A MATHEMATICAL MODEL OF PROFIT-LOSS SHARING SCHEME OF SMALL INVESTMENT FOR TRADITIONAL MARKET TRADERS USING THE SEMI-FUZZY LOGIC APPROACH
Authors: Sumarti Novriana , Marendri Adythia Dean 
Published: March 2018

A mathematical model of micro-finance investment using profit-loss sharing scheme are made and implemented to simulated data. Here profits from the venture will be shared in a portion between the investor and the entity running the business. The scheme can be classified as Musharaka type of investment in Sharia economy. The proposed model is theoretically implemented with data from small-scale traders at a local traditional market who have small turnover. They are common target of usurers who lend money with high interest rate and penalties. If the traders are in unfortunate conditions, they are potentially in poorer condition than before committing themselves to the usurer. In the conventional practices of the profit sharing scheme, the investor will get a fixed portion of the trader’s income, which is applied for all kind of small-scale traders. If the traders are diligent and hard worker and have very high turnover, then the investor will gain much more profit whether the contributed capital is small or large. In this paper, the scheme is implemented using Semi-Fuzzy Logic Approach so that the profit-loss sharing scheme can achieve its intended goal, which is to make a profitable investment not only for the investor but also for traders. The approach is not fully using Fuzzy Logic because some variables are still in crisp numbers and the optimization problem is regular in the form of crisp numbers. Based on the existing data, the results show that the optimal profit share is depended on the income of the traders. The higher the income coming from the venture, the lesser the profit share for the investor which is reasonable with the fixed initial contributed capital.

AN EXPLORATION OF CUSTOMERS’ SWITCHING BEHAVIOR IN ISLAMIC BANKING INDUSTRY
Authors: Rama Ali 
Published: March 2018

The existence of the switching behavior among Islamic bank customers may affect to the survival of the Islamic banks of the country. Switching behavior is mostly as an outcome of the negative service experience that may be related to several factors. The purpose of the study is to provide an insight of the drivers that lead to a bank customer switching behavior from one Islamic bank to another bank. The study employed survey method through questionnaire instrument and distributed to Islamic banking customers in several areas of Banten Province, Indonesia. The result of statistical analysis shows that customer satisfaction, service quality, shariah compliance, prices and involuntary switching have their significant effect on customers’ switching behavior in the Islamic banks. However, service failure and advertisement are not statistically significant in driving bank switching. Therefore, the Islamic bank manager should shape their business model around customers’ needs and focuses operational improvements on customers’ most valued interactions.

Nutrient Release from Living and Terminated Cover Crops Under Variable Freeze–Thaw Cycles
Authors: Cober James R. , Macrae Merrin L. , Van Eerd Laura L. 
Published: March 2018

Core Ideas
Light frosts did not increase phosphorus release from cover crops.Heavy frosts released more water‐extractable phosphorus than light frosts.Herbicide induced termination increased phosphorus and ammonium losses.Frost tolerant species released less phosphorus than frost‐intolerant species.Cover crops remain a suitable management practice in temperate regions.
Cover crops (CC) are planted into fields during the non‐growing season as a best management practice (BMP) for agronomic and environmental benefits. However, freeze–thaw cycles (FTC) may increase the availability of water extractable P (WEP) from damaged plant tissues, leading some to question their efficacy as a nutrient BMP due to their potential to release P during snowmelt. The objectives of this study were to experimentally determine the influence of: (1) FTC magnitude (4°C, −4 to 4°C, –18 to 4°C, and –18 to 10°C), (2) CC species [cereal rye (Secale cereale L.), oilseed radish (Raphanus sativus L. var. oleoferus Metzg Stokes), red clover (Trifolium pratense L.), oat (Avena sativa L.), and hairy vetch (Vicia villosa Roth)], and (3) termination using herbicide on the magnitude of WEP, NH4+, and NO3− release. Shoot tissue clippings underwent five FTC followed by extraction. Large magnitude FTC from –18 to 4 and –18 to 10°C (heavy frost) elevated WEP release, whereas the −4 to 4°C (light frost) treatment did not. Responses varied with plant type, where frost‐intolerant species released more WEP than frost‐tolerant species. In contrast, NH4+, and NO3− release did not increase following FTC. Termination elevated WEP and NH4+ release across all temperature treatments. The use of CC as a nutrient BMP should be used with caution in some regions, but in areas with mild winter climates, growing frost tolerant species without termination may reduce the risk of P leaching from vegetation in winter and early spring.

Published: March 2018

Introduction:Introduction: Protease Inhibitors (PIs) constitute a group of proteins widely distributed among all organisms and their main function includes their ability to inhibit the proteolytic activity. PIs represent an important role in the regulation of various cellular physiological and biological processes, including cell cycle, cell death, differentiation and immune response.Material and Methods:Hence, in our search for novel anticancer compounds, we isolated microorganisms from various environmental sources and screened them for the production of protease inhibitors. Promising isolates were further checked for their protease inhibitory activity by their ability to inhibit the activity of trypsin and chymotrypsin, which were measured spectrophotometrically.Results:The isolate identified as Bacillus endophyticus JUPR15 was found to be promising with higher inhibitory activity than the other isolates. The inhibitor was purified by cold acetone precipitation and column chromatography and further subjected to characterization studies by performing 12 % SDS-PAGE to determine the molecular weight and gelatin-PAGE assay to confirm its inhibitory activity.Conclusion:The isolate exhibited promising anticancer activity on in-vitro Hela and HepG2 cancer cell lines, showing its application potentials.

Authors: Abo-Shady Atef M. , Zalat Abdelfattah A. , Al-Ashkar Emad A. , Ghobara Mohamed M. 
Published: March 2018

Background:Diatoms are a large unique group of unicellular microalgae with a significant ornamented cell wall made of hydrated silica, which is called "frustule". Their ornamented siliceous shells are usually composed of multi-layer structures with multi-scale porosity, which can be used as a promising source to obtain hierarchical macro and mesoporous silica microparticles. The present study is one step forward through a long road seeking for green nanofabrication techniques of such porous materials that will be economically more efficient with large design flexibility.Materials and Methods:For seeking different porosity scales, architectures, and distribution patterns, a total of 237 diatom species and varieties belonging to 68 genera were identified from 59 samples, which were collected from different Egyptian habitats and environments. Of these eight species were selected to study their frustules' ultra-structures in details, including; Aulacoseira granulata (Ehrenberg) Simonsen, Actinocyclus octonarius Ehrenberg, Cyclotella meneghiniana Kützing, Pleurosira laevis (Ehrenberg) Compére, Synedra ulna (Nitzsch) Ehrenberg, Achnanthes brevipes Agardh, Nitzschia amphibia Grunow and Nitzschia palea (Kützing) W. Smith. Nitzschia palea (Kützing) W. Smith was also isolated and cultivated.Results:The ultrastructure and porosity of all studied species had been revealed. The porosity scale was ranged from 5 to 500 nm in diameter.Conclusion:The obtained results showed the potential of diatom frustules in nanotechnology as a source of natural silica microparticles with macro and mesoporous structures could be of a large interest for applications including ultra, micro and nanofiltration, drug delivery systems, optoelectronics, or other novel nanotechnology applications.
On Certain Counting Polynomial of Titanium Dioxide Nanotubes
Authors: Prabhu S. , Arulperumjothi M. , Murugan G. , Dhinesh V.M. , Kumar J.P. 
Published: March 2018

Background:
In 1936, Polya introduced the concept of a counting polynomial in chemistry.
However, the subject established little attention from chemists for some decades even though the spectra
of the characteristic polynomial of graphs were considered extensively by numerical means in order
to obtain the molecular orbitals of unsaturated hydrocarbons. Counting polynomial is a sequence representation
of a topological stuff so that the exponents precise the magnitude of its partitions while the coefficients
are correlated to the occurrence of these partitions. Counting polynomials play a vital role in
topological description of bipartite structures as well as counts of equidistant and non-equidistant edges
in graphs. Omega, Sadhana, PI polynomials are wide examples of counting polynomials.

Methods:
Mathematical chemistry is a division of abstract chemistry in which we debate and forecast
the chemical structure by using mathematical models. Chemical graph theory is a subdivision of mathematical
chemistry in which the structure of a chemical compound can be embodied by a labelled graph
whose vertices are atoms and edges are covalent bonds between the atoms. We use graph theoretic
technique in finding the counting polynomials of TiO2 nanotubes.

:
Let ! be the molecular graph of TiO2. Then (!, !) = !!10!!+8!−2!−2 + (2! +1) !10!!+8!−2! + 2(! +
1)10!!+8!−2

Results:
In this paper, the omega, Sadhana and PI counting polynomials are studied. These polynomials
are useful in determining the omega, Sadhana and PI topological indices which play an important role in
studies of Quantitative structure-activity relationship (QSAR) and Quantitative structure-property relationship
(QSPR) which are used to predict the biological activities and properties of chemical compounds.

Conclusion:
These counting polynomials play an important role in topological description of bipartite
structures as well as counts equidistance and non-equidistance edges in graphs. Computing distancecounting
polynomial is under investigation.

Published: March 2018

The goal of the research is to gain insights into the characteristics of the items in the mathematics national examination, the attributes on which the items were formulated and the result of a conceptual error diagnosis of the mathematics materials based on the result of the junior high school mathematics national examination. This is quantitative descriptive research. The data were collected from 3,079 grade-nine students of junior high schools who took the National Examination in the academic year of 2015/2016. The sample was established randomly based on the package code of the examination which is P0C5520 with 574 students as the examinees. Documentation method was applied in collecting the data. The result of the research shows that – upon the implementation of the classical test theory – there are 16 items in ‘difficult’ category, 24 in ‘intermediate’ category, and no items in ‘easy’ category. Furthermore, upon the implementation of the item response theory, the result shows that 28 items are in ‘good’ category and 12 items are in ‘poor’ category. In addition, there are 50 attributes on which the Junior High School Mathematics National Examination test (package P0C520) is formulated. Four attributes are content attributes and the rest (46) are process skill attributes. The result of the diagnosis shows that there are 11 types of errors made by the students when trying to complete the content items. Most of the errors are conceptual errors related to the geometric materials especially in the sub-materials of polyhedron, triangles, and quadrangles.

Published: March 2018

O artigo discute a situação atual dos salários e jornadas de trabalho dos professores na rede pública esta dual paulista a fim de verificar a adequação à Lei nº 11.738, de 2008, que criou o piso salarial do magistério. Evidencia-se que o estado sistematicamente dribla a legislação federal, adequando, de forma questionável, a jornada de trabalho dos professores à lei do piso, e pagando, este ano, remuneração abaixo do estabelecido legalmente, o que amplia a desvalorização dos professores.
Revenue Recognition at TSA, Inc.—A Roller Coaster Ride
Authors: Chandra Uday , Dutta Saurav K. , Marcinko David J. 
Published: March 2018

ABSTRACT
This case chronicles revenue recognition practices at TSA, Inc. from 1997 to 2002. As growth in TSA's revenue declined, the company's revenue recognition practices became more aggressive. In 2002, TSA's incoming auditors re-evaluated its revenue recognition policies and restated its financial statements for three prior years. The case provides a real-world situation with complex contracts through which students can improve their understanding of the five-step revenue recognition process under ASC 606, which became effective in fiscal year 2018 for most public entities. Further, it is a rich setting in which to illustrate the judgment and complexity involved in revenue recognition. The case provides students with an opportunity to approach revenue recognition from different perspectives—that of corporate accountant, manager, external auditor, and investor—and is designed for use in Intermediate Accounting as well as in capstone accounting courses at both the undergraduate and graduate levels.

Published: March 2018

SUMMARY
The aim of this review was to compile recent evidence related to nanofilled resin composite materials regarding the properties and clinical performance. Special attention was given to mechanical properties, such as strength, hardness, abrasive wear, water sorption, and solubility. The clinical performance of nanocomposite materials compared with hybrid resin composites was also addressed in terms of retention and success rates, marginal adaptation, color match, and surface roughness. A search of English peer-reviewed dental literature (2003-2017) from PubMed and MEDLINE databases was conducted using the terms “nanocomposites” or “nanofilled resin composite” and “clinical evaluation.” The list was screened, and 82 papers that were relevant to the objectives of this work were included in the review. Mechanical properties of nanocomposites are generally comparable to those of hybrid composites but higher than microfilled composites. Nanocomposites presented lower abrasive wear than hybrids but higher sorption values. Their clinical performance was comparable to that of hybrid composites.
