ABSTRACT The purpose of this study is three. First, it describes the reading skills of news comprehension of VIII grade students of SMP Negeri 3 Solok. Second, describe the news text writing skills. Third, describe the correlation of reading news comprehension with news writing skills. This type of research is quantitative with descriptive methods. The design used in this study is correlational design. The population of this study was students of class VIII of SMP Negeri 3 Solok. The sample in this study was determined by proportional random sampling 15% of the population. The data of this study were in the form of scores on the reading comprehension test results of news comprehension and scores on the results of writing news text skills. This research instrument is an objective test to measure reading comprehension skills of news and performance tests to measure news text writing skills. Three results of this study. First, the reading skills of news comprehension in good qualifications (B) with an average grade of 78.56. Secondly, news writing skills in good qualifications (B) with an average of 77.78. Third, there is a correlation between reading comprehension and news writing skills with news text with n-1 degrees of freedom at a 95% confidence level. T value (3.77) is greater than t table (1.72), that is tcount> t table (3.77> 1.72), thus H0 is rejected and H1 is accepted because the test results prove that tcount is greater than t table.

ABSTRACT The purpose of this research there are three. First, describe the environmental field vocabulary mastery of grade VIII SMP Negeri Padang 18. Second, it describes the writing skills text beritasiswa class VIII SMP Negeri Padang 18. Third, vocabulary mastery correlation describes the environmental field with the text of the news writing skills of students of class VIII SMP Negeri Padang 18. The theory associated with this research is a theory about the writing skills (a), (b) the text of the news, and (c) mastery of the vocabulary of the field of the environment. This research type is quantitative descriptive method. The design used is a korelasional design. Population research is grade VIII SMP Negeri Padang 18 listed on the school year 2018/2019, namely 362 students. The research sample is determined by proportional random sampling of 20% of the population, namely 72 students. Research data in the form of score vocabulary mastery test results of the environmental field and score the writing skills test result text news. The data obtained through two types of tests i.e. objective tests to measure mastery of the vocabulary of the field of environmental and performance tests for measuring writing skills text news. Based on the results of the study, it was concluded that vocabulary knowledge is correlated with writing skills text news. The better knowledge of vocabulary will be the better text news writing skills anyway. Thus, for the skilled writing text news grade VIII SMP Negeri Padang, 18 required mastery of the vocabulary.

It has repeatedly been show that with conventional electron microscopes very fine electron probes can be produced, therefore allowing various micro-techniques such as micro recording, X-ray microanalysis and convergent beam diffraction. In this paper the function and performance of an SIEMENS ELMISKOP 101 used as a scanning transmission microscope (STEM) is described. This mode of operation has some advantages over the conventional transmission microscopy (CTEM) especially for the observation of thick specimen, in spite of somewhat longer image recording times.Fig.1 shows schematically the ray path and the additional electronics of an ELMISKOP 101 working as a STEM. With a point-cathode, and using condensor I and the objective lens as a demagnifying system, an electron probe with a half-width ob about 25 Å and a typical current of 5.10-11 amp at 100 kV can be obtained in the back focal plane of the objective lens.

Type Detector

A cylindrical mirror analyser (CMA) has been built with a parallel recording detection system. It is being used for angular resolved electron spectroscopy (ARES) within a SEM. The CMA has been optimised for imaging applications; the inner cylinder contains a magnetically focused and scanned, 30kV, SEM electron-optical column. The CMA has a large inner radius (50.8mm) and a large collection solid angle (Ω > 1sterad). An energy resolution (ΔE/E) of 1-2% has been achieved. The design and performance of the combination SEM/CMA instrument has been described previously and the CMA and detector system has been used for low voltage electron spectroscopy. Here we discuss the use of the CMA for ARES and present some preliminary results.The CMA has been designed for an axis-to-ring focus and uses an annular type detector. This detector consists of a channel-plate/YAG/mirror assembly which is optically coupled to either a photomultiplier for spectroscopy or a TV camera for parallel detection.

Acid Anhydrides

Embedding media based upon an epoxy resin of choice and the acid anhydrides dodecenyl succinic anhydride (DDSA), nadic methyl anhydride (NMA), and catalyzed by the tertiary amine 2,4,6-Tri(dimethylaminomethyl) phenol (DMP-30) are widely used in biological electron microscopy. These media possess a viscosity character that can impair tissue infiltration, particularly if original Epon 812 is utilized as the base resin. Other resins that are considerably less viscous than Epon 812 now are available as replacements. Likewise, nonenyl succinic anhydride (NSA) and dimethylaminoethanol (DMAE) are more fluid than their counterparts DDSA and DMP- 30 commonly used in earlier formulations. This work utilizes novel epoxy and anhydride combinations in order to produce embedding media with desirable flow rate and viscosity parameters that, in turn, would allow the medium to optimally infiltrate tissues. Specifically, embeding media based on EmBed 812 or LX 112 with NSA (in place of DDSA) and DMAE (replacing DMP-30), with NMA remaining constant, are formulated and offered as alternatives for routine biological work.Individual epoxy resins (Table I) or complete embedding media (Tables II-III) were tested for flow rate and viscosity. The novel media were further examined for their ability to infilftrate tissues, polymerize, sectioning and staining character, as well as strength and stability to the electron beam and column vacuum. For physical comparisons, a volume (9 ml) of either resin or media was aspirated into a capillary viscocimeter oriented vertically. The material was then allowed to flow out freely under the influence of gravity and the flow time necessary for the volume to exit was recored (Col B,C; Tables). In addition, the volume flow rate (ml flowing/second; Col D, Tables) was measured. Viscosity (n) could then be determined by using the Hagen-Poiseville relation for laminar flow, n = c.p/Q, where c = a geometric constant from an instrument calibration with water, p = mass density, and Q = volume flow rate. Mass weight and density of the materials were determined as well (Col F,G; Tables). Infiltration schedules utilized were short (1/2 hr 1:1, 3 hrs full resin), intermediate (1/2 hr 1:1, 6 hrs full resin) , or long (1/2 hr 1:1, 6 hrs full resin) in total time. Polymerization schedules ranging from 15 hrs (overnight) through 24, 36, or 48 hrs were tested. Sections demonstrating gold interference colors were collected on unsupported 200- 300 mesh grids and stained sequentially with uranyl acetate and lead citrate.

Structure Properties

Trace constituents, which can be very loosely defined as those present at concentration levels below 1 percent, often exert influence on structure, properties, and performance far greater than what might be estimated from their proportion alone. Defining the role of trace constituents in the microstructure, or indeed even determining their location, makes great demands on the available array of microanalytical tools. These demands become increasingly more challenging as the dimensions of the volume element to be probed become smaller. For example, a cubic volume element of silicon with an edge dimension of 1 micrometer contains approximately 5×1010 atoms. High performance secondary ion mass spectrometry (SIMS) can be used to measure trace constituents to levels of hundreds of parts per billion from such a volume element (e. g., detection of at least 100 atoms to give 10% reproducibility with an overall detection efficiency of 1%, considering ionization, transmission, and counting).
