Authors: Rezaul Islam Abu Bakar Md. Ismail, , T. Yoshinobu and Hiroshi Iwasaki Koji Furuich, 
Published: October 2018

In this article LaF3 films in LaF3/Si structure have been investigated for the measurement of fluoride ions in aqueous solution with higher accuracy using light-addressable potentiometric sensing technique. LaF3 films were directly grown on Si by vacuum evaporation. The effects of LaF3-thickness and annealing on the fluoride-sensitivity of the LaF3/Si structures have been studied. Accordingly four different LaF3/Si structures with various thickness of LaF3 (5/50/150nm) layer were fabricated. The structures are annealed at 400ºC for 10 minutes. The un-annealed LaF3/Si structures show very poor fluoride sensitivity. As predicted in the theoretical study structures with thinner LaF3 offer better steepness of the photocurrent characteristics that indicates better accuracy in fluoride concentration measurement. Among the annealed structures, the one prepared with 150nm LaF3 layer shows the best fluoride sensitivity of ≈ 54.5mV/pF in the range of pF1-pF4. Experimental results show a good promise for LaF3/Si structure as a light-addressable potentiometric sensor that can be used for the sensing and imaging the distribution of fluoride ion in aqueous medium with higher accuracy.

Published: October 2018

Este artigo identifica as representações sociais do ser professor construídas por docentes iniciantes de instituições particulares situadas em Recife-PE. O aporte teórico utilizado foi a Teoria das Representações Sociais. Representações sociais são saberes comuns que explicam a realidade e orientam as práticas das pessoas. Trata-se de um estudo de campo que utilizou como instrumento de coleta um questionário, respondido por 20 professoras com até cinco anos de carreira. Os resultados revelam uma representação social do ser professor pautada na possibilidade de formação dos sujeitos. Essas representações sociais são marcadas pelos sentimentos de desvalorização e falta de reconhecimento social da docência. Indicamos a necessidade de se pensar alternativas que melhor subsidiem o trabalho do docente iniciante na profissão.
Counterfactual Objectives of University Education
Authors: Boychenko Natalia 
Published: October 2018

Subject of counterfactuality is essential for ethics and philosophy of education, but despite this fact, still has not found a proper philosophical reflection in domestic science - rather philosophical texts meet philologists, in linguistics counterfactuality associated primarily with Plusquamperfekt, long-past time that also used increasingly to describe unreality of the situation and actions in the present and future time. Unreality of moral standards is relative – they are unreal only to the extent that they can not be implemented without any special effort – very this effort gives them the power and reality even more than ones having “realistic”, positivist standards. This temporal aspect recedes into the background, and to the foreground opposition steps – of traditionalism and modernity desire to change, to improve the world, ourselves, the others. With Plusquamperfekt one can identify different models as models of counterfactual subjective distancing from the flow of events through distancing from: inadequate (partially adequate) senses; inadequate (excessive, reduced or even false) emotional perception; inadequate action results intentions; values discrepancy of the object of perception. Values are always opposed to the counter-value or irrelevant value. Then and there appears actually a philosophical interest to the concept of counterfactuality that can be called a priori selected context. Thus, taking a counterfactual position, we choose a semantic context of our behavior – sensual, emotional, instrumentally rational, value, etc – and give it absolute value relatively to all other possible contexts – within our strategy of certain behavior. Not omly academic values should be considered after the model of counterfactuality –also other values of university education should be. And the same academic values should be deprived of a significant part of their idealization – a value that acquire a real education is regulatory, not absolute. Academic values become variability in the structure of value orientations of different university communities. If the version of each academic values considered as self-sufficient in its counterfactuality subsystem of values, then one gets pluralistic academic values picture in which different versions of their interpretation partially complementary, but may partially be contradict one another. And counterfactual academic values may be supplemented by other counterfactual university values, such as institutional. Counterfactuality may have different directions and different levels of modalities – both for different communities within the university and for different universities.

Comparative analysis of the results of anatomic restoration of capsuloligamentous system in chronic lateral ankle instability using low invasive arthroscopic techniques was performed.Patients and methods.Forty seven patients (17 - 60 years old) with chronic lateral ankle instability were operated on. In 20 patients a standard “ArthroBrostrum” technique with a use of 2-3 biocomposite fixatives and in 27 patients - the modified arthroscopic intervention with use of 1 titanium anchor was performed. Treatment efficacy was evaluated by AOFAS score.Results. One year after surgery treatment results were followed up in 39 patients: excellent results were achieved in 7 (36.84%), good - in 7 (36.84%), satisfactory - in 3 (15.79%) and poor - in 2 patients after standard technique and in 8 (40.00%), 7 (35.00%), 4 (20.00%) and 1 (5.00%) after modified method, respectively.Conclusion.Thus modified arthroscopic technique is in no way inferior to a standard “ArthroBrostrum” intervention having certain advantages (use of 1 versus 3 fixatives, possibility of intraoperative X-ray control, and shortening of the operation duration). So it could be recommended for the treatment of patients with lateral ankle instability.

Purpose. Improvement of surgical treatment results in patients with benign bone and joint tumors and tumor-like diseases.Materials and methods.Evaluation of the efficacy of plastic collagen containing material for bone defect plasty was performed in 58 Chinchilla rabbits (3-4 kg). In animals from study group the bone defect was filled with collost. Histological examination of the samples was performed in 14, 30, 60 and 90 days after operation. During the period from 2007 to 2015 ninety eight patients, aged 14-75 years, with benign bone and joint tumors and tumor-like diseases were operated on. In all cases postresection defect (1-50 см_) plasty was performed by the proposed combined method that included the use of frozen allograft and collost. During subsequent follow up the potentiality of pathologic process relapse was determined as well as the dynamics of bone structure restoration, extremity function and bone anatomic shape were assessed.Results.Pathomorphologic picture of experimental samples showed that collast accelerated the bone regenerate maturity in the place of a defect. In 1 year after surgery 74 patients (75%) showed good results - in 8 (11.2%), satisfactory - in 62 (84.1%), poor - in 3 (4.7%) cases and in 3 years after operation (57 patients) - 28 (49.1%), 28 (49.1%) and 1 (1.7%) case respectively. Examination of 56 patients (57.1%) in 5 years after intervention revealed good results in 48 (85.4%) and poor - in 8 (14.6%) cases.Conclusion.Study results allow recommending the proposed method of plasty using the allograft and collost for the substitution of vast postresection defects in patients with benign bone and joint tumors and tumor-like diseases.

Published: October 2018

Purpose of study. Evaluation of the pain sources and comparative analysis of chronic pain syndrome peculiarities in patients with various types of disc herniation before and after surgical intervention at lumbosacral level.Patients and methods. The study included 80 patients (20-60 years old) with discogenic pathology at lumbosacral level. The type and size of herniation was assessed by MSU classification. Every patient went through a complex evaluation of low back pain sources, pain syndrome characteristics and personality before and on day 10 after surgery.Results.The most common cause of pain was a musculoskeletal syndrome that was more pronounces in the older (41-60 years) group. Neither correlation between the degree of degenerative dystrophic changes and type and size of discogenic pathology, nor the relation between the disc herniation size and type and neurologic symptoms development was detected. The relation between the intensity and other characteristics of pain syndrome and type of disc herniation was not detected too. Analysis of pain syndrome characteristics and mechanisms in complex with the assessment of pain sources revealed the group of patients with high pain and emotionally affected indices before and after surgical intervention and mild vertebrogenic and other pain sources. That group made up 13% of the total number of patients; the majority of them (75%) were females (mean age 37.8±5.0 years) and in 50% of cases the herniation size and localization corresponded to type 2A. Taking into consideration a high degree of disability and other pain indices in postoperative period we do not recommend surgical intervention in this group of patients.Conclusion.Management of patients with lumbosacral intervertebral disc herniation requires the evaluation of all pain sources and pain syndrome aspects.

Purpose:to evaluate the efficacy of the conservative treatment of patients with subacromial impingement syndrome (SIS) and supraspinatus muscle tendon (SMT) pathology using optimized clinical and beam algorithm.Patients and methods.Complex evaluation of the conservative treatment efficacy (physiotherapeutic treatment (PHT), exercise therapy (ET), shockwave therapy (SWT)) was performed in 128 patients 67 (52.3%) men, 61 (47.7%) women with SIS. Mean age of patients was 59±8 years (24 – 82 yrs), follow up period – 9.6 ±5.6 months (maximum 18 mos). All patients underwent optimized complex clinical and beam examination. Treatment efficacy was evaluated in dynamics at terms 3, 6 and 9 months. Dynamics of pain syndrome and structural changes in STM regress was assessed depending on the type of treatment.Results.In 3 months positive effect of conservative treatment was noted in 67 (65%), in 6 months – in 78 (77%) and in 9 months – in 84 (82%) patients. High correlation of data obtained using the elaborated pain scale for a shoulder with the visual analogue scale data at treatment monitoring (r=0,89) as well as with the monitoring US data (r=0,94) was determined. The combination of SWT+ET+PHT or SWT+PHT showed good therapeutic effect in 3 months after treatment and by 6th month excellent result was recorded in 85% of cases. Due to the long rehabilitation period in operated patients in 3 and 6 months after intervention only the satisfactory result with mean point 3.02±0.12 and 3.52±0.14 respectively was achieved.Conclusion.In patients with SIS and SMT pathology the most effective is a combined conservative treatment with SWT+ET+PHT or SWT+PHT. However a conservative treatment efficacy is significantly influenced by the SIS stage, anatomical structure of acromeonon as well as the type of SMT structural changes.

During the researches, carried out in the article, sodium chloride recommended itself as the best fire-extinguishing substance. In order to give it the properties of a fire extinguishing powder, two more components were added to it, namely ground slag and aerosil. These components were chosen according to their physical and chemical properties. As evidenced by the corresponding quenching parameters, the optimal composition of the fire extinguishing powder was established on the basis of performed experiments and obtained dependences. The properties of the fire extinguishing powder were improved by adding ground slag and aerosil. These additives increase the heat resistance, insulating and anti-caking ability, fluidity and fire-extinguishing efficiency of the powder. The best results were obtained after using the extinguishing powder of such composition: sodium chloride - 73.5%, ground slag - 25%, aerosil - 1.5%. Experimental-empirical dependence for determination the extinguishing intensity according to the extinguishing parameters and the fire-extinguishing composition was developed.

Abstract
We present an analysis using the MOSFIRE Deep Evolution Field (MOSDEF) survey on the nature of “MIR-excess” galaxies, which have star formation rates (SFRs) inferred from mid-infrared (MIR) data that are substantially elevated relative to those estimated from dust-corrected UV data. We use a sample of ∼200 galaxies and active galactic nuclei (AGNs) at 1.40 < z < 2.61 with 24 μm detections (rest-frame 8 μm) from MIPS/Spitzer. We find that the identification of MIR-excess galaxies strongly depends on the methodologies used to estimate IR luminosity (

) and to correct the UV light for dust attenuation. We find that extrapolations of the SFR from the observed 24 μm flux, using luminosity-dependent templates based on local galaxies, substantially overestimate

in z ∼ 2 galaxies. By including Herschel observations and using a stellar-mass-dependent, luminosity-independent

, we obtain more reliable estimates of the SFR and a lower fraction of MIR-excess galaxies. Once stellar-mass selection biases are taken into account, we identify ∼24% of our galaxies as MIR excess. However,

is not elevated in MIR-excess galaxies compared to MIR-normal galaxies, indicating that the intrinsic fraction of MIR excess may be lower. Using X-ray-, IR-, and optically selected AGNs in MOSDEF, we do not find a higher prevalence for AGNs in MIR-excess galaxies relative to MIR-normal galaxies. A stacking analysis of X-ray-undetected galaxies does not reveal a harder spectrum in MIR-excess galaxies relative to MIR-normal galaxies. Our analysis indicates that AGN activity does not contribute substantially to the MIR excess and instead implies that it is likely due to the enhanced polycyclic aromatic hydrocarbon emission.

Published: October 2018

Introduction: The quality of drinking water has an important role in human health. This study was aimed to detect Escherichia. coli, Salmonella sp. and Vibrio cholerae from bottled drinking waters produced in Iran.
Methodology: A total of 240 samples of bottled water of different brands were collected for testing between March 2015 to December 2015 in Shahrekord-Iran. Samples were examined by polymerase chain reaction (PCR) combined with culture methods for the detection of E. coli, Salmonella sp., and V. cholerae.
Results: The results of PCR revealed that the uidA gene from E. coli, IpaB gene from Salmonella sp, and epsM gene from V. cholerae were detected in 6 (2.5%), 1 (0.4 %), 0 (0%) of the samples, respectively. But in culture methods, only E. coli 5 (2.1%) were isolated from the samples. The contamination with E. coli was significantly higher (P < 0.05) in water produced during the hot seasons than the cold seasons.
Conclusions: This study confirmed the presence of Escherichia coli as the main microorganism in bottle drinking water in Iran. Also, our study showed that PCR can be used as a screening method for monitoring the enteric pathogens in drinking water.

Introduction: Viral genotype and variation in host genes involved in the immune response may predict the treatment response in patients infected with HCV. The present study was designed to determine the distribution pattern of HCV and host genotypes in Chronic Hepatitis C (CHC) patients and their association with virological response and other risk factors.
Methodology: Two hundred and fifty (n = 250) HCV positive patients were included in the study. HCV and Interleukin 28B (IL28B) genotyping was carried out by PCR-RFLP.
Results: Viral genotype 3 was the predominant genotype seen in 187 (74.8%) patients. Wild genotype predominated in rs12979860, rs12980275 and rs8099917 SNP of IL28B gene. A significant difference was found in end stage virological response (EVR) between HCV genotype 1 infected patients with wild and variant genotype for rs12980275 and rs8099917 SNPs respectively (P < 0.05). On multivariate analysis all the SNPs were found to be associated with each other (P < 0.05) with rs12980275 SNP associated with history of Jaundice (P < 0.05). Viral genotype 3 was significantly associated with age (< 50 years) and rapid virological response (RVR) while as viral genotype 1 was significantly associated with history of surgery on multivariate analysis (P < 0.05).
Conclusions: The viral genotype and IL28B polymorphisms are important factors to personalize antiviral therapy of patients with CHC.
