Published: April 2019

Los bosques de la Amazonia peruana han experimentado importantes transformaciones desde mediados del siglo pasado. Este trabajo evaluó los Cambios de Cobertura y Uso del Suelo (CCUS) en la provincia de Rodríguez de Mendoza, mediante los métodos de clasificación supervisada de máxima probabilidad e interpretación visual interdependiente de imágenes del satélite Landsat, entre los períodos 1987–2001 y 2001–2016. Se construyeron matrices de tabulación cruzada y se calcularon tasas e índices anuales de cambio. Los resultados muestran una pérdida acumulada de 918,59 km2 de cobertura boscosa. La intensidad de CCUS y la tasa de deforestación fueron mayores en el segundo período de análisis. Se evidenció que las altas concentraciones de pérdida de cobertura boscosa están próximas a la red vial e hídrica. Las principales causas de la pérdida de bosques fueron la actividad ganadera y la expansión agrícola migratoria a pequeña explotación, favorecidas por la accesibilidad de infraestructuras de transporte.

An analysis of public sector spending on education in Pakistan and its impact on the productivity and employability of Pakistan’s human resource
Authors: Aslam Qais
Published: April 2019

This paper reviews the budgetary expenditures on public sector education in Pakistan, its issues and impact on sectorial jab creation as percentage of GDP. It shows that there are multiple education systems in Pakistan with different medium of instruction and gender segregation at school levels and with multiple problems and inefficiencies. In addition, there are inadequate schools for boys and girls. Budgetary expenditure on Tertiary education is 35% and on school education 65%. There are 185 Universities in the country. The share of Agriculture in GDP in 2012-2018 period declined by 2.5%, of Industry declined by 6.7%, whereas the share of services sector grew by 9.2% increasing job opportunities in the new knowledge based economy at the cost of manufacturing sector. 

Government should built more schools at all levels with modern facilities and infrastructures even at remotest corners of the country. There should be scientific upgradation of teachers at all levels. Textbooks should encourage research based gender sensitive, environment sensitive and productivity orientated scientific and technological knowledge with a more progressive worldview in order to create greater linkages between school system and Higher Education with emphasis on the knowledge economy of tomorrow that incorporates international labor and human rights standards.

Published: April 2019

Background:
Acute gastrointestinal (GI) bleeding is an important cause of mortality worldwide. Bleeding can occur from the upper or lower GI tract, with upper GI bleeding accounting for most cases. The main causes include peptic ulcer / erosive mucosal disease, oesophageal varices and malignancy. The case fatality rate is around 10% for upper GI bleeding and 3% for lower GI bleeding. Rebleeding affects 5-40% of patients and is associated with a four-fold increased risk of death. Tranexamic acid (TXA) decreases bleeding and the need for blood transfusion in surgery and reduces death due to bleeding in patients with trauma and postpartum haemorrhage. It reduces bleeding by inhibiting the breakdown of fibrin clots by plasmin. Due to the methodological weaknesses and small size of the existing trials, the effectiveness and safety of TXA in GI bleeding is uncertain. The HALT-IT trial aims to provide reliable evidence about the effects of TXA in acute upper and lower GI bleeding.

Methods:
The HALT-IT trial is an international, randomised, double blind (participant and trial staff), placebo-controlled trial of tranexamic acid in 12,000 adults (increased from 8,000) with acute upper or lower GI bleeding. Eligible patients are randomly allocated to receive tranexamic acid (1g loading dose followed by 3g maintenance dose over 24 hours) or matching placebo. The main analysis will compare those randomised to tranexamic acid with those randomised to placebo on an intention-to-treat basis, presenting the results as effect estimates (relative and absolute risks) and confidence intervals. The primary outcome is death due to bleeding within 5 days of randomisation and secondary outcomes are rebleeding, all-cause and cause-specific mortality, thromboembolic events, complications, endoscopic, radiological and surgical interventions, blood transfusion requirements, disability (defined by a measure of patient’s self-care capacity) and number of days spent in intensive care or high dependency units. Subgroup analyses for the primary outcome will consider time to treatment, location of bleeding, cause of bleed and clinical Rockall score.

Discussion:
We present the statistical analysis of the HALT-IT trial. This plan was published before the treatment allocation was un-blinded.
Reliability of pleth variability index in predicting preload responsiveness of mechanically ventilated patients under various conditions: a systematic review and meta-analysis
Authors: Liu Tianyu , Xu Chao , Wang Min , Niu Zheng , Qi Dunyi
Published: April 2019

Abstract
Background: Goal-directed volume expansion is increasingly used for fluid management in mechanically ventilated patients. The Pleth Variability Index (PVI) has been shown to reliably predict preload responsiveness; however, a lot of research on PVI has been published recently, and update of the meta-analysis needs to be completed.
Methods: We searched PUBMED, EMBASE, Cochrane Library, Web of Science (updated to November 7, 2018) and the associated references. We also contacted relevant authors and researchers.
Results: Twenty-five studies with 975 patients were included in this meta-analysis. All patients were mechanically ventilated. The area under the curve (AUC) of receiver operating characteristics (ROC) to predict preload responsiveness in patients was 0.82 (95% confidence interval (CI) 0.79 - 0.85). The pooled sensitivity was 0.77 (95% CI 0.67-0.85) and the pooled specificity was 0.77 (95% CI 0.71-0.82). The results of subgroup of patients without undergoing surgery (AUC =0.86, Youden index =0.65) and the results of subgroup of patients in ICU (AUC =0.89, Youden index =0.67) were reliable.
Conclusion: The reliability of the PVI is limited, but the PVI can play an important role in bedside monitoring for mechanically ventilated patients who are not undergoing surgery. Patients who are expanded with colloid may be more suitable for PVI.
Band-based similarity indices for gene expression clustering and classification.
Authors: Torrente Aurora
Published: April 2019

Background: The concept of depth induces an ordering from centre outwards in multivariate data. Most depth definitions are unfeasible for dimensions larger than three or four, but the Modified Band Depth (MBD) is a notable exception that has proven to be a valuable tool in the analysis of gene expression data. However, given a notion of depth, there exists no straight forward method to derive a depth-based similarity or dissimilarity measure between observations to be used in standard tasks such as clustering or classification.

Results: We propose a methodology to assess a data-driven (dis)similarity between two observations, taking advantage of the bands used in the computation of the MBD. To that end, we build binary vectors associated to each observation to compute the number of times each coordinate is located between the limits of the intervals defined by all possible bands in the set. Those vectors and their Boolean products are used to derive contingency tables from which standard similarity indices can be calculated. Our approach is computationally efficient and can be applied to bands formed by any number of observations from the data set.

Conclusions: We have evaluated the performance of several similarity indices with respect to that of the Euclidean distance, used as benchmark, in standard clustering and classification techniques in a variety of simulated and real data sets. Our experiments show that the technique for deriving such measures is very promising, with some of the selected indices outperforming the Euclidean distance. The use of the method is not restricted to these, the extension to other similarity coefficients being straight-forward.
Effect of sevoflurane on systemic and cerebral circulation, cerebral autoregulation and CO2 reactivity
Authors: Juhász Marianna , Molnár Levente , Fülesdi Béla , Végh Tamás , Páll Dénes , Molnár Csilla
Published: April 2019

Background: Sevoflurane is one of the most frequently used inhaled anesthetics for general anesthesia. Previously it has been reported that at clinically used doses of sevoflurane, cerebral vasoreactivity is maintained. However, there are no data how sevoflurane influences systemic and cerebral circulation in parallel. The aim of our study was to assess systemic and cerebral hemodynamic changes as well as cerebral CO2-reactivity during sevoflurane anesthesia.
Methods: 29 patients undergoing general anesthesia were enrolled. Anesthesia was maintained with 1 MAC sevoflurane in 40% oxygen. Ventilatory settings (respiratory rate and tidal volume) were adjusted to reach and maintain 40, 35 and 30 mmHg EtCO2 for 5 minutes respectively. At the end of each period, transcranial Doppler and hemodynamic parameters using applanation tonometry were recorded.
Results: Systemic mean arterial pressure significantly decreased during anesthetic induction and remained unchanged during the entire study period. Central aortic and peripherial pulse pressure and augmentation idex as markers of arterial stiffness significantly increased during the anesthetic induction and remained stable at the time points when target CO2 levels were reached. Both cerebral autoregulation and cerebral CO2-reactivity was maintained at 1 MAC sevoflurane.
Discussion: Cerebral autoregulation and CO2-reactivity is preserved at 1 MAC sevoflurane. Cerebrovascular effects of anesthetic compounds have to be assessed together with systemic circulatory effects.
Key words: sevoflurane; cerebral blood flow, cerebral autoregulation; CO2-reactivity, applanation tonometry; transcranial Doppler
The study was registered at http://www.clinicaltrials.gov, identifier: NCT02054143, retrospectively registered.
Advanced ultrasound Methods in assessment of carotid plaque instability: A prospective multimodal study
Authors: Zamani Mahtab , Skagen Karolina , Scott Helge , Russell David , Skjelland Mona
Published: April 2019

Background: A significant proportion of ischemic strokes are caused by emboli from atherosclerotic, unstable carotid artery plaques. The selection of patients for endarterectomy in current clinical practice is primarily based on the degree of carotid artery stenosis and clinical symptoms. However, the content of the plaque is known to be more important for stroke risk. Intraplaque neovascularization (IPN) has recently emerged as a possible surrogate marker for plaque instability. Neo-microvessels from the adventitial vasa vasorum grow into the full thickness of the vessel wall in an adaptive response to hypoxia, causing subsequent intraplaque haemorrhage and plaque rupture. Conventional ultrasound cannot detect IPN. Contrast-enhanced ultrasound and Superb Microvascular Imaging (SMI), have, however, shown promise in IPN assessment. Recent research using Shear Wave Elastography (SWE) has also reported reduced tissue stiffness in the artery wall (reduced mean Young’s modulus) in unstable compared to stable plaques. The purpose of this study is to identify unstable carotid artery plaques at risk of rupture and future ischemic stroke risk using multimodal assessments.
Methods: Thirty symptomatic and 30 asymptomatic patients >18 years, with >50% carotid stenosis referred to Oslo University Hospital ultrasound lab will be included in this on-going project. Patients will undergo contrast enhanced ultrasound, SMI, carotid-MRI and PET-(18F-FDG). Contrast enhanced ultrasound will be analyzed semi-quantitatively (5-levels of visual classification) and quantitatively by plotting time-intensity curve analyses to obtain plaque peak contrast enhancement intensity. Plaques removed at carotid endarterectomy will be assessed histologically and the number of microvessels, areas of inflammation, granulation, calcification, lipid and fibrosis will be measured.
Discussion: This multimodality study will primarily provide information on the clinical value of advanced ultrasound methods (SMI, SWE) for the detection of unstable carotid artery plaque in comparison with other methods including contrast-enhanced ultrasound, carotid-MRI and PET-(18F-FDG) using histology as the gold standard. Secondly, findings from the methods mentioned above will be related to cerebrovascular symptoms, blood tests (leukocytes, CRP, ESR, lipoproteins and inflammatory markers) and cardiovascular risk factors at inclusion and at 1-year follow-up. The overall aim is to optimize detection of plaque instability which can lead to better preventive decisions and reduced stroke rate.

Authors: Chen Zhaoyao , Zhang Shuai , Dai Zhengze , Cheng Xi , Wu Minghua , Dai Qiliang , Liu Xinfeng , Xu Gelin
Published: April 2019

Background

Patients with vertebrobasilar dolichoectasia usually have persistent hemodynamic abnormalities, and therefore, may bear an increased risk of stroke. This study aimed to evaluate ischemic stroke recurrence in patients with vertebrobasilar dolichoectasia.

Methods

Patients with acute ischemic stroke were screened and evaluated for eligibility. Enrolled patients were followed via scheduled clinical visits or telephone interviews. Ischemic stroke recurrence was proposed with clinical symptoms and confirmed with cranial Magnetic Resonance Imaging or Computerized Tomography scans. Baseline characteristics and vascular geometry were compared between patients with and without stroke recurrence. Significant parameters were introduced into COX proportional hazard model to detect possible predictors of stroke recurrence.

Results

A total of 115 stroke patients with vertebrobasilar dolichoectasia were enrolled, of which 22 (19.1%) had recurrence during 22 ± 6 months follow-up. Basilar artery diameter ≥ 5.3 mm (HR = 4.744; 95% CI, 1.718-13.097; P = 0.003), diffuse intracranial dolichoectasia (HR = 3.603; 95% CI, 1.367-9.496; P = 0.010) and ischemic heart disease history (HR = 4.095; 95% CI, 1.221-13.740; P = 0.022) had increased risk of recurrence.

Conclusions

Stroke patients with vertebrobasilar dolichoectasia may have a high risk of recurrence. Larger basilar artery diameter or diffuse intracranial dolichoectasia may increase the risk of recurrence.
Stormwater inflow loading of polycyclic aromatic hydrocarbons into urban domestic wastewater treatment plant for separate sewer system
Authors: Ozaki Noriatsu , Yamauchi Takahiro , Kindaichi Tomonori , Ohashi Akiyoshi
Published: April 2019

Polycyclic aromatic hydrocarbons (PAHs) are common contaminants present in wastewater, and determination of their sources is important for their management in the environment. In this study, stormwater loading of PAHs during rainfall periods was evaluated for sewage inflow into a wastewater treatment plant (WWTP) for a separate sewer system. To accomplish this, sewage inflow volumes, suspended solid concentrations, and PAH concentrations were measured during eight rainfall events and on two no-rainfall days at the inlet of the plant. Based on a comparison between the rainfall and no-rainfall loading quantified by the measurements, excess PAH loadings with stormwater were evaluated for the rainfall events. The relationship between rainfall intensity and stormwater loading was then used to evaluate long-term stormwater loadings of water and PAHs. Their contributions to the sewage inflow were 0.7% and 1.0% for 1 year for water and the sum of 16 measured PAHs, respectively. Our measurements and estimates demonstrate that direct stormwater inflow is not a primary source of PAHs to the plant for this separate sewer system.

Authors: Siwach Reena , Pandey Parijat , Dureja Harish
Published: April 2019

Background:

The rate-limiting step in the oral absorption of BCS class II drugs is dissolution.
Their low solubility is one of the major obstacles in the process of drug development. Dissolution
rate can be increased by decreasing the particle size to the nano range, eventually leading to increased
bioavailability.

Objective:

: In the present study, glimepiride loaded nanoparticles were prepared to enhance the dissolution
rate. The aim of the work was to examine the effect of polymer-drug ratio, solvent-antisolvent ratio and
speed of mixing on in vitro release of glimepiride.

Methods:

Glimepiride is an antidiabetic drug belonging to the BCS class II drugs. The polymeric nanoparticles
were formulated according to Box-Behnken Design (BBD) using nanoprecipitation technique. The
prepared nanoparticles were evaluated for in vitro drug release, loading capacity, entrapment efficiency,
and percentage yield.

Result:

It was found that NP-8 has maximum in vitro drug release and was selected as an optimized
batch. Analysis of Variance (ANOVA) was applied to the in vitro drug release to study the fitness and significance
of the model. The batch NP-8 showed 70.34 ± 1.09% in vitro drug release in 0.1 N methanolic
HCl and 92.02 ± 1.87% drug release in phosphate buffer pH 7.8. The release data revealed that the nanoparticles
followed zero order kinetics.

Conclusion:

The study revealed that the incorporation of glimepiride into gelucire 50/13 resulted in enhanced
dissolution rate.

Published: April 2019

A feeding trial to study the effect of slow release non-protein nitrogen compound was conducted for 180 days in twelve early lactating Gir and crossbred cows that were divided into two equal groups viz., T0 (Control) and T1 (treatment). T0
received farm made concentrate mixture and T1 received concentrate mixture containing 1% SRNPN (Slow release non-protein nitrogen compound). The animals in both the groups were fed mixed hay as dry roughage and paragrass as green roughage. Dry matter
intake in T0 and T1 was comparable. The average daily milk yield, 4% FCM yield, TDN and DCP intake of cows inT1 was significantly (P less than 0.01) higher than T0. The efficiency in terms of DM, TDN and DCP required per kg FCM were significantly (P
less than 0.01) better in T1 than T0. The specific gravity, milk protein, solids not fat, total solids and total ash contents of milk were comparable in both the experimental groups, however, the average milk fat percentage in T1 was significantly (P
less than 0.01) higher than T0. Digestibility coefficients of all the nutrients were higher in SR-NPN supplemented group than SR-NPN non-supplemented feed. Profit realized per day over feed cost per cow was higher in T1 (Rs.108.34) than T0 (Rs.
90.29). It can be inferred that efficient utilization of poor quality roughages, better productivity and higher profit margin can be achieved by inclusion of SR-NPN at 1 percent level in the concentrate mixture of lactating cows.

Authors: Setyawaty Rety , Feriadi Feriadi , Dewanto Dewanto
Published: April 2019

Cream is a semi-solid emulsion dosage form of both water-in-oil (W/O) or oil in water (O/W) type containing one or more dissolved or dispersed ingredients in the corresponding base material (containing no less than 60% water). Cream is usually used as emollient or containing active pharmaceutical ingredients on the skin (Ansel, 2008). The advantage of cream are the application practicallity, water washeability, and the easiness to spread evenly. In this research, we formulated cream containing rhizome Galangal rhizome. According to Darmono (2008), Galangal rhizome has various properties such as antifungal and antibacterial activities. Galangal rhizome contains 1-asetoksikhavikol asetat (ACA). ACA is an antifungal. ACA has good solubility in 70% ethanol. We maserated Galangal rhizome (Alpinia galangal L.) to extract ACA from the simplicia. As for the cream base, we use hidrophilic base containing emulgators stearic acid and triethanolamine, with glycerin as humectant. During the optimization, we chose three formulas, formula 1 (10% stearic acid , 2% triethanolamin, 5% glycerin, and 0.01% vitamin E), formula 2 (15% stearic acid , 3% triethanolamin, 10% glycerin, and 0.05% vitamin E), and formula 3 (20% stearic acid, 4% triethanolamin, 7.5% glycerin, and 0.09% vitamin E). We used the bases to contain 10% of the extract. The results show that formula 1, formula 2, and formula 3 had typical smell of Galangal rhizome, brown color, and thick consistency. All formulas are homogenous. Formula 1 the best stability. We conclude that Galangal rhizome (Alpinia galanga L.) can be formulated in cream form with our formula 1 had the best stability among others.

Published: April 2019

Circular thin walled structures have wide range of applications. This type of structure is generally exposed to different types of loads, but one of the most important types is a buckling. In this work, the phenomena of buckling was studied by using finite element analysis. The circular thin walled structure in this study is constructed from; cylindrical thin shell strengthen by longitudinal stringers, subjected to pure bending in one plane. In addition, Taguchi method was used to identify the optimum combination set of parameters for enhancement of the critical buckling load value, as well as to investigate the most effective parameter. The parameters that have been analyzed were; cylinder shell thickness, shape of stiffeners section and the number of stiffeners. Furthermore, to verify the contribution of parameters on buckling response, the analysis of variance technique (ANOVA) method was implemented, which gave the contribution weight as percentages. The analysis of results by these two methods showed that the more effective parameter on the critical buckling load was the thickness of cylinder’s shell and the lowest effective was the number of stiffeners The values of parameters that gave the best critical buckling load combination were: 1) the ratio of cylinder’s diameter to thickness of its shell was 133, 2) the ratio of the depth to thickness of stiffeners was1.6, and 3) the number of stiffeners was 12.

El desempeño térmico de construcciones es un factor importante para hacer más confortable y económica una vivienda, mejorando la calidad de vida. Un análisis del confort térmico en un edificio comprende los materiales utilizados para componer su envoltorio. Este trabajo desarrolló una comparación de la resistencia térmica y de la transmitancia térmica de paredes con bloques de hormigón convencional, y hormigón ligero con vermiculita y con EPS (poliestireno expandido). También fueron evaluados los cálculos relacionados a la cobertura. La transmitancia térmica y la capacidad térmica de las paredes y de las coberturas fueron analizadas de acuerdo con la norma NBR 15220 y el Programa Nacional (Brasileño) de Conservación de Energía Eléctrica – Procel, considerando los niveles A (más eficiente), B, C, D y E. Para ambientes acondicionados solamente las coberturas de hormigón con vermiculita se adecuan a los requisitos previos del Procel en el nivel B (transmitancia térmica < 1.5W/ m²K). Fue calculada la transmitancia térmica para clasificar según las exigencias para paredes externas (transmitancia térmica < 3.7W/m², según Procel). Se concluyó que las coberturas y paredes (bloques) que utilizaron hormigón ligero han proporcionado mejor desempeño térmico a la construcción cuando comparadas con las coberturas y paredes (bloques) que utilizaron hormigón ordinário.

Introducción: las infecciones nosocomiales son aquellas adquiridas por los pacientes durante la hospitalización. Son de gran importancia en medicina humana pero aún se desconoce cuál es su papel en medicina veterinaria.Objetivo: identificar la presencia de bacterias asociadas a infecciones hospitalarias en ambientes y superficies en una clínica veterinaria.Materiales y métodos: se realizaron dos muestreos, se determinó a través de sedimentación y torunda la presencia de bacterias en el ambiente y las superficies de las 8 unidades de la clínica veterinaria. La presencia de nosocomiales se determinó por el crecimiento y purificación en medios diferenciales, la identificación se hizo por descripción macroscópica de las colonias y tinción de Gram y posteriormente se realizó una caracterización bioquímicamente por medio del API20E y API50 CH/E y un antibiograma en las cepas relacionadas con resistencia a antibióticos.Resultados: se obtuvo 95 aislados y se logró determinar la presencia de 28 agentes potencialmente nosocomiales, donde se destaca la presencia de Pseudomonas aeruginosa, Proteus sp. y Staphylococcus sp. microorganismos relacionados con infecciones asociadas a hospitales veterinarios.Conclusiones: se realiza la primera aproximación a este tipo de infecciones en hospitales veterinarios en Antioquia, y se evidencia la circulación en ambiente y superficies de potenciales bacterias nosocomiales en la clínica veterinaria.

Introducción. La Bronquiolitis secundaria al Virus Sincitial Respiratorio, se han asociado con episodios sibilantes recurrentes y desarrollo de asma, incluso en la adultez. Sin embargo, la relación entre estas patologías es controvertida, y aun no se conoce el comportamiento de este fenómeno en Colombia. El objetivo de este estudio fue describir la evolución clínica a cinco años, de los niños con antecedente de bronquiolitis que requirieron hospitalizaciónMateriales y métodos. Estudio descriptivo de cohorte retrospectiva de menores de dos años, con diagnóstico de Bronquiolitis atendidos en la Clínica Universitaria Colombia en los años 2008 a 2011 con seguimiento de hospitalizaciones por patologías respiratorias hasta el año 2016. Se revisaron 306 historias clínicas de pacientes y se analizaron características socio- demográficas, aislamientos virales y manejo farmacológico.Resultados. Los años con mayor número de hospitalizaciones por episodios sibilantes posterior al episodio bronquiolitis fueron el 2009 y 2011 con una incidencia acumulada de 15,6% y 9,9%. La edad promedio de hospitalización fue 6 meses y más frecuente en hombres. El virus sincital fue aislado con mayor frecuencia en los años de seguimiento, y la mayoría de los casos requirió manejo antibiótico; la ampicilina sulbactam (28,5%) y la ampicilina (22,6%).

Background: In the diagnostic process of pleural tuberculosis, the findings from video-assisted thoracoscopy (VATS) can be highly suggestive for the diagnosis of infection.Methods: We reviewed VATS records between the years 2012 to 2016 of patients over 16 years of age with pleural effusion and suspected pleural tuberculosis. Symptoms, macroscopic and chemical characteristics of the fluid, surgical descriptions and visual diagnosis of the surgeon were recorded and were compared with the histopathology.Results: 106 patients were selected, most of them men (71.7%), of whom approximately half were active military (51.3%). The predominant symptoms were dyspnea, pleuritic pain, fever and evolution time greater than 15 days (94.3%, 80.2%, 50% and 46,2%, respectively). These symptoms, in turn, were present more frequently in pleural tuberculosis patients than in non-tuberculosis patients. The fluid was mostly turbid yellow (44%) and lymphocytic cellularity exudate (77.4%). The VATS findings in patients with confirmed TBC included nodules (96.9%), adhesions (87.5%) and thickening (78.1%). The diagnosis made by the surgeon in relation to the histopathological diagnosis showed a sensitivity of 88.6% and a specificity of 98.4%.Conclusion: There are highly suggestive characteristics of the macroscopic report of VATS that would allow a quicker diagnosis of pleural tuberculosis.

Se realizó el aislamiento de cepas queratinolíticas en. suelos de pradera de cuatro sectores lindantes entre sí, destinados a: 1) cultivos alternantes de trigo y soja; 2) potreros con ganado vacuno y caballar; 3) corral de aves y 4) corral de cerdos.De los resultados obtenidos en muestras de potreros y corrales, se aprecia una marcada selección de las especies queratinolíticas, aparentemente condicionadas al tipo de sustrato queratinoso aportado por los distintos animales. En suelos de porquerizas, hay un predominio de Keratinomyces ajelloi, mientras que en los correspondientes a potreros, tiene la mayor frecuencia el complejo Microsporum gypseum y sus teleomorfos. En corral de aves, Arthroderma ciferril y su anamorfo fueron aislados por primera vez en nuestro país.Cabe destacar que en suelos destinados a cultivos, sin el especial aporte queratinoso, todas las muestras presentaron desarrollo de K. ajelloi.

Published: April 2019

A pesquisa aqui relatada versa sobre a busca pela implementação de um laboratório virtual de Geometria dentro do metaverso OpenSim. Tendo em vista as limitações no que se refere aos objetos oferecidos pelo metaverso e à fluência necessária em programação para que seja possível o desenvolvimento de objetos para o OpenSim, foram exploradas ferramentas de autoria como recursos alternativos para se promover um desenvolvimento facilitado de objetos, que não requeira conhecimentos avançados em programação.Atualmente, tem-se explorado o Google SketchUp para a elaboração de objetos 3D a serem incorporados no metaverso com o apoio do viewer Firestorm. Em paralelo às pesquisas técnicas, foi desenvolvida uma estrutura pedagógica que define a forma como o laboratório deverá funcionar, com diferentes ambientes, objetos e atividades a serem realizadas.
