Identification through animal hair character is one of a very important forensic tool given the high level of animal trade in Indonesia, one of which is the deer family (Cervidae). Indonesia has four species of Cervidae, there are Rusa timorensis (Javan deer), Rusa unicolor (Sambar deer), Muntiacus muntjak (Barking deer) and Axis kuhlii (Rusa Bawean). Until now, no information about the morphological character of Indonesian cervidae’s hair. In this study, we used 30 shaft/individual/species from Javan deer (8 individuals), Sambar deer (5 individuals), Barking deer (5 individuals) and Bawean deer (5 individual) from specimens collection of Museum Zoologicum Bogoriense (MZB) and field collections. Hairs were analyzed for macroscopic and microscopic, with several parameters of morphology, cuticular structure, medula, cross-section, and medullary index. The result showed that the special character of this family was filled lattice medulla structure and can be used for species  identification.

<p><strong>Abstract.</strong> Lava dome changes detection during increasingly high volcanic activity are essential for hazard assessment purposes. However, it is challenging to conduct direct field measurement due to safety reason. Here, we investigate the lava dome changes of Mount Agung in Indonesia during the highest level of volcanic activity. On 22 September 2017, the rumbling and seismic activity in this volcano started increasing to the highest level for a period of time. We afterwards collected image data at lava dome area by using UAV over this time period. To accomplish the goal of change detection, we assembled and developed a fixed-wing UAV platform, i.e. Buffalo FX-79 to acquire images of Mount Agung whose elevation is roughly 3,142&amp;thinsp;m above sea level. We acquired the UAV images on two dates, i.e. Oct 19 and Oct 21 of 2017. Due to an exclusion zone surround the volcano, we could only operate the UAV at 20&amp;thinsp;km distance from the crater. With these data set, we produced three-dimensional point clouds, high-resolution Digital Elevation Model and orthophoto by using Structure from Motion (SfM) and Multi View Stereo (SfM-MVS) technique with Photoscan Pro software. From orthophoto data, we found two fluid areas at the crater's surface in NE direction (4,375.9&amp;thinsp;sq-m) and SE direction (3,749.8&amp;thinsp;sq-m). We also detected a fumarole which emitted steam and gases in the eastern part that continued for several days. In order to reveal the changes in lava dome surface, we used DEM to create cross-section profile. After that, we applied cloud to cloud comparison (C2C) algorithm to calculate the difference of lava dome based on two data set of point clouds and compared it with interferometric result from Sentinel-1A data. The data from the Sentinel-1A satellite (15 Oct &amp;ndash; 27 Oct 2017) were processed to obtain the interferogram image of Mount Agung. This research therefore demonstrates a potential method to detect lava dome changes during high level of volcanic activity with photogrammetric methods by using UAV images. Within only two days the data were successfully acquired. From the DEM data and cross-section profile between two data set, we noticed that no significant surface change was found around the lava dome surface. Moreover, we also found that there was no significant lava dome changes and vertical displacement during these two time periods as the point cloud comparison and distance result. The average of difference distance is 2.27&amp;thinsp;cm with a maximal and minimal displacement of 255&amp;thinsp;cm and 0.37&amp;thinsp;cm respectively. This result was then validated by using InSAR Sentinel that showed small displacement, i.e 6.88&amp;thinsp;cm. It indicated that UAV photogrammetry showed a good performance to detect surface changes in centimeter fraction.</p>

A numerical investigation on the harmonic disturbances in low-voltage cables feeding large LED loads is reported. A frequency domain analysis on several commercially-available LEDs was performed to investigate the signature of the harmonic current injected into the power system. Four-core cables and four single-core cable arrangements (three phases and neutral) of small, medium, and large conductor cross sections, with the neutral conductor cross section approximately equal to the half of the phase conductors, were examined. The cables were modelled by using electromagnetic finite-element analysis software. High harmonic power losses (up to 2.5 times the value corresponding to an undistorted current of the same rms value of the first harmonic of the LED current) were found. A generalized ampacity model was employed for re-rating the cables. It was found that the cross section of the neutral conductor plays an important role in the derating of the cable ampacity due to the presence of a high-level of triplen harmonics in the distorted current. The ampacity of the cables should be derated by about 40 %, almost independent of the conductor cross sections. The calculation have shown that an incoming widespread use of LED lamps in lighting could create significant additional harmonic losses in the supplying low-voltage lines, and thus more severely harmonic emission limits should be defined for LED lamps.

This study obejctives to determine the distribution maps and identify the morphological character of local Mangga Podang at five sub-districts in Kediri. This research used purposive sampling method for collecting data. Coordinate of local mango wasanalyzed using QGIS software version 3.6. Morphological characters are examined by observing the morphology. Microclimate factors that were measured are altitude, intensity, temperature and moisture of soil and air, soil pH, and soil nutrient. Morphological characterswere analyzed for homogenity by statistical test. The results showed that Mangga Podang distribution has spread in residential areas and has different altitude factors between 85-459 meters above sea level. The total population(individu/400m2) found in this study were Mojo10(11.2%), Banyakan 17 (19.1%), Grogol8 (9%), Semen 3 (3,4%)and Tarokan51 (57.3%). Mangga Podangof Kediri Regency generally have homogenous morphological characters, but there were the special character which differs each other, they are the number of flowers in 1 panicle, the weight of ripe fruit and exocarp color of ripe fruits. This morphological variation dependent to light intensity, altitudinal, the velocity of wind and soil nutrient factors.

Fossil raninid crabs, Cretacoranina punctata (Rathbun, 1935), from the Pawpaw Formation (Upper Cretaceous) of Fort Worth, Texas, exhibit an unusual cuticular morphology. Comparison of the cuticle of extant Raninoides louisianensis to that of C. punctata reveals general similarities in endocuticular, exocuticular, and epicuticular ultrastructure; however, their gross morphology is strikingly different. The surface of the carapace of C. punctata appears pebbled, much like the surface of a basketball, with closely packed, hexagonal caps. In cross-section, these caps are the upper portion of fungiform structures within convoluted exocuticle. Along the anterior margin, anterolateral margins, and pterygostomial region of the carapace of C. punctata each cap dips slightly posteriorly, creating a series of tiny terraces. In contrast to terrace lines, questa lines, spines, and nodes that provide frictional resistance in interactions with coarse-grained sediments, the fine relief and contouring of the pebbled surface of the carapace of C. punctata provides frictional resistance in interactions with fine-grained sediments. Cretacoranina dichrous, C. trechmanni, C. testacea, and C. schloenbachi, as well as Eucorystes carteri were all found to possess variations of the exocuticular structures seen on C. punctata. This pebbled surface has not been recognized in any other decapod taxon, nor has its structure and function been described previously.

AbstractIn this work, one intends to computationally simulate and investigate, via thermochemical calculations, how the chemical environment influences some molecular properties, such as IR spectra and absorption cross section, of individual species embedded in the solid phase employing the Polarized Continuum Model (PCM) approach. The trial molecules used here to check these effects are CO, CO2 and H2O. The solid phase (bulk ice) is simulated using different dielectric constant values representing different types of astrophysical ice at PCM approach. The effect of temperature is also investigated since it is known it affects the dielectric constant of the solvent medium.

1. Superphosphate, at two levels and three intervals of application, was applied to calcareous downland pasture grazed by sheep over a period of 3 years.2. At the high level, total dry-matter and crudeprotein yields were higher from a single initial application and from thrice-yearly applications than from annual applications.3. At the high level, mean herbage phosphate content and total phosphate yield were higher following a single initial application than when superphosphate was applied at shorter intervals.4. Superphosphate increased the cover of grasses and legumes and reduced the cover of herbs.5. Superphosphate affected the cover of individual species in the following manner:(a) Favourably: Dactylis glomerata, Festuca rubra, Arrhenatherum elatius, Poa trivialis, Holcus lanatus, Lolium perenne and Trifolium repens.(b) Unfavourably: Agrostis stolonifera, Leontodon spp., Prunella vulgaris, and other minor herbs.(c) No measurable effect: Poa pratensis, Plantago lanceolata, Ranunculus bulbosus and Crepis capillaris.

Abstract Dance is an artistic genre that is more and more frequently used in theatre productions. The syncretism of theatre and dance can take many shapes, from inserting dance sequences in dramatic performances, to new artistic genres, such as dance theatre. Due to the fact that they offer manifold innovating possibilities for artistic expression in a greatly audience-oriented universal language, theatrical forms that include dance, and especially the artistic genre of dance theatre are increasingly often put on stage by directors who work in Romania. Thus, training actors in the area of dance at a high level of performance that allows them to approach these types of syncretic artistic genres becomes a priority for the Romanian theatre school. The director, one of the stakeholders in higher education theatre schools, is the one who decides both the form of a performance and an actor’s involvement (or lack thereof) in that certain performance. Limited or stimulated by the actor’s training level, the director is also a beneficiary of the education the acting student receives in drama school. This study aims at identifying the opinions of ten Romanian directors on the matter of the choreographic categories and skills the acting student acquires during his years of training at a higher education institution. We have used qualitative methodology research, based on semi-structured interviews, applied to a cross-section of ten directors from Bucharest, Cluj-Napoca, Constanţa, Craiova, Iaşi, and Tg. Mureş. This article tackles the issue of cognitive didactic objectives and students’ cognitive competencies that have been emphasized during the conversations with the aforementioned directors.
