The paper discusses the requirements for the system of remote sensing (hereinafter referred to as “System”) which is focused on the end user (EU), based on the concepts of object-oriented monitoring. The classification of simple queries generated with interactive tools in the context of the end user’s subject area is presented. The research investigates the features of the System needed for maintaining task-setting interaction, such as the subject ontology, including knowledge about the object of interest, its static and dynamic properties, the hierarchy of vector layers that describe spatial objects, the updated image database. The authors indicate the resources necessary for solving specific tasks, including spatial data repository and specification of computational procedures capable of interpreting the query in terms of decision operators. Specifically, the paper considers the structure of task-setting interaction tools, which ensures the object space-time localization, finding its meaning in semantic space, performance specification parameters measured one time or in dynamics, requirements for the visualization of the results and the activity of the System in relation to the end user in the monitoring process. The solutions presented were tested on monitoring the condition of agricultural lands in the multi-task space monitoring system of the Institute of Space and Information Technology, Siberian Federal University, Krasnoyarsk.

A procedure for constructing a digital elevation model (DEM) of the northern part of the Volga-Akhtuba interfluve is described. The basis of our DEM is the elevation matrix of Shuttle Radar Topography Mission (SRTM) for which we carried out the refinement and updating of spatial data using satellite imagery, GPS data, depth measurements of the River Volga and River Akhtuba stream beds. The most important source of high-altitude data for the Volga-Akhtuba floodplain (VAF) can be the results of observations of the coastlines dynamics of small reservoirs (lakes, eriks, small channels) arising in the process of spring flooding and disappearing during lowflow periods. A set of digitized coastlines at different times of flooding can significantly improve the quality of the DEM. The method of constructing a digital elevation model includes an iterative procedure that uses the results of morphostructural analysis of the DEM and the numerical hydrodynamic simulations of the VAF flooding based on the shallow water model.

In this paper, we consider the solution of the problem of increasing the speed of the algorithm for hyperspectral images (HSI) compression, based on recognition methods. Two methods are proposed to reduce the computational complexity of a lossy compression algorithm. The first method is based on the use of compression results obtained with other parameters, including those of the recognition method. The second method is based on adaptive partitioning of hyperspectral image pixels into clusters and calculating the estimates of similarity only with the templates of one of the subsets. Theoretical and practical estimates of the increase in the speed of the compression algorithm are obtained.

Authors: Ekonomiuk Dariusz , Kielbasinski Marcin , Kolinski Andrzej
Published: November 2019

A high resolution reduced model of proteins is used in Monte Carlo dynamics studies of the folding mechanism of a small globular protein, the B1 immunoglobulin-binding domain of streptococcal protein G. It is shown that in order to reproduce the physics of the folding transition, the united atom based model requires a set of knowledge-based potentials mimicking the short-range conformational propensities and protein-like chain stiffness, a model of directional and cooperative hydrogen bonds, and properly designed knowledge-based potentials of the long-range interactions between the side groups. The folding of the model protein is cooperative and very fast. In a single trajectory, a number of folding/unfolding cycles were observed. Typically, the folding process is initiated by assembly of a native-like structure of the C-terminal hairpin. In the next stage the rest of the four-ribbon beta-sheet folds. The slowest step of this pathway is the assembly of the central helix on the scaffold of the beta-sheet.

The inhibitory effect of numerous analogues of PO-16, an hexadecadeoxyribonucleotide antisense to sequences -22 to -17 of PAI-1 mRNA coding for a fragment of the signal peptide, on the expression of PAI-1 in endothelial cells, and physiological consequences of the subsequently reduced PAI-1 activity tested in vitro and in vivo, were described in our previous studies. Of particular interest was PO-16 5'-O-conjugated with menthyl phosphorothioate (MPO-16R). In this work, tissue localisation of MPO-16R labelled with [(35)S] phosphorothioate at the 3'-end, was determined. [(35)S]MPO-16R and control [(35)S]MPO-16R-SENSE oligonucleotides were administered intravenously into 22 rats and organ distribution of the labelled bioconjugates was assessed after 24 and 48 h. For this purpose, tissue sections were subjected to autoradiography, and quantitated by liquid scintillation after solubilisation. Overall clearance of radioactivity was already seen after 24 h, with the radioactivity recovered mainly in the kidney and liver. A smaller fraction of radioactivity was also retained in the spleen and heart. The kidney concentration of the labelled probe was higher than that of liver by 50%. The distribution of PAI-1 mRNA in untreated rat kidney, liver, spleen and heart established by two independent techniques: Ribonuclease Protection Assay and Real-Time PCR, shows the same pattern as that observed for [(35)S]MPO-16R antisense.

Authors: Jaśkiewicz Ewa , Jedynak Anna , Zioło Ewa
Published: November 2019

MBP and PLP are major structural protein components of myelin. Both proteins play a functional role in formation of myelin sheath and in maintenance of its compaction. Immune responses to MBP and PLP have been implicated in the pathogenesis of multiple sclerosis (MS), an auto-immune disease of the central nervous system. Recombinant forms of both proteins isolated and purified from bacterial or insect cell systems are commonly used to study the specificity of auto-response in MS. We have prepared recombinant forms of MBP and PLP stably expressed in CHO cells. Several clones with proper cytoplasmic MBP or surface PLP localization were obtained and characterized by flow cytometry and indirect immunostaining. CHO cells expressing the recombinant forms of MBP and PLP can be very useful in studies on the autoimmune mechanism of MS.

Published: November 2019

In this work we studied the relationship between the enhanced expression of DR5 receptor and the effect of combination of TRAIL and ionizing radiation on cell cycle arrest and apoptosis induction in human leukemia cell line HL-60.
DR5, APO2.7 and cell cycle were analyzed by flow cytometry. Proteins Bid and Mcl-1 were analyzed by Western-blotting. For clonogenic survival, colony assay on methylcellulose was used.
Ionizing radiation caused significantly enhanced positivity of DR5 receptors 24 h after irradiation with high doses (6 and 8 Gy). An increase of DR5 receptor positivity after a dose of 2 Gy was not statistically significant and application of TRAIL 48 h after irradiation did not increase the apoptosis induction. However, a decrease of radiation-induced G(2) phase arrest and an increase of apoptosis were observed when TRAIL was applied 16 h before irradiation with the dose of 2 Gy. Incubation with 6 microg/l TRAIL for 16 h reduced D(0) value from 2.9 Gy to 1.5 Gy. The induction of apoptosis by TRAIL was accompanied by Bid cleavage and a decrease of antiapoptotic Mcl-1 16 h after incubation with TRAIL.
TRAIL in concentration of 6 microg/l applied 16 h before irradiation by the dose of 1.5 Gy caused the death of 63% of clonogenic tumor cells, similarly as the dose of 2.9 Gy alone, which is in good correlation with the enhanced apoptosis induction.
Regulatory mechanisms of gene expression: complexity with elements of deterministic chaos.
Authors: Jura Jolanta , Wegrzyn Paulina , Jura Jacek , Koj Aleksander
Published: November 2019

Linear models based on proportionality between variables have been commonly applied in biology and medicine but in many cases they do not describe correctly the complex relationships of living organisms and now are being replaced by nonlinear theories of deterministic chaos. Recent advances in molecular biology and genome sequencing may lead to a simplistic view that all life processes in a cell, or in the whole organism, are strictly and in a linear fashion controlled by genes. In reality, the existing phenotype arises from a complex interaction of the genome and various environmental factors. Regulation of gene expression in the animal organism occurs at the level of epigenetic DNA modification, RNA transcription, mRNA translation, and many additional alterations of nascent proteins. The process of transcription is highly complicated and includes hundreds of transcription factors, enhancers and silencers, as well as various species of low molecular mass RNAs. In addition, alternative splicing or mRNA editing can generate a family of polypeptides from a single gene. Rearrangement of coding DNA sequences during somatic recombination is the source of great variability in the structure of immunoglobulins and some other proteins. The process of rearrangement of immunoglobulin genes, or such phenomena as parental imprinting of some genes, appear to occur in a random fashion. Therefore, it seems that the mechanism of genetic information flow from DNA to mature proteins does not fit the category of linear relationship based on simple reductionism or hard determinism but would be probably better described by nonlinear models, such as deterministic chaos.
Free energy of helix propagation in short polyalanine chains determined from peptide growth simulations of La3+-binding model peptides. Comparison with experimental data.
Authors: Maciejczyk Maciej , Hermans Jan , Bierzyński Andrzej
Published: November 2019

Molecular dynamics (MD) is, at present, a unique tool making it possible to study, at the atomic level, conformational transitions in peptides and proteins. Nevertheless, because MD calculations are always based on a more or less approximate physical model, using a set of approximate parameters, their reliability must be tested by comparison with experimental data. Unfortunately, it is very difficult to find a peptide system in which conformational transitions can be studied both experimentally and using MD simulations so that a direct comparison of the results obtained in both ways could be made. Such a system, containing a rigid alpha-helix nucleus stabilized by La(3+) coordination to a 12-residue sequence taken from an EF-hand protein has recently been used to determine experimentally the helix propagation parameters in very short polyalanine segments (Goch et al. (2003) Biochemistry 42: 6840-6847). The same parameters were calculated here for the same peptide system using the peptide growth simulation method with, alternatively, charmm 22 and cedar potential energy functions. The calculated free energies of the helix-coil transition are about two times too large for cedar and even three times too large for charmm 22, as compared with the experimental values. We suggest that these discrepancies have their origin in the incorrect representation of unfolded peptide backbone in solution by the molecular mechanics force fields.
Denatured proteins and early folding intermediates simulated in a reduced conformational space.

Published: November 2019

Conformations of globular proteins in the denatured state were studied using a high-resolution lattice model of proteins and Monte Carlo dynamics. The model assumes a united-atom and high-coordination lattice representation of the polypeptide conformational space. The force field of the model mimics the short-range protein-like conformational stiffness, hydrophobic interactions of the side chains and the main-chain hydrogen bonds. Two types of approximations for the short-range interactions were compared: simple statistical potentials and knowledge-based protein-specific potentials derived from the sequence-structure compatibility of short fragments of protein chains. Model proteins in the denatured state are relatively compact, although the majority of the sampled conformations are globally different from the native fold. At the same time short protein fragments are mostly native-like. Thus, the denatured state of the model proteins has several features of the molten globule state observed experimentally. Statistical potentials induce native-like conformational propensities in the denatured state, especially for the fragments located in the core of folded proteins. Knowledge-based protein-specific potentials increase only slightly the level of similarity to the native conformations, in spite of their qualitatively higher specificity in the native structures. For a few cases, where fairly accurate experimental data exist, the simulation results are in semiquantitative agreement with the physical picture revealed by the experiments. This shows that the model studied in this work could be used efficiently in computational studies of protein dynamics in the denatured state, and consequently for studies of protein folding pathways, i.e. not only for the modeling of folded structures, as it was shown in previous studies. The results of the present studies also provide a new insight into the explanation of the Levinthal's paradox.

Published: November 2019

hnRNP K protein, which localizes to the nucleus, cytoplasm and mitochondria, is involved in the various cellular processes that compose gene expression. We used a SAGE-based assay to profile RNAs associated with hnRNP K protein in rat mitochondria. RNA was isolated from mitoplasts obtained from highly purified and RNase-treated mitochondria. Total RNA and RNA associated with hnRNP K protein were then used as input material for generating two SAGE libraries. Mitochondrion-derived tags isolated from the total mitoplast RNA library represented 86.3%, while those isolated from the library constructed from RNA associated with hnRNP K protein represented only 28.2% of selected tags. Thus, an unexpected number of nuclear-encoded RNAs were purified from mitochondria. Many of these transcripts were co-purified with hnRNP K protein, and high levels of nuclear-encoded RNAs co-immunoprecipitating with K protein corresponded to elevated hnRNP K protein levels of the organelle. The most abundant RNAs that were co-purified with hnRNP K protein represented transcripts originating from satellite I DNA. While satellite I RNA levels were higher in the nucleus and cytoplasm than in mitochondria, the most abundant binding of satellite I transcripts to hnRNP K protein was found in mitochondria. The role of satellite I RNA in mitochondria remains to be elucidated.

Authors: Jazowiecka-Rakus Joanna , Jarosz Magdalena , Szala Stanisław
Published: November 2019

Angiogenesis, i.e. formation of new blood vessels out of pre-existing capillaries, is essential to the development of tumour vasculature. The discovery of specific antiangiogenic inhibitors has important therapeutic implications for the development of novel cancer treatments. Vasostatin, the N-terminal domain of calreticulin, is a potent endogenous inhibitor of angiogenesis and tumour growth. In our study, using B16(F10) murine melanoma model and electroporation we attempted intramuscular transfer of human vasostatin gene. The gene therapy was combined with antiangiogenic drug dosing schedule of a known chemotherapeutic (cyclophosphamide). The combination of vasostatin gene therapy and cyclophosphamide administration improved therapeutic effects in melanoma tumours. We observed both significant inhibition of tumour growth and extended survival of treated mice. To our knowledge, this is one of the first reports showing antitumour efficacy of electroporation-mediated vasostatin gene therapy combined with antiangiogenic chemotherapy.

Published: November 2019

Bleeding complication and abnormal platelet functions are associated with liver cirrhosis. The aim of the present investigation was to assess the functional integrity of platelets in terms of lipids like cholesterol and phospholipids, glycoproteins and membrane-bound enzymes. Liver cirrhotic patients with bleeding complications were studied. Age and sex matched normal healthy volunteers were also involved in this study as a control group. Levels of cholesterol, phospholipids, glycoproteins and adenosine triphosphatases were assessed in isolated platelet membrane fraction. The level of glycoproteins and the activity of adenosine triphosphatases were found to be decreased significantly in cirrhotic patients. The cholesterol/phospholipid ratio was found to be altered significantly, indicating an alteration in the fluidity of platelet membrane. The results of this study reveal that the functional impairment of platelets in liver cirrhotic patients which is responsible for their bleeding tendency might also be due to altered lipid and enzyme levels in platelet membrane.
Conformational properties of N-acetyl-N-methyl-alpha,beta-dehydroalanine N'-methylamide.
Authors: Macedowska Agnieszka , Siodłak Dawid , Rzeszotarska Barbara
Published: November 2019

The conformational properties of Ac-Delta(Me)Ala-NHMe (N-acetyl-N-methyl-alpha,beta-dehydroalanine N'-methylamide), as the simplest model of N-methyl-alpha,beta-dehydroamino acids, was examined with theoretical methods and in comparison with Ac-DeltaAla-NHMe and Ac-DeltaAla-NMe(2). The N-terminal amide of the Delta(Me)Ala residue easily adopts the configuration cis and the torsion angles phi, psi are highly flexible. The Delta(Me)Ala residue is a conformational flexibilizer as compared to the parent DeltaAla, which is a conformational stiffener. This seems to be the reason why Delta(Me)Ala is found in small natural cyclic peptides, where it ensures the conformational flexibility necessary for biological action.
Competence-based approach to a module design for the Master Degree Programme in Translation: Challenge of Tuning Russia Tempus Project
Authors: Zabotkina Vera , Korovkina Marina , Sudakova Olga
Published: November 2019

The article demonstrates the application of the modular competence-based approach for the design of a Master degree programme in translation studies. The case study is based on output materials produced during the lifetime of the Tuning Russia project involving a number of Russian universities, one of which is the Russian State University for the Humanities (RSUH). The module in question – the LSP (language for special purposes) translation module – emphasizes interaction between the related disciplines on the basis of the common subject-matter, i.e. the translation of special purpose texts. The modular approach sets out to achieve key competences required for professional qualifications. In addition, the module considers teaching methods, ECTS and assessment tools. Attention is given to the concept of competence-based approach in contemporary education. The authors argue that the competence-based approach introduced in Russia at the national (Ministerial) level in 2016 facilitates Russia’s interactive alignment with the main principles of the Bologna Process adopted by the European Higher Education Area.Received: 01 April 2019Accepted: 24 June 2019Published online: 29 November 2019

O objetivo desta pesquisa é verificar a associação entre o nível de evidenciação dos ativos intangíveis e o desempenho econômico financeiro dos clubes de futebol brasileiros. A amostra da pesquisa são os clubes que participaram do Campeonato Brasileiro das Séries A e B de 2017, visto que foram analisados os anos de 2013 a 2016. Para medir o nível de evidenciação, utilizou-se a norma em vigência ITG 2003 R1, e para medir o desempenho econômico-financeiro foram utilizadas seis variáveis: receita líquida, resultado líquido do exercício, patrimônio líquido, ativo intangível, ativo total e intangibilidade. Adicionalmente, também se analisou a variável auditoria. Com relação aos resultados da pesquisa, apenas o resultado líquido e o ativo intangível estão associados ao nível de evidenciação. Concluiu-se também que os clubes são parcialmente transparentes, em razão de metade da amostra apresentar um nível de evidenciação acima da média (cerca de 60%), o que sugere que entre os clubes analisados é preciso ser mais abrangente na evidenciação das informações para se adaptar completamente à norma de contabilidade.

Актуальность исследования обусловлена целесообразностью использования модельных представлений, адекватных реальным физико-геологическим условиям, при редуцировании результатов магниторазведки в областях развития платобазальтов. Цель: оценка влияния сферичности Земли на аномальное магнитное поле в условиях резко расчлененного рельефа дневной поверхности, сложенного магматическими горными породами, обладающими повышенной намагниченностью (на практических материалах). Методы: вычисление поправок за влияние магнитного рельефа местности путем решения прямой задачи магниторазведки для области с радиусом 20 км в двух вариантах: для плоской и шарообразной моделей Земли. Выполнено сопоставление полученных результатов и пространственно-статистический анализ выявленных различий. Предполагалось, что вектор намагничивания слагающих рельеф горных пород направлен по современному геомагнитному полю региона. Переменная по латерали эффективная намагниченность верхней части разреза определялась путем решения линейной обратной задачи магниторазведки. Результаты. Кратко охарактеризована проблема учета влияния рельефа местности при измерениях магнитного поля над вулканогенными образованиями. На примере материалов крупномасштабной высокоточной аэромагнитной съемки, выполненной в центральной части Норильского рудного района, показаны нелинейные искажения сигнала, связанные с криволинейностью земной поверхности. Амплитуда этих искажений (по модулю) достигает 100–200 нТл и более при сравнительно небольших различиях высотных отметок для разных моделей. Это объясняется высокими значениями вертикального градиента магнитного поля. Выводы. С целью подавления интенсивных аномалий-помех, обусловленных магнитными породами, слагающими верхнюю часть геологического разреза, предложено вычисление топографических поправок с использованием сферической модели Земли. Представляется также перспективным использование статистического подхода, в неявном виде учитывающего форму земной поверхности, для выделения аномалий «рельефной» природы.

Published: November 2019

Актуальность исследования состоит в том, что решением преждевременного прорыва воды или газа в горизонтальной скважине из-за неоднородности профилей притока вдоль оси горизонтального ствола, является изменение пластового давления на различных участках, а также при разработке контактных месторождений, особенно по мере истощения залежи, могут служить устройства контроля притока флюида. Различают активные Interval Control Valve (ICV) или пассивные Inflow Control Device (ICD) устройства. Устройства ICD способны выровнять приток вдоль горизонтальной скважины за счет создания дополнительного сопротивления потоку жидкости, зависящего от величины притока на данном горизонтальном участке. Недостаток современных ICD в том, что они не имеют возможности регулирования и приведения пассивных устройств в действие после установки в стволе скважины. В связи с тем, что имеются риски связанные с неопределенностью в описании свойств пласта, которые присутствуют на всех стадиях разработки месторождения недостаток ICD оказывается существенным. Системы ICV приводятся в действие дистанционно с поверхности скважины, но не способны определять характер поступающего флюида (нефть, газ, вода) в скважину и принимать решение в автоматическом режиме. Цель: разработка новой конструктивной схемы устройства контроля притоком с возможностью непрерывного мониторинга характера поступающей жидкости, и программного обеспечения для управления клапаном с устья скважины. Объекты: горизонтальная скважина и устройство контроля притоком флюида. Методы: имитационное моделирование Simulink, нейронные сети, матричные методы, методы линеаризации нелинейных уравнений.

FROM INCULCATING ISLAMIC VALUES TO ‘RAHMATAN-LIL-ALAMIN’: PROMULGATING VARIOUS APPROACHES OF ISLAM IN MALAYSIA
Authors: Zamri bin Ahmad Abdul Mua’ti
Published: November 2019

The government of Malaysia has introduced ‘Inculcating Islamic Values’ during the reign of Prime Minister Dr Mahathir in the 80s, ‘Civilizational Islam (Islam Hadhari)’ during the reign of Prime Minister Abdullah Badawi in 2004, ‘Wasatiyah’ during the reign of Prime Minister Najib Razak in 2010 and ‘Rahmatan-lil-Alamin’ recently in 2018 under the new government. All the approaches were designed towards developing a modern society in predominantly Malay-Muslim society of Malaysia. The concepts were normally publicized as a part of the manifesto during the political campaigns prior to the general elections. Since then, Malaysians, Muslims and non-Muslims alike were expecting to observe more detail explanations of the concepts and how it could be translated into actions in the multi-religion society. Occasionally the Prime Minister will reiterate the approaches and spell out in detail the methods of implementing the concept or to translate the concepts into policies. The concepts will further be elaborated in a couple more speeches delivered by the Prime Minister and senior ministers including the information minister. The mainstream media has also allotted special columns and programs to outspread the concepts even though at times not in detail and lack of continuity. Today, after about one year since the latest concept (Rahmatan-lil-alamin) has been conceived, what are the peoples’ perceptions towards it? Do the people really made to understand the concept?

Resumen: Este trabajo trata de mos­trar un retrato de los profesores más impor­tantes de la Universidad de Valencia en los años de Felipe II y primeros años del reinado de Felipe III. Se describen las distintas trayec­torias vitales de profesores de los estudios de latinidad y de las distintas facultades. La sucesión de maestros y discípulos es la cons­tatación de que en los años finales del siglo XVI y primeros del siglo XVII asistimos en Valencia al paso de la Universidad del huma­nismo a la universidad de la contrarreforma provocado por el relevo en los profesores, la aplicación de los decretos de Trento al ámbito de la cultura, la aparición de las cátedras pa­vordías y la crisis económica que afecta a la ya maltrecha economía de la Universidad.Palabras clave: Universidad Valencia, profesores, humanismo, reforma católica.Abstract: This research intends to show a biographical portrait of the most im­portant professors of the university of Valen­cia during the reign of Philip II and the first years of the reign of Philip III. It focuses on the different vital trajectories of the profes­sors of the studies of Latinity and the various faculties. The succession of professors and disciples is the confirmation that, in the final years of the 16th century and the beginning of the 17th century, Valencia is witnessing the turn of the Humanism university into the Counter-Reformation university. This was mainly caused by the replacement of profes­sors, the application of the decrees of Trent to the field of culture, the emergence of the pavordía chairs and the economic crisis that affected the already battered economy of the university.Keywords: University of Valencia, tea­chers, humanism, catholic reform.

ANALISIS KETIMPANGAN PEMBANGUNAN EKONOMI DAN KETIMPANGAN DISTRIBUSI PENDAPATAN DI PROVINSI KALIMANTAN SELATAN (STUDI KASUS KOTA BANJARMASIN DAN KABUPATEN TANAH BUMBU)
Authors: Suntari Martin Vegarika , Yunani Ahmad
Published: November 2019

Penelitian ini bertujuan untuk mengetahui bagaimana tingkat ketimpangan pembangunan ekonomi dan ketimpangan distribusi pendapatan di Kota Banjarmasin dan Kabupaten Tanah Bumbu serta bagaimana komparatif dari ketimpangan pembangunan ekonomi dan ketimpangan distribusi pendapatan pada dua wilayah tersebut. Penelitian ini  menggunakan data sekunder runtun waktu tahun 2013-2017 yang diperoleh dari BPS. Analisis tingkat ketimpangan pembangunan ekonomi dengan menggunakan indeks Williamson, sedangkan untuk menganalisis ketimpangan distribusi pendapatan dengan menggunakan indeks gini rasio.
                Hasil analisis komparatif indeks Williamson dan indeks gini rasio selama tahun 2013-2017 didapatkan bahwa masing-masing alat analisis memiliki hasil yang berbeda sehingga dapat dijabarkan saat tingkat ketimpangan pembangunan ekonomi wilayah tinggi untuk wilayah Kabupaten Tanah Bumbu dengan rata-rata 0,171 terjadi karena peran sektor ekonomi yang bertumpu pada SDA (pertambangan dan penggalian), kurang lancarnya mobilitas barang dan jasa(penyebaran barang dan migrasi). Akan tetapi tingkat ketimpangan distribusi pendapatannya rendah dengan rata-rata sebesar 0,312 karena deprensiasi pekerjaan masyarakatnta yang tidak jauh berbeda sehingga distribusi pendapatannya lebih merata. Saat ketimpangan pembangunan ekonomi Kota Banjarmasin rendah dengan rata-rata 0,021 terjadi karena Kota Banjarmasin merupakan pusat/konsentrasi perekonomian di Provinsi Kalimantan Selatan (ibukota provinsi) selain juga memiliki kesediaan infrastruktur yang lebih lengkap dari wilayah lain, akan tetapi tingkat ketimpangan distribusi pendapatannya tinggi dengan rata-rata 0,354 terjadi karena perbedaan jenis pekerjaan dan skill yang dimiliki masyarakat Kota Banjarmasin serta memiliki luas wilayah ynag kecil sehingga terjadi ketidakmerataan distribusi pendapatan.

Assessing OpenStreetMap Completeness for Management of Natural Disaster by Means of Remote Sensing: A Case Study of Three Small Island States
Authors: Goldblatt Ran , Jones Nicholas , Mannix Jenny
Published: November 2019

Over the last few decades, many countries, especially Caribbean island ones, have been challenged by the devastating consequences of natural disasters, which pose a significant threat to human health and safety. Timely information related to the distribution of vulnerable population and critical infrastructure are key for an effective disaster relief. OpenStreetMap (OSM) has repeatedly been shown to be highly suitable for disaster mapping and management. However, large portions of the world, including countries exposed to natural disasters, remain unmapped. In this study, we propose a methodology that relies on remotely sensed measurements (e.g. VIIRS, Sentinel-2 and Sentinel-1) and derived classification schemes (e.g. forest and built-up land cover) to predict the completeness of OSM building footprints in three small island states (Haiti, Dominica and St. Lucia). We find that the combinatorial effects of these predictors explain up to 94% of the variation of the completeness of OSM building footprints. Our study extends the existing literature by demonstrating how remotely sensed measurements could be leveraged to evaluate the completeness of OSM database, especially in countries at high risk of natural disasters. Identifying areas that lack coverage of OSM features could help prioritize mapping efforts, especially in areas vulnerable to natural hazards and where current data gaps pose an obstacle to timely and evidence-based disaster risk management actions.

This study was conducted in a laboratory-controlled environment aiming at studying the physical properties and elemental composition of coal combustion particles in a brazier. Particles were sampled ~1 m above the stove using a partector, where particles were collected on gold Transmission Electron Microscopy (TEM) grids and polycarbonate filters for TEM and inductively coupled plasma mass spectrometry (ICP-MS) analysis, respectively. Particles for elemental analysis collected on a 37 µm polycarbonate filters whereby a Gillian pump was used to draw in air. During sampling, a 2.5 µm cyclone was attached to the sampling cassette to isolate larger particles. The results have shown that combustion particles emitted during the early stage of combustion where single spherical particles with a diameter of around 450 nm. As the combustion progresses, the particle diameter gradually decreases and the morphology changes to accretion chain and fluffy bead structure for the flaming and char-burning phase, respectively.

Buah pepaya (Carica papaya L.) tergolong buah yang populer dan digemari oleh hampir seluruh masyarakat di dunia. Pepaya banyak dibudidayakan oleh masyarakat baik sebagai hobi ataupun usaha komersil. Hal ini karena pepaya memiliki banyak kelebihan. Buah pepaya menjadi salah satu komoditi yang sangat mudah rusak, hal tersebut terjadi akibat beberapa faktor, seperti: aktivitas dan pertumbuhan mikroba pada buah pepaya, aktivitas enzim-enzim di dalam buah pepaya, perlakuan suhu, serta beberapa faktor lainnya yang dapat merusak buah pepaya. Dehidrasi osmosis merupakan teknik pengurangan kadar air yang dapat digunakan untuk mengatasi permasalahan tersebut yaitu dengan cara perendaman bahan pada larutan berkonsentrasi tinggi. Penelitian ini dilaksanakan pada bulan September 2018 hingga bulan Oktober 2018 di Laboratorium Pengolahan Pangan dan Analisis Kimia Universitas Hasanuddin. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh suhu dan konsentrasi larutan gula terhadap kadar air akhir, penurunan bobot (WR), jumlah padatan yang masuk (SG) dan jumlah air yang keluar dari bahan (WL) pada pepaya selama proses dehidrasi osmosis dan mengetahui suhu dan konsentrasi yang optimal dalam proses dehidrasi pepaya. Metode yang digunakan pada penelitian ini adalah dengan menggunakan rancangan acak lengkap yang disusun secara faktorial dengan 2 faktor dan masing-masing faktor terdiri atas 3 level yaitu kadar gula 40 Brix, 50 Brix, 60 Brix dan suhu perendaman 40 C, 50 C, 60 C dengan 3 kali ulangan. Berdasarkan hasil penelitian diperoleh bahwa perlakuan suhu 60  dan konsentrasi larutan 60 Brix menghasilkan kadar air yang paling rendah, dan sama halnya seperti peningkatan nilai Solid Gain (SG) paling tinggi juga terjadi pada suhu 60 C dan konsentrasi 60 Brix. Perlakuan suhu perendaman 50 C dan konsentrasi larutan gula 50 Brix menghasilkan Weight Reduction (WR) yang paling tinggi, sedangkan nilai Water Loss (WL) yang paling tinggi juga berada pada kombinasi perlakuan suhu perendaman 50 C dan konsentrasi larutan gula 50 Brix.
