Abstract: Blood pressure is currently a very important tool for clinical and veterinary surgery, especially in monitoring patients under anesthesia and in emergency situations. Hypertension can cause a number of changes in the body of dogs and cats, especially those who are middle-aged and elderly. In veterinary medicine, the blood pressure can be measured non-invasively and invasively. The non-invasive, or indirect technique, is frequently used during routine examinations since it presents convenience as it can be carried out quickly, although it is less accurate. For this research 245 dogs were selected, with one to ten years of age, of both sexes, castrated and uncastrated of different breeds and body scores. The dogs were weighed and had the body condition score determined using the system of 9 points, being categorized into: Control group, overweight group or obese group. Systolic blood pressure was obtained by non-invasive method using the Doppler flowmeter and the oscillometric method. 48 animals were excluded due to the high variability of values, with systolic blood pressure greater than 160 mm?Hg, as well as uncooperative and/or aggressive patients. There was agreement between both methods in 197 dogs conscious and asymptomatic and, therefore, this study showed that oscillometric method can be used in normotensive patients as the study was conducted in patients of different sizes, breeds, ages, body scores and sexual status.

Abstract: The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and S o Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus) and scaly-headed parrots (Pionus maximiliani). Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira). Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus). It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments. O objetivo deste trabalho foi pesquisar a frequência de ocorrência e a variedade de parasitas intestinais de animais silvestres de vida livre. Amostras de fezes de mamíferos e aves silvestres de centros de reabilita o dos Estados do Mato Grosso do Sul e S o Paulo, foram analisadas pelos métodos de sedimenta o e de centrífugo-flutua o. Foram encontrados ovos, oocistos, cistos e/ou trofozoítos de parasitas em 71% das amostras. Oocistos de Cryptosporidium sp. foram detectados em amostras de fezes de gato-do-mato-pequeno (Leopardus tigrinus) e maritacas (Pionus maximiliani). Cistos de Giardia foram identificados nas fezes de um veado catingueiro (Mazama gouazoubira). Entre os parasitas mais comuns, foram encontrados ovos de Toxocara cati, Toxascaris leonina e Ancylostoma tubaeforme, além de ovos de Cestoda. Vários ovos de Enterobius sp. foram encontrados nas fezes de bugio (Alouatta seniculus). Neste trabalho concluiu-se que, apesar de pequeno o número de amostras, a diversidade de parasitas encontrados foi relevante. Informa es adicionais sobre a endofauna parasitária em animais silvestres s o necessárias, pois podem sugerir a intera o e proximidade com animais domésticos e/ou o homem. Além disso, maiores est

Abstract: Neste estudo, analisaram-se os efeitos da radia o UV-C sobre odesenvolvimento de folhas de Rapanea ferruginea. Plantas jovens foram selecionadas com seis meses de idade identificando-se as folhas já diferenciadas do 3o, 4o, 6o, 8o e 9o nó. Posteriormente, as plantas foram divididas em três grupos e submetidas à radia o UV-Cpor 30, 60 ou 120 min. seguidos. Para o estudo anat mico, foram utilizadas técnicas usuais de corte e colora o. As análises morfométricas foram realizadas determinando-se três pontos ao longo da nervura central da folha, medindo-se das bordas esquerda (E) e direita (D) até cada um desses pontos. Determinaram-se também os desvios de simetria, o comprimento e a largura máxima do limbo, submetendo os valores à Anova e ao teste de Tukey (p < 0,05). As respostas de R. ferruginea à UV-C foram expressas por varia es nasimetria, bem como por injúrias morfoanat micas, sobretudo ao parênquima pali ádico e mesofilo. A diferencia o das folhas n o seguiu um padr o morfométrico, caracterizando, assim, uma assimetria n o-direcional, ou seja, flutuante. Este estudo ressalta a importanciade observa es multiescalares para a determina o de respostas de plantas ao estresse, já que algumas folhas apresentaram danos anat micos, porém n o morfológicos. This study analyzed the effects of UV-C radiation on the development of Rapanea ferruginea leaves. Young plants were selected at six months of age, previously identifying the leaves that had already differentiated on the 3rd, 4th, 6th 8th and 9th nodes. After the selection, the plants were divided into three groups and subjected to UV-C radiation for 30, 60 or 120 minutes. The anatomic study wasmade by using usual techniques of cut and coloration. The morphometric analyses were made by determining three points on the midvein of the leaf, measuring from left (L) and right (R)borders to each of those points. The symmetry deviations, maximum length and width of the limb were measured and the values were submitted to Anova and the Tukey-test (p < 0.05). The responses of R. ferruginea to the UV-C were expressed by variations in the symmetry aswell as morphoanatomic injuries, mainly in the palisade parenchyma and mesophyll. The differentiation of leaves did not follow a morphometric pattern, characterizing no directional asymmetry, i.e., fluctuating asymmetry. This study emphasizes the importance of multiscale observations for the determination of plant responses under stress, since several leaves showed anatomic injuries but no morphologic injuries.
Developing Standards for Language Teacher Education Programs in Indonesia: Professionalizing or Losing in Complexity?
Luciana Luciana
TEFLIN Journal , 2004,
Abstract: Setting standards for language teacher education programs, materials, and evaluation sparks some hope in attempts to improve the quality of the programs. Yet, this very fact augmented by my examination of ten language teacher education programs in Java, Bali, and Lampung (FKIP and PGRI) triggers a critical look at the idea of standard development. In particular, I would like to explore whether it can lead to a better professionalism or we are just lost in the complexity of the standardization itself. This paper consists of four sections. Departing from an overview of language teacher education programs in Indonesia and the theoretical foundations, some major problems in this area are identified. Following this, the discussion is focused on the idea of standard development for language teacher education programs in Indonesia. Eventually, some suggestions are put forth to highlight the need for establishing coherent curriculum framework bridging the two realms of language teacher education and school milieu as well as providing learners with knowledge base that enables them to cope with complex demands of school settings and more essentially, to act as an agent in the social change process.

Monitoring the Short-Term Response to Salt Exposure of Two Genetically Distinct Phragmites australis Clones with Different Salinity Tolerance Levels  [PDF]
Luciana Achenbach, Hans Brix
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.58122
Abstract:

Aims: Two genetically distinct clones of Phragmites australis were used to investigate the immediate response induced by osmotic stress. The study aimed at elucidating if the response time, the inhibition rate and the recovery from salinity stress vary between these two genotypes. The experimental work was conducted at the laboratory of the Institute of Bioscience, Aarhus University, Denmark. Methods: The light-saturated photosynthetic rate (Pmax), stomata conductance (gs) and transpiration rate (E) were measured over different periods of salt exposure (15, 70 and 240 minutes) and at different salt concentrations (20 and 40 parts per thousand salinity). Important findings: The osmotic stress induced stomata closure and reduction of Pmax and E for both clones. The clone-specific responses as measured through physiological parameters were negatively

Multidisciplinary Approach to a Recovery Plan of Historical Buildings
Luciana Orlando
International Journal of Geophysics , 2011, DOI: 10.1155/2011/258043
Abstract: The paper emphasizes the advantages of employing multiple data techniques—geology, GPS, surveys of cracking, boreholes, seismic refraction and electrical resistivity tomography—to image the shallow stratigraphy and hypothesize the cause of instability of an urban area. The study is focused on the joint interpretation of the crack pattern, topographic monitoring and the features of the underground, to define the area affected by instability and the direction of ground motion with the objective to advance a hypothesis on the cause of the instability of the area and to depict the main features. Borehole stratigraphies for a univocal interpretation of the lithology of electrical and seismic data and electrical resistivity tomography to constrain the interpretation of the lateral velocity variations and thickness of seismic bedrock were used. The geophysical surveys reveals to be complementary in the depicting of underground features. The study is approached at small and medium scale.
La migración en la unidad doméstica: un estudio de caso en dos municipios de la frontera argentino-boliviana (Los Toldos, Salta y Padcaya, Tarija)
Nicola,Luciana;
Mundo agrario , 2008,
Abstract: this paper studies regional and international migration in a context of peasant economies, in the border between actual municipalities of los toldos (salta, argentina) and padcaya (tarija, bolivia). it was not until 1938 that los toldos valley was officially transferred from bolivia to the argentine province of salta. from that date on, the state influences have introduced divergences between both sectors, mostly due to the differential politics that both nations have been adopting. the ethnographic study and, particularly, the comparative analysis of 110 semi-structured surveys, which allow studying the household's members' dynamics, permits us conclude that the different types of migration are structured owing to reproductive strategies of the household. permanent migration is thought as a compensatory mechanism for the redistribution of productive resources between sons, as the land subdivision is a problem nowadays, while temporary migrations are thought as another economic activity among the already conventional productive ones in the region.
