Indium zinc oxynitride (IZON) thin films were deposited on Si(100) substrates by RF reactive magnetron sputtering at different substrate temperature to study their structural and optical properties. All the films were deposited in a reactive atmosphere of nitrogen and argon. As precursor material, an IZO target (In 2 O 3 -ZnO, 90-10 wt%) with a purity of 99.99% was used. The crystalline structure of the films was analyzed by X-Ray diffraction technique (XRD), the deposited IZON thin films were practically amorphous with some polycrystalline contents for the films deposited at 100 °C and 300 °C. The refractive index and the extinction coefficient had been obtained from Spectral Ellipsometry (SE) analyses using the Classical and Adachi models, both results were qualitatively and quantitatively approximate. These optical results were analyzed and used to propose roughness values of the films surface, through of an appropriate proposal of the structure of the films. The roughness values obtained from optical models were compared with the morphological results studied by Atomic Force Microscopy (AFM), and the roughness values, obtained by direct and indirect measure, were consistent between them. The incorporated nitrogen reduced the typical crystallization of IZO and favored the deposition of transparent thin films with very flat surfaces, these results shows that the IZON has an ideal amorphous material for applications as conductive oxynitride layers.

A study of the phase transitions in superconducting thin films of the Thallium-Barium-Calcium-Copper (TBCCO) system is carried out. In particular, it was got the Tl-1223 phase. For this purpose, and using the ultrasonic spray pyrolysis technique, Barium-Calcium-Copper precursor films were first obtained. Upon deposition of the precursor films, and as a second step, they were thallium (Tl) diffused in the one-zone furnace at 860°C. This methodology resulted in superconducting films that showed a phase transition as follows: Tl-2223 → Tl-2223 + Tl-2212 → Tl-2212 → Tl-1223, achieved between 2 and 7 hours of thallium diffusion. The evidence of the phase transitions was corroborated by the experimental results of X-ray diffraction, energy dispersive spectroscopy and resistance-temperature measurements.

Edible films were prepared with whey protein incorporating candelilla wax,and glycerol in aqueous solution.Tarbush polyphenols were added as bioactive agent.An optimization based on the water vapor permeability(WVP)of the formulation was performed using a Box-Behnken design.The films were characterized by the determination of WVP,moisture,solubility,color,antioxidant and antifungal activity.Scanning electron microscopy(SEM)was also performed to observe the surface and cross-section micrographs.The lowest permeability values were found with concentrations of 1.27,0.3 and 0.5% of protein,wax and glycerol respectively.It was proved that the addition of polyphenols into films causes a significant effect only on solubility and transparency characteristics.Edible films have suitable properties as a barrier for the goods they could be applied on.It is proposed for use in foods such as fresh or minimally processed fruits and vegetables.

Objective: To evaluate the susceptibility of Pseudomonas aeruginosa(P. aeruginosa)in vitro to the ethanolic extracts obtained from five different Peruvian medicinal plants.Methods: The plants were chopped and soaked in absolute ethanol(1:2, w/v). The antibacterial activity of compounds against P. aeruginosa was evaluated using the cupplate agar diffusion method.Results: The extracts from Maytenus macrocarpa("Chuchuhuasi"), Dracontium loretense Krause("Jergon Sacha"), Tabebuia impetiginosa("Tahuari"), Eucalyptus camaldulensis Dehn(eucalyptus), Uncaria tomentosa("U?a de gato") exhibited favorable antibacterial activity against P. aeruginosa. The inhibitory effect of the extracts on the strains of P. aeruginosa tested demonstrated that Tabebuia impetiginosa and Maytenus macrocarpa possess higher antibacterial activity.Conclusions: The results of the present study scientifically validate the inhibitory capacity of the five medicinal plants attributed by their common use in folk medicine and contribute towards the development of new treatment options based on natural products.

The presence of El Ni?o Southern Oscillation(ENSO)implies the presence of fluctuating rains in coastal areas and these changes influence the occurrence of febrile syndromes outbreaks.In Peru,Aedes aegypti is the vector responsible for various viruses such as the dengue,Zika,chikungunya,which is distributed in 18 Peruvian departments.These viruses cause similar clinical characteristics in the host and for this reason rapid,sensitive and specific diagnostic tests are needed so that the patient can receive timely treatment.

This recycling of printed circuit board (TCI) for the production of metals, given the environmental degradation that can cause toxic substances of these, is the reuse of valuable materials recovered from the TCI, this being an economic engine that promotes the recycling of this waste. This paper presents a methodology for evaluating the reaction kinetics and leaching of metals that form the metal substrate, which have environmental and energy advantages, so the generation of new recovery techniques metals from the TCI low environmental and energy impact is increasingly necessary, for it is essential to establish the parameters affecting the reaction rate and identify design alternatives to determine whether or not sustainable, economically viable and that does not pollute. The method adopted was a leaching acid samples, where the full factorial method employed two experimental levels to evaluate the influence of: leaching time, temperature of the aqueous leach solution, reaction kinetics and solid/liquid, on the percentage of metal extraction. Subsequently, the metals are obtained by calcining and smelting the resulting salts by addition of acid liquor.

Objective:To describe and molecularly characterize an outbreak of dengue virus(DENV)infection in Cajamarca,an Andean region in Peru.Methods:A total of 359 serum samples from patients with acute febrile illness were assessed for the presence of DENV via RT-PCR,ELISA NS1,Ig M and Ig G in Cajamarca,Peru from January 2017 to June 2017.The evaluation of the different diagnostic tests and their applicability was performed.Results:Dengue virus was detected in 24.7%of samples by RTPCR.Meanwhile,serological analysis detected 30.3%positive cases via ELISA NS1 antigen,16.7%via ELISA Ig G and 9.7%via ELISA Ig M.Most of the cases corresponded to DENV-3(77.5%).The use of RT-PCR performed better in primary infections(P<0.01),while detection of ELISA Ig M performed better in secondary infections(P<0.01).The combination of NS1 and Ig M performed better than the other assays in detecting primary(92.5%)and secondary infections(96.6%).The most frequent symptoms associated with fever were headaches,myalgias,and arthralgias across all groups.Conclusions:We report an important outbreak of dengue infection caused by DENV-3 in Cajamarca,Peru.Our findings encourage the use of NS1 antigen and Ig M co-detection.These findings demonstrate an increasing expansion of DENV-3 in Peru and highlight the importance of molecular diagnosis and serotype characterization among the clinically defined dengue cases to strengthen the Peruvian epidemiological surveillance.

我们在西班牙南部的一个卫生保健地区开展了一项为期1年的Ⅱ型糖尿病病人卫生资源消耗的描述性与观察性研究。总共对517名患者进行了评估,患者的平均发病时间为(9.7±8)年。每一名患者每年总成本为4278欧元,其中直接成本2504欧元,间接成本1774欧元。多元回归分析显示,总成本与以下变量之间独立相关:肥胖、性别、糖尿病相关住院次数、永久残疾、大血管并发症,以及微血管和大血管并发症同时发生。我们的研究结果一方面证实了Ⅱ型糖尿病治疗高昂的经济成本,另一方面也证实了糖尿病的疾病经济成本与肥胖、性别、糖尿病相关住院次数、永久残疾和慢性并发症等因素之间的直接关系。
