Given the steady increase in use of alternative energy sources to supply part of the energy demand of the world, and considering that mexico has enough wind resources to produce all the electricity required by the country, in this work, it is carried out the development of a system of wind resource assessment to determine the volume of water that a windmill pumping system can provide in a specific area. To this end, it has developed a computer program for wind resource assessment by measurements of wind speed, direction, temperature, barometric pressure and relative humidity. measuring equipments were mounted in a wind measurement tower of 10 m high, within the premises of the University of quintana roo which is located along the coast. Until this day, there are records over a period of five months of the variables of wind speed, wind direction, temperature, relative humidity and atmospheric pressure. These variables were used for statistical calculations using the Weibull distributions. To give a better use of the calculated data, they were applied to the evaluation of a Pumping System.

rare earths have been extensively developed in recent years, however, new hosts allow high excitation and emission efficiency, in this sense, gadolinium vanadate has been extensively studied and in previous works it has been widely used in down conversion systems. Because of the strong absorption of the VO4 groups and efficient energy transfer from GdVO4 to lanthanide ions, in this work its up-conversion properties were studied when is co-doped with Yb3+, X3+ where X = Tm, Er and Ho. The powders synthesized presented a high crystallinity and a rounded morphology and exhibit a high luminescence when are excited with Ir radiation.

The first search for the doubly heavyΩ^(0)_(bc)baryon and a search for the E^(0)_(bc)baryon are performed using pp collision data collected via the LHCb experiment from 2016 to 2018 at a centre-of-mass energy of 13 TeV,corresponding to an integrated luminosity of 5.2 fb^(-1).The baryons are reconstructed via their decays to Λ^(+)_(c)π^(-)and E^(+)_(c)π^(-).No significant excess is fbund for invariant masses between 6700 and 7300 meV/c^(2),in a rapidity range from 2.0 to 4.5 and a transverse momentum range from 2 to 20 meV/*** limits are set on the ratio of the Ω^(0)_(bc)and E^(0)_(bc)production cross-section times the branching fraction to Λ^(+)_(c)π^(-)(E^(+)_(c)π^(-))relative to that of the Λ^(0)_(b)(E^(0)_(b))baryon,for different lifetime hypotheses,at 95%confidence *** upper limits range from 0.5 x 10^(-4)to 2.5 x 10^(-4)for theΩ^(0)_(bc)→Λ^(+)_(c)π^(-)(E^(0)_(bc)→Λ^(+)_(c)π^(-))decay,and from 1.4x 10^(-3)to 6.9 x 10^(-3)for theΩ^(0)_(bc)→E^(+)_(c)π^(-)(E^(0)_(bc)→E^(+)_(c)π^(-))decay,depending on the considered mass and lifetime of theΩ^(0)_(bc)(E^(0)_(bc))baryon.

Experimental-Biological model of Bartonellosis

引用

Journal of Pharmacy and Pharmacology 2017年第6期5卷 374-378页

作者： A. V. Bondarenko S. I. Pokhil D. V. Katsapov V. m. Kozko Department of Infectious Diseases National Medical University Kharkiv 61022 Ukraine Laboratory of New and little explored Infection Mechnikov Institute of Microbiology and Immunology Kharkiv 61057 Ukraine

Bartonella are known to be important causes ofzooanthroponotic diseases. The range of human infection varies from mild lymphadenopathy and asymptomatic bacteremia to life-threatening systemic disease in immunocompromised patients. microbiological improvements in isolation methods and PCr amplification of organism-specific DNA sequences have resulted in a dramatic increase in reports describing human patients with bartonellosis. Nevertheless, clearly and successful isolation ofBartonella spp. from bacteremic animals and human patients remains an ongoing challenge. Technology of experimental bartonellosis due to intraperitoneal introduction of biological material samples containing causative agents to laboratory animals is presented in the article. White nonlinear mice with the artificially cyclophosphamide formed immunodeficient state may be used as an experimental model for further investigation of the biological alterations responsible for angiomatosis. On the other hand, we believe that this new method will enhance the diagnostic sensitivity and specificity needed to achieve a diagnosis of bartonellosis.

Background. The larvae of the botfly Dermatobia hominis cause furunculoid myiasis in endemic areas. Lack of knowledge of this condition outside these areas leads to confusion in diagnosis and delays appropriate treatment. Objective. To describe the clinical findings of furunculoid myiasis encountered in quintana roo, in the south-east of mexico. materials and methods. We performed an observational study on 25 cases diagnosed over a period of 4 years. results. Diagnosis of furunculoid myiasis was made in 14 males and 11 females with an average age of 24.5 years. most of our patients were students, farmers, or housewives. The number of lesions varied from one to four. In 20% of cases, more than one parasite was present in each lesion. The scalp was the most commonly affected region (40% ), followed by the trunk and the extremities. Doppler ultrasound study (DUSG) of the furuncle- like lesions confirmed the clinical diagnosis in all cases. Conclusions. Furunculoid myiasis is frequent in the state of quintana roo, mexico. We found no association with occupation, gender, social background or age. DUSG can be used to evaluate the number of parasites per furunculoid lesion avoiding misdiagnoses and treatmentdelays.

Flame Thermal Spray (FTS) coatings frequently show some porosity and reduced adherence to substrate, which affect its properties, especially its corrosion resistance. In this work, the corrosion resistance of AISI 1018 carbon steel coated by different methods is compared: electroless nickel (EN) coating, NiCrFeBSi obtained by FTS, duplex coatings of an EN deposit on a layer of NiCrFeBSi obtained by FTS and a layer of NiCrFeBSi on an EN deposit. The coatings were characterized using optical microscopy and scanning electron microscopy techniques, EDS microprobe microanalysis, roughness as well as electrochemical polarization tests to obtain the corrosion rate. The results show the enhancement in the corrosion resistance in saline medium of the duplex coatings, especially of the EN coating on FTS layer.
