Acoustical Aspects of Woodwind Instruments

This classic, now revised and updated, shows how scientific calculations can be used to improve the understanding, design, and tuning of woodwind instruments. A powerful tool for correcting tuning errors in existing instruments and for creating new designs, Nederveen's work has long been a standard in the field of acoustics. In an extended new chapter, Nederveen analyzes and interprets recent developments in research on the acoustics of woodwind instruments. This revised edition, which also contains a new list of symbols and a new subject index, is a necessity for scholars, teachers, and practitioners of music, physics, acoustics, and woodwind design.
Influence of storage conditions on the quality of two varieties of native potato (Solanum Tuberosum group phureja)•

Las variedades nativas presentan la oportunidad para recuperar la biodiversidad y contribuir a la seguridad alimentaria en algunas regiones de bajo desarrollo, sin embargo no han sido estudiadas lo suficiente. Se someten a diferentes temperaturas de almacenamiento las variedades de papa nativa Curiquinga y Ratona Morada cultivadas en el departamento de Nariño para observar el comportamiento de característicascomo humedad, pérdida de peso, contenido de glucosa y ácido ascórbico. La variedad Ratona Morada conserva mejor sus características en refrigeración, deteriorándose más rápido en incubación, la Curiquinga en cambio presenta mayor deterioro en refrigeración que en temperatura ambiente e incubación. Se recomienda profundizar los estudios de almacenamiento pos cosecha en variedades nativas para enlazar la producción con el procesamiento que permita generar cadenas agroindustriales de valor agregado, conservar estos recursos genéticos y brindar alternativas a pequeños productores.
Population Genomics of Nontuberculous Mycobacteria Recovered from United States Cystic Fibrosis Patients

Nontuberculous mycobacteria (NTM) pose a threat to individuals with cystic fibrosis (CF) due to an increased prevalence of pulmonary infections, innate drug resistance of the bacteria, and potential transmission between CF patients. To explore the genetic diversity of NTM isolated from CF patients within the United States (US) and to identify potential transmission events, we sequenced and analyzed the genomes of 341 NTM isolates from 191 CF patients as part of a nationwide surveillance study. The most abundant species in the isolate cohort were Mycobacterium abscessus (59.5%), followed by species in the Mycobacterium avium complex (37.5%). Phylogenomic analyses of the three M. abscessus subspecies revealed that more than half of CF patients had isolates in one of four dominant clones, including two dominant clones of M. abscessus subspecies abscessus and two dominant clones of M. abscessus subspecies massiliense. M. avium isolates from US CF patients, however, do not have dominant clones and are phylogenetically diverse. Longitudinal NTM isolates were compared to determine genome-wide single nucleotide polymorphisms (SNPs) that occur within patients over time. This information was used to compare between and within-patient SNP distributions, to quantitatively define SNP thresholds suggestive of transmission, and calculate a posterior probability of recent transmission given the SNP distance between two isolates from different patients. Out of 114 patients with M. abscessus subspecies, ten clusters of highly similar isolates from 26 patients were identified. Among the 26 patients in the M. abscessus clusters, 12 attended the same CF care centers. No highly similar isolate clusters were observed in M. avium. Our study reveals the contrasting genomic diversity and epidemiology of two major NTM taxa and the potential for between-patient exposure and cross-transmission of these emerging pathogens.
Information Systems Foundations: Theory Building in Information Systems

This volume presents the papers from the fifth biennial Information Systems Foundations Workshop, held at The Australian National University in Canberra from 30 September to 1 October 2010. The focus of the workshop was the foundations of information systems as an academic discipline. The emphasis in the 2010 workshop was on theory building in information systems, which is a non-trivial and difficult issue because the field deals with such a wide range of phenomena, from the highly technological in nature to the distinctly human and organisational in focus. The theory building problem stems from the fact that the sciences that underlie and deal with technologically-oriented fields generally result in theories that fit within the 'covering law' model—that is, are assumed and believed to have universal applicability and explanatory and predictive power—whereas, by contrast, theories in the human sciences are generally much more conditional, contextual, tentative and open to exceptions. Successfully marrying the two is a challenge that the chapters in this volume explore.
Biological screening of tri-jannarose as a recipe from Thai traditional medicine

Context: Tri-Jannarose (TJ) is a Thai traditional medicine recipe, the ingredients of which are betel palm seed (Areca catechu L.), Siamese neem tree root (Azadirachta indica A. Juss.), and heart-leaved moonseed vines (Tinospora cordifolia [Thunb.] Miers). The equal mixture of three plants indicated to treatment of antipyretic, diuretic, expectorate, nourishment and appetizing. Aims: Phytochemical screening, antioxidant, and α-glucosidase inhibitory activities of TJ using different extractions were evaluated. Materials and Methods: The three plants of recipe were extracted using different solvents such as aqueous extract (ATJ), 50% ethanolic extract (HETJ), and 95% ethanolic extract (ETJ). The phytochemical screening was determined by total phenolic compounds and total flavonoid contents. The anti-oxidation were tested using by 2,2-diphenyl-1-picrylhydrazy (DPPH) radical scavenging and 2,2 -azinobis-(3-ethylbenzothiazoline-6-sulphonate) (ABTS+) assay. The α-glucosidase inhibitory activity was determined for glucose transferase mechanism. Results: Phytochemical screening found that this recipe had both phenolic and flavonoid substances. The ETJ (IC50 = 0.0463 ± 0.002) was exerted on antioxidation higher than HETJ and ATJ (IC50 = 0.0511 ± 0.000 and 0.1485 ± 0.005 mg/mL). Surprisingly, ABTS+ assay, ETJ (IC50 = 0.015 ± 0.000 mg/mL), and HETJ (IC50 = 0.022 ± 0.000 mg/mL) showed high effect on free radical scavenging activity than the standard controls, ascorbic acid (IC50 = 0.025 ± 0.001 mg/mL), and Trolox (IC50 = 0.032 ± 0.001 mg/mL). The α-glucosidase inhibitory activity found that all of the extract including ATJ (IC50= 0.0127±0.02 mg/mL), ETJ (IC50= 0.0154±0.01 mg/mL) and ETJ (IC50= 0.0202±0.01 mg/mL) were more potent to inhibit α-glucosidase emzyme than acarbose (IC50=0.745±0.026 mg/mL) as a positive control. Conclusion: The pharmaceutical preliminary scarring was confirmed to treatment on Thai traditional medicine. The recipe composed with phenolic compounds and flavonoids contents which chemical substance were more potent anti-oxidation, and bittersweet flavor was stronger to α-glucosidase inhibitory activity.
Scalable Methods to Improve the Communications in Peer-to-Peer Networks

Scalability is a beneficial property for any kind of system. Generally, scalability ensures that the system can handle growing amounts of work in a graceful manner. In this dissertation, I examine the scalability of communication protocols in Peer-to-Peer (P2P) computer networks. The success of P2P file sharing applications is due to the outstanding features of this network architecture. As network participants, peers, join the system, they contribute with resources such as bandwidth, storage and processing capacity, or the content itself; moreover, the P2P architecture eliminates single points of failure. P2P can be present at various levels of network technologies, from access to backbone or provider networks, up to the P2P overlays of end-user host nodes in the Internet. In this dissertation, I examine two different P2P services: the routing in wireless ad hoc networks, and the information retrieval in structured application-level overlays built over Distributed Hash Tables. In our days, the state-of-the-art technology for ad hoc wireless communication is the 802.11 family. The contention-based medium access provides communication for wireless mobile nodes without the coordination of a base station. In order to access nodes in the ad hoc network indirectly, every node in such a network must provide a routing service. This dissertation discusses the scalability of ad hoc routing solutions, and proposes a routing architecture that enhances the scalability of routing in ad hoc networks. The other topic of this dissertation is related to structured P2P networks. In these networks peers are spanned by a logical topology in order to ensure fast and economic lookups. One of the first such networks is Content-Addressable Network (CAN) that has a notable drawback regarding lookup cost compared to other similar algorithms. This dissertation aims to present an enhancement of the CAN algorithm, which exploits the special features and benefits of the original solution, but constructs an overlay network that can eliminate the known shortcomings of CAN. The enhancement prepares CAN to overcome its competitors, such as Chord and Kademlia, in lookup cost and signaling traffic, and introduces a new adaptive feature for DHT routing.
An Analysis of Heart Disease Prediction using Different Data Mining Techniques

Heart disease is a term that assigns to a large number of medical conditions related to heart. These medical conditions describe the abnormal health conditions that directly influence the heart and all its parts. Heart disease is a major health problem in today’s time. This paper aims at analyzing the various data mining techniques introduced in recent years for heart disease prediction. The observations reveal that Neural networks with 15 attributes has outperformed over all other data mining techniques. Another conclusion from the analysis is that decision tree has also shown good accuracy with the help of genetic algorithm and feature subset selection.
Molar variation of water: alkoxy in the preparation of SiO2-DA materials and its effect on dopamine release from an implantable reservoir in the brain

In the present work the one-step sol–gel process using silicon ethoxide (TEOS) has been used to prepared amorphous SiO 2 -Dopamine materials varying the molar water:TEOS ration (r H2O ) of 10, 20 and 40 respectively. The main purpose is to determined the influence of the r H2O variation on the final physic-chemical properties of silica-dopamine materials and its subsequent effect on the dopamine release properties. Several technique were used to characterized the result materials and a typical in-vitro dopamine release experiment was performed. The result materials consist of aggregated of nanoparticles that generate mesopores ranging from 33 to 59 Å. There is not a direct correlation between the increase r H2O with the textural properties and dopamine release. We suppose that the dopamine release not only is affected by the textural properties but also by the formation of superficial  Si-OH groups and their interaction with dopamine
Shear-Wave and Strain Ultrasound Elastography of the Supraspinatus and Infraspinatus Tendons in Patients with Idiopathic Adhesive Capsulitis of the Shoulder: A Prospective Case-Control Study

Objective To compare the elasticity of the supraspinatus tendon (SST) and infraspinatus tendon (IST) in patients with idiopathic adhesive capsulitis of the shoulder (ACS) with those in the control groups and to evaluate the relationship between age and tendon elasticity. Materials and Methods The Institutional Review Board approved this prospective, case-control study, which was conducted between November 2017 and March 2018, and informed consent was obtained from all participants. Control groups comprised healthy individuals or those with asymptomatic contralateral shoulders. Twenty-five shoulders in 20 participants in the ACS group (14 women; 53.5 ± 7.9 years) and 24 shoulders in 18 participants in the control group (6 women; 52.6 ± 10.5 years) were included. Elastography was performed in the oblique coronal plane at the neutral shoulder position. Mean/maximum/minimum velocity and stiffness from the shear-wave ultrasound elastography (SWE) and strain ratio (subcutaneous fat/target-tendon) from the strain ultrasound elastography (SE) of the SST and IST were evaluated. Statistical analyses were performed using the Mann-Whitney U test, receiver operating characteristic (ROC) curve, and Spearman correlation. Results Both velocity and stiffness in SWE were higher, and the strain ratio in SE was lower in participants with symptomatic shoulders than in those with normal shoulders (p < 0.001). SST- and IST-mean velocity, mean stiffness, and strain ratios showed excellent area under the ROC curve (> 0.970). The elastic modulus was little correlated with age (ρ = −0.340–0.239). Conclusion SWE and SE indicated that SST and IST were stiffer in patients with ACS than in those with normal shoulders regardless of aging.
A microcosm study in the reductive dechlorination of tetrachloroethylene using fermentation acids and alcohols as electron donors

A MICROCOSM STUDY IN THE REDUCTIVE DECHLORINATION OF TETRACHLOROETHYLENE USING FERMENTATION ACIDS AND ALCOHOLS AS ELECTRON DONORS by Anthony Siccardi III Anaerobic microcosms of Arthur Kill (New Jersey) sediment were used to investigate the effects of several electron donors on tetrachloroethylene (PCE) dechlorination activity. The substates tested were methanol, butanol, butyrate, lactate and succinate both by themselves and in various combinations. Different levels of PCE dehalogenation were noticed in all of the microcosms regardless of the electron donor used. Vinyl chloride was the major dehalogenation product detected in the majority of the microcosms. The causitive organism or group that carried our the reductive dehalogenation was not identified. Only the microcosms admended with a mixture of butanol/methanol were able to fully reduce the PCE to ethene and ethane. No correlations could be drawn between the added electron donors and their metabolic products with the reductive dechlorination process.

Antisickling Effects of Quercetin may be Associated with Modulation of Deoxyhaemoglobin, 2, 3-bisphosphoglycerate mutase, Redox Homeostasis and Alteration of Functional Chemistry in Human Sickle Erythrocytes.

Abstract It is now glaring that sickle cell anaemia is still one of the highest leading inbred hemoglobinopathy amongst Africans. This study examined the antisickling effects of quercetin via modulation of deoxy-haemoglobin, redox homeostasis and alteration of functional chemistry in human sickle erythrocyte using in silico and in vitro models while espousing preventive and curative approaches. Quercetin was docked against deoxy-haemoglobin and 2, 3-bisphosphoglycerate mutase, with binding energies (−30.427 and −21.106 kcal/mol) and Ki of 0. 988μM and 0. 992μM at their catalytic sites via strong hydrophobic and hydrogen bond interactions. Induction of sickling was done using 2% metabisulphite at 3h. Treatment with quercetin prevented sickling outstandingly at 5. 0μg/mL and reversed same at 7. 5μg/mL, 83.6% and 75.9%, respectively. Quercetin also significantly (P<0.05) maintained the integrity of erythrocyte membrane apparently from the observed % haemolysis relative to untreated. Quercetin significantly (P<0.05) prevented and counteracted lipid peroxidation while stimulating GSH and CAT levels which were detected to considerably (P<0.05) increase with simultaneous significant (P<0.05) reduction in SOD level based on curative approach. Umpiring from our FTIR results, a favorable alteration in the part of functional chemistry in terms of shifts (bend and stretches) and functional groups were observed relative to the induced erythrocyte/untreated. Thus, antisickling effects of quercetin may be associated with modulation of deoxy-haemoglobin, redox homeostasis and alteration of functional chemistry in human sickle erythrocytes.
E-BEB Algorithm to Improve Quality of Service on Wireless Ad-Hoc Networks

The Medium Access Control (MAC) protocol is the main element which determines the system throughput in Wireless Local Area Networks (WLANs) IEEE 802.11 standard. The MAC technique of the IEEE 802.11 protocol is called Distributed Coordination Function (DCF). In DCF, stations contend for the use of the channel in distributed manner via the use of the Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) protocol. In the CSMA/CA protocol, each station sets up a Backoff time according to a randomly selected interval from zero to the Contention Window (CW) for an additional deferral time before transmitting. The random Binary Exponential Backoff (BEB) algorithm is used to randomize moments at which stations try to access the wireless medium. However, in the random Backoff mechanism, packet collisions are not entirely eliminated, and the system throughput decreases when the number of stations is large, and there is no fairness between stations. The BEB algorithm has a number of disadvantages; one crucial disadvantage is the problem of fairness. In this paper, we analyze the behavior of the BEB algorithm used in IEEE 802.11 standard. We propose an Enhanced Binary Exponential Backoff (E-BEB) algorithm to improve the fairness of the channel access for BEB algorithm. Our E-BEB algorithm adjusts the way of increase or decrease of the contention window CW based on the number of the frame which is sent successfully. We propose several configurations, and we use NS2 simulator to analyze the network's fairness of the channel access of the E-BEB algorithm. The simulation results show that compared with other algorithms like BEB or Improved BEB (I- BEB), the E-BEB algorithm improves the fairness of the channel access and increases the network's throughput capacity; which is an valuable Quality of Service (QoS) parameter.
Childhood Obesity Differences in Single-Father and Single-Mother Families

ABSTRACT Prior research consistently finds that children living in two-parent families are less likely to be obese than children in single-parent families. Most of the research that explores the relationship between family structure and childhood obesity is limited in its conceptualization of family structure, however, either ignoring single-father families or bunching them in the same category as single-mother families. Research on gender and families suggests that single fathers are different from single mothers in ways that may influence a child’s risk of obesity. We use data from the kindergarten wave of the Early Childhood Longitudinal Study, Kindergarten Class of 1998–1999 to explore differences in obesity rates for young children in single-father and single-mother families. Compared to single mothers, single fathers earn more and provide a slightly healthier home environment (less TV watching and more sharing of meals) but are more likely to work outside the home full-time. Children in single-father families are also more likely to be white and have fewer siblings. These differences counteract one another, resulting in similar levels of obesity in these two types of single-parent families.
A bibliometric analysis of linguistics in web of science

The present study investigated the bibliometric characteristics of linguistics as represented in Web of Science (WoS), focusing on the number of linguistics publications between 1900 and 2013 in the Social Science Citation Index (SSCI) and between 1975 and 2013 in the Arts and Humanities Citation Index (A&HCI). Results showed that between 1975 and 2013, SSCI covered a total of 54,263 (0.86% of all SSCI) publications in the language linguistics category, 99,502 (1.61% of all SSCI) publications in the linguistics category, and 109,469 (1.81% of all SSCI) publications in the linguistics research area. Additionally, A&HCI covered a total of 187,239 (4.37% of all A&HCI) in the language linguistics category, 64,356 (1.48% of all A&HCI) in the linguistics category, 193,619 (4.52% of all A&HCI) publications in the linguistics research area. As SSCI and A&HCI have expanded over the years, the number of linguistics publications has increased as well. On average, SSCI ranked the language linguistics category no. 62.51, linguistics category no. 35.3, and the linguistics research area no. 21.69; whereas, A&HCI ranked the language linguistics category no. 9.33, linguistics category no. 22.15, and the linguistics research area no. 7.92. Based on these results, we can conclude that linguistics is an important field in both the social sciences and arts and humanities as covered in WoS.
The Choir Books of San Giorgio Maggiore in Venice: Results of in Depth Non-Invasive Analyses

This paper discusses a cross-disciplinary, international collaboration aimed at researching a series of 15th century choir books at the abbey of San Giorgio Maggiore on the homonymous island in Venice. Produced for the abbey itself, the books have never left the island during their 500-year history, thereby allowing a unique opportunity to analyse historic artefacts, which have undergone little modification over time. Prompted by ongoing cataloguing work on the manuscripts, a week-long analytical campaign using a combination of non-invasive analytical methods used in portable configuration allowed the comprehensive characterisation of ten volumes. The manuscripts’ palette and painting techniques were analysed using near-infrared imaging, reflectance spectroscopy in the UV-vis-NIR range, Raman spectroscopy, X-ray fluorescence mapping and digital microscopy. The paper will discuss the challenges linked to the fragility and the large dimensions of the volumes as well as the most interesting results of the investigation. These include the detection of unusual painting materials such as bismuth ink, as well as the discovery of a less homogeneous palette than originally expected, which prompted a partial revision of the attribution of the decoration in one of the volumes to a single artist.
