CCl4 （carbon tetrachloride） and n-C6H14 （n-hexane） sorption studies have been carried out on natural and dealuminated clinoptilolite-type zeolites. External surface area of the materials has been assessed using the αs-plots method. The high resolution αs-plots show that the isotherms are divided into four parts corresponding to adsorption in ultramicropores, intersections, supermicropores and external surface area, respectively. The mineralogies of natural zeolites are determined by X-ray analysis. N： low-pressure hysteresis loops, displayed by some substrata, are related to the micropore structure and to the ion-exchange treatment at which the natural precursors were subjected. The adsorption behavior of these substrata was examined in the range of relative pressures between 10^-5-1. Natural samples were used as reference materials to carry out the sorption analyses of the dealuminated samples. The effect of narrow micropore constrictions on the adsorption behavior of clinoptilolites was explored. The occurrence of a low-pressure hysteresis loop on the sorption isotherm of a modified sample is associated to the strong adsorption of the adsorbate molecules at the entrance of the necked-shape micropores, which interfere with the diffusion of the adsorbate molecules inside the porous structure.

Adsorption isotherms of N2 and 02 on dealuminated clinoptilolite zeolites were measured by the inverse gas chromatography method at zero-coverage. This type of microporous solids such as natural （CLINA） and dealuminated clinoptilolite zeolites （CLIDA1-CLIDA5） were conditioned by means of acid treatment of the natural zeolitic precursor （CLINA） with HCI at different concentration. Adsorption of selected gases （N2 and 02） on clinoptilolite zeolites were studied in the temperature range from 398 K to 498 K. The Langmuir adsorption model was found to approximately fit the gases adsorption data, within the selected temperature range. The uptake amount of these gases by the diverse adsorbents was temperature dependent. Additionally, the energies of interaction between of these gases with clinoptilolite microporous walls were realized from the evaluation of the isosteric heats of adsorption （qst）. These isosteric heats were found to obey in the following decreasing order： qst （N2）： CLIDA1 〉 CLIDA3 〉 CLIDA2 〉 CLIDA4 〉 CLIDA5 〉 CLINA; while qst （02）： CLIDA3 〉 CLIDA2 〉 CL1DA1 〉 CLIDA5 〉 CLIDA4 〉 CLINA.

Physiological and Molecular Characterization of <i>Malassezia pachydermatis</i>Reveals No Differences between Canines and Their Owners

引用

Open Journal of Veterinary Medicine 2018年第7期8卷 87-105页

作者： Juan Camilo Galvis Marín fernando Borda rojas Andrés Julián Gutiérrez Escobar Group of Biological Investigations and Applied Genetics (GIBGA) Faculty Health Sciences Universidad de Ciencias Aplicadas y Ambientales (UDCA) Bogotá Colombia Animal Science Research Group Faculty of Animal Sciences Universidad de Ciencias Aplicadas y Ambientales (UDCA) Bogotá Colombia

Introduction: The genus Malassezia comprises 17 species of commensal and pathogenic yeasts of homeotherms animal skin. The most common species are M. furfur, M. globosa, and M. sympodialis in humans and M. pachydermatis in animals. However, some publications have reported potentially serious human infections by M. pachydermatis in individuals with risk factors and the isolation of human species from domestic animals. Given the scarcity of information about their capacity for transmission between hosts and zoonotic potential, the aim of the present study was to physiologically and molecularly characterize Malassezia spp. isolates obtained from canines and their human owners. Materials and Methods: An experimental study was conducted at the Veterinary Clinic of Universidad de Ciencias Aplicadas y Ambientales of Bogotá (Colombia) from July 2015 to December 2016. Phenotypic identification and molecular characterization via the amplification of the 5.8S rDNA- ITS2 and 26S rDNA gene regions, nucleic acid sequencing, and phylogenetic analyses were performed on isolates originating from canines with otitis externa and from the skin of healthy owners compatible with Malassezia spp. Results: Eighty samples were cultured, of which 32 (40%) were suggestive of Malassezia spp. A total of 29 out of 46 (63%) isolates in canines and 3 out of 34 (9%) isolates in humans corresponded entirely with M. pachydermatis. Isolates from the canines and their owners presented similar behavior in biochemical and phospholipase activity tests, 100% molecular sequence identities, and close proximity in the phylogenetic trees. Conclusion: The isolation of M. pachydermatis from humans and their dogs with identity based on biochemical, physiological, molecular, and phylogenetic perspectives indicate the ability of this species to adapt to new hosts and its potential for zoonotic transmission. These findings contribute to knowledge of the ecology of this important fungus in human and veterinary medicin

Sickle Crisis Precipitated by Pneumonia: A Diagnostic and Therapeutic Challenge

Sickle cell anemia (SCA) is a prevalent genetic disorder primarily affecting individuals of African descent and populations in malaria-endemic regions, with significant global public health implications. Sickle cell crises are their most common acute complication, characterized by episodes of intense pain and systemic manifestations that impair quality of life and impose a high healthcare burden. We present the case of a 19-year-old male diagnosed with SCA since the age of two, who developed a sickle cell crisis precipitated by right basal pneumonia. The patient exhibited sudden-onset, cyclic lumbar pain with progressive dyspnea. Initial management included multimodal pain control, volume optimization, and targeted antimicrobial therapy to achieve clinical stabilization. This case underscores the importance of a comprehensive approach to managing sickle cell crises, addressing both symptomatic relief and the prevention and treatment of complications. It also highlights the need for public health strategies promoting early diagnosis, access to disease-modifying therapies such as hydroxyurea, and interdisciplinary follow-up to mitigate the socioeconomic and clinical impact of SCA.

An Approach to Design MIMO FO Controllers for Unstable Nonlinear Plants

引用

IEEE/CAA Journal of Automatica Sinica 2016年第3期3卷 338-344页

作者： Arturo rojas-Moreno IEEE Department of Electrical Engineering Universidad de Ingenieriay Tecnologia (www.utec.edu.pe)

This paper develops an approach to control unstable nonlinear multi-inputs multi-output(MIMO) square plants using MIMO fractional order(FO) controllers. The controller design uses the linear time invariant(LTI) state space representation of the nonlinear model of the plant and the diagonal closedloop transfer matrix(TM) function to ensure decoupling between inputs. Each element of the obtained MIMO controller could be either a transfer function(TF) or a gain. A TF is associated in turn with its corresponding FO TF. For example, a D(Derivative) TF is related to a FO TF of the form Dδ, δ =[0, 1]. Two applications were performed to validate the developed approach via experimentation: control of the angular positions of a manipulator, and control of the car and arm positions of a translational manipulator.
