New extensions of polygroups by polygroups
Authors: Shehu Lumnije , Khashan Hani
Published: February 2020

Extensions of polygroups such as direct hyper product and wreath product of
polygroups have been introduced and studied earlier by Comer. In this paper,
we define and study some other extensions. We first define regularly normal
subpolygroups and prove that they induce quotient polygroup extensions. In
addition, we prove that the kernel of every strong homomorphism is a
regularly normal subpolygroup. This leads to new versions of the isomorphism
theorems with respect to such subpolygroups. The main objective of the paper
is to present a new extension K of a polygroup L by a polygroup H via the
quotient polygroup H=I where I is regularly normal in H. This extension is a
generalization of both the direct hyper product and the wreath product of
polygroups.
Caristi type and meir-keeler type fixed point theorems
Authors: Pant Abhijit , Pant R.P. , Joshi M.C.
Published: February 2020

We generalize the Caristi fixed point theorem by employing a weaker form of
continuity and show that contractive type mappings that satisfy the
conditions of our theorem provide new solutions to the Rhoades? problem on
continuity at fixed point. We also obtain a Meir-Keeler type fixed point
theorem which gives a new solution to the Rhoades? problem on the existence
of contractive mappings that admit discontinuity at the fixed point. We
prove that our theorems characterize completeness of the metric space as
well as Cantor?s intersection property.
On generalized implicit operator equilibrium problems
Authors: Ram Tirth , Khanna Anu
Published: February 2020

In this paper, we introduce and study a class of generalized implicit
operator equilibrium problems (In short, GIOEP) and derive some propositions
for this class of problems. We also prove some new existence results for the
solution of this problem by using Fan KKM theorems in Hausdorff topological
vector spaces. The results presented in this paper generalize and unify the
corresponding results of several authors which are extensions of previously
known results.
Computing bifurcations behavior of mixed type singular time-fractional partial integrodifferential equations of Dirichlet functions types in hilbert space with error analysis
Authors: Maayah Banan , Yousef Feras , Arqub Omar , Momani Shaher , Alsaedi Ahmed
Published: February 2020

In this article, we propose and analyze a computational method for the
numerical solutions of mixed type singular time-fractional partial
integrodifferential equations of Dirichlet functions types. The method
provide appropriate representation of the solutions in infinite series
formula with accurately computable structures. By interrupting the n-term of
exact solutions, numerical solutions of linear and nonlinear singular
time-fractional equations of nonhomogeneous function type are studied from
mathematical viewpoint. The utilized results show that the present method
and simulated annealing provide a good scheduling methodology to such
singular integrodifferential equations.
On approximately dual frames for Hilbert C*-modules
Authors: Arambasic Ljiljana
Published: February 2020

In this paper we discuss approximately dual frames for a frame or an outer
frame of a Hilbert C*-module. We show that every frame or an outer frame, up
to a scalar multiple, is approximately dual to itself. This enables us to
get a canonical dual frame of a given frame (xn)n as a limit of
approximately dual frames defined by (xn)n.
A generalization on character Connes-amenability
Authors: Shojaee Behrouz
Published: February 2020

In the current paper, we introduce the concepts of left ?-approximate
Connes-amenability and left character approximate Connes-amenability of a
dual Banach algebra A that ? is a ?*-continuous homomorphism fromAto C. We
also characterize left ?-approximate Connes-amenability ofAin terms of
certain derivations and study some hereditary properties for such Banach
algebras. Some examples show that these new notions are different from
approximate Connes-amenability and left character Connesamenability for dual
Banach algebras.

An implicit algorithm for computing the minimal Gersgorin set
Authors: Milicevic S. , Kostic V.R. , Cvetkovic Lj. , Miedlar A.
Published: February 2020

In this paper we present a new algorithm for the computation of the minimal
Gersgorin set that can be considered an extension of the results from [5].
While the general approach to calculation of the boundary of the minimal
Gersgorin set is kept, the core numerical calculation is changed. Namely,
the problem is formulated in such a way that the eigenvalue computations are
replaced by LU decompositions, allowing the algorithm to be used for larger
matrices more efficiently. To illustrate the benefits, we compare both
algorithms on several test matrices.

On the mixed-type generalized inverses of the products of two operators
Authors: Liu Rufang , Zhang Haiyan , Deng Chunyuan
Published: February 2020

Let A, B and be closed range operators. The explicit matrix expressions
for various generalized inverses are obtained by using block operator matrix
methods. Some subtle relationships between the properties of sub-blocks in
operator matrices A, B and their range relations are built. New necessary
and sufficient conditions for the equivalent relations, inclusion relations
and mixed-type generalized inverses relations are presented. Some recent
mixed-type reverse-order laws results are covered and many new mixed-type
generalized inverses relations are established by using this block-operator
matrix technique.

Authors: Garayev Mubariz , Gürdal Mehmet , Yamancı Ulaş , Halouani Borhen
Published: February 2020

For a given function ? ? H? with |?(z)| < 1 (z ? D), we associate some
special operators subspace and study some properties of these operators
including behavior of their Berezin symbols. It turns that such boundary
behavior is closely related to the Blaschke condition of sequences in the
unit disk D of the complex plane. In terms of Berezin symbols the trace of
some nuclear truncated Toeplitz operator is also calculated.

Mixed convection in mhd second grade nanofluid flow through a porous medium containing nanoparticles and gyrotactic microorganisms with chemical reaction
Authors: Khan Noor
Published: February 2020

Mixed convection in magnetohydrodynamic second grade nanofluid flow through a
porous medium containing nanoparticles and gyrotactic microorganisms with
chemical reaction is considered. Buongiorno?s nanofluid model is used
incorporating the buoyancy forces and Darcy-Forchheimer effect. Nanoparticles
increase the thermal conduction in bioconvection flow and microorganisms
simultaneously increase the stability of nanofluids. For the constructive
(or generation) chemical reaction, the mass transfer displays an increasing
behavior. Ordinary differential equations together with the boundary
conditions are obtained through the similarity variables from the governing
equations of the problem, which are solved by the Homotopy Analysis Method
(HAM). The investigations are presented through graphs and the results are
interpreted which depict the influences of all the embedded parameters.

Published: February 2020

Background/Aim. The previous researches suggest that matrix metalloproteinases (MMPs) have the ability to degrade extracellu-lar matrix components and play an important role in malignant tumour progression and metastasis. The aim of this study was to investigate MMP-2 and MMP-9 expression in the tissue of laryn-geal squamous cell carcinoma (LSCC) and to evaluate their clini-cal significance. Methods. In this prospective study the samples of tumour tissue of seventy patients with LSCC (45 glottic and 25 supraglottic), and samples of laryngeal mucosa of 70 patients with chronic laryngitis were immunohistochemically stained for MMP-2 and MMP-9. We studied the relationships between MMPs tissue expression and clinical and histological characteris-tics of the patients with LSCC in comparison to the patients with chronic laryngitis. Results. MMP-2 and MMP-9 expression was significantly higher in the tissue of both glottic and supraglottic LSCC than in chronically inflamed laryngeal mucosa (p < 0.001 and p < 0.001, respectively). There were positive correlations be-tween epithelial MMP-2 expression and the presence of perineu-ral invasion (r = 0.515, p < 0.008), lymphovascular invasion (r = 0.559, p < 0.004) and disease recurrence (r = 0.415, p < 0.039) in supraglottic LSCC, as well as between MMP-2 expression and the presence of the exophytic type of tumour growth (r = 0.347, p < 0.020) in glottic LSCC. Epithelial MMP-9 expression was as-sociated with lymphovascular invasion (r = 0.331, p < 0.026) and the presence of the exophytic tumour growth (r = 0.474, p < 0.001) in glottic LSCC. Conclusion. MMP-2 and MMP-9 can be used as potential biomarkers for the assessment of LSCC progression.
Becoming a university student: An emotional rollercoaster
Authors: Perander Katarina , Londen Monica , Holm Gunilla , Tiihonen Susanne
Published: February 2020

Students’ experiences during their first year of higher education affect study pace, retention and graduation. The aim of this study was to examine how students describe and perceive their studying and academic emotions during the first semester of higher education in order to analyse the interplay of different factors affecting student learning. The students participated in a compulsory study skills course, and wrote about their study experiences in reflective journals (N = 190) that were analysed qualitatively. Reflective journals have been rarely used in previous research on first year studies. The journals allow students to write about their experiences as a whole, and provide a broad and in-depth picture of students’ perceptions of their study habits and learning in higher education. Our results revealed that students’ academic emotions were profoundly affected by their self-regulated learning skills. Moreover, the study showed how self-regulated learning and academic emotions were tightly intertwined. In order to enhance student learning both self-regulated learning and academic emotions need to be considered in university teaching, and when universities plan the first year for new students.
The Observations of Student Teachers in Regard to Professional Qualifications of Advisor Teachers During Teaching Practicum
Authors: Karagöz Savaş , Rüzgar M. Emir
Published: February 2020

This study was conducted to determine the inadequate professional qualifications of

advisor teachers. Employing a qualitative approach, we studied the question “what are
your observations regarding the professional qualifications of the advisor teachers during
the teaching practicum?” with senior students in various programs such as Turkish,
English, mathematics, painting, music and primary school teaching at the Faculty of
Education of a small-scale state university in central Turkey. Analyzing the observations
of the prospective teachers, we identified seven aspects of inadequate qualifications: (1)
professionalism, (2) classroom management, (3) communication, (4) professional
development, (5) personality, (6) creating a democratic classroom environment, and (7)
usage of instructional material and technology. In terms of professionalism, the analysis
yielded that some of the inadequate qualifications are favoring some students over to
others and not having the ability to solve problems. With regard to classroom
management, the most frequent inadequate qualifications are not taking individual
differences into consideration and not being able to ensure student participation to
lectures. Regarding communication, lack of communication among educational
shareholders and negatively criticizing students are mostly mentioned by student
teachers. Based on the findings of the study, we suggest that educational authorities
provide in-service training sessions to teachers to work on these problems so that the
quality of instruction would increase in schools.
Change in the use of remote monitoring of cardiac implantable electronic devices in Italian clinical practice over a 5-year period: results of two surveys promoted by the AIAC (Italian Association of Arrhythmology and Cardiac Pacing)
Authors: Palmisano Pietro , Melissano Donato , Zanotto Gabriele , Perego Giovanni Battista , Toselli Tiziano , Landolina Maurizio , Ricci Renato Pietro
Published: February 2020

Aims

The aim of this study was to evaluate the use of remote monitoring in Italian clinical practice and its trend over the last 5 years.

Methods

In 2012 and 2017, two surveys were conducted. Both were open to all Italian implanting centres and consisted of 25 questions on the characteristics of the centre, their actual use of remote monitoring, applied organizational models and administrative and legal aspects.

Results

The questionnaires were completed by 132 and 108 centres in 2012 and 2017, respectively (30.6 and 24.7% of all Italian implanting centres). In 2017, significantly fewer centres followed up fewer than 200 patients by remote monitoring than in 2012, while more followed up more than 500 patients (all P < 0.005). In most of the centres (77.6%) that responded to both surveys, the number of patients remotely monitored significantly increased from 2012 to 2017.

In both surveys, remote monitoring was usually managed by physicians and nurses. Over the period, primary review of transmissions by physicians declined, while it was increasingly performed by nurses; the involvement of technicians rose, while that of manufacturers’ technical personnel decreased. The percentage of centres in which transmissions were submitted to the physician only in critical cases rose (from 28.3 to 64.3%; P < 0.001). In 86.7% of centres, the lack of a reimbursement system was deemed the main barrier to implementing remote monitoring.

Conclusion

In the last 5 years, the number of patients followed up by remote monitoring has increased markedly. In most Italian centres, remote monitoring has increasingly been managed through a primary nursing model. The lack of a specific reimbursement system is perceived as the main barrier to implementing remote monitoring .
Curcumin inhibits migration and invasion of non-small cell lung cancer cells through up-regulation of miR-206 and suppression of PI3K/AKT/mTOR signaling pathway
Authors: Wang Naizhi , Feng Tao , Liu Xiaona , Liu Qin
Published: February 2020

Curcumin has been proved to inhibit cell proliferation and induce cell apoptosis in non-small cell lung cancer (NSCLC). However, little is known about antimetastatic effects and molecular mechanisms of curcumin in NSCLC. In this study, we investigated the involvement of miR-206 in curcumin’s anti-invasion and anti-migration in NSCLC. Cell proliferation was determined by MTT assay. Cell migration and invasion were analyzed by wound healing assay and transwell assay. MiRNA-206 expression was detected by real-time PCR. Western blot was used to detect the protein expression of PI3K/AKT/mTOR signaling pathway. Curcumin significantly inhibited migration and invasion in A549 cells, accompanied by significantly elevated miR-206 expression. Overexpression of miR-206 could inhibit migration and invasion of A549 cells, but it could also significantly decrease the phosphorylation levels of mTOR and AKT. The inhibition of miR-206 promoted cell migration, invasion and increased the phosphorylation level of mTOR and AKT. Furthermore, miR-206 mimics improved the inhibitory effects of curcumin on cell migration, invasion and the phosphorylation level of mTOR and AKT in A549 cells. On the contrary, MiR-206 inhibitors reversed the inhibitory effects of curcumin on cell migration, invasion and the phosphorylation level of mTOR and AKT. In conclusion, curcumin inhibited cell invasion and migration in NSCLC by elevating the expression of miR-206 which further suppressed the activation of the PI3K/AKT/mTOR pathway.

Authors: Gu Fugen , Fan Huimin , Cong Zhixin , Li Shuang , Wang Yi , Wu Chunzhi
Published: February 2020

Donepezil hydrochloride thermosensitive in situ gel for nasal delivery was prepared by using Poloxamer 407 and Poloxamer 188 as thermoreversible polymers, hydroxypropyl-β-cyclodextrin and ethylparaben as permeation enhancer and preservative, respectively. The gelation temperature and time, pH value of the gel formulation were found to meet the requirements for nasal administration. The in vitro erosion and in vitro release tests exhibited obvious drug sustained release behavior. Meantime, main pharmacokinetic parameters such as t
max, c
max and AUC in plasma as well as in brain were significantly different between the nasal gel formulation and intragastric drug solution in rats (p < 0.01). The relative bioavailability and drug targeting efficiency of the gel formulation were calculated to be 385.6 and 151.2 %, respectively. Thus, the drug gel formulation might be a potential new delivery system for treatment of Alzheimer’s disease due to its higher bioavailability and better distribution to brain when compared to oral route.

Authors: Lima Erica G. , Parpinelli Rejane S. , Santos Pedro R. , Azevedo Alexandre S. B. , Sereia Maria J. , Arnaut de Toledo Vagner A.
Published: February 2020

An alternative to natural food shortage for honeybees is the provision of supplements. The objective of this research was to develop a method with ideal conditions for the fermentation of a protein supplement for honeybees. The microorganisms used were Lactobacilli, Bifidobacteria and Saccharomyces and the inulin prebiotic. There was an increase in lactic acid and a decrease in pH over a five-day fermentation period. The amount of acid bacteria present was 108–109 CFU/g of supplement. In the first phase the temperature and the humidity had significantly affected the fermentation but the variables inulin and probiotic didn’t. In the second phase, the lower temperatures and higher humidity produced the best effects on the fermentative responses. It was concluded that an ideal environment with temperature, humidity, inulin and probiotics could be created which allowed the fermentation of the protein supplement in five days obtaining final product fermentative characteristics close to bee bread.
Socioeconomic inequalities in cancer incidence in Europe: a comprehensive review of population-based epidemiological studies
Authors: Mihor Ana , Tomsic Sonja , Zagar Tina , Lokar Katarina , Zadnik Vesna
Published: February 2020

Background

Since the end of the previous century, there has not been a comprehensive review of European studies on socioeconomic inequality in cancer incidence. In view of recent advances in data source linkage and analytical methods, we aimed to update the knowledge base on associations between location-specific cancer incidence and individual or area-level measures of socio-economic status (SES) among European adults.

Materials and methods

We systematically searched three databases (PubMed, Scopus and Web of Science) for articles on cancer incidence and SES. Qualitative synthesis was performed on the 91 included English language studies, published between 2000 and 2019 in Europe, which focused on adults, relied on cancer registry data and reported on relative risk (RR) estimates.

Results

Adults with low SES have increased risk of head and neck, oesophagogastric, liver and gallbladder, pancreatic, lung, kidney, bladder, penile and cervical cancers (highest RRs for lung, head and neck, stomach and cervix). Conversely, high SES is linked with increased risk of thyroid, breast, prostate and skin cancers. Central nervous system and haematological cancers are not associated with SES. The positive gap in testicular cancer has narrowed, while colorectal cancer shows a varying pattern in different countries. Negative associations are generally stronger for men compared to women.

Conclusions

In Europe, cancers in almost all common locations are associated with SES and the inequalities can be explained to a varying degree by known life-style related factors, most notably smoking. Independent effects of many individual and area SES measures which capture different aspects of SES can also be observed.
Long term response of electrochemotherapy with reduced dose of bleomycin in elderly patients with head and neck non-melanoma skin cancer
Authors: Jamsek Crt , Sersa Gregor , Bosnjak Masa , Groselj Ales
Published: February 2020

Background

Electrochemotherapy (ECT) is a local cancer treatment based on electroporation where the electric field is used to enhance cell membrane permeability and thereby facilitating the transition of chemotherapeutic agents into the cell. For the treatment of non-melanoma skin cancer, a standard dosage of 15,000 IU/m2 bleomycin (BLM) is used. The aim of the present study was to evaluate the long-term ECT response in the group of elderly patients with non-melanoma skin cancer treated with a reduced dose of BLM in comparison to the outcome in the patients treated with the standard dose of BLM.

Patients and methods

Twenty-eight patients older than 65 years, with a total of 52 non-melanoma skin lesions were included in the study. Twelve patients (24 lesions) in the experimental group received a reduced dose of BLM (10,000 IU/m2), 16 patients (28 lesions) were treated with a standard dose of BLM (15,000 IU/m2).

Results

No statistically significant difference in tumor control was observed between both groups. In the experimental group, tumors recurred in 39.0% of treated lesions in a median follow-up time of 28 months. In the control group, the recurrence rate of treated lesions was 15.4% in a median follow-up time of 40 months.

Conclusions

ECT with a reduced dose of BLM is a feasible treatment option for elderly patients with equal efficacy to standard dose treatment and should be considered as a treatment modality in advanced aged patients with comorbidities, where overall life expectancy is poor.
An Intelligent AIEgen with Nonmonotonic Multi-Responses to Multistimuli
Authors: Tu Yujie , Yu Yeqing , Xiao Diwen , Liu Junkai , zhao zheng , liu zhiyang , Lam Jacky W. Y. , Tang Ben Zhong
Published: February 2020

Intelligent stimulus-response (S/R) systems are the basis of natural process and machine control, and have been intensively explored in biomimetic design, analytical chemistry and biological applications. However, nonmonotonic multi-S/R systems are still rarely studied so far. Now, we propose a rational design strategy to achieve such a unique S/R system by integrating opposite luminescence behaviors in one molecule. When solvent polarity increases, many heterocycles often become more emissive due to the suppression of the proximity effect. However, molecules with donor-acceptor (D-A) structures tend to be less emissive because of the twisted intramolecular charge transfer. Meanwhile, protonation on D/A moieties will weaken/strengthen the D-A interaction to result in blue/red-shifted emissions. By combining a protonatable heterocyclic acceptor and a protonatable donor together in one molecule, we can easily achieve nonmonotonic brightness responses to polarity stimuli and nonmonotonic color responses to pH stimuli. In this work, a simple molecule, namely ASQ is chosen as the model compound to verify the design strategy feasibility. It successfully shows two opposite trends of responses to polarity and pH stimuli, and aggregation-induced emission (AIE) with a nonmonotonic AIE curve. Moreover, the acidified ASQ solution is also a pure organic up-conversion and white-light-emitting system. A new mechanistic viewpoint is established to explain its unique anti-Stokes emission. Besides, ASQ shows multivalent functionalities including albumin protein sensing, ratiometric pH sensing, and amine gas sensing, etc. Therefore, ASQ is proved to be a fundamentally important and versatile functional “intelligent” AIE luminogen with nonmonotonic multi-responses to multi-stimuli.
Designing Singlet Fission Candidates from Donor-Acceptor Copolymers
Authors: Blaskovits Jacob Terence , Fumanal Maria , Vela Sergi , Corminboeuf Clemence
Published: February 2020

Singlet Fission (SF) has demonstrated significant promise for boosting the power conversion efficiency (PCE) of solar cells. Traditionally, SF is targeted as an intermolecular process, however its dependence on crystal packing makes molecular design difficult. In contrast, intramolecular SF (iSF) enables the exploration of tunable bi-chromophoric systems following well-defined structure-property relationships. In this work, we propose a set of parameters to screen conjugated donor-acceptor copolymer candidates with potential iSF behaviour. We focus our analysis on the E(S1)>2E(T1) thermodynamic condition and on the appropriate charge transfer (CT) character of S1. We map the CT character with respect to the frontier molecular orbital (FMO) energies of the constituent monomers, providing a cost-effective protocol for an accelerated screening of promising iSF donor-acceptor pairs, while minimizing the number of computations. These parameters are applied to a chemically diverse, curated library of 81 truncated dimers of synthetically feasible donor-acceptor copolymers. From our dataset, four candidates are flagged for iSF, two of which were previously experimentally reported. This protocol is envisioned to be scaled up for the high-throughput screening of large databases of donor-acceptor dimers for the design and identification of conjugated polymers capable of iSF.
Detecting metaphor – what case forms may reveal about a conceptualization
Authors: Sokołowska Olga
Published: February 2020

The figurativeness of language expressions is not always obvious. While in rhetoric such unobtrusiveness may be a welcome quality, in linguistic studies, which have proved the important epistemological function of metaphor, it is vital that a reliable method for detecting metaphoricity in language be developed. The MIP proposed by the Pragglejaz group of researchers into metaphor, whose main concern is determining whether the sense represented by a given unit in a specific context contrasts or not with its basic, primary, typically “physical” meaning, does not seem to be always reliable since the contrast between a current and a basic meaning is not always evident and may be disputable in the case of words whose meaning is co-determined by context, as, e.g., the sense of the noun collectors in the phrase collectors of stories referring to the Grimm brothers. This method is also likely allow for the so-called grammatical metaphors, identified by Panther and Thornburg (2009) going unnoticed, since in their case the words involved represent their basic, physical senses. An example of the latter is the peculiar inflection of brand names marked for the masculine gender in Polish. Specifically, this is the issue of obligatory applying the declensional pattern characteristic of masculine animate nouns to masculine brand names referring to commercial products, such as cars, watches, computers, etc. The point is that the accusative case form of such words functioning as objects of verbs like buy, see, have is equal to the genitive, as is normal of animate nouns, rather than to the nominative, which is typical of animate ones – a group, to which brand names, after all, belong. This peculiar behaviour of a specific category of nouns may be interpreted as a symptom of construing their referents in a way in terms of living creatures, which seems to be confirmed by the fact that many owners develop emotional attitudes to objects of personal use. It is the metaphorical construal that seems to determine the grammatical form of certain nouns referring to them.
Machine Learning-Based Distributed Denial of Service Attack Detection on Intrusion Detection System Regarding to Feature Selection
Authors: Azhari Ahmad , Muhammad Arif Wirawan , Foozy Cik Feresa Mohd
Published: February 2020

Distributed Service Denial (DDoS) is a type of network attack, which each year increases in volume and intensity.  DDoS attacks also form part of the major types of cyber security threats so far. Early detection plays a key role in avoiding the catastrophic effects on server infrastructure from DDoS attacks. Detection techniques in the traditional Intrusion Detection System (IDS) are far from perfect compared to a number of modern techniques and tools used by attackers, because the traditional IDS only uses signature-based detection or anomaly-based detection models and causes a lot of false positive flags, since the flow of computer network data packets has complex properties in terms of both size and source. Based on the  deficiency in the ordinary IDS, this study aims to detect DDoS attacks by using machine learning techniques to enhance IDS policy development.  According to the experiment the selection of features plays an important role in the precision of the detection results and in the performance of machine learning in classification problems. The combination of seven key selected dataset features used as an input neural network classifier in this study provides the highest accuracy value at 97.76%.
Predictors of Adolescent Academic Achievement: The Role of Individual and Family Socioeconomic Factors
Authors: Latifah Melly , Amelia Rizky
Published: February 2020

Academic achievement is affected by external and internal factors. This study generally aims to examine the influence of family characteristics (per capita income and parental education), individual characteristics (age and gender), cognitive intelligence, and self-regulated learning toward academic achievement in adolescents. A total of 91 samples (Mage=13.9 years) with the largest percentage of the respondents were women were selected from two different junior high schools in Bogor area. Cognitive intelligence, self-regulated learning, and academic achievement were measured using Riley Inventory Basic of Learning Skills (RIBLS), Motivated Strategies for Learning Questionnaire (MSQL), and student academic record, respectively. The partial regression analysis showed there was a negative effect of mother’s education on self-regulated learning. Gender was found to positively predicted cognitive intelligence. The regression analysis also showed that parental education and cognitive intelligence positively predicted adolescent academic achievement. Per capita income, gender, and self-regulated learning showed no significant effects on academic achievement.

Reducing import tariff rates under the ASEAN-CEPT scheme was considered not significantly to enhance trade flows within the region. Trade facilitation instruments such as mutual recognition arrangement, harmonization on customs procedure and the improvement of other trade-supporting infrastructure were then introduced by the members. Gravity model used in this paper identified a positive impact of such policies in improving trade atmosphere. Local governments can actively play an important role in supporting the conducive environment by providing an efficient bureaucratic system and facilities surrounding harbors. This then reduce transaction cost facing by the private sector and expectedly improve local economic activity in the region.Keyword: ASEAN, Trade Facilitation, Local Government

More than 50% of the world’s population is infected with Helicobacter pylori. H. pylori is the major causative agent of gastric ulcers and gastric cancer. H. pylori eradication using antibiotics either alone or together with a proton pump inhibitor is the primary strategy to decrease the incidence of gastric cancer. Although eradication therapy is effective, there are significant adverse effects and more importantly, resistance to antibiotics occurs, which represents a major therapeutic challenge. Multiple natural products have been shown to suppress H. pylori both in vitro and in animal model systems. However, only a handful of natural products have been evaluated in human clinical trials. The focus of this review is to summarize the results of published human clinical trials to assess the ability of natural products to reduce or eliminate H. pylori infections. Current evidence suggests that these products appear to have great potential to be developed as pharmaceutical candidates for eradication of H. pylori, hopefully both antibiotic‐sensitive and antibiotic‐resistant strains. Frequent consumption of locally produced foodstuff for controlling H. pylori infection in different countries around the world may well be a feasible long‐term solution to fight against this worldwide prevalent pathogen.

Authors: Nugraheni Raditya Weka
Published: February 2020

Microemulsion is a transparent, isotropic and thermodynamically stable preparation. Tea tree oil (TTO) is an essential oil extracted from the leaves of Melaleuca alternifolia by steam distillation which has been proven to have antibacterial and fungal uses. Optimization of microemulsion preparations to obtain preparations with small and stable droplet size is also a challenge. The design of an experiment is to design an experiment with a certain pattern, with a combination of certain input variables that allow to shorten the number of experiments. Based on the research results, it is known that the most influential factor on the microemulsion particle size is the combination of surfactants polysorbate 80 with co-surfactants propyleneglycol.

Pertumbuhan penduduk di Kabupaten Tulungagung yang semakin pesat harus diimbangi dengan sarana prasarana transportasi yang memadai. Peningkatan sarana dan prasarana transportasi ini berupa pembangunan jembatan. Jembatan merupakan salah satu akses yang menghubungkan antara daerah yang satu dengan daerah lainnya yang terpisah karena keadaan alam, misalnya adanya lembah, jurang, sungai maupun rel kereta api. Dalam merencanakan kontruksi jembatan, selain menyesuaikan dengan perkembangan lalu lintas dan tonase kendaraan yang lewat juga harus mempertimbangkan keadaan dan lokasi di mana jembatan itu akan dibangun. Namun tidak berarti jembatan harus dibuat lebih kuat dan tidak memperhatikan faktor ekonomisnya. Mengingat faktor ekonomis dan kekuatan dari kontruksi jembatan tersebut, maka dalam perencanaan jembatan diusahakan menghasilkan kontruksi yang dapat menjamin kekuatannya dan paling ekonomis ditinjau dari segi biaya pembangunan maupun pelaksanaannya.Jembatan Sendang (Ruas Jalan Tugu – Pabyongan)dengan bentang 36 meter ( 3 x 12m ) dengan lebar 7 meter merupakan proyek Dinas PU Bina Marga dan Cipta Karya Kabupaten Tulungagung, Anggaran Pendapatan dan Belanja Daerah (APBD) Tahun 2016. Jembatan tersebut menghubungkan Kecamatan Sendang sebagai kawasan wisata dan agropolitan penghasil sayur-sayuran terbesar se Kabupaten Tulungagung. Jembatan Sendang memudahkan distribusi buah dan sayur ke seluruh wilayah karisidenan Kediri khususnya Kabupaten Tulungagung. Jembatan Sendang tersebut berada di atas sungai Song  yang memiliki debit air sedang dan membesar ketika hujan.Daerah Sendang terletak di kaki gunung Wilis dimana akan dibangun Proyek Lingkar Wilis oleh Pemprov Jawa Timur yang menghubungkan Wilayah Trenggalek, Kediri, Tulungagung, danj Ponorogo. Jembatan Kecamatan Sendang (Ruas Jalan Tugu Pabyongan) ini merupakan jembatan yang akan dilewati oleh proyek tersebut, sehingga studi jembatan ini sangat diperlukan untuk menunjang pembangunan tersebut.Kata kunci : Jembatan, Komposit, Struktur atas
