Virtual vertical plasma drifts estimated from hourly virtual heights (h’F2) extracted from the digisonde found on GIRO’s website are used in this recent study by engaging the international quiet days (IQDs) conditions. Virtual vertical plasma drifts () estimated from low latitude F2-region virtual heights was examined over Ilorin (lat. 8.31°N, long. 4.34°E, dip lat. 2.95o) during solar minimum (SM), a station Located along the latitudinal hollow. The 10-international quiet days (IQDs) monthly averages across each hourly period of the day were used for the estimation. Two characteristics of highlighted are the pre-noon and the post-noon peaks of the diurnal patterns for each season. The pre-noon peaks magnitudes between 0800 LT and 0900 LT are 6.8, 14.4 and 15.0 m/s for June Solstice, Equinox and December Solstice respectively; and its post-noon peaks magnitudes around 1800 LT evening time are 0.8, 7.4 and 7.9 m/s foe December and June Solstices, and Equinox respectively. displayed an enhanced phenomenon of slight-transitory spikes having magnitudes of -0.3 m/s (December Solstice) and -0.8 m/s (Equinox), and 3.6 m/s (June Solstice) around 1200 LT noontime. Finally, depicted pre-reversal enhancement (PRE) night peaks for the entire season. The PRE peaks magnitudes are [(-4.0)–(-13.4)] m/s at 2000 LT, [(-4.9)–(-9.3)] m/s between 2200 LT and 2300 LT, [(-3.6)–(-6.6)] m/s between 0100 LT and 0200 LT and [(-3.0)–(-6.4)] m/s between 0300 LT and 0400 LT respectively for all seasons. Same phenomenon in the annual pattern as showcased in the diurnal patterns occurred. In general, magnitudes were highest in Solstices and lowest in Equinox during solar minimum. The gradually and continuous decay is ensued by the electrons hastily turnoff movement from the low latitude due to solar ionization for all seasons
Da ruína como discurso: Apontamentos sobre cinematografias pós-coloniais
Authors: MIRIAN TAVARES  
Published: July 2024

RESUMO: O cinema foi inventado na tarda-modernidade, engendrando um discurso, um aparelho, uma arquitetura e uma proposição. Para perceber o seu alcance, não pode ser retirado do contexto em que nasceu e nem se podem ignorar as implicações espácio-temporais que o visionamento dos filmes provocou nos seus contemporâneos. De que maneira, então, os realizadores dos países africanos de língua portuguesa constroem um discurso próprio, dentro de um dispositivo herdado do período colonial? Como colabora o cinema no processo de construção identitária? De que maneira alguns cineastas habitam as ruínas do colonialismo? E como eles subvertem o conceito tradicional de ruínas, que se transforma num modelo de resistência ao novo, ao estrangeiro? Através da análise de alguns filmes de realizadores de Moçambique, Cabo Verde e Guiné-Bissau, procuro perceber as semelhanças e dissemelhanças do uso do dispositivo cinematográfico na construção de discursos audiovisuais no período pós-colonial.
PALAVRAS-CHAVE: cinema africano, ruínas, identidade, representação
ABSTRACT: Having been invented in the late modernity, cinema has engendered its own discourse, apparatus, architecture, and propositions. To acknowledge a film’s full scope, one must not neglect the context in which it was created; nor can one ignore the spacetime implications it has had for its contemporary spectators. In what manner have directors from African Portuguese-speaking countries constructed their own discourse within a device inherited from the colonial period? And how have they subverted the traditional concept of ruin, which has become a model of resistance to what is new, to what is foreign? How do some directors inhabit the ruins of colonialism? Through the analysis of some films from countries such as Mozambique, Cape Verde, and Guinea Bissau, I attempt to understand the similarities and dissimilarities in the use of cinematographic devices in the construction of audiovisual discourses in the postcolonial period.

Saramago for Beginners: Reflections on Teaching “Coisas” as an Introduction to Saramaguian Dystopia, Allegory, and Political Critique
Authors: HAYSOM-RODRIGUEZ PETER 
Published: July 2024

ABSTRACT: This essay offers a rationale and methodology for introducing students to the fiction of José Saramago through a lesser-known text: his short story “Coisas,” from the collection Objecto quase (1978), which was taught to first-year undergraduate students at the University of Nottingham in 2019 and 2020. The article begins by justifying the inclusion of Saramago’s work—and, specifically, the short story in question—on an undergraduate Lusophone studies syllabus. It is argued that “Coisas” concisely encapsulates Saramago’s key literary themes in approachable and easily digestible prose, while containing both contextually specific and universally relevant allusions within a form and genre likely to appeal to young adults. Second, the essay outlines and critically reflects upon the lesson plans and pedagogical strategies used to teach this narrative in previous years, before and during the COVID-19 pandemic. Finally, the article suggests some further methods for teaching “Coisas” to Lusophone studies undergraduates and contemplates other pedagogical contexts in which Saramago’s short story might be deployed successfully in the future.
KEYWORDS: José Saramago; short story; pedagogy; dystopia; allegory
RESUMO: Este ensaio propõe uma justificação e uma metodologia pedagógica relativamente ao ensino introdutório à obra ficcional de José Saramago, através de um texto pouco conhecido: o conto “Coisas,” da colectânea Objecto quase (1978), que foi analisado com estudantes de primeiro ano na Universidade de Nottingham (2019–20). Em primeiro lugar, o artigo problematiza a inclusão da obra de Saramago no programa de uma disciplina de Estudos Lusófonos, com especial ênfase no conto em questão. Defende-se que “Coisas” resume, de forma relevante, algumas das principais questões da obra de Saramago através de uma prosa accessível, e que esta narrativa distópica e alegórica alude tanto a contextos específicos como a circunstâncias universais, utilizando um género literário capaz de instigar jovens adultos. Em segundo lugar, o artigo propõe uma reflexão crítica sobre as estratégias e planos pedagógicos utilizados para ensinar este conto durante a pandemia de COVID-19, e antes dela. Em último lugar, apresentam-se modelos alternativos para ensinar “Coisas” em aulas do ensino universitário na área de Estudos Lusófonos, assim como noutros contextos pedagógicos nos quais se poderia ensinar esta narrativa saramaguiana no futuro.

MASALAH SOSIAL PADA PERTAMBANGAN ILEGAL DAN IMPLEMENTASI KEBIJAKAN N0 88/DLH 2021 KABUPATEN BUNGO
Authors: Mutholib Abdul 
Published: July 2024

Penambangan ilegal terus mengalami perkembangan, dalam keberlangsunganya, aktivitas ini tidak mengantongi izin, dan tidak menerapkan prinsip-prinsip pertambangan yang baik dan benar (good mining practice). Terjadi kemudian aktivitas ini memimbulkan masalah-masalah sosial di Tengah Masyarakat. Penelitian ini bertujuan untuk melihat bagaimana implementasi kebijakan Peraturan Daerah No 88/DLH 2021 dalam menertib dan mengawasi aktivitas pertambangan tanpa izin di Kabupaten Bungo, serta menggali lebih dalam apa saja yang menjadi penghambat dalam proses pelaksaan PERDA tersebut. Jenis penelitian ini kualitatif-deskriktif-analisis dengan menggambarkan fenomena dan realitas lapangan dengan apa adanya. Informan dalam penelitian ini adalah Tim Tepadu Penanganan Tambang Ilegal yaitu, Dinas Lingkungan Hidup, Kadis SDA, Kesbangpol dan Camat. Berdasarkan temuan lapangan, adapaun langkah strategis pencegahan yaitu 1) membentuk Tim Terpadu penanganan PETI, 2) mengeluarkan surat edaran PETI, 3) melakukan sosialisasi ke desa dan kecamatan, 4) bekerja sama dengan media dan Lembaga Swadaya Masyarakat pemerhati lingkunn dan, 5) mendayagunakan peran Camat dan Datuk Rio (Kepala Desa). Langkah-langkah penindakan aktivitas PETI adalah 1) melakukan razia gabungan ke lokasi PETI, 2) mendorong tokoh adat dalam memberikan sanksi bagi pelaku PETI, 3) menjadi saksi dalam proses hukum bagi pelaku PETI, serta 4) melakukan uji sampel air yang tercemar. Faktanya tidak semua kebijakan dapat terlaksana dengan baik karena antara lain : 1) kurangnya pola pikir positif masyarakat terhadap lingkungan, 2) adanya penolakan saat operasi terpadu, 3) sulitnya pendataan kasus PETI, dan 4) adanya keterlibatan oknum yang tidak bertanggungjawab.
Suppression of severe achondroplasia with developmental delay and acanthosis nigricans by the p.Thr651Pro mutation

Published: October 2013

AbstractSevere achondroplasia with developmental delay and acanthosis nigricans (SADDAN) is an extremely rare severe skeletal dysplasia characterized by significant developmental delay, brain structural abnormalities, hearing loss, and acanthosis nigricans. The disorder is the result of a single missense mutation at codon 650 (p.Lys650Met) in the fibroblast growth factor receptor 3 gene (FGFR3). We describe a child who initially presented with a mild achondroplasia or hypochondroplasia like phenotype. Molecular analysis of the FGFR3 gene showed the common SADDAN mutation and a second novel mutation at codon 651 (p.Thr651Pro). Both mutations were shown to occur on the same allele (cis) and de novo. Transient transfection studies with FGFR3 double mutant constructs show that the p.Thr651Pro mutation causes a dramatic decrease in constitutive receptor kinase activity than that observed by the p.Lys650Met mutation. Our data suggest that the molecular effect by the p.Thr651Pro is to elicit a conformational change that decreases the FGFR3 tyrosine kinase activity, which is constitutively activated by the SADDAN mutation. Due to the inheritance of both a gain‐of‐function and a loss‐of‐function mutation, we conclude that a reduction of constitutive activation caused the milder skeletal phenotype. Although the occurrence of double mutations are expected to be rare, the presence of other FGFR3 modifiers may be responsible for some of the clinically discrepant skeletal dysplasia cases. © 2013 Wiley Periodicals, Inc.
Chitosan‐sodium lauryl ether sulfate particles and their use for adsorption of Cu(II) ions

Published: October 2013

AbstractThe synthesis of small particles through the interaction between chitosan (CS) and sodium lauryl ether sulfate (SLES) was studied. Depending on working condition, microparticles at atmospheric pressure and ultrafine particles at high pressure have been obtained. At atmospheric pressure, the microparticles were formed instantaneously when the CS solution was dripped into the SLES aqueous solution. To obtain ultrafine particles, the surfactant solution in contact with high pressure carbon dioxide was sprayed into chitosan solution. Fourier Transform Infrared Spectroscopy proves the interaction between the sulfate groups of SLES and the amino groups of CS. The Scanning Electron Microscopy reveals that the microparticles are quasi‐spherical, but some of them can take the form of pellets depending on preparation conditions. The obtained microparticles were successfully used to uptake Cu(II) ions from aqueous solutions. The adsorption of Cu(II) depends on pH being maximum at pH = 5.5. The kinetic experiments demonstrated that Cu(II) adsorption onto CS/SLES microparticles obeys the Langmuir model. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40059.
Birch encroachment affects the base cation chemistry in a restored bog
Authors: Wertebach Tim‐Martin , Hölzel Norbert , Kleinebecker Till 
Published: October 2013

ABSTRACTIn this study, we compared non‐forested and forested habitat types of a degraded bog in Western Germany with regard to the base cation chemistry of their pore waters. Peat profiles were sampled in 10‐cm intervals every month from April to July 2009 down to a maximal depth of 150 cm. Pore waters were analysed for Ca, Mg, K and Na concentrations. Additionally, electrical conductivity and pH were measured in surface pools. Both habitat types were sampled with four replicate plots, showing the same vegetation structure.Strong differences were found between the concentrations and distributions of base cations in the pore water profiles from the different habitat types. The forested sites revealed higher concentrations for all base cations, but especially for Ca and Mg. Seasonality had an effect on element distributions in pore waters, but its influence was particularly strong at the forested sites. Element distributions and seasonality were caused by several interacting biological and physicochemical processes, such as plant uptake and mineralization or evaporative enrichment and dilution by rainwater. Concludingly, we draw implications for bog restoration and for the use of element ratios as criterion of mineral influence on bog waters. Our study clearly demonstrates the enhancement of base cation supply by birch encroachment, which is posing an additional burden on successful bog restoration. Additionally, the importance of an intact buffer zone around restored peat bogs is underlined. Copyright © 2013 John Wiley & Sons, Ltd.
P‐Terthienyl‐Functionalized Dithieno[3,2‐b:2′,3′‐d]phospholes
Authors: Chua Chris Jansen , Ren Yi , Stolar Monika , Xing Shirley , Linder Thomas , Baumgartner Thomas 
Published: October 2013

AbstractA series of dithienophospholes with different P‐thienyl substituents have been synthesized and characterized. Alkyl groups at the 2,6‐positions of the scaffold were introduced for solubility, but were found to also prevent π stacking with this scaffold. Whereas a simple thienyl does not affect the overall photophysics of the dithienophosphole, the installation of terthienyl units creates a considerable subchromophore that can communicate through the phosphole‐typical σ*–π* orbital interaction with the main scaffold. The overall architecture of the terthienyl was also found to have a significant impact on the photophysics of the system. Although a heavily twisted, branched terthienyl does not allow for any intermolecular π‐stacking interaction, the exposed nature of a linear terthiophene does, and gives rise to the formation of excimers in solution, as evident in shifted emission properties as a function of the concentration. Time‐dependent DFT calculations have revealed that in this case, the terthienyl group becomes the main chromophore and the dithienophosphole only plays a supportive role.

Published: October 2013

AbstractBackgroundPharyngocele or a lateral pharyngeal diverticulum (LPD) are rare lesions, which are bulgings of the pharyngeal mucosal surface through one of the weak areas of the pharynx.MethodsThe external approach has been the primary surgical treatment of pharyngoceles. The purpose of this article was for us to report an endoscopic successful treatment of pharyngocele by suture pharyngoplasty.ResultsEndoscopic suture pharyngoplasty does not require an external incision and hospitalization. After 3 months of abstinence from trumpet playing, the patient is back to his musical career.ConclusionBecause of the minimally invasive procedure, endoscopic suture pharyngoplasty can be performed in case of symptomatic pharyngoceles with a good result. © 2014 Wiley Periodicals, Inc.

Published: October 2013

PurposeTo test the hypothesis that magnitude images from cine displacement encoding with stimulated echoes (DENSE) magnetic resonance imaging (MRI) can accurately quantify left ventricular (LV) volumes, mass, and ejection fraction (EF).Materials and MethodsThirteen mice (C57BL/6J) were imaged using a 7T ClinScan MRI. A short‐axis stack of cine T2‐weighted black blood (BB) images was acquired for calculation of LV volumes, mass, and EF using the gold standard sum‐of‐slices methodology. DENSE images were acquired during the same imaging session in three short‐axis (basal, mid, apical) and two long‐axis orientations. A custom surface fitting algorithm was applied to epicardial and endocardial borders from the DENSE magnitude images to calculate volumes, mass, and EF. Agreement between the DENSE‐derived measures and BB‐derived measures was assessed via coefficient of variation (CoV).Results3D surface reconstruction was completed on the order of seconds from segmented images, and required fewer slices to be segmented. Volumes, mass, and EF from DENSE‐derived surfaces matched well with BB data (CoVs ≤11%).ConclusionLV mass, volumes, and EF in mice can be quantified through sparse (five slices) sampling with DENSE. This consolidation significantly reduces the time required to assess both mass/volume‐based measures of cardiac function and advanced cardiac mechanics. J. Magn. Reson.

Published: October 2013

PurposeTo evaluate the distribution and extent of myocardial fibrosis identified by either contrast‐enhanced Look–Locker or late gadolinium enhancement magnetic resonance imaging (LGE MRI) and their relationships between ventricular tachyarrhythmia or risk factors in apical hypertrophic cardiomyopathy (APH).Materials and MethodsTwenty‐five APH patients were examined using a 3.0 T or 1.5 T instrument. We used MRI to evaluate myocardial T1 values and scar. We compared the myocardial fibrosis assessed by contrast‐enhanced Look–Locker or LGE MRI with ventricular tachyarrhythmia or risk factors for hypertrophic cardiomyopathy.ResultsMyocardial scar was present in 17 of the 25 patients with APH. Myocardial scar was distributed predominantly in the apical myocardium (P < 0.01), whereas myocardial T1 values did not differ between the apical, midventricular, and basal septum. The extent of myocardial scar according to 16‐segment model and ejection fraction were related to ventricular tachyarrhythmia or risk factors in APH (P < 0.05 for both). The myocardial T1 value was not associated with the tachyarrhythmia or risk factors.ConclusionIn APH, the extent of myocardial scar on LGE MRI is associated with ventricular tachyarrhythmia and risk factors. Quantification of the myocardial T1 value is not necessary for its risk stratification. J. Magn. Reson. Imaging 2014;40:407–412 © 2013 Wiley Periodicals, Inc.
The sequencing of “related” jobs
Authors: Elmaghraby Salah E. 
Published: October 2013

AbstractGiven n jobs and a single facility, and the fact that a subset of jobs are “related” to each other in such a manner that regardless of which job is completed first, its utility is hampered until all other jobs in the same subset are also completed, it is desired to determine the sequence which minimizes the cost of tardiness. The special case of pairwise relationship among all jobs is easily solved. An algorithm for the general case is given through a dynamic programming formulation.
Simulations to explore alternative sequencing rules
Authors: Brown Robert G. 
Published: October 2013

AbstractA flexible simulation system has been designed to permit investigation of sequencing rules in a large job shop, with continual input of new work. The objective is to understand what happens rather than to find optimum rules, with many conflicting measures of effectiveness: work in process, finished goods investment, delays, machine and labor utilization, and effort to implement. A few problem areas have been explored.
Optimal spares for stochastically failing equipment
Authors: Falkner Charles H. 
Published: October 2013

AbstractA mathematical model is formulated for determining the number of spare components to purchase when components stochastically fail according to a known life distribution function and there is a cost incurred when a component is replaced. Bounds are determined for the optimal inventory which indicate that the inclusion of the replacement cost lowers the optimal inventory.Since these bounds are no easier to calculate than the optimal spares level, the theory is specialized to components with exponentially distributed time to failure. Procedures are given for calculating the optimal spares level, and numerical examples are provided.
