Published: December 2020

This paper reports the fabrication and electrical characterization of hybrid organic-inorganic solar cell based on the deposition of polyaniline (PANI) on n-type GaAs substrate with three different crystal orientations namely Au/PANI/(100) n-GaAs/(Ni-Au), Au/PANI/(110) n-GaAs/(Ni-Au), and Au/PANI/(311)B n-GaAs/(Ni-Au) using spin coating technique. The effect of crystallographic orientation of n-GaAs on solar cell efficiency of the hybrid solar cell devices has been studied utilizing current density-voltage (J-V) measurements under illumination conditions. Additionally, the influence of planes of n-GaAs on the diode parameters of the same devices has been investigated by employing current-voltage (I-V) characteristics in the dark conditions at room temperature. The experimental observations showed that the best performance was obtained for solar cells fabricated with the structure of Au/PANI/(311)B n-GaAs/(Ni-Au). The open-circuit voltage (Voc), short circuit current density (Jsc), and solar cell efficiency () of the same device were shown the values of 342 mV, 0.294 mAcm-2, 0.0196%, respectively under illuminated condition. All the solar cell characteristics were carried out under standard AM 1.5 at room temperature. Also, diode parameters of PANI/(311)B n-GaAs heterostructures were calculated from the dark I-V measurements revealed the lower reverse saturation current (Io) of 3.0×10-9A, higher barrier height () of 0.79 eV and lower ideality factor (n) of 3.16.

Published: December 2020

Telah dilakukan pembuatan molecular imprinted polymer (MIP) nano karbaril dengan metode cooling-heating. Pembuatan MIP nano karbaril bertujuan untuk mendapatkan material sensor yang potensial dalam aplikasinya. Dalam penelitian ini, bahan aktif karbaril di-milling dengan variasi waktu 10 menit dan 15 menit. Pada proses polimerisasi melibatkan templat nano karbaril, methacrylic acid (MAA) sebagai monomer fungsional, ethylene glycol dimathacrylate (EDMA) sebagai crosslinker, benzoil peroksida (BPO) sebagai inisiator, dan acetonitril sebagai pelarut yang disintesis menggunakan metode cooling-heating. Dengan cara yang sama, non-imprinted polymer (NIP) juga dibuat sebagai polimer kontrol.  NIP merupakan polimer yang dibuat dengan komposisi dan cara yang sama dengan MIP, namun tidak ditambahkan nano karbaril sebagai zat aktif. Pembuangan templat pada proses ekstraksi sangat berperan penting untuk menghasilkan material sensor yang baik. MIP, polimer, dan NIP yang dihasilkan di karakterisasi menggunakan Fourier transform infrared (FTIR) dan sampel terbaik dideteksi lebih lanjut dengan uji x-ray diffraction (X-RD), dan scanning electron microscope (SEM). Hasil FTIR menunjukkan bahwa gugus fungsi spesifik nano karbaril pada NIP tidak tampak bila dibandingkan dengan spektra MIP, dan terjadi penurunan persen transmitansi pada polimer dan peningkatan % transmitansi pada MIP. Hal ini menjelaskan bahwa terjadi penurunan konsentrasi nano karbaril pada MIP setelah proses ektraksi. Hasil X-RD menunjukkan ukuran kristal yaitu 9,16 Å. Hasil SEM menunjukkan bahwa jumlah pori tercetak dengan ukuran ≤100 nm yaitu 383 pori.  Data ini mengindikasikan bahwa MIP nano karbaril potensial untuk diaplikasikan sebagai material sensor.
Quantum-Mechanical Brayton Engine for the Nonrelativistic Particle Trapped in a Symmetric Potential Box
Authors: Abdillah Fikri , Saputra Yohanes Dwi
Published: December 2020

A theoretical quantum Brayton engine research has been carried out using a potential box system to increase its thermal efficiency. The method applied in this research is a classical thermodynamics system model in the form of a piston tube containing a monatomic ideal gas analogous to a quantum model in the form of a potential box containing one particle.  The efficiency formulation of the quantum Brayton engine obtained from this study is following the classical version. However, the efficiency value obtained on a quantum Brayton engine is higher when compared to its classic. It happens because the value of the Laplace constant owned by the Brayton quantum version is 3, while the classic version is 5/3.

Solution-State Preorganization of Cyclic β-Hairpin Ligands Determines Binding Mechanism and Affinities for MDM2
Authors: Ge Yunhui , Zhang Si , Erdelyi Mate , Voelz Vincent
Published: December 2020

Understanding mechanisms of protein folding and binding is crucial to designing their molecular function. Molecular dynamics (MD) simulations and Markov State Model (MSM) approaches provide a powerful way to understand complex conformational change that occurs over long timescales. Consideration of such dynamics are important for the design of therapeutic peptidomimetic ligands, whose affinity and binding mechanism are dictated by a combination of folding and binding. To examine the role of preorganization in peptide binding to protein targets, we performed massively parallel explicit-solvent MD simulations of cyclic β-hairpin ligands designed to disrupt the MDM2-p53 interaction. MSM analysis of over 3 ms of aggregate trajectory data enabled us to build a detailed mechanistic model of coupled folding and binding of four cyclic peptides which we compare to experimental binding affinities and rates. The results show a striking relationship between the relative preorganization of each ligand in solution and its affinity for MDM2. Specifically, changes in peptide conformational populations predicted by the MSMs suggest that entropy loss upon binding is the main factor influencing affinity. The MSMs also enable detailed examination of non-native interactions which lead to misfolded states, and comparison of structural ensembles with experimental NMR measurements. In contrast to an MSM study of p53 TAD binding to MDM2, MSMs of cyclic β-hairpin binding show a conformational selection mechanism. Finally, we make progress towards predicting accurate off-rates of cyclic peptides using multiensemble Markov models (MEMMs) constructed from unbiased and biased simulated trajectories.

For Dr. Leggo: A Legend
Authors: Lee Karen V
Published: December 2020

Abstract: The author reflects on the death of professor who was on her doctoral committee.  She considers how “grief and bereavement has undergone a transformational change in terms of how the human experience of loss is understood, “(Hall, 2014, p. 7).  The article explores how “poems are powerful documents that possess the capacity to capture the contextual and psychological worlds of both poet and subject,” (Furman, 2007, p. 302).  It also explores how reflexivity can be enacted through a poetic inquiry (Prendergast, Leggo, Sameshima, 2009).  Thus, the narrative can contextualize “using alternative forms of data to evoke deep and powerful emotional reactions in the consumer of research,” (Denzin, 1997).   In the end, the narrative weaves poetic inquiry that helps the author gain a deeper understanding about the personal and cultural influences of grief and how it transforms reflections on death, dying, life, and loss.
Keywords: Death; Grief; Loss; Poetic Inquiry.
Résumé : L’autrice se penche sur le décès d’un professeur qui siégeait sur son comité de doctorat. Elle examine le changement transformationnel de la « peine et du deuil au niveau de l’interprétation de la perte dans le cadre de l’expérience humaine » (Hall, 2014, p. 7). L’article décrit « en quoi les poèmes constituent de puissants documents capables de saisir les univers contextuel et psychologique aussi bien du poète que du sujet » (Furman et al., 2007, p. 302). On y apprend aussi comment la quête poétique peut donner forme à la réflexivité (Prendergast et al., 2009). Le narratif peut donc contextualiser « l’utilisation d’autres formes de données pour évoquer de puissantes et profondes réactions émotionnelles chez le consommateur de recherches » (Denzin, 1997). En bout de ligne, le narratif tisse la quête poétique qui permet à l’autrice de mieux comprendre le concept de la peine et son impact sur la réflexion de concepts tels que la mort, la vie, la fin de la vie et la perte.

Use of waste plastics for the preparation of adhesives for wood bonding
Authors: Šernek Milan , Turičnik Vanja , Repič Rožle , Šega Bogdan
Published: December 2020

There is more and more plastic waste, so we try to find different ways to recycle and reuse it. Recycled thermoplastic polymers represent an interesting potential for the production of adhesives, so the aim of our preliminary investigations was to examine the suitability of waste polystyrene for the production of adhesives for wood bonding. The adhesive mixtures were prepared by cutting waste polystyrene cups (L) and coffee spoons (Ž) into smaller pieces and dissolving them separately in five different solvents: Butyl acetate (BA), Dimethylformamide (DMF), Tetrahydrofuran (THF), Limonene (L) and Acetone (AC). From these we prepared composite samples of two beech lamellae (Fagus sylvatica L.), which were pressed for 10 minutes in a hydraulic press at a temperature of 150 °C and a pressure of 12 bar. In order to determine the quality of the bonding, we carried out a shear test with a Zwick/Roell Z005 universal testing machine. We found that the test specimens bonded with the adhesive mixture Ž-DMF achieved an average shear strength of 6.5 N/mm2 and the test specimens bonded with L-DMF achieved 3.8 N/mm2. All other test specimens showed a lower strength of the adhesive bonds, or they mostly delaminated after hot pressing or later during sawing into test specimens. In further research work we will modify these promising adhesive mixtures and optimise the pressing parameters in order to achieve bonding quality that meets the standard requirements for thermoplastic adhesives for interior applications.
MIMO Antenna Design and Optimization with Enhanced Bandwidth for Wireless Applications
Authors: Reddy Mekala Harinath , Seela D.
Published: December 2020

This paper demonstrates a compact MIMO (Multi Input Multi Output) fractal type antenna for ultra-wide band applications. The proposed antenna is manufactured on a lowcost substrate material and the design is analyzed for various iterations in terms of reflection coefficient, gain, and bandwidth. The 50 Ω transmission line feed is used for both fractal patches and a metamaterial structure is used as the ground plane. The proposed design achieved a wide-band frequency response between 5.8 and 15 GHz, with the reflection coefficient of less than –10 dB. Reduced mutual coupling, positive gain and stable radiation patterns were observed throughout the operating band as well. The bandwidth of 9.2 GHz is achieved with the use of a metamaterial structure on the ground plane. The ECC and diversity gain obtained prove the excellent diversity performance of the antenna. The design was simulated using HFSS software and was tested in a lab.

This article presents the findings from the first 3 years of the evaluation of Healthy Families NZ, a systems-change intervention to prevent chronic diseases in 10 communities. The initiative, which builds on existing prevention activities, aims to strengthen the health prevention system through evidence-driven action to enable people to make good food choices, be physically active, smoke-free and free from alcohol-related harm. Key investment areas are a dedicated systems thinking and acting health promotion workforce, and activating leaders who can influence transformational change. The evaluation to date has found the initiative is being implemented with integrity. Evidence indicates a shift towards greater action on prevention, and the prevention system being strengthened. Māori ownership has been enabled, and prioritizing equity has led teams to utilize methods that amplify diverse local perspectives. There is progress on developing a flexible workforce through adaptive learning, flexible resources, professional development and a responsive National team. There is also progress in activating local leadership and empowering local teams. The initiative design has explicitly taken into account the context of complexity within which it is being implemented. It has evolved to focus on action that can accelerate sharing information and practices within communities, and between policy and decision-makers. Healthy Families NZ and its evaluation have been refunded to 2022. This provides an important opportunity to gather further insight into effective ways to strengthen the community agency and trust needed to promote and deliver evidence-based action on prevention.

Authors: Palermo Stefano
Published: December 2020

The history of the Cassa per il Mezzogiorno and its role to counter the regional inequality in Italy during the second hal of 1900s has been the subject of numerous studies and in-depth studies. From a purely quantitative point of view, the overall analysis of the financial statements highlighted how the Cassa managed to allocate between 1950 and 1986 over € 104,180 million (at constant 2011 prices). The results of this important financial mass were variable and different were the tools and models of interpretation adopted by historiography. Particularly important is the question of territorial analysis of interventions and their regional and provincial distribution. The aim of the essay is to present a model of study of the role and strategies of the case of the Cassa per il Mezzogiorno between 1950 and 1992 on a territorial level based on the use of a new series of quantitative character developed through the reorganization of the Cassa electronic accounting sources recently deposited at the Central State Archive of Italy. The research thus makes it possible to deepen some aspects of the Cassa activity, its account management and to make a comparison with the main evidences demonstrated by the historiography on the intervention strategies adopted by it.

The emergence of the Covid-19 as the global pandemic with its social and physical distancing consequence has affected educational practices. This paper reports the expereince of carrying out a study on applying youtube video for writing of descriptive text in EFL Class. The purpose of this research was to find out whether the videos can develop studentsâ€™ ability in writing descriptive text or not.Â  The study took place in the time before and during the covid-19 emergence. As quantitative research, this study applied pre-experimental design. The participant of this research was the 1st year students of one of the prominence senior high schools in Manado, Indonesia. They were 26 students of language class. The results indicated that the mean score of the post-test is significantly higher that of the pre-test. This points out that the use of YouTube video in teaching the writing of descriptive text is effective. However, the emergence of Covid-19 pandemic influenced the implementation of intervention that later affected studentsâ€™ achievement. The result of this study is not fully in line with the outcome of the previous studies which hypothetically resulted in two to four gains of scores. In addition, it implies that the use of YouTube video in this pandemic transition period seems to be helpful mostly to low level students as they displayed higher gains. Besides, this study denotes the challenges for teachers and students in the Covid-19 pandemic era namely the competence in online learning, and the internet connectivity access and learning mode system.

It is quite common to our understanding that classroom assessment outcomes are not sensitive to the goal of teaching and learning language skills. More specifically, the assessment cannot allow the students to present what they know and what they are supposed to do. The purpose of classroom assessment is to inform teaching and to improve learning. Performance assessment gives the students a chance to demonstrate their knowledge and absorb a wide variety of information on language teaching and learning activities. This study aims to analyze the implementation of performance assessment in improving students' writing skills and disclosing the students' psychological factors on implementing performance assessment in the writing learning process. This is a descriptive qualitative study that was carried out for three months, namely October-December 2018. The participants of the research were 28 English department students of Udayana University. The instruments used were writing rubric, questionnaires, and interviews.Â  These data were analyzed with the assistance of the excel chart data series software program and then followed by qualitative interpretation. The questionnaire data were displayed in the form of a percentage, while the data from the interviews were narrated in detail based on students' responses. The findings of the study reported a positive impact on students' writing skills (the mean post-test result = 78), boosts students' interest and awareness (92,85%), self-esteem (85,71%), and their motivation (78,57%). The practitioners are expected to implement performance assessment in enhancing students to be a competent English writer.

This paper seeks to examine the emerging sociolinguistic trends in Nigeria with the view to ascertaining the use of English as a first language among its speakers particular in Calabar, Nigeria. The study adopts Vygotskyâ€™s (1978) Social Interactionist Theory. The theory is relevant because it accounts for the intentional and changing linguistic attitudes of children believed to be influenced by their early exposure to English as the language spoken by adults and peers within their immediate environment. Data for the study were generated through primary sources, particularly by means of participant observation and administration of questionnaire. Using random sampling technique, 468 questionnaires were distributed to children within the school age bracket of 06 - 13 in 10 selected Private Primary and Junior Secondary Schools in Calabar. With the aid of 20 trained research assistants who are bi/multilinguals in some Nigerian indigenous languages and English, 400 questionnaires filled under supervision were retrieved from the respondents from where the data were extracted and collated for analysis. Findings indicate that 37 percent of the pupils/students are monolinguals who speak only English as their â€˜first and native languageâ€™. Similarly, 32.5 percent of the target population understand their mother tongue(s) while 30.8 percent of affirm that they speak the indigenous language(s) fluently. Also, it is observed that a total of 63 percent are bi/multilinguals in their mother tongue(s) and English language and could switch or mix codes. The reasons for the increasing preference towards English language, the researchers have observed, range from the persuasive influence from parents, teachers and peers, and the consequences of globalization in addition to the multiple domains of use of English language. This trending communication practice would continue to increase the growing population of English speakers in Nigeria while the indigenous are further endangered.

In recent decades users have emphasized that traditional financial reporting is beginning to lose the

relevance of the value of earnings and the book value of equity. To cover these weaknesses, investors began to look for other information to make investment decisions. Intellectual capital is included in the top ten in the information needed by information users. Intellectual capital is a potential source for modern companies to gain competitive advantages that are difficult for competitors to imitate and drive business development and success in the future. This study aims to examine the value relevance of disclosure of intellectual capital information on traditional industrial and non-traditional companies, and examine what factors influence companies to disclose intellectual capital.

Using the purposive judgment sampling method, the company sample consisted of 68 companies from various types of industries that were listed on the Indonesia Stock Exchange in 2014-2018. The results is disclosure of intellectual capital has value relevance in traditional companies, but in non-traditional companies there is not enough evidence found that disclosure of intellectual capital has value relevance. Company age, audit quality, market book ratio, company size, and type of industry have a strong influence on intellectual capital disclosure. Whereas leverage and profitability have no influence on intellectual capital disclosure.

Peningkatan produktivitas pertanian adalah kunci penting bagi negara untuk dapat sejahtera. Realisasinya kemajuan sektor pertanian memiliki keterkaitan erat dengan seluruh pelaku ekonomi baik petani,industrialis, pemerintah dan koperasi. Penelitian ini bertujuan untuk mengetahui perkembangan nilai produksi bawang putih di Indonesia dan China periode 1991-2016 serta  kontribusi pemerintah dalam mewujudkan swasembada bawang putih di Indonesia 2021. Metodologi penelitian yang digunakan adalah pendekatan deskriptif kuantitatif yaitu persamaan trend.  Data yang digunakan adalah data sekunder yang bersumber dari Food Agriculture Organization (FAO). Dari hasil perhitungan menunjukkan perkembangan nilai prodksi bawang putih di Indonesia menurun sedangkan China meningkat per tahun. Faktor utamanya tidak optimalnya penggunaan luas lahan untuk budidaya bawang putih terutama di Pulau Jawa akibat lemahnya regulasi pemerintah terhadap pengusaha impor. Sebaliknya peningkatan nilai produksi di China karena tingginya peran pemerintah dalam sektor pertanian, tingginya kualitas SDM dan peningkatan skala ekonomi. Konribusi dari pemerintah Indonesia adalah  memperbaharui regulasi yang berorientasi jangka panjang dan lebih menyejahterkan petani, siap memberikan pendampingan aspek budidaya dan teknologi serta  mewadahkan petani dalam organisasi koperasi pemasaran  dalam menjalin hubungan dengan semua pihak terkait dalam mewujudkan swasembada bawang putih di Indonesia.

Combining 308-monochromatic excimer phototherapy with monthly IM triamcinolone acetonide for the treatment of resistant alopecia totalis
Authors:   Department of Dermatology, Diwaniyah Teaching Hospital, Diwaniyah, Iraq
Published: December 2020

Background: Treatment of resistant alopecia totalis AT is a major problem in general practice. Some studies reported the use of either excimer-308 or intra-muscular triamcinolone acetonide as a monotherapy, with conflicting results. Objective: To evaluate the therapeutic effect of combining 308-excimer phototherapy and intramuscular triamcinolone acetonide for the treatment of alopecia totalis. Methods and Material: Ten patients with alopecia totalis were evaluated in this prospective interventional study. All patients were assigned to receive the thera-peutic regimen that includes monthly IM triamcinolone acetonide (TAC) for a maximum of six pulses and twice-weekly excimer phototherapy for 24 sessions. Results: The overall response rate for this regimen was 90%, with four patients 40% achieving complete regrowth of hair (100%). Three patients have exhibited a satisfactory response (>70% regrowth). Unsatisfactory response ( >10-< 70% regrowth) was reported in two patients . Younger patients responded better, as did those with a shorter history of the disease P < 0.05. At follow-up, which continued for 8–12 months, recurrence was noted in two (22.2%) of the nine responders. Conclusions: Combining excimer phototherapy with triamcinolone acetonide showed a promising effect on resistant AT. This treatment modality was effective and well tolerated particularly in young patients.
Some Univalence Conditions of a Certain General Integral Operator
Authors: Barbatu Camelia , Breaz Daniel
Published: December 2020

For some classes of analytic functions f, g, h and k in the open unit disk U, we consider the general integral operator Tn, that was introduced in a recent work [1] and we obtain new conditions of univalence for this integral operator. The key tools in the proofs of our results are the Pascuâ€™s and the Pescarâ€™s univalence criteria, as well as the Mocanuâ€™s and erbâ€™s Lemma. Some corollaries of the main results are also considered. Relevant connections of the results presented here with various other known results are briefly indicated.
Applications of Lacunary Sequences to Develop Fuzzy Sequence Spaces for Ideal Convergence and Orlicz Function
Authors: Raj Kuldip , Mohiuddine S. A.
Published: December 2020

In the present paper, we introduce and study ideal convergence of some fuzzy sequence spaces via lacunary sequence, infinite matrix and Orlicz function. We study some topological and algebraic properties of these spaces. We also make an effort to show that these spaces are normal as well as monotone. Further, it is very interesting to show that if $I$ is not maximal ideal then these spaces are not symmetric.
