DISCOLORATION OF NANOHYBRID AND NANOFILLER RESIN COMPOSITES AFTER EXPOSURE TO TURMERIC

Background: Recently, the demand of aesthetic restorative has greatly increased and enchourages the development of composite resin material. The latest technology of composite is nanohybrid and nanofiller composites. However, color stability of nanohybrid and nanofiller resin composites can be influence by intrinscic and (or) extrinsic factor. Intrinsic factor depends on the composition on the resin composite and extrinsic factor such as colored food and beverages. Turmeric as a food ingredients, that is often consumed by Indonesians can cause discoloration in composites, because it contains the active pigment curcuminoid. The discoloration of nanohybrid and nanofilles composites can caused by the process of water sorbstion and curcumin particles. Purpose: Explain the discoloration of nanohybrid and nanofiller resin composites after exposure to turmeric and the factor that influence. Review(s): The reaction between the curcumin contained in turmeric and nanohybrid as well as nanofiller composites can cause discoloration in both composites. One of the reasons behind the discoloration on composite resin is that the composite resin can absorb water and its substances are carried by the water. Discoloration of composites was influence by the concentration of turmeric solution, pH of the solution, finishing and polishing process, temperature, time of exposure, composition of filler and matrix. Conclusion: Turmeric as an extrinsic factor can cause color changes in nanohybrid and nanofiller composites (ΔE>3,3), where the level of color change can be obtained by intrinsic factors, such as composition of filler and matrix, and other extrinsic factors.

Analisis Motivasi Mahasiswa dalam Menempuh Kuliah pada Program Studi Manajemen Jenjang Strata-1 Sekolah Tinggi Ilmu Ekonomi Jambi

The main purpose of this research paper is to analyze the motivation of students in science education at Sekolah Tinggi Ilmu Ekonomi (STIE) Jambi in the odd semester with Academic Year 2020/2021. Survey research method using motivation closed questionnaire is used in this research. The population in this research are Students at the Management Study Program of academic year 2020/2021 in the odd semester, with samples of 100 Respondents. Analysis of research data using descriptive statistical analysis. These conclusion reveals that the extrinsic factor is dominate students motivation in pursuing the Management Study Program at STIE Jambi were 60,47%, while intrinsic factors were 39,53%. It’s the meaning that the extrinsic factors were 20,94% greater than the intrinsic factors.

Electrospinning: A promising technique for drug delivery systems

In the last years, electrospinning has become a technique of intense research to design and fabricate drug delivery systems (DDS), during this time a vast variety of DDS with mainly electrospun polymers and many different active ingredient(s) have been developed, many intrinsic and extrinsic factor have influence in the final system, there are those that can be attributed to the equipment set up and that to the physical-chemical properties of the used materials in the fabrication of DDS. After all, this intense research has generated a great amount of DDS loaded with one or more drugs. In this manuscript a review with the highlights of different kind of systems for drug delivery systems is presented, it includes the basic concepts of electrospinning, types of equipment set up, polymer/drug systems, limitations and challenges that need to be overcome for clinical applications.

Diagnostic Clue in a Neonate with Amniotic Band Sequence

Amniotic band syndrome (ABS) is a set of congenital malformations that mainly affect the limbs and more rarely the skull, face, chest, and abdomen. Two main hypotheses have been proposed to explain the nature of the disorder: an intrinsic and extrinsic factor. We report a newborn with ABS presenting with several malformations involving both hands and foot. In this case, the malformative event localized at the hands and right foot without involvement of any other internal organs and is asymmetric which leads us to suppose the extrinsic factor as cause of the ABS.

FAKTOR-FAKTIR YANG MEMPENGARUHI MOTIVASI SISWA SEKOLAH DASAR DALAM MENGIKUTI AKTIVITAS PRAMUKA PENGGALANG

This article was written based on qualitative research on students' motivation in participating in Boy Scout exercises. This article aims to describe the motivation of students in one integrated Islamic elementary school in Pekanbaru to take part in a scout-raising(penggalang) exercise. The sample in this study were 17 students raising, consisting of 9 men and 8 women. Data was collected using direct interviews with students and documentation in the form of program documents, reports and photos of activities. Held in the even semester term 2019/2020. From the results of data processing it was found that in following the Scouting activities students were influenced by several intrinsic and extrinsic factors. Intrinsic factors are first the need to be accepted and respected, secondly the hope to develop abilities, and thirdly the interests associated with socialization. Next extrinsic factor is the first family, because of the family background of a member of the scout, the second environment, the environment of friendship students become one of the students' encouragement to participate in scout activities, Thirdly the rewards, these rewards are also a bit of one of the reasons children participate in scouting activities , because of the award given by the school to students who excel in scouting activities, triggers the emergence of student motivation. With these results, it is hoped that advanced scout activities will need to consider these three factors.

VALIDITY OF PRE-ISLAMIC ARABIC LITERATURE AS A SOURCE OF AUTHENTICATION OF HADIS

The focus of this paper is the authenticity of the hadith, because in addition to the problem of the method used, it is also a matter of sources that are problematic. One source that is often used is literature, especially pre-Islamic Arabic literature (jahiliyah). The relevance of literature in authenticating hadith gives rise to a question, the extent to which the validity of pre-Islamic Arabic Literature can be used as evidence and what are the requirements that must be met when the study of the authenticity of hadith uses pre-Islamic Literature as one of the proofs. Using a Using a descriptive analytic method with a historical approach, this paper concludes that pre-Islamic Arabic literature when used as a source of authenticity of the hadith then the task of research is to reduce the difference in question. The reduction is intended so that the legality of literature as a source of hadith authentication can be accepted. This reduction includes: (1) authorship. Just as the news attributed to the Prophet must be proven to have its source in the Prophet, pre-Islamic Arabic Literature must also be proven to come from pre-Islamic Arabic writers, (2) narration. Pre-Islamic Arabic literature must also be tested extrinsically as an extrinsic factor test on the Hadith of the Prophet, (3) context. Literature was born not in an empty space so that the content of pre-Islamic Arabic literature must also reflect the life of the Arab Nation in pre-Islamic times. Therefore, when the reduction has not yet been carried out, in the context of the accuracy of the study of the authenticity of the hadith it cannot be accepted.

Muscle-derived Myoglianin regulates Drosophila imaginal disc growth

Organ growth and size are finely tuned by intrinsic and extrinsic signaling molecules. In Drosophila, the BMP family member Dpp is produced in a limited set of imaginal disc cells and functions as a classic morphogen to regulate pattern and growth by diffusing throughout imaginal discs. However, the role of TGFβ/Activin-like ligands in disc growth control remains ill-defined. Here, we demonstrate that Myoglianin (Myo), an Activin family member, and a close homolog of mammalian Myostatin (Mstn), is a muscle-derived extrinsic factor that uses canonical dSmad2-mediated signaling to regulate wing size. We propose that Myo is a myokine that helps mediate an allometric relationship between muscles and their associated appendages.
