Strategi Pembelajaran PQ4R: Pengembangan Buku Strategi Membaca Siswa Sekolah Dasar Berbasis Penguatan Pendidikan Karakter

Membaca adalah salah satu dari empat keterampilan dasar berbahasa yang perlu di miliki oleh masyarakat terutama bagi peserta didik, tidak hanya sebagai salah satu cara tersampaikannya informasi melainkan proses metakognitif yang bisa menjadi kebiasaan dan karakter individu. Tujuan dari artikel ini adalah mendeskripsikan salah satu strategi pembelajaran membaca bagi siswa di sekolah dasar dalam rangka pengembangan pembuatan buku strategi membaca siswa sekolah dasar berbasis penguatan Pendidikan karakter. PQ4R (Preview, Question, Read, Reflect, Recite, Review) merupakan salah satu strategi membaca yang efektif digunakan oleh guru untuk proses pembelajaran di kelas dengan tujuan selain memahami isi bacaan, memberi kesempatan siswa berpikir kritis dan kreatif dengan membiasakan menemukan masalah dan solusi sendiri. Selain karakter pembelajar yang didapatkan oleh siswa pembiasaan belajar mandiri menjadi salah satu ciri dari strategi PQ4R. Penerapan PQ4R juga memberikan kesempatan kepada kita untuk mengingat informasi itu dalam jangka waktu yang lebih lama daripada membaca yang biasa kita lakukan. Dengan demikian, membaca dengan menggunakan model ini berarti menghemat waktu dan tenaga guna memahami informasi penting yang kita butuhkan

A survey of X-ray emission from 100 kpc radio jets

We have completed a Chandra snapshot survey of 54 radio jets that are extended on arcsec scales. These are associated with flat spectrum radio quasars spanning a redshift range z=0.3 to 2.1. X-ray emission is detected from the jet of approximately 60% of the sample objects. We assume minimum energy and apply conditions consistent with the original Felten-Morrison calculations in order to estimate the Lorentz factors and the apparent Doppler factors. This allows estimates of the enthalpy fluxes, which turn out to be comparable to the radiative luminosities.Comment: Conference Proceedings IAU Symposium No. 313, Extragalactic jets from every angle, pp. 219-224, 4 figure

Mitochondrial DNA Variations in Colombian Creole Sheep Confirm an Iberian Origin and Shed Light on the Dynamics of Introduction Events of African Genotypes

The genetic origins and diversity of Creole sheep from five regions of Colombia were investigated based on mitochondrial DNA (mtDNA) variations across 89 sequences from five breeds: one wool Creole sheep (CL) and four hair Creole sheep, including Ethiopian (OPCE), Sudan (OPCS), Pelibuey (OPCP) and Wayúu (OPCW). A global comparison was done using 62 haplotypes from Iberian, African, Indian, Caribbean, Mexican, Caucasian and European sheep based on sequences retrieved from GenBank. This study aimed to identify the maternal origin of Colombian Creole sheep and their genetic relationships at a global level. The results showed 31 different haplotypes from Colombian Creole sheep, which can be assigned to maternal lineage B, the most common lineage found in European sheep breeds and the only one found in several Iberian breed (e.g., Churra, Spanish Merino) that most likely participated in the Creole formation. Additional analyses showed that wool and hair sheep retained a broad genetic identity despite being geographically separated. The global-level phylogenetic analysis revealed that Colombian Creole sheep belong to a distinct and defined genetic lineage that is likely the result of a founder effect with ecotypes of Iberian descent and the subsequent introduction of foreign breeds. This is consistent with historical reports on the presence of sheep in South America and, particularly, Colombia

Polarimetry and the High-Energy Emission Mechanisms in Quasar Jets. The Case of PKS 1136-135

Since the discovery of kiloparsec-scale X-ray emission from quasar jets, the physical processes responsible for their high-energy emission have been poorly defined. A number of mechanisms are under active debate, including synchrotron radiation, inverse-Comptonized CMB (IC/CMB) emission, and other Comptonization processes. In a number of cases, the optical and X-ray emission of jet regions are inked by a single spectral component, and in those, high- resolution multi-band imaging and polarimetry can be combined to yield a powerful diagnostic of jet emission processes. Here we report on deep imaging photometry of the jet of PKS 1136$-$135 obtained with the {\it Hubble Space Telescope.} We find that several knots are highly polarized in the optical, with fractional polarization $\Pi>30$. When combined with the broadband spectral shape observed in these regions, this is very difficult to explain via IC/CMB models, unless the scattering particles are at the lowest-energy tip of the electron energy distribution, with Lorentz factor $\gamma \sim 1$, and the jet is also very highly beamed ($\delta \geq 20$) and viewed within a few degrees of the line of sight. We discuss both the IC/CMB and synchrotron interpretation of the X-ray emission in the light of this new evidence, presenting new models of the spectral energy distribution and also the matter content of this jet. The high polarizations do not completely rule out the possibility of IC/CMB optical-to-X-ray emission in this jet, but they do strongly disfavor the model. We discuss the implications of this finding, and also the prospects for future work.Comment: 14 pages, 8 figures, ApJ in pres

Desarrollo de un sistema de información para el Comité Local para la Prevención y Atención de Desastres de Tuluá

El trabajo que se presenta tuvo como propósito, desarrollar un sistema de información bajo la Web que permite la gestión de información en el Comité Local para la Prevención y Atención de Desastres (CLOPAD). Igualmente, pretende apoyar a la comunidad, y a los evaluadores del comité en particular, con una herramienta que pueda ser utilizada en situaciones de desastre en las labores de atención y/o evaluación de daños y análisis de necesidades (EDAN). Por otro lado, se desarrolló una aplicación móvil que permite el registro de la información de mayor relevancia en el lugar del desastre, esto, con el fin de facilitar la captura de datos en sitio, dado que las condiciones de este no siempre son las más adecuadas. Finalmente, se adecuo el sistema con el fin de permitir visualizar información de desastres a través de un mapa en el cual el CLOPAD, la comunidad en general y demás entidades interesadas, puedan consultar de manera gráfica los desastres que ocurren en la ciudad. El sistema mencionado es de gran ayuda para los miembros del CLOPAD, ya que el acceso y almacenamiento de la información más relevante acerca de los desastres y los daños que este ocasiona, se puede realizar desde cualquier lugar, logrando así el mejoramiento en la calidad de la atención de personas afectadas.

The endothelial cell markers von Willebrand Factor (vWF), CD31 and CD34 are lost in glomerulonephritis and no longer correlate with the morphological indices of glomerular sclerosis, interstitial fibrosis, activity and chronicity.

Endothelial cells (ECs) are active participants of an inflammatory process in glomeruli. EC damage has been shown to play an important role in the progression of glomerulonephritis (GN). The degree of glomerular and peritubular capillary loss in models of progressive renal disease correlates with the severity of glomerulosclerosis and interstitial fibrosis. The aim of our study was to analyze the association of vWF, CD31 and CD34 immunoreactivity with the morphological indices of glomerular sclerosis, interstitial fibrosis, activity and chronicity in GN. A cross-sectional study of 22 patients with GN was conducted. Conventional stains (hematoxylin-eosin, periodic acid Schiff and Trichrome GĂśmĂśri stains) and immunohistochemistry (vWF, CD31 and CD34) were employed on kidney biopsies. Activity and chronicity of GN, as well as glomerular segmental sclerosis and interstitial fibrosis, were evaluated according to a scoring system initially used for lupus nephritis and antineutrophil-cytoplasmic-antibody-associated vasculitis. Immunohistochemistry was assessed using a semi-quantitative score. Statistical analysis was performed using EpiInfo 6.04. The mean patient age was 46.68+/-14.09; 14 patients were male, and eight were female. Performing Spearman's rank correlation test, no correlation was found between each marker and glomerular segmental sclerosis, interstitial fibrosis, activity and chronicity, which suggests a loss of these markers and microvasculature involvement

A Pilot Study of Nuclear Instability in Archived Renal and Upper Urinary Tract Tumours with Putative Ochratoxin Aetiology

DNA ploidy measurement has been applied uniquely to wax-embedded tissue of primary renal cell and metastatic tumours of a key experimental researcher on porcine ochratoxicosis, a control, and four transitional cell carcinomas from cases of Balkan endemic nephropathy. Primary renal tumour was diploid, and hyperdiploid metastasis was within the lower ploidy range for typical renal cell carcinoma. Three Balkan primary tumours showed extensive aneuploidy indicating marked nuclear instability, similar to model rat renal carcinoma caused by ochratoxin A. In contrast, much less nuclear instability in the putative occupational ochratoxicosis case fitted poorly with the ochratoxin A model
