Authors: Simon Miriam R , Bixler Gregory D , Doudican Bradley , Dzwonczyk Roger
Published: March 2018

The service learning engineering/humanitarian engineering, program at The Ohio State University has been in existence for seven years and has grown in both the number of participants and projects. On the international front, various partnerships have formed that create a framework for success for our participants as well as for targeted communities that are served. The program, although focused mostly on engineering-related projects, also emphasizes the need for cultural awareness and constant communication with the in-country partners. The goal of the program is to raise awareness of the needs of citizens in developing nations and to collectively work together on sustainable solutions. This paper will describe the development of humanitarian engineering at The Ohio State University and chronicle the partnership in two specific locations in Honduras.

Authors: De Chastonay Anne , Bugas Michael , Soni Shreya , Swap Robert
Published: March 2018

This paper presents a sustainable cook stove project made possible by a partnership between a United States university and a South African community.  Faculty and students from the University of Virginia and the Mashamba Primary Presidential School collaborated to produce a cleaner and more sustainable method of cooking. The Rocket Stove, a high efficiency stove that uses wood as fuel, was adapted and implemented in the Mashamba Primary Presidential School in 2010 through a collective effort from both the University and Mashamba.  Since then, University of Virginia students have revisited Mashamba and are now working closely with the primary school to determine the positive and negative impacts the cookstoves have instilled on the community. As collaboration between the University of Virginia and Mashamba Primary School continues and more knowledge about the integration of the stoves is revealed, the partners hope to disseminate information about the Rocket Stove to other portions of the region.  The following is a story about the implementation of the rocket stove within a community. It is also a story of how service learning and engaged scholarship can produce a sustainable solution impacting what development means to a community, creating a ripple effect within an entire region.
Designing a Low-Cost Ceramic Water Filter Press
Authors: Henry Michael , Maley Siri , Mehta Khanjan
Published: March 2018

Diarrheal disease due to unsanitary water is a leading cause of death in low- and middle- income countries. One potential solution to this problem is widespread access to point-of-use ceramic water filters made from universally-available materials. This increased access can be achieved by empowering local artisans to initiate self-sustaining and scalable entrepreneurial ventures in their communities. However, a major barrier to the start-up of these businesses is the prohibitively expensive press used to form the filters. This article reviews filter press technologies and identifies specific functional requirements for a more suitable and affordable filter press. Early-stage field-testing results of a proof-of-concept design that can be manufactured by two people in two days at one-tenth of the cost of popular filter presses is presented.

Authors: Tucker Bowa George , Kazmer David O. , Bielefeldt Angela R. , Paterson Kurt , Pierrakos Olga , Soisson Annie , Swan Chris
Published: March 2018

Over the past decade, Learning through Service (LTS) has proliferated in higher education as an effective teaching and learning method.  LTS is an umbrella term that includes both curricular and extracurricular activities, recognizing that there are many models that exist currently for how faculty members use opportunities for students to learn while providing service to a community.  Reflection by the students on their service activity provides rich opportunities for students to add meaning to their learning through engagement with community.  While, many colleges and universities in the United States have increased the use of LTS in engineering programs, there has been limited study to evaluate engineering faculty perception of the purpose of reflection in support of facilitating and assessing the expected learning outcomes.  In this research, twenty-six interviews were conducted with engineering LTS practitioners to explore how and why engineering faculty incorporate reflection in LTS efforts.  The findings reveal that majority of engineering LTS faculty practitioners engage students in reflection to enhance the professional development skills of their students, with fewer of the faculty using reflection to develop students’ personal skills.

IMPLIKASI HUMOR DAN PERAN LAYANAN KARYAWAN GARIS DEPAN TERHADAP KEPUASAN PELANGGAN
Authors: Mulyati Widya , Kristaung Robert
Published: March 2018

This study aims to examine the implications of humor and the role of front-line employee services to customer satisfaction. The effect of front-line service employees calculates the factor of service encounters. The service encounter factor becomes one of the decisive factors in the service industry, especially the banking industry, especially in the era of digitization as the interaction between employees and customers is still needed. The research design used is hypothesis testing between humour, front-line service employees, to customer satisfaction by service encounter. The sample of this research is supported by 150 workers consisting of teller, customer service, and head teller/customer service department who participate as the respondent in this research. This research uses SEM analysis. The result of this research supports the hypothesis that humor positively effects frontline service employees and front -line service employees affect the service encounter. This research fails to prove that service encounter has a significantly direct effect on customer satisfaction. Therefore, the implication of service encounter is still a crucial point for the banking industry in achieving customer satisfaction.

Ethnic uses of Makhana (Euryale ferox Salisb.) in Mithila (north Bihar) and other parts of India
Authors: Kumari Anubha , Jha Vidyanath
Published: March 2018

The paper provides a report on the ethnic uses of Makhana (Euryale ferox Salisb.) in different parts of India including Mithila area of North Bihar that is known for being a site of its organized cultivation over centuries. In major parts of northern India E. ferox is available in wild or semi-wild forms. A survey on the ethnic uses of Makhana in Mithila and other parts of India has revealed its about a dozen distinct uses. These include its specific association with (i) ‘Kojaagaraa’ (a marital ritual) (ii) ‘Parikramaa’ (for maintaining counts during ritualistic circumambulation around a temple or tree) (iii) ‘Shraaddha Karma’ (last Hindu rites) (iv) Devotional offering to deities or distinguished persons in the form of non-flower garlands (v) ‘Prasaad’ (edible offering to deities) (vi) Sacred thread ‘Yajnopaveet’ as stiffening item (vii) ‘Makhaan Paagal’ i.e., caramelised pops (during Navratri and other festivals). It is used as a ‘Havan Saamagri’ and as a component of ‘Panchamevaa’ (i.e., five auspicious dry fruits). ‘Ghunes’, a head gear ceremonially worn by the bridegroom on the occasion of wedding has streams of Makhana pops hanging downward. This practice is observed by the Srotriyas in this area. The paper further incorporates its other traditional and modern uses mostly in the form of culinary preparations. These are also in practice in other areas of the country and abroad in the form of (i) 2 forms of snacks (ii) Dessert (iii) Sweetened Makhana (iv) Porridge (v) Dal Makhani (vi) Makhana Kofta and (vii) Makhana Dum Aloo.

Silica  gel  was  modified  via  silylation  using  3-chloropropyltrimethylsilane  and functionalization  using  1,10-phenanthroline.  FTIR,  DSC  and  quantitative  SEM-EDX  data were obtained to confirm functionalization. The uptakes of cadmium (II) and lead (II) by the phenanthroline-modified  silica  (Phen-Si)  were  determined  using  equilibrium  and  dynamic methods.  For  the  equilibrium  method,  percent  adsorbed  for  5  to  200  ppm  metal  ion solutions  ranged  from  0  %  to  93.2  %  (for  Cd)  and  from  81.6  %  to  95.2  %  (for  Pb)  The maximum  uptake  of  Phen-Si  is  91.89  mg  Pb/g  silica  and  93.06  mg  Cd/g  silica  for  the equilibrium method while for the dynamic method, maximum uptake was 25.65 ± 6.52 mg Pb/g silica and 17.68 ± 2.33 mg Cd/g silica.
Efficient Oxidative Desulfurization of Model Oil at Room Temperature with Ionic Liquid as Extraction Solvent
Authors: Chiu Harold Henrison C. , Arco Susan D. , Ping Zhang Chun , Villarante Nelson R.
Published: March 2018

The oxidative desulfurization of model oil (hexane solution of thiophene) was carried out at room temperature in a two-step method involving: 1) the acetic acid catalyzed oxidation of thiophene with hydrogen peroxide and 2) the subsequent extraction of the oxidized products with  three  1-alkyl-3-methylimidazolium  bromide  [RMIM]Br  ionic  liquids  of  varying  alkyl substituent R chain length  (R: C2, C4,  C6) and with acetonitrile as control. For purposes of comparison,  a  non-oxidative  extractive  desulfurization  of  model  oil  with  the  above  ionic liquid and with acetonitrile was also performed.  The thiophene extraction efficiencies of the ionic liquids and that of the control in both the oxidative and non-oxidative procedures were determined  by  means  of  gas  chromatography.  The  ionic  liquid  of  the  shortest  alkyl substituent chain length (R: C2), [EMIM] Br exhibited the highest extraction efficiency in the oxidative desulfurization of the model  oil; the extraction efficiency of [EMIM] Br was also observed  to  exceed  that  of  acetonitrile.  In  general,  the  oxidative  desulfurization  with  the above [RMIM]Br’s is apparently a more efficient method of thiophene removal from the model oil as compared to a non-oxidative procedure with the same extraction solvents. The extraction efficiency of [RMIM]Br’s was observed to decrease with the lengthening of the alkyl  substituent  chain.  The  same  trend  is  observed  in  the  non-oxidative  extractive desulfurization of the model oil. Recyclability analysis of [EMIM]Br showed that [EMIM]Br can be recycled thrice with no significant decrease in extraction efficiency.

Published: March 2018

Graphene is one of the most promising allotropes of carbon with wide applications in nanotechnology. Modification of graphene by chemical means can further expand its uses. Here, liquid-exfoliated graphene is functionalized with p-aminophenyl moiety using p-nitrophenyl diazonium salts which were diazotized in situ then reduced by tin(II) chloride. The aminophenyl-graphene thus produced is further modified to form polyaniline-graphene (PANI-GNH) by in situ oxidative graft polymerization of aniline using ammonium peroxydisulfate as oxidizing agent. The properties of the PANI-GNH were compared with polyaniline/graphene blends by Raman, infrared and UV-Visible spectroscopy, and cyclic voltammetry. Indeed, PANI-GNH registered different spectrochemical and electrochemical properties compared with the physically blended PANI and GNH, a manifestation of the effect of chemical grafting on the overall property of the modified graphene.

Extraction Methods for Quantifying Iron, Calcium and Magnesium in a Historic Brickwork Produced During the Spanish Colonial Period in the Philippines
Authors: Cayme Jan-Michael C. , Asor Aniano, Jr. N.
Published: March 2018

This study demonstrates the feasibility of performing chemical analyses on heritage materials in the Philippines. Four extraction methods were evaluated based on the percentage of iron, calcium and magnesium in a clay brick sample obtained from an old Spanish colonial period church at Ilocos Norte. Aqua regia (1:3 HNO3:HCl, v/v) solvent was used to extract these elements by conventional hot plate digestion. The extraction methods are: digesting the sample directly with aqua regia (M1), sample pre-digested with NH4Cl and ethyl alcohol prior to the actual digestion (M2) and soaking the sample with aqua regia for 24 hours (M3) and 48 hours (M4) before digestion. Atomic absorption spectroscopy (AAS) was employed to quantify the concentration of the intended elements. The percentage composition of iron ranges from 4.193 to 4.418%, calcium from 0.123 to 0.203%, and magnesium from 2.346 to 2.458%, respectively. Energy-dispersive X-ray spectroscopy (EDX) analysis was done to support the data obtained from AAS. M1 was more effective in extracting calcium from the brick sample, while M2, M3 and M4 were useful for extracting iron and magnesium. Infrared spectroscopy (IR) provided a basic mineralogical composition of the sample, with peaks that were attributed to quartz, kaolinite, calcite, silicates and hematite.
Electrodeposition and Thin Film Formation of Hyperbranched Poly(N-Vinylcarbazole) on Indium-Tin-Oxide Substrates
Authors: Atayde Eduardo, Jr. C. , Arco Susan D.
Published: March 2018

Thin films consisting of carbazole moieties are of current interest due to their various applications in optical and electronic devices.  This study focuses on a new polymeric structure of carbazole and its ability to form films on conductive substrates. Hyperbranched poly(N-vinylcarbazole) (HPVK) was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization in the presence of an initiator monomer, 2-(methacryloyloxy)ethyl, 4-cyano-4 (phenyl carbonothioylthio)pentanoate (CPP-HEMA).  The hyperbranched polymer was then electrodeposited by cyclic voltammetry on indium-tin-oxide (ITO) substrates to afford the electroactive thin films.  The films were analyzed by atomic force microscopy (AFM), UV spectroscopy and ellipsometry.  These data were compared to the ones obtained using linear poly(N-vinylcarbazole) (LPVK).  Effective electrodeposition on ITO substrates was proven by the peak observed at 430 nm in the UV spectrum and by the characteristic anodic and cathodic peaks present in the cyclic voltammogram.  Furthermore, results showed that HPVK produced smoother, more homogeneous and thinner films with film thickness of 10 nm.

Content Analysis of the Discussion of the Atom in General Chemistry Textbooks Using Evaluation Criteria Based on the Nature of Science and Philosophy of Chemistry
Authors: Perez Angelo Julian E. , Guidote Armando, Jr. M. , Yu Gilbert U. , Mariano Michael Ner E.
Published: March 2018

Evaluation criteria are adapted from previous textbook analyses on the nature of science (NOS) in general chemistry textbooks. These criteria are used to determine how certain NOS dimensions are mentioned and elaborated in those textbooks. Such dimensions emphasize that chemistry is (1) tentative, (2) empirical, (3) model-based, (4) inferential, (5) has technological products, (6) employs instrumentation, and (7) possesses social and societal dimensions. Three book chapters were read and evaluated: the first (on chemistry in general); the second (on atomic structure); and the sixth or seventh chapters (on the electronic structure of atoms). The relevant content in each textbook were rated using the following rubric: Satisfactory and Explicit (S, 2 points); Mention and Implicit (M, 1 point); and No Mention (N, 0 point). Silberberg (2009) has the highest score among the six textbooks with 12 points out of the maximum of 14. It was rated S for five criteria, the most among the six textbooks. Despite the presence of some N evaluations, all textbooks have mentioned some or all of the NOS dimensions formulated, resulting to M and S ratings. This study concludes that NOS dimensions are already present in various ways and varying degrees in each textbook.

Cтруктура и термодинамические характеристики примесных центров в оксиде кадмия, допированном литием: первопринципный PAW-подход
Authors: Жуков В.П. , Шеин И.Р.
Published: March 2018

Первопринципным методом присоединенных проекторных волн (PAW) выполнены расчеты электронной структуры оксида кадмия со структурой NaCl, допированного Li. Определена энергия предпочтения атомами Li междоузельной позиции и энергия окисления примеси. Показано, что в условиях термодинамического равновесия стабильной является междоузельная позиция атомов Li, однако присутствие вакансий в кислородной подрешетке способствует появлению атомов Li в позициях замещения атомов Cd. Установлено, что атомы Li в междоузельной позиции и в позиции замещения атомов Cd, атомы Li в позиции замещения и кислородные вакансии, а также пары кислородных вакансий образуют комплексы с минимальным расстоянием между ними. Внедрение атомов Li в междоузельные позиции приводит к существенному уменьшению ширины запрещенной зоны, что объясняет экспериментальное значительное увеличение проводимости.

Mesoporous jarosite/MnO2 and goethite/MnO2 nanocomposites: Synthesis and application for oxidation of methylene blue
Authors: Sabbaghan M. , Adhami F. , Aminnezhad M.
Published: March 2018

Jarosite-MnO2 and goethite-MnO2 nanocomposites are synthesized for the first time via a simple in situ reduction-oxidation process using iron(II) sulfate heptahydrate, potassium permanganate, and sodium hydroxide with cetyltrimethylammonium bromide (CTAB) as a template. The prepared materials are well characterized by different analytical techniques such as X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and surface area studies. The reactivity of these catalysts towards a methylene blue solution is exa­mined. The results indicate that a higher N-demethylation rate of methylene blue (MB) is available under the goethite/MnO2 catalyst to thionin in acidic circum. Also goethite/MnO2 as a heterogeneous Fenton-like catalyst is highly effective for the decolorization and degradation of MB in the presence of H2O2. The degradation efficiency is best (90 % within 60 min) with initial concentrations: 31.25 mg/l of MB, 1.5 ml of hydrogen peroxide, and 0.02 g of goethite/MnO2 as the catalyst. The presence of goethite particles leads to the improvement of the catalytic properties, thus indicating that the catalyst is potentially useful in the treatment of wa­stewater.

Nowadays, important data in the form of word files have been widely used. But there are still few who apply security techniques to the important files. Files that are confidential or important, if they fall into the hands of others may be misused or manipulated for certain purposes. The existence of document security applications built on cryptographic algorithms is one solution to solve the above problems. Cryptographic techniques secure a data or important files by encoding the data into a cipher that is difficult to understand again by others. The RC5 algorithm is one of the cryptographic technique algorithms that can be used to encode text from word files based on the RC5 algorithm so that it can improve the expression of important and confidential word files.

CAUSATIVITY IN THE MIRROR OF COGNITIVE GRAMMAR OF THE ENGLISH CONSTRUCTIONS
Authors: Lepshokova Elizaveta Akhiyaevna , Karasova Svetlana Yakh'yaevna , Tsekova Larisa Mukhamedovna
Published: March 2018

The article investigates the cognitive-semantic features and contexts of functioning of some predicates of the English language. As the contexts of these predicates functioning the authors consider a system of movement causation with the predicates of object-space direction, force, speech (verbal) and psychological influence, as well as the predicates of movement with adverbial semantics. The construction of movement causation covers all linguistic expressions, corresponding to its matrix semantic-syntactic scheme and implemented within a conventional script of causative-directive (complex) process.

На основе конъюгата хитозана с фолиевой кислотой получены гидрогелевые частицы, содержащие до 49 масс. % иматиниба метансульфоната (мезилата). Исследована кинетика его высвобождения из частиц в растворах, моделирующих физиологические среды человеческого организма. Установлено, что кинетические закономерности высвобождения метансульфоната иматиниба из частиц конъюгата хитозана с фолиевой кислотой описываются моделями Корсмейера — Пеппаса и обратной степенной функции от времени. Показано, что регулировать скорость высвобождения иматиниба из гидрогелевых частиц можно изменением содержания фолиевой кислоты в конъюгате.
