Fatwa is the answer to the problem that arises, usually respond to contemporary things. This can be seen from a series of fatwa issued by the MUI. from the problem golput, cigarettes, pre-wedding photos, motorcycle taxi women and many other things. Fatwa is a very urgent case for humans because not everyone is able to explore the laws of the Shari'a. Or it can be concluded that the fatwa is an explanation of Sharia law on various issues that occur in the midst of society.
Therefore, given the importance of the position of the fatwa, it should be done that the people do not ignore the fatwas issued by the Fatwa scholars born because of the consideration of the benefit of the ummah or mashalihul ummah, and in this paper will be discussed about the methods of law enforcement in berfatwa.
One of the conditions for determining fatwas is that they must fulfill the methodology (manhaj) in teaching, because it establishes fatwas without regard to manhaj including those which are prohibited by religion. Establish a fatwa based solely on the necessity (li al-hajah), or because of the benefit (li al-mashlahah), or because the essence of religious teachings (li maqashid as-syari'ah), with no adhering to nushus syar'iyah, including the excessive group (ifrathi).
Within the scope of the fatwa there are some important things that must be noticed by a mufti (giver of fatwas) and a mustafti (the person who asks fatwas) so that the resulting fatwa can be useful in solving a problematika. For the sake of perfection a fatwa of mustafti must use some method which must be consumed in solving problem which in ijtihadi at that time, like method bayani, ta'lili and termi.

Kekerasan yang semakin marak tidak hanya terjadi di jalanan saja. Ternyata di sekolahpun dilanda hal serupa. Bukan perkara baru jika murid mengalami kekerasan dari oknum di sekolah, atau sesama murid. Bahkan ada pula orangtua yang berduel dengan guru karena persepsi yang mereka miliki. Meskipun tidak separah dengan kekerasan di jalanan, namun kekerasan di sekolah efeknya bisa berdampak bagi psikhis anak didik. Trauma, stress, hingga depresi dapat mereka alami. Kebimbangan, Kejenuhan, serta ketakutan, menjadi bayang - bayang yang tak berkesudahan. Selanjutnya pendekatan humanis ini sebagai upaya agar kekerasan bisa dicegah. Minimal dapat dikurangi. Pendekatan dengan cara memanusiakan manusia, karena secara kodrati mereka diberi keunikan serta kemampuan yang beragam oleh Tuhan. Pendekatan humanis cenderung menggugah kepekaan sekolah, guru, murid, orangtua, masyarakat agar mampu membangun empati dan simpati atas keunikan dan kemampuan setiap manusia yang berbeda. Pendekatan humanis menjadi bagian dari aktivitas pendidikan mampu mengaktualisasikan ajaran agama (Islam) yang rahmatal lil ‘alamiin bagi semua makhluk. Sehingga dapat menumbuhkan perilaku menghargai, menghormati, menerima, orang lain secara optimal. Tujuan akhir dimaksudkan untuk mengabdikan diri kepada Tuhan, berguna untuk sesama, mampu memberi kemaslahan individu serta sosial secara harmonis dan seimbang.Kata kunci : kekerasan, humanis, dan sekolah

Published: January 2019

Abstract
Background: The problem of adulterated meat has become one of the greatest food safety issues in the world. It is reported that the meat used for adulteration includes fox meat, raccoon meat, mink meat, mouse meat, and so on. Although this kind of meat is edible in some areas, such meat is potentially harmful to human health because it is easy to carry bacteria, viruses, and harmful substances. The harm of mouse meat is most frightening. Therefore, it is urgent to develop a fast, accurate, and simple method to effectively identify mouse meat. Methods: In the present study, a new method of isothermal amplification based on the 16S ribosomal RNA gene of the mitochondrial DNA of the mouse was developed. The method is meant to improve the loop-mediated isothermal amplification (LAMP), separating the forward inner primers and backward inner primers, greatly reducing the nonspecific amplification of the method. Results: We have successfully obtained a set of best primers. The developed system allowed for the detection of 0.5% mouse meat from meat mixture effectively and specifically. The best ratio of the primers (F3: F2: F1: RF) was 1:2:2:8, and the optimum concentration of DNA template was 0.35 ng/μL. Conclusions: The assay has great specificity and sensitivity for detecting mouse meat and could provide specific positive results within 1 h. Highlights: We found a new approach of isothermal amplification to detect mouse source components. The LOD is determined to be 0.5 mg/mg. This new method is easy to perform and is able to provide rapid results in the specific detection of mouse meat sources.

Published: January 2019

Abstract
Background: Astragali radix is prone to be contaminated by various mycotoxins, leading to unpredictable threats on the quality and safety of Astragali radix and the health of the consumers. Therefore, the determination of multimycotoxins is imperative. Objective: To develop an efficient, sensitive, fast, and multianalyte method for detecting multimycotoxins in Astragali radix. Methods: A selective dilute-and-shoot pretreatment procedure based ultra-performance LC–tandem MS (UPLC-MS/MS) method was developed for sensitive determination of multimycotoxins in Astragali radix, including aflatoxin (AF) B1, B2, G1, G2, and ochratoxin A. The five mycotoxins were extracted by the dilute-and-shoot pretreatment procedure followed by UPLC-MS/MS detection. Types of sample extraction solvent, mobile-phase compositions and MS/MS parameters, and dilute-and-shoot conditions were optimized. Results: The optimized chromatographic and mass spectrometric conditions allowed the separation and detection of the five mycotoxins within 5 min. The validated UPLC-MS/MS method exhibited good sensitivity with LOD and LOQ lower than 0.2 and 0.5 μg/kg, respectively. RSD values for method precision were lower than 9%. Recoveries obtained were between 90.87 and 108.44% for all the analytes with RSDs of 3.96–8.03%. The developed method was applied for the detection of the 5 mycotoxins in 18 batches of Astragali radix with good determination performance and no matrix interferences. Two samples collected from Shanxi province and Neimenggu Autonomous Region in China were positive for AFB1 at 3.24 and 2.69 μg/kg, respectively. Conclusions: The dilute-and-shoot procedure allowed for the extraction of the mycotoxins with advantages of simple pretreatment, small extraction time, high selectivity and accuracy, as well as being cost effective and easy to operate without any clean-up steps. Highlights: This is the first report on dilute-and-shoot approach for mycotoxins extraction and detection in Chinese medicinal material matrixes.
Synthesis and Electronic Properties of Triperyleno[3.3.3]Propellanes: Towards Two‐Dimensional Electronic Structures
Authors: Kodama Takuya , Miyazaki Shogo , Kubo Takashi 
Published: January 2019

AbstractThreefold symmetric triperyleno[3.3.3]propellanes (TPRPs), which are composed of three perylene units peri‐fused on [3.3.3]proppellane, have been synthesized and their electronic properties characterized. Unsubstituted TPRP assembles into two‐dimensional honeycomb‐like networks. TPRP displays a bathochromic‐shifted absorption band in its absorption spectrum and shows well‐separated one‐electron redox waves in a cyclic voltammogram, due to a homoconjugative interaction between perylene moieties. A radical cation species of tert‐butyl substituted TPRP shows spin delocalization over the whole of the molecule, which is derived from effective overlap of HOMOs among three perylene moieties.

Published: January 2019

AbstractBACKGROUNDIt is difficult to efficiently silence gene expression in some insects, probably because of the degradation of dsRNA by enzymes present in the gut and hemolymph post‐oral feeding or body injecting of dsRNA. We previously developed a nanocarrier delivery system that can systemically deliver dsRNA into chewing mouthpart insects by oral feeding and efficiently silence gene expression. For the purpose of pest control in the field, there is a great demand to develop a spray method to apply dsRNA formulation.RESULTSA formulation of the nanocarrier/dsRNA/detergent was developed and could be easily applied just by dropping it on the notum of the aphid. The formulation penetrated the body wall into the hemocoel and then spread into various tissues within 1 h. The delivered dsRNA efficiently silenced the target gene expression at a high knockdown effect (95.4%) and the aphid population was largely suppressed (80.5%).CONCLUSIONA novel dsRNA formulation was developed with the help of a nanocarrier and detergent that can quickly penetrate the insect body wall and efficiently silence gene expression. The formulation may provide a fast and easy tool for gene silence in some tough insects and for pest control in the field. © 2019 Society of Chemical Industry
Aktuelle Forschung und Verwendbarkeit von reaktiven Brandschutzsystemen im Stahlbau
Authors: Schaumann Peter , Weisheim Waldemar 
Published: January 2019

AbstractReaktive Brandschutzsysteme finden im architektonischen Stahlbau eine stetig zunehmende Anwendung. Im Bestreben nach schlanken und architektonisch ansprechenden Konstruktionen weisen reaktive Brandschutzsysteme gegenüber anderen Brandschutzprodukten deutliche Vorteile auf. Durch ihre geringen Trockenschichtdicken erhalten die Brandschutzsysteme auf der einen Seite das filigrane Erscheinungsbild einer Stahlkonstruktion aufrecht. Auf der anderen Seite stellen sie gleichzeitig den geforderten Brandschutz sicher. Während noch vor einigen Jahren die Anwendung der Brandschutzsysteme ausschließlich auf druck‐ und biegebeanspruchten Bauteilen erfolgte, haben nationale Forschungsarbeiten zu einer Erweiterung des Anwendungsbereichs auch für Zugglieder geführt. Da die Verwendbarkeit der reaktiven Brandschutzsysteme derzeit in Deutschland durch nationale Zulassungen und europäische Bewertungen geregelt ist, stehen den Herstellern unterschiedliche Optionen für das Inverkehrbringen ihrer Produkte auf dem deutschen und europäischen Markt zur Verfügung. Im vorliegenden Artikel werden die Unterschiede der beiden Möglichkeiten des Inverkehrbringens der Produkte aufgezeigt und eine Übersicht über Forschungsarbeiten gegeben, die aktuell am Institut für Stahlbau der Leibniz Universität Hannover zur Leistungsfähigkeit von reaktiven Brandschutzsystemen bei Naturbränden durchgeführt werden. Die Forschungsergebnisse sind Teil des IGF‐Forschungsvorhabens 19176 N der Forschungsvereinigung Deutscher Ausschuss für Stahlbau e.V. (DASt).
Differential equations from unitarity cuts: nonplanar hexa-box integrals
Authors: Abreu Samuel , Page Ben , Zeng Mao 
Published: January 2019

AbstractWe compute ϵ-factorized differential equations for all dimensionally-regularized integrals of the nonplanar hexa-box topology, which contribute for instance to 2-loop 5-point QCD amplitudes. A full set of pure integrals is presented. For 5-point planar topologies, Gram determinants which vanish in 4 dimensions are used to build compact expressions for pure integrals. Using unitarity cuts and computational algebraic geometry, we obtain a compact IBP system which can be solved in 8 hours on a single CPU core, overcoming a major bottleneck for deriving the differential equations. Alternatively, assuming prior knowledge of the alphabet of the nonplanar hexa-box, we reconstruct analytic differential equations from 30 numerical phase-space points, making the computation almost trivial with current techniques. We solve the differential equations to obtain the values of the master integrals at the symbol level. Full results for the differential equations and solutions are included as supplementary material.
RETRACTED ARTICLE: Novel deep genetic ensemble of classifiers for arrhythmia detection using ECG signals
Authors: Pławiak Paweł , Acharya U. Rajendra 
Published: January 2019

AbstractThe heart disease is one of the most serious health problems in today’s world. Over 50 million persons have cardiovascular diseases around the world. Our proposed work based on 744 segments of ECG signal is obtained from the MIT-BIH Arrhythmia database (strongly imbalanced data) for one lead (modified lead II), from 29 people. In this work, we have used long-duration (10 s) ECG signal segments (13 times less classifications/analysis). The spectral power density was estimated based on Welch’s method and discrete Fourier transform to strengthen the characteristic ECG signal features. Our main contribution is the design of a novel three-layer (48 + 4 + 1) deep genetic ensemble of classifiers (DGEC). Developed method is a hybrid which combines the advantages of: (1) ensemble learning, (2) deep learning, and (3) evolutionary computation. Novel system was developed by the fusion of three normalization types, four Hamming window widths, four classifiers types, stratified tenfold cross-validation, genetic feature (frequency components) selection, layered learning, genetic optimization of classifiers parameters, and new genetic layered training (expert votes selection) to connect classifiers. The developed DGEC system achieved a recognition sensitivity of 94.62% (40 errors/744 classifications), accuracy = 99.37%, specificity = 99.66% with classification time of single sample = 0.8736 (s) in detecting 17 arrhythmia ECG classes. The proposed model can be applied in cloud computing or implemented in mobile devices to evaluate the cardiac health immediately with highest precision.
Effects of Coastal Upwelling and Downwelling on Hydrographic Variability and Dissolved Oxygen in Mobile Bay
Authors: Coogan Jeffrey , Dzwonkowski Brian , Lehrter John 
Published: January 2019

AbstractUpwellling and downwelling events are important coastal processes that strongly influence shelf ecosystem dynamics. Though changes on the shelf have been well studied, the impact of these events on estuarine systems has received less focus. In summer 2016 a downwelling and upwelling event were observed near the mouth of Mobile Bay. The impact of these events were examined throughout the bay with high spatial resolution observations. Five boat surveys were conducted to capture the spatial response of offshore forcing and its changes in the estuary. In addition to the surveys, 16 conductivity, temperature, and depth (CTD) sensors were deployed and measured temporal changes. A 7 ° C temperature change was observed in the channel as a result of the offshore changes. In the shipping channel and offshore, advection was a major source of changes in heat content and often exceeded the surface heat flux. Advection of low dissolved oxygen water into the estuary was also observed in the shipping channel and at the Dauphin Island station nearest to the estuary mouth. The extent of these changes highlights the importance of estuary‐shelf connectivity in river‐dominated systems where offshore forcing can drive large changes in estuaries during low flow summer conditions.
Single-molecule imaging of the transcription factor SRF reveals prolonged chromatin-binding kinetics upon cell stimulation

Published: January 2019

Significance
How transcription factors (TFs) activate transcription is a long-standing but still unsolved question. We analyzed serum response factor (SRF), a stimulus-responsive TF mediating immediate early gene (IEG) and cytoskeletal gene expression at single-molecule resolution. Cell stimulation enhanced SRF activity by increasing the number of long chromatin-associated SRF molecules in an oscillating pattern. Further, stimulation enhanced the SRF chromatin residence time, and SRF binding events segregated into three distinct residence time regimes (short, intermediate, and long bound). In summary, our single-molecule imaging study reveals highly dynamic and diverse SRF interactions with DNA. Thus, cell stimulation regulates TF activity by several interconnected mechanisms including nucleus−cytoplasm shuttling, TF phosphorylation, cofactor recruitment, and extension of chromatin residence time and enhancing chromatin-bound TF numbers.
