Natural disasters in the Russian Federation
Authors: Kuzmin S. V.
Published: April 2019

In recent decades, hazardous natural processes, natural disasters and catastrophes in theRussian Federationhave noticeably intensified. This is due both to global climate and the natural environment change, and to the rapid growth of human impact on landscapes and ecosystems. The current situation has determined a significant increase in the number and scale of emergency situations of natural and natural-technogenic character, material and moral damage among the population and economic infrastructure. Hazardous natural processes have become the regulator of the development of society through a direct impact on the state of the economy and social sphere in theRussia, which forces management structures at all levels — from federal to municipal — to switch to the principles of admissible risk in administrative and territorial mechanisms. And the implementation of these mechanisms is impossible without strict accounting and control of hazardous natural processes, their functioning, dynamics and evolution. The review given in the article shows the main directions of such activities in relation to the subjects of theRussian Federationand large natural complexes.

It is showed that the key factor at the solution of problems of an estimation and control of risks for social, natural and technogenic spheres is use of the concept of the analysis and monitoring of the risks, founded on determination of base parameters of a current and probable dangerous state of analyzed socially-natural-technogenic system. Importance of safety maintenance and protect-ability tasks of basic practices and appearances in such system is interlinked to spreading of scientific possibilities and actual methods of decrease of risks, and also with an in-depth analysis of a spectrum of dangers, defiances, threats, crises, emergency situations, disasters at increment of losses from them to a person, a society, the state, an environment and an ability to live of infrastructure. The universal quantitative measure of probabilities of initiation and implementation of the indicated unfavorable events and processes in a combination to accompanying them losses are risks of the stacked state and prospects of evolution of considered system. Builted on results of corresponding comprehensive analysis the theory, algorithms and program complexes for determination, maintenances and raises of protectability of objects in social, natural and technogenic spheres taking into account the bundled to them risks are scientific baseline for a justification of decrease of their interlinked values to acceptable level. Making and service of objects and an infrastructure of ability to live for a person, a society and the state on the basis of a meeting the requirements to acceptable levels of risks and to guard of objects from accidents and disasters present an essence of transition to new level of the state strategic planning certified to the strategy of national safety of Russia.
Predicting response rates of all and recruited respondents: A first attempt
Authors: Schmid Basil , Axhausen Kay W.
Published: April 2019

This paper reports on the link between a well-defined measure of response burden and response rates among all (uncommitted) and pre-recruited respondents. We show within the limits of our sample of 68 survey waves (including pre-tests; resulting from 35 studies) that the response burden impact is mediated by the level of the commitment of the respondents and the presence of a monetary incentive. This is the first time that a research group provides a response rate forecasting model for its own work and for others to adopt, test and adapt.

Contemporary Approach to Specialization in Mazovi
Authors: Kozubek Elżbieta , Strzelecki Zbigniew
Published: April 2019

Supporting smart specialization, taking into account regional potential, makes sense in the case of probable, significant increase of a competitive advantage in the region. This should result in economic growth. In turn, countering dispersion of the EU support by indicating smart specialization of a given region, constituting one of the policy objectives for regions, does not guarantee development of these specializations, and therefore, economic growth. One must remember that development of given specializations is a result of the local-level processes, which determine the market and at the same time being the main stimulant for their formulation. The strategic objective should be the introduction of such a system which will generate innovations, taking into account the advanced technologies and their diffusion into less developed areas. Flexibility should be an important aspect, understood as the capacity of specific areas to modify the use of their own potential. It is important to shape and promote pro-innovative and proentrepreneurial stances. Designating smart specialization and supporting it with the EU funds cannot be a goal in itself, but a carefully considered and prudent financial policy.
Pomoc publiczna na szkolenia pracowników a konkurencyjność gospodarki Unii Europejskiej
Authors: Podsiadło Piotr
Published: April 2019

The paper discusses guidelines for implementation of art. 107-109 of the Treaty on the Functioning of the European Union, from the point of view of state aid for training. Training usually generates positive externalities for society as a whole, since it increases the pool of skilled workers from which other firms may draw, improves the competitiveness of the EU industry and plays an important role in the EU employment strategy. Statistical analysis was carried out on state aid granted by the EU Member States in the period 2001-2014 - from the perspective of its impact on competitiveness of these countries. This should lead to verification of thesis that the amount of state aid granted by the EU Member States for training, should positively correlate with the size of the GDP per capita of these countries

More generally, it places the Polish coal policy within the wider set of balance-of-payment supporting measures.
Stress at Work: Its Impact on Sustainable Growth
Authors: Pawełczyk-Cnudde Beata
Published: April 2019

This paper aims to show the importance of stress at work for the economy. Stress, which until recently was considered mainly in psychological or social terms, has a direct impact on human capital and labour, which are the basic factors of economic growth (as well as natural resources, technology, physical and financial capitals). The quality and quantity of human capital directly affects the growth of the economy. An increase in investment in human capital can improve the quality of the labour force, hence its productivity. On the other hand, factors that limit economic growth include: poor health and low level of education. People who do not have access to healthcare or education have lower levels of productivity. The economy, therefore, does not fulfil its potential productivity or growth. Stress negatively contributes to changes of these factors. It has become one of the main causes of disability and inability to work in recent years.The first part describes the overall situation in which stress has become an issue for companies and the economy. In the second part I present the different research findings that demonstrate how the meaning and importance of work, and workplace conditions, have evolved. I refer, as well, to quantitative findings proving that companies should invest in preventing stress at work as excessive stress affects performance and productivity. The third part briefly portrays the example of Belgium, where the problem of stress and its economic consequences have been quite thoroughly investigated. The costs of excessive stress were regarded as undue, and as a result, Belgium adopted a law protecting employees against stress and burnout at work. Under this law, employers are obliged to introduce specific internal rules and preventative measures. Based on the Belgian experience, I provide several arguments demonstrating that improving the workplace by mitigating stress levels is beneficial not only for a company itself but for the economy in general. It impacts positively human capital, employability, leads to improved productivity, and in the end, contributes to sustainable economic growth. At the end of the paper, in an annex, I present a case illustrating the problem of excessive stress at work. It is an example of the great pressure and stress imposed on employees during the time of the ongoing business changes in one of the financial companies based in Brussels. The purpose of this article, however, is not to exhaust the topic of the impact of stress on economy, but rather to induce discussion on the magnitude and importance of this problem.
Partnerstwo lokalne w ekonomii społecznej jako nowy paradygmat budowania spójności społecznej ​
Authors: Łojko Majka
Published: April 2019

The social economy has been trying to recognize its partnering role by the public and business sectors over recent years. The results are visible in the increasing use of its instruments in policy implemented by both the government and the regional authorities. The essence of local partnership is one of the key issues inherent in the new paradigm of building social cohesion and is a tool for a new economic and social order. The task of local partnership, understood as a kind of relationship between public entities, business and non-governmental organizations based on the principles of dialogue, reciprocity and equivalence, is to combine knowledge, experience and initiatives of various people and institutions in solving social problems.
Zróżnicowanie przestrzenne dochodów własnych budżetów gmin w Polsce w latach 2007–2015​
Authors: Jarosiński Krzysztof
Published: April 2019

The experience of systemic transformation in Poland and the progressing socio-economic development prove that the importance of organizational units classified conventionally as a part of the public sector has increased significantly. It turned out that during rapid economic and social changes, the development of technical and social infrastructure became one of the drivers of development. In the conditions of the market economy in Poland, two important areas related to the functioning of the public sector have come to the fore: quantification of objectives and tasks necessary for the proper functioning of the state and society and ensuring efficient sources of financing these tasks. In this paper the aim of the research was to analyse and assess the financial situation of municipal territorial self-government units in Poland in 2007–2015. The research results clearly indicate the existence of differences in the level of budget revenues between differentiated territorial self-government units in the years 2007–2015. In that time the budget revenues of communes increased and significant positive changes in the budgetary situation of municipal local government units took place, in almost all regions these incomes doubled. This increase was accompanied by persistence of disproportions between less developed regions and regions that were economically and socially developing faster. In the discussed period, we had to deal with the improvement of the income situation of the budgets of local government units, with the simultaneous increase in the differences in the level of income with all the consequences associated with this for future development.
The model of a dynamic university library based on the leading query services
Authors: Baryshev Ruslan , Babina Olga , Manushkina Margarita , Tsvetochkina Irina
Published: April 2019

The university libraries are analyzed as an integrated system of elements with various characteristics. Within any system, any structural changes will inevitably impact its every component. The authors describe the mechanism for leading query and corresponding services. They also define the term “dynamic university library” which is the traditional or networked user information services with any media based on the leading query services. The dynamic library services are classified by the library specialization (library, research and academic services) and by information delivery method (traditional, online traditional and the leading query services). The core collection structure comprises three equally-weighted elements: the basic, intermediary, and intellectual one. The scheme of useable library operation is revealed. Along with sources ordered, the libraries can offer a series of additional services: reviews, author’s bibliography, citation data, subject bibliographies, etc. Based on the suggested classification, the core structure and operation scheme, the model of a dynamic university library is designed.

Authors: Filatova D U , Veraksa A N , Berestin D K , Streltsova T V
Published: April 2019

The paper presents the study results of thermometry indices in boys and girls aged 20 - 28 years old living in the North more than 15 years and having different background of conditioning. Average age of surveyed was 22,8 years. The thermometer readings were register before and after local cooling. Traditional statistical ratios were calculated. They demonstrated Eskov-Zinchenko effect for tremor and quasiattractors areas, thermogramm pairwise comparison matrixes of three groups of surveyed before and after cooling from the perspective of self-organization. Quasiattractors showed the most diversity in comparison with stochastics and the thermogramm pairwise comparison matrixes in trained persons scarcely changed before and after cooling which was high adaptation parameter to cooling. This points significant differences in organism reactions in all the surveyed groups (untrained, poorly trained and strongly trained). Worked out methods to assess changes in the characteristics of quasiattractors can be used individually (for each test person) to assess your personal training level (in the repetition of measurements), and for group studies.

Authors: Gubareva L Ivanovna , Soloviev A G , Bicheva G V , Ermolova L S
Published: April 2019

Purpose of investigation: to reveal the combined influence of hypo (Zn, Fe) and hyper (Cd, Pb) microelementosis on functional status of the cardiovascular, endocrine systems and anxiety level of adolescents (13 years of age) living in a chemically contaminated area in Stavropol region. The level of microelements (Cd, Pb, Fe, Zn, Cu) in hair and nails was determined by atomic absorption spectrophotometry method, cortisol in saliva - by ELISA method. The state of the cardiovascular system and its regulatory mechanisms was determined by indicators of variational pulsometry. To assess anxiety level of adolescents test method "Anxiety scale" was used. The analysis of microelement composition of hair and nails in adolescents, living in conditions of chemical environmental pollution with Cd and Pb subliminal doses, revealed the presence of hypo- (Zn, Fe) and hyper- (Cd, Pb) microelementosis. At the same time, increased levels of cortisol in saliva more evident in boys, increased heart rate and mode amplitude, peassure of the central mechanisms of the heart function regulation have been discovered. Change of anxiety level was stated. It has been proved that the determination of the microelement composition of hair and nails can serve as a marker of environmental contamination and complex negative changes, including the imbalance of microelements in hair and nails, functional changes in leading adaptive systems - the hypothalamic-pituitary-adrenocortical axis, cardio-vascular, changes of anxiety level can be used as a marker of dysaptation and predictor of psychosomatic problems.

Published: April 2019

Chronic occlusive disease of lower limb arteries is a widespread disease of the blood vessels, where due to arteriostenosis there appears arterial misperfusion in the limb. According to the data, nowadays from 2 to 15 % of the adult population suffer from this disease. The literature review shows the relevance of studying the problem of peripheral arteries occlusive diseases (PAD) in the extreme environmental conditions of the Northern latitudes. The analysis conducted by scientists of Surgut city showed that the most important etiological factors resulting in PAD are atherosclerosis (54.5 %) and occlusive tromboangitis (45.3%). Occlusive diseases of the vascular system have multisegmental nature and appear at a young age and often have malignancy flow. The development of atherosclerotic process in its classic version starts at the age of 40-50 years, more often with sectoral lesions in the iliac segment. Occlusive process, once appeared, has no tendency to reverse development, and the outcome of this process (40 % of patients with PAD) is a disability or limb amputation. The study results showed that in young people living in KHMAO-Yugra, endothelial function was characterized by more evident disorders compared to normal rates; the severity of dysfunction was higher than in healthy individuals with risk factors for cardiovascular diseases. The biological age of the subjects met people over 40, and in men, the processes of biological aging was characterized by greater severity.

Teacher competency is as knowledge, skills, and abilities mastered by someone who has become a part of him so that he can do cognitive, affective, and psychomotor behavior as well as possible. But in reality, there are still many weaknesses encountered especially in the implementation of the learning process carried out by teachers at the 017 Pasir Emas Public Elementary School. For this reason, we need a strategy that can help teachers achieve their competencies. In this case the researcher tries to intensify the implementation of academic supervision in an effort to minimize weaknesses in carrying out the learning process. The aim is to improve the process of implementing learning carried out by teachers in the classroom. The results showed, where the average value of teachers in the learning process cycle I was 72.85 with sufficient categories. After the second cycle, the value of teacher competence in the process of learning has increased to 88.00 with a very good category. This proves that, through academic supervision, it can improve teacher competence in the implementation of the learning process in 017 Pasir Emas Public Elementary School.
Funcionamiento Familiar en Amas de Casa Mexicanas cuando la Pareja Emigra
Authors: Robles Estrada Erika , Oudhof van Barneveld Hans , Mercado Maya Aida
Published: April 2019

Entre otros países, México ha sido a través de la historia uno de los principales países con la mayor tasa de emigrantes económicos hacia Estados Unidos de América. En la década de los setenta había 879 mil personas (Zúñiga, 2004; INEGI, 2015). Sin embargo, en 2003 la cifra se elevó hasta 26.7 millones contabilizando también a sus descendientes (Zúñiga, 2004; INEGI, 2015). Tradicionalmente, es el padre de familia quien emigra dejando a la familia en su país natal. Por tanto, es preciso cuestionarse lo siguiente: ¿Cómo perciben las amas de casa el funcionamiento familiar cuando la pareja emigra a Estados Unidos de América? En este estudio, el funcionamiento familiar se conceptualizó en términos de resolución de problemas, comunicación, roles, involucramiento afectivo, respuestas afectivas y control de conducta. Seleccionamos la aproximación del enfoque sistémico para abordar el concepto de funcionamiento familiar. Este es un estudio cualitativo con diseño fenomenológico psicológico del funcionamiento familiar. La muestra consistió en 10 mujeres del municipio de Tonatico, Estado de México, cuyas parejas eran migrantes económicos en EE. UU. Usamos el grupo focal y la narrativa como técnicas cualitativas para recolectar los datos. Descubrimos 14 temas del funcionamiento familiar. De estos temas, 8 estaban relacionados con aspectos instrumentales y 6 con aspectos afectivos. Con la partida de la pareja, las participantes percibieron el funcionamiento familiar como un proceso de ajuste continuo, con implicaciones afectivas e instrumentales. Concluimos que en el contexto mexicano, la migración del padre de familia impacta severamente en el funcionamiento de la familia.

Se propuso conocer la vulnerabilidad sanitaria y necesidades de salud de personas inmigrantes en Chile, a través de un estudio cualitativo exploratorio. Los hallazgos indican que su vulnerabilidad estaría dada por su condición irregular, trabajo precario y bajos ingresos, cuando lo tienen. Las afecciones de salud son morbilidad común, de salud mental y reproductiva. La aculturación y actitud positiva hacia el autocuidado serían factores protectores. Importante barrera de acceso es la situación ilegal de algunos inmigrantes; y el desconocimiento del sistema sanitario chileno. Se sugiere socializar políticas sanitarias para migrantes y expandir estrategias dirigidas para su atención de salud.
An Algorithm for Producing Fuzzy Negations via Conical Sections
Authors: Souliotis Georgios , Papadopoulos Basil
Published: April 2019

In this paper we introduced a new class of strong negations, which were generated via conical sections. This paper focuses on the fact that simple mathematical and computational processes generate new strong fuzzy negations, through purely geometrical concepts such as the ellipse and the hyperbola. Well-known negations like the classical negation, Sugeno negation, etc., were produced via the suggested conical sections. The strong negations were a structural element in the production of fuzzy implications. Thus, we have a machine for producing fuzzy implications, which can be useful in many areas, as in artificial intelligence, neural networks, etc. Strong Fuzzy Negations refers to the discrepancy between the degree of difficulty of the effort and the significance of its results. Innovative results may, therefore, derive for use in literature in the specific field of mathematics. These data are, moreover, generated in an effortless, concise, as well as self-evident manner.

Authors: Di Pasquale Jorgelina , Nannoni Eleonora , Sardi Luca , Rubini Giulia , Salvatore Renato , Bartoli Luca , Adinolfi Felice , Martelli Giovanna
Published: April 2019

Immunocastration of pigs represents an alternative method to surgical castration, being more respectful of animal welfare. However, this new technology may not be accepted by consumers due to their perception of possible risks tied to the use of the product, thus representing a concern for the production sector. The study aimed at verifying the attitude of Italian consumers towards immunocastration and to assess whether their perception can be affected by science-based information on advantages and disadvantages of immunocastration. A total of 969 consumers (divided in three groups representative of the Italian population) were contacted and asked to complete an online questionnaire. Only technical (neutral) information on immunocastration was provided to the first group; the second and the third group received information on the advantages (+) and disadvantages (-) of the technique, shown in reverse order (+/- and -/+, respectively). The level of information did not affect consumers’ perception of immunocastration. Overall, immunocastration is perceived in a predominantly positive manner (54.5%), with a relatively low level of risk perception (34.2%), and a good willingness to pay more for meat deriving from immunocastrated pigs (+18.7%).
NO-CH4-SCR Over Core-Shell MnH-Zeolite Composites
Authors: Li Yixiao , Wang Quanhua , Wang Ding , Yan Xiaoliang
Published: April 2019

Selective catalytic reduction of NO with methane (NO-CH4-SCR) in the presence of excess oxygen was investigated over the synthesized MnH-ZZs-n zeolite composite catalysts with FAU (as core) and BEA (as shell) topologies. XRD, SEM, and NH3-TPD technologies were employed to characterize the catalysts. It is found that the topological structure of the zeolite affected the catalytic properties and H2O/SO2 tolerances considerably. MnH-ZZs-n catalysts exhibited much higher NO-CH4-SCR activity than the physical mixture catalysts with comparable relative mass content of Y and Beta zeolites, particularly the ratio of Y and Beta at the range of 0.2–0.5 than the MnH-Beta catalysts with single topology. NH3-TPD results showed that one new type of strong acidic sites formed in H-ZZs-n and remained in MnH-ZZs-n resulted from the interaction between the Lewis and Brönsted acid sites under a particular environment. The special zeolite-zeolite structure with ion-exchanged Mn ions in the core-shell zeolite composite catalysts contributed to the novel NO-CH4-SCR properties.
Continuous-Service M/M/1 Queuing Systems
Authors: Chew Song
Published: April 2019

In this paper, we look into a novel notion of the standard M/M/1 queueing system. In our study, we assume that there is a single server and that there are two types of customers: real and imaginary customers. Real customers are regular customers arriving into our queueing system in accordance with a Poisson process. There exist infinitely many imaginary customers residing in the system. Real customers have service priority over imaginary customers. Thus, the server always serves real (regular) customers one by one if there are real customers present in the system. After serving all real customers, the server immediately serves, one at a time, imaginary customers residing in the system. A newly arriving real customer presumably does not preempt the service of an imaginary customer and hence must wait in the queue for their service. The server immediately serves a waiting real customer upon service completion of the imaginary customer currently under service. All service times are identically, independently, and exponentially distributed. Since our systems are characterized by continuous service by the server, we dub our systems continuous-service M/M/1 queueing systems. We conduct the steady-state analysis and determine common performance measures of our systems. In addition, we carry out simulation experiments to verify our results. We compare our results to that of the standard M/M/1 queueing system, and draw interesting conclusions.

The Arabian Peninsula is one of the world’s largest sources of mineral dust that includes several major population hotspots. However, until now, few studies have performed a comprehensive quantification of the long-term variability of aerosol species in this region. In this study, the speciation, variability, and distribution of aerosol optical depth over the Arabian Peninsula during 2005–2015 is analyzed by using the modern-era retrospective analysis for research and applications, Version 2 (MERRA-2) model together with satellite retrieved data and AERONET observations and focusing on nine large cities in the region (Dammam, Doha, Dubai, Jeddah, Kuwait, Manama, Muscat, Riyadh, and Sanaa). Over the past decade, the mean annual aerosol optical thickness (AOT) values were in the range of 0.3–0.5, which is attributed to both mineral dust (60–70%) and anthropogenic activities (20–30%). An increase in AOT values between 2005 and 2009 is attributed to increased dust generation from the Sahel region in Northern Africa, and the Fertile Crescent (Syria, Iraq, Jordan) due to an extended dry period. Reductions in local urban emissions are still considered to be efficient measures to improve air quality in these population centers despite the significant contribution of desert dust in the total particulate matter levels in the region.

The question of whether anesthetic, analgesic or other perioperative intervention during cancer resection surgery might influence long-term oncologic outcomes has generated much attention over the past 13 years. A wealth of experimental and observational clinical data have been published, but the results of prospective, randomized clinical trials are awaited. The European Union supports a pan-European network of researchers, clinicians and industry partners engaged in this question (COST Action 15204: Euro-Periscope). In this narrative review, members of the Euro-Periscope network briefly summarize the current state of evidence pertaining to the potential effects of the most commonly deployed anesthetic and analgesic techniques and other non-surgical interventions during cancer resection surgery on tumor recurrence or metastasis.

Helicobacter pylori (H. pylori) has been shown to be a causal factor of gastric cancer in cohort studies and animal models. Meta-analysis of case-control studies nested within prospective cohorts showed that H. pylori infection was associated with a 5.9-fold increased risk of non-cardia gastric cancer. Prospective cohort studies showed that gastric cancer developed in 1–4% of H. pylori-infected subjects. Gastric cancer was successfully induced in Mongolian gerbils and insulin-gastrin (INS-GAS) transgenic mice after inoculation of H. pylori. Meta-analysis of randomized control trials also showed that eradication of H. pylori may reduce the risk of gastric cancer. However, there are several concerns regarding the widespread use of antibiotics to prevent gastric cancer, including the emergence of antibiotic resistance and the perturbation of gut microbiota after H. pylori eradication. Recent studies showed that eradication of H. pylori resulted in an increase in the bacterial diversity and restoration of the relative abundance of other bacteria to levels similar to H. pylori non-infected subjects in the gastric microbiota. The administration of antibiotics may also alter the composition of intestinal microbiota. The α-diversity and β-diversity of fecal microbiota are significantly altered immediately after H. pylori eradication but are gradually restored to levels similar to those before therapy. Yet, the rate of recovery varies with regimens. The diversity was restored at week 8 after triple therapy but was not yet fully recovered at 1 year after concomitant and quadruple therapies. Some studies showed that supplementation of probiotics may reduce the dysbiosis during H. pylori eradication therapy. Although some earlier studies showed high levels of macrolide resistance after triple therapy, recent studies showed that the increased antibiotic resistance rate may be restored 2–12 months after eradication therapy. These results collectively provide evidence of the long-term safety of H. pylori eradication. Yet, more prospective cohort studies and randomized trials are warranted to assess the efficacy and long-term safety of H. pylori eradication for gastric cancer prevention.

Background: We aimed to investigate the association between single-nucleotide polymorphisms (SNP) in mismatch repair (MMR) pathway genes and survival in patients with oral squamous cell carcinoma (OSCC) who received adjuvant concurrent chemoradiotherapy (CCRT). Methods: Using the Sequenom iPLEX MassARRAY system, five SNPs in four major MMR genes were genotyped in 319 patients with OSCC who received CCRT treatment. Kaplan–Meier survival curves and Cox proportional hazard regression models were used to assess overall survival (OS) and disease-free survival (DFS) among MMR genotypes. Results: The results of Kaplan–Meier survival analysis revealed that the MutS homolog 2 (MSH2) rs3732183 polymorphism showed a borderline significant association with DFS (log-rank p = 0.089). Participants with the MSH2 rs3732183 GG genotype exhibited a relatively low risk of recurrence (hazard ratio (HR) = 0.45; 95% confidence interval (CI) = 0.22–0.96; p = 0.039). In addition, the MutL homolog 1 (MLH1) rs1800734 GG genotype carriers exhibited higher OS (HR = 0.52, 95% CI = 0.27–1.01; p = 0.054) and DFS (HR = 0.49, 95% CI = 0.26–0.92; p = 0.028) rates. Conclusions: Our results indicated that the GG genotypes of MSH2 rs3732183 and MLH1 rs1800734 are associated with relatively high survival in OSCC patients treated using adjuvant CCRT. These polymorphisms may serve as prognosis predictors in OSCC patients.

Published: April 2019

The pathological diagnosis of lung cancer has largely been based on the morphological features observed microscopically. Recent innovations in molecular and genetic technology enable us to compare conventional histological classifications, protein expression status, and gene abnormalities. The introduction of The Cancer Genome Atlas (TCGA) project along with the widespread use of the next-generation sequencer (NGS) have facilitated access to enormous data regarding the molecular profiles of lung cancer. The World Health Organization classification of lung cancer, which was revised in 2015, is based on this progress in molecular pathology; moreover, immunohistochemistry has come to play a larger role in diagnosis. In this article, we focused on genetic and epigenetic abnormalities in non-small cell carcinoma (adenocarcinoma and squamous cell carcinoma), neuroendocrine tumor (including carcinoids, small cell carcinoma, and large cell neuroendocrine carcinoma), and carcinoma with rare histological subtypes. In addition, we summarize the therapeutic targeted reagents that are currently available and undergoing clinical trials. A good understanding of the morphological and molecular profiles will be necessary in routine practice when the NGS platform is widely used.

Inducible genetically defined mouse models of cancer uniquely facilitate the investigation of early events in cancer progression, however, there are valid concerns about the ability of such models to faithfully recapitulate human disease. We developed an inducible mouse model of progressive lung adenocarcinoma (LuAd) that combines sporadic activation of oncogenic KRasG12D with modest overexpression of c-MYC (KM model). Histological examination revealed a highly reproducible spontaneous transition from low-grade adenocarcinoma to locally invasive adenocarcinoma within 6 weeks of oncogene activation. Laser-capture microdissection coupled with RNA-SEQ (ribonucleic acid sequencing) was employed to determine transcriptional changes associated with tumour progression. Upregulated genes were triaged for relevance to human LuAd using datasets from Oncomine and cBioportal. Selected genes were validated by RNAi screening in human lung cancer cell lines and examined for association with lung cancer patient overall survival using KMplot.com. Depletion of progression-associated genes resulted in pronounced viability and/or cell migration defects in human lung cancer cells. Progression-associated genes moreover exhibited strong associations with overall survival, specifically in human lung adenocarcinoma, but not in squamous cell carcinoma. The KM mouse model faithfully recapitulates key molecular events in human adenocarcinoma of the lung and is a useful tool for mechanistic interrogation of KRAS-driven LuAd progression.

Authors: Abutaleb Ahmed
Published: April 2019

Bimetallic Cu3.8Ni alloy nanoparticles (NPs)-anchored carbon nanofibers (composite NFs) were synthesized using a simple electrospinning machine. XRD, SEM, TEM, and TGA were employed to examine the physiochemical characteristics of these composite NFs. The characterization techniques proved that Cu3.8Ni alloy NPs-anchored carbon NFs were successfully fabricated. Urea oxidation (UO) processes as a source of hydrogen and electrical energy were investigated using the fabricated composite NFs. The corresponding onset potential of UO and the oxidation current density (OCD) were measured via cyclic voltammetry as 380 mV versus Ag/AgCl electrode and 98 mA/cm2, respectively. Kinetic study indicated that the electrochemical oxidation of urea followed the diffusion controlled process and the reaction order is 0.5 with respect to urea concentration. The diffusion coefficient of urea using the introduced electrocatalyst was found to be 6.04 × 10−3 cm2/s. Additionally, the composite NFs showed steady state stability for 900 s using chronoamperometry test.

Published: April 2019

Research from the International Energy Agency about indoor ambiences and nearly zero energy buildings (nZEB) in the past has been centred on different aspects such as the prediction of indoor conditions as a function of the weather using laboratory material properties for simulations and real sampled data for validation. Thus, it is possible to use real data for defining behavioural groups of indoor ambiences as a function of real vapour permeability of internal coverings. However, this method is not suitable for modelling it and predicting its behaviour under weather changes, which is of interest to improve the method of selection and use of building construction materials. In this research, artificial intelligence procedures were employed as the first model of permeable coverings material behaviour to provide a newer understanding of building materials and applications for the generation of new control procedures between the mechanical and electronic point of view of building construction materials.

Fluoropolymer-based coatings are widely used for release applications. However, these hydrophobic surfaces do not reveal a significantly low adhesion. Water repellency incorporated to fluoropolymer coatings might enhance their release performance. In this work, we focused on the surface texturing of a well-known polytetrafluoroethylene (PTFE)-based coating. We explored as texturing routes: sanding, sandblasting and laser ablation. We examined the surface roughness with white light confocal microscopy and the surface morphology with environmental scanning electron microscopy (ESEM). Water-repellent fluoropolymer coatings were reproduced in all cases, although with different degree, parametrized with bounces of water drops (4–5 μL). Laser ablation enabled the lowest adhesion of coatings with 24 ± 2 bounces. This result and the current development of laser patterning for industry assure the incipient use of laser ablation for release coatings.
