THEORETICAL VS. EXPERIMENTAL IR FREQUENCY SHIFTS UPON Π- HYDROGEN BONDING: COMPLEXES OF SUBSTITUTED PHENOLS WITH HEXAMETHYLBENZENE
Authors: Nikolova Valia , Galabov Boris
Published: August 2017

The quality of theoretical prediction of O-H stretching frequency shifts upon π-hydrogen bonding is analyzed for series of ten complexes between monosubstituted phenols and hexamethylbenzene. Computed O-H frequencies from density functional theory computations at B3LYP/6-311++G(2df,2p) were compared with literature spectroscopic data. The results reveal that the applied theoretical method predicts with an excellent accuracy the O-H frequency shifts [Δυ(OH)] upon π-hydrogen bond formation. Comparisons with analogous theoretical and experimental data for benzene complexes with substituted phenols reveal the magnitude of the methyl groups’ hyperconjugative effects on interaction energies and frequency shifts. The induced by phenol substituents variations in bonding energies and Δυ(OH) are ra-tionalized using theoretically evaluated and experimental parameters.
River Water Quality: Who Cares, How Much and Why?
Authors: Hampson Danyel , Ferrini Silvia , Rigby Dan , Bateman Ian J.
Published: August 2017

One important motivation for the implementation of the Water Framework Directive is the creation of non-market environmental benefits such as improved ecological quality, or greater opportunities for open-access river recreation via microbial pollution remediation. Pollution sources impacting on ecological or recreational water quality can be uncorrelated but non-market benefits arising from riverine improvements are typically conflated within benefit valuation studies. Using stated preference choice experiments, we seek to disaggregate these sources of value for different river users, thereby allowing decision makers to understand the consequences of adopting alternative investment strategies. Our results suggest anglers derive greater value from improvements to the ecological quality of river water, in contrast to swimmers and rowers for whom greater value is gained from improvements to recreational quality. We also find three distinct groups of respondents: a majority preferring ecological over recreational improvements, a substantial minority holding opposing preference orderings and a small proportion expressing relatively low values for either form of river quality enhancement. As such, this research demonstrates that the non-market benefits which may accrue from different types of water quality improvements are nuanced in terms of their potential beneficiaries and, by inference, their overall value and policy implications.

Published: August 2017

This article investigated the sensitivity of capital market development to public debt in Nigeria using descriptive statistic, regression analysis, and the Engle-Granger co integration techniques for the period ranging from 1981 to 2014. The estimates from the descriptive analysis showed that both the market capitalization and public debt series were not normally distributed at 5% significance level. The ADF unit root test showed that the market capitalization and public debt series were integrated of order one (i.e., I (1)). The results from the regression model provide evidence to show that capital market development is not sensitive to domestic debt at any conventional level, but it is sensitive to external debt at 10% significance level. The estimates of the Engle-Granger co integration tests show that capital market development is not co integrated with public debt. It is recommended that capital market and debt management authorities should formulate policies will enhance linkage between the markets.

Authors: Darlis Arsyad Ramadhan
Published: August 2017

In 1992, Wornell and Oppenheim did research on a modulation which is formed by using wavelet theory. In some other studies, proved that this modulation can survive on a few channels and has reliability in some applications. Because of this modulation using the concept of fractal, then it is called as fractalmodulation. Fractal modulation is formed by inserting information signal into fractal signals that are selffractal similary. This modulation technique has the potential to replace the OFDM (Orthogonal Frequency Division Multiplexing), which is currently used on some of the latest telecommunication technologies. The purpose of this research is to implement the fractal communication system using Digital Signal Processing Starter Kit (DSK) TMS320C6713 without using AWGN and Rayleigh channel in order to obtain the ideal performance of the system. From the simulation results using MATLAB7.4. it appears that this communication system has good performance on some channels than any other communication systems. While in terms of implementation by using (DSK) via TMS320C6713 Code Composer Studio (CCS), it can be concluded that thefractal communication system has a better execution time on some tests.

Authors: Santoso Triyono Budi
Published: August 2017

Tight competition in the broadband industry has forced the provider to have a good product propotition and strategy in the market, including market segmentation and type of services delivered based on customer’s expextation and intention to buy. This research aims to make a product proposition based on two major criteries in fixed broadband service, which are speed and price of the product, by looking into the competition in existing market (competitor’s product). As many players in Indonesia have created very tight situation, the will be launched product should have an attractive matter or differentiation in order to compete and get a “buy in” of the customer. In the research, some analysis was conducted across all the propositions by spreading questionnaires to respondents in urban area especially in Jakarta and Bandung, thus the provider can create product with an appropriate specifications to answer the needs of customers on their affordable price to buy. Some close-ended questions in the questionairres were scaled and performed by basic statistical approach methods. The result shows that product with affordable price is still become the choice of respondents in each segment (low, medium and high income). Price list per speed which is fitted to any segments is also suggested in this research. The result of the research can also be used to develop the product as a differentiation to be the choices and preferencesof customers.
Boosting in English and Indonesian Research Articles: A Cross-Cultural and Cross-Disciplinary Study
Authors: Sanjaya I Nyoman Suka
Published: August 2017

Boosters, defined as linguistic devices (e.g. certainly) used by writers to indicate full commitment to the truth value of a proposition, has received little attention from applied linguists, despite their persuasive power in research writing. The present study investigated the effects of the two variables of sociocultural context and discipline on the frequency of use of boosters in research articles. A specialized corpus of 104 research articles published between 2007 and 2010 taken from applied linguistics and chemistry written in English and Indonesian by the respective native speaker scholars were quantitatively analyzed using 2 x 2 Factorial ANOVA. The results showed that there was a significant main effect of sociocultural context, F (1, 100) = 44,34, p <0,05, ŋ2 = 0,307, a significant main effect of discipline, F (1,100) = 19,16, p < 0,05, ŋ2 = 0,161, and a significant interaction between sociocultural context and discipline, F (1,100) = 6,90, p < 0,05, ŋ2 = 0,065. However, the within-sociocultural context simple effects analysis revealed that English applied linguistics and chemistry research articles were not significantly different from each other, F (1,101) = 1,07, n.s. suggesting that, discipline might not be a decisive factor that influences boosting usage in research articles. These results indicate that the two variables (sociocultural context and discipline) exerted unequal influence upon boosting practices in research articles. The differential characteristics of the two sociocultural contexts are offered as explanations to account for the differential boosting practices of English and Indonesian research articles.

The phatic function in the communication and interaction happening in the education domain could be accurately identified when the utterances were not separated from their determining pragmatic context. The context must not be limited only to contextual and social or societal perspectives, but must be defined as basic assumptions. The data of this research included various kinds of speech gathered naturally in education circles that contain phatic functions. Two methods of data gathering were employed in this study, namely listening and conversation methods. Recorded data was analyzed through the steps as follows (1) data were identified based on the discourse markers found (2) data were classified based on the phatic perception criteria; (3) data were interpreted based on the referenced theories; (4) data were described in the form of analysis result description. The research proves that phatic function in the form of small talks in the education domain cannot be separated from the context surrounding it.

Authors: Soraya Kiky
Published: August 2017

This study is aimed at finding out what appropriate methods to be usedin writing lesson seen from the students’ creativity especially for studentswho have high creativityand low creativity. This study used quasi experimental research. The population of the research was the eighth grade of a Junior High School in Wonosari in the academic year of 2013/2014. The sampling technique used was cluster random sampling. The sample in this study was 64 students covering 32 students of E as experimental class and 32 students of C as control class. The data or the students’ writing scores were analyzed in terms of their frequency distribution, normality, homogeneity, then ANOVA and Tuckey tests to test the research hypotheses. Based on the result, the research findings are: CWS is more effective than MWS in writing lesson; the high creativity students produced better writing rather than the low creativity student; and the interaction of teaching methods and the students’ creativity is existing in this writing lesson. In short, Collaborative Writing Strategy (CWS) is effective to teach writing for the eighth grade of a Junior High School in Wonosari, Gunungkidul. Then, the research result implies that it is better for the teachers to apply CWS in teaching and learning process of writing, to improve the students’ writing achievement, CWS needs to be used in the classroom activities, then future research can conduct the similar research with different sample and different students’ condition.
Intasc Standard Cores: Raising Students’ English Modality Competence
Authors: Muliani Muliani
Published: August 2017

This research aimed at raising the students’ modality competence with the implementation of a teaching model which was called as Interstate New Teachers Assessment and Support Consortium (INTASC) model that covering ten standards. It was expected that this research could give numerous contribution in teaching English, particularly in teaching English Modality where the problem found was that the students got difficulty in using modal verbs regarding both tense and aspect in which consequently would affect the communicative competence of the students. In the form of Research and Development, this research was carried by means of implementing validated instrument and 10 modules in the small and large scale assessments that involving 50 students in the small scale assessment and 80 students in the large-scale assessment. Standard 1-2 dealt with the students’ need and diversity of learning while standard 3-7 dealt with various instructions teaching the content knowledge regarding the use of English modality. Furthermore, standard 8-10 dealt with summative assessment, reflection, and professional development. Eventually, it is found that the level of learning of the students raise supported by the data that 94% of the level of learning can be achieved by the students while it was only 6% of the modality expressions cannot be used properly. It can be noted that this teaching model can assist the students in achieving the modality competence by having a very well-sequenced procedures of teaching in which this teaching model starts from considering the prior knowledge, the need, and the students’ diversity before creating further instructions regarding the content knowledge where the modality competence is the main goal to achieve.
TGF-β1 Causes EMT by Regulating N-Acetyl Glucosaminyl Transferases via Downregulation of Non Muscle Myosin II-A through JNK/P38/PI3K Pathway in Lung Cancer

Published: August 2017

Background:

Epithelial to mesenchymal transition (EMT) is a major determinant of cancer
metastasis and is closely linked with TGF-β1. Intracellular proteins, including E. Cadherin, N.
Cadherin and Vimentin are directly related to EMT that affect cell migration and adhesion; on the
other hand, non muscle myosin (NM) has a central role in cytokinesis, migration and adhesion.

Objective:

We aimed to explore the association of EMT and metastasis with TGF-β1 through regulation
of non-muscle myosin II-A (NMII-A) and its interaction with Hexosamine Biosynthesis
Pathway (HBP).

Method:

Protein expression changes were assessed by western blotting and immunofluorescent
staining while transcription level changes were assessed by qRT-PCR. EMT was assessed by phenotypic
analysis, wound healing, proliferation and transwell migration assay in vitro while in vivo
studies were conducted in BALB/c nude mice for lung orthotopic and tail vein metastasis models.

Results:

We demonstrated that regulation of JNK/ P38/PI3K by TGF-β1 led to down expression of
NMII-A which promoted EMT and lung cancer metastasis. This down expression of NMII-A conversely
upregulated the expression of Core 2 N-acetyl Glucosaminyl Transferase mucin type
(C2GnT-M) and further facilitated up-regulation and down-regulation of N-acetylglucosaminyltransferase
(GnT) -V and -III respectively; moreover, NMII-A K.D cells showed 3 times
more tendency to migrate towards brain in vivo.

Conclusion:

The study reports a novel pathway through which NMII-A negatively regulates EMT
and metastasis via up regulation of C2GnT-M, GnT-V and down expression of GnT-III. These findings
of lung cancer may further be required to study other cancer types.
Comparison of Phenolic Contents and Biological Potential of Different Polar Extracts of Micromeria graeca, from Algeria

Published: August 2017

Background: Micromeria species are rich in bioactive compounds such as phenolics which
have several medicinal properties. Different solvents are used for extraction of these substances from
natural products and solvent type has a major importance in extraction efficiency. In this context, three
solvent systems of methanol, ethanol and acetone and their mixture at 50% were used to extract the
phenolics with biological effects from Micromeria graeca (L.) Benth. ex Rchb.

Methods:

The total phenolic and flavonoid contents were determined by the Folin-Ciocalteu and aluminium
chloride methods, respectively. The antioxidant capacity of the extracts was evaluated using
three different assays. The antifungal capacity against the two strains Candida albicans and Aspergillus
niger by using the method of diffusion on disc was also carried out.

Results:

The 50% acetonic extract gave a better rate of extraction which is 14.4% and presents the
highest contents in total phenolics and flavonoids which are of 46.7 ± 2.3 mg gallic acid equivalent /g
dry matter and 2.4 ± 0.1 mg quercetin equivalent/g dry matter respectively. A better antioxidant activity
for the various tests was observed for 50% methanolic and acetonic extracts. The extract of 50% acetone
recorded the most important antifungal activity.

Conclusion:

The findings of this study showed that the extract prepared with the 50% acetone from
Micromeria graeca has the highest phenolics content and revealed the best biological activities. So,
this study has allowed us to find the suitable solvent for the preparation of the M. graeca extract for
several uses.
