An investigation of hydrotalcite-derived ternary Mg-Al-Ce oxides as catalysts for vapour phase condensation of ethanol to 1-butanol in a flow reactor under atmospheric pressure was carried *** Mg-Al-Ce oxide systems with Mg/(Al+Ce)ratio from 1 to 4 were synthesized and characterized by XRD,SEM,NMR,and *** study of acid-base characteristics of the systems with different Mg/(Al+Ce)ratio by NH3/CO_(2)quasi-equilibrium thermal desorption techniques shows that the ratio of the catalyst oxide components(Mg,Al,Ce)can provide acid/base capacity ratio close to 3 for the effectivity of the target *** highest selectivity 68%is reached over Mg-Al-Ce oxide catalyst with the ratio of Mg/(Al+Ce)=2.

Li-rich layered oxide(LLO),e.g.,Li_(1.12)[Mn_(0.56)Ni_(0.16)Co_(0.08)]O_(2)(LRMO),is considered as a promising cathode material due to its superior Li-storage ***,the poor cycling stability and large voltage decay,which are related to the phase transition,limit its industrialization ***,a Mo-doped LRMO(Li_(1.12)[Mn_(0.56)Ni_(0.16)Co_(0.08)]_(0.98)Mo_(0.02)O_(2),LRMO-Mo2.0%)was successfully synthesized via a simple combination of co-precipitation with high-temperature calcination for solving the mentioned *** with the pristine counterpart,the as-prepared LRMO-Mo2.0%shows more excellent electrochemical performance in terms of rate capability(reversible capacity of 118 mA·h·g^(−1) at 5 C),cyclic ability(94.3%capacity retention after 100 cycles at 0.2 C)and discharge midpoint voltage decay(0.11 V after 100 cycles).Systematic investigation of structural evolution and electrochemical kinetics elucidate that the synergic effect of robust oxygen framework and layered/spinel heterostructure is the key to its performance *** synergy helps to stabilize the layered structure by curbing the structural transformation and oxygen escaping during the electrochemical *** work paved the way for the simple and efficient preparation of highly stable LLO cathode materials.

Objective Assessment in Continual Medical Education (CME) Medical Objective Assessment in System Control

引用

Journal of Integrative Medicine（双语） 2018年第2期7卷 7-11页

作者： yuriy V. Voronenko Ozar P. Mintser dmytro D. Ivanov Larysa yu. Babintseva Shupyk National Medical Academy of Postgraduate Education Kiev Ukraine

Existing examinations in postgraduate education and continuing medical education (CME) are not perfect. Modern assessment does not reflect disadvantages of older responders, for whom more time for reply is needed. Specialists with wide clinical experience may choose more than one correct answer in alternative questions. Reduced ability to remember in older people restricts examination without additional sources of information. We offer an individualised system for testing doctors. It provides personalised choice of examination questions using multiple choice questions with weight characteristics and absence of distractors, interactive cooperation in case of negative answers and the final decision of an expert in relation to the person tested. A special algorithm is proposed for typical questions that combines the advantages of known approaches to testing. The questioning system is complex for the creators of tests, but is more convenient and objective than existing ones for medical doctors.

Dear Editor,Asian rice(Oryza sativa)is the staple food for half the world and is a model crop that has been extensively *** contributes20%of calories to the human diet(Stein et al.,2018).With the increase in global population and rapid changes in climate,rice breeders need to develop new and sustainable cultivars with higher yields,healthier grains,and reduced environmental footprints(Wing et al.,2018).Since the first gold-standard reference genome of rice variety Nipponbare was published(International Rice Genome Sequencing Project,2005),an increasing number of rice accessions have been sequenced,assembled,and annotated with global ***,a single reference genome is obviously insufficient to perform the genetic difference analysis for rice ***,the pan-genome has been proposed as a solution,which allows the discovery of more presence-absence variants compared with single-reference genome-based studies(Zhao et al.,2018).Over the past years,several databases,such as RAP-db(https://***),RGAP(http://***),and Gramene(https://***),have long-term served rice genomic research by providing information based on one or a series of individual reference *** integrate and utilize the genomic information of multiple accessions,we performed comparative analyses and established the user-friendly Rice Gene Index(RGI;https://***)*** is the first gene-based pan-genome database for rice.

The aim of the investigations was to evaluate benefits of the directed transport system - a nanocomposite, based on cisplatin and magnetite combined with local action of constant magnetic field on the tumor, in experiments in vivo in animals with transplantable Guerin carcinoma. Animals were divided into 5 groups according to the type of agent. We showed that nanocomposite in combination with static magnetic field exercises more prominent anti-tumor activity than cisplatin alone. It should be noted that regardless of the therapeutic agent, in Guerin carcinoma we observed
