Por uma história cultural da música: conflitos sociais e simbólicos no horizonte do músico-historiador
Authors: Lima Lurian José Reis da Silva
Published: March 2019

Este artigo procura pensar uma história cultural da música a partir das implicações teórico-metodológicas da ideia de filosofia de Antonio Gramsci. As reflexões estão divididas em três etapas: (1) revisão de algumas vias abertas pela parceria entre história e antropologia em torno do conceito basilar de cultura; (2) análise da construção do conceito gramsciano de filosofia, sua relação com o projeto teórico mais amplo de Gramsci e com o olhar do autor sobre isto que os antropólogos/historiadores costumam chamar de cultura; (3) um diálogo entre Gramsci, antropologia e história cultural no esforço de fundamentar uma história cultural da música que privilegia o conflito simbólico/social. Tomo, como exemplo empírico desse exercício, uma pesquisa atual acerca do envolvimento de Villa-Lobos com músicos populares no Rio de Janeiro.
Comparative Analysis of Land Cover Classification Using ML and SVM Classifier for LISS-iv Data
Authors: Neware Rahul
Published: March 2019

This paper focuses on the crucial role that remote sensing plays in divining land features. Data that is collected distantly provides information in spectral, spatial, temporal and radiometric domains, with each domain having the specific resolution to information collected. Diverse sectors such as hydrology, geology, agriculture, land cover mapping, forestry, urban development and planning, oceanography and others are known to use and rely on information that is gathered remotely from different sensors. In the present study, IRS LISS IV Multi-spectral data is used for land cover mapping. It is known, however, that the task of classifying high-resolution imagery of land cover through manual digitizing consumes time and is way too costly. Therefore, this paper proposes accomplishing classifications by way of enforcing algorithms in computers. These classifications fall in three classes: supervised, unsupervised, and object-based classification. In the case of supervised classification, two approaches are relied upon for land cover classification of high-resolution LISS-IV multispectral image. These approaches are Maximum Likelihood and Support Vector Machine (SVM). Finally, the paper proposes a step-by-step procedure for optical image classification methodology. This paper concludes that in optical data classification, SVM classification gives a better result than the ML classification technique.

Recently, the concept of virtual data center (VDC) has attracted significant attention from researchers. VDC is made up of virtual nodes and virtual links with guaranteed bandwidth. It offers elasticity and flexibility, which means VDC can adjust resources dynamically according to different requirements. Existing studies focus on how to design the optimal embedding algorithm to achieve high success rate for the virtual data center request. However, due to the resource of physical data center changes over time, the optimal solution may become sub-optimal. In this paper, we study the problem of virtual data center migration and propose an energy-aware virtual data center migration algorithm, called CA-VDCM-ACO. This novel algorithm leverages the migration technique to further reduce the energy consumption with the success rate for the physical data center guaranteed. The extensive experiments show that our algorithm is very effective to reduce the energy consumption.

Authors: Zhang Bo ,   Information Technology Department, Beijing College of Politics and Law Beijing 102628, China
Published: March 2019

At present, ScanDisk is used to recover the data lost in network communication. But this method is limited in scope, and once the lost data is covered, it’s difficult or impossible to recover it, which results in low recovery degree. Accordingly, a recovery method for lost data in network communication based on RAID6 is proposed. Firstly, according to the mechanism of data loss in network communication, the missing data is divided into three categories: random loss, completely random loss and nonrandom loss, and then according to the results of classification, the recovery problem of the data loss in network communication is converted into the problem of matrix completion, finally, a low-rank decomposition model is proposed, according to the low rank characteristics of the matrix, the lost data in the matrix is recovered, thus the recovery of the lost data in network communication is finished. Experimental results show that the proposed method can easily recover the lost data in network communication with a simple operation, low computing complexity and strong applicability, and can be used as a universal recovery method for data lost in network communication.

Published: March 2019

Sharpening for dynamic images of remote network video is helpful to improve the dynamic images quality of remote network video and facilitate the subsequent use. Currently, most of remote network video dynamic images are completed based on the DSP chip, the cost of processing is high. In this paper, we propose a method to sharpen remote network video dynamic images based on the physical model. Firstly, image enhancement is carried out. Then, the dark channel priority method and the transmittance estimation method are analyzed to complete the sharpening. Experiments show that the proposed method can effectively improve the efficiency of image sharpening, and the sharpness of image is high and the practicability is strong.

Authors: Yi Tang-Tang ,   Department of Information Technology, Hunan Women’s University Changsha, Hunan 410004, China
Published: March 2019

In order to solve the problem of low recognition accuracy in recognition of 3D face images collected by traditional sensors, a face recognition algorithm for 3D point cloud collected by mixed image sensors is proposed. The algorithm first uses the 3D wheelbase to expand the face image edge. According to the 3D wheelbase, the noise of extended image is detected, and median filtering is used to eliminate the detected noise. Secondly, the priority of the boundary pixels to recognize the face image in the denoising image recognition process is determined, and the key parts such as the illuminance line are analyzed, so that the recognition of the 3D point cloud face image is completed. Experiments show that the proposed algorithm improves the recognition accuracy of 3D face images, which recognition time is lower than that of the traditional algorithm by about 4 times, and the recognition efficiency is high.

Authors: Et al. Malik
Published: March 2019

Seeds, beans, leaves, fruit peel and seeds of five plants (Ferula assa-foetida, Coffea robusta, Olea europaea, Punica granatum and Vitis vinifera, respectively) were extracted with four solvents (distilled water, 80% methanol, 80% acetone and a mixed solvent that included methanol, ethanol, acetone and n-butanol at proportions 7:1:1:1). Such manipulation yielded 20 extracts, which were phytochemically analyzed for total polyphenols (TP) and flavonoids (TF). The DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity (RSA) and DPP-4 (dipeptidyl peptidase-4) relative inhibition activity (RIA) were also assessed for each extract. The results revealed that mixed solvent extract of V. vinifera seeds showed the highest content of TP (194.8 ± 2.5 mg Gallic acid equivalent/g dry mass), while methanol extract of V. vinifera seeds recorded the highest content of TF (75.9 ± 0.3 mg catechin equivalent/g dry mass). The C. robusta bean aqueous extract was remarkable in scoring the highest DPPH RSA (87.2 ± 1.2%), while O. europaea leaf methanol extract had the highest DPP-4 RIA (86.4 ± 0.8%). In conclusion, the importance of natural products as radical scavengers and DPP-4 inhibitors is encouraged, and such biological effects were dependent on the plant species and the solvent of extraction. C. robusta beans are suggested to have a prominent RSA, while O. europaea leaves are recommended to be a target for investigations involved in the development of anti-T2DM therapies.

Roughness length is one of the key variables in micrometeorological studies and environmental studies in regards to describing development of cities and urban environments. By utilizing the three dimensions ultrasonic anemometer installed at Mustansiriyah university, we determined the rate of the height of the rough elements (trees, buildings and bridges) to the surrounding area of the university for a radius of 1 km. After this, we calculated the zero-plane displacement length of eight sections and calculated the length of surface roughness. The results proved that the ranges of the variables above are ZH (9.2-13.8) m, Zd (4.3-8.1) m and Zo (0.24-0.48) m.
A Study on the Accuracy of Prediction in Recommendation System Based on Similarity Measures
Authors: Et al. AL-Bakri
Published: March 2019

Recommender Systems are tools to understand the huge amount of data available in the internet world. Collaborative filtering (CF) is one of the most knowledge discovery methods used positively in recommendation system. Memory collaborative filtering emphasizes on using facts about present users to predict new things for the target user. Similarity measures are the core operations in collaborative filtering and the prediction accuracy is mostly dependent on similarity calculations. In this study, a combination of weighted parameters and traditional similarity measures are conducted to calculate relationship among users over Movie Lens data set rating matrix. The advantages and disadvantages of each measure are spotted. From the study, a new measure is proposed from the combination of measures to cope with the global meaning of data set ratings. After conducting the experimental results, it is shown that the proposed measure achieves major objectives that maximize the accuracy Predictions.
Advanced Signal Analysis of an Electrical-Submersible-Pump Failure Owing to Scaling
Authors: Noui-Mehidi M. N. , Bukhamseen A. Y.
Published: March 2019

In this paper we focus on electrical-submersible-pump (ESP) failure caused by scale buildup. Weak fluctuations recorded in the motor current signals several weeks before a failure indicate a change in the motor load. Advanced signal analysis of the motor current data reveals the presence of a dynamic characteristic in the ESP signal during rapid scale buildup in the pump stages. On the basis of the raw data from the motor current draw, a dynamic cascade can be identified in the current marked with the superimposition of several characteristic frequencies added over time that develop into a chaotic trend. Our analysis was conducted with different signal-processing tools, such as Fourier transform, wavelet transform, and chaotic attractors, which described the nature of the scale signature in the current logs. This analysis was the first step toward developing a real-time diagnostic tool for predicting ESP failures.
Developing Efficient Emulsifiers for Improved Fluid Stability from Highly Variable Raw Materials: Performance Analysis and Field Application
Authors: Maghrabi Shadaab , Smith Delores , Engel Aaron , Henry Jennifer , Fandel Joseph
Published: March 2019

This presentation demonstrates further development of efficient primary and secondary emulsifiers for invert emulsion (oil-based) drilling fluids. These primary and secondary emulsifiers were developed from two separate refinery side streams of crude tall oil (CTO). Due to the high degree of compositional variation in these selected side streams, they were not historically considered for product development. We managed the composition variation challenge by setting precise specifications and connecting aspects of product composition with desired performance in the drilling fluid application.

These side streams were derivatized under engineered reaction conditions to develop the efficient primary and secondary emulsifiers without compromising performance. Overall, detailed testing was performed to determine the emulsifier performance in different base oils (mineral oil and diesel), at different mud weights (12 – 16 ppg), at elevated temperatures, and in different fluid systems characterized by rheology and high-pressure, high-temperature (HPHT) fluid loss. Physical properties including product viscosity and pour points were also determined.

The developed efficient primary and secondary emulsifiers performed on par or outperformed the industry-available emulsifiers tested in this study. The efficient primary emulsifier demonstrated lower pour points and lower product viscosity as compared to the industry standards tested in this study. A new field application of this efficient primary emulsifier in the U.S. will be presented. On the other hand, the secondary emulsifier provided stable rheology with improved controlled fluid loss as compared to the industry standards in both conventional and polymer fluids. The emulsifier package of the developed efficient primary and secondary emulsifiers provided stable fluids in various fluid systems which were composed of different viscosifiers and fluid loss additives (FLAs).

The efficient primary and secondary emulsifiers were developed from highly variable raw materials. The physical properties of the primary emulsifier present it as a valued candidate for cold climate since it's easy to handle. The efficient secondary emulsifier can provide stable rheology with controlled fluid loss. The emulsifier package gave comparable performance across different fluid systems. This manuscript is a continuation of our previous research (Maghrabi et al. 2018).

Published: March 2019

Introduction: To report a case of unilateral peripheral cone dysfunction syndrome and evaluate the associated clinicopathological changes using swept-source optical coherence tomography (SS-OCT).
Case Presentation: A 39-year-old Japanese woman reported a visual field defect of 2-years duration in the right eye. The patient underwent visual field testing, full-field electroretinography (ff-ERG), SS-OCT, and a routine ophthalmologic examination. The best-corrected visual acuity was 20/20 bilaterally. The funduscopy examination was normal bilaterally. Visual field testing showed a relative paracentral scotoma in the right eye. SS-OCT scans showed an unclear interdigitation zone (IZ) throughout the posterior pole except for the foveal zone in the right eye. SS-OCT macular analysis showed thinning of the ganglion cell layer (GCL) and inner plexiform layer (IPL) corresponding to the region of the IZ defect. ff-ERG showed almost normal flash ERGs and normal rod responses bilaterally. The cone response and flicker ERG response were decreased markedly only in the right eye.
Conclusion: To the best of our knowledge, this is the first case report of unilateral peripheral cone dysfunction syndrome in which SS-OCT showed pathological changes in the GCL and IPL. The OCT findings corresponded well to the ERG changes and visual field abnormality. Because foveolar cone photoreceptor cells are connected in a one-to-one correspondence to retinal ganglion cells without connection to the horizontal cells or amacrine cells, the GCL and IPL were not present in the fovea. Based on this analysis, we speculated that the primary lesion of peripheral cone dysfunction syndrome is not in the cone photoreceptor cells but in the horizontal cells and/or amacrine cells. The clinicopathological changes in the ganglion cells and cone photoreceptor cells might be the subsequent pathologies in the horizontal cells in peripheral cone dysfunction syndrome.

Authors: Kong De-Zheng , Lian Ya-Hui , Wang Lin-Jing , Wang Chun-Mei , Meng Yang-Yang , Zhou Hong-Wei
Published: March 2019

Background

Fabry disease is rare, and often the diagnosis is delayed. Here, we describe a case of Fabry disease resulting in vasculopathy of the central nervous system. Magnetic resonance (MR) black-blood sequence (three-dimensional T1 volumetric isotropic turbo spin echo acquisition), with a unique advantage of imaging the vascular wall, facilitated a clear identification of the vasculopathy.

Case presentation

A 27-year-old man visited our hospital for the treatment of " double vision 6d." After a series of examinations, the patient was diagnosed with Fabry disease, which caused vasculopathy of the central nervous system. Subsequently, the patient was treated with corticosteroids and his symptoms were attenuated. Two months after the initial treatment, the initial lesion formed in the vascular vessel disappeared, however, a new lesion appeared. Similarly, four months after the initial treatment, although the previous lesion disappeared, a new lesion appeared.

Conclusions

This case highlights that clinicians should use MR black-blood sequence scan in a timely manner in case of young patients with repeated strokes and migratory lesions. In case of detection of a vascular lesion in combination with other systemic lesions, the possibility of Fabry disease should be considered.

Published: March 2019

Background: Spine surgery is associated with considerable postoperative pain and can be challenging to treat. A loco-regional technique suitable for spine surgery should cover the dorsal root of the spinal nerves at the levels where surgery is performed. The erector spinae block is a loco-regional technique with promising results that was recently described at the thoracic level. There are no randomized trials of this technique on a lumbar level. This study tests the hypothesis that the 24hour postoperative morphine consumption is significantly lower in patients undergoing posterior lumbar inter-body fusion surgery with a lumbar erector spinae (LUMBES) block when compared to a sham block. Methods: This prospective randomized double-blind multicentre study will randomly allocate 80 adult patients undergoing elective posterior lumbar inter-body fusion surgery during general anaesthesia to one of two groups as follows: 1. bilateral erector spinae block (20 mL 0,25% levobupivacaine) or 2. bilateral sham block (20 ml NaCl 0,9% ). Our primary endpoint is the 24 hour postoperative morphine consumption. Secondary endpoints include: 72-hour morphine consumption, intraoperative sufentanil dosage, postoperative pain scores at regular time intervals both at rest and during movement, time to first post-operative mobilization and the Quality of Recovery 40 score. Discussion: The LUMBES trial is a pragmatic clinical study that will provide evidence of whether a bilateral lumbar erector spinae block is effective in reducing 24 hour postoperative morphine consumption in patients undergoing lumbar inter-body fusion surgery. If this hypothesis is confirmed, this finding could contribute to more widespread implementation of this technique.

Cam lifi
taze beton karışımına eklenerek betonun mekanik özellikleri
iyileştirilmektedir. Literatürde cam lif takviyeli betonun (CTB) mekanik
özelliklerinin tespitine yönelik çok sayıda araştırma yapılmıştır. Beton içine
cam lifi eklenerek özellikle betonun eğilme ve çekme dayanımında hatırı sayılır
artışlar meydana gelmekte, bu şekilde üretilmiş olan betonlar daha ince kesitli
oldukları için de uygulamada tercih edilmektedirler. Betonun içine eklenen cam
lifinin betonun yangın performansına olumsuz bir etki yapıp yapmadığına yönelik
kapsamlı bir araştırma olmadığı için bu çalışmada dört farklı (30,60, 90 ve 120
dk) yangın sürelerine tabi tutulmuş cam lif takviyesiz beton ile CTB
elemanlarının yangın sonrasındaki mekanik özelliklerindeki değişiklikler
incelenmiştir. Deneysel çalışma kapsamında Ø15/30 cm silindir ve 4x4x16 cm
prizmadan oluşan toplam 300 adet numune üretilmiştir. Numunelerde kullanılan
0,5,10,15 ve 20 kg/m3 oranlarındaki cam elyaf takviyeli betonların
değişik sürelerde yangın sonrasındaki basınç ve üç farklı çekme (yarma, tek
noktadan eğilme ve iki noktadan eğilme) dayanımı üzerindeki etkisi farklı
sürelerde yangına maruz bırakılan CTB elemanları üzerinden test edilmiştir.
Yangın geçirmemiş numunelerde cam lifi basınç dayanımına bir katkıda
bulunmazken çekme dayanımında önemli oranlarda katkısı olmuştur. 30 dakikalık
yangın sonrasında CTB numunelerin tek ve çift noktadan eğilme deneylerinden
elde edilen çekme dayanımlarında yangın öncesine göre bir artış görülmüştür.
Daha uzun süreli yangınlarda (60, 90 ve 120 dk) ise bu oranda bir artış meydana
gelmemiştir.

Published: March 2019

Prostaglandinanalogues (PAs) are the drugs of choice in the treatment of primary open-angle glaucoma (POAG). However, they have pro-inflammatory properties and may cause macular edema. Tafluprost is the first PA to be free of preservatives. The efficacy and safety of tafluprost, as well as that of tafluprost/timolol fixed combination (FC), was demonstrated in randomized multicenter trials. However, there are no literary data concerning the effect of tafluprost and its FC on the thickness of the macula.Purpose. To assess the effect of tafluprost and tafloprost/timolol on the retinal thickness in the macular area in patients with POAG.Material and methods. The retinal thickness (RT) was measured with an interval of a week in 36 patients (36 eyes) with a newly diagnosed initial stage of POAG, 12 of whom were prescribed taflotan, 12 patients received tafluprost/timolol FC, and 12 eyes represented the control group (no drugs were prescribed). The measurements were performed in the macular area using a spectral domain optical coherence tomography (SD-OCT) by means of the RtVue xR Avanti with the AngioVue OCT angiography function. The change in the intraocular pressure (IOP) and RT from the inner limiting membrane (ILM) to the inner plexiform layer (inner retina) and to the pigment epithelium (PE) in fovea and parafovea in total and by sectors were estimated by comparing paired repeated observations using the median growth analysis.Results. In the tafluprost group, a 19.4 % IOP decrease was revealed and in the tafluprost/timolol group the decrease achieved 43 % with respect to the reference level. In patients receiving tafluprost, an increase in the RT in parafovea was noted: median growth 2 μm (p = 0.035); and in patients receiving tafluprost/timolol — in the inner layers of parafovea: median growth 3 μm (p = 0.031), and its inferior half: median growth 2.5 μm (p = 0.023). These changes were obtained in 10 patients out of 12 in each treated group. In untreated patients, the RT remained unchanged. The visual acuity did not change in any group of patients.Conclusions. In patients with glaucoma, a thickening of both the inner layers and the entire macular retina occurred within a week after treating with tafluprost or its FC, leaving no clinical manifestation. This fact should be taken into account in patients likely to develop macular edema.
Tables for near vision examination in low vision patients
Authors: Egorova T. S.
Published: March 2019

Purpose: to design methods and algorithms of technical means selection for near visual work in low vision patients. We propose tables to measure near vision acuity ranging from 0.01 to 0.8, with test character sizes varying in logarithmic progression with 1.26 denominator. The tables help determine the minimal size of readable font = the reading threshold and magnification degree needed to ensure the reading of a normal font. To choose the optimal magnifier, a quantitative criterion was chosen — the reading rate. Due to these methods we were able to recommend the most effective technical means of rehabilitation for monocular or binocular use depending on the reading threshold, reading rate, the presence of ophthalmic pathologies and the patient’s age.

Published: March 2019

The quadripartite nonaggression pact signed on July 8,
1937 in the Saadabad Palace of the Iranian Shah in Tehran, which ended the long
process of formation of a regional political group comprising Turkey, Iraq,
Iran and Afghanistan, was named by the contemporaries, and later in the
scientific literature, "Saadabad Pact". The mere fact of the
formation in the Middle East of a political bloc of states at a time when the
gradual "crawling" of mankind and individual states in World War II
is of considerable interest to the historian. However, the history of the
creation of the Saadabad Pact remained for a long time a little-known and
weakly studied topic. Meanwhile, the tendencies towards rapprochement and
cooperation in the relations of the countries of the Middle East are still in
effect. In this regard, knowledge of the history of the emergence, existence
and influence on international relations of regional groups such as the Saadabad
Pact becomes important. The Speaker sought to clarify the prerequisites and
reasons for the formation of the Saadabad Pact in the light of the development
of international relations in the Middle East, to determine the stages in the
formation of this regional grouping, to show the attitude of the great powers,
especially the Soviet Union and Britain, to it, and clarify the role of its
individual participants in the creation of the pact.

Real-time data assimilation potential to connect micro-smart water test bed and hydraulic model
Authors: Li Jiada , Bao Shuangli , Burian Steven
Published: March 2019

Recently, smart water application has gained worldwide attention, but there is a lack of understanding of how to construct smart water networks. This is partly because of the limited investigation into how to combine physical experiments with model simulations. This study aimed to investigate the process of connecting micro-smart water test bed (MWTB) and a ‘two-loop’ ENAPENT hydraulic model, which involves experimental set-up, real-time data acquisition, hydraulic simulation, and system performance demonstration. In this study, a MWTB was established based on the flow sensing technology. The data generated by the MWTB were stored in Observation Data Model (ODM) database for visualization in RStudio environment and also archived as the input of EPANET hydraulic simulation. The data visualization fitted the operation scenarios of the MWTB well. Additionally, the fitting degree between the experimental measurements and modeling outputs indicates the ‘two-loop’ ENAPNET model can represent the operation of MWTB for better understanding of hydraulic analysis.

Authors: Moghimi Mohammad Mehdi , Zarei Abdol Rassoul , Mahmoudi Mohammad Reza
Published: March 2019

Confronting drought and reducing its impacts requires modeling and forecasting of this phenomenon. In this research, the ability of different time series models (the ARIMA models with different structures) were evaluated to model and predict seasonal drought based on the RDI drought index in the south of Iran. For this purpose, the climatic data of 16 synoptic stations from 1980 to 2010 were used. Evaluation of time series models was based on trial and error. Results showed drought classes varied between ‘very wet’ to ‘severely dry’. The more occurrence frequency of ‘severely dry’ class compared to other drought classes represent the necessity of drought assessment and the importance of managing the effects of this phenomenon in the study area. Results showed that the highest severity of drought occurred at Abadeh, Shiraz, Fasa, Sirjan, Kerman, Shahre Babak and Saravan stations. According to selecting the best model fitted to the computed three-month RDI time series, results indicated that the MA model based on the Innovations method resulted in maximum cases with the best performance (37.5% of cases). The AR model based on the Yule–Walker method resulted in minimum cases with the best performance (6.3% of cases) in seasonal drought forecasting.

Published: March 2019

The present work studies the destruction of a silica-free solution of alkaline hydrolysate of rice husk (pH 7.25, COD = 22.8O g·L−1) using the photo-Fenton process in the UV layer at a wavelength of 365 nm. Oxidation of lignin was carried out at a constant mass ratio of COD:H2O2 = 1:2 in the solutions with different dilution times (1:10, 1:50) and with varying iron(II) concentrations in the range from 10 to 100 mg·L−1. It was established that the oxidative degradation of alkaline lignin effectively proceeds in the UV layer when the solution is diluted 50 times, at an iron(II) concentration from 50 to 70 mg·L−1. Color, the content of polyphenols and chemical oxygen demand in the silica-free solution with a dilution ratio of 1:50, after oxidation, is reduced by several tens of times. The products of lignin degradation were identified using gas chromatography.
Highly efficient and selective removal of tetracycline from aqueous solutions via adsorption onto Cu(II)-modified hierarchical ZSM-5
Authors: Fan Subing , Lv Junmin , Ma Yulong , Chen Yaoyao
Published: March 2019

Herein, we prepared Cu(II)-modified hierarchical ZSM-5 containing both micro- and mesopores by alkali treatment followed by ion exchange as an adsorbent, using it for tetracycline (TC) removal from aqueous solutions. The crystal structure, morphology, texture, and Si:Al ratio of this adsorbent by a range of instrumental techniques were investigated. Moreover, we studied the effect of pH and Cu(II) loading on adsorption performance and probed adsorption kinetics, thermodynamics and regeneration performance, revealing that modification of hierarchical ZSM-5 with Cu(II) not only significantly increased its TC removal efficiency but also allowed for good regenerability and suggested that the highly efficient and selective removal of TC from aqueous solutions could be ascribed to not only the strong interactions between Cu(II) and TC molecular but also the larger mesoporosity.

Authors: Strokatov Denis A.
Published: March 2019

In October 2018 an updated Global Competitiveness Index (GCI) 4.0 was introduced in the Global Competitiveness Report2018. Inthe article identify the main differences in the structure and methodology of calculating GCI in the editions of the Global Competitiveness Report 2017–2018 and the Global Competitiveness Report2018. Areview of a number of sources showed that researchers don’t pay enough attention to innovations in the structure and methodology of calculating GCI 4.0. As a result of analyzing the structure and methodology of calculating GCI 4.0, it was revealed that a number of adjustments were made in the Index aimed at marking the importance of the Fourth Industrial Revolution, equalization the conditions when calculating the Index for countries at different stages of development, and taking into account current tendencies of the world economy. In conclusion, the author emphasizes that these innovations have reduced the high degree of subjectivity of the GCI, eliminated a number of difficulties in independent determining the value of the Index and increased the transparency of the calculations.
Screening and Identification of PLK1-Polo Box Binding Peptides by High-Throughput Sequencing of Phage-Selected Libraries
Authors: Bibi Nousheen , Niaz Hafsa , Hupp Ted , Kamal Mohammad Amjad , Rashid Sajid
Published: March 2019

Background:

Human proteome contains a plethora of short linear peptide motifs that is
crucial for signaling and other cellular processes. These motifs are difficult to identify due to lack
of systematic approach for their detection.

Objective:

Here we demonstrate the use of peptide phage display in combination with high
throughput next generation sequencing to identify enriched peptide sequences through biopanning
process against polo box domain (PBD) of mitotic polo like kinase 1 (Plk1).

Methods:

Purified recombinant Plk1 and two unrelated controls namely B-lymphocyte antigen
(CD20) and fluorescent protein (mCherry) were subjected to peptide phage display analysis.
Bacterially-propagated phage DNA was amplified by PCR using triplet bar coded primers to tag the
pool from each amplicon.

Results:

Proteomic peptide phage display along with next generation sequencing and
Bioinformatics analysis demonstrated several known and putative novel interactions which were
potentially related to Plk1-PBD. With our strategy, we were able to identify and characterize
several Plk1-PBD binding peptides, as well as define more precisely, consensus sequences.

Conclusion:

We believe that this information could provide valuable tools for exploring novel
interaction involved in Plk1 signaling as well as to choose peptides for Plk1 specific drug
development.
Synthesis and Application of Stable Nitroxide Free Radicals Fused with Carbocycles and Heterocycles
Authors: Bognár Balázs , Úr Györgyi , Sár Cecília , Hankovszky Olga H. , Hideg Kálmán , Kálai Tamás
Published: March 2019

Stable nitroxide free radicals have traditionally been associated with 2,2,6,6-
tetramethylpiperidine-1-oxyl (TEMPO) or its 4-substituted derivatives as relatively inexpensive
and readily accessible compounds with limited possibilities for further chemical
modification. Over the past two decades, there has been a resurgence of interest in stable
free radicals with proper functionalization tuned for various applications. The objective of
this review is to present recent results with synthetic methodologies to achieve stable nitroxide
free radicals fused with aromatic carbocycles and heterocycles. There are two
main approaches for accessing stable nitroxide free radicals fused with arenes, e.g., isoindoline-
like nitroxides: further functionalization and oxidation of phthalimide or inventive
functionalization of pyrroline nitroxide key compounds. The latter also offers the constructions
of versatile heterocyclic scaffolds (furan, pyrrole, thiophene, 1,2-thiazole, selenophene, pyrazole,
pyrimidine, pyridine, pyridazine, 1,5-benzothiazepine) that are fused with pyrroline or tetrahydropyridine nitroxide
rings. The possible applications of these new stable nitroxide free radicals, such as covalent spin labels
and noncovalent spin probes of proteins and nucleic acids, profluorescent probes, building blocks for construction
of dual active drugs and electroactive materials, and substances for controlled free radical polymerization,
are discussed.
Development and Characterization of Water-in-Oil Microemulsion for Transdermal Delivery of Eperisone Hydrochloride
Authors: Kumbhar Monika D. , Karpe Manisha S. , Kadam Vilasrao J.
Published: March 2019

Background:

Eperisone hydrochloride possesses short biological half-life due to first
pass metabolism resulting in low bioavailability and short duration of response with toxic effects,
ultimately limits its utilization for treatment of muscle spasm.

Objective:

In view of this background, current study was designed for the development of Eperisone
hydrochloride-loaded microemulsion and Eperisone hydrochloride-loaded microemulsion
based cream for topical delivery and compared it with conventional cream.

Methods:

Firstly, water-in-oil microemulsion was prepared by spontaneous emulsification method.
The concentration of components was found out from existence of microemulsion region by
constructing pseudoternary phase diagram. The oil was selected on the basis of drug solubility effect
on the drug release, whereas surfactant and cosurfactant were screened on the basis of their
efficiency to form microemulsion region. The influence of components on microemulsion formation,
drug release capacity, permeation was studied by differential scanning calorimetry, X-ray
diffraction, in-vitro release and ex-vivo drug permeation studies respectively. By using microemulsion,
the cream was prepared for proving optimum structure for topical application.
Microemulsion was evaluated for droplet size, zeta potential, pH, viscosity and conductivity. Besides
the cream was characterized for pH, rheology and stability. Permeation of EPE from microemulsion
across the rat skin was evaluated and compared with conventional cream.

Results:

The microemulsion consisting Isopropyl Myristrate/Water/Span 80:Tween 80 (50/8/42%
by weight) possessed droplet size of 95.77nm, zeta potential of −5.23 mV with 7.25 pH and conductivity
near to zero (<0.05mScm-1). Physical parameters of the cream were satisfactory, also
2.33-fold higher permeation and 1.57-fold higher release observed as compared to conventional
cream.

Conclusion:

It can be concluded that Eperisone hydrochloride-loaded microemulsion and its
cream is being effectively used for muscle spasticity by topical route.
