Deglaciation of the North Cascade Range, Washington and British Columbia, from the Last Glacial Maximum to the Holocene
Authors: Riedel J.L.
Published: May 2017

Glacial retreat from the North Cascade Range after the Last Glacial Maximum (LGM) at approximately 21 ka until the end of the Pleistocene at 11.6 ka was complex and included both continental and alpine glaciers. Alpine valley glaciers reached their maximum extent before 21.4 ka, then underwent a punctuated retreat to valley heads. In the south, beyond the reach of ice sheet glaciation, several end moraines were deposited after the LGM. Moraines marking a re-advance of alpine glaciers to <5 km below modern glaciers were deposited from 13.7 to 11.6 ka.The Cordilleran Ice Sheet flowed south from near 52° north latitude in British Columbia into the North Cascades. At its maximum size the ice sheet covered more than 500 km2 and had a surface elevation of 2200 m in upper Skagit valley. Deglaciation commenced about 16 ka by frontal retreat of ice flanking the mountains. Surface lowering eventually exposed regional hydrologic divides and stranded ice masses more than 1000 m thick in valleys. Isolated fragments of the ice sheet disintegrated rapidly from 14.5 to 13.5 ka, with the pattern of deglaciation in each valley controlled by valley orientation, topography, and climate. Like alpine glaciers to the south, retreat of the ice sheet remnants was slowed by millennial scale climate fluctuations that produced at least one large recessional moraine, and multiple lateral moraines and kame terraces from elevations of 200-1400 m in most valleys. Large volumes of glacial meltwater flowed through the North Cascades and was concentrated in the Skagit and Methow rivers. Outburst floods from deep proglacial lakes spilled across divides and down steep canyons, depositing coarse gravel terraces and alluvial fans at valley junctions.Climate at the LGM was characterized by a mean summer temperature 6 to 7 ºC cooler than today, and 40% lower mean annual precipitation. Persistence of this climate for thousands of years before the LGM caused a 750-1000 m decrease in alpine glacier equilibrium line altitudes (ELA). In the southern North Cascades at 16 ka, glacial ELAs were 500-700 m lower than today, and during advances from 13.7 to 11.6 ka alpine glacier ELAs were 200-400 m lower.
La práctica formativa como escenario de aprendizaje significativo del cuidado de enfermería

Published: May 2017

Los docentes en enfermería tienen la responsabilidad de formar profesionales en enfermería humanos, idóneos y competentes para cubrir las necesidades de cuidado de la población y afrontar los retos existentes en materia de salud. Las prácticas formativas representan un espacio enriquecedor para el aprendizaje del cuidado de manera significativa en el logro de este propósito. Este artículo presenta una reflexión en torno al aprendizaje del cuidado durante las prácticas formativas en un programa de enfermería de Bogotá. Se abordan tópicos como la importancia de la formación en el cuidado, la influencia del contexto institucional y del modelo pedagógico, así como los significados de la práctica para estudiantes y docentes. Se concluye que la apertura, el diálogo abierto, la motivación, el conocer el ser humano que hay en el estudiante, el promover su autonomía y su reflexión, y el acompañarlo en su experiencia como cuidador son aspectos esenciales para el aprendizaje significativo del cuidado de enfermería durante las prácticas formativas y que estos espacios se constituyen en experiencias transformadoras no solo para el estudiante sino también para el docente.

The impact of keyword and full video captioning on listening comprehension
Authors: Bensalem Elias Adam
Published: May 2017

This study investigates the effect of two types of captioning (full and keyword captioning) on listening comprehension.Â  Thirty-six university-level EFL students participated in the study. They were randomly assigned to watch three video clips under three conditions.Â  The first group watched the video clips with full captions.Â  The second group watched the same video clips with keyword captions. The control group watched the video clips without captions. After watching each clip, participants took a listening comprehension test. At the end of the experiment, participants completed a questionnaire to measure their perceptions about the use of captions and the video clips they watched. Results indicated that the full captioning group significantly outperformed both the keyword captioning and the no captioning group on the listening comprehension tests.Â  However, this study did not find any significant difference between the keyword captioning group and the no captioning group. Results of the survey suggest that keyword captioning were a source of distraction for participants.Keywords: captions, video, listening comprehension, ESL.Â Â

Published: May 2017

Alzheimer's disease (AD) which is the most common cause of dementia, has two subtypes: early-onset and late-onset AD. Early-onset AD affects people younger than age 65 and memory dysfunction, cognitive impairment, executive dysfunction and language problems are relatively more common on patients with early-onset AD. Based on the language disturbances, the aim of this study is to examine basic sentences of patients with early-onset AD by using four different language tests and to compare all the results with a control group. Considering the power analyses, 23 patients with early-onset AD from Dokuz Eylul University, Faculty of Medicine, Department of Neurology and an age/education-matched control group are included in this study. The data were analyzed using t test and Mann-Whitney U test. It was found that patients with early-onset AD used more basic sentences in Random Speech test compared to the control group. The other finding was about the nominal and the verbal sentences. It was revealed that there was a statistically significant difference between the patients with earlyonset AD and the control group in terms of nominal sentences in the Picnic Picture description test, Cookie Theft Picture description test and the Story Picture Sequencing test. In terms of verbal sentences, it was found that there was a statistically significant difference between the patients with early-onset Alzheimer’s disease and the control group in all language tests. In conclusion, the syntactic ability is preserved in AD. However, working memory problems can make the syntactic processing worse. Due to this process, patients with early-onset AD tend to use basic sentence structures more frequently.

Published: May 2017

This study examined the internal headings of theses and research articles in applied linguistics. Headings collected from 110 theses and headings selected from 500 research articles underwent quantitative and qualitative analyses. The goal was to investigate possible differences between the heading writing styles adopted by the writers of each genre in focus. Analyses revealed the higher incidence of functional headings in both genres, particularly in research articles. Virtually, all functional and conventional syntactic options used in headings testified to be significantly different. Moreover, deployment of functional headings evidenced to act as a gatekeeper alternative that might have enhanced the publication chance of research articles in prestigious ISI-indexed journals. The study provides assistance for the writers of style guide manuals and syllabus designers in paving the way for novice writers to gain recognition in academia as professionals.Â Keywords: applied linguistics, conventional heading, functional heading, research article, thesis

Examining Certified Nursing Assistants ‘Perceptions of Work-Related Identity
Authors: Gray Jennifer A. , Lukyanova Valentina
Published: May 2017

Background

The purpose of this study was to examine certified nursing assistants ‘(CNAs') perceptions of their work identity within the context of their relationships with nursing facility residents and residents ‘family members. Such information can help clarify CNAs ‘roles and respond to their job needs. Although CNAs provide valuable care for residents, they often experience low status at work; it is important that they have opportunities to find value in their work.

Methods

Eight focus groups were conducted with 45 CNAs from 4 nursing facilities. Thematic analysis and role theory were used to analyze the data. Results: Participants identified with the roles of connector, advocate, overloaded worker, and companion.

Conclusions

CNAs expressed a lack of work-related control in the advocate and overloaded worker roles, and satisfaction in the companion role. Adequate organizational resources can help CNAs gain more satisfaction and effectiveness in their work.
Fading Away in Plain Sight
Authors: Lucier Shirley A.
Published: May 2017

The failure of health care professionals and providers to recognize and discuss end-of-life care continues to resonate across our heath care continuum. The value of the patient–clinician interaction is paramount in advocating for and establishing effective communication and care.

A meaningful nurse–patient relationship is a key component to facilitate discussion of patient and family choices in how care can be managed throughout the dying process. This article describes how, using Virginia Henderson's nursing model of patient-centered care, a holistic and palliative approach to end-of-life care was successfully supported in the home.
Reflective Practice as a Tool for Questioning Authority
Authors: LaRocco Susan A.
Published: May 2017

Reflective practice describes the cyclical interaction of learning and experience. Although the concept has been enhanced during the 20th century, the Chinese philosopher and educator Confucius indicated that wisdom is gained by reflection. Nurses can enhance their practice and gain professional satisfaction by developing the skills needed for reflective practice. Reflection can occur in the moment as well as after an event. To develop the skills needed for reflective practice, the nurse must first make a commitment to reflection. Reflection can lead to increased confidence, which allows nurses to use their voice to question authority.
Triggers and Their Influence on Health Behaviors
Authors: Gipson Christine S.
Published: May 2017

This article provides a conceptual definition of the concept trigger within the context of health behaviors and applies it to the highly significant health issue of obesity. Healthy behaviors are essential to life and happiness, but they do not just happen. They are triggered, and an inner drive keeps them alive. To help patients gain and retain optimal health, nurses must understand the triggers of healthy behaviors. Walker and Avant's (2011) method of concept analysis is used as the basis for defining the concept of trigger. The antecedents, defining attributes, and consequences of trigger are identified. Findings suggest that nurses can play a role in triggering health behavior change through simple motivational efforts.
The Importance of Healthy Academic Learning Environments in Nursing Education
Authors: Clay-Robison Shelly , Ruth-Sahd Lisa A.
Published: May 2017

Work environment is frequently discussed in nursing literature, particularly within the realm of practice and patient safety. However, there is limited literature regarding the work environment in academic settings and how it affects faculty and students. There is no literature that looks at work environments in relation to human needs theory. The purpose of this article is to highlight the significance of the work environment in academic settings in terms of human needs theory and to offer suggestions for creating and maintaining a healthy academic work environment.
Competition versus Collaboration in Health Care Teams
Authors: Chapa Orlando R. , Fuller Sobha M. , Hernandez Lisa J. , McCray TaShauna
Published: May 2017

Innumerable teams have emerged in health care, spurred by the desire to improve patient quality and satisfaction, provide better population outcomes, and reduce per capita cost. Team leaders are faced with many choices in team development, such as collaboration or competition. Although each approach has unique advantages and disadvantages, is one approach better suited to building the teams needed in today's environment? This review examines these two distinct team-building approaches. A literature review of these two approaches in light of the theoretical frameworks of social identity theory and team role theory shows support for both ends of the spectrum; however, collaboration was linked more often with highly successful and effective teams. Ultimately, the literature demonstrates that collaboration is better suited to developing teamwork capable of achieving today's complex health care goals.

Published: May 2017

Les caractéristiques anatomiques et les structures ovariennes et pathologiques du tractus génital de 500 femelles zébus (Bos indicus), appartenant à quatre races bovines (Azawak, Bororo, Djelli, Goudali), ont été étudiées à l’abattoir de Niamey au Niger du 15 août au 15 décembre 2011. Chaque animal a été examiné avant abattage. Ces vaches et génisses, âgées en moyenne de 8 ± 2,5 ans, ont eu une note d’état corporel moyenne de 1,6 ± 0,6 et un poids moyen de carcasse de 113 ± 21 kg. Les caractéristiques anatomiques du tractus génital n’ont pas présenté de différences entre les races (p > 0,05). Les caractéristiques suivantes ont été observées : diamètre du col 3,4 ± 1,1 cm, longueur du col 8,1 ± 2,5 cm, longueur des cornes 21,6 ± 5,2 cm, diamètre des cornes 1,6 ± 0,5 cm, longueur et largeur de l’ovaire droit respectivement 19,8 ± 4,4 et 11,2 ± 3,8 mm, de l’ovaire gauche 18,8 ± 4,5 et 10,2 ± 3,3 mm, et poids des ovaires droit et gauche respectivement 2,9 ± 1,8 et 2,5 ± 1,6 g. Un corps jaune a été identifié dans seulement 14 p. 100 des cas et l’absence de follicules visibles à la surface de l’ovaire a été notée dans 32 p. 100 des cas. Ces caractéristiques ont été ignificativement (p < 0,05) influencées par l’âge de l’animal. Parmi les femelles examinées, 7,4 p. 100 ont été confirmées gravides. Diverses pathologies de l’appareil génital (kystes, infections utérines, free-martinisme, pyomètre.) ont été observées sur 10,4 p. 100 des tractus génitaux.
Pathology and pathogenesis of bovine skin and meibomian gland demodicosis
Authors: Abu-Samra M. T. , Shuaib Y. A.
Published: May 2017

A national survey on bovine demodicosis was conducted among 48,000 cattle in Sudan during vaccination campaigns (44,800), and at antemortem and postmortem examination in abattoirs (3200). Among the total surveyed, 44,908 were adult (2-8 years) of which 34.6% were infected, and 3092 were calves (<  2 years) of which 34.6% were infected. Three hundred cattle with severe skin lesions among which 218 also had meibomian gland lesions were selected. The clinical pictures of skin and meibomian gland demodicosis were described. Proteus vulgaris, Pseudomonas aeruginosa, Staphylococcus aureus, Sta. epidermidis, Streptococcus pyogenes (group A) and Trueperella pyogenes were isolated from skin lesions, and Moraxella bovis and Sta. aureus were isolated from meibomian gland lesions. These bacteria produced deleterious toxins and enzymes aggravating the lesions caused by Demodex bovis and D. ghanensis mites in skin and meibomian glands, respectively. Neither mite was found in the internal tissues or organs, indicating that they had no endoparasitic phase. The histopathological changes observed were commensurate with cell-mediated immunity. Liberation of the contents of demodectic mange colonies in the subepidermal and dermal layers of the skin, and surrounding connective tissue of the meibomian glands evoked severe histopathological changes characterized by massive high-turnover granulomatous reactions with influx of macrophages and lymphocytes. The pathogenesis of the disease, from the stage of initial invasion of the hair follicles and collecting tubules of the meibomian glands by the mites and associated bacteria, to the stage of regression of the lesions was described. It was concluded that the nature of association between Demodex mites and bacteria in demodectic mange lesions was synergistic and of equal significance. The high-turnover granulomatous reactions which characterized the histopathological changes showed that Demodex mites and associated bacteria were persistent and immunogenic.
Principales intoxications végétales chez les ruminants en zone méditerranéenne
Authors: Mohammedi D. , Mohammedi S. , Keck G.
Published: May 2017

Les intoxications végétales chez les ruminants sont assez fréquentes mais elles restent méconnues et d’importance difficile à quantifier du fait de la diversité des plantes toxiques qui en sont responsables. Les impacts des intoxications végétales dans le Bassin méditerranéen devraient être mieux évalués pour les distinguer de ceux causés par des infections. En effet, les vétérinaires établissent difficilement un diagnostic d’intoxication végétale et incriminent souvent les agents infectieux. Il est donc important de réunir un maximum d’informations objectives, ce qui est souvent assez délicat au regard des informations relativement approximatives dans les descriptions des cas. Certaines plantes responsables d’intoxication ont une répartition très large au sud et au nord de la Méditerranée, y compris en France. D’autres sont au contraire relativement spécifiques des milieux désertiques du Maghreb et sont retrouvées notamment en Algérie. Les animaux les plus fréquemment concernés sont les ovins (61,5  p.  100), les bovins (24,7  p.  100), les dromadaires (9  p.  100) et les caprins (4,6 p. 100). Les intoxications rencontrées chez les ruminants sont provoquées par Hyoscyamus muticus spp. falezlez (Coss.) Maire, Ferula communis L., Thapsia garganica, Hypericum crispum L., Tetraena cornuta (Coss.) Beier & Thulin, Drimia maritima (L.)

Les paramètres physico-chimiques au cours de la maturation de quatre muscles (semitendinosus [ST], rectus femoris [RF], longissimus thoracis [LT] et semimembranosus [SM]), conservés à 4 °C, ont été mesurés chez des dromadaires mâles (10 jeunes de trois à quatre ans et 10 adultes de plus de cinq ans) de race Sahraoui. Une diminution de la température post mortem a atteint une valeur minimale de 5,7 ±  0,20  °C (LT) chez les adultes, alors que la valeur minimale enregistrée chez les jeunes a été plus basse avec 3,9 ± 0,68 °C (ST). Le pH des muscles étudiés a diminué au cours de la période post mortem. Les valeurs minimales enregistrées ont varié de 5,2 ± 1,11 (RF) à 5,7 ± 0,02 (LT) chez les chamelons, et de 5,6 ± 0,05 (SM) à 6,3 ± 0,53 (ST) chez les adultes. La quantité d’eau extractible a augmenté pour les quatre muscles et pour les deux groupes d’âge. Les valeurs maximales obtenues ont été de 0,21 ± 0,040 g par gramme de muscle RF jeune et de 0,21 ± 0,009 g par gramme de muscle RF adulte. Cela signifie que la capacité de rétention d’eau des différents muscles a diminué au cours du temps post mortem. La conductivité électrique n’a pas suivi le même profil pour tous les muscles étudiés. Une légère augmentation de ce paramètre dans le temps a été perceptible pour le muscle LT (117,3 ± 0,30 µS/cm/g) chez les jeunes, et ST (158,3 ± 0,14 µS/cm/g) chez les adultes.

Les hémoparasitoses (theilériose, babésiose et anaplasmose) sont des maladies vectorielles graves dont l’impact économique et sur la santé des élevages bovins au Maroc est considérable. L’objectif de cette étude, réalisée dans quatre régions d’élevage bovin laitier, a été de déterminer la séroprévalence et les facteurs de risque de ces infections. Au total 1 040 bovins ont été examinés dans 96 exploitations. La technique competitive enzyme-linked immunosorbent assay (cELISA) et la réaction d’immunofluorescence indirecte ont été utilisées pour la détermination de la séroprévalence, et le test statistique V de Cramer a permis d’analyser les facteurs de risque d’infection des bovins par les hémoparasites. Sur 1 040 sérums analysés, 689 (66,3 p. 100) ont été séropositifs ; la séroprévalence a varié selon le parasite considéré : Theileria annulata (35,4 p. 100), Anaplasma marginale (20,5 p. 100), Babesia bigemina (13,6 p. 100) et B. bovis (12,0 p. 100). Par ailleurs, 155 sérums (14,9 p. 100) ont présenté des infections mixtes (deux ou trois hémoparasites simultané- ment). L’analyse statistique a montré que l’âge (C = 0,62) et le type d’élevage (C = 0,60) ont eu une forte influence sur la séroprévalence, tandis que la race (C = 0,46) et le sexe (C = 0,29) ont eu une influence moindre. Le climat (C = 0,06) n’a pas semblé avoir d’impact. Ces résultats aideront à comprendre la situation épizootique des hémoparasitoses vectorielles chez les bovins afin d’établir une stratégie adéquate pour leur contrôle.

Le groupe social appelé les éleveurs familiaux a suscité l’intérêt des sciences sociales, économiques et environnementales. La principale caractéristique de ce groupe, présent dans le biome Pampa au sud du Brésil et en Uruguay, est la production basée sur le travail familial sur de petites parcelles, exprimant un mode de vie autonome, très dépendant toutefois de fortes relations avec le milieu naturel et marqué par l’aversion au risque. L’objectif de cet article a été de faire une analyse comparative des facteurs de vulnérabilité des éleveurs familiaux du sud du Brésil et d’Uruguay, ainsi que des perceptions de ces acteurs sociaux sur les risques et les stratégies mises en place pour atténuer les menaces. Une enquête a été menée dans le but de répondre à ces questions, à partir d’interviews de seize éleveurs familiaux, huit dans chaque pays, dans les villes de Santana do Livramento (Brésil) et Rivera (Uruguay). Le choix de ces communes a été lié au fait que, malgré leur proximité géographique de chaque côté de la frontière et leurs similitudes environnementales, l’élevage familial n’était pas soumis aux mêmes conditions politiques et économiques, ce qui pouvait ou non influencer leurs perceptions et leurs réactions. Les résultats ont montré que les éleveurs étaient principalement affectés par les vulnérabilités provenant de facteurs externes comme le climat (sécheresses ou hivers rudes, par exemple) mais aussi de facteurs internes (accès à la terre limité, successeurs). Du point de vue des éleveurs familiaux, les plus grands risques pour leur système de production et leur mode de reproduction sociale étaient plutôt liés aux variations climatiques qu’aux facteurs de prix et de marchés.

L’étude est centrée sur l’évaluation de la contribution de l’éle­vage de petits ruminants dans la réduction de la pauvreté et de la vulnérabilité des systèmes agricoles de trois zones agro­écologiques en Egypte : la zone pastorale du littoral Nord- Ouest (région de Matrouh), les zones irriguées de la vallée du Nil (région de Sohag) et les oasis du désert Ouest (région de la Nouvelle Vallée). Une étude empirique sur 90 exploitations dans les trois zones agroécologiques portant sur différents indicateurs économiques et sociaux liés à la pauvreté a donné des indications sur le rôle des ovins et des caprins dans dif­férents types d’exploitation, selon les dotations en ressources (en particulier terre, bétail, capital) et les ressources humaines. Les résultats ont montré que les petits ruminants constituaient la principale source de revenus des ménages pour échapper à la pauvreté, notamment pour les sans terre et les très petits propriétaires terriens. En outre, l’élevage était un capital qui générait d’autres richesses qui n’ont pas été prises en compte dans l’approche de la pauvreté monétaire.

Bilateral Deep Vein Thrombosis Associated with Inferior Vena Cava Agenesis in a Young Patient Manifesting as Low Back Pain
Authors: Langer Felipe , Dos Santos Daiane , Suertegaray Gustavo , Pereira Haygert Carlos Jesus
Published: May 2017

Congenital absence of the inferior vena cava is a rare vascular anomaly, and most cases are asymptomatic. Nevertheless, patients with inferior vena cava malformations may have increased risk of deep venous thrombosis. Particularly, cases of bilateral deep venous thrombosis may arise owing to an insufficient collateral venous drainage from the lower limbs. We hereby describe a case of a previously healthy young male patient presenting with bilateral lower limb deep venous thrombosis as the initial clinical manifestation of congenital inferior vena cava agenesis. We conclude that in young patients presenting with deep venous thrombosis, especially when thrombosis occurs spontaneously, bilaterally, or recurrently, inferior vena cava anomalies should be thoroughly investigated and ruled out as appropriate.

Nas últimas décadas as organizações percorreram o caminho da modernidade para a hipermodernidade: a empresa prevê os conflitos e se antecipa às reivindicações, atua com trabalhadores capacitados, que por sua vez aceitam e desejam mudanças, querem cooperar e são voluntários na busca da solução de problemas. O objetivo deste trabalho é analisar os processos de comunicação, decisão e liderança da Promon, uma empresa que adota o modelo participativo, com o propósito de identificar quais são os padrões culturais e as relações de poder que alavancam e/ou restringem a sua gestão. O referencial teórico adotado para contextualizar esse estudo teve como foco os seguintes assuntos: cultura e poder e processos de gestão no modelo participativo. Para o estudo de caso, realizou-se uma pesquisa qualitativa baseada em dados secundários. Após a análise dos resultados da pesquisa, foi possível constatar que, tal como consta na teoria apresentada sobre cultura e gestão participativa, na Promon a comunicação dissemina e reforça a sua cultura, há a busca do consenso nas decisões organizacionais e os líderes são considerados genuínos representantes dos empregados acionistas. Cabe destacar que, devido ao arranjo societário no qual 100% da empresa pertencem aos próprios empregados, a diretoria geral é eleita pelo voto direto e secreto dos acionistas. Esse estudo apresentou como limitações o fato de não incluir dados primários em sua investigação.

Ficus carica leaves are traditionally used in the treatment of various diseases namely vitiligo, diabetes, coughs, asthma, constipation and gingivitis. The aim of the present study was a preliminary phytochemical and thin layer chromatography (TLC) analysis of the various extracts of Ficus carica leaves. Phytochemical analysis was carried out using the standard phytochemical assays. TLC analysis of the chloroform and ethanol extract of the leaves was carried out using the solvent system Ethanol: Chloroform (9:1) and Ethanol: Hexane (3:7), respectively. The findings of the preliminary phytochemical screening revealed the presence of various chemical compounds like alkaloids, glycosides, flavonoids, carbohydrates, tannins, phenols, fixed oil and fats. The three Rf value (0.59, 0.78 & 0.94) and six Rf value (0.05, 0.21, 0.34, 0.51, 0.65 & 0.87) were found in TLC plate of chloroform and ethanol extracts, respectively. These studies provided referential information in regard to its identification parameters assumed significantly in the way of acceptability of herbal drugs in present scenario of lack of regulatory laws to control quality of herbal drugs.

Bauhinia purpurea are used as antinociceptive, antidiarrhoeal, anti-inflammatory, anti-arthritis, analgesic, anticancer, antipyretic, anti-diabetics, anti-diarrheal activity etc. The flavonoids and polyphenol are present in Bauhinia purpurea and may play an important role in the treatment of inflammation and arthritis. Till date no one has documented about active constituents responsible for the anti-inflammatory and anti-arthritis activity. The present study was aimed to isolate fractions from Bauhinia purpurea leaves extracts, and assessed their anti-inflammatory and anti-arthritis activity in rats. The hydroalcoholic and aqueous extracts of Bauhinia purpurea leaves were prepared and tested for in vitro antioxidant activity namely DPPH, total polyphenol content, total flavonol content and reducing power assay. The antioxidant activity was performed only for proper selection of extracts, to isolate the polyphenol and flavonoids fractions from extract expressing maximum antioxidant activity. The different fractions were isolated from hydroalcoholic extracts by using column chromatography. The fractions FBP5, FBP8, FBP9 and FBP10 were further investigated for phytochemical screening to determine the nature of isolated compound. The fractions FBP8, FBP9 and FBP10 were screened for anti-inflammatory and anti-arthritis activity in carrageenan rat induced paw oedema, cotton pellet-induced granuloma model and adjuvant induced chronic arthritis in rats. The findings of in vitro antioxidant activity demonstrated that hydroalcoholic extracts expressed higher antioxidant activity compared to aqueous extract, and hence hydroalcoholic extracts was further selected for the isolation of various fractions. The results of phytochemical study imply that FBP8, FBP9 and FBP10 revealed the presence of polyphenol and flavonoids.  The fraction FBP8, FBP9 and FBP10 (25 mg/kg) exhibits significant anti-inflammatory and anti-arthritis activity. The FBP9 produces maximum anti-inflammatory and anti-arthritis activity compared to other fractions. These findings suggest that the anti-inflammatory and anti-arthritis activity of isolated fraction was due to presence of flavonoids and polyphenols.

Livistona chinensis, Saribus rotundifolius and Areca catechu are palms primarily cultivated for ornamental purposes and also utilized in herbal remedies. The chemical and biological studies were conducted using standard procedures. Phytochemical screening revealed the presence of alkaloids, saponins, cardiac glycosides, terpenes, de-oxy sugars, anthraquinones, phenols, flavonoids and phlobatannins in varying amounts. The total phenolics content ranged from 52.0-245.0 mg/g, DPPH radical inhibition (87.30-90.55%, 2.0 mg/ml), iron chelating activity (27.3-65.0%, 0.5 mg/ml), hydrogen peroxide scavenging (93.18-98.46%, 0.5 mg/ml), and molybdate ion reduction capacity (15.93-58.30%, 0.5 mg/ml). L. chinensis extract showed notable antimicrobial activity against B. subtilis, P. aeruginosa and C. albicans (MIC = 75-100 µg/ml) while A. catechu and S. rotundifolius extracts were potent against all test pathogens (75-100 µg/ml), except S. typhi (150 µg/ml). However, no appreciable cytotoxic effects on human cervical (HeLa), lung (H460), breast (MCF-7) and prostate (PC-3) cancer cells at 30 µg/mL was observed for the extracts. The notable antioxidant and antimicrobial activities of the palm extracts are a function of their inherent bioactive constituents and a potential source of medicinally useful compounds. The chemical and biological assessment of S. rotundifolius palm nuts is reported for the first time.

Authors: Yap Matthew H. T. , Chen Nan
Published: May 2017

Sažetak Purpose – This paper aims to examine young Chinese wine consumers’ perceptions of the diffused wine information in China, and explore the factors that may influence their perceptions. Design – A positivism paradigm was employed to design the research. Methodology – Quantitative data were collected from a total of 507 young Chinese wine consumers via a self-administered structured questionnaire. Both descriptive and advanced statistics were employed to analyse the collected data. Approach – Respondents were selected using purposive sampling technique. Deductive approach was used to reason data. Research ethics were observed. Findings – Six dimensions (complexity, compatibility, relative advantage, observability, religion and ethics, and trialability diffused wine information) emerged via Principal Component Analysis. Young Chinese wine consumers’ perceptions of the diffused wine information were independent of their personal and professional backgrounds. However, consumers with different education levels and religions considered differently the expensiveness of wine to purchase. Their considerations of the expensiveness of wine to purchase were dependent on their awareness of alcoholic friends and family members, age, education levels and gender. Originality of the research – This study is possibly the first of its kind to employ the diffusion of innovation theory to examine young Chinese wine consumers’ perceptions.

The air space above the sovereignty of a state is closed to activities of other states except to getpermission from the subjacent state. Challenges and problems in the development and utilization ofnational air space region tend to increase and require problem solving prevention. One of them is theAmerican Google’s plan to cooperate with Indonesian government to put Google Balloon over the In-donesian national air space. The legal implications of this Google Balloon placement become the fo-cus of this study through system legal theory and legal effectiveness theory. Based on the resultsshow that First, from the legal substance aspect, status of Google Balloon cannot be categorized asan air or space vehicle; Second, viewed from the legal institutional aspects, the implementation ofthe project related to the competence of the relevant agencies which does not only involve the min-istry of communication and information but also involve the parliament; and Third, from the legalculture aspect, socialization towards the plan of the project needs to be expanded to prevent anyunfavorable circumstances.Keywords: Balloon Google, legal implications, the National Air Space
