Hydrolysis of Metal Ions from the Perspective of Proton Transport in Liquid Water
Authors: Lim Len Herald V.
Published: March 2018

The  dynamics  of  proton  transfer  reactions  still  persists  as  an  open  question  to  both experimentalists  and  theoreticians.  Theoretical  studies  on  liquid  water  indicate  that  the molecular  processes  involved  occur  at  timescales  transparent  to  conventional  detection.  In contemporary  models,  the  anomalous  diffusion  of  a  proton  in  liquid  water  appears  to  be closely  tied  to  how  hydrogen  bonding  patterns  evolve,  which  suggests  that  proton dissociation  proceed  only  if  certain  conditions  are  met:  structural  patterns  and  dynamics satisfied  over  a  network of hydrogen  bonded  molecules.  These  have  been  verified  through simulations of highly charged metal ions in aqueous solution in which quantum mechanical calculations  are  explicitly  invoked  to  allow  the  occurrence  of  hydrolytic  events. The  results obtained thereof have given insight into the proper evaluation of proton transfer events and how they can be understood in the context of many body interactions.
Sampling and Analysis of Petroleum Coco-Biodiesel Blend-Fueled PUV Exhaust for NO2 and Particulate PAH, Elemental Composition and Toxicity
Authors: Ramos Carina S. , Hachero April Anne B. , Hallare Arnold V. , Rubio Raquel , Quirit Leni L.
Published: March 2018

The polycyclic aromatic hydrocarbon (PAH), elemental composition and toxicity of particulate matter from the exhaust of public utility vehicles (PUVs) fueled by commercial petroleum coco-biodiesel blend, were examined and compared with that from the exhaust of PUVs fueled by unblended petroleum diesel. FAME (Fatty Acid Methyl Ester) analysis of the commercial diesel/biodiesel blend and of a pure biodiesel sample was done to ascertain the presence of biodiesel in the commercial blend. NO2 from the exhaust vapor phase was likewise also compared for the two types of fuel. PAHs in particulate matter obtained by filter sampling and from tailpipe soot were analyzed by GC-MS (gas chromatography mass spectrometry). NO2 was analyzed by visible spectrophotometry, XRF (x-ray fluorescence spectrometry) was used for elemental analysis, and toxicological analysis was done using the Zebrafish Egg Assay Test. A general tentative conclusion from the results point to minimal difference between pure diesel and the 1% diesel/biodiesel blend (when used as fuel for PUVs) in terms of engine exhaust impact on air quality, except perhaps for PAH levels to some extent.

Chitosan and Quat-188 Modified Chitosan Poly(acrylic acid) Semi-Interpenetrating Network For Controlled Release of Drugs
Authors: Gonzales Christian , Leal Mari Kaira O. , Andalis Ivy Marie C. , Chua Modesto T. , Nakaoki Takahiko , Chakraborty Soma
Published: March 2018

Semi-interpenetrating polymer networks (semi-IPNs) composed of polyacrylic acid (PAA), and chitosan or N-(3-chloro-2-hydroxypropyl)trimethylammonium chloride (Quat-188) modified chitosan were synthesized. To fabricate the semi-IPN, acrylic acid (AA) was polymerized and crosslinked in the presence of unmodified and Quat-188 modified chitosan. The wet strength of the semi-IPNs improved with the increase in molecular weight of chitosan, chitosan to PAA ratio and by Quat-188 modification. Both modified and unmodified semi-IPNs swelled in buffer solutions. Swelling was pH dependent. The mode of encapsulation and release of two different types of drugs from these semi IPNs was studied. Effects of various parameters on encapsulation and release of AgNO3 and mafenide acetate from these semi-IPNs were investigated. The semi-IPN hydrogel encapsulated 10 mmol/L AgNO3 (100% of added drug) in 5min and released 4% of it in 2h. In case of mafenide acetate, pH dependent encapsulation and controlled release was observed. It was observed that drug-semi IPN interaction strongly influences the encapsulation and release behavior. Freezable water associated with the hydrogels also played an important role for the encapsulation and release of drug.

Authors: Flores Annabelle C. , Punzalan Eric R. , Ambangan Norberto G.
Published: March 2018

Food packaging materials derived from renewable sources are highly sought due to their low cost and wide range of functional properties. This research reports on the fabrication and physico-chemical properties of composite films from cassava starch and κ-carrageenan.Characterization of the films by FTIR indicates physical entanglements between polymer chains. The water solubility of the films showed linear dependency on the κ-carrageenan content while the moisture content diminished with the addition of κ-carrageenan. . The mechanical property of the films showed that as the amount of κ-carrageenan increases, tensile strength exhibited improvement, the water activity (aw) increased, and pH became more basic, while % elongation weakened. Water vapour transmission rate (WVTR) improved significantly from 82.73 g/(m2.day) for pure thermoplastic starch to 11.31 g/(m2.day) for 90/10 % (w/w) starch/ κ-carrageenan ratio, which is comparable to WVTR of commercial polypropylene.
Preliminary Study on Deltamethrin Residues in Cabbage, Soil and Water from Dalaguete, Cebu, Philippines
Authors: Calinawan Amstrong , Mendoza Concepcion S. , Adarna Leonila
Published: March 2018

Pesticides pose a threat to the environment and eventually human health. Extent of contamination of pesticides can be determined and monitored by analysis of pesticide residue in surface water, sediments, soil, and biota. Samples were collected from Manlapay, Barangay Mantalongon in Dalaguete, reportedly the vegetable basket of Cebu, from October to November 2013. Concentration of the pesticide deltamethrin was determined by Gas Chromatography-Electron Capture Detector along with organic matter content (OM), potassium (K) and cation exchange capacity (CEC) using standard methods of analysis. Data showed that deltamethrin was found to be present in soil and cabbage and beyond detection limit in water. Inverse relationship was found between residue in cabbage and in soil confirming pesticide leaching as supported by rainfall data. Organic matter and cation exchange capacity in soil showed significant correlation to detected deltamethrin residue confirming that pyrethroids are strongly bound to organic matter and free exchangeable potassium ions. Deltamethrin residue in water does not show any correlation to any other parameters as it is beyond detection limit, probably due to volatilization and photodegradation of deltamethrin in water. Temperature variation does not show significant difference to deltamethrin residue in all three matrices. The detected deltamethrin residue concentrations in the cabbage (<0.001-0.029 ppm), soil samples (0.007-0.008 ppm) and water samples (<0.0005 ppm) were all below international guideline limits (ASEAN maximum level of 0.5 ppm deltamethrin in cabbage, EC ecologically accepted concentration of 1290 mg deltamethrin/kg soil, and a maximum limit of 0.0025 ppm deltamethrin according to Canadian water quality, respectively). Inspite of the low concentrations detected in cabbage, soil and water samples, an extensive pesticide monitoring on environmental samples within the area is advisable.  This will help the adoption of an efficient risk assessment strategy to inform appropriate interventions.

Assessing In-service Teachers’ Chemistry Content Knowledge and Self-efficacy in Teaching the K to 12 Science Curriculum
Authors: Mongcal Yna Camille A. , Lee-Chua Queena N. , Guidote Armando, Jr. M.
Published: March 2018

As the K to 12 Science program was formally implemented, interventions to enhance competence and confidence of teachers in teaching science in a spiral progression approach are main concerns. This study aims to assess the chemistry content knowledge and self-efficacy of 38 in-service teachers enrolled in a graduate program from a teacher education institution using a content knowledge test (CKT) and a self-efficacy beliefs scale (SeS) using a mixed-method approach. Quantitative findings reveal that the least mastered topics in chemistry of the teacher-respondents include solutions, chemical bonding, the mole concept, gas laws, and chemical reactions. The science teachers say they are “somewhat confident” in teaching the chemistry topics. Qualitative findings include difficulties in answering the CKT and challenges encountered in teaching chemistry using the K to 12 science curriculum. In the needs analysis, key findings in the results of focus group discussion are used to verify quantitative findings. The correlation between content knowledge and self-efficacy beliefs is r = -0.12, with findings showing a negligible to low correlation. This implies that even if teachers perceive that they are “somewhat confident” in teaching chemistry topics, such beliefs do not match their content knowledge scores. Valid findings are based on the CKT results and further suggest that the CKT (not the SeS) is a good measure in determining the content learning needs of teachers.
Coconut Oil: Bringing History, Common Sense and Science Together
Authors: Dayrit Fabian M.
Published: March 2018

The modern Western diet has suffered the damaging effects of trans fats, much of it from soybean oil. It is suffering another blow, this time from the damaging effects of an excess of omega-6 fats, again from soybean oil.

The vast majority of epidemiological studies do not distinguish between coconut oil and animal fat, and simply refer to them collectively as “saturated fat.” This is a fatal mistake for two reasons: first, the fatty acid profiles of coconut oil and animal fat are very different, and second, coconut oil hardly has any cholesterol while animal fats contain a lot of cholesterol. This means that the results based on animal fat cannot be applied to coconut oil.

Contrary to the claim of the AHA, there is abundant evidence to show that coconut oil and a coconut diet do not raise the incidence of heart disease and are, in fact, part of many healthy traditional diets. Many populations who shifted from a traditional coconut diet to a Western diet have suffered worse health outcomes. However, the historical and scientific evidence in support of coconut oil may not be enough to convince the AHA which favors a high omega-6 diet.

A theoretical study of hydrotreatment of the oxolane molecule without a catalyst and in the presence of a catalyst is performed by numerical DFT/B3LYP methods with 6-31G(d) and LanL2DZ basis sets. The catalyst used in this study is tungsten disulfide (WS2) which is mo­deled by a three anionic vacancy site WS3H3+. Hydrogenolysis of the oxolane molecule under hydrogen pressure is simulated through two sequential stages. The temperature and pressure experimental conditions taken in account in the study were 523, 573, and 623 K under 40 bar. The analysis of variations of diverse system parameters during the process reveals that oxolane undergoes a C—O bonds cleavage at a ring opening at the end of both hydrogenolysis pro­cesses. The first hydrogenolysis process leads to the formation of a butan-1-ol molecule, which then undergoes second hydrogenolysis under the same pressure and temperature conditions. Finally, second hydrogenolysis produces water and butane molecules.
Solvent effect on equilibrium and rate constant of the tautomeric reaction in Nexium, Skelaxin, Aldara and Efavirenz drugs: A DFT study
Authors: Sargolzaei M. , Afshar M. , Nikoofard H.
Published: March 2018

Some drugs have two tautomeric structures in the liquid state and the tautomeric equilibrium is formed between these structures. The reaction rate and equilibrium constant of this reaction varies in different solvents. Thus, the determination of the appropriate solvent to separate tautomers is important. In this research, we used the DFT level of B3LYP and the 6-311++G** basis set to obtain the proper solvent for Nexium, Skelaxin, Aldara and Efavirenz drugs. All calculations were made above the melting point of the mentioned drugs, because these drugs are solid at room temperature. The solvent effect is included in the calculation utilizing the polarizable continuum model PCM. The transition state of the tautomeric reaction is determined using the quadratic synchronous transit (QST2) method. The geometry, energy, and dipole moment of transition states are analyzed in different solvent. The root mean square deviation (RMSD) analysis is performed to determine the degree of a structure deviation of tautomer 1 and tautomer 2 from the transition state in different solvents. It is found that the RMSD value for tatumer1 is higher than that for tautomer 2 in all studied drugs. The proper solvent for the separation of tautomers is determined from the analysis of thermodynamics and kinetics.

Published: March 2018

Проведено полноатомное молекулярно-динамическое моделирование и анализ водных растворов природных осмолитов: триметиламиноксида (ТМАО), мочевины и их смеси при относительно малых (биологически релевантных) концентрациях. Недавно в работе (Smolin N. et al. PCCP. 2017. 19. P. 6345) было отмечено, что в гидратной оболочке белка доля молекул ТМАО существенно ниже, чем мочевины. При этом добавление мочевины приводит к дальнейшему понижению доли ТМАО в гидратной оболочке белка. В данной работе показано, что в двойных растворах в окрестности молекул мочевины всегда наблюдается повышенная доля мочевины по сравнению с концентрацией в объеме. В то же время доля ТМАО вблизи ТМАО такая же, как в объеме. В тройных растворах ТМАО и мочевина ведут себя так же, как в двойных, т.е. они не оказывают заметного взаимного влияния друг на друга. Это означает, что поведение молекул ТМАО и мочевины в гидратной оболочке белка связано с белком, а не с их взаимодействием друг с другом.

Structural and textural modifications of ZrO2 induced by La2O3 addition, thermal treatment and reducing process

Published: March 2018

Lanthana-doped zirconium oxide may strongly influence the solid state reaction. A series of samples denoted ZrxLa1–x (where x = atomic percentage of the element) are prepared by hydrolysis in the neutral medium from ZrO2 and La2O3. These samples are calcined under air at 450, 900, and 1200 °C, then characterized by specific surface area (BET), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermoreductions programmed under H2 (TPR—H2). The results show that after calcination at 450 °C, the lanthanum addition increases slightly the zirconia surface area and the XRD analysis does not reveal any interaction between two oxides. After calcination at 900 °C, sintering appears and oxides lose half of their surface area. Lanthanum is not inserted into the structure of ZrO2, while some interaction occurs between lanthanum and zirconium oxide. At 1200 °C, the sintering of the samples is very important; the specific surface is about 1 m2/g; XRD results show that ZrxLa1–x are formed basically by three mixed oxides: La2Zr2O7, La0.5Zr0.5O1.75, La0.46Zr0.54O1.77, which is confirmed by the SEM method. H2-TPR experiments confirm that changes in the reducibility can reflect some alterations of the nature of interactions between ZrO2 and La2O3. Preliminary experiments on zirconia do not reveal the occurrence of significant reduction processes. On the other hand, extensive reduction of La2O3 is much more accentuated for lanthana samples. At high temperatures, a significant lessening in the H2 consumption suggests that ZrO2 would likely interact with La2O3, which is confirmed in the results indicating the presence of the pyrochlore type of oxides mentioned above.
Declarative approaches for Compliance by Design

Published: March 2018

The interest of scholars in devising automated methods to describe and analyse business processes is increasing in the last decades due to the extreme interest of organisations in achieving their business objective while remaining compliant with the relevant normative system. Adhering with the relative normative system does not only avoid to incur in severe sanctions but results in greater confidence by the consumers and prestige for the organisation. Defining processes through the paradigm declarative specifications is gaining momentum due to its intrinsic characteristic of being able to capture business as well as normative specifications within the same framework. We describe some of the state of the art techniques in the field of Business Process Compliance, focusing on pros and cons and advancing future lines of research.
Crashing simulated planes is cheap: Can simulation detect robotics bugs early?
Authors: Timperley Christopher Steven , Afzal Afsoon , Katz Deborah , Hernandez Jam Marcos , Le Goues Claire
Published: March 2018

Robotics and autonomy systems are becoming increasingly important, moving from specialised factory domains to increasingly general and consumer-focused applications. As such systems grow ubiquitous, there is a commensurate need to protect against potentially-catastrophic harm. System-level testing in simulation is a particularly promising approach for assuring robotics systems, allowing for more extensive testing in realistic scenarios and seeking bugs that may not manifest at the unit-level. Ideally, such testing could find critical bugs well before expensive field-testing is required. However, simulations can only model coarse environmental abstractions, contributing to a common perception that robotics bugs can only be found in live deployment. To address this gap, we conduct an empirical study on bugs that have been fixed in the widely-used, open-source ArduPilot system. We identify bug-fixing commits by exploiting commenting conventions in the version-control history. We provide a quantitative and qualitative evaluation of the bugs, focusing on characterising how the bugs are triggered and how they can be detected, with a goal of identifying how they can be best identified in simulation, well before field testing. To our surprise, we find that the majority of bugs manifest under simple conditions that can be easily reproduced in software-based simulation. Conversely, we find that system configurations and forms of input play an important role in triggering bugs. We use these results to inform a novel framework for testing for these and other bugs in simulation, consistently and reproducibly. These contributions can inform the construction of techniques for automated testing of robotics systems, with the goal of finding bugs early and cheaply, without incurring the costs of physically testing for bugs in live systems.

Osmanlı
Devleti’ne Prusya’dan ilk defa III. Selim döneminde askeri görevliler
gelmiştir. Bu süreç II. Abdülhamid dönemine kadar sürmüştür. Prusya’da II.
Wilhelm’in tahta geçişinden sonra Osmanlı Devleti ile ilişkiler daha da
yoğunlaşmıştır. 1877-1878 Osmanlı-Rus savaşından sonra özellikle askeri
konularda Almanya’dan fazlasıyla faydalanılmıştır. Osmanlı Devleti, Almanya’dan
subay getirttiği gibi kendisi de Almanya’ya eğitim için subay göndermiştir. Bu
dönemde Almanya’dan gönderilen Kamphövener, Von Hobe, Ristov ve özellikle Von
Der Goltz Osmanlı ordusu üzerinde çok etki bırakmıştır. Bu yüzden II. Meşruiyet
döneminde de Osmanlı subayları Alman ordu yapısını örnek almaya devam etmiş ve
Alman subaylarına büyük saygı göstermişlerdir. Bu çalışmada II. Meşrutiyet döneminde
Almanlara olan hayranlığın basındaki yansımalarına Asker Mecmuası üzerinden
bakılmış ve incelenmiştir. Asker Mecmuası’ndaki özellikle Von Der Goltz
hakkındaki düşünceler dikkat çekicidir.

Rendahnya hasil belajar siswa mata pelajaran Jaringan Dasar siswa kelas X TKJ 1 SMKN 1 Bangkinang menjadi latar belakang penelitan tindakan kelas ini. Peneliti merasakan proses belajar mengajar masih terpusat kepada guru, materi sering tersajikan dalam bentuk ceramah dan demonstrasi sehingga sering peneliti menjumpai siswa lebih banyak diam dan mendengarkan saja, kreatifitas dan kemandiriannya kurang terwujud dan proses belajar mengajarpun tidak berjalan sebagaimana yang diharapkan. Hal ini menjadi penyebab hasil belajar siswa turun. Dari 36 siswa hanya ada 20 orang siswa yang nilainya berada di atas kriteria ketuntasan minimal (KKM) atau sekitar 55% dan tentunya tidak sesuai dengan yang diharapkan. Untuk itu Peneliti merasa perlu mengatasi permasalahan belajar ini dengan melakukan penelitian tindakan kelas. Penelitian tindakan kelas yang peneliti lakukan berjudul “Meningkatkan Hasil Belajar Jaringan Dasar Model Pembelajaran Berbasis Proyek (Project Based Learning) Siswa Kelas X TKJ 1 SMKN 1 Bangkinang”. Dengan adanya penelitian ini  Peneliti berharap dapat menemukan jalan keluar untuk mengatasi permasalahan belajar, dan semoga kedepannya hasil bejar siswa dapat ditingkatkan. Penelitian Tindakan Kelas (PTK) ini dilakukan dalam dua siklus dan teknik pengumpulan data yang digunakan adalah data dari hasil ujian kompetensi pada kompetensi Dasar.

Mobil teknolojinin gelişmesi ve mobil araçların reklam kanalları
içerisinde kullanılmasıyla birlikte, firmaların kaliteli hizmet sunma ve
müşteri memnuniyeti sağlama üzerine yaptıkları çalışmalar da gelişme
göstermiştir. Bir yandan teknoloji gelişirken diğer yandan tüketicilerin istek,
ihtiyaç ve beklentileri de değişime uğramıştır. Tüketiciler artık en kaliteli
ve kendilerini en çok memnun edecek ürün ve hizmetleri elde etmek için çaba
sarf etmektedir. Günümüzün rekabet şartları tüketicilere zaman ve mekân sınırı
olmadan ulaşılmasını gerektirmektedir. Mobil araçların tüketicilere doğrudan,
mekân ve zaman sınırı olmadan ulaşılmasını mümkün kılan bir yol olduğu
düşünüldüğünde, firmaların bu reklam kanalını pazarlama etiği çerçevesinde
etkin ve verimli bir şekilde kullanmaları hem daha kaliteli hizmet sunabilme
hem de müşteri memnuniyeti sağlayabilme yolunda fırsatlar sunmaktadır. Bu
çalışmada, mobil reklamcılıkta müşteri memnuniyeti ile bireysel müşteri hizmet
kalitesi ve algılanan müşteri memnuniyeti değişkenleri arasındaki ilişkiler
değerlendirilmiştir. Bireysel müşteri hizmet kalitesi ve algılanan müşteri
memnuniyeti değişkenlerinin, mobil reklamcılıkta müşteri memnuniyeti ile
ilişkisini belirleyebilmek amacıyla Facebook, Twitter ve Linkedin kullanıcıları

Phytochemistry, antibacterial and anticoagulase activities of Sida acuta against clinical isolates of Staphylococcus aureus
Authors: Essien J. P. , Antia B. S. , Ebong G. A.
Published: March 2018

The phytochemical, antibacterial and anticoagulase activities of Sida acuta against clinical isolates of Staphylococcus aureus were investigated. The phytochemistry of the plant leaves revealed that S. acuta is laden with antioxidative compounds with remarkable concentrations of saponins (0.772 mg/100g), flavonoids (0.112 mg/100g), alkaloids (0.076 mg/100g) and tannins (0.0541mg/100g). Their presence conferred a strong bactericidal effect on Staphylococcus aureus SS-1VC, Staph. aureus SS-2VM, Staph. aureus SS-3SW, Staph aureus SS-4OM, Staph. aureus SS-5BC Staph. aureus SS-6AF and Staph. aureus SS-7DS isolated from vaginal candidiosis, vaginal mycosis, septic wound, otitis media, buccal cavity, athletes foot and diarrheic stool respectively. Majority of the bacterium strains screened were sensitive to aqueous and methanol extracts of S. acuta leaves. All the strains were inhibited by the aqueous extract, but more susceptible were strains SS-2VM isolated from vaginal mycoses and SS-3SW from septic wound, which recorded 25mm and 24mm diameter of inhibition zones respectively, after treatment with 8.0mg/ml of the extract. However, much lower concentration (0.5mg/ml) of the extract was required to halt coagulase activity in both strains. The methanol leaf extract exhibited similar but stronger antibacterial and anticoagulase activities against the clinical isolates of Staph. aureus. Marked antibacterial inhibitory effects were observed against most strains tested but SS-6AF and SS-7DS (which exhibited comparatively lower susceptibility), with majority of the strains losing theiranticoagulase producing potential at concentrations as low as 0.5mg/ml of alcoholic extract. The strong anticoagulase activity of S.acuta, and it’s efficacy in inhibiting coagulase elaboration by Staph aureus especially Staph. aureus SS3SW isolated from septic wound forms the basis of it’s use in folk medicine for wound treatment.
