Cone and plate rheometer for polymer melts (1968)

This instrument will measure the viscosity and elasticity of polymer melts over the shear rate range 10−3 - 1 s−1 at temperatures up to 300°C. The system is driven by ten synchronous motors and torque values are measured by a transducer. Use of this principle makes it possible to fit separate heaters in the cone and the plate, so improving greatly the temperature uniformity in the sample. Illustrative results for polythene and poly (methyl methacrylate) show good agreement with viscosity measurements at high shear rates made by the complementary technique of capillary viscometry. Time-dependent behaviour is briefly discussed.
Performance Characterization of the Servioticy API: An IoT-as-a-Service Data Management Platform (2015)

In the last years, Internet of Things (IoT) and Big Data platforms are clearly converging in terms of technologies, problems and approaches. IoT workloads generate a vast amount of data that needs to be stored and processed, becoming a Big Data problem. IoT devices and sensors generate streams of data across a diversity of locations and protocols that in the end reach a central platform that is used to store and process these streams. Processing can be done in real time, with transformations and enrichment happening on-the-fly, but it can also happen after data is stored and organized in repositories. In the former case, stream processing technologies are required to operate on the data, in the latter analytics and queries are of common use. This paper presents a detailed characterization of the servIoTicy platform: a state-of-the-art infrastructure for hosting Internet of Things (IoT) workloads in the Cloud. It provides multi-tenant data stream processing capabilities, a REST API, data analytics, advanced queries and multi-protocol support in a combination of advanced data-centric technologies. The deployment of such a complex platform in the cloud requires a detailed understanding of all these components and tiers to allow for auto-scaling and dynamic provisioning capabilities. This paper aims to provide this initial characterization to be the basis for advanced cloud provisioning strategies and algorithms.

Electrolytic capacitors: their fabrication and the interpretation of their operational behaviour (1973)

The various stages in the production of an aluminium electrolytic capacitor are outlined and these are then related to the equivalent circuit so as to establish an understanding of the preparation parameters that affect the performance. Particular reference is made to studies undertaken on the effects of etching prior to anodization, the anodization itself, the electrolyte used and the mechanical construction. In the case of sintered porous tantalum electrolytic capacitors, the parameters are not so well understood but comparisons will be drawn with aluminium capacitors wherever possible.

Introduction to Special Issue: Security, Socioecology, Polity: Mande Hunters, Civil Society, and Nation-States in Contemporary West Africa (2004)

The public prominence of hunters and their organizations is a striking phenomenon in West Africa. Whether on the streets or rural byways of the countries stretching from Sierra Leone to Cote d'Ivoire, or in media, internet, or policy debate, hunters seem to be everywhere: as security guards, civildefense fighters, environmental guardians, spokesepeople for rural development projects, actors in party politics, and articulators of emergent regional and ethnic identities. In the warfare that beset the region in late 2002, hundreds of hunters were fighting in COte d'Ivoire in a conflict with strong potential, according to some commentators, for spread into Guinea (http://www.irinnews/org/webspecials/ClCrisis/, 4 December 2002). As the Kamajor civil-defense force, hunters had played a decisive role several years earlier in Sierra Leone's civil war (Muana 1997). In the environmental arena, hunters are now forefronted as the key force to guard national parks and implement global conservation objectives. A suggestion that European donor agencies might inadvertently be building in Guinea an armed rebellion (Leach 2000) may prove to have been alarmingly prophetic. The papers in this collection expose and reflect on the new roles that hunters are playing in West Africa's political and social affairs, in a variety of national and local settings. Most of the papers were first presented at the 2002 African Studies Association Meetings in Washington, D.C., on the panel Mande Hunters, Nation-States, and Civil Society in Contemporary West Africa, co-organized by Joseph Hellweg and Thomas Bassett and sponsored by the Studies Association. I served as discussant. Mariane Ferme and Danny Hoffman subsequently completed the collection with their contribution. Joseph Hellweg coordinated and edited the papers into the present issue. In these articles, Thomas Bassett and Joseph Hellweg focus on different aspects of hunters' roles in political and military security in Cote
Soil and Compost Filters of Malodorant Gases (1975)

Removing low concentrations of pollutant gases from air streams is difficult and expensive.1,2 Removal techniques include water scrubbing (with and without permanganate, hypochlorite, or lime), burning, and sorption by activated charcoal. The shortcomings of these techniques are that they require fuel, maintenance, water, high capital costs, they pollute the wash water, and/or some concentrate only, rather than remove the offender.
The China outbound market: An evaluation of key constraints and opportunities (1998)

Chinese outbound tourism has grown rapidly, reaching 5 million in 1995 and with the potential for significant further growth. This potential was boosted in late 1996 when the Chinese Government relaxed its foreign exchange policy for outbound tourists and out bound travel businesses, thereby overcoming a major constraint to outbound tourism. A Chinese outbound tourist is defined here as a resident of mainland China and travels tem porarily outside mainland China for any pur pose. Drawing upon a survey of constumers and of key informants, this paper outlines the main characteristics of tourists from mainland China and identifies main impediments to continuing market growth. It is concludet that Chinese tourists are drawn initially to the most frequented attrac tions overseas, and particularly to those which offer a marked contrast with what is found in China. The intrinsic attributes of the attrac tions are found to be of secondary importance. It is suggested that destination countries serious about the Chinese market need to liberalise booking procedures as a matter of urgency. Greater promotion by destination countries is needed within China to improve travel industry and consumer awareness.
Decreased fibrinolytic response to adrenergic stimulation in hypertensive patients (1989)

The aim of this study was to assess the function of the fibrinolytic system at rest and in response to adrenergic stimulation in patients with stable essential hypertension as compared with normotensives. At rest, essential arterial hypertensives were characterized by increased levels of circulating tissue-plasminogen activator, associated with an increased activity of its specific inhibitor, the PAI-1. After stress, fibrinolytic response was impaired in essential arterial hypertensives despite a greater release of tissue plasminogen activator by endothelial cells. Therefore, the PAI-1 activity may be increased in essential arterial hypertensives not only at rest, but also after stress. This may represent a risk factor for hypertensive patients.
Practical Field Use of Eye-tracking Devices for Consumer Research in the Retail Environment (2013)

Eye-tracking equipment is now affordable and portable, making it a practical instrument for consumer research. Engineered to best analyze gaze on a plane (e.g., a retail shelf), both portable eye-tracking glasses and computer monitor–mounted hardware can play key roles in analyzing merchandise displays to better understand what consumers view. Researchers and practitioners can use that information to improve the sales efficacy of displays. Eye-tracking hardware was nearly exclusively used to investigate the reading process but can now be used for a broader range of study, namely in retail settings. This article presents an approach to using glasses eye tracker (GET) and light eye tracker (LET) eye-tracking hardware for applied consumer research in the field. We outline equipment use, study construction, data extraction as well as benefits and limitations of the technology collected from several pilot studies.
Extracellular vesicles as a platform for membrane‐associated therapeutic protein delivery (2018)

Membrane proteins are of great research interest, particularly because they are rich in targets for therapeutic application. The suitability of various membrane proteins as targets for therapeutic formulations, such as drugs or antibodies, has been studied in preclinical and clinical studies. For therapeutic application, however, a protein must be expressed and purified in as close to its native conformation as possible. This has proven difficult for membrane proteins, as their native conformation requires the association with an appropriate cellular membrane. One solution to this problem is to use extracellular vesicles as a display platform. Exosomes and microvesicles are membranous extracellular vesicles that are released from most cells. Their membranes may provide a favourable microenvironment for membrane proteins to take on their proper conformation, activity, and membrane distribution; moreover, membrane proteins can cluster into microdomains on the surface of extracellular vesicles following their biogenesis. In this review, we survey the state-of-the-art of extracellular vesicle (exosome and small-sized microvesicle)-based therapeutics, evaluate the current biological understanding of these formulations, and forecast the technical advances that will be needed to continue driving the development of membrane protein therapeutics.
Retinal Effects of a Multiple-Pulse Laser (1974)

The eyes of 38 anesthetized rhesus monkeys were exposed to near-infrared laser radiation from a repetitive-pulse gallium arsenide laser. Pulse repetition frequencies of 40 pps and 1000 pps were utilized with a 30-nsec pulse width at the wavelength of 905 nm. Lesions for threshold determination were placed in the temporal paramac* ular area and could be produced only by varying exposure duration with fixed energy output. Therefore, the resultant 50% probability of damage values (ED50) were expressed as total exposure duration rather than energy per pulse. The ED50 value of 0.72 second for the 1000-pps exposure is significantly lower than the 22.3 seconds for the 40-pps exposure and demonstrates a cumulative effect.
Lung metastasis detection and visualization on CT images: a knowledge‐based method (2002)

Abstract A solution to the problem of lung metastasis detection on computed tomography (CT) scans of the thorax is presented. A knowledge‐based top‐down approach for image interpretation is used. The method is inspired by the manner in which a radiologist and radiotherapist interpret CT images before radiotherapy is planned. A two‐dimensional followed by a three‐dimensional analysis is performed. The algorithm first detects the thorax contour, the lungs and the ribs, which further help the detection of metastases. Thus, two types of tumors are detected: nodules and metastases located at the lung extremities. A method to visualize the anatomical structures segmented is also presented. The system was tested on 20 patients (988 total images) from the Oncology Department of La Chaux‐de‐Fonds Hospital and the results show that the method is reliable as a computer‐aided diagnostic tool for clinical purpose in an oncology department.

De re bibliográfica: una magnífica historia universal que perteneció a la biblioteca de Jerónimo Zurita (1984)

In this study, land use change and its effects on level and volume of groundwater were investigated. Using satellite images and field measurements, change in land uses was determined from 1998 to 2007. By analyzing the observation wells data and preparing the zoning maps in GIS, groundwater level fluctuations were assessed. Considering the area corresponding to these fluctuations, changes in aquifers volume were calculated. The rain gauge and synoptic stations data were used to calculate meteorological parameters and evapotranspiration. The water requirement of the main crops was determined by CROPWAT software. Results showed an increase in average rainfall and crops water requirement. The classification of satellite images showed that 11,800 ha was increased in lands under irrigated crops cultivation, while 27,655 ha of rangeland was declined in the region. Groundwater levels dropped an average of 7 m, equal to 63.4 MCM reductions in volume of water in the aquifer.
Analýza vybraných morfologických charakteristik pro rybniční sítě ve čtyřech oblastech (2017)

Hustota rybníků a jejich vlastnosti jsou značně proměnlivé na různých místech republiky, což je ovlivněno mimo jiné přírodními podmínkami a historickým vývojem.
The point correlation dimension of R-R intervals predicts sudden cardiac death among high-risk patients (2002)

An algorithm for the correlation dimension, the PD2, accurately tracks dimension in nonstationary data. Low-dimensional PD2s predict ventricular fibrillation (VF) in experimental myocardial infarction in animals. The authors now demonstrate in 61 electrocardiographic recordings from ambulatory high-risk cardiac patients that low-dimensional chaos in the heartbeat intervals, as represented by a reduction in PD2 below 1.2 dimensions, precedes lethal VF by a mean of 12 hours. This PD2-reduction occurs only in those high-risk patients who actually experience PD2-reduction had a high sensitivity (100%) and specificity (83%) in predicting VF among the high-risk patients. In contrast, the standard deviations of the same heartbeat intervals provided no such discrimination. In symptomatic extremely-high-risk patients, each having a history of syncope and episodic ventricular tachycardia, but who did not experience VF that day, PD2s<1.2 were observed in 9 of 10 subjects. This latter result suggests that VF-prediction and VF-occurrence may be separated by days not just hours. It is concluded that the PD2 of heartbeat intervals may provide an important diagnostic test and early warning signal for sudden cardiac death.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Carbodiimide modification of superhelical PM2 DNA: considerations regarding reaction at unpaired bases and the unwinding of superhelical DNA with chemical probes (1977)

Superhelical PM2 DNA I can be modified with N-cyclohexyl-N'-beta-(4-methylmorpholinium)ethyl carbodiimide (CMC). The transition of the sedimentation coefficient uncorrected for buoyant density change (S20,*) vs. % reactivity in terms of base pairs shows the following characteristics. The S20,* increases by 4.5 S units upon 1% modification. There is a plateau in S20,* between 1 and 4% reactivity. The extent of reactivity was determined by buoyant density and 14C radioactive CMC binding measurements. Further reactivity was not explored since Pulleyblank and Morgan's (22) data of S20,* vs. % reactivity from 6 to 34% was previously published. The initial results obtained in this study are complementary to the cited results of the above authors. Consequently, both sets of data taken together represent a complete description of S20,* vs. % reactivity with CMC. It is shown that the model in which superhelical DNA is proposed to contain small intrastrand hairpin regions can be extended to account for the observed transitions in S20,* vs. reactivity.

The<i>Participedia</i>Project: An Introduction (2011)

ABSTRACT Participedia is an open-source, participatory knowledge tool that responds to a new global phenomenon: the rapid development of experiments in new forms of participatory politics and governance around the world. The experiments are diverse and widespread, from the British Columbia Citizens' Assembly in Canada and the Oregon Citizens' Initiative in the United States to Participatory Budgeting in Brazil, deliberative forums in China, Panchayati Raj reforms in India, and citizen technology assessment in Denmark. Our knowledge of this rapidly expanding universe is shallow. The authors of this article, together with several others, have created the Participedia to respond to this deficit in knowledge. This article documents the development of the Participedia project to date. Participedia aims to be useful to scholars (and practitioners) as an open-source, real-time, cumulative qualitative and quantitative data repository about participatory and deliberative governance experiences. We believe that Participedia is the first effort in the social sciences to build a large data set through a method that is both crowd-sourced and structured to produce good quality, comparable information. [Editor's Note: The authors of this article are two of the co-founders of Participedia.]
RODHA: Robust Outlier Detection using Hybrid Approach (2012)

The task of outlier detection is to find the small groups of data objects that are exceptional to the inherent behavior of the rest of the data. Detection of such outliers is fundamental to a variety of database and analytic tasks such as fraud detection and customer migration. There are several approaches[10] of outlier detection employed in many study areas amongst which distance based and density based outlier detection techniques have gathered most attention of researchers. In information theory, entropy is a core concept that measures uncertainty about a stochastic event, and it means that entropy describes the distribution of an event. Because of its ability to describe the distribution of data, entropy has been applied in clustering applications in data mining. In this paper, we have developed a robust supervised outlier detection algorithm using hybrid approach (RODHA) which incorporates both the concept of distance and density along with entropy measure while determining an outlier. We have provided an empirical study of different existing outlier detection algorithms and established the effectiveness of the proposed RODHA in comparison to other outlier detection algorithms.
A novel anti-inflammatory in treatment of acne vulgaris: the pseudopterosins. (2013)

The pseudopterosins derived from the marine gorgonian octocoral, P. elisabethae are novel biologically active compounds increasingly recognized for their anti-inflammatory, analgesic, and wound healing properties among other clinical attributes yet to be discovered. These and a multitude of other natural products derived from the sea are now being harnessed and advanced for their biological activity and promising therapeutic benefits. With continued research, the enormous potential for using these compounds in managing acute and chronic inflammatory cutaneous disorders is both exciting and inevitable.
Localized Ridge Augmentation in Dogs: A Pilot Study Using Membranes and Hydroxyapatite (1990)

This study was designed to evaluate the potential to reconstruct localized ridge defects with bone by preventing non-osteogenic extraskelatal connective tissue from participating in the process of healing following experimental ridge augmentation treatment procedures. Following the elevation of buccal muco-periosteal flaps, buccal, interproximal, and interradicular bone was removed to the apical level of the second and third premolar teeth and the teeth were extracted to create bucco-lingual ridge defects that averaged 13 mm x 7 mm x 3.5 mm in each quadrant of two adult beagle dogs. The defects were permitted to heal for 90 days. The defects did not fill in with new bone. Subsequently, buccal muco-periosteal flaps were elevated and a membrane was placed over the defect and positioned so that it rested on bone that was exposed adjacent to the defect. In two quadrants test support materials were used to ensure that a space was maintained between the surface of the defect and the membrane. One quadrant was maintained as a sham-operated control site, three sites received membranes and no supporting implants and two sites received supporting implants and no membranes. The surgical schedule was designed to yield sacrifice times of 8 to 12 weeks. In the three quadrants available for study that were covered with membranes, bone and/or non-mineralized connective tissue was found to fill all of the space that had been provided by the membrane. Histologic examination confirmed that the space was filled with young, actively growing bone by 90 days. No new bone formation (bone fill) was observed in the sham-operated control site.
Real-time H.263+ video transmission on 802.11 wireless LANs (2002)

Wireless video services in packet-switched environments constitute a significant challenge. While radio channels present limited capacity high error rates and time-varying and asymmetric propagation properties, video applications are bandwidth-killing, error-sensitive and delay-intolerant. This situation forces wireless video systems to dynamically adapt to changes in the network resources. In the recent past there have been some papers investigating video transmission over wireless networks (H. Liu and M. El Zarki, 1997; N. Chan and P.T. Mathiopoulos, 2000), performance of the transfer protocols proposed in the IEEE 802.11 standard (H.S. Chhaya and S. Gupta, 1996; J. Weinmiller et al., 1997), and real time video communications in packet-switched infrastructure networks (P. Bahl, 1998). However, no previous experimental work on video conferencing systems for IEEE 802.11 Ad Hoc WLANs supporting IP multicast extensions has been reported so far. The paper describes Kinesis, an H.263+video transmission system for 802.11 network. Kinesis supports IP multicast extension and implements real time transport protocols to manage synchronization and QoS issues. We focus on the system architecture as a general communication framework for distributed and interactive audiovisual applications. Kinesis has been tested under different working conditions, performing H.263+ video sequences with excellent results.
