Full textAbstract:
Heterophrynus batesii (the Giant Amazonian Whip Spider) are often referred to as “whip scorpions” or “whip spiders” because of their very long antenniform legs (i.e., whips), but they are neither scorpions nor spiders. They are amblypygids, a type of harmless charismatic arachnid with an alien-like appearance that students are drawn to. I have developed care and breeding techniques that are effective at getting H. batesii to live and reproduce in captivity. I developed these techniques with other science teachers in mind. These techniques are simple, time efficient, utilize the least expensive materials, and require minimal space—important characteristics since most high school biology teachers are limited by time, money, and space. This article instructs high school biology students (under the guidance of their teacher) how to properly care for and develop a captive breeding program for H. batesii in their high school biology classroom. Topics, resources, and activities are also suggested that allow teachers to make educational connections between the H. batesii captive breeding program, the ongoing sixth mass extinction, and the destruction of the Amazon rainforest.

In use, the Z80 Trainer uses a keypad to write source code manually and then stored in volatile memory. The problem that often occurs is that the power supply to the Z80 Trainer is cut off so that the written program is not saved and has to be rewritten. This research is designed to build and control a backup power supply for SRAM on the Z80 Trainer using a battery, which can meet the power supply cut off from the PLN mains voltage to ensure that data and programs that have been written and stored in memory are not deleted. The method used in this research is the experimental method and the design of the tools carried out in the laboratory. This research has produced a tool that can control the backup power supply coming from the battery via a circuit of the switching control unit for the SRAM on the Z80 Trainer. The test results prove that the tool that has been made can control or build power in SRAM when the main power supply is cut off for less than 26 days using a Li-Ion battery type 18650 with a capacity of 3000 mAh. Testing the length of time to use the tool under normal conditions using a backup power supply to get the result of about ± 20 hours.

Full textAbstract:
Vibration energy harvesting has been progressively developed in the advancement of technology and widely used by a lot of researchers around the world. There is a very high demand for energy scavenging around the world due to it being cheaper in price, possibly miniaturized within a system, long lasting, and environmentally friendly. The conventional battery is hazardous to the environment and has a shorter operating lifespan. Therefore, ambient vibration energy serves as an alternative that can replace the battery because it can be integrated and compatible to micro-electromechanical systems. This paper presents the design and analysis of a MEMS piezoelectric energy harvester, which is a vibration energy harvesting type. The energy harvester was formed using Lead Zicronate Titanate (PZT-5A) as the piezoelectric thin film, silicon as the substrate layer and structural steel as the electrode layer. The resonance frequency will provide the maximum output power, maximum output voltage and maximum displacement of vibration. The operating mode also plays an important role to generate larger output voltage with less displacement of cantilever. Some designs also have been studied by varying height and length of piezoelectric materials. Hence, this project will demonstrate the simulation of a MEMS piezoelectric device for a low power electronic performance. Simulation results show PZT-5A piezoelectric energy with a length of 31 mm and height of 0.16 mm generates maximum output voltage of 7.435 V and maximum output power of 2.30 mW at the resonance frequency of 40 Hz.
ABSTRAK: Penuaian tenaga getaran telah berkembang secara pesat dalam kemajuan teknologi dan telah digunakan secara meluas oleh ramai penyelidik di seluruh dunia. Terdapat permintaan yang sangat tinggi di seluruh dunia terhadap penuaian tenaga kerana harganya yang lebih murah, bersaiz kecil dalam satu sistem, tahan lama dan mesra alam. Manakala, bateri konvensional adalah berbahaya bagi alam sekitar dan mempunyai jangka hayat yang lebih pendek. Oleh itu, getaran tenaga dari persekitaran lebih sesuai sebagai alternatif kepada bateri kerana ia mudah diintegrasikan dan serasi dengan sistem mikroelektromekanikal. Kertas kerja ini membentangkan reka bentuk dan analisis tenaga piezoelektrik MEMS iaitu salah satu jenis penuaian tenaga getaran. Penuai tenaga ini dibentuk menggunakan Lead Zicronate Titanate (PZT-5A) sebagai lapisan filem tipis piezoelektrik, silikon sebagai lapisan substrat dan keluli struktur sebagai lapisan elektrod. Frekuensi resonans akan memberikan hasil tenaga maksima, voltan tenaga maksima dan getaran jarak maksima. Mod pengendalian juga memainkan peranan penting bagi menghasilkan tenaga yang lebih besar. Reka bentuk yang mempunyai ketinggian dan panjang berlainan juga telah diuji dengan menggunakan bahan piezoelektrik yang sama. Oleh itu, projek ini akan menghasilkan simulasi piezoelektrik MEMS yang sesuai digunakan bagi alat elektronik berkuasa rendah. Hasil simulasi menunjukkan dengan panjang 31 mm dan ketinggian 0.16 mm, piezoelektrik PZT ini menghasilkan voltan maksima sebanyak 7.435 V dan tenaga output maksima 2.30 mW pada frekuensi resonans 40 Hz.

Full textAbstract:
We studied the chorionic morphology of six species of Hamadryas, and together with previous studies, we compared our results with previously published phylogenies for the genus. Samples were obtained from 19 females collected between 2013 and 2017 whose abdomens were sectioned and preserved for later dissection. Eggs were extracted from those dissections and used for the descriptions and illustrations of the chorion. The Hamadryas egg is of the globose type; it is quasi-spheroidal and has multiple polygonal grids with differentiation in specific zones/regions, and knolls with macrocells in their summits that arise in the apical third. These characteristics are very different from those found in the majority of Biblidinae and for those reported in the literature for Batesia and Panacea, which belong to the same subtribe as Hamadryas (Ageroniina, now Ageroniini). Chorionic characters support a previously suggested division of the genus (februa, feronia and laodamia groups) and they agree with the phylogenetic proposal based on morphological characters. Our study expands previous morphological work focused on this genus and compiles all the information available to date about the exochorion of Hamadryas, which now includes data for 10 species and that of Ectima thecla thecla, the putative sister group of Hamadryas.

Abstract. A community of ten ostracod species characterizes the hypersaline channels of Khor Al-Mufateh and Khor Al-Mamlaha. The dominant species in Khor Al-Mufateh are Loxoconcha (Loxoconcha) indica Jain, 1978; Gibboborchella venosa Gumey, 1979; Gibboborchella alata Gurney, 1979; and Hemicytheridea paiki Jain, 1978. L.(L.) indica, along with Neomonoceratina sp., dominate Khor Al-Mamlaha. Other species ranging from common to rare, include Carinocythereis (Carinocythereis) batei Jain, 1978; Callistocythere cf. flavidofusca intricatoides (Ruggieri), 1953; Loxoconcha (Loxoconcha) multiornata Bate & Gurney, 1981; Tanella cf. gracilis Kingma, 1948; and Xestoleberis rotunda Hartmann, 1964.Khor Al-Mufateh and Al-Mamlaha are divided into zones according to the distribution of ostracod species, which are dependant upon the richness and distribution of algae and the type of sediment. The ten ostracod species are salinity-tolerant and occur in the upper third of Khor Al-Mufateh and the lower half of Khor Al-Mamlaha with salinity ranging between 55–70‰ and 45–70‰, respectively. These zones are rich in algal growth with sediments varying from muddy carbonate sands to sandy mud. Most ostracod species are found in abundance during the summer exhibiting a rich diversity of algae genera and species.

Responden dalam penelitian ini adalah mahasiswa di berbagai perguruan tinggi negeri / swasta di Bali. Hasil dari penelitian ini adalah terdapat beberapa kendala yang dialami siswa dalam kegiatan belajar mengajar secara online yaitu penambahan biaya kuota internet yang meningkat hingga tiga kali lipat dari tarif biasanya, kemudian kendala sinyal internet mengakibatkan kegiatan belajar mengajar menjadi kurang efektif karena tersendat-sendatnya sinyal yang terkadang dapat memutus percakapan begitu saja, atau percakapan menjadi kurang jelas yang mengakibatkan salah komunikasi. Ada juga yang belum paham bagaimana cara menggunakan aplikasi tersebut, lalu kecanggihan atau type masing-masing hp atau laptop yang berbeda, yang menyebabkan perangkat elektronik tersebut terasa lebih berat pada memory atau ramnya. kemudian pada saat proses belajar mengajar berlangsung baterai lebih cepat habis, macet dan panas. Kemudian yang paling berbahaya adalah kesehatan mata yang bertahan lama di depan ponsel atau komputer atau laptop anda, akibat paparan radiasi yang tinggi dari layar atau LCD. Para orang tua juga mengeluhkan bahwa dengan belajar dari rumah, pengeluaran semakin meningkat, dan biaya UKT harus dibayar.

The analytical expression for the group index in a degenerated three-level lambda-type atomic system is derived as a function of the parameters of laser fields and external magnetic field. The influence of the external magnetic field on the group index is investigated. It is shown that by changing the magnitude or sign of the external magnetic field, the transparency window with normal dispersion switches to enhanced absorption with anomalous dispersion at the line center and hence the light propagation can be converted between subluminal and superluminal modes.

El objetivo principal de este estudio fue analizar las diferencias en la condición física, los hábitos de práctica de actividad física y el expediente académico de alumnos/as de 4º curso de Educación Secundaria Obligatoria en función del sexo y del tipo de actividad física practicada. En esta investigación participaron 156 alumnos/as (15.34 ± .58 años, 1.69 ± .09 cm, 58.97 ± 9.36 kg, 20.51 ± 2.10 kg/m2), 79 de sexo masculino (MASC) y 77 de sexo femenino (FEM). La condición física de los participantes se evaluó a partir de una batería de test físicos. La tipología de la AF fue analizada a través de las respuestas a distintos cuestionarios sobre los hábitos de práctica de actividad física en adolescentes (Enkid, Fitnessgram, Pace o el PAQ-A). El rendimiento académico (RA) se valoró mediante la media aritmética de las calificaciones del expediente académico de los alumnos/as desde su entrada al instituto. Los resultados obtenidos en nuestro estudio muestran que las chicas y los alumnos/as que practican actividad física extraescolar no competitiva (AF-NoCOMP) obtienen peores niveles (p < .05) de condición física en todas las cualidades excepto flexibilidad, pero mayores niveles de RA que los alumnos/as que practicaban AF competitiva (AF-COMP). Por el contrario, los chicos y los alumnos/as que practican AFCOMP tenían mejor condición física pero un menor RA. En conclusión, se observa de forma general que los chicos y los alumnos/as que realizan actividad física de carácter competitivo realizan una mayor frecuencia de AF por la tarde, obtienen mejores resultados en los test de condición física, pero sus niveles de RA son menores. Abstract. The aim of this study is to analyse the differences between physical fitness, the practise of physical activity (PA) and the academic performance (AP) of students of 4th grade of Secondary School. These differences are analysed as a function of gender and PA. 156 students took part in this study (15.34 ± .58 age, 1.69 ± .09 cm, 58.97 ± 9.36 kg, 20.51 ± 2.10 kg/m2), 56 male and 77 female. The participants’ physical fitness was evaluated by means of physical tests. PA was analyzed using different questionnaires (Enkid, Fitnessgram, Pace, or PAQ-A) assessing the teenagers’ physical activity habits. AP was evaluated using the arithmetic mean from the students’ high school academic records. The results of this study showed that girls and students who practise non-competitive PA have worse levels (p < .05) of physical fitness in every component analysed except flexibility, but their AP is higher. On the other hand, boys and students who practise competitive PA have better physical fitness and worse AP. To sum up, boys and students who participate in competitive PA show generally a higher frequency of PA practice during the afternoon. Furthermore, they obtain better results in physical fitness tests, even though their AP is worse.

AbstractA group of subarboreal tropical beetles, the Xystosomi of subtribe Xystosomina new subtribe, is revised and reclassified based on a reevaluation of structural characters. Xystosomi are found in tropical Australia (Queensland) and tropical/subtropical America (Guerrero, México, to Aguas Blancas, Argentina). The largest concentration of species occurs near the equator in the Amazon Basin, but a significant radiation of flightless forms was recently discovered in the northern Andes of Colombia, Ecuador, and Venezuela. Xystosomina also includes the Mioptachyi, which at present is composed of the genera Mioptachys and Inpa.Seventy-six species of Neotropical and Australian Xystosomi are described or re-described, illustrated, or keyed. This assemblage includes 12 classic species, 24 species described in the last 3 decades, and 40 new species, a 6-fold increase since the time of Henry Walter Bates, the last 19th-century entomologist to study this remarkable lineage of carabid beetles. The Xystosomi are now arrayed in five genera: Philipis gen.nov. (type: Tachys trunci Darlington, Australia), Geballusa gen.nov. (type: Xystosomus microtretus Erwin, Costa Rica), Gouleta gen.nov. (type: Bembidion cayennense Dejean, Brazil), Batesiana gen.nov. (type: Xystosomus gruti Bates, Brazil), and Xystosomus Schaum (type: Xystosomus inflatus Schaum, Brazil).The following specific taxa are described as new (type-locality in parentheses): Geballusa rex (Brazil: 06°02′N 050°17′W), oligotreta (Panamá: 08°40′N 079°56′W), nannotreta (Brazil: 02°54′S 059°57′W), Gouleta gentryi (Perú: 12°50′S 069°20′W), Batesiana para (Brazil: 01°22′S 048°20′W), angustia (Perú: 05°08′S 074°45′W), samiria (Perú: 05°08′S 074°45′W), esheje (Perú: 05°08′S 074°45′W), crassa (Perú: 03°15′S 072°55′W), notesheje (Perú: 03°15′S 072°55′W), manusculptilis (Perú: 12°07′S 070°58′W), parapara (Brazil: 02°28′S 046°26′W), am (Perú: 05°08′S 074°45′W), indetecticostis (Ecuador: 00°57′S 077°48′W), nox (Ecuador: 00°57′S 077°48′W), parkeri (Perú: 03°15′S 072°55′W), hamatilis (Ecuador: 01°02′S 077°40′W), notparkeri (Colombia: 00°08′N 075°51′W), pfunorum (Perú: 03°15′S 072°55′W), quadrata (Perú: 03°15′S 072°55′W), protosculptilis (Perú: 12°50′S 069°20′W), misahualli (Ecuador: 01°02′S 077°40′W), depressisculptilis (Ecuador: 01°02′S 077°40′W), irisculptilis (Ecuador: 00°24′S 076°37′W), foveosculptilis (Brazil: 02°28′S 046°26′W), punctisculptilis (Perú: 03°15′S 072°55′W), eugeneae (Perú: 11°56′47″S 071°17′00″W), anchicaya (Colombia: 03°43′N 076°57′W), jefe (Panamá: 09°12′N 079°21′W), exigupunctata (Perú: 05°08′S 074°45′W), rosebudae (Ecuador: 00°57′S 077°48′W), equanegrei (Ecuador: 00°57′S 077°48′W), henryi (Ecuador: 00°28′S 077°53′W), baeza (Ecuador: 00°57′S 077°48′W), huacamayas (Ecuador: 00°28′S 077°53′W), dannyi (Ecuador: 00°57′S 077°48′W), alticola (Colombia: 04°21′S 074°22′W), jacupiranga (Brazil: 24°42′S 048°00′W), chiriboga (Ecuador: 00°15′S 078°44′W), wygo (Colombia: 04°53′N 074°31′W).The following names are resurrected from synonymy for good species: hilaris Bates and belti Bates. Several name combinations were changed as a result of the generic reorganization: Philipis trunci (Darlington), Geballusa microtreta (Erwin), G. polytreta (Erwin), Gouleta notiophiloides (Erwin), G. spangleri (Erwin), G. cayennense (Dejean), Batesiana bisulcifrons (Erwin), B. negrei (Erwin), B. hilaris (Bates), B. belti (Bates), B. ampliata (Bates), B. strigosa (Bates), B. gruti (Bates), B. nigripalpis (Erwin), B. villiersi (Perrault), B. apicisulcata (Erwin), B. iris (Erwin), B. sculpticollis (Bates), B. sulcicostis (Bates), B. anterocostis (Erwin), B. ovatula (Bates), B. grossipunctata (Erwin), B. batesi (Erwin), B. seriata (Erwin), B. sublaevis (Bates), B. aetholia (Erwin), B. parainsularis (Erwin), NEW COMBINATIONS.Results of the Xystosomi character analysis provided impetus for a reanalysis of the classification of the major lineages of the more inclusive group, Bembidiini, to discover where the Xystosomi might belong and, in turn, if our understanding of the Bembidiini itself needed adjustment. These results are implied in Part I, but presented in detail in a separate paper, Part II. Phylogeny and Zoogeography, along with supplemental taxonomic information.

Full textAbstract:
The research examined whether performance by adult cochlear implant recipients on a variety of recognition and appraisal tests derived from real-world music could be predicted from technological, demographic, and life experience variables, as well as speech recognition scores. A representative sample of 209 adults implanted between 1985 and 2006 participated. Using multiple linear regression models and generalized linear mixed models, sets of optimal predictor variables were selected that effectively predicted performance on a test battery that assessed different aspects of music listening. These analyses established the importance of distinguishing between the accuracy of music perception and the appraisal of musical stimuli when using music listening as an index of implant success. Importantly, neither device type nor processing strategy predicted music perception or music appraisal. Speech recognition performance was not a strong predictor of music perception, and primarily predicted music perception when the test stimuli included lyrics. Additionally, limitations in the utility of speech perception in predicting musical perception and appraisal underscore the utility of music perception as an alternative outcome measure for evaluating implant outcomes. Music listening background, residual hearing (i.e., hearing aid use), cognitive factors, and some demographic factors predicted several indices of perceptual accuracy or appraisal of music. La investigación examinó si el desempeño, por parte de adultos receptores de un implante coclear, sobre una variedad de pruebas de reconocimiento y evaluación derivadas de la música del mundo real, podrían predecirse a partir de variables tecnológicas, demográficas y de experiencias de vida, así como de puntajes de reconocimiento del lenguaje. Participó una muestra representativa de 209 adultos implantados entre 1965 y el 2006. Usando múltiples modelos de regresión lineal y modelos mixtos lineales generalizados, se seleccionaron grupos de variables óptimas de predicción, que pudieran predecir efectivamente el desempeño por medio de una batería de pruebas que permitiera evaluar diferentes aspectos de la apreciación musical. Estos análisis establecieron la importancia de distinguir entre la exactitud en la percepción musical y la evaluación de estímulos musicales cuando se utiliza la apreciación musical como un índice de éxito en la implantación. Importantemente, ningún tipo de dispositivo o estrategia de procesamiento predijo la percepción o la evaluación musical. El desempeño en el reconocimiento del lenguaje no fue un elemento fuerte de predicción, y llegó a predecir primariamente la percepción musical cuando los estímulos de prueba incluyeron las letras. Adicionalmente, las limitaciones en la utilidad de la percepción del lenguaje a la hora de predecir la percepción y la evaluación musical, subrayan la utilidad de la percepción de la música como una medida alternativa de resultado para evaluar la implantación coclear. La música de fondo, la audición residual (p.e., el uso de auxiliares auditivos), los factores cognitivos, y algunos factores demográficos predijeron varios índices de exactitud y evaluación perceptual de la música.

RESUMEN
Se evaluó el comportamiento productivo de gallinas Rhode Island Rojas (RIR) y Plymouth Rock Barradas (PRB), durante el primer ciclo de postura, bajo las condiciones ambientales de la región del Altiplano en el estado de Michoacán, México. Para ello se utilizaron 26 gallinas doble propósito, distribuidas aleatoriamente en dos grupos: 13 RIR y 13 PRB de 20 semanas de edad, colocadas en jaulas individuales convencionales tipo batería; durante el período experimental (noviembre de 2019 a octubre de 2020), recibieron alimento comercial especial para gallinas en postura y agua, ambos ad libitum. Las variables bajo control fueron: peso vivo inicial (PVi), peso vivo final (PVf), consumo de alimento (CA), peso del huevo (PH), porcentaje de postura (%P), huevos por ciclo (HPC), masa de huevo (MH), índices morfométricos (IM), índices productivos (IP). Los resultados más relevantes en los genotipos RIR y PRB fueron: PVi y PVf, 2.019 vs. 2.160 kg y 2.105 vs. 2.300 kg respectivamente (P<0.05); CA, RIR 124.1 vs. PRB 131.8 g (P<0.05); PH y %P para RIR y PRB: 59.4 vs. 61.2 g, 82.5 vs. 64.8 % (P<0.05) respectivamente; HPC y MH: 287.3 vs. 226.8 y 17.217 vs. 13.721 kg para RIR y PRB (P<0.0001) en su orden. En conclusión, las gallinas del genotipo Rhode Island Rojas mostraron mejor comportamiento productivo que sus contemporáneas Plymouth Rock Barradas.
ABSTRACT
The productive behavior of Rhode Island Red (RIR) and Plymouth Rock Barradas (PRB) hens was evaluated during the first laying cycle under the environmental conditions of the Altiplano region in the state of Michoacán, Mexico. For this purpose, 26 dual-purpose hens were used, randomly distributed in two groups: 13 RIR and 13 PRB of 20 weeks of age, placed in individual conventional battery type cages; during the experimental period (November 2019 to October 2020), they received special commercial feed for laying hens and water, both ad libitum. The variables under control were: initial live weight (PVi), final live weight (PVf), feed consumption (CA), egg weight (PH), laying percentage (%P), eggs per cycle (HPC), egg mass (MH), morphometric indices (IM), productive indices (IP). The most relevant results in RIR and PRB genotypes were: PVi and PVf, 2.019 vs. 2.160 kg and 2.105 vs. 2.300 kg respectively (P<0.05); CA, RIR 124.1 vs. PRB 131.8 g (P<0. 05); PH and %P for RIR and PRB: 59.4 vs. 61.2 g, 82.5 vs. 64.8 % (P<0.05) respectively; HPC and MH: 287.3 vs. 226.8 and 17.217 vs. 13.721 kg for RIR and PRB (P<0.0001) in their order. In conclusion, hens of the Rhode Island Red genotype showed better productive performance than their Plymouth Rock Barradas contemporaries.

LABURPENA: Azken urteotan, adierazpen-askatasunaren eremuan interpretazio murriztaile bat egiteko joera agertu da, bai jurisprudentzia arruntean, bai konstituzioarenean. Hori nabarmena da sinboloen eta erakundeen babesaren eremuan: Zigor Kodean hainbat aurreikuspen jaso dira, Konstituzioaren aurkako delituei eskainitako titulu batean. Zigor-mota horien oinarrian, sinbolo eta erakunde horien kontzepzio sakralizatzailea dago, eta eduki anitzeko ondasun juridikoen identifikazioa eta aplikazio zabala. Horri gorroto-diskurtsoaren figura erantsi zaio batzuetan, baina testuingurutik aterata eta bereak dituen interpretazioirizpiderik gabe; hala, figura horren edukia esajeratuz, harekin zerikusirik ez duten egoeretan aplikatu da. Horretaz gain, epaitutako egitateak kasu-mota horien barruan definitzeko orduan, organo judizialek subjektibismo edo hunkiberatasun nabarmena erakutsi dute askotan, eta horrek asko baldintzatzen du egitateez egiten duten kalifikazioa. Horregatik, ondorioztatu da adierazpen-askatasuna alde batera geratzen dela, eta bere efikazia nabarmen murriztuta, baztertzen delako, funtsik gabe, erakundeak eta sinboloak kritikatzeko aukera. ABSTRACT: In the last few years, there has occurred a trend towards a restrictive interpretation of the scope of freedom of expression in both ordinary and constitutional case law. One of the areas in which this was most evident is the protection of symbols and institutions, which were the objects of a series of provisions in the Criminal Code with a whole title devoted to crimes against the Constitution. The application of this type of penalties has departed from a sacralizing conception of such symbols and institutions, and from the identification of legal assets of multiple content and expansive application. This has sometimes been accompanied with the use of the figure of hate speech, but out of context and without their own interpretative criteria, so that by exaggerating their content they end up been applied to situations that in fact have nothing to do with it. A significant judicial subjectivism or emotivism is added to them when it comes to define the facts to be judged, which strongly shapes the subsequent qualification of them. This leads to the conclusion that freedom of expression is shifted and its effectiveness substantially diminished in the name of an incorrect exclusion of institutions and symbols of the possibility of being criticized. RESUMEN: En los últimos años se ha producido una tendencia que apunta hacia una interpretación restrictiva del ámbito de la libertad de expresión en la jurisprudencia tanto ordinaria como constitucional. Uno de los terrenos en que esto se ha dado de modo más evidente ha sido el de la protección de los símbolos y las instituciones, objeto de una serie de previsiones en el Código Penal en un título dedicado a los delitos contra la Constitución. La aplicación de estos tipos penales ha partido de una concepción sacralizadora de tales símbolos e instituciones, y de la identificación de bienes jurídicos de contenido múltiple y aplicación expansiva. A ello se ha unido en ocasiones el recurso a la figura del discurso del odio, pero sacada de contexto y sin los criterios de interpretación que le son propios, de modo que exagerando su contenido acaba aplicándose a situaciones que en realidad no tienen que ver con ella. Se añade a lo anterior la frecuente presencia de un apreciable subjetivismo o emotividad por parte del órgano judicial a la hora de definir en este tipo de casos los hechos enjuiciados, lo que condiciona fuertemente la posterior calificación de los mismos. De ello se extrae como conclusión que la libertad de expresión se ve desplazada y su eficacia sustancialmente aminorada, en nombre de una incorrecta exclusión de las instituciones y los símbolos de la posibilidad de ser objeto de crítica.

<p>En este trabajo se evaluó el desempeño de dos metodologías, una microbiológica y una molecular basada en la amplificación por reacción en cadena de la polimerasa (PCR), para la detección de <em>Yersinia pseudotuberculosis </em>en heces de cuyes. La evaluación de cada una de las metodologías se realizó teniendo en cuenta su sensibilidad y especificidad analítica, así como su costo económico, tiempo y complejidad. La detección molecular de <em>Y. pseudotuberculosis </em>se realizó por PCR anidada usando iniciadores específicos para el gen de virulencia cromosomal <em>inv</em>, mientras que en los ensayos microbiológicos la identificación bacteriana se hizo mediante una batería comercial de perfiles bioquímicos<em>. </em>Se estandarizó un protocolo de amplificación en materia fecal, el cual redujo el efecto negativo que causan los inhibidores de la PCR presentes en muestras de esta naturaleza. La sensibilidad analítica más alta se observó con la metodología en la que se combinó preenriquecimiento, aislamiento microbiológico y PCR, con un rango de detección entre 1,5 x 104 y 1,5 x 103 unidades formadoras de colonias por gramo (ufc/g) de material fecal; mientras que la mayor sensibilidad obtenida en PCR anidada fue de 1,5 x 105 ufc/g de materia fecal. Tanto la metodología microbiológica como la molecular presentaron ventajas en los ensayos en los que se usó materia fecal estéril experimentalmente inoculada. Sin embargo, en muestras de materia fecal sin esterilizar la detección del microorganismo se dificultó al utilizar una única metodología, por lo que se sugiere combinar técnicas microbiológicas y moleculares para obtener un mejor desempeño diagnóstico. </p><p><strong><em> </em></strong></p><p><strong><em>Yersinia pseudotuberculosis </em></strong><strong>detection in feces of guinea pigs (<em>Cavia porcellus</em>) using microbiological and molecular methods </strong></p><p>The suitability of two methodologies, a conventional microbiological method and a molecular method, based on amplifications by Polimerase Chain Reaction (PCR) was evaluated for the detection of <em>Yersinia pseudotuberculosis </em>in feces of guinea pig.

This method was able to detect bacterial concentrations between 1.5 x 104 and 1.5 x 103 colony-forming units per gram (CFU/g) of feces, whereas the highest diagnostic sensitivity level obtained by nested PCR was 1.5 x 105 CFU/g of feces. Both, the molecular and the microbiological methodologies, had advantages with experimentally inoculated sterile feces. Since the detection of the microorganism on samples of non-sterilized feces was difficult using either method, the use of a combination of microbiological and molecular techniques is suggested to get a better diagnostic performance for the detection of this pathogen. </p><p> </p>

Abstract.Basic assembly to capture on curriculum design and development Skills, the Learning to Learn is essential for several reasons: first, because the educational paradigm of Lifelong Learning which enshrines the European Union, requires citizens to be suitable for acquiring an ever changing , available at various sources of information, especially that provided by virtual environments, and the ability to apply and use it indifferent contexts , knowledge being in a professional environment where they are going to make clear the acquisition that power. Moreover, this competition covers and covers a wide range of areas, dimensions and indicators of other skills that are essential, the Autonomous Learning goes beyond the cognitive aspects , having special relevance the emotional, something that becomes even more apparent given the interrelated and inclusiveness that characterizes the Basic Skills.The European Higher Education promotes a type of learning in more autonomous and flexible student who required him, among other things, but as a priority , knowledge , control and application of cognitive and emotional factors brought into play during the learning processes. In this paper , we begin by defining the concept and the basic guidelines of this competition lines from psychological approaches that deal with the Meta Cognition, until the underlying socioeconomic and sociopolitical fonts in documents and OECD guidelines (draft DESECO), European Union (program working groups 2010 and 2020), or the Ministry of Education itself . The core of this paper consists in selecting a set of fields , dimensions , sub - dimensions and indicators of competency assessment to learning that will help teachers to design and develop their Schedules and teaching units in forms of Assessment Objectives and Indicators . We end by outlining what the best organizational strategies at plant level , methodological classroom level and individual as well as the different types of activities , materials and resources (as we saw in the seven modules and eight) that are better suited for work this important competition.Keywords: learning to learn, teaching programs , assessment indicators , methodological and organizational strategies.Resumen.Del conjunto de Competencias Básicas a plasmar en el diseño y desarrollo curricular, la de Aprender a Aprender es esencial por varios motivos: en primer lugar, porque con el paradigma educativo del Lifelong Learning que consagra la Unión Europea, exige que los ciudadanos se adecuen a la adquisición de un conocimiento cada vez más cambiante, disponible en varias fuentes de información, especialmente la que proporcionan los entornos virtuales, y con la capacidad de aplicarlo y utilizarlo indiferentes contextos, siendo en el entorno profesional donde más se va a hacer evidente la adquisición de dicha competencia. Por otro lado, esta competencia abarca y engloba un amplio conjunto de ámbitos, dimensiones e indicadores de otras competencias que son esenciales, el Aprendizaje Autónomo va más allá de los aspectos cognitivos, teniendo especia relevancia los aspectos emocionales, algo que se hace aún más patente dado el carácter interrelacionado e integrador que caracteriza las Competencias Básicas.El Espacio Europeo de Educación Superior, promueve un tipo de aprendizaje en el alumno más autónomo y flexible que exigirá de él, entre otras cosas, aunque de forma prioritaria, el conocimiento, control y aplicación de los factores cognitivos y emocionales puestos en juego durante los procesos de aprendizaje. En la presente ponencia, comenzaremos delimitando el concepto y las líneas directrices básicas de esta competencia, desde los enfoques psicológicos que tienen que ver con la Meta Cognición, hasta las fuentes socio políticas y socio económicos subyacentes en los documentos y directrices de la OCDE (proyecto DESECO), de la Unión Europea (grupos de trabajo del programa 2010 y 2020), o el propio Ministerio de Educación. El núcleo central de la presente ponencia consiste en la selección de una batería de ámbitos, dimensiones, sub-dimensiones e indicadores de evaluación de la competencia de Aprender a Aprender que servirán al profesorado para el diseño y el desarrollo de sus Programaciones y Unidades Didácticas en formas de Objetivos e Indicadores de Evaluación. Finalizaremos esbozando cuáles son las mejores estrategias organizativas a nivel de centro, metodológicas a nivel de aula e individual, así como los diferentes tipos de actividades, materiales y recursos didácticos (según lo que vimos en los módulos siete y ocho) que mejor se adecuan para trabajar esta competencia tan importante.Palabras Clave: aprender a aprender; programaciones didácticas; indicadores de evaluación; estrategias metodológicas y organizativas.

"FLT3 Inhibitors Are Promising Salvage Therapy for Relapsed or Refractory Acute Myeloid Leukemia (AML) in Patients with FLT3-ITD Mutations,." Blood 118, no. 21 (November 18, 2011): 3623. http://dx.doi.org/10.1182/blood.v118.21.3623.3623.
Full textAbstract:
Abstract Abstract 3623 Background: The FMS-like tyrosine kinase (FLT3) is a transmembrane tyrosine kinase that belongs to the class III family of receptor tyrosine kinases. Internal tandem duplication (ITD) in the juxtamembrane domain of the FLT3 is found in approximately 15–30% of AML cases and its constitutive activation of kinase cascade is considered to contribute to leukemogenesis. The prognosis for AML patients (pts) with FLT3-ITD mutation is significantly worse than that with wild-type FLT3 pts and largely a result of a high relapse rate with poor response to salvage therapy. Recently, several FLT3 inhibitors (FLT3i) have been introduced to clinical trials and some of them are exhibiting clinical efficacy. Data are lacking on whether the use of FLT3i as salvage therapy for relapsed or refractory AML pts with FLT3-ITD mutations will improve long-term outcomes and how they compare to salvage therapy with standard chemotherapy. Aim: To determine the long-term efficacy of FLT3 inhibitors when used as first salvage therapy for refractory and relapsed AML in pts with FLT3-ITD mutations and compare it with that of conventional chemotherapy. Methods: We conducted a retrospective study of 120 pts with AML having FLT3-ITD mutation who had relapsed after or exhibited disease refractory to front-line therapy, thus received salvage therapy in various clinical trials. The cohort was divided into two groups that received a salvage regimen consisting of 1) conventional cytotoxic chemotherapy or 2) one of several FLT3i (e.g., sorafenib, PKC-412, CEP-701, AC-220, KW-2449, AP24534) either alone or in combination with chemotherapy. Pts who had received FLT3i as part of their front-line therapy were excluded from the study. Response to salvage therapy was classified according to the International Working Group (including CR, CRp, or CRi). Results: Between August 1995 and June 2011, 120 pts were treated, of which 75 received conventional chemotherapy (Conventional group; 71/75 were Ara-C based) and 45 received a FLT3i (FLT3i group). Among them, 43 pts were refractory to induction (Conventional = 26 [35%] vs FLT3i = 17 [38%]) and 77 had relapsed disease (Conventional = 49 [65%] vs FLT3i = 28 [62%]). The median duration of 1st remission for the latter group was 8.9 months. The median follow-up durations in the Conventional and the FLT3i groups were 71.5 weeks and 62.3 weeks, respectively (p=0.73). Baseline characteristics, such as age, sex, ECOG performance status and other laboratory parameters were similar in both groups. The number of pts who received stem cell transplant (SCT) as part of the salvage therapy was not statistically different (Conventional = 21/75 [28%] vs FLT3i = 11/45 [24%]; p = 0.67). Of those pts, SCT was performed while they were in CR in 9/21 pts in the Conventional and 2/11 in the FLT3i group (p=0.18). SCT was performed in 1st CR only in one patient in the Conventional and none in the FLT3i group. Response to the salvage therapy (CR, CRp and CRi) in the two groups was not statistically different (16/75 [21%] in conventional group vs 9/45 [20%] in the FLT3i group; p=0.41). The median overall survival (OS) was 41 weeks in the Conventional and 58 weeks in the FLT3i group (p=0.312). There was no significant difference in OS by treatment arm when analyzed separately for older (age above 60) and younger pts. Of the FLT3i group, 31/45 [69%] received FLT3i alone and it was combined with chemotherapy in 14/45 [31%]. The median OS was significantly better when FLT3i was combined as opposed to FLT3i monotherapy (median OS 102 weeks vs 49 weeks; p<0.05); the duration was also superior to that in Conventional group (41 weeks; p<0.05). In the pts whose initial CR duration was shorter than 12 months or who never had a CR with front-line therapy (N=88), the median OS was significantly better in FLT3i group (N=25) than that in the Conventional group (N=63) (58 weeks vs 33 weeks; p<0.01). Conclusions: Salvage therapy including a FLT3 inhibitor appears to be beneficial for relapsed or refractory AML pts with FLT3-ITD mutation, especially when combined with cytotoxic chemotherapy. Pts who never experienced a CR to front-line therapy or whose CR duration was less than 12 months benefited the most from FLT3 inhibitor therapy. Although further prospective studies are necessary to confirm these results, they suggest that a FLT3 inhibitor should be included in salvage regimens for relapsed or refractory AML pts with FLT3-ITD mutation.

Transportation is a sector that contributes significantly to CO2 gas emissions and has the potential to continue to increase along with the addition of fossil fuel vehicles. Indonesia has plans to switch to electric vehicles as an alternative to reduce greenhouse gas (GHG) emissions from the transportation sector. The battery is an important component of an electric vehicle, and there are several alternative technologies that can be used. This paper simulates the selection of a suitable battery from various type of batteries, including Lead-acid (PbA), Nickel Metal Hydride (NiMH) and Lithium-ion (Li-ion). The selection is made using the weighted objective method by presenting 5 criteria: energy density; emissions generated for battery production; energy factor of the manufacturing process; availability of critical raw materials required for cathodes and anodes; and availability of recycling facilities. Supporting data to determine the magnitude of each criterion is obtained from literature reviews. The analysis and comparison was carried out by giving weight to the assessment based on the data obtained. The results of calculations carried out in the paper show that the Lead-acid battery is a viable option for use at current time.However, if Indonesia already has NiMH and Li-ion battery recycling facilities, or is capable of producing Lithium-ion batteries, then the criteria and calculation factors can be added and improved.

Indonesia merupakan negara yang memiliki berbagai jenis sumber daya energi dalam jumlah yang cukup melimpah. Wilayah Indonesia akan selalu disinari matahari selama 10 - 12 jam dalam sehari. Data Dirjen Listrik dan Pengembangan Energi pada tahun 1997, kapasitas terpasang listrik tenaga surya di Indonesia mencapai 0,88 MW dari potensi yang tersedia 1,2 x 109 MW. Kebanyakan panel surya dipasang permanen dengan sudut elevasi yang tetap (fixed elevating angles). Hal ini menyebabkan panel surya tersebut tidak dapat menyerap radiasi matahari secara optimal. Penyerapan radiasi matahari akan optimal jika arah radiasi matahari tegak lurus terhadap permukaan bidang panel surya. Penulis tertarik untuk merancang dan membuat alat yang dapat dipergunakan untuk menempelkan panel sel surya tetap dalam kondisi intensitas matahari yang maksimum. Dalam hal ini, menggunakan satu sumbu. dengan telah dibuatnya alat penggerak mekanik satu sumbu pada solar panel ini, penulis dapat memberikan gambaran tentang pembangkit listrik tenaga surya kepada masyarakat. Selain itu dengan adanya penggerak mekanik pada solar panel ini, solar panel bisa lebih besar menghasilkan tegangan pada baterai daripada solar panel tanpa penggerak. Dan dari percobaan menggunakan penggerak mekanik satu sumbu ini menghasilkan tegangan di pukul 08.00 pada baterai nominal sebesar 2,04V hari pertama, 2,05V hari kedua dan 2,03V hari ketiga dan di akhir perhitungan pukul 16.00 tegangan pada baterai menujukan nominal sebesar 11,18V hari pertama, 11,27V hari kedua dan 11,3V hari ketiga.Kata Kunci : Solar Panel, Tipe BCT30-12, Penggerak Satu Sumbu Indonesia is a country that has different kinds of energy resources in sufficient quantities abundant. then Indonesia will be always exposed to the sun for 10-12 hours a day. Data Director General of Electricity and Energy Development in 1997, the installed capacity of solar power in Indonesia reached 0.88 MW of the available potential of 1.2 x 109 MW. Most solar panels are installed permanently at a fixed elevation angle (fixed elevating angles). This causes the solar panels can not absorb solar radiation optimally. Absorption of solar radiation would be optimal if the solar radiation direction perpendicular to the surface of solar panel field. Writers interested in designing and creating tools that can be used to attach the solar panels remain in a state of maximum intensity of the sun. In this case, using a single axis. to have made a mechanical actuator on the solar panel one axis, the author can give an idea of solar power plants to the public. In addition to the mechanical drive on the solar panels, the solar panels generate voltage can be larger than the solar panel to the battery without driving. And from experiments using mechanical drive one axis produces a voltage at 08.00 at a total nominal battery 2,04V first day, 2,05V 2,03V second day and third day and at the end of the calculation 16.00 nominal voltage of the battery addressed by 11,18V the first day, 11,27V 11,3V second day and third day.keyword : Solar Panel, Type BCT30-12, Activator One Wick

O presente estudo teve como objetivo analisar os níveis hormonais, as alterações histopatológicas e os agentes etiológicos encontrados na piometra aberta e fechada em cadelas. Foram colhidas 30 amostras de fêmeas ovariohisterectomizadas em clínicas veterinárias da cidade de Curitiba, no Estado do Paraná, no período de outubro de 2002 a maio de 2003. Procedeu-se a exames bacteriológicos, análises histopatológicas dos cornos uterinos e dosagem hormonal da progesterona e do estradiol pela quimioluminescência. A bactéria isolada em maior porcentagem (36%) foi a Escherichia coli, e a alteração histológica de hiperplasia cística endometrial encontrada variou do grau I ao grau III. A proporção entre a progesterona e estradiol teve uma variação significativa nos dois tipos de piometra, porém não foi possível relacionar o agente etiológico, o tipo de lesão e a dosagem hormonal com o tipo de piometra, aberta ou fechada. Histopathological, hormonal, bacterial evaluation in the bitch pyometra Abstract The aim of the present study was to carry out an evaluation of the hormone levels, the histological changes and the etiological agents found in the open and closed pyometra. The uterine horns were collected from 30 bitches subjected to ovariectomy in different veterinary clinics from Curitiba, State of Parana, during the period of October 2002 to May, 2003. Bacteriological cultures, histological analysis and assays of progesterone and estradiol by the chemoluminescent method were performed. Escherichia coli showed to be the most frequent (36%) of the isolated bateria. It has been found the histological analysis that cystic endometrial hyperplasia varied from type I to type III. The progesterone/ estradiol ratio showed a significant variation in regard to the two types of piometra. However, it was not possible to corrrelate the etiological agent, the lesion and the hormonal levels with the open or closed pyometra.

Resumo: Neste artigo, pretendemos utilizar os dados de Vialli (2013), que reuniu, em sua tese de doutoramento, cerca de cem formas de composição reduplicativa em português, à luz do modelo de morfologia construcional (MC) originalmente proposto por Booij (2005, 2007, 2010). Esse modelo aplica a gramática das construções (GOLDBERG, 1995) ao componente morfológico, analisando as formações lexicais por meio de esquemas e subesquemas que representam o pareamento entre o polo formal e o polo semântico de palavras morfologicamente complexas. Entendendo que a reduplicação verbal (composição ViVi) pode ser satisfatoriamente descrita com os instrumentos da MC, procuramos explicar, formal e semanticamente, construções como “bate-bate” (“bater repetidamente”, “carrinho do parque de diversões”) e “agarra-agarra” (“agarrar repetidas vezes”), mostrando as motivações morfológicas e as extensões de significado desse tipo de formação e distinguindo-o da repetição, fenômeno que ocorre em nível sintático.Palavras-chave: Morfologia. Formação de palavras. Construção. Reduplicação. Composição.Abstract: In this article, we intend to explain the Vialli (2013)”s data – which met, in her doctoral thesis, about a hundred forms of reduplicative compounding in Brazilian Portuguese – based on constructional morphology model (MC), originally proposed by Booij (2005 2007, 2010). This model applies construction grammar (GOLDBERG, 1995) to morphology component, analyzing the lexical formations through schemes and subschemas representing the pairing between the formal pole and the semantic pole of morphologically complex words. Understanding that the verbal reduplication (composition ViVi) can be satisfactorily described with the instruments of MC, we try to explain, formal and semantically, formations such as "bat-bate" ("hit repeatedly"; "playground toy") and "agarra-agarra" (grab repeatedly), showing the morphological motivations and meaning extentions of this type of word-formation process and distinguishing it from the repetition phenomenon that occurs in the syntatic level.

Full textAbstract:
A região estudada é composta por rochas do Maciço Granítico Serra do Paratiú MGSP, rochas metamórficas do Complexo Turvo-Cajati (ou metarritmitos Iguape), formações sedimentares Plio-Pleistocênicas do Grupo Mar Pequeno (Formação Cananéia e, muito subordinadamente, as Formações Pariqüera-Açu e Ilha Comprida) e coberturas holocênicas de origem continental, marinha e mista. O MGSP, Neoproterozóico Eopaleozóico, está inserido na Plataforma Sul-Americana, no contexto geotectônico do embasamento cristalino sul-sudeste brasileiro (Bloco Iguape), pertencendo à Suíte Intrusiva Serra do Mar. Acha-se intrudido em rochas metamórficas do Complexo Turvo-Cajati (Paleoproterozóico), onde, localmente, junto ao contato com o corpo granítico, verifica-se biotita-cordierita hornfels denotando metamorfismo de contato. Constitui-se em um corpo, circunscrito, de forma levemente ovalada, com aproximadamente 70 km² de área aflorante; muito homogêneo, onde predomina biotita monzogranito, porfirítico, de cor cinza claro e, subordinadamente, biotita sienogranito. É fracamente peraluminoso, do tipo subsolvus, e coloca-se nos termos finais da série cálcioalcalina. A hipótese de que o Granito Serra do Paratiú seja pós-orogênico é reforçada pelas evidências de campo (forma do corpo, metamorfismo de contato) e petroquímicas. Os dados petroquímicos permitem posicionálo como um granito mais pertinente à classe dos granitos pós-colisionais, variável de pós-tectônico a anorogênico, com dados composicionais, relativos a alguns elementos (Y, Nb, Rb, Zr) e óxidos (SiO2, K2O), que permitem visualizá-lo ora como tipo I reduzido e ora como tipo A, formado por fusão da crosta inferior, altamente fracionada, à semelhança do que ocorre com os granitos australianos Ackley e Sandy Cape, cujas características geoquímicas são compatíveis com os granitos do tipo A, mas geológica e petrograficamente são, respectivamente, granitos do tipo I e S. Os granitos da Suíte Serra do Mar, da qual o MGSP faz parte, apresentam idades radiométricas de 580 ± 20 Ma. Concomitantemente ao trabalho de mapeamento geológico desse Maciço Granítico efetuou-se, em seu domínio, a coleta de amostras de sedimentos ativos de corrente, que foram analisadas para os elementos Cu, Zn, Pb, Li, Mo, Bi, F e Sn, e de concentrados de bateia, que foram submetidos a análises mineralógicas. A integração de todos os dados obtidos durante esta pesquisa permitiu concluir que o MGSP corresponde a um corpo estéril, do ponto de vista de exploração mineral, e que sua esterilidade deve-se a um conjunto de situações desfavoráveis, tais como: ausência de um protólito enriquecido em metal; não desenvolvimento de uma fase de pré-concentração durante a evolução magmática; presença de um conjunto de minerais acessórios cafêmicos e seqüestradores de metal na fase magmática precoce (ilmenita, magnetita, etc); e liberação precoce da fase aquosa, prejudicando qualquer compensação e sucesso de concentração hidrotermal. PETROGRAPHY, PETROCHEMISTRY AND METALLOGENY OF THE SERRA DO PARATIÚ GRANITE, CANANÉIA, SÃO PAULO STATE Abstract The studied region is made up of rocks of the Serra do Paratiú Granite Massif SPGM, metamorphic rocks of Turvo-Cajati Complex (metarhytmites Iguape), sedimentary formation Plio-Pleistocenic of Mar Pequeno Group (Cananéia Formation and, subordinated, Pariqüera-Açú and Ilha Comprida formations) and holocenic sediments of continental, marine and mixed origin. The SPGM Neoproterozoic Eopaleozoic is inserted in the South American Platform, in the geotectonic complex of the Brazilian south-southeast crystalline basement (Iguape Block), integrating the Serra do Mar intrusive suite. It is intruded in the metamorphic rocks of the Turvo- Cajati complex (Paleoproterozoic), where locally there are contact metamorphic rocks, mainly biotite-cordoerite hornfels. It is a lightly oval shaped circumscribed and discordant body with approximately 70 km² of outcrop area, relatively homogeneous constituted by biotite-monzogranite, porphyritic, grey color and subordinated botitesienogranite. The SPGM is weakly peraluminous, of subsolvus type and belongs to the end of a chalcalkaline series. The hypothesis that Serra do Paratiú Granites is post-orogenic is reinforced by petrochemical data and field evidence (shape of the body, contact metamorphism). The petrochemical data allows to put the SPGM as post-collision granite. Post-tectonic to anorogenic with data of some elements (Y, Nb, Rb, Zr) and oxides (SiO2, K2O) that allow to consider it as I or A type, formed by fusion of high fractionated inferior Crust. This fact is similar to those of hybrid us granites of Australia (Ackley and Sandy Cape), which geochemical characteristics are compatible with type A granites, but geological and aerographical data suggest that they are respectively of type I and S. The granites of Serra do Mar Suite including the SPGM present radiometric ages of 580 ± 20 Ma. Concomitantly to the work of geological mapping of this granite massif, samples of active stream sediments were taken, which were analyzed for Cu, Pub, Zn, Li, Mo, Bi, F and Son. Panned concentrated samples also were taken to mineralogical analysis. The integration of all data obtained during this research suggests that the SPGM is a sterile granite due to several unfavorable situations, such as: absence of a protoplast enriched with metal; no development of pre-concentration phase during the magmatic evolution; presence of a group of cafemic and metal kidnappers accessory minerals during early-magmatic phase (ilmenite, magnetite, etc,), and precocious liberation of a volatile phase, not allowing hydrothermal concentration.
