The lack of leader strategy in communicating well to ASN, the lack of leadership attitude in giving attention and motivating ASN work and the lack of work communication among fellow employees resulted in less than optimal ASN performance. This research was conducted to determine the Effect of Leadership and Work Communication on ASN Performance (Case Studies in 4 Sub-Districts) of Lubuklinggau City. Data collection techniques in this study used a questionnaire method. Using SPSS 17.0 Program assistance. Data analysis techniques used are Multiple Linear Regression Analysis, Determination Coefficient (R2), and Test F. From the results of the Multiple Regression Analysis obtained the equation Ŷ = 0.448 + 0.617 X1 + 0.379 X2. Furthermore, from the determinant analysis obtained R square value (R2) of 0.867 or 86.7%. This value gives the meaning that Leadership (X1) and Work Communication (X2) contributed an influence of 86.7% on ASN (Y) Performance. While the remaining 13.3% is influenced by other variables not included in this study. Based on the Anova calculation (F test), it is seen that the Fcount value is 169,645 with a significant level of 0,000 while Ftable with α = 5% and (nk-1) or (55-2-1) = 52. And the numerator (k-2 ) is 3,175. Fcount (169,645) > Ftable (3,175), meaning Ho is rejected and Ha is accepted. This shows that there is a significant influence between Leadership and Work Communication on ASN Performance.

This study examined the influence of board gender diversity on the firm performance.the research sample use property and health companies listed in Indonesia stock exchange 2015-2018. total 30 companies. use quantitative methodology with panel regression data analysis techniques were used in this study. The results showed that the gender diversity of the board of commissioners did not have a positive effect on company performance (H1 was rejected) while the gender diversity of the board of directors had a negative effect on company performance (H2 rejected). SIZE and ID control variables also showed significant effect on company performance. For further research it is recommended to use two other methods such as Dummy or gender proportion to measure gender diversity so that the results can be compared, as well as more research data.

The objective of this paper is to present the results of preliminary study that has been performed to measure the reliability of the questionnaire for collecting the quantitative data for the proposed security model of online shopping satisfaction. This paper is endeavours of our previous paper, in which we have developed the research model. Quantitative methodology was adopted to conduct the study by collecting the data through survey questionnaire based on five point Likert scale. Statistical Package for the Social Sciences (SPSS) version 23.0 was used to analyse the data. Results shows that the Cronbach’s alpha value to ensure the reliability of the items is ≥ 0.7, It means all our variables are acceptable for the further studies and for the actual data collection. This paper conclude that the pilot study is necessary phase to conduct before going to collect the actual data in order to avoid any ambiguity in items. Although the sample data is small for the pilot study still, it shows the strength between the related items.

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.

A new strain of mice, which had arisen by mutation from a dystrophic mouse colony was designated ‘mdx’, because the genetic defect, which manifests itself in brief periods of muscle destruction followed by episodes of muscle regeneration appears to be X-linked. Further studies of histopathological changes in muscle from ‘mdx’ mice at the light microscopic or electron microscopic levels have been published, but only one preliminary study has been on the tibialis anterior (TA) of ‘mdx’ mice less than four weeks old. Lesions in the ‘mdx’ mice vary between different muscles, and centronucleation of fibers in all muscles studied so far appears to be especially prominent in older mice. Lesions in young ‘mdx’ mice have not been studied extensively, and the results appear to be at variance with one another. The degenerative and regenerative aspects of the lesions in the TA of 23 to 26-day-old ‘mdx’ mice appear to vary quantitatively.

Spectrum-imaging is a useful technique for comparing different processing methods on very large data sets which are identical for each method. This paper is concerned with comparing methods of electron energy-loss spectroscopy (EELS) quantitative analysis on the Al-Li system. The spectrum-image analyzed here was obtained from an Al-10at%Li foil aged to produce δ' precipitates that can span the foil thickness. Two 1024 channel EELS spectra offset in energy by 1 eV were recorded and stored at each pixel in the 80x80 spectrum-image (25 Mbytes). An energy range of 39-89eV (20 channels/eV) are represented. During processing the spectra are either subtracted to create an artifact corrected difference spectrum, or the energy offset is numerically removed and the spectra are added to create a normal spectrum. The spectrum-images are processed into 2D floating-point images using methods and software described in [1].

In the last twenty years, a significant amount of work has been done in the theoretical understanding of grain boundaries. The various proposed grain boundary models suggest the existence of coincidence site lattice (CSL) boundaries at specific misorientations where a periodic structure representing a local minimum of energy exists between the two crystals. In general, the boundary energy depends not only upon the density of CSL sites but also upon the boundary plane, so that different facets of the same boundary have different energy. Here we describe TEM observations of the dissociation of a Σ=27 boundary in silicon in order to reduce its surface energy and attain a low energy configuration.The boundary was identified as near CSL Σ=27 {255} having a misorientation of (38.7±0.2)°/[011] by standard Kikuchi pattern, electron diffraction and trace analysis techniques. Although the boundary appeared planar, in the TEM it was found to be dissociated in some regions into a Σ=3 {111} and a Σ=9 {122} boundary, as shown in Fig. 1.

Ion mills equipped with flood guns can perform two important functions in material analysis; they can either remove material or deposit material. The ion mill holder shown in Fig. 1 is used to remove material from the polished surface of a sample for further optical inspection or SEM ( Scanning Electron Microscopy ) analysis. The sample is attached to a pohshing stud type SEM mount and placed in the ion mill holder with the polished surface of the sample pointing straight up, as shown in Fig 2. As the holder is rotating in the ion mill, Argon ions from the flood gun are directed down at the top of the sample. The impact of Argon ions against the surface of the sample causes some of the surface material to leave the sample at a material dependent, nonuniform rate. As a result, the polished surface will begin to develop topography during milling as fast sputtering materials leave behind depressions in the polished surface.

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.
