Penelitian dilaksanakan pada Maret - Desember 2011 dengan metode survei. Jumlah responden 54 orang peserta SL-PTT di Kabupaten Bangka dan Kabupaten Bangka Selatan. Tingkat adopsi petani terhadap komponen PTT dianalisis secara deskriptif, sedangkan faktor-faktor yang mempengaruhinya dianalisis dengan menggunakan model regresi logit. Hasil penelitian menunjukkan bahwa (1). komponen PTT yang tingkat adopsinya tinggi yaitu varietas unggul, penanganan panen dan pascapanen, tanam bibit muda dan cara pengolahan lahan sesuai musim; (2). faktor-faktor sosial ekonomi yang menjadi penentu bagi petani dalam mengadopsi PTT padi sawah yaitu pendidikan, luas lahan, jarak pemukiman ke usahatani padi, jalan raya, pasar input, dan sumber teknologi.
METODOLOGI AREA FRAME UNTUK PENGUKURAN PRODUKTIVITAS PADI
Authors: Chafid Mohammad
Published: February 2018

Informasi tentang data produksi diperoleh dari pengumpulan data luas panen dan produktivitas. Pengumpulan data produktivitas padi dengan pendekatan rumah tangga yang dilakukan sering dianggap kurang representatif. Pusdatin mengembangkan dan melakukan uji coba metodologi area frame untuk pengukuran produktivitas padi yang bertujuan untuk menghitung rata-rata hasil produktivitas padi dan membandingkan dengan hasil pengukuran produktivitas padi melalui survei ubinan reguler. Metode yang digunakan adalah penarikan contoh acak sistematik.

Faktor yang mempengaruhi program peningkatan produktivitas padi, yaitu sampel untuk ubinan jatuh pada dataran rendah/tinggi dan adanya program SL-PTT/tidak ada program SL-PTT. Survei dilakukan di Kabupaten Cianjur dan diperoleh hasil 90 petak jatuh pada dataran tinggi dan 310 petak pada dataran rendah. 56 petak mengikuti program SLPTT dn 344 petak tidak mengikuti program SLPTT dengan jumlah sampel 400 petak. Hasil uji perbandingan ratarata berat ubinan metode Area Frame dan Listing Frame berdasarkan kecamatan menunjukkan hasil nilai p-value di 12 kecamatan atau sebanyak 75% tolak Ho, yang berarti terdapat perbedaan signifikan antara ubinan metode area frame dan listing frame . Sedangkan berdasarkan pada wilayah kabupaten menunjukkan nilai p-value 0,493 (terima Ho), yang berarti tidak terdapat perbedaan yang signifikan antara ubinan metode area frame dan ubinan listing frame . Hal ini menunjukkan bahwa keragaman hasil ubinan padi di dalam kecamatan lebih tinggi dari pada pada keragaman hasil ubinan seluruh wilayah kabupaten.

Metode area frame memiliki keuntungan lebih, yaitu lokasi ubinan yang jelas karena dipetakkan dengan cermat sehingga tidak akan bergeser di luar mesh yang terpilih.

Probabilistic Data-Driven Prediction of Wellbore Signatures in High-Dimensional Data Using Bayesian Networks
Authors: Bassamzadeh Nastaran , Ghanem Roger
Published: February 2018

Accurate, data-driven, stochastic models for fluid-flow prediction in hydrocarbon reservoirs are of particular interest to reservoir engineers. Being computationally less costly than conventional physical simulations, such predictive models can serve as rapid-risk-assessment tools. In this research, we seek to probabilistically predict the oil-production rate at locations where limited data are observed using the available data at other spatial points in the oil field. To do so, we use the Bayesian network (BN), which is a modeling framework for capturing dependencies between uncertain variables in a high-dimensional system. The model is applied to a real data set from the Gulf of Mexico (GOM) and it is shown that BN is able to predict the production rate with 86% accuracy. The results are compared with neural-network and co-Kriging methods. Moreover, BN structure enables us to select the most-relevant variables for prediction, and thus we managed to reduce the input dimension from 36 to 17 variables while preserving the same prediction accuracy. Similarly, we use the local-linear-embedding (LLE) method as a feature-extraction tool to nonlinearly reduce the input dimension from 36 to 10 variables with negligible loss in accuracy. Accordingly, we claim that BN is a valuable modeling tool that can be efficiently used for probabilistic prediction and dimension reduction in the oil industry.
Energía Azul: generación de potencia a través de la Ósmosis por Presión Retardada (PRO)
Authors: Aristizabal Alzate Carlos Esteban
Published: February 2018

La emisión de gases efecto invernadero, tales como el CO2, causadas por el uso de combustibles fósiles y el crecimiento exponencial de la población mundial, han volcado los esfuerzos del hombre hacia la búsqueda de fuentes de energía limpia y sostenible, que satisfagan las necesidades energéticas actuales y las futuras. Por lo que se volvió una prioridad investigar y desarrollar tecnologías que aprovechen las energías renovables, una de ellas es la Ósmosis por Presión Retardada (PRO), el cual es un proceso o método de generación de energía eléctrica, que aprovecha el gradiente de salinidad entre dos soluciones, ya que la mezcla de una solución salina de concentración alta con agua fresca, disipa más de 2,2 MJ energía libre por m3 de agua dulce tratada. A escala industrial, se podría aprovechar la diferencia de concentración de sales entre los ríos y el mar, cerca de una zona conocida como estuario. La aplicación, viabilidad y eficiencia del proceso y la tecnología que funciona bajo este fenómeno, dependen de las características de la membrana semipermeable, como la potencia por unidad de área, y las propiedades físicas, químicas y de superficie de esta. En la actualidad se utilizan membranas de acetato de celulosa, las cuales dan potencias muy bajas (1W/m2). Sin embargo, se está investigando con membranas de materiales compuestos, como por ejemplo las basadas en grafeno, las cuales permiten un mayor flujo de agua a través de la membrana y potencias superiores a 5 W/m2.
Bacterial Protein Mimetic of Peptide Hormone as a New Class of Protein- based Drugs
Authors: Fetissov Sergueï O. , Legrand Romain , Lucas Nicolas
Published: February 2018

Specific peptide molecules classified as hormones, neuropeptides and cytokines
are involved in intercellular signaling regulating various physiological processes in all
organs and tissues. This justifies the peptidergic signaling as an attractive pharmacological
target. Recently, a protein mimetic of a peptide hormone has been identified in Escherichia
coli suggesting the potential use of specific bacterial proteins as a new type of
peptide-like drugs. We review the scientific rational and technological approaches leading
to the identification of the E. coli caseinolytic protease B (ClpB) homologue protein as a
conformational mimetic of α-melanocyte-stimulating hormone (α-MSH), a melanocortin
peptide critically involved in the regulation of energy homeostasis in humans and animals.
Theoretical and experimental backgrounds for the validation of bacterial ClpB as a
potential drug are discussed based on the known E. coli ClpB amino acid sequence homology
with α-MSH. Using in silico analysis, we show that other protein sources containing
similar to E. coli ClpB α-MSH-like epitopes with potential biological activity may exist
in Enterobacteriaceae and in some Brassicaceae. Thus, the original approach leading
to the identification of E. coli ClpB as an α-MSH mimetic protein can be applied for the
identification of mimetic proteins of other peptide hormones and development of a new
type of peptide-like protein-based drugs.

Published: February 2018

The objective of the work is to identify the most preeminent elements of resilience in the face of disability at the Technical University of Manabí. To do this, a wide-ranging exploration and bibliographical study was carried out, which allowed us to return to the criteria addressed by several authors recognized internationally in the study of resilience and especially those of the Latin American area. The work deals with contemporary contextual aspects that may be favorable to the psychosocial approach to resilience. The article is based on research based on the qualitative interpretative paradigm. The theoretical referents were consigned from the bibliographic review, to compare them with the empirical phase that allowed interpreting the individual representations of disabled youth about resilience. The results of the research show that resilience is widely known, although an important bias is maintained in its representation related to a more individual than the social view, which could limit its influence as a pedagogical factor.

The Effects of Task-Based Process Writing Approach on the Academic Writing Skills among Second Language Tertiary Learners
Authors: Johari Siti Katijah
Published: February 2018

Academic writing occupies a very important place in the English language syllabus at tertiary level. Where higher institution writing is concerned, it is not enough that students have to write in traditional essay or report formats; their writing must be appropriate to the discipline – yet deal with the multitude of genres expected of them. Additionally, academic writing skill is considered an essential skill for academic success and a requirement for many occupations and professions. However, it is a skill that a number of second language tertiary students find most difficult to acquire and only a few of them fully master it. This study, therefore, embarks on the theory that task-based approach together with the exposure of process writing would have a significant influence on the development of students’ academic writing skills. In this study students were made to work in groups on real-life tasks which relate to their field of study or future employment. In the midst of pursuing the group project, the students will have to write their group proposal and individual writing assignment. This will be the stage where the process writing techniques are put into practice. This paper will illustrate an eclectic pedagogic intervention in the teaching of academic writing skills to second language tertiary students.

Appealing to different motivations in a message to recruit citizen scientists: results of a field experiment
Authors: Lee Tae Kyoung , Crowston Kevin , Harandi Mahboobeh , Østerlund Carsten , Miller Grant
Published: February 2018

This study examines the relative efficacy of citizen science recruitment messages appealing to four motivations that were derived from previous research on motives for participation in citizen-science projects. We report on an experiment (N=36,513) that compared the response to email messages designed to appeal to these four motives for participation. We found that the messages appealing to the possibility of contributing to science and learning about science attracted more attention than did one about helping scientists but that one about helping scientists generated more initial contributions. Overall, the message about contributing to science resulted in the largest volume of contributions and joining a community, the lowest. The results should be informative to those managing citizen-science projects.

Authors: Peresypkina Anna , Gubareva Victoria , Levkova Elena , Shabelnikova Anna , Pokrovskii Mikhail
Published: February 2018

Introduction/Objective. The objective of this paper was to increase the effectiveness of pharmacological correction of retinal ischemia-reperfusion by using minoxidil. Methods. The research was carried out on 180 Wistar rats. A modification of the retinal ischemia-reperfusion model was used, in which an increase in intraocular pressure is carried out by mechanical pressure (110 mmHg) to the front chamber of the eye for 30 minutes. Protective effects of minoxidil at a dose 0.5 mg/kg on the model of retinal ischemia-reperfusion were estimated by the changes in the level of retinal microcirculation (laser Doppler flowmetry), electroretinogram amplitude, morphometry of retinal layers after 1 hour and 72 hours of reperfusion. Results. Minoxidil at a dose 0.5 mg/kg of rat mass improves retinal microcirculation, its electrophysiological state after 1 hour and 72 hours of reperfusion, and prevents the development of degenerative changes in the retina caused by ischemic damage to a greater extent than recombinant erythropoietin at a dose of 50 IU/kg and sildenafil at a dose of 0.5 mg/kg in monotherapy. The protective effects of minoxidil were eliminated by the preliminary administration of glibenclamide at a dose of 5 mg/kg, which indicates the presence of the preconditioning effect of minoxidil, realized through adenosine triphosphate-dependent potassium channels. Conclusion. Minoxidil at a dose of 0.5 mg/kg of rat mass protects the retina from ischemic-reperfusion injury. Protective effects of minoxidil are carried out by a preconditioning action, as evidenced by the lack of positive effects with the administration of glibenclamide.
Dr Avram Farkic (1866-1925), the founder and the owner of the first physical therapy institute in Serbia
Authors: Jovanovic-Simic Jelena
Published: February 2018

Methods of physical medicine, many of which have been empirically applied since the ancient times, have become particularly popular in 19th century Europe. The first examples of the works of Serbian doctors in this area originate from the same period. In 1838 and 1839, Dr. Konstantin Peicic wrote about Prissnitz?s method of hydrotherapy. In 1842, Dr. Dimitrije Radulovic published in Latin his doctoral dissertation concerning medical gymnastics. In the middle of the 19th century, in the Principality of Serbia, hydrotherapy treatments (by Dr. Andrija Ivanovic, 1850) and electrotherapy (by Dr. Jovan Valenta, 1857) w?re applied. Among the pioneers of physical medicine in Serbia, Dr Avram Farkic is a very important figure. In 1896, Farkic founded the first Serbian institute for physiotherapy in Belgrade, and, two years later, the First Institute for Orthopedics, Swedish Gymnastics and Massage. These institutions were merged in 1899. After the death of Dr. Farkic in 1925, the Institute worked under his name until the German bombing of Belgrade on April 6, 1941. The diversity and continuous introduction of modern therapeutic procedures were the main characteristics of the Institute during its 45-year-long existence. Dr. Farkic was also the initiator of the establishment of the Therapy Joint Stock Company, which founded the first institute for physical medicine in Vrnjacka Banja, the Therapy Institute for Treatment by Water and Electricity, in 1911. Until the First World War, it was the most modern spa sanatorium in Serbia. During spa seasons of 1911, 1912, 1913, and 1924, Dr. Farkic himself was the manager and the main physician of the Therapy Institute.

Published: February 2018

Over the course of several decades at the Faculty of Medicine in Novi Sad, fundamental studies in the field of neurosciences were of great importance and were continually kept up-to-date with global scientific achievements. These studies were applied by using the stereotactic method, single-unit recording, and electroencephalography. The Laboratory of Neurophysiology was established in 1965 and since 1978 microelectrode and microiontophoretic techniques important for the registration and analysis of the activity of individual neurons were fully developed. Under the great influence of Russian neurophysiological school (P.K. Anokhin, K.V. Sudakov), the emphasis was on the study of Anokhin?s theory of functional systems. Recently, epilepsy, brain ischemia and the influence of different medications, auxiliary medicinal products, and physical agents (electromagnetic radiation) on the central nervous system, behaviour, learning and investigated pathological conditions have been studied. Scientific collaboration with renowned institutions in the country and abroad has been established, numerous scientific projects have been carried out, expert international meetings have been organized, and numerous significant studies have been published. These results have often been the basis for further clinical investigations and the improvement of preventive or curative treatment of patients. Researchers from the Laboratory participated in the education of new generations of neurophysiologists, encouraging their scientific curiosity and love for fascinating mechanisms of the nervous system.

Published: February 2018

Introduction. Analysis of canine lipoprotein fractions after agarose gel electrophoresis (agEF) separation could be an important diagnostic tool in primary and secondary dyslipidemia diagnosis. The aim of this study was to measure concentrations of triglycerides and cholesterol and to analyze lipoprotein fractions in dogs after basal (12 hours) and short-term (24 and 36 hours) fasting, i.e., frequent conditions in clinical practice. Materials and Methods. Blood samples were collected from six lean dogs of both sexes and different breeds, after 12, 24 and 36 hours of fasting. Concentrations of glucose, triglycerides and cholesterol were determined on an automated wet biochemistry analyzer, lipoprotein fractions were separated by agEF and leukocyte numbers were assessed on an automated hematology analyzer. Results and Conclusions. Results showed there was no significant change in glucose, triglyceride and cholesterol concentrations nor in leukocyte numbers during dog fasting. Moreover, there was no change in ?1- and ?2-fractions, but there was a significant decrease in pre?- and ?-fraction of lipoproteins. It is know that high density lipoproteins (HDL) have ?-mobility and very low density (VLDL) and low density lipoproteins (LDL) have pre?- and ?-mobility. Thus, it is possible that reverse cholesterol transport maintained by HDL is not affected during short-term fasting. On the contrary, synthesis of VLDL and formation of LDL are probably decreased because endogenous synthesis of triglycerides is decreased or their clearance is increased.

Estudio de valores personales y adaptación al medio entre estudiantes de diseño industrial y diseño gráfico / Study of personal values and adaptation to the environment among students of industrial design and graphic design
Authors: Reyes Fabela Ana María
Published: February 2018

En este artículo se abordó un estudio exploratorio de valores personales de los estudiantes de las licenciaturas en Diseño Industrial y Diseño Gráfico de la Universidad Autónoma del Estado de México. El propósito fue conocer los valores que los estudiantes asignan a la formación profesional elegida. Se partió del supuesto de que existe una escala distinta de valores por parte de los estudiantes; dependiendo de la licenciatura se conforma una escala diferente, porque son distintas las expectativas y las maneras de adaptarse al medio.Para la investigación se propuso estudiar dos carreras que están dentro de una misma área: el diseño. Sin embargo, cada una tiene perfiles distintos. El diseño industrial, orientado a la creación de objetos, procesos y sistemas, es proclive a las innovaciones conforme cambia la industria. El diseño gráfico es sensible a los cambios digitales y sus formas. Las características de ambas carreras determina la ponderación de los valores por parte de los estudiantes de cada una de estas licenciaturas. Se aplicó el Estudio de Valores con una escala para la medición de los intereses dominantes de la personalidad (Allport, Vernon y Lindzey, 2001) a una muestra de 201 estudiantes (77 de Diseño Industrial y 124 de Diseño Gráfico).

This research aims to explore the students’ writing and critical thinking capacity in a joint construction practice in an academic writing course. The course applied a genre-based approach in teaching academic writing and critical thinking to first-year English as a Foreign Language students of a private university in Pontianak, West Kalimantan, Indonesia. A combination of explicit teaching, group discussion, and online review sessions was employed in the joint construction practice for three meetings. The source for the data collection was a jointly constructed text. The text was selected from thirty-six students who worked in groups. Every group consisted of low achievers, medium achievers, and high achievers in writing. The text was analyzed using functional grammar. The analysis shows that the students had gained a good control of the exposition genre with its linguistic features. Thematic progression and logical connectors at the text level and circumstances (adverbs) at the clause level had realized critical thinking skills and dispositions. Several grammatical mistakes and improper lexical choices were identified but did not interfere with the purpose of the text. The findings suggest that having more classroom meetings will make explicit teaching and group discussion work effectively before the students begin to write independently. Moreover, online review sessions can support the students' learning but with limitations.

The findings of this study overall proved that the implementation of this learner-centered teaching framework could make a difference in students’ learning. Their learning became more meaningful, interesting and democratic. Apart from this positive change, it was identified that teacher’s understanding of implementing this framework was still limited resulting in the inconsistency of implementing all aspects of learner centered teaching approach. This study could highlight issues unique to the context of this research but were not covered in the framework. It, therefore, produced an extended framework.

Permasalahan AIDS (Acquired Immuno Deficiency Virus) berkembang

dengan cepat dan menjadi sebuah ancaman kesehatan dunia yang utama.

Salah satu layanan terhadap pemberian informasi seputar HIV/AIDS adalah

melalui VCT (Voluntary Counseling Testing). Adanya diskriminasi

terhadap HIV/AIDS ini membuat keikutsertaan seseorang mengikuti VCT

(Voluntary Counseling Testing) atau tes konseling sukarela bagi seseorang

yang ingin mengetahui status HIV nya mungkin rendah akibat takut

mendapat diskriminasi. Bagi seseorang yang akan menjalankan tes, muncul

berbagai reaksi emosi seperti cemas dan takut, terutama ketika mengetahui

hasil yang diperoleh positif.. Kemampuan seorang individu untuk dapat

menyesuaikan diri dengan stressor yang dialaminya itulah yang disebut

dengan coping stress. Hipotesis penelitian adalah ada hubungan yang

negatif antara coping stres dengan kecemasan. Artinya semakin baik coping

stres maka semakin rendah kecemasan dan sebaliknya. Teknik analisa data

yang dipakai dalam penelitian ini adalah analisa kuantitatif non parametrik:
