The stimulus was a vertical, straight, red line which for 60 msec. was projected onto a medium grey screen 2 m. from S. In Exp. I the line was 8.5 cm. long and 2 mm. wide; in Exp. II the line was 17 cm. long and 2 mm. wide. Fixating the nethermost point of the short and long lines, respectively, Ss reported experiencing the line as lengthening from the point of fixation to full length and then shortening to the point of fixation. Ss' durations of experienced lengthening-shortening were measured (in msec.). For a given S the durations of lengthening-shortening of the 8.5-cm. line and the 17-cm. line were identical. Ss reported that the velocity of the experienced movement (lengthening-shortening) of the long line was greater than that of the short line. When 12 Ss were retested from 6 to 8 mo. later, their durations remained constant. Barbiturate caused a significant increase in durations of lengthening-shortening. This is consistent with the notion that the source of experienced lengthening-shortening is to be found in cortical brain processes. An electronic explanation of the experienced movement as a working hypothesis is offered.

The stimulus was a vertical, straight, red line, 17 cm. long and about 2 mm. wide, which for 60 msec. was projected onto a medium grey screen 2 m. from S. Fixating the midpoint of the line S reported that the line lengthened upwards and downwards from the point of fixation to full length and then shortened to the point of fixation. The measured time of lengthening-shortening with fixation of the midpoint was identical with that of fixation of the nethermost point of the same line.

Sei Nagalawan village is one of the coastal villages in Perbaungan district, Serdang Bedagai regency that has the potential of mangrove ecosystems. Some fishermans in this village use pedada fruit (Sonneratia caseolaris L.) to be processed commercially into pedada syrup. Pedada syrup is marketed in mangrove tourist sites of Kampung Nypah and around Perbaungan district. This research aimed to analyze the financial feasibility, flow and marketing margins of the pedada syrup making business conducted by the Sei Nagalawan village community. The method used is quantitative descriptive analysis on the business actors processing, distribution and marketing of pedada syrup. The results showed that the business of making pedada syrup was feasible with an R/C ratio of 5, a break event point of 17 bottles and a payback period of 2 production cycles. The marketing flow of the pedada syrup business consists of 2 channels, namely the short line (direct) marketing channel and the long line marketing channel. The profit margin obtained by the producer through the short line marketing channel is IDR. 9.000,-/bottle. In the long line marketing channel, the margin obtained by producers is IDR. 6.000,-, collectors of IDR. 1,000, and retailers IDR. 2,000,per bottle.

The stimulus was a vertical, straight, red line, 17 cm. long and about 2 mm. wide, which for 60 msec. was projected onto a medium grey screen 2 m. from S. Fixating the nethermost point of the line S experienced that the line grew from the point of fixation to full length in order and then decreased in length to the point of fixation. The experienced time of lengthening-shortening, which on an average was about 570 msec. for 37 Ss, was measured by means of a special methodology. At measurable time of lengthening-shortening of Ss' experiences of the line were a regular oscillating phenomenon of perception. We have sought a functional relation between the oscillating phenomenon of perception mentioned and the oscillating processes of the brain.

ABSTRAKPola lantai Tari Rejang Sakral Lanang di Desa Mayong berkonsep rwa bhinedha yang terlihat dari garis lurus satu banjar lalu membentuk garis melengkung. Kedua garis tersebut merupakan simbol purusa dan pradana untuk mencapai suatu kehidupan atau keseimbangan. Tujuan penelitian ini adalah mengetahui konsep rwa bhinedha dalam pola lantai tarian tersebut. Teknik pengumpulan data penelitian ini adalah metode observasi tidak berstruktur, metode wawancara, studi dokumentasi, dan studi kepustakaan. Berdasarkan analisis data yang dilakukan, diperoleh hasil bahwa pola lantai Tari Rejang Sakral Lanang di Desa Mayong pada saat pementasan menggunakan konsep rwa bhinedha yang dilakukan di Jaba Tengah berbentuk kalangan pada setiap pura (Kahyangan Desa) yang terdapat di Desa Mayong. Pola lantai hanya terdiri dari satu banjar panjang yang membentuk garis lurus dan melengkung di dalamnya. Penelitian ini menggunakan Teori Semiotika dari Ferdinand de Saussure yaitu penanda dan petanda. Garis lurus dan garis melengkung yang membentuk lingkaran pada pola lantai sebagai penanda dan petanda adalah garis lurus tersebut merupakan simbol purusa dan garis lengkung merupakan simbol pradana. Kedua garis tersebut merupakan bagian dari konsep rwa bhinedha. ABSTRACT The floor pattern of the Rejang Sakral Lanang Dance in Mayong Village has a rwa bhinedha concept which is seen from a straight line and forms a curved line. Both of these lines are purusa and pradana symbols to achieve a life or balance. The purpose of this study was to determine the concept of rwa bhinedha in the dance floor pattern. The research data collection techniques are unstructured observation methods, interview methods, documentation studies, and library studies. Based on the data analysis, the results showed that the floor pattern of the Lanang Sacred Rejang Dance in Mayong Village during the staging used the concept of rwa bhinedha which was carried out in Jaba Tengah in the form of circles in each temple (Kahyangan Desa) located in Mayong Village. The floor pattern consists of only one long line that forms a straight and curved line in it. This study uses the Semiotics Theory of Ferdinand de Saussure namely markers and markers. Straight lines and curved lines that form a circle on the floor pattern as markers and markers are straight lines are symbols of the purusa and curved lines are symbols pradana. These two lines are part of the concept of rwa bhinedha.

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.

Domains visible by transmission electron microscopy, believed to be Dauphiné inversion twins, were found in some specimens of synthetic quartz heated to 680°C and cooled to room temperature. With the electron beam close to parallel to the [0001] direction the domain boundaries appeared as straight lines normal to <100> and <410> or <510> directions. In the selected area diffraction mode, a shift of the Kikuchi lines was observed when the electron beam was made to traverse the specimen across a boundary. This shift indicates a change in orientation which accounts for the visibility of the domain by diffraction contrast when the specimen is tilted. Upon exposure to a 100 KV electron beam with a flux of 5x 1018 electrons/cm2sec the boundaries are rapidly decorated by radiation damage centers appearing as black spots. Similar crystallographio boundaries were sometimes found in unannealed (0001) quartz damaged by electrons.

Peroxisome proliferator-activated receptor gamma (PPARg) is a member of the nuclear hormone receptor superfamily and has been shown in vitro to regulate genes involved in lipid metabolism and adipocyte differentiation. By Northern analysis, we and other researchers have shown that expression of this receptor predominates in adipose tissue in adult mice, and appears first in whole-embryo mRNA at 13.5 days postconception. In situ hybridization was used to find out in which developing tissues PPARg is specifically expressed.Digoxigenin-labeled riboprobes were generated using the Genius™ 4 RNA Labeling Kit from Boehringer Mannheim. Full length PPAR gamma, obtained by PCR from mouse liver cDNA, was inserted into pBluescript SK and used as template for the transcription reaction. Probes of average size 200 base pairs were made by partial alkaline hydrolysis of the full length transcripts. The in situ hybridization assays were performed as described previously with some modifications. Frozen sections (10 μm thick) of day 18 mouse embryos were cut, fixed with 4% paraformaldehyde and acetylated with 0.25% acetic anhydride in 1.0M triethanolamine buffer. The sections were incubated for 2 hours at room temperature in pre-hybridization buffer, and were then hybridized with a probe concentration of 200μg per ml at 70° C, overnight in a humidified chamber. Following stringent washes in SSC buffers, the immunological detection steps were performed at room temperature. The alkaline phosphatase labeled, anti-digoxigenin antibody and detection buffers were purchased from Boehringer Mannheim. The sections were treated with a blocking buffer for one hour and incubated with antibody solution at a 1:5000 dilution for 2 hours, both at room temperature. Colored precipitate was formed by exposure to the alkaline phosphatase substrate nitrobluetetrazoliumchloride/ bromo-chloroindlylphosphate.
