A Simplified Method for Estimating Atomic Number and Neutrons Numbers of Elements Based on Period and Group Numbers in the Periodic Table
Authors: H. M. Al-Ossmi Laith
Published: February 2019

This research has proposed formulas, in which the atomic number and neutron numbers to any element in the periodic table are determined according to element position in the periodic table. These formulas have been arranged to fit with periodic system of elements in the IUPAC's Periodic Table. The main outcome is to introduce layout regularity, which may reflect the regularity of the periodic law more faithfully. In this research, atomic number to any element in the periodic table is predictably calculated by the group and period numbers which were displayed into 7 Periods horizontally, and 18 Groups vertically, determining and dispensing altogether the elements positions at the periodic system. Application of these proposed formulas showed linearity from has good agreement with these separated elements of Lanthanum in the f-block elements (Lanthanides and Actinides), which were in no interruptions in the sequence of increasing atomic numbers. In addition, the relationship of the f-block to the other blocks of the periodic table also becomes easier to see. In addition, the formulas are extensible to expanding future table and allowed determining the atomic number of the future elements starting from 119 till the element of 136, at the main body of the periodic table, and can be used as a simple and alternative method for determine the numbers of atomic and neutron in the IUPAC's Periodic Table.

The constantly increasing growth in the number of cars is one of the reasons for the deterioration of the ecological situation in cities and large settlements. In Kazakhstan, on a national scale, the share of motor vehicles in total emissions of pollutants into the atmosphere by all technogenic sources reaches on average 40%, in the mass of industrial waste - 2%. The content of toxic substances in the exhaust of diesel and gasoline engines varies and depends on the type of engine and mode of operation, as well as on the quality of the fuel, the composition of the combustible mixture in the engine cylinders, speed and driving conditions, ignition system and fuel control. The number of all toxic components in the exhaust gas exceeds the maximum permissible standards by tens and hundreds of times. One of the most reliable ways to reduce the toxicity of vehicle exhaust gases and remove harmful substances is the complete oxidation of exhaust components using catalytic compositions on metal or ceramic block carriers. The article accumulates data from the scientific literature about toxicity of different components of exhaust gases and catalytic neutralization of vehicle exhaust gases by various scientific schools.

Preparation of Linear Low-density Polyethylene/Treated Date Palm Leaflet Green Composites and Investigation of their Thermal and Mechanical Properties
Authors: Alshabanat Mashael
Published: February 2019

This work aims to develop green linear low-density polyethylene (LLDPE) composites that are commercially viable due to the low cost of the date palm leaflet filler, which is a local renewable resource. The filler was naturally treated with gum arabic solution. FT-IR, XRD, and SEM techniques were used to characterize the samples. The thermal and mechanical properties were measured by TGA, DSC, and tensile testing. The results showed noticeable changes in the properties of the composites compared to those of the original LLDPE sample. TGA revealed that the composite started thermally. The composites started thermally degrading before the original polymer, owing to the degradation of the natural components in the filler. The findings from DSC suggested that the crystallinity was affected. The tensile testing results indicated that the composites were appropriate for applications requiring low tensile strength at break and high Young’s modulus. A comparison of these results with earlier ones exhibited that the basic additives in the polymer may have an effect on the filler performance.

The experiment was conducted to determine the organ weight characteristics, carcass yield and cost benefits of Kano Brown goats fed cassava root sievate and cassava leaf meal (CRSCLM) based diets as supplement to (Pennisetum  purpureum) using 36 Kano Brown goats of 8 to 10 months of age.Four diets T1, T2, T3,and T4, were formulated at the levels of 0%, 20%, 40% and 60% CRSCLM respectivelyin a completely randomized design. Each animal received a designated treatment diet in the morning for 97 days. Feed offered was based on 3.5% body weight per day; the animals in addition were fed a kg wilted chopped P. purpureum later in the day as basal diet to enhance rumination and fine chewing. Results on  carcass indices showed significant (p<0.05) response on live weight at slaughter, empty carcass weight, warm carcass weight, dressing percentage, shoulder, leg, loin, end and shank with T4having relatively best results. The dressing percentage was numerically (49.59%) best at T4. On the offal weights, head and full guts were significantly (p<0.05) improved for T4and T1goats. The organ characteristic proved the safety of using CRSCLM through the significantly (p<0.05) lower organ weights at T4goats. Cost per kg feed, feed cost/weight gainand cost/benefit ratio were positively influenced (p<0.05) at T4with expected income of 4.79 / 1 invested. It could therefore be concluded that Kano Brown goats fed 60% CRSCLM had the best carcass and organ yields at a reduced feed cost. Keywords: Pennisetum purpureum, Kano brown goats, Cassava leaf meal, Cassava root sievate,

Applicability of NBO and AIM Topology Analyses to Chemical Bonding in Some Diacetylplatinum(II) Complexes
Authors: Soliman Saied M. , Zaid Mohamed M.
Published: February 2019

The geometrical structures of six square-planar diacetylplatinum(II) complexes ([Pt(Ac)2L], L = hydrazine-type ligand) were calculated using six (B3LYP, CAM-B3LYP, B3PW91, M06, M06HF and PBE) DFT methods and one post-Hartree–Fock (MP2) method combined with 6-31G(d,p) basis sets for nonmetal atoms and LANL2DZ for Pt. Using percent relative errors, M06HF and MP2 are best for predicting Pt–N bond distances, but worst for Pt–C bond distances, whereas B3PW91 is best. Pt–N(pyridine) bonds have higher electron density at the bond critical points than Pt–N(hydrazone) bonds, and the former are more covalent than the latter. Further, Pt–C bonds trans to hydrazone moieties are more covalent than Pt–C bonds trans to Pt–N(pyridine) bonds. Pt–C bonds are mainly due to Pt→Ac back donation rather than Ac→Pt donation; σ-bonding is less important in this case, consistent with the high π-acidity and strong trans effect of acetyl groups. In contrast, Pt→N back donation is negligible and Pt–N bonds are mainly due to N→Pt σ-donation, which stabilizes trans Pt–C bonds.

Authors: Kumar Sanjay , Saya L. , Tandon H.C. , Gulati Shikha
Published: February 2019

The absorption and fluorescence characteristics of two biologically active flavone derivatives 6-hydroxy-7,3’,4’,5’-tetramethoxyflavone (6HTMF) and 7-hydroxy-6,3’,4’,5’-tetramethoxyflavone (7HTMF) were studied as a function of acidity (pH/H0) of the solution. Dissociation constants were determined for ground and first excited singlet states and the results were compared with those obtained from Forster-Weller calculations. The acidity constants for these two compounds (6HTMF and 7HTMF) obtained from fluorimetric titrations are in poor agreement with those obtained from Forster-Weller data but are in good agreement with ground state pKa values indicated the deactivation of excited state (S1) before the prototropic equilibrium is complete. The broad band emission of both the flavones in acidic aqueous solution suggests their use as tuneable dye lasers. 6-Hydroxy-7,3’,4’,5’-tetramethoxyflavone undergoes adiabatic photo-dissociation in the singlet excited state indicating the formation of an exciplex or a photo-tautomer. The stability of photo-tautomer was confirmed by calculated value of enthalpy of formation using AM1 method.
"Una mancha en el sol de Euclides": Hilbert y la teoría euclídea de las proporciones
Authors: Giovannini Eduardo N.
Published: February 2019

El artículo examina una de las contribuciones más importantes a los fundamentos de la geometría euclídea elemental lograda por David Hilbert en su obra Fundamentos de la geometría (1899), a saber: la reconstrucción de la teoría euclídea de las proporciones y de los triángulos semejantes. Se argumenta que dicha reconstrucción no sólo estuvo motivada por la identificación de Hilbert de suposiciones implícitas en la teoría de Euclides, sino que además estuvo esencialmente ligada a la preocupación por la 'pureza del método'. Más aún, se afirma que, en este caso específico, el requerimiento de Hilbert por la pureza del método posee un carácter general o fundacional, esto es, no se refiere a la demostración de un teorema en particular, sino más bien es planteado respecto de la construcción axiomática de la teoría misma.

Así también, en algún sentido, la anticipación de su Lógica posterior. El artículo tiene como propósito dedicar algunas meditaciones básicas al origen de esta obra en relación con los cursos del período de Jena, la posible transformación conceptual de la Fenomenología durante el tiempo de su redacción y su contribución a la Ciencia de la lógica posterior.
Giro pragmático y teoría política. Un análisis desde la democracia deliberativa
Authors: Prono Santiago
Published: February 2019

La relación entre pragmatismo y teoría política viene siendo explorada de diversas maneras en numerosos trabajos que analizan el tema. La idea es explicitar qué recepción lleva a cabo la filosofía política de los presupuestos del pragmatismo. En este contexto, en el presente trabajo se analiza el tema desde la democracia deliberativa de J. Habermas, señalando de qué modo esta teoría política recepta tales presupuestos teniendo en cuenta el marco teórico del discurso argumentativo, que constituye la base filosófica sobre la cual fundamenta su estructura teórica. Como resultado de este análisis es posible señalar (parte de) las contribuciones de aquella teoría política para el mejoramiento de la calidad democrática del estado de derecho.
¿En qué sentido es la Lógica de Hegel el dinero del espíritu? Interpretación del sistema hegeliano desde la génesis del dinero en El capital de Marx
Authors: Castiglioni Germán D.
Published: February 2019

Es sabido que las obras de Marx, en sus distintas épocas, guardan siempre una relación conflictiva con Hegel. Pero, al mismo tiempo, esta relación se ve afectada continuamente por el propio desarrollo del pensamiento de Marx. Teniendo en cuenta este desarrollo, en el presente trabajo intentaremos brindar una interpretación marxiana del sistema hegeliano, tomando como punto de partida la frase juvenil de Marx que afirma que la Ciencia de la lógica de Hegel es "el dinero del espíritu". Sin embargo, bajo la premisa de que Marx está mucho más próximo a Hegel en su período de madurez que en su juventud, daremos un nuevo sentido a aquella frase juvenil a partir del tratamiento del dinero en la primera sección de El capital. Esto nos proporcionará nuevas herramientas conceptuales para interpretar la filosofía de Hegel, justificando esta interpretación en los propios textos hegelianos.
La verdad del poder y el poder de la verdad en los cursos de Michel Foucault
Authors: Castro Edgardo
Published: February 2019

Este artículo se ocupa de las relaciones entre poder y verdad en los cursos de Michel Foucault. Busca mostrar cómo se ha pasado de una concepción en la que se insistía en las instancias de poder como productoras de discursos verdad al análisis de la fuerza de la propia verdad como límite del poder. En este contexto, luego de haberse ocupado de la introducción de la idea de voluntad en la arqueología de saber y sus consecuencias, aborda las nociones de régimen de verdad y veridicción.
El régimen semántico de la afectividad en Sein und Zeit. Una interpretación semiótica de M. Heidegger
Authors: Bertorello Adrián
Published: February 2019

La diferencia semántica entre la disposición afectiva y la comprensión en Sein und Zeit radica en que el sentido inherente a la afectividad es del orden de lo continuo. En cambio, el sentido de la comprensión es del orden de lo discreto. El régimen de lo continuo se caracteriza por ser un campo de fuerzas que organiza el sentido de acuerdo a una continuidad gradiente. El régimen de lo discreto, por el contrario, organiza el sentido de acuerdo a una articulación de unidades significativas pragmáticas diferenciables que no se identifican con el lenguaje. De esta manera lo continuo y lo discreto puede ser reinterpretado como la fuerza y el significado. Así, entonces, el sentido de la disposición afectiva y el de la comprensión se distinguen por pertenecer a regímenes semánticos distintos. Los afectos pertenecen al dominio de la fuerza y la comprensión pertenece al campo del significado (Bedeutung).

Narrativas civilizatorias de la enseñanza de las matemáticas: lo que se mantiene, irrumpe y se transforma y el sujeto
Authors: Guerrero Recalde Néstor Fernando
Published: February 2019

En el presente artículo se muestran los resultados del proyecto de investigación doctoral “Narrativas civilizatorias de la enseñanza de las matemáticas en Colombia”. El estudio tuvo como propósito comprender, a partir de narrativas de profesores, las razones que han situado a la enseñanza de las matemáticas como un saber para el progreso en Colombia.  Para el análisis de las narrativas de los profesores se empleó la metodología de investigación narrativa propuesta por Quintero (2017). Su carácter hermenéutico-interpretativo reconoce el carácter contextual, inductivo y semántico de la narrativa histórica. Los resultados de esta investigación contribuyen a la reflexión sobre cómo el proceso civilizatorio de la enseñanza de la matemáticas occidentales convirtió a los saberes matemáticos en saberes hegemónicos, subordinando al sujeto a los modelos económicos neoliberales. Frente a esta postura se levanta como alternativa la humanización del conocimiento hacia el cuidado del Otro y de lo otro, en el reconocimiento del pluralismo y de la diversidad de culturas. En las conclusiones del estudio se señala que: en primera instancia, con la enseñanza de las matemáticas se pone en evidencia que la formación que se ha privilegiado en los futuros licenciados, desde la década de 1970 sigue siendo la de las matemáticas modernas. En segundo lugar, que en resistencia al movimiento de las matemáticas modernas irrumpen la perspectiva sociopolítica de la educación matemática. Finalmente, se concluye que a nivel de la formación inicial y continua de los profesores se están dando transformaciones sobre su práctica profesional.

Published: February 2019

Tujuan dari penelitian ini adalah untuk mengetahui kebutuhan informasi kepala keluarga Pria dan Wanita dan mengetahui perbedaan-perbedaan yang ada serta untuk mengetahui bagaimana alur kepala keluarga dalam menelusur informasi, sumber-sumber apa yang digunakan, dan waktu penelusuran informasi. Penelitian ini menggunakan metode penelitian kualitatif. Sedangkan untuk mengumpulkan data menggunakan metode observasi dan wawancara, untuk mendapatkan data yang sedalam-dalamnya dari informan. Hasil penelitian ini kebutuhan informasi kepala keluarga pada dasarnya hampir sama dengan kebutuhan informasi manusia pada umumnya. Informasi tesebut seperti informasi pekerjaan, hobi, kuliner, berita, serta informasi lainya, tidak hanya informasi untuk kepentingan pribadi, namun juga informasi lain yang dibutuhkan terutama oleh anak mereka, seperti informasi megenai hobi, dan informasi untuk menyelesaikan tugas sekolah. Sumber informasi utama dari internet dan media sosial. Antara seorang kepala keluarga Pria yang membina keluarga yang utuh dan wanita yang menjadi orang tua tunggal, hampir terlihat adanya perbedaan dalam pemenuhan kebutuhan informasi. Seorang kepala keluarga yang normal lebih terlihat lebih mampu memanajemen kebutuhan informasi dirinya dan keluarganya, sementara orang tua tunggal terlihat kesulitan. Sebagai contoh untuk memenuhi informasi anak, pria dari keluarga yang utuh mampu membimbing dan mengajari anaknya ketika menelusur informasi di internet, berkerjasama dengan istrinya. Sementara wanita yang menjadi orang tua tunggal kurang mampu mengajari anaknya bagaiman cara menggunakan internet untuk menelusur informasi, sehingga meminta bantuan orang lain. Kami berasumsi pada keluarga normal beban hidup dan tanggung jawab dalam mengurus anak lebih ringan, dari pada pria atau wanita yang menjadi orang tua tunggal. Dalam keluarga normal setiap masalah dihadapi antar suami-istri saling bekerjasama. Sementara orang tua tunggal bekerja sendiri untuk memenuhi kebuhutan hidup dan mendidik buah hati yang dimiliki.

Minimum Noise Fraction (MNF) is known as one of the method to minimize noise on hyperspectral imagery. In addition, there are not many studies have tried to show the effect of MNF transform on multispectral data. This study purposes to determine the effect of MNF transform on the accuracy level of vegetation density modeling using 10 meters Sentinel-2A spatial resolution (multispectral data) and to know the cause. The study area is located in parts of Sapporo City, Hokkaido, Japan. Vegetation density is modelled through vegetation index approach, Normalized Difference Vegetation Index (NDVI). The results show that the coefficient correlation of vegetation density data and vegetation index regression after MNF transformation (0.801623) has higher value than the same regression without the MNF (0.794481). However, better correlation does not represent the better accuracy on vegetation density modeling. Accuracy calculation through standard error of estimate shows the use of MNF in multispectral data for vegetation density modeling causes the decrease of model accuracy value. The accuracy of vegetation density model without involving MNF transformation reached 91.40 %, while the model accuracy through MNF transformation before vegetation density modeling reached 90.89 %. The insignificant increased accuracy is occurred due to the limited number of multispectral image information compared to hyperspectral image data.
DEUS VERSUS OHIRUME DALAM CERPEN KAMIGAMI NO BISHOU: BENTURAN BUDAYA ANTARA BARAT DENGAN JEPANG

Published: February 2019

(Title: Deus Versus Ohirume in Kamigami No Bishou: Cultural Clash Between West and Japan) The Kamigami no Bishou short story is one of the most famous Japanese literary works, Akutagawa Ryuunosuke. Kamigami no Bishou was created by Akutagawa in 1922 which tells the meeting of Organtino, a Christian missionary in Japan with an old man who was the embodiment of one of Japan's ancient gods. The purpose of this article is to reveal how the clash of cultures between the West and Japan was reconstructed in Kamigami no Bishou short stories. To achieve this goal, the following steps are taken. First, an explanation of the terms contained in the Kamigami no Bishou Short Story. Second, explained the actions of two figures in the short story that are in opposition to the Greimas model's official scheme because this scheme can make it easier to understand the actions and motivations of the characters. Third, the analysis of one of the short story structural elements is a theme with the aim of understanding the essence and purpose of the entire short story. Fourth, further explanation about the reconstruction of Western versus Japanese cultural clash which is explained by the presentation of binary opposition. After going through all four stages, it was concluded that the reconstruction of cultural clash in Kamigami no Bishou short stories was presented by Akutagawa in a conversation between the Organtino character and the old male character. Through a dialogue centered on Deus versus Ohirume carried out by Organtino figures and old male figures, Akutagawa indirectly wanted to convey the message that Japanese tradition and culture would not be destroyed due to influences from foreign cultures that entered.

Children with intellectual disability (ID) have deficit in their adaptive functions, such as self-care in practical domain. The skill of self-care in moderate ID children can develop after being trained, although it takes a long time. One of skills that can be developed is urination skill. Urination skill is important to teach on children with ID so they can maintain their genital organs health independently. Therefore, interventions related to urination skill using behavior modification program with total task presentation technique are required. The purpose of this research is to evaluate the effectiveness of total task presentation technique to increase urination skill on child with moderate ID. This study used a single case subject A-B design that used to find changes in scores by comparing behavior observation data of participant’s urination skill and make a data analysis. Participant in this study was a 10 years old boy who has deficit in urination skill. After the implementation of the intervention program in 16 sessions for 14 days with 81 trials, it was found that the total task presentation technique is effective to improve urination skill on a child with moderate ID. The participants has been able to take control the entire range of urinating behavior (22 chain of behaviors) independently. Previously, the child could only controlled the nine chain of behaviors independently.

Research on emotional regulation has been dominated by a hedonist perspective, which argued that the existence of positive affects and the absence of negative affects is an indicator of optimal human functioning. Meeting hedonic needs, however, is not the only goal of emotional regulation. Emotional regulation can also facilitate the integrity of the personality-oriented function as a whole. Mindfulness as an emotional regulation strategy is escorted by attention to all that is taking place in the present moment with an attitude of acceptance, thereby facilitating person-oriented function by bringing emotional experiences towards neutrality. The effectiveness of brief induction of mindfulness in comparison with other strategies in Gross and Thompson’s (2007) Process Model of Emotion Regulation (i.e., reappraisal, distraction, suppression) and control condition was tested in this randomized-mixed design experiment (N = 260) through self-reported ratings of affective valence for 60 positive, neutral, and negative photographs. The effectiveness of mindfulness was equivalent to positive reappraisal for positive stimulus, but lower than positive reappraisal for negative stimulus. Suppression consistently demonstrated equality of effectiveness with mindfulness, while distraction was as equally ineffective as control condition. These complex dynamics of emotional responding between mindfulness and other emotional regulation strategies requires further exploration.

Small islands are often promoted as a tourism destination in spite of the limited fresh water resources availability that they could retain for daily needs. In this context, efforts to provide fresh water resources sustainable in the small island are necessary to support the tourism destination purpose. This study aims to estimate the carrying capacity of the fresh water resources in Pari Island. The estimation method is the ratio between the fresh water availability and its demand by calculating the island size, aquifer thickness, annual rainfall, hydraulic conductivity or soil permeability, and the application of rainwater harvesting technology (RHT). The result shows that the carrying capacity of the fresh water resources without technological intervention in Pari Island is 2.05. Even though this score indicates the safe level, the measure has not taken the water quality into consideration yet. Expectedly, it could be improved by applying the RHT technology but it results in the carrying capacity score of 1.37 and 1.47 (conditionally safe) for the current state and 25-year future prediction respectively. This study recommends the improvements in tourism management by limiting the visitor number in order to support their sustainability for the local livelihood and Pari Island’s ecosystem conservation.
