous expression of bifunctional alcohol dehydrogenases (adhEs) (2016)

<i>Clostridium thermocellum</i> is a promising candidate for ethanol production from cellulosic biomass, but requires metabolic engineering to improve ethanol yield. A key gene in the ethanol production pathway is the bifunctional aldehyde and alcohol dehydrogenase, <i>adhE</i>. To explore the effects of overexpressing wild-type, mutant, and exogenous <i>adhE</i>s, we developed a new expression plasmid, pDGO144, that exhibited improved transformation efficiency and better gene expression than its predecessor, pDGO-66. This new expression plasmid will allow for many other metabolic engineering and basic research efforts in <i>C. thermocellum</i>. As proof of concept, we used this plasmid to express 12 different <i>adhE</i> genes (both wild type and mutant) from several organisms. Ethanol production varied between clones immediately after transformation, but tended to converge to a single value after several rounds of serial transfer. The previously described mutant <i>C. thermocellum</i> D494G <i>adhE</i> gave the best ethanol production, which is consistent with previously published results.
Gas Chromatography of Aluminum, Gallium, and Indium β-Diketone Chelates (1971)

Abstract The gas-chromatographic behavior of aluminum(III), gallium(III), and indium(III) chelates with various β-diketones was investigated. The β-diketones studied were acetylacetone and 8 synthesized, alkyl-substituted acetylacetones, benzoylacetone, dibenzoylmethane, trifluoroacetylacetone and its 5 synthesized alkyl derivatives, hexafluoroacetylacetone, benzoyltrifluoroacetone, furoyltrifluoroacetone, and thenoyltrifluoroacetone. The trifluoromethyl group increases the volatility of the chelates, while the aromatic group tends to decrease the volatility. In the alkyl-substituted acetylacetone series, the retention time of the chelates increases with an increase in the molecular weight, but it does not depend upon the volatility. On the other hand, the retention of the chelates containing the trifluoromethyl group is almost inversely correlated with the volatility.
Electroformed Nanocrystalline Coatings: An Advanced Alternative to Hard Chrome Electroplating (2003)

Abstract : This report is prepared as the final report for SERDP Project PP-1152, Electroformed Nanocrystalline Coatings: An Advanced Alternative to Hard Chrome Electroplating. The purpose of the project is to develop an environmentally benign, cost-effective replacement for hard chrome to be applied to non-line-of-sight-surfaces. The project incorporates electrodeposited nanocrystalline technology that produces materials with comparable performance to hard chrome. The report is organized into activities associated with Phases II and III of the project. Phase II optimizes the coating process and Phase III extends the process to complex internal diameter shapes. For each activity, the developmental process followed and experimental results obtained are presented. A summary of the process developed and current performance of the material as compared to hard chrome is presented. In Phase I, three different alloy coatings were synthesized on a laboratory scale utilizing a designed experimental approach on the basis of previously developed intellectual property . Binary alloys, Co-P and Co-Mo, were produced along with the ternary alloy, Co-Fe-P. These alloys were evaluated for grain size, hardness, coating thickness and thermal stability. Phase I also included effort to establish baseline emission, chemical waste production and process cost data. In Phase II, a nanocrystalline cobalt-phosphorus alloy and associated process has been established, studied and optimized. Performance tests have been conducted on uncoated and coated samples (as well as reference materials) to establish properties and performance. As part of Phase III, the nanocrystalline cobalt-phosphorus alloy coating was applied to internal diameter surfaces. Anode selection and plating parameters were selected and tested on mock-ups designed to simulate the typical internal diameter surfaces encountered in DOD applications.
Hydrogen production from continuous fermentation of xylose during growth of <i>Clostridium</i> sp. strain No. 2 (1995)

Experimental conditions are presented for continuous fermentation of xylose and glucose to hydrogen (H 2 ), using Clostridium sp. strain No. 2 growing in 300 mL of culture containing 0.3% substrate, either without pH control or with the pH controlled at 6.0. The H 2 production rate increased in proportion to increasing dilution rate within the range of about 0.4 to 1.0 h −1 . The maximal H 2 production rates of 21.03 and 20.40 mmol∙h −1 ∙L −1 were obtained from xylose and glucose with dilution rates of 0.96 and 1.16 h −1 , respectively, at pH 6.0. About 2.06 mol H 2 with a dilution rate of 0.21 h −1 at pH 6.0 and 2.36 mol H 2 with a dilution rate of 0.18 h −1 were formed per mole of xylose and glucose consumed, respectively, at uncontrolled pH.Key words: hydrogen production, continuous fermentation, xylose, Clostridium sp. strain no. 2.
Antimicrobial peptides as microbicidal contraceptives: prophecies for prophylactics – a mini review (2005)

The global increase in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and sexually transmitted infections (STIs) has led to the introduction of barrier methods, such as condoms. However, drawbacks associated with condoms, such as men being reluctant to use them and women being unable to negotiate their use, have led to the search for better and acceptable alternatives, namely the microbicides. These are gel formulations that, when used prior to sexual intercourse, protect against the transmission of HIV and other STIs. However, after observing the side-effects of nonoxynol-9, a component of the microbicidal formulations available on the market, the focus has shifted to natural available compounds demonstrating the preferred protective effects. Antimicrobial peptides (AMPs) are one such group of compounds present in a wide range of organisms from bacteria to humans. The existing 750 or so, low-molecular-weight, cationic charged peptides are classified into five major groups based on their three-dimensional structure obtained by nuclear magnetic resonance studies. The hypothesized mode of action seems to be the interaction of the positively charged peptides with the negatively charged phospholipids present on the surface of the cell membrane. Various studies have demonstrated the effect of several AMPs, namely, defensins, protegrins, cathelicidins, cecropins, polyphemusins, magainins and melittins, against various STI-causing pathogens and HIV/herpes simplex virus, both in vitro and in vivo. The contraceptive efficacies of magainin and nisin in vitro and in vivo are worth mentioning. We believe these peptides are suitable candidates in the development of newer mechanism-based microbicides in future.

Codesign system performance based on memory configurations (2003)

In the codesign methodology, the system specification is partitioned into hardware and software subsystems. Subsequently the former is synthesised into custom hardware, while the latter is compiled into processor code. A common target architecture is based on a shared bus uing a single-port global memory. Therefore, the system performance is compromised by bus contention. The hardware and software subsystems communicate through either a busy-wait or an interrupt mechanism. This paper presents two alternatives for memory configuration: one uses a dual-port memory to substitute the original single-port shared memory of the target architecture and the other uses a cache memory for the hardware subsystem, while keeping the single-port shared memory. The dual-port memory configuration aims to avoid to contention, whereas the cache memory configuration aims to reduce bus contention during the hardware subsystem memory accesses. The objective of this study is to achieve an acceptable performance in terms of the overall execution time of an application.

Ascorbic Acid in Mesencephalic Cultures: Effects on Dopaminergic Neuron Development (1991)

Ascorbic acid exists in high intracellular concentrations in fetal rat brain. In mesencephalic cultures the cellular ascorbic acid content drops sharply to undetectable levels when no ascorbic acid is added to the medium, thus creating a model of scorbutic neuronal tissue and affording the study of ascorbic acid's effects on mesencephalic cell development and function. Cultures treated with 0.2 mM ascorbic acid were compared with controls (scorbutic cultures) by using morphological and biochemical indices. Ascorbic acid cultures at 7 and 14 days in vitro showed a marked increase in glial proliferation on glial fibrillary acidic protein staining and increased neurite growth and number on tyrosine hydroxylase staining. Significantly higher dopamine uptake and levels of dopamine and 3,4-dihydroxyphenylacetic acid were also observed after 7 and 14 days of ascorbic acid treatment. The capacity to accumulate ascorbic acid and the ability to retain the intracellular ascorbic acid developed gradually as the cultures matured. Ascorbic acid reached the embryonal levels by day 14 in vitro. We conclude that although neuronal cultures can survive and grow in the absence of detectable levels of ascorbic acid, its presence exerts a broad effect on dopamine neuron morphology and biochemical functioning either directly or through increased glial proliferation, or possibly both.
