Abstract
Islamic education is a process to help society be a human being perfectly to know Allah by using the Qur’an and al-Hadith, the source of their live. Creating an Environmet of Islamic community is an effort has been made with the “Greeting Gate” Jargon or the Islamic Community Development Movement which is then revealed in the form of applications and implementation in community, include the world of education. Islamic community environmental creation techniques have been carried out since 2002/2003 by the government and the community and religious leaders represented by other religious organizations. Thus, the creation on an environment of Islamic community is the purpose of the government; that the Islamic spirit and attitude be a culture for the entire community in Pamekasan district. On the other hand, the community is a pluralistic society consisting of various tribes, races and ethnicities, such as indigenous, Chinese and Arabic, to achieve the success of creating an Islamic society, the education process is needed to bridge it, and multicultural education is the most approprite way to apply in the Enviroment of Islamic Community. The research method used is naturalistic qualitative research, data collection techniques using several instruments, interview data, documentation data and observations. The results of the research conducted, can be explained that multi-cultural education can help and sustain the success of the Greeting Gate’s program or the creation of an Islamic community environment; however, some education’s components can not support and understand the multicultural education.

Published: April 2020

Annotation
The problem of determining and possible ways to reduce the amplitude of torque ripples in a vane pneumatic motor without a significant reduction of its energy efficiency is considered. This problem is important for improving the ergonomic performance of manual mechanized pneumatic tools and improving the accuracy of pneumatic servosystems. The results are presented for the traditional layout scheme of a vane pneumatic motor, as well as for the proposed modified design. The decision was made using a detailed mathematical model of a pneumatic motor. The prospects of the modified pneumatic motor to reduce the torque ripples at higher energy efficiency indicators are shown, compared with the original model with an increased number of vanes.

Hydrodynamic modeling of cavitation in a multistage centrifugal pump during its operation in the constant feed mode with a change in the rotor speed of the pump
Authors: Kasatkin M , Petrov A 
Published: April 2020

Abstract
Hydrodynamic modeling of cavitation for a multi-section high-speed centrifugal pump operating at a constant supply is carried out. The cavitation characteristics of the pump for various pump operating modes are determined taking into account changes in the rotor speed. The operation parameters of the mobile pumping system for these modes are calculated. It has been established that improving the cavitation qualities of a pump by reducing the speed of the pump rotor with a constant flow rate is not a productive method.

Study the densification behavior and cold compaction mechanisms of solid particles-based powder and spongy particles-based powder using a multi-particle finite element method
Authors: Korim Nada S , Hu Lianxi 
Published: April 2020

Abstract
Powders could be based on solid particles or spongy particles depending on the powder manufacturing procedures. In this article, the numerical study of the cold compaction process for copper solid particles-based powder (i.e. Cu solid powder) and spongy particles-based powder (i.e. Cu sponge powder) has been carried out by using a two-dimensional multi-particle finite element method (2D-MPFEM) based on single action die compaction. The effects of internal pores content, external pressure, initial packing structure on the packing densification were systematically presented. Relative density, stress distribution, internal pore deformations, and force chain movements, particle rearrangement, and interfacial behavior within spongy particles were characterized and analyzed. The results reveal that the densification behavior of the sponge powder depends basically on the internal pore’s content. Moreover, at low and medium relative density (ρ < 0.95), the densification behavior of the sponge powder is faster than solid particles-based powder. However, at higher relative density near unity, the force required to cause further compaction is significantly larger in the sponge powder. In addition, from the microscopic analysis, the deformation behavior of the particles and the internal pores and the force chain development rely mostly on the structure configuration, internal pore content and its position.
Wetting behavior of textured silicon surfaces- an experimental study
Authors: K Mohan Kumar , Velmurugan V 
Published: April 2020

Abstract
The behavior of a liquid on a solid surface has shown great interest in a variety of applications related to surfaces and its interfaces. In this paper, the wetting behavior of DI water on micropatterned silicon surfaces fabricated through photolithography and deep reactive ion etching (DRIE) is investigated. Micro pillars of both solid and hollow geometries at a varying pitch and its arrangement in an array has been examined with static contact angle measurement. However, the results concluded that the arrangement of pillars in an array plays an important role as hollow geometries in the case of chain type arrangement provide both hydrophilic and hydrophobic surface properties, while the same hollow geometries in case of zig-zag orientation experiences only hydrophobicity at a varying pitch. Decreased WCA with increased pitch has been observed in the case of a zig-zag arrangement, due to the effect of capillary and gravitation forces. Also the existence of air pockets at sharp corner in the case of hollow square assists in providing maximum contact angle (WCA = 144°) as compared to hollow circle and solid geometries; thus a non-sticky behavior would be possible between the droplet and the patterned surface, due to less adhesion force.

Abstract
Green synthesis technique of nanoparticles has advantages over physical and chemical methods due to its simplicity in preparation, environment friendly nature and less time consuming. We report a green approach for the synthesis of zincoxide nanoparticles using leave extract from melia azedarach. Melia azedarach plant has been traditionally famous for its antibacterial properties. The plant extract acts as reducing and capping agent, while zinc nitrate hexahydrate [Zn(NO3)2.6H2O] was used as a precursor. The formation of ZnO nanoparticles was observed by the color changes during the reaction. Structural, optical and morphological properties of ZnO nanoparticles were determined using x-ray diffraction, scanning electron microscope, Fourier transform spectroscopy and UV–vis spectroscopy. XRD analysis confirms the formation of wurtzite hexagonal structure NPs with significantly small average crystallite size of 7.0 nm. The energy band gap determined by UV–vis spectroscopy was measured between 2.9 eV to 5.4 eV. The antibacterial activity of ZnO nanoparticles was tested against E. coli bacteria and significant results were obtained. The anti-bacterial study proved that green-rout prepared ZnO nanoparticles are the best choice for future research concerning antibacterial activity.
Evaluation of gene–drug common module identification methods using pharmacogenomics data

Published: April 2020

Abstract
Accurately identifying the interactions between genomic factors and the response of cancer drugs plays important roles in drug discovery, drug repositioning and cancer treatment. A number of studies revealed that interactions between genes and drugs were ‘many-genes-to-many drugs’ interactions, i.e. common modules, opposed to ‘one-gene-to-one-drug’ interactions. Such modules fully explain the interactions between complex biological regulatory mechanisms and cancer drugs. However, strategies for effectively and robustly identifying the underlying common modules among pharmacogenomics data remain to be improved. In this paper, we aim to provide a detailed evaluation of three categories of state-of-the-art common module identification techniques from a machine learning perspective, including non-negative matrix factorization (NMF), partial least squares (PLS) and network analyses. We first evaluate the performance of six methods, namely SNMNMF, NetNMF, SNPLS, O2PLS, NSBM and HOGMMNC, using two series of simulated data sets with different noise levels and outlier ratios. Then, we conduct experiments using a real world data set of 2091 genes and 101 drugs in 392 cancer cell lines and compare the real experimental results from the aspect of biological process term enrichment, gene–drug and drug–drug interactions. Finally, we present interesting findings from our evaluation study and discuss the advantages and drawbacks of each method.

Published: April 2020

Abstract
Dried blood spots (DBS) are widely utilized as part of universal newborn screening and as a means of transporting samples from field sites. We use DBS from African field sites to assess for rare maternal-fetal cell exchange during pregnancy known as microchimerism. We aimed to develop a protocol to maximize the quantity of high-quality genomic DNA (gDNA) extracted from DBS. The total gDNA yield obtained from control DBS utilizing a Qiagen-based protocol and a Chelex® 100 resin-based protocol was first compared. Variations of the Chelex® protocol were subsequently tested to develop an optimized protocol. The gDNA was quantified by qPCR targeting the human beta-globin gene. DNA yield for a given experimental condition was normalized to a Chelex® control performed on the same day, and the total yields were compared using a Student’s t-test. The control Chelex® protocol yielded 590% more DNA than the QIAamp® DNA Blood Mini Kit . The absolute efficiency of the control Chelex® protocol was 54%, compared to an absolute efficiency of 9% for the QIAamp® DNA Blood Mini Kit. Modification of the Chelex® protocol to include a second heat precipitation from the same DBS increased the gDNA yield by 29% (P &lt; 0.001). Our optimized protocol including this modification increased the absolute efficiency of extraction to 68%. The gDNA extracted using the Chelex® protocol was stable through repeated freeze–thaw cycles. In a mock microchimerism experiment, rare donor alleles at a frequency of 10 in 100 000 could be identified in gDNA from DBS extracted using the optimized Chelex® protocol. Our findings may be of significance for a diverse range of applications that utilize DBS and require high-quality DNA, including newborn screening programs, pathogen and drug resistance screening from remote field sites, forensics, and rare allele detection.
Macroeconomic policies in Brazil before and after the 2008 global financial crisis: Brazilian policy-makers still trapped in the New Macroeconomic Consensus guidelines
Authors: Nassif André , Feijó Carmem , Araújo Eliane 
Published: April 2020

AbstractEven though the New Macroeconomic Consensus (NMC) guidelines have been under review by mainstream economists from developed countries since the 2008 global financial crisis, Brazilian policy-makers are still following these old recommendations. The NMC was adapted in Brazil in 1999 as a policy arrangement known as the macroeconomic tripod: a combination of inflation targeting, floating exchange rates and targets for the primary fiscal surplus. The theoretical basis of this policy arrangement is thus closely aligned to that of the NMC: a reduced (if any) role for fiscal policy and an exclusive focus on price stability for monetary policy. Particularly with respect to the experience of inflation targeting in Brazil, by implementing a vector autoregression model for the period 2000–17, we show that (i) inflation dynamics are mostly cost-push rather than demand-pull; (ii) inflation rates show low sensitivity to changes in interest rates; and (iii) the main variables negatively affected by an increase in the Brazilian policy rate are the nominal exchange rate (i.e. the Brazilian real tends to appreciate) and output growth. It follows that the macroeconomic tripod is unsuitable to the Brazilian economy, especially considering that, as it is also shown in this article, such arrangement has contributed to perpetuating trends of high real interest rates, domestic currency overvaluation and low economic growth in Brazil in the last two decades. The article ends calling for a new macroeconomic arrangement to reverse these adverse long-term trends.

Abstract

Aims
Circumferential pulmonary vein isolation can be effective as sole treatment for persistent atrial fibrillation. However, identifying those patients who will respond to this therapy remains a challenge. We investigated the clinical value of the sequential low-dose ibutilide test for identifying patients with persistent atrial fibrillation in whom pulmonary vein isolation is effective as sole therapy.

Methods and results
In a prospective cohort of 180 consecutive patients with persistent atrial fibrillation, intravenous low-dose (0.004 mg/kg) ibutilide was administered 3 days before ablation and after the completion of circumferential pulmonary vein isolation. In patients in whom ibutilide did not terminate atrial fibrillation pre-procedurally, but successfully terminated it intraprocedurally, no further atrial substrate modification was performed. Pre-procedural low-dose ibutilide failed to terminate the arrhythmia in all patients with persistent atrial fibrillation, while pulmonary vein isolation ± low-dose ibutilide terminated persistent atrial fibrillation in 55 (30.6%) of them (PsAF group 1). The remaining 125 (69.4%) patients underwent electrogram-based ablation (PsAF Group 2). The control group comprised 379 consecutive patients with paroxysmal atrial fibrillation who underwent pulmonary vein isolation over the same period. At 24 months follow-up, 39 (70.9%) patients in PsAF Group 1 and 276 (72.8%) patients in the control group were free from atrial tachyarrhythmias (P = NS); the arrhythmia-free rates in both groups were higher than that in PsAF group 2 (58.4%, P = 0.005).

Conclusion
The sequential low-dose ibutilide test is a simple method for identifying patients with persistent atrial fibrillation in whom pulmonary vein isolation alone is an appropriate treatment strategy.

Published: April 2020

Abstract

Background
Health 2020 is the regional health policy framework of the World Health Organization (WHO) Regional Office for Europe. The goals of Health 2020 are to improve health and well-being, reduce health inequalities and strengthen public health. To gain insight into the Health 2020 targets needing extra attention in coming years, we assessed progress under Health 2020 in the WHO European Region.

Methods
Quantitative methods were used to assess progress in 50 out of 53 Member States of the WHO European Region in 2005, 2010 and 2015. The 16 quantitative Health 2020 indicators were rescaled from 1 to 100, with 1 indicating poor performance and 100 indicating good performance. The geometric mean of all 16 rescaled indicators was taken by Health 2020 target to compose a Health 2020 index.

Results
The Health 2020 index (2015) ranged from 82.8 in Sweden to 30.0 in Turkmenistan. A clear east-west gradient was observed in the WHO European Region, with countries in western parts performing relatively better than countries in eastern parts. Indicators with the largest increase between 2005 and 2015 were premature mortality, mortality external causes, life expectancy and infant mortality. However, all quintiles showed a decline on overweight.

Conclusions
The Health 2020 index gives a relative overview regarding the past and present performance on the Health 2020 policy framework of countries in the WHO European Region. Although improvements have been observed between 2005 and 2015, challenges remain to improve health for all in the context of the United Nations 2030 Agenda for Sustainable Development.
