Influence of Increasing Tungsten Concentrations and Soil Characteristics on Plant Uptake: Greenhouse Experiments with Zea mays
Authors: Petruzzelli Gianniantonio , Pedron Francesca
Published: September 2019

Tungsten is largely used in high-tech and military industries. Soils are increasingly enriched in this element, and its transfer in the food chain is an issue of great interest. This study evaluated the influence of soil characteristics on tungsten uptake by Zea mays grown on three soils, spiked with increasing tungsten concentrations. The soils, classified as Histosol, Vertisol, and Fluvisol, are characteristic of the Mediterranean area. The uptake of the element by Zea mays was strictly dependent on the soil characteristics. As the pH of soils increases, tungsten concentrations in the roots and shoots of the plants increased. Also, humic substances showed a great influence on tungsten uptake, which decreased with increasing organic matter of soils. Tungsten uptake by Zea mays can be described by a Freundlich-like equation. This soil-to-plant transfer model may be useful in promoting environmental regulations on the hazards of this element in the environment.
What Is the Real Clausius Statement of the Second Law of Thermodynamics?
Authors: Xue Ti-Wei , Guo Zeng-Yuan
Published: September 2019

In this paper, we first analyze the difference between the second law of thermodynamics and the laws in other disciplines. There are some phenomena in other disciplines similar to the Clausius Statement of the second law, but none of them has been accepted as the statement of a certain law. Clausius’ mechanical theory of heat, published in the nineteenth century, is then introduced and discussed in detail, from which it is found that Clausius himself regarded “Theorem of the equivalence of the transformation of heat to work, and the transformation of heat at a higher temperature to a lower temperature”, rather than “Heat can never pass from a colder to a warmer body without some other change”, as the statement of the second law of thermodynamics. The latter is only laid down as the fundamental principle for deriving the theorem of the equivalence of transformations. Finally, based on the theorem of the equivalence of transformations and the average temperature method, a general quantitative relation among the heat, the work, and the temperatures is obtained for arbitrary cycles, which is thus recommended as an alternative mathematic expression of the second law. Hence, the theorem of the equivalence of transformations is the real Clausius Statement of the second law of thermodynamics.
Control and Entropy Analysis of Corner Flow Separation in a Compressor Cascade Using Streamwise Grooves
Authors: Yi Weilin , Ji Lucheng
Published: September 2019

Flow separation, which often occurs at the junction of blades and endwalls and seriously limits the aerodynamic performance of turbomachinery, is caused mainly by the boundary layer mixing on the blades and endwall surfaces and the transverse secondary flow. Focusing on a linear diffusion cascade with 42° turning angle, the transverse secondary flow is found to be the dominant factor for flow separation, based on detailed analysis. Therefore, controlling the secondary flow to reduce the flow separation is very important. Based on the investigations, the flow separation can be controlled by cutting off the secondary flow. Therefore, nine kinds of streamwise grooves were designed and analyzed herein. Grooves at the endwall substantially inhibited the transverse secondary flow, but the flow structure varied over different spans. An optimum combination of groove width and height was identified, with the height being more important. A detailed flow analysis of the best scheme (with a smaller width and moderate height) was conducted. The loss reduction mechanism was obtained by 3D flow field and entropy analysis. This configuration can reduce the corner zone separation effect, energy loss coefficient, and flow loss.
Parallel Implementation of Modeling of Fractional-Order State-Space Systems Using the Fixed-Step Euler Method
Authors: Stanisławski Rafał , Kozioł Kamil
Published: September 2019

This paper presents new results in implementation of parallel computing in modeling of fractional-order state-space systems. The methods considered in the paper are based on the Euler fixed-step discretization scheme and the Grünwald-Letnikov definition of the fractional-order derivative. Two different parallelization approaches for modeling of fractional-order state-space systems are proposed, which are implemented both in Central Processing Unit (CPU)- and Graphical Processing Unit (GPU)-based hardware environments. Simulation examples show high efficiency of the introduced parallelization schemes. Execution times of the introduced methodology are significantly lower than for the classical, commonly used simulation environment.
AKL-ABC: An Automatic Approximate Bayesian Computation Approach Based on Kernel Learning
Authors: González-Vanegas Wilson , Álvarez-Meza Andrés , Hernández-Muriel José , Orozco-Gutiérrez Álvaro
Published: September 2019

Bayesian statistical inference under unknown or hard to asses likelihood functions is a very challenging task. Currently, approximate Bayesian computation (ABC) techniques have emerged as a widely used set of likelihood-free methods. A vast number of ABC-based approaches have appeared in the literature; however, they all share a hard dependence on free parameters selection, demanding expensive tuning procedures. In this paper, we introduce an automatic kernel learning-based ABC approach, termed AKL-ABC, to automatically compute posterior estimations from a weighting-based inference. To reach this goal, we propose a kernel learning stage to code similarities between simulation and parameter spaces using a centered kernel alignment (CKA) that is automated via an Information theoretic learning approach. Besides, a local neighborhood selection (LNS) algorithm is used to highlight local dependencies over simulations relying on graph theory. Attained results on synthetic and real-world datasets show our approach is a quite competitive method compared to other non-automatic state-of-the-art ABC techniques.
A Note on Minimal Translation Graphs in Euclidean Space

Published: September 2019

In this note, we give a characterization of a class of minimal translation graphs generated by planar curves. Precisely, we prove that a hypersurface that can be written as the sum of n planar curves is either a hyperplane or a cylinder on the generalized Scherk surface. This result can be considered as a generalization of the results on minimal translation hypersurfaces due to Dillen–Verstraelen–Zafindratafa in 1991 and minimal translation surfaces due to Liu–Yu in 2013.
Relationship between Muscle Mass/Strength and Hepatic Fat Content in Post-Menopausal Women
Authors: Zhang Yajie , Lu Dajiang , Wang Renwei , Fu Weijie , Zhang Shengnian
Published: September 2019

Background and Objectives: Recent studies have shown that low skeletal muscle mass can contribute to non-alcoholic fatty liver disease through insulin resistance. However, the association between muscle mass/strength and hepatic fat content remains unclear in postmenopausal women. Methods: In this study, we assessed the associations between muscle mass/strength and various severities of non-alcoholic fatty liver disease. Using single-voxel proton magnetic resonance spectroscopy, 96 postmenopausal women between the ages of 50 and 65 were divided into four groups (G0–G3) by hepatic fat content: G0 (hepatic fat content <5%, n = 20), G1 (5% ≤ hepatic fat content < 10%, n = 27), G2 (10% ≤ hepatic fat content < 25%, n = 31), and G3 (hepatic fat content ≥25%, n = 18). Muscle mass indexes were estimated as skeletal muscle index (SMI)% (total lean mass/weight × 100) and appendicular skeletal muscular mass index (ASM)% (appendicular lean mass/weight × 100) by dual energy X-ray absorptiometry. Maximal isometric voluntary contraction of the handgrip, elbow flexors, and knee extensors was measured using an adjustable dynamometer chair. Fasting plasma glucose, insulin, and follicle-stimulating hormones were assessed in venous blood samples. Results: The results showed negative correlations between hepatic fat content and SMI% (r = −0.42, p < 0.001), ASM% (r = −0.29, p = 0.005), maximal voluntary force of grip (r = −0.22, p = 0.037), and knee extensors (r = −0.22, p = 0.032). Conclusions: These significant correlations almost remained unchanged even after controlling for insulin resistance. In conclusion, negative correlations exist between muscle mass/strength and the progressed severity of non-alcoholic fatty liver disease among post-menopausal women, and the correlations are independent of insulin resistance.
Semi-Continuous Equal-Channel Angular Extrusion and Rolling of AA5083 and AZ31 Alloys
Authors: Segal Vladimir , Reznikov Svetlana V. , Murching Nagendra , Hammond Vincent H. , Kecskes Laszlo J.
Published: September 2019

This paper describes a new modification of equal-channel angular extrusion for the “pass-by-pass” semi-continuous (sc-ECAE) processing of lightweight alloys. Sc-ECAE leads to a multifold increase in productivity and decrease in costs, providing a technical basis for the commercialization of severe plastic deformation (SPD) on a large scale with massive volume production. The evolution of the structure and properties are analyzed for an aluminum alloy (AA) 5083 and a magnesium alloy AZ31 as model materials representing, respectively, the structural refinement under severe plastic deformation (SPD) via strain-induced formation of new grain boundaries and via dynamic recrystallization. For the first alloy, the microstructure after sc-ECAE is formed via ultrafine sub-grains, which are further transformed into sub-micrometer grains during post-ECAE rolling. The preliminary solution treatment of AA5083 is an important stabilizing factor for the achievement of high mechanical properties. For the second alloy, optimized sc-ECAE results in a remarkable structural refinement, and a good balance of properties is obtained with a low number of passes. However, additional rolling in the latter case leads to a degradation of the structure and properties.
High Surface Proton Conduction in Nanostructured ZIF-8
Authors: Muñoz-Gil Daniel , Figueiredo Filipe M. L.
Published: September 2019

The zeolitic imidazolate framework-8 (ZIF-8) combines a significantly high microporosity with an excellent thermal, chemical, and hydrothermal stability. Here, we demonstrated that ZIF-8 can display significant levels of protonic conductivity through a water-mediated surface transport mechanism associated to the presence of di-coordinated Zn ions revealed by X-ray photoelectron spectroscopy. A set of powders with particle sizes from 2.8 µm down to 80 nm studied by dynamic water vapour sorption analysis was used to demonstrate that water adsorbs predominantly in the micropore cavities of microcrystalline ZIF-8, whereas adsorption on the external surface becomes the dominant contribution for the nanostructured material. Impedance spectroscopy in turn revealed that the protonic conductivity of the nanocrystalline ZIF-8 was two orders of magnitude higher than that of the micron-sized powders, reaching approximately 0.5 mS·cm−1 at 94 °C and 98% relative humidity. Simple relations were derived in order to estimate the potential gains in water uptake and conductivity as a function of the particle size. This new strategy combining particle nanostructuring with surface defects, demonstrated here for one of the most know metal organic framework, is of general application to potentially boost the conductivity of other materials avoiding chemical functionalization strategies that in most if not all cases compromise their chemical stability, particularly under high humidity and high temperature conditions.
A VCO-Based CMOS Readout Circuit for Capacitive MEMS Microphones

Published: September 2019

Microelectromechanical systems (MEMS) microphone sensors have significantly improved in the past years, while the readout electronic is mainly implemented using switched-capacitor technology. The development of new battery powered “always-on” applications increasingly requires a low power consumption. In this paper, we show a new readout circuit approach which is based on a mostly digital Sigma Delta ( Σ Δ ) analog-to-digital converter (ADC). The operating principle of the readout circuit consists of coupling the MEMS sensor to an impedance converter that modulates the frequency of a stacked-ring oscillator—a new voltage-controlled oscillator (VCO) circuit featuring a good trade-off between phase noise and power consumption. The frequency coded signal is then sampled and converted into a noise-shaped digital sequence by a time-to-digital converter (TDC). A time-efficient design methodology has been used to optimize the sensitivity of the oscillator combined with the phase noise induced by 1 / f and thermal noise. The circuit has been prototyped in a 130 nm CMOS process and directly bonded to a standard MEMS microphone. The proposed VCO-based analog-to-digital converter (VCO-ADC) has been characterized electrically and acoustically. The peak signal-to-noise and distortion ratio (SNDR) obtained from measurements is 77.9 dB-A and the dynamic range (DR) is 100 dB-A. The current consumption is 750 μ A at 1.8 V and the effective area is 0.12 mm 2 . This new readout circuit may represent an enabling advance for low-cost digital MEMS microphones.

Published: September 2019

Prefabrication (PC) projects have many advantages, such as cost and energy savings and waste reduction. However, some problems still exist that hamper the development of prefabrication projects. To improve PC project performance and advance innovation in construction, this study introduces an innovative method that incorporates Radio Frequency Identification (RFID) and Long Range (LoRa) technologies, sensor networks, the BIM model and cloud computing to automatically collect, analyze and display real-time information about PC components. It can locate PC components on a construction site and monitor their structural performance during the installation process. RFID technology and strain sensors were used to collect the required data on a construction site. All the data was transmitted to a server using LoRa technology. Then, the cloud-based Building Information Modelling (BIM) model of the project was developed to store and vividly present project information and real-time onsite data. Moreover, the cloud-based BIM model enables project team members to access the project information from anywhere by using mobile devices. The proposed system was tested on a real PC project to validate its effectiveness. The results indicate that the sensor network can provide reliable data via LoRa technology, and a PC component can be accurately located on site. Also, the monitoring data of structural performance for the PC component during the installation process is acceptable. The proposed method using innovative technologies can improve PC project performance and help industry professionals by providing sufficient required information.

Published: September 2019

A mobile system that can detect viruses in real time is urgently needed, due to the combination of virus emergence and evolution with increasing global travel and transport. A biosensor called PAMONO (for Plasmon Assisted Microscopy of Nano-sized Objects) represents a viable technology for mobile real-time detection of viruses and virus-like particles. It could be used for fast and reliable diagnoses in hospitals, airports, the open air, or other settings. For analysis of the images provided by the sensor, state-of-the-art methods based on convolutional neural networks (CNNs) can achieve high accuracy. However, such computationally intensive methods may not be suitable on most mobile systems. In this work, we propose nanoparticle classification approaches based on frequency domain analysis, which are less resource-intensive. We observe that on average the classification takes 29 μ s per image for the Fourier features and 17 μ s for the Haar wavelet features. Although the CNN-based method scores 1–2.5 percentage points higher in classification accuracy, it takes 3370 μ s per image on the same platform. With these results, we identify and explore the trade-off between resource efficiency and classification performance for nanoparticle classification of images provided by the PAMONO sensor.
Ensembles of Deep Learning Models and Transfer Learning for Ear Recognition
Authors: Alshazly Hammam , Linse Christoph , Barth Erhardt , Martinetz Thomas
Published: September 2019

The recognition performance of visual recognition systems is highly dependent on extracting and representing the discriminative characteristics of image data. Convolutional neural networks (CNNs) have shown unprecedented success in a variety of visual recognition tasks due to their capability to provide in-depth representations exploiting visual image features of appearance, color, and texture. This paper presents a novel system for ear recognition based on ensembles of deep CNN-based models and more specifically the Visual Geometry Group (VGG)-like network architectures for extracting discriminative deep features from ear images. We began by training different networks of increasing depth on ear images with random weight initialization. Then, we examined pretrained models as feature extractors as well as fine-tuning them on ear images. After that, we built ensembles of the best models to further improve the recognition performance. We evaluated the proposed ensembles through identification experiments using ear images acquired under controlled and uncontrolled conditions from mathematical analysis of images (AMI), AMI cropped (AMIC) (introduced here), and West Pomeranian University of Technology (WPUT) ear datasets. The experimental results indicate that our ensembles of models yield the best performance with significant improvements over the recently published results. Moreover, we provide visual explanations of the learned features by highlighting the relevant image regions utilized by the models for making decisions or predictions.

Published: September 2019

In the present study the authors investigated the effect of sunburn injury on fruit quality parameters (cover colour, depth of tissue damage, fruit flesh firmness, dry matter content) of apple.The symptoms of sunburn injury appeared as concentric rings, differing in colour from each other and the cover colour. This can be connected with the ratio of the injury. The authors observed the following colours on the fruit surface (from the epicentre of spots on the surface of the fruit) dark brown (strongly damaged), light brown (moderately damaged), pale red transition (weakly damaged), red surface cover colour (not damaged).Sunburn of apple fruits is a surface injury caused by solar radiation, heat and low relative humidity. In the initial phase, a light corky layer, golden or bronze discolouration and injuries of the epidermal tissue appear on the surface exposed to radiation. Thus, it detracts from the fruit’s appearance, but in most of the cases it would not cause serious damages in the epidermal tissue. The depth of tissue damage is not considerable, its values are between 1.5-2.0 mm in general. It is commonly known, that tissue structure of the apple fruit is not homogeneous. Accordingly, the degree of injury shows some differences under the different parts of the fruit surface.On the basis of the flesh firmness studies, it can be stated that the flesh firmness of the damaged parts increases due to the sunburn effect. This is due to the fact that the damaged plant cells die, the water content of the tissue decreases and it hardens. However, due to this reduction in the water content the dry matter content will increase.
The father of the term ‘biotechnology’ was Hungarian: The forgotten works of Károly Ereky
Authors: Gábor Miklós Gábor , Kralovánszky Ubul Pál
Published: September 2019

In the Nature, Robert Bud gave an account of the fact that the generator of the concept "biotechnology" was the Hungarian Karl Ereky who, in his book published in Berlin in 1919 entitled "Biotechnologie der Fleisch-, Fett- und Milcherzeugung im landwirtschaftlichen Grossbetriebe" ("Biotechnology of Meat, Fat and Milk Production in a Large-Scale Agricultural Farm"), disclosed his observations and new views in that regard. Later on, Ereky's two essays, published in German language again, and other contemporary German sources have been processed which have confirmed the assumption whereas – in scientific terms – the further first applications of the expression "biotechnology" can be attributed to Ereky's works. Recently, we have explored and found biographical sources and documents which had been published by Ereky, which, however, have already been forgotten, by dint of which the story of origin of the first concept "biotechnology" can as well be clarified in a factual manner.

El lupus eritematoso sistémico (LES) es una enfermedad autoinmune multisistémica, con exacerbaciones y remisiones o con actividad perenne, que conlleva al desarrollo de daño orgánico. Debido a las múltiples formas de presentación y la variedad de órganos que pueden estar comprometidos, el diagnóstico del LES siempre ha sido un reto. A continuación presentamos el caso de una paciente con diagnóstico de LES, en quien su principal manifestación de la enfermedad fue hematológica y los anticuerpos antinucleares (ANA) son negativos y los anticuerpos anti-Ro son positivos. Los ANA han sido utilizado como marcadores de LES y hacen parte de los criterios de clasificación propuestos por el American College of Rheumatology (ACR) para el diagnóstico de la enfermedad. Existe, sin embargo, controversia de si algunos pacientes que cumplen criterios ACR, pero con ANA negativos, si puedan ser rotulados como LES. Existen pocos reportes de caso al respecto

he current research aims to identify the happiness of kindergarten teachers. The sample consisted of (100) teachers and (5) teachers from each kindergarten. Thus, the sample reached (100) teachers distributed over (20) kindergartens from the third Karkh Education Directorate for the academic year 2018/2019. And was based on the measure of happiness prepared by (Abdul, 2012) for the Iraqi environment. (34). To analyze the results, we used the Pearson correlation coefficient to derive stability through the retest method, and the meta-test for one sample to test the importance of differences between the average responses of sample members and the theoretical average for measuring happiness. The results of the study: Riyadh teachers got high grades on the happiness scale, as the results showed that the arithmetic mean is higher than the mean.
Perkembangan Terapi Sel Punca (Stem Cell) Pada Penyakit Jantung: Masa Kini dan Masa Depan
Authors: Alwi Idrus
Published: September 2019

Penelitian terapi sel punca di dunia telah berkembang dengan pesat dalam beberapa dasa warsa terakhir, khususnya pada penyakit jantung seperti infark miokard akut, penyakit jantung koroner tahap akhir (PJTA) dan kardiomiopati. Di masa mendatang terapi sel punca dianggap sebagai batas akhir (final frontier) pengobatan berbagai penyakit. Oleh karena itu pengembangan terapi sel punca diharapkan dapat menjawab berbagai tantangan dalam tatalaksana berbagai penyakit secara mendasar. Indonesia merupakan salah satu pelopor terapi sel punca pada infark miokard akut di Asia Tenggara dan merupakan salah satu negara pertama di Asia selain Hongkong yang menggunakan alat NOGA untuk pemetaan (mapping) dan injeksi sel punca pada otot jantung melalui kateterisasi pada PJTA.

Sel punca termasuk embryonic stem cells (ESC), cardiac stem cells (CSCs) dan induced pluripotent stem cells (iPSs) dapat mengalami diferensiasi menjadi kardiomiosit dan dapat mengembalikan fungsi kontraksi jantung. Sel tersebut juga dapat berdiferensiasi menjadi sel endotel, memicu pembentukan pembuluh darah baru (angiogenesis), mengembalikan sebagian sel otot jantung yang rusak menjadi tetap hidup, dan menghambat perluasan jaringan parut. Mekanisme lain terapi sel punca pada jantung yang saat ini banyak dianut adalah melalui efek parakrin. Terdapat beberapa metoda pemberian sel punca pada jantung yaitu intrakoroner, epikardial dan intravena.

Penelitian di bidang kedokteran kardiovaskular regeneratif mengenai terapi sel punca akan terus berkembang di masa depan, termasuk mengenai jenis sel dan teknik terbaik pemberian sel punca.
Tingkat Pengetahuan Pada Mahasiwa Tingkat Akhir FK Undip Tentang Partograf
Authors: Anggoro Gandita , Dewatingrum Julian , Setiawati Amalia
Published: September 2019

Latar belakang : Partograf sebagai alat untuk memantau kemajuan persalinan, akan membantu mendeteksi persalinan abnormal, mencegah partus lama dan partus macet. Pengetahuan partograf harus dimiliki setiap tenaga penolong kesehatan, termasuk dokter. Penilaian pengetahuan partograf perlu dilakukan untuk mengetahui sejauh mana kesiapan mahasiswa kedokteran dalam menangani suatu persalinan, dengan menggunakan partograf. Penilaian tersebut ditujukan terutama pada mahasiswa kedokteran tingkat akhir, sehingga bila didapati hasil yang kurang memuaskan, dapat dilakukan intervensi sebelum mereka lulus menjadi dokter umum.

Metode : Penelitian observasional ini dilakukan dengan pendekatan potong lintang (cross sectional) yang telah dilakukan pada Juni-Juli 2011 pada Mahasiswa Fakultas Kedokteran Universitas Diponegoro yang akan lulus menjadi dokter pada tahun 2011, sebelum mengikuti kepaniteraan komprehensif. Pengambilan sampel dilakukan dengan metode purposive random sampling. Sebanyak 97 data responden memenuhi syarat kriteria. Data yang didapat diverifikasi dengan data yang berasal dari bagian akademik FK UNDIP Semarang. Analisis data berupa analisis deskriptif, dengan penyajian data dalam bentuk tabel, grafik dan presentase tingkat pengetahuan.

Hasil : Pengetahuan mahasiswa kedokteran tingkat akhir mempunyai rata-rata skor pengetahuan 15,74 (±2,23) dari total 20 pertanyaan, dengan presentase pengetahuan partograf adalah 78,7%. Hanya 17 (17,5%) mahasiswa yang dapat menulis dan menerapkan pengetahuan tersebut dengan benar kedalam simulasi kasus pengisian partograf.

Simpulan : Pengetahuan pada mahasiswa kedokteran tingkat akhir tentang partograf sudah baik. Namun masih ada beberapa poin pengetahuan yang belum dipahami oleh mahasiswa. Pengetahuan dalam pengaplikasian partograf ternyata masih kurang.

Kata kunci : partograf, pengetahuan, mahasiswa kedokteran, dokter umum
Gangguna Tidur Pada Anak Palsi Serebral
Authors: Selina Hendriani , Priambodo Winres , Sakundarno M
Published: September 2019

Latar belakang : Gangguan tidur bisa terjadi pada 25% anak normal. Tetapi pada anak anak palsi serebral (CP) yang sering mengalami keterlambatan pada berbagai aspek perkembangan, kejadian gangguan tidur lebih sering terjadi. Gangguan tidur memerlukan pemeriksaan polisomnogram yang tidak selalu dapat dilakukan di setiap pusat kesehatan karena keterbatasan sarana. Sebagai alternatif dapat dilakukan pemeriksaan dengan kuesioner Child's Sleep Habits Questionare (CSHQ) yang dikembangkan oleh Owen dari Amerika Serikat. Tujuan penelitian adalah mengetahui adanya gangguan tidur serta jenis gangguan tidur pada masing masing tipe palsi serebral.

Metode : Penelitian deskriptif dilakukan di YPAC cabang Semarang bulan Maret sampai Juli 2006 pada anak palsi serebral usia 4–12 tahun. Digunakan kuesioner CSHQ dengan cut off point > 41 sebagai tanda bahwa terdapat gangguan tidur. Kuesioner diisi oleh orang tua atau pengasuh pasien. Data dianalisis secara deskriptif. Hasil : Lima puluh anak masuk dalam kriteria inklusi, didapatkan 96% dengan gangguan tidur. Pada 41 anak palsi serebral tipe spastik didapatkan gangguan tidur dominan berupa sleep onset delay (65%), satu anak tipe diskinetik didapatkan bedtime resistance, dua anak palsi serebral tipe ataksik dengan sleep anxiety dan enam anak palsi serebral tipe campuran dengan parasomnias (83%).

Simpulan : Sebagian besar (96%) anak palsi serebral menderita gangguan tidur. Berbagai tipe palsi serebral mempunyai gangguan tidur dominan yang berbeda.
